Sarcomas in patients over 90: Natural history and treatment-A nationwide study over 6 years.

Soft tissue sarcomas (STS) are rare tumors accounting for less than 1% of human cancers. While the highest incidence of sarcomas is observed in elderly, this population is often excluded or poorly represented in clinical trials. The present study reports on clinicopathological presentation, and outcome of sarcoma patients over 90 recorded in the Netsarc.org French national database. NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized multidisciplinary tumor board (MDTB), funded by the French National Cancer Institute to improve the outcome of sarcoma patients. Since 2010, presentation to an MDTB, second pathological review, and collection of sarcoma patient characteristics and follow-up are collected in a database Information of patients registered from January 1, 2010, to December 31, 2016, in NETSARC were collected, analyzed and compared to the younger population. Patients with sarcomas aged >90 have almost exclusively sarcomas with complex genomics (92.0% vs. 66.3%), are less frequently metastatic (5.3% vs. 14·7%) at diagnosis, have more often superficial tumors (39.8% vs. 14.7%), as well as limbs and head and neck sites (75.2% vs. 38.7%) (all p < 0.001). Optimal diagnostic procedures and surgery were less frequently performed in patients over 90 (p < 0.001). These patients were less frequently operated in NETSARC centers, as compared to those of younger age groups including aged 80-90. However, local relapse-free survival, metastatic relapse-free survival and relapse-free survival were not significantly different from those of younger patients, in the whole cohort, as well as in the subgroup of operated patients. As expected overall survival was worse in patients over 90 (p < 0.001). Patients over 90 who were not operated had worse overall survival than younger patients (9.9 vs. 27.3 months, p < 0.001). Patients with STS diagnosed after 90 have distinct clinicopathological features, but comparable relapse-free survival, unless clinical practice guidelines recommendations are not applied. Standard management should be proposed to these patients if oncogeriatric status allows.

Autoimmune hemolytic anemia after nivolumab treatment in Hodgkin lymphoma responsive to immunosuppressive treatment. A case report.

The patients with refractory Hodgkin lymphoma have a poor prognosis. The nivolumab, an IgG4 monoclonal antibody inhibiting the program death 1 pathway has recently demonstrated its efficacy and its safety in patients with heavily pretreated refractory Hodgkin lymphoma. The side effects of this immunotherapy include autoimmune-like syndromes. A 75-year-old woman with no significant comorbidities was treated by nivolumab (3 mg/kg every 2 wk) as a third-line treatment for refractory Hodgkin lymphoma. A clinical response was observed with the first injection of nivolumab, with a reduction in superficial lymph nodes. After the second injection, the patient presented an authentic autoimmune hemolytic anemia with a profound anemia at 64 g/L and biologic characteristics of hemolysis (elevated unconjugated bilirubin, lactate dehydrogenase, and reticulocytes). The direct antiglobulin test was strongly positive for IgG antibodies, and the indirect antiglobulin test became positive with a very high level of autoantibodies. After 2 injections of nivolumab, the patient underwent a fluodeoxyglucose F 18 positron emission tomography-computed tomography, showing a partial response according to modified Cheson criteria. A treatment with prednisone (2 mg/kg), initiated after transfusion of 2 units of red blood cells, permitted the complete resolution of this autoimmune reaction after 3 months of corticotherapy. The fluodeoxyglucose F 18 positron emission tomography-computed tomography performed at the end of the corticotherapy showed a clear disease progression. Considering the very good response achieved after only 2 injections of nivolumab, the limited therapeutic resources for this old woman, and the complete resolution of the autoimmune hemolytic anemia, nivolumab was reintroduced at the same dose, with close clinical and biological monitoring. She received 6 more injections of nivolumab without recurrence of hemolysis.

Lenalidomide versus investigator's choice in relapsed or refractory mantle cell lymphoma (MCL-002; SPRINT): a phase 2, randomised, multicentre trial.

