Neoadjuvant chemotherapy with FOLFIRINOX and preoperative chemoradiotherapy for patients with locally advanced rectal cancer (UNICANCER-PRODIGE 23): a multicentre, randomised, open-label, phase 3 trial.

BACKGROUND: Treatment of locally advanced rectal cancer with chemoradiotherapy, surgery, and adjuvant chemotherapy controls local disease, but distant metastases remain common. We aimed to assess whether administering neoadjuvant chemotherapy before preoperative chemoradiotherapy could reduce the risk of distant recurrences. METHODS: We did a phase 3, open-label, multicentre, randomised trial at 35 hospitals in France. Eligible patients were adults aged 18-75 years and had newly diagnosed, biopsy-proven, rectal adenocarcinoma staged cT3 or cT4 M0, with a WHO performance status of 0-1. Patients were randomly assigned (1:1) to either the neoadjuvant chemotherapy group or standard-of-care group, using an independent web-based system by minimisation method stratified by centre, extramural extension of the tumour into perirectal fat according to MRI, tumour location, and stage. Investigators and participants were not masked to treatment allocation. The neoadjuvant chemotherapy group received neoadjuvant chemotherapy with FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2 intravenously every 14 days for 6 cycles), chemoradiotherapy (50 Gy during 5 weeks and 800 mg/m2 concurrent oral capecitabine twice daily for 5 days per week), total mesorectal excision, and adjuvant chemotherapy (3 months of modified FOLFOX6 [intravenous oxaliplatin 85 mg/m2 and leucovorin 400 mg/m2, followed by intravenous 400 mg/m2 fluorouracil bolus and then continuous infusion at a dose of 2400 mg/m2 over 46 h every 14 days for six cycles] or capecitabine [1250 mg/m2 orally twice daily on days 1-14 every 21 days]). The standard-of-care group received chemoradiotherapy, total mesorectal excision, and adjuvant chemotherapy (for 6 months). The primary endpoint was disease-free survival assessed in the intention-to-treat population at 3 years. Safety analyses were done on treated patients. This trial was registered with EudraCT (2011-004406-25) and ClinicalTrials.gov (NCT01804790) and is now complete. FINDINGS: Between June 5, 2012, and June 26, 2017, 461 patients were randomly assigned to either the neoadjuvant chemotherapy group (n=231) or the standard-of-care group (n=230). At a median follow-up of 46·5 months (IQR 35·4-61·6), 3-year disease-free survival rates were 76% (95% CI 69-81) in the neoadjuvant chemotherapy group and 69% (62-74) in the standard-of-care group (stratified hazard ratio 0·69, 95% CI 0·49-0·97; p=0·034). During neoadjuvant chemotherapy, the most common grade 3-4 adverse events were neutropenia (38 [17%] of 225 patients) and diarrhoea (25 [11%] of 226). During chemoradiotherapy, the most common grade 3-4 adverse event was lymphopenia (59 [28%] of 212 in the neoadjuvant chemotherapy group vs 67 [30%] of 226 patients in the standard-of-care group). During adjuvant chemotherapy, the most common grade 3-4 adverse events were lymphopenia (18 [11%] of 161 in the neoadjuvant chemotherapy group vs 42 [27%] of 155 in the standard-of-care group), neutropenia (nine [6%] of 161 vs 28 [18%] of 155), and peripheral sensory neuropathy (19 [12%] of 162 vs 32 [21%] of 155). Serious adverse events occurred in 63 (27%) of 231 participants in the neoadjuvant chemotherapy group and 50 (22%) of 230 patients in the standard-of-care group (p=0·167), during the whole treatment period. During adjuvant therapy, serious adverse events occurred in 18 (11%) of 163 participants in the neoadjuvant chemotherapy group and 36 (23%) of 158 patients in the standard-of-care group (p=0·0049). Treatment-related deaths occurred in one (<1%) of 226 patients in the neoadjuvant chemotherapy group (sudden death) and two (1%) of 227 patients in the standard-of-care group (one sudden death and one myocardial infarction). INTERPRETATION: Intensification of chemotherapy using FOLFIRINOX before preoperative chemoradiotherapy significantly improved outcomes compared with preoperative chemoradiotherapy in patients with cT3 or cT4 M0 rectal cancer. The significantly improved disease-free survival in the neoadjuvant chemotherapy group and the decreased neurotoxicity indicates that the perioperative approach is more efficient and better tolerated than adjuvant chemotherapy. Therefore, the PRODIGE 23 results might change clinical practice. FUNDING: Institut National du Cancer, Ligue Nationale Contre le Cancer, and R&D Unicancer.

