    Metastatic small cell carcinoma of the prostate in an octogenarian with significant response to first-line chemotherapy
    (OAT, 2017-03) Wood, Anthony; Adra, Nabil; Cheng, Liang; Pili, Roberto; Department of Pathology and Laboratory Medicine, IU School of Medicine
    Patients with small cell carcinoma of the prostate generally present with metastatic disease and have an estimated life expectancy measured in months. In this brief report, we present a case of rapidly progressive metastatic small cell carcinoma of the prostate in an octogenarian with significant response to split-dosed cisplatin and etoposide. This case report shows that cautious treatment with platinum-based regimens should still be considered in elderly patients given the potential for improvement in performance status and quality of life with chemotherapy. Additionally, this case highlights that platinum-based regimens are still considered the therapeutic backbone of prostate cancers with a mixed small cell carcinoma and adenocarcinoma phenotype.

    Phase I study of the mTOR inhibitor everolimus in combination with the histone deacetylase inhibitor panobinostat in patients with advanced clear cell renal cell carcinoma
    (SpringerLink, 2020-08) Wood, Anthony; George, Saby; Adra, Nabil; Chintala, Sreenivasulu; Damayanti, Nur; Pili, Roberto; Medicine, School of Medicine
    Background: Preclinical studies suggested synergistic anti-tumor activity when pairing mTOR inhibitors with histone deacetylase (HDAC) inhibitors. We completed a phase I, dose-finding trial for the mTOR inhibitor everolimus combined with the HDAC inhibitor panobinostat in advanced clear cell renal cell carcinoma (ccRCC) patients. We additionally investigated expression of microRNA 605 (miR-605) in serum samples obtained from trial participants. Patients and Methods: Twenty-one patients completed our single institution, non-randomized, open-label, dose-escalation phase 1 trial. miR-605 levels were measured at cycle 1/day 1 (C1D1) and C2D1. Delta Ct method was utilized to evaluate miR-605 expression using U6B as an endogenous control. Results: There were 3 dosing-limiting toxicities (DLTs): grade 4 thrombocytopenia (n = 1), grade 3 thrombocytopenia (n = 1), and grade 3 neutropenia (n = 1). Everolimus 5 mg PO daily and panobinostat 10 mg PO 3 times weekly (weeks 1 and 2) given in 21-day cycles was the recommended phase II dosing based on their maximum tolerated dose. The 6-month progression-free survival was 31% with a median of 4.1 months (95% confidence internal; 2.0-7.1). There was higher baseline expression of miR-605 in patients with progressive disease (PD) vs those with stable disease (SD) (p = 0.0112). PD patients' miR-605 levels decreased after the 1st cycle (p = 0.0245), whereas SD patients' miR-605 levels increased (p = 0.0179). Conclusion: A safe and tolerable dosing regimen was established for combination everolimus/panobinostat therapy with myelosuppression as the major DLT. This therapeutic pairing did not appear to improve clinical outcomes in our group of patients with advanced ccRCC. There was differential expression of miR-605 that correlated with treatment response.
