Insights
Solitary juvenile polyps (SJP) in children do not increase the risk of developing new polyps or colorectal cancer later in life. This study found no predisposition to future polyps or malignancy in children or their relatives after SJP removal.
Area of Science:
- Pediatric Gastroenterology
- Colorectal Surgery
- Oncology
Background:
- Solitary Juvenile Polyps (SJP) are common in children, but their long-term implications are unclear.
- It remains unknown if SJP predisposes to new polyps or colorectal neoplasia.
- This study investigates the risk of future polyps and cancer in children with SJP and their families.
Purpose of the Study:
- To determine if SJP in children increases the risk of developing new juvenile polyps.
- To assess the association between SJP and the risk of colorectal neoplasia (adenomatous polyps or colon cancer).
- To evaluate the long-term outcomes for children treated for SJP and their first-degree relatives.
Main Methods:
- Follow-up study of 24 children who underwent polypectomy for histologically confirmed SJP between 1983-1995.
- Data collected included age, gender, polyp location, personal history, and family history.
- Investigation included medical records review and information gathering from 146 first-degree relatives.
Main Results:
- The mean follow-up period was 4.1 years.
- One child experienced rectal bleeding attributed to hemorrhoids, with no other large bowel abnormalities found.
- No first-degree relatives were diagnosed with adenomatous polyps or colorectal cancer.
Conclusions:
- Solitary Juvenile Polyps (SJP) do not appear to predispose children to developing new juvenile polyps.
- SJP is not associated with an increased risk of colorectal malignancy in children or their families.
Background/Aims:
Solitary Juvenile Polyps (SJP) are quite common in preschool children, although they may occur at any age. It is not known whether the existence of a single juvenile polyp in a child predisposes to future development of new SJP or is related to colorectal neoplasia. The present study was designed to follow up young patients who had undergone polypectomy for SJP and their first degree relatives to elucidate the development of adenomatous polyps or colon cancer.
Materials And Methods:
From 31 children polypectomized for histologically proven SJP between 1983-1995, we were able to contact and gather information on 24. From our records and the information collected we studied age, gender, site of the polyp in the bowel, personal history, and family history.
Results:
Mean time of follow up was 4.1 years (range 0.4-10, SD +/- 3.1) Mean age was 4.6 years (Range 3.5-9, SD +/- 1.2). There were 14 boys and 10 girls (ratio 1.4/1). Eighteen polyps were located at the rectosigmoid area, 5 in the lower descending colon, and one in the splenic flecture. From the 24 children, only one girl developed rectal bleeding at the age of 15 years, 8 years after polypectomy. However, subsequent evidence from the large bowel did not reveal any abnormality and the symptom was attributed to hemorrhoidal bleeding. Thorough investigation of the history of 146 first degree relatives (dead or alive) siblings, parents, and grandparents revealed that none of them were diagnosed with adenomatous polyps or colorectal cancer.
Conclusion:
SJP does not predispose to future development of new juvenile polyps and is not associated with a high risk of colorectal malignancy.
