EGFR, ERBB2, and KRAS mutations in Korean non-small cell lung cancer patients.

The epidermal growth factor receptor (EGFR), and its family members play an important role in the development and progression of lung cancers. It has been reported that somatic mutations in the tyrosine kinase domain of the EGFR or ERBB2 genes occur in a subset of patients with lung cancer. We searched for mutations of the EGFR, ERBB2, and KRAS genes in surgically resected non-small cell lung cancers (NSCLCs) to determine the prevalence of these mutations in Korean lung cancer patients.

The Effects of Irradiation on Lung Function in Patients with Lung Cancer.

Purpose: This study was performed to assist in the prediction of the clinical tolerance of patients with lung cancer to irradiation.

Materials And Methods: The changes in lung function of 26 patients with lung carcinomas, who had received radiation with curative intent, or postoperative adjuvant radiotherapy, were prospectively studied. Their pulmonary function tests were conducted at presentation, and then at 2 weeks, 2 months, and 6 months, following radiotherapy.
