In stage IV pulmonary adenocarcinoma patients, treatment with Traditional Chinese Medicine alone gives prognostically superior results to treatment with Platinum-Based Chemotherapy alone. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 121:155087. [PMID: 37832267 DOI: 10.1016/j.phymed.2023.155087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 09/06/2023] [Accepted: 09/11/2023] [Indexed: 10/15/2023]
Abstract
BACKGROUND About 30% of pulmonary stage IV adenocarcinomas die within 3 months of diagnosis. Western medical treatments with Platinum-Based Chemotherapy=PBC and tyrosine-kinase inhibitors Targeted Therapy=TT can improve prognosis. In China, Traditional Chinese Medicine herbal treatments (TCM) are often used in addition to PBC and TT. A considerable number of patients refuse Western medical treatments and use TCM alone. However, the survival impact of the latter is unknown. HYPOTHESES TESTED Treatment with TCM alone is prognostically superior to PBC alone. Addition of PBC or TT or both TT to TCM improves survival. METHODS In this prospective observational, non-interventional study of 1017 consecutive first-onset stage IV NSCLC patients with up to 10 years follow-up, 261 who Died of Disease (DOD) within 3 months were omitted, as they never got the optimal Western medical therapies. All 218 non-adenocarcinomas were also omitted, leaving 538 stage IV adenocarcinomas treated by TCM alone (n = 29), PBC alone (N = 19) and TCM and other Western medical combinations (299 TCM and PBC, 50 TCM and TT, 141 TCM and PBC and TT) with 3 - 120 months follow-up. Survivals were compared using Alive with Disease (AWD) and DOD as endpoints. RESULTS The patients treated only with TCM had 7 months better median survival than those that received PBC alone (17 and 10 months). The patients that received TCM and PBC had a better median survival (24 months) than TCM alone and much better than PBC alone. None of the patients that received TCM alone survived > 54 months, whereas 18% of TCM and PBC patients survived much longer. Over the observation period of 3 - 120 months, survivals of TCM and TT, TCM and PBC and TT, and TCM and PBC were not different and therefore grouped as TCM and Western medicines. Median survival times of PBC alone and TCM alone were lower than that of TCM and Western medical treatments (p < 0.0001, 10, 17 and 27 months). CONCLUSIONS Pulmonary stage IV adenocarcinoma patients with at least 3 months survival, treated with TCM alone have a significantly better survival than those treated with PBC alone. Adding Western PBC, TT or both to TCM further improves prognosis.

Int J Mol Sci 2023; 24:9819. [PMID: 37372967 DOI: 10.3390/ijms24129819] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 06/01/2023] [Accepted: 06/02/2023] [Indexed: 06/29/2023] Open
Abstract
Caffeic acid phenethyl ester (CAPE) contains antibiotic and anticancer activities. Therefore, we aimed to investigate the anticancer properties and mechanisms of CAPE and caffeamide derivatives in the oral squamous cell carcinoma cell (OSCC) lines SAS and OECM-1. The anti-OSCC effects of CAPE and the caffeamide derivatives (26G, 36C, 36H, 36K, and 36M) were evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test. Cell cycle and total reactive oxygen species (ROS) production were analyzed using flow cytometry. The relative protein expression of malignant phenotypes was determined via Western blot analysis. The results showed that 26G and 36M were more cytotoxic than the other compounds in SAS cells. After 26G or 36M treatment for 48 h, cell cycle S phase or G2/M phase arrest was induced, and cellular ROS increased at 24 h, and then decreased at 48 h in both cell lines. The expression levels of cell cycle regulatory and anti-ROS proteins were downregulated. In addition, 26G or 36M treatment inhibited malignant phenotypes through mTOR-ULK1-P62-LC3 autophagic signaling activated by ROS generation. These results showed that 26G and 36M induce cancer cell death by activating autophagy signaling, which is correlated with altered cellular oxidative stress.

