Maintaining success, reducing treatment burden, focusing on survivorship: highlights from the third European consensus conference on diagnosis and treatment of germ-cell cancer

In November 2011, the Third European Consensus Conference on Diagnosis and Treatment of Germ-Cell Cancer (GCC) was held in Berlin, Germany. This third conference followed similar meetings in 2003 (Essen, Germany) and 2006 (Amsterdam, The Netherlands) [Schmoll H-J, Souchon R, Krege S et al. European consensus on diagnosis and treatment of germ-cell cancer: a report of the European Germ-Cell Cancer Consensus Group (EGCCCG).

European consensus conference on diagnosis and treatment of germ-cell cancer: a report of the second meeting of the European Germ-Cell Cancer Consensus group (EGCCCG): part II. Eur Urol 2008; 53: 497–513]. A panel of 56 of 60 invited GCC experts from all across Europe discussed all aspects on diagnosis and treatment of GCC, with a particular focus on acute and late toxic effects as well as on survivorship issues. The panel consisted of oncologists, urologic surgeons, radiooncologists, pathologists and basic scientists, who are all actively involved in care of GCC patients. Panelists were chosen based on the publication activity in recent years. Before the meeting, panelists were asked to review the literature published since 2006 in 20 major areas concerning all aspects of diagnosis, treatment and follow-up of GCC patients, and to prepare an updated version of the previous recommendations to be discussed at the conference. In addition, ∼50 E-vote questions were drafted and presented at the conference to address the most controversial areas for a poll of expert opinions. Here, we present the main recommendations and controversies of this meeting. The votes of the panelists are added as online supplements.

Late relapse of germ cell tumors after cisplatin-based chemotherapy

BACKGROUND Sparse data are available with regard to the incidence, clinical characteristics, therapeutic management and prognosis of male patients with germ cell tumors, who relapse more than two years after completion of cisplatin-based chemotherapy. PATIENTS AND METHODS A review of 530 patients treated at two institutions from 1978 to April 1994 was conducted. Twenty-five cases of late relapse were identified. Cumulative risk of late relapse was calculated according to the Kaplan-Meier method. RESULTS 418 of 523 patients (80%) who received their first-line treatment at our institutions were relapse-free at two years. Among these 418 patients 18 cases (4.3%) developed a late relapse. The cumulative risk of late relapse was 1.1% at five years and 4.0% at ten years excluding patients with prior early relapses who carried risks of 9.4% and 29%, respectively (P < 0.0001). No case of late relapse was observed among patients receiving adjuvant chemotherapy. The risk of late relapse was lower in patients with good-risk non-seminomatous germ cell tumors than in poor-risk patients according to Medical Research Council criteria (P < 0.01). Seven further patients were referred from other institutions for treatment of late relapse. At a median follow-up of 38 months (range, 3 to 121) after treatment of late relapse 9 of 25 patients (36%) are continuously disease-free. Six of these nine patients had surgical resection of carcinoma or teratoma as a component of their therapy. CONCLUSION The incidence of late relapse after cisplatin-based chemotherapy of germ cell tumors is related to initial tumor burden and is somewhat higher than previously expected. Chemotherapy seems to have only minor curative potential, but localized resectable disease can be cured by surgery. Annual follow-up evaluations allow to detect the majority of late relapses at an asymptomatic stage and should be extended throughout the patients life.

Impact of human herpesvirus-6 after haematopoietic stem cell transplantation

We studied 228 consecutive stem cell transplant recipients, screened for reactivation of human herpesvirus‐6 (HHV‐6) in peripheral blood and other specimens as clinically indicated by means of qualitative polymerase chain reaction. Among them, 197 received an allograft and 31 autograft. Ninety‐six of 228 patients (42·1%) showed HHV‐6 reactivation in peripheral blood and 129 of 228 (56·6%) demonstrated HHV‐6 in at least one of the specimens tested. 41·9% of patients were asymptomatic when HHV‐6 was identified. Clinical features, noted when HHV‐6 was detected, included interstitial or alveolar pneumonia, gastroduodenal and colorectal disease, bone marrow suppression and liver disease. However, based on clinical and histopathological criteria, HHV‐6 was considered a causal agent in only a minority of patients, in particular, those suffering from bone marrow suppression (n = 11), gastroduodenitis (five), colitis (three), interstitial/alveolar pneumonia (five), skin rash (one), pericarditis (two) and encephalitis (one). HHV‐6 reactivation was significantly associated with the occurrence of graft‐versus‐host disease [odds ratio (OR) 5·31], Epstein–Barr virus coinfection (OR 8·89) and unrelated donor transplantation (OR 5·67) indicating an increased stage of immunosuppression.

