Intensive Induction Chemotherapy Followed by Early High-Dose Therapy and Hematopoietic Stem Cell Transplantation Results in Improved Outcome for Patients with Hepatosplenic T-Cell Lymphoma: A Single Institution Experience
AbstractIntroductionHepatosplenic T-cell lymphoma is a rare form of extranodal non-Hodgkin lymphoma, first recognized as a distinct entity in the Revised European-American Lymphoma classification. Typical presentation includes lymphomatous infiltration of spleen and liver, and peripheral lymphadenopathy is rarely seen. The prognosis is almost uniformly poor, and there are no prospective studies of treatment of HSTCL.Patients and MethodsFor this report, we conducted a retrospective review of all pts who underwent treatment for HSTCL at our institution. Individual chart review was performed to report clinical presentation, management, and outcome.ResultsWe identified 14 pts with HSTCL managed at our center, 7 of which remain alive with median follow-up of 65.6 months. Six of 7 received alternative induction chemotherapy regimens such as ICE (ifosfamide, carboplatin, etoposide) or IVAC (ifosfamide, etoposide, high-dose cytarabine) as opposed to CHOP and all surviving pts had proceeded to undergo either autologous or allogeneic SCT.ConclusionOur results suggest that use of non-CHOP induction regimen and early use of high dose therapy and SCT consolidation may translate to improved survival for pts with HSTCL

Pretransplantation functional imaging predicts outcome following autologous stem cell transplantation for relapsed and refractory Hodgkin lymphoma
To identify prognostic factors for patients transplanted for relapsed or refractory Hodgkin lymphoma we carried out a combined analysis of patients followed prospectively on 3 consecutive protocols at Memorial Sloan-Kettering Cancer Center. One hundred fifty-three patients with chemosensitive disease after ICE (ifosfamide, carboplatin, and etoposide)–based salvage therapy (ST) proceeded to high-dose chemoradiotherapy followed by autologous stem cell transplantation (ASCT). Patients were evaluated with computed tomography and functional imaging (gallium or fluorodeoxyglucose-positron emission tomography) prior to ST and again before ASCT. Functional imaging status before ASCT was the only factor significant for event-free survival (EFS) and overall survival by multivariate analysis and clearly identifies poor risk patients (5-year EFS 31% and 75% for FI-positive and negative patients respectively). Administration of involved-field radiotherapy with ASCT was marginally significant for EFS (

Pre-Transplant Evaluation with Both CT and PET Following Second-Line Therapy Is Essential for Predicting Outcome in Patients with Transplant- Eligible Relapsed and Primary Refractory Hodgkin Lymphoma
Abstract
The standard treatment for relapsed and primary refractory (rel/ref) Hodgkin lymphoma (HL) for patients (pts) who demonstrate chemosensitivity to second-line chemotherapy (ST) is high dose chemotherapy followed by autologous stem cell transplantation (HDT-ASCT). Since 1994, four studies at our institution evaluated ICE (ifosfamide, carboplatin, and etoposide) based salvage therapy followed by HDT-ASCT in rel/ref HL. Chemosensitivity is a requirement for pts to proceed to HDT-ASCT, however the definition of chemosensitivity is broad. We use both functional imaging (gallium or PET) and CT to assess response to ICE; pts with chemosensitive disease fall into three groups: normalization of CT and FI (NRM), residual mass on CT but with negative FI (RM, FI-), and FI positivity regardless of CT finding (FI+). Here we report the outcome for pts who responded to ICE ST and proceeded to HDT-ASCT.
Between October 1994 and February 2008, 198 pts received ICE on 1 of 4 consecutive protocols (169 pts) or as per protocol (29 pts) and were deemed transplant-eligible. The median follow-up for surviving patients is 7.4 years. There were 99 male pts and 99 female pts; the median age was 31. With respect to the 3 pre-salvage chemotherapy risk factors (RF) (relapse within 1 year of primary treatment, presence of extranodal disease, and B symptoms): 44 pts had 0 RF, 64 had 1 RF, 75 had 2 RF, and 8 had 3 RF. Bulky disease defined as greater than 5cm or 10cm was present in 60 (30%) and 15 (7.5%) pts respectively.
The five year event free survival (EFS) and overall survival (OS) were 69% and 78% respectively. Seventy six (38%) had a NRM response to ST, 73 (37%) had a RM, FI- response, and 49 (25%) were FI+. The 5 year EFS and OS for the three groups were 86% and 93%, 71% and 79%, and 41% and 51% respectively. There was a statistically significant improvement in OS and EFS for the NRM and RM, FI- groups compared to the FI+ group (p<0.0001). Surprisingly, a comparison between the NRM and RM, FI- groups also revealed a statistically significant improvement in EFS and OS for the NRM group (p=0.05 and 0.04 respectively).
Response to ICE ST followed by HDT-ASCT is associated with a prolonged EFS and OS. The quality of response to ICE ST had a significant impact on outcome. Both a residual mass with normalized FI and abnormal FI after ST predicts for an inferior outcome following HDT-ASCT. However, residual radiotracer on FI was associated with the poorest outcome in both EFS and OS.
CONCLUSION: Outcome cannot be predicted by FI alone since both RM, FI- and FI+ groups had an inferior outcome compared to NRM. The most accurate post treatment evaluation includes both CT and PET.