Artificial intelligence-guided tissue analysis combined with immune infiltrate assessment predicts stage III colon cancer outcomes in PETACC08 study.

OBJECTIVE: Diagnostic tests, such as Immunoscore, predict prognosis in patients with colon cancer. However, additional prognostic markers could be detected on pathological slides using artificial intelligence tools. DESIGN: We have developed a software to detect colon tumour, healthy mucosa, stroma and immune cells on CD3 and CD8 stained slides. The lymphocyte density and surface area were quantified automatically in the tumour core (TC) and invasive margin (IM). Using a LASSO algorithm, DGMate (DiGital tuMor pArameTErs), we detected digital parameters within the tumour cells related to patient outcomes. RESULTS: Within the dataset of 1018 patients, we observed that a poorer relapse-free survival (RFS) was associated with high IM stromal area (HR 5.65; 95% CI 2.34 to 13.67; p<0.0001) and high DGMate (HR 2.72; 95% CI 1.92 to 3.85; p<0.001). Higher CD3+ TC, CD3+ IM and CD8+ TC densities were significantly associated with a longer RFS. Analysis of variance showed that CD3+ TC yielded a similar prognostic value to the classical CD3/CD8 Immunoscore (p=0.44). A combination of the IM stromal area, DGMate and CD3, designated 'DGMuneS', outperformed Immunoscore when used in estimating patients' prognosis (C-index=0.601 vs 0.578, p=0.04) and was independently associated with patient outcomes following Cox multivariate analysis. A predictive nomogram based on DGMuneS and clinical variables identified a group of patients with less than 10% relapse risk and another group with a 50% relapse risk. CONCLUSION: These findings suggest that artificial intelligence can potentially improve patient care by assisting pathologists in better defining stage III colon cancer patients' prognosis.

First-Line Chemotherapy for Metastatic Esophageal Squamous Cell Carcinoma: Clinico-Biological Predictors of Disease Control.

OBJECTIVE: This study aimed to identify predictors of tumor control (TC) in metastatic esophageal squamous cell carcinoma patients receiving first-line chemotherapy. METHODS: A development cohort of 68 patients from a prospective multicenter trial (NCT01248299) was used to identify predictors of TC at first radiological tumor assessment and to generate a predictive score for TC. That score was applied in an independent retrospective single-center validation cohort of 60 consecutive patients. RESULTS: Multivariate analysis identified three predictors of TC: body mass index ≥18.5 (OR 4.5, 95% CI 0.91-22.5), absence of bone metastasis (OR 4.6, 95% CI 0.91-23.2) and albumin ≥35 g/l (OR 3.5, 95% CI 1.0-12.1). Based on the presence or absence of these three independent prognosticators, we built a predictive model using a score from 0 to 3. In the development cohort, the TC rates were 14.3 and 78.0% and in the validation cohort 12.5 and 44.2%, for scores of 0-1 and 2-3, respectively. With negative predictive values of 85 and 88% in the development and validation cohorts, respectively, we were able to identify patients with a very low probability of TC. CONCLUSION: We have developed and validated a score that can be easily determined at the bedside to predict TC in metastatic esophageal squamous cell carcinoma patients.

Survival, safety, and prognostic factors for outcome with Regorafenib in patients with metastatic colorectal cancer refractory to standard therapies: results from a multicenter study (REBECCA) nested within a compassionate use program.

BACKGROUND: Randomized trials have shown a survival benefit for regorafenib over placebo in patients with metastatic colorectal cancer (mCRC) that progressed after standard therapies. We evaluated survival and safety outcomes in patients treated with regorafenib in a real-life setting. METHODS: REBECCA is a cohort study nested within a compassionate use program designed to evaluate survival, safety, and potential prognostic factors for outcome associated with regorafenib in patients with mCRC refractory to standard therapies. Treatment effects according to various patient and tumour characteristics were evaluated using univariate and multivariate Cox proportional hazards regression models. RESULTS: Of 1178 patients in the compassionate use program, 654 were in the full analysis set. Median follow-up was 16.5 months. Median survival was 5.6 months. The 12-month survival rate was 22 %. Survival was independently and unfavourably affected by the following variables: poor performance status, short time from initial diagnosis of metastases to the start of regorafenib, low initial regorafenib dose, >3 metastatic sites, presence of liver metastases, and KRAS mutations. We identified prognostic groups of patients with low, intermediate, and high risk of death, with a median survival of 9.2, 5.2, and 2.5 months, respectively. Five-hundred-twenty-four patients (80 %) experienced at least one regorafenib-related adverse event, most commonly, fatigue, hand-foot skin reaction, diarrhea, anorexia, arterial hypertension, and mucositis. CONCLUSION: The safety and efficacy profile of regorafenib in REBECCA are similar to those in randomized trials. Our prognostic model identified subgroups of mCRC patients who derived a minimal and maximum benefit from regorafenib. TRIAL REGISTRATION: Clinicaltrials.gov NCT02310477 .

