Repurposed Medicines Spark Hope and Caution for Ugandan Cancer Patients

Uganda faces a growing challenge with over 37,000 new cancer diagnoses annually and a significant mortality rate, placing immense strain on its healthcare system. While cervical and prostate cancers are prominent, breast, Kaposi sarcoma, and oesophageal cancers also affect thousands.

Amidst this crisis, a scientific discussion is gaining traction concerning two established anti-parasitic drugs, ivermectin and mebendazole. Although not approved for cancer treatment, preliminary laboratory research suggests these inexpensive medications might possess anti-cancer properties.

Dr. Kathleen Ruddy, a cancer surgeon turned researcher, has highlighted decades of literature hinting at ivermectin’s potential beyond its antiparasitic use. This discussion is particularly relevant in Uganda, where cancer treatment is costly and access is often limited. The Uganda Cancer Institute, for instance, saw 8,372 new patients in the last financial year, with a notable percentage being children.

However, experts caution that early findings, primarily from lab and pre-clinical studies, do not equate to proven efficacy in humans. Studies have indicated ivermectin’s potential to disrupt cancer cell DNA repair and boost anti-tumour immune responses, while mebendazole has shown promise against various cancers in laboratory settings.

Despite this , researchers emphasize that laboratory results often fail to translate into successful human treatments. Regulatory bodies require robust clinical trial data before recommending any drug for widespread use. Dr. Ruddy herself clarifies that these drugs are not proven cures and should not replace conventional treatments.

The core question remains whether these medications can improve patient survival. While unanswered, the increased scientific focus on drug repurposing—exploring existing drugs for new uses—offers a potentially faster and more economical route to new therapies, given their known safety profiles.

For Uganda, the pursuit of affordable and effective cancer treatments is a critical public health necessity. Health officials urge patients to continue with evidence-based care while research progresses. The ongoing scientific investigation into drugs like ivermectin and mebendazole represents a vital development for thousands of Ugandan families grappling with cancer.
