May 15, 2018

Here, we discuss how to improve adherence to endocrine therapy in women with HR-positive breast cancer, as well as the side effects and the reasons for discontinuation.

Ready, Fire, Aim: Addressing Issues Associated With Multigene Panel Testing for Cancer Susceptibility

September 15, 2016

Panel testing has important advantages but is being misused due to payer constraints and laboratory marketing pressures. Much testing is haphazard and results in utilization of limited genetic counseling resources in the discussion of variants of uncertain significance and low-penetrance gene mutations.

Bisphosphonates in the Prevention and Treatment of Bone Metastases

September 01, 2003

Bisphosphonates have an established role in treating tumor-inducedhypercalcemia and decreasing the incidence of skeletal-related events.Recent data suggest that these agents may also prevent skeletal metastases.This review explains how cancer metastasizes to bone and howbisphosphonates may block this process, with a summary of clinicaltrials supporting the use of bisphosphonates to treat and prevent bonemetastases. For skeletal metastases in patients with breast cancer,multiple myeloma, or other solid tumors, bisphosphonates are importantadjuncts to systemic therapy. Despite promising results in metastaticprostate cancer, additional trials are needed before bisphosphonatesbecome part of standard treatment in this setting. Ongoing trials areevaluating the preventive role of the third-generation bisphosphonatesin breast cancer patients. Until the results of these trials are presented,bisphosphonates should only become a component of adjuvant treatmentin the context of a clinical trial. Bone loss, a common consequenceof cancer treatment, should be treated with the usual measures indicatedfor the management of osteoporosis, including bisphosphonates.

Potential Role of Selective COX-2 Inhibitors in Cancer Management

May 01, 2002

Tumorigenesis is a complex process, and understanding the mechanisms behind tumorigenesis is key to identifying effective targeted therapies. Prostaglandins are signaling lipophilic molecules derived from phospholipids that are involved in normal physiologic functions.
