RESUMO

BACKGROUND/OBJECTIVES: Liposomal irinotecan plus 5-fluorouracil and leucovorin (nal-IRI + 5-FU/LV) provides survival benefits for metastatic pancreatic adenocarcinoma (mPDAC) refractory to gemcitabine-based treatment, mainly gemcitabine plus nab-paclitaxel (GA), in current practice. Gemcitabine plus S-1 (GS) is another commonly administered first-line regimen before nab-paclitaxel reimbursement; however, the efficacy and safety of nal-IRI + 5-FU/LV for mPDAC after failed GS treatment has not been reported and was therefore explored in this study. METHODS: In total, 177 patients with mPDAC received first-line GS or GA treatment, followed by second-line nal-IRI + 5-FU/LV treatment (identified from a multicenter retrospective cohort in Taiwan from 2018 to 2020); 85 and 92 patients were allocated to the GS and GA groups, respectively. Overall survival (OS), time-to-treatment failure (TTF), and adverse events were compared between the two groups. RESULTS: The baseline characteristics of the two groups were generally similar; however, a higher median age (67 versus 62 years, p < 0.001) and fewer liver metastases (52% versus 78%, p < 0.001) were observed in the GS versus GA group. The median OS was 15.0 and 15.9 months in the GS and GA groups, respectively (p = 0.58). The TTF (3.1 versus 2.8 months, p = 0.36) and OS (7.6 versus 6.7 months, p = 0.83) after nal-IRI treatment were similar between the two groups. More patients in the GS group developed mucositis during nal-IRI treatment (15% versus 4%, p = 0.02). CONCLUSIONS: The efficacy of second-line nal-IRI +5-FU/LV treatment was unaffected by prior S-1 exposure. GS followed by nal-IRI treatment is an alternative treatment sequence for patients with mPDAC.

RESUMO

BACKGROUND: Objective structured clinical examination (OSCE) is used worldwide. This study aims to explore potential alternatives to the OSCE by using entrustable professional activities (EPA)-based assessments in the workplace. METHODS: This study enrolled 265 six-year undergraduate medical students (UGY) from 2021 to 2023. During their rotations, students were assessed using 13 EPAs, with the grading methods modified to facilitate application. Before graduation, they participated in two mock OSCEs and a National OSCE. We used generalized estimating equations to analyze the associations between the EPA assessments and the OSCE scores, adjusting for age and sex, and developed a prediction model. EPA8 and EPA9, which represent advanced abilities that were not significant in the regression models, were removed from the prediction model. RESULTS: Most EPAs were significantly correlated with OSCE scores across the three cohorts. The prediction model for forecasting passing in the three OSCEs demonstrated fair predictive capacity (area under curve = 0.82, 0.66, and 0.71 for students graduated in 2021, 2022, and 2023, respectively all p < 0.05). CONCLUSIONS: The workplace-based assessments (EPA) showed a high correlation with competency-based assessments in simulated settings (OSCE). EPAs may serve as alternative tools to formal OSCE for medical students.

RESUMO

OBJECTIVE: Stromal barriers, such as the abundant desmoplastic stroma that is characteristic of pancreatic ductal adenocarcinoma (PDAC), can block the delivery and decrease the tumour-penetrating ability of therapeutics such as tumour necrosis factor-related apoptosis-inducing ligand (TRAIL), which can selectively induce cancer cell apoptosis. This study aimed to develop a TRAIL-based nanotherapy that not only eliminated the extracellular matrix barrier to increase TRAIL delivery into tumours but also blocked antiapoptotic mechanisms to overcome TRAIL resistance in PDAC. DESIGN: Nitric oxide (NO) plays a role in preventing tissue desmoplasia and could thus be delivered to disrupt the stromal barrier and improve TRAIL delivery in PDAC. We applied an in vitro-in vivo combinatorial phage display technique to identify novel peptide ligands to target the desmoplastic stroma in both murine and human orthotopic PDAC. We then constructed a stroma-targeted nanogel modified with phage display-identified tumour stroma-targeting peptides to co-deliver NO and TRAIL to PDAC and examined the anticancer effect in three-dimensional spheroid cultures in vitro and in orthotopic PDAC models in vivo. RESULTS: The delivery of NO to the PDAC tumour stroma resulted in reprogramming of activated pancreatic stellate cells, alleviation of tumour desmoplasia and downregulation of antiapoptotic BCL-2 protein expression, thereby facilitating tumour penetration by TRAIL and substantially enhancing the antitumour efficacy of TRAIL therapy. CONCLUSION: The co-delivery of TRAIL and NO by a stroma-targeted nanogel that remodels the fibrotic tumour microenvironment and suppresses tumour growth has the potential to be translated into a safe and promising treatment for PDAC.

