BACKGROUND:
This study was undertaken to evaluate the prognostic value of quantitative metabolic parameters in [18F]2‐fluoro‐2‐deoxyglucose (FDG)‐positron emission tomography (PET) for diffuse large B cell lymphoma (DLBCL).METHODS:
A total of 140 DLBCL patients underwent FDG‐PET scans before rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R‐CHOP) chemotherapy. The maximal standardized uptake value (SUVmax) and total lesion glycolysis (TLG) were calculated, with the margin thresholds as 25%, 50%, and 75% of SUVmax of all lesions. Treatment outcomes were compared between groups according to metabolic parameters and the International Prognostic Index (IPI).RESULTS:
After a median follow‐up of 28.5 months (range, 5‐81 months), the 2‐year progression‐free survival (PFS) and overall survival (OS) were 83% and 87%, respectively. Among metabolic parameters, TLG at the threshold of 50% (TLG50) was significantly associated with treatment outcomes. High TLG50 values (>415.5) were associated with reduced survivals compared with low TLG50 values (≤415.5) (2‐year PFS of 73% versus 92%, P = .007; and 2‐year OS of 81% versus 93%, P = .031). High IPI score (≥3) significantly reduced OS (2‐year OS of 79% versus 90%, P = .049). Ann Arbor stage III/IV adversely affected PFS (P = .013). However, high IPI score and Ann Arbor stage of III/V did not significantly shorten PFS (P = .200) and OS (P = .921), respectively. High TLG50 values independently predicted survivals by multivariate analysis (hazard ratio = 4.4; 95% confidence interval = 1.5‐13.1; P = .008 for PFS and hazard ratio = 3.1; 95% confidence interval = 1.0‐9.6; P = .049 for OS).CONCLUSIONS:
Combined assessment of volume and metabolism (ie, TLG) is predictive of survivals in DLBCL patients who are treated with R‐CHOP. Cancer 2013. © 2012 American Cancer Society. 相似文献2.

BACKGROUND: In patients with lymphoma who had a poor prognosis, pretransplantation 18-fluorodeoxyglucose (FDG)-positron-emission tomography (PET) was important for the evaluation of response and outcome. However, little is known about the correlation of FDG-PET with post-transplantation PET. The current study was designed to ascertain whether positive pretransplantation PET images are modified by the conditioning regimen. METHODS: Sixty consecutive patients who had achieved remission and underwent consolidation by autologous stem cell transplantation (ASCT) had PET images obtained before ASCT (after 3 or 4 chemotherapy cycles) and 100 days after ASCT. The correlation was explored between the presence of abnormal 18-FDG uptake (PET positive) or its absence (PET negative) and patient outcomes. RESULTS: Before ASCT, 31 patients achieved complete remission (CR), and 23 patients achieved uncertain CR. Before ASCT, 44 patients (75%) were had negative PET images; and, after ASCT, 48 patients (80%) had negative PET images. One year after ASCT, the estimated event-free survival (EFS) rate was 80% in patients who had negative pre-ASCT PET images compared with 43% in patients who had positive pre-ASCT PET images (P = .0002). The EFS rate was 81% in patients who had negative post-ASCT PET images compared with 25% in patients who had negative post-ASCT PET images (P < .0001). In multivariate analysis, only the results for pre- and post-ASCT PET images retained prognostic value, with relative risks of failure estimated at 4.9 and 11.9, respectively. CONCLUSIONS: A positive pre-ASCT PET image indicated a high risk of ASCT failure, which was increased by a positive post-ASCT PET image. For patients with lymphoma who have positive pre-ASCT PET images, more investigations using new treatment approaches will be required. For patients who have negative pre-ASCT PET images, obtaining post-ASCT PET images does not seem to be mandatory. 相似文献

