Abstract
Background
To evaluate the feasibility after 5 years experience of a laparoscopic sentinel node (SN) procedure with combined radioisotopic and patent blue labeling in patients with cervical cancer.
Methods
Sixty-seven patients (median age 48.9 years) with cervical cancer underwent a laparoscopic SN procedure using an endoscopic gamma probe, after both radioactive and patent blue injections. After the procedure, all the patients underwent complete laparoscopic pelvic/para-aortic lymphadenectomy.
Results
At least one SN was identified in 57 patients (85.1%). According to the Stage, the SN identification rate was 91.2% in early-stage cervical cancer and 78.5% in locally advanced cervical cancer. The mean number of SN was 2.3 per patient (range 1–5). A total of 129 SNs were removed. Lymph node metastasis involvement was identified in the 20 SNs (15.5%) from 14 patients (24.6%). Nine of the 14 patients had at least one macrometastases, three patients presented micrometastases in H&S, and two patients presented isolated single cells. Six patients presented a pelvic non-SN involvement including two patients whose SNs were uninvolved. The false-negative SNs rate was 12.5% (two patients out of 16). Both patients have locally advanced cervical cancer.
Conclusion
This study confirms that laparoscopic SN detection with a combination of radiocolloid and patent blue is accurate in patients with early cervical cancer to assess pelvic lymph node status.
