Cervical cancer ranks as the fourth leading cause of cancer death in women worldwide. In Taiwan, although the universal health insurance system has achieved 99.9% coverage and ensured easy access to medical care, some cervical cancer patients continue to delay initiation of definitive treatment after diagnosis. This study focused on cervical cancer patients who delayed treatment for at least 4 months, and examined the characteristics, related factors, and survival in these patients. ⋯ Those who delayed treatment had 2.31 times the mortality risk of those who underwent timely treatment (P < 0.05). Delayed cervical cancer treatment in Taiwan was associated with age, comorbidity, cancer stage, diagnosing hospital level, and hospital ownership. Delaying treatment for ≥4 months substantially raised mortality risk in cervical cancer patients.

We investigated the risk factors for adenoma occurrence at surveillance colonoscopy, especially focusing on patient characteristics, including metabolic factors. Surveillance colonoscopy intervals depend on baseline adenoma characteristics. However, patients' characteristics may also influence the occurrence of adenomas. ⋯ The cumulative incidence of adenoma occurrence in the high-risk group was higher than that in the low-risk group, whereas the incidence in the high-risk group without MetS was comparable with that in the low-risk group with MetS. Patient characteristics, such as MetS, obesity, older age, and male sex, in addition to adenoma characteristics, were independent risk factors for adenoma occurrence at surveillance colonoscopy. These patient characteristics may be considered in surveillance colonoscopy intervals.

The aim of this study was to determine the features of triple-negative breast cancer (TNBC) using a large national database. TNBC is known to be an aggressive subtype, but national epidemiologic data are sparse. All patients with invasive breast cancer and known molecular subtype diagnosed in 2010 to 2011 were identified from the National Cancer Data Base (NCDB). ⋯ On univariate analysis, TNBC was no more likely than non-TNBC to have node-positive disease (32.0% vs 31.7%, respectively, P = 0.218) but in a multivariable analysis controlling for tumor size and grade, TNBC was associated with significantly less node-positivity (OR = 0.59; 95% confidence interval [CI]: 0.57-0.60). TNBC has distinct features regarding age, gender, geographic, and racial distribution. Compared to non-TNBC, TNBC is larger and higher grade, but less likely to have lymph node metastases.

Observational Study
Awake nasotracheal fiberoptic intubation and self-positioning followed by anesthesia induction in prone patients: A pilot observational study.
Anesthesia followed by placement in the prone position takes time and may result in complications. This study aimed to evaluate the feasibility of awake nasotracheal fiberoptic intubation and self-positioning followed by anesthesia induction in prone-positioned patients under general anesthesia. Sixty-two patients (ASA physical status I-II) scheduled for awake nasotracheal fiberoptic intubation and prone self-positioning before surgery under general anesthesia were selected. ⋯ Compared with values before intubation, SBP, DBP, HR, and RPP were slightly increased after intubation, although the difference was not statistically significant (P > 0.05). One patient had moderate coughing and 1 patient had gagging during prone self-positioning, which were tolerable. These findings indicated that awake nasotracheal fiberoptic intubation and self-positioning followed by induction of anesthesia is safe and feasible alternative to routine prone positioning after induction of general anesthesia.

No risk assessment tool is available for identifying high risk population of breast cancer (BCa) in Hong Kong. A case-control study including 918 BCa cases and 923 controls was used to develop the risk assessment model among Hong Kong Chinese women. Each participant received an in-depth interview to obtain their lifestyle and environmental risk factors. ⋯ The AUCs were 0.640 (95% CI, 0.598-0.681) and 0.655 (95% CI, 0.621-0.653) for pre- and postmenopausal women, respectively. Further subgroup evaluation revealed that the model performance was better for women aged 50 to 70 years or ER-positive. This BCa risk assessment tool in Hong Kong Chinese women based on LASSO selection is promising, which shows a slightly higher discriminative accuracy than those developed in other populations.
