Abstract
Periodic mammography and/or sonography examinations are conducted across numerous hospitals nationalwidely, especially for antedees with a positive mammography screening. Despite the regular practice, clinical efficacy of hospital-based breast cancer surveillance remains unclear. Specifically, the impact of surveillance interval upon survival and prognostic surrogates stratified by menopausal status, as well as malignant transition rate should be deciphered. We retrieved cancer registry to ascertain 841 breast cancers with surveillance history through administration data. Healthy controls underwent breast surveillance and were concurrently free of cancer. More benign diseases rather than cancers were identified from premenopausal women (age ≤50 years) with sonography alone within one year, as well as older women (age >50) with both mammography and sonography one to two years before a cancer or benign diagnosis. Among breast cancers, mammography alone during the antecedent one to two years had a protective effect for diagnosing carcinoma in situ rather than invasive cancer (age-adjusted odds ratio: 0.048, P = 0.016). Three-state time homogeneous Markov model showed that hospital-based breast surveillance within 2 years of disease onset reduced the malignant transition rate by 65.16% (59.79-76.74%). The clinical efficacy of breast cancer surveillance was evidenced.

Abstract
PURPOSE To test the efficacy of a self-management program based on acceptance and commitment therapy on quality of life, emotional distress, fatigue, physical activity, and fruit and vegetable intake in patients with colorectal cancer. METHODS The study was a randomized controlled trial. A sample of 156 patients with colorectal cancer (stage I-III) was recruited by convenience sampling and participants were allocated randomly assigned to control or intervention groups. The intervention included a colorectal cancer self-management information booklet, two personal skills training sessions, and 12 follow-up telephone calls. The control group received health education leaflets. Outcome variables were assessed in both groups at baseline and every two months thereafter during the six-month follow-up period. RESULT The mean age of participants was 62 years (range: 30-89 years). Generalized estimation equations analyses revealed significant differences over time in changes in anxiety (β = -2.22, p = 0.001), depression (β = -1.48, p = 0.033), fatigue (β = 4.46, p = 0.001), physical and functional measures (β = 6.16, p = 0.005), and colorectal-cancer-specific quality of life (β = 7.45, p = 0.012). However, there were no significant differences in changes in physical activity or fruit and vegetable intake over time. CONCLUSION The self-management skills provided by oncology nurses, including symptom management, psychological adjustment, and relaxation exercises, help colorectal cancer patients to overcome the challenges of cancer survivorship, accelerate their recovery, and improve their quality of life. THE TRIAL NUMBER NCT03853278 registered on ClinicalTrials.gov.

Abstract
PURPOSE/OBJECTIVE(S) CDK4/6 inhibitors combined with endocrine therapy are demonstrated to prolong survival for hormone receptor (HR)-positive and HER2-negative advanced breast cancer. We sought to assess whether cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors can enhance the radiosensitivity and their underlying mechanisms in this subtype of breast cancer through both in vitro and in vivo approaches. MATERIALS/METHODS We used MCF-7 and T-47D (HR-positive and HER2-negative) breast cancer cell lines, and different doses of CDK4/6 inhibitors (ribociclib and palbociclib) and radiotherapy (RT) to assess the biological functions and mechanisms through in vitro study. The radiation enhancing effect was assessed by clonogenic assay, numbers of the DNA damage response-related molecules, γH2AX and 53BP1, were assessed by immunofluorescence. The p-ERK, c-Myc, and DNA-double strand break (DNA-DSB)-related molecules, p-DNA-PKcs, and p-ATM, were assessed by western blotting. We used NF-κB p65 Transcription Factor Assay Kit to evaluate the transcriptional activity of NF-κB. We evaluated the antitumor effect of combined RT (2 Gy every other day for total 6 Gy) and ribociclib through the MCF-7 orthotopic xenograft model. RESULTS The synergistic effects of combining RT with different concentrations of ribociclib and palbociclib pretreatment were demonstrated by colonogenic assay. We revealed that CDK4/6 inhibitors synergistically increased the numbers of RT-induced γH2AX and 53BP1, downregulated the expression of p-DNA-PKcs and p-ATM activated by RT, and diminished the expression of RT-triggering p-ERK expression, and NF-κB activation and its down-streaming gene, c-Myc. When compared with control, ribociclib, and RT group, combined ribociclib and RT significantly shrunk the tumor growth of MCF-7 cell xenograft tumors, and downregulated the immunohistochemical expression of p-ERK, p-NF-κB p65, and c-Myc than control group. CONCLUSION Our results demonstrated that combining CDK4/6 inhibitors enhanced the radiosensitivity in HR-positive and HER2-negative breast cancer cells, and conceivably radioenhancing mechanisms of CDK4/6 inhibitors are at least through lessening DNA-DSB repairing processes and weakening the activation of ERK signaling and NF-κB signaling by RT.

Abstract
BACKGROUND Hernia repair is one of the most common surgical procedures; however, the long-term outcomes are seldom reported due to incomplete follow-up. OBJECTIVE The aim of this study was to examine the use of a mobile app for the long-term follow-up of hernia recurrence, complication, and quality-of-life perception. METHODS A cloud-based corroborative system drove a mobile app with the HERQL (Hernia-Specific Quality-of-Life) questionnaire built in. Patients who underwent hernia repair were identified from medical records, and an invitation to participate in this study was sent through the post. RESULTS The response rate was 11.89% (311/2615) during the 1-year study period, whereas the recurrence rate was 1.0% (3/311). Causal relationships between symptomatic and functional domains of the HERQL questionnaire were indicated by satisfactory model fit indices and significant regression coefficients derived from structural equational modeling. Regarding patients' last hernia surgeries, 88.7% (276/311) of the patients reported them to be satisfactory or very satisfactory, 68.5% (213/311) of patients reported no discomfort, and 61.1% (190/311) of patients never experienced mesh foreign body sensation. Subgroup analysis for the most commonly used mesh repairs found that mesh plug repair inevitably resulted in worse symptoms and quality-of-life perception from the group with groin hernias. CONCLUSIONS The mobile app has the potential to enhance the quality of care for patients with hernia and facilitate outcomes research with more complete follow-up.

Abstract
Objective: To explore the clinical characteristics, prognostic risk factors and effective treatment of severe hemophagocytic syndrome (HPS) in children, so as to provide reference for the clinical diagnosis and treatment of the disease. Methods: The clinical data of 83 children with severe HPS admitted in Affiliated Hospital of Zunyi Medical University from January 2014 to April 2021 were collected, and their clinical characteristics, prognosis and prognostic risk factors were analyzed. The children were divided into central nervous system (CNS) dysfunction group and non-CNS dysfunction group according to whether they were accompanied with CNS dysfunction, and were divided into blood purification group and non-blood purification group according to whether they received blood purification, then the survival differences were compared. Results: Among the 83 children, there were 43 males and 40 females, aged[M(Q1,Q3)] 36(15,27)months. A total of 51 children were induced by infection, among which 41 children (80.4%) were infected with EB virus. All the children were accompanied by multiple organ dysfunction (MODS), and dysfunction of the blood system (72.3%), liver (71.1%), respiratory system (53.0%) and CNS (37.3%) were common. By the end of follow-up, 40 cases (48.2%) survived, 38 cases (45.8%) died, and 5 cases (6.0%) were lost to follow-up. CNS dysfunction was a risk factor (HR=3.358, 95%CI: 1.445-7.803, P=0.005) and blood purification was a protective factor (HR=0.362, 95%CI: 0.179-0.730, P=0.005) affecting the prognosis of children. The mortality of CNS dysfunction group was statistically higher than that of non-CNS dysfunction group (74.2% vs 28.8%) (P<0.001); The mortality of blood purification group was statistically lower than that of non-blood purification group (31.0% vs 61.0%) (P=0.010). Conclusions: Severe HPS in children was dangerous and had a poor overall prognosis. CNS dysfunction was a risk factor for death. Blood purification could significantly improve the prognosis and improve the survival rate of children.

