A phase II prospective study of the "Sandwich" protocol, L-asparaginase, cisplatin, dexamethasone and etoposide chemotherapy combined with concurrent radiation and cisplatin, in newly diagnosed, I/II stage, nasal type, extranodal natural killer/T-cell lymphoma.

ABSTRACT: Nasal-type, extranodal NK/T cell lymphoma (ENKTCL) is a special type of lymphomas with geographic and racial specificity. Up to now, the standard first-line treatment is still not unified. In our previous report, the "sandwich" protocol produced good results. Continuing to use the "sandwich" mode, a new chemotherapy composed of L-asparaginase, cisplatin, etoposide and dexamethasone (LVDP) plus concurrent chemoradiotherapy (CCRT) was conducted in more patients with newly diagnosed, I/II stage ENKTCL. The results showed that 66 patients were enrolled. Overall response rate was 86.4% including 83.3% complete response and 3.0% partial remission. With the median follow-up of 23.5 months, 3-year overall survival and 3-year progression-free survival were 70.1% and 67.4%, respectively. The survival rate in stage II and extra-cavity stage I was significantly less than that in limited stage I (p < 0.05). Therefore, we thought that the "sandwich" mode was worthy of being generalized and LVDP combined with CCRT was an effective protocol for I/II stage ENKTCL. But this regimen was not suitable for all stage I/II patients and warrants larger sample and layering investigation. This study was a registered clinical trial with number ChiCTR-TNC-12002353.

Phase II trial of concurrent chemoradiotherapy with L-asparaginase and MIDLE chemotherapy for newly diagnosed stage I/II extranodal NK/T-cell lymphoma, nasal type (CISL-1008).

Project description:We designed a new treatment protocol incorporating concurrent administration of L-asparaginase (to reduce the probability of systemic progression during concurrent chemoradiotherapy (CCRT)) plus high-dose methotrexate to consolidation chemotherapy to intensify the regimen for treating localized extranodal NK/T cell lymphoma, nasal type (ENKTL). CCRT comprised radiation (36-44 Gy) with weekly cisplatin (30 mg/m2) and tri-weekly L-asparaginase (4 000 IU). Chemotherapy-MIDLE (methotrexate 3 g/m2 on day 1, etoposide 100 mg/m2 and Ifosfamide 1 000 mg/m2 on days 2-3, dexamethasone 40 mg on days 1-4, and L-asparaginase 6 000 IU/m2 on days 4, 6, 8, 10)-was repeated every 28 days for two cycles. One of the 28 patients developed distant lesions after CCRT. The final complete response rate was 82.1%. Four patients dropped out during or after their first MIDLE cycle due to toxicities (recurrent G3 hyperbilirubinemia [n = 1], G3-5 increased creatinine [n = 2], and G5 infection [n = 1]). With a median follow-up of 46 months (95% CI: 39-47 months), the estimated 3-year progression-free survival rate and overall survival rate were 74.1% and 81.5%, respectively. This MIDLE protocol may be effective for localized ENKTL. However, concurrent administration of L-asparaginase during CCRT does not seem to provide additional benefits.

Phase II study of sequential chemoradiotherapy with L-asparaginase, dexamethasone, ifosfamide, cisplatin, and etoposide (DICE-L) in the early stage of extranodal natural killer (NK)/T-cell lymphoma.

Project description:BackgroundTo explore a more effective treatment strategy for newly diagnosed stage I and II extranodal natural killer/T-cell lymphoma (ENKTL), nasal type, we conducted a prospective phase II study of sequential chemoradiotherapy with the L-asparaginase, dexamethasone, ifosfamide, cisplatin, and etoposide (DICE-L) regimen.MethodsPatients with newly diagnosed stage I and II ENKTL in the upper-aerodigestive tract were enrolled. Treatment was comprised of up to 4 cycles of DICE-L followed by 50 Gy of intensity modulated radiation therapy (IMRT) to the involved field. The primary endpoint was the complete response (CR) rate. The secondary endpoints were the objective response rate (ORR), the 5-year overall survival (OS) rate, the 5-year progression-free survival (PFS) rate, and safety.ResultsA total of 81 patients were enrolled from June 2009 to May 2012 in Shanghai Cancer Hospital. Among these patients, 68 patients achieved CR and 1 patient achieved partial response (PR). The CR rate was 84%, and the ORR was 85.2%. With a median follow up of 88.1 months, the 5-year OS and 5-year PFS rates were 82.4% and 63.4%, respectively. The most common adverse events were grade 3 to 4 neutropenia (73.5%) and febrile neutropenia (21%).ConclusionsSequential chemoradiotherapy using DICE-L followed by radiotherapy is an effective treatment modality for stage I to IIE ENKTL and is safe with acceptable toxicity.

