Chemotherapy and Chemo-Support

The purpose of treating cancer cells with chemotherapy is to prevent them from dividing, invading and metastasizing. Most chemotherapeutic agents exert their effect on cell multiplication: obviously since multiplication is a characteristic of many normal cells, chemotherapeutic agents will inevitably affect also normal cells and especially those with a rapid rate of multiplication and turnover such as those of the hair, intestinal mucosa, blood and bone marrow. This explains the common toxic effect of chemotherapy on the hair, the intestines (vomiting and diarrhoea), the blood (affecting blood counts) and bone marrow (affecting the immune system).

Inhibition of cell multiplication can take place at several levels within the cell:

  • Macromolecular synthesis and function

  • Cytoplasmic organization

  • Cell membrane synthesis function

  • Environment of cancer cell growth

Most agents have their primary effect on either macromolecular synthesis or function. They interfere with the synthesis of DNA, RNA or proteins or with the appropriate functioning of the molecule. When interference with macromolecular synthesis or function of the neoplastic cells is sufficiently great, a proportion of the cells die. Because only a proportion of the cells die as a result of a given treatment, repeated doses of chemotherapy must be used to continue to reduce their number.

Neoplastic cell death may not take place at the time of exposure to the chemotherapeutic agent. Often the cell must undergo several divisions before the lethal event that took place earlier results in death of the cell. This means that the effect of chemotherapy may last for several weeks after the end of the treatment: likewise with its toxic effects on normal cells. This has important implication for our protocols as it means that we need to continue tonifying Qi and Blood for some time after the end of the treatment.


The toxicity of chemotherapeutic agents (and also of other drugs) is not a fixed entity but it varies according to several factors:

  • Toxicity of specific agent
  • Dose
  • Schedule of administration
  • Route of administration
  • Predisposing factors of the patient which may be known or unknown before the start of the treatment
  • Sex (women tend to develop toxicity at a lower dose than men)

Common Toxicities

Some toxicities are relatively common among chemotherapeutic agents. Common acute toxicities include:

  • Myelo-suppression with leukopenia, thrombocytopenia and anaemia.
  • Nausea and vomiting
  • Mucous membrane ulceration
  • Alopecia

Apart from nausea and vomiting, these toxicities occur because of the cytotoxic effect of chemotherapy on rapidly-dividing normal cells in the bone marrow, mucous membranes and hair.

The side-effects of chemotherapy vary greatly according to the agent used. Agents may be broadly classified into four groups:

  • Alkylating agents damage the programs that control growth in the chromosomes of the tumour cells. Example: busulfan, carboplatin, carmustine, chlorambucil, cisplatin, cyclophosphamide, dacarbazine, doxorubicin, estramustine, ifosfamide, lomustine, mechlorethamine, melphalan, semustine, thiotepa.

  • Antimetabolites interfere with the manufacture of nucleotides, the substances that make up the DNA. Example: azacitidine, capecitabin, cladribine, floxuridine, fludarabine, 5-fluorouracil, gemcitabine, mercaptopurine, methotrexate, pentostatin, raltitrexed, thioguanine, trimetrexate.

  • Natural products interfere with cell structure and cell division. Example: asparaginase, bleomycin, dactinomycin, daunorubicin, docetaxel, doxorubicin, epirubicin, etoposide, idarubicin, irinotecan, plicamycin, mitomycin, mitoxantrone, taxol, teniposide, topotecan, vincristine, vinblastine.

  • Hormones block the effect of oestrogen by acting on the oestrogen-receptors. Example: aminoglutethimide, anastrozole, bicalutamide, dexamethasone, diethylstilbestrol, fluoxymesterone, flutamide, goserelin, leuprolide, letrezole, nilutamide, raloxifen, tamoxifen, torenufen.

  • Miscellaneous agents: altretamine, amifostine, amsacrine, dexrazoxane, hydroxyurea, mitotane, pamidronate, porfimer, procarbazine.

