Background Lenvatinib is approved as first-line treatment for patients with advanced hepatocellular carcinoma (HCC). The efficacy of lenvatinib in Caucasian real-world patients is insufficiently defined. The purpose of this study was to evaluate the efficacy of lenvatinib in a multi-center cohort (ELEVATOR) from Germany and Austria. Methods A retrospective data analysis of 205 patients treated with first-line systemic lenvatinib at 14 different sites was conducted. Overall survival, progression free survival, overall response rate and adverse event rates were assessed and analyzed. Results Patients receiving lenvatinib in the real-world setting reached a median overall survival of 12.8 months, which was comparable to the results reported from the REFLECT study. Median overall survival (mOS) and progression free survival (mPFS) was superior in those patients who met the inclusion criteria of the REFLECT study compared to patients who failed to meet the inclusion criteria (mOS 15.6 vs 10.2 months, HR 0.55, 95% CI 0.38-0.81, p=0.002; mPFS 8.1 vs 4.8 months HR 0.65, 95% CI 0.46-0.91, p=0.0015). For patients with an impaired liver function according to the Albumin-Bilirubin (ALBI) grade, or reduced ECOG performance status ≥2, survival was significantly shorter compared to patients with sustained liver function (ALBI grade 1) and good performance status (ECOG performance status 0), respectively (HR 1.69, 95% CI 1.07-2.66, p=0.023; HR 2.25, 95% CI 1.19-4.23, p=0.012). Additionally, macrovascular invasion (HR 1.55, 95% CI 1.02-2.37, p=0.041) and an AFP ≥200 ng/mL (HR 1.56, 95% CI 1.03-2.34, p=0.034) were confirmed as independent negative prognostic factors in our cohort of patients with advanced HCC. Conclusion Overall, our data confirm the efficacy of lenvatinib as first-line treatment and did not reveal new or unexpected side effects in a large retrospective Caucasian real-world cohort, supporting the use of lenvatinib as meaningful alternative for patients that cannot be treated with IO-based combinations in first-line HCC.
Abstract Based on results of prior trials (TAGS, REGARD, RAINBOW), the combination of ramucirumab beyond progression with TAS‐102 (trifluridine/tipiracil) seems to be promising in advanced esophagogastric adenocarcinoma (EGA). In this multicenter, non‐randomized, open‐label, investigator‐initiated pilot trial, ramucirumab‐pretreated patients with metastatic EGA received a maximum of 4 cycles of ramucirumab (8 mg/kg i.v. on day 1 and 15, Q2W) plus TAS‐102 (35 mg/m 2 p.o. bid on day 1‐5 and day 8‐12; Q2W). Primary endpoint was tolerability and toxicity, defining a positive trial if the SAE rate according to CTCAE 5.0 will increase <30% (up to 55%) compared to historical results from TAGS trial (SAE rate 43%). Secondary endpoints were further evaluation of safety and assessment of efficacy according to tumor response and overall and progression‐free survival (OS/PFS). Twenty patients, 20% gastric and 80% GEJ cancers and 55% with ECOG 0 were enrolled. In total, nine SAEs were reported in 25% [95% CI: 8.7‐49.1] of the patients, all without relationship to the systemic therapy. The median OS and PFS were 9.1 months [5.4‐10.1] and 2.9 months [1.7‐4.8], respectively. In addition, a disease control rate of 45% was obtained. The trial showed a favorable safety profile with a numerically lower incidence of SAEs for the combination of ramucirumab with TAS‐102 compared to historical TAGS trial. Furthermore, the combination demonstrated efficacy in the beyond progression setting and therefore warrants further evaluation in a randomized trial compared to TAS‐102 alone.
