- Background: The purpose was to investigate adjuvant marrow-supportive high-dose chemotherapy compared with an equitoxicity-tailored comparator arm. Patients and methods: Five hundred and twenty-five women below theage of 60 years with operated high-risk primary breast cancer were randomised to nine cycles of granulocyte colony-stimulating factor supported and individually tailored FEC (5-fluorouracil, epirubicin, cyclophosphamide), (n = 251) or standard FEC followed by marrow-supported high-dose therapy with CTCb (cyclophosphamide, thiotepa, carboplatin) therapy (n = 274), followed by locoregional radiotherapy and tamoxifen for 5 years. Results: There were 104 breast cancer relapses in the tailored FEC group versus 139 in the CTCb group (double triangular method by Whitehead, P = 0.046), with a median follow-up of all included patients of 60.8 months. The event-free survival demonstrated 121 and 150 events in the tailored FEC- and CTCb group, respectively [P = 0.074, hazard ratio (HR) 0.804, 95% confidence interval (CI) 0.633-1.022]. Ten patients in the tailored FEC regimen developed acute myeloid leukaemia (AML)/myelodysplasia (MDS). One hundred deaths occurred in the tailored FEC group and 121 in the CTCb group (P = 0.287, HR 0.866, 95% CI 0.665-1.129). Conclusion: The update of this study shows an improved outcome linked to the tailored FEC treatment in relation to breast cancer relapse, but also an increased incidence of AML/MDS. © 2007 Oxford University Press.

In: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 120, s. 1037-

Journal article (peer-reviewed)abstract
- We have published previously a prototype of a decision model for anaemic patients with myelodysplastic syndromes (MDS), in which transfusion need and serum erythropoietin (S-Epo) were used to define three groups with different probabilities of erythroid response to treatment with granulocyte colony-stimulating factor (G-CSF) + Epo. S-Epo = 500 U/l and a transfusion need of < 2 units/month predicted a high probability of response to treatment, S-Epo > 500 U/l and =2 units/month for a poor response, whereas the presence of only one negative prognostic marker predicted an intermediate response. A total of 53 patients from a prospective study were included in our evaluation sample. Patients with good or intermediate probability of response were treated with G-CSF + Epo. The overall response rate was 42% with 28.3% achieving a complete and 13.2% a partial response to treatment. The response rates were 61% and 14% in the good and intermediate predictive groups respectively. The model retained a significant predictive value in the evaluation sample (P < 0.001). Median duration of response was 23 months. Scores for global health and quality of life (QOL) were significantly lower in MDS patients than in a reference population, and fatigue and dyspnoea was significantly more prominent. Global QOL improved in patients responding to treatment (P = 0.01). The validated decision model defined a subgroup of patients with a response rate of 61% (95% confidence interval 48-74%) to treatment with G-CSF + Epo. The majority of these patients have shown complete and durable responses.

Mutated V-H genes and preferential V(H)3-21 use define new subsets of mantle cell lymphoma
- 2003
-
In: Blood. - : American Society of Hematology. - 1528-0020 .- 0006-4971. ; 101:10, s. 4047-4054

Journal article (peer-reviewed)abstract
- Mantle cell lymphoma (MCL) is believed to originate from a naive B cell. However, we recently demonstrated that a subset of MCL displayed mutated V-H genes. We also reported restricted use of certain V-H genes. To assess the prognostic impact of these new findings, we performed V-H gene analysis of 110 patients, revealing that 18 (16%) patients had mutated and 92 (84%) patients had unmutated V-H genes. Because the mutation rate was low in the mutated group (2.2%-6.7%), further investigation of the germline V-H gene in T cells from 5 patients with mutated V-H genes was carried out; results showed that the unrearranged V-H gene was identical to the published sequence. These data confirm that the base pair substitutions within the rearranged V-H genes represent hyper-mutations, and indicate germinal center exposure. However, V-H gene mutation status did not correlate with prognosis because there was no difference in clinical outcome between the unmutated and mutated groups. The most frequently used V-H genes were V(H)3-21 (21 patients) and V(H)4-34 (19 patients). A novel finding was that V(H)3-21(+) MCL almost exclusively ex-pressed X light chains and displayed highly restricted use of the V(lambda)3-19 gene. V(H)3-21(+) patients had longer median survival than the remaining patients (53 vs 34 months; P = .03), but they tended to be younger at diagnosis. The combined use Of V(H)3-21/V(lambda)3-19 suggests a possible role for antigen(s) in the pathogenesis of these tumors and indicates that V(H)3-21(+) patients constitute a new MCL entity.

Management of patients with polycythaemia vera: results of a survey among Swedish haematologists
- 2005
-
In: European Journal of Haematology. - : Wiley. - 1600-0609 .- 0902-4441. ; 74:6, s. 489-495
-
Journal article (peer-reviewed)abstract
- The prevailing attitudes regarding diagnostic and therapeutic procedures in patients with polycythaemia vera (PV) among Swedish haematologists were surveyed by way of a mailed questionnaire in August 2002. Among diagnostic procedures frequent use is reported for arterial O-2 saturation, spleen size determination, bone marrow histology, serum erythropoietin, serum cobalamins and leukocyte alkaline phosphatase score, while direct determination of the red blood cell mass is used infrequently (seldom or never by 82%). Among therapeutic modalities hydroxyurea and phlebotomy alone were most frequently used. The P-32 therapy was used at least sometimes by 57% of the physicians, and more widely in the university clinics. Anagrelide and alfa-interferon was used in a minority of patients only. The use of prophylactic acetylsalicylic acid was very variable. The majority of the physicians had an aim for their phlebotomy treatment at a level of 0.45 or less, but 21% used a level of 0.46-0.49 and 8% a level of 0.55-0.60 (in younger patients). The platelet level, at which myelosuppressive therapy was initiated, also varied, from 400 x 10(9)/L to > 1500 x 10(9)/L. It can be concluded that in practical clinical work in Sweden the diagnosis of PV is established by frequent use of serum erythropoietin, bone marrow examination and spleen size determination. The use of different therapeutic modalities is very variable. Many physicians carry out their phlebotomy treatment with less intensity compared with national and international recommendations.

