[Excretion Management During Colorectal Cancer Chemotherapy]

There are almost no reports about drug excretion management during colorectal cancer chemotherapy. Anticancer chemotherapeutic drugs excreted in urine and feces may exert toxic effects and promote teratogenesis, mutagenesis, and carcinogenesis. To assess the knowledge of patients about drug excretion, a questionnaire survey was performed among 45 patients receiving chemotherapy for colorectal cancer in our hospital; among them, 36 patients completed the survey. Most of the patients did not know about the excretion and toxic effects of anticancer drugs. The results indicate that patients should be instructed on the management ofexcretion during chemotherapy to minimize toxic exposure. We believe that unnecessary exposure of patients and their families to anticancer drugs should be minimized. This study highlights the importance of issuing guidelines regarding excretion management during cancer chemotherapy.