Normalization of FDG-PET Pre-ASCT with Additional Non-Cross Resistant Chemotherapy Improves EFS in Patients with Relapsed and Primary Refractory Hodgkin Lymphoma-Memorial Sloan Kettering Protocol 04-047
Abstract
We have reported that outcome of transplant-eligible patients (pts) with relapsed and primary refractory HL is determined by three pre-second-line chemotherapy (ST) risk factors (RF): remission duration of <1 yr., extranodal disease and B symptoms. In addition, normalization of FDG-PET prior to ASCT is the most important factor predicting favorable EFS. We now report the preliminary results of an ongoing phase II risk-adapted study where HL pts receive the following: Favorable risk (0–1 RF) - one cycle of standard dose ifosfamide, carboplatin and etoposide (ICE) ST followed by one cycle of augmented ICE; unfavorable risk (2-RF)- 2 cycles of augmented ICE. All pts then underwent a restaging FDG-PET and the results determined the next treatment. Pts with a negative FDG-PET went directly to HDT/ASCT; however if the FDG-PET was still positive, pts received an additional four biweekly cycles of gemcitabine (1000 mg/m2), vinorelbine (20 mg/m2) and liposomal doxorubicin (15 mg/m2) (GVD) followed by repeat FDG-PET scan; pts without evidence of progression then received HDT/ASCT. Preceding high-dose chemotherapy and ASCT, patients that were radiation therapy-naive received involved field radiotherapy (IFRT) followed by total lymphoid irradiation. Selected previously irradiated patients received only IFRT.
Sixty-two pts are evaluable; median follow-up of surviving pts is 30 months; median age was 35. Forty-eight pts had a remission duration of < 1 yr. of those, 28 had primary refractory disease; 28 had extranodal disease and 11 had B symptoms. All patients had previously failed doxorubicin-based chemotherapy; 18 had received prior radiation; of those, 13 failed in the radiation field.
Following first ST chemotherapy with ICE, 3 pts progressed, while 37 pts normalized their FDG-PET scan and currently 31 of these pts are event-free. Twenty-five pts with an improving CT scan after ICE still had a persistently positive FDG-PET; they received the second ST with GVD. Of these, 13 pts normalized their FDG-PET scan and 11 are eventfree; the remaining 12 pts had persistently abnormal FDG-PET scan or progressed; only 4 of them are event-free. There was no difference in outcome between the pts who had normal FDG-PET after ICE (pre-ASCT) and those who achieved a negative FDG-PET scan because of the additional ST with GVD. Both of these cohorts had a statistically significant improvement in EFS compared to pts with a persistently positive FDG-PET. In total 46/62 (65%) pts on this program are currently event-free. One pt died from sepsis. Conclusion: For pts with relapsed and primary refractory HL our evolving strategy is to administer ST until normalization of FDG-PET is achieved prior to HDT/ASCT.

Normalization of pre-ASCT, FDG-PET imaging with second-line, non–cross-resistant, chemotherapy programs improves event-free survival in patients with Hodgkin lymphoma
We previously reported that remission duration < 1 year, extranodal disease, and B symptoms before salvage chemotherapy (SLT) can stratify relapsed or refractory Hodgkin lymphoma (HL) patients into favorable and unfavorable cohorts. In addition, pre-autologous stem cell transplant (ASCT)

FDG-PET response to SLT predicts outcome. This phase 2 study uses both pre-SLT prognostic factors and post-SLT FDG-PET response in a risk-adapted approach to improve PFS after high-dose radio-chemotherapy (HDT) and ASCT. The first SLT uses 2 cycles of ICE in a standard or augmented dose (ICE/aICE), followed by restaging FDG-PET scan. Patients with a negative scan received a transplant. If the FDG-PET scan remained positive, patients received 4 biweekly doses of gemcitabine, vinorelbine, and liposomal doxorubicin. Patients without evidence of disease progression proceeded to HDT/ASCT; those with progressive disease were study failures. At a median follow-up of 51 months, EFS analyzed by intent to treat as well as for transplanted patients is 70% and 79%, respectively. Patients transplanted with negative FDG-PET, pre-HDT/ASCT after 1 or 2 SLT programs, had an EFS of > 80%, versus 28.6% for patients with a positive scan (
P
< .001). This prospective study provides evidence that the goal of SLT in patients with Hodgkin lymphoma should be a negative FDG-PET scan before HDT/ASCT. The study was registered at

