    Abstract: To provide precise age-specific risk estimates of cancers other than female breast and ovarian cancers associated with pathogenic variants (PVs) in BRCA1 and BRCA2 for effective cancer risk management. METHODS We used data from 3,184 BRCA1 and 2,157 BRCA2 families in the Consortium of Investigators of Modifiers of BRCA1/2 to estimate age-specific relative (RR) and absolute risks for 22 first primary cancer types adjusting for family ascertainment. RESULTS BRCA1 PVs were associated with risks of male breast (RR = 4.30; 95% CI, 1.09 to 16.96), pancreatic (RR = 2.36; 95% CI, 1.51 to 3.68), and stomach (RR = 2.17; 95% CI, 1.25 to 3.77) cancers. Associations with colorectal and gallbladder cancers were also suggested. BRCA2 PVs were associated with risks of male breast (RR = 44.0; 95% CI, 21.3 to 90.9), stomach (RR = 3.69; 95% CI, 2.40 to 5.67), pancreatic (RR = 3.34; 95% CI, 2.21 to 5.06), and prostate (RR = 2.22; 95% CI, 1.63 to 3.03) cancers. The stomach cancer RR was higher for females than males (6.89 v 2.76; P = .04). The absolute risks to age 80 years ranged from 0.4% for male breast cancer to approximately 2.5% for pancreatic cancer for BRCA1 carriers and from approximately 2.5% for pancreatic cancer to 27% for prostate cancer for BRCA2 carriers. CONCLUSION In addition to female breast and ovarian cancers, BRCA1 and BRCA2 PVs are associated with increased risks of male breast, pancreatic, stomach, and prostate (only BRCA2 PVs) cancers, but not with the risks of other previously suggested cancers. The estimated age-specific risks will refine cancer risk management in men and women with BRCA1/2 PVs.

    Abstract: 566 Background: The Asia-Pacific, multicenter, nonrandomized, phase II APEC study previously reported that first-line therapy for pts with KRAS ex 2 wt mCRC consisting of C once every 2 weeks combined with FOLFOX or FOLFIRI achieved efficacy and safety profiles comparable to those reported in analogous pivotal studies involving weekly C. This final analysis presents OS data from the KRAS wt intent-to-treat (ITT) population, as well as subgroup efficacy analyses stratified by BRAF, PIKC3A, and all RAS mutation status. Methods: Eligible pts received C once every 2 weeks (day 1 of each cycle, 500 mg/m 2 ) with FOLFOX or FOLFIRI (investigator’s choice). Study treatment continued until disease progression, dose-limiting toxicity or consent withdrawal. The primary endpoint was best confirmed overall response as assessed by RECIST 1.0; progression-free survival (PFS) and OS were secondary endpoints. In the evaluable populations, the status of BRAF, PIK3CA, and all RAS mutations was assessed retrospectively by pyrosequencing. Results: 42 months after the last patient was enrolled, median OS in the KRAS wt population was 26.8 months (Table). There were no unexpected safety findings. Additional biomarker results—including objective response rate (ORR), PFS, and OS subgroup analyses stratified on BRAF, PIKC3A, and all RAS mutation status—will be presented. Conclusions: The observed median OS of 26.8 months in the KRAS wt population is comparable to that reported in prior pivotal studies involving weekly C plus FOLFOX or FOLFIRI in the first line. These results suggest that C plus FOLFOX or FOLFIRI in a once-every-2-weeks regimen is active and tolerable as first-line therapy in this Asia-Pacific study population and a convenient alternative to weekly administration. Clinical trial information: NCT00778830. [Table: see text]

    Prediction of patient-reported bowel quality of life (QOL) after dose-escalated radiation therapy (RT) for prostate cancer by rectal dosimetry.
    American Society of Clinical Oncology (ASCO) ; 2013

