Associating Appendicitis with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD): A Novel Insight into an Unexpected Connection. J Clin Med 2024; 13:1319. [PMID: 38592145 PMCID: PMC10932235 DOI: 10.3390/jcm13051319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 02/09/2024] [Accepted: 02/14/2024] [Indexed: 04/10/2024] Open
Abstract
BACKGROUND The gut microbiome modulates the liver immune microenvironment and is deeply integrated into the pathophysiology of metabolic dysfunction-associated steatotic liver disease (MASLD). Appendectomies, which are performed in almost all patients diagnosed with appendicitis, cause long-term alterations to the gut microbiome, providing a potential link with the development of MASLD. We therefore investigated a potential link between appendicitis and the presence of MASLD in a large cohort of outpatients in Germany. METHODS The present study included 26,717 individuals with and 26,717 without appendicitis. Univariable Cox-regression analyses were conducted to assess the association between appendicitis and MASLD. RESULTS During the long-term follow-up, 4.8% of patients with appendicitis and 3.4% of those in the non-appendicitis group were diagnosed with MASLD (p < 0.001), corresponding to an incidence of 5.4 (appendicitis cohort) versus 3.5 (non-appendicitis cohort) cases per 1000 patient years. These findings were confirmed in regression analysis, revealing a strong and statistically significant association between appendicitis and the development of MASLD (HR: 1.57; 95% CI: 1.39-1.78). This link was observed for all age groups and was independent of patients' sex. CONCLUSION We provide evidence from a large cohort of outpatients in Germany suggesting a link between appendicitis and MASLD. This might help to better stratify patients according to their individual risk for the development of chronic liver diseases.

Abstract
721 Background: Second-line Nal-Iri/5-Fluorouracil/Folinic Acid (Nal-Iri/5-FU/LV) increases overall survival of unselected patients (pts) with metastatic pancreatic ductal adenocarcinoma (PDAC) after gemcitabine-based therapy. It is unknown, which pts will likely benefit or could probably profit more from alternative approaches. Methods: In this prospective trial, 156 pts with locally advanced or metastatic PDAC were included for treatment with biweekly Nal-Iri/5-FU/LV (70 mg/m², 2.4 g/m², 400 mg/m²) after failure of 1st line chemotherapy with Gemcitabine/nab-Paclitaxel, with comprehensive evaluation of prior treatment characteristics, potential predictive factors, and quality of life. Primary end point is the correlation of time to treatment failure (TTF) of 1st and 2nd line therapy. Moreover, translational research was done to measure and evaluate biomarkers in blood and tumor tissue. Here, we explore patient characteristics in two subgroups with short or long treatment duration, with the aim to evaluate potential predictive factors for further analysis. Results: 139 (90%) of the 156 pts included between 03/2018 and 07/2021 in 40 German sites received medication. End of treatment is documented for 128 pts, with 5 still on treatment as of 05/2022 Mean (±SD) treatment duration was 15.5 weeks or 7.7±7.1 cycles (median 7 weeks; 5 cycles). 37 (25%) pts received ≥ 10 cycles. The median was used to separate two subgroups of short and long treatment duration (STD, ≤ 5 cycles, n=66 (52%) vs. LTD, > 5 cycles, n=62, (48%)). Reasons for treatment discontinuation clearly differed between the two subgroups: death in 9% vs. 3%, toxicity in 9% vs. 2%, unrelated medical condition in 12% vs. 2%, and progressive disease in 46% vs. 73%, respectively. Investigator´s decision was a reason for discontinuation in 6% vs. 5%. Pts with STD had a lower performance status (ECOG 1 or 2 in 74% vs. 52%, ECOG 0 in 20% vs. 44% in STD vs. LTD group), lower albumin levels (below normal in 36% vs. 24.2%) and were more likely to suffer from liver metastases (overall 82% vs. 66%). There were no relevant differences with regard to age, sex and tumor burden (number of metastases or CA19-9 levels). Conclusions: Early treatment discontinuation was primarily associated with patient-related factors such as low performance status, low albumin levels and comorbidities, characteristics which could be used to spare patients from treatment with an unfavorable risk-to-benefit ratio. In contrast, surrogate markers for tumor burden did not correlate with treatment success. Clinical trial information: NCT03468335 .

Abstract
694 Background: Perioperative chemotherapy (CTX) in resectable pancreatic adenocarcinoma (rPDAC) is still not considered SoC and data regarding efficacy but also quality of life (QoL) are limited. NEONAX is a prospective, randomized phase II trial in patients with rPDAC with two independent experimental arms examining perioperative (2 pre- and 4 postoperative cycles, arm A) or adjuvant (6 cycles, arm B) of Gem (1000mg/m2) and nab-P (125mg/m2) on days 1,8,15 of a 28-day cycle. The primary endpoint DFS at 18 mo. as well as DFS, OS and safety have already been reported. Here we present the QoL data of the NEONAX trial. Methods: QoL was evaluated by EORTC QLQ-C30, EORTC QLQ-PAN26 and HADS-D questionnaires at baseline, at the beginning of each CTX cycle (neoadj. and adj. in arm A, only adj. in arm B), after neoadj. treatment in arm A as well as prior and post resection and after 6 cycles of CTX. Results: Global health status score (GHS-score) (QLQ-C30) showed no difference between baseline (t1) and the timepoint after 6 cycles of CTX (t2) in the perioperative arm A (66.7/100 at both timepoints). Here patients experienced the lowest GHS-score pre- and postoperatively (50/100 in both cases). Adjuvant arm B showed a deterioration in the GHS-score of 12.5 points from timepoint 1 to 2 (62.5/100 to 50.0/100). Here the lowest GHS-score was observed within 4 weeks post-surgery (41.7/100). Physical function score (QLQ-C30) was decreased by 6.7 points (86.7/100 to 80/100) in perioperative arm A and by 26.7 points (86.7/100 to 60/100) in arm B between both timepoints. Role function (QLQ-C30) was reduced by 16.7 points (83.3/100 to 66.7/100) in arm A and by 33.3 points (83.3/100 to 50/100) in arm B between both timepoints. In the remaining subscales of the used questionnaires the two arms of the trial showed comparable median scores over the whole study period. The number of submitted questionnaires at each timepoint varied but was at large comparable in both arms. Conclusions: QoL was largely preserved in the perioperative as well as the adjuvant arm of the NEONAX trial. GHS-score was lower pre-and postoperatively in arm A. The lowest GHS-score was observed postoperatively in the adjuvant arm B. QoL was restored at the end of the treatment period in the perioperative arm A and remained slightly reduced in arm B suggesting that QoL is not substantially impaired by perioperative treatment in rPDAC. Clinical trial information: NCT02047513 . [Table: see text]

Perioperative or only adjuvant gemcitabine plus nab-paclitaxel for resectable pancreatic cancer (NEONAX)-a randomized phase II trial of the AIO pancreatic cancer group. Ann Oncol 2023; 34:91-100. [PMID: 36209981 DOI: 10.1016/j.annonc.2022.09.161] [Citation(s) in RCA: 25] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 09/26/2022] [Accepted: 09/27/2022] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Data on perioperative chemotherapy in resectable pancreatic ductal adenocarcinoma (rPDAC) are limited. NEONAX examined perioperative or adjuvant chemotherapy with gemcitabine plus nab-paclitaxel in rPDAC (National Comprehensive Cancer Network criteria). PATIENTS AND METHODS NEONAX is a prospective, randomized phase II trial with two independent experimental arms. One hundred twenty-seven rPDAC patients in 22 German centers were randomized 1 : 1 to perioperative (two pre-operative and four post-operative cycles, arm A) or adjuvant (six cycles, arm B) gemcitabine (1000 mg/m2) and nab-paclitaxel (125 mg/m2) on days 1, 8 and 15 of a 28-day cycle. RESULTS The primary endpoint was disease-free survival (DFS) at 18 months in the modified intention-to-treat (ITT) population [R0/R1-resected patients who started neoadjuvant chemotherapy (CTX) (A) or adjuvant CTX (B)]. The pre-defined DFS rate of 55% at 18 months was not reached in both arms [A: 33.3% (95% confidence interval [CI] 18.5% to 48.1%), B: 41.4% (95% CI 20.7% to 62.0%)]. Ninety percent of patients in arm A completed neoadjuvant treatment, and 42% of patients in arm B started adjuvant chemotherapy. R0 resection rate was 88% (arm A) and 67% (arm B), respectively. Median overall survival (mOS) (ITT population) as a secondary endpoint was 25.5 months (95% CI 19.7-29.7 months) in arm A and 16.7 months (95% CI 11.6-22.2 months) in the upfront surgery arm. This difference corresponds to a median DFS (mDFS) (ITT) of 11.5 months (95% CI 8.8-14.5 months) in arm A and 5.9 months (95% CI 3.6-11.5 months) in arm B. Treatment was safe and well tolerable in both arms. CONCLUSIONS The primary endpoint, DFS rate of 55% at 18 months (mITT population), was not reached in either arm of the trial and numerically favored the upfront surgery arm B. mOS (ITT population), a secondary endpoint, numerically favored the neoadjuvant arm A [25.5 months (95% CI 19.7-29.7months); arm B 16.7 months (95% CI 11.6-22.2 months)]. There was a difference in chemotherapy exposure with 90% of patients in arm A completing pre-operative chemotherapy and 58% of patients starting adjuvant chemotherapy in arm B. Neoadjuvant/perioperative treatment is a novel option for patients with resectable PDAC. However, the optimal treatment regimen has yet to be defined. The trial is registered with ClinicalTrials.gov (NCT02047513) and the European Clinical Trials Database (EudraCT 2013-005559-34).

