Bacteria could become new biomarker for testing patients’ reaction to cancer treatments which would give microbiologists and clinical laboratories a new tool for aiding diagnosis and in the selection of appropriate therapies
In a surprising study conducted at King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, British scientists have discovered that a common bacteria found in the mouth may be able to “melt” certain cancers. The bacteria could also be used as a clinical laboratory biomarker to determine how patients may react to specific cancer treatments.
The researchers found that the presence of Fusobacterium can help neutralize head and neck cancers and provide better outcomes in patients with those diseases, according to a Kings College London news release.
“In essence, we found that when you find these bacteria within head and neck cancers, [patients] have much better outcomes,” said Miguel Reis Ferreira, MD, PhD, clinical oncologist at Guy’s and St Thomas’, adjunct senior clinical lecturer at King’s College London and senior author of the study, in the news release. “The other thing that we found is that in cell cultures this bacterium is capable of killing cancer.”
“This research reveals that these bacteria play a more complex role than previously known in their relationship with cancer—that they essentially melt head and neck cancer cells,” said Miguel Reis Ferreira, MD, PhD (above), clinical oncologist at Guy’s and St Thomas’, adjunct senior clinical lecturer at King’s College London and senior author of the study, in a news release. “However, this finding should be balanced by their known role in making cancers such as those in the bowel get worse.” Should these findings prove sound, clinical laboratories may soon have a new biomarker for testing patients’ reaction to cancer treatments.

Researchers Surprised by Their Findings
The researchers began their research by using computer modeling to identify the types of bacteria to further scrutinize. They then studied the effect of those bacteria on cancer cells by analyzing data on 155 head and neck cancer patients whose tumor information had been submitted to the Cancer Genome Atlas. Head and neck cancers include cancers of the mouth, throat, voice box, nose, and sinuses.
The scientists placed Fusobacterium in petri dishes and kept the bacteria there for a few days. They observed the effect of that bacteria on head and neck cancers and discovered there was a 70% to 90% reduction in the number of viable cancer cells after being infused with the Fusobacterium.
Due to the known correlation between Fusobacterium and colorectal cancer, the team was astonished to find the cancer cells present in head and neck cancers had almost been eradicated.
In the news release, Ferreira said the researchers initially expected the Fusobacterium to boost the growth of the cancers and render those cancers more resistant to treatments like radiotherapy. However, they found the opposite to be true.
“The research in colorectal cancer indicates that these bacteria are bad, and that was kind of ingrained into our minds, and we were expecting to find the same thing,” said Ferreira in a Press Association (PA) interview, The Independent reported. “When we started finding things the other way around, we were brutally surprised.”
Predicting Better Outcomes, Lower Risk of Death
“You put it in the cancer at very low quantities and it just starts killing it very quickly,” Ferreira said in the King’s College London news release. “What we’re finding is that this little bug is causing a better outcome based on something that it’s doing inside the cancer. So we are looking for that mechanism at present, and it should be the theme for a new paper in the very short-term future.”
In addition, the scientists discovered that patients with Fusobacterium within their cancer showed improved survival rates when compared to those without the bacteria. The presence of the bacteria correlated with a 65% reduction in death risk.
“What it could mean is that we can use these bacteria to better predict which patients are more likely to have good or worse outcomes, and based on that, we could change their treatment to make it kinder in the patients that have better outcomes or make it more intense in patients that are more likely to have their cancers come back,” said Ferreira in the PA interview.
“Our findings are remarkable and very surprising. We had a eureka moment when we found that our international colleagues also found data that validated the discovery,” said Anjali Chander, PhD student, senior clinical research fellow, Comprehensive Cancer Center, King’s College London, and lead author of the study in the news release.
More to Learn about Bacteria as Biomarkers
According to the National Cancer Institute (NCI), more than 71,000 people will be diagnosed with one of the major types of head and neck cancer this year in the US and more than 16,000 patients will die from these diseases.
