Systematic analysis of RNASET2 gene as a potential prognostic and immunological biomarker in clear cell renal cell carcinoma. BMC Cancer 2023; 23:837. [PMID: 37679715 PMCID: PMC10483861 DOI: 10.1186/s12885-023-11356-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 08/31/2023] [Indexed: 09/09/2023] Open
Abstract
BACKGROUND RNASET2 has been identified as an oncogene with anti-angiogenic and immunomodulatory effects in a variety of cancers, but its function in clear cell renal cell carcinoma (ccRCC) is still not well understood. METHODS The RNASET2 expression matrix was extracted from the The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets and analyzed for diagnostic and prognostic value. RNASET2 mRNA expression was detected by quantitative polymerase chain reaction (qPCR) in ccRCC patients and renal cancer cell lines. Wound healing assay, transwell assay, western blotting, and tube formation assays were used to evaluate the function of RNASET2 in renal cancer in vitro. In addition, transcriptome sequencing was performed on knockdown RNASET2 kidney cancer cells to analyze their potential signaling pathways. Moreover, the immune microenvironment and mutational status were evaluated to predict the potential mechanisms of RNASET2 involvement in renal cancer progression. Sensitivity to common chemotherapeutic and targeted agents was assessed according to the Genomics of Drug Sensitivity in Cancer (GDSC) database. RESULTS RNASET2 expression was significantly upregulated in ccRCC tissues and renal cancer cell lines, predicting poor prognosis for patients. In vitro experiments showed that silencing RNASET2 inhibited the migration and pro-angiogenic ability of renal cancer cells. Transcriptome sequencing suggested its possible involvement in the remodeling of the immune microenvironment in renal cell carcinoma. Furthermore, bioinformatics analysis and immunohistochemical staining showed that RNASET2 was positively correlated with the infiltration abundance of regulatory T cells. Finally, we mapped the mutational landscape of RNASET2 in ccRCC and found its predictive value for drug sensitivity. CONCLUSIONS Our results suggest that RNASET2 is a promising biomarker and therapeutic target in ccRCC.

Abstract
INTRODUCTION Although significant advances have been made in the treatment of advanced renal cell carcinoma (RCC), patients still develop resistance to standard therapies and require the administration of subsequent lines of treatment. New therapeutic approaches are thus imperative to improve the prognosis for patients with RCC. AREAS COVERED Based on the current literature, we summarize the treatment of metastatic RCC, including the use of cytotoxic chemotherapy, in this review article. We also review the existing scientific literature regarding the role of capecitabine in the treatment of RCC. EXPERT OPINION Currently, targeted therapies including vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTOR) inhibitors are widely used in the treatment of metastatic RCC. More recently, the role of immune checkpoint inhibitors has been established in the treatment of advanced RCC. Traditionally, the use of cytotoxic chemotherapy in the treatment of RCC is limited. However, cytotoxic chemotherapy may have benefit in different types of RCC, such as variant histology. Furthermore, new combinations of chemotherapy with immune checkpoint inhibitors may provide new treatment options for our patients.

Abstract
Interleukin-2 (IL-2) is a very well-known cytokine that has been studied for the past 35 years. It plays a major role in the growth and proliferation of many immune cells such NK and T cells. It is an important immunotherapy cytokine for the treatment of various diseases including cancer. Systemic delivery of IL-2 has shown clinical benefit in renal cell carcinoma and melanoma patients. However, its use has been limited by the numerous toxicities encountered with the systemic delivery. Intravenous IL-2 causes the well-known "capillary leak syndrome," or the leakage of fluid from the circulatory system to the interstitial space resulting in hypotension (low blood pressure), edema, and dyspnea that can lead to circulatory shock and eventually cardiopulmonary collapse and multiple organ failure. Due to the toxicities associated with systemic IL-2, an aerosolized delivery approach has been developed, which enables localized delivery and a higher local immune cell activation. Since proteins are absorbed via pulmonary lymphatics, after aerosol deposition in the lung, aerosol delivery provides a means to more specifically target IL-2 to the local immune system in the lungs with less systemic effects. Its benefits have extended to diseases other than cancer. Delivery of IL-2 via aerosol or as nebulized IL-2 liposomes has been previously shown to have less toxicity and higher efficacy against sarcoma lung metastases. Dogs with cancer provided a highly relevant means to determine biodistribution of aerosolized IL-2 and IL-2 liposomes. However, efficacy of single-agent IL-2 is limited. As in general, for most immune-therapies, its effect is more beneficial in the face of minimal residual disease. To overcome this limitation, combination therapies using aerosol IL-2 with adoptive transfer of T cells or NK cells have emerged.Using a human osteosarcoma (OS) mouse model, we have demonstrated the efficacy of single-agent aerosol IL-2 and combination therapy aerosol IL-2 and NK cells or aerosol IL-2 and interleukin 11 receptor alpha-directed chimeric antigen receptor-T cells (IL-11 receptor α CAR-T cells) against OS pulmonary metastases. Combination therapy resulted in a better therapeutic effect. A Phase-I trial of aerosol IL-2 was done in Europe and proved to be safe. Others and our preclinical studies provided the basis for the development of a Phase-I aerosol IL-2 trial in our institution to include younger patients with lung metastases. OS, our disease of interest, has a peak incidence in the adolescent and young adult years. Our goal is to complete this trial in the next 2 years.In this chapter, we summarize the different effects of IL-2 and cover the advantages of the aerosol delivery route for diseases of the lung with an emphasis on some of our most recent work using combination therapy aerosol IL-2 and NK cells for the treatment of OS lung metastases.

