| 背景及目的: 乳腺癌是女性最常见的恶性肿瘤,准确评估肿瘤大小及范围对于选择合适的外科治疗方法至关重要,高估或者低估肿瘤大小均能带来不良影响,本研究拟探讨磁共振和超声在评估早期乳腺癌肿瘤大小和范围的精确性。 |
| 英文摘要: |
| Objective: Breast cancer is the most frequently diagnosed cancer in women. Accurate evaluation of the
size and extent of the tumor is crucial in selecting a suitable surgical method for patients with breast cancer.
Both overestimation and underestimation have important adverse effects on patient care. This study aimed
to evaluate the accuracy of breast magnetic resonance imaging (MRI) and ultrasound (US) examination for
measuring the size and extent of early-stage breast neoplasms.
Methods: The longest diameter of breast tumors in patients with T1–2N0–1M0 invasive breast cancer preparing
for breast-conserving surgery (BCS) was measured preoperatively by using both MRI and US and their
accuracy was compared with that of postoperative pathologic examination. If the diameter difference was
within 2 mm, it was considered to be consistent with pathologic examination.
Results: A total of 36 patients were imaged using both MRI and US. The mean longest diameter of the tumors
on MRI, US, and postoperative pathologic examination was 20.86 mm ± 4.09 mm (range: 11–27 mm),
16.14 mm ± 4.91 mm (range: 6–26 mm), and 18.36 mm ± 3.88 mm (range: 9–24 mm). US examination
underestimated the size of the tumor compared to that determined using pathologic examination (t = 3.49,
P < 0.01), while MRI overestimated it (t = ?6.35, P < 0.01). The linear correlation coefficients between the
image measurements and pathologic tumor size were r = 0.826 (P < 0.01) for MRI and r = 0.645 (P < 0.01)
for US. The rate of consistency of MRI and US compared to that with pathologic examination was 88.89%
and 80.65%, respectively, and there was no statistically significant difference between them (χ2 = 0.80,
P > 0.05).
Conclusion: MRI and US are both effective methods to assess the size of breast tumors, and they maintain
good consistency with pathologic examination. MRI has a better correlation with pathology. However,
we should be careful about the risk of inaccurate size estimation. |
