Sentinel lymph node biopsy for melanoma in the older population: A prospective analysis of outcomes.
Journal of Surgical Oncology 2024 March 5
BACKGROUND: The use of sentinel lymph node biopsy (SLNB) in the older population, defined as those over 70 years old, has been debated since the adoption of SLNB into routine practice. Interestingly, there remains a paucity of evidence, especially regarding the rates of SLNB positivity, complications, and subsequent adjuvant therapy in those with node positivity.
METHOD: Data on patient's comorbidities, positivity rates, complication rates, and subsequent adjuvant treatments were collected prospectively from 998 patients (644 patients < 70 and 354 patients ≥ 70 years old) between 2016 and 2022.
RESULTS: Patients aged ≥ 70 were found to have a higher prevalence of comorbidities, including hypertension, diabetes and hyperlipidaemia. The mean Breslow thickness was 2.2 and 2.5 in the under and over 70 groups respectively (p = 0.03). The mean mitotic rate was found to be 3.3 in the under 70 s and 4.1 in the over 70 s (p = 0.02). Despite these results, no significant differences were observed in the positivity rates of sentinel lymph node biopsies or in the treatment options selected for positive results. The under 70 s were more likely to experience loss of sensation (p < 0.01), but no difference was found in the total number of complications between the two groups.
CONCLUSION: Although patients aged 70 and above had a greater incidence of comorbidities, the study revealed that they had lower complications rates and there was no significant variation in the SLNB positivity rate or chosen treatment options between the two age groups. This study supports the move to physiological rather than chronological age assessments in SLNB of the elderly.
