We present a patient who had a left mastectomy for breast cancer and 3 years later developed intestinal obstruction due to metastatic spread to the small bowel. The small bowel follow through showed multiple stenoses of the small intestine leading to a variety of differential diagnostic considerations as metastatic spread from breast cancer to the small intestine has not been convincingly documented so far.

Cefsulodin (CFS), a new antipseudomonal cephalosporin, shows a potent antibacterial activity against Pseudomonas aeruginosa and some Gram-positive bacteria, whereas it shows low activity against many Gram-negative rods. Against clinical isolates of P. aeruginosa, CFS was about 10 times more active than sulbenicillin and carbenicillin, and had a similar activity to gentamicin and dibekacin. The CFS was administered by an intravenous bolus injection at a dose of 1 g to each of 14 patients operated for acute peritonitis with drainage or radical mastectomy with drainage to treat breast cancer. These cases included 3 of localized peritonitis due to perforative appendicitis, 3 of diffuse peritonitis due to perforative duodenal ulcer, 2 of panperitonitis due to intestinal obstruction and perforative sigmoid colon cancer, 4 of subacute cholangitis, localized peritonitis T-tube choledochal drainage due to choledocholithiasis, and 2 of breast cancer. Materials from drain exudate were taken at intervals with sterilized paper discs and CFS concentrations were determined by the paper disc bioassay method with P. aeruginosa NCTC 10490 as the test organism. Serum concentrations of CFS just after injection reached 135.4 +/- 66.1 micrograms/ml, and they were 2.7 +/- 1.5 micrograms/ml at 6 hours after injection. Concentrations in purulent exudates of patients with acute peritonitis increased quickly after intravenous bolus injections, and reached maximum levels relatively early after injection in cases 2 to 3 days after operation. In cases 10 to 13 days after operation, CFS levels were comparatively low and reached to peak levels at 4 to 5 hours after injection. Levels of CFS in purulent exudate tended to increase in proportion to the severity of symptoms, as did CFS levels in appendix wall. Pseudomonas spp. were not isolated in this study, but MICs of CFS were mostly around 1.56 to 3.13 micrograms/ml when clinically isolated Pseudomonas spp. were present at 10(6) cells/ml. Levels of CFS in infected exudate were higher than the above MIC values against Pseudomonas spp. Therefore, CFS were a useful drug for the chemotherapy against pseudomonal infections.

Metastatic tumors of the small bowel from extra-abdominal sites are rare. The primary tumors that have been reported are malignant melanoma, breast cancer, bronchogenic carcinoma, embryonal myosarcoma, and seminoma. We have presented a case of small bowel obstruction due to metastasis from esophageal cancer.

Retroperitoneal fibrosis is an uncommon disease of diverse etiology. Carcinoma of the breast is rarely considered as a cause of retroperitoneal metastasis or fibrosis. This paper describes five patients with retroperitoneal fibrosis secondary to breast cancer. The mean duration from initial diagnosis to onset of symptoms was greater than ten years. The patients had received a variety of treatments for breast carcinoma and had extensive metastatic disease. Presenting symptoms included abdominal, flank, or low back pain. Two had small bowel obstruction and four had ureteral obstruction. It is possible that with long-term survival this complication may be seen more frequently.

Colorectal cancer is the second most common malignancy of the adult population in the United States. It is exceeded only by lung cancer among males and breast cancer among females. Malignancies of the colon and rectum are responsible for approximately 12 per cent of all adult cancer deaths. These tumors appear as surgical urgency by intestinal obstruction for 15-20 per cent and by perforation for 3-8 per cent of all cases. It often occurs in elderly patients; in fact, urgent surgical operations are especially performed in patients older than seventy. The mortality rate for urgent surgical operation in elderly patients is about 32-54 per cent. This high mortality is even due to concurrent pathologies and particular locoregional and/or general alterations induced by tumor. The authors studied all patients older than 75 years affected by colorectal cancer and treated by choice or by urgency at Dept. of Surgery of the University of Perugia from January 1987 to February 1993 to individualize some clinical, anatomo-pathological and therapeutical significant characteristics about colorectal cancer in geriatric age.

