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.

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]

254 Background: We investigated the effect of comorbidity, age, health insurance payer status, and race on the risk of nonadherence with National Comprehensive Cancer Network (NCCN) treatment guidelines for colorectal cancer (CRC) patients. In addition, the prognostic impact of NCCN treatment nonadherence on survival was assessed. Methods: Colon and rectal cancer patients who received primary treatment at Memorial University Medical Center in Savannah, GA from 2003 to 2010 were eligible for this study (final N = 679). Modified Poisson regression was used to obtain risk ratios for the outcome of nonadherence with NCCN treatment guidelines. Hazard ratios (HRs) for the relative risk of CRC-related death were obtained by Cox regression. Results: Guideline-adherent treatment was received by 82.5% of patients. Moderate/severe comorbidity, being uninsured, having rectal cancer, older age, and increasing tumor stage were associated with increased risks of receiving nonadherent treatment. Treatment nonadherence was associated with 4.5 times the risk of CRC-related death (HR, 4.53; 95% CI, 2.56-8.00) in the first year following diagnosis and 2.0 times the risk of death (HR, 1.97; 95% CI, 1.20-3.25) in years 2 to 5. The detrimental effect of nonadherence was demonstrated across all levels of comorbidity and age. Conclusions: Although there are medically justifiable reasons to deviate from NCCN treatment guidelines in CRC patients, patients who received nonadherent treatment had much higher risks of CRC-related death, especially in the first year following diagnosis. This study’s results highlight the importance of cancer health services research to drive quality improvement efforts in cancer care for CRC patients. [Table: see text]

Background: Preclinical models have suggested a role for sex hormones in the development of glioblastoma multiforme (GBM). However, the impact of gender on the survival time of patients with GBM has not been fully understood. The objective of the present study was to clarify the association between gender and survival of patients with GBM by analyzing population-based data. Methods: We searched the Surveillance, Epidemiology, and End-Results database who were diagnosed with GBM between 2000 and 2008 and were treated with surgery. Five-year cancer specific survival data were obtained. Kaplan–Meier methods and multivariable Cox regression models were used to analyze long-term survival outcomes and risk factors. Results: A total of 6586 patients were identified; 61.5% were men and 38.5% were women. The 5-year cancer-specific survival (CSS) rates in the male and female groups were 6.8% and 8.3%, respectively (P=0.002 by univariate and P<0.001 by multivariate analysis). A stratified analysis showed that male patients always had the lowest CSS rate across localized cancer stage and different age subgroups. Conclusions: Gender has prognostic value for determining GBM risk. The role of sex hormones in the development of GBM warrants further investigation.

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.

Aim The role of surgery in the treatment of metastatic pancreatic neuroendocrine tumors (PNETs) was controversial. The objectives of this study were to illustrate the impact of surgery in improving the prognosis of patients with metastatic PNETs and build nomograms to predict overall survival (OS) and cancer-specific survival (CSS) based on a large population-based cohort. Methods Patients diagnosed with metastatic PNETs between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database were retrospectively collected. Nomograms for estimating OS and CSS were established based on Cox regression model and Fine and Grey’s model. The precision of the nomograms was evaluated and compared using concordance index (C-index) and the area under receiver operating characteristic (ROC) curve (AUC). Results The study cohort included 1966 patients with metastatic PNETs. It was shown that the surgery provided survival benefit for all groups of patients with metastatic PNETs. In the whole study cohort, 1-, 2- and 3-year OS and CSS were 51.5, 37.1 and 29.4% and 53.0, 38.9 and 31.1%, respectively. The established nomograms were well calibrated, and had good discriminative ability, with C-indexes of 0.773 for OS prediction and 0.774 for CSS prediction. Conclusions Patients with metastatic PNETs could benefit from surgery when the surgery tolerance was acceptable. The established nomograms could stratify patients who were categorized as tumor-node-metastasis (TNM) IV stage into groups with diverse prognoses, showing better discrimination and calibration of the established nomograms, compared with 8th TNM stage system in predicting OS and CSS for patients with metastatic PNETs.

