At some point in cancer patient’s disease experience, chemotherapy is used, and the patient is expected to adhere to treatment to improve survival and quality of life. Methods: This multisite Cluster Randomized Trial (CRT) evaluated the effectiveness of mobile phone Short Message Service (SMS) support on the adherence to treatment schedules among adult cancer patients in Kenya. Data was collected using questionnaires. Ethical approvals were obtained from relevant Ethical Review Boards (ERBs). Results: The mean adherence was 83%. There was a significant difference between treatment arms in relation to the adherence. The intervention arm had a higher mean adherence difference, M = 3.913, 95% CI 2.632-5.193, t (402) = 6.006, p ≤ 0.001), with Cohen’s d = 0.60. Although not significant, (χ<sup>2</sup>dd = 0.151, df = 1, p = 2.064), more women were perfect adheres than males. Perfect adherers were satisfied with SMS support (χ<sup>2</sup>dd = 7.620, df = 1, p = 0.06), were in the intervention arm (χ<sup>2</sup>dd = 22.942, df = 1, p ≤ 0.001), and had trust in the care provider (χ<sup>2</sup>dd = 10.591 p ≤ 0.001). SMS support was not significant in the multivariate analysis but had an estimated effect size of 0.958 (z = 1.424, p = 0.154, CI = 0.242-3.781), indicating that mean adherence was slightly better in the presence of the intervention. Conclusions: SMS-support intervention has demonstrated superiority in influencing adherence. Further, health system-related factors have a significant influence on the adherence to chemotherapy treatment. Interventions to re-design health systems that are responsive to unmet care needs of cancer patients must be explored. .展开更多

When suspicious FDG accumulation was found in ALN, the presence of metastasiswas reevaluated by second US. We examined predictors of upstaging from N0 to pN2a/pN3a.RESULTSAmong 135 patients, we identified 1-3 ALNs (pN1) in 113 patients and ³4 ALNs (pN2a/pN3a) in22 patients. Multivariate analysis identified the total number of SLN metastasis, the maximaldiameter of metastasis in the SLN (SLNDmax), and FDG accumulation of ALN as predictors ofupstaging to pN2a/pN3a.CONCLUSIONWe identified factors involved in upstaging from N0 to pN2a/pN3a. The SLNDmax and numberof SLN metastasis are predictors of ≥ 4 ALNs (pN2a/pN3a) and predictors of metastasis to nonsentinelnodes, which have been reported in the past. Attention should be given to axillaryaccumulations of FDG, even when faint.展开更多
