RESUMO

The Spanish Society of Medical Oncology (SEOM) last published clinical guidelines on venous thromboembolism (VTE) and cancer in 2019, with a partial update in 2020. In this new update to the guidelines, SEOM seeks to incorporate recent evidence, based on a critical review of the literature, to provide practical current recommendations for the prophylactic and therapeutic management of VTE in patients with cancer. Special clinical situations whose management and/or choice of currently recommended therapeutic options (low-molecular-weight heparins [LMWHs] or direct-acting oral anticoagulants [DOACs]) is controversial are included.

RESUMO

BACKGROUND: Pancreatic carcinoma is one of the tumors associated with a higher risk for thromboembolic events, with incidence rates ranging from 5% to 41% in previous retrospective series. PATIENTS AND METHODS: We conducted a retrospective study in eleven Spanish hospitals that included 666 patients diagnosed with pancreatic carcinoma (any stage) between 2008 and 2011 and treated with chemotherapy. The main objective was to evaluate the incidence of venous thromboembolic events (VTE) in this population, as well as potential risk factors for thrombosis. The impact of VTE on mortality was also assessed. RESULTS: With a median follow-up of 9.3 months, the incidence of VTE was 22.1%; 52% were diagnosed incidentally. Our study was unable to confirm the ability of the Khorana score to discriminate between patients in the intermediate or high risk category for thrombosis. The presence of VTE proved to be an independent prognostic factor associated with increased risk of death (HR 2.39, 95% CI 1.96-2.92). Symptomatic events correlated with higher mortality than asymptomatic events (HR 1.72; 95% CI, 1.21-2.45; p = 0.002), but incidental VTE, including visceral vein thrombosis (VVT), negatively affected survival compared to patients without VTE. Subjects who developed VTE within the first 3 months of diagnosis of pancreatic carcinoma had lower survival rates than those with VTE after 3 months (HR 1.92, 95% CI 1.30-2.84; p<0.001). CONCLUSIONS: Pancreatic carcinoma is associated with a high incidence of VTE, which, when present, correlates with worse survival, even when thrombosis is incidental. Early onset VTE has a particularly negative impact.

RESUMO

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) is largely unresponsive to checkpoint inhibitors. Blockade of the CXCR4/CXCL12 axis increases intratumoral trafficking of activated T cells while restraining immunosuppressive elements. This study evaluates dual blockade of CXCR4 and PD1 with chemotherapy in PDAC. PATIENTS AND METHODS: Multicenter, single-arm, phase II study to evaluate the safety and efficacy of motixafortide and pembrolizumab combined with chemotherapy in patients with de novo metastatic PDAC and disease progression on front-line gemcitabine-based therapy (NCT02826486). Subjects received a priming phase of motixafortide daily on days 1-5, followed by repeated cycles of motixafortide twice a week; pembrolizumab every 3 weeks; and nanoliposomal irinotecan, fluorouracil, and leucovorin every 2 weeks (NAPOLI-1 regimen). The primary objective was objective response rate (ORR). Secondary objectives included overall survival (OS), progression-free survival (PFS), disease control rate (DCR), safety, and tolerability. RESULTS: A total of 43 patients were enrolled. The ORR according to RECISTv1.1 was 21.1% with confirmed ORR of 13.2%. The DCR was 63.2% with median duration of clinical benefit of 5.7 months. In the intention-to-treat population, median PFS was 3.8 months and median OS was 6.6 months. The triple combination was safe and well tolerated, with toxicity comparable with the NAPOLI-1 regimen. Notably, the incidence of grade 3 or higher neutropenia and infection was 7%, lower than expected for this chemotherapy regimen. CONCLUSIONS: Triple combination of motixafortide, pembrolizumab, and chemotherapy was safe and well tolerated, and showed signs of efficacy in a population with poor prognosis and aggressive disease.

RESUMO

BACKGROUND: Recent studies support the use of gemcitabine and nab-paclitaxel in adults with locally advanced unresectable or metastatic pancreatic adenocarcinoma although insufficient data are available on prognostic and predictive markers of response to treatment. OBJECTIVE: The objective of this study is to identify treatment response markers in patients with locally advanced unresectable or metastatic pancreatic adenocarcinoma. MATERIALS AND METHODS: This is an observational, retrospective, and multicenter study. Sociodemographic, clinical, and therapeutic data were collected. Cox regression models were applied to determine associations. RESULTS: In total, 39 patients were included; 23.1% presented locally advanced pancreatic cancer and 76.9% metastatic disease. They received a mean of 6 ± 3 treatment cycles; 59% required dose reduction, 59% treatment delay, and 20.5% switched to a biweekly regimen. The overall response rate was 23% and the disease control rate was 81%. Median progression-free survival was 9 months and median overall survival (OS) was 15 months. A higher neutrophil/lymphocyte ratio (NLR) was significantly associated with lower OS. We reported Grades 1-4 nonhematological and hematological toxicities. CONCLUSION: NLR is a useful prognostic factor for OS in patients with locally advanced unresectable or metastatic pancreatic adenocarcinoma treated with gemcitabine and nab-paclitaxel. Moreover, we suggest that a biweekly regimen is an option for certain groups of patients.

RESUMO

AIM: To evaluate the efficacy and safety of erlotinib plus capecitabine for metastatic pancreatic cancer. PATIENTS AND METHODS: This was a multicenter, uncontrolled, phase II trial. Patients with untreated metastatic pancreatic cancer received oral capecitabine at 1,000 mg/m(2) twice daily on days 1-14, of a 21-day treatment cycle; and oral erlotinib at 150 mg daily. RESULTS: Thirty-two patients were enrolled. The overall response rate (ORR) was 6%, with a median time to treatment failure of 2.1 months. The median follow-up was 7.6 months. The median progression-free survival was 2.1 months and median overall survival was 4.3 months. The one-year survival rate was 22%. Major grade 1 and 2 non-hematological toxicities were skin rash (34%), asthenia (31%) and diarrhea (31%). Grade 3 hematological toxicity was <13%. No grade 4 toxicities were detected. None of the patients died due to treatment toxicity. CONCLUSION: The combination of capecitabine with erlotinib is an active regimen with a favorable safety profile for patients with metastatic pancreatic cancer.
