Use of cisplatin-containing biodegradable beads for treatment of cutaneous neoplasia in equidae: 59 cases (2000-2004).

The research article studies the efficacy of using cisplatin-containing biodegradable beads for treating skin tumors in horses and other similar animals. The study found that most of the animals treated with this method were tumor-free two years post-treatment, suggesting this may be an effective treatment approach.

Study Objective and Methods

• The main objective of the study was to determine the treatment outcomes for horses (equids) with skin tumors (cutaneous neoplasms) using cisplatin-containing biodegradable beads. The beads were used either alone or in combination with debulking, a surgical procedure to remove some or all of a tumor.
• This retrospective case series involved 59 animals, including 56 horses, a zebra, a donkey, and a mule.
• Treatment and outcomes were gathered by reviewing the animals’ medical records and through telephone follow-ups with the animals’ owners and trainers.

Tumor Types and Treatment Approaches

• The animals in the study had various types of tumors, including sarcoids, fibrosarcomas, fibromas, peripheral nerve sheath tumors, squamous cell carcinomas, melanomas, lymphosarcomas, adenocarcinomas, and basal cell tumors.
• Approximately 76% of the animals underwent conventional or laser debulking of the tumor prior to the bead implantation.

Results of the Study

• Of the 48 animals for which long-term follow-up was available, 83% were free from cancer (relapse-free) 2 years after treatment. This result included data from various types of tumors.
• Adverse effects from the treatment were minimal, suggesting the treatment was not only effective but also safe.

Conclusion of the Research

• The results of the study support the use of cisplatin-containing biodegradable beads, with or without tumor debulking, as a potentially effective treatment for horses and other similar animals suffering from various types of skin tumors.
