Over a 7 1/2-year period, 94 cancer patients presenting considerable operative risk were managed by total parenteral nutrition (TPN). All were nutritionally depleted, had obstruction to the gastrointestinal tract or had postoperative complications such as enterocutaneous fistulas, evisceration or intra-abdominal sepsis, which left TPN as the only means of achieving anabolism. When TPN was started preoperatively and continued post-operatively (28 patients--Group 1), no deaths or significant complications occurred. When TPN was first started after life-threatening complications had occurred (58 patients--Group 2), the mortality was 17.2%, so that a high incidence of recovery was achieved. When TPN was used in inoperable cachectic patients (8 patients--Group 3) to enable them to tolerate radiotherapy or chemotherapy, the mortality was 37.5%. This latter group is small, but TPN is worthwhile in selected patients where significant palliation and improvement in the quality of life can occur. With careful technique, risk of sepsis with TPN was no greater than in noncancer patients.

Cancer cachexia should no longer be a contraindication to adequate antineoplastic treatment. Current methods of nutritional assessment allow one to identify malnutrition and to follow the nutritional status of the patient throughout the cancer-management program. Enteral nutritional repletion and maintenance remain the ideal course of action, but the gastrointestinal tract is not always readily available or advisable for use; in such circumstances, intravenous hyperalimentation (IVH) may be indicated. The properly nourished patient better tolerates cancer therapy, experiences fewer complications of malnutrition (e.g., sepsis and poor wound healing), and has a better-functioning immune system than does his malnourished counterpart. This article reviews methods of nutritional assessment, delineates indications and techniques for nutritional repletion, and summarizes the results obtained.

Upon the plasmin digestion of human fibrinogen, an early cleavage product, which has been designated as fragment A, was isolated, and to study the action of plasmin in the circulation, radioimmunoassay for fragment A was carried out. This assay used rabbit immune serum obtained by injection of fragment A mixed with complete Freund's adjuvant, and fragment A was labeled with 125I using the Chloramin-T method. In 20 normal healthy donors its serum level was 3.57 +/- 1.62 microgram/ml (mean +/- SD), and it was increased significantly in certain diseases, such as acute leukemias, cardiovascular disorders, malignancies, renal failure, systemic lupus erythematosus and sepsis.

Review of the coagulation laboratory records and medical records at Memorial Sloan-Kettering Cancer Center over a three year period (1971--1974) revealed 89 patients with disseminated intravascular coagulation (DIC). The diagnosis of DIC was made if laboratory studies showed evidence of quantitative and qualitative changes in fibrinogen and significant thrombocytopenia. The patients included 19 with leukemia (17 acute), 3 with multiple myeloma, 15 with lymphoma, 46 with metastatic solid tumors, (10 lung, 9 breast, 8 gastrointestinal, 12 genitourinary, 7 miscellaneous) 4 with vascular tumors, and 3 without tumor. Other conditions which might have precipitated or initiated DIC such as gram-negative sepsis, liver impairment, or mucin secreting tumors were present in the majority of patients. Bleeding occurred in 75% of the patients and was fatal in 36%. Thromboembolism occurred in 22.5%. Thirteen percent were asymptomatic. Serum lactic dehydrogenase was elevated in over 75% of the patients at the time of, or subsequent to the occurrence of DIC. Treatment with heparin was helpful in only three of twenty patients. Eighty percent of the patients died within one to over 30 days of the onset of DIC. Post mortem evidence of DIC was present in 18 of 43 autopsies. Results of this study indicate that DIC is a frequent complication of a wide variety of tumors and that its occurrence causes morbidity and mortality in a significant number of patients. Treatment with heparin is of little help unless remission is induced and the precipitating factor(s) are reversed.

The clinical and pathologic findings of four cases of cystic nephroma (so-called "renal multilocular cyst") in four infants nephrectomized with the diagnosis of Wilms' tumor are presented. Each lesion consisted of an encapsulated mass composed of cysts separated by thin septa. Histologically the cysts were lined by epithelium, and the septa contained foci of immature metanephric blastema (abundant in one case and sparse in another). rhabdomyocytes and mature tubules. Neither embryonic ducts nor cartilage were seen. One cystic lesion was adjacent to a nephroblastoma which formed a separate nodule. No recurrences of metastases developed, and the only death was due to postoperative sepsis. These lesions are considered by some authors to be dysplasia, while others interpret them as benign neoplasms. Our findings and a review of the literature probably represent the differentiated counterpart of nephroblastoma.