RESUMO

BACKGROUND: The objective of this study was to evaluate the efficacy and safety of induction chemotherapy (ICT), GOFL (gemcitabine, oxaliplatin plus fluorouracil (5-FU)/leucovorin) versus modified FOLFIRINOX (irinotecan, oxaliplatin plus 5-FU/leucovorin), followed by concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic adenocarcinoma (LAPC). METHODS: Chemo-naive patients with measurable LAPC were eligible and randomly assigned to receive biweekly ICT with either mFOLFIRINOX or GOFL for 3 months. Patients without systemic progression would have 5-FU- or gemcitabine-based CCRT (5040 cGy/28 fractions) and were then subjected to surgery or continuation of chemotherapy until treatment failure. The primary endpoint was 9-month progression-free survival (PFS) rate. RESULTS: Between July 2013 and January 2019, 55 patients were enrolled. After ICT, 21 (77.8%) of 27 patients who received mFOLFIRINOX and 17 (60.7%) of 28 patients who received GOFL completed CCRT. Of them, one and five had per-protocol R0/R1 resection. On intent-to-treat analysis, the 9-month PFS rate, median PFS and overall survival in mFOLFIRINOX and GOFL arms were 30.5% versus 35.9%, 6.6 (95% confidence interval: 5.9-12.5) versus 7.6 months (3.9-12.3) and 19.6 (13.4-22.9) versus 17.9 months (13.4-23.9), respectively. Grade 3-4 neutropenia and diarrhoea during induction mFOLFIRINOX and GOFL were 37.0% versus 21.4% and 14.8% versus 3.6%, respectively. CONCLUSION: Induction GOFL and mFOLFIRINOX followed by CCRT provided similar clinical outcomes in LAPC patients. GOV IDENTIFIER: NCT01867892.

RESUMO

BACKGROUND: Bullous pemphigoid (BP) is a common autoimmune blistering skin disease with substantial mortality. OBJECTIVE: To identify whether the use of immunosuppressants was associated with reduced mortality in BP patients. METHODS: The data for this study were obtained from the National Health Insurance Research Database in Taiwan from January 1, 1997 to December 31, 2013. Those BP patients receiving any immunosuppressant for ≥28 days per month for 3 consecutive months were defined as the immunosuppressant cohort. In total, 452 BP patients on immunosuppressants were matched 1:4 by age, sex, propensity score of comorbidities, and use of tetracycline with 1,808 BP patients taking only corticosteroids. RESULTS: The immunosuppressant cohort had a significantly lower 5-year mortality rate than the corticosteroid cohort (0.57 vs. 0.67). In the multivariable regression analysis adjusted for covariates, the use of immunosuppressants significantly reduced the risk of mortality (hazard ratio [HR]: 0.78, 95% confidence interval [CI]: 0.68-0.90, p < 0.001). Hyperlipidemia also reduced risk of mortality. However, age, diabetes, renal disease, chronic obstructive pulmonary disease, cerebrovascular disease, and dementia were significant risk factors for mortality. In the subgroup analysis, the risk of mortality decreased most substantially in those aged <70 years (HR: 0.45, 95% CI: 0.28-0.72). CONCLUSION: Immunosuppressant use was associated with a 22% reduced risk of BP mortality. The effects were more substantial in those aged <70 years, with a 55% reduced risk of mortality.

