ABSTRACT
BACKGROUND: The clinical trend and characteristics of peptic ulcer disease (PUD) have not fully been investigated in the past decade. AIM: To evaluate the changing trends and characteristics of PUD according to age and etiology. METHODS: We analyzed seven hospital databases converted into the Observational Medical Outcomes Partnership-Common Data Model between 2010 and 2019. We classified patients with PUD who underwent rapid urease tests or Helicobacter pylori (H. pylori) serology into three groups: H. pylori-related, drug [nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin]-related, and idiopathic (H. pylori/NSAID/aspirin-negative) PUD and compared the yearly trends and characteristics among the three groups. RESULTS: We included 26785 patients in 7 databases, and the proportion of old age (≥ 65 years) was 38.8%. The overall number of PUD exhibited no decrease, whereas PUD in old age revealed an increasing trend (P = 0.01 for trend). Of the 19601 patients, 41.8% had H. pylori-related, 36.1% had drug-related, and 22.1% had idiopathic PUD. H. pylori-related PUD exhibited a decreasing trend after 2014 (P = 0.01), drug-related PUD demonstrated an increasing trend (P = 0.04), and idiopathic PUD showed an increasing trend in the old-age group (P = 0.01) during 10 years. Patients with drug-related PUD had significantly more comorbidities and concomitant ulcerogenic drugs. The idiopathic PUD group had a significantly higher number of patients with chronic liver disease. CONCLUSION: With the aging population increase, the effects of concomitant ulcerogenic drugs and preventive strategies should be investigated in drug-induced PUD. Further studies are required to clarify the relationship between idiopathic PUD and chronic liver disease.

BACKGROUND/AIMS: Conflicting results have been reported regarding the interaction between proton pump inhibitors (PPIs) and clopidogrel. We investigated whether concomitant PPI use influenced the risk of recurrence in patients with stroke and myocardial infarction (MI). METHODS: This study used two databases for two different designs, the Korean National Health Insurance Service (NHIS) database for a self-controlled case series design, and the national sample cohort of the NHIS data base converted to the Observational Medical Outcomes Partnership-Common Data Model version for a cohort study based on large-scale propensity score matching. RESULTS: In the PPI co-prescription group, recurrent hospitalization with stroke occurred in 17.6% of the 8201 patients with history of stroke, and recurrent MI occurred in 17.1% of the 1216 patients with history of MI within1 year. According to the self-controlled case series, the overall relative risk (RR) of recurrent stroke was 2.09 (95% confidence interval (CI); 1.83-2.38); the RR showed an increasing trend parallel to the time from the beginning of PPI co-prescription. In the cohort study, there was a higher incidence of recurrent stroke in the PPI co-prescription group (Hazard ratio (HR): 1.34, 95% CI: 1.01-1.76, p = 0.04). The overall RR of recurrent MI was 1.47 (95% CI; 1.02-2.11) in the self-controlled case series; however, there was no statistically significant difference in recurrent MI in the cohort study (HR:1.42, 95% CI:0.79-2.49, p = 0.23). The impact of individual PPIs on stroke and MI showed different patterns. CONCLUSIONS: A PPI co-prescription >4 weeks with clopidogrel was associated with hospitalization of recurrent stroke within 1 year of initial diagnosis; however, its association with recurrent MI remains inconclusive. The influence of individual PPIs should be clarified in the future.
