Elective neck dissection of node-negative early-stage oral cancer at the time of primary surgery improves overall survival and disease-free survival compared with therapeutic neck dissection (ie, therapeutic neck dissection at the time of nodal relapse, or “watch and wait” approach), according to a ...
This combination [lenvatinib and everolimus] is a potential game-changer in metastatic renal cell carcinoma. We’ve studied other combinations to no avail; for example, bevacizumab [Avastin] plus everolimus had no advantage over everolimus alone. Other combinations are too toxic, such as sunitinib...
The combination of lenvatinib (Lenvima) plus everolimus (Afinitor) significantly extended progression-free survival compared with everolimus alone in metastatic renal cell carcinoma, according to a randomized phase II trial.1 Median progression-free survival for patients who received the...
“This is an important study. We’ve known for some time that the aromatase inhibitors tend to be better than tamoxifen for postmenopausal women with hormonally sensitive invasive breast cancer. The NSABP B-35 trial asked the same question in ductal carcinoma in situ. These data, which now follow...
Anastrozole was found to be at least as safe and effective as tamoxifen in preventing breast cancer recurrence in women with ductal carcinoma in situ, in the large NSABP B-35/SWOG-35 study.1 Among all women in the trial, however, the 10-year breast cancer–free interval rates were higher in women...

Two immunotherapy agents show promise in preliminary studies of advanced urothelial bladder cancer: the anti–PD-1 (programmed cell death protein 1) antibody pembrolizumab (Keytruda) and the anti–PD-L1 (programmed cell death ligand 1) antibody atezolizumab. Separate phase I studies of each drug...
Jeremy Abramson, MD, Clinical Director of the Center for Lymphoma at Massachusetts General Hospital, Boston, agrees that obinutuzumab is an advance over rituximab. Like rituximab, obinutuzumab targets CD-20, but rituximab does not directly induce cell death. Obinutuzumab is a type 2 antibody and...
The addition of obinutuzumab (Gazyva) to standard bendamustine (Treanda) chemotherapy followed by obinutuzumab maintenance therapy delays the progression of indolent non-Hodgkin lymphoma (NHL), almost doubling progression-free survival in rituximab (Rituxan)-refractory patients, according to the...
Early data on immunotherapy for small cell lung cancer (SCLC) have been encouraging. SCLC may catch up to non–small cell lung cancer (NSCLC), where immunotherapy is now standard of care, if these early data are borne out in phase III trials. Phase Ib and II studies of immunotherapy in SCLC were...
The newer targeted therapies and immunotherapies have proven to be a boon to the treatment of lung and other cancers, but how best to deploy those therapies remains a burning question. Another important focus of current research is the identification and validation of biomarkers for these...

Frederic Amant, MD, PhD, Assistant Professor, Staff Gynecologic Oncologist, and Head of the Scientific Section of Gynecologic Oncology at University Hospitals Leuven in Leuven, Belgium, stressed that the study by Lambertini et al is a meta-analysis, not a randomized controlled trial. Nevertheless,...
Several studies have addressed the risks and benefits of ovarian suppression during chemotherapy for breast cancer in women of childbearing age. A new meta-analysis of randomized trials found that it prevented premature ovarian failure and was associated with a higher number of pregnancies post...
We have made major progress by moving docetaxel forward, and now the largest pool of patients who become hormone resistant have received local therapy and then progressed. We have a lot of drugs for castration-resistant prostate cancer, and we are studying them earlier in the course of disease, but ...
Despite the proliferation of new drugs to treat prostate cancer, further progress is proving somewhat elusive, according to three trials presented at the 2015 European Cancer Congress. One study had positive results with orteronel maintenance therapy in patients with metastatic castration-resistant ...
Anita Mahajan, MD, a radiation oncologist at the University of Texas MD Anderson Cancer Center, Houston, moderated the press conference where these findings were discussed. “Use of radiation for atypical meningiomas has been controversial. It has been difficult to put a study together, because we...
Management of the vast majority of meningiomas is straightforward, but treatment of atypical meningiomas has been controversial. Should radiation be part of therapy or not has been the question. The first analysis of Radiation Therapy Oncology Group (RTOG) 0539 suggested that patients will have...
You don’t need high-tech interventions to prove value. Sometimes we can use a medication that has been around a long time,” declared press conference moderator Brian D. Kavanagh, MD, MPH, FASTRO, of the University of Colorado, Anschutz Medical Campus, Denver. “It is better to prevent the problem of ...
Bone is a common site of metastasis for prostate, breast, and lung cancers, and palliative radiotherapy is often used to treat these metastases. Although it is an effective therapy, severe pain flare following radiation occurs in about one-third of patients. It usually resolves within 10 days, but...
At a press conference held during the ASTRO Annual Meeting, ASTRO President-Elect Brian D. Kavanagh, MD, MPH, FASTRO, interim Chair of Radiation Oncology at the University of Colorado, Anschutz Medical Campus, Denver, said, “This study provides an important lesson for the field. We are lucky to...

HPV-associated oropharyngeal cancer is becoming more and more prevalent. This is a ‘different beast’—distinct from the squamous cell carcinomas of the tonsil and tongue that arise from standard risk factors of tobacco and alcohol. Patients without a smoking history have an 85% to 90% cure rate,...
A new study shows that deintensification of chemoradiation therapy translates to excellent pathologic complete response rates in low-risk human papillomavirus (HPV)-associated oropharyngeal cancer.1 Patient-reported outcomes showed that side effects declined after 8 weeks. The hope is that these...
This study pushes the envelope of how to use our therapies to give the most benefit to patients we otherwise wouldn’t be treating: in this case, children under the age of 3. This age group has historically been a ‘no man’s land.’ Now we see we can treat children as young as 1 year,” said Anita...
The good news is that children as young as 1 year old with the aggressive brain tumor ependymoma can be treated safely and effectively with immediate postoperative radiation therapy, according to the results of a trial presented at the 2015 ASTRO Annual Meeting.1 “Ependymoma is the third most...
In an interview with The ASCO Post, incoming ASTRO President David Beyer, MD, provided his perspective on the use of hypofractionation in prostate cancer.
