Mullerian cancer

Ovarian carcinosarcoma (OCS), also known as a malignant mixed Müllerian tumour (MMMT), is a rare and aggressive form of cancer that accounts for less than 5% of ovarian cancers. It is characterized by high morbidity and mortality rates, with a median overall survival (OS) of less than 2 years. Several factors, including advancing age, nulliparity, reduced lactation rates, decreased use of oral contraceptive pills, genetic mutations in BRCA (breast cancer) genes, and the use of assisted reproductive technology, may increase the risk of OCS...

AIMS: The invasive pattern in HPV-associated endocervical adenocarcinoma (HPVA) has prognostic value. Non-destructive (pattern A) HPVA has excellent prognosis mirroring adenocarcinoma in-situ (AIS). However, the rare occurrence of ovarian spread in these tumours suggests aggressiveness in a subset of patients with these otherwise indolent lesions. We hypothesise that AIS/pattern A HPVA with ovarian metastases are biologically different than metastatic destructively invasive HPVA. METHODS AND RESULTS: Samples from patients with HPVA and synchronous or metachronous metastases were retrieved and reviewed to confirm diagnosis and determine the Silva pattern in the primary lesion...

Estradiol (E2), a follicle-stimulating hormone (FSH), AMH, and inhibin B levels, along with AFC and MOV, are used to determine ovarian reserve in pre-menopausal women. Studies have shown that AMH levels are more sensitive than those of E2, FSH, and inhibin B and that AFC and MOV can be used to evaluate ovarian reserve. AMH, AFC, and MOV measurements were performed before and after adjuvant SC in 3-month periods for one year. Patients were classified as experiencing chemotherapy-induced amenorrhea (CIA) if they did not have menstrual cycles for a period of six months or longer following the conclusion of their chemotherapy treatment...

Clear cell carcinomas of Müllerian origin have a strong female predominance and only extremely rarely will arise within the kidney, presumably due to ectopic Müllerian embryogenesis. Herein, we report a unique case of metastatic Müllerian type clear cell carcinoma in a 37-year-old patient who had previously received a transplanted kidney from his father at age 11 (due to severe bilateral vesicoureteral reflux) and remained on chronic immunosuppression. The tumor was highly aggressive and demonstrated somatic mutations in NF2 and SETD2...

We aimed to determine the incidence, treatment regimen, and treatment outcomes (including progression-free survival and overall survival) of gynecologic carcinosarcoma, a rare, aggressive, and understudied gynecologic malignancy. This retrospective review included all patients with gynecologic cancers diagnosed and treated at a single tertiary care comprehensive cancer center between January 2012 and May 2021. A total of 2116 patients were eligible for review, of which 84 cases were identified as carcinosarcoma: 66 were uterine (5...

PURPOSE: Ovarian decortication may affect ovarian function. We investigated the status of ovarian reserve after ovarian decortication plus chemotherapy at a stage of presumed stabilized recovery in women surviving cancer. METHODS: We searched our database for cancer survivors subjected to ovarian decortication and chemotherapy at least 3 years previously. Ovarian function was explored for levels of anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol (E2), and menstrual pattern...

Juvenile granulosa cell tumors (JGCTs) are rare, though carry significant burden of morbidity and mortality. A 15-year-old menstruating female with abdominal pain was diagnosed with a large 22.3 cm pelvic mass. CA-125 and LDH were elevated. Exploratory laparotomy was undertaken due to lesion size, and left salpingo-oophorectomy with omentectomy was completed. Pathology confirmed JGCTs with focal disruption, consistent with Stage IC disease. Six weeks postoperatively, the patient experienced recurrent abdominal pain and ultrasound revealed a 7...

Although endometrial cancer is a common malignancy in women, rare histological subtypes can pose diagnostic challenges. Primary endometrial intestinal-type mucinous carcinoma is a newly recognized subtype of endometrial cancer that differs from Müllerian-type endometrial mucinous carcinoma. The present case report documents a rare case of intestinal-type mucinous carcinoma of the endometrium showing a polypoidal exophytic form. The patient, an 80-year-old female, was incidentally diagnosed with a uterine tumor during a follow-up for vulvar Paget's disease...

BACKGROUND: Better tools for post-chemotherapy amenorrhea risk assessment are needed for fertility preservation decision-making. Our aim was to determine the predictors of amenorrhea risk at 12 and 18 months post-chemotherapy in women with breast cancer. METHODS: 142 women with breast cancer were longitudinally followed for their menstrual changes at 6, 12, and 18 months after the completion of adjuvant chemotherapy with an Anthracycline-Cyclophosphamide-based (AC-based) or Cyclophosphamide-Methotrexate +5-Fluorouracil regimen...

BACKGROUND: We aimed to determine whether adding metformin to carboplatin treatment would reduce the damage to ovarian reserve associated with carboplatin use. METHODS: We included 35 adult female non-pregnant albino Wistar rats approximately three months old, weighing 220-310 g. The rats were divided into five groups of seven rats according to the treatment they received. Carboplatin and salin was given to Group 2, and carboplatin plus metformin was given to Group 3...

