Large cell neuroendocrine cancer (LCNEC) of the lung exhibits morphological and immunohistochemical characteristics of both neuroendocrine and large cell carcinomas. No defined optimal therapy has been described for this subset of patients and the question of whether these patients should be treated with non-small cell lung cancer (NSCLC) treatment protocols, according to the National Comprehensive Cancer Network (NCCN) guidelines, or with small cell lung cancer (SCLC) due to histological and clinical similarities is still uncertain. We conducted a retrospective review of patients identified with diagnosis of LCNEC of the lung at the University of Cincinnati Cancer Center from the year 2002 to 2012 to determine which treatment approach resulted in improved outcomes in this rare category of disease. Patients who received chemotherapy whether NSCLC (group A) or SCLC (group B) protocols did not show significant changes in OS (P=0.911). Meanwhile, patients who underwent surgery (group C) had better OS compared to groups A and B (P= 0.027 and 0.024, respectively). This analysis reveals that outcomes for SCLC or NSCLC treatment strategies in LCNEC patients did not result in survival advantages and future research should be addressing it as a separate entity.

7136 Background: Metastasis to the brain is the most common intracranial tumour and 20–40% of all cancer patients will develop brain metastases. Lung cancer is the most common primary tumour and compose of 40%-50% of all brain metasases. As the survival in many malignancies increases, brain metastases will be an increasing problem. It is therefore important to find new treatment options. The aim of this study was primary to study quality of life and to compare radiotherapy and Themozolomide in that context. Methods: Inclusion criterias were confirmed small cell or non-small cell lung cancer, multiple brain metastases, PS 0–2, no previous radiotherapy to the brain. Previous chemotherapy was allowed. Patients were randomized to arm A (radiotherapy 30 Gy over 10 fractions) or arm B (Temozolomide 200 mg/m2 day 1–5, new cycle on day 29). Quality of life (QoL) was measured with a general cancer module, EORTC QLQ-C30, and a brain cancer specific module, BCM20. The primary end-point was the proportion of patients in each treatment arm with maintained or better QoL score at 8 weeks compared to the base line evaluation. In this first analysis exclusion rate from the study at 8 weeks was used as a surrogate end-point. Results: 208 patients were included, 104 in arm A and 104 in arm B. 36 (17%) squamous cell, 97 (47%) adenocarcinomas, 10 (5%) large cell, 23 (11%) undifferentiated and 42 (20%) small-cell lung cancer were included. 93 (45%) patients were chemonaive. At 8 weeks, 79 patients were excluded from the study, 51 (49%) from the temozolomide arm and 28 (27%) from the radiotherapy arm. 53% of the patients with squamous cell carcinoma were excluded compared to 40% of small cell lung cancer, 33% of adenocarcinomas and 27% of large cell carcinomas. The exclusion rate at 8 weeks was higher among patients with symptoms at randomization compared to patients without symptoms. There were no difference in exclusion rate when comparing number or size of the metastases. Conclusion: The exclusion rate at 8 weeks was higher in the temozolomide arm compared to the radiotherapy arm. Histopathology and symptoms at randomization seems to be factors influencing the exclusion rate whereas number or size of metastases does not. Survival and quality of life data will be presented at the meeting. No significant financial relationships to disclose.

In the late stages of non-small cell lung cancer, the detection of sensitizing mutations of the epidermal growth factor receptor (EGFR) is mandatory to select patients’ treatment with first- or second-generation tyrosine kinase inhibitors (TKIs). In patients showing progressive disease, the assessment of the EGFR exon 20 resistance point mutation p.T790M is required for third-generation TKI administration. However, molecular analysis does not capture all the different mechanisms of resistance against these molecules. A variety of morphological changes associated with acquired resistance have also been described. Since an altered morphology may be the only clue to acquired resistance, cytopathology still plays a relevant role in this setting. In this comprehensive review, we have focused on the relevance of squamous cell carcinoma, small cell lung cancer and large-cell neuroendocrine carcinoma transitions from adenocarcinoma resistant to TKIs.

