Article Abstract
Objective: To evaluate the relationship between the clearance rate of technetium-99m methoxyisobutylisonitrile ((99m)Tc-MIBI) in scintimammography and the efficacy of neoadjuvant chemotherapy (NCT) of patients with operable breast cancer.
Methods: Seventy-eight patients with breast cancer underwent (99m)Tc-MIBI scintimammography at pre-NCT. And static planar images were taken at 10 min and 180 min post-scintimammography. The clearance rate was calculated in each patient. And the efficacy of NCT was evaluated after 2 cycles.
Results: The clearance rates of patients with a poor or good efficacy of chemotherapy were 24.21% ± 6.38% (n = 14) and 14.13% ± 5.98% (n = 64) respectively. There was significant difference between two groups. And a significant correlation was observed between the efficacy of chemotherapy and the clearance rate of (99m)Tc-MIBI (r = -0.539, P < 0.001).
Conclusion: The scintimammography of (99m)Tc-MIBI may be employed to evaluate the efficacy of NCT.
Purpose: To compare the potential application of (99m)Tc-3P-Arg-Gly-Asp ((99m)Tc-3P4-RGD2) scintimammography (SMM) and (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) SMM for the differentiation of malignant from benign breast lesions.
Method: Thirty-six patients with breast masses on physical examination and/or suspicious mammography results that required fine needle aspiration cytology biopsy (FNAB) were included in the study. (99m)Tc-3P4-RGD2 and (99m)Tc-MIBI SMM were performed with single photon emission computed tomography (SPECT) at 60 min and 20 min respectively after intravenous injection of 738 ± 86 MBq radiotracers on a separate day.
Purpose: To evaluate post-surgical tumor-metabolic regions outside of the computed tomography (CT)-defined volume for radiation therapy (RT) planning using functional imaging of scintimammography (SMG) ± single photon emission computerized tomography (SPECT) in breast cancer (BC) patients.
Methods: 62 operated high-risk BC females, mean age 50.45 years, underwent SMG±SPECT before RT planning.
Objective: To evaluate the relationship between the clearance rate of technetium-99m methoxyisobutylisonitrile ((99m)Tc-MIBI) in scintimammography and the efficacy of neoadjuvant chemotherapy (NCT) of patients with operable breast cancer.
Methods: Seventy-eight patients with breast cancer underwent (99m)Tc-MIBI scintimammography at pre-NCT. And static planar images were taken at 10 min and 180 min post-scintimammography.
Objective: To evaluate the accuracy of 99mTc-MIBI scintimammography (SMM) in differentiating malignant breast cancer from benign breast mass and in detecting axillary lymph node metastasis in comparison with mammography and ultrasonography.
Study Design: Comparative cross-sectional study.
Place And Duration Of Study: At the Karachi Institute of Radiotherapy and Nuclear Medicine (KIRAN), Karachi, from December 2006 to May 2007.
