Öğe Clinical and Pathologic Features of Patients with Rare Ovarian Tumors: Multi-Center Review of 167 Patients by the Anatolian Society of Medical Oncology(Asian Pacific Organization Cancer Prevention, 2013) Bilici, Ahmet; Inanc, Mevlude; Ulas, Arife; Akman, Tulay; Seker, Mesut; Babacan, Nalan Akgul; Inal, AliBackground: Non-epithelial malignant ovarian tumors and clear cell carcinomas, Brenner tumors, transitional cell tumors, and carcinoid tumors of the ovary are rare ovarian tumors (ROTs). In this study, our aim was to determine the clinicopathological features of ROT patients and prognostic factors associated with survival. Materials and Methods: A total of 167 patients with ROT who underwent initial surgery were retrospectively analyzed. Prognostic factors that may influence the survival of patients were evaluated by univariate and multivariate analyses. Results: Of 167 patients, 75 (44.9%) were diagnosed with germ-cell tumors (GCT) and 68 (40.7%) with sex cord-stromal tumors (SCST); the remaining 24 had other rare ovarian histologies. Significant differences were found between ROT groups with respect to age at diagnosis, tumor localization, initial surgery type, tumor size, tumor grade, and FIGO stage. Three-year progression-free survival (PFS) rates and median PFS intervals for patients with other ROT were worse than those of patients with GCT and SCST (41.8% vs 79.6% vs 77.1% and 30.2 vs 72 vs 150 months, respectively; p=0.01). Moreover, the 3-year overall survival (OS) rates and median OS times for patients with both GCT and SCST were better as compared to patients with other ROT, but these differences were not statistically significant (87.7% vs 88.8% vs 73.9% and 170 vs 122 vs 91 months, respectively; p=0.20). In the univariate analysis, tumor localization (p<0.001), FIGO stage (p<0.001), and tumor grade (p=0.04) were significant prognostic factors for PFS. For OS, the univariate analysis indicated that tumor localization (p=0.01), FIGO stage (p=0.001), and recurrence (p<0.001) were important prognostic indicators. Multivariate analysis showed that FIGO stage for PFS (p=0.001, HR: 0.11) and the presence of recurrence (p=0.02, HR: 0.54) for OS were independent prognostic factors. Conclusions: ROTs should be evaluated separately from epithelial ovarian cancers because of their different biological features and natural history. Due to the rarity of these tumors, determination of relevant prognostic factors as a group may help as a guide for more appropriate adjuvant or recurrent therapies for ROTs.Öğe The impact of systemic inflammatory markers on survival in metastatic gastric cancer patients receiving first-line chemotherapy(2019) Bozkurt, Oktay; Firat, Sedat Tarik; Dogan, Ender; Cosar, Ramazan; Inanc, Mevlude; Ozkan, MetinABSTRACT Aim: The prognostic impact of elevated systemic inflammatory tools, including the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR), remains moot in cancer patients. This research was performed to explore the predictive worth of these markers for prognoses in metastatic gastric cancer (mGC) patients receiving chemotherapy.Material and Methods: We retrospectively appraised 158 patients diagnosed with mGC between February 2009 and November 2017. According to threshold values that were identified by receiver operating characteristic (ROC) curve analysis, the NLR and PLR were each divided into two groups: ≤ 2.11 and >2.11, ≤ 158.8, and >158.8, respectively. The Cox proportional hazards model was applied to uncover the probable predictors of progression-free survival (PFS) and overall survival (OS).Results: According to univariate analysis, poor performance status, high NLR, high PLR, and anemia were significantly correlated with inferior OS receiving first-line palliative chemotherapy. High NLR, high PLR, and anemia were significantly correlated with poor PFS. In the multiple analysis, an elevated NLR was identified to be an independent predictor of inferior OS (OR: 2.70, 95% CI: 1.75-4.16, p0.001) and PFS (OR: 1.47, 95% CI: 1.00-2.17, p=0.047). Additionally, anemia was independent prognostic factors for the OS (OR: 0.69, 95% CI: 0.47-0.99, p=0.046).Conclusion: Findings of this research revealed that NLR was an independent prognostic tool of PFS and OS in mGC patients undergoing first-line chemotherapy.Keywords: Metastatic gastric cancer; neutrophil to lymphocyte ratio; platelet-to-lymphocyte ratio; prognosis.