Prognostic and predictive value of CA 19-9 in locally advanced pancreatic cancer treated with multiagent induction chemotherapy: results from a prospective, multicenter phase II trial (NEOLAP-AIO-PAK-0113). ESMO Open 2022; 7:100552. [PMID: 35970013 PMCID: PMC9434418 DOI: 10.1016/j.esmoop.2022.100552] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 06/30/2022] [Accepted: 07/03/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND The prognostic and predictive value of carbohydrate antigen 19-9 (CA 19-9) in locally advanced pancreatic cancer (LAPC) has not yet been defined from prospective randomized controlled trials (RCTs). PATIENTS AND METHODS A total of 165 LAPC patients were treated within the NEOLAP RCT for 16 weeks with multiagent induction chemotherapy [ICT; either nab-paclitaxel/gemcitabine alone or nab-paclitaxel/gemcitabine followed by FOLFIRINOX (combination of fluorouracil, leucovorin, irinotecan, and oxaliplatin)] followed by surgical exploration of all patients without evidence of disease progression. CA 19-9 was determined at baseline and after ICT and correlated with overall survival (OS) and secondary R0 resection rate. RESULTS From the NEOLAP study population (N = 165) 133 patients (81%) were evaluable for CA 19-9 at baseline and 81/88 patients (92%) for post-ICT CA 19-9 response. Median OS (mOS) in the CA 19-9 cohort (n = 133) was 16.2 months [95% confidence interval (CI) 13.0-19.4] and R0 resection (n = 31; 23%) was associated with a significant survival benefit [40.8 months (95% CI 21.7-59.8)], while R1 resected patients (n = 14; 11%) had no survival benefit [14.0 (95% CI 11.7-16.3) months, hazard ratio (HR) 0.27; P = 0.001]. After ICT most patients showed a CA 19-9 response (median change from baseline: -82%; relative decrease ≥55%: 83%; absolute decrease to ≤50 U/ml: 43%). Robust CA 19-9 response (decrease to ≤50U/ml) was significantly associated with mOS [27.8 (95% CI 18.4-37.2) versus 16.5 (95% CI 11.7-21.2) months, HR 0.49; P = 0.013], whereas CA 19-9 baseline levels were not prognostic for OS. Multivariate analysis demonstrated that a robust CA 19-9 response was an independent predictive factor for R0 resection. Using a CA 19-9 decrease to ≤61 U/ml as optimal cut-off (by receiver operating characteristic analysis) yielded 72% sensitivity and 62% specificity for successful R0 resection, whereas CA 19-9 nonresponders (<20% decrease or increase) had no chance for successful R0 resection. CONCLUSIONS CA 19-9 response after multiagent ICT provides relevant prognostic and predictive information and is useful in selecting LAPC patients for explorative surgery.

Abstract
4133 Background: Perioperative chemotherapy (CTX) in resectable pancreatic ductal adenocarcinoma (PDAC) is still not considered standard of care and data are limited. The NEONAX trial examined gemcitabine (Gem) plus nab-paclitaxel (nab-P), in the perioperative or adjuvant therapy of resectable PDAC (NCCN criteria). Methods: NEONAX is a prospective, randomized phase II trial with two independent experimental arms. 127 resectable PDAC patients in 22 German centers were randomized 1:1 to perioperative (2 pre- and 4 postoperative cycles, arm A) or adjuvant (6 cycles, arm B) of Gem (1000mg/m2) and nab-P (125mg/m2) on days 1,8,15 of a 28-day cycle. Results: We previously reported the primary endpoint disease free survival (DFS) at 18 mo. in the modified intention-to-treat (ITT)-population (defined as R0/R1 resected pts. that either started neoadjuvant (A) or adjuvant (B) CTX. The pre-defined DFS rate of 55% at 18 mo. was not reached in both arms (A: 32.2%, B: 41.4%). Here we present the final results of the secondary endpoints median overall survival (mOS), pN0-resection rate, perioperative morbidity/mortality and safety in the ITT-population. Most common grade ≥3 treatment emergent adverse events in the safety population were neutropenia (arm A 21.1%, arm B 12.3%), fatigue (arm A 8.8%, arm B 5.3%) and anemia (arm A 10.5%, arm B 1.8%). The most frequent post-/perioperative complications of all grades in pts. undergoing resection were infections (arm A: 24.4%, arm B: 8.8%), pancreatic fistulas (arm A: 14.6%; arm B: 13.3%) and bleedings (arm A: 9.7%; arm B: 6.7%). Perioperative mortality was 2.4% in the neoadjuvant and 6.7% in the upfront surgery setting. The median number of resected lymph nodes was comparable in both arms (A: n = 21, B: n = 26). The pN0-resection rate was 33.3% in the neoadjuvant/perioperative arm A and 29.5% in the upfront surgery arm B. R0 resection rates were 87.8% in arm A and 67.4% in arm B, respectively. Median OS as a key secondary endpoint in the ITT population was 25.2 mo. in arm A and 16.7 mo. for upfront surgery, a difference of 8.5 mo. This difference corresponds to a mDFS of 11.5 mo. in arm A and 5.9 mo. in arm B. 91.5% of pts. in arm A started and 84.7% completed neoadjuvant CTX but only 42.4% of pts. in arm B started adjuvant CTX. Conclusions: Perioperative treatment with Gem/nab-P was well tolerated and showed an encouraging mOS of 25.2 mo., this is well in the range of the data in SWOG 1505 (23.6 mo.) or PREOPANC (15.7 mo.). The corresponding mOS in the upfront surgery arm was 16.7 mo. The 8.5 mo. difference may be explained by the fact that many pts. in arm B did not receive adjuvant treatment whereas the vast majority of pts. in arm A completed at least preoperative CTX. Neoadjuvant/perioperative treatment is a promising novel option for pts. with resectable PDAC. The optimal treatment regimen is subject of current clinical trials.

IMMUTACE: A biomarker-orientated phase II, single-arm, open-label AIO study of transarterial chemoembolization (TACE) in combination with nivolumab performed for intermediate-stage hepatocellular carcinoma (HCC; AIO-HEP-0217)—Updated efficacy results. J Clin Oncol 2022. [DOI: 10.1200/jco.2022.40.16_suppl.4116] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
4116 Background: Immunotherapy based combinations recently revolutionized the treatment of patients (pts) with advanced HCC, but its significance in earlier stages remains to be determined. TACE is commonly used as first line treatment in intermediate HCC, but outcome of patients treated with TACE in real-life cohorts is still poor with a median overall survival (OS) below 20 months. The aim of this study was to determine the safety and efficacy of TACE combined with nivolumab. Methods: This is a phase II trial, that recruited 59 patients at 10 sites in Germany between 06/2018 and 06/2020. Pts received up to two TACE treatments followed by nivolumab (240 mg/ Q2W), initiated on day 2-3 after the first TACE session and continued until progression for a maximum treatment duration of two years. Primary endpoint was ORR (mRECIST; with ORR exceeding 55% (power = 80%; actual beta 0.17) as promising for further investigations). Secondary endpoints include mPFS, mTTFS (median time to failure of strategy), mOS, QoL, and safety/tolerability. Tumor tissue was obtained at baseline and blood samples were collected longitudinally for translational research. Results: 49 pts (14.3% HCV and 8.2% HBV) were enrolled and received at least one dose of nivolumab, median tumor size was 4.5 cm (0.9 – 15 cm) and median number 3 (1 – 12). ORR by mRECIST was 71.4% (CR: 16.3%, PR: 55.1%, SD 4.1%, PD: 14.3%). At a median follow-up of 20 months, mPFS was 7.2 mo (95% CI; 5.3 – 11.2; 40 events), mTTFS was 11.2 mo (95% CI; 7.2, 13.5; 42 events) and mTTSST (median time to subsequent systemic therapy) was 24.9 mo (95% CI; 12.2, - ; 21 events). Median duration of Nivolumab was 8.3 months and mOS was 28.3 mo (95% CI; 20 – not estimable; 23 events). Grade ≥3 treatment-related adverse events occurred in 34.7% of patients. Correlative analysis of efficacy with genetic alterations, gene expression signatures and changes of immune cell populations will be reported soon. Conclusions: The study met its primary endpoint and provides evidence for the efficacy of TACE in combination with nivolumab without new safety signals in pts with intermediate HCC and no prior systemic therapy. Our findings support further evaluation of nivolumab-based combinations for the treatment of intermediate HCC. Disclaimer: This study was supported with drug and funding by Bristol-Myers-Squibb. Clinical trial information: NCT03572582.

