Radical cystectomy under continuous antiplatelet therapy with acetylsalicylic acid.

Introduction: Aim of this study was to analyse the perioperative outcome of patients undergoing radical cystectomy under continuous antiplatelet therapy with acetylsalicylic acid.

Materials And Methods: Using prospectively maintained databases of two departments of urology, we identified 461 consecutive patients who underwent radical cystectomy for bladder cancer (2011-2017). Patients were divided into three groups: 1) on-going antiplatelet therapy with acetylsalicylic acid (n = 50), 2) discontinuing antiplatelet therapy (n = 65) and 3) no antiplatelet therapy (n = 346).

Biomodulatory Treatment of Patients with Castration-Resistant Prostate Cancer: A Phase II Study of Imatinib with Pioglitazone, Etoricoxib, Dexamethasone and Low-Dose Treosulfan.

Therapeutic options for patients with castration-resistant prostate cancer (CRPC) remain limited. In a multicenter, Phase II study, 65 patients with histologically confirmed CRPC received a biomodulatory regimen during the six-month core study. Treatment comprised daily doses of imatinib mesylate, pioglitazone, etoricoxib, treosulfan and dexamethasone.

NK-cell dysfunction in human renal carcinoma reveals diacylglycerol kinase as key regulator and target for therapeutic intervention.

The relevance of NK cells in tumor control is well established in mouse models and human hematologic malignancies; however, their contribution to the control of human solid tumors remains disputed due to problems with in situ detection and reports of functional inactivity in the tumor milieu. In this study, we established a reliable in situ detection method for NK cells. Moreover, we performed analysis to elucidate mechanisms that impair NK-cell function in the tumor milieu and thereby identify therapeutic targets that allow recovery of NK-cell functionality.

High immune response rates and decreased frequencies of regulatory T cells in metastatic renal cell carcinoma patients after tumor cell vaccination.

Our previously reported phase I clinical trial with the allogeneic gene-modified tumor cell line RCC-26/CD80/IL-2 showed that vaccination was well tolerated and feasible in metastatic renal cell carcinoma (RCC) patients. Substantial disease stabilization was observed in most patients despite a high tumor burden at study entry. To investigate alterations in immune responses that might contribute to this effect, we performed an extended immune monitoring that included analysis of reactivity against multiple antigens, cytokine/chemokine changes in serum and determination of the frequencies of immune suppressor cell populations, including natural regulatory T cells (nTregs) and myeloid-derived suppressor cell subsets (MDSCs).
