8.Postoperative treatment of differentiated thyroid carcinoma with intermediate recurrence risk.
Acta Academiae Medicinae Sinicae 2013;35(4):378-381
The three-level recurrence stratification of differentiated thyroid carcinoma (DTC) has attracted wide attention since its introduction in 2009 American Thyroid Association guidelines. Among these three levels, the postoperative treatment of DTC with intermediate recurrence risk is highly controversial. This article summarizes the relevant advances and controversies in this field.

BACKGROUNDBladder recurrent disease is still a challenge in the treatment of upper tract urothelial carcinoma (UTUC). This controlled study aims to investigate the efficacy of early clipping of the distal ureter prior to nephroureterectomy (NU) to prevent bladder recurrence after UTUC.
METHODSPatients with clinical diagnosis of UTUC were subjected to open trans-peritoneal NU and were randomly divided into two groups. One group received modified NU: clipping the distal ureter prior to NU; while the other group underwent traditional standard NU. Subsequent bladder recurrence was the primary endpoint.
RESULTSFrom January 2007 to December 2009, 85 eligible cases were enrolled in this study. Modified NU and standard NU were performed on 42 and 43 patients, respectively. Operation time ((215.73 ± 21.26) minutes vs. (220.19 ± 15.35) minutes), blood loss ((105.15 ± 11.32) ml vs. (110.12 ± 9.07) ml), transfusion event (11.20% vs. 9.78%), and the in-patient time (10.0 days vs 9.5 days) were not significant between the two groups. After a median follow-up of 28 months (5 - 60), six (14.3%) cases who received modified NU had bladder recurrence, which was significantly lower compared with 15 (34.9%) patients from the group that underwent standard NU (P = 0.026). In univariate and multivariate analysis, tumor grade (HR 4.33, 95%CI 2.66 - 6.30, P = 0.01) and operation type (HR 2.35, 95%CI 1.53 - 3.48, P = 0.041) were independent risk factors for subsequent bladder recurrence after UTUC.
CONCLUSIONSClipping the distal ureter at the beginning of NU significantly reduces bladder recurrence after UTUC. It is reasonable to conclude that clipping the distal portion of ureter trans-peritoneal is an effective surgical procedure for the treatment of UTUC.

OBJECTIVE:
To analyze the survival, prognostic factors, and prevention of relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with hematological malignancies, and explore the relationship between immune reconstruction, loss of human leukocyte antigen (HLA-loss) and relapse after transplantation.
METHODS:
From July 2012 to June 2020, 47 patients with hematological malignancies who relapsed after allo-HSCT were retrospectively analyzed, including 20 cases undergoing matched-sibling donor transplantation (MSD), 26 cases undergoing haploidentical transplantation (HID), and 1 case undergoing matched-unrelated donor transplantation (MUD). Multivariate analysis was used to analyze the risk factors related to post-relapse overall survival (PROS).
RESULTS:
All the 47 patients were implanted successfully. The cumulative incidence of grade Ⅱ-Ⅳ, Ⅲ/Ⅳ acute graft-versus-host disease (aGVHD) and chronic GVHD (cGVHD) was 40.4%, 10.6%, and 31.9%, respectively. The incidence of grade Ⅱ-Ⅳ and Ⅲ/Ⅳ aGVHD in HID group was 42.3% and 11.5%, while in MD group was 38.1% and 9.5% (P=0.579, P=1.000), and the incidence of cGVHD in the two groups was 34.6% and 28.6% (P=0.659). The PROS of patients with NK cell absolute count > 190 cells/μl 30 days after transplantation was higher than that of patients with NK cell absolute count ≤190 cells/μl (P=0.021). The 1-year and 3-year PROS of all the patients was 68.1% and 28.4%, respectively, while in the HID group was 78.9% and 40.3%, in the MD group was 54.4% and 14% (P=0.048). Multivariate analysis showed that grade Ⅱ-Ⅳ aGVHD and time of relapse < 3 months were independent risk factors of PROS (P<0.05).
CONCLUSION
The therapeutic effect of haploidentical transplantation in patients with relapsed hematological malignancies after allo-HSCT is better than that of matched donor transplantation. The high absolute count of NK cells 30 days after transplantation can increase PROS. Grade Ⅱ-Ⅳ aGVHD and time of relapse < 3 months have prognostic significance for long-term survival of patients with relapsed hematological malignancies after transplantation.
