A multiparametric observation of cellular immune status by delayed hypersensitivity response to primary and recall antigens, absolute lymphocyte counts, T-cells counts, lymphocyte stimulation to PHA and serum immunoglobulin levels (IgG, IgM, IgA) was done in 60 patients of breast cancer and 40 age-matched normal controls. The findings were correlated with clinical stage, tumour size, lymphnode involvement, distant metastases, tumour differentiation, lymphoreticular response and tumour recurrence within one year of follow-up period. Delayed hypersensitivity response to DNCB, PPD and Candida was significantly impaired (P = less than .001) in breast cancer patients as compared to normal controls. DNCB and candida response showed a gradual decrease with increasing clinical stage and PPD response was impaired in the advanced stage (Stage III and IV). Patients with well-differentiated tumour were more anergic than those with poorly differentiated tumour. Delayed hypersensitivity response to both primary and recall antigen showed a good correlation with tumour recurrence. Patients who had early recurrence or progressive disease were more anergic to all the three antigens. Absolute lymphocyte counts, absolute T-cells and E-rosette were significantly reduced in breast cancer patients as compared to normal controls and further correlated with clinical stage. Absolute T-cells and E-rosettes were lower in patients with lymphnode involvement, and distant metastases as compared to those with localized tumour. Absence of lymphoreticular response was related with impaired T-cell population. Absolute T-cell counts and E-rosettes further correlated with prognosis of the patients being significantly impaired in patients with early recurrence or with progressive disease (P = less than .05).(ABSTRACT TRUNCATED AT 250 WORDS)

The cellular immune mechanisms of patients with adenocarcinoma of colon or rectum were evaluated by studying the lymphocyte response to PHA stimulation. Our results indicate that the serum of cancer patients causes a decreased blastic transformation and H(3) thymidine uptake of the lymphocytes of patients as well as of normal controls. A defect of the lymphocytes unrelated to serum factors was also present in some cancer patients. However, no relationship was found between the degree of transformation and the presence of metastases in the lymph nodes.

A new bleomycin derivative NK631 was administered in five cases of advanced recurrent oral carcinoma. The visible improvement of the tumor was noted in three cases, and in the cases of lower lip carcinoma the tumor completely disappeared, however, there was no effective change in cases of cervical metastases of the floor of the mouth and tongue carcinoma. The peripheral lymphocyte counts and serum proteins disclosed a characteristic decrease, serum proteins decreased in the albumin fraction and slightly increased in alpha 2-globlin fraction. Main side effects of NK 631 were skin exanthema, alopecia, anorexia, pyrexia, fatigue and bleeding from the tumor lesion. Regarding the lung function, the vital capacity did not change, but PaO and PaCO in blood gas analysis were together observed to slightly decrease, and it may be supposed that the influence of NK631 on the lung function cannot be neglected. T-cell ratio, lymphocyte blastoformation following PHA stimulation, PPD and DNCB skin tests, and phagocytosis test of peripheral leucocytes were studied. The immuno-suppressive effect of KK631 was the same or weak as bleomycin.

The effectiveness of Levamisole combined with Mitomycin-C, FT-207 and PS-K for treating gastric cancer was investigated in a prospective randomized controlled study. All patients had undergone gastrectomy during the years from August 1977 to November 1980. Five year survival rates revealed no difference between groups given or not given Levamisole. In those with positive lymph node metastases plus obvious serosal invasion, there was a significant elevation in the survival rate at four years after gastrectomy. The effectiveness of Levamisole was confirmed by postoperative changes in the PPD skin test, lymphocyte blastogenesis to PHA and serum inhibition index.

Single-step mutants were isolated from the murine metastatic MDAY-D2 cell line after selection in toxic concentrations of wheat-germ agglutinin. They were partially characterized by measuring their relative level of resistance to WGA, PHA, Con A, RIC, and LCA (Lec phenotype), and by comparing their karyotype and their ability to produce metastases upon transplantation into syngeneic DBA/2 mice. Based on their Lec phenotype, a total of 19 independent isolates were ranked into 10 distinct classes. Among them, two EMS-induced mutants were nontumorigenic (Lec II, Lec III), one nonmetastatic (Lec IV), and one spontaneous mutant (Lec I) failed to produce blood-borne metastases. Other spontaneous mutants belonging to Lec I, Lec II, and other classes were as metastatic as their parents. The Lec IV phenotype was found to segregate independently from metastatic potential in somatic hybrids. Metastatic ability was recovered in mutants expressing the Lec IV phenotype, after further selection for resistance to RIC. Our results strongly suggest that the loss or reduction of the invasive property of tumor cells is associated with only few Lecr1 phenotypes and, therefore, that a restricted number of cell surface glyconjugates are essential for this particular function.

