FARGO-360: a multi-disciplinary survey of practice and perspectives on provision of care for patients with frailty presenting with gynecological cancers in the UK and Ireland.

OBJECTIVES: Frailty has been associated with worse cancer-related outcomes for people with gynecological cancers. However, the lack of clear guidance on how to assess and modify frailty prior to instigating active treatments has the potential to lead to large variations in practice and outcomes. This study aimed to evaluate current practice and perspectives of healthcare practitioners on the provision of care for patients with frailty and a gynecological cancer. METHODS: Data were collected via a questionnaire-based survey distributed by the Audit and Research in Gynecological Oncology (ARGO) collaborative to healthcare professionals who identified as working with patients with gynecological malignancies in the United Kingdom (UK) or Ireland. Study data were collected using REDCap software hosted at the University of Manchester. Responses were collected over a 16 week period between January and April 2021. RESULTS: A total of 206 healthcare professionals (30 anesthetists (14.6%), 30 pre-operative nurses (14.6%), 51 surgeons (24.8%), 34 cancer specialist nurses (16.5%), 21 medical/clinical oncologists (10.2%), 25 physiotherapists/occupational therapists (12.1%) and 15 dieticians (7.3%)) completed the survey. The respondents worked at 19 hospital trusts across the UK and Ireland. Frailty scoring was not routinely performed in 63% of care settings, yet the majority of practitioners reported modifying their practice when providing and deciding on care for patients with frailty. Only 16% of organizations surveyed had a dedicated pathway for assessment and management of patients with frailty. A total of 37% of respondents reported access to prehabilitation services, 79% to enhanced recovery, and 27% to community rehabilitation teams. CONCLUSION: Practitioners from all groups surveyed considered that appropriate training, dedicated pathways for optimization, frailty specific performance indicators and evidence that frailty scoring had an impact on clinical outcomes and patient experience could all help to improve care for frail patients.

Integration of computer-aided automated analysis algorithms in the development and validation of immunohistochemistry biomarkers in ovarian cancer.

In an era when immunohistochemistry (IHC) is increasingly depended on for histological subtyping, and IHC-determined biomarker informing rapid treatment choices is on the horizon; reproducible, quantifiable techniques are required. This study aimed to compare automated IHC scoring to quantify 6 DNA damage response protein markers using a tissue microarray of 66 ovarian cancer samples. Accuracy of quantification was compared between manual H-score and computer-aided quantification using Aperio ImageScope with and without a tissue classification algorithm. High levels of interobserver variation was seen with manual scoring. With automated methods, inclusion of the tissue classifier mask resulted in greater accuracy within carcinomatous areas and an overall increase in H-score of a median of 11.5% (0%-18%). Without the classifier, the score was underestimated by a median of 10.5 (5.2-25.6). Automated methods are reliable and superior to manual scoring. Fixed algorithms offer the reproducibility needed for high-throughout clinical applications.

Post-operative pancreatic fistula following splenectomy with or without distal pancreatectomy at cytoreductive surgery in advanced ovarian cancer.

