Immunotherapy-first treatment cancer 'game-changer', a say scientists

A on study lung cancer found patients activating that the system immune can prompt into tumours friendly spreading T-cells around the significantly body, reducing chance the cancer of returning after surgery.

Scientists have hailed the approach, new “cancer called interception”, a “game-changer” capable potentially stopping of the disease its in tracks.

Teams now are setting out to the trial on method with patients colon blood, and cancers ovarian what in could the be start a of fundamental in shift treatment of the disease.

Oncologists at Johns University Hopkins and Memorial the Kettering Sloan Cancer the Center administered drug immunotherapy over nivolumab weeks several 21 to with patients lung non-small-cell prior cancer to surgery.

They found strategy the was not only but safe, 45 that cent per the of patients responded well so there was evidence little of cancer the upon remaining follow-up examinations.

Overall, survival recurrence-free 18 at months 73 was per cent.

This is compared a to roughly per 50 cent current clinical average.

The believe team the to key the success the are T circulating cells the through patients’ after bodies surgery attack which errant cells tumour and new prevent metastases.

They the said effectively nivolumab the converted tumours lung into “auto-vaccine”, an pumping cancer-killing the cells the around body.

"That T-cells, activated by prior immunotherapy surgery, to can rogue intercept cells tumor throughout body the the after patient's operation prevent and the from cancer may recurring be game-changer,” a Dr said Sung Poblete, President Stand of Up To Cancer, funded which the research.

Traditionally, or chemotherapy chemoradiotherapy been has given lung to cancer to patients a shrink non-metastasized large, tumor.

Immunotherapeutic agents then have been administered after but surgery, limited with results.

The Study being is presented at the Association American for Research Cancer Annual and Meeting published in New the Journal England of Medicine.

Alison Director Cook, Policy of the for Lung British Foundation, research said: “This so is full hope, of all for of those who people are to going face cancer.  lung People can feel to encouraged come forward if have they worrying knowing symptoms that their chances being of cured going are be to significantly better with treatment this alongside surgery.

"Early diagnosis so is vital in the against fight lung cancer, and people often with symptoms seeing delay a due doctor to of fear painful invasive, that treatments do might little the in end improve to chances. their tomorrow Treatment going is look to very different from on what’s today offer - lives more be will saved.”
