Abstract
PURPOSE Systemic chemotherapy is the treatment of choice for AIDS-related advanced Kaposi sarcoma. One principal schedule combines adriamycin (doxorubicin), bleomycin, and vincristine (ABV). We analysed the plasma concentrations of low-dose doxorubicin (Dx) and its metabolites doxorubicinol, 7-deoxydoxorubicinone, doxorubicinone, doxorubicinolone, and 7-deoxydoxorubicinolone in AIDS-patients to define patient-group and dose-specific pharmacokinetic parameters. MATERIALS AND METHODS A previously described high-performance liquid chromatographic (HPLC) method and a population approach with non-linear mixed effects modelling (NONMEM) were used for analysis and subsequent modelling of the time-concentration data of low-dose Dx and metabolites in seven patients with AIDS-related advanced Kaposi sarcoma. Patients received Dx 20 mg m(-2), bleomycin 15 U m(-2) and vincristine 2 mg as a 30-min intravenous infusion each. Blood samples were collected up to 72 h after the start of Dx treatment. WinNonlin software version 4.1 was used for non-compartmental analysis and NONMEM software version V for compartmental analysis. Covariate analysis was performed for various clinical and laboratory parameters. RESULTS Non-compartmental analysis yielded an area under the plasma concentration-time curve (AUC) for Dx of 566 mug h L(-1), a maximum plasma concentration (c(max)) of 599 mug L(-1) and an elimination half-life (t(1/2)) of 30.8 h. Compartmental analysis resulted in a two-compartment model with first-order elimination, which best fitted the concentration-time data. Model estimate for Dx clearance was 61.8 L h(-1), for intercompartmental clearance (Q) 112 L h(-1), for the volume of the central compartment (V(1)) 23.3 L, and for the volume of the peripheral compartment (V(2)) 1,130 L. Metabolite data could adequately be estimated by NONMEM using single-compartment models. Graphical plots of residuals versus time for all metabolites yielded no evidence of non-linear pharmacokinetic behaviour. Laboratory parameters of liver and renal function were all in the normal range and their inclusion in the pharmacokinetic model did not improve data fit. A final jack-knife analysis was performed. CONCLUSIONS Concentration-time data for low-dose Dx and metabolites in the ABV-regimen are best described by a two-compartment model with first-order elimination. The results confirm that the aglycones doxorubicinone, 7-deoxydoxorubicinone, and doxorubicinolone can be reliably detected in the studied patient group and implemented into a common metabolic model. Model estimates suggest that pharmacokinetic parameters are similar for low-dose Dx and higher-dosed Dx. As the role of the aglycones is still poorly understood, despite their potential clinical relevance, their analysis should be implemented in future pharmacokinetic and pharmacodynamic studies of Dx.

Abstract
Alternative targets of attack of the human immunodeficiency virus (HIV) are necessary in light of infection persistence due to onset of resistance after conventional reverse transcriptase and protease inhibitor therapy. We have recently shown that the cancer chemotherapeutic agent bleomycin (BLM) dose-dependently inhibits HIV-1 replication. The mechanism of this viral inhibition in vitro was investigated. Cell-free wild-type virions were affected directly by BLM in the presence of H2O2, as shown by a 38% decrease of viral infectivity. Viral inhibition by BLM did not proceed via NF-kappaB inhibition. The viral R/U5 DNA product was reduced by 70% without any effect on reverse transcriptase activity. In both a cell-free system as well as two-cell systems the antiviral dependence of BLM on iron and oxidant species was demonstrated. Bleomycin seems to inhibit HIV-1 replication through the same properties that make it a suitable anti-cancer agent. The results presented in this study describe a novel mechanism of HIV-1 inhibition with potential application in viral infections. The anti-HIV effects of BLM in patients receiving this drug in combination with HAART should be carefully monitored in order to evaluate the clinical significance of the findings described in this study.

