RESUMEN
BACKGROUND: Patients receiving radiotherapy and chemotherapy have a high risk developing to an acute chemoradiotherapy-induced diarrhea (RID). The clinical efficacy of octreotide in controlling chemoradiotherapy-induced diarrhea remains controversial. We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of octreotide for treatment the chemoradiotherapy-induced diarrhoea. METHODS: Relevant RCTs studies assessing the effect of octreotide on clinical outcomes compared with placebo were searched in Cochrane Library, PubMed, EMBASE and Web of Science (up to December 2018). Heterogeneity was assessed with I2, and publication bias was evaluated using sensitive analysis. RESULTS: Eight trials, a total of 594 participants. We found octreotide was significantly effective compared with the control group (OR =3.17; 95% CI, 1.28-7.85; P<0.0001). The overall effect of octreotide was 62.5% (220/352), while that of the control group was 49.3% (168/341). We found octreotide group was effective compared with the control group in 24, 48, and 96 h (OR =16.02; 95% CI, 3.51-73.15; P=0.0003), (OR =4.70; 95% CI, 1.65-13.42; P=0.004) and (OR =14.49; 95% CI, 6.24-33.65; P<0.00001). CONCLUSIONS: Octreotide is superior to conventional therapy in the duration and effectiveness for chemoradiotherapy-induced diarrhea.
RESUMEN
Familial adenomatous polyposis (FAP) is a rare autosomal dominant genetic disease related to germline mutations of the APC gene. The clinical features of this disease most commonly include hundreds of adenomas or polyps. If not treated in a timely fashion, FAP can eventually result in colorectal carcinoma. In this report, clinical manifestations, family history, relevant auxiliary examinations and gene detection from patient blood led us to discover a novel frameshift mutation in exon 12 of the APC gene. The deletion of adenine in c.1439 resulted in the formation of codon 480. The occurrence of this frameshift deletion may lead to inexpressibility of the main functional regions in APC and may affect gene function. In addition, colonoscopy and histopathology showed malignant changes in the colon and rectum. There have been no reports of this frameshift mutation, but it can be considered in case of APC mutations and FAP in patients with clinical manifestations; auxiliary examination may be related, and it may be used as a reference for preventive clinical treatment in the future.