Definitive chemoradiotherapy with FOLFOX versus fluorouracil and cisplatin in patients with oesophageal cancer (PRODIGE5/ACCORD17): final results of a randomised, phase 2/3 trial.

BACKGROUND: Definitive chemoradiotherapy is a curative treatment option for oesophageal carcinoma, especially in patients unsuitable for surgery. The PRODIGE5/ACCORD17 trial aimed to assess the efficacy and safety of the FOLFOX treatment regimen (fluorouracil plus leucovorin and oxaliplatin) versus fluorouracil and cisplatin as part of chemoradiotherapy in patients with localised oesophageal cancer. METHODS: We did a multicentre, randomised, open-label, parallel-group, phase 2/3 trial of patients aged 18 years or older enrolled from 24 centres in France between Oct 15, 2004, and Aug 25, 2011. Eligible participants had confirmed stage I-IVA oesophageal carcinoma (adenocarcinoma, squamous-cell, or adenosquamous), Eastern Cooperative Oncology Group (ECOG) status 0-2, sufficient caloric intake, adequate haematological, renal, and hepatic function, and had been selected to receive definitive chemoradiotherapy. Patients were randomly assigned (1:1) to receive either six cycles (three concomitant to radiotherapy) of oxaliplatin 85 mg/m(2), leucovorin 200 mg/m(2), bolus fluorouracil 400 mg/m(2), and infusional fluorouracil 1600 mg/m(2) (FOLFOX) over 46 h, or four cycles (two concomitant to radiotherapy) of fluorouracil 1000 mg/m(2) per day for 4 days and cisplatin 75 mg/m(2) on day 1. Both groups also received 50 Gy radiotherapy in 25 fractions (five fractions per week). Random allocation to treatment groups was done by a central computerised randomisation procedure by minimisation, stratified by centre, histology, weight loss, and ECOG status, and was achieved independently from the study investigators. The primary endpoint was progression-free survival. Data analysis was primarily done by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00861094. FINDINGS: 134 participants were randomly allocated to the FOLFOX group and 133 to the fluorouracil and cisplatin group (intention-to-treat population), and 131 patients in the FOLFOX group and 128 in the fluorouracil and cisplatin group actually received the study drugs (safety population). Median follow-up was 25·3 months (IQR 15·9-36·4). Median progression-free survival was 9·7 months (95% CI 8·1-14·5) in the FOLFOX group and 9·4 months (8·1-10·6) in the fluorouracil and cisplatin group (HR 0·93, 95% CI 0·70-1·24; p=0·64). One toxic death occurred in the FOLFOX group and six in the fluorouracil-cisplatin group (p=0·066). No significant differences were recorded in the rates of most frequent grade 3 or 4 adverse events between the treatment groups. Of all-grade adverse events that occurred in 5% or more of patients, paraesthesia (61 [47%] events in 131 patients in the FOLFOX group vs three [2%] in 128 patients in the cisplatin-fluorouracil group, p<0·0001), sensory neuropathy (24 [18%] vs one [1%], p<0·0001), increases in aspartate aminotransferase concentrations (14 [11%] vs two [2%], p=0·002), and increases in alanine aminotransferase concentrations (11 [8%] vs two [2%], p=0·012) were more common in the FOLFOX group, whereas serum creatinine increases (four [3%] vs 15 [12%], p=0·007), mucositis (35 [27%] vs 41 [32%], p=0·011), and alopecia (two [2%] vs 12 [9%], p=0·005) were more common in the fluorouracil and cisplatin group. INTERPRETATION: Although chemoradiotherapy with FOLFOX did not increase progression-free survival compared with chemoradiotherapy with fluorouracil and cisplatin, FOLFOX might be a more convenient option for patients with localised oesophageal cancer unsuitable for surgery.

Neoadjuvant chemotherapy with FOLFIRINOX and preoperative chemoradiotherapy for patients with locally advanced rectal cancer (UNICANCER PRODIGE 23): Health-related quality of life longitudinal analysis.

