Prognostic value of health-related quality of life in patients with metastatic pancreatic adenocarcinoma: a random forest methodology.

PURPOSE: Eastern Cooperative Oncology Group Performance Status (ECOG-PS) is currently an important parameter in the choice of treatment strategy for metastatic pancreatic adenocarcinoma (mPA) patients. However, previous research has shown that patients' self-reported health-related quality of life (HRQOL) scales provided additional prognostic information in homogeneous groups of patients with respect to ECOG-PS. The aim of this study was to identify HRQOL scales with independent prognostic value in mPA and to propose prognostic groups for these patients. METHODS: We analysed data from 98 chemotherapy-naive patients with histologically proven mPA recruited from 2007 to 2011 in the FIRGEM phase II study which aimed to compare the effectiveness of two chemotherapy regimen. HRQOL data were assessed with the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire. A random survival forest methodology was used to impute missing data and to identify major prognostic factors for overall survival. RESULTS: Baseline HRQOL assessment was completed by 60 % of patients (59/98). Twelve prognostic variables were identified. The three most important prognostic variables were fatigue, appetite loss, and role functioning, followed by three laboratory variables. The model's discriminative power assessed by Harrell's C statistic was 0.65. Fatigue score explained almost all the survival variability. CONCLUSION: HRQOL scores have prognostic value for mPA patients with good ECOG-PS. Moreover, the patient's fatigue, appetite loss, and self-perception of daily activities were more reliable prognostic indicators than clinical and laboratory variables. These HRQOL scores, especially the fatigue symptom, should be urgently included for prognostic assessment of mPA patients (with good ECOG-PS).

Second-line chemotherapy for advanced biliary tract cancer after failure of the gemcitabine-platinum combination: A large multicenter study by the Association des Gastro-Entérologues Oncologues.

BACKGROUND: Few data are available on second-line chemotherapy (CT2) for advanced biliary tract cancer (ABTC). The aim of this multicenter study was to describe the CT2 regimens used, the response rates, and the outcomes of patients treated with various CT2 regimens. METHODS: Patients who received CT2 for ABTC at 17 French institutions after the failure of the gemcitabine-platinum combination were retrospectively studied. Progression-free survival (PFS) and overall survival (OS) were estimated with the Kaplan-Meier method. Cox models were used for multivariate analyses. RESULTS: Among 603 patients who received first-line chemotherapy (CT1) for ABTC, 196 received CT2: 5-fluorouracil (5-FU) and irinotecan (n = 64), 5-FU and oxaliplatin (n = 21), 5-FU and cisplatin (n = 38), 5-FU or capecitabine (n = 40), sunitinib (n = 10), or other various regimens (n = 23). Among the 186 assessable patients, there were 22 partial responses and 70 stabilizations. After a median follow-up of 26.4 months, the median PFS and OS were 3.2 and 6.7 months, respectively. There was no significant difference in PFS or OS between CT2 regimens. Fluoropyrimidine-based doublet chemotherapy was not superior to fluoropyrimidine alone in terms of OS and PFS. In a multivariate analysis, a performance status of 0 to 1, disease control with CT1, and a carbohydrate antigen 19-9 (CA 19-9) level ≤ 400 IU/mL were significantly associated with longer PFS and OS. Grade 3 to 4 toxicity occurred in 32% of the patients. CONCLUSIONS: CT2 might provide disease control for selected patients with ABTC after the failure of gemcitabine-platinum, but the prognosis remains poor. No particular regimen seems superior to others, and this calls for new treatments. A good performance status, disease control with CT1, and a low level of CA 19-9 were associated with longer survival.

FOLFOX as second-line chemotherapy in patients with pretreated metastatic pancreatic cancer from the FIRGEM study.

