Publication Relationship between PET/CT response and survival in patients with non-small-cell lung cancer treated with definitive chemoradiotherapy(Akad Doktorlar Yayınevi, 2021-01-01) Sarıhan, Süreyya; Bilgin, Gökçe Belge; Sığırlı, Deniz; SARIHAN, SÜREYYA; Bilgin, Gökçe Beige; SIĞIRLI, DENİZ; Tıp Fakültesi; Nükleer Tıp Ana Bilim Dalı; 0000-0003-4816-5798; AAH-4970-2021; AAA-7472-2021; EMG-1218-2022We aimed to evaluate the relationship between PET/CT response and survival in patients with non-small cell lung cancer (NSCLC) treated with curative chemoradiotherapy. Between January and December 2012, 51 patients were treated. The median age was 61 (29-79) and the M/F ratio was 46/5. Eighty two percent of the cases were stage III and 53% were squamous cell carcinoma. Median 6300 cGy (4860-7525) radiotherapy delivered and 92% of patients received chemotherapy. The median follow-up was 27 months (7-96 months) in November 2019. The objective response was 71% with CT at 1 month and 76% with PET/CT at 3 months. There was a significant correlation between response-1 and response-3 (p< 0.001). Tumor SUVmean3 < 2.81, SUVmax change >= 70% was associated with response-1 (p< 0.05). The median and 5-year overall (OS) and progression-free (PFS) survival rates were 54 months, 40% and 35 months, 38%, respectively. In Cox model, for each 1 unit increase, SUVmeanbase (HR: 1.18, 95% CI: 1.01-1.38) and SUVmean3 (HR: 2.65, 95% CI: 1.24-5.66) were found unfavorable factors for OS, whereas SUVmean3 (HR: 2.01, 95% CI: 1.02-3.93) was also found to be a poor prognostic factor for PFS. PET/CT parameters can be used as useful markers for prognosis in patients with NSCLC undergoing curative chemoradiotherapy. It is believed that early assessment during and after treatment can be advantageous in terms of treatment modification.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 Lung cancer: Elective nodal irradiation(Kare, 2012-01-01) Sarıhan, Süreyya; SARIHAN, SÜREYYA; Tıp Fakültesi; Radyasyon Onkoloji Ana Bilim Dalı; 0000-0003-4816-5798; AAH-4970-2021The goal of the treatment for lung cancer is to obtain local control, and as a result, to improve survival. In order to treat potentially subclinical disease, delivery of 40-50 Gy radiotherapy (RT) to the regional-nodal areas is designated as elective nodal irradiation (ENI). Increasing the volume of irradiated normal tissues with this approach leads to greater toxicity and prevents successful dose escalation. Advances in the staging of mediastinal disease and lower-than-expected elective nodal failure rates with involved nodal RT led to questions regarding the use of ENI, specifically, what is the target volume for postoperative irradiation? Restricted target volume usage with modem RT techniques has led to a negative effect on regional control due to inter- and intra-fraction motions, and it is questionable whether selective ENI is reasonable in curative treatment. This review evaluates the changes concerning the use of ENI over time.Publication Evaluation of prognostic factors on survival in non-small-cell lung cancer patients treated with postoperative radiotherapy(Kare Publ, 2009-01-01) Sarıhan, Süreyya; SARIHAN, SÜREYYA; Gebitekin, Cengiz; ERCAN, İLKER; GEBİTEKİN, CENGİZ; Bayram, Ahmet Sami; BAYRAM, AHMET SAMİ; EVRENSEL, TÜRKKAN; Evrensel, Turkkan; Akyıldız, Elif Ülker; AKYILDIZ, ELİF ÜLKER; Tıp Fakültesi; Biyoistatistik Ana Bilim Dalı; 0000-0003-4816-5798; 0000-0003-0684-0900; 0000-0002-2382-290X; ABB-7580-2020; AAJ-1027-2021; JCE-0097-2023; AAH-4970-2021; AAE-1069-2022OBJECTIVESTo investigate the prognostic factors on survival in non-small-cell lung cancer patients treated with postoperative radiotherapy.METHODSSixty-five patients treated with a median dose of 59 Gy (50-66.6 Gy) between October 1995 and January 2005 were included in the study. 