ABSTRACT
Hepatic artery infusion chemotherapy (HAIC) has good clinical efficacy in the treatment of advanced hepatocellular carcinoma (HCC); however, its efficacy varies. This review summarized the ability of various markers to predict the efficacy of HAIC and provided a reference for clinical applications. As of October 25, 2023, 51 articles have been retrieved based on keyword predictions and HAIC. Sixteen eligible articles were selected for inclusion in this study. Comprehensive literature analysis found that methods used to predict the efficacy of HAIC include serological testing, gene testing, and imaging testing. The above indicators and their combined forms showed excellent predictive effects in retrospective studies. This review summarized the strategies currently used to predict the efficacy of HAIC in middle and advanced HCC, analyzed each marker's ability to predict HAIC efficacy, and provided a reference for the clinical application of the prediction system.
ABSTRACT
Soil salinization poses a significant global challenge, exerting adverse effects on both agriculture and ecosystems. Planting halophytes has the potential ability to improve saline-alkali land and enhance ecosystem multifunctionality (EMF). However, it remains unclear which halophytes are effective in improving saline-alkali land and what impact they have on the rhizosphere microbial communities and EMF. In this study, we evaluated the Na+ absorption capability of five halophytes (Grubovia dasyphylla, Halogeton glomeratus, Suaeda salsa, Bassia scoparia, and Reaumuria songarica) and assessed their rhizosphere microbial communities and EMF. The results showed that S. salsa possessed the highest shoot (3.13 mmol g-1) and root (0.92 mmol g-1) Na+ content, and its soil Na+ absorption, along with B. scoparia, was significantly higher than that of other plants. The soil pH, salinity, and Na+ content of the halophyte rhizospheres decreased by 6.21%, 23.49%, and 64.29%, respectively, when compared to the bulk soil. Extracellular enzymes in the halophyte rhizosphere soil, including α-glucosidase, ß-glucosidase, ß-1,4-N-acetyl-glucosaminidase, neutral phosphatase, and alkaline phosphatase, increased by 70.1%, 78.4%, 38.5%, 79.1%, and 64.9%, respectively. Furthermore, the halophyte rhizosphere exhibited higher network complexity of bacteria and fungi and EMF than bulk soil. The relative abundance of the dominant phyla Proteobacteria, Firmicutes, and Ascomycota in the halophyte rhizosphere soil increased by 9.4%, 8.3%, and 22.25%, respectively, and showed higher microbial network complexity compared to the bulk soil. Additionally, keystone taxa, including Muricauda, Nocardioides, and Pontibacter, were identified with notable effects on EMF. This study confirmed that euhalophytes are the best choice for saline-alkali land restoration. These findings provided a theoretical basis for the sustainable use of saline-alkali cultivated land.
ABSTRACT
Hepatocellular carcinoma (HCC) is one of the most common malignancies and the third leading cause of cancer-related deaths globally. Hepatic arterial infusion chemotherapy (HAIC) treatment is widely accepted as one of the alternative therapeutic modalities for HCC owing to its local control effect and low systemic toxicity. Nevertheless, although accumulating high-quality evidence has displayed the superior survival advantages of HAIC of oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX) compared with standard first-line treatment in different scenarios, the lack of standardization for HAIC procedure and remained controversy limited the proper and safe performance of HAIC treatment in HCC. Therefore, an expert consensus conference was held on March 2023 in Guangzhou, China to review current practices regarding HAIC treatment in patients with HCC and develop widely accepted statements and recommendations. In this article, the latest evidence of HAIC was systematically summarized and the final 22 expert recommendations were proposed, which incorporate the assessment of candidates for HAIC treatment, procedural technique details, therapeutic outcomes, the HAIC-related complications and corresponding treatments, and therapeutic scheme management.

