Induction chemoradiation compared with induction radiation for lung cancer involving the superior sulcus
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 survival. Induction chemoradiotherapy (CT/RT) has been shown to reduce local and distant recurrences and improve survival in stage III lung cancer. We investigated the role of induction CT/RT in superior sulcus patients.
Results. From 1985 to 2000, 35 consecutive patients underwent induction treatment followed by resection of a superior sulcus tumor. All patients had mediastinoscopy first to exclude N2 disease, and all were N0 at final pathologic examination. Twenty patients had induction RT (mean, 39 Gy), and 15 had induction CT/RT (mean, 51 Gy) with concurrent
Conclusions. Induction CT/RT for superior sulcus tumors appears to offer improved survival compared with induction RT alone.

Background. Membranes of tumor cells have been found to posses higher fluidity than membranes of nontumor cells. Plasma membrane fluidity is significantly correlated with malignant potential of

Background. Pulmonary blastomas are rare lung tumors that morphologically resemble fetal pulmonary structure and can exist in two forms, biphasic and monophasic. We reviewed our experience over

Background. Assessment of surgical risk in patients undergoing pulmonary resection is a fundamental goal for thoracic surgeons. Usually used risk indices do not predict the individual outcome.
