METHODS: Fifty-eight patients undergoing 79 treatments were retrospectively assessed for development of clinical and laboratory toxicity incidence following ^(90)Y administration. Severe toxicity events were defined using Common Terminology Criteria for Adverse Events version 4.03 and defined as grade ≥ 3. Univariate logistic regression analyses were used to evaluate the effect of different factors on the incidence of severe toxicity events. Multicollinearity was assessed for all factors with P < 0.1 using Pearson correlation matrices. All factors not excluded due to multicollinearity were included in a multivariate logistic regression model for each measurement of severe toxicity.RESULTS: Severe(grade ≥ 3) toxicities occurred following 21.5% of the 79 treatments included in our analysis. The most common severe laboratory toxicities were severe alkaline phosphatase(17.7%), albumin(12.7%), and total bilirubin(10.1%) toxicities. Decreased pre-treatment albumin(OR = 26.2, P = 0.010) and increased pre-treatment international normalized ratio(INR)(OR = 17.7, P = 0.048) were associated with development of severe hepatic toxicity. Increased pre-treatment aspartate aminotransferase(AST; OR = 7.4, P = 0.025) and decreased pre-treatment hemoglobin(OR = 12.5, P = 0.025) were associated with severe albumin toxicity. Increasing pre-treatment model for end-stage liver disease(MELD) score(OR = 1.8, P = 0.033) was associated with severe total bilirubin toxicity. Colorectal adenocarcinoma histology was associated with severe alkaline phosphatase toxicity(OR = 5.4, P = 0.043).CONCLUSION: Clinicians should carefully consider pre-treatment albumin, INR, AST, hemoglobin, MELD, and colorectal histology when choosing appropriate candidates for ^(90) Y microsphere therapy.展开更多

Recurrence is associated with a mortality rate exceeding 75%. Approximately one-third of recurrences develop in the transplanted liver and are therefore amenable to local therapy. A variety of treatment modalities have been reported including resection, transarterial chemo- embolization (TACE), radiofrequency ablation (RFA), ethanol ablation, cryoablation, and external beam irradiation. Goals of treatment are tumor control and the minimization of toxic effect to functional parenchyma. Efficacy of treatment is mitigated by the need for ongoing immunosuppression. Yttrium-90 microspheres have been used as a treatment modality both for primary HCC and for pre-transplant management of HCC with promising results. Twenty-two months after liver transplantation for hepatitis C cirrhosis complicated by HCC, a 42-year old man developed recurrence of HCC in his transplant allograft. Treatment of multiple right lobe lesions with anatomic resection and adjuvant chemotherapy was unsuccessful. Multifocal recurrence in the remaining liver allograft was treated with hepatic intra-arterial infusion of yttrium-90 microspheres (SIR-Spheres, Sirtex Medica Inc., Lake Forest, IL, USA). Efficacy was demonstrated by tumor necrosis on imaging and a decrease in alpha-fetoprotein (AFP) level. There were no adverse consequences of initial treatment.展开更多

Methods Seventeen patients with liver cancer were treated with glass mi crospheres from August 1996 to May 1998. Hepatic radioembolization with 90 Y and lipiodol ultrafluid was used. Percutaneous port catheter system (PCS) implantations via femoral artery were performed in 12 patients.Results In the 17 patients,their mean ratio of absorbed doses b etween tumor and normal liver was 2.4∶1. CT showed a significant reduction in t umor size in 11 of the 17 patients. Average survival was 19.5 months. The indwel ling catheters of all the 12 patients were patent and no catheter tip dlocatio ns were found.Conclusions 90 Y glass microsphere is one of the best radioi sotop es. Not only good responses to the therapy of 90 Y glass microspheres can be achieved in patients with metastatic liver cancer, but also in those with pri mary liver cancer, specially the localized or hypervascular mass. The patients w ith massive arterioportal shunt should not be limited to this form of radiation therapy. The percutaneous PCS implantation via the femoral artery is a new passa geway for the treatment of primary liver cancer with 90 Y glass microspher es and other interventional therapy.展开更多
