Background Diffusion‐weighted whole‐body MRI (DW‐MRI) is increasingly used in the management of multiple myeloma (MM) patients, but data regarding the prognostic role of DW‐MRI imaging response after treatment are lacking. The Myeloma Response Assessment and Diagnosis System (MY‐RADS) imaging recommendations recently proposed the criteria for response assessment category (RAC) with a 5‐point scale in order to standardize response assessment after therapy, but this score still needs to be validated. Methods We investigated the prognostic role of RAC criteria in 64 newly diagnosed MM patients after autologous stem cell transplantation (ASCT), and we combined the results of MY‐RADS with those of minimal residual disease (MRD) assessment by multiparametric flow cytometry (MFC). Results Superior post‐ASCT PFS and OS were observed in patients with complete imaging response (RAC1), with respect to patients with imaging residual disease (RAC≥2): median PFS not reached (NR) versus 26.5 months, p = 0.0047, HR 0.28 (95% CI: 0.12–0.68); 3‐year post‐ASCT OS 92% versus 69% for RAC1 versus RAC ≥2, respectively, p = 0.047, HR 0.24 (95% CI: 0.06–0.99). Combining MRD and imaging improved prediction of outcome, with double‐negative and double‐positive features defining groups with excellent and dismal PFS, respectively (PFS NR vs. 10.6 months); p = 0.001, HR 0.07 (95%CI: 0.01–0.36). Conclusion The present study supports the applicability of MY‐RADS recommendations after ASCT; RAC criteria were able to independently stratify patients and to better predict their prognosis and the combined use of DW‐MRI with MFC allowed a more precise evaluation of MRD., The present study supports both the applicability and the clinical usefulness of the proposed Myeloma Response Assessment and Diagnosis System (MY‐RADS) recommendations applied to DW‐MRI imaging obtained after first‐line treatment of MM including ASCT. MY‐RADS RAC criteria were able to independently stratify patients and to better predict their outcome and their prognosis. DW‐MRI proved to be a powerful tool for the assessment of residual bone disease by functional imaging: it complemented bone marrow flow cytometry and may, therefore, represent a step forward in the clinical management of the increasing number of MM patients achieving CR with the novel treatment approaches.

Background Stopping tyrosine kinase inhibitor (TKI) treatment has become a realistic and safe objective for patients who have chronic myeloid leukemia (CML). Both a sustained deep molecular response (sDMR) and the lack of a molecular recurrence after TKI discontinuation are required to reach a durable treatment-free remission (TFR). Methods The potential predictive role of BCR-ABL transcripts in attaining an sDMR and a TFR was analyzed in a strictly consecutive, unselected series of 194 patients who were diagnosed and treated with TKIs at the authors' center. Results Of 173 fully evaluable patients, 67 (38.7%) had the e13a2 transcript, and 106 (61.3%) had the e14a2 transcript. Complete cytogenetic and major molecular remissions were not affected, whereas the achievement of both a DMR (P = .008) and an sDMR (P = .004) was favored significantly in patients who had the e14a2 transcript. After a median of 68 months, the sDMR rate was 39.6% in those with the e14a2 transcript and 19.4% in those with the e13a2 transcript. In addition to transcript type, both the early achievement of a molecular response and starting treatment with a second-generation TKI positively affected the attainment of an sDMR in multivariate analysis. The use of a second-generation TKI as frontline treatment increased the sDMR rate in both transcript types. However, in patients who had the e13a2 transcript, the probability of attaining an sDMR was 37% after 60 months and did not increase further despite continuing therapy. Among 51 of 60 patients who attained an sDMR after discontinuing TKIs, 24 experienced a molecular relapse, but all regained molecular remission after resuming TKI treatment. Again, transcript type influenced TFR maintenance (P = .005), because only 2 patients (3%) with the e13a2 transcript enjoyed a durable TFR compared with 25 (23.5%) of those with the e14a2 transcript. Conclusions The e13a2 transcript hinders the achievement of deep responses and the possibility of stopping TKI treatment in patients with CML.

Autologous stem cell transplantation (ASCT) is feasible and effective in selected older patients with Multiple Myeloma, but specific criteria for evaluating ASCT eligibility in elderly patients are lacking. We evaluated 131 patients aged 65-75 considered for ASCT at our center: The Charlson Comorbidity Index (CCI), Hematopoietic cell transplantation comorbidity index (HCT-CI) and IMWG frailty score were obtained at diagnosis, but the intensity of treatment was left to physician's choice. The scores and age's impact on outcome was analyzed: 85 patients were judged transplant eligible, whereas 46 patients received a less intensive treatment (median follow up 27 months). No patients classified as frail had been considered eligible to ASCT with a worse outcome compared to fit and unfit patients (median PFS (progression free survival): 7.9 vs 32.9 and 29.6 months; P < .001). PFS was superior in the ASCT group (35.6 vs 19.9 months, P .013). In the ASCT group, PFS was better in patients aged 65-69 years than in patients ≥70 (51.5 vs 27.7 months, P.004). Indeed, in unfit patients aged ≥70 the PFS of the ASCT group was comparable to NO ASCT group (18 vs 27 months, P = .33) whereas in unfit patients aged 65-69 PFS was superior in the ASCT group: 43.3 vs 18.4 months, P .01. ISS III and impaired functional status independently affected PFS in a multivariate analysis (P .011 and P .006). While CCI and HCT-CI did not predict different outcome in ASCT patients, the IMWG frailty score would be of help in identifying unfit patients aged 70-75, whose outcome with ASCT selected by clinical judgment was no better than with less intensive treatments.

The purpose of this phase 2, multicenter study was to determine the activity and safety of nonpegylated liposomal doxorubicin as part of "R-COMP" combination in patients with diffuse large B-cell lymphoma and coexisting cardiac disorders. The study was conducted using a Bayesian continuing assessment method using complete remission rate and rate of cardiac events as study endpoints. Between November 2009 and October 2011, 50 evaluable patients were enrolled (median age, 76 years). Median baseline left ventricular ejection fraction (LVEF) was 60%. Ischemic cardiopathy was the most frequent preexisting cardiac disorder (35%), followed by atrial fibrillation (15%), left ventricular hypertrophy (13%), and baseline LVEF

Circulating tumour cells (CTC) are identified exploiting their protein/gene expression patterns or distinct size compared to blood cells. Data on CTC in bladder cancer (BC) are still scarce. We comparatively analyzed CTC enrichment by AdnaTest ProstateCancerSelect (AT) and ScreenCell®Cyto (SC) kits, combined with identification by EPCAM, MUC1, and ERBB2 expression and by cytological criteria, respectively, in 19 nonmetastatic (M0) and 47 metastatic (M+) BC patients, at baseline (T0) and during treatment (T1). At T0, CTC positivity rates by AT were higher in M+ compared to M0 cases (57.4% versus 25%, p = 0.041). EPCAM was detected in 75% of CTC-positive samples by AT, showing increasing expression levels from T0 to T1 (median (interquartile range, IQR): 0.18 (0.07–0.42) versus 0.84 (0.33–1.84), p=0.005) in M+ cases. Overall, CTC positivity by SC was around 80% regardless of clinical setting and time point of analysis, except for a lower occurrence at T1 in M0 cases. At T0, circulating tumour microemboli were more frequently (25% versus 8%) detected and more numerous in M+ compared to M0 patients. The approach used for CTC detection impacts the outcome of CTC studies. Further investigations are required to clarify the clinical validity of AT and SC in specific BC clinical contexts.

