Dong D, Yu X, Xu J, Yu N, Liu Z, Sun Y. Cellular and molecular mechanisms of gastrointestinal cancer liver metastases and drug resistance. Drug Resist Updat 2024; 77:101125. [PMID: 39173439 DOI: 10.1016/j.drup.2024.101125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2024] [Revised: 07/30/2024] [Accepted: 08/05/2024] [Indexed: 08/24/2024]
Abstract
Distant metastases and drug resistance account for poor survival of patients with gastrointestinal (GI) malignancies such as gastric cancer, pancreatic cancer, and colorectal cancer. GI cancers most commonly metastasize to the liver, which provides a unique immunosuppressive tumour microenvironment to support the development of a premetastatic niche for tumor cell colonization and metastatic outgrowth. Metastatic tumors often exhibit greater resistance to drugs than primary tumors, posing extra challenges in treatment. The liver metastases and drug resistance of GI cancers are regulated by complex, intertwined, and tumor-dependent cellular and molecular mechanisms that influence tumor cell behavior (e.g. epithelial-to-mesenchymal transition, or EMT), tumor microenvironment (TME) (e.g. the extracellular matrix, cancer-associated fibroblasts, and tumor-infiltrating immune cells), tumor cell-TME interactions (e.g. through cytokines and exosomes), liver microenvironment (e.g. hepatic stellate cells and macrophages), and the route and mechanism of tumor cell dissemination (e.g. circulating tumor cells). This review provides an overview of recent advances in the research on cellular and molecular mechanisms that regulate liver metastases and drug resistance of GI cancers. We also discuss recent advances in the development of mechanism-based therapy for these GI cancers. Targeting these cellular and molecular mechanisms, either alone or in combination, may potentially provide novel approaches to treat metastatic GI malignancies.

Abstract
Lysosomal-associated transmembrane protein 5 (LAPTM5) has been associated with poor prognosis in cancer patients. Its role in regulating metastasis in pancreatic ductal adenocarcinoma (PDAC), however, remains vague. The study here aimed to expound the metastasis-promoting properties of LAPTM5 in PDAC and the detailed mechanism. LAPTM5 was overexpressed in metastatic PDAC cells and was related to the dismal prognosis of patients in GEO datasets. By using lentiviral vectors harboring short hairpin RNA, we found that LAPTM5 downregulation reduced PDAC cell viability, proliferation, and aggressiveness in vitro and liver metastasis in vivo. Zinc finger with KRAB and SCAN domains 5 (ZKSCAN5) was predicted and verified to mediate LAPTM5 transcription in PDAC cells. Both ZKSCAN5 and SET domains, containing lysine methyltransferase 7 (SETD7) bound to the LAPTM5 promoter, and ZKSCAN5 recruited SETD7 to form a complex promoting LAPTM5 transcription. LAPTM5 knockdown reversed the promoting effect of ZKSCAN5 on the metastasis of PDAC cells. Thus, our findings on the ZKSCAN5/SETD7/LAPTM5 axis provide insights into the underlying mechanism of liver metastasis dissemination in PDAC.

Abstract
Although macrophages contribute to cancer cell dissemination, immune evasion, and metastatic outgrowth, they have also been reported to coordinate tumor-specific immune responses. We therefore hypothesized that macrophage polarization could be modulated therapeutically to prevent metastasis. Here, we show that macrophages respond to β-glucan (odetiglucan) treatment by inhibiting liver metastasis. β-glucan activated liver-resident macrophages (Kupffer cells), suppressed cancer cell proliferation, and invoked productive T cell-mediated responses against liver metastasis in pancreatic cancer mouse models. Although excluded from metastatic lesions, Kupffer cells were critical for the anti-metastatic activity of β-glucan, which also required T cells. Furthermore, β-glucan drove T cell activation and macrophage re-polarization in liver metastases in mice and humans and sensitized metastatic lesions to anti-PD1 therapy. These findings demonstrate the significance of macrophage function in metastasis and identify Kupffer cells as a potential therapeutic target against pancreatic cancer metastasis to the liver.

Abstract
Case studies of rare oncologic metastases are an important source of clinical data for health care professionals and researchers. While infrequent, the knowledge base and clinical recommendations derived from such cases aid in advancements in the field. As such, we aim to add five cases to the growing body of literature. The first two male patients, aged 69 and 73, were diagnosed with colon adenocarcinoma, suspected to be a second primary prostate carcinoma, following positron emission tomography-computer tomography (PET-CT). This suspicion was ruled out by prostatectomy and histopathological investigations, which instead found adenocarcinoma of colonic origin. The next two male patients, ages 63 and 68, were diagnosed, respectively, with metastatic pancreatic adenocarcinoma with cardiac metastases and metastatic melanoma with distant metastases to the pancreas. The final patient was a 73-year-old male diagnosed with metastatic breast cancer after a radiological investigation of suspected renal cell carcinoma.

Abstract
Pancreatic adenocarcinoma (PDAC) is well known for its poor survival time. Clinical symptoms are painless jaundice or abdominal or back pain. Less specific symptoms often appear that make diagnosis difficult, e.g., weight loss, loss of appetite, nausea and vomiting, and general weakness. Only 10-20% of patients are diagnosed at an early stage. A cure is practically only possible with a radical surgical operation. In the case of locally advanced findings, neoadjuvant therapy is administered. Among the therapeutic options offered are chemotherapy, radiotherapy (including stereotactic radiotherapy-SBRT), targeted treatment, or immunotherapy. In the case of metastatic disease, of which more than half are present at diagnosis, the goal is to relieve the patient of problems. Metastatic PDAC can cause problems arising from the localization of distant metastases, but it also locally affects the organs it infiltrates. In our review article, we focus on the largest group of patients, those with locally advanced disease and metastatic disease-symptoms related to the infiltration or destruction of the pancreatic parenchyma and the growth of the tumor into the surrounding. Therefore, we deal with biliary or duodenal obstruction, gastric outlet syndrome, bleeding and thromboembolic diseases, pain, depression, and fatigue, as well as pancreatic exocrine insufficiency and malnutrition. Metastatic spread is most often to the liver, peritoneum, or lungs. The presented overview aims to offer current therapeutic options across disciplines. In accordance with modern oncology, a multidisciplinary approach with a procedure tailored to the specific patient remains the gold standard.

