BACKGROUND Asthma exacerbation may require a visit to the emergency room as well as hospitalization and can occasionally be fatal. However, there is limited information about the prognostic factors for asthma exacerbation requiring hospitalization, and no methods are available to predict an inpatient's prognosis. We investigated the clinical features and factors affecting in-hospital mortality ...

PURPOSE The degree of benefit from palliative chemotherapy differs widely among patients with metastatic esophageal squamous cell carcinoma (MESCC). The purpose of this study was to develop and validate a prognostic nomogram to predict survival and aid physicians and patients in the decision-making process regarding treatment options. MATERIALS AND METHODS Clinicopathologic variables and trea...

BACKGROUND Men who undergo radical prostatectomy (RP) are at long-term risk of biochemical recurrence (BCR). In this report, the authors have described a model capable of predicting BCR up to at least 15 years after RP that can adjust predictions according to the disease-free interval. METHODS Cox regression was used to model the probability of BCR (a prostate-specific antigen level>0.1 ng/mL...

PURPOSE The purpose of this study was to determine the efficacy of the Vienna nomogram prostate biopsy model in the detection of prostate cancer in our local population. We also assessed the incidence of complications from using such a template. MATERIALS AND METHODS From January 2006 to June 2007, 120 men with either elevated prostate-specific antigen (PSA) scores (>4 ng/mL) and/or abnormal ...

OBJECTIVE The purpose of this study is to estimate the risk of postoperative lymphocele development after lymphadenectomy in gynecologic cancer patients through establishing a nomogram. METHODS We retrospectively reviewed 371 consecutive gynecologic cancer patients undergoing lymphadenectomy between 2009 and 2014. Association of the development of postoperative lymphocele with clinical charac...

Increased lymph node count (LNC) has been associated with prolonged survival in colorectal cancer (CRC), but the underlying mechanisms are still poorly understood. The study aims to identify new predictors and develop a preoperative nomogram for predicting the probability of adequate LNC (≥ 12). 501 eligible patients were retrospectively selected to identify clinical-pathological factors associ...

BACKGROUND Although the American Board of Internal Medicine (ABIM) certification is valued as a reflection of physicians' experience, education, and expertise, limited methods exist to predict performance in the examination. PURPOSE The objective of this study was to develop and validate a predictive tool based on variables common to all residency programs, regarding the probability of an int...

AIM To identify risk factors for lymph node metastasis using a nomogram for gastric cancer patients to predict lymph node metastasis. RESULTS The Chi-square test and the logistic regression showed that the Boarrmann type, preoperative CA199 level, T stage and N stage by CT scan were independent risk factors. The concordance index (C-index) was 0.786 in the internal validation of the Nomogram ...

OBJECTIVE To develop a preoperative nomogram to predict pathologic outcome in patients submitted to radical prostatectomy for clinical localized prostate cancer. MATERIALS AND METHODS Nine hundred and sixty patients with clinical stage T1 and T2 prostate cancer were evaluated following radical prostatectomy, and 898 were included in the study. Following a multivariate analysis, nomograms were...
