Study: Fish Oil Fights Weight Loss Caused by Chemotherapy

In this study, researchers compared 16 lung cancer patients who took fish oil to 24 patients who didn't. Muscle mass and fat tissue were monitored by CT scan periodically during initial chemotherapy cycle lasting about 10 weeks. Patients taking fish oil maintained their weight, while those who did not take fish oil lost an average of about 5 lbs., most of which was muscle mass.

The main ingredient in fish oil -- omega-3 fatty acids -- is thought to decrease inflammation in the body.

Critics of the study note that patients and researchers knew who took fish oil, so the effects could have been influenced by patient expectations.

Cold Cap Therapy May Help Women Undergoing Chemotherapy Keep Hair

Photo Courtesy - ABC News(NEW YORK) -- When Shirley Billigmeier was diagnosed with breast cancer this spring, she was grateful for a good prognosis and set about preparing for the life disruption that comes with undergoing a lumpectomy, radiation and chemotherapy.

"I just had a feeling that I was just going to be sick this whole time," said Billigmeier. "And my concern was that it was just gonna absolutely take me out of my life for a while."

When her doctor told her that total hair loss was an inevitable side effect of the chemotherapy, she braced herself and bought a wig, but then a friend told her about another breast cancer patient who managed to preserve her hair using a little-known approach that involves keeping the scalp very cold during chemotherapy treatments.

Billigmeier tracked down the makers of Penguin Cold Caps, designed to help chemotherapy patients keep their hair.

"[He] gives me a list of probably 10 women," said Billigmeier. "I start calling and start having some great conversations with lots of women across the United States. And the women I was talking to, they kept their hair."

Her Minneapolis oncologist, Dr. Paul Zander, was skeptical at first. He knew that early experiments in the United States in the 1980s hadn't been very promising. Still, he gave her the okay to try it. So, each day she received chemotherapy, Billigmeier put on a freshly chilled cap chilled to minus-22 degrees Fahrenheit every 30 minutes for seven hours.

But would it work? After her sixth and final treatment, Billigmeier's locks were intact.

"My hair is all there," she said. "It definitely works."

No one knows how it works. One theory is the caps may decrease blood flow to the scalp, causing the blood vessels in the scalp to shrink. This, in turn, blocks the harsh chemicals in the chemotherapy from reaching the hair follicles. But the fact is no one knows exactly why some women keep their hair after using the caps.

Some doctors are worried by the lack of data on cold caps and fear the treatment may even do more harm than good, for some patients. Still, cold caps are experiencing a groundswell of support from a growing number of women receiving chemotherapy who say it works -- and spread the news.

While early trials with scalp cooling showed it often was ineffective, an analysis of 53 studies showed that since 1995 research suggests the scalp cooling preserves hair in about 70 percent of patients.

But a number of doctors told ABC News they don't support the approach because of another concern.

"I don't know how well this was substantiated, but there has been concern that by blocking chemotherapy from reaching the area of the hair follicles there would be an increase in metastases of the scalp," said Dr. Mary Daly, an oncologist at the Fox Chase Cancer Center in Philadelphia.

Since there are no substantial longitudinal studies measuring such a risk, many doctors strongly discourage using the caps.