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 Gliosarcomas: Analysis of 9 cases treated with radiotherapy(Elsevier Ireland Ltd, 2008-09-01) Edincik, C.; Sarıhan, S.; Yıldırım, S.; Kurt, M.; Çetintaş, S.; Doğan, S.; Tolunay, S.; Edincik, C.; SARIHAN, SÜREYYA; Yıldırım, S.; KURT, MERAL; ÇETİNTAŞ, SİBEL; Doğan, Selda; TOLUNAY, ŞAHSİNE; Tıp Fakültesi; Beyin Cerrahisi Ana Bilim Dalı; 0000-0003-4816-5798; 0000-0003-2589-8585; AAA-7047-2020; AAH-4970-2021; I-7575-2015; AAI-1612-2021; AAA-3961-2020; EWI-7826-2022; EFX-2827-2022Publication The survival effect of resection of cranial metastatic lesions in patients with lung cancer(Elsevier Science, 2015-09-01) Deligönül, Adem; Taşkapılıoğlu, Özgür; Melek, Hüseyin; Bekar, Ahmet; Çetinkaya, Gamze; Sarihan, Süreyya; Bayram, Ahmet Sami; Gebitekin, Cengiz; Evrensel, Türkkan; DELİGÖNÜL, ADEM; TAŞKAPILIOĞLU, MEVLÜT ÖZGÜR; MELEK, HÜSEYİN; BEKAR, AHMET; Çetinkaya, Gamze; SARIHAN, SÜREYYA; BAYRAM, AHMET SAMİ; GEBİTEKİN, CENGİZ; EVRENSEL, TÜRKKAN; Tıp Fakültesi; İç Hastalıkları Ana Bilim Dalı; Tıbbi Onkoloji Bilim Dalı; 0000-0001-5472-9065; 0000-0003-4816-5798; 0000-0003-0684-0900; AAI-5039-2021; ABX-9081-2022; AAH-4970-2021; AAE-1069-2022; JDW-2654-2023; AAJ-1027-2021; JCE-0097-2023; ABB-8161-2020; ABB-7580-2020Publication Relationship between pet/ct response and survival in patients with non-small-cell lung cancer treated with definitive chemoradiotherapy(Akad Doktorlar Yayınevi, 2021-01-01) Sarıhan, Süreyya; Bilgin, Gökçe Beige; Sığırlı, Deniz; SARIHAN, SÜREYYA; Bilgin, Gökçe Beige; SIĞIRLI, DENİZ; Tıp Fakültesi; Radyasyon Onkolojisi Ana Bilim Dalı; 0000-0003-4816-5798; AAH-4970-2021; EMG-1218-2022; AAA-7472-2021We aimed to evaluate the relationship between PET/CT response and survival in patients with non-small cell lung cancer (NSCLC) treated with curative chemoradiotherapy.

Their median age was 37 years (15-53). The diagnosis was adenoid cystic carcinoma in five patients, squamous cell carcinoma in three patients and mucoepidermoid carcinoma in one patient. Resection type was R0 (1), R1 (4), R2 (1), and biopsy (2). The median tumour size was 2.6 cm (2-5). Median 59.4 Gy RT (32.4-66.6) was given, and weekly cisplatin was administered to four patients concomitantly.RESULTSWith a median follow-up of 85 months (4-189), five patients were alive. The 5-year overall and disease-free survival rates were 83% and 67%, respectively. There was no local recurrence in any patient. In one patient who had a complete response with curative chemo-RT, dilatation was performed five times in 10 years because tracheal stenosis developed at 60 months.CONCLUSIONTrachea tumours are rare, and the primary treatment is surgery. Adjuvant RT is controversial in R0 cases. In unresectable cases, RT is the primary treatment modality. We believe that our treatment results will contribute to the literature on the subject.
