Despite increased incidence and changing demographics, recent diagnosis years are not associated with decreased mortality. The study highlights an ongoing need to improve treatments for this challenging population.
A new study published in the Journal of the National Cancer Institute found that epoetin alfa can help alleviate anemia in high-risk breast cancer patients while maintaining overall and relapse-free survival rates. However, the treatment may increase the risk of thrombotic events.
The study found that the median time to activation of phase 1-2 trials decreased from 541 to 442 days, and for phase 3 trials from 727 to 395 days. The reforms led to faster initiation of NCI-sponsored trials, ultimately benefiting patients in need of new treatments for cancer.
A cohort study published in JNCI found a statistically significant elevated standardized incidence ratio for primary liver cancer among workers exposed to trichloroethylene. However, no significant risk was observed for kidney cancer or non-Hodgkin lymphoma. The authors suggest that further research is needed to confirm these findings.

A recent study found that tumor boards have a modest association with the types of treatments patients receive for certain cancers. For example, lung cancer and prostate cancer patients were more likely to receive higher-quality care when treated at hospitals with tumor boards. However, other types of cancer care remained unaffected by...
A study published in the Journal of the National Cancer Institute found no significant difference in toxicity between proton radiotherapy (PRT) and intensity-modulated radiotherapy (IMRT) among Medicare beneficiaries with prostate cancer at 12 months post-treatment. Despite its widespread use, PRT's benefits and harms remain unknown.

The study suggests that metabolism plays a role in the pathophysiology of pancreatic cancer, potentially leading to improved survival rates with early detection and therapeutic interventions.
A pooled analysis of eight cohort studies found that women with higher circulating carotenoid levels had statistically significantly lower breast cancer risk. The inverse association was strongest for estrogen receptor-negative (ER-) breast cancers, highlighting carotenoids as a potential modifiable risk factor.
Researchers found a significant association between NSAID use and reduced risk of hepatocellular carcinoma (HCC) and death from chronic liver disease. Aspirin use was found to have the strongest protective effect, with participants experiencing a 41% reduced risk of HCC and 45% reduced risk of CLD mortality.
A cost-effectiveness analysis found that KRAS testing is cost-saving, while BRAF testing offers additional savings. The study suggests that molecular testing primarily generates cost savings by identifying nonresponders, rather than improving survival.
A study found that DCIS patients with combined RB and PTEN loss are at high risk of progressing to invasive breast cancer. Women lacking both genes are over 5 times more likely to develop invasive breast cancer.

A study found that stage IV cancer patients on Medicare are more likely to undergo high-cost diagnostic imaging procedures, which may be driven by the increasing number of treatment options available. The use of imaging has steadily increased between 1995 and 2006, with costs rising faster than overall cancer care costs.
A study published in the Journal of the National Cancer Institute found that breast cancer mortality rates in Swedish women aged 40-69 declined at a rate similar to the prescreening period, suggesting limited impact of mammography screening. Researchers note potential limitations, including obesity and population mobility biases.

The research suggests that exercise may provide benefits such as improved insulin levels, reduced inflammation, and enhanced immunity for cancer survivors.
A study published in JNCI found a strong association between genetic variants rs1051730-rs16969968 and objective measures of tobacco exposure, indicating that lung cancer risk is largely mediated by level of tobacco exposure. The research used data from six independent studies to analyze self-reported cigarette consumption and plasma o...
The Journal of the National Cancer Institute warns that dietary supplements may lower cancer risk, but only observational studies support this claim. Randomized controlled trials show no correlation between supplement use and reduced cancer risk.
A DNA repair pathway-focused score has been developed to predict chemotherapy response in ovarian cancer patients. The score is positively correlated with complete response rate, recurrence-free survival, and progression-free survival, and outperforms other clinical factors in predicting overall survival.
A study found that over 10 years, 30.8% of women had diagnostic mammograms, while 61.5% underwent ipsilateral invasive procedures following BCS. The high rates may be due to concerns about recurrence, and the authors highlight the need for better prognostic biomarkers to minimize overtreatment.
A study found that women with false-positive mammography results have a statistically significant higher risk of developing breast cancer compared to those who test negative. The long-term excess risk underscores the need for regular screenings despite potential anxiety from false-positive experiences.
A study found that wide negative margins are associated with a lower risk of local recurrence in women with ductal carcinoma in situ treated with breast-conserving surgery. Researchers recommend considering radiotherapy as the top priority to complement targeting wider free margins.