Abstract
4008 Background: Chemotherapy (CT) is the standard of care in nonresectable locally advanced pancreatic cancer. The CONKO-007 trial studied the role of sequential CT and chemoradiotherapy (CRT). Methods: In this randomized multicenter phase III trial resectability was judged by an independent surgical board. Patients (pts) received induction chemotherapy (IC) for 3 months (3 cycles gemcitabine (Gem, 1000 mg/m² d1, 8, 15, q4w) or FOLFIRINOX (6 cycles, q2w)). After IC pts without progression were randomized to either continuing CT for another 3 months or receiving CRT (cumulative dose of 50.4Gy, single dose 1.8Gy + Gem 300 mg/m² weekly, followed by 1 cycle of Gem 1000 mg/m² at d1, 8, 15). The primary endpoint of the study was overall survival (OS) since the begin of IC. Determination of sample size calculated 590 pts to be randomized. Due to the exclusion of pts with progressive disease after IC a total of 830 pts should be enrolled. Due to delayed patient accrual the primary endpoint was changed to R0 resection rate resulting in an estimated sample size of 525 pts. Results: Between 04/2013 and 02/2021 a total of 525 pts were enrolled in 47 sites. 402 pts received IC with FOLFIRINOX and 93 pts with Gem. After IC 190 pts were excluded due to progression or toxicity, 335 were randomized, their median FU was 16 months. Hematological toxicities were significantly increased in the CRT arm, non-hematological toxicities were comparable. R0 CRM- resection rate and pCR rate was significantly higher in the CRT arm. R1-resections occurred significantly more often in the CT arm. Median progression-free survival (PFS) (HR 0.919, 95% CI 0.702-1.203, p=0.540) and OS (HR 0.964, 95% CI 0.760-1.225, p=0.766) did not differ significantly in both arms, whereas the PFS rate tended to be higher in the CRT arm after 2 years. OS rates for CRM- R0 surgery with 87.5. ± 0.05% (1y) and 67.2 ± 0.05% (2y) were significantly higher (p<0.01) than for CRM+ R0 surgery with 66.7 ± 0.15% (1y) and 41.2 ± 0.1% (2y) as well as for patients without or incomplete surgery with 68.5 ± 0.03% (1y) and 26.4 ± 0.03% (2y). Conclusions: The addition of radiotherapy after IC improves the R0 CRM - resection and pCR rate without significant change in R0 resection rate (primary endpoint). Pts with R0 CRM - resections had a better prognosis compared to patients with either R0 CRM+ or incomplete or without surgery. However, this effect on resectability did not translate into a statistically significant PFS or OS benefit in the whole cohort. Clinical trial information: NCT01827553. [Table: see text]

Abstract
The combination of the anti-PD-L1 antibody atezolizumab and the anti-VEGF bevacizumab is the first approved immunotherapeutic regimen for first-line therapy in patients with unresectable hepatocellular carcinoma (HCC), currently approved in more than 80 countries. The efficacy and tolerability of this regimen suggest that the use of atezolizumab + bevacizumab could be extended to the treatment of patients with intermediate-stage HCC in combination with transarterial chemoembolization (TACE). The authors describe the rationale and design of the DEMAND study. This investigator-initiated, multicenter, randomized phase II study is the first trial to evaluate the safety and efficacy of atezolizumab + bevacizumab prior to or in combination with TACE in patients with intermediate-stage HCC. The primary end point is the 24-month survival rate; secondary end points include objective response rate, progression-free survival, safety and quality of life. Clinical Trial Registration: NCT04224636 (ClinicalTrials.gov).

The efficacy and tolerability of this regimen suggests that its use could be extended to the treatment of patients with intermediate-stage HCC in combination with transarterial chemoembolization (TACE). The effect of TACE combined with atezolizumab and bevacizumab could improve response and tumor control as well as prevent disease progression in non-responders to TACE. Response to the early use of immunotherapy could also reduce the number and extent of TACE cycles needed to achieve tumor control, thereby contributing to the prevention of collateral damage to the liver parenchyma and preservation of liver function. Initiating immunotherapy first may also promote the access of circulating lymphocytes into tumor lesions. The DEMAND study investigates the efficacy and ideal sequence of TACE and immunotherapy in intermediate stage HCC. Methods: This investigator-initiated, multi-center, randomized, open-label phase 2 trial is the first study to evaluate the safety and efficacy of atezolizumab and bevacizumab prior to, or in combination with TACE in patients with unresectable HCC. 106 patients (Barcelona Clinic Liver Cancer Stage A not amenable to curative therapy or B, Child-Pugh A or B7, Eastern Cooperative Oncology Group performance status 0 or 1, no prior TACE) will be randomized in a 1:1 ratio to receive either up-front atezolizumab and bevacizumab followed by TACE selectively directed against progressive lesions (Arm A, 53 patients), or TACE and synchronous treatment with atezolizumab and bevacizumab (Arm B, 53 patients). Patients receive study treatment until loss of clinical benefit or unacceptable toxicity for up to 24 months. The use of local ablation is allowed for the treatment of lesions which cannot be targeted sufficiently selectively by TACE, or of de-novo lesions. The primary endpoint is the 24-month survival rate; secondary endpoints include objective response rate, progression-free survival, safety and quality of life. Translational analyses aim at identifying predictive biomarkers and focus on immune cell phenotyping in tumor and peripheral blood, circulating tumor DNA and changes in the diversity of the gut microbiome. Recruitment is ongoing in 15 German centers with 21 of 106 patients randomized. Clinical trial information: NCT04224636.

Abstract
Biliary tract cancers (BTC) are rare but aggressive. Due to limited anti-tumor effects of current second- and later-line treatment regimens, novel treatment options are required. Nanoliposomal irinotecan in combination with leucovorin and 5-fluorouracil (FOLFnal-IRI) achieved promising results as a second-line treatment in patients with pancreatic cancer, warranting further investigation in BTC. In the present study, a retrospective analysis of patients receiving FOLFnal-IRI after initial platinum-based chemotherapy for advanced BTC between January 2016 and August 2020 at the University Hospital Cologne (Cologne, Germany) was performed. A total of 11 patients were identified who met the inclusion criteria. A total of 4 patients (36.4%) were female and the median age was 54 years. The proportion of patients suffering from gallbladder carcinoma, intrahepatic and extrahepatic cholangiocarcinoma was 18.2, 63.6 and 9.1%, respectively. Furthermore, 7 patients (63.6%) received FOLFnal-IRI as their second-, 3 (27.3%) as third- and one (9.1%) as their fourth-line therapy. The disease control rate was 54.5% and 3 grade III toxicities were recorded. Progression-free survival and overall survival (OS) after initiation of FOLFnal-IRI was 5.1 and 12.4 months, respectively. OS after initial diagnosis was 24.7 months. FOLFnal-IRI demonstrated promising antitumor potential with an acceptable safety profile as a subsequent therapy regimen in advanced biliary tract malignancies. Further randomized controlled trials of its value as a treatment option for BTC appear justified.

Abstract
BACKGROUND According to current guidelines, treatment of patients with hepatic oligometastasis in pancreatic cancer is not reflected and systemic chemotherapy is recommended in those patients. Retrospective data suggest beneficial outcomes in patients with hepatic oligometastasis, though prospective data from clinical trials addressing this particular patient group is not available. METHODS In this single arm, phase-2 trial, survival data from patients receiving neoadjuvant chemotherapy followed by R0/R1 resection will be compared to historic data from patients with oligometastatic adenocarcinoma of the pancreas. The clinical trial will focus on a well-defined patient collective with metastatic load limited to the liver as target organ with a maximum of five metastases. The combination of liposomal irinotecan (nal-IRI), oxaliplatin (OX) and 5-fluouracil (5-FU)/folinic acid (FA) (nal-IRI + OX+ 5-FU/FA, NAPOX) was chosen as neoadjuvant chemotherapy; the choice was based on an ongoing clinical study in which NAPOX appeared manageable, with promising anti-tumor activity in first-line treatment of patients with metastatic pancreatic adenocarcinoma. In total 150 patients will be enrolled for this trial with an aim of 55 patients receiving a complete macroscopic synchronous tumor and metastatic resection. DISCUSSION This is the first clinical study to prospectively evaluate the value of multimodality therapy concepts in oligometastatic pancreatic cancer.

