BackgroundBrain metastasis (BM) is one of the most common failure patterns of pIIIA-N2 non-small cell lung cancer (NSCLC) after complete resection. Prophylactic cranial irradiation (PCI) can improve intracranial control but not overall survival. Thus, it is particularly important to identify the risk factors that are associated with BM and subsequently provide instructions for selecting patients who will optimally benefit from PCI.Methods and MaterialsBetween 2011 and 2014, patients with pIIIA-N2 NSCLC who underwent complete resection in our institution were reviewed and enrolled in the study. Clinical characteristics, pathological parameters, treatment mode, BM time, and overall survival were analyzed. A nomogram was built based on the corresponding parameters by Fine and Gray’s competing risk analysis to predict the 1-, 3-, and 5-year probabilities of BM. Receiver operating characteristic curves and calibration curves were chosen for validation. A statistically significant difference was set as P <0.05.ResultsA total of 517 patients were enrolled in our retrospective study. The median follow-up time for surviving patients was 53.2 months (range, 0.50–123.17 months). The median age was 57 (range, 25–80) years. Of the 517 patients, 122 (23.6%) had squamous cell carcinoma, 391 (75.6%) received adjuvant chemotherapy, and 144 (27.3%) received post-operative radiotherapy. The 1-, 3-, and 5-year survival rates were 94.0, 72.9, and 66.0%, respectively. The 1-, 3-, and 5-year BM rates were 5.4, 15.7, and 22.2%, respectively. According to the univariate analysis, female, non-smokers, patients with non-squamous cell carcinoma, bronchial invasion, perineural invasion, and patients who received adjuvant chemotherapy were more likely to develop BM. In a multivariate analysis, non-squamous cell carcinoma (subdistribution hazard ratios, SHR: 3.968; 95% confidence interval, CI: 1.743–9.040; P = 0.0010), bronchial invasion (SHR: 2.039, 95% CI: 1.325–3.139; P = 0.0012), perineural invasion (SHR: 2.514, 95% CI: 1.058–5.976; P = 0.0370), and adjuvant chemotherapy (SHR: 2.821, 95% CI: 1.424–5.589; P = 0.0030) were independent risk factors for BM. A nomogram model was established based on the final multivariable analysis result. The area under the curve was 0.767 (95% CI, 0.758–0.777).ConclusionsFor patients with IIIA-N2 NSCLC after complete resection, a nomogram was established based on clinicopathological factors and treatment patterns for predicting the BM. Based on this nomogram, patients with a high risk of BM who may benefit from PCI can be screened.

Background and Aim. The relative frequency of histological subtypes of lung cancer in Europe has changed dramatically during the 20th century. The aim of this study was to explore the changing epidemiology of lung cancer in Northern Greece over the last two decades. Methods. From the extensive database of the Bronchoscopy Unit of the G. Papanicolaou General Hospital, Thessaloniki, Greece, we identified all patients with a histologic and/or cytologic report positive for lung cancer over two consecutive decades. Results. Between 1/1/1986 and 31/12/2005 we identified 9981 patients with specimens positive for lung cancer. A significant increase in mean patient age was observed during the second decade (64.8±9.4 vs. 62.1±8.9, p=0.001). Men developed lung cancer ten times more often than women. The predominant histological type was squamous cell cancer in males (4203 cases, 45.7%) and adenocarcinoma (418 cases, 52.6%) in females. The number of lung cancer cases was significantly higher during the second decade compared to the first decade (5766 cases [57.8%] vs. 4215 cases [42.2%], respectively, p<0.001). There was a significant decrease in the percentage of squamous cell carcinoma in males in the second decade (2317 cases [44.1%] vs. 1886 cases [48.0%], p<0.001), and an increase in adenocarcinoma (1021 cases [19.4%] vs. 609 [11.6%], p<0.001). In females, the relative incidence of adenocarcinoma was decreased and that of squamous cell carcinoma was increased, but not significantly. There was no obvious change in the incidence of small cell lung cancer. Neoplastic lesions were most often located in the upper lobes. Conclusion. The number of lung cancer cases has increased in the last decade. Squamous lung cancer appears to be decreasing in men and increasing in women. Adenocarcinoma appears to be increasing in men and decreasing in women. There appears to be no change in small cell lung cancer. During the second decade there has been a significant decrease in the male: female ratio.

Background: The introduction of new therapies has made it important to differentiate between adenocarcinoma and squamous cell carcinoma. To allow the use of various immunocytochemical stains on limited materials, we tried transferring cells from a given smear to multiple slides. Using touch-preparation samples of 215 surgically resected non-small cell lung carcinomas of confirmed histologic classification (adenocarcinoma,n = 101; squamous cell carcinoma,n = 114), we performed immunocytochemistry for thyroid transcription factor-1, napsin A, p40, p63, CK5/6 and desmocollin-3, and compared cytologic staining results with the corresponding resection. Methods: We examined: (a) the expressions of the above 6 antibodies on cells transferred from touch imprints of resected specimens, the extent of staining being considered positive if more than 5% of the area was stained, and (b) the sensitivity, specificity, positive predictive value and negative predictive value for each antibody. Results: The histologic corresponding rate with Papanicolaou staining was only 73%. Regarding the differentiation of adenocarcinoma from squamous cell carcinoma, the sensitivity and specificity for napsin A in adenocarcinoma were 80 and 97%, respectively, while those for p40 in squamous cell carcinoma were 84 and 98%, respectively. Conclusion: The immunocytochemical expressions of napsin A and p40 in imprint cytology seem to be of great utility for the accurate histological differentiation of lung cancers.

