Study Details
Study Description
Brief Summary
The purpose of the study is to evaluate the benefit of adjuvant chemotherapy on overall survival for elderly patients with breast cancer, in a sub group with a high risk of relapse according to Genomic Grade test.
| Condition or Disease | Intervention/Treatment | Phase |

Phase 3 |
Detailed Description
The purpose of this trial is to address the question of the added value of adjuvant chemotherapy on survival in 70+ BC patients with ER+ disease, deemed "at risk of relapse" (pN+ or pN0 with a high prognostic classifier, namely GG by RT-PCR) and planned to receive as well adjuvant endocrine treatment. This benefit will be weighed with the competition exerted by comorbidities on mortality.
As in many recently developed trials evaluating specific strategies for the elderly (e.g. CALGB 49907 (8); bevacizumab and colorectal cancer in the PRODIGE 20 elderly program supported by the PHRC 2010), the choice of chemotherapy regimen will be left to the investigator between 3 "standard" ones: TC x 4 (no anthracyclines), AC x 4 or MC x 4 (better cardiac tolerance), in order to obtain enrolment of a less highly selected population, more representative of the general population to the difference of the high selection classically observed in standard oncology trials.
In parallel, patients not included in the randomized part (whatever reason) and treated with adjuvant endocrine treatment only will be followed up as a separate observational cohort.
-
Screening All women 70+ having undergone surgery for invasive pN0 or pN+, ER+ HER2- BC, will be screened and invited to participate. Pre-selection will be possible pre-operatively.
-
Prognostic signature After having signed a written informed consent, the prognostic signature Genomic Grade (GG) will be assessed by RT-PCR.
-
Randomization (Group I) Only the patients with a Genomic Grade (GG) considered as high will be randomized (1:1): endocrine treatment only (Arm A) versus endocrine treatment + adjuvant chemotherapy (Arm B).
Randomization1:1 between arm A and B will be done using minimization stratified according to pN status (pN+ vs pN0), G8 (≤ vs > 14), and center.
Given (i) the high potential of less cardiotoxic regimen including liposomal formulations for anthracyclines or excluding anthracyclines and (ii) the wish to capture the whole population to depict the heterogeneity of ageing from 70, adjuvant chemotherapy (Arm B) will be left to the choice of investigator amongst 3 standard regimen of same duration, 4 cycles given every 3 weeks + primary prophylactic GCSF:
-
AC = doxorubicin 60 mg/m² + cyclophosphamide 600 mg/m²
-
TC = docetaxel 75 mg/m² + cyclophosphamide 600 mg/m²
-
MC = liposomal non pegylated doxorubicin (Myocet) 60 mg/m² + cyclophosphamide 600 mg/m²
- Patients not randomized (Group II) Patients not randomized for any reason (low GG, randomization refusal or treatment refusal, etc.) will enter a surveillance program and will be able to participate to other specific geriatric studies (GERICO project to evaluate the impact of comprehensive geriatric assessment on quality of life, treatment administered and BC survival after 75 years; EORTC study to validate the scale specifically developed for elderly ELD15).
The Group II will present a triple interest and will participate, together with randomized patients, to achieve the following objectives:
-
validation of the prognostic value of Genomic Grade and performance of the test in the elderly BC population, as compared to standardized routine histopathological parameters,
-
translational studies to identify molecular signatures,
-
collection of descriptive data including comorbidities and polymedication.
- Endocrine treatment and radiotherapy In both Groups (I and II), the endocrine treatment will be left to the choice of the investigator (tamoxifen, aromatase inhibitor or sequential) and radiotherapy will follow standard guidelines.