A Phase II Study of Methotrexate, Etoposide, Dexamethasone and Pegaspargase Sandwiched with Radiotherapy in the Treatment of Newly Diagnosed, Stage IE to IIE Extranodal Natural-Killer/T-Cell Lymphoma, Nasal-Type.

Project description:A phase II study of methotrexate, etoposide, dexamethasone, and pegaspargase (MESA) sandwiched with radiotherapy for newly diagnosed, stage IE-IIE extranodal natural-killer/T-cell lymphoma, nasal-type (ENKTL) was conducted to explore its clinical efficacy and safety, as well as novel serum biomarkers upon anti-metabolic treatment.Four cycles of MESA sandwiched with radiotherapy were administered. The primary end point was the overall response rate (ORR). Serum metabolomic profiles were assessed by liquid chromatography-mass spectrometry, with specific metabolites quantified by targeted metabolic analysis.Forty patients were enrolled and the ORR was 92.1% (95%CI, 83.1%-100.0%). The 2-year progression-free survival (PFS) rate was 89.1% and overall survival (OS) rate was 92.0%. Grade 3/4 non-hematologic and hematologic toxicities were observed in 17 (42.5%) and 26 patients (65·0%) during chemotherapy, and in 9 (22.5%) and 0 (0.0%) patients during radiotherapy, respectively. Fifty-six significantly decreased and 59 increased metabolites were identified in ENKTL, as compared to healthy volunteers. A predictive principal components analysis model of asparaginase-associated metabolites, asparaginase-associated metabolic score (AspM), was established, including alanine, aspartate, glutamate, and succinic acid. Patients with high AspM score displayed superior survival and prognostic significance of AspM was validated in a historical cohort of early and advanced-stage ENKTL treated with asparaginase-based regimens. Multivariate analysis confirmed AspM as a prognostic score independent of PINK and PINK combined with Epstein-Barr virus DNA.MESA sandwiched with radiotherapy is an effective and safe regimen for early-stage ENKTL. AspM score may be a promising prognostic index of serum metabolites in addition to clinical prognostic index in ENKTL.

Comparison of Native Escherichia coli L-Asparaginase versus Pegylated Asparaginase, in Combination with Ifosfamide, Methotrexate, Etoposide, and Prednisolone, in Extranodal NK/T-Cell Lymphoma, Nasal Type.

Project description:PurposeThe aim of this study was to compare asparaginase-related toxicities in two asparaginase preparations, namely native Escherichia coli L-asparaginase (L-ASP) and pegylated asparaginase (PEG-ASP) in combination with ifosfamide, methotrexate, etoposide, and prednisolone (IMEP) in natural killer (NK)/T-cell lymphoma (NTCL).Materials and methodsA total of 41 NTCL patients who received IMEP plus native E. coli L-ASP or PEG-ASP at Seoul National University Hospital were included in this study between January 2013 and March 2016. IMEP/ASP treatment consisted of ifosfamide, methotrexate, etoposide, plus native E. coli L-ASP (6,000 IU/m2 on days 1, 3, 5, 7, 9, and 11) or PEG-ASP (2,500 IU/m2 on day 1) every 3 weeks. ASP-related toxicities, toxicity patterns, length of hospital stay, and clinical outcomes were compared between the different treatment groups.ResultsThe frequency of ASP-related toxicities was similar between the IMEP plus native E. coli L-ASP group and the PEG-ASP group apart from hypofibrinogenemia (native E. coli L-ASP vs. PEG-ASP group, 86.4% vs. 36.8%; p=0.001). Although post-treatment transaminase and albumin levels were significantly high and low, respectively, hepatotoxicity gradients before and after treatment did not differ significantly between the groups. Since PEG-ASP was given at an outpatient clinic in some patients, length of hospital stay was significantly shorter in the IMEP plus PEG-ASP group (median, 4.0 vs. 6.0 days; p=0.002). A favorable tendency of clinical outcomes was observed in NTCL patients treated with IMEP plus PEG-ASP (complete remission rate, 73.7% vs. 45.5%; p=0.067).ConclusionIMEP plus PEG-ASP showed similar ASP-related toxicities, shorter length of hospital stay, and a trend towards improved clinical outcomes compared with IMEP plus native E. coli L-ASP in NTCL.

