Abstract
The association of human immunodeficiency virus (HIV) and aggressive lymphomas was first reported in 1982. Before the development of effective HIV antiviral therapy, the incidence and the mortality of these lymphomas was high, with patients frequently succumbing to the disease. More lately, the combination of cART with chemoimmunotherapy significantly improved the survival outcome of the HIV-lymphomas. In this review, we discuss on describing the incidence of HIV-associated lymphomas, their clinical features, and the latest advances in the management of the various lymphoma subtypes.

Gijs PJ, Clerc O. Long-term remission of AIDS-related primary central nervous system lymphoma in a patient under antiretroviral therapy: a case report and review of the literature. AIDS Res Ther 2021; 18:76. [PMID: 34666791 PMCID: PMC8527804 DOI: 10.1186/s12981-021-00403-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Accepted: 10/07/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND AIDS-related primary central nervous system lymphoma (AR-PCNSL) is an AIDS-defining disease that usually occurs when the CD4 count is less than 50 cells/μl. The frequency of the disease has substantially decreased in the era of highly active antiretroviral therapy (HAART). Prognosis is poor with rapid progression leading to death within 2-3 months if left untreated. CASE DESCRIPTION A 65 years old male presented to medical attention with gait disturbance, weight loss and slight left-sided hemiparesis. Human immunodeficiency virus infection was diagnosed with an initial CD4 count of 116 cells/µl and a viral load of 260,000 copies/ml. Magnetic resonance imaging of the brain revealed three brain lesions involving the right frontal lobe and the left parietal lobe, which on biopsy led to a diagnosis of AR-PCNSL. HAART was initiated with whole-brain radiotherapy (WBRT), and the patient declined systemic chemotherapy. Due to poor performance status, he was transferred to palliative care. Under HAART, he slowly recovered with normalization of CD4 count and undetectable viral load. Medical imaging showed complete remission (CR) of the brain lesions. At 3-year follow-up, the patient remains in CR, but presented mild neurocognitive dysfunction possibly secondary to WBRT. CONCLUSION Nowadays, treatment paradigm parallels that of primary central nervous system lymphoma in the immunocompetent population based on systemic chemotherapy (primarily high-dose intravenous methotrexate and steroids) in association with HAART. The role of WBRT is questionable because of late neurotoxic effects.

Abstract
Purpose: To describe the epidemiology, clinical characteristics, diagnosis and treatment of human immunodeficiency virus (HIV)-related primary vitreoretinal lymphoma (PVRL).Methods: Narrative literature review.Results: HIV-related PVRL occurs in persons who are relatively young and generally have very low CD4+ T-cell counts. Vitritis with subretinal or sub-retinal pigment epithelial infiltrates is typical. Vitreous cytology remains the gold standard for diagnosis, supplemented by flow cytometry and genetic analyses of tumor cells, and measurement of aqueous or vitreous interleukin-10 levels. Concurrent brain involvement also may establish the diagnosis. Treatment includes antiretroviral therapy (ART), systemic chemotherapy (usually methotrexate-based) and local ocular treatment (intravitreal methotrexate, intravitreal rituximab, external beam radiotherapy). Systemic chemotherapy is of uncertain value for PVRL without other central nervous system involvement. Prognosis is poor, but has improved significantly compared to the pre-ART era.Conclusions: Ophthalmologists should consider the diagnosis of PVRL in HIV-positive individuals who present with intermediate or posterior uveitis.

Abstract
Radiation therapy plays a significant role in the palliation of symptoms of patients with malignant disease. This article looks at the scientific and clinical rationales for its use and discusses some of the current controversies in palliative radiotherapy. The utility of radiation therapy is discussed and potential side effects are described. Radiation oncologists are important members of the multidisciplinary team providing palliative care. Their involvement in the care of patients with advanced or metastatic malignant disease allows patients to benefit from a modality of treatment which can be both effective and minimally inconvenient when used appropriately.

Abstract
Patients infected with human immunodeficiency virus (HIV) are at increased risk for developing both non-Hodgkin’s lymphoma (NHL) and Hodgkin’s lymphoma (HL). Even if this risk has decreased for NHL after the introduction of combination antiretroviral therapy (cART), they remain the most common acquired immune deficiency syndrome (AIDS)-related cancer in the developed world. They are almost always of B-cell origin, and some specific lymphoma types are more common than others. Some of these lymphoma types can occur in both HIV-uninfected and infected patients, while others preferentially develop in the context of AIDS. HIV-associated lymphoma differs from lymphoma in the HIV negative population in that they more often present with advanced disease, systemic symptoms, and extranodal involvement and are frequently associated with oncogenic viruses (Epstein-Barr virus and/or human herpesvirus-8). Before the introduction of cART, most of these patients could not tolerate the treatment strategies routinely employed in the HIV-negative population. The widespread use of cART has allowed for the delivery of full-dose and dose-intensive chemotherapy regimens with improved outcomes that nowadays can be compared to those seen in non-HIV infected patients. However, a great deal of attention should be paid to opportunistic infections and other infectious complications, cART-chemotherapy interactions, and potential cumulative toxicity. In the context of relatively sparse prospective and randomized trials, the optimal treatment of AIDS-related lymphomas remains a challenge, particularly in patients with severe immunosuppression. This paper will address epidemiology, pathogenesis, and therapeutic strategies in HIV-associated NHL and HL.

Abstract
The incidence of non-Hodgkin's lymphoma and Hodgkin's lymphoma is higher in patients with HIV infection than in the general population. Following the introduction of combination antiretroviral therapy (cART), the prognostic significance of HIV-related variables has decreased, and lymphoma-related factors have become more pronounced. Currently, treatments for lymphomas in HIV-infected patients do not differ from those used in the general population. However, differentiating characteristics of seropositive patients, such as the need for cART and specific prophylaxis and treatment of certain opportunistic infections, should be considered. This document updates recommendations on the diagnosis and treatment of lymphomas in HIV infected patients published by GESIDA/PETHEMA in 2008.

