Abstract
Deciphering cellular components and the spatial interaction network of the tumor immune microenvironment (TIME) of solid tumors is pivotal for understanding biologically relevant cross-talks and, ultimately, advancing therapies. Multiplexed tissue imaging provides a powerful tool to elucidate spatial complexity in a holistic manner. We established and cross-validated a comprehensive immunophenotyping panel comprising over 121 markers for multiplexed tissue imaging using MACSima™ imaging cyclic staining (MICS) alongside an end-to-end analysis workflow. Applying this panel and workflow to primary cancer tissues, we characterized tumor heterogeneity, investigated potential therapeutical targets, conducted in-depth profiling of cell types and states, sub-phenotyped T cells within the TIME, and scrutinized cellular neighborhoods of diverse T cell subsets. Our findings highlight the advantage of spatial profiling, revealing immunosuppressive molecular signatures of tumor-associated myeloid cells interacting with neighboring exhausted, PD1high T cells in the TIME of hepatocellular carcinoma (HCC). This study establishes a robust framework for spatial exploration of TIMEs in solid tumors and underscores the potency of multiplexed tissue imaging and ultra-deep cell phenotyping in unraveling clinically relevant tumor components.

Abstract
OBJECTIVE The prognostic significance of positive peritoneal cytology in endometrial cancer has long been debated. In 2009, the Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) removed cytology as a staging criterion from the endometrial cancer staging system. However, there is still evidence that positive peritoneal cytology may decrease survival among patients with endometrial cancer. The aim of this study was to determine the prognostic significance of positive peritoneal cytology among the different molecular subgroups. METHODS This study included patients with endometrial cancer who underwent primary surgical treatment between 2004 and 2015 at the Bern University Hospital, Switzerland, with molecular classification of the primary tumor and peritoneal cytology performed. RESULTS A total, 250 patients with endometrial cancer were enrolled. Peritoneal cytology was assessed in 206 patients, of whom 24% were positive: 25% of the POLEmut, 16% of the MMRd, 41% of the p53abn, and 24% of the NSMP cases. The mean follow-up was 128.7 months. Presence of positive peritoneal cytology was associated with significantly decreased mean recurrence-free and overall survival in patients with p53abn (p = .003 and p = .001) and NSMP (p = .020 and p = .049) endometrial cancer. In multivariable Cox regression analysis, positive peritoneal cytology remained an independent predictor of recurrence (p = .033) and death (p = .008) in p53abn endometrial cancer patients. CONCLUSION Positive peritoneal cytology is associated with worse oncologic outcomes in NSMP and p53abn endometrial cancer and remains an independent predictor of recurrence and death in patients with p53abn endometrial cancer.

Abstract
Lynch syndrome is an inherited tumor syndrome caused by a pathogenic germline variant in DNA mismatch repair genes. As the leading cause of hereditary endometrial cancer, international guidelines recommend universal screening in women with endometrial cancer. However, testing for Lynch syndrome is not yet well established in clinical practice. The aim of this study was to evaluate adherence to our Lynch syndrome screening algorithm. A retrospective, single-center cohort study was conducted of all endometrial cancer patients undergoing surgical treatment at the Bern University Hospital, Switzerland, between 2017 and 2022. Adherence to immunohistochemical analysis of mismatch repair status, and, if indicated, to MLH1 promoter hypermethylation and to genetic counseling and testing was assessed. Of all 331 endometrial cancer patients, 102 (30.8%) were mismatch repair-deficient and 3 (0.9%) patients were diagnosed with Lynch syndrome. Overall screening adherence was 78.2%, with a notable improvement over the six years from 61.4% to 90.6%. A major reason for non-adherence was lack of provider recommendation for testing, with advanced patient age as a potential patient risk factor. Simplification of the algorithm through standardized reflex screening was recommended to provide optimal medical care for those affected and to allow for cascading testing of at-risk relatives.

Abstract
BACKGROUND SLN mapping has emerged as a standard of care in endometrial cancer due to its high sensitivity and significant reduction in morbidity. Although lymphovascular space invasion (LVSI) is a known risk factor for lymph node metastasis and recurrence, evidence on the reliability of SLN mapping in LVSI-positive patients is scarce. The aim of this study was to determine the impact of LVSI on the diagnostic performance of SLN mapping. METHODS This retrospective cohort study included patients with endometrial cancer who underwent primary surgical treatment at the Bern University Hospital, Switzerland, between 2012 and 2022. RESULTS LVSI was present in 22% of patients and was significantly associated with lymph node metastasis (p < 0.001) and recurrence (p < 0.001). In node-negative patients with only SLN mapping performed, LVSI was an independent predictor of recurrence during multivariable Cox regression analysis (p = 0.036). The negative predictive value of SLN mapping was 91.5% and was significantly lower in tumors with LVSI (75.0%) compared to LVSI-negative tumors (95.6%, p = 0.004). CONCLUSION The presence of LVSI was significantly associated with worse oncological outcomes. LVSI was an independent predictor of recurrence in node-negative patients with only SLN mapping performed. Furthermore, the negative predictive value of SLN mapping was significantly lower in LVSI-positive tumors.

Abstract
INTRODUCTION The Peritoneal Regression Grading Score (PRGS) is a 4-tied histologic regression grading score for determining the response of peritoneal metastasis to chemotherapy. Peritoneal biopsies in every abdominal quadrant are recommended. A positive therapy response is defined as a decreasing or stable mean PRGS between 2 therapy cycles. The added value of periodic acid satin (PAS) and Ber-EP4 staining over HE staining for diagnosing PRGS1 (the absence of vital tumor cells) is unclear. MATERIALS AND METHODS A total of 339 biopsies obtained during 76 laparoscopies in 33 patients with peritoneal metastasis of gastric cancer were analyzed. Biopsies classified as PRGS 1 (no residual tumor, n=95) or indefinite (n=50) were stained with PAS, and remaining indefinite or PRGS1 cases additionally stained with BerEP4. RESULTS After PAS-staining tumor cells were detected in 28 out of 145 biopsies (19%), the remaining 117 biopsies were immunostained with Ber-EP4. Tumor cells were detected in 22 biopsies (19%). In total, additional staining allowed the detection of residual tumor cells in 50 out of 339 biopsies (15%) and changed the therapy response assessment in 7 out of 33 (21%) patients. CONCLUSIONS In summary, 25% (24 out of 95) of initially tumor-free samples (PRGS1) showed residual tumor cells after additional staining with PAS and/or BerEp4. Immunohistochemistry provided important additional information (the presence of tumor cells) in 22 of all 339 biopsies (11.2%). Further staining reduced the instances of unclear diagnosis from 50 to 0 and changed the therapy response assessment in 7 out of 33 patients (21%). We recommend additional staining in PRGS1 or unclear cases.

