ABSTRACT

Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved as maintenance therapy of recurrent ovarian cancer (OC) patients with a BRCA mutation. To achieve the maximum clinical benefit, adherence to olaparib must be persistent. However, in clinical practice, this is challenged by the frequent suboptimal management of toxicities. In view of the expanding use of olaparib also in Italy, physicians must learn how to adequately and promptly manage drug toxicities not to unnecessarily interrupt or reduce the dose. The experts agreed that nausea,vomiting, anemia, and fatigue are the most frequent events experienced by OC patients on olaparib, and that these toxicities usually develop early during treatment, are mainly of grade 1-2 and transient and can be managed with simple non-pharmacological interventions. By sharing their real-world experiences, the panel prepared, for each toxicity, an algorithm organized by grade and besides the procedures indicated in the local label, included supportive care interventions based also on nutritional and lifestyle modifications and psycho-oncology consultation. Moreover, in view of the tablet entry into the Italian market, the full and reduced dosages of capsules and tablets were compared. This practical guidance is intended to be a tool to support especially less-experienced physicians in the management of these complex patients, with the aim to help preventing the worsening of patients' conditions and the unnecessary interruption/reduction of olaparib dosage, which may jeopardize treatment efficacy.

ABSTRACT

BACKGROUND: We reported the results of an Italian large retrospective analysis that evaluated the effectiveness and safety of T-DM1 in 'field-practice' breast cancer patients. We performed a sub-analysis to investigate the clinical activity of T-DM1 in patients with brain metastases (BMs). METHODS: The records of 87 adult women with HER2-positive breast cancer and BMs treated with T-DM1 were reviewed. Their clinical outcomes were compared with those of 216 patients without central nervous system (CNS) involvement. RESULTS: Response to T-DM1 treatment in BMs was available for 53 patients in the BM group (60.9%): two patients reported a complete response (3.8%), 11 patients obtained partial response (20.7%; overall response rate: 24.5%), 16 patients had a stable disease (30.1%). Regarding extracranial disease, a total of 77 and 191 patients were evaluable for response in BM group and non-BM group, respectively. The overall response rate was 35.1% in the BM group and 38.3% in the non-BM group; disease control rate was 53.3% and 66.6%, respectively. At a median follow-up of 16 months (range: 1-55), median cumulative progression-free survival (PFS) was 7 months (95% CI: 5.4-8.6) in the BM group and 8 months (95% CI: 5.7-10.3) in the non-BM group. In the second-line setting, PFS was 5 (95% CI: 3.1-6.9) versus 11 (95% CI: 7.1-14.9) months (p = 0.01). Overall survival was 14 months (95% CI: 12.2-15.8) in the BM group and 32 months (95% CI: 24.4-39.6) in the non-BM group (p < 0.0001). CONCLUSIONS: T-DM1 is active in breast cancer patients with BMs.