Abstract
Primary CNS lymphoma (PCNSL) has been designated an acquired immune deficiency syndrome (AIDS)-defining disease since 1983 and accounts for up to 15% of non-Hodgkin lymphomas in human immunodeficiency virus (HIV) patients. The majority of HIV patients are Epstein-Barr virus (EBV)-related. The most likely etiology is ineffective immunoregulation of EBV, inducing oncogenic protein expression, and subsequent loss of apoptosis and increased proliferation of lymphocytes. PCNSL generally presents with supratentorial, single or multiple, contrast-enhancing lesions. Neurologic symptoms can be headache, cognitive function disorders, focal neurologic, deficit and epilepsy. Differential diagnosis includes other oncologic or infectious causes, with cerebral toxoplasmosis being the most important. Magnetic resonance imaging characteristics, activity on 201thallium single-photon emission computed tomography, presence of EBV DNA in the cerebrospinal fluid, and toxoplasmosis serology can make either PCNSL or cerebral toxoplasmosis more or less likely. However, definitive diagnosis of PCNSL relies on histopathologic confirmation. First-choice treatment is combination antiretroviral therapy in combination with high-dose methotrexate(-based) chemotherapy in patients in whom this is feasible. Combination antiretroviral therapy combined with whole-brain radiotherapy may be an alternative. Treatment of EBV with antiviral agents such as ganciclovir or zidovudine may be beneficial, but this needs further study. Prognosis of HIV-related PCNSL is poor, with median survival varying from 2 to 4 months, but patients treated with chemotherapy do better (median survival 1.5 years).

Role of Autophagy in HIV-1 Matrix Protein p17-Driven Lymphangiogenesis. J Virol 2017; 91:JVI.00801-17. [PMID: 28592537 DOI: 10.1128/jvi.00801-17] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Accepted: 05/29/2017] [Indexed: 12/18/2022] Open
Abstract
AIDS-related lymphomas (ARLs) are expected to increase in the future since combined antiretroviral therapy (cART) enhances the life expectancy of HIV-1-infected (HIV+) patients but does not affect the occurrence of ARLs to the same extent as that of other tumors. Lymphangiogenesis is essential in supporting growth and metastatic spreading of ARLs. HIV-1 does not infect the neoplastic B cells, but HIV-1 proteins have been hypothesized to play a key role in sustaining a prolymphangiogenic microenvironment in lymphoid organs. The HIV-1 matrix protein p17 is detected in blood and accumulates in the germinal centers of lymph nodes of HIV+ patients under successful cART. The viral protein displays potent lymphangiogenic activity in vitro and in vivo This is, at least in part, mediated by the secretion of the lymphangiogenic factor endothelin-1, suggesting that activation of a secretory pathway sustains the lymphangiogenic activity of p17. Here, we show that the p17 lymphangiogenic activity occurs on human lymph node-derived lymphatic endothelial cells (LN-LECs) under stress conditions only and relies entirely on activation of an autophagy-based pathway. In fact, induction of autophagy by p17 promotes lymphangiogenesis, whereas pharmacological and genetic inhibition of autophagy inhibits p17-triggered lymphangiogenesis. Similarly, the vasculogenic activity of p17 was totally inhibited in autophagy-incompetent mice. Our findings reveal a previously unrecognized role of autophagy in lymphangiogenesis and open the way to identify novel treatment strategies aimed at inhibiting aberrant tumor-driven lymphangiogenesis in HIV+ patients.IMPORTANCE AIDS-related lymphomas (ARLs) are the most common malignancies in HIV-1-infected (HIV+) patients after the introduction of combined antiretroviral therapy (cART). Lymphangiogenesis is of critical importance in sustaining growth and metastasis of ARLs. Indeed, enhanced lymphangiogenesis occurs in the lymph nodes of HIV+ patients under successful cART. The HIV-1 matrix protein p17 is detected in blood and accumulates in the lymph node germinal centers even in the absence of virus replication. Several findings suggest a key role for p17 as a microenvironmental factor capable of promoting lymphangiogenesis. Here, we show that p17 promotes lymphangiogenesis of human lymph node-derived lymphatic endothelial cells (LN-LECs). The lymphangiogenic activity of p17 is sustained by an autophagy-based pathway that enables LN-LECs to release prolymphangiogenic factors into the extracellular microenvironment. Our findings indicate that specific targeting of autophagy may provide an important new tool for treating ARLs.

Abstract
OBJECTIVE To assess the characteristics and outcomes of patients with AIDS-related primary CNS lymphoma (AR-PCNSL) in the combined antiretroviral therapy (cART) era systematically treated with high-dose methotrexate (HD-MTX). METHODS We retrospectively analyzed (intention-to-treat analysis) 51 consecutive patients with AR-PCNSL (median age 39 years) who were diagnosed from 1996 to 2014 and treated with a median of 6 (range 1-15) infusions of HD-MTX (3 g/m2) combined with cART. RESULTS Median all-patients' and survivors' follow-up lasted 23 (range 0-186) and 76 (range 23-186) months, respectively. At PCNSL diagnosis, 83% of the patients were on cART, median plasma HIV load was 175,600 copies/mL, and median CD4+ T-cell count was 24/μL. Median Eastern Cooperative Oncology Group performance status was 2 (range 1-4). Median overall survival (OS) was 5.7 years, with 5- and 10-year rates of 48% and 41%. Median time to progression was not reached (69% at 10 months). PCNSL was the direct cause of 14 deaths, all observed within the 10 months after its diagnosis: 6 patients died before HD-MTX could be administered, 4 had refractory disease, and 4 relapsed. Multivariate analyses retained time interval between AIDS diagnosis and PCNSL diagnosis, age at AR-PCNSL diagnosis, and deep brain structure involvement as independent OS-predictive factors. To restore effective immune function, cART tailored to HIV genotypes was started and combined with HD-MTX; no interactions and no immune reconstitution inflammatory syndrome occurred. No patient died of acute treatment-related toxicity, and 21 of 51 (41%) patients experienced grade 3/4 toxicity. CONCLUSIONS Combined short-term HD-MTX monochemotherapy and optimal cART simply and effectively treat AR-PCNSL, achieving long-term survival with few relapses. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence that short-term HD-MTX monochemotherapy improves long-term survival of patients with AIDS with primary CNS lymphoma receiving cARTs.

