The records of 126 patients with adenocarcinoma of the colon and rectum who presented with liver involvement were reviewed. Prognosis was determined by the amount of metastases to the liver, which was usually extensive of ascites or a raised alkaline phosphatase level was present. The longest survival period was achieved with resection of the primary tumor along with hepatic lesions confined to a single lobe, especially those due to direct tumor infiltration. If liver deposits were found bilaterally, palliative resection of the primary lesion relieved intestinal symptoms. This may also prolong the survival time, because a fixed primary tumor appeared to diminish the outlook among patients with comparable liver disease. Palliative resection in the presence of ascites resulted in a high mortality, and the survival rate was no better than that after diversion procedures. We recommend resection without anastomosis for carcinoma of the rectosigmoid in patients with ascites and unresectable secondary lesions of the liver.

A 65-yr-old man with hepatic metastases from adenocarcinoma of the colon treated with hepatic arterial infusion of 5-fluoro-2'-deoxyuridine and radiation therapy, presented with major gastrointestinal bleeding from an endoscopically documented giant duodenal ulcer with a portion of the hepatic arterial catheter visible in the ulcer crater. A penetrating giant duodenal ulcer was confirmed during an operative procedure. This patient with giant duodenal ulcer penetration associated with an operatively implanted arterial infusion catheter represents an unusual complication of this form of chemotherapy for hepatic tumors.

Forty-two patients with adenocarcinoma of the colon, who received surgery between 1975 and 1978 and were to found to have pericolonic fat infiltration and lymph node metastases, were analyzed for disease free period and overall survival. Twenty-one patients had received post-operative X ray therapy, and post-X ray therapy intravenous 5-Fluorouracil adjuvant therapy. Twenty-one patients, matched by age, sex, ethnic origin and site of disease were untreated. The 5 year survival rate for the treated group was 65% compared with 36% for the control group (P greater than 0.2). At 5 years 55% of the treated group were disease free but only 12% of the control group remained disease free (P = 0.04). The significance of this work needs to be established by a randomized and prospectively controlled clinical trial.

Sixty-five patients with adenocarcinoma of the small intestine were encountered over a 31 year period. The duodenum was the most common location, with a decreasing frequency distally. Associated malignancies were present in a fourth of the patients. Presenting signs and symptoms were vague and related to either obstruction or bleeding. Barium contrast examination and endoscopy for duodenal tumors were the primary diagnostic modalities. Curative treatment was wide resection of bowel and mesentery for jejunal and ileal tumors and pancreaticoduodenectomy for duodenal tumors. Favorable prognosticators included jejunal location, absence of nodal metastases, and a well-differentiated grade. Stage for stage, the prognosis of patients with adenocarcinoma of the small intestine parallels that of patients with adenocarcinoma of the colon. With greater awareness of this tumor, it is possible that earlier detection will lead to improved overall survival.

Sixty-two patients less than 40 years of age were admitted with adenocarcinoma of the colon and rectum between 1967 and 1981 at the Methodist Hospitals of Memphis. These represented 3.2 per cent of a total of 1909 patients with the disease during the same time period. Eighty-one per cent presented less than 6 months after onset of symptoms; pain and bleeding being the most common complaints. Inflammatory bowel diseases and polyposis were uncommon. Fifty-eight per cent of the lesions were within reach of the sigmoidoscope. Localized disease was present in 37.9 per cent, with one-third presenting with distant metastases. Sixty-five per cent were considered curable at initial laparotomy. Only 2 per cent of the lesions were well differentiated, and mucin production was noted in 32.3 per cent of the specimens compared to 8.6 per cent in the total group. Vascular invasion was noted in 24 per cent and perineural invasion in 11 per cent. Five-year survival was only 17.6 per cent, although this increased to 33 per cent in those undergoing curative resection. Survival in the total group of 1909 patients was 35.5 per cent at 5 years. The poorer survival in the young patients does not seem to be on the basis of delay in diagnosis, premalignant states, or distribution of lesions, but rather it reflects an inherently more virulent lesion. This impression is supported by a greater incidence of mucinous tumors (a poor prognostic indicator) and higher incidence of advanced disease, especially in the second and third decades.

Six patients from one family and one solitary patient with juvenile polyposis coli are described. The histological changes in colonic polyps formed a spectrum from juvenile polyps, through focal to extensive adenomatous change, to adenocarcinomas. One patient aged 49 years had an adenocarcinoma of the colon and in another, aged 33, with rectal polyps and metastatic cancer this was suspected although the primary tumour was not located. Two additional patients, aged 19 and 41 years, had severe adenomatous dysplasia in a juvenile polyp. Four patients also had gastroduodenal polyps. The present findings clearly contradict the previous view that juvenile polyposis coli is not premalignant and only rarely needs surgical treatment. As other recent reports also describe frequent occurrence of neoplastic changes in juvenile polyps, colectomy, and ileorectostomy at the age of about 20 years is recommended as the treatment of choice for juvenile polyposis coli, as in patients with familial adenomatosis coli. Follow up should ideally include gastroduodenoscopy and inspection of the rectal remnant at regular intervals.

Twenty patients with Stage Duke B or C adenocarcinoma of the colon or rectum who have undergone radical surgical resection and demonstrated rising serum carcinoembryonic antigen (CEA) during follow-up are the subject of this study. In all cases, while there was a continuous and progressive elevation of serum CEA, CT examination of the abdomen and pelvis was performed. Abnormal CT findings were demonstrated in 19 patients and included pelvic mass, liver metastases, and periaortic or mesenteric lymphadenopathy. There was one normal CT scan in a patient who subsequently developed metastases in the sacrum. Based on the observations in these patients, it is concluded that in routine follow-up after colorectal surgery, rising serum CEA should be considered a warning sign and warrants additional investigation by CT.

The effect of chemotherapy on bony metastases from adenocarcinoma of the colon was investigated by quantitative skeletal imaging over a two-month interval. The quantitative skeletal imaging results correlated with conventional blood chemistry results over this time period. While chemical assay techniques furnish an average value of lesion response, the quantitative bone scan represents a method for individual lesion analysis. This methodology has the potential to provide a better understanding of metastatic bone disease therapy.

This paper reviews the clinical characteristics of a group of patients in whom unsuspected primary adenocarcinoma of the colon presented with signs and symptoms of a primary ovarian neoplasia. In most patients, the ovaries were removed, the correct diagnosis was established at a later time, and a second surgery for resection of the primary adenocarcinoma of the colon was then performed. Preoperative use of colonoscopy or barium-enema examination would have helped. We compared these patients to a group of patients with similar clinical characteristics, but in whom the ovarian metastases were clinically apparent months after the resection of a primary colorectal cancer. We found that, in both groups, age of the patients, anatomic distribution of the primary tumor, histologic differentiation, serosal or mesenteric lymph node tumor involvement, and timing of the oophorectomy in relationship to removal of the primary colorectal tumor did not affect the overall survival. Once ovarian metastases were documented, patients died regardless of treatment, approximately 16 1/2 months after the diagnosis.

The progression from normal colonic mucosa to invasive adenocarcinoma of the colon with lymph-node metastases was documented in Sprague-Dawley rats receiving 30 mg of N-methyl-N-nitrosourea via intrarectal injections. Histologically, these tumors closely resemble human colonic cancer. This model is predictable and reproducible. It offers a genetically nonidentical rat model for the development of cancer biology and therapy models.