Abstract
Liver metastases remain a major obstacle for the management of all types of tumors arising from digestive organs, and the tumor microenvironment has been regarded as an important factor in metastasis. To discover herbal candidates inhibiting the liver metastasis of tumors originating from the digestive system via the modulation of the tumor microenvironment and liver environment, we searched three representative public databases and conducted a systematic review. A total of 21 studies that employed experimental models for pancreatic (9), colon (8), and stomach cancers (4) were selected. The herbal agents included single-herb extracts (5), single compounds (12), and multiherbal decoctions (4). Curcuma longa Linn was most frequently studied for its anti-colon-liver metastatic effects, and its possible mechanisms involved the modulation of tumor microenvironment components such as vascular endothelial cells and immunity in both tumor tissues and circulating cells. The list of herbal agents and their mechanisms produced in this study is helpful for the development of anti-liver metastasis drugs in the future.

Abstract
BACKGROUND Nearly one fourth of patients with pancreatic ductal adenocarcinoma (PDAC) occur to liver metastasis after surgery, and liver metastasis is a risk factor for prognosis for those patients with surgery therapy. However, there is no effective way to predict liver metastasis post-operation. METHOD Clinical data and preoperative magnetic resonance imaging (MRI) of PDAC patients diagnosed between July 2010 and July 2020 were retrospectively collected from three hospital centers in China. The significant MRI radiomics features or clinicopathological characteristics were used to establish a model to predict liver metastasis in the development and validation cohort. RESULTS A total of 204 PDAC patients from three hospital centers were divided randomly (7:3) into development and validation cohort. Due to poor predictive value of clinical features, MRI radiomics model had similar receiver operating characteristics curve (ROC) value to clinical-radiomics combing model in development cohort (0.878 vs. 0.880, p = 0.897) but better ROC in validation dataset (0.815 vs. 0.732, p = 0.022). Radiomics model got a sensitivity of 0.872/0.750 and a specificity of 0.760/0.822 to predict liver metastasis in development and validation cohort, respectively. Among 54 patients randomly selected with post-operation specimens, fibrosis markers (α-smooth muscle actin) staining was shown to promote radiomics model with ROC value from 0.772 to 0.923 (p = 0.049) to predict liver metastasis. CONCLUSION This study developed and validated an MRI-based radiomics model and showed a good performance in predicting liver metastasis in resectable PDAC patients.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Qingyihuaji Formula (QYHJ), a widely used traditional Chinese medicine (TCM), has been used to treat patients with cancer in China. However, the effect and mechanism of QYHJ on pancreatic ductal adenocarcinoma (PDAC) remains unclear. AIM OF THE STUDY This study aimed to explore the roles and evaluate the possible underlying molecular mechanisms of QYHJ and its core component in PDAC using label-free quantitative proteomics in conjunction with network pharmacology-based analysis. MATERIALS AND METHODS By screening differentially expressed proteins (DEPs) in proteomics and QYHJ-predicted gene sets, we identified QYHJ-related PDAC targets annotated with bioinformatic analysis. A subcutaneous tumor model was established to assess the role of QYHJ in vivo. The effects of quercetin (Que), a core component of QYHJ, on cell proliferation, migration, invasion, apoptosis, and autophagy in SW1990 and PANC-1 cells were investigated in vitro. Immunohistochemistry, western blotting, mRFP-GFP-LC3 adenovirus, and kinase analysis were used to determine the underlying mechanisms. RESULTS Bioinformatics analysis revealed that 41 QYHJ-related PDAC targets were closely related to the cellular response to nitrogen compounds, positive regulation of cell death, regulation of epithelial cell apoptotic processes, and chemokine signaling pathways. CASP3, SRC, STAT1, PTPN11, PKM, and PAK1 with high expression were identified as hub DEPs in the PPI network, and these DEPs were associated with poor overall survival and STAT 1, MAPK/ERK, and PI3K/Akt/mTOR signaling pathways in PDAC patients. QYHJ significantly promoted tumor death in nude mice. Moreover, quercetin inhibited the proliferation, migration, and invasion of PDAC cells. Additionally, Que induced apoptosis and autophagy in PDAC cells. Mechanistically, QYHJ and Que significantly activated STAT 1 and remarkably inhibited the MAPK/ERK and PI3K/Akt/mTOR signaling pathways in vivo and in vitro, respectively. Importantly, ERK1/2 inactivation contributes to que-induced apoptosis in SW1990 and PANC-1 cells. CONCLUSIONS These results suggest that QYHJ and Que are promising anti-PDAC avenues that benefit from their multiform mechanisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wuwei Shexiang Pills (WWSX), a classic Tibetan medicine, consists of Chebulae Fructus (removed pit), Aucklandiae Radix, Moschus, Aconiti Fiavi Radix, and Acori Calami Rhizoma. It is used clinically in China to treat joint pain, swelling and other symptoms, and has the function of dispelling wind and relieving pain. However, to date, the mechanism of how it works against gout is still unclear. AIMS OF THE STUDY Using network pharmacology, molecular docking and pharmacological verification to explore the potential anti-gout properties of WWSX. MATERIALS AND METHODS With the use of UPLC-Q/TOF-MS, the main components of WWSX were obtained and screened for potential anti-inflammatory components by network pharmacology and molecular docking. The anti-inflammatory activity of the components screened from WWSX was also tested by in vitro assays. The anti-gout mechanism of WWSX was predicted by network pharmacology, and the pharmacological validation experiments using gouty arthritis model and mouse air pouch model were used to explore the multifaceted mechanism of WWSX to modify gout. RESULT Thirty-eight active ingredients were obtained from the UPLC-Q/TOF-MS detection. The network pharmacology and molecular docking analysis showed that 104 co-targets were participated in the treatment of gout, and the main signaling pathways involved were NOD-like receptor pathway, NF-κB pathway and MAPK pathway. Pharmacological evaluation showed that WWSX could significantly improve gout in gouty arthritis models and mouse air pouch models by modulating the above pathways. CONCLUSION This work has predicted and validated the anti-inflammatory material basis and predicted the anti-gout mechanism of WWSX which was verified by network pharmacology, molecular docking and in vitro cellular studies. The results reveal the mechanism of WWSX in the treatment of gout and provide a theoretical basis for its clinical application.

Abstract
Surgical extirpation of liver tumors remains a proven approach in the management of metastatic tumors to the liver, particularly those of colorectal origin. Ablative, non-resective therapies are an increasingly attractive primary therapy for liver tumors as they are generally better tolerated and result in far less morbidity and mortality. Ablative therapies preserve greater normal liver parenchyma allowing better post-treatment liver function and are particularly appropriate for treating subsequent liver-specific tumor recurrence. This article reviews the current status of ablative therapies for non-hepatocellular liver tumors with a discussion of many of the clinically available approaches.