The Global Cancer Observatory (GLOBOCAN) estimates there are about 900,000 new cases of head and neck cancers diagnosed annually worldwide with approximately 450,000 deaths attributed to those cancers every year. GLOBOCAN also claims head and neck cancers are the seventh most common cancer globally.
More research and studies are needed to confirm the virtue of this latest venture into the human microbiome. However, the preliminary results of this study appear promising.
The study of human microbiota continues to bring unexpected surprises, as scientists gain more insights and identify specific strains of bacteria that may have a positive or negative influence on an individual’s health. These discoveries may give microbiologists and clinical laboratories intriguing new biomarkers that could be incorporated into medical tests that aid diagnosis and the selection of appropriate therapies.
Managers of pathology groups and clinical laboratories can learn from the challenges confronting the radiology profession
Members of the Intersociety Committee of the American Society of Radiology (ACR) recently met in Coronado, Calif., to discuss the “most pressing” challenges to their profession and investigate possible solutions, according to Radiology Business. Many of these challenges mimic similar challenges faced by anatomic pathology professionals.
The radiology leaders identified seven of the “most important challenges facing radiology today.” They include: declining reimbursement, corporatization and consolidation, inadequate labor force, imaging appropriateness, burnout, turf wars with nonphysicians, and workflow efficiency, according to a report on the meeting published in the Journal of the American College of Radiology (JACR).
“Solving these issues will not be easy,” said Bettina Siewert, MD, diagnostic radiologist at Beth Israel Deaconess Medical Center (BIDMC) in Boston, Mass., professor of radiology at Harvard, and lead author of the JACR report, in the JACR. “This is a collection of ‘wicked’ problems defined as having (1) no stoppable rule, (2) no enumerable set of solutions or well-described set of permissible operations, and (3) stakeholders with very different worldviews and frameworks for understanding the problem,” she added.
“The Intersociety Committee is a freestanding committee of the ACR established to promote collegiality and improve communication among national radiology organizations,” JACR noted.
“Taken together, a ‘perfect storm’ of pressures on radiologists and their institutions is brewing,” said Bettina Siewert, MD (above), diagnostic radiologist at Beth Israel Deaconess Medical Center in Boston, Mass., professor of radiology at Harvard, and lead author of the JACR report. Wise pathology and clinical laboratory leaders will see the similarities between their industry’s challenges and those facing radiology. (Photo copyright: Beth Israel Deaconess Medical Center.)
How Radiology Challenges Correlate to Pathology Practices
Here are the seven biggest challenges facing radiology practices today as identified by the Intersociety Committee of the ACR.
Declining Reimbursement: According to the ACR report, radiologists in 2021 performed 13% more relative value units (RVUs) per Medicare beneficiary compared to 2005. However, the inflation-adjusted conversion factor fell by almost 34%––this led to a 25% decline in reimbursements.
This issue has plagued the pathology industry as well. According to an article published in the American Journal of Clinical Pathology (AJCP), prior to adjusting for inflation, the average physician reimbursement increased by 9.7% from 2004 to 2024 for all included anatomic pathology CPT codes. After adjusting for inflation, the average physician reimbursement decreased by 34.2% for included CPT codes. The greatest decrease in reimbursement observed from 2004 to 2024 was for outside slide consultation at 60.5% ($330.12 to $130.49), followed by pathology consultation during surgery at 59.0% ($83.54 to $34.29). The average CAGR was -2.19%,” the authors wrote.
“Our study demonstrates that Medicare physician reimbursement for common anatomic pathology procedures is declining annually at an unsustainable rate,” the AJCP authors added.
The radiologists who identified this trend in their own field suggest that medical societies could lead the push to minimize the reimbursement cuts. Pathologists could also adopt this ‘strength in numbers’ mentality to advocate for one another.
Corporatization Consolidation: The authors of the ACR report identified this issue as limiting job opportunities for radiologists particularly in private practice. Pathology professionals have seen the same trend in their field as well. Increasingly, small pathology groups have been consolidated into larger regional groups. Some of those larger regional pathology groups will then be acquired by public laboratory corporations.
