Öğe Bevacizumab plus irinotecan in recurrent or progressive malign glioma: a multicenter study of the Anatolian Society of Medical Oncology (ASMO)(Springer, 2013) Demirci, Umut; Tufan, Gulnihal; Aktas, Bilge; Balakan, Ozan; Alacacioglu, Ahmet; Dane, Faysal; Engin, HuseyinThe overall prognosis for recurrent malignant glioma (MG) is extremely poor, and treatment options are limited. We evaluated our multicenter retrospective experience for patients with recurrent MG administering bevacizumab and irinotecan in combination therapy. A total of 115 patients with grade IV glial tumor (n = 93) and grade III glial tumor (n = 22) were retrospectively evaluated at 14 centers in Turkey. Primary objectives of the study were to evaluate the efficacy and toxicity of the bevacizumab and irinotecan as salvage treatment based on response to therapy, progression-free survival (PFS), 6 months of PFS, overall survival (OS), and 6 months of OS (OS6). Bevacizumab and irinotecan were performed as second line (79.1 %) and third line treatment (20.9 %). Median chemotherapy cycle was 6 (range 1-37), and median follow-up was 6 months (range 1-36 months). Objective response rate was 39.1 %. Six-month PFS and OS6 were 46.3 % and 67.5 %, respectively. Median PFS was 6 months (95 % CI 2.5-9.5) and 6 months (95 % CI 4.9-7.1) in the grade III and IV groups, respectively (p = 0.773). Median OS was 9 months (95 % CI 7.1-10.9) and 8 months (95 % CI 6.6-9.4) in the grade III and IV groups, respectively (p = 0.450). Serious toxicities were observed in 7.8 % of patients. Treatment-related toxic death was observed in 3 patients. There was no treatment related to central nervous system hemorrhage or other serious hemorrhages. Present study results were consistent with previous studies. In addition, we detected similar outcomes in grade III and IV glial tumors.Öğe Breast cancer subtypes and the risk of distant relapse after breast conserving surgery or mastectomy: An Anatolian Society of Medical Oncology study.(Amer Soc Clinical Oncology, 2015) Kaplan, Muhammet Ali; Urakci, Zuhat; Uncu, Dogan; Dane, Faysal; Ozkan, Metin; Akman, Tulay; Harputluoglu, Hakan[Abstract Not Available]Öğe Impact of adjuvant treatment modalities on survival outcomes in curatively resected pancreatic and periampullary adenocarcinoma(Chinese Journal Cancer Research Co, 2015) Turan, Nedim; Benekli, Mustafa; Unal, Olcun Umit; Unek, Ilkay Tugba; Tastekin, Didem; Dane, Faysal; Algin, EfnanBackground: We examined the impact of adjuvant modalities on resected pancreatic and periampullary adenocarcinoma (PAC). Methods: A total of 563 patients who were curatively resected for PAC were retrospectively analyzed between 2003 and 2013. Results: Of 563 patients, 472 received adjuvant chemotherapy (CT) alone, chemoradiotherapy (CRT) alone, and chemoradiotherapy plus chemotherapy (CRT-CT) were analyzed. Of the 472 patients, 231 were given CRT-CT, 26 were given CRT, and 215 were given CT. The median recurrence-free survival (RFS) and overall survival (OS) were 12 and 19 months, respectively. When CT and CRT-CT groups were compared, there was no significant difference with respect to both RFS and OS, and also there was no difference in RFS and OS among CRT-CT, CT and CRT groups. To further investigate the impact of radiation on subgroups, patients were stratified according to lymph node status and resection margins. In node-positive patients, both RFS and OS were significantly longer in CRT-CT than CT. In contrast, there was no significant difference between groups when patients with node-negative disease or patients with or without positive surgical margins were considered. Conclusions: Addition of radiation to CT has a survival benefit in patients with node-positive disease following pancreatic resection.Öğe Lapatinib plus Capecitabine for Brain Metastases in Patients with Human Epidermal Growth Factor Receptor 2-Positive Advanced Breast Cancer: A Review of the Anatolian Society of Medical Oncology (ASMO) Experience(Karger, 2012) Cetin, Bulent; Benekli, Mustafa; Oksuzoglu, Berna; Koral, Lokman; Ulas, Arife; Dane, Faysal; Turker, IbrahimBackground: We investigated the clinical outcome of patients with brain metastases (BMs) from human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC) treated with lapatinib and capecitabine (LC). Patients and Methods: A total of 203 patients with HER2+ MBC, who had progressed after trastuzumab-containing chemotherapy, were retrospectively evaluated in 11 centers between September 2009 and May 2011. 