Exploration of the System-Level Mechanisms of the Herbal Drug FDY003 for Pancreatic Cancer Treatment: A Network Pharmacological Investigation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:7160209. [PMID: 35591866 PMCID: PMC9113891 DOI: 10.1155/2022/7160209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 04/12/2022] [Indexed: 11/18/2022]
Abstract
Pancreatic cancer (PC) is the most lethal cancer with the lowest survival rate globally. Although the prescription of herbal drugs against PC is gaining increasing attention, their polypharmacological therapeutic mechanisms are yet to be fully understood. Based on network pharmacology, we explored the anti-PC properties and system-level mechanisms of the herbal drug FDY003. FDY003 decreased the viability of human PC cells and strengthened their chemosensitivity. Network pharmacological analysis of FDY003 indicated the presence of 16 active phytochemical components and 123 PC-related pharmacological targets. Functional enrichment analysis revealed that the PC-related targets of FDY003 participate in the regulation of cell growth and proliferation, cell cycle process, cell survival, and cell death. In addition, FDY003 was shown to target diverse key pathways associated with PC pathophysiology, namely, the PIK3-Akt, MAPK, FoxO, focal adhesion, TNF, p53, HIF-1, and Ras pathways. Our network pharmacological findings advance the mechanistic understanding of the anti-PC properties of FDY003 from a system perspective.

Abstract
PURPOSE To assess the impact of periprocedural factors, including adverse events, on overall patient survival following image-guided liver tumor cryoablation procedures. METHODS In this retrospective single-institution study, 143 patients (73 male, 70 female, ages 29-88) underwent 169 image-guided liver tumor cryoablation procedures between October 1998 and August 2014. Patient, tumor and procedural variables were recorded. The primary outcome was overall survival post-procedure (Kaplan-Meier analysis). Secondary outcomes were the impact of 15 variables on patient survival, which were assessed with multivariate cox regression and log-rank tests. RESULTS Mean tumor diameter was 2.5 ± 1.2 cm. 26 of 143 (18.2%) patients had primary hepatic malignancies; 117 of 143 (81.8%) had liver metastases. Survival analysis revealed survivor functions at 3, 5, 7, 10 and 12 years post-ablation of 0.54, 0.37, 0.30, 0.17 and 0.06, with mean survival time of 40.8 ± 4.9 months. Tumor size ≥4 cm (p = .018), pre-procedural platelet count <100 × 103/μL (p = .023), and prior local radiation therapy (p = .014) were associated with worse overall patient survival. Grade 3 or higher adverse events were not associated with reduced survival (p = .49). CONCLUSIONS All variables associated with overall survival were patient-related and none were associated with the cryoablation procedure. Pre-procedural thrombocytopenia, larger tumor size and history of prior local radiation therapy were independent risk factors for reduced overall survival in patients undergoing hepatic cryoablation. Adverse events related to hepatic cryoablation were not associated with decreased survival.

Liver Metastasis-Directed Ablative Radiotherapy in Pancreatic Cancer Offers Prolonged Time Off Systemic Therapy in Selected Patients: Data From a Multi-institutional Retrospective Study. Pancreas 2021; 50:736-743.

Abstract
OBJECTIVES We evaluated the outcomes of metastatic pancreatic cancer (MPC) patients who underwent liver metastases (LMs)-directed ablative radiotherapy (RT) and sought to characterize patients with more favorable prognosis. METHODS A retrospective analysis of 76 MPC patients who underwent ablative RT (median dose, 50 Gy) to LM at 3 academic centers between 2008 and 2018 was performed. Endpoints were local control (LC), progression-free survival, and overall survival (OS) since RT. RESULTS Median follow-up was 10.9 months. Liver metastases were metachronous in 68%. Before RT, LM was responsive/stable on chemotherapy (CTX) in 36% whereas progressive in 43%. Median carbohydrate antigen 19-9 (CA 19-9) at RT was 334 U/mL. After RT, 32% had ≥6 months of CTX break. Twelve-month outcomes were: LC, 66%; progression-free survival, 7%; and OS, 38%. On multivariable analysis, Eastern Cooperative Oncology Group 2-3 (hazard ratio [HR], 13.49; P < 0.01), progressive LM on CTX (HR, 3.26; P < 0.01), and higher CA 19-9 (log10 scale; HR, 1.39; P < 0.01) at RT predicted worse OS. CONCLUSIONS Ablative RT to LM in setting of MPC may offer LC of systemic disease and thus quality time off CTX. Selected patients with good performance status, stable/responsive LM on CTX, and lower CA 19-9 have more favorable prognosis.

Abstract
Liver metastases are commonly detected in a range of malignancies including colorectal cancer (CRC), pancreatic cancer, melanoma, lung cancer and breast cancer, although CRC is the most common primary cancer that metastasizes to the liver. Interactions between tumour cells and the tumour microenvironment play an important part in the engraftment, survival and progression of the metastases. Various cells including liver sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, parenchymal hepatocytes, dendritic cells, resident natural killer cells as well as other immune cells such as monocytes, macrophages and neutrophils are implicated in promoting and sustaining metastases in the liver. Four key phases (microvascular, pre-angiogenic, angiogenic and growth phases) have been identified in the process of liver metastasis. Imaging modalities such as ultrasonography, CT, MRI and PET scans are typically used for the diagnosis of liver metastases. Surgical resection remains the main potentially curative treatment among patients with resectable liver metastases. The role of liver transplantation in the management of liver metastasis remains controversial. Systemic therapies, newer biologic agents (for example, bevacizumab and cetuximab) and immunotherapeutic agents have revolutionized the treatment options for liver metastases. Moving forward, incorporation of genetic tests can provide more accurate information to guide clinical decision-making and predict prognosis among patients with liver metastases.

Abstract
DNA replication inhibitors are utilized extensively in studies of molecular biology and as chemotherapy agents in clinical settings. The inhibition of DNA replication often triggers double-stranded DNA breaks (DSBs) at stalled DNA replication sites, resulting in cytotoxicity. In East Asia, some traditional medicines are administered as anticancer drugs, although the mechanisms underlying their pharmacological effects are not entirely understood. In this study, we screened Japanese herbal medicines and identified two benzylisoquinoline alkaloids (BIAs), berberine and coptisine. These alkaloids mildly induced DSBs, and this effect was dependent on the function of topoisomerase I (Topo I) and MUS81-EME1 structure-specific endonuclease. Biochemical analysis revealed that the action of BIAs involves inhibiting the catalytic activity of Topo I rather than inducing the accumulation of the Topo I-DNA complex, which is different from the action of camptothecin (CPT). Furthermore, the results showed that BIAs can act as inhibitors of Topo I, even against CPT-resistant mutants, and that the action of these BIAs was independent of CPT. These results suggest that using a combination of BIAs and CPT might increase their efficiency in eliminating cancer cells.

