High post-treatment absolute monocyte count predicted hepatocellular carcinoma risk in HCV patients who failed peginterferon/ribavirin therapy.

Salient studies have investigated the association between host inflammatory response and cancer. This study was conducted to test the hypothesis that peripheral absolute monocyte counts (AMC) could impart an increased risk of hepatocellular carcinoma (HCC) development in hepatitis C virus (HCV)-infected patients after a failed peginterferon/ribavirin (PR) combination therapy. A total of 723 chronic HCV-infected patients were treated with PR, of which 183 (25.3 %) patients did not achieve a sustained virological response (non-SVR). Post-treatment AMC values were measured at 6 months after end of PR treatment. Fifteen (2.8 %) of 540 patients with an SVR developed HCC during a median follow-up period of 41.4 months, and 14 (7.7 %) of 183 non-SVR patients developed HCC during a median follow-up of 36.8 months (log rank test for SVR vs. non-SVR, P = 0.002). Cox regression analysis revealed that post-treatment AFP level (HR 1.070; 95 % CI = 1.024-1.119, P = 0.003) and post-treatment aspartate aminotransferase (AST)-to-platelet ratio index (APRI) ≥0.5 (HR 4.401; 95 % CI = 1.463-13.233, P = 0.008) were independent variables associated with HCC development for SVR patients. For non-SVR patients, diabetes (HR 5.750; 95 % CI = 1.387-23.841, P = 0.016), post treatment AMC ≥370 mm(-3) (HR 5.805; 95 % CI = 1.268-26.573, P = 0.023), and post-treatment APRI ≥1.5 (HR 10.905; 95 % CI = 2.493-47.697, P = 0.002) were independent risks associated with HCC. In conclusion, post-treatment AMC has a role in prognostication of HCC development in HCV-infected patients who failed to achieve an SVR after PR combination therapy.

Survival Benefit of Experience of Liver Resection for Advanced Recurrent Hepatocellular Carcinoma Treated with Sorafenib: A Propensity Score Matching Analysis.

Several studies have shown that liver resection (LR) confers better survival outcomes in intermediate- and advanced-stage hepatocellular carcinoma (HCC) patients. However, the postoperative recurrence rate is high, and little is known about the survival benefits of LR for recurrent HCC patients who have already received systemic treatment. This study aimed to evaluate the impact of LR on recurrent advanced-stage HCC patients who received sorafenib as a systemic treatment. In this study, 147 advanced HCC patients were enrolled between 1 January 2012 and 31 December 2019. Two study groups were classified, based on whether they underwent LR or not. To reduce the possible selection bias, a propensity score matching (PSM) analysis was performed. The primary study endpoint was set as overall survival (OS), and the secondary endpoint was set as progression-free survival (PFS). Our study results revealed that advanced HCC patients who received sorafenib with LR had a longer OS than did those without LR, whether before or after PSM (15.0 months vs. 6.0 months, HR 0.45, 95% CI 0.31-0.67, p < 0.001; 15.0 months vs. 5.0 months, HR 0.46, 95% CI 0.28-0.76, p = 0.001). Similar results were obtained in PFS, before or after PSM (4.14 months vs. 2.60 months, HR 0.60, 95% CI 0.40-0.89, p = 0.01; 4.57 months vs. 2.63 months, HR 0.58, 95% CI 0.34-0.97, p = 0.037). Multivariate analysis showed that the experience of LR was independent of other factors associated with better OS and PFS, whether before or after PSM (p < 0.05). Therefore, advanced HCC patients who have undergone liver resection should be encouraged to continue sorafenib treatment to improve prognosis.

Neutrophil-to-lymphocyte ratio associated with mortality in early hepatocellular carcinoma patients after radiofrequency ablation.

