ABSTRACT
Between 2011 and 2012, a phase II trial evaluated the use of the RiBVD (Rituximab, Bendamustine, Velcade and Dexamethasone) combination as first-line treatment for mantle cell lymphoma (MCL) patients aged over 65. We have now re-examined the classic prognostic factors, adding an assessment of the mutation status of TP53. Patients (n=74; median age 73 years) were treated with the RiBVD combination. Median Progression Free Survival (mPFS) was 79 months, and median Overall Survival (mOS) was 111 months. TP53 mutation status was available for 54/74 (73%) patients. TP53 mutations (TP53mt) were found in 12 patients (22.2%). In multivariate analysis, among the prognostic factors (PF) evaluated, only TP53mt and an albumin level below 3.6 g/dL (Alb<3.6 g/dL) were independently associated with a shorter mPFS. A hazard ratio (HR) of 3.16 (1.3-9.9, p=0.014) was obtained for TP53mt versus TP53wt, and 3.6 (1.39-9.5, p=0.009) for Alb<3.6 g/dL vs Alb≥3.6 g/dL. In terms of mOS, multivariate analysis identified three PFs: TP53mt (HR: 5.9 (1.77-19.5, p=0.004)), Alb<3.6 g/dL (HR: 5.2 (1.46-18.5, p=0.011)), and ECOG=2 (HR: 3.7 (1.31-10.6, p=0.014)). Finally, a score combining TP53 status and albumin level distinguished three populations based on the presence of 0, 1, or 2 PF. For these populations, mPFS was 7.8 years, 28 months and 2.5 months, respectively. Our prolonged follow-up confirmed the efficacy of the RiBVD regimen, comparing it favorably to other regimens. TP53mt and hypoalbuminemia emerge as strong PF that can be easily integrated into prognostic scores for older adult patients with MCL.
ABSTRACT
The treatment of primary vitreoretinal lymphoma (PVRL) remains controversial regarding the use of local, systemic, or combined treatments. The aim of this study was to analyze the efficacy and toxicity of intravenous high-dose methotrexate (IV HD-MTX) based systemic therapy in a uniformly treated population of PVRL patients. From a nationwide French database, we retrospectively selected 59 patients (median age: 70 years, median Karnofsky Performance Status: 90%) with isolated PVRL at diagnosis who received first-line treatment with HD-MTX between 2011 and 2018. 8/59 patients also received a local treatment. No deaths or premature discontinuations of MTX due to toxicity were reported. A complete response was obtained in 40/57 patients after chemotherapy. Before treatment, IL-10 was elevated in the aqueous humor (AH) or in the vitreous in 89% of patients. After treatment, AH IL-10 was undetectable in 87% of patients with a CR/uCR/PR and detectable in 92% of patients with PD/SD. After a median follow-up of 61 months, 42/59 (71%) patients had relapsed, including 29 isolated ocular relapses as the first relapse and a total of 22 brain relapses. The median overall survival, progression-free survival, ocular-free survival and brain-free survival were 75, 18, 29 and 73 months, respectively. IV HD-MTX based systemic therapy as a first-line treatment for isolated PVRL is feasible, with acceptable toxicity, even in an elderly population. This strategy seems efficient to prevent brain relapse with prolonged overall survival. However, the ocular relapse rate remains high. New approaches are needed to improve local control of this disease, and ocular assessment could be completed by monitoring AH IL-10.

