BackgroundIntensity-modulated radiation therapy (IMRT) has represented a technical milestone that has facilitated the clinical implementation. The purpose of this study was to evaluate the prognostic value of maximum primary tumor diameter (MPTD) in patients with nasopharyngeal carcinoma (NPC) treated using IMRT.MethodsFive-hundred and sixty-six patients with non-metastatic, histologically-confirmed NPC were retrospectively reviewed. MPTD was measured using magnetic resonance imaging (MRI). All… 
Prognostic value of total tumor volume in patients with nasopharyngeal carcinoma treated with intensity-modulated radiotherapy
TLDR
TTV is an important prognosticator for treatment outcome and significantly improves the prognostic value of the current staging system for patients with NPC treated with IMRT, as revealed by ROC curve analysis curves.
The Value of Tumor Diameter in Predicting Prognosis of Nasopharyngeal Carcinoma Treated with Intensity-Modulated Radiotherapy
TLDR
Tumor diameter may be related to the extent of tumor invasion and can provide important information on prognosis and help to refine the predictive power of the current staging system for NPC.
Long-term Therapeutic Outcome and Prognostic Factors of Patients with Nasopharyngeal Carcinoma Receiving Intensity-modulated Radiotherapy: An Analysis of 608 Patients from Low-endemic Regions of China
TLDR
IMRT provides patients with newly-diagnosed non-metastatic NPC with satisfactory long-term survival, and both T stage and N stage are important prognostic factors for NPC patients.

TLDR
Tumor necrosis served as a predictor of treatment sensitivity and poor prognosis for patients with nasopharyngeal carcinoma treated using intensity-modulated radiation therapy and significantly improved the prognostic value of the current N classification criteria.
Survival and Toxicities of IMRT Based on the RTOG Protocols in Patients with Nasopharyngeal Carcinoma from the Endemic Regions of China
TLDR
The RTOG IMRT protocols are feasible for patients with NPC from the endemic regions of China, and T and N category were significant prognostic factors for OS, FFS, RRFS and DMFS.
Evaluation of tumor volume reduction of nasal carcinomas versus sarcomas in dogs treated with definitive fractionated megavoltage radiation: 15 cases (2010–2016)
TLDR
Within the study period carcinomas were more responsive in the reduction of volume than sarcomas with fractionated megavoltage radiation, which resulted in a mean reduction in tumor size for both carcinomas and sarcoma.

TLDR
GTV-P is an independent prognostic indicator for treatment outcome after IMRT, and significantly improves the prognostic validity of T classifications in NPC.
Prognostic significance of maximum primary tumor diameter in nasopharyngeal carcinoma
TLDR
The data suggest that MPTD is an independent prognostic factor in NPC, and incorporation of MPTD might lead to a further refinement of T staging, as well as in patients with a MPTD.
How does intensity-modulated radiotherapy versus conventional two-dimensional radiotherapy influence the treatment results in nasopharyngeal carcinoma patients?
TLDR
A greater improvement of treatment results with IMRT than with 2D-CRT was demonstrated primarily by achieving a higher local tumor control rate in NPC patients, especially in the early T stage patients.

TLDR
Determined CTV through GTV expansion to a minimally required margin, using GTV+margin (used in the authors' T4 patients)+the whole nasopharyngeal mucosa, especially for the patients with early T disease, might be feasible.

TLDR
IMRT for NPC yielded excellent survival outcomes, and distant metastasis was the most commonly seen failure pattern after treatment, and concurrent chemotherapy failed to improve survival rates for patients with advanced locoregional disease.
Clinical application of tumor volume in advanced nasopharyngeal carcinoma to predict outcome
TLDR
Large GTVprn was associated with a significantly poorer local control, lower distant metastasis-free rate, and poorer survival, but overall survival was better after ≧4 cycles of chemotherapy than after less than 4 cycles.
Does MRI-Detected Cranial Nerve Involvement Affect the Prognosis of Locally Advanced Nasopharyngeal Carcinoma Treated with Intensity Modulated Radiotherapy?
TLDR
In patients with clinical T3 disease, the presence of MRI-detected CNI is not sufficient evidence for defining T4 disease, and when treated with IMRT,MRI-detection CNI in patients with NPC does not appear to affect the prognosis.
Primary tumor regression speed after radiotherapy and its prognostic significance in nasopharyngeal carcinoma: a retrospective study
TLDR
PT regression speed at the end of RT was an independent prognostic factor of OS, FFS, and DMFS in NPC patients and immediate strengthening treatment may be provided to patients with poor tumor regression at theend of RT.
The additional value of chemotherapy to radiotherapy in locally advanced nasopharyngeal carcinoma: a meta-analysis of the published literature.
TLDR
Concomitant chemotherapy in addition to radiation is probably the most effective way to improve OS in NPC, according to the results of this meta-analysis.

TLDR
Intensity-modulated radiotherapy provides excellent locoregional control for NPC, and more effective systemic agents should be explored for patients presenting with advanced locoreGional diseases.