Abstract
Objectives The peritoneal regression grading score (PRGS) is a four-tied pathologic score measuring tumor regression in biopsies from patients with peritoneal metastasis (PM) receiving chemotherapy. Methods This retrospective analysis of a prospective registry (NCT03210298) analyses 97 patients with isolated PM under palliative chemotherapy. We examined the predictive value of the initial PRGS for overall survival (OS) and the prognostic value of PRGS in repeated peritoneal biopsies. Results The 36 (37.1 %) patients with an initial mean PRGS≤2 had a longer median OS (12.1 months, CI 95 % 7.8-16.4) vs. 8.0 months (CI 95 % 5.1-10.8 months) in 61 (62.9 %) patients with PRGS≥3 (p=0.02) After stratification, the initial PRGS was an independent predictor of OS (Cox-regression, p<0.05). Out of 62 patients receiving≥two chemotherapy cycles, 42 (67.7 %) had a histological response (defined as a lower or stable mean PRGS in successive therapy cycles), and 20 (32.3 %) progressed (defined as an increasing mean PRGS). PRGS response was associated with a longer median OS (14.6 months, CI 5-95 % 6.0-23.2) vs. 6.9 (CI 5-95 % 0.0-15.9) months. PRGS response was prognostic in the univariate analysis (p=0.017). Thus, PRGS had both a predictive and prognostic significance in patients with isolated PM receiving palliative chemotherapy in this patient cohort. Conclusions This is the first evidence for the independent predictive and prognostic significance of PRGS in PM. These encouraging results need validation in an adequately powered, prospective study.

Abstract
Objectives The four-tied peritoneal regression grading score (PRGS) is increasingly used to evaluate the response of peritoneal metastases (PM) to chemotherapy. The minimal number of peritoneal biopsies needed for PRGS determination remains unclear. Methods A prospective cohort of 89 PM patients treated with 210 pressurized intraperitoneal aerosol chemotherapy (PIPAC) cycles was investigated. Four biopsies from every abdominal quadrant were recommended. Histological tumor response was defined as a stable or decreasing mean PRGS between therapy cycles, progression increasing. We compared the diagnostic uncertainty induced by missing biopsies to the histological response. Results A total of 49 patients had at least two PIPAC and were eligible for therapy response assessment. Mean PRGS decreased from 2.04 (CI 5-95% 1.85-2.27) to 1.79 (CI 5-95% 1.59-2.01), p=0.14, as a proof of therapy effectiveness. 35 (71.4%) patients had a stable or decreasing PRGS (therapy response), 14 (28.6%) a PRGS increase (disease progression). Histology showed agreement between four biopsies in 42/210 laparoscopies (20%), between ≥3 biopsies in 103 (49%), and between ≥2 biopsies in 169 laparoscopies (81%). Mean loss of information with one missing biopsy was 0.11 (95% CI=0.13) PRGS points, with two missing biopsies 0.18 (95% CI 0.21). In 9/49 patients (18.3%), the loss of information with one less biopsy exceeded the change in PRGS under therapy. Conclusions A minimum of three biopsies is needed to diagnose PM progression with an accuracy superior to 80%. Missing biopsies often result in a false diagnosis of tumor progression.

Abstract
125 Background: Pressurized intraperitoneal aerosolized chemotherapy (PIPAC) is being evaluated as a novel minimally invasive palliative treatment of peritoneal metastases (PM). Prior studies have established the feasibility and safety of repeated PIPAC treatments in gastrointestinal and gynecologic cancers. The goal of the present phase 1 trial was to establish the safety and feasibility of PIPAC oxaliplatin in a highly chemotherapy refractory colorectal and appendiceal cancer patient population. Methods: Patients with biopsy-proven peritoneal metastases from colorectal or appendiceal cancer underwent up to three PIPAC treatments using oxaliplatin (92 mg/m2) with a six-week interval at two academic centers. Patients with bowel obstruction, extra-peritoneal metastases, or poor performance status (ECOG>2) were excluded. PIPAC was nebulized over 5 min with a 30 min aerosol dwell time. Apart from the first PIPAC cycle, the patients also received a sensitizing dose of 5FU/LV (400mg/m2) within 24 hours of the procedure. Primary end point was safety as assessed by dose limiting toxicities within 6 weeks of the first PIPAC. Secondary endpoints included safety with the addition of 5FU/LV, efficacy, surgical morbidity, technical failure rate, progression-free and overall survival, pharmacokinetics (PK), and quality of life assessment. Results: A total of 8 patients were included: 5 colorectal; and 3 appendiceal. Median number of prior chemotherapy cycles was 2 (Interquartile range – IQR; 1.5-3.5). All patients were refractory to systemic oxaliplatin-based chemotherapy. Median time from diagnosis to PIPAC was 16 months (IQR; 5.6, 17.5) and Peritoneal Carcinomatosis Index was 29 (IQR; 20.5, 31.5). Five (62.5%) patients completed 3 PIPAC cycles while in 3 (37.5%) patients PIPAC was discontinued due to disease progression within the peritoneal cavity. No surgical complication or dose limiting toxicity was observed. Only one patient developed grade 3 treatment-related toxicity after first PIPAC (anemia), and another patient after second PIPAC (abdominal pain and anemia). At the completion of PIPAC treatment 5 patients had stable disease and 3 had disease progression. Pharmacokinetic, histologic response and preliminary survival data will be presented at the meeting. Conclusions: PIPAC with oxaliplatin is safe and feasible in a highly chemotherapy refractory cohort of appendiceal and colorectal carcinomatosis patients with or without sensitizing 5-FU/ LV. Clinical trial information: NCT04329494.

Abstract
ABSTRACT Incidental findings of thyroid lesions, some of which show increased FDG uptake, are common in whole-body FDG PET/CT imaging of oncological patients. As metastases to the thyroid are extremely rare, it is often a matter of debate, whether thyroid lesions should be considered as benign goiter or evaluated further. Here, we present the case of a 65-year-old woman with history of small cell lung cancer and multiple thyroid lesions, classified as benign nodular goiter. Because in restating using 18F-FDG PET/CT these lesions showed an increased FDG uptake and growth progression, decision was made for fine-needle aspiration, which revealed small cell lung cancer metastasis 14 months after first tumor diagnosis.

