RESUMO

BACKGROUND: We describe a DNA methylation assay, named MPap test, using cervical scraping as an alternative technique for endometrial cancer detection. METHODS: A multicenter hospital-based, two-stage validation study was conducted to validate the cancer detection performance of the MPap test. The MPap value was determined from the DNA methylation status of two genes (BHLHE22, CDO1) and combined with two other clinical variables (age, BMI). The cutoff threshold of the MPap value was established in stage 1 and validated in stage 2. A total of 592 women with abnormal uterine bleeding were enrolled from five medical centers throughout Taiwan. RESULTS: In stage 1, the sensitivity, specificity, and positive and negative predictive values of the MPap test for detecting endometrial cancer were 92.9%, 71.5%, 39.8%, and 98.0%, respectively. These values were validated in stage 2, being 92.5%, 73.8%, 40.2%, and 98.1%. Moreover, MPap outperformed transvaginal ultrasound in sensitivity and negative predictive values for detecting endometrial cancer. When we applied the algorithm for triage of endometrial cancer detection by MPap in the Taiwan National Health Insurance dataset, we found that it may reduce invasive procedures by 69~73%. CONCLUSIONS: MPap may provide a feasible alternative for endometrial cancer detection and can be considered as a triage test to reduce unnecessary invasive procedures.

RESUMO

BACKGROUND: As obesity is becoming pandemic, morbid obesity (MO), an extreme type of obesity, is an emerging issue worldwide. It is imperative to understand the factors responsible for huge weight gain in certain populations in the modern society. Very few genome-wide association studies (GWAS) have been conducted on MO patients. This study is the first MO-GWAS study in the Han-Chinese population in Asia. METHODS: We conducted a two-stage GWAS with 1110 MO bariatric patients (body mass index [BMI] ≥ 35 kg/m2) from Min-Sheng General Hospital, Taiwan. The first stage involved 575 patients, and 1729 sex- and age-matched controls from the Taiwan Han Chinese Cell and Genome Bank. In the second stage, another 535 patients from the same hospital were genotyped for 52 single nucleotide polymorphisms (SNPs) discovered in the first stage, and 9145 matched controls from Taiwan Biobank were matched for confirmation analysis. RESULTS: The results of the joint analysis for the second stage revealed six top ranking SNPs, including rs8050136 (p-value = 7.80 × 10- 10), rs9939609 (p-value = 1.32 × 10- 9), rs1421085 (p-value = 1.54 × 10- 8), rs9941349 (p-value = 9.05 × 10- 8), rs1121980 (p-value = 7.27 × 10- 7), and rs9937354 (p-value = 6.65 × 10- 7), which were all located in FTO gene. Significant associations were also observed between MO and RBFOX1, RP11-638 L3.1, TMTC1, CBLN4, CSMD3, and ERBB4, respectively, using the Bonferroni correction criteria for 52 SNPs (p < 9.6 × 10- 4). CONCLUSION: The most significantly associated locus of MO in the Han-Chinese population was the well-known FTO gene. These SNPs located in intron 1, may include the leptin receptor modulator. Other significant loci, showing weak associations with MO, also suggested the potential mechanism underlying the disorders with eating behaviors or brain/neural development.

