ABSTRACT
Isolated fallopian tubal torsion is rare among women of reproductive age, and it is even rarer during pregnancy. Despite its rare incidence, it is important to consider this diagnosis to facilitate prompt and effective intervention. We present the case of a pregnant woman in her third trimester who presented with acute right abdominal pain. A 32-year-old primigravida woman at 29 weeks and four days of gestation visited the emergency department with acute right flank and abdominal pain. Sonography and MRI revealed the presence of a right adnexal cystic mass. Exploratory laparoscopy revealed isolated right tubal torsion and a normal ovary. To avoid torsion recurrence, we performed laparoscopic right salpingectomy. The remainder of her gestation was uneventful. Histopathological examination revealed serous cystadenoma with haemorrhagic infarction. We reviewed the literature for cases of isolated tubal torsion in the past 11 years. Twenty-three case reports were included in this study, and the average time from presentation to surgical intervention was 35.6 hours. In these cases, most of the patients underwent laparotomy and had good pregnancy outcomes. Although the approach may vary depending on the situation, the laparoscopic approach should be preferred to laparotomy in the third trimester of pregnancy.

PURPOSE: Vitamin D deficiency is common during pregnancy and may cause complications such as preterm labor (PTL). This study was aimed to investigate the effect of the vitamin D-binding protein (VDBP) rs7041 genotype, which has a significant effect on vitamin D metabolism and PTL. METHODS: This cross-sectional study was conducted with 32 pregnant women who had spontaneous PTL and 54 pregnant women who had no specific findings as a control group. Serum total vitamin D 25-hydroxy vitamin D (25(OH)D) levels were measured using the Elecsys Vitamin D Total Kit. VDBP was measured using a VDBP Quantikine ELISA Kit. The levels of bioavailable 25(OH)D were calculated based on the total 25(OH)D and VDBP concentrations. DNA was extracted using the DNeasy Blood and Tissue Kit. Single nucleotide polymorphisms (rs7041) in GC were analyzed using a TaqMan SNP Genotyping Assay Kit. The unpaired t-test, Chi-squared, and ANCOVA tests were performed. Firth's penalized logistic regression was applied. The area under the curve (AUC) was calculated and the cutoff value was determined. All statistical analyses were performed using R version 4.0.3 (R Foundation for Statistical Computing, Vienna, Austria). RESULTS: Total 25(OH)D levels were not significantly different between the two groups. Bioavailable 25(OH)D was significantly decreased in PTL women (p= .011), and VDBP was significantly increased in PTL women (p= .004) compared to the controls. Bioavailable 25(OH)D was lower in women with GT/TG and TT rs7041 genotypes than in those with GG, with statistical significance in women with the TT allele (p= .048). VDBP was higher in women with GT/TG and TT than those with GG, but there was no statistical significance. In PTL prevalence, bioavailable 25(OH)D and VDBP, the odds ratio increased by 1.463 times in GT/TG (p= .728) and increased by 1.675 times in TT compared to the GG allele (p= .640). In receiver operating characteristic (ROC) analysis for bioavailable 25(OH)D and VDBP, the AUC was 0.665 and 0685, respectively. The optimum cutoff of bioavailable 25(OH)D and VDBP levels for the diagnosis of PTL was calculated as 0.6 ng/mL and 523 µg/mL, respectively. CONCLUSIONS: Pregnant women with the VDBP rs7041(c.1296 T > G) T allele genotype had reduced serum levels of bioavailable 25(OH)D and were more likely to develop PTL. Therefore, if the T allele is found in the VDBP rs7041 SNP genotyping test before or during pregnancy, more careful prenatal care may be required because of the increased risk of PTL.

