Syndromes of polyposis coli and cancer

Nonfamilial intestinal polyposis and brain tumor in a 5-year-old girl

A 5-year-old girl with glioblastoma multiforme and simultaneous adenocarcinoma in one of multiple colonic polyps is the youngest reported case of Turcot's syndrome. A literature survey and a classification based on family pedigree and pattern of inheritance are proposed.

Surgical alternatives in the treatment of polyposis coli

The history of familial polyposis coli and its various surgical treatment alternatives are presented. Each form of treatment has advantages and disadvantages. The menu of alternatives allows the surgeon the freedom to choose the best option for each patient.

The significance of synchronous carcinoma and polyps in the colon and rectum

The relationship of colorectal carcinoma with polyps was studied retrospectively in 1202 patients. The incidence of synchronous carcinoma (SC) and metachronous carcinoma (MC), prognosis, and recurrence patterns were studied. Synchronous polyps (SP) were found in 36% of the patients. SC was found in 4.4% of the patients, and MC developed in 3.5% of patients. The incidence of SC and of MC increased with SP, and varied according to number, size, and histologic features of the polyps. The adjusted 5-year survival rate was improved in patients with SP compared with those without SP, both overall (79% versus 64%, respectively) and by Dukes' Stage B (87% versus 73%, respectively) and Dukes' Stage C (56% versus 39%, respectively). The pattern of relapse was the same for the SP and non-SP groups. Subtotal colectomy is recommended for colorectal carcinoma and SP in good-risk patients.

Ileal adenomas in familial polyposis coli. Differences before and after colectomy

We treated two patients with familial polyposis coli (FPC) who were found to have multiple adenomas in the ileostomy stoma, five and seven years after colectomy, respectively. These adenomas were dense and 3 to 10 mm in diameter. The adjacent ileal mucosa showed a colonic metaplasia. Ileal adenomas detected using intraoperative intestinal endoscopy at the time of colectomy were less than 2 mm in diameter and sparse in density. These findings suggest that ileal adenomas occurring after colectomy for FPC tend to increase in size and number and to resemble colonic adenomas.
