prognostic factors of lung cancer

7 de janeiro de 2021

The factors with statistical significance that affected lung cancer-specific survival (LCSS) and overall survival (OS) were included in the final prediction model. The median number of factors reported to be significant in multivariate analyses per study was 2 (range, 0 to 6 factors). Women with lung cancer have a slightly better prognosis than men who are diagnosed with the same cancer. Rawson NSB, Peto J (1990) An overview of prognostic factors in small cell lung cancer: a report from the Subcommittee for the Management of Lung Cancer of the United Kingdom Coordinating Committee on Cancer Research. Performance status measures how well a person can do their daily activities and everyday tasks. These studies have been meta-analysed and this review has shown that high metabolic activity is indeed an univariate prognostic factor (estimated hazard ratio of 2.08). Pretreatment PNI can better predict the prognosis of SCLC, especially in patients with age ≤ 60, no smoking history, … BACKGROUND/AIM: Only 0.1-0.17% of all lung cancer patients are diagnosed with stage I or II small cell lung cancer (SCLC). Canadians can help CCS fund the best research and support people living with cancer by donating and volunteering. In each of three randomised phase-III studies, a treatment interaction effect with histology has been identified [42]. Introduction. Examples of scales used to evaluate performance status include the Eastern Cooperative Oncology Group (ECOG), World Health Organization (WHO) and the Karnofsky performance status scale. In resected patients, some publications have looked at genetic signatures, most often using small-to-moderate series of patients divided into training and validation sets. Multiplicity testing and over-fitting may prevent reproducibility of the models in external validation series. So, EGFR has become the first molecular target in advanced non-small cell lung cancer that is definitely of clinical usefulness in routine practice [47–53]; it is now a standard treatment to give patients with EGFR mutation a TKI as part of their first-line treatment although there still remains a role for chemotherapy [54]. A meta-analysis of individual data showed that Cyfra 21-1 level has also an independent prognostic value [16]; anaemia was also shown as an independent prognostic factor in patients with cancer, especially in patients with lung cancer in a systematic quantitative review [17]. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Surgical procedures more extended than lobectomy might also be indicative of a poor prognosis but this variable might just be correlated with other factors that led to the decision of the type of surgery [12]. People who have lost more than 5% of their body weight before treatment starts have a less favourable prognosis than people who haven’t lost much weight. Lung cancers that have certain genetic changes may respond better to treatments that are designed to target that specific change. Nico Van Zandwijk, MD, PhD. Other negative prognostic factors included increased age and men for the LD‐SCLC group and increased age, men, increased number of metastatic sites at baseline, … Numerous studies have looked at the prognostic value of tumor metabolic activity as measured by [F]-fluoro-2-deoxy-d-glucose positron emission tomography. In both men and women, lung cancer is the most common malignancy and accounts for 18% of deaths worldwide [1] . The true predictive factor was identified later [46]; the subgroup of patients who benefit in terms of progression-free survival from TKIs were those with somatic mutations in the EGFR gene (exons 19 and 21). Among 132 patients who were diagnosed with pathological N1 lung cancer at a single institution from January 2010 to December … The pathologic staging of non–small cell lung cancer (NSCLC) is a key determinant of the patient's prognosis and the treatment options. Patients heavily pre-treated were investigated for 11 biomarkers and four different targeted treatments. They provide however very promising results. Huaxia Yang 1#, Zhuoran Yao 1#, Xiaoxiang Zhou 1#, Zhongxing Bing 2, Lei Cao 2, Zhili Cao 2, Shanqing Li 2, Xuan Zhang 1, Yan Zhao 1, Xiaofeng Zeng 1, Fengchun Zhang 1, Naixin Liang 2.

