Targeted Intraoperative Radiotherapy Concurrent With Lumpectomy Noninferior to External-Beam Radiotherapy in Preventing Local Breast Cancer Recurrence
19 November 2013
In a randomized noninferiority trial (TARGIT-A) reported in The Lancet, Jayant S. Vaidya, PhD, and Michael Baum, MD, of University College London, and colleagues compared risk-adapted radiotherapy using single-dose targeted intraoperative radiotherapy vs fractionated external-beam radiotherapy in women with breast cancer. Targeted intraoperative radiotherapy met the noninferiority margin for 5-year local recurrence among all patients and when given concurrently with lumpectomy but not when delayed until after lumpectomy (postpathology). Breast cancer mortality did not differ significantly between the two groups, but targeted intraoperative radiotherapy was associated with reduced non–breast cancer mortality.
Few Benefit From Contralateral Breast Removal, Model ShowsMisconceptions Leading to More Women Choosing Prophylactic Procedure
Misconceptions Leading to More Women Choosing Prophylactic Procedure
Washington—Of the thousands of women with early-stage breast cancer in one breast who opt to undergo a contralateral prophylactic mastectomy every year, less than one in 100 will derive any survival benefit from the procedure, a new computer model suggests.
“We hope that by providing women with accurate and easily understood information about the potential benefits for contralateral prophylactic mastectomy [CPM], this may impact current trends,” said study co-author Pamela Portschy, MD, a surgical resident at the University of Minnesota, Minneapolis.
Strong Showing for Ado-Trastuzumab Emtansine in Advanced HER2-Positive Heavily Pretreated Breast Cancer
15 November 2013
Results of the phase III TH3RESA trial show that the antibody-conjugate ado-trastuzumab emtansine (Kadcyla), formerly known as T-DM1, extends progression-free survival in women with advanced HER2-positive breast cancer that progressed on two or more previous HER2-directed therapies including trastuzumab (Herceptin) and lapatinib (Tykerb). The findings were presented at the European Cancer Congress 2013 in Amsterdam.

The US Food and Drug Administration (FDA) has approved the first drug to be used in early stage breast cancer treatment. Perjeta (pertuzumab) will be used as part of a complete treatment regimen for patients before surgery (neoadjuvant setting).
Breast cancer spread: clues found in molecular switch

Using state of the art technology, researchers at the University of Copenhagen in Denmark have pinpointed molecular mechanisms that they suspect play an important role in breast cancer cell growth and spread (metastasis).
FDA Grants Regular Approval to Crizotinib for ALK-Positive NSCLC
21 November 2013
The U.S. Food and Drug Administration (FDA) today granted regular approval for crizotinib (Xalkori) for the treatment of patients with metastatic non–small cell lung cancer (NSCLC) whose tumors are anaplastic lymphoma kinase (ALK)-positive as detected by an FDA-approved test.
Today’s approval was based on demonstration of superior progression-free survival and overall response rate for crizotinib-treated patients compared to chemotherapy in patients with ALK-positive NSCLC with disease progression after platinum-based doublet chemotherapy.
Crizotinib was previously granted accelerated approval in August 2011 based on durable objective response rates of 50% and 61% in two single-arm, open-label studies.
LUX-Lung 3: Afatinib Prolongs Progression-free Survival vs Cisplatin/Pemetrexed in Advanced Lung Adenocarcinoma
15 August 2013
Afatinib (Gilotrif) is an oral selective ErbB family inhibitor that irreversibly blocks signaling from EGFR/ErbB1, HER2/ErbB2, and ErbB4 and has exhibited broad-spectrum activity against EGFR mutations in preclinical studies. A phase II study of afatinib in EGFR-mutation positive lung adenocarcinoma showed high response rates and progression-free survival.
12-Gene Recurrence Score Independently Predicts Recurrence in Patients With Stage II/III Colon Cancer
22 November 2013
In a study reported in Journal of Clinical Oncology, Greg Yothers, PhD, of the National Surgical Adjuvant Breast and Bowel Project (NSABP) Biostatistical Center and the University of Pittsburgh Graduate School of Public Health, and colleagues assessed performance of the 12-gene colon cancer recurrence score in patients with stage II or III colon cancer who were treated with fluorouracil (5-FU) with or without oxaliplatin. They found that the recurrence score is an independent predictor of recurrence in this setting and that it provides predictive information beyond standard clinical and pathologic risk factors.

FDA approves Sorafenib to treat late stage thyroid cancer
22 November 2013
The U.S. Food and Drug Administration today expanded the approved uses of sorafenib (Nexavar) to treat late-stage differentiated thyroid cancer. The new indication is for patients with locally recurrent or metastatic, progressive differentiated thyroid cancer that no longer responds to radioactive iodine treatment.
New marker for thyroid cancer recurrence identified

High levels of two microRNA molecules within papillary thyroid cancer tumours predict recurrence after surgery, according to new Australian research.
Epigenetic Modification of HAND2 May Be Associated With the Development of Endometrial Cancer
22 November 2013
In a study reported in the journal PLoS One, Allison Jones, MD, of the Elizabeth Garrett Anderson Institute for Women’s Health, University College London, and colleagues analyzed the functional role of epigenetic factors in endometrial cancer development. They found that HAND2 methylation could potentially be employed as a biomarker for early detection of endometrial cancer and as a predictor of treatment response.
Brivanib Studied in First- and Second-Line Therapy for Advanced Hepatocellular Carcinoma
15 November 2013
The investigational drug brivanib is a dual inhibitor of vascular endothelial growth factor and fibroblast growth factor signaling, both implicated in hepatocellular carcinoma. The agent was recently evaluated in two phase III trials, one comparing first-line brivanib with sorafenib (Nexavar) in advanced hepatocellular carcinoma (BRISK-FL trial) and one comparing brivanib plus best supportive care vs placebo plus best supportive care in patients with advanced hepatocellular carcinoma in whom sorafenib therapy failed or was not tolerated (BRISK-PS trial).

ASCO Studies Support Limited Use of 'Routine' Imaging
15 August 2013
The overuse of imaging in oncology workup and surveillance is a timely concern, as health-care dollars shrink and the risk for second malignancies becomes clearer. At this year’s ASCO Annual Meeting, several studies showed that although many routine imaging studies may be unnecessary, physicians can be slow to adopt new recommendations.
