Objective: This retrospective study aimed to address the therapeutic outcome for scirrhous gastric cancer patients by evaluating the effect of neoadjuvant chemotherapy prior to gastrectomy.
Methods: Two cycles of a 3-week regimen of fluoropyrimidine S-1 (40 mg/m(2), orally, twice daily), together with cisplatin (60 mg/m(2), intravenously, day 8), were administered to patients, separated by a 2-week rest period. Surgery was performed 3 weeks later in the neoadjuvant group (n = 27). We retrospectively evaluated overall survival and prognostic factors in these patients.
Results: Univariate analysis showed that positive lavage cytology indicated significantly worse prognoses. In the 15 patients who also underwent curative gastrectomies after S-1 plus cisplatin chemotherapy, the pathological response grade was a significant prognostic factor for 5-year survival. Additionally, lymph node metastasis tended to be an adverse prognostic factor.
Conclusion: After S-1 plus cisplatin neoadjuvant chemotherapy, a grade 2-3 pathological response may predict favorable outcomes in scirrhous gastric cancer patients receiving curative gastrectomy, but further studies are needed to confirm these results.
