RESUMO

We report herein a multicentre retrospective analysis of 192 consecutive patients with symptomatic refractory/relapsed multiple myeloma (RRMM) treated with daratumumab in combination with bortezomib or lenalidomide as salvage therapy at 9 haematological centres in Puglia. Choice of both regimens was based on previous treatment and/or physicians' preference. Considering the under-representation of older patients (very old patient ≥ 80 years) in clinical trials and the prognostic and predictive importance and value of frailty status, here, we further characterised the patient cohort by age. The overall response rate (ORR) was generally lower than what was previously reported in the CASTOR (ORR 72.6% vs 85%) and POLLUX (ORR 86.5% vs 93%) trials. The lower ORR in our analysis compared to the CASTOR and POLLUX trials could be related to a less selected population. Similarly, amongst very old patients, the ORR was encouraging: ORR to treatment with DVd (daratumumab + bortezomib + dexamethasone) was 66.7%, and ORR to treatment with DRd (daratumumab + lenalidomide + dexamethasone) was 92.3%. Median TTP (time to progression) was 10.8 months (1-year TTP: 44.7%; 2-year TTP: 25.3%) in the DVd group; median TTP was not reached in the DRd group (1-year TTP: 82.7%; 2-year TTP: 71.4%). Median OS (overall survival) was not reached either in the DRd group (1-year OS: 85.9%; 2-year OS: 73.7%) or the DVd group (1-year OS: 70.2%; 2-year OS: 58.9%).

RESUMO

Infections by multidrug-resistant (MDR) bacteria are a worrisome phenomenon in hematological patients. Data on the incidence of MDR colonization and related bloodstream infections (BSIs) in haematological patients are scarce. A multicentric prospective observational study was planned in 18 haematological institutions during a 6-month period. All patients showing MDR rectal colonization as well as occurrence of BSI at admission were recorded. One-hundred forty-four patients with MDR colonization were observed (6.5% of 2226 admissions). Extended spectrum beta-lactamase (ESBL)-producing (ESBL-P) enterobacteria were observed in 64/144 patients, carbapenem-resistant (CR) Gram-negative bacteria in 85/144 and vancomycin-resistant enterococci (VREs) in 9/144. Overall, 37 MDR-colonized patients (25.7%) developed at least one BSI; 23 of them (62.2%, 16% of the whole series) developed BSI by the same pathogen (MDRrel BSI), with a rate of 15.6% (10/64) for ESBL-P enterobacteria, 14.1% (12/85) for CR Gram-negative bacteria and 11.1% (1/9) for VRE. In 20/23 cases, MDRrel BSI occurred during neutropenia. After a median follow-up of 80 days, 18 patients died (12.5%). The 3-month overall survival was significantly lower for patients colonized with CR Gram-negative bacteria (83.6%) and VRE (77.8%) in comparison with those colonized with ESBL-P enterobacteria (96.8%). CR-rel BSI and the presence of a urinary catheter were independent predictors of mortality. MDR rectal colonization occurs in 6.5% of haematological inpatients and predicts a 16% probability of MDRrel BSI, particularly during neutropenia, as well as a higher probability of unfavourable outcomes in CR-rel BSIs. Tailored empiric antibiotic treatment should be decided on the basis of colonization.

