Introduction. The increasing incidence of oropharyngeal squamous cell carcinoma observed globally in recent decades gave rise to research in this area. In 2005, human papillomavirus was proved to be an etiological factor of oropharyngeal squamous cell carcinoma. Currently, oropharyngeal squamous cell carcinoma associated with human papillomavirus is believed to have some unique characteristics. The analysis of oropharyngeal squamous cell carcinoma epidemiology appears to be highly relevant.Objective – to assess the incidence and prevalence of oropharyngeal squamous cell carcinoma associated with human papillomavirus in Russia on the example of a certain sample of patients.Materials and methods. We analyzed medical records of 199 oropharyngeal squamous cell carcinoma patients treated in N. N. Blokhin Russian Cancer Research Center between 2016 and 2021. We analyzed the frequency of tumors associated with human papillomavirus, age, sex, tumor spread and stage depending on р16 status.Results. More than half of the patients from our cohort (58.3 %) were р16‑positive. The peak incidence was observed in individuals aged 45 to 64 years (more than 60 % of cases). Males were twice as likely to have р16‑positive tumors than females. A total of 60.9 % of patients with р16‑positive tumors had stage I disease, whereas 51.2 % of patients with p16‑negative tumors had stage IV disease.Conclusion. The results obtained for a sample of Russian patients are comparable with the findings of foreign authors.

Background. Reconstruction of defects following surgery for head and neck cancer possess challenges for surgeons. The choice of the reconstruction option is determined by various factors, namely: the size and location of the defect, patients’ age, concomitant pathology, prognosis of the disease, and individual decisions of surgeons and patients. Microvascular surgery is a highly successful and relatively safe method for the reconstruction of large head and neck defects. However, the use of revascularized autografts is not possible in all categories of patients, and therefore the search for new reconstruction techniques is necessary to improve functional, aesthetic results and reduce trauma.Material and methods. The use of different types of facial artery mucous-muscular (FAMM) flaps for the reconstruction of oral cavity defects after tumor resection was analyzed. From June 2020 to march 2021, 7 patients with histologically verified t2–4N0–1 oral cancer were treated at Blokhin National medical Research center of oncology (Moscow). The patients underwent tumor resection with one-stage reconstruction using different types of FAMM flaps. All patients underwent adjuvant radiation therapy.Results. When cutting out the flap, an additional skin incision was not performed, the defect in the oral cavity was replaced by tissues of the same composition while preserving the small salivary glands, respectively, there was no hair growth and a defect in the donor bed. None of the cases had malnutrition of the flap.Conclusion. Good functional and cosmetic results in patients who underwent FAMM flap reconstruction may set a new standard in the replacement of small-to medium-size soft tissue defects in the oral cavity

Сочетание онкологической и кардиологической патологии является сложной клинической задачей и требует участия в лечении пациента мультидисциплинарной команды врачей. В данной статье представлен опыт успешного лечения пациента с серьезной сочетанной патологией.

Oral mucositis is one of the most common effects of chemoradiotherapy in patients with oropharyngeal cancer. The development of oral mucositis is the main cause of interruption of antitumor therapy, which significantly affects the results of treatment of the main disease. Despite the fact that the disease is well studied in the literature, today there is no universal treatment and prevention protocol. The aim of this review is to analyze scientific publications devoted to the problems of etiology, pathogenesis, clinic, diagnosis, treatment and prevention of oral mucositis.
