    Differences in PET/CT standardized uptake values involvement and survival compared to histologic subtypes of lung adenocarcinoma
    (SAGE PUBLICATIONS LTD, 2021) BOZKURTLAR, EMİNE; Ercelep, Ozlem; Alan, Ozkan; Telli, Tugba A.; Tuylu, Tugba B.; Arikan, Rukiye; Demircan, Nazim Can; Simsek, Eda T.; Babacan, Nalan A.; Kaya, Serap; Dane, Faysal; Bozkurtlar, Emine; Ones, Tunc; Lacin, Tunc; Yumuk, Perran Fulden
    Purpose: Lung adenocarcinoma is histologically diverse but has distinct histologic growth patterns. There is no consensus on the clinical benefit of this histologic model. We aimed to evaluate the differences in the distribution of the preoperative primary tumor positron emission tomography (PET)/computed tomography (CT) standardized uptake values (SUVs) and survival in the lung adenocarcinoma subtypes. Methods: We retrospectively evaluated the data of 107 patients with resected lung adenocarcinoma who had preoperative PET/CT between 2005 and 2017 in a single center. Patients had lepidic, acinar, papillary, micropapillary, and solid histologic subtypes. We compared fluorodeoxyglucose SUVs and survival data of histologic subtypes. Results: The median age of the patients was 62 years (40-75), 76.4% were male, the median SUVmax was 9.4 (1-36.7), and the median follow-up time was 29 months (3-135 months). The median overall survival (OS) was 71 months and the median progression-free survival (PFS) was 33 months. SUVmax was significantly different in histologic subtypes: values for papillary, micropapillary, solid, acinar, and lepidic subtypes were 9.7, 8, 12, 9.1, and 3.9, respectively (p= 0.000). Solid predominant adenocarcinoma had significantly higher SUVmax than the other subtypes (p= 0.001). Lepidic predominant adenocarcinoma had significantly lower SUVmax than the other subtypes (p= 0.000). There was no significant difference in OS between histologic subtypes (p= 0.66), but PFS was significantly different between the groups (p= 0.017), and the solid subtype had a shorter PFS than the other histologic subtypes. Conclusion: Lung adenocarcinoma consists of a diverse group of diseases. Different SUVmax values are seen in different histologic subtypes of nonmetastatic lung adenocarcinoma. Solid predominant types have high SUVmax values while lepidic predominant types have lower SUVmax values. The solid subtype had a shorter PFS than the other histologic subtypes.

    Pulmonary artery sarcoma treated with pulmonary endarterectomy and leaflet reconstruction using Ozaki technique
    (2022-11-01) AK, KORAY; ÖZTÜRK, FATİH; BOZKURTLAR, EMİNE; ARSAN, SİNAN; YILDIZELİ, BEDRETTİN; Arslanhan G., AK K., Ozturk F., Turker A., BOZKURTLAR E., ARSAN S., YILDIZELİ B.
    Pulmonary arterial intimal sarcomas (PAIS) are rare malignancies with a poor prognosis. Sarcomas present with signs and symptoms mimicking pulmonary thromboembolic disease, delaying the diagnosis. We present a 29-year-old male patient diagnosed with PAIS in the right and main pulmonary arteries extending to the left pulmonary leaflet. The patient was treated with pulmonary endarterectomy and pulmonary leaflet reconstruction using the Ozaki technique.

    Should We Perform Thoracic Imaging for Every Patient with a Renal Mass?
    (GALENOS YAYINCILIK, 2016-09-23) BOZKURTLAR, EMİNE; Sahan, Ahmet; Garayev, Asgar; Akgul, Murat; Sener, Tarik Emre; Evman, Serdar; Batirel, Hasan; Bozkurtlar, Emine Bas; Ahiskali, Rengin; Turkeri, Levent; Tinay, Ilker
    Objective: Current guidelines for the management of renal mass recommend thoracic imaging for potential metastatic nodules. Small size of the renal mass can be associated with low metastatic potential, which might question the necessity of thoracic imaging in this patient population. This study sought to evaluate the association of thoracic imaging findings with the renal mass characteristics in patients with pathologically proven renal cell carcinoma (RCC). Materials and Methods: We performed a retrospective analysis of patients with RCC, who underwent radical/partial nephrectomy and had baseline thoracic imaging available for review. Patients with a suspicious pulmonary mass were evaluated by the Department of Thoracic Surgery. Presence of lung nodule(s) and metastasis was determined and compared with patient and renal mass characteristics. Results: A total of 215 patients were included in the study. Pulmonary nodules suspicious for malignancy were present in 26.8% of the cases and 42% of these patients underwent further examination for the presence of a pulmonary mass. Pathological examination of the pulmonary nodule revealed RCC metastasis in 80% of patients who underwent biopsy or excision of the pulmonary nodule. Of note, in the subgroup analysis according to the pathological stage of the renal mass, 19.3% of patients with pT1a disease had a suspicious pulmonary mass on thoracic imaging. Of these patients, 25% underwent further examination of the pulmonary nodule with a RCC metastasis in 66.6%. Conclusion: The presence of suspicious lung nodules in patients with RCC has metastatic potential regardless of the size of the renal mass. These findings underscore the importance of baseline thoracic imaging and vigilant further evaluation of patients in whom pulmonary nodules are identified.