85 patients who had developed BMs before the initiation of treatment with LC were included. All patients had received prior cranial radiotherapy. All patients were treated with the combination of lapatinib (1,250 mg/day continuously) and capecitabine (2,000 mg/m(2) on days 1-14 of a 21-day cycle). Results: The median follow-up was 10.5 months (range 1-38 months). An overall response rate of 27.1% was achieved, including complete response in 2 (2.4%) and partial response in 21 (24.7%) patients. Median progression-free survival was 7 months (95% confidence interval (CI) 5-9), with a median overall survival of 13 months (95% Cl 9-17). The most common side effects were hand-foot syndrome (58.8%), nausea (55.3%), fatigue (48.9%), anorexia (45.9%), rash (36.5%), and diarrhea (35.4%). Grade 3-4 toxicities were hand-foot syndrome (9.4%), diarrhea (8.3%), fatigue (5.9%), and rash (4.7%). There were no symptomatic cardiac events. Conclusion: LC combination therapy was effective and well-tolerated in patients with HER2+ MBC with BMs, who had progressive disease after trastuzumab-containing therapy.Öğe Lapatinib plus capecitabine for HER2-positive advanced breast cancer: a multicentre study of Anatolian Society of Medical Oncology (ASMO)(Taylor & Francis Ltd, 2014) Cetin, Bulent; Benekli, Mustafa; Turker, Ibrahim; Koral, Lokman; Ulas, Arife; Dane, Faysal; Oksuzoglu, BernaLapatinib is the first dual tyrosine kinase inhibitor of human epidermal growth factor receptor type 2 (HER2/neu) and epidermal growth factor receptor (EGFR). The present study evaluated the efficacy and tolerability of the combination of lapatinib and capecitabine in patients with metastatic breast cancer (MBC) who progressed after therapy with trastuzumab, a taxane and/or anthracycline. A total of 203 patients with a median age of 48 years (range: 25-82 years) were evaluated retrospectively in 11 centres between September 2007 and May 2011. All the patients had HER2-positive MBC progressing after trastuzumab and chemotherapy including an anthracycline and/or taxane. All patients were treated with the combination of lapatinib (1250 mg/day, continuously) and capecitabine (2000 mg/m(2) on days 1 through 14 of a 21-day cycle). Data on demographics, clinical outcome, and toxicity were collected for descriptive analyses. The median follow-up was 10.7 months (range: 1-40 months). An overall response rate (ORR) of 33.4% was achieved including 7 complete responses (CR, 3.4%), 61 partial responses (PR, 30.0%), and 44 stable disease (37.9%). Clinical benefit rate of 71.3% was achieved. Median progression-free survival (PFS) was 7 months (95% CI: 6-10 months), with a median overall survival (OS) of 15 months (95% CI: 12-18 months). The most common side effects were hand-foot syndrome (46.8%), nausea (42.3%), fatigue (42.2%), anorexia (38.5%), diarrhea (31.5%), and rash (29.6%). Grade 3-4 toxicities were identified as hand foot syndrome (7.9%), diarrhea (6.9%), fatigue (5.9%), and rash (5.4%). There were no symptomatic cardiac events. Lapatinib and capecitabine combination therapy is effective and well tolerated in patients with MBC who had progressive disease after trastuzumab, taxane, and/or anthracycline therapy, as evidenced by this retrospective evaluation. Toxicity was mild to moderate with low grade 3-4 toxicity.Öğe The prognostic value of lymph node ratio in patients with curatively resected pancreatic adenocarcinoma.(Amer Soc Clinical Oncology, 2015) Turan, Nedim; Araz, Murat; Algin, Efnan; Unal, Olcun Umit; Benekli, Mustafa; Tastekin, Didem; Dane, Faysal[Abstract Not Available]Öğe Results of Adjuvant FOLFOX Regimens in Stage III Colorectal Cancer Patients: Retrospective Analysis of 667 Patients(Karger, 2013) Uncu, Dogan; Aksoy, Sercan; Cetin, Bulent; Yetisyigit, Tarkan; Ozdemir, Nuriye; Berk, Veli; Dane, FaysalObjective: The aim of this study was to assess the use of 5-fluorouracil (5-FU), leucovorin and oxaliplatin (FOLFOX) regimens in clinical practice according to their efficacy and toxicity. Methods: Patients who received oxaliplatin-containing regimens after curative resection for colorectal carcinoma from 10 different oncology centers between May 2004 and December 2009 were included in the study. All patients were treated with FOLFOX regimens. Patients with rectal carcinoma were also treated with chemoradiotherapy with 5-FU after 2 cycles of a FOLFOX regimen. Results: The median age of the patients was 56 years (range 17-78). Of the total 667 patients, 326 were given FOLFOX-4, 232 were given modified FOLFOX-4 and 109 were given FOLFOX-6. The distribution according to disease stage was 33 patients with stage IIIA colorectal cancer, 382 patients with stage IIIB and 252 patients with stage IIIC. The most common adverse events were neutropenia (54%), nausea (36.9%), neuropathy (38.2%) and anemia (33.1%) for all grades. The median follow-up time was 23 months (range 1-79). Three-year disease-free survival and overall survival were 65 and 85.7%, respectively. Conclusion: The different oxaliplatin-containing 5-FU-based adjuvant chemotherapy regimens in patients with stage III colorectal cancer seemed to be at least equal in terms of efficacy regardless of the method of 5-FU administration or oxaliplatin dose.

