Cytoreductive surgery plus chemotherapy versus chemotherapy alone for recurrent epithelial ovarian cancer.

OBJECTIVES: This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To evaluate the benefits and harms of secondary CRS and chemotherapy in comparison to chemotherapy alone for women with platinum-sensitive recurrent epithelial ovarian cancer.

Efficacy and diagnostic reliability of intraoperative frozen section in the surgical management of early-stage cervical cancer.

OBJECTIVES: To evaluate pre-operative radiology and histopathology findings in cervical cancer lymphadenopathy detection, allowing targeted frozen section examination (FSE). DESIGN: A retrospective analysis was conducted of 203 early-stage cervical cancer patients between 2010 and 2019 in a tertiary centre. PARTICIPANTS/MATERIALS, SETTING, METHODS: All patients had histologically confirmed cervical cancer and underwent magnetic resonance imaging (MRI) prior to intraoperative FSE. The primary objectives of the study were: to determine the diagnostic accuracy of intraoperative FSE in the identification of lymph node metastases (LNM) in early stage cervical cancer by correlation with final results obtained using standard histopathology techniques, and to examine different preoperative, intraoperative, demographic, radiological, and histopathological factors which could identify those at greatest risk of nodal disease and hence predict those most likely to benefit from FSE, enabling more selective and targeted use. RESULTS: 19 patients were found to have LNM (9.36%) at FSE. Patients were at increased risk of LNM by 6-fold with positive LVSI, 3-fold with MRI lymphadenopathy and 3.5-fold with MRI visible disease. The presence of lymphadenopathy on MRI and positive LVSI in combination increased the risk of LNM by 19-fold. LIMITATIONS: We acknowledge that FSE is expensive and unpredictably time intensive, exposing patients to increased surgery duration and associated risk. We also recognise that it may not be feasible for all patients. Finally, the analysis is limited by retrospective nature of the study. CONCLUSIONS: By application of the preoperative risk stratification algorithm, we may suggest that FSE can be a useful tool in high-risk patients.

The role of the multidisciplinary team in surgical management of intractable tubo-ovarian abscess as a late sequelae of challenging Crohn's disease in the modern era: A case report and review of current literature.

Chronic, severe Crohn's disease in a young female patient can result in surgical complexity. The rarity of the presentation of intractable pelvic abscesses within this etiology with additional considerations given to fertility concerns and hence requirement for input from a multi-disciplinary team makes this a vital case in building a consensus for evidence-based surgical management. A 29-year-old nulliparous woman was referred to our tertiary centre for surgical management of Crohn's disease with known tubo-ovarian abscess and abdominoperineal and abdominal wall sinuses. Her previous surgical history included 4 midline laparotomies, subtotal colectomy and proctectomy with stoma formation. The patient underwent egg collection to preserve fertility. This was followed by midline laparotomy and abdominoperineal resection, which involved a retrograde radical modified hysterectomy using the Hudson technique, alongside excision of the perineal sinus, with reconstruction of the perineal defect using an internal pudendal artery perforator gluteal fold flap, and in addition to excision and drainage of the abdominal wall abscess. Involvement was sought from gynecological oncology, colorectal, urology, plastics, stoma, fertility, microbiology, and gastroenterology teams, which enabled successful preservation of end organ function and improvement in patient psychological well-being. This case is a paradigm of surgical challenge, requiring expert gynecological oncology techniques including a retroperitoneal approach, nerve and vessel sparing considerations alongside colorectal and urological procedures. Moreover, we believe that our blueprint for effective multi-disciplinary practice will inform the future management of gynecological surgery. Therefore this report aims to contribute towards the optimum management of the gynecological sequelae of Crohn's disease.

Rare Mullerian adenosarcoma of the uterine cervix arising on a background of endometriosis: A diagnostic challenge with risk of malignant transformation-A case report and review of the current literature.

Endometriosis may contribute to Mullerian adenosarcoma development but makes diagnosis challenging given similar symptoms. Survival benefit has not been definitively shown for chemotherapy, hormonal therapy, or radiotherapy, consolidating surgery as the mainstay treatment. Local excision may be a treatment option for patients with confined tumors wishing to preserve their fertility.