BACKGROUND AND AIM: Increasing evidence correlates the presence of systemic inflammation with poor survival in patients with hepatocellular carcinoma (HCC). We studied whether peripheral blood neutrophil-to-lymphocyte ratio (NLR), a marker of systemic inflammatory response, would be a useful predictor for outcome in patients with early HCC undergoing radiofrequency ablation (RFA). METHODS: A total of 158 patients with early HCC underwent RFA. Potential prognostic factors such as age, gender, tumoral characteristics, Child-Turcotte-Pugh (CTP) class and NLR were analyzed. The study endpoints were overall survival (OS) and new recurrence. RESULTS: We modeled NLR as a continuous explanatory variable in regression analyses. Multivariate analysis revealed that tumor size (P = 0.005) and high baseline NLR (P = 0.001) were independent explanatory variables associated with unfavorable OS. Regarding new recurrence, multivariate analysis showed that CTP class B (P = 0.002), α-fetoprotein > 400 ng/mL (P = 0.030), tumor size (P = 0.002) and tumor multiplicity (P = 0.013) were found to be worse prognosticators, but not baseline NLR. In a subset analysis of 140 patients whose post-RFA NLR data at first follow-up visit were available, multivariate analysis revealed that high post-RFA NLR was identified as an independent covariate, not only for OS (P = 0.006), but for new recurrence (P = 0.010) as well. CONCLUSIONS: High baseline NLR was associated with worse OS for patients with early HCC; post-RFA NLR predicted not only OS, but also tumor recurrence.

Metformin associated with lower mortality in diabetic patients with early stage hepatocellular carcinoma after radiofrequency ablation.

BACKGROUND AND AIM: Type 2 diabetes increases the risk of cancer development and mortality. However, antidiabetic treatment with metformin can reduce the risk of cancer. We studied whether metformin users among diabetic patients with early hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA) would have a favorable survival compared with those without metformin treatment. METHODS: A total of 135 patients with early stage HCC having 162 tumors underwent RFA. Among them, 53 patients were diabetic, including 21 metformin users and 32 patients without metformin treatment. RESULTS: Diabetic patients had an inferior survival rate compared with nondiabetic patients (1 year, 82.8% vs 93.9%; 3 years, 55.1% vs 80.2%; 5 years, 41.3% vs 64.7%; P = 0.004). With regards to antidiabetic treatments, metformin users had better survival outcome (adjusted hazard ratio [HR] 0.24; 95% confidence interval [CI], 0.07-0.80; P = 0.020) compared to patients without metformin treatment after adjustments for potential confounders. Sulfonylureas and insulin exposures did not achieve significant conclusions. For the whole studied population including nondiabetic and diabetic patients, the multivariate analysis revealed that maximum tumor size more than 2.5 cm (HR, 3.49; 95% CI, 1.74-6.99; P < 0.001) and diabetic patients without metformin treatment (HR, 3.34; 95% CI, 1.67-6.71, P = 0.001) were independent explanatory variables associated with unfavorable survival. CONCLUSIONS: Metformin users among diabetic patients with HCC undergoing RFA had a favorable overall survival compared with patients without metformin treatment.

Feasibility of individualized treatment for hepatitis C patients in the real world.

BACKGROUND AND AIM: Individualized treatment with a combination of peg-interferon and ribavirin for patients with hepatitis C virus (HCV) infection has been validated in randomized controlled clinical trials, but its usefulness in the real world is unknown. The aim of the present study was to assess the feasibility of individualized treatment for HCV patients compared with standard therapy in a real-life clinical setting. METHODS: A total of 253 naïve patients with HCV infection who received peg-interferon and ribavirin combination treatment were analyzed and grouped into one of three clinical settings: (i) infection with genotype non-1 (HCV non-1) and treatment for standard 24 weeks (n = 105; none received an abbreviated therapy); (ii) genotype 1 (HCV-1) and standard therapy for either 24 weeks (n = 71) or 48 weeks (n = 21); and (iii) HCV-1 and individualized treatment (n = 56). The individualized therapy used was an abbreviated 24-week treatment for HCV-1 patients who achieved a rapid virological response, otherwise patients received a 48-week course of treatment. Early termination of treatment at week 16 was recommended for non-responders. RESULTS: A sustained virological response (SVR) was achieved in 83.8% of patients with HCV non-1 infection. Among the HCV-1-infected patients, 53.5% of patients who underwent standard 24-week treatment, 66.7% of patients who underwent standard 48-week treatment, and 64.3% of patients treated by individualized therapy achieved SVR. Patients infected with HCV-1 and treated by individualized therapy had a similar efficacy response compared with the standard 48-week therapy (adjusted odds ratio [OR] 0.765, 95% confidence interval [CI], 0.220-2.659, P = 0.673). Both individualized therapy (adjusted OR 2.855, 95% CI 1.189-6.855, P = 0.019) or standard 48-week treatment (adjusted OR 3.733, 95% CI 1.073-12.986, P = 0.038) had significantly higher odds of SVR compared with HCV-1 patients treated by standard 24-week course. CONCLUSION: Individualized therapy is feasible in the real world, especially for patients with HCV-1 infection.

