RESUMEN
BACKGROUND: Dignity is a basic principle of palliative care and is intrinsic in the daily practice of professionals assisting individuals with incurable diseases. Dignity Therapy (DT) is a short-term intervention aimed at improving the sense of purpose, meaning and self-worth and at reducing the existential distress of patients facing advanced illness. Few studies have examined how DT works in countries of non-Anglo Saxon culture and in different real-life settings. Moreover, most studies do not provide detailed information on how DT is conducted, limiting a reliable assessment of DT protocol application and of its evaluation procedure. The aim of this study was to assess the feasibility and acceptability of a nurse-led DT intervention in advanced cancer patients receiving palliative care. METHOD: This is a mixed-method study using before and after evaluation and semistructured interviews. Cancer patients referred to a hospital palliative care unit were recruited and provided with DT. The duration of sessions, and timeframes concerning each step of the study, were recorded, and descriptive statistical analyses were performed. The patients' dignity-related distress and feedback toward the intervention were assessed through the Patient Dignity Inventory and the Dignity Therapy Patient Feedback Questionnaire, respectively. Three nurses were interviewed on their experience in delivering the intervention, and the data were analyzed qualitatively. RESULTS: A total of 37/50 patients were enrolled (74.0%), of whom 28 (75.7%) completed the assessment. In 76.7% of cases, patients completed the intervention in the time limit scheduled in the study. No statistically significant reduction in the Patient Dignity Inventory scores was observed at the end of the intervention; most patients found DT to be helpful and satisfactory. Building opportunities for personal growth and providing holistic care emerged among the facilitators to DT implementation. Nurses also highlighted too great of a time commitment and a difficult collaboration with ward colleagues among the barriers. CONCLUSIONS: Our findings strongly support the acceptability, but only partially support the feasibility, of nurse-led DT in advanced cancer patients in a hospital setting. Further research is needed on how to transfer the potential benefits of DT into clinical practice. TRIAL REGISTRATION: Retrospectively registered on ClinicalTrial.gov NCT04738305 .

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening microangiopathy with a heterogeneous and largely unpredictable course. It is caused by ADAMTS13 deficiency, that can be either congenital or due to anti-ADAMTS13 autoantibodies development. ADAMTS13 deficiency is necessary but not always sufficient to cause acute clinical manifestations and trigger factors may be needed. We report the case of a woman diagnosed with congenital TTP in her adulthood, presenting with anti-ADAMTS13 autoantibodies in acute phase during ticlopidine consumption. Noteworthy, the two ADAMTS13 mutations identified in this patient are novel: one is a splice-site mutation located in intron 11 (c.1308+2_5delTAGG) and the other is a point missense mutation in exon 29 (c.4184T>C leading to p.Leu1395Pro substitution). Since congenital TTP is an extremely rare disease and drug-induced TTP is an uncommon side effect of treatment with ticlopidine, the simultaneous occurrence of both mechanisms of disease in one patient is exceptional. This case represents TTP as a multifactorial disease, with ADAMTS13 genetic abnormality and environmental exposures acting together in determining individual clinical phenotype.

In a randomized, phase 3 study, superior complete/near-complete response (CR/nCR) rates and extended progression-free survival were demonstrated with bortezomib-thalidomide-dexamethasone (VTD) versus thalidomide-dexamethasone (TD) as induction therapy before, and consolidation after, double autologous stem cell transplantation for newly diagnosed myeloma patients (intention-to-treat analysis; VTD, n = 236; TD, n = 238). This per-protocol analysis (VTD, n = 160; TD, n = 161) specifically assessed the efficacy and safety of consolidation with VTD or TD. Before starting consolidation, CR/nCR rates were not significantly different in the VTD (63.1%) and TD arms (54.7%). After consolidation, CR (60.6% vs 46.6%) and CR/nCR (73.1% vs 60.9%) rates were significantly higher for VTD-treated versus TD-treated patients. VTD consolidation significantly increased CR and CR/nCR rates, but TD did not (McNemar test). With a median follow-up of 30.4 months from start of consolidation, 3-year progression-free survival was significantly longer for the VTD group (60% vs 48% for TD). Grade 2 or 3 peripheral neuropathy (8.1% vs 2.4%) was more frequent with VTD (grade 3, 0.6%) versus TD consolidation. The superior efficacy of VTD versus TD as induction was retained despite readministration as consolidation therapy after double autologous transplantation. VTD consolidation therapy significantly contributed to improved clinical outcomes observed for patients randomly assigned to the VTD arm of the study. The study is registered at www.clinicaltrials.gov as #NCT01134484.

