Project description:As one of the local treatments, cryoablation plays an increasingly important role in the comprehensive treatment of malignant tumors with its advantages of less trauma, high reproducibility, and minimally invasive. Activation of anti-tumor immunity, another characteristic of cryoablation, has attracted more and more attention with the extensive application of immunotherapy. Unfortunately, the mechanism by which cryoablation enhances anti-tumor immunity is still unclear. In this study, we used a multi-omics approach to investigate the effects of local cryoablation on the distal tumor microenvironment. In this study, we proved that large amounts of tumor antigens are released post-cryoablation, leading to a sterile inflammatory response in distant tumors. During this period, lysosome-related pathways are activated, resulting in overexpression of SNAP23 and STXBP2, activation of immune effector cells, suppression of the release of immunosuppressive factors, and finally enhancement of anti-tumor immunity. Finally, cryoablation turning “Cold tumors” into “Hot tumors”, which shows a broad prospect in the combined immunotherapy.

Project description:RATIONALE: Placing a gene into T cells may improve the body’s ability to recognize cancer cells and build an immune response to fight cancer. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine phosphate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Biological therapies, such as aldesleukin, may stimulate the immune system in different ways and stop cancer cells from growing. Giving specially treated T cells together with cyclophosphamide, fludarabine phosphate, and aldesleukin may kill more tumor cells.
PURPOSE: This phase I clinical trial is studying the side effects and best dose of treated T cells when given together with cyclophosphamide, fludarabine phosphate, and aldesleukin in treating patients with cancer.

Project description:RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Poly ICLC may stop the growth of liver cancer by blocking blood flow to the tumor. Giving the drug directly into the arteries around the tumor may kill more tumor cells. Giving cyclophosphamide and radiation therapy together with poly ICLC may be an effective treatment for liver cancer.
PURPOSE: This phase I/II trial is studying the side effects of giving cyclophosphamide, radiation therapy, and poly ICLC together and to see how well they work in treating patients with unresectable, recurrent, primary, or metastatic liver cancer.

Project description:Analysis the effect of cyclophosphamide on splenocytes gene expression. Certain chemotherapeutic drugs such as cyclophosphamide can enhance the antitumor efficacy of immunotherapy because of their capacity to modulate innate and adaptive immunity. Indeed, it has been argued that this capacity may be more significant to chemotherapeutic efficacy in general than is presently appreciated. To gain insights into the core mechanisms of chemoimmunotherapy, we methodically profiled the effects of cyclophosphamide on gene expression in bone marrow, spleen and peripheral blood, and on cytokine expression in plasma and bone marrow of tumor-bearing mice. Gene and protein expression were modulated early and transiently by cyclophosphamide, leading to upregulation of a variety of immunomodulatory factors, including danger signals, pattern recognition receptors, inflammatory mediators, growth factors, cytokines, chemokines and chemokine receptors. These factors are involved in sensing cyclophosphamide myelotoxicity and activating repair mechanisms, which, in turn, stimulate immunoactivation events that promote efficacy. In particular, cyclophosphamide induced a T helper 17 (Th17)-related gene signature associated with an increase in Th17, Th1 and activated CD25+CD4+Foxp3- T lymphocytes and a slight recovery of regulatory T-cells. By analyzing gene and protein expression kinetics and their relationship to the antitumor efficacy of different therapeutic schedules of combination, we determined that optimal timing for performing adoptive immunotherapy is approximately 1 day after cyclophosphamide treatment. Together, our findings highlight factors that may propel the efficacy of chemoimmunotherapy, offering a mechanistic glimpse of the important immune modulatory effects of cyclophosphamide Four-condition experiment, Untreated mice - Cyclophosphamide-treated mice 1 day - Cyclophosphamide-treated mice 2 days - Cyclophosphamide-treated mice 5 days. Biological replicates: 5, controls: 5, independently harvested. Two replicates per array.

Project description:The aim of this study was to evaluate in a mouse prostate cancer xenograft model the effectiveness of cyclophosphamide metronomic regimen, as single agent or in combination with standard docetaxel therapy. We used a human prostate cancer cell line to establish tumours in mice and we treated the animals with the combination of 50 mg/kg of cyclophosphamide (per os) and 30 or 10 mg/kg of docetaxel (intraperitoneally) or with the two drugs alone. We found that metronomic cyclophosphamide alone is as efficient as docetaxel in blocking tumor growth (respectively 18% and 21% of the tumor volume reached by control group in 25 days of treatment). Immunohistochemical analysis on tumours and in vitro proliferation and FACS analyses revealed that cyclophosphamide acts downregulating cell proliferation, both in vitro and in vivo. Through microarray analysis we found the upregulation of p21 that probably together with an action on the micro-environment may explain the induction of apoptosis seen in tumor xenografts. Moreover, we found 107 genes differentially expressed upon treatment with the active metabolite of cyclophosphamide and associated with functions such as cellular movement, growth, and proliferation. Cells (2 x 10^6) were seeded in T150 flasks and then treated with vehicle (ctrl), with inactive cyclophosphamide (trt) or with 5.5 M-NM-<M of active 4-Hydro peroxy cyclophosphamide (trtA) for 10, 24, and 48 hours.
