ABSTRACT
Background@#With the emergence of tyrosine kinase inhibitors and the incorporation of stringent measurable residual disease (MRD) monitoring, risk stratification for BCR-ABL1-positive acute lymphoblastic leukemia (ALL) patients has changed significantly. However, whether this monitoring can replace conventional risk factors in determining whether patients need allogeneic stem cell transplantation is still unclear. This study aimed to determine the impact of BCR-ABL1 monitoring on the outcome of patients with BCR-ABL1-positive ALL after allogeneic stem cell transplantation. @*Methods@#We retrospectively analyzed the survival outcome of patients with BCR-ABL1-positive ALL based on the quantification of BCR-ABL1 at 3 timepoints: the end of induction (timepoint 1), post-consolidation week 16 (timepoint 2), and the end of treatment for patients who were either transplant-eligible or non-transplant eligible (timepoint 3). @*Results@#From 2006 to 2018, a total of 96 patients newly diagnosed with BCR-ABL1-positive ALL were treated with chemotherapy and tyrosine kinase inhibitors. Thirty-eight (41.3%) patients achieved complete remission, and 33 patients underwent allogeneic stem cell transplantation. Our data showed that pre-transplant MRD monitoring by real-time quantitative polymerase chain reaction had the highest correlation with survival in patients with BCR-ABL1-positive ALL, especially for those who underwent allogeneic stem cell transplantation. @*Conclusion@#Patients without MRD pre-transplantation had superior survival compared with those who had MRD, and they had excellent long-term outcomes after allogeneic stem cell transplantation.

ABSTRACT
@#Osteoporosis is commonly underdiagnosed and undertreated. We performed a clinical audit to assess the risk factors and clinical care for osteoporosis among older persons who attended medical clinic during a 4-week period in August 2013. There was a total of 128 patients with a mean age of 73.1±5.8 years, and 20.3%. had a history of fall. Fracture Risk Assessment Tool (FRAX) scores assessment showed 14.2% and 68.8% had a 10-year risk of major osteoporotic and hip fractures respectively. Only 6.3% underwent Dual-energy X-ray absorptiometry (DXA) and 73.4% did not receive any preventive treatment for osteoporosis. Older persons attending medical clinic at high risk of osteoporosis fractures did not receive appropriate screening and treatment. There is a need to improve the suboptimal care for bone health among older persons.
