Summary

The aim of these studies is to study the natural history, the symptoms of, as well as the effect of hysteroscopic resection of endometrial polyps. Furthermore, another aim is to study new diagnostic techniques to differentiate between malignant and benign endometrial polyps.

Detailed description

Study Part 1: New diagnostic methods for the prediction of malignancy in endometrial polyps: A prospective pilot study. Study of angiogenesis by identification of specific angiogenesis factors in tissue biopsies from the endometrium and by Doppler ultrasound combined with IV contrast. We hope to find specific characteristics with new vessel formation in the endometrial polyp, which can play a role in the prognostic evaluation regarding the risk for cancer development. We will compare women with endometrial polyps and women with endometrial cancer to see if these methods of angiogenesis evaluation may be useful in separating benign polyps from premalignant and malignant polyps. Study Part 2: The natural history of endometrial polyps. A prospective randomised study of patients with endometrial polyps. Blood loss during menstruation is documented with the help of a standardized form (PBAC). The patients are randomized to hysteroscopic resection of the endometrial polyp or 6 months of observation. A new registration of blood loss during menstruation is performed by patients in both groups. In the intervention group, a new gynaecological examination 6 months after the resection documents the presence of residual polyp or symptoms. The other group is examined again after 6 months of observation. Symptoms and findings with the second examination are compared with symptoms and findings at the first examination, any changes are documented and the final outcome in the to groups are compared. Study Part 3: The occurrence and natural history of asymptomatic endometrial polyps in perimenopausal women. A prospective controlled study. Registration of blood loss during menstruation is documented with the help of a standardized form (PBAC) and gynaecological examination including SIS of 1000 randomly selected women in the age group 45-50. Where endometrial polyps are identified, we document the size and number of polyps and an endometrial biopsy is taken. After including a woman with an endometrial polyp in the study, the next woman without endometrial polyp is recruited to the control group. After one year, blood loss during menstruation is registered again, and all women with endometrial polyps as well as the control group have a new examination including vaginal ultrasound, SIS and endometrial biopsy. Symptoms and findings are compared with symptoms and findings at the first examination and all changes are documented. If the woman has a persistent endometrial polyp when examined at 1 year, she is offered treatment with hysteroscopic polyp resection.
