Introduction/Background Despite being a disease of mainly older women, little is known about the clinical management of older women with vulvar squamous cell carcinoma (VSCC). We evaluated their daily clinical management compared with younger women, and established the prevalence of comorbidities and its impact on overall survival (OS).

Methodology All Dutch women diagnosed with VSCC from 2015 to 2020 (n=2,249) were selected from the Netherlands Cancer Registry. Women aged ≥80 years (n=632, 28%) were defined as ’older’ patients, women <80 years were considered as ’younger’. Chi-square tests were performed to evaluate differences in treatment by age group and comorbidities. Differences in OS were evaluated using Kaplan-Meier Curves and log-rank test.

Results The vast majority of both older (91%) and younger (99%) patients with FIGO IA VSCC received surgical treatment of the vulva. Older FIGO IB-IV VSCC patients were less likely to undergo groin surgery than younger patients (50% vs. 84%, p<0.01). Performance of surgical treatment of the vulva and groin(s) was not associated with the number of comorbidities in older patients (p=0.67 and p=0.69). Older patients with ≥2 comorbidities did have poorer OS compared to women with one or no comorbidities (p<0.01).

Conclusion The vast majority of both older and younger patients underwent vulvar surgery. Older patients less often received groin surgery compared to younger patients. The majority of older patients had at least one comorbidity, but this did not impact treatment choice. The poorer survival in older VSCC patients may therefore be due to death of competing risks instead of VSCC itself.
