This article addresses the prescription of Chinese herbs for a radiation patient. Chinese Medicine includes acupuncture, qi gong, tai qi, massage and diet therapies, all of which are of great value to a cancer patient.
Radiation therapy can injure surrounding healthy tissue, damage fragile mucosal barriers in the lungs and intestines, injure salivary production, cause digestive problems, dryness, inflammation and even scorching depending on location, intensity and duration of the treatment. Radiotherapy can also injure the bone marrow. While the targeting of radiation therapy has vastly improved to protect surrounding tissue, radiation therapy is still a significant challenge.
From a Chinese Medicine perspective the heat from radiotherapy that is intense enough to destroy tissue generates a "toxic heat". Cancer is itself a toxin. Radiotherapy is a toxin to fight a toxin.
Herbs that rebalance the body can prevent side effects of radiotherapy, restore health and vitality, and prevent relapse and metastasis. Rebalancing is a concept of Chinese Medicine that is a fabulous complement to the cure seeking of Western Medicine.
Rebalancing against radiation toxicity is done along a continuum of signs and symptoms. For example, toxic heat depletes the moistening properties of the blood and injures the mechanisms of energy production. Then the body, in an effort to compensate for the heat, dryness and depletion of fluids, produces phlegm as a substitute lubricant. This phlegm, when combined with heat, can injure the elimination pathways in the bladder and large intestine, stagnate and deplete the blood and cause further weakness. At late stages the vital essence is injured and there is very poor energy production and compensation. Applying Chinese Medicine diagnostic principles and appropriate treatment at each stage is a way to prevent this degeneration and many side-effects.
Research has also shown that Chinese herbs improve the sensitivity of the tumor to radiotherapy. A tumor's sensitivity to radiation is in part dependent on blood supply and oxygenation of the tissues. Herbs can improve both. It is reported that tumors have a ratio of anoxic cells which have poor radiation sensitivity. Radiation therapy may reach only about 1/3 of cells with a low oxygenic state. Low tumor infiltration by radiation is considered one of the factors causing cancer relapse.
The following studies demonstrate the value of Chinese Herbal Medicine (CHM) in conjuction with radiotherapy (RT) to improve survival rates, lessen the impact of depletion of white blood cells, and improve the ability to finish the full course of treatment.
This study from Chinese Academy of Medical Sciences included 197 nasopharyngeal cancer patients who were treated with Chinese herbs plus radiation therapy compared to radiotherapy alone. The combined therapy group had twice the number of patients survive to five or more years than the radiotherapy alone group. The tumor was killed in more patients in the combined therapy group and the remote metastatic rate was less in the combined group. These findings imply that Chinese herbal medicine could enhance the radiosensitivity of tumors. (2)
| 1 year | 3 Years | 5 years | |
| CHM + RT | 91.3% | 67.4% | 52.4% |
| RT | 80% | 33.3% | 24% |
| CHM + RT | 95.7% |
| RT | 88.6% |
| CHM + RT | 34.8% |
| RT | 52.4% |
The results showed 84.5% were able to finish the full course of radiotherapy versus 63.3% in the control group. The type and staging of the cancer was not revealed.(3)
In another small study, white blood cell counts did not go as low in a combined treated group as they did with radiotherapy alone. One particular formula Fu Zheng Xiao Formula (FZZX), was shown to moderate T-lymphocyte subset. (4)
Another combined herb-radiation study was conducted with nasopharyngeal cancer patients who continued taking herbs for 6 months after the radiation was finished. The 5 year survival rate was 75%. The authors indicate that Chinese medicine combined with radiation improved the effectiveness of radiation therapy while minimizing its toxicity in both the short and long term. In this study there was no mention of a control group. (5)
Many studies, repeatedly show that Chinese herbal medicine formulas can be combined efficaciously and safely to improve life expectancy and prevent adverse side effects of radiation treatment. Herbs should be started 1 week before starting radiotherapy and continue for at least 6 months after treatment to achieve maximum benefit.
