“Adjuvant therapy for melanoma to lower the risk of disease recurrence and death in patients with high-risk disease who have undergone definitive surgical treatment has previously been administered primarily to patients with stage III disease, as well as a small group of patients with stage IV disease who could be rendered disease free surgically, according to Ahmad A. Tarhini, MD, PhD.
“These patients have unmet treatment needs. Tarhini, director, Melanoma and Skin Cancer Program and Center for Immuno- Oncology Research, Cleveland Clinic Taussig Cancer Institute, said that toxicities, negative effects on quality of life (QoL), and inconvenient dosing schedules have contributed to the lack of uptake of adjuvant therapy for patients with melanoma.”

After a diagnosis of early stage, hormone-positive breast cancer, you may find yourself facing several daunting decisions, such as choosing between the extensive surgery of mastectomy versus a more minor lumpectomy procedure paired with radiation (with all its challenging side effects). And once surgery is complete, what next? Hormone therapy is clearly indicated for many women, but which drug, and how long to take it? And what about chemo—how to know if the tough side effects are worth the possible reduction in risk of recurrence?
Fortunately, there are a wealth of quality datasets available to inform these decisions. Below are some of the questions we get most frequently from patients using our ASK Cancer Commons service, answered according to the latest thinking from scientific literature and our expert physician network. If you are facing your own cancer treatment decisions and would like free one-one-one expert support, please submit your case here.
1. If my doctor has said either mastectomy or lumpectomy plus radiation are appropriate for me, how do I choose?
Many studies have looked at this, and overall the outcomes for mastectomy versus lumpectomy plus radiation are extremely similar (both are effective treatments, so you can instead weigh the side effects of radiation versus the more intensive surgery of the mastectomy). This webpage provides a helpful summary of the pros and cons of mastectomy compared to lumpectomy.Continue reading…
“A new study finds that more than half of women with early stage breast cancer considered an aggressive type of surgery to remove both breasts. The way women generally approach big decisions, combined with their values, impacts what breast cancer treatment they consider, the study also found.
“Contralateral prophylactic mastectomy – a procedure to remove both breasts when cancer occurs in only one breast – has become increasingly popular in recent years, with more than 20 percent of patients opting for it. For most women, removing the unaffected breast does not improve survival.”
“Most cancer-related deaths are the result of post-surgical metastatic recurrence. In metastasis, cells of primary tumors travel to other parts of the body, where they often proliferate into inoperable, ultimately fatal growths.
“A new Tel Aviv University study finds that a specific drug regimen administered prior to and after surgery significantly reduces the risk of post-surgical cancer recurrence. These medications, a combination of a beta blocker (which relieves stress and high blood pressure) and an anti-inflammatory, may also improve the long-term survival rates of patients. The treatment is safe, inexpensive—two medications similar in price to aspirin—and easily administered to patients without contraindications.”
“Of the women who carry the mutated BRCA1/2 genes, 45-65 percent will develop breast cancer, and 15-39 percent will develop ovarian cancer in their lifetimes. Many women, especially those who have experienced the death of family members to these cancers, elect to undergo preventive surgeries that can significantly increase life expectancy, but require extensive recovery time and can impact later fertility and quality-of-life. However, few guidelines exist that shed light on the optimal age to undergo these procedures, and in what sequence. A new study in the INFORMS journal Decision Analysis provides insight to help enable physicians and patients make better-informed choices.
“The study, ‘Was Angelina Jolie Right? Optimizing Cancer Prevention Strategies Among BRCA Mutation Carriers,’ was conducted by Eike Nohdurft and Stefan Spinler of the Otto Beisheim School of Management, and Elisa Long, of the UCLA Anderson School of Management.”
“The largest and longest trial to compare treatment options for prostate cancer has found little difference in outcomes between men who underwent surgery vs. those who were simply observed by their doctors.
“Led by a researcher at the Minneapolis VA Medical Center, the 20-year national study provides the best evidence yet that most men can live with their prostate cancers, avoiding the potential risks of surgery. The results, though, did show that surgery was probably a better option for younger men with long life expectancies, and some urologists dispute the findings.”
“Researchers presenting a preclinical study at the 2017 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) demonstrated the efficacy and optimal dose for targeted photodynamic therapy (tPDT) to treat prostate cancer before and during surgery. Prostate-specific membrane antigen (PSMA) was targeted with an anti-PSMA antibody radiolabeled with the tracer indium-111 (111In) and coupled with specialized photosensitizers that cause cell destruction upon exposure to near-infrared (NIR). The combined formula is 111In-DTPA-D2B-IRDye700DX.
” ‘Coupling the photosensitizer to an imaging agent that targets PSMA on the tumor surface makes it possible to selectively and effectively destroy prostate tumor remnants and micrometastases while surrounding healthy tissues remain unaffected,’ said Susanne Lütje, MD, PhD, lead author of the study from the Department of Radiology and Nuclear Medicine at Radboud University Medical Center in Nijmegen, the Netherlands, and the Clinic for Nuclear Medicine at University Hospital Essen, Germany.”
“Patients who receive the standard surgical treatment for melanoma that has spread to one or more key lymph nodes do not live longer, a major new study shows.
“The study, published today in The New England Journal of Medicine, found that immediately removing and performing biopsies on all lymph nodes located near the original tumor, a procedure called completion lymph node dissection, did not result in increased overall survival rates.”
