Objective: The recently updated World Health Organization classification divides endocervical adenocarcinomas (ADCs) into human papillomavirus (HPV)-associated (HPVA) and HPV-independent (HPVI) ADCs. This study aimed to investigate the differences in the clinical features and treatment outcomes between patients with HPVA and HPVI.
Methods: We retrospectively reviewed the electronic medical records and pathology slides of 123 patients with endocervical ADC who underwent radical hysterectomy and adjuvant radiation therapy. Tumor characteristics, patterns of failure, and survival outcomes were compared between HPVA and HPVI ADCs.
Results: Eighty-one (65.9%) and 42 (34.1%) patients were diagnosed with HPVA and HPVI ADCs, respectively. HPVI ADC showed more frequent positive vaginal resection margin (VRM) and peritoneal seeding than HPVA ADC. After a median follow-up of 58.1 months, local recurrence and distant metastasis were more frequently observed in HPVI ADC than in HPVA ADC. Both local recurrence-free survival (77.3% vs. 91.8%) and distant metastasis-free survival (50.1% vs. 73.7%) rates of HPVI ADC were lower than those of HPVA ADC. Disease-free survival was not significantly different between HPVI and HPVA ADCs.
Conclusion: We demonstrated that HPVI ADC exhibited higher rates of VRM involvement and peritoneal seeding than those of HPVA ADC, resulting in higher rates of local recurrence and distant metastasis. Further studies with larger populations are warranted to explore optimal treatment strategies based on the histological subtypes of endocervical ADC.
