Abstract
Reducing polyamine uptake by selecting low polyamine-containing foodstuffs and reducing bacterial gut production can improve performance status and pain control in hormone refractory prostate cancer (HRPC) patients. Long term PRD observance and tolerance were assessed. Cancer specific survival was studied in function of PRD and time of PRD initiation. Twenty-six volunteers, age: 68+/-10 years with metastatic HRPC accepted a polyamine reduced diet and partial gut decontamination with oral neomycin or nifuroxazide (750 mg daily, one week out of two). Time from HRPC to PRD initiation was 10+/-8 months. WHO performance status, EORTC pain scale, body weight, blood counts and serum proteins were regularly assessed. Sixteen other HRPC patients eating a normal diet served as "controls". Mean diet observance is 25+/-24 months. Tolerance is good. WHO performance status and EORTC pain scales were significantly improved respectively at 3 months (0.5+/-0.7 vs 0.7+/-0.9: p=0.03) and 6 months (0.5+/-0.8 vs 1+/-1.3, p=0.02) compared to initial values. Median cancer specific survival times after HRPC and PRD initiation are respectively 36 and 21 months. Eleven PRD patients started the diet before a 9 months cut-off period (after HRPC) and 15 pa...Continue Reading
