Sarcopenia and myosteatosis are associated with survival in patients receiving immunotherapy for advanced hepatocellular carcinoma.

OBJECTIVES: To investigate the association of sarcopenia, myosteatosis, and sarcopenic obesity with survival outcomes among patients who underwent immunotherapy for advanced hepatocellular carcinoma (HCC). METHODS: In this retrospective analysis, patients who initiated immunotherapy for advanced HCC were enrolled. Sarcopenia and myosteatosis were evaluated on pretreatment CT at L3 level by skeletal muscle index and mean muscle attenuation using predefined cutoff values. Sarcopenic obesity was defined as concurrent sarcopenia and body mass index > 25 kg/m2. The log-rank test and the Cox proportional hazards model were used to compare overall survival (OS) and progression-free survival (PFS). RESULTS: A total of 138 patients was included (discovery cohort n = 111, validation cohort n = 27). In the discovery cohort, patients with sarcopenia exhibited significantly poorer PFS (p = 0.048) and OS (p = 0.002) than patients without sarcopenia. Patients with myosteatosis exhibited significantly poorer PFS (p < 0.001) and OS (p < 0.001) than patients without myosteatosis. Patients with sarcopenic obesity compared to patients without sarcopenic obesity exhibited significantly poorer OS (p = 0.006) but not PFS (p = 0.31). In multivariate analysis adjusting for patient demographics, tumor extent, and liver function reserve, myosteatosis remained an independent predictor of poor PFS (p = 0.014) and OS (p = 0.007); sarcopenia remained an independent predictor for poor OS (p = 0.007). The prediction models for survival outcomes built by the discovery cohort showed similar performance in the validation cohort. CONCLUSIONS: Sarcopenia and myosteatosis are independent prognostic factors in patients who received immunotherapy for advanced HCC. KEY POINTS: • Sarcopenia and myosteatosis can be evaluated by CT at L3 level. • Sarcopenia, myosteatosis, and sarcopenic obesity were associated with poor survival outcomes in patients who underwent immunotherapy for advanced HCC. • Myosteatosis was an independent predictor of PFS and OS, and sarcopenia was independent for OS in these patients.

Cancer-Associated Thrombosis: A Taiwanese Perspective on Therapeutic Options with Focus on Non-Vitamin K Antagonist Oral Anticoagulants.

Cancer-associated thrombosis (CAT) is a common complication of malignancies. Patients with CAT are at risk of venous thromboembolism recurrence, but also at risk of bleeding while anticoagulated. Taiwanese patients are perceived to have a lower incidence of CAT, likely leading to false reassurance for Taiwanese patients with cancer. Because of this, oncologists and cardiologists from multiple medical institutions in Taiwan have set forth to provide clinical consensus guidelines on the management of CAT, based on local clinical practices and guided by predominant international clinical practice guidelines. This paper aims to describe the current disease burden of cancer-associated venous thromboembolism in Taiwanese cancer patients, and discusses the unmet needs and gaps in the management of this medical complication. It also outlines diagnostic and management strategies relevant to the different treatment options available, such as non-vitamin K antagonist oral anticoagulants.

Low miR-10b-3p associated with sorafenib resistance in hepatocellular carcinoma.

BACKGROUND: Sorafenib is one of the standard first-line therapies for advanced hepatocellular carcinoma (HCC). Unfortunately, there are currently no appropriate biomarkers to predict the clinical efficacy of sorafenib in HCC patients. MicroRNAs (miRNAs) have been studied for their biological functions and clinical applications in human cancers. METHODS: In this study, we found that miR-10b-3p expression was suppressed in sorafenib-resistant HCC cell lines through miRNA microarray analysis. RESULTS: Sorafenib-induced apoptosis in HCC cells was significantly enhanced by miR-10b-3p overexpression and partially abrogated by miR-10b-3p depletion. Among 45 patients who received sorafenib for advanced HCC, those with high miR-10b-3p levels, compared to those with low levels, exhibited significantly longer overall survival (OS) (median, 13.9 vs. 3.5 months, p = 0.021), suggesting that high serum miR-10b-3p level in patients treated with sorafenib for advanced HCC serves as a biomarker for predicting sorafenib efficacy. Furthermore, we confirmed that cyclin E1, a known promoter of sorafenib resistance reported by our previous study, is the downstream target for miR-10b-3p in HCC cells. CONCLUSIONS: This study not only identified the molecular target for miR-10b-3p, but also provided evidence that circulating miR-10b-3p may be used as a biomarker for predicting sorafenib sensitivity in patients with HCC.