Abstract
Background The aim of the study was to enhance colorectal cancer prognostication by integrating single nucleotide polymorphism (SNP) and gene expression (GE) microarrays for genomic and transcriptional alteration detection; genes with concurrent gains and losses were used to develop a prognostic signature. Methods The discovery dataset comprised 32 Taiwanese colorectal cancer patients, of which 31 were assayed for GE and copy number variations (CNVs) with Illumina Human HT-12 BeadChip v4.0 and Omni 25 BeadChip v1.1. Concurrent gains and losses were declared if coherent manners were observed between GE and SNP arrays. Concurrent genes were also identified in The Cancer Genome Atlas Project (TCGA) as the secondary discovery dataset (n = 345). Results The “universal” concurrent genes, which were the combination of z-transformed correlation coefficients, contained 4022 genes. Candidate genes were evaluated within each of the 10 public domain microarray datasets, and 1655 (2000 probe sets) were prognostic in at least one study. Consensus across all datasets was used to build a risk predictive model, while distinct relapse-free/overall survival patterns between defined risk groups were observed among four out of five training datasets. The predictive accuracy of recurrence, metastasis, or death was between 61 and 86% (cross-validation area under the receiver operating characteristic (ROC) curve: 0.548-0.833) from five independent validation studies. Conclusion The colorectal cancer concurrent gene signature is prognostic in terms of recurrence, metastasis, or mortality among 1746 patients. Genes with coherent patterns between genomic and transcriptional contexts are more likely to provide prognostication for colorectal cancer.

Abstract
BACKGROUND/PURPOSE Previously we had identified concurrent genes, which highlighted the interplay between copy number variation (CNV) and differential gene expression (GE) for Han Chinese breast cancers. The merit of the approach is to discovery biomarkers not identifiable by conventional GE only data, for which phenotype-correlation or gene variability is the criteria of gene selection. MATERIALS AND METHODS Thirty-one comparative genomic hybridization (CGH) and 83 GE microarrays were performed, with 29 breast cancers assayed from both platforms. Potential targets were revealed by Genomic Identification of Significant Targets in Cancer (GISTIC) from CGH arrays. Concurrent genes and genes with significant GISTIC scores were used to derive the extended concurrent genes signature, which was consensus from leading edge analysis across all studies and a supervised partial least square (PLS) regression predictive model of disease-free survival was constructed. RESULTS There were 1584 concurrent genes from 29 samples with both CGH and GE microarrays. Enriched concurrent genes sets for disease-free survival were identified independently from 83 GE arrays and another one with Han Chinese origin as well as three studies of Western origin. For five studies with disease-free survival follow up, prognostic discrepancy was observed between predicted high-risk and low-risk group patients. CONCLUSION We concluded that through parallel analyses of CGH and GE microarrays, the proposed extended concurrent gene expression signature can identify biomarkers with prognostic values.

Abstract
BACKGROUND High-risk triple negative breast cancers (TNBC) are characterized by poor prognosis, rapid progression to metastatic stage and onset of resistance to chemotherapy, thus representing an area in need of new therapeutic approaches. PD-L1 expression is an adaptive mechanism of tumour resistance to tumour infiltrating lymphocytes, which in turn are needed for response to chemotherapy. Overall, available data support the concept that blockade of PD-L1/PD-1 check-point may improve efficacy of classical chemotherapy. PATIENTS AND METHODS Two-hundred-eighty patients with TNBC were enrolled in this multicentre study (NCT002620280) and randomized to neoadjuvant carboplatin AUC 2 and nab-paclitaxel 125 mg/m2 iv on days 1 and 8, without (N = 142) or with (N = 138) atezolizumab 1200 mg iv on day 1. Both regimens were given q3 weeks for 8 cycles before surgery and 4 cycles of an adjuvant anthracycline regimen. The primary aim of the study is to compare event-free survival, an important secondary aim was the rate of pathological complete remission (pCR defined as absence of invasive cells in breast and lymph nodes). The primary population for all efficacy endpoints is the intention-to-treat population. RESULTS The intention-to-treat analysis revealed that pCR rate after treatment with atezolizumab (48.6%) did not reach statistical significance compared to no atezolizumab [44.4%: odds ratio (OR) 1.18; 95% CI 0.74-1.89; P = 0.48]. Treatment-related adverse events were similar with either regimen except for a significantly higher overall incidence of serious adverse events and liver transaminases abnormalities with atezolizumab. CONCLUSIONS The addition of atezolizumab to nab-paclitaxel and carboplatin did not significantly increase the rate of pCR in women with TNBC. In multivariate analysis the presence of PD-L1 expression was the most significant factor influencing rate of pCR (OR 2.08). Continuing follow up for the event-free survival is ongoing, and molecular studies are under way.

Abstract
Pancreatic adenocarcinoma (PAC) is the 8th leading cause of cancer-related deaths in Taiwan, and its incidence is increasing. The development of PAC involves successive accumulation of multiple genetic alterations. Understanding the molecular pathogenesis and heterogeneity of PAC may facilitate personalized treatment for PAC and identify therapeutic agents. We performed tumor-only next-generation sequencing (NGS) with targeted panels to explore the molecular changes underlying PAC patients in Taiwan. The Ion Torrent Oncomine Comprehensive Panel (OCP) was used for PAC metastatic lesions, and more PAC samples were sequenced with the Ion AmpliSeq Cancer Hot Spot (CHP) v2 panel. Five formalin-fixed paraffin-embedded (FFPE) metastatic PAC specimens were successfully assayed with OCP, and KRAS was the most prevalent alteration, which might contraindicate the use of anti-EGFR therapy. One PAC patient harbored a FGFR2 p. C382R mutation, which might benefit from FGFR tyrosine kinase inhibitors. An additional 38 samples assayed with CHP v2 showed 100 hotspot variants, collapsing to 54 COSMID IDs. The most frequently mutated genes were TP53, KRAS, and PDGFRA (29, 23, 10 hotspot variants), impacting 11, 23, and 10 PAC patients. Highly pathogenic variants, including COSM22413 (PDGFRA, FATHMM predicted score: 0.88), COSM520, COSM521, and COSM518 (KRAS, FATHMM predicted score: 0.98), were reported. By using NGS with targeted panels, somatic mutations with therapeutic potential were identified. The combination of clinical and genetic information is useful for decision making and precise selection of targeted medicine.

Abstract
Simple Summary Although the incidence of thyroid cancer is increasing, improvements in treatment have resulted in more patients being confirmed to have a second primary cancer. However, studies on potential biomarkers for predicting the risk of second primary malignancy are extremely limited. Therefore, our objective was to establish molecular biomarkers for the risk prediction of second primary malignancy using routinely collected formalin-fixed paraffin-embedded tissue specimens. Our results suggest that the deficient mismatch repair phenotype, the expression of pRb, and the lack of CDK4 or CDK6 are significantly associated with co-occurrence of nonthyroid malignancy. The predictive value of these immunohistochemical profiles for the co-occurrence of nonthyroid malignancy was also assessed. The combined evaluation of a four-biomarker signature model may provide the most important predictive innovation. Our study proposes the first tissue-based screening tool for risk stratification and further active surveillance in patients with thyroid cancer. Abstract Some patients with thyroid cancer develop a second primary cancer. Defining the characteristics of patients with double primary cancers (DPCs) is crucial and needs to be followed. In this study, we examine molecular profiles in DPC. We enrolled 71 patients who received thyroid cancer surgery, 26 with single thyroid cancer (STC), and 45 with DPC. A retrograde cohort was used to develop immunohistochemical expressions of mismatch repair (MMR) proteins and cell-cycle-related markers from tissue microarrays to produce an equation for predicting the occurrence of DPC. The multivariate logistic model of 67 randomly selected patients (24 with STC and 43 with DPC) identified that the expression of deficient MMR (dMMR) (odds ratio (OR), 10.34; 95% confidence interval (CI), 2.17–49.21) and pRb (OR, 62.71; 95% CI, 4.83–814.22) were significantly associated with a higher risk of DPC. In contrast, the expression of CDK4 (OR, 0.19; 95% CI, 0.04–0.99) and CDK6 (OR, 0.03; 95% CI, 0.002–0.44) was significantly associated with a lower risk of DPC. Collectively, dMMR, pRb, CDK4, and CDK6 have a sensitivity of 88.9% (95% CI, 75.1–95.8) and a specificity of 69.2% (95% CI, 48.1–84.9) for occurrence of DPC in all 71 patients. This is the first report to demonstrate the molecular differentiation of STC and DPC. Overall, the integral molecular profile performed excellent discrimination and denoted an exponential function to predict the probability of DPC.