Abstract
4078 Background: REG, a multikinase inhibitor, and PEMBRO, an anti-PD-1 mAb, are approved as monotherapies in advanced HCC after progression on sorafenib. This phase 1b dose-finding study investigated first-line REG plus PEMBRO in advanced HCC. Methods: Patients (pts) in the first cohort received a starting REG dose of 120 mg/day orally for 3 weeks (wks) on/1 wk off, which could be escalated (160 mg) or reduced (80 mg) in later cohorts, plus a fixed dose of PEMBRO 200 mg IV every 3 wks. Due to a high dose modification rate in the REG 120 mg cohort, an exploratory REG 80 mg cohort was introduced. Primary objective was safety and tolerability; secondary aims were to assess the maximum tolerated dose (MTD), recommended phase 2 dose, and anti-tumor activity. Results: 35 pts started on REG 120 mg/day and 22 on REG 80 mg/day. Median age was 66 yrs (range 29–81), 84% of pts were male, 70%/30% had ECOG PS 0/1, 26%/74% were BCLC stage B/C, 100% were C–P A, 46% had extrahepatic spread, and 32% had macrovascular invasion. MTD of REG was 120 mg/day. Grade (Gr) 3/4 treatment-emergent adverse events (TEAE) occurred in 86% of pts on REG 120 mg and 50% on REG 80 mg (Table). Most common Gr 3/4 TEAE for REG 120 mg/80 mg were AST increased (23%/9%), lipase increased (20%/5%), ALT increased (17%/9%), and hypertension (17%/9%). TEAE led to REG/PEMBRO dose reductions or interruptions in 71%/57% of pts on REG 120 mg and 59%/45% on REG 80 mg. Median treatment duration (range) was 3.0 months (mo; 0.2–20.5) for REG 120 mg and 3.5 mo (0.03–24.4) for PEMBRO, and 3.5 mo (0.7–10.8) for REG 80 mg and 3.5 mo (0.8–11.3) for PEMBRO. Of 32 evaluable pts on REG 120 mg, 10 (31%) had a partial response (PR) and 18 (56%) had stable disease (SD); disease control rate (DCR) was 88% (RECIST v1.1). Of 22 pts on REG 80 mg, 4 (18%) had a PR and 16 (73%) had SD; DCR was 91%. As of 17 Dec 2020, 16 pts remain on treatment (REG 120 mg n = 5; REG 80 mg n = 11); median follow up was 11.7 mo and 6.9 mo, respectively. REG pharmacokinetic exposure was as expected for 80 mg and 120 mg doses. Flow cytometry analysis of sequential peripheral blood showed changes in subsets of T-cells and monocytes, which may contribute to clinical benefit. Conclusions: First-line REG plus PEMBRO in advanced HCC showed no new safety signals and encouraging anti-tumor activity (DCR ̃90%). The REG 80 mg cohort appeared to have lower rates of dose reductions and interruptions due to TEAE vs REG 120 mg. Efficacy data for the REG 80 mg cohort are preliminary due to short follow-up. Clinical trial information: NCT03347292. [Table: see text]

Nab-paclitaxel plus gemcitabine versus nab-paclitaxel plus gemcitabine followed by FOLFIRINOX induction chemotherapy in locally advanced pancreatic cancer (NEOLAP-AIO-PAK-0113): a multicentre, randomised, phase 2 trial. Lancet Gastroenterol Hepatol 2020; 6:128-138. [PMID: 33338442 DOI: 10.1016/s2468-1253(20)30330-7] [Citation(s) in RCA: 69] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 10/09/2020] [Accepted: 10/09/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND The optimal preoperative treatment for locally advanced pancreatic cancer is unknown. We aimed to compare the efficacy and safety of nab-paclitaxel plus gemcitabine with nab-paclitaxel plus gemcitabine followed by fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) as multidrug induction chemotherapy regimens in locally advanced pancreatic cancer. METHODS In this open-label, multicentre, randomised phase 2 study, done at 28 centres in Germany, eligible patients were adults (aged 18-75 years) with an Eastern Cooperative Oncology Group performance status of 0 or 1 and histologically or cytologically confirmed, treatment-naive locally advanced pancreatic adenocarcinoma, as determined by local multidisciplinary team review. After two cycles of nab-paclitaxel 125 mg/m2 plus gemcitabine 1000 mg/m2 (administered intravenously on days 1, 8, and 15 of each 28-day cycle), patients without progressive disease or unacceptable adverse events were randomly assigned (1:1) to receive either two additional cycles of nab-paclitaxel plus gemcitabine (nab-paclitaxel plus gemcitabine group) or four cycles of sequential FOLFIRINOX (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, irinotecan 180 mg/m2, fluorouracil 400 mg/m2 by intravenous bolus followed by a continuous intravenous infusion of 2400 mg/m2 for 46 h on day 1 of each 14-day cycle; sequential FOLFIRINOX group). Randomisation was done by the clinical research organisation on request of the trial centre using a permuted block design (block size 2 and 4). Patients, investigators, and study team members were not masked to treatment allocation. The primary endpoint was surgical conversion rate (complete macroscopic tumour resection) in the randomised population by intention-to-treat analysis, which was assessed by surgical exploration in all patients with at least stable disease after completion of induction chemotherapy. This trial is registered with ClinicalTrials.gov, NCT02125136. FINDINGS Between Nov 18, 2014, and April 27, 2018, 168 patients were registered and 130 were randomly assigned to either the nab-paclitaxel plus gemcitabine group (64 patients) or the sequential FOLFIRINOX group (66 patients). Surgical exploration after completed induction chemotherapy was done in 40 (63%) of 64 patients in the nab-paclitaxel plus gemcitabine group and 42 (64%) of 66 patients in the sequential FOLFIRINOX group. 23 patients in the nab-paclitaxel plus gemcitabine group and 29 in the sequential FOLFIRINOX group had complete macroscopic tumour resection, yielding a surgical conversion rate of 35·9% (95% CI 24·3-48·9) in the nab-paclitaxel plus gemcitabine group and 43·9% (31·7-56·7) in the sequential FOLFIRINOX group (odds ratio 0·72 [95% CI 0·35-1·45]; p=0·38). At a median follow-up of 24·9 months (95% CI 21·8-27·6), median overall survival was 18·5 months (95% CI 14·4-21·5) in the nab-paclitaxel plus gemcitabine group and 20·7 months (13·9-28·7) in the sequential FOLFIRINOX group (hazard ratio 0·86 [95% CI 0·55-1·36]; p=0·53). All other secondary efficacy endpoints, such as investigator-assessed progression-free survival, radiographic response rate, CA 19-9 response rate, and R0 resection rate, were not significantly different between the two treatment groups except for improved histopathological downstaging in evaluable resection specimens from the sequential FOLFIRINOX group (ypT1/2 stage: 20 [69%] of 29 patients in the sequential FOLFIRINOX group vs four [17%] of 23 patients in the nab-paclitaxel plus gemcitabine group, p=0·0003; ypN0 stage: 15 [52%] of 29 patients in the sequential FOLFIRINOX group vs four [17%] of 23 patients in the nab-paclitaxel plus gemcitabine group, p=0·02). Grade 3 or higher treatment-emergent adverse events during induction chemotherapy occurred in 35 (55%) of 64 patients in nab-paclitaxel plus gemcitabine group and in 35 (53%) of 66 patients in the sequential FOLFIRINOX group. The most common of which were neutropenia (18 [28%] in nab-paclitaxel plus gemcitabine group, 16 [24%] in the sequential FOLFIRINOX group), nausea and vomiting (two [3%] in nab-paclitaxel plus gemcitabine group, eight [12%] in the sequential FOLFIRINOX group), and bile duct obstruction with cholangitis (six [9%] in nab-paclitaxel plus gemcitabine group, seven [11%] in the sequential FOLFIRINOX group). No deaths were caused by treatment-related adverse events during the induction chemotherapy phase. INTERPRETATION Our findings suggest that nab-paclitaxel plus gemcitabine is similarly active and safe as nab-paclitaxel plus gemcitabine followed by FOLFIRINOX as multidrug induction chemotherapy regimens for locally advanced pancreatic cancer. Although conversion to resectability was achieved in about a third of patients, additional evidence is required to determine whether this translates into improved overall survival. FUNDING Celgene.

Microwave ablation enhances tumor-specific immune response in patients with hepatocellular carcinoma. Cancer Immunol Immunother 2020; 70:893-907. [PMID: 33006650 PMCID: PMC7979675 DOI: 10.1007/s00262-020-02734-1] [Citation(s) in RCA: 66] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 09/20/2020] [Indexed: 12/14/2022]
Abstract
Thermal ablative therapies are standard treatments for localized hepatocellular carcinoma (HCC). In addition to local tumor destruction, ablation leads to abscopal effects in distant lesions most likely mediated by an anti-tumor immune response. Although microwave ablation (MWA) is increasingly substituting other ablative techniques, its systemic immunostimulatory effects are poorly studied. We analyzed tumor-specific immune responses in peripheral blood of HCC patients after thermal ablation with regard to T cell responses and disease outcome. While comprehensive flow cytometric analyses in sequential samples of a prospective patient cohort (n = 23) demonstrated only moderate effects of MWA on circulating immune cell subsets, fluorospot analyses of specific T cell responses against seven tumor-associated antigens (TTAs) revealed de-novo or enhanced tumor-specific immune responses in 30% of patients. This anti-tumor immune response was related to tumor control as Interferon-y and Interleukin-5 T cell responses against TAAs were more frequent in patients with a long-time remission (> 1 year) after MWA (7/16) compared to patients suffering from an early relapse (0/13 patients) and presence of tumor-specific T cell response (IFN-y and/or IL-5) was associated to longer progression-free survival (27.5 vs. 10.0 months). Digital image analysis of immunohistochemically stained archival HCC samples (n = 18) of patients receiving combined MWA and resection revealed a superior disease-free survival of patients with high T cell abundance at the time of thermal ablation (37.4 vs. 13.1 months). Our data demonstrates remarkable immune-related effects of MWA in HCC patients and provides additional evidence for a combination of local ablation and immunotherapy in this challenging disease.

