Abstract
BACKGROUND Experiments in animal tumor models suggest that the antitumor effects of interleukin-2 (IL-2) or IL-2 in combination with lymphokine-activated killer (LAK) cells can be enhanced by chemotherapy agents such as cyclophosphamide or doxorubicin or by the biologic agent interferon alpha. PURPOSE We determined the toxicity and clinical response rate of an IL-2-LAK cell regimen modified by the addition of moderate, immunomodulatory doses of chemotherapy and sequenced with interferon alfa-2a (IFN alpha-2a) in patients with metastatic melanoma and renal cell carcinoma. METHODS IL-2 (3-6 million units/m2 per day) was administered by continuous infusion on days 0-5 and days 11-16. LAK cells were infused on days 11 and 12 or on days 11, 12, and 14. Low doses of cyclophosphamide (300 mg/m2) and doxorubicin (25 mg/m2) were given on day 9 before the LAK cell infusions. Following the IL-2-LAK cell infusion, IFN alpha-2a (12 million units/m2) was administered for a total of nine doses to complete a cycle of treatment. A total of 89 patients were enrolled in the study. RESULTS For each histology, there were eight partial responses in 40 assessable patients, for an overall response rate of 20% (90% confidence interval = 10%-33%). The median response duration was 5 months, although two patients with renal cell carcinoma and one patient with metastatic melanoma had almost complete disappearance of tumor and are still responding after 26+, 22+, and 26+ months, respectively. Toxic effects were severe in patients receiving the highest dose of IL-2 administered in this study and similar to those reported with other high-dose IL-2-LAK cell regimens. Although toxic effects were completely reversible in most patients, there were four treatment-related deaths. CONCLUSIONS This regimen is active in patients with metastatic melanoma and renal cell carcinoma and produces meaningful responses in a small percentage of these patients; however, it is not clear whether cyclophosphamide, doxorubicin, and IFN alpha-2a as used in this protocol appreciably augmented the antitumor activity of the IL-2-LAK cell regimen.

Abstract
The effect of immunotherapy with stimulated autologous lymphocytes (SAL) in malignant gliomas is documented and discussed in a bioptical and autoptical case study. A five-year-old child with a recurrently operated and radiated right hemispheric anaplastic astrocytoma died six weeks after immunotherapy with mitogen-activated killer cells and recombinant Interleukin-2. The autopsy revealed a large butterfly glioma with partially necrotic gelatinous tissue at the site of the SAL reservoir. The tumor cell density on the right was less than on the left hemisphere, and T-lymphocyte content was higher on the right hemisphere. These results demonstrate a local effect of SAL therapy in vivo, although the tumor progression as a whole could not be stopped. They also demonstrate the need of a detailed neuropathological examination in all cases of immunotherapy of malignant gliomas.

Abstract
Development of multidrug-resistance (MDR) remains a major cause of failure in the treatment of cancer with chemotherapeutic agents. In our efforts to explore alternative treatment regimens for multidrug-resistant tumors we have examined the sensitivity of MDR tumor cell lines to lymphokine activated killer (LAK) cells. Adriamycin (ADM) resistant B16-BL6 melanoma, L1210 and P388 leukemic cell lines were tested for sensitivity to lysis by LAK cells in vitro. While ADM-resistant B16-BL6 and L1210 sublines were found to exhibit at least 2-fold greater susceptibility to lysis by LAK cells, sensitivity of ADM-resistant P388 cell was similar to that of parental cells. Since ADM-resistant B16-BL6 cells were efficiently lysed by LAK cells in vitro, the efficacy of therapy with LAK cells against the ADM-resistant B16-BL6 subline in vivo was evaluated. Compared to mice bearing parental B16-BL6 tumor cells, the adoptive transfer of LAK cells and rIL2 significantly reduced formation of experimental metastases (P less than 0.009) and extended median survival time (P less than 0.001) of mice bearing ADM-resistant B16-BL6 tumor cells. Results suggest that immunotherapy with LAK cells and rIL2 may be a useful modality in the treatment of cancers with the MDR phenotype.

