Active clinical trials for "Kidney Neoplasms"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy with gemcitabine and docetaxel plus filgrastim in treating patients who have locally recurrent or advanced urothelium cancer.

Although it is usually described as an immunosuppressive modality and not thought of as immunotherapy, there are new preclinical evidences suggesting that high-dose ionizing irradiation (IR) results in direct tumour cell death and augments tumour-specific immunity, which enhances tumour control both locally and distantly. Importantly, IR effects exceed the classical cytocidal properties by also causing phenotypic changes in the fraction of surviving cells, markedly enhancing their susceptibility to T cell-mediated elimination. However, not all IR-induced modifications of the tumour and its microenvironment favor immune rejection. The tumour microenvironment is populated by various types of inhibitory immune cells including Tregs, alternatively activated macrophages, and myeloid-derived suppression cells (MDSCs), which suppress T cell activation and promote tumour outgrowth. Chiang et al. showed the accumulation of pro-tumourigenic M2 macrophages in areas of hypoxia present in irradiated tumours. IR then may also induced responses that are inadequate to maintain antitumuor immunity. Close interaction between IR, T cells, and the PD-L1/PD-1 axis exsit and provide a basis for the rational design of combination therapy with immune modulators and radiotherapy. Deng et al. demonstrate that PD-L1 was upregulated in the tumour microenvironment after IR. Moreover, administration of anti-PD-L1 enhanced the efficacy of IR through a cytotoxic T cell-dependent mechanism. Concomitant with IR-mediated tumour regression, IR and anti-PD-L1 synergistically reduced the local accumulation of tumour-infiltrating MDSCs, which suppress T cells and alter the tumour immune microenvironment. Finally, activation of cytotoxic T cells with combination therapy mediated the reduction of MDSCs in tumours through the cytotoxic actions of TNF. Sagiv-Barfi et al, also demonstrated in 5 patients receiving atezolizumab and radiation therapy, at least stabilization of systemic progression in all patients and a RECIST partial response at systemic sites in 1 patient. Transient, grade 1-2 inflammatory adverse events (fevers, flu-like symptoms) occurred with no serious immune-related toxicities. Abscopal out-field effects of irradiation has also been described in addition to a reduction in circulating MDSCs in a melanoma patient treated with the anti CTLA-4 ipilimumab and radiotherapy. Lastly, recent evidence demonstrates that loco-regional curative treatment with stereotactic ablative radiotherapy (SABR) is a good alternative as compared with conventional 3D RT for patients with solid tumour, with durable remissions and a low toxicity profile. Many non-randomised studies have shown that SBRT for oligometastases is safe and effective, with local control rates of about 80%. Importantly, these studies also suggest that the natural history of the disease is changing, with 2-5 year progression-free survival of about 20%. For colorectal, non-small cell, and renal cell cancers, 1-year metastasis control rates ranged from 67 to 91%. Moreover, abscopal reponses in the setting of immune checkpoints inhibitors and radiotherapy combinations have been made in the setting of metastatic disease event in patients with extensive tumor burden. The goal of SABR is to deliver appropriate metastasis directed radiotherapy while minimizing exposure of surrounding normal tissues. Interestingly, the dose and fractionation employed modulate RT ability to synergize with immunotherapy. Vanpouille-Box et al, showed that immune response genes were differentially expressed in irradiated tumours by 8Gyx3 but not 20Gyx1. This highlight the interest of hypofractionated SABR acting as a "in situ tumour vaccine". As hypofractionated SABR may, in addition to its good local control, increase the effectiveness of anti PD-L1, investigators aimed to investigate the efficacy and the tolerability of the combination of anti-PD-L1 antibody with SABR.

Main purpose of this study is through comparing with the external control, evaluation of autologous D - CIK cells immunotherapy to finish after conventional treatment of liver cancer, renal clear cell carcinoma and nasopharyngeal carcinoma, lung cancer, colon cancer, breast cancer patients with the clinical efficacy and safety of study population, including clinical liver, renal clear cell carcinoma and nasopharyngeal carcinoma, lung cancer, colon cancer, breast cancer after conventional treatment (surgery, chemotherapy and radiotherapy) patients.The primary outcome measures were overall survival and progression-free survival, while the secondary outcome measures were overall response rate and quality of life.

Approximately 30,000 new patients are introduced into dialysis and about 20,000 of them die every year in Japan. At present, about 300,000 patients are on dialysis and more than 10,000 patients are registered to the Japan Organ Transplant Network (JOTN) with the hope for a renal transplantation. If the renal function is restored by transplantation, the quality of life (QOL) improves and more than 90% are reportedly come back to their normal life activities and get relieved from the burden of dialysis. Furthermore, it can reduce the dialysis related medical cost by as much as 50%. However, only about 1,000 renal transplantation cases are annually carried out in Japan. Among them, 80-85% are living renal transplantations offered by family members or relatives, and the rest are from deceased donors. Due to the fact that the number of deceased donors are scarce and renal transplantations between non-relatives (third parties) are currently not allowed in Japan, the approximate waiting time to receive a renal transplantation is 16 years. For that reason, many patients travel abroad to receive a renal transplantation. There are reports that total nephrectomies are performed as a treatment for small size (4 cm or less) renal tumors in many cases and that many of these nephrectomized kidneys can be successfully transplanted after surgical restoration with satisfactory results. However, due to the lack of necessary evidence it is currently not allowed in Japan. Therefore, the investigators planned the present clinical study to evaluate the curative efficacy (renal function, QOL) and safety (side effects, complications or occurence of renal cancer) of living renal transplantations between third parties (non-relatives) with restored donor kidneys after the surgical removal of a small size (4 cm or less) renal tumor, in order to acquire necessary clinical data for potential enrichment of the renal donor pool in Japan as well as to develop useful medical care for our patients who are on dialysis for many years due to the renal failure.

RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Interleukin-2 may stimulate the white blood cells to kill tumor cells. Giving bevacizumab together with interleukin-2 may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bevacizumab together with interleukin-2 works in treating patients with metastatic kidney cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so it can be removed during surgery. Giving more chemotherapy after surgery may kill any remaining tumor cells. It is not yet known which chemotherapy regimen after surgery is most effective in treating Wilm's tumor. PURPOSE: Phase III trial to study the effectiveness of chemotherapy before and after surgery in treating children who have Wilm's tumor.
