A randomized phase III trial comparing trabectedin to best supportive care in patients with pre-treated soft tissue sarcoma: T-SAR, a French Sarcoma Group trial.

BACKGROUND: The French Sarcoma Group assessed the efficacy, safety, and quality of life (QoL) of trabectedin versus best supportive care (BSC) in patients with advanced soft tissue sarcoma (STS). PATIENTS AND METHODS: This randomized, multicenter, open-label, phase III study included adults with STS who progressed after 1-3 prior treatment lines. Patients were randomized (1 : 1) to receive trabectedin 1.5 mg/m2 every 3 weeks or BSC, stratified into L-STS (liposarcoma/leiomyosarcoma) and non-L-STS groups (other histotypes). Patients from the BSC arm were allowed to cross over to trabectedin at progression. The primary efficacy endpoint was progression-free survival (PFS) confirmed by blinded central review and analyzed in the intention-to-treat population. RESULTS: Between 26 January 2015 and 5 November 2015, 103 heavily pre-treated patients (60.2% with L-STS) from 16 French centers were allocated to receive trabectedin (n = 52) or BSC (n = 51). Median PFS was 3.1 months [95% confidence interval (CI) 1.8-5.9 months] in the trabectedin arm versus 1.5 months (0.9-2.6 months) in the BSC arm (hazard ratio = 0.39, 95% CI 0.24-0.64, P < 0.001) with benefits observed across almost all analyzed subgroups, but particularly in patients with L-STS (5.1 versus 1.4 months, P = 0.0001). Seven patients (13.7%) in the trabectedin arm (all with L-STS) achieved a partial response, while no objective responses were observed in the BSC arm (P = 0.004). The most common grade 3/4 adverse events were neutropenia (44.2% of patients), leukopenia (34.6%), and transaminase increase (32.7%). Health-related 30-item core European Organization for the Research and Treatment of Cancer Quality-of-Life Questionnaire evidenced no statistical differences between the arms for any domain and at any time point. After progression, 91.8% of patients crossed over from BSC to trabectedin. CONCLUSION: Trabectedin demonstrates superior disease control to BSC without impairing QoL in patients with recurrent STS of multiple histologies, with greater impact in patients with L-STS.

Reduced-intensity versus reduced-toxicity myeloablative fludarabine/busulfan-based conditioning regimens for allografted non-Hodgkin lymphoma adult patients: a retrospective study on behalf of the Société Francophone de Greffe de Moelle et de Thérapie Cellulaire.

BACKGROUND: Fludarabine/busulfan-based conditioning regimens are widely used to perform allogeneic stem-cell transplantation (allo-SCT) in high-risk non-Hodgkin lymphoma (NHL) patients. The impact of the dose intensity of busulfan on outcomes has not been reported yet. PATIENTS AND METHODS: This was a retrospective with the aim to compare the outcomes of NHL patients who received before allo-SCT a fludarabine/busulfan conditioning regimen, either of reduced intensity (FB2, 2 days of busulfan at 4 mg/kg/day oral or 3.2 mg/kg/day i.v.) (n = 277) or at a myeloablative reduced-toxicity dose (FB3/FB4, 3 or 4 days of busulfan at 4 mg/kg/day oral or 3.2 mg/kg/day i.v.) (n = 101). RESULTS: In univariate analysis, the 2-year overall survival (FB2 66.5% versus 60.3%, P = 0.33), lymphoma-free survival (FB2 57.9% versus 49.8%, P = 0.26), and non-relapse mortality (FB2 19% versus 21.1%, P = 0.91) were similar between both groups. Cumulative incidence of grade III-IV acute graft versus host disease (GVHD) (FB2 11.2% versus 18%, P = 0.08), extensive chronic GVHD (FB2: 17.3% versus 10.7%, P = 0.18) and 2-year GVHD free-relapse free survival (FB2: 44.4% versus 42.8%, P = 0.38) were also comparable. In multivariate analysis there was a trend for a worse outcome using FB3/FB4 regimens (overall survival: HR 1.47, 95% CI: 0.96-2.24, P = 0.08; lymphoma-free survival: HR: 1.43, 95% CI: 0.99-2.06, P = 0.05; relapse incidence: HR 1.54; 95% CI: 0.96-2.48, P = 0.07). These results were confirmed using a propensity score-matching strategy. CONCLUSION: We conclude that reduced toxicity myeloablative conditioning with fludarabine/busulfan does not improve the outcomes compared with reduced-intensity conditioning in adults receiving allo-SCT for NHL.

