Background: Despite the continued improvement in the surgical techniques during primary total knee arthroplasty (TKA), literatures indicate that up to 10 to 20% patients are not satisfied with their outcomes. Psychological factors in this dissatisfaction are yet to be clearly identified. The aim of this study is to develop a method to assess whether the patient's current mental state is suitable enough to accept a TKA surgery. Methods: Preoperative demographic and clinical data of 532 patients who underwent TKA were prospectively obtained from January 2012 until December 2016. We recorded the scores evaluated by SF-36 questionnaire and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) preoperatively and 1 year postoperatively. Preoperative Life Satisfaction Rating (LSR) is emphatically evaluated. Results: Poor preoperative score of LSR was a significant predictor of dissatisfaction after TKA. Patients with low LSR reported significant pain and stiffness, although there was no remarkable effect on functionality of the replaced joint. The results also showed that age and BMI were not strong predictors of satisfaction in TKA. Conclusion: Our outcomes can help clinicians evaluate whether a patient's current mental status is favorable for TKA. If patients have extreme low scores of LSR (less than 10), a psychological intervention should be recommended for better satisfaction following a TKA surgery. This would also allow surgeons to individually assess the risks and benefits of surgery. [ABSTRACT FROM AUTHOR]

Background: Glioblastoma (GBM) is one of the worst cancers with bad prognosis despite systemic chemotherapy and radiotherapy after surgery.Methods: In this study, 71 patients with GBM were enrolled and randomly assigned to two groups: Receiving radiotherapy with concomitant and adjuvant temozolomide (TMZ) (TMZ, standard therapy) after surgery, or receiving radiotherapy with concomitant and adjuvant local delivery of nimustine (ACNU) rendezvousing with oral TMZ (rendezvous therapy). In the follow-up of all patients and the progression-free survival (PFS), overall survival (OS), Karnofsky performance score (KPS) and toxicities were recorded.Results: For the whole cohort, the median OS was 18.0 months, and the median PFS was 7.8 months. A significantly longer OS was observed in patients received rendezvous therapy than those who receiving standard therapy (18.5 months vs. 16.0 months; P = 0.014), as well as PFS (8.8 months vs. 7.0 months; P = 0.008). The KPS ≥70 rates were 81.8%, 40.9%, 20.5% in 1, 2, and 3 years for the rendezvous therapy group, significantly superior to standard therapy group. The most common toxicities were tolerable gastrointestinal reaction, liver dysfunction, and hematological toxicities, which were relieved with symptomatic treatment. Grade 3 or 4 toxicity was documented in 8 (18.3%) patients in rendezvous therapy group, while it was observed in 6 (22.2%) patients in standard therapy group during whole treatment process.Conclusions: Compared to standard therapy, the antitumor effects of rendezvous therapy were more effective in GBM patients without increasing the toxicities.

Objective. To establish and validate a nomogram to predict the overall survival (OS) and cancer-specific survival (CSS) in patients with nasopharyngeal carcinoma (NPC) receiving radiotherapy by integrating multiple independent prognostic factors. Materials and Methods. Data from 5663 patients with NPC who received definite radiotherapy between 2004 and 2018 were included and divided into training and validation cohorts. Univariate and multivariate Cox regression analyses were performed to determine the independent prognostic factors of patients with NPC after radiotherapy. Thereafter, the predictive accuracy of the nomogram model was evaluated. Results. Age, race, marital status, pathological type, tumor size, T stage, N stage, M stage, American Joint Committee on Cancer stage, and chemotherapy were independent factors affecting the prognosis of patients with NPC receiving radiotherapy. Nomograms with a concordance index of 0.726 (95% confidence interval (CI): 0.675–0.777) and 0.732 (95% CI: 0.680–0.785) were able to predict OS and CSS, respectively. The area under the curve showed excellent predictive performance. Additionally, the calibration curve indicated that the predicted survival rate was consistent with the actual survival rate, and the decision curve indicated its clinical value. The established risk stratification system was able to accurately stratify patients receiving radiotherapy for NPC into three risk subgroups with significant differences in prognosis (P < 0.05). Conclusions. The constructed nomogram had good prognostic performance and could be used as an effective tool to evaluate the prognosis of patients with NPC after radiotherapy. This nomogram could be further used to guide clinical decisions and personalized treatment plans. [ABSTRACT FROM AUTHOR]
