[CT evaluation of response to chemotherapy and/or radiotherapy in primary lung cancer: comparison of response evaluation criteria in solid tumors (RECIST) and the WHO criteria, and comparison of both methods with the histological evaluation].

Purpose: The new RECIST criteria for evaluation of tumor response to chemotherapy and/or radiotherapy were proposed in 1999. We compared RECIST with the WHO criteria and also compared both methods with the histological findings, to evaluate RECIST.

Subjects And Methods: The subjects were 32 primary lung cancer patients operated on after chemotherapy and/or radiotherapy.

[Percutaneous localization of pulmonary nodules with CT guidance for lung resection: use of dyes].

Objective: The purpose of this study was to assess the benefits of computed tomography(CT)-guided marking using dyes in patients undergoing lung resection for peripheral nodules.

Methods: Between January 1997 and August 2002, the location of small pulmonary nodules was identified with the aid of CT-guided marking in 52 patients scheduled for surgery. Dye-injection was performed in 52 patients (indigo carmine, n = 15; indocyanine green, n = 37).