BACKGROUND:
The use of positron emission tomography (PET) scanning in Hodgkin lymphoma (HL) and aggressive non‐Hodgkin lymphoma (HG‐NHL) has recognized prognostic value in patients who are receiving chemotherapy or undergoing autologous stem cell transplantation (SCT). In contrast, the role of PET before reduced‐intensity conditioning (RIC) and followed by allogeneic SCT has not been investigated to date.METHODS:
PET was used to assess 80 patients who had chemosensitive disease (34 patients with HG‐NHL and 46 patients with HL) before they underwent allogeneic SCT: 42 patients had negative PET studies, and 38 patients had positive PET studies. Patients underwent allograft from matched related siblings (n = 41) or alternative donors (n = 39).RESULTS:
At the time of the last follow‐up, 48 patients were alive (60%), and 32 had died. The 3‐year cumulative incidence of nonrecurrence mortality and disease recurrence was 17% and 40%, respectively. The cumulative incidence of disease recurrence was significantly lower in the PET‐negative patients (25% vs 56%; P = .007), but there was no significant difference between the patients with or without chronic graft‐versus‐host disease (P = .400). The patients who had negative PET studies before undergoing allogenic SCT also had significantly better outcomes in terms of 3‐year overall survival (76% vs 33%; P = .001) and 3‐year progression‐free survival (73% vs 31%; P = .001). On multivariate analysis, overall survival was influenced by PET status (hazard ratio [HR], 3.35), performance status (HR, 5.15), and type of donor (HR, 6.26 for haploidentical vs sibling; HR, 1.94 for matched unrelated donor vs sibling).CONCLUSIONS:
The current results indicated that PET scanning appears to be an accurate tool for assessing prognosis in patients who are eligible for RIC allografting. Cancer 2010. © 2010 American Cancer Society. 相似文献4.

Diffuse large B-cell lymphoma (DLBCL) includes two prognostically important subtypes, the germinal center B-cell (GCB) and the non-GCB types. The aim of this study was to evaluate immunohistochemical approaches for predicting the survival of patients with DLBCL following autologous hematopoietic stem cell transplantation (AHSCT). We identified 62 patients with DLBCL who either had an initial complete remission (17 patients) or received salvage chemotherapy for relapsed or refractory disease (45 patients), followed by AHSCT. Tissue microarrays were immunostained with monoclonal antibodies against GCET1, CD10, BCL6, MUM1, FOXP1 and LMO2. Using the Hans algorithm, we classified 50% of the cases as GCB type, whereas the Choi algorithm classified 58% as GCB type and LMO2 was positive in 69%. However, no significant differences were found in the 5-year overall or event-free survivals using any of these approaches. In conclusion, cell of origin fails to predict survival of DLBCL patients treated with AHSCT. 相似文献

BACKGROUND.: High-dose therapy (HDT) with autologous stem cell transplantation (ASCT) is the standard treatment for patients with chemosensitive relapsed/refractory Hodgkin lymphoma (HL), but this therapy is commonly denied to patients with resistant disease. We explored the utility of HDT and ASCT for chemoresistant HL because there are few established therapies for these patients. METHODS.: Sixty-four chemoresistant HL patients underwent HDT followed by ASCT at our center. Baseline characteristics included median age = 35 years (range, 14-59 years), stage III/IV = 49 (77%), nodular sclerosis histology = 51 (80%), and prior radiation = 32 (50%). Twenty-six patients (41%) received total body irradiation (TBI)-based regimens, and 38 (59%) underwent non-TBI conditioning. RESULTS.: The estimated 5-year overall survival (OS) and progression-free survival (PFS) were 31% and 17%, respectively (median follow-up = 4.2 years). Multivariate analysis only identified year of transplant as independently associated with improved OS (P = .008) and PFS (P = .04), with patients receiving transplants in later years having better outcome. The probabilities of 3-year PFS for patients receiving transplants during 1986 to 1989, 1990 to July 1993, August 1993 to 1999, and 2000 to 2005 were 9%, 21%, 33%, and 31%, respectively. CONCLUSIONS.: These data suggest that HDT and ASCT may result in prolonged remissions and survival for a subset of chemoresistant HL patients, with improved outcomes in patients receiving transplants more recently.