We performed a molecular study aimed at identifying a gene expression profile (GEP) signature predictive of attainment of at least near complete response (CR) to thalidomide-dexamethasone (TD) as induction regimen in preparation for double autologous stem cell transplantation in 112 younger patients with newly diagnosed multiple myeloma. A GEP supervised analysis was performed on a training set of 32 patients, allowing to identify 157 probe sets differentially expressed in patients with CR versus those failing CR to TD. We then generated an eight-gene GEP signature whose performance was subsequently validated in a training set of 80 patients. A correct prediction of response to TD was found in 71 % of the cases analyzed. The eight genes were downregulated in patients who achieved CR to TD. Comparisons between post-autotransplantation outcomes of the 44 non-CR-predicted patients and of the 36 CR-predicted patients showed that this latter subgroup had a statistically significant benefit in terms of higher rate of CR after autotransplant(s) and longer time to progression, event-free survival, and overall survival. These results can be an important first step to identify at diagnosis those patients who will respond more favourably to a particular treatment strategy.

BACKGROUND: Defibrotide is a novel orally bioavailable polydisperse oligonucleotide with anti-thrombotic and anti-adhesive effects. In SCID/NOD mice, defibrotide showed activity in human myeloma xenografts. This phase I/II study was conducted to identify the most appropriate dose of defibrotide in combination with melphalan, prednisone and thalidomide in patients with relapsed and relapsed/refractory multiple myeloma, and to determine its safety and tolerability as part of this regimen. DESIGN AND METHODS: This was a phase I/II, multicenter, dose-escalating, non-comparative, open label study. Oral melphalan was administered at a dose of 0.25 mg/kg on days 1-4, prednisone at a dose of 1.5 mg/kg also on days 1-4 and thalidomide at a dose of 50-100 mg/day continuously. Defibrotide was administered orally at three dose-levels: 2.4, 4.8 or 7.2 g on days 1-4 and 1.6, 3.2, or 4.8 g on days 5-35. RESULTS: Twenty-four patients with relapsed/refractory multiple myeloma were enrolled. No dose-limiting toxicity was observed. In all patients, the complete response plus very good partial response rate was 9%, and the partial response rate was 43%. The 1-year progression-free survival and 1-year overall survival rates were 34% and 90%, respectively. The most frequent grade 3-4 adverse events included neutropenia, thrombocytopenia, anemia and fatigue. Deep vein thrombosis was reported in only one patient. CONCLUSIONS: This combination of melphalan, prednisone and thalidomide together with defibrotide showed anti-tumor activity with a favorable tolerability. The maximum tolerated dose of defibrotide was identified as 7.2 g p.o. on days 1-4 followed by 4.8 g p.o. on days 5-35. Further trials are needed to confirm the role of this regimen and to evaluate the combination of defibrotide with new drugs.

