Background: Allogeneic transplant is an effective salvage therapy in patients with Hodgkin lymphoma (HL) relapsed or refractory (R/R) to previous treatments. In recent years, immunotherapies (conjugated antibody and checkpoint inhibitors [CPI]) showed interesting results and were used as bridge therapies to allotransplant., Aim: The aim of this retrospective study in Lazio region was to evaluate the impact of these new therapies on outcome after allogeneic hematopoietic stem cell transplantation (allo-SCT) in comparison with standard chemotherapies used in the past., Methods: We selected all consecutive patients with diagnosis of HL transplanted in four hematology transplant units, and we collected data obtained from patients' records concerning all the treatments before allo-SCT., Results: A total of 56 patients were enrolled in this study. All patients underwent allo-SCT for R/R HL. Seventeen patients (30%) received chemotherapy prior to allo-SCT (group B); they were treated between 2008 and 2015; and 39 patients (70%) received brentuximab vedotin (BV), CPI, or both before allo-SCT as a bridge to transplant (group A); they were treated between 2012 and 2020. Twenty-five patients were treated with BV alone, 2 with CPI alone, and 12 first with BV and then with CPI. No patient received concomitant BV and CPI. At 5 years from allo-SCT, overall survival (OS) was 59% and progression-free survival (PFS) was 65%. No statistical differences in OS or PFS were observed between patients in groups A and B. Relapse was significantly associated with a lower survival. The only factor associated with a reduced risk of relapse was development of any grade acute graft versus host disease (GVHD) (p > 0.02)., Conclusions: This regional real-world experience shows the changes that have taken place in the last 10 years in R/R HL using new drugs to render a patient eligible for allo-SCT. This strategy appears to guarantee an impressive disease control with an increased risk of complications, for example, aGVHD, that appear to nullify this advantage at least in part., (© 2022 S.

The incidence of non-Hodgkin lymphoma in patients 80 years of age or older is 50 times higher than in 20- to 24-year-olds. Very elderly patients are often not treated with standard immunochemotherapy because of poor performance status, comorbidities, and toxicity concerns. We retrospectively analyzed data for 29 patients diagnosed with diffuse large B-cell lymphoma or grade 3B follicular lymphoma and treated with rituximab in combination with nonpegylated liposomal doxorubicin between January 2010 and August 2015. The median age was 84 years. The overall 3-year survival, cause-specific survival, and progression-free survival rates were 46%, 55%, and 44%, respectively. Among prognostic factors, only the achievement of complete remission strongly correlated with overall survival, cause-specific survival, and progression-free survival rates. Treatment caused very mild toxicity, without treatment-related hospitalization or toxic deaths., (Copyright © 2017 John Wiley & Sons, Ltd.)

About 60% of patients with diffuse large B-cell lymphoma (DLBCL) may be cured by primary chemotherapy with an R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) regimen. Most of the rest will die of the disease, mainly due to the occurrence of tumor drug resistance. Many efforts have been made to explain the molecular mechanisms of drug resistance in patients with cancer, including those with DLBCL. This exploratory study was designed to correlate the mRNA expression levels of candidate genes mainly involved in the doxorubicin pathway (ABCB1, GSTP1, TOPO2α, BCL2, PKCβII) with the outcome of 54 patients with DLBCL undergoing a dose-dense R-CHOP regimen. After multivariate analysis, high GSTP1 (p = 0.003) and TOPO2α (p = 0.02) gene expressions were associated with shorter overall survival and progression-free survival, respectively, suggesting that these genes may represent an unfavorable prognostic factor in the case of R-CHOP treatment. These biomarkers may be useful for selecting patients eligible for personalized chemotherapy after validation in an independent set.