Karger AG, BaselÖğe Results of observational study to determine K-ras mutation rates in 2458 patients with metastatic colorectal cancer in Turkey (TURKRAS Study).(Amer Soc Clinical Oncology, 2015) Gumus, Mahmut; Dane, Faysal; Karabulut, Bulent; Uygun, Kazim; Aydin, Kubra; Orhan, Bulent; Oksuzoglu, Berna[Abstract Not Available]Öğe Third-line Therapy for Metastatic Renal Cell Carcinoma and Its Effect on Quality of Life and Overall Survival: A National, Multicenter, Observational Study(2020) Çiçin, İrfan; Çiltaş, Aydın; Kılıçkap, Saadettin; Öksüzoğlu, Ömür; Uncu, Doğan; Artaç, Mehmet; Çınkır, Havva; Işıkdoğan, Abdurrahman; Dane, Faysal; Aliustaoğlu, Mehmet; Türk, Hacı Mehmet; Elkıran, Emin; Çubukçu, Erdem; Ekenel, Meltem; Özdemir, Feyyaz; Gökyer, Ali; Öztop, İlhan; Alacacıoğlu, Ahmet; Öztürk, Hüseyin; Aver, Birkan; Özkan, MetinAbstract: Objective: Chronic antigenic stimulation is frequently blamed in the pathogenesis of extranodal marginal zone lymphomas including splenic marginal zone lymphoma (SMZL). Chronic hepatitis C is frequently observed in SMZL patients in some geographical regions. However, these reports are largely from North America and Europe, and data from other countries are insufficient. In this multicenter study we aimed to identify the clinical characteristics of SMZL patients in Turkey, including viral hepatitis status and treatment details. Materials and Methods: Data were gathered from participating centers from different regions of Turkey using IBM SPSS Statistics 23 for Windows. Hepatitis B virus surface antigen (HBsAg), anti-HBs antibody, anti-HB core antigen antibody (anti-HBcAg), HB viral load, anti-hepatitis C virus (HCV) antibody, HCV viral load results were analyzed. Results: One hundred and four patients were reported. Hepatitis C virus positivity was observed in only one patient. However, hepatitis B virus surface antigen (HBsAg) positivity was observed in 11.2% and HBsAg and/or anti-HB core antigen antibody (anti-HBcAg) positivities were seen in 34.2% of the patients. The median age was 60 years (range=35-87). Median follow-up duration was 21.2 months (range=00.2-212; 23.2 months for surviving patients). Median overall survival was not reached. Estimated 3-year and 10-year survival rates were 84.8% and 68.9%, respectively. Older age, no splenectomy during follow-up, platelet count of <90x103/µL, lower albumin, higher lactate dehydrogenase, higher ?2-microglobulin, and HBsAg positivity were associated with increased risk of death. Only albumin remained significant in multivariable analysis. Conclusion: These results indicate that hepatitis B virus may be a possible risk factor for SMZL in our population. It may also be an indirect prognostic factor.Öğe Tyrosine kinase inhibitors in the treatment of metastatic renal cell cancer patients with early cytokine intolerance: TURCOS, a Turkish national, prospective observational study(Sage Publications Ltd, 2021) Benekli, Mustafa; Gumus, Mahmut; Ozkan, Metin; Dane, Faysal; Elkiran, Emin T.; Cicin, Irfan; Sevinc, AlperObjective Cytokines have been the mainstay of treatment in metastatic renal cell cancer (mRCC) for decades before the introduction of tyrosine kinase inhibitors (TKIs), which dramatically changed the therapeutic landscape in these patients. This observational study was designed to evaluate use of TKIs in the treatment of cytokine-intolerant mRCC patients. Methods A total of 151 cytokine-intolerant mRCC patients who were treated with TKIs (sunitinib, pazopanib and sorafenib) were enrolled in this prospective, non-interventional, multi-center observational study at 16 oncology centers across Turkey. Mean (SD) age was 61.3 (11.1) years and 74.8% were males. Data on duration of TKI treatment was the primary outcome measure. Additionally, overall response rate (ORR), progression free survival (PFS), overall survival (OS) and safety data were recorded. Results Median duration of treatment was 8.2 months at a median follow up of 17.9 months. ORR and disease control rate were 12.5% and 70.8%, respectively. Median PFS and OS were 7.5 months (95%CI: 6.4-10.4) and 27.3 months (95%CI: 17.6-27.3) with no significant difference among three TKI agents in terms of treatment duration, ORR, PFS and OS. The most common adverse events excluding progression-which was the protocol requirement were diarrhea (13.6%), asthenia (13.6%) and hand-foot syndrome (12.6%). Dose modifications were required in 30.5% of the patients and 15% discontinued TKIs because of toxicity. Conclusions Our findings confirm the efficacy and safety profile of TKIs in the first-line treatment of mRCC patients intolerant to cytokine treatment. There was no significant difference among three TKI agents in terms of treatment duration, ORR, PFS and OS.
