Current management of non-metastatic muscle invasive bladder cancer (MIBC) includes radical cystectomy and cisplatin-based neoadjuvant chemotherapy (NAC), offers a 5-year survival rate of approximately 50% and is associated with significant toxicities. A growing body of evidence supports the role of liquid biopsies including circulating tumour DNA (ctDNA) as a prognostic and predictive marker that could stratify patients according to individualised risk of progression/recurrence. Detectable ctDNA levels prior to radical cystectomy have been shown to be correlated with higher risk of recurrence and worse overall prognosis after cystectomy. In addition, ctDNA status after NAC/neoadjuvant immunotherapy is predictive of the pathological response to these treatments, with persistently detectable ctDNA being associated with residual bladder tumour at cystectomy. Finally, detectable ctDNA levels post-cystectomy have been associated with disease relapse and worse disease-free (DFS) and overall survival (OS) and might identify a population with survival benefit from adjuvant immunotherapy.
Background: Two million non-emergency surgeries are being cancelled globally every week due to the COVID-19 pandemic, which will have a major impact on patients and healthcare systems. Methods: During the peak of the pandemic in the United Kingdom, we set up a multicentre cancer network amongst 14 National Health Service institutions, performing urological, thoracic, gynaecological and general surgical urgent and cancer operations at a central COVID-19 cold site. This is a cohort study of 500 consecutive patients undergoing surgery in this network. The primary outcome was 30-day mortality from COVID-19. Secondary outcomes included all-cause mortality and post-operative complications at 30-days. Results: 500 patients underwent surgery with median age 62.5 (IQR 51–71). 65% were male, 60% had a known diagnosis of cancer and 61% of surgeries were considered complex or major. No patient died from COVID-19 at 30-days. 30-day all-cause mortality was 3/500 (1%). 10 (2%) patients were diagnosed with COVID-19, 4 (1%) with confirmed laboratory diagnosis and 6 (1%) with probable COVID-19. 33/500 (7%) of patients developed Clavien-Dindo grade 3 or higher complications, with 1/33 (3%) occurring in a patient with COVID-19. Conclusion: It is safe to continue cancer and urgent surgery during the COVID-19 pandemic with appropriate service reconfiguration.
Urethral strictures significantly impact patients’ quality of life, with endoscopic treatments such as direct vision internal urethrotomy (DVIU) and dilatation showing high recurrence rates. Drug-coated balloon (DCB) treatment, which delivers paclitaxel locally after dilation, is an innovative, minimally invasive approach aimed at reducing fibrosis and stricture recurrence. Paclitaxel’s antiproliferative and antifibrotic properties inhibit excessive collagen deposition, improving long-term outcomes. DCB treatment is now included in guidelines for managing recurrent bulbar strictures less than 3 cm in length. Recent studies, including the ROBUST trials, have demonstrated the efficacy of Optilume in improving the International Prostate Symptom Score (IPSS) and maximum urinary flow rate (Qmax). DCB has also shown a significant reduction in reintervention rates compared with endoscopic treatments in long-term studies, confirming its safety profile. However, the durability of DCB in complex or longer strictures remains uncertain, and its role as a salvage therapy post-urethroplasty requires further investigation. DCB represents a promising, cost-effective advancement in managing recurrent bulbar urethral strictures, particularly for patients unsuitable for urethroplasty. Future research should focus on refining patient selection criteria and exploring indications for other anatomical sites.

Ameloblastoma is a rare odontogenic neoplasm of the jaw. It usually behaves as a benign, slow growing tumour of the oral cavity with a high recurrence rate, especially when it is inadequately resected. A small proportion of ameloblastomas metastasize to distant organs, with lungs representing the most common site of metastatic spread. In this report, we present the case of a middle-aged man with two pulmonary nodules and a history of mandibular ameloblastoma excised 10 years prior to this radiological finding. Following resection and histopathological analysis of the lung lesion, a diagnosis of metastatic ameloblastoma was confirmed. No local recurrence of the primary tumour was identified. At 1-year follow-up, the patient had no evidence of local or metastatic disease.
