Ockham's Razor for a Retinal Lesion and Acromegaly and Breaking the Vicious Circle.

J Endocr Soc 2022 Jul 3;6(7):bvac083. Epub 2022 Jun 3.

Centre for Endocrinology, William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, UK.

Acromegaly due to ectopic secretion of growth hormone-releasing hormone (GHRH) is rare. Treatment consists of surgical removal of the primary tumor, cytostatic therapy, "cold" or radioactive somatostatin analogue treatment, and medical therapy for acromegaly, if needed. A 53 year-old female had an ocular lesion noted on a routine optician visit, originally considered to be an ocular melanoma. Read More

To compare the respective value of Ga-DOTATOC and F-DOPA PET/CT for initial staging or pre-surgical work-up of patients with small intestine neuroendocrine tumors (SiNET). This is a retrospective, multicenter, non-interventional investigation involving 53 non-operated SiNET patients who underwent both Ga-DOTATOC and F-DOPA PET/CT within a 6-months interval without therapeutic intervention or change between the two PET/CT studies. Detection rate (DR %) was calculated according to per-region and per-lesion analyses. Read More

Incidental pulmonary carcinoid tumorlet associated with lung cancer.

Medicina (B Aires) 2022 ;82(2):297-299

Servicio de Cirugía Torácica, Hospital Británico de Buenos Aires, Argentina.

Lung tumorlets are rare neuroendocrine neoplasms of 0.5 cm or less in diameter that extend beyond the basement membrane. Although they are associated with bronchiectasis and fibrosis they tend to be asymptomatic and behave in a benign way, usually being diagnosed as incidental microscopic nests of neuroendocrine cells in lung tissue.

Secretin Receptor as a Target in Gastrointestinal Cancer: Expression Analysis and Ligand Development.

Biomedicines 2022 Feb 24;10(3). Epub 2022 Feb 24.

Department of Hepatology and Gastroenterology, Charité-Universitätsmedizin Berlin, 13353 Berlin, Germany.

Secretin was originally discovered as a gastrointestinal peptide that stimulates fluid secretion from the pancreas and liver and delays gastric emptying. In disease, a secretin receptor (SCTR) was found to occur as a splice variant in gastrinoma and pancreatic adenocarcinoma. Overexpression of SCTR has been described for gastrinomas, carcinoid tumors of the lung and cholangiocarcinoma. Read More

Service of Pulmonology, Instituto Português de Oncologia do Porto, Portugal.

Primary carcinoid tumours of the lung are rare tumours and when typical are associated with a benign behaviour and should be classified as low-grade neuroendocrine tumour/carcinoma. A 67-year old HIV-positive female was admitted due to a typical carcinoid tumour on the distal third of the main left bronchus, occupying two thirds of the lumen. Given she was HIV positive, had a moderately compromised lung function and in order to minimize surgical events, postoperative complications and to maximize postoperative lung function, the authors opted for a bronchoplasty using a patch.

Indocyanine Green Labeling of Tumors in the Liver Recurring After Radiofrequency Ablation Enables Complete Resection by Fluorescence-guided Surgery.

Anticancer Res 2022 Mar;42(3):1345-1350

Department of Surgery, University of California, San Diego, CA, U.S.A.

Background/aim: Radiofrequency ablation (RFA) is used to treat primary and metastatic tumors in the liver. However, local recurrence after RFA is frequent and subsequent salvage hepatectomy is often ineffective due to difficulty in visualization of tumor margins.

Patients And Methods: In the present retrospective clinical trial, seven patients from the Department of General and Gastro-enterological Surgery, Showa University School of Medicine underwent salvage hepatectomy for recurrent hepatocellular carcinoma (HCC) (n=2), colorectal liver metastasis (n=4) and lung-carcinoid liver metastasis (n=1), after RFA, between 2011 and 2020.

Division of Pulmonary and Critical Care, St. Luke's University Health Network, Bethlehem, PA, USA.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is an atypical pulmonary disorder with limited understanding. Given the rare nature of this disease, it is essential to obtain adequate tissue pathology to confirm the diagnosis. This disease is mainly diagnosed in middle-aged, nonsmoking females, and it is now accepted as a precursor lesion to pulmonary carcinoid tumors. Read More

Pearls and Pitfalls in Lung Cancer Imaging.

