Background: Local recurrence (LR) after radical nephrectomy (RN) for kidney cancer is uncommon. Our objectives were to analyse characteristics and therapeutic options of LR after RN and to identify survival prognostic factors.
Materials And Methods: From a multi-institutional retrospective database, we identified 72 patients who experienced LR after RN.
Results: Mean time to LR was 26.5 ± 3.3 months. The location of the recurrence was renal fossa, regional lymph node, homolateral adrenal and both renal fossa and regional lymph node for 43 (59.7%), 27 (37.5%), 9 (12.5%) and 7 (9.7%) patients, respectively. Patients were treated by surgery, systemic therapies, combination of therapies and palliative treatment in 24 (33.3%), 18 (25%), 24 (33.3%) and 6 (8.4%) cases, respectively. Within a mean follow-up of 26.4 ± 3.3 months from the date of local recurrence, 12 (16.6%) patients were alive without disease, 30 (41.7%) patients were alive with disease, 30 patients (41.6%) died including 28 (38.8%) from the disease. In multivariate analysis, time to recurrence <1 year (P < 0.001; HR: 4.81) and surgical treatment (P = 0.027; HR: 0.33) were predictive factors.
Conclusions: Local recurrence after radical nephrectomy is associated with poor prognosis. The time to recurrence and the completeness of the surgical treatment are major prognostic factors.

Introduction: Aneurysmal bone cysts are locally aggressive bone lesions. The aim of this study was to evaluate safety and effectiveness of radio-opaque gelified ethanol sclerotherapy in treating primary aneurysmal bone cyst.
Materials And Methods: In this single-center, retrospective study (January 1st, 2012, to June 30th, 2024), 32 patients with primary aneurysmal bone cysts were treated with percutaneous sclerotherapy using radio-opaque gelified ethanol at various skeletal sites.
Patterns, timing and predictors of recurrence following pancreaticoduodenectomy for pancreatic ductal adenocarcinoma: an international multicentre retrospective cohort study.

Background: Most patients undergoing pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) develop recurrence. No previous studies have investigated predictors of local-only recurrence following PD for PDAC. Our study aimed to determine timing, pattern and predictors of any-site and local-only recurrence following PD for PDAC.

A calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour of epithelial origin accounting for approximately 1% of all odontogenic tumours. The intraosseous form occurs more commonly in the posterior mandible whereas the extraosseous form is common in the anterior maxilla. CEOT is often asymptomatic and presents with a painless swelling of the mandible.

A young man in his 30s presented to us with multiple episodes of syncope and exertional dyspnoea for the last 2 weeks. He was diagnosed with squamous cell carcinoma of the lower one-third of the oesophagus in 2021 for which he was treated with neoadjuvant chemoradiotherapy, followed by McKeown oesophagectomy. At 2-year follow-up, he had developed a soft tissue swelling in the scalp, which was diagnosed as a tumour recurrence and radiotherapy was initiated.

Targeted organelle therapy is a promising therapeutic method for significantly regulating the tumor microenvironment, yet it often lacks effective strategies for leveraging synergistic enhancement effect. Engineered small extracellular vesicles (sEVs) are expected to address this challenge due to their notable advantages in drug delivery, extended circulation time, and intercellular information transmission. Herein, we prepare sEVs with pH and photothermal dual-responsiveness, which are encapsulated with hydrogels for a quadruple-efficient synergistic therapy.
