ABSTRACT

ABSTRACT BACKGROUND: Worldwide, colorectal cancer (CRC) and gastric cancer (GC) are the third and the fifth most prevalent, respectively. Diarrhea is a common symptom in patients on chemotherapy or radiotherapy treatment and can reduce treatment tolerance. Surgical resections and chemotherapy change the intestinal microbiota that can lead to lactose intolerance, small intestinal bacterial overgrowth (SIBO). OBJECTIVE: The aim of the study was to evaluate the frequency of diarrhea in patients with CRC and GC on chemotherapy with SIBO or intolerance of lactose. METHODS: This is a descriptive and observational study with patients of both sexes, over 18 years old, in treatment in the Gastro-Oncology outpatient clinic of the Federal University of São Paulo. Patients with a confirmed diagnosis of CRC or GC during chemotherapy treatment were included. To detect bacterial overgrowth and lactose intolerance, breath hydrogen test with lactulose and lactose was done. Number and aspects of the evacuations and toxicity degree were collected. For the nutritional assessment, weight and height were performed to calculate the BMI. and the Patient Generated Subjective Global Assessment (PG-SGA). RESULTS: A total of 33 patients were included, 29 with CRC and 3 with GC. Most of them were male (57.57%), mean age of 60.03±10.01 years and in chemotherapy with fluoropyrimidine and oxaliplatin (54.5%). Diarrhea was present in 57.6% and 30.3% had toxicity grade 2. According to the BMI, 78.9% were eutrophics, obese or overweight, but according to PG-SGA, 84.9% had moderate or severe nutritional risk grade. Between patients, 45% had lactose intolerance and 9% SIBO. Diarrhea grade 2-3 was observed in 66.6% of patients with SIBO and 66.7% of that with lactose intolerance. No statistical difference was observed between patients with SIBO or lactose intolerance and grade of diarrhea. CONCLUSION: Diarrhea was a frequent symptom in chemotherapy patients with gastric or colorectal cancer independent of the presence of SIBO or lactose intolerance. Surgery and chemotherapy treatment impacted in the intestinal habit of patients. Diagnosis of other causes of diarrhea may contribute to a better tolerance to treatment and quality of life.


RESUMO CONTEXTO: Mundialmente, o câncer colorretal (CCR) e gástrico (CG) são a terceira e a quinta causa de câncer mais prevalente, respectivamente. A diarreia é um sintoma comum entre os pacientes em quimioterapia ou radioterapia e pode reduzir a tolerância ao tratamento. Quimioterapia e ressecções cirúrgicas causam alterações da microbiota intestinal que podem levar a intolerância à lactose e ao supercrescimento bacteriano do intestino delgado (SBID). OBJETIVO: Avaliar a presença de diarreia nos pacientes com câncer colorretal e gástrico em quimioterapia e a presença de SBID ou intolerância à lactose. MÉTODOS: Foi realizado um estudo descritivo, observacional com pacientes ambulatoriais de ambos os sexos, maiores de 18 anos, em tratamento no ambulatório de gastro-oncologia da Universidade Federal de São Paulo. Foram incluídos pacientes com diagnóstico confirmado de CCR ou CG durante tratamento quimioterápico. Para detectar supercrescimento bacteriano e intolerância à lactose, foram realizados testes respiratórios com lactulose e lactose respectivamente. Número, aspecto das evacuações e grau de toxicidade foram coletados. Para a avaliação nutricional foram aferidos peso e altura para cálculo do IMC e para avaliação do risco nutricional foi realizada a avaliação subjetiva global produzida pelo próprio paciente (ASG-PPP). RESULTADOS: Foram incluídos 33 pacientes, 29 com CCR e 3 com CG. A maioria era do sexo masculino (57,5%) com média de idade 60,03±10,01 anos e em tratamento quimioterápico com fluoropirimidina e oxaliplatina (54,5%). Diarreia foi relatada por 57,6% dos pacientes sendo em 30% grau 2. Pelo IMC, 78,9% apresentavam eutrofia, sobrepeso ou obesidade grau 1, mas pela ASG-PPP 84,9 apresentavam risco nutricional moderado ou severo. Entre os pacientes 9% apresentavam SBID e 45% intolerância à lactose. Diarreia grau 2-3 foi observada em 66,6% daqueles pacientes com SBID e 66,7% dos com intolerância à lactose. Não encontramos diferenças estatísticas entre os pacientes com SBID ou intolerância à lactose e intensidade de diarreia. CONCLUSÃO: Diarreia foi um sintoma frequente entre os pacientes com câncer gástrico ou colorretal em quimioterapia independente da presença de SBID ou intolerância à lactose. Cirurgia e quimioterapia impactaram no hábito intestinal dos pacientes. O diagnóstico de outras causas de diarreia pode contribuir para a melhor tolerância do tratamento e qualidade de vida.

