Changing treatment landscape associated with improved survival in advanced hepatocellular carcinoma: a nationwide, population-based study.

BACKGROUND AND AIMS: The treatment of hepatocellular carcinoma (HCC) is undergoing a historic transformation with the approval of several new systemic therapies in the last few years. This study aimed to examine the impact of this changing landscape on survival and costs in a Western nationwide, real-world cohort. METHODS: A nationwide representative claims database (InGef) was screened for HCC cases between 2015 and 2020. Survival in an era with only sorafenib (period A, January 2015 to July 2018) and after approval of lenvatinib and other systemic treatments (period B, August 2018 to December 2020) was analysed. Health care costs were assessed. RESULTS: We identified 2876 individuals with HCC in the study period. The proportion of patients receiving systemic therapy increased significantly over time, from 11.8% in 2015 to 15.1% in 2020 (p < 0.0001). The median overall survival in period B was 6.5 months (95% confidence interval [CI]: 4.9-8.9) and in period A was 5.3 months (95% CI: 4.5-6.3; p = 0.046). In period B, the median overall survival with lenvatinib was 9.7 months (95% CI: 6.3-18.4) versus 4.8 months with sorafenib (95% CI: 4.0-7.1, p = 0.008). Costs for prescription drugs per patient increased from €6150 in 2015 to €9049 in 2020 (p < 0.0001), and costs for outpatient care per patient increased from €1646 to €2149 (p = 0.0240). CONCLUSION: The approval of new systemic therapies resulted in a survival benefit in patients with HCC. The magnitude of the effect is modest and associated with a moderate increase in health costs.

Second Cancer After Additive Chemotherapy in Patients With Colon Cancer.

BACKGROUND: Additive chemotherapeutic treatment of UICC-stage -III / IV colon cancer with fluorouracil, leucovorin and oxaliplatin is widely accepted as current standard of treatment after R0-resection. However, as patients.. survival is increasing, long-term side effects of chemotherapeutic agents such as second cancer development are becoming increasingly important. PATIENTS: We therefore investigated a total of 2 856 Patients with UICC-stage III / IV colon cancer, 223 of whom (7.8%) had developed a subsequent second cancer. RESULTS: Median follow-up was 73.2 months (range 209.9 months, 95%-CI 69.8-76.9). Most frequent second cancers were prostate cancer (18.4%), colon cancer (16.1%), breast cancers (8.1%), lung cancer (8.1%), rectal cancer (4.9%) and uterine cancer (4.9%). However, in comparison to non-treated patients this did not represent a significantly increased risk for subsequent second cancer in patients after treatment with additive chemotherapy. Of interest, our data suggest a significantly decreased second cancer rate in patients treated with FOLFOX compared to FUFOL for additive treatment. CONCLUSIONS: Second cancer development was not increased after additive chemotherapy for colon cancer, which is a novel aspect in the ongoing discussions on reduction of adjuvant treatment to 3 months or treatment of lymph node negative patients. Novelty and Impact Statement To our knowledge, this is the first population-based study analyzing second cancer development after additive chemotherapy in patients with UICC III-IV colon cancer. The results have an important impact on the surveillance and long-term follow-up of cancer patients.

Co-Medication and Nutrition in Hepatocellular Carcinoma: Potentially Preventative Strategies in Hepatocellular Carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide, with about 841,000 new cases and 782,000 deaths annually. Given the clearly defined population at risk, mostly patients with liver cirrhosis, prevention of HCC could be highly effective. SUMMARY: Besides regular ultrasound surveillance, numerous publications have suggested protective effects of diverse drugs and nutrients. However, none of those preventive options has made it into clinical routine or practice guidelines. We therefore summarize the current status of preventive effects of drugs such as statins, acetylsalicylic acid (ASA), and metformin, but also dietary aspects and nutrients such as coffee, tea, and vitamin D supplementation. A successful implementation of some of these strategies may potentially lead to improved prevention of HCC development in patients with liver cirrhosis. Key Messages: Accumulating data suggest that particularly ASA, antidiabetic therapies, and statins may substantially decrease HCC incidence in patients at risk.

Applicability of scoring systems predicting outcome of transarterial chemoembolization for hepatocellular carcinoma.

