Hello, and welcome to the ASCO Guidelines podcast series. My name is Shannon McKernin. And today, I'm interviewing a panel of authors from "Medication-Related Osteonecrosis of the Jaw: MASCC/ISOO/ASCO Clinical Practice Guideline." So could I have you each introduce yourselves for the listeners today?

Thank you, Shannon. I'm Dr. Deborah Saunders. I'm the president of the International Society of Oral Oncology and was the section head for the Systematic Review on "Medication-Related Osteonecrosis of the Jaw," with MASCC and ISOO. I was a proud part of the steering committee and one of the authors.

Thank you, Debbie. My name is Dr. Douglas Peterson. I am professor of oral medicine in the School of Dental Medicine at the University of Connecticut Health Center in Farmington, Connecticut. I am also a faculty member in the Head and Neck Cancer Oral Oncology Program at the university's Neag Comprehensive Cancer Center. I'm a member of the steering committee for this clinical practice guideline and one of the co-authors as well. In addition, and as of June 2019, I have been serving as chair elect during this next year for ASCO's Clinical Practice Guidelines committee.

Thank you, Doug. My name is Noam Yarom. I'm an all medicine specialist from the Sheba Medical Center in Tel Aviv University in Israel. I'm serving as a culture of this guideline, and it is a pleasure to be with you today.

Thanks, Noam. I am Dr. Charles Shapiro, professor of medicine at the Mt. Sinai Hospital in New York. And I'm co-chair of the guideline "Medical-Related Osteonecrosis of the Jaw." And I'm happy to be here.

Thank you all for being here today to discuss this guideline on the podcast. So first, can you give us a general overview of what this guideline covers.

Sure. So you know, ASCO and MASCC, as well as ISOO decided that it would be great to provide a practical evidence-based approach in a multidisciplinary type setting to address this important topic that impacts all of our professions, that being medication-related osteonecrosis of the jaw. It's terminology and its definition and the path that's varied and even part of this publication identifies the need for us to move forward with a concise definition and similar terminology, that being medication-related osteonecrosis of the jaw. Medication-related osteonecrosis of the jaw is defined as the presence of an exposed or bone that is probable by a probe in a patient that has a history or is undergoing present use of a bone-modifying agent. This being in the absence of any patients having received any radiation to the head and neck and the absence of metastatic lesions to the jaw. The importance of us identifying this definition and agreeing on the terminology allows us to move forward in future publication to better compare outcome and provide better prevention and treatment for our patients moving forward.

And what are the key recommendations of this guideline?

There are six clinical questions associated with this clinical practice guideline as well as a series of recommendations built within each of the clinical questions. Clinical question one is directed to the preferred terminology and definition for osteonecrosis of the jaw, both of the maxilla and the mandible, as associated with pharmacologic therapies in oncology patients. The panel recommends that the term medication-related osteonecrosis of the jaw, MROJ, be used when referring to bone necrosis associated with pharmacologic therapies. As Dr. Saunders has described, the definition contains three key elements-- current or previous treatment with a bone-modifying agent or angiogenic inhibitor, exposed bone, or bone that can be probed through an intra or extra-oral fistula in the maxillofacial region and that has persisted for longer than eight weeks. And third, no history ...

Dr. Supriya Mohile , Dr. William Dale, and Dr. Heidi Klepin discuss the updated guideline on the practical assessment and management of age-associated vulnerabilities in older patients undergoing systemic cancer therapy. They highlight recent evidence that prompted the guideline update, and share the updated evidence-based recommendations from the panel, focusing on geriatric assessment-guided management. Dr. Mohile also reviews what the expert panel recommends should be included within a geriatric assessment, and Dr. Dale highlights the Practical Geriatric Assessment tool, aimed at helping clinicians implement a geriatric assessment. Dr. Klepin comments on the impact for both older adults with cancer and their clinicians, and reviews outstanding questions and challenges in the field.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one at asco.org/podcasts.

My name is Brittany Harvey, and today I'm interviewing Dr. William Dale from City of Hope National Medical Center, Dr. Heidi Klepin from Wake Forest Baptist Comprehensive Cancer Center, and Dr. Supriya Mohile from University of Rochester Medical Center—co-chairs on “Practical Assessment and Management of Vulnerabilities in Older Patients Receiving Systemic Cancer Therapy: ASCO Guideline Update.”

Thank you for being here, Dr. Dale, Dr. Klepin, and Dr. Mohile.

Dr. William Dale: Nice to see you. Thanks for having us.

Brittany Harvey: Then, before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensures that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including our guests joining us on this podcast episode today, are available online with the publication of the guideline in the Journal of Clinical Oncology linked in the show notes.

Diving into the content of this guideline first, Dr. Dale and Dr. Mohile, can you speak to what prompted an update of this ASCO guideline on the practical assessment and management of age-associated vulnerabilities in older patients undergoing systemic cancer therapy, which was previously published in 2018?