BACKGROUND: FOLFOX second-line treatment seems to be a validated option for patients with pancreatic cancer (PC) progressing after gemcitabine chemotherapy. However, other therapeutics strategy has developed in first-line therapy, as the FIRGEM phase II study that evaluated gemcitabine alone versus FOLFIRI.3 alternating with gemcitabine every two months. The present study assessed the efficacy and safety of FOLFOX after failure of the first-line therapy used in the FIRGEM study. METHODS: In this prospective observational cohort study, we analysed all consecutive patients who received second-line chemotherapy with FOLFOX among 98 patients with metastatic PC included in the FIRGEM study. Progression-free survival (PFS) and overall survival (OS) were estimated from the start of second-line chemotherapy using the Kaplan-Meier method. RESULTS: Among 46 patients who received second-line chemotherapy, 27 patients (male, 55%; median age, 61 years; performance status (PS) 0-1, 44%) were treated with FOLFOX after progression to first-line gemcitabine alone (n = 20) or FOLFIRI.3 alternating with gemcitabine (n = 7). Grade 3 toxicity was observed in 33% of patients (no grade 4 toxicity). At the end of follow-up, all patients had progressed and 25 had died. No objective response was observed, and disease control rate was 36%. Median PFS and OS were 1.7 and 4.3 months, respectively. In multivariate analysis, PS was the only independent prognostic factor. For patients PS 0-1 versus 2-3, median PFS was 3.0 versus 1.2 months (log rank, p = 0.002), and median OS was 5.9 versus 2.6 months (log rank, p = 0.001). CONCLUSIONS: This study suggests that FOLFOX second-line therapy offered interesting efficacy results with an acceptable toxicity profile in metastatic PC patients with a good PS.

Gemcitabine and Paclitaxel Versus Gemcitabine Alone After 5-Fluorouracil, Oxaliplatin, and Irinotecan in Metastatic Pancreatic Adenocarcinoma: A Randomized Phase III PRODIGE 65-UCGI 36-GEMPAX UNICANCER Study.

PURPOSE: GEMPAX was an open-label, randomized phase III clinical trial designed to assess the efficacy and tolerability of gemcitabine plus paclitaxel versus gemcitabine alone as second-line treatment for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) who previously received 5-fluorouracil, oxaliplatin, and irinotecan. METHODS: Patients with histologically or cytologically confirmed mPDAC were randomly assigned (2:1) to receive GEMPAX (paclitaxel 80 mg/m2 + gemcitabine 1,000 mg/m2; IV; once at day (D) 1, D8, and D15/arm A) or gemcitabine (arm B) alone once at D1, D8, and D15 every 28 days until progression, toxicity, or patient's decision. The primary end point was overall survival (OS). Secondary end points included progression-free survival (PFS), objective response rate (ORR), quality of life, and safety. RESULTS: Overall, 211 patients (median age, 64 [30-86] years; 62% male) were included. After a median study follow-up for alive patients of 13.4 versus 13.8 months in arm A versus arm B, the median OS (95% CI) was 6.4 (5.2 to 7.4) versus 5.9 months (4.6 to 6.9; hazard ratio [HR], 0.87 [0.63 to 1.20]; P = 0.4095), the median PFS was 3.1 (2.2 to 4.3) versus 2.0 months (1.9 to 2.3; HR, 0.64 [0.47 to 0.89]; P = 0.0067), and the ORR was 17.1% (11.3 to 24.4) versus 4.2% (0.9 to 11.9; P = 0.008) in arm A versus arm B, respectively. Overall, 16.7% of patients in arm A and 2.9% in arm B discontinued their treatment because of adverse events (AEs). One grade 5 AE associated with both gemcitabine and paclitaxel was reported in arm A (acute respiratory distress), and 58.0% versus 27.1% of patients experienced grade ≥3 treatment-related AEs in arm A versus arm B, among which 15.2% versus 4.3% had anemia, 15.9% versus 15.7% had neutropenia, 19.6% versus 4.3% had thrombocytopenia, 10.1% versus 2.9% had asthenia and 12.3% versus 0.0% had neuropathy. CONCLUSION: While GEMPAX did not meet the primary end point of OS versus gemcitabine alone in patients with mPDAC in the second-line setting, both PFS and ORR were significantly improved.

Multicentre, interventional, single-arm study protocol of telemonitored circadian rhythms and patient-reported outcomes for improving mFOLFIRINOX safety in patients with pancreatic cancer (MultiDom, NCT04263948).