Primary Breast Diffuse Large B Cell Lymphoma: A Distinct Clinical Entity
Abstract Abstract 1618 Introduction: Primary breast lymphoma is a rare type of non-Hodgkin lymphoma (NHL), representing about 1% of breast tumors and 2% of extranodal NHL. Diffuse large B-cell lymphoma (DLBCL) is the most common primary subtype presenting in the breast. Due to the low incidence of primary breast DLBCL, outcome data is limited. The aim of this study was to retrospectively assess the natural history of primary breast DLBCL in the pre and post rituximab eras, with specific emphasis on the incidence of local, systemic and central nervous system (CNS) relapses. Methods: Data was retrospectively collected on patients with primary breast DLBCL from seven USA academic medical centers. Institutional review board approval was obtained at each participating site. Patients were identified through institutional databases and tumor registries at each site. Charts were reviewed to obtain demographic and clinical variables including treatment history and dates of relapse and death when applicable. Only patients with stage I/II disease (involvement of breast and localized lymph nodes) were included. All histologies apart from primary DLBCL were excluded. Overall survival (OS) was calculated from the diagnosis date to the date of death or last follow-up. Time to Progression (TTP) was calculated from diagnosis data until the date of pathological evidence of recurrence or death. Data were summarized using descriptive statistics, and survival was analyzed using the Kaplan-Meier method. Results: Between 1984 and 2012, 75 patients were identified who met the eligibility criteria. The median age was 62 years (range 17–87); 81% presented with a palpable mass; 12% had their disease detected incidentally by mammography; 4% presented with B-symptoms; 59% had right breast involvement; 67% had stage I and 33% had stage II disease. The stage-adjusted international prognostic index (IPI) score was 0 in 28% of patients, 1 in 41%, 2, in 25%, 3 in 4% and 4 in 1%. 91% of patients were treated with chemotherapy; 31% of these were treated in the pre-rituximab era and 69% received rituximab. Radiation therapy (RT) was utilized in 68% of patients and was the only treatment modality in 8% of those receiving RT. 8% of patients received CNS prophylaxis with intrathecal chemotherapy. After a median follow-up of 4.5 years (range 0.6 – 20.6 years), the Kaplan-Meier estimated median TTP was 10.4 years (95% CI 6.2 – 14.6 years) and the median OS was 14.6 years (95% CI 6.5 – 22.6 years). The 5-year TTP and 5-year OS were 65% (95% CI 53–77%) and 75% (95% CI 64–86%) respectively. Among the patients who relapsed, 67% occurred within the first 2 years. A total of 7 relapses in the breast were observed, none in patients treated with combination of chemotherapy and RT. In univariate analysis, rituximab exposure was not associated with any difference in TTP or OS. The stage-adjusted IPI was associated with OS; the 5-year OS was 88% (95% CI 79–98%) in patients with a score of 0–1 versus 48% (95% CI 25–71%) in those with a score of 2–4 (log rank p < 0.001). The very limited-disease group with a stage-adjusted IPI of 0 had a 5-year OS of 94% (95% CI 83–100%) compared to all others who had a 5-year OS of 67% (95% CI 52–81%; log rank p = 0.001). There was no difference in TTP and OS in patients with solitary versus multiple breast masses or between patients with tumors less than versus more than 7cm. Patients receiving RT in addition to chemotherapy had a longer TTP than those who did not (log rank p = 0.03), but RT was not associated with an improved OS. Patients who relapsed and underwent stem cell transplant (SCT) had similar OS to those who never relapsed. Ten patients (13%) had CNS relapse (3 with leptomeningeal disease, 5 with brain parenchymal disease and 2 with both). All CNS relapses occurred within the first 2.8 years from the time of diagnosis. There was no difference in the rate of CNS relapse in the patients who received IT prophylaxis versus those who did not. Conclusions: In this multicenter study, the largest published to date, primary breast DLBCL appears to have a worse prognosis than early-stage DLBCL in nodal or other extranodal sites. RT was associated with improved TTP. Patients who relapsed were successfully salvaged with SCT, and had similar survival times to those who never relapsed. A high CNS relapse rate (∼1 in 8 patients, including parenchymal disease in 70%) was observed. The small numbers preclude definitive conclusions on the value of intrathecal prophylaxis or the utility of rituximab. Disclosures: No relevant conflicts of interest to declare
