Efficacy of the "Consilium" Smartphone App for Detecting Symptoms and Treatment Side Effects in Cancer Patients

The study investigates the influence of the use of a Smartphone App, on changes in general well-being and the occurrence of symptoms during a tumor therapy. With this documentation, medical professionals should be enabled to judge the influence of symptoms on quality of life during different time periods, between planed visits on site.

The study will examine the number, characteristics and intensity of electronically reported symptoms and therapy side effects depending on treatment and characteristics of patients with cancer of breast, colon, prostate, lung and hematological malignancies during a three-month period from the initiation of therapy. This period frequently represents the duration of a therapeutic regimen.

The level of agreement κ between the ECOG/CTCAE ratings by physicians at the time of the regular consultation, and the ratings derived from the daily PROs between consultations, will be analyzed in order to determine the reliability and utility of self-reported electronic symptom monitoring.

The purpose is to evaluate different qualities of symptoms self-reported electronically between consultations with respect to the course of treatment application, out-patient settings, gender and age. In particular, outpatients with frequent (weekly) consultations will be compared to patients with infrequent consultations (3-weekly or less frequent).

The study will also aim to identify the conditions and factors that might increase the likelihood of an unplanned consultation or emergency hospitalization.

In particular, the proposed study design and associated primary and secondary endpoints will enable us to test the following hypotheses:

1. In patient groups with infrequent outpatient visits (3-weekly or less) as is determined by the treatment schedule, the level of agreement κ between ePRO-derived ECOG/CTCAE ratings and physician-derived ECOG/CTCAE ratings (at time of consultation) is at least as high as in patient groups with weekly visits for symptoms having occurred within the week before the visit. However, κ is expected lower in the group with infrequent visits for symptoms having occurred more than 2 weeks prior to consultation, due to higher fidelity of ePRO-derived ratings for long-ago symptoms.
2. Regular visits of outpatients undergoing infusion therapy (as determined by the treatment schedule) do not significantly decrease the number of unplanned and emergency consultations necessary.
3. Young female and older male patient groups report significantly more severe and worsening symptoms and side effects.
