Long-term outcomes of high dose treatment and autologous stem cell transplantation in follicular and mantle cell lymphomas – a single centre experience



Advanced follicular lymphoma (FL) and mantle cell lymphoma (MCL) are incurable diseases with conventional treatment. The high dose treatment (HDT) with autologous stem cell transplantation (ASCT), however, offers a certain proportion of these patients the prospect of a prolonged disease-free and overall survival. The aim of this study was to investigate the event free survival (EFS) and overall survival (OS) in patients with FL and MCL treated with ASCT.

Patients and methods

Seventeen patients with FL and 29 patients with MCL were included, 15 of them were transplanted to consolidate the response to second line treatment and 24 to consolidate their first remission, respectively. All were conditioned with total body irradiation (TBI) and high dose cyclophosphamide between 2006 and 2014 and all were transplanted with peripheral blood stem cells.


The estimated 5-year OS for FL was 87.8% (95% confidence interval [CI] 59.5%–96.8%) and for MCL 79.3% (95% CI 56.1%–91.1%), respectively. The estimated 5-year EFS for FL was 76.0% (95% CI 48.0%–90.3%) and for MCL 69.8% (95% CI 45.5%–84.8%), respectively. There were no secondary hematological malignancies observed in either group.


Based on above results, the ASCT with TBI is a good treatment option in terms of long-term survival for patients with follicular and mantle cell lymphoma demonstrating a relatively low rate of late toxicities and secondary malignancies.

Follicular lymphoma (FL) is nowadays still an incurable disease using standard chemotherapy.1 Even though it is very sensitive to chemoand radiotherapy relapses remain the main treatment failure. Significant changes were made in the past two decades, a great gain was the addition of rituximab to the standard CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone) to prolong progression-free survival (PFS).2,3 Rituximab is now the golden standard in the first line treatment2, it also improves the overall survival (OS) in relapsed FL patients.4 In a Cochrane review in 2012, the authors demonstrated that high dose treatment (HDT) with autologous stem cell transplantation (ASCT) improves the progressionfree survival in comparison with chemotherapy or immuno-chemotherapy in previously untreated patients with FL, but does not prolong the OS.5 There is also evidence that HDT with ASCT brings benefits to patients with relapsed FL.5,6 A consensus was made in 2013 by the European Group for Blood and Marrow Transplant stating that the SCT is appropriate in patients with first chemo-sensitive relapse to consolidate remission, especially in patients with a short response after immuno-chemotherapy or with high-risk follicular lymphoma international prognostic index (FLIPI). They also pointed out that the HDT with ASCT is appropriate in second or subsequent chemo-sensitive relapses.1

Allogeneic transplantation and autologous transplantation are both possible. A higher relapse rate was observed in autologous SCT, whereas no significant difference in the disease-free survival or OS was found.7,8 Allogeneic SCT showed a lower risk for disease recurrence9,10, and that also applies for the reduced intensity conditioning SCT.8 However, higher treatment-related mortality after allogeneic SCT than after autologous was objectified. One of the factors which contributed significantly to the higher treatment-related mortality was the total body irradiation (TBI).9

The mantle cell lymphoma (MCL) is also an incurable disease and successful treatment is still a challenge. In the past few years, many induction regimens were tested for their efficacy.11-14 Since 2013, we use in our centre the alternation of rituximab-CHOP (R-CHOP) regimen with R-high dose cytarabine-based regimen for younger patients, as it was shown that it gives a better OS and a higher proportion of partial remission (PR) to complete remission (CR) conversions than other regimens.15 Nevertheless, the HDT and ASCT remain an attractive option for those with chemo-sensitive disease regardless of the induction regimen applied.12,14-16 In relapsed or refractory disease, long-term disease-free intervals have not been established, the reduced intensity conditioning transplantation is here an option.16 Secondary hematological malignancies after the SCT remain an important issue with an estimated 5 year risk of 3.8%17, although some authors report of minimum hematological malignancies or none at all.15 The allogeneic SCT offers a lower relapse rate but a higher non-relapse mortality resulting in OS similar to ASCT.18 However, it was also shown by Romera et al. that intensive chemotherapy with R-hyper-CVAD (cyclophosphamide, vincristine, doxorubicin, and dexamethasone) alternating with R-high dose methotrexate-cytarabine is also a suitable treatment option for treatment of MCL without ASCT.19 The aim of this study was to investigate the event free survival (EFS) and OS in patients with FL and MCL treated with ASCT.

