Plasma rich in growth factors for the treatment of rapidly progressing refractory corneal melting due to erlotinib in nonsmall cell lung cancer

RATIONALE:
Erlotinib, an antineoplastic agent, is indicated for the treatment of patients with advanced nonsmall cell lung cancer. Most common adverse events are manageable, although more severe ones require dose reduction or discontinuation of erlotinib treatment.

PATIENT CONCERNS:
We present a case of severe corneal ulcer treated with autologous plasma rich in growth factors.

DIAGNOSES:
A 76-year-old woman with stage IVB (cT2a N0 M1c) lung cancer under erlotinib treatment presented with rapidly progressing corneal ulcer. Evolution was torpid and refractory to conventional treatment.

INTERVENTIONS:
Surgical options were dismissed because of the poor performance status of the patient. Despite temporary discontinuation of erlotinib treatment, the corneal ulcer continued to worsen with peripheral corneal neovascularization, stromal thinning, corneal edema, and profuse inflammation of the ocular surface.

OUTCOMES:
Treatment with autologous plasma rich in growth factors prevented an imminent corneal perforation and improved the corneal ulcer for over a year of follow-up.

LESSONS:
Considering the poor results of conventional treatment, both medical and surgical, management of the inflammation of the ocular surface together with the stimulation of the healing processes through regenerative therapy such as PRGF, can be an option worth considering in these cases.
