In each of three randomised phase-III studies, a treatment interaction effect with histology has been identified [42]. 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). Quality of life in lung cancer patients: as an important prognostic factor. Early stages of lung cancer (stages 0 and 1) have a better prognosis than later stages (stages 2, 3 or 4). Tyrosine-kinase inhibitors (TKI) targeting EGFR, such as gefitinib and erlotinib, have been first tested in randomised clinical trials without patient selection in addition to chemotherapy, in chemotherapy-naïve or untreated patients [43–45]. 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]. Early stages of lung cancer have a better prognosis than later stages. There are 2 different pathological types of lung … 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. Enter multiple addresses on separate lines or separate them with commas. Alternatively, restrictive procedures may be not enough. 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. Despite recent improvements in its treatment, the prognosis for lung cancer patients remains poor.

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. In the validation series, the four groups had respective median survival times of 19, 11, 7 and 6 months [41]. dei Colli, Hosp. The stage of lung cancer is the most important prognostic factor. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Prognostic and predictive factors are often discussed together. They both play a part in deciding on a treatment plan and a prognosis. Integrating several targets is also a challenge for future research. Circulating tumor cells as a new predictive and prognostic factor in patients with small cell lung cancer . Search for other works by this author on: Oxford Academic. 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. A clinicopathologic study based on the new International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society international multidisciplinary lung adenocarcinoma classification, The Insternational Association for the Study of Lung Cancer Staging Project. If validated, they could serve as standard covariate for adjustment in the search of further clinically useful factors. 2. They failed to show any benefit of the TKIs, although some clinical factors were suggested to be predictive of benefit: Asian, female sex, non-smoking status, non-squamous histology. The signature proposed by Zhu et al. a design in which only patients harbouring the predictive characteristic are eligible for the trial) have undoubtedly proven that patients with EGFR mutation benefit from TKIs in terms of progression-free survival although the benefit on overall survival is less clear. 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.