BACKGROUND: Results from the phase 3 PRODIGE 23 study showed that neoadjuvant chemotherapy (NAC) with mFOLFIRINOX and preoperative chemoradiotherapy improved disease-free survival compared with preoperative chemoradiotherapy in patients with locally advanced rectal cancer. We aimed to assess the health-related quality of life (HRQOL) outcomes from this study. PATIENTS AND METHODS: A total of 461 patients (231 versus 230 patients) from 35 French hospitals were randomly assigned to either NAC with FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, fluorouracil 2400 mg/m2 over 46 h intravenously every 2 weeks for 6 cycles) followed by preoperative chemoradiotherapy or chemoradiotherapy only. HRQOL was assessed at baseline, during treatments and at 2-year follow-up using the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR29 questionnaires. RESULTS: Compared to baseline, HRQOL scores during NAC were better for tumour symptoms but worse for global health status, functional domains, fatigue, nausea/vomiting and appetite loss. During follow-up, improved emotional functioning was observed, but deterioration of body image, increased urinary incontinence, and lower male sexual function were observed. Linear mixed model exhibited a treatment-by-time interaction effect for nausea/vomiting and insomnia symptoms showing a greater deterioration in the standard-of-care group. Only treatment arm and baseline physical functioning were independent significant favourable prognostic factors. CONCLUSION: NAC improved tumour-related symptoms and transitorily reduced most functional scores. Adding NAC before chemoradiotherapy and increased physical functioning at baseline were independent significant prognostic factors for longer disease-free survival.

Panitumumab in combination with chemoradiotherapy for the treatment of locally-advanced anal canal carcinoma: Results of the FFCD 0904 phase II trial.

BACKGROUND AND PURPOSE: Standard treatment of squamous cell carcinoma of the anus (SCCA)is 5-fluorouracil (5FU) and mitomycin C (MMC) based chemoradiotherapy (CRT). This phase II study (EudraCT: 2011-005436-26) assessed the tolerance and complete response (CR) rate at 8 weeks of panitumumab (Pmab) combined with MMC-5FU-based CRT. METHODS: Patients with locally advanced tumors without metastases (T2 > 3 cm, T3-T4, or N + whatever T stage) were treated with IMRT up to 65 Gy and concomitant CT according to the doses defined by a previous phase I study (MMC: 10 mg/m2; 5FU: 400 mg/m2; Pmab: 3 mg/kg). The expected CR rate was 80%. RESULTS: Forty-five patients (male: 9, female: 36; median age: 60.1 [41.5-81]) were enrolled in 15 French centers. The most common related grade 3-4 toxicities observed were digestive (51.1%), hematologic (lymphopenia: 73.4%; neutropenia: 11.1%), radiation dermatitis (13.3%), and asthenia (11.1%) with RT interruption in 14 patients. One patient died because of mesenteric ischemia during the CRT, possibly related to treatment. In ITT analysis, the CR rate at 8 weeks after CRT was 66.7% [90%CI: 53.4-78.2]. Median follow-up was 43.6 months [IC 95%: 38.61-47.01]. Overall survival, recurrence-free and colostomy-free survival at 3 years were 80% [95%CI: 65.1-89], 62.2% [IC95%: 46.5-74.6] and 68.8 % [IC95%: 53.1-80.2] respectively. CONCLUSION: Panitumumab in combination with CRT for locally advanced SCCA failed to meet the expected CR rate and exhibited a poor tolerance. Furthermore, late RFS, CFS, and OS did not suggest any outcome improvement to justify further clinical trials. CLINICALTRIALS: gov identifier: NCT01581840.

Preliminary tolerance analysis of adjuvant chemotherapy in older patients after resection of stage III colon cancer from the PRODIGE 34-FFCD randomized trial.

BACKGROUND: Colon adenocarcinoma mainly occurs in older patients. Oxaliplatin-based adjuvant chemotherapy improved disease-free survival after stage III colon cancer resection, but this improvement was not demonstrated in older patients. METHODS: The purpose of ADAGE-PRODIGE 34, randomized open phase III trial is to compare in patients over 70 years oxaliplatin plus fluoropyrimidine with fluoropyrimidine alone in fit patients (Group 1) and fluoropyrimidine with observation in frail patients (Group 2) after resection of stage III colon adenocarcinoma. We report a preliminary tolerance analysis on 50% of the first patients enrolled. RESULTS: The analysis was conducted on 491 patients (378 in Group 1 and 113 in Group 2). Patients in Group 2 were older and showed more frailty criteria than those in Group 1. Cumulative grade 3-5 toxicities were more frequent in patients treated with oxaliplatin in Group 1 or with fluoropyrimidine in Group 2 than in patients treated with fluoropyrimidine in Group 1. At least one course was deferred in more than half of the patients in all groups. Early treatment cessation was more frequent in Group 2. CONCLUSION: No safety concerns were raised for the continuation of accrual. The frailty criteria distribution suggests that the investigator's evaluation for group allocation was accurate.

Sequential versus combination chemotherapy for the treatment of advanced colorectal cancer (FFCD 2000-05): an open-label, randomised, phase 3 trial.