BACKGROUND: This randomized clinical trial was performed to compare pain scales between intravenous patient-controlled analgesia (IV-PCA) and patient-controlled epidural analgesia (PCEA) in patients undergoing open surgical resection of major pancreatobiliary malignancies. METHODS: One hundred ten patients were randomly assigned to the PCEA or IV-PCA group. We compared the numeric rating scale pain score during ambulation on postoperative day (PD) 2 and at rest (at 06:00, 12:00, and 18:00) from PD 1 to 7, the serum level of troponin I on PD 1, and the incidence of postoperative complications between the two groups. RESULTS: There were no significant differences in the pain scores during ambulation on PD 2, at rest up to PD 7, serum troponin I level, and postoperative complication rates. The incidences of nausea (20.4% vs. 6.3%; p = 0.039) and drowsiness (20.4% vs. 0%; p = 0.001) were higher in the IV-PCA group and the rate of dysuria (0% vs. 14.6%; p = 0.004) was higher in the PCEA group. CONCLUSION: PCEA showed no superiority over IV-PCA in terms of postoperative pain relief or morbidity after major open surgery for pancreatobiliary malignancies. The method of analgesia should be considered based the characteristics of the patient, surgeon, anesthesiologist, and institute.

ABSTRACT: The purpose of this study was to investigate the status of bone health in women working in agriculture and analyze the associations between bone health and various vitamin D-related biomarkers.This observational study enrolled women working in agriculture (nâ=â210) and control occupations (nâ=â180). The concentration of serum total 25-hydroxy vitamin D [25(OH)D] was measured using the Elecsys Vitamin D Total Kit, and serum vitamin D-binding protein (VDBP) was measured by enzyme-linked immunosorbent assay. Along with albumin, 25(OH)D and VDBP were used to calculate the concentrations of bioavailable and free 25(OH)D. Bone mineral density (BMD) and T-score were measured at lumbar 1 to 4 and the femur neck using dual-energy X-ray absorptiometry. To identify factors affecting BMD, log-linear model and linear regression analysis were performed for statistical analysis.Agricultural women workers showed higher serum concentrations of bioavailable 25(OH)D (12.8â±â3.7 vs 8.7â±â5.1âng/mL) and lower VDBP concentrations (201.8â±â45.0 vs 216.0â±â68.2âµg/mL) than control women. The association between these 2 vitamin D related-biomarkers and femur neck BMD were confirmed through univariable and multivariable linear model analysis. Although lumbar BMD did not differ between groups, the agricultural group displayed a lower femur BMD and a 4.3-fold increase in the risk of osteoporosis compared with the control group.Women working in agriculture showed lower femur BMD than the control group. Of the vitamin D-related biomarkers tested, bioavailable 25(OH)D and VDBP were associated with BMD. As bioavailable 25(OH)D levels are affected mainly by VDBP levels, VDBP may play a role in the lower femur neck BMD values observed in the agricultural group. Thus, the measurement of VDBP concentration might be considered a simple and non-invasive method for measuring bone health status.

Background and Objectives: This study aimed to investigate whether mild fetal tricuspid regurgitation (TR) at 11+ 0 to 13+ 6 weeks of gestation affects perinatal outcomes. Since fetal right ventricular load is associated with placental resistance, we hypothesized that fetal mild TR would be associated with perinatal outcomes as a consequence of abnormal placentation. Materials and Methods: We retrospectively evaluated 435 women with first-trimester scan data. Blood flow across the tricuspid valve was examined in singleton pregnancies between 11+ 0 and 13+ 6 weeks of gestation. Women were categorized according to the presence or absence of fetal mild TR, and the maternal and pregnancy characteristics and perinatal outcomes were compared. Multiple linear and logistic regression analyses were conducted to identify independent predictors of perinatal outcome. Results: In the group with mild TR, there were more cases of borderline amniotic fluid index, including oligohydramnios (p = 0.031), and gestational age- and sex-specific birth weights were lower (p = 0.012). There were no significant differences in other perinatal outcomes, including preeclampsia, gestational hypertension and small for gestational age. Gestational diabetes (adjusted odds ratio (OR) 0.514, 95% confidence interval (CI) 0.312-0.947) and fetal mild TR (adjusted OR 1.602, 95% CI 1.080-2.384) were identified as factors associated with below borderline amniotic fluid index before birth. The factors that affected gestational age and sex-specific birth weight were also gestational diabetes (adjusted beta coefficient 9.673, p = 0.008) and the presence of fetal mild TR (adjusted beta coefficient -6.593, p = 0.007). Conclusions: Mild fetal TR observed in the first trimester is negatively associated with fetal growth and the amniotic fluid index at term but not with other adverse pregnancy or perinatal outcomes due to abnormal placentation.