Abstract
Metastatic pancreatic cancer has the worst prognosis of all cancers. With nab-Paclitaxel/gemcitabine, FOLFIRINOX, and gemcitabine/erlotinib, several treatment options are available which improve the patient's overall survival. Especially for patients who develop rash under erlotinib treatment can benefit from gemcitabine/erlotinib combination therapy. This non-interventional study (NIS ML21284) investigated the effectiveness and tolerability of gemcitabine/erlotinib therapy in the treatment routine of metastatic pancreatic cancer, in particular, in the context of the occurrence of a rash.Between 2007 and 2010, the treatment data of 433 patients in 98 centres were documented. All parameters recorded were assessed descriptively.Treatment with gemcitabine/erlotinib resulted in both a significant increased median overall survival of the patient subgroup with rash grade ≥ 1 (9.90; 95 % confidence interval [CI], 8.19 to 11.05 vs. 6.48 months; 95 % CI, 5.66 to 7.40, p = 0.0010) and median progression-free survival (5.43, 95 % CI, 4.90 to 6.12 vs. 3.98 months, 95 % CI, 3.52 to 5.03, p = 0.0131). The overall response rate of patients treated with gemcitabine/erlotinib, who had developed rash grade ≥ 1, was 5.9 % higher compared to patients without rash (31.7 % vs. 25.8 %).In conclusion, these results from the daily treatment routine of metastatic pancreatic cancer underline the importance of combined gemcitabine/erlotinib therapy for a subgroup of patients who develop a rash in the course of erlotinib treatment.

Abstract
579 Background: Fibroblast growth factor receptor 2 (FGFR2) alterations occur in 11% of cholangiocarcinomas, 85% of which are fusions. A multicenter, open-label, phase II study is currently evaluating the efficacy of infigratinib, a selective FGFR1–3 tyrosine kinase inhibitor, in patients with previously treated advanced cholangiocarcinoma containing FGFR2 fusions. We report detailed biomarker analyses from this study. Methods: Patients with advanced or metastatic cholangiocarcinoma containing FGFR2 fusions whose disease had progressed following cisplatin- or gemcitabine-based therapy were eligible. Patients received oral infigratinib 125 mg once daily on days 1–21 every 28 days. Comprehensive genomic profiling (CGP) was performed on tumor tissue and cfDNA collected prior to the start of therapy. The primary endpoint was investigator-assessed overall response rate (ORR) [RECIST version 1.1]. Data cut-off (prespecified): August 8, 2018. Trial registration: NCT02150967. Results: At data cut-off, 71 patients with FGFR2 fusions were included (62% women; median age 53 years; 55% received ≥2 prior lines of therapy). Median duration of treatment was 5.5 months. ORR (confirmed and unconfirmed) was 31.0% (95% CI 20.5–43.1%) and confirmed ORR was 26.9% (95% CI 16.8–39.1%). 33 unique FGFR2 fusion genes were identified in 71 enrolled patients. The most common fusion gene partner was BICC1 (32%; 23/71). Pathogenic variants in 9 other druggable genes were identified in 32% of patients (13/37) who underwent CGP. FGFR2 fusions were concordant in 67% (8/12) of patients with tumor tissue and cfDNA at screening. Conclusions: The large assortment of FGFR2 fusion genes identified in this study underscores the diversity of FGFR2 rearrangements that may drive cholangiocarcinoma. Although cfDNA analysis was performed in a minority, these preliminary data suggest that cfDNA analysis may be valuable for the identification of FGFR2 fusions and to study intratumoral heterogeneity. Clinical trial information: NCT02150967.

Abstract
564 Background: REG is a multikinase inhibitor with immunomodulatory activity and PEMBRO is an anti-PD-1 monoclonal antibody. Both are approved as monotherapy for patients (pts) with HCC previously treated with sorafenib. Based on their potential synergistic effects, we conducted a phase 1b study of REG plus PEMBRO for first-line treatment of advanced HCC. Methods: This is an ongoing, open-label, dose-escalation study in pts with advanced HCC who had no prior systemic therapy. In the first cohort, pts received REG 120 mg/day PO for 3 weeks on/1 week off plus PEMBRO 200 mg IV q 3 weeks. In later cohorts, the REG dose could be escalated (160 mg) or reduced (80 mg) based on the modified toxicity probability interval design; the PEMBRO dose is fixed. The primary objective is safety and tolerability. Secondary objectives are to define the maximum tolerated dose (MTD) and recommended phase 2 dose, and to assess antitumor activity. Results: As of August 23, 2019, 29 pts have been treated at the REG 120 mg level. Median age is 65 years (range 32–81); 41%/55% of pts are BCLC stage B/C; 100% are Child–Pugh A; ECOG status 0/1 is 72%/28%. Dose-limiting toxicities occurred in 4/18 evaluable pts: grade (Gr) 3 increased ALT/AST with Gr 2 increased bilirubin (n = 2); Gr 3 rash (n = 2). The MTD of REG in the combination was 120 mg. Most common Gr 3 or 4 treatment-emergent adverse events (TEAEs) are shown (n = 29). There were no Gr 5 TEAEs. 59%/31% of pts had REG/PEMRO-related Gr 3 or 4 TEAEs. Dose modifications (reductions or interruptions) of REG/PEMBRO for drug-related TEAEs occurred in 59%/31% of pts. Of 23 evaluable pts, 7 (30%) had a partial response (PR) and 14 (61%) had stable disease (RECIST v1.1); 1 additional pt had PR by mRECIST. Conclusions: The combination of REG plus PEMBRO for first-line treatment of advanced HCC showed no unexpected safety signals and encouraging antitumor activity. Accrual is continuing at REG 120 mg dose and an expansion cohort evaluating REG 80 mg plus PEMBRO is planned. Clinical trial information: NCT03347292. [Table: see text]

Abstract
Leptomeningeal carcinomatosis is an extremely rare, but devastating complication in pancreatic cancer patients with a poor prognosis despite multimodal treatment. We present a 51-year-old male patient with the very rare condition of leptomeningeal carcinomatosis originating from pancreatic cancer. He presented to our hospital with severe headache and neck stiffness 30 months after systemic chemotherapy. Cerebral and spinal MRI as well as cerebrospinal fluid examination confirmed the diagnosis of leptomeningeal carcinomatosis. The patient responded to gemcitabine plus nab-paclitaxel in terms of elimination of tumor cells from the CSF and concurrent clinical improvement for 3 months. The observed findings suggest that the combination of gemcitabine plus nab-paclitaxel is potentially effective in affected cerebrospinal fluid of pancreatic carcinoma patients.

Proposal for a definition of "Oligometastatic disease in pancreatic cancer". BMC Cancer 2019; 19:1261. [PMID: 31888547 PMCID: PMC6937989 DOI: 10.1186/s12885-019-6448-9] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 12/11/2019] [Indexed: 12/13/2022] Open
Abstract
Background To date, patients with metastasized pancreatic ductal adenocarcinoma (PDAC M1) are regarded as a uniform collective. We hypothesize the existence of oligometastatic disease (OMD): a state of PDAC M1 disease with better tumor biology, limited metastasis, and increased survival. Methods Data of 128 PDAC M1 patients treated at the University of Cologne between 2008 and 2018 was reviewed. Interdependence between clinical parameter was calculated using the Mann-Whitney U-Test. Survival curves were generated using the Kaplan-Meier method and analyzed using the log-rank test. Results Eighty-one (63%) patients had metastases confined to one organ (single organ metastasis, SOG) whereas the remaining 47 (37%) showed multiple metastatic sites (multi-organ metastasis, MOG). Survival analysis revealed a median overall survival (OS) of 12.2 months for SOG vs 4.5 months for MOG (95% CI 5.7–9.8; p < 0.001). We defined limited disease by the presence of ≤4 metastases in liver or lung. Limited disease together with CA 19–9 baseline < 1000 U/ml and response or stable disease after first-line chemotherapy defined OMD. We identified 8 patients with hepatic metastases and 2 with pulmonary metastases matching all OMD criteria. This group of 10 (7.8%) had a median overall survival of 19.4 vs 7.2 months compared to the remaining patients (95% CI 5.7–9.8; p = 0.009). Conclusion We propose a definition of oligometastatic disease in PDAC including anatomical criteria and biological criteria reflecting better tumor biology. The 10 OMD patients (7.8%) survived significantly longer and might even benefit from surgical resection in the future.

