A new study analyzed data from 3,193 stage III colon cancer patients and found that 78.2% completed adjuvant chemotherapy treatment. Incomplete treatment was linked to physical frailty, treatment complications, and lack of social support.
Women with hereditary non-BRCA breast cancer face a significantly higher risk of developing second primary breast cancers (CBCs), with probabilities ranging from 1.9% to 27.3% over 20 years. Adjuvant hormonal therapy can lower this risk, whereas chemotherapy has no apparent effect.
A large-scale analysis of stage I endometrial cancer patients reveals that adjuvant radiation therapy significantly improves overall and relative survival. Adjuvant RT shows particular benefits for patients with stage IC/grade 1 and grades 3 and 4 disease, resulting in lower death rates.
The use of chemotherapy after surgery for stage III colon cancer has increased, leading to improved 5-year survival rates. Adjuvant chemotherapy benefits younger and elderly patients equally, while black patients with high-grade cancers see less significant improvements.
Chemotherapy has been shown to improve survival rates for patients with advanced colon cancer, regardless of age or sex. The study found that women and the elderly received the same benefit as younger adults, but were less likely to receive chemotherapy treatment.
Researchers found that breast cancer death rates decreased by an estimated 25-38% due to the combination of screening and adjuvant therapy. The study used advanced statistical models to determine the contribution of each method, finding greater uncertainty with screening mammography estimates.
The HERA study found that Herceptin reduces the risk of cancer coming back by 52% and death by 33% in early-stage HER2-positive breast cancer. The results provide new hope for women with this aggressive form of breast cancer, offering improved survival rates.
Researchers have developed a new nasal vaccine that decreases Alzheimer's disease (AD) burden in mice by activating microglia to clear beta-amyloid from the brain. The vaccine combines an FDA-approved multiple sclerosis treatment, glatiramer acetate, with a safe and effective nasal adjuvant that has been tested in humans.
A meta-analysis of nine randomized trials found no significant difference in death rates or disease progression between neoadjuvant and adjuvant systemic therapy. However, neoadjuvant therapy was associated with a higher risk of loco-regional disease recurrence when radiation therapy was used without surgery.
A study presented at the SABCS showed a 30 percent reduction in breast cancer recurrence when postmenopausal women with hormone-receptor-positive breast cancer were switched from tamoxifen to AROMASIN after 2-3 years.

A new study suggests that premenopausal women with ER-negative breast cancer may benefit from adjuvant chemotherapy alone or followed by goserelin, while those with ER-positive tumors show no significant difference in outcomes. The findings support the idea of ovarian suppression as a treatment alternative for some premenopausal women.

The trial involved 674 patients and found that both groups experienced similar rates of disease recurrence and mortality.
A new study found that adjuvant chemotherapy did not improve survival rates for patients with surgically removed non-small-cell lung cancer. Additionally, a study on selenium supplementation revealed that it may increase the risk of squamous cell carcinoma and total nonmelanoma skin cancer in individuals at high risk.
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.