BACKGROUND: The optimum use of cytotoxic drugs for advanced colorectal cancer has not been defined. Our aim was to investigate whether combination treatment is better than the sequential administration of the same drugs in patients with advanced colorectal cancer. METHODS: In this open-label, randomised, phase 3 trial, we randomly assigned patients (1:1 ratio) with advanced, measurable, non-resectable colorectal cancer and WHO performance status 0-2 to receive either first-line treatment with bolus (400 mg/m(2)) and infusional (2400 mg/m(2)) fluorouracil plus leucovorin (400 mg/m(2)) (simplified LV5FU2 regimen), second-line LV5FU2 plus oxaliplatin (100 mg/m(2)) (FOLFOX6), and third-line LV5FU2 plus irinotecan (180 mg/m(2)) (FOLFIRI) or first-line FOLFOX6 and second-line FOLFIRI. Chemotherapy was administered every 2 weeks. Randomisation was done centrally using minimisation (minimisation factors were WHO performance status, previous adjuvant chemotherapy, number of disease sites, and centre). The primary endpoint was progression-free survival after two lines of treatment. Analyses were by intention-to-treat. This trial is registered at ClinicalTrials.gov, NCT00126256. FINDINGS: 205 patients were randomly assigned to the sequential group and 205 to the combination group. 161 (79%) patients in the sequential group and 161 (79%) in the combination group died during the study. Median progression-free survival after two lines was 10·5 months (95% CI 9·6-11·5) in the sequential group and 10·3 months (9·0-11·9) in the combination group (hazard ratio 0·95, 95% CI 0·77-1·16; p=0·61). All six deaths caused by toxic effects of treatment occurred in the combination group. During first-line chemotherapy, significantly fewer severe (grade 3-4) haematological adverse events (12 events in 203 patients in sequential group vs 83 events in 203 patients in combination group; p<0·0001) and non-haematological adverse events (26 events vs 186 events; p<0·0001) occurred in the sequential group than in the combination group. INTERPRETATION: Upfront combination chemotherapy is more toxic and is not more effective than the sequential use of the same cytotoxic drugs in patients with advanced, non-resectable colorectal cancer.

Renal function in patients receiving streptozocin for locally advanced or metastatic digestive neuroendocrine tumours: results of the Streptotox-FFCD 0906 study.

INTRODUCTION: Streptozocin can impair renal function. The purpose of this study was to evaluate the evolution of renal function in patients receiving this anti-mitotic for the treatment of locally advanced/metastatic digestive well differentiated neuroendocrine tumours. METHODS: A prospective and a retrospective cohort of patients with normal baseline renal function were analysed. The primary endpoint was the incidence of a decrease in the estimated glomerular filtration rate ≥ 25% during treatment. Secondary endpoints were the evaluation of glomerular filtration rate changes, the impact of combined nephrotoxic treatments, other toxicities, compliance, and the objective response rate. RESULTS: After screening 142 patients, 27 were included in the prospective and 84 in the retrospective cohort. A decrease in estimated glomerular filtration rate ≥ 25% was observed in 32 patients (30%): respectively four (15.4%) and 28 patients (34.1%) among respectively 26 and 82 patients with numerous measures (P = 0.0097). Altogether, 39 patients (35%) experienced grade 1-2 renal toxicity, while no grade 3-4 occurred in the prospective and 1 occurred in the retrospective cohort. Renal toxicity was more frequent in the retrospective cohort with a less careful follow up. As best responses, objective response was achieved in 27% of patients with pancreatic primary tumours, disease control in 78.9% of patients with pancreatic primary tumours, in 87% of those with small bowel tumours and in 72.7% of patients with other primary locations. CONCLUSIONS: Strongly recommended for pancreatic NET, streptozocin is associated with frequent mild renal toxicity but low occurrence of renal impairment in patients with baseline normal renal function and under adequate hydration.

MRI-Based Radiomics Input for Prediction of 2-Year Disease Recurrence in Anal Squamous Cell Carcinoma.