RESUMO

PURPOSE: The main objective of this study is to gain a deeper understanding of how patients suffering from chronic myeloid leukemia (CML) cope with their illness. The study aims to reconstruct the subjective meaning-making process related to CML in order to gain insights into the impact the disease has on patients' emotions and everyday lives, as well as to explore the psychological impact of their being presented with the chance to suspend their therapy and recover from the disease. METHODS: Data were gathered from a qualitative study conducted in Italy on 158 Italian CML patients. Basing the study on the narrative inquiry approach, the patients were required to describe their patient journey in a qualitative narrative diary. These contained prompts to elicit the free expression of their needs, expectations, and priorities. A lexicographic analysis was carried out with T-LAB software and in particular a thematic analysis of elementary contexts (TAECs) and a word association analysis (WAA). RESULTS: The TAEC detected four thematic clusters related to two factors (temporal frame and contextual setting) that explained the variance among the narratives. The WAA evidenced a wide variety of emotions, both positive and negative, as patients reacted to the possibility of interrupting their therapy. CONCLUSIONS: A better understanding of patients' experiences can offer insights into promoting the development of more sustainable healthcare services and into therapeutic innovation aimed at improving patients' quality of life and at engaging them more in their treatment. The findings of this study can also help make medical professionals more aware of the patient's burden and help them identify potential interactions and emotional levers to improve clinical relationships.

RESUMO

BACKGROUND: The best therapeutic approach for primary plasma cell leukemia (PPCL) remains unknown so far. In very limited studies, the poor clinical outcome of this aggressive variant of multiple myeloma seemed to be ameliorated by the use of the proteasome inhibitor bortezomib. Aiming to provide more consolidated data, this multicenter retrospective survey focused on unselected and previously untreated PPCL patients who had received bortezomib as frontline therapy. PATIENTS AND METHODS: Twenty-nine patients with PPCL were collected. Bortezomib was given at standard doses and schedules, in various combinations with dexamethasone, thalidomide, doxorubicin, melphalan, prednisone, vincristine, and cyclophosphamide. RESULTS: An overall response rate of 79% was observed, with 38% of at least very good partial remission. Grade 3-4 hematological, neurological, infectious, and renal toxic effects occurred in 20%, 21%, 16%, and 4% of patients, respectively. After a median follow-up of 24 months, 16 patients were alive (55%), 12 of whom were in remission phase and 4 relapsed. The best long-term results were achieved in patients who received stem-cell transplantation after bortezomib induction. CONCLUSION: Bortezomib, used as initial therapy, is able to increase the percentage and the quality of responses in PPCL patients, producing a significant improvement of survival.

RESUMO

We conducted a phase I-II study to evaluate Nilotinib (NIL) safety and pharmacokinetics in 22 SR-cGVHD patients; we also evaluated ORR by using in parallel NIH criteria and an exploratory approach, combining objective improvement (OI) without failure criteria (GITMO criteria). Results: 22 patients were enrolled. After dose escalation up to 600 mg/day, MTD was not reached. Main toxicities were asthenia, headache, nausea, pruritus, cramps, and mild anemia. Mean and median plasma concentrations of NIL (C-NIL) were 817 (SD ± 450) and 773 ng/ml. ORR at 6 months, according to 2005 and 2014 NIH and GITMO criteria were 27.8%, 22.2%, and 55.6% respectively; close correspondence has been observed for ORR, according to 2014 NIH criteria, both assessed in a conventional way and assisted by dedicated software (CROSY). At 48 months OS was 75% while FFS, according to NIH and GITMO criteria, was 30 and 25%. In conclusion the safety profile of NIL and long-term outcome makes NIL an attractive option in SR-cGVHD. Exploratory GITMO criteria could represent an alternative tool for easy response evaluation in patients with prevalent skin and lung involvement, but require validation in a larger population; CROSY software showed excellent reliability in capturing ORR according to the 2014 NIH criteria.

