Abstract
The approach to disseminate renal cell carcinoma (RCC) has evolved significantly in recent years, largely owing to the progress of biologic therapy development. With increasing knowledge of biologic therapy come several dilemmas, including the choice of cytokine therapy, the appropriate mode of delivery, the selection of candidates for given therapeutic options, and the role of cytoreductive nephrectomy in immunotherapy protocols. This article reviews the historical development of immunotherapy and the lessons learned from previous experience and offers a logical approach to the patient with disseminated RCC.

Abstract
BACKGROUND Continuous local delivery of interleukin-2 (IL-2) and interferon-alpha (IFN-alpha) via gene transfer appears to be more effective than systemic therapy in preventing the growth of human renal cell carcinoma (RCC) in vitro and in vivo. To understand further if cytokine-gene transfection of RCC could alter certain cellular properties that are associated with the invasive and metastatic potentials of tumor, the authors characterized six cell lines that produce IL-2 and/or IFN-alpha in their expression of intercellular adhesion molecule-1 (ICAM-1) and CD44; binding affinity to extracellular matrix (ECM) components (fibronectin, laminin, type IV collagen, and vitronectin); and preference in forming homotypic aggregation and mRNA levels of c-myc, epidermal growth factor receptor (EGF-R), tumor transforming growth factor-beta (TGF-beta) and type IV collagenase. These six lines were compared with control vector transfected parental R11 line. METHODS The expression of ICAM-1 and CD44 was determined by fluorescence-activated cell sorter (FACS) analysis, the tumor cell binding affinity to ECM components was measured by cell attachment assay, the degree of homotypic aggregation was quantified by cell aggregation assay, and the mRNA levels of c-myc, EGF-R, TGF-beta, and collagenase were analyzed by a quantitative polymerase chain reaction analysis. RESULTS Both IL-2-gene- and IFN-alpha-gene-modified R11 exhibited enhanced expression of ICAM-1, suppression of CD44, and decreased binding affinity to ECM components, when compared with the R11-control vector. All cytokine-producing tumor lines showed a decreased preference to form homotypic aggregation. Interferon-alpha gene transfer downregulated c-myc, EGF-R, and type IV collagenase mRNA expression, whereas only the higher producers of IL-2 downregulated TGF-beta mRNA expression. Exogenous IL-2 and/or IFN-alpha treatment of a IFN-alpha-resistant RCC enhanced both HLA class I antigen and ICAM-1 expression and suppressed CD44 expression, but had no effect on tumor growth rate. CONCLUSIONS The local production of high concentrations of IL-2 and IFN-a at the tumor site may directly alter tumor properties associated with invasive and metastatic phenotypes of RCC. Interleukin-2 and/or IFN-alpha gene therapy may be an effective strategy for treatment of patients with advanced renal cancer.

Abstract
Murine systems have demonstrated improved anti-tumor efficacy when tumor-infiltrating lymphocytes (TIL) are combined with interleukin-2 (IL-2). One goal of human adoptive immunotherapy is to identify and expand TIL with specific activity against autologous tumor. In this study we attempted to isolate and characterize such cells by phenotype and cytokine expression pattern. Fourteen unselected (bulk) TIL and 5 CD8+ selected cultures were established from primary renal cell carcinoma. All cultures were grown in the presence of IL-2; triplicate cultures of each TIL culture were grown in IL-2 alone or were intermittently cocultured with irradiated allogeneic or autologous tumor. The in vitro cytotoxicity, phenotype, and cytokine expression pattern as defined by the secretion of tumor necrosis factor-alpha (TNF-alpha), interferon-gamma, granulocyte-macrophage colony-stimulating factor, IL-4, IL-6, and IL-12 were evaluated for each culture. While there was significant heterogeneity among the cultures under differing culture conditions as characterized by cytotoxicity, phenotype, and cytokine secretion pattern, we identified 8 TIL cultures which demonstrated specific enhanced lysis of only autologous tumor upon exposure to irradiated autologous tumor in vitro. These cultures demonstrate a decreased proportion of cells expressing the phenotype CD11b+. More importantly, these cultures were defined by the cytokine secretion phenotype TNF(+)/IL-6(-) upon exposure to irradiated autologous tumor. When utilized in vivo in adoptive immunotherapy of metastatic renal cell carcinoma together with IL-2, complete resolution of all metastatic tumor has only been achieved in patients who received TIL with the cytokine profile TNF(+)/IL-6(-). These findings suggest that tumor-specific renal TIL with enhanced tumor-specific cytotoxicity can be generated in vitro and can be characterized by a specific pattern of cytokine secretion. In addition, patients who receive TIL characterized by the cytokine profile TNF(+)/IL-6(-) may have an improved outcome when receiving immunotherapy.

