The authors report a very unusual occurrence of a metastatic squamous carcinoma to thyroid gland from a treated squamous cell carcinoma cervix 12 years before with no recurrence at the primary site. The case also has an additional complexity of rapid progression of the metastatic thyroid carcinoma to wide spread dissemination to lungs and bones while on concurrent chemo radio therapy confirming the aggressiveness of the entity.

Purpose: Immune checkpoint inhibitors (ICIs) are now first-line therapy for most patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), and cetuximab is most often used as subsequent therapy. However, data describing cetuximab efficacy in the post-ICI setting are limited.
Methods: We performed a single-institution retrospective analysis of patients with R/M HNSCC treated with cetuximab, either as monotherapy or in combination with chemotherapy, after receiving an ICI.
Background: For patients with head and neck squamous cell carcinoma (HNSCC), failure of definitive radiation combined with cisplatin nearly universally results in death. Although hyperactivation of the Nrf2 pathway can drive radiation and cisplatin resistance along with suppressed anti-tumor immunity, treatment-refractory HNSCC tumors may retain sensitivity to targeted agents secondary to synergistic lethality with other oncogenic drivers (e.g.

Mechanotransduction studies have extensively probed the mechanisms by which ECM stiffness regulates intracellular communication. However, the influence of stiffness on intercellular communication aiding tumor progression in three-dimensional microenvironments remains unknown.

Background: Nivolumab paved a new way in the treatment of patients with recurrent or metastatic (RM) head and neck squamous cell carcinoma (RM-HNSCC). However, the limited rates of long-term survivors (< 20%) demand a robust prognostic biomarker. This nationwide multi-centric prospective study aimed to identify a plasma exosome (PEX) mRNA signature, which serves as a companion diagnostic of nivolumab and provides a biological clue to develop effective therapies for a majority of non-survivors.

Background: The presence of level IV/V metastasis is a significant prognostic factor for patients with oral and oropharyngeal cancer, while level IV lymphadenopathy defines the N3 stage in nasopharyngeal carcinoma. However, the current staging system for hypopharyngeal squamous cell carcinoma (HPSCC) does not consider the location of involved nodes.
Objectives: To evaluate the risk factors and prognostic impact of level IV/V metastasis in patients with HPSCC.