A phase 2 study of methotrexate, etoposide, dexamethasone, and pegaspargase chemotherapy for newly diagnosed, relapsed, or refractory extranodal natural killer/T-cell lymphoma, nasal type: a multicenter trial in Northwest China.

Project description:The nasal type of extranodal natural killer/T-cell lymphoma is a rare aggressive lymphoma with poor prognosis. To discover a successful treatment, we investigated the efficacy and safety of chemotherapy with methotrexate, etoposide, dexamethasone, and polyethylene glycol-asparaginase (MESA). Three cycles of MESA were administered to 46 patients with new or relapsed/refractory natural killer/T-cell lymphoma. Complete response after 3 treatment cycles was 43.5%, the overall response rate was 87%, and 2-year overall survival was 83.4%. Complete response was significantly better for newly diagnosed patients than for patients with relapsed/refractory disease. Patients with newly diagnosed disease had a significantly better overall response rate after 1, but not after 2 or 3 treatment cycles. Overall survival and progression-free survival did not differ over 2 years. Grade 1/2 toxicities were frequent, but MESA was associated with fewer grade 3/4 events or treatment-related deaths. These results will require confirmation in larger prospective trials.

The DDGP (cisplatin, dexamethasone, gemcitabine, and pegaspargase) regimen for treatment of extranodal natural killer (NK)/T-cell lymphoma, nasal type.

Project description:Extranodal natural killer/T cell lymphoma (ENKL) is a high invasive disease with poor prognosis. Since there is no consensus on standard chemotherapy, we developed an original chemotherapeutic DDGP (cisplatin, dexamethasone, gemcitabine, and pegaspargase) regimen. We retrospectively analyzed 80 patients who received DDGP chemotherapy. The primary end point was progression-free survival (PFS) and secondary end points were overall survival (OS), complete response rate (CRR), and overall response rate (ORR). The one-year PFS and OS rates were 86.0% and 88.6%, and the 2-year PFS and OS rates were 81.40% and 87.1%, respectively. The ORR and CRR of DDGP chemotherapy were 91.3% and 60.0%. The major adverse events were myelosuppression, digestive tract toxicities, and coagulation disorder. No treatment-related deaths were observed. Our results suggest that the DDGP regimen is a high effective and safe treatment for ENKL.

Five-year analysis from phase 2 trial of "sandwich" chemoradiotherapy in newly diagnosed, stage IE to IIE, nasal type, extranodal natural killer/T-cell lymphoma.

Project description:The "sandwich" protocol, was first proposed by us and comprised of l-asparaginase, vincristine, and prednisone chemotherapy with radiotherapy, results in 2-year overall survival and progression-free survival rates that surpass traditional therapies for patients with newly diagnosed, stage IE-IIE, nasal type, extranodal natural killer/T-cell lymphoma. The results had been published by cancer. These patients were followed up over a median period of 67 months, for which updates and the results of prognostic factors analyses are presented. The 5-year overall survival and progress-free survival rates were both 64%. The highest rates of death occurred during the first 6 months, and between the second and third year after enrollment. The initial therapeutic response (odds ratio = 5.83; P = 0.001) and B symptoms (odds ratio = 6.13; P = 0.043) were significant prognostic factors for overall survival. However, the international prognostic index was not significant for progress-free survival and overall survival. There were no severe long-term side effects. These results indicate that the "sandwich" protocol may benefit the long-term survival of patients with newly diagnosed stage IE-IIE, nasal type, extranodal natural killer/T-cell lymphoma. However, additional studies with larger samples are required to confirm these results. This study is registered at www.Chictr.org (ChicTR-TNC-09000394).

A phase II study of ifosfamide, methotrexate, etoposide, and prednisolone for previously untreated stage I/II extranodal natural killer/T-cell lymphoma, nasal type: a multicenter trial of the Korean Cancer Study Group.

