A 39 year-old patient with cholangiocarcinoma and pre-existing ulcerative colitis was successfully treated by orthotopic liver transplantation. He was given low doses of prednisone and azathioprine and survived for more than 9 months, dying with tumour metastases, thrombosis of the inferior vena cava and an intra-abdominal abscess. At autopsy the homograft showed little evidence of rejection. Preoperatively the patient had septicemia. Removal of his liver was difficult. The discrepancy between donor and recipient in size of blood vessels and the presence of two hepatic arteries in the donor caused problems during the vascular anastomoses. During the operation cardiac arrest occurred. Postoperatively there were several medical and surgical problems, including intraperitoneal and gastrointestinal hemorrhage, paralysis of the right dome of the diaphragm, sinus bradycardia, massive diuresis, peroneal nerve palsy, and one major and three minor episodes of rejection, which were reversed by giving pulse doses of methylprednisolone intravenously.

The first case of adenocarcinoma of the transverse colon and splenic flexture during pregnancy associated with ulcerative colitis is reported. The patient presented with perforation and widespread metastatic disease. After 10 years' duration of symptoms of ulcerative colitis, the risk of coexisting cancer of the colon is 3 to 5% each year. As ulcerative colitis frequently coexists with pregnancy, the obstetrician needs to be alert to the potential for malignant changes in these patients. With the addition of this patient, there are now 18 reported cases of cancer of the colon during pregnancy. These 18 cases are reviewed especially as to management, outcome of the pregnancy, and prognosis.

A 41-year-old female with a history of total ulcerative colitis for 15 years is presented. After eight years, she was enrolled in a colonoscopic surveillance program with regular examinations every second year and with biopsy sampling for histologic assessment of dysplasia as well as for flow cytometric analysis. Neither dysplasia nor DNA aneupoloidy developed during the course of the follow-up, but, after seven years, the patient developed a rapidly growing malignant stricture in the lower rectum. At the time of diagnosis, a local gluteal metastasis was found. Following preoperative radiation therapy, laparotomy disclosed a rectal cancer with local growth in the pelvis. Despite an attempt to perform curative surgery, the patient deteriorated and died within four months after the diagnosis. The carcinoma was of a poorly differentiated, mucinous, signet ring cell type, and DNA analyses of both the tumor and its metastases were diploid. Retrospective analyses of mucin content in colonoscopic biopsies showed a gradual shift from sulfated mucin to sialomucin. This case underlines the fact that even rigorous follow-ups offer no absolute guarantee against incurable malignancy in surveillance programs for ulcerative colitis despite the inclusion of DNA analyses.

A 62-year-old man with a 20-year history of chronic ulcerative colitis and a 9-year history of primary sclerosing cholangitis (PSC) underwent orthotopic liver transplantation because of symptoms related to PSC and cholangiographic features compatible with a biliary neoplasm. Study of the excised liver revealed papillary mucosal lesions in the common hepatic duct and the right and left hepatic ducts as well as cholangiectases and other features typically associated with PSC. The papillary lesions consisted of abundant fibrovascular stroma covered by biliary epithelium with low-grade and high-grade dysplasia. Some periductal glands were also dysplastic. These features distinguished papillary dysplasia from classic biliary papillomatosis. Only one focus of microinvasion was found; there were no metastases. Among 60 cases of PSC in whom the entire liver could be studied after orthotopic liver transplantation, this was the only instance of unequivocal dysplasia. However, in one specimen, papillary hyperplasia was found. Detailed macroscopic and microscopic rereview of 23 livers from our patients with the longest history of PSC (range, 5-24 years) failed to reveal any additional cases with dysplasia. It is concluded that (a) papillary mucosal lesions in PSC may represent papillary dysplasia without invasion; (b) these lesions may evolve from papillary hyperplasia; (c) the process may be largely, if not entirely, in situ; and (d) the prevalence of dysplasia and carcinoma of bile ducts may be less than the 7%-9% reported in the literature for malignancies associated with PSC.

Fifty-two patients with ulcerative colitis and colorectal cancer undergoing colectomy at the Mount Sinai Hospital between 1973 and 1988 were studied retrospectively to determine the correlation of age, sex, duration of colitis, tumor location, number of cancers, tumor differentiation, colloid content, presence of signet ring cells, Dukes' classification, and DNA ploidy with survival. The mean age was 45 years, with a mean duration of colitis of 21 years. Five patients (10%) had Dukes' A lesions, 17 (33%) had Dukes' B lesions, 17 (33%) had Dukes' C lesions, and 13 (25%) had distant metastases. Thirty patients (58%) had well- or moderately differentiated tumors, whereas tumors were poorly differentiated in 22 (42%). Twenty-eight patients (54%) had colloid tumors, and, in 14 (27%), signet ring cells were present. Thirty-one patients (60%) had nondiploid tumors. Actuarial analysis revealed that the 5-year survival rate was significantly worse for patients with nondiploid tumors (76% versus 32%). When stratified by stage, only patients with Dukes' C lesions showed a significant difference in survival for diploid versus nondiploid tumors. Multivariate analysis showed that the Dukes' classification was the best prognostic indicator, followed by tumor differentiation and DNA ploidy. Tumor location, colloid content, number of cancers, duration of disease, age, and sex did not correlate with the prognosis.

