Summary
Sentinel lymph node (SLN) detection using a gamma probe is feasible for early-stage cervical cancer. This method accurately identified SLNs, showing promise for guiding treatment in gynecologic oncology.
Area of Science:
- Gynecologic Oncology
- Nuclear Medicine
- Surgical Pathology
Background:
- Sentinel lymph node (SLN) biopsy is crucial for staging gynecologic cancers.
- Accurate SLN detection is essential for precise surgical planning and treatment in cervical cancer.
Purpose of the Study:
- To evaluate the diagnostic accuracy and feasibility of sentinel lymph node detection using a gamma probe in patients with FIGO IB cervical cancer.
- To assess the utility of technetium(99)m-labelled nanocolloid for SLN identification in cervical cancer.
Main Methods:
- 14 patients with FIGO IB cervical cancer underwent SLN detection prior to radical hysterectomy.
- Technetium(99)m-labelled nanocolloid was injected into the cervix, followed by gamma camera imaging and intraoperative handheld gamma probe detection.
- SLNs were resected and analyzed histopathologically and immunohistochemically.
Main Results:
- Scintigraphy showed focal uptake in 13 out of 14 patients.
- A total of 26 SLNs were detected intraoperatively using the gamma probe.
- Only one patient had a histologically positive SLN, with no false-negative results observed.
Conclusions:
- Sentinel lymph node identification is feasible in cervical cancer using preoperative technetium(99)m-labelled nanocolloid and gamma probe detection.
- This technique shows potential for improving staging and therapy planning in cervical cancer.
- Further studies with larger patient cohorts are needed to confirm these findings and establish SLN detection in routine clinical practice.
