In recent years the incidence in endometrial cancer is rising. The relation of cervical to endometrial cancer has shifted to almost 1:1. The peak of age distribution is between 50 and 60 years of age. Accompanying diseases are obesity, diabetes and hypertension. The endometrial cancer has its precancerous stages. The pertinent estrogenic stimulus is probably significant for the development of precancerous lesions: adenomatous hyperplasia of the endometrium without atypias is known as an optional, that with atypia as an obligatory precancerous lesion. The range of morphologic variation extends from mature endometrial adenocarcinoma with favorable prognosis to immature neoplasias with unfavorable outcome. Besides various other parameters of neoplastic disease the depths of infiltration into the myometrium is known to be significant. The leading sign of endometrial cancer is uterine bleeding. The histological diagnosis is established by the examination of the tissue produced by curettage from the cervical canal and from the uterine cavity. A true early diagnosis--in comparison to the early detection of cervical cancer--does still not exist for endometrial cancer. Exfoliative cytology from the uterine cavity or ultrasonography does still not allow the final and definite diagnosis. Among the therapeutic alternatives abdominal hysterectomy in combination with bilateral adnexectomy plays the most important role. Depending from more specific morphologic criteria of a given case additional pelvic and paraaortic lymphnode-dissection is advised. Surgical therapy in general accounts for a 10 to 20 percent better survival. In patients who cannot surgically be treated because of the local extension of the tumor or due to a general high risk situation the primary therapy is pelvic irradiation both by packing and percutaneously. Disseminated neoplasms, adenocarcinomas in particular, respond well to large dosages of progestins, whereas combinations of cytostatics have failed to show favorable results, perhaps with the exception of those containing adriamycin. All endometrial cancer patients need special posttreatment care, because early recurrences still have a certain chance of survival when recognized and appropriately treated.

All cases of endometrial adenocarcinoma treated at the Geisinger Medical Center from January 1970 to June 1980 were retrospectively reviewed in an attempt to elucidate the clinical and pathologic profiles of the various histologic subtypes. Complete clinical and pathologic data was available in 418 cases of stage I endometrial adenocarcinoma. The frequency of the histologic subtypes were adenocarcinoma 66%, adenoacanthoma 16%, adenosquamous 5%, papillary 8%, clear cell 3%, and secretory 2%. Absolute 5-year survival was adenocarcinoma 88%, adenoacanthoma 91%, adenosquamous 62%, papillary 63% (P less than 0.01), clear cell 43% (P less than 0.001), and secretory 89%. When comparing the clinical and pathologic profile of the various histologic subtypes, adenosquamous (52%, P less than 0.001) and clear cell (43%, P less than 0.05) were associated with the highest percentage of grade 3 differentiation. Adenosquamous (38%, P less than 0.05) and clear cell (36%) also had the highest percentage of deep myometrial invasion. Papillary subtype (46%, P less than 0.05) was associated with the highest percentage of nulliparity. There was no difference among the subtypes when comparing menopausal status, exogenous estrogen, obesity, hypertension, diabetes, or uterine size. In summary, (1) adenocarcinoma and adenoacanthoma are the most frequent subtypes; (2) adenosquamous, papillary, and clear cell have decreased 5-year survival; (3) the decreased 5-year survival in adenosquamous and clear cell subtypes appears to be associated with increased grade 3 differentiation and deep myometrial invasion while the poor prognosis associated with papillary subtype was not related to grade or myometrial invasion.

All cases of endometrial adenocarcinoma from January 1970 to December 1980 treated at the Geisinger Medical Center were reviewed retrospectively. One hundred eighty-eight cases of stage I grade 2 adenocarcinoma of favorable histologic subtype (adenocarcinoma, adenoacanthoma) and limited myometrial invasion (less than one-third of the myometrium) were identified. Surgery and adjuvant radiotherapy was used in 136 cases, and 52 cases were treated with surgery alone. There was no statistically significant difference between the two groups in menopausal status, parity, exogenous estrogen, obesity, hypertension, diabetes, or uterine size. Five-year survival for the surgery and radiotherapy group was 94% (128 of 136), and the recurrence rate was 2.2% (three of 136). The five-year survival for the surgery-alone group was 98% (51 of 52), and the recurrence rate was 1.9% (one of 52). There was no statistically significant difference in five-year survival or recurrence between the two groups. This study suggests that surgery alone is adequate treatment for stage I grade 2 adenocarcinoma of favorable histologic subtype and limited myometrial invasion. This study also shows a possible benefit in the combined use of histologic subtype, grade, and myometrial invasion as prognostic indicators and as guides for adjuvant radiotherapy.

