Leveling the Odds: How Two Duke Professors Are Giving Families in Tanzania a Better Chance of Beating Cancer

Thursday, February 8, 2018

In 2014, Kristin Schroeder, MD, MPH, then a global health fellow, was treating Japhet, an 11 year old boy, for lymphoma at the Bugando Medical Centre in Mwanza, Tanzania. Japhet’s family was deeply dedicated to pursuing a cure for his cancer, but the cost and logistics of the treatment were prohibitive. 

One day, Japhet’s father called Schroeder to tell her that he was now able to afford the treatment—he’d sold the family’s cow to save his son. 

“That conversation really hit home for me, because that cow was the family’s livelihood,” said Schroeder, now an assistant professor of pediatrics and global health at Duke. “Japhet’s parents did everything they could to get treatment for their son, but unfortunately, by the time they pulled the resources together, it was too late.” Japhet’s metastatic lymphoma took his life shortly after that conversation.

Stories like this are a stark reminder of the barriers faced by cancer patients in many parts of the world. In Tanzania, pediatric cancer treatment costs around $300—a fraction of what it would cost in the United States, but an insurmountable burden for many in a country where most families make less than $500 per year. 

Even for those who can afford treatment, travel is another obstacle. The Bugando Medical Centre (BMC) is one of only three hospitals in the country that provides oncology care, and most Tanzanians live at least six hours from a cancer treatment facility. Faced with such financial and logistical hurdles, some families are forced to abandon treatment mid-course. Others, like Japhet’s, aren’t able to marshal resources until the disease has progressed. As a result, while more than 80 percent of children in the United States now survive cancer, in Tanzania, only 20 percent do. 

But for Schroeder, who went to Tanzania with the goal of improving those outcomes, Japhet’s case was also a wake-up call. Soon after the encounter, she began working with Nelson Chao, MD, MBA, — chief of the Division of Hematologic Malignancies and Cellular Therapy and professor of medicine, immunology, pathology and global health at Duke — to find ways to help families overcome the roadblocks to cancer treatment. Chao, the director of the Duke Global Health Institute’s global cancer initiative, had been working with Schroeder to establish a research infrastructure at BMC, but the two doctors realized that to improve the odds for families like Japhet’s, they needed to address issues outside the hospital as well. 

In late 2014, they established the International Cancer Care and Research Excellence Foundation (iCCARE), a nonprofit whose mission is to give any child diagnosed with cancer the same chance of a cure regardless of where they live. Funded primarily through individual donations, iCCARE covers treatment costs for BMC pediatric cancer patients and provides other resources and support, including a hostel where they and their families can stay while receiving treatment. 

“Initially, we envisioned iCCARE just paying for the chemo, but when we tested the idea that removing this barrier would drastically improve access and outcomes, we found that it didn’t,” said Schroeder. “And as we continued our research, we started to understand all of the other factors that contribute to treatment abandonment and poor outcomes, so we’ve expanded our vision.”

New Support, New Outcomes

Part of that expanded vision has been to create new clinical positions that fill gaps revealed by Schroeder’s research. The new patient navigator’s primary role is to educate families about the cancer treatment process. She also consults with nurses and residents on other pediatric floors to identify possible cancer symptoms in children who were admitted to BMC for other reasons. Prior to hiring the patient navigator, the average time to cancer diagnosis among these patients was 49 days; now, it’s just over two weeks. 

This result is incredibly significant, Schroeder says, because “expedited diagnosis not only increases survival rate, but it also correlates with a reduction in treatment abandonment.” In part due to the success of the patient navigator program, the survival rate at BMC has increased from 19 percent to 39 percent, and the treatment abandonment rate has decreased from 47 percent to 32 percent.

iCCARE has also hired a clinical coordinator, who oversees outpatient clinic visits, communicates with patients between visits, checks patients into the clinic and helps track patient outcomes.