Abstract
BACKGROUND We performed a systematic review and meta-analysis to assess the roles of SPECT, PET, and MRS in distinguishing primary central nervous system lymphoma (PCNSL) from other focal brain lesions (FBLs) in human immunodeficiency virus (HIV)-infected patients. METHODS PubMed, Scopus, and Medline were systematically searched for eligible studies from 1980 to 2016. Two authors extracted characteristics of patients and their lesions using predefined criteria. RESULTS Eighteen studies on SPECT containing 667 patients, 6 studies on PET containing 108 patients, and 3 studies on MRS containing 96 patients were included. SPECT had a pooled sensitivity of 0.92 (95% CI: 0.85-0.96) and specificity of 0.84 (95% CI: 0.74-0.90) in differentiating PCNSL from other FBLs. For the 6 studies that used only pathology and/or serology as the gold standard, the pooled sensitivity was 0.85 (95% CI: 0.72-0.97) and the pooled specificity was 0.73 (95% CI: 0.54-0.92). CONCLUSION SPECT has good diagnostic accuracy for discriminating PCNSL from other FBL-causing disorders in HIV patients. However, the actual sensitivity and specificity of SPECT may be lower than expected if only pathology and/or serology was used as the gold standard. PET may be superior but has less supporting clinical data and is more expensive.

Abstract
Il linfoma primitivo cerebrale (LPC) è la più comune delle neoplasie opportunistiche del SNC in pazienti AIDS, seguito dal linfoma di Kaposi e dai gliomi, e spesso rappresenta la patologia rivelatrice della condizione di immunodeficienza acquisita. L'incidenza dei LPC è in costante aumento nelle ultime due decadi. Attualmente rappresentano il 6,6–15,4% di tutti i tumori cerebrali primitivi contro il 3,3% registrato prima del 1978. Nei pazienti AIDS, ha una frequenza compresa fra il 3% ed il 10%. Si tratta, peraltro, di una patologia ancora relativamente rara costituendo solo lo 0,7–0,9% di tutti i linfomi. I LPC si localizzano in prevalenza in regione sopratentoriale (90%) specialmente nella sostanza grigia periventricolare e nella sostanza bianca; la localizzazione in fossa cranica posteriore è stimata intorno al 10%. Nel LPC l'interessamento leptomeningeo non è comune riscontrandosi in circa il 12% dei casi; più raro il coinvolgimento durale, rarissimo (circa 1%) il coinvolgimento del midollo spinale. Viceversa il linfoma secondario tende ad invadere la dura madre e le leptomeningi. Il LPC in corso di AIDS si manifesta in forma multifocale fra il 50 ed il 75%. Dal 1991 è stata documentata una quasi costante associazione del virus di Ebstein-Barr (EBV) con il LPC il che ha indotto a considerare la possibilità di usare l'EBV come un marker diagnostico di tale patologia. La costante presenza del EBV nel LPC in immunodepressi è in contrasto con quanto visto negli immunocompetenti ove l'associazione è modesta. Ad una valutazione macroscopica il LPC si manifesta come massa nodulare con consistenza molto variabile da friabile a solida e superficie granulare. La lesione è frequentemente circondata da edema, comunemente diffonde alla leptomeninge e alle regioni subpiali. È multifocale nel 11–50% dei pazienti immunocompetenti e nel 41–81% dei pazienti AIDS nei quali peraltro l'incidenza di multifocalità può raggiungere il 100%. All'analisi istologica il LPC mostra strati uniformi di cellule neoplastiche, strettamente stipate; il processo di infiltrazione si diffonde ben oltre i margini macroscopici della lesione. Necrosi ed emorragie sono molto più frequenti nei pazienti immunocompromessi. Neuroradiologicamente le lesioni risultano tipicamente iperdense alla TC e questo aspetto è attribuito ad un alto rapporto nucleo-citoplasma ed ad un elevata cellularità fittamente stipata. Dopo mdc praticamente tutti i LPC mostrano impregnazione la cui intensità è peraltro variabile e talora così debole e indefinita da non essere apprezzata se non utilizzando appropriate finestre. In RM nelle immagini T1 la lesione è tipicamente da ipo- ad isointensa relativamente alla sostanza grigia e produce un effetto massa modesto rispetto alle sue dimensioni. Nei primi riferimenti della letteratura tali lesioni erano descritte quasi uniformemente iperintense in T2. Più recentemente, e probabilmente in rapporto ad un affinamento del software che ha consentito una maggiore evidenza di fini dettagli, le lesioni si documentano prevalentemente iso-ipointense alla sostanza grigia in T2, aspetto che, come alla TC, riflette l'alto rapporto nucleo- citoplasma e l'elevata cellularità fittamente stipata. Nella popolazione non AIDS il LPC mostra quasi costantemente alla RM un impregnazione dopo mdc che risulta omogeneo nei 2/3 dei casi. Nella popolazione AIDS il LPC mostra impregnazione nel 100% dei casi che risulta disomogeneo nel 54% dei casi, con un pattern anulare nel 46% ed uno irregolare nell '8%. Uno degli aspetti caratteristici del LPC è la tendenza a diffondere lungo l'ependima, le meningi o entrambe. Questa dtffusione è documentata in percentuali variabili che raggiungono il 75% e si attestano al 28% per la contiguità con la superficie ependimale e 1′8% per la contiguità con la meninge.