Abstract
BACKGROUND Phosphoglycerate kinase 1 (PGK1) plays metabolic, kinase and translational roles in Peritoneal metastasis (PM) of gastric origin and is associated with chemoresistance. Silencing PGK1 might potentiate the effect of chemotherapy. METHODS In an orthoptic xenograft nude mice model, human gastric cancer cells (MKN45) were grown in 22 donor animals. Solid tumors were then grafted into the gastric subserosa of 102 recipient animals and allowed to grow for 10 days. Animals were randomized into 7 groups: Five test groups: 1) Mitomycin C (MMC), 2) MMC and small hairpin RNA silencing of PGK1 with an adenoviral vector (Adv-shPGK1), 3) 5-fluorouracil (5-FU), 4) 5-FU and Adv-shPGK1, 5) Adv-shPGK1 alone; two control groups: 1) Sham (NaCl 0.9%), 2) empty viral vector. Intraperitoneal therapy was administered on postoperative day (POD) 11 and 18. Animals were sacrificed at POD 21, analysis was blinded to therapy. RESULTS Adding Adv-shPGK1 to 5-FU reduced the number (0.23 ± 0.43 vs. 1.36 ± 1.00, p = 0.005) and weight (0,005 ± 0.012 mg vs. 0.05 ± 0.08 mg, p = 0.002) of PM as compared to 5-FU alone. The effect of adding Adv-shPGK1 to MMC did not reach statistical significance. Mortality was not increased by adding Adv-shPGK1 to chemotherapy but was increased by Adv-shPGK1 alone as compared to sham. CONCLUSION In this experimental model, combined therapy with chemotherapy and Adv-shPGK1 improves control of PM of gastric origin as compared to chemotherapy alone and might counteract chemoresistance of PM. A systemic toxicity of Adv-shPGK1 cannot be excluded.

Abstract
BACKGROUND Optimization of intraperitoneal drug delivery systems requires functional models. We proposed the Inverted Bovine Urinary Bladder Model (IBUB), but IBUB does not allow repeated measurements over time and there is a significant biological variability between organs. METHODS A further development of IBUB is presented, based on the physical principle of communicating vessels. Fresh bovine bladders were inverted so that the peritoneum lines up the inner surface. The IBUB and a second vessel were then interconnected under the same CO2 pressure and placed on two scales. The therapeutic solution (Doxorubicin 2.7 mg and Cisplatin 13.5 mg) was delivered via an aerosolizer. All experiments were in triplicate and blinded to the origin of samples, measurements in a GLP-certified laboratory. RESULTS The enhanced IBUB (eIBUB) model allows measurements of tissue drug concentration, depth of tissue penetration and spatial distribution. The homogeneous morphology of the peritoneum enables standardized, multiple tissue sampling. eIBUB minimizes biological variability between different bladders and eliminates the bias caused by the liquid collecting at the bottom of the model. Concentration of doxorubicin in the eIBUB (mean ± STDV: 18.5 ± 22.6 ng/mg) were comparable to clinical peritoneal biopsies (19.2 ± 38.6 ng/mg), as was depth of drug penetration (eIBUB: mean (min-max) 433 (381-486) µm, clinical ~ 500 µm). CONCLUSIONS The eIBUB model is a simple and powerful ex vivo model for optimizing intraperitoneal drug delivery and represents an attractive alternative to animal models. Results obtained are similar to those obtained in the human patient.

Abstract
Background: Efficacy of second-line systemic chemotherapy in recurrent gastric cancer with peritoneal metastasis (RGCPM) is limited. We assessed the feasibility, safety and possible efficacy of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in patients with RGCPM after ⩾1 line of palliative intravenous chemotherapy. Methods: In this open-label, single-arm, monocentric phase II ICH-GCP clinical trial, patients were scheduled for three courses of PIPAC with cisplatin 7.5 mg/m2 and doxorubicin 1.5 mg/m2 (PIPAC C/D) every 6 weeks. Patients with bowel obstruction or extraperitoneal metastasis were ineligible. The primary endpoint was clinical benefit rate (CBR) by Response Evaluation Criteria in Solid Tumors based on clinical records. Secondary endpoints included overall survival (OS), median time to progression (TTP), peritoneal carcinomatosis index (PCI), histological regression and ascites volume. Safety and tolerability were assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 4, quality of life (QoL) by EORTC-QLQ30 questionnaire. Results: A total of 25 patients were enrolled and available for the analysis of the primary endpoint. Of those 25 patients, 10 (40%) had a radiological complete, partial response or stable disease. Median OS [intention to treat (ITT)] was 6.7 months, median TTP was 2.7 months. Complete or major regression on histology were observed in 9/25 patients (36%, ITT) or 6/6 [100%, per protocol (PP)] patients. There were no suspected unexpected serious adverse reactions, no treatment-related deaths, no CTCAE grade 4 toxicity and three (12%) grade 3 toxicities. Changes in the QLQ-C30 scores during PIPAC C/D therapy were small and not significant. Conclusions: PIPAC C/D was well tolerated and active in patients with RGCPM. Survival was encouraging. Randomized controlled trials should now be designed in this indication.

Abstract
AIMS The four-tiered peritoneal regression grading score (PRGS) assesses the response to chemotherapy in peritoneal metastasis (PM). The PRGS is used, for example, to assess the response to pressurised intraperitoneal aerosol chemotherapy (PIPAC). However, the reproducibility of the PRGS is currently unknown. We aimed to evaluate the inter- and intraobserver variability of the PRGS. METHODS AND RESULTS Thirty-three patients who underwent at least three PIPAC treatments as part of the PIPAC-OPC1 or PIPAC-OPC2 clinical trials at Odense University Hospital, Denmark, were included. Prior to each therapy cycle, peritoneal quadrant biopsies were obtained and three haematoxylin and eosin (H&E)-stained step sections were scanned and uploaded to a pseudonymised web library. For determining interobserver variability, eight pathologists assessed the PRGS for each quadrant biopsy, and Krippendorff's alpha and intraclass correlation coefficients (ICCs) were calculated. For determining intraobserver variability, three pathologists repeated their own assessments and Cohen's kappa and ICCs were calculated. A total of 331 peritoneal biopsies were analysed. Interobserver variability for PRGS of each biopsy and for the mean and maximum PRGS per biopsy set was moderate to good/substantial. The intraobserver variability for PRGS of each biopsy and for the mean and maximum PRGS per biopsy set was good to excellent/almost perfect. CONCLUSIONS Our data support the PRGS as a reproducible and useful tool to assess response to intraperitoneal chemotherapy in PM. Future studies should evaluate the prognostic and predictive role of the PRGS.

Abstract
Detachment of cells from the extracellular matrix into the peritoneal cavity initiates a cascade of metabolic alterations, leading usually to cell death by apoptosis, so-called anoikis. Glycolytic enzymes enable the switch from oxidative phosphorylation to aerobic glycolysis and allow resistance to anoikis of shed tumour cells. These enzymes also have moonlighting activities as protein kinases and transcription factors. Phosphoglycerate kinase (PGK) and pyruvate kinase are the only glycolytic enzymes generating ATP in the hexokinase pathway. Hypoxia, EGFR activation, expression of K-Ras G12V and B-Raf V600E induce mitochondrial translocation of phosphoglycerate kinase 1 (PGK1). Mitochondrial PGK1 acts as a protein kinase to phosphorylate pyruvate dehydrogenase kinase 1 (PDHK1), reducing mitochondrial pyruvate utilization, suppressing reactive oxygen species production, increasing lactate production and promoting tumourigenesis. PGK1 also plays a role as a transcription factor once transported into the nucleus. Resistance to anoikis is also facilitated by metabolic support provided by cancer-associated fibroblasts (CAFs). Our series of experiments in-vitro and in the animal model showed that PGK1 knock-out or inhibition is effective in controlling development and growth of peritoneal metastasis (PM) of gastric origin, establishing a causal role of PGK1 in this development. PGK1 also increases CXCR4 and CXCL12 expression, which is associated with a metastatic phenotype and plays a role in the metastatic homing of malignant cells. Thus, PGK1, its modulators and target genes may be exploited as therapeutic targets for preventing development of PM and for enhancing cytotoxic effects of conventional systemic chemotherapy.