Abstract
BACKGROUND Carcinomas of the small bowel are rare tumors usually with dismal prognosis. Most recently, some potentially treatable molecular alterations were described. We emphasize the growing evidence of individualized treatment options in small bowel carcinoma. METHODS We performed a DNA- based multi-gene panel using ultra-deep sequencing analysis (including 14 genes with up to 452 amplicons in total; KRAS, NRAS, HRAS, BRAF, DDR2, ERBB2, KEAP1, NFE2L2, PIK3CA, PTEN, RHOA, BRCA1, BRCA2 and TP53) as well as an RNA-based gene fusion panel including ALK, BRAF, FGFR1, FGFR2, FGFR3, MET, NRG1, NTRK1, NTRK2, NTRK3, RET and ROS1 on eleven formalin fixed and paraffin embedded small bowel carcinomas. Additionally, mismatch-repair-deficiency was analyzed by checking the microsatellite status using the five different mononucleotide markers BAT25, BAT26, NR-21, NR-22 and NR-27 and loss of mismatch repair proteins using four different markers (MLH1, MSH6, MSH2, PMS2). RESULTS In five out of eleven small bowel carcinomas we found potentially treatable genetic alterations. Three patients demonstrated pathogenic (class 5) BRCA1 or BRCA2 mutations - one germline-related in a mixed neuroendocrine-non neuroendocrine neoplasm (MiNEN). Two additional patients revealed an activating ERBB2 mutation or PIK3CA mutation. Furthermore two tumors were highly microsatellite-instable (MSI-high), in one case associated to Lynch-syndrome. We did not find any gene fusions. CONCLUSION Our results underscore, in particular, the relevance of potentially treatable molecular alterations (like ERBB2, BRCA and MSI) in small bowel carcinomas. Further studies are needed to proof the efficacy of these targeted therapies in small bowel carcinomas.

Therapy susceptible germline-related BRCA 1-mutation in a case of metastasized mixed adeno-neuroendocrine carcinoma (MANEC) of the small bowel. BMC Gastroenterol 2018; 18:75.

Abstract
Background Adenocarcinomas or combined adeno-neuroendocrine carcinomas (MANEC) of small bowel usually have a dismal prognosis with limited systemic therapy options. This is the first description of a patient showing a germline-related BRCA1 mutated MANEC of his ileum. The tumor presented a susceptibility to a combined chemotherapy and the PARP1-inhibitor olaparib. Case presentation A 74-year old male patient presented with a metastasized MANEC of his ileum. Due to clinical symptoms his ileum-tumor and the single brain metastasis were removed. We verified the same pathogenic (class 5) BRCA1 mutation in different tumor locations. There was no known personal history of a previous malignant tumor. Nevertheless we identified his BRCA1 mutation as germline-related. A systemic treatment was started including Gemcitabine followed by selective internal radiotherapy (SIRT) to treat liver metastases and in the further course Capecitabine but this treatment finally failed after 9 months and all liver metastases showed progression. The treatment failure was the reason to induce an individualized therapeutic approach using combined chemotherapy of carboplatin, paclitaxel and the Poly (ADP-ribose) polymerase- (PARP)-inhibitor olaparib analogous to the treatment protocol of Oza et al. All liver metastases demonstrated with significant tumor regression after 3 months and could be removed. In his most current follow up from December 2017 (25 months after his primary diagnosis) the patient is in a very good general condition without evidence for further metastases. Conclusion We present first evidence of a therapy susceptible germline-related BRCA1 mutation in small bowel adeno-neuroendocrine carcinoma (MANEC). Our findings offer a personalized treatment option. The germline background was unexpected in a 74-year old man with no previously known tumor burden. We should be aware of the familiar background in tumors of older patients as well.

PICCA study: panitumumab in combination with cisplatin/gemcitabine chemotherapy in KRAS wild-type patients with biliary cancer-a randomised biomarker-driven clinical phase II AIO study. Eur J Cancer 2018; 92:11-19.

Abstract
BACKGROUND Combination chemotherapy has shown benefit in the treatment of biliary cancer and further improvements might be achieved by the addition of a biological agent. We report here the effect of chemotherapy with the monoclonal EGFR antibody panitumumab as therapy for KRAS wild-type biliary cancer. PATIENTS AND METHODS Patients with advanced biliary tract cancer were randomised (2:1) to receive cisplatin 25 mg/m2 and gemcitabine 1000 mg/m2 on day 1 and day 8/q3w with (arm A) or without panitumumab (arm B; 9 mg/kg BW, i.v q3w). The primary end-point was the evaluation of progression-free survival (PFS) at 6 months. Secondary end-points included objective response rate (ORR), overall survival (OS), and toxicity. In addition, a post hoc assessment of genetic alterations was performed. Finally, we performed a meta-analysis of trials with chemotherapy with and without EGFR antibodies. RESULTS Sixty-two patients were randomised in arm A and 28 patients in arm B. Patients received 7 treatment cycles in median (1-35) with a median treatment duration of 4.7 months (141 days, 8-765). PFS rate at 6 months was 54% in patients treated with cisplatin/gemcitabine and panitumumab but was 73% in patients treated with cisplatin/gemcitabine without antibody, respectively. Secondary end-points were an ORR of 45% in treatment arm A compared with 39% receiving treatment B and a median OS of 12.8 months (arm A) and of 20.1 months (arm B), respectively. In contrast to the p53-status, genetic alterations in IDH1/2 were linked to a high response after chemotherapy and prolonged survival. In accordance with our results, the meta-analysis of 12 trials did not reveal a survival advantage for patients treated with EGFR antibodies compared with chemotherapy alone. CONCLUSIONS Panitumumab in combination with chemotherapy does not improve ORR, PFS and OS in patients with KRAS wild-type, advanced biliary cancer. Genetic profiling should be included in CCA trials to identify and validate predictive and prognostic biomarkers. CLINICAL TRIALS NUMBER The trial was registered with NCT01320254.

Abstract
348 Background: Although there is a strong rationale for downstaging non-resectable pancreatic ductal adenocarcinoma (PDAC) for secondary resections by multi-agent chemotherapy, evidence from prospective randomized studies is missing. Methods: This prospective, randomized, open-label, phase II study aims to assess the activity, safety and feasibility of nab-paclitaxel/gemcitabine (nPG)- and FOLFIRINOX-based induction chemotherapy for patients (pts) with non-resectable PDAC. After two cycles of nPG pts are randomly allocated to receive either two additional cycles of nPG (arm A) or four cycles of FOLFIRINOX (arm B). Secondary resectability is assessed by exploratory laparotomy in all pts with at least stable disease (SD) after induction chemotherapy. The primary endpoint is to compare secondary complete macroscopic resection rates (R0/R1) in both arms. Results: We report the results of a planned interim (futility) analysis for efficacy data after at least 50 patients had completed induction chemotherapy and are evaluable for secondary surgical resection. Of pts who underwent randomization 42 pts were allocated to arm A and 44 pts to arm B, respectively. Disease control rate (DCR) after randomization was 93% in arm A and 89% in arm B. Explorative laparotomy was performed in 55% of randomized pts in arm A and 48% in arm B. Complete macroscopic resection (R0/R1) rate of randomized pts was 24% in arm A and 29% in arm B. For pts who received surgical exploration by laparotomy after completion of induction chemotherapy (n = 44) the complete macroscopic resection (R0/R1) rate was 43% in arm A and 62% in arm B. No new safety signals were identified thus far. Conclusions: nPG- and FOLFIRINOX-based induction chemotherapy approach revealed both effective and feasible in pts with LAPC supporting completion of patient recruitment in this trial. Interim results suggest promising secondary resection rates after multi-agent chemotherapy, especially when secondary resectability is assessed by surgical exploration. Clinical trial information: NCT02125136.

Abstract
Purpose Gemcitabine is standard of care in the adjuvant treatment of resectable pancreatic ductal adenocarcinoma (PDAC). The epidermal growth factor receptor tyrosine kinase inhibitor erlotinib in combination with gemcitabine has shown efficacy in the treatment of advanced PDAC and was considered to improve survival in patients with primarily resectable PDAC after R0 resection. Patients and Methods In an open-label, multicenter trial, patients were randomly assigned to one of two study arms: gemcitabine 1,000 mg/m2 days 1, 8, 15, every 4 weeks plus erlotinib 100 mg once per day (GemErlo) or gemcitabine (Gem) alone for six cycles. The primary end point of the study was to improve disease-free survival (DFS) from 14 to 18 months by adding erlotinib to gemcitabine. Results In all, 436 patients were randomly assigned at 57 study centers between April 2008 and July 2013. A total of 361 instances (83%) of disease recurrence were observed after a median follow-up of 54 months. Median treatment duration was 22 weeks in both arms. There was no difference in median DFS (GemErlo 11.4 months; Gem 11.4 months) or median overall survival (GemErlo 24.5 months; Gem 26.5 months). There was a trend toward long-term survival in favor of GemErlo (estimated survival after 1, 2, and 5 years for GemErlo was 77%, 53%, and 25% v 79%, 54%, and 20% for Gem, respectively). The occurrence or the grade of rash was not associated with a better survival in the GemErlo arm. Conclusion To the best of our knowledge, CONKO-005 is the first study to investigate the combination of chemotherapy and a targeted therapy in the adjuvant treatment of PDAC. GemErlo for 24 weeks did not improve DFS or overall survival over Gem.