OBJECTIVE: Vitamin D-binding protein (VDBP) mediates various biological processes in humans. The goal of this study was to investigate whether VDBP gene polymorphisms could predispose Korean women to endometriosis. METHODS: We prospectively enrolled women with endometriosis (n = 16) and healthy controls (n = 16). Total serum 25-hydroxyl vitamin D (25(OH)D) concentrations were measured using an Elecsys vitamin D total kit. Levels of bioavailable and free 25(OH)D were calculated. Concentrations of VDBP were measured using a vitamin D BP Quantikine ELISA kit. DNA was extracted using a DNeasy blood & tissue kit. Two singlenucleotide polymorphisms (SNPs; rs4588 and rs7041) in GC, the gene that codes for VDBP, were analyzed using a TaqMan SNP genotyping assay kit. The functional variant of VDBP was determined based on the results of the two SNPs. RESULTS: Gravidity and parity were significantly lower in the endometriosis patients than in the control group, but serum CA-125 levels and the erythrocyte sedimentation rate were significantly higher. Total serum 25(OH)D levels in the endometriosis patients were significantly lower than in the control group. However, serum bioavailable 25(OH)D, free 25(OH)D, and VDBP levels did not differ significantly between the endometriosis and control groups. The genotypes and allele frequencies of GC were similar in both groups. CONCLUSION: Korean women with endometriosis had lower total serum 25(OH)D concentrations than controls. Neither serum VDBP concentrations nor polymorphisms in the gene coding for VDBP were associated with endometriosis. Further studies are needed to investigate the pathophysiology and clinical implications of 25(OH)D and VDBP in endometriosis.
ABSTRACT
OBJECTIVE: To investigate serum 25-hydroxyl vitamin D (25(OH)D) and vitamin D-binding protein (VDBP) concentrations in women with endometriosis according to the severity of disease. METHODS: Women with mild endometriosis (n = 9) and advanced endometriosis (n = 7), as well as healthy controls (n = 16), were enrolled in this observational study. Serum total 25(OH)D concentrations were analyzed using the Elecsys vitamin D total kit with the Cobas e602 module. Concentrations of bioavailable and free 25(OH)D were calculated. Concentrations of VDBP were measured using the Human Vitamin D BP Quantikine ELISA kit. Variables were tested for normality and homoscedasticity using the Shapiro-Wilk test and Leven F test, respectively. Correlation analysis was used to identify the variables related to total 25(OH)D and VDBP levels. To assess the effects of total 25(OH)D and VDBP levels in the three groups, multivariate generalized additive modeling (GAM) was performed. RESULTS: Gravidity and parity were significantly different across the three groups. Erythrocyte sedimentation rate (ESR) and CA-125 levels increased as a function of endometriosis severity, respectively (p= 0.051, p= 0.004). The correlation analysis showed that total 25(OH)D levels were positively correlated with gravidity (r = 0.59, p< 0.001) and parity (r = 0.51, p< 0.003). Multivariate GAM showed no significant relationship of total 25(OH)D levels with EMT severity after adjusting for gravidity and ESR. However, the coefficient of total 25(OH)D levels with gravidity was significant (1.87; 95% confidence interval, 0.12-3.63; p= 0.040). CONCLUSION: These results indicate that vitamin D and VDBP levels were not associated with the severity of endometriosis.
ABSTRACT
OBJECTIVE: The favored method of preserving fertility in young female cancer survivors is cryopreservation and autotransplantation of ovarian tissue. Reducing hypoxia until angiogenesis takes place is essential for the survival of transplanted ovarian tissue. The aim of this study was to investigate the role of angiopoietin-1 (Angpt-1), angiopoietin-2 (Angpt-2), and vascular endothelial growth factor (VEGF) in ovarian tissue grafts that were cryopreserved using two methods. METHODS: Ovarian tissues harvested from ICR mice were divided into three groups: group I (control), no cryopreservation; group II, vitrification in EFS (ethylene-glycol, ficoll, and sucrose solution)-40; and group III, slow freezing in dimethyl sulfoxide. We extracted mRNA for VEGF, Angpt-1, and Angpt-2 from ovarian tissue 1 week following cryopreservation and again 2 weeks after autotransplantation. We used reverse transcriptase-polymerase chain reaction to quantify the levels of VEGF, Angpt-1, and Angpt-2 in the tissue. RESULTS: Angpt-1 and Angpt-2 expression decreased after cryopreservation in groups II and III. After autotransplantation, Angpt-1 and Angpt-2 expression in ovarian tissue showed different trends. Angpt-1 expression in groups II and III was lower than in group I, but Angpt-2 in groups II and III showed no significant difference from group I. The vitrified ovarian tissues had higher expression of VEGF and Angpt-2 than the slowfrozen ovarian tissues, but the difference was not statistically significant. CONCLUSION: Our results indicate that Angpt-2 may play an important role in ovarian tissue transplantation after cryopreservation although further studies are needed to understand its exact function.
