Unlike traditional treatment, immunotherapies encourage the body's natural defences to target and destroy cancer cells, new research has revealed. But when the drugs work, responses can be long-lasting, and researchers are rushing to find ways to combine treatments to improve their effects and to determine which formulation is best for each patient.

In a second study, doctors found that giving Opdivo to advanced lung cancer patients before surgery helped shrink tumors and kill cancer cells.

The Phase 3 clinical trial followed more than 600 patients split into two groups: one that was given Keytruda with a standard chemotherapy treatment and a control group that only received the chemotherapy.

Pembrolizumab, sold under the brand name Keytruda, is an FDA-approved drug sold by a subsidiary of Merck & Company, Inc. that sponsored this study.

The series of studies was yesterday presented at the American Association of Cancer Research in Chicago.

"If you want to see long-term survival, youve got to give immunotherapy as soon as possible", Herbst said. "We have patients on these immunotherapies are alive more than eight years".

Two thirds were given a combination of both immunotherapy drugs and chemotherapy while the remaining patients were given chemotherapy and a placebo.

Notably, the incidence rate of lung cancer among non-smoking Chinese females is rising comparatively faster compared with those in western countries.

"What we look at in these trials is overall survival - how long patients live - and we look at a number called the median survival - how long 50% of patients live", said Gomez.

The immune therapy treatments worked for only about half of the patients in the study.

The estimated survival rate after 12 months for those that just received chemotherapy was 49.4 percent - in other words, just under half of those patients survived for a year.
