Yolk Sac Tumors

BackgroundWhereas among pediatric oncologists, ovarian yolk sac tumor (O-YST) is considered a chemosensitive tumor, it is often cited as an adverse prognostic factor in adult women with ovarian germ cell tumors.MethodsThe Malignant Germ Cell International Consortium data set included 6 pediatric clinical trials (United States, United Kingdom, and France) and 2 adult gynecology clinical trials (United States). Any patient with an O-YST that was International Federation of Gynecology and Obstetrics stage IC or higher and treated with a platinum-based chemotherapy was eligible. Age was modeled as a continuous and a categorical variable (children, 0-10 years; adolescents, 11–17 years; and adults, ≥18 years). In addition, analyses to establish the optimal cut point for age were conducted. Tumors were coded as pure YST (YST +/− teratoma), mixed YST (YST + other malignant germ cell component), or putative YST (“mixed” germ cell tumor + alpha-fetoprotein >1000 ng/mL). Histology, stage (II/III vs IV), preoperative alpha-fetoprotein levels (<1000; 1000–10,000, or >10,000 ng/mL), and chemotherapeutic regimen (carboplatin vs cisplatin) were analyzed as covariates.ResultsTwo hundred fifty-one patients (median age, 13 years; range, 0–38 years) were identified (78 children, 139 adolescents, and 34 adults). Histology was pure, mixed, and putative in 129, 56, and 66 cases, respectively. Twenty-six patients had stage IV disease, similarly distributed in the 3 age groups. Median follow-up was 5.8 years. The overall 5-year event-free survival and overall survival was 91% (95% confidence interval, 87%–94%) and 96% (92%–98%), respectively. Age did not affect risk of event or death, modeled either as a categorical or continuous variable. Analysis failed to identify an age cut point that affected risk. None of the other covariates investigated had a prognostic impact on event-free survival or overall survival.ConclusionsOvarian yolk sac tumors have an excellent outcome across all age-groups. Age has no apparent impact on the probability of event or death, allowing pediatric and gynecologic oncologists to enroll patients onto joint pediatric and adult trials.

The Impact

Abstract Background: Novel therapies are required to improve the outcome of patients with AML. New agents are asked to demonstrate an overall survival (OS) benefit before qualifying for FDA approval. The long duration of clinical trials required in order to achieve this endpoint hampers quick evaluation of candidate therapies, including novel agents. Identification of reliable surrogate endpoints for OS in AML is needed. Here we compare the results of therapy for patients with untreated AML ages 16-60 years on the Eastern Cooperative Oncology Group 1900 trial (E1900) of induction chemotherapy followed by consolidation and autologous transplant in order to evaluate the validity of an event free survival (EFS) endpoint as a surrogate for OS. Methods:OS was measured from randomization for induction therapy to death from any cause (censored at last contact). EFS was measured from randomization to induction treatment failure, relapse after compete response (CR), or death in remission (censored at last contact). Hazard ratios (HR) were computed using Cox proportional hazards models. The association between EFS and OS was evaluated using the Kendall tau-a rank correlation for censored data. Results:There were657 patients enrolled of which 426 patients relapsed or had induction treatment failure before death or date of last contact. Median EFS and OS were 8.0 months (95% CI, 6.3 to 9.7 months) and 23.6 months (95% CI, 16.9 to 23.6 months), respectively. With a median follow-up of 80.1 months, there is a statistically significant correlation between EFS and OS (Kendall tau-a = 0.467, 95% confidence interval (CI) = (0.425, 0.510), p<0.001). This correlation was similarly significant at a median follow-up of 25.2 months (Kendall tau-a = 0.361, 95% CI (0.323, 0.400), p <0.001) when the E1900 trial was originally reported (Fernandez et al. NEJM 2009). Key findings reported based on the original OS endpoint are similar when analyzed with an EFS endpoint (Table 1). High-dose daunorubicin (90 mg/m2) (DNR 90) confers both an EFS and OS benefit in patients aged < 50 years and patients with intermediate cytogenetic risk, and does not confer an EFS or OS benefit in older patients and patients with unfavorable cytogenetic risk, on univariate analysis. Divergent results are only seen in the small subset of favorable cytogenetic risk patients, where DNR 90 conferred an OS benefit (p=0.027) without an EFS benefit (p=0.32). Both EFS and OS endpoints consistently reflect the impact of mutation status on survival. The presence of a FLT3-ITD or DNMT3A mutation has a negative impact on both EFS and OS while an IDH2 mutation has a favorable impact on EFS and OS. The presence of a NPM1 mutation confers a favorable impact on EFS and OS in patients who received DNR 90 and did not impact EFS or OS in patients receiving standard-dose daunorubicin (45 mg/m2) (DNR 45). The presence of an IDH1 mutation does not impact EFS or OS. Conclusions:The results of E1900 demonstrating superiority of DNR 90 in AML induction in patients up to age 60 are concordant when using an EFS or OS endpoint. This is true for the group as a whole as well as for subgroups for which targeted agents are in development (FLT3/IDH2 inhibitors). Further investigation of whether EFS is a reliable surrogate for OS is warranted in AML. If confirmed, its use as a primary endpoint could be adopted by regulatory agencies in order to allow more rapid completion of clinical trials in AML and bring new therapies to AML patients in a timely fashion.

