Obesity and cancer

Article

Two studies on obesity and cancer released results this week. One study showed leukemia cells finding a safe haven in the fat tissue of obese mice, and the other study predicts that obesity could be the leading cause of cancer in women in the future. The leukemia study, published online by Cancer Research, was inspired by an earlier study which showed that obese children have a 50 percent higher chance of recurrence of acute lymphoblastic leukemia than lean children. Researchers developed obese mice with leukemia and treated the mice with traditional chemotherapy used in children. Compared with the normal mice with leukemia, the obese mice had a higher relapse rate. Upon closer examination of the relapsed mice, researchers found leukemia cells hiding in the fat tissue, protected from the chemotherapy. This may explain why obese people often have poorer prognoses in not only leukemia but other cancers as well.In the second study, European researchers found cancer could be attributed to obesity in about 124,000 cases in 2008. In men, 3.2 percent of cancers were caused by obesity, but in women the number was higher at 8.6 percent. These findings were announced at a joint meeting of the European Cancer Organization and the European Society for Medical Oncology where lead researcher Andrew Renehan, MD, said, "As more people stop smoking and fewer women take hormone replacement therapy, it is possible that obesity may become the biggest attributable cause of cancer in women in the next decade." These studies and other research will hopefully help us understand the connection between obesity and certain cancers and will encourage more patients, survivors, and health care providers to make losing weight not just a suggestion but a prescription for fighting cancer.

For patients with cancer, the ongoing chemotherapy shortage may cause some anxiety as they wonder how they will receive their drugs. However, measuring drugs “down to the minutiae of the milligrams” helped patients receive the drugs they needed, said Alison Tray. Tray is an advanced oncology certified nurse practitioner and current vice president of ambulatory operations at Rutgers Cancer Institute in New Jersey.  If patients are concerned about getting their cancer drugs, Tray noted that having “an open conversation” between patients and providers is key.  “As a provider and a nurse myself, having that conversation, that reassurance and sharing the information is a two-way conversation,” she said. “So just knowing that we're taking care of you, we're going to make sure that you receive the care that you need is the key takeaway.” In June 2023, many patients were unable to receive certain chemotherapy drugs, such as carboplatin and cisplatin because of an ongoing shortage. By October 2023, experts saw an improvement, although the “ongoing crisis” remained.

Transcript: Particularly at Hartford HealthCare, when we established this infrastructure, our goal was to make sure that every patient would get the treatment that they need and require, utilizing the data that we have from ASCO guidelines to ensure that we're getting the optimal high-quality standard of care in a timely fashion that we didn't have to delay therapies. So, we were able to do that by going down to the minutiae of the milligrams on hand, particularly when we had a lot of critical drug shortages. So it was really creating that process to really ensure that every patient would get the treatment that they needed.
