Standardization of the extent of resection in nonradical neck dissections
- Conditions
- Head and neck cancer
- Registration Number
- JPRN-UMIN000003213
- Lead Sponsor
- The Japan Neck Dissection Study Group (JNDSG)
- Brief Summary
1. A total of 235 patients were enrolled between Feb. 18, 2004 and Nov. 22, 2006. 2. The follow-up of this study was completed on July 27, 2009. The percentage of patients with a follow-up less than 2 years was 2.3%. 3. Of the 79 questions of the observation form, difference among participating hospitals was confirmed in 13 details and strongly suspected in 7 details. 4. To standardize these 20 details, JNDSG established a manual, "Standard Surgical Maneuvers for Each Detail of Neck Dissection," based on the discussion about the optimal procedures concerning each detail. 5. As the study proceeded from the first to the second stage, the intensity of difference among the hospitals decreased in 11 details and increased in 6 details. Because there were more details showing decreased intensity, this study was concluded to have contributed to some extent to the standardization of nonradical neck dissections in Japan. 6. Although standardization of a surgical procedure in a multi-institutional setting is a very rare undertaking, this study achieved noteworthy success.
