The role of 18F-FDG PET/CT-based quantitative metabolic parameters in patients with ovarian clear cell carcinoma.

CONCLUSIONS: 18F-FDG PET/CT-based metabolic volumetric parameters might be predicators for survival in ovarian CCC patients. Cautions should be taken when interpreting the results due to the small sample size. PMID: 31796665 [PubMed - as supplied by publisher]

AbstractOvarian clear cell carcinoma (OCCC), with unique clinical and molecular characteristics compared with other histological types of epithelial ovarian cancer (EOC), behaves like a distinct entity and has a poorer prognosis than other EOC types, especially in advanced stages. In addition, OCCC comprises approximately 27% of all EOC cases in Japan, compared with 12% in Western countries. Historically, patients with OCCC have been eligible for chemotherapeutic and surgical trials of EOC. It has been difficult to evaluate the specific impact of these trials on the prognosis of women with OCCC because of its rarity and un...

Gynecologic clear cell carcinoma is a rare histology, accounting for ~5% of all ovarian and endometrial cancers in the United States. Compared to other types of gynecologic cancer, they are generally less responsive to standard therapy and have an overall worse prognosis. In addition, mounting evidence suggests that the landscape of genetic and molecular abnormalities observed in these tumors is distinct from other cancers that arise from the same sites of origin. On a molecular level, these tumors characteristically display upregulation of the PI3K-AKT-mTOR and RAS-RAF-MAPK signaling axes, frequent loss of ARID1a, and ove...

In conclusion, adjuvant nonpaclitaxel chemotherapy and laparoscopic tumor spillage before the staging operation did not worsen the outcome in stage IC OCCC. Positive washing cytology has a negative effect on PFS but not on OS.

In this study, we have analyzed a prospective cohort of 502 early-stage OCs to investigate their frequency, immunohistochemical characteristics, and survival of the 5 main histologic types. Histotype was assigned according to not only the morphologic features but also according to the expression pattern of WT1, p53, Napsin A, and progesterone receptors. In addition, an extended panel including p16, β-catenin, HER2, Arid1A, HINF1B, CK7, CDX2, and CK20 was used to refine the diagnosis in difficult cases. In this series, the frequency of the 5 major histologic types was as follows: endometrioid carcinoma, 32.7%; clear ce...

CONCLUSIONS: Our data show that MSI is present in a substantial proportion of endometrioid ovarian cancers but can also occur in other tumor subtypes. MMR deficiency/MSI typically involves the entire tumor mass, suggesting that MMR inactivation occurs early in tumorigenesis in a subset of ovarian cancers.

Brain metastasis is a rare and generally late manifestation of an advanced-stage, high-grade serous ovarian carcinoma. Nowadays, the improved control of intra-abdominal disease by surgery and platinum-based chemotherapy results in a longer survival, allowing distant metastasis to implant and grow in the brain parenchyma. Herein, we describe a unique case of a cerebellar metastasis from clear cell ovarian carcinoma that initially presented as a FIGO Stage IC cancer. Surprisingly, 6 mo after surgery, the patient was in good condition with complete disappearance of symptoms and no evidence of recurrence. This relativel...

Abstract BACKGROUND/PURPOSE: Ovarian clear cell carcinoma (OCCC) with recurrence/progression after treatment has dismal prognosis. We aimed to investigate the management and outcomes of such patients. METHODS: OCCC patients who were treated between 2000 and 2013 with cancer recurrence or progression after primary treatment were analyzed. Univariate and multivariate analyses were used to identify the independent predictors of survival after recurrence (SAR) and cancer-specific survival (CSS). RESULTS: A total of 64 patients experienced treatment failure (49 recurred after remission and 15 progressed witho...

ConclusionsEndometriosis is not independently associated with the prognosis of OEC and OCCC among young patients. The intrinsic relationship between endometriosis and ovarian cancer warrants further investigation.
