Background: Pancreatic cancer (PC) is one of the most lethal malignancies worldwide. This study evaluated the prognostic role of serum alanine phosphatase (ALP) and gamma-glutamyl-transferase (GGT) in metastatic PC patients. Materials & methods: 153 patients with metastatic PC receiving first-line treatment with nab-paclitaxel/gemcitabine were retrospectively enrolled in a multicenter study and stratified according to ALP (≤ or >260 U/l) and GGT (≤ or >45.5 U/l) levels. Results: Improved overall survival was recorded in patients with GGT levels ≤45.5 U/l (p

Neutropenia is a common side effect associated with nab-paclitaxel gemcitabine (Nab-Gem) therapy. We retrospectively investigated the association between neutropenia induced by first-line Nab-Gem and survival in metastatic pancreatic carcinoma patients. Metastatic pancreatic patients treated with first-line Nab-Gem were included in this retrospective analysis. Neutropenia was categorized using the National Cancer Institute Common Toxicity Criteria scale. Outcome measures were overall survival (OS), progression-free survival (PFS) and response rate. 115 patients were analyzed. Median PFS was 7 months (95% CI 5–8) for patients with grade ≥ 3 neutropenia and 6 months (95% CI 5–6) for patients with grade

Background Several progresses have been achieved for first-line chemotherapy in metastatic pancreatic ductal adenocarcinoma (PDAC) with Gem-NabP and FOLFIRINOX extensively used as standard first line regimens. However, the best second-line chemotherapy choice after progression is still not completely defined. The aim of this study is to compare effectiveness and safety of two possible second-line therapeutic options, FOLFOX and FOLFIRI, after progression to Gem-NabP. Methods From January 2015 to December 2018, patients with metastatic PDAC, progressed to the first-line treatment with Gem-NabP, and treated with a fluoropyrimidine-based second-line chemotherapy were considered eligible for our retrospective analysis. Overall survival (OS) and progression free survival (PFS) were set as primary endpoints whereas, disease control rate (DCR) and the rate and severity of treatment-related AEs were secondary endpoints. Results Overall, 31 patients were treated with Gem-NabP in first-line regimen, 11 received second-line with FOLFOX and 20 with FOLFIRI after progression. Baseline demographic and clinic features were similar in the two groups excluding median age of 55.5 years (range: 50-73) and 68 years (range: 59-72) in FOLFIRI and FOLFOX groups, respectively (p=0.002). Median PFS was three months (95%CI: 3-4), with no significative difference between the two groups. Median OS was eight months (95%CI: 5-10) and was significantly higher in the FOLFIRI group compared with the FOLFOX group, nine months (95%CI: 7-17) vs five months (95%CI: 2-10; p

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent adverse events observed with taxane use, whose disability often required modification or treatment discontinuation. The aim of this study was to assess the value of several variables as risk factors for CIPN development. Material and Methods: Eligible patients with metastatic pancreatic cancer receiving chemotherapy with nab-paclitaxel and gemcitabine were assessed in a multicenter study. Peripheral neuropathy was categorized using the National Cancer Institute Common Toxicity Criteria scale, version 4.02, and a physical/neurological examination. Univariate and multivariate regression analyses were used to identify blood-based and clinical factors associated with CIPN. Results: Data were available from 153 patients from five Italian centers. Key risk factors of CIPN in univariate regression models included age, number of chemotherapy cycles, statin assumption, and concomitant comorbidities. However, in the multivariate analysis, only for age (OR 1.0, p < 0.01, 95% CI: 1.01–1.11) and the number of cycles (OR 1.22, p < 0.01, 95% CI: 1.09–1.36), the correlation with CIPN development has been confirmed. Conclusion: Our study confirms age and the number of chemotherapy cycles as CIPN risk factors. The identification and validation of different risk factors could be advantageous to prevent or optimize management of CIPN which outstandingly affect the patient’s quality of life.

The combination of nab-paclitaxel and gemcitabine demonstrated greater efficacy than gemcitabine alone but resulted in higher rates of chemotherapy-induced peripheral neuropathy (CINP) in patients with metastatic pancreatic cancer (mPC). We aimed to evaluate the correlation between the development of treatment-related peripheral neuropathy and the efficacy of nab-P/Gem combination in these patients. mPC patients treated with nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 as a first-line therapy were included. Treatment-related adverse events, mainly peripheral neuropathy, were categorized using the National Cancer Institute Common Toxicity Criteria scale, version 4.02. Efficacy outcomes, including overall survival (OS), progression-free survival (PSF), and disease control rate (DCR), were estimated by the Kaplan–Meier model. A total of 153 patients were analyzed, of these, 47 patients (30.7%) developed grade 1–2 neuropathy. PFS was 7 months (95% CI (6–7 months)) for patients with grade 1–2 neuropathy and 6 months (95% CI (5–6 months)) for patients without peripheral neuropathy (p = 0.42). Median OS was 13 months (95% CI (10–18 months)) and 10 months (95% CI (8–13 months)) in patients with and without peripheral neuropathy, respectively (p = 0.04). DCR was achieved by 83% of patients with grade 1–2 neuropathy and by 58% of patients without neuropathy (p = 0.03). In the multivariate analysis, grade 1–2 neuropathy was independently associated with OS (HR 0.65, 95% CI, 0.45–0.98, p = 0.03). nab-P/Gem represents an optimal first-line treatment for mPC patients. Among possible treatment-related adverse events, peripheral neuropathy is the most frequent, with different grades and incidence. Our study suggests that patients experiencing CINP may have a more favorable outcome, with a higher disease control rate and prolonged median survival compared to those without neuropathy.