In more advanced non-resectable disease, a younger age might be a feature of better prognosis although competing risks might have a higher impact on mortality in older patients. Then we established the nomogram for predicting 1-, 3- and 5-year survival rates in SCC patients using these identified prognostic factors. The following features have been suggested to be associated with a more favourable prognosis: p53 normal status [18]; no EGFR expression [19]; low microvessel count [20]; low VEGF expression [21]; no overexpression of c-erbB-2 [22] with an effect possibly restricted to non-squamous histology [23]; Bcl-2 expression [24]; low KI67 expression [25]; absence of KRAS mutation [26]; TTF-1 positivity [27]; high level of p16 expression [28]; low or no ERCC1 expression (advanced NSCLC treated with platinum-based chemotherapy) [29]; low class III β-tubulin expression, in resected patients [30]; low survivin expression, in resected patients only [31]; and low lymphatic microvessel density, in surgically treated patients [32].

Most often, these factors are not reproducible and their prognostic independent value is not proven, with adjustment for well-known prognostic factors. Depending on the population studied (small cell or non-small cell cancer, operable or not) other independent factors, identified in large series, improve the prediction of prognosis: sex, age, loss of weight, LDH, leukocytosis, neutrophilia, haemoglobin, serum calcium, NSE, Cyfra 21-1. But the recognition and identification of a predictive factor is not so straightforward and some new drugs have been developed without specifically knowing the target or without having available a method to measure the target with adequate reproducibility. Quality of life in lung cancer patients: as an important prognostic factor. Introduction : Lung cancer is one of the most frequently occurring neoplasms and usually has a poor prognosis because most of the patients present with advanced or metastatic disease at the time of diagnosis. © 2021 Canadian Cancer Society All rights reserved. In fact, lung cancer patients are usually life-long smokers and present many comorbidities. Toshi Menju, Toshi Menju Department of Thoracic Surgery, Graduate School of … The efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) for EGFR-mutated non-adenocarcinoma (ADC) non-small cell lung cancer patients is not well established.Herein, we investigated key prognostic factors influencing the efficacy of … The predictive value remains to be further investigated [59]. Adjuvant chemotherapy provides a demonstrated benefit in overall survival when given to resected patients but brings also some toxicities. These innovations were informed by an analysis of data from the International Association for the Study of Lung Cancer (IASLC) database that included 70,967 evaluable patients with non-small cell lung cancer and 6,189 with small cell lung cancer. PATIENTS AND METHODS: Seven factors in eight patients with early stage SCLC were analyzed concerning the impact … Predictive factors are more directly useful in clinical practice as they are directly related to the efficacy of a specific treatment. lung cancer; prognostic factor; surgical specimen; immunohistochemical staining; Lung cancer is now the leading cause of cancer death throughout the world. how well you and the cancer respond to treatment; other factors such as your age, fitness and overall health, and whether you’re currently a smoker. In the present study, we calculated a prognostic index for predicting overall survival (OS) in NSCLC patients. Most of the predictive factors are molecular biological factors but this is not always the case. Those signatures are not ready for use in clinical practice. Online ISSN: 2073-4735, Copyright © 2021 by the European Respiratory Society. Prognostic factors related to postoperative survival in the newly classified clinical T4 lung cancer Keiji Yamanashi, Keiji Yamanashi Department of Thoracic Surgery, Graduate School of Medicine, Kyoto University , Kyoto, Japan. A recent meta-analysis [61] also comes to the same conclusion, although through indirect comparisons, that patients treated with cisplatin-based chemotherapy and high ERCC1 expression have worse survival than patients with low expression of ERCC1 (HR 1.61, 95% CI 1.23–2.10) while this is not true when no chemotherapy is given (HR 0.80; 95% CI 0.51–1.31). They both play a part in deciding on a treatment plan and a prognosis. Its expression is mutually exclusive from expression of KRAS and EGFR; it has no prognostic value but it is a predictive factor for efficacy of the ALK inhibitor crizotinib. People with lung and heart problems have a less favourable prognosis when diagnosed with lung cancer. 