    The place of downstaging for hepatocellular carcinoma

    Get PDF
    In the treatment of hepatocellular carcinomas, therapies such as trans-arterial chemo-embolisation, trans-arterial radioembolisation, percutaneous ethanol injection and radio-frequency ablation can decrease the size (and overall viability) of the tumours, thus potentially increasing the proportion of patients qualifying for resection and transplantation.While the use of such downstaging therapies is straightforward when resection is the aim, in a similar way to other neo-adjuvant treatments in the surgery of tumours that are too large or awkwardly placed to be primarily resected the issues related to transplantation are more complex. In the context of transplantation the word “downstaging” designates not only a neo-adjuvant treatment, but also a selection strategy to allow patients who are initially outside accepted listing criteria to benefit from transplantation should the neo-adjuvant therapy be successful in reducing tumour burden. The effectiveness of downstaging as a selection strategy, at first questioned because of methodological bias in the studies that described it, has been recently demonstrated by more solid prospective investigations. Several issues however remain open, such as inclusion criteria before the strategy is implemented (size/number, surrogate markers of differentiation/vascular invasion such as alpha-fetoprotein), the choice of which downstaging therapy, the end-points of treatment, and the need and duration of a period of observation proving disease response or stabilisation before the patient can be listed.The present review discusses which treatments and strategies are available for downstaging HCC on the basis of the published literature

    Background:: A phase I-II multicenter trial was conducted to define the maximal tolerated dose and describe the activity of an OCFL combination using oxaliplatin (OHP), irinotecan (CPT-11) and 5-fluorouracil (FU)/leucovorin (LV) in metastatic colorectal cancer (CRC). Patients and methods:: CRC patients not pretreated with palliative chemotherapy, with performance status ≀1 and adequate haematological, kidney and liver function, were eligible. Treatment consisted in weekly 24-h infusion 5-FU (2300 mg/m2)/LV (30 mg) and alternating OHP (70-85 mg/m2, days 1 and 15) and CPT-11 (80-140 mg/m2, days 8 and 22) repeated every 5 weeks. OHP and CPT-11 were escalated in cohorts of three to six patients. Results:: Thirty patients received a median of five cycles. Dose-limiting toxicity occurred at dose level 3, and the recommended dose was OHP 70 mg/m2, CPT-11 100 mg/m2, LV 30 mg and 5-FU 2300 mg/m2/24 h. Grade ≄3 toxicities were diarrhea 23%, neutropenia 20%, fatigue 7%, and neurologic 7%. Two febrile neutropenia episodes (one fatal) were recorded. Among 28 patients with measurable disease (90%), we observed two complete and 20 partial responses; overall RR was 78% (95% CI, 59% to 92%). Median time to progression and overall survival were 9.5 and 25.4 months, respectively. Seven patients underwent liver metastases resection. Conclusion:: OCFL is an overall well tolerated regimen with very high efficacy, which makes it most suitable for tumour control before surgery of metastatic diseas

    Background: In advanced metastatic colorectal adenocarcinoma, the addition of a neo-adjuvant systemic treatment to surgery might translate into a survival advantage, although this is yet to be confirmed by ongoing randomized trials. The objective of this study was to assess the effects of preoperative systemic chemotherapy on the morphology of non-tumoral liver. Patients and methods: A large series of surgically resected liver metastases (n = 153) was selected. Light microscopy, electron microscopy, and immunohistochemistry using antibodies against endothelial cells (CD31) and hepatic stellate cells (α-SM actin, CRBP-1) were performed to identify sinusoidal wall integrity. Results: We found that 44 (51%) of the 87 post-chemotherapic liver resection specimens had sinusoidal dilatation and hemorrhage, related to rupture of the sinusoidal barrier. In contrast, the 66 livers treated by surgery alone remained normal. In 21 out of the 44 post-chemotherapy patients (48%), perisinusoidal and veno-occlusive fibrosis also developed. Sinusoidal injury persisted several months after end of chemotherapy, and fibrosis may progress. Development of lesions was strongly correlated to the use of oxaliplatin; 34 out of 43 patients (78%) treated with this drug showed striking sinusoidal alterations. Conclusions: Systemic neo-adjuvant chemotherapy in metastatic colorectal cancer frequently causes morphological lesions involving hepatic microvasculature. Sinusoidal obstruction, complicated by perisinusoidal fibrosis and veno-occlusive lesion of the non-tumoral liver revealed by this study, should be included in the list of the adverse side-effects of colorectal systemic chemotherapy, in particular related to the use of oxaliplati

    Is the Clinical Risk Score for Patients with Colorectal Liver Metastases Still Useable in the Era of Effective Neoadjuvant Chemotherapy?

