A partial or complete resolution of the neoplastic lesion, either spontaneously or in the presence of therapy that is considered inadequate to exert significant influence on the growth of the neoplastic lesion, is considered a spontaneous regression. This phenomenon is extremely rare in lung neoplasms. A close follow up with imaging along with bronchoscopy and a biopsy of the lesion is essential, as they may have potential for distant spread even during radiological regression. Read More

The diagnostic criteria of lung biopsy specimens by 2015 WHO lung tumor classification were used to evaluate lung biopsy specimens along with detection of genetic alterations of major tumor driving genes including epidermal growth factor receptor (EGFR). The clinical data, histological slides, immunohistochemical stains and special stains of 806 lung biopsy specimens at Beijing Hospital from July 2015 to July 2018 were retrospectively analyzed. Diagnosis of lung cancer was reclassified according to the 2015 WHO lung tumor classification and related gene mutation data were analyzed. Read More

Purpose: Neuroendocrine lung tumors (NET) include typical carcinoids (TC), atypical carcinoids (AC), large cell NE carcinoma (LCNEC) and small-cell carcinoma (SCLC), with different clinicopathological profiles and relative grades of malignancy. Although differences between carcinoids and high grade carcinomas are recognized, precise differences and behavior of TC and AC have not been clearly defined. The aim of this study was to better define the differences in the clinical behavior of TC and AC, and to establish new prognostic factors of overall survival (OS), by determining the levels of genetic expression of IGF1R, ERCC1, Bax, p53, Bcl2 and Bcl2/Bax ratio.

Introduction: Orthopedia homeobox protein (OTP) was recently demonstrated to be a pulmonary neuroendocrine marker showing specificity for pulmonary carcinoid tumors in histologic sections. Little is known of OTP performance and specificity for pulmonary neuroendocrine tumors in lung fine-needle aspiration (FNA) cell blocks (CBs), however.

Materials And Methods: We evaluated OTP expression in lung non-neuroendocrine and neuroendocrine tumor CBs to determine its diagnostic utility in these specimens. Read More

The spectrum and evolution of proliferation rates in stage IV lung carcinoids is poorly defined. In particular, there are limited data on the prevalence and characteristics of tumors exceeding the standard upper proliferative criteria-as defined largely based on early-stage carcinoids-in metastatic setting. Sixty-six patients with stage IV lung carcinoids were identified, and all evaluable samples (n = 132; mean 2 samples per patient) were analyzed for mitotic counts and Ki-67 rate. Read More

Background: Pulmonary carcinoids (PC) are histologically classified into typical carcinoid (TC) and atypical carcinoid (AC). The diagnosis of pulmonary carcinoid and possibly the differentiation between TC and AC could make a significant effect on the treatment planning as well as prognosis. Several studies have explored the utility of Ga-DOTA-Peptide (Ga-labelled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-peptide) and F-flurodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the evaluation of primary pulmonary carcinoids.

Background: Large cell neuroendocrine carcinoma (LCNEC) was categorized into pulmonary neuroendocrine tumors (NETs) according to the World Health Organization classification guideline. However, LCNEC patients often received the chemotherapy regimens similar to non-small cell lung carcinoma (NSCLC) in advanced stage and the therapeutic effect was unsatisfactory. Therefore, this study aimed to investigate the hidden clinical features, prognosis and immunoprofile of the LCNEC, compared with carcinoid and SCLC, to explore whether LCNEC shares similarity with SCLC and potential treatment approaches could be revealed.

Background: Classification of the pulmonary neuroendocrine tumor (pNET) categories is a step-wise process identified by the presence of necrosis and number of mitoses per 2 mm. In neuroendocrine tumor pathology, Ki-67 was first described as a prognostic factor in the pancreas and incorporated into the grading system of digestive tract neuroendocrine neoplasms in the 2010 WHO classification. However, the significance of Ki-67 in pNETs was still a controversial issue. Read More

The clinicopathological features of lung neuroendocrine neoplasms (NEN) with a high proliferative index at the border area between atypical carcinoid and neuroendocrine carcinoma have not been investigated so far. The aim of this study was, therefore, to search for lung NENs which are well differentiated but show Ki67 values that overlap with those of poorly differentiated (PD)-NENs. Resected lung NENs from 244 Japanese patients were reviewed, and Ki67 indices were assessed in all tumors. Read More

Purpose: Small cell lung cancer (SCLC) is considered a systemic disease and surgery is generally not recommended to treat it. High heterogeneity within the tumor and preoperative diagnostic capabilities can sometimes fail to identify SCLC correctly, leading to a subset of unexpected SCLC patients that are diagnosed only after pulmonary resections.

Methods: We retrospectively reviewed the clinical records of patients who were diagnosed as having SCLC only after surgery between 2008 and 2015 at a single institution. Read More

A 40-year-old male was referred to our hospital because of a nodular shadow detected in the left lower lobe with the tendency to increase gently. Because fluoro-2-deoxy-D-glucose (FDG) uptake was extremely low on a FDG positron emission tomography (PET-CT), the tumor was highly suspected of the benign tumor. Five years later, a follow-up computed tomography (CT) showed the shadow to be enlarged. Read More
