Intraoperative delineation of p16+ oropharyngeal carcinoma of unknown primary origin with fluorescence lifetime imaging: Preliminary report.

Head Neck 2022 May 5. Epub 2022 May 5.

Department of Otolaryngology - Head & Neck Surgery, University of California, Davis, Davis, California, USA.

Background: This study evaluated whether fluorescence lifetime imaging (FLIm), coupled with standard diagnostic workups, could enhance primary lesion detection in patients with p16+ head and neck squamous cell carcinoma of the unknown primary (HNSCCUP).

Methods: FLIm was integrated into transoral robotic surgery to acquire optical data on six HNSCCUP patients' oropharyngeal tissues. An additional 55-patient FLIm dataset, comprising conventional primary tumors, trained a machine learning classifier; the output predicted the presence and location of HNSCCUP for the six patients.

Unusual presentation of HPV-positive squamous cell carcinoma of the nasolacrimal duct as carcinoma of unknown primary.

Am J Otolaryngol 2022 May-Jun;43(3):103457. Epub 2022 Apr 6.

Division of Otolaryngology-Head and Neck Surgery, Brigham and Women's Hospital, Boston, MA, USA; Department of Otolaryngology, Harvard Medical School, Boston, MA, USA; Center for Head and Neck Oncology, Dana-Farber Cancer Institute, Boston, MA, USA. Electronic address:

Most human papillomavirus (HPV)-positive carcinomas of unknown primary (CUP) in the cervical lymph nodes are ultimately found to arise from the oropharynx, which has by far the highest prevalence of HPV-positivity among head and neck tumors. However, HPV is also detected in a subset of tumors from other sites. In this case report, we describe the first reported instance of a lacrimal sac carcinoma presenting as an HPV-positive CUP.

The Narrow Band Imaging as an essential complement to White Light Endoscopy in Recurrent Respiratory Papillomatosis diagnostics and follow-up process.

Otolaryngol Pol 2021 Oct;76(1):1-5

Department of Otolaryngology, Head and Neck Surgery, Poznan University of Medical Sciences, Poland.

The aim of the study is to discuss the role of NBI imaging in upper respiratory papillomatosis (RRP). In the available literature on the subject, as of 2009, there have been 117 publications on NBI imaging focusing on the diagnosis of the upper respiratory and digestive tract, especially the larynx. They discuss the following diagnostic and therapeutic problems: identifying an abnormal vascular pattern within the mucosa, differentiating benign and malignant lesions, assessing the nature of lesions under the leukoplakia plaque, pre-operative definition of laryngeal cancer margins, supporting laser procedures to obtain safe margins, postoperative monitoring after cancer treatment, detecting second simultaneous and metachronic neoplasms and primary tumors in the case of metastases from an unknown primary site.

Clinical Validity of Plasma-Based Genotyping for Microsatellite Instability Assessment in Advanced GI Cancers: SCRUM-Japan GOZILA Substudy.

JCO Precis Oncol 2022 02;6:e2100383

Clinical Research Support Office, National Cancer Center Hospital East, Kashiwa, Japan.

Purpose: Circulating tumor DNA (ctDNA) genotyping may guide targeted therapy for patients with advanced GI cancers. However, no studies have validated ctDNA genotyping for microsatellite instability (MSI) assessment in comparison with a tissue-based standard.

Patients And Methods: The performance of plasma-based MSI assessment using Guardant360, a next-generation sequencing-based ctDNA assay, was compared with that of tissue-based MSI assessment using a validated polymerase chain reaction-based method in patients with advanced GI cancers enrolled in GOZILA study, a nationwide ctDNA profiling study.

Recognizing Tumor Origin for Lymphoid Tumor of Unknown Primary Total-Body PET/CT Scan-Case Report.

Front Oncol 2022 3;12:766490. Epub 2022 Feb 3.

Science and Technology Innovation Center, Shandong First Medical University & Shandong Academy of Medical Sciences, Jinan, China.

