Comparative Study
Racial Differences in the Use and Outcome of Neoadjuvant Chemotherapy for Breast Cancer: Results From the National Cancer Data Base.
To explore racial differences in the use and outcome of neoadjuvant chemotherapy for breast cancer. ⋯ Neoadjuvant chemotherapy is given more frequently to black, Hispanic, and Asian women than to white women. Black women have a lower likelihood of pCR for triple-negative and HER2-positive breast cancer. Whether this is due to biologic differences in chemosensitivity or to treatment or socioeconomic differences that could not be adjusted for is unknown.

Randomized Controlled Trial Multicenter Study
Adjuvant Fluorouracil, Leucovorin, and Oxaliplatin in Stage II to III Colon Cancer: Updated 10-Year Survival and Outcomes According to BRAF Mutation and Mismatch Repair Status of the MOSAIC Study.
The MOSAIC (Multicenter International Study of Oxaliplatin/Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer) study has demonstrated 3-year disease-free survival (DFS) and 6-year overall survival (OS) benefit of adjuvant oxaliplatin in stage II to III resected colon cancer. This update presents 10-year OS and OS and DFS by mismatch repair (MMR) status and BRAF mutation. ⋯ The OS benefit of oxaliplatin-based adjuvant chemotherapy, increasing over time and with the disease severity, was confirmed at 10 years in patients with stage II to III colon cancer. These updated results support the use of FOLFOX in patients with stage III disease, including those with dMMR or BRAF mutation.

For most patients with chronic myeloid leukemia, tyrosine kinase inhibitors (TKIs) have turned a fatal disease into a manageable chronic condition. Imatinib, the first BCR-ABL1 TKI granted regulatory approval, has been surpassed in terms of molecular responses by the second-generation TKIs nilotinib, dasatinib, and bosutinib. Recently, ponatinib was approved as the only TKI with activity against the T315I mutation. ⋯ Whenever possible, we provide practical recommendations, but we concede that cause-directed interventions will require better mechanistic understanding. We suggest that chronic myeloid leukemia heralds a fundamental shift in oncology toward effective but mostly noncurative long-term therapies. Realizing the full potential of these treatments will require a proactive rational approach to minimize long-term cardiovascular and cardiometabolic toxicities.
