On-and-off Approach To Prostate Cancer Treatment May Compromise Survival

Survival among the two groups showed a 10 percent relative increase in the risk of death with intermittent therapy, with average survival of 5.8 years for the continuous group and 5.1 years for the intermittent group from the time of randomization.

Further, the researchers looked at quality of life between the two groups of patients. Initially the intermittent therapy group showed significant improvement in impotence and emotional function in the first three months and had improved trends in other aspects of quality of life compared to the continuous group. But these differences leveled off over time. 

"The improvements in some aspects of quality of life that were observed early were not sustained after a few months as patients had to resume therapy," says Hussain professor of internal medicine and urology at the U-M Medical School.

"If a patient is coming in with newly metastatic prostate cancer, hormone treatment continuously is the standard. If they wish to do intermittent treatment, they should be counseled that based on this data, their outcome might be compromised," she adds.

Follow-up studies are investigating a new generation of anti-hormone treatments combined with current therapies in the hopes of increasing the treatment's effectiveness. For information about currently available clinical trials at U-M, call the Cancer AnswerLine at 800-865-1125.
