Lam CS, Cheng LP, Zhou LM, Cheung YT, Zuo Z. Herb-drug interactions between the medicinal mushrooms Lingzhi and Yunzhi and cytotoxic anticancer drugs: a systematic review. Chin Med 2020; 15:75. [PMID: 32724333 PMCID: PMC7382813 DOI: 10.1186/s13020-020-00356-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Accepted: 07/20/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Lingzhi and Yunzhi are medicinal mushrooms commonly used with cytotoxic chemotherapy in cancer patients in Asian countries. The current systematic review aims to identify potential pharmacokinetic or pharmacodynamic interactions from the existing literature to ensure their effective and safe combination usage in cancer patients. METHODS A systematic search was conducted on nine major Chinese and English databases, including China Journal Net, Allied and Complementary Medicine Database, and Ovid MEDLINE®, etc., to identify clinical, animal, and in-vitro studies that evaluate the effect of combined use of Lingzhi or Yunzhi with cytotoxic drugs. The Jadad scale was used to assess the quality of clinical studies. RESULTS This search identified 213 studies, including 77 clinical studies that reported on the combined use of cytotoxic drugs with Yunzhi (n = 56) or Lingzhi (n = 21). Majority of these clinical studies demonstrated modest methodological quality. In clinical practice, the most commonly used cytotoxic drugs with Lingzhi were cisplatin, 5-fluorouracil (5-FU) and paclitaxel, whereas Tegafur/uracil (UFT)/Tegafur, 5-FU, and mitomycin were the ones used more often with Yunzhi. Only two clinical pharmacokinetic studies were available showing no significant interactions between Polysaccharide K (PSK) and Tegafur. From the pharmacodynamic interactions perspective, combination uses of Yunzhi/Lingzhi with cytotoxic drugs in clinical practice could lead to improvement in survival (n = 31) and quality of life (n = 17), reduction in tumor lesions (n = 22), immune modulation (n = 38), and alleviation of chemotherapy-related side effects (n = 14) with no reported adverse effects. CONCLUSION Our findings suggest that the clinical combination use of Lingzhi or Yunzhi with cytotoxic drugs could enhance the efficacy and ameliorate the adverse effects of cytotoxic drugs, leading to improved quality of life in cancer patients. More high quality clinical studies including pharmacokinetic herb-drug interactions studies are warranted to verify these observations and mechanisms involved. Based on the high quality clinical data, pharmacoepidemiology methods and bioinformatics or data mining could be adopt for further identification of clinical meaningful herb-drug interactions in cancer therapies.

Can polysaccharide K improve therapeutic efficacy and safety in gastrointestinal cancer? a systematic review and network meta-analysis. Oncotarget 2017; 8:89108-89118. [PMID: 29179503 PMCID: PMC5687673 DOI: 10.18632/oncotarget.19059] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2017] [Accepted: 06/19/2017] [Indexed: 02/07/2023] Open
Abstract
Objective To assess the comparative efficacy and safety of polysaccharide K (PSK), with or without chemotherapy, for patients with gastrointestinal cancer (GIC) through a systematic review and network meta-analysis. Materials and Methods We performed a network meta-analysis to identify evidence from randomized controlled trials. We searched PubMed, Embase and the Cochrane Library for publications up to May 2017. The prespecified primary efficacy outcomes were 1–7 year overall survival (OS), while the secondary efficacy outcomes were 1–7 year disease-free survival (DFS); we performed subgroup analyses and meta-regressions according to the cancer type (colorectal, esophagus and gastric cancer) and treatment arms (with or without chemotherapy). Safety outcomes were side effects of PSK. We conducted pairwise meta-analyses using a random-effects model and then performed random-effects network meta-analyses. Results A total of 23 trials were eligible, involving 10684 patients and 13 intervention arms. PSK treatment significantly increased 1–5 year OS and resulted in positive trends in 6–7 year OS; significant increases were also found in 1–7 year DFS, while no increase in side effects was observed. Significant efficacy outcomes obvious in colorectal and gastric cancer groups, as well as PSK combined with chemotherapy groups (iv, po, iv+po). Network meta-analysis revealed that PSK combined with chemotherapy was superior, with significantly increased 3-year and 5-year OS. The study is registered with PROSPERO (CRD42017065193) Conclusions The adjuvant immunochemotherapy agent PSK is effective and safe for patients with GIC. PSK combined with chemotherapy appears to be the preferred application of PSK.