Öğe Is lymph node ratio prognostic factor for survival in elderly patients with node positive breast cancer? The Anatolian Society of Medical Oncology(Edizioni Luigi Pozzi, 2013) Inal, Ali; Akman, Tulay; Yaman, Sebnem; Ozturk, Selcuk Cemil; Geredeli, Caglayan; Bilici, Mehmet; Inanc, MevludeSeveral studies have now demonstrated that the lymph node ratio (LNR), as a superior indicator of axillary tumor burden to the number of excised nodes. While, about the prognostic value of LNR on the the survival of elderly patients is limited. The aim of this retrospective multicenter study is to evaluate the prognostic value of lymph node ratio in elderly patients with node positive breast cancer. METHODS: Onehundredeightyfour patient with operable breast cancer, recruited from 17 institutions, were enrolled into the retrospectively study. Eleven potential prognostic variables were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. RESULT: Among the eleven variables of univariate analysis, four variables were identified to have prognostic significance for Overall survival (OS): pathologic tumor size (T), No. of positive nodes (N), LNR and estrogen receptor-positive (ER). Among the eleven variables of univariate analysis, two variables were identified to have prognostic significance for Disease-free survival (DFS): N and LNR. Multivariate analysis by Cox proportional hazard model showed that 7; LNR and ER were considered independent prognostic factors for OS. Furthermore, LNR was considered independent prognostic factors for DFS. CONCLUSION: In conclusion, the LNR was associated with the prognostic importance for DFS and OS in elderly patients who were administered adjuvant treatments.Öğe IS SECOND LINE SYSTEMIC CHEMOTHERAPY BENEFICIAL IN PATIENTS WITH NON-SMALL CELL LUNG CANCER (NSCLC)? : A MULTICENTER DATA EVALUATION OF ANATOLIAN SOCIETY OF MEDICAL ONCOLOGY (ASMO)(Lippincott Williams & Wilkins, 2013) Odabas, Hatice; Ulas, Arife; Aydin, Kubra; Inanc, Mevlude; Aksoy, Asude; Yazilitas, Dogan; Turkeli, Mehmet[Abstract Not Available]Öğe Is second-line systemic chemotherapy beneficial in patients with non-small cell lung cancer (NSCLC)? A multicenter data evaluation by the Anatolian Society of Medical Oncology(Sage Publications Ltd, 2015) Odabas, Hatice; Ulas, Arife; Aydin, Kubra; Inanc, Mevlude; Aksoy, Asude; Yazilitas, Dogan; Turkeli, MehmetPatients with advanced non-small cell lung cancer (NSCLC) generally require second-line treatment although their prognosis is poor. In this multicenter study, we aimed to detect the characteristics related to patients and disease that can predict the response to second-line treatments in advanced NSCLC. Data of 904 patients who have progressed after receiving first-line platinum-based chemotherapy in 11 centers with the diagnosis of stage IIIB and IV NSCLC and who were evaluated for second-line treatment were retrospectively analyzed. The role of different factors in determining the benefit of second-line treatment was analyzed. Median age of patients was 57 years (range 19-86). Docetaxel was the most commonly used (20.9 %, n = 189) single agent, while gemcitabine-platinum was the most commonly used (6.7 %, n = 61) combination chemotherapy regimen in second-line setting. According to survival analysis, median progression-free survival after first-line treatment (PFS2) was 3.5 months (standard error (SE) 0.2; 95 % confidence interval (CI), 3.2-3.9), median overall survival (OS) was 6.7 months (SE 0.3; 95 % CI, 6.0-7.3). In multivariate analysis, independent factors affecting PFS2 were found to be hemoglobin (Hb) level over 12 g/dl and treatment-free interval (TFI) longer than 3 months (p = 0.006 and 0.003, respectively). Similarly, in OS analysis, Hb level over 12 g/dl and time elapsed after the first-line treatment that is longer than 3 months were found to be independent prognostic factors (p = 0.0001 and 0.045, respectively). In light of these findings, determining and using the parameters for which the treatment will be beneficial prior to second-line treatment can increase success rate.