RESUMO

BACKGROUND: The aim of the study was to verify the efficacy and safety of the addition of celecoxib to FOLFIRI combination therapy in patients affected by advanced colorectal cancer. PATIENTS AND METHODS: Eighty-one chemotherapy-naïve patients entered in this randomized phase II trial of the GOIM (protocol no. 2301). Patients were randomized to receive FOLFIRI regimen (arm A): irinotecan 180 mg/m(2) on day 1 with LV5FU2 regimen (LV at 100 mg/m(2) administered as a 2-h infusion before FU at 400 mg/m(2) as an intravenous bolus injection, and FU at 600 mg/m(2) as a 22-h infusion immediately after 5-FU bolus injection on day 1 and 2); or FOLFIRI plus celecoxib 400 mg twice daily for 14 days (arm B). Both treatments were repeated every 2 weeks. RESULTS: Seventy-seven patients (38 in arm A and 39 in arm B) were evaluable for response. The overall response rate was 41% in arm A (95% CI 27% to 57%) and 35% in arm B (95% CI 20% to 50%). When only assessable patients were analyzed, overall response rate was 45% in arm A (95% CI 29% to 61%) and 36% in arm B (95% CI 21% to 51%). Median time to progression, median duration of response and survival were, respectively, 8 months, 9 months and 16 months in arm A, and 7 months, 9 months and 19 months in arm B. All patients were evaluable for toxicity, which was globally mild in both arms; grade 3-4 toxicity was uncommon, and gastrointestinal disturbances were the most common. CONCLUSIONS: FOLFIRI regimen is effective and well-tolerated as a first-line treatment in patients with advanced colorectal cancer. The addition of celecoxib to FOLFIRI regimen does not improve results.

RESUMO

PURPOSE: To ascertain whether vinblastine, bleomycin, and methotrexate (VBM) (CT) combined with extended-field radiotherapy (EF RT) is effective enough to spare laparotomy in early, favorably presenting Hodgkin's disease (HD) patients. PATIENTS AND METHODS: Fifty patients with clinical stage IA or IIA HD with favorable histology and no bulky masses entered a prospective multicenter study started in January 1988. The median follow-up time was 38 months. RESULTS: All patients achieved a complete remission (CR). Five relapsed after 3 to 40 months and underwent successful salvage therapy. The actuarial remission rate was 0.89% at 3 years and 0.82% at 5 years. Two patients died in CR: one of severe pulmonary toxicity, the other of a second neoplasia (adenocarcinoma of the lung), 2 and 43 months after the end of therapy, respectively. The hematologic toxicity recorded during VBM CT was mild on the whole. Major toxicity was represented by pulmonary side effects and neurologic symptoms. Multiple regression analysis demonstrated that pulmonary toxicity was significantly related only to the amount of RT delivered to the mediastinum and not to the relative dose of bleomycin, to the dose-intensities of the three drugs in the regimen, or to patient age or sex. The same statistical technique showed that the only clinical factor related to grade of neurotoxicity was vinblastine dosage. CONCLUSION: VBM CT combined with EF RT is an effective treatment for early, clinically staged, favorable HD patients. However, the toxicity of this combination suggests that certain modifications should be evaluated.

RESUMO

PURPOSE: We explored the feasibility, toxicity, and preliminary results of a chemotherapy (CT) regimen, mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)/epidoxirubicin, bleomycin, and vinblastine (EBV)/lomustine (CCNU), doxorubicin, and vindesine (CAD), derived through hybridization, shortening, and intensification of a corresponding 10-drug alternating combination CAD/MOPP/doxorubicin, bleomycin, and vinblastine (ABV), effective in treatment of advanced Hodgkin's disease (HD). PATIENTS AND METHODS: Hybridization involved all drugs except CCNU and mechlorethamine, which were administered in alternating cycles; the length of therapy was reduced from nine to six cycles. The average projected drug doses during the six cycles were increased by 42%, with an overall 1.54 dose-intensification; epidoxorubicin was substituted for doxorubicin at equivalent tumoricidal doses. Radiotherapy (RT) was optional and its indications were limited. RESULTS: Eighty assessable patients with previously untreated, advanced or unfavorably presenting HD were treated in nine cooperating institutions between 1988 and 1991. RT was delivered to 22 patients. Remissions were complete (CR) in 75 patients (93%), partial in three (4%), and null in two (3%). The median relative dose-intensity was 0.71 for the overall regimen. Three of five patients who failed to achieve CR, and two of the four who relapsed, received lower relative dose-intensive cycles. Nonhematologic toxicity was acceptable, but there was considerable hematologic toxicity. Fatal gastrointestinal bleeding was seen in one patient. CONCLUSION: Caution is advised due to the short median follow-up period. Nevertheless, in addition to the excellent response rate, (1) the results were reached through abbreviation, intensification, and hybridization of an existing alternating regimen; (2) RT had limited use in this program, which may have contributed to lowering the risk of second tumors; and (3) the results were obtained in a multicenter study (a condition that often impairs results from clinical trials).

