RESUMO
OBJECTIVE: To compare survival measures of women with Stage I high-grade endometrial cancer who underwent either hysteroscopy or a non-hysteroscopic procedure as a diagnostic procedure. STUDY DESIGN: 298 patients with stage I high grade endometrial cancer who underwent surgery between 2002 and 2014. Patients were divided into two groups: hysteroscopy and non-hysteroscopy (curettage or office endometrial biopsy). Clinical, pathological, and survival measures were compared between the groups. High grade histology included endometroid grade -3, uterine serous papillary carcinoma, clear cell carcinoma, and carcinosarcoma. RESULTS: There were 71 patients in the hysteroscopy group and 227 patients in the non-hysteroscopy group. The median follow-up was 52 months (range 12-120 months). There were no differences between the groups in the 5-year recurrence-free survival (73.9 % vs. 79.7 %; p = 0.65), disease-specific survival (79.3 % vs. 83.6 %; p = 0.87), and overall survival (65.7 % vs. 80.3 %; p = 0.35). CONCLUSION: Hysteroscopic diagnosis in women with early-stage and high-grade endometrial cancer does not adversely affect the survival outcomes.

OBJECTIVE: The aim of the present study was to asses the ability of Her-2/neu immunohistochemical staining of the molar tissue to predict the risk of developing gestational trophoblastic neoplasia (GTN). METHODS: Sections prepared from 33 consecutive formalin-fixed paraffin-embedded archival reconfirmed hydatidiform mole tissue blocks were immunohistochemically stained for Her-2/neu. The staining was scored according to the subjectively evaluated intensity of staining and the proportion of stained villous cytotrophoblastic cells. Clinical data were abstracted from medical files. RESULTS: 23 patients had a complete and 10 a partial mole. Nine patients (27.3%) were diagnosed with GTN [7 of 23 patients with a complete mole (30.4%) and 2 of the 10 (20.0%) with a partial mole]. A positive immunohistochemical Her-2/neu stain was found in 6 (18.2%) of the patients with hydatidiform mole (3 with a complete mole). The rate of Her-2/neu expression was somewhat higher in moles with subsequent GTN than in moles with an uneventful course (22.2% vs. 16.6%, respectively). The difference did not reach significance (Fisher's Exact Test, P=0.55) possibly due to the small number of cases (power of <5%). The sensitivity and specificity of Her-2/neu expression for prediction of GTN was 22.2% and 83.3%, respectively, and the positive and negative predictive value 33.3% and 74.1%, respectively. CONCLUSION: While the specificity of Her-2/neu immunohistochemical staining for prediction of GTN is relatively high, the low sensitivity and low positive and negative predictive value precludes its practical clinical use for prediction of post-molar GTN. The quest for a precise predictor of post-molar GTN should continue.