Abstract
Polysaccharide peptide (PSP), isolated from COV-1 strain of Coriolus versicolor, is commonly used as an adjunct in cancer chemotherapy or health supplement in China. Previous studies have shown that PSP decreased antipyrine clearance and inhibited rat CYP2C11-mediated tolbutamide 4-hydroxylation and in human CYP2C9. In this study, the effects of the water extractable fraction of PSP on the metabolism of model CYP1A2, CYP2D6, CYP2E1 and CYP3A4 probe substrates were investigated in pooled human liver microsomes. PSP (1.25-20μM) dose-dependently decreased CYP1A2-mediated metabolism of phenacetin to paracetamol (IC(50) 19.7μM) and CYP3A4-mediated metabolism of testosterone to 6β-hydroxytestosterone (IC(20) 7.06μM). Enzyme kinetics studies showed the inhibition of CYP1A2 activity was competitive and concentration-dependent (K(i)=18.4μM). Inhibition of testosterone to 6β-hydroxytestosterone was also competitive and concentration-dependent (K(i)=31.8μM). Metabolism of dextromethorphan to dextrorphan (CYP2D6-mediated) and chlorzoxazone to 6-hydroxychlorzoxazone (CYP2E1-mediated) was only minimally inhibited by PSP, with IC(20) values at 15.6μM and 11.9μM, respectively. This study demonstrated that PSP competitively inhibited the CYP1A2- and CYP3A4-mediated metabolism of model probe substrates in human liver microsomes in vitro. The relatively high K(i) values for CYP1A2 and CYP3A4 would suggest a low potential for PSP to cause herb-drug interaction related to these CYP isoforms.

Abstract
Polysaccharide peptide (PSP), isolated from COV-1 strain of Coriolus versicolor, is commonly used as an adjunct in cancer chemotherapy in China. Previous studies have shown that PSP decreased antipyrine clearance and inhibited CYP2C11-mediated tolbutamide 4-hydroxylation in the rat both in vitro and in vivo. In this study, the effects of water extractable fraction of PSP on tolbutamide 4-hydroxylation was investigated in pooled human liver microsomes and in specific human CYP2C9 isoform. PSP (2.5-20μM) dose-dependently decreased the biotransformation of tolbutamide to 4-hydroxy-tolbutamide. Enzyme kinetics studies showed inhibition of tolbutamide 4-hydroxylase activity was competitive and concentration-dependent. In pooled human liver microsomes, PSP had a K(i) value of 14.2μM compared to sulfaphenazole, a human CYP2C9 inhibitor, showed a K(i) value of 0.32μM. In human CYP2C9 isoform, the K(i) value of PSP was 29.5μM and the K(i) value of sulfaphenazole was 0.04μM. This study demonstrated that PSP can competitively inhibit tolbutamide 4-hydroxylation in both pooled human liver microsomes and specific human CYP2C9 in vitro. This study compliments previous findings in the rat that PSP can inhibit human tolbutamide 4-hydroxylase, but the relatively high K(i) values in human CYP2C9 would suggest a low potential for PSP to cause herb-drug interaction.

