Article: Iron deficiency: From diagnosis to treatment.
[show abstract] [hide abstract]
ABSTRACT: Iron deficiency is the most frequent cause of anaemia worldwide. It impairs quality of life, increases asthenia and can lead to clinical worsening of patients. In addition, iron deficiency has a complex mechanism whose pathologic pathway is recently becoming better understood. The discovery of hepcidin has allowed a better clarification of iron metabolism regulation. Furthermore, the ratio of concentration of soluble transferrin receptor to the log of the ferritin level, has been developed as a tool to detect iron deficiency in most situations. The cause of iron deficiency should always be sought because the underlying condition can be serious. This review will summarize the current knowledge regarding diagnostic algorithms for iron deficiency anaemia. The majority of aetiologies occur in the digestive tract, in men and postmenopausal women, and justify morphological examination of the gut. First line investigations are upper gastrointestinal endoscopy and colonoscopy, and when negative, the small bowel should be explored; newer tools such as video capsule endoscopy have also been developed. The treatment of iron deficiency is aetiological if possible and iron supplementation whether in oral or in parenteral form. New parenteral formulations are available and seem to have promising results in terms of efficacy and safety.Digestive and Liver Disease 04/2013; · 3.05 Impact Factor -
Article: Does endoscopic mucosal resection for large colorectal polyps allow ambulatory management?
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Endoscopic mucosal resection (EMR) is an efficacious endoscopic therapy for large adenoma or confined neoplasia. The most frequent complication is delayed hemorrhage, and hemoclips appear to be an effective therapeutic option. The aim of this study was to determine if large EMR could allow ambulatory management. METHODS: Colorectal polyps ≥20 mm in size treated by EMR in one endoscopy unit were prospectively included. The period from September 2007 to September 2008 was considered as the reference period (period 1). From September 2008 on, patients were hospitalized in an ambulatory unit. Periods from September 2008 to September 2009 (period 2), from September 2009 to September 2010 (period 3), and from September 2010 to September 2011 (period 4) were compared to the reference period. Patients receiving anticoagulation drugs were excluded from the study. RESULTS: A total of 138 patients were treated by 139 EMRs for large colorectal polyps. EMRs were completed by at least one clip per centimeter in 10.7 %, 30.2 % (p = NS), 50 % (p = 0.015), and 76 % (p = 0.001). Ambulatory EMRs were performed in 21 %, 52.4 % (p = 0.008), 67.6 % (p = 0.02), and 88.2 % (p = 0.004) of cases during periods 1, 2, 3, and 4. The complication rate was stable during the four periods. No patients with more than one hemoclip per EMR centimeter experienced delayed bleeding. CONCLUSIONS: The low complication rate during the four periods allows us to consider ambulatory EMR for large colorectal lesions ≥20 mm in diameter as an option. One hemoclip per centimeter may help prevent delayed hemorrhage in patients without anticoagulation drugs.Surgical Endoscopy 02/2013; · 4.01 Impact Factor -
Article: Cervical extravasation of bevacizumab.
[show abstract] [hide abstract]
ABSTRACT: Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective.Anti-cancer drugs 12/2012; · 2.23 Impact Factor -
Article: Feasibility of Gemcitabine plus Oxaliplatin in Advanced Hepatocellular Carcinoma Patients with Child-Pugh B Cirrhosis.
