- Complex surgery and radiotherapy are the central pillars of loco-regional oncology treatment. This paper describes the reimbursement schemes used in radiation and complex surgical oncology, reports on literature and policy reviews.A systematic review of the literature of the reimbursement models has been carried out separately for radiotherapy and complex cancer surgery based on PRISMA guidelines. Using searches of PubMed and grey literature, we identified articles from scientific journals and reports published since 2000 on provider payment or reimbursement systems currently used in radiation oncology and complex cancer surgery, also including policy models.Most European health systems reimburse radiotherapy using a budget-based, fee-for-service or fraction-based system; while few reimburse services according to an episode-based model. Also, the reimbursement models for cancer surgery are mostly restricted to differences embedded in the DRG system and adjustments applied to the fees, based on the complexity of each surgical procedure. There is an enormous variability in reimbursement across countries, resulting in different incentives and different amounts paid for the same therapeutic strategy.A reimbursement policy, based on the episode of care as the basic payment unit, is advocated for. Innovation should be tackled in a two-tier approach: one defining the common criteria for reimbursement of proven evidence-based interventions; another for financing emerging innovation with uncertain definitive value. Relevant clinical and economic data, also collected real-life, should support reimbursement systems that mirror the actual cost of evidence-based practice.

- Background: The aim of this meta-analysis is to evaluate the role of sentinel lymph node biopsy (SLNB) in patients with microinvasive breast cancer. Methods: We searched MEDLINE and ISI Web of Science to identify studies including patients with microinvasive breast cancer who underwent SLNB and reported the rate of sentinel-node positivity. We performed proportion meta-analysis using either fixed or random-effects model based on the between-study heterogeneity. Findings: A total of 24 studies including 968 patients met the eligibility criteria. The summary estimate for the sentinel-node (SN) positivity rate was 3.2% (95% Confidence Interval (CI): 2.1%-4.6%), 4.0% (95% CI 2.7%-5.5%), and 2.9% (95% CI: 1.6%-4.6%) for macrometastasis, micrometastasis and isolated tumor cells (ITC) respectively. Significant between-study heterogeneity was observed only in the meta-analysis of ITC positivity rate. Interpretation: The amount of positive sentinel node in patients with proven microinvasive breast cancer is relatively low. As a result, the indications for SLNB in these patients should be probably individualized. (C) 2013 Elsevier Ltd. All rights reserved.

Forskningsöversikt (refereegranskat)abstract
- Several phase I/II studies of chemoradiotherapy for gastric cancer have reported promising results, but the significance of preoperative radiotherapy in addition to chemotherapy has not been proven. In this study, a systematic literature search was performed to capture survival and postoperative morbidity and mortality data in randomised clinical studies comparing preoperative (chemo)radiotherapy or chemotherapy versus surgery alone, or preoperative chemoradiotherapy versus chemotherapy for gastric and/or gastro-oesophageal junction (GOJ) cancer. Hazard ratios (HRs) for overall mortality were extracted from the original studies, individual patient data provided from the principal investigators of eligible studies or the earlier published meta-analysis. The incidences of postoperative morbidities and mortalities were also analysed. In total 18 studies were eligible and data were available from 14 of these. The meta-analysis on overall survival yielded HRs of 0.75 (95% CI 0.65-0.86, P < 0.001) for preoperative (chemo)radiotherapy and 0.83 (95% CI 0.67-1.01, P = 0.065) for preoperative chemotherapy when compared to surgery alone. Direct comparison between preoperative chemoradiotherapy and chemotherapy resulted in an HR of 0.71 (95% CI 0.45-1.12, P = 0.146). Combination of direct and adjusted indirect comparisons yielded an HR of 0.86 (95% CI 0.69-1.07, P = 0.171). No statistically significant differences were seen in the risk for postoperative morbidity or mortality between preoperative treatments and surgery alone, or preoperative (chemo)radiotherapy and chemotherapy. Preoperative (chemo)radiotherapy for gastric and GOJ cancer showed significant survival benefit over surgery alone. In comparisons between preoperative chemotherapy and (chemo)radiotherapy, there is a trend towards improved survival when adding radiotherapy, without increased postoperative morbidity or mortality.

- BACKGROUND: Liver resection provides the best chance for cure in colorectal cancer (CRC) liver metastases. A variety of factors that might influence survival and recurrence have been identified. Predictive models can help in risk stratification, to determine multidisciplinary treatment and follow-up for individual patients. AIMS: To systematically review available prognostic models described for outcome following resection of CRC liver metastases and to assess their differences and applicability. METHODS: The Pubmed, Embase and Cochrane Library databases were searched for articles proposing a prognostic model or risk stratification system for resection of CRC liver metastases. Search terms included 'colorectal', 'liver', 'metastasis', 'resection', 'prognosis' and 'prediction'. The articles were systematically reviewed. RESULTS: Fifteen prognostic systems were identified, published between 1996 and 2009. The median study population was 305 patients and the median follow-up was 32 months. All studies used Cox proportional hazards for multi-variable analysis. No prognostic factor was common in all models, though there was a tendency towards the number of metastases, CRC spread to lymph nodes, maximum size of metastases, preoperative CEA level and extrahepatic spread as representing independent risk factors. Seven models assigned more weight to selected factors considered of higher predictive value. CONCLUSION: The existing predictive models are diverse and their prognostic factors are often not weighed according to their impact. For the development of future predictive models, the complex relations within datasets and differences in relevance of individual factors should be taken into account, for example by using artificial neural networks.

