414 Background: Recent studies suggest an “obesity paradox” in renal cell carcinoma (RCC), in which obese people are more likely to be diagnosed with RCC, but are less likely to die of the disease. We studied the association of body mass index (BMI) with risk of both total and fatal RCC in two large prospective cohorts. Methods: The Nurses’ Health Study (NHS) consists of 117,097 women followed since 1976, and the Health Professionals Follow-up Study (HPFS) consists of 48,268 men followed since 1986. Height and weight were reported at baseline and updated biennially through 2008, with disease follow-up through 2010. We used multivariable Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the incidence of both total and fatal pathology-confirmed RCC by BMI immediately prior to diagnosis. Models were adjusted for diabetes, hypertension, smoking, alcohol intake, NSAID use, physical activity, and parity in women. Results: We confirmed 349 cases of RCC, including 103 fatal cases, in NHS, and 226 cases in HPFS, with 46 fatal cases. Compared to women with normal BMI (18.5-24.9 kg/m2) immediately prior to diagnosis, obese women (BMI≥30) had an increased risk of RCC (HR 1.38, 95% CI: 1.03-1.84, p-trend=0.004), adjusting for possible confounders. The HR for fatal RCC was similar but not statistically significant (HR 1.35, 95% CI: 0.79-2.29, p-trend=0.22). Obese men had a non-significantly increased risk of RCC (HR 1.45, 95% CI: 0.96-2.21, p-trend=0.05), with a significantly increased risk of fatal RCC (HR 2.56, 95% CI: 1.11-5.90, p-trend=0.13). Among women, the associations with baseline BMI (1976) were somewhat stronger (HR 1.88, 95% CI: 1.36-2.61, p-trend<0.0001 for total; HR 1.98, 95% CI: 1.07-3.66, p-trend=0.002 for fatal). For men the association with baseline BMI (1986) was weaker for fatal RCC (HR 1.34, 95% CI: 0.50-3.58, p-trend=0.27). Conclusions: Our results support that obesity is a risk factor for RCC incidence and also suggest that it is adversely associated with fatal RCC. These results are stronger for women than for men, though this may be due to the lower number of cases among men.

Statin Use

679 Background: Evidence on statin use and incidence of renal cell carcinoma (RCC) is mixed. Previous results from the Nurses’ Health Study (NHS) and Health Professionals Follow-up Study (HPFS) found a suggestive protective effect in women but not in men (Liu et al, Cancer 2012). We conducted an updated analysis of statin use and risk of total and fatal RCC in the NHS, HPFS, and NHS 2 cohorts, with more than twice as many cases. Methods: We examined the associations between statin use and risk of RCC from 1990 to 2016 in HPFS (men), 1994 to 2016 in NHS (women), and 1999 to 2015 in NHS 2 (women). Information on statin use was collected every two years. We used Cox proportional hazards models, adjusting for known and suspected risk factors, to estimate hazard ratios (HR) and 95% confidence intervals (CI) for use of statins and risk of total and fatal RCC, RCC by stage at diagnosis, and clear cell RCC. We pooled results across cohorts using a random effects model. Results: We documented 661 cases of RCC (310 in HPFS, 255 in NHS, 96 in NHS 2), of which 132 (20%) were fatal. Of the 661 cases, 458 (69%) were clear cell. The pooled multivariable HR for total RCC was 1.01 (95% CI 0.84-1.21) for current statin use, updated over time. Current use was not associated with risk of fatal, advanced (stage T3 or higher), or localized (stage T1 or T2) disease. There were no associations between duration of statin use and risk of RCC; compared to never users, those with less than four years of total use had an HR of 0.91 (95% CI 0.71-1.18), and those with four or more years of use had an HR of 1.03 (95% CI 0.84-1.27). Among men, statin use was associated with increased risk of clear cell RCC (HR for current use: 1.48, 95% CI 1.04-2.11; HR for 4 or more years of use: 1.58, 95% CI 1.05-2.36). Statins were not associated with risk of clear cell RCC in women (HR for current use: 0.77, 95% CI 0.58-1.03; p-value for heterogeneity across cohorts = 0.02). Conclusions: Overall, statin use was not associated with risk of RCC in three large, prospective cohorts of US women and men. Statin use was associated with increased risk of clear cell RCC among men.