PURPOSE: Chemo-radiotherapy (CRT) is the standard treatment for non-metastatic anal squamous cell carcinomas (ASCC). Despite excellent results for T1-2 stages, relapses still occur in around 35% of locally advanced tumors. Recent strategies focus on treatment intensification, but could benefit from a better patient selection. Our goal was to assess the prognostic value of pre-therapeutic MRI radiomics on 2-year disease control (DC). METHODS: We retrospectively selected patients with non-metastatic ASCC treated at the CHU Bordeaux and in the French FFCD0904 multicentric trial. Radiomic features were extracted from T2-weighted pre-therapeutic MRI delineated sequences. After random division between training and testing sets on a 2:1 ratio, univariate and multivariate analysis were performed on the training cohort to select optimal features. The correlation with 2-year DC was assessed using logistic regression models, with AUC and accuracy as performance gauges, and the prediction of disease-free survival using Cox regression and Kaplan-Meier analysis. RESULTS: A total of 82 patients were randomized in the training (n = 54) and testing sets (n = 28). At 2 years, 24 patients (29%) presented relapse. In the training set, two clinical (tumor size and CRT length) and two radiomic features (FirstOrder_Entropy and GLCM_JointEnergy) were associated with disease control in univariate analysis and included in the model. The clinical model was outperformed by the mixed (clinical and radiomic) model in both the training (AUC 0.758 versus 0.825, accuracy of 75.9% versus 87%) and testing (AUC 0.714 versus 0.898, accuracy of 78.6% versus 85.7%) sets, which led to distinctive high and low risk of disease relapse groups (HR 8.60, p = 0.005). CONCLUSION: A mixed model with two clinical and two radiomic features was predictive of 2-year disease control after CRT and could contribute to identify high risk patients amenable to treatment intensification with view of personalized medicine.

Evaluation of Nurses' and Patients' Overall Satisfaction with New and Previous Formulations of Octreotide Long-acting Release (Sandostatin LAR®): A French Observational Study.

INTRODUCTION: The first long-acting release (LAR) formulation of octreotide was marketed in France in the late 1990s. An injectable formulation of Sandostatin LAR® (Novartis SAS) with a new diluent has been developed to facilitate its preparation and administration and to improve its use in practice. METHODS: We conducted an observational, cross-sectional and multicenter study in France whose main outcome was to compare nurses' satisfaction with the preparation and administration of both previous and new formulations of octreotide LAR. Secondary outcomes included assessment of patient satisfaction (quality of life and pain felt during the injection) and product tolerance. Data were collected at two time points (one for the first formulation group and one for the second formulation group) through paper questionnaires administered to physicians, patients and nurses including a visual analog scale (VAS) from 0 (unsatisfied) to 10 (very satisfied). RESULTS: Results showed that overall nurse satisfaction improved from 5.3 (95% CI 4.9-5.8) with the previous formulation to 7.5 (95% CI 7-7.9) with the new formulation (p < 0.0001). Regarding secondary outcomes, the simplicity of the injection increased (84% for the previous formulation and 94% for the new formulation) and the purge problem disappeared (36% for the previous formulation and 4% for the new formulation). CONCLUSION: The improvement due to the new formulation of Sandostatin LAR® was reported in terms of handling, ease of use and overall nurse satisfaction. The new formulation greatly reduced treatment administration problems associated with the previous formulation, while maintaining low injection site pain and an equivalent safety profile in both indications.

Baseline Splenic Volume as a Prognostic Biomarker of FOLFIRI Efficacy and a Surrogate Marker of MDSC Accumulation in Metastatic Colorectal Carcinoma.

BACKGROUND: Predictive biomarkers of response to chemotherapy plus antiangiogenic for metastatic colorectal cancer (mCRC) are lacking. The objective of this study was to test the prognostic role of splenomegaly on baseline CT scan. METHODS: This study is a sub-study of PRODIGE-9 study, which included 488 mCRC patients treated by 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) and bevacizumab in first line. The association between splenic volume, and PFS and OS was evaluated by univariate and multivariable Cox analyses. The relation between circulating monocytic Myeloid derived suppressor cells (mMDSC) and splenomegaly was also determined. RESULTS: Baseline splenic volume > 180 mL was associated with poor PFS (median PFS = 9.2 versus 11.1 months; log-rank p = 0.0125), but was not statistically associated with OS (median OS = 22.6 versus 28.5 months; log-rank p = 0.1643). The increase in splenic volume at 3 months had no impact on PFS (HR 0.928; log-rank p = 0.56) or on OS (HR 0.843; log-rank p = 0.21). Baseline splenic volume was positively correlated with the level of baseline circulating mMDSC (r = 0.48, p-value = 0.031). CONCLUSION: Baseline splenomegaly is a prognostic biomarker in patients with mCRC treated with FOLFIRI and bevacizumab, and a surrogate marker of MDSC accumulation.

Quality of life and cost of strategies of two chemotherapy lines in metastatic colorectal cancer: results of the FFCD 2000-05 trial.

