Patients' and health professionals' understanding of and preferences for graphical presentation styles for individual-level EORTC QLQ-C30 scores.

PURPOSE: To investigate patients' and health professionals' understanding of and preferences for different graphical presentation styles for individual-level EORTC QLQ-C30 scores. METHODS: We recruited cancer patients (any treatment and diagnosis) in four European countries and health professionals in the Netherlands. Using a questionnaire, we assessed objective and self-rated understanding of QLQ-C30 scores and preferences for five presentation styles (bar and line charts, with or without color coding, and a heat map). RESULTS: In total, 548 patients and 227 health professionals participated. Eighty-three percent of patients and 85 % of professionals self-rated the graphs as very or quite easy to understand; this did not differ between graphical presentation styles. The mean percentage of correct answers to questions objectively assessing understanding was 59 % in patients, 78 % in medical specialists, and 74 % in other health professionals. Objective understanding did not differ between graphical formats in patients. For non-colored charts, 49.8 % of patients did not have a preference. Colored bar charts (39 %) were preferred over heat maps (20 %) and colored line charts (12 %). Medical specialists preferred heat maps (46 %) followed by non-colored bar charts (19 %), whereas these charts were equally valued by other health professionals (both 32 %). CONCLUSION: The substantial discrepancy between participants' high self-rated and relatively low objective understanding of graphical presentation of PRO results highlights the need to provide sufficient guidance when presenting such results. It may be appropriate to adapt the presentation of PRO results to individual preferences. This could be facilitated when PROs are administered and presented to patients and health professionals electronically.

Evaluation of electronic patient-reported outcome assessment with cancer patients in the hospital and at home.

BACKGROUND: Patient-reported outcomes (PRO) provide a more comprehensive picture of patients' quality of life than do mere physicians' ratings. Electronic data collection of PRO offers several advantages and allows assessments at patients' homes as well. This study reports on patients' personal internet use, their attitudes towards electronic and web-based PRO assessment (clinic-ePRO and home-ePRO) and the feasibility of these two assessment modes. METHODS: At the Medical University of Innsbruck and Kufstein County Hospital, cancer patients who participated in clinic-ePRO/home-ePRO were asked to complete a comprehensive evaluation form on their personal internet usage, attitudes towards and the feasibility of routine clinic-ePRO/home-ePRO with the Computer-based Health Evaluation System (CHES) software. RESULTS: In total, 113 patients completed the evaluation form for clinic-ePRO (Ø 45 years, SD 14) and 45 patients for home-ePRO (Ø 58 years, SD 10; 33.1 per cent inclusion rate for this sample). Most patients expressed willingness to complete routine clinic-ePRO assessments in the future (94.7 per cent of clinic-ePRO patients and 84.4 per cent of home-ePRO patients) and to discuss their data with attending physicians (82.2 per cent, home-ePRO patients only). Overall, patients preferred the software over paper-pencil questionnaires (67.2 per cent of clinic-ePRO patients and 60 per cent of home-ePRO patients) and experienced it as easy to use. Only a few minor suggestions for improvement were made (e.g. adjustable font sizes). CONCLUSIONS: The use of clinic-ePRO/home-ePRO was in general shown to be feasible and well accepted. However, to be more inclusive in the implementation of clinic-ePRO/home-ePRO, educational programs concerning their particular benefit in oncology practice potentially could enhance patients' attitudes towards, and consequently their acceptance of and compliance with electronic PRO assessments.

Small steps of improvement in small-cell lung cancer (SCLC) within two decades: a comprehensive analysis of 484 patients.

