Patients with cancer who were married at the time of diagnosis live markedly
longer compared with unmarried patients, U.S. researchers say.
In fact for some cancers, being married might be a more potent factor for cancer
survival than chemotherapy, the study found.
Lead study author Dr. Ayal Aizer, a chief resident in radiation oncology at
Harvard Medical School in Boston, said married patients were also more likely to
be diagnosed with earlier-stage disease and much more likely to receive the
The study was the first to show a consistent and significant benefit of marriage
on survival among each of the 10 leading causes of cancer-related death in the
United States -- lung, colorectal, breast, pancreatic, prostate, liver/bile
duct, non-Hodgkin lymphoma, head and neck, ovarian and esophageal cancer, Aizer
For patients with prostate, breast, colorectal, esophageal and head and neck
cancers, marriage was associated with a survival increase that was larger than
that of standard chemotherapy regimens for those diseases.
The study assessed clinical and demographic data from the National Cancer
Institute's SEER database on 734,889 patients diagnosed from 2004-08.
The analysis, published in The Journal of Clinical Oncology, showed, overall,
patients who were married were 17 percent less likely to have metastatic disease
when first diagnosed with cancer compared with patients who were not married.
In addition, married patients with non-metastatic disease were 53 percent more
likely to receive therapy indicated for their disease compared with unmarried
patients and at any given time. Finally, at any given time, a patient who was
married was 20 percent more likely to be alive than a patient who was not
married, the study said.
"Marriage probably improves outcomes among patients with cancer through
increased social support," Aizer said in a statement.
"Our results suggest that patients who are not married should reach out to
friends, cancer support or faith-based groups, and their doctors to obtain
adequate social support."
