Background: Although early-stage lung cancer has increased owing to the introduction of screening programs, high recurrence rate remains a critical concern. We aimed to explore biomarkers related to the prognosis of surgically resected non-small-cell lung cancer (NSCLC). Methods: In this retrospective study, we collected medical records of patients with NSCLC and matched tissue microarray blocks from surgical specimens. Semiquantitative immunohistochemistry was performed for measuring the expression level of fibroblast activation protein-alpha (FAP-α), Jagged-1 (JAG1), and CUB-domain-containing protein 1 (CDCP1). Results: A total of 453 patients who underwent complete resection between January 2011 and February 2012 were enrolled; 55.2% patients had stage I NSCLC, and 31.1% presented squamous cell carcinoma. Disease stage was a significant risk factor for recurrence and death, and age ≥ 65 years and male sex were associated with poor overall survival. FAP-a and JaG1 were not related to survivals, while CDCP1-expressing patients exhibited poor disease-free and overall survival. Moreover, CDCP1 expression in stage I NSCLC was significantly associated with recurrence. Conclusions: Old age, male sex, and high pathological stage were poor prognostic factors in patients with NSCLC who underwent surgical resection. Furthermore, CDCP1 expression could serve as a biomarker for poor prognosis in stage I NSCLC.

Volume Changes

Abstract The purpose of the study was to investigate the association between tumor volume changes during stereotactic body radiation therapy (SBRT) and prognoses in stage I non-small-cell lung cancer (NSCLC). This retrospective review included stage I NSCLC patients in whom SBRT was performed at a total dose of 48.0–50.5 Gy in four or five fractions. The tumor volumes observed on computed tomography (CT) simulation and on the CT performed at the last treatment session using a CT-on-rails system were measured and compared. Then, the tumor volume changes during the SBRT period were measured and assessed for their association with prognoses (overall survival, local control, lymph node metastases and distant metastases). A total of 98 patients with a mean age of 78.6 years were enrolled in the study. The T-stage was T1a in 42%, T1b in 32% and T2a in 26% of the cases. The gross tumor volume (GTV) shrank and increased ≥10% in 23 (23.5%) and 36 (36.7%) of the cases, respectively. The 5-year local control and overall survival rates in the groups with a tumor shrinkage of ≥10% vs the group with a shrinkage of <10% were 94.7 vs 70.8% and 85.4 vs 47.6%, respectively; these differences were significant, with a P-value < 0.05. During a short SBRT period, the tumor shrank or enlarged in a small number of cases. A decrease of ≥10% in the GTV during SBRT was significantly related to better overall survival and local control.

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.

Subset Analysis

e21109 Background: Historically, limited stage Small Cell Lung Cancer (SCLC) has been treated with concurrent chemoradiation (CRT). While current NCCN guidelines recommend consideration of lobectomy in node-negative cT1-T2 SCLC, real world data regarding the role of surgery in very limited SCLC is lacking. To our knowledge, only one retrospective study has evaluated the role of surgery in stage I SCLC. Methods: Data from the National VA Cancer Cube were compiled. A total of 1,028 patients with pathologically confirmed Stage I SCLC were studied. Only 661 patients that either received surgery or CRT were included. Interval-censored Weibull and Cox proportional hazard regression models were used to estimate median overall survival (OS) and hazard ratio (HR), respectively. Two survival curves were compared by a Wald test. Subset analysis was performed based on the location of the tumor in the upper vs lower lobe as delineated by ICD-10 codes C34.1 and C34.3. Results: Four-hundred and forty-two patients received concurrent CRT; while 219 underwent treatment that contained surgery (92 surgery only, 84 surgery/chemo, 39 surgery/chemo/radiation and 4 surgery/radiation). The median OS for the surgery-inclusive treatment was 3.87 years (95% CI 3.25-4.60) while median OS for the CRT cohort was 2.43 years (95% CI 2.15-2.72). HR of death for surgery-inclusive treatment when compared to CRT was 0.65 (95% CI 0.54-0.79; p < 0.001). Subset analysis based on the location of the tumor in upper lobe and lower lobe showed improved survival with surgery as compared to CRT regardless of the location. HR for upper lobe was 0.61 (95% CI 0.48-0.78; p < 0.001) and lower lobe 0.60 (95% CI 0.41-0.87; p = 0.007). Multivariable regression analysis accounting for age and ECOG-PS shows a HR 0.60 (95% CI 0.42-0.85; p = 0.004) favoring surgery. Conclusions: Surgery was used in less than a third of patients with stage I SCLC who received treatment. Surgery-inclusive multimodality treatment was associated with a longer overall survival as compared to chemoradiation, independent of age, performance status or tumor location. Our study supports a more expansive role for surgery in stage I SCLC.

