It is possible to achieve the same benefits in online models than in face to face programs in breastcancer patients. Introduction: eHealth programs is an emerging area because of the restricted measures for controllingCOVID19 pandemic, to maintain high quality patients’ care. In this sense, Spanish Cancer Associationof Madrid (AECCmad) had an effective exercise oncology face-to-face program that had to be adaptedinto the online model. The purpose of this study is comparing the results from the face-to-face (F-F)initial program with the new one, to evaluate the efficacy of the online model in breast cancer patients(BCP). Methodology: Since 1st of September of 2018 until 31 of March of 2021, a total of 267 BCP in differentstages were assisted in the exercise-oncology unit of the AECCmad: from 2018 to December 2019, 180BCP participated in F-F programs and from September 2020 to March 2021, 87 BCP participated inonline interventions. In both cases, BCP were initially evaluated to checked fulfilled the inclusioncriteria by a nurse. After that, BCP had a one-to-one interview with the exercise-oncologyprofessionals where anthropometrics, cardiorespiratory fitness (CRF), strength, and functionalcapacity was assessed. Then, BCP were included in a supervised exercise program (F-F or online) witha duration of 12 or 8 weeks, respectively, 2 days per week, performing combined exercise andadapting the intensity to each patient. At the end, the same variables were assessed with a twofoldpurpose: to inform patients of the achieved changes and to give them a personalized final report thatwould help women to continue doing exercise. Data were analyzed using SPSS 20, comparingdifferences between interventions with ANCOVA test for quantitative variables or Chi2 test forqualitative variables. Results: 267 BCP completed the exercise-oncology program of AECCmad. 180 participated in the F-Fprogram with a mean age of 52.3(9.0) (50% survivor, 32% undertreatment and 16% with metastaticdisease) and 87 participated in the online version with a mean age of 45.7(10.1) (30% survivor, 51%undertreatment and 20% with metastatic disease). Participants in online groups were significantlyyounger than in F-F groups (MeanDif (ΔM)= 6.6, CI95%= 9.2 - 3.9, p&lt;0.001).Related to programadherence, F-F program had a significant higher adherence than the online model (ΔM=10.2, CI95%=15.9 - 4.4, p=0.001). Related to physical results, CRF and leg strength were significantly higher in F-Fgroups compared with the online model (ΔM= 3.4; CI95%= 0.04-6.7; p= 0.047; and ΔM= 11.6; CI95%=3.6 -19.4; p= 0.005, respectively). By contrast, no differences in strength of upper limbs (ΔM= 0.39; p=0.79) between groups were observed although F-F intervention achieved higher final values than theonline ones. Regarding to body composition, no significant difference in muscle mass (ΔM= 0.1; p=0.66), fat mass (ΔM= -0.9; p= 0.12), and visceral fat mass (ΔM= -5.8; p= 0.08), were observed betweengroups, although better results were observed in F-F interventions. Conclusions: Although F-F and online exercise-oncology programs both improved physical status,these comparisons showed that programs F-F are more effective improving CRF and legs strength thanonline ones, probably due to F-F programs were longer and used specific material. In addition,adherence to F-F programs was significantly higher than the online version, maybe for the reductionof the social aspect in the last one. However, online intervention had similar impact in bodycomposition than F-F ones and allows for greater access to patients in general, but specially those withlow accessibility, living in longer distance, or having difficulties in moving, among others. In this sense,these comparisons suggest online programs should be an effective alternative to improve physicalaspect in BCP.
