Summary

Therapeutic agents used in malignant melanoma treatment such as BRAF/MEK inhibitors and anti-CTLA-4/Anti-PD-1 antibodies go along with harmful side effects in a considerable proportion of patients and treatment costs may cause relevant medical expenditures per month. Currently, therapy response assessment in melanoma patients is performed using RECIST criteria which are based on changes in tumour size. PET/CT combines morphological and metabolic information. Thus, the so-called PERCIST-criteria were introduced integrating change in size and glucose utilization for response assessment in solid tumors. Due to the different mechanism of action these new agents introduce different response patterns increase in tumor size due to inflammation for antibody therapies). In conventional chemotherapies, re-staging is usually performed 3 months after treatment initiation which is the result of empirical investigations. Moreover, it has recently been shown, that response to new targeted therapies can be detected much earlier using PET or functional MR techniques. This forms the rationale for the monitoring of melanoma patients using a combined PET/MR technique after only 2 weeks of therapy initiation. Especially for patients in stage IV with a medium survival time of 12 months, a 2.5 months earlier re-staging and therapy adjustment would have significant consequences for the individual clinical course.

Conditions

  • Malignant Melanoma Stage IV

Interventions

DIAGNOSTIC_TEST

PET/MR (Biograph mMR)

The combination of PET and MRI allows for evaluation of metabolic, functional and morphological parameters such as glucose metabolism, perfusion, diffusion restriction or size in one examination. Due to the combination of MRI and PET in one scanner it is possible to align the acquired PET and MR datasets with high precision
