Abstract Background Peritoneal malignancies include primary and metastatic cancer of the peritoneal cavity. The most common origin for peritoneal metastasis is ovarian, gastric, and colorectal cancers. Irrespective of the origin, peritoneal metastases represent the advanced disease and are associated with poor long-term outcomes. The minimally invasive approach of pressurized intraperitoneal aerosol chemotherapy (PIPAC) allows repeated applications and objective assessment of tumor response by comparing histological samples. This study aimed to investigate the initial experience with PIPAC in the Baltic region. Methods All patients who underwent PIPAC at Vilnius University Hospital Santaros Klinikos between 2015 and 2020 were included in this retrospective study. The primary outcome of the study was overall survival (OS) in patients with peritoneal carcinomatosis treated by PIPAC. The secondary outcomes included postoperative morbidity; peritoneal carcinomatosis index (PCI) and ascites reduction after treatment by PIPAC. Results In total, 15 patients underwent 34 PIPAC procedures. PIPAC-related intraoperative and postoperative morbidity occurred in 3 (8.8%) of 34 procedures. Following PIPAC, the median PCI decreased from 8 (4; 15) to 5 (1; 16) in GC patients, although, the difference failed for significance, p = 0.581. In OC patients, PCI after PIPAC remained stable. Median overall survival after PIPAC procedure was 25 (95% CI 5–44) months. Ovarian cancer patients (22; 95% CI 12–44 months) had significantly higher OS, compared to gastric cancer patients (8; 95% CI 4–16 months), p = 0.018. Conclusions PIPAC is safe and feasible for patients with gastric and ovarian cancers peritoneal metastases.

e12024 Background: Distant spread from breast cancer is commonly found in bones, lungs, liver, and central nervous system. Metastatic involvement of peritoneum and retroperitoneum is unusual and unexpected. The aim of the study was to perform a comprehensive analysis of breast cancer patients with peritoneal metastases and to compare survivals depending on biological subtypes. Methods: 44 breast cancer pts with peritoneal metastases were detected out of a database of 2,500 breast cancer patients treated in one institution between 1995 and 2005. Clinical characteristics such as estrogen receptor and progesterone receptor as well as survivals were analized based on breast cancer subtypes. Results: Mean patient age was 54 years, 25 patients (56%) had ductal invasive carcinoma while 19 (44%) were diagnosed lobular invasive carcinoma. 30 (68%) patients had endocrine responsive tumors. A HER-2 percentage is not provided due to the lack of data before the year 2000. Median survival calculated from peritoneal metastases in histologic subgroups was as follows: Median progression free survival was 36.5 months for ductal invasive carcinoma, and 23.5 months for lobular invasive breast cancer. Median overall survival was 46 (Std 38.5) months for ductal invasive breast cancer and 32 (Std 54.5) months for lobular invasive breast cancer. Conclusions: Patients with peritoneal metastases are a heterogenous group with a different outcome. The histologic subtype seems to be an important predictive factor as lobular invasive breast cancer is associated with worsened progression free an overall survival rates. No significant financial relationships to disclose.