    Abstract: 84 Background: Rectal dose-volume histogram (DVH) parameters and a consensus normal tissue complication probability (NTCP) model predict physician scored toxicity but have not been well studied for patient reported outcomes (PRO) following external beam RT for prostate cancer. Methods: PRO were prospectively collected at baseline and 12 month intervals by expanded prostate cancer index composite (EPIC) for 98 patients from 2004-2009. Linear regression modeling for bowel score at 1 and 2 years was performed using pre-treatment bowel score and DVH parameters [V 80 (% of rectal volume 〉 80 Gy), V 75 , V 70 , V 50 , V 25 , and NTCP]. Results: Median RT dose was 78 Gy with image-guidance in 81%, intensity-modulation in 72%, and pelvic RT in 11%. Rectal DVH parameters are presented in the Table. Pretreatment and 2 year PRO were available for 92% of patients. The mean pretreatment bowel summary score declined from 96.0 (sd 8.0) to 91.8 (13.5) at 2 years. Acute proctitis (grade 1-2) during RT was associated with a decline in 2 year bowel QOL, while acute diarrhea (grade 1-2) was not. At 2 years 63% of patients had a decline 〈 4 points while the remainder had a mean decline of 15.9 (14.2) with 4-6 points having been defined as the minimal clinically significant change. Linear regression modeling, adjusted for pretreatment bowel function, revealed an association between increasing V dose , NTCP and bowel QOL (Table). Akaike information criterion analysis followed by leave-one-out cross validation, indicated that V 75 provided the best predictive model for 2 year bowel QOL followed by NTCP and V 70 . Conclusions: Most previous studies have highlighted V 70 for toxicity (such as rectal bleeding). The association with V 75 and rectal QOL has not been previously reported and supports potential changes in how prostate plans are designed to maintain QOL. This is also the first validation of a consensus NTCP model for bowel QOL. [Table: see text]

    Abstract: To determine if obesity is associated with higher prostate specific antigen recurrence rates after radical prostatectomy (RP), and to explore racial differences in body mass index (BMI) as a potential explanation for the disparity in outcome between black and white men. Patients and Methods A retrospective, multi-institutional pooled analysis of 3,162 men undergoing RP was conducted at nine US military medical centers between 1987 and 2002. Patients were initially categorized as obese (BMI ≥ 30 kg/m 2 ), overweight (BMI 25 to 30 kg/m 2 ), or normal (BMI ≤ 25 kg/m 2 ). For analysis, normal and overweight groups were combined (BMI 〈 30 kg/m 2 ) and compared with the obese group (BMI ≥ 30 kg/m 2 ) with regard to biochemical recurrence (prostate-specific antigen ≥ 0.2 ng/mL) after RP. Results Of 3,162 patients, 600 (19.0%) were obese and 2,562 (81%) were not obese. BMI was an independent predictor of higher Gleason grade cancer (P 〈 .001) and was associated with a higher risk of biochemical recurrence (P = .027). Blacks had higher BMI (P 〈 .001) and higher recurrence rates (P = .003) than whites. Both BMI (P = .028) and black race (P = .002) predicted higher prostate specific antigen recurrence rates. In multivariate analysis of race, BMI, and pathologic factors, black race (P = .021) remained a significant independent predictor of recurrence. Conclusion Obesity is associated with higher grade cancer and higher recurrence rates after RP. Black men have higher recurrence rates and greater BMI than white men. These findings support the hypothesis that obesity is associated with progression of latent to clinically significant prostate cancer (PC) and suggest that BMI may account, in part, for the racial variability in PC risk.

    Abstract: 616 Background: We report our experience with next-generation sequencing to characterize the prevalence and genomic landscape of actionable genomic alterations in renal cell carcinoma (RCC). Methods: A query of our institutional clinical sequencing database was performed to include tumor samples sequenced across all cancers. Actionable alterations with clinical or biologic evidence supporting an association with response to targeted therapy were stratified by level of evidence using an oncology knowledge database (OncoKB). Results: Data from 35,668 patients was included, and the 15 cancer types with the highest prevalence of actionable alterations were selected for subsequent analysis (28,027 patients). Of these cancers, RCC ranked 13th in prevalence of actionable alterations. Of 708 RCC samples included, 259 (37%) were from metastatic sites. However, of the remaining 449 primary samples, 208 (29%) belonged to patients who had metastatic disease at the time of sequencing. Although 69% of patients with any RCC harbored at least one known oncogenic mutation, only 90/687 (13%) harbored alterations for which compelling clinical data currently exist to justify the use of a standard or an investigational agent (levels of evidence 1 to 3B). This represents an increase from the previously reported prevalence (5% in 2017). The most common histologic subtype, clear cell RCC harbored the vast majority of actionable alterations (52/421; 12%). Regarding the specific genes that harbor these alterations, 31 level 2A alterations were identified, all of which were TSC1/TSC2 mutations; 30 level 2B alterations were identified, of which PIK3CA (22) and BRCA1/BRCA2 (5) mutations were most common; 11 level 3A alterations, all of which were MTOR mutations, and 8 level 3B alterations, of which AKT1 (4) mutation was most common. Conclusions: Although the prevalence of actionable mutations in RCC seems to have doubled in recent years, the role of genetic testing in identifying candidates for targeted therapy in RCC is currently limited relative to other cancer types, emphasizing the need for additional research in this area to further inform targeted therapy decisions.

