Background Pancreatic cancer (PC) is one of the most lethal types of cancer and surgery remains the most optimal treatment modality for patients with resectable tumors. The objective of this study is to examine and compare the trends in survival rate among PC patients based on treatment modality.Methods This population-based retrospective analysis included all patients with known stage for PC in Ontario, Canada between 2007 and 2015. Flexible parametric models were used to conduct survival analysis. Survival rates were calculated based on treatment modality, while adjusting for patient and tumor specific covariates.Results In total, 6437 patients were included in this study. More than half of the patients aged 80 and over received no curative treatment. The proportion of patients receiving chemoradiation decreased over time. The 1-, 2- and 5-year survival rates increased 30-40% for stage I disease and less than 15% for stage II over the study period. Noticeable increases in 1-, 2, and 5-year survival rates were observed for patients underwent for distal pancreatectomy and Whipple procedures. There were no changes in survival for stage III and IV disease from 2007 to 2015.Conclusions A majority of cases for PC continue to be diagnosed in late stage, with poor short-term and long-term prognosis. The survival for stage I tumors and surgical modalities increased over time without any evidence of changes in stage distribution. We speculate that improvements in chemotherapy modalities and adoption of quality standards for surgical resection could be attributed for the positive trends in survival.

7538 Background: Clinical trials demonstrating improved survival with AC for stages I-III NSCLC are limited in their applicability to broader populations. We sought to describe the pattern of AC use and its correlation with survival in the population-based VA system. Methods: We conducted a retrospective analysis of pts with stages I-III NSCLC in the VA Central Cancer Registry. Descriptive statistics were used to examine patterns of AC use over an 8 yr period and to obtain survival rates associated with use of AC. Chi-square was used to compare distributions. Results: Among 28,173 pts with stages I-III NSCLC in 2001-2008, 10,043 had surgical resection. The proportion receiving AC was 9% (stage I), 34% (II), and 40% (III). Receipt of AC increased for each stage, with the greatest increase observed in stage II (2001-03: 12%; 2004-05: 41%; 2006-08: 50%). About 90% received a platinum agent; among these carboplatin was most common (77%) but by 2008 43% received cisplatin. For stages II and III in 2001-2003, the 3-year survival rate was similar irrespective of AC use. In latter time periods, survival rates were significantly higher for stage II AC pts (2004-2005: 53 vs 43%, p=0.03; 2006-2008: 58 vs 46%, p=0.001). Stage III AC pt diagnosed in 2006-2008 had a higher 3-yr survival (52 vs 36%, p<0.001). For all stages and years combined, use of cisplatin yielded a better 3-yr survival rate compared to carboplatin (62% vs 55%; p=0.01). 3-yr survival for stage I, II, and III, regardless of AC, increased over time (stage I: 60, 64, and 69%; stage II: 44, 47, 52%; stage III: 33, 40, and 44%). The fraction of lung cancer pts diagnosed at each stage during the 3 time periods was not significantly different. Conclusions: This retrospective study suggests a significant increase in use of AC for NSCLC in the VA, though half of surgically treated pts with stage II and III did not receive AC in 2006-2008. By univariate analysis, AC use is associated with a significantly better 3-yr survival for resected stage II and III NSCLC and the stage-specific 3-year survival for all pts improved over time in association with increasing use of AC. Cisplatin is associated with better survival compared to carboplatin. Multivariate analysis is planned.

6503 Background: Examined lymph node (ELN) number is an important quality metric in cancer care. This large international cohort study aimed to investigate the associations of ELN number with accurate staging and long-term survival in pancreatic cancer (PaC) and to robustly determine the minimal and optimal ELN thresholds. Methods: Population-based data on patients with stage I-II PaC resected in 2003-2015 from the US Surveillance, Epidemiology, and End Results (SEER)-18 Program and Netherlands National Cancer Registry (NCR) were analyzed. Associations of ELN number with stage migration and survival were evaluated using multivariable-adjusted logistic and Cox regression models, respectively. The series of odds ratios (ORs) for stage migration and hazard ratios (HRs) for survival with more ELNs were fitted using a LOWESS smoother, and structural breakpoints were determined by Chow test. Results: Overall 18,303 patients were analyzed. With increasing ELN number, both cohorts exhibited significant proportional increases from node-negative to node-positive disease (ORSEER-18= 1.05, 95% CI = 1.04-1.05; ORNCR= 1.10, 95% CI = 1.08-1.12) and serial improvements in survival (HRSEER-18= 0.98, 95% CI = 0.98-0.99; HRNCR= 0.98, 95% CI = 0.97-0.99) per additional ELN after controlling for confounders. Associations for stage migration and survival remained significant in most stratifications by patient, tumor, and treatment factors. Cut-point analyses suggested a minimal threshold ELN number of 12 and an optimal number of 19, which were validated both internally in the derivative US cohort and externally in the Dutch cohort with the ability to well discriminate different probabilities of both survival and stage migration. Conclusions: In stage I-II PaC, more ELNs are associated with more precise nodal staging, which might largely explain the survival association. Our results robustly conclude 12 ELNs as the minimal and suggest 19 ELNs as the optimal cut-points, for evaluating quality of lymph node examination and possibly for stratifying postoperative prognosis. Our findings provide important references for defining population-based quality metrics in PaC care.