The authors of the ACR report suggest radiologists should be educated on the pros and cons of consolidation. They also suggest pursuing unionization.
Inadequate Labor Force: In both radiology and pathology there is a supply-and-demand issue when it comes to labor. Staffing shortages have been felt across all of healthcare, but particularly among pathology groups and clinical laboratories. Siewert and her co-authors suggest a three-pronged approach to address this issue:
Creating residency positions in private practice.
Recruiting international medical graduates.
Increasing job flexibility.
Pathology professionals could apply these same ideas to help close the gap between the open positions in the field and the number of professionals to fill them.
Imaging Appropriateness: A gap between service capacity and service demand for radiology imaging has created a frustrating mismatch between radiologists and clinicians. Radiology experts point to overutilization of the service causing the supply-and-demand crisis. Comparatively, pathologists see a similar issue in complex cases requiring more pathologist time to come to an appropriate diagnosis and identify a care plan.
“To facilitate this reduction, better data on imaging outcomes for specific clinical questions are urgently needed,” the authors of the ACR report wrote as a possible solution. “Considering the magnitude of the mismatch crisis, radiologists may also need to consider expanding their consultative role to include that of a gatekeeper, as is done in other more resource-controlled countries.”
Burnout: Perhaps one of the most talked about subjects in the medical field has been burnout. The issue has been thrust to the forefront with the COVID-19 pandemic; however, the burnout crisis began before the pandemic. About 78% of radiologists surveyed for this report claimed to be exceeding their personal work capacity.
The authors of the ACR report suggest a structured approach to air grievances without descending into despair. “Using a team approach based on the concept of listen-sort-empower, burnout can be combatted by fostering free discussion between frontline workers and radiologists,” they said. “Facilitators unaffiliated with the radiology department can help to maintain focus on gratitude for positive attributes of the work and the institution as well as to keep the sessions on task and prevent them from devolving into complaint sessions with a subsequent loss of hope.”
A similar approach could be applied to pathology groups and clinical laboratory to combat worker burnout as well.
Turf Wars with Nonphysicians: Over the last five years the number of imaging exams being interpreted by nonphysician providers has increased by 30%, according to the ACR report. The writers emphasized the need for increased understanding and awareness about the importance of physician-led care. They suggest solidarity among hospital medical staff to provide a united front in addressing this issue in hospital bylaws.
In pathology, the counterpart is how large physician groups are bringing anatomic pathology in-house. This has been an ongoing trend for the past 20 years. It means that the pathologist is now an employee of the physician group (or a partner/shareholder in some cases).
Increase Workflow Efficiency: Image interpretation accounts for only 36% of the work radiologists perform, the ACR report noted. This issue has a direct counterpart in pathology where compliance requirements and various tasks take time away from pathologist diagnosis. These issues could be solved by working AI into tasks, delegating non-interpretive tasks to other workers, and improving the design of reading rooms. All of these possible solutions could also be applied to clinical pathologists.
These issues being faced by radiologists compare directly to similar issues in the clinical pathology world. Pathologists and pathology group managers would be wise to learn from the experience of their imaging colleagues and possibly adopt some of the ACR’s suggested solutions.
Study findings highlight financial impact underinsured have on healthcare providers, including clinical laboratories and pathology groups
Commonwealth Fund’s 2024 Biennial Health Survey released in November shows that not only are Americans underinsured, but many are swimming in medical debt. This is not good news for clinical laboratories. Simply put, labs must collect deductibles, copays, and out of pocket amounts from insured patients. If the patient is underinsured, that means the lab probably has to collect more—even 100%—of total charges directly from the patient.
The study conducted between March and June of 2024 collected data from 8,201 respondents ages 18-64, and despite two of every three respondents carrying health insurance through their employers, one of every four is underinsured, according to a Commonwealth Fund news release.