Abstract
Objective: To determine the diagnostic efficiency of thallium-201 single photon emission computed tomography (SPECT) and Epstein-Barr virus (EBV) polymerase chain reaction (PCR) in the differentiation of primary central nervous system lymphoma (PCNSL) from other central nervous system processes in patients with HIV/AIDS. Design/Methods: Over 10 years, 68 thallium-201 SPECT scans were performed on neurologically symptomatic HIV+ patients with focal lesions on CT or MRI at the Johns Hopkins Hospital. Diagnoses were then established by either autopsy, biopsy, or clinical response to anti-toxoplasmosis therapy. Patients were categorized prior to a prospective clinical reading of the SPECT scans by nuclear medicine physicians. Results: In our patient sample overall, the diagnostic efficiency of thallium-201 SPECT was 79%. The diagnostic accuracy of EBV PCR testing alone in a subset of 22 patients in our study that had CSF analyzed was 73%. However, when both positive EBV PCR and positive thallium-201 SPECT results were used together, the diagnostic accuracy improved to 100% based on a sample of 13 patients where EBV PCR and SPECT imaging results were concordant. Conclusion: Thallium-201 SPECT has a relatively high positive predictive value with regards to the diagnosis of PCNSL, which suggests that patients with positive results could undergo empiric radiation treatment without resorting to brain biopsy. However, the predictive value can be increased by testing for CSF EBV using PCR. Alternatively, if CSF cannot be safely obtained because of mass effect, we believe that these data still suggest that empiric radiation treatment should be considered when discussing treatment options with patients with a positive thallium-201 SPECT.

Abstract
BACKGROUND The authors present a retrospective analysis of 45 patients who underwent treatment of CNS lymphoma (both primary and secondary) at a single institution between 2005 and 2012. METHODS This study involves 21 female and 24 male patients with a mean age of 59.2 years. All medical records and pathology reports were reviewed for each patient. Univariate and multivariate analyses of overall survival were performed. RESULTS Presentation with altered mental status was a significant risk factor for worse overall survival. An HIV infection, deep lesion location, and age over 60 did not impact survival. A survival benefit was demonstrated with the use of systemic therapy, specifically rituximab, and radiation. The CNS Lymphoma Score was derived from this cohort, which proved a powerful predictive tool for overall survival. The surgical complication rate in this series was 17.8 %. CONCLUSIONS This study highlights the prognostic importance of presenting mental status on outcomes in CNS lymphoma and demonstrates a summative benefit of rituximab and whole brain radiation therapy. Considering these factors together provides an easily applicable and meaningful stratification for this patient population. The surgical complication rate in this patient population is not negligible. The high percentage of wound-related surgical complications suggests the need for a waiting period between surgery and initiation of chemotherapy to allow for wound healing.

Abstract
OBJECTIVE AIDS-related lymphomas are high grade and aggressively metastatic with poor prognosis. Lymphangiogenesis is essential in supporting proliferation and survival of lymphoma, as well as tumor dissemination. Data suggest that aberrant lymphangiogenesis relies on action of HIV-1 proteins rather than on a direct effect of the virus itself. HIV-1 matrix protein p17 was found to accumulate and persist in lymph nodes of patients even under highly active antiretroviral therapy. Because p17 was recently found to exert a potent proangiogenic activity by interacting with chemokine (C-X-C motif) receptors 1 and 2, we tested the prolymphangiogenic activity of the viral protein. APPROACH AND RESULTS Human primary lymph node-derived lymphatic endothelial cells were used to perform capillary-like structure formation, wound healing, spheroids, and Western blot assays after stimulation with or without p17. Here, we show that p17 promotes lymphangiogenesis by binding to chemokine (C-X-C motif) receptor-1 and chemokine (C-X-C motif) receptor-2 expressed on lymph node-derived lymphatic endothelial cells and activating the Akt/extracellular signal-regulated kinase signaling pathway. In particular, it was found to induce capillary-like structure formation, sprout formation from spheroids, and increase lymph node-derived lymphatic endothelial cells motility. The p17 lymphangiogenic activity was, in part, sustained by activation of the endothelin-1/endothelin receptor B axis. A Matrigel plug assay showed that p17 was able to promote the outgrowth of lymphatic vessels in vivo, demonstrating that p17 directly regulates lymphatic vessel formation. CONCLUSIONS Our results suggest that p17 may generate a prolymphangiogenic microenvironment and plays a role in predisposing the lymph node to lymphoma growth and metastasis. This finding offers new opportunities to identify treatment strategies in combating AIDS-related lymphomas.

Abstract
OBJECTIVE AIDS-related primary central nervous system lymphoma (AR-PCNSL) has a poor prognosis. Improved understanding of specific patient, infectious, diagnostic, and treatment-related factors that affect overall survival (OS) is required to improve outcomes. DESIGN Population-based registry linkage study. METHODS Adult cases from the San Francisco AIDS registry (1990-2000) were matched with the California Cancer Registry (1985-2002) to ascertain AR-PCNSL data. Survival time was assessed through 31 December 2007. Risk factors and temporal trends for death were measured using two-sided Kaplan-Meier and Cox analyses. RESULTS Two hundred and seven AR-PCNSL patients were identified: 68% were white, 20% Hispanic, 10% African-American, and 2% Asian. Nineteen percent of patients had central nervous system (CNS) opportunistic infections diagnosed prior to AR-PCNSL. Fifty-seven percent of patients received radiation and/or chemotherapy and 12% used HAART prior to or within 30 days of AR-PCNSL diagnosis. One hundred and ninety-nine patients died (34 deaths/100 person-years). In adjusted analysis, prior CNS opportunistic infection diagnosis increased risk of death (hazard ratio 1.9, P = 0.0006) whereas radiation and/or chemotherapy decreased risk (hazard ratio 0.6, P < 0.0001). AR-PCNSL diagnosis 1999-2002 had a lower mortality risk (hazard ratio = 0.4, P = 0.02) compared to 1990-1995. African-Americans had an increased risk of death compared to whites or Asians (hazard ratio = 2.0, P = 0.007). CONCLUSION OS among AR-PCNSL patients improved over time but remains poor, especially among African-Americans. Prospective evaluation of curative therapy in AR-PCNSL is urgently needed. Accurate diagnosis of CNS mass lesions in patients with AIDS is required and for those with AR-PCNSL, antiretroviral therapy with concomitant AR-PCNSL therapy, and antimicrobial supportive care may improve OS.

