Intraoperative and Postoperative Outcomes of Minimally Invasive Versus Open Distal Pancreatectomy for Pancreatic Ductal Adenocarcinoma: A Systematic Review and Meta-Analysis.

Background: This systematic review and meta-analysis compared the intraoperative and postoperative outcomes of minimally invasive versus open distal pancreatectomy (ODP) in patients with pancreatic ductal adenocarcinoma (PDAC), which is a highly aggressive tumor with a high mortality rate. Surgical resection remains the only potentially curative treatment. Minimally invasive distal pancreatectomy (MIDP), including laparoscopic and robotic approaches, has gained popularity, although the evidence of its efficacy is limited.

Prognostic Significance of Circulating Tumor DNA Mutations in Gastrointestinal Stromal Tumors: A Systematic Review and Meta-analysis Based on Time-To-Event Data.

Background: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms of the digestive tract, most commonly originating in the stomach or small intestine, and driven by activating mutations in the KIT or PDGFRA genes. Liquid biopsy has emerged as a promising, minimally invasive technique to detect and monitor circulating tumor DNA (ctDNA), offering real-time insights into tumor dynamics and treatment response. Specifically, detecting KIT/PDGFRA mutations in ctDNA may aid in assessing prognosis, therapeutic response, and resistance.
