RESUMO

PURPOSE: The objectives of the present study was to evaluate the implementation of the program in real life and the evolution of the quality of life (QoL) in breast cancer patients after 3 months of supervised PA in real life and to determine the factors associated with changes in various QoL dimensions. METHODS: This prospective cohort study was carried out in female patients with breast cancer diagnosed within a maximum of 3 yr. QoL and physical exertion intensity during the supervised physical activity (PA) sessions were assessed by the Quality of Life Questionnaire for Cancer and Borg scale, respectively. Statistical analyses comparing QoL scores between the start and the end of supervised PA program were assessed using paired Student's t -tests. Multivariate analysis was performed by linear regression with only variables with a P value <0.15 in univariate model. RESULTS: A total of 93 patients were included in the analyses. There was a significant improvement of social functioning at T3 (∆ = 11.5; P < 0.001). The improvement of social functioning was significantly and independently associated with the Borg improvement ( ß = 2.66 ± 1.31, P = 0.046), chemotherapy ( ß = 11.03 ± 5.45, P = 0.046), hormone therapy ( ß = -13.91 ± 5.51, P = 0.013), social isolation ( ß = -14.81 ± 6.55, P = 0.026), and comorbidities ( ß = -15.32 ± 5.59, P = 0.007). CONCLUSIONS: We observed a real enthusiasm and need among patients for practicing PA supervised by a sport trainer near their home. The increase in the intensity of exercise over time contributes to the improvement of the QoL, especially on the social functioning. These results, consistent with previous literature, reinforce the importance of exercise intensity on many dimensions of QoL. In addition, patients expressed great satisfaction with the supervised program, resulting in a strong desire to maintain long-term PA.

RESUMO

The benefits of regular physical activity (PA) are essential and recognized, including for cancer patients, during and after treatment. The OncoNormandie regional cancer network therefore offers an adapted physical activity support system that facilitates access for cancer patients.

RESUMO

Besides the detection of somatic receptor tyrosine kinases (RTK) mutations in tumor samples, the current challenge is to interpret their biological relevance to give patients effective targeted treatment. By high-throughput sequencing of the 58 RTK exons of healthy tissues, colorectal tumors, and hepatic metastases from 30 patients, 38 different somatic mutations in RTKs were identified. The mutations in the kinase domains and present in both tumors and metastases were reconstituted to perform an unbiased functional study. Among eight variants found in seven RTKs (EPHA4-Met726Ile, EPHB2-Val621Ile, ERBB4-Thr731Met, FGFR4-Ala585Thr, VEGFR3-Leu1014Phe, KIT-Pro875Leu, TRKB-Leu584Val, and NTRK2-Lys618Thr), none displayed significantly increased tyrosine kinase activity. Consistently, none of them induced transformation of NIH3T3 fibroblasts. On the contrary, two RTK variants (FGFR4-Ala585Thr and FLT4-Leu1014Phe) caused drastic inhibition of their kinase activity. These findings indicate that these RTK variants are not suitable targets and highlight the importance of functional studies to validate RTK mutations as potential therapeutic targets.
