Better survival rates seen with lumpectomy compared with mastectomy for early breast cancer

28.01.2013
A new analysis has found that lumpectomy plus radiation for early breast cancer may provide patients with a better chance of survival than mastectomy.

Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the results provide confidence in the efficacy of breast-conserving treatments even among patients with aggressive, early disease.

Lumpectomy combined with radiation is a good treatment choice for women with early breast cancer; however, over the past 10 years, a growing number of women have been choosing mastectomy even for very small cancers. In certain populations—such as women who are young and those living in urban areas with high socioeconomic status—this trend has been most pronounced due to the perception that outcomes may be better with mastectomy than with lumpectomy.

Shelley Hwang MD, MPH, of the Duke Cancer Institute, and her colleagues looked to see whether some populations of women do in fact have better outcomes after mastectomy compared with lumpectomy and radiation. The researchers obtained information regarding all women who were diagnosed in the state of California with stage I or II breast cancer between 1990 and 2004 and who were treated with either mastectomy or lumpectomy plus radiation. The investigators followed 112,154 cases through 2009, and they looked for patterns among different age groups and across different breast cancer types.

In the first three years after surgery, women who underwent mastectomy had a higher risk of dying from heart disease and other diseases than women who underwent lumpectomy, possibly indicating that the latter group was generally healthier, according to Dr. Hwang. Over the entire study period, women were more likely to survive breast cancer after undergoing lumpectomy plus radiation than mastectomy. This was true among all age groups and cancer types, with the biggest benefit seen in women over 50 years of age with hormone-sensitive breast cancer. These women had a 14 percent decreased risk of dying from breast cancer during the study compared with their counterparts who underwent mastectomy.

"The findings in this study should reassure women that among all age groups and tumor types, lumpectomy continues to be an excellent choice for women with small early breast cancers," said Dr. Hwang.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
