U.S. physicians who provide radiation services for cancer patients have a long-running feud with the Centers for Medicare & Medicaid Services over a series of payment rate cuts for their services, but these medical societies are now teaming up to address the issue. These medical societies are making the case that payment reform is not only critical for the future of radiation oncology but are also optimistic that congressional interest in the dilemma has quickened sufficiently to suggest that a congressional response may be on tap in 2024.
Providing the right therapy at the right time has proven more difficult in the world of cancer than in other disease areas thanks to the variability in treatment response, but a new study hints that this problem may be at least partly solved for non-small cell lung cancer (NSCLC). A study presented at this year’s meeting of the American Society for Radiation Oncology (ASTRO) in San Diego shows that circulating tumor DNA (ctDNA) can provide therapeutic guidelines for oligometastatic forms of the disease, including when high-dose radiation therapy may or may not be indicated.
Breakthroughs in early detection of cancer offer increasing hope for better outcomes and longer lives for individuals affected by malignancies. This year’s American Society of Clinical Oncology annual meeting highlighted strong results from several companies at the forefront of this potential transformation.
In the flurry of presentations on early detection of cancer at the 2023 American Society of Clinical Oncology Annual Meeting, Grail LLC stood out for the number of sessions and the strength of its results. In a real-world study presented, Grail’s Galleri multi-cancer early detection (MCED) test cancer signal origin (CSO) demonstrated accuracy of 91%.
Gracell Biotechnologies Inc. is initiating two clinical trials in China in refractory systemic lupus erythematosus for lead candidate GC-012F, a CD19/B-cell maturation antigen dual-targeting CAR T.
The 2023 American Society for Clinical Oncology Annual Meeting featured several notable developments on the diagnostics side, including significant advances in multi-cancer early detection (MCED). Grail Inc. presented its results from SYMPLIFY, the first major study of its MCED test in symptomatic patients. The test showed a negative predictive value of more than 97% and a positive predictive value that exceeded 75% in individuals who presented to primary care with non-specific symptoms that prompted a referral for cancer evaluation.
For a non-invasive cancer, ductal carcinoma in situ (DCIS) has spread rapidly—at least in research studies. Multiple companies presented results of diagnostic tests and genomic analysis that offer guidance for selecting treatment options for stage 0 breast cancer at the 2022 American Society of Clinical Oncology (ASCO) annual meeting, which concluded in Chicago on June 7. Several of these studies reliably predicted which patients can safely be selected for active surveillance without surgery, who would benefit from endocrine or radiotherapy following surgery and who would be best served by risk-reducing surgery such as double mastectomy.
Grail LLC reported a new study with the U.K.’s NHS to assess the clinical utility of its Galleri multi-cancer early detection test (MCED) for reducing late-stage cancer diagnoses. Menlo Park, Calif.-headquartered Grail presented the study design during the American Society of Clinical Oncology (ASCO) meeting in Chicago. The randomized controlled trial will enroll 140,000 asymptomatic participants aged 50-77 living across England to determine if Galleri can find cancers at an early stage when they are less advanced.
Interim phase I data from 16 patients with refractory metastatic uveal melanoma provide a tantalizing hint that Ionctura SA’s phosphoinositide 3-kinase (PI3K) delta inhibitor IOA-244 PI3 may offer a survival benefit. Thirteen of the 16 patients –
81.25% – remained alive and on therapy after 12 months of treatment. All had received one or more prior therapies.
The American Society of Clinical Oncology (ASCO) updated its guidelines to recommend use of Biotheranostics Inc.’ Breast Cancer Index (BCI) molecular gene-expression test to aid decisions on extended endocrine therapy in certain patients with the most common type of breast cancer.
