Background
Neuropathic pain is common among cancer patients and often difficult to treat. This study used Scrambler Therapy, a patient specific electrocutaneous nerve stimulation device, to treat cancer patient with pain.
Methods
Patients received Scrambler Therapy for ten sessions (one daily) over a two- week period. The primary outcome was change in pain numeric rating scale (NRS) at 1 month; secondary outcomes were changes in the Brief Pain Inventory and European Organization for Treatment and Cancer QLC-CIPN-20 over time.
Results
39 patients, mean age 56.5, 16 men and 23 women, were treated over an 18 month period for an average of 9.3 days each. The “now” pain scores reduced from 6.6 before treatment to 4.5 at 14 days, 4.6, 4.8 and 4.6 at 1, 2 and 3 months. (p<0.001) Clinically important and statistically significant improvements were seen in average, least, and worst pain; BPI interference with life scores, and motor and sensory scales on the EORTC CIPN-20. No adverse effects were observed.
Conclusions
In this single arm trial, Scrambler therapy appeared to relieve cancer associated chronic neuropathic pain both acutely and chronically, and provided sustained improvements in many indicators of quality of life.
Objective
We hypothesized that the Oncotype Dx® 21-gene Recurrence Score (RS) could guide neoadjuvant systemic therapy (NST) to facilitate breast conserving surgery (BCS) for hormone receptor positive (HR+) breast cancers.
Methods
This study enrolled patients with HR+, HER2-negative, invasive breast cancers not suitable for BCS (size ≥ 2 cm). Core needle biopsy blocks were tested. For tumors with RS < 11, patients received hormonal therapy (NHT); patients with RS >25 tumors received chemotherapy (NCT); patients with RS 11–25 were randomized to NHT or NCT. Primary endpoint was whether 1/3 or more of randomized patients refused assigned treatment.
Results
Sixty-four patients were enrolled. Of 33 patients with RS 11–25, 5 (15%) refused assignment to NCT. This was significantly lower than the 33% target (binomial test, p=0.0292). Results for clinical outcomes (according to treatment received for 55 subjects) included successful BCS for 75% of tumors with RS < 11 receiving NHT, 72% for RS 11 – 25 receiving NHT, 64% for RS 11 – 25 receiving NCT, and 57% for RS > 25 receiving NCT.
Conclusions
Using the RS to guide NST is feasible. These results suggest that for patients with low or intermediate RS, NHT is a potentially effective strategy.
For adults with T1D using multiple insulin injections and still experiencing suboptimal glycemic control, CGM is cost-effective at the willingness-to-pay threshold of $100,000 per QALY, with improved glucose control and reductions in nonsevere hypoglycemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