Abstract Purpose To examine associations between parental occupation and childhood germ cell tumors (GCTs) in offspring while distinguishing by common histologic subtype (i.e., yolk sac tumor and teratoma). Methods This population-based case–control study included childhood GCT cases in Denmark diagnosed 1968–2015 (< 16 years old at diagnosis) and sex and birth year-matched controls. Demographic information and parental employment histories were obtained from Danish registries. Parental occupation was assessed by industry; job-exposure matrices were used to examine specific occupational exposures (i.e., potentially carcinogenic organic solvents and social contact). Conditional multivariable logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CIs). Results Overall, 178 childhood GCT cases (50 yolk sac tumors; 65 teratomas) and 4,355 controls were included for analysis. Maternal employment in education during pregnancy was associated with offspring GCTs (OR 2.45, 95% CI 1.23–4.90), especially yolk sac tumors (OR 5.27, 95% CI 1.94–14.28). High levels of both maternal and paternal occupational social contact were also associated with offspring yolk sac tumors across all exposure periods (ORs 2.30–4.63). No signals were observed for paternal occupational solvent exposure, while imprecise associations were estimated for maternal exposure (e.g., dichloromethane exposure during pregnancy, OR 1.51, 95% CI 0.77–2.95). Conclusion Our findings suggest that parental occupation is associated with offspring GCTs, with most consistent evidence supporting an association between maternal employment in education or other high social contact jobs and offspring yolk sac tumors.

Background:Sjögren’s Syndrome (SS) is a chronic systemic autoimmune disease of unknown etiology, carrying the highest lymphoma risk among autoimmune diseases, with significant impact on mortality and morbidity of patients.Objectives:To describe: i) the clinical phenotype of SS, ii) the histologic type, stage, treatment options regarding lymphomas and iii) the prognosis of patients with SS related lymphoproliferative disorders.Methods:Eight hundred and fifteen consecutive SS patients’ records from a single center fulfilling the 2016 ACR/EULAR were reviewed retrospectively for the purpose of this study. One hundred twenty-one patients with a diagnosis of non-Hodgkin Lymphoma (NHL) were identified and enrolled in the study population. Cumulative clinical, laboratory and histologic data were recorded and overall survival as well as event free survival curves were constructed using the Kaplan-Meier method. An event was defined as a disease progression, lymphoma relapse, treatment failure, histologic transformation, development of a 2nd lymphoma or death from any cause.Results:From 121 pSS patients with lymphoma the most common histologic type encountered was MALT lymphoma (92/121, 76,0%) followed by DLBCL (11/121, 9.0%) and NMZL (8/119, 6.6%). The remaining 10 patients had various lymphomas of B (follicular, lymphoplasmacytic, chronic lymphocytic leukemia} and T cell origin (peripheral T cell lymphoma not otherwise specified, primary cutaneous T cell lymphoma, angioimmunoblastic t-cell lymphoma). Permanent salivary gland enlargement (66.1%, 80/121), palpable purpura (34,7% 42/121), peripheral nervous involvement (9,9%, 12/121), interstitial lung disease (8,2%, 10/121) presence of serum cryoglobulins (38,7%, 43/111) and C4 hypocomplementemia (69,8% 81/116) present at least 1 year before the development of lymphoma were the main pSS related features. The median age at lymphoma diagnosis was 58 years old (range 29-82) while MALT lymphomas developed earlier compared to DLBCL from pSS diagnosis (8 vs 3 OR= 3.84, 95%CI: 0.29 to 10.46; p=0.0266). The commonest biopsy proven extranodal sites included the labial minor salivary (43,8% patients) and parotid glands (30,5%) while 11% of patients had more than 1 extranodal sites affected. Bone marrow involvement was evident in 24,3% of patients (29/119) while nodal involvement in 35,5% (42/118). The majority of patients (65%) had limited disease (stage I or II). A watch and wait therapeutic policy was chosen in 40 patients while the rest received rituximab with or without chemotherapy. The 10-year survival and event free rates were 79% and 45,5% for MALT lymphomas, 40,9% and 24,2% for DLBCL and 46% and 31% for NMZL respectively (Figure 1). The Mantel-Cox log-rank comparison of the overall survival curves revealed a statistically significant difference (p=0.0016) among lymphoma subtypes.Figure 1.Overall and event free survival of SS-associated lymphoma patients. A. Kaplan-Meier overall survival analysis. B. A Kaplan-Meier event free survival analysis.Conclusion:This is the largest single center series of SS- associated lymphoma patients, providing a detailed description of SS and lymphoma related features, combined with a 10-year survival and event free curves for the first time in the literature.Disclosure of Interests:None declared.