ABSTRACT

ABSTRACT Objective To investigate the effects of oral zinc supplementation on fatigue intensity and quality of life of patients during chemotherapy for colorectal cancer. Methods A prospective, randomized, double-blinded, placebo-controlled study was conducted with 24 patients on chemotherapy for colorectal adenocarcinoma in a tertiary care public hospital. The study patients received zinc capsules 35mg (Zinc Group, n=10) or placebo (Placebo Group, n=14) orally, twice daily (70mg/day), for 16 weeks, from the immediate postoperative period to the fourth chemotherapy cycle. Approximately 45 days after surgical resection of the tumor, all patients received a chemotherapeutic regimen. Before each of the four cycles of chemotherapy, the Functional Assessment of Chronic Illness Therapy-Fatigue scale was completed. We used a linear mixed model for longitudinal data for statistical analysis. Results The scores of quality of life and fatigue questionnaires were similar between the groups during the chemotherapy cycles. The Placebo Group presented worsening of quality of life and increased fatigue between the first and fourth cycles of chemotherapy, but there were no changes in the scores of quality of life or fatigue in the Zinc Group. Conclusion Zinc supplementation prevented fatigue and maintained quality of life of patients with colorectal cancer on chemotherapy.


RESUMO Objetivo Investigar os efeitos da suplementação oral de zinco sobre a intensidade da fadiga e a qualidade de vida de pacientes durante a quimioterapia para neoplasia colorretal. Métodos Estudo prospectivo, randomizado, controlado e duplo-cego conduzido em um hospital universitário público terciário, com 24 pacientes em regime quimioterápico para adenocarcinoma colorretal. Os pacientes receberam cápsulas de zinco 35mg (Grupo Zinco, n=10) ou placebo (Grupo Placebo, n=14) por via oral, duas vezes ao dia (70mg/dia), durante 16 semanas, desde o período pós-operatório imediato até o quarto ciclo de quimioterapia. Todos os pacientes receberam quimioterapia por aproximadamente 45 dias após a ressecção cirúrgica do tumor. A escala Functional Assessment of Chronic Illness Therapy-Fatigue foi preenchida antes de cada um dos quatro ciclos de quimioterapia. Utilizou-se o modelo de regressão linear misto para dados longitudinais para análise estatística. Resultados Os escores de qualidade de vida e de fadiga foram semelhantes entre os grupos de estudo durante os ciclos de quimioterapia. O Grupo Placebo apresentou piora da qualidade de vida e da fadiga entre o primeiro e o quarto ciclos de quimioterapia, mas não houve mudança nos escores de qualidade de vida e fadiga no Grupo Zinco. Conclusão A suplementação com zinco previne a fadiga e preserva a qualidade de vida de pacientes em quimioterapia para neoplasia colorretal.

ABSTRACT

(0.05)). Multivariate analysis revealed that adjuvant radiotherapy and histology of tumor significantly affected the prognosis(P=(0.045) and P=(0.009), respectively). Whereas loco-regional control was only significantly affected by adjuvant radiotherapy(P=(0.000)). CONCLUSION: Adjuvant radiotherapy and histology of tumor are the important prognostic factors in the rectal cancer patients after treatment with multimodality therapy based on surgery.
