In vitro assays of immunocompetence were done in 60 patients with differing extents of tumor load and various histologic types of lung cancer and were compared to values obtained for 60 normal controls. Profound alterations in monoclonal antibody-defined T-lymphocytes and circulating B-cells were seen. All patients showed impaired blastogenic response to the mitogens used with the exception of a normal response to pokeweed mitogen (PWM) in patients with localized disease. Increase levels of serum IgG were seen in patients with localized disease whereas high levels of IgA was seen in patients with more advanced disease. Distant metastases were associated with low IgM levels. All patients studied regardless of stage and histologic type had elevated levels of circulating immunocomplexes. These findings indicate gross immunologic abnormalities in these patients.

In the present paper is studied the concentration in peripheral blood of immunoglobulins IgG, IgA, IgM and factors C3 and C4 of the complement system in a group of 120 patients with colorectal cancer operated on with radical intention. Preoperative values are compared to postoperative results and the values obtained on diagnosis of tumoral recurrence with the object of describing possible immunologic alterations existent in the patient with colorectal carcinoma. It is concluded that there are no significant relations between the biochemical parameters studied and age, sex, tumoral localization and Duke's clinical stages. Patients with pre and postoperative IgA values above normal present a poor prognosis, with an associated recurrence of 60% (p = 0.001) and 80% (p = 0.000), respectively; postoperative C3 levels above normal also represent a factor of poor prognosis, recurrence appearing in 80% (p = 0.001) and metastases in 85% (p = 0.000).

Serological follow-up studies for up to 4 years on the levels of IgG antibody to EBV-determined nuclear antigen (EBNA) were carried out on 36 patients with nasopharyngeal carcinoma (NPC). The serum levels of IgA antibody specific to EBV capsid antigen (VCA) were also measured in some of the patients. The titers of EBNA antibody were measured by enzyme-linked immunosorbent assay (ELISA) and those of IgA antibody to VCA were measured by the indirect immunofluorescence method. The EBNA antibody titers in most sera from the patients before radiation therapy were found to be at least 4 times the mean values in the sera of healthy control adults. Within 2 to 8 months after completion of therapy by 4-MV liniac X-ray irradiation with total doses of 60 to 80 Gy, the titers of EBNA antibody in the sera of 6 patients had returned to normal levels, and low levels of EBNA antibody were maintained for a long time after therapy. These serological data were associated with a good clinical prognosis without recurrence or metastases. But in 6 patients, the patterns of change in the EBNA antibody levels were different: the levels remained high after therapy or first decreased to the normal level and then rose to at least 4 times this level. These 6 patients showed recurrence or metastases. The patterns of change in the EBNA antibody levels were well correlated with those of change in the levels of IgA antibody specific to VCA.(ABSTRACT TRUNCATED AT 250 WORDS)

IgA antibodies to Epstein-Barr virus capsid antigen (IgA anti-VCA) can be detected in sera of patients with certain types of nasopharyngeal carcinoma (NPC). IgA anti-VCA titres were determined by the indirect immunofluorescence technique. 17 control patients with benign diseases or carcinomas of the head and neck other than NPC had negative IgA anti-VCA titres less than or equal to 1:16. NPC was diagnosed histologically according to the Cologne modification of the WHO classification. Among 16 cases of untreated or recurrent NPC, a rare disease in Europe, seen over the past three years, those with undifferentiated carcinomas with and without lymphoid stroma and the non-keratinizing carcinomas with lymphoid stroma were IgA anti-VCA positive (1:32 to 1:512), whereas patients with squamous cell carcinomas were negative. In four cases the primary tumour had not been diagnosed by other ENT doctors in spite of known regional or distant metastases consisting of undifferentiated carcinomas with or without lymphoid stroma. IgA anti-VCA antibodies in the sera of these patients indicated the probable site of the primary tumour. NPC was verified by biopsy in all these cases. In 2 serologically negative patients the original diagnosis of undifferentiated NPC with lymphoid stroma had to be revised to malignant Non-Hodgkin lymphoma. In the follow-up of 6 NPC patients the trend of changes in IgA anti-VCA titres correlated with the course of the disease, but the minute tumour-related changes could be detected only when at least two previous sera of the same patient were included in every test.(ABSTRACT TRUNCATED AT 250 WORDS)

In an attempt to identify biologic markers that might predict prognosis in breast cancer patients, the presence or absence of seven tumor-associated antigens in 54 infiltrating breast carcinomas was correlated with tumor recurrence rates (minimum five-year follow-up), axillary lymph node metastases and tumor volume. Immunohistochemical kappa-casein was present in 30 (56%) tumors, alpha-lactalbumin in 39 (72%) tumors, secretory component of IgA in 26 (48%) tumors, carcinoembryonic antigen in 34 (63%) tumors, pregnancy-specific beta-1-glycoprotein in 7 (13%) tumors, beta subunit of human chorionic gonadotrophin in 1 (2%) tumor and human placental lactogen in 0 (0%) tumors. There was no significant correlation between the presence or absence in tumor of any of the antigens, and prognosis as assessed either by 5-year recurrence rates (P greater than 0.18) or by the presence of axillary lymph node metastases (P greater than 0.20). No significant difference was noted in mean tumor volume (cm3) +/- SEM, between tumors with or without antigen immunoreactivity (P greater than 0.05).