ABSTRACT
PURPOSE: Even though the therapeutic gold standard of hilar cholangiocarcinoma (HCCA) resection is cancer-free resection margin (RM), surgical treatment still remains challenging. This study evaluated the prognostic significance of RM status in resected HCCA patients and identified survival prognostic factors. MATERIALS AND METHODS: We reviewed records of 96 HCCA patients who underwent surgery from 2001 to 2012 and analyzed the RM status and prognostic factors that affecting survival. RESULTS: Negative RM (n=31, 33%) was significantly associated with better survival vs. positive RM (n=65, 67%) (mean survival time [MST], 33 months vs. 21 months; p=0.011). Margins with histological findings of non-dysplastic epithelium, low-grade dysplasia, and carcinoma in situ were not associated with survival differences (MST, 33 months vs. 33 months vs. 30 months; p=0.452), whereas positive margins were associated with poorer survival relative to carcinoma in situ (MST, 30 months vs. 21 months; p=0.050). Among patients with R0 resection, narrow (≤ 5 mm) and wide (> 5 mm) margins were not associated with survival differences (MST, 33 months vs. 30 months; p=0.234). Although positive proximal RM was associated with poorer survival compared to negative RM (MST, 19 vs. 33; p=0.002), no survival difference was observed between positive and negative distal RMs (MST, 30 vs. 33; p=0.628). Proximal RM positivity (hazard ratio [HR], 2.688; p=0.007) and nodal involvement (HR, 3.293; p < 0.001) were independent survival prognostic factors. CONCLUSION: A clear RM, especially proximal RM status, was significant prognosticator, and proximal bile duct resection to the greatest technically feasible extent may be necessary, with careful consideration of the potential morbidity and oncologic outcomes after resection. However, an aggressive approach to obtain a negative distal RM might be controversial and should be considered carefully, depending on the patient's status.

BACKGROUND: Although laparoscopic colorectal surgery decreases postoperative pain and facilitates a speedier recovery compared with laparotomy, postoperative pain at trocar insertion sites remains a clinical concern. The objective of this study was to assess the effects of a preoperative ultrasound-guided transversus abdominis plane (TAP) block on pain after laparoscopic surgery for colorectal cancer. METHODS: In total, 58 patients scheduled to undergo laparoscopic surgery following a diagnosis of colorectal cancer were included in this study. The patients were randomized into TAP and control groups; the TAP group patients received a preoperative ultrasound-guided bilateral TAP block with 0.5 mL/kg of 0.25 % bupivacaine, while the control patients received the block with an equal amount of saline. Pain on coughing and at rest was assessed during postanesthetic recovery (PAR; 1 h after surgery) and on postoperative days (PODs) 1 (24 h), 2 (48 h), and 3 (72 h) by an investigator blinded to group allocations using the numeric rating scale (NRS). The primary outcome was pain on coughing on postoperative day (POD) 1. RESULTS: Fifty-five patients were included in the final analysis, including 28 in the TAP and 27 in the control groups. The pain intensity on coughing and at rest during PAR and on PODs 1, 2, and 3 showed no significant differences between groups. Furthermore, there was no significant difference in postoperative opioid consumption, sedation scores, nausea scores at the four time points, complication rates, and length of hospital stay between groups. CONCLUSIONS: In colorectal cancer patients undergoing laparoscopic colorectal surgery, a TAP block did not offer enough benefit for clinical efficacy in terms of postoperative pain or analgesic consumption.

