Pancreatic cancer is a lethal disease with increasing incidence. Most patients present with advanced disease, for which palliative systemic chemotherapy is the only therapeutic option. Despite improved median survival rates with FOLFIRINOX or gemcitabine chemotherapy compared to the best supportive care, many individual patients may not benefit from chemotherapy. Biomarkers are needed to predict who will benefit from chemotherapy and to monitor a patient’s response to chemotherapy. This review summarizes current research and future perspectives on circulating biomarkers for systemic chemotherapy response.

The optimum treatment of nonresectable low-grade gliomas of childhood remains undecided. There has been increased interest in the use of chemotherapy for young children, but little information concerning the long-term efficacy of such treatment. Seventy-eight children with a mean age of 3 years (range 3 months-16 years) who had newly diagnosed, progressive low-grade gliomas were treated with combined carboplatin and vincristine chemotherapy. The patients were followed for a median of 30 months from diagnosis, with 31 patients followed for more than 3 years. Fifty-eight children had diencephalic tumors, 12 had brainstem gliomas, and three had diffuse leptomeningeal gliomas. Forty-four (56%) of 78 patients showed an objective response to treatment. Progression-free survival rates were 75 ± 6% at 2 years and 68 ± 7% at 3 years. There was no statistical difference in progression-free survival rates between children with neurofibromatosis Type 1 and those without the disease (2-year, progression-free survival 79 ± 11% vs. 75 ± 6%, respectively). The histological subtype of the tumor, its location, and its maximum response to chemotherapy did not have an impact on the duration of disease control. The only significant prognostic factor was age: children 5 years old or younger at the time of treatment had a 3-year progression-free survival rate of 74 ± 7% compared with a rate of 39 ± 21% in older children (p < 0.01). Treatment with carboplatin and vincristine is effective, especially in younger children, in controlling newly diagnosed progressive low-grade gliomas.

Response rates to cytotoxics in gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs) vary; recent trials demonstrated lack of objective response rates in up to 70% of patients. Identification of predictive therapeutic biomarkers would be beneficial in the treatment of GEP. Selected markers with known or suspected capability of predicting response to cytotoxics or prognosis (Ki-67, p53, multidrug resistance protein-1 (MDR1), Akt, thymidylate synthase (TS), phosphatase and tensin homolog (PTEN), CA9, cluster of differentiation 34 (CD34), vascular endothelial growth factor (VEGF), hypoxia-inducible factor (HIF)-1, mismatch repair gene – human mutL homolog 1 (hLMH1), and Bcl-2) were analyzed using immunohistochemisrtry in 60 treatment-naive patients receiving chemotherapy (n=46) or chemoembolization (n=14) for inoperable advanced and/or metastatic GEP and correlated with prognosis (survival and response rates). Therapy included systemic chemotherapy with streptozotocin (n=28), doxorubicin (n=14), 5-fluorouracil (n=18), and etoposide/cisplatinum (n=16), or chemoembolization (streptozotocin, 9; doxorubicin, 5). Factors associated with overall survival in the entire cohort were Ki-67, P<0.001; tumor grade, P<0.001; tumor differentiation, P<0.001; CA9, P=0.004; Akt, P=0.01; HIF-1, P<0.001; p53, P<0.0001; and hMLH1, P=0.005. Markers associated with treatment response included overall group: Akt and PTEN (P=0.05 and 0.05 respectively); streptozotocin: Akt (P=0.07), TS (P=0.02), and PTEN (P=0.017); doxorubicin: Ki-67 (P=0.05), Akt (P=0.06), and CA9 (P=0.02). At multivariate analysis, Akt was significantly associated with a nonresponse to therapy (objective response (OR): 0.2 (0.05–0.8)). For patients receiving only systemic chemotherapy (n=46), PTEN (0.04) and hLMH1 (0.03) were correlated with treatment response and for individual molecules were streptozotocin: PTEN (P=0.008) and hLMH1 (0.07); doxorubicin: Akt (P=0.09), CA9 (P=0.09), and hLMH1 (P=0.09). These results demonstrate a number of new prognostic biomarkers in GEP-NET, and in addition, response to chemotherapy was correlated with a simple panel of selected markers (such as CA9, Akt, PTEN, TS, and hLMH1).

