The combination therapy with natural type human tumor necrosis factor (n-TNF; MHR-24) and human lymphoblastoid interferon-alpha (n-IFN-alpha; MOR-22) was investigated for antitumor effect against renal cell carcinoma in a multiclinic cooperative study throughout Japan. The "Response criteria of Japan Society for Cancer Therapy" were followed for the handling of subjects and the evaluation of antitumor effect. MHR-24 was administered at a daily dosage of 5,000-10,000 JRU by intravenous drip and MOR-22 at a dosage of 5,000,000 IU daily was administered intramuscularly at the same time. Both drugs were administered for 4 weeks or longer. A total of 36 patients were enrolled as subjects in the study. None of them were classified as ineligible. Five patients, were classified as imperfectly evaluable, and 31, as evaluable for the results of treatment. The responses in the evaluable patients were partial response (PR) in 4 patients, minor response (MR) in 3 patients, no change (NC) in 14 patients and progressive disease (PD) in 10 patients, with a response rate of 12.9%. Adverse reactions to the therapy were investigated in all 36 patients. The frequent subjective and objective reactions that occurred were fever, rigors and shivering, anorexia, and generalized malaise, and the frequent abnormal laboratory findings were leukopenia, thrombocytopenia, elevation of GOT, and elevation of GPT.

In 1988, Shafik et al. presented their first attempt to apply cytostatics in the treatment of pelvic malignancies. Experimentally and clinically, they studied the anal route for administration of methotrexate, and their first results showed that higher concentration of drugs can be achieved in the bladder wall compared to that in serum. Since December 1988, we have been engaged in experimental and clinical investigations of the possibilities this method might reveal. Experiments with animals have proven that submucosal injection of the cytostatic agent does not induce local changes. The clinical trial on 20 patients with tumors of stage T2-T4 has not shown side effects, either local or systemic. The treatment was well tolerated by the patients. Anorexia has been reported in 3, elevated temperature in 2 and leukopenia in 4 of 20 patients. Complete response has been documented in 3 (15%), partial response in 3 (15%), stabilization in 5 (25%) and progression of the disease in 9 (45%) of the patients. Mean duration of remissions was 10.3 months (range 9-12). The distribution of submucously injected contrast medium into the anorectal area has been studied by computerized tomography in 4 of the patients. Although our results do not support the original estimates of the inventors of the method, its ease of application, the possibility of out-patient administration and negligible side effects are sufficient arguments for performing further experimental and clinical studies.

Cancer cachexia is one of the most prevalent and devastating syndromes associated with advanced cancer. Its main clinical manifestation is profound anorexia. Progestational drugs have shown meaningful effects on appetite, food intake, and nutritional status in patients with advanced cancer and AIDS, and could be useful in managing anorexia. Corticosteroids also seem to produce increased appetite, but these effects are short-lived. Cyproheptadine, hydrazine sulfate, and cannabinoids also are being studied in the management of cancer-induced anorexia, but their role has not yet been clearly established. Future research should evaluate how the different drugs affect specific symptoms associated with cachexia.

Variables that the clinician can assess to determine the nutritional status of cancer patients include percent and rate of weight loss from usual body weight, current weight compared to calculated ideal body weight, and levels of appetite and food intake. Our studies show that two-thirds of patients with advanced cancer over the age of 65 have had some degree of weight loss, and that more than half are underweight, have loss of appetite, or complain of a decrease in food intake. Ongoing support and education, food supplementation, and attention to activity level may all contribute to preserve the patient's nutritional status and quality of life. Severe, persistent anorexia that does not respond to dietary counseling can be reversed with megestrol acetate. Enteral and parenteral nutrition have specific indications but should not be routinely used in anorectic patients.

This study represents the clinical and laboratory features of 135 tuberculous peritonitis cases in whom peritoneoscopic investigation was used routinely. Disease was more common in women than men (1.5:1) and was most frequently encountered in the third and fourth decades in life. The most common presenting symptoms were abdominal distension (96%), abdominal pain (82%), weight loss (80%), weakness (76%), loss of appetite (73%) and fever (69%). The most common physical findings were ascites (96%), fever (75%) and abdominal tenderness (43%). One hundred and twenty-nine cases (95.5%) showed exudative type tuberculous peritonitis with variable amounts of ascites and filmy adhesions. In six patients (4.5%) the disease was of the plastic (dry) type. Peritoneoscopic investigations of 139 patients suggested tuberculous peritonitis but four cases showed histologically proven malignancy (3%). Laparoscopic diagnoses of the remaining cases were confirmed by histology (97%). The laparoscopic appearance of scattered yellowish-white nodules, approximately 1-5 mm in size, on the peritoneal surfaces, and filmy adhesions were suggestive of tuberculous peritonitis. A non-fatal colon perforation occurred as a major complication. After antituberculous therapy patients were followed for at least 1 year. Peritoneoscopy with simultaneous biopsy is the ideal and most accurate diagnostic modality in the diagnosis of tuberculous peritonitis.