    Abstract: Neoadjuvant gemcitabine and cisplatin (GC) followed by radical cystectomy (RC) is standard for patients with muscle-invasive bladder cancer (MIBC). On the basis of the activity of atezolizumab (A) in metastatic BC, we tested neoadjuvant GC plus A for MIBC. METHODS Eligible patients with MIBC (cT2-T4aN0M0) received a dose of A, followed 2 weeks later by GC plus A every 21 days for four cycles followed 3 weeks later by a dose of A before RC. The primary end point was non–muscle-invasive downstaging to 〈 pT2N0. RESULTS Of 44 enrolled patients, 39 were evaluable. The primary end point was met, with 27 of 39 patients (69%) 〈 pT2N0, including 16 (41%) pT0N0. No patient with 〈 pT2N0 relapsed and four (11%) with ≥ pT2N0 relapsed with a median follow-up of 16.5 months (range: 7.0-33.7 months). One patient refused RC and two developed metastatic disease before RC; all were considered nonresponders. The most common grade 3-4 adverse event (AE) was neutropenia (n = 16; 36%). Grade 3 immune-related AEs occurred in five (11%) patients with two (5%) requiring systemic steroids. The median time from last dose of chemotherapy to surgery was 7.8 weeks (range: 5.1-17 weeks), and no patient failed to undergo RC because of AEs. Four of 39 (10%) patients had programmed death-ligand 1 (PD-L1)–positive tumors and were all 〈 pT2N0. Of the patients with PD-L1 low or negative tumors, 23 of 34 (68%) achieved 〈 pT2N0 and 11 of 34 (32%) were ≥ pT2N0 ( P = .3 for association between PD-L1 and 〈 pT2N0). CONCLUSION Neoadjuvant GC plus A is a promising regimen for MIBC and warrants further study. Patients with 〈 pT2N0 experienced improved relapse-free survival. The PD-L1 positivity rate was low compared with published data, which limits conclusions regarding PD-L1 as a predictive biomarker.

    Abstract: 5007 Background: The immuno-oncology (I-O) combination nivolumab + ipilimumab (NIVO+IPI) is approved for first-line (1L) and NIVO is approved for second-line treatment post TKI therapy in aRCC. The open-label, randomized, phase 2 Fast Real-Time Assessment of Combination Therapies in Immuno-Oncology (FRACTION-RCC; NCT02996110) platform study has an adaptive design allowing rapid evaluation of I-O therapies, including NIVO+IPI or other investigational combinations. This FRACTION analysis reports preliminary outcomes with NIVO+IPI in aRCC pts after progression on checkpoint inhibitor therapy. Methods: All pts, except 1, had previously received and progressed on checkpoint inhibitor treatment. Pts received NIVO+IPI (NIVO 3 mg/kg + IPI 1 mg/kg Q3W ×4, then after 6 weeks, NIVO 480 mg Q4W), up to 2 years or until progression, toxicity, or protocol-specified discontinuation. Primary endpoints were confirmed objective response rate (ORR; per investigator using RECIST v1.1), duration of response (DOR), and progression-free survival probability at week 24. Safety outcomes were reported. Results: 46 pts were randomized to NIVO+IPI. Pts had 0 (n = 1), 1 (n = 10), 2 (n = 12), 3 (n = 10), or ≥4 (n = 13) prior lines of therapy. All pretreated pts had prior anti-PD-(L)1-, none had prior anti-CTLA-4- therapy, and 37 had prior TKI-based therapy; 45 pts progressed on anti-PD-(L)1 as the most recent therapy. Most pts had clear cell aRCC (n = 44). After a median study follow-up of 8.9 months, ORR was 15.2%; no pts achieved complete response and 7 achieved partial response. DOR ranged from 2–19+ months (n = 7); 5 pts had ongoing response. Six of 7 responders had received ≥2 prior lines of therapy. Any-grade treatment-related adverse events (AEs) were reported in 36 pts (78.3%; fatigue, rash [both 19.6%], and diarrhea [17.4%] were most common). Grade 3–4 treatment-related AEs were reported in 13 pts (28.3%; diarrhea [8.7%], ↑amylase and ↑lipase [both 6.5%] were most common). Treatment-related immune-mediated AEs of any grade were reported in 22 pts (47.8%; rash [19.6%], diarrhea [17.4%] , and ↑alanine aminotransferase [8.7%]). No treatment-related deaths were reported. Updated and expanded results with an additional 3 months of follow-up will be presented. Conclusions: These results suggest that NIVO+IPI may provide durable partial response in some pts with prior progression on checkpoint inhibitors, including some heavily pretreated pts. The safety profile of NIVO+IPI in FRACTION pts was similar to historic data in aRCC with this combination. Clinical trial information: NCT02996110 .

