When a patient receives a cancer diagnosis, the main focus is to treat the disease. But stopping smoking after a cancer diagnosis is also important because continuing to smoke can negatively affect patients' responses to treatments, their subsequent cancer risk, and, potentially, their survival.
Elyse R. Park, PhD, MPH, of the Massachusetts General Hospital/Harvard Medical School in Boston, led a team that looked to see how many patients quit smoking around the time of a cancer diagnosis, and which smokers were most likely to quit.
The investigators determined smoking rates around the time of diagnosis and five months after diagnosis in 5,338 lung and colorectal cancer patients. At diagnosis, 39 percent of lung cancer patients and 14 percent of colorectal cancer patients were smoking; five months later, 14 percent of lung cancer patients and 9 percent of colorectal cancer patients were still smoking. These results indicate that a substantial minority of cancer patients continue to smoke after being diagnosed. Also, although lung cancer patients have higher rates of smoking at diagnosis and following diagnosis, colorectal cancer patients are less likely to quit smoking following diagnosis.
Factors and characteristics that predicted continued smoking differed by cancer type. Lung cancer patients who continued smoking tended to have Medicare or other public health insurance, have a lower body mass index, have low emotional support, not have received chemotherapy, not have had surgery, have had prior heart disease, and have smoked a high number of cigarettes per day at some point during their lives. Colorectal cancer patients who continued to smoke tended to be male, have completed less education, be uninsured, not have had surgery, and have once smoked a high number of cigarettes per day.
"These findings can help cancer clinicians identify patients who are at risk for smoking and guide tobacco counseling treatment development for cancer patients," said Dr. Park.
In an accompanying editorial, Carolyn Dressler, MD, of the Arkansas Department of Health in Little Rock, noted that Dr. Park's research highlights the critical importance of physicians and other caretakers to address tobacco cessation, particularly at the time of diagnosis. "Most clinicians acknowledge the importance of addressing tobacco cessation in their patients; however, few do it," she wrote. "We know enough now to implement effective cessation programs to identify and help cancer patients quit at the time of diagnosis and support them to prevent relapse. By doing so, we maximize patients' response to therapy, their quality of life, and their longevity."

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