The benefit of radiotherapy (RT) after chemotherapy in limited-stage diffuse large B-cell lymphoma (DLBCL) remains controversial. We conducted a randomized trial in patients with nonbulky limited-stage DLBCL to evaluate the benefit of RT after rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Patients were stratified according to the modified International Prognostic Index, including lactate dehydrogenase, Eastern Cooperative Oncology Group performance status, age, and disease stage. The patients received 4 or 6 consecutive cycles of R-CHOP delivered once every 2 weeks, followed or not by RT at 40 Gy delivered 4 weeks after the last R-CHOP cycle. All patients were evaluated by fluorodeoxyglucose-positron emission tomography scans performed at baseline, after 4 cycles of R-CHOP, and at the end of treatment. The primary objective of the trial was event-free survival (EFS) from randomization. The trial randomly assigned 165 patients in the R-CHOP arm and 169 in the R-CHOP plus RT arm. In an intent-to-treat analysis with a median follow-up of 64 months, 5-year EFS was not statistically significantly different between the 2 arms, with 89% ± 2.9% in the R-CHOP arm vs 92% ± 2.4% in the R-CHOP plus RT arm (hazard ratio, 0.61; 95% confidence interval [CI], 0.3-1.2; P = .18). Overall survival was also not different at 92% (95% CI, 89.5%-94.5%) for patients assigned to R-CHOP alone and 96% (95% CI, 94.3%-97.7%) for those assigned to R-CHOP plus RT (P = not significant). R-CHOP alone is not inferior to R-CHOP followed by RT in patients with nonbulky limited-stage DLBCL. This trial was registered at www.clinicaltrials.gov as #NCT00841945.

BACKGROUND: The R-DHAP regimen (rituximab, cisplatin, dexamethasone, and high-dose cytarabine) is standardly used to treat relapsed Non-Hodgkin lymphoma (NHL). Despite scarce data, cisplatin is frequently substituted with oxaliplatin (R-DHAOx) to avoid nephrotoxicity. We compared nephrotoxicity of cisplatin and oxaliplatin based on creatinine-based trajectory modeling. METHODS: All patients with NHL treated by R-DHAP or R-DHAOx in Angers hospital between January 01, 2007, and December 31, 2014, were included. Patients received cisplatin 100 mg/m2 or oxaliplatin 130 mg/m2 (d1) with cytarabine (2000 mg/m2 , two doses, d2), dexamethasone (40 mg, d1-4), and rituximab (375 mg/m2 , d1). Creatinine levels were recorded before each cycle. Individual profiles of trajectories were clustered to detect homogeneous patterns of evolution. RESULTS: Twenty-two patients received R-DHAP, 35 R-DHAOx, 6 switched from R-DHAP to R-DHAOx due to nephrotoxicity. Characteristics of patients were similar between two groups. Patients receiving R-DHAP experienced more severe renal injury than patients receiving R-DHAOx (68% vs. 7.7%, P < .001). Two homogeneous clusters appeared: cluster A, with a majority of R-DHAOx (32, 91.4%), was less nephrotoxic than B, with a majority of R-DHAP (19, 86.4%), with a decreased average serum creatinine level (P < .0001). There were no other differences between clusters. CONCLUSIONS: Our study confirms that R-DHAOx regimen causes less nephrotoxicity than R-DHAP regimen.

We present results of a prospective, multicenter, phase II study evaluating rituximab, bendamustine, bortezomib and dexamethasone as first-line treatment for patients with mantle cell lymphoma aged 65 years or older. A total of 74 patients were enrolled (median age, 73 years). Patients received a maximum of six cycles of treatment at 28-day intervals. The primary objective was to achieve an 18-month progression-free survival rate of 65% or higher. Secondary objectives were to evaluate toxicity and the prognostic impact of mantle cell lymphoma prognostic index, Ki67 expression, [18F]fluorodeoxyglucose-positron emission tomography and molecular minimal residual disease, in peripheral blood or bone marrow. With a median follow-up of 52 months, the 24-month progression-free survival rate was 70%, hence the primary objective was reached. After six cycles of treatment, 91% (54/59) of responding patients were analyzed for peripheral blood residual disease and 87% of these (47/54) were negative. Four-year overall survival rates of the patients who did not have or had detectable molecular residual disease in the blood at completion of treatment were 86.6% and 28.6%, respectively (P<0.0001). Neither the mantle cell lymphoma index, nor fluorodeoxyglucose-positron emission tomography nor Ki67 positivity (cut off of ≥30%) showed a prognostic impact for survival. Hematologic grade 3-4 toxicities were mainly neutropenia (51%), thrombocytopenia (35%) and lymphopenia (65%). Grade 3-4 non-hematologic toxicities were mainly fatigue (18.5%), neuropathy (15%) and infections. In conclusion, the tested treatment regimen is active as frontline therapy in older patients with mantle cell lymphoma, with manageable toxicity. Minimal residual disease status after induction could serve as an early predictor of survival in mantle cell lymphoma. ClinicalTrials.gov: NCT 01457144.