Prediction of local and metastatic recurrence in solitary fibrous tumor: construction of a risk calculator in a multicenter cohort from the French Sarcoma Group (FSG) database.

BACKGROUND: Solitary fibrous tumors (SFT) are rare unusual ubiquitous soft tissue tumors that are presumed to be of fibroblastic differentiation. At present, the challenge is to establish accurate prognostic factors. PATIENTS AND METHODS: A total of 214 consecutive patients with SFT diagnosed in 24 participating cancer centers were entered into the European database (www.conticabase.org) to perform univariate and multivariate analysis for overall survival (OS), local recurrence incidence (LRI) and metastatic recurrence incidence (MRI) by taking competing risks into account. A prognostic model was constructed for LRI and MRI. Internal and external validations of the prognostic models were carried out. An individual risk calculator was carried out to quantify the risk of both local and metastatic recurrence. RESULTS: We restricted our analysis to 162 patients with local disease. Twenty patients (12.3%) were deceased at the time of analysis and the median OS was not reached. The LRI rates at 10 and 20 years were 19.2% and 38.6%, respectively. The MRI rates at 10 and 20 years were 31.4% and 49.8%, respectively. Multivariate analysis retained age and mitotic count tended to significance for predicting OS. The factors influencing LRI were viscera localization, radiotherapy and age. Mitotic count, tumor localization other than limb and age had independent values for MRI. Three prognostic groups for OS were defined based on the number of unfavorable prognostic factors and calculations were carried out to predict the risk of local and metastatic recurrence for individual patients. CONCLUSION: LRI and MRI rates increased between 10 and 20 years so relapses were delayed, suggesting that long-term monitoring is useful. This study also shows that different prognostic SFT sub-groups could benefit from different therapeutic strategies and that use of a survival calculator could become standard practice in SFTs to individualize treatment based on the clinical situation.

Retroperitoneal sarcomas: patterns of care at diagnosis, prognostic factors and focus on main histological subtypes: a multicenter analysis of the French Sarcoma Group.

BACKGROUND: Retroperitoneal sarcomas (RPS) are heterogeneous. No previous study has investigated the impact of specialized surgery, evaluated locoregional relapse (LRR), abdominal sarcomatosis and distant metastatic relapse as separate events, or considered histological subtypes separately. This study addresses these specific points in a homogeneous cohort of patients with completely resected primary RPS. PATIENTS AND METHODS: We conducted a retrospective analysis of adult patients diagnosed with a RPS between 1 January 1988 and 31 December 2008 and eventually referred to one of 12 centers of the French Sarcoma Group. All cases were centrally reviewed by an expert pathologist. RESULTS: Five hundred eighty-six patients were included. Median follow-up was 6.5 years [95% confidence interval (CI) 5.9-7.1]. Five hundred thirty-seven patients had localized disease and 389 patients (76%) had macroscopically complete resection of the tumor. In this latter group, the 5-year LRR-free survival rate was 46% [41-52] and the 5-year overall survival (OS) rate was 66% [61-71]. In multivariate analysis, gender, adjacent organ involvement, specialization of the surgeon, piecemeal resection and perioperative radiotherapy were independently associated with LRR. Specialization of the surgeon and piecemeal resection were independently associated with abdominal sarcomatosis whereas histology and adjacent organ involvement were independently associated with distant metastasis. Age, gender, grade, adjacent organ involvement and piecemeal resection were significantly associated with OS. Prognostic factors for LRR and OS were analyzed in well-differentiated and dedifferentiated liposarcomas and leiomyosarcomas. Grade 3 was an independent prognostic factor for OS of dedifferentiated liposarcomas. CONCLUSION: This study underlines the crucial role of pretherapeutic assessment and meticulous histological examination of RPS as well as the need to consider histological subtypes separately. Surgery in a specialized center and avoidance of piecemeal resection stand out as the two most important prognostic factors for RPS and highlight the importance of treating these patients in specialized centers.

