Post-oncologic skin health: cutaneous recovery and rehabilitation after cancer treatments

Background Advances in oncology have markedly improved cancer survival, however, chronic cutaneous sequelae induced by chemotherapy, radiotherapy, targeted therapies, and immunotherapies remain common and may persist long after treatment completion. These long-term skin changes, ranging from xerosis and pruritus to pigmentary alterations, fibrosis, and immune-mediated dermatoses, can substantially impair quality of life and functional recovery. Objective To define the evolving role of dermatology in post-oncologic skin health and to critically synthesize mechanistic and clinical evidence supporting long-term dermatologic rehabilitation strategies. Methods A structured search of PubMed and MEDLINE (2010–2025) identified clinical and mechanistic studies, consensus guidelines, systematic reviews, and cohort data relevant to post-treatment cutaneous sequelae. Eligible publications included human studies addressing chronic skin changes after cancer therapy or evaluating therapeutic approaches applicable to survivorship dermatology. The search yielded 612 records, of which 148 full-text articles were reviewed and 54 met the inclusion criteria for synthesis. Results Post-oncologic skin care extends beyond symptomatic management to encompass restoration of epidermal barrier function, mitigation of chronic inflammation, support of the cutaneous microbiome, and improvement of psychosocial well-being. Mechanistic studies highlight persistent structural, immunologic, molecular, and microbial alterations that underline delayed skin recovery. Within this context, photobiomodulation and selective energy-based modalities may support long-term cutaneous resilience, however robust clinical evidence of their benefit is lacking. Conclusion Dermatologists play a central role in survivorship care by transitioning cutaneous management from symptomatic treatment toward preventive, restorative, and rehabilitative strategies that improve long-term quality of life.
