INTRODUCTION
Many advances in the understanding of the pathologic and molecular features of endometrial cancer have occurred since the FIGO staging was last updated in 2009. Substantially more outcome and biological behavior data are now available regarding the several histological types. Molecular and genetic findings have accelerated since the publication of The Cancer Genome Atlas (TCGA) data and provide improved clarity on the diverse biological nature of this collection of endometrial cancers and their differing prognostic outcomes. The goals of the new staging system are to better define these prognostic groups and create substages that indicate more appropriate surgical, radiation, and systemic therapies.
METHODS
The FIGO Women's Cancer Committee appointed a Subcommittee on Endometrial Cancer Staging in October 2021, represented by the authors. Since then, the committee members have met frequently and reviewed new and established evidence on the treatment, prognosis, and survival of endometrial cancer. Based on these data, opportunities for improvements in the categorization and stratification of these factors were identified in each of the four stages. Data and analyses from the molecular and histological classifications performed and published in the recently developed ESGO/ESTRO/ESP guidelines were used as a template for adding the new subclassifications to the proposed molecular and histological staging system.
RESULTS
Based on the existing evidence, the substages were defined as follows: Stage I (IA1): non-aggressive histological type of endometrial carcinoma limited to a polyp or confined to the endometrium; (IA2) non-aggressive histological types of endometrium involving less than 50% of the myometrium with no or focal lymphovascular space invasion (LVSI) as defined by WHO criteria; (IA3) low-grade endometrioid carcinomas limited to the uterus with simultaneous low-grade endometrioid ovarian involvement; (IB) non-aggressive histological types involving 50% or more of the myometrium with no LVSI or focal LVSI; (IC) aggressive histological types, i.e. serous, high-grade endometrioid, clear cell, carcinosarcomas, undifferentiated, mixed, and other unusual types without any myometrial invasion. Stage II (IIA): non-aggressive histological types that infiltrate the cervical stroma; (IIB) non-aggressive histological types that have substantial LVSI; or (IIC) aggressive histological types with any myometrial invasion. Stage III (IIIA): differentiating between adnexal versus uterine serosa infiltration; (IIIB) infiltration of vagina/parametria and pelvic peritoneal metastasis; and (IIIC) refinements for lymph node metastasis to pelvic and para-aortic lymph nodes, including micrometastasis and macrometastasis. Stage IV (IVA): locally advanced disease infiltrating the bladder or rectal mucosa; (IVB) extrapelvic peritoneal metastasis; and (IVC) distant metastasis. The performance of complete molecular classification (POLEmut, MMRd, NSMP, p53abn) is encouraged in all endometrial cancers. If the molecular subtype is known, this is recorded in the FIGO stage by the addition of "m" for molecular classification, and a subscript indicating the specific molecular subtype. When molecular classification reveals p53abn or POLEmut status in Stages I and II, this results in upstaging or downstaging of the disease (IICm or IAm ).
SUMMARY
The updated 2023 staging of endometrial cancer includes the various histological types, tumor patterns, and molecular classification to better reflect the improved understanding of the complex nature of the several types of endometrial carcinoma and their underlying biologic behavior. The changes incorporated in the 2023 staging system should provide a more evidence-based context for treatment recommendations and for the more refined future collection of outcome and survival data.

