The Anal Cancer On Line Workshop held by a great team of expert professors, with a long expertise on the topic, gave me the opportunity to expand my knowledge in contouring this rare disease. The clinical case, contoured by each participant gave me the chance to refresh the entire spectrum of staging of anal tumors, new developments in diagnosis and treatment and, of course, contouring. The faculty provided short hands-on lectures, which focused on guidelines and on questions/issues raised by the participants between sessions. All participants received an "on-line documentations" containing all lectures and key points articles. The On Line Workshop not only enriched my professional background but also served to extend these knowledge in the clinical practice. Furthermore, the "on line" modality allows to follow the course anywhere.
