279 Background: While bacillus Calmette-Guérin (BCG) is the most effective intravesical treatment for reducing recurrence and progression for high-risk non-muscle invasive bladder cancer (NMIBC), many patients are either refractory to treatment or relapse. We assessed the efficacy and safety of rAd-IFNα/Syn 3 (Instiladrin, FKD Finland), a replication deficient recombinant adenovirus gene transfer vector, for patients with high-grade (HG) BCG refractory or relapsed NMIBC. Methods: In this open-label, US multicenter (n=13), parallel-arm Phase II study (NCT01687244), 43 patients with HG BCG refractory or relapsed NMIBC were randomized 1:1 to receive intravesical rAd-IFNα/Syn3 at 1x1011 or 3x1011viral particles/mL. Patients responding at months 3, 6, and 9 were re-treated at months 4, 7, and 10. Most patients (n=21) had a primary tumor classification of carcinoma in situ (CIS); 9 had both CIS and Ta/T1 disease and 10 had Ta/T1 disease alone. The primary endpoint was 12-month HG recurrence-free survival (RFS). All patients receiving at least one dose were included in efficacy and safety analyses. Results: Forty patients received rAd-IFNα/Syn3 (1 x 1011 vp/mL: n=21; 3 x 1011vp/mL: n=19) between November 2012 and April 2015. Fourteen patients (35.0%; 90% CI 22.6%, 49.2%) remained free of HG tumor recurrence 12 months after initial treatment. Comparable 12 month HG RFS was noted between dosage arms, as well as between patients with refractory and relapsed NMIBC. Interestingly, the 12 month HG recurrence-free survival for patients with Ta/T1-only disease was 50% (5/10). rAd-IFNα/Syn3 was well-tolerated, with no Grade 5 adverse events (AEs), one Grade 4 AE (COPD; unrelated to treatment), and no patient discontinuing treatment due to an adverse event. The most frequently reported AEs were micturition urgency (n=16), dysuria and pollakiuria (n=13 each), fatigue (n=9), and nocturia (n=10). Conclusions: rAd-IFNα/Syn3 was well tolerated and demonstrated promising efficacy for patients with HG NMIBC after BCG therapy who are unable or unwilling to undergo radical cystectomy. A phase III trial utilizing this novel agent is ongoing. Clinical trial information: 01687244.

Abstract Identifying genetic variants with pleiotropic associations can uncover common pathways influencing multiple cancers. We took a two-stage approach to conduct genome-wide association studies for lung, ovary, breast, prostate, and colorectal cancer from the GAME-ON/GECCO Network (61,851 cases, 61,820 controls) to identify pleiotropic loci. Findings were replicated in independent association studies (55,789 cases, 330,490 controls). We identified a novel pleiotropic association at 1q22 involving breast and lung squamous cell carcinoma, with eQTL analysis showing an association with ADAM15/THBS3 gene expression in lung. We also identified a known breast cancer locus CASP8/ALS2CR12 associated with prostate cancer, a known cancer locus at CDKN2B-AS1 with different variants associated with lung adenocarcinoma and prostate cancer, and confirmed the associations of a breast BRCA2 locus with lung and serous ovarian cancer. This is the largest study to date examining pleiotropy across multiple cancer-associated loci, identifying common mechanisms of cancer development and progression.

AbstractRobotic surgical techniques are now being applied in the setting of retroperitoneal lymphadenectomy (RPLND) for testicular cancer. While laparoscopic RPLND has not been widely accepted, reports of robot assisted RPLND (RARPLND) are emerging. This manuscript will review the application of RPLND for testicular cancer, evolution of minimally invasive techniques, the controversies, and current status of RARPLND. J. Surg.

The purpose of the RAZOR (randomized open vs robotic cystectomy) study is to compare open radical cystectomy ( ORC ) vs robot‐assisted RC ( RARC ), pelvic lymph node dissection ( PLND ) and urinary diversion for oncological outcomes, complications and health‐related quality of life ( HRQL ) measures with a primary endpoint of 2‐year progression‐free survival ( PFS ). RAZOR is a multi‐institutional, randomized, non‐inferior, phase III trial that will enrol at least 320 patients with T 1– T 4, N 0– N 1, M 0 bladder cancer with ≈160 patients in both the RARC and ORC arms at 15 participating institutions. Data will be collected prospectively at each institution for cancer outcomes, complications of surgery and HRQL measures, and then submitted to trial data management services Cancer Research and Biostatistics ( CRAB ) for final analyses. To date, 306 patients have been randomized and accrual to the RAZOR trial is expected to conclude in 2014. In this study, we report the RAZOR trial experimental design, objectives, data safety, and monitoring, and accrual update. The RAZOR trial is a landmark study in urological oncology, randomizing T 1– T 4, N 0– N 1, M 0 patients with bladder cancer to ORC vs RARC , PLND and urinary diversion. RAZOR is a multi‐institutional, non‐inferiority trial evaluating cancer outcomes, surgical complications and HRQL measures of ORC vs RARC with a primary endpoint of 2‐year PFS . Full data from the RAZOR trial are not expected until 2016–2017.

Abstract Background: Colorectal cancer (CRC) in densely affected families without Lynch Syndrome may be due to mutations in undiscovered genetic loci. Familial linkage analyses have yielded disparate results; the use of exome sequencing in coding regions may identify novel segregating variants. Methods: We completed exome sequencing on 40 affected cases from 16 multicase pedigrees to identify novel loci. Variants shared among all sequenced cases within each family were identified and filtered to exclude common variants and single-nucleotide variants (SNV) predicted to be benign. Results: We identified 32 nonsense or splice-site SNVs, 375 missense SNVs, 1,394 synonymous or noncoding SNVs, and 50 indels in the 16 families. Of particular interest are two validated and replicated missense variants in CENPE and KIF23, which are both located within previously reported CRC linkage regions, on chromosomes 1 and 15, respectively. Conclusions: Whole-exome sequencing identified DNA variants in multiple genes. Additional sequencing of these genes in additional samples will further elucidate the role of variants in these regions in CRC susceptibility. Impact: Exome sequencing of familial CRC cases can identify novel rare variants that may influence disease risk. Cancer Epidemiol Biomarkers Prev; 22(7); 1239–51. ©2013 AACR.
