RESUMO

Background: In respect of the principle of autonomy and the right of self-determination, obtaining an informed consent of potential participants before their inclusion in a study is a fundamental ethical obligation. The variations in national laws, regulations, and cultures contribute to complex informed consent documents for patients participating in clinical trials. Currently, only few ethics committees seem willing to address the complexity and the length of these documents and to request investigators and sponsors to revise them in a way to make them understandable for potential participants. The purpose of this work is to focus on the written information in the informed consent documentation for drug development clinical trials and suggests (i) to distinguish between necessary and not essential information, (ii) to define the optimal format allowing the best legibility of those documents. Methods: The Aide et Recherche en Cancérologie Digestive (ARCAD) Group, an international scientific committee involving oncologists from all over the world, addressed these issues and developed and uniformly accepted a simplified informed consent documentation for future clinical research. Results: A simplified form of informed consent with the leading part of 1200-1800 words containing all of the key information necessary to meet ethical and regulatory requirements and 'relevant supportive information appendix' of 2000-3000 words is provided. Conclusions: This position paper, on the basis of the ARCAD Group experts discussions, proposes our informed consent model and the rationale for its content.

RESUMO

BACKGROUND: The phase III RAINBOW trial demonstrated that the addition of ramucirumab to paclitaxel improved overall survival, progression-free survival, and tumor response rate in fluoropyrimidine-platinum previously treated patients with advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. Here, we present results from quality-of-life (QoL) and performance status (PS) analyses. PATIENTS AND METHODS: Patients with Eastern Cooperative Oncology Group PS of 0/1 were randomized to receive ramucirumab (8 mg/kg i.v.) or placebo on days 1 and 15 of a 4-week cycle, with both arms receiving paclitaxel (80 mg/m(2)) on days 1, 8, and 15. Patient-reported outcomes were assessed with the QoL/health status questionnaires EORTC QLQ-C30 and EQ-5D at baseline and 6-week intervals. PS was assessed at baseline and day 1 of every cycle. Time to deterioration (TtD) in each QLQ-C30 scale was defined as randomization to first worsening of ≥10 points (on 100-point scale) and TtD in PS was defined as first worsening to ≥2. Hazard ratios (HRs) for treatment effect were estimated using stratified Cox proportional hazards models. RESULTS: Of the 665 patients randomized, 650 (98%) provided baseline QLQ-C30 and EQ-5D data, and 560 (84%) also provided data from ≥1 postbaseline time point. Baseline scores for both instruments were similar between arms. Of the 15 QLQ-C30 scales, 14 had HR < 1, indicating similar or longer TtD in QoL for ramucirumab + paclitaxel. Treatment with ramucirumab + paclitaxel was also associated with a delay in TtD in PS to ≥2 (HR = 0.798, P = 0.0941). Alternate definitions of PS deterioration yielded similar results: PS ≥ 3 (HR = 0.656, P = 0.0508), deterioration by ≥1 PS level (HR = 0.802, P = 0.0444), and deterioration by ≥2 PS levels (HR = 0.608, P = 0.0063). EQ-5D scores were comparable between treatment arms, stable during treatment, and worsened at discontinuation. CONCLUSION: In patients with previously treated advanced gastric/GEJ adenocarcinoma, addition of ramucirumab to paclitaxel prolonged overall survival while maintaining patient QoL with delayed symptom worsening and functional status deterioration.

