BACKGROUND Nomograms are visual predictive tools that are widely used for estimating cancer prognosis. The purpose of this study was to develop a prognostic tool that will accurately predict overall survival (OS) in individual patients with oral cancer. METHODS Medical records of 609 patients with cancer of the oral cavity were retrospectively analyzed. The stepdown method was used to select ...

BACKGROUND A nomogram could provide individualized prognostic for papillary thyroid carcinoma (PTC). The purpose of our study was to develop and validate a new nomogram. METHODS Consecutive patients with PTC from 2 different institutions were analyzed and divided into the development (n = 849) and validation (n = 275) sets. The former was used for formulating a nomogram in predicting disease-...

OBJECTIVE The potential risk of postoperative morbidity is important for gynecologic cancer patients because it leads to delays in adjunctive therapy and additional costs. We aimed to develop a preoperative nomogram to predict 30-day morbidity after gynecological cancer surgery. METHODS Between 2005 and 2015, 533 consecutive patients with elective gynecological cancer surgery in our center we...

OBJECTIVE To develop a clinical tool that integrates different risk factors and provides individual predictions of the risk of biopsy progression in patients with prostate cancer managed by active surveillance. MATERIALS AND METHODS Our analysis included 205 patients on active surveillance, each of whom had had at least two surveillance biopsies. We used the Cox proportional hazard regression...

INTRODUCTION Before radical prostatectomy (RP), a nomogram [Briganti et al., Eur Urol 2012;61:584-592] permits to measure the probability of specimen-confined (SC) disease (pT2-pT3a, node negative with negative margins) in high-risk prostate cancer (PCa). The aim of our study was to perform an external validation of this nomogram. MATERIALS AND METHODS Between 2007 and 2011, 623 patients with...

BACKGROUND The TNM staging system is far from perfect in predicting the survival of individual cancer patients because only the gross anatomy is considered. The survival rates of the patients who have the same TNM stage disease vary across a wide spectrum. This study aimed to develop a nomogram that incorporates other clinicopathologic factors for predicting the overall survival (OS) of non-met...

BACKGROUND We aimed to develop a new nomogram to predict the probability of level 2 axillary lymph node metastasis (L-2-ALNM) in breast cancer (BC) patients treated with neoadjuvant chemotherapy (NAC). METHODS Data were collected from 709 patients who received neoadjuvant chemotherapy and then underwent axillary lymph node (ALN) dissection between May 2009 and December 2015 at the Liaoning Ca...

The aim of this study was to construct an effective clinical nomogram for predicting the survival of esophageal cancer patients after esophagectomy. We identified esophageal cancer patients (n = 4,281) who underwent esophagectomy between 1988 and 2007 from the Surveillance, Epidemiology, and End Results (SEER) 18 registries database. Clinically significant parameters for survival were used to c...

BACKGROUND Nomogram accuracies for predicting non-sentinel lymph node (SLN) involvement vary between different patient populations. Our aim is to put these nomograms to test on our patient population and determine our individual predictive parameters affecting SLN and non-SLN involvement. PATIENTS AND METHODS Data from 932 patients was analyzed. Nomogram values were calculated for each patien...

A nomogram based on both western and eastern populations to estimate the Disease Specific Survival (DSS) of resectable gastric cancer (RGC) has not been established. In current study, we retrospectively analyzed 4,379 RGC patients who underwent curative resection from the Surveillance, Epidemiology, and End Results (SEER) database. Patients diagnosed between 1998 and 2009 were assigned as train...