BACKGROUND: Lenalidomide, an immunomodulatory drug with antineoplastic and antiproliferative effects, showed activity in many single-group studies in relapsed or refractory mantle cell lymphoma. The aim of this randomised study was to examine the efficacy and safety of lenalidomide versus best investigator's choice of single-agent therapy in relapsed or refractory mantle cell lymphoma. METHODS: The MCL-002 (SPRINT) study was a randomised, phase 2 study of patients with mantle cell lymphoma aged 18 years or older at 67 clinics and academic centres in 12 countries who relapsed one to three times, had Eastern Cooperative Oncology Group performance status of 0-2, at least one measurable lesion to be eligible, and who were ineligible for intensive chemotherpy or stem-cell transplantation. Using a centralised interactive voice response system, we randomly assigned (2:1) patients in a permuted block size of six to receive lenalidomide (25 mg orally on days 1-21 every 28 days) until progressive disease or intolerability, or single-agent investigator's choice of either rituximab, gemcitabine, fludarabine, chlorambucil, or cytarabine. Randomisation was stratified by time from diagnosis, time from last anti-lymphoma therapy, and previous stem-cell transplantation. Individual treatment assignment between lenalidomide and investigator's choice was open label, but investigators had to register their choice of comparator drug before randomly assigning a patient. Patients who progressed on investigator's choice could cross over to lenalidomide treatment. We present the prespecified primary analysis results in the intention-to-treat population for the primary endpoint of progression-free survival, defined as the time from randomisation to progressive disease or death, whichever occurred first. Patient enrolment is complete, although treatment and collection of additional time-to-event data are ongoing. This study is registered with ClinicalTrials.gov, number NCT00875667. FINDINGS: Between April 30, 2009, and March 7, 2013, we enrolled 254 patients in the intention-to-treat population (170 [67%] were randomly assigned to receive lenalidomide, 84 [33%] to receive investigator's choice monotherapy). Patients had a median age of 68·5 years and received a median of two previous regimens. With a median follow-up of 15·9 months (IQR 7·6-31·7), lenalidomide significantly improved progression-free survival compared with investigator's choice (median 8·7 months [95% CI 5·5-12·1] vs 5·2 months [95% CI 3·7-6·9]) with a hazard ratio of 0·61 (95% CI 0·44-0·84; p=0·004). In the 167 patients in the lenalidomide group and 83 patients in the investigator's choice group who received at least one dose of treatment the most common grade 3-4 adverse events included neutropenia (73 [44%] of 167 vs 28 [34%] of 83) without increased risk of infection, thrombocytopenia (30 [18%] vs 23 [28%]), leucopenia (13 [8%] vs nine [11%]), and anaemia (14 [8%] vs six [7%]). INTERPRETATION: Patients with relapsed or refractory mantle cell lymphoma ineligible for intensive chemotherapy or stem-cell transplantation have longer progression-free survival, with a manageable safety profile when treated with lenalidomide compared with monotherapy investigator's choice options.

Different outcome of T cell acute lymphoblastic leukemia with translocation t(11;14) treated in two consecutive children leukemia group EORTC trials.

Acute lymphoblastic leukemia of T cell lineage (T-ALL) is an aggressive malignant disease which accounts for 15 % of childhood ALL. T(11;14) is the more frequent chromosomal abnormality in childhood T-ALL, but its prognostic value remained controversial. Our aim was to analyze the outcome of childhood T-ALL with t(11;14) to know if the presence of this translocation is associated with a poor prognosis. We conducted a retrospective study from a series of 20 patients with t(11;14), treated in two consecutive trials from the European Organization for Research and Treatment of Cancer Children Leukemia Group over a 19-year period from 1989 to 2008. There were no significant differences between the 2 consecutive groups of patients with t(11;14) regarding the clinical and biological features at diagnosis. Among 19 patients who reached complete remission, 9 patients relapsed. We noticed 7 deaths all relapse- or failure-related. In the 58881 study, a presence of t(11;14) was associated with a poor outcome with an event-free survival at 5 years at 22.2 % versus 65.1 % for the non-t(11;14) T-ALL (p = 0.0004). In the more recent protocol, the outcome of T-ALL with t(11;14) reached that of non-t(11;14) T-ALL with an event-free survival at 5 years at 65.5 versus 74.9 % (p = 0.93). The presence of t(11;14) appeared as a poor prognostic feature in the 58881 trial whereas this abnormality no longer affected the outcome in the 58951 study. This difference is probably explained by the more intensive chemotherapy in the latest trial.

Trabectedin in combination with doxorubicin for first-line treatment of advanced uterine or soft-tissue leiomyosarcoma (LMS-02): a non-randomised, multicentre, phase 2 trial.