Localizing the site of tumor origin for patients with lymphoid tumor is fairly difficult before the definitive detection of the primary tumor, which causes redundant imaging examinations and medical costs. To circumvent this obstacle, the emergence of the world's first total-body positron emission tomography/computed tomography (PET/CT) provides a transformative platform for simultaneously static and dynamic human molecular imaging. Here, we reported a case of lymph node metastasis from an unknown primary tumor, and the primary tumor was detected with the aid of the total-body PET/CT scanner. Read More

Machine learning models predict the primary sites of head and neck squamous cell carcinoma metastases based on DNA methylation.

J Pathol 2022 04 20;256(4):378-387. Epub 2022 Jan 20.

Charité - Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, Institute of Pathology, Berlin, Germany.

In head and neck squamous cell cancers (HNSCs) that present as metastases with an unknown primary (HNSC-CUPs), the identification of a primary tumor improves therapy options and increases patient survival. However, the currently available diagnostic methods are laborious and do not offer a sufficient detection rate. Predictive machine learning models based on DNA methylation profiles have recently emerged as a promising technique for tumor classification. Read More

Department of Otorhinolaryngology, Head and Neck Surgery & Audiology, Rigshospitalet, Copenhagen University Hospital, 2100 Copenhagen, Denmark.

Squamous cell carcinoma of unknown primary (SCCUP) is a challenging diagnostic subgroup of oropharyngeal squamous cell carcinoma (OPSCC). The incidence of SCCUP is increasing in parallel with the well-documented increase in OPSCC and is likewise driven by the increase in human papillomavirus (HPV). The SCCUP patient often presents with a cystic lymph node metastasis and undergoes an aggressive diagnostic and treatment program. Read More

Sparing the Larynx and Hypopharynx With Radiation Therapy for Squamous Cell Carcinoma of Unknown Primary Site and Predominant Adenopathy in Level IIA.

Pract Radiat Oncol 2021 Sep-Oct;11(5):366-373. Epub 2021 Jun 24.

Departments of Radiation Oncology. Electronic address:

Purpose: There is controversy about the need to target the mucosa of the larynx and hypopharynx during radiation therapy (RT) for squamous cell carcinoma of an unknown primary site (SCCA-UP). By 1997, the policy in our department was to target only the oropharynx and nasopharynx in patients with SCCA-UP metastatic to the level II cervical nodes. The purpose of this study was to report the rate of cancer recurrence in the larynx or hypopharynx using an approach that excluded these areas from the RT target volumes. Read More

Front Oncol 2021 7;11:682088. Epub 2021 May 7.

Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Leipzig, Leipzig, Germany.

Background: About five to 10% of cancers in the head and neck region are neck squamous cell carcinoma of unknown primary (NSCCUP). Their diagnosis and treatment are challenging given the risk of missing occult tumors and potential relapse.

Cancer incidence and cancer death in relation to tobacco smoking in a population-based Australian cohort study.

Int J Cancer 2021 09 31;149(5):1076-1088. Epub 2021 May 31.

The Daffodil Centre, The University of Sydney, A Joint Venture With Cancer Council NSW, Sydney, Australia.

Tobacco smoke is a known carcinogen, but the magnitude of smoking-related cancer risk depends on country-specific, generational smoking patterns. We quantified cancer risk in relation to smoking in a population-based cohort, the 45 and Up Study (2006-2009) in New South Wales, Australia. Cox proportional hazards regressions estimated adjusted hazard ratios (HR) by self-reported smoking history at baseline (2006-2009) for incident, primary cancers via linkage to cancer registry data to 2013 and cancer death data to 2015.

Diagnostic approaches to carcinoma of unknown primary of the head and neck.

Eur J Cancer Care (Engl) 2021 Nov 1;30(6):e13459. Epub 2021 May 1.

Department of Otolaryngology-Head and Neck Surgery, Vanderbilt University Medical Center, Nashville, Tennessee, USA.

Squamous cell carcinoma in cervical lymph nodes arising from an undetected primary tumour, termed carcinoma of unknown primary (SCCUP), is a well-recognized clinical presentation within head and neck oncology. SCCUP is a common presentation for patients with human papillomavirus-mediated oropharyngeal cancer (HPV + OPSCC), as patients with HPV + OPSCC often present with smaller primary tumours and early nodal metastasis. Meticulous work-up of the SCCUP patient is central to the management of these patients as identification of the primary site improves overall survival and allows for definitive oncologic resection or more focused radiation when indicated.