Abstract
Patients with tumor extending through the bladder wall with invasion of adjacent structures or lymph node metastases are seldom cured by radical surgery. Preoperative chemotherapy was given to 17 patients with T3-T4, N0, N+ tumor to assess operability and long-term survival. Tumor downstaging (T0, Ta, T1, CIS, N0) occurred in 4 (80%) of the 5 T3 patients, and in 3 (25%) of the 12 patients with T4 tumors. All patients have been followed until death or for a minimum of 42 months (mean: 56 months, range 42 to 78 months). Surgery was possible in all patients. Long-term survival is realized in only 30%, suggesting that this approach did not alter the ultimate course of the natural history of the disease. Although local recurrence did not occur, 70% of the patients with downstaged cancers developed distant metastases.

Abstract
Murine models demonstrate therapeutic synergy for the combination of interleukin-2, interferon-alpha and tumor-infiltrating lymphocytes. We treated 11 patients with metastatic renal cell carcinoma with a novel regimen consisting of in vivo primed tumor-infiltrating lymphocytes, interferon-alpha and interleukin-2. Patients received interferon-alpha before radical nephrectomy; in vivo primed tumor-infiltrating lymphocytes were isolated and expanded in vitro. Low dose continuous infusion interleukin-2 at a dose of 2 x 10(6) units per m.2 per day was administered for 96 hours during each treatment week and interferon-alpha was administered as a subcutaneous injection at a dose of 6 x 10(6) units per m.2 per day on days 1 and 4 of the interleukin-2 infusion. No therapy was given during the last 3 days of a treatment week. One course of therapy consisted of 3 weeks of therapy followed by 3 weeks of rest. Patients were treated until maximal response, disease progression or dose limiting toxicity. A maximum of 6 courses of therapy were administered. Eleven patients underwent interferon-alpha priming and subsequent radical nephrectomy. In vivo primed tumor-infiltrating lymphocytes were successfully expanded in all 11 patients with an expansion index of greater than 170. In vivo primed tumor-infiltrating lymphocytes maintained their lytic activity for greater than 5 to 8 weeks in culture as demonstrated in the 4-hour 51chromium release assay. Ten patients underwent multimodality biological therapy and 3 (30%, 95% confidence interval 6 to 65%) have achieved complete response (2 clinical and 1 surgical) with durations of 24+, 23+ and 5+ months. Patients with stable disease received no additional therapy. No deaths and no grade 4 toxicities occurred. Immunotherapy using a combination of interferon-alpha primed tumor-infiltrating lymphocytes, low dose continuous infusion interleukin-2 and interferon-alpha can induce significant and durable antitumor responses in some patients with advanced renal cell carcinoma.

Abstract
BACKGROUND Interleukin-2 (IL-2) recently was approved by the Food and Drug Administration for the treatment of renal cell cancer. It is effective in a small minority of patients, but no markers identify individuals likely to respond to treatment. METHODS Two polycythemic patients with erythropoietin-producing renal cell cancer and three other polycythemic patients with renal cell cancer were treated with the combination of IL-2 and alpha-interferon (alpha-IFN). RESULTS All five patients achieved a partial or complete remission. In both patients in which it was measured, the erythropoietin level decreased significantly with treatment, and the polycythemia resolved in all patients. Hypothyroidism developed in two patients, and transient hyperthyroidism developed in another. CONCLUSION These results contrast with those achieved with IL-2 alone or in combination with lymphokine-activated killer cells, for which a 15% response rate was seen in patients with renal cell cancer and polycythemia. Although less than 5% of renal cell tumors produce erythropoietin, its production may identify a subset of individuals with renal cell cancer responsive to IL-2 and alpha-IFN.

Abstract
Interleukin-2 (IL-2) and alpha-interferon have each shown antitumor activity in patients with disseminated malignant melanoma. Because animal studies suggest enhanced activity for the combination over each agent used alone, this trial using a relatively low-dose outpatient regimen was undertaken. IL-2 at a dose of 2 x 10(6) U/m2/day (Roche units) was given by continuous intravenous infusion for 4 days a week with interferon-alpha-2a at a dose of 6 x 10(6) U/m2/day given by s.c. or i.m. injection on days 1 and 4 of each treatment week. One cycle consisted of 4 consecutive weeks of treatment followed by a 2-week rest period. Fourteen patients were entered in this study. No complete or partial responses were seen. One patient required dose reduction because of grade 3 diarrhea and two patients had interruption of treatment because of central-line-related sepsis. Fatigue was common in all patients. This low-dose combination regimen of IL-2 and alpha-interferon does not appear to be better than the single agents used alone in optimal dosage.