The value of health care should be measured as the patient’s well-being. This demands knowledge of patient’s preference. Communication, i.e. delivering messages which can be understood + taking on board requests and priorities) is a complex exercise; even more when interacting with senior patients. It must be a primary career’s privilege to satisfy his/her patient’s requests however; we have much to improve in our interaction with senior cancer patients.

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

Poor cancer-specific outcomes in the elderly group are primarily a surgical failure. Surgeons are insufficiently trained to draw a line between fit and frail patients; this results in over-treatment of the frail patient, as well as under-treatment of the fit one. Communication skills should be improved to better understand the patient's requests. The timing of the surgical procedure is crucially important; all efforts should be put in place to optimize the patient's conditions before the surgery takes place.

Patient's frailty, attitude, life expectancy, affect the decision-making process, impacting on the following four points: 1.Disclosing the diagnosis. 2.Discussing treatment options and prognosis. 3.Tailoring treatment. 4.Assisting patients along their recovery. Setting up an open, frank, transparent and informative discussion is the key step in addressing a patient-centered treatment plan. Our recommendations are summarized in the following pages.

The extent of information to cancer patients is, in general, culture-dependent. Information mainly refers to three aspects, namely diagnosis (Dx), prognosis (Px) and treatment (Rx), but the relative contribution of each domain to the information given overall is not available. To address this issue, we e-mailed a questionnaire to 9893 members of the American Society of Clinical Oncology (ASCO) asking whether they agree that information about Dx, Px and Rx contribute differently to the information given to the cancer patient overall and, if so, to what extent, both in the adjuvant and advanced settings. 857 questionnaires were evaluable. There was no statistically significant difference between the contribution of these 3 domains in the adjuvant setting (33%, 34% and 33%, respectively). In subgroup analysis, medical oncologists and haematologists attributed a significantly higher contribution of Px information compared with other specialists (P0.05). In the advanced setting, respondents estimated a higher contribution of Px (41%) to patient information overall compared with Dx and Rx (28% and 31%, respectively; P0.05). This finding was more pronounced in North America than in Europe (P0.0001), and in Germanic-language than in Romance-language countries (P = 0.005). In conclusion, information on Dx, Px and Rx are believed to contribute differently to the information delivered to cancer patients overall, depending on the stage of disease, the cultural environment and the specialty of the physician.

Fatigue is a common complaint of patients with cancer or other physical or mental disorders. In cancer patients, the estimated prevalence of fatigue is high (about 70% to 90% in different surveys). However, despite the high prevalence and widely recognized clinical relevance of fatigue, few studies have been performed to evaluate the putative causal factors and therapeutic approaches for this condition. The paucity of studies has been mainly because of the lack of proper instruments to quantify this clinical problem. Moreover, fatigue is multifactorial, which makes evaluation of precise relationships with other medical conditions difficult. In particular, fatigue is considered the cardinal symptom of anemia. The pathogenesis of anemia-related fatigue remains unclear, but some suggest that abnormalities in energy metabolism play a role in inducing fatigue. In cancer patients, this effect may be exacerbated by the increased metabolic needs associated with tumor growth. At the clinical level, the relationship between anemia and fatigue is universally accepted. However, early studies were unable to show a clear association between fatigue and hemoglobin levels. Recently, new insights were afforded by the implementation of innovative survey instruments that assess the effects of fatigue and other (nonfatigue) symptoms of anemia on the patient's well-being and quality of life. The use of these validated instruments has shown a direct effect of hemoglobin levels on fatigue and other quality of life parameters. Thus, amelioration of anemia and fatigue should be considered a primary endpoint of antineoplastic and supportive-care treatment of cancer patients. Accordingly, the search for new simplified methods of assessment of fatigue and other anemia-related symptoms and their treatment outcomes should be strongly encouraged.

Surgical excision and/or cytoreduction currently represent the treatment of choice for most gynecological tumors, regardless of the patients’ age. A robust body of evidence supports this. Despite operative complications and mortality, long-term cancer-related survival may be significantly improved by an aggressive surgical approach in the older age group as it is for younger women.

e13514 Background: Endoxifen (EN), the main active metabolite of tamoxifen (T), reaches steady state (SS) plasma levels after about 4 months of administration. It derives principally by cytochrome CYP2D6 activity, which is highly variable among patients. In order to predict individual SS EN exposure, three different approaches were investigated. Methods: Before starting T administration, 73 breast cancer patients (median age: 59 yrs, range: 30-89) were characterized by means of: 1) a phenotyping test of CYP2D6 activity, based on the urinary metabolic ratio of dextromethorphan/dextrorphan (log transformed, LMR). 2) CYP2D6 genotyping (alleles *1, *3, *4, *5, *6, *9, *10, *41), to classify patients in 3 functional groups: Extensive (EM), Intermediate (IM) and Poor (PM) Metabolizers. After starting T treatment (20mg/day), EN plasma levels were measured after 1 month (1M EN, pre- steady state) and 4 months of therapy (SS EN). ANOVA, paired and unpaired T test and linear regressions were performed to analyze associations between LMR, CYP2D6 genotype, 1M EN and SS EN. Multivariate linear regression was used to create a predictive equation; its mean prediction and absolute errors (MPE% and MAE%) and the positive and negative predictive values (PPV% and NPV%, according to median SS EN) were calculated. Results: SS EN plasma levels varied between 2.4 and 39.2 (median: 8.7) ng/ml. LMR (median: -1.6; range: -3.1- +1.2) showed a significant linear correlation with SS EN (r=-0.59; p