Purpose This retrospective cohort study aimed to determine the predictive relevance of clinical characteristics, additional cytogenetic aberrations, and cKIT and RAS mutations, as well as to evaluate whether specific treatment elements were associated with outcomes in pediatric t(8;21)-positive patients with acute myeloid leukemia (AML). Patients and Methods Karyotypes of 916 pediatric patients with t(8;21)-AML were reviewed for the presence of additional cytogenetic aberrations, and 228 samples were screened for presence of cKIT and RAS mutations. Multivariable regression models were used to assess the relevance of anthracyclines, cytarabine, and etoposide during induction and overall treatment. End points were the probability of achieving complete remission, cumulative incidence of relapse (CIR), probability of event-free survival, and probability of overall survival. Results Of 838 patients included in final analyses, 92% achieved complete remission. The 5-year overall survival, event-free survival, and CIR were 74%, 58%, and 26%, respectively. cKIT mutations and RAS mutations were not significantly associated with outcome. Patients with deletions of chromosome arm 9q [del(9q); n = 104] had a lower probability of complete remission (P = .01). Gain of chromosome 4 (+4; n = 21) was associated with inferior CIR and survival (P < .01). Anthracycline doses greater than 150 mg/m2 and etoposide doses greater than 500 mg/m2 in the first induction course and high-dose cytarabine 3 g/m2 during induction were associated with better outcomes on various end points. Cumulative doses of cytarabine greater than 30 g/m2 and etoposide greater than 1,500 mg/m2 were associated with lower CIR rates and better probability of event-free survival. Conclusion Pediatric patients with t(8;21)-AML and additional del(9q) or additional +4 might not be considered at good risk. Patients with t(8;21)-AML likely benefit from protocols that have high doses of anthracyclines, etoposide, and cytarabine during induction, as well as from protocols comprising cumulative high doses of cytarabine and etoposide.

Purpose The purpose of this study was to determine the outcome of children with nephroblastoma and pulmonary metastases (PM) treated according to International Society of Pediatric Oncology (SIOP) 93-01 recommendations using pulmonary radiotherapy (RT) in selected patients. Patients and Methods Patients (6 months to 18 years) were treated with preoperative chemotherapy consisting of 6 weeks of vincristine, dactinomycin, and epirubicin or doxorubicin. If pulmonary complete remission (CR) was not obtained, metastasectomy was considered. Patients in CR received three-drug postoperative chemotherapy, whereas patients not in CR were switched to a high-risk (HR) regimen with an assessment at week 11. If CR was not obtained, pulmonary RT was mandatory. Results Two hundred thirty-four of 1,770 patients had PM. Patients with PM were older (P < .001) and had larger tumor volumes compared with nonmetastatic patients (P < .001). Eighty-four percent of patients were in CR postoperatively, with 17% requiring metastasectomy. Thirty-five patients (16%) had multiple inoperable PM and required the HR protocol. Only 14% of patients received pulmonary RT during first-line treatment. For patients with PM, 5-year event-free survival rate was 73% (95% CI, 68% to 79%), and 5-year overall survival (OS) rate was 82% (95% CI, 77% to 88%). Five-year OS was similar for patients with local stage I and II disease (92% and 90%, respectively) but lower for patients with local stage III disease (68%; P < .001). Patients in CR after chemotherapy only and patients in CR after chemotherapy and metastasectomy had a better outcome than patients with multiple unresectable PM (5-year OS, 88%, 92%, and 48%, respectively; P < .001). Conclusion Following the SIOP protocol, pulmonary RT can be omitted for a majority of patients with PM and results in a relatively good outcome.