BACKGROUND: Single-agent chemotherapy using methotrexate or actinomycin D is the first-line treatment for patients with low-risk gestational trophoblastic neoplasia. Various methotrexate-based and actinomycin D-based single-agent regimens can be used. However, there is insufficient evidence to determine the superior regimen. To guide doctors in selecting a single-agent chemotherapy regimen for patients with low-risk gestational trophoblastic neoplasia, we will compare two regimens. METHODS: We will conduct a multicentre, randomized, prospective clinical trial...

INTRODUCTION: Reclassification of HER2-negative breast cancers to HER2 low-level expression allowed targeted anti-HER2 therapy in about 60% of patients, improving outcome. The high recurrence rates and often dismal outcomes with current therapies of high-grade Mullerian carcinomas, offers opportunity to explore anti-HER2 therapies in the gynecologic tract carcinomas. We investigated HER2 low expression as currently defined in breast carcinomas. METHODS: We reviewed all high-grade Mullerian cancers between 2016 and 2021, where HER2 by IHC and/or FISH tests were available...

OBJECTIVES: Premature ovarian failure (POF) is defined as the cessation of menstrual periods for at least 4-6 months before the age of 40 years, accompanied by FSH values measuring over 40 IU/L for a month. Radiation therapy, one of the cancer treatment methods, is known to accelerate ovarian aging by reducing and eliminating the number of primordial follicles in the ovarian follicle pool. Ionizing radiation has been reported to cause POF. The objective of this study is to investigate the impact of mesenchymal stem cell conditioned medium (hAMSCs-CM), which is isolated from the amniotic membrane of human placenta, on premature ovarian failure (POF) caused by whole-body irradiation...

PURPOSE: To evaluate the impact of treatment for Hodgkin lymphoma (HL) on clinical reproductive markers and pregnancy outcomes. METHODS: This study was embedded within the DCOG LATER-VEVO study; a Dutch, multicenter, retrospective cohort study between 2004 and 2014. Serum anti-Müllerian hormone (AMH), follicle stimulating hormone (FSH), inhibin B, antral follicle count (AFC), and self-reported (first) pregnancy outcomes were evaluated in female childhood HL survivors and controls...

OBJECTIVES: We examined the blood concentrations of carbohydrate antigen 125- Thomsen-nouveau (CA125-Tn) and anti-Müllerian hormone (AMH) in epithelial ovarian cancer (EOC) patients to evaluate their potential diagnostic utility together with CA125, human epididymis protein 4 (HE4) and Risk of Malignancy Algorithm (ROMA). DESIGN & METHODS: 50 healthy subjects, 45 EOC patients, 22 patients with borderline ovarian tumors (BOT), 21 patients with benign ovarian tumor (BET) and 45 patients with chocolate cyst of ovary (CCO) were studied...

PURPOSE OF REVIEW: We reviewed the most recent developments including the safety and effectiveness data and success rates in individualized ovarian stimulation protocols for adult and postpubertal females with cancer. RECENT FINDINGS: In women with breast cancer, aromatase inhibitor- and tamoxifen-supplemented stimulation protocols increase the margin of safety by limiting estrogen exposure. The outcomes of ovarian stimulation appear similar between cancer and noncancer populations, even with the recently developed random-start protocols, which allow initiation of ovarian stimulation anytime during the menstrual cycle...

BACKGROUND: Treatment options for premature ovarian insufficiency (POI) are limited to hormone replacement and donor oocytes. A novel induced pluripotent stem cell (iPSC) transplant paradigm in a mouse model has potential translational applications for management of POI. METHODS: Mouse ovarian granulosa cell derived-iPSCS were labelled with green fluorescent protein (GFP) reporter and differentiated in vitro into oocytes. Differentiated cells were assayed for estradiol and progesterone secretion by enzyme-linked immunosorbent assays...

PURPOSE: This systematic review aims to provide a data synthesis about the risk of neovaginal cancer in women with Müllerian anomalies and to investigate the association between the adopted reconstructive technique and the cancer histotype. METHODS: PubMed, MEDLINE, Embase, Scopus, ClinicalTrials.gov and Web of Science databases were searched from inception to March 1st, 2023. Studies were included if: (1) only women affected by Müllerian malformations were included, (2) the congenital defect and the vaginoplasty technique were clearly reported, (3) the type of malignancy was specified...

Cancer-associated mesothelial cells (CAMCs) in the tumor microenvironment are thought to promote growth and immune evasion. We find that, in mouse and human ovarian tumors, cancer cells express anti-Müllerian hormone (AMH) while CAMCs express its receptor AMHR2, suggesting a paracrine axis. Factors secreted by cancer cells induce AMHR2 expression during their reprogramming into CAMCs in mouse and human in vitro models. Overexpression of AMHR2 in the Met5a mesothelial cell line is sufficient to induce expression of immunosuppressive cytokines and growth factors that stimulate ovarian cancer cell growth in an AMH-dependent way...

Anti-Müllerian hormone (AMH) is produced and secreted by granulosa cells of growing follicles, and its main role is to inhibit the recruitment of primordial follicles, reduce the sensitivity of follicles to follicle stimulating hormone (FSH) and regulate FSH-dependent preantral follicle growth. It has become an effective indicator of ovarian reserve in clinical practice. Research on AMH and its receptors in recent years has led to a better understanding of its role in breast cancer. AMH specifically binds to anti-Müllerian hormone receptor II (AMHRII) to activate downstream pathways and regulate gene transcription...
