Background: Colorectal adenoma is the precursor lesion of colorectal cancer, and diabetes mellitus is associated with an increased risk for colorectal cancer. Aims: To investigate the clinicopathological characteristics of colorectal adenoma in patients with type 2 diabetes mellitus (T2DM) and the risk factors for advanced adenoma. Methods: Seven hundred and eighty T2DM patients who underwent initial colonoscopy from January 2018 to December 2020 at the Second Affiliated Hospital of Zhejiang Chinese Medical University were enrolled retrospectively, including 227 patients with colorectal adenoma and 553 patients without colorectal polyps. Furthermore, 227 non-diabetic patients with colorectal adenoma who were 1:1 matched to T2DM-adenoma group for gender, age, body mass index (BMI) and smoking history were collected for a comparison study. The clinical and pathological characteristics of T2DM patients with colorectal adenoma were analyzed, and the risk factors for advanced adenoma were identified by univariate and multivariate analyses. Results: T2DM patients with colorectal adenoma were older than those without colorectal polyps, and male gender, tobacco smoking, and cholelithiasis/cholecystectomy were more frequently seen in T2DM-adenoma group (all P<0.05). The proportions of multiple adenomas and advanced adenoma in T2DM-adenoma group were greater than those in patients without T2DM (16.7% vs. 10.1%, and 21.6% vs. 14.1%, all P<0.05). Multivariate Logistic regression analysis identified that male gender (OR=1.299, 95% CI: 1.041-1.831, P=0.008), age (OR=1.129, 95% CI: 1.001-1.421, P=0.025), BMI (OR=1.118, 95% CI: 1.022-1.715, P=0.038) and T2DM (OR=1.408, 95% CI: 1.141-1.721, P=0.010) were the independent risk factors for advanced adenoma. Conclusions: Multiple colorectal adenomas and advanced adenoma are more likely to be detected in patients with T2DM. Male gender, age, BMI and T2DM are associated with the risk of advanced adenoma.

OBJECTIVE:
To explore the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of relapsed or refractory peripheral T-cell lymphoma(PTCL).
METHODS:
The clinical data of 6 patients with relapsed or refractory PTCL undergoing allo-HSCT from Sep. 2014 to Sep. 2018 in the department of hematology, aerospace center hospital were retrospectively analyzed. Complications and disease-free survival after HSCT were observed.
RESULTS:
All the patients could well tolerate the conditioning regimen and acquired hematopoietic recon-struction. Following up till December 2018, with a median time of 11.5 months (1-51); acute GVHD developed in 2 cases and chronic GVHD developed in 5 cases, Among 6 cases one case died of viral pheumonia and the other 5 patients remained disease-free survival. The longest disease-free survival time has reached 51 months.
CONCLUSION
allo-HSCT is a safe and effective method for relapsed or refractory peripheral T-cell lymphoma, which can be chosen as salvage treatment method for patients with primary resistance. Optimization of the conditioning regimen may result in better efficacy of allo-HSCT.