BACKGROUND AND AIM: The improvements in surgical technique and perioperative management in the recent decades may warrant revisit for survival outcomes and prognostic factors after liver resection for hepatocellular carcinoma (HCC). This study aimed to analyze the survival outcomes after liver resection for HCC for a consecutive cohort of 1002 patients. METHODS: This study was performed by analyzing the clinicopathological and follow-up data of 1002 consecutive patients who underwent liver resection for HCC from April 2001 to December 2013. Prognostic factors were investigated by univariate and multivariate analysis, using the Cox's proportional hazards model. RESULTS: The overall incidence of postoperative complications was 16.1% (n = 161), with an in-hospital mortality rate of 0.3% (n = 3). The rates of 1-, 3-, and 5-year overall survival were 91.9%, 78.9%, and 69.5%, while the rates of 1-, 3-, and 5-year recurrence-free survival were 71.7%, 51.7%, and 43.7%, respectively. Multivariate analysis showed that patient age, platelet count, intraoperative estimated blood loss (EBL), tumor number, Edmond-Steiner grade, microvascular invasion, major vessel invasion, and intrahepatic metastasis were independent significant prognostic factors affecting the overall survival. Platelet count, intraoperative EBL, maximal tumor size, major vessel invasion, capsule formation, intrahepatic metastasis, cirrhosis, and the pathological stage were independent prognostic factors for recurrence-free survival. CONCLUSIONS: Survival of patients with HCC after resection should be stratified by various perioperative clinicopathological factors. Platelet count and intraoperative EBL could be considered as one of the powerful predictors of the prognosis and recurrence of HCC in such patients.

We describe 2 cases of patients with loss of hepatic arterial flow during surgery for pancreatic head cancer due to celiac stenosis caused by median arcuate ligament compression. The first case underwent pylorus-resecting pancreatoduodenectomy for pancreatic head cancer. After resection of the gastroduodenal artery, flow in the common hepatic artery disappeared, and celiac axis stenosis was identified. Interventional stent insertion was attempted, however, it failed due to the acute angle of the celiac orifice (os). This problem was resolved by arterial reconstruction. The second case underwent pylorus-preserving pancreatoduodenectomy for pancreatic head cancer and the same phenomenon occurred during the procedure. Interventional stent insertion was also tried; in this patient, however, it failed due to the acute angle of the celiac os. The problem was resolved by changing a femoral approach to a brachial approach, and the stent was inserted into the celiac os successfully.
ABSTRACT
AIM: To investigate the impact of high-dose hepatitis B immunoglobulin (HBIG) on hepatocellular carcinoma (HCC) and hepatitis B virus (HBV) recurrence and overall survival after living donor liver transplantation (LDLT). METHODS: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen (HBeAg) -positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group. Using the propensity score 1:1 matching method, 38 and 18 pairs were defined as adhering to and not adhering to the Milan criteria. For each pair, HCC recurrence, HBV recurrence and overall survival were analyzed by the Kaplan-Meier method and the log rank test according to the HBIG dose. RESULTS: Among those who met the Milan criteria, the 6-mo, 1-year, and 3-year HCC recurrence-free survival rates were 88.9%, 83.2%, and 83.2% in the low-dose HBIG group and 97.2%, 97.2%, and 97.2% in the high-dose HBIG group, respectively (P = 0.042). In contrast, among those who did not meet the Milan criteria, HCC recurrence did not differ according to the HBIG dose (P = 0.937). Moreover, HBV recurrence and overall survival did not differ according to the HBIG dose among those who met (P = 0.317 and 0.190, respectively) and did not meet (P = 0.350 and 0.987, respectively) the Milan criteria. CONCLUSION: High-dose HBIG therapy can reduce HCC recurrence in HBV-DNA/HBeAg-positive patients after LDLT.