Abstract
BACKGROUND Adjuvant abemaciclib combined with endocrine therapy (ET) previously demonstrated clinically meaningful improvement in invasive disease-free survival (IDFS) and distant relapse-free survival (DRFS) in hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer at the second interim analysis, however follow-up was limited. Here, we present results of the prespecified primary outcome analysis and an additional follow-up analysis. PATIENTS AND METHODS This global, phase III, open-label trial randomized (1 : 1) 5637 patients to adjuvant ET for ≥5 years ± abemaciclib for 2 years. Cohort 1 enrolled patients with ≥4 positive axillary lymph nodes (ALNs), or 1-3 positive ALNs and either grade 3 disease or tumor ≥5 cm. Cohort 2 enrolled patients with 1-3 positive ALNs and centrally determined high Ki-67 index (≥20%). The primary endpoint was IDFS in the intent-to-treat population (cohorts 1 and 2). Secondary endpoints were IDFS in patients with high Ki-67, DRFS, overall survival, and safety. RESULTS At the primary outcome analysis, with 19 months median follow-up time, abemaciclib + ET resulted in a 29% reduction in the risk of developing an IDFS event [hazard ratio (HR) = 0.71, 95% confidence interval (CI) 0.58-0.87; nominal P = 0.0009]. At the additional follow-up analysis, with 27 months median follow-up and 90% of patients off treatment, IDFS (HR = 0.70, 95% CI 0.59-0.82; nominal P < 0.0001) and DRFS (HR = 0.69, 95% CI 0.57-0.83; nominal P < 0.0001) benefit was maintained. The absolute improvements in 3-year IDFS and DRFS rates were 5.4% and 4.2%, respectively. Whereas Ki-67 index was prognostic, abemaciclib benefit was consistent regardless of Ki-67 index. Safety data were consistent with the known abemaciclib risk profile. CONCLUSION Abemaciclib + ET significantly improved IDFS in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer, with an acceptable safety profile. Ki-67 index was prognostic, but abemaciclib benefit was observed regardless of Ki-67 index. Overall, the robust treatment benefit of abemaciclib extended beyond the 2-year treatment period.

Abstract
Breast cancer is the most common female malignancy in Taiwan, while conventional clinical and pathological factors fail to provide full explanation for prognostic heterogeneity. The aim of the study was to evaluate the feasibility of targeted sequencing combined with concurrent genes signature to identify somatic mutations with clinical significance. The extended concurrent genes signature was based on the coherent patterns between genomic and transcriptional alterations. Targeted sequencing of 61 Taiwanese breast cancers revealed 1036 variants, including 76 pathogenic and 545 likely pathogenic variants based on the ACMG classification. The most frequently mutated genes were NOTCH, BRCA1, AR, ERBB2, FANCA, ATM, and BRCA2 and the most common pathogenic deletions were FGFR1, ATM, and WT1, while BRCA1 (rs1799965), FGFR2 (missense), and BRCA1 (rs1799949) were recurrent pathogenic SNPs. In addition, 38 breast cancers were predicted into 12 high-risk and 26 low-risk cases based on the extended concurrent genes signature, while the pathogenic PIK3CA variant (rs121913279) was significantly mutated between groups. Two deleterious SH3GLB2 mutations were further revealed by multivariate Cox’s regression (hazard ratios: 29.4 and 16.1). In addition, we identified several significantly mutated or pathogenic variants associated with differentially expressed signature genes. The feasibility of targeted sequencing in combination with concurrent genes risk stratification was ascertained. Future study to validate clinical applicability and evaluate potential actionability for Taiwanese breast cancers should be initiated.

Abstract
RATIONALE Most gastrointestinal melanomas are metastatic from an oculocutaneous primary lesion; however, primary gastrointestinal melanomas have been found in all levels of the gastrointestinal tract. We present the case of Primary malignant melanoma of the esophagus and discuss the diagnostic methods, differentiation from metastatic lesions and treatment options. PATIENT CONCERNS A 78-year-old male patient presented with fresh blood vomiting and tarry stools for 1 day. DIAGNOSES Esophagogastroduodenoscopy of this patient revealed a tumor ∼4 cm in size at the cardia side of the esophagogastric junction with dark-red and gray pigmentation. Immunohistochemical stains of the biopsy specimens were positive for S-100 and HMB-45, which are specific markers of melanoma. INTERVENTIONS Laparotomy with proximal gastrectomy was performed by the surgeon. Histological examination of the surgical specimen revealed the tumor arose from the distal esophagus with invasion of the proximal stomach. Primary malignant melanoma of the esophagus was diagnosed after a full skin and ophthalmic examination and positron emission tomography, which revealed no lesions elsewhere in the body. OUTCOMES No tumor recurrence was noted at the 1-year follow-up. LESSONS Primary malignant melanoma of the esophagus is an extremely rare but highly aggressive tumor. The special pattern of pigmentation should be recognized while performing endoscopy. Early detection and radical resection of the tumor are critical to ensure favorable outcomes.

Abstract
Objective: To evaluate the clinical effects of 5-fluorouracil in different mass concentrations combined with triamcinolone in the treatment of keloids. Methods: From March 2018 to March 2019, 29 patients with 31 keloids receipted in the Department of Plastic Surgery of Fujian Medical University Union Hospital, 11 patients with 20 keloids receipted in the Department of Dermatology of Pingtan Comprehensive Experimental Area Hospital, and 9 patients with 9 keloids receipted in the Fuzhou Heisey-Dea Aesthetic Clinic were included in this prospectively randomized control study, with 27 males and 22 females, aged (30±9) years. According to the random number table, the keloids were divided into low mass concentration group (19 keloids, 17 patients), medium mass concentration group (21 keloids, 19 patients), and high mass concentration group (20 keloids, 17 patients). Then 5-fluorouracil at mass concentrations of 0.5, 5.0, and 12.5 mg/mL combined with triamcinolone acetonide were injected respectively, once every 4 weeks, for a total of 3 times. Before the first treatment and in 3 months after the last treatment, the appearance of keloids was evaluated by Vancouver Scar Scale (VSS) and pain and pruritus of keloids were evaluated by Visual Analogue Scale (VAS). Then the score differences before and after the treatment were calculated. In 6 months after the last treatment, the patients' efficacy satisfaction was evaluated by efficacy satisfaction rating scale. Adverse reactions during the treatment were recorded. In the follow-up of one year after the last treatment, the recurrence rates of keloids were counted. Data were statistically analyzed with chi-square test, one-way analysis of variance, paired sample t test, least significant difference t test, Wilcoxon rank sum test, Kruskal-Wallis rank sum test, or Fisher's exact probability test. Results: Before the first treatment, the appearance VSS scores of appearance of keloids in the three groups were similar (F=0.039, P>0.05). In 3 months after the last treatment, the appearance VSS scores of keloids in low mass concentration group were significantly higher than those in medium mass concentration group and high mass concentration group (t=2.267, 4.086, P<0.05 or P<0.01). In 3 months after the last treatment, the appearance VSS scores of keloids in low mass concentration group, medium mass concentration group, and high mass concentration group were significantly decreased compared with those before the first treatment (t=18.222, 44.272, 22.523, P<0.01). The differences of appearance VSS scores of keloids in low mass concentration group before and after treatment were significantly lower than those in medium mass concentration group and high mass concentration group (t=-4.096, -6.357, P<0.01), and the differences of appearance VSS scores of keloids in medium mass concentration group before and after treatment were significantly lower than those in high mass concentration group (t=-2.368, P<0.05). Before the first treatment, the pain and pruritus VAS scores of keloids in the three groups were similar (χ2=0.149, P>0.05). In 3 months after the last treatment, the pain and pruritus VAS scores of keloids in low mass concentration group were significantly higher than those in medium mass concentration group and high mass concentration group (Z=2.191, 4.386, P<0.05 or P<0.01), and the pain and pruritus VAS scores of keloids in medium mass concentration group were significantly higher than those in high mass concentration group (Z=2.276, P<0.05). In 3 months after the last treatment, the pain and pruritus VAS scores of keloids in medium mass concentration group and high mass concentration group were significantly decreased compared with those before the first treatment (Z=-3.904, -3.844, P<0.01). The differences of pain and pruritus VAS scores of keloids in low mass concentration group before and after treatment were significantly lower than those in medium mass concentration group and high mass concentration group (Z=-4.265, -6.104, P<0.01). In 6 months after the last treatment, the efficacy satisfaction scores of the corresponding patients of keloids were (88±8) points in high mass concentration group, which were significantly higher than (76±8) points in medium mass concentration group and (60±8) points in low mass concentration group (t=-3.820, -6.675, P<0.01), and the efficacy satisfaction scores of the corresponding patients of keloids in medium mass concentration group were significantly higher than those in high mass concentration group (t=-2.984, P<0.05). There was only statistically significant difference in pain within the 3 groups (P<0.01). In the follow-up of one year after the last treatment, the recurrence rate of keloids in high mass concentration group was significantly lower than that in low mass concentration group (χ2=8.313, P<0.01), and the recurrence rate of keloids in medium mass concentration group was similar to the recurrence rates in low mass concentration group and high mass concentration group (P>0.05). Conclusions: After treating keloids with high mass concentration of 5-fluorouracil combined with triamcinolone acetonide, the symptoms were significantly improved, the efficacy satisfaction of patients was increased, with no obvious adverse reactions but long lasting efficacy. Their overall effects are better than treatment using medium and low mass concentrations of 5-fluorouracil, which is worthy of clinical promotion.

