Complex Immune Contextures Characterise Malignant Peritoneal Mesothelioma: Loss of Adaptive Immunological Signature in the More Aggressive Histological Types.

J Immunol Res 2018 29;2018:5804230. Epub 2018 Oct 29.

Unit of Immunotherapy of Human Tumours, Department of Experimental Oncology and Molecular Medicine, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Malignant peritoneal mesothelioma (MpM), arising in the setting of local inflammation, is a rare aggressive tumour with a poor prognosis and limited therapeutic options. The three major MpM histological variants, epithelioid (E-MpMs), biphasic, and sarcomatoid MpMs (S-MpMs), are characterised by an increased aggressiveness and enhanced levels of EZH2 expression. To investigate the MpM immune contexture along the spectrum of MpM histotypes, an extended in situ analysis was performed on a series of 14 cases. Read More

A combination of MTAP and BAP1 immunohistochemistry is effective for distinguishing sarcomatoid mesothelioma from fibrous pleuritis.

Lung Cancer 2018 Nov 26;125:198-204. Epub 2018 Sep 26.

Department of Pathology, Fukuoka University Hospital and School of Medicine, Fukuoka, Japan. Electronic address:

Objectives: Histologic diagnosis of malignant pleural mesothelioma (MPM) is not always straightforward. Loss of BRCA1-associated protein 1 (BAP1) expression as detected by immunohistochemistry (IHC) (BAP1 IHC) and homozygous deletion (HD) of 9p21 as detected by fluorescencein situ hybridization (FISH) (9p21 FISH) are effective for distinguishing malignant mesothelial proliferation from benign proliferation. We have previously reported that immunohistochemical expression of the protein product of the methylthioadenosine phosphorylase (MTAP) gene, which is localized in the 9p21 chromosomal region, is correlated with the deletion status of 9p21 FISH in MPM tissues.

Pleomorphic carcinoma of the lung mimicking synchronous pulmonary adenocarcinoma and small bowel sarcoma.

Ann Thorac Med 2018 Oct-Dec;13(4):251-253

Department of Pathology, Kyung Hee University Hospital at Gangdong, College of Medicine, Kyung Hee University, Seoul, Korea.

Pulmonary pleomorphic carcinoma is defined as a nonsmall cell lung carcinoma (NSCLC) that contains at least 10% sarcomatoid components. We report a case of pulmonary pleomorphic carcinoma of which only the sarcomatoid component metastasized to the small bowel and adenocarcinoma was identified on percutaneous transthoracic needle biopsy (PTNB). We suggest that if an NSCLC is diagnosed by PTNB and a sarcoma is found at another site, or vice versa, pulmonary pleomorphic carcinoma with a single metastasis should be considered as a differential diagnosis to establish the best effective treatment plan.

Activation of hepatocyte growth factor/MET signaling initiates oncogenic transformation and enhances tumoraggressiveness in the murine prostate.

J Biol Chem 2018 Nov 6. Epub 2018 Nov 6.

Cancer Biology, City of Hope, United States.

Emerging evidence has shown that the hepatocyte growth factor (HGF) and its receptor, MET proto-oncogene, receptor tyrosine kinase (MET), promote cell proliferation, motility, morphogenesis, and angiogenesis. While up-regulation of MET expression has been observed in aggressive and metastatic prostate cancer, a clear understanding of MET function in prostate tumorigenesis remains elusive. Here, we developed a conditional Met transgenic mouse strain, , to mimic human prostate cancer cells with increased MET expression in the prostatic luminal epithelium. Read More

Non-Clear Cell Renal Cell Carcinomas: From Shadow to Light.

J Clin Oncol 2018 Oct 29:JCO2018792531. Epub 2018 Oct 29.

Laurence Albiges and Ronan Flippot, Gustave Roussy, Université Paris-Saclay, Villejuif; Nathalie Rioux-Leclercq, Rennes University Hospital, Rennes, France; and Toni K. Choueiri, Dana-Farber Cancer Institute, Boston, MA.

Non-clear cell renal cell carcinomas (RCCs) account for up to 25% of kidney cancers and encompass distinct diseases with distinct pathologic features, different molecular alterations, and various patterns of response to systemic therapies. Recent advances in molecular biology and large collaborative efforts helped to better define the oncogenic mechanisms at play in papillary, chromophobe, collecting duct, medullary, translocation, and sarcomatoid RCCs. Papillary RCCs are divided into several subsets of tumors characterized by distinct gene expression profiles, chromatin remodeling genes, cell cycle changes, and alterations of the MET pathway.

mTOR and mTOR phosphorylation status in primary and metastatic renal cell carcinoma tissue: differential expression and clinical relevance.

J Cancer Res Clin Oncol 2018 Oct 27. Epub 2018 Oct 27.

Department of Urology, University Hospital Tübingen, Hoppe-Seyler-Str. 3, 72076, Tübingen, Germany.

Purpose: Impaired regulation of the Akt/mammalian target of rapamycin (mTOR) pathway has been implicated in mechanisms related to neoplastic transformation in renal cell cancer (RCC) through enhancement of cell proliferation and survival and mTOR activation has been reported to occur due to phosphorylation of mTOR. To further determine the relevance of mTOR expression and activation and to analyze their putative role as a biomarker for systemic treatment in metastatic RCC, we investigated the expression of mTOR and phospho(p)-mTOR in primary RCC and metastases and correlated levels with pathological variables and clinical outcome.

Methods: Tissue microarrays (TMA) from paraffin-embedded tissue from 342 patients with primary clear cell renal cell carcinoma and 90 patients undergoing surgical resection for metastases were immunohistochemically stained for mTOR and p-mTOR and expression was quantified with immunoreactivity scores.