[Background] To report on long-term results of a phase 3 trial comparing three versus five cycles of adjuvant chemotherapy (CT) with full-dose epirubicin+ifosfamide in high-risk soft tissue sarcomas (STS)., [Methods] Patients (pts) were randomized to receive three preoperative cycles of epirubicin 120 mg/m2 and ifosfamide 9 g/m2 (Arm A) or to receive the same three preoperative cycles plus two postoperative cycles (Arm B). Radiotherapy could be either delivered in the preoperative or in the postoperative setting. Non-inferiority of the primary end point, OS, was assessed by the confidence interval of the hazard ratio (HR; Arm A/Arm B) derived from Cox model., [Results] Between January 2002 and April 2007, 164 pts were assigned to arm A and 164 to arm B. At a median follow-up (FU) of 117 months (IQ range 103–135 months), 123 deaths were recorded: 58 in Arm A and 65 in Arm B. Ten-year OS was 61% for the entire group of patients: 64% in Arm A and 59% in Arm B. The intention-to-treat analysis confirmed that three cycles were not inferior to five cycles (one-sided 95% upper confidence limit was 1.24). A per protocol analysis was consistent with these results. Pts with leiomyosarcoma and undifferentiated pleomorphic sarcoma (UPS) had the lowest, and the highest response rates, respectively. Consistently, Leiomyosarcoma and UPS had the worse and the best prognosis, respectively., [Conclusions] At a longer FU, the non-inferiority of three cycles of a full-dose conventional CT in comparison to five is confirmed. Response to therapy is also confirmed to be associated with better survival. This regimen is currently tested within an ongoing international trial against three cycles of a neoadjuvant histology-tailored CT (ClinicalTrials.gov Identifier: NCT01710176).

Purpose: This study aimed to evaluate the efficacy and safety of the treatment with 90Y-ibritumomab tiuxetan following a short-course of rituximab with cyclophosphamide-adriamycin-vincristine-prednisone (R-CHOP) in high-risk elderly patients with previously untreated diffuse large B-cell lymphoma (DLBCL). Experimental Design: From December 2006 to October 2008, 55 high-risk elderly (age ≥60 years) untreated DLBCL patients were treated in seven Italian institutions with a short-course of chemotherapy consisting of four cycles of R-CHOP21 followed by 90Y-ibritumomab tiuxetan 6 to 10 weeks later. Results: Of the 55 patients, 48 underwent radioimmunotherapy. The overall response rate to the entire treatment regimen was 80%, including 73% complete remissions and 7% partial remissions. Eight (50%) of the 16 patients who achieved less than a complete response with CHOP improved their remission status after 90Y-ibritumomab tiuxetan administration. With a median follow-up of 18 months, the 2-year progression-free survival was estimated to be 85%, with a 2-year overall survival of 86%. 90Y-ibritumomab tiuxetan toxicity consisted of grade 3 to 4 hematologic toxicity in 28 of 48 patients, mainly neutropenia (23 patients) and thrombocytopenia (15 patients). Red cells and/or platelets transfusions were given to three patients. Conclusion: This study evaluated the feasibility, efficacy, and safety of a short-course R-CHOP21 regimen followed by 90Y-ibritumomab tiuxetan in high-risk elderly DLBCL patients.

Antonia Pierobon,1 Elisa Sini Bottelli,1 Laura Ranzini,1 Claudio Bruschi,2 Roberto Maestri,3 Giorgio Bertolotti,4 Marinella Sommaruga,5 Valeria Torlaschi,1 Simona Callegari,1 Anna Giardini1 1Psychology Unit, 2Department of Pulmonary Rehabilitation, 3Department of Biomedical Engineering, Istituti Clinici Scientifici Maugeri, IRCCS, Montescano, 4Psychology Unit, Istituti Clinici Scientifici Maugeri, IRCCS, Tratate, 5Clinical Psychology and Social Support Unit, Istituti Clinici Scientifici Maugeri, IRCCS, Camaldoli, Italy Abstract: In addition to clinical comorbidities, psychological and neuropsychological problems are frequent in COPD and may affect pulmonary rehabilitation delivery and outcome. The aims of the study were to describe a COPD population in a rehabilitative setting as regards the patients depressive symptoms, anxiety, mild cognitive impairment (MCI) and self-reported adherence and to analyze their relationships; to compare the COPD sample MCI scores with normative data; and to investigate which factors might predict adherence to prescribed physical exercise. This was a multicenter observational cross-sectional study. Of the 117 eligible stable COPD inpatients, 84 were enrolled according to Global initiative for chronic Obstructive Lung Disease (GOLD) criteria (mainly in Stage III–IV). The assessment included Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), anxiety, depression and self-reported pharmacological and nonpharmacological adherence. From the MMSE, 3.6% of patients were found to be impaired, whereas from the MoCA 9.5% had a likely MCI. Patients referred had mild-severe depression (46.7%), anxiety (40.5%), good pharmacological adherence (80.3%) and difficulties in following prescribed diet (24.1%) and exercise (51.8%); they struggled with disease acceptance (30.9%) and disease limitations acceptance (28.6%). Most of them received good family (89%) or social (53%) support. Nonpharmacological adherence, depression, anxiety and MCI showed significant relations with 6-minute walking test, body mass index (BMI) and GOLD. Depression was related to autonomous long-term oxygen therapy modifications, disease perception, family support and MCI. In the multivariate logistic regression analysis, higher BMI, higher depression and lower anxiety predicted lower adherence to exercise prescriptions (P=0.0004, odds ratio=0.796, 95% CI=0.701, 0.903; P=0.009, odds ratio=0.356, 95% CI=0.165, 0.770; and P=0.05, odds ratio=2.361, 95% CI=0.995, 5.627 respectively). In COPD patients, focusing on pharmacological and nonpharmacological adherence enhance the possibility of tailored pulmonary rehabilitation programs.

