Transarterial Chemoembolization Combined with Tyrosine Kinase Inhibitors Plus Immune Checkpoint Inhibitors Versus Tyrosine Kinase Inhibitors Plus Immune Checkpoint Inhibitors in Unresectable Hepatocellular Carcinoma with First- or Lower-Order Portal Vein Tumor Thrombosis.

PURPOSE: To compare the efficacy of transarterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) plus immune checkpoint inhibitors (ICIs) (TACE-TKI-ICI) versus TKIs plus ICIs (TKI-ICI) for unresectable hepatocellular carcinoma (HCC) with first- or lower-order portal vein tumor thrombosis (PVTT). MATERIALS AND METHODS: A retrospective study was performed in HCC patients with first- or lower-order PVTT receiving TKIs (Lenvatinib or sorafenib) plus ICIs (camrelizumab, sintilimab, or atezolizumab) with or without TACE from four institutions between January 2019 and January 2022. Propensity score-based method was performed to minimize bias by confounding factors. Tumor response, progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated and compared between the two groups. RESULTS: After inverse probability of treatment weighting, two balanced pseudopopulations were created: 106 patients in the TACE-TKI-ICI group and 109 patients in the TKI-ICI group. The objective response rate was higher in the TACE-TKI-ICI group (50.9% vs. 28.4%, P < 0.001). The median PFS and OS were significantly longer in the TACE-TKI-ICI group than in the TKI-ICI group (PFS: 9.1 vs. 5.0 months, P = 0.005; OS: 19.1 vs. 12.7 months, P = 0.002). In Cox regression, TACE-TKI-ICI treatment was an independent predictor of favorable OS. Treatment-related grade 3/4 AEs were comparable between the two groups (22.6% vs. 17.9%, P = 0.437). CONCLUSION: TACE-TKI-ICI therapy contributed to better tumor control, PFS and OS than TKI-ICI therapy in unresectable HCC patients with first- or lower-order PVTT.

Efficacy and Safety of TACE Combined with a Tyrosine Kinase Inhibitor for the Treatment of TACE-Refractory Hepatocellular Carcinoma: A Retrospective Comparative Study.

PURPOSE: Combining angiogenesis inhibitors may enhance therapeutic efficacy synergistically after TACE refractoriness. The purpose of this study was to compare the outcomes of transarterial chemoembolization (TACE) plus a tyrosine kinase inhibitor (TACE-TKI) with TKI only for patients with TACE-refractory hepatocellular carcinoma (HCC). METHODS: From January 2019 to March 2022, 101 HCC patients confirmed with TACE-refractory were retrospectively reviewed in the study. Progression-free survival (PFS), overall survival (OS), tumor response, and adverse events (AEs) were evaluated between groups. RESULTS: Fifty-two patients undergoing TACE-TKI, while 32 patients receiving TKI alone were included. The objective response rate (ORR) was higher in the TACE-TKI group compared with the TKI group (55.8% vs. 25.0%, P = 0.006). The median PFS in the TACE-TKI group was significantly longer than that in the TKI group (7.6 months vs. 4.9 months, P = 0.018). The median OS was non reach to statistical longer than that in the TKI alone group (19.5 months vs. 17.7 months, P = 0.055). Subgroup analysis showed that TACE-TKI treatment resulted in a significantly longer median PFS and OS for Barcelona Clinic Liver Cancer (BCLC) stage B patients (PFS 11.8 months vs. 5.1 months, P = 0.017; OS 30.3 months vs. 19.4 months, P = 0.022). CONCLUSION: For patients with TACE-refractory HCC, TACE-TKI appeared to be superior to TKI monotherapy with regard to tumor control and PFS. Furthermore, for the BCLC stage B subgroup, TACE-TKI therapy was superior to TKI monotherapy in both OS and PFS.

Comparison of Bronchial Artery Embolisation Versus Conservative Treatment for Bronchiectasis-Related Nonmassive Haemoptysis: A Single-Centre Retrospective Study.