e14685 Background: Treatment with single agent gemcitabine provides modest benefits in patients with metastatic pancreatic cancer.This study was performed to determine the efficacy of gemcitabine in combination with oxaliplatin and capecitabine in patient with recurrent or metastatic pancreatic adenocarcinoma. Methods: This was a prospective, single-arm, single center study in patients with chemotherapy-naive metastatic or recurrent pancreatic adenocarcinoma. The primary endpoint was objective response. The study was designed as a Simons two-stage optimal design and was divided into two stages. The first stage was to recruit up to 18 patients. If at least two objective responses were obtained, then a further 25 patients would be enrolled into the study. If no more than two responses were obtained among these 18 patients, the study would be halted. The study patients received gemcitabine 800 mg/m2 on day1, plus oxaliplatin 100 mg/m2 on day 1 and capecitabine 800 mg/m2/day on days 1-7 every 14 days. Treatment was to be administered until disease progression or until withdrawal from the study due to unacceptable toxicity or other reasons. Results: Eighteen patients were enrolled. Median age was 63 years (range, 39-73 years). Among these 18 patients, only one patient (5.5%) achieved an objective response. Therefore, the accrual terminated. The median time to disease progression was 2.1 months, and the median overall survival duration was 4.9 months. One-year overall survival rates were 35.3%. The most frequently reported grade 3 or 4 adverse events were asthenia (16.6%), and nausea (5.5%). There were no unexpected toxicities. Conclusions: The addition of oxaliplatin and capecitabine to gemcitabine did not improve objective response in the first-line treatment of advanced pancreatic cancer patients.

AbstractOne hundred and thirty-nine patients with advanced head and neck cancer were treated with a combination of vincristine, bleomycin, methotrexate with a folinic acid rescue, 5-fluorouracil and hydrocortisone given over 24 hours, as initial therapy on days one and 14 prior to conventional local therapy on day 28. One hundred and thirty-six patients were assessed for chemotherapy response on day 28. Ninety-one patients (67 per cent) had an objective response and 45 (33 per cent) were classed as non-responders, although 13 had a minimal (20–30 per cent) response. The complete remission rate following local therapy was significantly greater in chemotherapy responders (76 per cent) than in non-responders (54 per cent) p<0.05. Toxicity was minimal, provided standard medical precautions were observed, and 87 patients (63 per cent) reported no side-effects. There was 100 per cent patient compliance. Sex or histological grade did not significantly influence response to chemotherapy. Oral cavity or nasopharyngeal tumours responded better than other sites (p<0.05). Patients under 49 were more likely to respond to chemotherapy than older patients (p<0.01). Survival data are available for a mean follow-up time of 48 months (range 12–78 months). Chemotherapy responders have a longermedian survival than non-responders, 33 versus 20 months (p<0.05). Patients who achieve a complete remission after local therapy live significantly longer than those with residual disease, median durations of survival being 52.4 and 7.8 months respectively (p<0.001). Actuarial analyses indicate that at five years 46 percent of patients in complete remission are alive, compared with only 9 per cent with residual disease. Since chemotherapy responders are significantly more likely to achieve a complete remission than non-responders (p<0.05), objective response to this schedule of chemotherapy is a good prognostic sign.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is an innovative approach for treating peritoneal carcinomatosis that applies chemotherapeutic drugs into the peritoneal cavity as an under-pressure airflow. It improves local bioavailability of cytostatic drugs as compared to conventional intraperitoneal chemotherapy. The aim of this study is to prove feasibility, efficacy and safety of this new treatment. Patients included in the analysis underwent at least two single port PIPAC procedures; drugs used were Oxaliplatin for colorectal cancers and Cisplatin + Doxorubicin for ovarian, gastric, and primary peritoneal cancers. The primary endpoint was the Disease Control Rate according to the RECIST (Response Evaluation Criteria in Solid Tumors) criteria. Secondary significant endpoints were overall and progression free survival, tumor regression on histology, and quality of life. Safety and tolerability were assessed according to the Common Terminology Criteria for Adverse Events 4. Sixty-three patients were enrolled in this trial. Forty patients (100 PIPAC) were eligible for analysis. Twenty patients were undergoing systemic chemotherapy. Fourteen patients reported an objective response (35%). Median overall survival was 18.1 months; median progression-free survival was 7.4 months. Minor morbidity was observed in seven procedures. Grade 3 complications occurred in two patients, and grade 4 in one patient submitted to reoperation. Single-port PIPAC is feasible, safe, and easy to perform. The combined treatment based on systemic chemotherapy and PIPAC does not induce significant hepatic and renal toxicity and can be considered a valid therapeutic option in patients with advanced peritoneal disease. Further studies on the use of PIPAC alone, possibly with different drug dosages, may define the real effectiveness of the procedure.

