Usually, paclitaxel administration is preceded by premedication, which consists of a set of medications intended to prevent allergic reactions during chemotherapy. This practice is very common, even though scientific studies show that it is safe to discontinue premedication if no allergic reaction occurs after the first two doses of paclitaxel. Moreover, when given during all 12 doses of weekly chemotherapy, premedication could negatively affect quality of life (for example, insomnia followed by significant fatigue may occur several days after taking dexamethasone). However, no study has yet evaluated whether stopping premedication after two well-tolerated doses could improve the quality of life of patients receiving paclitaxel.
Our research project therefore aims to concretely evaluate the impact of discontinuing this premedication on the quality of life of patients with non-metastatic breast cancer. More specifically, we want to compare the quality of life between two groups of patients. The first group will include patients whose premedication is discontinued starting from the third dose of paclitaxel if they did not experience a reaction during the first two doses. The second group will include patients who continue to receive the premedication given during the first cycles, as is usual practice.
The study will also monitor the occurrence of adverse events or side effects (whether related to premedication or paclitaxel itself), as well as changes in chemotherapy dosing if applicable. It is sometimes necessary to reduce chemotherapy doses due to adverse effects, even when they originate from premedication, since it can be difficult to determine the contribution of each medication.

The quality of life will be assessed using the validated EORTC-QLQ-C30 version 3.0 questionnaire which is designed to measure the quality of life (physical, psychological, and social functioning) in cancer patients. | From enrollment (week 3) to week 9 of treatment |

| Compare the incidence and severity of adverse events between the two groups using a modified ESAS-r questionnaire. | Compare the incidence of adverse events between the two groups (both from paclitaxel and from premedication in the premedication group). We will use the modified ESAS-r questionnaire. The ESAS-r (Edmonton Symptom Assessment System-Revised) is a validated, 10-item tool used to assess the severity of common symptoms in patients with cancer or those receiving palliative care. The original ESAS-r questionnaire measures 9 core symptoms-plus one blank space for a patient-specific symptom. We will add 16 questions about symptoms that may be influenced by the addition or withdrawal of premedication. | From enrollment (week 3) to the end of treatment (week 12) |