Abstract
BACKGROUND Patients with acquired immunodeficiency syndrome (AIDS)-associated lymphoma/leukemia have a poor prognosis and are frequently treated with low-intensity therapy. The authors investigated the feasibility and efficacy of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD), a dose-intensive chemotherapy regimen, in patients with AIDS-associated Burkitt lymphoma/leukemia, as well as the possible impact of highly active antiretroviral therapy (HAART) in these patients. METHODS Thirteen patients with AIDS-associated Burkitt lymphoma (six patients) or leukemia (acute lymphoblastic leukemia; seven patients) were treated with hyper-CVAD alternating with high-dose methotrexate and ara-C for a total of eight cycles. Nine patients received HAART from the start of induction chemotherapy (seven patients) or later in the course of chemotherapy (two patients). The median patient age was 43 years (range, 32-55). Nine patients were diagnosed with human immunodeficiency virus (HIV) infection at the time of diagnosis of Burkitt lymphoma/leukemia; the other 4 patients had been diagnosed with HIV infection for a median of 37 months (range, 18-137) prior to the diagnosis of Burkitt lymphoma/leukemia. The median absolute CD4 count from the 9 patients with evaluable counts was 77 cells/microL (range, 9-544); only one patient had a count > 200/microL. RESULTS Twelve patients (92%) achieved a complete remission (CR) and one achieved a partial response (PR). Eight patients continued in CR after a median of 31 months (range, 7-45) at the time of writing. Five patients were alive and in CR over two years later. The median survival was 12 months, with 48% of patients alive after 2 years. Six of seven patients who received HAART from the start of chemotherapy were alive and in CR after a median of 29 months (range, 7-45). The four patients who did not receive HAART died. The regimen was universally myelosuppressive, but the toxicity profiles, recoveries from myelosuppression, and incidences of infectious complications were similar to that of non-HIV patients with Burkitt lymphoma/leukemia treated with the same regimen. CONCLUSIONS Hyper-CVAD is an effective regimen for patients with AIDS-associated Burkitt lymphoma/leukemia, with acceptable toxicity. The combination of hyper-CVAD and HAART is associated with long-term survival in patients with the two diseases, which, until recently, were both considered invariably fatal and almost futile to treat medically.

Abstract
P-glycoprotein is a product of the multidrug resistance (MDR-1) gene. In non-Hodgkin's lymphoma, less than 20% of untreated de novo lymphomas express MDR-1 compared with approximately 50% after failure of chemotherapy. We wished to study the expression of MDR-1 in AIDS-related non-Hodgkin's lymphoma (AIDS-NHL). Tissue biopsies from 50 patients with newly diagnosed AIDS-NHL were studied by immunohistochemical analysis using C494, a monoclonal antibody specific for the MDR-1 isoform of P-gp. MDR-1 expression was correlated with patient demographics, lymphoma characteristics, response to chemotherapy, and survival. Forty-six males and four females with a median age of 38 years (range 26-63) were studied. A prior AIDS-defining opportunistic infection was reported in 35 patients (70%). The median CD4+ lymphocyte count was 69/mm(3) (range 0-920). Thirty-two patients (63%) had received prior anti-HIV therapy, including a protease inhibitor in five (10%). Pathologic types consisted of diffuse large cell in 13 (26%), immunoblastic in 13 (26%), small non-cleaved in 22 (44%), and high grade not otherwise specified in two (4%). The majority of patients (76%) had stage III/IV disease. Pre-treatment lymphoma tissues from 33 patients (66%) stained positively for MDR-1. MDR-1 positive patients had a significantly lower complete remission rate compared to MDR-1 negative patients (33 versus 65%, P=0.042). Duration of complete response was significantly longer in MDR-1 negative patients compared with MDR-1 positive patients (not reached versus 9.9 months, P=0.003). Strategies to overcome MDR-1 expression may be important for initial treatment in patients with AIDS-NHL.

Abstract
The incidence of non-Hodgkin's lymphoma in individuals infected with HIV is approximately 60- to 100-fold increased over the general population. The majority of patients with AIDS-related lymphoma (ARL) present with stage III-IV disease and with B-symptoms. They often have multiple extranodal localisations, with a high incidence of central nervous system involvement. Histologically, most tumours are either diffuse large cell lymphomas or Burkitt lymphomas. Several factors, such as disrupted immune surveillance, Epstein-Barr virus infection, chronic antigenic stimulation, cytokine dysregulation and the acquisition of genetic lesions, are thought to contribute to the pathogenesis. Patients with ARL have a poor prognosis: overall survival ranges from 1.5 to 18 months. The most important adverse prognostic factors are poor performance status, a low CD4+ cell count and a history of opportunistic infections. Results of treatment with polychemotherapy compare unfavourably to results in patients without HIV infection. Since the advent of highly active antiretroviral therapy (HAART), there appears to be a decrease in the incidence of ARL. In addition, the use of HAART in combination with chemotherapy and the use of new treatment modalities may improve the outcome of this disease.

