Background. The purpose of this study was to evaluate the overall survival (OS) and associated characteristics for patients with Myxoid Liposarcoma (MLS) over time in The Netherlands. Methods. A population-based study was performed of patients with primary localized (n = 851) and metastatic (n = 50) MLS diagnosed in The Netherlands between 1989 and 2016, based on data from the National Cancer Registry. Results. The median age of the MLS patients was 49 years, and approximately two-thirds was located in the lower limb. An association was revealed between age and the risk of having a Round Cell (RC) tumor. OS rates for primary localized MLS were 93%, 83%, 78%, and 66% after 1, 3, 5, and 10 years, respectively. The median OS for patients with metastatic disease at diagnosis was 10 months. Increasing age (Hazard Ratio (HR) 1.05, p=0.00), a tumor size >5 cm (HR 2.18; p=0.00), and tumor location (trunk HR 1.29; p=0.09, upper limb HR 0.83; p=0.55, and “other” locations HR 2.73; p=0.00, as compared to lower limb) were independent prognostic factors for OS. The percentage of patients treated with radiotherapy (RT) increased over time, and preoperative RT gradually replaced postoperative RT. In contrast to patients with localized disease, significant improvement of OS was observed in patients with metastatic disease over time. Conclusions. In this large nationwide cohort, tumor size and tumor location were independent prognostic factors for OS. Furthermore, a higher probability of an RC tumor with increasing age was suggested. An increased use of RT over the years did not translate into improved OS for localized MLS.

End Results

Aim: To establish and validate a nomogram for the estimation of overall survival of patients with uterine leiomyosarcoma (uLMS). Methods: Information on patients diagnosed as uLMS was retrospectively retrieved from the Surveillance, Epidemiology, and End Results database. The patients were randomly assigned into the training and the validation cohorts. Univariate and multivariate analyses were used to determine the independent prognostic factors for building a nomogram for predicting overall survival. The predictive accuracy was evaluated based on the concordance indices and the calibration plots. Results: A nomogram that combined age, marital status, tumor size, Surveillance, Epidemiology, and End Result stage, surgery and radiation was established. The internal and external concordance indices were 0.748 and 0.745, respectively. The calibration plots approached 45 degrees. Conclusion: The nomogram might be an effective tool for predicting the survival of patients with uLMS.

184 Background: A recent study of the SEER database in the United States showed a 5-fold increase in neuroendocrine tumours (NETs) over the last 30 years. An increasing incidence has also been reported in Norway, Sweden, England, Holland, Italy and Japan, but interestingly not in Denmark and Switzerland. The objective of our study is to describe the incidence, anatomical distribution and survival of NETs in Ontario. Methods: A population based study was initiated using the Ontario Cancer Registry, cross-linked with the Registered Persons Database and the Canadian Institute of Health Information Discharge Abstract Database. All cases of NETs were identified in Ontario (> 13 million persons) from 1994 to 2009. Baseline demographic, clinical and outcomes data were abstracted to allow for an analysis of annual incidence rates, and overall survival. Results: A total of N = 5619 cases were identified. The incidence rate increased from 2.46/ 100,000 (95% CI, 2.13-2.83) in 1994 to 5.86/ 100,000 (95% CI, 5.40 – 6.35) in 2009. The median age was 62 with 50.5% female cases. When divided by site, bronchopulmonary NETs where the most common (22%), then jejunum/ileum (17%) and rectal (16%) NETs, while pancreatic NETs (pNETs) and gastric NETs were 10% and 5% respectively. The absolute increase in the study period was most pronounced for pNETs (6-fold), rectal (5-fold) and gastric (5-fold) NETs. Metastatic disease was documented in 45% of the cases; 20% at diagnosis and 25% during follow-up. The 5-and 10-year overall survival (OS) was 61% and 46% respectively, for the entire population. Site specific 5-year OS were: rectal (87.0%), small bowel (73.4%), gastric (67.4%), colon (64.3%) and pancreas (48.8%). 5-year OS was compared for patients with and without metastatic disease after diagnosis (69.0% vs 40.1%, p<0.0001). Conclusions: There appears to be a significant increase of reported cases of NETs in Ontario, Canada, particularly pNETs, rectum NETs and gastric NETs. This supports much of the population-based reports worldwide. Survival appears to vary significantly according to anatomical site and extent of disease. Further research is required to understand the impact of this cancer previously perceived to be rare but clearly increasing.

