The news is good from the longest follow-up survival study of patients with advanced melanoma who were treated with the anti–programmed cell death protein 1 (PD-1) agent nivolumab (Opdivo).1 Thirty-four percent of patients who received the drug in a phase I trial (CA909-003) were alive 5 years...
Carlos Arteaga, MD, of Vanderbilt-Ingram Cancer Center, Nashville, Tennessee, said, “Breast-conserving therapy is the right thing to do. This study will not change current practice guidelines. Mastectomy is generally reserved for larger tumors and those with multifocal disease. The study just...
Breast-conserving therapy (lumpectomy plus radiation therapy) appears to improve 10-year overall survival for women with early breast cancer compared with mastectomy, according to a very large population-based study from the Netherlands.1 However, the study raises more questions than it answers,...
“We used to consider HER2-positive breast cancer one of the more aggressive forms of the disease. Now we have treatments based on HER2 expression that have dramatically altered the course of the disease for many patients,” said C. Kent Osborne, MD, who moderated the press conference where these...
Ado-trastuzumab emtansine (formerly T-DM1; Kadcyla) improved overall survival compared with treatment of physician’s choice of therapy for patients with pretreated HER2-positive metastatic breast cancer, according to the phase III TH3RESA trial.1 Patients enrolled in the trial had previously been...
Formal discussant of these trials Daniel Hamstra, MD, of Texas Center for Proton Therapy, Irving, offered his perspective. With increased doses of radiation using additional conventional fractions, tumor control is improved, but the risk of damage to normal tissue is increased. Hypofractionation is ...
Separate phase III trials presented at the 2016 Genitourinary Cancers Symposium demonstrated that modest hypofractionated radiotherapy is noninferior to conventional radiotherapy for men with intermediate- and low-risk prostate cancer and should be considered a new standard of care.1,2 However, it...
The Egyptian study presented by Brian Baumann, MD, of the University of Pennsylvania, Philadelphia, was a “valiant effort” to determine whether sequential adjuvant chemotherapy added to adjuvant radiation would improve disease-free survival, said formal discussant of this trial Elizabeth Plimack,...
Adjuvant sequential chemotherapy plus radiation therapy and adjuvant radiation therapy alone significantly improved local tumor control compared with adjuvant chemotherapy alone in locally advanced bladder cancer but the improvement in disease-free survival (3-year disease-free survival of 68% vs...
African Americans who develop metastatic renal cell carcinoma have had worse survival historically than whites. With the advent of targeted therapy, the hope is that the gap in survival would be narrowed. However, a new study has shown that survival for African Americans with metastatic renal cell...
The use of prostate-specific antigen (PSA) screening has led to a dramatic rise in the number of men diagnosed with low-grade prostate cancer. Active surveillance is recommended to manage patients with favorable-risk, low-grade prostate cancer, with the goal of avoiding overtreatment of these...
“This platform has no selection bias. Phlebotomy samples are drawn at key decision points. We begin to see that heterogeneity of circulating tumor cells predicted for shorter progression and survival times with selected androgen receptor–directed therapies. We need to study this prospectively,”...
An early study showed that an experimental blood test (ie, “liquid biopsy”) that characterizes the phenotype and genomic characteristics of circulating tumor cells appears to have utility in personalizing treatment decisions for individual men with advanced prostate cancer.1 The assay—developed and ...
These data will help us personalize treatment for our patients. We still don’t know which women with a favorable cancer like ductal carcinoma in situ are most likely to progress. This is an unmet need,” said C. Kent Osborne, MD, Director of the Dan L. Duncan Cancer Center at Baylor College of...
Ductal carcinoma in situ is a relatively benign form of breast cancer (stage 0), yet up to 10% of women with ductal carcinoma in situ will have a recurrence within 10 years. At present, there is no way to identify which women will recur, so standard treatment is lumpectomy plus radiation therapy....
Formal discussant of this trial William Y. Kim, MD, of the University of North Carolina’s Lineberger Comprehensive Cancer Center, Chapel Hill, commented on the fact that the IMvigor study had a substantial number of patients compared with other phase II trials in bladder cancer. “This trial was not ...
Atezolizumab achieved excellent results in a cohort of patients with platinum-resistant urothelial cancer enrolled in a large phase II trial known as IMvigor 210.1 Overall response rates were greatly improved over those with historical controls, and responses were durable. Although expression of...
Commenting on both of these studies, Christian K. Kollmannsberger, MD, of the British Columbia Cancer Center, Vancouver, Canada, said: “These studies suggest a more personalized approach to testicular cancer. Clearly, we need to do better than traditional risk factors used to guide therapy for...
Although patients with poor-risk metastatic testicular germ cell tumors continue to have less favorable outcomes, the bar has been raised by contemporary treatment. There is still room for improvement in managing metastatic testicular germ cell tumors, especially in poor-risk patients, but if...
Options for second-line therapy of advanced/metastatic renal cell carcinoma are expanding. Updates from the CheckMate 025 and METEOR trials presented at the 2016 Genitourinary Cancers Symposium solidify the value of both nivolumab (Opdivo, an immune checkpoint inhibitor) and cabozantinib...
Investigators are looking at biomarkers to predict the probability of cytokine-release syndrome [in patients receiving chimeric antigen receptor–modified T-cell (CAR-T) therapy] so that they can intervene early. This study [from the University of Pennsylvania] identified two biomarkers that appear...

For the most part, the cardiotoxicity with trastuzumab appears to be largely reversible, unlike anthracyclines, which cause permanent cardiac damage,” said Lisa Carey, MD, Distinguished Professor at the UNC Lineberger Breast Center, Chapel Hill, North Carolina. “In this small study, they saw no...
The beta-blocker bisoprolol was able to prevent trastuzumab (Herceptin)-associated declines in left-ventricular ejection fraction, whereas the effect of the angiotensin-converting–enzyme (ACE) inhibitor perindopril was less robust. Use of bisoprolol reduced dose interruptions for trastuzumab due to ...
This study confirms that what is important is a negative margin, not the margin size,” said Kevin S. Hughes, MD, a breast surgeon who is Co-Director of the Avon Comprehensive Breast Evaluation Center at Massachusetts General Hospital, Boston. “This is a confirmatory study of the consensus...
The width of the surgical margin doesn’t matter, as long as the margin is negative, according to a large study of breast-conserving surgery in patients with invasive breast cancer. The risk of ipsilateral breast tumor recurrence was similar for wide negative margins (2–4 mm) or narrow negative...
Commenting on the AALL03N1 study, press conference moderator Mark Crowther, MD, of McMaster University, Hamilton, Ontario, Canada, said: “This study is extremely important. We have many presentations on new and novel therapies that are expensive, complex, and revolutionary. But if patients don’t...
Mercaptopurine is critical for maintaining remission in childhood acute lymphoblastic leukemia (ALL). However, a study has shown that overreporting of intake is common, and self-reports of intake are not as reliable as electronic reporting.1 About 86% of parents and children overreported the number ...
Press briefing moderator George Daley, MD, PhD, of Boston Children’s Hospital, was enthusiastic about these results, despite the small number of patients treated in studies of CAR-T cells thus far. Most of the results have been in a positive direction, he noted. “It is remarkably exciting to see...
The approach of using genetically engineered chimeric antigen receptor (CAR)-T cells has received much attention for treating leukemias, where it has achieved spectacular long-lasting complete remissions in some patients with no other treatment options. CAR-T cells are also being studied in...
