A large python diagnosed with cancer was treated with electrochemotherapy and survived, in what is reported as the first such case in a reptile.

What electrochemotherapy is

The technique administers a chemotherapy agent and then applies brief, intense electrical pulses to the tumour site. The electrical stimulation temporarily raises cell membrane permeability so the drug enters tumour cells more readily.

The advantage is reducing the amount of drug circulating systemically. Achieving the same effect with a lower dose lowers the side-effect burden. The method is already in use in human oncology and in companion animal medicine.

Why a reptile is difficult

Reptiles differ from mammals in metabolic rate and thermoregulation, which complicates drug metabolism and anaesthesia management. No standard protocol for cancer treatment effectively existed. This case shows that a localised technique can be applied under those conditions.

Generalising from a single successful case would be premature. Differences between species, responses by tumour type and long-term prognosis all require further cases before conclusions can be drawn.

Techniques accumulated in veterinary medicine sometimes return to human treatment. The more extreme the subject's physiology, the more clearly a method's limits and safety margins show themselves.
