[CLINICAL PATHOLOGICAL FEATURES AND SURVIVAL RATE FACTORS IN COMPLICATED PRIMARY GASTROINTESTINAL CANCERS]
Summary
This study on gastrointestinal cancers found that obstruction was the most common complication. Early diagnosis and surgical treatment are crucial for improving the five-year survival rate in these patients.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Clinical Pathology
Background:
- Complicated primary gastrointestinal cancers pose significant challenges in diagnosis and treatment.
- Understanding clinical-pathological features and prognostic factors is essential for improving patient outcomes.
Purpose of the Study:
- To determine the clinical-pathological features of 115 patients with complicated gastrointestinal cancers.
- To identify prognostic factors influencing the five-year survival rate, particularly in cases of obstruction.
Main Methods:
- Retrospective evaluation of 115 patients who underwent surgical resection for complicated gastrointestinal cancers between 1966 and 1996.
- Analysis of clinical data, pathological findings, and survival rates.
Main Results:
- Obstruction was the most frequent complication (72%), followed by perforation (17%) and hemorrhage (11%).
- Gastric adenocarcinoma was associated with obstruction and hemorrhage; small bowel neoplasms, especially lymphomas, were linked to perforation.
- The overall five-year survival rate was 13%, higher in obstructed cases. Tumor size and macroscopic type were significant for gastric outlet obstruction, while tumor size and clinical stage were key for colon cancer obstruction.
Conclusions:
- Early diagnosis and timely surgical intervention are critical for improving survival in patients with complicated gastrointestinal cancers.
- Identifying prognostic factors like tumor size, macroscopic type, and clinical stage can guide treatment decisions.