Patients and methods

The study population includes 17 patients with FL and 29 patients with MCL who underwent ASCT after HDT conditioning with TBI (fractionated 6 × 200 cGy during three days’ period) and high dose cyclophosphamide (2 × 60 mg/kg) between 2006 and 2014 and whose conventional treatment and the TBI were performed at the Institute of Oncology Ljubljana and the transplantation procedure at the University Clinical Centre Ljubljana, Department of Hematology. The study was conducted according to the Helsinki Declaration, all patients were aged 18 or above and patient’s informed consent was obtained.

According to national guidelines, FL patients were transplanted in their second remission and only three patients with adverse prognostic factors were consolidated for their first remission. Conversely, MCL patients were transplanted already in their first remission and exceptionally only five patients (with low risk international prognostic index for MCL [MIPI]) were consolidated for their second or later remission. All patients included in the study were transplanted with stem cells collected from peripheral blood. All patients were also treated with maintenance rituximab post ASCT concordant with the latest studies20,21 and were treated with rituximab containing regimens in their induction treatments. Twenty-six MCL patients received R-CHOP regimen as their first induction treatment and 3 patients received R-CHOP as the second line treatment. In the FL group, only 10 patients started with R-CHOP as the first line induction treatment and 7 patients received R-CHOP after failure of first line treatment without rituximab.

The disease status prior to ASCT was evaluated according to revised Cheson’s criteria.22 The OS was measured from the time of HDT/ASCT to death from any cause. The EFS was measured from the time of HDT/ASCT to progression, recurrence of the disease, or death from any cause. The nonrelapse mortality was defined as death from any cause without progression or relapse of lymphoma. The EFS and OS were calculated according to the Kaplan-Meier method and differences between subgroups were analyzed by the log-rank test and by the Cox proportional hazards model. The nonrelapse mortality was estimated using the cumulative incidence function. The program used was R Statistical software (R for Windows, version R-3.1.2, University of Auckland) and GraphPad Prism programme (version 3.02, GraphPad Software, USA).

The survival outcomes of three patients with histologically confirmed transformation of FL into the diffuse large B-cell lymphoma at the time of HDT/ASCT were analyzed separately.


Patients’ characteristics and disease status prior to ASCT

Patients’ characteristics are shown in Table 1. In the FL group, there was a slight male predominance. Median age at diagnosis of lymphoma was 46 years. Thirteen patients had FL grade I/II and 4 patients had FL grade IIIa. None of the patients had FL grade IIIb. Four of them were considered as low risk patients (0–1 points) according to FLIPI, 9 were in the intermediate group (2 points) and 4 of them in the high risk group (3–5 points). Three patients (17.6%) were transplanted to consolidate their first remission, 14 (82.4%) were transplanted as a consolidation after treatment for their first relapse. Five (29.4%) of them were in CR before transplantation, 12 (70.6%) of them had PR. In the MCL group, there were 23 males and 6 females. Median age at diagnosis was 54 years. There were 10 pleomorphic/blastoid variants of MCL in the study population. Twenty-four patients had MIPI below 5.7 (low risk group), 4 patients between 5.7 and 6.2 (intermediate risk group) and one patient was in the high risk group (MIPI above 6.2). Twenty-four patients (82.7%) were transplanted in their first remission, 3 patients (10.3%) were transplanted to consolidate their second remission and 2 patients (6.9%) for later than second remission. Thirteen (44.8%) of them had CR before transplantation and 16 (55.2%) of them had PR.

Patients’ characteristics

Overall and event free survival

The estimated 5-year OS for FL was 87.8% (95% confidence interval [CI] 59.5%–96.8%) and the median OS has not been reached yet with a median follow-up time of 57.5 months (range 15–102 months) (Figure 1A). The FLIPI score did not influence the OS (p = 0.365, data not shown) and also the disease status had no significant impact on the OS (p = 0.570, hazard ratio (HR) 2.188, 95% CI HR 0.120–47.29).

Figure 1.
(A) Overall survival of follicular lymphoma (FL) patients (n = 17); (B) Overall survival of mantle cell lymphoma (MCL) patients (n = 29).

The estimated 5-year OS for MCL was 79.3% (95% CI 56.1%–91.1%), and the median OS has not been reached yet with a median follow-up time of 31.5 months (range 2.5 months–95.5 months) (Figure 1B). The MIPI index had no impact on OS (p = 0.776, data not shown) and the same is true for the CR or PR status prior to transplantation (p = 0.668, HR 0.679, 95% CI HR 0.117–3.952).

