Ninety-nine black colorectal cancer patients and 280 matched controls from hospitals and multiphasic health checkup clinics were interviewed about past dietary habits and other traits. The colon cancer cases tended to report less frequent use of foods with at least 0.5% fiber content than did their controls. This relationship, though small, showed a consistent dose-response gradient, appeared in both case-hospital control and case-multiphasic health checkup control comparisons, and could not be accounted for by the effects of other variables. Colon and rectosigmoid junction cancer patients tended to have eaten foods with at least 5% saturated fat somewhat more often than controls. When consumption of these two groups of foods was considered in combination, significantly more colon cancer patients than controls reported a high saturated fat foods-low fibrous foods eating pattern, as opposed to a low saturated fat foods-high fibrous foods diet. Statistically significant excesses of the following traits were also reported by the colorectal cancer patients: prolonged cigar smoking in men, nulliparity in women, and history of colorectal polyps.

Two cases of irradiation-associated carcinoma of the colon are reported and the literature reviewed. The clinical courses and operative difficulties in treating these patients are emphasized. The necessity for life-long follow-up examinations with proctoscopic and barium-enema evaluations in high-risk patients is stressed. Irradiation-associated carcinoma of the colon occurs almost exclusively in women, but should be investigated in patients of either sex who live for long periods after pelvic irradiation.

A case of an undoubted squamous-cell carcinoma arising at the hepatic flexure in the colon of a middle-aged man is reported. Review of the literature and exclusion of cases not strictly comparable suggest that pure squamous-cell carcinoma of the colon is rare, this being only the fifteenth such tumor reported, and only the second recorded case of such a tumor of the hepatic flexure. Possible pathogenesis is suggested.

Established cancer in the liver can, in selected patients who have a good arterial circulation in these tumors, be effectively treated by intrahepatic artery radioactive yttrium-90 resin microspheres. Even in unselected patients treated in the last five years by the author, 17 of 25 patients treated have had good objective regression of cancers, improvement of symptoms and prolongation of life. Treatment is relatively simple and associated with few side effects. For adjuvant therapy of colon cancer having positive nodes (Dukes C), internal radiation therapy of the liver is best done with Phosphorus-32 Colloid passed through the circulation of the gut to be effectively and homogeneously trapped by the Kupffer cells of the liver. Four such patients have been subjected to a pilot study--three of the four are doing well without significant side effects and no evidence of liver cancer after two years. When the fourth died of brain metastases, he too had less liver cancer than would be expected.

Of 765 patients with disseminated metastatic carcinoma of the colon and rectum treated at Memorial Sloan-Kettering Cancer Center during the ten-year period 1960--1970, 53 (6.9 per cent) had skeletal metastases. Of these, 14 (1.8 per cent) had osseous metastases only. In one case the osseous lesion was the first symptom of a cancer of the sigmoid colon, and one patient had metastasis in the fibula from a primary rectal cancer. In our series the incidences of osseous metastases were 8.9 per cent from rectal carcinoma and 5.1 per cent from colonic carcinoma. The mean period from manifestation of skeletal metastasis to death was 13.2 months.

We have reported long-term results in the cases of 42 patients following total colectomy and ileorectal anastomosis for inflammatory bowel disease. In this group, 35 patients had Crohn's disease and seven had ulcerative colitis. Five of those seven patients with ulcerative colitis had carcinoma of the colon at the time of colectomy. A diverting loop ileostomy was constructed in 14 of the 35 patients who had Crohn's colitis at the time of operation, and none of these patients had any anastomotic leakage either before or after the ileostomy was closed. However, there patients with Crohn's colitis in whom anastomotic leaks developed postoperatively; all three patients died. In the group with ulcerative colitis, one patient had an anastomotic leak but there was no operative nortality. Of the 29 patients with Crohn's disease followed for one to 18 years, 12 (41 per cent) developed recurrences in the ileum and/or rectum, and seven of these patients had to have their anastomoses taken down.

