Objective:
Peritoneal involvement may be overlooked in patients with locally advanced cervical cancer (LACC). This may lead to underestimation of prognosis and to undertreatment limited to locoregional disease locations. However, staging laparoscopy in LACC is not routinely performed. The primary aim of this study was to determine the proportion of peritoneal metastasis by laparoscopy and the factors associated with peritoneal metastasis in patients with LACC. Secondary aims were to evaluate the performance of staging imaging in detecting peritoneal disease and the prognosis of patients with peritoneal metastasis.
Methods:
Retrospective single-institution study including consecutive patients with newly diagnosed LACC (FIGO 2018 stage IB3 and IIA2-IVA) between 06/2015 and 06/2020. All women underwent PET/CT scan, MRI scan and diagnostic laparoscopy at the time of examination under anesthesia (EUA), as part of cervical cancer staging. Peritoneal metastasis was histologically confirmed in all cases.
Results:
251 patients were included. 33 (13.2 %) had peritoneal metastasis. The treatment plan was changed for 28/33 (84.8 %) patients with peritoneal metastasis (11.1 % of the entire LACC cohort). Multivariate analysis demonstrated that grade 3 (OR:1.572, 95%CI:1.021-2.419; p = 0.040) and AJCC stage T3-4 (OR:3.435, 95%CI:1.482-7.960; p = 0.004) were variables associated with increased risk of peritoneal metastasis. Sensitivity of PET/CT-scan and MRI-scan in detecting peritoneal metastasis was 4.5 % (95%CI:0.1-22.8) and 13.8 % (95%CI:3.9-31.7), respectively. Peritoneal metastasis was independently associated with worse PFS and OS (HR:3.008, 95%CI:1.779-5.087, p < 0.001 and HR:4.078, 95%CI:2.232-7.451; p < 0.001, respectively).
Conclusion:
LACC patients with grade 3 histology and/or AJCC stage T3-4 had high-risk of peritoneal metastasis and diagnostic laparoscopy might be considered as part of cervical cancer staging in these patients. Peritoneal metastasis was an independent factor associated with worse PFS and OS.
