Confocal endomicroscopy and robot-assisted bronchoplasty integration to treat an endobronchial tumour.

Interact Cardiovasc Thorac Surg 2021 May 17. Epub 2021 May 17.

Thoracic Surgery Division, São Paulo State Cancer Institute, São Paulo, Brazil.

We present a case of a young man with an endobronchial carcinoid in the left main bronchus, which was treated integrating probe-based confocal laser endomicroscopy and fluorescence imaging during a robot-assisted bronchoplasty. This technique allowed precise detection of the neoplastic area, avoiding associated lung resection.

Type A thymoma with simultaneous solitary intrapulmonary metastasis: A case report.

Thorac Cancer 2021 Jun 7;12(12):1923-1926. Epub 2021 May 7.

Department of Oncology, Immunology and Surgery, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.

A 79-year-old woman was referred to our facility because of an abnormal chest shadow. Chest computed tomography (CT) showed a solitary right middle lung nodule with a maximum diameter of 3 mm and anterior mediastinal nodule with a maximum diameter of 21 mm. The lung nodule was suspected of being a primary lung cancer rather than a metastatic tumor because there were no primary malignant tumors, apart from an anterior mediastinal tumor visible on diagnostic imaging, including F fluorodeoxyglucose-positron emission tomography, and a solitary lung nodule.

Neuroendocrine Lung Cancer Mouse Models: An Overview.

Cancers (Basel) 2020 Dec 22;13(1). Epub 2020 Dec 22.

Molecular Oncology Unit (CIEMAT), Institute of Biomedical Research, University Hospital "12 de Octubre", CIBERONC, 28040 Madrid, Spain.

Neuroendocrine lung tumors comprise a range of malignancies that extend from benign tumorlets to the most prevalent and aggressive Small Cell Lung Carcinoma (SCLC). They also include low-grade Typical Carcinoids (TC), intermediate-grade Atypical Carcinoids (AC) and high-grade Large Cell Neuroendocrine Carcinoma (LCNEC). Optimal treatment options have not been adequately established: surgical resection when possible is the choice for AC and TC, and for SCLC chemotherapy and very recently, immune checkpoint inhibitors.

Incidental finding of MEN-1 syndrome during staging and follow-up of breast carcinoma.

BMJ Case Rep 2020 Dec 21;13(12). Epub 2020 Dec 21.

Surgery, Centro Hospitalar Lisboa Norte EPE, Lisboa, Portugal.

Type 1 multiple endocrine neoplasia (MEN-1) syndrome is an autosomal dominant disease, associated with germline mutations in the MEN-1 tumour suppressor gene (encoding the menin protein). Recent studies, through a better characterisation of the functions of the menin protein, have started to demonstrate how changes in this protein may be related to breast cancer. We present the case of a patient whose diagnosis of MEN-1 syndrome was made during treatment for a breast tumour-this diagnosis was obtained after finding multiple neoplastic lesions that fitted the MEN-1 syndrome spectrum, during the initial staging and subsequent follow-up of a breast tumour.

Eur J Cancer 2021 02 25;144:200-214. Epub 2020 Dec 25.

Department of Medical Oncology and Hematology, Odette Cancer Centre, Sunnybrook Health Sciences Centre, Toronto, Canada. Electronic address:

Neuroendocrine neoplasms (NENs) are a heterogeneous family of uncommon tumours with challenging diagnosis, clinical management and unique needs that almost always requires a multidisciplinary approach. In the absence of guidance from the scientific literature, along with the rapidly changing data available on the effect of COVID-19, we report how 12 high-volume NEN centres of expertise in 10 countries at different stages of the evolving COVID-19 global pandemic along with members of international neuroendocrine cancer patient societies have suggested to preserve high standards of care for patients with NENs. We review the multidisciplinary management of neuroendocrine neoplasms during the COVID-19 pandemic, and we suggest potential strategies to reduce risk and aid multidisciplinary treatment decision-making.

J Thorac Dis 2020 Nov;12(11):6978-6991

Department of Radiology, Mayo Clinic, Rochester, Minnesota, USA.

Ongoing technologic and therapeutic advancements in medicine are now testing the limits of conventional anatomic imaging techniques. The ability to image physiology, rather than simply anatomy, is critical in the management of multiple disease processes, especially in oncology. Nuclear medicine has assumed a leading role in detecting, diagnosing, staging and assessing treatment response of various pathologic entities, and appears well positioned to do so into the future.

Sclerosing pneumocytoma mixed with a columnar clear cell adenoma and a typical carcinoid: case report and review of literature.

Int J Clin Exp Pathol 2020 1;13(10):2599-2607. Epub 2020 Oct 1.

Department of Medicine, The Affiliated Yantai Yuhuangding Hospital of Qingdao University No. 20 East Yuhuangding Road, Yantai, Shandong, China.

Sclerosing pneumocytoma (SP) is a rare and benign tumor predominantly occurring in Asian women, easily misdiagnosed by imaging and pathologic frozen diagnosis during surgery because of its diverse histomorphology (4 structures, 2 types of cells). It may form multiple tumors. When SP is combined with carcinoid, adenoma, or other tumors (although rare), diagnosis is more complicated. Read More

Role of theranostics in thoracic oncology.

J Thorac Dis 2020 Sep;12(9):5140-5146

Department of Diagnostic and Interventional Radiology, City of Hope National Medical Center, Duarte, CA, USA.

Theranostics is a re-emerging field of medicine that aims to create targeted agents that can be used for diagnostic and/or therapeutic indications. In the past, theranostics has been used to treat neoplasms, such as thyroid cancer and neuroblastomas. More recently, theranostics has seen a resurgence with advent of new therapeutic antibodies and small molecules which can be transformed into Theranostic agents through radioconjugating with a radioactive isotope.

Fluorescence navigation with indocyanine green for identification of intersegmental planes using a photodynamic eye camera.

J Thorac Dis 2020 Sep;12(9):4817-4824

First Department of Surgery, Hamamatsu University School of Medicine, Hamamatsu, Japan.

Background: Pulmonary segmentectomy is an important surgical option for complete resection in patients with poor lung function. However, correctly recognizing the intersegmental plane for accurate segmentectomy is sometimes difficult. We therefore developed a novel method that allows the detection of intersegmental planes using an indocyanine green (ICG) fluorescence imaging device, photodynamic eye (PDE) camera, PDE-neo.