A further 44% of respondents have medical debt, with one of every four calling their out-of-pocket payments “nearly unaffordable,” the news release notes. Additionally, one out of five had a gap in coverage during the year.
“Congress, employers, insurers, and healthcare providers all play a role in lowering costs and making care more affordable, so families can avoid debt and get the care they need to stay healthy,” said Sara R. Collins, PhD, lead study author and Commonwealth Fund Senior Scholar and Vice President for Health Care Coverage and Access and Tracking Health System Performance, in the news release.
Astute laboratory managers will look beyond the study’s face value and consider the profound impact such findings could have on their own labs.
“While having health insurance is always better than not having it, the findings challenge the implicit assumption that health insurance in the United States buys affordable access to care,” the Commonwealth Fund said of its 2023 study. This sentiment rings true in the Funds’ latest findings as well.
“The Affordable Care Act has covered 23 million people and cut the uninsured rate in half. But high costs are a serious problem for many Americans, regardless of the kind of insurance they have,” said Sara R. Collins, PhD (above), lead study author and Commonwealth Fund Senior Scholar and Vice President for Health Care Coverage and Access and Tracking Health System Performance, in a news release.

Labs Often Must Collect Payments Upfront
Many patients are in high deductible health plans and may forgo or delay ordered lab tests. Labs collect patient deductibles, copays, and out-of-pocket expenses directly from patients. However, underinsured patients may be required to pay for 100% of the services they receive, requiring the lab to collect these payments upfront.
Underinsured patients already facing a mountain of debt may struggle to pay for lab services. The debt many owe is substantial. “Nearly half (48%) of all adults with medical debt owe $2,000 or more; one of five (21%) carry a staggering $5,000 or more in debt,” Commonwealth Fund noted in its study.
Thus, collecting money owed is proving to be a problem for healthcare providers. Patient collection rates are plummeting to 48%, with “providers writing off more bad debt from patients with insurance,” TechTarget reported.
“Lower patient collection rates left providers facing bad debt. The analysis showed that 1.54% was the bad debt write-offs as a percentage of total claim charges in 2023. Researchers note that the percentage may be small, but the total cash amount equated to over $17.4 billion last year,” TechTarget added.
Having some rather than no insurance is not the safety net for patients previously thought. When it comes to the insured, their debt “accounts for 53% of the estimated $17.4 billion that hospitals, health systems, and medical practices wrote off as bad debts in 2023,” Business Wire noted, citing data from Kodiak Solutions’ quarterly revenue cycle benchmarking report.
Delaying Critical Lab Tests
The challenges the insured face with debt impacts labs in the long run. A staggering 57% of survey respondents reported passing on needed care because they could not afford it, and of those, 41% said their health concerns worsened when they denied themselves that care, Commonwealth Fund noted.
Increasingly poor health means patients might struggle to collect sufficient income to pay for their now added expenses, further causing them to struggle to pay for anything insurance might not cover, such as doctor ordered lab tests.
The affect this has on hospitals and medical laboratories casts light on the healthcare marketplace as a whole. It’s a trend that needs to be further studied.
“Most hospital bad debt is associated with insured patients, and nearly one in three hospitals report over $10M in bad debt,” are two of the top five financial healthcare statistics reported by Definitive Healthcare in a 2023 report.
“Expanding patient collection strategies may be key to maximizing revenue and avoiding losses,” TechTarget suggested.
Possible Solutions
The Commonwealth Fund study made clear that employer-covered healthcare does not guarantee affordable care or that ample care will be provided. Possible solutions from the study called on policymakers to “expand coverage and lower costs for consumers.” It added that “extending enhanced premium tax credits and strengthening protections against medical debt could make coverage more protective and affordable.”
Until a solution can be found, it’s wise to stay abreast of this trend and how it can impact the bottom line of clinical laboratories and anatomic pathology groups nationwide.
