Clinical features in familial polyposis coli. Results of the Danish Polyposis Register.

Three hundred nineteen affected members of 94 Danish families with familial polyposis coli had been registered in the Danish Polyposis Register by the end of 1982. Of the 247 histologically verified cases, 168 were propositi and 79 were call-up patients. The frequency of colorectal cancer at the time of diagnosis of polyposis was 69 percent in propositi vs. 3 percent in call-up patients. The cumulative survival rate after ten years was 97 percent in call-up patients, as compared to 42 percent in propositi. The prognosis of polyposis patients has improved significantly since the establishment of the Danish Polyposis Register in 1971.

The incidence and prevalence of familial polyposis coli in Denmark.

Based on the Danish Polyposis Register, the frequency of familial polyposis coli was estimated at the end of 1982. The mean annual incidence rate of polyposis coli has remained rather constant at approximately 1 X 10(-6) X yr-1 since the forties. The life-time risk of developing polyposis coli is about 1 X 10(-4). The point prevalence rate was 26 X 10(-6) at the end of 1982. The number of cases found in sibs and children of probands made it probable that a nation-wide prophylactic examination of first degree relatives resulted in a complete identification of affected family members. The completeness of the Danish Polyposis Register in the period 1976-82 was estimated to be 90% and the validity of the diagnosis is considered to be 100%.

Mandibular osteomas in colorectal adenomas.

Orthopantomography of the mandible was carried out on 50 patients with colorectal adenoma(s) without carcinoma or any known familial disposition. Four patients (8%) had osteomas, and we advance the hypothesis that individuals with both osteomas and adenomas represent a separate type of adenoma patient. Further studies are needed to evaluate the prognostic value of the association of adenomas and mandibular osteomas.

Mandibular osteomas in unaffected sibs and children of patients with familial polyposis coli.

Orthopantomography of the mandible (OTM) showed osteomas in 3 of 34 non-affected sibs and children of the probands in 14 families with polyposis coli. The observed to expected ratio with osteomas was 0.35, which is not significantly lower than 1.0 and in accordance with the frequency in the normal population. Although the result does not enable a definite evaluation of the diagnostic value of OTM, the finding suggests that this method may be used as a supplement to regular proctosigmoidoscopic screening of first-degree relatives of polyposis patients.

IgG heavy-chain (Gm) allotypes in familial polyposis coli.

Serum samples from 40 Danish patients with familial polyposis coli and 105 normal blood donors were typed for eight Gm and one Km markers. The distribution of all Gm phenotypes as a group was significantly different in the patient population as compared to the controls. Examination of individual Gm phenotypes showed an increased frequency of Gm3;5,13 in the patients.

Gastroduodenal polyps in familial polyposis coli.

A total of 26 patients with familial polyposis coli without extracolonic manifestations were examined by gastroduodenoscopy. Histologically verified polyps were found in 18 patients (69 percent, 95 percent confidence limits 48-86). Gastric adenoma was diagnosed in one patient, fundic gland polyposis in six patients, and duodenal adenomas in 12 patients. It is concluded that the incidence of gastroduodenal polyps is independent of the clinical presence of other extracolonic manifestations. It is advisable that polyposis patients should be followed with gastroduodenoscopy and biopsy of polyps.

Chromosomal studies in familial polyposis coli.

A study of five patients with familial polyposis coli did not demonstrate any structural abnormalities of prometaphase chromosomes from methotrexate synchronized peripheral blood lymphocytes. No chromosomal heritable fragile sites were observed, nor was sister chromatid exchange increased.

Indomethacin treatment of acute pancreatitis. A controlled double-blind trial.

Thirty patients with acute pancreatitis were allocated to indomethacin suppositories, 50 mg twice daily, or identical-looking placebo suppositories for 7 days in a controlled double-blind trial. The groups of patients were not different with regard to age, sex, etiology, or number of Ranson criteria. The number of days with pain and number of opiate injections were significantly less in patients treated with indomethacin. The median values of serum amylase and serum calcium were not different before or at any day during treatment. Bleeding from the gastrointestinal tract was not seen.

Increased in vitro tetraploidy: a possible biomarker of non-heritable colorectal cancer?

In vitro tetraploidy (IVT+) in dermal fibroblast monolayer cultures has been studied in a series of patients with non-syndrome colon cancer and a control group to determine its value in identification of genetic predisposition for all colon cancers and its relevance to colon cancer occurrence on the basis of clinical history and pedigree data. Among 41 patients with colon cancer 18 (44%) had IVT+. In the control group 3 of 34 individuals (9%) showed IVT+. The difference is statistically significant (p less than 0.001). There was no correlation between a positive family cancer history, sex, age, or the presence of IVT+. Further studies using this possible in vitro biomarker may clarify the role of genetics in non-syndrome colorectal cancer.

Mandibular osteomas in colorectal cancer.

Orthopantomography of the mandible was carried out on 50 patients with colorectal cancer without known familial disposition. Twelve patients (24%) had osteomas, as against 5% in the control group (P less than 0.001). Since an increased occurrence of mandibular osteomas has earlier been demonstrated in cases of familial polyposis coli and the family cancer syndrome, we must conclude that genetic factors are presumably of more importance in the development of colorectal cancer than previously assumed.

The Danish Polyposis Register. Description of the methods of detection and evaluation of completeness.

A manual Danish register of patients with familial polyposis coli and their family members was established in 1971. The methods of collection of propositi, preparation of pedigrees, collection of call-up cases, and the organization of the register are described. A country-wide prophylactic proctosigmoidoscopic examination of first-degree relatives, aged 10 to 59 years, resulted in the detection of 42 call-up cases and by December 1982, 319 cases of polyposis were registered in 94 families. An evaluation of the number of collected propositi and call-up cases shows almost complete registration.

Mandibular osteomas in familial polyposis coli.

Orthopantomograms of the mandible were performed on 46 patients with familial polyposis coli having no clinical signs of Gardner's syndrome and on 46 control patients matched according to age and sex. Thirty-five patients (76.1 per cent) and two (4.3 per cent) controls had osteomas (P less than 0.0005). It is concluded that orthopantomography of the mandible is a valuable diagnostic supplement to prophylactic proctosigmoidoscopic examination of first-degree relatives of polyposis patients. Due to the frequent occurrence of mandibular osteomas in polyposis patients without clinically detectable extracolonic manifestations, it is suggested that "Gardner's syndrome" is no longer considered a clinical entity.