[show abstract] [hide abstract]
ABSTRACT: Purpose: Sorafenib improves survival in advanced hepatocellular carcinoma (HCC), but the demonstration of its efficacy and safety is limited to Child-Pugh A cirrhotic patients. The biweekly combination of gemcitabine and oxaliplatin (GEMOX) is safe and widely used in patients with advanced malignancies. We aimed to evaluate the feasibility of GEMOX in HCC patients with Child-Pugh B cirrhosis ineligible for sorafenib. Methods: The medical records of cirrhotic patients with advanced HCC receiving the GEMOX regimen between July 2006 and November 2011 were retrospectively reviewed. Treatment was repeated every 2 weeks until disease progression or unacceptable adverse effects occurred. The primary evaluation criterion was safety. Secondary evaluation criteria were the presence of muscle wasting (sarcopenia), response rate, progression-free survival and overall survival (OS). Results: Patients with Child-Pugh A (group A, n = 17) or Child-Pugh B cirrhosis (group B, n = 15) received a total of 169 cycles (median 4, range 1-16/patient). Eight patients in each group had sarcopenia. Common toxicities were thrombocytopenia (25 and 14 in groups A and B, respectively; p = 0.65) and peripheral neuropathy (44 and 54% in groups A and B, respectively; p = 1). Neither febrile neutropenia nor toxic death occurred. One patient in each group experienced grade 3 oesophageal varices bleeding. The response and disease control rates were 18% (95% CI 0-35.8) and 58.8% (95% CI 35.4-82.2) in group A, and 27% (95% CI 4.3-49.1) and 60.0% (95% CI 35.2-84.8) in group B. The median progression-free survival and OS did not differ between the two groups, but median OS was significantly shorter in sarcopenic patients. Conclusions: The GEMOX regimen appears feasible in HCC patients with Child-Pugh B cirrhosis and exerts anti-tumour activity. These data need to be confirmed in a prospective study.Oncology 10/2012; 84(1):32-38. · 2.27 Impact Factor -
Article: [Neuroendocrine pancreatic tumors and helpfulness of targeted therapies.]
[show abstract] [hide abstract]
ABSTRACT: The neuroendocrine pancreatic tumors are rare tumors, but their incidence is constantly rising. Even if the management of these tumors has to be surgical as soon as possible, the disease is most often metastatic at the stage of the diagnostic. The prognostic and the therapeutic options differ from pancreatic adenocarcinoma. Available treatments have evolved over the last years with recent publications of studies that bring to light the benefits of targeted therapies in this pathology. This has resulted in modifications of both practices and either French and international guidelines. Therefore, we focus on the management of the grade 1 and grade 2 well-differentiated neuroendocrine pancreatic tumors as classified in new WHO classification of neuroendocrine neoplasms published in 2010.La Presse Médicale 09/2012; · 0.67 Impact Factor -

Article: [Achalasia: Role of endoscopic therapy and surgery.]
[show abstract] [hide abstract]
ABSTRACT: Pneumatic dilation of achalasia has a same medium-term efficacy than surgery and is commonly proposed as the first-line treatment. Intra-sphincteric injection of botulinum toxin is reserved for elderly patients with serious comorbidities. Per-endoscopic myotomy is possible but needs to be evaluated by further studies. Laparoscopic Heller's myotomy in first intension is reserved for young patients less than 40 years. Results of Heller's myotomy are not modified by prior endoscopic treatment or by mega-esophagus. Better surgery results are shown in recent and severe achalasia.La Presse Médicale 09/2012; · 0.67 Impact Factor -
Article: Sorafenib-induced hepatocellular carcinoma cell death depends on reactive oxygen species production in vitro and in vivo.
[show abstract] [hide abstract]
ABSTRACT: Sorafenib is presently the only effective therapy in advanced hepatocellular carcinoma (HCC). Because most anticancer drugs act, at least in part, through the generation of reactive oxygen species, we investigated whether sorafenib can induce an oxidative stress. The effects of sorafenib on intracellular ROS production and cell death were assessed in vitro in human (HepG2) and murine (Hepa 1.6) HCC cell lines and human endothelial cells (HUVEC) as controls. In addition, 26 sera from HCC patients treated by sorafenib were analyzed for serum levels of advanced oxidation protein products (AOPP). Sorafenib significantly and dose-dependently enhanced in vitro ROS production by HCC cells. The SOD mimic MnTBAP decreased sorafenib-induced lysis of HepG2 cells by 20% and of Hepa 1.6 cells by 75% compared with HCC cells treated with 5 mg/L sorafenib alone. MnTBAP significantly enhanced by 25% tumor growth in mice treated by sorafenib. On the other hand, serum levels of AOPP were higher in HCC patients treated by sorafenib than in sera collected before treatment (P < 0.001). An increase in serum AOPP concentration ≥0.2 μmol/L chloramine T equivalent after 15 days of treatment is a predictive factor for sorafenib response with higher progression free survival (P < 0.05) and overall survival rates (P < 0.05). As a conclusion, sorafenib dose-dependently induces the generation of ROS in tumor cells in vitro and in vivo. The sera of Sorafenib-treated HCC patients contain increased AOPP levels that are correlated with the clinical effectiveness of sorafenib and can be used as a marker of effectiveness of the drug.

