BACKGROUND: Huachansu, a Chinese medicine that comes from dried toad venom from the skin glands of Bufo gargarizans or B. melanostictus, has been used in the treatment of various cancers in China. The authors conducted a pilot study, using a phase 1 trial design, of huachansu in patients with advanced cancer.METHODS: Huachansu was administered intravenously for 14 days followed by 7 days off (1 cycle). Without significant adverse events or progressive disease, treatment continued beyond 2 cycles. The dose of huachansu was escalated as follows with 3 patients per cohort: 10 (level 1), 20 (level 2), 40 (level 3), 60 (level 4), and 90 (level 5) mL/m².RESULTS: Fifteen patients (hepatocellular cancer, n = 11; nonsmall cell lung cancer, n = 2; pancreatic cancer, n = 2) were enrolled in the trial, and no dose‐limiting toxicities (DLTs) were found. Eleven patients had no drug‐related toxicity greater than grade 1. Six (40%) had stable disease (median duration, 6.0 months; range, 3.5‐11.1 months). One of these patients (with hepatocellular cancer) had 20% regression (duration, 11 months) (dose level 1). Quality of life improved for patients with stable disease. Plasma bufalin concentration reached maximal levels at the end of the 2‐hour infusion and was proportional to the amount of drug being administered (0.81‐3.38 ng/mL).CONCLUSIONS: No DLT was observed with the use of huachansu at doses up to 8× higher than typically used in China. Six patients had prolonged stable disease or minor tumor shrinkage. Cancer 2009. © 2009 American Cancer Society.

CXCR1, a receptor for CXCL8/IL-8, has recently been demonstrated to be associated with cancer stem cell (CSC) populations in certain types of human cancers. However, the effect of CXCR1 on CSC and its prognostic value in human pancreatic cancer remain unknown. In this study, we evaluated the expression of CXCR1 in human pancreatic duct adenocarcinoma (PDAC) and found that positive CXCR1 expression correlated with lymph node metastasis (P = 0.017) and a poor survival rate (HR, 3.748; 95% CI, 1.822 to 7.712; P < 0.001) in patients with PDAC. In addition, we identified significant positive correlations between CXCR1 and CD44 (P = 0.002) and CD133 (P = 0.017). Further functional studies confirmed that IL-8 addition increased sphere formation, CSC populations, and cell invasion of pancreatic cancer cells and that these effects could be reversed by antagonizing CXCR1 with a CXCR1-specific antibody. Therefore, our study demonstrated that the IL-8/CXCR1 axis is associated with the CSC-like properties of pancratic cancer cells and prognosis in human pancreatic cancer. This suggested a way of targeting pancreatic CSCs by disrupting IL-8/CXCR1 axis.

Systemic inflammation and immune dysfunction have been proved to be associated with cancer progression and metastasis in various malignancies. The aim of this retrospective study was to evaluate the prognostic significance of pre-treatment systemic immune-inflammation index (SII) in patients with advanced pancreatic cancer. In total, 419 patients diagnosed with advanced pancreatic cancer, between January 2011 and December 2015, were retrospectively enrolled. The SII was developed based on a training set of 197 patients from 2011 to 2013 and validated in an independent cohort of 222 patients from 2014 to 2015. Data on baseline clinicopathologic characteristics; pre-treatment laboratory variables such as absolute neutrophil, lymphocyte, and platelet counts; and carbohydrate antigen 19-9 (CA19-9), total bilirubin (TBIL), albumin (ALB), alkaline phosphatase (ALP), alanine transaminase (ALT), and aspartate transaminase (AST) levels were collected. The association between clinicopathologic characteristics and SII was assessed. The overall survival was calculated using the Kaplan–Meier survival curves and compared using the log-rank test. Univariate and multivariate Cox proportional hazard regression models were used to analyze the prognostic value of the SII. An optimal cutoff point for the SII of 440 stratified the patients with advanced pancreatic cancer into high (> 440) and low (≤ 440) SII groups in the training cohort. Univariate and multivariate analyses revealed that the SII was an independent predictor for overall survival. The prognostic significance of the SII was confirmed in both normal and elevated CA19-9 levels. The baseline SII serves as an independent prognostic marker for patients with advanced pancreatic cancer and can be used in patients with both normal and elevated CA19-9 levels.

Objective: Early detection and prognosis prediction are critical to improve patient survival in pancreatic cancer. This study aimed to investigate whether interleukins could serve as indicators of prognosis in pancreatic cancer. Methods: Sixty-eight patients with pancreatic cancer were enrolled in the study during the period between 2012 and 2014. The serum levels of a broad spectrum of interleukins in these patients were determined, including IL-1β, IL-2, IL-6, IL-8, IL-10, IL-13, IL-15, and IL-23. Results: IL-6, IL-8, and IL-10 showed significant positive correlations with each other. Moreover, high levels of serum IL-6, IL-8, and IL-10 were independently strongly associated with poor survival of patients with pancreatic cancer. Conclusions: Our results suggest that serum levels of IL-6, IL-8, and IL-10 could be useful markers for prediction of prognosis in patients with pancreatic cancer.

BACKGROUND: Xerostomia (dry mouth) after head/neck radiation is a common problem among cancer patients, and available treatments are of little benefit. The objective of this trial was to determine whether acupuncture can prevent xerostomia among head/neck patients undergoing radiotherapy.METHODS: A randomized, controlled trial among patients with nasopharyngeal carcinoma was conducted comparing acupuncture to standard care. Participants were treated at Fudan University Shanghai Cancer Center, Shanghai, China. Forty patients were randomized to acupuncture treatment and 46 to standard care. Patients were treated 3×/wk on the same days they received radiotherapy. Subjective measures included the Xerostomia Questionnaire and MD Anderson Symptom Inventory‐Head and Neck (MDASI‐HN). Objective measures were unstimulated and stimulated whole salivary flow rates. Patients were followed for 6 months after the end of radiotherapy.RESULTS: Xerostomia Questionnaire scores for acupuncture were statistically significantly lower than for controls starting in week 3 through the 6 months (P = .003 at week3, all other P < .0001), with clinically significant differences as follows: week 11, relative risk (RR) 0.63 (95% confidence interval [CI], 0.45‐0.87); 6 months, RR 0.38 (95% CI, 0.19‐0.76). Similar findings were seen for MDASI‐HN scores. Group differences emerged as early as 3 weeks into treatment for saliva (unstimulated whole salivary flow rate, P = .0004), with greater saliva flow in the acupuncture group at week 7 (unstimulated whole salivary flow rate, P < .0001; stimulated whole salivary flow rate, P = .002) and 11 (unstimulated whole salivary flow rate, P < .02; stimulated whole salivary flow rate, P < .03) and at 6 months (stimulated whole salivary flow rate, P < .003).CONCLUSIONS: Acupuncture given concurrently with radiotherapy significantly reduced xerostomia and improved quality of life.
