Objective To explore the therapeutic effect of dual perfusion embolization and chemotherapy via hepatic artery and portal vein(combmation treatment) in the treatment of unresectable PHC.Methods Eighty-one cases of unresectable PHC were randomly divided into two gronps: (1) Combination treatment group.Forty-one cases,These cases received embolization and chemotherapy via hepatic artery and portal vein through a drug delivery system intraoperatively,and then embolization and chemotherapy via the drug pump were given periodically. (2) TACE group.Forty cases.These cases were treated with Seldinger's technique, the dosage of drugs were the same as used in the former group during laparotomy. After 3 times of treatment, AFP, the size of tumor, liver function, body weight, abdominal perimeter, survival time of the two groups were compared.Results The weight, AFP, decrease of tumour size in combination group were much better than those in TACE group( P 0.05). The median survival time in the two groups were 18.0 months and 11.1 months ( P =0.0001). The accumulating survival rate of 6, 9, 12, 24 months were 87.8%, 78.0% , 68.2%,31.7% in combination group, and 70.0%, 52.5%, 30.0%, 5.0% in TACE group, respectively . The factors affecting survival were therapeutic method, liver function, size of tumour.Conclusions Combination treatment is simple, convenient with less complications, and the effect is better than TACE. So it is an effective method for the unresectable hepatic carcinoma.

Objective To evaluate the clinical value of 18 F-FDG PET/CT for restaging, guiding therapeutic strategy and predicting prognosis in patients with postoperative colorectal cancer (PCC). Methods Records of 91 patients (51 males, 40 females;average age (54.90±11.47) years) in whom PCC were eval-uated by 18 F-FDG PET/CT imaging from May 2010 to June 2014 were retrospectively reviewed. All patients underwent evaluation at the First Affiliated Hospital of Soochow University. 18 F-FDG PET/CT results were compared with the results from pathological examination, clinical long-term follow-up (≥6 months ) and conventional imaging. Diagnostic efficiency of 18 F-FDG PET/CT in detecting recurrence and metastases of PCC were calculated. The clinical value of 18 F-FDG PET/CT in restaging and guiding therapeutic strategy were analyzed in patients with true positive results. Kaplan-Meier survival analysis was conducted based on the results of PET/CT and the alteration of therapeutic strategy after PET/CT. Results The sensitivity, specific-ity, accuracy, positive predictive value and negative predictive value of 18 F-FDG PET/CT were 96. 36%(53/55), 83.33%(30/36), 91.21%(83/91), 89.83%(53/59) and 93.75%(30/32), respectively. The median survival time and the 5-year survival rate were 10.00 years and 84% in patients with true negative PET/CT results, and were 6. 33 years and 53% in true positive group. Patients with true negative results showed longer OS and PFS than those with true positive results (χ2=7.753, 8. 933, both P<0.01). Among the 53 patients with true positive PET/CT results, tumor restaging was up-regulated in 32 patients and down-regulated in 2 patients. Therapeutic strategies were changed in 33 patients, in whom the PFS was lon- ger than those without treatment alteration (χ2=4.905, P<0.05) . Conclusion 18 F-FDG PET/CT imaging has the high sensitivity and accuracy in detecting recurrence and metastasis of PCC, with the potential for altering clinical restaging and therapeutic strategy timely.