Article: A rare hematological adverse event induced by bevacizumab: severe thrombocytopenia.
[show abstract] [hide abstract]
ABSTRACT: Bevacizumab, a monoclonal antibody to vascular endothelial growth factor-A, is approved for the treatment of various malignancies, and its hematological toxicities are considered infrequent. A colorectal cancer patient receiving chemotherapy (5-fluorouracil and oxaliplatin) plus bevacizumab developed acute, severe thrombocytopenia. We postulated that this thrombocytopenia could be directly triggered by bevacizumab. A man with stage IV colorectal cancer and synchronous liver metastasis had received 10 cycles of FOLFOX plus bevacizumab (5 mg/kg) without significant hematological toxicity. Due to thrombocytopenia, oxaliplatin was withdrawn after cycle 11. On cycle 12, shortly after bevacizumab infusion and before 5-fluorouracil infusion, the patient developed fever, lower limbs purpura, grade 1 proctorrhagia, and epistaxis. Platelets had decreased from 105,000/mm(3) to 3000/mm(3) within 1 hour after bevacizumab infusion. Flow cytometry identified platelet-associated immunoglobulins. Despite 2 apheresis-derived platelet transfusions, oral corticotherapy, and gamma globulin infusions, thrombocytopenia persisted, but was finally successfully treated with a peptibody thrombopoietin mimetic, which was introduced 28 days after the last bevacizumab infusion. Clinicians should keep in mind that bevacizumab can induce acute and potentially severe immune-mediated thrombocytopenia.The American journal of medicine 08/2012; 125(8):828-30. · 4.47 Impact Factor -
Article: Variability of Sorafenib Toxicity and Exposure over Time: A Pharmacokinetic/Pharmacodynamic Analysis.
[show abstract] [hide abstract]
ABSTRACT: Background. Sorafenib displays major interpatient pharmacokinetic variability. It is unknown whether the pharmacokinetics of sorafenib influence its toxicity. Methods. We analyzed the severity and kinetics of sorafenib-induced toxicities in unselected consecutive patients with cancer, as well as their relationship with biological, clinical, and pharmacokinetic parameters. Toxicity was recorded bimonthly. Sorafenib plasma concentrations were assessed by liquid chromatography. Results. For 83 patients (median age, 62 years; range, 21-84 years), median sorafenib 12-hour area under the curve (AUC(0-12)) was 52.8 mg · h/L (range: 11.8-199.6). A total of 51 patients (61%) experienced grade 3-4 toxicities, including hand-foot skin reactions (23%), asthenia (18%), and diarrhea (11%). Sorafenib AUC(0-12) preceding grade 3-4 toxicities was significantly higher than that observed in the remaining population (61.9 mg · h/L vs. 53 mg · h/L). In 25 patients treated with fixed doses of sorafenib for the first 4 months, median dose-normalized AUC(0-12) on day 120 was significantly lower than on day 15 (63 vs. 102 mg · h/L). The incidence of hypertension and hand-foot skin reactions significantly decreased over time. Conclusion. Sorafenib AUC(0-12) decreases over time, similarly to the incidence of hypertension and hand-foot skin reactions. Monitoring of sorafenib plasma concentrations may help to prevent acute severe toxicities and detect patients with suboptimal exposure at disease progression.The Oncologist 07/2012; 17(9):1204-12. · 3.91 Impact Factor -
Article: Cost effectiveness of integrated medicine in patients with cancer receiving anticancer chemotherapy.
