Haemato-oncology and burnout: an Italian survey.

This cross-sectional survey aimed to evaluate the prevalence of burnout and estimated psychiatric disorders among haemato-oncology healthcare professionals in Italy. The aspects of work that respondents perceive as stressful and satisfying have also been examined. The assessments were made using the Maslach Burnout Inventory (MBI), General Health Questionnaire and a study-specific questionnaire. Logistic regression models were applied to show associations between different sources of work-related stress and burnout. Three hundred and eighty-seven out of 440 (87.95%) returned their questionnaires. The scores on MBI subscales indicate a high level of emotional exhaustion in 32.2% of the physicians and 31.9% of the nurses; a high level of Depersonalisation in 29.8 and 23.6%, respectively; and a low level of personal accomplishment in 12.4 and 15.3% respectively. The estimated prevalence of psychiatric disorders was 36.4% in physicians and 28.8% in nurses. Statistical analysis confirmed age, sex, personal dissatisfaction, physical tiredness and working with demanding patients to be associated with burnout. In conclusion, haemato-oncology healthcare professionals report a level of burnout and estimated psychiatric morbidity comparable to other oncological areas. Knowledge of the mechanisms of burnout and preventing and dealing with them is therefore a fundamental requirement for the improvement of quality in health services and job satisfaction.

Cytomegalovirus infection after autologous stem cell transplantation: incidence and outcome in a group of patients undergoing a surveillance program.

This study was performed to evaluate the incidence, risk factors, and outcome of cytomegalovirus (CMV) infection in autologous stem cell transplantation (ASCT), with the aim of performing preemptive therapy in patients with antigenemia. Starting from 2001, 171 consecutive ASCTs were performed in 136 patients; 102 of these patients were seropositive for CMV at the onset of hematological disease. In all these patients, a CMV pp65 antigenemia assay was determined weekly, starting from the day when the absolute neutrophil count went above 500/microL, and until day 60 after ASCT; subsequently, antigenemia was determined only when a CMV infection was suspected. Among the 136 transplanted patients, 40 (29.4%) presented a positive antigenemia; all of them were seropositive for CMV before ASCT; and no cases of primary infection were seen. The incidence of CMV infection in the seropositive population was 40/102 (39.3%); 6 patients (5 with multiple myeloma and 1 with non-Hodgkin's lymphoma) who received 2 ASCTs developed CMV infections after both transplantations, so that positive antigenemia developed after 46/171 (26.9%) transplantations. First positive antigenemia presented a median of 32 days (range 7-57) after stem cell reinfusion. The median antigenemia level at the first appearance was 2/200,000 (range 1-1000). No significant prognostic factors could be shown. Enteritis was present in 5 patients; 2 of them also had fever, and 1 of them also had thrombocytopenia. In 5 patients fever without any other clinical signs or symptoms was present; 30 patients were asymptomatic. Fourteen patients were treated with anti-CMV drugs. CMV reactivation was successfully treated in all patients, and no patient died from CMV disease.

Two novel mutations and a new STK11/LKB1 gene isoform in Peutz-Jeghers patients.

Peutz-Jeghers syndrome (PJS) is a rare autosomal dominantly inherited disorder with variable expression and incomplete penetrance characterized by mucocutaneous pigmentation, predisposition to hamartomatous intestinal polyposis, and various other neoplasms. It occurs in approximately 1 in 8,300 to 29,000 live births. In nearly 50% of patients PJS is caused by germ line mutations in the STK11/LKB1 serine/threonine kinase gene, the only kinase gene currently known to act as a tumor suppressor. We have performed a mutation search in the STK11/LKB1 gene in 8 sporadic cases and 3 PJS families using a combination of different screening techniques. We have identified four mutations, two of which I177N and the IVS2+1A->G, were previously unreported. We have also evaluated the presence of cDNA alterations by means of RT-PCR analysis and direct cDNA sequencing and have found two aberrant transcripts in a single PJS case despite the lack of any apparent genomic alteration. Finally, we report the presence of a novel STK11/LKB1 cDNA isoform observed in all the normal subjects studied as well as in the majority of the PJS patients.

P-Glycoprotein Expression in Acute Myeloid Leukaemia Cells at Diagnosis: Its relationship to Daunorubicin or Idarubicin Induction Therapy and Survival; Malignancy.

