Objective: To investigate whether patient-reported symptoms provide independent prognostic information for survival in patients with hematological malignancies., Study Design and Setting: Overall 119 patients with various diagnoses were recruited in an observational study and symptoms were assessed with the M.D. Anderson Symptom Inventory (MDASI). Key potential socio-demographic, biomedical, and physician-reported prognostic candidates were also considered. The Cox proportional hazards regression model was used for both univariate and multivariate analyses of survival. Additional sensitivity analysis, based on 500 bootstrap-generated simulation datasets, was also performed to confirm the results obtained with the Cox regression model., Results: The median survival of the entire cohort was 4.8 months (range 0-28 months). The MDASI was completed at baseline by 91% of patients. The final multivariate model retained two parameters as independent prognostic factors for survival: clinical prognostic group and patient's self-reported severity of drowsiness. The following hazard ratios (HR) were found for curable vs. terminal: 0.055 (95% CI, 0.022-0.136; P < 0.001) and 0.193 (95% CI, 0.103-0.362: P < 0.001) for advanced vs. terminal. Patient's self-reported severity of drowsiness independently predicted survival with a HR of 1.801 (95% CI, 1.044-3.107; P = 0.033). Additional sensitivity analysis confirmed the independent prognostic value of variables identified in this study., Conclusion: The results suggest that patients' self-reporting of symptoms provides independent prognostic information for survival in patients with hematologic malignancies. These findings underscore the value of collecting patient-reported symptom data in routine clinical practice., (© 2012 John Wiley & Sons A/S.)

Between January 1972 and December 1982 60 patients with pathological stage IA and IIA Hodgkin's disease (HD) were submitted to Mantle irradiation only. Twenty-five were in stage I (32.1%) and 35 in stage II (67.9%). All patients were submitted to staging laparotomy. Cases with large mediastinal mass were excluded from this series. Delivered doses were 44 Gy in involved areas, 40 Gy on the mediastinum and 36 Gy on uninvolved sites. Twenty-four patients in stage I (96%) and 33 in stage II (94.2%) obtained complete remission. Actuarial 10- and 20-yr overall (OS) rates were 86% and 79.1%, respectively. Event-free (EFS) and relapse-free (RFS) survival rates at 10 and 20 yr were 67.5% and 62.1%, respectively. The occurrence of disease relapse resulted in the only statistical significant prognostic factor for OS in both univariate and multivariate analysis. Distant and extranodal recurrences were significantly (P<0.01) related to a reduced OS. On multivariate analysis stage was the only determinant factor for increased RFS. Extended field RT proved to be an effective curative modality for stage I HD patients, whereas 15 out of 33 patients in stage II relapsed requiring salvage therapy. Long-term analysis of survival and treatment-related morbidity rates will improve our knowledge and assist the physicians to choose the therapeutic option to offer to HD patients.

Acute promyelocytic leukaemia (APL) exhibits peculiar epidemiological, clinical, cytogenetic and molecular features, compared to the other acute myeloid leukaemias (AML). Data on epidemiology and occupational risk factors for APL desumed from the GIMEMA archive are reported and compared with those of the other AML. An exploratory case-case study was designed on AML patients from 56 haematology centres in Italy. Overall, 4296 patients older than 15 yr with a new diagnosis of acute leukaemia were recorded between July 1992 and July 1997. Of these, 335 were classified as APL, and 2894 as other AML. The median age of APL patients was 43 compared to 59 yr for the other AML (p < 0.00001). In order to identify peculiar risk factors for APL development, different parameters were compared in the 2 groups. After adjusting by age no significant differences were observed with regard to education, lifetime prevalence of cancer among siblings and previous diseases in the patient's history. Occupational exposure as a possible risk factor for APL showed no increased risk compared to other AML among farmers, builders and leather workers. A significant association was found in electricians (OR=4.4, 95% CI=2.0-9.7) and a weak association was found in wood workers (OR=3.2, 95% CI=0.8-10.8). The proportion of APL with respect to other AML was significantly higher in the north east of Italy compared to the rest of the country (OR=1.7, 95% CI=1.3-2.2). These data confirm the younger age of APL patients compared to the other AML. A possible role of electromagnetic fields is suggested by the higher risk of APL in electrical workers and in the more industrialized areas of the country.

