Abstract
Arginase 1 (ARG1) inhibits T-cell proliferation by degrading extracellular arginine, which results in decreased responsiveness of T cells to CD3/TCR stimulation. In humans, ARG1 is stored in inactive form within granules of polymorphonuclear neutrophils (PMNs) and gets activated on release. We studied the role of PMNs-related ARG1 activity in nonsmall cell lung cancer (NSLC), in which tumor-infiltrating lymphocytes showed reduced proliferation in response to CD3/TCR triggering. Patients with NSCLC had increased ARG1 plasma levels as compared to healthy controls. Furthermore, immunohistochemistry showed that tumor-infiltrating PMNs display reduced intracellular ARG1, in comparison to intravascular or peritumoral PMNs, suggesting a role of tumor microenvironment in ARG1 release. Indeed, supernatants of NSCLC cell lines induced exocytosis of ARG1 from PMNs. All (4/4) NSCLC cell lines and all (7/7) CD14- cell samples from NSCLC expressed interleukin (IL)-8 mRNA, whereas TNFalpha mRNA was expressed by 1 cell line and by 2 tumor specimens. Furthermore, all NSCLC cell lines secreted immunoreactive IL-8, albeit at different levels. IL-8 was as effective as TNFalpha in triggering ARG1 release and the 2 cytokines acted synergistically. Secreted ARG1 was biologically active and catabolized extracellular arginine. The supernatant of IL-8 gene-silenced NSCLC cells did not mediate ARG1 release by PMNs. Altogether these findings demonstrate a role of IL-8 in ARG1 exocytosis by PMNs and indicate that, due at least in part to IL-8 secreted by NSCLC cells, PMNs infiltrating NSCLC release ARG1. This phenomenon could contribute to local immune suppression.

Abstract
S-100 protein expression is present in various malignant tissues, yet its prognostic relevance is debatable. The aim was to assess in non-small cell lung cancer (NSCLC) patients' prognostic value of S-100 protein considered alone or in relation with other variables. Tumour samples taken from 86 NSCLC patients during resection were assayed for S-100 protein expression with the use of polyclonal DAKO ZO311 antibody. S-100 expression was found in 32 cases (37%). Positive staining was not correlated with clinical characteristics including age, sex, pathology type of tumour, stage and cigarette smoking. There was a tendency for simultaneous expression of S-100 and P53 protein (p=0.06). A median survival rate for the entire group was 2.3 years (95% CI, 0.9-3.6 years). The median and 5-year survival of patients with positive staining for S-100 protein was 1.5 years and 25%, respectively, compared with 3.0 years and 35%, respectively, in the S-100 negative group (p=0.17). In the final model of a multivariate analysis, S-100 protein expression in tumour cells was associated with significantly decreased survival (p=0.005). S-100 protein expression in tumour cells seems to be an independent predictor of poor prognosis in NSCLC patients.

Abstract
In human prostate cancer, Arginase 2 (ARG2) and nitric oxide synthase (NOS) are concomitantly expressed by tumor cells, and induce tumor immune escape via peroxynitrite-dependent Tyrosine nitrosylation. Since there were no data regarding this immune suppressive mechanism in other tumor types, and an evaluation of its clinical relevance in human tumors had still to be provided, we have investigated presence and clinical relevance of ARG2 and NOS expression in lung cancer. No evidence of NOS expression was found, no significant NOS enzymatic activity was detected. Instead, ARG2 protein was expressed by tumor cells. In a cohort of 120 patients, the amount of ARG2-positive tumor cells was significantly higher in small cell lung cancers (SCLC) than in non-small cell lung cancers (NSCLC). Large cell undifferentiated carcinomas had twice ARG2 than the other NSCLC subtypes. ARG2 expression was increased in Grade 3 tumors, as compared to Grades 1 and 2. However, no relationship was found with tumor size and stage, and with patient survival. Indeed, the enzyme was active, since the Arginine catabolite Ornithine was produced, but Arginine depletion was not attained. In addition, nitrotyrosine was not found in tumor tissue. Accordingly, when tumor cells isolated from lung cancer were incubated with activated autologous T cells, no inhibition of proliferation was detected. Our results indicate that ARG2 is expressed in lung cancer, but it does not induce tumor immune escape and does not affect disease progression, most probably due to the lack of concomitant NOS expression.

