The study uncovers a link between being married and living longer among cancer patients, with the beneficial effect of marriage differing by race/ethnicity and place of birth, researchers said.
Researchers from the Cancer Prevention Institute of California, and University of California, San Diego, assessed information on nearly 800,000 adults in California who were diagnosed in 2000 to 2009 with invasive cancer and were followed through 2012.
They found that unmarried cancer patients had higher death rates than married patients.
These patterns were minimally explained by greater economic resources among married patients, including having private health insurance and living in higher socioeconomic status neighborhoods.
The beneficial effect of being married on survival differed across racial/ethnic groups.
Among men and women, whites benefitted the most from being married while Hispanics and Asian/Pacific Islanders benefitted less, researchers said.
Also, Hispanic and Asian/Pacific Islander cancer patients who were born in the US experienced a greater benefit than those born outside the country.
The findings indicate that physicians and other health professionals who treat unmarried cancer patients should ask if there is someone within their social network available to help them physically and emotionally.
"Research is needed to understand the specific reasons behind these associations so that future unmarried patients can receive interventions to increase their chances of survival," said Maria Elena Martinez, of the University of California, San Diego.
