Brief summary
Researchers plan to study the natural history of ado-trastuzumab emtansine (T-DM1)-induced neuropathy both in patients without any history of neuropathy or previous neurotoxic agent use and in patients who have such a history.

Inclusion criteria
* Planning to receive three or more doses T-DM1 for HER2-positive metastatic breast cancer (any line) or for earlier-stage breast cancer. The patient may have received one dose of T-DM1, prior to study entry if it has not been longer than 14 days since that dose and that the patient will be able to complete the required baseline questionnaire within 14 days of their first dose of T-DM1. * Patients with previous use of neurotoxic antineoplastic agents (excluding previous use of T-DM1), pre-existing CIPN, or peripheral neuropathy secondary to other causes will be able to be enrolled in the study. * The patient plans to continue clinical follow-up at the same institution, where the patient entered the study. * Provide informed consent. * Ability to complete questionnaire(s) in English by themselves or with assistance.
Exclusion criteria
* Previous use of T-DM1 * Concomitant use of other neurotoxic anticancer agents including cisplatin, carboplatin, oxaliplatin, docetaxel, paclitaxel, vincristine, eribulin, vinorelbine, thalidomide, lenalidomide, bortezomib, or epothilones. If the patient used any of these previously, then they must have been stopped for at least 7 days prior to study entry. * Current use of commonly used drugs for the treatment of peripheral neuropathy, including duloxetine, gabapentinoids (pregabalin and gabapentin), venlafaxine, nortriptyline, or amitriptyline (including use of these medications for things other than neuropathy). If the patient used any of these previously, then they must have been stopped for at least 7 days prior to study entry.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in chronic neuropathy symptoms | Baseline, approximately 22 months | Measured using the European Organisation of Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-induced peripheral neuropathy (CIPN) twenty-item scale (EORTC QLQCIPN20), a validated instrument designed to elicit cancer patients' experience of symptoms and functional limitations related to chemotherapy-induced peripheral neuropathy. The total score of CIPN20, each of the three subscale scores (sensory, motor, autonomic), and each individual item of the CIPN20 tool will be computed following standard scoring algorithm and converted into a 0-100 scale; higher scores indicate greater severity of neuropathy symptoms. |