Abstract Background Pancreatic peritoneal carcinomatosis (PPC), with the worst median overall-survival (mOS), epitomizes the incurability of metastatic cancer. Cancer stem cells (CSCs) underpin this incurability. However, inhibitors of CSC-stemness fail to increase mOS in cancer patients despite preclinical tumor-reduction. This shortfall reinforces that preclinical efficacy should be defined by increased mOS in the presence of cancer comorbidities, CSC-heterogeneity and plasticity. The primary objectives of this study are: to test the dual endothelin-1/signal peptide receptor, DEspR, as a nodal therapeutic target in PPC, given DEspR induction in anoikis-resistant pancreatic CSCs, and to validate humanized anti-DEspR antibody, hu-6g8, as a potential therapeutic for PPC. Methods We used heterogeneous pools of CSCs selected for anoikis resistance from reprogrammed Panc1 and MiaPaCa2 tumor cells (TCs), and adherent TCs reprogrammed from CSCs (cscTCs). We used multiple anti-DEspR blocking antibodies (mAbs) with different epitopes, and a humanized anti-DEspR recombinant mAb cross-reactive in rodents and humans, to test DEspR inhibition effects. We measured DEspR-inhibition efficacy on multiple prometastatic CSC-functions in vitro, and on tumorigenesis and overall survival in a CSC-derived xenograft (CDX) nude rat model of PPC with comorbidities. Results Here we show that DEspR, a stress-survival receptor, is present on subsets of PDAC Panc1-TCs, TC-derived CSCs, and CSC-differentiated TCs (cscTCs), and that DESpR-inhibition decreases apoptosis-resistance and pro-metastatic mesenchymal functions of CSCs and cscTCs in vitro. We resolve the DNA-sequence/protein-function discordance by confirming ADAR1-RNA editing-dependent DEspR-protein expression in Panc1 and MiaPaCa2 TCs. To advance DEspR-inhibition as a nodal therapeutic approach for PPC, we developed and show improved functionality of a recombinant, humanized anti-DEspR IgG4S228P antibody, hu-6g8, over murine precursor anti-DEspR mabs. Hu-6g8 internalizes and translocates to the nucleus colocalized with cyto-nuclear shuttling galectins-1/3, and induces apoptotic cell changes. DEspR-inhibition blocks transperitoneal dissemination and progression to peritoneal carcinomatosis of heterogeneous DEspR±/CD133 ± Panc1-derived CSCs in xenografted nude rats, improving mOS without chemotherapy-like adverse effects. Lastly, we show DEspR expression in Stage II-IV primary and invasive TCs in the stroma in PDAC-patient tumor arrays. Conclusion Collectively, the data support humanized anti-DEspR hu-6g8 as a potential targeted antibody-therapeutic with promising efficacy, safety and prevalence profiles for PPC patients.

Abstract Background Systemic inflammatory responses caused by tumor cells play an important role in the occurrence and development of tumors. Most of these responses are accompanied by a decrease in muscle mass. The aim of this study was to identify biomarkers that most accurately predict prognoses in patients with non-metastatic cancer and to evaluate their clinical significance when combined with muscle markers. Methods This study retrospectively evaluated 2,797 cancer patients diagnosed with cancer at TNM stages I, II, and III. Lymphocyte-C-reactive protein ratio (LCR) in conjunction with calf circumference (CC) were used (or chosed) after evaluating the predictive value of 13 inflammatory marker combinations and five anthropometric indicators for patient outcomes using the C-index. The Kaplan-Meier method and Cox’s proportional hazards regression modeling were used to analyze the individual and combined effects of these two potential biomarkers on overall survival. Results This study enrolled 1,604 men (57.3%) and 1,193 women (42.7%) with a mean age of 58.75 years. Among the 13 inflammatory nutritional indicators, the LCR was the most accurate predictor of prognoses in patients with non-metastatic cancer. The optimal threshold for the LCR was 2,500. After multifactorial adjustment, we found that low LCR had an adverse effect on overall survival (hazard ratio [HR]: 2.50; 95% confidence interval [CI]: 2.17, 2.88; P<0.001). Low LCR combined with low CC was also shown to be an independent risk factor for poor overall survival (HR: 2.26; 95% CI: 1.80, 2.83; P<0.001). In non-metastatic cancer patients of different ages, stages, surgery history, and tumor types (for example, upper gastrointestinal cancer, colorectal cancer, lung cancer), patients with a low LCR combined with a low CC had statistically significantly reduced overall survival. Compared with LCR or CC alone, the combination of the two had greater prognostic value for patients with non-metastatic cancer. Conclusions The LCR can be implemented as a useful biomarker to predict prognoses in patients with non-metastatic cancer, its predictive value is superior to the other evaluated indicators of inflammation. CC is the best anthropometric indicator of muscle loss in patients with non-metastatic cancer. The combination of LCR and CC can better predict the prognosis of patients with non-metastatic cancer, and can provide important information for clinicians to formulate diagnosis and treatment plans.