    Abstract: 733 Background: A phase 1b/2 clinical trial indicated that len/pembro shows promise in the treatment of renal cell carcinoma (RCC) in both PD-1/PD-L1 immune checkpoint blockade (ICB)-naïve and pretreated patients (NCT02501096). The combination is being further investigated in a phase 3 clinical trial in RCC (NCT02811861). Tumor antigen presentation depends on multiple factors, including HLA diversity, which can be measured by HLA evolutionary divergence (HED). HED quantitates the capacity of a patient’s HLA genotype to present different peptide antigens. This study is investigating the genomic components of tumor antigen presentation in ICB-naïve patients who have RCC and are treated with len/pembro. Methods: Whole exome sequencing (WES) was performed on pretreatment tumor-derived DNA. Somatic mutations, tumor mutation burden (TMB), neoantigen (NA) load, germline HLA zygosity and somatic loss of heterozygosity (LOH), and HED were correlated with objective response rate (ORR) and progression-free survival (PFS). An updated clinical cutoff was March 29, 2019. Results: Twenty four (80%) of 30 ICB-naïve patients underwent WES. A top-quartile cutoff was used. Increased mean HED was associated with improved PFS, while HLA homozygosity or LOH trended toward worse PFS. Loss-of-function mutations in PBRM1 (PBRM1 LOF) trended toward improved PFS. However, TMB and NA load were not correlated to PFS. No genomic biomarkers were correlated to ORR. Conclusions: Increased HLA diversity was associated with improved PFS, while decreased HLA diversity may be associated with worse PFS. PBRM1 mutation may be associated with improved PFS; however, TMB and NA load were not correlated to outcomes. These findings warrant further examination in larger datasets to rule out possible artifacts from multiple testing in a small cohort. Clinical trial information: NCT02811861. [Table: see text]

    Abstract: e14501 Background: Randomized studies have shown that weekly cetuximab added to first-line FOLFOX or FOLFIRI improves clinical outcome in patients (pts) with KRAS wild-type (wt) mCRC. This Asia-Pacific multicenter study investigated FOLFOX or FOLFIRI + every 2 weeks cetuximab (C) as first-line therapy in pts with KRAS wt mCRC. Methods: Eligible pts received every 2 weeks cetuximab (d1 500 mg/m 2 q14d) with, based on investigator’s choice, either FOLFOX (oxaliplatin 100 mg/m 2 , folinic acid [FA] 200 mg/m 2 L-form or 400 mg/m 2 racemic, then 5-fluorouracil [5-FU], as a 400 mg/m 2 iv bolus and a 2400 mg/m 2 infusion over 46 h) or FOLFIRI (irinotecan 180 mg/m 2 , FA 200 mg/m 2 L-form, or 400 mg/m 2 racemic, then 5-FU, as a 400 mg/m 2 iv bolus and a 2400 mg/m 2 infusion over 46 h), until disease progression, unacceptable toxicity or consent withdrawal. Primary endpoint was tumor response; assessed radiologically (RECIST 1.0) every 8 weeks. Results: Data cut-off was 86 weeks after the date of last patient included. The ITT/safety population comprised 289 pts; 65.1% received FOLFOX + C and 34.9% FOLFIRI + C. Baseline characteristics were generally well balanced. Leukocyte count 〉 10000/mm 3 was more frequent (16.5% vs 7.9%) and prior adjuvant treatment less frequent (21.3% vs 46.5%) in pts receiving FOLFOX + C. Response (CR or PR) was observed in 170 (58.8%) pts. The overall R0 resection rate was 10.0%. Survival data are not mature. Cetuximab dose intensity was 〉 80% in 77.7% (FOLFOX + C) and 74.3% (FOLFIRI + C) of pts. Most frequent grade 3/4 adverse events ( 〉 10% in either arm) were neutropenia, diarrhea, hypokalemia, neuropathy (FOLFOX + C only) and skin reactions. Conclusions: Efficacy and safety profiles of every 2 weeks cetuximab combined with FOLFOX or FOLFIRI were similar to those reported for either chemotherapy plus weekly cetuximab in pivotal studies.
