Introduction & Objective: Gastric cancer is one of the most common cancers in Iran, and in some regions, the prevalence of this cancer is the highest among all diagnosed cancers, also it has the highest mortality rate. Concerning to different tumoral mutations that have role in prognosis and type of treatments in different cancers, this study was done to determine the association between p53 ...
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...
Preoperative imaging for staging of rectal cancer has become an important aspect of current approach to rectal cancer management, because it helps to select suitable patients for neoadjuvant chemoradiotherapy and determine the appropriate surgical technique. Imaging modalities such as endoscopic ultrasonography, computed tomography, and magnetic resonance imaging (MRI) play an important role in...
RATIONALE Assessment of mediastinal lymph nodes is recommended in patients with non-small cell lung cancer without distant metastases. Linear transesophageal endoscopic ultrasound with real-time guided fine-needle aspiration (EUS-FNA) is a promising, nonsurgical tool for mediastinal staging. OBJECTIVES We conducted a randomized controlled trial comparing surgical staging with EUS-FNA. METHO...
OBJECTIVE To determine outcomes of patients with early stage epithelial ovarian cancer (EOC) who underwent incomplete surgical staging with those who had complete surgical staging. MATERIAL AND METHOD Retrospective chart reviews were performed on early EOC (FIGO Stage I-II) patients who had registered in the Department of Obstetrics and Gynecology, King Chulalongkorn Memorial Hospital between...
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 ...
High-resolution pelvic magnetic resonance imaging (MRI) is the primary method for staging rectal cancer. MRI is highly accurate in the primary staging of rectal cancer; however, it has not proven to be effective in re-staging, especially in complete response evaluation after neoadjuvant therapy. Neoadjuvant chemoradiotherapy produces many changes in rectal tumors and on adjacent area, as a resu...
IMPORTANCE The current American Joint Committee on Cancer (AJCC) staging system for oral cancer demonstrates wide prognostic variability within each primary tumor stage and provides suboptimal staging and prognostic information for some patients. OBJECTIVE To determine if a modified staging system for oral cancer that integrates depth of invasion (DOI) into the T categories improves prognosti...
Staging of lung cancer serves 2 purposes; it attempts to classify patients into groups where particular treatments are appropriate and defines those groups based on expected prognosis. The eighth edition of the International Association for the Study of Lung Cancer staging system deals with the issues raised by screening with fine cut computed tomography. Each phase of staging is a legitimate d...
