Meta Analysis
Impact of genetic alterations on long-term outcomes in resectable intrahepatic cholangiocarcinoma: meta-analysis.
Intrahepatic cholangiocarcinoma is a public health threat because of its aggressiveness. Its genetic background differs from other biliary cancers. The aim of this study was to investigate the impact of genetic alterations on long-term outcomes. ⋯ Determining the overall prevalence of the most common actionable and undruggable mutations may help to expand target therapy indications in the adjuvant setting. Inconsistent results have been found for some infrequent gene alterations; their rare involvement could potentially bias their prognostic meaning.

Meta Analysis
Chemotherapy switch for localized pancreatic cancer: a systematic review and meta-analysis.
Patients with localized (that is non-metastatic) pancreatic ductal adenocarcinoma with an inadequate response or toxicity to first-line chemotherapy may benefit from chemotherapy switch. The aim was to explore the available data on the use and effect of chemotherapy switch, as reported in the literature. ⋯ One in five patients with localized pancreatic ductal adenocarcinoma underwent chemotherapy switch after an inadequate response or toxicity to first-line chemotherapy. The pooled resection rate after chemotherapy switch was 42% and similar in overall survival compared with first-line chemotherapy only. Three ongoing trials are investigating chemotherapy switch in patients with an inadequate radiological or carbohydrate antigen 19-9 response.