Abstract
BACKGROUND CT imaging is widely used for response evaluation of immunotherapy in patients with advanced stage renal cell carcinoma (RCC). However, this kind of treatment may not immediately be cytoreductive, although the treatment is successful. This poses new demands on imaging modalities. Positron emission tomography (PET) using (18)F-fluorodeoxyglucose (FDG) proved to be useful in monitoring the effect of several antitumour treatments. We investigated the potential of FDG-PET for the evaluation of response to immunotherapy. METHODS In seven patients with metastasized RCC, who were treated with either interferon-alpha (IFN-α) monotherapy or a combination of IFN-α, interleukin-2 and 5-fluorouracil, FDG-PET was performed prior and after 5 and 9 weeks of treatment. Quantitative changes of glucose metabolic rate (MRGlu) were compared with changes in tumour size on CT imaging using Response Evaluation Criteria in Solid Tumors (RECIST) and to survival and progression-free survival. RESULTS No consistent changes in MRGlu were observed within different response groups. And no correlation with CT imaging, neither with survival or progression-free survival, was found. CONCLUSION In contrast to the positive results reported on (chemo) therapy response evaluation with FDG-PET in different malignancies, this imaging modality appears not useful in response monitoring of immunotherapeutic modalities in RCC.

Abstract
Attenuated vaccinia virus, modified vaccinia Ankara (MVA) has been engineered to deliver the tumor antigen 5T4 (TroVax). MVA-5T4 has been evaluated in an open-label phase 2 trial in metastatic renal cell cancer patients in which the vaccine was administered alone or in combination with interferon-alpha-2b (IFN-alpha). The safety, immunologic, and clinical efficacy of MVA-5T4 with or without IFN-alpha was determined. Twenty-eight patients with metastatic renal cell cancer were treated with MVA-5T4 alone (13) or plus IFN-alpha (15). The 5T4-specific cellular and humoral responses were monitored throughout the study. Clinical responses were assessed by measuring changes in tumor burden by computed tomography or magnetic resonance imaging scan. MVA-5T4 was well tolerated with no serious adverse event attributed to vaccination. Of 23 intent-to-treat patients tested for immune responses postvaccination, 22 (96%) mounted 5T4-specific antibody and/or cellular responses. One patient treated with MVA-5T4 plus IFN-alpha showed a partial response for >7 months, whereas an additional 14 patients (7 receiving MVA-5T4 plus IFN and 7 receiving MVA-5T4 alone) showed periods of disease stabilization ranging from 1.73 to 9.60 months. Median progression free survival and overall survival for all intent-to-treat patients was 3.8 months (range: 1 to 11.47 mo) and 12.1 months (range: 1 to 27 mo), respectively. MVA-5T4 administered alone or in combination with IFN-alpha was well tolerated in all patients. Despite the high frequency of 5T4-specific immune responses, it is not possible to conclude that patients are receiving clinical benefit. The results are encouraging and warrant further investigation.

Abstract
OBJECTIVE To compare the effects of metastasectomy combined with immunotherapy and metastasectomy alone in the treatment of patients with metastatic renal cell carcinoma. MATERIALS AND METHODS A total of 93 patients who had undergone metastasectomy were included in the study. Patients were categorized according to immunotherapy status, including the immunotherapy group (n = 70) and the no immunotherapy group (n = 23). RESULTS In the immunotherapy group, median overall survival was 56.1 months (95% confidence interval [CI] 34.1-78.2), whereas the no immunotherapy group reached a median overall survival of 21.3 months (95% CI 3.4-39.2), respectively. The 1, 3, and 5-year overall survival rates were calculated at 67.1% and 56.5%, 30.0% and 34.8%, and 7.1% and 19.0%, for the immunotherapy group and the no immunotherapy group, respectively (P = 1.000). When patients were stratified according to the time of metastasis, overall survival was not significantly different among the groups in patients with synchronous metastasis or in those with metachronous metastasis. Multivariate Cox proportional hazards model analysis showed that multiplicity of metastasis (odds ratio 3.68; 95% CI 1.85-7.34; P < 0.001) and metastatic sites (odds ratio 2.12; 95% CI 1.15-3.90; P = 0.016) were independent predictors of overall survival. CONCLUSIONS Metastasectomy combined with adjuvant immunotherapy did not result in a significantly higher overall survival rate as compared with metastasectomy alone. Our findings raise the question of "Is there a role of adjuvant immunotherapy after complete metastasectomy in patients with metastatic renal cell carcinoma?"

Abstract
BACKGROUND The objective of the current study was to determine the significance of sarcomatoid differentiation as a prognostic factor for immunotherapy in metastatic renal cell carcinoma (RCC). METHODS Patients with metastatic RCC were included in this study and were categorized according to sarcomatoid differentiation. RESULTS Patients with sarcomatoid differentiation had more aggressive tumor characteristics than those without sarcomatoid differentiation. After immunotherapy, the median progression-free survival was 9.0 months (95% confidence interval [CI] 1.4-52.7) for patient without sarcomatoid differentiation and 3.2 months (95% CI 0.4-42.9) for patients with sarcomatoid differentiation, respectively (P=0.0001). The median overall survival was 22.2 months (95% CI 3.2-75.4) and 10.0 months (95% CI 0.7-60.1) in both groups. When comparing patients with sarcomatoid differentiation, there was no significant difference of overall survival in the immunotherapy group and the no immunotherapy group. Multivariate Cox proportional hazards model analysis showed that T stage (Hazard ratio [HR] 1.71; 95% CI 1.07-2.74; P=0.024), sarcomatoid differentiation (HR 2.18; 95% CI 1.30-3.66; P = 0.003), and the number of metastasis sites (HR 1.81; 95% CI 1.14-2.88; P=0.012) were independent predictors of progression-free survival. Sarcomatoid differentiation and the number of metastasis sites were independent prognostic predictors of overall survival. The estimated relative risks of sarcomatoid differentiation and the number of metastasis sites were 2.83 (95% CI 1.49-5.40; P=0.002) and 2.31 (95% CI 1.29-4.16; P=0.005), respectively. CONCLUSIONS Our findings suggest that sarcomatoid differentiation is an important prognostic factor for immunotherapy in metastatic RCC.

