Abstract OBJECTIVES Patients with oligometastatic non-small-cell lung cancer (NSCLC) may benefit from therapy with curative intent. Our goal was to identify prognostic factors related to better prognosis in a multicentre analysis of patients who underwent surgery of primary tumours in combination with radical treatment of all metastatic sites. METHODS We retrospectively reviewed the records of oligometastatic patients who underwent resection of primary tumours at 4 centres (August 2001–February 2018). Oligometastasis was defined as ≤5 synchronous metastases in ≤2 organs. Radical metastatic treatment was surgery, radiotherapy or a combination. The Cox proportional hazards model was used for identification of prognostic factors on overall survival. RESULTS We treated 124 patients; 72 (58%) were men, mean age 60 ± 9.8 years, with 87 (70%) adenocarcinoma. Sixty-seven (54%) patients had positive pathologic-N stage (pN). Brain metastases were most common (n = 76; 61%) followed by adrenal (n = 13; 10%) and bone (n = 12; 10%). Systemic therapy was administered in 101 (82%) patients. Median follow-up was 60 months [95% confidence interval (CI) 41–86]. Thirty- and 90-day mortality rates were 0 and 2.4%, respectively. One-, 2-, and 5-year overall survival were 80%, 58% and 36%, respectively. Cox regression analysis showed that patients ≤60 years [hazard ratio (HR) 0.41, 95% CI 0.24, 0.69; P = 0.001] and patients with pN0 (HR 0.38, 95% CI 0.21–0.69; P = 0.002) had a significant survival benefit. The presence of bone metastases negatively affected survival (HR 2.53, 95% CI 1.05–6.09; P = 0.04). CONCLUSIONS Treatment with curative intent of selected oligometastatic NSCLC, including resection of the primary tumour, can be performed safely and with excellent 5-year survival rates, especially in younger patients with pN0 disease.

18211 Background: Prognostic factors identified in advanced non small cell lung cancer are: age, gender, PS, h. SWOG univariable analysis in patients with chemotheraphy; confirmed these factors and show a relationship between the hemoglobin level and the overall survival; in addition the metastasic site number and cisplatin- based chemotheraphy (7). To analyse and compare the hemoglobin level before cisplatin- based chemotheraphy with survival in patients with advanced non- small cell lung cancer. Methods: Retrospective study conducted at the IONC of the 179 clinical record were analized, over a 5 year period. The collected data were: age, gender, PS, histologic type, stage, chemotheraphy cycles number, smooke history, number and metastasic site. We analyzed median and overal survival using Kaplan Meier, and the anemia as a prognostic implication factor with univariable and multivariable Cox regression analysis. Istologic type and TNM (1–6). Results: The mean age was 59 (40–79); 146 (81.5%) male and 33 (18.5%) women; histological types found were squamous cell carcinomas in 66 (37%), and adenocarcinoma in 113 (63%); stage IIIB in 61 (34%) and IV in 118 (66%). 147 (82%) were smokers and 32 (18%) were never smokers. All the patients had PS 0–1. Median overall survival time was 11.53 months and 13.88 months in the haemoglobin level < or > 11 gr/ 100 ml, respectively. (p=0.3). In univariable Cox regression analysis, smoking rates and chemotheraphy cycles number were predictors of survival (p=0.05 y p=0.018, respectively). Hemoglobine (p=0.55). In multivariable Cox regression analysis, only the number of cycles was predictor of survival (p=0.026). Hemoglobine (p=0.34). Conclusions: In our experience, a greater survival tendency was observed in patients with advanced non- small cell lung cancer who presented levels of Hemoglobine greater than 11 gr/dl, previous to cisplatin- based chemotherapy without statistical significance.

Abstract Background Lung cancer is one of the dominant causes of cancer-related deaths worldwide. Ferroptosis, an iron-dependent form of programmed cell death, plays a key role in cancer immunotherapy. However, the role of immunity- and ferroptosis-related gene signatures in non-small cell lung cancer (NSCLC) remain unclear. Methods RNA-seq data and clinical information pertaining to NSCLC were collected from The Cancer Genome Atlas dataset. Univariate and multivariate Cox regression analyses were performed to identify ferroptosis-related genes. A receiver operating characteristic (ROC) model was established for sensitivity and specificity evaluation. Gene ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses were performed to explore the function roles of differentially expressed genes. Results A signature composed of five ferroptosis-related genes was established to stratify patients into high- and low-risk subgroups. In comparison with patients in the low-risk group, those in the high-risk one showed significantly poor overall survival in the training and validation cohorts (P < 0.05). Multivariate Cox regression analysis indicated risk score to be an independent predictor of overall survival (P < 0.01). Further, the 1-, 2-, and 3-year ROCs were 0.623 vs. 0.792 vs. 0.635, 0.644 vs. 0.792 vs. 0.634, and 0.631 vs. 0.641 vs. 0.666 in one training and two validation cohorts, respectively. Functional analysis revealed that immune-related pathways were enriched and associated with abnormal activation of immune cells. Conclusions We identified five immunity- and ferroptosis-related genes that may be involved in NSCLC progression and prognosis. Targeting ferroptosis-related genes seems to be an alternative to clinical therapy for NSCLC.

