Prognosis Nomogram for Hepatocellular Carcinoma Patients with Portal Vein Invasion Undergoing Transarterial Chemoembolization Plus Sorafenib Treatment: A Retrospective Multicentre Study.

OBJECTIVES: To explore the outcomes of combined transarterial chemoembolization (TACE) with sorafenib in hepatocellular carcinoma (HCC) patients with portal vein tumour thrombus (PVTT) and to establish a prognostic prediction nomogram to differentiate target patients and stratify risk. MATERIALS AND METHODS: This multicentre, retrospective study consisted of 185 consecutive treatment-naïve patients with HCC and PVTT treated with TACE plus sorafenib from three institutions between January 1st, 2012 and December 31st, 2017. The primary outcome measurement of the study was overall survival (OS). The type of PVTT was classified by the Liver Cancer Study Group of Japan. The prognostic nomogram was established based on the predictors and was performed with interval validation. RESULTS: The median OS of the Vp1-3 and Vp4 groups was 12.4 months (11.7-18.9) and 8.5 months (7.6-11.2) (P = 0.00098), respectively, and there was a significant difference in the median OS between the Vp1-2 and Vp3 subgroups (16.4 months (12.2-27.9) vs. 10.9 months (8.4-18.1), P = 0.041). The multivariate Cox regression analysis suggested that tumour size, albumin-bilirubin grade, and PVTT type were independent prognostic factors. The C-index value of the nomogram based on these predictors in the entire cohort was 0.731 (0.628-0.833). CONCLUSIONS: After the combined therapy of TACE and sorafenib, advanced HCC patients with segmental or subsegmental PVTT showed better survival than those with main PVTT. The nomogram can be applied to identify advanced HCC patients with PVTT who may benefit most from the combination treatment and be helpful for making decision in clinical practice.

The Taiji and Eight Trigrams chemistry philosophy of chiral iridium(iii) complexes with triplex stereogenic centers.

Four novel chiral iridium(iii) complexes with triplex stereogenic centers were synthesized by introducing chiral carbon atoms into cyclometalated and ancillary ligands, and separated into eight isomers, which coincide with the old Chinese philosophy Eight Trigrams. The electron circular dichroism and circularly polarized luminescence spectra of four pairs of isomers show perfect mirror images with a dissymmetry factor (glum factor) of around 0.003.

Combined endovascular brachytherapy, sorafenib, and transarterial chemobolization therapy for hepatocellular carcinoma patients with portal vein tumor thrombus.

AIM: To evaluate the safety and efficacy of combined endovascular brachytherapy (EVBT), transarterial chemoembolization (TACE), and sorafenib to treat hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus (MPVTT). METHODS: This single-center retrospective study involved 68 patients with unresectable HCC or those who were unfit for liver transplantation and percutaneous frequency ablation according to the BCLC classification. All patients had Child-Pugh classification grade A or B, Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and MPVTT. The patients received either EVBT with stent placement, TACE, and sorafenib (group A, n = 37), or TACE with sorafenib (group B, n = 31). The time to progression (TTP) and overall survival (OS) were evaluated by propensity score analysis. RESULTS: In the entire cohort, the 6-, 12-, and 24-mo survival rates were 88.9%, 54.3%, and 14.1% in group A, and 45.8%, 0%, and 0% in group B, respectively (P < 0.001). The median TTP and OS were significantly longer in group A than group B (TTP: 9.0 mo vs 3.4 mo, P < 0.001; OS: 12.3 mo vs 5.2 mo, P < 0.001). In the propensity score-matched cohort, the median OS was longer in group A than in group B (10.3 mo vs 6.0 mo, P < 0.001). Similarly, the median TTP was longer in group A than in group B (9.0 mo vs 3.4 mo, P < 0.001). Multivariate Cox analysis revealed that the EVBT combined with stent placement, TACE, and sorafenib strategy was an independent predictor of favorable OS (HR = 0.18, P < 0.001). CONCLUSION: EVBT combined with stent placement, TACE, and sorafenib might be a safe and effective palliative treatment option for MPVTT.

[Features of blood supply and results of transarterial infusion and embolization in spinal metastases].

OBJECTIVE: To study the features of blood supply and results of transarterial infusion and embolization in spinal metastases. METHODS: Forty-one patients with spinal metastasis received transarterial infusion and embolization between March 2001 and June 2008. The inclusion criteria were: The metastatic lesion caused back pain; The metastatic lesion involved vertebra at or below T3 level. There were 29 males and 12 females with a mean age of 56.0 (33 - 71) years. Epirubicin was used as the chemotherapeutic agent. Lipoid Ultra-Fluid, Contour SE or gelfoam particles were used as embolitic material. RESULTS: The technical success of therapy was achieved in 52 vertebrae (100%) including 14 thoracic, 35 lumbar and 3 sacral vertebrae. 105 arteries were used for infusion and embolization (16 intercostal arteries, 78 lumbar arteries, 4 iliolumbar arteries, 4 branches of iliac arteries, and 3 median sacral arteries). Lipoid Ultra-Fluid (2 - 8 ml) was used in 15, Contour SE (300 approximately 500 microm, 20 - 100 mg) in 20, and gelfoam particles in 33 arteries. Three days after treatment, complete pain relief (CR) was achieved in 17 patients, partial pain relief (PR) in 20, and moderate pain relief (MR) in 4, with an effective rate of 90.2%. Two weeks after treatment, CR was achieved in 17 patients, PR in 21, and MR in 3, with an effective rate of 92.7%. No adverse nervous system effect occurred. 16 patients developed swelling and pain of normal tissues which were alleviated after symptomatic treatment. CONCLUSION: Transarterial infusion and embolization is an effective therapy in relieving pain resulting from spinal metastases.