Abstract
In order to identify potential markers of renal cancer, the plasma membrane protein content of renal cell carcinoma (RCC)-derived cell lines was annotated using a proteomics process. One unusual protein identified at high levels in A498 and 786-O cells was CD70 (TNFSF7), a type II transmembrane receptor normally expressed on a subset of B, T and NK cells, where it plays a costimulatory role in immune cell activation. Immunohistochemical analysis of CD70 expression in multiple carcinoma types demonstrated strong CD70 staining in RCC tissues. Metastatic tissues from eight of 11 patients with clear cell RCC were positive for CD70 expression. Immunocytochemical analysis demonstrated that binding of an anti-CD70 antibody to CD70 endogenously expressed on the surface of A498 and 786-O cell lines resulted in the rapid internalisation of the antibody-receptor complex. Coincubation of the internalising anti-CD70 antibody with a saporin-conjugated secondary antibody before addition to A498 cells resulted in 50% cell killing. These data indicate that CD70 represents a potential target antigen for toxin-conjugated therapeutic antibody treatment of RCC.

Abstract
We performed a prospectively randomised clinical trial to compare the efficacy of four subcutaneous interleukin-2-(sc-IL-2) and sc interferon-alpha2a (sc-IFN-alpha2a)-based outpatient regimens in 379 patients with progressive metastatic renal cell carcinoma. Patients with lung metastases, an erythrocyte sedimentation rate < or =70 mm h(-1) and neutrophil counts < or =6000 microl(-1) (group I) were randomised to arm A: sc-IL-2, sc-IFN-alpha2a, peroral 13-cis-retinoic acid (po-13cRA) (n=78), or arm B: arm A plus inhaled-IL-2 (n=65). All others (group II) were randomised to arm C: arm A plus intravenous 5-fluorouracil (iv-5-FU) (n=116), or arm D: arm A plus po-Capecitabine (n=120). Median overall survival (OS) was 22 months (arm A; 3-year OS: 29.7%) and 18 months (arm B; 3-year OS: 29.2%) in group I, and 18 months (arm C; 3-year OS: 25.7%) and 16 months (arm D; 3-year OS: 32.6%) in group II. There were no statistically significant differences in OS, progression-free survival, and objective response between arms A and B, and between arms C and D, respectively. Given the known therapeutic efficacy of sc-IL-2/sc-INF-alpha2a/po-13cRA-based outpatient chemoimmunotherapies, our results did not establish survival advantages in favour of po-Capecitabine vs iv-5-FU, and in favour of short-term inhaled-IL-2 in patients with advanced renal cell carcinoma receiving systemic cytokines.

Abstract
The mainstay of any curative treatment in renal cell carcinoma (RCC) is surgery. In case of metastatic disease at presentation a radical nephrectomy is recommended to good performance status patients prior to start of interferon-alfa treatment. Interferon-alpha (IFN-alpha) offers in a small but significant percentage of patients advantage in overall survival; interleukin-2 (IL-2) based therapy gives similar survival rates. To date hormonal and chemotherapy do not have a proven impact on survival. The recent new insights in the molecular biology of clear RCC has revealed a key-role for vascular endothelial growth factor (VEGF) in the stimulation of angiogenesis in this highly vascularized tumour. This opens interesting new treatment strategies including: blockage of VEGF with the monoclonal antibody bevacizumab and inhibition of VEGF receptor tyrosine kinases (with small oral molecules such as SU11248 or PTK787). Likewise, inhibition of the Raf kinase pathway (with oral Bay 43-9006) or inhibition of the mTOR pathway (with i.v. CCI-779) are under investigation. Preliminary clinical results with all these compounds are interesting and the results of ongoing phase III studies will become available in the next years.

Abstract
AIM The aim of this retrospective analysis was to identify common features of long-term survivors among 218 advanced renal cell carcinoma patients sequentially entered on subcutaneous-recombinant-cytokine- based therapies between 1988 and 1993. PATIENTS AND METHODS All patients were treated with subcutaneous (s.c.) interferon-alpha2a (IFN-alpha2a) and s.c. interleukin-2 (IL-2) alone (n = 98 pts) or in combination with intravenous (i.v.) 5-fluorouracil (5-FU) (Atzpodien regimen; n = 120 pts); those patients who survived more than 10 years were classified as long-term survivors. RESULTS Thirteen patients (6.3%) were identified as long-term survivors with a median follow-up of 141 months (range, 122-174 months). According to a validated model of known clinical predictors, the long-term survivor group consisted of 6 low-risk, 5 intermediate-risk, and 2 high-risk patients, respectively. Within their clinical course, 9 longterm survivors achieved a complete response with a median duration of 141 months (range, 91-161 months), 1 patient yielded a partial remission, and 3 patients achieved stable disease. Maximum response was observed between 2 and 40 months after treatment initiation (median, 4 months), while treatment time to maximum response ranged from 2 to 14 months (median, 4 months). There was no correlation between treatment time and maximum response. Overall, long-term survivors underwent treatment for 4 and up to 80 months (median, 8 months). CONCLUSION Our data suggest that long-term survival of metastatic renal carcinoma patients beyond 10 years is independent of known clinical risk factors and treatment time. However, long-term survival of cytokine-treated, advanced renal cell carcinoma (RCC) patients remains a rare event and, thus, emphasizes the need for further investigations toward more effective therapies.