Abstract
OPINION STATEMENT Despite extensive research that has identified new risk factors, genetic mutations, and therapeutic options, pancreatic ductal adenocarcinoma continues to be a leading cause of cancer related death. Patients with pancreatic cancer, along with their clinicians, must balance realistic hope alongside a life-threatening diagnosis. As the search for treatments to reduce the morbidity and mortality continues, symptom management and quality of life remain the focus of our efforts. In addition to side effects of cancer-directed therapy, patients are at risk for malnutrition, pain, and fatigue. These factors are often overlooked in practice, so a multidisciplinary team is critical in optimizing the care of patients.

Abstract
The study aimed to clarify the potential immune-related targets and mechanisms of Qingyihuaji Formula (QYHJ) against pancreatic cancer (PC) through network pharmacology and weighted gene co-expression network analysis (WGCNA). Active ingredients of herbs in QYHJ were identified by the TCMSP database. Then, the putative targets of active ingredients were predicted with SwissTargetPrediction and the STITCH databases. The expression profiles of GSE32676 were downloaded from the GEO database. WGCNA was used to identify the co-expression modules. Besides, the putative targets, immune-related targets, and the critical module genes were mapped with the specific disease to select the overlapped genes (OGEs). Functional enrichment analysis of putative targets and OGEs was conducted. The overall survival (OS) analysis of OGEs was investigated using the Kaplan-Meier plotter. The relative expression and methylation levels of OGEs were detected in UALCAN, human protein atlas (HPA), Oncomine, DiseaseMeth version 2.0 and, MEXPRESS database, respectively. Gene set enrichment analysis (GSEA) was conducted to elucidate the key pathways of highly-expressed OGEs further. OS analyses found that 12 up-regulated OGEs, including CDK1, PLD1, MET, F2RL1, XDH, NEK2, TOP2A, NQO1, CCND1, PTK6, CTSE, and ERBB2 that could be utilized as potential diagnostic indicators for PC. Further, methylation analyses suggested that the abnormal up-regulation of these OGEs probably resulted from hypomethylation, and GSEA revealed the genes markedly related to cell cycle and proliferation of PC. This study identified CDK1, PLD1, MET, F2RL1, XDH, NEK2, TOP2A, NQO1, CCND1, PTK6, CTSE, and ERBB2 might be used as reliable immune-related biomarkers for prognosis of PC, which may be essential immunotherapies targets of QYHJ.

Abstract
OBJECTIVES We investigated whether the combination of systemic chemotherapy (SCT) and liver-directed therapy (LDT) was superior to chemotherapy alone for patients with pancreatic adenocarcinoma and synchronous liver metastases (PACLM). METHODS We reviewed the medical records of 184 patients treated with SCT ± LDT at Tianjin Medical University Cancer Hospital from 2001 to 2015. Overall survival (OS) was the primary end-point. The role of treatment modality and other clinical factors was evaluated by univariate and Cox regression analyses. RESULTS Sixty-four (34.8%) patients in the SCT-LDT group and 120 (65.2%) patients in the SCT group were included in the analysis. Baseline clinical characteristics were similar between the groups (all P > 0.05). The median survival was 8.7 months in the SCT-LDT group and was 6.3 months in the SCT group. The 0.5-, 1-, 2- and 3-year survival rates were 67.2%, 33.4%, 13.3% and 8.9%, respectively, after SCT-LDT, and were 54.9%, 19.0%, 4.5% and 2.0%, respectively, after SCT (P = 0.01). Primary tumor size, ascites, and treatment modality (SCT + LDT vs. SCT) independently predicted survival (P < 0.05). The clinical efficacy congruously favored the SCT-LDT group across the majority of subgroups. CONCLUSIONS SCT combined with LDT was well tolerated and may be effective to improve survival of patients with PACLM. Ascites and large primary tumor size were poor prognostic factors associated with survival.

Abstract
Busulfan is an anti-cancer chemotherapeutic drug and is often used as conditioning regimens prior to bone marrow transplant for treatment of chronic myelogenous leukemia. Male infertility, including spermatogenesis disturbance, is known to be one of the side effects of anticancer drugs. While hormone preparations and vitamin preparations are used for spermatogenesis disturbance, their therapeutic effects are low. Some traditional herbal medicines have been administered to improve spermatogenesis. In the present study, we administered Gosha-jinki-gan (TJ107; Tsumura Co., Ltd., Tokyo, Japan) to mice suffering from severe aspermatogenesis after busulfan treatment to determine whether TJ107 can recover spermatogenesis. Male 4-week-old C57BL/6J mice were administered a single intraperitoneal injection of busulfan, and they were then fed a normal diet for 60 days and then a TJ107 diet or TJ107-free normal diet for another 60 days. After busulfan treatment, the weight of the testes and the epididymal sperm count progressively decreased in the normal diet group. On the other hand, in the TJ107 group, these variables dramatically recovered at 120 days. These results suggest that busulfan-induced aspermatogenesis is irreversible if appropriate treatment is not administered. Supplementation of TJ107 can completely recover the injured seminiferous epithelium via normalization of the macrophage migration and reduction of the expressions of Tool-like receptor (TLR) 2 and TLR4, suggesting that TJ107 has a therapeutic effect on busulfan-induced aspermatogenesis.

Abstract
Recent studies have suggested that sonic Hedgehog (Shh) signaling pathway is aberrantly activated in cancer stem cells (CSCs). A seven-herb Chinese medicinal formula composed of Amorphophallus rivieri Durieu, Oldenlandia diffusa (Wild) Roxb, Scutellaria barbata D. Don, Gynostemma pentaphyllum (Thunb.) Mak and Amomum cardamomum L, i.e. Qingyihuaji (QYHJ) formula, has been shown to inhibit proliferation of pancreatic CSCs by inhibiting Shh signaling pathway and thereby prolong the overall survival of pancreatic cancer patients. Mass spectrometry analysis revealed that baicalein is one of the major compounds of QYHJ formula. The objective of this study was to investigate the role of Shh pathway in pancreatic cancer and to examine the molecular mechanisms of baicalein involved in pancreatic cancer treatment. We examined the effects of baicalein on pancreatic CSCs both in vivo and in vitro. The results indicated that baicalein attenuated the pluripotency of pancreatic CSCs. Then, we investigated the underlying mechanism and found that nuclear transcription factors, such as Sox-2 and Oct-4 as well as members in Shh signaling pathway, e.g. SHH, SMO, and Gli-2, were downregulated after baicalein treatment. Furthermore, silencing Gli-2 expression by small interfering RNA decreased Sox-2 expression and blocked the inhibitory effects of baicalein, suggesting that the effects of baicalein may be mediated through inhibition of Shh pathway. Our results suggested that baicalein, an active compound in QYHJ formula, could suppress the self-renewal of pancreatic CSCs through inhibition of Shh signaling pathway.

