Microabstract
High-dose chemotherapy (HDCT) with autologous stem cell transplantation (aSCT) is a standard therapy for patients with metastatic germ cell tumors relapsing after first-line platinum-based chemotherapy. Clinically meaningful improvements in stem cell mobilization techniques and high-dose chemotherapy toxicity are noted with changes in therapy over the last two decades.
Abstract
Background
High-dose chemotherapy (HDCT) with autologous stem cell transplantation (aSCT) has been a standard therapy for relapsed metastatic germ cell tumors (GCTs) over the last two decades, but there have been many changes in practice over time with respect to stem cell source, mobilization and conditioning regimens. Mobilization is impaired with greater cisplatin exposure.
Patients and Methods
Patients with relapsed GCT who received HDCT/aSCT at Dana-Farber Cancer Institute between 1997- 2017 were identified. Diagnosis, first-line chemotherapy, stem cell mobilization, HDCT, toxicity and survival outcomes was annotated and descriptively summarized. Univariable associations of clinicopathologic features and relapse and survival were assessed. Time-to-event analyses were performed by HDCT type and duration.
Results
Thirty-five eligible patients were identified. TIP was the most common regimen prior to HDCT and resulted in a high rate of successful initial mobilization (95%). Ten (29%) patients were mobilized with filgrastim and plerixafor (CXCR4 antagonist). All plerixafor-treated patients were mobilized with sufficient cells for two transplants. Oxazaphosphorine (cyclophosphamide or ifosfamide)-containing (O-C) HDCT was employed between 1997-2008 and subsequent patients were treated with high-dose carboplatin plus etoposide (CE). O-C HDCT was associated with excessive cardiac (33%), severe liver (45%) and renal dysfunction compared to CE. Two O-C-treated patients died of drug-related lung toxicity. Fifty-one percent of the cohort had relapsed and 46% had died.
Conclusions
Plerixafor has a role in stem cell mobilization and aSCT for relapsed GCT when cisplatin in bridging prior to HDC may be problematic. O-C and CE HDCT regimens have differing toxicity patterns that are clinically meaningful.
Introduction
While germ cell tumors (GCTs) are considered the paradigm of a curable adult solid organ malignancy even in the presence of disseminated disease1 , some men with metastatic GCT will relapse following first-line platinum-based chemotherapy2 . Salvage systemic therapy approaches have evolved over decades and have led to the adoption of conventional-dose chemotherapy3,4 (CDCT) and/or high-dose chemotherapy (HDCT) followed by tandem autologous stem cell transplantation5,6 (aSCT) as potentially curative treatment options. In modern HDCT cohorts, with improvements in ancillary and supportive care, durable disease remission can be achieved in about in 50-60% of patients who are treated with HDCT7,8 – with outcomes varying by presence of adverse prognostic features prior to transplantation.
