RESUMEN
This study aimed to compare second-line treatment outcomes for patients with unresectable pancreatic cancer previously treated with gemcitabine plus nab-paclitaxel (GnP) therapy. We conducted an integrated analysis of two retrospective studies included 318 patients receiving nanoliposomal irinotecan + 5-fluorouracil/folinic acid (NFF) (n = 102), S-1 (n = 57), or FOLFIRINOX (n = 14) as second-line treatment. Median overall survival (OS) in the NFF group was 9.08 months, significantly better than S-1 (4.90 months, P = 0.002). FOLFIRINOX had a median OS of 4.77 months, not statistically different from NFF. Subgroup analyses of OS indicated NFF was generally superior, however, a statistical interaction was observed between the treatment regimen in serum Alb < 3.5 g/dL (P = 0.042) and serum CRP ≥ 0.3 mg/dL (P = 0.006). Median progression-free survival (PFS) was 2.93 months for NFF, significantly better than S-1 (2.53 months, P = 0.024), while FOLFIRINOX had a comparable PFS (3.04 months, P = 0.948). Multivariate analysis identified the serum CRP, serum CA19-9, duration of first-line GnP therapy, and use (yes/no) of S-1 for second-line treatment as independent predictors for OS. This study concludes that second-line NFF therapy demonstrated a more favorable OS compared to S-1 therapy, however, it is still important to consider the patient background characteristics while selecting the most appropriate treatment.

First-line chemotherapy for patients with metastatic pancreatic cancer (MPC) includes gemcitabine plus nab-paclitaxel (GnP) and FOLFIRINOX (FFX). However, the efficacy of second-line chemotherapy and the role of combination chemotherapy in clinical practice is still unknown. Data was gathered from 14 hospitals in the Kyushu area of Japan from December 2013 to March 2017. The median overall survival (mOS) from second-line treatment was contrasted between patients who received second-line chemotherapy (CT group) and those who received the best supportive care (BSC group). Furthermore, the mOS of combination chemotherapy was compared to mono chemotherapy in the CT group. To control possible bias in the selection of treatment, we performed a propensity score-adjusted analysis. A total of 255 patients received GnP or FFX as first-line chemotherapy. There were 156 in the CT group and 77 in the BSC group of these. The CT group had a significantly longer mOS than the BSC group (5.2 vs. 2.6 months; adjusted hazard ratio (HR) 0.38; 95% CI 0.27-0.54). In the CT group, 89 patients received combination chemotherapy while 67 received mono chemotherapy. The mOS did not differ significantly between the combination and mono chemotherapy groups (5.5 vs. 4.8 months; adjusted HR 0.88; 95% CI 0.58-1.33). Among patients with MPC receiving second-line treatment, the CT group had a significantly longer mOS than the BSC group, but combination chemotherapy conferred no improvement in survival compared to mono chemotherapy.

BACKGROUND: Patients with metastatic pancreatic cancer refractory to first-line chemotherapy (CTx) have few treatment options. It is unclear what kind of patients could be brought about survival benefit by 2nd-line CTx after refractory to gemcitabine + nab-PTX (GnP) or FOLFIRINOX. METHODS: This analysis was conducted as part of a multicenter retrospective study of GnP or FOLFIRINOX in patients with metastatic pancreatic cancer. Excluding censored cases, 156 and 77 patients, respectively, received second-line chemotherapy (CTx) and best supportive care (BSC). Using prognostic factors for post-discontinuation survivals (PDSs) at the first-line determination in multivariate analysis, we developed a scoring system to demonstrate the benefit of second-line CTx. RESULTS: The second-line CTx group had a median PDS of 5.2 months, whereas the BSC group had a median PDS of 2.7 months (hazard ratio 0.42; 95% confidence interval [CI] 0.31-0.57; p < 0.01). According to the Cox regression model, serum albumin levels below 3.5 g/dL, and CA19-9 levels above 1000 U/mL were independent prognostic factors (p < 0.01). Serum albumin (≥ and < 3.5 g/dL allotted to scores 0 and 1) and CA19-9 (< and ≥ 1000 U/mL allotted to scores 0 and 1) at first-line determination were used to develop the scoring system. The PDSs of patients with scores of 0 and 1 were significantly better than those of the BSC group; however, there was no significant difference between the PDSs of patients with score 2 and the BSC group. CONCLUSION: The survival advantage of second-line CTx, was observed in patients with scores of 0 and 1 but not in those with score 2.