RESUMO

There are no data comparing the efficacy and safety of prophylactic entecavir (ETV), tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) for HBV-infected cancer patients undergoing chemotherapy. This study aimed to compare the efficacy and renal safety of ETV, TDF and TAF in this setting. HBsAg-positive cancer patients treated with ETV (n = 582), TDF (n = 200) and TAF (n = 188) during chemotherapy were retrospectively enrolled. Antiviral efficacy and risk of renal events were evaluated. The rate of complete viral suppression at 1 year was 94.7%, 94.7% and 96.1% in ETV, TDF and TAF groups, respectively (p = 0.877). A significant proportion of patients developed renal dysfunction during chemotherapy. The incidences of acute kidney injury (AKI) and chronic kidney disease stage migration were comparable among the ETV, TDF and TAF groups. TAF was relatively safe in patients with predisposing factors of AKI, including hypoalbuminemia and cisplatin use. In patients who were switched from TDF to TAF during chemotherapy, the renal function remained stable and viral suppression was well maintained after switching. In conclusion, TAF had good renal safety and comparable efficacy with ETV and TDF for HBV-infected cancer patients receiving chemotherapy. Switching from TDF to TAF during chemotherapy is safe, without a loss of efficacy.

RESUMO

BACKGROUND: Although the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-PAN26 is widely used to assess health-related quality of life (HRQoL), its group-level minimal important difference (MID) and individual-level responder definition (RD) are not established; we calculated MID and RD using HRQoL data from the APACT trial in patients with surgically resected pancreatic cancer who received adjuvant chemotherapy. METHODS: HRQoL was assessed using EORTC QLQ-C30 and QLQ-PAN26 at baseline, during treatment, at end of treatment, and during follow-up. Distribution-based MIDs were estimated using 0.5 × baseline standard deviation (SD) and reliability-based (intraclass correlation) standard error of measurement (SEM). Anchor-based MIDs and RDs (anchor, QLQ-C30 overall health) were estimated using a linear mixed model. RESULTS: Overall, 772 patients completed the baseline assessment. Distribution-based MIDs (0.5 × SD) for QLQ-PAN26 scales ranged from 12 to 13, except hepatic symptoms (≈8), pancreatic pain (≈10), and sexual dysfunction (≈17); those for stand-alone items ranged from 12 to 16. The SEM values were similar. Among scales/items sufficiently correlated (r > 0.30) with the anchor, MIDs ranged from 5 to 9. Within-patient QLQ-PAN26 RD estimates varied by direction (deterioration vs. improvement) and scale/item, but all values were lower than the true possible within-patient change (e.g. 16.7 points for a two-item scale) given a one-category change on the raw scale. CONCLUSIONS: Compared with distribution-based MIDs, anchor-based MIDs were twice as sensitive in detecting group-level changes in QLQ-PAN26 scales/items. For interpreting clinically meaningful change, RDs cannot be less than the true minimum of the scale. The group-level MID may help clinicians/researchers interpret HRQoL changes.