Purpose: To assess the role of [18F]fluorodeoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) after rituximab and anthracycline-containing chemoimmunotherapy in patients with primary mediastinal large B-cell lymphoma (PMLBCL)., Patients and Methods: Among 125 patients prospectively enrolled, 115 were eligible for central review of PET/CT scans at the completion of standard chemoimmunotherapy, by using a five-point scale. Consolidation radiotherapy (RT) was permitted and given to 102 patients., Results: Fifty-four patients (47%) achieved a complete metabolic response (CMR), defined as a completely negative scan or with residual [18F]FDG activity below the mediastinal blood pool (MBP) uptake. In the remaining 61 patients (53%), the residual uptake was higher than MBP uptake but below the liver uptake in 27 (23%), slightly higher than the liver uptake in 24 (21%), and markedly higher in 10 (9%). CMR after chemoimmunotherapy predicted higher 5-year progression-free survival (PFS; 98% v 82%; P=.0044) and overall survival (OS; 100% v 91%; P=.0298). Patients with residual uptake higher than MBP uptake but below liver uptake had equally good outcomes without any recurrence. Using the liver uptake as cutoff for PET positivity (boundary of score, 3 to 4) discriminated most effectively between high or low risk of failure, with 5-year PFS of 99% versus 68% (P<.001) and 5-year OS of 100% versus 83% (P<.001)., Conclusion: More than 90% of patients are projected to be alive and progression-free at 5 years, despite a low CMR rate (47%) after chemoimmunotherapy. This study provides a basis for using PET/CT to define the role of RT in PMLBCL., (© 2014 by American Society of Clinical Oncology.)

Some preclinical and pharmacokinetic studies suggested the variable safety and the potential efficacy of an antifungal prophylaxis with a single high dose of liposomal amphotericin B (L-AmB) in high-risk patients. An open-label, prospective study was conducted with 48 adults receiving induction chemotherapy for acute myeloid leukemia (AML). Patients received a single infusion of 15 mg/kg of body weight L-AmB and, eventually, a second dose after 15 days of persistent neutropenia. The primary objective was tolerability and safety. Efficacy was also evaluated as a secondary endpoint. A pharmacokinetic study was performed with 34 patients in order to evaluate any association of plasma L-AmB levels with toxicity and efficacy. Overall, only 6 patients (12.5%) reported Common Toxicity Criteria (CTC) grade 3 hypokalemia, which was corrected with potassium supplementation in all cases, and no patient developed clinically relevant nephrotoxicity. Mild infusion-related adverse events occurred after 6 of 53 (11.3%) total infusions, with permanent drug discontinuation in only one case. Proven invasive fungal disease (IFD) was diagnosed in 4 (8.3%) patients. The mean AmB plasma levels at 6 h, 24 h, and 7 days after L-AmB administration were 160, 49.5, and 1 mg/liter, respectively. The plasma AmB levels were higher than the mean values of the overall population in 3 patients who developed CTC grade 3 hypokalemia and did not significantly differ from the mean values of the overall population in 3 patients who developed IFD. Our experience demonstrates the feasibility and safety of a single 15-mg/kg L-AmB dose as antifungal prophylaxis in AML patients undergoing induction chemotherapy.

Mantle cell lymphoma (MCL) is an aggressive neoplasm with a short survival. Cases with leukaemic MCL and splenomegaly without adenopathies (non-nodal MCL) may have a more indolent course. To gain insights into the biological features underlying this presentation, we investigated the gene expression profile (GEP) and the IGHV mutational status in a cohort of leukaemic MCL cases. Comparison of MCL with other lymphoproliferative disorders (i.e. splenic marginal zone lymphoma, follicular lymphoma, chronic lymphocytic leukaemia) revealed a MCL signature enriched for the following gene categories: mitochondrion, oxidoreductase activity, response to stress, to DNA damage and TP53-pathway. Furthermore, GEP analysis revealed that non-nodal MCL cases were characterized by the down-modulation of the following gene categories: cell projection, actin cytoskeleton organization, cell adhesion (ITGAE, CELSR1, PCDH9) and tumour invasion/progression (PGF, ST14, ETS1, OCIAD1, EZR). Many down-modulated genes were related to the TP53-pathway and to DNA damage response. IGHV status proved unmutated in all nodal and mutated in all non-nodal MCL. Non-nodal leukaemic MCLs display a peculiar clinical presentation, with distinctive biological features, such as mutated IGHV and a transcriptional profile lacking tumour invasion properties, that might contribute to the absence of nodal involvement and to the less aggressive clinical course., (© 2011 Blackwell Publishing Ltd.)

Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. Gene-expression profiling in DLCBL has brought insight into the biological heterogeneity of the disease. Two major subgroups have been identified: germinal center B (GCB) cell and non-germinal center (non-GCB). The aim of this study was to define retrospectively by immunohistochemistry the bcell origin of 69 patients treated with R-CHOP14 and to evaluate if dose-dense therapy could improve their clinical outcome. According to immunohistochemistry analysis 28 patients were derived from germinal center and 41 from non-germinal center. After a median period of observation of 46 months (range 3-101 months) the overall survival (OS) was 75% and progression-free survival (PFS) was 53% and no differences were observed according to cell origin. In conclusion, we can point out that intensification could enhance the efficacy of the R-CHOP regimen and improve overall survival in patients with non germinal lymphoma.