18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is now an integral part of lymphoma staging and management. Because of its greater accuracy compared with CT alone, PET/CT is currently routinely performed for staging and for response assessment at the end of treatment in the vast majority of FDG-avid lymphomas and is the cornerstone of response classification for these lymphomas according to the Lugano classification. Interim PET/CT, typically performed after 2 to 4 of 6 to 8 chemotherapy/chemoimmunotherapy cycles with or without radiation, is commonly performed for prognostication and potential treatment escalation or de-escalation early in the course of therapy, a concept known as response-adapted or risk-adapted treatment. Quantitative PET is an area of growing interest. Metrics, such as the standardized uptake value, changes (Δ) in the standardized uptake value, metabolic tumor volume, and total lesion glycolysis, are being investigated as more reproducible and potentially more accurate predictors of response and prognosis. Despite the progress made in standardizing the use of PET/CT in lymphoma, challenges remain, particularly with respect to its limited positive predictive value, emphasizing the need for more specific molecular probes. This review highlights the most relevant applications of PET/CT in Hodgkin and B-cell non-Hodgkin lymphoma, its strengths and limitations, as well as recent efforts at implementing PET/CT-based metrics as promising tools for precision medicine. 相似文献

BACKGROUND:
Although convincing data exist regarding the prognostic utility of positron emission tomographic (PET)‐computed tomographic (CT) imaging in Hodgkin lymphoma and diffuse large B‐cell lymphoma, its prognostic utility both during treatment and immediately after treatment have not been systematically evaluated in a large mantle cell lymphoma (MCL) patient cohort to support its use in clinical practice.METHODS:
The authors conducted a retrospective cohort study to examine the prognostic utility of PET‐CT imaging in a uniform MCL patient cohort undergoing dose‐intensive chemotherapy (R‐HyCVAD) in the frontline setting. The primary study endpoints were progression‐free survival (PFS) and overall survival (OS). PET‐CT images were centrally reviewed for the purposes of this study using standardized response criteria.RESULTS:
Fifty‐three patients with advanced stage MCL with PET‐CT data were identified. With median follow‐up of 32 months, 3‐year PFS and OS estimates were 76% (95% confidence interval [CI], 64%‐84%) and 84% (95% CI, 72%‐90%), respectively. Interim PET‐CT status was not associated with PFS (hazard ratio [HR], 0.9; 95% CI, 0.3‐2.7; P = .8) or OS (HR, 0.6; 95% CI, 0.1‐2.9; P = .5). Post‐treatment PET‐CT status was statistically significantly associated with PFS (HR, 5.2; 95% CI, 2.0‐13.6; P = .001) and trended toward significant for OS (HR, 2.8; 95% CI, 0.8‐9.6; P = .07).CONCLUSIONS:
These data do not support the prognostic utility of PET‐CT in pretreatment and interim treatment settings. A positive PET‐CT after the completion of therapy identifies a patient subset with an inferior PFS and a trend toward inferior OS. Cancer 2012;3565–3570. © 2011 American Cancer Society. 相似文献8.

