Abstract
For treatment of several malignancies, transplantation of allogeneic haematopoietic stem cells (HSCT) derived from bone marrow or peripheral blood has been used as a therapeutic procedure for decades. In the past, HSCT has been suggested as a treatment option for infection with the human immunodeficiency virus type 1 (HIV-1), but these attempts were mostly unsuccessful. Today, after the introduction of an active anti-retroviral therapy, the lifetime expectancy of HIV-infected patients has improved substantially, but nevertheless the incidence rate of malignancies in these patients has increased considerably. Therefore, it can be assumed that there will be a rising necessity for HIV-1-infected patients with malignancies for allogeneic HSCT. At the same time, there is increasing interest in treatment methods which might target the HIV-1 reservoir more effectively, and the question has been raised as to whether allogeneic HSCT could be linked to such strategies. In this paper the data of more than 25 years experience with allogeneic HSCT in patients with HIV-1 are reviewed and analysed.

Abstract
The advent of Highly Active Antiretroviral Therapy (HAART) has radically changed incidence characteristics and prognosis of HIV-positive patients affected by lymphomas. At this time there is consensus in the literature that, in first line, HIV-positive patients should always be treated with curative intent preferentially following the same approach used in the HIV-negative counterpart. On the contrary, an approach of salvage therapy in HIV-positive lymphomas is still a matter of debate given that for a wide range of relapsed or resistant HIV-negative Hodgkin's disease (HD) and non-Hodgkin lymphoma (NHL) patients, autologous peripheral or allogeneic stem cell transplantation are among the established options. In the pre-HAART era, therapeutic options derived from pioneering experiences gave only anecdotal success, either when transplantation was used to cure lymphomas or to improve HIV infection itself. Concerns relating to the entity, quality, and kinetics of early and late immune reconstitutions and the possible worsening of underlying viroimmunological conditions were additional obstacles. Currently, around 100 relapsed or resistant HIV-positive lymphomas have been treated with an autologous peripheral stem cell transplantation (APSCT) in the HAART era. Published data compared favorably with any previous salvage attempt showing a percentage of complete remission ranging from 48% to 90%, and overall survival ranging from 36% to 85% at median follow-up approaching 3 years. However, experiences are still limited and have given somewhat confounding indications, especially concerning timing and patients' selection for APSCT and feasibility and outcome for allogeneic stem cell transplant. Moreover, little data exist on the kinetics of immunological reconstitution after APSCT or relevant to the outcome of HIV infection. The aim of this review is to discuss current knowledge of the role of allogeneic and autologous stem cell transplantation as a modality in the cure of HIV and hemopoietic cancer patients. Several topics dealing with practical aspects concerning the management of APSCT in HIV-positive patients, including patient selection, timing of transplant, conditioning regimen, and relapse or nonrelapse mortality, are discussed. Data relating to the effects of mobilization and transplantation on virological parameters and pre- and posttransplant immune reconstitution are reviewed. Finally, in this review, we examine several ethical and legal issues relative to banking infected or potentially infected peripheral blood stem cells and we describe our experience and strategies to protect positive and negative donors/recipients and the health of caretakers.

Abstract
The kinetics and predictive value of HIV-1 DNA (HIV DNA) levels in relapsed or refractory HIV lymphoma patients, treated with high-dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT), were investigated. HIV DNA was measured by real-time PCR in the peripheral blood mononuclear cells (PBMCs) of 22 patients observed for a median follow-up of 31.0 months. At baseline, HIV DNA was found to be correlated with HIV-1 RNA (HIV RNA) (r = 0.56), but not with CD4(+) counts (r = -0.10). HIV RNA load was under control for the entire follow-up, while HIV DNA levels were almost always detectable (baseline levels vs. 1 year from ASCT levels, p > 0.05). Baseline HIV DNA levels were significantly different between alive and deceased patients (p = 0.03), and the overall survival (OS) analysis showed that for patients with higher HIV DNA levels at baseline there was a higher and nearly significant risk of death if compared to patients with lower levels (HR, 8.33, 95% CI, 0.99-70.06, p = 0.05). Our study demonstrated that high HIV DNA levels at baseline could predict overall survival after ASCT in one of the largest cohorts of HIV lymphoma patients treated with salvage therapy.

Abstract
PURPOSE OF REVIEW Morbidity and mortality related to malignancy are increasing in HIV-infected patients. We aim at reviewing the literature on recent changes in the incidence of AIDS-defining and non-AIDS-defining malignancies and the specific characteristics of the main cancers emerging in HIV-infected patients. RECENT FINDINGS Currently, malignancies are the most frequent underlying cause of death (around one-third) of HIV-infected patients. Since the introduction of combination antiretroviral therapy, the incidence of Kaposi's sarcoma and cerebral lymphoma (among AIDS-defining cancers) decreased in parallel with AIDS-defining infections, whereas the incidence of systemic non-Hodgkin's lymphoma and cervical cancer decreased less than others and remains higher in HIV-infected patients than in the general population. The most recent and large studies have also shown a 1.7-3-fold higher risk of developing non-AIDS malignancies in HIV-infected patients as compared with the general population without a significant impact of combination antiretroviral therapy on these trends. These malignancies include Hodgkin's disease, lung, anal, head and neck cancers, hemopathies, and conjunctival cancers. In addition, the poorer prognosis reported in HIV-infected patients affected by malignancies might be interpreted as a consequence of late screening or immunosuppression. SUMMARY Prevention and screening management procedures need to be assessed on the basis of specific evidence-based studies in the HIV-infected population. Interventions, known to be efficacious in other populations, should systematically be used or adapted if necessary (alcohol and tobacco cessation programs and viral coinfection management). The respective role of HIV itself, immunosuppression, and antiretrovirals as pro-oncogenic factors need to be further examined.
