Abstract
PURPOSE Bilobar colorectal liver metastases (CRLM) are often considered incurable or associated with poor prognosis even after R0 resection. In this single-center study, we evaluate the impact of CRLM spreading on recurrence-free survival (RFS) and cancer-specific overall survival (CSS) after R0 resection of CRLM with respect to multimodal treatment strategies including perioperative chemotherapy and multistep resections. METHODS Between January 2001 and December 2010, R0 resection could be achieved in 70 patients with bilobar and 100 with unilobar CRLM. Extent of disease, perioperative chemotherapy, surgical procedures, adjuvant treatment, histopathological workup, RFS, and CSS were compared between both cohorts. RESULTS Forty-six (66 %) patients with bilobar and 26 (26 %) patients with unilobar CRLM received preoperative chemotherapy (p < 0.001). For bilobar CRLM, more extended and multistep resection including portal vein occlusion were performed (29 % versus 3 %; p < 0.001). Morbidity (39 % versus 28 %, p = 0.183) and mortality (1 % versus 3 %, p = 0.644) rates were comparable in both patients' cohorts. Postoperative therapy was applied in adjuvant intent to 42 (60 %) versus 51 (51 %) patients (p = 0.275). The 5-year RFS and CSS rates were 24 % versus 31 % (p = 0.169) and 42 % versus 55 % (p = 0.131), respectively. CONCLUSIONS To our single-center experience, there is no significant effect of CRLM spreading (bilobar versus unilobar) on RFS and CSS rates. Bilobar CRLM are more likely to require extended multimodal efforts to achieve R0 resection.

Abstract
OBJECTIVE Numerous studies have found a robust association between cannabis use and the onset of psychosis. Nevertheless, the relationship between cannabis use and the onset of early (or, in retrospect, prodromal) symptoms of psychosis remains unclear. The study focused on investigating the relationship between cannabis use and early and high-risk symptoms in subjects at clinical high risk for psychosis. METHOD Prospective multicenter, naturalistic field study with an 18-month follow-up period in 245 help-seeking individuals clinically at high risk. The Composite International Diagnostic Interview was used to assess their cannabis use. Age at onset of high risk or certain early symptoms was assessed retrospectively with the Interview for the Retrospective Assessment of the Onset of Schizophrenia. RESULTS Younger age at onset of cannabis use or a cannabis use disorder was significantly related to younger age at onset of six symptoms (0.33 < r(s) < 0.83, 0.004 < P < 0.001). Onset of cannabis use preceded symptoms in most participants. CONCLUSION Our results provide support that cannabis use plays an important role in the development of psychosis in vulnerable individuals. Cannabis use in early adolescence should be discouraged.

Abstract
OBJECTIVES The various biologic agents currently available for the treatment of RA can be administered subcutaneously (s.c.) or via intravenous (i.v.) infusion with variable intervals depending on the drug. This investigation aims to identify the preferences and concerns of affected patients and their physicians. METHODS We conducted a survey of 102 patients with RA currently receiving Rituximab (RTX) therapy. They were asked about different aspects of their current and previous RA therapy, including overall satisfaction, tolerability, mode of drug administration, as well as duration and intervals. In addition, 17 rheumatologists were asked about different aspects of s.c. or i.v. drug administration, their preference and the suspected preference of their patients. RESULTS The mean age of our patients was 59 ± 11.2 years. Patients had failed ≥2 DMARD therapies and ≥ 1 biologic treatment. The impact of RTX infusions on planning different activities including job, hobbies or travelling was considered as low or very low in 76% of the respondents. Interestingly, 63.4% of patients would prefer an infusion every 6-9 months as RA therapy, whereas 21.5% would prefer tablets only; 12.9% of our patient cohort would prefer s.c. injections every second week, and only 2% would prefer an infusion every month. In all, 92% of patients questioned would choose RTX therapy again. In contrast, 88% of rheumatologists preferred s.c. injection and even 94% of them assumed that their patients would do so as well if they had the choice. The suggested reasons included greater flexibility, convenience and independence during s.c. therapy. CONCLUSION Contrary to the assumption of rheumatologists, we have demonstrated a preference among RTX patients for i.v. drug administration every 6-9 months over other methods of administration.

