Context Pulmonary large cell carcinoma (LCC) includes tumors not readily diagnosed as adenocarcinoma (ADC) or squamous cell carcinoma on morphologic grounds, without regard to immunophenotype, according to the World Health Organization (WHO). This ambiguous designation may cause confusion over selection of mutation testing and directed therapies. Several groups have proposed the use of immunohistochemistry (IHC) to recategorize LCC as ADC or squamous cell carcinoma; however, it remains unclear if strictly defined LCCs are a clinicopathologically distinct lung tumor subset. Objective —To compare the pathologic, molecular, and clinical features of 2 morphologically similar tumors: solid-subtype ADC and LCC. Design Tumors were included on the basis of solid growth pattern; tumors with squamous or neuroendocrine differentiation were excluded. Solid ADC (n = 42) and LCC (n = 57) were diagnosed by using WHO criteria (5 intracellular mucin droplets in ≥2 high-power fields for solid ADC) and tested for KRAS, EGFR, and ALK alterations. Results —Both solid ADC and LCC groups were dominated by tumors with “undifferentiated”-type morphology and both had a high frequency of thyroid transcription factor 1 expression. KRAS was mutated in 38% of solid ADCs versus 43% of LCCs (P = .62). One ALK-rearranged and 1 EGFR-mutated tumor were detected in the solid ADC and LCC groups, respectively. There were no significant differences in clinical features or outcomes; the prevalence of smoking in both groups was greater than 95%. Conclusions Other than a paucity of intracellular mucin, LCC lacking squamous or neuroendocrine differentiation is indistinguishable from solid-subtype ADC. We propose the reclassification of these tumors as mucin-poor solid adenocarcinomas.

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

Objective: The aim of the study was to evaluate the diagnostic value of soluble fragment of cytokeratin 19 (CYFRA21-1) tests in detecting non-small cell lung cancer (NSCLC), including squamous cell carcinoma, lung adenocarcinoma, and large cell carcinoma. Methods: The relevant studies were identified from PubMed, Embase and the Cochrane Library before November 2018. Summary estimates for sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio of CYFRA21-1 tests for the diagnosis of NSCLC were calculated using the random effects model. A summary receiver operating characteristic (SROC) curve was used to assess the overall effectiveness of the test. Meta-DiSc 1.4 and Stata11.0 were applied to the statistical analysis. Publication bias was detected using Egger’s test. Results: A total of 22 studies consisting of 7910 NSCLC patients (squamous cell carcinoma/lung adenocarcinoma/large cell carcinoma) and 2630 benign lesions patients that met the inclusion criteria were included. The meta-analysis showed that CYFRA21-1 tests had a relatively high accuracy for squamous cell carcinoma detection and a lower accuracy for lung adenocarcinoma detection. The overall sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio of CYFRA21-1 tests for squamous cell carcinoma detection were 0.72 (95% confidence interval (CI) 0.70, 0.74), 0.94 (95% CI 0.92, 0.95), 9.73 (95% CI 7.06, 13.40), 0.37 (95% CI 0.29, 0.47), and 27.30 (95% CI 17.68, 42.16), respectively. The area under the SROC curve was 0.9171 (Q* = 0.8500). No publication bias was tested in the squamous cell carcinoma (P = 0.567) and lung adenocarcinoma (P = 0.378) groups. Conclusions: CYFRA21-1 tests might be appropriate for detecting squamous cell carcinoma.

The antineoplastic activity of vindesine was evaluated in 57 patients with non-small-cell carcinoma of the lung. 53 patients were fully evaluable for response and toxicity. Twenty-seven patients had squamous cell carcinoma (WHO I), 14 had adenocarcinoma (WHO III), and 12 had large cell carcinoma (WHO IV). Forty percent of patients were previously treated. Vindesine was administered at a weekly i.v. dose of 3 mg/m2. Partial remissions were observed in 2 of 12 patients with large cell carcinoma and in 1 of 27 patients with squamous cell carcinoma. Among 14 patients with adenocarcinoma, 3 minor responses were observed. Drug-related toxic effects (mainly leukopenia with manageable and reversible neurotoxicity) required modification of dose in 41 % of patients: this finding and previous treatment may have adversely affected the response rate. It is concluded that vindesine as a single agent has some activity in large cell carcinoma. Activity in the other histologic types was minimal but not totally absent and deserves further evaluation, possibly in non-pretreated patients.

Background: Lung cancer is the most common cancer causing deaths in men and women world-wide, responsible for over 1 million deaths annually. Although, advances in surgical techniques and combined therapies lung cancer remains a disease with a poor prognosis. Aim of the study was to evaluate the clinico-epidemiological and pathological profile in diagnosed case of lung cancer patients, presenting in the K N Chest hospital.Methods: Initial evaluation after obtaining informed consent, demography, history, clinicoradiological findings of patients and relevant investigations was recorded. Histopathological reports reviewed.Results: Our study included 108 patients with confirmed cases of lung cancer.The mean age of the patients was 57.50 years. The male:  female ratio was 5.8:1. Cough was the most common presenting symptom (77.78%) followed by chest pain (62.33%). Clubbing was most commonly associated with squamous cell carcinoma. Most common radiological presentation was consolidation (42.59%) followed by mass lesion (30.55%). Most common histopathological type of lung cancer found in this study was squamous cell carcinoma 47(43.52%) followed by adenocarcinoma 42 (38.89%). Small cell carcinoma was present in 15 (13.89%) and large cell carcinoma was present in 4 (3.70%) study group. The most common pathological cell type in silica dust exposed patient in this study was squamous cell carcinoma followed by adenocarcinoma with occupational history of > 10 years of silica dust exposure in stone mines.Conclusions: Squamous cell carcinoma still remains the commonest histological subtype followed by adenocarcinoma.