We investigated the expression of P-glycoprotein (P-gp) in 50 adults with de novo diagnosed acute myeloid leukaemia (AML) and the relationship between presence of P-gp in leukaemic cells and efficacy, as remission induction and survival rate, of two different anthracyclines, daunorubicin (DNR) and idarubicin (IDR). We found that 30 out of 50 patients (60%) were negative (Group 1) and 20 (40%) were positive (Group 2) for P-gp expression evaluated by mean of MRK16 MoAb using a cut-off of 10% positive cells. Thirty-five out of 50 patients (70%) obtained complete remission (CR); depending on P-gp expression, the CR rate was 80% for group 1 and 45% for group 2 (p < 0.005). The median duration of overall survival was 20 months for patients in Group 1 as compared with 10 months for patients of Group 2 (p < 0.005). Regarding the anthracycline used, no significant difference in CR was observed in patients of Group 1 (75% of CR with DNR vs. 90% with IDR); Group 2 obtained 40% of CR with DNR vs. 70% with IDR (p < 0.005). The median duration of overall survival (OS) with the two regimens was comparable in Group 1, while it was significantly longer in patients of Group 2 treated with IDR compared with DNR regimen (p < 0.005). These results confirm the prognostic value of P-gp expression in AML at first appearance and we suggest that idarubicin could be a valid anthracycline drug in the treatment of AML to be evaluated as potential drug of choice in patients with primary or drug-induced multidrug resistance.

Idarubicin in combination with cytarabine and VP-16 in the treatment of post myelodysplastic syndrome acute myeloblastic leukemia (MDS-AML).

Fifteen patients with a primary myelodysplastic syndrome (MDS) transformed into acute myeloblastic leukemia (AML) were treated with an intensive chemotherapy regimen containing idarubicin. A complete response (CR) was obtained in 10 patients (66.6%). In five of them this was achieved after a single course of chemotherapy. The median time to achieve a CR was 32 days (range 16-42). A partial remission (PR) was obtained in 2 patients after two induction courses of chemotherapy. One patient died during the first induction course following acute respiratory distress syndrome (ARDS) complication, whereas the chemotherapy regimen failed in 2 patients. A short interval between MDS and transformation into AML was associated with a better chance of achieving a CR. Age, karyotype, type of MDS, peripheral blood or bone marrow findings appeared to have no influence on the response to treatment. The median event free survival for patients who achieved CR was 15 months and the median actuarial survival 18 months. These preliminary results need to be confirmed in a multicentre prospective study comparing idarubicin with other anthracyclines.

Alpha interferon as initial treatment of essential thrombocythemia. Analysis after two years of follow-up.

AIMS AND BACKGROUND: Recombinant alpha-interferon has been shown to be effective in essential thrombocythemia and in thrombocytosis associated with other myeloproliferative disorders. PATIENTS AND METHODS: Twenty-five untreated patients were enrolled in our study from May 1989 to April 1992. Recombinant alpha interferon-2b was administered at an initial dose of 2 megaunits (MU)/m2 three times a week at escalating doses to 5 MU/m2 or the maximum tolerated dose. The mean follow-up for patients still in treatment at the time of this report was 35.9 months (range, 24-63). RESULTS: Fourteen patients (56%) had achieved a complete remission by a mean time of 152 days; 6 patients (24%) had achieved a good partial remission by a mean of 180 days. In addition to the favorable effect on platelet count, a marked improvement in clinical symptoms was observed. Treatment had to be discontinued in 9 patients (36%), 5 for toxicity (3 neurologic, 1 anemia and 1 severe hypertriglyceridemia) at a median of 155 days from the beginning of therapy (range, 30-400). Four patients refused to continue therapy because of low tolerance (flu-like syndrome) at mean of 160 days from the beginning of therapy (range, 34-301). CONCLUSIONS: In our study, lower doses were administered compared with previous short-time trials. The present data show that interferon is an effective alternative to cytostatic agents in long-term treatment of patients with essential thrombocythemia, even when used at lower dosages.

Role of granulocyte colony-stimulating factor in relapsed/resistant intermediate and high-grade non-Hodgkin's lymphoma patients treated with the E-SHAP regimen.

AIMS AND BACKGROUND: The study assessed the role and potential benefit of rhG-CSF in reducing the frequency, duration and severity of neutropenia following cytotoxic chemotherapy according to the E-SHAP protocol and, at the same time in improving the response rate. METHODS: Twenty patients with resistant/relapsed intermediate or high-grade non-Hodgkin's lymphoma were treated with the E-SHAP regimen (etoposide+methyl prednisolone+high dose cytosine arabinoside and cisplatin), and in 15 of them, we administered rhG-CSF between chemotherapeutic courses. RESULTS: The 15 patients who received G-CSF after E-SHAP were neutropenic for a short time and experienced no febrile episodes or infective complications. In contrast, in the group (5 patients) who did not receive G-CSF, the WBC nadir was lower and the number of days with a neutrophil count below 1.0 x 10(9)/L was longer, with a greater risk of inferctious complications. Of the 15 patients, only one had a delay in chemotherapy administration, and the RDI was 95% in the 65% of patients who received G-CSF. Of 5 patients treated with chemotherapy alone, 4 had a delay and the RDI was over 95% in only one patient. We obtained a good overall response rate (70%) in the group who received G-CSF. In the historical group of 5 non-Hodgkin lymphoma patients, we observed only 1 partial response and 4 had progression of disease. CONCLUSIONS: Administration of G-CSF is associated with an acceleration of neutrophil recovery, indicating its potential to reduce the risk of infection. The use of G-CSF permitted us to administer intensive chemotherapy without delay and according to standard dosage, with an improved response rate.
