Abstract

Pleomorphic carcinoma is a rare epithelial malignant tumor. Because the clinical characteristics and behavior of the disease remain unclear, we investigated the clinicopathological findings and prognosis of 60 patients with pleomorphic carcinoma. The clinicopathological characteristics of 60 cases of pulmonary pleomorphic carcinoma identified between 1999 and 2011 were studied. Of these, 55 patients had peripheral disease and five had central disease. The tumor size in all patients was 1-9.5 cm (mean, 5.8 ± 4.5 cm), while 30 had lesions with a diameter larger than 5 cm. All patients underwent pulmonary resection. There were no in-hospital deaths. The three and five year survival rates of all patients were 47.2% and 25.6%, respectively. The three and five year survival rates were 57.3% and 32.5% for N0 patients, and 25.4% and 17.1% for N1-2 patients, respectively. Overall survival was significantly different between the radical resection and incomplete resection groups. Multivariate Cox regression analyses of overall survival for all 60 patients indicated that radical resection (P= 0.041), tumor node metastasis (TNM) stage (P= 0.044), and nodal status (P= 0.029) were significant independent prognostic factors.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