Cyclin-Dependent Kinase 9 Inhibition as a Potential Treatment for Hepatocellular Carcinoma.

PURPOSE: Composite cyclin-dependent kinase (CDK) inhibition has shown potential as a treatment for hepatocellular carcinoma (HCC) in preclinical studies. We tested whether the specific inhibition of CDK9 was effective against HCC. METHODS: The effects of two specific CDK9 inhibitors, BAY1143572 and AZD4573, in HCC cell lines were examined. We tested the in vivo efficacy of CDK9 inhibition in mouse xenograft models of HuH7 human HCC cells and in an orthotopic model of BNL mouse HCC cells. Overexpression and knockdown of CDK9 were performed to confirm the efficacy of CDK9 inhibition. RESULTS: CDK9 inhibitors exhibited potent antiproliferative activities in HCC cells regardless of the levels of c-myc expression while inhibiting the downstream signals of CDK9, such as the phosphorylation of RNA polymerase II. These 2 CDK9 inhibitors induced apoptosis in HCC cells and reduced the expression of antiapoptotic proteins such as myeloid cell leukemia-1 and survivin. In the xenograft studies, mice receiving either CDK9 inhibitor exhibited significantly slower tumor growth than did the mice receiving vehicles. In the orthotopic model, the HCC growth in mice receiving a CDK9 inhibitor also tended to be slower than that in the control group. Overexpression of CDK9 in HuH7 cells reduced the efficacy of both CDK9 inhibitors. Knockdown of CDK9 expression reduced the proliferative activities of HCC cells. CONCLUSION: We demonstrated the in vitro and in vivo activity of CDK9 inhibition on multiple HCC cell lines. Our data support further clinical development of CDK9 inhibitors as a treatment for HCC.

ICOS-Positive Regulatory T Cells in Hepatocellular Carcinoma: The Perspective from Digital Pathology Analysis.

INTRODUCTION: Inducible co-stimulator (ICOS), an important co-stimulatory receptor on effector T cells (Teffs), may also contribute to tumor growth due to its high expression on regulatory T cells (Tregs). This study explored the clinical significance of ICOS-expressing Tregs in hepatocellular carcinoma (HCC). METHODS: Tumor tissues from HCC patients who received curative hepatectomy were obtained at a referral center. Dual immunohistochemistry was performed to evaluate the expression of ICOS and Foxp3. The cell densities and proximities between stained cells in regions of interest were measured by digital pathology and the associations with clinical outcome were analyzed. RESULTS: A total of 142 patients (male:female = 112: 30, median age of 61.0 years) were enrolled. Among them, 87 (61.3%) had chronic hepatitis B virus infection and 33 (23.2%) had chronic hepatitis C infection. Low α-fetoprotein level (<20 ng/mL) and early-stage were significantly associated with improved overall survival (OS). The density of ICOS+Foxp3+ cells and the ratio of ICOS+Foxp3+/total Foxp3+ cells were significantly higher (p < 0.001) in the tumor center than in the peritumor area. Patients with a high density of ICOS+Foxp3+ cells or a high ratio of ICOS+Foxp3+/total Foxp3+ cells in the tumor center trended to have a shorter OS. A shorter distance between ICOS+Foxp3+ cells and ICOS+Foxp3- cells (likely Teffs) in the tumor center was significantly associated with a shorter OS (p = 0.030), suggesting active immunosuppression of ICOS+ Tregs on ICOS+ Teffs. CONCLUSION: An increased abundance of ICOS+ Tregs in the tumor center in comparison to the peritumor area indicates a strong immunosuppressive tumor microenvironment of HCC. A high proportion of ICOS+Foxp3+ cells and a shorter distance between ICOS+ Tregs and other ICOS+ cells were associated with a poor OS, suggesting that depleting ICOS+ Tregs might provide clinical benefit for patients with HCC.