Abstract
Esophageal cancer is the eighth most common malignant tumor worldwide, and the number of incidences of esophageal adenocarcinoma is increasing in the Western world. Despite improvements in perioperative treatment, the overall survival rate of patients with esophageal adenocarcinoma remains poor. Breast cancer type 1 susceptibility protein (BRCA1)-associated protein (BAP1) is located on chromosome 3p21, and it is an enzyme with ubiquitin carboxyl hydrolase activity that regulates cell growth. It interacts with BRCA1, and the nuclear localization of BAP1 is required for its tumor suppressor function. BAP1 is frequently mutated in uveal melanomas, malignant mesothelioma and several carcinomas, including a subtype of renal cell carcinoma, intrahepatic cholangiocarcinoma and squamous cell carcinoma of the esophagus. Furthermore, several germline-associated mutations of tumors have been described (BAP1 hereditary cancer syndrome). However, the importance and frequency of BAP1 alterations in adenocarcinoma of the esophagus remain to be elucidated. In the present study, tissue microarrays of 332 resected adenocarcinomas (including a few cases of concomitant Barrett dysplasia) of the esophagus were constructed. The tumor tissue was analyzed using immunohistochemistry to investigate the levels of BAP1 expression. Fibroblasts or inflammatory cells served as an internal positive control. Three adenocarcinomas revealed nuclear loss of BAP1 (0.9%). One case with concomitant Barrett dysplasia also exhibited a loss of BAP1. Of the resected adenocarcinomas, 329 of them exhibited an intact and uniform strong nuclear staining pattern. To the best of our knowledge, this is the first description of BAP1 deficiency in adenocarcinomas of the esophagus. Furthermore, it has been demonstrated that BAP1 loss is possibly an early event in esophageal adenocarcinoma. These results warrant further functional and clinical evaluation.

Abstract
Adenocarcinoma of the pancreas has a poor prognosis. At present, no relevant personalized targets have been identified. Sequencing studies have implicated gene alterations of disruptor of telomeric silencing 1 like histone lysine methyltransferase (DOT1L) in pancreatic adenocarcinoma. DOT1L is part of the histone modification system and catalyzes methylation of H3K79, which is crucial in cell signaling and DNA damage repair. DOT1L is considered to be a target of therapy in mixed lineage leukemia gene-deficient leukemia cases and a potential target in breast carcinoma. The frequencies and importance of DOT1L copy-number variations and their specific correlation with protein expression in adenocarcinoma of the pancreas have yet to be investigated. In the present study, tissue microarrays of 230 resected pancreatic adenocarcinoma cases were constructed. The tumor tissue was analyzed using fluorescence in situ hybridization (FISH) and immunohistochemistry. In total, 10/225 carcinoma cases (4.4%) analyzed by immunohistochemistry demonstrated intense nuclear protein expression of DOT1L and in 9/224 tumors analyzed using FISH (4.0%), copy-number variations (CNV) were detectable. No DOT1L amplification was detected in the carcinoma cohort. To the best of our knowledge, the present study describes for the first time the frequency of CNV of DOT1L using the gold standard fluorescence in situ hybridization (FISH) and their specific correlation to the protein expression in adenocarcinomas of the pancreas. Although the positive cases by immunohistochemistry and copy-number variations by FISH were not congruent with each other, the data suggest a potential role for DOT1L in a small subset of pancreatic cancer cases. The significance of the two analysis methods concerning their druggability in pancreatic adenocarcinoma requires further studies.

Abstract
BACKGROUND Drug-induced skin toxicity may correlate with treatment efficacy in cancer patients receiving chemotherapy or biological agents. The correlation of the capecitabine-associated hand-foot skin reaction (HFS) on outcome parameters in pancreatic cancer (PC) has not yet been investigated. METHODS Within the multicentre phase III AIO-PK0104 trial, patients with confirmed advanced PC were randomly assigned to first-line treatment with either capecitabine plus erlotinib (150 mg/day, arm A) or gemcitabine plus erlotinib (150 mg/day, arm B). A cross-over to either gemcitabine (arm A) or capecitabine (arm B) was performed after failure of the first-line regimen. Data on skin toxicity were correlated with efficacy study endpoints using uni- and multivariate analyses. To control for guarantee-time bias (GTB), we focused on subgroup analyses of patients who had completed two and three or more treatment cycles. RESULTS Of 281 randomised patients, skin toxicity data were available for 255 patients. Median time to capecitabine-attributed HFS was two cycles, 36 of 47 (77%) HFS events had been observed by the end of treatment cycle three. Considering HFS during first-line treatment in 101 patients treated with capecitabine for at least two cycles within the capecitabine plus erlotinib arm, time to treatment failure after first- and second-line therapy (TTF2) and overall survival (OS) both were significantly prolonged for the 44 patients (44%) with HFS compared to 57 patients without HFS (56%) (TTF2: 7.8 vs. 3.8 months, HR 0.50, p = 0.001; OS: 10.4 vs. 5.9 months, HR 0.55, p = 0.005). A subgroup analysis of 70 patients on treatment with capecitabine for at least three cycles showed similar results (TTF2: 8.3 vs. 4.4 months, HR 0.53, p = 0.010; OS: 10.4 vs. 6.7 months, HR 0.62, p = 0.056). CONCLUSION The present subgroup analysis from AIO-PK0104 suggests that HFS may serve as an independent clinical predictor for treatment outcome in capecitabine-treated patients with advanced PC.

Abstract
BACKGROUND Patients with ileostomies regularly suffer from short bowel syndrome or high volume output associated with loss of absorptive surface and subsequent impairment of absorption for drugs and different nutrients resulting in electrolyte and fluid balance disorders as well as renal insufficiency. Adaptation of these fundamental functions of the gut with adequate fluid uptake, absorption of sufficient different nutrients and vitamins represents a major challenge to rehabilitate these patients shortly after surgery. Patients with ileostomy often develop metabolic acidosis with normal anion gap. In our retrospective study we would like to draw attention to these metabolic disorders in patients with ileostomy in comparison to patients with colostomy and patients undergoing gastrectomy for gastric cancer. METHODS In the period from 2005 to 2012 we examined 164 patients with ileostomy in our rehabilitation clinic, 109 patients with colostomy and 193 patients after surgery for gastric cancer of the possible presence of metabolic acidosis by using capillary blood gas analysis (metabolic acidosis was anticipated, if base excess was ≤- 3,0 mmol/l). Patients are treated as inpatients both in early stage and for follow-up rehabilitation. The length of time in our rehabilitation clinic lies in between 24-28 days. On the basis of random samples we tested blood samples in 19 patients with ileostomy in succession for ferritin, folic acid, zinc, selenium and vitamin B12. Statistical analysis comprised the classical intervals (mean and standard deviation, range and T-test for dependent and independent samples). RESULTS In total we tested 164 inpatients with ileostomy in our rehabilitation clinic (median age 67.4 years, range 19-79 years). Surgery for ileostomy took place about 1.4 months on average ago (range ¼-56 months). 60 (36.5%) inpatients suffered from metabolic acidosis often combined with renal insufficiency. Supportive therapy intravenously administered in 10 patients and sodium bicarbonate given by mouth in 40 patients significantly improved metabolic acid (base excess improved on average from -7.2 to -3.2 mmol/l, p<0.00138) and renal function calculated on the basis of serum creatinine (serum creatinine decreased from 1.49 on average to 1.34 mg/dl, p<0.04039). Body weight remained constant over the whole period on average with 74 kg. Diuretics did not show any influence on the base excess. In 19 patients with ileostomy who did not take any kind of supplements, among the parameters tested were a high percentage of zinc (9 of 19 patients, 47%) and selenium deficiency (13 of 19 patients, 68%). 50 patients with ileostomy were younger than 65 years of age and thus in the working age population. In the group of patients after gastrectomy because of gastric cancer (n=193, median age 69.1 years, range 36-82 years), surgery for gastrectomy took place about 1.8 months on average ago and in this group only 14 patients (7%) showed metabolic acidosis. In the group of patients with colostomy (n=109, median age 69.5 years, range 39-82 years), surgery for colostomy took place about 2.1 months on average ago and in this group only 6 patients (5.5%) suffered from metabolic acidosis. CONCLUSION Medical rehabilitation is indicated for patients with enterostoma. Acceptance of the enterostoma by the patient himself, psychological stabilization, achievement of self-sufficiency in stoma care, improvement of physical abilities and finally being fit for full or limited employment are the most important objectives in rehabilitation medicine. Metabolic acidosis was often found in patients with ileostomy and was an important clinical appearance. Blood gas analysis is recommended to verify metabolic acidosis and if confirmed sodium bicarbonate and in cases of high volume output salt-depleting ileostomy additionally intravenous fluid support should be offered controlling body weight in the follow-up. As could be shown by our analysis patients with ileostomy should also be tested for zinc and selenium deficiency.

