The subjects of this retrospective study were 67 patients who received chemotherapy for type 4 gastric cancer. The patients were grouped into those with progressive disease (PD group) and those without PD (non-PD group), according to the tumor response to chemotherapy. Distant metastases developed in 58 patients. With regard to tumor response, there were 16 patients in the PD group and 51 patients in the non-PD group. The prognosis of the PD group patients was significantly poorer than that of the non-PD group patients (p < 0.0001). R0 resection was performed for 21 of 23 patients who underwent surgery after chemotherapy. Multivariate analysis revealed tumor response and surgery as independent prognostic factors (p = 0.0001 and p = 0.0009, respectively). Moreover, multivariate analysis of the surgery group revealed that metastatic nodal status (N0-1 vs. N2-3) and residual tumor status (R0 vs. R1-2) were significant independent prognostic factors (p = 0.0258 and p = 0.0458, respectively). The findings of this study suggest that surgery after chemotherapy for type 4 gastric cancer may improve the prognosis of responders with N0-1 status, who undergo curative R0 resection. The findings of this study suggest that surgery after chemotherapy for type 4 gastric cancer may improve the prognosis of responders with N0-1 status, who undergo curative R0 resection. This retrospective study was conducted to compare the long-term outcomes of single-incision totally extraperitoneal (S-TEP) inguinal hernia repair and conventional multiport totally extraperitoneal (M-TEP) inguinal hernia repair. The study population included 186 consecutive patients (S-TEP, n = 149; M-TEP, n = 37) who underwent elective surgery for inguinal hernia at Osaka Police Hospital between 2011 and 2013.
