Objective:

To investigate the correlation between tumor/breast volume ratios measured by magnetic resonance imaging (MRI) and the surgical methods of breast cancer patients.

Methods:

Randomly collected 30 patients with breast conserving surgery as the study group and 30 patients undergoing modified radical mastectomy as the control group. There were 58 cases of si

ngle breast cancer and 2 cases of multiple breast cancer. All patients were selected for breast conserving or modified radical resection after a combination of routine examination

surgeon evaluation

and patient wishes. In each of the two groups

20 patients did not receive neoadjuvant chemotherapy before surgery and 10 patients received neoadjuvant chemotherapy before surgery. All patients underwent MRI examination before operation. Their tumor/mammary volume ratio was calculated retrospectively

and the difference of tumor/breast volume ratio was compared between the two groups.

Results:

In the study group

only 1 patient (3.33%) had positive incisal margin and underwent augmentation mass resection. The mean tumor/breast volume ratio of all patients in the study group and the control group was 4.35% and 9.65% (

P

=0.003). The average tumor/breast volume ratio of the two groups without preoperative neoadjuvant chemotherapy was 5.32% and 10.18% (

P

=0.027). The average tumor/breast volume ratios of preoperative neoadjuvant chemotherapy patients in the two groups were respectively 2.43% and 8.58% (

P

=0.07).

Conclusion:

The tumor/breast volume ratio measured from breast MRI data is related to the selection of surgical methods for newly diagnosed breastcancer patients

and it is an effective evaluation method to determine the optimal operation type of newly diagnosed breast cancer patients. However

the selection of surgical methods for patients undergoing neoadjuvant chemotherapy before surgery has not shown effective application value. In daily work

comprehensive assessment should be based on actual conditions.