BACKGROUND: It is not clear whether or not the fate of patients suffering from small-cell lung cancer (SCLC) has improved. To better understand the course of disease, we aimed at documenting disease features at initial diagnosis, sequences of therapy modalities and outcome in consecutive patients over two decades. We postulated that SCLC patients might have benefitted from refined diagnosis and treatment options during the last decade. METHODS: All SCLC cases diagnosed at the Innsbruck University Hospital and associated institutions between 1991 and 2011 have been documented in detail in accordance with a prespecified protocol. RESULTS: A total of 484 patients diagnosed with SCLC were followed. The most important symptoms at initial diagnosis were cough, dyspnea and tumor pain in 55%, 51% and 44%, respectively. Patients who were operated during early stage of disease (n = 26) had a favorable 5-year, relapse-free survival (74%). A total of 112 patients with locally advanced disease were treated by radiochemotherapy in curative intent (RCT), and achievement of CR offered a chance of long term overall survival (OS), reaching 44% after 10-years. In the palliative setting (median OS in 304 evaluable patients, 9.7 months), a therapeutic progress in the more recent decade could not be observed. Parameters independently associated with favorable OS were: response to therapy and prophylactic brain irradiation in patients with RCT; and response, age < 70 years and absence of LDH elevation in the palliative setting. CONCLUSIONS: In this comprehensive view on SCLC, the findings on symptomatology, comorbidity, and spectrum of treatments may help to better understand individual courses of the disease. Overall, modern medicine failed to translate into substantial benefit of SCLC patients, except in patients in locally advanced disease receiving multimodal therapy.

Alemtuzumab in chronic lymphocytic leukemia: final results of a large observational multicenter study in mostly pretreated patients.

This retrospective study evaluated the benefit of alemtuzumab monotherapy in unselected patients with advanced B-cell chronic lymphocytic leukemia (CLL) and prolymphocytic leukemia (B-PLL) to definitely describe the impact of this antibody in clinical routine use. Data were collected from 208 consecutive, mainly pretreated, patients with CLL (n = 202), and B-PLL (n = 6) who had received alemtuzumab. Response, progression-free survival (PFS), and overall survival (OS) in various settings were assessed, and toxicities were documented. In these routine patients, a comparably low cumulative dose of alemtuzumab (median, 403 mg) was applied. In CLL, overall response rate was 32 %, and various pre-therapeutic parameters were predictive for inferior response, among them, the prior administration of ≥3 therapy lines (P < 0.001), refractoriness to fludarabine (P = 0.002), and bulky lymphadenopathy (P = 0.003). PFS and OS after start of alemtuzumab were 6.2 and 21.0 months, respectively. Bulky lymphadenopathy was the prominent risk factor for both inferior PFS (P < 0.001) and OS (P = 0.002). In B-PLL, four patients experienced a fatal outcome, whereas two patients had some benefit with alemtuzumab. The main adverse effects were CMV reactivation (20 %) and a broad spectrum of infections, which together were the main reasons for treatment interruption and/or premature termination. In conclusion, alemtuzumab administered even at low dose levels was effective but overall considerably toxic in routine CLL patients. We emphasize that alemtuzumab remains an important therapeutic option in subsets of CLL patients.

Quality of life during chemotherapy in lung cancer patients: results across different treatment lines.

BACKGROUND: Most lung cancer patients are diagnosed at an advanced disease stage and predominantly receive palliative treatment, which increasingly consists of several chemotherapy lines. We report on patients' quality of life (QOL) to gain knowledge on QOL during and across multiple lines of chemotherapy. This includes patients with (neo)adjuvant therapy up to 3rd or above line palliative chemotherapy. METHODS: Lung cancer patients receiving outpatient chemotherapy at the Kufstein County Hospital completed an electronic version of the EORTC QLQ-C30. Linear mixed models were used for statistical analysis. RESULTS: One hundred and eighty seven patients were included in the study. Surprisingly, irrespective of the chemotherapy line patients reported stable QOL scores during treatment. None of the calculated monthly change rates attained clinical significance, referring to established guidelines that classify a small clinical meaningful change as 5 to 10 points. According to treatment line, 3rd or above line palliative chemotherapy was associated with the worst QOL scores, whereas patients undergoing (neo)adjuvant or 1st line palliative chemotherapy reported fairly comparable QOL. CONCLUSION: The essential finding of our study is that all QOL aspects of the EORTC QLQ-C30 questionnaire remained unchanged during each chemotherapy line in an unselected population of lung cancer patients. Between treatment lines pronounced differences were found, indicating that later palliative chemotherapy lines are associated with higher QOL impairments. These changes in QOL may not primarily be related to the treatment, but rather refer to impairments due to disease progression and may be partly due to a consequence of the prior therapies.