Introduction: Inborn errors of immunity such as hemophagocytic lymphohistiocytosis (HLH) and chronic granulomatous disease (CGD) are characterized by hyperinflammation. Hematopoietic cell transplantation (HCT) in the setting of hyperinflammation leads to high morbidity and mortality. Consequently, there is increasing use of less intense conditioning regimens, which can increase risk of mixed chimerism or graft failure. We sought to study the effect of common regimens on outcomes after HCT using data reported to the Center for International Blood and Marrow Transplant Research. Methods : 365 patients aged &lt;21 years with HLH (n=263) and CGD (n=102) were transplanted in the US between 2005-2018. Included are recipients of HLA-matched sibling (n=58; 16%) and HLA-matched (n=149; 41%) and mismatched unrelated (n=158; 43%) donor HCT. The analysis considered 3 conditioning regimen intensity groups: 1) fully myeloablative conditioning with busulfan (Bu; median dose 16 mg/kg [IQR 13-17]), cyclophosphamide (Cy) ± anti-thymocyte globulin (ATG) or alemtuzumab, n=142; 2) reduced intensity conditioning consisting of fludarabine (Flu), melphalan (Mel; 140mg/m2 [60%], 100 mg/m2 [40%]) ± alemtuzumab or ATG, n=131; and 3) reduced toxicity myeloablative conditioning consisting of either Flu, Mel (140mg/m2 [75%], 100 mg/m2 [25%]), and thiotepa (TT; 8 mg/kg or 10 mg/kg), or Flu, Bu (12mg/kg, IQR 9-15) ± alemtuzumab or ATG, n=92. The cumulative incidence rates of veno-occlusive disease (VOD) and infections were calculated. The probabilities of overall survival and event-free survival were calculated using Kaplan-Meier estimator. For event-free survival, an event was defined as the first occurrence of any of the following: primary graft failure, secondary graft failure, cellular product intervention for mixed chimerism, donor chimerism &lt;5%, second transplant, or death. The Fine and Gray method for acute and chronic GVHD and Cox regression analysis for event-free and overall survival were used to determine factors affecting outcomes. Results : Patient demographics were similar across the three treatment groups. Patients with HLH were more likely to receive the Flu/Mel regimen. Although unrelated donor HCTs were predominant across the treatment groups, cord blood graft was more common in the Bu/Cy group. Conditioning regimens changed over the study period with most Flu/Mel/TT and Flu/Bu regimens used after 2010. Consequently, outcomes were censored 2-years post-HCT to account for differences in follow-up. The day-100 incidence of VOD was higher with Bu/Cy (18%) compared to Flu/Mel (4%) and Flu/Mel/TT or Flu/Bu (7%) regimens (p&lt;0.001). The 6-month incidence of bacterial infection was higher after Bu/Cy (50%) and Flu/Mel (58%) compared to Flu/Mel/TT or Flu/Bu (43%) regimens (p=0.013). Viral infections were higher in Flu/Mel group (72%) compared to Bu/Cy (44%) and Flu/Mel/TT or Flu/Bu (56%), p&lt;0.001. There were no differences in overall survival (Figure 1A), but event-free survival (Figure 1B) was lowest with the Flu/Mel regimen, after adjusting for donor type (Table 1). Compared to matched sibling, survival was lower with matched (HR 2.41, p=0.05) and mismatched (HR 2.89, p=0.01) unrelated donor HCT. Chronic GVHD but not grade II-IV acute GVHD was lower with Flu/Mel regimen. Table 2 shows the results of multivariate analysis for HLH disorders and findings consistent with the main analysis. Conclusion : The data does not support the use of a reduced intensity Flu/Mel regimen for hyperinflammatory inborn errors of immunity. Although we did not observe differences in event-free survival between Bu/Cy and Flu/Mel/TT or Flu/Bu regimens, lower incidences of VOD and bacterial infections favor Flu/Mel/TT or Flu/Bu regimens.

