ABSTRACT
PURPOSE: To improve patient comfort and reduce complications, clinical benefit of a transradial approach for transcatheter arterial chemoembolization (TACE) was evaluated in patients with hepatocellular carcinoma (HCC). METHODS: A total of 284 patients with HCC for TACE was divided into transradial approach group (n = 126) and transfemoral approach group (n = 158). These two groups of cases were retrospectively compared with regard to complications, the procedural time, X‑ray exposure time, length of hospitalization, and hospital costs. RESULTS: There were lower incidence rates of complications including abdominal distension (42.85% vs. 87.97%, P < 0.001), vomiting (53.17% vs. 77.22%, P < 0.001), lumbago (1.59% vs. 97.46%, P < 0.001), and dysuria (0% vs. 62.03%, P < 0.001) in the transradial group as compared with the transfemoral group. The time required for catheterization and total X‑ray exposure time were less in the transradial group compared with the transfemoral group (Pall < 0.001). The hospital stay time and costs required for catheterization were less in the transradial group compared with the transfemoral group (P < 0.001 and P = 0.001, respectively). In addition, hepatic angiography and TACE were completed in 100% and 99.2% cases in transfemoral and transradial groups, respectively. CONCLUSIONS: Transradial approach for TACE improves quality of life in patients with HCC by offering fewer complications and lower costs compared with transfemoral approach.
ABSTRACT
OBJECTIVE: To systematic review and analysis the clinical efficacy and toxicity of lentinan injection combined with chemotherapy in the treatment of nonsmall cell lung cancer (NSCLC). MATERIALS AND METHODS: The databases of PubMed and CNKI were electronic searched with the free text word of lung cancer/NSCLC and lentinan. The prospective clinical study reporting the clinical efficacy and safety of lentinan injection combined with chemotherapy in the treatment of NSCLC were reviewed and included in this meta‑analysis. The combined treatment efficacy and toxicity of lentinan injection combined with chemotherapy were pooled by Stata 11.0 software. RESULTS: Twelve clinical studies of lentinan injection combined with chemotherapy in the treatment of NSCLC with 458 controls and 492 NSCLCs patients were finally included in this meta‑analysis. The pooled results indicated that the objective response rate was significant improved in the lentinan injection combined chemotherapy group compared with chemotherapy group only (relative risk [RR] = 1.31, 95% confidence interval [CI]: 1.14–1.52). The chemotherapy‑related toxicity of III/IV gastrointestinal reaction (RR = 0.54, 95% CI: 0.43–0.68) and III/IV granulocytopenia (RR = 0.65, 95% CI: 0.51–0.70) were significant decreased in the combined group. CONCLUSION: Lentinan injection combined chemotherapy significant increase the objective response rate and decreased the chemotherapy‑related toxicity.
ABSTRACT
Phosphatidylserine (PS) exposure occurs during the cell death program and fluorescein-labeled lactadherin permits the detection of PS exposure earlier than annexin V in suspended cell lines. Adherent cell lines were studied for this apoptosis-associated phenomenon to determine if PS probing methods are reliable because specific membrane damage may occur during harvesting. Apoptosis was induced in the human tongue squamous carcinoma cell line (Tca8113) and the adenoid cystic carcinoma cell line (ACC-2) by arsenic trioxide. Cells were harvested with a modified procedure and labeled with lactadherin and/or annexin V. PS exposure was localized by confocal microscopy and apoptosis was quantified by flow cytometry. The detachment procedure without trypsinization did not induce cell damage. In competition binding experiments, phospholipid vesicles competed for more than 95 and 90 percent of lactadherin but only about 75 and 70 percent of annexin V binding to Tca8113 and ACC-2 cells. These data indicate that PS exposure occurs in three stages during the cell death program and that fluorescein-labeled lactadherin permitted the detection of early PS exposure. A similar pattern of PS exposure has been observed in two malignant cell lines with different adherence, suggesting that this pattern of PS exposure is common in adherent cells. Both lactadherin and annexin V could be used in adherent Tca8113 and ACC-2 cell lines when an appropriate harvesting procedure was used. Lactadherin is more sensitive than annexin V for the detection of PS exposure as the physical structure of PS in these blebs and condensed apoptotic cell surface may be more conducive to binding lactadherin than annexin V.
