Patients with stage IV of pancreatic cancer were locally irradiated by 51 Gy total dose (fraction dose was 3 Gy). Gemcytabin, gemsar + carboplatin, or carboplatin + etoposid + 5-fluorouracil were intraarterially administered as chemotherapy preparations. DNA radiosensitivity biomarkers in patient blood were determined before the treatment start. There was revealed interrelation between value of biochemical index and life span patient. The DNA blood radiosensitivity index determinations are enabled to predict personally the results more success treatment in patients with pancreatic cancer after the use of abovementioned regimens of chemoradiotherapy.

Pancreatic ductal adenocarcinoma (PDAC) exhibits the poorest prognosis of all solid tumors, with a 5-year survival of less than 10%. To improve the prognosis, it is necessary to advance in the development of tools that help us in the early diagnosis, treatment selection, disease monitoring, evaluation of the response and prognosis. Liquid biopsy (LB), in its different modalities, represents a particularly interesting tool for these purposes, since it is a minimally invasive and risk-free procedure that can detect both the presence of genetic material from the tumor and circulating tumor cells (CTCs) in the blood and therefore distantly reflect the global status of the disease. In this work we review the current status of the main LB modalities (ctDNA, exosomes, CTCs and cfRNAs) for detecting and monitoring PDAC.

Morbidity and mortality from pancreatic cancer is an urgent medical and social problem. Evaluation of statistical indicators in dynamics makes it possible to identify organizational and clinical problems in providing care to patients with malignant neoplasms of the pancreas. Medical and statistical indicators of incidence of malignant pancreatic neoplasms in St. Petersburg residents are evaluated. The assessment of medical and statistical indicators of the incidence of malignant neoplasms of the pancreas in residents of St. Petersburg. Statistical data were studied for the period from 2014 to 2019. The increase in the "rough" indicator of primary morbidity changed from 417.99 per 100 thousand population in 2014 to 505.6 in 2019. In the structure of primary cancer incidence, the indicator of active detection of pancreatic cancer glands in 2014 amounted to 3.6%, in 2019 3.8%. The proportion of patients with diagnoses confirmed morphologically increased from 48.9% to 61.4%. The proportion of patients with newly diagnosed stage IV of the disease changed from 39.5% in 2014 to 51.4% in 2019, and in patients with stage III in 2019 it was 33.3% (a decrease in comparison with 2014 15.3%). In 2019, the disease was diagnosed at stage II in 15.2% of patients. The proportion of patients with stage I in 2019 was 6.6%, this indicator in 2014 was registered at the level of 19.2%. From 2014 to 2019, the one-year mortality rate did not change and amounted to 67.9 and 67.4%, respectively (the decrease was 0.7%). Over the past 5 years, there has been no significant downward trend in the "rough" incidence and mortality rates from pancreatic cancer. However, in the dynamics, there was an increase in the number of patients registered for 5 or more years, and an increase in the accumulation index of the contingent of patients with pancreatic cancer.

e18530 Background: While disparities in pancreatic cancer (PC) are documented, it is unclear whether these inequities occur at the time of diagnosis or throughout treatment. We hypothesize social determinants of health (SDH) such as income, education, race and insurance status are a) associated with a late diagnosis of PC (Stage IV vs Stages 0-III) and b) associated with overall survival (OS) in Stage IV patients. Methods: The National Cancer Database 2017 version was accessed. Primary outcome: diagnosis of Stage IV PC. Secondary outcome: OS. Primary predictors: race, income, education, insurance. Confounders: Charlson comorbidity score, age, sex. Univariate and multivariate regression models evaluated the association between SDH and a late diagnosis of PC. Univariate and multivariate Cox proportional hazards model examined OS. 95% Confidence Intervals were used. Results: 230,877 patients were included. Median 68 yrs, mean 67.3 SD(12.1). In univariate analysis, education (>93% high school completion (HSC) vs <82.4%, OR 0.93 [0.91 – 0.95]), income (>$63,333 vs<$40,277, OR 0.94 [0.92– 0.96]), and insurance (Private vs No, OR 0.70 [0.66 – 0.73]), decreased the odds of Stage IV PC. Black race was associated with higher odds of Stage IV PC (vs White, OR 1.11 [1.08 – 1.14]). In multivariate analysis, education and having insurance decreased the risk of a late diagnosis, whereas black race increased it (table). In univariate Cox analysis, higher income (>$63,333 (vs<$40,277), HR 0.82 [0.81– 0.83]), insurance (Private vs No, HR 0.77 [0.73 – 0.76]) and education (>93% HSC vs <82.4%, HR 0.87 [0.86 – 0.88]) improved OS. Black race was associated with poorer OS (vs White, HR 1.03 [1.02 – 1.05]). In multivariate Cox analysis, only higher income (>$63,333 (vs<$40,277), HR 0.87 [0.85 – 0.89]) and having insurance (Private vs No, HR 0.77 [0.74 – 0.79]) were associated with improved OS. Conclusions: SDH impacted the continuum of pancreatic neoplasia care, from diagnosis to treatment. Expanding insurance coverage could be an effective public health intervention to improve early diagnosis and survival rates.[Table: see text]

