ABSTRACT
Objective:To compare the preliminary clinical efficacy of iodized oil embolization and improved microspheres injection embolization in patients with hepatic metastasis from gastrointestinal tumors.Methods:In total 100 patients with hepatic metastasis from gastrointestinal tumors were perspective enrolled from July 2015 to July 2017 in the First Affiliated Hospital of Henan University of Science and Technology. The patients were randomly divided into iodized oil group (45 cases) and microspheres group (55 cases) using random number table. The patients in iodized oil group were firstly received regular perfusion chemotherapy, then underwent the embolization with Iodized oil and epirubicin emulsifier. As for the microspheres group, the patients were received epirubicin and microspheres perfusion and embolization alternately after the same regular perfusion chemotherapy. The post-operation complications were observed. The effective rate of tumor controling at each time point was compared between two groups using χ 2 test. Kaplan-Meier method was used to perform the survival analysis. Log-rank test was used to compare the survival rate between two groups. Results:The operation was successfully performed in all the patients, without severe complications found. The follow up time was 18.7±3.4 months. The tumor control rates of 1, 3, 6, 12 and 24 months after operation in the iodine oil group were 71.1% (32/45), 68.9% (31/45), 51.1% (23/45), 28.9% (13/45), 6.7% (3/45) respectively; while in microspheres group were 90.9% (50/55), 89.1% (49/55), 72.7% (40/55), 49.1% (27/55), 23.6% (13/55), respectively. The tumor control rate in microspheres group was superior to that in iodine oil group ( P<0.05). The median lifetime was 12 months and 17 months for iodine oil group and microspheres group respectively, with significant difference (χ2=8.238, P=0.004) found between two groups. As for the microspheres group, the liver abscess was found in one week after operation in 4 patients, who were cured after drainage and anti-inflammatory treatment. Conclusion:The improved microspheres injection embolization is an effective method for the hepatic metastasis from gastrointestinal tumors and superior to iodized oil embolization in tumor controlling, which may prolong the median survival time.
ABSTRACT
Objective: To observe the value of TACE combined with little dose Apatinib in treatment of hepatcellular carcinoma (HCC) with portal vein thrombi. Methods: Totally 90 unrectable HCC patients with portal vein thrombi were randomly divided into treatment group and control group. Patients in treatment groups (n=38) were started oral little Apatinib 250 mg/d from 3 days after TACE. Patients in control group (n=52) were only underwent TACE. Postoperaion follow up was performed. The level of alpha fetal protein (AFP), survival time difference and response efficacy rate between 2 groups were compared. The postoperation untoward effects were also analyzed between 2 groups. Results: The operation sucess rates were both 100% in both groups. The AFP level of preoperation between 2 groups had no significant difference (t=20.15, P=0.08). The levels of AFP in treatment group postoperation 1 month, 3 months, 6 months, 12 months and 24 months were obviously decreased than those in control group (all P<0.05). The response efficacy rates in treatment group postoperation 1 month, 3 months, 6 months, 12 months and 24 months were 89.47%(34/38), 84.21%(32/38), 78.95%(30/38), 34.21%(13/38) and 10.53%(4/38), respectively; while those in control group were 75.00%(39/52), 67.31%(35/52), 25.00%(13/52), 3.85%(2/52) and 19.23%(10/52), respectively. The mean life time in treatment group was longer than that in control group ([17.12±1.55] months vs [14.21±2.13] months, P=0.01). Although the occurrence rates of hand-foot syndrome, erythra, diarrhoea, abdominal pain, gastrointestinal bleeding, proteinuria, haematuria, high creatinine and urea nitrogen, vertigo, headache, hypertention, erythropenia, leukopenia, low haemoglobin, low platelet, high transaminase, high bilrubin in treatment group were obviously more than control group (all P<0.01), most of them were lower than 3 grade according to the evaluation stantard of National Cancer Institute (NCI). Conclusion: TACE combined with little dose Apatinib are superior to single TACE in treatment of HCC with portal vein thrombi which can effectively prolong median lifetime.