Adjuvant radiotherapy for extremity and trunk wall atypical lipomatous tumor/well-differentiated LPS (ALT/WD-LPS): a French Sarcoma Group (GSF-GETO) study.

BACKGROUND: The role of adjuvant radiotherapy (RT) in the management of atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WD-LPS) remains controversial. METHODS: Two hundred eighty-three patients with operable ALT/WD-LPS, no history of previous cancer, chemotherapy (CT) or RT, treated between 1984 and 2011 registered in the Conticabase database were included and described. Overall (OS), progression-free survival (PFS) and time to local relapse (TTLR) were evaluated from the time of first treatment. RESULTS: Three of 20 centers enrolled 58% of the patients. Median age at diagnosis was 61 (range 25-94) years, 147 patients (52%) were males, 222 (78%) patients had their primary tumor located in an extremity while 36 (13%) and 25 (9%) had tumors involving the girdle and the trunk wall, respectively. The median size of primary tumors was 17 cm (range 2-48 cm). Adjuvant RT was given to 132 patients (47%). Patients who received adjuvant RT had larger tumors (P = 0.005), involving more often the distal limbs (P < 0.001). Use of adjuvant RT varied across centers and along the study period. Other characteristics were balanced between the two groups. Median follow-up was 61.7 months. None of the patients developed metastasis during follow-up. The 5-year local relapse-free survival rates were 98.3% versus 80.3% with and without adjuvant RT, respectively (P < 0.001). Once stratified on time period (before/after 2003), adjuvant RT, tumor site and margin status (R0 versus other) were independently associated with TTLR. No OS difference was observed (P = 0.105). CONCLUSION: In this study, adjuvant RT following resection of ALT/WD-LPS was associated with a reduction of LR risk.

Retroperitoneal sarcomas: patterns of care in advanced stages, prognostic factors and focus on main histological subtypes: a multicenter analysis of the French Sarcoma Group.

BACKGROUND: Retroperitoneal sarcomas (RPS) are heterogeneous. Advanced stages include unresectable locoregional (LR) disease, abdominal sarcomatosis and distant metastasis. There is no available report assessing palliative chemotherapy in advanced RPS. This study analyzes management and outcome in a large cohort of patients with advanced RPS, considering main histological subtypes separately. PATIENTS AND METHODS: We conducted a retrospective analysis of adult patients diagnosed with a RPS between 1 January 1988 and 31 December 2008 across 12 centers of the French Sarcoma Group. All cases were centrally reviewed by an expert pathologist. RESULTS: Five-hundred eighty-six patients were included, 299 patients received palliative chemotherapy, with a median of two lines (range 0-8). Fifty patients underwent palliative surgery. Two hundred fifty-five patients (85%) were assessable for response after first line of chemotherapy. Among them, 69 patients (27%) had progressive disease, 145 (57%) had stable disease, 37 (14.5%) had partial response and 4 (1.5%) complete response. Median time from first line of palliative chemotherapy to progression was 5.9 months [4.9-7.3] and median overall survival (OS), 15.8 months [13-18]. In multivariate analysis, prognosis factors independently associated with poor OS were male gender, performance status (PS) >1 and grade >1. There was no difference according to stage of disease. Palliative surgery did not appear to add any survival benefit. CONCLUSION: These results emphasize the scarcity of available options for RPS in the advanced setting and the urgent need to develop new strategies. Patients with good PS should be included in clinical trials and best supportive care should be considered in those with poor PS.

A phase II trial of high-dose chemotherapy (HDCT) supported by hematopoietic stem-cell transplantation (HSCT) in germ-cell tumors (GCTs) patients failing cisplatin-based chemotherapy: the Multicentric TAXIF II study.

