ne of the most common cancers in women worldwide is breast cancer. A common used therapy in early-stage and metastatic breast cancer involves chemotherapy. Taxanes, microtubule-targeting agents (MTAs), are one of the most used chemotherapeutic agents in breast cancer patients. Unfortunately, this treatment comes with many unfortunate side effects. Chemotherapy-induced peripheral neuropathy (CIPN) is one of these common side effects. This condition involves paresthesia, numbness and/or burning pain in distal limbs. Eventually, loss of temperature sensation, loss of tendon reflexes and pain sensation can occur. Yet, no therapies have been developed to treat CIPN. At the moment, only symptom management is possible. Not only will this condition affect the patients' daily activities, but a chemotherapy dose reduction could also be necessary, influencing the outcome and overall survival rate of the patient. A new and emerging treatment for CIPN is photobiomodulation therapy (PBMT) or low-level laser therapy. During PBMT, visible and/or (near)-infrared laser light is used at the affected area to improve tissue repair and thereby promote functional recovery of peripheral nerves. Studies have shown positive results for patients with diabetic neuropathy. However, no studies have been undertaken specifically for taxane-induced neuropathy (TIN). We hypothesize that PBMT is an effective treatment strategy to prevent sensory symptoms associated with TIN. This can lead to an improved quality of life for the patient and no need for a chemotherapy dose reduction.

Multiwave Locked System® (M6 laser, ASA srl, Arcugnano (VI), Italy) • The PBMT-group will receive twice-weekly laser sessions starting at first until the last week of chemotherapy (9-12 weeks depending on the type of chemotherapy)
• The control group will undergo twice-weekly sham laser sessions starting at first until the last week of chemotherapy (9-12 weeks depending on the type of chemotherapy). The laser device will be placed on the same manner and for the same period of time on the identified body sites, but the device will not be switched on.

The modified total neuropathy score (mTNS)
he mTNS is a composite scale that includes patient report of sensory and motor symptoms, pin sensibility, quantitative vibration thresholds, strength using manual muscle tests, and deep tendon reflexes. The higher the score, the more severe the peripheral neuropathy. The mTNS is a clinically applicable, sensitive screening tool for CIPN.

Functional Assessment of Cancer Therapy/ Gynecologic Oncology Group Taxane scale (FACT/GOG-Taxane)
The Functional Assessment of Cancer Therapy/ Gynecologic Oncology Group Taxane scale (FACT/GOG-Taxane) is a patient questionnaire to test the quality of life of the patients with taxane induced neuropathy (TIN) and can be divided into five components: physical well-being, social/family well-being, emotional well-being, functional well-being, and additional concerns specific for taxane treated patients. The higher the score, the better the quality of life.