Abstract
Traditional Chinese medicine (TCM) is one of the most common complementary and alternative medicines used in the treatment of patients with cancer worldwide. However, the clinical effect of TCM on patients with pancreatic cancer remains unclear. This study was aimed to explore the efficacy of TCM on selected patients with pancreatic cancer and to study the usefulness of multimodality treatment, including TCM and western medicine (WM), in pancreatic cancer.From January 2009 to October 2013, 107 patients with pancreatic cancer were included in this study. Kaplan-Meier curves were used to assess the differences in survival time. Cox regression analysis was performed to determine survival trends adjusted for clinical and demographic factors.Cox regression analysis suggested that elevated CA19-9 levels (P = 0.048), number of cycles of chemotherapy (P = 0.014), and TCM were independent prognostic factors (P < 0.001). The survival hazards ratio of TCM was 0.419 (95% confidence interval [CI], 0.261-0.671). The median overall survival (OS) was 19 months for patients with TCM treatment, while the median OS was 8 months for those without TCM treatment (P < 0.001). Patients who received multimodality treatment using TCM and WM had the best prognosis with a median OS of 19 months (P < 0.001). Patients with heat-clearing, diuresis-promoting and detoxification TCM treatment had a longer survival time (32.4 months) than those with blood-activating and stasis-dissolving (9.8 months) and tonifying qi and yang treatment (6.1 months; P = 0.008).These results indicate that TCM has an important potential value for improving the prognosis of patients with pancreatic cancer, and multimodality treatment, including TCM and WM, leads to the best prognosis. More importantly, we suggest that heat-clearing, diuresis-promoting, and detoxification TCM treatment may improve the efficacy of TCM in pancreatic cancer.

Abstract
OBJECTIVE To investigate, in terms of Notch signaling pathway, the effect on pancreatic cancer of the extract of an anti-tumor prescription--Qingyi-huaji formula (QYHJ)--from Traditional Chinese Medicine (TCM). METHODS Nude mice were implanted subcutaneously with human pancreatic cancer cell line SW1990 and then randomly divided into four groups: Control, QYHJ extract, Gemcitabine, and Combination of QYHJ extract and gemcitabine. Treatments were given for 21 days and tumor growth was evaluated simultaneously. Then, expression of Notch receptors (Notch-1, Notch-2, Notch-3, and Notch-4) and their Jagged ligands (Jagged-1 and Jagged-2) in dissected tumor tissue were detected by real-time quantitative reverse transcription-polymerase chain reaction and Western blot. Finally, immunohistochemistry was performed to detect CD133, a marker of pancreatic cancer stem cells (CSCs), to evaluate the impact of QYHJ extract on pancreatic CSCs. RESULTS QYHJ extract treatment effectively inhibited the tumor growth in nude mice. The expression of both Notch-4 and Jagged-1 were decreased significantly in QYHJ treatment groups (P < 0.05), while gemcitabine alone had no significant effect in down-regulating Jagged-1 (P > 0.05). No significant difference was observed in the ex- pression of Notch-1, Notch-2, Notch-3, and Jagged-2 between three treatment groups and control group (P > 0.05). Moreover, immunohistochemical analysis showed that the number of CD133 positive cells was significantly reduced by QYHJ treatment (P < 0.05), and the combined treatment was more effective than gemcitabine alone (P < 0.05). CONCLUSION The role of the extract in pancreatic cancer treatment was associated with down-regulation of Notch-4 and Jagged-1 in Notch signaling pathway. The extract could enhance the antitumor activity of gemcitabine and was more effective than gemcitabine in regulating Notch signaling pathway to some extent.

Abstract
Pancreatic cancer has a poor prognosis with a 5-year survival rate of <5%. It does not respond well to either chemotherapy or radiotherapy, due partly to apoptotic resistance (AR) of the cancer cells. AR has been attributed to certain genetic abnormalities or defects in apoptotic signaling pathways. In pancreatic cancer, significant mutations of K-ras and p53, constitutive activation of NFκB, over-expression of heat shock proteins (Hsp90, Hsp70), histone deacetylase (HDACs) and the activities of other proteins (COX-2, Nrf2 and bcl-2 family members) are closely linked with resistance to apoptosis and invasion. AR has also been associated with aberrant signaling of MAPK, PI3K-AKT, JAK/STAT, SHH, Notch, and Wnt/β-catenin pathways. Strategies targeting these signaling molecules and pathways provide an alternative for overcoming AR in pancreatic cancer. The use of herbal medicines or natural products (HM/NPs) alone or in combination with conventional anti-cancer agents has been shown to produce beneficial effects through actions upon multiple molecular pathways involved in AR. The current standard first-line chemotherapeutic agents for pancreatic cancer are gemcitabine (Gem) or Gem-containing combinations; however, the efficacy is dissatisfied and this limitation is largely attributed to AR. Meanwhile, emerging data have pointed to a combination of HM/NPs that may augment the sensitivity of pancreatic cancer cells to Gem. Greater understanding of how these compounds affect the molecular mechanisms of apoptosis may propel development of HM/NPs as anti-cancer agents and/or adjuvant therapies forward. In this review, we give a critical appraisal of the use of HM/NPs alone and in combination with anti-cancer drugs. We also discuss the potential regulatory mechanisms whereby AR is involved in these protective pathways.

Abstract
The treatment of cancer draws interest from researchers worldwide. Of the different extracts from traditional Chinese medicines, Tubeimoside 1 (TBMS 1) is regarded as an effective treatment for cancer. To determine the mechanism of TBMS 1, the shape/pattern of HepG2 cells based on the microscopic imaging technology was determined to analyze experimental results; then the fluorescent spectra method was designed to investigate whether TBMS 1 affected HepG2 cells. A three-dimensional (3D) fluorescent spectra sweep was performed to determine the characteristic wave peak of HepG2 cells. A 2D fluorescent spectra method was then used to show the florescence change in HepG2 cells following treatment with TBMS 1. Finally, flow cytometry was employed to analyze the cell cycle of HepG2 cells. It was shown that TBMS 1 accelerated the death of HepG2 cells and had a strong dose- and time-dependent growth inhibitory effect on HepG2 cells, especially at the G2/M phase. These results indicate that the fluorescent spectra method is a promising substitute for flow cytometry as it is rapid and cost-effective in HepG2 cells.

