(2017) Haberal, Ali; Kocaman, Eda; Dursun, Polat; Ayhan, Ali; Korkmaz, Vakkas; Meydanli, Mehmet Mutlu; Yalcin, Ibrahim; Sari, Mustafa Erkan; Sahin, Hanifi; Gungor, Tayfun; 0000-0002-1741-7035; 0000-0002-1486-7209; 0000-0002-7869-9662; 29027396; AAI-9331-2021; AAJ-5802-2021
Objective: To compare the clinical validity of the Gynecologic Oncology Group-99 (GOG-99), the Mayo-modified and the European Society for Medical Oncology (ESMO)-modified criteria for predicting lymph node (LN) involvement in women with endometrioid endometrial cancer (EC) clinically confined to the uterus. Methods: A total of 625 consecutive women who underwent comprehensive surgical staging for endometrioid EC clinically confined to the uterus were divided into low- and high-risk groups according to the GOG-99, the Mayo-modified, and the ESMO-modified criteria. Lymphovascular space invasion is the cornerstone of risk stratification according to the ESMO-modified criteria. These 3 risk stratification models were compared in terms of predicting LN positivity. Results: Systematic LN dissection was achieved in all patients included in the study. LN involvement was detected in 70 (11.2%) patients. LN involvement was correctly estimated in 51 of 70 LN-positive patients according to the GOG-99 criteria (positive likelihood ratio [LR+], 3.3; negative likelihood ratio [LR-], 0.4), 64 of 70 LN-positive patients according to the ESMO-modified criteria (LR+, 2.5; LR-, 0.13) and 69 of the 70 LN-positive patients according to the Mayo-modified criteria (LR+, 2.2; LR-, 0.03). The area under curve of the Mayo-modified, the GOG-99 and the ESMO-modified criteria was 0.763, 0.753, and 0.780, respectively. Conclusion: The ESMO-modified classification seems to be the risk-stratification model that most accurately predicts LN involvement in endometrioid EC clinically confined to the uterus. However, the Mayo-modified classification may be an alternative model to achieve a precise balance between the desire to prevent over-treatment and the ability to diagnose LN involvement.
Endometrioid tip endometrium kanserinde paraaortik lenf nodu tutulumu için risk faktörleri
(Başkent Üniversitesi Tıp Fakültesi, 2018) Kocaman, Eda; Kuşçu, Ülkü Esra
Bu çalışmanın amacı, tamamına komplet cerrahi evreleme uygulanmış endometrioid tip endometrium kanseri (EEK) hastalarında, paraaortik lenf nodu (LN) metastazı için risk faktörlerini belirlemekti. Bu çalışmada, 2007-2018 yılları arasında Başkent Üniversitesi Ankara Hastanesi’nde endometrium kanseri nedeniyle opere edilen hastaların verileri retrospektif olarak incelendi. Pelvik ve paraaortik lenfadenektomiyi de içeren cerrahi uygulanmış olan olan 894 EEK hastası çalışmaya dahil edildi. Hasta verileri paraaortik lenf nodu tutumu açısından değerlendirildi ve paraaortik lenf nodu metastazı (PALNM) için prediktif faktörleri saptamak amacıyla tek değişkenli ve çok değişkenli lojistik regresyon modelleri kullanıldı. Hastaların 87 (%9,7)’sinde lenf nodu metastazı mevcuttu ve izole pelvik, izole paraaortik ve pelvik-paraaortik lenf nodu metastazı; sırasıyla, 48 (%5,4), 6 (%0,7) ve 33 (%3,7) hastada saptandı. Tek değişkenli analizde; derin myometrial invazyon, grade 3 tümör, primer tümör çapı (≥2 cm), servikal stromal invazyon, yükselmiş Ca-125 değeri, lenfovasküler alan invazyonu (LVSİ), serozal tutulum, adneksiyal tutulum, pelvik lenf nodu metastazı varlığı ve metastatik pelvik LN sayısının iki veya ikiden daha fazla olmasının, PALNM riskini istatistiksel olarak anlamlı şekilde arttırdığı saptanırken (p < 0,001); tanı yaşı (p=0,83) ve metastatik pelvik lenf nodu boyutu çapının (p=0,50) , bu açıdan istatistiksel olarak anlamlı bir etkisi saptanmadı. Çok değişkenli analizde ise, EEK hastalarında, pelvik LN metastazı varlığı [odds oranı (OR), 13,1; %95 güven aralığı (GA), 3,27-52,9; p < 0,001] ve pozitif pelvik LN sayısının iki veya ikiden daha fazla olması [OR, 4,4; %95 GA, 1,25-15,8; p =0,021], PALNM için bağımsız risk faktörleri olarak saptandı. EEK’de pelvik lenf nodu tutulumunun yanı sıra metastatik pelvik lenf nodu sayısının iki veya ikiden daha fazla olması, PALNM için bağımsız risk faktörleri olarak görünmektedir. The aim of this study was to determine the risk factors for paraaortic lymph node (LN) metastasis in endometiroid type endometrial cancer (EEC) patients who underwent comprehensive surgical staging. The