Abstract
Preoperative 5-fluorouracil-based radiochemotherapy (RCT) followed by quality assessed total mesorectal excision (TME surgery) are the two most important elements of multimodal treatment for patients with locally advanced rectal cancer (UICC stages II and III). The optimum sequence of these neoadjuvant modalities complemented by adjuvant (postoperative) chemotherapy, has been addressed in several randomised trials. Especially within the trials of the German Rectal Cancer Study Group (GRCSG), preoperative RCT has been shown to be superior to postoperative treatment for a variety of endpoints (pathologically confirmed complete tumour remission (pCR), RCT-induced tumour regression, R0 resection rates (including circumferential resection margins) and long-term locoregional control). This neoadjuvant multimodal strategy has decreased the 5-year and 10-year local recurrence rates below 10%, and the development of distant metastases (e.g., 35% to 45% liver metastases) remains the predominant reason for failure. Furthermore, approximately 25% of patients do not receive adjuvant chemotherapy, mainly due to surgical complications, patients' refusal or the investigator's discretion. Thus, today, integrating more effective systemic therapy into (preoperative) multimodal regimens is the most accepted challenge! But from the clinical point of view this demand is also a dilemma. The question to be addressed is how and when to apply intensified systemic therapy with adequate dosage and intensity as well as acceptable treatment-associated toxicity. The increase of therapeutic options requires valid predictive biomarkers that may help to stratify patients into regimens associated with low toxicity (5-FU monotherapy alone) or into more intensified treatment for better long-term outcome. In summary, the use of biomarkers for individualised risk-adapted treatment is one of the most promising areas of clinical investigations, not only in rectal cancer. The assessment of individual tumour response, toxicity, and prognosis during multimodal treatment of rectal cancer as a model of a very common solid tumour offers radiooncologists, surgeons, pathologists, gastroenterologists as well as oncologists immense insights into the under-standing of tumour biology.

Abstract
LBA3505 Background: The German CAO/ARO/AIO-94 trial established preoperative chemoradiotherapy (CRT), surgery, and postoperative chemotherapy with 5-FU as standard treatment for locally advanced rectal cancer. With this approach local relapse rates are below 10%. The development of distant metastasis is the predominant mode of failure. Integrating more effective systemic treatment into combined modality therapy was the goal of CAO/ARO/AIO-04. Methods: Between 7/2006-2/2010, patients with rectal cancer within 12 cm from the anal verge and clinical evidence of perirectal fat or lymph node involvement were randomly assigned to receive preoperative CRT, surgery, and adjuvant chemotherapy with 5-FU according to CAO/ARO/AIO-94 (arm 1), or preoperative CRT (50.4 Gy in 28 fractions) with 5-FU (250 mg/m2/days 1-14 and 22-35) and oxaliplatin (50 mg/m2/days 1, 8, 22, 29), surgery, and 8 cycles of adjuvant chemotherapy according to modified FOLFOX6 regimen (arm 2). Disease-free survival was the primary endpoint. We present early secondary endpoints, including acute toxicity, treatment compliance, and pCR-rates. Results: 637 patients were randomly assigned to arm 1 and 628 to arm 2. Full dose preoperative RT and full dose concurrent chemotherapy was delivered in 97% and 74% of patients in both arms, respectively. Preoperative grade 3/4 toxicity occurred in 21.6% in arm 1 and in 22.9% in arm 2. The R0-resection rate was 95.4% in both arms, and abdominoperineal resections were limited to 11.9% and 12.2% in arms 1 and 2, respectively. Overall postoperative complications were not different between both arms (21.0% and 21.9%). The pCR rate (ypT0N0) was 13.1% in arm 1 and 17.6% in arm 2 (p = 0.033, Cochran-Mantel-Haenszel Chi-Squared Test without continuity correction for conditional independence of pCR rate in the two treatment arms in each stratum). Conclusions: Inclusion of oxaliplatin to 5-FU based CRT was well tolerated and associated with increased pCR-rates compared with 5-FU-CRT alone. Longer follow-up is necessary to evaluate the primary endpoint, disease-free survival.