Cells 2022; 11:cells11040641. [PMID: 35203294 PMCID: PMC8870566 DOI: 10.3390/cells11040641] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 02/10/2022] [Accepted: 02/11/2022] [Indexed: 02/04/2023] Open
Abstract
Cryptocaryone (CPC) is a bioactive dihydrochalcone derived from Cryptocarya plants, and its antiproliferation was rarely reported, especially for ovarian cancer (OVCA). This study aimed to examine the regulation ability and mechanism of CPC on three histotypes of OVCA cells (SKOV3, TOV-21G, and TOV-112D). In a 24 h MTS assay, CPC showed antiproliferation effects to OVCA cells, i.e., IC50 values 1.5, 3, and 9.5 μM for TOV-21G, SKOV3, and TOV-112D cells. TOV-21G and SKOV3 cells showed hypersensitivity to CPC when applied for exposure time and concentration experiments. For biological processes, CPC stimulated the generation of reactive oxygen species and mitochondrial superoxide and promoted mitochondrial membrane potential dysfunction in TOV-21G and SKOV3 cells. Apoptosis was detected in OVCA cells through subG1 accumulation and annexin V staining. Apoptosis signaling such as caspase 3/7 activities, cleaved poly (ADP-ribose) polymerase, and caspase 3 expressions were upregulated by CPC. Specifically, the intrinsic and extrinsic apoptotic caspase 9 and caspase 8 were overexpressed in OVCA cells following CPC treatment. Moreover, CPC also stimulated DNA damages in terms of γH2AX expression and increased γH2AX foci. CPC also induced 8-hydroxy-2’-deoxyguanosine DNA damages. These CPC-associated principal biological processes were validated to be oxidative stress-dependent by N-acetylcysteine. In conclusion, CPC is a potential anti-OVCA natural product showing oxidative stress-dependent antiproliferation, apoptosis, and DNA damaging functions.

Oral Surg Oral Med Oral Pathol Oral Radiol 2020; 130:419-427. [PMID: 32868254 DOI: 10.1016/j.oooo.2020.06.020] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Revised: 05/12/2020] [Accepted: 06/26/2020] [Indexed: 01/07/2023]
Abstract
OBJECTIVES The aim of this study was to investigate whether nobiletin (NOB) can inhibit the proliferation of oral squamous cell carcinoma (OSCC) cells by promoting apoptosis, oxidative stress (reactive oxygen species [ROS]), and DNA damage. STUDY DESIGN OSCCs were treated with different concentrations of NOB (25, 50, and 100 µM) for different amounts of time (0, 24, 48, and 72 hours). The viability of NOB was assessed by using MTT-based cell viability assays. Flow cytometry was used to assess cell apoptosis, and the expressions of capase-3 and poly (adenosine diphosphate-ribose) polymerase (PARP) were assessed by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analyses. The intensity of ROS fluorescence was measured by using a spectrophotometer. The expression of γH2AX and 8-Oxo-20-deoxyguanosine (8-oxodG) were assessed to determine the degree of DNA damage. RESULTS We observed that NOB decreased OSCC cell viability in a dose- and time-dependent manner but had little effect on primary normal human oral epithelial cells (H0 ECs). Moreover, with the increase in NOB concentration and treatment time, capase-3, PARP messenger RNA (mRNA), and protein levels gradually increased, as did annexin V- and 7 adducin (ADD)-mediated apoptosis. In addition, NOB also increased the levels of ROS and DNA damage in a concentration- and time-dependent manner. CONCLUSIONS NOB can inhibit OSCC cell by promoting apoptosis, ROS production, and DNA damage.