Abstract
BACKGROUND A 17-cytokine gene expression signature in noncancerous hepatic tissue from patients with metastatic hepatocellular carcinoma (HCC) was recently found to predict HCC metastasis and recurrence. We examined whether the cytokine gene expression profile of noncancerous lung tissue could predict the metastatic capability of adjacent lung adenocarcinoma. METHODS We analyzed a 15-cytokine gene expression profile in noncancerous lung tissue and corresponding lung tumor tissue from 80 US lung adenocarcinoma patients using real-time quantitative reverse transcription-polymerase chain reaction. We then used unsupervised hierarchical clustering and Prediction Analysis of Microarray classification to test the prognostic ability of the 15-cytokine gene profile in the US patients and in an independent validation set comprising 50 Japanese patients with stage I disease. Survival was analyzed by the Kaplan-Meier method using the log-rank test, and univariate and multivariable Cox proportional hazards modeling were used to analyze the association of clinical variables with patient survival. All statistical tests were two-sided. RESULTS A 15-cytokine gene signature in noncancerous lung tissue primarily reflected the lymph node status of 80 lung adenocarcinoma patients, whereas the gene signature of the corresponding lung tumor tissue was associated with prognosis independent of lymph node status. Cytokine Lung Adenocarcinoma Survival Signature of 11 genes (CLASS-11), a refined 11-gene signature, accurately classified patients, including those with stage I disease, according to risk of death from adenocarcinoma. CLASS-11 prognostic classification was statistically significantly associated with survival and was an independent prognostic factor for stage I patients (hazard ratio for death in the high-risk CLASS-11 group compared with the low-risk CLASS-11 reference group = 7.46, 95% confidence interval = 2.14 to 26.05; P = .002). CLASS-11 also classified patients in the validation set according to risk of recurrence. CONCLUSION CLASS-11, which consists of genes for pro- and anti-inflammatory cytokines, identifies stage I lung adenocarcinoma patients who have a poor prognosis.

Abstract
BACKGROUND Neoangiogenesis and the immune response are important mechanisms in metastasis development. AIM to evaluate lymph node reactivity and microvessel density in neck metastasis of occult primary squamous cell carcinoma considering their histological and clinical variables. STUDY DESIGN retrospesctive case-series. METHOD 19 patients with neck metastasis of occult primary squamous cell carcinoma who underwent neck dissection between 1983 and 2000 were selected. The lymph nodes were reevaluated on the type of reactivity in both the cortical and paracortical areas, and the metastasis were assessed as to grade, desmoplasia, necrosis and microvessel density (CD34). The relationship between histological and clinical variables was evaluated. RESULTS the median microvessel density was 91 vessels/mm2, varying from 28 to 145. Paracortical hyperplasia was more common in patients below 55 years of age (90%x44%, p=0.05), but there was no relationship between reactivity patterns and microvessel density with prognosis. The disease-free survival was 52% in 3 years, being similar in both groups, with higher or lower microvessel densities. CONCLUSION microvessel density in neck metastasis of occult primary squamous cell carcinoma had a great individual variability. It wasnt possible to establish the relationship between microvessel density and the clinical or histological variables studied.

Abstract
Adoptive immunotherapy--the isolation of antigen-specific cells, their ex vivo expansion and activation, and subsequent autologous administration--is a promising approach to inducing antitumour immune responses. The molecular identification of tumour antigens and the ability to monitor the persistence and transport of transferred cells has provided new insights into the mechanisms of tumour immunotherapy. Recent studies have shown the effectiveness of cell-transfer therapies for the treatment of patients with selected metastatic cancers. These studies provide a blueprint for the wider application of adoptive-cell-transfer therapy, and emphasize the requirement for in vivo persistence of the cells for therapeutic efficacy.

Abstract
BACKGROUND Numerous studies have investigated locoregional immune responses and long term survival in patients with various types of cancer; few have focused on patients with lung carcinoma. The current study was designed to assess the prognostic value of immunomorphologic changes in locoregional lymph nodes and lymphocytic infiltration of primary tumor (LI) in patients who undergo resection for bronchogenic carcinoma. METHODS In a retrospective analysis, immune responses in locoregional lymph nodes and at primary tumor sites were studied histologically in 172 selected patients. Lymph node morphology was studied according to the system of Cottier et al. Sinus histiocytosis and paracortical lymphoid cell hyperplasia were considered to be cellular immune responses, and follicular hyperplasia of the cortical area was considered to be a humoral reaction. LI was classified with Black's method. The survival rate was estimated by using the Kaplan-Meier product-limit method. The log rank test and the Cox proportional-hazards model were used to determine statistical significance in univariate and multivariate survival analyses. RESULTS Among the 172 patients, 35.5% had no evident response in regional lymph nodes, 19.8% had a marked cellular response, 11% had a marked humoral response, and 33.7% had a mixed cellular and humoral response. LI was intense in 36.6% of patients and was absent or scarcely evident in 63.4%. A lymph node cellular response and marked LI improved long term survival rates even in patients with regional lymph node metastases. Multivariate analysis identified two independent variables that had high prognostic value: lymph node immunoreactivity and LI. CONCLUSIONS Lymph node immunoreactivity and LI significantly influence long term survival after curative surgery for patients with carcinoma of the lung and may be useful in stratifying patients for prospective trials of adjuvant treatment, including immunotherapy.