RESUMO

BACKGROUND: Systemic chemotherapy typically converts previously unresectable liver metastases (LM) from colorectal cancer to curative intent resection in ∼15% of patients. This European multicenter phase II trial tested whether hepatic artery infusion (HAI) with triplet chemotherapy and systemic cetuximab could increase this rate to 30% in previously treated patients. PATIENTS AND METHODS: Participants had unresectable LM from wt KRAS colorectal cancer. Main non-inclusion criteria were advanced extra hepatic disease, prior HAI and grade 3 neuropathy. Irinotecan (180 mg/m(2)), oxaliplatin (85 mg/m(2)) and 5-fluorouracil (2800 mg/m(2)) were delivered via an implanted HAI access port and combined with i.v. cetuximab (500 mg/m(2)) every 14 days. Multidisciplinary decisions to resect LM were taken after every three courses. The rate of macroscopic complete resections (R0 + R1) of LM, progression-free survival (PFS) and overall survival (OS) were computed according to intent to treat. RESULTS: The patient population consisted of 42 men and 22 women, aged 33-76 years, with a median of 10 LM involving a median of six segments. Up to 3 extrahepatic lesions of <1 cm were found in 41% of the patients. A median of six courses was delivered. The primary end point was met, with R0-R1 hepatectomy for 19 of the 64 previously treated patients, 29.7% (95% confidence interval 18.5-40.9). Grade 3-4 neutropenia (42.6%), abdominal pain (26.2%), fatigue (18%) and diarrhea (16.4%) were frequent. Objective response rate was 40.6% (28.6-52.3). Median PFS and OS reached 9.3 (7.8-10.9) and 25.5 months (18.8-32.1) respectively. Those with R0-R1 hepatectomy had a median OS of 35.2 months (32.6-37.8), with 37.4% (23.6-51.2) alive at 4 years. CONCLUSION: The coordination of liver-specific intensive chemotherapy and surgery had a high curative intent potential that deserves upfront randomized testing.

RESUMO

BACKGROUD: The R98 trial explores the addition of irinotecan to a 5-fluorouracil (5-FU) plus leucovorin (5-FU/LV) adjuvant regimen in optimally resected stages II-III rectal cancers. We report the updated long-term results. Disease-free survival (DFS) was the primary end point. PATIENST AND METHODS: Between March 1999 and December 2005, 357 patients were randomized: 178 in 5-FU/LV and 179 in LV5-FU2 + irinotecan arm. The trial was stratified by control arm: Mayo Clinic regimen or LV5-FU2 regimen. RESULTS: Three hundred and fifty-seven randomized patients were evaluable for efficacy. With a follow-up of 156 months, the DFS was in favour of experimental arm but did not reach statistical significance [hazard ratio (HR) = 0.80, P = 0.154]. The same was observed for overall survival (OS) (HR = 0.87, P = 0.433). The 5-year DFS was 58% in the control arm and 63% in the experimental arm. The 5-year OS was 74% in the control arm and 75% in the experimental arm. Patients allocated to the experimental arm had more grade 3-4 neutropenia when compared with the LV5-FU2 arm (33% versus 6%, P = 0.03), but not when compared with the Mayo Clinic arm (33% versus 36%, P = 0.84). Grade 3-4 diarrhoea tended to be higher in the experimental arm, but analyses stratified by control arm or by radiotherapy failed to show significant differences across strata (test for interaction P = 0.44). CONCLUSION: Even though a benefit of irinotecan in subgroups of patients cannot be excluded, due to early termination and lack of power, the study does not support the addition of irinotecan to 5-FU/LV in routine in patients with resected stage II-III rectal cancer.

RESUMO

BACKGROUND: Docetaxel/cisplatin/infusional 5-fluorouracil (5-FU; DCF) is a standard chemotherapy regimen for patients with advanced gastric cancer (GC). This phase II study evaluated docetaxel/oxaliplatin (TE), docetaxel/oxaliplatin/5-FU (TEF), and docetaxel/oxaliplatin/capecitabine (TEX) in patients with advanced GC. PATIENTS AND METHODS: Patients with metastatic or locally recurrent gastric adenocarcinoma (including carcinoma of the gastro-oesophageal junction) were randomly assigned (1 : 1 : 1) to TE, TEF, or TEX. Each regimen was tested at two doses before full evaluation at optimized dose levels. The primary end point was progression-free survival (PFS). Overall survival (OS), tumour response, and safety were also assessed. A therapeutic index (median PFS relative to the incidence of febrile neutropenia) was calculated for each regimen and compared with DCF (historical data). RESULTS: Overall, 248 patients were randomly assigned to receive optimized dose treatment. Median PFS was longer with TEF (7.66 [95% confidence interval (CI): 6.97-9.40] months) versus TE (4.50 [3.68-5.32] months) and TEX (5.55 [4.30-6.37] months). Median OS was 14.59 (95% CI: 11.70-21.78) months for TEF versus 8.97 (7.79-10.87) months for TE and 11.30 (8.08-14.03) months for TEX. The rate of tumour response (complete or partial) was 46.6% (95% CI 35.9-57.5) for TEF versus 23.1% (14.3-34.0) for TE and 25.6% (16.6-36.4) for TEX. The frequency and type of adverse events (AEs) were similar across the three arms. Common grade 3/4 AEs were fatigue (21%), sensory neuropathy (14%), and diarrhoea (13%). Febrile neutropenia was reported in 2% (TEF), 14% (TE), and 9% (TEX) of patients. The therapeutic index was improved with TEF versus TEX, TE, or DCF. CONCLUSION: These results suggest that TEF is worthy of evaluation as an arm in a phase III trial or as a backbone regimen for new targeted agents in advanced GC.