Encouraging the next generation of clinical laboratorians could contribute to solving current staffing shortages in the nation’s medical laboratories
This holiday season brings an exciting new gift that will catch the attention of Dark Daily’s readers. It’s a children’s book that introduces young readers to working in clinical laboratories!
“This is a steppingstone into the career of laboratory science, so we should share what we do with the world. Any lab scientist who has a child, niece, nephew, or grandchild in their life should give this gift. It could open an entirely new world of possibilities for them. It could make them excited for science,” said the book’s author Kelli Garcia, microbiology supervisor at Saint Francis Hospital and Medical Center, part of Trinity Health of New England, in an exclusive interview with Dark Daily.
“Most children have a small idea or image of what options are available in medicine or science—usually a doctor or nurse. They never see the people that work behind the scenes or different areas,” Garcia noted.
She penned her book with hopes of calling attention to medical fields beyond those most commonly seen by children, as she also had only learned about the field when she was graduating from college.
“I Want to be a Laboratory Scientist,” is now available at many major retailers, including Amazon and Barnes and Noble. (Graphic copyright: Kelli Garcia.)
Opening Children’s Eyes
Garcia’s journey took about four years from the moment she began writing to finally finding a publisher for her 36-page book that’s geared toward 6-8 year-olds. “I spent many hours writing and rewriting so it wouldn’t be too specific but also not too minimal that the point and purpose would be missed,” she said, adding that her daughter was her muse.
Garcia’s own children have excitedly brought the book to their schools and shared them with their local library. Such steps could help a field that is working hard to keep up with demand.
“There are so many ways to engage children in different areas of science as long as we make those areas known to them. They don’t all wants to be a doctor or nurse, but some still want to help in another way. This book will show them you can be in medicine helping people but behind the scenes—the unsung hero,” microbiologist and children’s book author Kelli Garcia (above) told Dark Daily. She added, “It will also make them aware that laboratory science is a rewarding career and show that it’s not just doctors and nurses who are involved in treating patients.” (Photo copyright: Kelli Garcia.)
Those low numbers are not going unnoticed. The Medical Laboratory Personnel Shortage Relief Act of 2024, introduced in September by State Representative Deborah Ross (NC-02), was created to help bring a much-needed boost to the field. The Act brought in grants for clinical laboratory staff training in accredited institutions and added “medical laboratory professionals to the National Health Service Corps,” the ASCLS noted.
The ASCLS continues to encourage those working in clinical laboratories to make their voices heard on Capitol Hill to further support the field.
Hope is growing that more students will choose clinical laboratory work for their futures. Medical and clinical laboratory technologist was listed in Careers Fittest rankings of the top 14 careers to consider in 2024/2025. Careers Fittest cited an 11% job growth expected in the area by 2031.
It is a worthy objective to educate younger children about the career path of a clinical laboratory scientist and opportunities to work in microbiology laboratories. Perhaps Garcia’s new children’s book will help with that trend, and just in time for the holidays!
Clinical laboratories will need new methods for accommodating the increase in senior patients seeking rapid access to medical laboratory testing and pathology services
Experts within the healthcare industry are predicting existing care delivery models will need to be revised within the next few years to accommodate a rapidly aging population dubbed a “silver tsunami.” Many hospital systems are actively taking steps to prepare for this coming sharp increase in the number of senior citizens needing healthcare services, including clinical laboratory testing.
Multi-hospital health systems will have to accommodate demand for healthcare delivered in ways that meet the changing expectations of seniors. These include rapid access to clinical laboratory testing and anatomic pathology services, electronic health records, and telehealth visits with their doctors.
These trends will also require clinical laboratories to evolve in ways consistent with meeting both the volume of services/testing and improved levels of personal, speedy access to test results that seniors expect.
All of this is problematic given the current state of hospital staff shortages across the nation.
Investopedia defines the term “silver tsunami” as “the demographic shift caused by the increasing number of older adults in society, led by the baby boom generation.”