Abstract Background Recent studies have shown that mixed predominantly differentiated-type (MD) early gastric cancer (EGC) might have more malignant potential than pure differentiated-type (PD) EGC. However, no study has analyzed all differentiated-type EGC cases treated endoscopically and surgically. This study aimed to compare the differences in clinicopathological features and long-term prognosis between MD- and PD-EGC. Methods We evaluated all patients with differentiated-type EGCs who were treated endoscopically and surgically in our hospital between January 2010 and October 2014. The clinicopathological features and long-term prognosis of MD-EGC were compared with those of PD-EGC. Results A total of 459 patients with 459 lesions were evaluated in this study; of them, 409 (89.1%) and 50 (10.9%) were classified into the PD and MD groups, respectively. Submucosal invasion was found in 96 (23.5%) patients of the PD group and in 33 (66.0%) patients of the MD group (p < 0.01). The rates of positive lymphatic and vascular invasion and ulceration were significantly higher in the MD group than in the PD group (p < 0.01). The proportion of patients with lymph node metastasis was also significantly higher in the MD group than in the PD group (5 (10%) vs 6 (1.5%), p < 0.01). The 5-year overall and EGC-specific survival rates in the PD group were 88.3 and 99.5%, respectively, while they were 94.0 and 98.0% in the MD group, respectively. Conclusions MD-EGC has more malignant potential than PD-EGC. However, the long-term prognosis of MD-EGC is good and is not significantly different from that of PD-EGC when treated appropriately.

Olfactory neuroblastoma (ONB) is a rare neuroepithelial-derived malignancy that usually presents in the nasal cavity. The rarity of ONB has led to conflicting reports regarding associations of patient age and ONB survival and outcome. Moreover, long-term outcomes of chemotherapy and other treatment modalities are speculated. Here, we aimed to compare survival outcomes across age groups through time and determine associations between treatment modality and survival. In this retrospective population-based study, we analyzed the SEER 2000–2016 Database for patients with ONB tumors. Using Kaplan–Meier survival analysis, a significant effect of age and cancer-specific survival (CSS) was observed; geriatric ONB patients had the lowest CSS overall. Generalized linear models and survival analyses demonstrated that CSS of the pediatric patient population was similar to the geriatric group through 100 months but plateaued thereafter and was the highest of all age groups. Radiation and surgery were associated with increased CSS, while chemotherapy was associated with decreased CSS. GLM results showed that tumor grade, stage and lymph node involvement had no CSS associations with age or treatment modality. Our results provide insight for future investigations of long-term outcomes associated with ONB patient age and treatment modality, and we conclude that survival statistics of ONB patients should be analyzed in terms of trends through time rather than fixed in time.

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.

Aim Pancreatic cancer is one of the deadliest malignant neoplasms. As with many malignant neoplasms, survival rates depend on the histopathological type of cancer, its stage, tumor size, and treatment. In this study, we aimed to classify pancreatic cancer according to clinicopathological features and histological subtypes. Material and method The data of all adult patients diagnosed and treated for pancreatic neoplasm in our clinic were collected retrospectively from the hospital's computerized database and medical files. Patients were categorized according to their clinicopathological features. Chi-square test and Fisher's exact test were used for between-group comparisons, and t-test was used for independent samples for quantitative data. Data were expressed as mean ± SD for continuous variables and numbers and percentages for categorical variables. A value of p<0.05 was considered significant. Results The mean age of the patients was 60.5 years, 70.8% were male. There were five types of tumors defined histopathologically, and the most common diagnosis was adenocarcinoma (76.9%). The most common localization of the tumor was head and neck (44.4%). Whipple surgery was performed predominantly in 69.2% of patients, and distal pancreatectomy in 29.0%. Postoperative complications were observed in more than one third (34%) of the patients. The main complications were pancreatic cyst (16.3%). In the survival analysis performed with the Kaplan-Meier test, median survival of 30.5 months, and overall survival (OS) at 1.2 and 5 years were 67.8%, 40.5%, and 16.6%, respectively. Discussion However, survival analysis results were optimistic compared to population-based studies as all patients had resectable tumors.
