Anti-PD-1 antibodies (Abs) are among the optimal adjuvant therapies for melanoma at high risk of recurrence, especially BRAF wild-type melanoma, but the anti-tumour effects of anti-PD-1 Abs in the adjuvant setting for acral melanoma have not been evaluated previously. The aim of this study was to analyse the efficacy and safety profiles of anti-PD-1 Ab monotherapy in the adjuvant setting in an Asian population including a high ratio of acral melanoma. The efficacy and safety profiles of anti-PD-1 Ab monotherapy in the adjuvant setting were retrospectively analysed in 78 Japanese patients with advanced melanoma, including 31 cases (40%) of acral melanoma. Overall relapse-free survival was 60.3% (47 of 78 cases, 95% confidence interval (CI) 49.2-70.4%), and 39.7% of patients (31 of 78 patients, 95% CI 29.6-50.8%) relapsed during the adjuvant PD-1 Ab treatment. Six cases (7.9%) discontinued the protocol due to serious adverse events. One case (1.3%) discontinued the protocol due to trauma. The relapse-free survival of acral melanoma was 25.8%, whereas that of high cumulative sun damage was 60.0%, and that of low cumulative sun damage was 57.1%. The acral type had a significantly lower 12-month relapse-free survival than other cutaneous types (p = 0.029). The acral type appeared to be an independent prognostic factor on multivariate analysis (p = 0.015). Adverse events due to anti-PD-1 antibody were observed in 37.1% overall. The results of this study suggest that anti-PD-1 Ab therapy in the adjuvant setting is less effective for acral melanoma than for other cutaneous types.
Background: In the development of plantar melanoma, it is suspected that mechanical stress caused by weight-bearing activities, such as walking, rather than ultraviolet exposure, may play a significant role, showing a concentrated prevalence in areas of the foot where weight-bearing actions are prevalent. However, research investigating whether such mechanical stress influences disease prognosis has been limited. This study was designed to investigate the association between weight-bearing activity and the oncologic outcomes of patients with plantar melanoma.
Introduction: This article presents a case of nail unit melanoma (NUM), highlighting the unusual clinical presentations as those originating from the hyponychium. We discuss how dermoscopy is an essential tool for this pigmented lesion, and how the lack of a standardized guide for NUM underscores the importance of personalized approaches to ensure the best possible outcomes.
Case Presentation: A 72-year-old woman presented with a melanocytic lesion on her right second finger, characterized by a hyperpigmented macule with irregular borders and a heterogeneous distribution of pigment.
Child mental health has declined worldwide, with research suggesting a link to increased screen time, particularly from smartphones and social media.
Most studies show that high usage of screens correlates with negative mental health outcomes, especially among teenage girls, and some studies indicate that this relationship can be bidirectional.
Interventions aimed at reducing screen time have been shown to improve mental well-being in experimental studies.