[show abstract] [hide abstract]
ABSTRACT: Ambulatory chemotherapy is patient friendly but may result in toxicity-induced unscheduled hospitalizations (TIUHs). This emerging issue may increase health care costs. We studied the cost effectiveness of a hospital-home monitoring program based on systematic iterative telephone calls after chemotherapy. We retrospectively evaluated the rates of chemotherapy-induced unscheduled hospitalizations in patients who were treated in August 2008. Patients were contacted by telephone 1 day before chemotherapy and on the second and eighth days after undergoing chemotherapy. Costs associated with TIUHs were calculated and compared with those of a cohort concomitantly treated using the standard follow-up procedure. A total of 259 patients entered the hospital-home monitoring program. They were compared with 86 patients who had similar characteristics but underwent the standard treatment and follow-up procedure. Inclusion in the hospital-home monitoring program resulted in patients experiencing TIUHs approximately half as frequently as patients in the other group (2.4% v 4.9%; P < .01). Patients in the program experienced TIUHs for a median length of stay of 4 days, representing a nonsignificant reduction in duration of hospitalization (P not significant). Consequently, through a two-fold reduction in TIUH annual incidence, this program represents a reduction in unscheduled hospitalizations per year of 383 days, decreasing hospital costs by €201.468 ($292,468) per year. The hospital-home monitoring program is a cost-effective strategy for offering ambulatory chemotherapy treatment to patients with cancer. This program has become our standard procedure for ambulatory chemotherapy in patients with cancer.Journal of Oncology Practice 07/2012; 8(4):205-10. -
Article: Feasibility of gemcitabine and oxaliplatin in patients with advanced biliary tract carcinoma and a performance status of 2.
[show abstract] [hide abstract]
ABSTRACT: The use of gemcitabine and oxaliplatin is well documented in selected patients with advanced biliary tract carcinoma (BTC), but little is known on the feasibility of systemic treatments in patients with a performance status (PS) of 2. We retrospectively examined the medical records of consecutive BTC patients with a PS of 2 receiving gemcitabine 1000 mg/m(2) plus oxaliplatin 100 mg/m(2) every 2 weeks from January 2003 to December 2011 in our institution. Body composition was analysed by computed tomography scan to detect sarcopenia. The primary evaluation criterion was safety. The secondary evaluation criteria were the response rate, progression-free survival (PFS) and overall survival (OS). Twenty-eight patients (median age: 63 years, range 41-83) received a total of 175 cycles (median per patient: 6, range 2-12). Ten patients (35.7%) had sarcopenia on the pretreatment computed tomography scan. The most frequent toxicities were thrombocytopenia (grades 2-4: n=4, 14.3%), peripheral neuropathy (grades 2-3: n=9, 32.1%) and cholangitis (n=4, 14.3%). The best response was a partial response in 10.7% of patients [95% confidence interval (CI): 0-22.2] and stable disease in 42.9% of patients. The median PFS and OS were 4.6 (95% CI: 2.5-6.3) and 7.5 (95% CI: 5.2-9.5) months, respectively. The median PFS and OS were significantly longer in patients without sarcopenia: 7.0 months (95% CI: 4.4-8.0) vs. 2.2 months (95% CI: 2.0-2.5), P less than 0.01, and 10.4 months (95% CI: 7.5-11.6) vs. 4.9 months (95% CI: 3.7-5.2), P less than 0.01, respectively. In our experience, gemcitabine-oxaliplatin was feasible and induced effective palliation in PS2 patients with advanced BTC. Further studies are warranted to confirm these findings.Anti-cancer drugs 06/2012; 23(7):739-44. · 2.23 Impact Factor -
Article: Interaction between serotonin reuptake inhibitors, 5-HT3 antagonists, and NK1 antagonists in cancer patients receiving highly emetogenic chemotherapy: a case-control study.
