In this study, we evaluated the general characteristics of patients, the difficulties experienced during and after lung cancer surgery and complications and mortality rates.Method Patients who were operated on for primary lung cancer between January 2012 and July 2017 in the participating centres were analysed retrospectively (n=7,530). Patients with a history of CABG (n=220) were examined in detail. This special group was analysed and compared with other patients operated on for lung cancer who did not have CABG (n=7,310) in terms of 30-day mortality and revision for haemorrhage.Results Of the 7,530 patients operated on for primary lung cancer, 2.9% were found to have undergone CABG. Surgical revision was required in the early postoperative period for 6.8% of those who had CABG and 3.5% in those who did not have CABG (p=0.009). Thirty-day (30-day) mortality was 4.5% in those who had CABG and 2.9% in those who did not have CABG (p=0.143). Further analysis of patients who had undergone CABG demonstrated that video-assisted thoracoscopic surgery (VATS) resulted in fewer complications (p=0.015). Patients with a left-sided left internal mammary artery (LIMA) graft had a higher number of postoperative complications (p=0.30).Conclusions Patients who had CABG suffered postoperative haemorrhage requiring a revision twice as often, and a tendency towards higher mortality (non-statistically significant). In patients with a history of CABG, VATS was demonstrated to have fewer complications. Patients with a LIMA graft who had a left-sided resection had more postoperative complications.Publication A case of spontaneous pneumomediastinum with unknown etiology(Derman Medical Publ, 2019-03-01) Alar, Timucin; Gedik, Ismail Ertugrul; Bayram, Ahmet Sami; BAYRAM, AHMET SAMİ; Tıp Fakültesi; 0000-0002-4719-002X; 0000-0003-0684-0900; ABB-7580-2020First described by Hamman in 1939, spontaneous pneumomediastinum (SPM) is a disease with the collection of air in the mediastinum without any underlying cause. It is usually seen in young males and its incidence is reported between 1/15000-1/25000 in different case series. We would like to present the case of a 16-year-old male patient who admitted to our hospital with the complaints of pleuritic chest pain and tenderness in the neck and was diagnosed as spontaneous pneumomediastinum. Patient spontaneously recovered without the need of an invasive procedure.Publication Thymic tumors and outcomes after radiotherapy(Kare Yayın, 2013-01-01) Sarıhan, Süreyya; Bayram, Ahmet Sami; Gebitekin, Cengiz; Yerci, Ömer; Özkan, Lütfi; SARIHAN, SÜREYYA; BAYRAM, AHMET SAMİ; GEBİTEKİN, CENGİZ; YERCİ, ÖMER; Özkan, Lütfi; Tıp Fakültesi; Göğüs Cerrahisi Ana Bilim Dalı; 0000-0003-4816-5798; 0000-0003-0684-0900; AAE-1069-2022; ABB-7580-2020; AAH-4970-2021; EIS-5114-2022; JGQ-9310-2023OBJECTIVESWe evaluated the results of treatment in patients with thymic tumors treated with postoperative adjuvant radiotherapy.METHODSEighteen patients were treated median 5400 cGy radiotherapy between 1995-2010. Diagnosis of patients were thymoma (n=10), thymic carcinoma (n=7), thymic neuroendocrin carcinoma (n=1). RO resection was made on 12 of them. According to prognostic stratification with Masaoka stage and WHO classification, there were 5 good, 7 moderate, and 6 poor risk patients. Survival was calculated from diagnosis.RESULTSA total of 33% patients were recurred median 29.5 months with 34 months follow-up. Local control, median overall and disease-free survival for all patients were 77%, 113 months, and 105 months. Local control for good, moderate, poor risk groups were found 100%, 71%, 50%. There were significant differences survival rates for Masaoka stage, RO resection, and prognostic groups.CONCLUSIONPrognostic risk classification was found to be better predictive in terms of local control and survival.Publication Comparison of survival results of patients with t0 and t1-2-3 in pathological t staging in patients with non-small cell lung cancer who underwent surgery after neoadjuvant treatment(Termedia Publishing House, 2020-01-01) Kermenli, Tayfun; Melek, Hüseyin; Bayram, Ahmet Sami; Gebitekin, Cengiz; MELEK, HÜSEYİN; BAYRAM, AHMET SAMİ; GEBİTEKİN, CENGİZ; Tıp Fakültesi; 0000-0003-0684-0900; 0000-0003-1822-8153; AAE-1069-2022; AAI-5039-2021; JCE-0097-2023; ABB-7580-2020Aim: In this study, we aimed to compare the survival results of patients who underwent neoadjuvant treatment with NSCLC between March 1997 and August 2014 and were found to have T0N0 and T1-2-3/N0.Material and methods: A hundred ninety-five patients who had complete neoadjuvant therapy, complete lung resection and lymph node dissection, and pathologically diagnosed as T0 or T1-2-3/N0, M0 were included in the study.Results: Of the 195 patients included in the study, 181 were male, 14 were female and the mean age of the patients was 57.9. The mean age of the groups was as follows: group 1: 58.1, group 2: 57.7, group 3: 59.7 and group 4: 56.8. In our series the most common complication was atelectasis (n = 19). Others were prolonged air leak (n = 16), pneumonia (n = 12), apical pleural space (n = 6), wound infection (n = 3), cardiac problems (n = 3), hematoma (n = 3), bronchopleural fistula (n = 3), empyema (n = 2), chylothorax (n = 1). The 5-year survival rate for patients in the T0N0 group was 76.3%. This rate was 71.8% in group 2, 63.6% in group 3 and 44.1% in group 4.Conclusions: Survival was found to be better in patients who underwent surgery after neoadjuvant therapy and had a complete pathological response. We believe that we can provide better results with the increase in the number of cases detected as TxN0 after the neoadjuvant treatment and prolongation of the follow-up period.Publication Gastrointestinal stromal tumor of the esophagus: Report of a case(Derman Medical Publ, 2016-01-01) GEBİTEKİN, CENGİZ; Erol, M.

