RESUMEN

OBJECTIVE: To identify patient characteristics and surgical factors predictive of complications requiring mid-urethral sling (MUS) revision/removal. DESIGN: Case-control study. SETTING: Tertiary academic centre in Canada. POPULATION: One hundred and seven women undergoing MUS revision/removal between 2005 and 2016 were matched with 214 controls by date of index MUS procedure (2:1 ratio). METHODS: Data on patient and surgical factors were obtained via manual electronic and paper chart review. Three sets of pre-specified simple and multivariable logistic regression models were fitted to: (1) examine previously reported risk factors for MUS revision after primary surgical treatment; (2) identify preoperative predictors of MUS complications requiring revision/removal; and (3) identify surgical factors associated with this outcome after adjusting for potential confounding factors. MAIN OUTCOME MEASURES: Crude and adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) for patient and surgical factors. RESULTS: The median time to MUS revision was 153 days (interquartile range, IQR 49-432 days). Active smoking status (OR 2.29, 95% CI 1.13-4.63, P = 0.03), having had a previous hysterectomy (OR 3.88, 95% CI 2.02-7.46, P < 0.01), and undergoing concomitant pelvic organ prolapse surgery at the time of the index MUS procedure (OR 2.63, 95% CI 1.32-5.52, P < 0.01) were independently associated with the need for MUS revision/removal. Sling type (obturator versus retropubic), method of tensioning (to cough versus over instrument), anaesthetic type, and estimated blood loss were not associated with this outcome in the analysis presented here. CONCLUSIONS: Active smoking status, having had a previous hysterectomy, and undergoing concomitant surgery for pelvic organ prolapse are risk factors for requiring subsequent MUS revision/removal. TWEETABLE ABSTRACT: Risk factors for sling revision include smoking, previous hysterectomy, and concomitant prolapse surgery.

RESUMEN

BACKGROUND: The incidence of vulvar squamous cell carcinoma (VSCC) has been on the rise since the 1990s. There has been no new treatment for advanced and recurrent disease in decades, with most women succumbing to the disease. Despite two distinct etiologies of VSCC, human papillomavirus (HPV)-associated and HPV-independent disease, there is no difference in therapeutic options. METHODS: A literature review was carried out by searching EMBASE and Medline databases between January 1990 and March 2016 by pairing the keywords of vulvar carcinoma, vulva cancer, vulvar and vulva with molecular markers involved in the cell cycle, apoptosis and angiogenesis. Molecular targets of prognostic significance were identified and targeted agents of therapeutic relevance to both HPV-independent and HPV-associated VSCC were then reviewed. RESULTS: Recent advances in our understanding of the molecular biology of VSCC provide insight into the future management of VSCC with molecular targeted therapies. Aberrant cell cycle activity is common in both HPV-associated and HPV-independent VSCC and is characterized by overexpression of p53, Rb and cyclin D1, supporting targeting of these protein products and their downstream pathways. Extracellular regulators of cellular activity, such as EGFR, as well as inhibitors of angiogenesis are being clinically evaluated in VSCC. HPV-independent VSCC is characterized by actionable mutations, including PI3K, CDKN2A and PTEN. In HPV-associated disease, therapeutic vaccines targeting the E6 and E7 HPV oncogenes and immune-based therapies are under investigation. CONCLUSION: There has been a paucity of clinical trials in recent years in this neglected women's cancer. Directed therapy against cell cycle regulatory molecules and extracellular proteins and the inhibition of angiogenesis are of broad therapeutic relevance in VSCC. Therapeutic strategies that target actionable mutations should be explored. In HPV-associated VSCC, novel treatments that exploit the virology of HPV and/or enhance the host immune response merit further study.
