The median duration of treatment was 8.6 months,
whereas the median follow-up was 11.4 months. Around Figure 2. Reasons for stopping treatment
one-third of patients (n = 30; 31.6%) were still receiving
immunotherapy at the end of the data collection phase,
while 65 patients (68.4%) had already stopped treatment.
3.3. Efficacy
Figure 3 displays OS at 24 months, in patients with local
disease recurrence and distant recurrence (hazard ratio
[HR]: 0.75; 95% CI: 0.318 – 1.764; P > 0.05).
The 24-month OS rate was 95% (Figure 4), with
a median OS time not yet reached. In our cohort,
4 patients (3.8%) died, with three deaths attributed
to melanoma. The RFS and DRFS rates were 73%.
Overall, the median time to recurrence was 3.3 months.
Specifically, distant recurrence occurred at a median Figure 3. 24 months of overall survival in local and distant disease
of 3.5 months, while melanoma local recurrence had a recurrence groups
median of 2.9 months.
experienced both local and distant recurrence. After
Recurrence occurred in 19 patients (20%). Among these recurrence, 8 patients (8.4%) were treated with systemic
cases, 7 patients (7.3%) had local recurrence, 10 patients therapy, 6 patients (6.3%) had both local and systemic
(10.5%) had distant recurrence, and 2 patients (2.1%) therapy, 4 patients (4.2%) had only local therapy, and only