UNLABELLED
Vulvar lichen sclerosus is a chronic inflammatory disease involving vulvar skin. The risk of developing invasive vulvar cancer for women with LS is reported in the literature, but the risk of extra-vulvar tumors has been under-investigated. This multicentric study aims to estimate the risk of developing cancers in a cohort of women with a diagnosis of vulvar lichen sclerosus.
METHODS
A cohort of women diagnosed with and treated for vulvar lichen sclerosus in three Italian gynecological and dermatological clinics (Turin, Florence, and Ferrara) was retrospectively reviewed. Patient data were linked to cancer registries of the respective regions. The risk of subsequent cancer was estimated by dividing the number of observed and expected cases by the standardized incidence ratio.
RESULTS
Among 3414 women with a diagnosis of vulvar lichen sclerosus corresponding to 38,210 person-years of follow-up (mean 11.2 years) we identified 229 cancers (excluding skin cancers and tumors present at the time of diagnosis). We found an increased risk of vulvar cancer (standardized incidence ratio = 17.4; 95 % CL 13.4-22.7), vaginal cancer (standardized incidence ratio = 2.7; 95 % CL 0.32-9.771), and oropharyngeal cancer (standardized incidence ratio = 2.5; 95 % CL 1.1-5.0), and a reduced risk of other gynecological tumors (cervical, endometrial, ovarian) and breast cancer.
CONCLUSIONS
Patients with vulvar lichen sclerosus should undergo annual gynecological check-up with careful evaluation of the vulva and vagina. The increased risk of oropharyngeal cancer also suggests the need to investigate oropharyngeal cavity symptoms and lesions in patients with vulvar lichen sclerosus.

Pathologies of the vagina are important causes of symptoms related to the genital tract in women. They can be missed on transabdominal ultrasonography (USG), which is the baseline modality used for evaluation of gynaecological complaints. Transperineal USG and MRI are the imaging modalities of choice for evaluation of the vagina. Diseases of the vagina can be grouped depending upon the age group in which they occur. In children and young adults, congenital anomalies like longitudinal or transverse vaginal septum, imperforate hymen, vaginal aplasia or atresia, and rectovaginal fistula can be seen. Malignant tumours can rarely occur in children, rhabdomyosarcoma being the most common one. Common diseases affecting adults include benign lesions like epidermoid, Gartner duct, and Bartholin cysts, and urogenital fistulas involving the vagina. Endometriosis and other benign tumours of vagina including leiomyoma, fibroepithelial polyp, and angiomyxoma are occasionally seen. Malignant tumours can be primary, the most common one being squamous cell carcinoma, or secondary, due to direct extension from cancers involving the adjacent organs. Characteristic morphological changes occur in the vagina after radiotherapy, which can be identified on imaging. Knowledge about the imaging appearances of these diseases is crucial in guiding appropriate management.

Adenoid cystic carcinoma (ACC) is a rare neoplasm most frequently observed in the salivary glands, that can occur in other organs, including the vulva and vagina. Oncogenic mechanisms involving MYB, NFIB, and MYB-NFIB rearrangements have been described, but evidence in the vulva and vagina remains scarce. Our aim is to report the clinicopathologic features, immunohistochemical, and molecular findings in a series of vulvar and vaginal ACCs. Five cases were included. Medical records and slides were reviewed. Formalin-fixed paraffin-embedded material was available in 4 cases, where additional immunohistochemical and molecular studies were carried out. Fluorescence in situ hybridization using MYB, MYBL1, and NFIB bacterial artificial chromosome-clones break-apart and MYB::NFIB BAC-clones fusion probes was performed. The patients' mean age at diagnosis was 52 years. Tumor size ranged from 0.5 to 5 cm. Microscopic examination revealed tubular, cribriform, and solid patterns. Perineural invasion was seen in 4 cases. Patients were treated with surgery, some with adjuvant radiation therapy. During follow-up (mean: 11 yr), 4 patients developed local recurrences. Recently, one of these patients developed pulmonary disease. Cam 5.2, CK5/6, CD117, and DOG-1 were positive in all 4 cases and S100 and calponin were positive in 3 cases. MYB rearrangement was present in 3 cases, including one with concurrent MYB amplification. There were no MYBL1 or NFIB rearrangements and no MYB::NFIB fusions. Our findings corroborate that the histologic, immunohistochemical, and oncogenic background is similar between ACCs of the lower female genital tract and ACCs elsewhere, although the canonical MYB::NFIB fusion seems to be a less common finding in this location.

