Surveillance for the management of small renal masses: Utilization and outcomes in a population-based cohort.

343 Background: Small renal masses (SRM) are comprised of a heterogeneous group of tumors with some having malignant potential. Although surgery is the standard treatment for SRMs, emerging data suggests that surgery in the elderly or morbidly ill patients may be unnecessary and may adversely impact non-oncologic outcomes. We analyzed a population-based cohort of patients to identify predictors of surveillance and assess the impact of surveillance on overall survival, kidney cancer-specific survival and cardiovascular (CV) events, compared with surgery. Methods: From surveillance, epidemiology, and end results (SEER) cancer registry data linked with Medicare claims, we performed a retrospective cohort study of patients 66 years of age or older who received surgery or surveillance for SRM (< 4 cm) diagnosed between 2000 to 2007. Propensity score methods were used to control for potential confounders in multivariable analysis. Results: Of 8,317 patients, 5,706 (70%) underwent surgery and 2,611 (31%) underwent surveillance. The use of surveillance increased from 25% in 2000 to 37% in 2007 (p < 0.001). During a median follow-up of 58 months, 2,053 (25%) patients had at least one CV event and 2,078 (25%) patients died, including 277 (3%) who died of kidney cancer. Compared with surgery, surveillance was associated with a significantly lower risk of death from any cause (hazard ratio [HR], 0.84; CI, 0.75-0.94) and of suffering a CV event (HR, 0.79; CI 0.70-0.89), controlling for patient and disease characteristics. Kidney cancer-specific survival did not differ by treatment approach (HR, 0.89; CI, 0.66-1.21). Conclusions: There is increasing utilization of surveillance as an initial treatment strategy for patients with SRMs. For older patients with SRM, surveillance does not appear to adversely affect kidney cancer-specific survival, while surgery may be associated with CV complications and an increased risk of death from any cause. Surveillance should be considered an option for patients with SRM who are not otherwise acceptable candidates for surgical treatment.