Abstract
It has been suggested that the combination of cancer chemotherapy with antiviral therapy is helpful for the containment of lymphomas in HIV-infected patients. Since we have recently shown that the nucleic acid binding chemotherapeutic agent bleomycin in itself has antiviral properties, we looked to see if there was any possible synergy with current anti-HIV agents. Combinations of zidovudine, indinavir or ritonavir with bleomycin, synergistically inhibited HIV-1(AT) replication in stimulated peripheral blood lymphocytes (combination index at 50% virus inhibition was 0.427, 0.604 and 0.535, respectively) and this synergism was not accompanied by any synergistic effects on cytotoxicity. We conclude from these data that further studies to investigate the clinical efficacy of combinations of antiviral and cancer chemotherapeutic agents are warranted in relation to viral load improvement.

Abstract
Bone marrow involvement is reported in approximately 25% of patients with newly diagnosed acquired immunodeficiency syndrome-related lymphoma (ARL). Studied were 291 patients with ARL, diagnosed and treated at one medical center between 1984 and 1998. Clinical, immunologic, and pathologic characteristics of patients with bone marrow involvement were compared with those of patients without marrow involvement. Bone marrow involvement was present in 55 patients (19%). Small noncleaved lymphoma was diagnosed in 38% of the entire group and was the most common pathologic subtype in patients with bone marrow involvement (55% versus 34%; P =.008). Analysis of complete blood counts revealed a median hemoglobin level of 10.6 g/dL in both marrow-positive and marrow-negative groups. In contrast, a platelet count lower than 100 000/microL was more common in patients with bone marrow involvement (27% versus 11%; P =.02). Patients with marrow involvement were more likely to have leptomeningeal (cerebrospinal fluid [CSF]) lymphoma than patients whose marrows were uninvolved (24% versus 7%; P <.001) and were also more likely to have high lactate dehydrogenase (LDH) (P =.002), bone involvement (P <.001), and/or systemic B symptoms including fever, night sweats, and/or weight loss (P =.05). Median survival did not differ between marrow-positive and marrow-negative groups. On multivariate analysis, factors associated with decreased survival of marrow-positive patients included greater than 50% involvement (P =.002), systemic B symptoms (P =.008), and high-grade histologic type (P =.035). Marrow involvement in ARL correlates with small noncleaved pathology, thrombocytopenia lower than 100 000 mm(3), high LDH, and lymphomatous involvement of the CSF. Survival is statistically shorter in patients with greater than 50% marrow involvement, high-grade pathology, and/or systemic B symptoms.

Abstract
The incidence of non-Hodgkin's lymphoma (NHL) is increased by approximately 100-fold in patients with advanced HIV infection. Clinical presentations may include systemic lymphoma, primary central nervous system (CNS) lymphoma, and primary effusion lymphoma. Systemic lymphoma is the most common presentation, is almost always of intermediate or high-grade histology and B-cell phenotype, and usually involves extranodal sites. The disease is potentially curable with combination chemotherapy used for immunocompetent patients with lymphoma, although cure is achieved in only approximately 10-35% of patients. Primary CNS lymphoma may be difficult to distinguish from cerebral infection. The prognosis is very poor, although approximately 10% of patients selected for therapy may survive beyond 1 year with brain irradiation. Attention to infection prophylaxis and antiretroviral therapy is important. Evidence suggests that highly active antiretroviral therapy (HAART) has resulted in a decreased incidence of lymphoma, and that patients with systemic lymphoma treated in the post-HAART era have a better prognosis.