data of patients who underwent surgery for endometrial cancer at Baskent University Ankara Hospital between 2007 and 2018 were reviewed retrospectively. A total of 894 patients with EEC who underwent surgery including pelvic and paraaortic lymphadenectomy included in this study. Patient data were analyzed with respect to paraaortic lymph node metastasis (PALNM), and univariate and multivariate logistic regression models were used to identify the predictive factors for PALNM. Lymph node metastasis was detected in 87 (%9.7) patients, isolated pelvic LN metastasis in 48 (%5.4), isolated PALNM in 6 (%0.7), and both pelvic and paraaortic metastasis in 33 (%3.7) patients, respectively. The risk of PALNM was shown to significantly increase in patients with deep myometrial invasion, grade 3 tumor, primary tumor diameter (≥2 cm), cervical stromal invasion, elevated serum Ca-125 level, lymphovascular space invasion (LVSI), serosal invasion, adnexal involvement, pelvic LN metastasis and two or more positive pelvic LNs (p < 0.001) whereas age at diagnosis (p=0.83) and the diameter of the metastatic pelvic LN (p=0.50) did not seem to have a significant effect, at the end of univariate analysis. Multivariate analysis showed that the presence of pelvic LN metastasis [odds ratio (OR), 13,1; 95% confidence interval (CI), 3.27-52.9; p < 0.001] and two or more positive pelvic LNs [OR, 4,4; 95% CI, 1.25-15.8; p =0.021] as independent risk factors for PALNM in women with EEC. The presence of two or more metastatic pelvic LNs besides pelvic LN involvement appear to be independent risk factors for PALNM in patients with EEC.
Maternal and cord blood homocysteine, vitamin B12, folate, and B-type natriuretic peptide levels at term for predicting congenital heart disease of the neonate: A case-control study
(2019) Sahin-Uysal, Nihal; GUlumser, Cagri; Kocaman, Eda; Varan, Birgul; Bayraktar, Nilufer; Yanik, Filiz; 0000-0001-5385-5502; 0000-0002-7886-3688; 0000-0002-1741-7035; 0000-0002-4066-9038; 31256695; AAA-9475-2020; Y-8758-2018; C-6543-2018
Objective: To investigate the effectiveness of the metabolic markers homocysteine, vitamin B12, folate, and B-type natriuretic peptide in maternal and cord blood for detecting congenital heart disease. Methods: Homocysteine, vitamin B12, folate, and B-type natriuretic peptide concentrations in maternal and cord blood samples at term were measured in the case (n = 42) and control (n = 43) groups with and without fetal congenital heart disease, respectively. Additionally, newborns with congenital heart disease were divided into two subgroups: those with (n = 30) and without (n = 8) 6-month infant survival. The case and control groups and case subgroups were compared with each other with respect to maternal age, gravidity, parity, gestational age at delivery, birth weight, maternal and cord blood levels of homocysteine, vitamin B12, folate, and B-type natriuretic peptide, and arterial cord blood pH and base excess values. Statistical analyses were performed using SPSS for Windows, version 22.0. The Student's t-test, the Mann-Whitney U test, and the chi(2) test were used where appropriate. A p value of < .05 was considered statistically significant. Results: Mean maternal age, birth weight and median gravidity, parity and gestational age at delivery were not significantly different between the case and control groups, as well as between the case subgroups (all p > .05). Concentrations of metabolic markers in maternal blood were not significantly different between the two groups (p > .05). Homocysteine and B-type natriuretic peptide levels in cord blood samples were significantly higher, whereas folate levels were significantly lower in the case group compared with the control group (all p < .05). Cord blood B-type natriuretic peptide levels were significantly higher (p < .05) and arterial cord blood pH values were significantly lower (p < .05) in the case subgroup without 6-month infant survival compared with the case subgroup with 6-month infant survival. Conclusion: High cord blood B-type natriuretic peptide and homocysteine levels and low cord blood folate levels at term may be useful for predicting congenital heart disease in the neonate. Neonates with congenital heart disease who have high cord blood B-type natriuretic peptide and low pH values may have adverse outcomes.
