The combination of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) with endocrine therapy (ET) is the standard-of-care for estrogen receptor (ER)-positive, HER2-negative (ER+/HER2- advanced/metastatic breast cancer (mBC). However, the impact of CDK4/6i on circulating immune cells and circulating tumor cells (CTCs) in patients receiving CDK4/6i and ET (CDK4/6i+ET) remains poorly understood. This was a prospective cohort study including 44 patients with ER+/HER2- mBC treated with CDK4/6i+ET in either first or second line.

Article Synopsis
  • - Colorectal cancer (CRC) exhibits significant genetic diversity influenced by various genomic instability pathways, resulting in differences within tumors and their surrounding environments.
  • - A study of 136 CRC samples revealed that this diversity arises from molecular alterations that occur at different rates, with certain genomic features being better predictors of heterogeneity in tumor subtypes and locations.
  • - The research indicates that higher levels of genetic and microenvironment diversity are linked to a reduced likelihood of metastasis, while certain genetic changes that appear later may promote the spread of cancer cells.

A 76-year-old woman presented to the medical oncology outpatient clinic with painful, burning, pruritic erythematous plaques involving both palms and axillae that had suddenly appeared five days before. Examination revealed no additional relevant findings and laboratory studies did not show any alteration. The patient had been recently diagnosed with a high-grade angiosarcoma of the breast (probably radiation induced) and after frequent local recurrences, was being treated with liposomal doxorubicin (three cycles were administered, the last of which was seven days before the appearance of the mentioned lesions).

Mucosal melanoma accounts for 1% of all melanomas. It is more aggressive than cutaneous melanoma, and local excision provides the best disease-free survival. The vast majority of patients eventually develop metastases, with a metastatic pattern independent of the primary tumor site.