OBJECTIVE: To compare the safety and effectiveness between bronchial artery embolisation (BAE) and conservative treatment for bronchiectasis-related nonmassive haemoptysis patients. MATERIALS AND METHODS: From January 2015 to December 2020, consecutive bronchiectasis-related nonmassive haemoptysis patients who underwent either BAE (n = 98) or conservative treatment (n = 118) were included. Treatment-related complications, length of hospital stays, clinical success rate, patient satisfaction, and recurrence-free survival rates were compared between groups. Prognostic factors related to recurrence were also analysed. RESULTS: During a median follow-up time of 44.8 months (range, 2.4-83.6 months), 34 and 66 patients in the BAE and conservative treatment groups suffered relapse. The 1-year, 2-year, 3-year and 5-year haemoptysis-free survival rates in the BAE and conservative treatment groups were 79.2%, 68.1%, 62.8%, and 57.6% and 64.0%, 52.8%, 44.1%, and 37.0%, respectively (P = 0.007). The minor complication rate after BAE was higher than that after conservative treatment (23/98 vs. 12/118, P = 0.008). BAE was associated with shorter hospital stays (5.0 vs. 7.0 days, P = 0.042) and higher patient satisfaction (88.8% vs. 74.6%, P = 0.008) than those for conservative treatment and with comparable clinical success rates (95.9% vs. 91.5%, P = 0.192). Treatment type, haemoptysis duration, and bronchiectasis severity were independently significant predictors of recurrence for these patients. CONCLUSIONS: BAE could be another option for bronchiectasis-related nonmassive haemoptysis patients. In the patients with longer duration and more severe bronchiectasis, BAE still appeared to have better long-term haemoptysis control than conservative therapy.

Safety and Efficacy of the Double Microcatheter Technique for Splenic Artery Aneurysms: A Single-center Retrospective Study.

PURPOSE: We aimed to assess the safety and efficacy of the double microcatheter technique in the treatment of saccular splenic artery aneurysms. METHODS: From November 2013 to October 2020, 56 patients with saccular splenic artery aneurysms underwent endovascular treatment with the double microcatheter technique at our institution. Technical success was defined as embolization of the aneurysmal cavity with no obstruction of the parent artery. Clinical success was defined as no deaths due to splenic artery aneurysms, and no reintervention, recrudescence or organ dysfunction at 1, 6, and 12 months. RESULTS: The technical success rate was 100%. No major complications related to angiography or embolization were observed. Minor complications included fever, pain, and nausea, and 13 patients developed minor complications. At 1 month, the rate of clinical success was 96.4%. At 6 and 12 months, the clinical success rate was 92.9%. There were no aneurysmal recurrences or necessities of reintervention. CONCLUSIONS: Coil embolization with the double microcatheter technique is a safe and effective modality for treating saccular splenic artery aneurysms and offers a reasonable choice for patients who want to retain their original hemodynamics.

Long-Term Efficacy and Recurrence Prediction of Prostatic Artery Embolization for Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.

PURPOSE: To explore the efficacy of prostatic artery embolization (PAE) for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) during long-term follow-up and analyze predictors related to LUTS recurrence. METHODS: This was a single-center retrospective study involving 125 BPH patients with LUTS who underwent PAE from February 2014 to February 2020. The median follow-up was 36 months. Clinical success was defined as reductions in the International Prostate Symptom Score (IPSS) and quality of life (QoL) score and no need for any other treatment for LUTS; otherwise, it was regarded as a clinical failure. Recurrence was defined as a clinical failure that occurred after an initial success. Cumulative clinical success rates, recurrence rates and re-intervention rates were evaluated. Friedman test was performed to compare differences in IPSS, QoL and prostatic volume (PV) among baseline and follow-up times. Predictors for LUTS recurrence were analyzed with the univariate and multivariate Cox regression model. RESULTS: Technical success (bilateral PAE) rate was 92.8% (116/125). Significant differences in IPSS, QoL and PV were observed between baseline and follow-up time points (P < 0.001). The cumulative clinical success rates at 2, 3, 4 and 5 years were 82.4%, 65.5%, 52.4% and 37.4%. The cumulative recurrence rates and re-intervention rates at 1, 2 and 5 years were 6.8%, 12.7%, 60.4% and 5.9%, 10.2%, 50.8%, respectively. Unilateral PAE was an significant predictor of recurrence (P < 0.05). CONCLUSIONS: PAE is an effective treatment option for LUTS. Unilateral PAE is a significant independent predictor of LUTS recurrence.