The application of pringle manoeuvre, type three liver mobilisation, full thickness diaphragmatic resection with primary closure technique and peritonectomy in the management of advanced ovarian malignancy.

OBJECTIVE: We present an educational technique for the safe completion of complete cytoreduction of diaphragmatic disease for the management of advanced ovarian malignancy. METHODS: We demonstrated these steps with attention to anatomical landmarks and surgical approaches, considering intraoperative and postoperative morbidity and mortality. RESULTS: We present the case of a 49-year-old female patient diagnosed with suspected stage 3C ovarian malignancy following diagnostic laparoscopy. We demonstrate the surgical application of the Pringle manoeuvre, type 3 liver mobilisation, and full-thickness diaphragmatic resection. This was completed with a primary closure technique, with integrity ensured through the performance of an air test and Valsalva manoeuvre. Final histology confirmed a serous borderline tumour with invasive implants within a port site nodule (stage 4A). CONCLUSION: This technique affirms the essential skills in gynaecological oncology training and details a challenging case requiring advanced surgical skills and knowledge, with specific consideration for intraoperative multidisciplinary decision-making.

Adamantinoma: A review of the current literature.

Adamantinoma is a rare primary low-grade malignant tumour of the appendicular skeleton most commonly found in the tibia. It has an indolent course, with local recurrences and lung metastases occurring over a protracted duration. There have been several suggestions pertaining to a vascular origin in the literature, however, histogenesis remains unclear. Currently, guidelines are not available pertaining to clinical management. This paper presents an overview of the current literature regarding this unusual malignancy. It also explores disease etiology and acknowledges the benefits and challenges of investigations pertaining to diagnosis. It recognizes a paucity of recommendations regarding appropriate surveillance and follow up. This review aims to assist clinicians in the building of a consensus opinion for optimal adamantinoma case management under current circumstances where formal guidelines do not exist.

Bartholin's gland carcinoma-the diagnostic and management challenges of a rare malignancy-a case report and review of current literature.

Background: Bartholin's gland carcinoma (BGC) accounts for approximately 5% of all vulval malignancies-making it an extremely rare malignancy of the female genital tract. It commonly manifests as a painless unilateral mass, near the introitus. BGC more commonly occurs in post-menopausal women. Unfortunately, over half of cases are associated with a missed or delayed diagnosis as it is often mistaken for a Bartholin's gland cyst or abscess. These tumours have a predilection for local and perineural invasion. Magnetic resonance imaging (MRI) is the imaging modality of choice for suspected Bartholin's tumour. Although no current guidance dedicated to the management of BGC exists, the majority of cases are treated by primary excision and bilateral groin node dissection (GND). Chemoradiotherapy has a role in both the adjuvant and palliative setting. BGC are typically associated with more advanced disease at presentation, higher rates of recurrence and poorer prognosis than other vulval cancer sub-types. Case Description: We share a case report of primary BGC-supported by high-quality radiological and surgical images; and further supplemented by a detailed review of current literature. Conclusions: We aim to generate improved clinician awareness of this rare pathology, highlighting the need for vigilance to avoid misdiagnosis and subsequent treatment delay; as well as contribute towards generating consensus on the approach to management of this gynaecological malignancy.

The Prognostic Characteristics and Recurrence Patterns of High Grade Endometrioid Endometrial Cancer: A Large Retrospective Analysis of a Tertiary Center.

High grade endometrioid endometrial cancer (HGEEC) is a heterogeneous group of tumors with unclear prognostic features. The aim of the present study is to evaluate the independent risk factors for recurrence and mortality and to describe the recurrence patterns of HGEEC. Ninety-six consecutive cases of HGEEC treated with primary surgery in a single Tertiary Center were retrospectively reviewed. Clinicopathological and treatment details were recorded, and all patients were closely followed up. Disease-free, overall and cancer-specific survival rates were 83.8%, 77.8% and 83.6%, respectively. Cervical stromal involvement was independently related to recurrence (HR = 25.67; 95%CI 2.95-223.30; p = 0.003) and cancer-related death (HR = 15.39; 95%CI 1.29-183.43; p = 0.031) after adjusting for other pathological and treatment variables. Recurrence rate was 16%, with 60% of these cases having lung metastases and only one case with single vaginal vault recurrence. 81.81% of the recurrences presented with symptoms and not a single recurrence was diagnosed in routine follow-up clinical examination. In conclusion, the recurrence pattern may suggest that patient-initiated follow-up (PIFU) could be considered a potential alternative to clinical-based follow-up for HGEEC survivors, especially for patients without cervical involvement and after two years from treatment. Additional caution is needed in patients with cervical stromal involvement.