    Background: Several clinical risk scores (CRSs) for the outcome of patients with colorectal liver metastases have been validated, but not in patients undergoing neoadjuvant chemotherapy. Therefore, this study evaluates the predictive value of these CRSs in this specific group. Methods: Between January 2000 and December 2008, all patients undergoing a metastasectomy were analyzed and divided into two groups: 193 patients did not receive neoadjuvant chemotherapy (group A), and 159 patients received neoadjuvant chemotherapy (group B). In group B, the CRSs were calculated before and after administration of neoadjuvant chemotherapy. Results were evaluated by using the CRSs proposed by Nordlinger et al., Fong et al., Nagashima et al., and Konopke et al. Results: In groups A and B, the overall median survival was 43 and 47 months, respectively (P = 0.648). In group A, all CRSs used were of statistically significant predictive value. Before administration of neoadjuvant chemotherapy, only the Nordlinger score was of predictive value. After administration of neoadjuvant chemotherapy, all CRSs were of predictive value again, except for the Konopke score. Conclusions: Traditional CRSs are not a reliable prognostic tool when used in patients before treatment with neoadjuvant chemotherapy. However, CRSs assessed after the administration of neoadjuvant chemotherapy are useful to predict prognosis

    Primary treatment of rectal cancer was the focus of the second St. Gallen European Organisation for Research and Treatment of Cancer (EORTC) Gastrointestinal Cancer Conference. In the context of the conference, a multidisciplinary international expert panel discussed and voted on controversial issues which could not be easily answered using published evidence. Main topics included optimal pretherapeutic imaging, indication and type of neoadjuvant treatment, and the treatment strategies in advanced tumours. Here we report the key recommendations and summarise the related evidence. The treatment strategy for localised rectal cancer varies from local excision in early tumours to neoadjuvant radiochemotherapy (RCT) in combination with extended surgery in locally advanced disease. Optimal pretherapeutic staging is a key to any treatment decision. The panel recommended magnetic resonance imaging (MRI) or MRI + endoscopic ultrasonography (EUS) as mandatory staging modalities, except for early T1 cancers with an option for local excision, where EUS in addition to MRI was considered to be most important because of its superior near-field resolution. Primary surgery with total mesorectal excision was recommended by most panellists for some early tumours with limited risk of recurrence (i.e. cT1-2 or cT3a N0 with clear mesorectal fascia on MRI and clearly above the levator muscles), whereas all other stages were considered for multimodal treatment. The consensus panel recommended long-course RCT over short-course radiotherapy for most clinical situations where neoadjuvant treatment is indicated, with the exception of T3a/b N0 tumours where short-course radiotherapy or even no neoadjuvant therapy were regarded to be an option. In patients with potentially resectable tumours and synchronous liver metastases, most panel members did not see an indication to start with classical fluoropyrimidine-based RCT but rather favoured preoperative short-course radiotherapy with systemic combination chemotherapy or alternatively a liver-first resection approach in resectable metastases, which both allow optimal systemic therapy for the metastatic disease. In general, proper patient selection and discussion in an experienced multidisciplinary team was considered as crucial component of care

    Die Bedeutung der Neurobiologie fĂŒr die Kinder- und Jugendlichentherapie

    Welche Bedeutung haben die in den letzten beiden Jahrzehnten erarbeiteten neurobiologischen Forschungsergebnisse fĂŒr die Praxis der Kinder- und Jugendlichentherapie? Das ist die Frage, mit der ich mich im Folgenden beschĂ€ft igen möchte. Ich selber schwanke immer zwischen zwei Extremen: Einerseits fi nde ich es faszinierend, ĂŒber neuere neurobiologische Erkenntnisse zu lesen und ihre Bedeutung fĂŒr die Psychotherapie mit Kindern und Jugendlichen zu refl ektieren. Andererseits habe ich oft den Eindruck, dass die zweifellos beeindruckenden Forschungsmethoden doch nur sehr eingeschrĂ€nkt in der Lage sind, etwas von der KomplexitĂ€t der VorgĂ€nge im Gehirn zu erfassen. Sie fordern die Forscher damit zu Interpretationen heraus mit der Folge, dass manche von ihnen darin genau das entdecken, wovon sie vorher ĂŒberzeugt waren. Sicherlich kommen umfangreiche neurobiologische Forschungen in vielen FĂ€llen auch zu Ergebnissen, die aufgrund des inzwischen doch sehr großen psychotherapeutischen Erfahrungsschatzes ziemlich selbstverstĂ€ndlich, sozusagen als alte HĂŒte wirken. Das mindert mein persönliches Interesse allerdings nicht. Denn nach meiner Erfahrung ist es oft sehr bereichernd, auch alte HĂŒte mal von einer anderen Seite und unter anderen Aspekten zu betrachten. Und ich erlebe es als sehr spannend zu beobachten, welche Teile dieses therapeutischen Erfahrungsschatzes sich nicht bestĂ€tigen werden

    Living donor liver transplantation with extensive caval thrombectomy for acute-on-chronic Budd-Chiari syndrome.

    Get PDF
    The key consideration when performing living donor liver transplantation (LDLT) in patients with Budd-Chiari syndrome (BCS) is careful management of a stenotic or occluded inferior vena cava (IVC), because it is not possible to replace the recipient stenotic or occluded IVC with donor IVC as in cadaver donor transplantation. We describe how we performed LDLT with extensive thrombectomy in a patient with acute-on-chronic BCS with a totally thrombosed retrohepatic IVC. The operation was successful and the patient remains well, with follow-up images showing a patent IVC and hepatic veins. To our knowledge, LDLT for a BCS patient with severe extensive caval thrombus has never been reported before. We consider that the successful outcome of this patient clearly demonstrates the feasibility of our technique of extensive thrombectomy, without a vessel graft, to manage a stenotic or occluded IVC in LDLT in patients with BCS