BACKGROUND: Cavernous transformation of the portal vein (CTPV) due to portal vein obstruction is a rare vascular anomaly defined as the formation of multiple collateral vessels in the hepatic hilum. This study aimed to investigate the imaging features of intrahepatic portal vein in adult patients with CTPV and establish the relationship between the manifestations of intrahepatic portal vein and the progression of CTPV. METHODS: We retrospectively analyzed 14 CTPV patients in Beijing Tsinghua Changgung Hospital. All patients underwent both direct portal venography (DPV) and computed tomography angiography (CTA) to reveal the manifestations of the portal venous system. The vessels measured included the left portal vein (LPV), right portal vein (RPV), main portal vein (MPV) and the portal vein bifurcation (PVB). RESULTS: Nine males and 5 females, with a median age of 40.5 years, were included in the study. No significant difference was found in the diameters of the LPV or RPV measured by DPV and CTA. The visualization in terms of LPV, RPV and PVB measured by DPV was higher than that by CTA. There was a significant association between LPV/RPV and PVB/MPV in term of visibility revealed with DPV (P = 0.01), while this association was not observed with CTA. According to the imaging features of the portal vein measured by DPV, CTPV was classified into three categories to facilitate the diagnosis and treatment. CONCLUSIONS: DPV was more accurate than CTA for revealing the course of the intrahepatic portal vein in patients with CTPV. The classification of CTPV, that originated from the imaging features of the portal vein revealed by DPV, may provide a new perspective for the diagnosis and treatment of CTPV.
ABSTRACT
In order to conduct in-depth research on the mechanisms of cancer diagnosis and treatment, it is very important to develop fluorescent probes to study the interactions between different organelles and understand the relationship between various organelles and cell viability. However, the lack of fluorescent probes to visualize two or more targets has resulted in limited studies of intracellular interactions between different organelles. To this end, in this work, we developed a near-infrared (NIR) AIE probe with dual-color emission, NAP-Py-E, for mitochondria and lipid droplets imaging. The probe NAP-Py-E consists of lipophilic fraction, pyridine cation structure and esterase hydrolysis site. Interestingly, NAP-Py-E first targets mitochondria and emits red fluorescence; after partially hydrolyed by esterase in living cells, the hydrolysate NAP-Py accumulates in lipid droplets and emits green fluorescence. The probe has been successfully used to assess cell viability due to its dual-color emission and dual-organelle targeted changes.

Background: Primary hepatocellular carcinoma is often complicated with hepatitis and liver cirrhosis. Some patients develop different degrees of splenomegaly, hypersplenism and hypohepatia due to the aggravation of liver cirrhosis, which to some extent interfere with the treatment of tumors and even affect the prognosis of patients. In this study, we prospectively evaluate the efficacy and safety of simultaneous CalliSpheres® microspheres transcatheter arterial chemoembolization (CSM-TACE) and partial splenic embolization (PSE) using 8spheres® for hepatocellular carcinoma (HCC) with hypersplenism. Methods: Ninety consecutive HCC patients with hypersplenism who underwent CSM-TACE were selected: 32 patients in CSM-TACE+PSE group, and 58 patients in CSM-TACE group. The peripheral blood cell counts (leukocyte, platelet (PLT), liver function and red blood cell (RBC)), CSM-TACE and/or PSE related complications, and the tumor control rate at 1 month after CSM-TACE were compared. The survival time and prognostic factors were also observed. Results: Before CSM-TACE, there were no significant differences in sex, age, Child-Pugh grade, tumor size, and alpha-fetoprotein (AFP) between the two groups. After CSM-TACE, the PLT and white blood cell (WBC) counts in CSM-TACE+PSE group were significantly higher than those in the CSM-TACE group (P<0.05). There were no significant differences in RBC before and after treatment (P > 0.05). In the CSM-TACE group, there were no significant differences in WBC, PLT, and RBC before and after treatment (P > 0.05). There was no significant difference in liver function at 1 month after treatment between the two groups. The cholinesterase (CHE) level in the CSM-TACE+PSE group after CSM-TACE+PSE was obviously higher than that before CSM-TACE+PSE and higher than that in the CSM-TACE group (P<0.05). However, the level of CHE returned to the preoperative level 1 month after CSM-TACE in the CSM-TACE group. The objective response rate (ORR) and median overall survival (OS) in the CSM-TACE+PSE group were higher than those in the CSM-TACE group (P<0.05). The adverse reactions of the two groups were fever, abdominal pain, stomach discomfort, nausea, and vomiting, and no serious complications occurred. The degree of abdominal pain and fever in the experimental group was lower than that in the control group (P > 0.05). Conclusions: Simultaneous CSM-TACE and PSE using domestic embolization particles for HCC with hypersplenism have good safety and efficacy and has a low incidence of PSE-related adverse events, it is conducive to improving liver function reserve, and can further improve the median OS.
