Success of Cancer Treatment May Depend on Social Interactions

New research suggests social interactions during a course of chemotherapy influences the success of the treatment.

Investigators from the National Institutes of Health and the University of Oxford discovered cancer patients were a little more likely to survive for five years or more after chemotherapy if they interacted during chemotherapy with other patients who also survived for five years or more.

Patients were a little more likely to die in less than five years after chemotherapy when they interacted during chemotherapy with those who died in less than five years.

The findings appear online in the journal Network Science.

“People model behavior based on what’s around them,” said Jeff Lienert, lead author from the NHI’s National Human Genome Research Institute (NHGRI).

“For example, you will often eat more when you’re dining with friends, even if you can’t see what they’re eating. When you’re bicycling, you will often perform better when you’re cycling with others, regardless of their performance.”

Lienert set out to see if the impact of social interaction extended to cancer patients undergoing chemotherapy. Joining this research effort were Lienert’s adviser, Felix Reed-Tsochas, Ph.D., Laura Koehly, Ph.D., and Christopher Marcum, Ph.D.

They based their findings on electronic medical records data from 2000 to 20009 from two major hospitals in the United Kingdom’s National Health Service.

The researchers examined the total time a patient spent with the same patients undergoing chemotherapy and their five-year survival rate. The five-year survival rate is the percentage of people who live at least five years after chemotherapy treatment is completed.

For example, a five-year survival rate of 70 percent means that an estimated 70 out of 100 people are still alive five years after chemotherapy. They also reviewed a room schematic to confirm the assumption that patients were potentially positioned to interact.

“We had information on when patients checked in and out of the chemotherapy ward, a small intimate space where people could see and interact for a long period of time,” Lienert said. “We used ‘time spent getting chemotherapy in a room with others’ as a proxy for social connection.”

When patients were around those during chemotherapy who died in less than five years following chemotherapy, they had a 72 percent chance of dying within five years following their chemotherapy.

The best outcome was when patients interacted with someone who survived for five years or longer: They had a 68 percent chance of dying within five years. The researchers’ model also predicted that if patients were isolated from other patients, they would have a 69.5 percent chance of dying within five years.

“A two percent difference in survival — between being isolated during treatment and being with other patients — might not sound like a lot, but it’s pretty substantial,” Lienert said.

“If you saw 5,000 patients in nine years, that two percent improvement would affect 100 people.”

“Mr. Lienert’s research is the first to investigate, on a large scale, how social context in a treatment setting can play a significant role in disease outcomes,” said Koehly.

“As cancer care moves more towards targeted therapies based on genomic tumor assessments, NHGRI is interested in understanding how these social environmental factors might impact treatment efficacy.”

The researchers didn’t study why the difference occurred, but hypothesize that it may be related to stress response. “When you’re stressed, stress hormones such as adrenaline are released, resulting in a fight or flight response,” Lienert said.

“If you are then unable to fight or fly, such as in chemotherapy, these hormones can build up.”

While the researchers also didn’t investigate the impact of visitors on cancer patients undergoing therapy, the effect would likely be similar, he said.

“Positive social support during the exact moments of greatest stress is crucial,” Lienert said.

“If you have a friend with cancer, keeping him or her company during chemotherapy probably will help reduce their stress. The impact is likely to be as effective, and possibly more effective, than cancer patients interacting with other cancer patients.”