Clinical management of chronic hepatitis B infection: results from a registry at a German tertiary referral center. Infection 2015; 43:153-62. [PMID: 25701223 DOI: 10.1007/s15010-015-0751-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Accepted: 02/13/2015] [Indexed: 12/18/2022]
Abstract
PURPOSE We studied a cohort of adult patients with chronic hepatitis B (CHB) infection, followed at a tertiary referral liver center in Germany over 12.5 years to analyze the clinical features and impact of management on disease progression and survival of CHB patients in general and of those with CHB and HCC in particular. METHODS We retrospectively evaluated the medical records of 242 adult (age ≥ 18 years) patients. CHB was defined as positive hepatitis B surface antigen (HBsAg) and/or HBV-DNA levels >10 IU/mL for at least 6 months. Patient demographics, HBV markers, antiviral treatment, laboratory parameters, liver imaging and histology were recorded for each visit. HCC patients were divided into two groups and separately analyzed (group 1: n = 24, HCC at first visit and group 2: n = 11, HCC during surveillance). RESULTS The mean age was 44 years in CHB patients without HCC (63% male) and about 59 years in patients with HCC (77% male). Antiviral therapy was given to 59% of patients without HCC compared to only 25% in group 1 and 18% in group 2 with comparable median HBV DNA levels of approximately 36,000 IU/mL. There was no statistically significant difference concerning the HCC stages (Milan, UCSF, BCLC) at first diagnosis. Five-year survival was 19% in group 1 vs. 64% in group 2 (p = 0.019), with LTx performed in 12 vs. 45%, respectively. CONCLUSION Surveillance of CHB patients did not result in early stage detection of HCC but in a higher likelihood to receive potentially curative treatments.

Abstract
LBA173 Background: TGF-β signaling is associated with HCC progression in moderate to poorly differentiated tumors overexpressing alpha-fetoprotein (AFP) levels. We report here the safety, antitumor activity, and overall survival (OS) in HCC patients with elevated AFP treated with LY. Methods: Patients with advanced HCC who progressed on sorafenib (SF) or are ineligible to receive SF, advanced Child-Pugh A/B7 HCC, AFP ≥1.5x ULN, ECOG PS ≤1, measurable disease (RECIST 1.1), and ≤1 prior systemic regimen were eligible. LY was administered as intermittent dosing of 14 days on/off (28 days=1 cycle). Patients were randomized to either 160 mg/day (Arm A) or 300 mg/day (Arm B) LY. Primary endpoints were time-to-progression (TTP) and biomarker changes (serum AFP, TGF-β and E-cadherin) for each dose. AFP responders were defined as >20% decline from baseline. Secondary endpoints included toxicity (CTCAE, V 4.0) and pharmacokinetics (PK). Available data from interims are presented. Results: 109 patients were enrolled (Arm A=37; B=72). Baseline characteristics were (Arm A/B): median age 61/63 years; PS=0, 60%/53%; Child-Pugh A 97%/88%; etiology: hepatitis C 30%/38%, hepatitis B 27%/24%, alcohol 24%/25%. Overall, 78%/83% of patients had received prior SF; 57%/53% had AFP >400 ng/mL. Median TTP was 12.0 weeks (90% CI: 6.6, 12.6) in the overall population (Arm A/B, 12.1/10.0 weeks). In SF-naive patients, TTP was 18.3 weeks (90% CI: 6.6-42.4). TTP was higher in the non-alcohol compared to alcohol-only etiology group (median 12.1 vs. 6.1 weeks). Median baseline serum TGF-β1 was 3.4 ng/mL (range: 1.4-3.7) and E-cadherin was 6.1 mg/mL (range: 1.9-17.3). AFP decline of >20% occurred in 24% of patients. Based on the latest interim, median OS was 36 weeks. In AFP responders, median OS was 93.1 weeks vs 29.6 weeks in non AFP responders (Log Rank p=0.0006). Four patients discontinued treatment due to AEs. Most common grade 3/4 related AEs were: neutropenia (n=3), fatigue (n=2), and anemia (n=3). Preliminary PK analysis (n=51) demonstrated moderate interpatient exposure variability (42%). Conclusions: Based on the manageable toxicity profile, the evidence for biomarker responses, analysis of the aggregate PK/PD data, the 300 mg/day dose was chosen for future studies in HCC. Both TTP and overall survival in AFP responding patients is promising.

Abstract
Abstract
Background: TGF-β signaling is associated with HCC progression in moderate to poorly differentiated tumors. LY is a TGF-β receptor I kinase inhibitor currently in clinical testing in glioblastoma (GBM), hepatocellular, and pancreatic cancer. We report here the safety and PK/PD profile of LY in HCC patients. Methods: Patients with advanced HCC who progressed on or were ineligible to receive sorafenib (SF), advanced Child-Pugh A/B7 HCC, ECOG PS ≤1, measurable disease (RECIST 1.1), and ≤1 prior systemic regimen were eligible. LY was administered as intermittent dosing of 14 days on/14 days off (28 days = 1 cycle). Patients received either 160 mg/day or 300 mg/day. PK data were used to build a population PK model for HCC patients. This population PK model guided appropriate sampling and identification of potential demographic covariates. PD analysis included serum alpha-fetoprotein (AFP). AFP response was defined as at least 20% decrease. Results: Among 148 patients enrolled, 137 patients were evaluable for PK. There was dose-proportional increase in exposure (AUC0-∞ = 3.8 mg*h/L for 160 mg and AUC0-∞ = 7.0 mg*h/L for 300 mg dose). There were higher exposures in HCC patients than previously observed for exposures in GBM patients (AUC0-∞ = 2.1 mg*h/L for 160 mg and AUC0-∞ = 3.7 mg*h/L for 300mg dose)1. PK data suggested that total oral clearance (CL/F = 25.4 L/hr) of LY in HCC patients is lower than previously reported clearance in GBM patients (CL/F = 38.4 L/hr). Moderate between-patient variability on exposure was observed in HCC patients similar to GBM patients. LY appears to be fully eliminated at the end of the 14-days-off period of a cycle. Administration of 300 mg/day to patients with HCC may result in higher exposures compared to patients with GBM. These increased exposures did not result in increase of toxicities. Eight patients discontinued treatment due to a possibly drug-related adverse event (AE). LY was well tolerated, most adverse events being grade1-2. Most common grade 3/4 possibly drug-related AEs in patients were: neutropenia (n = 3), anemia (n = 3) and fatigue (n = 2). Thirty-nine percent of 69 patients with HCC who had baseline AFP of >200 ng/mL had AFP response. The median time-to-progression of responders vs. non-responders was 18 vs. 10 weeks (p<0.01), respectively. Conclusion: Clearance of LY in HCC patients with Child Pugh A/B7 liver function is lower than in GBM patients. LY had manageable safety profile in HCC patients and was associated with AFP responses.

Abstract
4118 Background: TGF-ß signaling is associated with HCC progression in moderate to poorly differentiated tumors overexpressing alpha-fetoprotein (AFP) levels. We report here the safety and antitumor activity of LY in HCC patients with elevated AFP in this ongoing study. Methods: Patients with advanced HCC who progressed on sorafenib (SF) or are ineligible to receive SF, advanced Child-Pugh A/B7 HCC, AFP ≥1.5x ULN, ECOG PS ≤1, measurable disease (RECIST 1.1), and ≤1 prior systemic regimen were eligible. LY was administered as intermittent dosing of 14 days on/14 days off (28 days =1 cycle). Patients were randomized to either 160 mg/day (Arm A) or 300 mg/day (Arm B) LY. Primary endpoints were time-to-progression (TTP) and biomarker changes (serum AFP, TGF-ß and E-cadherin) for each dose. Secondary endpoints included toxicity (CTCAE, V 4.0) and pharmacokinetics (PK). Results: 106 patients were enrolled (Arm A=37; B=69), including 92% non-Asians. Baseline characteristics were (Arm A/B): median age 61/66 years; PS=0 60/51%; Child-Pugh A 97/86%; etiology: hepatitis C 30/33%, hepatitis B 24/25%, alcohol 22/22%. Overall, 78/83% of patients had received prior SF; 64/58% of patients had AFP ≥400 ng/mL. Median TTP was 12.0 weeks (90% CI: 7.1, 12.6) in the overall population (Arm A, 12.6 weeks; Arm B, 10.9 weeks). In SF-naïve patients, TTP was 18.3 weeks (90% CI: 6.3-non-estimable). TTP was higher in the non-alcohol compared to alcohol-only etiology group (median 12.1 vs. 6.1 weeks). Median baseline serum TGF-ß1 was 3.4 ng/mL (range: 1.4-3.7) and E-cadherin was 6.1 mg/mL (range: 1.9-17.3). AFP decline of >25% occurred in 21/106 patients (20%). Four patients discontinued treatment due to a drug-related AE. Most common grade 3/4 related AEs in patients were: neutropenia (n=3), GI bleeding (n=2), fatigue (n=2), and anemia (n=2). Preliminary PK analysis (51 patients) demonstrated moderate interpatient exposure variability (42%). Conclusions: Based on the manageable toxicity profile, the evidence for biomarker/TTP responses, and an analysis of the aggregate PK/PD data, the 300 mg/day dose was chosen for future studies in HCC. Clinical trial information: NCT01246986.