BACKGROUND:
The use of 18F‐fluorodeoxyglucose positron‐emission tomography (PET) scan has increased considerably in the clinical management of non‐Hodgkin lymphoma patients, and its role as a prognostic factor during chemotherapy has been established recently.METHODS:
Between May 2003 and May 2009, 91 newly diagnosed patients with primary mediastinal large B‐cell lymphoma (PMLBCL) and diffuse large B‐cell lymphoma (DLBCL) were treated with 12 weekly cycles of rituximab‐MACOP‐B (n = 12 patients with PMLBCL), 6 cycles of rituximab‐CHOP21 (n = 65 patients with DLBCL, aged < 60 years and 1 patient with PMLBCL), or 8 weekly cycles of rituximab‐VNCOP‐B (n = 13 DLBCL patients, aged ≥ 60 years). All patients underwent a staging PET examination at baseline and a midtreatment (interim) PET examination after 6 weeks of rituximab‐MACOP‐B treatment, 3 cycles of rituximab‐CHOP21 treatment, or 4 weeks of rituximab‐VNCOP‐B treatment and again at the end of the chemo‐immunotherapy regimen.RESULTS:
At midtreatment evaluation, 35 patients showed a persistently positive PET scan; only 6 (17%) of these patients achieved a continuous complete response (CCR). However, 56 patients presented with a negative interim PET, and 50 (89%) of these patients achieved and maintained a CCR. Comparison between the 2 PET groups indicated a statistically significant association between PET findings and event‐free survival (P = .0001) and overall survival (P = .0001).CONCLUSIONS:
The results of this study indicated that midtreatment PET may represent a significant step forward in helping physicians make crucial decisions on further treatment. Cancer 2011. © 2010 American Cancer Society. 相似文献10.

While various tools such as the International Prognostic Index (IPI) and its derivatives exist for risk-stratification of diffuse large B-cell lymphoma (DLBCL) at diagnosis, patient and disease characteristics capable of predicting outcome after high-dose chemotherapy followed by autologous stem cell transplantation (HDC/ASCT) are not clearly defined. We retrospectively analyzed medical records of 111 DLBCL patients (78 relapsed and 33 refractory) who underwent HDC/ASCT at our institution from 2010-2015. After a median follow-up time of 4.6 years (interquartile range [IQR] 2.2-8.1), the likelihood of 5-year progression-free survival (PFS) was 62.2% (95% CI, 53.4%-72.4%) and the likelihood of 5-year overall survival (OS) was 68.9% (95% CI, 60.7%-78.2%). More than three chemotherapy regimens prior to ASCT was the only variable associated with lower likelihood of PFS (P = .004) and OS (P = 0.026). Male gender and high IPI score at time of ASCT were also associated with lower likelihood of PFS (P = .043; P = .013). NCCN IPI and age-adjusted IPI at time of ASCT were not predictive of outcome following ASCT. Patients with refractory and relapsed disease had similar outcomes post-ASCT (P = .207 for PFS, P = .073 for OS). 相似文献

BACKGROUND:
Autologous stem cell transplantation (autoSCT) has improved the outcome of patients with mantle cell lymphoma (MCL) considerably. However, little is known about the patterns and outcome of MCL recurrence after autoSCT.METHODS:
The authors conducted a retrospective study of 118 patients with MCL who underwent autoSCT from August 1992 to August 2008 at 3 different referral centers in Germany.RESULTS:
Fifty‐two relapses occurred for a cumulative incidence of 46% after 5 years. Only 3 patients relapsed after 5 years (at 90 months, 91 months, and 171 months) after undergoing autoSCT. A Cox regression analysis of the incidence of relapse identified not receiving rituximab before autoSCT and undergoing salvage autoSCT as predictive factors for relapse, whereas cytosine arabinoside intensification; a total body irradiation‐based, high‐dose regimen; patient age; and year of transplantation had no influence. The median overall survival (OS) after relapse was 23 months. Twenty patients (39%) underwent allogeneic stem cell transplantation (alloSCT) for relapse, and 11 of those patients remained in ongoing complete remission at the time of the current report. It is noteworthy that there were 4 long‐term survivors who lived for >5 years after relapse even without undergoing alloSCT. A Cox regression analysis of OS after relapse revealed that the response duration after autoSCT was an adverse predictor of OS, whereas alloSCT was associated with a significantly longer OS after relapse.CONCLUSIONS:
The current results indicated that autoSCT was capable of inducing long‐term remission up to 16 years after treatment, but the outcome of patients with MCL who relapsed after autoSCT was poor, especially if their response duration after autoSCT was short. However, for a subset of patients with relapsed MCL, alloSCT may offer the possibility of durable survival, and individual patients can enjoy long‐term survival after relapse even without undergoing alloSCT.

