Abstract

Locally advanced gastric cancer (LAGC) with pancreatic head invasion (T4b) carries a poor prognosis despite radical surgery. Herein, we report the effectiveness of neoadjuvant chemotherapy (NAC) in improving the resectability of advanced gastric cancer with pancreatic invasion. A total of 2191 cases of gastric cancer were retrospectively analyzed from 13 institutions within the Hiroshima Surgical Study Group of Clinical Oncology (Hisco) database from 2018 to 2020. Among them, 5 of the 24 patients with Stage cT4b gastric cancer underwent NAC for three-to-eight cycles. Following chemotherapy, three patients underwent total gastrectomy, two patients underwent distal gastrectomy, and no patient underwent pancreaticoduodenectomy (PD). All five patients achieved a chemotherapeutic response of Grade 1b or higher, and only one case showed residual pancreatic invasion on pathology. This study suggests that NAC for Stage T4b LAGC with pancreatic head invasion may have the potential to obviate the need for PD.

期刊介绍： This online-only journal publishes original case reports on all types of cancer. In particular, we welcome not only case reports of educational value in the diagnosis and treatment of cancers, but also reports on molecularly analyzed cancer cases, including gene mutations, gene fusions, gene expression, and changes in copy number, regardless of their known clinical significance. Assessing the molecular analysis of a tumor usually requires a “cancer conference” in which experts from various fields discuss it. Even if the authors and their respective “cancer conference” were unable to determine the clinical significance of molecular changes at the time of submission and publication, their data may provide evidence that will help the scientific community develop precision medicine solutions in the future. We welcome case reports with reviews of the literature on similar cases, as they are more useful and valuable to readers than are reports of rare cases. International Cancer Conference Journal is the official publication of the Japan Society of Clinical Oncology (JSCO). - Presents an online-only collection of original case reports on all types of cancer - In particular, welcomes molecularly analyzed cancer cases - The Official Publication of the Japan Society of Clinical Oncology (JSCO)