14-17, 20 In addition, the number of metastases, 13, 19 achievement of complete resection, 14 estrogen‐receptor status, 19 and the initial breast‐cancer stage 17 have been studied as possible prognostic factors for survival after pulmonary metastasectomy. [38] published a 15-gene signature with a larger effect in resected patients, independent from stage with an overall HR of 15.02 (95% CI 5.12–44.04) with consistent results in stage I and stage II. People who are in better overall health are more likely to be able to have surgery to remove the lung cancer, which may improve survival. Further studies, either subgroups analyses of the first randomised trials or randomised trials having used of an enrichment design (i.e. Aim: Study the prognostic factors in non small-cell lung cancer. The predictive role of RRM1 for sensitivity to gemcitabine, an antimetabolite frequently used in combination with platinum has been recently studied in the context of a randomised trial comparing cisplatin, docetaxel and gemcitabine to cisplatin–vinorelbine. [1], in a systematic overview of prognostic factors for non-small cell lung cancer, identified 887 articles published during a decade and more than 150 possible prognostic factors for non-small cell lung cancer. Thank you for your interest in spreading the word on European Respiratory Society . Prognostic factors are very useful to get information about disease evolution and to construct homogeneous groups of patients. A predictive factor influences how a cancer will respond to a certain treatment. It was hypothesised that not all patients benefit from adjuvant chemotherapy and some biomarkers have been studied in order to identify subgroups of sensitive patients. Blood vessel invasion is associated to an increased risk of relapse and death as shown by a meta-analysis (multivariate combined hazard ratio for relapse free survival 3.98 (95% CI 2.24–7.06) and for survival 1.90 (95% CI 1.65–2.19)) [15]. Recently, within the IASLC Lung Cancer Staging Project, data concerning 12,620 small cell lung cancer cases were collected and complete clinical TNM staging was available for 3,430 cM0 patients as well as complete pathologic TNM staging for 343 cases. dL−1) might be associated with a higher mortality and preoperative high Cyfra 21-1 level has been associated with higher risk of relapse [14]. The stage of lung cancer is the most important prognostic factor. Prognostic Factors and Biomarkers of Responses to Immune Checkpoint Inhibitors in Lung Cancer Andrea Bianco 1,2,*, Fabio Perrotta 3, Giusi Barra 4, Umberto Malapelle 5, Danilo Rocco 2 and Ra aele De Palma 4 1 Department of Translational Medical Sciences, University of Campania “L Vanvitelli”, 80131 Naples, Italy 2 Department of Pneumology and Oncology, A.O. Further consensus about the adequate methodology to search and identify new prognostic factors is lacking; indeed, we have no agreement on the set of factors that should systematically be used to adjust the effect of new factors and how to assess what independent additional value a new factor brings. The authors concluded that the TNM stage should be used to stratify in clinical trials patients with stages I–III. However, when using current staging and prognostic indices, the prognosis can vary significantly. dei Colli, Hosp. Although very interesting and promising, the additional prognostic value should be validated with adjustment for classical prognostic factors. 2021 Jan 1;12(3):885-898. doi: 10.7150/jca.50274. They may also be able to tolerate chemotherapy and radiation better than people in poor health. Google Scholar. Many factors may influence lung cancer survival, including gender [ 2, 3 ], diagnostic age [ 4, 5 ], histological type [ 6, 7 ], and treatment modality [ 8 – 10 ]. These studies are extremely important as chemotherapy remains a cornerstone in the treatment of early or advanced non-small cell lung cancer. Numerous prognostic factors (PF) have been studied. Lung cancer is the most common malignancy in the world and accounts for the majority of cancer-related mortality. We do not capture any email address. The aim of the present study was to assess the outcome of lung cancer patients who were admitted to a medical intensive care unit (MICU) and to identify the measurable predictors of their MICU outcome. The Role of Prognostic Factors and Oncogenes in the Detection and Management of Non-Small-Cell Lung Cancer. Most of the research carried out on predictive factors in lung cancer has been devoted to non-small cell lung cancer and we will restrict this review to non-small cell lung cancer. [38] as prognostic might also be predictive of