Abstract
Over time, the epidemiologic and demographic characteristics of AIDS have changed in the United States, while the use of highly active antiretroviral therapy has changed the natural history of the disease. The goal of the study was to ascertain any changes in the epidemiologic, immunologic, pathologic, or clinical characteristics of AIDS-related lymphoma (ARL) over the course of the AIDS epidemic. Records of 369 patients with ARL diagnosed or treated at a single institution from 1982 through 1998 were reviewed. Single institutional data were compared to population-based data from the County of Los Angeles. Significant changes in the demographic profile of patients with newly diagnosed ARL have occurred, with the later time intervals associated with a higher prevalence in women (P = .25), in Latino/Hispanic individuals (P < .0001), and in those who acquired human immunodeficiency virus (HIV) heterosexually (P = .01). These changes were similar in both countywide, population-based analyses and in those from the single institution. The median CD4+ lymphocyte count at lymphoma diagnosis has decreased significantly over the years, from 177/dL in the earliest time period (1982-1986), to 53/dL in the last time period from 1995 to 1998 (P = .0006). The pathologic spectrum of disease has also changed, with a decrease in the prevalence of small noncleaved lymphoma (P = .0005) and an increase in diffuse large cell lymphoma (P < .0001). Despite changes in the use of antiretroviral or chemotherapy regimens, the median survival has not significantly changed.

Abstract
PURPOSE To outline the incidence, presenting features, treatment response, and outcome of human immunodeficiency virus (HIV)-associated malignancies in infancy and childhood, together with the estimated risk of HIV-associated cancer in children born to mothers infected with HIV. PATIENTS AND METHODS The Italian Register for HIV Infection in Children collected data by specific registration and follow-up forms. By March 1999, 5,060 children were recruited, including 4,889 with perinatal exposure to HIV-1. Overall, 1,331 infected children were enrolled onto the Register and classified according to current Centers for Disease Control criteria; of them, 1,163 were vertically infected (24% of those with perinatal exposure). Of these 1,163, 569 (49%) were considered to have been prospectively followed-up since they had been registered at birth or within the first 3 months of age. RESULTS Of the 1,331 children observed for a median time of 6.5 years, 35 developed 36 malignancies, four of which occurred in patients with blood-borne risk. For the 1,163 vertically infected children, the cumulative number of years of observation was 7,178 child-years and the cumulative incidence of HIV-associated tumors was 4.18 per 1,000 children/yr (95% confidence interval [CI], 2.92 to 5.98). When only the 569 vertically infected children prospectively followed up since birth were considered, the cumulative number of years of observation was 2,803 child-years. In this group, 10 tumors were observed, with a cumulative incidence of HIV-associated tumors of 3.57 per 1,000 children per year (95% CI, 1.92 to 6.63). CONCLUSION The risk of cancer was significantly higher but not restricted to symptomatic and/or immune-compromised children. Cancer-directed treatment should be given promptly to these patients, who have a fair chance to survive their tumor in view of potential highly aggressive antiretroviral therapy-associated improvement in survival and quality of life.

Abstract
To ascertain the results of standard ABVD chemotherapy (doxorubicin, bleomycin, vinblastine, dacarbazine) in HIV-infected patients with newly diagnosed Hodgkin's disease (HD), a nonrandomized, prospective, multiinstitutional clinical trial was conducted by the AIDS Clinical Trials Group (ACTG), in HIV-infected patients with Hodgkin's disease. All patients received the standard ABVD regimen, with granulocyte-colony-stimulating factor (G-CSF). Antiretroviral therapy was not used. Between May, 1992 and August, 1996, 21 patients were added to the study and treated. The median CD4 count was 113 cells/mm3, and 29% had a history of a clinical AIDS-defining condition before diagnosis of HD. Systemic "B" symptoms were present in 90% at diagnosis. Stage IV HD was present in 67%, with bone marrow involvement in 12 (57%). Nodular sclerosis HD was present in 38%, with mixed cellular disease in 31%. Among all patients entered and treated, complete remission (CR) was attained in 9 (43%; 90% confidence interval [CI], 24%-63%), whereas partial response occurred in 4 (19%), leading to an overall objective response rate of 62% (90% CI, 42%-79%). Despite routine use of G-CSF, 10 patients (47.6%) experienced life-threatening neutropenia, with absolute neutrophil counts <500 cells/mm3. In all, nine opportunistic infections occurred in 6 patients (29%) during the study or shortly thereafter. Median survival was 1.5 years. Results of this study suggest that alternative treatment strategies should be explored, including use of chemotherapy together with antiretroviral therapy.