Abstract
The purpose of this three-dimensional cone beam computed tomography (CBCT) study was to identify the difference between monocortical fixation (MCF) and bicortical fixation (BCF) in mandibular canal penetration after bilateral sagittal split osteotomy (BSSO) to correct mandibular prognathism, where interosseous fixation was done by BCF or MCF. CBCT was performed 1 week postoperatively and Dolphin 3D software was used to assess direct penetration of the mandibular canal by either type of screw. The primary outcome variable was the presence or absence of mandibular canal penetration and was categorized as a binary coded variable. The BCF and MCF groups were compared by χ2 test, and the odds ratio for canal penetration was estimated. Multiple logistic regression was performed to identify factors related to canal penetration. A total of 118 patients were included. The MCF group had only 6% canal penetrations (3/50 patients) and the BCF group had 58.8% canal penetrations (40/68 patients). The regression model showed that BCF was the only factor causing mandibular canal penetration, with an adjusted odds ratio of 52.5. Awareness of the increased risk of canal penetration with BCF and potential nerve injury might influence case selection.

Abstract
Orthognathic surgery using a surgery-first approach (SFA) has been shown to result in better quality of life (QoL) throughout the treatment duration; however, the effects of gender, age and type of dentofacial deformity on SFA-related QoL remain unknown. In total, 228 consecutive patients underwent SFA for correction of dentofacial deformities (skeletal class III, bimaxillary protrusion and facial asymmetry). We assessed their QoL before surgery and at 1, 6 and 12 months after surgery using the Orthognathic Quality of Life Questionnaire (OQLQ). The results indicated a significant decrease in the total OQLQ, facial aesthetics and social aspect domain scores 1, 6 and 12 months after surgery. Among all domains, the greatest improvement was noted in the facial aesthetics domain. The oral function scores declined significantly immediately after surgery, but improved significantly 6 and 12 months after surgery; however, the awareness scores remained relatively stable. At each time point, women and the bimaxillary protrusion group exhibited a significantly higher total and specific domain scores. Patients aged 18-22 years exhibited lower total and four specific domain scores than older patients. Thus, QoL improves in all aspects, except awareness domain, by 12 months after SFA, but gender, age, and type of dentofacial deformity affect this improvement.

Abstract
Microcalcification is one of the most common radiological and pathological features of breast ductal carcinoma in situ (DCIS), and to a lesser extent, invasive ductal carcinoma. We evaluated messenger RNA (mRNA) transcriptional profiles associated with ectopic mammary mineralization. A total of 109 breast cancers were assayed with oligonucleotide microarrays. The associations of mRNA abundance with microcalcifications and relevant clinical features were evaluated. Microcalcifications were present in 86 (79%) patients by pathological examination, and 81 (94%) were with coexistent DCIS, while only 13 (57%) of 23 patients without microcalcification, the invasive diseases were accompanied with DCIS (χ2-test, P < 0.001). There were 69 genes with differential mRNA abundance between breast cancers with and without microcalcifications, and 11 were associated with high-grade (comedo) type DCIS. Enriched Gene Ontology categories included glycosaminoglycan and aminoglycan metabolic processes and protein ubiquitination, indicating an active secretory process. The intersection (18 genes) of microcalcificaion-associated and DCIS-associated genes provided the best predictive accuracy of 82% with Bayesian compound covariate predictor. Ten genes were further selected for prognostic index score construction, and five-year relapse free survival was 91% for low-risk and 83% for high-risk group (log-rank test, P = 0.10). Our study suggested that microcalcification is not only the earliest detectable radiological sign for mammography screening but the phenomenon itself may reflect the underling events during mammary carcinogenesis. Future studies to evaluate the prognostic significance of microcalcifications are warranted.

Abstract
BACKGROUND Glue mesh fixation is thought to cause less pain compared to tack mesh fixation during laparoscopic total extraperitoneal inguinal hernia repair (TEP). However, the clinical benefits of glue mesh fixation are still controversial. This study aimed to evaluate the acute pain, chronic pain, and recurrence rate between these two fixation methods. METHODS After reviewing all patients in our prospective hernia repair database from February 2008 to December 2017, we identified 583 patients who underwent TEP with tack mesh fixation and 70 patients with glue fixation by a single surgeon. Acute post-operative pain and activity level were evaluated using a Visual Analog Score (VAS) and the modified Medical Outcome Study (MOS) score. The primary endpoint was chronic pain 6 months after TEP. The secondary endpoints were acute pain, activity level, complications, and recurrence. RESULTS After adjustment for potential confounding factors, the glue mesh fixation had significant lower VAS at 2 h post operation during rest and coughing and on the first day after surgery during coughing (p = 0.005, p < 0.001, and p = 0.011). The modified MOS on the first day was higher in the glue group (p < 0.001). There were no reduced risk of chronic pain or increased risk of recurrence for the glue group compared to the tack group [Odds ratio (OR) = 0.237, p = 0.169; OR = 2.498, p = 0.299]. In the sub-group analysis for recurrent hernia repair, glue fixation is associated with better modified MOS (p = 0.031) on first day and lower VAS on the operative day and first day at rest (p = 0.003 and p = 0.024) after surgery. CONCLUSIONS Glue fixation method was superior to tack fixation method in acute post-operative pain and early post-operative activity level after laparoscopic TEP repair. However, both fixation methods had similar incidence of chronic pain-, recurrence-, and procedure-related complications after laparoscopic TEP repair.

Abstract
Concordance of PAM50 molecular subtyping between oligonucleotide microarray and nanoString nCounter assay for Taiwanese breast cancer
Introduction
Breast cancer is molecularly heterogeneous and at least five molecular subtypes have been defined according to intrinsic genes transcription. Currently microarrays, RT-PCR, and next generation RNA sequencing have been adopted for subtyping in addition to the original nanoString nCounter assay. This study aimed to evaluate the consistency in subtyping Taiwanese breast cancers.
Methods
A total of 109 Taiwanese breast cancers (24 with adjacent normal breast) were assayed with Affymetrix Human Genome U133 plus 2.0 arrays and 96 were assayed with the customized 145-gene nanoString Codeset BCeCSig, of which the academic PAM50 was investigated. Of note, 64 patients were assayed for both platforms. Subtyping with the nearest centroid (single sample prediction) was called for each patient; Spearman's rank correlation coefficients were used, and samples were unclassified if correlation coefficients to all 5 centroids were less than 0.1.
Results
Table 1 showed the distributions of molecular subtypes with clinical IHC results. For 24 matched normal breast tissues, 21 were classified as normal breast-like. For 64 breast cancers (one unclassified) tested for both platforms, 41 (65%) were classified with identical subtype, resulting in a fair Kappa statistic of 0.55. Taking nCounter as gold standard, classification accuracy was 50% (3/6), 72% (13/18), 53% (10/19), 87% (13/15), and 40% (2/5) for basal-like, HER2-enriched, luminal-A, luminal-B, and normal breast-like subtype using Affymetrix microarray. ER-/HER2- phenotype and basal-like subtype experienced worse relapse free survival at 8-year follow-up (55.6% and 63.6% censored).

Conclusions:
Using public domain microarrays as a handy shortcut for breast cancer molecular subtyping is luring in scientific communities. Our experiments showed that fundamental discrepancy existed between distinct approaches, and more cation should be taken without too much extrapolation. On the other hand, adjacent normal breast tissue did display normal breast-like character, and this subtype should be viewed as a continuum of surrounding stroma.

