Background/Aims:
To clarify the efficacy of therapeutic continuous hyperthermic peritoneal perfusion in peritoneal carcinomatosis of gastric cancer.
Methodology:
The subjects of this study were 73 advanced gastric cancer patients who underwent palliative surgery between 1992 and 1999. Therapeutic continuous hyperthermic peritoneal perfusion (T-CHPP) was performed in 21 patients, who had macroscopic peritoneal carcinomatosis or positive lavage cytology, were under 65 years old, had no concomitant disease, and gave informed consent. Fifty-two patients who did not meet the inclusion criteria formed the control group. After reconstruction of the alimentary tract, T-CHPP was carried out for 40 min with 300 mg of Cisplatin, 30 mg of mitomycin C, and 300 mg of etoposide in 5-6 L of physiological saline maintained at 42 degrees C to 43 degrees C.
Results:
The survival of patients who had CY1, P1, P2, P3 was not affected by T-CHPP. Univariate analysis revealed that the degree of peritoneal carcinomatosis and adjuvant chemotherapy were prognostic factors. Furthermore, ill-defined macroscopic appearance and P3 independently affected prognosis, according to multivariate analysis. Patients treated by T-CHPP had higher incidences of respiratory failure (76.2% vs. 17.3%; p < 0.0001) and renal failure (14.3% vs. 0%; p < 0.0054) than those undergoing T-CHPP.
Conclusions:
As T-CHPP had no efficacy, a new therapeutic strategy such as chemosensitivity assessment or a well-structured randomized controlled trial is necessary to obtain good therapeutic results with T-CHPP.