INTRODUCTION: Circadian clocks regulate cellular proliferation and drug effects. Tolerability and/or efficacy of anticancer therapies have been improved by their administration according to circadian rhythms, while being predicted by circadian robustness. The combination of leucovorin, fluorouracil, irinotecan and oxaliplatin (mFOLFIRINOX) is a standard treatment for pancreatic ductal adenocarcinoma (PDAC), that generates grades 3-4 adverse events in the majority of patients and an estimated 15%-30% emergency admission rate. The MultiDom study evaluates whether mFOLFIRINOX safety can be improved using a novel circadian-based telemonitoring-telecare platform in patients at home. The detection of early warning signals of clinical toxicities could guide their early management, possibly preventing emergency hospital admissions. METHODS AND ANALYSIS: This multicentre, interventional, prospective, longitudinal, single-arm study hypothesises that the mFOLFIRINOX-related emergency admission rate will be 5% (95% CI 1.7% to 13.7%), among 67 patients with advanced PDAC. Study participation is 7 weeks for each patient, including a reference week before chemotherapy onset and 6 weeks afterwards. Accelerometry and body temperature are measured q1-min using a continuously worn telecommunicating chest surface sensor, daily body weight is self-measured with a telecommunicating balance and 23 electronic patient-reported outcomes (e-PROs) are self-rated using a tablet. Hidden Markov model, spectral analyses and other algorithms automatically compute physical activity, sleep, temperature, body weight change, e-PRO severity and 12 circadian sleep/activity parameters, including the dichotomy index I

Circulating tumour DNA at baseline for individualised prognostication in patients with chemotherapy-naïve metastatic colorectal cancer. An AGEO prospective study.

PURPOSE: Baseline circulating tumour DNA (ctDNA) is a potential prognostic marker in metastatic colorectal cancer (mCRC) patients. However, few studies have compared ctDNA with the usual prognostic factors, and no ctDNA cut-off has been proposed for daily use in clinical practice. PATIENTS AND METHODS: Chemotherapy-naive patients with mCRC were prospectively included. Plasma samples were collected at diagnosis and analysed centrally by both NGS and methylation digital PCR. Baseline patient and disease characteristics, treatment regimens, and secondary surgeries were collected. The restricted cubic spline method was used to define the optimal cut-off of ctDNA mutated allelic frequency (MAF). Prognostic values were assessed on overall survival (OS) using Cox models. RESULTS: From July 2015 to December 2016, 412 patients were included. ctDNA was undetectable in 83 patients (20%). ctDNA was an independent prognostic marker for OS considering the whole study population. The optimal cut-off for ctDNA MAF was 20% with median OS of 16.0 and 35.8 months for patients with MAF ≥20% and<20%, respectively (hazard ratio = 0.40; 95% confidence intervals: 0.31-0.51; P < 0.0001). The independent prognostic value of ctDNA MAF at 20% was confirmed in subgroups defined by RAS/BRAF status or resectability of metastases. Combining ctDNA MAF and carcinoembryonic antigen levels allowed us to define three different prognostic groups with median OS of 14.2, 21.1, and 46.4 months (P < 0.0001). CONCLUSION: ctDNA with a MAF cut-off of 20% improves prognostication of chemotherapy-naïve mCRC patients and may be useful in the future for individualised therapeutic decisions and as a stratification factor in clinical trials.

Phase III randomized trial comparing systemic versus intra-arterial oxaliplatin, combined with LV5FU2 +/- irinotecan and a targeted therapy, in the first-line treatment of metastatic colorectal cancer restricted to the liver (OSCAR): PRODIGE 49.

INTRODUCTION: In patients with unresectable liver metastases from colorectal cancer (CRCLM), systemic doublet or triplet chemotherapy and targeted therapy is considered a standard first-line treatment. Hepatic arterial infusion of oxaliplatin (HAI-ox) generates a high response rate, but this still needs to be confirmed in a randomized trial. We incorporated HAI-ox in doublet or triplet + targeted therapy to validate its efficacy. AIM: The OSCAR study is an ongoing randomized phase III trial comparing FOLFOX + targeted therapy according to RAS status, or FOLFOXIRI + bevacizumab in patients eligible for triplet therapy, with the same regimen but with HAI-ox instead of IV-ox as the first-line treatment for CRCLM. MATERIALS AND METHODS: Main eligibility criteria are colorectal cancer, unresectable liver metastasis, no extra-hepatic metastases except pulmonary nodules if ≤3 and <10 mm, ECOG performance status 0 or 1. ENDPOINT: The primary endpoint is progression-free survival (PFS). A difference of 4 months for the median PFS in favor of HAI-ox is expected (HR = 0.73). Secondary endpoints include overall survival, overall response rate, secondary liver resection, safety, and quality of life. CONCLUSION: This study is planned to include 348 patients to demonstrate the superiority of HAI-ox over systemic oxaliplatin in first-line CRCLM treatment (NCT02885753).