Mixed Endometrial Epithelial Carcinoma: Epidemiology, Treatment and Survival Rates-A 10-Year Retrospective Cohort Study from a Single Institution.

Mixed endometrial carcinoma (MEEC) refers to rare endometrial tumours that are composed of two or more distinct histotypes, at least one of which is serous or clear cell. The aim of this study was to evaluate the epidemiology, treatment outcomes and survival rates of patients with mixed endometrial carcinoma. The medical records of 34 patients diagnosed with MEEC between March 2010 and January 2020 were reviewed retrospectively. Clinicopathological variables and treatment strategies were assessed, and overall survival and disease-free survival rates were evaluated. The histology of endometrioid and serous component was found in 26 (76.5%) patients, followed by serous and clear-cell components (5/34, 14.5%) and mixed endometrioid serous and clear-cell components (3/34, 8.8%). The median age at diagnosis was 70 years (range 52-84), and the median follow-up time was 55 months. The 5-year disease-free survival and the 5-year overall survival were 50.4% and 52.4%, respectively. Advanced disease stage was identified as an independent predictor of inferior disease-free (<0.003) and overall survival (p < 0.001). Except for stage, none of the traditional prognostic factors was associated with disease recurrence or death from disease. MEECs represent rare high-risk endometrial carcinomas with significant diagnostic and treatment challenges. Undoubtedly, the implementation of a molecular analysis can offer further diagnostic and management insights.

Thoracic Gorham-Stout disease masquerading as an ovarian malignancy: a differential diagnosis in non-malignant causes of raised Ca-125 and overview of this rare pathology.

Gorham-Stout disease (GSD) is thought to be due to uncontrolled proliferation of vascular and lymphatic structures within bone tissue causing destruction and osteolysis of bone. We present a patient in her mid-40s who reported chronic shoulder pain, a pleural effusion and irregular periods. Investigations showed osteolysis of her ribs, pleural effusions, an ovarian mass and a raised carbohydrate antigen 125 (Ca-125). She was subsequently diagnosed with GSD, and referred to gynaecology-oncology in consideration of potential ovarian malignancy. GSD is a diagnosis of exclusion that requires a high degree of clinical suspicion, as well as multiple investigations to achieve diagnosis. Clinicians rely on a small number of case reports to provide guidance for this. Therefore, this report provides an overview of a rare pathology, considers the differentials of a raised Ca-125 and describes how a pleural effusion, which links them both, alarmed us regarding an incidental finding of an ovarian cyst.

Late presentation during the COVID-19 pandemic of severe procidentia: a high-grade poorly differentiated sarcoma of unknown origin.

High-grade poorly differentiated sarcomas of unknown primary origin constitute a rare entity and are characterised by wide histopathological diversity and atypical presentations. We present such an unusual case attending with severe procidentia in a 68-year-old postmenopausal female. On review of the literature, there are no similar cases reported. Herein, we present this case as in view of its rare clinical appearance combined with the advanced and histologically uncertain nature of the tumour, which raised significant challenges regarding diagnosis and surgical management in considerations of oncological hygiene and risk of tumour spillage. This was further potentiated by delay in diagnosis and treatment due to the COVID-19 pandemic.

Perivascular epithelioid cell tumour and investigation of genetic susceptibility.

A patient in her 60s was referred to be investigated for an incidental large uterus with a history of renal cell carcinoma and melanoma. Uterine biopsy revealed features of perivascular epithelioid cell tumours (PEComas) and she underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Final histology confirmed PEComa with malignant features. Genomic studies did not reveal any deleterious germline variants; however, in view of her history, she is now under a 6-month follow-up with gynaecology-oncology. PEComas are rare tumours associated with tuberous sclerosis and melanoma, sharing genetic abnormalities. Gynaecological PEComas usually present with no or non-specific symptoms. Preoperative investigations are often misleading. Final histology and immunohistochemistry have overlapping features with smooth muscle tumours. Although rare, PEComas need to be treated aggressively to minimise the potential risk of spread. There is currently little evidence about further adjuvant treatment and no clear follow-up protocol. However, the literature suggests that the prognosis is generally good.

