This collection contains longitudinal DCE MRI studies of 64 patients undergoing neoadjuvant chemotherapy (NACT) for invasive breast cancer. 

Patient population

This pilot study to investigate the use of serial DCE MRI examinations during neoadjuvant chemotherapy for invasive breast cancer recruited 68 patients with stage II or III locally advanced breast cancer enrolled between 1995 and 2002 in an institutional review board (IRB)-approved research protocol.  All patients gave written informed consent to participate. All patients had confirmed breast cancer diagnoses based on histopathology of biopsy or surgical excision, and none had prior treatment with chemotherapy, surgery or radiation. All patients received pre-operative chemotherapy with four cycles of adriamycin-cytoxan administered every three weeks. A subset of 17 patients received additional weekly treatment with taxane after the Anthracycline regimen was completed. Three DCE-MRI scans were scheduled for all patients: MRI1 before treatment; MRI2 after one cycle of chemotherapy; MRI3 after completion of Anthracycline treatment and before surgery or further treatment. Subjects receiving Taxane were scheduled for an additional exam, MRI4, after completion of all chemotherapy treatment and before surgery.

Figure 1. UCSF Pilot NACT study schema. Only an N=17 subset of patients received Taxane and MRI4 as a result of changes in standard of care during the course of the study. Note: Not all patients received core biopsies as indicated in this schema.

Exclusions: Of the 68 patients, four have been excluded from this collection: one did not undergo surgery, one did not have a pre-surgery time-point MRI, one was rejected due to unanalyzable MR images, and one had metastatic disease prior to the completion of treatment. None of the excluded patients were from the 17 subject Taxane group. Three patients are included here but may be excluded at researchers' discretion due to treatment anomalies: a) Two subjects in the Taxane group (UCSF_BR_30 and UCSF_BR_53) did not complete the Taxane treatment, but were moved directly to surgery early and did not have the final MRI4 examination, and b) Patient UCSF_BR_27 declined standard-of-care post-surgery radiation and hormonal treatments. These cases are noted in the accompanying clinical information workbook.

Endpoint data: Recurrence-free survival (RFS) was assessed for each patient at 6-month or 1-year intervals following surgery. For patients that recurred, length of RFS was defined as the time from initial surgery to either local or distant recurrence. Other clinical and endpoint data includes patient age, lesion characteristics including pretreatment tumor size, histologic type, pathologic size, tumor subtype, and lymph node involvement. These data are included as supplemental information for the collection in the accompanying clinical information workbook.

MRI acquisition

Breast MRI was acquired on a 1.5-T scanner (Signa, GE Healthcare, Milwaukee, WI) using a bilateral phased array breast coil. The MR imaging protocol included a 3D localizer and a unilateral sagittal DCE acquisition. The DCE acquisition utilized a high spatial resolution, low temporal resolution, T1-weighted, fat-suppressed 3D fast gradient-recalled echo sequence developed for pre-surgical staging (TR/TE 8/4.2; flip angle 20 degrees; field of view 18-20 cm; acquisition matrix 256 x 192 x 60, section thickness 2 mm; spatial resolution 0.7 x 0.94 x 2.0 mm3). A minimum of three time points were acquired during each contrast-enhanced MRI protocol: a pre-contrast scan (t0), followed by 2 consecutive post-contrast time points: early (t1) and late (t2) phases. The gadopentetate dimeglumine contrast agent (Magnevist, Bayer HealthCare, Berlin, Germany), was injected at a dose of 0.1 mmol/kg of body weight (injection rate = 1.2 mL per second) followed by a 10 mL saline flush, with injection starting coincident with the start of the early t 1  phase acquisition. Imaging time was approximately 5 minutes per acquisition, resulting in effective early and late post-contrast time points of 2.5 minutes and 7.5 minutes from the start of the contrast injection, respectively, using standard k-space sampling. Fat suppression was performed using a frequency-selective inversion recovery preparatory pulse.

Included image data

Original and time-of-scan derived images.

Original DCE images are contained in a single series for each study. For the majority of studies (174 of 198) this series contains only the 3 time-points described above. 12 studies have 1 additional post-contrast acquisition for a total of 4 phases, while 2 studies, UCSF_BR_36, visit 1, and UCSF_BR_42, visit 1, have 4 and 6 post-injection phases respectively.

NOTE: Study UCSF_BR_18, Visit 1, has two pre-contrast acquisitions and two post-contrast phases. Use of the 2nd pre-contrast phase for time-point t0 is recommended. All other studies have a single pre-contrast phase.

Other original image series present in the collection include 3-plane scout images for each study, and for some studies T2 weighted images and diffusion weighted images. In addition, some studies may contain derived images from the DCE series including subtraction images and projection images.

Tumor volumetric analysis images.

The primary predictor variable for the original study, functional tumor volume (FTV), was measured from contrast-enhanced images using the signal enhancement ratio (SER) method. Four derived series per study from this analysis are included in this collection:

  1. SER true values range from 0.0 to 3.0. These are scaled by 1000 in order to store in integer format. DICOM viewers utilizing the rescale-slope field (0028,1053) will display the true SER values.
  2. The PE early segmentation is based on both the breast tissue segmentation (background level threshold, see next footnote) and an early percent enhancement threshold of 70%.
  3. The breast tissue segmentation is based on an intensity threshold applied to the pre-contrast image. Threshold was set to 60% of the 95% percentile intensity within the tumor region volume-of-interest. Coordinates of the VOI are stored in all derived DICOM images using private fields (0117, 10a1) and (0117, 10a2) for the starting and ending voxel coordinates respectively.
