Impact of individualized treatment on recovery from fatigue and return to work in survivors of advanced-stage Hodgkin's lymphoma: results from the randomized international GHSG HD18 trial.

BACKGROUND: Persisting cancer-related fatigue impairs health-related quality of life (HRQoL) and social reintegration in patients with Hodgkin's lymphoma (HL). The GHSG HD18 trial established treatment de-escalation for advanced-stage HL guided by positron emission tomography after two cycles (PET-2) as new standard. Here, we investigate the impact of treatment de-escalation on long-term HRQoL, time to recovery from fatigue (TTR-F), and time to return to work (TTR-W). PATIENTS AND METHODS: Patients received European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and life situation questionnaires at baseline, interim, end of treatment, and yearly follow-up. TTR-F was defined as time from the end of chemotherapy until the first fatigue score <30. TTR-W was analyzed in previously working or studying patients and measured from the end of treatment until the first documented work or education. We compared duration of treatment on TTR-F and TTR-W using Cox proportional hazards regression adjusted for confounding variables. RESULTS: HRQoL questionnaires at baseline were available in 1632 (83.9%) of all randomized patients. Overall, higher baseline fatigue and age were significantly associated with longer TTR-F and TTR-W and male sex with shorter TTR-W. Treatment reduction from eight to four chemotherapy cycles led to a significantly shorter TTR-F [hazard ratio (HR) 1.41, P = 0.008] and descriptively shorter TTR-W (HR 1.24, P = 0.084) in PET-2-negative patients. Reduction from six to four cycles led to non-significant but plausible intermediate accelerations. The addition of rituximab caused significantly slower TTR-F (HR 0.70, P = 0.0163) and TTR-W (HR 0.64, P = 0.0017) in PET-2-positive patients. HRQoL at baseline and age were the main determinants of 2-year HRQoL. CONCLUSIONS: Individualized first-line treatment in patients with advanced-stage HL considerably shortens TTR-F and TTR-W in PET-2-negative patients. Our results support the use of response-adapted shortened treatment duration for patients with HL.

Practical recommendations for fertility preservation in women by the FertiPROTEKT network. Part I: Indications for fertility preservation.

PURPOSE: Most guidelines about fertility preservation are predominantly focused on scientific evidence, but are less practically orientated. Therefore, practically oriented recommendations are needed to support the clinician in daily practice. METHODS: A selective literature search was performed based on the clinical and scientific experience of the authors, focussing on the most relevant diseases and gynaecological cancers. This article (Part I) provides information on topics that are essential for the fertility preservation indication, such as disease prognosis, disease therapy and its associated risks to fertility, recommending disease-specific fertility preservation measures. Part II specifically focusses on fertility preservation techniques. RESULTS: In breast cancer patients, fertility preservation such as ovarian tissue and oocyte cryopreservation is especially recommended in low-stage cancer and in women < 35 years of age. In Hodgkin's lymphoma, the indication is mainly based on the chemotherapy regime as some therapies have very low, others very high gonadotoxicity. In borderline ovarian tumours, preservation of fertility usually is achieved through fertility sparing surgery, ovarian stimulation may also be considered. In cervical cancer, endometrial cancer, rheumatic diseases and other malignancies such as Ewing sarcoma, colorectal carcinoma, non-Hodgkin lymphoma, leukaemia etc., several other factors must be considered to enable an individual, stage-dependent decision. CONCLUSION: The decision for or against fertility preservation depends on the prognosis, the risks to fertility and individual factors such as prospective family planning.

Sexual quality of life in Hodgkin Lymphoma: a longitudinal analysis by the German Hodgkin Study Group.

BACKGROUND: Health-related quality of life (HRQoL) comprises different domains of physical, mental, and social well-being. In this analysis, we focus on sexual quality of life in Hodgkin Lymphoma (HL) patients. METHODS: Four-thousand one-hundred and sixty patients enroled in the HD10-HD12 trials underwent HRQoL assessment. Instruments included the Quality of Life Questionnaire for survivors (QLQ-S), combining the European Organisation for Research and Treatment of Cancer QLQ-C30, Multidimensional fatigue (FA) inventory (MFI-20) and an additional sexual functioning (SX) scale. We describe SX up to 27 months after therapy and analyse relationship to stage, age, gender, FA, social functioning, and therapy. Statistical methods range from descriptive statistics to a classification of SX courses, and a longitudinal structural equations model with full information maximum likelihood estimation of missing data. In the analysis, a score below 50 was used to describe severe sexual dysfunction. RESULTS: Three-thousand two-hundred and eight patients provided data on SX. Patients in advanced stages reported lower SX than patients in early stages both, before and after the treatment. During follow-up, an improvement of SX compared with baseline was detected, except for those ≥50 years. Patients in early stages reached normal SX, whereas advanced-stage patients remained below the reference value for healthy controls. Sexual functioning during follow-up was significantly and strongly related to previous SX, other HRQoL measures, age, and stage, and to lesser degree with gender and chemotherapy. CONCLUSION: Overall, HL patients have a decreased sexual quality of life at baseline, which improves after therapy and normalises in early-stage patients. Importantly, long-term SX is more closely related to patient characteristics and SX at baseline than to the intensity of treatment.