Dr. William Dale: Sure. Yes. In 2018, that was the very first guideline for older adults that ASCO had created, and that was based on work that had been done up to that time, focused on chemotherapy toxicities. And to summarize what was put out at that time, the evidence was thought to be strong enough for doing geriatric assessments. And these are specialized assessments across a number of domains, including functional impairments, cognitive losses, social impairments, etc. But to do these kinds of geriatric assessments with validated tools; that a certain selection of these domains to cover everything that was relevant; to conduct non-cancer prognostication so that for decision-making purposes, if someone were to have their cancer cured, what would be their prognosis, and help make decisions about giving chemotherapy and what doses; and then to enact geriatric assessment-guided target interventions was the fourth recommendation. And so that's where we were in 2018.

In 2020 at ASCO, there was an oral session that had four randomized controlled trials that enrolled older adults. And in that was kind of the signal that there was more coming. And in 2021, two big trials that are practice-changing were published. One led by Dr. Mohile in Lancet that we call the GAP70+ stu...

My name is Brittany Harvey and today I am interviewing Dr. Pauline Funchain from Cleveland Clinic in Cleveland, Ohio, author on Systemic Therapy for Melanoma: ASCO Guideline Rapid Recommendation Update. Thank you for being here, Dr. Funchain.

Dr. Pauline Funchain: It's great to be here with you, Brittany. Thank you!

Brittany Harvey: First, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline.

The full conflict of interest information for this guideline panel is available online with the publication of the guideline in the Journal of Clinical Oncology.

Dr. Funchain, do you have any relevant disclosures that are directly related to this guideline topic?

Dr. Pauline Funchain: I do not have relevant disclosures that relate to this guideline topic.

Brittany Harvey: Great, thank you. Then getting into the rapid update, what prompted this rapid update to the Systemic Therapy for Melanoma: ASCO Guideline published in 2020?

Dr. Pauline: So, earlier this year, on January 25th, the FDA approved tebentafusp for metastatic uveal melanoma. So, this is the first FDA approval for metastatic uveal melanoma. We felt it was really important to put out a rapid update to let both clinicians know about the therapy and also so that more patients can get access to it as quickly as possible.

Brittany Harvey: Understood. So, then based on this new FDA approval, what are the updated recommendations for patients with uveal melanoma?

Dr. Pauline Funchain: So, any patients who have a previously untreated metastatic uveal melanoma, and also who are HLA-A*02:01 positive, this group of patients should be offered tebentafusp as systemic therapy.

This is the only systemic therapy that has been shown to prolong overall survival in patients with metastatic uveal melanoma. And if you look at the kind of benefit that was seen, patients who were on tebentafusp had a median overall survival of 21.7 months versus 16 months in comparison to investigator's choice. In this case, that was either single agent pembrolizumab, ipilimumab, or dacarbazine. So, it is a pretty significant overall survival benefit.

Brittany Harvey: Great! Thank you for reviewing those updated recommendations and the data behind them. So, what should clinicians know as they implement this updated recommendation?

Dr. Pauline Funchain: So, they should know that there was a great overall survival benefit seen, but it doesn't correlate with the objective response rate that was seen in the trial. So, for patients who were treated with tebentafusp, the objective response rate was 9%. And for those patients who were treated with the investigator's choice, again, that was single agent pembrolizumab, ipilimumab, or dacarbazine, the response rate was 5%.

So, that margin was not very different in terms of objective response rate when looking at RECIST-based criteria, so radiologic criteria for response, but the survival was clearly seen. And interestingly, even in those patients that had radiologic progression, there was an improved survival for those patients who were on tebentafusp versus investigator's choice.

So, there is some kind of survival benefit that may not correlate with what is seen on imaging. So, clinicians should know that they may not see a dramatic response in terms of tumor size on imaging, but patients may still benefit from the therapy.

Brittany Harvey: Understood. So, then you've just talked a little bit about responses in patients. So, how does this guideline update affect patients with melanoma?

Dr. Pauline Funchain: So, despite a difference in response rate, long story short, there is an overall survival difference. So, really, this is the first overall survival difference that we have seen in metastatic uveal melanoma.

It is really exciting. It is finally an approved drug for metastatic uveal melanoma, which did not have any approved or standard of care, systemic drugs. So, this is a really big win...

My name is Brittany Harvey, and today I'm interviewing Dr. Charles Loprinzi from the Mayo Clinic in Rochester, Minnesota, lead author on prevention and management of chemotherapy-induced peripheral neuropathy in survivors of adult cancers, ASCO guideline update. Thank you for being here, Dr. Loprinzi.

It's my pleasure to participate.

First, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each of our guidelines. The full conflict of interest information for this guideline panel is available online with the publication in the Journal of Clinical Oncology. Dr. Loprinzi, do you have any relevant disclosures that are related to this guideline topic?

Well, that's always the perception, I think. Let me mention a couple of things. I've been intimately involved with research with chemotherapy-induced neuropathy for about 20 years or so, and have looked at a lot of the different drugs and treatments that we considered in this guideline.

I consulted for companies that have interest in neuropathy, including Asahi Kasei Pharma, Disarm Therapeutics, Metis Pharmaceuticals, PledPharma, and NKMax America. But other than that, I do not have anything else to note there.