Abstract
INTRODUCTION Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel drug delivery system with superior pharmacological properties for treating peritoneal metastasis (PM). Safety and efficacy results of PIPAC with cisplatin/doxorubicin or oxaliplatin from a registry cohort are presented. METHODS IRB-approved registry study. Retrospective analysis. No predefined inclusion criteria, individual therapeutic recommendation by the interdisciplinary tumor board. Safety assessment with CTCAE 4.0. Histological assessment of tumor response by an independent pathologist using the 4-tied peritoneal regression grading system (PRGS). Mean PRGS and ascites volume were assessed at each PIPAC. RESULTS A total of 142 PIPAC procedures were scheduled in 71 consecutive patients with PM from gastric (n = 26), colorectal (n = 17), hepatobiliary/pancreatic (n = 9), ovarian (n = 6), appendiceal (n = 5) origin, pseudomyxoma peritonei (n = 4), and other tumors (n = 3). Mean age was 58 ± 13 years. Patients were heavily pretreated. Mean PCI was 19 ± 13. Laparoscopic nonaccess rate was 11/142 procedures (7.7%). Mean number of PIPAC/patient was 2. All patients were eligible for safety analysis. There was no procedure-related mortality. There were 2.8% intraoperative and 4.9% postoperative complications. 39 patients underwent more than one PIPAC and were eligible for efficacy analysis, and PRGS could be assessed in 36 of them. In 24 patients (67%), PRGS improved or remained unchanged at PIPAC#2, reflecting tumor regression or stable disease. Ascites was present in 24 patients and diminished significantly under therapy. Median survival was 11.8 months (95% CI: 7.45-16.2 months) from PIPAC#1. CONCLUSION PIPAC is feasible, safe, and well-tolerated and can induce histological regression in a significant proportion of pretreated PM patients. This trial is registered with NCT03210298.

Abstract
The peritoneal cavity (cavum peritonei) is incompletely divided into spaces and recessus (or fossae), which are playing an important role in health and disease. Peritoneal subspaces are determined by the parietal attachments of the abdominal organs, the ligaments and mesenteries. These include the splenorenal, the falciform, the triangular, the gastrosplenic, the phrenicocolic and the gastrocolic ligaments; the greater omentum and the lesser omentum (formed by the gastrohepatic and hepatoduodenal ligaments); the small bowel mesenterium and the mesocolon. These ligaments and mesenteries divide the peritoneal cavity into several distinct anatomic and functional regions. The supramesocolic compartment is divided into a bilateral subphrenic space and a subhepatic space continuing into the lesser sac (bursa omentalis). The inframesolic compartment is divided into a left and right region by the mesentery. The right paracolic gutter communicates with the pelvis and with the right suphrenic space. The left paracolic gutter is separated from the left subphrenic space by the phrenocolic ligament. The peritoneal space is virtual, is completely occupied by the intraabdominal organs and can only be visualized by radiological means in the presence of air (organ perforation), liquid (ascites, pus, bile, gastrointestinal fluids) or tumor invasion. Peritoneal morphology has numerous pathophysiological implications: it impacts on the propagation of intraabdominal infections, determines the spreading of peritoneal metastasis and can cause bowel volvulus. Internal hernias can arise at the junction between intraperitoneal and extraperitoneal bowel segments, in particular into the left paraduodenal recessus. Knowledge of peritoneal morphology is a precondition for developing locoregional therapeutic strategies in peritoneal disease and for effective peritoneal dialysis.

Abstract
The peritoneum consists of a layer of mesothelial cells on a connective tissue base which is perfused with circulatory and lymphatic vessels. Total effective blood flow to the human peritoneum is estimated between 60 and 100 mL/min, representing 1-2 % of the cardiac outflow. The parietal peritoneum accounts for about 30 % of the peritoneal surface (anterior abdominal wall 4 %) and is vascularized from the circumflex, iliac, lumbar, intercostal, and epigastric arteries, giving rise to a quadrangular network of large, parallel blood vessels and their perpendicular offshoots. Parietal vessels drain into the inferior vena cava. The visceral peritoneum accounts for 70 % of the peritoneal surface and derives its blood supply from the three major arteries that supply the splanchnic organs, celiac and superior and inferior mesenteric. These vessels give rise to smaller arteries that anastomose extensively. The visceral peritoneum drains into the portal vein. Drugs absorbed are subject to first-pass hepatic metabolism. Peritoneal inflammation and cancer invasion induce neoangiogenesis, leading to the development of an important microvascular network. Anatomy of neovessels is abnormal and characterized by large size, varying diameter, convolution and blood extravasation. Neovessels have a defective ultrastructure: formation of large "mother vessels" requires degradation of venular and capillary basement membranes. Mother vessels give birth to numerous "daughter vessels". Diffuse neoangiogenesis can be observed before appearance of macroscopic peritoneal metastasis. Multiplication of the peritoneal capillary surface by neoangiogenesis surface increases the part of cardiac outflow directed to the peritoneum.

Abstract
Background Adult granulosa cell tumor of the ovary (AGCT) is a rare functional sex-cord-stromal ovarian neoplasm characterized by low malignant potential and late relapse. Evidence-based management options for women with recurrent AGCT are limited. Case report We present the case of a 60-year-old woman with the fifth recurrence of AGCT initially diagnosed 19 years ago. After initial surgery in 1996, the patient underwent four additional surgical interventions for recurrent disease in 2005 (abdominal wall), 2009 (abdominal wall), 2010 (paravesical), and 2011 (paravesical). In 2011, she underwent pelvic irradiation with 50.5 Gray. In 2015, another recurrence was diagnosed based on an increase of serum inhibin and a tumor seen on CT scan in the right upper abdomen. The patient underwent cytoreductive surgery (CRS) with complete cytoreduction followed by hyperthermic intraperitoneal chemotherapy (HIPEC) with cisplatin 50 mg/m2 and doxorubicin 15 mg/m2. No intra- or post-operative complications occurred. Final histology revealed recurrent AGCT with 6 cm in the largest diameter. Subsequently, antihormonal treatment with anastrozole 1.5 mg per day was prescribed. With a follow-up of six months, the patient is well and alive. Conclusion CRS and HIPEC are a reasonable treatment option for selected women with recurrent AGCT limited to the abdomen. AGCT accounts for < 5% of ovarian neoplasms. AGCT has a good prognosis with overall survival rates of 87% and 76% after 5 and 10 years. A third of patients with AGCT experience recurrence with a median time interval of 12 years. Surgery, chemotherapy, and hormonal therapy are available for recurrent AGCT. CRS and HIPEC are feasible and potentially effective in recurrent AGCT.