We report on 123 patients with nasopharyngeal carcinoma whose immune status was measured at the time of diagnosis, the day radiotherapy was completed, and then 2-3 months and 6-8 months after completion of radiotherapy. Immunological tests performed included the lymphocyte transformation test, the erythrocyte-rosette formation test (ERFT), the 29 degrees C erythrocyte-rosette formation test (29 degrees C ERFT), lymphocyte counts (lymphocytes/mm3 and percentage of lymphocytes), levels of serum immunoglobulins (IgG, IgA, IgM), complement (C3) and circulating immune complexes (CIC), the antinuclear antibody test and a skin test using phytohaemagglutinin (PHA). There were statistically significant differences in all tests (except C3) between patients and normal controls. Marked differences were seen in the lymphocyte count, ERFT, and 29 degrees C ERFT after radiotherapy (p less than 0.01). The diameters of induration of the PHA skin tests were less than those before radiotherapy (p less than 0.01). There were higher incidences of recurrence and metastases in the patients with high levels of CIC and low numbers of lymphocytes in the peripheral blood after radiotherapy. Cellular immunity remained at a low level 8 months after radiotherapy.

Alveolar lavage is a simple technique giving access to the inner lung. The object of this study is to assess the place of alveolar lavage in pulmonary tumours in man. The systemic changes in the immune system are not touched upon, nor the search for tumour cells. The supernatant has revealed greater than normal levels of carcino-embryonic antigen in primary tumours and metastases. The immunoglobulins (IgE, IgA) are increased also. The ready collection of the alveolar macrophages (MA) around the tumour permits a study of their functional capacity: chemotaxis, phagocytosis, cytotoxicity. The chemotaxis of MA breaks down around a primary cancer even though it is not changed in pulmonary metastases. The data in the literature concerning the capacity for phagocytosis and of anti-tumour cytotoxicity are still fragmentary. Increasing the tumoricidal properties of MA is a prospect for future. Alveolar lavage is an additional diagnostic method. It allows for a progressive scrutiny of the local immunological response in broncho-pulmonary tumours.

Two hundred and eighty-six patients presenting with metastatic adenocarcinoma or undifferentiated carcinoma whose primary site was not identified by clinical history, physical examination and chest radiograph have been studied. Median survival from presentation was 22 weeks. Factors independently predicting improved survival were lymph node presentations, good performance status and body weight loss of less than 10 per cent. In 88 (31 per cent) patients the primary tumour site was subsequently identified, in 58 (20 per cent) during life. Lung cancer was the most frequently identified primary tumour, and in only 32 (11 per cent) of the patients was a 'treatable' primary tumour (i.e. germ cell, breast, ovarian, prostate, thyroid cancer or lymphoma) identified. Among the treatable primary tumours were those in eight out of 16 female patients presenting with axillary metastases who were subsequently shown to have primary breast cancer and four of 13 females presenting with ascites who were found to have primary ovarian cancer. Prostatic cancer was confirmed in five out of 13 men with raised serum acid phosphatase. Of 22 patients with elevated serum alphafoetoprotein (AFP) or beta-human chorionic gonadotrophin levels (beta HCG) 18 had some features of the 'atypical teratoma syndrome'. Of the total of 32 patients with treatable tumour types, 29 (90 per cent) were identified during life. Median survival for patients with treatable tumour types identified during life was 104 weeks, compared with 22 weeks for the group as a whole. Retrospective immunocytochemical staining of the original biopsy showed that prostatic specific antigen and antibodies to beta HCG and AFP were diagnostically useful, but a series of organ site non-specific markers of histogenesis or cellular differentiation (carcinoembryonic antigen, secretory component for IgA, peanut lectin binding, epithelial membrane antigen and keratin) showed no significant correlations with identified primary sites, responsiveness to empirical chemotherapy or survival. Metastatic undifferentiated carcinoma or adenocarcinoma from an unknown primary site represents 6.5 per cent of all referrals to the medical oncology unit, Royal Prince Alfred Hospital, Sydney. We offer guidelines for the rapid identification of the limited number of primary sites for which effective and specific forms of systemic treatment are available.

The levels of plasma secretory IgA were measured in patients with gastric cancer and found to be slightly higher (9.6 +/- 6.2 micrograms/ml) than those in healthy controls (7.0 +/- 2.6 micrograms/ml, 0.05 less than P less than 0.1). Secretory IgA levels in those with hepatic metastases (19.7 +/- 12.2 micrograms/ml) were significantly higher than those in patients without hepatic metastases (P less than 0.001). In the latter, there was no significant relationship between plasma secretory IgA levels and the deepest layer of cancerous invasion or lymph node metastases. The secretory IgA levels in cases of well differentiated tubular adenocarcinoma were significantly higher than those with poorly differentiated adenocarcinoma (P less than 0.05). Although there is small diagnostic value in the detection of gastric cancer by measuring the levels of secretory IgA, high levels of secretory IgA in gastric cancer patients may be indicative of the presence of hepatic metastases.

The immunohistochemical determination of immunoglobulins IgA, IgG and IgM in axillary lymph nodes from 50 unselected breast ductal carcinomas disclosed that lymph nodes with IgG-positive lymphoid follicles and/or metastasized lymph nodes with IgM-positive lymphoid cells are statistically related to breast tumors with a high histologic grade and more than 3 lymph node metastases.
