    ABSTRACT: Background: The present monocentric and prospective phase 1 study evaluated the safety of a metronomic chemotherapy in refractory tumors. Patients and Methods: Patients with advanced solid cancer refractory to standard therapy received a combination of low-dose vinorelbine, cyclophosphamide and interferon-alpha. A dose escalation model with 3 levels was planned. The primary end-point was safety and tolerability, secondary end-points were treatment continuation rate at 4 months, progression-free survival (PFS), overall survival (OS), radiological assessment (MRI) of anti-angiogenic effect. Results: Thirty patients were enrolled. No dose-limiting toxicity was observed. All but two adverse events were toxicities of grade 1-2. Treatment continuation rate at 4 months was 6.67% (2 out of 30 patients). Median PFS and OS were 1.6 and 6.1 months. Exploratory MRI analyses related to anti-angiogenic effect did not show any relevant modification. Conclusion: This combination of metronomic chemotherapy is well-tolerated and deserves to be deeply explored in refractory solid tumors.

    ABSTRACT: The combination of an anti-VEGF or an anti-EGFR-targeted monoclonal antibody with chemotherapy has shown clinical activity in patients with metastatic colorectal cancer. However, combining both anti-VEGF and anti-EGFR antibodies with chemotherapy in first-line treatment resulted in adverse outcomes. We assessed whether the combination of erlotinib, an EGFR tyrosine kinase inhibitor, with bevacizumab could increase the efficacy of maintenance therapy in patients with unresectable metastatic colorectal cancer.

    ABSTRACT: Background We performed a randomized, non-comparative phase II study evaluating docetaxel in combination with either daily continuous (protracted IV) 5-fluorouracil or cisplatin administered weekly, concurrent to radiotherapy in the treatment of locally advanced pancreatic carcinoma. Results of the docetaxel plus cisplatin regimen are reported. Methods Forty chemotherapy-naive patients with locally advanced pancreatic carcinoma were randomly assigned to receive 5-fluorouracil and docetaxel or docetaxel 20 mg/m2 and cisplatin 20 mg/m2/week, plus concurrent radiotherapy for 6 weeks. The radiation dose to the primary tumour was 54 Gy in 30 fractions. The trial's primary endpoint was the 6-month crude non-progression rate. Results 51 patients from 7 centres were included in the docetaxel–cisplatin treatment group. Six-month non-progression rate was 39% (95% confidence interval: 26–53). Median overall survival was 9.6 months (95% confidence interval: 2.4–60.7); 6 complete and 8 partial responses were obtained. Six patients survived more than 2 years after their inclusion in the trial. Grade ≥3 toxicity was reported in 63% of patients; no treatment-related death occurred. Severe toxicities were mainly anorexia (22%), vomiting (20%) and fatigue (24%). Conclusions Despite inadequate efficacy according to the main end point, this regimen gave a satisfactory rate of objective response (27%) with tolerable toxicity.