Anti-PD-1 combined sorafenib versus anti-PD-1 alone in the treatment of advanced hepatocellular cell carcinoma: a propensity score-matching study.

BACKGROUND: Vascular endothelial growth factor (VEGF) plays a role in the tumor microenvironment. Sorafenib, which inhibits the VEGF pathway, has an immune-modulation function but lacks substantial clinical data. This study aims to explore the efficacy of anti-PD-1 combined sorafenib in advanced hepatocellular carcinoma (HCC). METHODS: HCC patients who underwent anti-PD-1 treatment at Taipei Veterans General Hospital (Taipei, Taiwan) between January 2016 and February 2019 were reviewed. The efficacy was compared between groups after propensity-score matching. RESULTS: There were 173 HCC patients receiving anti-PD-1. After excluding unsuitable cases, 140 patients were analyzed, of which 58 received combination therapy and 82 received anti-PD-1 alone. The combination therapy had a trend of higher CR rate (8.6% vs. 4.9%, ns.), ORR (22.4% vs. 19.5%, ns.) and significantly higher DCR (69.0% vs. 37.8%, p < 0.05) comparing to anti-PD-1 alone. After matching, combination group achieved longer progression-free survival (3.87 vs. 2.43 months, p < 0.05) and overall survival (not reached vs. 7.17 months, p < 0.05) than anti-PD-1 alone, without higher grade 3/4 AE (10.3% vs. 7.1%, p = 0.73). The tumor response varied among different metastatic sites, with high responses in adrenal glands, peritoneum and lungs. The more AFP declined (> 10, > 50 and > 66%), the higher the ORR (70, 80 and 92%) and CR rates (30, 35 and 58%) were achieved at day 28. CONCLUSIONS: This is the first study to demonstrate the combination of anti-PD-1 and sorafenib had better efficacy and survival benefit. A prospective randomized study is needed to confirm this finding.

Association of annexin A10 expression with poor prognosis of intrahepatic cholangiocarcinoma.

BACKGROUND: Annexin A10 expression influences the prognosis of several gastrointestinal cancers. We explored the association of annexin A10 expression with the overall survival (OS) of patients who underwent curative surgery for cholangiocarcinoma. METHODS: Patients who underwent curative surgery for cholangiocarcinoma (except gallbladder cancer) and had pathological stage T1-3N0M0 disease were enrolled. Annexin A10 expression was examined by performing immunohistochemical staining. Patient demographics and survival outcome data were retrieved from medical records. RESULTS: In total, 185 patients were enrolled. The primary tumor location was intrahepatic and extrahepatic (including the perihilar region) for 89% and 11% of patients, respectively. Positive annexin A10 staining was detected for 61 (33%) patients and associated with extrahepatic or perihilar cholangiocarcinoma (p = 0.001) and lower histological grade (p < 0.001). Patients with positive annexin A10 staining exhibited significantly poorer survival relative to patients with negative staining results (median OS, 2.5 vs. 4.9 years, p = 0.025). In the multivariate analysis adjusting for age, sex, tumor location, tumor grade, hepatitis infection, and disease stage, positive annexin A10 remained an independent predictor of poor OS (hazard ratio 1.572, p = 0.034). In the subgroup analysis, the association between annexin A10 and prognosis was restricted to intrahepatic cholangiocarcinoma. Among patients with intrahepatic cholangiocarcinoma, patients with positive annexin A10 staining exhibited significantly poorer survival compared with patients with negative annexin A10 staining (median OS, 2.3 vs. 4.9 years, p = 0.008). CONCLUSION: Positive annexin A10 expression was associated with poor prognosis of intrahepatic cholangiocarcinoma.