[show abstract] [hide abstract]
ABSTRACT: Previous reports suggested that selective serotonin reuptake inhibitors (SSRI) could decrease the activity of 5-hydroxytryptamine type 3 (5-HT3) antagonists against acute chemotherapy-induced nausea and vomiting (CINV), possibly through serotonin accumulation for 5-HT3 receptors. Chemonaive cancer patients receiving SSRI and antiemetic agents, including the 5-HT3 antagonist ondansetron and the neurokinin 1 (NK1) antagonist aprepitant for highly emetogenic chemotherapy (etoposide-platinum), were matched to control patients for the following variables: age, gender, primary tumor, past history of gestational emesis, chronic intake of benzodiazepines and/or corticosteroids, chronic alcohol intake, and aprepitant use. The primary evaluation criterion was the occurrence of acute vomiting during the first two cycles of treatment. Forty-four patients were eligible for this analysis. The proportion of patients, who experienced at least one episode of grade ≥ 1 acute vomiting in patients receiving SSRI, compared to patients who did not, was significantly higher (59.1 vs. 22.7%, respectively, p = 0.03, odds ratio 4.72, 95% confidence interval 1.13-22.88). Grade ≥ 2 acute vomiting was also significantly more frequent in patients receiving SSRI, even after the implementation of aprepitant to antiemetic prophylaxis (41.2 vs. 5.9%, p = 0.04). Our findings reinforce the hypothesis that SSRI decrease the antiemetic activity of the 5-HT3 serotonin antagonist ondansetron, resulting in higher rates of acute vomiting in cancer patients despite adequate antiemetic prophylaxis. Adding the NK1 antagonist aprepitant do not counterbalance the deleterious effect of SSRI, probably due to the synergistic effects of SSRI and NK1 antagonists on serotonin transmission.Supportive Care in Cancer 05/2012; 20(9):2235-9. · 2.09 Impact Factor -
Article: Prognostic Scoring Systems for Spinal Metastases in the Era of Anti-VEGF Therapies.
[show abstract] [hide abstract]
ABSTRACT: Study Design. Spine Update on prognostic scoring systems for spinal metastases in the era of anti-VEGF therapies.Objective. To review and discuss the strengths and weaknesses of available scoring systems since the introduction of molecular targeted anticancer agents.Summary of Background Data. Molecular targeted anticancer agents have dramatically improved survival in various cancers, including renal cancer.Methods. Using prognostic scoring systems for spinal metastases and recent survival data in cancers treated with anti-VEGF agents, a review was undertaken, evaluatingthe strengths and weaknesses of available prognostic scoring systems designed in the 1990s and early 2000s in patients treated with recent agents (available from 2005).Results. All available prognostic scoring systems for spinal metastases include the primary tumour as a key variable. The estimation of life expectancy with these systems is inaccurate in view of recent survival data, as illustrated in renal cancer. The underestimation of life expectancy and subsequent inadequate treatment of spinal metastases may lead to dramatic alteration of the quality of life.Conclusions. The assessment of the available scores in recent cohorts of patients is mandatory in order to test their current validity, and evidence the need for aggressive surgical management. New scoring systems taking into account the gain in survival induced by recent anti-cancer agents will likely be warranted in a close future.Spine 05/2012; · 2.08 Impact Factor -
Article: Helpfulness of the combination of acetic acid and FICE in the detection of Barrett's epithelium and Barrett's associated neoplasias.
[show abstract] [hide abstract]
ABSTRACT: To investigate the mucosal morphology in Barrett's oesophagus by chromo and magnifying endoscopy. A prospective pilot study at a tertiary medical centre was conducted to evaluate the use of acetic acid pulverisation combined with virtual chromoendoscopy using Fujinon intelligent chromoendoscopy (FICE) for semiological characterization of the mucosal morphology in Barrett's oesophagus and its neoplastic complications. Upper endoscopy using high definition white light, 2% acid acetic pulverisation and FICE with high definition videoendoscopy were performed in 20 patients including 18 patients who presented with aspects of Barrett's oesophagus at endoscopy examination. Two patients used as controls had normal endoscopy and histological results. Prospectively, videos were watched blind from histological results by three trained FICE technique endoscopists. The videos of patients with high-grade dysplasia showed an irregular mucosal pattern in 14% using high definition white light endoscopy and in 100% using acid acetic-FICE combined. Videos did not identify irregular vascular patterns using high definition white light endoscopy, while acid acetic-FICE combined visualised one in 86% of cases. Combined acetic acid and FICE is a promising method for screening high-grade dysplasia and early cancer in Barrett's oesophagus.World Journal of Gastroenterology 04/2012; 18(16):1921-5. · 2.47 Impact Factor -
Article: Gemcitabine and oxaliplatin as second-line treatment in patients with hepatocellular carcinoma pre-treated with sorafenib.
