Abstract
The aim of the present study was to analyze and summarize the clinicopathological characteristics of large-cell lung carcinoma (LCLC) of the lung, in order to improve the definite diagnosis rate of LCLC. Clinicopathological data of 174 patients with LCLC, confirmed pathologically, were retrospectively reviewed. The 174 cases of LCLC accounted for 5.7% of the total lung cancer cases during the corresponding time period at the Affiliated Cancer Hospital of Tianjin Medical University (Tianjin, China), among which there were 131 males and 43 females with an average age of 61.4 years. The postoperative pathological diagnosis of the 174 cases showed 80 cases of classic LCLC, 64 cases of large cell neuroendocrine carcinoma (LCNEC), six cases of combined LCNEC, 19 cases of basaloid carcinoma, three cases of clear cell carcinoma and two cases of lymphoepithelioma-like carcinoma. Of the total 174 LCLC cases, 96 patients exhibited lymph node metastasis. LCLC is a highly aggressive malignancy with a high tendency of invasion and metastasis, although the incidence rate is low. A definite diagnosis of LCLC primarily relies on the pathological diagnosis. Each subtype of LCLC has its own pathomorphological and immunohistochemical characteristics.

Among the 69 patients that underwent a fiber bronchoscope biopsy, three cases were diagnosed as large‐cell lung carcinoma (LCLC), one case was diagnosed as combined small‐cell lung carcinoma (SCLC), two cases were diagnosed as squamous cell carcinoma and three cases were diagnosed as poorly differentiated carcinoma
Among the 21 cases that received a simultaneous lung puncture biopsy, there were four cases of LCLC supported by immunohistochemistry, one case of neuroendocrine carcinoma and three cases of poorly differentiated carcinoma
Summary
Lung cancer is one of the most common malignancies worldwide, of which the incidence rate and mortality rank are the. The clinicopathological data from 174 patients with LCLC were retrospectively analyzed, with the aim of summarizing the specific clinicopathological features of LCLC and thereby improving the definite diagnosis rate of LCLC