Iatrogenic parasitic myomas are rare. The condition is defined by the presence of multiple smooth-muscle tumorous nodules in the peritoneal cavity. This may be attributable to seeding of myoma particles during uterine surgery. The clinical course is usually indolent. The disease is often asymptomatic and is usually discovered only incidentally. A 38-year-old woman who had undergone abdominal myomectomy 7 months prior presented with acute abdominal pain and a huge pelvic mass. We performed exploratory laparotomy. A parasitic mass 17 cm in diameter with a twisted omental pedicle was identified. En bloc excision of the mass and omentum was performed, followed by total abdominal hysterectomy. Histopathological examination of multiple sections revealed features compatible with an infarcted leiomyoma. Thus, we present a very rare case of an iatrogenic, rapidly growing parasitic myoma complicated by omental torsion (which caused the acute abdominal pain). We also offer a literature review.
ABSTRACT
OBJECTIVE: Revascularization is critical for successful ovarian tissue transplantation. Vascular endothelial growth factor (VEGF) and angiopoietin-2 (angpt-2) are the principal mediators of neovascularization. This study was designed to assess VEGF and angpt-2 levels in cryopreserved ovarian tissue after heterotopic autotransplantation. METHODS: Ovarian tissues harvested from ICR mice at 5 to 6 weeks of age were stratified as follows: no cryopreservation (controls, group I); vitrification in VFS-40 (vitrification, group II); and gradual freezing in dimethyl sulfoxide (slow-freezing, group III). Frozen specimens were thawed at room temperature, assaying VEGF and angpt-2 levels 1 week after cryopreservation and 2 weeks after autotransplantation. RESULTS: VEGF and angpt-2 protein levels were significantly lower in cryopreserved ovaries of groups II and III than in controls (group I, P<0.05), whereas groups II and III did not differ significantly in this regard. After autotransplantation of cryopreserved ovarian tissue, VEGF and angpt-2 protein levels did not differ significantly by technique but tended to be lower than corresponding levels in controls. CONCLUSION: Expression of angiogenic factors in ovarian tissue is thought to vary by method of cryopreservation. Our findings indicate that levels of angiogenic factors expressed in cryopreserved ovarian tissue after autotransplantation do not differ appreciably from control levels, regardless of cryopreservation technique.
ABSTRACT
OBJECTIVE: This study aimed to examine clinical practice patterns in the management of pregnant women admitted with threatened preterm labor (TPL) in Korea. METHODS: Data from women admitted with a diagnosis of TPL were collected from 22 hospitals. TPL was defined as regular uterine contractions with or without other symptoms such as pelvic pressure, backache, increased vaginal discharge, menstrual-like cramps, bleeding/show and cervical changes. Data on general patient information, clinical characteristics at admission, use of tocolytics, antibiotics, and corticosteroids, and pregnancy outcomes were collected using an online data collections system. RESULTS: A total of 947 women with TPL were enrolled. First-line tocolysis was administered to 822 (86.8%) patients. As a first-line tocolysis, beta-agonists were used most frequently (510/822, 62.0%), followed by magnesium sulfate (183/822, 22.3%), calcium channel blockers (91/822, 11.1%), and atosiban (38/822, 4.6%). Of the 822 women with first-line tocolysis, second-line tocolysis were required in 364 (44.3%). Of 364 with second-line, 199 had third-line tocolysis (37.4%). Antibiotics were administered to 29.9% of patients (284/947) with single (215, 22.7%), dual (26, 2.7%), and triple combinations (43, 4.5%). Corticosteroids were administered to 420 (44.4%) patients. Betamethasone was administered to 298 patients (71.0%), and dexamethasone was administered to 122 patients (29.0%). CONCLUSION: Practice patterns in the management of TPL in Korea were quite various. It is needed to develop standardized practice guidelines for TPL management.