Background. Cryoglobulinemia is a systemic disease and the clinical involvement is variable. The long-term renal outcome of cryoglobulinemia remains unclear, and most published series are from the western world with a high proportion of chronic hepatitis C. The objective was to determine the prevalence, causes and renal outcome of cryoglobulinemia in Hong Kong. Method. We reviewed 289 patients with cryoglobulinemia in the public hospital database of Hong Kong between 2000 and 2019. The renal event-free survival, dialysis-free survival, and overall survival were analysed according to the underlying aetiologies and compared to 7483 patients with cryoglobulin tested negative during the same period. Result. Among the cryoglobulinemic patients, 68 (23.5%) had chronic hepatitis B, 69 (23.9%) had hepatitis C, and 14 (4.8%) paraproteinemia. They were followed for 62.7 ± 58.0 months. The 5-year dialysis-free survival was 68.3%, 70.1%, 66.8%, and 82.9% for patients with cryoglobulinemia attributed to hepatitis B, hepatitis C, paraproteinemia, and unknown aetiology, respectively (p = 0.048), and their 5-year overall survival was 61.3%, 57.5%, 22.2%, and 72.4%, respectively (p = 0.002). Among hepatitis B patients, the group with cryoglobulin had a worse renal event-free survival than those without (36.4% vs 43.2%, p = 0.005), although their dialysis-free survival and all-cause mortality were similar. For patients with hepatitis C or paraproteinemia, the presence of cryoglobulin did not affect the renal outcome. Conclusion. Hepatitis B is a common cause of cryoglobulinemia in southeast Asia, and the presence of cryoglobulinemia in them is associated with a worse renal event-free survival. The renal prognosis of cryoglobulinemia appears to be affected by the underlying cause, with hepatitis B having a worse renal outcome and patients with paraproteinemia having a worse overall survival than those with other causes of cryoglobulinemia.

Purpose Paclitaxel, ifosfamide, and cisplatin (TIP) achieved complete responses (CRs) in two thirds of patients with advanced germ cell tumors (GCTs) who relapsed after first-line chemotherapy with cisplatin and etoposide with or without bleomycin. We tested the efficacy of first-line TIP in patients with intermediate- or poor-risk disease. Patients and Methods In this prospective, multicenter, single-arm phase II trial, previously untreated patients with International Germ Cell Cancer Collaborative Group poor-risk or modified intermediate-risk GCTs received four cycles of TIP (paclitaxel 240 mg/m2 over 2 days, ifosfamide 6 g/m2 over 5 days with mesna support, and cisplatin 100 mg/m2 over 5 days) once every 3 weeks with granulocyte colony-stimulating factor support. The primary end point was the CR rate. Results Of the first 41 evaluable patients, 28 (68%) achieved a CR, meeting the primary efficacy end point. After additional accrual on an extension phase, total enrollment was 60 patients, including 40 (67%) with poor risk and 20 (33%) with intermediate risk. Thirty-eight (68%) of 56 evaluable patients achieved a CR and seven (13%) achieved partial responses with negative markers (PR-negative) for a favorable response rate of 80%. Five of seven achieving PR-negative status had seminoma and therefore did not undergo postchemotherapy resection of residual masses. Estimated 3-year progression-free survival and overall survival rates were 72% (poor risk, 63%; intermediate risk, 90%) and 91% (poor risk, 87%; intermediate risk, 100%), respectively. Grade 3 to 4 toxicities consisted primarily of reversible hematologic or electrolyte abnormalities, including neutropenic fever in 18%. Conclusion TIP demonstrated efficacy as first-line therapy for intermediate- and poor-risk GCTs with an acceptable safety profile. Given higher rates of favorable response, progression-free survival, and overall survival compared with prior first-line studies, TIP warrants further study in this population.
