Deterioration in nutritional status occurs late in the progress of cancers at certain sites, but at all stages in patients with gastrointestinal cancer. Weight loss with decrease in body fat and muscle wastage, occurs to a varying degree. Superficially, the clinical condition resembles simple food deprivation. However, the derangements in metabolism are often and some patients show an elevated resting energy expenditure, disturbances of carbohydrate, fat and protein metabolism and generally, a failure to adapt to reduced food intake, which is characteristic of cachexia. Cancer cachexia then becomes characterized by signs of marked negative energy and protein balance, including hypoalbuminemia, weight loss, and anemia. On the other hand, toxohormone extracted from tumor tissues was considered as the main cause to produce cancer cachexia. However, it has become clearer that cytokines, e.g. cachectin/TNF, IL-1, LT and IFN gamma play an important role to produce cachexia. Patients who are malnourished have an incidence of postoperative complications double that seen in adequately nourished patients. The effectiveness of cancer-chemotherapy is also different in nutritional status of patients. Although in patients requiring hyperalimentation, enteral nutritional support may feasible and enteral feeding has a distinct metabolic advantage compared with parenteral feeding, there is a definite role for total parenteral nutrition in patients who have severe chronic radiation enteritis, side effect of chemotherapy, weight loss and malabsorption. Tentative weight gain and correction of hypoalbuminemia without improving patient survival may be expected by this intravenous hyperalimentation.

Twenty-eight patients underwent pelvic exenterations for gynecologic malignancies between June 1986 and June 1989. The postoperative fluid and electrolytes were managed by one of two regimens. One group of 10 patients was given concentrated 25% albumin infusion for the first 16 hr after surgery in addition to maintenance intravenous crystalloid solution according to ideal body weight. The second group of 18 patients received only a standard crystalloid solution. The albumin infusion group was found to have a more stable postoperative course as evidenced by less fluid boluses (P less than 0.01), fewer electrolyte bolus requirements (P less than 0.01), and easier management of blood pressure and urine output. There was a 50% decrease in total fluid requirement, a higher mean right atrial pressure (P less than 0.05), and a lower maintenance intravenous fluid rate (P less than 0.01). As a consequence, central hyperalimentation was started earlier (P less than 0.01) and the albumin infusion group left the Intensive Care Unit sooner than the non-albumin infusion group. There was not a single instance of clinical fluid overload with this slow infusion technique. Thus, concentrated albumin infusion was beneficial in the acute fluid management of these difficult patients.

The aggressive radiotherapy and chemotherapy used in conditioning regimens for children with leukaemia undergoing bone marrow transplantation (BMT) cause a severe catabolic state. Total parenteral nutrition (TPN) is indispensable in the management of these patients. 25 children with leukaemia undergoing BMT were studied to evaluate the efficacy of TPN and the value of anthropometric parameters and biochemical variables (albumin, retinol-binding protein and prealbumin) in monitoring nutritional status in the critical post-BMT phase. The complications of TPN were mainly metabolic, generally mild and easily controlled. The hyperalimentation solution and infusion line were not responsible for infection in any patient. The marked variations in anthropometric parameters and albumin expected in such patients were not observed in our children due to the nutritional support given. Prealbumin and retinol-binding protein showed statistically significant, positive variations (P less than 0.01), thus proving sensitive indices of the response to nutritional repletion.

Between October 1988 and May 1989, four cancer patients treated by broad-spectrum antibiotics developed a hemorrhagic diathesis induced by vitamin k (VK) deficiency. Activated partial thromboplastin time (APTT), prothrombin time (PT), factor II (FII) and protein induced by vitamin k absence of antagonist-II (PIVKA-II) were measured after administration of antibiotics and VK in all 4 patients. All these patients had been receiving intravenous hyperalimentation (IVH) and antibiotics for various infections. But all or them developed hemorrhagic diathesis within five days after the initiation of broad-spectrum cephem antibiotics (LMOX or CMNX). The abnormalities were 1) marked decrease of F II (6-18%), 2) prolongation of APTT (58.4-200 seconds), 3) prolongation of PT (7-21%), 4) marked increase of PIVKA-II (17-80 less than AU/ml). After being treated by intravenous administration of VK, hemorrhagic diathesis and abnormalities of coagulation tests except for PIVKA-II were corrected quickly in three evaluated patients. The measurement of PIVKA-II seemed to be useful to diagnose the hemorrhagic diathesis caused by VK deficiency in the patients during administration of antibiotics.

