Treatment for cervical cancer with immunotherapy: Understanding the process and outcomes
In the fight against cervical cancer, a significant breakthrough has been made with the use of immunotherapy, particularly with the checkpoint inhibitor, Pembrolizumab. This drug has demonstrated significant effectiveness for advanced or recurrent cervical cancer, particularly in patients whose tumors express high levels of PD-L1.
A 2021 study revealed a higher survival rate for people with persistent, recurrent, or metastatic cervical cancer after receiving Pembrolizumab, specifically in combination with chemotherapy. In a real-world retrospective study of 44 patients treated with Pembrolizumab, a complete response rate of 23% was observed, with a median overall survival of 47.5 months and a median progression-free survival of 9.1 months. The treatment was generally safe, with only 7% of adverse events graded 3 or higher.
Pembrolizumab received accelerated FDA approval in 2018 for PD-L1 positive advanced cervical cancer after prior chemotherapy, based on the KEYNOTE-158 trial showing an overall response rate of 14.6% and rapid time to response in heavily pretreated patients. However, monotherapy with Pembrolizumab was not universally approved in all countries due to questions about additional benefit, as exemplified by Germany's initial lack of approval before 2022 despite ongoing clinical trials.
The effectiveness of Pembrolizumab varies by patient performance status. Those with better Eastern Cooperative Oncology Group (ECOG) performance scores (0-1) respond significantly better than those with poorer scores (>1), suggesting patient selection is important to maximize benefit.
In a recent development, Pembrolizumab was approved in 2021 as a first-line treatment option for cervical cancer in combination with chemotherapy for those with tumors that release the protein PD-L1.
Financial assistance may be available for those facing the high costs associated with immunotherapy treatments. Various organizations such as CancerCare, Cancer Financial Assistance Coalition, Centers for Medicare & Medicaid Services, HealthWell Foundation, and Patient Access Network Foundation offer financial aid for patients in need.
In conclusion, Pembrolizumab is proving to be an effective and safe treatment option for advanced or recurrent cervical cancer, particularly in PD-L1 positive patients. Real-world data supports durable responses and prolonged survival for some, especially those with good performance status. Further studies continue to refine its role and explore combination strategies. For those facing financial difficulties, various organizations offer financial aid to help cover the costs of treatment.
- Science has played a crucial role in the development of therapies and treatments for cancer, such as immunotherapy and chemotherapy, as evidenced by the approval of Pembrolizumab for advanced or recurrent cervical cancer.
