Title:

Proton pump inhibitors may reduce the efficacy of ribociclib and palbociclib in metastatic breast cancer patients based on an observational study

Published date:
05/07/2022
Excerpt:
We enrolled hormone receptor-positive, HER2-negative mBC patients treated with endocrine treatment (letrozole or fulvestrant) combined palbociclib or ribociclib alone or with PPI accompanying our observational study....In the palbociclib group, the PFS of the patients using PPIs was shorter than the PFS of the patients not using (13.04 months vs. unreachable, p < 0.001)....In the ribociclib group, the PFS of the patients using PPIs was shorter than the PFS of the patients not using (12.64 months vs. unreachable, p = 0.003)....Our study demonstrated that concomitant usage of PPIs was associated with shorter PFS in mBC treated with both ribociclib and especially palbociclib.

Survival outcomes after neoadjuvant letrozole and palbociclib versus third generation chemotherapy for patients with high-risk oestrogen receptor-positive HER2-negative breast cancer

Published date:
03/22/2022
Excerpt:
Twenty-three of the 53 patients in the letrozole-palbociclib arm received postoperative adjuvant chemotherapy….The 40 months PFS rate was 86.7% [95%CI 78.0–96.4] and 89.9% [95%CI 81.8–98.7] in letrozole-palbociclib and control arms, respectively….NEOPAL suggests that a neoadjuvant letrozole-palbociclib strategy may allow sparing chemotherapy in some patients with luminal breast cancer while allowing good long-term outcomes.

Title:

Palbociclib with letrozole as second-line neo-systemic therapy after failure of neo-adjuvant chemotherapy for luminal type breast cancer: A case report

Published date:
04/09/2021
Excerpt:
A 50-year-old female patient visited our hospital with palpable lump in the right breast....Palbociclib with letrozole was administered as second neo-systemic therapy for 10 months....reduce the size of the tumor and increase the likelihood of avoiding the side effects of surgery. Palbociclib with letrozole may be a good treatment in the preoperative stage for luminal breast cancer that is resistant to chemotherapy.
