RESUMO
Background: The occurrence of peroneal neuropathy was reported to be higher in cancer patients than in non-cancer patients. Cancer patients should have their nutritional intake carefully managed in order to minimize weight loss and avoid the occurrence of peroneal neuropathy. However, the effect of nutrition support on the prevention of peroneal neuropathy is not understood. Aims: The present study aimed to assess epidemiologically the effect of nutrition support on the occurrence of peroneal neuropathy in cancer patients. Methods: We performed a retrospective case-control study in 178,597 cancer patients admitted to Shizuoka Cancer Center Hospital from 2002 to 2017. The rates of peroneal neuropathy were assessed between the 8-year period before nutrition support started and the 7-year period during which nutrition support performed. Results: Twenty-nine and 14 cases of peroneal neuropathy occurred in the periods without and with nutrition support, respectively. Compared with the period without nutrition support, the risk of peroneal neuropathy decreased by 62% during the period with nutrition support (odds ratio, 0.38; 95% confidence interval, 0.18-0.74; P < 0.05). Conclusion: Our study suggests the preventive effects of nutrition support on peroneal neuropathy in cancer patients.
RESUMO
We retrospectively investigated the frequency and severity of adverse events in 124 patients with colorectal cancer who were treated by mFOLFOX6 regimen from August, 2005 to December, 2006. The incidences of grade 3/4 adverse events were; leucopenia 16%, neutropenia 40%, anemia 11%, thrombocytopenia 7%, febrile neutropenia 7%, nausea 3%, vomiting 2%, anorexia 2%, diarrhea 4%, fatigue 7%, and alopecia 0%. The incidences of all grades and grade 3/4 hypersensitivity reaction were 35% and 4%, and the median number of course when it firstly appeared was 6(range, 1-21). The incidences of all grade and grade 3 peripheral sensory neuropathy were 74% and 6%, and the median number of course when it firstly appeared 11(range, 6-16). The incidences of adverse events in this cohort were similar or lower than those reported in Western countries. Our investigation shows that mFOLFOX6 regimen is tolerable in clinical practice in Japan. The informed consent form was revised based on these results. The incidences of adverse events were renewed to provide useful information and improve self-care ability. The symptoms and the time to appearance of the hypersensitivity reaction and peripheral sensory neuropathy were added. We think it is important to provide the information based on the clinical practice.