Abstract
Abstract
Purpose:
The aim of the study is to perform targeted sequencing to enhance the prognostic power of breast cancer concurrent genes. Somatic mutations with clinical significance will be identified.
Materials and Methods:
Our previous study had identified the concurrent genes signature from the coherent patterns between genomic and transcriptional profiles among Taiwanese breast cancers, and those predicted into the high-risk group were furthered assayed by targeted sequencing. Target-enrichment sequencing was performed with Illumina SolexaTM technology with read length of 150 bp and was analyzed with Agilent SureCallTM software.
Results:
In total, 109 breast cancer samples were collected during surgery and analyzed with AffymetrixTM U133 plus 2.0 microarrays. Breast cancer risk prediction was performed with the published concurrent genes signature. Targeted sequencing of 61 high-risk breast cancers revealed 1061 variants, including 76 pathogenic and 545 likely pathogenic variants based on ACMG classification. The most impacted genes were NOTCH, BRCA1, AR, ERBB2, FANCA, ATM, and BRCA2, harboring 57, 36, 30, 27, 27, 26, and 26 variants. Table 1 showed that the most frequent pathogenic deletions were FGFR1 , ATM, and WT1 (47, 47, and 37 patients) while BRCA1 (rs1799965, non-sense mutation), FGFR2 (missense mutation), and BRCA1 (rs1799949, non-sense mutation) were the most frequent pathogenic SNPs (44, 35, and 11 breast cancers, respectively). The distributions of deletions and pathogenic SNPs were similar across ER+, HER2+, and triple-negative breast cancers.
Conclusion:
This two-stage predictive model, concurrent genes signature risk stratification followed by targeted sequencing of actionable genes, is believed to provide clinical applicability and substantial benefits for Taiwanese breast cancer patients.

Abstract
BACKGROUND The increasing incidence of colorectal cancer in Taiwan has generated a need for a disease-specific quality-of-life measuring instrument. We aimed to validate the Taiwan Chinese version of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-CR29. METHODS A total of 108 patients were interviewed. Convergent and discriminant validity, Cronbach's alpha coefficient, test-retest reliability, and known-groups comparisons were used to examine the reliability and validity. RESULTS We found good internal consistency reliability for multi-item scales of the QLQ-C30 and QLQ-CR29, except for the cognitive function and pain scale of the QLQ-C30. Patients in the active treatment group reported compromised functional scale scores (global health status/quality of life, QLQ-C30) and worse symptoms (blood and mucus in stool, QLQ-CR29) than those in the follow-up group. Similar results were found in comparisons based on Eastern Cooperative Oncology Group (ECOG) Performance Status and Bristol Stool Scale: higher physical function/sexual interest, less fatigue/urine frequency symptoms for patients with the lowest ECOG Performance Status (Grade 0), and borderline worse stool frequency scores from Types 5 and 6 patients on the Bristol Stool Scale. CONCLUSION The study validated the Taiwan Chinese version of the EORTC QLQ-C30 and QLQ-CR29. The clinical applicability warrants further studies with greater number of participants.

Abstract
BACKGROUND With the development of prosthetic mesh and tension free techniques, the recurrence rate following inguinal hernia repair has been reduced, and hernia outcomes research should focus on post-operative quality of life and potential complications. STUDY DESIGN A novel hernia quality of life assessment instrument, HERQL, was developed. The HERQL questionnaire comprises a 4-item summative pain score measuring pain and discomfort resulting from various strenuous activities. Symptomatic and functional domains, as well as post-operative satisfaction are evaluated as well. RESULTS A total of 386 HERQL surveys were completed by 183 patients with inguinal hernias. Internal consistency reliability of the summative pain score was satisfactory, with a Cronbach's alpha of 0.85. Criterion validity was examined by concomitant assessment of the pain/discomfort and health impact subscales of the EQ-5D questionnaire, with substantial to moderate correlations. Pre-operative patients reported more severe hernia protrusion, more pain during mild to heavy exercise, and worse activity restriction and health impairment than the follow-up patients, indicating clinical validity. The conceptual structure of the HERQL demostrated the causal relationship between the formative symptomatic subscales and the reflective functional status indicators. Repeated measurement of the summative pain scores revealed an estimated time effect of -1.63, which was the rate of change in the summative pain score across the pre-operative, immediately post-operative, and follow-up 3-month periods suggesting the clinical responsiveness of the HERQL. CONCLUSIONS This study will facilitate inguinal hernia outcomes research and enhance the quality of care for this common disease by providing a validated HERQL instrument with enhanced sensitivity.

Abstract
AIM For early-stage breast cancer, four cycles of docetaxel and cyclophosphamide (TC) was proven superior to doxorubicin plus cyclophosphamide in the US Oncology 9375 trial. Given primary prophylactic antibiotics, 5% febrile neutropenia was recorded in a population comprising 75.5% Caucasians. Smaller trials and retrospective studies reviewing TC use in Asian patients did not produce similar incidence rates. This study aims to discover the variable hematological toxicities with TC use in Caucasian and Asian patients. METHODS Breast cancer data was retrospectively reviewed for patients receiving adjuvant docetaxel 60-75 mg/m2 plus cyclophosphamide 600 mg/m2 from six countries (China, Hong Kong, Japan, Taiwan, Italy, and United States). Similar number of patients with relatively balanced baseline characteristics were chosen for analysis of hematological and nonhematological toxicities and survival data. RESULTS From March 2004 to July 2013, data of 227 patients (127 Asians and 100 Caucasian) patients were analyzed for treatment-related toxicities. During the four cycles of TC, Asians had a significantly higher rate of grade ≥2 neutropenia than Caucasians (45.7% vs 6.0%; P <0.001) and significantly more grade ≥3 neutropenia events were documented (respectively 30.7% vs 4.0%, P <0.001). The prophylactic use of G-CSF was similar; 26.0% in Asians and 28.0% in Caucasian (P = 0.764). There were no differences in nonhematological toxicities. No significant difference in disease-free survival was observed between Asians and Caucasians (log-rank P = 0.910). CONCLUSIONS Ethnic differences in toxicity profile exist between Asian and Caucasian patients given adjuvant TC. Over 30% Asians but less than 5% Caucasians experienced grade ≥3 neutropenia.

Abstract
INTRODUCTION An elevated serum urate level is recognised as a cause of gouty arthritis and uric acid stone. The level of serum uric acid that accelerates kidney stone formation, however, has not yet been clarified. This study aimed to find out if a high serum urate level is associated with nephrolithiasis. METHODS Patients were recruited from the rheumatology clinic of Taipei City Hospital (Renai and Zhongxing branches) in Taiwan from March 2015 to February 2016. A total of 120 Chinese male patients with newly diagnosed gout and serum urate concentration of >7 mg/dL and no history of kidney stones were divided into two groups according to their serum urate level: <10 mg/dL (group 1, n=80) and ≥10 mg/dL (group 2, n=40). The mean body mass index, blood urea nitrogen level, creatinine level, urinary pH, and kidney ultrasonography were compared between the two groups. RESULTS There were no significant differences in blood urea nitrogen or creatinine level between the two groups. The urine pH in both groups was similar and not statistically significant. Kidney stone formation was detected via ultrasonography in 6.3% (5/80) and 82.5% (33/40) of patients in groups 1 and 2, respectively (P<0.05). CONCLUSION A serum urate level of ≥10 mg/dL may precipitate nephrolithiasis. Further studies are warranted to substantiate the relationship between serum urate level and kidney stone formation.