ABSTRACT
Objective: To observe the early changes in peripheral blood cytokine levels after treatment of metastatic hepatic carcinoma (MHC) with CalliSpheres microspheres drug-eluting beads (DEB) transcatheter arterial chemoembolization (CSM-TACE). Methods: Twenty-eight patients with refractory MHC who underwent CSM-TACE were selected prospectively, and 5mL of peripheral blood was collected before CSM-TACE and on the 2nd and 5th day after CSM-TACE. Flow cytometry was used to detect immunological indicators. The early changes in levels of peripheral blood cell inflammatory factors Th1 (interleukin 2 (IL-2), tumor necrosis factor-α (TNF-a), interferon (IFN-r)), Th2 (IL-4, IL-6, IL-10), and Th17 (IL-17A) were observed after CSM-TACE, as well as the ratio of CD4+/CD8+. Results: All the 28 patients underwent CSM-TACE successfully. CT at 4 days after CSM-TACE showed clear outline low-density changes in liver tumors, and honeycomb necrosis was observed in the tumors in some cases. After CSM-TACE, the IL-6 and IL-10 levels were increased and then decreased again. After CSM-TACE, IL-2 showed a trend of transient increase and then decreased again, and the TNF-a level decreased temporarily, and then decreased. After CSM-TACE, the IFN-r level showed a continuous and slowly increasing trend. The IL-17 level showed a continuous downward trend, and the CD4+/CD8+ ratio showed a gradual and continuous upward trend, and there was a negative correlation between them. Conclusions: There are complex dynamic changes in TH1/Th2 in the early stage of CSM-TACE, and the acute inflammatory response and the enhancement of the body's immune anti-tumor response coexist.
ABSTRACT
OBJECTIVE: To explore the clinical efficacy and prognostic factors of the use of Gelfoam for drug-eluting bead (DEB) transarterial chemoembolization (GMD-TACE) in patients with unresectable large hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT). METHODS: A retrospective analysis was conducted using the mRECIST standard to evaluate tumor response after GMD-TACE. Overall survival time, median survival time, time to progression (TTP) after the first intervention, and other treatment methods were recorded. RESULTS: The follow-up time was 2-110 months (mean 17.97 + 19.12 months), the median follow-up time was 12.5 months, and the first TTP after the first GMD-TACE was 4 months (95% CI 3.020-4.980). The median overall survival (OS) time was 14 months (95% CI 9.801-18.199). The 1-, 3-, and 5-year survival rates were 53.6%, 32.3%, and 8.9%, respectively. Multivariate analysis showed that the type of tumor thrombus was an independent factors affecting prognosis, and combination therapy was a protective factor affecting prognosis. CONCLUSIONS: GMD-TACE can be used as the core treatment for unresectable large HCC combined with a PVTT. This can improve the quality of life and further improve the median OS, and is worthy of clinical promotion and application.

ABSTRACT: To assess the clinical efficacy and safety of gelatin sponge microparticles-transcatheter arterial chemoembolization (GSMs-TACE) plus synchronous antigen-presenting dendritic cell (DC) sequential reinfusion for advanced large liver cancer (LC).Patients with large LC were assigned to the experimental (combined sequential DC therapy) or control group. All patients received standardized GSMs-TACE. In the experimental group, 60âmL of peripheral blood was collected for in vitro culture of DCs (10-14âdays). Then, intravenous reinfusion was conducted 3 times within 10, 20, and 30âdays after surgery. Adverse reactions during the treatment were recorded and evaluated. The overall survival, transcatheter arterial chemoembolization frequency, and physical score (PS) were calculated.The median survival time of the experimental group was significantly longer than that of the control group. There were significant differences in median progression-free survival between the 2 groups (Pâ<â.05) and the objective effective rate at 1 and 6âmonths and 1âyear (Pâ<â.05), but not 2âyears (Pâ>â.05). The PSs of 2 groups were significantly improved at 1âmonth after GSMs-TACE, with more obvious improvement in the experimental group (Pâ<â.05).GSMs-TACE plus synchronous DC sequential reinfusion significantly prolonged the median survival time, improved the tumor response rate and PS, prolonged progression-free survival, and reduced intervention frequency. GSMs-TACE plus synchronous DC sequential reinfusion treatment is suitable for comprehensive treatment of patients with advanced larger LC in China.