Preoperative chemotherapy with cisplatin and docetaxel followed by surgery and clip-oriented postoperative chemoradiation in patients with localized gastric or gastroesophageal junction adenocarcinoma: results from a phase II feasibility study.

BACKGROUND: We conducted a phase II feasibility study using preoperative chemotherapy with cisplatin and docetaxel followed by surgical resection and postoperative chemoradiation in patients with gastric or gastroesophageal cancer. METHODS: Preoperative chemotherapy (two or three cycles) consisted of 50 mg/m(2) docetaxel and 50 mg/m(2) cisplatin. Surgical resection was planned 4 weeks after the last chemotherapy cycle. Patients underwent postsurgical chemoradiation, receiving a total dose of 39.6 Gy and 5-fluorouracil (5-FU) continuous infusion (350 mg/m(2)/day). The primary end-points were feasibility, overall response rate and R0 resectability rate after preoperative chemotherapy. The secondary end-points were tolerability, treatment-associated complications, disease-free survival and overall survival. RESULTS: Between 2002 and 2004, 15 patients were enrolled in this study. After neoadjuvant treatment, two patients (13%) experienced progressive disease, four patients (27%) showed partial remission and nine patients (60%) showed stable disease. In 11 patients (73%) R0 resectability could be achieved. Six of these patients (54%) were able to undergo postoperative chemoradiation. Notably, five (83%) of these patients were disease free and alive at median follow-up of 72 months. Chemotherapy-associated neutropaenia and neutropaenic fever, anastomotic dehiscence, pulmonary embolism and acute pancreatitis were observed. CONCLUSIONS: The combination of preoperative chemotherapy and postoperative chemoradiation is feasible in a significant subset of gastric cancer patients.

Clinical outcome of pretreated B-cell chronic lymphocytic leukemia following alemtuzumab therapy: a retrospective study on various cytogenetic risk categories.

BACKGROUND: Patients with B-cell chronic lymphocytic leukemia (CLL) with 17p deletion respond poorly to chemotherapy. This retrospective study evaluated the benefit of alemtuzumab monotherapy in unselected patients with advanced CLL in the various cytogenetic subgroups. PATIENTS AND METHODS: Data were collected from 105 consecutive, pretreated, cytogenetically defined patients who had received alemtuzumab. Response, progression-free survival (PFS), and overall survival (OS) were assessed. RESULTS: The hierarchic incidence of cytogenetic abnormalities was: 13q deletion (as sole abnormality), 18%; trisomy 12, 13%; 11q deletion, 19%; 17p deletion, 33%; and none of these, 16%. Overall response rate (ORR) was 43% in the total cohort and 49% in the subgroup of 17p-deleted patients (n = 35). From the start of alemtuzumab monotherapy, median PFS in the total cohort and in the subgroup of 17p-deleted patients was 7.0 and 7.1 months, respectively. Median OS in the total cohort and in 17p-deleted patients was 32.8 and 19.1 months, respectively. The poor-risk group of patients with CLL (i.e. fludarabine resistant, 17p deletion; n = 20) showed encouraging ORR, PFS, and OS (35%, 7.0 and 19.2 months, respectively). CONCLUSIONS: Alemtuzumab was effective in treating patients with CLL across the cytogenetic categories evaluated, but there were differences. In patients with CLL with 17p deletion quite favorable ORR, PFS, and OS were achieved.

A new approach to combining clinical relevance and statistical significance for evaluation of quality of life changes in the individual patient.

OBJECTIVE: Empirical investigation of formerly proposed criteria for relevant changes of health-related quality of life (QOL) regarding their use for monitoring changes in the individual patient. Suggestion of a new criterion trying to overcome the drawbacks of former criteria. STUDY DESIGN AND SETTING: QOL data were collected longitudinally in 160 cancer patients receiving chemotherapy at an oncological outpatient unit, giving rise to a total of 975 QOL assessments. QOL was measured using the European Organization on Research and Treatment of Cancer Quality of Life Core Questionnaire. Several formerly suggested criteria of relevant change (distribution based, anchor based) were compared in terms of both prevalence and statistical significance of the resulting relevant changes. RESULTS: When considering criteria of relevant change suggested in the literature, high proportions (average: 42.3-48.3%) of reputedly relevant changes were found. The majority of these changes (average: 55.8-62.2%) were statistically insignificant. Combination of an increased threshold for clinical relevance with the concept of statistical significance resulted in a more meaningful change criterion. CONCLUSION: Formerly recommended thresholds of relevant change in QOL appear to be unduly low when focusing on the individual patient. A modified criterion is therefore suggested for this case. However, more research is needed for validation and refinement of the proposed criterion.