Abstract
Background: Multimodal therapeutic strategies have improved the outcome of peritoneal metastases (PM). However, objective assessment of therapy response remains difficult in PM, since radiological studies have a poor accuracy for low-volumetric disease. There is an obvious need for a histological gold standard allowing assessment of tumor response to treatment in PM. Content: We propose to perform peritoneal punch biopsies with a diameter of 3 to 5 mm in all four abdominal quadrants. We propose a four-tier Peritoneal Regression Grading Score (PRGS), defined as Grade 1: complete response (absence of tumor cells), Grade 2: major response (major regression features, few residual tumor cells), Grade 3: minor response (some regressive features but predominance of residual tumor cells), Grade 4: no response (tumor cells without any regressive features). Acellular mucin and infarct-like necrosis should be regarded as regression features. We recommend reporting the mean and the worst value of the regression grades obtained. When complete tumor response is suspected intraoperatively, a peritoneal cytology should be sampled. Summary: A generic, unique score for the assessment of histological tumor response to chemotherapy in PM makes sense because of the clinical impact of histological response to therapy and because the organ of metastasis (peritoneum) is the same. By adopting PRGS, different centers will be able to use a uniform terminology and grading that will allow meaningful comparison of their results. Outlook: PRGS has now to be validated in several gastrointestinal and gynecological cancer types and may be useful both in clinical and research settings.

Abstract
AIM We aimed to assess the objective tumor response (OTR) to laparoscopic pressurized intraperitoneal aerosol chemotherapy (PIPAC) in women with peritoneal carcinomatosis (PC). PATIENTS AND METHODS We carried-out a retrospective cohort study of women with PC undergoing repeated courses of PIPAC with 7.5 mg/m(2) of cisplatin and 1.5 mg/m(2) of doxorubicin. OTR was defined as histological regression. Peritoneal carcinomatosis index (PCI) improvement on video-laparoscopy and ascites volume reduction were secondary outcomes. Quality of life was assessed by the European Organization for Research & Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-30+3. RESULTS A total of 252 PIPACs were performed in 99 women with PC and ovarian (n=84), primary peritoneal (n=6), cervical (n=3), endometrial (n=3), fallopian tube (n=1), and breast (n=1) cancer and pseudomyxoma peritonei (n=1). Laparoscopic non-access rate was 17% (17/99). Fifty women had more than one PIPAC procedures, with an OTR of 76% (38/50) and PCI improvement in 64% (32/50). Ascites volume significantly decreased from 762±1170 ml to 167±456 ml (p=0.02). A high initial Karnofsky Index was correlated with receiving more than one PIPAC (p<0.0001) and a high number of previous surgeries with laparoscopic non-access (p=0.01). Twenty adverse events of Common Terminology Criteria for Adverse Events grade 3 or more were noted. Absence of ascites (odds ratio=8.45, 95% confidence interval=1.9-3.6; p<0.0001), but not patient age, serum cancer antigen-125, and Karnofsky Index independently predicted OTR. EORTC QLQ-30+3 scores for global physical health, nausea/vomiting, appetite loss, and constipation improved during therapy. CONCLUSION PIPAC with cisplatin and doxorubicin is an active treatment in women with PC and preserves quality of life. Appropriate patient selection regarding performance status and the number of prior surgeries is important.

Abstract
Metastasis of ovarian cancer to the breast (MOCB) is a rare event. Clinical presentations of MOCB vary and surgery is the mainstay of treatment. The current study presents two cases of MOCB in women with recurrent ovarian cancer first diagnosed in April 2011 and October 2013, respectively. The patients presented to the clinic with a localized, palpable, painful mass in the upper outer quadrant of the right breast and a centrally localized, palpable, painful mass of the left breast, respectively. Breast sonography and mammography showed a singular, round, homogenous tumor with irregular borders in each case. An ipsilateral enlarged axillary node was palpable in one case. Tumor biopsy revealed an undifferentiated adenocarcinoma of unknown origin in one case and a moderately-differentiated adenocarcinoma suspected to be breast cancer in the other case. Tumor cells were positive for estrogen receptor and paired box 8, and negative for GATA binding protein 3 in the two cases. Palliative mastectomy was performed in one case and lumpectomy with ipsilateral axillary sentinel node biopsy in the other case, and the final histology revealed MOCB in each. The post-operative course of the disease was uneventful and the patients continued with their ovarian cancer-specific chemotherapy. One patient succumbed to disease progression 2 months after breast surgery. The other patient remains alive and is currently undergoing systemic chemotherapy. The current study also presents a review of 110 cases of MOCB identified in a literature search of Pubmed. Data from these studies, including the clinical and histological characteristics of MOCB, and the clinical management and prognosis are discussed. Overall, MOCB is rare, with distinct clinical and histological features. The disease is usually treated with local surgical excision or mastectomy and has a poor prognosis.

Abstract
Background: Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a drug delivery technique with superior pharmacological properties for treating peritoneal metastasis (PM). Adding electrostatic loading (ePIPAC) as an adjunct to aerosol and artificial hydrostatic pressure improved tissue uptake in a preclinical model. Methods: We report the first ePIPAC use in 3 patients with PM of hepatobiliary-pancreatic (HBP) origin. All 3 patients received concomitant palliative systemic chemotherapy that was discontinued in two patients. PIPAC with cisplatin 7.5 mg/m2 and doxorubicin 1.5 mg/m2 was applied intraperitoneally at a pressure of 12 mmHg and a temperature of 37% °C for 30 min. Additionally, a voltage 7,500-9,500 V and a current≤10 µA were applied over a stainless steel brush electrode emitting a stream of electrons. Results: ePIPAC was technically feasible. No intraoperative complication was noted. The procedures were well tolerated with no adverse event CTCAE > 2. Patient 1 with PM of unknown origin (CUP with HBP phenotype) showed an objective histological and radiological response and survived 11 months. Patient 2 with ductal pancreatic cancer underwent secondary resection after ePIPAC with no residual PM; however, tumor recurred 5 months later. Patient 3 with adenocarcinoma of the gallbladder showed a radiological regression of liver infiltration and is alive after 22 months without histological evidence of PM. Conclusion: ePIPAC is technically feasible, is well tolerated and can induce tumor regression of PM in HBP cancers with and without concomitant systemic chemotherapy. These preliminary results justify prospective clinical studies with ePIPAC.

