Harvey W. Kaufman, MD, on Cotesting for Cervical Cancer


The researcher from Quest Diagnostics spoke about a recent study which confirmed the benefit of using liquid-based cytology in cotesting for cervical cancer.

A study of 9-year cotest results performed by Quest Diagnostics confirmed the value of the liquid-based (Papanicolaou) cytology element in cotesting for cervical cancer.

The results, published in the American Journal of Clinical Pathology, demonstrated that the rates of positive cervical screening test results with both liquid-based cytology and HPV testing decline as the interval between cotesting and cotesting preceding cervical cancer (CxCa) diagnosis increases.

“This study and all previous large US cotesting studies have shown that both abnormal cytologic and HPV-positive test results decline progressively as time before CxCa diagnoses increases, most likely due to smaller lesional size and increased difficulty in sampling infected lesional cells,” the authors wrote.

Notably, these findings contradict the newly updated guidelines released by the American Cancer Society, which suggest the use of primary HPV testing and the phasing out of cytology and cotesting.

In an interview with CancerNetwork®, Harvey W. Kaufman, MD, senior medical director and director of the Health Trends Research Program at Quest Diagnostics, discussed the study findings and what he believes should be recommended regarding cervical cancer screening.

Treatment with tisotumab vedotin may be a standard of care in second- or third-line recurrent or metastatic cervical cancer, says Brian Slomovitz, MD, MS, FACOG.
Domenica Lorusso, MD, PhD, says that paying attention to the quality of chemoradiotherapy is imperative to feeling confident about the potential addition of pembrolizumab for locally advanced cervical cancer.
Following the results of the phase 3 CALLA trial, Jyoti S. Mayadev, MD, discusses the importance of global clinical multidisciplinary efforts in the locally advanced cervical cancer space.
The randomized, placebo-controlled, double-blind phase 3 CALLA trial assessed the combination of durvalumab and chemoradiotherapy vs placebo and chemoradiotherapy.
Findings from the phase 3 CALLA trial indicated that intensity modulated radiation therapy was administered in 88.1% of patients with high-risk locally advanced cervical cancer treated with durvalumab and chemoradiotherapy vs 88.1% with placebo and chemoradiotherapy.
Jyoti S. Mayadev, MD, indicated that durvalumab (Imfinzi) plus chemotherapy resulted in low rates of high-grade late-onset toxicities in the phase 3 CALLA trial, which may be due in part to the quality of the technology employed during the study.
Jyoti S. Mayadev, MD, indicated that future research for cervical cancer will be focused on combination immune checkpoint inhibitors and biomarker research.
Durvalumab appeared to have no impact on the ability to deliver safe and timely radiation therapy to patients with high-risk locally advanced cervical cancer, according to Jyoti S. Mayadev, MD.
The 12-month progression-free survival rates among patients with high-risk locally advanced cervical cancer were comparable with durvalumab plus chemoradiotherapy vs placebo plus radiotherapy.