Biweekly oxaliplatin and irinotecan chemotherapy in advanced gastric cancer. A first-line multicenter phase II trial of the Arbeitsgemeinschaft Medikamentöse Tumortherapie (AGMT).

BACKGROUND: The aim of the study was to evaluate the feasibility and efficacy of an outpatient oxaliplatin/irinotecan chemotherapy in chemonaive patients suffering from unresectable gastric cancer. MATERIALS AND METHODS: Biweekly oxaliplatin (85 mg/m2) and irinotecan (125 mg/m2) was chosen since it has been shown previously in colorectal cancer that oxaliplatin (85 mg/m2) is superior to a lower dose and toxicity of irinotecan is much lower if given fractionated. The irinotecan dose below the maximum tolerated dose takes into consideration concerns about increased toxicity in gastric cancer patients. RESULTS: Forty-three patients with histologically proven gastric adenocarcinoma and no previous palliative chemotherapy were selected. WHO grade 3 and 4 toxicities included neutropenia in 2/43 patients, anemia in 3/43 patients, nausea in 2/43 patients and diarrhea in 4/43 patients. Response rates were assessable in 38 patients as follows: complete response in three patients (8%), partial response in 19 (50%), stable disease in 11 (29%), and progressive disease in 5 patients (13%). The median time-to-progression was 53 months and median overall survival was 9.5 months. CONCLUSION: The outpatient combination of biweekly oxaliplatin/irinotecan was well tolerated and showed a response rate within the range of other first-line combination therapies. The favorable toxicity profile, however, renders oxaliplatin/irinotecan as an alternative first-line regimen.

A randomized study comparing interferon (IFN alpha) plus low-dose cytarabine and interferon plus hydroxyurea (HU) in early chronic-phase chronic myeloid leukemia (CML).

This multicenter randomized phase III study was designed to compare the efficacy and toxicity of IFN alpha-2c (3.5 MU/d) in combination with either araC (10 mg/m(2) d1-10) or hydroxyurea (HU: 25 mg/kg per day) in newly diagnosed CML patients. A total of 114 patients were randomized. Following a median observation period of 36 (range 1-73) months the major cytogenetic response rates were 25 and 27% and the 4-year survival probabilities 62.5 and 63% for the araC and HU group, respectively. While the overall toxicity profile was comparable between both groups, patients in the HU arm exhibited a slightly higher degree of WHO grades 3 and 4 non-hematological toxicities.

Docetaxel monotherapy in heavily pretreated metastatic breast cancer: a multicenter, community-based feasibility trial.

PURPOSE: To evaluate the efficacy and safety of docetaxel in heavily pretreated and anthracycline-resistant patients with metastatic breast cancer in an outpatient setting. PATIENTS AND METHODS: Between February 1996 and June 1998, 98 consecutive patients who had progressed during or relapsed following prior anthracycline-containing chemotherapy were enrolled into the trial. Docetaxel was administered at a dose of 100 mg/m2 by intravenous infusion every 3 weeks. The administration of colony-stimulating factors was at the discretion of the attending physician. Premedication with dexamethasone was mandatory for all patients. RESULTS: Of the 98 patients, 93 were evaluable for toxicity and response. Patients had received two palliative regimens (median, range 1-5) prior to docetaxel treatment. The most frequent toxicity observed was leukopenia grade III and IV (WHO grading system) which occurred in 47% of patients (grade IV only in 14%). Except for alopecia grade III (64% of patients), nonhematologic side effects grade III-IV were rare (1-7% of patients) and included nausea, stomatitis, diarrhea, peripheral neuropathy, fluid retention and pulmonary toxicities. There were no treatment-related deaths. Objective responses occurred in 40% of patients (CR 6%, PR 34%), and stable disease in 38% of patients. The median duration of response was 5.3 months (range 0.7-18.1 months) while the median survival was 15 months (range 2 36 months). CONCLUSION: Docetaxel is a highly active agent in patients with anthracycline-resistant metastatic breast cancer, even in heavily pretreated patients, with moderate toxicity.