Abstract
Treatment of Epstein-Barr virus (EBV)-related lymphomas with lytic-inducing agents is an attractive targeted approach for eliminating virus-infected tumor cells. Zidovudine (AZT) is an excellent substrate for EBV-thymidine kinase: it can induce EBV lytic gene expression and apoptosis in primary EBV+ lymphoma cell lines. We hypothesized that the combination of AZT with lytic-inducing chemotherapy agents would be effective in treating EBV+ lymphomas. We report a retrospective analysis of 19 patients with aggressive EBV+ non-Hodgkin lymphoma, including nine cases of acquired immune deficiency syndrome-associated primary central nervous system lymphoma (AIDS-PCNSL) treated with AZT-based chemotherapy. Our results demonstrate that high-dose AZT-methotrexate is efficacious in treating highly aggressive systemic EBV+ lymphomas in the upfront setting. In primary EBV+ lymphoma cell lines, the combination of AZT with hydroxyurea resulted in synergistic EBV lytic induction and cell death. Further, AZT-hydroxyurea treatment resulted in dramatic responses in patients with AIDS-PCNSL. The combination of AZT with chemotherapy, especially lytic-inducing agents, should be explored further in clinical trials for the treatment of EBV-related lymphomas.

Abstract
Central nervous system (CNS) lymphoma can present a diagnostic challenge. Currently, there is no consensus regarding what presurgical evaluation is warranted or how to proceed when lesions are not surgically accessible. We conducted a review of the literature on CNS lymphoma diagnosis (1966 to October 2011) to determine whether a common diagnostic algorithm can be generated. We extracted data regarding the usefulness of brain and body imaging, serum and cerebrospinal fluid (CSF) studies, ophthalmologic examination, and tissue biopsy in the diagnosis of CNS lymphoma. Contrast enhancement on imaging is highly sensitive at the time of diagnosis: 98.9% in immunocompetent lymphoma and 96.1% in human immunodeficiency virus-related CNS lymphoma. The sensitivity of CSF cytology is low (2%-32%) but increases when combined with flow cytometry. Cerebrospinal fluid lactate dehydrogenase isozyme 5, β2-microglobulin, and immunoglobulin heavy chain rearrangement studies have improved sensitivity over CSF cytology (58%-85%) but have only moderate specificity (85%). New techniques of proteomics and microRNA analysis have more than 95% specificity in the diagnosis of CNS lymphoma. Positive CSF cytology, vitreous biopsy, or brain/leptomeningeal biopsy remain the current standard for diagnosis. A combined stepwise systematic approach outlined here may facilitate an expeditious, comprehensive presurgical evaluation for cases of suspected CNS lymphoma.

Abstract
PURPOSE Combined immunomodulatory and antiviral treatment was administered to three patients with newly diagnosed HIV-associated primary central nervous system lymphoma (PCNSL) in an attempt to improve outcomes. PATIENTS AND METHODS Three patients from our institution who were recently diagnosed with HIV-associated PCNSL received intravenous azidothymidine (AZT) 1.6 gr. bid for two weeks, followed by oral AZT 250mg bid from day 15. In addition, complementary highly active antiretroviral therapy (HAART) with a second nucleoside reverse transcriptase inhibitor (NRTI) plus one protease inhibitor (PI) and interleukin 2 (IL-2) subcutaneously 2 million units twice daily (bid) plus foscarnet 90mg/kg bid were administered on days 1-14. One patient received anti-Epstein-Barr virus (EBV)-maintenance therapy with ganciclovir, followed by cidofovir. RESULTS All patients experienced progressive disease while on induction therapy, and switched early to whole-brain radiation therapy (WBRT) as second line-treatment. No grade 3 or 4 toxicities were observed. Two patients died on days 50 and 166 respectively due to progressive disease. The third patient with histo?logically proven lymphoproliferation and only suspected PCNSL remained alive at 53 months. He was on HAART and remained clinically and neurologically stable. CONCLUSION Although IL-2, HAART, high-dose AZT and foscarnet are used for other HIV-related conditions, they did not demonstrate benefit in lymphoma remission for 2 HIV- associated PCNSL patients. The third patient went into delayed remission after additional radiotherapy and was in good clinical and neurological health status over 53 months after diagnosis.

Abstract
Despite HAART, patients infected with HIV develop NHL at a significantly higher level than the noninfected population. The primary difference between lymphoma in non-HIV-infected individuals and those with ARL is that ARL is consistently high-grade and metastatic. The emergence of ARL is associated with the presence of macrophage viral reservoirs, similar to what has been observed for HAD. HIV-infected macrophages, as seen by histology and HIV p24 staining, are present in approximately half of ARLs. Macrophage reservoirs recruit additional immune cells, including monocytes/macrophages, through the release of chemoattractants. Additionally, TAM are known to promote tumor progression for most cancer types, including lymphomas. This review will highlight and discuss the role of macrophage viral reservoirs in the development and progression of ARLs and hopefully, shed light on this new and interesting field.

Abstract
PURPOSE To report the clinical experience with external beam radiotherapy (RT) for AIDS-related lymphoma (ARL) with or without the involvement of the central nervous system (CNS) in HIV-infected patients. PATIENTS AND METHODS Clinical outcome of 24 HIV-seropositive patients with ARL treated with RT from 1995 to 2004 was reviewed, testing factors associated with outcome. RESULTS After 1 and 5 years, the overall survival was 65% and 35%, respectively. The mean RT dose was 31 Gy after normalization to fractions of daily 2 Gy (range, 7.8-47.2 Gy). Radiotherapy dose was associated with survival in univariate (P = .04) and multivariate analysis (P = .01). Other factors in univariate analysis associated with outcome were viral load (VL), highly active antiretroviral therapy (HAART), ARL stage, and CNS involvement. Patients with CNS involvement achieved complete response in 46% and improved clinical performance was seen in 73%. CONCLUSIONS After chemotherapy, RT in combination with HAART is highly active, and RT should be encouraged especially after suboptimal responses to induction treatment.