Bevacizumab and atezolizumab as first-line therapy for advanced hepatocellular carcinoma: A Taiwanese subgroup analysis on efficacy and safety.

BACKGROUND: The combination of bevacizumab and atezolizumab has been established as a standard first-line systemic treatment for unresectable hepatocellular carcinoma (HCC). We examined the treatment outcomes of patients in Taiwan who received the combination in 2 pivotal clinical trials. METHODS: All patients who resided in Taiwan, were enrolled in the IMbrave150 and GO30140 studies, and received bevacizumab and atezolizumab as the first-line systemic therapy for unresectable HCC were included. We extracted and pooled anonymous raw data from the study records. RESULTS: We enrolled 40 patients, with the median age of 62.5 years; 36 (90%) had Barcelona Clinic Liver Cancer stage C disease. The response rate was 37.5%, including 3 (7.5%) complete responses. The disease control rate was 85%. The median duration of response was 21.4 months (95% confidence interval [CI], 16.6-not estimable). The median progression-free survival (PFS) and overall survival (OS) were 8.6 (95% CI, 5.6-18.6) and 24.9 months (95% CI, 14.2-not estimable), respectively. The most common adverse events of all grades were proteinuria (50%) and hypertension (37.5%), the median onset of which were 157 and 127 days, respectively. Bevacizumab and atezolizumab treatment had to be interrupted in 20 (50%) and 13 (32.5%) patients, respectively. Among patients whose treatment duration was ≥6 months, 50% of them had to skip bevacizumab, but no signal of poorer PFS or OS was observed. CONCLUSION: In Taiwanese patients with advanced HCC, the efficacy and safety outcomes of bevacizumab and atezolizumab treatment were generally consistent with the global intent-to-treat populations.

An Underdiagnosed Hypothyroidism and Its Clinical Significance in Patients with Advanced Hepatocellular Carcinoma.

BACKGROUND: Many systemic therapies for advanced hepatocellular carcinoma (HCC) may cause hypothyroidism; however, in these patients, hypothyroidism prevalence before therapy and its prognostic impact remain unclear. MATERIALS AND METHODS: We previously established a prospective cohort of patients who received sorafenib as first-line therapy for advanced HCC. No patients had been clinically diagnosed with hypothyroidism before or during sorafenib treatment. We retrospectively determined the levels of thyrotropin and free thyroxine before initiation of systemic therapy. Hypothyroidism was defined as thyrotropin level higher than the upper limit of the normal range. Among patients with hypothyroidism, free thyroxine level less than the lower normal range was defined as overt hypothyroidism, and free thyroxine level within the normal range was defined as subclinical hypothyroidism. RESULTS: In total, 79 patients were enrolled; of them, 16 (20%) had hypothyroidism (overt hypothyroidism, 10; subclinical hypothyroidism, 6). Patients with hypothyroidism, compared with those without hypothyroidism, were more likely to be older than 65 years (56% vs. 29%, p = .037), have a serum α-fetoprotein level of >400 ng/mL (81% vs. 52%, p = .037), and have a significantly poorer overall survival (OS; median, 5.5 vs. 11.6 months, p = .043). After adjusting for other potential prognostic factors, hypothyroidism remained an independent predictor for poorer OS (hazard ratio, 2.53, p = .018). Patients with overt hypothyroidism and subclinical hypothyroidism exhibited similarly poor OS (p = .768). CONCLUSION: Underdiagnosis of hypothyroidism in patients with advanced HCC was common. Hypothyroidism, whether overt or subclinical, is associated with poor prognosis of advanced HCC. IMPLICATIONS FOR PRACTICE: The results of this study showed the underdiagnosis of hypothyroidism in patients with advanced hepatocellular carcinoma (HCC) and its influence on prognosis. These findings implied the importance of thyroid function check before initiation of systemic therapy for patients with advanced HCC.

Solving the deficit of cancer pain management skills by education programs.