Abstract
As complementary and alternative medicine (CAM) becomes more popular, it is being used in cancer patients to aid in recovery or to treat symptoms associated with the current chemotherapy. Numerous papers exist that discuss patients using CAM with cancer chemotherapy and their outcomes-both positive and negative. However, in the case of the negative outcomes, the reason for the dangers or interactions with drugs are not made clear. Indeed, many chemotherapy regimens are rendered less effective by the well-meaning but uninformed patient or their family members and friends. Similarly, reports of positive outcomes with CAM and chemotherapy provide a strong basis for further research, but do not identify specific mechanisms of action. These small clinical studies and in vitro studies identify a necessary area for further research and provide a much needed, although often rejected, alternative look at whole treatment plans. Careful review of the available information and evaluation of the nature of the CAM effects are necessary to combat the misunderstanding and sometimes unwarranted claims over CAM use. This mini review will explore some of the commonly used CAM agents and their mechanisms of interactions with other treatments. Suggestions as to which agents can be safe and when to use them will be an integral part of this review.

Abstract
Nepenthes plants are regarded as a kind of Traditional Chinese Medicine for several diseases but its anticancer activity remain unclear. The subject of this study is to evaluate the antiproliferation effects on oral cancer cells by Nepenthes plants using ethyl acetate extract of Nepenthes adrianii x clipeata (EANA). Cell viability was detected using MTS assay. Its detailed mechanisms including cell cycle, apoptosis, oxidative stress, and DNA damage were explored by flow cytometry or western blotting. For 24 hours EANA treatment, five kinds of oral cancer cells (CAL 27, Ca9-22, OECM-1, HSC-3, and SCC9) show IC50 values of cell viability ranging from 8 to 17 μg/mL but the viability of normal oral cells (HGF-1) remains over 80%. Subsequently, CAL 27 and Ca9-22 cells with high sensitivity to EANA were chosen to investigate the detailed mechanism. EANA displays the time course and concentration effects for inducing apoptosis based on flow cytometry (subG1 and annexin V analyses) and western blotting [cleaved poly (ADP-ribose) polymerase (c-PARP)]. Oxidative stress and DNA damage were induced by EANA treatments in oral cancer cells through reactive oxygen species (ROS), mitochondrial membrane potential disruption, mitochondrial superoxide, and γH2AX. All these changes of EANA treatments in oral cancer cells were reverted by the ROS scavenger N-acetylcysteine pretreatment. Therefore, EANA induces preferential killing, apoptosis, and DNA damage against oral cancer cells through oxidative stress.

Abstract
Objectives: This scoping review evaluates two decades of methodological advances made by “whole systems research” (WSR) pioneers in the fields of traditional, complementary, and integrative medicine (TCIM). Rooted in critiques of the classical randomized controlled trial (RCT)'s suitability for evaluating holistic, complex TCIM interventions, WSR centralizes the principle of “model validity,” representing a “fit” between research design and therapeutic paradigm. Design: In consultation with field experts, 41 clinical research exemplars were selected for review from across 13 TCIM disciplines, with the aim of mapping the range and methodological characteristics of WSR studies. Using an analytic charting approach, these studies' primary and secondary features are characterized with reference to three focal areas: research method, intervention design, and outcome assessment. Results: The reviewed WSR exemplars investigate a wide range of multimodal and multicomponent TCIM interventions, typified by wellness-geared, multitarget, and multimorbid therapeutic aims. Most studies include a behavioral focus, at times in multidisciplinary or team-based contexts. Treatments are variously individualized, often with reference to “dual” (biomedical and paradigm-specific) diagnoses. Prospective and retrospective study designs substantially reflect established biomedical research methods. Pragmatic, randomized, open label comparative effectiveness designs with “usual care” comparators are most widely used, at times with factorial treatment arms. Only two studies adopt a double-blind, placebo-controlled RCT format. Some cohort-based controlled trials engage nonrandomized allocation strategies (e.g., matched controls, preference-based assignment, and minimization); other key designs include single-cohort pre–post studies, modified n-of-1 series, case series, case report, and ethnography. Mixed methods designs (i.e., qualitative research and economic evaluations) are evident in about one-third of exemplars. Primary and secondary outcomes are predominantly assessed, at multiple intervals, through patient-reported measures for symptom severity, quality of life/wellness, and/or treatment satisfaction; some studies concurrently evaluate objective outcomes. Conclusions: Aligned with trends emphasizing “fit-for-purpose” research designs to study the “real-world” effectiveness of complex, personalized clinical interventions, WSR has emerged as a maturing scholarly discipline. The field is distinguished by its patient-centered salutogenic focus and engagement with nonbiomedical diagnostic and treatment frameworks. The rigorous pursuit of model validity may be further advanced by emphasizing complex analytic models, paradigm-specific outcome assessment, inter-rater reliability, and ethnographically informed designs. Policy makers and funders seeking to support best practices in TCIM research may refer to this review as a key resource.