Comparison of the Efficacy and Safety of Transarterial Chemoembolization with or without Lenvatinib for Unresectable Hepatocellular Carcinoma: A Retrospective Propensity Score-Matched Analysis.

Background: Combination of angiogenesis inhibitor may achieve better therapeutic synergistic efficacy, considering of tumor hypoxia and promoted angiogenesis after transarterial chemoembolization (TACE). This study aimed to compare the safety and efficacy of TACE plus lenvatinib (TACE-lenvatinib) with TACE alone for patients with unresectable hepatocellular carcinoma (HCC). Methods: Between June 2019 and September 2021, a total of 215 patients diagnosed with unresectable HCC were retrospectively reviewed, including 53 patients who received TACE-lenvatinib and 162 patients who received TACE alone. The patient selection bias between the TACE-lenvatinib group and the TACE group was balanced by propensity score matching analysis at a 1:2 ratio. Progression-free survival (PFS), overall survival (OS) and tumor response were evaluated in the two groups. Results: After propensity score matching analysis, 34 patients receiving TACE-lenvatinib and 68 patients receiving TACE alone were enrolled. The median PFS and OS times in the TACE-lenvatinib group were significantly greater than those in the TACE group (PFS: 8.3 months vs 4.6 months, P = 0.008; OS: 27.7 months vs 18.4 months, P = 0.043). The objective response rate (ORR) in the TACE-lenvatinib group was higher than that in the TACE alone group (64.1% vs 36.5%, P = 0.002). Univariate and multivariate analyses revealed that TACE-lenvatinib treatment was an independent favorable prognostic factor for both PFS and OS. Conclusion: For unresectable HCC patients, the TACE-lenvatinib appeared superior to TACE alone regarding tumor control, PFS, and OS. However, considering the limitations of this study, these results should be interpreted as preliminary and warrant further confirmation.

Transarterial chemoembolization combined with lenvatinib versus transarterial chemoembolization combined with sorafenib for unresectable hepatocellular carcinoma: A comparative retrospective study.

AIM: Tyrosine kinase inhibitors target transarterial chemoembolization (TACE)-mediated vascular endothelial growth factor to inhibit tumor revascularization and to slow tumor progression. The present study aimed to compare the clinical outcomes of TACE combined with lenvatinib (TACE-lenvatinib) and TACE combined with sorafenib (TACE-sorafenib) in patients with unresectable hepatocellular carcinoma (HCC). METHODS: The clinical data of patients diagnosed with unresectable HCC who received TACE-lenvatinib or TACE-sorafenib between January 2018 and April 2021 were retrospectively reviewed. The tumor response, progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated and compared between the two groups. RESULTS: A total of 112 patients were enrolled and classified into the TACE-lenvatinib group (n = 53) and the TACE-sorafenib group (n = 59). The objective response rates of patients in the TACE-lenvatinib and TACE-sorafenib groups were 54.7% and 44.1%, respectively (p = 0.260), and the disease control rates (DCRs) were 81.1% and 61.0% (p = 0.020). The median PFS time was significantly longer in the TACE-lenvatinib group than in the TACE-sorafenib group (10.7 vs. 6.0 months; p = 0.002). The median OS time between the TACE-lenvatinib and TACE-sorafenib groups also showed a significant difference (30.5 vs. 20.5 months, p = 0.018). All treatment-related AEs and grade 3/4 AEs were comparable between the two groups (p > 0.05). CONCLUSION: Compared to TACE-sorafenib, TACE-lenvatinib was associated with better DCR, PFS and OS outcomes in patients with unresectable HCC. In subgroups of Barcelona Clinic Liver Cancer B stage or TACE-refractory patients, TACE-lenvatinib also showed a trend of superiority.