Abstract
Data have been analysed for 327 patients with advanced renal cell carcinoma receiving a continuous infusion of recombinant interleukin 2 (rIL-2) alone (225 patients) or rIL-2 plus lymphokine activated killer (LAK) cells (102) on a normal oncology ward. Eligibility criteria were uniform across protocols, all patients having advanced progressive disease, but with an ambulatory performance status. The baseline characteristics of patients receiving rIL-2 alone did not differ significantly from those receiving LAK, with the exception that the LAK treated patients had a better performance status. Despite similar treatment intensity, toxicity was more severe in the patients receiving LAK. The addition of LAK did not lead to higher response rates or to prolonged response duration, progression-free survival or survival. This review confirms the activity of rIL-2 for the treatment of advanced renal cell carcinoma and demonstrates that the addition of LAK cells does not lead to increased efficacy.

Abstract
Between January, 1990 and May, 1991, we administered LAK immunotherapy using the intralymphatic route to 25 patients with metastatic cancer resistant to conventional therapies. In the preparation of the immunotherapy, we followed the technique described by Pizza G. et al. The age of our patients ranged between 50 and 75 years and their Karnofsky's indexes were above 70%. The histological type of the metastasis were determined by Rx, ECO and/or CAT before and after the administration of the immunotherapy. In the intralymphatic administration, we followed the technique described by Pizza G. et al. The immunological therapy was administered on days 1, 21, 90 and 111 and the clinical response was assessed by RC, RP, EE and F. The immunological behaviour of the host was assessed through the determination of lymphoid populations (CD2, CD4, CD5 and CD8) and cytolytic cells were studied with monoclonal antibodies CD and CD16. Such immunological study was carried out before the administration of each immunotherapy series. In 7 out of 25 patients (28%), we were able to administer the four LAK series. Such patients were subsequently studied, observing that, although tumoral lesions did not increase in size, they did not disappear and, thus, they were classified as clinically stable. Clinical and analytical toxicity was null. The immunological study did not show any statistically significant changes and the activity of cytotoxic cells (NK) was not modified.

Abstract
Although the application of biological therapy for solid tumors with cytokines and adoptively transferred activated lymphocytes has received substantial attention, this approach has not been actively explored in treatment of hematopoietic neoplasms. This review will address the possibilities of interleukin-2 (IL-2) and IL-2 activated natural killer (NK) cells and T cells in antileukemia reactivity and therapy. The new approaches to optimal activation and generation of oncolytic cells, selective propagation of lymphocyte subsets, and the role of adhesion molecules in antileukemia cytotoxicity will also be addressed. We trust that this article will be conducive to the development of new directions in leukemia research and treatment.

Abstract
We investigated the activity of LAK cells in 10 patients with chronic persistent hepatitis, 20 patients with chronic active hepatitis, 21 patients with post-hepatitic cirrhosis and 21 normal persons. The values were 36.87 +/- 7.44, 30.38 +/- 5.36, 28.84 +/- 4.95 and 44.50 +/- 4.75 respectively (P < 0.05). The LAK cell activity in patients with chronic hepatitis was lower than that of normal persons, especially in those with chronic active hepatitis and post-hepatitic cirrhosis. The causes of lower LAK cell activity in patients with chronic hepatitis were less expression of IL2 receptors on precursors of LAK cells and existing serum LAK cell inhibition factors. We further studied 9 patients with chronic hepatitis B treated with autologous LAK cell transfusions. Factors favoring a more effective result were female sex, ALT elevation after treatment, activity of LAK cells > 10%, and inhibition factor of LAK effector cells existing in serum of patients, with inhibition rate < 50%. These factors might be used as the indications in selecting cases for treatment and predicting the effect of the treatment. As the number of cases observed was rather small, further investigation is needed.

