Brief Summary:

Prevention of infectious diseases through immunization is one of the greatest achievements of modern medicine. Nonetheless, considerable challenges remain for improving the efficacy of existing vaccines for therapeutic immunizations for diseases such as cancer. The investigators were amongst the first groups worldwide that introduced tumor antigen-loaded dendritic cell (DC)-based vaccines in the clinic1-3. Effective immune responses and favorable clinical outcomes have indeed been observed4-7. Thus far, mainly conventional in vitro generated monocyte-derived DCs (moDC) have been used in clinical trials worldwide. In the past 14 years the investigators have treated more than 375 patients and proven that DC therapy is feasible and non-toxic. The investigators observed that long lasting tumor specific T cell-mediated immunological responses are clearly linked to increased progression free survival as well as overall survival8.

In conclusion, based on all these observations the investigators are convinced that pDC and myDC employ different, and probably more optimal mechanisms to combat cancer. In addition, based on in vitro data and preclinical studies that suggest that blood pDC and myDC act synergistically, the investigators hypothesize that the combination of myDC and pDC may induce stronger anti-tumor immune responses as compared to pDC or myDC alone, or moDC.

Arm Intervention/treatment
Experimental: exploratory
single arm exploratory, single-centre study
Biological: Dendritic Cells for endometrial cancer
Our study population consists of 8 mEC patients who receive carboplatin / paclitaxel chemotherapy in a weekly schedule on weeks 1, 2, 3 and weeks 5,6 and 7. In week 8, myeloid and plasmacytoid DC (nDC) are loaded with tumor lysate and MUC1 and survivin PepTivators, injected intranodally. An extensive immuno-motoring will be performed on all patients. Patients who show stable disease, partial response, or full response continue with extended three-week chemotherapy regimens with intranodal injections of nDC at weeks 17, 20, and 23.

Primary Outcome Measures :
  1. Immunologic efficacy of tumor-peptide loaded nDC in mEC patients [ Time Frame: 1 year ]
    Immunomonitoring including: a) functional response and tetramer analysis of DTH infiltrating lymphocytes against tumor peptides

Secondary Outcome Measures :
  1. toxicity: Adverse Events [ Time Frame: study start till week 26 ]
    Toxicity will be assessed according to the Common Terminology Criteria for Adverse Events version 4.0

  2. Health- related Quality of Life [ Time Frame: Baseline, week 15 and week 26 ]
    Health-related quality of life, assessed using a composite of the European Organisation of Research and Treatment of Cancer (EORTC) core quality of life questionaire (QLQ C-30) of life will be assessed by the general EORTC-QLQ C30

  3. feasibility [ Time Frame: Baseline, week 8, week 17 and week 24 and week 26 ]
    number of subjects with a successful vaccination on CT scan