Autologous stem cell transplantation (ASCT) is considered as an attractive treatment option for young mantle cell lymphoma (MCL) patients. This retrospective SFGM-TC study analyzed the outcome of 500 MCL patients treated with ASCT and investigated parameters that may modify the outcome of patients who proceeded to ASCT upfront (n = 396). For all patients, median age at ASCT was 56 years (range, 26-71). Median follow-up was 34 months. Three-year progression free survival (PFS) and overall survival (OS) were 63.5 % [95 % CI, 58.7-68.6 %] and 79.5 % [95 % CI, 75.3-83.4 %], respectively. Median time from ASCT to relapse was 22 months (range, 0-136 m). For patients transplanted upfront and in multivariate analysis, age (HR = 2 [1.2-3.4], p = .01, and HR = 2.3 [1.2-4.5], p = .01), disease status at time of ASCT (HR = 1.7 [1.1-2.6], p = .01 and HR = 1.8 [1.1-3.1], p = .03), and use of rituximab (HR = 0.5 [0.3-0.8], p = .002 and HR = 0.5 [0.3-0.9], p = .01) were statistically predictive for both PFS and OS. Also, first line treatment including anthracycline and high-dose cytarabine followed by ASCT conditioned with TAM improved PFS. To conclude, this study suggests that ASCT in MCL can provide a high response rate but may not be sufficient to cure MCL even when ASCT is performed upfront, highlighting the need for innovative approaches before ASCT, aiming to increase complete response rate, and after ASCT, to maintain response.

In recent decades, follow-up of cancer survivors has taken on its full meaning with the gradual improvement in the survival of children and adolescents with cancer. This follow-up is associated specially for adolescents with a multitude of transitions: the transition from therapeutic management to the monitoring for possible relapse, the transition into long-term follow-up after childhood cancer, the transition from a pediatric system to an adult care system. If this transition can be perceived as difficult by patients, it gives young people the opportunity to access more autonomous follow-up and support in becoming an adult. Supporting the transition should make caregivers attentive to this time of consolidation of adolescence, favorable to the emergence of a sense of stable, mature identity that guarantees a certain autonomy. This is a key to a successful transition limiting breakdown of care and promoting "the work of the disease". The double contribution of adult and pediatric oncology provides support tailored to these psychic and societal issues. AYA teams can actively participate in this process by facilitating the acculturation of pediatric and adult care teams to the specificity of this group, thus allowing a continuum of care.

AIMS: To evaluate the feasibility of the histopathological diagnosis of prefibrotic-early primary myelofibrosis (PM) as described in the World Health Organization (WHO) classification and to evaluate the clinical implications of prefibrotic-early PM in a series of patients previously diagnosed as having essential thrombocythemia (ET) according to the Polycythemia Vera Study Group criteria. METHODS AND RESULTS: WHO criteria were applied to bone marrow biopsy specimens by two pathologists who then reclassified 127 cases as 102 ET (80.3%), 18 prefibrotic-early PM (14.2%) and seven fibrotic PM (5.5%). In 45 cases (35%), the final diagnosis was only reached by consensus. The megakaryocytic criteria that best discriminated between ET and prefibrotic-early PM were an increased nucleo-cytoplasmic ratio, presence of cloudlike nuclei, hyperchromatic-dysplastic nuclei, paratrabecular megakaryocytes and tight clusters. A histological score discriminated between ET (score < or =3) and PM (score > or =6), but 21 cases showed an intermediate ambiguous score. No significant differences were observed at diagnosis and at follow-up (median time 93 months) for thrombosis, major haemorrhage, laboratory data, transformation into overt myeloid metaplasia and survival. CONCLUSIONS: The distinction between ET and prefibrotic-early PM is impaired by subjectivity in pathological practice and is of questionable clinical relevance, at least when considering individual patients.