e16122 Background: Docetaxel is the standard first-line treatment for patients (pts) with metastatic HRPC. Taxanes are a well known cause of nail toxicity but docetaxel-related nail toxicity is rarely explored. Methods: Eligible HRPC pts included in the current analysis were from a phase II, multicentre, case-control study (Scotte F et al, J Clin Oncol 2005). Pts were treated with docetaxel 75 mg/m2 every 3 weeks and oral prednisone 10 mg daily. Nail toxicity was graded according to NCI CTC version 2 (0: absence of toxicity; 1: minor changes; 2: onycholisis). The endpoint of interest was the impact of nail toxicity on overall survival (OS) using Cox regression analysis as the main statistical method. OS was the time from the start of chemotherapy to death or last follow-up. Results: Data from 23 HRPC pts treated in two French centres were analyzed. The median age was 68 years, 91% of pts had bone metastases, 84% had a single metastatic site, 49% had a Gleason score of ≥ 8 and 91% had an ECOG performance status (PS) of 0 or 1. Median OS was 16.7 months [95% confidence interval (CI), 5.7–27.6 months], all pts died. There were differences in OS between nail toxicity categories (see Table). Median OS was 10.6 months (95% CI, 9.5–11.7) and 22.7 months (95% CI, 15.1–30.3) for pts without and with nail changes, respectively. Nail changes severity was significantly related to OS: hazard ratio (HR)=0.50 (95% CI, 0.28–0.92), P=0.027 (univariate analysis). The multivariate analysis adjusted by ECOG PS (the second covariate associated with prognosis) showed a 63% reduction in the risk of death for pts with nail toxicities: HR=0.29 (95% CI, 0.09–0.82), P=0.049. Conclusions: Our results suggest that pts with docetaxel-related nail toxicity have a better OS than those with no nail toxicity. This demonstrates that nail changes in HRPC pts treated with docetaxel are predictive of OS; these findings should be validated in a large cohort of pts.

807 Background: The incidence of CRC increases significantly with age. Despite the benefits associated with adjuvant therapy, older pts are frequently treated less aggressively due to perceived poor tolerance to treatment, comorbidity, or limited life expectancy. We aim to examine the impact of chronological age on use of perioperative therapies in a contemporary cohort of pts and determine differences in outcomes based on age. Methods: Adult pts who underwent surgical resection for stage II or III CRC in Alberta, Canada from 2004 to 2015 were analyzed. Pts were stratified based on pre-specified age sub-groups. Overall survival (OS) and cancer specific survival (CSS) were assessed using the Kaplan-Meier method and compared with the log-rank test. A Cox proportional hazards model was constructed to evaluate the impact of age on outcomes. Results: We identified 8,538 pts of whom 56% were men, 53% had stage III disease, and 26% had rectal cancer. Older pts were more likely diagnosed with right-sided tumors, earlier stage, and higher Charlson comorbidity index (CCI) (all p <.01). Chemotherapy (CT) use decreased significantly with advancing age, even in recent years (Table). Older rectal cancer pts were also less likely to receive radiation (p <.01). Elderly age was the strongest predictor for not using CT, after adjusting for sex, stage, tumor location, and CCI. On multivariate Cox regression, older age was associated with inferior OS and CSS, but CT improved outcomes. Conclusions: Despite evidence of benefit and prior studies recommending treatment of elderly, the current cohort of older pts with resected stage II and III CRC continue to undergo perioperative therapy less commonly than their younger counterparts.

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 We reported previously that rectal cancer patients given curative-intent chemotherapy, radiation, and surgery for non-metastatic disease had enhanced risk of metastatic progression and death if circulating levels of 25-hydroxyvitamin D [25(OH) D] were low. Here we investigated whether the association between the vitamin D status and prognosis pertains to the general, unselected population of rectal cancer patients. Methods Serum 25(OH) D at the time of diagnosis was assessed in 129 patients, enrolled 2013–2017 and representing the entire range of rectal cancer stages, and analyzed with respect to season, sex, systemic inflammation, and survival. Results In the population-based cohort residing at latitude 60°N, 25(OH) D varied according to season in men only, who were overrepresented among the vitamin D-deficient (< 50 nmol/L) patients. Consistent with our previous findings, the individuals presenting with T4 disease had significantly reduced 25(OH) D levels. Low vitamin D was associated with systemic inflammation, albeit with distinct modes of presentation. While men with low vitamin D showed circulating markers typical for the systemic inflammatory response (e.g., elevated erythrocyte sedimentation rate), the corresponding female patients had elevated serum levels of interleukin-6 and the chemokine (C-X-C motif) ligand 7. Despite disparities in vitamin D status and the potential effects on disease attributes, significantly shortened cancer-specific survival was observed in vitamin D-deficient patients irrespective of sex. Conclusion This unselected rectal cancer cohort confirmed the interconnection of low vitamin D, more advanced disease presentation, and poor survival, and further suggested it may be conditional on disparate modes of adverse systemic inflammation in men and women.
