Introduction: Multiple primary tumors (MPTs) are defined as two or more separate synchronous or metachronous neoplasms occurring in different sites in the same individual. These tumors differ in histology, as well as primary sites from which they arise. Risk factors associated with the occurrence of MPTs include germline alterations, exposure to prior cancer therapies, occupational hazards, and lifestyle and behavioral influences. Case report: We present a case of a patient who was diagnosed with four metachronous primary tumors...

REVIEW
Allison A Gockley, Kevin M Elias
Ovarian cancer remains the leading cause of gynecologic cancer death among American women. Prevention is the only proven approach to reduce the incidence of the disease. Oral contraception, tubal ligation, and risk-reducing salpingo-oophorectomy (rrBSO) for high-risk groups are all established risk reduction strategies. This paradigm is changing as recent biologic studies suggest that many ovarian cancers, especially high-grade serous ovarian cancers, originate in the distal end of the fallopian tube rather than the ovarian surface epithelium...

RATIONALE: Multiple primary malignancies can occur in the same organ or in multiple organs or systems. Likewise, they can occur simultaneously or successively. Based on the timing of the diagnosis, they are classified as multiple synchronous (i.e., concurrent) or metachronous (i.e., successive) primary malignancies. The vast majority of patients have multiple metachronous malignant tumors; multiple synchronous tumors are rare. PATIENT CONCERNS: A 63-year-old woman presented with the chief complaint of vaginal fluid discharge for 3 months and abdominal pain for 1 month...

Skene's (periurethral) gland adenocarcinoma is very rare, with only 7 cases reported in the literature. This is the first series of cases on this entity. We describe the histologic, immunohistochemical, and clinical findings of 4 patients with Skene's gland adenocarcinoma retrieved from the Johns Hopkins Urologic Pathology Consult Service from 1984 to 2017. The average age at diagnosis of the 4 women was 74.5 years (range, 61 to 87 y). Tumors were treated by limited resections with negative margins. Tumor size ranged from 1...

Ovarian carcinoma histotypes are critical for research and patient management and currently assigned by a combination of histomorphology +/- ancillary immunohistochemistry (IHC). We aimed to validate the previously described IHC algorithm (Calculator of Ovarian carcinoma Subtype/histotype Probability version 3, COSPv3) in an independent population-based cohort, and to identify problem areas for IHC predictions. Histotype was abstracted from cancer registries for eligible ovarian carcinoma cases diagnosed from 2002 to 2011 in Alberta and British Columbia, Canada...

Serous tubal intraepithelial carcinoma (STIC) is found in 10% to 60% of cases of tuboovarian high-grade serous carcinoma (HGSC) and is presumed to be the site of origin, linking many HGSCs to the fallopian tube. Bilateral STIC is present in ∼20% of cases. Because clonal Tp53 mutations are a defining feature of HGSC, including their associated STICs, we analyzed 4 cases of bilateral serous tubal intraepithelial neoplasia (STIN), including STIC and Tp53-mutated serous tubal intraepithelial lesions (STILs), associated with HGSC to determine whether they contained the same or different p53 mutations...

Histopathological image analysis of stained tissue slides is routinely used in tumor detection and classification. However, diagnosis requires a highly trained pathologist and can thus be time-consuming, labor-intensive, and potentially risk bias. Here, we demonstrate a potential complementary approach for diagnosis. We show that multiphoton microscopy images from unstained, reproductive tissues can be robustly classified using deep learning techniques. We fine-train four pretrained convolutional neural networks using over 200 murine tissue images based on combined second-harmonic generation and two-photon excitation fluorescence contrast, to classify the tissues either as healthy or associated with high-grade serous carcinoma with over 95% sensitivity and 97% specificity...