OBJECTIVE: Splenectomy with or without distal pancreatectomy may be necessary at time of cytoreductive surgery to achieve complete cytoreduction in advanced ovarian cancer. However, these procedures have been associated with peri-operative morbidity. The aims of this study were to determine the incidence of distal pancreatectomy among patients undergoing splenectomy during cytoreductive surgery for advanced ovarian cancer and to determine the incidence, management, treatment, and prognosis of patients with post-operative pancreatic fistula. METHODS: Retrospective cohort study of all consecutive patients with FIGO stage IIIC-IVB ovarian, fallopian tube, or primary peritoneal cancer who underwent splenectomy with or without distal pancreatectomy, during primary, interval, or secondary cytoreductive surgery between January 2007 and December 2017. All histologic subtypes were included; patients with borderline ovarian tumor and those undergoing emergency surgery were excluded from analysis. Univariate analyses for survival were generated by Kaplan-Meier survival curves and log-rank (Mantel-Cox) tests for statistical significance. Patients who underwent surgery for recurrence were excluded from survival analysis. Inter-group statistics were performed using Student's t-test for continuous variables, and chi-square test and Fisher's exact test for categorical variables. RESULTS: A total of 156/804 (19.4%) women underwent splenectomy, and of these 22 (14.1%) patients had distal pancreatectomy. Of patients who underwent splenectomy only, 2/134 (1.5%) developed grade B post-operative pancreatic fistula and 6/22 (27.3%) patients who underwent distal pancreatectomy developed grade B and C post-operative pancreatic fistula. Five (83.3%) of six of these patients were symptomatic. Distal pancreatectomy patients had a higher risk of developing post-operative pancreatic fistula when compared with patients who underwent splenectomy only (63.7% vs 9.7%, p=0.0001). Median length of hospital stay was longer in patients with post-operative pancreatic fistula: 16.5 (range 7-38) days compared with 10 (range 7-15) days (p=0.019). There was no progression-free survival (p=0.42) and disease-specific survival (p=0.33) difference between patients undergoing splenectomy with or without distal pancreatectomy. CONCLUSION: Clinically relevant post-operative pancreatic fistula is a relatively frequent complication (27.3%) following distal pancreatectomy and it is a possible complication after splenectomy only (1.5%).

BRAF Wild-type, PTEN Mutant Malignant Uveal Melanoma Arising Within a Mature Ovarian Teratoma: A Case Report and Review of the Literature.

Mature cystic teratomas are common in women of all ages; however, malignant transformation within them is rare and difficult to diagnosis preoperatively. Primary melanoma of the ovary is exceptionally rare and only occurs in relation to a teratoma where it can originate from sporadic somatic mutagenesis within epidermal junctional melanocytes, through malignant transformation of a benign nevus formed within the mature cystic teratoma or from other well differentiated pigment-containing structures such as the uvea. We present a case of primary malignant melanoma arising within a mature cystic teratoma in a young patient, who ultimately developed widespread metastasis necessitating systemic therapy. Our case highlights the role of molecular medicine not only in forming an understanding the origin of the melanoma, but also guiding targeted systemic therapies. Alongside the case we present a review of the literature describing the incidence of molecular aberrations within melanoma as well as the established and emerging techniques and cytotoxic agents for malignant melanoma.

Borderline Ovarian Tumors: Fifteen Years' Experience at a Scottish Tertiary Cancer Center.

OBJECTIVES: Since the recognition of borderline ovarian tumors (BOTs) in the 1970s, the management of this subset of epithelial ovarian tumors has presented a challenge to clinicians. The majority present at an early stage, but their diagnosis is often only made following surgery, hence the heterogeneity of surgical management. Borderline ovarian tumors are morphologically diverse, and their behavior is subsequently also heterogeneous. We aimed to assess recurrence rates and the rate of malignant transformation in patients diagnosed with BOT. Secondary objectives included a review of current management and assessment of tumor markers, stage, cyst dimensions, and the presence of micropapillary features as prognostic indicators of recurrence. METHODS: This retrospective cohort study included all patients treated with BOT between 2000 and 2015 in the southeast region of Scotland. Clinical, surgicopathological, and follow-up data were collated. Data were analyzed with reference to recurrence and malignant transformation. RESULTS: Two hundred seventy-five patients underwent treatment for BOT in the study period. Surgical management was highly variable. A diagnosis of recurrent/persistent BOT or ovarian malignancy following initial treatment of BOT was rare, with only 12 (4%) of 275 cases. There were 7 cases (3%) of ovarian malignancy. Advanced International Federation of Gynecology and Obstetrics stage was the most prominent prognostic factor. Elevated preoperative serum CA-125 and the presence of micropapillary features correlated with advanced stage at presentation. With a lack of clear guidance, follow-up was highly variable with a median of 43 months (0-136 months). CONCLUSIONS: To our knowledge, this study is the largest BOT cohort in the United Kingdom. Recurrent disease is rare in optimally staged, completely resected, early-stage BOT, without high-risk features. Caution is needed in women electing not to undergo completion staging after diagnosis and in those opting for a fertility-preserving approach. Thorough informed consent and clear plans for surveillance and follow-up are needed with consideration of delayed completion surgery as appropriate.