Abstract
Isoflurane-induced neurocognitive impairment in the developing rodent brain is well documented, and regular physical exercise has been demonstrated to be a viable intervention for some types of neurocognitive impairment. This study was designed to investigate the potential protective effect of swimming exercise on both neurocognitive impairment caused by repeated neonatal exposure to isoflurane and the underlying molecular mechanism. Mice received 0.75% isoflurane exposures for 4h on postnatal days 7, 8, and 9. From the third month after anesthesia, the mice were subjected to regular swimming exercise for 4weeks, followed by a contextual fear condition (CFC) trial. We found that repeated neonatal exposure to isoflurane reduced freezing behavior during CFC testing and deregulated hippocampal histone H4K12 acetylation. Conversely, mice subjected to regular swimming exercise showed enhanced hippocampal H3K9, H4K5, and H4K12 acetylation levels, increased numbers of c-Fos-positive cells 1h after CFC training, and less isoflurane-induced memory impairment. We also observed increases in histone acetylation and of cAMP-response element-binding protein (CREB)-binding protein (CBP) during the swimming exercise program. The results suggest that neonatal isoflurane exposure-induced memory impairment was associated with dysregulation of H4K12 acetylation, which may lead to less hippocampal activation following learning tasks. Swimming exercise was associated with enhanced hippocampal histone acetylation and CBP expression. Exercise most likely ameliorated isoflurane-induced memory impairment by enhancing hippocampal histone acetylation and activating more neuron cells during memory formation.

Abstract
OBJECTIVES Malnutrition is a serious concern in hospitals and is known to be associated with increased complications for patients, increased hospital costs and length of stay. Trained volunteers that assist 'at risk' and malnourished patients at lunch meals have been shown to effectively increase nutritional intake in a suburban hospital in Sydney. The pilot study reported here aimed to evaluate and share learnings from a similar, newly implemented program, comparing energy and macronutrient intakes on days with no volunteer assistance, to days with volunteers. DESIGN Dietary intakes were determined by visual estimation of meal trays before and after meals, for two days without volunteers, and two days with volunteer assistance at lunch. Macronutrient and energy intakes were compared and data such as weight, height, diet type and medical history were obtained from medical records. Questionnaires were completed by nurses and volunteers in regards to their views and experiences with the program. SETTING Hospital based. RESULTS Eight patients (83±4.5 years) participated in the study. When volunteers were present at lunch, the average macronutrient and energy intakes increased, though not statistically significantly. The mean increases were 316 kJ (p=0.175) for energy, 3.1 g (p=0.468) for protein, 1.4 g (p=0.418) for fat and 11.6 g (p=0.084) for carbohydrates. Non-significant increases in macronutrients were also noted for the average daily intakes. CONCLUSION Although not statistically significant, energy and macronutrient intakes increased when volunteers were present. The implementation of a volunteer feeding assistance program is one strategy to assist dietary intakes but requires a ready team of volunteers, training, acceptance and significant time to develop.

Abstract
OBJECTIVE This study aimed to evaluate the conceptual structure of the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (EORTC QLQ-C30) by analyzing data collected from patients with major cancers in Taiwan. The conceptual structure underlying QLQ-C30, including higher-order factors, was explored by structural equation modeling (SEM). METHODS The Taiwan Chinese version of the EORTC QLQ-C30 was used as the measuring instrument. Higher-order models, including mental health/physical health, mental function/physical burden, symptom burden/function, single latent health-related quality of life, formative symptom burden/function, and formative health-related quality of life, were tested. RESULTS Study subjects included 283 patients with breast, lung, and nasopharyngeal cancers. The original QLQ-C30 multi-factorial structure demonstrated poor composite reliability of the cognitive function subscale. The formative symptom/burden model was favored by model fit indices, further supporting causal-indicator duality, but was compromised by unexpected associations between symptomatic subscales and latent factors. The formative health-related quality of life was proposed with a single second-order latent factor where symptomatic subscales remained formative. Two additional symptom measures from the formal cognitive function subscale with the formative health-related quality-of-life model were proposed as the alterative conceptual structure for the Taiwan Chinese QLQ-C30. CONCLUSIONS Results of the current study represent the complete SEM approach for the EORTC QLQ-C30. The formative health-related quality-of-life model with elimination of cognitive function enhances the conceptual structure of the Taiwan Chinese version with parsimonious fit and interpretability.

Abstract
Abstract
Our recent work had identified concurrent gene signatures which highlighted the interplay between copy number variation (CNV) and differential gene expression (GE) for Han Chinese breast cancers. The merit of the approach is the discovery of biomarkers not readily identified by conventional GE only data, for which phenotype-correlation or gene variability is the criteria of gene selection.
A total of 31 array CGH and 83 GE arrays (29 samples with data from both platforms) were performed. Potential targets of cancer therapy were revealed by Genomic Identification of Significant Targets in Cancer (GISTIC) from 31 array CGH. We used these concurrent genes as well as genes with significant GISTIC scores to derive signatures associated with clinical ER, HER2 status, and disease-free survival.
The most common gain regions were 1q21.2 and 17q12-q21.1 while the most common lost region was 22q11.23. In subgroup analysis, recurrent gains for ER positive cancers were 8p23.1, and 8p11.23-11.21. For HER2 overexpressing tumors, recurrent gain was 17q12-21.1 and recurrent losses were 8p11.22, 8p12, and 8p23.1. We identified 1,584 concurrent genes from 29 samples assayed for both array CGH and GE microarrays, and enriched concurrent gene sets for ER, HER2 and disease-free survival were identified independently from our 83 GE arrays (GSE48391) and two series with Han Chinese origin (GSE5460 and GSE20685) as well as three studies of Western countries (GSE7390, GSE2034 and GSE3494). Signature genes were consensus genes from leading edge analysis across all studies, and we used supervised partial least square (PLS) regression to derived predictive model of clinical ER, HER2 and disease-free survival with each signature gene further weighted by the coefficient of concurrence as an additive tuning parameter. The predictive accuracy was 92.3% for ER and 84.6% for HER2 in 208 Han Chinese breast cancers and was 87.3% for ER in 735 breast cancers in Western countries. For five studies with disease-free survival data (no survival data for GSE5460), prognostic discrepancy was observed in four studies except GSE3493 between high-risk and low-risk patients predicted with the concurrent signature.
We conclude that parallel analysis of CGH and microarray data, in conjunction with known gene expression patterns, can be used to identify biomarkers with prognostic values in breast cancer.

Abstract
The aim of the study is to evaluate gene component analysis for microarray studies. Three dimensional reduction strategies, Principle Component Regression (PCR), Partial Least Square (PLS) and Reduced Rank Regression (RRR) were applied to publicly available breast cancer microarray dataset and the derived gene components were used for tumor classification by Logistic Regression (LR) and Linear Discriminative Analysis (LDA). The impact of gene selection/filtration was evaluated as well. We demonstrated that gene component classifiers could reduce the high-dimensionality of gene expression data and the collinearity problem inherited in most modern microarray experiments. In our study gene component analysis could discriminate Estrogen Receptor (ER) positive breast cancers from negative cancers and the proposed classifiers were successfully reproduced and projected into independent microarray dataset with high predictive accuracy.

Abstract
The interplay between copy number variation (CNV) and differential gene expression may be able to shed light on molecular process underlying breast cancer and lead to the discovery of cancer-related genes. In the current study, genes concurrently identified in array comparative genomic hybridization (CGH) and gene expression microarrays were used to derive gene signatures for Han Chinese breast cancers. We performed 23 array CGHs and 81 gene expression microarrays in breast cancer samples from Taiwanese women. Genes with coherent patterns of both CNV and differential gene expression were identified from the 21 samples assayed using both platforms. We used these genes to derive signatures associated with clinical ER and HER2 status and disease-free survival. Distributions of signature genes were strongly associated with chromosomal location: chromosome 16 for ER and 17 for HER2. A breast cancer risk predictive model was built based on the first supervised principal component from 16 genes (RCAN3, MCOLN2, DENND2D, RWDD3, ZMYM6, CAPZA1, GPR18, WARS2, TRIM45, SCRN1, CSNK1E, HBXIP, CSDE1, MRPL20, IKZF1, and COL20A1), and distinct survival patterns were observed between the high- and low-risk groups from the combined dataset of 408 microarrays. The risk score was significantly higher in breast cancer patients with recurrence, metastasis, or mortality than in relapse-free individuals (0.241 versus 0, P<0.001). The concurrent gene risk predictive model remained discriminative across distinct clinical ER and HER2 statuses in subgroup analysis. Prognostic comparisons with published gene expression signatures showed a better discerning ability of concurrent genes, many of which were rarely identifiable if expression data were pre-selected by phenotype correlations or variability of individual genes. We conclude that parallel analysis of CGH and microarray data, in conjunction with known gene expression patterns, can be used to identify biomarkers with prognostic values in breast cancer.

