The prognostic value of the presence of pelvic and/or para-aortic lymph node metastases in cervical cancer patients; the influence of the new FIGO classification (stage IIIC).

Introduction. One of the major changes in the revised (2018) FIGO-staging system is the addition of stage IIIC to the previously used 2009 system. We evaluated the prognostic value of positive pelvic and/or para-aortic lymph nodes in patients with cervical cancer.Methods. A nationwide retrospective cohort study was performed by analyzing data from the Netherlands Cancer Registry. All patients newly diagnosed with stage IB-IVA between 2005 and 2018 were identified. Three-year, 5-year and 15-year overall survival (OS) rates were estimated with the Kaplan-Meier method.Results. Of the included 6082 patients, 1740 patients (29%) had pelvic and/or para-aortic lymph node metas-tases. For patients with FIGO 2009 stage IB-IB1-IIA-IIA1 and stage IB2-IIA2-IIB with pelvic and/or para-aortic lymph node metastases the OS was significantly different (p < 0.001 and p = 0.009), with a 5-year OS of 77% and 67%, compared with 92% and 74% for women without lymph node metastases. For FIGO 2009 stage IIIA-IIIB-IVA with and without lymph node metastases, survival rates are not significantly different (p = 0.064). For FIGO 2018 stage IIIC the 3y-OS, 5y-OS and 15-year OS are 72%, 65% and 59% respectively. Survival rates of IIIC diagnosed based on imaging (IIICr) are significantly impaired compared to stage IIIC diagnosed based on pathology (IIICp) (p < 0.001).Conclusion. Patients with FIGO 2009 stage IB-IIB cervical cancer with pelvic and/or para-aortic lymph node metastases have significantly impaired survival compared to patients without metastases. Survival rates of patients with FIGO 2009 stage IIIA-IVA are not affected by lymph node metastases.(c) 2023 Published by Elsevier Inc

Salvage surgery for patients with residual disease after chemoradiation therapy for locally advanced cervical cancer: A systematic review on indication, complications, and survival

INTRODUCTION: Standard treatment for locally advanced cervical cancer is chemoradiation therapy. Treatment with chemoradiation therapy harbors a risk of local residual disease, which can be curatively treated with salvage surgery, but the risk of complications following surgical procedures in radiated tissue is not negligible. The presence of residual disease can be radiologically and/or histologically diagnosed. The objective of this study is to describe studies that report on salvage surgery for patients with locally advanced cervical cancer after primary treatment with chemoradiation therapy. Therefore, we assessed the method of determining the presence of residual disease, the risk of complications, and the survival rate after salvage surgery. MATERIAL AND METHODS: PubMed, EMBASE, and the Cochrane database were searched from inception up to 6 March 2020. Titles and abstracts were independently assessed by two researchers. Studies were eligible for inclusion when patients had locally advanced cervical cancer with radiologically suspected or histologically confirmed residual disease after chemoradiation therapy, diagnosed with a CT, MRI, or PET-CT scan, or biopsy. Information on complications after salvage surgery and survival outcomes had to be reported. Methodological quality of the articles was independently assessed by two researchers with the Newcastle-Ottawa scale. RESULTS: Of the 2963 screened articles, six studies were included, representing 220 women. A total of 175 patients were treated with salvage surgery, of whom 27%-100% had residual disease on the surgery specimen. Of the 161 patients treated with salvage surgery based on positive biopsy results, 72%-100% showed residual disease on the surgery specimen. Of the 44 patients treated with salvage surgery based on suspected residual disease on radiology, 27%-48% showed residual disease on the salvage surgery specimen. A total of 105 complications were registered in 175 patients treated with salvage surgery. The overall survival rate after salvage surgery was 69% (mean follow-up period of 24.9 months). CONCLUSIONS: It is necessary to confirm residual disease by biopsy before performing salvage surgery in patients with locally advanced cervical cancer primarily treated with chemoradiation therapy. Salvage surgery only based on radiologically suspected residual disease should be avoided to prevent unnecessary surgery and complications