Abstract
BACKGROUND Metastatic renal cell cancer has a poor prognosis and survival. Conventional cytotoxic chemotherapy has no impact on survival and response rates are low. Biologic agents are the most active in treating this disease. We report the feasibility of administering a combination of interferon alpha, subcutaneous interleukin-2 and 5Fluorouracil in the outpatient setting to patients with metastatic renal cell cancer. RESULTS Between September 1996 and August 2003, fourteen patients were treated with this combination: ten males and four females with a median age of 50 (42-66). Thirteen patients had Eastern Cooperative Oncology Group performance scores of 0 or 1. Ten patients had had nephrectomies. Six patients had undergone prior treatments with chemotherapy or hormonal therapy. Twenty-two cycles were administered (median 1, range of 1-4). Three patients achieved partial response, eight patients had stable disease, and three had progressive disease. The duration of response in patients with stable disease was (3, 3+, 4, 4+, 5+, 6, 10, 11 months) and for the patients with a partial response was 2+, 11 and 12 months. Toxicities with this combination were predictable. There were no treatment-related deaths and no episodes of febrile neutropenia. One patient ceased treatment as a result of toxicity. Fatigue was the most common side-effect. Myalgias, fever and rigors occurred within 6-12 h of administration of interleukin-2, and resolved within 12 h. Grade 1-2 nausea and vomiting occurred in most patients. Four patients had transient asymptomatic transaminitis, which resolved spontaneously. As a result of toxicity, one patient had treatment ceased in his 6th week. CONCLUSION This combination was feasible, well tolerated and manageable in an outpatient setting.

Abstract
We report a single institution phase II study of gemcitabine 1200 mg m−2 i.v. on days 1 and 8 and capecitabine 1300 mg m−2 twice daily on days 1–14 of each 3-week cycle in patients with metastatic renal carcinoma. Patients had a WHO performance status of 0, 1 or 2. Of the 21 enrolled patients, 19 had received prior immunotherapy or chemoimmunotherapy. All had progressive disease at study entry. In all,19 patients had multiple sites of disease. The median duration of metastatic disease was 12.3 months (range 1.2–78.1 months). Three of the 19 evaluable patients achieved a partial response to treatment, with no complete responses, producing an objective overall response rate of 15.8% (95% CI, 3.4–39.6%). The median time to disease progression was 7.6 months, and median overall survival was 14.2 months. Treatment was reasonably well-tolerated, neutropenia being the most frequently observed grade 3 or 4 toxicity, occurring in 57% of patients. Other side effects were consistent with the established toxicity profile of the two drugs, including diarrhoea, palmar-plantar erythema, fatigue, nausea, vomiting and infection. This combination of gemcitabine and capecitabine has modest activity in immunotherapy-refractory metastatic renal carcinoma with manageable toxicity.

Abstract
PURPOSE OF REVIEW Highlighted in this review are the important preclinical and clinical updates of interleukin (IL)-2-based cancer immunotherapy that have been published during the last year. RECENT FINDINGS The review starts with a summary of the preclinical breakthroughs involving IL-2. The authors briefly examine two recent studies that take very different approaches to overcome the toxicities associated with IL-2 therapy. The first involves IL-2 gene transduction into tumor-infiltrating lymphocytes, and the latter discusses the use of a superoxide dismutase mimetic to ameliorate the hypotensive effects of IL-2. This is followed by a discussion of the key roles that T regulatory cells and transforming growth factor-beta have in immunosuppression, and how they interplay with IL-2. Next they review the clinical updates of IL-2 in melanoma, including IL-2 as adjuvant therapy, IL-2-based biochemotherapy, and intralesional IL-2 for soft-tissue metastases. Finally, the authors point out the recent clinical developments of IL-2 in renal cell carcinoma, including high-dose IL-2 as adjuvant therapy, and then focus on its role in the management of metastatic disease. SUMMARY IL-2 remains a valuable treatment option for patients with metastatic melanoma or renal cell carcinoma. Some of the recent updates in IL-2 therapy address important questions regarding the use of this drug, and others generate equally important hypotheses that could lead to better clinical outcomes in the future.

Abstract
In Europe, interleukin 2 (IL-2) is one of the two treatment modalities officially approved for patients with metastatic renal cell cancer. Traditionally, IL-2 has been administered by three different routes: intermittent bolus injection (BIV), continuous intravenous infusion (CIV) and subcutaneous injection (SC). There have been few randomized trials designed to compare these routes of administration. This paper describes a systematic review of the literature in which an attempt has been made to determine which schedule of administration is superior. Heterogeneity of the data makes firm conclusions difficult. It appears that the number of complete remissions (CR) is similar between BIV and SC routes and that these are higher than for CIV schedules. The durability of the CRs induced by BIV appeared superior to those induced by SC IL-2 and definitely higher than with CIV protocols. This analysis highlights some of the difficulties of using evidence-based medicine to determine standard of care when the clinical-trial data are heterogeneous. These data emphasize the importance of randomized clinical trials in determining what should be regarded as optimum therapy.