a benefit reached with adjuvant chemotherapy (cisplatin and vinorelbine) in stage IB and II resected patients. Radiochemotherapy remains the standard treatment for limited stage disease. Regarding the prognostic value of angiogenesis, microvessel count was confirmed as prognostic factor in a meta-analysis based on individual data, only if assessed by the Chalkley method [33]. The retrospective study took place at the MICUs of a university-affiliated medical centre and involved adult lung cancer patients admitted to the MICU between January 1998 and October 2005. Survival and prognostic factors of lung cancer patients with preexisting connective tissue disease: a retrospective cohort study. Survival of cancer patients is one of the main quality indicators of the health care system since it reflects the extent to which cases are diagnosed at a potentially curable stage and also measures the effectiveness of the therapeutic procedure. Furthermore, non-small cell lung cancer (NSCLC) has the highest prevalence rate but only a 14% 5-year survival rate in patients subjected to surgery ().So far, considerable progress has been made to identify the local environmental factors that promote tumor progression. Pei-Pei Wang 1,4*, Si-Hong Liu 2,4*, Cun-Te Chen 3,4*, Lin Lv 1,4, Dan Li 1,4, Qiong-Yao Liu 1,4, Guo-Long Liu 1,4 , Yong Wu 1,4 . They are however not powerful enough to be used at the individual level. Limited stage small cell lung cancers have a much better prognosis than extensive stage cancers. The main poor prognostic factors identified were DAD‐like pattern (highest hazard ratio: 10.72), ≤60 days from start of nivolumab treatment to onset of ILD, pleural effusion before treatment, lesion distribution contralateral or bilateral to the tumor, and abnormal change in C‐reactive protein (CRP) levels. For example, on resected patients, Chen et al. Early stages of lung cancer (stages 0 and 1) have a better prognosis than later stages (stages 2, 3 or 4). Circulating tumor cells as a new predictive and prognostic factor in patients with small cell lung cancer . Other parameters from molecular biology like BCL2 expression, p53 normal status or no overexpression of HER2 [23] have been suggested but evidence is less clear. Median survival times in months were the following: IA: 26; IB: 21; IIA: 15; IIB: 12; IIIA: 13; IIIB: 11; and IV: 6. To evaluate treatment outcomes and prognostic factors in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiation. It is important to know that although the statistics for lung cancer can be frightening, they are an average and may not apply to your situation. The KRAS pathway links the EGFR pathway to cell proliferation and survival and KRAS mutations have been suggested as a mediating resistance to EGFR mediators. Among routine biological parameters, normal leukocytosis and normal neutrophil count, lactate dehydrogenase (LDH) level, calcaemia, haemoglobinaemia and albuminaemia have been identified as favourable independent prognostic factors. Although the analysis was retrospectively done on a subgroup of 261 patients (out of the 443 randomised), the results suggest, surprisingly, that the predictive role of RRM1 is present for sensitivity to cisplatin–vinorelbine with better outcomes observed for RRM1-negative patients (better disease control rate, better progression free survival (6.9 months versus 3.9 months; p<0.001), better overall survival (11.6 months versus 7.4 months; p = 0.002) [63]. The signature proposed by Zhu et al. PubMed. Advances in Lung Cancer, 7, 21-31. doi: 10.4236/alc.2018.73003. Despite recent improvements in its treatment, the prognosis for lung cancer patients remains poor.

[37] derived a five-gene signature with impressive hazard ratio between low- and high-risk patients: 3.36 for overall survival (95% CI 1.35–8.35; p = 0.009) in the validation series (n = 86). PNI was a good biomarker for the assessment of SCLC prognosis for its easy access, convenience to be calculated, and low consumption. This study was devoted to identify glycolysis related genes as prognostic biomarkers for non-small cell lung cancer (NSCLC). People with a higher performance status have a better prognosis than people with a lower performance status score. Vascular endothelial growth factor receptors: VEGF and VEGFR-2 were investigated as predictive biomarkers in the BATTLE study (Biomarker-Integrated Approaches of Targeted Therapy for Lung Cancer Elimination).

For example, genetic signatures that might be very promising are not necessarily validated when adjusted for known classical prognostic factors. Br J Cancer 61:597–604 PubMed Google Scholar. This specific target is expected to be a predictive factor.