Abstract
AbstractIn the last few years, industrial research into materials fulfilling the needs of the maturing OLED display industry has intensified considerably. A first generation of polymers (phenyl- PPVs) is now being commercially exploited in first monochrome polymer LED display applications. Based on these materials, non-planar displays have already been demonstrated. However, those proof of concept devices have been monochrome. Especially the RGB materials need considerable improvement to be suitable for flexible full color displays.We will therefore report on the progress in the development of polymers for red, green, and blue emission. Our main focus here is on improving the properties of various polymers derived from the spiro-bifluorene core.Depending on the color, the main issues vary strongly: For BLUE polymers, efficiency, color coordinates, and processibility are already at a commercial level while operational lifetime still needs strong improvement. RED materials are in an almost contrary situation: here, the operational lifetime is excellent, whereas the efficiency and the driving current are requiring further improvement. For GREEN, achieving saturated emission, whilst maintaining the other properties (high efficiency, long operational lifetime), is still challenging. We will demonstrate the current status of material development within Covion.In addition, we achieved advances in full-color patterning, especially techniques based on Ink-Jet printing. This technology potentially allows the efficient manufacturing of high resolution RGB devices on a variety of substrates, including flexible layers.

Abstract
483 Background: Valid molecular markers need to be implemented in clinical trials to fulfill the demand of a risk-adapted and more individualized multimodal therapy of locally advanced primary rectal cancer. In the present study the expression of the inhibitor-of-apoptosis (IAP) protein Survivin was evaluated in pre-treatment biopsies and corresponding post-treatment resection specimens, and was correlated to histo-pathological tumor characteristics and clinical follow-up. Methods: 116 patients with stage II/III rectal cancer treated with 5-FU-based neoadjuvant radiochemotherapy (RCT) within the German Rectal Cancer Trials were investigated. Survivin expression in pre-treatment biopsies and surgical resection specimens were determined by immunohistochemistry by two independent institutions and correlated with histopathologic parameters, tumor recurrences, disease-free and overall cancer-specific survival. Results: In pre-treatment biopsies, a higher Survivin expression correlated with advanced ypT (p=0.026) and ypUICC (p=0.05) stage as well as decreased disease-free survival (p=0.038) after preoperative RCT. High post-treatment Survivin levels were associated with advanced ypT stage (p=0.03) and residual lymph node metastases (p=0.04). Moreover, neoadjuvant RCT resulted in a significant down-regulation of Survivin expression (p < 0.0001). A failure of RCT-induced down-regulation was associated with development of distant metastases (p=0.0056) and cancer-related death (p=0.026), and was significantly correlated with disease-free (p=0.011*/0.02**) and cancer-specific survival (p=0.0017*/0.01**) in uni*- and multivariate** analyses. Conclusions: Survivin expression displays a marker with prognostic validity in rectal cancers. These results underline the usefulness of Survivin to monitor individual response to RCT in rectal cancer, and encourage anti-Survivin strategies in multimodal rectal cancer therapy within future randomised clinical trials.

Abstract
435 Background: Fluorouracil (5FU) remains the backbone of neoadjuvant radiochemotherapy (RCT) as well as adjuvant therapeutic strategies in multimodal treatment of rectal cancer patients. Due to its central role as the major target of 5FU thymidylate synthase (TS) is a promising biomarker in rectal cancer. We assessed TS in 208 patients with regard to its predictive/prognostic capacity for disease free DFS and overall cancer specific survival (CSS). Methods: 167 patients cUICC stages II (28%) and III (72%) received preoperative 5FU based RCT followed by total mesorectal excision (TME) A comparison group n = 41 received postoperative RCT after primary TME. All patients were treated after standardized protocols within phase-II/-III trials of the German Rectal Cancer Study Group. TS levels from pretreatment biopsies and corresponding resection specimens were assessed by immunohistochemical staining for their impact on DFS and CSS. Additionally, a TS gene polymorphism (28 bp repeat) was analysed in respect to intracellular protein expression levels and prognostic significance. Results: Patients with low TS expression in pre-treatment biopsies showed a correlation with impaired CSS (p = 0.015). After neoadjuvant RCT there was evidence of lymph node metastases ypUICC stage III in 32.6%. Complete histopathologically confirmed tumor regression TRG 4 was achieved in 16 patients (9.5%). During follow-up (median 57 months) patients with low intratumoral TS expression and positive nodal status were at high risk for local and/or distant metastatic recurrence (p = 0.040). Analysis of the 28bp repeat revealed a correlation of *3/*3 genotype with high TS expression in pretherapeutical biopsies (p = 0.05). Conclusions: TS represents a prognostic biomarker in locally advanced rectal cancer indicating an unfavourable outcome for patients with low TS expression and might help to adapt adjuvant therapy regimens by stratifying patients according to their risk for cancer recurrence. No significant financial relationships to disclose.