Gemcitabine plus nab-paclitaxel until progression or alternating with FOLFIRI.3, as first-line treatment for patients with metastatic pancreatic adenocarcinoma: The Federation Francophone de Cancérologie Digestive-PRODIGE 37 randomised phase II study (FIRGEMAX).

BACKGROUND: Chemotherapy is effective in metastatic pancreatic adenocarcinoma (mPA), but new approaches are still needed to improve patients' survival and quality of life. We have previously published good efficacy and tolerability results on a sequential treatment strategy of gemcitabine followed by an intensified FOLFIRI (5FU+irinotecan) regimen. In the present study, we evaluated the same sequence but replaced gemcitabine by the new gemcitabine + nab-paclitaxel standard first-line combination. PATIENTS AND METHODS: We randomised chemotherapy-naive patients with proven mPA, bilirubin levels ≤1.5 upper limit of normal values and performance status 0-2 to alternately receive gemcitabine + nab-paclitaxel for 2 months then FOLFIRI.3 for 2 months in arm A, or gemcitabine + nab-paclitaxel alone until progression in arm B. The primary objective was to increase the 6-month progression-free survival (PFS) rate from 40% (H0) to 60% (H1); using the binomial exact method, 124 patients were required. Analyses were carried out in preplanned modified intention-to-treat (mITT) and per-protocol (PP) populations. RESULTS: Between November 2015 and November 2016, 127 patients were enrolled. Main grade III-IV toxicities (% in arm A/B) were: diarrhoea (12.5/1.7), neutropenia (46.9/31, including febrile neutropenia: 1.6/0), skin toxicity (6.3/13.8), and peripheral neuropathy (6.3/8.6). No toxic deaths occurred. The objective response rate was 40.3% (95% confidence interval [CI]: 28.1-53.6) in arm A and 26.7% (95% CI: 16.1-39.7) in arm B. The primary end-point (6-month PFS rate) was 45.2% [one-sided 95% CI: 34.3-56.4] in arm A and 23.3% in arm B [one-sided 95% CI: 14.3-32.3] in the mITT population. In the PP population, median PFS and OS were 7.6 months and 6 months and 14.5 months and 12.2 months in arm A and B, respectively. CONCLUSIONS: The FIRGEMAX strategy with gemcitabine + nab-paclitaxel alternating with FOLFIRI.3 every 2 months, appears feasible and effective, with manageable toxicities, in patients able to reach >2mo of treatment.

BRAF Mutation Status in Circulating Tumor DNA from Patients with Metastatic Colorectal Cancer: Extended Mutation Analysis from the AGEO RASANC Study.

In patients with metastatic colorectal cancer (mCRC), RAS and BRAF mutations are currently determined by tumor sample analysis. Here, we report BRAF mutation status analysis in paired tumor tissue and plasma samples of mCRC patients included in the AGEO RASANC prospective cohort study. Four hundred and twenty-five patients were enrolled. Plasma samples were analyzed by next-generation sequencing (NGS). When no mutation was identified, we used two methylated specific biomarkers (digital droplet PCR) to determine the presence or absence of circulating tumor DNA (ctDNA). Patients with conclusive ctDNA results were defined as those with at least one mutation or one methylated biomarker. The kappa coefficient and accuracy were 0.79 (95% CI: 0.67-0.91) and 97.3% (95% CI: 95.2-98.6%) between the BRAF status in plasma and tissue for patients with available paired samples (n = 405), and 0.89 (95% CI: 0.80-0.99) and 98.5% (95% CI: 96.4-99.5%) for those with conclusive ctDNA (n = 323). The absence of liver metastasis was the main factor associated to inconclusive ctDNA results. In patients with liver metastasis, the kappa coefficient was 0.91 (95% CI, 0.81-1.00) and accuracy was 98.6% (95% CI, 96.5-99.6%). We demonstrate satisfying concordance between tissue and plasma BRAF mutation detection, especially in patients with liver metastasis, arguing for plasma ctDNA testing for routine BRAF mutation analysis in these patients.

Folfirinox versus gemcitabine/nab-paclitaxel as first-line therapy in patients with metastatic pancreatic cancer: a comparative propensity score study.