BACKGROUND: Metastatic leiomyosarcomas of uterine or soft-tissue origin have poor prognosis and moderate chemosensitivity. Trabectedin has shown activity in pretreated leiomyosarcoma. We did a single-group, multicentre, phase 2 trial (LMS-02) to assess the effect of first-line doxorubicin and trabectedin combination on disease control and survival. METHODS: Adults (18 years to physiological age ≤70 years) with measurable metastatic or unresectable uterine leiomyosarcoma or soft-tissue leiomyosarcoma who had not received any previous chemotherapy were enrolled at 19 centres in France. Treatment consisted of 60 mg/m(2) intravenous doxorubicin followed by 1·1 mg/m(2) trabectedin in a 3 h intravenous infusion on day 1, both by the central venous route, and 6 mg subcutaneous pegfilgrastim on day 2, repeated every 3 weeks for up to six cycles. Surgery for residual disease was permitted. The primary endpoint was the proportion of patients achieving disease control, defined as complete or partial response or stable disease. Stratification was done by anatomical site and analyses were per protocol. This study is registered with ClinicalTrials.gov, number NCT02131480. FINDINGS: Between July 28, 2010, and May 10, 2013, 109 patients were enrolled and treated, of whom 108 were assessable for response: 47 in the uterine leiomyosarcoma group and 61 in the soft-tissue leiomyosarcoma group. 32 (68%) patients in the uterine leiomyosarcoma group and 45 (74%) in the soft-tissue leiomyosarcoma group received all six cycles of treatment. Of 47 patients with uterine leiomyosarcoma, 28 (59·6%, 95% CI 44·3-73·6) achieved a partial response and 13 (27·7%, 15·6-42·6) stable disease; 41 (87·2%, 74·3-95·2) patients achieved disease control. Of 61 patients with soft-tissue leiomyosarcoma, two (3·3%, 95% CI 0·4-11·7) achieved a complete response, 22 (36·1%, 25·0-50·8) had a partial response, and 32 (52·5%, 40·8-67·3) had stable disease; 56 (91·8%, 81·9-97·3) of patients achieved disease control. The most common grade 3-4 treatment-associated adverse events were neutropenia (84 [78%] of 108 patients), increased alanine aminotransferase concentration (42 [39%]), thrombocytopenia (40 [37%]), anaemia (29 [27%]), febrile neutropenia (26 [24%]), and fatigue (21 [19%]). INTERPRETATION: Despite expected but manageable toxic effects, these results support the activity of doxorubicin plus trabectedin as first-line treatment for uterine leiomyosarcoma and soft-tissue leiomyosarcoma. This combination should be developed further in a phase 3 trial against the present standard of care. FUNDING: Pharmamar and Amgen.

Off-label use of targeted therapies in osteosarcomas: data from the French registry OUTC'S (Observatoire de l'Utilisation des Thérapies Ciblées dans les Sarcomes).

BACKGROUND: The objective of this study is to explore the off-label use of targeted therapies (TTs) for patients with osteosarcoma registered within the French Sarcoma Group--Bone Tumor Study Group (GSF-GETO) national registry. METHODS: All patients with an osteosarcoma, registered between January 1, 2009 and July 15, 2013 were analyzed. RESULTS: Twenty-nine patients with refractory relapsed osteosarcomas received 33 treatment lines of TTs. The median age at the beginning of treatment was 19 years (range 9-72). The median number of previous lines of chemotherapy was 3 (range 1-8). Before inclusion, 3 patients were in second complete remission, 26 were in progression for metastatic relapse. Twenty-three patients received sirolimus (in combination with cyclophosphamide for 18); 5, sunitinib; 4, sorafenib; and one, pazopanib. Stable disease was observed for 45.5% of patients (95% Confidence Interval (CI) [20-52.8]). The median Progression-Free Survival (PFS) was 3 months (95% CI [2-5.4]) for patients treated by sirolimus and 1.8 months (95% CI [1.3-2.8]) for patients receiving multi-targeted tyrosine kinase inhibitors; 6-month PFS 15%. The median Overall Survival (OS) was 6.8 months (95% CI [4.7-12.1]), and one-year OS was 24%. In a multivariate analysis, PFS was superior for patients receiving sirolimus compared to other TTs (Hazard Ratio (HR) = 2.7, 95% CI [1.05-7.1]). No toxic death was reported. Grade 3 and 4 toxicities were observed in 27 and 6% of cases respectively. CONCLUSION: Off-label TTs, especially sirolimus, reported benefit in the treatment of refractory osteosarcomas with an acceptable toxicity profile, including in pediatric population.