Abstract
BACKGROUND T helper type 1 cells (Th1), Th2, T cytotoxic type 1 cells (Tc1), and Tc2 play important immunoregulatory roles. Some recent studies have demonstrated that an elevated level of type 2 cytokines, such as interleukin-10, contributes to the ability of cancer cells to escape immunosurveillance. However, the impacts of Th1, Th2, Tc1, and Tc2 on tumor immunity are unclear. METHODS The authors evaluated the ratio of Th1 to Th2 and that of Tc1 to Tc2 among peripheral blood lymphocytes (PBL), regional lymph node lymphocytes (RLNL), and tumor-infiltrating lymphocytes (TIL) in 46 nonsmall cell lung carcinoma patients who had just undergone surgery; the evaluation involved detecting the intracellular interferon-gamma and interleukin-4 production with 3-color flow cytometry. They also evaluated the same ratios in the peripheral blood lymphocytes of 29 lung carcinoma patients with or without recurrence after surgery, and in the peripheral blood of normal volunteers. RESULTS The Th1-to-Th2 and Tc1-to-Tc2 ratios were significantly elevated in the tumor tissues. These ratios in the TIL were significantly elevated in the groups of patients with squamous cell carcinoma and a history of smoking. The Th1-to-Th2 and Tc1-to-Tc2 ratios were significantly depressed in the PBL of the patients with tumor recurrences. CONCLUSIONS A favorable Th1- and Tc1-dominant pathway is induced in the tumor tissues of operable patients, but their pathway can be expected to shift from Th1 or Tc1 to Th2 or Tc2 with the progression of cancer.

Abstract
BACKGROUND To evaluate the immunologic activity of regional lymph nodes, the phenotype of lymphocytes and the functional expression of cell adhesion molecules (CAMs) on lymph node lymphocytes (LNL-: uninvolved, LNL+: involved) were investigated in patients with gastrointestinal carcinoma. METHODS The lymphocyte subpopulation and the expression of CD11a, CD44, and CD29 on CD4+ and CD8+ cells in peripheral blood lymphocytes (PBL), LNL- and LNL+ derived from 37 patients with gastrointestinal carcinoma were studied. In addition, the adherence of CD8+ cells to ICAM-1 which reflects the adhesive function of CD11a, was examined, and changes in this adherence were studied by experimental coculture with cancer cells (DLD-1). RESULTS Although there were no differences in the overall proportion of T cells between the groups, CD8+ cells and CD16+ cells were considerably diminished in LNL+. The expression of CD11a and CD29 on CD4+ and CD8+ cells was significantly lower in LNL than in PBL, whereas the expression of CD44 showed no significant differences. The expression levels of these CAMs were almost the same in LNL- and LNL+. Only CD11a expression on CD8+ cells in LNL+ was significantly lower than that in LNL- (P < 0.005). The adherence of CD8+ cells in LNL+ to ICAM-1 was lower than that in PBL and LNL-, and was extremely enhanced by experimental coculture with cancer cells (DLD-1). CONCLUSIONS These data indicate that the functional expression of CD11a (LFA-1) on CD8+ T cells is suppressed in cancer-involved regional lymph nodes in patients with gastrointestinal carcinoma.

Abstract
Using two- and three-color flow cytometry, we investigated the surface makers of regional lymph node lymphocytes (RLNL) in 54 patients with primary lung cancer in order to determine whether or not RLNL are in an activation state when compared with the corresponding peripheral blood lymphocytes (PBL) for the purpose of clarifying the characteristics of RLNL. RLNL showed a cell composition that was different from the corresponding PBL with a high proportion of CD3+ cells, CD4+ cells and CD20+ (B) cells as well as a low proportion of CD8+ cells and CD16+ (NK) cells. RLNL also contained a significantly higher proportion of CD45RO+ T cells and a lower proportion of CD45RA+ T cells in comparison to the corresponding PBL. Furthermore, we explored the activation-related molecules such as the interleukin-2 receptor (IL-2R) alpha chain, the IL-2R beta chain, HLA-DR and leukocyte function-associated antigen 1 (LFA-1) on CD4+ and CD8+ cells. The data showed that the expression of CD45RO, the IL-2R alpha chain, HLA-DR on CD4+ cells, and those of CD45RO and HLA-DR on CD8+ cells were significantly higher in RLNL than in PBL. On the other hand, PBL showed a higher expression of the IL-2R beta chain and LFA-1 only on CD8+ cells, which are thought to include CD8+ NK cells. When these activation related molecules were analyzed on CD45RO+ T cells, which are thought to be memory T cells, then the expression of the IL-2R alpha chain, HLA-DR on CD4+CD45RO+ cells and HLA-DR on CD8+CD45RO+ cells were significantly higher in RLNL than in PBL. Lastly, we analyzed the surface molecules according to such clinical factors as metastasis to the lymph nodes and the stage of lung cancer. Interestingly, RLNL with lymph node metastasis showed an increase in the percentage of CD20+ cells and a decrease in the percentage of CD4+ cells in comparison to those with benign lung disease, while these differences were not observed in PBL. The expression of ++CD45RO and LFA-1 on CD4+ and LFA-1 on CD8+ cells on RLNL in stage I + II is significantly higher in comparison with benign lung disease. Furthermore, RLNL in stage III + IV revealed the reduced expression of CD45RO, HLA-DR and LFA-1 on both CD4+ and CD8+ cells compared with those in stage I + II. These results thus demonstrated that RLNL were in a more activated state, particularly in stages I + II, than PBL. Whether these activation states in RLNL are directed against autologous tumor cells or not can hopefully be elucidated after the completion of further ongoing studies.

