“As the summer draws to a close, it’s time to start putting away flip-flops, bathing suits and beach bags. But as the seasonal supplies disappear into the back of the closet, sunscreen should stay within arm’s reach for year-round protection against the sun’s ultraviolet rays.
“Because exposure to those harmful UV rays can increase one’s risk of skin cancer — and people spend a lot of time in the sun during the summer — the end of the season is also a good time to perform a skin self-exam. While it’s important to look for any suspicious spots on the skin, research published in the Journal of the American Academy of Dermatology indicates that it’s vital to check for new growths in order to detect melanoma, the deadliest form of skin cancer.”
“The combination of the programmed death receptor 1 (PD-1) inhibitor nivolumab at a reduced dose (1 mg/kg) with the cytotoxic T-lymphocyte antigen 4 (CTLA-4) inhibitor ipilimumab at standard dose (3 mg/kg) for four doses followed by standard-dose nivolumab alone is a standard of care for patients with advanced, previously untreated melanoma. This is based on results from the phase III CheckMate-067 trial that confirmed combination therapy is significantly more effective than single-agent nivolumab or ipilimumab. However, improvement in efficacy is associated with increased treatment-related grade 3/4 adverse events and treatment discontinuation in nearly 40% of patients.”
“With the arrival of two revolutionary treatment strategies, immunotherapy and personalized medicine, cancer researchers have found new hope — and a problem that is perhaps unprecedented in medical research.
“There are too many experimental cancer drugs in too many clinical trials, and not enough patients to test them on.
“The logjam is caused partly by companies hoping to rush profitable new cancer drugs to market, and partly by the nature of these therapies, which can be spectacularly effective but only in select patients.”
“Patients who choose to receive alternative therapy as treatment for curable cancers instead of conventional cancer treatment have a higher risk of death, according to researchers from the Cancer Outcomes, Public Policy and Effectiveness Research (COPPER) Center at Yale School of Medicine and Yale Cancer Center. The findings were reported online by the Journal of the National Cancer Institute.
“There is increasing interest by patients and families in pursuing alternative medicine as opposed to conventional cancer treatment. This trend has created a difficult situation for patients and providers. Although it is widely believed that conventional cancer treatment will provide the greatest chance at cure, there is limited research evaluating the effectiveness of alternative medicine for cancer.”
“When approved therapies don’t work, or stop working, for people with serious or life-threatening illnesses, it puts them in a difficult position. Some turn to clinical trials that are testing experimental treatments. But many can’t do that because they are too sick, don’t meet the requirements of the trial, or can’t afford to travel to the site of a trial. That doesn’t mean they are out of options.”
“Whether a melanoma patient will better respond to a single immunotherapy drug or two in combination depends on the abundance of certain white blood cells within their tumors, according to a new study conducted by UC San Francisco researchers joined by physicians from UCSF Health. The findings provide a novel predictive biomarker to identify patients who are most likely to respond well to a combination of immunotherapy drugs known as checkpoint inhibitors—and to protect those who won’t respond from potentially adverse side effects of combination treatment.
” ‘Combination immunotherapy is super-expensive and very toxic,’ said Adil Daud, MD, director of Melanoma Clinical Research at the UCSF Helen Diller Family Comprehensive Cancer Center and senior author of the new study. ‘You’re putting patients at a lot of extra risk if they don’t need it, and you can adjust for that risk by knowing in advance who can benefit.’ ”
“Many patients with melanoma need a sentinel-lymph-node biopsy to determine if cancer cells have spread there, but a positive finding doesn’t mean all the lymph nodes in the area must be removed, according to new international study.
“Many patients with melanoma need a sentinel-lymph-node biopsy to determine if cancer cells have spread there, but a positive finding doesn’t mean all the lymph nodes in the area must be removed, according to a new international study conducted in part by researchers in Utah that may change standard treatment for melanoma patients whose cancer has spread.”
“The addition of T-VEC (T-VEC; Imlygic), a herpes simplex virus 1-based oncolytic virus, to CTLA-4 inhibitor ipilimumab (Yervoy) improves the objective response rate (ORR) in patients with unresected stage IIIb to IV melanoma, according to findings presented at the 7th European Post-Chicago Melanoma/Skin Cancer Meeting.
“T-VEC was the first approved oncolytic virus therapy in Europe, the United States, and Australia, and its efficacy was previously demonstrated in a phase III trial comprising patients with advanced unresectable melanoma.”
“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.”