  • Biologic agents
    Monoclonal antibodies: rituximab, trastuzumab.
    Interferons: interferon-ÿ2a and interferon-ÿ2b.
    Interleukins: aldesleukin, oprelvekin.
    Myeloid- and erythroid-stimulating factors: erythropoietin, filgrastim, sargramostim.

Short Term Side Effects of Cytotoxic Drugs

Short-term side-effects of cytotoxic drugs include:

  • Loss of appetite
  • Nausea
  • Vomiting
  • Stomatitis
  • Malaise
  • Flu-like feeling, fever
  • Cystitis
  • Haematuria
  • Constipation
  • Diarrhoea

Long Term Side Effects of Cytotoxic Drugs

Long-term side-effects of cytotoxic drugs include:

  • Cardiac toxicity (usually from high doses of doxorubicin or daunorubicin). Doxorubicin is widely used for breast carcinoma. If radiation is administered to the chest, the cardiac toxicity (in the form of congestive cardiac failure) may occur at lower doses. This particular long-term side-effect may occur even several years after the administration of chemotherapy.
  • Pulmonary toxicity (pulmonary fibrosis) is associated with high doses of bleomycin but also with alkylating agents and methotrexate.
  • Haematologic impairment. Alkylating agents may cause cytopenia.
  • Immunologic impairment and myelo-suppression. Fludarabine, cladribine and pentostatin cause profound suppression of CD4 and CD8 lymphocytes and render patients treated susceptible to opportunistic infections. There may be a fall in white blood cells and platelets counts.
  • Skin reactions (rash, inflammation, pigmentation, photosensitivity)
  • Liver toxicity.
  • Nephrotoxicity. This is typically caused by cisplatin, oxaliplatin, methotrexate and nitrosoureas). This toxicity may be acute or chronic and in severe cases it may require haemodialysis.
  • Neurotoxicity (peripheral neuropathy) is typically caused by vinca alkaloids, cisplatin, oxaliplatin, epipodophyllotoxins and paclitaxel.
  • CNS toxicity (lethargy, fatigue, depression, headaches, poor memory and concentration)
  • Premature menopause may occur in women who have received certain chemotherapeutic agents such as alkylating agents or procarbazine.

Chemotherapy Side Effects from the Point of View of Chinese Medicine

If we analyze the above side-effects, there are important differences between various cytotoxic drugs and one could conceivably formulate an individual Chinese herbal formula for each. However, one can identify common characteristics among the above side-effects. We can attempt to group the side-effects according to the Chinese pathological pattern induced by the various cytotoxic drugs. Looking at the side-effects of each drug, four patterns in particular stand out:

Hair loss, diarrhoea, nail ridging, bone-marrow suppression, malaise, fatigue, depression, loss of appetite, neurological damage, dizziness, constipation, numbness, tingling, paraesthesia of hands and feet.

Nausea, vomiting.

Mouth ulcers, stomatitis, stomach ulcers.

Haematuria, fever, skin reactions, cystitis.

Thus, we can deduce from the analysis of the above patterns that cytotoxic drugs cause the following:
1. Qi, Blood and Yin deficiency (of Stomach, Lungs, Liver and Kidneys)
2. Stomach-Qi rebelling upwards
3. Stomach Heat
4. Blood Heat.

The treatment principles to adopt are therefore (the herbs used are indicated in brackets):

  • Tonify Qi, Blood and Yin (Huang Qi Radix Astragali membranacei, Dang Shen Radix Codonopsis pilosulae, Tai Zi Shen Radix Pseudostellariae, Ling Zhi Fructificatio Ganodermae lucidi, Shan Yao Radix Dioscoreae oppositae, Xi Yang Shen Radix Panacis quinquefolii, Mai Men Dong Tuber Ophiopogonis japonici, Dang Gui Radix Angelicae sinensis, Nu Zhen Zi Fructus Ligustri lucidi, Huang Jing Rhizoma Polygonati)
  • Subdue rebellious Stomach-Qi (Lu Gen Rhizoma Phragmitis communis, Ban Xia Rhizoma Pinelliae ternatae)
  • Clear Stomach Heat (Lu Gen Rhizoma Phragmitis communis)
  • Cool Blood (Mu Dan Pi Cortex Moutan radicis)

