Characteristics of patients with late recurrence endometrial cancer.

AIM: We planned this study to assess endometrial cancer (EC) patients who had late metastasis. MATERIALS AND METHODS: This retrospective study constituted a review of the records of patients who were diagnosed with EC and underwent hysterectomy at the Gynecologic Oncology Clinic between 1996 and 2018. Relapses occurring after the first three years following primary treatment of EC are considered late recurrences. Post-relapse survival (PRS) refers to the time to the last follow-up or the patient's death after relapse. RESULTS: Late metastases were identified in 42 patients, 20 (47.6%) of whom had locoregional recurrence and 22 of whom (52.4%) had extrapelvic recurrence. Median disease-free survival (DFS) times were 61 (range: 43-78) and 65 (range: 48-81) months for the groups with locoregional and extrapelvic recurrences, respectively (P = 0.462). The 5-year PRS rate for the patients was 61.1%, with 63.8% having locoregional and 59.4% having extrapelvic late metastasis (P = 0.969). CONCLUSION: Among the patients with late metastases, those with endometrioid type EC were found to have a better prognosis. It has been shown that locoregional or extrapelvic organ recurrence does not significantly affect survival in patients with late relapse. Although our results are not statistically significant for cases of locoregional late metastases, surgical resection increases survival rates.

Third-trimester fetal pancreas imaging in uncomplicated pregnancies and association with pregnancy outcomes.

OBJECTIVE: To examine third-trimester sonographic imaging of the fetal pancreas in uncomplicated pregnancies and its association with pregnancy outcomes. METHODS: This was a prospective cohort study including 274 pregnant women. Uncomplicated pregnancies in the third trimester (28-40 weeks) were included in the study. Maternal chronic disease, pregnancy-related disorders such as hypertension, diabetes, cholestasis, smoking, and fetal abnormalities were determined as exclusion criteria. Sonographic fetal pancreatic measurement and echogenicity were evaluated in all participants. For intra-observer reliability, each participant's fetal pancreatic circumference was measured two times. The echogenicity of the pancreas was compared with the liver and ribs and classified as grade 1, 2, and 3. The pregnancy outcomes of all participants were obtained from the hospital digital registration system. RESULTS: The average fetal pancreatic circumference in the third trimester was 70.7 ± 0.6 mm (median, 70 [44-100.7]), with high intra-observer agreement (ICC 0.996 [0.995; 0.997]). A significant positive correlation was found between pancreatic circumference, body mass index (BMI), gestational age, and birth weight. Pancreatic measurements were significantly higher in composite adverse outcomes cases that included at least one of respiratory distress syndrome, hyperbilirubinemia, neonatal pneumonia, infection, and sepsis (p < 0.001). No relationship was found between pancreatic echogenicity and perinatal outcomes. CONCLUSION: Fetal pancreas size was positively correlated with gestational age, BMI, and birth weight, and increased fetal pancreas size was associated with composite adverse neonatal outcomes.

Risk factors for omental metastasis and the effect of omentectomy on survival in type 2 endometrial cancer patients.

To investigate the risk factors for occult omental metastasis and the effect of omentectomy on the survival of type 2 endometrial cancer (EC) patients. This study enrolled patients who were diagnosed with high-risk (grade 3, serous, clear cell, undifferentiated, carcinosarcoma, or mixed type) EC between 2000 and 2021 and underwent surgery in our center. Data from 482 patients were analyzed retrospectively. Omentectomy was performed in 405 (84.0%) patients. Omental metastases were detected in 61 (12.7%) patients. Eighteen (29.5%) of these metastases were occult. Adnexal involvement, malignant cytology, and peritoneal spread were independent risk factors for omental metastasis. The 5-year overall survival (OS) rate was 59.5% in patients who underwent omentectomy and 64.7% in those who did not (P = 0.558). In patients with and without omental metastases, the overall 5-year OS rates were 34.9% and 63.5%, respectively (P < 0.001). The 5-year OS rates of patients with a normal omentum, gross tumors, and occult metastases were 63.5%, 26.9%, and 52.5%, respectively (P < 0.001). Omental metastases is not uncommon in type II endometrial cancer; approximately one third of patients have occult metastases. Factors - positive cytology, adnexal involvement, and peritoneal involvement are associated with higher probability of omental metastases.

The clinical significance of lymphovascular space invasion in patients with low-risk endometrial cancer.

OBJECTIVE: The aim of this study was to assess the effect of lymphovascular space invasion on recurrence and disease-free survival in patients with low-risk endometrial cancer. METHODS: The study included patients with stage 1A, grade 1-2 endometrioid endometrial cancer who underwent a total hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy. Independent prognostic predictors of endometrial cancer recurrence were assessed using the Cox regression model. Binary logistic regression analysis was used to identify the predictors of distant recurrence. Kaplan-Meier analysis was used to describe survival curves, and the log-rank test was used to compare the differences in survival curves. RESULTS: A total of 189 patients met the inclusion criteria, of whom 24 (12.7%) had lymphovascular space invasion. The median follow-up time was 60 (3-137) months. Distant recurrence was present in 11 of 22 patients who developed recurrence. Kaplan-Meier survival analysis showed that the 5-year disease-free survival rates of patients with lymphovascular space invasion(+) and lymphovascular space invasion(-) were 62.5 and 91.9%, respectively, which were significantly lower (p<0.001). In multivariate Cox regression analysis, the presence of lymphovascular space invasion (p<0.001) and age ≥60 years (p=0.017) remained as prognostic factors for reduced disease-free survival. In binary logistic regression analysis, only lymphovascular space invasion (adjusted OR=13, 95%CI=1.456-116.092, p=0.022) was a prognostic factor for distant recurrence. CONCLUSION: lymphovascular space invasion is a prognostic risk factor for recurrence and distant metastasis and also a predictor of poorer disease-free survival outcomes in low-risk endometrial cancer.

The prognostic value of P53 index in predicting the recurrence of early low-risk endometrial cancer.

AIM: We aimed to clarify the clinical value of P53 index in patients with early low-risk endometrial cancer (EC) and find an optimal cut-off value of P53 index for predicting the recurrence of these patients. METHODS: The clinicopathological data of 157 patients with early low-risk EC (stage 1A with grade 1 or 2 endometrioid EC) were analyzed. The optimal cut-off value of the P53 index was calculated by the receiver operating characteristic curve analysis and Youden index. Cox regression model was used to evaluate the independent prognostic predictors of recurrence of EC. Then all patients were divided into two groups according to the optimal cut-off value of the P53 index. Differences of the clinicopathological parameters between the two groups were compared. RESULTS: Multivariate analysis showed age PR (p = 0.020) and P53 (p = 0.001) were independent prognostic factors for the recurrence of EC. The value of P53 index was found to be the optimal cut-off point of 17.5% in estimating the recurrence of EC. The 5-year recurrence-free survival rates of patients in the low P53 index group (<17.5%) and the high P53 index group (≥17.5%) were 94.6% and 65.4% (p < 0.001). CONCLUSION: It has been revealed that the P53 index is a prognostic factor for recurrence in early low-risk EC. The optimal cut-off value of P53 index may contribute to the postoperative individualized treatment options for early low-risk EC patients.
