Objective:To investigate surgical treatment of carotid artery diseases in neck tumor surgery. Methods:A retrospective analysis of the clinical data on carotid artery treatment was conducted in the five cases of neck tumor surgeries treated at Department of Surgical Oncology, the First Peoples Hospital of Lanzhou from March 2010 to May 2020. Surgical methods, including carotid artery resection and ligation, tumor-involved artery resection and vascular reconstruction, and tumor peeling and carotid rupture repairing were used, respectively. Results:Five cases were successfully operated on. One case of carotid artery ligation was followed by intermittent dizziness and decreased contra-lateral limb strength after the surgery. The remaining patients exhibited no neurological complications. A patient with cervical low-grade myofibroblastoma developed into lung metastases 8 months after the surgery. Another patient with cervical lymph node metastases in papillary thyroid cancer developed into lung metastases 24 months after the surgery. Conclusion:Currently, surgical methods for clinical treatment of diseased carotid arteries include carotid artery resection and ligation, simple tumor peeling, tumor invasion artery resection and vascular reconstruction, and interventional therapy. Each surgical method has its own advantages and disadvantages. Therefore, the choice of treatment depends on the patient's specific conditions, physician's clinical experience, and the equipment available.

Report a case of cervical rhabdomyosarcoma. The illness development is rapid and the prognosis is poor. The clinical manifestations of dysfunction caused by local mass increases rapidly. The relevant imaging examination and laboratory examination can help establish a preliminary diagnosis, pathological examination of tumor can make a clear diagnosis.

The patient complained of a 20 days history of isolated mass in the right cervical region. The lesion was successfully eradicated by surgical removal. Histopathology established branchial cleft cyst carcinoma (BCCC) as the diagnosis. More attentions should be paid to the diagnosis of BCCC. Primary leisions were essential for the suspected cases. Importantly, only after excluding the metastatic squamous carcinoma in lymph nodes and other primary diseases, the diagnosis of BCCC would be established. Therapeutic strategies include complete local excision, radical neck dissection, and post-operative radiotherapy.

Human papillomavirus (HPV) is a major causative agent of head and neck squamous cell carcinomas (HNSCC). Over the past several decades, an increasing number of studies established the strong association of HPV with the invasion and metastasis of HNSCC. In the present study, we reviewed the gene mutations in HPV-associated HNSCC and the unique mechanism of E6- and E7-mediated carcinogenesis via interactions with an array of cellular elements. We further discussed the progress in the mechanisms of invasion and metastasis; these mechanisms include non-coding RNAs, deregulating cellular energetics, tumor microenvironment, cancer stem cells, angiogenesis, and lymphangiogenesis.