Abstract Background leptomeningeal metastasis (LM) is a devastating scenario in patients with non-small cell lung cancer (NSCLC), with an estimated median overall survival (OS) of 4–6 months from diagnosis. Several studies have clarified the prognosis of treatment modalities after LM. However, just a few studies have clarified the prognosis of LM patterns. We evaluate the prognosis based on various patterns of LM under multidisciplinary treatment (MDT). Method This retrospective study evaluated NSCLC patients treated at National Taiwan University Hospital between 2007–2019 with brain metastases (BM) and LM. LM was classified into LM only, LM concurrent with BM, and LM after BM. Treatments including systemic therapy, whole-brain radiotherapy (WBRT), stereotactic radiosurgery (SRS), and intrathecal chemotherapy with Methotrexate (IT MTX) were recorded. BM excision was done by a neurosurgeon using minimally invasive neurosurgery. The MDT was done according to patients’ clinical situations. Kaplan-Meier methodology was used to describe overall survival OS. Multivariate Cox regression model was used to access prognostic factors. Result One hunderd patients with NSCLC CNS metastasis was included in this study. Median OS in patients with single, oligo and multiple BM was 42.0 months (95% CI= 0.12–83.89), 58.1 months (95% CI= 13.00–103.26), and 21.3 months (95% CI= 16.93–25.73), respectively. The median OS of all LM patients was 9.8 months. The median OS of LM after BM, concurrent BMLM, and LM only was 8 months (95% CI= 2.58–13.56), 41.5 months (95% CI= 0.00–94.36), and 18.5 months (95% CI=3.68–33.32), respectively. Multivariate Cox regression analysis showed only IT MTX (p= 0.010, HR= 0.392, 95%CI= 0.19–0.80) was associated with survival. Conclusion MDT in the TKI era has led to a dramatic improvement of OS in patients with LM (4–6 months vs. 9.8 months). NSCLC patients with LM only and concurrent BM LM has a better prognosis and longer survival, and thus are worth receiving intensive MDT care.

Abstract Aim: Centrally located early-stage non-small cell lung cancer in patients who are unfit for surgery are treated with fractionated radiotherapy. We present the outcomes of a moderately hypofractionated accelerated dose regimen of 50 Gy in 15 fractions from a single centre in the UK. Materials and methods: Electronic case notes and radiotherapy records of lung cancer patients treated between January 2014 and December 2016 were retrospectively reviewed. Adult Comorbidity Evaluation-27 score was used to evaluate comorbidities. Mean lung doses and percentage of lung receiving more than 20 Gy were calculated for all patients. Survival outcomes were estimated using Kaplan–Meier curves. Results: Fifty-three patients were included in the study; the median follow-up was 20.2 months. 87% of patients had stage I disease. There was no 30-day post-treatment mortality. Ninety-day mortality rate after radiotherapy was 3.8%. Grade 2 pneumonitis was seen in five patients while no grade 3 or 4 pneumonitis was observed. The median progression-free survival (PFS) and overall survival (OS) were 18.5 months and 28.2 months, respectively. The estimated 1 and 2 years PFS were 62.3% and 41.3%, respectively, and OS were 77.4% and 56.6%, respectively. Worsening performance status was associated with worse survival on cox regression analysis. Disease relapsed in 36% of patients. 7.5% of patients with relapsed disease had infield recurrence. Findings: 50 Gy in 15 fractions radiotherapy for central early-stage lung cancer is a feasible choice that requires further randomised trials.

Background: This study aims to identify the prognostic factors in Stage IIIA non-small cell lung cancer and to investigate whether there was a significant difference in terms of overall survival and disease-free survival among the subgroups belonging to this disease stage. Methods: Between January 2010 and December 2018, a total of 144 patients (125 males, 19 females; median age 60 years; range, 41 to 80 years) who were operated for non-small cell lung cancer in our clinic and whose pathological stage was reported as IIIA were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, histopathological diagnosis, the standardized uptake value of the mass on positron emission tomography-computed tomography, tumor diameter, type of surgery, lymph node metastasis status, visceral pleural invasion, and overall and disease-free survival rates were recorded. Results: The median survival was 39 (range, 27.8 to 46.1) months and the five-year overall survival rate was 28%. The mean tumor diameter was 4.3±2.7 cm. The median disease-free survival was 37 (range, 28.1 to 48.6) months and the five-year disease-free survival rate was 26.9%. In the multivariate analysis, overall survival and disease-free survival in T2N2M0 subgroup were significantly worse than the other subgroups. The other poor prognostic factors of survival were the standardized uptake value of the tumor, pneumonectomy, and histopathological subtypes other than squamous cell carcinoma and adenocarcinoma. Parietal pleural invasion was significantly associated with worse disease-free survival rates. Conclusion: Our results showed that there may be significant survival differences between subgroups created by tumor histopathology, lymph node invasion and the type of surgery in a heterogeneous lung cancer stage.

PURPOSE This study attempted to determine the prognostic value for survival of various pretreatment characteristics in patients with nonresectable non-small-cell lung cancer in the context of more than 10 years of experience of a European Cooperative Group. PATIENTS AND METHODS We included in the analysis all eligible patients (N = 1,052) with advanced non-small-cell lung cancer registered onto one of seven trials conducted by the European Lung Cancer Working Party (ELCWP) during one decade. The patients were treated by chemotherapy regimens based on platinum derivatives. We prospectively collected 23 variables and analyzed them by univariate and multivariate methods. RESULTS The global estimated median survival time was 29 weeks, with a 95% confidence interval of 27 to 30 weeks. After univariate analysis, we applied two multivariate statistical techniques. In a Cox regression model, the selected explanatory variables were disease extent, Karnofsky performance status, WBC and neutrophil counts, metastatic involvement of skin, serum calcium level, age, and sex. These results were confirmed by application of recursive partitioning and amalgamation algorithms (RECPAM), which led to classification of the patients into four homogeneous subgroups. CONCLUSION We confirmed by our analysis the role of well-known independent prognostic factors for survival, but also identified the effect of the neutrophil count, rarely studied, with the use of two methods: a classical Cox regression model and a RECPAM analysis. The classification of patients into the four subgroups we obtained needs to be validated in other series.