RESUMO

The global, randomized NAPOLI-1 phase 3 trial reported a survival benefit with liposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (nal-IRI+5-FU/LV) in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) after previous gemcitabine-based therapy. Median overall survival (OS) with nal-IRI+5-FU/LV was 6.1 vs 4.2 months with 5-FU/LV alone (unstratified hazard ratio [HR] = 0.67, P = .012). Herein, we report efficacy and safety results from a post-hoc subgroup analysis of Asian patients treated at Asian centers. Primary study endpoint was OS; secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. Patients receiving nal-IRI+5-FU/LV (n = 34) had significantly longer median OS versus 5-FU/LV (n = 35) (8.9 vs 3.7 months; unstratified HR = 0.51, P = .025). Patients had significantly increased median PFS with nal-IRI+5-FU/LV versus 5-FU/LV (4.0 vs 1.4; unstratified HR = 0.48, P = .011), and increased ORR (8.8% vs 0; P = .114). nal-IRI monotherapy (n = 50) numerically improved efficacy endpoints versus 5-FU/LV (n = 48): median OS was 5.8 versus 4.3 months (HR = 0.83, P = .423) and median PFS was 2.8 versus 1.4 months (HR = 0.69, P = .155). Grade ≥3 neutropenia was reported more frequently with nal-IRI+5-FU/LV versus 5-FU/LV (54.5% vs 3.4%), and incidence of grade ≥3 diarrhea was comparable between the two arms (3.0% vs 6.9%). This subgroup analysis confirms nal-IRI+5-FU/LV as an efficacious treatment option that improves survival in Asian patients with mPDAC that progressed after gemcitabine-based therapy, with a safety profile agreeing with previous findings. The nal-IRI+5-FU/LV regimen should represent a new standard of care for these patients in Asia. (Clinicaltrials.gov: NCT01494506).

RESUMO

BACKGROUND: Obesity and metabolic diseases including diabetes, hyperlipidemia, and hypertension are reportedly associated with an increased risk of psoriasis. However, few prospective studies have investigated the association of obesity and metabolic diseases with the risk of psoriasis. OBJECTIVE: To examine whether obesity or metabolic diseases increase the risk of psoriasis. METHODS: Participants were collected from 4 rounds (2001, 2005, 2009, and 2013) of the Taiwan National Health Interview Survey. Incident cases of psoriasis were identified from the National Health Insurance database. Participants were followed from the time of the National Health Interview Survey interview until December 31, 2017, or until a diagnosis of psoriasis was made or the participant died. The Cox regression model was used for the analyses. RESULTS: Of 60,136 participants, 406 developed psoriasis during 649,506 person-years of follow-up. Compared to participants with a BMI of 18.5-22.9, the adjusted hazard ratios (aHR) of psoriasis were 1.34 (95% CI 1.05-1.71) for a BMI of 25.0-29.9 and 2.70 (95% CI 1.95-3.72) for a BMI ≥30. Neither individual nor multiple metabolic diseases were associated with incident psoriasis. Participants with a BMI ≥30 were at significantly higher risk of both psoriasis without arthritis (aHR 2.60; 95% CI 1.85-3.67) and psoriatic arthritis (aHR 3.96; 95% CI 1.45-10.82). CONCLUSION: Obesity, but not metabolic diseases, significantly increased the risk of psoriasis.

RESUMO

BACKGROUND: Duodenal obstruction is uncommon in patients with pancreatic cancer. However, the obstruction rate is increasing as a result of advancements in chemotherapy and target therapy. This study aimed to investigate the effect of self-expandable metal stent placement on outcomes of patients with duodenal obstruction secondary to pancreatic carcinoma. METHODS: Twenty-nine consecutive inoperable patients with pancreatic cancer and gastric outlet obstruction who received metallic stent placement in our hospital between September 2009 and October 2017 were enrolled for analysis. RESULTS: Fifteen male patients and 14 female patients receiving stent placement with a median age of 68 years (range, 50-85 years) were included. The technical and clinical success rates of the procedure were 100% and 89.7%, respectively. The Gastric Outlet Obstruction Scoring System scores were significantly improved at day 1 (1.14 ± 0.51) and days 7 (2.21 ± 0.9) after the implantation compared to those prior to the procedure (0.38 ± 0.49) (p < 0.001). Aspiration pneumonia and bleeding developed in 1 patient (3.4%) after the procedure. Stent dysfunction developed in 6 of 29 patients (20.6%). The median stent patency time was 109 days (range, 10-314 days). The median survival time was 114 days (range, 15-323 days). Post-stent chemotherapy predicted better survival (hazard ratio: 0.2, 95% confidence interval: 0.08-0.51, p = 0.001). CONCLUSION: Metallic stent placement is an effective treatment for patients with inoperable pancreatic cancer leading to gastric outlet obstruction. Chemotherapy may be considered following stent placement.