Major complications of ultrasound-guided percutaneous radiofrequency ablations for liver malignancies: single center experience.

BACKGROUND AND AIM: Despite radiofrequency ablation (RFA) for malignant liver nodular lesions having promising therapeutic effects, the trade-off between the risks and benefits must be acceptable. This study analyzed the major complications of ultrasound (US)-guided percutaneous RFA procedures encountered at a single center, by a single physician. METHODS: A total of 104 patients (total 183 tumors) underwent 172 US-guided percutaneous RFA sessions between May 2003 and March 2006. The definition of major complications was according to the standardized Society of Interventional Radiology grading system (classification C-E). RESULTS: Eighty-six patients had hepatocellular carcinoma (HCC) and 18 patients had hepatic metastatic tumors. Nine major complications occurred from 172 RFA sessions (9/172, incidence of 5.2% per session); namely, two cases of transient liver function impairment, two cases of infection (liver abscess and septicemia), two cases of tumor seeding along the ablated track, one case of colon perforation, one case of acalculous cholecystitis and, lastly, a case of hemocholecyst. We further analyzed the possible risk factors precipitating these complications, and found that only tumor size (Pearson's correlation coefficient, 0.324; P < 0.05) and baseline liver function reserve (compensated 0%, 0/148 vs decompensated 8.3%, 2/24; P = 0.019) were significant factors for the complication of transient liver function impairment. CONCLUSION: Radiofrequency ablation for liver malignancy is a safe procedure with acceptable incidence of complications. Decompensated baseline liver function reserve and large tumor size are precipitating factors for transient liver function impairment after RFA and warrant a close follow up.

Management and patient survival in hepatocellular carcinoma: does the physician's level of experience matter?

INTRODUCTION: The prognostic determinants of hepatocellular carcinoma (HCC) depend on tumor stage, liver function reserve, and treatments offered. The clinical impact of the physician's experience on HCC management and the survival outcome is unknown. METHODS: A total of 103 patients were managed by one high-volume physician and 249 patients by seven low-volume physicians. The experience of high-volume physician in HCC management was five times more than that of low-volume physicians. Patient survival was the single end point for this study. RESULTS: Compared to the low-volume physician group, more of the patients allocated to the high-volume physician had early stage HCC on the date of diagnosis (66/103, 64.1%; vs 119/249, 47.8%; P = 0.008), and they received curative therapies including radiofrequency ablation or liver resection (66/103, 64.1% vs 54/249, 21.7%, P < 0.001), and had significantly better survival outcome (median survival of 34 months, 95% confidence interval [CI], 17.6-50.4; vs 6 months, 95% CI, 4.3-7.7; P < 0.001) with a multivariable-adjusted hazard ratio (HR) for survival of 1.94 (95%, CI, 1.31-2.87, P < 0.001). A multivariate analysis of the pretreatment prognostic factors for these two groups identified alpha-fetoprotein (AFP) level (HR, 1.42; 95% CI, 1.01-1.99; P = 0.042), ascites (HR, 1.68; 95% CI, 1.15-2.46; P = 0.007), maximum tumor diameter (HR, 1.78; 95% CI, 1.16-2.74; P = 0.009), and portal vein thrombosis (PVT) (HR, 2.17; 95% CI, 1.49-3.17; P < 0.001) as independent factors for the low-volume physician group. However, only maximum tumor diameter (HR, 4.54; 95% CI, 1.77-11.67; P < 0.001) and PVT (HR, 5.73; 95% CI, 2.30-14.22; P = 0.002) were independent factors for the high-volume physician group. CONCLUSION: The survival of HCC patients was dependent on the level of experience of the physicians who oversaw these patients.

Autoimmune chronic pancreatitis.

