Survival outcomes of pneumonectomy with left atrial resection for non-small cell lung cancer.

Background: Lung cancer invading left atrium is accepted as T4 tumor and surgical treatment in this situation is controversial. The aim of our study was to determine the prognostic factors of patients with surgically treated non-small cell lung cancer (NSCLC) invading left atrium. Methods: After the approval of local ethics committee, the study was conducted in Gazi University, Department of Thoracic Surgery (Ankara-Turkey). The records of the patients were obtained from the encrypted hospital management software. Sequential codes were given to the data of patients and it was transferred to the statistics program without their names and ID numbers. The data of patients were collected as follows: those who had extended pneumonectomy from the surgery reports were found, then their pathology reports were examined, and those who had atrial muscle tissue were included in the study. Selected cases included as follows: patients who were medically suitable for surgery, patients who could tolerate surgery in cardiology evaluation, patients who had adequate lung capacity for pneumonectomy. Data of patients were analyzed according to age, gender, lymph node invasion, complete resection, and operative mortality. Results: A total of 18 patients were included in the study. There were 16 (88.8%) men and 2 (12.2%) women. The mean age was 60.8 (range: 44 -76; Standard deviation: ± 1.8) years. Cardiopulmonary bypass was used in only one patient. The 30-day mortality was 5.5%. 1, 3, and 5-years overall survivals were 77%, 18.6%, and 9.3%, respectively. Mediastinal lymph node metastasis in N1 and N2 stations was detected 10 and 2, respectively. There was statistically significant correlation between recurrence and lymph node invasion status including N1 and N2 station (P = 0.04). Conclusion: ">Although surgery is controversial in patients with NSCLC invading left atrium, it can be performed in selected cases. Morbidity and mortality rates were acceptable.

Metachronous Eosinophilic Granuloma of Rib in an Adult Patient.

Eosinophilic granuloma (EG) is the unifocal osseous form of Langerhans cell histiocytosis (LCH), which usually affects the skull and long bones. Although it most commonly affects the pediatric age group, it can rarely be seen in adults. Skeletal involvement is common in adult patients, but isolated rib involvement is extremely rare. Differential diagnosis includes other osteolytic lesions such as Ewing's sarcoma, tuberculosis, multiple myeloma, lymphoma, and primary bone malignancy. The diagnosis must be confirmed histopathologically. In addition to pathological Langerhans cells, inflammatory cells such as lymphocytes, eosinophils, and macrophages are observed in microscopy. Immunohistochemically, CD1a, S-100, and Langerin positivity are observed in biopsy and/or surgical excision material. Treatment options may vary depending on the localization and extent of the disease. In unifocal EG, close observation of the patient may be preferred, as well as surgical excision, radiotherapy, and intra-lesional steroid administration. The prognosis in patients with a single bone lesion is quite good compared to other groups. In this case report, we present a metachronous EG of rib developed in two different ribs by an interval of seven years, which were both surgically treated. In this mild variant of LCH, surgical resection with clean margins has a favorable outcome without the need for additional adjuvant therapy. Metachronous tumors may develop in isolated unifocal bone EGs, and long-term follow-up is mandatory.

Primary pulmonary adenoid cystic carcinoma: report of two cases.

A 51-year-old man with adenoid cystic carcinoma in the main stem bronchus was treated by a left lower lobectomy. A 44-year-old man with adenoid cystic carcinoma in the peripheral small bronchi underwent a right sleeve upper lobectomy with tracheobronchoplasty and neo-carina reconstruction; because of positive tumor margins, radiotherapy was administered postoperatively. Both patients were alive without any signs of tumor after 30 and 24 months of follow-up, respectively.

Endobronchial lipomatous hamartoma.

Pulmonary hamartomas are the most common benign neoplasm of the lung, occurring in the parenchyma or sometimes within the bronchi. Reported is a case of a 64-year-old male patient with an endobronchial tumor. Sleeve left upper lobectomy was performed and histopathological examination revealed multiple growths of endobronchial hamartomatous foci. This report demonstrates that endobronchial hamartomas may develop from multiple foci.

Surgical management of pulmonary aspergilloma.

Records of 59 patients (41 males and 18 females) who underwent 70 operations for pulmonary aspergilloma in a 23-year period were examined retrospectively. Sixty-three operations were for primary treatment of pulmonary aspergilloma, and 7 were for complications of surgery. Twenty-six postoperative complications occurred in 19 patients. Three lobectomies that resulted in bronchopleural fistula were managed by intercostal muscle-flap closure and partial thoracomyoplasty. Two patients died within the first week of surgery. Surgery is the treatment of choice for most patients with pulmonary aspergilloma. Selective bronchial artery embolization is helpful only in combating hemoptysis, and this has been considered a temporary measure in most reports. Thus, open thoracotomy and anatomical resection are recommended as early as possible after the diagnosis is established.