ABSTRACT: Surgical resection (SR) is recommended as a radical procedure in the treatment of hepatocellular carcinoma (HCC). However, postoperative recurrence negatively affects the long-term efficacy of SR, and preoperative adjuvant therapy has therefore become a research hotspot. Some clinicians adopt transcatheter arterial chemoembolization (TACE) as a preoperative adjuvant therapy in patients undergoing SR to increase the resection rate, reduce tumor recurrence, and improve the prognosis. However, the findings of the most relevant studies remain controversial. Some studies have confirmed that preoperative TACE cannot improve the long-term survival rate of patients with HCC and might even negatively affect the resection rate. Which factors influence the efficacy of preoperative TACE combined with SR is a topic worthy of investigation. In this review, existing clinical studies were analyzed with a particular focus on several topics: screening of the subgroups of patients most likely to benefit from preoperative TACE, exploration of the optimal treatment regimen of preoperative TACE, and determination of the extent of tumor necrosis as the deciding prognostic factor.

OBJECTIVE: To retrospectively analyze the safety and long-term clinical efficacy of gelatin sponge microparticles combined with the chemotherapy drug pirarubicin for hepatic transcatheter arterial chemoembolization (GSMs-TACE) in order to treat breast cancer liver metastasis (BCLM). METHODS: Twenty-seven BCLM patients who underwent GSMs-TACE from July 2010 to July 2016 were enrolled. Tumor target blood vessels were slowly and regionally embolized with absorbable gelatin sponge particles and pirarubicin injections. Plain computed tomography (CT) scans and biochemical indexes were re-examined at 4 days after treatment, and enhanced CT scans or magnetic resonance images and biochemical indexes, 1 month later. For patients with stable tumors, the follow-up period was 2 to 3 months, and the tumor response was evaluated using Modified Response Evaluation Criteria in Solid Tumors. Adverse reactions, survival time, and prognostic factors were assessed. RESULTS: By October 2019, 27 patients with BCLM had undergone GSMs-TACE, with an average of 2.44 ± 1.58 treatments. The 1-, 3-, and 5-year survival rates were 62.96%, 22.22%, and 14.81%, respectively, and the mOS was 22.0 months. No serious complications, such as acute liver failure and liver abscess, had occurred. There were two cases of acute cholecystitis that recovered after symptomatic treatment. Multivariate analysis of the prognosis showed that the primary tumor size, number of metastatic lymph nodes, estrogen receptor/progesterone receptor (ER/PR) status, and time to postoperative liver metastasis and combination therapy were statistically significant. CONCLUSIONS: The overall prognosis of BCLM was poor. GSMs-TACE was safe and effective for BCLM treatment and could prolong the median survival time of patients. Therefore, it is worthy of widespread clinical application.

Objective To explore the feasibility of using ultrasound to evaluate stent placement for managing graft stenosis after Meso-rex bypass for cavernous transformation of the portal vein in adults. Methods This study enrolled the patients who underwent Meso-rex bypass due to cavernous transformation of the portal vein,were diagnosed graft stenosis by postoperative ultrasound,and then underwent percutaneous portal vein puncture portography and stent placement.We then compared the ultrasonic measurement indicators and sonographic manifestations before and after stent placement,and evaluated the alleviation of portal hypertension symptoms after stent placement and related clinical indexes. Results Finally,8 patients were enrolled in this study,including 5 males and 3 females,with an average age of(32.4±14.7)years.The median duration of follow-up was 26 months after stent placement.The mean diameter of graft stenosis was(2.74±0.23)mm after Meso-rex bypass and became wider[(7.23±0.68)mm]after stent placement(P=0.000).The mean maximum velocity at graft stenosis was(195.88±30.83)cm/s after Meso-rex bypass and became lower[(72.75±29.94)cm/s]after stent placement(P=0.000).The color Doppler flow imaging at graft stenosis presented colorful blood flow,and presented regular near laminar flow within the stent and characteristic reverse flow within the left portal vein after stent placement.No gastrointestinal bleeding or ascites occurred after interventional therapy,and the mean thickness of spleen decreased from 6.0 cm before stent placement to 5.4 cm(P=0.018).After stent placement,the platelet count increased from(51.57±18.83)×109/L to(149.00±58.96)×109/L(P=0.002),and the serum ammonia level decreased from(66.25±21.78)µmol/L to(44.88±10.60)µmol/L(P=0.012). Conclusions Ultrasound can accurately assess graft patency before and after stent placement in patients with stenosis after Meso-rex bypass,and effectively monitor the hemodynamic changes in the portal venous system.The clinical symptoms can be relieved after interventional therapy.