Abstract
The prognosis for patients with metastatic renal cell carcinoma may be brightening. Immunotherapy may offer an effective alternative approach for this disease. Continuing advances in immunology and molecular biology will probably reinforce the early enthusiasm for this method. Although still investigational, cytokine monotherapy and combination therapy, adoptive immunotherapy, and gene therapy appear to be promising therapeutic modalities for selected patients with metastatic renal cell carcinoma.

Abstract
Malignant pleural effusions are a common and significant problem in patients with advanced malignancies. Pleurodesis with tetracycline or other sclerosing agents is the usual treatment for malignant pleural effusions. In contrast to this approach, intrapleural chemotherapy has the potential advantage of treating the underlying malignancy in addition to controlling the effusion. Intracavitary cisplatin-based chemotherapy, which is cytotoxic rather than sclerosing, has proven safe and effective via the intraperitoneal route in ovarian cancer and malignant mesothelioma. There has been little previous experience, however, with intrapleural cisplatin-based chemotherapy. As part of a planned series of trials in malignant mesothelioma, the Lung Cancer Study Group first evaluated intrapleural cisplatin and cytarabine in patients with malignant pleural effusions from a variety of solid tumors. From April 1986 to November 1987, 46 patients with cytologically proven, symptomatic, and previously untreated malignant pleural effusions were entered on study. A single dose of cisplatin 100 mg/m2 plus cytarabine 1,200 mg was instilled into the pleural space via a chest tube, which was then immediately removed. Patients were evaluated for toxicity and response at 24 hours; 1, 2, and 3 weeks; and then monthly. No recurrence of the effusion was considered a complete response (CR). Partial response (PR) was defined as a 75% or greater decrease in the amount of the effusion on serial chest radiographs. One patient experienced reversible grade 4 renal toxicity, four patients had grade 3 hematologic toxicity, and five patients had grade 3 cardiopulmonary toxicity. The overall response rate (CR plus PR) at 3 weeks was 49% (18 of 37 patients). The median length of response was 9 months for a CR and 5.1 months for a PR. The outcome of this trial was sufficiently encouraging that this regimen has been incorporated into subsequent trials for malignant pleural mesothelioma.

Abstract
The bcl-1 locus on chromosome 11 at band q13 has been shown to be rearranged in some chronic B lymphoid malignancies with the t(11;14)(q13;q32). Chromosome 11 abnormalities occur in solid tumors including squamous cell cancers and adenocarcinomas. We have recently reported the frequency amplification of the bcl-1 locus in squamous cell carcinomas of head and neck origin, and increased copy number also has been found in some breast adenocarcinomas. In this investigation, we analyzed the arrangement, copy number and expression of this locus in 111 primary non-small cell lung cancers. Bcl-1 was found to be amplified three- to 10-fold in seven fresh tumors. Whereas none of 51 adenocarcinomas showed bcl-1 amplification, six of 46 squamous cell carcinomas revealed an increase in bcl-1 copy number. This amplification was more frequently associated with larger and more poorly differentiated tumors. None of the cancers showed rearrangement of this locus.

Abstract
Interleukin-2 (recombinant methionyl human interleukin-2 alanine 125; IL-2) was administered intralymphatically to 12 patients with advanced cancer in a phase I trial. Doses were administered once a week for 6 weeks in a dosage escalation schedule; patients were entered in four groups at successively higher starting dosages. Toxicity occurred in a profile similar to that seen with intravenous IL-2. The maximum tolerated dose with this route/schedule was 275,000 units/kg, a figure not higher than expected with intravenous administration. T1/2 alpha was prolonged to 54 min from the 13 min figure we obtained with IL-2 given intravenously. Granulocytosis and eosinophilia were seen, along with lymphocytosis following initial lymphopenia. Anti-IL-2 antibodies were seen in 42% of patients (compared to 16% with this agent given intravenously), suggesting increased immunogenicity of this route/schedule. No clinical response was achieved. Immunologic effects will be reported separately but are summarized.