RESUMO

BACKGROUND: Prognosis of patients with pancreatic adenocarcinoma is poor. Many prognostic biomarkers have been tested, but most studies included heterogeneous patients. We aimed to investigate the prognostic and/or predictive values of four relevant biomarkers in a multicentric cohort of patients. PATIENTS AND METHODS: A total of 471 patients who had resected pancreatic adenocarcinoma were included. Using tissue microarray, we assessed the relationship of biomarker expressions with the overall survival: Smad4, type II TGF-ß receptor, CXCR4, and LKB1. RESULTS: High CXCR4 expression was found to be the only independent negative prognostic biomarker [hazard ratio (HR) = 1.74; P < 0.0001]. In addition, it was significantly associated with a distant relapse pattern (HR = 2.19; P < 0.0001) and was the strongest prognostic factor compared with clinicopathological factors. In patients who did not received adjuvant treatment, there was a trend toward decrease in the overall survival for negative Smad4 expression. Loss of Smad4 expression was not correlated with recurrence pattern but was shown to be predictive for adjuvant chemotherapy (CT) benefit (HR = 0.59; P = 0.002). CONCLUSIONS: CXCR4 is a strong independent prognostic biomarker associated with distant metastatic recurrence and appears as an attractive target to be evaluated in pancreatic adenocarcinoma. Negative SMAD4 expression should be considered as a potential predictor of adjuvant CT benefit.

RESUMO

The article summarizes the expert discussion and recommendations on the use of molecular markers and of biological targeted therapies in metastatic colorectal cancer (mCRC), as well as a proposed treatment decision strategy for mCRC treatment. The meeting was conducted during the 11th ESMO/World Gastrointestinal Cancer Congress (WGICC) in Barcelona in June 2009. The manuscript describes the outcome of an expert discussion leading to an expert recommendation. The increasing knowledge on clinical and molecular markers and the availability of biological targeted therapies have major implications in the optimal management in mCRC.

RESUMO

The time evolution of the postural behavior of 23 lateral ankle sprain patients (degrees I and II) were evaluated 14 h and 10 and 30 days on average after their injury and compared with those of 30 age-matched healthy individuals. The patients were tested with separate measurements of the reaction forces under each limb to highlight the possible compensatory mechanisms between the sound and the injured legs. Their postural behavior in bipedal stance was characterised by a weight-bearing asymmetry with more weight on the sound leg and an asymmetry of the postural stabilisation mechanisms, which are limited and perturbed under the injured leg. Pain appears to be the main factor for explaining these postural asymmetries. Despite these asymmetries, the patients were nonetheless more unstable than the individuals constituting the group control. Ten days later, only the weight-bearing asymmetry was still observed whereas 30 days later, the postural behavior was totally normal once again. Lateral ankle sprain perturbs the contribution of the injured leg in postural stabilisation, inducing a larger involvement of the sound leg in the postural stability process. These characteristics are largely reduced 10 days after the injury.

RESUMO

To investigate the effects induced by wearing an orthosis during the rehabilitation process, 23 ankle sprain patients (degrees I and II) were evaluated in three conditions (reference, with an elastic compression stocking and with an orthosis), 14 h, 10 and 30 days on average after their injury and compared with those of 30 age-matched healthy individuals. The patients were tested with separate measurements of the reaction forces under each limb to highlight the possible compensatory mechanisms between the sound and the injured legs. Their postural stability was enhanced during unilateral orthosis wear, explained by a bilateral effect involving both feet. Wearing a compression stocking induced comparably mild intermediate effects compared with the effects observed with the orthosis. These effects were constant throughout the next month. Following lateral ankle sprain, wearing an orthosis allows patients to improve postural function a few hours after the injury to 1 month later. Only cutaneous pressure intervening without mechanical maintenance induced mild effects, indicating that orthosis effects on postural control could partly result from its sensorial stimulation. It, therefore, seems relevant to prescribe orthosis wear for at least 1 month.