In a review of 440 patients treated for endometrial adenocarcinoma at this center since 1974, 21 patients with tumors of papillary histology were identified. Eleven (2.5%) lesions contained histologic changes characteristic of uterine papillary serous carcinoma: complex papillary architecture, high nuclear/cytoplasmic ratio, and irregular epithelial tufting. Ten lesions (2.3%) containing areas of papillary morphology but lacking the criteria for the diagnosis of papillary serous tumors were termed papillary endometrioid adenocarcinoma. Patient age, stage, and the presence of obesity, hypertension, and diabetes were similar in both groups and reflected those characteristics well established for endometrial adenocarcinoma in general. Fewer papillary serous tumors (16.7%) and papillary endometrioid tumors (33.3%) contained progesterone receptors than did other adenocarcinomas (52.3%). In clinical stage I, surgical findings indicating a more advanced stage were present in 40% of patients with papillary serous tumors compared to 10% in papillary endometrioid tumors and 12.5% in nonpapillary adenocarcinomas (P = 0.03, Fisher's exact test). Recurrences were observed in 50% of patients with papillary serous lesions compared to 42.9% in papillary endometrioid lesions and 24.3% in other adenocarcinomas. Survival for clinical stage I papillary serous tumors was worse than that for nonpapillary grade 3 controls (P = 0.042) and survival for papillary endometrioid lesions was not different from that of the same controls. These findings support those of J. L. Chen, D. C. Trost, and E. J. Wilkinson (Int. J. Gynecol. Pathol. 4, 279-288 (1985)) that papillary serous and papillary endometrioid adenocarcinomas represent two distinct subtypes of papillary endometrial neoplasia.

A controlled study has been made of the constitutional background of 300 cases of endometrial adenocarcinoma. The control group was age matched and drawn from the same patient population pool as were the adenocarcinoma cases.Endometrial adenocarcinoma was shown to be associated unduly frequently with hypertension, nulliparity and the late age of menopause. No association was found between endometrial adenocarcinoma and obesity, diabetes mellitus, thyroid disease or extragenital malignant disease.It is suggested that these results are explicable on the basis that adrenal dysfunction may be an aetiological factor in the development of endometrial adenocarcinoma.

The 10-year experience at The Johns Hopkins Hospital with 61 cases of mixed Mullerian tumors were reviewed. The patients had a mean age of 63.7 years and the similar constitutional factors of diabetes mellitus, hypertension and nulliparity of endometrial adenocarcinoma. Only one patient had estrogen exposure. Eighteen percent had had prior exposure to pelvic radiation. The life table survival of the 61 patients was 41.1% at 5 years. The 2-year life table survival was 76% for disease confined to the uterus and 16.5% for extrauterine disease. There was no difference in survival between homologous and heterologous tumors. The surgical staging and the autopsies reviewed documented widely disseminated disease even when the tumor appeared to be confined to the uterus. It thus appears essential in order to improve survival these patients require aggressive staging and consideration of systemic adjuvant chemotherapy.

Excluding cases associated with oral sequential contraceptives, adenocarcinoma of the endometrium in young women is rare, constituting about 3% of endometrial carcinomas. The present report, based on findings from one institution, notes that women 40 years of age or younger comprised 14.4% of the 111 patients with adenocarcinoma of the endometrium. Factors analyzed in patients 40 years of age or younger (group A) as compared with those 41 years of age or older (group B) include the following: obesity 43.8% (A) versus 17.9% (B), nulliparity 44% (A) versus 10.5% (B), hypertension 31.2% (A) versus 42.1% (B), and diabetes 6.2% (A) versus 21.1% (B). Patients in group A tended to have a well-differentiated tumor, and 31.2% had polycystic ovaries. Awareness of risk factors in young women who develop endometrial adenocarcinoma leads to earlier diagnosis and will preserve the historically excellent survival rate of young women.