Age-related changes in clinical features of 182 patients diagnosed as having pulmonary tuberculosis from positive culture results of tubercle bacilli were extensively investigated. The percentage of cases detected using mass miniature radiophotography (MMR) was highest in the patients aged 30-39 years, and then decreased with increasing age. It was only 16-19% in those aged 60 years or older. Certain conditions, such as cardiovascular diseases, hypertension, diabetes mellitus, malignancy and other lung diseases, were common in the patients aged 60 years or older. Systemic symptoms, including weight loss and anorexia, and physical abnormalities, including fever and crackles, were common in these patients. Anemia tended to be predominant in the patients aged 60 years or older. The middle/lower lobes were involved more frequently in these patients, in whom the disease distribution was more than one lobe, or disseminated. Positive smear results and negative anergy were more frequently noted in the patients aged 60 years or older. The mortality from tuberculosis in these patients was 4% (7 cases). Although gastrointestinal disorder due to antitubercular drugs was more common in the patients aged 80 years or older, eosinophilia was less frequently observed. Today, improved conditions, better sanitation and the development of new chemotherapeutic agents have contributed to the decline of tuberculosis among the general population. But more efficient procedures that allow the early detection or diagnosis of pulmonary tuberculosis in the elderly should be achieved as soon as possible.

We examined how social, economic, location, health, and food need characteristics are related to elderly persons' not eating for 1 or more days. The following variables were positively related to not eating: ethnicity, location, receipt of Medicaid, living alone, health problems, mobility, age less than 80 years, cancer, nausea, difficulty swallowing, diarrhea, loss of appetite, and receipt of food from a food pantry. These results have implications for allocating meal program funds, screening clients, and monitoring whether clients eat regularly.

In this report we describe an experimental model of cachexia that fulfills the criteria of an early effect with a small tumor mass not related to the growth rate of the tumor, and progressive wasting of muscle and fat without a detectable loss of appetite. C-26.IVX is a cell line derived from murine colon-26 adenocarcinoma which retains the transplantability of the original tumor and induces true cachexia in syngeneic hosts. Evidence is presented to support a role for interleukin (IL-6) as a cachectic factor in the development of cancer cachexia in this model system. Thus, increasing levels of IL-6 in C-26.IVX-bearing mice correlate with the development of cachexia. If the primary tumors were resected, mice gained weight and the levels of IL-6 in the serum were reduced significantly. Moreover, monoclonal antibody to murine IL-6 (but not anti-tumor necrosis factor antibody) was able to significantly suppress the development of key parameters of cachexia in tumor bearing mice.

In a prospective open study, 61 consecutive patients with advanced cancer admitted to a Palliative Care Unit underwent survival estimation by two independent physicians after a complete medical exam performed during the first day of admission. An independent research nurse also assessed each patient during the first day of admission. The assessment included activity, pain, nausea, depression, anxiety, anorexia, dry mouth, dyspnea, dysphagia, weight loss, and cognitive status. After the assessment was completed, patients were followed until discharge or death. In 47 evaluable patients, logistic regression showed a significant correlation between survival and dysphagia, cognitive failure, and weight loss. Accordingly, an "indicator of poor prognosis" was considered to exist in any patient who demonstrated weight loss of 10 kg or more plus cognitive failure (Mini-Mental State Questionnaire less than 24) plus dysphagia to solids or liquids. This indicator had a similar level of sensitivity, specificity, and overall accuracy, and a higher level of significance as compared with the assessment by physician #1 and physician #2, respectively. Our data suggest that three simple determinations, which may be performed by a nurse, can predict survival more or less than 4 wk as well as the assessments of two skilled physicians. These results need to be confirmed in other trials with large numbers of patients. Perhaps confirmation of these results and identification of other prognostic factors will result in staging systems for survival estimation of terminally ill cancer patients.

Tumor necrosis factor (TNF), a pleiotropic cytokine, is produced by macrophages and other cells in a variety of infectious and noninfectious diseases. Ultimately, the net biological effects of TNF may be either beneficial or injurious to the host. For instance, during overwhelming bacterial infection, the acute overproduction of TNF causes septic shock syndrome characterized by hypotension, organ failure, and death. Antibodies against TNF prevent and reverse these sequelae in animal models of septic shock, and their use in humans is currently under investigation in clinical trials. In another instance, TNF has been implicated as an injurious mediator in the state of malnutrition that complicates the course of chronic infection and cancer. Termed cachexia, this chronic syndrome inevitably causes the afflicted host to succumb from weight loss, anorexia, and catabolism of protein and lipid. Experimental studies of animals exposed to TNF for protracted periods indicate that this cytokine is capable of causing cachexia, and the biochemical basis for these catabolic changes has been identified. More recent data indicate that the detrimental metabolic effects of TNF are not dependent upon its circulating levels in the bloodstream, but rather are dependent upon its actions locally in vital organs (e.g., brain). Thus, the metabolic basis for cachexia in infection may be largely dependent upon the amount of cytokine produced in metabolically important tissues. As a result, circulating TNF levels in cachectic patients may not accurately reflect the metabolic state of the host, and do not correlate to weight loss.(ABSTRACT TRUNCATED AT 250 WORDS)