PURPOSE: Several scoring systems have been proposed to predict the outcome of transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). However, the application of these scores to a bridging to transplant setting is poorly validated. Evaluation of the applicability of prognostic scores for patients undergoing TACE in palliative intention vs. bridging therapy to liver transplantation (LT) is necessary. METHODS: Between 2008 and 2017, 148 patients with HCC received 492 completed TACE procedures (158 for bridging to transplant; 334 TACE procedures in palliative treatment intention at our center and were analyzed retrospectively. Scores (ART, CLIP, ALBI, APRI, SNACOR, HAP, STATE score, Child-Pugh, MELD, Okuda and BCLC) were calculated and evaluated for prediction of overall survival. ROC analysis was performed to assess prediction of 3-year survival and treatment discontinuation. RESULTS: In patients receiving TACE in palliative intention most scores predicted OS in univariate analysis but only mSNACOR score (p = 0.006), State score (p < 0.001) and Child-Pugh score (p < 0.001) revealed statistical significance in the multivariate analysis. In the bridging to LT cohort only the BCLC score revealed statistical significance (p = 0.002). CONCLUSIONS: Clinical usability of suggested scoring systems for TACE might be limited depending on the individual patient cohorts and the indication. Especially in patients receiving TACE as bridging to LT none of the scores showed sufficiently applicability. In our study Child-Pugh score, STATE score and mSNACOR score showed the best performance assessing OS in patients with TACE as palliative therapy.

Pharmacological treatment of hepatocellular carcinoma with cavoatrial tumor thrombus - case series and literature review.

Hepatocellular carcinomas (HCC) that extend into the vena cava and the right atrium have a poor prognosis. Surgical approaches including partial hepatectomy and thrombectomy are the most frequently reported treatment options. However, most patients with advanced HCC are not eligible for complex surgical interventions due to reduced liver function, comorbidities, and metastases. At the same time, systemic treatment options of HCC have expanded in recent years. Here, we report 3 cases of patients with advanced HCC who developed a cavoatrial tumor thrombus (CATT) after initial surgical or interventional therapy. The patients were consequently treated with sorafenib or nivolumab. In all cases, the tumor responded to systemic treatment with disease stabilization or partial regression. Overall survival after diagnosis of CATT was 3 and 17 months for sorafenib and 7 + months for nivolumab. Compared to survival rates of alternative treatment options, systemic therapies demonstrated comparable outcomes. In summary, pharmacotherapy is an efficient and well worth option to treat patients with HCC and CATT and should be an integral part of a multimodal therapy concept.

Analysis of Radiological Case Presentations and their Impact on Therapy and Treatment Concepts in Internal Medicine.

Purpose Evaluation of clinical impact regarding diagnostic and therapeutic changes influenced by interdisciplinary radiological case presentations. Materials and Methods Prospective evaluation of radiological-gastrointestinal clinical case conferences over a 1-year period at a tertiary care center. We documented the preparation (phase 1) and clinical case conference (phase 2) regarding their impact on the radiology report and further diagnostic work-up and therapy. Results 1067 examinations were evaluated in 69 clinical case conferences including 487 cases. We calculated a mean time of 35.8 minutes per conference with 5.1 minutes per case for preparation. During phase 1, major changes compared to the previous report were found in 1.2 % of cases, and no change was found in 91.4 % of cases. In phase 2 an additional relevant finding was found in 0.6 % of cases, while there was no major change to the reports in 99 % of cases. We recommended further radiological diagnostic workup in 9 % of cases and interventional radiological examination in 2.7 % of cases, while no change was documented in 83.2 %. Further radiological or surgical therapy was recommended in 7 % and 6.8 % of cases, respectively. There was no change in therapy in 78.5 % of cases. Conclusion The analysis of an interdisciplinary radiological case presentation in internal medicine shows that the case discussion with the radiologist results in a change in patient management in 37.3 % of cases (16.8 % diagnosis, 21.5 % therapy). Overall, interdisciplinary radiological clinical case conferences help to improve the management and quality of patient care. Our data support the broad implementation of radiological clinical case conferences. Key Points · The second opinion obtained during the preparation of a radiological case presentation does not change the written report in most cases.. · "Talking radiology" in radiological case presentations results in a significant change in patient management in over ⅓ of all cases.. · In radiological clinical case conferences an experienced radiologist can initiate diagnostic and interventional radiological methods that can be correctly implemented in therapeutic pathways.. · "Talking radiology" improves the quality of therapy and patient care..