BACKGROUND: Suboptimal cancer pain management is a worldwide problem. We examined whether an educational program on cancer pain management implemented during training could benefit primary care physicians. METHODS: We enrolled all the primary care physicians who visited the oncology ward at a medical center for the first time. Educational classes on cancer pain management were conducted. The participants' abilities in cancer pain management were measured in a pretest before the classes and approximately 2 weeks later in the first posttest. The second posttest was conducted on participants who visited the oncology ward again. All 3 tests had the same set of questions and were scored on a scale of 0 to 100. RESULTS: In total, 247 participants were enrolled. Less than 10% of them considered their previous education on cancer pain management adequate. The test scores increased significantly from the pretest to the first posttest (mean 65.6 vs. 89.7, p < 0.001). The participants' self-reported cancer pain management abilities, on a scale of 0 to 100, also improved significantly (mean 57.8 vs. 75.5, p < 0.001). The pretest scores were not associated with the participants' self-reported abilities or their perceptions about the adequacy of previous training on cancer pain management. The mean score on the second posttest, conducted 234.5 days after the program, on an average, remained similar to that of the first posttest (p = 0.254). CONCLUSION: A specific educational program on cancer pain management provided to primary care physicians improved their pain management skills substantially, with persistent effects.

Management consensus guideline for hepatocellular carcinoma: 2020 update on surveillance, diagnosis, and systemic treatment by the Taiwan Liver Cancer Association and the Gastroenterological Society of Taiwan.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality in Taiwan. The Taiwan Liver Cancer Association and the Gastroenterological Society of Taiwan had established a management consensus guideline in 2016. The current recommendations focus on updating critical issues regarding the management of HCC, including surveillance, diagnosis, and systemic treatment. For surveillance, the updated guideline suggests the role of dynamic computed tomography or magnetic resonance imaging and contrast-enhanced ultrasound (CEUS) in selected patients. For diagnosis, this update incorporates CEUS and recognizes the role of gadoxetic acid-enhanced magnetic resonance imaging. For systemic therapy, the updated guideline summarizes the multiple choices of targeted therapy, immune checkpoint inhibitors, and the combination of both. Through this update of the management consensus guideline, patients with HCC can benefit from receiving optimal diagnostic and therapeutic modalities.

The unique characteristic in peripheral immune cells in patients with advanced hepatocellular carcinoma.

BACKGROUND/PURPOSE: Recent progress in cancer immunology provides more insight in immune evasion of cancer cells. Cancer cells may achieve immune evasion through several ways including ineffective antigen presentation, T cell checkpoint utilization, immunosuppressive cytokines secretion and immunosuppressive cells recruitment. However, few literatures mentioned about the change of peripheral blood immune cells in advanced hepatocellular carcinoma (HCC) patients. To answer this question, we initiated a pilot study through detailed flow cytometry. METHODS: We enrolled patients with advanced HCC patients who had informed consent to the collection of their peripheral blood. We also recruited healthy individuals for the control group. Using flow cytometry, we analyzed lymphocyte subclasses and the PD-1 or PD-L1 positivity of immune cells in peripheral blood from HCC patients and healthy individuals. RESULTS: Twenty-four HCC patients were enrolled and twenty healthy individuals were enrolled. Most of the HCC patients were HBV carrier (58.3%), and the mean age was 61 years old. Among 55 immune cell parameters we examined in peripheral blood, 16 were significantly different between advanced HCC patients and healthy individuals by univariate analysis. Multivariate analysis was then conducted by fitting logistic regression model and showed that CD69-CD25- Naïve CD4αßT cell percentage and dendritic cell percentage can reasonably predict the advanced HCC status from peripheral blood. By our regression model, the adjusted generalized R2 = 0.918 and the estimated area under the Receiver Operating Characteristic (ROC) curve was 0.99. CONCLUSION: CD69-CD25- Naïve CD4αßT cell percentage and dendritic cell percentage in peripheral blood are highly correlated with the advanced HCC status. The change may result from immune evasion initiated by hepatocellular carcinoma cells and further investigation is warranted. Validation study is ongoing and this mechanism may be utilized to treat advanced HCC patient in the future.