Results after 55 colectomies are reported in the period from 1962-1986. The surgical intervention was indicated by ulcerative colitis in 19, Crohn's disease in 18 and familial polyposis of the colon in 18 cases. 37 total colectomies, 12 subtotal colectomies with ileorectal anastomosis and 6 colectomies with a remaining terminal closed stump of the rectum were performed. During the period of observation postoperative lethality decreased from 37% to 6%. Death was most frequently caused by thromboemboli and peritonitis. In 44% of the patients ill with familial polyposis malignant degeneration could be observed. 3 died by generalized metastases. Metabolism of protein, lipid and electrolyte showed no essential disturbances after colectomy. Intestinal assimilation was nearly standard. More difficult is social reintegration.

The management of large carcinoid tumors of the anorectum is controversial. Most carcinoid tumors of the rectum and anus are early lesions, adequately treated by local excision. However, because of their relative rarity, the number of advanced cases seen at most institutions is small. Forty-three patients with anorectal carcinoid tumors were treated at our institution between 1960 and 1988 with complete follow-up. The median age of onset was 56 years. Eleven patients had no symptoms and the tumor was detected incidentally in eight additional patients with other diseases. Twenty tumors were larger than 2 cm in diameter and all patients had symptoms. Eight patients had another malignancy and three patients had ulcerative colitis. An association between ulcerative colitis and rectal carcinoid tumors is not widely appreciated. Eighteen tumors were treated by local excision, 16 by radical surgery, and nine underwent only biopsy. With complete resection of the primary lesion, local recurrence was never a problem. The median survival from diagnosis was 38 months in this series and 23 patients died of disease. After detection of metastases, the median survival time was 10 months. Tumors more advanced that T2 or larger than 2 cm in diameter were always fatal. All 13 patients with involved lymph nodes died of metastatic disease, with a median survival of 10 months, although one lived 9 years. Advanced rectal carcinoid tumors are aggressive malignancies. Adequate local excision controls regional disease but rectal carcinoid tumors are cured only when they are discovered before the T3 stage, measure less than 2 cm in diameter, and when lymph nodes are not involved. Consequently if a local excision permits complete resection, radical extirpative surgery will provide little benefit.

We describe a case of a tumour of the sigmoid colon with hepatic metastases in a patient with previously documented ulcerative colitis. A diagnosis of metastatic vipoma was made on the basis of high plasma levels of vasoactive intestinal polypeptide (VIP). Profuse diarrhoea and profound metabolic upset were corrected by the use of a somatostatin analogue SMS 201-995, whilst conventional cytotoxic therapy produced a significant tumour response with return of the plasma VIP level to normal.

Since 1977, 196 patients (177 with ulcerative colitis and 19 with familial polyposis) have undergone colectomy, mucosal proctectomy and endorectal ileal pull-through with or without an ileal reservoir (PTR) at UCLA Medical Center. Fourteen of the patients (7.1 per cent) had carcinoma of the colon or rectum at the time of operation; 12 had colitis and two, polyposis. Another 40 patients had mucosal dysplasia. Only five of the 14 patients with carcinoma were diagnosed before operation despite close surveillance by gastroenterologists. The mean duration of colitis before the diagnosis of carcinoma was made was 17 years; the mean age that the carcinoma was identified was 38 years. Eleven of the 12 patients with colitis had universal involvement. Two patients with colitis and carcinoma who underwent colectomy and PTR died a mean of 30.5 months postoperatively of metastatic disease. Twelve patients with carcinoma (ten with colitis and two with polyposis) are alive a mean of 29 months postcolectomy and PTR; two of these have received chemotherapy. The low mortality (0.4 per cent) and good clinical results after colectomy and the PTR procedure and the unexpectedly high incidence of carcinoma and mucosal dysplasia among patients referred for operation suggest that surgical treatment should be considered at an earlier stage than the current general practice, particularly in patients at high risk (mucosal dysplasia, pancolitis and duration of more than ten years).

To assess prognostic factors in patients who develop colorectal cancer before the age of 40 years, a 30-year experience from 1956 through 1985 was reviewed. There were 50 patients ranging in age from 7 to 39 years. Five cases were associated with either ulcerative colitis (2) or familial polyposis (3). The most common presenting symptoms were abdominal pain (66 percent), hematochezia (60 percent), change in bowel habit (41 percent) and weight loss (30 percent). On pathologic staging (N = 44), only 14 of 44 (31 percent) had a Dukes' stage A or B lesion, 20 (45 percent) had Dukes' stage C, and the remaining 10 (23 percent) had distant metastases at the time of surgery. Five-year survival rate was 28 percent with a disease-free survival rate of 18 percent. Median survival was only 28 months. Negative prognostic factors were Dukes' stage C/D (P less than .001), symptom duration of longer than 3 months (P = .01), noncaucasian ancestry (P = .01), and poorly differentiated histology (P = .06). In contrast to older patients with colorectal cancer, only 1 of 30 (3 percent) patients with stage C D disease was disease-free at 5 years. In view of the poor survival rate associated with both delay in diagnosis and the presence of advanced disease, it was concluded that young patients presenting with the symptoms listed above need early, aggressive evaluation for possible colorectal cancer.
