Abstract


Background: Immunotherapy agents offer novel treatment options in advanced cancers. However, their use is limited in developing countries lacking unifying guidelines and can be followed by a financial burden. In this study, we aimed to provide an overview regarding the use of immunotherapy and the overall response to treatment in patients with metastatic disease in relation to cost-effectiveness.

Methods: This was a retrospective study involving adult metastatic cancer patients, treated with programmed cell death-1 (PD-1) inhibitors at American University of Beirut Medical Center (AUBMC), a tertiary cancer center in Lebanon. Study enrollment began on January 1, 2014 and ended on January 12, 2016. Baseline demographics, epidemiological and clinical data were collected from the patients' records.

Results: Our study consisted of 34 patients. Fifteen patients self-financed the treatment. The patients were prescribed immunotherapy without programmed cell death-ligand 1 (PD-L1) testing as it was not part of the guidelines at the time. Twenty-two patients were treated with nivolumab and 12 patients with pembrolizumab. Thirteen patients showed partial response or stable disease, while 21 patients showed progression.

Conclusion: Improvement in terms of overall survival and progression-free survival has been undercut by the lack of availability of these drugs and their cost. Considering that a large percentage of patients do not respond to immunotherapy, there is a need to use guidelines such as a preset PD-L1 level that ensure cost-effectiveness and prevent resource waste.