Great, thanks. So first, what prompted an update to this guideline on the prevention of management of chemotherapy-induced peripheral neuropathy in survivors of adult cancers?

Well, it's been about five years since we did the initial guideline. It is a very prominent problem-- I think probably one of the most prominent chronic problems we get associate with chemotherapy. You get acute problems like nausea and vomiting, but those go away. But this can be a prominent problem that can last for years.

There have been about 40 new trials for looking at prevention of neuropathy while you're giving chemotherapy, or treatment of neuropathy after you receive the chemotherapy and looking at ways to try to treat that. About 40 new trials have been published since we did the last guideline. So it was decided that it's time to look at this again to see what's new, what's not new, and sort things out.

So with that new information that the guideline panel looked at, what are the recommendations for prevention of chemotherapy-induced peripheral neuropathy?

OK. So for prevention-- and we're talking about you're about to give chemotherapy that has neurotoxic properties, if you will. Not all chemotherapies cause neurotoxicity. And by neurotoxicity, I'm talking about numbness, tingling, pain, usually in distal extremities. Hands and feet is where it usually starts. But that's what we're talking about here.

And the bottom line answer, which is similar to what it was five years ago, is that there is no proven means for being able to prevent this problem other than not giving the chemotherapy that can cause the problem. And we usually want to give the chemotherapy to try to kill the cancer process. So there is no proven means.

There is, however, suggestive evidence for a few things. And each of these need more research to really clarify the risks of doing them and that benefits from. One of these things is something called cryotherapy or cold therapy. And you put cold therapy on hands and feet, causes less blood flow, and slows the metabolism somewhat while the person is getting chemotherapy. And there's suggestive evidence that helps, although not proof.

There is another thing that's somewhat related to that, and it's called compression therapy, where if you put tight surgical gloves on a hand while you're getting the chemotherapy, decreasing blood flow when t...

BRITTANY HARVEY: Hello and welcome to the ASCO Guidelines Podcast Series, brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content, and offering enriching insight into the world of cancer care. You can find all the shows, including this one, at podcast.ASCO.org. My name is Brittany Harvey, and today I'm interviewing Dr. Nadine Tung from Beth Israel Deaconess Medical Center in Boston, Massachusetts, and Dr. Dana Zakalik from Beaumont Health in Royal Oak, Michigan, co-chairs of the Management of Hereditary Breast Cancer Guideline Expert Panel and this rapid recommendation update, Adjuvant PARP Inhibitors in Patients With High-Risk Early-Stage HER2-Negative Breast Cancer and Germline BRCA Mutations: ASCO Guideline Recommendation Update. Thank you for being here, Dr. Tung and Dr. Zakalik.

DR. ZAKALIK: Thank you for having us.

DR. TUNG: Thank you so much. Pleasure to be here.

BRITTANY HARVEY: First, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The full conflict of interest information for this guideline panel is available online. Dr. Tung, do you have any relevant disclosures that are directly related to this guideline topic?

DR. TUNG: I do receive research funding from AstraZeneca, as I run a trial using a PARP inhibitor in breast cancer.

BRITTANY HARVEY: Thank you. And Dr. Zakalik, do you have any relevant disclosures?

DR. ZAKALIK: I do not.

BRITTANY HARVEY: Thank you. Then let's get into the meat of this rapid recommendation update. So, Dr. Tung, what prompted this rapid update to a recommendation from the Management of Hereditary Breast Cancer Guideline?

DR. TUNG: The OlympiA Trial, which was presented at ASCO this past June and published the same day in the "New England Journal of Medicine." OlympiA was a large Phase III trial, which demonstrated that a year of adjuvant olaparib, a PARP inhibitor, significantly improved both invasive disease-free survival by nearly 9%, and distant disease-free survival by a similar improvement, in germline BRCA mutation carriers with HER2-negative breast cancer and a high risk of recurrence. Overall survival was numerically better with olaparib, but it didn't yet reach significant improvement as a stringent p-value was required for this early reporting.

And I say early reporting because the trial was reported early after the first event-driven interim analysis showed a benefit with olaparib. 1,800 patients had been enrolled with a median follow up of 2 and 1/2 years at the reporting. But the follow up was 3 and 1/2 years for the first 900 patients enrolled, known as the maturity cohort. And it was comforting that the significant improvement in invasive disease-free survival and distant disease-free survival was also seen when just looking at that maturity cohort. So for those who might think that it's too early and that these benefits might not hold up with longer follow up, it's very comforting that in that maturity cohort with longer follow up, the results were really the same.

And last year, ASCO published guidelines on managing patients with hereditary breast cancer, including women with inherited BRCA mutations, meaning a pathogenic or likely pathogenic variant. At that time, PARP inhibitors were recommended only for BRCA carriers with metastatic disease, based on the OlympiAD and EMBRACE trials. So when OlympiA was published, we felt the need to update the guidelines to recommend olaparib in the early-stage setting for some germline BRCA carriers.

BRITTANY HARVEY: So then, based off this new data from the OlympiA trial, Dr. Zakalik, what is the updated recommendation from the guideline expert panel?

DR. ZAKALIK: The updated recommendation states that for patients with early-stage, ...