Total skeletal, psoas and rectus abdominis muscle mass as prognostic factors for patients with advanced hepatocellular carcinoma.

PURPOSE: We investigated whether low skeletal muscle mass (LSMM) defined according to different muscle groups on computed tomography (CT) scans are predictive factors of survival for advanced hepatocellular carcinoma (HCC). METHODS: In this retrospective study, we analyzed patients who received sorafenib therapy for advanced HCC in a prospective patient cohort between 2007 and 2012. The total skeletal muscle (TSM), paraspinal muscle (PS), psoas muscle (PM), rectus abdominis (RA), and abdominal wall (AW) muscle areas were evaluated using a single CT slice at the third lumbar vertebra before treatment. LSMM was determined according to the TSM, PS, PM, RA and AW indices, which was calculated as the parameters divided by the square of the body height. RESULTS: We enrolled 137 patients. Women had significantly lower TSM index than men did (p < .001). Among men, the optimal cut points of the TSM, PM and RA indices for LSMM diagnosis were 39.1, 8.3 and 2.9 cm2/m2, respectively. Patients with LSMM defined by TSM (median 5.1 vs. 8.0 months, p = .007), PM (5.8 vs. 11.8 months, p < .001), and RA (7.2 vs. 8.1 months, p = .003) indices exhibited poorer overall survival than patients without LSMM. After adjusting for clinical variables, TSM (hazard ratio [HR]: 2.122, 95% confidence interval [CI]: 1.134-3.971) and PM (HR: 1.730, 95% CI: 1.058-2.828) indices-defined LSMM remained independent predictors for poor OS, but RA index-defined LSMM did not. CONCLUSION: LSMM defined by TSM and PM indices are independent predictors of poor prognosis for advanced HCC.

Revisiting Hepatic Artery Infusion Chemotherapy in the Treatment of Advanced Hepatocellular Carcinoma.

Hepatic artery infusion chemotherapy (HAIC) is a well-established and common treatment for advanced hepatocellular carcinoma (HCC), particularly in East Asia. However, HAIC is not recognized internationally. Although several trials have demonstrated the safety and efficacy of HAIC, evidence corroborating its overall survival (OS) benefits compared with standard treatments is insufficient. Nevertheless, HAIC may provide prominent benefits in selected patients such as patients with portal vein thrombosis or high intrahepatic tumor burden. Moreover, HAIC has been combined with several therapeutic agents and modalities, including interferon-alpha, multikinase inhibitors, radiation therapy, and immunotherapy, to augment its treatment efficacy. Most of these combinations appeared to increase overall response rates compared with HAIC alone, but results regarding OS are inconclusive. Two prospective randomized controlled trials comparing HAIC plus sorafenib with sorafenib alone have reported conflicting results, necessitating further research. As immunotherapy-based combinations became the mainstream treatments for advanced HCC, HAIC plus immunotherapy-based treatments also showed encouraging preliminary results. The trials of HAIC were heterogeneous in terms of patient selection, chemotherapy regimens and doses, HAIC combination agent selections, and HAIC technical protocols. These heterogeneities may contribute to differences in treatment efficacy, thus increasing the difficulty of interpreting trial results. We propose that future trials of HAIC standardize these key factors to reveal the clinical value of HAIC-based treatments for HCC.

A Multicenter Phase II Study of Second-Line Axitinib for Patients with Advanced Hepatocellular Carcinoma Failing First-Line Sorafenib Monotherapy.

