RESUMEN

Long-term data of chronic lymphocytic leukemia (CLL) patients with favorable risk who were treated with fludarabine, cyclophosphamide, and rituximab (FCR) within clinical trials show good efficacy. We here report long-term data collected within the GCLLSG registry. Altogether, 417 CLL patients who received first-line treatment with FCR were analyzed, of which 293 (70.3%) were treated outside of clinical trials. The median observation time from first-line was 95.8 (interquartile range 58.7-126.8) months. Focusing on data of 194 (46.5%) patients who received FCR first-line treatment after 2013 (start of data collection within GCLLSG registry), responses were documented in 85% of the patients, non-responses in 15%, and for 3.6% the assessment was missing. Median event-free survival (EFS, time until disease progression, subsequent treatment, or death) was 60.2 months with a 5-year EFS-rate of 50.6%. Patients with higher-risk disease, characterized by unmutated IGHV (N = 78), had a median EFS of 45.4 months with a 5-year EFS rate of 36.3%, while the median EFS was 77.5 months with a 5-year EFS rate of 60.3% in patients with mutated IGHV (N = 40). Median overall survival was not reached with a 5-year survival rate of 92.7%. In summary, first-line FCR was associated with long EFS, especially in patients exhibiting a mutated IGHV status.

RESUMEN

Ruxolitinib (RUX) is a Janus kinase 1/2 inhibitor (JAKi) approved in the EU for treating disease­related splenomegaly or symptoms in adults patients with myelofibrosis (MF). This is an interim analysis of JAKoMo, a prospective, non­interventional, phase IV study in MF. Between 2012-2019 (cutoff March 2021), 928 patients (JAKi-naïve and -pretreated) enrolled from 122 German centers. This analysis focuses on JAKi-naïve patients. RUX was administered according to the Summary of Product Characteristics. Compared to the COMFORT-I, -II, and JUMP trials, patients in JAKoMo were older (median 73 years), had poorer Eastern Cooperative Oncology Group (ECOG) performance statuses (16.5% had ECOG ≥ 2), and were more transfusion dependent (48.5%). JAKoMo represents the more challenging patients with MF encountered outside of interventional studies. However, patients with low-risk International Prognostic Scoring System (IPSS) scores or without palpable splenomegaly were also included. Following RUX treatment, 82.5% of patients experienced rapid (≤ 1 month), significant decreases in palpable spleen size, which remained durable for 24 months (60% patients). Symptom assessment scores improved significantly in Month 1 (median -5.2) up to Month 12 (-6.2). Common adverse events (AEs) were anemia (31.2%) and thrombocytopenia (28.6%). At cutoff, 54.3% of patients had terminated the study due to, death, AEs, or deterioration of health. No new safety signals were observed. Interim analysis of the JAKoMo study confirms RUX safety and efficacy in a representative cohort of real-world, elderly, JAKi-naïve patients with MF. Risk scores were used in less than half of the patients to initiate RUX treatment.Trial registration: NCT05044026; September 14, 2021.

RESUMEN

Few data exist on health-related quality of life (QoL) in patients with metastatic pancreatic cancer (mPC) receiving first-line chemotherapy (Awad L ZE, Mesbah M Boston, MA. Applying survival data methodology to analyze quality of life data, in Mesbah M, Cole BF, Ting Lee M-L (eds): Statistical Methods for Quality of Life Studies: Design, Measurements and Analysis. Kluwer Academic Publishers 2002). The QOLIXANE study is a prospective, noninterventional, multicenter substudy of the Platform for Outcome, Quality of Life and Translational Research on Pancreatic Cancer (PARAGON) registry, which evaluated QoL in patients with mPC receiving first-line gemcitabine and nab-paclitaxel chemotherapy in real-life setting. QoL was prospectively measured via EORTC QLQ-C30 questionnaires at baseline and every month thereafter. Therapy and efficacy parameters were prospectively collected. Main objectives were the rate of patients without deterioration of Global Health Status/QoL (GHS/QoL) at 3 and 6 months. Six hundred patients were enrolled in 95 German study sites. Median progression-free survival was 5.9 months (95% confidence interval [CI], 5.2-6.3). Median overall survival (OS) was 8.9 months (95% CI, 7.9-10.2), while median time to deterioration of GHS/QoL was 4.7 months (95% CI, 4.0-5.6). With a baseline GHS/QoL score of 46 (SD, 22.8), baseline QoL of the patients was severely impaired, in most cases due to loss in role functioning and fatigue. In the Kaplan-Meier analysis, 61% and 41% of patients had maintained GHS/QoL after 3 and 6 months, respectively. However, in the QoL response analysis, 35% and 19% of patients had maintained (improved or stable) GHS/QoL after 3 and 6 months, respectively, while 14% and 9% had deteriorated GHS/QoL with the remaining patients being nonevaluable. In the Cox regression analysis, GHS/QoL scores strongly predicted survival with a hazard ratio of 0.86 (P < .0001). Patients with mPC have poor QoL at baseline that deteriorates within a median of 4.7 months. Treatment with gemcitabine and nab-paclitaxel is associated with maintained QoL in relevant proportions of patients. However, overall, results remain poor, reflecting the aggressive nature of the disease.

