Prevention, Monitoring, and Management of Cardiac Dysfunction in Patients with Metastatic Breast Cancer

3 months 1 week ago
AbstractCardiac monitoring is becoming an important part of breast cancer care. Breast cancer and cardiovascular disease (CVD) share many common risk factors, and it is estimated that by the median age of diagnosis, many patients with breast cancer will have established or subclinical CVD. In addition, a number of treatments for metastatic breast cancer are known to have cardiac effects. As such, there is a clear need to prevent, identify, and effectively manage cardiovascular events in patients with breast cancer. Current clinical practice for patients with metastatic breast cancer involves a comprehensive set of assessments to ensure efficacy and safety of treatment. Adding cardiac monitoring to the assessments already required for patients with breast cancer may improve survival and quality of life. Currently, cardiac monitoring is recommended for several breast cancer treatments, and guidelines related to cardiac monitoring are available. Here, we review the risk of CVD in patients with breast cancer, providing an overview of the cardiac events associated with standard therapies for metastatic breast cancer. We also assess the current clinical recommendations relating to cardiac monitoring, and practical management strategies for oncologists. Cardio‐oncology is a growing medical subspecialty that promotes the need for effective cancer therapy while minimizing cardiac effects. Integrating cardiac monitoring into routine clinical practice may safeguard patients with metastatic breast cancer against adverse cardiac effects.Implications for Practice.This review details the common risk factors associated with cardiovascular disease that are frequently observed in patients with metastatic breast cancer, as well as the adverse cardiac effects of many therapies that are commonly prescribed. The review also provides a rationale for routine and comprehensive cardiovascular assessment of all patients at baseline, and during and after therapy depending on the treatment and presence of risk factors for cardiovascular disease. The medical discipline of cardio‐oncology is increasingly being recognized as an important part of clinical practice to ensure effective cancer therapy while maintaining cardiac health.

Effectiveness of EGFR‐TKIs in a Patient with Lung Adenocarcinoma Harboring an EGFR‐RAD51 Fusion

3 months 1 week ago
AbstractEpidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (EGFR‐TKIs) have become the first choice for patients with sensitive mutations and have significantly improved prognosis. EGFR exon 19 deletions and L858R mutation in exon 21 are the most common sensitive mutations in lung adenocarcinoma. With advances in detection technology, some rare variants of EGFR have been detected, including EGFR kinase domain duplications and EGFR fusions. Only a few reports have revealed the effectiveness of EGFR‐TKIs in patients with these rare variants. In this study, we report a case of EGFR‐RAD51 fusion in lung adenocarcinoma that showed a response to icotinib; these findings provide additional support for the use of EGFR‐TKIs for patients with these atypical variants.Key Points. A young patient with lung adenocarcinoma harboring a rare EGFR‐RAD51 fusion who responded to icotinib with a PFS of longer than 15 months.All reported EGFR‐RAD51 fusions have the same breakpoints and show responses to EGFR‐TKIs including icotinib, except for one patient who responded to chemotherapy.Although EGFR fusion is a rare EGFR variant type, the efficacy of EGFR‐TKIs suggests the necessity for new detection technology, such as NGS, for patients with lung adenocarcinoma.The clinical usage of NGS could maximize the benefits of precision medicine in patients with cancer.The current case provides new evidence for the efficacy of icotinib in patients with the rare EGFR‐RAD51 fusion and EGFR‐activating mutations.

A Phase I/II Open‐Label Study of Nivolumab in Previously Treated Advanced or Recurrent Nasopharyngeal Carcinoma and Other Solid Tumors

3 months 2 weeks ago
AbstractLessons Learned. Nivolumab treatment at doses of 3 mg/kg once every 2 weeks (Q2W), 240 mg Q2W, and 360 mg once every 3 weeks was well tolerated in the Chinese population, with no new safety signals identified.Comparison of intensive pharmacokinetic profiles of nivolumab at 3 mg/kg Q2W in Chinese versus global populations revealed no ethnic differences of nivolumab treatment.Nivolumab shows promising preliminary antitumor activity in nasopharyngeal carcinoma.Background.This phase I/II study investigated the safety and pharmacokinetics (PK) of nivolumab (anti‐programmed cell death‐1 monoclonal antibody) in Chinese patients with nasopharyngeal carcinoma (NPC) and other solid tumors.Methods.A dose evaluation phase (3 mg/kg once every 2 weeks [Q2W]) was followed by a cohort expansion phase (3 mg/kg Q2W or flat doses of 240 mg Q2W or 360 mg once every 3 weeks).Results.In the dose evaluation phase, 8/8 patients completed one cycle with no dose‐limiting toxicities. At data cutoff, 46/51 patients were evaluable for safety (all cohorts). Treatment‐related adverse events (TRAEs) occurred in 35 (76%) patients and were primarily grade 1–2; one patient (3 mg/kg Q2W) discontinued because of study drug toxicity. Intensive PK profiles at 3 mg/kg, 240 mg, and 360 mg were well characterized at single and multiple doses of nivolumab. An objective response was determined in six (6/46) patients, four (4/32) of whom had NPC tumors.Conclusion.Nivolumab monotherapy at 3 mg/kg and flat doses of 240 mg and 360 mg were well tolerated in this Chinese patient population, with PK profiles at 3 mg/kg being similar to those of global patients. Preliminary efficacy results showed promising antitumor activity of nivolumab in advanced NPC.
