Distribution of malignant neoplasms among patients with endometriosis: an epidemiological study
Hypothesis/aims of study. The current analysis was undertaken to assess the incidence of malignant diseases in patients with endometriosis.
Study design, materials and methods. This is a cohort study of women with surgically verified endometriosis retrieved from the Saint Petersburg 122 Clinical Hospital Discharge Register 1996–2006 (n = 1551). Data were linked to the Saint Petersburg Cancer Agency to identify cases of malignancy.
Results. Malignant diseases were identified in 6.3% (n = 98) of cases. The median follow-up was 12.2 (7.5) years. Breast cancer (n = 29), ovarian cancer (n = 7), endometrial cancer (n = 7), thyroid cancer (n = 7), colorectal cancer (n = 6), melanoma (n = 6), non-Hodgkin’s lymphoma (n = 4), and glioblastoma (n = 3) were prevalent.
Conclusion. The incidence of cancer in patients with endometriosis is low. Women with endometriosis have an increased risk of some malignancies, particularly ovarian cancer.