RESUMO

BACKGROUND & AIMS: Transarterial chemoembolization (TACE) is a standard treatment for Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC), but the outcome varied. This study aimed to develop a model to predict the outcome of TACE in HCC patients. METHODS: Consecutive 570 treatment-naïve BCLC stage B HCC patients undergoing TACE as the initial treatment from 2007 to 2016 were retrospectively enrolled. Factors associated with survival were analysed. Patients undergoing TACE from 2007 to 2011 constituted the training cohort (n = 293), while patients undergoing TACE from 2012 to 2016 constituted the validation cohort (n = 277). Homogeneity and corrected Akaike information criterion (AICc) were compared between each prognostic model. RESULTS: A total of 1796 TACE sessions were performed for the 570 patients during the median follow-up period of 18.3 months. By multivariate analysis, beyond up-to-11 criteria (hazard ratio [HR] = 1.694, P < .001), alpha-foetoprotein >200 ng/mL (HR = 1.771, P < .001) and albumin-bilirubin (ALBI) grade 2 or 3 (HR = 1.817, P < .001) were independent predictors of overall survival (OS) in the training cohort. An ALBI-TAE model based on the three independent predictors of OS from the training cohort was developed to classify HCC patients into four subgroups. The performance of the ALBI-TAE model was superior to other prognostic models with lowest AICc values and highest homogeneity in both the training and validation datasets as well as the overall cohort. CONCLUSIONS: Albumin-bilirubin grade is an important factor associated with survival in BCLC stage B HCC patients undergoing TACE. ALBI-TAE model can be applied to select patients who can get most benefit from TACE.

RESUMO

BACKGROUND: Alcohol consumption and smoking have long been suspected of increasing the risk of developing psoriasis. Most evidence to date has derived from cross-sectional or case-control studies. OBJECTIVE: We sought to investigate the effects of alcohol and smoking on incident psoriasis. METHODS: Alcohol consumption, smoking status, and other covariates were collected from four rounds (2001, 2005, 2009, and 2013) of the Taiwan National Health Interview Survey. Incident psoriasis was identified from the National Health Insurance database. Cox regression model was used for the analysis. RESULTS: Of 60,136 subjects, 242 (0.40%) developed psoriasis. After controlling for demographics and comorbidities, alcohol consumption was not significantly associated with psoriasis risk. Conversely, psoriasis risk was higher for current smokers than never smokers (adjusted hazard ratio 1.47 [95% confidence interval 1.04-2.07]). The risks were higher among subjects who smoked >25 cigarettes per day and for >20 pack-years. In subgroup analysis, current smoking was significantly associated with risk of psoriasis without psoriatic arthritis but not psoriatic arthritis alone. LIMITATIONS: Alcohol consumption was not assessed based on the number of drinks consumed. CONCLUSION: Current smoking increased the risk of psoriasis, particularly augmented for individuals who smoked >25 cigarettes per day and for >20 pack-years, while alcohol consumption was not significantly associated with psoriasis development.

RESUMO

Napabucasin (also known as BBI-608 or BBI608) is an investigational, oral agent hypothesized to inhibit multiple oncogenic pathways. In this article, we describe the design and rationale for the CanStem111P clinical trial, a multicenter, randomized, open-label, Phase III study designed to determine the efficacy and safety of combining napabucasin with nab-paclitaxel and gemcitabine for first-line treatment of patients with metastatic pancreatic adenocarcinoma (NCT02993731). Patients were randomized in a 1:1 fashion to receive weekly gemcitabine and nab-paclitaxel with or without napabucasin. The results of this study will help define the role of this novel agent in the management of advanced pancreatic cancer.