LESSONS LEARNED: For patients with advanced hepatocellular carcinoma after failure of first-line sorafenib monotherapy, second-line axitinib provides modest efficacy with tolerable toxicity. The discrepant tumor responses and survival outcomes in trials using axitinib as salvage therapy highlight the importance of optimal patient selection with the aid of clinical biomarkers. BACKGROUND: Multikinase inhibitors have been effective treatment for hepatocellular carcinoma (HCC). This multicenter phase II study explored the efficacy and safety of second-line axitinib for advanced HCC. METHODS: Patients with advanced HCC and Child-Pugh A liver function, experiencing progression on first-line sorafenib monotherapy, were eligible. Axitinib 5 mg twice daily was given continuously with allowed dose escalation. Tumor assessment was performed according to RECIST version 1.1. The primary endpoint was rate of disease control. RESULTS: From April 2011 to March 2016, 45 patients were enrolled. Thirty-seven patients (82%) tested positive for hepatitis B surface antigen. The disease control rate was 62.2%, and the response rate was 6.7%, according to RECIST criteria. Median progression-free survival (PFS) and overall survival (OS) were 2.2 months and 10.1 months, respectively. Treatment-related adverse events were compatible with previous reports of axitinib. CONCLUSION: Second-line axitinib has moderate activity and acceptable toxicity for patients with advanced HCC after failing the first-line sorafenib monotherapy.

Early alpha-foetoprotein response associated with treatment efficacy of immune checkpoint inhibitors for advanced hepatocellular carcinoma.

BACKGROUND: Post-treatment decline in serum alpha-foetoprotein (AFP) levels has been shown to predict the treatment efficacy of antiangiogenic therapy for advanced hepatocellular carcinoma (HCC). We explored whether a decline in AFP levels was also associated with treatment outcomes of immune checkpoint inhibitors (ICIs) in patients with advanced HCC. METHODS: We reviewed all patients who received ICI therapy for advanced HCC. AFP response was evaluated in patients with the pretreatment AFP level of >20 ng/mL. We defined early AFP response as a >20% decline in serum AFP levels within the first 4 weeks of treatment initiation relative to pretreatment levels. We then studied whether early AFP response was associated with treatment outcomes. RESULTS: Sixty patients were enrolled in this study; 43 of them were evaluable for early AFP response. The objective response rate of early AFP responders was significantly higher than that of early AFP nonresponders (73% vs. 14%, P < .001). Early AFP responders, compared with early AFP nonresponders, exhibited significantly longer overall survival (OS) (median, 28.0 vs 11.2 months, P = .048) and progression-free survival (PFS) (median, 15.2 vs 2.7 months, P = .002). After adjusting for other clinicopathological variables and treatments, early AFP response remained an independent predictor for longer OS (hazard ratio [HR] = 0.089, 95% confidence interval [CI] = 0.018-0.441; P = .003) and PFS (HR = 0.128, 95% CI = 0.041-0.399; P < .001). CONCLUSION: Early AFP response was associated with higher treatment efficacy of ICIs for advanced HCC. Additional validation studies are nonetheless warranted.

Patients with head and neck cancer may need more intensive pain management to maintain daily functioning: a multi-center study.

PURPOSE: The purpose of this study is to investigate the prevalence of pain, pain management, and impact of recent pain on daily functioning in patients with head and neck cancer (HNC) and patients with other cancers. METHODS: This multi-center survey was conducted by using Brief Pain Inventory questionnaire to evaluate pain status and its impact on daily functioning. RESULTS: A total of 3289 patients were analyzed including 708 HNC patients and 2581 patients with other cancers. The overall pain prevalence was 69.17%. A higher percentage of HNC patients had recent pain (60.59 vs. 44.01%, P < 0.001), required pain management (86.29 vs. 72.03%, P < 0.001), and used any analgesics (53.81 vs. 34.52%, P < 0.001). HNC patients with pain management had a higher prevalence of recent pain (85.83 vs. 81.14%, P = 0.044) and a slightly lower satisfaction rate (74.00 vs. 79.70%, P = 0.070). Regarding the impact of pain on daily functioning, HNC patients had a lower mean interference score for general activity such as walking, normal work, sleep, and life enjoyment. CONCLUSIONS: The HNC patients may need more intensive pain management to achieve optimal pain control and maintain daily functioning.

A nationwide survey of adherence to analgesic drugs among cancer patients in Taiwan: prevalence, determinants, and impact on quality of life.