ABSTRACT
BACKGROUND: After endoscopic submucosal dissection of gastric neoplasms, surveillance endoscopy is required for patients with synchronous or metachronous neoplasms. We aimed to evaluate the risk factors associated with surveillance loss in patients who underwent endoscopic submucosal dissection. METHODS: Ninety-five patients treated with endoscopic submucosal dissection for gastric neoplasms between May 2015 and June 2016 were retrospectively reviewed. Clinicopathologic factors, sociodemographic factors, psychiatric measures, and associated risk factors for surveillance loss were evaluated. The chi-square or Fisher exact test, t-test, and logistic regression analysis were used in data analysis. RESULTS: Twenty-five (26.3%) patients were identified as having surveillance loss. Compared to the surveillance group, the surveillance loss group was old and had dysplasia, and a healthy American Society of Anesthesiologists physical status. Similarly, surveillance loss was related to low symptom perception, low incidence of alexithymia, mindful awareness, and high trait forgiveness. Logistic regression analysis showed that dysplasia (odds ratio, 15.23; 95% CI, 1.56-149.09, P=0.019), old age (odds ratio, 7.14; 95% CI, 1.90-26.88, P=0.004), and American Society of Anesthesiologists physical status 1 (odds ratio, 3.99; 95% CI, 1.09-14.60, P=0.037) were associated with surveillance loss. CONCLUSIONS: Dysplasia, old age, and the American Society of Anesthesiologists physical status 1 were associated with surveillance loss in patients who underwent gastric endoscopic submucosal dissection. It could be helpful to proactively monitor patients with such conditions after gastric endoscopic submucosal dissection.
ABSTRACT
BACKGROUND/AIMS: To investigate whether visceral fat area (VFA) measured by bioelectric impedance analysis (BIA) was associated with metabolic syndrome in subjects with and without obesity. METHODS: A total 23,202 participants who underwent medical check-ups were assessed. Participants were stratified by body mass index (BMI) and VFA. We evaluated six different groups for metabolic syndrome: Group 1 (normal weight and low VFA), Group 2 (normal weight and high VFA), Group 3 (overweight and low VFA), Group 4 (overweight and high VFA), Group 5 (obesity and low VFA), and Group 6 (obesity and high VFA). RESULTS: Metabolic syndrome traits and metabolic syndrome were significantly more prevalent in the high-VFA (≥ 100 cm2 ) subgroup in each BMI group. Adjusted logistic regression analyses revealed that the odds ratio for metabolic syndrome compared with Group 1 was the highest in Group 6 (24.53; 95% confidence interval [CI], 21.77 to 27.64). Notably, the odds ratio of Group 2 was higher than that of Group 3 (2.92; 95% CI, 2.30 to 3.69 vs. 2.57; 95% CI, 2.23 to 2.97). CONCLUSION: Our study demonstrates that the combination of BMI assessment and VFA determination by BIA may be a useful method for predicting the risk of metabolic syndrome. The VFA by BIA may be a useful target for interventions to improve metabolic syndrome.