There are limited absolute biomarkers for determining the prognosis before first- and second-line palliative chemotherapy in unresectable pancreatic cancer (urPC) patients. To find the best prognostic inflammatory marker, we investigated relationships between overall survival (OS) and six inflammatory markers; C-reactive protein/albumin ratio (CAR), neutrophil-lymphocyte ratio (NLR), prognostic nutrition index (PNI), platelet-lymphocyte ratio (PLR), Glasgow prognostic score (GPS), and prognostic index (PI). We examined 255 patients who received gemcitabine + nab-paclitaxel or FOLFIRINOX as first-line chemotherapy and 159 patients who subsequently underwent second-line chemotherapy. First-line patients with lower CAR had better OS compared to those with a higher CAR (hazard ratio 0.57; 95% confidential index 0.42-77; P < 0.01). Similarly, lower NLR (P = 0.01), higher PNI (P = 0.04), lower PLR (P = 0.03), GPS score of 0 (P < 0.01) and PI score of 0 (P < 0.01) were all associated with better OS. CAR demonstrated the best superiority for determining survival prognosis through the use of area under the curve of time-dependent receiver-operating characteristic curves. Furthermore, a lower CAR before second-line therapy exhibited better OS versus higher CAR (P < 0.01). Therefore, CAR might be a useful biomarker for predicting urPC patient prognosis in both first- and second-line chemotherapy.

BACKGROUND/AIM: Recent advances in chemotherapy have made significant progress in conversion surgery (CS) for unresectable pancreatic cancer (uPC). However, the success rate and efficacy of CS have not been fully demonstrated in patients with uPC treated with FOLFIRINOX (FFX) or gemcitabine plus nab-paclitaxel (GnP). PATIENTS AND METHODS: We retrospectively reviewed the records of 318 patients with uPC who received FFX or GnP as first-line chemotherapy. The efficacy in the CS group, defined as undergoing complete resection after chemotherapy, was analyzed, and compared with the non-CS group; then, contributing factors to achieving CS were extracted. We also analyzed differences in the efficacy of CS between locally advanced pancreatic cancer (LAPC) and metastatic pancreatic cancer (MPC). RESULTS: Overall, CS was achieved in 4.3% of cases, eight patients (13.3%) with LAPC and five (2.1%) with MPC. Contributing factors to CS were LAPC, no liver metastasis, CA19-9 ≤37, and chemotherapy response. After adjusting for these, overall survival was significantly better in the CS group than in the non-CS group [median of 32.9 vs. 11.3 months; adjusted hazard ratio (HR)=0.32; 95% confidence interval (CI)=0.14-0.70; p<0.01]. Median relapse-free survival duration after CS was 19.1 and 18.1 months in the LAPC-CS and MPC-CS group, respectively (p=0.84). The median post-conversion survival was 27.6 months in the entire CS group, 43.8 months in the LAPC-CS group and 21.3 months in the MPC-CS group. CONCLUSION: CS was achieved in 13.3% of LAPC and 2.1% of MPC cases. If possible, CS can markedly improve prognosis, even in MPC.

INTRODUCTION: Original FOLFIRINOX (oFFX) is more toxic than other regimens for patients with metastatic pancreatic cancer (mPC); therefore, a modified FFX (mFFX) regimen with a reduced dosage has been used in Japanese clinical practice. However, very few studies have compared these two regimens. METHODS: This study was conducted as part of a multicenter retrospective study of 318 patients with mPC across 14 centers in Japan (NAPOLEON study). To control for potential bias and confounders, we conducted a propensity score-adjusted analysis of patient characteristics and clinical outcomes. RESULTS: oFFX and mFFX were administered to 48 and 54 patients. More patients with younger age and poorer performance status were included in the oFFX group. The overall survival (OS; median, 11.6 vs. 11.3 months; hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.60-1.40; p = 0.67), progression-free survival (PFS) (median, 6.3 vs. 5.7 months; HR, 0.85; 95% CI, 0.56-1.28; p = 0.44), and overall response rate (29 vs. 26%, p = 0.71) were not significantly different for the oFFX and mFFX groups. Thrombopenia and liver dysfunction were significantly more frequent with oFFX than with mFFX. The median received dose intensity of CPT-11 was higher with oFFX than with mFFX (299 vs. 270 mg/m2/week, p < 0.01). The propensity score-adjusted analysis revealed no statistically significant differences in OS and PFS between the two groups. CONCLUSION: In our data, there was no significant difference in efficacy between mFFX and oFFX, and mFFX has fewer adverse events.