BACKGROUND: High-dose chemotherapy (HDCT) is an effective salvage treatment of germ-cell tumors (GCTs) patients. In the first salvage setting, 30%-70% of patients may achieve durable remissions. Even when HDCT is administered as subsequent salvage treatment, up to 20% of patients may still be definitively cured. However, patients with refractory/relapsed disease still have a very poor long-term prognosis, requiring earlier intervention of HDCT. PATIENTS AND METHODS: This phase II trial was addressed to nonrefractory patients failing Cisplatin-based chemotherapy. Inclusion criteria included seminomatous GCT in relapse after two lines of chemotherapy, nonseminomatous GCT in relapse after first or second lines, partial remission after first line, primary mediastinal GCT in first relapse. Patients received two cycles combining Epirubicin and Paclitaxel (Epi-Tax), followed by three consecutive HDCT, one using a Paclitaxel/Thiotepa (Thio-Tax) association and two using the 5-day Ifosfamide-Carboplatin-Etoposide regimen. The main objective was to determine the complete response rate. RESULTS: Forty-five patients were included between September 2004 and December 2007: 44 received the first HDCT cycle, 39 two HDCT cycles, 29 could receive the whole protocol. Sixteen patients did not receive the entire protocol, including eight (17.7%) for toxic side-effects. Two patients (4.4%) died of toxicities, and 17 (37.7%) of disease progression. With a median follow-up time of 26 months (range, 4-51), the final overall response rate was 48.8% (including a complete response rate of 15.5% and a partial response/negative serum markers rate of 26.6%) in an intent-to-treat analysis. The median progression-free survival (PFS) and overall survival (OS) times were 22 months [95% confidence interval (CI) 2-not reached] and 32 months (95% CI 4-49), respectively. The 2-year PFS was a plateau setup at 50% (95% CI 32-67) and the 2-year OS was 66% (95% CI 44-81). CONCLUSION: The TAXIF II protocol was effective in nonrefractory GCT patients failing Cisplatin-based chemotherapy. The toxic death rate remained acceptable in the field of HDCT regimens. TRIAL REGISTRATION NUMBER: NCT00231582.

[Allogeneic stem cell transplantation from an HLA-haploidentical related donor: SFGM-TC recommendations (Part 1)]. / Greffes de cellules souches hématopoïétiques à partir d'un donneur haplo-identique : recommandations de la SFGM-TC (première partie).

Haploidentical allogeneic stem cell transplantation (CST) has globally taken off in the past decade. It appears to be a valid alternative to other sources of stem cells; however, further research is necessary to validate the use of this approach in standard patient care. In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapies (SFGM-TC) set up its fourth annual series of workshops which brought together practitioners from all of its member centers. These workshops took place in September 2013 in Lille. This is part one of the recommendations regarding allogeneic stem cell transplantation from an HLA-haploidentical related donor.

[Medical treatment of renal cell carcinoma]. / Les médicaments du cancer du rein.

AIM: To describe drugs used in renal cell carcinoma. METHOD: Pubmed search for efficacy, mode of action and side effects for each molecule. Additional data were searched from the French regulatory agencies websites (HAS and ANSM). RESULTS: Since 2007, a total of three different therapeutic classes in the management of metastatic renal cell carcinoma are available. These three classes are tyrosine kinase inhibitors with sunitinib and sorafenib, the anti-VEGF antibodies (bevacizumab which is associated with alpha interferon in the treatment of advanced kidney cancer) and mTOR inhibitors with temsirolimus and everolimus. These targeted therapies are a major progress in the treatment of patients with metastatic kidney cancer. The side effects encountered with these molecules are numerous but serious side effects are less than 5% of all reported side effects. CONCLUSIONS: A better understanding of molecular mechanisms has enabled the development of new therapies for the treatment of metastatic renal cell carcinoma. In the future, a personalized approach taking into account the biology of each tumor could be created to provide a more targeted treatment.

[Medical treatment of bladder carcinoma]. / Les médicaments du cancer de vessie.