In the last decades, the global epidemiological impact of invasive candidiasis (IC) in patients with hematologic malignancies (HM) and in hematopoietic stem cell transplant (HSCT) recipients has decreased and the incidence of invasive aspergillosis exceeded that of Candida infections. The use of prevention strategies, first of all antifungal prophylaxis with triazoles, contributed to the reduction of IC in these populations as demonstrated by several epidemiological studies. However, relatively little is known about the current epidemiological patterns of IC in HM and HSCT populations, because recent epidemiological data almost exclusively derive from retrospective experiences and few prospective data are available. Several prospective, controlled studies in the prophylaxis of invasive fungal diseases have been conducted in both the HM and HSCT setting. On the contrary, most of the prospective controlled trials that demonstrated the efficacy of the antifungal drugs echinocandins and voriconazole in the treatment of candidemia and invasive candidiasis mainly involved patients with underlying conditions other than HM or HSCT. For these reasons, international guidelines provided specific indications for the prophylaxis strategies in HM and HSCT patients, whereas the recommendations on therapy of documented Candida infections are based on the results observed in the general population and should be considered with caution.

Background: Third-generation regimens (MACOP-B [methotrexate/leucovorin (LV)/doxorubicin/cyclophosphamide/vincristine/ prednisone/bleomycin] or VACOP-B [etoposide/LV/doxorubicin/cyclophosphamide/vincristine/prednisone/bleomycin]) in combination with local radiation therapy seem to improve lymphoma-free survival of primary mediastinal large B-cell lymphoma (PMLBCL). Recently, the superiority of R-CHOP (rituximab plus cyclophosphamide/doxorubicin/vincristine/ prednisone) over CHOP-like regimens has been demonstrated in elderly and younger patients with low-risk diffuse large B-cell lymphoma., Patients and Methods: Retrospectively, between February 2002 and July 2006, 45 previously untreated patients with PMLBCL were treated with a combination of a third-generation chemotherapy regimen (MACOP-B or VACOP-B), concurrent rituximab, and mediastinal radiation therapy., Results: Twenty-six (62%) patients achieved a complete response (CR), and 15 (36%) obtained a partial response after MACOP-B/VACOP-B plus rituximab. After radiation therapy, the CR rate was 80%. At a median follow-up of 28 months, among the 34 patients who obtained a CR, 3 relapsed after 16, 19, and 22 months, respectively. Projected overall survival was 80% at 5 years; the relapse-free survival (RFS) curve of the 34 patients who achieved CR was 88% at 5 years., Conclusion: In this retrospective study, in patients with PMLBCL, combined-modality treatment using the MACOP-B/VACOP-B regimen plus rituximab induces a high remission rate, with patients having a > 80% chance of surviving relapse free at 5 years. In comparison with historical data on MACOP-B/VACOP-B without rituximab, there are no statistically significant differences in terms of CR and RFS rates.

Purpose: To report the clinical findings and long-term results of front-line, third-generation MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin) chemotherapy and mediastinal involved-field radiotherapy (IFRT) in 85 consecutive, previously untreated patients with primary mediastinal large B cell lymphoma (PMLBCL) diagnosed and managed at a single institution., Methods and Materials: Between 1991 and April 2004, 92 consecutive, untreated patients with PMLBCL were treated at our institution. The median age was 33 years (range, 15-61 years), 46 patients (50%) showed a mediastinal syndrome at onset; 52 patients (57%) showed a low/low-intermediate (0 to 1) and 40 patients (43%) an intermediate-high/high (2 to 3) International Prognostic Index (IPI) score. Eighty-five patients were treated with standard chemotherapy (MACOP-B), and 80 underwent mediastinal IFRT at a dose of 30-36 Gy., Results: After a MACOP-B regimen, the overall response rate was 87% and the partial response rate 9%. After chemotherapy, (67)Ga scintigraphy/positron emission tomography results were positive in 43 of 52 patients (83%), whereas after IFRT 11 of 52 patients (21%) remained positive (p < 0.0001). After a median follow-up of 81 months (range, 2-196 months), progression or relapse was observed in 15 of 84 patients (18%). The projected 5-year overall survival and progression-free survival rates were 87% and 81%, respectively. The 5-year overall survival and progression-free survival rates were better for patients with an IPI of 0 to 1 than for those with an IPI of 2 to 3 (96% vs. 73% [p = 0.002] and 90% vs. 67% [p = 0.007], respectively)., Conclusions: Combined-modality treatment with intensive chemotherapy plus mediastinal IFRT induces high response and lymphoma-free survival rates. Involved-field RT plays an important role in inducing negative results on (67)Ga scintigraphy/positron emission tomography in patients responsive to chemotherapy.