Incident Cases

677 Background: Acrylamide, which has been classified as a probable human carcinogen, is formed during the processing and cooking of many commonly consumed, carbohydrate-rich foods. Accumulating evidence suggests that dietary intake of acrylamide intake is not associated with the risk of most cancers in humans. A meta-analysis of five epidemiological studies, however, found a suggestion of an increased risk of kidney cancer with higher acrylamide intakes. We investigated this association in two large, prospective cohorts. Methods: Acrylamide intake was calculated from food frequency questionnaires completed every four years in the Nurses’ Health Study (NHS; 1980-2014; n = 88,770) and the Health Professionals Follow-up Study (HPFS; 1986-2014; n = 47,802). Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association with renal cell carcinoma (RCC), adjusting for known and suspected risk factors. Results: We documented 569 incident cases of RCC during follow-up, 337 in women and 232 in men. There was no association between cumulative average acrylamide intake and risk of RCC risk in women (HR for top versus bottom quartile of intake: 0.85; 95% CI: 0.62-1.18; p-value for linear trend across quartiles: 0.42) or men (HR: 1.09; 95% CI: 0.77-1.55; p-trend: 0.96). Baseline acrylamide intake was also unassociated with RCC risk. Acrylamide intake was not associated with risk of fatal RCC, risk among never-smokers, or risk of clear cell RCC. Intake of foods and food groups that are the major contributors to acrylamide intake – breads, baked goods, breakfast cereal, potatoes, and coffee – were likewise not associated with risk of total or fatal RCC in women or in men. Conclusions: Dietary acrylamide was not associated with the risk of RCC in two long-term, prospective cohorts of women and men with updated measures of dietary intakes. This analysis of renal cell carcinoma adds to the body of evidence that dietary acrylamide is not an important risk factor for cancer in humans.

Underlying Mechanisms

Elevated Renal cell carcinoma (RCC) risk has been associated with the use of several antihypertensive medications but has not yet been elucidated in the populations prescribed alpha-1 blockers that are commonly used in the treatment of hypertension and lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS-BPH). The aim of the present study was to investigate the association between alpha-1 blocker use and the risk of developing RCC using a nationwide population-based database in Taiwan. Patients who were treated with alpha-1 blockers for at least 28 days were identified through the Taiwan National Health Insurance Research Database from 2000 to 2010. The unexposed participants were matched with the exposed cases according to age, sex, and index year at a ratio of 3:1. Cox proportional hazards regression, stratified by sex and comorbidities and adjusted for age, was performed to estimate hazard ratios (HRs) for the risk of subsequent RCC. Among 2,232,092 subjects, patients who received alpha-1 blocker treatment had a higher risk of RCC than the unexposed group. Taking into account hypertension and BPH, the adjusted HR was significantly higher in male alpha-1 blocker users who had no BPH and either the presence (HR: 1.63, 95% confidence interval [CI] = 1.22–2.18) or absence (HR: 2.31, 95% CI = 1.40–3.81) of hypertension than in men not receiving these drugs. Taken together, male alpha-1 blocker users who had no comorbidity of BPH exhibited an increased risk for developing RCC independent of hypertension. Further study is warranted to elucidate the underlying mechanisms of this association.

