چکیده
PURPOSE To assess the safety and tolerability of preoperative cryoablation-mediated tumor antigen presentation and/or ipilimumab-mediated immune modulation in women with operable breast cancer. EXPERIMENTAL DESIGN In this pilot study, 19 women with breast cancer for whom mastectomy was planned were treated with preoperative tumor cryoablation (n = 7), single-dose ipilimumab at 10 mg/kg (n = 6), or both (n = 6). The primary outcome for this pilot study was safety/tolerability as defined as freedom from delays in pre-planned, curative-intent mastectomy. Exploratory studies of immune activation were performed on peripheral blood and tumor. RESULTS Preoperative cryoablation and/or ipilimumab were safe and tolerable, with no delays in pre-planned surgery. Grade III toxicity was seen in 1 of 19 (unrelated rash after ipilimumab). Combination therapy was associated with sustained peripheral elevations in: Th1-type cytokines, activated (ICOS+) and proliferating (Ki67+) CD4+ and CD8+ T cells, and posttreatment proliferative T-effector cells relative to T-regulatory cells within tumor. CONCLUSIONS Preoperative cryoablation and single-dose ipilimumab are safe alone or in combination with no surgical delays incurred. Potentially favorable intratumoral and systemic immunologic effects were observed with the combination, suggesting the possibility for induced and synergistic antitumor immunity with this strategy.

Pre-operative immunotherapy with tumor cryoablation (cryo) plus ipilimumab (ipi) induces potentially favorable systemic and intratumoral immune effects in early stage breast cancer (ESBC) patients
Methods Women with ESBC were treated 7-10 days preceding mastectomy with either cryo (n=6), single-dose ipi at 10mg/kg (n=6), or cryo+ipi (n=6) [6]. From serial blood (baseline & 1-month post-mastectomy) and tumor (biopsy & mastectomy), fold-changes following cryo+ipi versus monotherapy were compared (Wilcoxon ranksum) across the following measures: Ki67+ or ICOShi T-cells [2] and intratumoral ...
متن کاملRapid Health Technology Assessment of Oncotype DX in Patients with Early-Stage Breast Cancer
Introduction: Breast cancer is the most common cancer in women. Patients are treated with chemotherapy initially, and if not chemically treated, the risk of recurrence of the disease increases yearly. Therefore, methods for identifying patients for whom chemotherapy would be most beneficial are very important. The Oncotype DX test is a prognostic assay that predicts the likelihood of breast can...

Background: Pharmacogenomics is the study of genetic variations among individuals to predict the probability that a patient will respond to single or multidrug chemotherapy. Breast cancer is one of the most common cancers among women worldwide. Treatment of breast cancer by application of biological rationales gives us the ability to match the correct pharmacology to individual tumour genetic p...

Introduction: breast cancer, as the most common cancer among women, is controllable if it is diagnosed at the early stages. Breast self- examination is a simple method for early detection. One of the most important effective factors on the cancer-related mortality is the defection stage. This study was conducted to determine the relationship between breast self-examination and the disease stage...
متن کاملConcomitant Increase of OX40 and FOXP3 Transcripts in Peripheral Blood of Patients with Breast Cancer
Background: Regulatory T cells (T-regs) have an important role in cancer by suppression of protective antitumor immune responses. Regulatory T cells express the forkhead/winged helix transcription factor (FOXP3) and OX40 molecules which have important regulatory roles in the immune system. Objective: To evaluate FOXP3 and OX40 transcripts in the peripheral blood mononuclear cells of women with ...