UNLABELLED: Background There is currently no international consensus for first-line treatment (prior to autologous stem cell transplantation) in mantle cell lymphoma patients. Here, we investigated the efficacy and tolerance of VAD associated with chlorambucil (VAD+C) and rituximab or not before autologous stem cell transplantation. DESIGN AND METHODS: Between 1996 and 2005, 113 previously untreated mantle cell lymphoma patients were enrolled in two consecutive prospective phase II studies. Responses and response factors to the (R)VAD+C regimen were evaluated. The survival prognostic value of the MIPI score and Ki67 were also analyzed. RESULTS: The induction phase of 4 courses of (R)VAD+C showed very low hematologic and extra-hematologic toxicity (grade 3-4 thrombopenia and neutropenia, 9% and 2.7%, respectively and grade 3-4 extra-hematologic toxicities, 1.6%). Overall and complete response rates were 73% and 46%, respectively, and rose to 83% and 51% for the 70% of patients with less than two independent response factors (LDH, B symptoms and lymphocytosis). At the end of treatment, 65% of patients were in complete remission. Progression free and overall survival were significantly better in the transplanted population. The MIPI score was confirmed as a predictor of survival. Ki67, serum LDH, Performance Status (PS) and B symptoms were identified as independent prognostic factors of survival. A prognostic scoring system could stratify patients into three risk groups with markedly different median overall survival of 112, 44 and 11 months, respectively. Conclusions The (R)VAD+C is an effective regimen with very low toxicity. In addition to the MIPI score, Ki67 expression provides additional independent prognostic information for the prediction of overall survival (ClinicalTrials.gov Identifier: NCT00285389).

The authors report a case of nasal-type natural killer/T (NK/T)-cell lymphoma in a 15 years old girl, with rapid fatal evolution. NK/T proliferations are very rare and only a few cases have been described in children, most of them NK/T-cell lymphoma or leukemia, but not nasal-type NK/T-cell lymphoma. Clinical and biologic characteristics of these diseases are discussed with focus on their aggressivity and poor response to conventional chemotherapy.

PURPOSE: To determine the efficacy and toxicity of chemoimmunotherapy followed by either whole-brain radiotherapy (WBRT) or intensive chemotherapy and autologous stem-cell transplantation (ASCT) as a first-line treatment of primary CNS lymphoma (PCNSL). PATIENTS AND METHODS: Immunocompetent patients (18 to 60 years of age) with untreated PCNSL were randomly assigned to receive WBRT or ASCT as consolidation treatment after induction chemotherapy consisting of two cycles of R-MBVP (rituximab 375 mg/m2 day (D) 1, methotrexate 3 g/m2 D1; D15, VP16 100 mg/m2 D2, BCNU 100 mg/m2 D3, prednisone 60 mg/kg/d D1-D5) followed by two cycles of R-AraC (rituximab 375 mg/m2 D1, cytarabine 3 g/m2 D1 to D2). Intensive chemotherapy consisted of thiotepa (250 mg/m2/d D9; D8; D7), busulfan (8 mg/kg D6 through D4), and cyclophosphamide (60 mg/kg/d D3; D2). WBRT delivered 40 Gy (2 Gy/fraction). The primary end point was 2-year progression-free survival. Cognitive outcome was the main secondary end point. Analysis was intention to treat in a noncomparative phase II trial. RESULTS: Between October 2008 and February 2014, 140 patients were recruited from 23 French centers. Both WBRT and ASCT met the predetermined threshold (among the first 38 patients in each group, at least 24 patients were alive and disease free at 2 years). The 2-year progression-free survival rates were 63% (95% CI, 49% to 81%) and 87% (95% CI, 77% to 98%) in the WBRT and ASCT arms, respectively. Toxicity deaths were recorded in one and five patients after WBRT and ASCT, respectively. Cognitive impairment was observed after WBRT, whereas cognitive functions were preserved or improved after ASCT. CONCLUSION: WBRT and ASCT are effective consolidation treatments for patients with PCNSL who are 60 years of age and younger. The efficacy end points tended to favor the ASCT arm. The specific risk of each procedure should be considered.