Abstract
Out of 642 primary lung cancer patients who underwent surgery between 1986 and 1992, 82 cases who underwent curative resection were enrolled for a randomized prospective controlled study of postsurgical adjuvant immunotherapy using Interleukin 2 (IL-2) and lymphokine activated killer (LAK) cells. From 1986 to 1989 (the initial period), Stage IIIA patients were divided into three groups: group A (chemo-immunotherapy) received IL-2, LAK cell adoptive immunotherapy after two courses of anticancer (CDDP, VDS, MMC) chemotherapy, group B (control) received no adjuvant therapy, and group C (chemotherapy) received the same anticancer chemotherapy as group A. In the latter (1990-1992) period, group C was discontinued because of poor results and Stage II and IIIA cases were randomly assigned to group A or B. The 5- and 7-year survival rates of group A (33 cases) and B (36 cases) were 58.2% and 31.5%, respectively in Stage II and IIIA cases. The prognosis of group A was significantly better than that of group B (P = 0.0038 by the Cox-Mantel (C-M) test and 0.0033 by the generalized Wilcoxon (G-W) test). The 5- and 8-year survival rates of each group for Stage IIIA cases were 53.4% (group A, 25 cases), 33.4% (group B, 26 cases), and 30.8%, 15.3% (group C, 13 cases). The prognosis of group A was significantly better than that of group B (P = 0.045 by the C-M and 0.036 by the G-W test). The difference between group A and B was also significant in N0, N1 (P < 0.01), in T1, T2 (P < 0.01), and T3 (P < 0.05) cases. These results indicate that adjuvant immunotherapy using IL-2 and LAK cells in combination with chemotherapy is significantly effective in improving the postsurgical prognosis of lung cancer patients.

Abstract
Significant numbers of infiltrating mononuclear cells are commonly observed in solid tumours, although their role in restricting tumour growth is not clear. Tumour-infiltrating lymphocytes (TIL) from 38 patients with colorectal cancer, in parallel with peripheral blood lymphocytes (PBL), were assayed to determine their ability to proliferate in response to concanavalin A (ConA), interleukin-2 (IL-2), ConA+IL-2, phorbol 12-myristate 13-acetate (PMA)+ionomycin ionomycin (IOM), and staphylococcal enterotoxin B(SEB). These reagents were selected to give a range of weak to strong proliferative responses either via or independent of the T cell receptor. Proliferation of TIL was significantly lower than that of PBL in all cultures: ConA (P < 0.001), IL-2 (P = 0.002), ConA+IL-2 (P < 0.001), PMA+IOM (P < 0.001), SEB (P = 0.002). In addition to the low proliferative capacity of TIL, production of cytokines by TIL may also play a role in control of tumour growth. We have assayed IFN gamma production in the supernatants from 16 paired TIL and PBL cultures, and tumour necrosis factor alpha (TNF alpha) in 6 paired cultures. TNF alpha concentrations were significantly lower in TIL cultures than in PBL cultures stimulated with ConA (P < 0.05), but no different in control or IL-2 stimulated cultures. IFN gamma levels did not significantly differ between PBL and TIL cultures, indicating that despite the restricted proliferative capacity of TIL, these cells remain capable of secreting significant amounts of IFN gamma.

Abstract
Lymphokine-activated killer (LAK) cells generated by culture of regional lymph node cells (LNC) with interleukin 2 (IL 2) for 4 and 11 days were examined for their functional capabilities in comparison with those of peripheral blood mononuclear cells (PBM) in 25 patients with gastric carcinoma. The cytotoxic activity of LAK cells induced from LNC for 4-day culture with IL 2 was significantly lower than that from PBM. However, the LNC-LAK cytotoxicity was markedly increased up to almost the same level as that of PBM after 11-day culture. The production of interferon-gamma (INF-gamma) and tumor necrosis factor-alpha (TNF-alpha) from nonadherent LAK cells in LNC was also significantly reduced as compared to that from PBM 4 days after culture, when stimulated with or without tumor target, Raji cells. After 11-day culture with IL 2, however, the levels of these cytokines produced by LNC-LAK cells either with or without stimulation by tumor target were comparable to those by PBM-LAK cells, although the release of these cytokines was markedly reduced when compared to that after 4-day culture. Phenotypic analysis revealed decreased proportion of cells mediating NK activity in LNC before and 4 days after culture. CD56+ and CD57+ cells in LNC were increased after 11-day culture, although the percentages of these cells were still low as compared to those in PBM. The proportions of OKIa1+ and CD25+ cells were uniformly increased after 4 and 11-day culture in both cell populations. Changes in subpopulations of CD4+ and CD8+ cells in LNC were not apparently different from PBM. These results indicated the differential LAK cell function of cells from regional lymph nodes from PBM in patients with gastric carcinoma.