Abstract
Objective: The objective of our study was to field test different chronic migraine (CM) criteria and compare CM epidemiological profiles, which include demographic, personal, and lifestyle characteristics, with high-frequency episodic migraine (HFEM) and low-frequency episodic migraine (LFEM). Methods: Questionnaires were mailed to a random sample of 18,000 18–65-year-olds in demographically diverse regions of Germany. The epidemiological data for the three classifications of CM, LFEM and HFEM were assessed using descriptive statistics, Pearson Chi-square, and analysis of variance tests. Results: Among 9350 respondents, CM_I was the most restrictive ( N = 37, 0.4%), followed by CM_II ( N = 45, 0.5%) and CM_III ( N = 185, 2.0%). CM groups did not differ in distribution by age, gender, body mass index, education or smoking and alcohol consumption. Compared to those with LFEM and HFEM, those with CM (CM_III) had significantly different epidemiological profiles. Conclusions: CM prevalence varies by case definition. The epidemiological profiles of the three CM groups are similar but differ significantly from those of HFEM and LFEM. Optimal definitions for clinical practice and epidemiological research require additional field testing.

Abstract
This report concerns a 41-year-old female patient with a huge meningioma which was preoperatively embolized with polyvinyl alcohol particles (PVA, 100-300 μm) via the left middle meningeal artery. Dangerous vascular anastomoses were not previously recognized in a superselective angiography. Aphasia and hemiparesis on the right side occurred immediately after the embolization. A cerebral infarct was seen in the region of the left pericallosal artery. The patient applied to the fact-finding board for medical liability and a neuroradiologic opinion was requested. The board came to the conclusion that no incorrect medical treatment had been carried out.

Abstract
Report of a 33-year-old woman who had sudden vision problems and homonymous hemianopia on the left. A cranial computed tomography (CCT) was carried out in a radiologic practice. A native homogeneous, smooth-edged hyperdense intracerebral mass of about 5.5 cm diameter on the right parietooccipital region with density values of +50 HU was found. Only a small proportion of about 2 cm diameter was more hyperdense with density values of +65 HU. Following intravenous administration of contrast medium, a patchy increase in density of about 1 cm was seen. The mass had only a thin hypodense rim. The patient was informed that she had a tumor. Three days later, magnetic resonance imaging was to be done for further evaluation. After the patient had returned home, she had headaches, nausea and vomiting in the evening. At night, she was admitted to a hospital as emergency case. With further increase of intracranial pressure, a craniotomy was done and a hemorrhage was removed. Histologically, a bleeding of a cavernous hemangioma was found. The patient appealed to the fact-finding board for medical liability questions because she had not been admitted to a hospital immediately after the CCT. Therefore, surgery was done delayed. The board found that the behavior of the radiologist was wrong. However, it cannot be proven that this medical malpractice is of importance for the existing postoperative complaints.

Abstract
Based on results of the German Rectal Cancer Study Group CAO/ARO/AIO-94 trial, long-term chemoradiotherapy (RT/CTx) is recommended as standard treatment for locally advanced rectal cancer (UICC stages II/III) in the lower two thirds of the rectum (0-12 cm from the anocutaneous verge). Tumor response to neoadjuvant therapy is very heterogeneous, ranging from complete remission to total resistance to RT/CTx. To fulfill the clinical requirement of individual and risk-adapted multimodal treatment, distinct progress in translational research has been achieved (e.g. gene profiling). However, in clinical reality "individualization" of the therapy of rectal cancer patients has not actually been realized. This can be achieved only on the basis of successful randomized clinical trials (e.g. the CAO/ARO/AIO-04 and GAST-05 trials) translationally combined with basic scientific approaches. One simple first step toward individualizing rectal cancer therapy is being made with the ongoing GAST-05 trial. This investigator initiated phase II trial funded by the German Research Foundation (Deutsche Forschungsgemeinschaft) excludes preoperative RT/CTx for patients with rectal cancer localized in the upper third of the rectum, using only quality controlled principles of radical surgery (partial vs total mesorectal excision) followed by adjuvant chemotherapy.