Oncol Lett 2014; 8:17-24.

Abstract
Our previous study demonstrated that inhibition of erythropoietin-producing hepatoma cell line-B2 (EphB2) expression resulted in the promotion of cancer growth, with EphB2 acting as a tumor suppressor in pancreatic cancer. Qingyihuaji formula (QYHJ), a traditional Chinese medicine, acts as an independent protective factor for pancreatic cancer patient survival and different patients have shown various responses to QYHJ treatment. In the current study, the different effects on tumor growth inhibition following QYHJ treatment in cells with different levels of EphB2 expression were investigated to reveal the mechanism. A subcutaneously transplanted tumor model using cancer cells with different levels of EphB2 expression were established in vivo and received a four-week QYHJ intervention. Tumor weight inhibitory rate and tumor volume deflation were evaluated. The cell cycle and apoptosis were analyzed by flow cytometry, and reverse transcription polymerase chain reaction and western blot analysis were used to assess mRNA and protein levels. The results showed that the tumor weight inhibitory rate was 31.40, 31.33 and 18.36% in CFPAC-1, CFPAC-1 control RNAi and CFPAC-1 EphB2 RNAi cells following QYHJ treatment, respectively. A statistically significant difference was identified in CFPAC-1 (P<0.05) and CFPAC-1 control RNAi (P<0.01) cells. In addition, a statistically significant increase was identified in the G0/G1 phase population (P<0.05) and a statistically significant decrease was identified in the S phase population (P<0.05) in CFPAC-1 and CFPAC-1 control RNAi cells; however, no significant difference was identified in the CFPAC-1 EphB2 RNAi cells following QYHJ treatment. QYHJ upregulated the mRNA and protein level of Eph receptor-interacting B1 (EphrinB1) in the cells that were expressing different levels of EphB2, however, QYHJ did not regulate EphB2 expression. In CFPAC-1 and CFPAC-1 control RNAi cells, the QYHJ treatment resulted in a statistically significant decrease in cyclin-dependent kinase 6 (CDK6) mRNA (P<0.05) and protein (P<0.05) levels. The high expression of EphB2 predicted the superior response rate to the QYHJ treatment through a mechanism of inhibiting the cell cycle by an EphrinB1-EphB2-induced CDK6 decrease in CFPAC-1 cells. Therefore, EphB2 acts as a predictive factor for QYHJ treatment in pancreatic cancer CFPAC-1 cells.

Abstract
Pancreatic cancer remains one of the leading causes of cancer-related deaths, due to aggressive growth, high metastatic rates during the early stage and the lack of an effective therapeutic approach. We previously showed that Qingyihuaji (QYHJ), a seven-herb Chinese medicine formula, exhibited significant anti-cancer effects in pancreatic cancer, associated with modifications in the tumor microenvironment, particularly the inhibition of cancer-associated fibroblast (CAF) activation. In the present study, we generated CAF and paired normal fibroblast (NF) cultures from resected human pancreatic cancer tissues. We observed that CAFs exhibited an enhanced capacity for inducing pancreatic cancer cell migration and invasion compared with NFs, while QYHJ-treated CAFs exhibited decreased migration and invasion-promoting capacities in vitro. The results of further analyses indicated that compared with NFs, CAFs exhibit increased CXCL1, 2 and 8 expression, contributing to the enhanced invasion-promoting capacities of these cells, while QYHJ treatment significantly suppressed CAF proliferation activities and the production of CAF-derived CXCL1, 2 and 8. These in vitro observations were confirmed in mice models of human pancreatic cancer. Taken together, these results suggested that suppressing the tumor-promoting capacity of CAFs through Chinese herbal medicine attenuates pancreatic cancer cell invasion.

Abstract
In recent years combination chemoprevention has been increasingly appreciated and investigated as a viable and effective strategy for cancer management. A plethora of evidence suggests that a combination of agents may afford synergistic (or additive) advantage for cancer management by multiple means, such as by (1) enhancing the bio-availability of chemopreventive agents, (2) modifying different molecular targets, and (3) lowering the effective dose of agent/drug to be used for cancer management. Resveratrol has been shown to afford chemopreventive and therapeutic effects against certain cancers. Recent studies are suggesting that resveratrol may be very useful when given in combination with other agents. The two major advantages of using resveratrol in combination with other agents are synergistically or additively enhancing the efficacy against cancer and limiting the toxicity and side effects of existing therapies. However, concerted and multidisciplinary efforts are needed to identify the most optimal combinatorial strategies.

Abstract
Pancreatic cancer is an almost universally fatal disease resulting from early invasion of adjacent structures and metastasis and the lack of an effective treatment modality. Our previous studies have shown that Qingyihuaji Formula (QYHJ), a seven-herb Chinese medicine formula, had significant anti-cancer effects in pancreatic cancer. Here, we examined the effects of QYHJ on pancreatic cancer cell invasion and metastasis and the potential associated mechanism(s). We found that QYHJ inhibited both tumor growth and metastasis in nude mice with human pancreatic cancer cell xenografts. Further study indicated that QYHJ inhibited epithelial-to-mesenchymal transition (EMT), which is characterized by increased E-cadherin expression and decreased vimentin, N-cadherin and Slug expression. Interleukin 6 (IL-6), a pro-inflammatory cytokine produced mainly by macrophages, could promote cancer cell EMT and invasion. In contrast, treatment with QYHJ inhibited cancer-related inflammation in tumors by decreasing infiltration of tumor-associated macrophages and IL-6 production, thus preventing cell invasion and metastasis. These results suggested that the Chinese herbal medicine QYHJ could inhibit pancreatic cancer cell invasion and metastasis in part by reversing tumor-supporting inflammation.

Methylation-mediated silencing of the miR-124 genes facilitates pancreatic cancer progression and metastasis by targeting Rac1. Oncogene 2013; 33:514-24.

