Summary: | Objective: For oncologic safety, vaginal radical trachelectomy is generally performed only in patients with cervical cancers smaller than 2 cm. However, because inclusion criteria for abdominal trachelectomy are controversial, we evaluated the safety of abdominal trachelectomy for cervical cancers ≥2 cm.
Methods: We began performing abdominal trachelectomies at our institution in 2005, primarily for squamous cell carcinoma ≤3 cm or adenocarcinoma/adenosquamous carcinoma ≤2 cm. If a positive sentinel lymph node or cervical margin was diagnosed intraoperatively by frozen section, the trachelectomy was converted to a hysterectomy. Medical records of these patients were reviewed retrospectively. Patients who had undergone simple abdominal trachelectomy were excluded from this study.
Results: We attempted trachelectomy in 212 patients. Among the 135 patients with tumors <2 cm, trachelectomy was successful in 120, one of whom developed recurrence and none of whom died of their disease. Among 77 patients with tumors ≥2 cm, trachelectomy was successful in 62, 2 of whom developed recurrence and 1 of whom died of her disease. The overall relapse rate after trachelectomy was 1.6% (0.8% in <2 cm group and 3.2% in ≥2 cm group), and the mortality rate was 0.5% (0% in <2 cm group and 1.6% in ≥2 cm group). Recurrence-free survival (p=0.303) and overall survival (p=0.193) did not differ significantly between the <2 cm and ≥2 cm groups.
Conclusions: Abdominal trachelectomy with intraoperative frozen sections of sentinel lymph nodes and cervical margins is oncologically safe, even in patients with tumors ≥2 cm. |
