Comparing Surgical and Oncological Outcomes between Indocyanine Green (ICG) Sentinel Lymph Node Mapping with Routine Lymphadenectomy in the Surgical Staging of Early-Stage Endometrioid Endometrial Cancer.

Methods: A retrospective single-centre cohort study of patients with early-stage endometrioid endometrial cancer undergoing staging surgery (total hysterectomy, bilateral salpingo-oophorectomy with/without pelvic lymph node, and/or para-aortic lymph node dissection (PLND)) with either SLN mapping or routine lymphadenectomy between July 2017 and December 2018.

Results: 203 cases with clinical and radiological International Federation of Gynaecology and Obstetrics (FIGO) stage I endometrioid endometrial cancer were included, out of which 109 cases underwent SLN mapping and 94 cases complete lymphadenectomy. Compared to the PLND group, the SLN group had shorter operative time (129 vs.

Medical Management of Atypical Endometrial Hyperplasia: Oncological and Reproductive Outcomes at a Tertiary Center in Singapore.

Background Medical management of atypical endometrial hyperplasia (AEH) includes oral or intrauterine progestins. This study aims to evaluate the oncological and reproductive outcomes of these patients and the predictive factors for disease regression, as well as to compare the treatment efficacy of different forms of progestins. Methodology This retrospective study was conducted at KK Women's and Children's Hospital, Singapore.

Biallelic NF1 inactivation in high grade serous ovarian cancers from patients with neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) is a multisystem disorder caused by germline heterozygous NF1 loss-of-function variants. The NF1 gene encodes neurofibromin, a RAS GTPase-activating protein, which functions by down-regulating RAS/RAF/MAPK-signalling pathways. Somatic NF1 aberrations frequently occur in sporadic ovarian cancer (OC), but the incidence of OC in NF1 patients is rare.