Abstract
Background: Little is known about the nutritional status of patients with peritoneal metastasis (PM), in particular about the evolution of the so-called anorexia-cachexia syndrome in these patients. The objective of the study was to assess nutritional status in PM patients at the end of life, including metabolic aspects. Methods: Observational study. Prospective nutritional status assessment in 87 PM patients, including Subjective Global Assessment: (SGA), physical examination (body mass index [BMI], bioelectrical impedance analysis [BIA], anthropometry and blood chemistry). Results: 85 % patients had received previous chemotherapy. Peritoneal carcinomatosis index was 16±11, Karnofsky 81±14 % and ascites volume 1,000±1,690 ml. SGA was reduced with 22.0±9.6 points, BMI normal with 25.3±5.8 kg/m2 and resting metabolism was 1,527±248 kcal/day. Serum total protein and albumin were at the inferior normal limit (6.5±0.8 g/dl, respectively 3.7±0.8 g/dl) and C-reactive protein (CRP) was elevated (2.9±4.1 g/dl). Serum levels of protein (p=0.05), albumin (p=0.003) and transferrin (p=0.001) were higher in gastrointestinal than in ovarian PM patients. When patients were grouped according to time from first assessment to death, serum protein and albumin decreased until end of life, whereas ascites volume, resting metabolism and CRP increased. Conclusion: Both increased resting metabolism and decreased caloric intake contribute to the development of the cachexia-anorexia syndrome in PM patients. End of life is caused by energetic dysbalance and exhaustion.

Abstract
AIM Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is an experimental drug delivery method that applies chemotherapy into the abdominal cavity as an aerosol under pressure. We present the first results obtained with PIPAC in colorectal peritoneal metastasis (CPM). METHOD This is a retrospective analysis. PIPAC was applied in 17 consecutive patients with pretreated CPM. All patients had previously undergone surgery, and 16 had undergone previous lines of systemic chemotherapy (median, two lines). The mean peritoneal metastasis index (peritoneal cancer index) was 16 ± 10. Forty-eight applications of PIPAC with oxaliplatin (92 mg/m2 ) were given every 6 weeks at 37 °C and 12 mmHg for 30 min. The outcome criteria were microscopic pathological response, survival and adverse events according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. RESULTS Forty-eight PIPAC administrations were performed with no intra-operative complications. The mean number of PIPAC administrations per patient was 2.8 (minimum one, maximum six). Postoperative adverse events (CTCAE level 3) were observed in four patients (23%), no CTCAE level-4 adverse events were reported. The hospital mortality was zero. Objective tumour responses were observed in 12/17 patients (71%), and the overall responses were as follows: complete pathological response (seven patients), major response (four patients), partial response (one patient), no response (two patients) and not eligible (three patients). The mean survival after first PIPAC was 15.7 months. CONCLUSION Repeated PIPAC with oxaliplatin can induce the regression of pretreated CPM. The toxicity appears to be low. These preliminary results are encouraging and justify prospective clinical studies.

Abstract
Background: Adult and juvenile granulosa cell tumors of the ovary are rare functional sex-cord-stromal ovarian neoplasms characterized by low malignant potential and late relapse. Evidence-based management options for primary and recurrent juvenile (JGCT) and adult (AGCT) granulosa cell tumors are limited and treatment options have not been standardized. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) may be an option to treat these women effectively. Methods: Systematic literature review using PubMed and the Cochrane Central Register of Controlled Trials. Results: No reports of HIPEC among women with a first diagnosis of AGCT were identified. We identified 5 reports on the safety and therapeutic efficacy of CRS and HIPEC in 19 patients with recurrent AGCT and one patient with JGCT. The pooled rate of complete cytoreduction was 95 % (18/19) with 16 % (3/19) severe morbidity and no procedure-related mortality. The median time of follow-up was 30 (range, 3 to 72) months, during which 6/19 (31 %) patients experienced a recurrence and two patients (10 %) died of the disease. Conclusion: CRS and HIPEC are a safe and potentially effective treatment option for selected women with recurrent AGCT limited to the abdomen.

Abstract
BACKGROUND AND STUDY AIMS A novel therapeutic concept, pressurized intraluminal aerosol chemotherapy (PILAC), and a corresponding device for distributing drugs to the mucosa and submucosa of the distal esophagus are presented. MATERIALS AND METHODS The endoscopic device that was designed consisted of (i) a double-balloon catheter, similar to a Sengstaken-Blakemore tube; (ii) a carbon dioxide (CO2) line, used to create a gaseous, pressurized environment; and (iii) a micropump, used to generate a therapeutic aerosol. The device was inserted into the distal esophagus in three narcotized Landrace pigs. Dbait (short interfering DNA, or siDNA) was aerosolized under pressure (12 mmHg) in CO2 at 37 °C for 30 minutes. RESULTS The procedure was well tolerated by all animals. At autopsy, no mucosal or muscular tear was observed. Fluorescence microscopy revealed a homogeneous intramural distribution of Dbait-cyanine 5 in the esophageal wall down to the circular muscular layer (400 - 600 µm). CONCLUSIONS PILAC is feasible in a large animal model and appears to be safe. Therapy of the entire "tissue at risk" for the development of cancer in the distal esophagus is possible without the prior endoscopic identification of diseased tissue.

Abstract
BACKGROUND Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel technique of intraperitoneal chemotherapy. First results obtained with PIPAC in patients with advanced peritoneal metastasis (PM) from gastric cancer (GC) are presented. METHODS Retrospective analysis: Sixty PIPAC were applied in 24 consecutive patients with PM from GC. 67 % patients had previous surgery, and 79 % previous platinum-based systemic chemotherapy. Mean Peritoneal Carcinomatosis Index (PCI) of 16 ± 10 and 18/24 patients had signet-ring GC. Cisplatin 7.5 mg/m(2) and doxorubicin 1.5 mg/m(2) were given for 30 min at 37 °C and 12 mmHg at 6 week intervals. Outcome criteria were survival, adverse events, and histological tumor response. RESULTS Median follow-up was 248 days (range 105-748), and median survival time was 15.4 months. Seventeen patients had repeated PIPAC, and objective tumor response was observed in 12 (12/24 = 50 %): no vital tumor cells = 6, major pathological response = 6, minor response = 3. Postoperative adverse events > CTCAE 2 were observed in 9 patients (9/24, 37.5 %). In 3/17 patients, a later PIPAC could not be performed due to non-access. Two patients (ECOG 3 and 4) died in the hospital due to disease progression. CONCLUSION PIPAC with low-dose cisplatin and doxorubicin was safe and induced objective tumor regression in selected patients with PM from recurrent, platinum-resistant GC. First survival data are encouraging and justify further clinical studies in this indication.

