Survival analysis of rats implanted with porous titanium tracheal prosthesis
Background. Surgical treatment of a malignancy in the trachea may lead to a long resection that has to be reconstructed with an artificial prosthesis. However, most of the available prostheses encounter inflammatory rejection and mechanical constraint problems. To improve tracheal rehabilitation a porous titanium prosthesis was developed. The aim of this study was to test the biocompatibility of this novel material.
Results. Fibroblast colonization of titanium pores and a ciliary cylindrical epithelial layer developed on the endoluminal side of the prosthesis and the inflammatory reaction was minimal.
Conclusions. The results

Background. The usual approach of induction radiation therapy (RT) followed by resection of superior sulcus tumors results in many incomplete resections, a high local recurrence rate, and suboptimal

Background. Routine lung cancer screening does not currently exist in the United States. Computed tomography can detect small cancers and may well be the screening choice in the future. Controversy
