Functional MRI in Predicting Response to Chemotherapy (MRI)
Superadded Value of Functional MRI Techniques in Evaluation of Malignant Breast Cancers Following Clips Guided Neoadjuvant Chemotherapeutic Series
Study Overview
Detailed Description
patient selection:
Selection of patients diagnosed with of biopsy proven breast cancer (BIRAD VI ) :
• Inclusion criteria: patient in different age groups with local advanced breast cancer who are eligible for neoadjuvant chemotherapy and breast conservative surgery and in need for clip placement for tumor localization
Breast cancer (BC) is the second most common cancer in the world and by far the most frequent cancer among women. In Egypt the incidence rate of breast cancer is 29.9/100,000 population in the age group of 30-34 years with the highest population among young women. (1).
Management of breast cancer depends upon its stage. Early stages (stage I) with small sized breast masses undergo breast conservative surgery (BCS) while locally advanced breast masses (stage II and III) may require Preoperative administration of Neoadjuvant chemotherapy (NAC) to decrease the tumor burden allowing for BCS instead of mastectomy with no significant difference in disease-free survival for patients receiving breast conservation in comparison to mastectomy.(2, 3)
Patients who achieve a pathologic complete response (pCR; defined as no residual tumor or a minimal residual tumor on histologic analysis) post NAC demonstrate significantly longer disease-free and overall survival rates(4).
Predicting whether a patient will respond or not to the given chemotherapy would allow an early change in chemotherapy regime or early resort to surgery saving patients from potential toxic effects of chemotherapy and provide a greater chance of achieving a pCR.(5, 6)
Imaging is more accurate than clinical examination in monitoring response to therapy. Different imaging modalities including Digital mammography, ultrasound and MRI have been incorporated in predicting tumoral response to NAC however the MRI has the upper hand due to its higher sensitivity.(3)
Assessing tumoral response to chemotherapy based on observing the regression in the tumor size is widely accepted(7). However, changes in tumor microvasculature, cell density can predate tumoral size change therefore the use of Functional MRI techniques as diffusion-weighted MRI (DWI), MR spectroscopy (MRS) or Dynamic Contrast-Enhanced MRI (DCE) can be used to quantify these early histopathological changes in the tumor.(8)
DCE MRI was reported by multiple studies as the optimal imaging tool to determine disease response, with an accuracy of approximately 91% however there is no established cutoff of enhancement determining partial versus complete response.In three recent studies, the routine use of DWI allowed early differentiation between responders and non-responders by at least a 20% increase in apparent diffusion coefficient, thereby allowing for tailoring of chemotherapy. Also it was reported that the addition of DWI to DCE MRI resulted in improved diagnostic performance in predicting residual disease after chemotherapy.(3) 80% to 90% of patients receiving NAC have a significant response rate of the primary tumor to neoadjuvant chemotherapy. However, this significant response complicates the surgical excision because it is difficult to verify accurate localization of the site of the previous tumor. Therefore the use of a radiopaque marker placed in the tumor bed before administrating chemotherapy has been reported as a safe and inexpensive technique that allows later on for wire guided localization of the tumor bed before surgical resection (9).
In a report on patients who underwent clip placement and preoperative chemotherapy indicated that preoperative wire localization of the tumor bed would have been impossible in 35.7% of patients and difficult in 21.4% of patients without the aid of the clip. Dash et al. concluded that the clip placement was valuable in 57% of patients at the time of preoperative needle localization(10). Edeiken and colleagues reported a similar experience with ultrasound-guided implantation of metallic markers. The markers reportedly were the only remaining evidence of the original tumor site in (47%) of patients.
In a study conducted in M. D. Anderson Cancer Center, Houston, Texas in 2007 aiming to determine whether patients with breast cancer who received breast-conservation therapy after neoadjuvant chemotherapy had improved outcomes if radiopaque clips were placed to mark the primary tumor. The study concluded that the omission of tumor bed clips was associated with a hazard ratio of 3.69 for increased local recurrence compared with patients who did have radiopaque clip placement (P =.083;95% confidence interval , 0.84-16.16).(9)