Baby boomers are individuals who were born between 1946 and 1964. The US Census Bureau estimates there are 76.4 million baby boomers living in the country today, and that by 2030 all boomers will be 65 years of age or older.
“In the next five years, the most significant disruptor to healthcare will be the capacity challenges associated with the ‘silver tsunami’ of baby boomers hitting the age of healthcare consumption,” said Jonathan Washko, MBA, FACPE, NRP, AEMD (above), director at large, National Association of Emergency Medical Technicians (NAEMT) and assistant vice president, CEMS Operations, in an interview with Becker’s Hospital Review. Clinical laboratories will have to engage with these senior patients in new ways that fit their lifestyles. (Photo copyright: EMS1.)
Silver Tsunami Could Transform Healthcare
Approximately 10,000 people turn 65 in the US every day, making them eligible for Medicare. This increase in recipients is likely to strain the government system. Healthcare organizations are seeking new ways to prepare for the anticipated boost in seniors requiring health services.
Washko believes the population shift will cause healthcare leaders to develop novel care models based on “intelligent and intentional design for better outcomes, lower costs, and faster results,” Becker’s Hospital Review reported.
“Solutions will require shifts to care in the home, new operational care models, and technology integration,” Washko noted. “These will allow the medicine being delivered to be effectively and efficiently optimized, vastly improving the productivity of existing and net new capacity.”
A recent HealthStream blog post outlined some of the methods hospitals can use to adapt to an aging population. They include:
Facility Design: Modifying lighting, using large-print signage, providing reading glasses and hearing amplifiers, purchasing taller chairs with arms and lower examination tables.
Technology: Offering assistive devices, creating more telehealth options, developing more user-friendly websites and electronic medical records.
Healthcare Delivery: Training staff on geriatric care, offering services intended for an older population, such as geriatric psychology, fall prevention programs, and establishing a more patient-centered environment.
“Anticipated regulatory challenges post-election will influence healthcare operations. The looming recession may alter how individuals access healthcare and treatment based on affordability,” Shelly Schorer, CFO CommonSpirit Health, told Becker’s Hospital Review. “Despite these headwinds and challenges, at CommonSpirit we are prepared to pivot and meet the changing needs of our communities by accurately predicting and addressing their healthcare needs efficiently.”
“This represents the greatest market disruption on the near-horizon,” said Ryan Nicholas, MD, Chief Quality Officer at Mercy Medical Group. “This has prompted Mercy Medical Group to move rapidly into value-based care with focus on total cost of care and network integrity.”
Nichols told Becker’s Hospital Review that Mercy’s Medicare population has increased by 24% over the last year, and that Mercy is anticipating a growth of 28% over the next year. These increases have convinced the organization to shift its view of service functions and to invest in additional resources that meet the growing demands for senior healthcare.
“Expanding ambulatory services and improving access for primary care services to reduce unnecessary [emergency department] utilization and shorten length of stay is our top priority,” Nichols said.
Shifting Demand for Clinical Laboratory Testing
This is not the first time Dark Daily has covered how shifting demographics are changing the landscape of healthcare services in nations where populations are aging faster than babies are being born.
Thus, many healthcare organizations are taking a proactive approach to the expected increase in seniors needing care for age-related and chronic illnesses.
“This along with other risk and value-based models will continue to drive integration of healthcare services and the value proposition through improving quality while reducing costs,” Alon Weizer, MD, chief medical officer and senior vice president, Mount Sinai Medical Center, Miami Beach, Fla., told Becker’s Hospital Review. “While we are investing heavily to be successful in these models through primary care expansion and technology that will help reduce the need for acute care services, we continue to focus our culture on providing safe and high quality care to our patients.”
Clinical laboratories will need to adapt to the changing needs of older patients to ensure all people receive high quality care. The coming “silver tsunami” will require labs to evolve in ways consistent with meeting the growing needs of seniors and providing better levels of personal services and access to cost-effective, fast, and accurate lab testing.