Ten-Step Surgical Approach to Management of Pathology of the Ischiorectal Fossa-A Review of the Literature and Application in a Rare Pelvic Schwannoma.

Objective: The ischiorectal fossa is a key anatomical location with boundaries and internal structures owing distinct contributions to function and quality of life. Methods: We highlight the importance of management of pathology in this deep anatomically complex location. Results: We present a ten-step multidisciplinary surgical approach; achieving en bloc radical excision with primary closure and reassuring outcomes. Schwannomas are benign slow-growing nerve sheath tumors. Conclusions: Pelvic schwannomas are rare with only 3 reported cases of the pudendal nerve. We also offer an overview of this rare pathology whilst acknowledging a paucity of recommendations regarding management of disease of the ischiorectal fossa.

Radical abdomino-pelvic surgery in the management of uterine carcinosarcoma with concomitant para-aortic lymphadenopathy metastasising from anal carcinoma.

Uterine carcinosarcomas are aggressive gynaecological cancers comprising less than 5% of uterine malignancies. We present the case of a woman in her 70s with a complicated history of advanced anal carcinoma treated with pelvic radiotherapy and multiple laparotomies, who was referred to gynae-oncology following MRI surveillance imaging showing evidence of endometrial carcinoma and para-aortic lymphadenopathy. Successful surgical excision required multidisciplinary teamwork between gynae-oncology, colorectal and urology surgeons. The patient underwent midline laparotomy, with adhesiolysis, ileum resection and side to side anastomosis, posterior exenteration, left kidney mobilisation and suspension, para-aortic lymph node debulking and left ureteric stent insertion. Significant challenge was posed by the extensive adhesions from previous laparotomies and the debulking of the para-aortic lymph nodes around the renal vessels. This case demonstrates the importance of a multidisciplinary approach in complex pelvic surgery and the vitality of good communication between colleagues in achieving effective patient care.

Approach to Radical Hysterectomy for Cervical Cancer in Pregnancy: Surgical Pathway and Ethical Considerations.

INTRODUCTION: Cervical cancer is currently the fourth most common cancer in women and in the poorest countries this neoplasia still represents a widespread and potentially lethal disease. We present a rare case of cervical cancer in pregnancy, analyzing the historical changes behind the procedure of radical hysterectomy for cervical cancer and discussing variations in surgical techniques and anatomical definitions that have since been proposed. RESULTS: We present the case of a 33-year-old patient who attended with vaginal bleeding in the second trimester of pregnancy. Examination revealed an abnormal looking cervix, with investigations concluding stage IIb squamous cell carcinoma. Following extensive discussion regarding management options, the patient went on to have a peripartum foetocidal type III nerve sparing radical Wertheim hysterectomy at 18 weeks gestation with conservation and transposition of the ovaries above the level of the pelvic brim. The patient recovered well without significant morbidity and received further input from fertility and psychological medical teams in addition to adjuvant treatment within the department of clinical oncology. DISCUSSION: This case represents several elements of great interest and learning. Notably, we highlight this both due to the surgical challenges that a gravid uterus presents in the execution of a radical hysterectomy; and regarding the compassionate care demonstrated by the team - not only in supporting the patient and her partner in a period of profound turmoil in terms of the management of their cancer diagnosis and unborn child, but also regarding the uncertainty in consideration of the oncological and fertility related outcomes. CONCLUSION: This manuscript adds to the growing literature on the appropriate use of radical surgery for cervical cancer, more specifically during pregnancy and in consideration of such ethical dilemma, where management guidelines do not exist to aid clinicians further in their provision of treatment.

Adamantinoma: metastatic disease masquerading as a gynaecological malignancy.

