Methods： A total of 121 cases of PHC by TACE after 1-2 months of surgery was retrospectively analyzed, followed up and analyzed the free survival time and the factors related to tumor-free survival. Results： In all 121 cases, 1-, 2-, and 3-year tumor-free survival rates were 72.73%, 46.21% and 26.93%, respectively. Gender, age, HBV infection, tumor size, capsule is complete, degree of differentiation and the presence of vascular thrombosis were put into the COX proportional hazards model of survival time to select the influential variables. In the clinical data of all variables entering COX proportional hazards model, tumor size, tumor differentiation and the presence of vascular thrombosis were statistically significant contributions to the model. In the tumor diameter less than or equal 10 cm [P = 0.040, Exp （B） = 2.210], vascular thrombosis [P = 0.039, Exp （B） = 2.922] and the lower degree of tumor differentiation [P = 0.035, Exp （B） = 3.038], the risk of tumor recent recurrence increased. Conclusion： Tumor size, differentiation, and the presence of vascular thrombosis are the independent risk factors affecting the prognosis of PHC after TACE.展开更多

Between January 1994 and January 2007, 107 patients with pathologically confirmed small-sized （E1 cm）, node negative breast cancer who did not receive neoadjuvant or adjuvant chemotherapy were included. The 5-year recurrence-free survival （RFS） was estimated according to different prognostic variables. With a median time of 60 months （range, 8-60 months） follow-up, local and distant recurrence were observed in 25 cases （23.4%）. By univariate analysis, HER-2 positivity, triple negative （TN）, and high Ki-67 index （~14%） were risk factors of a lower RFS （hazard ratio （HR） 6.680, 95% confidence interval （CI） 2.350-18.985, P〈0.0001 for HER-2 positive; HR 4.769, 95%CI 1.559-14.591, P=0.006 for TN; HR 6.030, 95%CI 2.659-13.674, P〈0.0001 for high Ki-67 index）. Patients with grade 3 tumors had a lower RFS （HR 2.922, 95%CI 1.096-7.791, P=0.032） compared with those with grade 1 or grade 2 tumors. By multivariate analysis, HER-2 positivity （HR 10.204, 95%CI 3.391-30.704, P〈0.0001）, TN （HR 10.521, 95% CI 3.152-35.113, P〈0.0001） and high Ki-67 index （HR 10.820, 95%CI 4.338-27.002, P〈0.0001） remained risk factors of RFS. In this cohort, HER-2 positivity, triple neg- ative and high Ki-67 index were independent risk factors of RFS in young patients with Tla,bN0 breast cancer. Subsequent pregnancy did not affect RFS.展开更多
