Sustained remission of Parkinson disease associated melanoma with immunotherapy Keywords: Tremor Parkinson disease Dopa-responsive dystonia
Parkinson disease (PD) is associated with a melanoma risk 3e21 times higher than the general population [1]. Ipilimumab is a T-cell activating agent (monoclonal antibody to cytotoxic T-lymphocyte antigen-4) recently approved for stage IV melanoma, with central nervous system (CNS) activity [2]. This mechanism raises potential safety concerns, given that neuroinflammation is a common histopathological feature of PD [3], and immune-related adverse events are common with ipilimumab [4]. We describe tolerability and outcome (including course of PD motor symptoms) in the first case (to our knowledge) of a PD patient treated with ipilimumab and whole brain radiotherapy for metastatic melanoma. Our male patient developed PD at age 50, melanoma T3 N0 M0, stage IIA at age 52, with progression to metastatic disease with brain and lung metastases at age 58. Given the limited options available for CNS metastatic disease, and concerns about tolerability in PD, we agreed to proceed with ipilimumab under close monitoring by neurology and oncology providers. The dose of antiparkinsonian drugs was optimized 5 weeks prior to initiation of ipilimumab. Our patient underwent a course of ipilimumab and whole brain radiation treatments with serial brain MRI and medical examinations. Adverse events and UPDRS-III motor scores were documented at each visit (Table 1) Unified Parkinson Disease Rating Scale-motor (UPDRS-III) “ON” score was 19 and levodopa equivalent daily dose (LEED) was 750 at baseline. Progression of brain and lung metastases was noted on restaging scans 12 weeks after initiation of ipilimumab (Fig. 1A and B). Whole brain radiation therapy was delivered weeks 12e15, with a complete response and no discernible residual tumor at the week 20 MRI scan (Fig. 1C and D). Transient symptoms of diarrhea, nausea, increased depression, and severe fatigue occurred following radiation. However; UPDRS-III score improved to 12, allowing LEED reduction to 450, at week 33. The week 44 scan showed no evidence of residual disease (Fig. 1E and F). UPDRS-III score returned to 17 and LEED to 700 at week 47. Constitutional symptoms improved after several weeks, motor symptoms progressed back to baseline, and the patient resumed his prior doses of antiparkinsonian drugs. http://dx.doi.org/10.1016/j.parkreldis.2014.05.017 1353-8020/© 2014 Elsevier Ltd.

There have been reports of immune related neurological complications including chronic inflammatory demyelinating polyradiculoneuropathy, transverse myelitis, and myositis with ipilimumab [5]. Therefore, close monitoring of neurological comorbidities may be indicated with this therapy. To our knowledge, considerations about melanoma treatment in the setting of comorbid Parkinson disease have not been studied. Our initial experience shows that ipilimumab could be tolerated, and may not worsen PD motor symptoms. However, transient improvement in motor symptoms in our patient (attributable to brain edema) following radiotherapy could have masked any symptom exacerbation. Future melanoma treatment studies should explore safety, tolerability, and efficacy in the setting of comorbid Parkinson disease and other neurological disorders.

Fig. 1. Brain magnetic resonance imaging shows brain metastases 12 weeks after ipilimumab (A and B); reduction in lesion volume at week 20 after completion of whole brain radiation (C and D); and absence of residual disease by week 44 (E and F). Images A, C, and E are T1 gadolinium enhanced MRI sequences and images B, D, and F are FLAIR MRI sequences.