Dose-dense induction with sequential high-dose cytarabine and mitoxantone (S-HAM) and pegfilgrastim results in a high efficacy and a short duration of critical neutropenia in de novo acute myeloid leukemia: a pilot study of the AMLCG

Dose density during early induction has been demonstrated to be one of the prime determinants for treatment efficacy in acute myeloid leukemia (AML). The German AML Cooperative Group has therefore piloted a dose-dense induction regimen sequential high-dose AraC and mitoxantrone followed by pegfilgrastim (S-HAM) in which 2 induction cycles are applied over 11 to 12 days instead of 25 to 29 days as used in conventional double induction, thereby increasing dose density 2-fold. Of 172 de novo AML patients (excluding acute promyelocytic leukemia), 61% reached a complete remission, 22% a complete remission with incomplete peripheral recovery, 7% had persistent leukemia, 10% died (early death) resulting in an overall response rate of 83%. Kaplan-Meier estimated survival at 2 years was 61% for the whole group (patients with unfavorable karyotypes, 38%; patients with favorable karyotypes, 69%; patients with intermediate karyotypes, 75%) after S-HAM treatment. Importantly, the compression of the 2 induction cycles into the first 11 to 12 days of treatment was beneficial for normal hematopoiesis as demonstrated by a significantly shortened duration of critical neutropenia of 31 days compared with 46 days after conventionally timed double induction.

IgMA-enriched immunoglobulin in neutropenic patients with sepsis syndrome and septic shock: a randomized, controlled, multiple-center trial.

Objective:To evaluate the effect of intravenous IgMA-enriched immunoglobulin (ivIGMA) therapy on mortality in neutropenic patients with hematologic malignancies and sepsis syndrome or septic shock. Design:Multiple-center, prospective randomized, controlled study. Setting:Six university hospitals in Germany. Patients:Patients were 211 neutropenic patients with sepsis syndrome or septic shock after chemotherapy for severe hematologic disorders between 1992 and 1999. Interventions:Patients received 1300 mL of ivIGMA (7.8 g IgM, 7.8 g IgA, and 49.4 g IgG) infused intravenously within a period of 72 hrs or human albumin according to the same schedule as ivIGMA. Measurements and Main Results:All-cause mortality at 28 days, sepsis-related mortality at 28 days, all-cause mortality at 60 days, mortality from septic shock, and mortality from microbiologically proven Gram-negative sepsis and septic shock were recorded. Immunoglobulin had no benefit over human albumin. The 28-day mortality rate was 26.2% and 28.2% in the ivIGMA and control patients, respectively (difference, 2.0% [95% confidence interval, −10.2 to 14.2 percentage points]). Likewise, the 60-day mortality rate did not differ between both arms (29.6% vs. 34.7% in the ivIGMA and control patients, respectively). Mortality rates in patients with sepsis syndrome (17.1% vs. 16.7%) and septic shock (51.9% vs. 54.8%) were also found to be similar between both groups. Conclusions:Intravenous ivIGMA had no beneficial effects in neutropenic patients with hematologic malignancies and sepsis syndrome and septic shock.

Stage-Adapted Treatment of HIV-Associated Hodgkin Lymphoma: Results of a Prospective Multicenter Study

PURPOSE Although the outcome of patients with HIV-related Hodgkin lymphoma (HIV-HL) has markedly improved since the introduction of combined antiretroviral therapy, standard therapy is still poorly defined. This prospective study investigates a stage- and risk-adapted treatment strategy in patients with HIV-HL. PATIENTS AND METHODS Patients with early favorable HIV-HL received two to four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by 30 Gy of involved-field (IF) radiation. In patients with early unfavorable HIV-HL, four cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP baseline) or four cycles of ABVD + 30 Gy of IF radiation were administered. Six to eight cycles of BEACOPP baseline were given in patients with advanced-stage HIV-HL. In patients with advanced HIV infection, BEACOPP was replaced with ABVD. RESULTS Of 108 patients (including eight female patients) included in the study, 23 (21%) had early favorable HL, 14 (13%) had early unfavorable HL, and 71 (66%) had advanced-stage HL. The median CD4 count at HL diagnosis was 240/μL. The complete remission rates for patients with early favorable, early unfavorable, and advanced-stage HL were 96%, 100%, and 86%, respectively. The 2-year progression-free survival of the entire study population was 91.7%. Eleven patients (11%) have died, and treatment-related mortality was 5.6%. The 2-year overall survival rate was 90.7% with no significant difference between early favorable (95.7%), early unfavorable (100%), and advanced-stage HL (86.8%). CONCLUSION In patients with HIV-HL, stage- and risk-adapted treatment is feasible and effective. The prognosis for patients with HIV-HL may approach that of HIV-negative patients with HL.