    ABSTRACT: Background Gemcitabine plus a platinum-based agent (eg, cisplatin or oxaliplatin) is the standard of care for advanced biliary cancers. We investigated the addition of cetuximab to chemotherapy in patients with advanced biliary cancers. Methods In this non-comparative, open-label, randomised phase 2 trial, we recruited patients with locally advanced (non-resectable) or metastatic cholangiocarcinoma, gallbladder carcinoma, or ampullary carcinoma and a WHO performance status of 0 or 1 from 18 hospitals across France and Germany. Eligible patients were randomly assigned (1:1) centrally with a minimisation procedure to first-line treatment with gemcitabine (1000 mg/m2) and oxaliplatin (100 mg/m2) with or without cetuximab (500 mg/m2), repeated every 2 weeks until disease progression or unacceptable toxicity. Randomisation was stratified by centre, primary site of disease, disease stage, and previous treatment with curative intent or adjuvant therapy. Investigators who assessed treatment response were not masked to group assignment. The primary endpoint was the proportion of patients who were progression-free at 4 months, analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00552149. Findings Between Oct 10, 2007, and Dec 18, 2009, 76 patients were assigned to chemotherapy plus cetuximab and 74 to chemotherapy alone. 48 (63%; 95% CI 52–74) patients assigned to chemotherapy plus cetuximab and 40 (54%; 43–65) assigned to chemotherapy alone were progression-free at 4 months. Median progression-free survival was 6·1 months (95% CI 5·1–7·6) in the chemotherapy plus cetuximab group and 5·5 months (3·7–6·6) in the chemotherapy alone group. Median overall survival was 11·0 months (9·1–13·7) in the chemotherapy plus cetuximab group and 12·4 months (8·6–16·0) in the chemotherapy alone group. The most common grade 3–4 adverse events were peripheral neuropathy (in 18 [24%] of 76 patients who received chemotherapy plus cetuximab vs ten [15%] of 68 who received chemotherapy alone), neutropenia (17 [22%] vs 11 [16%]), and increased aminotransferase concentrations (17 [22%] vs ten [15%]). 70 serious adverse events were reported in 39 (51%) of 76 patients who received chemotherapy plus cetuximab (34 events in 19 [25%] patients were treatment-related), whereas 41 serious adverse events were reported in 25 (35%) of 71 patients who received chemotherapy alone (20 events in 12 [17%] patients were treatment-related). One patient died of atypical pneumonia related to treatment in the chemotherapy alone group. Interpretation The addition of cetuximab to gemcitabine and oxaliplatin did not seem to enhance the activity of chemotherapy in patients with advanced biliary cancer, although it was well tolerated. Gemcitabine and platinum-based combination should remain the standard treatment option. Funding Institut National du Cancer, Merck Serono.

    ABSTRACT: BACKGROUND Until 2004, we treated peritoneal carcinomatosis with cytoreductive surgery accompanied by perioperative systemic chemotherapy. From October 2004, we decided to initiate a hyperthermic intraperitoneal chemotherapy (HIPEC) program for this condition. OBJECTIVE To determine the effect of HIPEC on postoperative outcomes at a single institution performing a high volume of cancer operations. METHOD Sixty consecutive patients underwent cytoreductive surgery plus HIPEC (oxaliplatin; 460 mg/m2 in 2 L/m2) from October 1, 2004, through December 31, 2010. Usual perioperative factors were studied for 3 groups of patients who underwent HIPEC: 0 to 20 HIPEC procedures (period 1), 21 to 40 HIPEC procedures (period 2), and 41 to 60 HIPEC procedures (period 3). RESULTS The mean peritoneal carcinomatosis index was 9.6, the mean duration of surgery was 410.7 minutes, and the mean blood loss was 450.2 mL/L. Mortality and morbidity were 0% and 33%, respectively. Grade III/IV morbidity (P = .02), transfusion (P < .01), and reintervention rate (P = .04) significantly decreased during the 3 periods. No difference was seen between the 3 periods with regard to mean peritoneal carcinomatosis index, operative duration, blood loss, mortality, overall morbidity, length of hospital stay, and readmission. The overall 1-, 3-, and 5-year survival rates of 26 patients with peritoneal carcinomatosis originating from colorectal cancer were 100%, 51%, and 37%, respectively. The overall median survival was 39 months. CONCLUSIONS We observed a significant reduction of grade III/IV morbidity, perioperative transfusion, and reintervention rate after 20 procedures. The introduction of the HIPEC program was successful because of the surgical team's prior experience in cytoreductive and cancer operations.