Very few population-based studies have examined the epidemiology of Wilson's disease (WD). We investigated the epidemiology of WD using the National Health Insurance Service (NHIS) database in South Korea. We analyzed not only the statistical variables of WD, but also those of WD-related diseases. WD patients were identified with the relevant International Classification of Diseases-10 code out of 50.5 million people. We used the NHIS database from 2009 to 2016 and analyzed the incidence rate, prevalence, and clinical symptoms of WD. A total of 1,333 patients were identified. The average annual incidence rate was 3.8 per million person-years. The prevalence was 38.7 per million people. The mean diagnostic age was 26.1 ± 17.2 with earlier diagnosis in men (P = 0.0003). Among the patients, 988 (74.1%) had hepatic symptoms, 510 (38.3%) had neurologic symptoms, and 601 (45.1%) had psychiatric symptoms. Before the diagnosis of WD, 350 (26.3%) had neurologic symptoms, and 427 (32%) had psychiatric symptoms. The annual mortality rate was 0.7%. Age, liver cirrhosis, and liver failure correlated with a fatal prognosis (P < 0.05). Many patients showed neurologic and psychiatric symptoms before they were diagnosed with WD. Prognosis correlated with age, liver cirrhosis, and liver failure.

The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.
ABSTRACT
This is a case report of successful endoscopic resection (ER) of a bleeding duodenal lipoma. An 85-year-old woman who was diagnosed with asymptomatic subepithelial tumor of the duodenum 3 years ago visited the emergency room with hematemesis and was admitted to our hospital. Emergent esophagogastroduodenoscopy revealed bleeding from an ulcer on the superior aspect of a subepithelial tumor measuring about 20 mm in diameter, at the superior duodenal angle. The ulcer was in the active stage (A1), with a visible vessel. The bleeding was controlled by ER of the tumor using a snare. The final pathological diagnosis was duodenal lipoma with mucosal ulceration. The patient showed no signs of bleeding for 10 days after the procedure; subsequently, she was discharged and followed up for regular checkups.
ABSTRACT
PURPOSE: To estimate long-term outcomes after treatment modification in patients with chronic hepatitis B (CHB) treated with entecavir (ETV) and telbivudine (LdT). MATERIALS AND METHODS: The study enrolled 131 nucleos(t)ide analogue (NA)-naïve CHB patients treated with ETV or LdT. During the 3-year study, NA treatment history including the incidence, the type of treatment modification, reasons for the modification, and overall complete virologic response (CVR) rate were retrospectively evaluated using the patients' medical records. RESULTS: Among the 131 patients, 84 and 47 were initially treated with ETV and LdT, respectively. During the course of 3-year study, 82 patients in the ETV group (97.6%) maintained initial treatment whereas only 19 in the LdT group (40.4%). In the LdT group, 26 patients (92.9%) switched to another NA and another NA was added in 2 (7.1%) patients. An assessment of the CVR rate at 3 years, including treatment modification, showed that 89.3% and 95.7% of patients in the ETV and LdT groups, respectively, had undetectable serum hepatitis B virus DNA levels (p=0.329). Among LdT patients with treatment modification, the cumulative incidence rate of a CVR for rescue therapy was significantly higher in the tenofovir than in the ETV group (p=0.009). CONCLUSION: During the 3-year study, there were no significant differences in the CVR between the ETV and LdT groups if appropriate rescue therapy was considered.

Surgery has been the standard treatment for perforated duodenal ulcers, with mostly good results. However, the resolution of postoperative leakage after primary repair of perforated duodenal ulcer remains challenging. There are several choices for re-operation required in persistent leakage from perforated duodenal ulcers. However, many of these choices are complicated surgical procedures requiring prolonged general anesthesia that may increase the chances of morbidity and mortality. Several recent reports have demonstrated postoperative leakage after primary repair of a perforated duodenal ulcer treated with endoscopic insertion using a covered self-expandable metallic stent, with good clinical results. We report a case with postoperative leakage after primary repair of a perforated duodenal ulcer treated using a covered self-expandable metallic stent.

BACKGROUND AND AIM: The prevention of post-endoscopic submucosal dissection (ESD) bleeding in high-risk patients is an important problem. This study evaluated the efficacy of polysaccharide hemostatic powder in preventing post-ESD bleeding in high-risk patients. METHODS: Patients at high risk for post-ESD bleeding were prospectively enrolled between December 2015 and July 2016. A high risk of post-ESD bleeding was considered if the patients were taking antithrombotic agents or had undergone a large resection (specimen size ≥ 40 mm). The endpoints were Forrest classification of the post-ESD ulcer on second-look endoscopy 2 days after the procedure and bleeding rates within 48 h and at 4 weeks. RESULTS: Forty-four patients underwent gastric ESD and treatment with hemostatic powder. Among them, 33 patients (70.5%) underwent large resection (≥ 40 mm) without antithrombotic therapy, and 13 patients (29.5%) received antithrombotic therapy. The mean resected specimen size was 55.3 ± 13.9 mm. The proportion of high-risk delayed bleeding lesions (Forrest IIa) at second-look endoscopy was 4.5% (2/44). The overall bleeding rate was 9.1% (4/44). There was no early bleeding event. The median (interquartile range) timing of bleeding after the procedure was 12.5 (interquartile range 10.3-15.5) days. The bleeding rate in the large resection (≥ 40 mm) group without antithrombotic therapy and the antithrombotic therapy group was 3.2% (1/33) and 23.1% (3/13), respectively. CONCLUSIONS: Hemostatic powder may be a promising new simple and effective method to prevent early post-ESD bleeding in high-risk patients, especially for those with larger resection. (Clinical trial registration number: NCT02625792).