The factors with statistical significance that affected lung cancer-specific survival (LCSS) and overall survival (OS) were included in the final prediction model. The median number of factors reported to be significant in multivariate analyses per study was 2 (range, 0 to 6 factors). Women with lung cancer have a slightly better prognosis than men who are diagnosed with the same cancer. Rawson NSB, Peto J (1990) An overview of prognostic factors in small cell lung cancer: a report from the Subcommittee for the Management of Lung Cancer of the United Kingdom Coordinating Committee on Cancer Research. Performance status measures how well a person can do their daily activities and everyday tasks. These studies have been meta-analysed and this review has shown that high metabolic activity is indeed an univariate prognostic factor (estimated hazard ratio of 2.08). Pretreatment PNI can better predict the prognosis of SCLC, especially in patients with age ≤ 60, no smoking history, … BACKGROUND/AIM: Only 0.1-0.17% of all lung cancer patients are diagnosed with stage I or II small cell lung cancer (SCLC). Canadians can help CCS fund the best research and support people living with cancer by donating and volunteering. In each of three randomised phase-III studies, a treatment interaction effect with histology has been identified [42]. Introduction. Examples of scales used to evaluate performance status include the Eastern Cooperative Oncology Group (ECOG), World Health Organization (WHO) and the Karnofsky performance status scale. In resected patients, some publications have looked at genetic signatures, most often using small-to-moderate series of patients divided into training and validation sets. Multiplicity testing and over-fitting may prevent reproducibility of the models in external validation series. So, EGFR has become the first molecular target in advanced non-small cell lung cancer that is definitely of clinical usefulness in routine practice [47–53]; it is now a standard treatment to give patients with EGFR mutation a TKI as part of their first-line treatment although there still remains a role for chemotherapy [54]. A meta-analysis of individual data showed that Cyfra 21-1 level has also an independent prognostic value [16]; anaemia was also shown as an independent prognostic factor in patients with cancer, especially in patients with lung cancer in a systematic quantitative review [17]. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Surgical procedures more extended than lobectomy might also be indicative of a poor prognosis but this variable might just be correlated with other factors that led to the decision of the type of surgery [12]. People who have lost more than 5% of their body weight before treatment starts have a less favourable prognosis than people who haven’t lost much weight. Lung cancers that have certain genetic changes may respond better to treatments that are designed to target that specific change. Nico Van Zandwijk, MD, PhD. Other negative prognostic factors included increased age and men for the LD‐SCLC group and increased age, men, increased number of metastatic sites at baseline, … Numerous studies have looked at the prognostic value of tumor metabolic activity as measured by [F]-fluoro-2-deoxy-d-glucose positron emission tomography. In both men and women, lung cancer is the most common malignancy and accounts for 18% of deaths worldwide [1] . The true predictive factor was identified later [46]; the subgroup of patients who benefit in terms of progression-free survival from TKIs were those with somatic mutations in the EGFR gene (exons 19 and 21). Among 132 patients who were diagnosed with pathological N1 lung cancer at a single institution from January 2010 to December … The pathologic staging of non–small cell lung cancer (NSCLC) is a key determinant of the patient's prognosis and the treatment options. Patients heavily pre-treated were investigated for 11 biomarkers and four different targeted treatments. They provide however very promising results. Huaxia Yang 1#, Zhuoran Yao 1#, Xiaoxiang Zhou 1#, Zhongxing Bing 2, Lei Cao 2, Zhili Cao 2, Shanqing Li 2, Xuan Zhang 1, Yan Zhao 1, Xiaofeng Zeng 1, Fengchun Zhang 1, Naixin Liang 2. Enter multiple addresses on separate lines or separate them with commas. In more advanced non-resectable disease, a younger age might be a feature of better prognosis although competing risks might have a higher impact on mortality in older patients. Then we established the nomogram for predicting 1-, 3- and 5-year survival rates in SCC patients using these identified prognostic factors. The following features have