    ABSTRACT: Skin toxicity in patients receiving cetuximab has been associated positively with clinical outcome in several tumor types. This study investigated the effect of cetuximab dose escalation in patients with irinotecan-refractory metastatic colorectal cancer who had developed no or mild skin reactions after 21 days of treatment at the standard dose. This article reports clinical and pharmacokinetic (PK) data. After 21 days of standard-dose cetuximab (400 mg/m(2) initial dose, then 250 mg/m(2) per week) plus irinotecan, patients with ≤ grade 1 skin reactions were randomly assigned to standard-dose (group A) or dose-escalated (to 500 mg/m(2) per week; group B) cetuximab. Patients with ≥ grade 2 skin reactions continued on standard-dose cetuximab plus irinotecan (group C). The intent-to-treat population comprised 157 patients. PK profiles reflected the dose increase and were predictable across the dose range investigated. Weekly cetuximab doses of up to 500 mg/m(2) were well tolerated, and grade 3 and 4 adverse events were generally comparable between treatment groups. Dose escalation (n = 44) was associated with an increase in skin reactions ≥ grade 2 compared with standard (n = 45) dosing (59% v 38%, respectively). Dose escalation, compared with standard dosing, showed some evidence for improved response rate (30% v 16%, respectively) and disease control rate (70% v 58%, respectively) but no indication of benefit in relation to overall survival. In an exploratory analysis, dose escalation seemed to increase response rate compared with standard dosing in patients with KRAS wild-type but not KRAS mutant tumors. Cetuximab serum concentrations increased predictably with dose. Higher dose levels were well tolerated. The possible indication for improved efficacy in the dose-escalation group warrants further investigation.

    ABSTRACT: Context and objective  Biobanks have become strategic resources for biomedical and genetic research. The aim of the present empirical qualitative study was to investigate how patients with cancer perceive and experience the process of donation to biobanks, focussing on the subjective meanings associated with their decisions when they are asked in a routine context to agree to their own biological specimens being used for research projects. Design  A qualitative study, using semi-structured interviews to explore in depth the reasons why patients with cancer agree to participating in biobanking. Participants  Nineteen patients (aged 28-82 years) being treated for colorectal cancer or leukaemia at a French cancer centre participated in this study. Results  Contributing to biobanks was experienced here as a rewarding and empowering individual experience because of the psychological issues involved, such as feelings of hope associated with research, because it makes the relationship with researchers and clinicians less asymmetrical, revalorization of otherwise 'wasted' tissue, and also as an act of solidarity and reciprocity, which makes patients part of a community. Discussion and conclusion  Patients seem to regard contributing to biobanks as an act of benevolence, which they are motivated to perform because of societal welfare considerations as well as the hope of subjective benefits. Knowledge about the patients' perspective and of the psychological rewards associated with tumour donation should be taken into account by physicians and caregivers discussing this topic with their patients.

    ABSTRACT: Two-stage hepatectomy uses compensatory liver regeneration after a first noncurative hepatectomy to enable a second curative resection in patients with bilobar colorectal liver metastasis (CLM). To determine the predictive factors of failure of two-stage hepatectomy. Between 2000 and 2010, 48 patients with irresectable CLM were eligible for two-stage hepatectomy. The planned strategy was a) cleaning of the left hepatic lobe (first hepatectomy), b) right portal vein embolisation and c) right hepatectomy (second hepatectomy). Six patients had occult CLM (n = 5) or extra-hepatic disease (n = 1), which was discovered during the first hepatectomy. Thus, 42 patients completed the first hepatectomy and underwent portal vein embolisation in order to receive the second hepatectomy. Eight patients did not undergo a second hepatectomy due to disease progression. Upon univariate analysis, two factors were identified that precluded patients from having the second hepatectomy: the combined resection of a primary tumour during the first hepatectomy (p = 0.01) and administration of chemotherapy between the two hepatectomies (p = 0.03). An independent association with impairment to perform the two-stage strategy was demonstrated by multivariate analysis for only the combined resection of the primary colorectal cancer during the first hepatectomy (p = 0.04). Due to the small number of patients and the absence of equivalent conclusions in other studies, we cannot recommend performance of an isolated colorectal resection prior to chemotherapy. However, resection of an asymptomatic primary tumour before chemotherapy should not be considered as an outdated procedure.

