Brief summary

AdOTAC is a pilot study, open, prospective, single-center, one-arm. The 200 patients will be included. Patient is included at Day 0. The included patient will have the opportunity to complete the self-questionnaires either at the ICL on Day 0, or at home up to 10 days after the date of inclusion in the study. Blood samples are collected the day of enrolment (Day 0) in order to measure the following biological markers: ferritin, serum iron, TSAT, albumin, and haemoglobin, except if performed as part of routine care in the previous 6 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Assess medication adherence to oral treatments in patients with advanced breast or prostate cancer.one dayMedication adherence to oral anticancer treatments will be assessed using a score based on the GIRERD adherence assessment (targeting oral anticancer treatments). The score is a scale ranging from 0 to 6 (good compliance = 6; poor compliance = 4 to 5; non-adherence ≤ 3).

Secondary

MeasureTime frameDescription
Identify if the performance status by the ECOG-PS score is associated with reduced adherence to oral anticancer treatmentsone dayThe performance status by the ECOG-PS score (0 to 4).
Identify if comorbitities is associated with reduced adherence to oral anticancer treatmentsone dayComorbidities using the Charlson score (0 to 37).
Identify if polypharmacy by the use of five or more medications apart from the current oral anti-cancer medications is associated with reduced adherence to oral anticancer treatmentsone dayPolypharmacy by the use of five or more medications apart from the current oral anti-cancer medications (0 to \>5).
Identify if treatment regimen by a level of complexity is associated with reduced adherence to oral anticancer treatmentsone dayThe treatment regimen by a level of complexity (4 levels) given by an oncologist.
Identify if biological markers are associated with reduced adherence to oral anticancer treatmentsone dayBiological markers (ferritin, TSAT, serum iron, haemoglobin, albumin) by a blood test.
Identify if sarcopenia is associated with reduced adherence to oral anticancer treatmentsone daySarcopenia by the body mass/fat mass ratio using imaging (SMI: skeletal muscle mass index).
Identify if quality of life using the EORTC-QLQ-C30 questionnaire score is associated with reduced adherence to oral anticancer treatmentsone dayQuality of life using the EORTC-QLQ-C30 questionnaire score.
Identify if Social and emotional support by the MSPSS questionnaire is associated with reduced adherence to oral anticancer treatmentsone daySocial and emotional support by the MSPSS questionnaire (Multidimensional Scale of Perceived Social Support) (12-35: low perceived support; 36-60: medium perceived support; 61-84: hugh perceived support)
Identify if HADS scale is associated with reduced adherence to oral anticancer treatmentsone dayAnxiety and/or depression using the Hospital Anxiety and Depression Scale (HADS). (If the score in a column is greater than or equal to 11, it means person suffer from anxiety or depression)
Identify if MNA is associated with reduced adherence to oral anticancer treatmentsone dayMalnutrition using the MNA (Mini-Nutritional Assessment) questionnaire (24-30 points: normal nutritional status; 17-23.5 points: at risk of malnutrition; less than 17 points: malnourished)
Identify if Use of social networks and alternatives and complementary medicines using patient questionnaire is associated with reduced adherence to oral anticancer treatmentsone dayUse of social networks and alternatives and complementary medicines using patient questionnaire developed specifically for the study population.
Assess medication adherence to oral treatments in patients with advanced breast or prostate cancer.one dayMedication adherence to oral anticancer treatments will also be assessed using the score from the new AdOT questionnaire. The score is a scale ranging from 0 (no adherence) to 100 (perfect adherence).
Study the relationship between the two adherence questionnaires.one daySubgroup analysis by cancer type (breast; prostate), use of alternatives and complementary medicines (yes; no) and use of social media and networks (yes; no).
Describe and compare medication adherence to oral treatmentsone dayThe correlation between the scores on the GIRERD and AdOT will be analysed.
Describe and compare patient characteristics (socio-demographic, clinical and contextual), medication adherence to oral anticancer treatments according to cancer type, use of alternative and complementary medicines and use of social media and networks.one daySubgroup analysis by cancer type (breast; prostate), use of alternative and complementary medicines (yes; no) and use of social media and networks (yes; no).