BACKGROUND: Preclinical studies have highlighted the activity of lenalidomide in mantle cell lymphoma and its anti-proliferative synergy with dexamethasone. DESIGN AND METHODS: In this prospective, multicenter, phase II study, patients with relapsed/refractory mantle cell lymphoma who were not eligible for, or had relapsed after, intensive treatments received lenalidomide 25 mg/day (days 1-21 of each 28-day cycle) and dexamethasone (40 mg/day on days 1, 8, 15, and 22) for up to 12 months. RESULTS: The primary end-points, overall and complete response rates, were achieved by 17 of 33 (52%; 95% confidence interval [CI], 35-68%) and 8 of 33 patients (24%; 95% CI, 13-41%), respectively, by the end of treatment. Fifteen patients (45%) discontinued treatment prematurely, 13 due to lack of response. The median progression-free and overall survival were 12 months (95% CI, 5-19 months) and 20 months (95% CI, 12 months to not estimable), respectively. Treatment resulted in a significant increase in microvessel density (P=0.033) and non-significant increases in macrophage and natural killer cell counts, while serum levels of neoangiogenic factors did not change significantly. Grade 3/4 adverse events were neutropenia (53%), leukopenia (25%), thrombocytopenia (22%), infections (12%), and febrile neutropenia (12%). CONCLUSIONS: These results confirm a favorable safety and activity profile of lenalidomide in relapsed/refractory mantle cell lymphoma. The contribution of dexamethasone in achieving these results is unclear because of its possible detrimental effect on the immune activation generated by lenalidomide and a higher risk of developing infectious complications.

In 2003 the Fondazione Italiana Linfomi (FIL) started a clinical research program for investigating initial treatment of frail elderly patients with diffuse large B-cell lymphoma (DLBCL) identified by Comprehensive Geriatric Assessment (CGA). From 2003 to 2006, 334 elderly patients underwent CGA assessment, and 99 patients were classified as frail. Frail patients had a median age of 78 years, stage III-IV disease in 62% and age-adjusted International Prognostic Index (aaIPI) of 2-3 in 53%. Treatment consisted of several different regimens according to physician discretion. After a median follow-up of 36 months, 5-year overall survival (OS) was 28%. In multivariate analysis, aaIPI 2-3 (p = 0.005) and the presence of respiratory comorbidity (p = 0.044) were the only factors that showed independent correlation with OS. Frail patients had a poorer outcome compared with fit patients also if they were treated with rituximab-containing combination chemotherapy (hazard ratio 2.37, 95% confidence interval 1.48-3.78; p < 0.001). CGA is a valid tool to prospectively identify frail subjects among elderly patients with DLBCL.

Purpose We report on feasibility of preoperative chemotherapy with or without radiation therapy (RT) in the context of a phase III randomized clinical trial involving localized, high-risk, soft tissue sarcomas. Patients and Methods Of 321 eligible patients, 161 were randomly assigned to three preoperative cycles of epirubicin 120 mg/m2 plus ifosfamide 9 g/m2, and 160 were randomly assigned to three preoperative plus two postoperative cycles. Among them, 303 patients were included in this analysis; 169 were male and 134 were female, with a median age of 48 years (range, 15 to 79 years). One hundred fifty-two patients received concurrent RT preoperatively at a total dose of 44 to 50 Gy. Preoperative chemotherapy-related hematologic toxicity and early postoperative complications were reported. The influence of RT, age, and sex on hematologic grade 3 or 4 toxicities and wound complications was analyzed. Chemotherapeutic dose intensity (DI) was analyzed. Results Among the patients, 61.4%, 22.4%, and 23.8% experienced, grade 4 leucopenia, grade 3 or 4 anemia, and grade 3 or 4 thrombocytopenia, respectively. Respective rates were 66.4%, 24.3%, and 31.6% when RT was added preoperatively, and 56.3%, 20.5%, and 15.9% when preoperative chemotherapy was administered alone. Patient age affected grade 3 or 4 thrombocytopenia. Grade 4 leucopenia and grade 3 or 4 anemia presented 2.5 times more frequently in female patients than in male patients. Wound complications were observed in 13.5% of patients: 17% with preoperative RT and 10% without. Chemotherapeutic DI was greater than 90%, even in patients receiving preoperative RT and in patients age 65 years or older. Conclusion This preoperative chemotherapy is feasible and can also be proposed for selected elderly patients. Grade 3 or 4 hematologic toxicity was common, but DI was excellent. Concurrent preoperative RT is safe, although an increased rate of grade 4 thrombocytopenia and limited increase in wound complications may be observed.

Objective To test the hypothesis that dysfunctional metacognitions might be a general vulnerability factor for anxiety disorder, metacognitive beliefs among patients with obsessive-compulsive disorder (OCD), patients with panic disorder (PD), and healthy subjects (HS) were studied. Correlations between metacognitive beliefs, OCD, and PD symptoms were also investigated. Methods Patients with OCD (n = 114), patients with PD (n = 119), and HS (n = 101) were assessed with the Metacognition Questionnaire (MCQ). Results Patients with OCD and those with PD scored significantly higher than HS on the MCQ in 2 dimensions: negative beliefs about worry concerning uncontrollability and danger as well as beliefs about the need to control thoughts dimensions. No difference in MCQ scores was observed between the OCD and PD groups. The former 2 MCQ dimensions were positively correlated with the degree of indecisiveness in patients with OCD, whereas the MCQ negative beliefs about worry positively correlated with the average intensity of anticipatory anxiety in patients with PD. Conclusions The presence of dysfunctional metacognitions in both patients with OCD and those with PD suggests that such beliefs can represent not only generic vulnerability factors for anxiety disorders but also elements that contribute to maintaining the disorder, as evidenced by their associations with aspects of OCD and PD symptoms.