Pharmacology of Chemo-Support Ingredients

I shall report only the pharmacology of the above plants that is relevant to chemotherapy, immune function, inflammation, digestion or carcinoma. Thus, for each plant, there are many other pharmacological actions not reported below. These data are not available for all of Chemo-Support's ingredients.
It should also be noted that such data are reported for reference only as they reflect a reductionist view of the action of herbs that is at variance with the Chinese medicine view. Some of the research studies reported present a doubly-reductionist view: firstly, they use single herbs and secondly, many of them use single constituents of a herb. By contrast, Chinese medicine uses only formulae composed of several herbs. It is a well-know fact that first of all, the action of a herb is more than the sum-total of the actions of its individual constituents and secondly, the synergistic action of a formula is more than the sum total of its individual herbs.
Furthermore, many of the studies reported are based on animal experiments which could be criticized on ethical grounds.

Radix Astragali membranacei
2'4'-dihydroxy-5,6-dimethoxyisoflavone, kumatakenin, choline, betaine, polysaccharides, glucoronic acid, folic acid.
1. Enhancement of immune function
The decoction given to mice increased the phagocytic activity of the reticuloendothelial system. Oral administration or nasal spray of Huang Qi offered protection against the common cold. Intraperitoneal administration of the polysaccharides from the root of Astragalus membranaceus antagonized the atrophy of immune tissues such as spleen, thymus and intestinal lymph nodes as well as leukopenia caused by immunosuppressant prednisolone in mice. Intraperitoneal administration of the homogeneous fraction of the polysaccharides astragalan I and II increased the weight and cell number of mouse spleen. Two months of oral treatment with the herb in subjects susceptible to common cold greatly increased the levels of SIgA and IgG in the nasal secretion.
2. Antibacterial effect
In vitro, Huang Qi was effective against Shigella shigae, Bacillum anthracis, Streptococcus hemolyticus, Corynebacterium diphtheriae, Diplococcus pneumoniae, Staphyloccus aureus.
3. Prevention of renal toxicity in chemotherapy
A double-blind trial of 49 patients undergoing chemotherapy showed that the decoction of Huang Qi Radix Astragali membranacei and Fu Ling Sclerotium Poriae cocos markedly reduced the incidence of renal toxicity. Rats with experimentally-induced glomerulonephritis, when treated with Huang Qi had significantly less proteinuria than control groups as well as milder pathological tissue changes.
4. Effect on endurance
Decoction of Huang Qi given to mice significantly increased their endurance in swimming tests.
5. Endocrine effect in patients undergoing radiotherapy
In a randomized clinical trial, the plasma hydrocortisone level in stage II carcinoma of the cervix was observed. The average level in 18 patients before and after irradiation were 8.0 and 6.1 µg/100ml, whereas the before and after levels were 9.5 and 9.1 µg/100ml in patients who received a decoction of Huang Qi Radix Astragali membranacei and Nu Zhen Zi Fructus Ligustri lucidi for two months.
6. Anti-inflammatory effect
Intravenous dose of 5 mg/Kg or oral dose of 50 mg/Kg of astramembranin I inhibited the increase in vascular permeability induced by serotonin or histamine in rats.
7. Hepatoprotective effect
Intravenous administration of 10 mg/Kg of astramembranin I induced accumulation of cAMP in rabbit plasma.

