A new treatment for liver cancer has been found to be effective in almost 90 percent of patients.

The study, pioneered at University Hospital Southampton, isolated the liver before “bathing” it in chemotherapy.


The procedure, known as chemosaturation therapy or percutaneous hepatic perfusion, allows doctors to administer much larger doses of drugs than standard chemotherapy because it does not enter the bloodstream and cause unnecessary potential damage to healthy parts of the body.

Once the drug is administered, blood from the liver is drained from the patient and processed through a filtration machine to reduce toxicity, before being returned to the patient via the jugular vein.

The team, led by University Hospital Southampton's consultant interventional radiologist Dr Brian Stedman, said it performed 300 procedures in 100 patients whose form of eye cancer known as ocular melanoma had spread to the liver.

The study was published in the Melanoma Research journal and found liver cancers were controlled in 88.9% of patients who had received chemosaturation therapy, with 62% of them surviving for a year and 30% after two years.

Dr Stedman, who is also co-founder of PLANETS cancer charity which helped fund the research, said: “When we first trialled this treatment on two patients in 2012 I said that the development would be a landmark moment in cancer care and it really has proved to be, given these results.

The procedure, known as chemosaturation therapy or percutaneous hepatic perfusion (PHP), has been pioneered in the UK by Dr Brian Stedman, a consultant interventional radiologist at University Hospital Southampton, and involves using two small balloons to divert blood past the liver for an hour while delivering drugs directly in to the organ.

“This treatment allows us to cut off an organ from the body for 60 minutes, soak it in a high dose of drug and then filter the blood almost completely clean before returning it, and its arrival was much-needed.

“The outlook for patients specifically suffering from cancer which has spread to the liver has been notoriously poor because the effect of standard chemotherapy is limited by the unwanted damage the drug causes to the rest of the body.

“Chemosaturation therapy offers the possibility of repeat intervention and these results demonstrate it offers excellent short and medium-term disease control with improved survival.

“With such a large series of results, it also proves the safety of the system, with patients feeling back to normal within days and maintaining an excellent quality of life during treatment by avoiding many of the unwanted side-effects of standard chemotherapy.

“This novel approach demonstrates the ability of science and technology to harness the power of imaging and target cancer treatment to the areas in which treatment is needed but avoid the unwanted damage caused by conventional chemotherapy or surgery on normal tissue.”

A spokesman for PLANETS said the average survival length of those studied was 15 month, but in some cases, ongoing cycles of chemosaturation therapy have almost removed patients’ cancers completely.

He added: “However, despite being incorporated into the available treatment options by the National Institute for Health and Care Excellence (Nice) last year, there is not currently an NHS-commissioned service.”

Study co-author Neil Pearce said: “While we currently only have evidence for this treatment in liver cancer which has spread from the eye, these results may now open the door for future studies with other difficult-to-treat cancers affecting the liver and we are exploring the potential new research trials.

“There has also been some limited research and case reports in other cancers – including bowel, breast, pancreatic and neuroendocrine – from international centres which suggest potential benefit but would need to be more formally assessed in large clinical trials.

“But these findings show there is real potential for this treatment to extend to more common cancers, which is very exciting.”