BACKGROUND: Radioimmunotherapy represents a potential option as consolidation after chemoimmunotherapy in patients with diffuse large B-cell lymphoma who are not candidates for transplantation. We aimed to assess activity and toxicity of fractionated radioimmunotherapy using anti-CD22 90Y-epratuzumab tetraxetan as consolidation after front-line induction chemoimmunotherapy in untreated elderly patients with diffuse large B-cell lymphoma. METHODS: We did a prospective, single-group, phase 2 trial at 28 hospitals in France, with patients recruited from 17 hospitals. Eligible patients were aged 60-80 years with bulky stage 2-3 or stage 3-4 CD20-positive diffuse large B-cell lymphoma, previously untreated, and not eligible for transplantation. Patients received six cycles of R-CHOP (rituximab [375 mg/m2], cyclophosphamide [750 mg/m2], doxorubicin [50 mg/m2], and vincristine [1·4 mg/m2, up to 2 mg] all on day 1, and prednisone [40 mg/m2] daily for 5 days), administered every 14 days. 6-8 weeks after R-CHOP, responders received two doses of 15 mCi/m2 (555 MBq/m2) 90Y-epratuzumab tetraxetan administered 1 week apart. The primary endpoint was 2 year event-free survival in all registered eligible patients who received at least 1 day of study treatment; the safety analysis was done in the same population. This trial is registered with ClinicalTrials.gov, number NCT00906841. FINDINGS: Between Oct 22, 2008, and Dec 16, 2010, we recruited 75 patients, of whom four (5%) were excluded after central pathology review; hence, 71 (95%) patients were included in the analysis. All patients started induction treatment; 57 (80%) received radioimmunotherapy. With a median follow-up of 37 months (IQR 30-44), the estimated 2 year event-free survival was 75% (95% CI 63-84). Radioimmunotherapy toxicity consisted of grade 3-4 thrombocytopenia in 48 (84%) of 57 patients and neutropenia in 45 (79%) of 57 patients. One patient developed myelodysplastic syndrome 28 months after receiving radioimmunotherapy and one patient developed acute myeloid leukaemia 5 months after receiving radioimmunotherapy. INTERPRETATION: Fractionated radioimmunotherapy with 90Y-epratuzumab tetraxetan might be appropriate for response consolidation after induction chemotherapy in older patients with advanced diffuse large B-cell lymphoma, but further comparative studies are needed. FUNDING: Immunomedics, Amgen, Canceropôle Grand Ouest, the GOELAMS/LYSA group and the French National Agency for Research (Investissements d'Avenir).