Introduction Chronic obstructive pulmonary disease (COPD) is a complex multi-component disorder characterized by progressive irreversible respiratory symptoms and extrapulmonary comorbidities, including anxiety-depression and mild cognitive impairment (MCI). However, the prevalence of these impairments is still uncertain, due to non-optimal screening methods. This observational cross-sectional multicentre study aimed to evaluate the prevalence of anxiety-depressive symptoms and MCI in COPD patients, identify the most appropriate cognitive tests to screen MCI, and investigate specific cognitive deficits in these patients and possible predictive factors. Materials and methods Sixty-five stable COPD inpatients (n = 65, aged 69.9±7.6 years, mainly stage III–IV GOLD) underwent the following assessments: Hospital Anxiety and Depression Scale (HADS), Geriatric Depression Scale (GDS) or Beck Depression Inventory-II (BDI-II), Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and a complete neuropsychological battery (ENB-2) including different cognitive domains (attention, memory, executive functions, and perceptive and praxis abilities). Results Moderate-severe anxiety was present in 18.5% of patients and depressive symptoms in 30.7%. The prevalence of MCI varied according to the test: 6.2% (MMSE), 18.5% (MoCA) and 50.8% (ENB-2). In ENB-2, patients performed significantly worse compared to Italian normative data on digit span (5.11±0.9 vs. 5.52±1.0, p = 0.0004), trail making test-B (TMT-B) (176.31±99.5 vs. 135.93±58.0, p = 0.004), overlapping pictures (26.03±8.9 vs. 28.75±8.2, p = 0.018) and copy drawing (1.370.6 vs. 1.61±0.5, p = 0.002). At logistic regression analysis, only COPD severity (p = 0.012, odds ratio, OR, 4.4 [95% CI: 1.4–14.0]) and anxiety symptoms (p = 0.026, OR 4.6 [1.2–17.7]) were significant and independent predictors of the deficit in copy drawing, which assesses visuospatial and praxis skills. Conclusion Given the prevalence of neuropsychological impairments in COPD patients, the routine adoption in rehabilitation of screening tools for mood and cognitive function, including digit span, TMT-B and copy drawing, may be useful to detect psychosocial comorbidities and personalize the rehabilitative program.

[18F]fluorodeoxyglucose-positron emission tomography (PET) is emerging as a strong diagnostic and prognostic tool in follicular lymphoma (FL) patients.In a subset analysis of the FOLL05 trial (NCT00774826), we investigated the prognostic role of post-induction PET (PI-PET) scan. Patients were eligible to this study if they had a PI-PET scan carried out within 3 months from the end of induction immunochemotherapy. Progression-free survival (PFS) was the primary study end point.A total of 202 patients were eligible and analysed for this study. The median age was 55 years (range 33-75). Overall, PI-PET was defined as positive in 49 (24\%) patients. Conventional response assessment with CT scan was substantially modified by PET: 15\% (22/145) of patients considered as having a complete response (CR) after CT were considered as having partial response (PR) after PI-PET and 53\% (30/57) patients considered as having a PR after CT were considered as a CR after PI-PET. With a median follow-up of 34 months, the 3-year PFS was 66\% and 35\%, respectively, for patients with negative and positive PI-PET (P

An update at 7 years was conceived for our multicenter phase II study in which 55 elderly high-risk untreated diffuse large B-cell lymphoma patients were treated with 90Y-ibritumomab tiuxetan after a short course of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) as long-term follow-up analyses of this combined therapeutic modality are lacking. The overall response rate to the entire regimen was 80%, including 73% (40/55) of complete response (CR) rate and 7% (4/55) of partial response rate. At the time of writing, 24/55 (43.6%) patients experienced a progression disease and 20 of 40 (50%) patients who obtained a CR are still alive in continuous CR. With a median follow-up of 7 years, the disease-free survival was 43.3% and the progression-free survival was 36.1%. The overall survival at 7.9 years was 38.9% (27 deaths mainly because of lymphoma). Two patients developed secondary hematological malignancies, an acute myeloid leukemia and a myelodysplastic syndrome, at 4 and 3 years from radioimmunotherapy, respectively. Our data confirm the feasibility, efficacy and safety of four cycles of R-CHOP followed by radioimmunotherapy consolidation even in the long term: this combination allows dispensing less chemotherapy in a frail group of patients without invalidating response quality and duration.

Extranodal marginal zone B-cell lymphomas are linked to bacterial infections that vary according to the anatomical site. The occurrence of these lymphomas in the central nervous system is a very rare event, and the identification of specific bacteria in this setting has not been previously addressed. Herein, we report for the first time a case of primary central nervous system marginal zone B-cell lymphoma involving the choroid plexus associated with Chlamydophila psittaci infection. No concomitant ocular involvement was detected. C psittaci was identified with 3 independent methods, and through immunohistochemistry, it was visualized in the cytoplasm of monocytes/macrophages present within lymphomatous tissues. This observation points toward the opportunity to investigate the prevalence of C psittaci infection in central nervous system lymphomas, particularly in those with low-grade histologic features.

Follicular lymphoma (FL) patients experience multiple remissions and relapses and commonly receive multiple treatment lines. A crucial question is whether anthracyclines should be used at first-line or whether they would be better "reserved" for relapse and whether FL outcome can be optimized by definite sequences of treatments. Randomized trials can be hardly designed to address this question. In this retrospective multi-institutional study, time-to-next-treatment after first relapse was analyzed in 510 patients who had received either alkylating agents- or anthracycline- or nucleoside analogs-based chemotherapy with/without rituximab at first-line and different second-line therapies. After a median of 42 months, median time-to-next-treatment after relapse was 41 months (CI95%:34-47 months). After adjustment for covariates, first-line anthracycline-based chemotherapy with/without rituximab was associated with better time-to-next-treatment after any salvage than alkylating agents-based chemotherapy with/without rituximab or nucleoside analogs-based chemotherapy with/without rituximab (HR:0.74, P = 0.027). The addition of rituximab to first-line chemotherapy had no significant impact (HR:1.22, P = 0.140). Autologs stem cell transplantation performed better than any other salvage treatment (HR:0.53, P 0.001). First-line anthracycline-based chemotherapy significantly improved time-to-next-treatment even in patients receiving salvage autologs stem cell transplantation (P = 0.041). This study supports the concept that in FL previous treatments significantly impact on the outcome of subsequent therapies. The outcome of second-line treatments, either with salvage chemoimmunotherapy or with autologs stem cell transplantation, was better when an anthracycline-containing regimen was used at first-line.

High-dose chemotherapy with autologous stem cell transplantation (ASCT) has been shown effective in the control of relapsed/refractory follicular lymphoma. We evaluate the long-term outcome of patients with relapsed or refractory follicular lymphoma treated with ASCT with in vivo purged progenitors cells. We report the long-term results of a prospective multicenter phase 2 trial on 124 relapsed/refractory follicular lymphoma patients treated with a program of anthracycline-based debulking chemotherapy, immunochemotherapy, mobilization of in vivo purged PBSC followed by ASCT. Median age was 52 years; 14% of patients had grade 3A histology. Debulking chemotherapy produced CR in 16% and PR in 71%, while 13% of patients progressed. After rituximab, cyclophosphamide, vincristine, prednisone (R-COP), CR was obtained in 60% and PR in 35%; 118 patients successfully mobilized PBSC and 117 proceeded to ASCT. The harvest in all the 32 molecularly informative patients was bcl-2 negative. TRM was 0%. The 5-year PFS was 54% and the 5-year OS was 83%. After a median f-up of 6.7 years (range 1.5-13.6), 54% are still in CR. These data show that prolonged PFS is achievable in relapsed/refractory patients with high dose autologous transplantation of in vivo purged progenitor cells.

