- Summary: The National Medical Products Administration (NMPA) published a recall event report on November 3, 2010, concerning Radiotherapy Planning Systems manufactured by Varian Medical Systems, Inc. The recall was managed in China by Varian Medical Device Trading (Beijing) Co., Ltd. The core issue identified was a software anomaly in the Eclipse radiotherapy planning system. Specifically, it was discovered that the field shape within the treatment chart could incorrectly change after converting from a 120-blade Multi-Leaf Collimator (MLC) to an 80-blade MLC. This malfunction had the potential to affect the accuracy of tumor radiotherapy plans. While the damage assessment indicated no actual harm, the potential for error necessitated a recall. The regulatory framework for this action falls under the NMPA's medical device recall protocols. The scope of affected products included 8 units of the Eclipse model, specifically identifying serial numbers such as H487682, H488405, and H488542 among others, applicable globally and sold within China. As a corrective action, Varian's China Customer Support Center issued an "Emergency Notice on On-site Safety Matters" to all relevant Chinese users. This notice served to alert users to the identified issue and provide necessary guidance. The implementation plan was reported as complete, with notices having been successfully sent to all affected users in China.