Abstract
CONTEXT The compound 4,7-dimethoxy-5-(2-propen-1-yl)-1,3-benzodioxole (apiole) has been isolated from several different plant species, including Petroselinum sativum. Our recent study found that apiole is a chemical derivative of 4,7-dimethoxy-5-methyl-l,3-benzodioxole (SY-1), which has been isolated from dried Antrodia camphorata (AC ) fruiting bodies, a traditional Chinese medicine with antitumor properties. AIMS Our previous in vitro study demonstrated that apiole inhibits the growth of human colon (COLO 205) cancer cells through the arrest of the cell cycle in G0/G1 phase. The in vivo antitumor effects of apiole were evaluated in this study. SETTING AND DESIGN Apiole was administered to mice at 1-30 mg/kg body weight through intraperitoneal (I.P.) injection three times per week (defined as a dosage of 1×-30×). MATERIALS AND METHODS The in vivo antitumor effects of apiole were evaluated in mice with xenografts of COLO 205 cells. STATISTICAL ANALYSIS All of the data are reported as the means ± S.E. Comparisons were performed with a one-way analysis of variance (ANOVA) followed by a Fisher's least significant difference test. Significance was defined as P < 0.05. RESULTS Apiole (> 1×) markedly decreased the growth of COLO 205 human colon cancer cell tumor xenografts in an athymic nude mouse model system through the up-regulation of cell cycle regulators, such as p53, p21/Cip1, and p27/Kip1. The apiole-induced increase in G0/G1 phase cell cycle regulators was also associated with a significant decrease in the expression of cyclins D1 and D3. Surprisingly, statistically significantly higher tumor volumes were observed in mice that received 5× apiole compared with 30× apiole-treated mice (P < 0.05). No gross signs of toxicity were observed (e.g., body weight changes, general appearance, or individual organ effects) in any group. CONCLUSIONS Our results show, for the first time, the promising antitumor effects of apiole against colon tumors in an in vivo xenograft model.

Abstract
Ethanol consumption induces hepatocellular carcinoma (HCC) cell metastasis by changing the extracellular matrix (ECM). Lysyl oxidase (LOX) catalyzes the cross-linkage of collagen or elastin in the ECM. LOX protein and mRNA overexpression (>21-fold compared with controls, n = 6) was detected in cirrhotic HCC patients with a history of alcoholism. LOX protein expression was induced in HCC cells after long-term treatment with ethanol (10 mM) for 20-40 passages (denoted E20-E40 cells). Pterostilbene (PSB, 1 μM) displayed significant potency to reduce LOX-mediated activity in E40 cells when combined with curcumin and its analogues. The ability of E40 cells to form colonies in soft agar was reduced by both genetic depletion of LOX and by chemical inhibitors of LOX expression. This study suggests that targeting LOX expression with food components such as PSB and curcumin may be a novel strategy to overcome ethanol-induced HCC cell metastasis in liver cancer patients.

Abstract
PURPOSE Laparoscopic incisional and ventral hernia repair (LIVHR) has been advocated for short hospital stay, rapid ambulation, and low recurrence rates and has gained increasing popularity. We report here the outcomes of long-term follow-up of LIVHR. SUBJECTS AND METHODS The series comprised 100 LIVHR procedures performed between June 2000 and February 2004. LIVHR was performed with the standard three-trocar configuration. Underlay expanded polytetrafluoroethylene mesh was placed in a tension-free manner and bridged the fascia defect with an adequate overlap of at least 4 cm. Enrolled patients were prospectively followed up at return visits. RESULTS Two conversions due to densely scarred abdomen were inevitable. There were four true recurrences (4%) and three eventrations (loss of prosthetic elasticity) (3%). There was no difference in recurrence rate and eventrations among ventral, incisional, and recurrent incisional hernias. Patients with recurrent incisional hernias reported more seroma formations, and seroma formation was independently associated with adhesiolysis (adjusted odds ratio=4.57). CONCLUSIONS Long-term follow-up of LIVHR was satisfactory both in complications and in recurrences. The efficacy of LIVHR was ascertained and reproducible for Taiwanese patients. The concerns with chronic pain necessitate preoperative counseling with patients indicated or planned for LIVHR.

Abstract
For many years, the understanding of gastrointestinal stromal tumors (GISTs), which are the most common mesenchymal tumors of the gastrointestinal tract, has been very limited. However, it is now possible to provide a more precise definition through the use of pathology classification and molecular techniques. Coupled with the advancement of clinical practice, especially the development of targeted therapy, there is now a much better insight into its treatment. At present, organizations such as the National Comprehensive Cancer Network in the USA and the European Society for Medical Oncology in Europe have established a consensus and drawn up guidelines for the diagnosis, treatment, and follow-up of GISTs.With experts coming from various districts in Taiwan and combining the most recent clinical data and experiences, the Taiwan Surgical Society of Gastroenterology drafted the first national GIST treatment guidelines after a consensus meeting in 2007. Following subsequent advances in GIST diagnosis and treatment, further revisions and modifications have been made to the original guidelines. We present here the updated consensus and recommendations of the Taiwan Surgical Society of Gastroenterology for the diagnosis and treatment of GIST. We hope these guidelines can help enhance the quality of diagnosis, treatment, and care of patients with GIST in Taiwan.

Abstract
Breast cancer is the most common malignancy among women and has an age-specific incidence profile. Over the last decade, many studies have demonstrated the anticancer activity of α-tocopherol, the main and most active form of natural vitamin E. α-Tocopherol-associated protein (TAP) was found to be one of the major α-tocopherol binding proteins in human serum and in liver, brain, and prostate tissues. In this study, we found that reduced TAP expression was significantly correlated with Her2/neu receptor expression, breast cancer stage and nodal stage in paired normal and cancerous breast tissue samples from 93 patients using real-time PCR analysis. A cell viability assay showed that α-tocopheryl succinate (α-TOS), a synthetic derivative of α-tocopherol, enhanced the cells' sensitivity to doxorubicin and resulted in a reduction in cell viability in breast cancers. Taken together, these data suggest that the use of vitamin E or its analogue as a dietary supplement may be beneficial for the treatment of cancer.

Abstract
Background Breast cancer is a heterogeneous disease in terms of transcriptional aberrations; moreover, microarray gene expression profiles had defined 5 molecular subtypes based on certain intrinsic genes. This study aimed to evaluate the prediction consistency of breast cancer molecular subtypes from 3 distinct intrinsic gene sets (Sørlie 500, Hu 306 and PAM50) as well as clinical presentations of each molecualr subtype in Han Chinese population. Methods In all, 169 breast cancer samples (44 from Taiwan and 125 from China) of Han Chinese population were gathered, and the gene expression features corresponding to 3 distinct intrinsic gene sets (Sørlie 500, Hu 306 and PAM50) were retrieved for molecular subtype prediction. Results For Sørlie 500 and Hu 306 intrinsic gene set, mean-centring of genes and distance-weighted discrimination (DWD) remarkably reduced the number of unclassified cases. Regarding pairwise agreement, the highest predictive consistency was found between Hu 306 and PAM50. In all, 150 and 126 samples were assigned into identical subtypes by both Hu 306 and PAM50 genes, under mean-centring and DWD. Luminal B tended to show a higher nuclear grade and have more HER2 over-expression status than luminal A did. No basal-like breast tumours were ER positive, and most HER2-enriched breast tumours showed HER2 over-expression, whereas, only two-thirds of ER negativity/HER2 over-expression tumros were predicted as HER2-enriched molecular subtype. For 44 Taiwanese breast cancers with survival data, a better prognosis of luminal A than luminal B subtype in ER-postive breast cancers and a better prognosis of basal-like than HER2-enriched subtype in ER-negative breast cancers was observed. Conclusions We suggest that the intrinsic signature Hu 306 or PAM50 be used for breast cancers in the Han Chinese population during molecular subtyping. For the prognostic value and decision making based on intrinsic subtypes, further prospective study with longer survival data is needed.

