The incidence of rhinopharyngeal carcinoma is fewer than one person per 100,000 population but it is one of the most common types of cancer in Southern China. The mechanisms often implicated suggest an important role of genetic, ethnic and environmental factors. Lung metastases are the most frequent, accounting for 66% of distant metastases. Other metastatic sites include bone (22%) and liver (10%). We report a case with breast skin and axillary nodes involvement.

Introduction And Importance: Chordoma is an uncommon malignant tumor that originates from the remnants of the primitive notochord in the embryo. They account for 1 % of intracranial tumors and 4 % of primary bone tumors. It is a locally aggressive tumor with a low risk of metastasis.

Background: Radiotherapy with or without concurrent chemotherapy is a standard of care treatment for patients with head and neck squamous cell carcinoma (HNSCC). Upon completion, patients are referred for a post-treatment F-FDG PET/CT (Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography) scan to help guide ongoing management by assessing for the presence or absence of residual or recurrent disease and differentiating this from post-treatment inflammation. To improve objective reporting of response, we developed the Christie score.

Objective: Post-irradiation sinonasal mucosa disease (SMD) is observed in patients with nasopharyngeal carcinoma (NPC) treated with radiotherapy (RT), leading to a detrimental impact on quality of life. This study aimed to assess the incidence, severity, and regression of the post-irradiation SMD among patients with NPC treated with proton therapy.
Methods: NPC patients treated with proton therapy were retrospectively enrolled.

Importance: Nasopharyngeal carcinoma (NPC) is closely linked to microorganisms, especially intra-tumoral microbiota. However, the role of commensal microbiota in NPC remains underexplored, with implications for understanding disease mechanisms.
Objective: This study aims to analyze and compare the bacterial microbiota in the nasopharynx and middle meatus (MM) of individuals with NPC and those without NPC.
