Abstract

This section provides current contact details and a summary of recent or ongoing clinical trials being coordinated by Scandinavian Breast Group (SBG). Clinical trials include:

  1. High-dose chemotherapy + autologous stem cell transplantation compared with dose escalating chemotherapy in breast cancer with poor prognosis ≥ 8 positive lymph nodes or ≥ 5 lymph nodes combined with R-combined with either G II–III or high S-phase. A randomized study. SBG 9401

  2. Standard CEF-60 versus tailored CEF in high-risk primary breast cancer. SBG CEF-60, SBG 2000-1

  3. HABITS – Hormonal replacement therapy after breast cancer diagnosis – is it safe? BIG 03-97

  4. A phase II study continuing into a randomized phase III study comparison of safety, feasibility and efficacy of: dose dense and tailored and dose escalated epirubicin + cyclophosphamide followed by docetaxel (dEC→T) or dose dense epirubicin + cyclophosphamide followed by docetaxel (EC→T) or docetaxel + doxorubicin + cyclophosphamide (TAC) in lymph node positive breast cancer patients.

Summary

  • Closed in March 1998 (opened on 1 March 1994)
  • Target accrual: 500 patients

Objectives

  • To compare disease-free survival of high-risk breast cancer patients treated with either high-dose chemotherapy + autologous stem cell transplantation or dose-escalated chemotherapy (CEC) both as adjuvant treatment.
  • To compare survival, safety, dose-intensity and total dose between the two treatment arms.
  • To assess quality of life.

Scheme

Update

  • Study closed in March 1998.
  • 525 patients randomized.
  • Reported in The Lancet 2000.
  • New update 2003.
  • Final update 2008.

Summary

  • The study was open from February 2001 to August 2003. 1535 patients received the first course of standard FEC, accrual completed.
  • 1052 patients were randomized.

Objectives

  • To study whether retrospective observations indicating suboptimal effect of CT in patients not experiencing toxicity can be confirmed in a prospective study.
  • To study whether dose-escalation in patients not experiencing leukopenia improves prognosis.

Scheme

First cycle of CEF-60:

  • If WBG GR III/IV: continue with 6 cycles of CEF-60/reduced dose
  • If WBG GR 0–II: randomize to 6 cycles of CEF-60/escalated CEF

Update

  • First analysis based on event rate 2007/2008.

HABITS – Hormonal replacement therapy after breast cancer diagnosis – is it safe?

Summary

  • Opened in 1998, closed in December 2003 for safety reasons
  • Target accrual: 1300 patients

Objectives

  • To investigate in women with radically treated in situ, stage I or early stage II breast cancer if the use of hormone replacement therapy (HRT for menopausal symptoms) is safe concerning risk of breast cancer recurrence.
  • To look at quality of life and risk of breast cancer death.

Scheme

Update

  • At the end of accrual 434 women were randomized. After a medium follow-up of 2.1 years, 26 women in the HRT group and seven in the non-HRT group had a new breast cancer event, corresponding to a relative hazard for HRT treatment of 3.5 (95% confidence interval 1.5–8.1). During 2005 and 2006 a new monitoring round was completed and new analyses presented during autumn 2006.

  • Randomized phase III 2-armed study: 900 patients

Objectives

  • For the phase II part: evaluate safety and feasibility in the three treatment arms.
  • Evaluate the dose intensity in the three treatment arms.

For the Phase III Part:

Primary Objective

  • Compare breast cancer recurrence-free survival (BCRFS), in the dtEC→dtT (tailored doses) arm compared with the EC→T (fixed doses) arm.

Secondary Objectives

  • Compare distant disease free survival (DDFS).
  • Compare event-free survival (breast cancer relapse, contralateral breast cancer, other malignancies).
  • Compare overall survival (OS).

Additional aims/biological markers.

Scheme

Update