Improvements in the hepatocellular carcinoma (HCC) recurrence rate and survival have been frequently reported following virus eradication after hepatitis C virus (HCV)-related HCC cure. However, the efficacy of direct-acting antiviral (DAA) therapy in patients who included those with advanced HCC and decreased hepatic functional reserve is unknown. A comparative examination was retrospectively conducted of 141 patients with hepatitis C who started DAA therapy within 1 year after undergoing curative HCC treatment and showed a sustained viral response (SVR) and 327 patients who underwent curative treatment for HCV-related HCC and did not subsequently receive antiviral therapy. Whether DAA therapy was given was identified as an independent factor related to both HCC recurrence and survival. Both the recurrence and survival rates improved significantly with DAA therapy in Child-Pugh (CP)-A, whereas no difference in the recurrence rate was seen with DAA therapy in CP-B. However, the survival rate was significantly higher in the DAA group in this class. Similarly, dividing the patients by the Milan criteria showed significant improvements in the recurrence rate and survival with DAA therapy in patients within the Milan criteria. Patients with HCC beyond the Milan criteria showed no difference in recurrence rates, but the DAA group tended to have higher survival rates. Thus, DAA after curative therapy for HCC can be expected to improve survival in patients with advanced HCC or decreased hepatic functional reserve. HCV should be aggressively eradicated in all patients eligible for curative treatment of HCC.

BACKGROUND: No reliable nomogram has been developed until date for predicting the survival in patients with unresectable pancreatic cancer undergoing treatment with gemcitabine plus nab-paclitaxel (GnP) or FOLFIRINOX. METHODS: This analysis was conducted using clinical data of Japanese patients with unresectable pancreatic cancer undergoing GnP or FOLFIRINOX treatment obtained from a multicenter study (NAPOLEON study). A Cox proportional hazards model was used to identify the independent prognostic factors. A nomogram to predict 6-, 12-, and 18-month survival probabilities was generated, validated by using the concordance index (C-index), and calibrated by the bootstrapping method. And then, we attempted risk stratification for survival by classifying the patients according to the sum of the scores on the nomogram (total nomogram points). RESULTS: A total of 318 patients were enrolled. A prognostic nomogram was generated using data on the Eastern Cooperative Oncology Group performance status, liver metastasis, serum LDH, serum CRP, and serum CA19-9. The C-indexes of the nomogram were 0.77, 0.72 and 0.70 for 6-, 12-, and 18-month survival, respectively. The calibration plot showed optimal agreement at all points. Risk stratification based on tertiles of the total nomogram points yielded clear separations of the survival curves. The median survival times in the low-, moderate-, and high-risk groups were 15.8, 12.8 and 7.8 months (P<0.05), respectively. CONCLUSIONS: Our nomogram might be a convenient and inexpensive tool to accurately predict survival in Japanese patients with unresectable pancreatic cancer undergoing treatment with GnP or FOLFIRINOX, and will help clinicians in selecting appropriate therapeutic strategies for individualized management.

OBJECTIVES: This study aimed to examine the efficacy and safety of gemcitabine plus nab-paclitaxel (GnP) in older patients with metastatic pancreatic cancer (MPC), especially those ≥75 years old. MATERIALS AND METHODS: This study retrospectively enrolled 153 patients with MPC who received GnP as first-line chemotherapy. Patients ≥75 years old were allocated to the older group, and those <75 years old were assigned to the non-older group. We compared safety, antitumor efficacy, and survival between the two groups. In the older group, prognostic indicators of survival were also assessed. RESULTS: The pretreatment characteristics of the two groups were not significantly different excluding age, history of malignancy, and C-reactive protein levels. The initial dose and relative dose intensities of GnP were significantly lower in the older group. There were no significant differences in the adverse event and antitumor response rates between the two groups. Median progression-free survival and overall survival were 5.5 and 12.0 months, respectively, in the older group, versus 6.0 and 11.1 months, respectively, in the non-older group. In the older group, a Geriatric Nutrition Risk Index (GNRI) of less than 86 was associated with poor prognosis. CONCLUSION: GnP exhibited acceptable efficacy and safety in patients ≥75 years old with MPC. GNRI might be helpful for identifying older individuals at higher risk of unfavorable outcomes.