Abstract Background: Patients (pts) with non-Hodgkins lymphoma (NHL) are at increased risk of venous thromboembolism (VTE). We and others have demonstrated increased risk of death among NHL pts with incident VTE; however, these studies were largely conducted in the pre-rituximab era. We therefore analyzed a large cohort of NHL pts in the California Cancer Registry (CCR), determined the incidence of VTE, and evaluated its effect on survival in the rituximab era. Methods: Using the CCR linked with hospital discharge and emergency department records, we identified adult NHL pts diagnosed in 2005 – 2010, excluding cases ascertained via autopsy or death certificate, and those diagnosed with acute VTE in the 2 months preceding NHL diagnosis. VTE was defined by specific ICD-9-CM codes, and Elixhauser comorbidity score, excluding lymphoma, was calculated. Cumulative incidence was calculated using the Kaplan-Meier (KM) method. Adjusted hazard ratios (aHR) of VTE and death were estimated using Cox proportional hazard models, stratified by indolent vs aggressive NHL subtype, adjusting for age, race, stage, treatment, comorbidity and prior VTE. Analyses of VTE incidence treated death as a competing risk. Cox models for death incorporated VTE as a time-dependent covariate to account for immortal time bias. Results: NHL was identified in 18,424 pts. Most (n=12,963) had aggressive NHL (1,017 mantle cell, 11,246 diffuse large B-cell or follicular grade 3, 170 lymphoblastic, 530 Burkitt), while 5,461 had indolent NHL (2,809 follicular grade 1/2, 2,652 marginal zone). Median age was 64 years (yrs) and was similar in aggressive and indolent cohorts. Men accounted for 54% (n=9926) of cases, and were more common in aggressive compared to indolent NHL (7,317 (56%) vs 2,609 (48%) respectively). Most cases (62% n=11,451) were non-Hispanic White, 4% (n=795) were African American, 21% (n=3866) Hispanic, 11% Asian (n=2013) and 1.6% unknown (n=299). The ethnic distribution was similar in aggressive and indolent NHL. Median number of reported comorbid conditions was 2. Chemotherapy was initiated in 76% (n=9791) of aggressive NHL pts and 41% (n=2250) of indolent pts. The KM cumulative incidence of first time, acute VTE in NHL pts was 4.7% (95% CI 4.4 – 5.0) and 5.3% (95% CI 4.9- 5.6) at 1 and 2 years respectively. The incidence of VTE was higher in patients with aggressive versus indolent NHL (6.5% (95% CI 6.1 - 6.9) vs 2.3% (95% CI 2.0 - 2.8) at 2 yrs respectively P<0.001), and was highest during the first 6 months after dx (Figure). In multivariable analysis of aggressive lymphoma pts, the risk of VTE was higher among pts receiving chemotherapy (Ctx) [aHR 2.3, 95% CI (1.9 – 3.0)], lower in pts with stage II NHL [aHR 0.8, 95% CI (0.6 – 1.0)] while histological subtype of aggressive NHL was not a predictor. For indolent NHL, the risk of developing acute VTE was increased among cases that received Ctx [aHR 2.3, 95% CI (1.6 – 3.4)], and cases with follicular grade 1/2 [aHR 1.6, 95% CI (1.1 – 2.3)] whereas stage was not a significant risk factor. Five year overall survival for aggressive NHL was 55% (95% CI 46 – 56) and 80% (95% CI 69 – 82) for indolent NHL. In multivariable analysis risk of incident VTE after diagnosis of NHL dx was associated with an increased risk of death (Table). Interestingly, this effect was present for only the first 2 years after dx of aggressive NHL, while the effect persisted throughout follow-up for indolent NHL. Conclusions: This large, population based study, which captured essentially all patients diagnosed with NHL in California between 2005-2010, confirms prior reports of VTE incidence in NHL patients. Pts are at highest risk early in their course, and pts undergoing chemotherapy were at increased risk. Moreover, VTE subsequent to NHL diagnosis independently increases the risk of death adjusting for other important covariates. Whereas chemoimmunotherapy has negated the effect of some previous negative prognostic factors, the adverse effect of incident VTE persists in this recent cohort.

The Impact

Melanoma metastases to the groin are frequently managed by therapeutic lymph node dissection. Evidence is lacking regarding the extent of dissection required. Thus, we sought to describe practice patterns for the use of inguinal vs. ilioinguinal dissection, as well as the perioperative/oncologic outcomes of each procedure. A mixed-methods approach was employed to evaluate surgical practice patterns. A retrospective review of three multi-site databases was carried out, together with semi-structured interviews of melanoma surgeons. A total of 347 patients who underwent dissection were reviewed. The main indications stated for adding a “deep” ilioinguinal dissection were palpable or radiologically positive disease. There was no significant difference in complications, length of stay or lymphedema between patients having inguinal vs. ilioinguinal dissection, irrespective of method of diagnosis. There was also no significant difference in recurrence, cancer-specific survival or overall survival between groups. In conclusion, ilioinguinal dissection is a safe and well-tolerated procedure, with no significant added morbidity relative to an inguinal dissection. The indications for ilioinguinal dissection currently in use produce an appropriate deep node positivity rate and ilioinguinal dissection should continue to be used selectively. Randomized data are needed to clarify the impact of ilioinguinal dissection on regional control and survival.

e16146 Background: A growing number of patients with colorectal cancer (CRC) have survived a previous cancer. Although little is known about their prognosis, this population is frequently excluded from clinical trials. We examined the impact of previous cancer on overall and cancer-specific survival in a population-based cohort of patients diagnosed with incident CRC. Methods: We identified patients aged ≥66 years and diagnosed with CRC between 2005-2015 in linked SEER-Medicare data. For patients with and without previous cancer, we estimated overall survival using Cox regression and cause-specific survival using competing risk regression, separately by CRC stage, while adjusting for numerous covariates and competing risk of death from previous cancer, other causes, or the incident CRC. Results: Of 112,769 CRC patients diagnosed with incident CRC, 15,935 (14.1%) had a previous cancer – most commonly prostate (32.9%) or breast (19.4%) cancer, with many 7505 (47.1%) diagnosed ≤5 years of CRC. For all CRC stages except IV in which there was no significant difference in survival, patients with previous cancer had modestly worse overall survival (hazard ratios from fully adjusted models range from 1.11-1.28 across stages; see Table). This survival disadvantage was driven by deaths due to previous cancer and other causes. Notably, most patients with previous cancer had improved CRC-specific survival. Conclusions: CRC patients who have survived a previous cancer have generally worse overall survival but superior CRC-specific survival. This evidence should be considered concurrently with concerns about trial generalizability, low accrual, and heterogeneity of participants when determining exclusion criteria. [Table: see text]