been suggested to be associated with a more favourable prognosis: p53 normal status [18]; no EGFR expression [19]; low microvessel count [20]; low VEGF expression [21]; no overexpression of c-erbB-2 [22] with an effect possibly restricted to non-squamous histology [23]; Bcl-2 expression [24]; low KI67 expression [25]; absence of KRAS mutation [26]; TTF-1 positivity [27]; high level of p16 expression [28]; low or no ERCC1 expression (advanced NSCLC treated with platinum-based chemotherapy) [29]; low class III β-tubulin expression, in resected patients [30]; low survivin expression, in resected patients only [31]; and low lymphatic microvessel density, in surgically treated patients [32]. NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Most often, these factors are not reproducible and their prognostic independent value is not proven, with adjustment for well-known prognostic factors. Depending on the population studied (small cell or non-small cell cancer, operable or not) other independent factors, identified in large series, improve the prediction of prognosis: sex, age, loss of weight, LDH, leukocytosis, neutrophilia, haemoglobin, serum calcium, NSE, Cyfra 21-1. But the recognition and identification of a predictive factor is not so straightforward and some new drugs have been developed without specifically knowing the target or without having available a method to measure the target with adequate reproducibility. Quality of life in lung cancer patients: as an important prognostic factor. Introduction : Lung cancer is one of the most frequently occurring neoplasms and usually has a poor prognosis because most of the patients present with advanced or metastatic disease at the time of diagnosis. © 2021 Canadian Cancer Society All rights reserved. In fact, lung cancer patients are usually life-long smokers and present many comorbidities. Toshi Menju, Toshi Menju Department of Thoracic Surgery, Graduate School of … The efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) for EGFR-mutated non-adenocarcinoma (ADC) non-small cell lung cancer patients is not well established.Herein, we investigated key prognostic factors influencing the efficacy of … The predictive value remains to be further investigated [59]. Adjuvant chemotherapy provides a demonstrated benefit in overall survival when given to resected patients but brings also some toxicities. These innovations were informed by an analysis of data from the International Association for the Study of Lung Cancer (IASLC) database that included 70,967 evaluable patients with non-small cell lung cancer and 6,189 with small cell lung cancer. PATIENTS AND METHODS: Seven factors in eight patients with early stage SCLC were analyzed concerning the impact … Predictive factors are more directly useful in clinical practice as they are directly related to the efficacy of a specific treatment. lung cancer; prognostic factor; surgical specimen; immunohistochemical staining; Lung cancer is now the leading cause of cancer death throughout the world. how well you and the cancer respond to treatment; other factors such as your age, fitness and overall health, and whether you’re currently a smoker. In the present study, we calculated a prognostic index for predicting overall survival (OS) in NSCLC patients. Most of the predictive factors are molecular biological factors but this is not always the case. Those signatures are not ready for use in clinical practice. Online ISSN: 2073-4735, Copyright © 2021 by the European Respiratory Society. Prognostic factors related to postoperative survival in the newly classified clinical T4 lung cancer Keiji Yamanashi, Keiji Yamanashi Department of Thoracic Surgery, Graduate School of Medicine, Kyoto University , Kyoto, Japan. A recent meta-analysis [61] also comes to the same conclusion, although through indirect comparisons, that patients treated with cisplatin-based chemotherapy and high ERCC1 expression have worse survival than patients with low expression of ERCC1 (HR 1.61, 95% CI 1.23–2.10) while this is not true when no chemotherapy is given (HR 0.80; 95% CI 0.51–1.31). They both play a part in deciding on a treatment plan and a prognosis. Its expression is mutually exclusive from expression of KRAS and EGFR; it has no prognostic value but it is a predictive factor for efficacy of the ALK inhibitor crizotinib. People with lung and heart problems have a less favourable prognosis when diagnosed with lung cancer. 