Faden, MD, a head and neck surgical oncologist and investigator in the Mike Toth Head and Neck Cancer Research Center at Mass Eye and Ear, and assistant professor of otolaryngology–head and neck surgery at Harvard Medical School. Credit: Mass Eye and Ear Researchers at Mass Eye and Ear and Mass General Hospital have developed a blood test, or liquid biopsy, for head and neck cancer associated with the human papilloma virus (HPV) that was shown in a new study to be more accurate, faster and cheaper than conventional testing methods. In the study, published December 2 in Clinical Cancer Research, a journal of the American Association for Cancer Research, liquid biopsy was more than 98 percent accurate and obtained a diagnosis 26 days quicker on average than conventional tissue biopsy. The cost of the novel test was 38 percent lower than standard methods. When the researchers combined the liquid biopsy with findings from routine imaging and physical exam to create a fully non-invasive diagnostic approach, diagnostic accuracy remained greater than 95 percent. With HPV-associated head and neck cancer rates on the rise, there is a great need for more accurate, less-invasive, faster and less expensive diagnostic tests, according to authors of the study. "Current diagnostic approaches for HPV-associated head and neck cancers are imperfect and invasive, which means patients often need repeat biopsies to get to [...]

Treatment Paradigms Are Shifting for Locally Advanced HPV-Positive Head and Neck Cancers

Date: November 18th, 2021 Authors: Kaveh Zakeri, MD, MAS, Nancy Y. Lee, MD Source: OncLive The standard of care for patients with locally advanced head and neck squamous cell carcinomas does not substantially differ according to human papillomavirus (HPV) status in the National Comprehensive Cancer Network guidelines.1 Resectable tumors can be treated with surgery followed by adjuvant therapy. Alternatively, definitive chemoradiation therapy with cisplatin is the other dominant treatment paradigm. Incidence of HPV-associated oropharyngeal squamous cell carcinoma has increased rapidly and is associated with higher overall survival (OS) compared with cancers caused by smoking and alcohol.2,3 Given the unique biology of HPV-associated oropharyngeal disease, a separate staging system was developed for these tumors.4 HPV-associated oropharyngeal cancers are more radiosensitive and chemosensitive than cancers caused by smoking and alcohol, yet the traditional treatment paradigms—including high doses of radiation and chemotherapy—were developed prior to the epidemic of HPV-associated disease. De-escalation of therapy has been proposed for HPV-associated oropharyngeal cancer based on data demonstrating high OS and progression-free survival (PFS).5 De-escalation of therapy has been investigated for both definitive surgical and chemoradiation therapy paradigms. Most de-escalated approaches focus on selecting patients according to clinical features, such as disease stage and smoking status, whereas personalized de-escalation reduces treatment intensity for patients according to treatment response. Transoral Robotic Surgery Followed by Adjuvant Radiotherapy Transoral robotic surgery (TORS) is a minimally invasive approach that reduces morbidity compared with traditional, open surgery for patients with oropharyngeal cancers. TORS is a standard of care option for patients with [...]

Liquid biopsy provides accurate, fast Dx of HPV-associated head and neck cancer

Source: www.medpagetoday.com Author: Mike Bassett, Staff Writer, MedPage Today The use of liquid biopsy for the diagnosis of human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) was more accurate, faster, and less expensive than standard tissue-based biopsies, according to a prospective observational study. The sensitivity and specificity of this circulating tumor HPV DNA-based approach were 98.4% and 98.6%, respectively, with positive and negative predictive values of 98.4% and 98.6%, reported Daniel L. Faden, MD, of Massachusetts General Hospital and Harvard Medical School in Boston, and colleagues. The diagnostic accuracy of this non-invasive approach was significantly higher than standard of care (Youden index 0.968 vs 0.707, P<0.0001), they noted in Clinical Cancer Research. In addition, liquid biopsy reduced the time to diagnosis from a median of 41 days to 15 days, and estimated costs associated with this method were about 36% to 38% less than the traditional biopsy approach. "Currently the way we diagnose HPV-associated cancer is either with a needle biopsy of a neck lymph node or a tissue biopsy from the oropharynx -- and these approaches have a couple of different limitations," Faden told MedPage Today. Not only are they invasive and painful for patients, but needle biopsy of a neck lymph node has high failure rates due to a lack of adequate cellular material. "So, patients might have to undergo a repeat biopsy to get the diagnosis we are waiting for," he noted. "That adds time to diagnosis, and we know that time from presentation to [...]

