Recent Advances in Reptile Oncology

Area of Science:

• Veterinary Medicine
• Reptile Oncology
• Comparative Pathology

Background:

• Reptile oncology literature has expanded significantly between 2016 and 2024.
• Tumors predominantly affect the integument and gastrointestinal tract across lizards, snakes, and chelonians.
• Diagnostic capabilities have notably advanced, enhancing lesion characterization.

Purpose of the Study:

• To review diagnostic investigations and treatments for reptile tumors.
• To analyze trends in reptile oncology over an eight-year period.
• To identify factors influencing successful treatment outcomes in reptiles.

Main Methods:

• Literature review of 74 reptile oncology cases (lizards, snakes, chelonians) from 2016-2024.
• Analysis of diagnostic modalities including radiography, ultrasonography, CT/MRI, endoscopy, and molecular techniques (IHC/PCR).
• Evaluation of treatment strategies encompassing surgical excision, chemotherapy, and radiotherapy.

Main Results:

• Integumentary and gastrointestinal tumors are the most common in all studied reptile species.
• Advanced imaging and molecular diagnostics are now frequently employed for precise lesion characterization.
• Surgical excision is the primary treatment, with adjuvant therapies used less frequently.
• Successful outcomes are linked to complete tumor excision and early patient presentation.
• Euthanasia decisions are influenced by treatment costs, tumor accessibility, and negative prognostic factors.

Conclusions:

• Modern diagnostic tools have improved the characterization of reptile tumors.
• Complete surgical excision and early diagnosis are critical for successful reptile cancer treatment.
• Treatment success in reptile oncology is multifactorial, involving diagnostic accuracy, surgical completeness, and patient factors.