Abstract
A patient with liver metastases of human lymphocyte antigen (HLA) class II-negative malignant melanoma was treated with several cycles of adoptive immunotherapy with interleukin-2 and lymphokine-activated killer (LAK) cells. The authors evaluated the efficacy of regional transfer of LAK cells versus systemic intravenous administration. Initially, the patient was treated according to a regional treatment protocol, consisting of perfusion of the spleen with interleukin-2 and transfer of LAK cells into the portal vein; a partial remission was observed. Because of technical problems, interleukin-2 and LAK cells were administered intravenously in a second treatment cycle. This systemic treatment course resulted only in a minor mixed response of the hepatic metastases. A third treatment course was administered with the use of intravenous interleukin-2 infusion and arterial perfusion of the liver with LAK cells. The patient had separate hepatic arteries to both lobes of the liver as an anatomic variation. Because most of the tumor mass was present in the right lobe of the liver, a third of the LAK cells were injected into the right hepatic artery and the remaining cells were administered intravenously. The lesions in the right lobe of the liver regressed, but disease progression occurred in the left lobe. A fourth treatment cycle, consisting of intravenous infusion of interleukin-2 and arterial perfusion of both lobes of the liver with LAK cells, resulted in a complete response of all hepatic lesions, which has lasted 18 months to date. Because, in this patient, tumor regression was observed only in anatomic areas of the liver, which were perfused with LAK cells, it is suggested that the regional administration of LAK cells was essential for successful treatment.

Abstract
High-dose recombinant interleukin-2 (rIL-2) results in tumor responses in patients with metastatic renal cell carcinoma ranging from 9 to 31%. Continuous infusion regimens of rIL-2 may be less toxic and may result in greater in vivo lymphokine-activated killer (LAK) cell production. The current trial used a continuous infusion of rIL-2 with ex vivo LAK cells. These cells were pretreated with phenylalanine methyl ester to remove monocytes to allow cell culture at higher concentrations. Twenty-three patients were entered into the trial. Two patients had complete responses (9%) lasting 15+ and 20+ months. Four patients had partial responses (17%) of 9+, 6+, 3, and 3 months, respectively. One partial responder at 9+ months had only minimal residual retroperitoneal disease that may represent scar tissue. All responders had prior nephrectomies. All but one of the responding patients completed a full cycle of rIL-2 at the highest (starting) dose, 6 x 10(6) U/m2. This rIL-2/LAK regimen appears to be an effective therapy for metastatic renal cell carcinoma.

Abstract
A 70-year-old man was admitted to our hospital on March 9, 1989 because of fever, superficial generalized lymphadenopathy, upper abdominal mass and right pleural effusion. The diagnosis of non-Hodgkin's lymphoma (follicular medium sized cell type, B cell) was made by a biopsy of the neck lymph node. Peripheral blood mononuclear cells were obtained from the patient by cytopheresis. The cells were cultured for 8 days with interleukin-2 (IL-2) to generate Lymphokine-activated killer (LAK) cells. The patient received a total of 7.7 x 10(9) LAK cells intravenously over a period of 3 weeks. He also received continuous intravenous infusion of IL-2 for 17 days, starting 2 days before the first infusion of LAK cells. After this therapy, although his superficial generalized lymphadenopathy disappeared or decreased in size, the size of the upper abdominal mass did not decrease. Therefore, it is suggested that adoptive immunotherapy is a beneficial treatments for B cell lymphoma. However, LAK cells should be generated in much larger quantities for a more successful therapeutic result.

