Safety and oncological effectiveness after desensitization in patients with previous hypersensitivity reactions to chemotherapy.

HSRs to paclitaxel manifest in the first 1-2 cycles and to carboplatin after 6 cycles. Symptoms include cardiovascular, atypical neuromuscular and urticaria. Changing treatment lines impacts prognosis. Our study revealed that ovarian cancer patients undergoing desensitization protocols achieved longer progression-free intervals. All patients successfully reached total dose desensitization. This study provides evidence of the effectiveness and safety of desensitization and promising perspective for continuing first-line treatment with HSRs.
