AI Article Synopsis
- A systematic evaluation of postoperative radiotherapy after radical prostatectomy was conducted, analyzing data from randomized controlled trials published before June 2014.
- Five trials involving 2,290 cases were included, revealing that while there was no significant difference in overall survival rates, postoperative radiotherapy improved biochemical progression-free survival.
- The conclusion is that postoperative radiotherapy can enhance biochemical progression-free survival, but it does not impact overall survival rates.
Article Abstract
Objective: A systematic evaluation was carried out over the effectiveness and safety of postoperative radiotherapy following radical prostatectomy.
Method: The randomized controlled trials that were concerned with postoperative radiotherapy for prostatic cancer and published before June 2014 were searched in PubMed, EMBASE, Cochrane Library, CBM, CNKI and VIP databases. Two researchers conducted quality evaluation and data extraction independently for all included literature. Rev Man 5.2 software was used for statistical analysis.
Results: Finally 5 randomized control trials involving 2290 cases were included. Meta-analysis showed that the approaches of radical prostatectomy with or without postoperative radiotherapy did not differ significantly in terms of overall survival (HR=1.09, 95% C1: 0.75-1.60, P=0.65). However, significant difference was found in biochemical progression-free survival (HR=0.54, 95% CI: 0.42-0.69, P < 0.001).
Conclusion: Evidences show that postoperative radiotherapy following radical prostatectomy can increase biochemical progression-free survival but not overall survival.

Objective: The objective of this study was to discuss the characteristics of intracranial extension in patients with juvenile nasopharyngeal angiofibroma (JNA) and propose and an algorithm for its management.
Methods: A retrospective chart review of all patients with JNA who underwent operations between January 2013 and January 2023 was done, and those cases with intracranial extension categorized as stage IIIb, IVa, and IVb according to the Andrews modification of the Fisch staging classification were included in the study. Data were collected about age at presentation, symptoms, radiological findings, routes of intracranial extension, therapeutic management, and follow-up.

For patients with nonmetastatic soft tissue sarcoma (STS) who are at high risk of local recurrence, the standard of care for limb-conserving local management is combined radiotherapy and surgery. Radiotherapy for STS entails 5 weeks of conventionally fractionated radiotherapy (25 × 2 Gy) preoperatively or 6 or more weeks postoperatively. There is growing interest in the use of preoperative hypofractionated regimes, viz.

Breast Surgery Section, Division of GI and Oncologic Surgery, Massachusetts General Hospital, Boston, MA, USA.
Background: Nipple-sparing mastectomy (NSM) is infrequently performed in older women, at least in part owing to concerns regarding age-related complications. We describe postoperative outcomes of NSM in older women and risk factors for complications, with the goal of informing patient selection and decision-making.
Patients And Methods: Cases of NSM with immediate implant-based reconstruction were identified from an institutional database (2009-2019).

Objective: The optimal initial management strategy for cervical cancer with lymph node metastases (LNM) remains a topic of ongoing debate. This study aimed to explore the correlation between surgery followed by postoperative radiotherapy (PORT) and definitive radiotherapy (RT), as well as their impact on the prognosis of patients with LNM.
Methods: Patients with positive lymph nodes (PLNs) in 2009 FIGO stage I-III cervical cancer were selected from SEER database.

The coexistence of intracranial multiple meningiomas and neurofibromatosis type 1 is a rare occurrence in the field of neurosurgery, presenting complex treatment challenges, unfavorable prognoses, and significant burdens on both families and society. Currently, the primary objective is to perform surgical total resection as far as possible, while considering postoperative adjuvant radiotherapy for cases where complete tumor resection is challenging. In this case, the patient has previously undergone multiple brain tumor resections and received radiation therapy.