RESUMO

BACKGROUND: Post-hoc analyses of AFP response and progression and their relationship with objective measures of response and survival were performed in patients from REACH. METHODS: Serum AFP was measured at baseline and every 3 cycles (2 weeks/cycle). Associations between AFP and radiographic progression and efficacy end points were analysed. RESULTS: Median percent AFP increase from baseline was smaller in the ramucirumab than in the placebo arm throughout treatment. Time to AFP progression (HR 0.621; P < 0.0001) and to radiographic progression (HR 0.613; P < 0.0001) favoured ramucirumab. Association between AFP and radiographic progression was shown at 6 (OR 6.44, 95% CI 4.03, 10.29; P < 0.0001) and 12 weeks (OR 2.28, 95% CI 1.47, 3.53; P = 0.0002). AFP response was higher with ramucirumab compared with placebo (P < 0.0001). More patients in the ramucirumab arm experienced tumour shrinkage and AFP response compared with placebo. Survival was longer in patients with AFP response (13.6 months) than in patients without (6.2 months), irrespective of treatment (HR 0.457, P < 0.0001). CONCLUSIONS: Treatment with ramucirumab prolonged time to AFP progression, slowed AFP increase and was more likely to induce AFP response. Similar benefits in radiographic progression and response correlated with AFP changes.

RESUMO

The risk of renal events in HBsAg-positive cancer patients receiving tenofovir disoproxil fumarate (TDF) or entecavir (ETV) antiviral prophylaxis during chemotherapy has not been evaluated. This study aimed to evaluate the renal safety of TDF and ETV during chemotherapy. Consecutive, 219 HBsAg-positive cancer patients treated with TDF (n = 106) or ETV (n = 113) for antiviral prophylaxis during chemotherapy with baseline serum creatinine (SCr) <1.2 mg/dL were retrospectively enrolled. Serial SCr levels and estimated glomerular filtration rate (eGFR) were monitored. The incidence of acute kidney injury (AKI) during antiviral prophylaxis was 33% and 38.9% in TDF and ETV groups, respectively (P = 0.441), while the incidence of sustained kidney injury was 11.3% and 11.5%, respectively (P = 1.000). By multivariate analysis, diuretics use (hazard ratio (HR) = 2.011, P = 0.042) and serum albumin levels (HR = 0.441, P = 0.001) were independent predictors of AKI; serum albumin levels (HR = 0.252, P = 0.002) was the only factor associated with sustained kidney injury; age (HR = 2.752, P < 0.001), baseline SCr levels (HR = 3.386, P < 0.001), and serum albumin levels (HR = 0.437, P = 0.001) were factors associated with a new eGFR <60 mL/min. 34.9% of patients in TDF group and 35.4% in ETV group had deteriorated chronic kidney disease (CKD) stage at the end of follow-up, respectively. There were no significant differences in the risk of renal events or CKD stage migration between TDF and ETV groups. Renal events may develop in about one-third of HBsAg-positive cancer patients undergoing chemotherapy. The risk of renal function impairment was comparable between patients treated with TDF and ETV antiviral prophylaxis.

RESUMO

Background Ruxolitinib, a Janus kinase 1 (JAK1)/JAK2 inhibitor, plus capecitabine improved overall survival (OS) vs capecitabine in a subgroup analysis of patients with metastatic pancreatic cancer and systemic inflammation (C-reactive protein [CRP] >13 mg/dL) in the randomized phase II RECAP study. We report results from two randomized phase III studies, JANUS 1 (NCT02117479) and JANUS 2 (NCT02119663). Patients and Methods Adults with advanced/metastatic pancreatic cancer, one prior chemotherapy regimen and CRP >10 mg/L were randomized 1:1 (stratified by modified Glasgow Prognostic Score [1 vs 2] and Eastern Cooperative Oncology Group performance status [0/1 vs 2]) to 21-day cycles of ruxolitinib 15 mg twice daily plus capecitabine 2000 mg/m2/day (Days 1-14) or placebo plus capecitabine. The primary endpoint was OS. Results Both studies were terminated following a planned interim futility/efficacy analysis of JANUS 1. Overall, 321 and 86 patients were randomized in JANUS 1 (ruxolitinib: n = 161; placebo: n = 160) and JANUS 2 (ruxolitinib: n = 43; placebo: n = 43). There was no significant difference in OS or progression-free survival (PFS) between treatments in JANUS 1 (OS: hazard ratio [HR], 0.969, 95% confidence interval [CI], 0.747-1.256; PFS: HR, 1.056; 95% CI, 0.827-1.348) or JANUS 2 (OS: HR, 1.584; 95% CI, 0.886-2.830; PFS: HR, 1.166; 95% CI, 0.687-1.978). The most common hematologic adverse event was anemia. No new safety signals with ruxolitinib or capecitabine were identified. Conclusions Ruxolitinib plus capecitabine was well tolerated in refractory pancreatic cancer patients; this combination did not improve survival.