Benefit of adjuvant chemotherapy in patients with T4 UICC II colon cancer.

BACKGROUND: Colorectal cancer is the third most common cancer and a major cause of morbidity and mortality worldwide. Adjuvant chemotherapy is considered the standard of care in patients with UICC stage III colon cancer after R0 resection. Adjuvant therapy was not shown to be beneficial in patients with UICC stage II colon cancer. However, there is an ongoing discussion as to whether adjuvant chemotherapy may be beneficial for a subgroup of UICC II patients in a "high-risk situation" (such as T4). METHODS: We investigated a Bavarian population-based (2.1 million inhabitants) cohort of 1937 patients with UICC II CRC treated between 2002 and 2012 in regard of the benefit of adjuvant chemotherapy for large (T4) tumors. Patients older than 80 years of age were excluded. Of 1937 patients, 240 had a T4 tumor (12%); 77 of all T4 patients received postoperative chemotherapy (33%). Kaplan-Meier analysis and Cox regression models were used for survival analyses. RESULTS: Patients with a T4 tumor who received postoperative chemotherapy had a highly significant survival benefit in respect of overall survival (p<0.001) and recurrence-free survival (p=0.008). However, no difference was observed between oxaliplatin-containing and non-oxaliplatin-containing treatment regimens. G2 and G3 tumors were found to particularly benefit from adjuvant treatment. Chemotherapy, age at diagnosis, and tumor grading remained independent risk factors in the multivariate cox regression analysis. CONCLUSION: Our retrospective study demonstrated the significant benefit of adjuvant chemotherapy in the T4 subgroup of patients with UICC II colon cancer. Our data suggest that adjuvant chemotherapy should be seriously considered in these patients.

Metabolomic tissue signature in human non-alcoholic fatty liver disease identifies protective candidate metabolites.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder in industrialized countries, yet its pathophysiology is incompletely understood. Small-molecule metabolite screens may offer new insights into disease mechanisms and reveal new treatment targets. METHODS: Discovery (N = 33) and replication (N = 66) of liver biopsies spanning the range from normal liver histology to non-alcoholic steatohepatitis (NASH) were ascertained ensuring rapid freezing under 30 s in patients. 252 metabolites were assessed using GC/MS. Replicated metabolites were evaluated in a murine high-fat diet model of NAFLD. RESULTS: In a two-stage metabolic screening, hydroquinone (HQ, p(combined) = 3.0 × 10(-4)) and nicotinic acid (NA, p(combined) = 3.9 × 10(-9)) were inversely correlated with histological NAFLD severity. A murine high-fat diet model of NAFLD demonstrated a protective effect of these two substances against NAFLD: Supplementation with 1% HQ reduced only liver steatosis, whereas 0.6% NA reduced both liver fat content and serum transaminase levels and induced a complex regulatory network of genes linked to NALFD pathogenesis in a global expression pathway analysis. Human nutritional intake of NA equivalent was also consistent with a protective effect of NA against NASH progression. CONCLUSION: This first small-molecular screen of human liver tissue identified two replicated protective metabolites. Either the use of NA or targeting its regulatory pathways might be explored to treat or prevent human NAFLD.

Safety and efficacy of sorafenib in patients with advanced hepatocellular carcinoma in consideration of concomitant stage of liver cirrhosis.

