ينشأ سرطان المعدة المتبقية (RGC) في المعدة المتبقية عقب جراحة معدة سابقة. وعند اكتشافه في مرحلة مبكرة أو سطحية، تنصبّ الجهود على تحقيق السيطرة المحلية النهائية على الآفة داخل العضو المتبقي — مع إمكانية تجنب إعادة الجراحة الجذرية.
يُعرَّف النجاح بتحقيق استئصال كامل للآفة على المستوى العياني مع غياب الارتشاح اللمفاوي الوعائي في الفحص المرضي — وهي معايير قد تتيح تجنب التدخل الجراحي الإضافي لدى مرضى مختارين.

Endoscopic resection is first-line therapy in the management of superficial neoplasms throughout the gastrointestinal tract, as well as an increasingly viable therapeutic alternative in the resection of selected small deep lesions throughout the upper and lower gastrointestinal tract.
Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are two well-known endoscopic resection procedures used for advanced gastrointestinal lesions.
In the past, remnant gastric cancer (RGC) was commonly detected at an advanced stage where radical surgical resection was considered the only method for achieving cure. However, completion gastrectomy does not improve survival outcomes compared with endoscopic resection and may even adversely affect the long-term outcomes of patients with early RGC.
Additional surgical resection might be avoided in selected cases that can even present noncurative features after endoscopic resection if macroscopic complete resection is achieved and lymphovascular infiltration is not observed.