The estimated 5-year EFS for FL was 76.0% (95% CI 48.0%–90.3%) and is shown in Figure 2A. The FLIPI score did not influence the EFS (p = 0.124, data not shown) and also the disease status (CR or PR) prior to ASCT did not (p = 0.851, HR 0.806, 95% CI HR 0.0936–7.056).

Figure 2.

The estimated 5-year EFS for MCL was 69.8% (95% CI 45.5%–84.8%) and is shown in Figure 2B. The MIPI index had no impact on the EFS (p = 0.486, data not shown) and the same holds true for the CR or PR status prior to transplantation (p = 0.391, HR 0.485, 95% CI HR 0.099–2.472).

Non-relapse mortality and secondary malignancies

In FL group, 2 patients (11.8%) died. One patient transformed into the diffuse large-B cell lymphoma and died due to complications of a massive transformation and in one patient the cause of death was unrelated to lymphoma. In MCL group, 5 patients (17.2%) died. Two died of progression of MCL, one died due to histologically confirmed JC virus leukoencephalopathy and two of causes unrelated to lymphoma. The estimated probability of non-relapse mortality after 5 years equals 0.063 in FL (95% CI 0–0.186) and 0.116 in MCL (95% CI 0–0.245). In the FL group, 1 patient (5.9%) developed ovarian cancer (treated with surgery) and 1 patient (5.9%) bladder cancer, but there were no hematological malignancies. In MCL group, there were also no hematological malignancies, 1 patient was just suspected to have myelodysplastic syndrome due to prolonged thrombocytopenia but this suspicion was later on rejected. One patient (3.4%) developed prostate cancer and is receiving hormone treatment.


Survival analyses were done also for the 3 patients with transformation of FL into the diffuse largeB cell lymphoma at the time of HDT and ASCT. Median age of these patients was 42 years (range 39–52). There were 2 males and one female. The FLIPI scores were 0, 1 (low risk group) and 2 (intermediate risk group). The disease status prior transplantation was CR in all three cases, one patient was transplanted to consolidate the second remission and the other two to consolidate their third remission. They were all conditioned with TBI and high dose cyclophosphamide. Two of them died, one is still alive. With a median survival of 39.5 months the difference between the OS of those 3 patients and our FL group was not significant (p = 0.062, data not shown). The EFS, however, was in these patients significantly shorter (median EFS of 15 months) than in our FL group (p = 0.003, HR 6.805, 95% CI HR 3.414–495.6).


Follicular lymphoma

The estimated 5-year OS for our FL patients is 87.8% and the median OS has not been reached. Compared to the study of El-Najjar et al., the survival of our patients is superior since their 5-year OS for TBI-based HDT was 77% while for carmustine, etoposide, cytarabine, melphalan (BEAM) treated patients it was 74%. The difference between their treatment arms was statistically significant (p = 0.042).23 Due to our relatively small sample our CI is relatively wide, but the results are encouraging.

Our projected 8-year OS was also 87.7%, since we had no further events in that period, but the 8-year estimation is not so reliable as the sample gets smaller. Thereby, our results resemble more than ASCT studies the allogeneic transplantation studies, for example a study of Khouri et al, where they reported the 11-year OS of 78% achieved by the addition of 90Y to the fludarabine and cyclophosphamide conditioning regimen.24 Van Besien et al. conducted a study comparing allogeneic and autologous SCT. The TBI conditioning regimen was more used for allogeneic transplantation, which differs from our study. Their 5-year adjusted probabilities of survival after allogeneic transplantation were 51% and TBI was associated with higher transplant related mortality but a lower recurrence of the disease.9 Our study confirms that the TBI including regimen is also appropriate for ASCT with a low rate of secondary malignancies and late toxicities.