To investigate the efficiency of protein and carbohydrate absorption, we studied malnourished and well-nourished subjects during the first 72 hours of tube feeding. We furthermore investigated whether differences in absorptive efficiency existed between malnourished patients with and without nongastrointestinal malignancy. Twenty-one subjects starting tube feeding without edema or major organ failure and not on antibiotics (well-nourished controls = 7; malnourished = 7; malnourished with nongastrointestinal malignancy = 7) received 50 kcal/hr Osmolite continuously for 72 hours. Twelve of these subjects completed an additional 48 hours of study where they received 125 kcal/hr continuously. We performed hydrogen breath tests to assess carbohydrate absorption and determined stool nitrogen content to assess protein absorption. We also measured frequency of defecation, stool weight, and stool moisture content. The results of these tests failed to reveal statistically significant differences between the three groups in terms of protein and carbohydrate absorption, as well as failed to demonstrate the presence of diarrhea. We conclude that patients receiving an isoosmolar diet who are malnourished, or malnourished with nongastrointestinal malignancy, absorb carbohydrate and protein as well as well-nourished patients during enteral hyperalimentation.

Weight loss and cachexia are common characteristics associated with the cancer patient. Although the wasted appearance seems the same in each person, the causes are varied. Studying a patient's history and identifying surgical causes to weight loss or weight loss as a result of treatment complications assists in the consideration of nutritional support. Nutritional parameters combined with the oncology nurse's knowledge of the patient, disease process, and treatment side effects place the nurse in the position to help identify options for nutritional support. The oncology nurse's expertise assists in the decision making process, since it is often not appropriate to institute nutritional support in the inpatient setting nor extend it to the home situation. Objective assessment parameters for home parenteral nutrition assist the nurse in making some of these decisions. The conflicts that arise within the decision making process are usually not clearcut nor easily resolvable. Home parenteral nutrition brings to the forefront requirements and variables that are often not consciously addressed when hyperalimentation is instituted in the inpatient setting.

Sixty-eight semipermanent subclavian catheters were placed in 61 patients with gynecologic malignancies. The principal indicator for placement was chemotherapeutic administration. Other uses included blood transfusion, antibiotic infusion, and hyperalimentation. The minor complication rate of 21% included exit site infections and clotted, broken, and dislodged catheters. There were no acute surgical complications; i.e., bleeding or pneumothorax, but there was a 6% major complication rate, which included four cases of sepsis and a case of a broken intravascular catheter.

An investigation has been made with regard to the clinical picture of 87 terminally ill patients with lung cancer. It has yielded the following points. 1) Seven patients had been informed of their diagnosis. 2) Intravenous hyperalimentation was administered in 78 cases (90%), oxygen therapy in 68 cases (78%), and morphine in 35 cases (40%). 3) The most frequent cause of death in these patients was respiratory failure, due to progress of cancer, then infection, pleural, or pericardial effusion, or interstitial pneumonitis. 4) Psychic disturbances involved anxiety over breathing, depression, and delirium. In only 12% of the patients did the mental condition seem normal until death. 5) To deal with the dying patient's needs, it is necessary to establish proper treatment for the control of sensory dyspnea and for psychosocial support by a psychiatrist and other professionals for members of the family.

Recipients of autologous bone marrow transplantation (ABMT) for solid tumors need nutritional support to maintain their body weight (BW). Severe BW-reduction (9.9%) was noticed retrospectively in ten ABMT patients fed orally, despite intensive counseling or occasional tube feeding. A prospective, randomized study of hyperalimentation (25 g nitrogen (N) and 3400 nonprotein kilocalories) with total parenteral nutrition (TPN) or partial parenteral plus enteral nutrition by tube feeding (PPN/EN) was done in 22 patients. Nutritional assessment included balance measurements of N, Na, K, Cl, P, Ca, Mg, Cu, and Zn, and serial measurements of BW, serum albumin, prealbumin, and transferrin. Both regimens were effective in maintaining BW (maximum percent of change, 2.5) and N-balance. Blood products accounted for an additional N-intake of 13% in both groups. The TPN group had a higher dietary N-intake versus PPN/EN, a positive K balance but negative Ca, Mg, Cu, and Zn balances. More mineral supplementation was given in the PPN/EN group where positive K, Mg, and Zn balances were seen. Visceral proteins and IgG, IgA, and IgM levels were decreased on days 7, 14, and 21. Creatinine clearance increased significantly in both groups. Compared with TPN, the PPN/EN group showed a twofold number of patients with a positive blood culture, although this observation did not reach statistical significance and patients had fewer days of diarrhea (31.1% versus 54.3%, P less than 0.01). Hyperalimentation with PPN/EN is an acceptable alternative to TPN in the nutritional support of ABMT recipients.

A variety of devices is now available for venous access in patients requiring long-term infusions of chemotherapeutic agents, hyperalimentation solutions, blood products or antibiotics. All have advantages and disadvantages which may make the selection of one type of device appropriate under a given set of circumstances but inappropriate in another. Experience has shown that patients needing intensive therapy for hematologic malignancies are best served by lines that require minimal dissection for insertion, such as the Hickman catheter. Patients who are unlikely to hemorrhage at the time of insertion and who need only intermittent therapy can take advantage of the greater convenience and cosmetic appearance of a totally implantable port. Peripheral vein cannulation by means of fine silicone rubber catheters can be performed by trained intravenous nurses to provide access of intermediate duration without the expense and inconvenience of surgical insertion in an operating room.