BACKGROUND: The treatment of intramucosal early gastric cancer with undifferentiated-type histologies (UD-EGCs) using endoscopic submucosal dissection (ESD) is controversial. This study aimed to compare the clinical and oncologic long-term outcomes of ESD and surgery for UD-EGCs. METHODS: A prospectively collected database of patients who underwent ESD or surgery between January 2006 and December 2012 was established. Patients who diagnosed with UD-EGC and satisfied the expanded indications of ESD were included. Clinical data from 111 patients treated with ESD and 382 patients underwent surgery were analyzed, and 1-1 propensity score-matched 81 pairs of patients were also compared. RESULTS: In both groups, two-thirds of the UD-EGCs had signet ring cell (SRC)-type histology and about 90% of UD-EGCs were flat or depressed types. The mean size of tumors was smaller in ESD group (9.7 vs. 13.2 mm; P < 0.001). After propensity score-matched, case-matching covariates were not significantly different between the groups. Disease-free survival (DFS) was significantly shorter in the ESD group, but overall survival (OS) was not different between the two groups both in overall comparison (DFS; P < 0.001 and OS; P = 0.078) and propensity score-matched analysis (DFS; P < 0.001 and OS; P = 0.850). According to histologic type, OS of SRC histology was not different between the group, both in overall comparison and propensity score-matched analysis (P = 0.286 and P = 0.210). On the other hands, OS of poorly differentiated adenocarcinoma was significantly shorter in ESD group in overall comparison (P = 0.007), but was not as so in propensity score-matched analysis (P = 0.088). CONCLUSIONS: ESD might be a complementary option for the treatment of UD-EGCs, especially in those with SRC-type histology based on strict expanded indications. Nonetheless, close endoscopic surveillance is required because of a high incidence of intragastric recurrence.

BACKGROUND: Endoscopic submucosal dissection (ESD) is accepted as a standard treatment in patients with early gastric cancer (EGC) who have a negligible risk of lymph node metastasis. The aim of this study was to compare the short-term and long-term outcomes between ESD and surgery in patients with EGC that fulfilled the expanded indication of ESD on their final pathologic report. METHODS: We reviewed the clinical data of patients who underwent gastric ESD and surgery between January 2007 and December 2012. Patients with pathologically confirmed EGC that fulfilled the expanded indication of ESD on their final pathologic report were analyzed. RESULTS: Among 2023 patients, 817 (40.4%) underwent ESD and 1206 (59.6%) underwent surgery. The proportion of cases meeting the absolute indication was significantly higher in the ESD group than in the surgery group (66.0 vs. 26.2%). Lesions on the middle third, >3 cm in size, flat or depressed, and of undifferentiated histology were significantly more common in the surgery group than in the ESD group. The ESD group showed lower acute complication rates [8.1% (66 of 817) vs. 18.1% (218 of 1206), P ≤ 0.001] and procedure-related mortality [0 vs. 0.3% (4 of 1206), P = 0.153] than the surgical group. The annual incidence of recurrent gastric cancer was 2.18% in the ESD group and 0.19% in the surgery group. The 5-year overall and disease-specific survival rates were not significantly different between the ESD group and the surgery group (overall survival: 96.4 vs. 97.2%, P = 0.423; disease-specific survival: 99.6 vs. 99.2%, P = 0.203). CONCLUSIONS: Although EGC lesions had poorer features in the surgery group than in the ESD group, ESD was comparable to surgery for EGCs that fulfilled the expanded indication of ESD, with lower rates of acute complication and comparable overall survival.