Abstract
AIDS-related non-Hodgkin lymphomas (AIDS-NHL) consistently derive from B-cells and are characterized by extreme clinical aggressiveness. At histological level, AIDS-NHL are classified as AIDS-related Burkitt's lymphoma (AIDS-BL), AIDS-related diffuse large cell lymphoma (AIDS-DLCL) and AIDS-related primary effusion lymphoma (AIDS-PEL). The role of cytokines in the pathogenesis and management of AIDS-NHL has been studied to a certain extent. Production of large quantities of human IL-10 occurs frequently in AIDS-BL and correlates with latent EBV infection of the tumor clone. Lesser amounts of the cytokine are released in EBV negative cases. The pathogenetic role of IL-10 in AIDS-BL is suggested by the observation that IL-10 antisense oligonucleotides inhibit proliferation of the lymphoma. A significant fraction of AIDS-BL cell lines produce TNFbeta. Among AIDS-NHL, the release of TNFbeta appears to be specific for AIDS-BL. The pathogenetic relevance of TNFbeta in lymphomagenesis is suggested by the observation that some BL cell lines use TNFbeta as an autocrine growth factor. Some cases of AIDS-BL, particularly those carrying EBV infection, also secrete IL-6, IL-7 and IL-12. With respect to AIDS-DLCL, many cases express the IL-6R, rendering these cells responsive to the paracrine stimulation by the IL-6 produced by nearby T-cells, macrophages and endothelial cells which are frequently abundant in these tumor samples. The tumor clone itself, however, generally fails to release IL-6. AIDS-PEL is characterized by secretion of large amounts of IL-6 and IL-10. Some PEL cases also release oncostatin M. Apart from human IL-6, PEL also express viral IL-6, which is encoded by the HHV-8 genome. The biological relevance of both IL-6 and IL-10 in PEL proliferation and growth has been recently clarified in vitro and in vivo. Overall, these data suggest that activation of different cytokine loops clusters with different clinico-pathologic categories of AIDS-NHL and may represent the potential target of novel therapeutic strategies.

Abstract
The functional recovery of the immune system in HIV-infected persons receiving HAART and the role of adjuvant immune therapy are still matters of intensive investigation. We analysed the effects of HAART combined with cytokines in 22 naive asymptomatic individuals, randomized to receive HAART (n = 6), HAART plus a low dose (1000 000 U/daily) of rIL-2 (n = 8), and HAART plus rIL-2 after previous administration of granulocyte colony-stimulating factor (n = 8). After 3 months of therapy, increased CD4+ T cell counts and diminished viral loads were observed in all patients, independently of cytokine addition. A decreased expression of CD95 (Apo 1/Fas) was evident in all groups when compared with values before therapy. The percentages of peripheral blood mononuclear cells (PBMC) expressing CD95 after therapy decreased by 15%, 22% and 18% in the three treatment groups, respectively (P < 0.05). Analysis of PBMC subsets demonstrated that CD95 expression was significantly reduced on CD45RA+CD62L+ naive T cells (25.3%, 22.4%, and 18.6%, respectively; P < 0.05) in each group, after therapy. Accordingly, all patients showed a reduced rate of in vitro spontaneous apoptosis (P < 0.05). Another effect induced by HAART was a significant increase in IL-2Ralpha expression on total PBMC (P < 0.05), independently of cytokine addition. Altogether, our results suggest that very low dose administration of rIL-2 (1000 000 U/daily) may be not enough to induce a significant improvement in the immune system as regards HAART alone. The employment of higher doses of recombinant cytokines and/or different administration protocols in clinical trials might however contribute to ameliorate the immune reconstitution in patients undergoing HAART.

Abstract
B cell hyperactivation accompanies HIV infection and is believed to contribute to the increased incidence of B cell lymphoma in persons with AIDS. To examine B cell activation which precedes the development of AIDS-associated lymphoma, we measured levels of two B cell stimulatory molecules, soluble CD23 (sCD23) and interleukin 6 (IL6), in the serum of HIV-infected individuals prior to the diagnosis of lymphoma. Serum sCD23 was elevated in those subjects who developed lymphoma, compared to AIDS, HIV+, and HIV- controls (P = 0.001). Serum IL6 was significantly elevated in subjects who developed Burkitt's/small noncleaved cell lymphoma (BL/SNC, P = 0.01), but not in those subjects who developed large cell, immunoblastic, or central nervous system lymphomas, compared to CD4-matched AIDS controls who did not have lymphoma. These results suggest that lymphomagenesis of the BL/SNC subtype of AIDS lymphoma reflects B cell hyperactivation of a different nature from that which precedes other subtypes of AIDS-associated B cell lymphoma.