RESUMO

The past 5 years have seen the clear recognition that the administration of chemotherapy to patients with initially unresectable colorectal liver metastases can increase the number of patients who can undergo potentially curative secondary liver resection. Coupled with this, recent data have emerged that show that perioperative chemotherapy confers a disease-free survival advantage over surgery alone in colorectal cancer (CRC) patients with initially resectable liver disease. The purpose of this paper is to build on the existing knowledge and review the issues surrounding the use of chemotherapy +/- targeted agents combined with surgery in the treatment of CRC patients with liver metastases, with a view to providing clinical recommendations. An international panel of 21 experts in colorectal oncology comprising liver surgeons and medical oncologists reviewed the available evidence. In a major change to clinical practice, the panel's recommendation was that the majority of patients with CRC liver metastases should be treated up front with chemotherapy, irrespective of the initial resectability status of their metastases.

RESUMO

This article summarizes the expert discussion on the management of hepatocellular carcinoma (HCC), which took place during the 10th World Gastrointestinal Cancer Congress (WGICC) in Barcelona, June 2008. A multidisciplinary approach to a patient with HCC is essential, to guarantee optimal diagnosis and staging, planning of surgical options and selection of embolisation strategies or systemic therapies. In many patients, the underlying cirrhosis represents a challenge and determines therapeutic options. There is now robust evidence in favour of systemic therapy with sorafenib in patients with advanced HCC with preserved liver function. Those involved in the care for patients with HCC should be encouraged to participate in well-designed clinical trials, to increase evidence-based knowledge and to make further progress.

RESUMO

The prevalence, clinical profiles and management of gastroenteropancreatic endocrine tumours (GEP) in France are not known. From August 1, 2001 to September 1, 2002, standardized records on patients with GEP were prospectively completed in 87 participating centres. The total group amounted to 668 patients (median age: 56 years, range: 12-89). WHO performance status was 0/1 for 80.2% of patients. The primary sites were the small bowel and colon (288), pancreas (211), unknown (77), stomach (33), non-digestive primary sites (24), appendix (20), rectum-anus (12), and oesophagus or cardia (3). GEP were functional in 260 patients (39%). Most pancreatic tumours were non-functional (72%). Metastatic disease was observed in 73.4% of cases. Most tumours (85.8%) were well or moderately differentiated. Somatostatin receptor scintigraphy was performed in only 55% of patients. The following treatment modalities were employed: resection of primary tumour: 66%; systemic chemotherapy: 41%; somatostatin analogues: 44 and 26% for GEP of small intestine and pancreas, respectively; interferon: 12%, and intra-arterial hepatic (chemo)embolization in 23 and 15% of GEP arising from the midgut and pancreas, respectively. Despite their low prevalence, well-differentiated GEP represent a significant and heterogeneous clinical group, which warrants improved medical education, referral to expert centres at an early stage, and the design of prospective therapeutic trials.

RESUMO

In metastatic colorectal cancers (CRC), progress of chemotherapies in 40 years greatly increased their median survival from 6 to 8 months to 20 months. The first step of this development has been: the discovery of 5-fluorouracil, its optimisation by folinic acid and continuous perfusions. In the years 1990 to 2000, oxaliplatin and irinotecan opened the era of polychemotherapies. Their use in fisrt line treatment is not mandatory for all patients for whom chemotherapy may only have a palliative role without need for high response rates as for patients with symptomatic metastases or metastases hardly resectable. Targeted therapies have increased the life expectancy of the metastatic CRC and for some of them to facilitate secondary resections. Bevacizumab, an anti-VEGF antibody, in combination with an irinotecan based regimen increased dramatically the life expectancy with an acceptable toxicity, at least in patients of less than 70 years old. Efficacy of bevacizumab has also been demonstrated in combination with oxaliplatin based regimen (XELOX and FOLFOX) in first and second line, and in combination with 5-fluorouracil alone. Presently, bevacizumab is the most used targeted therapies in first line chemotherapy in combination with FOLFIRI, FOLFOX or XELOX. Cetuximab and panitumumab have first demonstrated their efficacy in the population of fully resistant patients to chemotherapies with a progression free survival gain of about 4 months as single treatment (cetuximab and panitumumab) or combined to irinotecan (cetuximab). Two studies have demonstrated that the adjonction of cetuximab in the first line treatment to FOLFIRI or FOLFOX increased the response rates. The presence of epithelial growth factor receptors (EGFR) at the cell'surface in immunohistochemistry is not a prerequisite for responses to cetuximab and panitumumab, and only patients with tumors without mutation of oncogene KRAS (60% of patients) are able to respond to anti-EGFR. This activity for the KRAS non mutated population has also been demonstrated in patients resistant to chemotherapy, compared to best supportive cases with panitumumab and with cetuximab. Thus, utilisation of anti-EGFR is only authorized in non mutated KRAS tumors and for the first time in metastatic CRC, we have the possibility to enrich the population in selecting non mutated KRAS population and to treat only patients having increased chance of response and of secondary resections of initially non resectable metastases. The cost of these targeted therapies is elevated and we need to find factors which will allow a personalized medicine with the dual selection of the good drug for the right patients.

