The future of drug delivery involves 'smart' systems addressing issues like gut, skin, and lung penetration, promising improved patient compliance and treatment efficacy.
A widely used anti-nausea drug, dexamethasone, may interfere with cancer chemotherapy. Pretreatment with dexamethasone reduces the ability of paclitaxel and doxorubicin to kill cancer cells by upregulating genes that protect breast cancer cells from cell death.
Women experience a range of physical symptoms, including hot flashes and vaginal dryness, following breast cancer treatment. Mood and emotional functioning are similar among all women at the end of primary treatment.

Participants reported a decrease in nausea and vomiting, as well as improved mental state, after using the technology.
A meta-analysis of genetic counseling for breast, ovarian, and colorectal cancer found improved knowledge of cancer genetics, but no impact on perceived risk. A gene mutation affecting folate metabolism alters the sensitivity of colon and breast cancer cells to chemotherapy drugs.
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.
A nationwide survey found that 56% of women with early stage breast cancer received less than 85% of their prescribed chemotherapy dose intensity. Treatment delays and dose reductions were common due to neutropenia, a shortage of infection-fighting white blood cells.
St. Jude scientists have discovered a new method to target the Topoisomerase 1 enzyme, crucial for cell division, leading to potential novel anti-cancer drugs that can work in combination with existing agents. This approach may also reduce cancer cells' ability to become resistant to treatment.

The two-year disease-free survival rate is 85 percent, offering a promisi...
A phase II trial found that AMD-3100, a new drug, increases the availability of stem cells in cancer patients undergoing transplantation. This boosts the chances of successful transplantation and may reduce the number of collections needed.
A recent study found that over 20% of patients with estrogen-negative breast cancer had a complete pathologic response to treatment, compared to just 5% in estrogen-positive cancers. The researchers suggest that endocrine therapies may be a more effective initial treatment for these patients.
A study of 362 patients has shown that breast conservation after neoadjuvant chemotherapy is a safe and effective alternative to mastectomy for many patients. The key to success lies in careful patient selection and coordination among treatment specialists, with low rates of local-regional recurrence reported.
A new study found that chemotherapy and radiation together is more effective than sequential treatment in preserving the voice box, with 88% of patients still having their voice after two years. Overall survival rates were similar for all three treatment options.
