In surveillance of HPV+ anal cancer, inconclusive exam and imaging results are common, especially for patients in early surveillance. In a study of 233 patients, 42% received at least one clinically indeterminate finding (CIF) during follow-up. 46% of these CIFs were from exams and 54% were from imaging. [1] 

Join us for an industry expert theater at the ASTRO Annual Meeting, happening now, to see how clinicians can gain new insight into equivocal findings:

NavDx® is pleased to be a sponsor of the 2026 Head and Neck Cancer Survivorship Symposium, presented by @hncalliance and @AHNSinfo on July 18 beginning at 8:30am Eastern.

Life after cancer can be a difficult time, especially for those recovering from head and neck cancer. This event brings together survivors, caregivers, patients in treatment, and healthcare providers to hear from medical experts, learn practical strategies for life after treatment, and connect with others who understand what patients are going through.

The California Head and Neck Consortium (CHNC) recently published landmark recommendations on the use of circulating tumor HPV DNA (ctHPVDNA) assays for post-treatment surveillance of HPV+ oropharyngeal cancer. 

Thirty-three multidisciplinary experts from 15 institutions established:

✔ ctHPVDNA offers greater specificity and sensitivity and shortens time to detection of recurrence
✔ Serial testing is recommended over single post-treatment time-point testing
✔ Serial testing is recommended in years 1–5, alongside routine surveillance visits
✔ Detection of ctHPVDNA without clinical confirmation of recurrence should prompt more frequent imaging 

Experts from CHNC will do a deep dive into these insights at a lunch symposium at the American Head and Neck Society’s 12th International Conference. Join us Sunday, July 19th at 12:15pm in Room 258C at AHNS 2026. We hope to see you there!

As Pride Month comes to a close, let’s talk about some populations that are too often left out of the HPV-cancer conversation. HPV+ anal cancer incidence is significantly elevated among men who have sex with men (MSM) and people living with HIV. When both factors are present, the incidence is substantially higher. Published cohort studies report incidence ranging from approximately 5-46 per 100,000 person-years for either factor alone, rising to 85-131 per 100,000 among HIV-positive MSM specifically [1,2], compared to roughly 1.5-2 per 100,000 among the general U.S. population.[3] 

Equitable, informed cancer care starts with awareness of patient populations at higher than average risk, especially those who face disparities. This Pride Month, we thank all Clinicians who are providing LGBTQ-competent care for patients with HPV-driven cancers.

For HPV+ OPSCC patients undergoing CRT, their blood may tell you how treatment is working before imaging can.

TTMV®-HPV DNA kinetics during definitive CRT correlate with treatment response: 

1. Rapid decline at week 4 may predict mid-treatment tumor volume reduction, and clearance by end-of-treatment is associated with excellent disease-free survival. [1,2] 
2. In patients undergoing induction chemotherapy, ctHPVDNA clearance after the first IC cycle predicted final disease control with significantly greater accuracy than PET-CT (61.5% vs. 7.7%, p=0.01). [3] 
3. Persistent or rising TTMV-HPV DNA during or after CRT may signal treatment failure, often before imaging confirms it. [1]

Pro Tip for Patient Navigation: Making Surveillance Convenient

One of the most common barriers to consistent post-treatment surveillance? Getting patients to complete imaging or bloodwork. Sometimes they can’t take time off work. Sometimes it’s too far to travel.

NavDx® testing can help fill this gap. Testing requires only a standard blood draw, and Naveris® can help arrange convenient phlebotomy options that remove logistical barriers for your patients. We can arrange for a blood draw at their home, workplace, or a walk-in clinic near to them. Results still come directly to you, even if the patient can’t.

If surveillance compliance is a challenge in your practice, ask our Clinical Operations Team about Naveris-arranged Phlebotomy, or learn more here. https://t.co/D0bRBqF3JE

May is Asian American and Pacific Islander Heritage Month. Did you know the AAPI community faces significant disparities when it comes to OPSCC?

More than 70% of Native Hawaiian and Other Pacific Islander (NHOPI) patients present with advanced stage (III/IV) head & neck cancer (both HPV+ and HPV-), compared to 63.8% of white patients and 60.7% of Asian patients. Five-year overall survival for NHOPI patients is 49.0%, compared to 53.9% for white patients and 57.4% for Asian patients. [1]

Disparities in access, screening, and post-treatment follow-up contribute to these outcomes. Recognizing which patients face elevated risk is the first step toward closing the gap.

Did you know NavDx® testing isn’t reserved for post-treatment surveillance?

While post-treatment surveillance is what the NavDx test is best known for, it also has these potential uses in the pre-treatment setting:

1. Confirming HPV+ tumor etiology, especially when tissue-based testing is inconclusive or if FNA is hypo-cellular.
2. Confirming HPV genotype
3. Establishing a baseline that adds prognostic and clinical context to future testing
4. Resolving inconclusive ambiguous clinical and radiological findings related to HPV-driven cancer

When we talk about post-treatment surveillance, we focus on detection. But what about the time in between surveillance visits?

A 2024 patient-reported outcomes study found that negative NavDx® test results significantly reduced anxiety and fear of cancer recurrence in HPV+ OPSCC patients—a measurable improvement in psychological wellbeing. The proportion of patients with clinically elevated distress scores dropped from 36.4% to 18.2% (p=0.031) on the NCCN Distress Thermometer. Anxiety scores improved significantly on the validated Hospital Anxiety and Depression Scale (p=0.037). Importantly, 88.4% of patients reported that testing did not introduce anxiety, and 100% felt some measure of confidence in the assay as a monitoring tool. [1]

This Mental Health Awareness Month: surveillance isn’t only about catching recurrence. For many patients, a negative result may be one of the most reassuring things they receive.

Ten years ago, liquid biopsy in HPV+ cancer was a hypothesis.

Today, TTMV®-HPV DNA surveillance has been validated across multiple prospective studies, expert consensus recommendations, and a systematic meta-analysis with pooled sensitivity of 86% and specificity of 96% across 12 studies and more than 1,300 patients. [1]

That’s what a decade of focused research looks like.

May is Oncology Nursing Month, and we want to recognize the nurses who are on the front lines of HPV+ cancer care.

From coordinating surveillance schedules to preparing patients for what life after treatment looks like, you’re the ones making sure patients don’t fall through the cracks.

Thank you for the work you do every day.

HPV+ OPSCC carries an excellent prognosis, but recurrence still occurs in 15–25% of patients. When it does, timing matters.

Post-treatment NavDx® testing can detect recurrence with a median lead time of 4 months before clinical or imaging-confirmed findings [1], 89% sensitivity and 97% specificity. [2] With an NPV of 98%, a negative result provides meaningful reassurance alongside clinical surveillance. [2]

One blood draw. Information that imaging can’t always provide this early. Reassurance your patients find priceless.

Facts to consider about HPV+ head & neck cancer recurrence:

1. Traditional surveillance is inherently limited. The field of view is restricted to local anatomy. Exam accuracy may be reduced due to post-treatment inflammation and fibrosis. 
2. ~50% of recurrences occur outside the head and neck.[1] Many present as distant metastases.
3. 75% of patients with recurrence are asymptomatic at detection with the NavDx® test.[2]

Facts to consider about the NavDx test:

1. It’s designed to detect a whole-body molecular signal and is not confined by an imaging field, by visual exam, or by palpation.
2. It detects minimal residual and distant metastatic disease.
3. It is not impacted by any post-treatment physical changes.

In practice, the NavDx test shifts surveillance from “what can we see” to “what biology is active.” After all, if recurrence can be systemic, your surveillance should be too. https://t.co/wVt1Aq5ccF