Treatment of patients with advanced chronic myelogenous leukemia with interferon-alpha-2b and continuous oral cytarabine ocfosfate (YNK01): a pilot study.

The efficacy of continuous oral cytarabine ocfosfate (YNK01) (300 mg/day) in combination with interferon alpha (IFNalpha, 5x10(6) IU/day) was evaluated in patients with advanced chronic myelogenous leukemia, who previously failed to respond to IFNalpha-based therapies. Dose escalations up to 900 mg YNK01 were allowed in patients who failed to respond. In view of our results, four patients developed a complete hematological response after YNK01 was started. Among those who initially responded to YNK01, one complete cytogenetic response was achieved 18 months later. Although the data are preliminary, this is the first study showing that continuous administration of YNK01 along with IFNalpha is effective in patients with advanced chronic myelogenous leukemia.

Recombinant human granulocyte-macrophage colony-stimulating factor applied locally in low doses enhances healing and prevents recurrence of chronic venous ulcers.

BACKGROUND: Chronic venous leg ulcers have a major medical and economic impact on the elderly worldwide. Healing of the large ulcers (>10 cm2) occurs only in two-thirds of the patients and reulceration of healed ulcers recurs in one-third within 1 year. Because both healing and relapse rate influence greatly a patient's quality of life and the overall cost of treatment, every effort should be made to improve these two parameters. OBJECTIVE: To determine the safety and efficacy of topical low-dose recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF) for the treatment of venous ulcers, and to document any improvement in healing rates. METHODS: Thirty-eight patients (29 women, 9 men; median age, 74 years) with chronic venous insufficiency were treated with topical rhu GM-CSF (5 microg/mL 0.9% sodium chloride solution), followed by application of a compression dressing. All subjects were treated as outpatients. RESULTS: Complete healing was observed in 47 of the 52 ulcers (90.4%). The average healing time was 19 weeks. No systemic or local side-effects from the therapy were observed. Nine chronic ulcers, previously refractory to conventional treatment (pretreatment for more than 46 weeks), showed the same response rate (9/8, or 88.9%) and healing time (mean, 19 weeks). After 40 months, no reulceration of the healed ulcers was observed, but two patients developed new ulcers on the same leg. Healing remained stable, with excellent cosmetic results. CONCLUSIONS: In this first study, topically applied low-dose rhu GM-CSF was a safe treatment for chronic venous leg ulcers. Healing rates were significantly increased and relapse rates were minimal.

Efficacy and toxicity of 2-Chlorodeoxyadenosine (Cladribine)--2 h infusion for 5 days--as first-line treatment for advanced low grade non-Hodgkin's lymphoma.

2-Chlorodeoxyadenosine (Cladribine) is a new purine analogue with high activity in pretreated low grade non-Hodgkin's lymphoma (NHL). To evaluate the efficacy of this drug in untreated patients with advanced NHL, we performed a prospective multicentre trial. Cladribine (0.12 mg/kg) was administered intravenously daily for 5 consecutive days in an out-patient setting. The treatment was repeated every 28 days for four cycles. Included were patients with a histological diagnosis of low grade NHL according to the Kiel classification and stage III or IV disease. Stage II patients were included when radiotherapy had failed. 55 patients were entered into the study. 50 patients were evaluable. The remission rate was 44/50 (88%; 95% confidence interval 82-100%), including complete remissions (CR) in 14 (28%) patients. Only 2 patients showed progression while on Cladribine treatment. The estimated overall survival, and time to treatment failure (TTF) were 85% and 51%, respectively, after a median observation time of 92 weeks. 11 (22%) patients showed grade 3 or 4 toxicity according to the WHO grading. Haematological toxicity was responsible for 86% of the overall toxicity and 100% of grade 3 and 4 toxicity. 7 patients (14%) had an infection, two of which were opportunistic. 12 (24%) patients did not experience any toxicity during the treatment. The results of this study clearly demonstrate the safety and considerable activity of this regimen. Cladribine is very effective even at lower doses than have been used so far.