Oncological and obstetric outcomes after fertility-sparing radical abdominal trachelectomy for early stage cervical cancer: a tertiary centre's 10 years' experience
(2019) Ayhan, Ali; Tohma, Yusuf Aytac; Sahin, Hanifi; Kocaman, Eda; Tunc, Mehmet; Haberal, Asuman Nihan; 0000-0001-9418-4733; 30371139; AAE-6482-2021
The aim of this study is to present our clinical experience about fertility-sparing procedures in early stage cervical cancer and its obstetrical and oncological outcomes. Between the years 2006 and 2016, a total of 22 early stage cervical cancer patients who underwent a fertility-sparing radical abdominal trachelectomy in our clinic were retrospectively analysed. The median age was 33 (range: 28-39) years. The median follow-up was 47 (range: 22-125) months. Five patients (22.7%) had Stage IA1, three patients had (13.6%) Stage IA2, and 14 patients (63.6%) had Stage IB1 disease. Only one patient had a recurrence. A pregnancy was obtained in five patients (22.7%) and one of them (20%) had a live birth. A pregnancy was obtained spontaneously in two patients (40%), whereas assisted reproductive techniques were used in three of the patients (60%). A miscarriage occurred in two patients (40%), and one of them was within the first trimester and the other was within the second trimester.
Prognostic factors and treatment outcomes in surgically-staged non-invasive uterine clear cell carcinoma: a Turkish Gynecologic Oncology Group study
(2017) Sari, Mustafa Erkan; Meydanli, Mehmet Mutlu; Turkmen, Osman; Comert, Gunsu Kimyon; Turan, Ahmet Taner; Karalok, Alper; Sahin, Hanifi; Kocaman, Eda; Akbayir, Ozgur; 0000-0002-1741-7035; 28541637
Objective: To assess the prognosis of surgically-staged non-invasive uterine clear cell carcinoma (UCCC), and to determine the role of adjuvant therapy. Methods: A multicenter, retrospective department database review was performed to identify patients with UCCC who underwent surgical treatment between 1997 and 2016 at 8 Gynecologic Oncology Centers. Demographic, clinicopathological, and survival data were collected. Results: A total of 232 women with UCCC were identified. Of these, 53 (22.8%) had surgically-staged non-invasive UCCC. Twelve patients (22.6%) were upstaged at surgical assessment, including a 5.6% rate of lymphatic dissemination (3/53). Of those, 1 had stage IIIA, 1 had stage IIIC1, 1 had stage IIIC2, and 9 had stage IVB disease. Of the 9 women with stage IVB disease, 5 had isolated omental involvement indicating omentum as the most common metastatic site. UCCC limited only to the endometrium with no extra-uterine disease was confirmed in 41 women (73.3%) after surgical staging. Of those, 13 women (32%) were observed without adjuvant treatment whereas 28 patients (68%) underwent adjuvant therapy. The 5-year disease-free survival rates for patients with and without adjuvant treatment were 100.0% vs. 74.1%, respectively (p=0.060). Conclusion: Extra-uterine disease may occur in the absence of myometrial invasion (MMI), therefore comprehensive surgical staging including omentectomy should be the standard of care for women with UCCC regardless of the depth of MMI. Larger cohorts are needed in order to clarify the necessity of adjuvant treatment for women with UCCC truly confined to the endometrium.
Recurrence patterns and prognostic factors in lymphovascular space invasion-positive endometrioid endometrial cancer surgically confined to the uterus
(2019) Sahin, Hanifi; Meydanli, Mehmet Mutlu; Sari, Mustafa Erkan; Kocaman, Eda; Cuylan, Zeliha Fırat; Yalcin, Ibrahim; Coban, Gonca; Ozen, Ozlem; Sirvan, Levent; Gungor, Tayfun; Ayhan, Ali; 30638487
Objective: The purpose of this study was to determine the patterns of failure and prognostic factors for lymphovascular space invasion (LVSI)-positive endometrioid endometrial cancer (EC) patients in the setting of negative lymph nodes (LNs). Materials and methods: A multicenter, retrospective department database review was performed to identify LVSI-positive patients with disease surgically confined to the uterus at two gynecologic oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. Results: We identified 185 LVSI-positive women with negative LNs during the study period. Fifty-five (29.7%) were classified as Stage IA, 94 (50.8%) as Stage IB, and 36 (19.5%) as Stage II. The median age at diagnosis was 59 years and the median duration of follow-up was 44 months. The total number of the recurrences was 12 (6.5%). We observed 5 (2.9%) loco-regional recurrences, 3 (1.5%) retroperitoneal failures, and 4 (2.0%) distant relapses. The 5-year progression-free survival (PFS) was 86.1% while the 5-year overall survival (OS) rate was 87.7%. Grade 3 histology (Hazard Ratio [HR] 2.9, 95% Confidence Interval [CI] 1.02-8.50; p = 0.04), cervical stromal invasion (HR 4.5, 95% CI 1.61-12.79; p = 0.004) and age > 60 years (HR 5.8, 95% CI 1.62-21.32; p = 0.007) were found to be independent prognostic factors for decreased OS. Adjuvant treatment did not appear as a prognostic factor for OS even in univariate analysis. Conclusion: The recurrence rate among LVSI-positive endometrioid EC patients is low in the setting of negative LNs. However, one out of three patients with a recurrence experiences distant relapses which usually portend worse outcomes. (C) 2018 Taiwan Association of Obstetrics & Gynecology.
