Efficacy and Safety Aiming at the Combined-Modality Therapy of External Beam Radiotherapy (40Gy) and Iodine-125 Seed Implantation for Locally Advanced NSCLC in the Elderly.

PURPOSE: To evaluate the efficacy and safety of combined-modality therapy for elderly patients with locally advanced non-small-cell lung cancer (NSCLC) invading the chest wall. PATIENTS AND METHODS: We retrospectively enrolled 21 elderly patients (aged ≥60 years) with locally advanced NSCLC invading the chest wall. For external beam radiotherapy (EBRT) of the primary tumor, 40Gy was applied and supplemented with iodine-125 seed implantation while 60Gy was applied to the lymph nodes of the mediastinum. Follow-up was conducted every 3 months postoperatively. The related analytic parameters were change in tumor size, the objective response rate (ORR), the disease control rate (DCR), the degree of pain relief, the improvement of physical status, and toxicity. RESULTS: The combined-modality therapy significantly inhibited local growth of the tumor (from 7.84±1.20 to 4.69±1.90 cm) (P <0.0001), with 71.4% ORR and 90.5% DCR at 1 year. The cancer-related pain was significantly relieved (P <0.05) and physical status was significantly improved (P <0.05). No procedure-associated death or grade > 2 irradiation-related adverse effects were reported in this study. CONCLUSION: The combined-modality therapy of EBRT with 40Gy and permanent iodine-125 seed implantation is an efficacious and safe treatment option for elderly patients with locally advanced NSCLC invading the chest wall.

A phase II study of preoperative chemotherapy with modified FOLFOX6 followed by surgery and postoperative chemoradiation in patients with localized gastric adenocarcinoma.

The optimal neoadjuvant and adjuvant treatment for gastric cancer remains controversial. We conducted a phase II study using preoperative chemotherapy with modified FOLFOX6 followed by surgical resection and postoperative chemoradiation in patients with gastric carcinoma. Preoperative chemotherapy (two or three cycles) consisted of a 2-h infusion of oxaliplatin (100 mg/m2) and folinic acid (100 mg/m2) followed by a 46-h continuous infusion of 5-fluorouracil (5-FU; 2,400 mg/m2). Surgical resection was planned 4 weeks after the last chemotherapy cycle. Patients underwent postsurgical chemoradiation, receiving a total dose of 45 Gy and 5-FU continuous infusion (350 mg/m2/day). The primary end points were feasibility, overall response rate, and R0 resectability rate after preoperative chemotherapy. The secondary end points were tolerability, treatment-associated complications, disease-free survival, and overall survival. Nineteen patients were enrolled in this study. After neoadjuvant treatment, four patients (21.1%) experienced progressive disease, six patients (31.6%) showed partial remission, and nine patients (47.3%) showed stable disease. In 15 patients (78.9%) R0 resectability could be achieved. Eleven of these patients (73.3%) were able to undergo postoperative chemoradiation. Notably, eight (72.7%) of these patients were disease free and alive at median follow-up of 60 months. Chemotherapy associated neutropenia, neutropenic fever, and anastomotic dehiscence were observed. The combination of preoperative chemotherapy and postoperative chemoradiation is feasible in a significant subset of gastric cancer patients.
