Abstract: To analyze concordance between preoperative lymphoscintigraphy and intraoperative lymphatic mapping (ILM) for sentinel lymph node identification using technetium 99m-labeled-dextran 500 (99m-Tc) and patent blue dye in patients with early cervical cancer undergoing radical hysterectomy and pelvic lymphadenectomy, as well as to evaluate sentinel lymph node (SLN) detection. Forty-seven patients underwent surgical treatment for cervical cancer. For SLN identification, 99m-Tc and blue patent were injected into the cervix on the eve and day of surgery, respectively. Preoperative pelvic lymphoscintigraphy was performed in all patients after 99m-Tc injection. Concordance between preoperative lymphoscintigraphy and ILM was evaluated. Of the 56 patients who underwent preoperative lymphoscintigraphy, 43 (81.13%) had at least one lymph node identified. Bilateral lymph nodes were identified in 21 (37.5%) patients. Sentinel lymph nodes detected on ILM had been previously found on preoperative lymphoscintigraphy in 66.7%, 67.2% and 0% in the right, left and central locations, respectively. In 14 patients (25%), only one lymph node was identified on preoperative lymphoscintigraphy, but more than one sentinel lymph node was detected on intraoperative mapping. In nine (16.1%) patients, lymphoscintigraphy showed only unilateral lymph nodes, but ILM identified bilateral sentinel lymph nodes. The combination of patent blue and radionuclide techniques produced excellent results for SLN detection in cervical cancer. Preoperative lymphoscintigraphy does not offer any advantage over ILM for SLN identification.
