Squamous Cell Carcinoma: PET/CT and PET/MRI of the Pre-Treatment and Post-Treatment Neck

Publication date: Available online 17 July 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Katie Suzanne Traylor, Nicholas Koontz, Kristine MosierAbstractThe incidence of head and neck cancer continues to rise annually, most commonly squamous cell carcinoma (SCCa). Advances in imaging techniques have improved diagnostic accuracy with important ramifications for initial staging and post-treatment surveillance. FDG-PET/CT and, more recently, FDG-PET/MRI have revolutionized the staging and surveillance of head &neck SCCa. We detail the diagnostic role of FDG-PET/CT and FDG-PET/MRI of SCCa at the different head and neck subsites, highlighting their role in identifying the primary tumor extent, regional nodal metastases, and distant metastatic disease in the pre-treatment and post-treatment setting, as well as implications for staging, treatment, and prognosis.

We report on a series of 6 patients with mediastinal metastasis from lung cancer in whom the endobronchial ultrasound (EBUS) showed that most of the lymph node tissue had “melted”, leading to the formation of a single, anechoic, avascular cavity. Besides the unique EBUS pattern, we describe the imaging and pathology findings of this unusual presentation of malignant mediastinal lymphadenopathy to facilitate its recognition.

Yansong Liang, Xuemin Di, Zezhou Liu, Jinxin Zhao, Zeyang Wang, Jing Zhao, Aixia Sui, Hongtao Zhang, Juan WangJournal of Cancer Research and Therapeutics 2018 14(7):1660-1664 The skin squamous cell carcinoma (SCC) is a kind of malignancy of keratinocytes. SCC was originated within the epidermis or relevant appendages, which commonly occurred on sunlight exposure sites, such as the head and neck. This case report described an 85-year-old female patient with skin SCC at the right frontal, accompanied with skin ulcer. This patient suffered from indications that were not suitable for surgical resection, including old age, Alz...

Conclusion: Collectively, our observations demonstrate the utility of PAI for temporal mapping of tumor hemodynamics and the value of PAI read-outs as surrogate measures of radiation response in HNSCC.

ConclusionsAlthough breast metastases are extremely rare, they should be considered in any patient with a history of cancer and confirmed by histology and immunohistochemistry because they are very difficult to distinguish from other primary breast tumors based only on clinical and radiological features. There are no standardized treatment guidelines for breast metastasis management. Surgery and radiotherapy can play a role in symptom palliation, but they do not have any relevant impact on survival, the prognosis being poor, with an estimated overall survival less than 1 year from diagnosis.

Rath Head and neck squamous cell carcinoma is an important cause of cancer morbidity worldwide and has been stratified into human papillomavirus-related and human papillomavirus-unrelated subgroups that affect prognosis and now staging. Conventional anatomical imaging methods are suboptimal for the detection of regional and distant metastases that are important prognosticators associated with poor outcomes.
