Brief Summary: This is a prospective interventional single-site research with a collection of biological samples

The primary objective of the trial is to assess the ability of the new technology to isolating circulating tumor cells CTC in selected cancer patients

Five groups will be constitued at first the Group 0 Healthy volunteers included for the spike-in test and then the four groups Group1 Metastatic HER2-positive breast cancer Group 2 Advanced CA-125 positive ovarian cancer Group 3 Metastatic PSA-positive castrate-resistant prostate cancer Group 4 Healthy volunteers included as control

In each group the percentage of cases with identified circulating tumor cells will be estimated
Detailed Description: This is a prospective interventional single-site research with a collection of biological samples Recherche Impliquant la Personne Humaine de type 2 according to French legislation

First a cohort of 20 healthy volunteers Group 0 Healthy volunteers included for the spike-in test will be constituted for the spike-in-test

Then recruitment of the three groups of 14 patients each Group1 Metastatic HER2-positive breast cancer Group 2 Advanced CA-125 positive ovarian cancer Group 3 Metastatic PSA-positive castrate-resistant prostate cancer and the control group of 14 healthy volunteers Group 4 Healthy volunteers included as control will be done in parallel

In each group the percentage of cases with identified circulating tumor cells will be estimated Success will be defined as follows the new technique has isolated putative circulating cells that have been confirmed as tumor cells by the immuno-histochemistry approach

Circulating tumor cells CTC will be identified as followed

Group 1 - putative circulating cells isolated by the new technique must be tested as HER-2 positive using Fluorescence In Situ Hybridization FISH to be regarded as true CTC
Group 2 - putative circulating cells isolated by the new technique must be tested as CA 125-positive using immuno-histochemistry IHC to be regarded as true CTC
Group 3 - putative circulating cells isolated by the new technique must be tested as PSA-positive using IHC to be regarded as true CTC For the healthy volunteers included as controls if putative circulating cells are observed these healthy volunteers will be tested against the three markers HER2 CA-125 and PSA

Failure will be defined as follows the technique failed to identify circulating tumor cells either due to a technical issue or because there was no cell identified by the new technique or lastly because the identified cells were negative by the standard FISH or IHC technique

The different characteristics of these cells will be described size cytological characteristics number etc

Secondary collected samples will be frozen and new technique for isolation of CTC will be applied a second time to describe the impact of freezing to the capacity for isolating the CTC

The primary objective of the trial is to assess the ability of the new technology to isolating circulating tumor cells CTC in selected cancer patients
