Liver cancer: effects, safety, and cost-effectiveness of controlled-release oxycodone for pain control after TACE

Effect and Safety of Prophylactic Parecoxib for Pain Control of Transarterial Chemoembolization in Liver Cancer: A Single-Center, Parallel-Group, Randomized Trial

OBJECTIVE

Pain is one of the most common side effects of transarterial chemoembolization (TACE) in patients with unresectable hepatocellular carcinoma. The goal of this study is to compare the analgesic effect among celecoxib, parecoxib, and oxycodone in patients undergoing TACE.

METHODS

This prospective study was a randomized, paralleled trial in which 213 patients were enrolled. Patients were assigned at the ratio of 1:1:1 to receive celecoxib, parecoxib, or controlled-release oxycodone 1 hour before TACE (T0) and once every 12 hours for 2 days after TACE. Pain scores, pain intensity, and adverse events in each time interval were evaluated and compared among the 3 groups.

RESULTS

The mean pain score 12 hours after T0 in the parecoxib group (2.8) was lower than that in the celecoxib (4.4; P = .001) and oxycodone groups (4.2; P = .005). The number of patients suffering severe pain was 10 (14.7%) in the parecoxib, 25 (36.8%) in the celecoxib, and 23 (32.9%) in the oxycodone groups (P = .009). Twelve hours after T0, the incidence of grade 3 vomiting in the parecoxib group (2.9%) was significantly lower than that in the oxycodone group (17.1%; P = .006). In the multivariate analysis, nonparecoxib prophylactic analgesia (odds ratio [OR], 4.620; 95% confidence interval [CI], 1.877-11.370; P = .001) as well as embolization of the gallbladder (OR, 8.666; 95% CI, 2.402-31.262; P = .001) and normal liver parenchyma (OR, 3.278; 95% CI, 1.409-7.627; P = .006) were the independent factors of severe pain intensity 12 hours after T0.

CONCLUSION

Parecoxib is superior to oxycodone and celecoxib for pain control with fewer adverse events. Therefore, we recommend parecoxib as a priority strategy for TACE-related pain control.

Intraarterial Lidocaine Administration for Pain Control by Water-in-Oil Technique in Transarterial Chemoembolization: in vivo and Randomized Clinical Trial

Objective

To investigate the sustained release of lidocaine from a lidocaine–epirubicin–lipiodol emulsion created by water-in-oil (W/O) technique in vivo and evaluate the efficacy and safety of intraarterial lidocaine administration for intra- and postoperative pain control in transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).

Methods

The in vivo concentrations of lidocaine were determined in tumor tissues after VX2 rabbit models for hepatic tumor were administered with intra-arterial lidocaine–epirubicin–lipiodol emulsion. A prospective randomized controlled clinical trial was performed, enrolling 70 consecutive patients who underwent TACE. Patients were randomized into two groups: Group A received an immediate bolus intraarterial lidocaine injection before TACE, and Group B received a lidocaine–epirubicin–lipiodol emulsion during TACE. Pain intensity was compared between the two groups using a visual analog scale (VAS) score before (T_before) and at 0 h (T₀), 4 h (T₄), 8 h (T₈), 24 h (T₂₄), 48 h (T₄₈), and 72 h (T₇₂) after the procedure. Adverse events and intake of analgesics were evaluated and compared between the two groups.

Results

The concentrations of lidocaine in tumor tissues were higher in experimental group than in control group at T_0.5 (P=0.004), T₁ (P=0.038), T₄ (P=0.036), and T₈ (P=0.029). In the clinical trial, VAS scores in Group B were significantly lower than in Group A at T₀ (P=0.006), T₄ (P=0.001), T₈ (P=0.002), and T₂₄ (P=0.005). The tramadol intake in Group B was significantly lower than in Group A (P=0.021). No significant difference was observed regarding the incidence of adverse events between the two groups.

Conclusion

This study demonstrated the effectiveness and safety of intraarterial lidocaine administration using the W/O technique in controlling intra- and post-TACE pain.