[Regulatory effect of bushen jianpi recipe on cellular immunity of patients with primary liver cancer after intervention therapy].

OBJECTIVE: To observe the regulatory effect of Bushen Jianpi Recipe (BSJPR) on cellular immunity the of primary liver cancer patients of Gan-Shen yin-deficiency and Pi qi-deficiency syndrome type after intervention therapy. METHODS: According to the multi-center randomized controlled principle, 117 patients after transcatheter arterial chemoembolization (TACE) were assigned to two groups, 60 in the treated group and 57 in the control group, who were treated respectively with BSJPR and liver protecting remedy (silymarin and vitamin c) for 12 weeks. Changes in TCM syndrome, quality of life (QOL), immediate effect on tumor size and survival time were observed. Meantime, the cellular immune function was also observed, including the T lymphocyte response determined by 3H-TdR, expression of MHC class I/II and B7 molecule detected by FACS, and interleukin 10 and 12 (IL-10, IL-12), interferon-gamma (IFN-gamma) tested by ELISA. RESULTS: In the treated group after treatment, the efficacy for improving TCM syndrome reached 73.33% (44/60 cases), their half-year survival rate being 83.33% (50/60 cases); while those in the control group were 52.63% (30/57 cases) and 70.18% (40/57 cases) respectively, significant difference was shown between the two groups (P <0.05). The patients' QOL was improved in the treated group after treatment, with no obvious adverse reaction. However, the clinical benefit rate in the control group (92.7%, 51/55 cases) was higher than that in the treated group (78.0%, 46/59 cases, P =0. 035). Laboratory examination showed increases of MHC class II (CD14+/HLA-DR) expression on monocyte surface as well as IFN-gamma and IL-12 production in the treated group. CONCLUSION: Using BSJPR together with TACE could enhance patients' cellular immune function to elevate the clinical curative effect on primary liver cancer.

[Survival of patients with liver metastasis from colorectal cancer by different modes of therapy: a report of 363 cases].

OBJECTIVE: To evaluate the correlation between different therapies and survival of liver metastasis from colorectal cancer ( LMCC) , and to compare the clinical outcome of synchronous liver metastasis (SLM) with that of metachronous liver metastasis (MLM). METHODS: The clinical data of 363 patients with LMCC were retrospectively reviewed with focus on the correlation between different therapy and survival. RESULTS: Of these 363 patients, 160 had SLM and 203 had MLM. Between the SLM and MLM group, there was no significant difference in age, or gender or primary cancer site (P > 0. 05 ), but significant differences were observed in condition of liver metastasis including liver lobe involved, focus number, maximum focus diameters and level of serum CEA and CA199 before therapy(P <0. 05). Ninety-one patients underwent curative hepatic resection, 22 of them in the SLM group and 69 in the MLM group. Mortality rate related to operation was 4. 5% (1/22) in SLM group and 2. 9% (2/69) in MLM group( P < 0.05). All patients were followed until 31/6/2005. The 3-year survival rate was 5. 2% with a median survival time of 10 +/- 1 months for the SLM group, and it wasl6. 4% and 17 +/- 1 months for the MLM group (P<0.01). Regarding to the treatment modalities, the 3-year survival rate was 30. 2% with a median survival time of 26 months for curative hepatic resection group, and it was 0% - 16. 7% and 10 - 17 months for non-operation groups treated by intervention, chemotherapy, radiofrequency therapy, percutaneous ethanol injection and Chinese traditional drugs (P <0. 05, P <0. 01 ). CONCLUSION: Curative hepatic resection is still the first choice for liver metastasis from colorectal cancer improving the survival significantly. Other non-operative methods also can improve phase II resection rate. Metachronous liver metastasis has higher resection rate and better survival than the synchronous liver one.

[Epirubicin in the treatment of malignant obstructive jaundice].

