Abstract Background This study aims to assess breast cancer survival rates after one decade of mammography in a large urban area of Brazil. Methods It is a population-based retrospective cohort of women with breast cancer in Campinas, São Paulo, from 2010 to 2014. Age, vital status and stage were accessed through the cancer and mortality registry, and patients records. Statistics used Kaplan-Meier, log-rank and Cox's regression. Results Out of the 2,715 cases, 665 deaths (24.5%) were confirmed until early 2020. The mean age at diagnosis was 58.6 years. Women 50-69 years were 48.0%, and stage I the most frequent (25.0%). The overall mean survival was 8.4 years (8.2-8.5). The 5-year survival (5yOS) for overall, 40-49, 50-59, 60-69, 70-79 years was respectively 80.5%, 87.7%, 83.7%, 83.8% and 75.5%. The 5yOS for stages 0, I, II, III and IV was 95.2%, 92.6%, 89.4%, 71.1% and 47.1%. There was no significant difference in survival in stage I or II (p=0.058). Compared to women 50-59 years, death's risk was 2.3 times higher for women 70-79 years and 26% lower for women 40-49 years. Concerning stage I, the risk of death was 1.5, 4.1 and 8.6 times higher, and 34% lower, respectively, for stage II, III, IV and 0. Conclusions In Brazil, breast cancers are currently diagnosed in the early stages, although advanced cases persist. Survival rates may reflect improvements in screening, early detection and treatment. The results can reflect the current status of other regions or countries with similar health care conditions.

Background. Population-based EUROCARE-5 studies demonstrated that childhood cancer survival rates in Lithuania were 10–20% lower than the European mean. We aimed to analyse the change in the outcome of treatment of paediatric malignancies in Lithuania over 30 years. Methods. A single-centre retrospective analysis of children below 18 years of age treated for cancer at Vilnius University Hospital Santaros Klinikos between 1982 and 2011 was carried out. The minimal requirement of 5-year follow-up after diagnosis was specified for survival estimation. The vital status was assessed using data from the population-based Lithuanian Cancer Registry. To evaluate changes over time, the entire cohort was split into three groups according to the time of diagnosis: 1982–1991, 1992–2001, and 2002–2011. Results. A total of 1268 children met the inclusion criteria. The shortest median follow-up was 8.9 (IQR 6.4–11.5) years for patients treated in the third decade. The 5-year overall survival of the entire cohort increased from 37.3% (95% CI 30.2–44.3) in 1982–1991 to 70.7% (95% CI 66.4–74.1) in 2002–2011 (p < 0.0001). The same trend was evident when calculated separately for leukaemia (p < 0.0001), lymphoma (p < 0.0005), and solid tumours (p < 0.004). The percentage of cure rose from zero in the early years of the period analysed to 80% in 2010 and 2011. The improvement in the treatment outcome was attributable to the reduction of treatment-related mortality from 45.8% in 1982–1991 to 12.4% in 2002–2011 and disease recurrence from 30.4% to 19.6% for the same periods, respectively. Conclusions. Significant progress in the cure rate of children treated for cancer at our institution was observed over 30 years. Collaborative national and international clinical and research efforts are crucial to ensure further advances in care and cure.

17008 Background: Based on population-based studies, some investigators have posited that patients undergoing more extensive lymphadenectomy as part of their resection for stomach cancer had improved late survival rates. Such findings have prompted calls for the use of total lymph node counts as a quality indicator for hospitals. However, apparent relationships between number of lymph nodes resected and survival may be confounded by patient selection bias and provider factors. It is not clear that hospitals with higher lymph node counts have better outcomes than other hospitals. The purpose of this study is to examine relationships between total lymph node counts and survival for stomach cancer. Methods: Using the national Surveillance Epidemiology and End Results (SEER)-Medicare linked database (1992–2002), we first identified all patients undergoing major resections for gastric cancer (n=3,049). Hospitals at which the procedures were performed were categorized into 3 groups (terciles) according to the median number of nodes examined. We then assessed 5-year survival rates for each hospital group, adjusting for potentially confounding patient and hospital characteristics. Results: Hospitals with the highest median lymph node counts had slightly higher 5-year survival rates than those with the lowest node counts (31% vs. 28%; unadjusted HR for mortality 0.90, 95% CI 0.81–1.00). Hospitals with higher lymph node counts tended to treat lower risk patients and had lower procedure volumes. Adjusting for these confounding patient and provider characteristics further weakened the apparent relationship between survival and lymph node counts by hospital (adjusted HR, high vs. low hospital tercile, 0.96; 95% CI 0.85–1.09). Conclusions: Apparent relationships between total lymph node counts by hospital and 5-year survival rates after resection for stomach cancer are relatively weak and explained in large part by confounding patient and provider factors. Stronger evidence should be required before moving forward with this metric as a hospital quality indicator. No significant financial relationships to disclose.

