When to Worry about Cancer: Concurrent Carcinoma and Recurrence in Borderline Ovarian Tumors.

CONCLUSIONS: Epithelial borderline ovarian tumors often co-exist with carcinoma and occur more frequently in postmenopausal women, in women with elevated CA-125, and in tumors with nonserous histology. The presence of any of these factors should alert clinicians to the potential need for comprehensive staging at the time of surgery. The recurrence of borderline tumors is associated with nonwhite race, concurrent carcinoma, and residual disease at initial surgery. PMID: 31796975 [PubMed - in process]

sen K Abstract Introduction: The aim of the present study was to investigate the prognostic impact of intratumoral cytotoxic T cells, Natural Killer (NK) cells, neutrophils and PD-L1 expression in patients with epithelial ovarian cancer.Methods: All patients diagnosed with high-grade serous carcinoma (HGSC) in Denmark in 2005 were included in the study. Immunohistochemical staining for PD-L1, CD8, CD66b and CD57 was performed on tumor tissue from 283 patients. Cell densities were analyzed using a digital image analysis method. The primary endpoint was overall survival (OS).Results: The median OS for HGSC patients ...

We present a case of 50-year-old postmenopausal women who presented with coexisting incidental Brenner tumor with leiomyoma and Endometrial adenocarcinoma. Only few authors have reported similar tumor occurrence in the past.

ConclusionThese results are largely incompatible with a tumor-suppressive function of LATS in ovarian cancer, and LATS protein level is also not an indicator for drug sensitivity and EMT status of ovarian cancer cells.

Conclusions: This study provides evidence in a molecular level that ovarian low-grade serous carcinomas likely originate from the fallopian tube rather than from ovarian surface epithelia. Similar gene expression profiles among fallopian tube, ovarian epithelial inclusions, and serous tumors further support that ovarian low-grade serous carcinomas develop in a stepwise fashion. Such findings may have a significant implication for "ovarian" cancer-prevention strategies. PMID: 30949203 [PubMed]

Conclusion and clinical relevanceThe pilot study demonstrates the potential of MALDI ‐Imaging derived proteomic classifiers in combination with machine learning algorithms to discriminate EOC histotypes. Applications might support the development of new prognostic parameters in the assessment of EOC.This article is protected by copyright. All rights reserved

This study determines FLOT1 expression in human ovarian tumors and examines its effect on OC   cell proliferation. FLOT1 protein expression was assessed in a tissue microarray by immunohistochemical staining. We found that 81.48% malignant and 50% borderline tumors were FLOT1 protein-positive, whereas benign tumors and normal ovarian tissues were negative. The staining was strongest in serous malignant tumor and transitional cell carcinoma and weakest in mucinous tumor. Differentially expressed FLOT1 in freshly isolated serous tumors was confirmed by Western blot and we then evaluated FLOT1 expression association...

Publication date: Available online 25 July 2018Source: Pathology - Research and PracticeAuthor(s): In Hye Song, Kyu-Rae Kim, Sehun Lim, Seok-Hyung Kim, Chang Ohk SungAbstractThe epithelial-mesenchymal transition (EMT) is known to be associated with carcinoma invasion and metastasis. Previous studies have demonstrated that the expression of EMT-related proteins in carcinoma cells in many organs is associated with a higher histologic grade and a poor prognosis. However, the clinical significance of EMT in ovarian cancers is controversial.Formalin-fixed and paraffin-embedded tumor samples of 198 high-grade serous carcinomas (...

Conclusion: The plasma levels of septin-9 and clusterin in ovarian cancer patients were abnormally elevated, which might be used as potential candidates of peripheral blood tumor biomarkers for early diagnosis of EOC and septin-9 might be related to distal metastases of EOC. The septin-9 might play the promotion role, which protein level relates to not only the distal metastases but also the prognosis of EOC. Due to the limit of sample volume, further enlargement of the sample size and set up of the follow-up system is in need to in-depth study the relationship between plasma protein concentration with the distal metastase...

Conclusions In summary, βV-tubulin was localized to secretory cells of the distal FTE and its expression varied according to the clinical diagnosis. The frequency of these cells and thus expression of βV-tubulin were dramatically enriched in tissue obtained from BRCA mutant cases, which also exhibited pronounced histologic atypia indicative of early predysplastic aberrations. Furthermore, elevated expression of βV-tubulin correlated with poor differentiation status in serous ovarian neoplasms.

We present a brief review of possible mechanisms to account for this unusual presentation and speculate that the most likely one is exfoliation of fallopian tube epithelial cells into the peritoneal cavity, which then gain access to lymphatics resulting in cells implanting in the brain and subsequently progressing to an atypical proliferative (borderline) serous tumor.