Objectives: This study compared the cost and quality of life (QoL) of 407 advanced colorectal cancer patients, randomly assigned to receive LV5FU2 followed by FOLFOX6 (sequential strategy) or FOLFOX6 followed by FOLFIRI (combination strategy). Methods: Costs were compared from the French health insurance perspective, until the end of the second line of treatment. Consumed resources, collected during the trial, included medicines, hospitalizations, examinations, and transportation. Valuations were made using 2009 and 2016 tariffs. QoL was assessed using the QLQ-C30 questionnaire and clinically significant variations were searched. Results: In 2009, the mean cost per patient was significantly lower for the sequential strategy compared to the combination strategy (18,061€ and 23,119€, p = 0.001). In 2016, the difference was no longer significant (16,876€ and 18,090€, p = 0.41) because oxaliplatin and irinotecan became generics. The QoL analysis (292 patients) showed that there was significantly less improvement of global health status in the sequential strategy than in the combination strategy (29% and 42%; p = 0.02) during first-line therapy. No significant differences were observed for emotional functioning (p = 0.45) and physical functioning (p = 0.07) or during second-line therapy. Conclusion: The choice to treat patients with advanced colorectal cancer using one or the other strategy cannot be based on costs or QoL.

Overweight is associated to a better prognosis in metastatic colorectal cancer: A pooled analysis of FFCD trials.

BACKGROUND: Previous studies showed that high and low body mass index (BMI) was associated with worse prognosis in early-stage colorectal cancer (CRC), and low BMI was associated with worse prognosis in metastatic CRC (mCRC). We aimed to assess efficacy outcomes according to BMI. PATIENTS AND METHODS: A pooled analysis of individual data from 2085 patients enrolled in eight FFCD first-line mCRC trials from 1991 to 2013 was performed. Comparisons were made according to the BMI cut-off: Obese (BMI ≥30), overweight patients (BMI ≥ 25), normal BMI patients (BMI: 18.5-24) and thin patients (BMI <18.5). Interaction tests were performed between BMI effect and sex, age and the addition of antiangiogenics to chemotherapy. RESULTS: The rate of BMI ≥25 patients was 41.5%, ranging from 37.6% (1991-1999 period) to 41.5% (2000-2006 period) and 44.8% (2007-2013 period). Comparison of overweight patients versus normal BMI range patients revealed a significant improvement of median overall survival (OS) (18.5 versus 16.3 months, HR = 0.88 [0.80-0.98] p = 0.02) and objective response rate (ORR) (42% versus 36% OR = 1.23 [1.01-1.50] p = 0.04) but a comparable median progression-free survival (PFS) (7.8 versus 7.2 months, HR = 0.96 [0.87-1.05] p = 0.35). Subgroup analyses revealed that overweight was significantly associated with better OS in men. OS and PFS were significantly shorter in thin patients. CONCLUSION: Overweight patients had a prolonged OS compared with normal weight patients with mCRC. The association of overweight with better OS was only observed in men. The pejorative prognosis of BMI <18.5 was confirmed.

Docetaxel plus gemcitabine or docetaxel plus cisplatin in advanced pancreatic carcinoma: randomized phase II study 40984 of the European Organisation for Research and Treatment of Cancer Gastrointestinal Group.

PURPOSE: To define the efficacy and toxicity of docetaxel plus gemcitabine or docetaxel plus cisplatin for advanced pancreatic carcinoma. PATIENTS AND METHODS: Chemotherapy-naive patients with measurable disease and WHO performance status less than 2 were randomly assigned to receive 21-day cycles of gemcitabine 800 mg/m2 on days 1 and 8 plus docetaxel 85 mg/m2 on day 8 (arm A) or docetaxel 75 mg/m2 on day 1 plus cisplatin 75 mg/m2 on day 1 (arm B). Primary end points were tumor response and rate of febrile neutropenia grade. RESULTS: Of 96 randomly assigned patients (49 patients in arm A and 47 patients in arm B), 70 patients were analyzed for response (36 in arm A and 34 in arm B) and 89 patients were analyzed for safety (45 in arm A and 44 in arm B). Confirmed responses were observed in 19.4% (95% CI, 8.2% to 36.0%) of patients in arm A and 23.5% (95% CI, 10.7% to 41.2%) in arm B. In arm A, the median progression-free survival (PFS) was 3.9 months (95% CI, 3.0 to 4.7 months), median survival was 7.4 months (95% CI, 5.6 to 11.0 months), and 1-year survival was 30%. In arm B, the median PFS was 2.8 months (95% CI, 2.6 to 4.6 months), median survival was 7.1 months (95% CI, 4.8 to 8.7 months), and 1-year survival was 16%. Febrile neutropenia occurred in 9% and 16% of patients in arms A and B, respectively. CONCLUSION: Both regimens are well tolerated and show activity in advanced pancreatic carcinoma. The safety profile and survival analyses favor docetaxel plus gemcitabine for further evaluation.

Oxaliplatin combined with 5-FU in second line treatment of advanced pancreatic adenocarcinoma. Results of a phase II trial.