SUMMARY To define the incidence of postoperative venous thromboembolism (VTE) and effects of chemotherapy in a population undergoing surgery for esophagogastric cancer. This population-based cohort study used linked primary (Clinical Practice Research Datalink) and secondary (Hospital Episode Statistics) care data from England to identify subjects undergoing esophageal or gastric cancer surgery between 1997 and 2014. Exposures included age, comorbidity, smoking, body mass index, and chemotherapy. Crude rates and adjusted hazard ratios (HRs) were calculated for rate of first postoperative VTE using Cox regression models. The cumulative incidence of VTE at 1 and 6 months was estimated accounting for the competing risk of death from any cause. Of the 2,452 patients identified, 1,012 underwent gastrectomy (41.3%) and 1,440 esophagectomy (58.7%). Risk of VTE was highest in the first month, with absolute VTE rates of 114 per 1,000 person-years (95% CI 59.32–219.10) following gastrectomy and 172.73 per 1,000 person-years (95% CI 111.44–267.74) following esophagectomy. Neoadjuvant and adjuvant chemotherapy was associated with a six-fold increased risk of VTE following gastrectomy, HR 6.19 (95% CI 2.49–15.38). Cumulative incidence estimates of VTE at 6 months following gastrectomy in patients receiving no chemotherapy was 1.90% and esophagectomy 2.21%. However, in those receiving both neoadjuvant and adjuvant chemotherapy, cumulative incidence following gastrectomy was 10.47% and esophagectomy, 3.9%. VTE rates are especially high in the first month following surgery for esophageal and gastric cancer. The cumulative incidence of VTE at 6 months is highest in patients treated with chemotherapy. In this category of patients, targeted VTE prophylaxis may prove beneficial during chemotherapy treatment.

Abstract Introduction Multiple myeloma (MM) causes lytic bone lesions, osteopenia, and fractures, which increase the morbidity of MM patients. Results from small previous studies have indicated that fractures in MM have a negative effect on survival. Aims The aim of the study was to evaluate the impact of fractures on survival in MM patients diagnosed in Sweden in the years 1990-2013. Furthermore, to analyze the effect of bone fractures at MM diagnosis on subsequent survival. Methods Patients diagnosed with MM in 1990-2013 were identified from the Swedish Cancer Registry. Information on date of birth, diagnosis, and death were collected from the Registry of Total Population. Information on all fractures were retrieved from the Swedish Patient Registry. Cox regression model was used with fractures as time-dependent variables. The effect of fractures on survival was assessed for any fracture or a subtype of fracture (a specific bone fracture or ICD-coded pathologic fracture). Either first fracture or the first subtype of fracture was used in the analysis. The effect of a fracture at MM diagnosis (within 30 days before or 30 days after MM diagnosis) on survival was also estimated using a Cox regression model. All models were adjusted for age, sex, time of diagnosis, and previous fractures. Results A total of 14,008 patients were diagnosed with MM in the study period. A total of 4,141 (29.6%) patients developed a fracture including fractures that occurred within a year before MM diagnosis and thereafter. Hereof 2,893 (20.7%) patients developed a fracture after MM diagnosis. The risk of death was significantly increased for patients that developed a fracture after the time of MM diagnosis with a hazard ratio (HR) of 2.00 (95% confidence interval (CI) 1.91-2.10) for all fractures combined. The risk of death was significantly increased for patients that developed all subtypes of fractures after MM diagnosis except ankle fractures. The risk of death was significantly increased for patients that developed pathologic fractures (HR=2.17; 95% CI 2.03-2.32), vertebral fractures (HR=1.73; 95% CI 1.61-1.87), hip fractures (HR=1.99; 95% CI 1.82-2.18), femoral fractures (HR=2.62; 95% CI 2.32-2.98), humerus fractures (HR=2.57; 95% CI 2.32-2.86), forearm fractures (HR=1.24; 95% CI 1.05-1.46), and rib fractures (HR=1.52; 95% CI 1.31-1.77), but not for ankle fractures (HR 1.07; 95% CI 0.79-1.44). A total of 942 (6.7%) of all MM patients were diagnosed with a fracture within 30 days before or 30 days after MM diagnosis. The patients with a fracture at diagnosis were at a significantly increased risk of death compared to those without (HR 1.31; 95% CI 1.21-1.41; Figure) Conclusions Our large population-based study, including over 14,000 patients diagnosed with MM in Sweden in the years 1990-2013, showed that MM patients that developed a fracture after the time of diagnosis were at twofold increased risk of dying compared to MM patients without a fracture. Furthermore, MM patients with a fracture at diagnosis had a 30% higher risk of dying compared to patients without a fracture. Our results indicate that fractures in MM reflect a more advanced disease at diagnosis and stress the importance of managing MM bone disease in all MM patients. Figure. Figure.