Etiglimab/Nivolumab combination shows promise in solid tumors

Source: www.targetedonc.com Author: Sara Karlovitch The combination of etigilimab, an anti-TIGIT antibody, in combination with nivolumab (Opdivio) has demonstrated anti-tumor efficacy and acceptable safety data in patients with solid tumors, according to a press release on the interim results of the phase 1b/2 ACTIVATE trial by Mereo BioPharma Group plc. The phase 1b/2 study (NCT04761198) has a target enrollment of 125 participants and an estimated study completion date of June 2023. The primary end point is objective response rate. During the study, patients will receive an infusion of etigilimab every 2 weeks and an infusion of nivolumab every 2 weeks. Cohorts include squamous cell carcinoma of the head and neck, cervical cancer on or after chemotherapy, gastric or gastroesophageal junction adenocarcinoma, endometrial carcinoma, tumor burden high and microsatellite stable solid tumors, rare disease with high TIGIT expression, ovarian cancer, and endometrial carcinoma post standard of care therapy. At the time of data cutoff, 22 patients were included in the safety analysis. Twenty patients were evaluable with a minimum of at least one scan and 15 were included in the efficacy analysis. The analysis found that 1 patient in the cervical cancer cohort had a complete response. In the ovarian cancer cohort, 1 patient had a partial response. Four patients with stable disease was seen in ovarian cancer, cervical cancer, and uveal melanoma. Additionally, the ovarian cancer cohort has crossed futility for expansion into the second stage of the study. The combination was found to be well tolerated, and no new [...]

Geographic disparities in head and neck cancer survival in Upstate New York 2011-2019

Source: www.docwirenews.com Author: DocWire News Featured Reading This article was originally published here Head Neck. 2021 Nov 29. doi: 10.1002/hed.26945. Online ahead of print. ABSTRACT PURPOSE: To examine the association between distance to care-center and urban-rural residence on 5-year overall survival (OS) from head and neck cancer (HNC). MATERIALS AND METHODS: Five-year OS was retrospectively measured from date of initial diagnosis for patients with HNC treated at a single tertiary care center. Distances were calculated based on ZIP code of patient’s residence and care center. Multilevel Weibull regression was used to adjust for confounders and identify disparities in 5-year all-cause mortality. RESULTS: A total of 670 patients included in study. Multivariable analysis revealed older age or late-stage cancer at diagnosis, and HPV negative status were associated with poorer OS. Patients residing in isolated small rural town (HR = 2.20, p = 0.015) or small rural town (HR = 2.07, p = 0.015) had lower OS. Distance to care center was not associated with OS (HR = 0.996, p = 0.11). CONCLUSIONS: Greater rurality was associated with poorer OS among HNC patients in Upstate New York.

Oral cancer and COVID-19

Source: dentistry.co.uk Author: Seb Evans The Dental Defence Society explain how COVID-19 has impacted the detection of oral cancer and what dental teams should do to improve outcomes. Referrals for oral cancer have fallen dramatically since the start of the pandemic. This is raising fears that many cases have gone undiagnosed because of disruption to routine dental care. Missed opportunities for early detection mean it is likely that thousands of patients will eventually present with late-stage disease and poor prognosis. They will also require aggressive and complex treatments that diminish their quality of life. As well as adding to the burden on the healthcare system. Now more than ever, dental teams must prioritise the prevention, early detection and rapid referral of oral cancer. They will play a vital role in mitigating the ongoing impact of the pandemic on outcomes for this cancer through performing examinations at every opportunity, recognising when a patient presents with signs and symptoms, and raising awareness. Increasing burden of oral cancer in the UK The most recent figures on mouth cancer in the UK align with the global trend. They shows an alarming rise in incidence and mortality. The State of Mouth Cancer UK Report 2020/21 reports that last year 8,722 people were diagnosed with mouth cancer. And an estimated 2,702 people died from the disease. That’s up 58% and 48%, respectively, from a decade ago. Early detection and rapid referral for treatment makes a huge difference for patients with oral cancer. It boosts survival from [...]