RESUMO

BACKGROUND & AIMS: Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC) but is challenging after treatment failure. Appropriate criteria for enrolling patients into second-line trials are still limited. In this study, we aimed to establish more objective criteria based on Albumin-Bilirubin (ALBI) grade to select patients with better post-progression survival (PPS) for second-line treatment. METHODS: Consecutive 404 advanced HCC patients receiving sorafenib were retrospectively enrolled. All patients were in Child-Pugh class A and BCLC stage C with either portal vein invasion or extrahepatic metastasis at the beginning of sorafenib treatment. Radiological evaluation based on mRECIST criteria and clinical assessments with compliance were performed on schedule. RESULTS: During the median follow-up period of 5.8 months, 310 patients developed progressive disease (PD) and 350 deaths occurred. The PD patients were randomized into derivation and validation cohorts by a 1:1 ratio. The independent predictors of poor PPS in derivation cohort were ALBI grade 3 at PD (hazard ratio [HR]=3.24, P = .002), new extrahepatic lesions (NEH) (HR=1.75, P = .011), and early PD within 4 months (HR=1.88, P = .037). ALBI-PD criteria were proposed by incorporating these three risk factors. In the validation cohort, PPS could be independently predicted by presence of early PD, NEH as well as ALBI grade 3 at PD. Patients within ALBI-PD criteria had significant longer median PPS than those beyond it even in Child-Pugh A (9.7 vs 4.9 months, P = .005) subpopulations. CONCLUSIONS: The ALBI-PD criteria can differentiate PPS and stratify the patients with advanced HCC for the second-line trials or salvage therapy.

RESUMO

To investigate the association between serum albumin levels and cause-specific mortality among community-dwelling older adults. This cohort study was based on data obtained from the government-sponsored Annual Geriatric Health Examination Program for the older adults in Taipei City between 2006 and 2010. The study sample consisted of 77,531 community-dwelling Taipei citizens (≥65 years old). Mortality was determined by matching the participants' medical records with national death files. Serum albumin levels were categorized into <3.6, 3.6-3.7, 3.8-3.9, 4.0-4.1, 4.2-4.3, and ≥4.4 g/dL. Cox proportional hazards regression models were used to evaluate the association between albumin levels and cause-specific mortality. Spline regression was used to calculate the risk of mortality associated with albumin levels, modeled as continuous variables. Community-dwelling older adults had a mean albumin level of 4.3 g/dL, which significantly reduced by age. Compared to albumin levels ≥4.4 g/dL, mildly low albumin levels (4.2-4.3 g/dL) were associated with an increased mortality risk (hazard ratio [HR]: 1.16, 95% confidence interval [CI]: 1.05-1.28 for all-cause mortality), and albumin levels <4.2 g/dL were associated with significantly higher rates of all-cause, cancer, cardiovascular, and respiratory mortalities. In the spline regression, the curve of mortality risk was relatively flat at an albumin level ≥4.4 g/dL, and the mortality risk gradually increased as the albumin level declined. Albumin levels ≥4.4 g/dL were associated with better survival among community-dwelling older adults, and mortality risk increased as the albumin level decreased.