Abstract
In this study, 4,7-dimethoxy-5-methyl-1,3-benzodioxole (SY-1) was isolated from three different sources of dried Antrodia camphorata (AC) fruiting bodies. AC is a medicinal mushroom that grows on the inner heartwood wall of Cinnamomum kanehirai Hay (Lauraceae), which is an endemic species that is used in Chinese medicine for its antitumor properties. We demonstrated that SY-1 [given as a 1-30 mg/kg body weight intraperitoneal (ip) injection three times per week] profoundly decreased the growth of COLO-205 human colon cancer cell tumor xenografts in an athymic nude mouse model. We further demonstrated that significant AC extract-mediated antitumor effects were observed at the highest concentration (5 g/kg body weight/day). No gross toxicity signs were observed (i.e., body weight changes, general appearance, or individual organ effects). Frozen COLO-205 xenograft tumors were pulverized in liquid N(2), and the expression of cell cycle regulatory proteins was detected by immunoblotting. We found that the p53-mediated p27/Kip1 protein was significantly induced in the low-dose (1 mg/kg body weight) SY-1-treated tumors, whereas the p21/Cip1 protein levels did not change. The G0/G1 phase cell cycle regulators induced by SY-1 were also associated with a significant decrease in cyclins D1, D3, and A. These results provide further evidence that SY-1 may have significance for cancer chemotherapy.

Abstract
This analysis was undertaken to compare the clinicopathological features of infants with choledochal cysts to those of older children with these entities and to evaluate the surgical outcomes for both subject groups. The medical records of all children admitted to the Cathay General Hospital with choledochal cysts over a 20-year period were retrospectively reviewed. Twenty-five subjects were included and divided into the infant (<1 year at presentation; 8 subjects) and classical pediatric (1-18 years at presentation; 17 subjects) groups. Anatomical subtypes were: IA (16), IC (6), and IVA (3). The median biliary amylase value was markedly elevated for the pediatric group but not for the infant group. Most (82.4%) patients in the pediatric group, but none in the infant group, presented with abdominal pain. Jaundice and clay-colored stool were present in all patients in the infant group but only 35% of those in the pediatric group. All patients underwent choledochocystectomy and Roux-en-Y hepaticojejunostomy with good outcomes. Neonates/infants with choledochal cysts present differently from older children with these entities. Amylase measurements may serve to distinguish biliary atresia with cystic dilatation from choledochal cyst in neonates/infants. Prognosis following radical cyst excision and reconstruction with Roux-en-Y hepaticojejunostomy is excellent.

Abstract
Metaplastic carcinoma of the breast (MCB) is a rare subtype of breast cancer. Anecdotal reports are available regarding its response to systemic chemotherapy. We reviewed the records of patients diagnosed with MCB at National Taiwan University Hospital between 1988 and 2009. A total of 46 MCB cases were identified from 8,695 breast tumor patients who underwent biopsy or resection. About 11 of 25 patients with initial bulky disease (T3-4) received neoadjuvant chemotherapy before surgery, and 2 (18.2%) exhibited a partial response. About 12 of 18 patients who developed distant metastasis received palliative systemic chemotherapy. Of them, only 1 (8.3%), 1 (10%), and none (0%) responded to first-, second-, or third- and beyond line chemotherapy, respectively. None of the patients who received anthracyline- (n = 13), vinorelbine- (n = 7), or cyclophosphamide-based (n = 18) chemotherapy responded, whereas 3 (17.6%) of 17 patients who received taxane-based chemotherapy exhibited a partial response. Tumor response to systemic chemotherapy remains generally poor for MCB patients. Taxanes may have modest activity, but need to be validated in further studies.

Abstract
PURPOSE Clinically, we have observed the phenomenon of postoperatively accelerated orthodontic tooth movement in patients who had orthognathic surgery. This phenomenon lasts for a period of 3 to 4 months. However, the underlying mechanisms of this phenomenon have not been well studied yet. The purpose of this prospective clinical pilot study was to study the postoperative changes in bone physiology and metabolism and the corresponding responses in the dentoalveolus, such as the changes in tooth mobility. MATERIALS AND METHODS Twenty-two consecutive adult patients who had 2-jaw orthognathic surgery were included in this study. The levels of serum alkaline phosphatase and C-terminal telopeptide of type I collagen (ICTP), as well as the tooth mobility of the maxillary and mandibular incisors based on the Periotest method (Siemens AG, Bensheim, Germany), were examined preoperatively and 1 week, 1 month, 2 months, 3 months, and 4 months postoperatively. The data were analyzed statistically. RESULTS Both tooth mobility of the maxillary and mandibular incisors and ICTP significantly increased from 1 week to 3 months postoperatively and then decreased to their preoperative levels in the fourth month postoperatively. The changes in tooth mobility were significantly in correspondence with the changes in ICTP. The alkaline phosphatase level significantly increased from the first to fourth month postoperatively, but it was not significantly correlated to the changes in tooth mobility. CONCLUSION The orthognathic surgery triggers a 3- to 4-month period of higher osteoclastic activities and metabolic changes in the dentoalveolus postoperatively, which possibly accelerates postoperative orthodontic tooth movement.

Abstract
SCOPE The aim of this research was to explore whether the tea-polyphenol (-)-epigallocatechin-3-gallate (EGCG) could be used as a potential agent for blocking smoking (nicotine, Nic)- or hormone (estradiol, E2)-induced breast cancer cell proliferation through inhibition of a common signaling pathway. METHODS AND RESULTS To explore whether Nic (>0.1 μM, 24 h) and E2 (>1 nM, 24 h) significantly increased α9-nicotinic acetylcholine (α9-nicotinic acetylcholine receptor (nAChR)) mRNA and protein expression levels, real-time PCR and immunoblotting analysis experiments were performed in human breast cancer (MCF-7) cells. Luciferase promoter activity experiment was performed to test the α9-nAChR promoter activity affected by Nic, E2 or EGCG. The results indicate that treatment with EGCG (1 μM) profoundly decreases Nic- and E2-induced MCF-7 proliferation by down regulating α9-nAChR expression. The α9-nAChR promoter activity is significantly induced by 24-h treatment with Nic (10 μM) or E2 (10 nM) (>1.8 and ∼2.3-fold, respectively) in MCF-7 cells. Pretreatment with EGCG eliminated the Nic- and E2-induced α9-nAChR promoter-dependent luciferase activity. We further demonstrate that combined treatment with EGCG profoundly inhibits [3H]-Nic/ α9-nAChR binding activity in breast cancer cells. CONCLUSIONS We found that the EGCG could be used as an agent for blocking smoking (Nic)- or hormone (E2)-induced breast cancer cell proliferation by inhibiting of α9-nAChR signaling pathway. This study reveals the novel antitumor mechanisms of EGCG, and these results may have significant applications for chemopreventive purposes in human breast cancer.

Abstract
A photonic crystal substrate exhibiting resonant enhancement of multiple fluorophores has been demonstrated. The device, fabricated uniformly from plastic materials over a ∼3×5 in.(2) surface area by nanoreplica molding, utilizes two distinct resonant modes to enhance electric field stimulation of a dye excited by a λ=632.8 nm laser (cyanine-5) and a dye excited by a λ=532 nm laser (cyanine-3). Resonant coupling of the laser excitation to the photonic crystal surface is obtained for each wavelength at a distinct incident angle. Compared to detection of a dye-labeled protein on an ordinary glass surface, the photonic crystal surface exhibited a 32× increase in fluorescent signal intensity for cyanine-5 conjugated streptavidin labeling, while a 25× increase was obtained for cyanine-3 conjugated streptavidin labeling. The photonic crystal is capable of amplifying the output of any fluorescent dye with an excitation wavelength in the 532 nm<λ<633 nm range by selection of an appropriate incident angle. The device is designed for biological assays that utilize multiple fluorescent dyes within a single imaged area, such as gene expression microarrays.

Abstract
BACKGROUND The aim of this study was to evaluate changes in quality-of-life following laparoscopic cholecystectomy (LC) in adults with cholelithiasis. METHODS Patients were evaluated with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI) preoperatively and 12 months after LC. Outcome predictors were analyzed using correlation and regression statistics. RESULTS Ninety-nine patients were enrolled (male/female, 32:67, age 49.8 +/- 13.7 years old). At baseline, patients performed inferiorly to general population in all SF-36 general health dimensions (p < 0.0001). Postoperatively, the "role-physical", "role-emotional", and "bodily pain" dimensions of health significantly improved. There were significant improvements in GIQLI "total", "physical well-being", "mental well-being", "gastrointestinal digestion", and "defecation" subscales scores. Serum direct bilirubin level and drainage tube indwelling were significant predictors for quality-of-life improvement following LC. CONCLUSIONS LC can greatly reduce gastrointestinal symptoms to improve quality-of-life for patients with cholelithiasis. Patients with severe baseline conditions may benefit from greater quality-of-life improvement following LC.