Project description:BackgroundCombination chemotherapy consisting of ifosfamide, methotrexate, etoposide, and prednisolone (IMEP) was active as first-line and second-line treatment for extranodal natural killer/T-cell lymphoma (NTCL).MethodsForty-four patients with chemo-naïve stage I/II NTCL were enrolled in a prospective, multicenter, phase II study and received six cycles of IMEP (ifosfamide 1.5 g/m(2) on days 1-3; methotrextate 30 mg/m(2) on days 3 and 10; etoposide 100 mg/m(2) on days 1-3; and prednisolone 60 mg/m(2) per day on days 1-5) followed by involved field radiotherapy (IFRT).ResultsOverall response rates were 73% (complete remission [CR] in 11 of 41 evaluable patients [27%]) after IMEP chemotherapy and 78% (CR 18 of 27 evaluable patients [67%]) after IMEP followed by IFRT. Neutropenia and thrombocytopenia were documented in 33 patients (75%) and 7 patients (16%), respectively. Only 8 patients (18%) experienced febrile neutropenia. Three-year progression-free survival (PFS) and overall survival (OS) were 66% and 56%, respectively. High Ki-67 (?70%) and Ann Arbor stage II independently reduced PFS (p = .004) and OS (p = .001), respectively.ConclusionDue to the high rate of progression during IMEP chemotherapy, IFRT needs to be introduced earlier. Moreover, active chemotherapy including an l-asparaginase-based regimen should be use to reduce systemic treatment failure in stage I/II NTCL.

A Multicenter Retrospective Comparison of Sequential versus Sandwich Chemoradiotherapy for Stage IE-IIE Extranodal Natural Killer/T-Cell Lymphoma, Nasal Type.

Project description:Background: Chemotherapy and radiotherapy are critical for treating early-stage extranodal natural killer/T-cell lymphoma, nasal type (ENKTL); however, the optimal therapy sequence remains unclear. Therefore, we performed this study to compare the efficacy of L-asparaginase/pegaspargase-based sequential versus sandwich chemoradiotherapy for patients newly diagnosed with stage IE-IIE ENKTL. Methods: Patients were categorized into sequential (N = 111) and sandwich (N = 104) groups. Chemotherapy regimens included GELOX, SMILE, and VLP. The median radiotherapy dose was 55.0 Gy (range, 40.0-63.0 Gy). Adverse events, treatment responses, and survival outcomes were analyzed. Results: Patients' clinical characteristics were largely comparable between the 2 groups; however, the sandwich group comprised a larger number of Ann Arbor stage IIE patients. Local invasion was the most significant predictor of overall survival (OS); local invasion and Ann Arbor stage were significant predictors of progression-free survival (PFS). There were no significant differences in the complete response rate (85.6% vs. 89.4%, p = 0.396), 3-year OS (77.5% vs. 80.8%, p = 0.636), or 3-year PFS rates (74.8% vs. 76.9%, p = 0.806) in the sequential vs. sandwich groups, respectively. The incidence of grade 3/4 hematological toxicities was higher in the sandwich group than in the sequential group (27.9% vs. 15.3%, respectively, p = 0.025). The response rates and survival outcomes in stage IE and IIE patients did not differ between sequential and sandwich groups. Conclusions: In the era of L-asparaginase/pegaspargase, both sequential and sandwich chemoradiotherapy are safe and similarly effective in patients with newly diagnosed stage IE-IIE ENKTL.

Efficacy and safety of cisplatin, dexamethasone, gemcitabine and pegaspargase (DDGP) regimen in newly diagnosed, advanced-stage extranodal natural killer/T-cell lymphoma: interim analysis of a phase 4 study NCT01501149.

Project description:To explore a more effective treatment for newly diagnosed, advanced-stage extranodal natural killer/T-cell lymphoma, nasal type (ENKTL), we conducted a phase 4 study of the cisplatin, dexamethasone, gemcitabine, pegaspargase (DDGP) regimen. The primary end point was the 2-year progression-free survival (PFS) after the protocol treatment. Secondary endpoints included response rate (RR), overall survival (OS) and median survival time (MST). The interim analysis included data only from March 2011 to September 2013, who received six cycles of DDGP chemotherapy. A total of 25 eligible patients were enrolled. Seventeen patients (17/24, 70.83%) achieved complete response (CR) and four (4/24, 16.67%) achieved partial response (PR), three (3/24, 12.50%) had progressive disease (PD). The RR after treatment was 87.50%. After a median follow-up duration of 24.67 months (range 4-48 months). The 2-year PFS and OS rate were 61.80% (95% CI, 42.00% to 81.60%) and 68.50 % (95% CI, 48.70% to 88.30%), respectively. The MST was 36.55 months (95% CI, 29.41 months to 43.70 months). Grade 3/4 leukopenia occurred in fourteen patients (58.33%) and grade 3/4 thrombocytopenia occurred in eleven patients (45.83%). Twelve patients (50.00%) experienced Activated Partial Phromboplastin Ptime (APTT) elongation and fourteen patients (58.33%) experienced hypofibrinogenemia. In conclusion, DDGP regimen is an effective and tolerated treatment for newly diagnosed, advanced-stage ENKTL. This trial was registered at www.ClinicalTrials.gov as #NCT01501149.