Efficacy and Safety of the Combination of Transarterial Chemoembolization with Camrelizumab plus Apatinib for Advanced Hepatocellular Carcinoma: A Retrospective Study of 38 Patients from a Single Center.

Objective: To evaluate the effectiveness and safety of transarterial chemoembolization (TACE) combined with immune checkpoint inhibition (camrelizumab) plus an antiangiogenic agent (apatinib) for advanced hepatocellular carcinoma (HCC). Methods: Between March 2019 and April 2021, the clinical data of 38 patients diagnosed with advanced HCC who initially received TACE combined with camrelizumab plus apatinib were reviewed retrospectively. The objective response rate (ORR) and disease control rate (DCR) according to modified response evaluation criteria in solid tumors, progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated. Results: At 2-3 months after initial therapy, the ORR and DCR was 50.0% (19/38) and 76.3% (29/38), respectively. The median PFS and OS were 7.3 months (range: 1.0-22.6 months) and 13.5 months (range: 2.3-24.3 months), respectively. Treatment-related AEs (grades 3-4) were observed in 25 patients (67.8%). No treatment-related deaths occurred. Conclusion: The combination of TACE with camrelizumab plus apatinib for the treatment of patients with advanced HCC showed promising efficacy and a manageable safety profile.

Safety and Efficacy of Transarterial Chemoembolization and Immune Checkpoint Inhibition with Camrelizumab for Treatment of Unresectable Hepatocellular Carcinoma.

Background: The clinical outcomes of hepatocellular carcinoma (HCC) patients who receive transarterial chemoembolization (TACE) and immunotherapy are not well characterized. The present study evaluates the safety and efficacy of TACE in combination with immune checkpoint inhibitor treatment for unresectable HCC. Methods: A retrospective analysis of 34 HCC patients who received TACE and treatment with the immune checkpoint inhibitor (ICI), Camrelizumab, between July 2019 and May 2021, was performed. This included 21 patients who developed progressive disease and eight who remained stable after several sessions of TACE, along with five patients who were initially diagnosed with advanced HCC. Adverse events (AEs), objective response rate (ORR) according to modified response evaluation criteria in solid tumors, progression-free survival (PFS), and overall survival (OS) were evaluated. Results: The median follow-up from ICI initiation was 10.6 months (range: 2.4-25.0 months). Grade I/II and grade III/IV AEs from ICI treatment occurred in 20 (58.8%) and 2 patients (5.9%), respectively. Two to three months after ICI therapy, the ORR was 35.3% (12/34) and the median PFS and OS was 6.1 months (range: 1.1-19.3 months) and 13.3 months (range: 2.4-25.0 months), respectively. Conclusion: TACE in combination with ICI could be a promising treatment approach for unresectable HCC patients.

Metallic stent placement versus catheter drainage for malignant bilioenteric anastomotic stricture.

