Social factors may affect survival in lung cancer patients

A recent study found that social factors can significantly affect the survival rates of lung cancer patients, with African Americans facing higher mortality rates due to poorer physical performance and weight loss. The researchers adjusted for these factors in their analysis, finding no difference in outcomes between ethnic groups.

Other highlights in the Feb. 20 issue of JNCI

African-American patients with non-small-cell lung cancer have a significantly lower one-year survival rate compared to non-African-American patients. Despite similar disease stages and health care disparities, researchers found no difference in outcomes after adjusting for factors such as performance status and socioeconomic status.

Raloxifene after tamoxifen not beneficial

Researchers found that raloxifene did not prevent growth of breast tumors previously exposed to tamoxifen, while being less effective in blocking endometrial tumor growth. The study suggests that raloxifene may not further reduce the risk for breast cancer recurrence after five years of tamoxifen therapy.

Raloxifene following tamoxifen may offer no more reduction in breast cancer risk

Researchers found that raloxifene did not further prevent the growth of breast tumors previously exposed to more than 5 years of tamoxifen. Raloxifene also failed to block the growth of endometrial tumors caused by low-dose estrogen, suggesting it may increase endometrial cancer risk.

American Thoracic Society Journal news tips for February (second issue)

Recent studies have shown that low-dose computed tomography can detect lung cancers at an earlier stage than traditional chest radiography. Additionally, research has found a higher incidence of acute lung injury in Australian intensive care units, with lower mortality rates compared to international studies. Furthermore, experts argue...
