Improving the consistency in cervical esophageal target volume definition by special training.

PURPOSE: Three-dimensional conformal radiation therapy requires the precise definition of the target volume. Its potential benefits could be offset by the inconsistency in target definition by radiation oncologists. In a previous survey of radiation oncologists, a large degree of variation in target volume definition of cervical esophageal cancer was noted for the boost phase of radiotherapy. The present study evaluated whether special training could improve the consistency in target volume definitions. METHODS AND MATERIALS: A pre-training survey was performed to establish baseline values. This was followed by a special one-on-one training session on treatment planning based on the RTOG 94-05 protocol to 12 radiation oncologists. Target volumes were redrawn immediately and at 1-2 months later. Post-training vs. pre-training target volumes were compared. RESULTS: There was less variability in the longitudinal positions of the target volumes post-training compared to pre-training (p < 0.05 in 5 of 6 comparisons). One case had more variability due to the lack of a visible gross tumor on CT scans. Transverse contours of target volumes did not show any significant difference pre- or post-training. CONCLUSION: For cervical esophageal cancer, this study suggests that special training on protocol guidelines may improve consistency in target volume definition. Explicit protocol directions are required for situations where the gross tumor is not easily visible on CT scans. This may be particularly important for multicenter clinical trials, to reduce the occurrences of protocol violations.

Continuing medical education in Turkey: recent developments.

BACKGROUND: The Turkish Association of Medicine founded a Continuing Medical Education Accreditation Committee in 1993 to evaluate and accredit scientific meetings and publications. The aims of this project were to raise the standards of meetings and to introduce compulsory revalidation and re-certification for physicians in Turkey. DISCUSSION: Since the year 1994, 2348 applications to the Continuing Medical Education board have been made (mostly for scientific meetings), and 95% of these applications have been accepted. Physicians received 139.014 credits during this time. This number is increasing every year. Meeting organisers' demand for such a kind of evaluation is increasing, because participants increasingly request it. SUMMARY: Efforts for revalidation and re-certification of physicians have not been completely successful yet. In the near future the Co-ordination Council of Medical Speciality Societies is going to oblige member associations to establish speciality boards. This will be the first step to the conventional use of Continuing Medical Education credits in occupational evaluation. Time-limited re-certification of physicians is the principal goal of Turkish Medical Association. Efforts to implement this change in legislation are being made.