Two patients had duodenocolic fistulas, each following a carcinoma of the colon in the area of the hepatic flexure that had perforated into the duodenum. The first patient was treated by a radical pancreatoduodenectomy with right colectomy; the second by subtotal colectomy with excision of the duodenal wall and suture. Both patients are alive and without evidence of recurrent disease. In addition, the first patient had two other primary carcinomas, in the cecum and in the stomach, and the second patient had another primary in the sigmoid. The definitive procedure had to be adjusted to encompass all lesions. The radical operation in one stage seems to be the preferred procedure and certainly is most satisfactory as a cancer operation. Our patient treated by this procedure has survived more than 11 years. An intestinal fistula related to colonic carcinoma, evan though rare, should not be considered as a separate entity. Treatment of the cancer with an en-bloc resection of the communicating organs should be employed if possible.

A retrospective analysis of data from 69 patients treated by Hartmann's operation between 1981 and 1991 determined prognostic factors for colon continuity re-establishment and the mortality of this second intervention. The 15 patients who died during the first month after the Hartmann's operation were excluded from the study, the 54 survivors including 32 men and 22 women, mean age 68 +/- 12 years (range 19 to 87 years). The initial indication for surgery was: complicated sigmoid diverticulis (n = 26), cancer of colon (n = 14) or other site (n = 14). Colon continuity was re-established in 23 patients (42.6%), including 15 men and 8 women, mean age 60 +/- 10 years (range 38 to 78 years). In this latter group, 82.6% of the patients were under 70 years of age, indicative of a significant effect of age (p < 0.001) on re-establishment of continuity. Secondary anastomosis was obtained in 65.4% of cases of complicated sigmoid diverticulitis, whereas re-establishment of continuity was possible in only 7.1% of colon cancer patients (p < 0.001). The mean duration prior to re-establishment was 4.8 +/- 1.6 months (range 2.5 to 9 months). Morbidity was high (47.8%) and mortality 4.3% (1 patient). Hartmann's operation remains indicated for stages III and IV of complicated sigmoid diverticulosis, as well as for other benign affections (volvulus of sigmoid, perforation of sigmoid following injury), although it must be recognized that the possibilities of re-establishment are limited more in elderly patients and that fewer patients with colon cancer can benefit from the procedure. A period of 3 to 4 months appears sufficient to allow healing of the inflammatory phenomena of the initial operation, without the development of excessive retraction of the rectal stump.

We describe the clinical and pathologic features in four extended kindreds that are consistent with the hereditary flat adenoma syndrome (HFAS). This colon cancer susceptibility disorder is believed to be inherited as an autosomal dominant. The principal phenotypic marker is multiple colonic adenomas (usually less than 100), with a tendency for proximal location. The majority of these adenomas are flat or slightly raised and plaquelike, as opposed to polypoid. Colon cancers have typically developed in middle age and show no unusual histologic features. There are a variety of extracolonic manifestations, including adenomas and carcinomas of the small bowel and fundic gland polyps. The HFAS is contrasted with hereditary nonpolyposis colorectal cancer and familial adenomatous polyposis (FAP) and shown to be distinct from both in the numbers and distribution of colonic adenomas and the typical age of cancer diagnosis. The clinical implications of these findings are discussed. Given its linkage to the FAP locus on 5q and the phenotypic parallels between HFAS and FAP, we conclude that HFAS is a variant of FAP.

Methods of morphological, histochemical and immunohistochemical analyses were used to further characterize differences between tumourous and adjacent grossly normal tissues in chemically-induced colon cancer in rats. Colon tumors were induced by the treatment of rats with 1,2-dimethylhydrazine or with N-methyl-N'-nitro-N-nitrosoguanidine alone or with subsequent treatment with deoxycholic bile acid. Tissues were studied morphologically (for the presence of goblet cells in the colon crypts, and the extent of infiltration of lymphocytes into the crypts and between them), histochemically (for the presence of positive reaction to neutral and acid mucopolysaccharides) and immunohistochemically (for the presence of tissue polypeptide antigen). All data were evaluated quantitatively, and index of tissue damage was calculated for both tumorous and non-tumorous tissues. Significant morphological differences were found between tumorous and adjacent apparently normal tissue. Histochemically and immunohistochemically, both types of tissue reacted very similarly to exposure to the carcinogens. Index of damage was significantly different from normal untreated colon in both kinds of tissue. It was suggested that precancerous state in tissue adjacent-to-tumor could be detected using the combination of these methods.
