HYPOTHESIS A nomogram based on regression analysis of intraoperative parathyroid hormone level decay discriminates single gland disease from multiglandular (MG) disease more accurately than the currently used 50% rule. DESIGN Retrospective case series. SETTING Academic health center. PATIENTS Two hundred thirty-five patients (222 patients with single gland disease and 13 patients with MG ...

Objective Radiofrequency ablation has been used widely for the local ablation of hepatocellular carcinoma, particularly in its early stages. The study aim was to identify significant prognostic factors and develop a predictive nomogram for patients with hepatocellular carcinoma who have undergone radiofrequency ablation. We also developed the formula to predict the probability of 3- and 5-year ...

PURPOSE To develop a nomogram predictive of current bone scan positivity in patients receiving androgen-deprivation therapy (ADT) for advanced prostate cancer; to augment clinical judgment and highlight patients in need of additional imaging investigations. MATERIALS AND METHODS A retrospective chart review of bone scan records (conventional (99m)Tc-scintigraphy) of 1,293 patients who receive...

This study sought to develop an effective and reliable nomogram for predictions of recurrence for postoperative adjuvant transarterial chemoembolization (PA-TACE) in patients with hepatitis B virus-related (HBV) hepatocellular carcinoma (HCC).The nomogram was established based on data obtained from a retrospective study on 235 consecutive patients with HBV HCC who received PA-TACE as an initial...

BACKGROUND Although QT prolongation is associated with increased risk of torsade de pointes (TdP), the precise relationship is not well defined. AIM To evaluate the performance of a QT nomogram in assessing the risk of TdP from QT-RR combinations. DESIGN Systematic review. METHODS We systematically searched MEDLINE/EMBASE for cases of drug-induced TdP. Controls were patients taking non-ca...

This study aimed to develop a nomogram to predict fluorescence in situ hybridization (FISH) assay results for HER2-borderline breast cancer as determined via immunohistochemistry (IHC) among patients in China. We reviewed a database of breast cancer patients diagnosed between January 2007 and April 2013 at our institutions. We used logistic regression to develop a nomogram and we used receiver ...

Objective: The aim of this study was to establish a simple nomogram as a reference measure to predict lymph node metastases (LNM) in stage T1 colorectal cancer patients, ultimately aiding in the development of treatment strategies. Materials and methods: This study retrospectively analyzed 19,238 patients with pathological stage T1NanyM0 colorectal cancer who underwent surgical resection from 1...

PURPOSE To identify prognostic factors related to outcome in 255 patients with synovial sarcoma and to construct a preoperative nomogram to predict the risk of disease-specific death. DESIGN Between July 1982 and June 2006, 301 patients underwent treatment at our institution for primary synovial sarcoma of all anatomic sites and 255 patients with localized disease at presentation were resecte...

BACKGROUND A proportion of UC patients with restorative proctocolectomy and IPAA develop pouch failure. Accurate risk assessment is critical for making proper evaluation and treatment. Information on factors that may reliably predict pouch failure for the patients requiring referral to a specialized care unit is minimal. AIM We sought to develop and internally validate a nomogram for the pred...

OBJECTIVE Regarding vulvar cancer, a nomogram has been suggested for the prediction of relapse-free survival (RFS). While the nomogram has been developed and validated in a Western study, there was no validation in Korean population. Thus, we have undertaken the study to assess the applicability of nomogram for predicting RFS in Korean patients with vulvar cancer. METHODS A total of 204 cases...
