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

Abstract: To determine outcome for equids with cutaneous neoplasms treated with cisplatin-containing biodegradable beads, alone or in conjunction with debulking. Methods: Retrospective case series. Methods: 56 horses, 1 zebra, 1 donkey, and 1 mule. Methods: Medical records were reviewed. Follow-up information was obtained through telephone conversations with owners and trainers of the animals. Results: 22 tumors were sarcoids, 6 were fibrosarcomas, 1 was a fibroma, 2 were peripheral nerve sheath tumors, 11 were squamous cell carcinomas, 14 were melanomas (13 gray horses and 1 bay horse), 1 was a lymphosarcoma, 1 was an adenocarcinoma, and 1 was a basal cell tumor. Forty-five (76%) animals underwent conventional or laser debulking of the tumor prior to bead implantation. Forty of 48 (83%) animals for which long-term follow-up information was available were relapse free 2 years after treatment. This included 20 of 22 animals with spindle cell tumors (including 11/13 horses with sarcoids), 6 of 10 animals with squamous cell carcinomas, 13 of 14 animals with melanomas, and 2 of 3 animals with other tumor types. Adverse effects were minimal. Conclusions: Results suggest that implantation of cisplatin-containing biodegradable beads, with or without tumor debulking, may be an effective treatment for equidae with various cutaneous neoplasms.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

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.