217 Background: AYAs (15-39y at diagnosis) with cancer have not seen the survival improvement evidenced by younger and older age groups with similar diagnoses, leaving an AYA Gap. While treatment on pediatric protocols is associated with superior survival in 15-21y, impact of site of care on survival for vulnerable AYA subpopulations (race/ethnicity) between 22-39y at diagnosis remains unstudied. Methods: Utilizing a cohort of 10,602 AYAs newly diagnosed between 22-39y with lymphoma, leukemia, brain tumors, melanoma, thyroid and GU cancers, and reported to the Los Angeles County cancer registry between 1998 and 2008, we aimed to determine the impact of receiving care at NCI Comprehensive Cancer Centers (NCICCC) on overall survival for AYAs, and disparities in survival by race/ethnicity. We further aimed to understand the role of SES and insurance status in accessing care at NCICCC. Multivariable analyses included race/ethnicity, age at diagnosis, SES, insurance status, primary cancer diagnosis and diagnosis year in the model. Results: A total of 904 (9%) patients received treatment at the 3 NCICCC (City of Hope, Jonsson Cancer Center, and Norris Cancer Center) in LA County. Ten-year overall survival (10y OS) was significantly worse for patients treated at non-NCICCC (81%) when compared with those treated at NCICCC (83%, p=0.02). Also, 10y OS was worse for African Americans (AA) (68%) vs. non-Hispanic whites (86%, p<0.0001). Multivariable analysis adjusting for SES, insurance status, diagnosis and diagnosis year revealed that AA (HR=1.5, p=0.0001) were at an increased risk of death. Among patients treated at NCICCC, the difference in risk of death due to race (HR=0.9, p=0.84) was abrogated. However, among patients treated at non-NCICCC, these differences in outcome persisted (HR=1.48, p<0.0001). Independent of SES, insurance and tumor factors, AA (OR=0.44, p<0.001) were less likely to use NCICCC. Conclusions: Population-based data reveal that receipt of care at an NCICCC abrogates the inferior outcome observed among AA with cancer. AA are less likely to use NCICCC for treatment. Barriers to accessing care at NCICCC are currently being explored.

