This study was designed to evaluate the prognostic value of plasma pretreatment EBV DNA in children and adolescent NPC patients receiving intensity-modulated radiotherapy (IMRT).Methods: Pretreatment EBV DNA was retrospectively assessed in 147 children with newly diagnosed, non-metastatic NPC. All patients were treated using IMRT. Receiver operating characteristic (ROC) curve was used to identify the optimal EBV DNA cutoff point. Prognostic value was examined using a multivariate Cox proportional hazards model.Results: The median follow-up for the entire cohort was 58 months (range, 10–119 months), and the 5-year sur...

Objective: To study the dosimetric effect on special reconstruction images obtained from an electrocardiograph-gated four-dimensional computed tomography (ECG 4D-CT) series and compare it with the accumulation dose assessment of ECG 4D-CT.Methods: Fifteen patients underwent ECG 4D-CT scans to obtain a 4D-CT series. The 20 phase images of 0–95% were reconstructed at intervals of 5% of the cardiac cycle by the 4D-CT series. The 4D-CT series was specially reconstructed, and the maximum intensity projection (MIP), minimum intensity projection (MinIP), average intensity projection (AIP), and sum intensity projection (SIP)...

In terms of Pro fees only, how many IMRT fractions provides more billing than an SBRT course? Ie. At what point does IMRT pass SBRT? I’m sure someone has done the math before. My Guess is somewhere around 15 frac?

CONCLUSION: Once weekly low dose cisplatin treatment showed lower acute toxicity and a better compliance compared to once every 3 weeks high dose cisplatin treatment at the expense of a lower loco-regional control. PMID: 32212810 [PubMed - in process]

CONCLUSION: The IMRT planning strategy employed in the ACCEL trial demonstrated consistent and superior dosimetry by comparison to conventionally used 3D CRT techniques. Future APBI trials should update dosimetric constraints. PMID: 32224317 [PubMed - as supplied by publisher]
