Eribulin long-term response and rechallenge: report of two clinical cases.

The antimitotic agent eribulin, a synthetic analog of halichondrin B isolated from a marine sponge, resulted particularly effective in improving the overall survival of heavily pretreated metastatic breast cancer (MBC) patients in randomized Phase III clinical trials and real-life studies. However, only scant information is available on the clinical experiences of patients who underwent long-lasting eribulin treatment followed by a rechallenge. Here we presented two cases of MBC women previously treated with several lines of chemotherapy and hormonal therapies, who underwent long-lasting treatment and rechallenge with eribulin, showing a partial response in both periods.

Gemcitabine plus mitoxantrone and prednisone in the palliative treatment of hormone-resistant prostate cancer (HRPC): A phase II study (GOAM 01.01 study).

Background: The present exploratory phase II study was performed to evaluate the activity and tolerability of adding a second agent (gemcitabine) to the well-tolerated mitoxantrone/prednisone regimen in patients with locally advanced or metastatic prostate cancer no longer responsive to hormonal treatment.

Patients And Methods: Forty-three patients with hormone-refractory prostate cancer (HRPC) were included in the study from May 2000 to April 2004. Their median age was 71 years (range, 56-81) and their median Karnofsky performance status (KPS) was 90 (range, 70-100).