RESUMEN

Owing to its heterogeneity and rarity, management of disseminated marginal zone B-cell lymphoma (MZL) remains largely understudied. We present prospective data on choice of systemic treatment and survival of patients with MZL treated in German routine practice. Of 175 patients with MZL who had been documented in the prospective clinical cohort study Tumour Registry Lymphatic Neoplasms (NCT00889798) collecting data on systemic treatment, 58 were classified as extranodal MZL of mucosa-associated lymphoid tissue (MALT) and 117 as non-MALT MZL. We analyzed the most commonly used first-line and second-line chemo(immuno)therapies between 2009 and 2016 and examined objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and prognostic factors for survival. Compared to patients with MALT MZL, those with non-MALT MZL more often presented with bone marrow involvement (43% vs. 14%), Ann Arbor stage III/IV (72% vs. 57%) and were slightly less often in good general condition (ECOG = 0; 41% vs. 47%). In German routine practice, rituximab-bendamustine for a median of 6 cycles was the most frequently used first-line (76%) and second-line treatment (36%), with no major differences between MZL subtypes. The ORR for patients encompassing any positive response was 81%. For patients with MALT and non-MALT MZL, respectively, 5-years PFS was 69% (95% CI 52%-81%) and 66% (95% CI 56%-75%), 5-years OS 79% (95% CI 65%-89%) and 75% (95% CI 66%-83%). Cox proportional hazards models showed a significantly increased risk of mortality for higher age in all patient groups. Our prospective real world data give valuable insights into the management and outcome of non-selected patients with MZL requiring systemic treatment and can help optimize therapy recommendations.

RESUMEN

BACKGROUND: The effects of intravenous immunoglobulin G replacement on perceived health and infection susceptibility of patients suffering from immunoglobulin G (IgG) deficiencies should be evaluated in a prospective analysis. METHODS: Patients with symptomatic primary or secondary IgG deficiencies were interviewed prior to the first IgG infusion (t0) and over the course of their treatment (t1 - t6). The respondents rated their current health using a 100 point scale (EQ-5D-5L), ranging from 0 ('worst imaginable health') to 100 ('best imaginable health'). The patients also provided information on the frequency of infections and of infections requiring antibiotics in the past 8 weeks. A healthy control group (CG) without oncologic diseases answered the questions once. RESULTS: One hundred six patients with a median age of 65 years (21-85 years) were investigated. The median serum IgG concentration changed from 500 mg/dl (t0) to 772 mg/dl (t6). The mean number of infections and of infections requiring antibiotics decreased during IgG replacement significantly. Current health according to EQ-5D-5L improved from 57 (t0) to 68 (t6), compared to 73 in the CG. CONCLUSION: During the course of IgG replacement patients reported fewer and less severe infections. Their health assessment improved but still was inferior to the healthy CG.