BackgroundFor oncologists and for patients, no site-specific clinical trial evidence has emerged for the use of concurrent chemotherapy with radiotherapy (ccrt) over radiotherapy (rt) alone for cancer of the hypopharynx (hpc) or for other human papilloma virus–negative head-and-neck cancers.Methods This retrospective population-based cohort study using administrative data compared treatments over time (1990–2000 vs. 2000–2010), treatment outcomes, and outcomes over time in 1333 cases of hpc diagnosed in Ontario between January 1990 and December 2010.Results The incidence of hpc is declining; the use of ccrt that began in 2001 is increasing; and the 3-year overall survival for all patients remains poor at 34.6%. No difference in overall survival was observed in a comparison of patients treated in the decade before ccrt and of patients treated in the decade during the uptake of ccrt.Conclusions The addition of ccrt to the armamentarium of treatment options for oncologists treating head-and neck patients did not improve outcomes for hpc at the population level.

Abstract BackgroundGlioblastoma (GBM) is a highly malignant brain tumor with poor survival and prognosis. Randomized trials have demonstrated that chemotherapy improves survival in patients with GBM. This study aims to examine the clinical characteristics that are potentially associated with the efficacy of chemotherapy and the risk factors of GBM.MethodsA total of 25,698 patients diagnosed with GBM were identified between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER). The clinical and demographic variables between groups were examined by Student's t-test and Pearson's chi-squared test. GBM-specific survival (GBMSS) and overall survival (OS) were evaluated using the Kaplan-Meier method with the log-rank test. Univariable and multivariable analyses were also performed using the Cox proportional hazard model to identify statistically significant prognostic factors.ResultsPatients who received chemotherapy had better overall survival (median OS 13 vs. 3 months, HR=1.9224, 95%CI 1.8571-1.9900, p<0.0001) and better GBMSS (median GBMSS of 12 vs. 3 months, HR=1.9379, 95%CI 1.8632-2.0156, p<0.0001) compared with patients who did not. Further subgroup analysis revealed that among patients who underwent chemotherapy, those who were younger, with the well-differentiated tumor, with a supratentorial tumor, received surgery or radiotherapy had both improved OS and GBMSS. Age, race, tumor grade, tumor location, tumor size, and treatments were identified as independent prognostic factors by multivariable analyses for patients with glioblastoma. ConclusionPatients with GBM who were younger (<65 years), with the well-differentiated tumor, underwent surgery or radiotherapy can benefit more from chemotherapeutic regimens. Age, race, tumor size, tumor location, tumor grade, surgery, radiotherapy, and chemotherapy were factors associated with the prognosis of patients with GBM.

Over Time

This retrospective population-based study examined the impact of age and comorbidity burden on multimodal management and survival from colorectal cancer (CRC). From 2000 to 2015, 1479 consecutive patients, who underwent surgical resection for CRC, were reviewed for age-adjusted Charlson comorbidity index (ACCI) including 19 well-defined weighted comorbidities. The impact of ACCI on multimodal management and survival was compared between low (score 0–2), intermediate (score 3) and high ACCI (score ≥ 4) groups. Changes in treatment from 2000 to 2015 were seen next to a major increase of laparoscopic surgery, increased use of adjuvant chemotherapy and an intensified treatment of metastatic disease. Patients with a high ACCI score were, by definition, older and had higher comorbidity. Major elective and emergency resections for colon carcinoma were evenly performed between the ACCI groups, as were laparoscopic and open resections. (Chemo)radiotherapy for rectal carcinoma was less frequently used, and a higher rate of local excisions, and consequently lower rate of major elective resections, was performed in the high ACCI group. Adjuvant chemotherapy and metastasectomy were less frequently used in the ACCI high group. Overall and cancer-specific survival from stage I-III CRC remained stable over time, but survival from stage IV improved. However, the 5-year overall survival from stage I–IV colon and rectal carcinoma was worse in the high ACCI group compared to the low ACCI group. Five-year cancer-specific and disease-free survival rates did not differ significantly by the ACCI. Cox proportional hazard analysis showed that high ACCI was an independent predictor of poor overall survival (p < 0.001). Our results show that despite improvements in multimodal management over time, old age and high comorbidity burden affect the use of adjuvant chemotherapy, preoperative (chemo)radiotherapy and management of metastatic disease, and worsen overall survival from CRC.