Cytokine priming of the granulocyte respiratory burst in myelodysplastic syndromes.

Increased susceptibility to infections in patients with myelodysplastic syndromes (MDS) is thought to be due to neutropenia as well as functional abnormalities of neutrophils. In the present study we examined the effect of two different stimulants (fMLP, PMA) and three cytokines (alphaTNF, G-CSF and GM-CSF), both singly and in combination on granulocyte (RB) in 25 MDS patients compared to seven healthy controls. Single fMLP and PMA-stimulation showed similar results for both groups. Preincubation with cytokines enhanced fMLP-stimulated RB in most MDS patients and controls, but in patients to a significantly lesser extent when compared to the control group (p < or = 0,05). Combinations of alphaTNF + GM-CSF and alphaTNF + G-CSF were highly synergistic in priming fMLP-stimulated burst in both groups. But again, as with the single cytokine priming this effect was markedly reduced in MDS patients compared to controls (p < or = 0,05). A specific priming defect for one of the cytokines or a cytokine combination could not be demonstrated. Serum alphaTNF levels were measured in 18 and neutrophil alkaline phosphatase (NAP) index in 23 patients. Results did not correlate with variations of the RB in MDS patients. We conclude that reduced alphaTNF, GM-CSF and G-CSF priming of granulocyte RB is a frequent finding in MDS and may contribute to the enhanced susceptibility to bacterial infections.

Oxidative burst of neutrophils in patients with rheumatoid arthritis: influence of various cytokines and medication.

OBJECTIVE: Toxic oxygen products are believed to be implicated in tissue damage in some complex-mediated diseases such as rheumatoid arthritis. In the present study we compared the superoxide (O2) production of polymorphonuclear leukocytes (PMNs) in 21 patients with rheumatoid arthritis (RA) with that of 9 healthy controls, examining the effect of different stimulants and cytokines on the oxidative burst (OB). Since many drugs used in the treatment of RA may alter O2 metabolism, the effects of antirheumatic medication were also studied. METHODS: Generation of superoxide anions was analysed by a flow cytometric method, using the fluorochrome dihydro-rhodamine. As stimulants for OB, we used N-formyl-methionyl-leucyl-phenylalanine (fMLP), which acts via a membrane receptor, and phorbol-myristate acetate (PMA), which acts in a membrane receptor-independent manner. As preactivating substances, TNF-alpha, G-CSF and GM-CSF were applied. RESULTS: In RA patients under treatment with antirheumatic medication, fMLP-induced OB (+/- cytokines) was significantly reduced, while O2 production after stimulation with PMA was similar compared to controls. GM-CSF showed the highest level of preactivation in controls, whereas in RA patients TNF-alpha proved to be most potent. In both controls and RA patients, a combination of GM-CSF or G-CSF with TNF-alpha further enhanced OB. No correlation between OB and clinical data or treatment could be established in RA patients. CONCLUSIONS: There is a reduced cytokine priming capacity for OB in RA patients under antirheumatic medication in spite of the presence of an intact enzyme system of OB. Antirheumatic medication combining multiple drugs capable of decreasing OB might effectively modulate oxidative metabolism.

An unusual case of a splenic gamma/delta T-cell lymphoma with angiocentric tendency and haemophagocytic syndrome.

We report here an unusual post-thymic T-cell neoplasia of the spleen associated with a rapidly progressive haemophagocytic syndrome. The lymphoma was classified as a medium- to large sized pleomorphic T-cell lymphoma with angiocentric tendency (CD3+, CD43+, CD45RO+ CD45+). Clonality was confirmed by PCR and revealed rearrangement of the T-cell receptor gamma chain. Serological tests excluded a recent EBV infection and in situ hybridization with the EBER probe was negative. Haemophagocytic syndrome was the initial finding in an otherwise symptomless patient and this deteriorated with progression of the T-cell malignancy. Both, the T-cell lymphoma and the haemophagocytic syndrome remained unaffected by chemotherapy. Splenic gamma/delta T-cell lymphoma associated with haemophagocytosis is an uncommon entity which has until now not been widely recognized.
