Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single center prospective observational cohort study that aims to:

* examine and identify possible risk and susceptibility factors for the incidence and progression of chemotherapy-induced polyneuropathy (CIPN) in female patients primarily operated for early non-metastatic breast cancer who will receive adjuvant chemotherapy containing paclitaxel
* test different neurophysiological methods for early detection of CIPN
* explore changes that underlie the development of CIPN in relation to clinical presentations, neurophysiological assessment, including measures of small nerve fiber dysfunction, and possible biochemical, metabolic and genetic associations
* explore the effects of CIPN in the patient's lifestyle and quality of life for up to 12 months after the initiation of treatment

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The patients who follow the inclusion criteria of the study will be asked to complete:

* a baseline evaluation prior to receiving treatment. This will include a bedside clinical-neurological evaluation, nerve conduction studies (NCS) and quantitative sensory tests of thermal threshold (QST), blood sampling, an oral glucose tolerance test, a skin biopsy, and answering of questionnaires for assessment of symptoms of peripheral neuropathy as well as self-reports on their pre-treatment health and lifestyle status and cancer specific symptomatology
* an on-treatment evaluation 4 weeks after the start of the treatment which will include NCS and QST
* a post-treatment evaluation 4 weeks after the end of treatment which will include the evaluations stated above. During this visit the participants will be provided with the REBECCA lifestyle monitoring system which will include a smartwatch, installation of a mobile app and a PC plugin. The patients will be also asked to fill in some self-rated evaluations as in the pre-treatment period. Researchers, based on the outcomes of the participants, will divide them in two study groups A. CIPN-group and B. No CIPN which will be monitored with the REBECCA monitoring system.
* a final evaluation. This will be performed 8 months after the post-treatment evaluation and it will include clinical-neurological evaluation, nerve conduction studies (NCS) and thermal threshold testing (QST). Additionally, the participants will be requested to fill in the same self-rated evaluations as in the baseline and the post-treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CIPN group

Breast cancer patients that developed strong CIPN symptomatology at post-treatment evaluation (4 weeks after the end of therapy)

Garmin smartwatch

Intervention Type DEVICE

* Physical activity (Activity sessions, type and length of activity, activity intensity estimations)
* Meal detection and meal characteristics (accelerometry and gyroscope data)
* Oxygen saturation (pulse oximetry)
* Number of steps (pedometer)
* Stress level indicators (based on heart-rate analytics)
* Sleep patterns (sleep and wake-up time, sleep quality)

REBECCA Mobile application

Intervention Type OTHER

* GPS positioning (daily location change patterns through pathway analysis and Point-of-interest analysis based on type-of-location automatic detection)
* Self-reports from patients and companions reports on mental and physical health, as well as periodic quality of life evaluations3
* Patient self-uploaded pictures of meals (for evaluation of nutritional habits) and living environment stressors (for evaluation of living environment and self-perceived stressor analysis)

REBECCA PC plug-in

Intervention Type OTHER

* the developed plug-in monitors online activity, collecting anonymized data from web-browsers (Chrome) and social media (Facebook, Youtube and Instagram).