    ABSTRACT: This study assesses the impact of preoperative chemoradiation on recurrence, surgical morbidity, histopathological data and survival in resectable adenocarcinoma of the pancreatic head. We carried out a retrospective study with an intention-to-treat analysis. From 1997 to 2006, 173 patients with resectable pancreas head carcinoma were treated in two reference centres in France using different treatment strategies. Sixty-seven of 85 (79%) patients in the surgery-first (SF) group and 38 of 88 (43%) patients in the chemoradiation (CR) group underwent surgical resection (P < 0.001). Overall morbidity was 40% (15/38) in the CR group and 43% (29/67) in the SF group (P= 0.837). In the CR group, median tumour size was smaller (1.5 cm vs. 3.0 cm; P < 0.001) and fewer patients were node-positive (29% vs. 64%; P= 0.001) than in the SF group. There was less perineural (43% vs. 93%; P < 0.001), lymphatic and vascular (21% vs. 92%; P < 0.001) invasion in the CR group than in the SF group. In both groups, 89% of patients had recurrence (31/35 in the CR group and 57/64 in the SF group; P= 1.000), predominantly involving metastasis and carcinomatosis in the CR group (30/31 vs. 35/57; P < 0.001) and locoregional recurrence in the SF group (24/57 vs. 3/31; P= 0.002). Median survival for all patients and for resected patients in the CR and SF groups was, respectively, 15 months vs. 17 months, and 21 months vs. 18 months (P= non-significant). Preoperative chemoradiation allows for good local control of the disease but does not increase survival, mainly for reasons of metastatic spread. Other options should be developed to improve both local and distant control of the disease.

    ABSTRACT: Triplet chemotherapy has demonstrated manageable toxicities and a favorable response rate. The addition of cetuximab to chemotherapy can increase treatment efficacy. We evaluated the efficacy and safety of cetuximab plus 5-fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX), the ERBIRINOX regimen, as first-line treatment in patients with unresectable metastatic colorectal cancer (mCRC). In a phase II study, treatment consisted of weekly cetuximab plus biweekly. Treatment was continued for a maximum of 12 cycles and tumor response was evaluated every four cycles. The primary efficacy criterion was the complete response (CR) rate. From April 2006 to April 2008, 42 patients were enrolled. The median age was 60 years (range, 32-76 years). The median duration of treatment was 5.2 months (range, 0.7-8.5 months), and a median of nine cycles was given per patient (range, 1-12 cycles). Five patients (11.9%) showed a CR, with a median duration of 23.1 months (95% confidence interval [CI], 10.8-39.7 months). The objective response rate was 80.9% (95% CI, 65.9%-91.4%). The median overall and progression-free survival times were 24.7 months (95% CI, 22.6 months to not reached) and 9.5 months (95% CI, 7.6-10.4 months), respectively. The most frequent grade 3-4 adverse events were diarrhea (52%), neutropenia (38%), and asthenia (32%). The ERBIRINOX regimen appears to be effective and feasible in first-line treatment of mCRC patients. These promising results led us to initiate a multicenter, randomized, phase II trial ([Research Partnership for Digestive Oncology] PRODIGE 14) in patients with potentially resectable mCRC.