Abstract
PURPOSE The aim of this study was to retrospectively report clinical manifestations, type of treatment, survival rate of thyroid metastases from renal carcinoma. PATIENTS AND METHODS Seven patients were retrospectively collected from files of different Burgundy's hospitals. All renal and thyroid gland specimens were controlled by the anatomopathologist. RESULTS Tumors occurred in four women and three men (mean age: 66 years). Symptoms were generally a solitary mass. The metastatic tumor to the thyroid gland was the initial presentation of renal carcinoma in one case. In the other cases, patients had documented previous evidence of renal carcinoma as remotely 8.1 years before the thyroid metastases. Thyroglobulin immunohistochemistry was always negative in the foci of metastatic renal carcinoma. All patients had surgical resection of there metastasis. The majority of patients died with disseminated malignancies (mean: 38.1 months after there thyroid resection). Three patients are still alive, one after a complementary pancreatic resection for a secondary pancreatic metastasis and one other with cervical and mediastinal lymph node recurrence. CONCLUSIONS Surgical treatment of the metastatic disease is suggested, as this may prolonged patient survival.

Abstract
The association of interleukin-2 (IL-2), interferon alpha-2a (IFNalpha), 5-fluorouracil (5-FU) has been reported to induce response in metastatic renal cell carcinoma (MRCC). This study evaluated IL-2, IFNalpha and 5FU as second-line treatment after failure under immunotherapy. A total of 35 patients received IL-2, at 9 x 10(6) IU m(-2), once or t.i.d, 5 days a week, every other week. Interferon alpha was administered at 6 MUI, TIW along with IL-2 every week. 5-Fluorouracil was given at 750 mg m(-2) day(-1) on days 1-5 every 4 weeks. One cycle lasted 8 weeks. All patients were evaluable for response and toxicity. There were two objective responses (5.7%) and 14 stable diseases (40%). Survival was 14 months. In all, 17 patients experienced grade 3 toxicity. The predictive factor for progression to second-line immunotherapy was the results of first-line immunotherapy, and performance status, delay from primary tumour to metastases and response or stabilisation to chemo-immunotherapy for survival. IL-2, IFNalpha and 5-FU induce low objective response but stabilisation in patients with MRCC having failed with immunotherapy, and may be considered only in selected patients on performance status, stabilisation or response after first-line immunotherapy and interval from their primary tumour to metastases.

Abstract
PURPOSE We conducted a prospectively randomized clinical trial to compare the efficacy of three outpatient therapy regimens in 341 patients with progressive metastatic renal cell carcinoma. PATIENTS AND METHODS Patients were stratified according to known clinical predictors and were subsequently randomly assigned. Treatment arms were: arm A (n = 132), subcutaneous interferon alfa-2a (sc-IFN-alpha-2a), subcutaneous interleukin-2 (sc-IL-2), and intravenous (IV) fluorouracil; arm B (n = 146): arm A treatment combined with per oral 13-cis-retinoic acid; and arm C (n = 63), sc-IFN-alpha-2a and IV vinblastine. RESULTS Treatment (according to the standard 8-week Hannover Atzpodien regimen) arms A, B, and C yielded objective response rates of 31%, 26%, and 20%, respectively. Arm B, but not arm A, showed a significantly improved progression-free survival (PFS) compared with arm C (P =.0248). Both arm A (median overall survival, 25 months; P =.0440) and arm B (median overall survival, 27 months; P =.0227) led to significantly improved overall survival (OS) compared with arm C (median OS, 16 months). All three sc-IFN-alpha-2a-based therapies were moderately or well tolerated. CONCLUSION Our results established the safety and improved long-term therapeutic efficacy of sc-IL-2 plus sc-INF-alpha-2a-based outpatient immunochemotherapies, compared with sc-INF-alpha-2a/IV vinblastine.

Abstract
Renal cell carcinoma (RCC) is the most prevalent malignancy within the kidney and the incidence is rising. Due to improved radiological evaluation over 50% of the renal cancers are found incidentally. Despite the fact that these incidentalomas are often confined to the kidney, around 50% of all patients diagnosed with kidney cancer will develop systemic disease. Metastatic RCC has a poor prognosis. Traditional treatment modalities like chemo- and radiotherapy show overall response percentages of 2-6%. In view of the observed spontaneous remissions of advanced renal cancer, immune mechanisms have been suggested to play a role in the natural disease course of RCC. At present, several non-specific cytokine regimens are used in the treatment of mRCC, e.g. interleukin-2 and interferon-alpha, in combination or as monotherapy or in combination with substances like 13-cis-retinoic acid and/or 5-fluorouracil. Collective data of trials evaluating cytokine-based therapies for mRCC show an overall response rate of approximately 15%, with 5% of the patients showing complete responses. More importantly, cytokine treatment clearly translates into a significant survival benefit in a subset of patients. Nevertheless, the toxicity profile of these cytokine regimens is significant. With the enhanced knowledge of tumor-immunology, the identification of immunogenic tumor proteins, and antibodies recognizing tumor-associated antigens, new treatment strategies with increased specificity and fewer side effects are of interest. Here we review the different immunotherapeutical modalities currently used as well as new approaches for the treatment of advanced RCC.