BACKGROUND: Autoimmune pancreatitis (AIP) is a unique form of chronic pancreatitis that is characterized by swelling of the pancreas, narrowing of the main pancreatic duct (MPD), elevation of serum gamma globulin, or immunoglobulin G or presence of autoantibody, lymphoplasmacytic infiltration and dense fibrosis on histopathology. It is responsive to steroid therapy. The incidence of AIP can reach 5-6% of chronic pancreatitis. It can present as obstructive jaundice, body weight loss, and pancreas head mass mimicking pancreatic cancer. The recognition of AIP can avoid major surgery such as pancreatic resection. METHODS: From May 2003 to July 2007, a total of 5 cases of AIP were reviewed retrospectively. The diagnosis was made on imaging study, serology, steroid response and/or histology if surgery was carried out. RESULTS: There were 2 male and 3 female patients, with a mean age of 61 (39-75) years. Atypical AIP was found in the first case and typical AIP in the remaining 4. The presenting clinical pictures were mild epigastric pain, obstructive jaundice, and loss of body weight in 4 cases, with associated autoimmune disease in 1. Diffuse or long segmental enlargement of the pancreas without peripancreatic fat infiltration was found in all patients except 1 who only had focal pancreatic head enlargement. Distal common bile duct (CBD) stricture was seen in 4 cases and the median CBD stricture length was 1.2 (0.5-2.5) cm. Multiple narrowing of the whole MPD was seen in 2 cases, focal narrowing of the MPD in 2 and long segmental narrowing of the MPD in 1. Serum immunoglobulin G tests were done in 4 cases and were elevated in all. Antinuclear antibody was positive in 3. The first case was operated on after a preoperative diagnosis of suspicious pancreatic head tumor. The subsequent 3 cases were diagnosed correctly as AIP. The last case presented with distal CBD stricture and hypoechoic lesion in the pancreas head on endoscopic ultrasound, with only borderline pancreatic enlargement on computed tomography, and he was operated on. Retrospective endoscopic retrograde pancreatogram review revealed MPD narrowing in the pancreatic body. Endoscopic retrograde brush cytology was performed and was negative for malignancy in 3 cases. Steroid therapy was given in 3 and was responsive, but there were 2 recurrences. CONCLUSION: AIP should be a differential diagnosis in distal CBD stricture and pancreatic head mass when the patient has: (1) diffuse or long segmental enlargement of the pancreas without peripancreatic fat infiltration, with multiple narrowing of the MPD without much upstream dilatation, or narrowing of the MPD not corresponding to the region of CBD stricture; and (2) abnormal immunoserologic tests.

Endoscopic mucosal resection of early esophageal carcinoma--experience of 9 cases.

BACKGROUND: Early esophageal mucosal carcinoma (M1 and M2) can be treated by ablation, or by endoscopic resection such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection. Endoscopic resection enables pathologic examination of resected specimens. We hereby report our experiences with early esophageal cancer and its endoscopically observed types, chromoendoscopy with Lugol's iodine and EMR results. METHODS: Between May 2003 and July 2007, 9 patients with early esophageal carcinoma underwent EMR. The diagnosis was made by conventional endoscopy (waiting for the relaxed phase during esophageal peristalsis) followed by chromoendoscopy using 3% Lugol's iodine to stain suspected early lesions or in high-risks patients. Miniprobe endoscopic ultrasound examinations were performed in all cases except 1. EMRs were carried out with a cap-fitted endoscope (EMRC). RESULTS: There were 6 male and 3 female patients, with a median age of 53 years (range, 44-83 years). Six of the 9 cases had a history of smoking, 5 had a history of drinking, and 4 had a history of betel nut chewing. The endoscopic pictures of the early cancers were type 0-IIa (1 case), type 0-IIb (2 cases), and type 0-IIc (6 cases). One patient had double 0-IIc lesions. Two 0-IIb cases were detected only by chromoendoscopy using Lugol's iodine staining. The median size of the lesions was 0.85 cm (range, 0.7-2.0 cm). The final pathology reports of the endoscopically resected specimens were well-differentiated squamous cell carcinoma with free vertical and lateral margins, and no vascular or lymphatic invasion. The depths of tumor invasion were mucosal layer M1 in 7 cases, M2 in 1 case, and submucosal layer SM1 in the remaining case. There were no perforation or bleeding complications. The mean follow-up period was 13.1 months (range, 4-46 months). A M2 early esophageal cancer measuring 2 cm in diameter recurred 6 months after piecemeal EMRC. No additional adjuvant therapy was given to the SM1 case owing to her old age and bedridden condition. CONCLUSION: Early esophageal cancer can be diagnosed by meticulous examination of the esophageal mucosa with conventional endoscopy, facilitated by Lugol's iodine staining, and can be treated by EMR, which is safe. Recurrence can occur after piecemeal EMR.