Abstract
In this paper we investigate the reactivity pattern of T cells from stomach carcinoma patients against autologous tumour cells. T cells obtained from the tumour environment, tumour-draining lymph nodes and peripheral blood were cloned in 78 patients with stomach cancer and anti-tumour cytotoxic T lymphocytes (CTLs) precursor frequencies were assessed in each sample by using limiting dilution analysis. When tumour-specific CTLs were tested for specific T-cell killing by using only low doses of Interleukin 2 (100 U ml-1), a moderate rate of proliferation frequency of T cells (0.047) and specific cytotoxicity (12%) were observed in lymph node populations. When both IL-2 and autologous tumour cells in mixed lymphocyte tumour cultures (MLTCs) were used for stimulation, a dramatic increase in number (0.1) and in specific lytic activity (46%) could be measured. No effect or specific activity to tumour cells was observed with peripheral blood lymphocytes and tumour-infiltrating lymphocytes.

Abstract
Lymphokine-activated killer (LAK) cells generated by culture of peripheral blood mononuclear cells (PBMC), spleen cells (SPC) and regional lymph node cells (LNC) with IL-2 for 4 days were examined for their functional capabilities in 29 patients with gastric carcinoma. The cytotoxic activity of LAK cells induced from LNC was significantly lower than that from either PBMC or SPC, although there was no difference between PBMC or SPC. The induction of mRNA of interferon-gamma (IFN-gamma) or tumour necrosis factor-alpha (TNF-alpha) and the production of these cytokines in the non-adherent LAK cells from LNC were also significantly reduced compared with those from PBMC or SPC. Further, the LAK cells from LNC secreted significantly lower levels of these cytokines when stimulated with tumour target, Raji cells, although the production of these cytokines was markedly increased by stimulation with the targets in all three cell populations. Phenotypic analysis of each cell population revealed a decreased proportion of the cells mediating natural killer (NK) activity, including CD16+, CD56+, and CD57+ cells in LNC either before or after culture, although OKIa1+ and CD25+ cells were uniformly increased in all cell populations after culture. Changes in subpopulations of CD4+ and CD8+ cells in LNC were not apparently different from PBMC or SPC. These results indicated the differential reactivity of each lymphocyte population to IL-2 and the reduced LAK cell function of LNC compared with PBMC or SPC in patients with gastric carcinoma.

Abstract
Lymphokine-activated killer (LAK) cell activity of peripheral blood mononuclear cells (PBM), spleen cells (SPC), regional lymph node cells (LNC), and tumor-infiltrating lymphocytes (TIL), induced by activation with interleukin 2 (IL 2) for 4 days, was evaluated in patients with gastric carcinoma. TIL exhibited the lowest LAK activity and the cytotoxicity of LNC was significantly lower than that of either PBM or SPC. There was no difference between PBM and SPC. Then, there were significant correlations of LAK activity among PBM, SPC, and LNC, whereas poor correlations were observed in the cytotoxicity between TIL and PBM, SPC, or LNC. Phenotypic analysis of each cell population was performed before and after activation with IL 2. Before culture, the cells mediating natural killer (NK) activity such as CD16+, CD56+, and CD57+ cells were few in LNC and TIL. However, CD56+ and CD57+ cells in TIL were increased after culture. Then, CD4+Leu8+ and CD8+CD11+ cells, which identify suppressor cell function, were not elevated in LNC or TIL, as compared to that in PBM or SPC. Further, the proportions of OKIa1+ and CD25+ cells expressing T-cell activation and IL 2 receptor were uniformly increased in all cell populations after culture. These results indicate the differential reactivity of each lymphocyte population to IL 2 and fundamental dysfunction of LNC and, especially TIL, suggesting the specific influence of the local tumor environment on the lymphocyte function in the area in patients with gastric carcinoma.

Abstract
Seventy-four patients with lung cancer, resected consecutively from April 1989 to August 1990, were divided into (1) 21 with diploid tumors having a single G0/G1 peak and a coefficient of variation (CV) of 4.9 or less, (2) 18 with peridiploid tumors having a single G0/G1 peak and a CV at 5.0 or more, and (3) 35 with aneuploid tumors having multiple G0/G1 peaks. Aneuploid tumors had higher frequencies of lymphatic invasion and metastasis to the mediastinal lymph nodes. To evaluate the relationship between ploidy tumor status and immunologic competence of the regional lymph nodes, histologic findings and the proportion of killer T-lymphocytes were examined in the dissected lymph nodes. Aneuploid tumors had significantly lower proportions of paracortical hyperplasia and killer T-lymphocytes than did diploid and peridiploid ones in the nonmetastatic lymph nodes of N0 and N1 disease. These findings suggest the possibility that a decline in the antitumor competence of these lymph nodes could cause metastasis to the nodes. The recurrence rates were 19% in diploid, 33% in peridiploid, and 54% in aneuploid tumors, and the 2-year survival rates were 87%, 78%, and 44%, respectively. Peridiploid tumors showed intermediate values between diploid and aneuploid in terms of immunologic competence, recurrence rate, and survival. They were assumed to have a different proportion of aneuploid cells than the other two.