Endometrial adenocarcinoma is commonly seen in the perimenopausal and postmenopausal age groups. Certain medical conditions (such as diabetes, hypertension, and obesity) are often associated with development of this disease. Consequently, when irregular bleeding develops, a decision to sample the endometrium is often predicated on the patient's age and the presence of these associated conditions. Often, healthy young women receive empirical hormonal therapy for irregular bleeding without prior endometrial sampling. An unusual case of endometrial adenocarcinoma arising during lactation in a young healthy woman is presented.

From 1970 to 1992, 136 patients with a histologic diagnosis of endometrial hyperplasia underwent total abdominal hysterectomy at the University of Kentucky Medical Center. Slides of the curettage or biopsy specimens were reviewed and classified according to the International Society of Gynecologic Pathologists System as simple or complex endometrial hyperplasia with or without cytologic atypia. Slides of the hysterectomy specimens were likewise reviewed independently and classified according to the same system. Eighty-two patients had a preoperative diagnosis of simple or complex endometrial hyperplasia without atypia. There were no cases of occult endometrial carcinoma in the hysterectomy specimens of these patients. Simple or complex hyperplasia with atypia was present in 54 patients and endometrial adenocarcinoma was observed in 19 of these cases (35%). The International Federation of Gynecology and Obstetrics stage and histologic grade of these patients was as follows: Stage IA grade 1--5; Stage IB grade 1--10; Stage IB grade 2--1; Stage IC grade 1--1; Stage IC grade 2--1; and Stage IIIA grade 2--1. The risk of associated endometrial cancer in patients with atypical hyperplasia was independent of age, diabetes mellitus, hypertension, or the use of exogenous estrogens. All patients with endometrial cancer have been followed for 1-12 years (mean 3.0 years) after therapy and no patient has experienced tumor recurrence. These data suggest that there is a significant risk of endometrial cancer in patients with histologic evidence of atypical endometrial hyperplasia on curettage or biopsy. At the time of surgery, patients with atypical endometrial hyperplasia should have careful inspection of the uterine specimen. Any endometrial tissue suspicious for malignancy should be examined histologically, and if cancer is confirmed, complete surgical staging should be performed.

Flow-cytometric studies have demonstrated that DNA aneuploidy and proliferative activity are independent prognostic factors in endometrial carcinoma. The authors performed flow-cytometric analysis of the nuclear DNA content of 46 fresh endometrial adenocarcinomas to investigate tumor DNA ploidy and cell-cycle kinetics in relation to histologic features with known prognostic significance, mitotic activity (assessed quantitatively), and clinical features suggestive of hyperestrogenism. Thirty-five tumors (76%) were DNA-diploid, and 11 (24%) were DNA-aneuploid. DNA aneuploidy correlated significantly with two histologic features: high cytologic grade (P < .027) and five or more atypical mitoses per 50 high-power fields (P < .001). The presence of one or more atypical mitosis per 50 high-power fields, evaluated independent of DNA ploidy, was associated with stage III or IV tumors (P < .015). A low proliferative index correlated with tumors with grade 1 architecture (P < .006) and grade 1 or 2 cytology (P < .017); a high proliferative index correlated with vascular invasion by tumor (P < .027). DNA ploidy and proliferative activity did not correlate with any feature indicative of estrogenic status including age, parity, menopausal status, obesity, hypertension, diabetes, exogenous estrogen use, or endometrial hyperplasia. Therefore, in endometrial adenocarcinoma, estrogenic status does not correlate with DNA ploidy or proliferative activity; proliferative activity correlates with tumor grade; and atypical mitoses appear to be highly associated with both DNA aneuploidy and advanced tumor stage, and as such, may identify tumors with a poor prognosis.
