Vulval squamous cell cancer - does precursor lesion margin status affect recurrence-free survival after optimal surgical resection for early-stage disease?

OBJECTIVES: Vulval cancer accounts for around 4% of all gynaecological malignancies and most tumours ( > 90%) are of a squamous cell histotype. Most lesions arise on a background of differentiated VIN (dVIN) or lichen sclerosus (LS). Surgical treatment has undergone a paradigm shift with less radical surgery being attempted to preserve vulval structure and function, without compromising oncological outcome. MATERIAL AND METHODS: In this single site retrospective analysis, we consider the data from a tertiary oncology unit, to assess progression-free survival based on the presence of a precursor lesion at the margin of resection.123 patients with FIGO stage 1 vulvar SCC (n = 33 1A, n = 90 1B) were included. RESULTS: One Hundred Five patients (85%) had an associated precursor lesion (dVIN and/or LS). Within the follow-up period, 33 patients (26.8%) had invasive recurrence, of which 24 (72.7%) had surgical resection margins which were positive for a precursor lesion. In patients with an acceptable microscopically clear invasive resection margin of > 2 mm the presence of a precursor lesion at the margin conveyed a higher risk of malignant recurrence when compared to those with completely clear margins (HR = 2.42; 95% CI 1.14-5.16). CONCLUSIONS: This study adds to the available literature emphasising the clinical significance of dVIN or LS at the surgical margin of optimally resected disease. In those who have marginal involvement of a precancerous lesion, increased surveillance should be considered. Future work should explore the need for additional adjuvant therapy in this cohort.

Sertoli-Leydig tumor and DICER1 gene mutation: A case series and literature review.

OBJECTIVE: Sertoli-Leydig cell tumors (SLCTs) are rare neoplasms occurring in young women with 60% associated with DICER1 mutations. This is only the second published case series of patients with SLCTs with associated DICER1 gene alterations. DICER1 syndrome is a rare inherited tumor-susceptibility syndrome affecting organs such as the ovaries. We use this case series to inform readers on this increasingly important condition in gynecology. METHODS AND RESULTS: We present three young females presenting with secondary amenorrhoea, hirsutism, acne and in one case tonic-clonic seizures. All cases had high testosterone levels and an adnexal mass on ultrasound. Following surgical removal, pathology confirmed SLCTs and genetic testing followed. All three patients had DICER1 syndrome with two patients subsequently found to be related. DISCUSSION: The prevalence of DICER1 syndrome in the population is estimated to be 1 in 10 000 with a spectrum of sex cord stromal tumors affecting young women. The associated pathological classifications and management. This paper describes the DICER1 gene and the associated tumor predisposition syndrome alongside a surveillance protocol for use in clinical practice. It promotes discussion over the importance of early clinical genetics involvement in sex-cord stromal tumors and the associated difficulties in counseling in a young patient population. Genetic testing and early detection are imperative for targeted surveillance of at-risk organs to be performed but despite this there is no international guidance. The cases highlight the psychological impact of tumors in young patients and provokes an ethical discussion over DICER1 gene's inclusion in preimplantation genetics. CONCLUSIONS: DICER1 syndrome is a rare but increasingly important condition in pediatric and adolescent gynecology with a paucity of published data and case reports. This makes international consensus on management and surveillance difficult.

Musculoskeletal injuries in cross-speciality surgeons: a survey of UK-based doctors.

Musculoskeletal disorder (MSD) rates amongst surgeons are as high as 80% and injuries within the healthcare setting are an impending epidemic with a distinct lack of intervention to prevent it. The career-shortening impact this has on the cohort of highly trained workers within the National Health Service must be highlighted. This study was designed to be the first UK-based cross-speciality survey to establish the prevalence and impact of MSDs. A quantitative survey from the standardised Nordic Questionnaire was distributed compromising questions assessing the prevalence of musculoskeletal complaints in all anatomical zones. 86.5% of the surgeons reported musculoskeletal discomfort over the last 12 months, with 92% of respondents detailing issues over the last 5 years. 63% state this had an impact on their home life, with a further 86% believing their symptoms are related to posture at work. 37.5% of surgeons admitted to altering or stopping work due to MSDs. This survey demonstrates high rates of MSK injuries in surgeons with a certain subsequent impact on occupational safety and career length. Robotic surgery may be a solution to the impending problem however further research is needed with policies developed to protect our health workers.