T Cell Therapy

BackgroundGEN-011 is a personalized neoantigen-targeted peripheral blood T cell therapy (NPT) developed for the treatment of adult patients (pts) with solid tumors. The proprietary ATLAS™ (Antigen Lead Acquisition System) will be used to identify true immunogenic neoantigens from each patient‘s tumor mutanome that are recognized by their own CD4+ and/or CD8+ T cells. ATLAS will also identify Inhibigens™, antigen targets of T cells that promote tumor growth.1 Autologous peripheral T cells will be specifically stimulated by up to 30 ATLAS-identified neoantigens, avoiding Inhibigens, to generate an adoptive T cell product. Preliminary data show yields of billions of highly active T cells with 96% neoantigen targeting across 89% of ATLAS selected neoantigens.MethodsTITAN-1 is a multicenter Phase 1 study of GEN-011 NPTs in patients with refractory melanoma, non-small cell lung cancer (NSCLC), squamous cell carcinoma of the head and neck (SCCHN), urothelial carcinoma (UC), renal cell carcinoma (RCC), small cell lung cancer (SCLC), cutaneous squamous cell carcinoma (CSCC), and anal squamous cell carcinoma (ASCC). Patients may enter into one of 2 cohorts of 6 DLT-evaluable patients, either a multiple lower dose (MLD) regimen of GEN-011 as an IV infusion at 4-week intervals, up to 5 doses maximum without lymphodepletion, or a single high dose (SHD) regimen of GEN-011 after flu/cy lymphodepletion. Each dose of GEN-011 will be followed by a course of interleukin-2 (IL-2). Patients will be followed for safety, immunogenicity, and anti-tumor activity over approximately a 5-month treatment period. A long-term follow-up will continue through 2 years after the initial dose of GEN-011.Trial Registration clinicaltrials.gov identifier: NCT04596033ReferencesLam H, et al. An empirical antigen selection method identifies neoantigens that either elicit broad anti-tumor response or drive tumor growth.

Background/Aim. Lung cancer is one of the most common malignant tumors. About 80% of all lung cancers are non-small cell lung cancer (NSCLC). According to histopathological characteristics, the most common types of NSCLC are squamous cell carcinoma and adenocarcinoma. The aim of this study was to evaluate the overall survival rate in the NSCLC patients initially received surgery according to its histopathological type and T ? primary tumor, N ?regional lymph nodes, M ? distant metastasis (TNM) stages which were treated with surgical treatment, and after that, according to the TNM stage, chemotherapy protocols and/or radiation therapy. Methods. This retrospective case series study included all patients with NSCLC admitted to the Military Medical Academy in Belgrade in the period 2010?2015. A total number of selected patients was 85 (27 females and 58 males). Results. Out of 41 patients with squamous cell carcinoma, 19.5% deceased. On the other hand, in the group of patients with adenocarcinoma, 43.2% out of 44 patients deceased. The average cumulative survival was statistically significantly lower in the adenocarcinoma patients in comparison to the patients with squamous cell carcinoma (1,605.2 vs.1,304.8 days; p = 0.005). On the other hand, the average cumulative survival was statistically significantly lower in our patients in the recurrence group with adenocarcinoma in comparison to the recurrence group with squamous cell carcinoma (1,212.8 vs. 1,835.5 days; p = 0.032). Conclusion. Adenocarcinoma is more aggressive cancer in comparing to squamous cell carcinoma with lower overall survival in comparing to squamous cell carcinoma. Additional studies are needed to identify risk factors for recurrence after surgery, and to additionally explain role of tumor markers and molecular biological techniques in the progression of this kind of cancer.

Abstract Background: Precision therapy for lung cancer requires comprehensive genomic analyses. Specific effects of targeted therapies have been reported in Asia populations, including Taiwanese, but genomic studies have rarely been performed in these populations. Method: We enrolled 72 patients with non-small cell lung cancer, of whom 61 had adenocarcinoma, 10 had squamous cell carcinoma, and 1 had combined adenocarcinoma and squamous cell carcinoma. Whole-exome or targeted gene sequencing was performed. To identify trunk mutations, we performed whole-exome sequencing in two tumor regions in four patients. Results: Nineteen known driver mutations in EGFR, PIK3CA, KRAS, CTNNB1, and MET were identified in 34 of the 72 tumors evaluated (47.22%). A comparison with the Cancer Genome Atlas dataset showed that EGFR was mutated at a much higher frequency in our cohort than in Caucasians, whereas KRAS and TP53 mutations were found in only 5.56% and 25% of our Taiwanese patients, respectively. We also identified new mutations in ARID1A, ARID2, CDK12, CHEK2, GNAS, H3F3A, KDM6A, KMT2C, NOTCH1, RB1, RBM10, RUNX1, SETD2, SF3B1, SMARCA4, THRAP3, TP53, and ZMYM2. Moreover, all ClinVar pathogenic variants were trunk mutations present in two regions of a tumor. RNA sequencing revealed that the trunk or branch genes were expressed at similar levels among different tumor regions.Conclusions: We identified novel variants potentially associated with lung cancer tumorigenesis. The specific mutation pattern in Taiwanese patients with non-small cell lung cancer may influence targeted therapies.
