Acute myeloid leukemia (AML) can be a challenging condition to manage, especially during intensive chemotherapy. However, recent research published in Blood Advances by Mouchel et al. suggests that vitamin C and D supplements may offer a ray of hope. The study revealed some interesting findings regarding complications and certain patient subgroups.
The Role of Vitamin C and D in AML
AML is a complex disease, and researchers have been exploring various ways to improve treatment outcomes. Previous studies hinted at the potential benefits of vitamin D in reducing the risk of posttransplant relapse, while vitamin C was investigated for its role in suppressing the development of leukemic cells.
Lead study author Christian Récher, MD, from the University Cancer Institute of Toulouse, France, noted, “To the best of our knowledge, this is one of the first studies to examine the potential effects of vitamin C and D supplementation during intensive chemotherapy for AML.” The goal was to determine whether supplementation could reduce adverse events associated with the demanding treatment regimen.
The study analyzed data from 431 AML patients treated with intensive chemotherapy over five years, with 169 patients receiving vitamin C and D supplements and 262 serving as controls. The supplementation group saw an increase in vitamin D levels from 18 ng/mL at diagnosis to 39 ng/mL post-chemotherapy, approaching the normal range of 20 ng/mL to 50 ng/mL. Vitamin C levels remained relatively stable, possibly due to a conservative dosage of 6 g per week.
The results were particularly interesting in terms of complications. Patients receiving supplements experienced lower rates of moderate-to-severe bacterial infections (27.2% vs. 35.1%), bleeding (1.8% vs. 5.7%), and potentially life-threatening immune system inflammation (1.8% vs. 8.8%) during intensive chemotherapy compared to the control group. Overall survival rates did not significantly differ between the two groups, but a subgroup analysis revealed a 48% reduction in the risk of mortality among patients with NPM1 mutations who received supplements.
While these findings are promising, the researchers stressed the need for further investigation in larger, randomized studies to confirm the association and understand the underlying mechanisms behind improved survival in patients with NPM1 mutations.
Despite limitations, the results offer encouragement and support the potential for clinical trials involving vitamin C and D administration in AML patients. This study brings us closer to understanding how these vitamins may play a role in enhancing the treatment journey for individuals battling AML.
