Abstract Purpose: Anemia has been associated with poor prognosis in patients with cancer across several cancer types. It has been identified as a prognostic factor in patients with non-small cell lung cancer (NSCLC) who have undergone surgery or chemoradiotherapy. However, there are only a few reports that have evaluated the prognostic significance of anemia in patients with NSCLC undergoing stereotactic body radiation therapy (SBRT). Material and Methods: A total of 77 patients were enrolled this study. The pretreatment hemoglobin (Hb) levels, within 2 weeks before SBRT, were available for all patients. The median age of the participants (56 men, 21 women) was 80 (range, 50-90) years. The median Hb level was 12.8 (range, 7.8-18.3) g/dL. The median follow-up period was 24 (range, 1-87) months. Results: Local recurrence was observed in 8 (10.4%) cases during the follow-up period. The 1- and 2-year local control (LC) rates were 94.8 and 86.4%, respectively. Seventeen (22.1%) patients died during the follow-up period. The 1- and 2-year overall survival (OS) rates were 93.1 and 85.2%, respectively. Univariate analysis identified anemia and body mass index as significant prognostic factors for predicting OS. On multivariate analysis, anemia was confirmed to be the only significant factor (p = 0.02469). Conclusion: Our data suggest that anemia is a prognostic factor for predicting the OS rate in patients with early-stage NSCLC treated with SBRT.

Background. The aim was to investigate the potential factors related with overall survival of oligometastatic non-small-cell lung cancer (NSCLC) patients. Methods. A literature search was conducted in databases including PubMed, Embase, and Cochrane library up to March 2017. The hazard radio (HR) as well as the corresponding 95% confidence interval (CI) were calculated, and all the statistics analysis was performed by the R 3.12. Heterogeneity was analyzed using I-squared and Cochran Q tests. Furthermore, sensitivity analysis was performed to evaluate the stability of results. Results. In total, 6 articles were included in the meta-analysis. Nodal status was significantly correlated with the overall survival rate of NSCLC oligometastatic patients (HR: 1.69, 95% CI: 1.23–2.32, Z=3.20, P=0.001). No significant relationship was found between overall survival rate of NSCLC oligometastatic patients and the indicators including sex, stage, smoker, age, and histology. Notably, sensitivity analysis on data evaluating relationship between patients survival and the stage and histology showed that results were reversed after removing one of the studies. Conclusions. Nodal status might be associated with the overall survival of oligometastatic NSCLC patients.

Radical Treatment

7623 Background: Stereotactic radiotherapy (SRT) has been aggressively performed as a radical treatment for stage I non-small cell lung cancer (NSCLC) in Japan, however most cases were medically inoperable. In a large Japanese multi-institutional experience, we reviewed the treatment outcome of SRT for medically operable stage I NSCLC cases with the patients’ refusal to surgery. Methods: In 1995–2004, 86 medically operable patients with stage I NSCLC (median age, 74 years; 62 T1N0M0; 24 T2N0M0) were treated with SRT alone in 14 reliable institutions. Stereotactic three-dimensional treatment was performed using non-coplanar dynamic arcs or multiple static ports. A total dose of 20 to 72.5 Gy at the isocenter was administered in 1 to 10 fractions. Median calculated biological effective dose (BED) was 115 Gy (range, 100–153 Gy). The data was collected and analyzed in a retrospective manner. Results: During follow-up (median, 43 months), pulmonary complications of above grade 2 arose in 4 patients (5.8%). Local control rates at 3 and 5-year post SRT were 88.1% and 85.5%, respectively. Three and 5-year overall survival rates were 80.7% and 71.3%, respectively. Five-year overall survival rate for patients whose age was over 70 years (n=27) and under 70 years (n=58) were 74.3% and 69.6%, respectively. Five-year overall survival rate for stage IA (n=62) and IB (n=24) cases were 72.3% and 68.4%, respectively. Conclusions: SRT is safe and promising as a radical treatment for operable stage I NSCLC. The survival rate of SRT is potentially comparable to that of surgery. No significant financial relationships to disclose.
