1. PURPOSE: We investigated the role of computed tomography (CT)-guided Iodine-125 (125I) seed implantation in combination with chemotherapy for the treatment of stage III non-small cell lung carcinoma (NSCLC). Pubmed PURPOSE: We investigated the role of computed tomography (CT)-guided Iodine-125 (125I) seed implantation in combination with chemotherapy for the treatment of stage III non-small cell lung carcinoma (NSCLC). MATERIAL AND METHODS: The data from 182 patients with stage III NSCLC who were treated with radioactive 125I seed implantation between June 2002 and June 2009, and who received sequential platinum-based combination chemotherapy using the most common combination of platinum and gemcitabine, were retrospectively reviewed. The 182 patients received a prescribed dose of 110.0 Gy, with a median radioactivity of 0.70 mCi (range, 0.64-0.78 mCi, 2.37-3.26 × 107 Bq). The median number of 125I seeds was 38 pellets (range, 6-105 pellets). The median post-operation dose covering 100% of the target volume (D100) was 94.5 Gy (range, 54.6-125.5 Gy). The median D90 was 143.0 Gy (range, 121.6-184.0). RESULTS: The 1-, 3-, and 5-year overall survival rates were 83.35%, 25.57%, and 11.34%, respectively; the median survival time was 24.76 months. At 1, 3, and 5 years, the local control rates were 92.01%, 86.51%, and 76.45%, respectively; the median local control time was 25.28 months. For patients with stage IIIA and IIIB NSCLC, the median survival times were 26.67 and 24.59 months, respectively (p = 0.2). Pre-treatment hemoglobin level, tumor volume, and postoperative D100 were significantly associated with survival. A total of 24 patients experienced pneumothorax (incidence rate, 13.20%), and 17 patients experienced hemothorax (incidence rate, 5.0%). CONCLUSIONS: CT-guided 125I seed implantation combined with chemotherapy is an effective, minimally invasive method for the treatment of stage III NSCLC. Furthermore, hemoglobin levels before treatment, D100, and the maximum diameter of the tumor may be prognostic factors in patients with NSCLC treated sequentially with radiotherapy and chemotherapy. 125I; lung cancer; non-small cell lung carcinoma (NSCLC)
2. BACKGROUND: Little is known about the clinicopathological features and prognosis in elderly gastric cancer (GC) patients aged 65-79 years. Pubmed BACKGROUND: Little is known about the clinicopathological features and prognosis in elderly gastric cancer (GC) patients aged 65-79 years. The aim of this study was to evaluate clinicopathological features and prognosis in elderly GC patients. PATIENTS AND METHODS: From May 2008 to December 2014, a total of 5,282 GC patients were enrolled in our present study. Patients were divided into elderly and middle-aged groups. The clinicopathological features and clinical outcomes were analyzed. RESULTS: The proportion of dysphagia was significantly higher in elderly patients than that in middle-aged patients (P=0.002), whereas the proportion of abdominal pain and heartburn was significantly lower in elderly patients than that in middle-aged patients (P<0.001 vs P=0.038, respectively). The proportion of patients with carbohydrate antigen (CA) 19-9 was significantly higher in elderly patients than that in middle-aged patients (P=0.009). There was no significant difference in clinicopathological features between elderly and middle-aged patients with D2 gastrectomy (all P>0.05). Age, tumor size, histological type, tumor depth, lymph node metastasis, carcinoembryonic antigen, alpha fetoprotein, CA19-9, and CA125 were independent risk factors for the prognosis of GC patients in univariate and multivariate analyses. Overall survival in elderly patients was significantly reduced compared with middle-aged patients (P=0.001), especially in patients with tumor size >5 cm (P=0.002), poorly differentiated tumor (P<0.000), stage III tumor (P=0.002), or normal levels of carcinoembryonic antigen (P=0.009), alpha fetoprotein (P=0.002), CA19-9 (P=0.002), and CA125 (P=0.004). CONCLUSION: The clinicopathological features of elderly patients were different to those of middle-aged patients. The prognosis for elderly GC patients was significantly worse than for middle-aged patients. clinicopathological features; elderly; gastric cancer; prognosis
