45-Gy EQD2 elective nodal irradiation maintained 97% regional control in nasopharyngeal cancer
In 752 NPC patients, 45-Gy EQD2 elective nodal irradiation achieved 97.3% 5-year regional control with only 0.7% elective-volume failures.
In 752 NPC patients, 45-Gy EQD2 elective nodal irradiation achieved 97.3% 5-year regional control with only 0.7% elective-volume failures.
In 331 Danish NPC patients, five-year failure rates were similar by EBV status, while distant relapse was concentrated in locally advanced disease.
Among long-term NPC survivors treated with IMRT, radiation-related second malignancy incidence reached 6.66% at 15 years.
Adding advanced extranodal extension to N3 modestly improved prognostic discrimination and identified patients with substantially greater distant failure risk.
SPC-guided planning reduced larynx and parotid doses without compromising target coverage in a 200-patient retrospective nasopharyngeal carcinoma series.
Reducing the PTV–temporal lobe overlap dose to 66 Gy lowered five-year radiographic temporal lobe injury from 36.2% to 23.2%.
Adding parotid–target overlap shape features improved moderate-to-severe xerostomia prediction from AUC 0.66 to 0.78.
External validation achieved AUC 0.986, while modeled risk-adapted surveillance reduced visits by 90.0–98.5% and identified every observed failure.
Recurrent NPC with GTV LETd99 ≥39.4 keV/μm had 94.4% versus 65.3% two-year local control after carbon-ion reirradiation.
Five-year overall survival was 71%, with most distant failures occurring during the first three years after treatment.
Three-year PFS was 79.0% with induction TPF versus 74.5% with adjuvant PF, with substantially different toxicity profiles.
Updated level IVa delineation reduced predicted hypothyroidism from 43.9% to 34.9% without compromising target coverage.
Patient-specific stents improved tongue and parotid stability and were associated with substantially less hearing loss, dysphagia and dysgeusia.
TFDP2 activated PDK3, shifted nasopharyngeal carcinoma cells toward glycolysis, and reduced radiation response in cellular and xenograft models.
Response-guided target reduction has the strongest evidence, while proton therapy and immunotherapy-based de-escalation remain less established.
