Follow-up of Early Breast Cancer by Dynamic Evaluation of CEA and CA 15.3 Followed by 18FDG-PET

Not Applicable
Active, not recruiting
Conditions
Breast Cancer
Interventions
Other: Arm B, tumor markers assessment
Registration Number
NCT02261389
Lead Sponsor
IRCCS Azienda Ospedaliero-Universitaria di Bologna
Brief Summary

The main purpose of follow-up in asymptomatic breast cancer patients during and after adjuvant treatment is to detect breast cancer recurrence and metastatic disease.The aim of this trial is to verify if, in asymptomatic patients, the serial measurement of serum CEA and CA 15.3, with diagnostic imaging procedures (18FDG-PET) performed only in case of a critical increase of serum CEA and CA 15.3 level, can anticipate the diagnosis of breast cancer local and distant recurrence compared to the usual follow-up practice.

Inclusion Criteria
  • Male or female ≥18 years.

  • Histologically confirmed stage I-III epithelial breast cancer.

  • Adequate surgery of breast and axilla:

    1. patients must have undergone either a total mastectomy or breast conserving surgery
    2. surgical margins of the resected specimen must be histologically free of invasive tumor.
  • Cohort 1: if chemotherapy and/or radiotherapy are indicated the patients must be randomized between 1 month and 2 months from the end of chemotherapy and/or radiotherapy; if only hormonal adjuvant therapy is indicated the patients must be randomized within 3 months from the completion of surgery

  • Cohort 2: patients must be randomized in the trial after 5 years of follow-up without relapse (but within year 6)

  • Signed informed consent obtained prior to any study-specific procedures.

Exclusion Criteria
  • Histologically confirmed stage 0 epithelial breast cancer (carcinoma in situ).
  • Special histologies with a high or low risk of relapse (i.e. sarcoma and tubular carcinoma)
  • T1a and T1b tumors with all the following characteristics: G1-2 and N0 and RE > 10%, RPg > 10% and HER2 negative and Ki67≤14%
  • Evidence of distant metastases
  • Patients participating to other clinical trials requiring follow-up not equal to standard
  • Previous history of cancer within 5 years from randomization (except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, stage I uterine cancer, or other non-breast malignancies with an outcome similar to those mentioned above)

Arm && Interventions
GroupInterventionDescription
Arm B, tumor markers assessmentArm B, tumor markers assessmentSerum CEA and CA 15.3 performed every 3 months. No imaging studies allowed in asymptomatic patients: imaging studies (18 FDG-PET) performed only in case of critical increase of CEA and /or CA 15.3 serum levels (+100% for CEA and +75% for CA15.3), even if in the normal range.
Primary Outcome Measures
NameTimeMethod
Time interval between date of randomization and date of diagnosis of disease distant recurrenceParticipants will be followed from date of randomization until the date of first documented disease distant recurrence or date of death from any cause, whichever came first, assessed up to 60 months

Primary objective of the study is to verify if the experimental arm (serial measurement of serum CEA and CA 15.3 with diagnostic imaging procedures - i.e. 18FDG-PET- performed only in case of critical increase of serum markers level) can anticipate the diagnosis of breast cancer loco-regional (except for in-breast recurrence) or distant metastases compared to the control arm (usual follow-up practice).

Secondary Outcome Measures
NameTimeMethod
Predefined critical difference of CEA and CA15-3Participants will be followed from date of randomization until the date of first documented disease distant recurrence or date of death from any cause, whichever came first, assessed up to 60 months

Secondary objective is to evaluate the Positive Predictive Value (PPV) and the Negative Predictive Value (NPV) of CEA and CA15.3 dynamic changes in the diagnosis of breast cancer loco-regional (except for in-breast recurrence) or distant metastases.

Exploratory analysis in the different subtypesParticipants will be followed from date of randomization until the date of first documented disease distant recurrence or date of death from any cause, whichever came first, assessed up to 60 months

Secondary objective is to perform an exploratory analysis on diagnostic anticipation in the different subtypes (ER and HER2 status)

Imaging diagnostic tests evaluationParticipants will be followed from date of randomization until the date of first documented disease distant recurrence or date of death from any cause, whichever came first, assessed up to 60 months

Secondary objective is to measure how many imaging diagnostic tests will be avoided in the experimental arm compared to the control arm

Patient quality of life evaluationParticipants will be followed from date of randomization until the date of first documented disease distant recurrence or date of death from any cause, whichever came first, assessed up to 60 months

Secondary objective is to compare the quality of life in the two arms