OBJECTIVES: FOLFIRINOX (FFX, a combination of oxaliplatin, irinotecan, fluorouracil, and leucovorin) and gemcitabine plus nab-paclitaxel (GnP) have been used as standard, first-line treatments for advanced pancreatic cancer. However, no study has compared the efficacy of the 2 regimens. This study retrospectively compared the efficacy and safety of the 2 regimens in patients with locally advanced pancreatic cancer. METHODS: We reviewed the records of patients with locally advanced pancreatic cancer who started FFX or GnP as first-line chemotherapy as part of a multicenter retrospective study in patients with unresectable pancreatic cancer treated with FFX or GnP (NAPOLEON study). RESULTS: Sixteen of the 63 patients were treated with FFX, and the other 47 patients were treated with GnP between December 2013 and March 2017. There were no significant differences in median overall survival rate between the GnP (15.5 months) and FFX (14.3 months, P = 0.60) groups or median progression-free survival rate between the GnP (8.8 months) and FFX (8.1 months, P = 0.51) groups. Both treatments were generally well tolerated, although anorexia was more severe in the FFX group than in the GnP group. CONCLUSIONS: The effects of FFX and GnP were similar but resulted in different toxicities, which could guide agent choice.

BACKGROUND/AIM: The aim of the study was to evaluate gemcitabine plus nanoparticle albumin-bound paclitaxel (GnP) and FOLFIRINOX for recurrent pancreatic cancer (rPC) after resection. PATIENTS AND METHODS: Forty-four patients with rPC and 211 with de novo metastatic pancreatic cancer (mPC) who received GnP or FOLFIRINOX as first-line chemotherapy were retrospectively analyzed. RESULTS: On crude analysis, the median overall survival (OS) was significantly longer in the rPC group than in the mPC group (14.0 vs. 10.6 months, respectively; p=0.02). However, the difference was not significant on adjusted analysis using the Cox proportional hazards model (adjusted p=0.90). Patients receiving FOLFIRINOX (n=10) and GnP (n=34) in the rPC group had comparable OS (medians, 12.2 vs. 14.4 months, respectively; p=0.82) even after adjusting for covariates using the Cox model (adjusted p=0.18). CONCLUSION: The outcomes of patients in the rPC and mPC groups were comparable following chemotherapy. Both FOLFIRINOX and GnP may be reasonable options for treating rPC.

The real-world virological efficacy and safety of interferon-free direct-acting antiviral (DAA) therapy with sofosbuvir (SOF) and velpatasvir (VEL) were assessed in hepatitis C virus (HCV) genotype 1- and 2-infected patients with decompensated cirrhosis. A total of 65 patients with HCV-related decompensated cirrhosis (Child-Pugh score of 7 points or more) who were treated with the SOF/VEL regimen were enrolled. The sustained virological response (SVR) rate and safety profile were analyzed. SVR was defined as undetectable serum HCV RNA at 12 weeks after the end of treatment (SVR12). The percentages of patients with undetectable HCV RNA at 4, 8, and 12 weeks after the start of therapy were 81.2% (95% confidence interval [CI], 69.5-89.9) (52/64), 98.4% (95% CI, 91.2-100.0) (60/61), and 98.5% (95% CI, 91.7-100.0) (64/65), respectively. The overall SVR rate was 92.3% (95% CI, 83.0-97.5) (60/65). Albumin-bilirubin (ALBI) scores decreased during and after treatment (p < 0.001), and there were significant differences between baseline and end of treatment and between baseline and SVR12. Subgroup analyses showed no significant differences in SVR rates according to patient age, sex, HCV genotype (subtype), Child-Pugh classification, modified ALBI grade, presence of ascites, presence of hepatic coma, or history of hepatocellular carcinoma. In all subpopulations, the SVR rates were higher than 80%. There were no severe adverse events associated with the treatment. The SOF/VEL regimen showed good virological efficacy and acceptable safety even in patients with HCV-related decompensated cirrhosis.

