The classification of bronchogenic carcinoma as a function of the prognosis is still an open field. The evaluation of stage, by use of the TNM system, and histologic cell type is not sufficient to guarantee a correct prognosis. The growth rate of the neoplasm is another important parameter. We propose a classification that takes into account the stage (S), histologic cell type (M), immune status (I) and the growth rate of the primary tumor (G): S.M.I.G. We studied 90 lung cancer patients according to the S.M.I.G. classification and we observed that their prognoses were directly correlated with their S.M.I.G. scores (the higher the score, the higher the 10-month mortality rate). The mortality rates within the first 10 months of follow-up were respectively 0%, 0%, 36.36%, 68%, 90.9% for the 5 groups obtained by S.M.I.G. The difference is statistically significant (P < 0.0075) and there is a linear correlation between the mortality rate and the score assigned to each group (R = 0.943; P < 0.05). The S.M.I.G. classification can predict the prognosis more efficiently than the usual classification (TNM) and histological cell type.

Abstract Introduction Among malignant diseases, lung carcinoma is the most common cancer in men worldwide in terms of both incidence and mortality. Its increasing incidence in developing countries like India is an important public health problem. This work aimed to study the demographic, clinical, radiological, and histological features of patients with confirmed lung cancer. Materials and Methods A total of 50 patients with histologically confirmed lung cancer at a tertiary care center in India from August 2016 to September 2018 were studied and analyzed. Results Out of 50 diagnosed lung cancer patients, 86% were men and 14% women; 31 (62%) patients were aged more than 60 years. Majority were smokers (84%) and all were men. Cough (94%) was the most common presenting symptom followed by dyspnea (68%), chest pain (48%), and hemoptysis (38%). Of the 50 patients, 29 (58%) had soft tissue density mass lesion on radiograph. Squamous cell carcinoma (SCC) was the diagnosed histological cell type in 24 (48%) patients and adenocarcinoma in 21 (42%) patients. Distant metastasis was observed in 20 (40%) patients. Conclusion In this study, the most common histopathological cell type is SCC. Patients aged more than 50 years and smokers are at high risk of lung cancer. Patients with a smoking history and persistent respiratory symptoms should be promptly evaluated for lung malignancy.

The use of circulating cell-free tumour DNA (ctDNA) is established in metastatic lung adenocarcinoma to detect and monitor sensitising EGFR mutations. In early-stage disease, there is very little data supporting its role as a potential biomarker. We report on a prospective cohort of 9 limited-stage EGFR mutant lung cancer patients who were treated with radical radiotherapy. We looked at baseline plasma EGFR ctDNA and noted the detection rates to be higher in locally advanced disease. At a median follow-up of 13.5 months, an association between a detectable pre-radiotherapy plasma EGFR ctDNA and early tumour relapse (155 days vs. NR, p = 0.004) was noted. One patient with persistent plasma EGFR ctDNA predated radiological progression. The role of ctDNA in early-stage lung cancer is developing. Plasma EGFR ctDNA could be a useful biomarker in lung cancer patients undergoing radical treatments for staging, prognostication, and follow-up. These preliminary findings should be explored in larger studies.

18613 Background: Anorexia is a common and major problem in cancer patients. Its ethiology is multifactorial and has negative effects on pts QoL. Up to 30% of non-metastasic lung cancer pts receiving radiotherapy will develop anorexia during treatment. We conducted a randomized trial comparing the efficacy of two different doses of MA. The results of the first 130 pts included, presented at ASCO 2003, indicated that MA at doses of 600 mg/day is significantly more effective in the treatment of anorexia in these pts than low doses (320 mg/day) of MA. Here we present the results of the quality of life sub-study which purpose is to evaluate the effect of reversing anorexia in pts health related quality of life (HRQOL). Methods: From February 1999 to April 2003, 160 non-mestastatic lung cancer pts who developed anorexia during radiotherapy were randomized to receive either 320 mg/day or 600 mg/day of MA. All pts who developed anorexia filled up the EuroQuol (EQ-5D) quality of life questionnaire before treated with MA and the responders did it again when appetite was regained. The endpoint was improvement in pts HRQOL (defined as an increase > 5 mm in the EQVAS score between the second and first questionnaires). Results: The analysis of the EuroQuol (EQ-5D) questionnaires of the 131 pts who responded to treatment with MA shows that 106 pts (81%) had an improvement > 5 mm in the EQVAS score while 19 % did not. The difference is statistically significant (Binomial test: p < 0.0001). Regarding differences between the two series, 42 pts improved in the 320 mg arm versus 64 in the 600 mg arm which is not statistically significant (Fisher test: p = 0.501). Conclusions: Our results indicate that reversal of anorexia with MA has a clinically significant improvement in HRQOL in non-metastatic lung cancer pts undergoing radiation therapy. The absence of statistically significant differences between the two series may be due to the sample size. [Table: see text] No significant financial relationships to disclose.