Abstract
Introduction Blood loss during radical prostatectomy has been a long term issue. The aim of this study was to investigate the influence of the training level of the first assistant regarding blood loss in open retropubic radical prostatectomy at an educational hospital. Material and methods 364 patients underwent radical prostatectomy from 11/2006 to 10/2007 at one institution operated by one surgeon. In 319 patients all predefined parameters were obtained. Training level was determined by year of residency (1-5 yrs) or consultant status. Perioperative blood loss was calculated using three parameters: Hemoglobin level before and after surgery, postoperative sucker volume and weight of compresses. Furthermore the influence of prostatic size and BMI was analyzed. Results The Hb-decrease 24 h postoperatively was 2.4 g/dl median (-0.4-7.6 g/dl); sucker volume was 250 ml median (10-1500 ml); weight of compresses and swabs was 412 g median (0-972 g). One patient needed a transfusion with two erythrocyte concentrates one day after the surgery. There was no significant correlation regarding Hb-decrease (p = 0.86) or sucker volume plus weight of compresses (p = 0.59) in regard to the years of residency of the assisting physician. Also the number of assisted operations (n = < or > 20) had no significant influence on calculated blood loss (p = 0.38). Conclusions For an experienced surgeon the impact of the assistant regarding blood loss seems negligible. The training level of the assistant was not significantly correlated to a rise or decrease of perioperative blood loss. In our data radical prostatectomy could be safely performed at an educational hospital independent of the training level of the first assistant.

Abstract
7000 Background: In younger CN AML without FLT3-ITD, NPM1 mutations predict favorable outcome. Their prognostic impact in older [≥60 years (y)] patients (pts) requires further evaluation. Methods: Pretreatment marrow was studied in 189 older CN AML pts [median age 69 y (60 - 83 y); 162 de novo & 27 secondary (s; prior hematologic disorders) cases] enrolled on CALGB 9720 (n=106) & 10201 (n=83). Both protocols had standard-dose (100 mg/m2/d) cytarabine (AraC)/daunorubicin (DN)-based induction; consolidation was based on standard-dose AraC/DN/etoposide (1 cycle) in 9720 & intermediate-dose (2 g/m2/d) AraC (2 cycles) in 10201. Pts transplanted in 1st complete remission (CR) were excluded. Median follow-up was 3.3 y for pts alive. Analyses of NPM1 exon 12 by direct sequencing, gene & microRNA (miR) expression profiling by Affymetrix U133 plus 2.0 & OSU CCC v4.0 arrays, & other markers (FLT3-ITD, FLT3-TKD, WT1mut) were performed centrally. Results: In de novo CN AML, NPM1 mutated (NPM1mut) pts (54%) had more CRs (85% v 45%, P<.0001) & longer relapse-free (RFS) (P=.02; 3 y rates 23% v 10%) & overall survival (OS) (P<.0001; 3 y 34% v 7%) than NPM1 wild-type (NPM1wt) pts. In multivariable models, NPM1 mutations independently predicted favorable outcome (Table) - NPM1mut pts had 10-fold higher odds of CR & 64% reduction in relapse risk. In genome-wide analyses, miR-10 & miR-16 were upregulated in NPM1mut pts, accompanied by highly expressed HOX genes & downregulated BCL2, respectively. NPM1mut were rare in sAML pts (15%), precluding study of their impact. Conclusions: NPM1 mutations independently predict better outcome in older CN AML. Upregulation of proapoptotic microRNAs & downregulation of antiapoptotic microRNA targets may explain the impact of NPM1 mutations.

The mesopancreas is the primary site for R1 resection in pancreatic head cancer: relevance for clinical trials. Langenbecks Arch Surg 2009; 395:451-8.

Abstract
Purpose The prognosis of patients with pancreatic cancer remains poor, even after potentially curative R0 resection. This discrepancy may be due to the histopathological misclassification of R1 cases as curative resections (R0) in the past. Materials and methods To test this hypothesis, color coding of all resection margins and organ surfaces as part of a standardized histopathological workup was implemented and prospectively tested on 100 pancreatic head specimens. Results Thirty-five patients were excluded from the analysis owing to the pathohistological diagnosis; only pancreatic ductal adenocarcinoma, distal bile duct adenocarcinoma, and periampullary adenocarcinoma were included. Applying the International Union Against Cancer criteria, 32 cancer resections were classified R0 (49.2%), while 33 cases turned out to be R1 resections (50.8%). The mesopancreas was infiltrated in 22 of the 33 R1 resection specimens (66.6%). It proved to be the only site of tumor infiltration in 17 specimens (51.5%). Applying the Royal College of Pathologists’ criteria, 46 resections were classified R1 (70.8%). As expected, the mesopancreas again was the most frequent site of noncurative resection (n = 27; 58.7%). Conclusion Using the intensified histopathological workup for pancreatic head cancer specimens resulted in an increased rate of R1 resections and the mesopancreas represents the primary site for positive resection margins. Such results are of relevance for patients’ stratification in clinical trials.

