Randomized Controlled Trial Multicenter Study
Phase II prospective study of the efficacy of gefitinib for the treatment of stage III/IV non-small cell lung cancer with EGFR mutations, irrespective of previous chemotherapy.
Mutations in the epidermal growth factor receptor (EGFR) gene are associated with increased sensitivity of non-small cell lung cancer (NSCLC) to gefitinib, an EGFR tyrosine kinase inhibitor. The objective of this study was to prospectively evaluate the efficacy of gefitinib in patients with stage III/IV NSCLC whose tumors carried EGFR mutations, irrespective of previous chemotherapy. ⋯ Analysis of tumor EGFR mutations in patients with NSCLC could be used to identify patients suitable for treatment with gefitinib to obtain optimum response and disease control rates.

To evaluate quality of life (QoL) evolution after thoracic surgery for lung cancer with the European Organisation for Research and Treatment of Cancer (EORTC) QoL Questionnaire-C30 and the lung cancer specific module LC13. ⋯ The present study documented QoL evolution profiles comparing pre-operative status with deficits and changes at 1, 3, 6 and 12 months after pulmonary surgery. Lung cancer surgery is well tolerated by the majority of patients. Lobectomy patients have a more favorable physical functioning and less thoracic pain, compared to pneumonectomy. Antero- and posterolateral thoracotomy are comparable for QoL evolution. After posterolateral thoracotomy more post-operative pain and dyspnea was seen. Post-operative physical functioning, pain and QoL are in favor of VATS.

This study reports the efficacy of adjuvant chemotherapy in stage IA non-small cell lung cancer (NSCLC) with vessel invasion (Vi). We sub-divided 322 patients with surgically resected pathological stage IA NSCLC into two groups according to Vi [non-Vi (n=237) and Vi (n=85)]. Both groups were compared with regard to age, gender, performance status, smoking habits, serum carcinoembryonic antigen level, extent of surgery, tumour size, histopathology, recurrence sites, and survival. ⋯ In conclusion, vessel invasion is a poor prognostic factor in patients with stage IA NSCLC. Prognosis of patients with Vi-stage IA NSCLC is similar to that of patients with stage IB NSCLC and is improved significantly by postoperative oral uracil-tegafur chemotherapy. Our preliminary study suggests that stage IA Vi group benefits from adjuvant chemotherapy.