Activities of T cell growth factor (TCGF) of conditioned media from PHA stimulated cultures of peripheral mononuclear cells (PHA-MNC-CM) were compared among patients with cancer, patients with non-malignant disease and normal persons. In nine out of 10 cases of cancer with metastasis (including extensive infiltration to surrounding tissues), the activities were much lower than normal persons, whereas in four out of five cases of cancer without metastasis, the activities were almost the same as those of normal persons. The low activities of PHA-MNC-CM from patients with metastatic cancer were not due to the older age of patients, nor did it seem to be attributed to the malnutritional state of patients. When we examined the activity using non-adherent MNC instead of the whole MNC, the activities in patients with metastatic cancer rose up to almost the normal levels. In normal persons the decline of the activities after 3 days of culture were not observed after the removal of adherent cells. Our data indicate that the adherent cells have a suppressive effect on TCGF production in both normal persons and cancer patients, but that the effect may be exaggerated in patients with metastatic cancer.

Immune response of regional lymph nodes was studied in 30 skin melanoma patients. T-lymphocyte count in metastatic lymph nodes was lower than in those without metastases. T-lymphocyte proliferation in response to PHA was inhibited 3-fold and the level of surface immunoglobulin-bearing B-lymphocytes was approximately 1.6 times lower in the involved node group. Cytological examination of the involved nodes detected a decrease in the counts of lymphocytes and reticular cells. This further confirms that metastatic involvement of lymph nodes is associated with a low immunologic activity, thus suggesting an unfavorable prognosis.

In 57 patients with Stage I cervical cancer and in 25 healthy women, a determination was made of leukocytosis, counts of lymphocytes and monocytes per 1 mm3 of blood, counts of T and B lymphocytes, and PHA-induced lymphocyte ability of in vitro blast transformation. Patients with cervical cancer, as compared with controls, exhibited a decrease in lymphocytosis and in the counts and percentages of T and B lymphocytes, as well as an increase of lymphocyte reactivity to PHA. An increase in the PHA-induced lymphocyte ability of in vitro blast transformation occurred in patients with a clinical picture characterized by the presence of a large tumor of the cervix or of metastases to the lymph nodes of the pelvis. In the group of patients in Stage I with a small cervix the mean indices of blast transformation did not differ from those observed for the healthy control group; on the other hand, in the group of patients with a large cervix and metastases to the lymph nodes of the pelvis, these indices exceeded on the average by about 88% those in the control group.

A survey of the lymphocyte status is reported for 25 patients given routine radiotherapy for carcinoma of the cervix or carcinoma of the breast and other tumours. After an initial lymphopenia there was a return to the initial value of the lymphocyte count by the end of a 12 month period of observation. The PHA index was also measured in these patients and this also showed a progressive rise during the 12 month period following a minimal change after radiotherapy. There was no significant difference between the lymphocyte status of patients given radiotherapy above or below the diaphragm nor between patients with or without knwon metastases at the end of the 12 month period. An additional sample of eight patients with carcinoma of the breast showed a rise in lymphocyte count after surgery before the usual fall after radiotherapy.

Clinical findings in 63 patients with malignant melanoma were compared with the results of PHA-induced lymphocyte transformation tests. The patients had been followed up for 1 to 60 months (average 16 months) and repeatedly tested at regular intervals. Reactivity of lymphocytes in stage I patients was not altered if compared with that of controls. The frequency of lowered values increased in more advanced stages. Only in stage II patients a significantly impaired PHA-lymphocyte transformation was demonstrated in comparison with controls. In stage I and II patients, there was no significant difference in lymphocyte transformation between those with the presence of tumor and those without clinically evident tumor. Prognostic value of PHA transformation tests as regards the appearance of distant metastases within two years after the first examination, could not be proven in patients at initial stages of melanoma.