The off-label use of targeted therapies in sarcomas: the OUTC'S program.

BACKGROUND: Few targeted therapies (TTs) are registered for sarcoma treatment despite numerous phase II studies and yet there are potential treatment options for patients after standard treatment escape. The French Sarcoma Group - Bone Tumor Study Group (GSF-GETO) created a national registry to evaluate the outcome of patients treated with off-label TTs. METHODS: Every consecutive sarcoma-patient receiving an off-label TT outside a clinical trial was included. The objective was to describe this patient efficacy and safety data in routine practice. RESULTS: From October 2008 to October 2011, 249 patients in 24 centers received 278 treatment lines with TTs. Twenty-five histological subtypes were included: most frequent were leiomyosarcoma (n=48, receiving sorafenib in 63%, and sunitinib in 27%), GIST (n=39, receiving sorafenib in 79%), and angiosarcoma (n=18, receiving sorafenib in 78%). The overall response rate to TTs was 15% (95% CI [10,6-20,2]), the disease control rate at 2 months was 59%. The median progression-free survival was 4,1 months (IC 95% [3,2-4,8]). Three complete responses were observed. No toxic death occurred, grade 3 and 4 toxicities were reported in 74 (27%) and 14 patients (5%) respectively. CONCLUSION: Off-label TTs can be used for sarcoma patients in routine practice with an acceptable toxicity profile and efficacy similar to that reported in non-randomized clinical trials.

Dose-dense rituximab-CHOP compared with standard rituximab-CHOP in elderly patients with diffuse large B-cell lymphoma (the LNH03-6B study): a randomised phase 3 trial.

BACKGROUND: Immunochemotherapy with rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) has become the standard of care for elderly patients with diffuse large B-cell lymphoma. We aimed to ascertain if a dose-dense R-CHOP regimen administered every 2 weeks (R-CHOP14) was superior to the standard 3-week schedule (R-CHOP21). METHODS: We did a randomised phase 3 trial at 83 centres in four countries. 602 patients aged 60-80 years with untreated diffuse large B-cell lymphoma and at least one adverse prognostic factor (age-adjusted international prognostic index ≥ 1) were eligible for the study. We randomly allocated individuals to R-CHOP-ie, rituximab (375 mg/m(2)), cyclophosphamide (750 mg/m(2)), doxorubicin (50 mg/m(2)), vincristine (1.4 mg/m(2), up to 2 mg) all on day 1, and prednisone 40 mg/m(2) daily for 5 days-administered every 14 days (n=304) or every 21 days (n=298) for eight cycles. We did permuted-block randomisation (block size four, allocation ratio 1:1) stratified by centre and number of adverse prognostic factors. The primary endpoint was event-free survival. Our analysis was of the intention-to-treat population, and we present the final analysis. This study is registered with ClinicalTrials.gov, number NCT00144755. FINDINGS: Two patients allocated R-CHOP21 were ineligible for the study and were excluded from analyses. After median follow-up of 56 months (IQR 27-60), 3-year event-free survival was 56% (95% CI 50-62) in the R-CHOP14 group and 60% (55-66) in the R-CHOP21 group (hazard ratio 1.04, 95% CI 0.82-1.31; p=0.7614). Grade 3-4 neutropenia occurred in 224 (74%) of 304 patients allocated R-CHOP14 and 189 (64%) of 296 assigned R-CHOP21, despite increased use of granulocyte colony-stimulating factor in the R-CHOP14 group compared with the R-CHOP21 group. 143 (47%) patients in the R-CHOP14 group received at least one red-blood-cell transfusion versus 93 (31%) in the R-CHOP21 group (p=0.0001). 35 (12%) patients allocated R-CHOP14 received at least one platelet transfusion versus 25 (8%) assigned R-CHOP21 (p=0.2156). 155 (51%) patients who were assigned R-CHOP14 had at least one serious adverse event compared with 140 (47%) who were allocated R-CHOP21. INTERPRETATION: In elderly patients with untreated diffuse large B-cell lymphoma and at least one adverse prognostic factor, a 2-week dose-dense R-CHOP regimen did not improve efficacy compared with the 3-week standard schedule. The frequency of toxic side-effects was similar between regimens, but R-CHOP14 was associated with increased need for red-blood-cell transfusion.

