Locoregional extension patterns of nasopharyngeal carcinoma and suggestions for clinical target volume delineation
TLDR
The locoregional extension patterns of nasopharyngeal carcinoma (NPC) are defined and individualized CTV delineation for NPC may be feasible.
Locoregional Extension Patterns of Nasopharyngeal Carcinoma Detected by FDG PET/MR
TLDR
For NPCs, primary disease and regional lymph node spread follow an orderly pattern, and a skip pattern of lymph node metastasis was unusual, and involved level radiotherapy might be feasible for cervical lymph node levels below the caudal border of cricoid cartilage and level VIIb.
Characteristics of locoregional extension of unilateral nasopharyngeal carcinoma and suggestions for clinical target volume delineation
TLDR
Contralateral parapharyngeal space and skull base foramina had a very low probability of invasion, and routine prophylactic radiation may not be necessary.
Patterns of local failures and suggestions for reduction of clinical target volume for nasopharyngeal carcinoma patients without cervical lymph node metastasis
TLDR
IMRT with elective neck irradiation provides excellent local control for NPC patients without cervical lymph node metastasis, and suggestions for reduction of target volume during IMRT treatment for NPCs are proposed.
Analysis of Clinical Target Volume Delineation in Local-regional Failure of Nasopharyngeal Carcinoma after Intensity-modulated Radiotherapy
TLDR
It is suggested that IMRT provide a good local control for patients with NPC, and the in-field failure is the main mode, and a wide range of CTV cannot prevent the local recurrence, narrowing the CTV to protect the adjacent organs should be taken into consideration.
MR Imaging Criteria for the Detection of Nasopharyngeal Carcinoma: Discrimination of Early-Stage Primary Tumors from Benign Hyperplasia
TLDR
MR imaging features can help distinguish stage T1 nasopharyngeal carcinoma from benign hyperplasia in most cases, and size asymmetry was the most accurate criterion for nasoph throat carcinoma detection.
Impact of primary tumor volume and location on the prognosis of patients with locally recurrent nasopharyngeal carcinoma
TLDR
A new staging system has been proposed, with T3 tumors being down-staged to T2 and with the tumor volume being incorporated into the staging, which may lead to an improved evaluation of these tumors.
The efficacy and toxicity of individualized intensity-modulated radiotherapy based on the tumor extension patterns of nasopharyngeal carcinoma
TLDR
IMRT using individualized CTVs provided high rates of local and regional control and a favorable toxicity profile in NPC, and deserves optimization to define more precise individualizedCTVs.

Nasopharyngeal carcinoma: CT evaluation of patterns of tumor spread.
TLDR
The extent of paranasopharyngeal extension so evaluated was correlated with other attributes of tumor extent, namely, nasal or oropharyngeAL extension, which constitutes a T3-level tumor, and erosion of the base of the skull or orbit, which constituted a T4- level tumor.

Paranasopharyngeal tumour extension (PTE) from nasopharyngeal carcinoma (NPC) is staged in its own subgroup in the American Joint Committee on Cancer classification. Most large clinical trials use
Nasopharyngeal carcinoma with intracranial spread: CT and MR characteristics.
TLDR
It is believed that NPC most commonly spreads intracranially via the FL or by direct erosion, which explains why with CT evidence of cavernous sinus involvement there may be no skull base erosion.

Nasopharyngeal carcinoma: MRI and CT assessment
TLDR
It is believed that MRI allows more accurate evaluation of the extent of NPC than CT and should be the primary mode of investigation.
The value of MRI in the diagnosis and staging of nasopharynx tumors.
TLDR
MR performs better than CT in follow-up of irradiated patients and allows differentiation between tumor recurrence and postradiation fibrosis, and staging of lymph node metastases is as accurate with MR as with CT, but MR evaluation requires more experience.

Imaging features and clinical significance of perineural spread or extension of head and neck tumors.
TLDR
It is imperative that the radiologist be familiar with both normal cranial nerve anatomy and the radiologic appearance and assessment of perineural tumor extension, because patients with radiologically or pathologically provedperineural spread may have normal nerve function at clinical examination.