BACKGROUND: The efficacy and benefit of second-line chemotherapy in advanced pancreatic adenocarcinoma has never been demonstrated although it is regularly used. PATIENTS AND METHODS: A randomized phase II study evaluating oxaliplatin alone (OXA), infusional 5-fluorouracil alone (5-FU) and an oxaliplatin/infusional 5-FU combination (OXFU) in untreated advanced pancreatic adenocarcinoma has been conducted. In this trial, a second-line treatment with the OXFU regimen (OXA 130 mg/m2 2-h intravenous (i.v.) infusion combined with 5-FU (1000 mg/m2/day, continuous i.v., days 1-4), every 3 weeks) was offered to patients progressing after single agent treatment. RESULTS: Eighteen out of 32 patients (12 males, median age 57 years) treated in the single agent arms received the OXFU combination in second-line treatment. WHO performance status was at least 2 in 61% of the patients. There was no objective response and 3 patients (17%) had a disease stabilisation. Median time to progression from the start of second-line treatment was 0.9 months. Median overall survival was 4.9 months from the start of front-line therapy and 1.3 months from the start of second-line therapy. CONCLUSION: The results of this trial bring arguments to support a modest value of second-line chemotherapy for advanced pancreatic adenocarcinoma.

Randomized multicenter phase II trial of a biweekly regimen of fluorouracil and leucovorin (LV5FU2), LV5FU2 plus cisplatin, or LV5FU2 plus irinotecan in patients with previously untreated metastatic gastric cancer: a Federation Francophone de Cancerologie Digestive Group Study--FFCD 9803.

PURPOSE: To determine the efficacy and safety of a biweekly regimen of leucovorin (LV) plus fluorouracil (FU) alone or in combination with cisplatin or irinotecan in patients with previously untreated metastatic gastric adenocarcinoma and to select the best arm for a phase III study. PATIENTS AND METHODS: One hundred thirty-six patients (two were ineligible) were enrolled onto the randomized multicenter phase II trial. Patients received LV 200 mg/m(2) (2-hour infusion) followed by FU 400 mg/m(2) (bolus) and FU 600 mg/m(2) (22-hour continuous infusion) on days 1 and 2 every 14 days (LV5FU2; arm A), LV5FU2 plus cisplatin 50 mg/m(2) (1-hour infusion) on day 1 or 2 (arm B), or LV5FU2 plus irinotecan 180 mg/m(2) (2-hour infusion) on day 1 (arm C). RESULTS: The overall response rates, which were confirmed by an independent expert panel, were 13% (95% CI, 3.4% to 23.3%), 27% (95% CI, 14.1% to 40.4%), and 40% (95% CI, 25.7% to 54.3%) for arms A, B, and C, respectively. Median progression-free survival and overall survival times were 3.2 months (95% CI, 1.8 to 4.6 months) and 6.8 months (95% CI, 2.6 to 11.1 months) with LV5FU2, respectively; 4.9 months (95% CI, 3.5 to 6.3 months) and 9.5 months (95% CI, 6.9 to 12.2 months) with LV5FU2-cisplatin, respectively; and 6.9 months (95% CI, 5.5 to 8.3 months) and 11.3 months (95% CI, 9.3 to 13.3 months) with LV5FU2-irinotecan, respectively. CONCLUSION: Of the three regimens tested, the combination of LV5FU2-irinotecan is the most promising and will be assessed in a phase III trial.

Longitudinal quality of life study in patients with metastatic gastric cancer. Analysis modalities and clinical applicability of QoL in randomized phase II trial in a digestive oncology.

OBJECTIVES: The aim of this study was to compare the longitudinal quality of life (QoL) between LV5FU2-irinotecan and LV5FU2 alone or LV5FU2-cisplatin in a randomized Phase II trial in patients with metastatic gastric adenocarcinoma. METHODS: Among 134 eligible patients, QLQ-C30 scores were collected and described at each 2 monthly follow-up visit during 6 months. The frequencies of QLQ-C30 score improvement were calculated and mixed models for repeated measurements were applied with or without extreme poorest imputation for missing scores. The "survival" until definitive global health score (GHS) deterioration was estimated. RESULTS: At the 3rd follow-up, patients with a stable or improved global health ranged from 11% in the LV5FU2-cisplatin arm to 18% in the LV5FU2-irinotecan arm. The irinotecan-based-therapy presented 14 to 15 scores with a better QoL. The time until definitive GHS deterioration was globally similar between treatment arms. CONCLUSION: This study highlights a better impact of LV5FU2-irinotecan and the interest of QoL assessment in phase II trials to complement the risk-benefit judgement.