6537 Background: AYA (15-39y) have not seen survival improvement as in younger or older ages with similar cancer diagnoses, leaving an AYA Gap. Pediatric protocol use is associated with superior survival among 15-21y-olds, but impact of site of care for complex diseases with poor prognosis (such as CNSt) that require multidisciplinary, evidence-based care available at NCICCC, are unstudied. Methods: We constructed a cohort of 746 AYA with newly diagnosed CNSt, reported to the LA cancer registry from 1998-2008; 133 (18%) were treated at the 3 NCICCC in LA county. We examined clinical (WHO grade, diagnosis (dx) year, site of care) and demographic (age at dx, gender, SES, insurance, race/ethnicity) variables univariately; we included only those with p<0.1 in the final multivariable model (retaining WHO and NCICCC). Analysis was stratified by time from dx (≤2y, n=746; >2y, n=493) to examine impact of care at NCICCC among AYA with aggressive disease (resulting in death within 2y from dx) vs. those who survived 2y from dx – representing disease likely amenable to new strategies for control. Results: 5y overall survival (OS) was 59% and did not differ by site of care (p=0.2). Multivariable analysis restricted to the first 2y revealed an increased risk of death among those with high WHO grade (HR 4.7, p<.0001); public/no insurance (HR 1.7, p=0.0006); and African American/Asian (HR 2.1, p=0.0006) or Hispanic (HR 1.4, p=0.08) origin; site of care did not impact mortality. Among 2-y survivors, high WHO grade (HR 1.7, p=0.002) continued to be associated with increased risk of death. However, receipt of care at non-NCICCC site (HR 1.6, p=0.056) was also associated with increased risk of death. Examination of access to care at NCICCC revealed that after adjusting for WHO grade and gender, older age (22-39y (OR 0.3, p<0.0001), low SES (OR 0.6, p=0.04), and non-white ethnicity (OR 0.5, p=0.004), decreased likelihood of care at NCICCC. Conclusions: Population-based data reveal better OS in 2-y AYA survivors of CNSt receiving care at NCICCC. Older AYAs from low SES and non-white backgrounds are less likely to use NCICCC. AYA barriers to accessing NCICCC care are currently being explored.

Objective. Assessment of the impact of National Program «Health» on a rectal cancer (RC) tumor-specific survival in the Arkhangelsk region (AR), Russia over the period 2000–2017 by the data of Arkhangelsk Regional Cancer Registry (ARCR)Materials and methods. Anonymized data on all cases of RC (C19.0–C21.0) in the AR in 2000–2017 were extracted from the database of the ARCR. Over the study period, 4173 cases of the RC were selected. To assess the impact of the National Health Project in 2006 and All-national Dispensarization in 2013, the three time periods were chosen — 2000–2006, 2007–2012 and 2013–2017. Cancer-specific survival (CSS) was calculated. Separate influence of baseline factors on differences in CSS between periods was performed using Cox regression with consecutive input.Results. One- and five year CSS were 62,6% (95% confidence interval (CI) 60,03–65,05%%) and 27,8% (95% CI 25,4–30,2%) in 2000–2006, 65,1% (95% CI 62,5–67,5%) and 32% (95% CI 29,5–34,5%) in 2007–2012, 67,7% (95% CI 65,2–70,1%) and 37,4% (95% CI 33,7–41,1%) in 2013–2017, respectively.In univariate analysis the risk of death in the latest time periods was significantly lower: HR 0.86 (95% CI 0.79–0.95), p < 0.05 and 0.74 (95% CI 0.67–0.82), p<0.0001 for 2007–2012 and 2013–2017, respectively, comparing to 2000–2006. In a multivariate model only correction for treatment type has led to change of the coefficients between time periods: HR 0.94 (95% CI 0.86–1.03) and 0.84 (95% CI 0.75–0.93) for 2007–2012 and 2013–2017, respectively. The CSS was also independently influenced by stage, age at diagnosis, place of residence and type of treatment.Conclusion. Population-based five-year CSS of patients with RC increased by 8% during the analyzed period. Better CSS in the latest time period is associated rather with improvement of treatment than earlier detection of RC.