PURPOSE: Poor adherence to analgesic drugs is one of the most common barriers to adequate pain management. This prospective, cross-sectional, patient-oriented observational study aimed to explore the adherence rate, clinical factors, and impact of adherence to analgesic drugs on the quality of life (QoL) among cancer outpatients in Taiwan. METHODS: Eight hundred ninety-seven consecutive adult outpatients with cancer who had reported tumor pain and received regular analgesic drug treatment were enrolled from 16 medical centers across Taiwan. The Brief Pain Inventory was used to assess pain intensity and QoL. Morisky's four-item medication adherence scale was used to assess adherence to analgesic drugs. Clinical factors possibly associated with good adherence to analgesic drugs were analyzed using multivariate logistic regression analyses. RESULTS: Of the 897 patients, 26.9% met criteria for the good, 35.5% for the moderate, and 37.6% for the poor adherence groups. The good adherence group had significantly better QoL outcomes than the moderate and poor adherence groups (all p < 0.05). Age ≥ 50 years, head and neck or hematological malignancies, cancer-related pain, patients who agreed or strongly agreed that the side effects of analgesic drugs were tolerable, and patients who disagreed or strongly disagreed that the dosing schedule could be flexibly self-adjusted to deal with the actual pain were predictors of good adherence to analgesic drugs. CONCLUSIONS: Awareness of the clinical factors associated with adherence to analgesic drugs may help clinicians to identify cancer patients at a greater risk of non-adherence, reinforce optimal pain management, and improve the QoL by enhancing adherence to pain medications.

Right or left? Side selection for a totally implantable vascular access device: a randomised observational study.

BACKGROUND: Totally implantable vascular access device (TIVAD)-related complications interfere in the anticancer treatment and increase medical expenses. We examined whether the implantation side of central line TIVADs is associated with the occurrence of thrombotic or occlusion events. METHODS: We enrolled patients with cancer who required central line TIVADs and randomised them to receive the TIVAD implantation on either the left or right side. The primary endpoint was the occurrence of catheter-related thrombotic or occlusion events. RESULTS: We randomised 240 patients, of which 235 received TIVAD implantation according to the protocol. In the per-protocol cohort, 117 and 118 patients received implantation on the left and right sides, respectively. Catheter-related thrombotic or occlusion events occurred in 9 (4%) patients, accounting for 0.065 events per 1000 catheter-days. Between the patients with left- and right-sided implantations, the occurrence rates (P=0.333) and the time from catheter implantation to the occurrence of thrombotic or occlusion events (P=0.328) were both similar. In the multivariate analysis, the side of implantation remained unassociated with the occurrence of thrombotic or occlusion events. CONCLUSIONS: The side of central line TIVAD implantation was not associated with the occurrence of catheter-related thrombotic or occlusion events in patients with cancer.

National Policies Fostering Hospice Care Increased Hospice Utilization and Reduced the Invasiveness of End-of-Life Care for Cancer Patients.

BACKGROUND: In 2011, two national policies aiming to foster hospice services for terminal cancer patients took effect in Taiwan. The single-payer National Health Insurance of Taiwan started to reimburse full hospice services. The national hospital accreditation program, which graded all hospitals, incorporated hospice utilization in its evaluation. We assessed the impact of these national policies. METHODS: A cohort of 249,394 patients aged ≥18 years who died of cancer between 2008 and 2013 were identified from the National Death Registry. We retrieved utilization data of medical services and compared the health care utilization in the final month of life before and after the implementation of the new policies. RESULTS: After the policy changes, hospice utilization increased from 20.8% to 36.2%. In a multivariate analysis adjusting for patient demographics, cancer features, and hospital characteristics, hospice utilization significantly increased after 2011 (adjusted odds ratio [AOR] 2.35, p < .001), accompanied by a decrease in intensive care unit (ICU) admissions, invasive mechanical ventilation (IMV), and cardiopulmonary resuscitation (CPR; AORs 0.87, 0.75, and 0.80, respectively; all p < .001). The patients who received hospice services were significantly less likely to receive ICU admissions, IMV, and CPR (AORs 0.20, 0.12, and 0.10, respectively; all p < .001).
