RESUMO

This systematic review and meta-analysis of randomized controlled trials tested the effects of home-based, supervised, or mixed exercise interventions on the functional capacity (FC) and quality of life (QoL) in colorectal cancer patients. A literature search was performed using the PubMed, Embase, Cochrane, and Medline databases. Two reviewers screened the literature through March 10, 2021 for studies related to exercise and colorectal cancer. Of the 1161 screened studies in the initial search, 13 studies met the eligibility criteria (home-based = 6 studies; supervised or mixed = 7 studies). Overall, 706 patients were enrolled in the trials, and 372 patients were submitted to home-based, supervised, or mixed exercise intervention. The overall results from the main meta-analysis showed a significant effect regarding supervised or mixed intervention (6 studies; p = 0.002; I2 = 43%; PI 0.41-1.39); however, no significant effect was observed for home-based intervention (5 studies; p = 0.05; I2 = 25%; PI - 0.34-0.76). A sensitivity analysis based on studies with intervention adherence ≥ 80% (home-based = 3 studies; supervised or mixed = 4 studies) revealed that home-based intervention or intervention entirely supervised or with some level of supervision (mixed) are effective in improving the QoL and FC of CRC patients. In summary, this meta-analysis verified that supervised and home-based exercise can modify QoL and FC when intervention adherence ≥ 80%. Regardless of the supervision characteristics, future RCTs are strongly encouraged to provide a detailed description of the exercise variables in physical interventions for CRC prescription. This perspective will allow a refined exercise prescription for patients with CRC, mainly according to their clinical status.

RESUMO

BACKGROUND: Colorectal cancer decrease quality of life, due to treatment and disease, and physical exercise can improve the quality of life of patients with cancer, but it is still uncertain whether physical exercise can improve quality of life in these patients. AIM: To determine if there is an improvement in the quality of life in patients diagnosed with colorectal cancer undergoing physical exercise. METHODS: A systematic literature review was carried out; non-randomized clinical trials of any year were included from PubMed, Embase, Cochrane, and VHL platforms, without specific language delimitation, and analyzed the influence of physical exercise on the quality of life of patients diagnosed with colorectal cancer, and for analysis of bias, the Cochrane Manual for the Development of Systematic Intervention Reviews was used. RESULTS: Four studies were analyzed in full to produce the results; of these, three intervened with unsupervised aerobic exercises and one with semi-supervised aerobic exercises, all used the FACT-C as a questionnaire to assess quality of life, some even used FACT-G and/or SF-12, and only one author found significance values in the variables of physical well-being, emotional well-being, and functional well-being of the questionnaire, compared with the control group. CONCLUSION: There were no significant increases in the quality of life of patients diagnosed with colorectal cancer compared with the control group.

RESUMO

OBJECTIVE: to characterize patients with ostomy treated at a municipal and regional reference center in the state of Rio Grande do Sul. METHODS: this is a retrospective and descriptive study, based on the records of patients with ileostomy or colostomy recorded in this service between 2000 and 2010. RESULTS: a total of 273 patients were studied, of which 145 were females. The mean age was 64.5 years. Patients with incomplete elementary education (43.6%) and retirees/pensioners (44.7%) were the most prevalent. The main cause for the stoma was neoplastic disease, with 45.8% of colorectal cancer and 5.5% of cancers at other sites. OTHER CAUSES WERE: diverticular disease (7%), bowel obstruction (7%), functional bowel disorders (4.8%), abdominal trauma (2.9%), non-traumatic bowel perforation (2.6%), inflammatory bowel diseases (1.8%) and intestinal polyposis (0.7%). Regarding the type of ostomy, 85.7% were performed by colostomy and 15.8% by ileostomy. CONCLUSIONS: the study population consisted mainly of patients older than 60 and females. The main intervention performed was permanent colostomy and the most important cause for the procedure performance was colorectal cancer. (AU)

OBJETIVO: caracterizar as pessoas com estomia atendidas em um serviço de referência municipal e regional do Rio Grande do Sul. MÉTODOS : estudo retrospectivo e documental, com consulta aos registros dos usuários com ileostomia ou colostomia cadastrados no referido serviço entre 2000 e 2010. RESULTADOS : foram avaliadas 273 pessoas, sendo 145 mulheres e 128 homens. A média de idade foi de 64,5 anos. Prevaleceram usuários com ensino fundamental incompleto (43,6%) e da classe de aposentados/pensionistas (44,7%). A principal causa motivadora da estomia foi a neoplásica, sendo 45,8% de neoplasia de intestino e 5,5% de neoplasias em outros sítios. Outras causas encontradas foram: doença diverticular (7%), obstrução intestinal (7%), transtornos funcionais do intestino (4,8%), traumatismo abdominal (2,9%), perfuração não traumática do intestino (2,6%), doenças intestinais inflamatórias (1,8%) e polipose intestinal (0,7%). Quanto ao tipo de estomia, 85,7% eram usuários de colostomias, e 15,8% de ileostomia. CONCLUSÕES : a clientela do serviço estudado foi composta principalmente por pessoas acima dos 60 anos de idade e por mulheres. A principal intervenção apresentada foi a colostomia permanente e a mais importante causa motivadora da realização do procedimento foi a neoplasia colorretal. (AU)

RESUMO

INTRODUCTION: The EORTC Quality of Life (QL) Group has developed a questionnaire -the EORTC QLQ-CR29- for evaluating QL in colorectal cancer. The aim of this study is to assess the psychometric properties of the EORTC QLQCR29 when applied to a sample of Spanish patients. MATERIALS AND METHODS: Eighty-four locally advanced rectal cancer patients in the treatment follow-up period after receiving surgery and neoadjuvant chemoradiotherapy were included in the study. Seventy subjects also had adjuvant chemotherapy. Patients completed both the EORTC QLQC30 and the QLQ-CR29 once. The psychometric evaluation of the questionnaire's structure, reliability, and convergent, divergent and known-groups validity was performed. RESULTS: Multitrait scaling analysis showed that three of the multi-item scales met the standards of convergent and discriminant validity. These same scales reached the 0.7 Cronbach's coefficient criterion or were close to it. In both analyses exceptions were observed in the blood and mucus in stool scale. Correlations between the scales of the QLQC30 and the module were low (r<0.02) in most cases. A few areas with more related content had higher correlations (r<0.05). Group comparison analyses showed differences in QL between groups of patients based on age, comorbidity, performance status, receipt of adjuvant chemotherapy and surgery modality. CONCLUSIONS: The EORTC QLQ-CR29 is a reliable and valid instrument when applied to a sample of Spanish rectal cancer patients. These results are in line with those of the EORTC validation study.