BACKGROUND: Lenvatinib (LEN) has been approved for patients with unresectable hepatocellular carcinoma (u-HCC) since March 2018 in Japan. We performed a retrospective nationwide multicenter study to clarify the clinical characteristics of LEN in real-world practice. METHODS: A total of 343 u-HCC patients who received LEN from March 2018 to May 2020 at 23 sites in Japan were registered. RESULTS: During the median observation period of 10.5 months, 143 patients died. In Child-Pugh A (n = 276) and Child-Pugh B (n = 67) patients, the median overall survival (OS) was 21.0 and 9.0 months. The median progression-free survival (PFS) was 8.8 months in Child-Pugh A patients. The objective response rate (ORR) and disease control rate (DCR) according to modified response evaluation criteria in solid tumors (RECIST criteria) were 42.1% and 82.1%. The independent pretreatment factors associated with mortality in all patients were AFP ≥ 400 ng/mL (hazard ratio (HR) 2.00, 95% confidential interval (95% CI) 1.08-2.09, p < 0.0001), modified albumin-bilirubin (ALBI) grade 2b or 3 (HR 1.56, 95% CI 1.09-2.17, p = 0.012), major vascular invasion (HR 1.91, 95% CI 1.26-2.89, p = 0.0022), PS > 0 (HR 1.50, 95% CI 1.09-2.08, p = 0.014), and MTT (molecular targeted therapy) experience (HR 2.22, 95% CI 1.56-3.13, p = 0.00038). In the MTT naïve patients with ALBI grade 1 or modified ALBI 2a and BCLC stage B (n = 68), median OS and PFS were 25.3 and 12.3 months. Liver-related adverse events during LEN were the only significant adverse event associated with OS (HR 2.74, 95% CI 1.93-3.88, p < 0.0001). Among the Child-Pugh A patients with extrahepatic metastasis and no major vascular invasion, median PFS in the patients with bone metastasis was significantly shorter than those with lung or adrenal grand metastasis (6.3 vs. 12.5 months, p = 0.0025). CONCLUSION: LEN showed a high response rate in real-world practice. Pretreatment factors, including ALBI score, AFP, and major vascular invasion are important in making a treatment strategy for patients with u-HCC. The patients with bone metastasis would be candidates for new therapeutic approaches.
RESUMEN
PURPOSE: Fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX, FFX) and gemcitabine plus nab-paclitaxel (GnP) are considered standard treatments for patients with metastatic pancreatic cancer. Direct comparisons are not available that establish which is optimal. METHODS: We conducted a propensity score-adjusted analysis of patients with metastatic pancreatic cancer to identify the therapeutic advantages of these standard therapies. We used clinical data as part of a multicenter retrospective study of patients with unresectable or recurrent pancreatic cancer treated with FFX or GnP (NAPOLEON study). RESULTS: FFX and GnP were initially administered to 102 and 153 patients, respectively. The GnP group comprised more patients of advanced age, worse performance status, lower body mass index, recurrence, and lower albumin concentrations. Median overall survival (OS) and progression-free survival (PFS) were 11.5 months and 5.8 months in the FFX group and 11.1 months and 5.9 months in the GnP group, respectively. Propensity score-adjusted analysis indicated that the administration of FFX or GnP was not independently associated with OS (adjusted hazard ratio [HR] 1.06; 95% confidence interval [CI] 0.76-1.47; P = 0.73). Similarly, the difference in PFS was not significant between groups (adjusted HR 0.93; 95% CI 0.68-1.26; P = 0.62). Gastrointestinal disorders were more common in the FFX group, whereas the frequencies of hematological, nervous system, and skin disorders were higher in the GnP group. CONCLUSION: The efficacies of FFX and GnP were comparable, although safety profiles differed and should be considered in selecting treatment.
RESUMEN