Abstract
Previous studies have demonstrated that microRNA (miRNA) expression is altered in human cancer. However, the molecular mechanism underlying these changes in miRNA expression remains unclear. In this study, we investigated the epigenetic modification of miR-124 genes and the potential function of miR-124 in pancreatic cancer. Using pyrosequencing analysis, we found that miR-124 genes (including miR-124-1, miR-124-2 and miR-124-3) are highly methylated in pancreatic cancer tissues compared with in non-cancerous tissues. Hypermethylation mediated the silencing of miR-124, which was a frequent event in pancreatic duct adenocarcinoma (PDAC). Furthermore, miR-124 downregulation was significantly associated with worse survival of PDAC patients. Functional studies showed that miR-124 inhibited cell proliferation, invasion and metastasis. Furthermore, we characterized Rac1 as a direct target of miR-124, and miR-124 interacted with the 3'-untranslated region of Rac1, which we showed to be a putative tumor promoter in pancreatic cancer. Thus, the miR-124-mediated downregulation of Rac1 led to the inactivation of the MKK4-JNK-c-Jun pathway. Therefore, our study demonstrates that miR-124 is a tumor suppressor miRNA that is epigenetically silenced in pancreatic cancer. Our findings suggest a previously unidentified molecular mechanism involved in the progression and metastasis of pancreatic cancer.

Abstract
BACKGROUND Pancreatic cancer is a devastating disease with dismal prognosis. Large population-based evidence on its survival rate and influence factors is lacking in China. OBJECTIVE This study aimed to depict the demographic factors, tumor characteristics, incidence rate and survival rate of pancreatic cancer cases in urban China. METHODS The demographic factors, tumor characteristics were collected for all the pancreatic cancer cases identified during 2004 to 2009 from the Shanghai Cancer Registry. The survival time was ascertained through linkage of the Shanghai Cancer Registry and the Shanghai Vital Statistics Registry. The deadline of death certificates was the end of December 2012. Kaplan-Meier method and Cox proportional-hazards regression model were used to explore the survival rate and influence factors. RESULTS 11,672 new pancreatic cancer cases were identified among Shanghai residency during 2004 to 2009. The crude incidence rate of pancreatic cancer was increasing from 12.80/100,000 in 2004 to 15.66/100,000 in 2009, while the standardized incidence rate was about 6.70/100,000 and didn't change a lot. The overall 5-year survival rate was 4.1% and the median survival time was 3.9 (95% Confidence Interval (CI) 3.8-4.0) months. Subjects had received surgical resection had improved survival (HR = 0.742, 95% CI: 0.634-0.868) than its counterparts. In adjusted multivariable Cox proportional-hazard models, factors associated with poor survival included older age at diagnosis (age > = 70 years: hazard ratio (HR) = 1.827, 95% CI: 1.614-2.067), male sex (HR = 1.155, 95% CI: 1.041-1.281), distant disease at diagnosis (HR = 1.257, 95% CI: 1.061-1.488), positive lymph node (HR = 1.236, 95% CI: 1.085-1.408), tumor stage (Stage IV HR = 2.817, 95% CI: 2.029-3.909). CONCLUSION The age-adjusted incidence rate was stable and overall survival rate was low among pancreatic cancer patients of Shanghai residency. Early detection and improved treatment strategies are needed to improve prognosis for this deadly disease.

The impact of simultaneous liver resection for occult liver metastases of pancreatic adenocarcinoma. Gastroenterol Res Pract 2012; 2012:939350. [PMID: 23258977 PMCID: PMC3508736 DOI: 10.1155/2012/939350] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2012] [Accepted: 10/04/2012] [Indexed: 12/16/2022] Open
Abstract
Backround. Pancreas resection is the only curative treatment for pancreatic adenocarcinoma. In the event of unexpected incidental liver metastases during operative exploration patients were traditionally referred to palliative treatment arms. With continuous progress in the surgical expertise simultaneous pancreas and liver resections seem technically feasible nowadays. The aim of this study therefore was to analyze the impact of synchronous liver-directed therapy on operative outcome and overall survival in patients with hepatic metastasized pancreatic adenocarcinoma (HMPA). Methods. 22 patients who underwent simultaneous pancreas resection and liver-directed therapy for HMPA between January 1, 2004 and January 1, 2009 were compared to 22 patients who underwent classic pancreas resection for nonmetastasized pancreatic adenocarcinoma (NMPA) in a matched pair study design. Postoperative morbidity, preoperative, and operative data and overall survival were analyzed. Results. Overall survival was significantly decreased in the HMPA group. Postoperative morbidity and mortality and median operation time did not significantly differ between the groups. Conclusion. The results of our study showed that simultaneous pancreas resection and liver-directed therapy may safely be performed and may therefore be applied in individual patients with HMPA. However, a potential benefit of this radical surgical approach with regard to overall survival and/or quality of life remains to be proven.

The serum miR-21 level serves as a predictor for the chemosensitivity of advanced pancreatic cancer, and miR-21 expression confers chemoresistance by targeting FasL. Mol Oncol 2012.

Abstract
miR-21 expression in cancer tissue has been reported to be associated with the clinical outcome and activity of gemcitabine in pancreatic cancer. However, resection is possible in only a minority of patients due to the advanced stages often present at the time of diagnosis, and safely obtaining sufficient quantities of pancreatic tumor tissue for molecular analysis is difficult at the unresectable stages. In this study, we investigated whether the serum level of miR-21 could be used as a predictor of chemosensitivity. We tested the levels of serum miR-21 in a cohort of 177 cases of advanced pancreatic cancer who received gemcitabine-based palliative chemotherapy. We found that a high level of miR-21 in the serum was significantly correlated with a shortened time-to-progression (TTP) and a lower overall survival (OS). The serum miR-21 level was an independent prognostic factor for both the TTP and the OS (HR 1.920; 95% CI, 1.274-2.903, p = 0.002 for TTP and HR 1.705; 95% CI, 1.147-2.535, p = 0.008 for OS). The results from a functional study showed that gemcitabine exposure down-regulated miR-21 expression and up-regulated FasL expression. The increased FasL expression following gemcitabine treatment induced cancer cell apoptosis, whereas the ectopic expression of miR-21 partially protected the cancer cells from gemcitabine-induced apoptosis. Additionally, we confirmed that FasL was a direct target of miR-21. Therefore, the serum level of miR-21 may serve as a predictor of chemosensitivity in advanced pancreatic cancer. Additionally, we identified a new mechanism of chemoresistance mediated by the effects of miR-21 on the FasL/Fas pathway.

