RESUMO
BACKGROUND: Survival benefit from surgical debulking of ovarian cancer (OC) is well established, but some women, despite total macroscopic clearance of disease, still have poor prognosis. We aimed to identify biomarkers to predict benefit from conventional surgery. METHODS: Clinical data from women debulked for high-stage OC were analysed (Hammersmith Hospital, London, UK; 2001-2014). Infinium's HumanMethylation27 array interrogated tumour DNA for differentially methylated CpG sites, correlated to survival, in patients with the least residual disease (RD; Hammersmith Array). Validation was performed using bisulphite pyrosequencing (Charité Hospital, Berlin, Germany cohort) and The Cancer Genome Atlas' (TCGA) methylation data set. Kaplan-Meier curves and Cox models tested survival. RESULTS: Altogether 803 women with serous OC were studied. No RD was associated with significantly improved overall survival (OS; hazard ratio (HR) 1.25, 95% CI 1.06-1.47; P=0.0076) and progression-free survival (PFS; HR 1.23, 95% CI 1.05-1.43; P=0.012; Hammersmith database n=430). Differentially methylated loci within FGF4, FGF21, MYLK2, MYLK3, MYL7, and ITGAE associated with survival. Patients with the least RD had significantly better OS with higher methylation of MYLK3 (Hammersmith (HR 0.51, 95% CI 0.31-0.84; P=0.01), Charité (HR 0.46, 95% CI 0.21-1.01; P=0.05), and TCGA (HR 0.64, 95% CI 0.44-0.93; P=0.02)). CONCLUSIONS: MYLK3 methylation is associated with improved OS in patients with the least RD, which could potentially be used to determine response to surgery.

Parapneumonic pleural effusion is a common complication of pneumonia and can progress to empyema. Pleural empyema is a life-threatening infection, which can be treated with antibiotics and interventional drainage but in later stages often requires surgery. Here we describe the first case of pleural empyema following a COVID-19 infection with no respiratory failure in a previously healthy and athletic patient. The patient was initially treated with antibiotics and interventional drainage but was readmitted to hospital with symptom deterioration. He was then referred for surgery and underwent an uneventful thoracoscopic washout with partial decortication. The preoperative SARS-CoV2 swab was negative. The patient recovered fully and could be discharged.

International guidelines recommend colonoscopy following hospitalisation for acute diverticulitis. There is a paucity of evidence supporting the efficacy of colonoscopy in this context, particularly for patients with CT-diagnosed uncomplicated left-sided diverticulitis. This study aims to investigate the frequency that colorectal cancer (CRC) and advanced adenomas (AA) are identified during follow-up colonoscopy after hospitalisation with CT-proven left-sided diverticulitis for the first time in a UK population. In this single-centre retrospective-cohort study all patients presenting with CT-diagnosed uncomplicated left-sided diverticulitis between 2014 and 2017 were identified. The incidence of histologically confirmed CRC and AA identified at follow-up colonoscopy 4-6 weeks following discharge was assessed. 204 patients with CT proven uncomplicated left-sided diverticulitis underwent follow-up colonoscopy. 72% were female and the median age was 63 years. There were no major complications. 22% of patients were found to have incidental hyperplastic polyps or adenomas with low-grade dysplasia. No CRC or AA were found. Routine colonoscopy following acute diverticulitis in this cohort did not identify a single CRC or AA and could arguably have been omitted. This would significantly reduce cost and pressure on endoscopy departments, in addition to the pain and discomfort that is commonly associated with colonoscopy.
