Öğe Evaluation of outcome and prognostic factors in 739 patients with uterine cervix carcinoma: a single institution experience(Termedia Publishing House Ltd, 2015) Teke, Fatma; Yoney, Adnan; Teke, Memik; Adanas, Gultekin; Urakci, Zuhat; Tukcu, Gu; Eren, BekirAim of the study: The aim of this retrospective chart review was to determine the long-term outcomes and identify prognostic factors that impact the survival of patients with cervical cancer. Material and methods: A retrospective chart review of 739 patients with International Federation of Gynaecology and Obstetrics (FIGO) stage I-IV cervical cancer treated with surgery, radiation or chemoradiation was performed. Patient charts were evaluated in terms of demographics, clinical outcomes, and survival. Disease-free survival (DFS) and overall survival (OS) were calculated with the Kaplan-Meier method, and differences in survival were compared with the log-rank test. Multivariate analysis was performed with a Cox proportional hazards model to determine the estimated hazard ratios (HR) with 95% confidence intervals (CI) for each prognostic factor. Results: The Cox proportional hazards model demonstrated that pelvic nodal metastasis (p = 0.018), parametrial invasion (p = 0.015), and presence of disease in the surgical margin (p = = 0.011) were all independent prognostic factors for OS. The 5-year OS rate of patients with negative pelvic lymph nodes was 67.1%, which was higher than the rate for those with positive nodes at 49.0% (p < 0.05). The 5-year OS rate was 54.3% for patients with metastasis to the parametrium, 79.2% with a cancer-free parametrium, 60.9% with a cancer-positive surgical margin, 85.4% with a cancer-negative surgical margin, and 64.3% with a 1-3 mm close surgical margin (p < 0.05). Conclusions: Assessing pelvic lymph nodes, the parametrium, and surgical margins is important for survival and may aid in better identifying patients who would derive greater benefits from receiving adjuvant therapies and more aggressive treatments.Öğe The impact of the stage and tumor size on brain metastasis of cervical cancer.(Amer Soc Clinical Oncology, 2015) Teke, Fatma; Tunc, Senem Yaman; Teke, Memik; Turan, Yahya; Urakci, Zuhat; Altin, Suleyman; Eren, Bekir[Abstract Not Available]Öğe The impact of the stage and tumor size on rare brain metastasis of cervical cancer(Turkish Neurosurgical Soc, 2016) Teke, Fatma; Tunç, Senem Yaman; Teke, Memik; Turan, Yahya; Urakçı, Zuhat; Eren, Bekir; Altın, SüleymanAIM: To investigate the clinical features, prognostic factors and survival times of cervical cancer patients with brain metastasis. MATERIAL and METHODS: We retrospectively reviewed the medical records of 820 patients with cervical cancer. Data were analyzed using SPSS version 12.0 statistical software (SPSS, Chicago, IL, USA). Overall survival, time interval from diagnosis of cervical cancer to identification of brain metastasis, and median survival time after diagnosis of brain metastasis were calculated using Kaplan-Meier curve analysis. The log-rank test was used to compare differences in survival. Differences were assumed statistically significant when p-values were <0.05. RESULTS: The incidence of brain metastases from cervical cancer in our institution was 1.82% (15/820) over a ten-year period. The median time interval from diagnosis of cervical cancer to detection of brain metastasis was 12.5 months (range: 2.9-91.9 months). Stage and tumor diameter were found to be significant relating to the interval from diagnosis of cervical cancer to detection of brain metastasis (p=0.001 for both). CONCLUSION: This study provides much information about the prognosis of patients with brain metastases from cervical cancer and highlights the importance of initial stage and tumor diameter when determining the time interval until development of brain metastasis.Öğe Lack of any Impact of Histopathology Type on Prognosis in Patients with Early-Stage Adenocarcinoma and Squamous Cell Carcinoma of the Uterine Cervix(Asian Pacific Organization Cancer Prevention, 2014) Teke, Fatma; Yoney, Adnan; Teke, Memik; Inal, Ali; Urakci, Zuhat; Eren, Bekir; Zincircioglu, Seyit BurhanedtinBackground: The aim of this study was to evaluate the prognosis of patients with stage IA-IIB cervical carcinoma and to investigate a possible correlation of histology with prognosis. Materials and Methods: Two hundred fifty one patients with adenocarcinoma and squamous cell carcinoma (SCC) histology for FIGO (International Federation of Gynecology and Obstetrics) stage IA-IIB uterine cervical carcinomas at the Radiation Oncology Clinic of GH Okmeydani Training and Research Hospital between January 1996 and December 2006 were selected, analyzed retrospectively and evaluated in terms of general characteristics and survival. Disease-free survival (DFS) and overall survival (OS) was calculated using the Kaplan-Meier method and differences were compared with the log-rank test. Multivariate analysis using a Cox-proportional hazards model was used to adjust for prognostic factors and to estimate hazard ratio (HR) with 95% confidence interval (CI). Results: There was no differences between the two tumour types in age, stage, pelvic nodal metastasis, parametrial invasion, surgical margin status, DSI, LVSI, maximal tumor diameter, grade, and treatment modalities. 5-year OS and DFS were 73% and 77%, versus 64% and 69%, for SCC and adenocarcinoma, respectively (p>0.05). Multivariate analysis revealed independent prognostic factors including pelvic nodal metastasis and resection margin status for OS (p=0.008, p=0.002, respectively). Conclusions: Prognosis of FIGO stage IA-IIB cervical cancer patients was found to be the same for those with adenocarcinoma and SCC.
