PURPOSE: To assess the overall treatment time of radiotherapy delivered with curative intent in a cohort of 185 consecutive patients and the causes of this possible delay. If delay, to propose corrective actions.
MATERIALS AND METHODS: We report a single-center prospective study including all consecutive patients receiving a radiation therapy with curative intent, from 1st December 2013 to 28th February 2014, on the three linear accelerators of the radiotherapy department. For each fraction missed, the causes of non-completion were prospectively collected. This analysis took into account the following parameters: age, sex, occupation, transport type and duration, tumour localization, radiation dose, concomitant chemotherapy, hospitalization, type of linear accelerator.
RESULTS: One hundred and fifty-five patients were included in the study (183 evaluable, two did not complete treatment). The overall treatment time was respected for 31 patients (17%). It was lengthened on 4.6 days (d) (0-29 d; median: 3d). The mean number of delayed fractions was 3.4 (0-17; median: 2). The reasons of delay were: breakdown 32.2%; maintenance 29.3%; holiday 11%; treatment toxicity 9.4%; inadequate planning 8.6%; other disease 3.9%; treatment refusal 2.1%; unspecified personal reasons 1.5%; refusal to wait 0.8%; transportation 0.3%; error of communication 0.3%; other 0.6%. Two parameters had a significant impact on the overall treatment time: the type of linear accelerator in relation to breakdown occurrence (P<0.001) and transportation duration (more or less than 40 min, P=0.022). One hundred and thirty-eight patients (75%) and 79 patients (43%) were treated on one or more than two Saturdays. Treatment on Saturday significantly reduced the overall treatment time (median, 1.9 d; P<0.001).
CONCLUSION: The overall treatment time was globally respected excluding break down and maintenance. Their impact on the overall treatment time is minimized by the systematic opening of the department on Saturdays.