AIM: To describe drugs used in bladder carcinoma. METHOD: Pubmed search for efficacy, mode of action and side effects for each molecule. Additional data were searched from the French regulatory agencies web sites (HAS and ANSM). RESULTS: The drugs used in the treatment of bladder cancer are represented by the products referred to diagnosis (hexyl aminolevulinate), the intravesical instillations for the treatment of tumors not infiltrating the muscle and the infiltrating tumor chemotherapy (neo-adjuvant treatment or metastatic tumors). The hexyl aminolevulinate cystoscopy allows to identify a significantly greater number of lesions, including carcinoma in situ, compared to conventional white light cystoscopy. For intravesical instillations, BCG has a superior efficacy to mitomycin C with a lower tolerance. The chemotherapies for invasive tumors are effective in metastatic disease in 15-20% of cases with a mean survival of 12 to 14 months. CONCLUSION: Except the use of hexyl aminolevulinate for improving the diagnosis, there was no emergence in recent years of new drugs for the treatment of bladder cancer. Targeted therapies currently available for many neoplasms were ineffective for bladder cancer.

Double reduced-intensity allogeneic hematopoietic stem cell transplantation: a retrospective study from the SFGM-TC.

The purpose of this paper is to describe the outcome of patients who underwent double allogeneic hematopoietic stem cell transplantation (AHSCT) with reduced-intensity conditioning regimens (RIC). Forty-five patients who received double RIC-AHSCT between 1997 and 2006 were retrospectively studied. The predominant diagnosis was acute myeloid leukemia (AML) (n = 17). Other diagnoses were aplasic anemia (AA) (n = 5), myelodysplasic disorder (n = 5), acute lymphoblastic leukemia (ALL) (n = 4), chronic myelomonocytic leukemia (CML) (n = 3), myeloma (n = 3), non-Hodgkin lymphoma (NHL) (n = 3), chronic lymphocytic leukemia (CLL) (n = 2), Hodgkin's disease (HD) (n = 2), and chronic myelomonocytic leukemia (n = 1). Main indications for RIC-AHSCT 2 were relapse (n = 25, 56%) and early (n = 8, 18%) or late (n = 12, 26%) graft failure. Median delays to reach a neutrophil count of 0.5 × 10(9)/L and platelet counts of 50 × 10(9)/L were significantly smaller after the second AHSCT. Among 25 patients who relapsed after RIC-AHSCT 1, 14 patients (56%) presented a response improvement after RIC-AHSCT 2. In this group, 9 patients sustained a complete response and 5 patients a partial response. Moreover, among the 20 patients who had early or late graft failure following RIC-AHSCT 1, 9 (45%) finally reached an engraftment. Disease-free survival (DFS) was significantly improved after RIC-AHSCT 2. Thirteen patients (28%) died of transplant-related mortality (TRM) at a median delay of 69 days (range: 0-451) after RIC-AHSCT 2. Double RIC-AHSCT is a feasible procedure that allows a response or engraftment not observed after RIC-AHSCT 1. The main indication is relapse. However, TRM remains high.

Metastatic angiosarcomas: doxorubicin-based regimens, weekly paclitaxel and metastasectomy significantly improve the outcome.

BACKGROUND: Angiosarcomas are a rare but aggressive form of soft tissue sarcoma. At metastatic stage, the clinical benefit of therapeutic intervention remains debatable. PATIENTS AND METHODS: We have carried a retrospective analysis of 149 cases treated between 1996 and 2009 in the French Sarcoma Group. RESULTS: The median age was 60; the sex ratio was 0.80. Sixty-two percentage of cases presented with metastasis at the diagnosis. About 20% arose in irradiated fields. The median overall survival was 11 months. Treatment consisted in metastasectomy (5.4%), doxorubicin-based regimen (46.9%), weekly paclitaxel (Taxol) (31.5%), other chemotherapy regimens (10.7%) or exclusive palliative care (10.9%). Clinical prognostic factors identified by univariate analysis were presence of bone metastasis (P = 0.0107), presence of other metastasis (P = 0.0327) and performance status (P < 0.0001). The Cox model retained a performance status of two or more as the sole independent prognostic factor (HR [hazard ratio] = 2.49, P < 0.0001). After adjustment to the performance status and compared with exclusive palliative care, the following treatments significantly improve the outcome: doxorubicin-based regimen as first-line chemotherapy (HR = 0.38, P = 0.0165), weekly paclitaxel as first-line regimen (HR = 0.36, P = 0.0146) and metastasectomy (HR = 0.09, P = 0.0221). CONCLUSIONS: This retrospective analysis indicates that some therapeutic interventions may significantly improve the outcome of this aggressive disease. Doxorubicin-based regimens and weekly paclitaxel seem to provide the same range of efficacy.

