A: KLT local injection at thoracic cavity can notably eliminate cancerous hydrothorax and pericardial effusion with effective rate as over 80% based on Chinese studies published. Method: After continuous drainage of hydrothorax, KLT100-200ml are combined with chemotherapy drug to be injected into local thoracic cavity once or twice per week. Meanwhile, KLT 100-200ml via intravenous dripping is applied daily with 21 days as a cycle for better therapeutic effect.
Q48. What is the mechanism behind KLT in treating hydrothorax?
A: Local injection of KLT in thoracic cavity can cause local adhesion in pleura so as to reduce exudation of hydrothorax.
Q49. What is the advantage of KLT to combine with radiation therapy?
A: 1. Enhance therapeutic effect by raising gain factor.
2. Protect hematopoiesis of bone marrow and elevate peripheral WBC.
3. Enhance immune function by activating T lymphocytes and NK cells, and
4. Improve survival quality, anorexia, loss of body weight and KPS reduction.
Q50. What is the advantage of KLT in pre-operative use?
A: KLT, in its pre-operative use, can cause liquefaction, necrosis and apoptosis of cancel cells so as to elevate surgical resection rate. In addition KLT prevents spread and metastasis of residual tumor cells by strengthening immune function of patient.
Q51. Can KLT be applied to control post-operative pulmonary infection?
A: Although KLT is not an antibiotic drug it has the function of activating T lymphocytes and NK cells to facilitate synthesis and secretion of interleukin and enhance phagocutic function of macrophage function of hematopoisis. Therefore KLT can improve immune function both specifically and nonspecifically to reduce occurrence of post-operative pulmonary infection.
Q52. What are the clinical benefits of KLT to be used by advanced cancer patients?
A: KLT is able to effectively eliminate patient cachexia state, improve life quality, increase body weight, and prolong patient life.
Q53. Can KLT notably improve patient cachexia?
A: Cancer patients at mid and advanced stages will occur cachexia with big energy consumption. KLT, as an anticancer emulsion, is able to provide high energy to patient to improve cachexia. Its calorie value is 4,906J/g, remarkably higher than that from 10% glucose or intravenous fat emulsion. Phase III study in China revealed that KLT could effectively prevent loss of body weight, increase food intake and prolong patient life. Meanwhile KLT can inhibit tumor growth, cause partial liquefaction and necrosis of tumor cells, regulate cell factor level in serum, and reduce levels of serum TNF-α and IL-1.
Q54. Which are expressed as improvement of KLT in immune function?
A: KLT can activate T-lymphocyte, NK cell and LAK cell, facilitate macrophage to synthesize and secrete interleukin, strengthen phagocutic function of macrophage and hematopoisis. Therefore KLT is able to extensively improve immune function specifically and nonspecifically.
Q55. Can KLT effectively control cancerous pain?
A: Based on phase III study in China, total effective rate of pain control among 328 cases with various tumors was 80.49% after KLT treatment. The response lasted for 1 week after withdrawal of KLT with no addiction. So KLT could partly replace morphine as an analgesic.
Q56. How long will analgesic effect of KLT last?
A: Based on phase III study in China, KLT analgesic effect appeared from 1-3 days after application and pain was gradually alleviated. 96 cases, once used morphine before the treatment, could tolerate morphine reduction and 31 cases accepted morphine withdrawal. The withdrawal rate was 32.29% (31/96).
Q57. Can KLT totally replace parenteral nutrition in treating patient with cachexia?
A: Yes. KLT provides 4,906J/g that is equivalent to 1,200 cal/g.
Q58. Can KLT applied for treating other tumors than NSCLC and primary liver cancer?
A: A large number of published clinical studies in China have proven that KLT has reliable effect in treating breast cancer, pancreatic cancer, colon-rectum cancer, prostate cancer, esophageal cancer, kidney cancer, ovarian cancer, prostate cancer, malignant lymphoma, and leukemia in addition to NSCLC and primary liver cancer.
