BACKGROUND Prediction of postoperative survival for hilar cholangiocarcinoma (HCCA) remains difficult although there have been a variety of clinical classification and staging systems. This study was designed to validate and compare some of the major HCCA staging systems in use today. In addition, we sought to build up a new staging system modified from Jarnagin-Blumgart (J-B) classification fo...

BACKGROUND The 7th UICC N stage may be unsuitable for remnant gastric cancer (RGC) because the original disease and previous operation usually cause abnormal lymphatic drainage. However, the prognostic significance of the current TNM staging system in RGC has not been studied. METHODS Prospective data from 153 RGC patients who underwent curative gastrectomy from Jan 1995 to Aug 2009 were revi...

I N CHRONIC lymphocytic leukemia (CLL), a centam number of prognostic factors have been isolated. Some of them were grouped by Rai et al.’ in a clinical staging system that has been widely acepted and venified.2 However, some attempts to improve this classification have been carried out.79 Recently, an International Workshop on CLL’#{176}has recommended a modified system for CLL staging, which ...

BACKGROUND The purpose of this study was to assess the prognostic value of the 3 staging systems found in the literature for sinonasal mucosal melanomas tumors: the Ballantyne staging system modified by Prasad (Ballantyne/Prasad staging system), the American Joint Committee on Cancer (AJCC) TNM classification for mucosal melanomas (mmTNM), and the 2009 AJCC TNM classification for carcinomas of ...

Early studies had shown that metastatic lymph node (LN) was one of the most critical prognostic factors in gastric carcinoma (Hohenberger and Gretschel, 2003; Yokota et al, 2004; Dicken et al., 2005). Since the International Union Against Cancer tumor node metastasis (UICC TNM) classification for LN staging standard was modified in 1997, LN metastatic sites were replaced by the number of metast...

To compare the log odds of positive lymph nodes (LODDS) with the number of positive lymph nodes (pN), lymph node ratio (LNR), removed lymph node (RLN) count, and negative lymph node (NLN) count in determining the prognosis of patients with esophageal squamous cell carcinoma (ESCC) after esophagectomy. The records of patients with ESCC who received esophagectomy were retrospectively reviewed. Th...

Introduction Endometrial carcinoma is the fourth most common female cancer and the most common malignancy of the female reproductive tract. Incidence of the disease is increasing due to longevity and rising levels of obesity [1]. Endometrial cancer is staged with the FIGO system which was recently been modified and has incorporated MRI into the staging system [2]. The new FIGO staging system ha...
