Centre Saint-Jean

Centre Saint-Jean, operating as Centre d'oncologie et de radiothérapie Saint-Jean, is a French healthcare facility dedicated to oncology and radiotherapy. The center delivers cancer treatments, including chemotherapy and radiotherapy, alongside medical consultations for patients. Its services are focused on providing specialized cancer care within a clinical setting. As an oncology-specific institution, it addresses the therapeutic needs of individuals requiring radiation-based and chemical treatments for cancer. The facility operates in France, serving a local patient population with these specialized medical services.

In November 2022, the center suffered a ransomware attack that severely disrupted its information systems and compromised various data sets, including patient medical records. The attack forced the temporary suspension of chemotherapy and radiotherapy treatments, although medical consultations continued without interruption. In response, the center activated its crisis protocols and worked with regional health authorities to redirect patients needing urgent care to nearby facilities. Compromised servers were isolated, and a new secure infrastructure was deployed to restore operations. The incident was reported to the national data protection authority, and patients were directly informed about adjustments to their care. Despite the disruption, chemotherapy treatments later resumed while radiotherapy remained halted temporarily during the recovery period. The center's handling of the incident demonstrated its established emergency response procedures and integration within the regional healthcare network.
