Background: Neoadjuvant pembrolizumab plus chemotherapy and adjuvant pembrolizumab have been established as the optimal systemic therapies for patients with early stage triple-negative breast cancer (TNBC); however, their efficacy and feasibility in the Japanese population remain unexplored.
Methods: This study included patients with early stage TNBC or low estrogen receptor (ER) positivity (1-9%) with human epidermal growth factor receptor type 2- (HER2-) negative breast cancer who received neoadjuvant pembrolizumab plus chemotherapy from October 2022 at Cancer Institute Hospital of Japanese Foundation for Cancer Research. Information regarding clinicopathological features, systemic therapy, treatment outcomes, and adverse events of patients who underwent surgery by February 2024 was retrospectively collected.
Article Synopsis
- Perioperative FEC therapy is a common treatment for breast cancer, but over 20% of patients experience febrile neutropenia (FN), which pegfilgrastim is often used to prevent.
- A study on pegfilgrastim's long-term safety found no significant differences in blood cell counts or long-term effects after one year of use.
- Pegfilgrastim administration significantly reduced the incidence of FN (6.5% with pegfilgrastim vs. 22.8% without), indicating it can be safely used for one year in breast cancer patients undergoing chemotherapy.
Background: Absolute lymphocyte count (ALC) is a predictive and prognostic factor for various tumor types, including breast cancer. Palbociclib is a CDK4/6 inhibitor widely used for the treatment of metastatic estrogen receptor (ER)-positive, HER2-negative breast cancer. However, predictive biomarkers of the efficacy of palbociclib remain unelucidated.

- A study investigated the costs and survival outcomes associated with pegfilgrastim prophylaxis for febrile neutropenia (FN) in breast cancer patients undergoing chemotherapy in Japan.
- The pegfilgrastim group had higher median total medical costs compared to the non-pegfilgrastim group but did not show a significant difference in FN hospitalization costs.
- Despite increased costs, there was no significant difference in 3-year overall survival rates between the two groups, suggesting pegfilgrastim should be used selectively based on individual FN risk factors rather than routinely.
Background: Adolescents and young adults (AYAs) represent a small proportion of patients with cancer. The genomic profiles of AYA patients with cancer are not well-studied, and outcomes of genome-matched therapies remain largely unknown.
Patients And Methods: We investigated differences between Japanese AYA and older adult (OA) patients in genomic alterations, therapeutic evidence levels, and genome-matched therapy usage by cancer type.
