Insights
Colorectal cancer in patients 30 years or younger is uncommon but presents with advanced disease. Early recognition of symptoms like abdominal pain and rectal bleeding is crucial for timely diagnosis.
Area of Science:
- Oncology
- Gastroenterology
- Surgical Oncology
Background:
- An increasing incidence of colorectal carcinoma in young patients (≤30 years) has been observed.
- This study details the experience with this demographic at University Hospital, Kuala Lumpur.
Purpose of the Study:
- To analyze the clinical characteristics, treatment, and outcomes of colorectal cancer in patients aged 30 years or younger.
- To raise awareness among clinicians regarding this rare presentation of colorectal cancer.
Main Methods:
- A retrospective review of all primary colorectal carcinoma cases admitted between 1990 and 1994.
- Inclusion criteria: patients aged 30 years or younger at diagnosis.
- Data collected: demographics, tumor site, symptoms, histology, disease extent, and survival.
Main Results:
- Twenty-one patients (mean age 20-29 years) were included; 67% were Chinese, and 57% were female.
- Tumors were frequently located in the rectosigmoid (29%) or cecum (24%).
- The 5-year survival rate was 25%, with most patients presenting with extensive disease and mucinous histology.
Conclusions:
- Colorectal cancer in young patients often presents with advanced disease, commonly beyond the transverse colon.
- Key presenting symptoms include abdominal pain, hematochezia, or positive fecal occult blood tests.
- These symptoms warrant consideration of colorectal carcinoma in the differential diagnosis for young patients.
Background/Aims:
Recently an increasing number of young colorectal carcinoma patients attending the University Hospital, Kuala Lumpur were noted. This report represents our experience with patients suffering from colorectal cancer aged 30 years or younger.
Materials And Methods:
All cases of primary carcinoma of the colon and rectum admitted to the University Hospital during 1990 to 1994 were respectively reviewed. Inclusion criteria was that the patient had been 30 years or younger. Data collected included age, gender, race, site of tumour, presenting symptomatology, duration of symptoms, histology, extension of tumour and nodal involvement predisposing factors, treatment and follow-up.
Results:
21 patients were included, 5 patients (24%) were 30 years old at diagnosis, 12 (57%) patients were aged 20-29 years and 4 patients (19%) were less than 20 years old. Thirteen of the 21 patients were female, and 8 (38%) were male, 6 of the 21 patients (29%) were Malaysian, while 1 was Indian (4%). The remainder were Chinese, 14 patients (67%). Six patients (29%) had their primary tumour located in the rectosigmoid, 4 (19%) in the left colon, 1 (4%) in the splenic flexure, 2 in the transverse colon (9%), 1 in the hepatic flexure (4%) and 5 in the caecum 24(%). One patient had a tumour too diffuse to detect a primary site at the time of operation. One patient with a family history of polyps had his entire colon removed at age 14. He had 3 separate foci of tumour. The 5-year survival rate was 25%.
Discussion:
Most patients with extensive disease and mucinous histology. Lesions are commonly seen beyond the transverse colon (57%). Presentation included most commonly abdominal pain, haematochezia or haemoccult positive stools.
Conclusion:
The symptoms above should alert surgeons to colorectal carcinoma as a differential diagnosis.