Abstract
Cellular infiltrates of bronchoalveolar lavage (BAL) and pleural effusion from patients with tuberculosis (TB) and lung cancer were characterized for the presence of different T cell subsets by phenotypic analysis. The specificity of the T cells for mycobacterial antigens was then compared for the two disease compartments. The composition of T cell subsets within the BAL, in contrast to pleural effusion cells (PEC), revealed evidence of sequestration of CD8+ cells. BAL T cells were found to be a predominantly CD29+ DR+ memory population of activated cells. Although polyclonal populations of BAL T cells proliferated poorly to Mycobacterium tuberculosis antigens, mycobacterial antigen-reactive monoclonal T cell populations could be derived from the alveolar compartment. Two clones were shown to recognize the 65-kD heat shock protein of mycobacteria, and one of these clones recognized a conserved sequence of the molecule. Several BAL-derived clones, responding to a mycobacterial soluble extract, did not, however, recognize purified mycobacterial antigens, previously identified as highly stimulatory for PEC-derived T cells. T cell clones, derived from PEC of two TB patients, responded to the 38-kD and 71-kD, as well as the 65-kD mycobacterial antigens. Examination of the activation requirements of BAL-derived T cell clones, specific for mycobacterial antigens, revealed that exogenous IL-2 was necessary for the T cells to sustain proliferation. This was in contrast to the mycobacterial antigen-reactive T cells cloned from PEC. These results suggest that T cell populations with distinct antigen specificities and activation requirements are present in BAL and PEC.

Abstract
The soluble antitumor activity of regional lymph node cells obtained from patients with cervical cancer was investigated by using a human tumor clonogenic assay (HTCA). A significant antiproliferative activity of the lymph node cells (LNCs) against a cervical cancer cell line, HeLa cells, was demonstrated by stimulation with either phytohemagglutinin (PHA) or concanavalin A (Con A), but not with interleukin-2 (IL-2). This antiproliferative activity of LNC was found in nonadherent cells, possibly T-cells. By using neutralizing antibody experiments, this activity was found to be attributed to interferon gamma (IFN gamma), but not to tumor necrosis factor (TNF), although both cytokines were produced from LNC. These results indicate that human LNC was able to exert an antiproliferative activity mediated through the cytokines by appropriate stimulation.

Abstract
Numerous interactions between malignant and stromal/inflammatory cells take place within solid human tumours, which are mediated, in part, by the release of signalling proteins called cytokines. In the present study, we have compared the secretion of two important immunomodulatory cytokines, IFN-gamma and IL-4 by individual, immunophenotyped NK cells freshly isolated from either malignant tumour biopsies, or peripheral blood samples from patients with ductal invasive breast cancer. Due to the marked heterogeneity amongst cells isolated from these clinical samples, we have employed a technique called the reverse haemolytic plaque assay to identify and enumerate cytokine-secreting cells at the single cell level. Our data indicate that NK cells isolated directly from the tumour site secrete more IFN-gamma and IL-4 than NK cells from the blood of the same patients. However, a greater proportion of CD16+ cells from both sources in breast cancer patients secreted IFN-gamma than of those from the blood of healthy donors. We also show that factors secreted by the human breast cell lines, MCF-7 and MDA-231 PN9, were able to mimic the stimulatory influence of the tumour microenvironment on secretory activity of NK cells.

Abstract
Mononuclear cell infiltration is frequently seen within human solid tumors. Effector cells within the tumor site usually fail to exhibit cytotoxic or natural killer activity when freshly isolated; however, they develop potent and sometimes specific cytotoxicity after expansion in IL2. Thus, local tumor environment may influence lymphocyte function. In our study, we disaggregated human breast-cancer and lymph-node tissue to obtain lymphocyte-enriched cell fractions. Besides phenotypic analysis, functional characterization with regard to proliferation and cytokine production of tumor-infiltrating lymphocytes (TIL), peripheral-blood lymphocytes (PBL) and lymph-node lymphocytes (LNL) was the aim of our study. TIL showed an enrichment of CD8+ cells with a corresponding decrease in CD4+ cells in comparison with PBL and LNL. In response to PHA, TIL showed decreased 3H-thymidine uptake, but TIL were significantly stimulated by rhIL2. TIL produced low levels of IL2, TNF and IFN gamma upon mitogen/phorbol ester stimulation, while PBL produce high levels of TNF and IFN gamma but low levels of IL2. Under the same experimental conditions, LNL produce high levels of TNF and IL2 but low levels of IFN gamma. Mitogen-mediated TNF secretion was increased after addition of autologous tumor cells in TIL and LNL, whereas IFN gamma secretion tended to be suppressed. Our results indicate different patterns of activities of TIL, LNL and PBL from breast-cancer patients.

Abstract
We have studied frozen tissue from 19 oligodendrogliomas with a panel of antibodies to lymphocytes and their subsets, macrophages, natural killer cells, and HLA-Dr antigens. Macrophages were detected in moderate numbers in 60%-100% of tumors depending on the antibody used. T lymphocytes were fewer in number than macrophages and were present in 62% of cases. Most of the T lymphocytes were of the CD8 phenotype. CD4 lymphocytes were very few in number and present in only 18%. B cells and natural killer cells were absent from all cases. HLA-Dr antigens were expressed by macrophages in all cases but never on tumor cells. The implications of these findings are that macrophages and, to a lesser extent, CD8 lymphocytes are the predominant cells infiltrating oligodendrogliomas and that they may exert cellular immune functions.