Management of sepsis in neutropenic patients: guidelines from the infectious diseases working party of the German Society of Hematology and Oncology

Sepsis is a leading cause of mortality in neutropenic cancer patients. Early initiation of effective causative therapy as well as intensive adjunctive therapy is mandatory to improve outcome. We give recommendations for the management of adults with neutropenia and sepsis. The guidelines are written for clinicians involved in care of cancer patients and focus on pathophysiology, diagnosis and treatment of sepsis during neutropenia.

High antileukemic efficacy of an intermediate intensity conditioning regimen for allogeneic stem cell transplantation in patients with high-risk acute myeloid leukemia in first complete remission

The goal of this analysis was to define the role of the moderate-intensity fludarabin Ara-C amsacrin (FLAMSA)-reduced intensity conditioning (RIC) regimen for patients with high-risk AML undergoing allogeneic SCT (alloSCT) in first CR1. High-risk was defined by (1) AML secondary to MDS or radio/chemotherapy, (2) unfavorable cytogenetics or (3) delayed response to induction chemotherapy. A total of 23 of 44 AML patients referred to the University of Munich for alloSCT in CR1 between 1999 and 2006 fulfilled these criteria and received FLAMSA chemotherapy, followed by RIC (4 Gy TBI/cyclophosphamide/ATG) for alloSCT. Twenty-two patients engrafted, one died in aplasia. Two-year cumulative incidences for relapse and nonrelapse mortality (NRM) were 4.6 and 22.5%, respectively. Four-year overall and leukemia-free survival was 72.7% (median follow-up among survivors: 35 months). The results of this high-risk cohort were compared to the outcome of 21 consecutive standard-risk patients <55 years, who had received standard, myeloablative sibling SCT in CR1 AML within the same center and time period. Survival and cumulative incidences of relapse and NRM were identical in both groups. In conclusion, the FLAMSA-RIC regimen produces long-term remission in a high proportion of patients with high-risk AML transplanted in CR1. In this cohort, FLAMSA-RIC showed equivalent antileukemic activity as compared to the standard protocols.

Management of sepsis in neutropenic patients: 2014 updated guidelines from the Infectious Diseases Working Party of the German Society of Hematology and Medical Oncology (AGIHO)

Sepsis is a major cause of mortality during the neutropenic phase after intensive cytotoxic therapies for malignancies. Improved management of sepsis during neutropenia may reduce the mortality of cancer therapies. Clinical guidelines on sepsis treatment have been published by others. However, optimal management may differ between neutropenic and non-neutropenic patients. Our aim is to give evidence-based recommendations for haematologist, oncologists and intensive care physicians on how to manage adult patients with neutropenia and sepsis.

Management and outcome of bilateral testicular germ cell tumors: Twenty-five year experience in Munich

We analyzed characteristics, therapy and outcome of patients with bilateral testicular germ cell tumor (TGCT) at our institutions. Among 1 180 TGCT patients diagnosed and/or treated between 1979 and 2003, 47 (4.0%) developed a second TGCT. Nine of 14 patients (64%) with synchronous TGCT are alive with no evidence of disease (NED) at a median follow-up of 37 months. Thirty-three patients had a metachronous bilateral TGCT. Median time to the 2nd TGCT was 71 months. At diagnosis of 2nd TGCT 30 patients had stage I, 1 had stage II and 2 had stage III disease. Thirty-two of 33 patients are alive with NED at a median follow up of 41 months. No patient died from second TGCT. As a review of the literature confirms our data we do not recommend a routine biopsy of the contralateral testicle for early detection of testicular intraepithelial neoplasia (TIN).