Abstract
Interferon-alpha (IFNalpha) is a pleiotropic cytokine with direct and indirect antitumour effects. These include prolongation of the cell cycle time of malignant cells, inhibition of biosynthetic enzymes and apoptosis, interaction with other cytokines, and immunomodulatory and antiangiogenic effects. The first clinical trials in solid tumours used crude preparations of natural IFNalpha and demonstrated that tumour regressions in solid tumours and haematological malignancies were possible. Since the advent of genetic engineering technology, recombinant (r) IFNalpha has been widely evaluated in solid tumours. This review discusses the use and potential of rIFNalpha in solid tumours; the first part focuses on malignant melanoma and metastatic renal cell carcinoma (RCC). In the adjuvant treatment of malignant melanoma, rIFNalpha has been tested in randomised trials in more than 6000 patients. High-dosage IFNalpha (> or =10MU) prolongs disease-free survival (DFS) but not overall survival (OS). Low-dosage IFNalpha (< or =3MU) has not been shown to prolong DFS or OS, and current data do not support its use outside clinical trials. The latest United Kingdom Co-ordinating Committee on Cancer Research meta-analysis of ten randomised trials that used adjuvant rIFNalpha has shown that there is a benefit in DFS but not OS. No conclusions can be reached for intermediate-dosage IFNalpha (5 to 10MU) until the mature results of the European Organization for Research and Treatment of Cancer (EORTC) study 18952 are available. In RCC, current evidence does not support the use of adjuvant IFNalpha. In metastatic malignant melanoma and RCC, reported response rates to rIFNalpha are approximately 15%. In a minority of responding patients, however, these responses can be long-standing. In metastatic malignant melanoma, IFNalpha combined with other cytotoxic agents with or without interleukin-2 has achieved high response rates but has not improved survival. In metastatic RCC, intermediate dosages of rIFNalpha should be used and therapy should probably be prolonged (>12 months); response depends on prognostic factors such as good performance status, whereas survival is affected by factors such as low tumour burden. Nephrectomy should therefore be considered in patients with good performance status prior to IFNalpha immunotherapy in advanced RCC, even in patients with metastatic disease. The toxicity of high-dosage IFNalpha and the lack of definite benefit on OS with high- or low-dosage IFNalpha do not support its use outside clinical trials. Data from the ongoing US Intergroup studies, the ongoing EORTC 18991 study (long-term therapy with pegylated IFNalpha) and mature data from EORTC 18952 (intermediate-dosage IFNalpha) will help establish the role of IFNalpha as adjuvant therapy in malignant melanoma.

Abstract
BACKGROUND The main objective of this trial was to evaluate the combination of subcutaneous (SC) interleukin-2 (IL-2) with interferon alpha-2a (IFN-alpha) in the treatment of patients with metastatic renal cell carcinoma (MRCC) compared with a previous trial that used continuous-infusion IL-2 and IFN-alpha with identical schedules and dosages. METHODS Between April, 1997 and January, 1998, 66 patients with MRCC received SC IL-2 at a dose of 9 x 10(6) IU/m(2) twice daily for 5 days during 2 induction cycles and during 4 additional cycles, with a 3-week rest between cycles. Each induction cycle consisted of two 5-day courses of IL-2 separated by a 9-day break. IFN-alpha at a dose of 6 x 10(6) IU per day three times per week was given during induction cycles and additional cycles. RESULTS All patients were assessable for response and toxicity. The median follow-up was 43 months. Thirty-five patients (51%) and 43 patients (63%) received >or= 80% of the planned induction doses of IL-2 and IFN-alpha, respectively. Five patients achieved objective responses (7.6%; 95% confidence interval [95%CI], 2.5-16.8%), with two complete responses. The median survival was 14 months (95%CI, 11.3-16.7 months). Fifty-three patients (80%) had at least one episode of Grade 3 toxicity related to treatment. Twenty-two patients developed Grade 4 toxicities, which included hypotension (24% of patients), decreased performance status (6% of patients), dyspnea (3% of patients), and mucositis (3% patients) as well as fever, ventricular tachycardia, and anemia. CONCLUSIONS The current results seem to indicate reduced efficacy and higher toxicity rates with SC IL-2 plus IFN-alpha compared with the results from a previous trial that used an identical regimen with IV IL-2 administration. Although SC IL-2 regimens are used widely, their interest remains to be determined.

Abstract
BACKGROUND The current study evaluated the efficacy and toxicity of interleukin-2 (IL-2), interferon-alpha (IFN-alpha), 5-fluorouracil (5-FU), and vinblastine (VBL) in the treatment of metastatic renal cell carcinoma (MRCC). METHODS Sixty-two MRCC patients, median age 63 years, received immunochemotherapy. Eastern Cooperative Oncology Group performance status was 1 for 45 patients and 2 for 17 patients. Fifty-four patients underwent nephrectomy prior to treatment. Sites of disease were lungs, lymph nodes, bone, kidney, and liver. Treatment consisted of IL-2 10 MIU/m(2) subcutaneous (SC), three times per week, Weeks 1-4; IFN-alpha 6 MIU/m(2) SC, once per week, Weeks 1-4 and 9 MIU/m(2), three times per week, Weeks 5-7; 5-FU 600 mg/m(2) and VBL 6 mg/m(2), intravenous bolus, Day 1 of Weeks 5 and 7. RESULTS In a median followup of 34 months, 62 patients were evaluated for tumor response. Four patients achieved complete response for 26+, 34+, 51+, and 56+ months, respectively; 14 patients achieved partial response for a median of 14 months; and 20 patients achieved stable disease for a median of 9 months. Seven patients (5 partial response, 2 stable disease) underwent complete resection of residual tumor. Five patients remained alive with no evidence of disease for 27, 32, 36, 42, and 48 months, respectively. Nine patients achieved long-term complete response for a median of 36 months. Three-year survival rate for the entire group and for 11 complete responders was 88%. Common side effects were flu-like symptoms, nausea, headache, and depression. Four patients were excluded because of treatment intolerance, and one patient died after nephrectomy. CONCLUSIONS Immunochemotherapy is effective and well-tolerated by patients with MRCC. Surgical intervention for resection of residual disease is justified.