Standard conditioning HDCT regimens have largely been informed by high-volume single institution experiences. The outcomes of these various regimens have been reported in single-center, non-comparative studies. These include evaluation of higher dosing, additional cycles, ‘bridging’ salvage regimens and alternative treatment sequencing9. Studies have assessed agents additional to high-dose carboplatin plus etoposide (CE) first established at Indiana University10. One prospective, randomized German trial compared one cycle of cisplatin, etoposide and ifosfamide (VIP) plus three cycles of sequential high-dose CE versus three cycles of VIP plus a single cycle of very high-dose carboplatin, etoposide and cyclophosphamide (CEC)11. The study was terminated early due to excess treatment-related mortality (TRM) (16%) in the CEC arm caused by sepsis, hemorrhage and cardiotoxicity, as well occurrence of more frequent Grade 3-4 organ (cardiac, hepatic and neurologic) dysfunction. Furthermore, in long-term follow-up, a trend to superior overall survival was demonstrated with sequential CE due to fewer toxic deaths12. This trial highlighted the notion that in the absence of unequivocal benefit, use of HDCT agents in addition to CE, may only be resulting in excessive toxicity and/or death. The effects of other commonly-adopted practices such as the use of bridging therapy with contemporary salvage chemotherapy and newer adjunct agents for stem cell collection remain less clear. The CE regimen alone is associated with a 2-year progression-free and overall survival of 60- 66%7. Even in the third-line setting, nearly half of CE-treated patients will achieve durable disease control. These results are comparable to long-term outcomes of the TI-CE (paclitaxel, ifosfamide plus high-dose carboplatin, etoposide) regimen, which was trialed in patients with unfavorable prognostic features such as extragonadal primary site and incomplete response to first-line chemotherapy8. This regimen adopted TI (instead of TIP; paclitaxel, ifosfamide, cisplatin) due to concern that TIP resulted in inferior stem cell mobilization prior to CE. Whether HDCT is superior to CDCT as initial salvage therapy is being investigated in the prospective TIGER trial (NCT02375204).Recognizing the evolution of aSCT for GCT over the last 30 years, we reviewed the outcomes of HDCT and aSCT at Dana-Farber Cancer Institute (DFCI) between 1997 and 2017, with a focus on change of HDCT regimen from CEC and the use of modern stem cell mobilization techniques with TIP salvage therapy and adjunct mobilization agents.
Methods
The DFCI bone marrow transplant patient database was used to identify a cohort of patients with relapsed metastatic GCT of gonadal and extra-gonadal primary who were consecutively-treated with HDCT between 1997 and 2017 (n = 37). Patients treated with HDCT as first-line therapy for metastatic GCT were excluded (n = 2). The study population for this analysis thus included 35 individual patients.
Demographics, cancer features (primary site, primary histology, AJCC stage, IGCCC risk category [International Germ Cell Consensus Classification]), first-line treatment (chemotherapy type and cycle, response, post-chemotherapy surgery) and relapse (date, tumor markers and sites of metastasis) variables were collected from the electronic medical record. We categorized HDCT type into oxazaphosporine-containing (O-C) and CE regimens. We collected data to calculate Einhorn risk score (defined as 2 points each for IGCCCG high risk stage and platinum refractoriness; 3 points for third-line of subsequent chemotherapy) and Beyer risk score (defined as 1 point for platinum-refractory or absolute platinum-refractory disease; 2 points each for primary mediastinal tumor and for hCG level ≥1000 IU/liter).
Platinum refractory was defined as radiological, biochemical and/or clinical progression within 4 weeks of treatment with cisplatin prior to transplantation. Absolutely-refractory was no response to initial platinum-based chemotherapy5 . Salvage chemotherapy, HDCT and transplantation variables were detailed, including stem cell mobilization and collection metrics. Our primary outcome of interest was relapse after aSCT, defined as unequivocal disease progression evidenced by rising tumor markers, radiological and/or clinical progression.Dates of relapse, death and last follow-up were captured at the completion of the follow-up period (31 Dec 2017). Finally, we reviewed HDCT/aSCT toxicity documentation in the medical records with parallel referencing of laboratory reports from the date of first dose of HDCT to one month after last stem cell infusion and grading reported per CTCAE v4.0.
Patient and treatment characteristics were summarized descriptively. We utilized Cox proportional hazards regression models to calculate hazard ratios and 95% confidence intervals (95% CIs) to estimate the univariable association between HDCT regimen and relapse and overall survival.Similarly, we also evaluated the univariable association between other clinical characteristics, including histology, IGCCCG, Einhorn and Beyer risk categories, platinum sensitivity, and line of therapy, and outcomes of relapse and death. We estimated overall survival by Einhorn risk category, HDCT early life infections regimen, and number of HDCT cycles using Kaplan-Meier curves. All p-values were two-sided with significance level of 0.05. All statistical analyses were completed using SAS v 9.4. The study was approved by the Institutional Review Board at the Dana-Farber Cancer Institute.