PURPOSE: The purpose of the study was to compare self-expandable metallic stent placement with catheter drainage for malignant bilioenteric anastomotic stricture in terms of efficacy and safety. MATERIALS AND METHODS: This study included 54 patients with malignant bilioenteric anastomotic stricture treated from March 2016 to February 2021. Twenty-seven patients underwent insertion of self-expandable metallic stent (Stent group); the remaining twenty-seven patients underwent internal-external catheter drainage (Catheter group). Technical success was defined as successful placement of stent or drainage catheter in the appropriate position; clinical success was defined as a 20% reduction in serum bilirubin within 1 week after the procedure, compared with baseline. Complications, duration to stent/catheter malfunction, and overall survival were evaluated. RESULTS: Technical success was achieved in all patients in both groups. In the Stent group, 21 patients received one stent and the other 6 patients required two stents. Clinical success rates were similar between the groups [Stent group, 92.6% (25/27); Catheter group, 88.9% (24/27)]. There were no major complications. The median duration to stent/catheter malfunction was significantly longer in the Stent group (130 days) than in the Catheter group (82 days; P = 0.010). The median overall survival was also significantly longer in the Stent group (187 days) than in the Catheter group (118 days; P = 0.038). CONCLUSION: Self-expandable metallic stent placement might be better than internal-external catheter drainage for malignant bilioenteric anastomotic stricture in terms of the duration before stent/catheter malfunction and patient survival.

Prostatic Artery Embolization to Achieve Freedom from Catheterization in Patients with Acute Urinary Retention Caused by Benign Prostatic Hyperplasia.

PURPOSE: To determine the ability of prostatic artery embolization (PAE) to achieve freedom from catheterization in patients with acute urinary retention (AUR) caused by benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This retrospective single-center study was performed between June 2014 and March 2019 in patients with lower urinary tract symptoms (LUTS) caused by BPH. PAE was performed in 154 eligible patients, of which 76 suffered from spontaneous AUR and had indwelling catheters placed and kept until the procedure, owing to clinical failure in the removal of the previous intermittent catheter. Each patient was followed for at least 12 months. The first trial without catheter was performed 3 days after PAE. Successful catheter removal within the first 30 days after PAE was considered a clinical success. The rate of patients free from catheterization, LUTS relief, prostate volume, and adverse events was recorded. RESULTS: Clinical success was achieved in 70 (92.1%) patients. The rates of freedom from catheterization were 90.3% (65/72), 83.3% (60/72), and 80.6% (58/72) at 3-, 6-, and 12-months follow-up, respectively. The median elapsed time from PAE to catheter removal was 10 days. However, 18 patients needed further interventions. Symptom scores revealed a continuous improvement in urinary symptoms. The mean prostate volume showed a statistically significant decrease at 3 and 12 months compared with its baseline value. No severe adverse events occurred. CONCLUSIONS: PAE can achieve freedom from catheterization in patients with AUR caused by BPH.

Superselective Vesical Artery Embolization for Intractable Hemorrhagic Cystitis Following Hematopoietic Stem Cell Transplantation: A Single-Center Retrospective Study in 26 Patients.

PURPOSE: To evaluate the safety and efficacy of superselective vesical artery embolization (SVAE) in the treatment of intractable hemorrhagic cystitis (HC) following hematopoietic stem cell transplantation (HSCT). METHODS: From January 2010 to December 2018, 26 patients with hematologic malignancy who underwent SVAE for treatment of intractable HC following HSCT were retrospectively reviewed. SVAE was performed with 300-500 µm gelatin-sponge particles initially. Technical success was defined as achieving bilateral SVAE for all the prominent vesical arteries. Therapeutic efficacy was defined as: Complete response (CR): macroscopic hematuria completely disappeared on more than 2 consecutive days after SVAE; Partial response (PR): macroscopic hematuria reduced after SVAE or briefly disappeared after SVAE but reappeared soon within 2 days; No response: no response to SVAE or hematuria aggravated after SVAE; Recurrence: macroscopic hematuria relapsed on follow-up after achieving an initial CR. Adverse events were also registered. RESULTS: There was a mean follow-up of 11.4 months (range, 0.5-83.7). The mean interval for the onset of HC after HSCT was 39.7 ± 19.0 days, and mean duration of hematuria before embolization was 14.9 ± 15.7 days. SVAE was technically successful in all patients. After embolization, macroscopic hematuria regressed within 48 h for all patients. The mean urine erythrocyte counts dropped from 14,213.2 ± 20,999.0/uL before SVAE to 6072.9 ± 12,720.7/uL on 3d after SVAE (P = 0.002) and 3720.2 ± 8988.9/uL on 7 d after SVAE (P = 0.001), respectively. Hematuria completely disappeared prior to discharge in 23 (88.5%) patients (including 20 with one embolization and 3 with 2 embolizations) and remainder 3 patients had PR. No major procedure-related complications were noted, except for post-embolization syndrome in 8 patients, which resolved with symptomatic treatment. On follow-up monthly, hematuria recurrence was seen in 4/23 patients (17.4%) and was managed conservatively in 2 patients and with repeat embolization in the remainder 2 patients. CONCLUSION: For fragile patients with hematologic malignancy, SVAE is safe and effective to treat HC following HSCT, even though repeat embolization may be required to achieve a sustained complete remission of the hematuria.