BACKGROUND: To observe the medium- and long-term clinical efficacy and safety of radioactive 125I seed implantation for refractory malignant tumours based on CT-guided 3D template-assisted technique. METHODS: Twenty-five patients with refractory malignant tumours who underwent radioactive 125I seed implantation based on CT-guided 3D template-assisted technique were selected. The post-operative adverse reactions were recorded. The number of puncture needles and particles used in the operation, dosimetric parameters, post-operative physical strength scores, and tumour response were statistically analysed. The overall survival time and survival rate were calculated, and the effect and prognosis were assessed. RESULTS: 125I seed implantation was successful in all patients without serious complications. The average number of implanted puncture needles was 17 (19.12 ± 13.00), and the median number of particles was 52 (55.12 ± 32.97). D90 in the post-operative clinical target volume (CTV) (93.24 ± 15.70 Gy) was slightly lower than that in the pre-operative CTV (93.92 ± 17.60 Gy; P > 0.05). The D90 in the post-operative planning target volume (PTV) (142.16 ± 22.25 Gy) was lower than the pre-operative PTV (145.32 ± 23.48 Gy; P > 0.05). The tumour responses at 6 months post-operatively: complete remission (CR), 20% (5/25); partial remission (PR), 48% (12/25); stable disease (SD), 24% (6/25); progressive disease (PD), 8% (2/25); CR + PR, 68% (17/25); and local control rate, 92% (23/25). The 6-, 12-, and 24-month survival rates were 100, 88, and 52%, respectively. The post-operative physical strength score (Karnofsky performance score, KPS) exhibited a gradual trend towards recovery, which rose to the highest value 12 months after implantation and then decreased slightly, but the average score was still > 90 points. There was one intra-operative pneumothorax, and two patients with superficial malignant tumours developed skin ulcerations. Multivariate analysis of prognosis showed that tumour sites and types were independent risk factors affecting survival. The number of needles and particles and template types were not the factors. CONCLUSIONS: 3D template combined with CT-guided radioactive 125I seed implantation can improve the rational distribution of radiation dose in the tumour target area because accurate radioactive 125I particle implantation was achieved. This technique has fewer complications and can further extend the overall survival and improve the quality of life.

Ginsenoside-Rg5, which is derived from high temperature-processed ginseng, exhibits beneficial health effects. In the present study, ginsenoside-Rg5 was directly and rapidly prepared through the extraction of ginseng fibrous root powder (GFRP) at atmospheric pressure. The results showed that the highest extraction yield (3.79%) was obtained under optimal conditions (extraction temperature of 85 °C, acid concentration of 0.06 mol/L, sample to solvent ratio of 1:55 g/mL and ethanol concentration of 95% after 4 h). The current method integrates the extraction of original saponins and the modification of the saponins to rare ginsenosides Rg5, which was more simpler operation, more milder preparation condition and more efficient.