    ABSTRACT: To explore possible improvement in the treatment of locally advanced pancreatic carcinoma (LAPC) we performed a randomized, non-comparative phase II study evaluating docetaxel - plus either daily continuous 5 FU or weekly cisplatin concurrent to radiotherapy. We report here the results of the docetaxel plus 5 FU regimen stopped according to the interim analysis. The docetaxel plus cisplatin arm was continued. Forty (40) chemotherapy-naive patients with unresectable LAPC were randomly assigned (1:1) to either continuous fluorouracil (5-FU) 200 mg/m(2)/day (protracted IV) and docetaxel (DCT) 20 mg/m(2)/week or DCT 20 mg/m2 and cisplatin (CDDP) 20 mg/m(2), plus concurrent radiotherapy for a period of 6 weeks. The radiation dose to the primary tumor was 54 Gy in 30 fractions. The trial's primary endpoint was the 6-month crude non-progression rate (NPR). Secondary endpoints were tolerance, objective response rate, and overall survival. Accrual was to be stopped if at 6 months more than 13 disease progressions were observed in 20 patients. Eighteen (18) progressions occurred at 6 months in the 5-FU-DCT arm. Six-month NPR was 10% (95%CI: 0-23). Six and 12-month survivals were 85% (95%CI: 64-95) and 40% (95%CI: 22-61); median overall survival was 10.1 months. Median progression-free survival was 4.3 months. We report the case of one patient who was amenable to surgery and has been in complete response (CR) for 5.5 years. Toxicities grade ≥ 3 were reported in 75% of patients; no treatment-related death occurred. Severe toxicities were mainly vomiting (35%), abdominal pain (10%) and fatigue (10%). Combination of 5-FU, docetaxel and radiotherapy has inadequate efficacy in the treatment of LAPC despite good tolerance for the 5-FU-DCT regimen. ClinicalTrials.gov: NCT00112697.

    ABSTRACT: This study retrospectively describes the outcome of a series of 38 patients (pts) with T4 anal carcinoma exclusively treated by radio and chemotherapy. From 1992 to 2007, 38 pts with UST4-N0-2-M0 anal carcinoma were treated with exclusive radiotherapy and chemotherapy. All patients received external beam radiotherapy (EBRT) (median dose 45 Gy) with a concomitant chemotherapy (5-fluorouracil-cisplatin). Eleven patients received neo-adjuvant chemotherapy (5-fluorouracil-cisplatin). After 2-8 weeks, a 15-20 Gy boost was delivered either with EBRT (20 pts) or interstitial (192)Ir brachytherapy (18 pts). Mean follow-up was 66 months. After chemoradiation therapy (CRT), 13 pts (34%) had a complete response, 23 pts (60%) a response >50% (2 pts were not evaluated). The 5-year-disease-free survival was 79.2 ± 6.5%, and the 5-year overall survival was 83.9 ± 6%. Eight patients developed tumor progression (mean delay 8.8 months), six of them requiring a salvage surgery with definitive colostomy for local relapse. Late severe complication requiring colostomy was observed in 2 pts. The 5-year-colostomy-free survival was 78 ± 6.9%. Patients who received primary chemotherapy had a statistically significant better 5-year colostomy-free survival (100% vs. 38 ± 16.4%, P = 0.0006). T4 anal carcinoma can be treated with a curative intent using a sphincter-sparing approach of CRT, and neo-adjuvant chemotherapy should be considered prior to radiotherapy.

    ABSTRACT: Pancreatic adenocarcinoma is one of the most aggressive human cancers. It displays many different chromosomal abnormalities and mutations. By using 244 K high-resolution array-comparative genomic hybridization (aCGH) we studied the genome alterations of 39 fine-needle aspirations from pancreatic adenocarcinoma and eight human adenocarcinoma pancreatic cell lines. Using both visual inspection and GISTIC analysis, recurrent losses were observed on 1p, 3p, 4p, 6, 8p, 9, 10, 11q, 15q, 17, 18, 19p, 20p, 21, and 22 and comprised several known or suspected tumor suppressor genes such as ARHGEF10, ARID1A, CDKN2A/B, FHIT, PTEN, RB1, RUNX1-3, SMAD4, STK11/LKB1, TP53, and TUSC3. Heterozygous deletion of the 1p35-p36 chromosomal region was identified in one-third of the tumors and three of the cell lines. This region, commonly deleted in human cancers, contains several tumor suppressor genes including ARID1A and RUNX3. We identified frequent genetic gains on chromosome arms 1q, 3q, 5p, 6p, 7q, 8q, 12q, 15q, 18q, 19q, and 20q. Amplifications were observed in 16 tumors. AKT2, CCND3, CDK4, FOXA2, GATA6, MDM2, MYC, and SMURF1 genes were gained or amplified. The most obvious amplification was located at 18q11.2 and targeted the GATA6 gene, which plays a predominant role in the initial specification of the pancreas and in pancreatic cell type differentiation. In conclusion, we have identified novel biomarkers and potential therapeutic targets in pancreatic adenocarcinoma.