ABSTRACT
Objective To evaluate the efficacy and safety of 125I seed implantation combined with transcatheter arterial chemoembolization (TACE) in the treatment of primary hepatocellular carcinoma (PHC).Methods 156 patients who had unresectable PHC seen from January 2012 to December 2015 in our unit were randomly assigned into the study group (76 patients) and the control group (80 patients).The study group of patients were treated with intra-hepatic implantation of 125I seed + TACE,and the control group of patients were treated with three dimensional conformal radiotherapy (3DCRT) + TACE.After ra diotherapy the two groups of patients underwent 2 to 3 times TACE treatment.The biomarker levels were compared between the two groups before and after treatment,and the short-term efficacy,clinical safety and 1 year survival rates were assessed.Results The success rates of the treatment for the two groups were both 100％.Patients in the study group were implanted with 1 016 125I seeds,with an average of (13.7 ± 2.5) seeds per patient.The two groups had no significant difference on short-term efficacy (P ＞ 0.05).The DCR,ORR and 1 year survival rates in the study group were 63.2％,92.1％,55.5％,and they were 61.3％,90.0％,58.1％ in the control group,respectively.There were no significant differences between these 2 groups (P ＞ 0.05).At 1 month after treatment,the two groups had no significant differences onAFP,IGF-Ⅱ and IGFBP-2 [(5.08±0.85) μg/L vs.(5.12 ±0.79) μg/L,(4.77 ±0.58) μg/L vs.(4.86 ±0.53) μg/L,(4.98 ±0.67) μg/L vs.(5.04 ±0.71) μg/L] (P＞0.05).There were no signif-icant differences on chemotherapy drug toxicities between the two groups (P ＞ 0.05).The incidence of radi-ation hepatitis in the study group was 1.3％,while the incidences of radiation dermatitis,hepatitis,gastriculcer in the control group were 5.0％,8.8％,2.5％,respectively.The radiation dermatitis incidence inthe study group was significantly lower than that of the control group (P ＜ 0.05).In the study group,2 pa-tients (2.6％) had their 125I seed slightly moved.Conclusion The short-term efficacy of 125I seed implan-tation plus TACE in the treatment of PHC is no less than the 3DCRT + TACE regimen,but with less radia-tion side effects.
ABSTRACT
Objective To discuss the clinical value of percutaneous vertebroplasty (PVP) in treating severe vertebral compression fracture. Methods During the period from June 2012 to March 2013, PVP was carried out in 30 patients with severe vertebral compression fracture (30 diseased vertebrae in total). The clinical data were respectively analyzed. According to the shape of compressed vertebra , the fractures were divided into three types: wedge-shaped, double concave and oblong-shaped. For wedge-shaped fracture, PVP was performed via the pedicle access of the healthy side. For double concave type , unilateral pedicle access was used, while for oblong-shaped type unilateral or bilateral access was adopted to conduct PVP according to the distribution of the injected PMMA. The therapeutic results were evaluated by using VAS and pain degree classification standard of WHO. The preoperative and postoperative vertebral height was estimated on the lateral projection. All patients were followed up for six months at out-patient clinic or by telephone. Results The success rate of puncturing was 100%. The preoperative mean VAS was 6.9 ± 0.9. The postoperative VAS at one day, one, 3 and 6 months after the procedure was 5.0 ± 0.9, 3.5 ± 0.7, 2.5 ± 0.8 and 1.6 ± 0.7 respectively. Based on WHO pain degree classification standard, complete remission (CR) was obtained in 25 cases, partial remission (PR) in 3 cases, and invalid in 2 cases. The effective rate (CR +PR) was 93.33%. The mean preoperative height of the compressed vertebrae was (5.77 ± 1.09) mm and the mean postoperative height of the compressed vertebrae was (14.33 ± 2.03) mm. Conclusion For the treatment of severe vertebral compression fractures, percutaneous vertebroplasty is clinically feasible with reliable short-term effect.
ABSTRACT
Objective To discuss the feasibility and short-term clinical effectiveness of DSA-guided percutaneous vertebroplasty (PVP) for the treatment of painful osteoblastic metastatic spinal lesions. Methods During the period from Jan. 2010 to Dec. 2011 at authors’ hospital PVP was carried out in 23 patients with osteoblastic spinal metastases (34 lesions in total). Coexisting osteoblastic pathological fracture was found in twelve patients. The WHO standards, visual analogue scale (VAS) and karnofsky-KPS score were used to evaluate the therapeutic results. Results Technical success was achieved in all patients. All patients were followed up for at least 3 months. Of 20 patients who had complete clinical data, complete remission (CR) was obtained in 6, partial remission (PR) in 10, mild remission (MR) in 3 and no remission (NR) in one. The clinical effectiveness (CR+PR) was 80%. The mean VAS scores dropped from preoperative (7.0 ± 1.6) to (2.2 ± 1.9) at 24 hours after the treatment, and to (2.4 ± 2.1) and (2.5 ± 2.1) at one and three months after the treatment respectively. The mean KPS scores rose from preoperative (76.5 ± 10.4) to (86.5 ± 11.8), (88.0 ± 12.0) and (89.0 ± 10.8) at 24 hours and one, three months after the treatment respectively. Small amount leakage of PMMA was observed in 4 cases (17.4%) with no obvious clinical symptoms. Conclusion DSA-guided PVP is a feasible and effective treatment for painful osteoblastic spinal metastases. This therapy can immediately relieve pain and reinforce spine, besides, it can remarkably improve the living quality and decrease the incidence of paraplegia.