BACKGROUND: Venous thromboembolism (VTE) is a major complication of myeloma therapy recently observed with the increasing use of up-front thalidomide and dexamethasone (thal-dex). The pathogenesis of thal-induced VTE is not well recognized, and the role of prothrombotic factors, especially of thrombophilic abnormalities, is not yet determined. MATERIAL AND METHODS: Two hundred and sixty-six patients with newly diagnosed multiple myeloma (MM) were primarily treated with thal-dex in preparation for subsequent high-dose therapy and autologous stem-cell transplantation. Out of these 266 patients, 190 were evaluated for thrombophilic alterations at baseline, and 125 of them were also re-assessed after thal-dex therapy. RESULTS: The presence of genetic thrombophilic polymorphisms among patients with MM was superimposable to that of normal controls and was associated with a twofold increase in the relative risk of VTE. aAPCR and elevated factor VIII levels were frequent, albeit transient, alterations and were not associated with a significant increase in the risk of VTE. Two hundred and forty-six patients received a thromboprophylaxis with fixed low-dose warfarin (1.25 mg/day) during thal-dex therapy. Of these patients (or 10.6%), 26 had symptomatic VTE events. Their patients-years rate of VTE (35.5%) was significantly lower in comparison with the 86.2% rate recorded among the first 19 patients who initially entered the study and did not receive any kind of thromboprophylaxis (P = 0.043). CONCLUSIONS: On the basis of these data, a baseline thrombophilic work up is not recommended in patients with receiving up-front thal-dex. For these patients, fixed low-dose warfarin may be a valuable prophylaxis against VTE.

PURPOSE: To describe the clinical, morphologic, and immunohistochemical features of a case of paranasal natural killer/T-cell lymphoma (NKTL) with ocular involvement. CASE REPORT: In March 2005 the patient presented with a maxillary sinusitis and upper nasal obstruction. In July she underwent a nasal computed tomography (CT) scan and multiple biopsies of the granulomatous tissue in the nasal fossae. The diagnosis was NK/T non-Hodgkin's lymphoma nasal type, stage IV A. Afterwards she presented anterior uveitis. In September after the diagnosis of lymphoma the patient underwent a bone marrow biopsy and thoracic and abdominal CT scan. An ophthalmic examination including visual acuity assessment and fundoscopic examination was made. In October she started chemotherapy cycles. Maxillary CT scan and ophthalmic examinations were performed during the cycles. In January 2006 after severe recurrences of panuveitis a diagnostic vitrectomy was performed. RESULTS: A diagnosis of T-lymphoma cells in the vitreous was made; the tumor was most likely originating from her paranasal NKTL. The condition of the patient deteriorated rapidly and she expired on February 2006. CONCLUSIONS: Nasal and paranasal sinus lymphomas are rare, but aggressive diseases with a tendency to invade tissues and spread to CNS, including the eye. Ocular manifestations prior to systemic ones may be useful to monitor the response to therapy.

Over a period of 28 months, we observed five cases of osteonecrosis of the jaw (ONJ) in cancer patients treated with bisphosphonates (BP) at our institution. This prompted us to undertake a retrospective, multicenter study to analyse the characteristics of patients who exhibited ONJ and to define the frequency of ONJ in multiple myeloma (MM). We identified 35 cases in Gruppo Italiano Studio Linfomi centers during the period 2002 - 05. The median time from cancer diagnosis to the clinical onset of ONJ was 70 months. In these 35 cases of ONJ, 24 appeared 20 - 60 months after starting BP treatment. The time for the onset of ONJ was significantly shorter for patients treated with zoledronic acid alone than for those treated with pamidronate followed by zoledronic acid. The frequency of ONJ in the MM group during the study period was 1.9%, although the nature of the present study may have resulted in an underestimation of ONJ cases. Our analysis strongly suggested an association between the use of BP and the occurrence of ONJ, although we were unable to identify any definite risk factors with a retrospective study. The most frequently ONJ-associated clinical characteristics were chemotherapy treatment, steroid treatment, advanced age, female sex, anemia, parodonthopaties/dental procedures and thalidomide (in the case of MM patients).