444 Background: Obesity has been associated with increased risk of renal cell carcinoma (RCC). However the prognostic significance of obesity in the survival of patients with RCC is still undefined. Our study examined prognostic significance of obesity on the overall survival of patients (pts) with RCC in community hospital settings. Methods: A retrospective review of pts diagnosed with RCC between 1995 and 2008 in a community hospital setting was done. Pts with additional malignancies, lymphoma of the kidneys and no follow up data were excluded from the study. Demographics, body mass index(BMI) at diagnoses, pathology, disease stage, operative note, and subsequent follow up data were reviewed. The WHO BMI classification was used to group pts into Underweight (UW) < 18.5; Normal (NL): 18.5-24.99; Pre-obese (PO): 25-29.99; Obese I (Ob I): 30-34.99; Obese II (Ob II): 35-39.99; Obese III (Ob III): ≥40. The primary outcome was 3 years overall survival. Results: A total Of 205 pts reviewed, 127 (62.3%) were males, 176 (85.9%) were Caucasians. The median age of the study population was 65 (22-91). The prevalence of obesity was 42.3% in the study population; 46.2% in females and 39% in males (p=0.19). The median BMI was 28.8 (16-54.6). Pts were categorized based on their BMI as: UW (1.5%), NL (21.4%), PO (34.7%), Ob I (26%), Ob II (8.2%), and Ob III (8.2%). Clear Cell was the commonest histology (79%). Stage I was seen in 53.9%, II in 23.5%, III in 13.7% and IV in 8.8% of the study population. The 3 year overall survival for the study population was 67.3% (95% CI: 60.4-73.7). The 3-year overall survival of obese and non obese pts with RCC were 66.4% and 69.5% respectively (p=0.34). There was no difference in the 3-year overall survival of patient in the BMI groupings: (UW: 66.7%, NW: 59%, Pre-Ob: 70.6%, Obese I: 70%, II: 75%, III: 62.5%; p=0.8). Conclusions: Our study didn’t find any association between BMI and 3 year overall survival in pts with RCC. Larger randomized trials are warranted before excluding the negative impact of obesity in the overall survival of pts with renal cell carcinoma.

Analgesic Use

588 Background: The relationship between the widely used analgesics (i.e., aspirin, other nonsteroidal anti-inflammatory drugs (NSAID), and acetaminophen) and risk of total and lethal renal cell cancer remains unclear. Methods: We examined the associations between analgesic use and risk of renal cell cancer overall and by subtypes, in the Nurses’ Health Study (NHS) and the Health Professionals Follow-up Study (HPFS). We collected information on aspirin, other non-aspirin NSAIDs, and acetaminophen in 1990 in the NHS and in 1986 in the HPFS, and every 2 years thereafter. We used Cox proportional hazards models, controlling for other known and suspected risk factors, to examine the associations between baseline and duration of use of each analgesic and risk of total renal cell cancer, lethal renal cell cancer (resulted in death due to disease), as well as clear cell renal cell cancer. We pooled results using a random-effects model. Results: During follow-up of 22 years among 77,527 women and 26 years among 45,913 men, we documented 438 cases of renal cell cancer (230 in women and 208 in men), of which 106 were fatal (56 in women and 40 in men) and 300 were clear cell (165 in women and 135 in men). The pooled multivariable relative risks (RRs) for total renal cell cancer were 1.13 (95% CI: 0.91-1.39) for aspirin use, 1.34 (95% CI: 1.03-1.75) for non-aspirin NSAID use, and 1.07 (95% CI: 0.80-1.44) for acetaminophen use. Similar results were observed for lethal renal cell cancer and clear cell renal cell cancer. Importantly, longer duration of non-aspirin NSAID use was associated with an increased risk of renal cell cancer. The pooled (all p-heterogeneity > 0.05) multivariable RRs for total renal cell cancer were 1.23 (95% CI: 0.94-1.62) for non-aspirin NSAID users of 4-10 years and 1.81 (95% CI: 1.21-2.72) for over 10 years. The corresponding RRs were 1.91 (95% CI: 1.04-3.49) and 3.97 (95% CI: 1.46-10.83) for lethal renal cell cancer, and 1.36 (95% CI: 0.99-1.88) and 1.58 (95% CI: 0.94-2.63) for clear cell renal cell cancer. Conclusions: Our findings support a significant positive association between non-aspirin NSAID use and risk of developing renal cell cancer, especially the lethal form.