Dexamethasone prevents TACE-induced adverse events: A meta-analysis

BACKGROUND

While dexamethasone has been applied following transcatheter arterial chemoembolization (TACE) for years, its clinical effects have not been determined. In the current study, we aimed to evaluate the efficacy of dexamethasone in preventing adverse events induced by TACE.

METHODS

Literature retrieval was conducted using globally recognized online databases, namely MEDLINE, EMBASE, and Cochrane Central, to identify randomized controlled trials (RCTs) of dexamethasone application in patients undergoing TACE. The relative odds ratios (ORs) of incidence rates of three adverse events, namely, fever, abdominal pain and nausea/vomiting, were calculated. The value of I was applied to evaluate the heterogeneity of the trials, and the overall publication bias was assessed with Egger test.

RESULTS

Four RCTs containing 350 subjects were included for the pooled estimation. Dexamethasone significantly reduced the incidence rate of TACE-induced adverse events (OR = 1.237, 95% CI: 1.170-1.308, P < .001) with moderate heterogeneity (I = 46.0%). The result of Egger test revealed a publication bias for the included studies.

CONCLUSION

The current meta-analysis confirmed the efficacy of dexamethasone in preventing TACE-induced adverse events. To confirm the practicality of dexamethasone use with TACE, further studies with large sample sizes are warranted to update the evidence-based analyses.

Predictive model for acute abdominal pain after transarterial chemoembolization for liver cancer

BACKGROUND

Transarterial chemoembolization (TACE) is the first-line treatment for patients with unresectable liver cancer; however, TACE is associated with postembolization pain.

AIM

To analyze the risk factors for acute abdominal pain after TACE and establish a predictive model for postembolization pain.

METHODS

From January 2018 to September 2018, all patients with liver cancer who underwent TACE at our hospital were included. General characteristics; clinical, imaging, and procedural data; and postembolization pain were analyzed. Postembolization pain was defined as acute moderate-to-severe abdominal pain within 24 h after TACE. Logistic regression and a classification and regression tree were used to develop a predictive model. Receiver operating characteristic curve analysis was used to examine the efficacy of the predictive model.

RESULTS

We analyzed 522 patients who underwent a total of 582 TACE procedures. Ninety-seven (16.70%) episodes of severe pain occurred. A predictive model built based on the dataset from classification and regression tree analysis identified known invasion of blood vessels as the strongest predictor of subsequent performance, followed by history of TACE, method of TACE, and history of abdominal pain after TACE. The area under the receiver operating characteristic curve was 0.736 [95% confidence interval (CI): 0.682-0.789], the sensitivity was 73.2%, the specificity was 65.6%, and the negative predictive value was 92.4%. Logistic regression produced similar results by identifying age [odds ratio (OR) = 0.971; 95%CI: 0.951-0.992; P = 0.007), history of TACE (OR = 0.378; 95%CI: 0.189-0.757; P = 0.007), history of abdominal pain after TACE (OR = 6.288; 95%CI: 2.963-13.342; P < 0.001), tumor size (OR = 1.978; 95%CI: 1.175-3.330; P = 0.01), multiple tumors (OR = 2.164; 95%CI: 1.243-3.769; P = 0.006), invasion of blood vessels (OR = 1.756; 95%CI: 1.045-2.950; P = 0.034), and TACE with drug-eluting beads (DEB-TACE) (OR = 2.05; 95%CI: 1.260-3.334; P = 0.004) as independent predictive factors for postembolization pain.

CONCLUSION

Blood vessel invasion, TACE history, TACE with drug-eluting beads, and history of abdominal pain after TACE are predictors of acute moderate-to-severe pain. The predictive model may help medical staff to manage pain.

Risk Factors for Postembolization Syndrome After Transcatheter Arterial Chemoembolization

BACKGROUND

Transarterial Chemoembolization (TACE) is a minimally invasive treatment in managing unresectable liver primary neoplasms or liver metastases. Postembolization Syndrome (PES) is the most common adverse effect after TACE procedures.