BACKGROUND AND OBJECTIVES: Cryptococcosis is an important cause of morbidity and death in immunocompromised patients. The aim of this study was to evaluate clinical and laboratory characteristics, and outcome of patients with cryptococcosis complicating hematologic diseases. DESIGN AND METHODS: This was a retrospective study, conducted over a ten-year period (1993-2002) in 21 hematology divisions, in tertiary care or university hospitals. RESULTS: This study evaluated 17 patients with hematologic diseases who developed cryptococcosis. Possible risk factors recognized before the onset of the infection were: administration of steroids for the underlying malignancy (6 patients), diabetes mellitus (4 patients), cutaneous lesions (2 patients) and autoimmune disease, hepatic cirrhosis, chronic renal failure and exposure to pigeons (1 patient each). Five patients received prophylaxis, consisting of fluconazole in 2 cases. Fever, neurological and respiratory signs developed according to the primary sites of infection (5 blood, 5 central nervous system, 4 lung, and 1 each in gut, skin and mouth). Diagnosis was made by positive microbiological culture, antigen detection in serum or cerebrospinal fluid, or polymerase chain reaction. All patients started specific treatment (fluconazole, 7 patients; amphotericin-B deoxycolate or liposomal amphotericin-B, 10 patients). Two patients died from cryptococcosis within 30 days after diagnosis. INTERPRETATION AND CONCLUSIONS: Cryptococcosis in patients with hematologic malignancies is a rare complication. In neutropenic patients, it is less fatal than other fungal infections (i.e. aspergillosis or candidemia). Specific treatment, started promptly, positively influences the outcome.

Several trials comparing the efficacy of standard melphalan and prednisone (MP) therapy with MP plus thalidomide (MPT) in elderly patients with multiple myeloma (MM) have been reported, with inconsistent results. The primary goal of our study was to evaluate the efficacy and toxicity of MP versus MPT in newly diagnosed patients with MM who were transplant-ineligible or over age 65. A total of 135 patients were enrolled. Either minimal response or better or partial response or better were more frequent with MPT treatment (pâ=â0.001). After a median follow-up of 30 months, median progression-free survival (PFS) and overall survival (OS) were 33 and 52 months for MPT versus 22 and 32 months for MP, respectively. The comparison showed a significant advantage for MPT versus MP in PFS (pâ=â0.02) and only a trend for OS (pâ=â0.07). Severe adverse events were observed more frequently with MPT. In conclusion, our results show an improved activity of MPT at a cost of increased toxicity. We believe that MPT can be considered one of the new standard of care for elderly or transplant-ineligible patients with MM.

PURPOSE: We performed a prospective, randomized study of single (arm A) versus double (arm B) autologous stem-cell transplantation (ASCT) for younger patients with newly diagnosed multiple myeloma (MM). PATIENTS AND METHODS: A total of 321 patients were enrolled onto the study and were randomly assigned to receive either a single course of high-dose melphalan at 200 mg/m2 (arm A) or melphalan at 200 mg/m2 followed, after 3 to 6 months, by melphalan at 120 mg/m2 and busulfan at 12 mg/kilogram (arm B). RESULTS: As compared with assignment to the single-transplantation group (n = 163 patients), random assignment to receive double ASCT (n = 158 patients) significantly increased the probability to attain at least a near complete response (nCR; 33% v 47%, respectively; P = .008), prolonged relapse-free survival (RFS) duration of 18 months (median, 24 v 42 months, respectively; P < .001), and significantly extended event-free survival (EFS; median, 23 v 35 months, respectively; P = .001). Administration of a second transplantation and of novel agents for treating sequential relapses in up to 50% of patients randomly assigned to receive a single ASCT likely contributed to prolong the survival duration of the whole group, whose 7-year rate (46%) was similar to that of the double-transplantation group (43%; P = .90). Transplantation-related mortality was 3% in arm A and 4% in arm B (P = .70). CONCLUSION: In comparison with a single ASCT as up-front therapy for newly diagnosed MM, double ASCT effected superior CR or nCR rate, RFS, and EFS, but failed to significantly prolong overall survival. Benefits offered by double ASCT were particularly evident among patients who failed at least nCR after one autotransplantation.

