In a pilot study, the distribution of lymphocyte subpopulations in the peripheral blood and skin tests with recall antigens have been examined in 42 patients with gastrointestinal cancer before and during a perioperative parenteral hyperalimentation. Concerning the calories and the concentrations of amino acids and carbohydrates, two different solution regimens were applied. During parenteral nutrition with 2400 and 2200 kcal especially the absolute numbers of lymphocyte subpopulations increase reflecting the changes of total lymphocyte count. There was no marked difference between the 2 groups. Both solutions are qualified to balance the preoperative catabolic situation indicated by preoperative lymphopenia. This kind of parenteral nutrition did not influence the patient's cellular immunological status which was tested by 3 recall antigens. It must, however, be considered that the physical i.e. nutritional situation of the patients was not reduced to an extent where the immunological status was impaired. Our results suggest that in the perioperative period cancer patients should be supported by hypercaloric parenteral nutrition. On the other hand more sensitive immunological tests such as DNCB for skin testing and functional assays for in vitro tests are necessary to assess the effects of this kind of therapy.

The effect of intra-lymphatic administration of Lipiodol-l131 on the number of T and B lymphocytes, and on the in vivo response to common antigens and to DNCB, was investigated in uremic patients in the pre-transplant period. T lymphocytes have been detected by rosette formation with sheep erythrocytes (E) and B lymphocytes by rosette formation with erythrocytes sensitized with antibody and complement (EAC). After irradiation it was observed a lymphopenia due to a statistically significant decrease in the number of both T and B peripheral blood lymphocytes and a depletion of these cells in the irradiated lymph nodes. Their ability to give delayed hypersensitivity response to common antigens in vivo was lost after intralymphatic irradiation. Two patients were able to develop sensitization to DNCB and this reaction was supressed in one of them by irradiation. These effects of intralymphatic irradiation on the immune system favours further study of this method in clinical renal transplantation.

Eleven patients with stage-III cancer of the cervix were investigated before, during and after radio-therapy in regard to their state of humoral immunity on the basis of determinations of the serum IgG, IgM and IgA concentration, of hetero- and isoagglutinins, of tetanus antitoxin before and after vaccination with toxoid, of measles antibodies and of the percentage of lymphocyte membrane fluorescence. The cellular immunity of the same patients was investigated by determination of the percentage of spontaneously-rosetting lymphocytes, of skin-test reactivity with DNCB before and after sensitization, of skin-test reactivity with candida, trichophyton, varidase, OT and staphylo antigen. The function of polymorpho-nuclear leucocytes was investigated by means of the NVT test and St. aureus, E. coli and latex particles. All investigations were performed both before, and 3, 6, 9 and 12 weeks after the commencement of radiotherapy and the results were compared with those of an operated, non-irradiated group (stages I b and II a). Two types of noteworthy results were observed: 1. A decrease in immunological reactivity, probably in connection with cancer, since this reaction was observed both in irradiated and in non-irradiated cases, characterized by lowered or absent immune answer to tetanus toxoid, lymphopenia, decrease in sensitization to DNCB and less positive skin tests to old tuberculin and varidase. 2. An additional inhibition (although in one investigation stimulation of the immune answer was also seen), probably in connection with radiotherapy, characterized by an additional decrease in immune answer to tetanus toxoid, in skin sensitivity to DNCB sensitization and in tests with old tuberculin, and an augmented lymphopenia, as well as an increase in positive skin tests with varidase. No significant changes were observed with any other method.

Eighteen of 25 patients had squamous cell carcinoma in the supraglottic region. Anergy to skin test antigen (DNCB) and T-cell mitogen (PHA) was observed in 17 patients with laryngeal and laryngopharyngeal malignancies. Chemo-immunotherapy did not improve the skin reactivity to either agents. However, a rise in absolute T-cell counts was observed following combined therapy. Moreover, T-lymphopenia was detected in the patient group prior to therapy as compared to mean T-cell counts in normal control subjects.

Plasma zinc levels were measured in 95 elderly patients hospitalized in a long stay unit and in 100 healthy controls under 65 years of age. Plasma zinc concentrations were significantly lower in the elderly patients, as compared to the younger subjects (p 0.001). The correlations with serum prealbumin (p 0.05) and serum albumin (p 0.05) concentrations and the frequent association with protein-calorie malnutrition suggest that the low serum zinc levels mirror a low dietary zinc intake. Immunological tests in the elderly show moderate lymphopenia, high serum IgA and frequent depression of delayed cutaneous hypersensitivity to DNCB and PHA. We find a significant correlation between plasma zinc concentration and peripheral blood lymphocyte counts, but not the other immunological parameters. Linear discriminant analysis shows that the association of low plasma zinc values, low serum protein concentration and high serum IgG concentration implies poor prognosis.

The 60 patients of gastrointestinal cancer comprising this study were in the age range of 29--70 years with 39 males and 21 females. The primary sites of cancer were: gallbladder 19, colon 13, stomach 12, anorectum 8, and liver 8. The stage of tumor spread was localized in 32 and metastatic in 28 cases. Round cell infiltration scores were classified semiquantitatively from O-V. Cellular immunity as expressed by the blood lymphocyte count and DNCB reactivity was also studied. Round cell infiltration was dense in the localized group (P less than 0.0005). The mean lymphocyte counts in all the primary sites of gastrointestinal cancer were significantly higher in the localized group as compared to metastatic group. The DNCB reactivity showed anergy in six cases and poor response in the remaining 22 cases of metastatic group. There was a statistically significant correlation between lymphoreticular infiltration, peripheral blood lymphocyte count, and the DNCB reactivity. Diminished round cell infiltration, lymphopenia, and depressed DNCB response indicate an advanced stage of gastrointestinal cancer.