Abstract
PURPOSE Since 1985, multiple centers have demonstrated that interleukin-2 (IL-2) and lymphokine-activated killer (LAK) cells produce durable anticancer responses in patients with metastatic renal cell carcinoma. High-dose recombinant IL-2 (rIL-2) has been administered by intravenous bolus injection (Rosenberg SA, et al: N Engl J Med 313:1485-1492, 1985) and by continuous intravenous infusion (West WH, et al: N Engl J Med 316:898-905, 1987) combined with lymphokine-activated killer (LAK) cells, with both methods producing responses in patients with advanced renal cell carcinoma. The Extramural IL-2/LAK Working Group has conducted a randomized phase II trial of two intravenous high-dose rIL-2 regimens (bolus three times daily or 24-hour continuous infusion) to determine if either one manifests greater anticancer activity or a more acceptable toxicity profile. PATIENTS AND METHODS Ninety-four patients with measurable advanced renal cell carcinoma were enrolled on this study: 46 to the bolus injection arm and 48 to the continuous infusion arm. On both arms, patients underwent a priming phase of rIL-2 administration, four daily lymphocytaphereses to harvest mononuclear cells that were placed in 3- to 4-day culture for generation of LAK cells, and an rIL-2/LAK coadministration phase. Patients were then observed monthly for evidence of response to this therapy and were offered up to two additional courses of treatment every 3 months if evidence of response was detected. RESULTS Twenty percent of patients on the bolus injection arm experienced objective responses (three complete responses and six partial responses); 15% of patients on the continuous infusion arm responded (two complete responses and five partial responses). Complete responses were durable, persisting for 310+ to 700+ days. The incidence of severe life-threatening toxicities typical of high-dose rIL-2 therapy was similar in both arms (eg, patients with hypotension requiring pressors: bolus 71%, continuous 63%; oliguria less than or equal to 200 mL/8 hours: bolus 65%, continuous 71%). More episodes of fever, infection, and serum alkaline phosphatase elevation were associated with the continuous infusion arm, while more thrombocytopenia occurred on the bolus injection arm. Four patients (three bolus injection, one continuous infusion) died of respiratory and circulatory failure while under treatment. No clinical or laboratory parameter accompanying treatment on either arm was, by univariate or multivariate analysis, associated with an increased likelihood of response. CONCLUSIONS Both methods of high-dose rIL-2/LAK cell administration produce nearly equivalent anticancer activity and toxicity in the treatment of renal cell carcinoma. The ability to predict responding patients based on patient or treatment characteristics is not possible.

Abstract
A 35-year-old woman was admitted to our hospital with a 3 month history of progressive paraparesis and impairment of bowel and bladder function. MRI suggested a malignant glioma at the level of T9 to L1. Laminectomy and subtotal removal of the tumor was performed. The surgical specimen was a glioblastoma multiforme. An aggressive adjuvant therapy was scheduled to prevent rapid local regrowth and leptomeningeal dissemination. Radiotherapy with a total dose of 65Gy was delivered with chemotherapy including ACNU (2mg/kg) and vincristine (0.2mg/kg). Lymphokine-activated killer (LAK) cells were given intrathecally with a total dose of 1.6 x 10(9) LAK cells with 3 x 10(4) units of IL-2. MRI taken 6 months after surgery revealed no residual tumor, and no malignant cell was detected in the patient's CSF. After physiotherapy, she became able to walk with a stick and was discharged. Chemotherapy (ACNU 2mg/kg/8 weeks) had been further continued for 2 years. She did well until 14 months after surgery, when paraparesis recurred and rapidly progressed to completism. MRI revealed a spinal cord swelling with marked edema, suggesting delayed radiation necrosis. Two years after surgery, MRI showed a marked atrophy of the spinal cord, and no residual tumor. But 3 years after surgery, a round tumor at the level of T11 and T12 was revealed on MRI, and she was admitted to our hospital again. A spinal cord amputation was performed, and the tumor was totally removed without worsening her neurological symptoms. Surgical specimen of the tumor was glioblastoma multiforme again.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Treatment of malignant disease with interleukin-2 and lymphokine-activated killer cells activates autoreactive T lymphocytes, stimulates release of cytokines and induces expression of HLA-class II antigens by tumour cells. We studied eight patients with hepatocellular carcinoma treated with a total of 16 courses of recombinant human interleukin-2 and lymphokine-activated killer cells and observed them for features of autoimmune thyroid disease. During the course of treatment there were significant decreases in total serum T4 and T3 and free thyroxine levels, but no change in TSH levels when all patients were analysed as a group. This was due to a number of factors including suppression of thyroid hormone release, haemodilution during interleukin-2 infusion and actual removal of thyroid hormones from the circulation during leukapheresis. Thyroid hormones returned to normal levels during resting period. One patient subsequently developed compensated hypothyroidism (normal total T4, total T3 and free T4 but elevated TSH) and four patients had features of 'sick euthyroid syndrome' (low total T4, total T3 or free T4 but normal TSH). None of the patients studied developed antibodies to thyroglobulin or microsomes. In contrast, no abnormality of thyroid function was seen in any of the nine subjects who received no active treatment. In conclusion, thyroid dysfunction was associated with immunotherapy of malignant disease with interleukin-2 and lymphokine-activated killer cells. This may arise from direct hormonal effects of the cytokines on thyroid hormone production.