Prostatic Artery Embolization for the Treatment of Recurrent Lower Urinary Tract Symptoms following Transurethral Resection of the Prostate.

PURPOSE: To evaluate the safety and efficacy of prostatic artery embolization (PAE) in patients with recurrent lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) who underwent a previous transurethral resection of the prostate (TURP). MATERIALS AND METHODS: This retrospective study analyzed 15 of 19 patients who underwent PAE for recurrent LUTS after TURP between February 2014 and April 2019. The technical and clinical success rates and complications related to the procedure were recorded. International Prostate Symptom Score (IPSS), quality of life (QoL), and prostatic volume (PV) were evaluated at baseline and 3- and 12-mo follow-up. RESULTS: The intervals from TURP to recurrent symptoms and from TURP to PAE were 4.3 y ± 3.2 and 5.6 y ± 3.8, respectively. Technical success was achieved in all patients. The clinical success rate for LUTS relief at 12 mo was 93.3% (14 of 15). IPSS significantly reduced from 22.5 ± 4.1 at baseline to 9.9 ± 4.9 at 12-mo follow-up, and QoL score improved from 4.7 ± 1.0 to 2.1 ± 1.1 (P < .05 for both). There was a significant mean reduction of 26.6% in PV at 12 mo, improving from 100.7 cm3 ± 38.5 to 73.9 cm3 ± 29.4 (P < .05). No severe complications were encountered. CONCLUSIONS: PAE may be a safe and effective treatment option for the management of recurrent LUTS secondary to BPH in patients who have previously undergone TURP.

Skeletal-muscle index predicts survival after percutaneous transhepatic biliary drainage for obstructive jaundice due to perihilar cholangiocarcinoma.

BACKGROUND: Sarcopenia is emerging as a prognostic factor in patients with malignant diseases. The prognostication of perihilar cholangiocarcinoma (PHC) with obstructive jaundice was complex, because these patients suffered compete mortality events beyond cancer itself. Our study was to investigate the association between low skeletal-muscle index and overall survival (OS) after percutaneous transhepatic biliary drainage (PTBD) for obstructive jaundice due to PHC. METHODS: We performed a retrospective survival analysis of patients undergoing PTBD for PHC-related obstructive jaundice between January 2016 and March 2019. Using computed tomography, we measured skeletal-muscle mass at the third lumbar vertebra (L3) to obtain a skeletal-muscle index (SMI). Then, we compared OS between low- and high-SMI groups. Furthermore, factors that could potentially affect OS were assessed. RESULTS: One hundred and four patients (56 males; mean age 66 ± 12 years) were analyzed. Median OS after PTBD was 150 days. OS was shorter in patients with low SMI than in those with high SMI (median OS, 120 vs. 270 days; P < 0.001). Multivariate analysis indicated that low SMI (hazard ratio [HR] 3.46; 95% confidence interval [CI] 1.14-5.60; P < 0.001), intrahepatic metastasis (HR 2.98; 95% CI 1.89-4.69; P < 0.001) and elevated carbohydrate antigen (CA) 19-9 level (HR 1.00; 95% CI 1.00-1.00; P = 0.04) were significantly associated with OS. CONCLUSION: Low SMI was a predictor of dismal OS after PTBD for patients with PHC-related obstructive jaundice.