RESUMEN

BACKGROUND: Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma. This study reports on the safety and efficacy of the docetaxel-based triplet FLOT (fluorouracil plus leucovorin, oxaliplatin and docetaxel) as a perioperative therapy for patients with locally advanced, resectable tumours. METHODS: In this controlled, open-label, phase 2/3 trial, we randomly assigned 716 patients with histologically-confirmed advanced clinical stage cT2 or higher or nodal positive stage (cN+), or both, resectable tumours, with no evidence of distant metastases, via central interactive web-based-response system, to receive either three pre-operative and three postoperative 3-week cycles of 50 mg/m2 epirubicin and 60 mg/m2 cisplatin on day 1 plus either 200 mg/m2 fluorouracil as continuous intravenous infusion or 1250 mg/m2 capecitabine orally on days 1 to 21 (ECF/ECX; control group) or four preoperative and four postoperative 2-week cycles of 50 mg/m2 docetaxel, 85 mg/m2 oxaliplatin, 200 mg/m2 leucovorin and 2600 mg/m2 fluorouracil as 24-h infusion on day 1 (FLOT; experimental group). The primary outcome of the trial was overall survival (superiority) analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01216644. FINDINGS: Between Aug 8, 2010, and Feb 10, 2015, 716 patients were randomly assigned to treatment in 38 German hospitals or with practice-based oncologists. 360 patients were assigned to ECF/ECX and 356 patients to FLOT. Overall survival was increased in the FLOT group compared with the ECF/ECX group (hazard ratio [HR] 0·77; 95% confidence interval [CI; 0.63 to 0·94]; median overall survival, 50 months [38·33 to not reached] vs 35 months [27·35 to 46·26]). The number of patients with related serious adverse events (including those occurring during hospital stay for surgery) was similar in the two groups (96 [27%] in the ECF/ECX group vs 97 [27%] in the FLOT group), as was the number of toxic deaths (two [<1%] in both groups). Hospitalisation for toxicity occurred in 94 patients (26%) in the ECF/ECX group and 89 patients (25%) in the FLOT group. INTERPRETATION: In locally advanced, resectable gastric or gastro-oesophageal junction adenocarcinoma, perioperative FLOT improved overall survival compared with perioperative ECF/ECX.

RESUMEN

OBJECTIVES: This study was conducted to investigate the real-world effectiveness and tolerability of rituximab-containing chemoimmunotherapies, which have become the standard of care for chronic lymphocytic leukaemia (CLL), particularly for physically fit patients. Furthermore, current treatment patterns in clinical practice were documented, and an unselected real-life population was compared with older, comorbid patients. METHODS: Prospective, multicentre, observational study with rituximab-containing chemoimmunotherapy in CLL patients. RESULTS: Of 681 patients in total, 485 were enroled in cohort 1 (unselected) and 196 in cohort 2 (comorbid "slow-go" patients). The median patient age was higher than in most randomised controlled trials (cohort 1: 70 years and cohort 2: 75 years). The most common treatment regimen in both first-line and relapsed patients was rituximab-bendamustine. Two-year progression-free survival rate for first-line therapy was 84.1% for cohort 1 and 69.8% for cohort 2 (with best overall response rate 81.8% for cohort 1 and 76.6% for cohort 2). General and B-symptoms declined during treatment and remained at low level or decreased further until study end. The safety profile observed in randomised clinical trials was confirmed. CONCLUSION: Chemoimmunotherapy with rituximab is feasible and safe in a wide variety of clinical settings in CLL, including the treatment of older patients with comorbidities (ClinicalTrials.gov NCT01178086).

RESUMEN

Molecular genetics may influence outcome for patients with myelofibrosis. To determine the impact of molecular genetics on outcome after allogeneic stem cell transplantation, we screened 169 patients with primary myelofibrosis (n = 110), post-essential thrombocythemia/polycythemia vera myelofibrosis (n = 46), and myelofibrosis in transformation (n = 13) for mutations in 16 frequently mutated genes. The most frequent mutation was JAK2V617F (n = 101), followed by ASXL1 (n = 49), calreticulin (n = 34), SRSF2 (n = 16), TET2 (n = 10), U2AF1 (n = 11), EZH2 (n = 7), MPL (n = 6), IDH2 (n = 5), IDH1 (n = 4), and CBL (n = 1). The cumulative incidence of nonrelapse mortality (NRM) at 1 year was 21% and of relapse at 5 years 25%. The 5-year rates progression-free (PFS) and overall survival (OS) were and 56%, respectively. In a multivariate analysis CALR mutation was an independent factor for lower NRM (HR, .415; P = .05), improved PFS (HR, .393; P = .01), and OS (HR, .448; P = .03). ASXL1 and IDH2 mutations were independent risk factors for lower PFS (HR, 1.53 [P = .008], and HR, 5.451 [P = .002], respectively), whereas no impact was observed for "triple negative" patients. Molecular genetics, especially CALR, IDH2, and ASXL1 mutations, may thus be useful to predict outcome independently from known clinical risk factors after allogeneic stem cell transplantation for myelofibrosis.

