[PMID: 39239446 PMCID: PMC11371994 DOI: 10.1007/s13193-024-01936-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 03/26/2024] [Indexed: 09/07/2024] Open
Abstract
Different targeted therapy options exist for treating HER2-positive metastatic breast cancer patients. This study evaluated the efficacy and tolerability of the lapatinib plus capecitabine combination after TDM-1 in HER2-positive metastatic breast cancer patients. We retrospectively evaluated the HER2-positive metastatic breast cancer patients' data. The patients who progressed after trastuzumab-based chemotherapy and TDM-1 were included in the study. We used the Kaplan-Meier for survival analysis. Eighteen patients were involved in the study. The average age was 48 (range 31-65). De novo metastatic patient's number was 5 (27.8%). The most common metastatic sites were liver (50%), lung (44.4%), and brain (44.4%), respectively. All patients were previously treated with trastuzumab + chemotherapy and TDM-1. Also, seven (38.9%) patients received hormonotherapy and twelve (66.7%) patients received palliative radiotherapy. The complete response ratio was 5.6%, partial response 11.8%, and stable response 29.4%. Median progression-free survival was found as 5.5 (95% CI, 3.2-7.7) months. The hematological and non-hematological toxicity ratio was 41.2% and 52.9%, respectively. Grade 3-4 toxicity (diarrhea, anemia, and mucositis) was observed in four (22.2%) patients. The median OS duration was 8.2 months (95% CI, 4.3-12.0). Treatment options are limited in heavily pretreated HER2-positive breast cancer patients. Despite a small number of patients, this study showed that the lapatinib plus capecitabine combination was effective and well-tolerated in heavily pretreated HER2-positive breast cancer patients after TDM-1.

Implementation of CDK4/6 Inhibitors and its Influence on the Treatment Landscape of Advanced Breast Cancer Patients - Data from the Real-World Registry PRAEGNANT. Geburtshilfe Frauenheilkd 2022; 82:1055-1067. [PMID: 36186151 PMCID: PMC9525148 DOI: 10.1055/a-1880-0087] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 06/15/2022] [Indexed: 10/31/2022] Open
Abstract
Background Comprehensive data from prospective clinical trials have led to a high level of evidence establishing CDK4/6 inhibitors in combination with endocrine treatment (CDK4/6i + ET) as a standard for the treatment of HER2-negative, hormone receptor-positive (HER2- HR+) breast cancer patients in the first-line advanced therapy setting. Data on patient populations that have been treated in the real-world setting may provide an insight into changes of patient characteristics and prognosis over time. Methods The data were extracted from the prospective real-world registry PRAEGNANT (NCT02338167). Patients had to have HER2- HR+ advanced breast cancer in the first-line metastatic setting. The chosen therapies were described as well as progression-free survival (PFS) and overall survival (OS) in relation to the given therapies and time periods during which they were indicated. Results CDK4/6 inhibitors have been rapidly implemented since their introduction in November 2016. In recent years (2018 - 2022), about 70 - 80% of the patient population have been treated with CDK4/6 inhibitors, while endocrine monotherapy was given to about 10% and chemotherapy to about 15% of all patients. The prognosis was worst in patients treated with chemotherapy. Recently, mainly patients with a good prognosis are being treated with endocrine monotherapy, and patients who are treated with chemotherapy have an unfavorable prognosis. The PFS and OS of patients treated with CDK4/6i + ET have remained similar over time despite changes in patient characteristics. Conclusion A treatment with CDK4/6i + ET has rapidly become the therapy standard for patients in the first-line advanced breast cancer setting. After the implementation of CDK4/6i + ET, endocrine monotherapy is only given to patients with a very favorable prognosis, while chemotherapy is provided to patients with a rather unfavorable prognosis. These changes in patient characteristics did not seem to influence the prognosis of patients treated with CDK4/6i + ET.
