Abstract:
Cervical cancer is the fourth most common cancer in women worldwide, and prognosis is poor for those who experience recurrence or develop metastatic disease, in part due to the lack of active therapeutic directions. The National Cancer Institute convened a Cervical Cancer Clinical Trials Planning Meeting in October 2018 to facilitate the design of hypothesis-driven clinical trials focusing on locally advanced, metastatic, and recurrent cervical cancer around the theme of enhancing susceptibility to DNA repair inhibition and DNA damage. Before the meeting, a group of experts in the field summarized available preclinical and clinical data to identify potentially active inducers and inhibitors of DNA. The goals of the Clinical Trials Planning Meeting focused on identification of novel experimental strategies capitalizing on DNA damage and repair (DDR) regulators and cell cycle aberrations, optimization of radiotherapy as a DDR agent, and design of clinical trials incorporating DDR regulation into the primary and recurrent or metastatic therapies for cervical carcinoma. Meeting deliverables were novel clinical trial concepts to move into the National Clinical Trials Network. This report provides an overview for the rationale of this meeting and the state of the science related to DDR regulation in cervical cancer.
Insights
Cervical cancer treatments are limited for advanced stages. Experts met to design clinical trials targeting DNA damage and repair (DDR) to improve outcomes for recurrent and metastatic cervical cancer.
Area of Science:
- Oncology
- Genetics
- Cancer Research
Background:
- Cervical cancer is a leading cause of cancer death in women globally.
- Prognosis is poor for recurrent or metastatic cervical cancer due to limited therapeutic options.
- DNA damage and repair (DDR) pathways are critical in cervical cancer progression.
Framework:
- A National Cancer Institute meeting convened experts to design clinical trials for advanced cervical cancer.
- Focus on enhancing susceptibility to DNA repair inhibition and DNA damage.
- Exploration of novel strategies targeting DDR regulators and cell cycle aberrations.
Implementation:
- Summarized preclinical and clinical data to identify DNA damage and repair modulators.
- Optimized radiotherapy as a DNA damage response agent.
- Designed clinical trials integrating DDR regulation into primary and advanced cervical cancer therapy.
Implications:
- Generated novel clinical trial concepts for the National Clinical Trials Network.
- Aimed to improve therapeutic strategies for locally advanced, metastatic, and recurrent cervical cancer.
- Advanced the understanding of DDR regulation in cervical cancer treatment.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