OBJECTIVE: To evaluate the safety and efficiency of epirubicin in the treatment of malignant obstructive jaundice (MOJ). METHODS: Thirty-nine patients with diagnosis of MOJ, whose serum total bilirubin (TB) had not dropped to normal level after stent placement or percutaneous transhepatic biliary drainage, received trans-arterial chemoembolization (TACE). During TACE, epirubicin emulsion containing pharmorubicin at dose of 30 mg/m(2) was used. The toxicity and hepatic injury was observed according to WHO anticancer drug toxicity criterion and Child-Pugh classification criterion, respectively. The time of jaundice recurrence and survival were also observed during follow-up. RESULTS: Median total serum bilirubin in 39 patients was 72.7 micromol/L (range: 52.1 - 91.4 micromol/L) before TACE. The dose of pharmorubicin was 40 - 60 mg with a median of 55.0 mg and the amount of lipiodol was 2 - 25 ml. Decrease in white blood cell count was observed: grade I in 41.0% of patients, grade II in 35.9% and grade III - IV in 15.4%. Grade III - IV nausea and vomiting developed in 100% of the patients. Hepatic injury became aggravated in 8 from A to B class patients, in one from A to C class, and in 3 from B to C class according to Child-Pugh classification criterion. No cardiac toxicity was observed in this series. The median survival time was 6.0 months with a range of 2 to 72 months. Jaundice recurred in 19 patients (48.7%) with a medium jaundice recurrence time of 9.0 months (range: 2 - 20 months). CONCLUSION: Epirubicin-lipiodol emulsion at a dose of 30 mg/m(2) is safe and efficient in the management of patients with malignant obstructive jaundice with total serum bilirubin between 51 and 100 micromol/L after biliary drainage.

[A comparative study of MRI manifestations and pathological changes in hepatocellular carcinoma treated by transcatheter arterial chemoembolization with lipiodol].

OBJECTIVES: To analyze the MRI manifestations and pathological changes of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE) with lipiodol. METHODS: 23 patients with 31 HCC lesions treated by TACE underwent MRI examination within 1 week before their surgical resections. MRI was performed with SE sequence (T1WI and FSE T2WI) and FMPSPGR sequence dynamic multi-phase contrast scans. All resected specimens were cut into 5-10mm thick slices, corresponding to the same plane as that of MRI scans. The specimens were wholly embedded in paraffin, serial sections made and stained with hematoxylin and eosin. The MRI findings were thus compared with the pathology of the specimen sections. RESULTS: (1) MRI findings: In all 31 lesions, the signal intensity of lesions varied and was mostly heterogeneous on SE T1WI and T2WI images. Three lesions were inhomogeneous hyper-intensity and the other 28 lesions were iso- or hypo-intensity on FMPSPGR plain scannings. Twenty-two lesions were enhanced on early-phase dynamic scanning, and no enhancement was found in the other 9 lesions. Partial enhancement was also seen in 6 lesions on delay-phase dynamic scanning. (2) Pathologically, no coagulation necrosis was found in 2 specimens, but 6 lesions showed complete coagulation necrosis and 23 showed various degrees of it. The other pathological changes found included intra-tumoral hemorrhage (n=10), intra-lesional fibrotic septa formation (n=5), capsule-like fibrotic tissue proliferation around the lesions (n=12), inflammatory infiltration (n=28), focal mucoid degeneration (n=2), focal hyaline degeneration (n=2), and lipiodol retention (n=6). (3) Radiological-pathological correlation study: hyper-intense areas on T1WI corresponded to areas of coagulation necrosis with or without hemorrhage and of residual viable tumor; iso- and hypo-intense corresponded to areas of coagulation necrosis or residual viable tumor. Hyper-intense areas on T2WI corresponded to those of residual viable tumor or coagulation necrosis with hemorrhage, and iso-intense areas corresponded to those of coagulation necrosis, small residual viable tumor or intra-lesional fibrotic septa formation, and hypo-intense areas corresponded to those of coagulation necrosis or intra-lesional fibrotic septa formation. Areas of enhancement within the lesions on the early-phase dynamic-contrast images corresponded to areas of residual viable tumors, while areas of no enhancement were those of coagulation necrosis, hemorrhage, intra-lesional fibrotic septa formation or small residual viable tumors. Areas of enhancement on the delay-phase dynamic scanning were those of residual viable tumors or intra-lesional fibrotic septa formation, while no enhancement corresponded to the areas of residual viable tumors, coagulation necrosis, and hemorrhage. Areas of enhancement on the delay-phase dynamic scanning corresponded to those areas of fibrosis tissue or residual viable tumors. Inflammatory infiltration was found in areas of different signal intensity on MRI images. CONCLUSIONS: (1) Different pathological changes in HCCs after TACE are represented by various signal intensities on SE sequence images. The only area of hypo-intensity on T2WI has a specificity in representing coagulation necrosis. (2) FMPSPGR sequence dynamic MRI is superior to SE sequence in demonstrating and determining the necrosis and residual viable tumor. Enhanced areas within the lesions on the early-phase dynamic-contrast images represent residual viable tumors and the enhancement of capsule on early-phase dynamic-contrast images also represent subcapsular residual viable tumors. (3) MRI can demonstrate accurately the areas of necrosis and residual viable HCC tissues after TACE and evaluate the effect of TACE.