Fertility and gonadal function in female survivors after treatment of early unfavorable Hodgkin lymphoma (HL) within the German Hodgkin Study Group HD14 trial.

BACKGROUND: In the HD14 trial, 2×BEACOPPescalated+2×ABVD (2+2) has improved the primary outcome. Compared with 4×ABVD, this benefit might be compromised by more infertility in women. Therefore, we analyzed gonadal function and fertility. PATIENTS AND METHODS: Women≤45 years in ongoing remission at least 1 year after therapy were included. Hormone parameters, menopausal symptoms, measures to preserve fertility, menstrual cycle, pregnancies, and offspring were evaluated. RESULTS: Three hundred and thirty one of 579 women addressed participated (57.2%) and 263 per-protocol treated patients qualified (A=ABVD: 137, B=2+2: 126, mean time after therapy 42 and 43 months, respectively). Regular menstrual cycle after treatment (A: 87%, B: 83%) and time to recovery (≤12 months) were not different. Follicle-stimulating hormone and anti-Muellerian hormone were significantly better in arm A. However, pregnancies after therapy favored arm B (A: 15%, B: 26%, P=0.043) and motherhood rates were equivalent to the German normal population. Multivariate analysis revealed prophylactic use of gonadotropin-releasing hormone (GnRH) analogues as highly significant prognostic factor for preservation of fertility (odds ratio=12.87, P=0.001). Severe menopausal symptoms were frequent in women≥30 years (A: 21%, B: 25%). CONCLUSIONS: Hormonal levels after 2+2 indicate a reduced ovarian reserve. However, 2+2 in combination with GnRH analogues does not compromise fertility within the evaluated observation time.

No protection of the ovarian follicle pool with the use of GnRH-analogues or oral contraceptives in young women treated with escalated BEACOPP for advanced-stage Hodgkin lymphoma. Final results of a phase II trial from the German Hodgkin Study Group.

BACKGROUND: The reduction of treatment-related toxic effects is the main goal in the current trials of the German Hodgkin Study Group (GHSG). In this regard, the protection of the ovarian reserve in young women is very important. Therefore, the GHSG investigated the use of gonadotropin-releasing hormone-analogues (GnRH-a) and oral contraceptives (OC) in young women with advanced-stage Hodgkin lymphoma (HL). PATIENTS AND METHODS: Women (18-40 years) were randomly assigned either to receive daily OC or monthly GnRH-a during escalated combination therapy with bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPPesc). Hormonal levels were determined at baseline, during therapy, and at follow-up. RESULTS: The study was closed prematurely after an interim analysis of 12 patients in arm A (OC) and 11 in arm B (GnRH-a), 9 and 10 are assessable for the primary end point. Women's median age was 25 years in both arms. The anti-Mullerian hormone level after at least 12 months was reduced in all patients. For the entire study cohort, the respective ovarian follicle preservation rate was 0% (95% confidence interval 0% to 12%). CONCLUSION: We observed no protection of the ovarian reserve with hormonal co-treatment during BEACOPPesc. This result supports efforts of ongoing trials to reduce chemotherapy intensity and toxicity. Alternative strategies for the protection of fertility must be offered to young female HL patients before the start of BEACOPPesc therapy.

Assessment of male fertility in patients with Hodgkin's lymphoma treated in the German Hodgkin Study Group (GHSG) clinical trials.

BACKGROUND: Infertility is one of the most significant side-effects in long-term survivors of successfully treated Hodgkin's lymphoma (HL). PATIENTS AND METHODS: The fertility status was assessed in male HL patients enrolled into trials of the German Hodgkin Study Group from 1988 to 2003. RESULTS: In pre-treatment analysis (n = 202), 20% of patients had normozoospermia, 11% azoospermia and 69% had other dyspermia. In post-treatment analysis (n = 112), 64% of patients had azoospermia, 30% other dyspermia and 6% normozoospermia (P < 0.001). Azoospermia was observed in 90% of patients treated with chemotherapy alone, 67% of those treated with combined modality and 11% of those treated with radiotherapy alone (P < 0.001). Azoospermia was more frequent after 4x cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastine, dacarbazine (COPP/ABVD) (91%), 8x bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone (BEACOPP) baseline (93%) and 8x BEACOPP escalated (87%) compared with 2x COPP/ABVD (56%; P = 0.003). There was a statistically significant difference in post-treatment follicle-stimulating hormone (FSH) levels between patients with azoospermia and those with preserved spermatogenesis (P = 0.001). CONCLUSIONS: Depending on the treatment received, male HL patients are at high risk of infertility after treatment. FSH might be used as surrogate parameter for male fertility in future studies.

