Background. Standard therapy for localized soft tissue sarcoma (STS) is wide, limb-sparing resection. For intermediate- or high-grade tumors, (neo)adjuvant therapies are frequently added to the treatment plan. In this study, data from a Dutch nationwide database are used to (1) assess whether perioperative management of STS follows ESMO guidelines, (2) characterize prognostic factors for overall survival (OS), and (3) assess the association between perioperative treatment and survival. Methods. All intermediate- or high-grade, localized STS cases, who have undergone surgery and diagnosed between 2000 and 2017, were identified in the Netherlands Cancer Registry (NCR) database. Variables with demographic, treatment, and survival data were obtained. Survival curves were estimated by Kaplan–Meier’s method, and the effect of prognostic factors on OS was assessed in a multivariable Cox regression analysis. Results. A total of 4957 patients were identified. There were slightly more males (54.7%). Median age at diagnosis was 64 years, and 53.6% of the tumors were located in the extremities. Radiotherapy (RT) was administered to 2481 (50.1%) patients, and 252 (5.1%) patients were treated with perioperative systemic chemotherapy. The total use of perioperative RT did not significantly change in the last 20 years, but the timing followed clinical guidelines: preoperative RT increased significantly (2000–2008: 3.7%, 2009–2017: 22.3%; p < 0.001 ), whereas the use of postoperative RT diminished (2000–2008: 45.9%, 2009–2017: 26.1%; p < 0.001 ). The use of perioperative chemotherapy slightly decreased (2000–2008: 5.9%, 2009–2017: 4.4%; p = 0.015). 5-year OS was 59.6% (95% CI: 58.2–61.0). Sex, age, year of diagnosis, tumor location, tumor size, histological grade, depth, histological subtype, surgical margins, and the use of perioperative RT were identified as independent predictors for OS. Conclusion. Preoperative RT is gradually replacing postoperative RT for localized STS in the Netherlands. The use of perioperative chemotherapy is rare and has slightly decreased in recent years. Identified baseline characteristics and treatment factors predicting OS may aid in future treatment decisions.

AbstractThe difference in incidence of oral cavity cancer (OCC) between Taiwan and the Netherlands is striking. Different risk factors and treatment expertise may result in survival differences between the two countries. However due to regulatory restrictions, patient-level analyses of combined data from the Netherlands and Taiwan are infeasible. We implemented a software infrastructure for federated analyses on data from multiple organisations. We included 41,633‬ patients with single-tumour OCC between 2004 and 2016, undergoing surgery, from the Taiwan Cancer Registry and Netherlands Cancer Registry. Federated Cox Proportional Hazard was used to analyse associations between patient and tumour characteristics, country, treatment and hospital volume with survival. Five factors showed differential effects on survival of OCC patients in the Netherlands and Taiwan: age at diagnosis, stage, grade, treatment and hospital volume. The risk of death for OCC patients younger than 60 years, with advanced stage, higher grade or receiving adjuvant therapy after surgery was lower in the Netherlands than in Taiwan; but patients older than 70 years, with early stage, lower grade and receiving surgery alone in the Netherlands were at higher risk of death than those in Taiwan. The mortality risk of OCC in Taiwanese patients treated in hospitals with higher hospital volume (≥ 50 surgeries per year) was lower than in Dutch patients. We conducted analyses without exchanging patient-level information, overcoming barriers for sharing privacy sensitive information. The outcomes of patients treated in the Netherlands and Taiwan were slightly different after controlling for other prognostic factors.

PURPOSE: The rarity and heterogeneity of pediatric nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) has precluded meaningful analysis of prognostic factors associated with surgically resected disease. To define a population of patients at high risk of treatment failure who might benefit from adjuvant therapies, we evaluated the relationship between various clinicopathologic factors and clinical outcome of children and adolescents with resected NRSTS over a 27-year period at our institution. PATIENTS AND METHODS: We analyzed the records of 121 consecutive patients with NRSTS who underwent surgical resection between August 1969 and December 1996. Demographic data, tumor characteristics, treatment, and outcomes were recorded. Univariate and multivariate analyses of prognostic factors for survival, event-free survival (EFS), and local and distant recurrence were performed. RESULTS: At a median follow-up of 9.2 years, 5-year survival and EFS rates for the entire cohort were 89% ± 3% and 77% ± 4%, respectively. In univariate models, positive surgical margins (P = .004), tumor size ≥ 5 cm (P < .001), invasiveness (P = .002), high grade (P = .028), and intra-abdominal primary tumor site (P = .055) adversely affected EFS. All of these factors except invasiveness remained prognostic of EFS and survival in multivariate models. Positive surgical margins (P = .003), intra-abdominal primary tumor site (P = .028), and the omission of radiation therapy (P = .043) predicted local recurrence, whereas tumor size ≥ 5 cm (P < .001), invasiveness (P < .001), and high grade (P = .004) predicted distant recurrence. CONCLUSION: In this largest single-institution analysis of pediatric patients with surgically resected NRSTS, we identified clinicopathologic features predictive of poor outcome. These variables should be prospectively evaluated as risk-adapted therapies are developed.

Abstract Background: Adrenocortical carcinoma (ACC) is a rare disease with often poor prognosis. Previous research has shown that surgery in a Dutch Adrenal Network (DAN) center increases the chance of survival. We aim to explore the determinants and survival of patients with ACC recently treated in the Netherlands both within and outside DAN centers. Methods: We analyzed retrospectively collected data from 172 adult patients with newly diagnosed ACC and 97 patients with recurrence or new metastases, registered between 2014 and 2019 in the Netherlands Cancer Registry. Differences in survival were analyzed with cox-regression analysis. Results: More than half of the new cases presented with advance disease (25.7% stage III, 34.6% stage IV) and the median survival was 29 months. The majority of treatments occurred within a DAN center (87.2% of surgery, compared to 56.4% between 1999 and 2009; and 94.5% of medical treatment). There were no differences in patient characteristics between the centers apart from a relatively high number of patients with stage IV disease outside DAN centers (47.2% vs. 28.7%). Adrenal resection and mitotane therapy both resulted in a significant survival benefit (resection HR 0.29, CI95%[0.17–0.49]; mitotane HR 0.61, CI95%[0.37–0.99], corrected for stage). Still, a remarkable proportion of patients with advanced disease received no mitotane treatment (39.8%). Due to the small number of patients treated outside DAN centers, survival benefits could not be tested. Conclusions: Centralization of ACC care in the Netherlands has improved since the previous report, but a further improvement in centralization of surgery can be made. Adrenal resection and mitotane treatment remain the main form of treatment, with a clear survival benefit. Further research is necessary to determine why mitotane treatment is withheld in a large proportion of patients with advance disease.