The incidence of thrombotic complications chronologically related to L-asparaginase administration is retrospectively analyzed in 238 adult ALL patients treated according to the GIMEMA protocol ALL 0288. The patients (126 males and 112 females, aged 12-68 years, median 29) received E. coli L-asparaginase (L-ase) in the induction phase at a dosage of 6000 U/m2/day x 7 d starting on d 15, as well as vincristine, prednisone, daunorubicin and cyclophosphamide, the last-named by random 1:1. Ten patients (4.2%) developed thrombotic complications 5-15 d (median 11 d) after the start of L-ase treatment. The thrombotic events, which were lethal in 5 patients, involved the cerebral sinus (5 cases), the cerebral arteria (2 cases), the portal vein (1 case), the pulmonary district (1 case), and a deep vein in the lower extremity (1 case). The occurrence of these complications was not related to the general thrombotic risk factors, nor to the main clinical and laboratory data registered at diagnosis and immediately before the start of L-asparaginase treatment. The present study documents for the first time in a sufficiently large series of adult ALL patients that the incidence and the severity of thrombotic events related to L-ase administration are relevant and need further consideration.

Southern blot analyses were performed in sequential DNA samples from 4 patients with Ph' + chronic myeloid leukaemia (CML) who underwent lymphoid or mixed blast crisis (BC). Genomic rearrangements at the breakpoint cluster region (bcr) and immunoglobulin heavy chain (IgH) gene level provided, in these cases, a sensitive and specific evaluation of response to therapy both in terms of blasts and Ph' + cell suppression. Recurrent BC was molecularly characterized in the 4 patients, showing each time identical individual specific DNA rearrangement patterns. Residual blasts were detected in 2 cases during intervening chronic phases by IgH rearrangements. Such findings highlight the specificity of these molecular markers, clearly indicating the failure of ablative therapy in eradicating the neoplastic clone. Finally, molecular and phenotypic identity in individual recurrent BC also suggested, in our cases, a lack of clonal evolution during disease progression.

Intermediate-dose (25 mg/m2) intravenous melphalan has been evaluated in 34 multiple myeloma patients refractory to standard chemotherapies. The median time from diagnosis to entering of patients into the study was 27 months (range 7-71 months). A response was obtained in 12/34 patients (35%). 4 of 12 responding patients have relapsed and 2 of these have died; 8 responders have not relapsed and are still alive. The median duration of survival after 28 months of follow-up has not yet been reached in the group of patients responding to treatment. However, the overall median duration of survival for the 34 patients entered into the study was 8 months. The median duration of response was 16 months. Toxicity was limited to leukopenia, thrombocytopenia, nausea and vomiting. This lack of severe toxicity allowed us to administer the drug on an outpatient basis. The response rate and the low toxicity observed in this group of patients are encouraging and suggest that intermediate-dose intravenous melphalan is an effective and safe second line treatment for patients with multiple myeloma not responding to conventional treatment.

The feasibility and the antileukemic activity of a double sequential autograft has been evaluated in 3 patients affected by AML in first hematological relapse. Bone marrow collection and cryopreservation was performed twice: during first complete remission (CR) and during second CR. At the time of relapse patients underwent first ABMT with BAVC preparative regimen achieving a second CR without any remarkable complications. After 4, 5 and 4 months respectively a second ABMT was performed with a different preparative regimen, consisting of cyclophosphamide and fractionated total body irradiation (Cy + F-TBI). A delay in platelet recovery was observed after the second procedure as compared to the first, while neutrophils recovery was comparable. 1 patient died in CR (on day +91 after second ABMT) of interstitial pneumonitis. 2 patients are alive and well without evidence of disease after 46 and 53 months of unmaintained second CR. This experience shows the high antileukemic potential of treatment with a double sequential autograft; 2 relapsed patients in fact are long-term survivors with a second CR longer than the first.
