Substantial for OS: bone marrow involvement at diagnosis (p=0.004) and response to induction chemotherapy(p=0.050). Clinical stage at diagnosis and the presence of B symptoms tended to impact OS (p = 0.099 and 0.066, respectively). Poor PFS was related using the presence of B symptoms at diagnosis (p=0.023), bone marrow involvement at diagnosis (p=0.002), and major induction failure (p=0.004). In multivariate analysis, bone marrow involvement at diagnosis and main induction failure remained important for each OS and PFS (Table 4). In contrast, histology form (ALK-positive and ALKunknown ALCL vs other types), LDH at diagnosis, extranodal involvement, mediastinal lymph nodes involvement, the amount of pre-transplant chemotherapy lines, along with the disease status at transplant (CR vs PR) had been predictive for neither OS nor PFS (Table three).Ann Hematol (2013) 92:925?33 Fig. 1 Kaplan eier estimates of all round survival (OS) and progression-free survival (PFS) for the entire groupTable 3 Univariate analysis of prognostic variables connected with general survival and progression-free survival Group Ann Arbor stage I I III V B symptoms at diagnosis No Yes Bone marrow involvement at diagnosis No Yes Response to induction regimen PR Principal refractorinessa Disease status at transplant CR much less than CR Quantity of prior chemotherapy regimen 1 two or extra Histology ALK-positive and ALK-unknown ALCL Other forms ALCL-all subtypes PTCL-NOS and AITL ALK-positive and ALK-unknown ALCL ALK-negative ALCL PTCL-NOS AITL No. 5-year OS (95 CI) p value 5-year PFS (95 ) p value14 50 14 51 44 16 53 12 36 29 19 46 13 52 20 45 13 7 3684.1783624-20-3 custom synthesis 6 (57.eight?five.7) 53.0 (36.five?eight.8) 83.3 (55.1?5.three) 53.eight (37.three?9.five) 69.2 (50.9?two.9) 34.9 (15.1?1.9) 66.0 (49.9?9.1) 41.0 (16.six?0.9) 65.7 (46.9?0.6) 57.1 (35.5?6.3) 77.2 (53.7?0.7) 56.8 (40.7?1.six) 54.2 (26.two?9.eight) 63.three (47.1?7.0) 63.six (38.8?two.8) 60.7 (43.4?five.7) 54.2 (26.two?9.8) 83.three (43.7?7.0) 60.7 (42.3?6.five) 55.six (18.0?7.7)0.78.six (52.three?2.five) 52.1 (36.eight?7.0) 85.1 (58.8?five.8) 51.5 (36.6?six.two) 69.9 (53.7?two.3) 24.1 (8.8?1.1) 65.two (50.0?7.eight) 33.3 (6.6?0.0) 64.5 (46.3?9.three) 54.7 (36.5?two.9) 78.7 (56.6?0.8) 51.7 (36.9?six.2) 59.eight (33.four?1.5) 59.3 (44.four?2.six) 63.8 (41.7?1.3) 57.5 (41.5?2.1) 59.8 (33.four?1.five) 71.four (35.8?1.8) 55.eight (39.0?1.three) 55.6 (18.0?7.7)0.0.0.0.0.0.0.0.0.0.0.0.70 0.77 0.0.89 0.70 0.OS general survival, PFS progression-free survival, CI self-assurance interval, CR full response, PR partial response, ALK anaplastic lymphoma kinase, ALCL anaplastic huge cell lymphoma, PTCL peripheral T cell lymphoma, NOS not otherwise specified, AITL angioimmunoblastic T cell lymphomaaLess than PR930 Table four Summary of benefits from general survival and progression-free survival Cox modelAnn Hematol (2013) 92:925?GroupOverall survival HR (95 CI) p valueProgression-free survival HR (95 CI) p valueHR hazards ratio, CI confidence interval, CR total response, PR partial responseaLess than PRResponse to induction chemotherapy Principal refractorinessa vs PR three.4-Chloro-6-fluoropyrido[3,4-d]pyrimidine site 21 (1.PMID:33375773 17?.79) Marrow involvement at diagnosis Yes vs no three.85 (1.51?.78)0.023 0.four.56 (1.86?1.19) three.58 (1.55?.27)0.001 0.Overall performance of threat models in prediction of outcome soon after autoHCT Table 5 shows PIT and IPI efficiency in prediction of OS and PFS.
