Analysis of unexpected small cell lung cancer following surgery as the primary treatment.

J Cancer Res Clin Oncol 2018 Dec 20;144(12):2441-2447. Epub 2018 Oct 20.

Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiaotong University, No. 241, West Huaihai Street, Xuhui District, Shanghai, 200030, China.

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

Daganatpatológiai Központ, Országos Onkológiai Intézet, Citopatológiai Osztály, Budapest, Hungary.

The heterogeneous group of lung neuroendocrine tumors are divided into four main types: typical carcinoid (TC), atypical carcinoid (AC), large cell neuroendocrine carcinoma (LCNEC), and small cell carcinoma (SCLC). Classification is based on the analysis of surgical resection specimens, which, in addition to basic morphological features, takes into account the mitotic count in 2 mm², the presence or absence of necrosis. According to prognosis, TC is low grade, AC is intermediate grade, while SCLC and LCNEC are high grade carcinomas with very poor prognosis. Read More

Endocrine paraneoplastic syndromes in lung cancer.

Hormones (Athens) 2018 Sep 2;17(3):351-358. Epub 2018 Jul 2.

Pulmonary Department, G. Papanikolaou Hospital, Aristotle University of Thessaloniki, Exohi, 570 10, Thessaloniki, Greece.

Paraneoplastic syndromes are defined as a combination of clinical disorders associated with malignant diseases that are caused by the secretion of various substances by the tumor without, however, being caused by the direct growth and infiltration of the primary tumor, or due to the development of distant metastases. Despite the fact that lung cancer represents the number one cause of death from cancer worldwide, the new methods of treatment increase patient survival and the incidence of paraneoplastic syndromes. The most important ones of these are humoral hypercalcemia of malignancy, syndrome of inappropriate antidiuretic hormone, hyponatremia of malignancy, ectopic Cushing's syndrome, carcinoid syndrome, and hypoglycemia and are usually a poor prognostic marker.

Updates on Selected Topics in Lung Cancers: Air Space Invasion in Adenocarcinoma and Ki-67 Staining in Carcinoid Tumors.

Arch Pathol Lab Med 2018 Aug 5;142(8):947-951. Epub 2018 Jun 5.

From the Division of Anatomic Pathology, Mayo Clinic Rochester, Rochester, Minnesota (Dr Yi); and the Department of Pathology, National Cancer Center Korea, Goyang-si, Korea (Dr Lee).

Context: - Air space invasion or aerogenous spread of lung adenocarcinoma is a relatively new concept and has been implicated as a potential prognostic factor as well as has been added as an exclusion point in the diagnosis of minimally invasive adenocarcinoma. Potential role for Ki-67 immunostaining as a diagnostic and prognostic marker in pulmonary carcinoid tumors has been suggested in the literature, given the significant interobserver variability and the difficulty in predicting their clinical behavior.

Objective: - To review the concept of air space invasion in lung adenocarcinoma and the current controversies regarding the role of Ki-67 immunostaining on pulmonary carcinoid tumors Data Sources. Read More

Bronchial carcinoid in anomalous right upper bronchus: a "patient-tailored" bronchoplasty resection technique.

J Vis Surg 2018 27;4:81. Epub 2018 Apr 27.

Department of Thoracic Surgery, European Institute of Oncology, Milan, Italy.

Bronchial carcinoids (BC) are indolent neuroendocrine tumors (NET) that are classified as malignant because they can locally infiltrate and metastasize. Resection is the primary treatment for most localized carcinoid tumors, with lung parenchymal-sparing surgery the favoured objective for patients with central airway tumors. Sleeve bronchoplasty techniques are complex surgical procedures defined as parenchyma-saving because they allow a radical resection with tumor-free margins while preserving the maximum amount of parenchyma.

Clinical and Pathologic Characteristics of Pulmonary Carcinoid Tumors in Central and Peripheral Locations.

Endocr Pathol 2018 Sep;29(3):259-268

Department of Cellular Pathology, Guy's and St Thomas' NHS Foundation Trust, London, UK.

Pulmonary carcinoid tumors occur in both central and peripheral locations, and some differences in clinico-pathological features have long been observed. We investigated a large number of resected carcinoid tumors with the aim to further define the characteristics of tumors from both locations. One hundred sixty-six resected carcinoid tumors of the lung were analyzed for a variety of clinical and pathologic features, including histology subtype, mitotic rate, Ki67 index, necrosis, invasive pattern, architectural pattern, cell morphology, sustentacular cells, neuroendocrine hyperplasia, and orthopedia homeobox protein (OTP) and TTF-1 immunohistochemical expressions.

Two types of ectopic Cushing syndrome or a continuum? Review.

Pituitary 2018 Oct;21(5):535-544

Department Endocrinology, Hospital Universitario de la Princesa, Madrid, Spain.

Background: Two types of ectopic Cushing syndrome (ECS) are described: ECS associated with aggressive neoplasms, and ECS with indolent and occult tumors, however, there is a lack of studies that thoroughly review their characteristics.

Methods: A systematic review was carried out on PUBMED of all the papers about the ECS, in order to better define the types of this subcategory of Cushing's syndrome, highlighting the differential aspects between these subgroups.

Results: It was found that in 50% of cases the prototypic "aggressive" ECS is caused by small cell lung carcinomas (SCLC). Read More

The Ectopic Adrenocorticotropic Hormone Syndrome: Rarely Easy, Always Challenging.

Endocrinol Metab Clin North Am 2018 06;47(2):409-425

Neuroendocrine Tumour Unit, Royal Free Hospital, Pond Street, London NW3 2QG, UK. Electronic address:

Despite modern imaging techniques, differentiating ectopic adrenocorticotropic hormone (ACTH) syndrome from pituitary-dependent Cushing's syndrome, Cushing's disease, is especially difficult when well-differentiated carcinoids are the source of ACTH secretion, particularly pulmonary carcinoid tumors. ACTH-secreting pulmonary carcinoids, like the corticotroph adenomas causing Cushing's disease, are often small and difficult to detect, and patients present with a gradual onset of the classical signs and symptoms of Cushing's syndrome, indistinguishable from the presentation of Cushing's disease. Hence, the differential diagnosis relies on a combination of clinical assessment, dynamic biochemical tests, inferior petrosal sinus sampling, and multimodal imaging, each with its own caveats and pitfalls.