Could BEACOPP be the new standard for the treatment of advanced Hodgkin's lymphoma (HL)?

In 1992, the German Hodgkin Study Group (GHSG) developed the BEACOPP regimen for further improving the outcome of patients with advanced Hodgkin's lymphoma (HL). Since then, BEACOPP has been introduced in 3 different prospective randomized clinical trials of the GHSG to find an equilibrium between maximal efficacy and least toxicity with the BEACOPP principle for the treatment of advanced stage HL. In the HD9 trial of the GHSG, with 1,186 patients, after a median observation time (mot) of 7 years, the rates for freedom from treatment failure (FFTF) are 85 percent, and for overall survival (OS) 90 percent for dose-escalated BEACOPP, and for COPP/ABVD (C/ABVD comparable to ABVD) the rate for FFTF is 67 percent, and for OS it is 79 percent. These superior BEACOPP results are obtained inspite of a higher rate of secondary AML/MDS in the esc. BEACOPP arm. The number of toxic deaths during treatment, however, was lower for esc. BEACOPP (1.6 percent) than for C/ABVD (1.8 percent). The majority of patients were treated in outpatient setting, in a multicenter study with more than 400 centers, including 120 private doctors, in Germany and 9 other European countries. The reduce acute and longterm toxicity, the GHSG started in the consecutive studies HD12 and HD15 for advanced stage HL to de-escalate BEACOPP by reducing the number of escalated BEACOPP cycles and by applying the baseline-dose BEACOPP, a time-dense regimen, called BEACOPP-14. The excellent results obtained with the BEACOPP principle challenge the seemingly global consensus that ABVD is the gold standard treatment strategy for advanced stage HL.

[Secondary malignancies after successful primary treatment of malignant Hodgkin's lymphoma]. / Sekundärneoplasien nach erfolgreicher Primärtherapie des malignen Hodgkin-Lymphoms.

Malignant Hodgkin's lymphoma (HL) has become a curable disease through the increasing intensity of the treatment strategies applied. These regimens are aggressive, including radiotherapy and chemotherapy leading to the possibility of secondary malignancies. The German Hodgkin Lymphoma Study Group considered three cohorts including 5,411 patients with all stages of HL. In 127 patients a secondary solid tumor was diagnosed (cumulative risk 2%, median follow-up 72 months), with bronchial carcinomas (23.6%) and colorectal adenocarcinomas (20.5%) being the most frequent neoplasms. Secondary acute myeloid leukemia was found in 36 patients, another ten developed myeloid dysplasia (cumulative risk 1%, median follow-up 55 months). A total of 52 patients revealed a non-Hodgkin's lymphoma (NHL; cumulative risk 0.9%, median follow-up 46 months). The overall incidence of secondary malignancies was 3.9% in patients who had been treated successfully for their HL with radio- and/or chemotherapy.A secondary NHL can be particularly difficult to be distinguished from the preceding HL. Therefore, in case of a suspected relapse, a complete histopathological work-up must be performed.

Twenty-five years clinical trials of the German Hodgkin Study Group (GHSG).

This review presents a short overview of 25-years of clinical trials by the GHSG for the treatment of primary Hodgkin's Lymphoma. The trials HD1-HD12 that have been conducted between 1978-2002 are reviewed and major results are discussed. Furthermore, the development of the strategies concerning chemo- and radiotherapy for the treatment of Hodgkin's Lymphoma is characterized.

VUV radiometry below 100 nm: the high-power hydrogen arc as a standard source of continuum radiation between 53 nm and 92 nm.

A stationary hydrogen arc discharge may be used as a standard source of radiation in the VUV below 100 nm. The Lyman resonance continuum is used, the cross sections of which are theoretically well known. The method described is based on optically thin radiation, requiring high plasma temperatures and an effective helium gas separation in the arc. The investigations demonstrate that, in appropriate experimental conditions, the plasma is indeed transparent down to the onset of the He ground-state absorption. Above that, the VUV spectral radiance can be predicted within less than 15% uncertainty from conventional plasma diagnostics. For a first application, the He continuum has been measured between 65 nm and 92 nm. The consistency of these results with theoretical calculations confirms the validity of the concept presented.

Differential regulation of GABA A receptor subunit mRNAs in rat cerebellar granule neurons: importance of environmental cues.