14-17, 20 In addition, the number of metastases, 13, 19 achievement of complete resection, 14 estrogen‐receptor status, 19 and the initial breast‐cancer stage 17 have been studied as possible prognostic factors for survival after pulmonary metastasectomy. [38] published a 15-gene signature with a larger effect in resected patients, independent from stage with an overall HR of 15.02 (95% CI 5.12–44.04) with consistent results in stage I and stage II. People who are in better overall health are more likely to be able to have surgery to remove the lung cancer, which may improve survival. Further studies, either subgroups analyses of the first randomised trials or randomised trials having used of an enrichment design (i.e. Aim: Study the prognostic factors in non small-cell lung cancer. The predictive role of RRM1 for sensitivity to gemcitabine, an antimetabolite frequently used in combination with platinum has been recently studied in the context of a randomised trial comparing cisplatin, docetaxel and gemcitabine to cisplatin–vinorelbine. [1], in a systematic overview of prognostic factors for non-small cell lung cancer, identified 887 articles published during a decade and more than 150 possible prognostic factors for non-small cell lung cancer. Thank you for your interest in spreading the word on European Respiratory Society . Prognostic factors are very useful to get information about disease evolution and to construct homogeneous groups of patients. A predictive factor influences how a cancer will respond to a certain treatment. It was hypothesised that not all patients benefit from adjuvant chemotherapy and some biomarkers have been studied in order to identify subgroups of sensitive patients. Blood vessel invasion is associated to an increased risk of relapse and death as shown by a meta-analysis (multivariate combined hazard ratio for relapse free survival 3.98 (95% CI 2.24–7.06) and for survival 1.90 (95% CI 1.65–2.19)) [15]. Recently, within the IASLC Lung Cancer Staging Project, data concerning 12,620 small cell lung cancer cases were collected and complete clinical TNM staging was available for 3,430 cM0 patients as well as complete pathologic TNM staging for 343 cases. dL−1) might be associated with a higher mortality and preoperative high Cyfra 21-1 level has been associated with higher risk of relapse [14]. The stage of lung cancer is the most important prognostic factor. Prognostic Factors and Biomarkers of Responses to Immune Checkpoint Inhibitors in Lung Cancer Andrea Bianco 1,2,*, Fabio Perrotta 3, Giusi Barra 4, Umberto Malapelle 5, Danilo Rocco 2 and Ra aele De Palma 4 1 Department of Translational Medical Sciences, University of Campania “L Vanvitelli”, 80131 Naples, Italy 2 Department of Pneumology and Oncology, A.O. Further consensus about the adequate methodology to search and identify new prognostic factors is lacking; indeed, we have no agreement on the set of factors that should systematically be used to adjust the effect of new factors and how to assess what independent additional value a new factor brings. The authors concluded that the TNM stage should be used to stratify in clinical trials patients with stages I–III. However, when using current staging and prognostic indices, the prognosis can vary significantly. dei Colli, Hosp. Although very interesting and promising, the additional prognostic value should be validated with adjustment for classical prognostic factors. 2021 Jan 1;12(3):885-898. doi: 10.7150/jca.50274. They may also be able to tolerate chemotherapy and radiation better than people in poor health. Google Scholar. Many factors may influence lung cancer survival, including gender [ 2, 3 ], diagnostic age [ 4, 5 ], histological type [ 6, 7 ], and treatment modality [ 8 – 10 ]. These studies are extremely important as chemotherapy remains a cornerstone in the treatment of early or advanced non-small cell lung cancer. Numerous prognostic factors (PF) have been studied. Lung cancer is the most common malignancy in the world and accounts for the majority of cancer-related mortality. We do not capture any email address. The aim of the present study was to assess the outcome of lung cancer patients who were admitted to a medical intensive care unit (MICU) and to identify the measurable predictors of their MICU outcome. The Role of Prognostic Factors and Oncogenes in the Detection and Management of Non-Small-Cell Lung Cancer. Most of the research carried out on predictive factors in lung cancer has been devoted to non-small cell lung cancer and we will restrict this review to non-small cell lung cancer. [38] as prognostic might also be predictive of a benefit reached with adjuvant chemotherapy (cisplatin and vinorelbine) in stage IB and II resected patients. Radiochemotherapy remains the standard treatment for limited stage