Three cases of perforated diverticulitis of the transverse colon are added to 19 case reports in the English literature. This unusual disease entity is usually confused with acute appendicitis prior to operation and with carcinoma of the colon during the procedure. The cause of these diverticula is unclear, and their clinical presentation resembles that of right-sided diverticula. Segmental resection of the transverse colon together with end-to-end anastomosis is the treatment of choice, except in the occasional instance of a large intra-abdominal abscess, when anastomosis may be deferred.

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.

The relationship between food intake and cancer of the large bowel was assessed by calculating the average intakes of foods, nutrients and dietary fibre in the different regions of Great Britain and relating these to the regional pattern of death from colon and rectal cancers between 1969 and 1973. No significant associations were found with the consumption of fat, animal protein or beer, nor with current estimates of total dietary fibre intake. Average intakes of the pentose fraction of total dietary fibres, and of vegetables other than potatoes, were negatively correlated with the truncated age- and sex-standardized death rates from colon cancer (r = -0.960 and -0.940). Specific components of dietary fibre may therefore inhibit colon carcinogenesis.

Glycoprotein synthesis and secretion were measured in short-term organ culture of normal and neoplastic colonic mucosa from 11 patients undergoing colectomy for colon cancer. Mucosal explants were incubated for up to 24 hr with [3H]glucosamine, which was incorporated into both explant and secreted glycoproteins. Structural and functional viability was documented by morphological studies that showed excellent preservation of architectural detail and biochemical studies that documented a steady increase in glycoprotein synthesis during 24-hr incubation. The major difference between normal and neoplastic mucosa was a 35% decrease (p less than 0.02) in the incorporation of [3H]glucosamine into tumor explants, as compared to the amount incorporated into normal explants from the same patient. The rate of secretion of radiolabeled glycoproteins into the medium did not differ significantly. Separation of explants into particulate and cytosol fractions showed that the overall decreases in glycoprotein synthesis in tumor explants was primarily due to a marked reduction in particulate glycoprotein synthesis in the cancer tissue.

The concept of second-look surgery was introduced by Wangensteen 25 years ago, and 17% of patients were reported to be converted to a cancer-free state. Instead of an arbitrary time interval for reoperation, serial CEA values were used as the indicator of colon cancer recurrence and second-look operation. Twenty-two retrospective and 18 prospective patients were evaluable. There was no operative mortality. The CEA Nomogram was used to determine whether the CEA change was significant. All patient-samples were analyzed in duplicate, stored, and compared with the most recent sample; therefore, each patient served as his own control. The prospective results emphasize the importance of minimizing the time delay between a significant change in CEA values and reoperation. Equally important are the frequency of serial determinations (every one or two months), a thorough understanding of the limitations of the CEA radioimmunoassay, and the clinical condition of the patient.

A personal series of 41 cases of carcinoma of the large bowel seen in Uganda during 7 years is presented. The relatively young age of the patients compared with the patients in Western countries is discussed. Diet probably played no role in the aetiology of the disease in this series. It is observed that in carcinoma of the rectum the lesion is usually low, necessitating resection of the rectum, which the patients frequently refuse.

A case of bilateral testicular metastases from carcinoma of the colon is reported. A review of the literature on secondary testicular tumors reveals their rarity and speculation is made as to the routes of metastases.

In 82 patients, a preoperative diagnosis of primary hyperparathyroidism has been established by means of transfemoral neck vein catheterization and measurement of serum immunoreactive parathyroid hormone (iPTH). Twenty-five of these patients have had cancer in other parts of the body but with no evidence of recurrence or metastasis. One patient had carcinoma of the colon with metastases, and four were members of families with multiple endocrine adenomatosis (MEA, Types I and II). In six other hypercalcemic patients, high levels of iPTH were found also in the effluent blood from cancer sites other than the parathyroid gland, secondary to ectopic hormone production or pseudohyperparathyroidism. In addition, a high serum level of iPTH was found in the superior vena cava of a seventh patient who had carcinoma of the breast but no clinical or radiological signs of recurrence or metastasis with the exception of an enlarged liver. This iPTH finding was interpreted as being, probably, the result of parathyroid adenoma in either the neck or the mediastinum. At the time of operation, a transcervical mediastinal search was made. Four normal cervical parathyroid glands were found; three were removed. Hypercalcemia persisted after operation, and the patient died. At postmortem examination, microscopic study revealed that the disease had metastasized to lungs and hilar lymph nodes. There was massive metastasis in the liver; the liver contained a large amount of iPTH. The results of these investigations suggest that (1) venous catheterization of the neck veins and the effluent blood from extraparathyroid tumors aid in identifying and localizing iPTH production; (2) primary benign hyperparathyroidism is not uncommon in patients with cancer, and its co-existence must be recognized; (3) high serum iPTH level in the superior vena cava may be found in patients with metastatic or primary cancer of the thoracic cavity; and (4) hyperparathyroidism may be the first hint of a familial multiple endocrine syndrome.

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 64 year old woman with a past history of panhysterectomy and oophorectomy for carcinoma of the body of the uterus (1950) and partial colectomy for carcinoma of the colon (1971), presented in 1972 with severe weakness of the proximal girdle muscles and histological evidence of polymyositis. A detailed search disclosed no tumor and she was treated with prednisone. Two years later, investigations for iron deficiency anemia revealed two polyps in the colon. Pathological examination of the resected colon disclosed two separate foci of adenocarcinoma and a number of adenomatous polyps. Three months later, further investigations for melena led to the discovery of a gastric carcinoma. Due to the extent of the tumor, she was subjected to gastrectomy. splenectomy, and excision of the tail of the pancreas, but died of postoperative complications. At autopsy, no residual cancer was detected, but a meningioma was found. The association of polymyositis with malignant tumors has been recognized for a long time, but only two previously reported patients have had more than one cancer. Although a causal relationship is difficult to establish, continued vigilance for neoplasms is advocated during the follow-up period.