Long term survival in adult osteosarcoma patients treated with a two-drug regimen: Final results of the OSAD93 phase II study of the FSG-GETO.

RATIONALE: We report a phase II trial (OSAD93) testing CDDP with ifosfamide (IFO), without doxorubicin in neoadjuvant phase, in adult osteosarcoma with a 25 years follow-up. PATIENTS AND METHODS: This is a multicentric phase II study of neoadjuvant chemotherapy with IFO and CDDP in localized high-grade osteosarcoma of patients. Patients received 4 pre-operative courses of IFO 9 g/m2 and CDDP 100 mg/m2 on day 4 (SHOC regimen), followed by local treatment. Doxorubicin was added post-operatively (HOCA regimen) in patients with > 10 % residual tumor cells. A Good Histological Response (GHR), ie ≤ 10 % residual tumor cells in > 30 % of patients, was the primary objective. Disease-free survival (DFS), overall survival (OS) and toxicity were secondary objectives. RESULTS: From Jan 1994 to Jun 1998, 60 patients were included. Median age was 27 (range: 16-63). Primary tumor sites were limbs (76 %), trunk, head or neck (24 %). After neoadjuvant SHOC, grade 3-4 and febrile neutropenia, thrombopenia, and re-hospitalization occurred in 58 %, 17 %, 17 % and 22 % of SHOC courses and in 76 %, 28 %, 47 %, 47 % of HOCA courses, respectively. GHR was obtained in 16/60 (27.5 %) patients. With a median follow-up of 322 months, the DFS and OS were 51.8 % and 64.4 % at 5 years. At 10 years, DFS and OS were 49.9 % and 64.4 %. At 25 years, DFS and OS were 47.8 % and 55.9 %. No long-term cardiac toxicity was observed. Three patients developed a second malignancy (one fatal) after 300 months. CONCLUSION: Though the primary endpoint of OSAD93 was not met, this pre-operative doxorubicin-free regimen led to excellent long-term survival with limited toxicity in localized osteosarcoma.

Major efficacy of trabectedin in 2 metastatic osteosarcoma patients with wild-type Asp1104 ERCC5 tumor status.

BACKGROUND: Treatment of osteosarcoma of the extremities consists of surgical resection preceded and followed by chemotherapy, including high-dose methotrexate or adriamycin-based protocols. When distant relapse occurs, therapeutic options are scarce. Trabectedin, a DNA-binding agent, is indicated for the treatment of patients with advanced soft tissue sarcomas after failure of anthracyclines and ifosfamide. In this indication, the 6-month progression-free survival is about 35-40%. Recent reports showed that some specific single nucleotide polymorphisms (SNPs) from DNA repair genes could be associated with sensitivity to trabectedin in soft tissue sarcomas. CASE REPORTS: We report our experience of 2 metastatic, heavily pre-treated osteosarcoma patients who were treated with trabectedin. Pyrosequencing analyses of tumors from both patients for several SNPs of the ERCC1, ERCC5 and BRAC1 genes were performed. Both patients showed major response to trabectedin, which was interestingly related with homozygoty of the common guanine allele of ERCC5 (G/G genotype; Asp/Asp) after pyrosenquencing analysis of tumors from both patients. This polymorphism was previously shown to be associated with better outcome in soft tissue sarcoma patients treated with trabectedin. CONCLUSION: Homozygoty for the wild-type Asp1104 SNP of the ERCC5 gene was found in 2 cases of relapsed osteosarcoma, who responded to trabectedin.

Treatment decisions for elderly patients with haematological malignancies: a dilemma.

Over the past decade, haematological malignant diseases have been diagnosed with increasing frequency in patients older than 65 years. The management of these diseases is particularly difficult in elderly patients, as non-tumour-related life expectancy is highly variable and the benefit-to-risk ratio for oncological treatments depends on comorbidities and pharmacological factors. Very few data are available in very old or frail patients, and management decisions are usually based on data obtained in younger patients. Patients might, therefore, be overtreated or undertreated without clear clinical or biological justification. In this Review we discuss the management of haematological malignant diseases in the elderly, with respect to biology or pharmacokinetic and pharmacodynamic features. We focus on acute myeloid leukaemia and aggressive lymphoma. Additionally, we discuss how the implementation of geriatric tools, such as comprehensive geriatric assessment scores, in the clinical management of elderly patients might help to adapt treatment to meet individual patients' needs.

