El cáncer gástrico remanente (CGR) surge en el estómago residual tras una cirugía gástrica previa. Cuando se identifica en una etapa temprana o superficial, el manejo se centra en lograr un control local definitivo de la lesión en el órgano remanente, potencialmente sin necesidad de reoperación radical.
El éxito se define por lograr la resección macroscópica completa de la lesión sin infiltración linfovascular observada en el examen patológico, criterios que pueden permitir evitar una intervención quirúrgica adicional en pacientes seleccionados.

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.