BackgroundPulmonary large cell neuroendocrine cancer (LCNEC) is commonly classified as non-small cell lung cancer (NSCLC). Even for stage I disease, after surgery the survival is always poor, but clinical research on LCNEC is scant and always with unsatisfying sample sizes. Thus, we conduct the first study using the Surveillance, Epidemiology, and End Results (SEER) database to compare survival after surgery between stage I LCNEC and other types of NSCLC.MethodsFrom 2004 to 2016, 473 patients with stage IA LCNEC, 17,669 patients with lung adenocarcinoma (LADC) and 8,475 patients with lung squamous cell cancer (LSCC), all treated with surgery were identified. In addition, 1:1 PSM was used, and overall (OS) and cancer-specific survival (CSS) between groups were compared.ResultsThe 5-year OS rates and CSS rates for LCNEC were 52.5% and 81.5%, respectively. Overall, both OS and CSS were significantly superior for stage IA LADC than LCNEC (for OS: HR 0.636, 95% CI 0.568-0.712; for CSS: HR 0.688, 95% CI 0.561–0.842, LCNEC as reference), while comparable for LSCC with LCNEC (for OS: HR 0.974, 95% CI 0.869–1.091; for CSS: HR 0.907, 95% CI 0.738–1.115). PSM generated 471 pairs when LCNEC was compared with LADC and both OS and CSS were significantly better in LADC than LCNEC (for OS: HR 0.580, 95% CI 0.491–0.686; for CSS: HR 0.602, 95% CI 0.446–0.814). Of note, for the subgroup of patients ≤ 65 years old, HRs for both OS and CSS were lower (for OS: HR 0.470; for CSS: HR 0.482). As for comparison between LCNEC and LSCC, PSM generated 470 pairs. Differently, only CSS was significantly superior in LSCC than LCNEC (HR 0.563, 95% CI 0.392–0.807), while OS was not. Further grouping by age showed only CSS between two groups for patients with age ≤ 65 years old was significantly different (P = 0.006).ConclusionsWe report the first survival comparison after surgery between stage IA LCNEC and other types of NSCLC by SEER database and PSM. Our results demonstrated after surgery, stage IA LCNEC was worse in survival, especially compared to LADC. Extra clinical care should be paid, especially for younger patients. More studies investigating adjuvant therapy are warranted.

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

Abstract Objective.—To study the immunoreactivity profile of the neuron-associated class III β-tubulin isotype (β III) in epithelial lung tumors. Design.—One hundred four formalin-fixed, paraffin-embedded primary and metastatic lung cancer specimens were immunostained with an anti–β III mouse monoclonal antibody (TuJ1) and an anti–β III affinity-purified rabbit antiserum. Paraffin sections from fetal, infantile, and adult nonneoplastic lung tissues were also examined. Results.—In the fetal airway epithelium, β III staining is detected transiently in rare Kulchitsky-like cells from lung tissues corresponding to the pseudoglandular and canalicular but not the saccular or alveolar stages of development. β III is absent in healthy, hyperplastic, metaplastic, and dysplastic airway epithelium of the adult lung. In contrast, β III is highly expressed in small cell lung cancer, large cell neuroendocrine carcinoma, and in some non–small cell lung cancers, particularly adenocarcinomas. There is no correlation between expression of β III and generic neuroendocrine markers, such as chromogranin A and/or synaptophysin, in pulmonary adenocarcinomas. Also, focal β III staining is present in primary and metastatic adenocarcinomas (to the lung) originating in the colon, prostate, and ovary. β III is expressed to a much lesser extent in atypical carcinoids and is rarely detectable in typical carcinoids and squamous cell carcinomas of the lung. The distribution of β III in small cell lung cancer and adenocarcinoma metastases to regional lymph nodes and brain approaches 100% of tumor cells, which is substantially greater than in the primary tumors. Conclusions.—In the context of neuroendocrine lung tumors, β III immunoreactivity is a molecular signature of high-grade malignant neoplasms (small cell lung cancer and large cell neuroendocrine carcinoma) although its importance in atypical carcinoids must be evaluated further. In addition, β III may be a useful diagnostic marker in distinguishing between small cell lung cancers and certain non–small cell lung cancers (poorly differentiated squamous cell carcinomas), especially in small biopsy specimens. To our knowledge, β III is the only tumor biomarker that exhibits a substantially more widespread distribution in poorly differentiated than in better differentiated pulmonary neuroendocrine tumors. However, the significance of β III phenotypes in non–small cell lung cancer, particularly adenocarcinoma, with respect to neuroendocrine differentiation and prognostic value, requires further evaluation.
