The optimal adjuvant treatment of high-risk low-grade glioma (LGG) is controversial. We performed this retrospective cohort study to compare three treatments including observation, radiotherapy (RT) alone, and radiotherapy combined with concomitant and adjuvant temozolomide (TMZ) chemotherapy (STUPP regimen) in patients with high-risk LGG. Patients with high-risk (age > 40 or undergoing subtotal resection or biopsy) LGG treated with observation or radiotherapy alone or STUPP regimen after operation were retrospectively analyzed. Survival rates were evaluated by the Kaplan-Meier method; the log-rank test was applied to compare differences between groups. A total of 250 patients met the inclusion criteria. Median follow-up for living people was 70 months. Overall, patients who received radiotherapy with or without temozolomide had better progression-free survival (PFS) and overall survival (OS) when compared with observation (median PFS: observation, 59 months; RT, 82 months; STUPP, not reached; median OS: observation, 96 months; RT, not reached; STUPP, not reached), whereas STUPP regimen did not further prolong PFS or OS than RT alone (PFS, P = 0.203; OS, P = 0.146). In oligodendroglioma (IDH mutant and 1p/19q codeleted) subtype, only STUPP regimen brought longer PFS when compared with observation (P = 0.008). The incidence of grade 3 or 4 neutropenia (P < 0.001) and nausea or vomiting (P = 0.004) was higher in the STUPP group than the figure for the RT alone group. PFS and OS were similarly improved in patients with high-risk LGG receiving RT alone or STUPP regimen. However, only STUPP regimen was able to bring better PFS for oligodendroglioma (IDH mutant and 1p/19q codeleted) subgroup. Longer follow-up time is needed to determine an association with treatment effect in different histological and molecular subgroups.

To investigate the effect of inhibiting transforming growth factor‐β (TGF‐β1)/Smad2/3 signaling on rotator cuff (RC) healing. A bilateral supraspinatus tendon detachment‐repair model of Sprague‐Dawley (SD) rats was utilized. A total of 120 SD rats were randomly assigned to six groups and each group received the subacromial injection of normal saline, empty vectors, or lentiviral vectors containing small interfering RNA against TGF‐β1, Smad2, Smad3 at the bone‐tendon junction. Biomechanical and histological analyses were performed to evaluate bone‐tendon junction healing quality at 8 weeks after repair. Histologically, scar healing was found in all surgical groups. Animals with inhibited Smad3 exhibited better bone‐tendon junction structures with higher density, parallel orientation, and collagen fiber continuity than other surgical group animals. Immunohistochemistry revealed that the protein expression level of collagen I in animals with inhibited Smad3 was more prominent compared with all other surgical groups. Biomechanically, Animals with inhibited Smad3 showed better results in the maximum load at 4, 6, and 8 weeks after surgery compared with other surgical groups. Besides, C3H10T1/2 (Smad3?) cells increased TT‐D6 cell migration and tendon‐associated genes expression (scleraxis, tenascin C, collagen I) in coculture system. We conclude that inhibition of Smad3 promotes RC tendon healing in the rat supraspinatus model. 相似文献
AimsChronic kidney disease (CKD) and diabetes mellitus increase atherosclerotic cardiovascular diseases (ASCVD) risk. However, the association between renal outcome of diabetic kidney disease (DKD) and ASCVD risk is unclear.MethodsThis retrospective study enrolled 218 type 2 diabetic patients with biopsy-proven DKD, and without known cardiovascular diseases. Baseline characteristics were obtained and the 10-year ASCVD risk score was calculated using the Pooled Cohort Equation (PCE). Renal outcome was defined as progression to end-stage renal disease (ESRD). The association between ASCVD risk and renal function and outcome was analyzed with logistic regression and Cox analysis.ResultsAmong all patients, the median 10-year ASCVD risk score was 14.1%. The median of ASCVD risk score in CKD stage 1, 2, 3, and 4 was 10.9%, 12.3%, 16.5%, and 14.8%, respectively (p = 0.268). Compared with patients with lower ASCVD risk (<14.1%), those with higher ASCVD risk had lower eGFR, higher systolic blood pressure, and more severe renal interstitial inflammation. High ASCVD risk (>14.1%) was an independent indicator of renal dysfunction in multivariable-adjusted logistic analysis (OR, 3.997; 95%CI, 1.385–11.530; p = 0.010), though failed to be an independent risk factor for ESRD in patients with DKD in univariate and multivariate Cox analysis.ConclusionsDKD patients even in CKD stage 1 had comparable ASCVD risk score to patients in CKD stage 2, 3, and 4. Higher ASCVD risk indicated severe renal insufficiency, while no prognostic value of ASVCD risk for renal outcome was observed, which implied macroangiopathy and microangiopathy in patients with DKD were related, but relatively independent. 相似文献
BackgroundMultivisceral resection may be the exclusive radical procedure for cT4b gastric cancer patients. However, most surgeons refuse to select surgery because of the theoretical higher mortality, morbidity and poorer prognosis.MethodsWe retrospectively reviewed cT4b gastric cancer patients who underwent surgery from January 1,1997 to December 31,2018. The primary endpoint was overall survival. Short-term results and prognostic values of clinical and pathologic factors were also analyzed.ResultsPatients underwent multivisceral resection had an acceptable mortality and morbidity. The overall 5-year survival rate of multivisceral resection was higher than that of palliative surgery (P < 0.05). And independent prognostic factors of multivisceral resection were R+ resection, extensive lymph node involved (>15), vascular cancer emboli, and postoperative chemotherapy.Conclusions: cT4b gastric cancer patients underwent multivisceral resection experience acceptable mortality and morbidity. The independent prognostic factors for multivisceral resection were completeness of resection, extensive lymph node involvement (>15), vascular cancer emboli, and postoperative chemotherapy. 相似文献