Kidney transplantation in patients with previous renal cancer: a critical appraisal of current evidence and guidelines.

J Nephrol 2018 Oct 16. Epub 2018 Oct 16.

Medical Oncology, I.R.C.C.S. San Matteo University Hospital Foundation, Pavia, Italy.

Due to the increasing occurrence of renal cell carcinoma (RCC) in the general population and the high prevalence of chronic kidney disease among cancer patients, many people with a previous RCC may eventually require renal replacement therapy including kidney transplantation. They should accordingly be evaluated to assess their life expectancy and the risk that the chronic immunosuppressive therapy needed after grafting might impair their long-term outcome. Current guidelines on listing patients for renal transplantation suggest that no delay is required for subjects with small or incidentally discovered RCC, while the recommendations for patients who have been treated for a symptomatic RCC or for those with large or invasive tumours are conflicting.

Department of Pathology, Sun Yat-sen University Cancer Center, Guangzhou, 510060, People's Republic of China,

Purpose: The aim of this study was to investigate the degree of infiltration of CD8+ tumor-infiltrating lymphocytes (TILs) including high and low density in lung sarcomatoid carcinoma (LSC) and their clinicopathological significance.

Patients And Methods: The density of CD8+ TILs in paraffin-embedded tissue sections from 100 LSC patients was detected by immunohistochemical staining, and the relationship of CD8+ TILs with clinicopathological features and prognosis was analyzed.

Results: The chi-squared test showed that the degree of infiltration of CD8+ TILs was significantly correlated with the clinicopathological stage and T stage of LSC (<0. Read More

Highlights of the 14th international mesothelioma interest group meeting: Pathologic separation of benign from malignant mesothelial proliferations and histologic/molecular analysis of malignant mesothelioma subtypes.

Lung Cancer 2018 Oct 30;124:95-101. Epub 2018 Jul 30.

Centre National Référent MESOPATHm Centre Leon Berard, Lyon, France.

Objectives: The separation of benign from malignant mesothelial proliferations and exact subclassification of mesothelioma subtypes is crucial to determining patient care and prognosis but morphologically can be very difficult.

Methods: This session of the 2018 IMIG meeting addressed these problems.

Results: A new immunohistochemical marker, methylthioadenosine phosphorylase, was shown to correlate well with CDKN2A FISH and is cheaper and faster to run. Read More

Rare isolated synchronous splenic metastasis in a patient with type II papillary renal cell carcinoma.

AME Case Rep 2018 14;2. Epub 2018 Mar 14.

Department of Urology, Tan Tock Seng Hospital, Singapore.

Metastatic disease is common in renal cell carcinoma (RCC), with a third of cases being synchronous. RCC is known to metastasize to any organ in the body; however, isolated splenic metastasis is extremely rare. We report a case of synchronous splenic metastasis from type II papillary RCC with 80% sarcomatoid change. Read More

An anaplastic lymphoma kinase () fusion oncogene positive metastatic sarcomatoid carcinoma of the lung with good response to crizotinib.

AME Case Rep 2018 24;2. Epub 2018 Jan 24.

University of Tartu, Tartu 50090, Estonia.

Primary sarcomatoid carcinoma (SC) of the lung is a rare tumor that accounts for less than 1% of all lung cancers and compared to other non-small cell lung cancers (NSCLC) they appear more aggressive with poorer prognosis and response to treatment. Carcinosarcoma is one of the subtypes of SC. We report a case of carcinosarcoma with fusion gene in a 50-year-old male patient with a good response to therapy with crizotinib. Read More

Apatinib-based targeted therapy against pulmonary sarcomatoid carcinoma: a case report and literature review.

Oncotarget 2018 Sep 14;9(72):33734-33738. Epub 2018 Sep 14.

Department of Pathology, Affiliated Quanzhou First Hospital of Fujian Medical University, Quanzhou 362000, China.

Sarcomatoid carcinoma is a rare malignancy characterized by a combination of epithelial and sarcoma or sarcoma-like components. In this study, we reported one case of pulmonary sarcomatoid carcinoma and evaluated the safety and efficacy of apatinib, a tyrosine kinase inhibitor selectively targeting vascular endothelial growth factor receptor 2, in treating this disease. The tumor mass was detected in the left lung of a 75-year-old man and showed positive immunostaining for cytokeratin (CK) 7, CK8, smooth muscle actin, CD31, and CD34. Read More

What's new in mesothelioma.

Pathologica 2018 Mar;110(1):12-28

Department of Oncology, San Luigi Hospital, University of Turin, Orbassano, Italy.

Malignant pleural mesothelioma is a neoplasm characterized by a very poor prognosis and medico-legal implications. Diagnosis, prognosis and therapy are often challenging and include several issues. Cytological diagnosis is frequently the first step of the diagnostic process, and although its sensitivity may be somewhat lower, diagnostic criteria should be taken into account. Read More

Age Limit and Radiotherapy Option for Sarcomatoid Carcinoma of the Larynx: A Case Report with Literature Review.

Cureus 2018 Jul 22;10(7):e3023. Epub 2018 Jul 22.

Internal Medicine, Icahn School of Medicine at Mount Sinai/Queens Hospital Center, New York, USA.

Sarcomatoid carcinomas, also known as spindle cell carcinomas (SPCCs), are rare carcinomas, predominantly developing in the lung. They have lots of features of sarcoma in their histological features. The standard laryngeal carcinoma classification is based on tumor size, lymph node affection, and metastasis (TNM), it is the classification scheme of the American Joint Committee on Cancer Staging (AJCC), and it is used in the same way for stage spindle cell carcinoma (SPCC).