RESUMEN

BACKGROUND: Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma, but has not yet been evaluated in the context of resectable patients. Here we report findings from the phase 2 part of the phase 2/3 FLOT4 trial, which compared histopathological regression in patients treated with a docetaxel-based triplet chemotherapy versus an anthracycline-based triplet chemotherapy before surgical resection. METHODS: In this randomised, open-label, phase 2/3 study, eligible participants were recruited from 28 German oncology centres. Patients with resectable gastric or gastro-oesophageal junction cancer who had clinical stage cT2 or higher, nodal positive (cN+) disease, or both were randomly assigned (1:1) to either three preoperative and three postoperative 3-week cycles of intravenous epirubicin 50 mg/m2 on day 1, intravenous cisplatin 60 mg/m2 on day 1, and either fluorouracil 200 mg/m2 as continuous intravenous infusion or capecitabine 1250 mg/m2 orally (two doses of 625 mg/m2 per day) on days 1 to 21 (ECF/ECX group) or four preoperative and four postoperative 2-week cycles of docetaxel 50 mg/m2, intravenous oxaliplatin 85 mg/m2, intravenous leucovorin 200 mg/m2, and fluorouracil 2600 mg/m2 as a 24 h infusion, all on day 1 (FLOT group). Randomisation was done centrally with an interactive web-response system based on a sequence generated with blocks (block size 2) stratified by Eastern Cooperative Oncology Group performance status, location of primary tumour, age, and nodal status. No masking was done. Central assessment of pathological regression was done according to the Becker criteria. The primary endpoint was pathological complete regression (tumour regression grade TRG1a) and was analysed in the modified intention-to-treat population, defined as all patients who were randomly assigned to treatment excluding patients who had surgery but did not provide resection specimens for central evaluation. The study (including the phase 3 part) has completed enrolment, but follow-up is ongoing and this is an interim analysis. The trial is registered with ClinicalTrials.gov, number NCT01216644. FINDINGS: Between Aug 18, 2010, and Aug 10, 2012, 300 patients (152 patients in the ECF/ECX group; 148 patients in the FLOT group) were enrolled into the phase 2 part of the study, 265 of whom (137 in the ECF/ECX group; 128 in the FLOT group) were assessable on a modified intention-to-treat basis. 119 (93%) of 128 patients in the FLOT group and 126 (92%) of 137 patients in the ECF/ECX group were given all planned preoperative cycles of treatment. FLOT was associated with significantly higher proportions of patients achieving pathological complete regression than was ECF/ECX (20 [16%; 95% CI 10-23] of 128 patients vs eight [6%; 3-11] of 137 patients; p=0·02). 44 (40%) of 111 patients in the ECF/ECX group and 30 (25%) of 119 patients in the FLOT group had at least one serious adverse event involving a perioperative medical or surgical complication. The most common non-surgical grade 3-4 adverse events were neutropenia (52 [38%] of 137 patients in the ECF/ECX group vs 67 [52%] of 128 patients in the FLOT group), leucopenia (28 [20%] vs 36 [28%]), nausea (23 [17%] vs 12 [9%]), infection (16 [12%] vs 15 [12%]), fatigue (19 [14%] vs 11 [9%]), and vomiting (13 [10%] vs four [3%]). INTERPRETATION: Perioperative FLOT was active and feasible to administer, and might represent an option for patients with locally advanced, resectable gastric or gastro-eosophageal junction adenocarcinoma. FUNDING: None.

