Supportive care has become a new pilar of modern oncology, and a great deal of research is being conducted in that area, especially on immune checkpoint inhibitors (ICIs), to help fine-tune immunotherapy. Four major areas of supportive care can enhance responsiveness to cancer immunotherapy whilst minimizing adverse effects: diet (indirectly, by modulating the microbiota or directly, by modulating the immune system), physical activity (by modulating the immune system), electronic patient-reported outcomes (ePRO) (by detecting and treating immune-related adverse events early on), and co-medication management (to possibly suppress those drugs that negatively affect the efficacy of ICIs). Therefore, patients treated with ICIs could receive a systematic multimodal supportive care program encompassing regular nutritional counseling, regular physical activity under the supervision of a physical activity professional, ePRO follow-up, and regular pharmaceutical counseling. This type of approach needs to be evaluated in well-conducted randomized clinical trials., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Introduction: Oral targeted therapies (OTTs) are widely used for cancer management. However, there is no consensus on OTT dose adaptation in older patients with cancer., Methods: This noninterventional, retrospective study was a real-life assessment of dose adaptation for six OTTs (afatinib, everolimus, palbociclib, pazopanib, sorafenib and sunitinib), at baseline and during treatment, and the reasons for the changes, in ≥70-year-old patients treated between February 2016 and August 2019. Data were compared with univariate models fitted with all variables., Results: Among the 986 patients treated with OTT, the group of ≥70-year-old patients (n = 122) received afatinib (15.6%), everolimus (14.8%), palbociclib (50.8%), pazopanib (9.8%), sorafenib (5.8%) or sunitinib (3.2%). At baseline, the prescribed OTT dose was adapted (reduction) in 29% of ≥70-year-old patients (35/122). These 35 patients were significantly older (mean age 80 vs 74 years, P < .001), and more frequently had a performance status score ≥2 (P < .01) than the other patients (n = 87). In the standard dose group, higher toxicity grades (P = .18) and subsequent dose reduction (41% of patients, 36/87) tended to be more frequent compared with the baseline adapted dose group (26%, 9/35, P = .1). At the study end, 53% of patients in the whole cohort (65/122) were taking a lower dose than the recommended one., Conclusion: At OTT initiation, dose was adapted in 29% of older adults with cancer, rarely after a formal oncogeriatric evaluation (6.5% of all patients). In the absence of recommendations, clinical studies are needed to evaluate the efficacy and safety of baseline OTT dose reduction in older adults with cancer., (© 2022 British Pharmacological Society.)
