What is the treatment approach for a gastric tumor situated 5-10 cm from the OG junction?

For a gastric tumor located 5-10 cm from the oesophagogastric (OG) junction, the most appropriate treatment approach is subtotal gastrectomy with lymphadenectomy. This approach is indicated because tumors in this region often necessitate the removal of a significant portion of the stomach to achieve adequate margins and ensure that all malignant tissue is excised.

Subtotal gastrectomy involves the resection of a portion of the stomach while preserving the remaining stomach. This procedure is particularly appropriate for tumors that are not amenable to limited resection methods, such as endoscopic resection, especially given their size and proximity to the OG junction.

Lymphadenectomy is an essential component of this surgical approach, especially in gastric cancers, due to the high incidence of lymphatic spread in this disease. By removing adjacent lymph nodes, the risk of residual disease is reduced, and it provides crucial staging information that can inform further treatment.

This surgical strategy balances the need for oncologic resection with the preservation of gastrointestinal function. While total gastrectomy removes the entire stomach and is sometimes necessary for advanced or diffuse malignancies, it is often not the first-line approach for localized disease at this specific location unless there are specific indications such as multifocal tumors or