RESUMO

BACKGROUND: Chemotherapy is effective in metastatic pancreatic adenocarcinoma (PAC), but the benefits of second- and third-line chemotherapy remain unclear. METHODS: We studied all patients followed consecutively for metastatic PAC, and registered at our institution between 1997 and 2006. We retrospectively analyzed the following data in terms of chemotherapy: tumor response; time to tumor progression (TTP) for each line; and overall survival (OS). Efficacy of second-line regimens was assessed using the growth modulation index (GMI). RESULTS: Out of 117 patients, 99 (85%) received at least one line of chemotherapy, 53 (45%) received two lines and 24 (21%) had three or more lines. Median OS was 6.7 months for all 117 patients, 1.8 months for 18 patients who never received chemotherapy, 4.6 months for 46 patients who received one-line chemotherapy and 11.5 months for 53 patients who received at least two lines. Median OS from the beginning of the second-line was 4.7 months. The GMI demonstrated beneficial effects of second-line treatment on disease progression, with a GMI greater than 1.33 in 57% (30/53) of patients. CONCLUSION: More than half the patients with metastatic PAC progression while receiving one-line chemotherapy achieved better disease control on receiving two lines of treatment.

RESUMO

BACKGROUND: Few data are available from clinical trials for elderly patients receiving cetuximab. PATIENTS AND METHODS: The clinical data of consecutive patients aged > or =70 years given cetuximab for metastatic CRC were retrospectively captured from hospital pharmacy registries in seven centers. RESULTS: Fifty-six patients received cetuximab+/-with irinotecan. Median age was 76 years (70-84), 86% of patients were pretreated with fluoropyrimidines, irinotecan and oxaliplatin and 69.6% had documented resistance to irinotecan. Objective response rate was 21% (95% CI: 11-32%). The median progression-free survival was 4.4 months (95% CI: 3.0-5.7 months) and the median overall survival was 16.0 months (95% CI: 13.5-18.5 months). Skin rash occurred in 75% of the patients (11% grade 3) and diarrhea in 80% (20% grades 3-4). CONCLUSION: Tolerability of cetuximab was acceptable in elderly patients with pretreated metastatic CRC. Efficacy appeared similar to that observed in younger patients.

RESUMO

BACKGROUND: The role of chemoradiation with systemic chemotherapy compared with chemotherapy alone in locally advanced pancreatic cancer (LAPC) is uncertain. PATIENTS AND METHODS: One hundred and nineteen patients with LAPC, World Health Organization performance status of zero to two were randomly assigned to either the induction CHRT group (60 Gy, 2 Gy/fraction; concomitant 5-fluorouracil infusion, 300 mg/m(2)/day, days 1-5 for 6 weeks; cisplatin, 20 mg/m(2)/day, days 1-5 during weeks 1 and 5) or the induction gemcitabine group (GEM: 1000 mg/m(2) weekly for 7 weeks). Maintenance gemcitabine (1000 mg/m(2) weekly, 3/4 weeks) was given in both arms until disease progression or toxicity. RESULTS: Overall survival was shorter in the CHRT than in GEM arm [median survival 8.6 (99% confidence interval 7.1-11.4) and 13 months (8.7-18.1), P = 0.03]. One-year survival was, respectively, 32% and 53%. These results were confirmed in a per-protocol analysis for patients who received 75% or more of the planned dose of radiotherapy. More overall grades 3-4 toxic effects were recorded in the CHRT arm, both during induction (36 versus 22%) and maintenance (32 versus 18%). CONCLUSION: This intensive induction schedule of CHRT was more toxic and less effective than gemcitabine alone.