    ABSTRACT: Neoadjuvant chemoradiation followed by surgery is the standard of care for locally advanced rectal cancer. The aim of this study was to correlate tumour response to survival and to identify predictive factors for tumour response after chemoradiation. From 1998 to 2008, 168 patients with histologically-proven locally advanced adenocarcinoma treated by preoperative chemoradiation before total mesorectal excision were retrospectively studied. They received a radiation dose of 45 Gy with a concomitant 5-fluoro-uracil-based chemotherapy. Analysis of tumour response was based on the lowering of T stage between pre-treatment endorectal ultrasound and pathologic specimens. Overall and progression-free survival was correlated with tumour response. Tumour response was analysed with predictive factors. The median follow-up was 34 months. Five-year disease-free survival and overall survival were respectively of 44.4% and 74.5% in the whole population, 83.4% and 83.4% in patients with pathological complete response, 38.6% and 71.9% in patients with tumour downstaging, 29.1% and 58.9% in patients with absence of response. A pre-treatment concentration of carcinoembryonnic antigen below 5 ng/mL was significantly associated with tumour downstaging and significantly independently associated with pathologic complete tumour response (P = 0.019). Downstaging and complete response after chemoradiation improved progression-free survival and overall survival of locally advanced rectal adenocarcinoma. In multivariate analysis, a pre-treatment concentration of carcinoembryonnic antigen below 5 ng/mL was associated with complete tumour response, hence with tumour downstaging.

    ABSTRACT: Objectives: This study investigated the effect of capecitabine-oxaliplatin (XELOX) on functional independence in patients aged >= 70 years with histologically proven metastatic colorectal cancer (mCRC). Materials and methods: Patients received capecitabine 750 mg/m(2) bid d1-14+oxaliplatin 90 mg/m(2) d1, every 3 weeks; doses were increased to 1000 and 120 mg/m(2,) respectively, in the absence of significant toxicity. The primary endpoint was stabilization/improvement of Katz Activities of Daily Living (ADL) scale. Results: Sixty patients were enrolled. ADL was stabilized/improved in 36/40 patients (90%) after 3 cycle, and in 25/27 patients (93%) after 6 cycles. Capecitabine and oxaliplatin doses were increased in 31% of patients. The objective response rate was 37% (1 complete and 21 68%, grade 3/4 in 2%), and grade 3/4 anemia (7%). Conclusion: This study demonstrates the feasibility of XELOX in elderly mCRC patients, with no impairment of independence among patients who remained on therapy.

    ABSTRACT: Cancer patients were questioned about the consent process in a context in which they were routinely requested to donate tumor samples to research. After in-depth interviews of 19 patients, a 12-page questionnaire was designed and mailed to 745 patients who had been recently treated for colorectal cancer, breast cancer, or a hematological malignancy at a French Regional Cancer Center at which an opt-in biobanking system has existed since 2002. The response rate was 77.0% (N = 574). Among responding patients, 349 (60.8%) of the 574 were in favor of a formal and signed consent. Concordance was low (kappa = 0.23) between the number of patients who declared in the survey that they had given consent (213 of 574 [37.1%]) vs the number for whom registered consent had been recorded (267 of 574 [46.5%]). Only 2 (0.3%) of the 574 patients stated that they had signed a refusal, and only 88 (41.3%) of the 213 patients who remembered giving consent understood that their consent for biobanking also covered authorization to use their clinical data. We conclude that the opt-in consent procedure is positively perceived by most patients but should be improved for a better understanding and possibly an even better adherence to the consent process.
