The possibility of using it to define subsets of patients with different prognosis in cancer could be of vital clinical importance. Materials and Methods: Fifty patients (5 women, 45 men; mean age, 64.47 years) with SCLC were retrospectively studied. Tumor specimens were stained for CD105, and intratumoral lymphatic microvessel density (ILMVD) and lymphatic invasion were determined. Results: Twenty-five patients were diagnosed with limited and 25 with extensive SCLC. All patients received chemotherapy and 32.7% radiation therapy. A direct association between ILMVD (CD105 expression) and lymphatic invasion was observed (p<0.046). CD105 expression was significantly associated with the stage of the disease (p=0.004) and the presence of metastasis (p=0.05). Conclusion: CD105 expression and lymphatic invasion correlated significantly with the clinical parameters and patient outcome, therefore, constituting an important prognostic role in SCLC.