Abstract
Implementation of highly active antiretroviral therapy (HAART) has changed the epidemiology, clinical outcome and therapeutic approach of HIV-associated malignancies. Whereas Kaposi sarcoma and primary CNS non-Hodgkin lymphoma have decreased dramatically, systemic non-Hodgkin lymphoma incidence seems unchanged, perhaps increasing as with other tumor incidence. Owing to HAART-induced immune function preservation, response rates to chemotherapy and survival times in patients with HIV-associated malignancies have neared those observed in their HIV-negative counterparts. Hence, intensive regimens have been more and more extensively used with promising results. This may also apply to other therapeutic options, such as biotherapy, and procedures, such as stem cell rescue following high-dose chemotherapy or heterologous stem cell transplant, which have so far been precluded to HIV-infected subjects as a matter of fact. A trend toward a full assimilation of HIV-infected people with cancer and the general population with the same pathology is ongoing.

Abstract
A 40-year-old male presented to medical attention with Pneumocystis jiroveci pneumonia and HIV infection. His CD4+ count was 18 cells per microliter and his HIV viral load (VL) was more than 400,000 copies milliliter. After 3 weeks of antibiotic therapy, he continued to have global cognitive deficits. A brain imaging study showed a right temporal mass, which on biopsy proved to be primary central nervous system lymphoma (PCNSL). He began highly active antiretroviral therapy (HAART) but declined palliative whole-brain radiotherapy (WBRT). Four months later, his CD4+ count had improved to 153 cells per microliter and his HIV VL was less than 75 copies per milliliter. At 36 months follow-up, he remained in complete remission (CR). Through a literature review, we identified 4 additional PCNSL patients who achieved prolonged remission after the initiation of HAART. One patient required WBRT and ventriculo-peritoneal shunting for signs and symptoms of obstructive hydrocephalus. The other 3 patients presented with stable neurologic findings and were treated with HAART alone. The median initial CD4+ count for these patients was 50 cells per microliter (range, 2 to 220 cells per microliter). All 5 remained in CR with a median follow-up of 23.5 (range, 13 to 36) months. For patients who present with PCNSL as their initial AIDS-defining event, stable neurologic findings, and effective HAART options, initial treatment with HAART alone may be possible, reserving WBRT and corticosteroids for those who show signs of impending neurologic demise. Chemotherapy and other novel approaches could also be considered for selected patients with lesser degrees of immune suppression and high baseline functional status.

Abstract
OBJECTIVE This study investigates the changing indications, results, and practice patterns of brain biopsy in patients with acquired immunodeficiency syndrome (AIDS) as treatment evolved with the development of highly active antiretroviral therapy (HAART). METHODS We collected data on 246 patients with AIDS who were undergoing brain biopsy of intracranial lesions. Patients were managed in accordance with a uniform protocol. Patients were divided into two groups of those biopsied in the era before (1992-1996) or after (1997-2001) the use of HAART. RESULTS The introduction of HAART led to a steep decrease in the number of biopsies performed annually. The protocol functioned well. Diagnoses were obtained for 92.3% of patients. Lymphoma was the most frequent diagnosis (52.9% of patients), followed by progressive multifocal leukoencephalopathy (18.9% of patients) and toxoplasmosis (8.1% of patients). No patient who underwent lesion biopsy for reasons of negative toxoplasmosis titers or atypical radiology evaluation was diagnosed with toxoplasmosis. Nineteen patients who experienced failed toxoplasmosis treatment were diagnosed with toxoplasmosis. Toxoplasmosis titers had a high specificity and a negative predictive value. Patients with progressive multifocal leukoencephalopathy or nondiagnostic biopsies were more likely to have solitary lesions. The average Karnofsky performance score at the time of biopsy was 72.4, which is still within the range of independent functioning. Significant intracerebral hemorrhages were only observed in patients with lymphoma who also had low platelet counts. CONCLUSION Although the number of patients with AIDS who require brain biopsy has decreased, the procedure still has merits. The paradigm we developed was useful for selecting patients for early biopsy. Patients with AIDS who also have intracerebral lesions should have toxoplasmosis titers performed, and those whose titers are negative for toxoplasmosis should undergo early brain biopsy.

Abstract
Among individuals with HIV-infection, coinfection with oncogenic viruses including EBV, HHV-8, and HPV cause significant cancer-related morbidity and mortality. It is clear that these viruses interact with HIV in unique ways that predispose HIV-infected individuals to malignant diseases. In general, treatment directed specifically against these viruses does not appear to change the natural history of the malignant disease, and once the malignancy develops, if their health permits, HIV-infected patients should be treated using similar treatment protocols to HIV-negative patients. However, for the less frequent HIV-related malignancies, such as PEL, or MCD, optimal treatments are still emerging. For certain AIDS-defining malignancies, it is clear that the widespread access to HAART has significantly decreased the incidence, and improved outcomes. However, for other cancers, such as the HPV-related tumors, the role of HAART is much less clear. Further research into prevention and treatment of these oncogenic virally mediated AIDS-related malignancies is necessary.

Abstract
From a cohort of 9621 human immunodeficiency virus type 1-infected individuals, we identified 61 patients with primary central nervous system lymphoma (PCL) who had a median survival of 1.3 months. We compared clinicopathologic variables of patients who were treated in the pre-highly active antiretroviral therapy (HAART) and HAART eras and investigated whether exposure to antiretroviral agents with differing cerebrospinal fluid penetrations was associated with risk for PCL. All statistical tests were two-sided. Incidence of PCL was lower in the HAART era (1.2 cases per 1000 patient-years, 95% confidence interval [CI] = 0.8 to 1.9) than in the pre-HAART era (three cases per 1000 years, 95% CI = 2.1 to 4.0; P<.001), and overall survival was longer (median survival = 32 days, range = 5-315 days, versus 48 days, range = 15-1136 days; log rank P = .03). In the HAART era, fewer patients had prior acquired immunodeficiency syndrome-defining illnesses than in the pre-HAART era (64% versus 90%; P = .013), and patients were more likely to have the diagnosis of PCL confirmed histologically or by polymerase chain reaction (77% versus 26%; P<.001). Exposure to specific antiretroviral agents was not associated with risk for PCL.

