The STIC CTC study is a randomized trial to evaluate the medico-economic interest of taking into account circulating tumor cells (CTC) to determine the kind of first line treatment for metastatic, hormone-receptors positive, breast cancers. In the standard arm, the kind of treatment will be decided by clinicians, taking into account the criteria usually used in this setting. In the CTC arm, the type of treatment will be decided by CTC count: hormone-therapy if <5CTC/7.5mll (CellSearch technique) or chemotherapy if =5. The main medical objective is to demonstrate the non-inferiority of the CTC-based strategy for the progression-free survival: 994 patients are needed, and will be accrued in French cancer centers. Secondary clinical objectives are to compare toxicity, quality of life and overall survival between the two arms. The medico-economic study will compare cost per progression-free life years gained of the two strategies. The financial impact of centralized (one platform) vs decentralized (several platforms) CTC testing will be evaluated.

Further study details as provided by Institut Curie:

Primary Outcome Measures:
  • Progression free survival evaluation [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    According to RECIST 1.1 criteria

  • Economic evaluation [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Economic impact of the strategy will be evaluated (standard treatment choice vs CTC based treatment choice)

Secondary Outcome Measures:
  • Assessing patient quality of life [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    QLQC30 and BR23 individual questionaries

  • Evaluation of treatment safety according to NCI-CTCAEv4.03 [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Evaluation of both chemotherapy and hormone therapy will be recorded in CRFs whatever the randomization.

  • Overall survival evaluation [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 819
Study Start Date: February 2012
Estimated Primary Completion Date: September 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Standard
Treatment choices (hormonotherapy or chemotherapy) are done according to standard of each center based on clinical, radiological and biological information.
Biological: Circulating tumor cells counting at baseline
20 ml blood sample collected before randomization
Experimental: Circulating Tumor Cells

Treatment choices (hormonotherapy or chemotherapy) are done according to the number of CTC / 7.5 ml of blood at baseline :

If <5 CTC : Hormonotherapy If 5 or more CTC : chemotherapy

Biological: Circulating tumor cells counting at baseline
20 ml blood sample collected before randomization