Abstract Background Data on the prevalence and impact of influenza–tuberculosis coinfection on clinical outcomes from high–HIV and –tuberculosis burden settings are limited. We explored the impact of influenza and tuberculosis coinfection on mortality among hospitalized adults with lower respiratory tract infection (LRTI). Methods We enrolled patients aged ≥15 years admitted with physician-diagnosed LRTI or suspected tuberculosis at 2 hospitals in South Africa from 2010 to 2016. Combined nasopharyngeal and oropharyngeal swabs were tested for influenza and 8 other respiratory viruses. Tuberculosis testing of sputum included smear microscopy, culture, and/or Xpert MTB/Rif. Results Among 6228 enrolled individuals, 4253 (68%) were tested for both influenza and tuberculosis. Of these, the detection rate was 6% (239/4253) for influenza, 26% (1092/4253) for tuberculosis, and 77% (3113/4053) for HIV. One percent (42/4253) tested positive for both influenza and tuberculosis. On multivariable analysis, among tuberculosis-positive patients, factors independently associated with death were age group ≥65 years compared with 15–24 years (adjusted odds ratio [aOR], 3.6; 95% confidence interval [CI], 1.2–11.0) and influenza coinfection (aOR, 2.3; 95% CI, 1.02–5.2). Among influenza-positive patients, laboratory-confirmed tuberculosis was associated with an increased risk of death (aOR, 4.5; 95% CI, 1.5–13.3). Coinfection with other respiratory viruses was not associated with increased mortality in patients positive for tuberculosis (OR, 0.7; 95% CI, 0.4–1.1) or influenza (OR, 1.6; 95% CI, 0.4–5.6). Conclusions Tuberculosis coinfection is associated with increased mortality in individuals with influenza, and influenza coinfection is associated with increased mortality in individuals with tuberculosis. These data may inform prioritization of influenza vaccines or antivirals for tuberculosis patients and inform tuberculosis testing guidelines for patients with influenza.

The Impact

4532 Background: Cisplatin-based NAC can prolong overall survival (OS) in patients (pts) with MIBC. Utilization of NAC has increased to about 20% of pts with MIBC over the last decade. We evaluated NAC utilization with and without SOC cisplatin-based combination regimens and oncologic outcomes using registry data. Methods: This is a population-based analysis of linked SEER-Medicare data (2004-2011). We identified 4534 pts with MIBC (cT2-4N0-1) undergoing radical cystectomy (RC). Based on pharmacy records data, pts were stratified into 3 groups: SOC, non-SOC, and immediate cystectomy (IC). We used descriptive statistics to compare groups, and multivariate logistic regression to define factors associated with receiving SOC NAC. Competing risk bladder cancer-specific mortality (BCSM) incidence curves were generated and KM analysis was used to assess OS from time of RC. The impact of NAC on OS was evaluated with Cox regression analysis. Results: 694 (15.3%) pts received NAC, increasing from 11% in 2004 to 24.8% in 2011, with 345 (50%) receiving non-SOC, e.g. gemcitabine/carboplatin (49.3%), gemcitabine alone (21.2%), carboplatin alone (14.8%), cisplatin alone (8.4%), and methotrexate/vinblastine/ adriamycin/carboplatin (0.8%). On logistic regression, increasing age (OR 0.91, 95%CI 0.88 – 0.94, p < 0.0001), Hispanic/Latin ethnicity (OR 0.49, 95%CI 0.22 – 1.10, p = 0.08), and ≥moderate renal dysfunction (OR 0.20, 95%CI 0.08 – 0.51, p < 0.001) were associated with lower odds of SOC NAC. Non-SOC NAC was associated with higher BCSM (competing risk) and lower OS (KM) vs. IC and SOC NAC. On multivariable analysis, non-SOC NAC was associated with higher risk of BCSM (HR 1.35, 95%CI 1.06 – 1.72, p = 0.01) and lower OS (HR 1.38, 95%CI 1.11 – 1.70, p = 0.003) vs. SOC NAC. Conclusions: About 50% of pts receiving NAC were not treated with SOC regimens. Non-SOC NAC was associated with higher bladder cancer death risk. This stresses the role of SOC NAC ideally in a multidisciplinary expert setting, as well as the need for timely RC and neoadjuvant clinical trials, including cisplatin-ineligible pts.