RESUMO

This current retrospective multicenter analysis represents, to our knowledge, the first Italian study evaluating the efficacy and toxicity profile of "lenalidomide plus dexamethasone" as salvage therapy in patients with recurrent-refractory MM in the real life contest. Our study included patients who are usually excluded from clinical trials because of unfavorable baseline characteristics. Median OS was significantly longer in patients receiving "lenalidomide plus dexamethasone" for more than 12 months compared with those who had received "lenalidomide plus dexamethasone" for a shorter interval (P<0.0001). Median OS was not affected by best response achieved (P 0.4) and age (P 0.3). Quality of response did not correlate with number of previous lines of therapy (P 0.77) and age. Higher ORRs were recorded in the patients group with relapsed MM compared to those with refractory disease, but this difference was not statistically significant (P 0.38).

RESUMO

Data from eight randomised trials on high-dose chemotherapy (HDC) for metastatic breast cancer (MBC) have been published, but only seven studies are evaluable after the Bezwoda trial was discredited. Moreover, overall survival (OS) has been evaluated in only four out of seven studies since three had a crossover design. OS was similar for the HDC and standard-dose chemotherapy (SDC) group in the four evaluable trials, while disease-free survival (DFS) was improved in the HDC group in six of the seven trials. The delay in relapse for patients with metastatic disease represents an important clinical outcome; furthermore, since none of the reported studies randomised more than 220 patients, their statistical power may have been too limited to detect meaningful survival differences. Finally, preliminary experiences have shown that HDC seems to be the ideal platform upon which to build novel therapies. In conclusion, HDC remains an important field of clinical research for breast cancer patients with stage IV disease and, from the studies reported in this article, there is some evidence for offering this therapeutic modality to selected patients who are interested in a medically aggressive approach.

RESUMO

Seventy-two patients with non-Hodgkin's lymphoma were evaluated for the presence of molecular markers (IgH, bcl-1, bcl-2 rearrangement) on bone marrow, at diagnosis and after PBSCT, and on harvests in order to find a possible predictive role of minimal residual disease on treatment outcome. At diagnosis, 41 (59%) out of 69 available bone marrows showed molecular involvement. Fifty-six percent of leukaphereses were involved, mainly indolent lymphoma (P = 0.001) or advanced disease (P = 0.01). Ex vivo purging cleared only one stem collection out of 31 PCR-positive leukaphereses. Aggressive lymphomas showed both a longer overall survival (OS) (P = 0.03) and relapse-free survival RFS (P = 0.02) when transplanted with unpurged stem cells, whereas indolent NHL survival was not influenced by ex vivo purging. Twenty out of 26 samples taken during follow-up had bone marrow involvement at diagnosis. Of these, 15 cleared their bone marrow; both OS and RFS were significantly longer in the PCR-negative cases (P = 0.05 and P = 0.005). At 1 year after PBSCT, 75% of patients were PCR negative, with 50% molecular remissions; the relapse rate was 55% for patients still PCR positive vs 29% for those who were PCR negative. Thus, after high-dose chemotherapy, close molecular monitoring of MRD using qualitative PCR techniques seems to represent a reliable prognostic indicator.