PURPOSE This report is a patterns-of-failure analysis of resected renal cell carcinoma (RCC) performed to determine the relative incidences of local failure (LF) and distant failure, to identify the pathologic features predicting for each using a multivariate analysis, and to assess the relative impact of each form of failure on overall survival (OS). In this way, the potential value of and selection of patients for adjuvant local and/or systemic therapy can be better evaluated. MATERIALS AND METHODS The records of 172 patients with unilateral, nonmetastatic RCC who were treated with definitive surgery between 1978 and 1988, and who had a minimum follow-up duration of 1 year, were identified through the Memorial Sloan-Kettering tumor registry. Distribution by stage included T1, 10 patients; T2, 102; T3a, 32; T3b, 27; and T4, one. The incidences of positive lymph nodes (LNs) and positive margins were 5.8% and 6.4%, respectively. RESULTS LF developed in only six patients, yielding a 7-year actuarial incidence of 5%. In this subset, four patients developed distant metastases (DM), three occurring concurrently with or before LF. DM developed in 30 patients, yielding a 7-year actuarial incidence of 26%. Among the variables that had an impact on the development of DM according to univariate log-rank tests, only positive LNs (P = .026) and renal vein extension (P = .001) remained as significant independent prognosticators. The overall 7-year actuarial survival rate was 80%. Eleven patients died of RCC during follow-up, nine of whom (82%) died of metastatic disease. CONCLUSION LF is rare following surgical management of RCC, and shows no clear causal relationship with the development of DM. Patients die of DM, and not LF. These data do not support the role of adjuvant radiation therapy in this disease. Patients with LN involvement or renal vein extension have a significantly increased risk for developing DM, and are therefore appropriate candidates for trials investigating systemic therapy.

Abstract Background Coffee consumption has been associated with a reduced risk of some cancers, but the evidence for renal cell carcinoma (RCC) is inconclusive. We investigated the relationship between coffee and RCC within a large cohort. Methods Coffee intake was assessed at baseline in the National Institutes of Health–American Association of Retired Persons Diet and Health Study. Among 420 118 participants eligible for analysis, 2674 incident cases were identified. We fitted Cox-regression models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for coffee consumption vs non-drinkers. Results We observed HRs of 0.94 (95% CI 0.81, 1.09), 0.94 (0.81, 1.09), 0.80 (0.70, 0.92) and 0.77 (0.66, 0.90) for usual coffee intake of &lt;1, 1, 2–3 and ≥4 cups/day, respectively (Ptrend = 0.00003). This relationship was observed among never-smokers (≥4 cups/day: HR 0.62, 95% CI 0.46, 0.83; Ptrend = 0.000003) but not ever-smokers (HR 0.85, 95% CI 0.70, 1.05; Ptrend = 0.35; Pinteraction = 0.0009) and remained in analyses restricted to cases diagnosed &gt;10 years after baseline (HR 0.65, 95% CI 0.51, 0.82; Ptrend = 0.0005). Associations were similar between subgroups who drank predominately caffeinated or decaffeinated coffee (Pinteraction = 0.74). Conclusion In this investigation of coffee and RCC, to our knowledge the largest to date, we observed a 20% reduced risk for intake of ≥2 cups/day vs not drinking. Our findings add RCC to the growing list of cancers for which coffee consumption may be protective.

Renal cell carcinoma (RCC) is the third most frequent urinary malignancy and one of the most lethal. Current diagnostic and follow-up techniques are harmful and unspecific in low-grade tumors. Novel minimally invasive markers such as urine microRNAs (miRNAs) are under study. However, discrepancies arise among studies in part due to lack of consent regarding normalization. We aimed to identify the best miRNA normalizer for RCC studies performed in urine samples together with a miRNA profile with diagnostic value and another for follow-up. We evaluated the performance of 120 candidate miRNAs in the urine of 16 RCC patients and 16 healthy controls by RT-qPCR followed by a stability analysis with RefFinder. In this screening stage, miR-20a-5p arose as the most stably expressed miRNA in RCC and controls, with a good expression level. Its stability was validated in an independent cohort of 51 RCC patients and 32 controls. Using miR-20a-5p as normalizer, we adjusted and validated a diagnostic model for RCC with three miRNAs (miR-200a-3p, miR-34a-5p and miR-365a-3p) (AUC = 0.65; Confidence Interval 95% [0.51, 0.79], p = 0.043). let-7d-5p and miR-205-5p were also upregulated in patients compared to controls. Comparing RCC samples before surgery and fourteen weeks after, we identified let-7d-5p, miR-152-3p, miR-30c-5p, miR-362-3p and miR-30e-3p as potential follow-up profile for RCC. We identified validated targets of most miRNAs in the renal cell carcinoma pathway. This is the first study that identifies a robust normalizer for urine RCC miRNA studies, miR-20a-5p, which may allow the comparison of future studies among laboratories. Once confirmed in a larger independent cohort, the miRNAs profiles identified may improve the non-invasive diagnosis and follow-up of RCC.