Q59. Is KLT effective in treating tumor in brain?
A: Currently there is no published clinical study.
Q60. Could KLT be used in treating melanoma?
A: Currently there is no published clinical study to support this although oncologists in Moscow have the intention to carry out such clinical study in Russia.
Q61. What clinical benefit will KLT bring to leukemia patient?
A: Animal experiment showed that KLT could inhibit proliferation of leukemia cells and induce apoptosis. KLT in small dose could reverse MDR of leukemia cells to improve effect of chemotherapeutic drugs in killing cancer cells. Due to toxic side effect of chemotherapy, many patients cannot tolerate continuous treatment with less effectiveness or they have to extend hospitalization so as to increase economic burden. Clinical data showed that KLT in combination with small dose chemotherapy could improve effectiveness with less toxic side effect as compared with mono-chemotherapy. Therefore those patients with longer time of bone marrow inhibition, not suitable for continuous chemotherapy, can consider KLT combination protocol.
Q62. How is therapeutic effect of KLT in treating malignant lymphoma?
A: Based on statistic data from published clinical studies in China, average effective rate of KLT
combined with chemotherapy in the treatment of malignant lymphoma was 82%, about 26%
higher as compared with average therapeutic effect in control groups as only 56%.
PART III: SAFETY & ADVERSE REACTION
Q63. How is clinical safety of KLT?
A: With its active substance extracted from a natural herb semen coicis, KLT is an emulsive formulation manufactured by advanced production line. Following intravenous emulsion techniques from USA, Sweden and Japan, quality standards such as particle size and distribution, pH value, etc. are strictly controlled and compliant to China pharmacopoeia and SFDA requirements. In Beagle dog test at dose of 7.5ml/kg, 15ml/kg and 30ml/kg respectively for 2 consecutive months, there was no toxic side effect or abnormality in liver/kidney function or blood/urine routines. KLT has had no report on severe adverse reaction since launched in China in 1995. In phase I study in USA, no toxic side effect was observed for patients who applied 500 ml daily for continuous 120 days. And this showed high safety of KLT.
Q64. What are contraindications of KLT?
A: KLT is contraindicated in patients with severe lipid metabolic disturbance (acute shock, acute pancreatitis, pathologic hyperlipidemia and lipid nephorosis) and pregnant women.
Q65. Why pregnant women are contraindicated in KLT?
A: Due to ethical reason pregnant women were not enrolled into KLT clinical studies, which lead to lack of necessary clinical data. So they are contraindicated for safety consideration.
Q66. What are adverse reactions of KLT?
A: Occasional allergy to lipid such as shiver, fever, slight nausea and elevation of SGPT, which will naturally disappear after KLT administration for 3-5 days. Slight phlebitis may be occasionally observed.
Q67. How to clinically manage phlebitis caused by applying KLT?
A: When slight phlebitis is observed, 50-100ml 0.9% sodium chloride or 5% glucose shall be infused before and after KLT. Wet dressing with 20-30% magnesium sulfate solution shall be put on the location.
Q68. Can diabetic cancer patient use KLT?
A: Yes, no problem. Based on reports, KLT could stabilize blood sugar level of advanced senile patients. Short period intravenous administration of KLT has no apparent influence on metabolism of blood sugar and blood lipid of cancer patients.
Q69. Can advanced cancer patient with abnormal liver function use KLT?
A: KLT can be applied in case liver function is slightly abnormal and in severe case KLT shall be cautiously used or contraindicated.
Q70. How to treat hyperlipidemia for patient after applying KLT?
A: KLT can continuously be applied in case of transit or slight hyperlipidemia without special clinical management. In severe case, KLT should be stopped, causes for hyperlipidemia shall be found out and relevant treatment shall be conducted. KLT treatment can be restored after normal blood-lipid level.
Q71. How to manage nausea/vomit after partial resection of liver cancer and KLT application?
A: At first it is defined if nausea or vomit is caused by KLT and symptomatic treatment shall be adopted in slight case while KLT application is continued. In a severe case KLT shall be temporarily stopped until causes are found out.