My job is to give medications, take vital signs, and care for the families staying here while they get treatment. We have many families from many places—from different backgrounds—all living here. I try and help the families create a sense of unity.” Photo by Izzy Pinheiro.

iCCARE’s hostel, meanwhile, provides much more than a free place to stay. Opened in 2017 in a building just a 10-minute walk from BMC, the hostel has room for eight patients and their parents, as well as a nurse, a social worker and a cook who provides two meals a day. And it’s become a community hub where patients and families find comfort through the challenges of treatment. 

“The kids hang out with each other and go to clinic together, and the parents provide support for each other,” said Schroeder. “One mom will be out at the market, while another mom is watching the children. They build this community where they’re sharing stories and experiences and learning from each other.”

Schroeder takes over the kitchen on Sunday evenings when she’s in Mwanza, where she’s based for six months of the year. She says these dinners not only give her a chance to get to know the families, but they’ve also unexpectedly enhanced her research efforts and intervention strategies.  

“We sit around and talk with families about their experience and their knowledge about their child’s cancer and treatment,” she said. “What’s been really cool is that I’ve learned so much about what parents actually understand about cancer. Through these conversations, I realized that there were some important things that we really didn’t understand and weren’t addressing properly—and it’s changed the way we approach patient and family education.”

One of these approaches is the “Wall of Cancer Education”—a wall in the hostel with pictures of symptoms and descriptions of the disease. Many of the images were created by Tanzanians, one of whom felt a particular connection to iCCARE because she’d lost a child to leukemia. 

Putting Cancer On The Air

Many of Schroeder’s patients and their families then put their newly-gained cancer knowledge to work in their communities, where lack of awareness about cancer—even among medical providers—often results in delays or prevents families from seeking treatment until it’s too late.

The fact that iCCARE is helping us brings a lot of encouragement to me.” Photo by Izzy Pinheiro.

Some former patient families have accompanied Schroeder at education sessions for local providers and talked to the doctors and nurses about their experiences. Others have taken informational brochures to distribute in their villages.

“It’s been neat to see how much knowledge the families have after going through the treatment process, and they often want to go back to their communities and share this knowledge with others,” she said.

Meanwhile, Schroeder and her colleagues from BMC are testing a pediatric cancer awareness campaign, including community talks, educational radio programming and posters, in several communities the Mwanza region. Once the campaign ends, they’ll conduct surveys to determine whether and to what extent the different approaches helped people learn about pediatric cancer. 

Their hope is that patients arrive at the hospital at earlier disease stages. “If people are more aware, they’re more likely to catch cancer early,” Schroeder noted. “Many patients come to BMC after having symptoms for months, and sometimes, that’s too late.” 

One Spoke In The Wheel

Although they’ve made extraordinary strides over the last few years, Schroeder, Chao and their Tanzanian colleagues are just getting started—and iCCARE is only part of the bigger picture. 

One of their broader goals in sustaining the steadily improving pediatric cancer outcomes is to help train a corps of local oncology providers. “We’re working with oncology colleagues in several countries to ensure that our work at Bugando isn’t just a one-time, one-place effort,” said Chao, whose work in Tanzania centers around setting up programs, cultivating partnerships and establishing a research infrastructure.

Partnerships with the Tata Medical Center in Calcutta, India, and the Uganda Cancer Institute in Kampala, Uganda, are providing oncology fellowship opportunities for Tanzanian and other East African pediatric residents. And Schroeder has taken part in training oncology residents and nurses at BMC.

They’re also working with oncology providers at the two other medical centers in Tanzania that offer pediatric cancer care to create a “Tanzanian Pediatric Oncology Team.” They plan to develop standardized protocols, increase efficiency of care and maximize resources across sites. 

It’s not easy to draw a line between where their Duke work ends and their iCCARE work begins. Ultimately, Schroeder says, they just want to provide more—and better—care to more people. 

“We have our overall aims, which are to improve pediatric cancer outcomes in Tanzania and ensure that all children with cancer have the same chance of a cure,” she said. “To do this, we need to look at the issue from many different angles—research, education and clinical care—and we’ll do what it takes to make our vision a reality.”