RESUMO

The X protein of hepatitis B virus (HBx) has been specifically implicated in the development of hepatocellular carcinoma (HCC). Clinical associations of HBx isoforms with chronic hepatitis and HCC have not been well studied. HBx has two roles in liver cells, namely pro-apoptotic and anti-apoptotic. In this report, we examined the role of Ser31-HBx in HCC and chronic hepatitis. Using the case-control study, we determined risks of chronic hepatitis and HCC conferred by hepatitis B virus (HBV) containing Ser31-HBx that was phosphorylated by Akt. Ser31-HBx isoforms conferred 3.23-fold risk of HCC in male and 3.36-fold risk in female. Ser31 isoforms were associated with 3.12-fold risk of chronic hepatitis and 3.43-fold risk of cirrhosis and also associated with higher HBV viral load and replication efficiency and lower rate of HBe loss. To determine the mechanism, we found that Ser31-HBx constituted an oncogenic circuit with Akt and cooperated with ras to transform NIH3T3 cells in contrast to non-Ser31-HBxs that did not transduce oncogenic signals. Our results give a clue to account for an underlying cause of HBx-mediated hepatocarcinogenesis. It appears that Ser31 phosphorylation of HBx by Akt plays an important role. The current study provides an example of association of HBV genome variations with risks of HCC and chronic hepatitis.

RESUMO

BACKGROUND: Nanoliposomal irinotecan showed activity in a phase 2 study in patients with metastatic pancreatic ductal adenocarcinoma previously treated with gemcitabine-based therapies. We assessed the effect of nanoliposomal irinotecan alone or combined with fluorouracil and folinic acid in a phase 3 trial in this population. METHODS: We did a global, phase 3, randomised, open-label trial at 76 sites in 14 countries. Eligible patients with metastatic pancreatic ductal adenocarcinoma previously treated with gemcitabine-based therapy were randomly assigned (1:1) using an interactive web response system at a central location to receive either nanoliposomal irinotecan monotherapy (120 mg/m(2) every 3 weeks, equivalent to 100 mg/m(2) of irinotecan base) or fluorouracil and folinic acid. A third arm consisting of nanoliposomal irinotecan (80 mg/m(2), equivalent to 70 mg/m(2) of irinotecan base) with fluorouracil and folinic acid every 2 weeks was added later (1:1:1), in a protocol amendment. Randomisation was stratified by baseline albumin, Karnofsky performance status, and ethnic origin. Treatment was continued until disease progression or intolerable toxic effects. The primary endpoint was overall survival, assessed in the intention-to-treat population. The primary analysis was planned after 305 events. Safety was assessed in all patients who had received study drug. This trial is registered at ClinicalTrials.gov, number NCT01494506. FINDINGS: Between Jan 11, 2012, and Sept 11, 2013, 417 patients were randomly assigned either nanoliposomal irinotecan plus fluorouracil and folinic acid (n=117), nanoliposomal irinotecan monotherapy (n=151), or fluorouracil and folinic acid (n=149). After 313 events, median overall survival in patients assigned nanoliposomal irinotecan plus fluorouracil and folinic acid was 6.1 months (95% CI 4.8-8.9) vs 4.2 months (3.3-5.3) with fluorouracil and folinic acid (hazard ratio 0.67, 95% CI 0.49-0.92; p=0.012). Median overall survival did not differ between patients assigned nanoliposomal irinotecan monotherapy and those allocated fluorouracil and folinic acid (4.9 months [4.2-5.6] vs 4.2 months [3.6-4.9]; 0.99, 0.77-1.28; p=0.94). The grade 3 or 4 adverse events that occurred most frequently in the 117 patients assigned nanoliposomal irinotecan plus fluorouracil and folinic acid were neutropenia (32 [27%]), diarrhoea (15 [13%]), vomiting (13 [11%]), and fatigue (16 [14%]). INTERPRETATION: Nanoliposomal irinotecan in combination with fluorouracil and folinic acid extends survival with a manageable safety profile in patients with metastatic pancreatic ductal adenocarcinoma who previously received gemcitabine-based therapy. This agent represents a new treatment option for this population. FUNDING: Merrimack Pharmaceuticals.
