Establishment and Verification of Prognostic Nomograms for Patients with Gastrointestinal Stromal Tumors: A SEER-Based Study.

With gastrointestinal tract as the origin, gastrointestinal stromal tumor (GIST) is recognized as the very widespread mesenchymal tumor. A precise prognostic model of survival is required to guide the treatment options of patients with GIST. This study was designed to map the overall survival (OS) and cancer-specific survival (CSS) of GIST patients.

[Research on Application of Fourier Transform Infrared Spectrometry in the Diagnosis of Lymph Node Metastasis in Gastric Cancer].

To explore the feasibility of quick intraoperative in situ and noninvasive diagnosis of lymph node metastasis in gastric cancer by Fourier transform infrared (FTIR) spectrometry. FTIR spectra of surgically removed fresh lymph nodes were measured by FTIR via probe of attenuated total reflection (ATR). For each spectrum, 13 bands were indentified and assigned between 3 000 and 1 000 cm(-1).

[Intra-abdomen extragastrointestinal stromal tumors: a clinicopathologic study on 30 cases].

Objective: To investigate the clinicopathological characteristics and prognostic factors in patients with intra-abdomen extragastrointestinal stromal tumors (EGISTs).

Methods: The data of 47 patients of mesenchymal neoplasms that arose from the abdominal cavity and retroperitoneum, collected from July 1987 to June 2003 in our hospital with complete clinical and pathological data, were investigated retrospectively. EGISTs were diagnosed by reviewing the tumor slides stained with hematoxylin and eosin (H&E).

[Analysis of prognostic and clinicopathologic factors in gastrointestinal stromal tumors of the stomach].

Objective: To identify the clinical pathological characteristics and prognostic factors in patients with gastrointestinal stromal tumors of the stomach.

Methods: The data of 98 patients of gastric stromal tumors, leiomyomas, leiomyosarcomas, leiomyoblastomas, schwannomas and neurofibromas, collected from Mar. 1983 to Dec.

[Analysis of prognostic factors in gastrointestinal stromal tumors of the small intestine].

Objective: To explore the prognostic factors in patients with gastrointestinal stromal tumors of the small intestine.

Methods: Tumor slides stained with hematoxylin and eosin from these patients were reviewed. Two histomorphologically representative areas were identified and arrayed on a tissue microarray.

Surgical salvage therapy of anal cancer.

Aim: To evaluate the results of salvage resection in the management of persistent or locally recurrent anal canal cancer.

Methods: Details of all patients with anal canal cancer treated from 1978 to 1994 at Cancer Hospital of Chinese Academy of Medical Sciences (CAMS) were reviewed retrospectively. Sixteen patients who presented with persistent or locally recurrent anal canal cancer received salvage surgery.