disease. Regarding the prognostic value of angiogenesis, microvessel count was confirmed as prognostic factor in a meta-analysis based on individual data, only if assessed by the Chalkley method [33]. The retrospective study took place at the MICUs of a university-affiliated medical centre and involved adult lung cancer patients admitted to the MICU between January 1998 and October 2005. Survival and prognostic factors of lung cancer patients with preexisting connective tissue disease: a retrospective cohort study. Survival of cancer patients is one of the main quality indicators of the health care system since it reflects the extent to which cases are diagnosed at a potentially curable stage and also measures the effectiveness of the therapeutic procedure. Furthermore, non-small cell lung cancer (NSCLC) has the highest prevalence rate but only a 14% 5-year survival rate in patients subjected to surgery ().So far, considerable progress has been made to identify the local environmental factors that promote tumor progression. Pei-Pei Wang 1,4*, Si-Hong Liu 2,4*, Cun-Te Chen 3,4*, Lin Lv 1,4, Dan Li 1,4, Qiong-Yao Liu 1,4, Guo-Long Liu 1,4 , Yong Wu 1,4 . They are however not powerful enough to be used at the individual level. Limited stage small cell lung cancers have a much better prognosis than extensive stage cancers. The main poor prognostic factors identified were DAD‐like pattern (highest hazard ratio: 10.72), ≤60 days from start of nivolumab treatment to onset of ILD, pleural effusion before treatment, lesion distribution contralateral or bilateral to the tumor, and abnormal change in C‐reactive protein (CRP) levels. For example, on resected patients, Chen et al. Early stages of lung cancer (stages 0 and 1) have a better prognosis than later stages (stages 2, 3 or 4). Circulating tumor cells as a new predictive and prognostic factor in patients with small cell lung cancer . Other parameters from molecular biology like BCL2 expression, p53 normal status or no overexpression of HER2 [23] have been suggested but evidence is less clear. Median survival times in months were the following: IA: 26; IB: 21; IIA: 15; IIB: 12; IIIA: 13; IIIB: 11; and IV: 6. To evaluate treatment outcomes and prognostic factors in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiation. It is important to know that although the statistics for lung cancer can be frightening, they are an average and may not apply to your situation. The KRAS pathway links the EGFR pathway to cell proliferation and survival and KRAS mutations have been suggested as a mediating resistance to EGFR mediators. Among routine biological parameters, normal leukocytosis and normal neutrophil count, lactate dehydrogenase (LDH) level, calcaemia, haemoglobinaemia and albuminaemia have been identified as favourable independent prognostic factors. Although the analysis was retrospectively done on a subgroup of 261 patients (out of the 443 randomised), the results suggest, surprisingly, that the predictive role of RRM1 is present for sensitivity to cisplatin–vinorelbine with better outcomes observed for RRM1-negative patients (better disease control rate, better progression free survival (6.9 months versus 3.9 months; p<0.001), better overall survival (11.6 months versus 7.4 months; p = 0.002) [63]. The signature proposed by Zhu et al. PubMed. Advances in Lung Cancer, 7, 21-31. doi: 10.4236/alc.2018.73003. Despite recent improvements in its treatment, the prognosis for lung cancer patients remains poor.

[37] derived a five-gene signature with impressive hazard ratio between low- and high-risk patients: 3.36 for overall survival (95% CI 1.35–8.35; p = 0.009) in the validation series (n = 86). PNI was a good biomarker for the assessment of SCLC prognosis for its easy access, convenience to be calculated, and low consumption. This study was devoted to identify glycolysis related genes as prognostic biomarkers for non-small cell lung cancer (NSCLC). People with a higher performance status have a better prognosis than people with a lower performance status score. Vascular endothelial growth factor receptors: VEGF and VEGFR-2 were investigated as predictive biomarkers in the BATTLE study (Biomarker-Integrated Approaches of Targeted Therapy for Lung Cancer Elimination).

Lung cancer is a leading cause of cancer-related death, and >80% of lung cancer diagnoses are non-small-cell lung cancer (NSCLC). For example, genetic signatures that might be very promising are not necessarily validated when adjusted for known classical prognostic factors. Br J Cancer 61:597–604 PubMed Google Scholar. This specific target is expected to be a predictive factor.