Value of infliximab (Remicade®) in patients with low-risk myelodysplastic syndrome: final results of a randomized phase II trial (EORTC trial 06023) of the EORTC Leukemia Group.

Tumor-necrosis factor alpha activity has been correlated to ineffective erythropoiesis in lower risk myelodysplastic syndromes. Infliximab (Remicade(®)) is an anti-tumor necrosis factor alpha chimeric antibody that is used in the treatment of patients with rheumatoid arthritis or Crohn's disease. Forty-six patients with myelodysplastic syndromes and a relatively low risk of developing acute leukemia were included in a randomized phase II study assessing the therapeutic activity of two dosages of infliximab administration (3 mg/kg vs. 5 mg/kg). The primary end point was the response rate. Responses were observed in 3 of 22 patients (13.1%) randomized to the 3 mg/kg arm, versus 0 of 21 patients randomized in the 5 mg/kg arm. According to the statistical design of the current study, neither of the two infliximab dose schedules tested showed sufficient activity as a single agent in this cohort of unselected patients with early myelodysplastic syndrome.

Attenuated immunochemotherapy regimen (R-miniCHOP) in elderly patients older than 80 years with diffuse large B-cell lymphoma: a multicentre, single-arm, phase 2 trial.

BACKGROUND: Diffuse large B-cell lymphoma is a common cancer in elderly patients. Although treatment has been standardised in younger patients, no prospective study has been done in patients over 80 years old. We aimed to investigate the efficacy and safety of a decreased dose of CHOP (doxorubicin, cyclophosphamide, vincristine, and prednisone) chemotherapy with a conventional dose of rituximab in elderly patients with diffuse large B-cell lymphoma. METHODS: We did a prospective, multicentre, single-arm, phase 2 study of patients aged over 80 years who had diffuse large B-cell lymphoma. Patients were included from 38 centres in France and Belgium. All patients received six cycles of rituximab combined with low-dose CHOP (R-miniCHOP) at 3-week intervals. Patients received 375 mg/m(2) rituximab, 400 mg/m(2) cyclophosphamide, 25 mg/m(2) doxorubicin, and 1 mg vincristine on day 1 of each cycle, and 40 mg/m(2) prednisone on days 1-5. The primary endpoint was overall survival, both unadjusted and adjusted for treatment and baseline prognostic factors. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, NCT01087424. FINDINGS: 150 patients were enrolled between Jan 9, 2006, and Jan 23, 2009 and 149 were included in the intention-to-treat analyses. Median age was 83 years (range 80-95). After a median follow-up of 20 months (range 0-45), the median overall survival was 29 months (95% CI 21 to upper limit not reached); 2-year overall survival was 59% (49-67%). In multivariate analyses, overall survival was only affected by a serum albumin concentration of 35 g/L or less (hazard ratio 3·2, 95% CI 1·4-7·1; p=0·0053). Median progression-free survival was 21 months (95% CI 13 to upper limit not reached), with a 2-year progression free survival of 47% (38-56). 58 deaths were reported, 33 of which were secondary to lymphoma progression. 12 deaths were attributed to toxicity of the treatment. The most frequent side-effect was haematological toxicity (grade ≥3 neutropenia in 59 patients; febrile neutropenia in 11 patients). INTERPRETATION: R-miniCHOP offers a good compromise between efficacy and safety in patients aged over 80 years old. R-miniCHOP should be considered as the new standard treatment in this subgroup of patients. FUNDING: Groupe d'Etude des Lymphomes de l'Adulte (GELA).

High-dose therapy followed by autologous purged stem cell transplantation and doxorubicin-based chemotherapy in patients with advanced follicular lymphoma: a randomized multicenter study by the GOELAMS with final results after a median follow-up of 9 years.