ABSTRACT
BACKGROUND: Renal artery stenosis (RAS) is always associated with abnormalities in renal microvascular perfusion (RMP). However, few imaging methods can simultaneously evaluate the degree of luminal stenosis and RMP. Thus, this study will aim to evaluate the feasibility of using contrast-enhanced ultrasound (CEUS) for assessing both RAS and RMP to achieve a one-stop assessment of patients with suspected renovascular hypertension. METHODS: This will be a single-center diagnostic study with a sample size of 440. Patients with chronic kidney disease (CKD) and suspected of having resistant hypertension will be eligible. Patients with Stages 1-3 CKD will undergo CEUS and computed tomography (CT) angiography (CTA). Values obtained by CEUS and CTA for diagnosing low-grade (lumen reduced by <60%) and high-grade (lumen reduced by ≥60%) RAS will be compared. Moreover, all patients will also undergo radionuclide imaging. The diagnostic value for RAS will be assessed by the receiver operating characteristic curve, including the accuracy, sensitivity, specificity, positive predictive values, negative predictive values, and area under the ROC. Pearson correlation analysis will be performed to assess the association between CEUS findings for RMP and glomerular filtration rate measured by a radionuclide imaging method. CONCLUSION: The data gathered from this study will be used to evaluate the feasibility of expanding clinical applications of CEUS for evaluation of patients with suspected renovascular hypertension.

PURPOSE: We evaluated the clinical efficacy of gelatin sponge microparticle (GSM) -mediated chemoembolization for the treatment of patients with liver metastases following surgery for gastrointestinal tumors. MATERIALS AND METHODS: In a retrospective analysis of 37 patients who were treated at our hospital with GSM-mediated chemoembolization for liver metastases over 13 years, we evaluated outcomes using a modified response evaluation criteria in solid tumors system and also assessed liver function and adverse effects. All patients had previously undergone surgery for gastrointestinal tumors. RESULTS: Treatment produced various degrees of necrosis and shrinkage of lesions among our patients. Two patients achieved a complete response (CR), 27 showed a partial response (PR), five had stable disease, and three had progressive disease. The overall response rate (CR + PR) was 78%, and no severe adverse effects were observed. CONCLUSION: GSM-mediated chemoembolization showed good clinical efficacy in the treatment of liver metastases after gastrointestinal tumor surgery. However, larger cohort and clinical controlled studies are warranted.

To evaluate the safety and efficacy of transarterial arterial chemoembolization (TACE) with gelatin sponge particles (GSPs-TACE) and Huaier granule to treat primary hepatic carcinoma (PHC).A series of 62 patients with PHC were included between June 2009 and December 2011, and randomly assigned to a control (nâ=â31) or an experimental group (nâ=â31). The control patients received TACE with 350 to 560âµm GSPs plus lobaplatin chemotherapy. Patients in the experimental group received TACE plus Huaier granule. Treatment safety and mid-to-long-term efficacy were evaluated.Follow-up ranged from 12 to 24 months with a mean of 28.7 months. The 6- and 12-month overall survivals were 100% and 93.5% in the experimental group and 90.3% and 80.6% in control group, respectively. The difference in overall survival at 12 months was significant (χâ=â5.213, Pâ<â.05), but the difference in median survival in the experimental group (20.6 months) and control group (17.1 months) patients was not significant (χâ=â0.745, Pâ>â.05). The number of TACE procedures in the experimental group (2.9â±â8.7) and control group (4.1â±â7.3) patients was significantly different (χâ=â7.262, Pâ<â.05). The 6-month (87.1% vs. 73.3%, χâ=â5.945) and 12-month (72.4% vs. 64.3%, χâ=â6.384) tumor objective response rates in the experimental and control groups were significantly different (Pâ<â.05). There were no statistically significant differences in the occurrence of treatment-related adverse reactions in the 2 groups.Transarterial chemoembolization with GSPs and Huaier granule was safe and effective for treating PHC patients.

To retrospectively analyze the safety and efficacy of 350-560âµm gelatin sponge particles combined with single-chemotherapy drug transcatheter arterial chemoembolization (Gs-TACE) for the treatment of elderly hepatocellular carcinoma without surgical resection.Thirty elderly hepatocellular carcinoma patients without surgical resection, who received Gs-TACE in our hospital, were selected. Slowly injected gelatin sponge particles (350-560âµm)+ 10âmg lobaplatin injection into the regional embolization tumor target vessel. The Response Evaluation Criteria for Solid Tumors could be used to evaluate the tumor response after intervention surgery.Eighty-nine times of intervention TACE were conducted on the 30 patients. The average size of tumor was 8.3âcm. The median survival time was 28 months, and the 1 and 2-year survival rates were 89% and 58%, respectively. The Response Evaluation Criteria for Solid Tumors was used to evaluate the tumor response, and found that the complete response, partial response, and OR were 30%, 56.67%, and 86.67%, respectively, at 1 month after intervention surgery. The patients were divided into groups: 60 to 65 years age group (A), >65 to 75 years age group (B), and >75 years age group (C); the median survival times were 16, 32, and 33 months, respectively, and there was statistical difference between A group, B group, and C group. The analysis of prognosis factors showed that there was statistical significance in age, Barcelona Clinic Liver Cancer stage, portal vein invasion, and alpha fetal protein (AFP), and age was the protective factor.Gelatin sponge particles (350-560âµm), combined with transcatheter arterial chemoembolization, provide an alternative method for the treatment of elderly hepatocellular carcinoma without surgical resection.