Abstract
The aim of this multicentre study was to compare T1 with T2 weighted MRI scans of the labyrinth after meningitis and to investigate whether waiting with scanning improved the reliability of diagnosing an ongoing process such as cochlear osteogenesis. Forty-five patients were included who suffered from meningitis induced hearing loss (radiological imaging <1 year after meningitis). Twenty-one gadolinium enhanced T1 and 45 T2 weighted MRI scans were scored by two radiologists regarding the condition of the labyrinth. These radiological observations were compared with the condition of the cochlea as described during cochlear implantation. A higher percentage of agreement with surgery was found for T2 (both radiologists 73%) than for T1 weighted MRI scans (radiologist 1: 62%, radiologist 2: 67%), but this difference is not significant. There was no significant difference between early (0–3 months) and late (>3 months) scanning, showing that radiological imaging soon after meningitis allows early diagnosis without suffering from a lower agreement with surgical findings.

Abstract
Marfan syndrome is an autosomal dominant disorder involving different organ systems. Marfan syndrome type 1 (MFS1) is caused by mutations in the FBN1 gene. Heterozygosity for mutations in the TGFBR1 or TGFBR2 genes cause Loeys-Dietz syndrome (LDS) types 2A and 2B that overlap with MFS1 in their clinical features. The phenotype of MFS1 is defined by the Ghent nosology, which classifies the clinical manifestations in major and minor criteria. Dural ectasia is one of the major criteria for Marfan syndrome but it is rarely tested for. We here report 22 novel and 9 recurrent mutations in the FBN1 gene in 36 patients with clinical features of Marfan syndrome. Sixty patients with identified mutations in the FBN1 gene and three patients with mutations in the TGFBR1 or TGFBR2 genes were examined for dural ectasia. Forty-seven of the 60 patients (78%) with MFS1 showed the dural ectasia criterion and 13 (22%) did not. Thirty-three (55%) patients were suspected of having Marfan syndrome and 24 (73%) of them had dural ectasia. Two of the three patients with LDS had dural ectasia.

Abstract
BACKGROUND AND AIMS Patients with bilobular colorectal liver metastases (CRLM) experience poor prognosis, especially when curative resection cannot be achieved. However, resectability in these patients is often limited by low future remnant liver volume (FRLV). The latter can be enhanced by a two-stage liver resection, using portal vein ligation to induce liver hypertrophy. The aim of this prospective pilot study was to evaluate safety, secondary resectability, and time to recurrence of two-stage hepatectomy with portal vein ligation (PVL) and complete surgical clearance of the FRLV in patients with bilobular CRLM. MATERIALS AND METHODS Out of 24 patients (63+/-8.26 years) with extended bilobular CRLM (metachronous n=10, synchronous n=14), 18 received preoperative 5-FU-based chemotherapy combined with oxaliplatin or irinotecan. Staging included thoracoabdominal computed tomography and (18)F-fluorodeoxyglucose-positron emission tomography scans. First-stage procedure consisted of PVL, resection of all CRLM in the FRLV, and radiofrequency ablation (RFA) of CRLM situated near the future resection plane. RESULTS During first-stage procedure, 7x RFA, 4x non-anatomical resections, and 4x bisegmentectomies were performed additionally to PVL. FRLV/body-weight ratio increased from 0.4% to 0.6% within 55 days (median) after PVL. Second-stage hepatectomy was performed in 19 patients without tumor progression. R0 resection was possible in 14 patients. During a median follow-up of 17 months, intrahepatic recurrence occurred in two, and extrahepatic recurrence in nine out of 14 patients. CONCLUSION Two-stage hepatectomy with PVL and complete surgical clearance of FRLV is safe even after intensified systemic chemotherapy resulting in a curative resection rate of 58.3% (73.7% of re-explored cases).
