FIGO staging for carcinoma of the vulva : 2021 revision

To revise the FIGO staging for carcinoma of the vulva using a new approach that involves analyses of prospectively collected data. The FIGO Committee for Gynecologic Oncology reviewed the recent literature to gain an insight into the impact of the 2009 vulvar cancer staging revision. The Committee resolved to revise the staging with a goal of simplification and actively collaborated with the United States National Cancer Database to analyze prospectively collected data on carcinoma of the vulva. Many tumor characteristics were collected for all stages of vulvar cancer treated between 2010 and 2017. Statistical analysis was performed with SAS software. Overall survival was estimated based on tumor characteristics. Log-rank and Wilcoxon tests were used to analyze overall survival similarities between and within groups of tumor characteristics. Characteristics with similar survivals were then grouped into the same stages and substages. Kaplan–Meier overall survival curves were generated for the resulting stages and substages. There were 12 063 cases with available data. The resulting new staging for carcinoma of the vulva has two substages in Stage I, no substage in Stage II, three substages in Stage III, and two substages in Stage IV. The Kaplan–Meier overall survival curves showed clear separation between stages and substages. The 2021 vulvar cancer staging is the first from the FIGO Committee for Gynecologic Oncology to be derived from data analyses. This revision has a new definition for depth of invasion, uses the same definition for lymph node metastases utilized in cervical cancer, and allows findings from cross-sectional imaging to be incorporated into vulvar cancer staging. The 2021 FIGO staging for carcinoma of the vulva is data-derived, validated, and much simpler than earlier revisions.The American College of Surgeons’ (ACoS) Commission on Cancer (CoC) and National Cancer Database (NCDB).http://www.wileyonlinelibrary.com/journal/ijgohj2022Obstetrics and Gynaecolog

Endometrial cancer: A review and current management strategies: Part I SGO Clinical Practice Endometrial Cancer Working Group

• We present risk factors for endometrial cancer, including genetic predisposition. • We review the diagnostic and metastatic evaluation of women with endometrial cancer. • We describe the surgical management of early and advanced endometrial cancer. a b s t r a c t a r t i c l e i n f o Endometrial carcinoma is the most common gynecologic malignancy. A thorough understanding of the epidemiology, pathophysiology, and management strategies for this cancer allows the obstetrician-gynecologist to identify women at increased risk, contribute toward risk reduction, and facilitate early diagnosis. The Society of Gynecologic Oncology's Clinical Practice Committee has reviewed the literature and created evidence-based practice recommendations for diagnosis and treatment. This article examines: • Risk factors, including genetic predisposition • Diagnostic and metastatic evaluation • Surgical management of early and advanced cancer, including lymphadenectomy in early cancer

CCNE1 and survival of patients with tubo-ovarian high-grade serous carcinoma: An Ovarian Tumor Tissue Analysis consortium study

BACKGROUND: Cyclin E1 (CCNE1) is a potential predictive marker and therapeutic target in tubo-ovarian high-grade serous carcinoma (HGSC). Smaller studies have revealed unfavorable associations for CCNE1 amplification and CCNE1 overexpression with survival, but to date no large-scale, histotype-specific validation has been performed. The hypothesis was that high-level amplification of CCNE1 and CCNE1 overexpression, as well as a combination of the two, are linked to shorter overall survival in HGSC. METHODS: Within the Ovarian Tumor Tissue Analysis consortium, amplification status and protein level in 3029 HGSC cases and mRNA expression in 2419 samples were investigated. RESULTS: High-level amplification (>8 copies by chromogenic in situ hybridization) was found in 8.6% of HGSC and overexpression (>60% with at least 5% demonstrating strong intensity by immunohistochemistry) was found in 22.4%. CCNE1 high-level amplification and overexpression both were linked to shorter overall survival in multivariate survival analysis adjusted for age and stage, with hazard stratification by study (hazard ratio [HR], 1.26; 95% CI, 1.08-1.47, p = .034, and HR, 1.18; 95% CI, 1.05-1.32, p = .015, respectively). This was also true for cases with combined high-level amplification/overexpression (HR, 1.26; 95% CI, 1.09-1.47, p = .033). CCNE1 mRNA expression was not associated with overall survival (HR, 1.00 per 1-SD increase; 95% CI, 0.94-1.06; p = .58). CCNE1 high-level amplification is mutually exclusive with the presence of germline BRCA1/2 pathogenic variants and shows an inverse association to RB1 loss. CONCLUSION: This study provides large-scale validation that CCNE1 high-level amplification is associated with shorter survival, supporting its utility as a prognostic biomarker in HGSC

Recurrent breast carcinoma presenting as postmenopausal vaginal bleeding: A case report

• We discuss the recurrence of breast carcinoma presenting as postmenopausal vaginal bleeding in a patient on Tamoxifen therapy. • Case report illustrates widespread genital tract manifestation of recurrent disease at time of presentation and rapid disease progression. • Discusses the importance of maintaining broad differential in diagnosis of postmenopausal vaginal bleeding

Primary gynecologic melanoma: A report of two unusual cases

Background: Primary ovarian and cervical melanomas are extremely rare tumors with a poor prognosis. Diagnosis requires a high index of suspicion as presentation can mimic benign conditions clinically and other neoplasms histologically. Cases: A 41 year-old with an adnexal mass underwent surgical staging for a stage IA ovarian melanoma. Imaging revealed a brain metastasis treated with radiation. Subsequent nodal recurrence was treated with immune and targeted therapies. She is alive with disease at 61 months follow-up. A 54 year-old presented after endocervical melanoma was diagnosed with polypectomy. She underwent radical hysterectomy, lymphadenectomy, and adjuvant brachytherapy. Immediate post-treatment imaging revealed widespread liver and pulmonary metastasis, currently being treated with ipilimumab. Conclusion: Immunohistochemistry can facilitate the diagnosis of gynecologic melanoma, and multidisciplinary treatment is recommended

Epithelioid Trophoblastic Tumor: A Case Report and Review of the Literature

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic tumor. Cases of ETT present as abnormal vaginal bleeding in women of reproductive age, with low human chorionic gonadotropin (hCG) levels. ETT can be a sequela of any gestational event and can present in both intrauterine and extrauterine sites. Metastasis and death have been reported. We present a case of a 44-year-old female incidentally diagnosed with ETT following laparoscopic-assisted vaginal hysterectomy. Postoperative evaluation for metastatic disease was negative. The patient has been closely followed and remains disease free 8 months postoperatively. ETT presents a diagnostic challenge due to its rarity and histologic resemblance to other pathologies. ETT is relatively chemoresistant and managed surgically. Misdiagnosis delays effective treatment and affects survival

Malignant Transformation of a Mature Cystic Ovarian Teratoma into Thyroid Carcinoma, Mucinous Adenocarcinoma, and Strumal Carcinoid: A Case Report and Literature Review

Malignant transformation of a mature cystic teratoma (MCT) is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a), mucinous adenocarcinoma (b), and strumal carcinoid tumor (c)—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a). Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b). Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c)
