A python named Jodie Foster has become the first snake to receive pioneering cancer treatment using electrochemotherapy, a breakthrough in veterinary medicine. The 15ft reticulated python, who lives at Chester Zoo, was diagnosed with a malignant tumour in her jaw that threatened her life. After surgery failed to fully remove the cancer, veterinarians turned to an innovative procedure typically used on humans, marking a historic moment for reptile care.
The Diagnosis and Initial Surgery
Jodie, a 50kg reticulated python, began showing signs of illness when she ate less and became inactive. Keepers noticed the change and brought her to the zoo's veterinary centre, where a fibrosarcoma—a malignant tumour—was discovered in her jaw. The tumour was surgically removed, but it returned and began invading her jawbone, making it difficult for her to eat.
With her condition worsening, the veterinary team faced a grim prognosis. Traditional surgery alone was not enough, and the risk of losing Jodie was high. This prompted them to explore alternative treatments, leading to the decision to adapt electrochemotherapy for a snake.
What Is Electrochemotherapy?
Electrochemotherapy is a cancer treatment that combines chemotherapy drugs with electrical pulses to increase the drug's absorption into tumour cells. It is commonly used in human medicine for skin and soft tissue cancers. The procedure involves administering a low-dose chemotherapy agent and then applying electric fields to the tumour site, which temporarily increases cell membrane permeability, allowing the drug to enter and destroy cancer cells more effectively.
For Jodie, the procedure was adapted to her unique anatomy. Because she was too large for a single operating table, two tables were pushed together to create a platform the size of a double bed. She was anaesthetised in her habitat and carefully transported to the veterinary centre, where the 90-minute procedure took place.
The Procedure and Recovery
Veterinary officer Ian Ashpole first removed the tumour and part of Jodie's diseased jawbone. Then, electrochemotherapy was applied to target any remaining cancer cells. The goal was to eliminate the cancer while preserving as much of her jaw function as possible, crucial for a snake that must unhinge its jaws to swallow prey.
Months after the procedure, Jodie is eating normally and has returned to her usual bright and feisty self. Zoo staff have observed her striking, gripping, and swallowing food without difficulty, indicating a successful outcome. This case demonstrates the potential of electrochemotherapy for treating cancer in reptiles and other exotic animals.
Comparison: Traditional Surgery vs. Electrochemotherapy
| Aspect | Traditional Surgery | Electrochemotherapy |
|---|---|---|
| Effectiveness | May leave residual cancer cells | Targets remaining cells with electrical pulses |
| Invasiveness | Requires extensive tissue removal | Minimally invasive after tumour removal |
| Recovery Time | Longer, risk of recurrence | Shorter, higher success rate |
| Use in Animals | Common but limited for complex cases | Rare, but now proven in snakes |
