The author used the method of abdominal phonography to study the motor activity of the gastrointestinal tract after resection of the stomach for carcinoma and also to determine the degree of the effect of different stages of the operation and of its volume upon the motor function in 88 patients. Diagnostic laparotomy was carried out in 41 patients. The phonography findings showed postoperative depression of gastrointestinal motor function in the most of cases within the first days after operation.

During the last 4 years, 225 patients have been referred to the Danish Cholinesterase Research Unit following an episode of prolonged apnoea after suxamethonium. Fourteen patients (6.2%) were found to have a low serum cholinesterase activity due to an acquired deficiency (for instance, liver disease, chronic debilitating disease or carcinoma). One hundred and forty-eight patients (65.8%) had an inherited abnormal serum cholinesterase, and 105 of these patients (46.7%) were homozygous for the atypical enzyme (E1 Ea1). The mean period of apnoea in this latter group was 92 min (range: 25--240). Seventeen patients (7.6%) were heterozygous for the normal and the atypical enzyme (Eu1 Ea1), with a mean apnoea period of 25 min (range: 7--60 min). Twelve patients were found to be heterozygous for the atypical and the silent gene (E(a)1 E(s)1). The mean period of apnoea was 126 min (range: 45--210 min). Fourteen patients had other rare genotypes. The longest mean period of apnoea (170 min, range: 70--330) was found in patients homozygous for the silent gene (Es1 Es1). The silent gene and the fluoride-resistant gene were found in 8.9% and 2.7% of the patients, respectively. In 63 patients (28.1%) both the type and quantity of serum cholinesterase were normal. In 34 of these patients (15.2%), the prolonged apnoea was due to other causes; for example, suxamethonium overdose, hyperventilation and central as well as peripheral respiratory depression. However, in the other 29 patients (12.9%), the reason for the prolonged apnoea could not be established. The possibility therefore exists that these cases represent unknown genotypes.

To assess the effects of radiotherapy on immune status, a wide range of assessments have been performed on patients with localized carcinoma of the cervix uteri undergoing and initially responding clinically to radical pelvic radiotherapy. Neutrophil function was essentially unchanged by treatment. Absolute neutrophil and lymphocyte counts fell after treatment and remained depressed 3 and 12 months following treatment. The proportions of T and B cells dropped with treatment but recovered to near-presentation levels during the follow-up period even though absolute counts remained depressed. In vitro tests of cellular immunity were depressed by treatment and remained so 3 and 12 months following treatment whereas skin test responses remained normal throughout the assessments. Inhibitory plasma effects were observed in phytohaemagglutinin lymphocyte transformation studies on 4 untreated patients; at follow-up these effects were not evident. A variable response in immune indices has therefore been observed in patients in remission after treatment of localized carcinoma cervix stressing the importance of assessing several aspects of immune function and implying that persistent depression of certain indices does not adversely affect the host tumor response. In two patients relapsing after apparently good initial response all aspects of immunological assessment (except serum immunoglobulin levels and neutrophil function) deteriorated.

The toxicity of Melphalan to murine bone marrow was assessed by automated Coulter counts of femoral marrow nucleated cells. A significant dose-response slope (p less than 0.001) was shown and also a significant variation along the 24 h scale. With food available ad libitum and light from 06.00 to 18.00 hours, the minimum marrow depression occurred around 16.00 hours. Extrapolating these findings to human chemotherapy it would appear that prescription of the drug during the early part of the activity span (usually breakfast) will minimize marrow depression. This differs from a human study in which Melphalan was given at 'bedtime' as an adjuvant to mastectomy in breast carcinoma and in which there was leucopenia at some stage of treatment in all 103 patients. It is recommended that in future cancer therapy protocols test for circadian variability of white cell depression by varying treatment times systematically along the 24 h scale.