We are reporting a case of endometrial lymphoepithelioma-like carcinoma (LELC) in a 63-year-old female. Microscopically, the tumor consisted of groups of tumor cells surrounded by dense lymphoplasmacytic infiltrate. Immunohistochemically, the tumour cells were positive for cytokeratins AE1/AE3, EMA, PAX8, p16, and estrogen receptors. Protein p53 showed an aberrant type of expression. Molecular genetic analysis revealed mutations in the TP53 and PIKP53CA genes. Based on our results, we believe that the tumor represents an unusual morphological variant of endometrial serous carcinoma...

Ovarian cancer is the most lethal of all common gynaecological malignancies in women worldwide. Ovarian cancer comprises of >15 distinct tumor types and subtypes characterized by histopathological features, environmental and genetic risk factors, precursor lesions and molecular events during oncogenesis. Recent studies on gene signatures profiling of different subtypes of ovarian cancer have revealed significant genetic heterogeneity between and within each ovarian cancer histological subtype. Thus, an immense interest have shown towards a more personalized medicine for understanding the clinical and molecular complexities of four major types of epithelial ovarian cancer (serous, endometrioid, clear cell, and mucinous)...

OBJECTIVE: To evaluate the role of 30-day readmission rate as a quality of care metric in patients undergoing ovarian cancer surgery. METHODS: We performed a retrospective cohort study of women diagnosed between 2004 and 2013 with advanced-stage, high-grade, serous carcinoma who underwent primary treatment. Using the National Cancer Database, we compared the performance of hospital risk-adjusted 30-day readmission rate to other quality of care metrics (risk-adjusted 30- and 90-day mortality, rates of adherence to guideline-based care, and overall survival) within hospitals categorized by yearly case volume (10 or less, 11-20, 21-30, and 31 cases per year or more)...

Aberrant methylation of multiple promoter CpG islands could be related to the biology of ovarian tumors and its determination could help to improve treatment strategies. DNA methylation profiling was performed using the Methylation Ligation-dependent Macroarray (MLM), an array-based analysis. Promoter regions of 41 genes were analyzed in 102 ovarian tumors and 17 normal ovarian samples. An average of 29% of hypermethylated promoter genes was observed in normal ovarian tissues. This percentage increased slightly in serous, endometrioid, and mucinous carcinomas (32%, 34%, and 45%, respectively), but decreased in germ cell tumors (20%)...

High-grade serous ovarian carcinoma (HGSOC) is one of the most lethal gynecologic malignancies. Currently, anti-angiogenesis therapy is the most promising strategy for the successful treatment of HGSOC. In this study, we found Neferine could inhibit the angiogenesis of ovarian cancer cells both in vitro and in vivo. Further analysis revealed that its suppressive effect on human umbilical vein endothelial cell (HUVEC) proliferation correlated with promoting cell cycle arrest and autophagy. The cell cycle genes were dose-dependently reduced and the level of LC3II/LC3I (microtubule associated protein 1 light chain 3) was increased...

A xenobank of patient-derived (PDX) ovarian tumor samples has been established consisting of tumors with different sensitivity to cisplatin (DDP), from very responsive to resistant. As the DNA repair pathway is an important driver in tumor response to DDP, we analyzed the mRNA expression of 20 genes involved in the nucleotide excision repair, fanconi anemia, homologous recombination, base excision repair, mismatch repair and translesion repair pathways and the methylation patterns of some of these genes. We also investigated the correlation with the response to platinum-based therapy...

The clear cell (CCC), high grade serous (HGSC) and endometrioid (EC) ovarian carcinomas share overlapping histological features. The oncogene IMP3 is implicated in CCC with an elusive utility in differential diagnosis. We collected 366 cases with ovarian primary carcinomas to detect IMP3, Napsin-A and HNF-1β by immunochemistry. In 351 cases, the positive expression rate of IMP3 in CCC was significantly higher than that either in EC or HGSC (p < 0.01). The sensitivity of IMP3 in CCC was higher than Napsin-A but lower than HNF-1β (p < 0...
