Quality of Life Is What’s Most Important to Me
For me, getting a cancer diagnosis has been more annoying than frightening. Mainly, I’m annoyed at myself for not taking care of an anal skin tag sooner. (I’d had it since birth.) The growth hadn’t been a problem until I got pregnant with my first child and it became temporarily engorged with...
SIDEBAR: Expect Questions from Your Patients: Cervical Cancer Screening Guidelines
Changes in the cervical cancer screening guidelines, as recommended by the U.S. Preventive Services Task Force (USPSTF), mainly concern longer intervals between screening tests and recommended ages when women should start and stop being screened.

Chemoradiation with Fluorouracil and Mitomycin Reduces Recurrence of Muscle-invasive Bladder Cancer
Radiotherapy is an alternative to surgery in muscle-invasive bladder cancer, particularly in less-fit patients. However, it is associated with high rates of incomplete response or recurrence, with salvage surgery often being required. Although synchronous chemoradiotherapy has improved local...
New Research Shows Promise in Cachexia, a Persistent Clinical Challenge
In the late 1980s, researchers led by Alfred L. Goldberg, PhD, first isolated the large protein complexes now called 26S proteasomes, which are the sites where most cellular proteins are degraded back to amino acids. Protein degradation by the proteasome pathway is critical in regulating many...

The Semantics of Palliative Care
The interview with Thomas J. Smith, MD (The ASCO Post, April 15, 2012), the lead author of the ASCO Palliative Care Provisional Clinical Opinion, was timely. However, it left many clinical terms and issues unclear. A significant percentage of modern medicine, including cancer care, is palliative....
Pretreatment Tumor Hypoxia Predicts Biochemical Failure after Radiotherapy for Prostate Cancer
Hypoxia often occurs early in solid tumor development as a result of imbalances between oxygen supply and consumption and may lead to genetic and molecular signaling that influences the biology and clinical behavior of tumors and response to treatment. Milosevic and colleagues from Princess...
Surviving the Aftermath of Cancer
With medical information now just a click away, it’s difficult to imagine a time before the Internet existed, when finding answers to questions about serious diseases was nearly impossible.