Radix Codonopsis pilosulae
Saponins, trace of alkaloids, carbohydrates, mucilage, resin, volatile oil, scutellarein glucoside, polysaccharides.
1. Promotion of phagocytosis
Daily administration of decoction enhanced reticuloendothelial phagocytosis.
2. Protection from chemotherapy side-effects
A double-blind clinical trial of 16 patients with lung cancer undergoing chemotherapy showed that the extract of Dang Shen Radix Codonopsis pilosulae and Mai Men Dong Tuber Ophiopogonis japonici significantly reduced the incidence of side-effects from chemotherapy.
3. Haematologic effect
Oral and intravenous use of Dang Shen in normal rabbits caused an increase in red blood cells count and haemoglobin.
4. Immunologic effect
Dang Shen inhibited the febrile reaction to toxins such as turpentine in mice and rats.
5. CNS effect
Preparations of Dang Shen given to mice caused a general stimulatory response. A 20% ethanolic extract of the root improved memory capacity in experimental-compromised mice and rats subjected to a step-down test after oral administration of 30-60 g/Kg for 3 days.
6. Endocrine effect
Plasma corticosterone level in mice was elevated after oral, intraperitoneal or subcutaneous administration of the decoction. Reductions of corticosterone level after treatment with dexamethasone were decreased after administration of the n-butanolic fraction of the decoction, suggesting effects at the pituitary or superior central structures.
7. Anti-stress effect
Oral administration of the decoction of the root prolonged the life span of mice under conditions of limited oxygen supply.
8. Anti-ulcerative effect
Pre-treatment with the decoction of the herb reduced the incidence of ulcers in rats due to stress of pylorus ligation.

Fructificatio Ganodermae lucidi

1. Cardiotonic action. The tincture had a significant cardiotonic action on the isolated frog heart.
2. Action on coronary circulation. Injection of an extract given to dogs rapidly increased the coronary flow by 44%.
3. Regulation of immune function and inhibition of allergic reaction. Ling Zhi accelerated the clearance of I-labelled protein in the blood of albino mice, indicating its ability to enhance the phagocytic action of the reticuloendothelial system. The polysaccharide fraction of Ling Zhi markedly increased the phagocytic ability of abdominal macrophages of mice against chicken erythrocytes. These facts suggest that the polysaccharides can increase non-specific immunologic function of the body.

1. Incremental effect on white blood cells
The fruit increased white blood cells in leukopoenia due to chemotherapy or radiotherapy in mice.
2. Effect on immune function
The fruit promoted lymphoblast transformation and increased the number of cells with haemolytic plaques. The in vitro restorative effect of the aqueous extract of the herb was studied in cancer patients and in normal healthy donors. Using the local graft versus host (GvH) reaction as a test assay for T-cell function, the extract affected an immune restoration in 9 of 13 cancer patients with an increase in local GvH reaction from 32.3 / 36.1 mm3 to 118/ 104.9 mm3; these results suggest the herb contains powerful immune stimulants.
3. Antineoplastic action
The extract given by intragastric administration to mice gave a 49% inhibition rate against cervical cancer. The extract of the herb has been found to reverse tumour-associated macrophage suppression; these data suggest that the herb has cancer chemopreventive properties.
4. Effect on leukopenia
The injection of an extract of the fruit given once or twice daily could be used in cancer patients to prevent and treat leukopenia caused by chemotherapy.
5. Anti-inflammatory effect
Paw oedema in rats was inhibited by oral administration of 12.5 or 25 g+Kg of the decoction of the herb for 5 days.