Adamantinoma is a rare low-grade malignancy of the appendicular skeleton with unclear histogenesis. We present the case of a 65-year-old woman with known recurrent and metastatic right tibial disease despite clear resection margins. On further investigation, a positron emission tomography-CT scan identified a primary breast lesion and an 11 cm mass in the right iliac fossa of suspected ovarian malignancy amenable to surgical resection. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and resection of a retroperitoneal mass arising from the pelvic sidewall encompassing the iliac vasculature. The patient made an uneventful recovery with histology confirming disease metastasising to the pelvis. Currently, clinical management guidelines are not available. We present an overview of adamantinoma and highlight a previously undocumented gynaecological oncology surgical approach to this novel disease location. Regarding metastases, we acknowledge the challenges of investigation pertaining to disease site and origin as well as a paucity of recommendations for surveillance and follow-up.

Primary peritoneal mucinous cystadenocarcinoma mimicking possible recurrent ovarian mucinous cystadenoma: coincidental pathology or a spectrum of disease?

We present the case of a 32-year-old woman with a previous surgical history of benign mucinous cystadenoma resected in 2012 who underwent magnetic resonance cholangiopancreatography following her second pregnancy in 2020. This demonstrated a large cystic mass in the left subdiaphragmatic space. Histopathology confirmed a well-differentiated primary peritoneal mucinous cystadenocarcinoma displaying cells of a Mullerian origin. We subsequently discuss the aetiology of these conditions separately and explore the possibility of a connection between the two regarding origin or potential malignant transformation that may otherwise have occurred coincidentally in this young patient. We also acknowledge a paucity of evidence regarding subsequent management strategies.

Atypical presentation of intravascular leiomyomatosis mimicking advanced uterine sarcoma: modified laterally extended endopelvic resection with preservation of pelvic neural structures.

Intravascular leiomyomatosis is a rare, benign tumour of myometrial smooth muscle. Despite being non-invasive, these tumours can proliferate aggressively within vascular structures including pelvic vessels, the vena cava and the heart. We discuss a 77-year-old woman presenting with a 9 cm uterine mass extending into the right adnexa and ovarian vein. Following hysteroscopic biopsy, palliative radical surgical resection was performed for suspected stage IV leiomyosarcoma. Tumour extension into the pelvic sidewall and obturator fossa indicated a modified laterally extended endopelvic resection combined with skeletonisation and preservation of the pelvic neurovasculature, ultimately providing a curative procedure with minimal functional neurological morbidity. We present this unusual case to assist in the development of a consensus for optimal case management where formal guidelines are not yet available. We summarise current understanding of intravascular leiomyomatosis and highlight the value of advanced surgical techniques using knowledge of complex ontogenetic and pelvic neuroanatomy in its management.

Glucose-fructose enhances performance versus isocaloric, but not moderate, glucose.

PURPOSE: The effects of glucose-and-fructose (GF) coingestion on cycling time trial (TT) performance and physiological responses to exercise were examined under postprandial conditions. METHODS: Eight trained male cyclists (age, 25 ± 6 yr; height, 180 ± 4 cm; weight, 77 ± 9 kg; V˙O2max, 62 ± 6 mL·kg·min) completed the study. Subjects ingested either an artificially sweetened placebo (PL), a moderate-glucose beverage (MG, 1.03 g·min), a high-glucose beverage (HG, 1.55 g·min), or a GF beverage (1.55 g·min, 2:1 ratio) during approximately 3 h of exercise, including 2 h of constant-load cycling (55% Wmax, 195 ± 17 W), immediately followed by a computer-simulated 30-km TT. Physiological responses (V˙E, V˙O2, RER, HR, blood glucose level, blood lactate level, and RPE) and incidences of gastrointestinal distress were assessed during early (15-20 min), middle (55-60 min), and late exercise (115-120 min) and during the TT. Magnitude-based qualitative inferences were used to evaluate differences between treatments. RESULTS: In comparison with that in PL (52.9 ± 3.7 min), TT performances were faster with GF (50.4 ± 2.2 min, "very likely" benefit), MG (51.1 ± 2.4 min, "likely" benefit), and HG (52.0 ± 3.7 min, "possible" benefit). GF resulted in a "likely" improvement versus HG (3.0%) and an "unclear" effect relative to MG (1.2%). MG was "possibly" beneficial versus HG (1.8%). Few incidences of GI distress were reported in any trials. CONCLUSIONS: GF ingestion seems to enhance performance, relative to PL and HG. However, it is unclear whether GF improves performance versus moderate doses of glucose.
