European Radiology: Prognostic value of MRI parapharyngeal subspace involvement in nasopharyngeal carcinoma

Nasopharyngeal carcinoma (NPC) is a kind having a local distribution characteristics of head and neck cancer, particularly in South East Asia especially area

Nasopharyngeal carcinoma (NPC) is a kind having a local distribution characteristics of head and neck cancer, particularly in South East Asia especially area

At this stage , at present the eighth edition of the American Joint Committee on Cancer / International Union Control Cancer (AJCC / UICC) staging system, T2 and T3 NPC number of patients and unbalanced, and survival curves there is overlap

In the past most of the studies, the parapharyngeal space sub-classified mostly according to the CT division

Recently, published in the E uropean a journal Radiology study by the MRI performed parapharyngeal sub-district division gap to assess PPSI prognosis and study of its patients in the current staging system AJCC / UICC NPC in value , as the NPC patients The formulation of personalized treatment plan provides a valuable reference basis .

In this study , 1224 nasopharyngeal carcinoma patients in two centers were retrospectively evaluated on MRI to clarify PPSI and divided into four invasion modes: mode A (only the posterior styloid space), mode B ( styloid process) Posterior space , CS extension), mode C ( posterior styloid space , anterior styloid space extension) and mode D (all gaps)
