Original Title: PET-TC en pacientes con diagnóstico de cáncer de cabeza y cuello
Authors' recommendations: CONCLUSIONS Moderate-quality evidence shows that the use of PET-CT for head and neck cancer diagnosis and staging presents adequate sensitivity and specificity with similar values to those of conventional imaging, such as CT scan or magnetic resonance imaging. Moderate-quality evidence shows that its use for primary tumor location in those cases where its origin is unknown, after performing conventional studies, presents adequate sensitivity and specificity, allowing a higher detection rate. In patients with metastatic cervical lymph nodes, who completed chemotherapy and radiotherapy, high-quality evidence shows that its use presents an adequate correlation with absence of disease, which would allow reducing the rate of cervical lymph node dissection. Finally, when it is used as the only follow-up imaging method, moderate-quality evidence shows an adequate sensitivity and specificity, showing higher specificity when it is performed twelve months after the end of treatment with chemo- radiotherapy. The clinical practice guidelines surveyed recommend its use for the staging of cervical lymph nodes and distant metastasis in those patients with stage III-IV where conventional images are equivocal or where treatment may be significantly modified. It is also recommended when the primary tumor site is unknown after performing conventional studies and rhinolaryngoscopy. It is recommended for staging and assessment of recurrence in patients with nasopharyngeal cancer if the conventional images are equivocal. These recommendations are covered by the health sponsors of the high-income countries surveyed. No economic assessments have been found in Argentina.