Abstract
Studies have reported that taxol (TAX) is an effective drug for the treatment of colorectal cancer; however, its application inevitably results in drug resistance. Overexpression of Yes-associated protein (YAP) is considered one of the factors that cause TAX resistance, which may be inhibited by verteporfin (VP) treatment. The present study aimed to confirm the role of YAP in TAX resistance and to investigate whether the drug sensitivity of the TAX-resistant LOVO/TAX cell line to TAX is affected by VP treatment. The role of YAP in TAX resistance was first determined through vector-mediated overexpression and inhibition of YAP in cells. Reverse-transcription quantitative polymerase chain reaction and western blot analysis were performed for detection of associated mRNA and protein, respectively. An MTT assay was used to detect the drug sensitivity of cells to TAX. The results suggested that compared with that in the native LOVO cell line, YAP expression was significantly increased in LOVO/TAX cells. YAP gene silencing markedly enhanced the drug sensitivity of LOVO/TAX cells to TAX and, on the contrary, the drug sensitivity notably declined when YAP was overexpressed in LOVO cells. The results indicated that YAP gene expression and TAX resistance were correlated. VP treatment suppressed YAP expression and increased the drug sensitivity of LOVO/TAX cells to TAX in a dose-dependent manner. In addition, compared with VP alone, VP and TAX combination therapy had a greater inhibitory effect on YAP expression. VP treatment enhanced the drug sensitivity of LOVO/TAX cells to TAX through inhibiting YAP expression.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Patients with lung cancer are frequently treated with Western medical treatments. Recently, patients have begun to use Chinese medicine to strengthen the immune system and alleviate side effects. AIM OF THE STUDY We aimed to evaluate the association between mortality rate and early use of Chinese herbal products (CHPs) among patients with lung cancer. MATERIALS AND METHODS We conducted a retrospective cohort study based on the National Health Insurance Research Database, Taiwan Cancer Registry, and Cause of Death Data. Patients with newly diagnosed lung cancer between 2002 and 2010 were classified as either the CHP (n = 422) or the non-CHP group (n = 2828) based on whether they used CHP within 3 months after first diagnosis of lung cancer. A robust Cox regression model was used to examine the hazard ratio (HR) of death for propensity score (PS) matching samples. RESULTS After PS matching, average survival time of the CHP group was significantly longer than that of the non-CHP group. The adjusted HR (0.82; 95% CI: 0.73-0.92) in the CHP group was lower than the non-CHP group. Stratified by clinical cancer stages, CHP group had longer survival time in stage 3 subgroup. When the exposure period of CHP use was changed from 3 to 6 months, results remained similar (HR = 0.85; 95% CI: 0.76-0.95). CONCLUSION Results indicated that patients with lung cancer who used CHP within 3 months after first diagnosis had a lower hazard of death than non-CHP users, especially for stage 3 lung cancer. Further experimental studies are needed to examine the causal relationship.

