title: [Experimental foundation of using intraoperative endopelvic cisplatin with hyperthermia for rectal cancer].
abstract: Previously, significant increase in survival in locally-advanced rectal cancer as a result of heated intraoperative intraperitoneal chemotherapy was reported. Our study used cisplatin 0.5 mg/ml (0.05 per cent solution) in the culture of pharyngeal epidermoid carcinoma (PEC) cells (HEP-2) and A-549 culture of lung carcinoma cells. The number of viable cells was estimated colorimetrically after 24 and 48 hr incubation. 50%-rise in inhibition of culture growth was assumed to be biologically significant. Forty-eight hours after inoculation, single dose of cisplatin 8 mg/kg was injected in mice bearing transplanted lung carcinoma of Lewis (LLC). That was followed by death of tumor cells. Preheating (45 deg. C, 1 hr) did not influence either the cytostatic or therapeutic effect of cisplatin in vivo.That procedure inhibited tumor growth by 7-8% and the effect did not wear off until day 11 or longer. Survival in LLC-bearing mice rose by 26% which pointed to the advantages offered by heated cytostatic chemotherapy.
