Colorectal cancers in Saudi Arabia

Area of Science:

• Oncology
• Gastroenterology
• Pathology

Background:

• Colorectal cancer (CRC) is a significant global health concern.
• Understanding the histopathological profile of CRC is crucial for diagnosis and treatment.
• Limited data exists on CRC histopathology within the Kingdom of Saudi Arabia.

Purpose of the Study:

• To characterize the histopathological features of colorectal cancers at King AbdulAziz University Hospital, Jeddah.
• To compare these findings with existing literature from other regions in Saudi Arabia.
• To assess the age distribution and presentation patterns of colorectal cancer in the study population.

Main Methods:

• Retrospective analysis of 39 colorectal cancer cases diagnosed between January 1996 and December 2000.
• Histopathological examination of tumor differentiation, Duke's staging, and grade.
• Comparison of histopathological characteristics with patient age.

Main Results:

• Colorectal adenocarcinoma was the most common type (81%), with a mean age of 56.
• Other identified types included signet cell carcinoma, mucinous adenocarcinoma, and rare variants.
• A notable percentage of patients (21%) presented in their third decade, indicating potential early-onset disease.

Conclusions:

• Colorectal carcinoma presents frequently in the Saudi population, with some cases showing earlier onset than observed in the United States.
• The findings highlight the need for enhanced cancer education and screening programs for early diagnosis of CRC.
• Further comparative studies across different regions of Saudi Arabia are warranted.