Background: To evaluate the clinical outcome of patients with relapsed or refractory follicular lymphoma treated with immunochemotherapy, in vivo purging and high-dose therapy with autotransplant. Patients and methods: Sixty-four patients were enrolled in the trial. Primary end point was progression-free survival (PFS). Secondary end points were the in vivo purging effect on stem-cell harvest and the impact of molecular response on the outcome. Results: At enrollment, 59% of patients were PCR+ for bcl-2 rearrangement in bone marrow (PCR-informative). After the immunochemotherapy, before mobilization, 97% obtained complete response or partial response and 87% of patients informative for bcl-2 were molecularly negative. Sixty-one patients proceeded to in vivo purging and peripheral blood stem cell (PBSC) mobilization with rituximab and high-dose AraC. The median number of CD34+ cells collected was 16.6 · 10 6 /kg. Of 33 PCR-informative patients, the harvests resulted in PCR2 in all. Fifty-eight patients received high-dose therapy and autotransplant of in vivo purged PBSC. After a median follow-up of 3.5 years, 41 patients are in complete remission. Five-year PFS is 59%. Conclusion: This study demonstrates that patients with advanced relapsed or refractory follicular lymphoma treated with immunochemotherapy, in vivo purging and autotransplant may obtain long-lasting PFS. In bcl-2-positive patients, in vivo purging allows the harvest of lymphoma-free PBSC. Absence of the bcl-2 rearrangement after autotransplant is associated with persistent clinical remission.

Between December 1985 and February 1995, 260 orthotopic liver transplantations (OLTX) were performed on 238 patients at Niguarda Hospital. Sixty-three patients had hepatocellular carcinoma (HCC); in 13 of the patients HCC was incidental. All patients had negative lymph nodes. According to the Child classification, 13 patients were Child A, 30 Child B, and 18 Child C. According to the TNM classification, 11 patients were stage I, 22 stage II, 15 stage III, and 15 stage IVa. Pre-OLTX chemoembolization was performed on 25 patients. The perioperative mortality rate was 27% (17 patients). Overall survival and disease-free actuarial survival rates at 1, 3, and 5 years were 94%, 76%, 76%, and 83%, 75%, 75%, respectively. Survival curves were compared for 16 different variables. No difference was observed for all parameters analyzed except tumor site, TNM stage, pre-OLTX AFP levels and vascular infiltration. These results seem to demonstrate that the OLTX for unresectable HCC can be considered in specifically selected cases as the treatment of choice. An adequate tumor staging is also necessary for a better patient selection in order to increase survival.

Despite improvements in standard therapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone for patients with untreated, diffuse large B-cell lymphoma, up to 40% of these patients relapse. Lenalidomide alone or in combination with rituximab has been shown to be active in relapsed/refractory aggressive lymphomas. In this phase I study we determined the maximum tolerated dose of lenalidomide plus rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone in untreated, elderly (median age 68 years) patients with diffuse large B-cell lymphoma. Four lenalidomide doses (5, 10, 15, and 20 mg/day on days 1-14) allocated using the continual reassessment method were planned to be administered for 14 days in combination with each course of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone for a total of six courses. Seven cohorts of patients (n=3 in each cohort) were treated (total n=21) at 10, 20, 15, 15, 15, 10, and 10 mg of lenalidomide. Dose-limiting toxicities occurred in seven patients during the first three courses of treatment. The third dose-level of lenalidomide (15 mg/day) was selected as the maximum tolerated dose, with an estimated probability of dose-limiting toxicities of 0.345 (95% credibility interval 0.164-0.553). Grade 3-4 hematologic adverse events were: neutropenia in 28% of the courses, thrombocytopenia in 9%, and anemia in 3%. Non-hematologic toxicities were moderate: grade 4 increase of creatinine phosphokinase (n=1), grade 3 cardiac (n=2), grade 3 neurological (n=3), and grade 3 gastrointestinal (n=1). In this phase I study, the overall response rate was 90%, with 81% achieving complete remission. This combination regimen appears safe in elderly patients with diffuse large B-cell lymphoma and its efficacy will be assessed in the ongoing phase II trial. This trial was registered at www.clinicaltrials.gov as NCT00907348.

Viral genotypes have been associated with different severity and outcome of hepatitis C virus (HCV)-related liver disease. The aim of this study was to determine whether HCV genotypes may influence the cirrhosis-related risk of the development of hepatocellular carcinoma (HCC).Three groups of patients were studied: 593 patients with chronic hepatitis, 166 patients with HCC and cirrhosis, and 219 patients with cirrhosis but without HCC. A cross-sectional study of frequency distribution and a case-control analysis were performed. HCV genotypes were detected according to Okamoto.HCV type 1b infection was more prevalent among patients with HCC compared with patients with cirrhosis but without HCC (P0.01) and chronic hepatitis (P0.001). Age, male sex, and HCV type 1b significantly influenced the risk of cancer in cirrhosis by univariate analysis. A pairwise comparison performed on 162 patients with HCC and an equal number of patients with cirrhosis matched by age, sex, and Child's class showed that HCV type 1b was independently associated with HCC (odds ratio, 1.7; P = 0.026).HCV type 1b is overrepresented in patients with cirrhosis and HCC and significantly influences the risk of HCC in cirrhosis, independent of sex, age, and Child's class.

We assessed the prognostic value of minimal residual disease (MRD) within the ML17638 phase 3 trial from the Fondazione Italiana Linfomi, investigating the role of rituximab maintenance in elderly follicular lymphoma (FL) patients after a brief first-line chemoimmunotherapy. MRD for the bcl-2/IgH translocation was determined on bone marrow cells in a centralized laboratory belonging to the Euro-MRD consortium, using qualitative and quantitative polymerase chain reactions (PCRs). Of 234 enrolled patients, 227 (97%) were screened at diagnosis. A molecular marker (MM) was found in 51%. Patients with an MM were monitored at 8 subsequent times. Of the 675 expected follow-up samples, 83% were analyzed. Conversion to PCR negativity predicted better progression-free survival (PFS) at all post-treatment times (eg, end of therapy: 3-year PFS, 72% vs 39%; P < .007). MRD was predictive in both maintenance (83% vs 60%; P < .007) and observation (71% vs 50%; P < .001) groups. PCR positivity at the end of induction was an independent adverse predictor (hazard ratio, 3.1; 95% confidence interval, 1.36-7.07). MRD is a powerful independent outcome predictor in FL patients who receive rituximab-intensive programs, suggesting a need to investigate its value for decision-making. This trial was registered at www.clinicaltrial.gov as #NCT01144364.