Philadelphia positive (Ph+) chronic myeloid leukaemia (CML) presenting synchronously or following non-Hodgkin lymphoma (NHL) has only rarely been reported. Herein, we refer on a case of Ph+ CML occurring after a breast cancer and a NHL with multiple relapses. After obtaining complete cytogenetic remission with imatinib, the patient presented a new NHL relapse, that was treated with rituximab concomitantly to imatinib. Therapy was well tolerated and the patient is presently alive in complete remission of either NHL and CML. We also reviewed the literature relating the uncommon association of these two unrelated diseases.

Epigenetic alterations of chromatin due to aberrant histone deacetylase (HDAC) activity and transcriptional silencing of all-trans retinoic acid (ATRA) pathway are events linked to the pathogenesis of acute myeloid leukemia (AML) that can be targeted by specific treatments. A pilot study was carried out in eight refractory or high-risk AML patients not eligible for intensive therapy to assess the biological and therapeutic activities of the HDAC inhibitor valproic acid (VPA) used to remodel chromatin, followed by the addition of ATRA, to activate gene transcription and differentiation in leukemic cells. Hyperacetylation of histones H3 and H4 was detectable at therapeutic VPA serum levels (>or=50 microg/mL) in blood mononuclear cells from seven of eight patients. This correlated with myelomonocytic differentiation of leukemic cells as revealed by morphologic, cytochemical, immunophenotypic, and gene expression analyses. Differentiation of the leukemic clone was proven by fluorescence in situ hybridization analysis showing the cytogenetic lesion +8 or 7q- in differentiating cells. Hematologic improvement, according to established criteria for myelodysplastic syndromes, was observed in two cases. Stable disease and disease progression were observed in five and one cases, respectively. In conclusion, VPA-ATRA treatment is well tolerated and induces phenotypic changes of AML blasts through chromatin remodeling. Further studies are needed to evaluate whether VPA-ATRA treatment by reprogramming differentiation of the leukemic clone might improve the response to chemotherapy in leukemia patients.

To verify the potential clinical and prognostic value of BCR/ABL isoforms, we analyzed 101 consecutive adult patients with Philadelphia chromosome-positive acute lymphoblastic leukemia enrolled in the GIMEMA 0496 trial between October 1996 and December 1999. A p190 or p210 with or without p190 BCR/ABL transcript was documented in 59 (58.5%) and 42 cases (41.5%), respectively. At diagnosis, a white cell count <16 x 10(9)/L and a higher level of CD34 and CD33 expression were associated with the p190 BCR/ABL transcript (p<0.05, p=0.009 and p=0.03, respectively). A complete remission was achieved in 62/92 (67.4%) patients, while 16/92 (17.4%) were resistant and 14/92 (15.2%) died of therapy-related complications. Fifty-two patients underwent intensive re-induction treatment, which was followed by stem cell transplant consolidation in the 36 in persistent complete remission (allogeneic = 20 patients; autologous = 16 patients). Response rates to induction therapies were similar in the two BCR/ABL isoform groups. By contrast, the p190 emerged as the only independent prognostic factor favorably affecting the 5-year overall survival and disease-free survival rates (p=0.008 and p=0.02, respectively).

The role of surgery in the treatment of primary gastric lymphoma has been recently re-evaluated. We report the results of a series of 37 operated patients for primary gastric lymphoma (PGL). All patients underwent gastrectomy with D2 lymphadenectony and bilateral liver biopsies. Postoperative histopathological classification was compared to preoperative staging data. No mortality and low morbidity were observed in this series of patients. We found a high incidence of mixed grading of tumors and a relatively high incidence of lymph node metastases in low grade lymphoma. Relying on preoperative biopsies and imaging techniques could lead to preoperative staging inaccuracy and therefore to inappropriate treatment planning. For these reasons we advocate systematic primary surgery in PGL. Surgery could be useful for staging purposes and seems to be curative in stage IE.