High-dose chemotherapy consolidation for chemosensitive advanced soft tissue sarcoma patients: an open-label, randomized controlled trial.

BACKGROUND: Metastatic soft tissue sarcoma (STS) prognosis remains poor and few cytotoxic agents offer proven efficacy. This randomized open phase III study examines whether high-dose (HD) chemotherapy with peripheral blood stem cells (PBSCs) could improve overall survival (OS) of chemosensitive patients. PATIENTS AND METHODS: Advanced STS patients aged 18-65 years received four courses of standard mesna, adryamycin, ifosfamide and dacarbazine (MAID) treatment. Chemotherapy-responding patients and patients with at least stable disease amenable to complete surgical resection were randomized to receive standard dose (SD) with two successive MAID cycles or HD treatments of one MAID then MICE intensification: mesna (3.6 g/m(2), day 1-5), ifosfamide (2.5 g/m(2), day 1-4), carboplatin [area under the curve (AUC) 5/day 2-4] and etoposide (300 mg/m(2), day 1-4) with PBSC reinjection at day 7. RESULTS: From 2000 to 2008, 207 patients received four cycles of MAID and 87 assessable patients were randomly assigned to receive the following: 46 SD, 41 HD, with 45 and 38 maintained for analyses after secondary centralized histological review. Futility analyses led to study closure in November 2008. Three-year OS was 49.4% for the SD group versus 32.7% for HD arm, hazard ratio= 1.26, 95% confidence interval 0.70-2.29; progression-free survival was 32.4% and 14.0%, respectively. HD treatment led to higher grades 3-4 toxicity. CONCLUSION: This study failed to show an OS advantage for advanced STS patients treated with dose-intensified chemotherapy with PBSC.

A phase II of gemcitabine combined with pazopanib followed by pazopanib maintenance, as second-line treatment in patients with advanced leiomyosarcomas: A unicancer French Sarcoma Group study (LMS03 study).

BACKGROUND: Options in second-line therapy after doxorubicin-based chemotherapy for metastatic/advanced leiomyosarcoma include gemcitabine (G), trabectedin and pazopanib (P) monotherapy. Currently, no combination therapy is better than monotherapy. LMS03 is an open-label multicentre single-group phase II study designed to assess the efficacy and tolerance of G + P in the second-line setting. PATIENTS AND METHODS: Patients (pts), ECOG ≤2, with metastatic leiomyosarcomas (LMS) after first-line doxorubicin chemotherapy failure were eligible. Pts were treated with G 1000 mg/m2 on days 1 and 8 of each 21 days (maximum eight cycles), in combination with oral daily P (800 mg), until disease progression/toxicity. 9-month progression-free survival (PFS) rate was the primary endpoint. Inacceptable and promising 9-month PFS rates were defined, in the intent-to-treat population, as 32% and 44%. RESULTS: 106 pts were included with a mean age of 59.8 years and an ECOG 0 in 63.5%; the primary tumour site was uterus in 61%. Pts were treated with P + G for a median of 3.8 mo, and P for a median of 4.2 mo. The 9-month PFS rate was 32.1% (95% CI 23.1-41.1). After a median follow-up of 14.2 months, the PFS was 6.5 months (95% CI 5.6-8.2), and the overall survival was 22.4 months (95% CI 16.9-26.5). The best response was 23.8%. The most frequent reported grade 3-4 adverse events were haematological. CONCLUSIONS: LMS03 failed to show that second-line therapy, with gemcitabine combined with pazopanib, followed by pazopanib alone, was beneficial for advanced LMS patients.

[Pulmonary artery intimal sarcoma]. / Sarcome intimal de l'artère pulmonaire.

Pulmonary artery sarcoma is a rare tumor. We present a case of intimal sarcoma arising from right pulmonary artery and left lower pulmonary vein observed in a 44-year-old man with a non-productive cough. Computed tomographic scans and magnetic resonance imaging showing filling defect enhancement contributed early, suggesting the diagnosis of primary vascular tumor, hypothesis confirmed by pathologist findings.