RESUMO

CD38 identifies a surface molecule with multi-functional activity. Its prognostic importance in B-cell chronic lymphocytic leukemia (B-CLL) is currently under investigation in view of the fact that two different groups have recently indicated that CD38 expression could be an independent prognostic marker in B-CLL. We analyzed the clinico-biological features of 61 immunologically typical (CD5+CD23+) B-CLL patients stratified according to the CD38 expression. Twenty-two (36%) patients expressed CD38 in more than 30% of CD19-positive cells and were considered as CD38-positive B-CLL. Atypical morphology (p 0.02), peripheral blood lymphocytosis (p 0.01) and diffuse histopathologic bone marrow pattern (p 0.003) were findings found to be closely associated with CD38 expression. On the other hand, A and B Binet stages (p 0.02) and interstitial bone marrow involvement (p 0.005) were more represented in the CD38-negative B-CLL group. Trisomy 12 was detected more frequently in the CD38-positive B-CLL group, while 13q14 deletions mainly occurred in CD38-negative group (p 0.005). Finally, median survival of CD38-positive B-CLL patients was 90 months, while it was not reached at 180 months in CD38-negative patients. Taken together, our data strongly suggest that the evaluation of CD38 expression may identify two groups patients with B-CLL greatly differing in their clinico-biological features.

RESUMO

The purpose of this study was to test the efficacy and safety of thymostimulin (TS) administered in addition to conventional chemotherapy in patients with intermediate- and high-grade non-Hodgkin's lymphoma (IG, HG-NHL). A total of 150 patients with newly diagnosed IG- or HG-NHL were entered in a multicenter trial to compare the effectiveness of two different third-generation regimens (MACOP-B versus ProMACE-CytaBOM) and were randomized to receive chemotherapy (CT) alone or CT + TS. In both regimens doxorubicin was replaced by a 20% higher dose of epidoxorubicin. TS was administered i.m. at a dose of 1 mg/kg daily on days 22-28 of each drug course to patients treated with ProMACE-CytaBOM, and on days 22-29, 50-57, and 77-85 to patients treated with MACOP-B. There were 134 fully evaluable patients: 68 treated with CT alone and 66 treated with CT + TS. Patients treated with CT + TS had a higher complete remission (CR) rate compared to patients given CT alone (59.1% vs 42.4%; P = .05). CR were significantly higher for patients treated with CT + TS in the groups with IG-NHL (P = .01), in those aged less than 60 years (P = .05), with good performance status (P = .05), and normal hemoglobin levels (P = .05). Four-year survival rates are 64.5% for patients treated with CT + TS and 43.0% for those treated with CT alone (P = .30). No difference between the two treatment arms have been observed as regards drug-related toxicity and the number and severity of infectious episodes. The use of TS during the 7 days before chemotherapy has been associated with a significantly superior CR rate. The advantage of CT + TS was mostly obtained in patients with IG-NHL, and those with good performance status or normal hemoglobin levels. In these patients TS may have potentiated the host reactions against the tumor, leading to an increase in NK activity and the production of cytokines. This postulated increase in the effectiveness of chemotherapy after TS might also explain the absence of the expected myeloprotective action.

RESUMO

P-glycoprotein (P-170) is the phenotypic marker of tumoral cells that show the phenomenon of multidrug resistance (MDR). Using an immunocytochemical approach, we employed the monoclonal antibody C219 (which recognizes an epitope of such a glycoprotein) to evaluate in cytologic samples the expression of P-170 on neoplastic cells from 52 patients affected by different hematologic malignancies and its eventual correlation to clinical outcome. Longitudinal studies were also performed in 14 patients. Results obtained demonstrated that a) the so-called "MDR phenotype" may be heterogeneously represented (from less than 1 to 100% of positive cells) in hemopoietic tumors at diagnosis (without exposure to pharmacologic agents), as well as during the course of the disease, although a more substantial presence of P-170 occurred in treated patients. There was no correlation between neoplastic kinetic activity (such as expression of Ki 67 recognized nuclear proliferation-associated antigen) and P-170-positive cells. b) Percentage of positive cells as well as intensity of staining seemed to be important in determining MDR; in general, there was a strong correlation between expression of P-170 in more than 20% of neoplastic cells and a lack of response to chemotherapy. However, some false-positive and false-negative cases were observed. c) The detection of scattered P-170-positive cells may predict a pharmacologic selection of intrinsic or mutant-resistant clones.

