Abstract

Introduction: Programmed death receptor 1 inhibitors are widely used tumor immunotherapy agents, yet they frequently trigger immune-related adverse events (irAEs), among which severe cutaneous toxicities are life-threatening and often interrupt anti-tumor treatment. Conventional Western medicine relying on glucocorticoids carries notable side effects, while integrated traditional Chinese medicine and Western medicine (TCM-WM) offers a promising alternative therapeutic strategy. This work aims to explore the clinical efficacy and safety of combined TCM-WM intervention for severe tislelizumab-induced cutaneous irAEs, elaborate traditional Chinese medicine (TCM) syndrome differentiation logic, and accumulate clinical evidence for managing such severe skin adverse reactions.

Case presentation: A 71-year-old male patient with right lung squamous cell carcinoma complicated by supraclavicular lymph node metastasis developed grade 3 severe cutaneous irAE after tislelizumab immunotherapy, diagnosed with TCM syndrome of intermingled damp-heat, stasis, and toxin. Comprehensive Western medicine treatment (glucocorticoids, antihistamines, topical anti-inflammatory ointments, and analgesics) combined with individualized oral modified TCM granules, external herbal washing, and characteristic TCM therapies was implemented. After 12 days of inpatient treatment and 3 months of continuous follow-up, the patient's severe rash, skin pain, and pruritus were fully resolved without recurrence. The…

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