A review was made of the presentation, treatment, and follow-up of 20 patients with adenoid cystic carcinoma and 12 patients with mucoepidermoid carcinoma of the bronchus who were seen at the Mayo Clinic during the 50 year period 1927 through 1977. Three forms of therapy were employed: complete surgical resection, radiation therapy alone, and radiation therapy after endoscopic removal of tumor tissue. Superior results were obtained in the group with adenoid cystic carcinoma, when complete resection was possible. Significant survival and palliation of sepsis was achieved with subtotal resection. The mucoepidermoid carcinomas in this series were classified on the basis of histologic differentiation. Mucoepidermoid carcinoma of Grade 1 was managed by conservative pulmonary resection. Mucoepidermoid carcinoma of Grades 2 and 3 showed a greater propensity for malignancy. Widespread dissemination caused death with unresectable high-grade mucoepidermoid carcinomas of Grades 2 and 3.

A subpopulation of human lymphocytes bearing receptors for the Fe portion of IgG causes lysis of nucleated target cells in the presence of antibody. The reaction is known as antibody-dependent cellular cytotoxicity (ADCC) and the effector cells have been called killer (K) cells. We have measured K cell activity quantitatively in the peripheral blood of cancer patients using 51Cr labeled murine mastocytoma target cells and hyperimmune rabbit antimastocytoma antibody. ADCC was the same in males and females, was not affected by eating, smoking or the presence of infections, but was decreased in those over 65 years, during pregnancy, and in those with cachexia, or severe sepsis associated with nonmalignant diseases. It was normal in those with cancers being treated for cure and in those with benign diseases, but was decreased in those with advanced cancers. Operation did not produce a significant change in those who were not immunodepressed; in those who were immunodepressed before operation it caused a significant decrease maximal by the fifth day with recovery by the 15th day. Radiotherapy caused a decrease in K cell activity, maximal at 4 weeks, that persisted for 12 weeks with recovery after that time in those who did not have residual tumor. The values did not return to normal in those who had persistent tumor or distant metastases.

Hemorrhagic gastritis is the most frequent cause of upper gastrointestinal bleeding in patients with cancer. A study was undertaken to evaluate the clinical course of 87 patients, in a cancer hospital setting, with hemorrhagic gastritis associated with stress, exogenous gastric irritants and the combination of the two. The average number of blood transfusions was four times higher and the average duration of bleeding was twice as long in stress patients as in patients without stress. Fifty-four per cent of stress patients died, whereas all patients survived in the group without stress. Although there were no statistically significant differences, patients with the combination of gastric irritants and stress tended to bleed longer and have a higher mortality than patients with stress alone. Over two-thirds of the deaths were ascribed to associated stress risk factors such as sepsis, multiple organ failure and advanced cancer and not to gastrointestinal hemorrhage.

This brief review of abdominal emergencies is by no means encyclopedic. Indeed, it simply reflects the multiplicity of problems that can occur and suggests the need for a high index of suspicion and an optimistic attitude toward their solution. In addition, the surgeon must keep in mind the fact that cancer patients may also suffer acute abdominal distress from extra-abdominal causes such as pneumonia, myocardial infarction, diabetes mellitus, and hematologic abnormalities such as porphyria or sickle cell anemia. Inflammatory bowel disease, pelvic inflammatory disease, acute hepatitis or other similar problems more commonly seen in general hospital populations may also develop. Consultations for an acute condition of the abdomen in patients receiving marrow-suppressing chemotherapy are challenging problems and repeated examination every few hours is required to detect subtle changes. Hypovolemia, sepsis, confusion and unexplained metabolic acidosis may be the only criteria for surgical exploration. An unnecessary operation in a leukopenic and thrombocytopenic patient is indeed risky, but failure to drain an occult abscess or resect a perforated segment of bowel is always lethal. An additional consideration is the likelihood of response to further treatment of the underlying disease. Unless further effective therapy is unavailable, pessimism is unwarranted.

Because of the persistently high mortality from sepsis in cancer patients, a retrospective study was designed to identify the causative organisms and to determine the factors affecting the outcome of sepsis. A total of 84 episodes of septicemia in 61 children with cancer were studied. The more frequently isolated organisms were: Staphylococcus aureus (21.4%); Escherichia coli (18%); Klebsiella (7.1%); Pseudomonas (6%); and Bacteroides fragilis (6%). Other isolates included Proteus, Serratia, Acinetobacter, hemolytic Streptococcus, and Bacillus cereus. In 10.7% of septic episodes, mixed bacterial infections were documented. Twenty-four (28.6%) resulted in death; in 13 (54%) death occurred within 24 hours after admission. The fatality rate was high in cases associated with absolute polymorphonuclear leukocyte counts of less than 100/cu mm, in neoplastic relapse, and when infection with gram-negative, anaerobic and mixed bacterial flora occurred.
