Possible applications include the detection of an occult primary tumor metastatic to cervical nodes, locoregional staging, assessment of treatment response to external beam irradiation (also in combination with chemotherapy), and surveillance for recurrence. The success of high-precision irradiation techniques such as intensity-modulated radiation therapy (IMRT) appears to be improved by delineating the tumor volume using PET/CT. Read More

[The progress on diagnosis and treatment of larynx cancer].

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 2019 Nov;33(11):1017-1021

Laryngeal cancer remains one of the most common tumors of head and neck. While significant advancements have been made over the last several decades, diagnosis and treatment of laryngeal cancer presents an unique challenge given its complexity. It is essential to perform a thorough preoperative assessment by the dedicated multidisciplinary team(MDT), including confirmed diagnosis, accurate staging, surgical selection, rehabilitation and reconstruction, supportive care and postoperative follow-up.

Human papilloma virus related squamous cell carcinomas of the head and neck: diagnosis, clinical implications and detection of HPV.

Pathology 2020 Feb 27;52(2):179-191. Epub 2019 Dec 27.

Department of Anatomical Pathology, ACT Pathology, The Canberra Hospital, Woden, ACT, Australia; Australian National University Medical School, College of Health and Medicine, Canberra, ACT, Australia. Electronic address:

High-risk human papillomavirus (HPV) positive squamous cell carcinoma (SCC) of the head and neck is reported most commonly in the oropharynx but can also uncommonly be found in other sites such as the anterior oral cavity and sinonasal tract. While HPV positive oropharyngeal squamous cell carcinoma (HPV-OPSCC) has been shown to have a more favourable prognosis than conventional smoking- and alcohol-related anterior oral cavity squamous cell carcinoma (OSCC), HPV positive SCC arising elsewhere in the head and neck region does not carry the same favourable prognosis. HPV-OPSCC often tends to present with large cystic metastases in the cervical lymph nodes, with a clinically and radiologically occult primary. Read More

Merkel Cell Carcinoma of the Head and Neck Compared to Other Anatomical Sites in a Real-World Setting: Importance of Surgical Therapy for Facial Tumors.

Facial Plast Surg 2020 Jun 30;36(3):249-254. Epub 2019 Dec 30.

Department of Dermatology, University Hospital Erlangen, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Germany.

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin tumor with a high propensity for nodal involvement, local recurrence, and distant metastases. Up to 50% of MCC arises on head and neck (HN), which may impede oncological treatment due to insufficiently wide excisions and a lower rate of sentinel lymph node detection due to more complicated lymph drainage. Several studies have compared the clinical outcome of HN-MCC with those of non-head and neck (NHN) MCC yielding inconsistent results. Read More

Molecular phenotyping and image-guided surgical treatment of melanoma using spectrally distinct ultrasmall core-shell silica nanoparticles.

Sci Adv 2019 12 4;5(12):eaax5208. Epub 2019 Dec 4.

Department of Radiology, Sloan Kettering Institute for Cancer Research, New York, NY 10065, USA.

Accurate detection and quantification of metastases in regional lymph nodes remain a vital prognostic predictor for cancer staging and clinical outcomes. As intratumoral heterogeneity poses a major hurdle to effective treatment planning, more reliable image-guided, cancer-targeted optical multiplexing tools are critically needed in the operative suite. For sentinel lymph node mapping indications, accurately interrogating distinct molecular signatures on cancer cells in vivo with differential levels of sensitivity and specificity remains largely unexplored.

Distant Intramuscular Metastases of Head and Neck Squamous Cell Carcinoma.

Ann Plast Surg 2020 01;84(1S Suppl 1):S11-S16

From the Division of Plastic Surgery, Department of Surgery, Chi Mei Medical Center, Tainan, Taiwan.

Objectives: Metastasis of head and neck squamous cell carcinoma (HNSCC) usually occurs regionally in the neck lymph nodes, but also more infrequently at distant organs (eg, the lungs, bone, and liver). Intramuscular metastasis (IMM) has rarely been described. Therefore, we aimed to identify this disease characteristic and to evaluate available medical management options. Read More

Sentinel lymph node biopsy in medullary thyroid microcarcinomas.

Endocr J 2020 Mar 3;67(3):295-304. Epub 2019 Dec 3.

Surgical Oncology Clinic, Institute for Oncology and Radiology of Serbia, Belgrade, 11000, Serbia.

The aim of this prospective study was to analyze accuracy of sentinel lymph node biopsy with methylene blue dye for intraoperative detection of lateral metastases in clinically N0M0 medullary microcarcinomas with calcitonin <1,000 pg/mL and selection of true-positive patients for one-time therapeutic lateral dissection. In addition to total thyroidectomy and central neck dissection, all patients had bilateral sentinel biopsy of jugulo-carotid regions after methylene blue injection to decide upon necessity for lateral dissection. If sentinels were benign on frozen section, additional non-sentinels were extirpated, with no further lateral dissection. Read More

F-FDG PET/CT versus CT/MR imaging for detection of neck lymph node metastasis in palpably node-negative oral cavity cancer.

J Cancer Res Clin Oncol 2020 Jan 12;146(1):237-244. Epub 2019 Oct 12.

Department of Otolaryngology, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul, 05505, Republic of Korea.

Purpose: Subclinical lymph node (LN) metastasis is associated with poor survival outcome in oral cavity squamous cell carcinoma (OCC), which alleges elective neck LN dissection. Preoperative detection of metastatic LNs may improve prognosis and proper management of OCC. We examined the clinical usefulness of fluorine 18-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/computed tomography (CT) for the detection of occult neck LN metastasis in OCC patients in comparison with conventional CT/magnetic resonance (MR) imaging.

Risk of post-operative, pre-radiotherapy contralateral neck recurrence in patients treated with surgery followed by adjuvant radiotherapy for human papilloma virus-associated tonsil cancer.

Br J Radiol 2019 Dec 15;92(1104):20190466. Epub 2019 Oct 15.

Department of Radiation Oncology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Objective: One approach to reduce treatment-related morbidity for human papilloma virus (HPV)-associated tonsil cancer is omitting radiotherapy to the contralateral neck. Pathologic risk factors for early contralateral neck disease, however, are poorly understood. We report on the risk contralateral neck failures from the time of pre-operative diagnostic imaging to time of planning for adjuvant radiation in a single institution series of HPV-associated tonsillar cancer patients undergoing surgery followed by radiotherapy (RT).

Preoperative Computed Tomography Changes Surgical Management for Clinically Low-Risk Well-Differentiated Thyroid Cancer.

Ann Surg Oncol 2019 Dec 3;26(13):4439-4444. Epub 2019 Oct 3.

Department of Surgery, University Health Network, 200 Elizabeth Street, Toronto, ON, M5G 2C4, Canada.

Background: In the current guidelines for differentiated thyroid cancer (DTC), computed tomography (CT) of the neck has a limited role. The authors hypothesized that adding CT to the workup of clinically low-risk DTC size 4 cm or smaller changes the surgical management for a portion of patients due to detection of clinically significant lymph node metastases not located by ultrasound of the neck.

Methods: A prospective cohort of DTC patients at an academic referral center between 2012 and 2016 was reviewed. Read More
