| Abstract: | Background: Most patients with resectable gastric cancer present with locally advanced disease and warrant neoadjuvant chemotherapy based on level 1 evidence. However, the incremental benefit of adding radiation to chemotherapy as a neoadjuvant treatment strategy for these patients is less clear. Methods: While awaiting the results of two ongoing randomized clinical trials attempting to specifically address this question (TOPGEAR and CRITICS-II), this article presents the debate between two gastric cancer surgery experts supporting each side of the argument on the use or omission of neoadjuvant radiation in this setting. Results: On the one hand, neoadjuvant radiation may be better tolerated compared with modern triplet chemotherapy and may be associated with higher rates of major pathologic response. Additionally, there is evidence to suggest that radiation may offer a survival benefit when the tumor is located at the gastroesophageal junction or there is concern for a margin-positive resection. However, in the setting of adequate surgery, no survival benefit has been demonstrated by adding radiation to modern chemotherapy, likely reflecting the fact that death from gastric cancer is a result of distant recurrence, which is not addressed by local treatment such as radiotherapy. Conclusion: While awaiting the results of the TOPGEAR and CRITICS-II trials, this discussion of current evidence can facilitate the refinement of an optimal neoadjuvant therapy strategy in patients with resectable gastric cancer. © 2023, Society of Surgical Oncology. |