CHEMOTHERAPY regimen will be chosen amongst the following ones: TC (docetaxel + cyclophosphamide) AC (doxorubicin + cyclophosphamide) MC (liposomal non pegylated doxorubicin [Myocet®]+ cyclophosphamide) |
Drug: CHEMOTHERAPY then HORMONOTHERAPY
CHEMOTHERAPY regimen will be chosen amongst the following ones:
i) 4 cycles of TC (docetaxel + cyclophosphamide)
Docetaxel 75 mg/m² IV infusion at hospital every 21 days
Cyclophosphamide 600 mg/m² IV infusion at hospital every 21 days
ii) 4 cycles of AC (doxorubicin + cyclophosphamide)
Doxorubicin 60 mg/m² IV infusion at hospital every 21 days
Cyclophosphamide 600 mg/m² IV infusion at hospital every 21 days
iii) 4 cycles of MC (liposomal non pegylated doxorubicin [Myocet®]+ cyclophosphamide)
Myocet® 60 mg/m² IV infusion at hospital every 21 days
Cyclophosphamide 600 mg/m² IV infusion at hospital every 21 days
HORMONOTHERAPY (Tamoxifen, aromatase inhibitor or sequential hormonotherapy) is left to the investigator judgement in both groups (I and II).

Outcome Measures
Primary Outcome Measures
- Overall survival [Median follow-up = 4 years]
The OS is defined as the interval between the date of randomization and the date of death from any cause.
Secondary Outcome Measures
- Specific overall survival [median follow-up = 4 years]
The specific OS is defined as the interval between the date of randomization and the date of death due to cancer. Alive patients or dead patients from another cause will be censored at the last follow-up
- Disease-free survival (DFS) [median follow-up = 4 years]
The DFS is defined as the interval between the date of randomization and the date of breast cancer relapse (local, regional or distant) or the date of invasive contralateral breast cancer or death from any cause, whichever occurs first.
- Event-free survival (ESF) [median follow-up = 4 years]
The EFS is defined as the interval between the date of randomization and the date of breast cancer relapse (local, regional or distant) or the date of invasive contralateral breast cancer or the date of second neoplasia, or the date of death from any cause, whichever occurs first.
- Toxicity [Throughout treatment completion, up to 4 years]
The severity of the adverse events and toxicities will be graded according the NCI CTCAE scale version 4.0.
- Geriatric Assessment [at the end of the chemotherapy in arm B or 16 weeks after the randomization in arm A (endocrine treatment only), and then each year during a 4-year follow-up period, for both arms]
the geriatric questionnaires (CCI & listing comedications, G8, IADL or MMSE) will be completed by a geriatrician or a person trained to geriatric assessment before randomization, at the end of the chemotherapy in arm B or 16 weeks after the randomization in arm A (endocrine treatment only), and then each year during a 4-year follow-up period, for both arms.
- Four-Year Mortality Index for Older Adults(Lee Score) [At the inclusion]
A 4-year mortality score including items depicting functional status, nutritional status and comorbidities, three key issues in elderly, will be systematically calculated.
- Quality of life [At baseline, week 16, 5 months, 6 months, 1 year, 2 years, 3 years, and 4 years]
Quality of life (QoL) questionnaires (QLQ C30 and QLQ-ELD15) will be completed by the patients before randomization, at the end of the chemotherapy in arm B or 16 weeks after randomization in arm A, and then each year during a 4-year follow-up period, for both arms of the group I. In case of premature end of treatment, a final Questionnary will be completed.
- Usefulness of GG by RT-PCR [two weeks after surgery (local histo. and GG test) then after inclusions are performed (central histo.)]
The prognostic signature of the GG test will be evaluated in an elderly population by comparison to standardized routine histopathological criteria and to the results obtained in the general non elderly population. In the whole cohort (n=2000) results of the GG will be compared to routine histopathological characteristics (pN, histological grade, mitotic count, Ki67 index, determination of Elston and Ellis histological grade) as determined locally or centrally for assessment of patient prognosis.
- Cost-effectiveness analysis [at the end of the chemotherapy in arm B or 16 weeks after randomization in arm A, and then each year during a 4-year follow-up period, for both arms of the group I.]
In parallel with efficacy analysis, measured by an objective clinical result indicator of state of health, such as the number of year gained (overall survival), costs for the two treatment strategies (endocrine treatment only or endocrine treatment and chemotherapy) in adjuvant systematic treatment will be also estimated. This study should provide information for decision-makers about the incremental efficacy obtained in relation to the incremental cost.