RESUMEN

We experimentally demonstrate the generation and transmission of a single-lane 180 Gbit/s (90 GBaud) four-level pulse-amplitude modulation (PAM-4) signal in an intensity-modulation direct-detection system with a 7.5 GHz 3 dB bandwidth. The generated signal is transmitted over a 2 km standard single-mode fiber with, to the best of our knowledge, the highest reported net data rate in the C-band: 150 Gbit/s. A net data rate of 168 Gbit/s is also reachable with 1 km reach. The PAM-4 and duobinary (DB) PAM-4 modulation schemes are compared; the obtained results show that DB-PAM-4 significantly outperforms PAM-4 in the considered strong bandwidth-constrained system. Both a feed-forward equalizer and a maximum-likelihood sequence estimator are investigated for data recovery.

RESUMEN

Myelodysplastic syndromes and myeloproliferative neoplasms both represent hematologic diseases associated with bone marrow failure often resulting in anemia. For those patients, transfusion of red blood cell (RBC) units is essential but results in iron overload (IOL) that may affect various organ functions. Therefore, iron chelation therapy plays a major role in anemic patients, not only because it reduces IOL, but also because it may improve hematopoietic function by increasing hemoglobin or diminishing the requirement for RBC transfusions. To assess the utility, efficacy, and safety of the different iron chelation medications approved in Germany, as well as to examine the effect of chelation on hematopoietic insufficiency, a prospective, multicenter, noninterventional study named EXCALIBUR was designed. In total, 502 patients from 106 German hospitals and medical practices were enrolled. A large proportion of patients switched from a deferasirox dispersible tablet to a deferasirox-film-coated tablet, mainly because of more convenient application, which was reflected in the treatment satisfaction questionnaire for medication scores. Iron chelation was effective in lowering serum ferritin levels, with the observed adverse drug reactions being in line with the known safety profile. Hematologic response occurred in a few patients, comparable to other studies that examined hematologic improvement in patients with MDS.

RESUMEN

BACKGROUND: Symptomatic anemia is a frequent and severe complication of chemotherapy that is commonly treated with erythropoiesis-stimulating agents. The primary objective of this study was to assess the change in hemoglobin levels in patients with chemotherapy-induced anemia (CIA) following treatment with biosimilar Retacrit® (epoetin zeta). Secondary objectives included changes in hematologic parameters and tolerability. METHODS: This was a non-interventional, multicenter, long-term observational study that is part of an ongoing surveillance program for epoetin zeta. Adult patients (N=291) with solid tumors, malignant lymphomas or multiple myeloma, and chemotherapy-induced symptomatic anemia, who were eligible for treatment with biosimilar epoetin zeta, were enrolled. Patients were evaluated at enrollment, 3 months, and 6 months. RESULTS: Evaluable patients had lymphoma or myeloma (n=30) or solid tumors (n=260). At 3 months, patients with lymphoma and myeloma showed the greatest increase in mean (SD) hemoglobin from 9.2 (0.9) to 11.0 (1.8) g/dL, whereas patients with breast cancer showed the smallest increase from 10.0 (1.0) to 11.1 (1.2) g/dL. At 6 months, the greatest mean increase occurred in patients with lymphoma or myeloma from 11.0 (1.8) to 11.7 (2.3) g/dL, and the smallest in patients with other solid tumors from 10.9 (1.4) to 11.1 (1.5) g/dL. Patient evaluation of epoetin zeta therapy was positive, as most patients expressed satisfaction with epoetin zeta treatment during the study, compliance with treatment was high, and most indicated their willingness to be retreated if necessary. Epoetin zeta was also well tolerated; overall, in 25 patients (8.6%), there were 31 adverse events. CONCLUSION: Despite variability among different disease groups, epoetin zeta was effective and well tolerated in patients with different types of solid tumors and hematologic malignancies.