Guo H, Liu JX, Li H, Baak JPA. In Metastatic Non-small cell Lung Cancer Platinum-Based Treated Patients, Herbal Treatment Improves the Quality of Life. A Prospective Randomized Controlled Clinical Trial. Front Pharmacol 2017; 8:454. [PMID: 28769793 PMCID: PMC5511837 DOI: 10.3389/fphar.2017.00454] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2017] [Accepted: 06/23/2017] [Indexed: 12/22/2022] Open
Abstract
Background: According to clinical experience, Traditional Chinese Medicine (TCM) herbs added to platinum-based therapy (PBT) improve the Quality of Life (QOL) in metastatic non-small cell lung cancer (NSCLC) patients, but this must be prospectively validated. Patients and Methods: Based on clinical impressions regarding the effect of adding TCM herbs to platinum-based chemotherapy, we anticipated that 2 × 21 patients would be sufficient to obtain significant results with an α < 0.05 and power (1 - β) of 90%. To be on the safe side, we enrolled at least 28 patients in each group. In a prospective randomized controlled trial, 61 uniquely defined consecutive patients (PBT+PLACEBO, N = 32; PBT+TCM, N = 29) with stage IIIB-IV, Eastern Cooperative Oncology Group (ECOG) performance scores (PS) = 0–1 and TCM syndrome combined Qi-Yin deficiency were enrolled. These 61 patients were selected from originally 154 consecutive stage IIIB-IV lung cancer patients in the enrollment period. Patients were hospitalized and strictly controlled/surveyed during the entire 2-month treatment period, to guarantee use of or abstinence from TCM herbal and placebo fluids. Occurrence of nausea-vomiting, QOL by Functional Assessment of Cancer Therapy-Lung (FACT-L) scales and changes in ECOG “improved and stable rates” were compared before and after two treatment cycles. Results: Before treatment, the clinico-pathologic and QOL features in PBT+PLACEBO and PBT+TCM patients did not differ (P > 0.10). The only side effects attributed by some of the patients to the TCM herbs were transient, mild gastric/abdominal heaviness in the first 2 weeks, but these also occurred amongst the PBT+PLACEBO patients (17 and 13%, P > 0.10). The incidence rates of nausea during treatment were 17% in PBT+TCM versus 75% in PBT+PLACEBO; vomiting rates were 14 and 56% (P < 0.0001 and 0.002). Moreover, ECOG “improved and stable rates” were 90% in the PBT+TCM versus 69% in the PBT+PLACEBO group (P = 0.04). In PBT+TCM patients, FACT-L social/familial and functional subscales were better after 2 months’ treatment (P = 0.02 and 0.03). Contrarily, in PBT+PLACEBO patients, the QOL variables total score, physical and emotional subscales were worse after PBT treatment (P = 0.03, 0.0001, and 0.003). Conclusion: In stage IIIB-IV ECOG-PS = 0–1 NSCLC patients with Qi-Yin deficiency and platinum-based chemotherapy, adding TCM herbal medication improves the QOL. As this category of patients constitutes 40% of all metastatic NSCLCs, these results could have significant clinical impact.