Abstract
This study investigates delay in diagnosing primary central nervous system lymphoma (PCNSL), which has a variable clinical and radiological presentation. Early diagnosis and treatment may improve survival and cause less sequela in PCNSL. Medical records of all new cases of PCNSL morphologically verified while alive or by autopsy in Norway in 1989-1998 were reviewed (n = 74). The time from initial symptom to final morphological diagnosis of PCNSL had a median (mean, range) of 70 (106, 22-330) days in 16 AIDS patients and 75 (157, 8-1285) days in 58 non-AIDS patients. Among non-AIDS patients, the time to diagnosis was longer in patients with no tumour in the first neuroimaging report after initial symptom (p = 0.001). Median (mean, range) time from initial symptom to neuroimaging was 14 (25, 1-60) days in AIDS patients and 21 (88, 1-1095) days in non-AIDS patients. In the non-AIDS group, those presenting with personality change or visual disturbance had more delayed imaging than the others. The time from first neuroimaging examination to final diagnosis in non-AIDS patients had a median (mean, range) of 28 (69, 1-845) days, and was longer when no tumour was indicated in the imaging report (p = 0.005) and if first biopsy did not confirm the diagnosis (p = 0.02). All AIDS patients had their diagnosis of PCNSL first established by autopsy. The time from first neuroimaging to autopsy had a median (mean, range) of 48 (81, 10-270) days. There is a considerable delay in the diagnosis of PCNSL and strategies for earlier diagnosis are thus needed. Physicians should consider early neuroimaging in patients with personality changes or visual disturbance, early renewed imaging in patients with persistent neurological symptoms but no tumour on initial imaging, and early/repeated biopsy of focal brain lesions in both AIDS patients and non-AIDS patients.

Abstract
Primary central nervous system lymphoma is a stage 1E non-Hodgkin's lymphoma confined to the nervous system. It is seen in immunocompetent and immunodeficient populations, the latter group associated with the Epstein-Barr virus. Primary central nervous system lymphoma can affect the brain, leptomeninges, spinal cord or eyes. The institution of high-dose methotrexate-based regimens and whole-brain radiation therapy has significantly increased survival, but neurotoxicity is high in patients over 60 years of age. Despite these advances, 50% of patients initially treated will relapse. Recent investigations include the use of rituximab (immunotherapy) and stem-cell transplantation, as well as regimens without whole-brain radiation therapy in the elderly. The optimal treatment regimen is yet to been determined.

Abstract
Before the introduction of highly active antiretroviral therapy (HAART), human immunodeficiency virus (HIV)-related primary central nervous system lymphoma (PCNSL) represented one of the most prevalent causes of focal brain lesions in HIV-infected people. The prognosis of PCNSL was very poor, with median survival time not exceeding 2 months. Brain biopsy was the method of choice for the definitive diagnosis, but it was and remains an invasive procedure with morbidity and mortality as well as considerable costs in terms of patients' management and quality of life. The strict association between AIDS-PCNSL and Epstein-Barr virus led to the suggestion that EBV DNA in cerebrospinal spinal fluid (CSF) might serve as a diagnostic marker, reducing the time required for diagnosis and allowing a minimally invasive approach. The clinical usefulness of this methodology has been largely demonstrated through clinical practice. After the introduction of HAART in clinical practice, a survival benefit has been observed for most persons with acquired immunodeficiency syndrome (AIDS)-associated opportunistic infections and cancers. In particular, for patients with non-Hodgkin lymphoma, a higher likelihood of response to chemotherapy as well as a longer survival has been found as a consequence of the use of combined antiretroviral therapy. Although larger studies did not show significant changes in survival of HIV-infected patients with PCNSL in the era of HAART, small case series and anecdotal reports showed the benefit of HAART in the treatment of PCNSL. Nevertheless, these patients' survival still remains very poor and it could be hypothesized that, other than specific cancer prognostic determinants and severe immunodeficiency, viral pathogenesis as well as EBV-specific immunologic dysfunction may be responsible.

Abstract
Primary central nervous system lymphoma (PCNSL) can develop in the setting of profound immunosuppression, including late-stage infection with HIV. The management of such patients has yet to be defined optimally and differs substantially from that of immunocompetent patients who have PCNSL. The clinical features, diagnosis, and management of AIDS-related PCNSL are reviewed. The authors focus on commonly encountered diagnostic and therapeutic dilemmas and explore some promises and pitfalls of Epstein-Barr virus-directed therapies.

Abstract
We retrospectively analyzed 32 cases of primary central nervous system lymphoma (PCNSL). Five cases were diagnosed in the period 1987-1994, for 27 cases in the period 1995-2002. There were 17 men and 15 women whose median age was 69 years. Three patients were immunodeficient. The commonest symptoms were focal deficit (16 patients) and cognitive/behaviour disturbances (14 patients). Radiologically, a total of 47 contrast-enhancing lesions were observed in 32 patients; 18 patients had deep-seated lesions. All but two patients underwent histological diagnosis following craniotomy (11 patients) and/or stereotaxic biopsy (22 patients); diagnosis was obtained on CSF cytology in one patient with a third ventricle tumour. In the last patient, the diagnosis was based on the finding of marked tumour shrinkage under corticotherapy, despite two negative histological examinations. Treatment included surgical resection (10 patients), chemotherapy (25 patients) and/or radiotherapy (12 patients). According to the therapeutic recommendations of the GELA (Groupe d'Etude des Lymphomes de l'Adulte), 19 patients received at least two courses of high-dose methotrexate; intrathecal chemotherapy was used in 20 patients with methotrexate and/or cytosine arabinoside. Radiation therapy consisted of whole brain irradiation followed by a boost on tumour site. Nine patients received a combined treatment of chemotherapy and radiotherapy. Twelve patients showed rapid progression to death. At the time of last contact, 28/32 patients (88%) had died, all from PCNSL disease or from complications due to its treatment. The median survival time was 13.9 months. We conclude that PCNSL is an increasingly frequent tumour. The diagnosis is obtained by stereotactic biopsy in the majority of cases. The prognosis appears dismal despite an intensive multidisciplinary therapeutic approach.