A total of 84 patients with hepatocellular carcinoma and cirrhosis were analyzed retrospectively to investigate prognostic factors. All patients received transarterial oily chemoembolization as the only anticancer therapy. The follow-up range was 1 to 39 mo (median, 9.5 mo). The overall actuarial survival rates at 12, 24 and 30 mo were 62%, 31% and 24%, respectively. According to univariate analysis, variables significantly associated with survival were age, Child-Pugh grade, total serum bilirubin, Okuda stage, tumor size, degree of labeling of the tumor with Lipiodol, gelatin foam use, changes with treatment in tumor size and changes with treatment in α-fetoprotein concentration. Two multivariate analyses were performed. When pretreatment and treatment variables were considered, parameters with independent prognostic value were age, Child-Pugh grade, total serum bilirubin, tumor size and degree of Lipiodol labeling of the tumor. When follow-up variables were also considered, we (a) confirmed the prognostic significance of all these parameters (age, Child-Pugh grade, total serum bilirubin, tumor size) and (b) found the independent prognostic value of the change in tumor size (or change in α-fetoprotein concentration). Both models yielded different risk coefficients for each class of each variable. Two simple prognostic indexes, based on these coefficients, are proposed: an “initial” index (including pretreatment and treatment variables) and a “follow-up” index (also including follow-up variables). According to the two indexes, the patients were classified into three groups with different prognoses: good (93% and 100% actuarial survival at 1 yr for the initial and follow-up indexes, respectively), intermediate (65% and 53%, respectively) and poor (27% for both indexes).

Objective Populations at high risk for panic disorder (PD) probably share with subjects with PD an underlying vulnerability involving features like anxiety sensitivity (AS) and alexithymia. The present study would verify if PD relatives (R) and subjects who have experienced 1 or more panic attacks (PAs) show different levels of AS and alexithymia with respect to healthy controls (HC). Methods One hundred fifty-seven HCs, 30 subjects with PA, 64 R subjects, and 139 outpatients with PD were evaluated and compared on AS, alexithymia, and control variables. Results Subjects with PD show higher alexithymia and AS levels compared with HCs; R subjects do not differ on ASI total score; and R females show more alexithymic features. Subjects with PA are comparable with HCs both on AS and alexithymia. Conclusions Results confirm an impairment in emotional and bodily sensations information processing in subjects with PD but partially disconfirm the expectation of a difference between R subjects and subjects with PA with respect to HCs on AS and alexithymia. Emotional and bodily sensation competencies could be protective factors for PD in high-risk populations.

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-associated mortality. Antibodies against human leucocyte antigens (HLA) and human neutrophil antigens (HNA) are often detected in the implicated donors. We investigated the incidence and aetiology of TRALI in Lombardy. Moreover, we determined the rate of HLA and HNA alloimmunisation and the HNA genotype in a cohort of local blood donors.During a 2-year observational study in eight blood transfusion services, suspected TRALI cases were collected and characterised by means of HLA and HNA antibody screening of implicated donors, donor/recipient cross-matching and HLA/HNA molecular typing. In addition, 406 Italian donors were evaluated for alloimmunisation and in 102 of them HNA gene frequencies were determined.Eleven cases were referred to the central laboratory, of whom three were diagnosed as having TRALI, seven as having possible TRALI and one as having transfusion-associated circulatory overload. Seven TRALI cases were immune-mediated whereas in three we did not find either alloantibodies in implicated donors or a positive reaction in the cross-match. The most frequently implicated blood component was red blood cells (in 5 males and in 1 female), whereas four cases of TRALI were associated with transfusion of fresh-frozen plasma (in 3 females and in 1 male). The frequency of reported TRALI/possible TRALI cases was 1:82,000 for red blood cells and 1:22,500 for fresh-frozen plasma. No cases were observed for platelets. Overall, the frequency of HLA or HNA alloimmunisation in blood donors was 29% for females and 7% for males. The latter could be related, at least in part, to natural antibodies. HNA gene frequencies showed that HNA-1b is more frequent than HNA-1a in our sample of donors.The recently adopted national policy to prevent TRALI, i.e. using only plasma donated by males, would have had a positive impact in our setting.

BACKGROUND: The authors set out to analyze if a simple comprehensive geriatric assessment (CGA) could objectively identify elderly patients with diffuse large cell lymphoma (DLCL) who can be effectively treated with anthracycline-containing immunochemotherapy. METHODS: CGA was performed in 84 consecutive patients with DLCL aged >65 years and diagnosed at a single institution. Treatment with curative versus palliative intent was chosen according to clinical judgment. Cyclophosphamide, hydroxydaunomycin, Oncovin (vincristine), and prednisone (CHOP) or CHOP-like regimens were given to 62 (74%) patients. The outcome of patients was analyzed according to both the treatment received and the results of CGA. RESULTS: According to CGA, 42 (50%) patients were classified as “fit.” They were younger (P < .0001) and had less frequent systemic symptoms (P = .03). These patients received curative treatment by clinical judgment. Their response rate (92.5% vs 48.8%; P < .0001) and median survival (not reached vs 8 months; P < .0001) were significantly better than those of 42 patients considered “unfit” by CGA. Among unfit patients, 20 had actually received curative and 22 palliative therapy. These subgroups did not differ in any geriatric or lymphoma-related characteristic. Their outcome was similar irrespectively of the type of treatment received (median survival, 8 vs 7 months; P = nonsignificant). Lymphoma rather than toxicity was the main cause of failure/death also among unfit patients treated aggressively. CONCLUSIONS: CGA is an efficient method to identify elderly DLCL patients who can benefit from a curative approach with anthracycline-containing immunochemotherapy. Further study is needed to discern why unfit patients seem to have poor outcomes because of poor tolerance but also because of lymphoma refractoriness to intensive therapy.

An unclassified amicrobial pustular dermatosis particularly affecting the main cutaneous folds, external auditory canals and scalp and coexisting with systemic lupus erythematosus has been recently described.We studied 3 young females bearing such cutaneous manifestations in association with subacute cutaneous lupus erythematosus, celiac disease and various serum autoantibodies, respectively, in order to further characterize this possibly new entity.Various routine and immunological laboratory tests, histopathologic and direct immunofluorescence examinations and in vitro studies of neutrophil function were performed in each patient.We reported our findings and compared our cases with the few others appearing in the literature. We documented an impaired neutrophil chemotaxis in 2 subjects, but neutrophil dysfunction does not seem to be one of the verifying criteria.All of these cases may represent a distinctive form in the clinicopathological spectrum of neutrophilic dermatoses (ND) because of the typical distribution and the close link with different autoimmune disorders. Cimetidine in combination with ascorbic acid can be indicated as an effective and safe alternative to the classic medications of ND, although the action of both drugs remains unexplained.