Ethyl acetate extract from Selaginella doederleinii Hieron inhibits the growth of human lung cancer cells A549 via caspase-dependent apoptosis pathway. JOURNAL OF ETHNOPHARMACOLOGY 2016; 190:261-71. [PMID: 27292193 DOI: 10.1016/j.jep.2016.06.029] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2016] [Revised: 06/08/2016] [Accepted: 06/08/2016] [Indexed: 05/22/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Selaginella doederleinii Hieron has been used as a folk medicine for the treatment of different cancers, especially for nasopharyngeal carcinoma, lung cancer and trophoblastic tumor in China. Previously, the ethyl acetate extract from S. doederleinii (SDEA extract) showed favorable anti-cancer potentials. However, the main chemical composition and anticancer mechanism of the SDEA extract were still not very clear. Until now, there are no reports available about the oral toxicity of the extract. AIM OF STUDY The present study was to further elucidate the chemical composition and anti-lung cancer mechanism of the SDEA extract, and evaluate the acute oral toxicity of the extract. MATERIALS AND METHODS The SDEA extract was separated and analysed by HPLC to disclose its main chemicals. The effects of the extract were then investigated in vitro on cell viability, apoptosis and cell cycle using fluorescence microscopy and flow cytometry, and the molecular mechanism against human lung cancer cells A549 was further studied by western blot assays. The in vivo anti-cancer effect of the extract was evaluated in A549 xenograft mice model by histochemical assay, and tumor growth, microvascular density (MVD) and Ki67 expression were also measured. In addition, acute oral toxicity test of the extract was executed in mice. RESULTS SDEA extract mainly contained eight biflavonoids. The extract caused the loss of mitochondrial membrane potential and induced cell apoptosis by upregulating Bax, downregulating Bcl-2, activating caspase-9 and caspase-3 and blocked the cell cycle in S phase. The extract reduced expression of antigen Ki67, decreased MVD, and significantly inhibited the tumor growth. The extract did not show apparent oral acute toxicity in healthy mice. CONCLUSION The SDEA extract exerted anti-tumor effect through activating mitochondrial pathways and reducing Ki67 expression and MVD. Low oral acute toxicity suggested it a promising chemotherapy agent.

Abstract
Background Treatment selection for elderly patients with lung cancer must balance the benefits of curative/life-prolonging therapy and the risks of increased mortality due to comorbidities. Lung cancer trials generally exclude patients with comorbidities and current treatment guidelines do not specifically consider comorbidities, so treatment decisions are usually made on subjective individual-case basis. Methods Impacts of surgery, radiation, and chemotherapy mono-treatment as well as combined chemo/radiation on one-year overall survival (compared to no-treatment) are studied for stage-specific lung cancer in 65+ y.o. patients. Methods of causal inference such as propensity score with inverse probability weighting (IPW) for time-independent and marginal structural model (MSM) for time-dependent treatments are applied to SEER-Medicare data considering the presence of comorbid diseases. Results 122,822 patients with stage I (26.8%), II (4.5%), IIIa (11.5%), IIIb (19.9%), and IV (37.4%) lung cancer were selected. Younger age, smaller tumor size, and fewer baseline comorbidities predict better survival. Impacts of radio- and chemotherapy increased and impact of surgery decreased with more advanced cancer stages. The effects of all therapies became weaker after adjustment for selection bias, however, the changes in the effects were minor likely due to the weak selection bias or incompleteness of the list of predictors that impacted treatment choice. MSM provides more realistic estimates of treatment effects than the IPW approach for time-independent treatment. Conclusions Causal inference methods provide substantive results on treatment choice and survival of older lung cancer patients with realistic expectations of potential benefits of specific treatments. Applications of these models to specific subsets of patients can aid in the development of practical guidelines that help optimize lung cancer treatment based on individual patient characteristics.