Emergency transarterial embolization followed by staged hepatectomy versus emergency hepatectomy for ruptured hepatocellular carcinoma: a single-center, propensity score matched analysis.

PURPOSE: To compare the feasibility and efficacy of emergency transarterial embolization (TAE) followed by staged hepatectomy (SH) with emergency hepatectomy (EH) for ruptured hepatocellular carcinoma (HCC). METHODS: Between January 2012 and December 2017, 102 patients with HCC rupture received EH or emergency TAE followed by SH in our center. Patients were followed until April 2019. Propensity score matching (PSM) analysis was used at a 1:2 ratio, resulting in 20 patients in the SH group and 40 patients in the EH group. We retrospectively compared the operative variables, recurrence status, disease-free survival (DFS), and overall survival (OS) of patients between the two matched groups. RESULTS: Compared with the matched EH group, the SH group showed significantly decreased perioperative blood loss or blood transfusion, shortened intraoperative duration of clamping and postoperative hospital stay (P < 0.05), while achieving comparable long-term OS (SH group: 39.0 months vs. EH group: 38.1 months, P = 0.342). There was no significant difference in the peritoneal metastasis rate (SH group: 20.0% vs. EH group: 25.6%, P = 0.874), recurrence rate (SH group: 65.0% vs. EH group: 71.8%, P = 0.333) or DFS (SH group: 9.4 months vs. EH group: 7.7 months, P = 0.602) between the two matched groups. CONCLUSION: For resectable ruptured HCC, emergency TAE of rupture which followed by SH, could bring patients about intraoperative and postoperative benefits when compared to EH. Moreover, this combination treatment will not increase the rate of peritoneal metastasis or recurrence, and might achieve favorable survival benefits for patients.

Angiographic Findings Relevant to Prostatic Artery Embolization in Patients with Prostate Cancer.

The 2014-2018 angiograms of 58 patients with prostate cancer were retrospectively analyzed to illustrate angiographic findings during prostatic artery embolization. Arteriovenous fistulae were observed in 6 patients (6/58, 10.3%), with no difference between patients with or without prior iodine-125 seeds implantation (5/48, 10.4% vs 1/10, 10.0%; P > .05); tumor staining was not detected. The origins of the prostatic arteries included the internal pudendal artery (n = 45, 32.4%), the superior vesical artery (n = 38, 27.3%), the obturator artery (n = 28, 20.1%), the gluteal-pudendal trunk (n = 21, 15.1%), the inferior gluteal artery (n = 3, 2.2%), the accessory pudendal artery (n = 3, 2.2%), and the superior gluteal artery (n = 1, 0.7%).

Treatment strategies and prognosis for initially unresectable ruptured hepatocellular carcinoma: a single-center experience in 94 patients.

PURPOSE: To identify the treatment options and prognostic factors for patients with initially unresectable ruptured hepatocellular carcinoma (HCC). METHODS: Between June 2012 to December 2016, 94 consecutive patients with initially unresectable ruptured HCC were analyzed retrospectively in this study. Patients were followed until December 2017. Predictors of short-term (≤30 days) and long-term (>30 days) survival were identified by using logistic regression model and Cox proportional hazard model, respectively. RESULTS: Of the 94 patients, initial hemostasis treatment was achieved by transarterial embolization (TAE) in 59 patients, surgical hemostasis in 14, and conservative treatment in 21. Twenty-five (26.6%) patients died within 30 d after tumor rupture. In the multivariate analysis, patients treated with aggressive initial treatment strategies (TAE or surgical hemostasis) (P < 0.001) or those with better Child-Pugh class (P = 0.003) and absence of shock on admission (P = 0.001) had a better chance of short-term survival. Of the 69 patients who survived more than 30 days after initial treatment, the median survival time was 268 d. In the multivariate analysis, among the 69 who survived, early modified LCSGJ stage (P = 0.003) and staged hepatectomy as definitive treatment (P < 0.001) were significant predictors of increased long-term survival. CONCLUSION: Short-term survival of patients with initially unresectable ruptured HCC could achieve with better Child-Pugh class, absence of shock and aggressive initial treatment strategies. After survived the emergency phase of tumor rupture, long-term survival was significantly increased with early modified LCSGJ stage and staged hepatectomy therapy.