<b><i>Background:</i></b> Intractable pancreatic pain is one of the most common symptoms of patients with pancreatic ductal adenocarcinoma (PDAC). Celiac neurolysis (CN) and splanchnicectomy were already described as effective methods to manage abdominal pain in unresectable PDAC, but their impact on overall survival (OS) has not yet been established. <b><i>Objective:</i></b> We aimed to investigate the impact of CN and splanchnicectomy on the survival of patients with unresectable pancreatic cancer. <b><i>Methods:</i></b> A systematic review of PubMed and Cochrane Library according to predefined searching terms was conducted in March 2020. Hazard ratios (HR) of OS data were calculated using the Mantel-Haenszel model for random effects or fixed effects. <b><i>Result:</i></b> Four randomized-controlled trials (RCTs) and 2 non-RCTs with a total of 2,507 patients were identified. The overall pooled HR did not reveal any relevant effect of CN and splanchnicectomy on OS (HR: 1.03; 95% CI: 0.81–1.32), which was also underlined by the sensitivity analysis of RCTs (HR: 1.0; 95% CI: 0.72–1.39) and non-RCTs (HR: 1.07; 95% CI: 0.71–1.63). However, subgroup analyses depending on tumor stage revealed that CN or splanchnicectomy was associated with a worsened OS in AJCC (American Joint Committee on Cancer) stage III patients with unresectable PDAC (HR: 1.22; 95% CI: 1.03–1.45), but nor for AJCC stage IV patients (HR: 1.27; 95% CI: 0.9–1.80). <b><i>Conclusion:</i></b> Although only few data are currently available, this systematic review with meta-analysis showed that in unresectable PDAC, CN or splanchnicectomy is associated with a worsened survival in stage III PDAC patients, with no effect on stage IV PDAC patients. These data call for caution in the usage of CN or splanchnicectomy in stage III PDAC and for further studies addressing this observation.

Objectives: To evaluate the role of stereotactic body radiotherapy (SBRT) as a local ablative treatment (LAT) in oligometastatic pancreatic cancer. Methods: Patients affected by histologically confirmed stage IV pancreatic adenocarcinoma were included in this analysis. Endpoints are local control (LC), progression-free survival (PFS), and overall survival (OS). Results: From 2013 to 2017, a total of 41 patients were treated with SBRT on 64 metastases. Most common sites of disease were lung (29.3%) and liver (56.1%). LC at 1 and 2 years were 88.9% (95% CI 73.2–98.6) and 73.9% (95% CI 50–87.5), respectively. Median LC was 39.9 months (95% CI 23.3—not reached). PFS rates at 1 and 2 years were 21.9% (95% CI 10.8–35.4) and 10.9% (95% CI 3.4–23.4), respectively. Median PFS was 5.4 months (95%CI 3.1–11.3). OS rates at 1 and 2 years were 79.9% (95% CI 63.7–89.4) and 46.7% (95% CI 29.6–62.2). Median OS was 23 months (95%CI 14.1–31.8). Conclusions: Our results, although based on a retrospective analysis of a small number of patients, show that patients with oligometastatic pancreatic cancer may benefit from local treatment with SBRT. Larger studies are warranted to confirm these results. Advances in knowledge: Selected patients affected by oligometastatic pancreatic adenocarcinoma can benefit from local ablative approaches, like SBRT

Pediatric renal cancer is rare, and robust evidence for treatment recommendations is lacking. In the perspective of personalized medicine, clinicians need new biomarkers to improve risk stratification and patients’ follow-up. Herein, we analyzed some liquid biopsy tools, which have been never tested in pediatric renal cancer: namely, circulating tumor cells (CTCs); the expression of M30, an apoptosis marker, to test CTC metastatic potential; and c-MET expression in CTCs, because of its role in renal cancer progression and drug-resistance. Furthermore, we evaluated the Circulating Endothelial Cells (CECs), whose utility we previously demonstrated in adult metastatic renal cancer treated with anti-angiogenic therapy. We compared two renal cell carcinomas of clear-cell type, stage I and IV, which underwent surgery and surgery plus Sunitinib, respectively. Baseline CTC level and its changes during follow-up were consistent with patients’ outcome. In case 2, stage IV, the analysis of CECs performed during Sunitinib revealed a late response to treatment consistent with poor outcome, as the finding of M30-negative, viable cells. Noteworthily, few CTCs were MET-positive in both cases. Our study highlights the feasibility for a change in the prognostic approach and follow-up of childhood renal cancer, with a view to guide a better treatment design.

Abstract Background Liquid biopsies of blood plasma cell free DNA can be used to monitor treatment response and potentially detect mutations that are present in resistant clones in metastatic cancer patients. Case presentation In our non-interventional liquid biopsy study, a male patient in his fifties diagnosed with stage IV colorectal cancer and polytope liver metastases rapidly progressed after completing chemotherapy and deceased 8 months after diagnosis. Retrospective cell free DNA testing showed that the APC/TP53/KRAS major clone responded quickly after 3 cycles of FOLFIRI + Bevacizumab. Retrospective exome sequencing of pre-chemotherapy and post-chemotherapy tissue samples including metastases confirmed that the APC/TP53/KRAS and other major clonal mutations (GPR50, SLC5A, ZIC3, SF3A1 and others) were present in all samples. After the last chemotherapy cycle, CT imaging, CEA and CA19–9 markers validated the cfDNA findings of treatment response. However, 5 weeks later, the tumour had rapidly progressed. Conclusion As FOLFIRI+Bevacizumab has recently also been associated with sustained complete remission in a APC/TP53/KRAS triple-mutated patient, these driver genes should be tested and monitored in a more in-depth manner in future patients. Patients with metastatic disease should be monitored more closely during and after chemotherapy, ideally using cfDNA.