3576 Background: The patterns of capecitabine use as an alternative form of fluoropyrimidine to infusional 5-FU in the non-operative management of anal cancer in the real world are poorly described. Our objectives were to determine the frequency of capecitabine use, compare the observed outcomes between oral and intravenous fluoropyrimidines, and examine for variations in treatment-related adverse events between the two agents. Methods: All anal cancer patients who received either capecitabine or infusional 5-FU as part of their chemoradiation treatment from 2004 to 2013 at any 1 of 6 cancer centers in British Columbia were included. Chi-square and Wilcoxon-Mann tests were used to assess for associations between treatment groups and clinical characteristics and outcomes. Results: A total of 486 patients were identified: median age was 59 (IQR 53-67) years, 175 (36%) were men, 418 (86%) had ECOG 0/1, and 30 (6%) were HIV positive. Median total radiation dose was 54 cGy (IQR 50-54) and 47 (10%) underwent a colostomy prior to chemoradiation. Baseline characteristics were balanced between the two groups with respect to age, gender, ECOG, and HIV status (all p > 0.05). Prior to 2010, only 5-FU was utilized. From 2010 to 2013, 155 and 82 patients (65% vs 35%) received capecitabine vs 5-FU, respectively. Overall (68% vs 67%, p = 0.831) and disease-free survival rates (59% vs 59%, p = 0.926) at 3 years were similar in the capecitabine vs 5-FU groups. Rates of subsequent abdomino-perineal resection were also similar (10% vs 14%, p = 0.164). Patients who received 5-FU were more likely to report adverse effects (76% vs 57%, p < 0.01). The capecitabine group had a lower incidence of stomatitis (7% vs 43%, p < 0.01) whereas the 5-FU cohort reported less frequent hand-foot syndrome (1% vs 7%, p < 0.01). The rates of myelosuppression, nausea/vomiting, diarrhea, and rash were similar between the two groups (all p > 0.05). Conclusions: This represents one of the largest population-based studies to demonstrate a preference for capecitabine in place of 5-FU in the management of anal cancer. Survival outcomes were similar between the two treatment groups, but capecitabine may be better tolerated in the real world.

Abstract Background Brain tumours represent an important cause of cancer-related death in adolescents and young adults. Most are diagnosed in low-income and middle-income countries. We aimed to conduct the first systematic review of time trends and geographical variation in survival in this age group. Methods We included observational studies describing population-based survival from astrocytic tumours in patients aged 15-39 years. We queried six electronic databases from database inception to 30 September 2018. This review is registered with PROSPERO, number CRD42018111981. Results Among 5,245 retrieved records, 20 studies fulfilled the inclusion criteria. Only one study was partly conducted in middle-income countries. Five-year survival from astrocytoma (broad morphology group) varied between 48% and 71% (1973-2004), without clear trends or geographic differences. Adolescents with astrocytoma had better outcomes than young adults, but survival values were similar when non-malignant tumours were excluded. During 2002-2007, five-year survival for WHO grade I-II tumours was in the range 75-93% in England, Germany, and the US, but lower in South-Eastern Europe (59%). Five-year survival for anaplastic astrocytoma varied between 40% and 55% (2002-2007). Five-year survival from glioblastoma was in the range 15-23% (1991-2009). Conclusions Survival from astrocytic tumours remained somewhat steady over time, with little change between 1973 and 2009. Survival disparities were difficult to examine, because nearly all the studies were conducted in affluent countries. Studies often adopted the International Classification of Childhood Cancer, which, however, did not allow to accurately describe variation in survival. Larger studies are warranted, including under-represented populations and providing more recent survival estimates. Keywords Population-based survival, brain tumours, adolescents, young adults, time trends.

Abstract Background Data from population-based cancer registries are often used to compare cancer survival between countries or regions. The ICBP SURVMARK-2 study is an international partnership aiming to quantify and explore the reasons behind survival differences across high-income countries. However, the magnitude and relevance of differences in cancer survival between countries have been questioned, as it is argued that observed survival variations may be explained, at least in part, by differences in cancer registration practice, completeness and the availability and quality of the respective data sources. Methods As part of the ICBP SURVMARK-2 study, we used a simulation approach to better understand how differences in completeness, the characteristics of those missed and inclusion of cases found from death certificates can impact on cancer survival estimates. Results Bias in 1- and 5-year net survival estimates for 216 simulated scenarios is presented. Out of the investigated factors, the proportion of cases not registered through sources other than death certificates, had the largest impact on survival estimates. Conclusion Our results show that the differences in registration practice between participating countries could in our most extreme scenarios explain only a part of the largest observed differences in cancer survival.

680 Background: Capecitabine is used as an alternative fluoropyrimidine to infusional 5-FU in the non-operative management of anal cancer due to its ease of administration. However, its patterns of use and long-term outcomes in the real world are poorly described. Our objectives were to determine the frequency of capecitabine use, compare the difference in outcomes, and examine the difference in treatment-related adverse events between oral and intravenous fluoropyrimidines. Methods: All anal cancer patients who received either capecitabine or infusional 5-FU as part of their curative intent chemoradiotherapy from 2010 to 2013 at any 1 of 6 comprehensive cancer centers in British Columbia were included. Chi-square and Wilcoxon-Mann tests were used to assess for associations between treatment groups and clinical characteristics and outcomes. Results: A total of 237 patients were identified; median age was 59 (IQR 53-67) years, 71 (30%) were men, 202 (85%) had ECOG 0/1, and 12 (5%) were HIV positive. Median total radiation dose was 54 cGy (IQR 50.4-54.0) and 21 (9%) underwent a colostomy prior to chemoradiation. Baseline characteristics were balanced between the two groups with respect to age, gender, ECOG, and HIV status (all p > 0.05). Overall, 155 patients (65%) received capecitabine. Comparing patients who received capecitabine vs 5-FU, overall (69% vs 74%, p = 0.388) and disease-free survival rates (68% vs 71%, p = 0.637) at 5 years from diagnosis were similar between treatment groups. There were no differences with respect to rates of subsequent colostomy (16% vs 23%, p = 0.185) and abdominoperineal resection (11% vs 12%, p = 0.777). However, patients who received capecitabine were less likely to report adverse effects (51% vs 26%, p < 0.001) than those who underwent 5-FU. The capecitabine group had a lower incidence of stomatitis (6% vs 40%, p < 0.001) whereas the 5-FU cohort reported less frequent hand-foot syndrome (1% vs 8%, p = 0.036). Conclusions: This population-based study demonstrates a preference for capecitabine use in place of 5-FU in the curative management of anal cancer. Survival outcomes are similar between the two treatment groups, but capecitabine may be better tolerated.