Background According to practice guidelines, patients with clinical stage T1–2 node-negative small-cell lung cancer are candidates for surgical resection. However, the role of pneumonectomy in small-cell lung cancer patients is not well understood. The objective of this study was to assess the extent to which pneumonectomy is used and to evaluate the survival implications for small-cell lung cancer patients who underwent pneumonectomy. Methods A total of 106 small-cell lung cancer patients who underwent pneumonectomy between 2006 and 2016 and met the study criteria were identified in the National Cancer Database. Demographics and treatment regimens are described, and overall survival was assessed using Kaplan-Meier and log-rank tests. Results The most common treatment was surgery with adjuvant chemotherapy, followed by surgery only and surgery with neoadjuvant therapy. The 5-year overall survival for the entire cohort after pneumonectomy was 23%. In subgroup analysis, the 5-year overall survival was 30% for guideline-concordant clinical stage I patients and 28% for clinical stage II/III patients who underwent pneumonectomy. There was no statistical difference in survival according to pathologic N disease. Patients with a right-sided pneumonectomy had higher mortality than patients with a left-sided pneumonectomy. Conclusions This study suggests a role for pneumonectomy in clinical stage I and potentially some clinical stage II and III small-cell lung cancer patients. Right-sided pneumonectomy is associated with higher mortality and should be approached with caution. Despite declining trends over the past decades, pneumonectomy is still an effective treatment that is able to achieve acceptable survival outcomes.

Abstract Background Interstitial lung abnormalities (ILA) can be detected on computed tomography (CT) in lung cancer patients and have an association with mortality in advanced non-small cell lung cancer (NSCLC) patients. The aim of this study is to demonstrate the significance of ILA for mortality in patients with stage I NSCLC using Boston Lung Cancer Study cohort. Methods Two hundred and thirty-one patients with stage I NSCLC from 2000 to 2011 were investigated in this retrospective study (median age, 69 years; 93 males, 138 females). ILA was scored on baseline CT scans prior to treatment using a 3-point scale (0 = no evidence of ILA, 1 = equivocal for ILA, 2 = ILA) by a sequential reading method. ILA score 2 was considered the presence of ILA. The difference of overall survival (OS) for patients with different ILA scores were tested via log-rank test and multivariate Cox proportional hazards models were used to estimate hazard ratios (HRs) including ILA score, age, sex, smoking status, and treatment as the confounding variables. Results ILA was present in 22 out of 231 patients (9.5%) with stage I NSCLC. The presence of ILA was associated with shorter OS (patients with ILA score 2, median 3.85 years [95% confidence interval (CI): 3.36 – not reached (NR)]; patients with ILA score 0 or 1, median 10.16 years [95%CI: 8.65 - NR]; P <  0.0001). In a Cox proportional hazards model, the presence of ILA remained significant for increased risk for death (HR = 2.88, P = 0.005) after adjusting for age, sex, smoking and treatment. Conclusions ILA was detected on CT in 9.5% of patients with stage I NSCLC. The presence of ILA was significantly associated with a shorter OS and could be an imaging marker of shorter survival in stage I NSCLC.