Öğe Pathologic and Clinical Characteristics of Elderly Patients With Breast Cancer: A Retrospective Analysis of a Multicenter Study (Anatolian Society of Medical Oncology)(Int College Of Surgeons, 2014) Inal, Ali; Akman, Tulay; Yaman, Sebnem; Ozturk, Selcuk Cemil; Geredeli, Caglayan; Bilici, Mehmet; Inanc, MevludeThere is very little information about breast cancer characteristics, treatment choices, and survival among elderly patients. The purpose of this multicenter retrospective study was to examine the clinical, pathologic, and biologic characteristics of 620 breast cancer patients age 70 years or older. Between June 1991 and May 2012, 620 patients with breast cancer, recruited from 16 institutions, were enrolled in the retrospective study. Patients had smaller tumors at diagnosis; only 15% of patients had tumors larger than 5 cm. The number of patients who had no axillary lymph node involvement was 203 (32.7%). Ninety-three patients (15.0%) had metastatic disease at diagnosis. Patients were characterized by a higher fraction of pure lobular carcinomas (75.3%). The tumors of the elderly patients were also more frequently estrogen receptor (ER) positive (75.2%) and progesterone receptor (PR) positive (67.3%). The local and systemic therapies for breast cancer differed according to age. An association between age and overall survival has not been demonstrated in elderly patients with breast cancer. In conclusion, the biologic behavior of older patients with breast cancer differs from younger patients, and older patients receive different treatments.Öğe Risk factors for 30-day mortality in patients with cancer and COVID-19 in Turkey: A single center retrospective study(2022) Mutlu, Emel; Firat, Sedat Tarik; Inanc, Mevlude; Bozkurt, Oktay; Cosar, Ramazan; Ozkan, MetinAim: We aimed to investigate the factors affecting mortality in cancer patients with COVID-19. Materials and Methods: 120 cancer patients followed-up in Erciyes University Medical Oncology Department were included in the study. Patients with a diagnosed cancer over the age of 18 years and diagnosis of COVID-19 between April 1 and December 1 2020 were participated in the study. The relationship between clinical, demographic, laboratory values and 30-day mortality were evaluated using the Chi-square and Fisher's exact test. Risk factors for mortality were identified by univariable and multivariable logistic regression models. Results: 120 cancer patients were accepted in the study and 30 (25%) had died within 30 days after COVID-19 positivity. Hospitalization rate of cancer patients with COVID-19 was 67.5% and 23 (19.2%) of patients were admitted to intensive care unit (ICU). 34.6% of hospitalized patients and 95.7% of those admitted in the ICU died within 30 days. In multivariable logistic regression analysis, it was concluded that the presence of lymphopenia (OR 2.2, 95% CI 1.54-13.6, p = 0.04), high neutrophil-lymphocyte ratio (NLR) (OR 3.1, 95% CI 1.21-9.8, p = 0.02), dyspnea (OR 2.5 95% CI 0.32-11.2, p = 0.04), lung cancer diagnoses (OR 3.3 95% CI 1.54-9.7, p = 0.03), male gender (OR 2.17 95% CI 1.1-7.3, p = 0.03) ) were determined that increased 30-day mortality. Conclusion: High incidence of cancer and the risk of immunosuppression in these patients increased the importance of COVID-19. Cancer patients with COVID-19 need to be treated more carefully because they are vulnerable to infection and can be mortal.Öğe Risk factors for brain metastasis as a first site of disease recurrence in patients with HER2 positive early stage breast cancer treated with adjuvant trastuzumab(Churchill Livingstone, 2016) Tonyali, Onder; Coskun, Ugur; Yuksel, Sinemis; Inanc, Mevlude; Bal, Oznur; Akman, Tulay; Yazilitas, DoganPurpose: The aim of this study was to determine risk factors for brain metastasis as the first site of disease recurrence in patients with HER2-positive early-stage breast cancer (EBC) who received adjuvant trastuzumab. Methods: Medical records of 588 female patients who received 52-week adjuvant trastuzumab from 14 centers were evaluated. Cumulative incidence functions for brain metastasis as the first site of disease recurrence and the effect of covariates on brain metastasis were evaluated in a competing risk analysis and competing risks regression, respectively. Results: Median follow-up time was 36 months. Cumulative incidence of brain metastasis at 12 months and 24 months was 0.6% and 2%, respectively. HER2-enriched subtype (ER- and PR-) tumor (p = 0.001, RR: 3.4, 95% CI: 1.33-8.71) and stage 3 disease (p = 0.0032, RR: 9.39, 95% CI: 1.33-8.71) were significant risk factors for development of brain metastasis as the first site of recurrence. Conclusions: In patients with HER2 positive EBC who received adjuvant trastuzumab, HER2-enriched subtype (ER- and PR-) tumor and stage 3 disease were associated with increased risk of brain metastasis as the first site of disease recurrence.