Detecting suspicious lesions: what do I say next?

Source: dentistry.co.uk Author: Philip Lewis Dental team members are amazing. They put patients at their ease and provide treatment for their dental issues. They improve smiles, boost self-confidence and they save lives. Yes, you read that right. There aren’t many opportunities for dental team members to be lifesavers. Detecting mouth cancer at an early stage is one of them. It’s an initiative for the whole dental team. Both clinical and non-clinical team members have a vital part to play. From a receptionist noticing changes in a patient’s voice, a practice manager spotting a swelling they haven’t seen before to a clinician picking up on a soft-tissue abnormality, we all get the chance to be pivotal in protecting a patient’s wellbeing. Risk factors We know there are risk factors we should be aware of: the use of tobacco in any form, regular use of alcohol, especially spirits, social deprivation with its associated problems of nutrition and vitamin deficiency. It is understood that increasing age is a factor and that men are more likely than women to get the disease. We appreciate the significant effects of infection that certain strains of HPV have had recently but realise how important it is to examine all adults. Many sufferers have no identifiable risk factors. During the clinical examination, we’ll be looking for anything unusual, including: Red, white or mixed patches Ulcers that don’t heal within a maximum of three weeks Swellings Changes to normal appearance or texture and lumps in the face or neck [...]

Improving the management of HNSCC: next steps

Source: www.cancernetwork.com Author: Victoria Meucci Villaflor, MD, Cesar Perez, MD Dr Cesar Perez reacts to the utilization of next-generation sequencing in head and neck squamous cell carcinoma and highlights future areas of study. Video of interview here. Victoria Meucci Villaflor, MD: With solid tumor oncology moving more toward precision medicine or personalized medicine, where do you think head and neck cancer is going? Cesar Perez, MD: The data that we discussed from the RUN-HN trial have shown us that there’s a role for personalized medicine in head and neck cancer. We’ve seen more value in sequencing for this population that we weren’t finding much before, besides checking for PD-L1 by immunohistochemistry. Next-generation sequencing probably has a new role in this disease. I hope that this is just the tip of the iceberg of what we can accomplish by doing sequencing on our patients with head and neck cancer. Victoria Meucci Villaflor, MD: Dr Perez, are you using next-generation sequencing on all of your patients with head and neck cancer? Cesar Perez, MD: Yes. Until recently, we weren’t finding that much value in doing next-generation sequencing in patients with head and neck squamous cell carcinoma. But based on all the trials in clinical development, I’m now doing next-generation sequencing on every patient in the metastatic and recurrent setting to find those patients with a high TMB [tumor mutational burden], for example, who might not have good PD-L1. But I’m mainly doing it for clinical trial purposes, so we can then try [...]

Two markers help predict head and neck cancer prognosis

Source: labblog.uofmhealth.org Author: news release, University of Michigan Health Rogel Cancer Center A new study from the University of Michigan Health Rogel Cancer Center finds circulating tumor DNA, or ctDNA, levels can predict as early as two weeks after starting treatment which patients are likely to have good outcomes. At the same time, specialized MRI and PET scans two weeks after starting chemoradiation also correlated with outcomes. “Rates of throat cancer have steadily increased in recent years, driven by HPV infections, fueling the need for biomarkers to help guide treatment decisions, especially for locally advanced disease,” said senior study author J. Chad Brenner, Ph.D., associate professor of otolaryngology at Michigan Medicine. “Quantitative imaging of metabolism, local blood volume density and cell density from PET and MRI scans have shown both prognostic value in predicting treatment outcome as well as utility in selecting patients for additional focal radiation treatment,” said study author Yue Cao, Ph.D., professor of radiation oncology and radiology at Michigan Medicine. The researchers conducted a randomized trial of patients with stage 3 oropharyngeal squamous cell carcinoma. In total, 93 patients had imaging and 34 also had blood tests before starting chemoradiation and again at two, four and seven weeks after treatment. The study found that HPV ctDNA clearance at two weeks, but not at four weeks, predicted outcomes. The metabolism, local blood density and cell density before radiation therapy or at two weeks after starting treatment predicted outcomes as well. These early predictor biomarkers could help determine which [...]
