The impact of adjuvant chemotherapy on breast cancer prognosis has been demonstrated in randomized trials, but its impact is unknown in real-world populations. The aim of this study was to evaluate the effect of adjuvant chemotherapy on the survival of breast cancer patients in an unselected population. This prospective cohort study included 32, women treated at the Institut Curie between and for a first invasive breast cancer without metastasis.
How relevant the Nala data are in the real world is a separate question, however. Still, US approval is not out of the question. Nala had been run under a special protocol assessment, implying that the FDA supported its analysis plan, under which a win on either the PFS or the OS co-primary endpoint would have deemed the result positive.
Secondary efficacy endpoints of disease-free survival and distant recurrence—free interval also demonstrated clinically meaningful improvements with T-DMI. Patients with HER2-positive early breast cancer who have residual invasive disease after neoadjuvant chemotherapy and HER2-targeted therapy have a high risk of recurrence and death. The current standard of care for these patients is continuation of the same HER2-targeted therapy in the adjuvant setting for 1 year.
Patients with triple-negative breast cancer who delayed starting adjuvant chemotherapy for more than 30 days after surgery were at significantly higher risk for disease recurrence and death compared with those who started the treatment in the first 30 days after surgery, according to a retrospective study presented at the San Antonio Breast Cancer Symposiumheld Dec. Others recommend starting as soon as clinically possible within 31 days of surgery, however, the optimal time to initiate chemotherapy is unknown. Morante and colleagues found that patients who delayed starting adjuvant chemotherapy for more than 30 days after surgery had a more than 90 percent increased risk for disease recurrence and death compared with those who started the treatment in the first 30 days after surgery. Morante and colleagues retrospectively analysed data obtained from the medical records of patients with stage 1—3 triple-negative breast cancer who had undergone surgery and went on to receive adjuvant chemotherapy in a public institution.

This study presents comprehensive real-world data on the use of anti-human epidermal growth factor receptor 2 HER2 therapies in patients with HER2-positive metastatic breast cancer MBC. All therapy lines are documented. This analysis describes the utilization of anti-HER2 therapies as well as therapy sequences.
Neoadjuvant chemotherapy refers to medicines that are administered before surgery for the treatment of breast cancer. Your doctors may recommend neoadjuvant chemotherapy due to the size of the tumor, since the drugs may shrink the tumor and give you more surgical options. In some cases, a woman who would have needed a mastectomy due to the large size of her tumor can become a candidate for lumpectomy by shrinking the invasive tumor prior to surgery.

The goal in treating eBC is to provide people with the best chance for a cure, which may involve treatment before and after surgery as part of a comprehensive treatment approach. Kadcyla is the first Roche medicine approved under the RTOR pilot programme, which is exploring a more efficient review process to ensure safe and effective treatments are available to patients as early as possible. The primary endpoint of the study is iDFS, which in this study is defined as the time from randomisation free from invasive breast cancer recurrence or death from any cause. Secondary endpoints include iDFS including second primary non-breast cancer, disease-free survival and overall survival.