Abstract
As we enter the third decade of the AIDS epidemic, it is apparent that a large number of cancers are more common in people with the human immunodeficiency virus type 1 (HIV). Non-Hodgkin's lymphoma (NHL) remains the second most common tumour in such patients. At the onset of the epidemic, dose-intense combination regimens were used but these were quickly abandoned in favour of dose-modified strategies because of difficulties in tolerating aggressive chemotherapy in the presence of underlying immunosuppression. With the improvements in supportive care including more effective anti-retroviral therapies, colony-stimulating factors and prophylaxis against opportunistic infections, we are returning to the traditional chemotherapeutic approaches similar to those utilised in the non-HIV infected individual including infusional regimens. In this review, we discuss the evidence for choosing particular therapies in patients with AIDS-related NHL.

Abstract
BACKGROUND The current study evaluated factors influencing survival in patients diagnosed with human immunodeficiency virus (HIV)-related primary central nervous system lymphoma (PCNSL), with a focus on the effects of therapeutic radiotherapy (RT) and highly active antiretroviral therapy (HAART). METHODS A retrospective chart review of patients with a diagnosis of HIV-related PCNSL at one of five university hospitals between 1987 and 1998 was performed. Clinical details including antiretroviral agent use, brain imaging scan results, RT use, and survival outcomes were recorded. RESULTS One hundred eleven patients with HIV-related PCNSL were identified. The annual incidence decreased significantly between 1992 and 1995 and between 1996 and 1998 (P = 0.04). The median survival period was 50 days (mean, 109 days; range, 4-991 days), with improved survival for patients diagnosed after 1993. Patients treated with two or more antiretroviral agents had improved survival (P = 0.01), as did patients who received RT (P < 0.0001). For patients who received RT, completion of the prescribed course and treatment to > or = 30 Gray (Gy) independently predicted a more favorable outcome. RT used in conjunction with antiretroviral therapy involving two or more agents had an additive positive effect on survival. For patients who did not receive RT, poor performance status and encephalopathy predicted a shorter survival duration. CONCLUSIONS The results of the current study suggest that HAART and treatment with RT to > or = 30 Gy improve survival for patients with HIV-related PCNSL. This combination of therapies may provide a standard of care as the basis for further trials of chemotherapy, novel adjunctive treatment, and quality of life assessment.

Abstract
OBJECTIVE To determine the effects of highly active antiretroviral therapy (HAART) on survival in AIDS-related primary central nervous system lymphoma (PCNSL). METHODS Survival in consecutive patients with PCNSL at a large county teaching hospital from 1995 to 2001 were analyzed by the log rank test and Cox proportional hazards ratios (HR) were calculated for factors potentially affecting survival. RESULTS During the study period, 25 patients were diagnosed with PCNSL: 19 definite and 6 probable. At diagnosis, median CD4 cell count was 12 x 10(6) cells/l (range 1-151) and median HIV viral load was 5.3 log(10) copies/ml (range 3.9-5.9). Sixteen patients died (median survival 87 days; range, 0 to > 2112). Longer survival was noted for patients who received HAART after diagnosis [HR for death, 0.06; 95% confidence interval (CI), 0.01-0.48]. Six of seven HAART-treated patients were alive versus 0/18 untreated patients at a median follow-up time of 667 days (P = 0.0007 by log rank test). A survival benefit was seen for patients who had >/= 0.5 log(10) copies/ml decrease in HIV viral load after diagnosis (n = 6; HR, 0.07; 95% CI, 0.01-0.55) and for patients with a significant CD4 cell rebound (increase >/= 50 x 106 cells/l) in response to HAART (n = 6): all survived versus 0/19 survived (P = 0.0003). Cranial radiation therapy (n = 13) prolonged survival (HR, 0.20; 95% CI, 0.07-0.58). Median survival was only 29 days for 11 patients who received neither radiation nor HAART. CONCLUSIONS Receipt of HAART after diagnosis is associated with a significantly longer survival in patients with AIDS-related CNS lymphoma.

Abstract
The treatment of HIV-related lymphomas is evolving in the era of HAART. Standard-dose chemotherapy and dose-intensive therapies appear to be feasible. Whether outcomes are improved with combination chemotherapy and HAART remains unclear. Efforts aimed at developing pathogenic-based therapies will continue as the mechanisms of HIV lymphomagenesis are elucidated.

Abstract
Primary nervous system lymphoma (PNSL) is a rare type of non-Hodgkin's lymphoma confined to the nervous system. Although significant progress has been made in the treatment of PNSL over the past decade, patients with this disease are rarely cured. Until recently, whole brain radiation therapy has been the standard treatment for PNSL. However, whole brain radiation therapy is associated with a high relapse rate and late neurotoxicity after chemotherapy, especially in patients older than 60 years of age. Methotrexate-based chemotherapy has become the standard approach to treat patients with newly diagnosed PNSL. Ongoing research efforts are focused on identifying chemotherapeutic agents with good antilymphoma activity that penetrate the blood-brain barrier. The roles of intrathecal chemotherapy and blood-brain barrier disruption are not fully defined. Given the rarity of this tumor, patients with PNSL should be referred to tertiary cancer centers where ongoing clinical trials are underway to identify the optimal treatment of PNSL.