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is routinely performed in treating gastric neoplasia and requires long-term higher levels of sedation. Endoscopist-directed nurse-administered sedation (EDNAS) has not been well studied in ESD. This study aimed to evaluate the safety and effectiveness of EDNAS for ESD. METHODS: Patients treated with ESD for gastric tumors between 2013 and 2015 were retrospectively collected. Patients were divided into a midazolam-treated group (M group) and a midazolam plus propofol-treated group (MP group). Clinical outcome, safety, effectiveness, adverse events of ESD, and adverse events of sedation were analyzed. RESULTS: Of 209 collected patients, 83 were in the M group and 126 were in the MP group. Of all patients, 67 patients had the circulatory adverse event during the ESD procedure. Sedation method was the only significant risk factor (M versus MP: 2.17 (1.14-4.15), p = 0.019). In analysis of MP subgroups, 47 patients suffered an adverse event from sedation, and current smoking was the only significant association factor for adverse event (0.15 (0.03-0.68), p = 0.014). CONCLUSIONS: In performing ESD, the effect of sedation is reduced in smoking patients. EDNAS may be acceptable for ESD under careful monitoring of vital sign and oxygen saturation.
ABSTRACT
BACKGROUND AND AIM: This study aims to evaluate clinical outcomes of patients with hepatocellular carcinoma who underwent transarterial chemoembolization (TACE) using drug-eluting beads (DEB). PATIENTS AND METHODS: This study retrospectively compared the clinical outcomes of 250 consecutive patients who underwent DEB-TACE (n = 106) or conventional TACE (cTACE) (n = 144) in a tertiary center between January 2010 and April 2014. The median age of the patients was 62 years and 81.6% were men. The primary endpoint was overall survival (OS). The time to progression (TTP), radiological response rate using modified response evaluation criteria in solid tumors criteria at 1 month after treatment, and complication rates within 1 month were also compared. RESULTS: The most common etiology was hepatitis B virus infection. The median index tumor size was 2.8 cm, and 150 (60.0%) patients had Barcelona Clinic Liver Cancer stage B. Median TTP in the cTACE group was longer than in the DEB-TACE group (13.3 vs10.8 months; P = 0.023). However, DEB-TACE and cTACE groups showed no significant differences for mean OS (46.6 vs 44.9 months; P = 0.660) and disease control rate at 1 month (78.3% vs 86.8%; P = 0.076). The OS, TTP, and disease control rate were also not different between two groups, even when subgrouped by index tumor size. The complication rates within 1 month were higher in the cTACE group (6.6% vs 14.6%; P = 0.048). CONCLUSIONS: Drug-eluting beads TACE appears to be a safe intra-arterial therapy. However, it is not superior to cTACE in terms of efficacy. Tumor size might not be a criterion to select treatment modality between cTACE and DEB-TACE in terms of efficacy.

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is a useful method for complete resection of early gastric cancer (EGC). However, there are still some patients who undergo additional gastrectomy after ESD because of non-curative resection. There is no model that can accurately predict non-curative resection of ESD. We aimed to create a model for predicting non-curative resection of ESD in patients with EGC. PATIENTS AND METHODS: We reviewed the medical records, including all gross findings of EGC, of patients who underwent ESD for EGCs. We divided the patients into a non-curative resection group and a curative resection group. The clinicopathologic characteristics were compared between the groups to identify the risk factors for non-curative resection of ESD. We created a scoring system based on logistic regression modeling and bootstrap validation. RESULTS: Of 1639 patients who had undergone ESD for EGCs, 272 were identified as being treated non-curatively with ESD. A large tumor size (≥20 mm), tumor location in the upper body of the stomach, the presence of ulcer, fusion of gastric folds, the absence of mucosal nodularity, spontaneous bleeding, and undifferentiated tumor histology were associated with non-curative resection of ESD. Points of risk scores were assigned for these variables based on the ß coefficient as follows: tumor size (≥20 mm), 2 points; tumor location in the upper body of the stomach, 1 point; ulcer, 2 points; fusion of gastric folds, 2 points; absence of mucosal nodularity, 1 point; spontaneous bleeding, 1 point; and undifferentiated histology, 2 points. Our risk scoring model showed good discriminatory performance on internal validation (bootstrap-corrected area under the receiver operating characteristic curve, 0.7004; 95% confidence interval, 0.6655-0.7353). CONCLUSIONS: We developed a validated prediction model that can be used to identify patients who will undergo non-curative resection of ESD. Our prediction model can provide useful information for making decisions about the treatment of EGC before performing ESD.