RESUMEN

IMPORTANCE: Surgical resection has a potential benefit for patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction. OBJECTIVE: To evaluate outcome in patients with limited metastatic disease who receive chemotherapy first and proceed to surgical resection. DESIGN, SETTING, AND PARTICIPANTS: The AIO-FLOT3 (Arbeitsgemeinschaft Internistische Onkologie-fluorouracil, leucovorin, oxaliplatin, and docetaxel) trial is a prospective, phase 2 trial of 252 patients with resectable or metastatic gastric or gastroesophageal junction adenocarcinoma. Patients were enrolled from 52 cancer care centers in Germany between February 1, 2009, and January 31, 2010, and stratified to 1 of 3 groups: resectable (arm A), limited metastatic (arm B), or extensive metastatic (arm C). Data cutoff was January 2012, and the analysis was performed in March 2013. INTERVENTIONS: Patients in arm A received 4 preoperative cycles of fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) followed by surgery and 4 postoperative cycles. Patients in arm B received at least 4 cycles of neoadjuvant FLOT and proceeded to surgical resection if restaging (using computed tomography and magnetic resonance imaging) showed a chance of margin-free (R0) resection of the primary tumor and at least a macroscopic complete resection of the metastatic lesions. Patients in arm C were offered FLOT chemotherapy and surgery only if required for palliation. Patients received a median (range) of 8 (1-15) cycles of FLOT. MAIN OUTCOMES AND MEASURES: The primary end point was overall survival. RESULTS: In total, 238 of 252 patients (94.4%) were eligible to participate. The median (range) age of participants was 66 (36-79) years in arm A (n = 51), 63 (28-79) years in arm B (n = 60), and 65 (23-83) years in arm C (n = 127). Patients in arm B (n = 60) had only retroperitoneal lymph node involvement (27 patients [45%]), liver involvement (11 [18.3%]), lung involvement (10 [16.7%]), localized peritoneal involvement (4 [6.7%]), or other (8 [13.3%]) incurable sites. Median overall survival was 22.9 months (95% CI, 16.5 to upper level not achieved) for arm B, compared with 10.7 months (95% CI, 9.1-12.8) for arm C (hazard ratio, 0.37; 95% CI, 0.25-0.55) (P < .001). The response rate for arm B was 60% (complete, 10%; partial, 50%), which is higher than the 43.3% for arm C. In arm B, 36 of 60 patients (60%) proceeded to surgery. The median overall survival was 31.3 months (95% CI, 18.9-upper level not achieved) for patients who proceeded to surgery and 15.9 months (95% CI, 7.1-22.9) for the other patients. CONCLUSIONS AND RELEVANCE: Patients with limited metastatic disease who received neoadjuvant chemotherapy and proceeded to surgery showed a favorable survival. The AIO-FLOT3 trial provides a rationale for further randomized clinical trials. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT00849615.

RESUMEN

In patients with acute leukemia we investigated the illness perceptions, lay theories and coping strategies 1 week after diagnosis. Semi-structured in-depth interviews were conducted with 12 patients. The transcribed interviews were analyzed by methods of qualitative research. Dramatic narrations of overwhelming threat in younger patients contrast to rationalization in elderly patients. Feelings of helplessness and efforts of normalization become apparent. Intense descriptions of physical injury due to invasive procedures allow verbalizing the fear of the disease. While coping strategies are complex, the overall importance of trust is recognized. Mortal fears are indirectly indicated. The results have consequences for psycho-oncological training and patient education.

RESUMEN

The risk of venous thromboembolism is increased in patients with lymphoma and leukemia; however, little is known about the potential underlying hereditary or acquired thrombophilia. We prospectively analyzed procoagulant markers and gene mutations in patients with lymphoma (n = 35) and leukemia (n = 10) at diagnosis and over the course of treatment. Global coagulation tests were normal in all patients, as were antithrombin and protein S. Activated protein C resistance caused by the factor V Leiden mutation was found in four patients, one patient had the G20210A mutation of the prothrombin gene, and one patient had protein C deficiency. The most striking findings were sustained very high levels of factor VIII (>150 %) in 30 patients (68 %), which correlated with high von Willebrand factor. An acute phase response in these patients was ruled out by absence of fever and normal IL-6 and -α. Elevated factor VIII is an independent thrombophilic risk factor and may play an etiologic role in thromboembolic complications in patients with malignant lymphoma. Since high von Willebrand factor is most likely caused by endothelial cell injury, an additional, unknown pathophysiological association with malignant lymphoma and acute leukemia is possible.