ABSTRACT
BACKGROUND: Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is a rare subtype of primary liver cancer consisting of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). Because of the rarity of this tumor, its feature is poorly understood. The present study aimed to evaluate the clinicopathological features and long-term prognosis of patients with cHCC-CC after surgery and to compare with those of the patients with stage-matched HCC and CC. METHODS: The clinicopathological features of the patients who underwent surgery for cHCC-CC at our center during the period of 2001-2010 were retrospectively analyzed and compared with those of stage-matched HCC and CC patients. Cancer staging was performed according to the AJCC Cancer Staging Manual (6th ed.). Overall survival and disease-free survival were compared among the groups and prognostic factors of cHCC-CC were evaluated. RESULTS: Significant differences were observed in clinicopathological features among 42 patients with cHCC-CC, 90 patients with HCC and 45 patients with CC. Similar to HCC patients, cHCC-CC patients had frequent hepatitis B virus antigen positivity, microscopic vessel invasion, cirrhosis and high level of serum alpha-fetoprotein. Similar to CC patients, cHCC-CC patients showed increased bile duct invasion and decreased capsule. The 1-, 3-, and 5-year overall survival and disease-free survival of patients with cHCC-CC were not significantly different from those with stage-matched patients with CC; but significantly poorer than those with HCC. In subanalysis of patients with stage II, the overall survival in patients with cHCC-CC or CC was significantly poorer than that in patients with HCC. We did not find the difference in patients with other stages. Univariate analysis of overall and disease-free survival of patients with cHCC-CC showed that the vascular invasion and intrahepatic metastasis were the significant predictive factors. CONCLUSION: Patients with cHCC-CC showed similar clinicopathological features as those with HCC or CC, and patients with cHCC-CC or CC had a poorer prognosis compared with those with HCC, especially at matched stage II.

BACKGROUND: Preoperative absolute monocyte count in peripheral blood (AMCPB) is closely associated with prognoses in not only various malignancies but also hepatocellular carcinoma (HCC). The purpose of this study was to evaluate whether pretransplant AMCPB predicts posttransplant outcomes in patients with HCC undergoing liver transplantation (LT). METHOD: We retrospectively analyzed relationships between clinicopathologic factors involving pretransplant AMCPB and tumor recurrence or survival in 256 patients who had undergone LT for HCC between January 2005 and April 2012. RESULTS: ROC curve analysis showed that AMCPB >200/mm(3) was a risk factor for tumor recurrence; 43 patients showed higher AMCPB (>200/mm(3)), whereas 213 showed lower AMCPB (≤200/mm(3)) at the time of LT. On multivariate analysis, pretransplant high AMCPB, positive findings in pretransplant (18)F-FDG PET/CT, pathological maximal tumor size >5 cm, intrahepatic metastasis, moderately or poorly differentiated tumor and microvascular invasion were independent factors affecting recurrence-free survival. When we performed subgroup analysis based on the Milan criteria, high AMCPB was an independent factor for predicting HCC recurrence in patients with tumor beyond the Milan criteria (P=0.004), and not for patients within the criteria. CONCLUSION: This study demonstrated that pretransplant AMCPB could predict tumor recurrence after LT for HCC, especially in patients with tumor beyond the Milan criteria.

BACKGROUND: Leukocyte subsets in peripheral blood, which include neutrophils, lymphocytes, and monocytes, have not been well established as prognostic factors in patients with hepatocellular carcinoma (HCC). METHODS: Consecutive patients who underwent curative hepatic resection for HCC at the National Cancer Center, Republic of Korea, from 2001 to 2008 were enrolled in this retrospective study. Clinicopathologic factors, cancer-specific survival (CSS), and disease-free survival (DFS) were analyzed with respect to preoperative lymphocyte subsets, especially monocyte ratio. RESULTS: The 603 patients had a median follow-up of 40.0 months and a 5-year overall survival rate of 67.7 %. In univariate analysis of survivals, preoperative lymphocyte ratio ≤35 % and monocyte ratio >7 % were significantly poor prognostic factors. In multivariate analysis, preoperative monocyte ratio >7 %, satellite nodule, and microvascular invasion were independent risk factors for CSS and DFS (hazard ratio of monocyte ratio >7 % = 1.77, p = 0.02 and 1.57, p = 0.006, respectively). Considering monocyte ratio with preoperative α-fetoprotein level, patients with both abnormal α-fetoprotein levels (>12 ng/mL) and monocyte ratio >7 % showed significantly worse CSS and DFS than other groups (p < 0.001). Cirrhotic patients with monocyte ratio >7 % showed significantly poor CSS and DFS compared with non-cirrhotic patients (p = 0.033 and <0.001, respectively). CONCLUSIONS: A preoperative monocyte ratio >7 % of peripheral blood is an independent risk factor for CSS and DFS after hepatic resection for HCC. Preoperative monocyte ratio might be considered as a novel biomarker for HCC.