Abstract
PURPOSE Since metastatic renal cell carcinoma has a poor prognosis and treatment strategies, including hormone therapy, chemotherapy and immunotherapy, have little impact on the quality of life and global survival statistics, new interest has recently focused on the combination of immuno-chemotherapy using pyrimidine analogues, such as gemcitabine. MATERIALS AND METHODS In a phase II study 16 patients with metastatic renal cell carcinoma were treated with 1,000 mg./m. gemcitabine intravenously on days 1, 8, 15 and 28 for 6 months, 3 MU (1 MU = 1 x 10(6) IU) interferon (IFN)-alpha intramuscularly 3 times a week and 4.5 million IU interleukin (IL)-2 subcutaneously daily for 5 days a week for 2 consecutive weeks every month for 6 months. Responding and nonprogressing cases were maintained on immunotherapy consisting of IFN-alpha and IL-2 for further 6 months. RESULTS In 15 evaluable patients overall response rate (1 complete response plus 3 partial response) was 28% while stable disease was achieved in 7 (47%). Median survival duration was 20 months (range, 9 to 26+) and median time to tumor progression was 14 months (6 to 26+). The complete response lasted 24+ months and partial response lasted 16 months. The regimen was well tolerated with only 1 case of neutropenia (WHO grade 3), while anorexia, fatigue and flu-like symptoms were the most common toxicity problems but were never greater than grade 2. CONCLUSIONS Despite the small sample size, this study demonstrates that gemcitabine combined with standard doses of IFN-alpha and low doses of IL-2 is effective treatment for metastatic renal cell carcinoma. This biotherapy was well tolerated and resulted in an optimum objective response and relatively long-term survival.

Abstract
Interferons are agents with antiviral, antiproliferative, and immunomodulatory properties. Interferon-alfa (IFN-alpha) is used in the treatment of hematologic malignancies and solid tumors. IFN-alpha has shown antitumor and antiviral efficacy that are not correlated, one with another. Approval by the US Food and Drug Administration was granted early for the treatment of patients with hairy cell leukemia, acquired immune deficiency syndrome-related Kaposi's sarcoma, and condylomata acuminata. Although IFNs are effective as single agents in certain clinical pathologic entities, increasing experience with these cytokines suggests that their greatest therapeutic potential may be realized in combination with other biological response modifiers, cytotoxics, or antiviral agents. For example, trials combining IFN-alpha with 5-fluorouracil to treat colorectal carcinoma or IFN-alpha with zidovudine to treat acquired immune deficiency disorder showed increased efficacy over IFN-alpha alone. While IFN-alpha appears to be moderately effective in certain diseases, the flu-like syndrome associated with its use is a major limiting factor for its clinical application. Further studies are needed to determine the underlying mechanism of action for IFNs and the most effective combinations and appropriate preclinical models, or intermediate endpoints that will then facilitate the rational use of this agent in combinations based on the mechanisms of action of IFN-alpha.

Abstract
BACKGROUND The objective of this study was to determine the response rate and toxicity of gemcitabine and continuous-infusion 5-fluorouracil (5-FU) in combination with subcutaneous interleukin-2 (IL2) and interferon-alpha (IFNA) in patients with metastatic renal cell carcinoma. METHODS Forty-one patients were treated with gemcitabine 600 mg/m2 on Days 1, 8, and 15 and continuous-infusion 5-FU on Days 1-21. The dose of 5-FU was 200 mg/m2 per day for the initial 8 patients but was reduced to 150 mg/m2 per day for all remaining patients due to toxicity. Starting on Day 15, IL2 and IFNA were administered for 4 weeks. IL2 was administered at a dose of 11 x 10(6) IU subcutaneously (s.c.) 4 days per week and IFNA was administered at a dose of 10.0 x 10(6) IU s.c. 2 days per week. RESULTS Of 41 patients enrolled in the study, there was 1 complete response (CR), and there were 5 partial responses (PR), for an overall response rate of 14.6% (90% confidence interval [90%CI], 6.6-26.9%). The median time to disease progression was 6.6 months (90%CI, 3.9-7.5 months), and the median overall survival was 20.6 months (90%CI, 9.6-23.3 months). Toxicity was moderate to severe, with fatigue, fever, anorexia, or nausea experienced by 75-90% of patients. Mucositis and neutropenia, likely due to the gemcitabine and 5-FU, were experienced by a majority of patients. CONCLUSIONS The addition of gemcitabine and 5-FU to subcutaneous IL2 and IFNA results in a similar response rate to what was observed in previous studies of IL2-based therapy. The toxicity of this four-drug combination is significant, and the regimen is not recommended for further development.