RESUMEN

OBJECTIVES: To investigate illness perceptions, treatment expectations, and treatment experiences of patients suffering from acute leukaemia in the initial stage of their disease. METHODS: In the first week of treatment we interviewed twelve patients with acute leukaemia using a detailed semi-structured interview guide. To investigate the transcribed interviews we applied methods of qualitative research. Case analyses were assigned to interindividual comparison tables representing the following subject areas: complaints, diagnostics, causes, controllability, treatment experiences, and prognosis. This allowed us to describe similarities and contrasts. RESULTS: Dramatic narrations of overwhelming threat in younger patients are in contrast to downplaying, rationalizing, and factual descriptions especially in elderly patients. Feelings of helplessness and efforts of normalization become apparent. Experiences of visible and sensible physical injury are perceived as threatening. Prognosis is estimated as too positive. Mortal fears are only indirectly indicated. CONCLUSIONS: Our results have practical consequences for both patient education and psycho-oncological training.

RESUMEN

Philadelphia-chromosome (Ph)-positive acute myeloid leukemia (AML) is rare and prognosis is poor with a median survival of six to seven months only. We report on a patient with Ph-positive AML (FAB M2, major BCR/ABL1 mRNA transcript, b2a2), who is in sustained complete cytogenetic and molecular remission for 15 months. Cytarabine-based chemotherapy was discontinued after two courses due to infectious complications. Since the b2a2 transcript was still detectable, imatinib was started with quantitative RT-PCR monitoring. This result is promising and worth further evaluation to establish the role of imatinib in patients with Ph-positive AML.

RESUMEN

We report on a female patient, who, at the age of 63 years, was found to suffer from low-grade MALT-lymphoma localized at her right upper eyelid. At the time of initial diagnosis, clinical staging showed no further organ involvement. Within the following two months, nodular infiltrates occurred in both lungs. Histopathological investigation of the pulmonary lesions showed pulmonary involvement by the low-grade MALT-lymphoma associated with large globular amyloid deposits of lambda-light chain origin. Since the tumor cells of the MALT-lymphoma showed restriction to lambda-light chain the amyloid deposits in this case were interpreted as being related to the MALT-lymphoma.

RESUMEN

The therapy of patients with relapsed or refractory indolent lymphoma relies on the development of new drug combinations. The drugs bendamustine and fludarabine have cytotoxic activity as monotherapy in indolent lymphoma and show synergism in vitro. In this study, we combined both drugs in a multicenter clinical phase I/II trial to evaluate their toxicity and efficacy. Bendamustine was given at 30 or 40 mg/m2/d (dose levels 1 and 2), fludarabine at 30 mg/m2/d, each drug on days 1 to 3. Six cycles were to be given every 4 weeks. A total of 29 patients with relapsed or refractory indolent lymphoma were included in the study. During phase I, 9 patients were treated at dose level 1 and 7 patients at dose level 2. Thirteen patients were added to the study during phase II. Fourteen patients had follicular lymphoma, 11 patients mantle cell lymphoma, 2 patients lymphoplasmocytic and 2 patients nodal marginal zone lymphoma. Median age was 62 years (range 39-74). All patients were in stages III or IV of their disease and had received prior chemotherapy with or without additional radio- or immunotherapy. The dose limiting toxicity was hematotoxicity in all cases and occurred in 3 of 7 evaluable patients at dose level I and in 3 of 7 patients at dose level 2. One patient at dose level 2 died of sepsis in neutropenia with persistent thrombocytopenia. The study was continued at dose level 1 (phase II). Analysis of 19 evaluable patients treated at dose level 1 reveiled hematotoxicity CTC grade III in 47% and grade IV in 26%. Neutropenic fever occurred in 4 patients (21%). On an intent-to-treat basis, 45% or 32% of all patients at dose level 1 reached CR or PR, respectively. Nine of 9 patients with mantle cell lymphoma responded to therapy. The overall response rate was 77%. Eight of 15 responders relapsed after a median follow-up time of 14 months (range 2-43). The major complication of fludarabine in combination with bendamustine is hematotoxicity. Dose level 1 with 30 mg/m2/d of both drugs on days 1 to 3 was defined as the recommended dose. Despite unfavorable prognostic features (histologic subtype, stage of disease, pretreatment) response rates were good with this regimen.