We conducted a retrospective study to evaluate the clinical impact of an early recovery of posttransplant absolute lymphocyte count (ALC) on the outcome of frontline autologous stem cell transplantation (ASCT) for diffuse large B‐cell lymphoma (DLBCL). We reviewed 65 DLBCL patients who underwent frontline ASCT after primary chemotherapy based on cyclophosphamide, doxorubicin, vincristine, and prednisone. A receiver operating characteristic analysis was performed to determine the optimal cut point (0.4 × 109/L) for an ALC at 15 days after ASCT (ALC‐15). Both event‐free survival and overall survival rates of the higher‐ALC‐15 group were significantly better than those of the lower‐ALC‐15 group (event‐free survival, P = .008; overall survival, P = .013). The infused CD34+ cell count was significantly associated with the recovery of ALC‐15 (>0.4 × 109/L) after ASCT (P = .028). A multivariate analysis confirmed that a higher infused CD34+ cell dose (>5.0 × 106 cells/kg) was an independent factor affecting an early recovery of ALC after ASCT (odds ratio, 4.145; 95% confidence interval, 1.106‐15.528; P = .035). In conclusion, an early recovery of ALC after ASCT can be regarded as a good prognostic marker in patients with DLBCL who have undergone frontline ASCT. We found that the infused CD34+ cell dose for ASCT was associated with the recovery of ALC. 相似文献

The aim of the present study was to investigate the feasibility of measuring metabolic tumor burden using [F‐18] fluorodeoxyglucose (18F‐FDG) positron emission tomography/computed tomography (PET/CT) in patients with relapsed or refractory diffuse large B‐cell lymphoma (DLBCL) treated with bendamustine–rituximab. Because the standardized uptake value is a critical parameter of tumor characterization, we carried out a phantom study of 18F‐FDG PET/CT to ensure quality control for 28 machines in the 24 institutions (Japan, 17 institutions; Korea, 7 institutions) participating in our clinical study. Fifty‐five patients with relapsed or refractory DLBCL were enrolled. The 18F‐FDG PET/CT was acquired before treatment, after two cycles, and after the last treatment cycle. Treatment response was assessed after two cycles and after the last cycle using the Lugano classification. Using this classification, remission was complete in 15 patients (27%) and incomplete in 40 patients (73%) after two cycles of therapy, and remission was complete in 32 patients (58%) and incomplete in 23 patients (42%) after the last treatment cycle. The percentage change in all PET/CT parameters except for the area under the curve of the cumulative standardized uptake value–volume histogram was significantly greater in complete response patients than in non‐complete response patients after two cycles and the last cycle. The Cox proportional hazard model and best subset selection method revealed that the percentage change of the sum of total lesion glycolysis after the last cycle (relative risk, 5.24; P = 0.003) was an independent predictor of progression‐free survival. The percent change of sum of total lesion glycolysis, calculated from PET/CT, can be used to quantify the response to treatment and can predict progression‐free survival after the last treatment cycle in patients with relapsed or refractory DLBCL treated with bendamustine–rituximab. 相似文献

