e17525 Background: In 1999, we reported demographics, staging, and treatment outcomes of patients with mixed histology small cell lung cancer (MHSCLC). The purpose of this abstract is to report pattern of presentation and survival in patients during 2000-2009. Methods: Records from 24 patients diagnosed with MHSCLC were reviewed under an institutional review board outcomes study. One patient was excluded as records were missing. Patient and disease characteristics, treatment, and outcomes were analyzed. Results: Twenty-three patients were analyzed, with median age at diagnosis of 63 (range 50 to 84). Twenty (86%) patients were Caucasian. Fourteen (61%) patients were female, 9 (39%) were male. Twenty-one (91%) patients were current or former smokers. Staging was as follows: 1-2: 3, 3: 6, 4: 11, extensive-stage: 1, limited-stage: 2. Sites of diagnosis were lung in 18 (78%), and metastatic sites in 5 (22%). Presenting symptoms were cough or shortness of breath in 12 (52%), CNS in 4 (17%), chest pain in 2 (9%), various others in 5 patients. Paraneoplastic syndrome was seen in 2 patients, and 6 patients reported weight loss of 10-15 lbs within 3-6 months of diagnosis. Metastatic presentation was as follows: 4 brain, 1 bone, and 1 soft tissue. Histology included 15 large cell, 6 adenocarcinoma, and 1 squamous cell. Seventeen patients were treated as follows: chemotherapy (14), 5 thoracic radiotherapy (RT), 3 cranial RT, with treatment status unknown in 1 patient with 3 year survival. Twenty-one (91%) patients had expired, with median survival of 4.6 months (range <1 month-53 months). Two patients were alive at 24.1 and 38.5 months. Conclusions: This review revealed female predominance, which is in line with the increasing number of women diagnosed with small cell lung cancer (SCLC), but could be due to exclusion of veteran administration patients. Best survival was seen in one patient with squamous cell carcinoma, followed by patients with adenocarcinoma, opening a possible role for targeted biologics in this subset of MHSCLC. In memory of Michael Perry, MD, 1945-2011, dedicated physician, researcher, and teacher who started as primary mentor on this project before his passing.

In the United States, lung cancer is the second most common cancer, surpassed only by prostate cancer in men and breast cancer in women. But lung cancer is the leading cause of cancer deaths, accounting for 29% and 26% of all cancer-related deaths in men and women, respectively. The four major pathologic cell types of lung cancer are small cell carcinoma, adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Because they have overlapping clinical behaviors and responses to treatment, adenocarcinoma, squamous cell carcinoma, and large cell carcinoma are generally grouped together in the category of non–small cell lung cancer (NSCLC). This review discusses both NSCLC and small cell lung cancer (SCLC), including lung cancer in those who have never smoked, prevention of lung cancer, with sections on diagnosis, biomarkers, treatment, and supportive care.  This review contains 7 figures, 10 tables, and 74 references. Keywords: lung cancer, mediastinoscopy, chemoradiotherapy, TNM staging system, pulmonary parenchyma, segmentectomy

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&lt;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&lt;0.001), and an increase in adenocarcinoma (1021 cases [19.4%] vs. 609 [11.6%], p&lt;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.

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.

(1) Background: Despite the complementarity between radiology and histopathology, both from a diagnostic and a prognostic perspective, quantitative analyses of these modalities are usually performed in disconnected silos. This work presents initial results for differentiating two major non-small cell lung cancer (NSCLC) subtypes by exploring cross-scale associations between Computed Tomography (CT) images and corresponding digitized pathology images. (2) Methods: The analysis comprised three phases, (i) a multi-resolution cell density quantification to identify discriminant pathomic patterns for differentiating adenocarcinoma (ADC) and squamous cell carcinoma (SCC), (ii) radiomic characterization of CT images by using Haralick descriptors to quantify tumor textural heterogeneity as represented by gray-level co-occurrences to discriminate the two pathological subtypes, and (iii) quantitative correlation analysis between the multi-modal features to identify potential associations between them. This analysis was carried out using two publicly available digitized pathology databases (117 cases from TCGA and 54 cases from CPTAC) and a public radiological collection of CT images (101 cases from NSCLC-R). (3) Results: The top-ranked cell density pathomic features from the histopathology analysis were correlation, contrast, homogeneity, sum of entropy and difference of variance; which yielded a cross-validated AUC of 0.72 ± 0.02 on the training set (CPTAC) and hold-out validation AUC of 0.77 on the testing set (TCGA). Top-ranked co-occurrence radiomic features within NSCLC-R were contrast, correlation and sum of entropy which yielded a cross-validated AUC of 0.72 ± 0.01. Preliminary but significant cross-scale associations were identified between cell density statistics and CT intensity values using matched specimens available in the TCGA cohort, which were used to significantly improve the overall discriminatory performance of radiomic features in differentiating NSCLC subtypes (AUC = 0.78 ± 0.01). (4) Conclusions: Initial results suggest that cross-scale associations may exist between digital pathology and CT imaging which can be used to identify relevant radiomic and histopathology features to accurately distinguish lung adenocarcinomas from squamous cell carcinomas.