Abstract
In vitro studies and animal experiments showed the existence of a physiological immune response against tumors. Interleukin-2 was the first immunological agent which demonstrated an anti-tumor effect by activating immune effectors. In vitro IL2 may generate Lymphokine Activated Killer (LAK) cells from peripheral blood lymphocytes or Tumor Infiltrating Lymphocytes (TIL) expanded from tumor. In melanoma and renal cell carcinoma, IL2 alone or associated with LAK cells or TIL, mediated clinical responses. However, their clinical efficacy was associated with some toxicity related to a capillary leak syndrome. This implies an improvement in the selection of patients and in the understanding of IL2 action. Future directions in immunotherapy included combination IL2 with other cytokines or monoclonal antibodies or chemotherapy. Lymphokine gene therapy is designed to introduce IL2 or other cytokine genes into tumor infiltrating lymphocytes or directly into tumors to reduce systemic toxicity and to achieve high local cytokine concentration. Animal models and the first human trials make this approach promising.

Abstract
PURPOSE The study was undertaken to assess whether immunotherapy regimens with bolus high-dose interleukin-2 (IL-2) alone or with lymphokine-activated killer (LAK) cells are active in previously treated, relapsed patients with non-Hodgkin's lymphoma. PATIENTS AND METHODS Nineteen patients with low- or intermediate-grade lymphomas were treated with bolus high-dose IL-2 alone (11 patients) or IL-2 with LAK cells (eight patients). IL-2 was administered by intravenous bolus infusion at 720,000 IU/kg every 8 hours. Eight patients had low-grade histologies; 11 patients were intermediate-grade. Eighteen patients had received second- or third-generation combination chemotherapy, and eight had also received radiation. All 19 relapsed after a median of two chemotherapy regimens. RESULTS Four responses were observed, three partial and one complete, in patients with follicular histologies who received IL-2 with LAK cells. Response durations were 10, 16, 16, and 26 months, and three responders were re-treated after relapse with subsequent disease control for an additional 16, 39+, and 2+ months, respectively. CONCLUSION High-dose, bolus IL-2-based immunotherapy with LAK cells may be an effective treatment for patients with non-Hodgkin's lymphoma and merits further testing with larger numbers of patients in phase II trials.

Abstract
Patients (n = 15) with metastatic malignant melanoma, hypernephroma, and colon carcinoma received a three-phase adoptive immunotherapy protocol: phase 1, 10(5) units (high-dose) interleukin-2 (IL-2) iv every 8 h or 1 mg/m2 continuous intravenous infusion; phase 2, 6.5 d rest + leukapheresis; phase 3, 4 d of high-dose IL-2 plus three infusions of autologous lymphokine-activated killer cells. Toxicities of treatment included fever, chills, tachycardia, hypotension, vomiting, diarrhea, and fluid retention. Patients entering the trial were not malnourished, and mean plasma ascorbic acid concentrations before therapy were normal (36.3 +/- 14.2 mumol/L). Mean concentrations dropped by 80% after the first phase of treatment with high-dose IL-2 alone (to 7.4 +/- 4.5 mumol/L). Mean plasma ascorbic acid concentrations remained severely depleted (between 4.5 and 7.4 mumol/L) throughout the remainder of the 15-d treatment. Ascorbic acid concentrations became undetectable (less than 2.8 mumol/L) in 12/15 patients during this time. Blood pantothenate and plasma vitamin E concentrations remained within normal limits in all patients tested throughout the phases of therapy.