OBJECTIVE

We investigate the risk factors for the development of PES after TACE therapy in patients with primary or metastatic liver tumors.

METHODS

In a retrospective analysis of 163 patients who underwent TACE between 01/01/2012 and 31/01/2018, patients that were given medication due to pain, fever, nausea or vomiting were evaluated and noted with PES. Analyses were made to evaluate factors such as age, gender, chemotherapy agent and dose, tumor size, tumor type, a particle used for embolization, multiple tumor treatments and selective application of the procedure, which may lead to PES after TACE.

RESULTS

In a total of 316 patients, PES was observed at a rate of 55 percent after TACE. Tumor size, number of tumors treated and adopting super selective fashion in the procedure were found to be related to the development of PES. No relationship was found between age, gender, presence of ascites, tumor type, size of embolic agent and drug type and the development of PES.

CONCLUSION

A treated tumor measuring >5 cm, treating more than one tumor, and the failure to perform the procedure in a super selective fashion increase the risk of PES development after TACE.

Novel multimodal analgesia regimen improves post-TACE pain in patients with hepatocellular carcinoma

BACKGROUD

Transarterial chemoembolization (TACE) is the primary palliative treatment for patients with unresectable hepatocellular carcinoma (HCC). However, it is often accompanied by postoperative pain which hinder patient recovery. This study was to examine whether preemptive parecoxib and sufentanil-based patient controlled analgesia (PCA) could improve the pain management in patients receiving TACE for inoperable HCC.

METHODS

From June to December 2016, 84 HCC patients undergoing TACE procedure were enrolled. Because of the willingness of the individuals, it is difficult to randomize the patients to different groups. We matched the patients' age, gender and pain scores, and divided the patients into the multimodal group (n = 42) and control group (n = 42). Patients in the multimodal group received 40 mg of parecoxib, 30 min before TACE, followed by 48 h of sufentanil-based PCA. Patients in the control group received a routine analgesic regimen, i.e., 5 mg of dezocine during operation, and 100 mg of tramadol or equivalent intravenous opioid according to patient's complaints and pain intensity. Postoperative pain intensity, percentage of patients as per the pain category, adverse reaction, duration of hospital stay, cost-effectiveness, and patient's satisfaction were all taken into consideration when evaluated.

RESULTS

Compared to the control group, the visual analogue scale scores for pain intensity was significantly lower at 2, 4, 6, and 12 h (all P < 0.05) in the multimodal group and a noticeably lower prevalence of post-operative nausea and vomiting in the multimodal group (31.0% vs. 59.5%). Patient's satisfaction in the multimodal group was also significantly higher than that in the control group (95.2% vs. 69.0%). No significant difference was observed in the duration of hospital stay between the two groups.

CONCLUSION

Preemptive parecoxib and sufentanil-based multimodal analgesia regime is a safe, efficient and cost-effective regimen for postoperative pain control in HCC patients undergoing TACE.

Health education helps to relieve postembolization pain during hepatic arterial chemoembolization therapy

Aim

Psychological intervention has been proved a complementary approach to drug analgesia. Another study suggested that health knowledge is associated with psychological symptoms in patients with liver cancer. This study is conducted to assess whether improving the health education (HE) alleviates the postembolization pain during transarterial chemoembolization (TACE).

Materials and methods

One hundred and fifteen patients, who required TACE for hepatocellular carcinoma (HCC) and suffered postembolization pain, were randomized into control group (n=63) and HE group (n=52). The health knowledge was scaled with the health knowledge questionnaire (HKQ). The postembolization pain was scored using a 0–10 numeric rating scale (NRS-10) after arterial embolization in both groups.

Results

There were no statistical differences between male and female in all HKQ scores (P>0.05). The HKQ scores of young people (≤45 years old) were significantly higher than those of elders (>45 years old; P<0.05). After teaching HE, the HKQ scores were significantly increased in patients of the HE group (P<0.01). The postembolization pain score in the HE group was significantly lower than that in the control group (P<0.05). The HKQ scores of question 1, 3, and total were negatively correlated with the pain score in this sample (P<0.05).

