RESUMEN
<p><b>OBJECTIVE</b>To explore the role of laparoscopic sentinel lymph node(SLN) detection with carbon nanoparticles tracer in cervical carcinoma.</p><p><b>METHODS</b>Totally 21 patients with confirmed early cervical cancer were enrolled in this study.Before laparoscopic extended hysterectomy and pelvic lymphadenoetomy(and para-aortic lymphadenoectomy) , they were injected with carbon nanoparticles suspension injection tracer from cervical neck before surgery. The black-staining lymph nodes were cut as SLN under the laparoscope for routine pathological examination.</p><p><b>RESULTS</b>Of these 21 patients, at least one SLN was successfully detected in 20 patients(95.24%) , and a total of 158 SLNs were detected.The conventional pathology results suggested that 5 patients(23.81%) had positive lymph nodes(n=16, including 14 in 4 patients) . The new approach showed a sensitivity of 80.0%(4/5) , accuracy of 100.0%(20/20) , and negative predictive value of 100.0%(16/16) for SLN detection.</p><p><b>CONCLUSION</b>Laparoscopic SLN detection with carbon nanoparticles tracer is a relative safe and sensitive method for in cervical carcinoma.</p>