Abstract
The suppressor and cytotoxic activities of mononuclear blood cells (MNC) were studied in 70 cancer patients (melanoma, renal carcinoma) undergoing adoptive immunotherapy (AIT). In the course of AIT the patients' MNC were treated in vitro with the recombinant interleukin-2 (RIL-2) in order to generate the lymphokine-activated killer (LAK) cells. Then patients received i/v 2.5-13.6 10(9) autologous LAK cells and RIL-2 (75000 u). Each course included 2-3 repeated infusions; the patients received 1-5 courses according to their clinical conditions. The cytotoxic activity of MNC was assessed by a routine method; but for evaluation of the suppressor activity we used a new technique based on separation of MNS populations in the Percoll gradient. Twenty-four hours after the completion of each AIT course the suppressor activity of MNC decreased drastically up to the zero level in some patients. The decrease in the suppressor activity inversely correlated with the rise in the cytotoxic activity on Mel-I (LAK-sensitive) and K-562 (natural killer-sensitive) target cells. The level of cytotoxicity in some patients reached 51.2%.

Abstract
The immune surveillance theory continues to remain a powerful force in cancer research and therapy despite the varying degrees of enthusiasm from both its supporters and critics. The role of both specific and non-specific immune responses in the host's defense against hepatocellular carcinoma is presented as well as the possibilities of immune-system manipulation for the prevention and therapy of this tumour.

Abstract
Ovarian cancer remains an attractive model for evaluation of biologic and immunologic therapies due to the availability of multiple reagents, the development of preclinical murine models, and the intraperitoneal pattern of clinical disease. Recent studies have focused on conjugated monoclonal antibodies, including radioconjugates, immunotoxins, and bispecific antibodies. Other preclinical and clinical studies have been conducted with recombinant cytokines and adoptive cellular immunotherapy for small-volume residual disease. Dose-limiting clinical toxicities have emerged with many of these approaches in the absence of frequent antitumor responses, and new strategies will be required to develop effective therapies in the future.

Abstract
Colonic ischemia (CI) is a rare complication of high-dose interleukin-2 (IL-2) immunotherapy. This complication occurred in three of 141 patients (2.1%) with metastatic cancer treated with high-dose IL-2 therapy; CI only developed in patients receiving interferon-alpha (IFN) with IL-2 (three of 21, 14%) compared with none of 120 in those patients receiving IL-2 alone (P equals 0.0009). Severe diarrhea (greater than or equal to 7 bowel movements/day) also was significantly more common in patients receiving IFN with IL-2 (six of 21, 29%) than in those receiving IL-2 alone (three of 120, 2.5%, P equals 0.001) and preceded the clinical diagnosis of CI in all three patients. Three of nine patients with severe diarrhea had CI. Hematochezia occurred in four patients, all of whom received IFN with IL-2; three had CI, and the other patient had nonspecific colitis. Differences in vasopressor use did not explain the increased risk of CI in patients receiving IFN; those receiving IFN with IL-2 required phenylephrine less often than patients receiving IL-2 alone (P equals 0.01). The administration of lymphokine-activated killer (LAK) cells had no significant effect on the incidence of CI, severe diarrhea, peritonitis, or vasopressor use; two of three patients with CI, however, had their ischemic episode within 24 hours after the last of three LAK cell infusions. In conclusion, CI is an unusual complication of high-dose IL-2 and IFN immunotherapy. In patients receiving such combination therapy, severe diarrhea is a risk factor for the subsequent occurrence of CI.