Abstract
The immunological distribution of tumour-infiltrating lymphocytes (TIL), regional lymph node lymphocytes (RLNL) and peripheral blood lymphocytes (PBL) was evaluated by means of immunohistochemical staining using monoclonal antibodies of each subset of lymphocytes (stored in frozen sections) in a series of 22 patients with renal carcinoma. The immunological effect of IFN (interferon)-gamma on these immunocompetent cells was also investigated. The effect of IFN-gamma on TIL was an increase in CD3 (pan-T cells), especially an increase in CD8 (cytotoxic/suppressor-T cells). When examining these cells according to stage and grade, a marked increase in CD3 was found in low stage and low grade patients. With regard to RLNL, there was a tendency towards a decrease in CD3 and an increase in CD20 (B-cells) following the administration of IFN-gamma. No specific effect on stage and grade was observed apart from a reduction in T cell subset ratios in high grade patients. With regard to PBL, no specific trend was noted except for an increase in CD16 (NK cells) when IFN-gamma was administered.

Abstract
Alteration in interactions between tumor-infiltrating lymphocytes (TILs) and tumor cells after chemotherapy or immunotherapy was studied in metastatic melanoma patients. Tumors were harvested from surgical specimens 17 days after the end of chemotherapy with cisplatin, vinblastine, and dacarbazine (CVD). Tumors of nonlymph-node metastases from two responders yielded neither TILs nor tumor cells, whereas those from all four nonresponders had both TILs [(1.1-13.8) x 10(6) cells/g tumor] and tumor cells [(2.8-30.8) x 10(6) cells/g tumor). Tumors of lymph node metastases from nine patients yielded substantial numbers both of TILs and tumor cells, regardless of different clinical responses, except with one complete responder, whose tumor did not contain tumor cells. The mean increase of TILs from these tumors (n = 14) 3-4 weeks after incubation with 200 U/ml recombinant interleukin-2 (rIL-2) was 2.5-fold, whereas there was a 56-fold increase in TILs from untreated tumors (n = 3). CD3+ T cells predominated in TILs before and after expansion with IL-2. IL-2-activated TILs from five of six tumors tested displayed higher cytotoxicity against autologous tumor cells than against cells from any of three allogeneic tumors. Mean tumor cell numbers (10(6) cells/trial) obtained by serial needle biopsies for the same tumor in five patients decreased from 1.2 before therapy to 0.25 at day 4 of therapy (interferon alpha alone), and to 0.02 at day 8 (interferon alpha and IL-2). This decrease did not correlate with clinical responses. Yields (x 10(6) cells/g tumor) of TILs and tumor cells in subcutaneous melanomas obtained by excisional biopsies in one nonresponder under IL-2 therapy were respectively 0.2 and 1.1 before therapy (day 0), 0.1 and less than 0.01 during (day 7), 0.2 and less than 0.01 at the end of therapy (day 21), and 0.5 and 0.5 at the time of tumor progression (day 66). Yields of TILs and tumor cells in the other nonresponder were respectively 3 and 26 before (day 0), 16 and 3 during (day 7), and 0.4 and less than 0.01 at the end of IL-2 therapy (day 17), and 2.5 and 6 at the time of progression (day 62). TILs in these two patients before therapy proliferated well in culture with IL-2 (570- and 720-fold, respectively), and showed higher cytotoxicity against autologous tumor cells, whereas none of those from the five tumors biopsied during or at the end of IL-2 therapy proliferated. TILs at the time of progression showed modest proliferation (54- and 76-fold, respectively) and showed major-histocompatibility-complex-nonrestricted cytotoxicity. In summary, a decrease in the number of live tumor cells did not always correlate with clinical response in either therapy. CVD chemotherapy may simply impair IL-2-induced proliferation of TILs. IL-2 therapy may induce transient unresponsiveness of TILs to IL-2.

Abstract
Heteroconjugate (HC) antibody (anti-CD3 mAb x anti-p97 melanoma mAb) or monomeric anti-CD3 mAb by itself did not induce proliferation of uncultured melanoma tumor-infiltrating lymphocytes (TILs). They also failed to induce IL-2 production in uncultured TILs, although anti-CD3 mAb, but not HC antibody, stimulated IL-2 production in peripheral blood mononuclear cells (PBMCs). Sequential treatment of uncultured TILs from p97-antigen-positive (p97+) melanomas with HC antibody, followed by washing and incubation with interleukin-2 (IL-2), induced significantly higher proliferation than incubation with IL-2 alone. HC antibody pretreatment led to significantly greater results than with anti-CD3 mAb at a 1 ng/ml level in IL-2-induced proliferation of TILs from p97+ melanomas, similar to those with anti-CD3 mAb at a level of 100 ng/ml. HC antibody (1 ng/ml) pretreatment did not enhance IL-2-induced proliferation of either TILs from p97- melanomas or PBMCs, while anti-CD3 mAb enhanced the proliferation of TILs from some p97- melanomas and PBMCs. Regardless of the pretreatment of uncultured TILs with HC antibody or anti-CD3 mAb, IL-2-activated TILs were cytotoxic primarily only to autologous tumor cells, and their phenotypes remained the same. Thus, HC antibody can augment IL-2-induced activation of TILs only from p97+ melanomas, without altering their pattern of cytotoxicity or phenotype. The findings were consistent with observations at the clonal level. In contrast to anti-CD3 mAb, HC pretreatment of uncultured TILs from only p97+ melanoma prior to limiting-dilution analysis increased the number of proliferating TIL clones, including autologous tumor-specific cytotoxic T lymphocyte clones. These results suggest that use of HC antibody in vivo would be more advantageous than anti-CD3 mAb, with regard to augmentation of IL-2-induced TIL activation.