RESUMO

OBJECTIVE: To share our experience of transition from multiport to single-site robotic surgery for benign gynecological conditions as well as to assess the selection criteria of candidates for robotic single-site supracervical hysterectomy (RSSH). MATERIALS AND METHODS: A retrospective review was conducted on patients undergoing robotic supracervical hysterectomy by a single surgeon in a single institute between June 2014 and December 2017. Patients who underwent additional procedures along with supracervical hysterectomy and who had unexpectant corpus malignancy proved pathologically were excluded from comparisons between patients undergoing RSSH and robotic multiport supracervical hysterectomy (RMSH). RESULTS: Between June 2014 and December 2017, we accomplished 26 RSSH and 57 RMSH. There were no conversions, intraoperative complications, and readmissions within 30 days after surgery. In the RSSH group, the mean uterine weight was 264.6 ± 140.9 g with mean docking time of 15.8 ± 5.5 min, mean console time of 61.1 ± 35.6 min and mean operative time of 140.3 ± 34.4 min. In comparison to the RMSH group, the percentage of overweight/obese patients was lower (p = 0.018) and the uterine size was smaller (p < 0.001) with adenomyosis diagnosed more frequently (p = 0.002) in the RSSH group. While the operative time in the RSSH group was significantly shorter (p = 0.002), the RSSH group took longer time in docking (p < 0.001) and comparable time in console (p = 0.254). In view of chronological change, docking time and console time in the RMSH group remained steady, whereas steep decreases were observed in the RSSH group. The intraoperative blood loss and hemoglobin drop were comparable. The length of hospital stay was significantly shorter in the RSSH group (p = 0.005). CONCLUSION: Transition from multiport to single-site surgery can be smooth for a surgical team experienced in the conventional multiport robotic system. RSSH is safe and feasible in properly selected patients.

RESUMO

OBJECTIVE: Obesity is one of the most important public health issues worldwide. Moreover, an extreme phenotype, morbid obesity (MO) has insidiously become a global problem. Therefore, we aimed to document the prevalence trend and to unveil the epidemiological characteristics of MO in Taiwan. METHODS: Nationally representative samples aged 19 years and above from three consecutive waves of Nutrition and Health survey in Taiwan: 1993-1996, 2005-2008, and 2013-2014 (n = 3,071; 1,673; and 1,440; respectively) were analyzed for prevalence trend. And 39 MO (BMI ≥35 kg/m2) cases from the two recent surveys compared with 156 age, gender, and survey-matched normal weight controls (BMI: 18.5-24 kg/m2) for epidemiological characteristics study. The reduced rank regression analysis was used to find dietary pattern associated with MO. RESULTS: The prevalence of overweight and obesity together (BMI ≥24 kg/m2) was stabilized in the recent two surveys, but that of MO (0.4%, 0.6%, to 1.4%) and obesity (BMI ≥27 kg/m2) (11.8%, 17.9%, to 22.0%) increased sharply. MO cases tended to have lower levels of education, personal income, and physical activity. Furthermore, their dietary pattern featured with a higher consumption frequency of red meat, processed animal products, and sweets/sweetened beverage, but lower frequencies of fresh fruits, nuts, breakfast cereal, and dairy products. CONCLUSION: This study documents a polarization phenomenon with smaller proportion of overweight people at the center and higher proportions of normal weight and obesity subjects at two extremes. MO was associated with low socioeconomic status and poor dietary pattern. The obesogenic dietary pattern became more prevalent in later time.

RESUMO

BACKGROUND: Transarterial chemoembolization (TACE) can reduce tumor progression and help achieve good locoregional effect in hepatocellular carcinoma (HCC) patients with intrahepatic multiple recurrence (IHMR) after liver resection (LR). The effect of TACE on HCC patients with IHMR after liver transplantation (LT) remains unclear. The purpose of this study was to investigate the effect of TACE on IHMR after LR or LT. MATERIAL AND METHODS: This hospital-based retrospective study included 968 and 180 HCC patients who had undergone LR or LT, respectively, in the past decade. Parameters included clinical characteristics, alpha-fetoprotein level, Child classification, tumor stage at first treatment, tumor size at recurrence, and recurrence and survival status. The groups were compared using the t test or chi-square test, and univariate and multivariate analyses were performed. Survival and recurrence were analyzed by the Kaplan-Meier method. Differences were significant at P<0.05. RESULTS: During follow-up, 112 patients had IHMR: 101 after LR and 11 after LT. Age, sex distribution, and HCV infection rate differed significantly between the LR and LR groups. All patients in the LT group who had recurrent HCC died within 3 years. The risk factors for death from tumor recurrence included a larger tumor size at recurrence, poor Child classification at recurrence, hyperbilirubinemia, hypoalbuminemia, and no TACE treatment. In Cox regression analysis, only vessel invasion, Child class C, and no TACE treatment were independent risk factors for death from tumor recurrence. CONCLUSIONS: TACE is beneficial for treating IHMR in patients after LR or LT.