Conclusion

Improving the HE among HCC patients before TACE is beneficial for the pain relief during interventional procedure.

125I seed brachytherapy versus external beam radiation therapy for the palliation of painful bone metastases of lung cancer after one cycle of chemotherapy progression

Purpose

This study aimed to compare the outcomes of ¹²⁵I seed brachytherapy versus external beam radiation therapy (EBRT) for the palliation of painful bone metastases of lung cancer after one cycle of chemotherapy progression.

Materials and methods

We analyzed retrospectively 158 patients with painful bone metastases secondary to lung cancer after one cycle of chemotherapy progression treated between June 2013 and May 2016. Seventy-six patients with 96 lesions received ¹²⁵I brachytherapy (Group A), whereas 82 patients with 98 metastases received EBRT (Group B). Pain intensity on Brief Pain Inventory, percentage of patients with pain severity, and quality of life were recorded prior to treatment (T₀), 2, 4, 6, 8, 12, 16, 20, and 24 weeks (T₂, T₄, T₆, T₈, T₁₂, T₁₆, T₂₀, and T₂₄) after treatment during a 24-hour period. Cost-effectiveness and number of treatment appointments were also compared between groups.

Results

One hundred and fifty-eight patients had been treated. Visual analog scale for worst pain in Group A was significantly lower than in Group B at T₂, T₄, T₆, T₁₆, T₂₀, and T₂₄. Group A was superior to group B concerning quality of life scores (T₂, T₄, T₂₀, and T₂₄), cost-effectiveness, and number of treatment appointments. No significant differences were observed for complications.

Conclusion

Compared with EBRT, ¹²⁵I seed brachytherapy can be an alternative method for painful bone metastases from lung cancer after one cycle of chemotherapy progression.

Postoperative local incision analgesia for acute pain treatment in patients with hepatocellular carcinoma

OBJECTIVE

The present study aimed to investigate the analgesic effect and safety of using local incision analgesia to treat acute postoperative pain in patients with hepatocellular carcinoma (HCC).

METHOD

A cohort of 60 patients undergoing liver cancer resection was randomly divided into three groups (n=20 per group): local incision analgesia (LIA) group, which received local infiltration with ropivacaine combined with a postoperative analgesia pump; intravenous patient-controlled analgesia (PCA) group, which received fentanyl intravenous analgesia postoperatively; and the control group, which received tramadol hydrochloride injection postoperatively according to the NRS scoring system. The postoperative analgesic effect in each group was compared and tumor recurrence (survival) was analyzed using the Kaplan-Meier method.

RESULTS

NRS scores, rate of analgesic usage, ambulation time (h) and intestinal function recovery time (h) were significantly reduced in LIA group compared with the control group at each postoperative time point (6, 12, 24 and 48 hours; p<0.05). Additionally, the NRS scores of LIA patients at 12 hours post-surgery was significantly reduced compared with PCA group (p<0.05), and the occurrence of postoperative adverse events in LIA group was significantly lower than that in PCA group (p<0.05). Survival analysis demonstrated that the mean survival time (tumor recurrence) was significantly increased in LIA group compared with the control group (χ2=4.749; p=0.029).

CONCLUSION

Local incision analgesia improves the analgesic effect, causes fewer adverse reactions and increases postoperative survival time. Our study demonstrated that local incision analgesia is a safe and effective method of postoperative pain management following hepatectomy.

Management of Postembolization Syndrome Following Hepatic Transarterial Chemoembolization for Primary or Metastatic Liver Cancer

BACKGROUND

Transarterial chemoembolization (TACE) is an established treatment in managing liver primary neoplasms or liver metastases. Postembolization syndrome (PES) is a common adverse event defined as fever without associated sepsis, pain in the right upper quadrant, and nausea and/or vomiting.

OBJECTIVE

This integrative review aims to identify effective management strategies for PES or one of its characterizing symptoms (fever, pain, and nausea and/or vomiting).