Humoral hypercalcemia of malignancy (HHM) is rarely associated with cholangiocarcinoma (CC), and represents dismal prognosis. A 63-year-old male was admitted for evaluation of an intrahepatic mass. He was diagnosed with HHM associated with locally advanced CC. As the tumor responded to the concurrent chemoradiotherapy with capecitabine and cisplatin, serum calcium level was normalized. However, according to the disease progression, he suffered recurrence of HHM and he expired approximately one year after initial diagnosis. A 68-year-old male who presented with abdominal pain was diagnosed with metastatic CC. After the eighth cycle of gemcitabine and cisplatin, progression of the disease was found with HHM. He was treated with the best supportive care, until his demise approximately one month after the diagnosis of HHM. We report on two cases of HHM associated with CC that demonstrate strong correlation between hypercalcemia and disease burden.
ABSTRACT
BACKGROUND: The clinical usefulness of tumor markers as predictors of treatment outcome in patients with stomach cancer after radical gastrectomy has been poorly defined. The purpose of this study was to evaluate a comprehensive understanding of the impact of early postoperative tumor marker normalization on survival after gastrectomy. METHODS: Between January 2001 and December 2007, we enrolled 206 patients who had received radical gastrectomy as an initial treatment and had elevated carcinoembryonic antigen (CEA) (>5 ng/mL) or carbohydrate antigen (CA) 19-9 (>37 U/mL) levels. Early tumor marker response was defined as a normalization of preoperative CEA or CA19-9 values 1-2 months after gastrectomy. RESULTS: The mean patient age was 61 years (range 29-84 years), and 139 patients (67.5%) were male. Early tumor marker response was identified in 150 of 206 (72.8%) patients. Of the patients, 49 (23.8%), 41 (19.9%), and 116 (56.4%) were stages I, II, and III, respectively, according to the seventh edition of the American Joint Commission on Cancer (AJCC) staging system. Both disease-free survival (DFS) and overall survival (OS) were significantly longer in patients with tumor marker response compared with nonresponse (61.5 vs. 37.6 months; P = 0.010 and 71.3 vs. 50.9 months; P = 0.008, respectively). Multivariate analyses showed that high CA19-9 level, early tumor marker response, and tumor, node, metastasis classification system stage were independent predictors of DFS and OS (P < 0.05). CONCLUSIONS: Early CEA or CA19-9 normalization after radical gastrectomy is a strong prognostic factor for gastric cancer, especially in patients with high preoperative levels of tumor markers.

BACKGROUND/AIMS: Alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) have been used as diagnostic tools for hepatocellular carcinoma (HCC). However, prediction of outcome using AFP and DCP has not been elucidated. We investigated the clinical role of AFP and DCP as predictors of treatment outcome in patients with HCC undergoing trans-arterial chemoembolization (TACE). METHODS: Between January 2003 and December 2005, we enrolled 115 treatment-naïve patients who received TACE as an initial treatment modality. An AFP or DCP response was defined as a reduction of more than 50% from the baseline level 1 month after TACE. Patients with AFP < 20 ng/mL or DCP < 20 mAU/mL were excluded. RESULTS: The median age was 59 years and the male gender predominated (n = 81, 70.4%). AFP and DCP response was identified in 91 (79.1%) and 77 (66.9%) patients after TACE. Although progression-free survival (PFS) did not differ according to AFP response (P = 0.150), AFP responders showed significantly better overall survival (OS) than non-responders (34.9 vs. 13.2 months; P = 0.002). In contrast, DCP response did not influence either PFS or OS (all P > 0.05). Multivariate analyses showed that gamma-glutamyltranspeptidase and baseline AFP were predictors of PFS (all P < 0.05) and that male gender, the presence of liver cirrhosis, baseline DCP, number of measurable tumors and AFP response were independent predictors of OS (all P < 0.05). CONCLUSIONS: AFP response and higher baseline DCP level are significant predictors of OS in treatment-naïve patients with HCC receiving TACE who showed pretreatment elevation of both AFP and DCP.