Q72. How to manage fever after KLT combined with interventional treatment via hepatic artery?
A: The fever may be related to the following factors.
(1) Patient is allergic to lipid with shiver, fever or slight nausea and these symptoms will disappear naturally.
(2) Necrotic tumor substance is absorbed by human body and this will cause fever that is normally below 38°C without other malaise. If patient fever is below 38.5°C, only clinical observation is needed and if it exceeds 38.5°C, physical cooling or symptomatic treatment should be conducted after excluding possibilities of infection and other factors.
Q73. Will severe adverse reaction occur after KLT treatment?
A: Quality standard of KLT strictly follows those from USA, Sweden and Japan. Particle size of KLT has been at world top level. “Particle distribution” is an important QC index. Its quality standard approved by USA is that 95% particles should have diameter below 2 μm and particles with diameter bigger than 5 μm should not be detected. In actual test, average particle diameter in KLT is only 0.189μm with maximum diameter as 0.545μm and 90% particles have average diameters between 0.1-0.4μm. So internal QC level is more strict than standard requirement including osmotic pressure, pH value and stability, etc. Hence, adverse reaction like fat embolism will not occur during application of KLT.
PART IV: PRE-CLINICAL STUDY
Q74. What is pharmacological action of KLT?
A: Based on pharmacodynamic studies, KLT presents remarkable inhibitive effect on various human tumor cell strains transplanted while it enhances body immune system. Moreover, it has notable analgesic effect to resist cancerous pain.
Q75. Which internal organs does KLT distribute after application?
A: In study, mice infused with H marked KLT had extensive internal distribution with peak concentration at sites of lung, liver and spleen.
Q76. What are the half-life period and bioavailability of KLT?
A: 15.84 hours and its bioavailability is 100%.
Q77. What are the major anticancer mechanism of KLT?
A: 1. Cell cycle: inhibit cell multiplication and induce apoptosis by blocking number of cells at G2/M phase to enter G0-G1 phases so as to reduce percentage of cells in S phase.
2. Angiogenesis: notably resist growth of newborn vessels
3. Cell-factor: reduce TNF-α and IL-1 levels and elevate IL-6 level to improve cachexia
4. Gene expression: down-regulate bcl-2 and up-regulate P53
5. Cell enzyme: inhibit expression of MMP-9, COX-2, PKC and FAS
6. NFkB: down-regulate expression of NFkB especially in human breast cancer cell strains
Q78. Which tumor-related gene expressions are affected by KLT?
A: Experiments proved that KLT could up-regulate P53 expression and down-regulate Bcl-2 and MUC1 expressions so as to inhibit tumor invasion and metastasis.
Q79. How can KLT reverse MDR (Multi Drug Resistance) of tumor cells?
A: MDR reversion is a mechanism for effect–enhancement of chemotherapeutic medicine if combined with KLT. Experiment on drug-resisting K562/VCR cell strain showed that RMI (Resistance Modification Index) was 42.6 when concentration of KLT reached 2μl/ml. RMI was 45.2 when KLT concentration was 4μl/ml and RMI reached 54.1 in 8μl/ml KLT concentration. This demonstrated that 2-8μl/ml KLT had apparent reversion on tumor cells’ MDR during application of doxorubicin.
Q80. What is the mechanism behind analgesic effect of KLT?
A: Based on accumulated study, the mechanism is closely related to the following. 1). Coix oil could cause reduction of muscle spasm and shorten its fatigue curve to relieve pain. 2). KLT could inhibit tumor growth and induce apoptosis to shrink tumor size thus reducing invasion and press against tissue and nerve. 3). KLT could down-regulate TNF-α and IL-1 expression to prevent and reverse pain allergy by blocking these factors that play important roles in chronic pain or hyperalgia. 4). In rat-tail stimulation test, coixol, an important component in coix seed, presented similar analgesic effect as aminopyrine in strength.
