This section provides current contact details and a summary of recent or ongoing clinical trials being coordinated by Spanish Breast Cancer Research Group (GEICAM). Clinical trials include: FAC versus CMF as adjuvant chemotherapy for operable breast cancer: a study by the GEICAM group.

GEICAM/9401High-dose DICEP chemotherapy versus observation in metastatic breast cancer patients with monotopic disease responding to induction chemotherapy with paclitaxel plus epirubicin. Phase III GEICAM trial. GEICAM/9601Vinorelbine infusion over 96 hours in heavily pre-treated patients with metastatic breast cancer: a cooperative study by the GEICAM group. GEICAM/9702Phase II trial of gemcitabine in combination with vinorelbine in patients with metastatic breast cancer resistant to anthracyclines. GEICAM/9704A phase II trial for evaluation of sequential doxorubicin and docetaxel as first-line treatment in metastatic breast cancer. GEICAM/9801A multicenter phase III randomized trial comparing docetaxel with doxorubicin and cyclophosphamide (TAC) versus 5-fluorouracil with doxorubicin and cyclophosphamide (FAC) as adjuvant treatment of operable breast cancer patients with negative axillary lymph nodes. TARGET 0 / GEICAM/9805A multicenter phase III randomized trial to compare the sequential and the concomitant administration of doxorubicin and docetaxel, as first-line chemotherapy treatment for metastatic breast disease. GEICAM/9903Docetaxel plus gemcitabine administered every other week as first-line treatment for metastatic breast cancer. GEICAM/9904Weekly docetaxel as neo-adjuvant treatment in stage II and III breast cancer.

GEICAM/9906An open, multicenter randomized phase IV trial for the administration of pamidronate to breast cancer patients with bone metastatic disease. GEICAM/2000-01A randomized phase III treatment to compare the administration of vinorelbine versus vinorelbine plus gemcitabine in patients with metastatic breast cancer previously treated with anthracyclines and taxanes. GEICAM/2000-04Maintenance phase III/IV study for the administration of Caelyx versus no treatment, after induction chemotherapy for metastatic breast cancer disease. GEICAM/2001-01A multicenter, cross-over, randomized trial with exemestane versus anastrozole as first-line hormonal treatment of postmenopausal women with metastatic breast cancer disease and positive hormone receptors. GEICAM/2001-03A multicenter, open-label randomized phase III trial for the administration of zoledronate to patients with advanced breast cancer disease and non-symptomatic bone metastasis. GEICAM/2001-05A multicenter phase II trial to evaluate the administration of gemcitabine with doxorubicin and paclitaxel (GAT) as neo-adjuvant treatment of stage III disease breast cancer patients. GEICAM/2002–01A phase II trial to evaluate the administration of doxorubicin with cyclophosphamide (AC) followed by weekly docetaxel (T) as neo-adjuvant treatment of stage II disease breast cancer patients. GEICAM/2002–03A multicenter, open-label, randomized phase III trial comparing six courses of FAC (fluorouracil, doxorubicin, cyclophosphamide) with four courses of FAC followed by 8-weekly administrations of Taxol in the adjuvant treatment of node-negative patients with operable breast cancer. GEICAM/2003–02A multicenter, open-label, randomized phase III trial comparing epirubicin plus cyclophosphamide (EC) followed by docetaxel (T) with epirubicin plus docetaxel (ET) followed by capecitabine (X) in the adjuvant treatment of node-positive patients with operable breast cancer. GEICAM/2003–10Open-label, no randomized, phases I–II of the treatment with Myocet/Taxotere/Herceptin as primary antineoplasic treatment in newly diagnosed breast cancer patients with HER2neu overexpression. GEICAM/2003–03Phase IV.II clinical trial with the combination of pegylated liposomal doxorubicin, cyclophosphamide and trastuzumab in patients with metastatic breast cancer with overexpression HER2neu. GEICAM/2004–05Randomized clinical trial to compare the benefit of adding trastuzumab to the combination of capecitabine plus vinorelbine as second-line treatment for patients with locally advanced non-operable breast cancer or metastatic breast cancer with overexpression of HER2, who have progressed to a previous line of treatment for metastatic disease that included trastuzumab in combination with taxanes. GEICAM/2004–06Phase IV.II clinical trial, multicenter, for administration of capecitabine concomitant to radiotherapy in patients with locally advanced breast cancer and HER2neu negatives. GEICAM/2005–01Phase IV.III, multicenter, open, randomized treatment study to evaluate the efficacy of maintenance therapy with capecitabine after standard chemotherapy with anthracyclines in patients with metastatic breast cancer.

AbstractWe used 3D printed-breast surgical guides (3DP-BSG) to designate the original tumor area from the pre-treatment magnetic resonance imaging (MRI) during breast-conserving surgery (BCS) in breast cancer patients who received neoadjuvant systemic therapy (NST). Targeting the original tumor area in such patients using conventional localization techniques is difficult. For precise BCS, a method that marks the tumor area found on MRI directly to the breast is needed. In this prospective study, patients were enrolled for BCS after receiving NST. Partial resection was performed using a prone/supine MRI-based 3DP-BSG. Frozen biopsies were analyzed to confirm clear tumor margins. The tumor characteristics, pathologic results, resection margins, and the distance between the tumor and margin were analyzed. Thirty-nine patients were enrolled with 3DP-BSG for BCS. The median nearest distance between the tumor and the resection margin was 3.9 cm (range 1.2–7.8 cm). Frozen sections showed positive margins in 4/39 (10.3%) patients. Three had invasive cancers, and one had carcinoma in situ; all underwent additional resection. Final pathology revealed clear margins. After 3-year surveillance, 3/39 patients had recurrent breast cancer. With 3DP-BSG for BCS in breast cancer patients receiving NST, the original tumor area can be identified and marked directly on the breast, which is useful for surgery. Trial Registration: Clinical Research Information Service (CRIS) Identifier Number: KCT0002272. First registration number and date: No. 1 (27/04/2016).