Spontaneous rupture of hepatocellular carcinoma hemorrhage is life-threatening. The aim of the present study was to retrospectively analyze the effect of gelatin sponge microparticles (GSMs) of various diameters on the treatment of spontaneous rupture of hepatocellular carcinoma hemorrhage. GSMs serve as embolization agents by transcatheter arterial chemoembolization (TACE), and the current study analyzed their safety and efficacy. Data from a total of 13 cases of spontaneous rupture of hepatocellular carcinoma hemorrhage, who were treated with GSM-TACE at the Affiliated Zhongshan Hospital of Dalian University (Dalian, China) between August 2010 and June 2014, were collected. Post-operative complications were classified according to the National Cancer Institute Common Terminology Criteria. Review computed tomography was conducted 1, 3 and 6 months after GSM-TACE treatment in order to determine the occurrence of re-bleeding; the tumor response was evaluated based on the Modified Response Evaluation Criteria In Solid Tumors and the expression levels of α-feroprotein. The patients were followed-up for 1-6 months (average, 5.15±1.67 months). Following GSM-TACE treatment, 13 cases reached successful hemostasis without technical complications. The survival rates 1, 3 and 6 months after treatment were 76.9 (10/13), 61.5 (8/13) and 53.8% (7/13), respectively; the objective response rates were 61.6, 53.9 and 38.5%, respectively. The primary post-operative complications were pain (100%), nausea and vomiting (69.2%), and fever (53.8%). Among the 13 patients, 2 cases underwent surgical excision 10 and 30 days after GSM-TACE, and 1 case experienced re-bleeding 3 months after treatment, after which the patient received a second treatment with TACE and successful achieved hemostasis. In conclusion, GSM-TACE of various diameters is a safe and effective method in the treatment of spontaneous rupture of hepatocellular carcinoma hemorrhage. GSM-TACE is able to achieve immediate hemostasis and improves the survival rate of patients, thus creating favorable conditions for follow-up treatment.
ABSTRACT
Gelatin sponge particles are commonly used in the conventional transarterial chemoembolization (c-TACE) as an adjuvant embolizing agent for hepatocellular carcinoma (HCC). However, there are few reports regarding the clinical applications of gelatin sponge microparticles (GSMs) as a main embolizing agent in the treatment of HCC. This retrospective study aim to evaluate the efficacy and safety of patients with Barcelona Clinic Liver Cancer (BCLC) stage B HCC treated with intra-arterial injection of 350 to 560âµm GSMs mixed with anticancer agents.Twenty-four patients with unresectable BCLC stage B HCC without any prior treatment underwent transarterial chemoembolization with gelatin sponge microparticles (GSMs-TACE) of diameter 350 to 560âµm mixed with lobaplatin. The mixture was injected into tumor-feeding arteries until the sluggish flow in selective artery. Safety was measured by assessing complication rate, and efficacy was reflected by assessing response to mRECIST therapy and overall survival. The survival rate was calculated using the Kaplan-Meier method.All 24 BCLC stage B HCC patients showed good tolerance to the procedure. The mean follow-up period was 27 months and mean number of TACE treatments per patient was 3.7 sessions (range 1-10) during the follow-up period. Postprocedure complications were mild and treated by symptomatic treatment. Six months and 1 year overall survival rates were 100% and 87.5%, respectively. Overall median survival time was 25 months (95%CI: 21.06-28.95 months).GSMs-TACE is a safe and effective method for BCLC stage B HCC patients.
