Whether sarcopenia has any impact on long-term survival of patients with surgically treated non-small cell lung cancer (NSCLC) remains unclear. We conducted a meta-analysis focusing on current topic comprehensively for the first time. ⋯ Patients with sarcopenia had a significantly worse prognosis than those without after surgical resection of NSCLC especially in those at early stage. Sarcopenia is an independent unfavorable prognostic factor for patients with surgically treated NSCLC. (246 words).

In the absence of randomized trials, uncertainty regarding the oncologic efficacy of minimally invasive distal pancreatectomy (MIDP) remains. This systematic review aimed to compare oncologic outcomes after MIDP (laparoscopic or robot-assisted) and open distal pancreatectomy (ODP) in patients with pancreatic ductal adenocarcinoma (PDAC). Matched and non-matched studies were included. ⋯ Patients undergoing MIDP were more likely to have smaller tumors (WMD -0.46 cm; 95%CI -0.67 to -0.24; p < 0.001), less perineural (OR 0.48; 95%CI 0.33 to 0.70; p < 0.001) and less lymphovascular invasion (OR 0.53; 95%CI 0.38 to 0.74; p < 0.001) reflecting earlier staged disease as a result of treatment allocation bias. Based on these results we can conclude that in patients with PDAC, MIDP is associated with comparable survival, R0 resection, and use of adjuvant chemotherapy, but a lower lymph node yield, as compared to ODP. Due to treatment allocation bias and lower lymph node yield the oncologic efficacy of MIDP remains uncertain.
