Hypothesis
Can ultrasonographic examination of axillary lymph nodes combined with fine-needle aspiration improve preoperative staging in breast cancer patients?
Conclusion
Ultrasound-guided fine-needle aspiration can reliably predict the presence of metastases in axillary lymph nodes, potentially allowing for more appropriate surgical treatment.
Supporting Evidence
- Ultrasound-guided FNAC showed high sensitivity and absolute specificity in diagnosing lymph node metastases.
- 49 out of 88 metastatic lymph nodes were correctly identified by FNAC.
- The combination of ultrasound and FNAC improved diagnostic accuracy compared to ultrasound alone.
- Only 16% of cytological diagnoses were false negatives, indicating high reliability of the method.
- Immunocytochemistry increased the sensitivity of routine cytological diagnosis.
Takeaway
Doctors can use a special ultrasound and needle technique to check if breast cancer has spread to nearby lymph nodes, which helps them decide the best treatment.
Methodology
The study involved 298 breast cancer patients who underwent ultrasound examination and fine-needle aspiration of axillary lymph nodes before surgery.
Potential Biases
There may be risks of bias related to the selection of patients and the interpretation of cytological results.
Limitations
The study may have limitations related to the skill of the operators performing the procedures and the potential for false negatives.
Participant Demographics
The study included 298 patients with breast carcinomas, with a majority being invasive carcinomas.