Semin Ultrasound CT MR 2021 Dec 7;42(6):524-534. Epub 2021 May 7.

University of Kansas Medical Center, Department of Radiology, Kansas City, KS.

Imaging plays an essential role in the diagnosis and staging of pulmonary malignancy. Familiarity of less common manifestations of lung cancer including subsolid nodule, consolidation, and cyst associated lung cancer is important to avoid delayed diagnosis and improve patient outcomes. In this article, we review the staging of multifocal lung cancer, PET negative lung cancers (carcinoid and indolent lung adenocarcinoma), and false positive lymph nodes on PET due to infectious and inflammatory etiologies.

MR Three-Territory Sign in Cancer-Associated Hypercoagulation Stroke (Trousseau Syndrome): An Overlooked Diagnostic Feature: MR Three-Territory Sign.

Neurologist 2021 Nov 26;27(2):37-40. Epub 2021 Nov 26.

Department of Neurology, Hartford Hospital and University of Connecticut School of Medicine, Hartford, CT.

Background: Stroke in the setting of three-territory lesion pattern on magnetic resonance-diffusion-weighted imaging "three-territory sign" (TTS) is predominately due to cancer-associated hypercoagulation (CAH). Our goal is to determine the frequency with which "TTS" is overlooked as a diagnostic feature of cancer-associated hypercoagulation stroke.

Methods: Over a 4-year period (October 2016 to October 2020), stroke admissions with magnetic resonance imaging defined three-territory diffusion-weighted imaging lesions were identified. Read More

Video-assisted thoracic surgery sleeve resection and bronchoplasty using 3D imaging system: its safety and efficacy.

J Cardiothorac Surg 2021 Oct 16;16(1):302. Epub 2021 Oct 16.

Department of Thoracic and Cardiovascular Surgery, Seoul National University Bundang Hospital, Seoul National University College of Medicine, Seoul, Korea.

Background: Video-assisted thoracic surgery sleeve resection with bronchial anastomosis or bronchoplasty is a technically demanding procedure. Three-dimensional endoscopic surgery has been reported to be helpful in decreasing operation time and improving spatial perception with less surgical errors, but there have been rare reports about relatively difficult thoracoscopic procedures utilizing 3D thoracoscope. We performed this study to evaluate early clinical outcomes of thoracoscopic sleeve resection and bronchoplasty utilizing 3D thoracoscope. Read More

Transl Biophotonics 2020 Nov 21;2(4):e202000009. Epub 2020 Aug 21.

Faculty of Science, Department of Physics, LaserLab Vrije Universiteit Amsterdam Amsterdam Netherlands.

During lung cancer operations a rapid and reliable assessment of tumor tissue can reduce operation time and potentially improve patient outcomes. We show that third harmonic generation (THG), second harmonic generation (SHG) and two-photon excited autofluorescence (2PEF) microscopy reveals relevant, histopathological information within seconds in fresh unprocessed human lung samples. We used a compact, portable microscope and recorded images within 1 to 3 seconds using a power of 5 mW. Read More

Potential for Increasing Uptake of Radiolabeled Ga-DOTATOC and I-MIBG in Patients with Midgut Neuroendocrine Tumors Using a Histone Deacetylase Inhibitor Vorinostat.

Cancer Biother Radiopharm 2021 Oct 12;36(8):632-641. Epub 2021 Jul 12.

Department of Radiology, University of Iowa Carver College of Medicine, Iowa City, Iowa, USA.

Histone deacetylase (HDAC) inhibitors have been shown in preclinical studies to upregulate norepinephrine transporters in neuroblastoma and pheochromocytoma, and somatostatin receptors in pulmonary carcinoid, small cell lung cancer, and pancreatic neuroendocrine malignancies. This pilot imaging study in humans focuses on midgut neuroendocrine carcinoma metastatic to the liver, evaluating the effect of pretreatment with the HDAC inhibitor vorinostat on uptake of I-MIBG and Ga-DOTATOC. Multiple midgut neuroendocrine liver metastases in clinically stable subjects were imaged with I-MIBG and Ga-DOTATOC before and after a 4-d course of vorinostat. Read More