[show abstract] [hide abstract]
ABSTRACT: Some patients with advanced hepatocellular carcinoma (HCC) progressing under sorafenib remain eligible for further systemic therapy. Little is known on the feasibility of systemic treatment beyond sorafenib in this setting. Consecutive HCC patients pre-treated with sorafenib received gemcitabine 1,000 mg/m² and oxaliplatin 100 mg/m² every 14 days. Exclusion criteria included Child C cirrhosis, PS ≥ 3, creatinine clearance <20 ml/min, albumin <25 g/L and bilirubin > 54 μmol/L. Pre-treatment body composition was evaluated by CT scan to detect muscle wasting (sarcopenia). The primary evaluation criterion was safety. Secondary evaluation criteria were response rate, and progression-free (PFS) and overall survival (OS). Eighteen patients (median age: 64 years, range 25-77) received a total of 90 cycles (median per patient: 4, range 1-16). Eight patients (44.4 %) had a PS of 2, 5 (27.8 %) had Child-Pugh B cirrhosis and 13 (72.2 %) had a CLIP score >3. The most frequent toxicities were thrombocytopenia (grade 2-4: n = 7, 38.9 %) and peripheral neuropathy (grade 2-3: n = 7, 38.9 %). The overall response rate was 18.8 % (95 % CI: 0-37.9), and another 18.8 % of patients had stable disease. The median PFS and OS were 3.2 (95 % CI: 2.3-3.9) and 4.7 (95 % CI: 3.8-8.1) months, respectively. Overall survival was significantly longer in patients without sarcopenia [10.0 months (95 % CI: 7.0-13.8) vs. 3.0 months (95 % CI: 2.5-3.9), p < 0.001] and in patients with an ECOG PS < 2 [8.1 months (95 % CI: 7.0-13.8) vs. 3.8 months (95 % CI: 2.5-3.9), p = 0.017]. In our experience, gemcitabine-oxaliplatin was feasible and had detectable clinical activity in HCC patients pre-treated with sorafenib. Further studies are needed to confirm these findings.Medical Oncology 03/2012; 29(4):2793-9. · 2.14 Impact Factor -
Article: Pemetrexed, oxaliplatin and bevacizumab as first-line treatment in patients with stage IV non-small cell lung cancer.
[show abstract] [hide abstract]
ABSTRACT: Oxaliplatin has less haematological toxicity than cisplatin and carboplatin. The combination of pemetrexed, oxaliplatin and bevacizumab appeared well tolerated and active as second- or third-line treatment in a previous phase II study. Its role as first-line therapy remains to define. From August 2008 to May 2011, consecutive chemo-naïve patients with stage IV non-squamous non-small cell lung cancer (NSCLC) received pemetrexed 500mg/m(2), oxaliplatin 100mg/m(2) and bevacizumab 7.5mg/kg every 3 weeks for 6 cycles, in the outpatient setting. Maintenance therapy including pemetrexed and bevacizumab was given to patients with non-progressive disease. The primary evaluation criterion was safety. Secondary evaluation criteria were response rate, progression-free survival (PFS) and overall survival (OS). Thirty-eight patients (50% males, median age: 55 years, range 38-76) received a total of 199 cycles (median per patient: 6, range 2-6), plus 98 cycles of maintenance therapy. Twenty patients (52.6%) had a PS of 2, and 6 (15.8%) had brain metastases. The most frequent toxicities were hypertension (all grades: 42.1%) and peripheral neuropathy (grade 2-3: 21.1%). Haematological toxicities included grade 4 neutropenia, grade 3 anaemia and thrombopenia (5.3% each). Neither febrile neutropenia nor arterial thrombo-embolic event occurred. The objective response rate was 55.3% (95%CI: 39.5-71.1). The median PFS and OS were 6.2 (95%CI: 5.4-9.0) and 14.6 (95%CI: 9.8-19.5) months, respectively. In this single centre experience, the combination of pemetrexed, oxaliplatin and bevacizumab was well tolerated and had promising activity as first-line therapy in unselected patients with stage IV non-squamous NSCLC.Lung cancer (Amsterdam, Netherlands) 02/2012; 77(1):104-9. · 3.14 Impact Factor -
Article: Feasibility of oxaliplatin, 5-fluorouracil and leucovorin (FOLFOX-4) in cirrhotic or liver transplant patients: experience in a cohort of advanced hepatocellular carcinoma patients.
