BACKGROUND: We aim to ascertain prognostic factors in the current management of anal cancer within this study.
METHODS: We reviewed the management and outcomes of anal cancer cases over a seven-year period, inclusive (2016-2023). The primary objectives were to assess the demographic characteristics, clinical presentation, and outcomes of all anal cancer patients within our institution. Kaplan-Meier survival analysis was used to estimate survival differences between cohorts, with statistical significance determined using log-rank testing. Cox proportional hazards regression was utilised to identify prognostic factors. Cox regression hazard ratios were reported along with confidence intervals and p-values.
RESULTS: The median follow-up time for the study was 29.8 months. Seventy-five patients with anal cancer were included in this study, with 88% (66/75) being squamous cell carcinoma (SCC) and the majority having regional disease (82.7% (62/75)). The median age at diagnosis was 63.4 years (36-94). There was a female preponderance (57.3% (43/75)). In total, 84% (63/75) underwent definitive chemoradiation (dCRT), with 7/63 (11.1%) requiring a salvage abdomino-perineal resection (APR) for residual or recurrent disease. Adverse prognostic indicators include those with T4 disease hazard ratio = 3.81, (95% CI 1.13-12.83, * p = 0.04), poorly differentiated tumour disease HR = 3.37, (95% CI 1.13-10.02, * p = 0.04), having N2 nodal status HR = 5.03, (95% CI 1.11-22.8, * p = 0.04), and having metastatic disease at diagnosis HR = 5.8, (95% CI 1.28-26.42, * p = 0.02).
CONCLUSION: Presenting characteristics including stage, nodal, and differentiation status remain key prognostic indicators in those diagnosed with anal malignancy.
