Because of different prognosis of gastric cancer patients with the same T and N stages, the impossibility of N3 staging in patients with fewer than 15 removed lymph nodes, and the presence of stage migration phenomenon, the 6th edition TNM Staging System for gastric cancer was updated to the 7th edition TNM staging system in 2009. Despite some opposing views, the superiority of the 7th edition ...

There is no consensus on predicting prognosis for hepatocellular carcinoma patients undergoing radiotherapy. This study aims to evaluate the validity of different staging systems. Overall, 249 hepatocellular carcinoma patients were evaluated retrospectively. All patients were classified by different staging systems. The cumulative survival rates were calculated using the Kaplan-Meier method, an...

BACKGROUND AND PURPOSE CT and MR imaging are widely used for the staging of head and neck cancer. Currently, there are no data regarding whether the primary tumor, nodes, metastasis (TNM) staging is routinely incorporated into radiology reports. We conducted a national survey to determine whether radiologists routinely address staging, in particular regarding T (primary tumor) and N (nodal). ...

The gradient monotonicity of existing tumor, node, metastases staging systems for colorectal cancer is unsatisfactory. Our proposed T-plus staging system strengthens weighting of the T stage. In this study, applicability of the T-plus staging system was verified with data of a Chinese colorectal cancer center. Records of 2080 nonmetastatic, advanced cancer patients undergoing colorectal cancer ...

Cancer staging provides a basis for planning clinical management, but also allows for meaningful analysis of cancer outcomes and evaluation of cancer care services. Despite this, stage data in cancer registries is often incomplete, inaccurate or simply not collected. This article describes a prototype software system (Cancer Stage Interpretation System, CSIS) which automatically extracts cancer...

BACKGROUND Staging laparoscopy can detect radiographically occult peritoneal metastases and prevent futile laparotomy in patients with gastric adenocarcinoma. We sought to assess the use of staging laparoscopy for gastric adenocarcinoma in a cohort of older patients and to compare outcomes after laparoscopy alone with nontherapeutic laparotomy. STUDY DESIGN Using Surveillance, Epidemiology an...

It is universally recognized that an accurate and precise staging and classification system for gestational trophoblastic neoplasia (GTN) is essential to enable clinicians to assess the prognosis or the risk of patients, to individualize and to optimize their treatment. There have been a variety of staging and classification systems developed by different centres and some are still being used. ...

BACKGROUND Cervical cancer is the third most common gynecological cancer and a widespread malignancy in women, accounting for a large proportion of the cancer burden in developing countries. We compared accuracy of MRI staging with clinical staging and also concordance between the two methods for newly diagnosed patients with cervical cancer, using clinical staging as the reference.