AIM: The present study aimed to determine the real-world efficacy and safety of the non-structural protein (NS)5A inhibitor elbasvir (EBR) combined with the NS3/4A protease inhibitor grazoprevir (GZR) in patients with hepatitis C virus (HCV) genotype 1 (GT1) infection. METHODS: This study retrospectively evaluated the rate of sustained virologic response at 12 weeks post-treatment (SVR12) and the safety of EBR/GZR treatment in 159 men and 194 women with a median age of 72 years, and it assessed factors associated with the SVR12 rate. The attending physicians were responsible for selecting candidate patients for EBR/GZR in this retrospective study. RESULTS: Treatment outcomes for EBR/GZR were good in direct-acting antiviral (DAA)-naïve patients, of whom 99.4% achieved SVR. Of 353 patients, 10 (2.9%) had treatment failure. Of these patients, eight previously underwent DAA therapy, and the remaining two had NS5A-L31/Y93 double mutation. The SVR rate was 50% (8/16 patients) in patients who previously underwent DAA therapy, and 18.2% (2/11 patients) in patients with NS5A-L31/Y93 double mutation. On multivariate logistic regression analysis, NS5A-Y31/Y93 double mutation (odds ratio 356.3; 95% confidence interval, 23.91-16 940; P < 0.0001) was identified as an independent predictor of treatment failure. No serious adverse events were observed with EBR/GZR therapy. CONCLUSIONS: The SVR rate of EBR/GZR would have been 100% in patients without either a history of DAA therapy or double mutation. This combination of drugs could be safely given and is, thus, considered a highly useful first-line treatment for DAA-naïve patients with HCV.
RESUMEN
AIM: This study aimed to describe the real-world efficacy and safety of sofosbuvir (SOF) + ribavirin (RBV) for chronic hepatitis C, genotype 2. METHODS: This was a retrospective analysis of a nationwide, multicenter registry including 914 hepatitis C genotype 2 Japanese patients treated with SOF + RBV for 12 weeks. The rate of sustained virologic response at 12 weeks after treatment (SVR12), incidence of adverse events, and changes in serological parameters were analyzed. RESULTS: Treatment was completed in 98.9% of patients. Ribavirin dose reduction was required in 29.7% of patients. The SVR12 rate was 96.8% in the intention-to-treat population and 97.6% in the per-protocol population. Factors associated with SVR12 were absence of advanced fibrosis (odds ratio, 5.76, P = 0.003) and interferon-treatment-naïve status (odds ratio, 4.79, P = 0.017). Dose reduction or total adherence of RBV was not associated with SVR. The resistance-associated substitution S282 T in NS5B was not detected in any patient at virologic failure. Serum albumin levels significantly increased, and the degree of increase was greater in patients with advanced fibrosis than in those without (0.21 ± 0.32 vs. 0.05 ± 0.29, P < 0.0001). Alpha-fetoprotein decreased significantly at end of treatment (P < 0.0001), and the degree of decrease was greater in patients with advanced fibrosis than in those without (21.7 ± 60.8 vs. 2.5 ± 15.5, P < 0.001). The most commonly reported adverse event was anemia (13.7%). CONCLUSIONS: Treatment with SOF + RBV was highly effective and safe in Japanese patients with HCV genotype 2 infection.
RESUMEN
BACKGROUND AND AIM: This study aimed to elucidate whether interferon (IFN)-free direct-acting antiviral (DAA) therapy for hepatitis C after curative treatment of hepatocellular carcinoma (HCC) promotes HCC recurrence in a real-world large-scale cohort. METHODS: This multicenter study was conducted by the Japanese Red Cross Hospital Liver Study Group. This retrospective study analyzed 516 patients who underwent antiviral treatment for hepatitis C with either IFN (n = 148) or IFN-free DAA (n = 368) after curative HCC treatment; 78 IFN-treated patients and 347 IFN-free DAA-treated patients achieved sustained virological response (SVR). The recurrence rate of HCC was compared between the antiviral therapies. Logistic analysis and Cox proportional hazards analysis identified factors associated with early recurrence of HCC within 24 weeks of antiviral therapy and recurrence throughout the observation period, respectively. RESULTS: AFP at the completion of antiviral therapy, clinical stage of HCC, and non-SVR were independent factors associated with early recurrence of HCC. Among patients who had achieved SVR, the clinical stage of HCC and the level of AFP at completion of antiviral therapy were independent factors associated with early recurrence of HCC. For recurrence throughout the observation period in SVR patients, AFP at completion of antiviral therapy, duration between last HCC treatment to antiviral therapy, and the number of treatments were independent factors. There was no significant difference in the rate of early recurrence of HCC or recurrence throughout the observation period between IFN and IFN-free DAA treated patients. CONCLUSIONS: There were no differences in the early recurrence rate of HCC between patients who underwent IFN and those who underwent IFN-free DAA as antiviral therapies.
