This retrospective study of 23 ovarian clear cell carcinoma patients found a 69.5% three-year survival rate and noted that 26.1% had associated endometriosis, highlighting distinct clinical behavior.

This retrospective study evaluated the clinical characteristics and survival outcomes of 23 patients diagnosed with ovarian clear cell carcinoma between 1993 and 2001. The cohort consisted primarily of women at early-stage disease, with all patients undergoing cytoreductive surgery followed by postoperative chemotherapy. While the overall three-year survival rate was 69.5%, the authors noted that predictors of survival require further investigation through larger randomized studies. Relevance to endometriosis: The paper explicitly mentions that 26.1% of the patients had associated endometriosis, a known risk factor for this specific histologic subtype of ovarian cancer.

Abstract

Objective : The aim of this study is to evaluate the clinical characteristics of clear cell carcinoma of the ovary. Methods : Between 1993 and 2001, 23 patients with clear cell carcinoma of ovary treated in the department of obstetrics and gynecology, Catholic University Medical College were identified and reviewed retrospectively for patient profiles, International Federation of Gynecologists and Obstetricians (FIGO) disease stage, mode of therapy, and length of survival. Results : Median age was 47 years (range 36-68 years). Tumors were 609%0 (14/23) stage I, 4.31% (1/23) stage II, 35.28% (8/23) stage III. All patients presented with a pelvic mass ranging in size from 5 cm to 27 cm. Of the patients with clear cell carcinoma, six (26.1%) had associate d endometriosis. All patients underwent cytoreductive surgery followed by postoperative chemotherapy. The median follow up for surviving patients is 48.15 months (range 0.9 to 95.4 months). The overall 3-year survival rates were 69.5%. The survival was 38.6 months. Conclusion : Clear cell carcinoma of the ovary is intriguing histologic type of epithelial cancer and demonstrates a clinical behavior distinctly different from that of other epithelial ovarian cancer. Predictors of survival for patients with clear cell carcinoma of the ovary needs to be further investigated by randomized large number study.

Abstract

OBJECTIVE The aim of this study is to evaluate the clinical characteristics of clear cell carcinoma of the ovary.

Methods

Between 1993 and 2001, 23 patients with clear cell carcinoma of ovary treated in the department of obstetrics and gynecology, Catholic University Medical College were identified and reviewed retrospectively for patient profiles, International Federation of Gynecologists and Obstetricians (FIGO) disease stage, mode of therapy, and length of survival.

Results

Median age was 47 years (range 36-68 years). Tumors were 60.9% (14/23) stage I, 4.31% (1/23) stage II, 35.28% (8/23) stage III. All patients presented with a pelvic mass ranging in size from 5 cm to 27 cm. Of the patients with clear cell carcinoma, six (26.1%) had associated endometriosis. All patients underwent cytoreductive surgery followed by postoperative chemotherapy. The median follow up for surviving patients is 48.15 months (range 0.9 to 95.4 months). The overall 3-year survival rates were 69.5%. The survival was 38.6 months.

Conclusion

Clear cell carcinoma of the ovary is intriguing histologic type of epithelial cancer and demonstrates a clinical behavior distinctly different from that of other epithelial ovarian cancer. Predictors of survival for patients with clear cell carcinoma of the ovary needs to be further investigated by randomized large number study.
