AI contribution statement: ChatGPT was used in manuscript only for language polishing, typo and grammar checking purposes. On the other hand, the answer letter to the reviewer comments were translated by ChatGPT. Other than these 2 instances, no ai tool was used for data analysis, interpretation, literature review or making adjustments regarding reviewer’s comments. All the images were generated by the corresponding author, using Google Colab, GIMP and Microsoft Powerpoint software tools, not by an AI.
Institutional review board statement: This study was conducted in accordance with the Declaration of Helsinki and approved by the Ethics Committee of Ankara City Hospital (approval E1/3303/2023).

Core Tip
Core Tip: This retrospective cohort study found that the inflammation/nutrition-based combined score was associated with overall survival in patients undergoing curative gastrectomy for gastric adenocarcinoma. When added to tumor-node-metastasis staging, inflammation/nutrition-based combined score may improve prognostic accuracy. The score reflects systemic inflammation and nutritional status, offering complementary information to tumor anatomy. While these findings are promising, they require validation in larger, multicenter studies before clinical application.
