Comparative Study Observational StudyCancer risk management among female BRCA1/2, PALB2, CHEK2, and ATM carriers.
Identification of inherited breast cancer may guide cancer risk management. We sought to compare risk management practices across women with inherited breast cancer genes. ⋯ These findings suggest high rates of both contralateral mastectomies among those with unilateral breast cancer and BM among those without a breast cancer diagnosis across women with P/LP variants in high and moderate penetrance breast cancer genes. BO was also often utilized for risk reduction across these women. These findings suggest potential overtreatment through risk-reducing surgery, and highlight the importance of promoting guideline-adherent, risk-appropriate care.

Sensory profiles in women with neuropathic pain after breast cancer surgery.
We performed a detailed analysis of sensory function in patients with chronic post-surgical neuropathic pain (NP) after breast cancer treatments by quantitative sensory testing (QST) with DFNS (German Research Network on Neuropathic Pain) protocol and bed side examination (BE). The nature of sensory changes in peripheral NP may reflect distinct pathophysiological backgrounds that can guide the treatment choices. NP with sensory gain (i.e., hyperesthesia, hyperalgesia, allodynia) has been shown to respond to Na+-channel blockers (e.g., oxcarbazepine). ⋯ Extensive sensory loss is characteristic for chronic post-surgical NP several years after treatment for breast cancer. These patients are unlikely to respond to Na+-channel blockers.
