Perspectives of surgery and multimodality treatment in gastric carcinoma.
Surgery still represents the therapy of choice for patients with primary gastric adenocarcinoma. The best survival results can be achieved if a potentially curative (R0) resection can be performed whatever the extent of resection of the primary tumor (total versus subtotal distal gastrectomy). Either procedure should be accompanied by systematic lymph node dissection since lymphadenectomy has relevant diagnostic (i.e. staging) and therapeutic implications (i.e. improved survival in stage II/IIIA disease). Since most gastric carcinomas are diagnosed in advanced tumor stages, the number of patients to be treated curatively by surgery alone remains limited. Multimodality treatment, consisting of chemotherapy and surgery, may be an encouraging alternative strategy. With actual chemotherapy protocols (i.e. 5-FU/doxorubicin/methotrexate, etoposide/doxorubicin/cisplatin) high remission rates in locally advanced irresectable lesions without distant metastases can be induced. Survival in these patients has been significantly improved after chemotherapy and second-look surgery. The effectiveness of these protocols in an adjuvant setting seems a worthwhile study for the future. In addition, immunological and somatic gene therapy may be of therapeutic impact in the next decade.