Abstract
The incidence of intermediate and high grade B-cell non-Hodgkin's lymphomas in HIV-infected individuals is approximately 60 times greater than in the general population. These AIDS-related lymphomas (AIDS-NHL) are a late manifestation of HIV infection and may increase in frequency as patients live longer with highly active antiretroviral therapy and effective prophylaxis of opportunistic infections. AIDS-NHL have unique clinical and pathological features that are different from non-Hodgkin's lymphomas in the general population. Histologically AIDS-NHL are either high (2/3) or intermediate (1/3) grade lymphomas. Clinically AIDS-NHL have a preponderance for extranodal involvement with central nervous system being the most common site for this. In addition to the clinical and pathological features of AIDS-NHL, a current knowledge of their pathogenesis and treatment options are presented in this review.

Abstract
The appearance in 1981 of a usually rare malignancy, Kaposi's sarcoma, in homosexual men [1] was one of the first harbingers of an epidemic caused by a retrovirus, human immunodeficiency virus (HIV), which causes the acquired immunodeficiency syndrome (AIDS). Lymphoid and other malignancies were also increased, most strikingly non-Hodgkin's lymphoma and primary central nervous system (CNS) lymphoma. Advances in molecular biology, immunology, virology, and anti-viral therapy have combined to create unique research opportunities. One developing theme is the role of viral co-infection and malignancy. Human herpes virus 8 (HHV8), Epstein-Barr virus (EBV) and papilloma virus each may have a causal role in the development of HIV-associated malignancy. New antiretroviral therapies are able to substantially reverse or delay the profound immunosuppression of HIV infection. The changes in the epidemiology of malignancies, and understanding the mechanism of action of these new therapeutics provide research opportunities to understand the pathogenesis of these malignancies. The opportunities to discover the consequences of T-cell based immunodeficiency and the interactions with specific viral pathogens will likely lead to progress in HIV treatment and new strategies for other malignancies.

Abstract
Advances in antiretroviral therapy have resulted in significant improvement in virological markers and clinical end points. However, studies have demonstrated that HIV can be recovered from patients in whom HIV RNA has been undetectable for prolonged periods of time, suggesting that the elimination half-life of latently infected cells may be longer than previously speculated. When used in the appropriate setting, cytoreductive agents may help expedite the elimination of the long-lived viral reservoir, and result in shorter administration of antiviral agents. In this article we discuss the potential use of cytoreductive agents as adjunctive therapy to antiretrovirals. In addition, we review those agents most likely to impact the viral reservoir and describe ongoing clinical trials designed to define the effect of cytoreductive therapy on those reservoirs. If a positive effect is demonstrated, these agents could ultimately be a powerful addition to the potent drugs currently being used to block HIV replication.

Abstract
In the US over one million persons are currently infected with the HIV, over half a million have had AIDS, and over 300,000 have died from AIDS. Worldwide, it is estimated that more than 17 million people are currently infected with HIV, and over 1,200,000 cases of AIDS have been reported to the World Health Organization. By some estimates, up to 40% of patients with AIDS will ultimately develop some form of cancer. Non-Hodgkin's lymphoma, Kaposi's sarcoma and invasive cervical cancer have a higher incidence in persons with HIV infection and all three are AIDS-defining illnesses. In addition, several reports suggest that a number of other malignancies may occur at an increased incidence in persons with HIV infection, including squamous-cell carcinoma of the head, neck and anus, plasmacytoma, melanoma, small-cell lung cancer, basal-cell cancer, and germ-cell tumours. Clinicians should become familiar with HIV-related malignancies as their incidence is expected to further increase as more effective therapies for HIV and associated opportunistic infections allow patients to live longer in an advanced state of immunodeficiency. In the current article, we will review the clinical and therapeutic aspects of the most common AIDS-related malignancies including non-Hodgkin's and Hodgkin's lymphomas, Kaposi's sarcoma and anogenital epithelial neoplasias.

Abstract
Neoplasms are a common complication of HIV-infected individuals. The increased survival rates of those with HIV infection may allow the emergence of an increased number of cancers. The new therapeutic regimens may slow the rate of progression by partially restoring the integrity of the immune system.