Abstract
Longitudinal observational data are required to assess the association between exposure to β-interferon medications and disease progression among relapsing-remitting multiple sclerosis (MS) patients in the "real-world" clinical practice setting. Marginal structural Cox models (MSCMs) can provide distinct advantages over traditional approaches by allowing adjustment for time-varying confounders such as MS relapses, as well as baseline characteristics, through the use of inverse probability weighting. We assessed the suitability of MSCMs to analyze data from a large cohort of 1,697 relapsing-remitting MS patients in British Columbia, Canada (1995-2008). In the context of this observational study, which spanned more than a decade and involved patients with a chronic yet fluctuating disease, the recently proposed "normalized stabilized" weights were found to be the most appropriate choice of weights. Using this model, no association between β-interferon exposure and the hazard of disability progression was found (hazard ratio = 1.36, 95% confidence interval: 0.95, 1.94). For sensitivity analyses, truncated normalized unstabilized weights were used in additional MSCMs and to construct inverse probability weight-adjusted survival curves; the findings did not change. Additionally, qualitatively similar conclusions from approximation approaches to the weighted Cox model (i.e., MSCM) extend confidence in the findings.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese Medicine (TCM) has become more popular among cancer patients in the Western world, who often use Chinese herbs as adjuvant therapy to reduce the adverse effects of conventional chemotherapy. However, pharmacokinetic (PK) interactions between Chinese herbs and anticancer drugs can occur and have dramatic consequences for these patients. Currently, only a few possible PK interactions between Chinese herbs and conventional Western drugs have been documented. AIM OF THE STUDY Since the drug-metabolizing enzyme cytochrome P450 3A4 (CYP3A4) contributes to most of the PK interactions with (anticancer) drugs, the effect of four Chinese herbs (Oldenlandia diffusa, Codonopsis tangshen, Rehmannia glutinosa and Astragalus propinquus) on the activity and expression of CYP3A4 was investigated in vitro. MATERIALS AND METHODS Ethanol and water-ethanol extracts of the four Chinese herbs were prepared from raw material. CYP3A4 inhibition was assessed by the use of Supersomes™ in a fluorescence assay. Furthermore, CYP3A4 induction was evaluated in a human pregnane X receptor (hPXR)-mediated CYP3A4 reporter gene assay and a quantitative real time PCR assay, both in human colon adenocarcinoma-derived LS180 cells (LS180). RESULTS Extracts of Oldenlandia diffusa, Codonopsis tangshen, Rehmannia glutinosa and Astragalus propinquus inhibited CYP3A4 in human CYP3A4 Supersomes™ (IC50 values: 17-83 µg/mL). Oldenlandia diffusa and Rehmannia glutinosa significantly induced PXR-mediated CYP3A4 (p<0.001). Oldenlandia diffusa also significantly induced CYP3A4 mRNA levels (p<0.001 at 250 µg/mL). CONCLUSIONS Concomitant use of Oldenlandia diffusa and Rehmannia glutinosa could result in induction of CYP3A4, leading to a reduced efficacy of drugs that are CYP3A4 substrates and have a narrow therapeutic window. Because of the possible enhanced toxicity caused by CYP3A4 inhibition, clinical effects of CYP3A4 inhibition by Astragalus propinquus and Codonopsis tangshen must also be taken into account. In conclusion, herb-drug interactions between Chinese herbs and various CYP3A4 substrates can occur. Further research to investigate the clinical relevance of the interactions caused by Oldenlandia diffusa, Codonopsis tangshen, Rehmannia glutinosa and Astragalus propinquus is required.

Abstract
BACKGROUND Many women diagnosed with breast cancer receive both standard cancer treatment and care from providers trained in the emerging field of medicine called integrative oncology (IO) in which science-based complementary and alternative medical therapies are prescribed by physicians. The effectiveness of IO services has not been fully studied, so is yet unknown. PURPOSE Determine if a matched, case-controlled prospective outcomes study evaluating the efficacy and safety of breast cancer IO care is feasible. METHODS Methodological proof of principle requires demonstration that (1) it is possible to find matched control breast cancer patients using the Surveillance, Epidemiology and End RESULTS Results. A pilot study was conducted in 2008 (n = 14) to determine if matched controlled women could be identified in the western Washington SEER database. All 14 women who were approached agreed to participate. The cases were matched to the CSS along 5 variables: age and stage at diagnosis, race, and marital and Estrogen Receptors/Progesterone Receptors (ER/PR) status. Multiple matches were found for 12 of the 14 participants. CONCLUSION A prospective cohort study with a matched comparison group is a feasible and potentially rigorous STUDY DESIGN It may provide valuable data for the evaluation of the effectiveness of IO care on patient health, relapse rate, and health-related quality of life (HRQOL). A federally funded matched case controlled outcomes study is currently under way at Bastyr University and the Fred Hutchinson Cancer Research Center.