Background: pancreatic cancer (PC) has increasing incidence and mortality in developing countries, and drug resistance is a significant hindrance to the efficacy of successful treatment. The objective of this systematic review and meta-analysis was to evaluate the association between miRNAs and response to chemotherapy in pancreatic cancer patients. Methods: the systematic review and meta-analysis was based on articles collected from a thorough search of PubMed and Science Direct databases for publications spanning from January 2008 to December 2018. The articles were screened via a set of inclusion and exclusion criteria based on the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. Data was extracted, collated and tabulated in MS Excel for further synthesis. Hazard ratio (HR) was selected as the effect size metric to be pooled across studies for the meta-analysis, with the random effects model being applied. Subgroup analysis was also conducted, and the presence of publication bias in the selected studies was assessed. Publication bias of the included studies was quantified. Findings: of the 169 articles screened, 43 studies were included in our systematic review and 13 articles were included in the meta-analysis. Gemcitabine was observed to be the principal drug used in a majority of the studies. A total of 48 miRNAs have been studied, and 18 were observed to have possible contributions to chemoresistance, while 15 were observed to have possible contributions to chemosensitivity. 41 drug-related genetic pathways have been identified, through which the highlighted miRNA may be affecting chemosensitivity/resistance. The pooled HR value for overall survival was 1.603; (95% Confidence Interval (CI) 1.2–2.143; p-value: 0.01), with the subgroup analysis for miR-21 showing HR for resistance of 2.061; 95% CI 1.195–3.556; p-value: 0.09. Interpretation: our results highlight multiple miRNAs that have possible associations with modulation of chemotherapy response in pancreatic cancer patients. Further studies are needed to discover the molecular mechanisms underlying these associations before they can be suggested for use as biomarkers of response to chemotherapeutic interventions in pancreatic cancer.

AimTo evaluate the efficacy of hepatic artery infusion (HAI) of floxuridine (FUDR) in combination with systemic chemotherapy in patients with pancreatic cancer liver metastases (PCLM).Patients and MethodsWe retrospectively collected clinical data of 347 patients with PCLM who underwent first-line chemotherapy at two Chinese centers between 2012 and 2019. Propensity score matching between patients with and without HAI was performed to compensate for differences in baseline characteristics. Objective response rate (ORR) and overall survival (OS) between groups were compared. HAI pump functionality was recorded.ResultsData of 258 patients (62 patients with HAI and 196 patients without HAI) were used for matching. After 1:1 ratio matching, 62 patients per group were included. The intrahepatic ORR was 66.1% in the HAI group and 22.6% in the non-HAI group (P &lt; 0.001), and the extrahepatic ORR was 25.0 versus 28.9% (P = 0.679). The median OS was significantly longer in HAI group (14.0 versus 10.8 months, P = 0.001). Multivariance COX regression showed HAI led to a decrease in hazard ratio for death by 61.8% (HR = 0.382; 95% CI: 0.252–0.578; P&lt; 0.001). Subgroup analysis revealed that patients without EHM, with higher intrahepatic tumor burden and with synchronous liver metastasis benefited more from HAI. Dysfunction of HAI pump occurred in 5.7% of patients during the period of follow-up.ConclusionsIn patients with PCLM, first-line treatment with HAI FUDR plus SCT resulted in higher intrahepatic response and better OS.

TPS10124 Background: Nab-paclitaxel/gemcitabine ( nab-P/gem) is an effective 1st line regimen for metastatic pancreatic ductal adenocarcinoma (mPDAC). Elderly mPDAC patients (pts) may as well benefit from nab-P/gem. Geriatric assessments to evaluate the functional reserve of these pts may allow individualization of treatment. Therefore, the aim of this study is to determine whether comprehensive geriatric assessments (CGAs) can predict the benefit from combined nab-P/gem therapy for elderly mPDAC pts in 1st line. A stratified treatment approach shall result in patient groups with a stable or improving CGA performance during the 1st cycle of treatment. Methods: GrantPax (NCT02812992) is a multicenter, open label phase 4 interventional trial with stratified parallel treatment groups (n = 45 per arm). The hypothesis is that individualized assessment directed treatment algorithms identify elderly pts (≥70 yrs), who benefit from combined nab-P/gem therapy. The study uses a CGA to stratify pts as GOGO, SLOWGO or FRAIL. Depending on test outcome, pts receive chemotherapy (GOGO: nab-P/gem; SLOWGO: gem mono) or best supportive care (FRAIL). After 1st cycle of chemotherapy (4 wks) a CGA and safety assessment will be performed to assign pts to their definite treatment arm. The primary objective is that CGA-stratified pts do not decline in their CGA performance in response to chemotherapy, measured as a loss of 5 points or less in Barthels activities of daily living (ADL1 vs. ADL2 during CGA core assessment). The expected proportion of pts with ADL decline in each treatment group is 6%. Under this assumption it shall be shown with 80% power at one-sided significance level alpha of 0.05 that the proportion of pts with functional decline is less than 20% (n = 43 per group; ADL decline: n = 2 per group). Secondary endpoints are CGA scores during the course of therapy (CGA1-4), response rates, safety, survival rates, duration of treatment, cumulative dose, quality of life and discrepancy between CGA strata estimation by the investigator and true CGA assessment. GrantPax is the first trial realizing a CGA-driven treatment to individualize cancer therapy for elderly pts. Clinical trial information: NCT02812992.