RESUMO

OBJECTIVE: The objective of this study was to assess the performance of three staging systems [Okuda, Cancer of the Liver Italian Program (CLIP) and Barcelona Clinic Liver Cancer group (BCLC)], for predicting survival in patients with hepatocellular carcinoma (HCC) and to explore how to improve prognostic classification among French patients with HCC whose main etiology is alcoholic cirrhosis. METHODS: We have pooled two randomized clinical trials in palliative condition from the Fédération Francophone de Cancerologie Digestive. They had included 416 and 122 patients. Performances of Okuda, CLIP and BCLC scores have been compared using Akaike information criterion, discriminatory ability (Harrell's C and the Royston's D statistics), monotonicity of gradients and predictive accuracy (Schemper statistics Vs). To explore how to improve classifications, univariate and multivariate Cox model analyses were carried out. RESULTS: The pooled database included 538 patients. The median survival was 5.3 months (95% confidence interval 4.6-6.2). For all statistics CLIP staging system had a better prognostic ability. Performances of all staging systems were rather disappointing. World Health Organization performance status (WHO PS) for CLIP or alpha-fetoprotein for BCLC allowed a significant improvement of prognostic information. CONCLUSION: Our results indicate that CLIP staging seems to be most adapted to palliative setting and that it could be better by associating WHO PS.

RESUMO

Knowledge of the biology and management of rectal cancer continues to improve. A multidisciplinary approach to a patient with rectal cancer by an experienced expert team is mandatory, to assure optimal diagnosis and staging, surgery, selection of the appropriate neo-adjuvant and adjuvant strategy and chemotherapeutic management. Moreover, optimal symptom management also requires a dedicated team of health care professionals. The introduction of total mesorectal excision has been associated with a decrease in the rate of local failure after surgery. High quality surgery and the achievement of pathological measures of quality are a prerequisite to adequate locoregional control. There are now randomized data in favour of chemoradiotherapy or short course radiotherapy in the preoperative setting. Preoperative chemoradiotherapy is more beneficial and has less toxicity for patients with resectable rectal cancer than postoperative chemoradiotherapy. Furthermore chemoradiotherapy leads also to downsizing of locally advanced rectal cancer. New strategies that decrease the likelihood of distant metastases after initial treatment need be developed with high priority. Those involved in the care for patients with rectal cancer should be encouraged to participate in well-designed clinical trials, to increase the evidence-based knowledge and to make further progress. Health care workers involved in the care of rectal cancer patients should be encouraged to adopt quality control processes leading to increased expertise.

RESUMO

The FFCD 9402 multicentre phase III trial was designed to compare the effects of the combination of Transarterial Lipiodol Chemoembolisation (TACE) and tamoxifen with tamoxifen alone on overall survival and quality of life in the palliative treatment of hepatocellular carcinoma with cirrhosis. From 1995 to 2002, 138 patients were randomised between the two groups. One hundred and twenty three patients were eligible including 61 in the Tamoxifen group and 62 in the TACE group. Baseline characteristics were similar: Child-Pugh class A: 70%, alcoholic cirrhosis: 76%, Okuda stage I: 71%, multinodular tumour: 70% and segmental portal vein thrombosis: 10%. At 2years, the overall survival was 22% and 25% in the Tamoxifen and TACE groups (P=.68), respectively. Multivariate analysis identified four independent prognostic factors for survival: alpha-fetoprotein (AFP)>400ng/mL (P=.008), abdominal pain (P=.011), hepatomegaly (P=.023) and Child-Pugh score (P=.032). The Spitzer Index level assessing the quality of life during follow-up did not differ between the two groups (P=.70). Amongst patients with stage Okuda I, the 2-year overall survival was 28% in the Tamoxifen group and 32% in the TACE group (P=.58). In this subgroup, two prognostic factors were statistically significant for survival: AFP>400ng/mL (P=.004) and Spitzer Index (P=.013) as shown by multivariable analysis. In conclusion, this study suggests that TACE improves neither the survival nor the quality of life in patients with HCC and cirrhosis.