Abstract
Three sequential studies of alpha interferon were performed in a total of 84 evaluable patients with metastatic renal cell carcinoma. In Study I, conducted from 1981 to 1982, 43 patients received human leukocyte alpha interferon (IFN alpha) 3 X 10(6) U/day, 5 days per week for 12 weeks. In Study II, performed in 1983, vinblastine (0.1 mg/kg/week) was added to the same IFN alpha regimen in 22 subjects. Study III, held from 1984 to 1985, evaluated the effects of escalating doses of interferon alfa-2a (from 3 to 36 X 10(6) U/day) administered 5 days per week to 19 patients. Overall, complete (CR) and partial responses (PR) totaled 17% (14%, 14%, and 26% in Studies I-III, respectively). Median survival of all patients was 49 weeks. Median survival appeared to be superior in the third study, likely because of the patient mix (skewed toward a Karnofsky performance status of 10, disease-free interval longer than 1 year, and disease confined to the lung). Those prognostic factors were also found to correlate with improved median survival in the total group of 84 patients. Likewise, response to therapy was linked to prolonged survival; patients with CR, PR, or minimal responses had a median survival of 72 weeks. In all the favorable subgroups, responders had better outcomes than nonresponders, but it was not clear whether response to therapy merely selected out patients with better initial prognoses or actually led to improved survival.

Abstract
Fifteen patients with advanced malignancy were treated with escalating doses of recombinant beta ser 17 interferon (IFN). Doses ranging from 0.006 to 500 X 10(6) units/m2 were administered according to a dosage escalation scheme by iv push twice weekly (starting 1 week after an initial dose) for a planned minimum of 5 weeks, to be continued as a function of response. Toxic effects were broad in scope but generally low in grade. They included fever, malaise, leukopenia, proteinuria, nausea/vomiting, diarrhea, and mild elevations of serum transaminases and creatinine. In one patient, transient hypotension with bradycardia ensued. Malaise and fever increased somewhat with increasing dose. Doses of up to 500 X 10(6) units/m2 were tolerated without severe toxicity. A maximum tolerated dose was not defined. IFN pharmacokinetics followed a biphasic decay curve, with a distribution phase alpha-half-life of 9 minutes and an elimination phase beta-half-life of 103 minutes. Anti-IFN antibodies by the ELISA technique were present in seven of 15 patients. Presence of antibody did not correlate with toxicity or response. 2',5'-Adenylate synthetase levels were increased 2 and 24 hours after the initial dose, with a trend toward higher increments with higher doses. Minimal anti-tumor responses were seen in two patients with melanoma.

Abstract
Human alpha lymphoblastoid interferon (Wellferon) was administered to 33 patients in a phase I study. Patients received Wellferon intramuscularly every 12 hours for 14 doses in nine dosage levels ranging from 0.75 X 10(6) units to 50.0 X 10(6) units. Toxicity tended to be dose dependent and included fever/chills, malaise, hematologic toxicity, and digestive tract toxicity. Thirty X 10(6) u q 12 h was felt to be the maximum tolerated dose. Three partial responses (renal cell carcinoma, diffuse histiocytic lymphoma, Hodgkin's disease) were achieved. Interferon rapidly (2 to 3 hours after the initial injection) reached peak serum levels which varied generally with dose and exceeded 500 u/ml at the 30 and 50 X 10(6) u dosages. Multiple doses of interferon resulted in cumulative peak levels substantially higher than first dose levels (greater than 500 u/ml at dosages greater than 3 X 10(6) u/ml and greater than 1,500 u/ml at dosages greater than or equal to 18 X 10(6) u). Interferon given at high dosages persisted up to 10 days beyond the final injection. Despite hematologic toxicity, inhibition of CFU-GM was not seen.

Abstract
Vinzolidine, a semisynthetic vinca alkaloid, was studied as oral therapy in 30 patients with Kaposi's sarcoma, non-small cell lung cancer, colorectal cancer, and breast cancer. Substantial variations in morbidity were observed among the patients, some patients receiving doses up to 45 mg/m2 without toxicity while others had severe hematologic toxicity at doses as low as 25 mg/m2. Nausea/vomiting and diarrhea also occurred. Responses were seen in two of 11 patients with Kaposi's sarcoma but not in other patients. Unpredictable severe hematologic toxicity led to early closure of this study. The heterogeneity of patient tolerance may relate to variable oral drug bioavailability, and it is conceivable that vinzolidine could be administered more safely by the IV route.

Abstract
An extended phase II trial of human leukocyte (alpha) interferon was done in 48 patients with measurable metastatic renal cell carcinoma, 43 of whom were evaluable. Of these patients 1 (2.5 per cent) had a complete response that was maintained after 19 months, 6 (14 per cent) had a partial response and an additional 23 per cent had either a minimal response or stabilization of previously growing metastases for greater than 3 months. Toxicity caused termination of treatment in only 1 patient and generally was tolerable. Major toxicity consisted of fever (80 per cent), fatigue (80 per cent) and hematologic toxicity (42 per cent), which was severe in only 2 patients. Characteristics of patients responding to therapy were good performance status, previous nephrectomy and metastases limited to the lungs. The results achieved with human leukocyte interferon were superior to those achieved by immunotherapy or chemotherapy at this and other institutions, and further trials are warranted.