Abstract
BACKGROUND Quality of Life (QoL) plays an important role in patients with peritoneal metastasis and is deteriorating continuously until death. Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) is an innovative palliative treatment of peritoneal metastasis. We present the first QoL results under PIPAC therapy. METHODS Retrospective analysis of QLQ30 questionnaire results during repeated courses of PIPAC applications in palliative patients with pretreated peritoneal metastasis. RESULTS 91 patients (M:F = 40:51, median age 64 (34-77) years) with 158 PIPAC applications were analyzed. 86% patients had previously received systemic chemotherapy. Peritoneal metastasis was advanced (Peritoneal Carcinomatosis Index I = 16 ± 10). At admission, only moderate impairment of functioning (62-83%) and symptom scores (17-47%) was observed. 48 patients received at least 2 PIPAC every 6 weeks. After PIPAC # 1, the global physical score deteriorated slightly (from 82% to 75%), but improved after PIPAC # 2 (up to 89%). Gastrointestinal symptoms (nausea/vomiting, constipation, diarrhoea, anorexia) remained stable under PIPAC therapy. CONCLUSIONS Quality of life was relatively high in this group of patients with advanced, pretreated peritoneal metastasis, explaining their wish for further therapy. Functioning scores and disease-related symptoms were not altered for at least 3 months in the patients able to receive repeated PIPAC. Except for a transient moderate increase of pain scores, PIPAC did not cause therapy-related QoL deterioration, especially no gastrointestinal symptoms.

Abstract
BACKGROUND Octogenarians with ovarian cancer limited to the abdomen may not be willing or able to undergo systemic chemotherapy. Low-dose pressurized intraperitoneal aerosol chemotherapy (PIPAC) with cisplatin and doxorubicin is a form of intra-abdominal chemotherapy which can be applied repeatedly and potentially prevents from the systemic side-effects of chemotherapy. CASE REPORT We present the case of an 84-year-old woman with laparoscopically and histologically confirmed ovarian cancer who refused to undergo systemic chemotherapy. She was treated with eight courses q 28-104 days of low-dose PIPAC with cisplatin at 7.5 mg/m(2) and doxorubicin at 1.5 mg/m(2) at 12 mmHg and 37 °C for 30 min. Objective tumor response was noted, defined as tumor regression on histology, and stable disease noted by peritoneal carcinomatosis index on repeated video-laparoscopy and abdominal computed tomographic scan. The treatment was well-tolerated with no Common Terminology Criteria for Adverse Events (CTCAE) CTCAE >2. With a follow-up of 15 months, the patient is alive and clinically stable. The quality of life measured by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 demonstrated improvement over 5-6 months (global physical score, global health score, global quality of live) without cumulative increase of gastrointestinal toxicity. CONCLUSION Low-dose PIPAC is a new form of intraperitoneal chemotherapy which may be applied repeatedly in octogenarian patients. PIPAC may be an alternative and well-tolerated treatment for selected octogenarian patients with ovarian cancer limited to the abdomen who cannot be treated with systemic chemotherapy.

Abstract
BACKGROUND Melanoma of the breast is a rare disease and may present as a metastatic manifestation of primary cutaneous melanoma or as primary malignant melanoma of the breast (PMMB). Clinical presentations of PMMB vary and surgery is the mainstay of treatment. CASE REPORT We present the case of a 54-year-old woman with a primary malignant melanoma of the left breast. She was treated with mastectomy, axillary sentinel lymph node excision and primary reconstruction with a tissue expander. Final histology revealed a malignant melanoma with 10 cm in the largest diameter. Molecular characterization by DNA-sequencing showed B-RAF, N-RAS and c-kit wild types. Immunohistochemical characterization demonstrated weak expression of S100 and melan-A and strong expression of polyclonal S100. HMB45, tyrosine kinase and the cytokeratins AE1/AE3 and MNF 116 were not expressed. Lymphoma-specific markers (CD30, CD3, CD20) and sarcoma-specific markers (desmin, actin, CD34) were also negative. The tumor proliferation rate according to Mib1-staining was 90%. Staging of the abdomen, chest, head and bones showed no evidence of metastases. A dermatological examination showed no primary melanoma of the skin. Interferon-alpha was suggested as adjuvant therapy but declined by the patient. With a follow-up of 6 months, the patient is still alive with no evidence of disease. CONCLUSION PMMB is rare and may be successfully treated with surgical excision. Locally advanced PMMB may occur without regional and distant metastases.

Abstract
OBJECTIVE The objective of this study was to provide an overview of published and ongoing trials of pressurized intraperitoneal chemotherapy (PIPAC) in ovarian cancer. DESIGN The study comprised a systematic literature review. RESULTS We identified 10 studies, including 2 ex vivo and in vitro studies, 6 clinical studies, and 2 ongoing clinical trials using PIPAC in women with recurrent ovarian cancer and pseudomyxoma peritonei. Experimental evidence and clinical study data demonstrate that PIPAC increases peritoneal cavity coverage and depth of peritoneal infiltration, and is technically feasible. Occupational safety has been established. PIPAC has demonstrated antitumor activity based on histological, radiological, and clinical evidence. The toxicity of PIPAC is manageable and restricted to Common Terminology Criteria for Adverse Events grade 2-3 events when used without concomitant cytoreductive surgery. Further clinical trials assessing efficacy and dose escalation are ongoing. CONCLUSIONS PIPAC is technically feasible, has a safe local and systemic safety profile, and has antitumor activity in women with peritoneal carcinomatosis from recurrent ovarian cancer.

Abstract
OBJECTIVE To assess the activity of laparoscopic Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) in women with recurrent, platinum-resistant ovarian cancer. METHODS Prospective case series using repeated courses q 28-42 days of PIPAC containing cisplatin 7.5 mg/m(2) and doxorubicin 1.5 mg/m(2) at 12 mmHg and 37°C for 30 min. Objective tumor response was defined as tumor regression on histology and peritoneal carcinomatosis index (PCI) improvement on repeated video-laparoscopy. RESULTS 34 PIPAC procedures were performed in 18 women, in 8 instances combined with cytoreductive surgery (CRS). Eight women had repeated PIPAC and objective tumor response was observed in 6 (complete remission: 1; partial remission: 2; stable disease: 3). Five adverse events WHO grade ≥ 2 were noted, 3 of them after combined CRS. No perioperative mortality occurred. Median follow-up was 192 days (min. 13-max. 639). Cumulative survival after 400 days was 62% and mean actuarial survival time was 442 days. In a multivariable regression analysis with objective tumor response (yes vs. no) as the dependent variable and PIPAC (1 vs.>1), patient age (<75 vs.≥75 years), serum CA-125 (<1000 vs.>1000 U/mL), and the presence of ascites (yes vs. no) as independent variables, PIPAC independently predicted objective tumor response. CONCLUSION PIPAC has activity in women with recurrent, platinum-resistant ovarian cancer and should be investigated in prospective clinical trials.