BACKGROUND: Folfirinox (FFX) and gemcitabine/nab-paclitaxel (GN) are both standard first-line treatments in patients with metastatic pancreatic cancer (mPC). However, data comparing these two chemotherapeutic regimens and their sequential use remain scarce. METHODS: Data from two independent cohorts enrolling patients treated with FFX (n = 107) or GN (n = 109) were retrospectively pooled. Primary endpoint was overall survival (OS). Progression-free survival (PFS) was the secondary endpoint. A propensity score based on age, gender, performance status (PS), and presence of liver metastases was used to make groups comparable. RESULTS: In the whole study population, OS was significantly higher in FFX (14 months; 95% CI: 10-21) than in GN groups (9 months; 95% CI: 8-12) before (p = 0.008) and after (p = 0.021) adjusting for age, number of metastatic sites, liver metastases, peritoneal carcinomatosis and CA19.9 level at baseline. PFS tends to be higher in FFX (6 months) than GN groups (5 months; p = 0.053). After matching (n = 49/group), patients were comparable for all baseline characteristics including PS. In the matched population, there was a trend toward greater OS in patients treated with FFX (HR = 0.67; p = 0.097). However, survival in each group was not solely a result of the first-line regimen. The proportion of patients who were fit for GN after FFX failure (FFX-GN sequence) was higher (46.9%) than the reverse sequence (20.4%; p = 0.01), which suggests a higher feasibility for the FFX-GN sequence. Corresponding median OS were 19 months versus 9.5 months, respectively (p = 0.094). CONCLUSION: This study shows greater OS with FFX than with GN in patients with mPC. GN after FFX failure appears more feasible than the reverse sequence.

[Fatal liver failure after hepatitis B reactivation following chemotherapy for lymphoma in a patient with only anti-HBc antibody and review of the literature]. / Evolution fatale après réactivation d'une hépatite chronique virale B occulte dans les suites d'une chimiothérapie pour lymphome chez un malade porteur de l'anticorps anti-HBc isolé

Hepatitis B reactivation after chemotherapy is well known when Ag HBs is positive. Recommendation is to give preventive antiviral treatment before starting chemotherapy. The reactivation when there is only an anti-HBc antibody is rare. We report the case of a woman who developed an hepatitis B reactivation two weeks after the end of a chemotherapy for a high grade non Hodgkin lymphoma. Before chemotherapy, hepatitis B virus serology was positive only for anti-HBc antibody and viral load was negative. She had a fulminant hepatitis with fatal issue although a treatment by lamivudine and adefovir was rapidly started. In the literature, only 13 cases of patients with positive anti body anti-HBc alone who developed an hepatitis B reactivation after chemotherapy have been reported.

[Duodenal duplication revealed by acute pancreatitis: endoscopic treatment]. / Duplication duodénale révélée par une pancréatite aiguë: traitement endoscopique.

We report the case of a 17 year old man who presented with several episodes of acute pancreatitis due to a duodenal duplication. This was successfully treated by an incision by sphincterotome during interventional duodenoscopy. The patient is symptom free without recurrence 20 months after endoscopic treatment.

[Pancreatic intraductal tubular carcinoma: a sub-group of intraductal papillary-mucinous tumors or a distinct entity? A case report and review of the literature]. / Carcinome tubuleux intracanalaire pancréatique: sous-groupe ou entité distincte des tumeurs intracanalaires papillaires mucineuses? A propos d'un cas et revue de la littérature.

We report the case of a 67-year-old man presenting with an isolated 3 cm mass of the pancreatic tail revealed by weight loss. Distal pancreatectomy and splenectomy were performed. Microscopically, the tumor filled the main pancreatic duct, extending into the smaller ducts and was associated with a minor adenocarcinomatous invasive component. The intraductal tumor showed a cribriform pattern, atypical cells without mucus and a MUC1+, MUC2-, MUC5AC- phenotype, all characteristics of intraductal tubular carcinoma, a new entity described by Japanese authors. The differential diagnosis and its relationship with intraductal papillary-mucinous tumors are discussed.

[A probable case of alveolar echinococcosis in Normandy, France]. / Un cas probable d'échinococcose alvéolaire en Normandie.

Echinococcus multilocularis induced liver infection was diagnosed in a Moroccan patient. Diagnosis was based on CT scan results and Western Blot test. Contamination probably occurred in France, in the Cherbourg area where the patient travelled frequently and ate wild berries. This case and other recently reported cases outside the usual endemic areas (Besançon and the Massif Central) suggest that the Echinococcus multilocularis epidemic has moved towards the west of France. French gastroenterologists should be aware of this parasitic disease.