Efficacy and prognostic factors of transarterial embolization as initial treatment for spontaneously ruptured hepatocellular carcinoma: a single-center retrospective analysis in 57 patients.

PURPOSE: To evaluate the efficacy and prognostic factors following transarterial embolization (TAE) as initial treatment for spontaneously ruptured hepatocellular carcinoma (HCC). METHODS: From June 2012 to June 2016, a total of 57 spontaneously ruptured HCC patients who received TAE as initial therapy were retrospectively studied at our institution. Patients were followed until October 2016. Survival rates were estimated using the Kaplan-Meier method, and prognostic factors related to survival were evaluated using Cox regression analysis. RESULTS: Among them, 8 (14.0%) patients died within 30 days after initial TAE. The median overall survival time was 208 days. The 6-month, 1-year, and 2-year cumulative overall survival rates were 50.3%, 35.9%, and 14.7%, respectively. Multivariate analysis indicated that tumor size [HR (hazard ratio) 1.12; 95% CI (confidence interval) 1.02-1.23, P = 0.022] Child-Pugh class (HR 1.78; 95% CI 1.13-2.80; P = 0.013), absence of shock on admission (HR 0.40; 95% CI 0.17-0.95; P = 0.039), and embolization with lipiodol and gelatin sponge particles (HR 0.33; 95% CI 0.16-0.70; P = 0.004) were independent prognostic factors for survival. CONCLUSION: TAE appeared to be an effective initial treatment for spontaneously ruptured HCC. The results indicated that large tumors, poor Child-Pugh class, and shock on admission were associated with poor prognosis. For these patients, embolization with lipiodol and gelatin sponge particles could achieve better survival than PVA particles used.

Study of Percutaneous Stent Placement with Iodine-125 Seed Strand for Malignant Biliary Obstruction.

PURPOSE: To evaluate the effectiveness and safety of simultaneous placement of a self-expandable metallic stents (SEMS) and iodine-125 seed strand in the management of malignant obstructive jaundice (MOJ). MATERIALS AND METHODS: This study included 132 patients with MOJ treated from November 2015 to October 2017. Forty-five patients underwent insertion of SEMS with iodine-125 seed strands (Seeds group); the remaining 87 patients underwent SEMS placement alone (Control group). Technical success was defined as accurate, successful deployment of SEMS with or without iodine-125 seed strand; clinical success was defined as 20% reduction in serum bilirubin within 1 week after the procedure, compared with baseline. Complications, duration of primary stent patency, and overall survival were evaluated. RESULTS: Technical success was achieved in all patients in both groups. In the Seeds group, an average of 14 seeds (range 8-22) were implanted in the bile duct as a strand. Clinical success rates were similar between the groups (Seeds group, 93.3%; Control group, 95.4%). Major complications occurred in only one patient, in the Control group. The median period of primary stent patency was significantly longer in the Seeds group (194 days) than in the Control group (86 days; P = 0.049). The median overall survival was also significantly longer in the Seeds group (194 days) than in the Control group (96 days; P = 0.031). CONCLUSION: SEMS combined with iodine-125 seed strands is effective and safe in the management of MOJ and can improve stent patency and patient survival.
