OBJECTIVE We investigated the outcomes of radiotherapy (RT) combined with systemic chemotherapy (CHT) including carboplatin and paclitaxel in patients with locally advanced non-small-cell lung cancer. METHODS This retrospective study included 105 patients. Treatment involved concurrent carboplatin and paclitaxel with RT administered weekly followed by two cycles of consolidation carboplatin and paclitaxel administered triweekly. RESULTS Comorbid disease was present in 46 (48.6%) patients. At least four cycles of CHT in the concurrent phase and both cycles of CHT in the consolidation phase were able to be administered to 92.3% and 45.4% of patients, respectively. The most common type of toxicity in the entire treatment protocol was hematological toxicity (34.8%). The objective response rate was 71.4%. Overall, recurrence was found in 71 (67.6%) patients. The most common type of recurrence was distant metastasis, which occurred in 47 (66.2%) patients. The median progression-free survival was 14 months. The 1, 2, and 3-year progression-free survival rates were 59%, 30%, and 26%, respectively. The median overall survival was 27 months. The 1, 2, and 3-year overall survival rates were 81%, 57%, and 34%, respectively. CONCLUSION The survival outcomes in this study closely match those reported in the literature. This is notable because our study included a higher proportion of patients with additional health conditions and fewer concurrent CHT cycles during RT compared to randomized studies. These findings prompt us to consider what the ideal number of concurrent CHT cycles should be when using modern involved-field RT techniques after accurate disease staging. [ABSTRACT FROM AUTHOR]

OBJECTIVE It is known that cancer patients are more prone to infections than the general population. We aimed to describe the risk factors affecting the survival of cancer patients infected with COVID-19 and clinical findings compared with a large COVID-19 patient population without cancer diagnosis. METHODS The clinical data of 61 cancer and 558 non-patients with COVID-19 infection who applied to the emergency room were compared retrospectively. Risk factors affecting overall survival in cancer patients were analyzed. RESULTS Gender and mean age were comparable in both groups. In the entire cohort, cancer diagnosis was found to be an independent poor prognostic factor (hazard ratio [HR] = 3.09, p<0.001) among other comorbidities. In univariate analysis; lung cancer, activated partial thromboplastin time >32 seconds, INR >1.1, N-terminal-pro-B-type natriuretic peptide (NT-proBNP) >400 pg/ml, C-reactive protein >100 mg/L, and procalcitonin >0.23 ng/mL were determined as prognostic risk factors. Lung cancer (HR=5.277, p=0.012) and NT-proBNP >400 pg/ml (HR=0.139, p=0.021) were determined as independent prognostic risk factors in multivariate analysis. CONCLUSION Cancer patients with COVID-19 infection have poor survival outcomes. Lung cancer diagnosis and elevated NT-proBNP levels were identified as the most crucial prognostic risk factors in cancer patients infected with COVID-19. [ABSTRACT FROM AUTHOR]