Linear endoscopic ultrasound for clinically suspected bile duct stones.

BACKGROUND: Radial endoscopic ultrasound (EUS) is a less invasive imaging modality used to evaluate common bile duct stones (CBDS) and is as accurate as endoscopic retrograde cholangiography (ERCP). Patients classified as high risk for suspected CBDS were found to have stones in only two-thirds of cases, and an argument could be made for performing EUS in these high-risk patients. There are very few reports of linear EUS for CBDS detection. Our aim was to evaluate the diagnostic efficiency of linear EUS in patients with suspected CBDS in intermediate- and high-risk groups. METHODS: This is a retrospective analysis of prospectively collected data for 30 patients with suspected CBDS assessed using linear EUS. The inclusion criteria were acute epigastric pain, abnormal liver function test (LFT), and CBDS not detected by transabdominal ultrasound or computed tomography. The exclusion criteria were failure to insert a linear EUS endoscope into the duodenum and Billroth II gastrectomy. ERCP was performed in patients with positive CBDS on linear EUS. Cases with negative CBDS after linear EUS examination were followed in terms of clinical symptoms and LFT for at least for 3 months as outpatients. RESULTS: There were 17 male and 13 female patients with a mean age of 53 (±17.6) years. Twelve cases were positive for CBDS, of which 11 were confirmed by ERCP and one was a false positive. In cases with negative CBDS on linear EUS, the median follow-up duration was 9 (3-12) months. The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100%, 94.7%, 91.7%, 100%, and 96.7%, respectively. CBDS was positive in 56% (9/16) of high-risk patients and 14.3% (2/14) of intermediate-risk patients. CONCLUSION: Linear EUS is sensitive for the detection of CBDS. It detected 56% of CBDS in a high-risk group and 14.2% in an intermediate-risk group and therefore is a useful assessment tool in patients with high or intermediate risk of CBDS.

An uncommon cause of hiccups: sarcoidosis presenting solely as hiccups.

Common causes of hiccups are over-distension of the stomach, a sudden change in gastrointestinal temperature, excessive alcohol and tobacco ingestion, and sudden excitement or emotional changes. Common presenting symptoms of sarcoidosis include cough, dyspnea, and chest pain. It is very rare for a sarcoidosis patient to present with hiccups. A 48-year-old man presented with hiccups of 2 weeks' duration. He denied having headaches, earache, cough, abdominal pain, fever, or body weight loss history. On physical examination, he had no peripheral lymphadenopathies in the neck, axilla and inguinal regions, no organomegaly in the abdomen and no skin abnormalities. A neurological examination showed normal findings. Laboratory investigations revealed a normal complete blood count, liver function, renal function, serum calcium, and tumor markers. Transabdominal ultrasound was negative, and panendoscopy revealed a small healing duodenal ulcer. Chest radiography showed an enlarged right lung hilum, while computed tomography showed enlargement of multiple mediastinal lymph nodes. Endoscopic ultrasound-guided fine-needle aspiration with a 22-gauge needle and trucut biopsy with a 19-gauge needle (quick-core biopsy needle) were performed, and cytology, cell block and histology revealed non-caseating granuloma, with negative tuberculous and fungus cultures. Mediastinal lymph node due to sarcoidosis can be a rare cause of hiccups.

Role of endoscopic ultrasound-guided fine-needle aspiration in lung and mediastinal lesions.

