Application and Benefits of Web-Mediated Symptom Reporting for Patients Undergoing Immunotherapy: A Clinical Example

Two randomized studies of symptom monitoring during chemotherapy or during second line treatment and follow-up via web-based patient-reported outcomes (PROs) was previously demonstrated to lengthen survival. We are presenting here a patient with advanced and recurrent lung cancer who was followed for 4 years by PROs for relapse and adverse events detection. We report how the web-mediated follow-up helped to detect dangerous pulmonary embolism, relapse and pseudo-progression to immunotherapy by self-reported symptom tracking and specific algorithms triggering notifications to medical team, allowing early management of events. We particularly describe how a discordance between objective clinical improvement under immunotherapy assessed by the application allowed to detect pseudo-progression on imaging and allowed maintenance of the treatment during more than 1-year, although imaging report could have led to stop an effective therapy. The progression observed in the routine imaging was indeed in clear contradiction with improvements in patient's global status as assessed by the reduced PRO-score computed from patient self-reported symptoms. The ability of e-health tools based on symptoms reporting for tumor response assessment should be assessed in trials to help physician in decision of stopping or continuing therapy.