The anti-CD33 antibody calicheamicinconjugate gemtuzumab ozogamicin (GO) was used to treat 16 patients with acute promyelocytic leukemia (APL) who had relapsed at the molecular level. Of these patients, 8 were experiencing a first, 5 a second, 2 a third, and 1 a fourth relapse. GO was administered at 6 mg/m2 for 2 doses, and patients achieving a new molecular remission (MR) (ie, negativity of the reverse transcriptase-polymerase chain reaction [RT-PCR] test for PML/RARalpha) received a third dose. MR was obtained in 9 (91%) of 11 patients tested after 2 doses and in 13 (100%) of 13 patients tested after the third dose. Of the 3 remaining patients, 1 achieved MR after one GO administration and received no further therapy owing to hepatic toxicity, and 2 showed disease progression during treatment. Quantitative RT-PCR studies showed that responding patients experienced a dramatic decline (at least 2 logs) of the PML/RARalpha transcript after the first GO dose. Of 14 responders, 7 remained in sustained MR for a median of 15 months (range, 7-31 months) while 7 experienced relapse at 3 to 15 months. GO was administered again in 2 patients with relapse, and both obtained a new MR. These data indicate that GO is highly effective as a single treatment for patients with molecularly relapsed APL including those with very advanced disease.

In this minireview the authors examine and discuss the radioprotective compounds and the new combination therapies for the prophylaxis of radiation-induced emesis. Radiation-induced emesis is an important secondary effect of this anticancer treatment and it represents one of the causes of therapy interruption and decay of life quality before the introduction of optimal control of radiation-induced emesis with new antiemetic drugs which ensure the continuance of radiotherapy and avoid time breaks, that could negatively influence the efficacy of anticancer treatment. The incidence, the severity or the latency of radiotherapy-induced nausea and vomiting are correlated both with the treatment features (fractions, total dose, irradiation site) and with the main clinical characteristics of the patients. In contrast to the very extensive literature on the prevention of chemotherapy-induced emesis, relatively few studies about the prevention of nausea and vomiting in patients submitted to radiotherapy have been published. Among antiemetic drugs for the prevention of emesis, benzamides and in particular metoclopramide, are widely used in clinical practice. The introduction of selective 5-HT3 antagonists in clinical practice produced an important improvement in control of chemotherapy induced emesis, but few published studies were aimed at evaluating the efficacy of these drugs in the prophylaxis of nausea and vomiting due to radiation exposure. We herewith present a brief summary of Clinical practice guidelines for the use of antiemetics in anticancer therapy recently published by ASCO (American Society of Clinical Oncology).

More than 550,000 American people died for cancer only in 1998 and more than third of them were over 65 years of age. According to recent data in next decade more than 70% of all the deaths for tumour will be verified in the population over 65 years. The cancers mostly frequently associated with the deaths in the elderly population are the tumour of the lung, colon, prostate and breast. Therefore the geriatrics oncology is progressively assuming a central and essential role within the medical oncology. One of the aspects of great interest in the treatment of the cancers of the elderly patient (> 65 years) is the study about some pharmacokinetic modifications of the antitumour medicines in such band of age, and the study about some pattern of toxicity characteristics in the elderly patients. In this ambit there are a few studies in literature devoted specifically to such aspect. This study represents an attempt of revision of the literature finalized to analyse the toxicological and pharmacokinetic characteristics of the principal chemotherapeutic agents used in the therapy of elderly patients affected with cancer. In the last part of the review we have tried to synthesize the state of the art of the achieved results about the medicines that have shown a better therapeutic index and a better impact on the clinical benefit in such population of patients.

A case of a 32-years old man with a long lasting history of inflammatory bowel disease (IBD) is described. He was treated in the past with adequate medical therapy with considerable improvement of the symptoms. However, after the resolution of the last episode of abdominal pain and diarrhoea, because of multiple protruding masses and sub-stenotic regions found during a colonoscopy, the patient underwent a right enlarged hemicolectomy with jejunal resection. During the surgical procedure 16 enlarged lymphnodes were removed. The histological examination of the surgical specimen showed the presence of numerous Reed-Sternberg cells, compatible with a diagnosis of Hodgkin's disease (HD). None of the removed lymphnodes showed the presence of tumor cells, and in addition the systemic staging procedure was negative. After staging, the ABVD regimen was started, achieving a complete clinical and pathological response. This is a rare case of primary extranodal HD localized to the colon, in a patient with a long standing history of IBD, who showed an optimal response to chemotherapy. The case and the differential diagnosis with other pathological entities of the bowel is discussed.