Autologous stem cell transplantation (ASCT) as first-line therapy for follicular lymphoma (FL) remains controversial. The multicenter study randomized 172 patients with untreated FL for either immunochemotherapy or high-dose therapy (HDT) followed by purged ASCT. Conditioning was performed with total body irradiation (TBI) and cyclophosphamide. The 9-year overall survival (OS) was similar in the HDT and conventional chemotherapy groups (76% and 80%, respectively). The 9-year progression-free survival (PFS) was higher in the ASCT than the chemotherapy group (64% vs 39%; P = .004). A PFS plateau was observed in the HDT group after 7 years. On multivariate analysis, OS and PFS were independently affected by the per-formance status score, the number of nodal areas involved, and the treatment group. Secondary malignancies were more frequent in the HDT than in the chemotherapy group (6 secondary myelodysplastic syndrome/acute myeloid leukemia and 6 second solid tumor cancers vs 1 acute myeloid leukemia, P = .01). The occurrence of a PFS plateau suggests that a subgroup of patients might have their FL cured by ASCT. However, the increased rate of secondary malignancies may discourage the use of purged ASCT in combination with TBI as first-line treatment for FL. This trial has been registered with ClinicalTrials.gov under identifier NCT00696735.

Signalling and chemosensitivity assays in melanoma: is mutated status a prerequisite for targeted therapy?

Selection for targeted therapies in melanoma is currently based on the search for mutations in selected genes. We aimed at evaluating the interest of signalling and chemosensitivity studies in addition to genotyping for assessing the best suitable treatment in an individual patient. We extracted genomic DNA and melanoma cells from tumor tissue of a skin metastasis of a 17-year-old woman with stage IV melanoma progressing despite three successive lines of treatment. Despite the absence of mutation in BRAF, NRAS cKIT, the MAPK pathway was activated and a significant response to sorafenib, a mitogen-activated protein kinase (MAPK)/RAF inhibitor, was found in signalling and chemosensitivity assays. A treatment combining sorafenib and dacarbazine produced a partial response for 9 months, with marked necrosis in some lesions. Chemosensitivity assays and signalling pathway studies could be of great value in addition to genotyping for assessing the most appropriate treatment in melanoma.

Clinical characteristics and outcome of isolated extracerebral relapses of primary central nervous system lymphoma: a case series.

There is very limited data on isolated systemic relapses of primary central nervous system lymphomas (PCNSL). We retrospectively reviewed the clinical characteristics and outcome of 10 patients with isolated systemic disease among 209 patients with PCNSL mainly treated with methotrexate-based chemotherapy (CT) with or without radiation therapy (RT). Isolated systemic relapse remained rare (4.8%, 10/209 patients). Median time from initial diagnosis to relapse was 33 months (range, 3-94). Sites of relapse were mostly extranodal. Three patients presented with early extra-cerebral (EC) relapse 3, 5 and 8 months from the beginning of initial treatment, respectively, and 7 patients had later relapses (range, 17-94 months). Treatment at relapse included surgery alone, RT alone, CT with or without radiotherapy, or CT with autologous stem cell transplantation (ASCT). Median overall survival (OS) after relapse was 15.5 months (range, 5.8-24.5) compared to 4.6 months (range, 3.6-6.5) for patients with central nervous system (CNS) relapse (p = 0.35). In conclusion, isolated systemic relapses exist but are infrequent. Early EC relapse suggests the presence of systemic disease undetectable by conventional evaluation at initial diagnosis. Patient follow-up must be prolonged because systemic relapse can occur as late as 10 years after initial diagnosis. Whether EC relapses of PCNSL have a better prognosis than CNS relapses needs to be assessed in a larger cohort.

Upfront VIP-reinforced-ABVD (VIP-rABVD) is not superior to CHOP/21 in newly diagnosed peripheral T cell lymphoma. Results of the randomized phase III trial GOELAMS-LTP95.

Peripheral T-Cell lymphomas (PTCL) are relatively rare diseases but appear to be highly aggressive and display worse remission and survival rates than B-cell lymphomas. Despite unsatisfactory results with the cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) regimen, it remains the reference front-line therapy in these diseases, but has not been challenged in phase III trials. The Groupe Ouest Est d'Etude des Leucémies et Autres Maladies du Sang (GOELAMS) devised an alternative therapeutic schedule including etoposide, ifosfamide, cisplatin alternating with doxorubicin, bleomycin, vinblastine, dacarbazine (VIP-reinforced-ABVD; VIP-rABVD) and compared it to CHOP/21 as front-line treatment in non-cutaneous PTCL. All newly diagnosed patients were eligible. The primary objective was to improve the 2-year event-free survival (EFS) rate. Secondary objectives were to compare the response rate, overall survival, and toxicities as well as identify prognostic factors. Eighty-eight patients were identified between 1996 and 2002. Both arms were well balanced for patients' characteristics in terms of histological and clinical presentation. No significant difference was observed between the two arms in terms of 2-year EFS. Anaplastic large cell lymphoma type and Ann Arbor stage I-II were identified as two independent favourable prognostic factors influencing survival. VIP-rABVD was not superior to CHOP/21 in terms of EFS as first-line treatment of PTCL, confirming that CHOP/21 remains the reference regimen in these lymphomas.