Impact of HLA-G polymorphism on the outcome of allogeneic hematopoietic stem cell transplantation for metastatic renal cell carcinoma.

Renal cell carcinoma (RCC) is particularly sensitive to immune intervention. HLA-G, a non-classical HLA class I molecule with immunomodulatory properties, has been studied with regard to outcome after hematopoietic stem cell transplantation (HSCT), in particular the 14 bp insertion/deletion polymorphism in the 3' untranslated region. Here we analyzed n=56 patients affected by metastatic RCC who received an allogeneic HSCT between 1998 and 2006 in Milano, Marseille, Clermont-Ferrand and Stockholm. The 14 bp polymorphism was analyzed in correlation with overall survival (OS), PFS, acute and chronic GvHD. With a median follow-up of 13 years, a trend towards better outcome was observed when homozygosity for the 14bp-del allele was present: multivariate hazard ratio was 0.50 (95% confidence interval (CI): 0.23-1.13; P=0.10) and 0.57 (95% CI: 0.26-1.26; P=0.17) for OS and PFS, respectively, when 14bp-del/del was compared with 14bp-ins/X. Further exploratory analysis revealed a significant association between T/C at p3003 and improved OS (P=0.05) and PFS (P=0.006) compared with T/T. To our knowledge this is the first study on HLA-G and outcome after HSCT for a solid malignancy. After a coordinated multicenter study, we found that the more tolerogenic polymorphisms (14bp-del/del) is associated with better PFS and OS. The finding on p3003 deserves further investigation.

[French recommendations on control measures to reduce the infectious risk in immunocompromised patients]. / Quelles mesures pour maîtriser le risque infectieux chez les patients immunodéprimés ? Recommandations formalisées d'experts.

The increase use of immunosuppressive treatments in patients with solid cancer and/or inflammatory diseases requires revisiting our practices for the prevention of infectious risk in the care setting. A review of the literature by a multidisciplinary working group at the beginning of 2014 wished to answer the following 4 questions to improve healthcare immunocompromised patients: (I) How can we define immunocompromised patients with high, intermediate and low infectious risk, (II) which air treatment should be recommended for this specific population? (III) What additional precautions should be recommended for immunocompromised patients at risk for infection? (IV) Which global environmental control should be recommended? Based on data from the literature and using the GRADE method, we propose 15 recommendations that could help to reduce the risk of infection in these exposed populations.

Radioimmunotherapy-augmented BEAM chemotherapy vs BEAM alone as the high-dose regimen for autologous stem cell transplantation (ASCT) in relapsed follicular lymphoma (FL): a retrospective study of the EBMT Lymphoma Working Party.

Relapse remains the most common cause of treatment failure in patients receiving autologous stem cell transplantation (ASCT) for follicular lymphoma (FL). The aim of this study was to evaluate the effect of adding radioimmunotherapy or rituximab (R) to BEAM (carmustine, etoposide, ara-c, melphalan) high-dose therapy for ASCT in patients with relapsed FL. Using the European Society for Blood and Marrow Transplantation registry, we conducted a cohort comparison of BEAM (n=1973), Zevalin-BEAM (Z-BEAM) (n=207) and R-BEAM (n=179) and also a matched-cohort analysis of BEAM vs Z-BEAM including 282 and 154 patients, respectively. BEAM, Z-BEAM and R-BEAM groups were well balanced for age, time from diagnosis to ASCT and disease status at ASCT. The cumulative incidences of relapse (IR) at 2 years were 34, 34 and 32% for Z-BEAM, R-BEAM and BEAM, respectively. By multivariate analysis, there were no significant differences with Z-BEAM or R-BEAM compared with BEAM for IR, non-relapse mortality, event-free survival or overall survival. With the caveat that the limitations of registry analyses have to be taken into account, this study does not support adding radioimmunotherapy or R to BEAM in ASCT for relapsed FL. However, we cannot rule out the existence a particular subset of patients who could benefit from Z-BEAM conditioning that cannot be identified in our series, and this should be tested in a randomized trial.