220-kDa ankyrin-B is required for coordinated assembly of Na/Ca exchanger, Na/K ATPase, and inositol trisphosphate (Ins P 3 ) receptor at transverse-tubule/sarcoplasmic reticulum sites in cardiomyocytes. A loss-of-function mutation of ankyrin-B identified in an extended kindred causes a dominantly inherited cardiac arrhythmia, initially described as type 4 long QT syndrome. Here we report the identification of eight unrelated probands harboring ankyrin-B loss-of-function mutations, including four previously undescribed mutations, whose clinical features distinguish the cardiac phenotype associated with loss of ankyrin-B activity from classic long QT syndromes. Humans with ankyrin-B mutations display varying degrees of cardiac dysfunction including bradycardia, sinus arrhythmia, idiopathic ventricular fibrillation, catecholaminergic polymorphic ventricular tachycardia, and risk of sudden death. However, a prolonged rate-corrected QT interval was not a consistent feature, indicating that ankyrin-B dysfunction represents a clinical entity distinct from classic long QT syndromes. The mutations are localized in the ankyrin-B regulatory domain, which distinguishes function of ankyrin-B from ankyrin-G in cardiomyocytes. All mutations abolish ability of ankyrin-B to restore abnormal Ca 2+ dynamics and abnormal localization and expression of Na/Ca exchanger, Na/K ATPase, and Ins P 3 R in ankyrin-B +/- cardiomyocytes. This study, considered together with the first description of ankyrin-B mutation associated with cardiac dysfunction, supports a previously undescribed paradigm for human disease due to abnormal coordination of multiple functionally related ion channels and transporters, in this case the Na/K ATPase, Na/Ca exchanger, and Ins P 3 receptor.

Mutations in potassium-channel genes KCNQ1 (LQT1 locus) and KCNH2 (LQT2 locus) and the sodium-channel gene SCN5A (LQT3 locus) are the most common causes of the long-QT syndrome. We stratified risk according to the genotype, in conjunction with other clinical variables such as sex and the length of the QT interval.We evaluated 647 patients (386 with a mutation at the LQT1 locus, 206 with a mutation at the LQT2 locus, and 55 with a mutation at the LQT3 locus) from 193 consecutively genotyped families with the long-QT syndrome. The cumulative probability of a first cardiac event, defined as the occurrence of syncope, cardiac arrest, or sudden death before the age of 40 years and before the initiation of therapy, was determined according to genotype, sex, and the QT interval corrected for heart rate (QTc). Within each genotype we also assessed risk in the four categories derived from the combination of sex and QTc (500 msec oror =500 msec).The incidence of a first cardiac event before the age of 40 years and before the initiation of therapy was lower among patients with a mutation at the LQT1 locus (30 percent) than among those with a mutation at the LQT2 locus (46 percent) or those with a mutation at the LQT3 locus (42 percent) (P0.001 by Fisher's exact test). Multivariate analysis showed that the genetic locus and the QTc, but not sex, were independent predictors of risk. The QTc was an independent predictor of risk among patients with a mutation at the LQT1 locus and those with a mutation at the LQT2 locus but not among those with a mutation at the LQT3 locus, whereas sex was an independent predictor of events only among those with a mutation at the LQT3 locus.The locus of the causative mutation affects the clinical course of the long-QT syndrome and modulates the effects of the QTc and sex on clinical manifestations. We propose an approach to risk stratification based on these variables.

Factors influencing the progression of liver disease and the development of hepatocellular carcinoma (HCC) in chronic hepatitis C virus (HCV) infection are poorly understood. Inherited variations of drug-metabolizing enzyme (DME) activities may affect liver damage and cancer risk by modifying individual susceptibility to endogenous or exogenous toxic compounds. We investigated the association of liver disease severity with common alleles of microsomal epoxide hydrolase (mEH), an enzyme involved in the metabolism of highly reactive epoxide intermediates. Three polymorphisms (Tyr113His, His139Arg, and -613C/T) were analyzed by polymerase chain reaction (PCR) restriction fragment length polymorphisms (RFLPs) in 394 patients at different stages of disease, including 92 asymptomatic carriers, 109 patients with chronic hepatitis, 100 patients with cirrhosis, and 93 patients with HCC. Reference allele frequencies were obtained from 99 healthy blood donors. Allele distributions between categories were compared using the chi(2) test; odds ratios (ORs) and 95% CI were calculated to express relative risks. Allele frequencies among 99 healthy controls were as follows: 15.1% for 113His/His, 4.0% for 139Arg/Arg, and 46.5% for -613C/T. mEH 113His/His homozygotes were overrepresented in advanced stages of disease, in particular among HCC patients (27.9%; P =.03; OR, 2.2; 95% CI, 1.0-4.6). Differences were more pronounced among men and between extreme patient categories. When mEH genotypes were combined to express a metabolic phenotype, very slow metabolizers were highly prevalent among cirrhotic and HCC patients (18% vs. 3.3% in carriers; P.001). In conclusion, mEH gene polymorphisms were significantly associated with HCV-related liver disease severity and HCC risk. Men were at higher risk than women; this might be explained by hormonal regulation of gene expression or by differential exposure to environmental toxins.

Paired sera and liver biopsies from 105 patients with chronic hepatitis B virus infection (34 HBeAg positive and 71 anti-HBe positive) were studied to investigate the relation between the degree of histological activity and alanine aminotransferase (ALT), hepatitis B virus DNA (HBV-DNA) or IgM antibody to hepatitis B core antigen (IgM anti-HBc) levels. ALT levels were significantly higher in patients with piecemeal necrosis (155 +/- 124 vs 75 +/- 42, p = 0.0017), but there were no differences in the ALT values of patients with or without intralobular necrosis. ALT values were within normal range in 29% of 31 patients without versus 15% of 65 with piecemeal necrosis (p = 0.19). Serum HBV-DNA levels were not related to the grade of lobular or portal/periportal activity in HBeAg-positive patients. Anti-HBe-positive subjects with piecemeal necrosis had higher HBV-DNA levels (34 +/- 93 vs 4 +/- 6, p = 0.01). IgM anti-HBc indexes were significantly higher in patients with intralobular necrosis (0.635 +/- 0.600 vs 0.356 +/- 0.367, p = 0.0005) or piecemeal necrosis (0.671 +/- 0.633 vs 0.321 +/- 0.219, p = 0.0002). In summary, since serum IgM anti-HBc-IMx indexes can reflect the grade of histological activity, the quantitative assessment of this antibody could be useful for non-invasive monitoring of hepatocellular damage in chronic hepatitis B.