The estimated 5-year EFS of our patients was 76.0% (95% CI 48.0%–90.3%) which is also better than in El-Najjar et al. study, where the 5-year EFS for TBI-based HDT was 58%. Like in case of OS, the EFS was also significantly worse in patients with BEAM-based HDT (49%, p < 0.001).23 Eightytwo point four percent of our patients were transplanted for their first relapse, with the HDT and ASCT being an established treatment regimen for relapsed disease in the rituximab era.25-27 Sebban et al. namely showed no benefit of HDT and ASCT after first line treatment regarding the EFS and OS in comparison to standard chemotherapy.25

The significant difference in EFS between our patients with FL and those whose lymphomas transformed to the diffuse large-B cell lymphoma (p = 0.0034) is interesting despite the fact that our study groups were relatively small. These results emphasize the importance of appropriate patient selection for transplantation procedure as the outcome of the patients with transformation cannot compare to our FL group (at least partially on account of a small number of transformations but also on account of a significantly worse prognosis of patients having the transformation), showing that FL patients with a transformation to the diffuse large-B cell lymphoma are not ideal candidates for TBI and high dose cyclophosphamide followed by ASCT. However, the transformation cannot be predicted and for these patients an alternative salvage option should be sought – for example a different conditioning regimen.

Mantle cell lymphoma

In our study population, the estimated 5-year OS for MCL was 79.3% (95% CI 56.1%–91.1%) and the median OS has not been reached. Also in this population, our results are comparable to the ones reported by other authors11,28,29, for example by Dreyling et al. where they compared survival after TBI and ASCT versus maintenance with α-interferon after completion of induction therapy. The 3-year OS was 83% after ASCT versus 77% in the IFN group (p = 0.18).11 The prospective trial of Nordic Lymphoma Group, however, reports of a 4-year OS of 81% and a 4-year EFS of 63%, but their patients were conditioned with the BEAM regimen.30 We can also estimate the 7-year OS for our MCL as 79.3% since there were no additional events, but that estimation is not as reliable as the 5-year OS.

In a study by Oinonen et al., the median EFS was set at 39 months31, while in our group the median has not been achieved yet with a median observation period of 31.5 months. Delarue et al. revealed the same, comparing the BEAM treatment to TBI – the median EFS of patients receiving BEAM was 55 months, whereas the median EFS for the TBI regimen group has not been reached (p = 0.05).15 This again proves that TBI conditioning regimen is safe and appropriate for ASCT in MCL.

The ASCT performed in line of first line treatment to consolidate the first remission was documented to have a significantly better EFS and OS compared to delayed ASCT.11,32 In our study, the impact of early or late transplantation on OS and EFS was not statistically significant (OS: p = 0.141, HR 0.284, 95% CI HR 0.015–1.82; EFS: p = 0.393, HR 0.497, 95% CI HR 0.057–3.080). That could be due to our relatively small study group and a small proportion of transplantations to consolidate the second or further remissions. Most of our patients were namely transplanted after first line treatment.

TBI conditioning

The TBI regimen has been linked to secondary malignancies, mostly hematological – myelodysplastic syndromes (MDS) and acute myeloid leukemias (AML).17,26,33-35 The numbers vary among different studies – they range from a 5-year estimated risk of 3.8%17 to a 7-year cumulative probability of 8.9%34 and a 6-year incidence of 12%.33 The therapy-related-MDS/therapy-related-AML (t-MDS/t-AML) also depended on amount of radiation used for TBI. In Metayer et al. multicenter case-control study, there was a nonsignificant excess risk of tMDS/ tAML with use of conditioning regimens with TBI, compared with no TBI (relative risk [RR]  =  2.0; 95% CI 0.95–4.18; p =  0.07). The dose-response analysis, however, revealed that the excess risk was limited to patients receiving TBI doses of 13.2 Gy (RR  = 6.6; p  = 0 .003). Those with lower TBI doses (5–12 Gy) had no evidence of elevated risk of tMDS/tAML.34 Hypotheses on cellular level are that HDT and TBI cause similar cellular and genetic damages as the pre-transplant therapy to the hematopoietic progenitor cells and therefore provide opportunity for causing damage to the stem cells. Reinfusion of peripheral blood progenitor cells with previously damaged DNA can result in clonal abnormal hematopoiesis.35 In this study, we had no hematological malignancies in either of our groups. Even though the number of our patients is relatively small we may assume that TBI with high doses of cyclophosphamide is a safe method of conditioning prior to transplantation in regard of the secondary hematological malignancies.


Follicular lymphoma and mantle cell lymphoma remain incurable diseases even in modern era. Treatment modalities are improving and transplantation of stem cells is gaining a more and more important role each year. We present good long term survivals after autologous stem cell transplantation following conditioning with TBI and high dose cyclophosphamide with minimal toxicities and low incidence of secondary malignancies. Our study also demonstrates a low relapse rate and therefore we conclude that the autologous stem cell transplantation represents a reliable option for treatment of follicular and mantle cell lymphoma with good long term results.