Abstract
OPINION STATEMENT Non-prescription herbal remedies are commonly used by cancer patients in efforts to control their disease or to manage symptoms associated with cancer and cancer treatments. We address the issues surrounding the use of herbs, herbal compounds, and other botanical agents in the oncology context. Botanicals are biologically active agents that can be useful under appropriate circumstances, but they may be counterproductive when used by patients on chemotherapy or on other prescription medications. Herbs and other botanical agents, despite common public belief, are not benign. They should be understood as unrefined pharmaceuticals, with the capacity to produce physiologic change for better or worse. Indeed, many prescription drugs, chemotherapeutic agents among them, were derived from plants and other natural agents, and the search for additional constituents of plants, animals, and minerals for use as pharmaceutical agents remains an active effort on many fronts. Cautions, appropriate application, and potential utility of botanical agents are discussed below, and sources of reliable information are provided.

Abstract
The effects of polysaccharide peptide (PSP), an immunomodulator isolated from Coriolus versicolor COV-1, on glutathione (GSH) and GSH-related enzymes was investigated in C57 mouse. Administration of PSP (1-4 micromole/kg, i.p.) produced a transient, dose-dependent depletion (10-37%) of hepatic GSH, with no effect on serum glutamic-pyruvic transaminase (SGPT) activity. Blood GSH was depleted (6-25%) at 3 h, followed by a rebound increase above the control GSH level (20%) at 18 h. The GSSG/GSH ratio, a measure of oxidative stress, was increased 3 h after PSP treatment but returned to normal levels at 24 h. Sub-chronic treatment of PSP (1-4 micromole/kg/day, i.p.) for seven days did not produce any significant changes in hepatic GSH levels and the GSSG/GSH ratio when measured 24 h after the final dose of PSP. PSP had little effect on glutathione transferase (GST), glutathione reductase (GSSG reductase) and glutathione peroxidase (GPX) activities in the liver. However, a dose-dependent increase in blood GPX activity (30-48%) was observed at 3h, which coincided with the increase in the GSSG/GSH ratio. The increase in blood GPX activity may be a responsive measure to deal with the transient oxidative stress induced by PSP treatment. The results showed that PSP only caused a transient perturbation on hepatic glutathione without affecting the GSH-related enzymes such as GST, GSSG reductase and GPX. The observed changes in blood GSH simply reflected the intra-organ translocation of glutathione, as the glutathione-related enzymes were not significantly affected by PSP treatment.

Abstract
Polysaccharide peptide (PSP), isolated from COV-1 strain of Coriolus versicolor, is commonly used as an adjunct in cancer chemotherapy in China. In this study, the effects of whole PSP extract and water extract of PSP on 4-hydroxylation of tolbutamide were investigated in rat liver microsomes in vitro and in vivo in the rat. Both the whole PSP extract and the water soluble fraction (0.5-20 microM) decreased the metabolism of tolbutamide to 4-hydroxytolbutamide in vitro. Enzyme kinetics studies showed that PSP inhibited tolbutamide 4-hydroxylase activity in a competitive, concentration-dependent manner. The whole PSP extract had a Ki value of 12.6 microM and IC50 at 18.4 microM, while the water extract had a Ki value of 6.9 microM and IC50 at 9.8 microM. Sulphaphenazole, a specific human CYP2C9 inhibitor, showed a Ki value of 30.8 microM and IC50 at 44.0 microM in the test system. In the pharmacokinetic studies in vivo, acute PSP (4 micromol/kg, i.p.) treatment did not produce significant changes in tolbutamide clearance, but produced a decrease in the Cinitial (7.4%) and an increase in the Vd (7.4%). Sub-chronic pre-treatment of PSP (1-2 micromol/kg/day, i.p.) for three days did not affect the clearance and AUC of tolbutamide, but the Cinitial was decreased, together with increases in the T1/2, and Vd. The formation of 4-hydroxytolbutamide in vivo was decreased in both acute and sub-chronic studies. Taken together, this study demonstrated the PSP can inhibit tolbutamide 4-hydroxylation both in vitro and in vivo. Despite the fact that CYP isoforms that metabolise tolbutamide are different between rat and human liver due to different catalytic characteristics, and rat studies may not be directly extrapolatable to man, the concomitant use of PSP with other CYP2C substrates should be carefully monitored.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is a leading cause of cancer deaths, and over 60% of patients present with advanced stages. Although polysaccharide peptides (PSP), isolated from the fungus Coriolus versicolor, have been reported to have anti-tumor effects, its clinical efficacy has not been properly evaluated. METHODS Double-blind placebo-controlled randomized study to evaluate the effects of 28-day administration of PSP (Windsor Pharmaceutical, Hong Kong) on patients, who had completed conventional treatment for advanced NSCLC. RESULTS Thirty-four patients, with no significant difference in their baseline demographic, clinical or tumor characteristics, or previous treatment regimes (P>0.05) were recruited into each of the PSP and control arms. After 28-day treatment, there was a significant improvement in blood leukocyte and neutrophil counts, serum IgG and IgM, and percent of body fat among the PSP, but not the control, patients (P<0.05). Although the evaluable PSP patients did not improve in NSCLC-related symptoms, there were significantly less PSP patients withdrawn due to disease progression, than their control counterparts (5.9 and 23.5%, respectively; P=0.04; OR 4.00). There was no reported adverse reaction attributable to the trial medications. CONCLUSION PSP treatment appears to be associated with slower deterioration in patients with advanced NSCLC.