GOALS AND BACKGROUND: The multikinase inhibitor sorafenib provides survival benefit for patients with advanced hepatocellular carcinoma (HCC) and liver cirrhosis (LCI) Child-Pugh A. We report our experiences with sorafenib in advanced HCC, particularly in patients with LCI Child-Pugh B/C, where only limited data are available in regard to safety and efficacy of sorafenib. METHODS: Thirty-four patients with advanced HCC were treated with sorafenib regardless of liver function and prior anticancer therapy. Adverse events (AEs) were graded using Common Toxicity Criteria version 3.0, tumor response was assessed according to Response Evaluation Criteria in Solid Tumors. RESULTS: Fifteen patients presented without LCI or with LCI Child- Pugh A, 15/4 patients had LCI Child-Pugh B/C. Barcelona Clinic Liver Cancer stage was B/C/D in 4/22/8 patients. During treatment period (median 2.2 mo), therapy was discontinued in 61.8% of patients due to tumor progression (32.3%), death (17.6%), AEs (8.8%), or noncompliance (2.9%). Most common grade 3/4 AEs included liver dysfunction (23.5%), diarrhea (14.7%), increased lipase (8.8%), fatigue (8.8%), and hand-foot skin reaction (5.9%). Worsening liver dysfunction/failure was more frequent (P=0.036) in patients with LCI Child-Pugh B/C compared with patients with maintained liver function (no LCI/LCI Child-Pugh A). Median overall survival was 7.2 months for patients with maintained liver function versus 3.3/3.4 months for patients with LCI Child-Pugh B/C. CONCLUSIONS: These data do not support the use of sorafenib in patients with LCI Child-Pugh C, and patients with LCI Child-Pugh B should be treated with caution until larger trials provide more safety data and a clinically relevant survival benefit under sorafenib therapy.

New chemotherapeutic strategies in colorectal cancer.

Since colorectal cancer is the second most prevalent cancer worldwide, its treatment remains a major challenge for researchers, gastroenterologists and oncologists. Despite curative resections, half of all patients diagnosed with colorectal cancer die because of their underlying disease. Integral chemotherapeutic components of standard regimens are 5-fluorouracil (5-FU), its modulation by folinic acid and irinotecan or oxaliplatin. All these drugs sequentially given have results in terms of median overall survival of more than 20 months in the palliative treatment of advanced colorectal cancer. Oral fluoropyrimidines, currently under clinical investigation, are likely to substitute continuous 5-FU. Inhibitors of growth factor receptors or their signaling may further prolong disease-free and overall survival rates. Preliminary evidence exists that improved adjuvant and neoadjuvant chemotherapy strategies may further improve the prognosis, mainly because more patients are able to go for primary or secondary surgery with curative intent.

Irinotecan plus folinic acid/continuous 5-fluorouracil as simplified bimonthly FOLFIRI regimen for first-line therapy of metastatic colorectal cancer.

BACKGROUND: Combination therapy of irinotecan, folinic acid (FA) and 5-fluorouracil (5-FU) has been proven to be highly effective for the treatment of metastatic colorectal cancer. However, in light of safety and efficacy concerns, the best combination regimen for first-line therapy still needs to be defined. The current study reports on the bimonthly FOLFIRI protocol consisting of irinotecan with continuous FA/5-FU in five German outpatient clinics, with emphasis on the safety and efficiency, quality of life, management of delayed diarrhea, and secondary resection of regressive liver metastases. METHODS: A total of 35 patients were treated for metastatic colorectal cancer. All patients received first-line treatment according to the FOLFIRI regimen, consisting of irinotecan (180 mg/m2), L-FA (200 mg/m2) and 5-FU bolus (400 mg/m2) on day 1, followed by a 46-h continuous infusion 5-FU (2400 mg/m2). One cycle contained three fortnightly administrations. Staging was performed after 2 cycles. Dosage was reduced at any time if toxicity NCI CTC grade III/IV was observed. Chemotherapy was administered only to diarrhea-free patients. RESULTS: The FOLFIRI regimen was generally well tolerated. It was postponed for one-week in 51 of 415 applications (12.3%). Dose reduction was necessary in ten patients. Grade III/IV toxicity was rare, with diarrhea (14%), nausea/vomiting (12%), leucopenia (3%), neutropenia (9%) and mucositis (3%). The overall response rate was 31% (4 CR and 7 PR), with disease control in 74%. After primary chemotherapy, resection of liver metastases was achieved in three patients. In one patient, the CR was confirmed pathologically. Median progression-free and overall survival were seven and 17 months, respectively. CONCLUSIONS: The FOLFIRI regimen proved to be safe and efficient. Outpatient treatment was well tolerated. Since downstaging was possible, combinations of irinotecan and continuous FA/5-FU should further be investigated in neoadjuvant protocols.