Polymyalgia rheumatica developed in a 71-year-old patient within 2 years of the onset of acute sarcoidosis with biopsy-verified involvement of the thyroid, and concomitant autoimmune thyroiditis with hyperthyroid symptoms. Three years after the onset of muscle symptoms a non-metastasizing breast carcinoma was discovered and treated surgically. Neither the long interval between the onset of polymyalgia rheumatica and the discovery of the breast tumour, nor the good response of muscle symptoms to a one-year maintenance treatment with corticosteroids, was consistent with a paraneoplastic mechanism of the polymyalgia rheumatica syndrome. It was therefore hypothesized that the various disorders suffered by this patient might be related to a partly age-dependent depression of T-lymphocyte function, leading to an altered immunological reactivity to which the various clinical manifestations could be attributed. Such a hypothesis is supported by recent reports showing that in old people and in ageing experimental animals, a decrease in T-lymphocyte function and in the number of circulating T-cells occurs concomitantly with an increase in the incidence of a variety of neoplasms and autoimmune disorders.

Administration of serum presumed to contain tumor-specific antibodies supported the rejection in immunized mice of syngeneic fibrosarcoma implants which receded after an initial period of s.c. growth. Passive transfer of immune serum to unsensitized mice, sublethally radiated and injected with normal lymph node cells, protected the recipients against i.v. but not against s.c. implantation of syngeneic mammary carcinoma cells. Injection of immune serum assisted the recovery of mice in a state of tumor-induced specific immune depression induced by a large. s.c. mammary carcinoma implant and maintained after surgical cure by injections of serum presumed to contain soluble tumor antigen.

Fifty patients with testicular carcinoma, 45 with prostatic neoplasm, 84 with bladder carcinoma, and 13 with benign bladder papilloma were evaluated for skin reactivity to DNCB and other intradermal antigens. Correlation between pathologic staging and skin-test reactivity was sought. Reaction to DNCB among patients with testis tumors was more significantly depressed by chemotherapy than by the extent of retroperitoneal or distant metastatic disease indicating that skin testing as a means of following the course of disease or of predicting survival may be limited by alterations caused by chemotherapy. DNCB reactivity did not correlate with the prognosis for the different stages of disease, but follow-up studies of individual patient survival are needed for substantiation. Depression of DNCB reactivity exists among patients with prostatic carcinoma whether the disease is localized or widely metastatic. Only lengthy follow-up will determine if there is any correlation of reactivity with survival in individual patients. DNCB reactivity among patients with bladder tumors shows progressive reduction with increasing stage disease and lends support to the evidence suggesting immune deficiency in patients with bladder neoplasm.

Carcinoma of the thyroid gland is not common. The majority of lesions in this series were differentiated in type. The treatment of choice is almost total thyroidectomy supplemented by I131 in some cases. L-thyroxine was prescribed routinely for all patients postoperatively for replacement and depression treatment. The immediate postoperative mortality was about 1% and prognosis is relatively good. Undifferentiated thyroid carcinomas are fast growing and very lethal and unfortunately no method of treatment is effective. Only four patients in this group survived more than a year.

Active human serum manifests a tumoricide effect against cells of the Ehrlich ascites tumor. Sera of patients with Ca ventriculi show a higher effect than those of patients with a chronic streptococcal disorder, in comparison with intact subjects. This tumorcide effect is depressed by Varidase, the degree of depression being greatest in the group of patients with streptococcal infection, smaller in healthy subjects and least in carcinoma patients. The investigated sera contained antibodies against Varidase, but not against streptokinase. The anti-Varidase antibodies are found also in sera of the new-born children. The decline of the tumoricide activity of Varidase-treated sera is related to the quantity of anti-Varidase antibodies determined by complement fixing reaction in non-treated sera.

Leucocytes from 22 out of 26 patients with mammary carcinoma were significantly cytotoxic in vitro for cells cultured from mammary tumours though only two out of 17 of these preparations were cytotoxic for cells cultured from tumours arising at other sites. In the immediate postoperative period reactivity of patients' leucocytes with mammary tumour cells was undetectable but returned within one week of surgery. Leucocyte cytotoxicity may therefore offer a model in which the mechanism of postoperative depression of immunological competence may be investigated.