- The past two decades have brought tremendous changes to the practice of radiation oncology and medical oncology. To manage all the complexities related to the new technologies and the new drugs, the radiation and medical oncologists have to enhance their clinical action and professional skill profile. To accomplish this they have to find reliable tools in the quality of their medical practice and in future research activities. Quality assurance (QA) and quality control (QC) for radiation and medical oncologists mean to clarify the different components of the clinical decision, to supervise with proper methodology the required steps needed to accomplish the agreed outcomes and to control them. Quality for radiation and medical oncology means to supervise each clinical and technical component of the whole process to guarantee that all steps together will arrive at the final and best possible outcome. Key components are guidelines, specialization and a multidisciplinary approach. The research of global quality could represent a further complexity, but it is the best tool to give a perspective and a chance to further improvements of our disciplines and to promote better outcome in all cancer patients.

Forskningsöversikt (refereegranskat)abstract
- Recently, Peritoneal Surface Oncology Group International (PSOGI) developed a novel comprehensive treatment consisting of cytoreductive surgery (CRS) and perioperative chemotherapy (POC) for the treatment of peritoneal metastases (PM) from gastric cancer with curative intent. This article reviews the results of this treatment and verifies its indication. In this strategy, peritoneal cancer index (PCI) is determined by laparoscopy, and a peritoneal port is placed. Neoadjuvant bidirectional intraperitoneal/systemic chemotherapy (NIPS) is performed for 3 cycles, and then laparotomy is performed. Cytoreductive surgery with peritonectomy procedures and hyperthermic intraperitoneal chemoperfusion (HIPEC) are performed. Multivariate analyses showed that completeness of cytoreduction, pathologic response to NIPS and PCI level and cytologic status after NIPS, as independent prognostic factors. PCI less than cut-off level after NIPS, negative cytology after NIPS, and positive response to NIPS were identified as the indications for comprehensive treatment. Patients who hold these criteria should be considered as the candidates for CRS and HIPEC.

Forskningsöversikt (refereegranskat)abstract
- Introduction: Clinical Quality Registries (CQRs) were initiated in order to compare clinical outcomes between hospitals or regions within a country. To get an overview of these CQRs worldwide the aim of this study was to identify these CQRs for gynecological oncology and to summarize their characteristics, processes and QI's and to establish whether it is feasible to make an international comparison in the future. Methods: To identify CQRs in gynecological oncology a literature search in Pubmed was performed. All papers describing the use of a CQR were included. Administrative, epidemiological and cancer registries were excluded as these registries do not primarily serve to measure quality of care through QI's. The taskforce or contact person of the included CQR were asked to participate and share information on registered items, processes and indicators. Results: Five nations agreed to collaborate: Australia, Denmark, Italy, the Netherlands and Sweden. Denmark, Netherlands and Sweden established a nationwide registry, collecting data on multiple tumor types, and various QI's. Australia and Italy included patients with ovarian cancer only. All nations had a different process to report feedback results to participating hospitals. Conclusion: CQRs serve the same purpose to improve quality of care but vary on different aspects. Although similarities are observed in the topics measured by the QI's, an international comparison was not feasible as numerators or denominators differ between registries. In order to compare on an international level it would be useful to harmonize these registries and to set an international standard to measure the quality of care with similar indicators.

- Pseudomyxoma Peritonei (PMP) and Peritoneal Mesothelioma (PM) are both rare peritoneal malignancies. Currently, affected patients may be treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy offering long-term survival or even cure in selected patients. However, many issues regarding the optimal treatment strategy are currently under debate. To aid physicians involved in the treatment of these patients in clinical decision making, the PSOGI executive committee proposed to create a consensus statement on PMP and PM. This manuscript describes the methodology of the consensus process. The Delphi technique is a reliable method for attaining consensus on a topic that lacks scientific evidence through multiple voting rounds which feeds back responses to the participants in between rounds. The GRADE system provides a structured framework for presenting and grading the available evidence. Separate questionnaires were created for PMP and PM and sent during two voting rounds to 80 and 38 experts, respectively. A consensus threshold of 51.0% was chosen. After the second round, consensus was reached on 92.9%–100.0% of the questions. The results were presented and discussed in the plenary session at the PSOGI 2018 international meeting in Paris. A third round for the remaining issues is currently in progress. In conclusion, using the Delphi technique and GRADE methodology, consensus was reached in many issues regarding the treatment of PM and PMP amongst an international panel of experts. The main results will be published in the near future.
