AbstractObjective To investigate the physics technique and quality assurance (QA) during radiotherapy in the institutions from the East Guangdong province, aiming to provide reference for the construction of radiotherapy discipline and rational allocation of resources in the primary hospitals from the eastern Guangdong province. Methods From March 15 to May 20, 2016, the general conditions, radiotherapy equipment, available technique and quality assurance (QA) in the medical institutions from eastern Guangdong were investigated and analyzed by online combined with on-spot surgery. Results There were 8 institutions which provided radiotherapy with 966 ward beds, a daily capacity of 632 patients and 222 radiotherapy practitioners. Radiotherapy equipment included 12 linear accelerators, 5 after-loading devices, 1γ-knife, 8 CT simulators and 9 radiotherapy planning systems. Five institutions performed IMRT/VMAT, IGRT and ART. Dose verification was performed before precision radiotherapy delivery in all institutions except for 1 center. QA procedures were missing for the linear accelerators, CT simulators and after-loading devices. Short-term advanced studies and hand-by-hand teaching were the main approaches for staff professional training. Conclusions The resource allocation for radiotherapy in the medical centers from the eastern Guangdong province is scarce. The technique and QC levels greatly differ among different institutions. Standard QA protocols are urgently to be established and implemented. Extensive attentions should be paid to the the professional training for technicians.