Clinical and categorical variables were analyzed.RESULTSOn multivariate analysis, presence of clinical N2 and brain metastasis at first relapse and absence of chemotherapy (p=0.02, p=0.004, p=0.004) had a negative impact on overall survival, while presence of pathological nodal involvement and absence of chemotherapy (p=0.02, p=0.04) were effective on disease-free survival. Regarding categorical variables, type of resection was found related with positive margin and N1, right-sided location with N1-e and N2, and systematic nodal dissection with N1. The number of involved lymph nodes was found related with N2 skip metastasis and involved N1-10 was related with N1-e.CONCLUSIONPresence of metastatic lymph nodes was found to be a poor prognostic factor and delivery of chemotherapy was seen to positively affect overall and disease-free survival rates.Publication Platin-based chemotherapy does not improve survival in patients with non-metastatic resected typical carcinoid tumors(Spandidos Publ Ltd, 2022-10-01) Şahin, Ahmet Bilgehan; Melek, Hüseyin; Ocak, Birol; Oyucu Orhan, Sibel; Erkan, Buket; Caner, Burcu; Deligönül, Adem; Çubukcu, Erdem; Bayram, Ahmet Sami; Akyıldız, Elif Ülker; Evrensel, Türkkan; ŞAHİN, AHMET BİLGEHAN; MELEK, HÜSEYİN; OCAK, BİROL; OYUCU ORHAN, SİBEL; ERKAN ÖZMARASALI, BUKET; CANER, BURCU; DELİGÖNÜL, ADEM; ÇUBUKÇU, ERDEM; BAYRAM, AHMET SAMİ; AKYILDIZ, ELİF ÜLKER; EVRENSEL, TÜRKKAN; Tıp Fakültesi; Tıbbi Onkoloji Ana Bilim Dalı; 0000-0002-7846-0870; 0000-0003-0684-0900; 0000-0003-1822-8153; 0000-0001-8217-3471; 0000-0003-1591-3323; AAM-4927-2020; AAI-5039-2021; AEC-2238-2022; AAJ-8314-2021; CPN-8681-2022; HJH-6371-2023; ESM-4544-2022; ETP-1691-2022; ABB-7580-2020; ELN-4128-2022; EXZ-0745-2022Chemotherapy is controversial in non-metastatic typical carcinoid (TC) tumors. Therefore, it was aimed to evaluate the impact of platin-based chemotherapy on the survival of patients with lung TC. The medical records of patients who underwent surgical resection for non-metastatic TC from 2002 to 2020 at our institution were retrospectively reviewed. Multivariate regression analysis was performed for chemotherapy and prognostic factors in disease-free survival (DFS) in 72 patients. The pathological stages of patients were as follows: 73.6% of the patients were in stage I, 15.3% in stage II and 11.1% in stage III. A total of 5 patients (6.9%) received platin-based chemotherapy and 6 patients (8.3%) had recurrences. The DFS rates at 12, 36 and 60 months were 98.5, 95.1 and 92.5%, respectively. Log-rank testing showed that patients who received chemotherapy and had stage III disease had shorter DFS (P=0.021 for chemotherapy and P<0.001 for stage). However, multivariate analysis revealed that the pathological stage was the only statistically significant factor affecting DFS (P=0.016). Platin-based chemotherapy did not improve DFS, and the eighth edition of TNM (tumor, nodes, metastases) staging did have prognostic value for patients with non-metastatic TC. Although resection has satisfying long-term outcomes, studies on new agents are needed to decrease the recurrence rate, particularly in patients with stage III disease.Publication Can thoracic sympathetic nerve damage be reversed?(Georg Thieme Verlag, 2015-12-01) Erol, M.

Hence, this study was designed to study nerve regeneration after unclipping the TSC.Methods The bilateral TSCs of six goats were studied; the goats were separated into three groups (groups I, II, and III) during excision, clipping, and unclipping. During surgery, the TSCs were excised with a scalpel in group I and clipped in groups II and III. In group III, the clips were removed 1 month postoperatively and observed for possible nerve healing for 1 month. All TSCs were examined histologically following en block resection at 1 month postoperatively in groups I and II and at 2 months postoperatively in group III.Results Inflammation in nerve sections was noted following clip removal. Furthermore, there was significant degeneration and cell infiltration in the nerve fibers of the clipped regions. The Schwann cells around the peripheral nerve endings in the unclipped regions facilitated nerve transmission by reconstitution of myelin.Conclusion Clipping the TSC can cause histologic degeneration; however, histologic nerve regeneration occurs after unclipping.