Abstract
Background Peritoneal carcinomatosis (PC) is an unmet medical need. Despite recent improvements, systemic chemotherapy has limited efficacy. We report the first application of intraperitoneal chemotherapy as a pressurized aerosol in human patients.
Methods Three end-stage patients with advanced PC from gastric, appendiceal, and ovarian origin were treated as a compassionate therapy. All patients had received previous systemic chemotherapy. A pressurized aerosol of CO2 loaded with doxorubicin 1.5 mg/m2 and cisplatin 7.5 mg/m2 (pressurized intraperitoneal aerosol chemotherapy, PIPAC) was applied into the abdomen for 30 min at a pressure of 12 mmHg and a temperature of 37 °C. Results No side-effects >2 CTCAE were observed, and the procedures were well tolerated. Early hospital discharge was possible (days 2–5). Nuclear presence of doxorubicin was documented throughout the peritoneum, reaching high local concentration (≤4.1 μmol/g) and plasma concentration was low (4.0–6.2 ng/ml). PIPAC created no significant adhesions, could be repeated, and was applied 6×, 4×, and 2×. Two patients showed a complete and one a partial histological remission. Mean survival after the first PIPAC was 288 days. One patient is alive after 567 days. Conclusions PIPAC shows superior pharmacological properties with high local concentration and low systemic exposure. PIPAC can induce regression of PC in chemoresistant tumors, using 10 % of a usual systemic dose.

Abstract
Background Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel approach for treating peritoneal carcinomatosis. First encouraging results have been obtained in human patients. However, delivering chemotherapy as an aerosol might result in an increased risk of exposure to health care workers, as compared with other administration routes. Methods PIPAC was applied in two human patients using chemotherapeutic drugs (doxorubicin and cisplatin), and air contamination levels were measured under real clinical conditions. Air was collected on a cellulose nitrate filter with a flow of 22.5 m3/h. To exclude any risk for health care workers, both procedures were remote controlled. Toxicological research of cisplatin was performed according to NIOSH 7300 protocol. Sampling and analysis were performed by an independent certification organization. Results The following safety measures were implemented: closed abdomen, laminar airflow, controlled aerosol waste, and protection curtain. No cisplatin was detected in the air (detection limit < 0.000009 mg/m3) at the working positions of the surgeon and the anesthesiologist under real PIPAC conditions. Conclusions For the drugs tested, PIPAC is in compliance with European Community working safety law and regulations. Workplace contamination remains below the tolerance margin. The safety measures and conditions as defined above are sufficient. Further protecting devices, such as particulate (air purifying) masks, are not necessary. PIPAC can be used safely in the clinical setting if the conditions specified above are met. However, a toxicological workplace analysis must be performed to confirm that the procedure as implemented complies with local regulations.

Abstract
e16523 Background: Peritoneal carcinomatosis (PC) is common in ovarian (OC) and other gynaecological cancers. We have developed an innovative therapy, Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC), which improves local tumor drug uptake and can be combined with systemic chemotherapy. PIPAC achieves outstanding local biodisponibility with low systemic exposure. Liver and renal toxicity are minimal. The procedure is safe for health workers. We present first results obtained in end-stage PC from gynaecological origin. Methods: Since 1.12.2011 we have performed 18 PIPAC applications in 9 end-stage PC patients with OC (n = 4), papillary (n = 3), tuba (n = 1) and cervix (n = 1) cancer. Mean age was 64.6 ± 16 years. In 4 instances, PIPAC was combined with cytoreductive surgery. Patients were followed-up until Dec, 2012 or until death. Tumor response was assessed by macroscopy (PCI) and microscopy. Results: No intraoperative complication was noted. Mean operating time (PIPAC alone) was 97 ± 20 min. PIPAC could be repeated at 6-weeks intervals (4x: n = 1; 3x: n = 3: 1x: n = 5). In one case, adhesions prevented iterative PIPAC. No adverse event > 2 CTCAE was noted after PIPAC alone. Six patients are alive. Median survival has not been reached after a mean follow-up of 8 months, actuarial survival after one year is 58,3%. Four patients were eligible for response assessment after repeated PIPAC. One showed complete remission (CR), three partial remission (PR). Performance index (Karnofsky) increased from 62 ± 17 % to 82 ± 5 % after therapy. Conclusions: These first results are promising. PIPAC can induce a regression of PC in advanced, therapy-resistant gynaecological cancers. PIPAC is well tolerated and can improve patient’s performance. First survival data are encouraging. PIPAC will now be evaluated in a phase-II clinical trial with cisplatin and doxorubicine (EudraCT 2012-004397-26) in therapy-resistant, recurrent OC.

Abstract
Background Both in animal models and in human patients, pressurized intraperitoneal aerosol chemotherapy (PIPAC) has been shown to improve local bioavailability of chemotherapy in peritoneal nodules, as compared with conventional peritoneal lavage. Pharmacokinetic studies show a low drug concentration in peripheral venous blood. However, hepatic and renal toxicities induced by delivering chemotherapeutic drugs into the abdomen as a pressurized aerosol have not yet been investigated. Methods Liver and renal function as well as toxicity parameters were monitored after eight PIPAC applications with doxorubicin (1.5 mg/m2 body surface) and cisplatin (7.5 mg/m2 body surface) in three end-stage patients suffering therapy-resistant peritoneal carcinomatosis. PIPAC was repeated at 4-week intervals (three times in two patients, twice in one patient). Peripheral venous blood was collected preoperatively and then daily until the 5th postoperative day, and sent to the hospital’s clinical chemistry laboratory. Statistical analysis was performed by analysis of variance (ANOVA). Results Gamma-glutamyltransferase was significantly elevated (p < 0.05) in the early postoperative phase. Glutamic oxaloacetic transaminase [aspartate aminotransferase], glutamic pyruvic transaminase [alanine aminotransferase], and bilirubin levels were not influenced by the procedure. Quick-test remained normal. Serum creatinine levels were not altered. Conclusions Under the above conditions, PIPAC did not induce clinically relevant liver cytotoxicity. Liver metabolism and function were not altered. Renal function remained within the normal range. No cumulative toxicity was observed after repeated PIPAC. PIPAC appears to be associated with very limited hepatic and renal toxicity, which might be a significant advantage over other administration routes.

Abstract
The treatment of advanced rectal cancer is a complicated task that can only poorly be reduced to the simple question "to operate or not to operate?" Instead the following factors must be taken into consideration: symptomatic versus non-symptomatic patients, emergency surgery versus elective surgery, proximal versus distal rectal cancer, local advanced versus metastatic disease, primary tumour versus recurrence, unresectable versus potentially resectable metastases, resection versus diversionary surgical procedures, etc. Also within the conservative group one must decide between interventional therapy (combined chemotherapy, stent placement, radiotherapy, etc.) and purely palliative therapy. Results from studies are not sufficient for the formulation of general recommendations. However, there are only few arguments against a surgical procedure in a symptomatic situation when the primary tumour dominates. In cases of metastasizing colorectal cancer modern chemotherapeutic procedures and new antibody therapies can markedly prolong survival. These results cannot be achieved by surgery alone. In this situation, it should be considered whether the longer life expectancy will be accompanied by the later occurrence of symptoms, which again justifies a surgical indication within the framework of multimodality therapy. The widely differing starting situations lead to different therapeutic approaches so that an individual indication can be made in the course of a tumour board discussion.
