Effectiveness of continuous hyperthermic peritoneal perfusion for the peritoneal dissemination of gastric cancer

We investigated the effectiveness of continuous hyperthermic peritoneal perfusion (CHPP) for the peritoneal dissemination of gastric cancer. A total 124 patients with advanced gastric cancer were enrolled in this study. Prophylactic CHPP (P-CHPP) was performed in 45 patients who had macroscopic serosal invasion without peritoneal dissemination, and 79 patients without CHPP were a control group. Therapeutic CHPP (T-CHPP) was performed in 21 patients with peritoneal dissemination, and 52 patients without CHPP were a control group. There was no significant difference in 5 year survival between patients treated and not treated with P-CHPP. Univariate analysis showed that location of tumor, tumor diameter, and lymph node metastasis influenced prognosis, but there was no prognostic factor in the Cox proportional regression hazard model. There was no significant difference in 5-year survival between patients treated and not treated with T-CHPP. Univariate analysis showed that degree of peritoneal dissemination and adjuvant chemotherapy influenced prognosis, and the Cox proportional regression hazard model showed that the macroscopic types and degree of peritoneal dissemination affected prognosis. In the patients with CHPP, the incidences of respiratory failure and renal failure were each statistically greater than in the patients undergoing CHPP.

Intraperitoneal chemotherapy in gastric cancer patients with peritoneal dissemination

Peritoneal dissemination is one of the non-curative factors in gastric cancer and colon cancer. Although many treatments have been conducted for peritoneal dissemination, no standard chemotherapy has yet been established. For sometime we had used continuous hyperthermic peritoneal perfusion (CHPP)for peritoneal dissemination in gastric cancer and colon cancer. CHPP has a marked survival benefit for scirrhous type gastric cancer patients without liver metastasis. Patients with prophylactic CHPP have significantly better prognoses than those without prophylactic CHPP, and therapeutic CHPP has a survival benefit for gastric cancer patients with slight to moderate peritoneal dissemination (P 1-2). But CHPP has no significant prognostic benefit for gastric cancer patients with severe peritoneal dissemination (P 3). Therefore, a new cancer treatment is needed for those patients. On the other hand, many kinds of anticancer agents, including cisplatin, via intraperitoneal (ip) administration have been tried thus far for peritoneal dissemination therapy. Especially, intraperitoneal taxane anticancer agent is very effective for the treatment and local control of severe peritoneal dissemination in gastric cancer. A phase I/II study of taxane anticancer agents via ip administration should be tried in gastric cancer patients with peritoneal dissemination.     

Efficacy of continuous hyperthermic peritoneal perfusion for the prophylaxis and treatment of peritoneal metastasis of advanced gastric cancer: evaluation by multivariate regression analysis.

Thirty-two patients with advanced gastric cancer underwent continuous hyperthermic peritoneal perfusion (CHPP) combined with surgery: to prevent peritoneal recurrence in 15 patients without peritoneal metastasis (prophylactic CHPP) and to treat 17 patients with peritoneal metastases (therapeutic CHPP). The postoperative outcome was compared with that of control patients treated with surgery alone. Peritoneal recurrence was less frequent (26%) and the 5-year survival rate was significantly higher (39%) in the patients with prophylactic CHPP than in 40 control patients (42 and 17%, respectively). The patients with therapeutic CHPP showed significantly better median survival than did 20 control patients (11 vs. 6 months). Cox multivariate regression analysis revealed that CHPP was an independent prognostic factor in the prophylactic study (hazard ratio = 0.3965), and that the independent prognostic factor in the therapeutic study was not CHPP but complete resection of the peritoneal metastasis. Thus, CHPP has no marked benefit for established peritoneal metastasis. CHPP for the prevention of peritoneal recurrence may have a beneficial effect on long-term survival, but a prospective randomized trial is needed to clarify its prognostic value.