METHODS

Searches of electronic databases MEDLINE, EMBASE, and CINAHL were conducted. Fifteen articles were identified for inclusion. Seven addressed all symptoms of PES, and 8 studies focused on individual symptoms of PES.

RESULTS

Interventions identified are intra-arterial lidocaine, oral and intravenous analgesics, steroids, wrist-ankle acupuncture, antibiotics, and 5-HT3 receptor antagonists. Findings are explicated according to individual symptoms of PES. Intra-arterial lidocaine, steroids, and a 5-HT3 receptor antagonist are found to offer potential benefit in the management of PES symptoms.

CONCLUSION

A number of interventions have shown potential benefit in the management of PES. A systemic approach using combination therapy is necessary to effectively manage characterizing symptoms. Further research is needed to determine the impact of primary disease site, TACE technique, and chemotherapeutic agent on PES.

IMPLICATIONS FOR PRACTICE

Oncology nurses are uniquely placed to undertake thorough patient assessment after TACE and implement early intervention to effectively manage PES.

Risks factors for severe pain after selective liver transarterial chemoembolization

BACKGROUND & AIMS

Post-procedural pain is frequent after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC), and is only partially prevented by treatment selectivity. Our aim was to determine the risk factors of severe pain after selective TACE for HCC.

METHODS

From January 2012 to June 2014, all treatment-naïve patients undergoing a first selective TACE were included. Risk factors for severe pain, that is, the need for opioid analgesics (grade II-III), were identified by uni- and multivariate analysis. Internal validation of a logistic regression model for prediction of opioid intake was done with bootstrapping.

RESULTS

We analysed 335 tumours (mean 47 ± 37 mm) in 159 patients (131 men), mean 63.4 years old (20-92). Twenty-seven patients (17%) requested opioids. In univariate analysis, opioid intake was associated with young age (P=.021), doxorubicin dose received (P=.031), large HCC (P=.038), absence of chronic liver disease (P<.001) and alpha-foetoprotein levels (P=.03). In multivariate analysis, opioid intake was associated with young age (OR=0.65 per 10 years increment, P=.048), absence of chronic liver disease (OR=31.7, P<.001) and a higher fraction of the doxorubicin dose (OR=1.32 per 10% increment, P=.009). The optimism-corrected area under the curve of the prediction model for opioid intake using these three factors was 0.751.

CONCLUSION

In patients with HCC treated with TACE, selective procedure does not always prevent from severe pain. Young patients without chronic liver disease may be more susceptible to severe pain.

Correlation between liver cancer pain and the HIF-1 and VEGF expression levels

A possible correlation between liver cancer pain and the hypoxia-inducible factor (HIF)-1 and vascular endothelial growth factor (VEGF) expression levels was examined. From January, 2015 to January, 2016, 30 patients suffering from liver cancer with pain, 30 patients with liver cancer without pain and 30 hepatitis patients with pain were enrolled in the study. Pain level was evaluated by visual analogue scale (VAS), the expression levels of HIF-1 and VEGF mRNA were determined by RT-PCR and the expression levels of HIF-1 and VEGF proteins were examined by ELISA. Before intervention, the VAS in the hepatitis group was significantly higher than that of the liver cancer pain group. However, after intervention the VAS in the two groups was reduced. HIF-1 and VEGF mRNA expression levels in the liver cancer pain group were significantly higher than those in the liver cancer group before and after intervention. The expression levels of HIF-1 and VEGF mRNA in the hepatitis group were the lowest. The expression levels of HIF-1 and VEGF mRNA in the liver cancer pain group considerably increased after intervention. The expression levels of HIF-1 and VEGF mRNA in the other two groups showed no changes before or after intervention. Before and after the intervention, VAS in the liver cancer pain group was positively correlated to the expression levels of HIF-1 and VEGF. Thus, pain occurrence and the pain level in liver cancer patients were correlated with the expression levels of HIF-1 and VEGF. As the regular three-step medicine analgesic ladder is ineffective in these cases, verification of HIF-1 and VEGF expression levels may be considered the new target for pain release.