1. Glucocorticoid-like action
Injection of glycyrrhizin in healthy subjects increased free cortisol levels in the blood. Intraperitoneal administration of a low dose of glycyrrhizin to rats caused atrophy of the thymus gland and increased weight of the adrenal gland suggesting a cortico-tropin-like action; in patients with mild Addison's disease requiring daily intramuscular injection of 12.5 mg of cortisone, concurrent daily intramuscular dose of glycyrrhizin increased urinary free 17-hydroxycorticosterone and decreased the conjugated 17-hydroxycorticosterone.
2. Mineralocorticoid-like action
The extract reduced the urinary volume and sodium excretion and increased potassium excretion in various animal species.
3. Anti-inflammatory action
The anti-inflammatory effect of the herb resembles that of butazone or hydrocortisone; cotton pledget-induced granulation, formaldehyde induced paw swelling and subcutaneous granulomatous inflammation in rats were all inhibited by glycyrrhetic acid.
4. Effect on the immune system
Glycyrrhizin inhibited egg-white-induced allergic reaction in guinea pigs. Glycyrrhizin inhibited the degranulation of mast cells elicited by the histamine liberation agent, Compound 48/80, so that it suppressed the release of the allergy mediators.
5. Anti-ulcer action
Injection of the herb extract produced significant inhibition of ulcers in albino rats, together with marked reduction in gastric juice and free acid. In many clinical studies on the use of Gan Cao for ulcers, the effectiveness was usually around 90%.
6. Anti-neoplastic action
Glycyrrhetinic acid inhibited the transplanted Oberling-Guerin myeloma in rats.
7. Effect on lipid metabolism
In rats with atherosclerosis, Gan Cao lowered cholesterol levels and stopped the progression of the lesions.
8. Antihepatotoxic effect
Oral administration of the extract of the herb showed hepatoprotective effects against carbon tetrachloride-induced cytotoxicity in rats; it markedly abated hepatic degeneration and necrosis, promoted the recovery of hepatocellular glycogen and ribonucleic acid and also lowered serum glutamic pyruvic transaminase. Glycyrrhizin and glycyrrhetic acid are able to prevent the development of cirrhosis.

Dosage and Protocol

Chemo-Support works better if it is started some time before the beginning of chemotherapy and continued for about two weeks after the end. It is important to note that "during the treatment" means during the course of treatment, i.e. also in the days of break from the treatment. The dosage is as follows:

  • Two weeks before start of treatment: 2 tablets twice a day
  • Four days before the start of treatment: 2 tablets three times a day
  • During the treatment: 3-4 tablets three times a day
  • After the end of the treatment for about 2 weeks: 2 tablets three times a day

It is best to take the tablets away from meals, i.e. about 1 hours before or after a meal, swallowed with hot water. The tablets should also be taken separately from other medication, at least 1 hour away. If the patient feels very nauseous and finds it difficult to swallow the tablets, these could be crushed and powdered, immersed in a small amount of hot water and the water sipped slowly.
The dosage during treatment indicated above should be adjusted according to the severity of the side-effects and the above dosage could be reduced or increased.
If the patient is receiving both chemo- and radio-therapy and is taking both Chemo-Support and Radio-Support, the dosage of each should be reduced. Adjustments can be made according to the patient's side-effects and timing of therapies in this situation by using a higher ratio of Chemo-Support during the days surrounding chemotherapy or when its side-effects are heightened. Similarly, the dosage of Radio Support can be increased if the side-effects experienced from radiotherapy are more severe, or during the days surrounding the administration of radiotherapy.
Chemo-Support should be discontinued approximately two weeks after the end of the treatment when the condition should be reassessed and a different remedy given. By contrast, Radio-Support should be continued for at least 6 weeks after the end of radtiotherapy.

Acupunture Treatment of Chem-Support Side Effects

Acupuncture can be used to great effect, in conjunction with Chemo Support to reduce the side-effects of chemotherapy. Indeed, acupuncture can complement the use of Chemo-Support by tailoring the treatment to the specific side-effects suffered by the patient. The following are suggested point combinations for specific symptoms and signs.

Ren-12 Zhongwan, ST-36 Zusanli, SP-6 Sanyinjiao, BL-20 Pishu, BL-21 Weishu.

Nausea, vomiting
Ren-13 Shangwan, P-6 Neiguan, ST-34 Liangqiu, ST-36 Zusanli. In addition to acupuncture, the following massage technique is very effective to combat nausea and vomiting: apply a massage oil liberally to the lower legs, make a loose fist with your hands, starting from ST 36, massage downwards along the Stomach channel using the knuckle of the index fingers all the way down to the ankle and then massage upwards along the Spleen channel using your thumbs. This technique harmonizes the ascending and descending of Stomach- and Spleen-Qi, stimulating Stomach-Qi to descend and Spleen-Qi to ascend.
