Uterine papillary serous carcinoma (UPSC) is a distinct histologic type of endometrial cancer which is associated with a high relapse rate and poor prognosis. Between 1983 and 1993, 50 patients with UPSC of the endometrium were surgically staged. Thirty-three patients had pure UPSC and 17 had UPSC admixed with other histologies. Extrauterine disease was found in 36 women (72%). Lymph node metastases were present in 36% of women without myometrial invasion, 50% with inner one-half invasion, and 40% with outer one-half invasion. Similarly, the presence of intraperitoneal disease or positive washings did not correlate with increasing myometrial invasion. Grade and histology (mixed vs pure) were also not predictive of extrauterine disease. Patients with lymphatic/vascular space invasion (LVSI) were more likely to have extrauterine disease (85%); however, even without LVSI the incidence of extrauterine disease was 58% (P = 0.05). Unlike endometrioid adenocarcinomas, grade and depth of myometrial invasion were not significant predictors for extrauterine disease. This study reinforces the need for complete surgical staging in all patients with UPSC regardless of depth of invasion.

In order to clarify the factors that affect growth of endometrial carcinoma, immunohistochemical analyses of bcl-2, p53, sex steroid receptors, and Ki-67 were performed in 35 cases of endometrial carcinoma (32 endometrioid and three clear-cell carcinomas). Correlation of antigen expression with clinicopathological features was analyzed. Expression of bcl-2 was found in 58.8, 33.3, and 20.0% of grade 1 (G1), grade 2 (G2), and grade 3 (G3) endometrial carcinomas, respectively. Estrogen receptor (ER) was observed in 70.6, 22.2, and 0% of G1, G2, and G3 cases (p < 0.01), respectively. In contrast, expression of p53 was found in 5.8, 33.3, and 60.0% of G1, G2, and G3 cases, respectively. The labeling index of Ki-67 correlated with p53 overexpression (p < 0.01). Lymph node metastases were observed in 6.6 and 5.5% of ER- and PR (progesterone receptor)-positive carcinomas, whereas metastases were observed in 44.4 and 53.3% of ER- and PR-negative carcinomas, respectively (p < 0.05). Lymph node metastases were observed in 50.0% of p53-positive carcinomas, whereas metastases were observed in 22.2% of p53-negative carcinomas (p < 0.05). These results suggest that bcl-2 expression in endometrial carcinomas is regulated in a hormone-dependent manner. Expression of bcl-2 may occur more frequently in estrogen-related, low-grade endometrial carcinomas, whereas p53 overexpression is found more often in endometrial carcinomas in estrogen-unrelated, high-grade endometrial carcinomas with prominent proliferative activity and a high frequency of lymph node metastases.

Lymph node metastases in cervical and endometrial cancer are major prognostic factors. Lymph-nodal involvement determines adjuvant therapy. As imagery is not reliable to diagnose lymph node status, pelvic +/- para-aortic lymphadenectomy remains the gold standard. These surgical procedures are, however, responsible for specific morbidity: lymphocele and lymphedema. Sentinel lymph node procedure could avoid lymphadenectomy and their complications in cervical and endometrial cancer with good negative predictive values. We present actual indications, procedure and results of sentinel lymph node procedures in cervical and endometrial cancer.

The objective of this study was to identify pathological indicators that could be used to identify a subgroup of patients with apparent stage I endometrial cancer who do require retroperitoneal lymphadenectomy. 188 T1 endometrial cancer patients underwent primary surgery at Tokushima University Hospital. We retrospectively evaluated their clinical records and histopathological factors. Systematic lymphadenectomy was performed for 149 patients, and 39 patients (grade 1 with < 5 mm of myometrial invasion) were treated without lymphadenectomy. Lymph node metastases were found in 19 (12.8%) of the lymphadenectomy cases. Twenty-four patients with a T1a endometrium-limited lesion did not exhibit lymph node metastasis. Three (3.1%) of the 95 patients with a T1a lesion exhibited lymph node metastasis, and these 3 cases exhibited approximately 50% myometrial invasion. The 39 low-risk patients who did not undergo systematic lymphadenectomy remain alive without recurrence. Systematic lymphadenectomy could be omitted for patients with a grade 1 tumor and minor myometrial invasion of less than 5mm. J. Med. Invest. 65:221-224, August, 2018.

BACKGROUND To evaluate the diagnostic performance of MRI and 3D-TVS for assessment of deep myometrial invasion (MI), cervical involvement (CI), and Lymph node metastases (LNM) in endometrial cancer staging before surgery. MATERIAL AND METHODS From January 2016 to December 2017, we reviewed data from 314 women with endometrial cancer who underwent preoperative MRI and 3D-TVS before surgery. The diagnostic sensitivity, specificity, PPV, NPV, and accuracy in detecting MI, CI, and LNM were estimated based on ultimate pathology results. RESULTS The sensitivity, specificity, PPV, NPV, and accuracy of MRI in the diagnosis of MI were 89.19%, 88.97%, 67.35%, 97.99%, and 89.01%, respectively, and the indexes of 3D-TVS for MI were 86.36%, 91.07%, 79.17%, 94.44%, and 89.74%, respectively. The sensitivity, specificity, PPV, NPV, and accuracy of MRI for CI were 75% and 92.35%, 40.9%, 98.13%, and 91.2%, respectively. The indicators of 3D-TVS were 77.78%, 94.29%, 63.63%, 97.06%, and 92.4%, respectively. There were no significant differences in sensitivity, specificity, NPV, and accuracy between MRI and 3D-TVS in the diagnosis of MI and CI. For MI and CI, the sensitivity of combined MRI and 3D-TVS was higher than any other single method (P<0.05). For LNM, the sensitivity, specificity, PPV, NPV, and accuracy of MRI were 58.33%, 96.26%, 63.63%, 95.37%, and 92.43%, respectively. CONCLUSIONS 3D-TVS is equivalent to MRI in predicting MI and CI. Combined MRI and 3D-TVS can improve the assessment sensitivity, and they are useful in optimizing individualized surgical procedures. The sensitivity of MRI for LNM prediction needs to be improved.