OBJECTIVE: The economic profile of acute myeloid leukaemia (AML) is badly known. The few studies published on this disease are now relatively old and include small numbers of patients. The purpose of this retrospective study was to evaluate the induction-related cost of 500 patients included in the AML 2001 trial, and to determine the explanatory factors of cost. SETTING: "Induction" patient's hospital stay from admission for "induction" to discharge after induction. METHOD: The study was performed from the French Public Health insurance perspective, restrictive to hospital institution costs. The average management of a hospital stay for "induction" was evaluated according to the analytical accounting of Besançon University Teaching Hospital and the French public Diagnosis-Related Group database. Multiple linear regression was used to search for explanatory factors. MAIN OUTCOME MEASURE: Only direct medical costs were included: treatment and hospitalisation. RESULTS: Mean induction-related direct medical cost was estimated at 41,852 ± 6,037, with a mean length of hospital stay estimated at 36.2 ± 10.7 days. After adjustment for age, sex and performance status, only two explanatory factors were found: an additional induction course and salvage course increased induction-related cost by 38% (± 4) and 15% (± 1) respectively, in comparison to one induction. These explanatory factors were associated with a significant increase in the mean length of hospital stay: 45.8 ± 11.6 days for 2 inductions and 38.5 ± 15.5 if the patient had a salvage course, in comparison to 32.9 ± 7.7 for one induction (P < 10â»4). This result is robust and was confirmed by sensitivity analysis. CONCLUSION: Consideration of economic constraints in health care is now a reality. Only the control of length of hospital stay may lead to a decrease in induction-related cost for patients with AML.

BACKGROUND: In 1981, the authors developed an original strategy combining 3 cycles of doxorubicin (adriamycin), bleomycin, vinblastine, and dacarbazine (ABVD) or ABVD-like chemotherapy and extended high-dose radiation for treating patients with clinical stages IIIB and IV Hodgkin lymphoma (HL). In the current study, the authors analyzed the 20-year results of this treatment as applied to 213 patients according to 2 successive trials. METHODS: All patients who responded to chemotherapy received extended high-dose radiation. The rates of complete remission (CR), freedom from disease progression (FFP), HL-specific survival (HLSS), second tumors and cardiac events, freedom from treatment-associated mortality (FFTM), overall survival (OS), and event-free survival were calculated. RESULTS: In December 2006, the median follow-up of the surviving patients exceeded 13 years; 102 patients (48%) achieved a CR after chemotherapy and 178 patients (84%) did so after radiotherapy. The rates of FFP (61%, quasi-stable after 6 years) and HLSS (81.6%, stable after 12 years) were found to be significantly higher in patients who achieved a CR after chemotherapy. The incidence of hematologic malignancies was 10.9% (with 10 of 12 events occurring within the first 7 years). The rates of solid tumors (32.4%), cardiac events (33.4%), and FFTM (65.6%) did not reach any plateau by 20 years and were found to be significantly associated with patient age. The 20-year OS rate was 48%. CONCLUSIONS: This combined modality treatment gave long-term results similar to those obtained using 6 to 8 cycles of ABVD. Response to the initial brief chemotherapy administration was found to be predictive of the FFP and HLSS rates. The low rate of FFTM was the result of extended high-dose radiation. The results of the current study should help to design future trials for treating patients with advanced stages of HL.

BACKGROUND: The 5-year freedom from treatment failure (FFTF) rate, with treatment failure defined as the lack of post-treatment complete remission (CR), recurrence, or death, ranges from 60% to 70% after 6 to 8 cycles of combined doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), which is the reference treatment for patients with advanced Hodgkin lymphoma (HL). In this randomized, phase 2 study, the authors tested 2 intensive chemotherapy regimens in 158 patients with clinical stage (CS) IIB through IV HL accompanied by high-risk factors who were recruited between May 1997 and December 2004. METHODS: High-risk CS IIB, III, and IV were defined by the presence of > or =5 involved lymphoid areas, and/or a mediastinal mass ratio > or =0.45, and/or > or =2 extra lymph node sites affected by the disease (for CS IV). In Arm V, 82 patients received 3 courses of combined vindesine (5 mg/m(2)), doxorubicin (99 mg/m(2)), carmustine (140 mg/m(2)), etoposide (600 mg/m(2)), and methylprednisolone (600 mg/m(2)) (VABEM) followed by low-dose lymph node irradiation. In Arm A, 76 patients received 4 cycles of ABVD followed by myeloablative combined carmustine (300 mg/m(2)), etoposide (800 mg/m(2)), cytarabine (1600 mg/m(2)), and melphalan (140 mg/m(2)) and underwent autologous stem cell transplantation. RESULTS: After 3 cycles of VABEM, the CR rate was 89% versus 60% after 4 cycles of ABVD. However, after the completion of treatment, the CR rates for Arms V and A were similar (89% and 88%, respectively). The 5-year FFTF rates for Arms V and A also were similar (79% and 75%, respectively) along with the 5-year overall survival rates (87% and 86%, respectively). CONCLUSIONS: Early intensification (Arm V) and late intensification (Arm A) were equally effective for treating patients with high-risk/advanced HL.

