MicroRNA expression profiling with a Droplet Digital PCR assay enables molecular diagnosis and prognosis of cancers of unknown primary (CUPs).

Mol Oncol 2021 Jun 2. Epub 2021 Jun 2.

Department of Experimental, Diagnostic and Specialty Medicine (DIMES), University of Bologna, Bologna, Italy.

Metastasis is responsible for the majority of cancer-related deaths. Particularly challenging is the management of metastatic cancer of unknown primary site (CUP), whose tissue of origin (TOO) remains undetermined even after extensive investigations and whose therapy is rather unspecific and poorly effective. Molecular approaches to identify the most probable TOO of CUPs can overcome some of these issues. Read More

Evaluating DNA Methylation, Gene Expression, Somatic Mutation, and Their Combinations in Inferring Tumor Tissue-of-Origin.

Front Cell Dev Biol 2021 3;9:619330. Epub 2021 May 3.

Academician Workstation, Changsha Medical University, Changsha, China.

Carcinoma of unknown primary (CUP) is a type of metastatic cancer, the primary tumor site of which cannot be identified. CUP occupies approximately 5% of cancer incidences in the United States with usually unfavorable prognosis, making it a big threat to public health. Traditional methods to identify the tissue-of-origin (TOO) of CUP like immunohistochemistry can only deal with around 20% CUP patients. Read More

AI-based pathology predicts origins for cancers of unknown primary.

Nature 2021 Jun 5;594(7861):106-110. Epub 2021 May 5.

Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Cancer of unknown primary (CUP) origin is an enigmatic group of diagnoses in which the primary anatomical site of tumour origin cannot be determined. This poses a considerable challenge, as modern therapeutics are predominantly specific to the primary tumour. Recent research has focused on using genomics and transcriptomics to identify the origin of a tumour. Read More

Department of Pathology, Cancer Institute, Imam Khomeini Hospital Complex, Tehran University of Medical Sciences, Iran.

Germ cell teratomas belong to non-seminomatous germ cell tumors and account for 95% of malignant testicular tumors. Regarding the current World Health Organization (WHO) criteria, testicular teratomas are divided into prepubertal and post-pubertal subtypes based on patients' age. The term "burned-out testicular tumor" is a very rare condition referring to a regressed testicular tumor which presents with its metastases without any clinical finding in the testicle. Read More

Non-Small Cell Carcinoma-Not Otherwise Specified on Cytology Specimens in Patients with Solitary Pulmonary Lesion: Primary Lung Cancer or Metastatic Cancer?

J Cytol 2021 Jan-Mar;38(1):8-13. Epub 2021 Jan 8.

Department of Pathology, Dong-A University College of Medicine, Busan, Korea.

Context: Subtyping of solitary pulmonary lesion (SPL) in small amount of cytology specimen using a limited panel of immunohistochemistry (IHC) markers is very important to the correct choice of treatment. This study was performed to categorize non-small cell carcinoma-not otherwise specified (NSCC-NOS) on cytology in patients with SPL, especially with regard to the incidence of metastatic cancer.

Materials And Methods: We reviewed 91 cases, in which a precise morphology-based, lineage-specific IHC-aided subtyping was not possible, that qualified as NSCC-NOS on cytology. Read More

Cancer of Unknown Primary in the Molecular Era.

Trends Cancer 2021 May 28;7(5):465-477. Epub 2021 Jan 28.

Center for Personalized Cancer Therapy and Division of Hematology and Oncology, Department of Medicine, UC San Diego Moores Cancer Center, La Jolla, CA, USA.

Cancer of unknown primary (CUP) is a rare malignancy that presents with metastatic disease and no identifiable site of origin. Most patients have unfavorable features and attempts to treat based on tissue-of-origin identification have not yielded a survival advantage compared with empiric chemotherapy. Next-generation sequencing has revealed genomic alterations that can be targeted in selected cases, suggesting that CUP represents a unique malignancy in which the genomic aberrations may be integral to the diagnosis.

A receptor-antibody hybrid hampering MET-driven metastatic spread.

J Exp Clin Cancer Res 2021 Jan 14;40(1):32. Epub 2021 Jan 14.

Candiolo Cancer Institute, FPO-IRCCS, Strada Provinciale 142, 10060, Candiolo, TO, Italy.

Background: The receptor encoded by the MET oncogene and its ligand Hepatocyte Growth Factor (HGF) are at the core of the invasive-metastatic behavior. In a number of instances genetic alterations result in ligand-independent onset of malignancy (MET addiction). More frequently, ligand stimulation of wild-type MET contributes to progression toward metastasis (MET expedience). Read More

Machine Learning Models to Predict Primary Sites of Metastatic Cervical Carcinoma From Unknown Primary.

Front Genet 2020 21;11:614823. Epub 2020 Dec 21.

Department of Thoracic Surgery, Nanfang Hospital, Southern Medical University, Guangzhou, China.

Metastatic cervical carcinoma from unknown primary (MCCUP) accounts for 1-4% of all head and neck tumors, and identifying the primary site in MCCUP is challenging. The most common histopathological type of MCCUP is squamous cell carcinoma (SCC), and it remains difficult to identify the primary site pathologically. Therefore, it seems necessary and urgent to develop novel and effective methods to determine the primary site in MCCUP. Read More

Melanoma of unknown primary: New perspectives for an old story.

Crit Rev Oncol Hematol 2021 Feb 28;158:103208. Epub 2020 Dec 28.

Medical School, University of Ioannina, Stavros Niarchou Avenue, 45110 Ioannina, Greece.

Melanoma of unknown primary site (MUP) comprises 3-4 % of all melanomas. It mostly presents in lymph nodes (LNs), followed by subcutaneous sites, and visceral organs; nevertheless, there is a trend of increase in the relative incidence of visceral counterpart in recent years. Spontaneous regression of the primary lesion is a well-established theory, based on the evidence that melanoma can undergo regression at the primary site. Read More

Circulating tumor cell characterization of lung cancer brain metastases in the cerebrospinal fluid through single-cell transcriptome analysis.

Clin Transl Med 2020 Dec;10(8):e246

Department of Clinical Laboratory, Huashan Hospital, Fudan University, Shanghai, China.

Background: Brain metastases explain the majority of mortality associated with lung cancer, which is the leading cause of cancer death. Cytology analysis of the cerebrospinal fluid (CSF) remains the diagnostic gold standard, however, the circulating tumor cells (CTCs) in CSF (CSF-CTCs) are not well defined at the molecular and transcriptome levels.

Methods: We established an effective CSF-CTCs collection procedure and isolated individual CSF cells from five lung adenocarcinoma leptomeningeal metastases (LUAD-LM) patients and three controls. Read More