359 Background: Based on results of prior trials (TAGS, REGARD, RAINBOW), it seems promising to combine Ramucirumab (Ram) beyond progression (PD) with TAS-102 (trifluridine/tipiracil). The purpose of RE-ExPEL is to investigate the tolerability, safety and benefit of Ram beyond PD in combination with TAS-102 in advanced esophagogastric adenocarcinoma (EGA). Methods: This is a multicenter, non-randomized, open-label investigator initiated pilot trial. 20 ram-pretreated patients (pts) with advanced EGA were enrolled to a maximum of 4 cycles of ramucirumab 8mg/kg every two weeks (days 1, 15; qd28) plus TAS-102 35 mg/m 2 /p.o. bid (d1-5 and d8-12; qd28). Primary endpoint (EP) was tolerability and toxicity, defining a positive trial if SAE rate according (acc.) to CTCAE 5.0 will increase less than 30% (up to 55%) compared with results from TAGS (SAE-rate 43%). Secondary EPs are further safety data and efficacy data, OS, PFS and ORR. Results: 20 pts (20% female) were enrolled between Oct 2020 and Aug 2021, 20% gastric and 80% GEJ- cancers, 55% of pts with ECOG 0. Results of the final analysis showed that only 25% of pts had at least one SAE and the total no. of SAEs was 9, one with fatal outcome, all without relationship to systemic therapy and no SUSAR reported. RE-ExPEL was able to show a median OS of 9.07 mo (95% CI 5.42-10.09) and a DCR of 45%. 90% of pts got study medication in 3 rd line whereas 10% were even further line pts. Conclusions: The safety data showed a favorable safety profile with a low rate of severe toxicity for ram+TAS-102, maybe due to the long disease stabilization and therefore less tumor associated symptoms. Regarding the primary safety endpoint, the trial was positive with even a numerically lower SAE rate compared with TAGS. Furthermore, RE-ExPEL was able to show very promising efficacy data for the combination ram plus TAS-102 with median OS of 9.07 mo. Ram+TAS-102 seems to be more effective than TAS-102 alone acc. to TAGS-trial respecting the limitation of the RE-ExPEL one arm study design with only 20pts. The combination needs further evaluation in a randomized phase III trial. Clinical trial information: NCT04517747 .
Metabolomic approaches in prospective cohorts may offer a unique snapshot into early metabolic perturbations that are associated with a higher risk of cardiovascular diseases (CVD) in healthy people. We investigated the association of 105 serum metabolites, including acylcarnitines, amino acids, phospholipids and hexose, with risk of myocardial infarction (MI) and ischemic stroke in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam (27,548 adults) and Heidelberg (25,540 adults) cohorts. Using case-cohort designs, we measured metabolites among individuals who were free of CVD and diabetes at blood draw but developed MI (n = 204 and n = 228) or stroke (n = 147 and n = 121) during follow-up (mean, 7.8 and 7.3 years) and among randomly drawn subcohorts (n = 2214 and n = 770). We used Cox regression analysis and combined results using meta-analysis. Independent of classical CVD risk factors, ten metabolites were associated with risk of MI in both cohorts, including sphingomyelins, diacyl-phosphatidylcholines and acyl-alkyl-phosphatidylcholines with pooled relative risks in the range of 1.21–1.40 per one standard deviation increase in metabolite concentrations. The metabolites showed positive correlations with total- and LDL-cholesterol (r ranged from 0.13 to 0.57). When additionally adjusting for total-, LDL- and HDL-cholesterol, triglycerides and C-reactive protein, acyl-alkyl-phosphatidylcholine C36:3 and diacyl-phosphatidylcholines C38:3 and C40:4 remained associated with risk of MI. When added to classical CVD risk models these metabolites further improved CVD prediction (c-statistics increased from 0.8365 to 0.8384 in EPIC-Potsdam and from 0.8344 to 0.8378 in EPIC-Heidelberg). None of the metabolites was consistently associated with stroke risk. Alterations in sphingomyelin and phosphatidylcholine metabolism, and particularly metabolites of the arachidonic acid pathway are independently associated with risk of MI in healthy adults.
Elevated liver enzyme concentrations in blood are indicative of liver diseases and may provide an early signal for being at risk for other chronic diseases. Our study aimed to assess the relationships of alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), alanine aminotransferase (ALT), aspartate transaminase (AST) and the De Ritis ratio (AST/ALT) with incidence and mortality of cardiovascular diseases (CVD) and the four most common cancers, that is, breast, prostate, colorectal and lung.We analysed a case-cohort sample of the prospective European Prospective Investigation into Cancer and Nutrition-Heidelberg cohort, including cancer (n=1632), cancer mortality (n=761), CVD (n=1070), CVD mortality (n=381) and a random subcohort (n=2739) with an average follow-up duration of 15.6 years. Concentrations of liver enzymes were measured in prediagnostic blood samples and Prentice-weighted Cox regression models were used to estimate HRs with 95% CIs.High ALP levels were associated with increased risk for lung cancer and all-cause mortality (highest vs lowest quartile, multivariable adjusted HR=2.39 (95% CI 1.30 to 4.39), HR=1.31 (95% CI 1.02 to 1.67)), high AST levels with all-cause mortality (HR=1.45 (95% CI 1.15 to 1.82)), and a high De Ritis ratio with prostate cancer risk, all-cause and cancer mortality (HR=1.61 (95% CI 1.10 to 2.36), HR=1.60 (95% CI 1.25 to 2.04), HR=1.67 (95% CI 1.26 to 2.23)). Using cut-points for liver enzyme levels above normal, we observed positive associations for all-cause mortality with ALP, GGT and AST, and assigning a combined risk score resulted in positive associations with all-cause and cause-specific mortality.Measurements of serum liver enzymes, as routinely performed in health check-ups, may support the identification of individuals at increased risk for all-cause mortality. Further prospective studies are needed to verify our first results on individual cancers and on a combined risk score.