Emerging glycolysis targeting and drug discovery from chinese medicine in cancer therapy. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:873175. [PMID: 22844340 PMCID: PMC3403522 DOI: 10.1155/2012/873175] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/31/2011] [Revised: 05/28/2012] [Accepted: 06/12/2012] [Indexed: 02/04/2023]
Abstract
Molecular-targeted therapy has been developed for cancer chemoprevention and treatment. Cancer cells have different metabolic properties from normal cells. Normal cells mostly rely upon the process of mitochondrial oxidative phosphorylation to produce energy whereas cancer cells have developed an altered metabolism that allows them to sustain higher proliferation rates. Cancer cells could predominantly produce energy by glycolysis even in the presence of oxygen. This alternative metabolic characteristic is known as the “Warburg Effect.” Although the exact mechanisms underlying the Warburg effect are unclear, recent progress indicates that glycolytic pathway of cancer cells could be a critical target for drug discovery. With a long history in cancer treatment, traditional Chinese medicine (TCM) is recognized as a valuable source for seeking bioactive anticancer compounds. A great progress has been made to identify active compounds from herbal medicine targeting on glycolysis for cancer treatment. Herein, we provide an overall picture of the current understanding of the molecular targets in the cancer glycolytic pathway and reviewed active compounds from Chinese herbal medicine with the potentials to inhibit the metabolic targets for cancer treatment. Combination of TCM with conventional therapies will provide an attractive strategy for improving clinical outcome in cancer treatment.

Tumor Microenvironment Varies under Different TCM ZHENG Models and Correlates with Treatment Response to Herbal Medicine. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:635702. [PMID: 22690248 PMCID: PMC3368347 DOI: 10.1155/2012/635702] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/11/2012] [Accepted: 04/01/2012] [Indexed: 12/13/2022]
Abstract
In traditional Chinese medicine (TCM), diagnosis of pathology and choice of treatment prescriptions are based on a method of differentiation of signs and symptoms known as syndrome differentiation or ZHENG. The cornerstone of TCM, ZHENG, relies on the gathering of clinical information through inspection, auscultation and olfaction, inquiry, and palpation. However, the biomolecular basis of the ZHENG remains unclear. In this study, we established mouse xenograft pancreatic cancer models with Shi-Re (Dampness-Heat), Pi-Xu (Spleen-Deficiency), or Xue-Yu (Blood-Stasis) ZHENG, which are regarded as the three major ZHENGs in pancreatic cancer. We found that tumors of the different ZHENG models exhibited significantly altered cancer-associated fibroblast (CAF) proliferative activity and tumor-associated macrophage (TAM) infiltration, which led to altered levels of CAF- and TAM-derived secreted cytokines such as SDF-1 and CCL5. The ZHENG model type also significantly influenced tumor growth, and administration of herbal medicine to the ZHENG model modified the tumor microenvironment. Therefore, this study partially unveiled the molecular basis of TCM ZHENG in pancreatic cancer.

Abstract
BACKGROUND The 5-year survival rate for patients with pancreatic cancer is <5%, and it is always resistant to the current chemoradiotherapy. Therefore, new, effective agents for the treatment of pancreatic cancer are urgently needed. The promising strategy of cancer-targeting gene virotherapy (CTGVT) has demonstrated great anticancer potential. The objective of the current study was to determine whether 1 CTGVT approach, oncolytic virus (OV)-harboring lipocalin-2, is capable of treating pancreatic cancer. METHODS Tissue microarrays were constructed to detect the expression of lipocalin-2 in 60 specimens of pancreatic adenocarcinoma. The clinical significance of lipocalin-2 was investigated in an analysis of correlations between lipocalin-2 expression and matched clinical characteristics. A lipocalin-2-expressing OV, ZD55-lipocalin-2, was constructed by deleting the adenoviral protein E1B55kD. The antitumor efficacy and mechanisms of the OV were investigated in pancreatic cancer cells with v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations in vitro and in vivo. RESULTS Lipocalin-2 expression was correlated with a good prognosis in patients with pancreatic adenocarcinoma. ZD55-lipocalin-2 dramatically inhibited the growth of pancreatic cancer in vitro and in vivo by inducing cytolysis and caspase-dependent apoptosis. CONCLUSIONS Higher lipocalin-2 expression predicted a better prognosis in patients with pancreatic cancer. The results indicated that ZD55-lipocalin-2, which specifically expressed higher levels of lipocalin-2 in tumor cells, may serve as a potent anticancer drug for pancreatic cancer therapy, especially for patients who have pancreatic adenocarcinoma with KRAS mutations.

Abstract
Recent studies based on epidemiological models published in this journal and elsewhere have demonstrated encouraging patterns suggesting that herbal treatment may improve prognosis in advanced colon and lung cancer patients. Various problems exist with data from nonrandomized studies of this type, but a strong signal of potential positive effect can be seen. The therapeutic mechanisms of traditional Chinese medicine in metastatic cancer are discussed against a hypothetical, dualistic antiproliferation model and immune-stimulation model of tumor progression and regression. Recommendations are made for a strategy to demonstrate more conclusively the efficacy of adjunct herbal treatment during cancer chemotherapy and for discussions with patients until such time as the efficacy trials are completed.

Abstract
UNLABELLED BACKGROUND. Traditional Chinese herbal medicine was associated with improved prognosis in patients with performance score 0-1 at the time of diagnosis of stage IV pulmonary adenocarcinoma (PAC) treated with platinum-based chemotherapy (PBT). OBJECTIVE. The authors investigated the effect of 1- to 4-month lag time to traditional Chinese medicine (TCM) treatment on the median and 1-year survival of PBT-PAC patients. METHODS The median lag time to treatment was 3 months. In the first 3 months, about 35% of the patients died, but thereafter the survival curve flattened off and the death of the next 35% to 40% of patients took 9 months. Leaving out patients with lag time up to 3 months therefore would be a reasonable choice. To be on the safe side, the effects of leaving out patients up to 4 months were investigated. The Kaplan-Meier survival curves were used. RESULTS The median and 1-year survival of the PBT-PAC patients was 5.0 months and 27%, respectively. Leaving out patients with 0-1 month follow-up, 0-2, 0-3, and 0-4 months follow-up changed the median and 1-year survival, respectively, to 5.5 months and 32%, 6.5 months and 36%, 9.0 months and 43%, and 10.0 months and 52%. The median survival of PBT + TCM in PAC patients was 22.6 months and 78%. Median lag time to TCM treatment was 3.0 months. With up to 4 months lag time to treatment due to combined patients' and TCM doctor's waiting time, the improved survival of PBT + TCM performance score 0-1 (fully ambulant) patients at the time of diagnosis still is significant (P < .01, hazard ratio = 0.51). Moreover, the survival of patients treated by TCM doctors with little or more months lag time to treatment was not different (P = .79). CONCLUSION Increasing lag time to treatment up to 4 months improves the median and 1-year survival of PBT patients without TCM but is unlikely to explain the greatly improved prognosis of PBT + TCM treated patients with fully ambulant stage IV PAC.
