Overview
The majority of cases of endometrial hyperplasia (except complex atypical hyperplasia) resolve spontaneously with time.
Natural History
- The majority of cases of endometrial hyperplasia (except complex atypical hyperplasia) resolve spontaneously with time.[1][1]
- If left untreated, 30% of patients with atypical hyperplasia may progress to develop endometrial carcinoma.[2]
- Malignant transformation into endometrial cancer is the most common complication of endometrial hyperpasia.[3]
- Prognosis is generally good with treatment.
- Hyperplasia without atypia tends to spontaneously regress.
- Atypical hyperplasias are more likely to progress
- Endometrial carcinoma with concomitant hyperplasia is associated with less aggressive disease.
- When an endometrial biopsy or curettage specimen is diagnosed as atypical hyperplasia, the risk of concomitant carcinoma in the same uterus has been reported as 17% to 25% (35–37).
- On the contrary, 2 recent studies have concluded that the concomitant presence of carcinoma in uteri sampled for endometrial hyperplasia is considerably higher.[4]
- Adenocarcinomas arising from an atypical hyperplasia are of the endometrioid cell type, whereas those developing from an atrophic endometrium may be either endometrioid or non-endometrioid cell type.
- Endometrioid adenocarcinomas arising through the hyperplasia-neoplasia sequence are oestrogen induced.
- Well differentiated
- Less invasive of the myometrium
- Lack lymphatic and metastatic involvement
- Excellent prognosis.
- Oestrogen-induced adenocarcinomas are also endometrioid, arising from an atrophic or a rather weakly proliferating endometrium.
- Frequently of higher histological grade
- Less favourable prognosis.
- Finally, endometrial carcinomas of the non-endometrioid cell type, mainly serous papillary and clear cell carcinomas, are non-oestrogen induced and non-hyperplasia associated.
- Adverse aggressive histological features
- Extremely poor prognosis.[5]
- Endometrioid adenocarcinomas arising through the hyperplasia-neoplasia sequence are oestrogen induced.
Complications
- Malignant transformation is the most common complication of endometrial hyperpasia.[3]
- Complications of untreated or poorly controlled endometrial hyperplasia can be serious.
- To minimize risk of serious complications follow the treatment plan provided by health care professional designed specifically for patient.
- Complications of endometrial hyperplasia include:
- Absenteeism from work or school
- Anemia
- Cancer of the uterus
- Inability to participate normally in activities
- Infertility
- Menorrhagia
Prognosis
- Prognosis is generally good with treatment for endometrial hyperplasias without atypia.
- Chronic anovulation, obesity, polycystic ovarian syndrome, metabolic syndrome, insulin resistance, and type 2 diabetes mellitus must be appreciated as risk factors for endometrial pathology.
- Initiating pre-emptive strategies is highly important. This includes; risk reduction with lifestyle modification, weight loss, and glycemic control can improve regression and overall health.
- Fertility outcomes for these patients are promising, especially with assisted reproductive technology.[6]
