The chemotherapy drug cisplatin may cause excessive loss of magnesium and potassium in the urine. Preliminary reports suggest that both potassium and magnesium supplementation may be necessary to increase low potassium levels. Severe magnesium deficiency caused by cisplatin therapy has been reported to result in seizures. Severe magnesium deficiency is a potentially dangerous medical condition that should only be treated by a doctor. People receiving cisplatin chemotherapy should ask their prescribing doctor to closely monitor magnesium and potassium status.

A modified form of vitamin A has been reported to work synergistically with chemotherapy in test tube research. Vitamin C appears to increase the effectiveness of chemotherapy in animals and with human breast cancer cells in test tube research. In a double-blind study, Japanese researchers found that the combination of vitamin E, vitamin C, and N-acetyl cysteine (NAC)—all antioxidants—protected against chemotherapy-induced heart damage without interfering with the action of the chemotherapy.

A comprehensive review of antioxidants and chemotherapy leaves open the question of whether supplemental antioxidants definitely help people with chemotherapy side effects, but it clearly shows that antioxidants need not be avoided for fear that the actions of chemotherapy are interfered with. Although research remains incomplete, the idea that people taking chemotherapy should avoid antioxidants is not supported by scientific research.

Patients with inoperable head and neck cancer were treated with a spleen peptide preparation (Polyerga) in a double-blind trial during chemotherapy with cisplatin and 5-FU. The spleen preparation had a significant stabilizing effect on certain white blood cells. People taking it also experienced stabilized body weight and a reduction in the fatigue and inertia that usually accompany this combination of chemotherapy agents.

Taurine has been shown to be depleted in people taking chemotherapy. It remains unclear how important this effect is or if people taking chemotherapy should take taurine supplements.

Gamma-linolenic acid (GLA), found in evening primrose and borage oils, may enhance the therapeutic effects of tamoxifen. A small group of breast cancer patients took 2.8 g of oral GLA per day in addition to tamoxifen, in a preliminary trial. Another group of breast cancer patients took tamoxifen alone. Those taking the GLA-tamoxifen combination appeared to have a better clinical response than did those taking tamoxifen alone. However, the results of this preliminary research are far from conclusive and need to be confirmed in a larger, more definitive trial.

In preliminary research, large amounts of melatonin were used successfully in combination with tamoxifen in a few people with breast cancer for whom tamoxifen had previously failed. The amounts used in this study should be taken only under the supervision of a doctor.

Milk thistle’s (Silybum marianum) major flavonoids, known collectively as silymarin, have shown synergistic actions with the chemotherapy drugs cisplatin and doxorubicin (Adriamycin) in test tubes. Silymarin also offsets the kidney toxicity of cisplatin in animals. Silymarin has not yet been studied in humans treated with cisplatin. There is some evidence that silymarin may not interfere with some chemotherapy in humans with cancer.

Peptides or short proteins derived from the thymus gland, an important immune organ, have been used in conjunction with chemotherapy drugs for people with cancer. One study using thymosin fraction V in combination with chemotherapy, compared with chemotherapy alone, found significantly longer survival times in the thymosin fraction V group. A related substance, thymostimulin, decreased some side effects of chemotherapy and increased survival time compared with chemotherapy alone. A third product, thymic extract TP1, was shown to improve immune function in people treated with chemotherapy compared with effects of chemotherapy alone. Thymic peptides need to be administered by injection. People interested in their combined use with chemotherapy should consult a doctor.

Tocotrienols are compounds similar to vitamin E that are found in palm oil. Test tube studies have shown that tocotrienols enhance the effects of tamoxifen. Controlled studies are needed to determine whether supplementing with tocotrienols might enhance the anticancer effects of tamoxifen.

In a preliminary trial, taking wheat grass in the amount of 60 ml (about 2 ounces) per day during chemotherapy reduced the incidence of certain chemotherapy-related side effects (including anemia and a decline in white blood cell counts) in women with breast cancer. Taking wheat grass did not appear to interfere with the anticancer effect of the chemotherapy. The chemotherapy used in this study was a combination of 5-fluorouracil, doxorubicin, and cyclophosphamide.

In a double-blind trial, intravenous administration of calcium and magnesium before and after administration of oxaliplatin prevented the development of oxaliplatin-induced nerve damage. However, in another double-blind trial, the same treatment regimen as in the other study did not prevent oxaliplatin-induced nerve damage. It is not known whether oral administration of these minerals would also be beneficial.

Though cancer cells use glutamine as a fuel source, studies in humans have not found that glutamine stimulates growth of cancers in people taking chemotherapy. In fact, animal studies show that glutamine may actually decrease tumor growth while increasing susceptibility of cancer cells to radiation and chemotherapy, though such effects have not yet been studied in humans.

Glutamine has successfully reduced chemotherapy-induced mouth sores. In one trial, people were given 4 grams of glutamine in an oral rinse, which was swished around the mouth and then swallowed twice per day. Thirteen of fourteen people in the study had fewer days with mouth sores as a result. These excellent results have been duplicated in some, but not all double-blind research. In another study, patients receiving high-dose paclitaxel and melphalan had significantly fewer episodes of oral ulcers and bleeding when they took 6 grams of glutamine four times daily along with the chemotherapy.

One double-blind trial suggested that 6 grams of glutamine taken three times per day can decrease diarrhea caused by chemotherapy. However, other studies using higher amounts or intravenous glutamine have not reported this effect.

Intravenous use of glutamine in people undergoing bone marrow transplants, a procedure sometimes used to allow very high amounts of chemotherapy to be used, has led to reduced hospital stays, leading to a savings of over $21,000 for each patient given glutamine.

In a double-blind study, supplementation with 18 grams of glutamine per day for 15 days, starting five days before the beginning of 5-FU therapy, significantly reduced the severity of drug-induced intestinal toxicity.

High-dose cisplatin chemotherapy is associated with kidney toxicity and damage, which may be reduced by glutathione administration. Nerve damage is another frequent complication of high amounts of cisplatin. Preliminary evidence has shown that glutathione injections may protect nerve tissue during cisplatin therapy without reducing cisplatin’s anti-tumor activity. There is no evidence that glutathione taken by mouth has the same benefits.

In one human study, administration of 4,000 mcg per day of a selenium product, Seleno-Kappacarrageenan, reduced the kidney damage and white blood cell–lowering effects of the chemotherapy drug cisplatin. The amount of selenium used in this study is potentially toxic and should only be used under the supervision of a doctor. In another study, patients being treated with cisplatin and cyclophosphamide for ovarian cancer were given a multivitamin preparation, with or without 200 mcg of selenium per day. Compared with the group not receiving selenium, those receiving selenium had a smaller reduction in white blood cell count and fewer chemotherapy side effects such as nausea, hair loss, weakness, and loss of appetite.