Fixed-dose rate gemcitabine alone or alternating with FOLFIRI.3 (irinotecan, leucovorin and fluorouracil) in the first-line treatment of patients with metastatic pancreatic adenocarcinoma: an AGEO randomised phase II study (FIRGEM).

BACKGROUND: Fluorouracil and irinotecan-based, and gemcitabine-based regimens, are the standard of care in the first-line treatment of patients with metastatic pancreatic cancer. New approaches are needed to improve survival and quality of life. Whether a sequential approach alternating irinotecan, fluorouracil and gemcitabine may be effective and tolerable in patients with metastatic pancreatic cancer is unknown. METHODS: In this randomised, multicentre, open-label, phase 2 trial, patients with metastatic pancreatic adenocarcinoma, World Health Organisation (WHO) performance status 0-1, and bilirubin levels <1.5 upper limit of normal values (ULN) were randomised 1:1 to receive as first-line treatment either FOLFIRI.3 (irinotecan, leucovorin and fluorouracil) alternating with fixed-dose rate gemcitabine as 2-month periods (FIRGEM, arm A), or fixed-dose rate gemcitabine alone (arm B). Treatment was continued until disease progression or limiting toxicity. The primary end-point was the crude progression-free survival (PFS) rate at 6 months. The study is registered with EudraCT (N° 2006-005703-34). RESULTS: Between October 2007 and March 2011, 98 patients were enroled. The observed 6-month PFS rate was 43.5% (95% confidence interval (CI), [28.6-58.4%]) in arm A reaching the Fleming decision rules criteria to reject H0 and 26.1% (95% CI [12.9-39.3%]) in arm B. Objective response rates were 37% (23-51%) in arm A and 10% (1-19%) in arm B. Median PFS (5.0 versus 3.4 months, hazard ratio (HR)=0.59 [0.38-0.90]) and overall survival (11.0 versus 8.2 months, HR=0.71 [0.46-1.10]) were higher in arm A compared to arm B. The most frequent grade 3-4 toxicities were neutropenia (49%/24%; febrile neutropenia, 4%/0% in arms A/B), diarrhoea (arm A, 12% and arm B, 0%), and nausea/vomiting (8%/4%). No toxic deaths occurred. CONCLUSION: The FIRGEM strategy appears to be effective and feasible in patients with metastatic pancreatic cancer.

Second-line chemotherapy with fluorouracil, leucovorin, and irinotecan (FOLFIRI regimen) in patients with advanced small bowel adenocarcinoma after failure of first-line platinum-based chemotherapy: a multicenter AGEO study.

BACKGROUND: Small bowel adenocarcinoma (SBA) is a rare tumor with poor prognosis. First-line platinum-based chemotherapy is active in patients with advanced SBA, but data regarding second-line chemotherapy are lacking. The aim of this study was to evaluate the efficacy and tolerability of fluorouracil, leucovorin, and irinotecan (FOLFIRI regimen) as second-line chemotherapy in patients with advanced SBA. METHODS: We analyzed all consecutive patients who received second-line chemotherapy with FOLFIRI among 93 patients with advanced SBA included from 1996 to 2008 in a previous retrospective multicenter study. Progression-free survival (PFS) and overall survival (OS) were estimated from the start of second-line chemotherapy using the Kaplan-Meier method. Cox models were applied for multivariate analyses. RESULTS: Among 51 patients who received second-line chemotherapy, 28 patients (male, 57%; median age, 54 years; metastatic disease, 96%) were treated with FOLFIRI after progression (n = 24) or limiting toxicity (n = 4) to first-line FOLFOX (n = 19) or LV5FU2-cisplatin (n = 9). Grade 3-4 toxicity was observed in 48% of patients (grade 3-4 neutropenia, 37%). After a median follow-up of 21.5 months, all patients had tumor progression, and 22 patients died. Objective response rate was 20%, and disease control rate was 52%. Median PFS and OS were 3.2 and 10.5 months, respectively. No clinical, biological, or tumor characteristics were associated with PFS or OS by multivariate analysis. CONCLUSIONS: Second-line chemotherapy with FOLFIRI produced disease control in half of patients with advanced SBA after failure with first-line platinum-based chemotherapy. Nevertheless, the short median PFS warrants the evaluation of other treatments including targeted therapies.
