    Prognostic effects of predominant histologic subtypes in resected pulmonary adenocarcinomas
    (Galenos Publishing House, 2019) Yaldız D.; Kaya Ş.Ö.; Ceylan K.C.; Acar A.; Aydoğdu Z.; Gürsoy S.; Yaldız S.
    Background: Predominant histologic subtypes have been reported as predictors of survival of patients with pulmonary adenocarcinoma. Aims: To evaluate the predictive value of histologic classification in resected lung adenocarcinoma using the classification systems proposed by the International Association for the Study of Lung Cancer, American Thoracic Society, European Respiratory Society, and World Health Organization (2015). Study Design: Cross-sectional study. Methods: The histologic classification of a large cohort of 491 patients with resected lung adenocarcinoma (stages I-III) was retrospectively analyzed. The tumors were classified according to their predominant component (lepidic, acinar, papillary, solid, micropapillary, and mucinous), and their predictive values were assessed for clinicopathologic characteristics and overall survival. Results: The patient cohort comprised 158 (32.2%) patients with solid predominant, 150 (30.5%) with acinar predominant, 80 (16.3%) with papillary predominant, 75 (15.3%) with lepidic predominant, 22 (4.5%) with mucinous, and 5 (1.0%) with micropapillary subtype, and 1 (0.2%) with adenocarcinoma in situ. Overall 5-year survival of 491 patients was found to be 51.8%. Patients with lepidic, acinar, and mucinous adenocarcinoma had 70.9%, 59.0%, and 66.6% 5-year survival, respectively, and there was no statistically significant difference between them. Whereas patients with solid, papillary, and micropapillary predominant adenocarcinoma had 41.0%, 40.5%, and 0.0% 5-year survival, respectively. Compared to other histologic subtypes, patients with solid and papillary predominant adenocarcinoma had significantly lower survival than those with lepidic (p<0.001, p=0.002), acinar (p<0.001, p=0.008), and mucinous (p=0.048, p=0.048) subtypes, respectively. The survival difference between patients with solid subtype and those with papillary subtype was not statistically significant (p=0.67). Conclusion: Solid and papillary histologic subtypes are poor prognostic factors in resected invasive lung adenocarcinoma. © 2019 by Trakya University Faculty of Medicine / The Balkan Medical Journal published by Galenos Publishing House.

    A rare complication of video-assisted thoracoscopic surgery: Lung herniation retrospective case series of three patients and review of the literature
    (Termedia Publishing House Ltd., 2020) Batıhan G.; Yaldız D.; Ceylan K.C.
    Introduction: Lung herniation is defined as a protrusion of the lung parenchyma with its pleura through the intercostal space. It is a rare condition and usually occurs after thoracic trauma and surgical interventions. A few cases of lung herniations have been reported after video-assisted thoracoscopic surgery (VATS) but only two cases have been reported after VATS lobectomy. Aim: The VATS procedure has become the dominant method of lung cancer surgery, but there is no case series about the complications of lung herniation in the literature. We aim to define some risk factors and possible ways of prevention of lung herniation after VATS resection. Material and methods: This study retrospectively analyses 650 (550 anatomic, 100 non-anatomic sublobar resections) patients who underwent lung resections for lung cancer in our department between 2012 and 2018. We detected lung herniation in 3 patients after VATS resection. Results: Asymptomatic lung hernias may be managed by close observation but because of the risk of incarceration of the pulmonary parenchyma, surgery is often necessary. The main steps of treatment involve: identification of the hernia, freeing of all adhesions, reduction of the lung tissue back into the thoracic cavity and repairing the defect of the chest wall. Conclusions: By this retrospective case series, we defined some patient-related and surgeon-related risk factors and some basic recommendations for prevention of this complication. © 2020 Termedia Publishing House Ltd..

    Pitfalls in the surgical treatment of undiagnosed lung lesions and cystic pulmonary hydatidosis
    (BioMed Central Ltd, 2022) Yaldız D.; Batıhan G.; Ceylan K.C.; Yaldız S.; Susam S.
    Background: Hydatid cysts can mimic many lung pathologies radiologically, as well as some malignant or benign lung tumors may show hydatid cyst-like radiological features. The aim of our study is to present our clinical experience and recommendations by analyzing the cases that create diagnostic difficulties by presenting a common radiological pattern with a pulmonary hydatid cyst. Methods: The patients who were operated on with a preliminary diagnosis of hydatid cyst but were diagnosed differently, and who were operated on with different prediagnoses and unexpectedly diagnosed with hydatid cyst were included in the study. The clinical and radiological features of the patients were documented, and the features of the cases that could cause difficulties in diagnosis and treatment for the surgeon were revealed. Results: A total of 20 patients who were radiologically suggestive of hydatid cyst but were diagnosed differently or unexpectedly diagnosed as hydatid cyst were included in the study. Lung cancer, bronchogenic cyst, or bronchiectasis were detected in 13 patients who were radiologically suggestive of hydatid cyst. There were 7 patients who were diagnosed with hydatid cysts, although they did not have specific radiological findings. Conclusions: While hydatid cysts can mimic many lung pathologies, many benign or malign parenchymal lung pathologies may exhibit hydatid cyst-like radiological features. Therefore, in regions where a hydatid cyst is endemic, the surgeon should consider all possibilities while managing the cases.
