Prognostic analysis of ovarian cancer associated with endometriosis

Clinical Outcomes of Patients with Clear Cell and Endometrioid Ovarian Cancer Arising in Endometriosis

“…In this study, patients with cancer arising from endometriosis were diagnosed at an earlystage, which were consistent result with previous literatures [2,[18][19][20]. The reason for diagnosis of early-stage could be due to the signs and symptoms related endometriosis (such as pelvic pain and adnexal mass) or concurrent presences of endometrial lesions (polyps, hyperplasia) that lead to frequent follow-ups.…”

“…The Van Gorp classification provides broad ranging criteria that emphasize identification of endometriosis alone or at any transition point within the surgical specimen coexisting with EOC [3]. The Sampson and Scott criteria apply strict histologic conditions for diagnosis of cancer arising from endometriosis based on demonstration of malignant transformation in the endometriosis glands leading to EOC [18,23]. This study applied the Sampson and Scott criteria for analysis.…”

“…A number of studies have presented the tendency of patients with endometriosis to be diagnosed at a younger age, with earlier stage and lower grade lesions, and to have better survival outcomes [10][11][12][13]. However, other studies fail to demonstrate survival differences between groups with and without endometriosis [14,15] or the significance of association with endometriosis as an independent prognostic factor [16][17][18].…”

Role of endometriosis as a prognostic factor for post‑progression survival in ovarian clear cell carcinoma

“…Some reports have shown negative correlation of endometriosis with prognoses in CCC (9)(10)(11), and other investigations have shown positive association with better prognoses (12)(13)(14)(15). So the clinical impact of the complication with endometriosis in upon prognosis of CCC has not been determined.…”

Diagnostics and Therapy for Malignant (Degenerate) Colon Endometriosis – Three Case Reports

“…This was the reason in our case 2 for the adjuvant high-dose gestagen therapy for the endometroid ovarian cancer stage I c. There are also discrepancies in the literature with regard to the prognosis. Some authors found no differences between endometriosis-associated and non-endometriosis-associated malignancies [14,15] while others found a better prognosis of EAM [8,16]. The relatively favourable prognosis for endometriosis-associated malignancies in comparison to primary ovarian cancer is explained, on the one hand, as a result of genetic mutations of endometriosis cells the former is pathogenetically a unique entity or, on the other hand, clinically that many carcinomas are diagnosed and treated in the early stages.…”
