RESUMO
BACKGROUND: Colorectal carcinoma (CRC) is widely treated by chemotherapy based on an intensely neurotoxic drug: oxaliplatin (OXL). We objective to evaluate prospectively the orofacial neurotoxicity during FLOX (fluorouracil + leucovorin + OXL) chemotherapy. METHODS: So, 46 patients with CRC were prospectively evaluated during FLOX chemotherapy by 3 cycles (C) of 6 weeks (W) each. We weekly applied the orofacial section of the Acute and Chronic Neuropathy Questionnaire of Common Toxicity Criteria for Adverse Events of the National Cancer Institute of the United States of America (Oxaliplatin-specific neurotoxicity scale). Patients were asked the following concerning the severity (scores 0-5) of orofacial symptoms: jaw pain, eyelids drooping, throat discomfort, ear pain, tingling in mouth, difficulty with speech, burning or discomfort of the eyes, loss of any vision, feeling shock/pain down back and problems breathing. We summed the scores (0-50) and evaluated the clinicopathological data. Friedman/Dunn, Chi square and multinomial regression logistic tests were used (SPSS 20.0, p < 0.05). RESULTS: There was a significant increase in sum of orofacial neurotoxicity from baseline to C1.W3, C2.W1 and C3.W5 (p < 0.001) due increase in scores of jaw pain (p < 0.001), eyelids drooping (p = 0.034), throat discomfort (p < 0.001), ear pain (p = 0.034), tingling in mouth (p = 0.015), burning/discomfort of your eyes (p < 0.001), loss of any vision (p < 0.001), feeling shock/pain down back (p < 0.001), problems with breathing (p = 0.045), but not difficulty with speech (p = 0.087). Women (p = 0.021) and young patients (p = 0.027) had significant higher prevalence of orofacial neurotoxicity. CONCLUSIONS: FLOX-related orofacial neurotoxicity begins acutely and remains long term with increased incidence in women and younger patients.

Burnout syndrome is a common occurrence among oncologists. Doctors enrolled in residency programs in clinical oncology are exposed to similar risk factors; however, few data are available in this population. This study assessed the occurrence of burnout and associated factors among first-year residents at Brazilian institutions. The present prospective, multicenter, cohort study was conducted with doctors enrolled in residency programs in clinical oncology at Brazilian institutions affiliated with the public health system. The participants answered a sociodemographic questionnaire, the Maslach Burnout Inventory (MBI), Lipp's Stress Inventory, and the Beck Depression Inventory (BDI), upon admission to the program and 6 and 12 months later. Of 37 eligible residency programs in 2009, 11 (30.6 %) agreed to participate in the study. Fifty-four residents, representing 100 % of new admissions to the participating institutions, were included. Most of the participants met the criteria for severe burnout upon admission to the residency programs (emotional exhaustion in 49.0 % and depersonalization in 64.7 %). The scores on MBI domains emotional exhaustion and depersonalization increased significantly (p < 0.01) during the first year of residency, and the prevalence of burnout increased to 88 % at the end of that first year. The present study found a high prevalence of burnout among doctors enrolled in residency programs in clinical oncology at Brazilian institutions. A large fraction of the participants met the criteria for burnout syndrome upon admission to the program, which suggests that the problem began during the course of the previous residency program in internal medicine.

Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.