[show abstract] [hide abstract]
ABSTRACT: The only drug that improves survival in hepatocellular carcinoma is sorafenib. FOLFOX-4 regimen is safe and widely used in patients with colorectal cancer, yielding interesting results with little toxicity. We conducted a retrospective study to evaluate the safety and the effectiveness of FOLFOX-4 in cirrhotic or liver transplanted patients with hepatocellular carcinoma ineligible for sorafenib. Thirty seven patients were enrolled in the study. The medical record of either cirrhotic patients or liver transplanted patients with advanced hepatocellular carcinoma receiving FOLFOX-4 regimen between November 1999 and March 2006 were retrospectively analyzed. Patients received oxaliplatin 85 mg/m(2) as a 2-hour infusion on day one, and leucovorin 200 mg/m(2) as a 2-hour infusion followed by bolus 5-fluorouracil 400 mg/m(2) and a 48-hours infusion of 5-fluorouracil 2400 mg/m(2). Treatment was repeated every 2 weeks until disease progression or unacceptable adverse effects occurred. Patients had a Child-Pugh class A (n = 16), class B cirrhosis (n = 10) or a liver transplant (n = 11) and received 2 to 37 cycles of chemotherapy (total of 310 cycles). Two (5.4%) cirrhotic patients developed neutropenic sepsis and one (2.7%) toxic death occurred. At first assessment, five patients from Child-Pugh class A (33%) and two from Child-Pugh class B group (20%) achieved a radiological response and/or alpha foeto-protein decrease, and no patient achieved a complete response. In conclusion, with a manageable toxicity profile in cirrhotic Child-Pugh class A-B or liver transplanted patients, the FOLFOX-4 regimen appears to be a feasible treatment option for patients with advanced hepatocellular carcinoma unfit for sorafenib. These data need to be confirmed in a prospective study.Investigational New Drugs 02/2012; 30(1):376-81. · 3.36 Impact Factor -
Article: Sarcopenia predicts early dose-limiting toxicities and pharmacokinetics of sorafenib in patients with hepatocellular carcinoma.
[show abstract] [hide abstract]
ABSTRACT: Sorafenib induces frequent dose limiting toxicities (DLT) in patients with advanced hepatocellular carcinoma (HCC). Sarcopenia has been associated with poor performance status and shortened survival in cancer patients. The characteristics of Child Pugh A cirrhotic patients with HCC receiving sorafenib in our institution were retrospectively analyzed. Sorafenib plasma concentrations were determined at each visit. Toxicities were recorded during the first month of treatment, and sarcopenia was determined from baseline CT-scans. Forty patients (30 males) were included. Eleven (27.5%) were sarcopenic. Eighteen patients (45%) experienced a DLT during the first month of treatment. Sarcopenic patients experienced significantly more DLTs than non-sarcopenic patients did (82% versus 31%, p = 0.005). Grade 3 diarrhea was significantly more frequent in sarcopenic patients than in non-sarcopenic patients (45.5% versus 6.9%, p = 0.01), but not grade 3 hand foot syndrome reaction (9% versus 17.2%, p = 1). On day 28, median sorafenib AUC (n = 17) was significantly higher in sarcopenic patients (102.4 mg/l.h versus 53.7 mg/l.h, p = 0.013). Among cirrhotic Child Pugh A patients with advanced HCC, sarcopenia predicts sorafenib exposure and the occurrence of DLT within the first month of treatment.PLoS ONE 01/2012; 7(5):e37563. · 4.09 Impact Factor