Results
Patient Characteristics
Baseline patient and treatment characteristics are summarized in Table 1. Twenty-nine (83%) testicular GCT and 6 (17%) extragonadal GCT patients underwent transplantation. The majority of patients had non-seminomatous primary histology (74%) and received HDCT as second line therapy (first salvage systemic therapy) (86%) and the remaining 14% received HDCT as third-line treatment. The IGCCC risk classification at time of first metastatic disease was 31% low, 26% intermediate and 40% high. At relapse prior to HDCT/aSCT, 77% of patients were platinum-sensitive and 23% were platinum- refractory. Twenty-one (60%) patients had non-pulmonary visceral metastases. All but one patient received bridging platinum chemotherapy prior to stem cell mobilization (median number of cycles: 2; range: 1 to 4) and TIP (paclitaxel, ifosfamide, cisplatin) was the most commonly administered regimen (60%) followed by VeIP (vinblastine, ifosfamide, cisplatin) in 17%. Distribution of Einhorn risk category at time of HDCT was 40% low, 43% intermediate and 17% high.
Stem cell mobilization and collection
Successful peripheral blood stem cell collection was achieved in 32 (91%) patients and 3 underwent bone marrow harvest. Ten (29%) patients were treated with plerixafor (a CXCR4 antagonist FDA- approved for use in combination with G-CSF in aSCT for non-Hodgkin lymphoma and multiple myeloma13,14) in the mobilization phase (Table 2). Of these patients, 3 were administered plerixafor after poor mobilization with G-CSF alone (median number of apheresis before plerixafor = 3) and all achieved adequate stem cell count with subsequent collection. Patients treated with G-CSF plus plerixafor upfront (prior to first apheresis) based on peripheral blood absolute CD34 count <10 cells/microliter on day 4 of G-CSF (n = 7) achieved a median cell count of 6.1 x 106 CD34+ cells/kg after a median of 2 apheresis days, and all achieved a target stem cell count deemed adequate to proceed directly to conditioning chemotherapy. Of the plerixafor-treated patients who did not proceed to a second cycle Tissue biopsy of HDCT/aSCT (n = 6), none were due to inadequate stem cell count. In contrast, 29% (4/14) of the patients who were treated with G-CSF alone and did not proceed to a second transplant did so due to insufficient cells. Of the 21 patients who received TIP with a median of 2 cycles administered (range: 1 to 4), one patient required adjunct plerixafor for poor mobilization (with subsequent adequate cell count) and none required bone marrow harvest. No TIP-treated patients who received one transplant only did so due to inadequate cells for a second transplant.
High-dose chemotherapy and autologous transplantation
Oxazaphosphorine-containing (O-C) HDCT regimens such as cyclophosphamide or ifosfamide (CCE, n = 11; ICE: ifosfamide, carboplatin, etoposide, n = 2; CC: cyclophosphamide, carboplatin, n = 2) were administered between 1997 and 2008. All patients in subsequent years (n = 20) received CE. Chemotherapy doses and schedules are detailed in Supplementary Table 1. Of 32 patients planned for 2 sequential cycles of HDCT/aSCT, only 15 (47%) received a second transplant and this was due to: toxicity (n = 8; 3 with O-C and 5 with CE), treatment-related death (n = 2; all O-C), inadequate stem cells (n = 4; all O-C), disease progression (n = 2) and non-compliance (n = 1).
Toxicity and treatment-related mortality (TRM)
Selected toxicities contrasting O-C and CE regimens are presented in Table 3. Neutropenic fever was nearly universal, however clinically-proven infection was more common in the O-C group than the CE group (40% vs 10%). O-C HDCT was associated with more cardiac, liver and renal dysfunction. Acute, drug-related cardiotoxicity was unique among O-C patients (33%, versus 0% in CE). Fourteen of 15 (93%) O-C patients had Grade 3 (73%) or Grade 4 (20%) transaminitis, versus 9/20 (45%) CE patients.Eleven of 15 (73%) O-C patients experienced any degree of renal dysfunction, versus 9/20 (45%, all Grade 1-2 events) CE patients. One patient in the O-C group had Grade 3 nephropathy (creatinine 3 to 6 times upper limit of normal). Overall TRM in the cohort was 5.7% with two O-C treated patients dying from acute, fatal lung toxicity and no treatment-related deaths in CE treated patients.