Chronic lymphocytic leukemia (CLL) is a chronic disease that often progresses slowly from a precursor stage, monoclonal B-cell lymphocytosis (MBL), and that can remain undiagnosed for a long time.
Experimental and epidemiological studies demonstrate a role for 27-hydroxycholesterol (27HC) in breast cancer development, though results are conflicting. Cholesterol 27-hydroxylase (CYP27A1) and oxysterol 7-alpha-hydroxylase (CYP7B1) regulate 27HC concentrations, while differential expression of the liver X receptor (LXR) and estrogen receptor beta (ERβ) may impact the association between 27HC and breast cancer risk.We evaluated correlates of tumor tissue expression of CYP27A1, CYP7B1, LXR-β, and ERβ and the association between circulating prediagnostic 27HC concentrations and breast cancer risk by marker expression in a nested case-control study within the European Prospective Investigation into Cancer and Nutrition (EPIC)-Heidelberg cohort including 287 breast cancer cases with tumor tissue available. Tumor protein expression was evaluated using immunohistochemistry, and serum 27HC concentrations quantified using liquid chromatography-mass spectrometry. Conditional logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).A higher proportion of CYP7B1-positive cases were progesterone receptor (PR)-positive, relative to CYP7B1-negative cases, whereas a higher proportion of ERβ-positive cases were Bcl-2 low, relative to ERβ-negative cases. No differences in tumor tissue marker positivity were observed by reproductive and lifestyle factors. We observed limited evidence of heterogeneity in associations between circulating 27HC and breast cancer risk by tumor tissue expression of CYP27A1, CYP7B1, LXR-β, and ERβ, with the exception of statistically significant heterogeneity by LXR-β status in the subgroup of women perimenopausal at blood collection (p = 0.02).This exploratory study suggests limited associations between tumor marker status and epidemiologic or breast cancer characteristics. Furthermore, the association between circulating 27HC and breast cancer risk may not vary by tumor expression of CYP27A1, CYP7B1, LXR-β, or ERβ.
Abstract Introduction The relationship between circulating prolactin and invasive breast cancer has been investigated previously, but the association between prolactin levels and in situ breast cancer risk has received less attention. Methods We analysed the relationship between pre-diagnostic prolactin levels and the risk of in situ breast cancer overall, and by menopausal status and use of postmenopausal hormone therapy (HT) at blood donation. Conditional logistic regression was used to assess this association in a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, including 307 in situ breast cancer cases and their matched control subjects. Results We found a significant positive association between higher circulating prolactin levels and risk of in situ breast cancer among all women [pre-and postmenopausal combined, OR log2 = 1.35 (95% CI 1.04-1.76), P trend = 0.03]. No statistically significant heterogeneity was found between prolactin levels and in situ cancer risk by menopausal status (P het = 0.98) or baseline HT use (P het = 0.20), although the observed association was more pronounced among postmenopausal women using HT compared to non-users (P trend = 0.06 vs P trend = 0.35). In subgroup analyses, the observed positive association was strongest in women diagnosed with in situ breast tumors <4 years compared to ≥4 years after blood donation (P trend = 0.01 vs P trend = 0.63; P het = 0.04) and among nulliparous women compared to parous women (P trend = 0.03 vs P trend = 0.15; P het = 0.07). Conclusions Our data extends prior research linking prolactin and invasive breast cancer to the outcome of in situ breast tumours and shows that higher circulating prolactin is associated with increased risk of in situ breast cancer.
