Management and clinical outcomes of patients with recurrent/progressive ovarian clear cell carcinoma.

Management and clinical outcomes of patients with recurrent/progressive ovarian clear cell carcinoma. J Formos Med Assoc. 2019 Dec 06;: Authors: Huang HJ, Yang LY, Tung HJ, Ku FC, Wu RC, Tang YH, Chang WY, Jung SM, Wang CC, Lin CT, Liu FY, Lin G, Chen MY, Chou HH, Chang TC, Chao A, Lai CH 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 without remission). The 5-year CSS rates of recurrent/progressive OCCC patients were 22.9% (progression group: median CSS 5.9 months [range, 0.8-25.2] vs recurrence group: 43.6 months [range, 7.1-217.8]; p

Authors: Yamagami W, Nagase S, Takahashi F, Ino K, Hachisuga T, Mikami M, Enomoto T, Katabuchi H, Aoki D Abstract OBJECTIVE: International Federation of Gynecology and Obstetrics (FIGO) staging for ovarian, fallopian tube, and peritoneal cancers was revised in 2014. The aim of this study is to clarify whether the revised FIGO2014 staging reflects the prognosis of patients with ovarian cancer by histological type in Japan. METHODS: We extracted 9,747 patients who were diagnosed with ovarian cancer since 2004 until 2008 and who could be classified into appropriate stages from the Gynecologic Cancer Registry of Ja...

Abstract OBJECTIVE: To determine incidence of ovarian clear cell cancer (OCCC) by race ethnicity and how that relationship is affected by birthplace among Asian Pacific Islanders (API). METHODS: The 18 registries of the U.S. Surveillance, Epidemiology, and End Results (SEER) dataset were queried to identify all women registered with epithelial ovarian cancer from 1973 to 2013. Relative risks of OCCC to non-OCCC based on ethnicity and birthplace were compared. RESULTS: We identified 72, 501 women with epithelial ovarian cancer in the dataset; of these, 5078 (7.0%) had OCCC and 4859 (6.7%) were API. The ag...

In conclusion, our study shows that IGF2BP3 expression is a promising biomarker for prognostication of women diagnosed with OCCC with multiple effects on key cell functions, supporting its role as an important cellular regulator with potential oncogenic activity, and as a potential target for future intervention strategies.

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.
