Objective To investigate the safety and feasibility of laparoscopic total/subtotal proctocolectomy. Methods Laparoscopic total/subtotal proctocolectomy was performed in 8 cases from March 2003 to November 2005, including 1 case of multiple colorectal tumors, 3 cases of ulcerative colitis, 2 cases of familial adenomatous polyposis, and 2 cases of slow transit constipation. The operation included ileal pouch-anal canal anastomosis in 3 cases, ileal pouch-rectum anastomosis in 3 cases, and cecum-rectum anastomsis in 2 cases. A prophylactic ileostomy was conducted in 5 cases. Results The operation was laparoscopically conducted in all the 8 cases, without conversions to open surgery. No fatal case was encountered. The operative time was 5.5~7.5 h (median, 6 h). The intraoperative blood loss was 150~400 ml (median, 200 ml). There was no intra- or post-operative blood transfusion. The patients began to take diet at 48 h postoperatively. Follow-up observations in 8 cases for 4~31 months (median, 25 months) showed 1 case of intraabdominal infection and 1 case of anastomsis stenosis. Conclusions Laparoscopic total/subtotal proctocolectomy is safe and feasible.

Background and purpose: High-dose chemotherapy followed by autologous stem cell transplantation (auto-HSCT) is considered as the ifrst line treatment for patients with relapse/refractory lymphoma after conventional chemotherapy. However, most of these patients still relapse the second time. The purpose of this study was to analyze the efifcacy of the consolidation chemotherapy after autologous stem cell transplantation (HSCT) refractory/relapse lymphoma in high risk. Methods:A total of 38 patients with relapsed/refractory lymphoma including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were included, who were underwent auto-HSCT in our transplan-tation department from Jan. 2010 to Dec. 2013. In treatment group, 19 patients received 2 courses of consolidation che-motherapy after auto-HSCT every 2 to 3 months, with the regimen of mini-BEAM or modiifed mini-CBV. Another 19 patients had no chemotherapy after auto-HSCT as control group. Results:The median follow-up duration was 17.2 and 7.5 months in the treatment and control group respectively. The follow-up data demonstrated prolonged progression-free survival (PFS) in the treatment group than the control group [24.7 months vs 7.8 months, P=0.029 under intend-to-treat analysis ITT;24.7 months vs 5.2 months, P=0.01 under per protocol analysis(pp)]. There is also a trend of improved overall survival (OS) in the treatment group (P=0.055, ITT). Conclusion:Consolidation chemotherapy after auto-HSCT for refractory/relapsed lymphoma patients delay the relapse and tend to improve the overall relapse rate.

Objective A retrospective analysis of patients with T-cell lymphoma (TCL) received autologous peripheral blood stem cell transplantation (APBSCT) was performed to evaluate the outcome of APBSCT.Methods A total of 22 patients who underwent APBSCT from September 2006 to December 2011 in Ruijin hospital were enrolled in the study,including 6 cases of lymphoblastic lymphoma and 16 of peripheral T-cell lymphoma (8 anaplastic large cell lymphoma, 4 PTCL-u, 1 subcutaneous panniculitis-like T-cell lymphoma, 2 nasal type extranodal NK/T and 1 primary cutaneous T-cell lymphoma). All patients were diagnosed based on the WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues. Conditioning regimens were high-dose chemotherapies alone which include 13 cases with BEAM, 4 with ICE and 5 with CBV. The outcomes of the treatment were evaluated according to the revised International Working Group criteria.Results With a median follow-up of 13.1(1-60) months,the predicted 2-year overall survival (OS) and progression-free survival (PFS) after transplantation were (67.6±11.0) % and (71.1±11.1) %,respectively.A total of 6 patients experienced disease progression and 5 patients eventually died of disease. When all these patients based on the remission status before APBSCT (CR1 vs non-CR1) and chemosensitivity (sensitive vs refractory) were further classified, the PFS rates and OS rates were 100 % and 91.7 % respectively in CR1 or chemosensitive patients which were significantly higher than patients not in CR1 (42.6 % ) or with chemoresistant disease (19.0 % ). Conclusion Remission status and chemosensitivity at the time of transplantation significantly affect the outcome of APBSCT for TCL patients, thus it can be recommend to perform APBSCT for patients either in CR1 or early stage when the disease remain sensitive to chemotherapy.