Abstract
Frozen sections from 30 secondary carcinomas (22 intra- and 8 extradural) were reacted with a panel of monoclonal antibodies to macrophages, lymphocytes, NK cells and HLA-Dr invariant chain. A moderate number of macrophages was demonstrated in 91% of tumours. CD 8 and CD 4 lymphocytes were detected in smaller numbers in 68% and 28% of tumours respectively. B lymphocytes were present in only one tumour and NK cells were absent. There was no significant difference between the mononuclear cell infiltrate in the intra- and extradural tumours and in respect to the histological tumour type. HLA-Dr antigen was expressed by macrophages in most cases and by tumour cells in 5/22 (22%) (4 adeno and 1 anaplastic carcinoma; of which one adenocarcinoma was extradural and the remaining intradural). The results may represent evidence for a degree of cellular immune response to secondary carcinomas which is independent of the intra- or extradural location of the tumour.

Abstract
The cytotoxin production by regional lymph node cells was examined in 25 patients with uterine cervical cancer and 10 patients with uterine myoma. The patients in stage I had significantly increased spontaneous release of cytotoxins compared with that in stages II, III, and IV. The spontaneous release in stages III and IV was markedly reduced. There was no difference in the release of cytotoxins from peripheral blood lymphocytes between cancer patients and patients with myoma or healthy controls. The cytotoxin production by lymph node cells was increased in stage III by stimulating with formalin-fixed QG-K cells derived from uterine cervical cancer, but not in stages I and II. Almost all of the cytotoxic activity of cytotoxin was abrogated by antilymphotoxin antibody. However, the cytotoxin activity was partially inhibited by anti-tumor necrosis factor antibody. These results suggest that cytotoxins released from the regional lymph node cells of uterine cancer patients are derived from, most of all, lymphotoxin.

Abstract
Lymphokine-activated killer (LAK) cell induction was evaluated in the peripheral blood mononuclear cells (PBMC) from 28 colon cancer patients and in the tumor-infiltrating leukocytes (TIL) from 20 of the patients' colon cancer specimens. Modulation of LAK cell induction in TIL and PBMC by inhibitors of arachidonic acid metabolism also was examined. LAK cells were induced in vitro in isolated TIL and PBMC by culturing with 500 U/ml of recombinant interleukin-2 (IL-2) for 3 to 5 days, and this was followed by the assessment of cytolytic activity against natural killer (NK)-resistant Chang hepatoma cells. LAK cell induction in the TIL was depressed significantly, compared with LAK cell induction in the PBMC of colon cancer patients (P less than 0.01). In the majority of cases, indomethacin augmented LAK cell induction in the TIL (P = 0.073 for the entire group, compared with cultures not treated with indomethacin) and nordihydroguaiaretic acid (NDGA) depressed LAK cell induction (P less than 0.05 for the entire group, compared with cultures not treated with NDGA). Further characterization of the mechanisms responsible for modulating LAK cell induction in the TIL of cancer patients may identify ways to optimize their use in adoptive cellular immunotherapy.

Abstract
Malignant tumors in humans are commonly associated with an inflammatory infiltrate. The mechanisms that account for the accumulation of T-lymphocytes and macrophages--these cells comprise the major components of tumor infiltrates--in the vicinity of a growing tumor are not fully understood. Tumor specific and immunogenic antigens could not be demonstrated in most solid tumors of humans, in contrast to several experimental tumor models. Thus it is not proven in human malignancies that neoantigens expressed on malignant cells are the signal which initiates an inflammatory response that, immunohistologically, is comparable to mononuclear infiltrates present in allograft rejection. A variety of nonspecific factors including lymphokines released by tumor cells may also account for the accumulation of inflammatory cells at the tumor site. The difficulties to evaluate the functional role of the "local immune response" for tumor and host are even greater. Most tumors progress in the presence of mononuclear infiltrates. Do they progress in spite of or because of the action of the local immune response? Clinical, immunopathological, and experimental data suggest that both is right, and that at least four distinct properties of tumor-associated immune reactions exist: Regression, Selection, Modulation and Progression. These distinct properties will be discussed below, using mainly the malignant melanoma of the skin as a model for a malignant tumor in humans.
