Abstract

Malignant pleural mesothelioma is a frequently fatal disease and the impact of available treatments is globally poor. Identification of new prognostic factors would help in the understanding of disease progression and, possibly, patient management. Here, we evaluate the prognostic impact of the neurotensin (NTS) and its cognate receptor (NTSR1) known for mediating cellular proliferation, survival, invasiveness, and mobility. We studied a series of 52 consecutive patients with epithelioid malignant mesothelioma undergoing management with curative intent, by immunohistochemistry for the expression of NTS and NTSR1. Specimens were scored as 0, 1, or 2 for less than 10%, between 10 and 50%, or more than 50% of NTS positive staining in tumor cells, respectively. Immunohistochemistry revealed that NTS and NTSR1 expression was found in 71.1% and 90.4% of malignant mesotheliomas, respectively. Using univariate analysis, expression of NTS was significantly (p = 0.015) related with a poor prognosis, with median survivals of 11.0 months, 18.4 months, and 29.8 months in patients showing expression scored as 2, 1, and 0, respectively. Multivariate analysis showed that expression of NTS (p = 0.007) and non-surgical therapy (p = 0.004) were i...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
