[Lung carcinoma patients aged eighty years over and prognostic factors affecting survival]. / Seksen yas üzerindeki akciger kanseri olgulari ve sagkalimi etkileyen faktörler.

INTRODUCTION: Almost 50% of all cancers and 70% of cancer deaths occur in cases aged 65 years and more. Thus diagnosis, treatment and follow up in old cases gain importance. Since there a limited number of study that show age-mortality relation in lung cancer cases aged 80 years and over, issues may arise in diagnosis and treatment process of these cases. In this study, we aimed to evaluate general characteristics of lung cancer cases aged 80 years or over and factors that affect survey. MATERIALS AND METHODS: Between 2010 and 2013, the retrospective cohort study was done in Sureyyapasa Chest Diseases and Chest Surgery Training and Research Hospital and 100 cases of lung carcinoma were examined. RESULT: In the study, 70% of the cases were male and 30% were female. Median age was 83 ± 2.91 (80-92) years. 71% of the cases were found to be suffering from a comorbid disease; 29% did not have any comorbid disease. Dyspnea (56%), cough (50%) and chest pain (41%) were the most frequent symptoms. Histopathologically, 41% of the patients diagnosed with adenocarcinoma and 40% were diagnosed with squamous cell carcinoma. Median survival time was 2.73 months (%95 CI 0.96-4.49) and 1-year survival rate was 17%. Length of time of the cases with smoking history was found shorter than of cases without smoking history (p= 0.013). Life expectancy of the cases with advanced disease and performance score of 3-4 was detected to be short (p= 0.006, p< 0.001). Compared to the cases who operated on and had chemoradiotherapy, length of life who had symptomatic treatment was shorter (p< 0.001). CONCLUSIONS: Despite the comorbidity in lung cancer cases aged 80 years and over, life expectancy of the cases who had surgical and/or chemoradiotherapy treatment is longer. While deciding on treatment methods on these cases, patient's performance must be taken into consideration.

The sensitivity and specifity of DR-70 immunoassay as a tumor marker for non-small cell lung cancer.

INTRODUCTION: Lung cancer is the most important causes of the cancer related mortality. Patients with lung cancer are usually diagnosed at advanced or locally advanced stage, for this reason early diagnosis of lung cancer is very important. For early detection of lung cancer some methods are emphasized such as low-dose computed tomography or tumor biomarkers. In this study we aimed to evaluate DR-70 sensitivity and specificity as a tumor marker in detection of non-small cell lung cancers. PATIENTS AND METHODS: Between May 2013 and April 2014, the serum samples from 88 non lung cancer patients, 86 patients with chronic obstructive pulmonary disesase were obtained. Blood samples from each participant were analyzed for DR-70 level. RESULT: Totally 174 patients were enrolled to the study (152 male, 22 female). Histopathologically 47(53.4%) patients were diagnosed with squamous cell lung cancer, 34 (38.6%) with adenocarcinoma, and 7 (8%) with non-small cell lung cancer. The mean serum DR-70 levels in lung cancer patients (2.43 ± 1.82 µg/mL) was significantly higher compared to the 86 non-cancerous subjects (1.15 ± 0.70 µg/mL) (p< 0.01). DR-70 exhibited clinical sensitivity and specificity of 54.5 and 83.7%, respectively, at an optimal cut off at 1.98 µg/mL. It could be said that the risk of the presence of the disease is 6.171 times higher in the cases where DR-70 level is 1.98 µg/mL and higher. CONCLUSION: DR-70, a marker used to measure fibrin degradation products, generated by all major cancers, may helps to find high risk lung cancer patients.

Castleman's disease presenting as a pleural mass in the thoracic cavity.

A 61-year-old non-smoking Turkish woman presented with chest pain for 10 months. Computed tomography of the chest revealed a solitary, relatively well circumscribed, heterogeneous mass of 4 x 6 cm diameter in left posterior-lateral hemithorax. On thoracotomy, an extraparanchymal mass destructing the ribs was determined. Mass excision and partial chest wall resection were performed. On histopathologic examination, this mass showed features of the hyaline vascular type of Castleman's disease.