Relapse and survival
At the completion of the follow-up period, 18/35 (51%) patients had relapsed at a median of 3 months after first dose of HDCT and 16/36 (46%) had died, at a median of 7.4 months. Median follow-up time in patients who had not died was 7.2 years. Univariable associations of clinical characteristics and relapse and death are presented in Table 4.There was not a statistically significant difference in relapse or survival by HDCT regimen. A trend of increased risk of relapse and death was observed in intermediate/poor Einhorn risk (versus good risk; Fig 1a) and intermediate/poor initial IGCCC risk (versus good risk) patients. We found no significant association of O-C HDCT (Fig 1a) or number of cycles of HDCT (Fig 1c) and overall survival.
Discussion
The optimal management of relapsed germ cell tumors has not been defined due to a paucity of prospective randomized clinical trials. We leveraged a cohort of relapsed GCT patients who underwent aSCT at our referral transplantation center to investigate differential treatment, toxicity and disease outcomes with the evolution of aSCT practice patterns over time. In doing so, we noted informative changes in (i) stem cell mobilization and (ii) high-dose chemotherapy toxicity.
Successful stem cell mobilization for peripheral blood collection was observed in both platinum- sensitive and resistant patients treated with bridging chemotherapy (most treated with TIP for median 2 cycles), confirming this is a reasonable strategy to cytoreduce patients prior to high-dose chemotherapy without compromising the success of mobilization. Indeed, a similar approach has been successfully adopted at Indiana University, using conventional-dose vinblastine, ifosfamide and cisplatin in platinum- sensitive patients5. In a phase II study15 , Rick and colleagues demonstrated a favorable response rate of 69% with 3 cycles of conventional-dose TIP prior to HDCT, however 29% of patients required an additional cycle of paclitaxel plus ifosfamide due to poor stem cell mobilization – an observation which prompted concerns regarding the efficacy of TIP to aid adequate mobilization. In practice, delivery of active standard-dose salvage chemotherapy prior to arranging HDCT and stem cell rescue is necessary in patients who present with symptomatic or gross disease progression, or where a significant delay to HDCT is predicted (such as obtaining insurance approval). Our findings do not demonstrate a detrimental impact with use of TIP on subsequent stem cell mobilization in this setting. It should be noted that while this strategy was observed to be feasible in some platinum-refractory patients, the majority (77%) of patients in the cohort were platinum-sensitive and this likely contributed to the ability to stabilize disease with TIP and successfully mobilize stem cells prior to HDCT.
We confirm previous reports of successful remobilization and subsequent engraftment with use of plerixafor plus G-CSF in refractory, pre-treated GCT patients who experienced poor
mobilization with G-CSF alone16-18 , including TIP-supported mobilization19. In contrast, 4 of the 14 patients who were mobilized with G-CSF alone and had a single transplant did so due to insufficient cells to support a second transplant, which suggests that incorporation of plerixafor in mobilization regimens should be strongly considered for poor-mobilizers to support the optimal delivery of potentially curative treatment. At our institution plerixafor has been adopted for as an adjunct mobilization agent in GCT patients if the blood absolute CD34 count on the fourth day of G-CSF (10mcg/kg/d) is below 10 cells/microliter, and this approach has also been reported by other investigators20 , however notably plerixafor is not currently FDA-approved for stem cell mobilization in GCT.