High‐dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a recognized treatment option for patients with relapsed diffuse large B‐cell lymphoma. We have analysed 51 patients who underwent ASCT after LACE (lomustine (CCNU), cytarabine (Ara‐C), cyclophosphamide, etoposide) conditioning for relapsed (n = 34, 67%) or primary refractory (n = 17, 33%) diffuse large B‐cell lymphoma. With a median follow‐up of 60 months (range 2–216) the probabilities of overall survival (OS) and progression‐free survival (PFS) at 5 years were 47 and 42%, respectively. The cumulative treatment‐related mortality was 10% (n = 5). Probabilities for OS and PFS at 5 years were 56 and 50% for patients with chemosensitive and 29 and 27% for patients with chemorefractory disease. In multivariate analysis abnormal pre‐ASCT levels of C‐reactive protein (>5 mg/L) were identified as a risk factor for worse OS, whereas abnormal pre‐ASCT levels of C‐reactive protein and chemoresistance predicted inferior PFS. LACE followed by ASCT is an effective treatment for approximately half of patients with chemosensitive relapsed diffuse large B‐cell lymphoma, and a proportion of chemorefractory patients also benefit.

The prognosis of diffuse large B‐cell lymphoma (DLBCL) having MYC rearrangement (MYC‐R), including double hit lymphoma (DHL), is poor by standard immunochemotherapy. To evaluate the significance of hematopoietic stem cell transplantation (SCT) for DLBCL with MYC‐R, we retrospectively analyzed Japanese SCT registry data. In total, 54 patients with DLBCL with MYC‐R were identified from 4336 registered adult DLBCL patients. Detailed clinical and cytogenetic information was obtained for 48 patients. The median age at diagnosis of the 48 patients was 54.5 (range 21–67) years. Twenty‐six (54%) patients had MYC‐R only (single hit), and 22 (46%) had MYC‐R and BCL2, and/or BCL6 rearrangement (double/triple hit). In 12 patients who received auto‐SCT during the first complete response (CR), both the 2‐year overall survival (OS) and progression‐free survival (PFS) rates were 75.0% (95% confidence interval [CI], 40.8%–91.2%). In 20 patients who received auto‐SCT after relapsed or refractory state, the 2‐year OS and PFS rates were 68.2% (95% CI, 41.9%–84.5%) and 59.6% (95% CI, 35.1%–77.4%), respectively. In 17 patients who received allo‐SCT, only 4 patients underwent SCT in CR. The 2‐year OS and PFS rates were 29.4% (95% CI, 10.7%–51.1%) and 17.6% (95% CI, 4.3%–38.3%), respectively. The rate of non‐relapse mortality at 1 year was 41.2% (95% CI, 17.1%–64.0%) in this group. The outcomes of single hit and double or triple hit were not different. These findings suggest that auto‐SCT may be effective for MYC‐R DLBCL, including DHL patients of chemosensitive relapsed or refractory state. Since most patients received allo‐SCT not in CR, the outcome of allo‐SCT was unsatisfactory due to high non‐relapse mortality and early relapse. To clarify the role of allo‐SCT for MYC‐R DLBCL, further accumulation of patients is necessary. 相似文献

Given the excellent results obtained with present new induction regimens in PMBL, the role of frontline ASCT is controversial. We present 71 patients with PMBL receiving induction chemotherapy, followed by ASCT as frontline therapy from the GEL-TAMO registry. Most patients presented with high-risk clinical features. At transplant, 49% of patients were in CR, 32% in PR and 18% failed induction therapy; 53% received radiotherapy. After the transplant 75% of patients achieved CR. With a median follow-up of 52.5 months, the OS, PFS and DFS at 4 years from diagnosis were, respectively, 84%, 81% and 81% for the first CR patients and 49%, 42% and 82% for the induction failure (PR and refractory) patients. Disease progression was the main cause of death (79%). By multivariate survival analysis the tumour score, refractory disease at transplant and radiotherapy were independent variables associated with OS and PFS. Our experience, with a prolonged follow-up, shows that patients with PMBL presenting at diagnosis with high-risk features or PR response to induction therapy have an encouraging survival with frontline ASCT. However, patients who received the transplant after failing the induction regimen have a very poor prognosis and should be tested with other innovative approaches. Finally, only a randomized trial could prove the value of ASCT as frontline therapy and also must be considered that addition to Rituximab to induction treatments could make ASCT unnecessary. 相似文献