Abstract
We studied the effect of protein-bound polysaccharide PSK on the activation of the human natural killer cell line NKL. We observed an increased natural killer cytotoxic activity against different tumor cells (K562, Daudi, and U937) when a standard 2- to 3-h 51chromium release assay was performed. The results parallel those obtained after treatment of the NKL cell line with interleukin-2. The highest cytotoxic activity was reached at a concentration of 100 microg/ml of PSK. This natural killer activation was inhibited when the PSK dose was 1,000 microg/ml. None of the cell surface markers that were analyzed by fluorescence-activated cell sorting showed variations after PSK or interleukin-2 treatment of NKL cells. These markers included CD2, CD11b, CD11c, CD18, CD16, CD54, CD56, CD98, CD25, CD122, HLA class I, HLA class II, CD94, ILT2, p58.1, p70, and NKp46. One of these markers (NKp46) is a major triggering receptor reported to be involved in the natural cytotoxicity of fresh or cultured human natural killer cells. In our study, another triggering receptor must be implicated in PSK-induced natural killer lysis. Our data suggest that PSK is an important biological response modifier of natural killer cells in vitro and may prove to be useful for the study of human natural killer cell biology.

Abstract
BACKGROUND The results of surgical treatment for oesophageal squamous cell cancer have improved over recent decades, but the long-term prognosis for patients with tumours of stage II or higher is still unsatisfactory. While uncontrolled series of adjuvant or neoadjuvant treatment have reported favourable survival rates, the true benefit of multimodal treatment can be determined only by randomized controlled trials. METHODS The literature was searched for prospective randomized controlled trials (PRCTs) examining the effect of neoadjuvant or adjuvant treatment on the long-term survival of patients with squamous cell cancer of the oesophagus. RESULTS More than 30 PRCTs studying multimodal treatment concepts aimed at improving the prognosis of squamous cell carcinoma of the oesophagus were identified. These trials have not documented improved survival by adjuvant radiotherapy or chemotherapy. Following neoadjuvant radiotherapy or chemotherapy (or a combination of both), resectability of squamous cell carcinoma is not increased, the postoperative mortality rate appears to be higher and survival is not prolonged. CONCLUSION Past multimodality protocols have not improved the prognosis of squamous carcinoma of the oesophagus. Careful design and reporting, together with strict control of surgical procedures, should allow more meaningful analysis of future multimodal treatment studies. At present, neoadjuvant or adjuvant treatment cannot be recommended outside such clinical protocols.
