trial (NCT01171170 1), body composition was characterized by CSA and distribution of both muscle and adipose tissue at the third lumbar level on CT-images obtained at baseline and three weeks after start of chemotherapy. Changes in body composition parameters were related to OS with Kaplan Meier and log-rank test. Cox multivariate analysis was performed to assess the relative contribution of muscle and adipose tissue CSA and distribution to OS. Result: Data were available of 103 patients. Cox regression analysis showed that loss of muscle CSA and IMAT independently affected survival while change in SAT and VAT did not. 74 patients (72%) exhibited muscle loss (group 1) versus 29 patients (28%) who had stable or gain of muscle CSA (group 2). Groups were comparable regarding age, WHO PS, TNM status, and Charlson comorbidity index. Median OS (95% CI) was 10.0 (7.9-12.2) months in group 1 and 15.3 (11.1-19.5) months in group 2 (p¼0.004). Among muscle losing patients two subgroups were distinguished based on IMAT change. Loss of muscle mass combined with loss of IMAT (group 1a, n¼33) also showed significant loss of SAT and lower survival rates compared to loss of muscle mass with preserved IMAT (group 1b, n¼40). Median OS (95% CI) was 7.3 (5.0-9.5) months in group 1a compared to 12.9 (9.2-16.6) months (p<0.001) in group 1b. Conclusion: Early changes in body composition patterns during the first cycle of chemotherapy in metastatic NSCLC are predictive for OS and might be useful for more personalized supportive intervention during followup treatment.

Objective: The present study aims to highlight the utility of quantitative polymerase chain reaction (qPCR) as a method for identifying typical and atypical mycobacterial infections in patients with mastitis and granulomatous lymphadenitis. Materials and methods: A total of five patients initially diagnosed with mastitis or granulomatous lymphadenitis based on their clinical characteristics in whom conventional tests were used as a diagnostic method were selected. Conclusion: The present study showed that the routine performance of qPCR for typical and atypical mycobacteria allows for improved diagnosis.