A phase I/II study of the MDR modulator Valspodar (PSC 833) combined with daunorubicin and cytarabine in patients with relapsed and primary refractory acute myeloid leukemia
- 2003

In: Leukemia Research. - 0145-2126 .- 1873-5835. ; 27, s. 323-
-
Journal article (peer-reviewed)abstract
- The cyclosporine analog Valspodar (PSC 833, Novartis Pharma) is a strong inhibitor of the mdr1 gene product p-glycoprotein (pgp). A phase I/II study was conducted in order to evaluate if addition of Valspodar to treatment with daunorubicin and cytarabine, given to patients with primary refractory or relapsed acute myeloid leukemia, could increase the complete remission rate. Fifty-three patients were treated in cohorts of three to six patients. Twelve patients reached a complete remission in bone marrow, five of whom also normalized their peripheral blood values. Three patients experienced treatment-related deaths from pneumonia, liver failure and cerebral hemorrhage, respectively. It is concluded that Valspodar 10mg/kg per 24h in combination with daunorubicin 45mg/m2 for 3 days and cytarabine 1g/m2 twice daily for 4 days is tolerable in this heavily pre-treated group of patients. Due to the moderate treatment results, the phase II part of the study was ended prematurely. The modulation of only pgp did not give an obvious improvement of the treatment results in this group of patients. ⌐ 2002 Elsevier Science Ltd. All rights reserved.

Dose-densified chemoimmunotherapy followed by systemic central nervous system prophylaxis for younger high-risk diffuse large B-cell/follicular grade 3 lymphoma patients : results of a phase II Nordic Lymphoma Group study
- 2013
-
In: Annals of Oncology. - : Elsevier BV. - 0923-7534 .- 1569-8041. ; 24:5, s. 1385-1392

Journal article (peer-reviewed)abstract
- Background: Many patients with aggressive B-cell lymphomas and high clinical risk score still die of lymphoma after conventional R-CHOP chemoimmunotherapy. We hypothesized that intensified chemoimmunotherapy including systemic central nervous system (CNS) prophylaxis improves outcome and reduces the incidence of CNS-related events. Patients and methods: Inclusion criteria were age 18-65 years, primary diffuse large B-cell lymphoma or grade III follicular lymphoma without clinical signs of CNS disease and negative cerebrospinal fluid cytology, age-adjusted International Prognostic Index 2-3 and WHO performance score 0-3. Treatment consisted of six courses of R-CHOEP-14 followed by a course of high-dose cytarabine and a course of high-dose methotrexate. Primary end point was failure-free survival (FFS) at 3 years. Results: A total of 156 eligible patients with a median age of 54 years (range 20-64) were included. Three toxic deaths were observed. Three-year overall survival (OS) and FFS rates (median observation time 52 months for survivors) were 81% and 65%, respectively. Seven patients experienced CNS relapse, all within 6 months. Conclusions: The results are promising with favorable 3-year OS and FFS rates, a low toxic death rate and a lower than expected number of CNS events. CNS progression might be further reduced by earlier CNS prophylaxis. CinicalTrials.gov.identifier: NCT01502982.

Intensive chemotherapy in patients with chronic myelogenous leukaemia (CML) in accelerated or blastic phase - a report from the Swedish CML Group
- 2002
-
In: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 118, s. 1048-

Journal article (peer-reviewed)abstract
- In attempting to restore the chronic phase (CP) of chronic myelogenous leukaemia (CML), the Swedish CML group utilized an intensive chemotherapy protocol for 83 patients (aged 16-79 years) in accelerated (AP, n = 22) or blastic phase (BC, n = 61). Most patients received a combination of mitoxantrone (12 mg/m(2) /d) and etoposide (100 mg/m(2) /d) together with cytosine arabinoside (1 g/m(2) b.i.d) for 4 d. Overall, 39 patients (47%) achieved a second CP (CP2)/partial remission (PR). Responding patients < 65 years were eligible for ablative chemotherapy followed by an allogeneic (SCT) or a double autologous stem cell transplant (ASCT). Seventeen of 34 responders < 65 years failed to proceed to transplantation as a result of early disease progression (n = 15) or disease-related complications (n = 2). The remaining 17 patients underwent SCT (n = 9; including four unrelated donor SCT) or ASCT (n = 8). Only one of the eight ASCT patients had a second ASCT; the remaining seven failed because of progression (n = 5) or hypoplasia (n = 2). The median duration of CP2/PR was 6 months (range 1-72 months). Five patients achieved a longer CP2/PR than CP1. The 1 year survival was 70% for SCT/ASCT patients (median survival 21 months), 50% for responding patients overall, but only 7% for non-responders (P < 0.001). Three SCT/ASCT patients are long-term survivors (65+, 66+ and 73+ months). In conclusion, approximately half of the patients achieved a CP2/PR after intensive chemotherapy, with a clear survival advantage for responders vs non-responders. Subsequent SCT/ASCT was feasible for half of the responders (< 65 years), and one individual underwent double ASCT. Novel therapeutic options for CML patients in AP/BP are needed.