BACKGROUND AND OBJECTIVES: Few therapeutic options are presently available for patients with multiple myeloma (MM) who relapse after autologous or allogeneic stem cell transplantation, or for patients who are refractory to conventional chemotherapy and not eligible for salvage high-dose therapy. Thalidomide, a glutamic acid derivative with anti-angiogenic properties, has been recently proposed as an effective therapy for patients with advanced refractory disease. The aim of this study was to evaluate the activity of thalidomide in a large series of MM patients. DESIGN AND METHODS: From October 1999 to January 2001, 65 patients (46 males/19 females) from 8 Italian institutions were treated with thalidomide. Twenty-six patients had relapsed after autologous stem cell transplantation, either single (n = 12) or double (n= 12); 38 patients had shown disease progression after >= 2 lines of conventional chemotherapy, 2 patients had relapsed after allotransplant, one single patient had not received previous treatment. Sixty-one (93.8%) patients were in stage III, median b2 microglobulin was 2.9 mg/L, and median bone marrow plasma cell infiltration was 50%. Thalidomide was initially administered at a dose of 100 mg/day; if well tolerated, the dose was to be increased serially by 200mg every other week to a maximum of 800 mg/day. RESULTS: The median administered dose of thalidomide was 400 mg/day. WHO grade > II toxic effects were constipation (52%), lethargy (34%), skin rash (11%), peripheral neuropathy (14%) and leukopenia (3%). Sixty patients are presently evaluable for response; of these, 17 (28.3%) showed > or = 50% reduction in serum or urinary M protein concentration and 11 (18.3%) showed > or = 25% tumor reduction, for a total response rate averaging 46.6%. After a median of 8 months' follow-up, 15/28 patients are alive and progression-free (at 2 to 16 months), 12 patients have relapsed, and 1 patient died of pulmonary edema while still in partial remission. Among pre-treatment variables that were analyzed for their potential relationship with tumor response, only the concentration of vascular endothelial growth factor (VEGF) in the conditioned media obtained upon culture of bone marrow plasma cells was statistically significant. Plasma cells from patients who responded favorably to thalidomide secreted a significantly lower amount of VEGF than plasma cells from resistant patients (126.45 165 pg/mL vs 227.11 70 pg/mL, p=0.04). INTERPRETATION AND CONCLUSIONS: These data confirm that thalidomide is active in patients with advanced relapsed/refractory MM and represent the basis for ongoing clinical trials aimed at testing the role of this drug as front line therapy for newly diagnosed disease.

A retrospective survey was conducted over a 10-year period (1990-99) among 52 haematology divisions in order to evaluate the clinical and laboratory characteristics and outcome of patients with proven Pneumocystis carinii pneumonia (PCP) complicating haematological diseases. The study included 55 patients (18 with non-Hodgkin's lymphoma, 10 with acute lymphoblastic leukaemia, eight with acute myeloid leukaemia, five with chronic myeloid leukaemia, four with chronic lymphocytic leukaemia, four with multiple myeloma, three with myelodysplastic syndrome, two with myelofibrosis and one with thalassemia) who developed PCP. Among these, 18 (33%) underwent stem cell transplantation; only two received an oral prophylaxis with trimethroprim/sulphamethoxazole. Twelve patients (22%) developed PCP despite protective isolation in a laminar airflow room. The most frequent symptoms were: fever (86%), dyspnoea (78%), non-productive cough (71%), thoracic pain (14%) and chills (5%); a severe hypoxaemia was present in 39 patients (71%). Chest radiography or computerized tomography showed interstitial infiltrates in 34 patients (62%), alveolar infiltrates in 12 patients (22%), and alveolar-interstitial infiltrates in nine patients (16%). Bronchoalveolar lavage was diagnostic in 47/48 patients, induced sputum in 9/18 patients and lung biopsy in 3/8 patients. The diagnosis was made in two patients at autopsy. All patients except one started a specific treatment (52 patients trimethroprim/sulphamethoxazole, one pentamidine and one dapsone). Sixteen patients (29%) died of PCP within 30 d of diagnosis. Multivariate analysis showed that prolonged steroid treatment (P < 0.006) and a radiological picture of diffuse lung involvement (P < 0.003) were negative diagnostic factors.
