Project description:Incidence of canine mammary carcinoma is two times higher than the rate of human breast cancer. Mammary tumors are the most common type of cancer in intact female dogs and account for about half of all neoplasms in these dogs. Well-established models of breast cancer have shown that neoplastic cells often have a loss of intercellular communication, particularly gap junction proteins. Thus, the objective of this study is to explore the aspect of gap junction intercellular communication in canine mammary carcinoma, non-cancerous (CMEC) and cancerous (CMT12, CMT27, and CF41.Mg) cells, and patient-derived tumors. Both non-cancerous and cancerous mammary cells express connexins 26 and 43 using immunofluorescence; however, the level of expression is significantly different in quantitative analysis using western blot in which connexin 43 in both CMT12 and CMT27 is significantly decreased compared to CMEC. Furthermore, a decrease of gap junction capacity in CMT12 and CMT27 was observed compared to CMEC. Immunostaining of CMT27-xenograft tumors revealed positive Cx26 and negative Cx43 expression. Similarly, immunostaining of spontaneous canine mammary tumors revealed that Cx26 is present in all tumors while Cx43 is present in 25% of tumors. Overall, the study provides for the first time that a differential pattern of connexin expression exists between non-cancerous and cancerous mammary cells in dogs. This study will pave the path for further in vitro work of connexins in comparative canine models and possibly allow for novel therapeutics to be developed.

Podium Session 1: Prostate Cancer June 26, 2016 1050–1150

Project description:Introduction and Objectives: The phase 2 TERRAIN trial compared the efficacy and safety of enzalutamide (ENZA) vs. bicalutamide (BIC) in patients (pts) with metastatic castration-resistant prostate cancer who had progressed on luteinizing hormone-releasing hormone agonist/antagonist therapy or after bilateral orchiectomy while maintaining castration therapy during the study. An age effect analysis was pre-specified to investigate the efficacy and safety of ENZA vs. BIC. Results are presented in younger (<75 years) and older (≥75 years) pts in the TERRAIN population. Methods: In this double-blind study in North America and Europe, pts were randomized 1:1 to ENZA 160 mg/day or BIC 50 mg/day. The primary efficacy endpoint was centrally assessed progression-free survival (PFS) and a secondary efficacy endpoint was time to prostate-specific antigen (PSA) progression. Results: 184 pts were randomized to ENZA and 191 pts to BIC. 126 (68.5%) and 119 (62.3%) pts were <75, and 58 (31.5%) and 72 (37.7%) pts were ≥75, in the ENZA and BIC arms, respectively. PFS was significantly improved with ENZA vs. BIC in pts <75 years (median 16.6 vs. 5.8 months; HR 0.38 (95% CI 0.27, 0.52) and pts ≥75 years (median 13.8 vs. 6.4 months; HR 0.59 (95% CI 0.37, 0.92). Median time to PSA progression was similarly significantly improved with ENZA vs. BIC in younger (median 22.1 vs. 8.2 months; HR 0.27 (95% CI 0.18, 0.40) and older pts (median 16.6 vs. 5.8 months; HR 0.33 (95% CI 0.19, 0.57). Adverse events (AEs) with ENZA were more frequent in older pts (98.3%) vs. younger pts (92.8%), but a similar distribution of treatment-related AEs between treatment arms was observed in either age group. Conclusions: ENZA had greater efficacy than BIC regardless of age, with superior PFS and time to PSA progression. ENZA showed safety consistent with its known safety profile in both age subgroups.
