Summary
This study found that 5-fluorouracil, a cancer treatment, significantly increased lung tumors in male and female mice. It also caused lymphoreticular system tumors in females, indicating carcinogenicity.
Area of Science:
- Oncology
- Toxicology
- Carcinogenesis research
Background:
- 5-Fluorouracil (5-FU) is a widely used chemotherapeutic agent for gastrointestinal neoplasms.
- Assessing the long-term carcinogenic potential of 5-FU is crucial for patient safety.
Purpose of the Study:
- To evaluate the carcinogenicity of 5-fluorouracil in a preclinical mouse model.
- To determine the specific tumor types and sexes affected by 5-FU treatment.
Main Methods:
- BALB/c mice (both sexes) received intraperitoneal injections of 5-fluorouracil at 30 mg/kg weekly for 50 weeks.
- Tumor incidence was statistically analyzed to determine significance.
Main Results:
- A significant increase in lung tumors was observed in both male (p < 0.05) and female (p < 0.01) mice.
- Female mice exhibited a significant increase in lymphoreticular system tumors (p < 0.001).
Conclusions:
- 5-Fluorouracil demonstrates carcinogenic activity in BALB/c mice.
- The findings highlight potential risks associated with 5-FU exposure, necessitating further investigation.