OBJECTIVE
To compare clinical and pathologic characteristics of women with surgical stage I endometrial carcinoma by location of first recurrence and describe characteristics of isolated vaginal recurrence.
METHODS
Patients with 2009 International Federation of Obstetrics and Gynecology (FIGO) stage I endometrial carcinoma treated at two large cancer centers from 1/1/2009-12/31/2017 were identified. Sarcoma histology was excluded. Recurrences were grouped into isolated vaginal or extravaginal. Isolated vaginal recurrences were localized by anatomic location within the vaginal vault. Clinical and pathologic variables were compared with chi-square analysis, and Kaplan-Meier curves with log-rank tests.
RESULTS
Of 2815 women identified, 278 (10%) experienced a recurrence. Sixty-one patients (2%) had an isolated vaginal recurrence, including 42 (69%) at the vaginal apex; 217 (8%) had an extravaginal recurrence, including 18 with a vaginal component. Median time to recurrence was 11 months (range, 1-68) for isolated vaginal recurrence and 20 months (range, 1-98) for extravaginal recurrence (P < .004). Of 960 patients (34%) treated with adjuvant vaginal brachytherapy (VBT), 156 (16%) recurred; 19 (2%) had an isolated vaginal recurrence, including 16 (84%) at the vaginal apex. Three-year PFS rates for isolated vaginal recurrence were 97.6% (SE ± 0.4%) with minimally invasive surgery (MIS) versus 96.9% (SE ± 1.1%) with open (P = .8), and for extravaginal recurrence were 91.8% (SE ± 0.7%) with MIS versus 90.8% (SE ± 1.8%) with open (P = .8).
CONCLUSIONS
Isolated vaginal recurrences in stage I endometrial cancer are detected earlier than non-vaginal recurrences. Surgical approach does not appear to impact recurrence. Adjuvant VBT after primary surgery carries a 1%-2% risk of isolated vaginal apex recurrence.

BACKGROUND
Carcinoma cervix is the fourth most commonly diagnosed cancer worldwide, with an estimated 604,000 new cases and 342,000 deaths worldwide in 2020. Carcinoma cervix is an uncommon malignancy in Kashmir. In this retrospective study, we have tried to find clinicopathological characteristics of carcinoma cervix along with the survival rates at our tertiary care hospital.
MATERIALS AND METHODS
Case records of cervical cancer patients registered from January 1, 2015, to January 1, 2019, were retrieved. A total of 138 patients was registered. 22 had undergone surgery, and out of these 17 had received postoperative radiotherapy. 109 patients were treated with definitive chemoradiation and 13 with palliative radiotherapy. Descriptive statistics were used to summarize patient and treatment-related variables, and Kaplan-Meier analysis was performed for survival analysis.
RESULTS
A total of 138 cases that were registered from 2015 to 2019 were included in this study. The median age at the presentation was 56 years. Most of the patients had a performance status of 1 (98 patients (71.01)). Most of the patients 110 (79.71%) were married before 20 years of age, only 1 patient was unmarried, and 85 (61.59) patients were multiparous in our study group. Only 14 (10.14%) patients in our study group had a history of oral contraceptive use and most of them were non-smokers [124 (89.80%)]. Multiple marriages were present in 8 (5.79%) patients only. The most common presenting symptom was bleeding per vagina (78.26%), and the maximum number of patients fall in the post-menopausal group (67.39%). 116 patients had squamous cell carcinoma histology while 10 patients had adenocarcinoma histology. Most of the patients had stage II and stage III disease (85 patients). At last, follow up out of 138 patients 75 (54.35) were alive. 3 year disease-free survival was 54.34% and 3-year overall survival was 72.46%.
CONCLUSION
Carcinoma cervix is an uncommon malignancy in Kashmir because of different socio-cultural and religious practices but the response to treatment, toxicity profile, and survival are similar to the rest of the world.
