A recent study found that individuals with mental illness are at a higher risk of developing brain and lung cancers. The research, supported by the American Cancer Society and National Institute of Mental Health, suggests that people with mental health problems smoke more than the general population.
Researchers found RFA improves quality of life for inoperable lung cancer patients, with complete ablations resulting in tumor size reduction and minimal enhancement on follow-up CT. Pattern enhancement and changes in tumor size are key indicators of successful RFA on CT.

Physicians often recommend more frequent surveillance colonoscopies than recommended guidelines, citing clinical evidence and personal factors as influential. This may lead to unnecessary procedures, affecting quality of care and resource utilization.
The Hyperspectral Imaging Endoscope (HSIE) system uses spectral images to detect cancerous cells without removing tissue, offering a non-contact method of gaining information about an area. The system achieved good correlations with pathologists' diagnoses and could guide biopsy or establish true diagnostic value in future stages.
Researchers found that black patients are more likely to receive care from physicians who report inadequate access to high-quality diagnostic imaging, sub-specialists, and other essential resources. This disparity in care may be driven by differences in the physicians' access to local services and specialists.
A new study found that Akt pathway activation is associated with better response rates and reduced disease progression in lung cancer patients treated with gefitinib. The researchers identified P-Akt positivity as a key marker for predicting patient response, but not P-MAPK positivity.

The study found that Tarceva significantly improved overall survival and progression-free survival in patients with advanced NSCLC, with a median survival of 6.7 months compared to 4.7 months in the placebo arm. The treatment also showed improvements in time to symptom deterioration, response rate, and patient survival at one year.

Researchers found a high correlation between EGFR mutations and sensitivity to gefitinib therapy in lung cancer patients, particularly in women and non-smokers. The study also revealed significant differences in response rates between Japanese and American patients, suggesting genetic variation plays a crucial role in drug effectiveness.
Researchers found that patients with certain EGFR gene mutations in non-small cell lung cancer (NSCLC) respond well to treatment with Iressa, a kinase blocker. The study identifies the potential for screening patients for these mutations to predict treatment response and benefits ethnic populations differently.
A $3.6M study aims to demonstrate the effectiveness of linking CT lung cancer screening to smoking-cessation programs. Dr. Claudia Henschke's research will use advanced image analysis software to investigate this connection.
A study found that tobacco smoke exposure is responsible for more than half the non-lung cancer death rate in African-American males, and up to two-thirds of their overall cancer death rate. The excess cancer burden can be clearly linked to smoking, with significant declines in mortality rates observed when smoking declined.
Researchers found that combining CT and PET scans significantly enhances radiologists' abilities to precisely define tumor locations for radiation treatments. This improves the efficacy of treatment and limits side effects in non-small-cell lung cancer patients. PET-CT scanning units are now available at hundreds of hospitals nationwide.
Women are more likely to develop lung cancer, with longer survival rates compared to men. Estrogen signaling and hormonal factors may play a role in these differences.

The study also reveals that women's response to targeted therapies is more favorable than men, raising questions about the differences between male and female lung cancer.
Women are more susceptible to lung cancer due to genetic mutations and hormonal changes, resulting in increased adenocarcinoma prevalence. Effective tobacco control measures are crucial to prevent a similar surge in lung cancer rates among women in developing countries.

High folate intake is associated with a lower risk of ovarian cancer, especially among women who consume alcohol.
A new theory by Steven Frank proposes that cancer progression speeds up with age, leading to increased incidence in older adults. As people age, fewer stages remain before cancer develops, resulting in higher cancer rates.
A team of researchers has developed a novel lung cancer treatment using nanoparticle cluster bombs, which have shown promise in treating cancerous lung cells. The new delivery system could potentially be used to target cancer cells while leaving healthy cells alone.
A recent study found that reducing cigarette consumption by 25%, 50%, and 75% did not proportionally decrease the levels of carcinogens in smokers' urine. Despite a reduction in cigarettes smoked per day, NNK metabolites remained relatively stable. The authors suggest that people may compensate for reduced smoking by inhaling longer an...
A Phase II trial of Herceptin combined with chemotherapy found no significant difference in survival times between the treatment and control arms. However, a small subgroup of patients with extremely high levels of HER2 over-expression showed improved response rates and longer disease progression-free periods.
The University Hospitals of Cleveland is using GE's RapidScreen Digital to improve lung cancer detection rates. The CAD system analyzes digital x-ray data and draws circles around suspicious regions, focusing radiologists on potential abnormalities.
A study of annual CT screenings found that 80% of diagnosed Stage I lung cancers were curable. Long-term follow-up showed a high cure rate for patients with screen-diagnosed lung cancer who underwent surgery. The findings support the use of widespread annual low-dose CT screening in high-risk smokers to detect early-stage lung cancer.

The study also revealed that increased smoking and aging significantly increase the risk of developing lung cancer.
A new study reveals that residents of Appalachia experience a disproportionate increase in cancer incidence, particularly lung, colon, rectum, and cervix cancers. The study found that rural residents had even higher rates of these cancers compared to the general population.
A new blood test detects mesothelioma at an early stage, potentially leading to improved patient outcomes. The test uses soluble mesothelin-related proteins (SMR) as a biomarker, which can detect the cancer several years before symptoms appear.

The study suggests that physicians need to address these misconceptions to improve healthcare outcomes in African Americans, who are disproportionately affected by lung cancer.
The SARS epidemic taught four important lessons: the need for global cooperation, improved public health infrastructure, care for patients despite personal risk, and measures to minimize infectious risks to healthcare workers. The response to SARS demonstrates that a strong public health infrastructure can help contain outbreaks and pr...
A new trial found a significant survival benefit from adjuvant chemotherapy in non-small cell lung cancer, increasing patient lifespan by 4.1%. The study suggests that toxicity is still a major concern and calls for better tools to identify patients who will benefit from treatment.
Researchers at Duke University Medical Center have developed a new blood test that can detect lung cancer in its earliest stages using MALDI-TOF MS. The test targets serum amyloid A, a protein elevated in lung cancer patients' blood.