The excessive toxicity and treatment-associated deaths observed with high-dose O-C regimens in our cohort supports caution in use, within the limitations selleck of this retrospective series. CEC was first established as an active and efficacious regimen with a reported complete response rate of 40%21. The most frequent severe non-hematological toxicities were nephropathy (10% rate of creatinine elevation >4 mg/dL or BUN > 75 mg/dL) and liver dysfunction (20% rate of Grade 3 liver enzyme elevation). Similarly, studies of high-dose ICE have demonstrated renal and liver dysfunction as the most frequently occurring toxicities22-24 . Our cohort is notable for the exceedingly high rate of severe hepatotoxicity in comparison to historical studies of three-drug O-C HDCT, however, all instances were transient and resolved without specific intervention nor long-term sequelae. The high rate of cardiotoxicity observed uniquely in the O-C cohort, likely related to high-dose cyclophosphamide25 , is of major concern for both the impeding of administering a second cycle of HDCT/aSCT and the potential for manifesting as fatal cardiomyopathy or long term cardiac dysfunction, also noted in a previous study of high-dose CEC11. While it is unclear whether the two deaths due to lung toxicity were directly related to cyclophosphamide or the risk imposed by previous therapy (e.g. first-line bleomycin), both drug- related deaths further support the premise that triplet cyclophosphamide-containing HDCT should not be used. We did not detect a survival difference between O-C and CE regimens which reflects the findings of a large prognostic study by Beyer and colleagues which demonstrated no significant difference in response rate, failure-free survival or overall survival between CE and CEC/ICE regimens26.
The retrospective nature of our smaller, single-institution cohort limits the power to confirm the prognostic value of disease- and treatment-related variables established in prior larger studies as well as limits the ability to draw definitive conclusions regarding HDCT and aSCT practice.The practice patterns in our study cohort may not be generalizable to other centers
for example, 57% of patients received a single transplant and we preferentially use 2 cycles of CE chemotherapy in contrast to TI-CE which uses 3 cycles of lower dose CE, a regimen developed and used at Memorial Sloan Kettering Cancer Center and part of the TI-CE and TIGER clinical trials. Therefore, the strength of our findings lie primarily in the detailed,
descriptive contrasting of outcomes over a twenty-year period.
Conclusion
In summary, by way of contrasting older versus modern HDCT and aSCT practice, we demonstrate changes in stem cell mobilization techniques and toxicity outcomes of patients with relapsed metastatic GCTs with the availability of plerixafor and use of CE. Plerixafor limits the concern of inability to mobilize if patients are treated with platinum in the bridging or second line salvage setting.
Clinical Practice Points
High-dose chemotherapy and autologous stem cell transplantation remains a standard salvage therapy, with curative potential, for relapsed germ cell tumor. Despite being an established therapy for over 20 years, practice patterns are heterogeneous owing to a lack of comparative prospective trial data. Older high-dose chemotherapy regimens may be associated with excessive toxicity. Furthermore, the role of newer adjunct agents to facilitate stem cell mobilization is less clear in germ cell tumor transplantation. This study demonstrated comparative
mobilization and toxicity outcomes by analyzing relapsed germ cell tumor patients over a 20-year period. Three-drug, oxazaphosphorine-containing chemotherapy was associated with excessive severe organ toxicities and drug-related death compared to carboplatin plus etoposide alone, and was not associated with improved survival. Successful mobilization and stem cell collection with use of the CXCR4 antagonist, plerixafor, was observed when employed prior to apheresis as well as after unsuccessful collection. These data support the incorporation of plerixafor in stem cell mobilization regimens for germ cell tumor transplantation. Plerixafor limits the concern of inability to mobilize if patients are treated with platinum in the bridging or second lien salvage setting. In the absence of improved disease outcomes, our findings like other studies, showing increased irreversible life impairing organ damage such as cardiac and liver failure support not using oxazaphosphorine-containing conditioning chemotherapy.
While using the Drop Threat Index-21 (FRI-21) customer survey, all of us examined and comparatively reviewed the fall chance between DLB along with Advertisement patients within a few defined sets of members. Final results The actual FRI-21 credit score had been drastically higher throughout DLB sufferers placental pathology when compared to AD sufferers in each and every group.