BACKGROUND: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was initially introduced for diagnosing gastrointestinal and pancreatic lesions, and later on for lung and mediastinal lesions. It can provide tissue diagnosis of lung cancer where bronchoscopy is non-diagnostic. It is a minimally invasive method for lymph node (N) and metastasis (M) staging of non-small cell lung cancer, and is helpful for tissue proof of mediastinal mass with unknown origin. Few data on this topic have been reported from Eastern countries. We report our experience of using EUS-FNA for tissue proof of lung and mediastinal lesions. METHODS: This was a retrospective analysis of prospectively collected data of 20 cases, with 21 EUS-FNAs of lung and mediastinal lesions (1 EUS-FNA performed on left adrenal gland) for tissue diagnosis and staging. With patients' informed written consent and fasting for 8 hours, EUS-FNA was performed with a linear echoendoscope using a 22- or 5-gauge needle and a syringe with 10-20 mL negative pressure. The cytology smear was fixed with 98% alcohol, while cell-block and tissue were sent for histology. There was no onsite cytopathologist. EUS-guided Tru-Cut biopsy was performed in 1 case. Malignancy was proven by FNA biopsy results, mediastinoscopy when performed, or by clinical course and follow-up. RESULTS: Of the 20 cases, 19 were male and 1 was female; mean age was 63.9 ± 12.6 years. Median tumor size was 2.6 cm (range, 1.8-5.0 cm), and median number of punctures was 3 (range, 2-7). Eighteen EUS-FNA punctures were performed at the mediastinum, and 2 directly on lung mass. The size of the left adrenal metastasis for extramediastinal EUS-FNA was 1.2 cm. Of the 16 EUS-FNA-positive cases, 12 were for tissue diagnosis, 3 were for both tissue diagnosis and staging (N2 and M1 staging), and 1 was for N2 staging. EUS-FNA provided a tissue diagnosis in 14 cases where bronchoscopy was negative. In 16 positive EUS-FNAs, all except 1 had adequate tissue for FNA biopsy. The sensitivity, specificity, and diagnostic accuracy of EUS-FNA were 84.2%, 100%, and 85%, respectively. CONCLUSION: EUS-FNA can diagnose lung cancer by confirmation of mediastinal lymph node metastasis, by direct puncture of lung tumor close to the esophagus. It is useful for lymph node (N) stations 5, 7, 8 and metastasis (M) staging in non-small cell lung cancer, and for the diagnosis of mediastinal mass of unknown etiology.

Predictors of alpha-fetoprotein elevation in patients with chronic hepatitis C, but not hepatocellular carcinoma, and its normalization after pegylated interferon alfa 2a-ribavirin combination therapy.

BACKGROUND AND AIM: Elevated serum alpha-fetoprotein (AFP) levels are noted in patients with chronic hepatitis C (CHC) without hepatocellular carcinoma (HCC). The change in AFP levels after treatment with pegylated interferon and ribavirin (Peg-IFN/RBV) combination therapy is still unknown. The aim of this study was to investigate the predictors of elevated serum AFP in patients with CHC, and its change after Peg-IFN/RBV therapy. METHODS: A total of 123 patients, intended to receive pegylated interferon alfa-2a plus ribavirin therapy, were enrolled. Eighty-three patients had complete treatment and received follow up for and additional 24 weeks. The factors that may affect the elevation of pretreatment AFP and the normalization of post-treatment AFP were determined. RESULTS: The mean AFP level was 18.5 +/- 63.0 ng/mL (range, 1.3-676.0 ng/mL); 41 (33.3%) of the 123 patients had elevated serum AFP (more than 10 ng/mL) at baseline. A multivariate logistic regression analysis disclosed that older age (odds ratio [OR], 1.093; 95% confidence interval [CI], 1.015-1.177; P = 0.018), more advanced METAVIR fibrosis stage (OR, 5.237; 95% CI, 1.244-22.037; P = 0.024), a higher aspartate aminotransferase (AST) level (IU/L) (OR, 1.020; 95% CI, 1.008-1.033; P = 0.001), and lower platelet count (x10(9)/L, OR, 0.985; 95% CI, 0.968-0.994; P = 0.003) were independent determinants of pretreatment AFP elevation. After treatment, 72 of 83 (86.7%) cases were found to have normal post-treatment AFP levels (<10 ng/mL) at the end of follow up (EOF). Post-treatment negativity of the chronic hepatitis C virus (HCV)-RNA (OR, 10.014; 95% CI, 1.000-100.329; P = 0.050) and the post-treatment platelet count (x10(9)/L) (OR, 1.025; 95% CI, 1.001-1.050; P = 0.040) were associated with normal AFP at EOF. AFP progressively decreased with significant differences starting from the 12th week after treatment to the end of treatment, and was lowest at the EOF date for the sustained viral response (SVR) group. On the contrary, the non-SVR group did not have an AFP change during and after treatment. CONCLUSION: Older age, low platelet count, higher AST levels, and advanced fibrosis predisposed chronic hepatitis C patients without HCC to have elevated serum AFP levels. After Peg-IFN/RBV combination therapy, a higher platelet count and HCV viral eradication were determinants of normal AFP at EOF. Serial AFP levels decreased after treatment, presenting in a time-dependent manner, specifically for the SVR group.