Locally advanced vulva cancer: A single centre review of anovulvectomy and a systematic review of surgical, chemotherapy and radiotherapy alternatives. Is an international collaborative RCT destined for the "too difficult to do" box?

INTRODUCTION: Treatment of locally advanced vulva cancer (LAVC) remains challenging. Due to the lack of randomised trials many questions regarding the indications for different treatment options and their efficacy remain unanswered. METHODS: In this retrospective study we provide the largest published series of LAVC patients treated with anovulvectomy, reporting oncological outcomes and morbidity. Additionally, a systematic literature review was performed for all treatment options 1946-2015. RESULTS: In our case series, 57/70 (81%) patients were treated in the primary setting with anovulvectomy and 13 patients underwent anovulvectomy for recurrent disease. The median overall survival (OS) was 69months (1-336) with disease specific survival of 159months (1-336). Following anovulvectomy for primary disease, time to progression and OS were significantly higher in node negative disease (10 vs. 96months; 19 vs. 121months, p<0.0001). Post-surgical complications were observed in 36 (51.4%), the majority of which were Grade I/II infections. There was one peri-operative death. Review of the literature showed that chemotherapy, radiotherapy or combination treatments are alternatives to surgery. Evidence relating to all of these consisted mostly of small retrospective series, which varied considerably in terms of patient characteristics and treatment schedules. Significant patient and treatment heterogeneity prevented meta-analysis with significant biases in these studies. It was unclear if survival or morbidity was better in any one group with a lack of data reporting complications, quality of life, and long term follow-up. However, results for chemoradiation are encouraging enough to warrant further investigation. CONCLUSIONS: There remains inadequate evidence to identify an optimal treatment for LAVC. However, there is sufficient evidence to support a trial of anovulvectomy versus chemoradiation. Discussions and consensus would be needed to determine trial criteria including the primary outcome measure. Neoadjuvant chemotherapy or radiotherapy alone may be best reserved for the palliative setting or metastatic disease.

Hormone replacement therapy after treatment for a gynaecological malignancy.

PURPOSE OF REVIEW: Provision of hormone replacement therapy (HRT) to women following a diagnosis of a gynaecological malignancy is a complex and controversial area associated with a lack of published guidance. As the average age of women affected by gynaecological cancer decreases and survival following provision of effective therapies increases, clinicians face new considerations for longer-term health concerns of patients. Additionally, there is a growing understanding of the influence of tumour biology upon response to cytotoxic therapies and it is essential that we use this knowledge to guide provision of HRT. RECENT FINDINGS: Available evidence for ovarian, vulval, cervical, and endometrial cancers demonstrates no excess risk of recurrence in patients taking HRT with the exception of some subtypes of cancer (uterine sarcomas, granulosa cell, and low-grade serous ovarian cancer). Evidence for the incidence of hormone receptor status is suggestive that HRT may be ill-advised in an additional proportion of patients and we recommend characterization of all tumours in patients who may require HRT. SUMMARY: The risk and benefits of HRT should be evaluated for all women who undergo a premature menopause as a result of gynaecological malignancy to reduce menopausal symptoms and protect against cardiovascular and skeletal morbidity. There is no evidence to suggest a higher rate of disease recurrence in women using HRT in comparison to nonusers in the majority of gynaecological malignancies. Routine histological testing of tumours for hormone receptor status is an achievable goal and may help to stratify patients further into low and high-risk groups for hormone therapy.
