“Vemurafenib offered numerical improvement in disease-free survival in a study of patients with completely resected stage IIC to IIIC BRAF V600 mutation–positive melanoma, but the results did not reach statistical significance. The benefit was bigger in those with stage IIC to IIIB disease, but this should be considered exploratory at this point.
” ‘Despite full resection, patients with stage IIC to III melanoma remain at high risk for disease recurrence and death,’ wrote study authors led by Michele Maio, MD, of University Hospital of Siena in Italy. ‘This situation warrants the use of adjuvant approaches to improve clinical outcomes.’ ”
“The U.S. Food and Drug Administration today approved Imfinzi (durvalumab) for the treatment of patients with stage III non-small cell lung cancer (NSCLC) whose tumors are not able to be surgically removed (unresectable) and whose cancer has not progressed after treatment with chemotherapy and radiation (chemoradiation).”
“Wilmot Cancer Institute patients with advanced melanoma (stage III) now have more options for treatment, thanks to research co-authored by a University of Rochester Medical Center surgical oncologist and published in The Lancet Oncology.
“The study involved comparing two treatment approaches for high-risk melanoma patients with a BRAF gene mutation in their cancer: standard care, which calls for upfront surgery, or giving a two-drug, targeted therapy regimen before surgery and again afterward. Patients in the latter group had longer disease-free survival in the Phase 2 trial, and after seven months researchers halted the study earlier than expected due to the positive results.”

“A pair of targeted therapies given before and after surgery for melanoma produced at least a six-fold increase in time to progression compared to standard-of-care surgery for patients with stage 3 disease, researchers at The University of Texas MD Anderson Cancer Center report in Lancet Oncology. Patients who had no sign of disease at surgery after combination treatment did not progress to metastasis.
“Early results of the study comparing surgery to pre- and post-surgical treatment with the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib were so strikingly positive that MD Anderson’s data safety monitoring board ordered the randomized, prospective phase II trial halted and changed to a single-arm using the combination.”
“Nearly two-thirds of older patients with stage III lung cancer do not receive any treatment, according to a new study.
“Although more than one-third of new lung cancers are diagnosed in patients age 75 years and older, elderly patients may not receive standard-of-care therapy for lung cancer—concurrent chemotherapy and radiation—due to their age, concerns about fragility, less willingness of patients to pursue aggressive therapy, or concerns over the usefulness of therapy for patients with competing risk factors.”
“The future of adjuvant ipilimumab (Yervoy, Bristol-Myers Squibb) for the treatment of resected stage III melanoma could be in doubt, as a combination of ‘astronomically high’ costs and better outcome data with another treatment threaten its position as the standard of care, argues an expert.
“Ipilimumab, a monoclonal antibody that blocks CTLA-4, was shown to significantly improve recurrence-free and overall survival vs placebo when used after surgery. These data, from the EORTC 18071 trial, led to its approval by the US Food and Drug Administration (FDA) as an adjuvant therapy for patients with stage III melanoma in October 2015. This extended its original approval in 2011 to treat late-stage melanoma in patients who are not candidates for surgery.”

“Long-term results of a phase III clinical trial indicate that survival rates for patients receiving chemoradiation for unresectable, locally advanced non-small cell lung cancer (NSCLC) may be more than twice as high as previous estimates. At five years following treatment with a standard dose of 60 Gray (Gy) radiation delivered in 30 fractions, the overall survival rate was 32 percent, setting a new benchmark of survival for patients with inoperable stage III NSCLC. The trial, RTOG 0617, also confirms that a standard dose of radiation therapy is preferable to a higher dose and that cetuximab offers no additional survival benefit for these patients. Findings will be presented today at the 59th Annual Meeting of the American Society for Radiation Oncology (ASTRO) in San Diego.”
“The use of proton beam radiotherapy and concurrent chemotherapy may improve clinical outcomes for patients with inoperable stage III non-small cell lung cancer (NSCLC), while reducing the toxic effects of treatment, researchers from MD Anderson Cancer Center have found.
“The researchers, led by Joe Y. Chang, MD, PhD, reported that the median overall survival of 26.5 months observed in their study ‘was encouraging, and in accord with our original statistical goal of 24 months.’ ”
“Bristol-Myers got a much-needed boost with the earlier-than-expected news that Opdivo beat out Yervoy in a Phase III study focused on a particular niche for adjuvant melanoma therapy. And an analyst who’s been following the data says it could be worth a billion dollars in added annual sales.
“The big biotech says an interim analysis of Checkmate-238 provided researchers with proof that the PD-1 drug outperformed Yervoy, Bristol-Myers’ CTLA-4 drug, among advanced Stage IIIb or IV patients, cutting the recurrence rate for those who have undergone surgery. There are no bottom line numbers in the statement, but Bristol-Myers says they’ll be able to release data at an upcoming conference to show that Opdivo provided a significantly lower risk of disease recurrence.”