Quality of pharmacoeconomic research in China: A systematic review

BACKGROUND

The number of pharmacoeconomic publications in the literature from China has risen rapidly, but the quality of pharmacoeconomic publications from China has not been analyzed.

OBJECTIVES

This study aims to identify all recent pharmacoeconomic publications from China, to critically appraise the reporting quality, and to summarize the results.

METHODS

Four databases (PubMed, Web of Science, Medline, and EmBase) were searched for original articles published up to December 31, 2014. The Consolidated Health Economic Evaluation Reporting Standards statement including 24 items was used to assess the quality of reporting of these articles.

RESULTS

Of 1046 articles identified, 32 studies fulfilled the inclusion criteria. They were published in 23 different journals. Quality of reporting varied between studies, with an average score of 18.7 (SD = 4.33) out of 24 (range 9-23.5). There was an increasing trend of pharmacoeconomic publications and reporting quality over years from 2003 to 2014. According to the Consolidated Health Economic Evaluation Reporting Standards, the reporting quality for the items including "title," "comparators of method," and "measurement of effectiveness" are quite low, with less than 50% of studies fully satisfying these reporting standards. In contrast, reporting was good for the items including "introduction," "study perspective," "choice of health outcomes," "study parameters," "characterizing heterogeneity," and "discussion," with more than 75% of the articles satisfying these reporting criteria. The remaining items fell in between these 2 extremes, with 50% to 75% of studies satisfying these criteria.

CONCLUSION

Our study suggests the need for improvement in a number of reporting criteria. But the criteria for which reporting quality was low seem to be limitations that would be straightforward to correct in future studies.

Effect of perioperative parecoxib sodium on postoperative pain control for transcatheter arterial chemoembolization for inoperable hepatocellular carcinoma: a prospective randomized trial

OBJECTIVES

Pain is one of the most common side effects of transcatheter arterial chemoembolization (TACE) treatment. This study aimed to assess the analgesic effect of parecoxib sodium for postoperative pain control in patients with inoperable hepatocellular carcinoma (HCC) undergoing TACE.

MATERIALS AND METHODS

This randomized placebo-controlled prospective clinical study was conducted at a single cancer centre. Patients were randomly assigned to receive parecoxib sodium (experimental group; n = 60) or 0.9 % sodium chloride (control group; n = 60) 1 h before TACE and once every 12 h for 2 days after TACE. Pain level, morphine consumption, adverse events, and quality of life were evaluated and compared between the two groups.

RESULTS

Pain scores, percentage distribution of pain categories, and morphine consumption were significantly lower in the experimental group than in the control group (P < 0.05). Fever score comparisons revealed significantly better body temperature balance in the experimental group than in the control group (P = 0.024). Quality-of-life scores in the experimental group were significantly better than those in the control group (P < 0.05).

CONCLUSIONS

Our results demonstrate that the perioperative administration of parecoxib significantly improved its effectiveness in the control of postoperative pain after TACE.

KEY POINTS

• Perioperative administration of parecoxib is effective for control of pain after TACE. • COX-2 inhibitors provide effective and safe pain control. • Parecoxib helps improve quality-of-life after TACE for patients with inoperable hepatocellular carcinoma.

Guidelines on the use of gelatin sponge particles in embolotherapy

Gelatin sponge (GS) is one of the most widely used embolic agents in interventional procedures. There are four commercially available GS products in Japan; however, the endovascular use of Gelfoam and Spongel is off-label, and Gelpart can only be used for hepatic artery embolization and Serescue can only be used for hemostasis of arterial bleeding. GS has been used for a variety of clinical indications, mainly tumor embolization and stopping massive arterial bleeding. The optimal size and preparation procedure of GS particles differs slightly for each clinical indication. In addition, there is a risk of ischemic and/or infectious complications associated with GS embolization in various situations. Therefore, radiologists should be familiar with not only the preparation and handling of GS particles, but also the disadvantages and potential risks, in order to perform GS embolization safely and effectively.
