CCL3 predicts exceptional response to TGFβ inhibition in basal-like pancreatic cancer enriched in LIF-producing macrophages.

The TGFβ receptor inhibitor galunisertib showed promising efficacy in patients with pancreatic ductal adenocarcinoma (PDAC) in the phase 2 H9H-MC-JBAJ study. Identifying biomarkers for this treatment remains essential. Baseline plasma levels of chemokine CCL3 were integrated with clinical outcomes in PDAC patients treated with galunisertib plus gemcitabine (n = 104) or placebo plus gemcitabine (n = 52).

Integration of liposomal irinotecan in the first-line treatment of metastatic pancreatic cancer: try to do not think about the white bear.

The approval of novel therapeutic agents remains widely reliant on evidence derived from large phase III randomized controlled trials. Liposomal irinotecan (ONIVYDE) stands out as the only drug that has demonstrated improved survival both as a first-line therapy in combination with oxaliplatin and 5-fluorouracil/leucovorin (5FU/LV) (NALIRIFOX) compared to the standard gemcitabine plus nab-paclitaxel in the NAPOLI3 trial, and as a second-line treatment in combination with 5FU/LV compared to the standard 5FU/LV in the NAPOLI1 trial. However, just as the white bear of the Dostoevsky's paradox, the judgment of these results is invariably distracted by the intrusive thought of how different they might be if compared to similar regimens containing standard-free irinotecan as FOLFIRINOX or FOLFIRI, respectively.

Perioperative NALIRIFOX in patients with resectable pancreatic ductal adenocarcinoma: The open-label, multicenter, phase II nITRO trial.

Background: Upfront surgery followed by postoperative treatment is a commonly adopted treatment for resectable pancreatic ductal adenocarcinoma (rPDAC). However, the risk of positive surgical margins, the poor recovery that often impairs postoperative treatments, and the risk of recurrence might limit the outcome of this strategy. This study evaluated the safety and the activity of liposomal irinotecan 50 mg/m + 5-fluorouracil 2400 mg/m + leucovorin 400 mg/m + oxaliplatin 60 mg/m (NALIRIFOX) in the perioperative treatment of patients with rPDAC.

YAP Activation Is Associated with a Worse Prognosis of Poorly Cohesive Gastric Cancer.

Poorly cohesive (PC) gastric cancer (GC) is extremely aggressive in progression, and there is an urgent need to identify the molecular pathways involved. We hypothesized the essential role of the RhoA-YAP axis in these mechanisms. The present observational multicenter retrospective study included 133 patients with PC GC treated at two dedicated European surgical centers between 2004 and 2014.

Autotaxin Secretion Is a Stromal Mechanism of Adaptive Resistance to TGFβ Inhibition in Pancreatic Ductal Adenocarcinoma.

Unlabelled: The TGFβ receptor inhibitor galunisertib demonstrated efficacy in patients with pancreatic ductal adenocarcinoma (PDAC) in the randomized phase II H9H-MC-JBAJ study, which compared galunisertib plus the chemotherapeutic agent gemcitabine with gemcitabine alone. However, additional stromal paracrine signals might confer adaptive resistance that limits the efficacy of this therapeutic strategy. Here, we found that autotaxin, a secreted enzyme that promotes inflammation and fibrosis by generating lysophosphatidic acid (LPA), mediates adaptive resistance to TGFβ receptor inhibition.

Predictive Biomarkers for a Personalized Approach in Resectable Pancreatic Cancer.

The mainstay treatment for patients with immediate resectable pancreatic cancer remains upfront surgery, which represents the only potentially curative strategy. Nevertheless, the majority of patients surgically resected for pancreatic cancer experiences disease relapse, even when a combination adjuvant therapy is offered. Therefore, aiming at improving disease free survival and overall survival of these patients, there is an increasing interest in evaluating the activity and efficacy of neoadjuvant and perioperative treatments.

Combination of peripheral neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio is predictive of pathological complete response after neoadjuvant chemotherapy in breast cancer patients.

The immune system seems to play a fundamental role in breast cancer responsiveness to chemotherapy. We investigated two peripheral indicators of immunity/inflammation, i.e.