Total serum cholesterol levels have been studied in 100 patients with histological diagnoses of chronic hepatitis B and 100 wit chronic Hepatitis C, all without cirrhosis, and two age- and sex-matched control groups (B and C). Mean serum cholesterol levels of the groups were compared also in relation to sex, liver function, duration of the disease, alcohol intake, mass index, liver enzymes, presence of liver steatosis and severity of the liver disease on the basis of the histological activity index. The percentages of patients with serum cholesterol level150 mg/dl and240 mg/dl were also calculated. The mean serum cholesterol level was significantly lower in hepatitis C: 176 md/dl vs 194 mg/dl of hepatitis B (p = 0.004) and 198 of control C (p = 0.000). Twenty eight hepatitis C patients had serum cholesterol150 mg/dl vs 10 with hepatitis B (p = 0.001). In multivariate regression analysis, only the type of virus infection was independent related to serum cholesterol level (p = 0.0063).

Efficacy and safety of therapy with lymphoblastoid interferon-alpha alone or combined with deflazacort has been investigated in 38 HBsAg-HBeAg+ patients with biopsy-proven chronic hepatitis. Group I received 5 MU/m2 interferon thrice a week for 26 weeks; group II took interferon for 26 weeks simultaneously with a 6-week course of deflazacort. Follow-up was 18-72 months (median 42). After 12 months, responses were achieved in 3 (18%) out of 17 patients on interferon alone vs 5 (26%, p0.05) out of 19 on combined therapy. Blind histological assessment revealed no improvement in either group or in patients who responded to therapy within the first year of follow-up ("early responders"). "Delayed" responses were observed in 4 (29%) patients who took interferon alone vs 5 (36%, p0.05) who took the combined therapy. Serum HBV DNA levels decreased significantly during treatment and remained low up to 24 and 36 months of follow-up in both groups. One early responder developed hepatocellular carcinoma, another had exacerbation of liver disease in long-term follow-up. No non-responders developed liver failure or hepatocellular carcinoma. These results indicate that lymphoblastoid interferon-alpha inhibits HBV replication and corticosteroids have no synergistic effect in treatment of HBsAg-HBeAg+ chronic hepatitis.

We aimed to test the hypothesis that susceptibility to chronic HBV, HDV and HCV infections or their pathology is influenced by host genetic factors.The Human Leukocyte Antigens (HLA) (A, B, DR and DQ) were determined by microlymphocytotoxicity assay in patients with chronic C (n = 117), B (n = 97) or D (n = 27) hepatitis and their frequencies were compared with those of 489 healthy controls.No statistically significant association was found between any HLA antigen and chronic B or D hepatitis. A significantly higher frequency of HLA-B14 was observed in patients with chronic persistent or active C hepatitis (16.7% of 90 versus 5.9% of 489, chi(2) = 10.9, pc0.05, Relative Risk = 3.17, Etiological Fraction = 0.11). The frequency of HLA-DR5 was lower in HCV positive patients (24.8%) than in controls (45%, chi(2) = 15.1, pc0.005, RR = 0.4, EF = -0.37).No correlation could be observed between clearance of HBV or HDV and HLA phenotype. Immunogenetic factors may have a role in determining susceptibility to chronic HCV hepatitis, and in Italian patients HLA-DR5 is a protective factor.

Inflammatory pseudotumour is a rare pathologic lesion, of unknown aetiology, rarely involving the liver. Resection seems to be the treatment of choice and it is generally associated with a good prognosis. Histologically, these processes appear to be benign, nevertheless, aggressive courses or recurrences of inflammatory pseudotumour with tumor-like deaths have been reported. The cases of two patients are described who underwent hepatic lobectomy for a liver mass that was diagnosed as liver inflammatory pseudotumour at the initial histopathological assessment: albeit a malignant course followed and both the patients died cachectic. One patient, a 39-year-old man, had an unusually aggressive clinical course and recurrence of the disease with multiple hepatic masses and extension into the thorax six years later. In the other case, in a 28-year-old woman, the hepatic lesion was identified as a low-grade hepatic sarcoma only seven years after surgery.

Between January 1989 and June 1997, 533 patients (423 male, 110 female, mean age 61 years, range 22-89 years) with hepatocellular carcinoma (HCC) were observed at our center. We report on 419 patients retrospectively compared for different treatments: liver transplantation (LT; 55 patients), resective surgery (RS; 41 patients), transarterial chemoembolization (TACE; 171 patients) and percutaneous ethanol injection (PEI; 152 patients). The 3- and 5-year actuarial survival rates were, respectively, 72% and 68% for LT, 64 and 44% for RS, 54 and 36% for PEI, and 32 and 22% for TACE. Survival curves were compared for sex, age, tumor characteristics, alphafetoprotein level, Child class, and etiology of cirrhosis. All patient-related characteristics examined (sex, age) are not significantly related to patient survival. Tumor-related variables and associated liver disease variables significantly conditioned survival in relation to different treatments. LT seems to be the treatment of choice for monofocal HCC less then 5 cm in diameter and in selected cases of plurifocal HCC. © Springer-Verlag 1998

Severe fractures of the lower end of the femur have increased in frequency as road accidents have become more common. Good anatomical reconstruction is essential in order to conserve useful joint function, and this can only be achieved by internal fixation. Judet's screw-plate has been used with success in these cases and is presented in its technical and clinical aspects. The quality of the results obtained is documented in an analysis of 22 operations.

Immunologic studies were performed in 83 patients with Down's Syndrome (DS) in ages ranging from a few months to 30 years and 76 karyotypically normal age-matched controls. The results show that both thymus-dependent and independent functions were impaired in DS with a characteristic age sequence. Serum immunoglobulin levels were normal in children with DS less then 5 years old; after 6 years of age a definite hyperglobulinemia of the IgG and IgA type was observed. A slight decrease in IgM was observed between 16 and 25 years of age. In subjects with DS lymphocyte phytohemagglutinin responsiveness was in the normal range during the first decade but it decreased thereafter progressively; the percentage and absolute number of peripheral blood lymphocytes forming "spontaneous rosettes" with sheep erythrocytes were abnormally low at all ages including infancy; the number of circulating lymphocytes with a high density of surface immunoglobulins was always in the normal range.