Levels of the GABA A receptor alpha1-, alpha6-, beta2-, beta3-, gamma2-, and delta-subunit mRNAs in cerebellar granule neurons rise concurrently during the second week of postnatal ontogeny. Previous studies in culture have suggested that extrinsic signals control these increases, but little is known about the nature of the regulatory cues. To determine when granule neurons become competent to express these six subunit mRNAs in mature patterns and to gain insight into their regulation, reverse transcriptase-PCR was used to examine transcript expression in cultured granule neurons prepared at 2-day intervals from postnatal days 2 through 10. Although only one pattern of expression was observed in vivo, three patterns were detected in culture. First, the levels of the alpha1- and alpha6-subunit mRNAs were constant in cultures prepared at all ages. Second, the levels of the beta2-, beta3-, and gamma2-subunit mRNAs were constant in cultures prepared at postnatal days 2-6 but increased in those prepared at days 8-10. Third, the delta-subunit mRNA level increased over time in culture regardless of cerebellar age at plating. Moreover, only delta-subunit transcript expression was modulated by cell density. These findings indicate that the subunit transcripts are differentially regulated by multiple environmental cues.

[Modern pharmacotherapy of Hodgkin disease]. / Moderne Pharmakotherapie des Morbus Hodgkin.

High cure rates have been achieved in the treatment for patients with Hodgkin's disease in the past 30 years. Depending on stage at diagnosis and further risk factors up to 95% of patients with Hodgkin's disease can be cured with first-line treatment. Modern therapeutic strategies aim at both reducing therapy-induced late toxicities while maintaining effective tumor control. Patients with early stage Hodgkin's disease are now treated with a short course of chemotherapy for control of occult disease and involved field (IF) irradiation. For patients with early unfavourable stages, effectiveness of treatment shall be optimised by introducing the escalated BEACOPP schedule which has been established in the treatment of advanced stages. Questions to be answered in the treatment of advanced stages concern the optimal number of cycles of an effective chemotherapy regimen and the necessity of additional radiation therapy. The role of erythropoetin and PET-imaging is currently being evaluated in ongoing trials. In the future, new therapeutic approaches with biological agents will be of interest.

Comparison of methods for isolation of mycobacteria from water.

Twelve methods for the isolation of mycobacteria were compared by applying them in parallel to 26 samples of surface water and 109 samples of treated water. Each method was defined by a particular combination of decontamination method, growth medium, and incubation temperature. For the decontamination of surface water, we used cetylpyridinium chloride (CPC) (30 min, 0.05%), as well as sample preincubation in tryptic soy broth (TSB) followed by decontamination with a cocktail of NaOH, cycloheximide, and malachite green. Treated water was decontaminated with 0.005 and 0.05% CPC (30 min). After enrichment by filtration, all samples were incubated on Lowenstein-Jensen medium (LJ), Ogawa egg yolk medium (OEY), and Ogawa whole-egg medium containing ofloxacin and ethambutol (OEOE) at temperatures of 30 and 37(deg)C. The efficacy of each method was determined by calculating the positivity rate, negativity rate, contamination rate, mean number of mycobacterial colonies grown, and mean number of different mycobacterial strains isolated. The last value was determined by subjecting the isolates to PCR restriction analysis and mycolic acid thin-layer chromatography. Statistical analysis demonstrated that both the TSB method and 0.05% CPC were appropriate for the decontamination of surface water. Decontamination with 0.005% CPC was best for treated water. The results for incubation on LJ were at least equal to those for incubation on OEY and always superior to the results with OEOE. At an incubation temperature of 30(deg)C, all methods achieved higher yields than at 37(deg)C.

Vacuum ultraviolet radiometry with hydrogen arcs. 2: The high power arc as an absolute standard of spectral radiance from 124 nm to 360 nm.

A wall-stabilized hydrogen arc can be utilized as a standard source of spectral radiance since the continuumemission coefficient is calculable to within a few percent. Previous efforts to apply this concept have been impeded by relatively large uncertainties associated with the plasma diagnostics. The present approach yields absolute intensities independent of other radiometric standards or the accuracy of any plasma diagnostics. The hydrogen arc is operated at high temperatures where the continuum emission coefficient reaches a broad, unique, and calculable maximum. Comparisons with other primary standards are consistent with the estimated uncertainty in the arc continuum intensities.

The prophylactic activity of amoxycillin/clavulanate and cefoxitin in vascular surgery--a randomized clinical study.

In a randomized clinical study, 141 patients who had to undergo operations on the aorta or the main arteries received either amoxycillin/clavulanate or cefoxitin perioperatively for prophylaxis. As no wound infection occurred amoxycillin/clavulanate and cefoxitin were found to be equal in effectiveness.
