Purpose:
Minimally invasive radical hysterectomy has been associated with increased recurrence of disease and worse survival compared with open radical hysterectomy for early-stage cervical cancer. We evaluated patterns of recurrence and histopathologic risk factors in patients who underwent robotic radical hysterectomy (RRH).
Methods:
Patients who underwent RRH (4/2007-12/2018) were evaluated for specific locations of recurrent disease, disease-free survival, overall survival (OS), and histopathologic risk factors for recurrence. Inclusion criteria were follow-up ≥ 1 year, histology with adenocarcinoma, adenosquamous, or squamous carcinoma and clinical stage IA2 to IB ≤ 4-cm tumor size cervical cancers (FIGO-2018).
Results:
A total of 140 patients underwent RRH and 112 met criteria. Median tumor size was 2.1 cm [interquartile range (IQR): 1.1-3.3]. Median follow-up was 61 months (IQR: 36-102). Fifty (45%) patients underwent adjuvant radiation ± cisplatin with either Sedlis' or Peters' risk factors. There were 11 (9.8%) recurrences with median disease-free survival of 12 (IQR 8.5) months. All patients with recurrence had measured tumor size ≥ 2 cm (median tumor size 3-cm (IQR: 2.6-4.0). Tumor size > 2 cm was associated with Sedlis' intermediate-risk factors (p < 0.05) and Peters' high-risk factors (p < 0.05). Forty patients underwent preoperative conization, and two (5%) with deep positive margins in lesions > 2 cm recurred. Five (4.5%) of patients had carcinomatosis representing 45% of all recurrences. Carcinomatosis was associated with reduced OS compared with other recurrence patterns (22 months vs. 7.8 years, p < 0.05).
Conclusions:
Carcinomatosis was observed in early-stage cervical cancers treated with RRH and was associated with reduced OS. All recurrences were associated with lesions ≥ 2 cm, and no recurrences were identified with negative conization margins.
