摘要

Purpose

Neoadjuvant radiochemotherapy (NARCT) is an established standard of care in various tumor entities, promoting high response rates at commonly lower toxicities as compared to adjuvant approaches. This retrospective analysis was designed to investigate NARCT in early-stage high-risk cervical cancer.

Methods

Forty patients with early-stage high-risk cervical cancer (i.e., L1, V1, G3, N+, > 2/3 stromal invasion, > 4 cm tumor size, borderline resectability) were treated with NARCT prior to surgical resection. Downstagings based on clinical, imaging, and pathological responses were recorded. Survival rates were calculated according to Kaplan–Meier, and prognostic factors were analyzed with uni- and multivariable Cox regression analyses using SPSS software (v. 26; IBM Corp., Armonk, NY, USA).

Results

Both NARCT and subsequent tumor resection were feasible and conducted in 39 of 40 patients (95%). Early toxicity was moderate, with no grade 3 or higher toxicities following NARCT and surgery. NARCT yielded significant downstaging in all patients, and pathological complete remission (pCR) was achieved in 14 patients (36%). After 5 years, overall survival (OS), freedom from local progression (FFLP), and freedom from distant progression (FFDP) rates were 84.2%, 75.9%, and 73.1%, respectively. Late proctitis (grade 1 in 8%) and urinary cystitis (grade 1–3 in 35%) occurred at acceptable rates.

Conclusion

In resectable early-stage high-risk cervical cancer, NARCT is feasible and safe. Clinical, imaging, and pathological response rates are high. Impressive long-term survival and tumor control rates at modest toxicities encourage the initiation of a prospective and randomized trial.