PURPOSE: Aggressive T-cell lymphomas (ATCLs) represent 10% to 15% of non-Hodgkin's lymphomas (NHLs) in adults. ATCLs show a worse prognosis than B-cell lymphomas. PATIENTS AND METHODS: On behalf of the Société Française de Greffe de Moëlle et de Thérapie Cellulaire, we conducted a retrospective analysis including 77 ATCL patients who underwent allogeneic stem-cell transplantation (alloSCT). RESULTS: The different diagnosis included anaplastic large-cell lymphoma (ALCL; n = 27), peripheral T-cell lymphoma not otherwise specified (PTCL-NOS; n = 27), angioimmunoblastic T-cell lymphoma (AITL; n = 11), hepatosplenic gamma/delta lymphoma (HSL; n = 3), T-cell granular lymphocytic leukemia (T-GLL; n = 1), nasal natural killer (NK)/T-cell lymphoma (nasal-NK/L; n = 3) or non-nasal NK/T-cell lymphoma (non-nasal-NK/L; n = 2), enteropathy-type T-cell (n = 1), and human T-lymphotropic virus (HTLV)-1 lymphoma (n = 2). Fifty-seven patients received a myeloablative conditioning regimen. Donors were human leukocyte antigen (HLA)-matched in 70 cases and related in 60 cases. Thirty-one patients were in complete remission (CR) at the time of alloSCT, whereas 26 were in partial response (PR). Five-year toxicity-related mortality (TRM) incidence was 33% (95% CI, 24% to 46%). The 5-year overall survival (OS) and event-free survival (EFS) rates were 57% (95% CI, 45% to 68%) and 53% (95% CI, 41% to 64%), respectively. In multivariate analysis, chemoresistant disease (stable, refractory, or progressing disease) at the time of alloSCT and the occurrence of severe grade 3 to 4 acute graft-versus-host disease (aGVHD) were the strongest adverse prognostic factors for OS (P = .03 and .03, respectively). Disease status at transplantation significantly influenced the 5-year EFS (P = .003), and an HLA-mismatched donor increased TRM (P = .04). CONCLUSION: We conclude that alloSCT is a potentially efficient therapy for NK/T lymphomas and is worth further investigation through prospective clinical trials.

Tumor-associated macrophages (TAMs), the most abundant immunosuppressive cells in the tumor microenvironment, originate from blood monocytes and exhibit an IL-10(high)IL-12(low) M2 profile. The factors involved in TAM generation remain unidentified. We identify here leukemia inhibitory factor (LIF) and IL-6 as tumor microenvironmental factors that can promote TAM generation. Ovarian cancer ascites switched monocyte differentiation into TAM-like cells that exhibit most ovarian TAM functional and phenotypic characteristics. Ovarian cancer ascites contained high concentrations of LIF and IL-6. Recombinant LIF and IL-6 skew monocyte differentiation into TAM-like cells by enabling monocytes to consume monocyte-colony-stimulating factor (M-CSF). Depletion of LIF, IL-6, and M-CSF in ovarian cancer ascites suppressed TAM-like cell induction. We extended these observations to different tumor-cell line supernatants. In addition to revealing a new tumor-escape mechanism associated with TAM generation via LIF and IL-6, these findings offer novel therapeutic perspectives to subvert TAM-induced immunosuppression and hence improve T-cell-based antitumor immunotherapy efficacy.