Abstract
BACKGROUND The treatment of metastatic renal cell cancer remains unsatisfactory despite encouraging results with biotherapy. Pilot studies from other investigators have suggested that combining cis-retinoic acid and 5-fluorouracil (5FU) with interleukin-2 (IL-2) and interferon-alpha (IFN) may improve outcomes for such patients. METHODS Eligible patients had metastatic renal cell cancer, were in good medical condition, and had not been treated previously with more than two of the study agents. A 56-day treatment cycle consisted of: interferon-alpha 2a 3.0 mu/m2 s.c. Monday, Wednesday, and Friday weeks 1-8, interleukin-2 11 mu/m2 s.c. Tuesday, Thursday and Saturday of weeks 1-4, cis-retinoic acid 1 mg/kg p.o. daily weeks 1-8, and 5-FU 750 mg/m2 i.v. weekly during weeks 5-8. Patients were evaluated for tumor response every 8 weeks, and in the absence of tumor progression, patients could receive treatment for up to one year. Survival was determined from the first date of treatment. RESULTS The 58 renal cell carcinoma patients included 41 men and 17 women, with a median age of 57 years with a range of 28-85 who were enrolled between October 1994 and July 1997. Thirty-seven percent were asymptomatic when treatment was initiated. Sites of disease at study entry included 62% lung, 34% bone, 31% lymph node, 22% kidney, 16% liver and 10% adrenal. There were only three patients with significant tumor responses (one complete, two partial) for a response rate of 5% (0-11% 95% CI) based on intent-to-treat analysis, and 6% (0-12%, 95% CI) for the 53 patients who were evaluable for response. The response rate among evaluable nephrectomized patients who had received no prior radiation or systemic treatment was 3/25 (12%). The median failure-free survival was 2.8 months; median overall survival was 10.9 months. The 1-year survival rate was 50% and 2-year survival rate was 33%. The most frequent toxicities were fatigue-81% (26% grade 3 or 4), nausea/vomiting-59%, and leukopenia/neutropenia 57% (16% grade 3 or 4). CONCLUSION Despite a disappointing objective response rate, survival in these patients who were treated entirely as outpatients was similar to that seen in our earlier trials of inpatient, intermediate dose continuous infusion IL-2-based therapy.

Abstract
Metastatic renal cell carcinoma has a poor prognosis. The value of immunotherapy with IFN-alpha and IL-2 both as single agent or as the combination is extensively investigated. The optimal dose and schedule is not known. In various studies response rates vary between 10 and 40%. The duration of response is variable. For a partial response a median duration between 10 and 12 months is given. Complete responses are sometimes long-lasting (a couple of years). The toxicity is drug, dose and schedule dependent. On the basis of a number of prognostic factors, such as performance score, time between the initial diagnosis and the treatment of metastases and the number of metastatic sites, patients can be divided in different prognostic groups. Patients who are classified in the good or intermediate prognostic group may have an improvement of their survival after immunotherapy and therefore they are candidates for immunotherapy.

Abstract
After nephrectomy for renal cell carcinoma (RCC), a significant number of patients develop recurrent disease. In order to improve the prognosis of these patients, the role of adjuvant immunotherapy should be clarified; the appropriate selection of patients is especially crucial. For this purpose, the search for prognostic factors is important to identify at-risk patients. Known factors such as stage, grade, and microvascular invasion can be used for appropriate selection. Other molecular markers, such as cadherin-6 and G250 antigen, may become important. So far, adjuvant immunotherapy in RCC has not shown improved survival data, but the results may be hampered by inadequate recruitment and follow-up. Adequate selection of patients and the search for less toxic and more effective immunotherapy approaches are of importance. Therefore, the use of monoclonal antibody G250 or dendritic cell vaccinations, alone or together with cytokines, may be advantageous and is currently used. Today, adjuvant protocols are open for recruitment of patients to elucidate the important question as to whether this approach should be implemented in the treatment of RCC. In this article, an update is given in the field of adjuvant immunotherapy in patients with RCC.

Abstract
We conducted a prospectively randomized clinical trial to compare the efficacy and safety of subcutaneous interferon-alpha2a, subcutaneous interleukin-2 and intravenous 5-fluorouracil as home therapy against oral tamoxifen in 78 patients with progressive metastatic renal cell carcinoma. Treatment courses consisted of interferon-alpha2a 5 x 10(6) IU m(-2), day 1 weeks 1 + 4; days 1, 3, 5 weeks 2 + 3; 10 x 10(6) IU m(-2), days 1, 3, 5 weeks 5-8; interleukin-2 10 x 10(6) IU m(-2), twice daily days 3-5 weeks 1 + 4; 5 x 10(6) IU m(-2), days 1, 3, 5 weeks 2 + 3; and 5-fluorouracil 1000 mg m(-2), day 1 weeks 5-8. The tamoxifen group received tamoxifen 80 mg twice daily over 8 weeks. Among 41 patients treated with interleukin-2, interferon-alpha2a and 5-fluorouracil there were 7 complete (17.1%) and 9 partial responders (21.9%), with an overall objective response rate of 39.1% (95% CI, 24.2-55.5). An additional 15 patients (36.6%) were stable throughout therapy. The overall survival was 24 months (range 5-76+). In 37 patients receiving tamoxifen no objective remissions occurred. 13 patients (35.1%) had stable disease and 24 patients (64.9%) showed continued disease progression. The overall survival was 13 months (range 3-73+). In summary, this home-based therapy regimen of interferon-alpha2a, interleukin-2 and 5-fluorouracil demonstrated significant therapeutic efficacy in patients with progressive renal cell carcinoma when compared to hormonal therapy.