RESUMO

A simple but efficient algorithm has been developed for computer analysis of eye tracking movements. The program separates smooth pursuit and saccadic eye movements. Separation of the two components is achieved using a two-step process of saccade detection. First, an AR model of the velocity of the smooth component is identified and used to determine a Kalman filter. Secondly the innovation sequence generated by this filter allows saccade detection. The precise beginning and end of each saccade are found using a Hinkley algorithm. Examples are given of analysis procedure for eye tracking of a random moving target. The method proved to be highly reliable and could be easily extended to other eye movements such as nystagmus.

RESUMO

The effects of high frequency hand vibration (150 Hz) on simultaneous ocular and manual tracking performances were investigated in trained human subjects. First, a zero-order pursuit tracking task was performed with and without direct visual control of the hand. Second, eye tracking of an imaginary target linked to the hand was also performed. The results show that hand vibration significantly alters eye and hand tracking performances when the hand is out of sight. However, when the hand is placed in the visual field, tracking performances are less affected by vibration. Visual cues on limb segments may compensate to some extent for the vibration-induced alteration of proprioceptive information otherwise used to control movements. Eye movements are altered during vibration while the subject is tracking or fixating an imaginary target attached to the hand. These findings explicitly show that hand vibration can perturb oculo-manual coordination control. The present results imply that vibration-induced activity of somesthetic mechanoreceptors is likely to contribute to oculomanual coordination alteration and tracking decrement in vibratory environments. Furthermore, direct visual control of the hand and/or arm may be of particular interest in manipulation tasks executed under vibration.

RESUMO

The bilateral primary renal lymphoma (PRL) is a rare disease with a high mortality rate (75% within the first year). We report the case of a fifty-three years old women observed in January 2011 for renal colic. Ultrasonography showed hypoechoic lobular formations in the kidney. Blood tests showed: creatinine 1.8 mg/dl, urea 75 mg/dl , Creatinine Clerance 35 ml/m, hemoglobinemia 11 g/dl, with blood cells 8.500/mcL, Albumin 2.8 g/dl, Beta -2 micro - 27.3/mL. Proteinuria was 0.3 g/24 hours. The CT scan showed kidneys with larger dimensions and multiple hypodense areas infiltrating the renal parenchyma with contrast-enhanced low in which kidneys had lesions similar to "leopard skin". The CT scan showed no enlarged lymph nodes. Renal biopsy showed: renal parenchyma largely occupied by infiltration of lymphoid elements, small and medium-sized, densely packed with compression of the tubular structures . Immunofluorescence for immunoglobulin (Ig) G, IgA, IgM, C3, C4, C1q, fibrinogen, kappa and lambda were negative. The bone marrow biopsy excluded lymphomatous infiltration. The histological diagnosis was "non-Hodgkin's B-cell lymphoma"; the clinical diagnosis was LRBP. The patient was treated by 6 cycles of R-CHOP-21 protocol (rituximab - endoxan, adriblastina , vincristine, prendnisone), the latter of which practiced in August 2011. The pt is currently in follow-up hematology and nephrology . The first TAC control , in October 2011, showed a complete regression of the lesions infiltrating . This finding was confirmed by two other CT scan performed in February and October 2012. The last blood tests of February 2013 showed : creatinine 1.1 mg / dl , Urea 40 mg/dl, proteinuria absent. Currently, the pt is asymptomatic and is being treated by low dose of ACE inhibitor. The bilateral PRL is considered a severe disease with one-year mortality of 75% . The successful outcome of the case described can be attributed to haematological therapy and to the early diagnosis.