Optimizing the treatment of liver metastases from uveal melanomas with transarterial chemoembolization using melphalan and calibrated microspheres.

INTRODUCTION: Patients with liver metastasis from uveal melanoma have a poor prognosis. Efficacy and safety of hepatic transarterial chemoembolization (TACE) using melphalan and microspheres was evaluated. MATERIALS AND METHODS: Monocentric retrospective study of all consecutive patients treated by TACE using melphalan and 250µm calibrated microspheres between 2004 and 2016. Radiological response was assessed according to RECIST 1.1, modified (m)-RECIST and EASL on contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI). The primary endpoint was overall survival (OS). Liver metastasis response, hepatic, extrahepatic and global progression free survival (PFS) complications were evaluated with the common terminology criteria for adverse events version 4.0 (CTCAE 4.0) and survival factors were secondary endpoints. RESULTS: Thirty-four patients underwent 138 TACE (4; 4.1 sessions; range 1-9). Median OS was 16.5 months (mean 21.6 months). Liver metastasis response combining partial and complete response was 42.4%, 97%, 97% with RECIST 1.1, mRECIST, EASL, respectively. There were 58 severe (CTCAE≥3) but manageable complications in 28 patients, except for 1 toxic death. CONCLUSION: For patients with liver metastases from uveal melanoma ineligible for local treatments, TACE using melphalan may be performed as first line therapy in metastatic miliary disease from uveal melanomas with careful supportive care.

Phase III trial of standard versus dose-intensified doxorubicin, ifosfamide and dacarbazine (MAID) in the first-line treatment of metastatic and locally advanced soft tissue sarcoma.

Multidrug chemotherapy increases responses in advanced soft tissues sarcoma. Can a 20% increase of relative dose intensity of the MAID regimen, more improve responses? From 1994 to 1997, 162 patients were randomized in a phase III study to the conventional drug combination (6 cycles of MAID: 60, 7,500, 900 mg/m(2) for doxorubicin, ifosfamide and dacarbazine respectively), or at doses 20-33% higher per cycle (5 cycles of intensified MAID for similar cumulative doses) with systematic G-CSF. Primary endpoint was response rate; secondary were toxicity, event-free and overall survival. The objective response rate in assessable patients was 38% with intensified MAID and 35% with MAID (p = 0.72). Event-free and overall survivals were similar in both arms. Only grade 3-4 thrombocytopenia and anemia were significantly higher in intensified arm. Treatment with intensified MAID did not improve response rate neither survival and cannot be recommended for advanced or metastatic soft tissue sarcoma.

Primitive neuroectodermal tumor of the pelvis in an elderly patient.

BACKGROUND: Peripheral primitive neuroectodermal tumors (PNET) belong to the rare family of primary bone neoplasms. Recent clinicopathological studies have revealed that Ewing's sarcoma and PNET have overlapping features and they are now included in the same classification, the Ewing's sarcoma family of tumors (EFTs). PNET have a marked predilection for the extremities and are very rare in the pelvis. These tumors can occur at any age with a peak of incidence in the second and third decades but are very rare in patients over 40 years. CASE REPORT: We report the case of a 69-year-old man with PNET sarcoma. Outcome was favorable after combined modality treatment including chemotherapy based on the Memphis protocol - adapted from that used for Ewing's sarcoma in children - and surgery. CONCLUSION: Our case is uncommon because of the age at diagnosis, the fortuitous way of revelation, and the choice of dose-intense chemotherapy adapted from the Memphis protocol (cyclophosphamide- and doxorubicin-based) for children, which was efficient and safe. It supports the fact that an adult, and even an old patient, with good physical status, may be treated safely and radically even with dose-adapted aggressive chemotherapy.
