Does surgery have a role in managing incurable gastric cancer?

Abstract

Stage IV gastric cancer is incurable and has a very poor prognosis. Although palliative chemotherapy remains the standard of care, increasing evidence indicates that palliative surgery can provide a prognostic and symptomatic benefit. This Perspectives summarizes the recent evidence underpinning the medical and surgical management of incurable gastric cancer, and provides evidence-based recommendations on treatment strategies and avenues for future research. Although the incidence of gastric cancer is decreasing, the outcomes of this disease are among the poorest of all solid-organ tumours, predominantly due to the frequent presence of stage IV metastatic disease at primary presentation. Stage IV gastric cancer is incurable and carries a very poor prognosis (5-year survival rate of ∼4%); palliative chemotherapy remains the standard of care, but increasing evidence indicates that palliative surgery can provide a prognostic and symptomatic benefit, particularly in combination with chemotherapy and/or radiotherapy. Ongoing prospective trials should further clarify the efficacy of palliative surgery in comparison with other treatment modalities. Until such data are available, surgery should not be offered as a standard first-line treatment, but can be considered in selected cases after thorough multidisciplinary discussions involving the patient. Patient selection for both gastrectomy and nonresectional surgery must include consideration of various factors that predict quality of life after surgery. This Perspectives summarizes the available evidence and discusses the utility of palliative surgery in relation to other therapeutic modalities in the management of incurable gastric cancer.