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by hamartomatous polyps in the small bowel and mucocutaneous pigmentation. Patients with Peutz-Jeghers syndrome often present as surgical emergencies with complications of the polyps, such as intussusception, bowel obstruction, and bleeding. Recently an increased risk of malignancies has also been reported. This study was initiated to determine the clinical features of Peutz-Jeghers syndrome in Korean patients, with special attention to the development of malignancies. Thirty patients with Peutz-Jeghers syndrome were investigated; their median age was 23.5 years, and symptoms appeared at a median age of 12.5 years. Family history was positive in one-half of cases, and mucocutaneous pigmentation was observed in almost all patients (93%). The jejunoileum was the most frequent site of the polyps, and there were generally 10-100 polyps. Multiple laparotomies were performed in a substantial portion of the patients, due mainly to polyp-induced bowel obstruction, and the surgical interventions were begun at a relatively young age (average 21.4 years). Four cases of small-bowel cancer and one case of breast cancer were detected in probands, at a relatively young age (mean 36 years). Cancers of the small bowel, stomach, colon, breast and cervix were diagnosed in the first relatives of the probands. Close follow-up from an early age should thus be performed in patients with Peutz-Jeghers syndrome as they are at high risk of surgical emergency and development of malignancy.

Metastases are a common feature during the evolution of breast cancer. However, gastrointestinal metastases, and especially ceco-appendicular ones, are very rare. Melanoma however frequently metastasize in the gastrointestinal tract. Ceco-appendicular metastases do not display any specific signs in cancerous patients. These rare metastases must be considered in the diagnosis of right lower quadrant pain in cancerous patients. The main differential diagnosis includes neutropenic enterocolitis, acute appendicitis, malignant intestinal obstruction and perforation of the bowel. The morbidity of gastrointestinal complications in patients with metastatic cancer receiving chemotherapy is significant and surgery is often the only chance of survival. The major clinical decision is whether or not to operate.

The commonest sites for breast cancer metastases are the bones, lungs, liver, pleura, adrenals and central nervous system. However, although other sites have been reported, solitary metastases to the gastrointestinal tract are extremely uncommon. Widely disseminated gastrointestinal metastases may be found in up to 20% of patients. Although only 15% of patients with breast cancer will have the lobular variety, these make up the majority of patients with solitary gastrointestinal metastases. Here we present three cases where solitary lobular breast cancer metastases have been demonstrated to be the cause of bowel obstruction. In two cases of duodenal obstruction was demonstrated and in the third colonic obstruction. In all cases a focal extrinsic compression was found.

Metastatic involvement of the upper gastrointestinal tract from breast cancer has been reported in autopsy series as occurring in more than 15% of patients, usually associated with extensive systemic spread; clinical manifestations from such metastases have been described in less than 1% of cases. Lobular infiltrating carcinoma seems to have a different metastatic pattern than the ductal type, with an apparent predilection for the gastrointestinal tract. Metastatic presentation as an isolated intestinal obstruction without other signs of metastatic spread is extremely rare. We present a case of isolated duodenal metastasis from breast cancer, associated with intestinal obstruction, as the first sign of metastatic spread.

Although breast cancer most frequently metastasizes to the bone, lung, pleura, liver, adrenal glands and brain, it can also affect other organs such as the small bowel and ovaries, especially if the type of cancer is infiltrating and lobular. We present a case of metastases to the small bowel and ovaries from pleomorphic type infiltrating lobular breast carcinoma presenting as intestinal obstruction. Barium transit study revealed a stenosis in the jejunum and another in the terminal ileum at the ileocecal valve area. A flat formation in the area of the ileocecal valve was observed on endoscopy but the results of biopsy were negative, a fairly frequent finding due to the absence of infiltration of the intestinal mucosa. Pathological and immunohistochemical study of the intestinal and ovarian surgical specimens confirmed the diagnosis of metastases from lobular carcinoma of the breast, which was corroborated by breast biopsy.
