Incidence and Clinical Description of Lymphomas in Children and Adolescents with Vertical Transmission of HIV in Rio de Janeiro, Brazil, in Pre- and Post-Combined Antiretroviral Therapy Eras: A Multicentric Hospital-Based Survival Analysis Study. Cancers (Basel) 2022; 14:cancers14246129. [PMID: 36551614 PMCID: PMC9776495 DOI: 10.3390/cancers14246129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/25/2022] [Accepted: 12/06/2022] [Indexed: 12/15/2022] Open
Abstract
The incidence of cancer in children living with HIV (CLWH) is high and lymphomas are the most common type of cancer in this population. The combined antiretroviral therapy (cART) changed the natural history of HIV infection. To determine the incidence and profile of these CLWH malignancies in Rio de Janeiro (RJ), Brazil, we conducted a retrospective and observational study of vertically infected CLWH, ranging from 0−20 incomplete years, from 1995 to 2018, at five reference centers. The study period was divided into three eras in accordance with the widespread use of cART in Brazil. 1306 patients were included. Of the 25 lymphomas found, 19 were AIDS-defining malignancies (ADM); 6 were non-AIDS-defining malignancies (NADM). The incidence rate (IR) of lymphoma developing was 1.70 per 1000 children-year (95% CI 1.09−2.50). ADM development IR decreased from 2.09−1.75−0.19 per 1000 children-year (p < 0.001) through cART eras. Cumulative Nelson−Aalen hazards of developing ADM over a 20-year period were 3.73% in the Early-cART era, 3.07% in the Mid-cART era, and 0.32% in the Late-cART era (p = 0.013). This study demonstrates the IR of lymphoma in CLWH in RJ, Brazil, as well as the benefit of cART in reducing ADM and death occurrence in the Post-cART era.

Abstract
According to the joint United Nations Programme on HIV/AIDS (UNAIDS), 37.7 million adults and children worldwide were estimated to be living with HIV or acquired immune deficiency syndrome (AIDS) at the end of 2020 [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. Most reside in low- and middle-income countries, with approximately 67% in sub-Saharan Africa (SSA). At the end of 2020, the total number of children less than 15 years of age living with HIV infection was 2.6 million, of whom 2.3 million (88%) were living in SSA. Aggressive interventions have reduced the annual number of incident (new) HIV infections among children to around 150,000 [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. However, paediatric HIV infection remains a pandemic affecting children predominantly in SSA but is also seen in Asia and sporadically elsewhere particularly in areas of civil strife such as is currently the case in Ukraine [War in Ukraine. (2022). https://www.unaids.org/en/War-Ukraine-special . Accessed Apr 2022]. New HIV infections among children declined by more than half (54%) from 2010 to 2020, due mainly to the increased provision of antiretroviral therapy to pregnant and breastfeeding women living with HIV [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. These programmes include early identification of HIV infection in pregnant or breastfeeding women through routine HIV testing, provision of antiretroviral therapy (ART) to all HIV-infected women who are pregnant or breastfeeding, provision of antiretroviral prophylaxis to their newborn infants during the first 6-12 weeks of life, delivery by elective Caesarean section when indicated, promotion of exclusive breastfeeding, early infancy screening for HIV infection, and initiation of ART in infants with HIV infection. HIV-infected children may require surgery either as an emergency to deal with a life-threatening incidental condition unrelated to HIV infection or for a complication of the disease such as tuberculosis or an aggressive soft tissue infection like necrotising fasciitis. Non-emergency surgical procedures may be required to assist in the diagnosis of an HIV-related condition or to correct a routine surgical problem electively. Surgical conditions associated with HIV infection are described under categories of soft tissue or organ-specific infections requiring drainage or debridement; gastrointestinal tract disease and complications; infections in the perineal area; malignancies and HIV-associated vasculitis. Although surgical outcomes are less favourable in HIV-infected children, pre-operative treatment of coinfections, administration of cotrimoxazole prophylaxis, nutritional support and antiretroviral therapy, together with peri-operative antibiotic prophylaxis have resulted in excellent short-term outcomes [World Health Organization. Consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection: Recommendations for a public health approach, June 201 http://www.apps.who.int/iris/bitstream/10665/85321/1/9789241505727_eng.pdf?ua=1 ; World Health Organization Guideline on when to start antiretroviral therapy and on pre-exposure prophylaxis for HIV, September 2015. http://www.apps.who.int/iris/bitstream/10665/186275/1/9789241509565_eng.pdf?ua=1;Eley et al. in BMC Infect Dis 2:3, 2002;Karpelowsky et al. in Pediatr Surg Int 28:1007-1014, 2012;].

Abstract
Youth Living with HIV/AIDS (YLWHIV) have a higher risk of developing immunodeficiency related illnesses including certain cancers than their general population counterparts of the same age. This narrative review of current available literature describes factors associated with pediatric access to oncological services, and the role economic strengthening could play in improving health outcomes for this vulnerable population. Findings suggest that both HIV-infected and -uninfected children living in low and middle-income countries struggle with access and adherence to cancer treatment and care. Cost of treatment is a major barrier to access and adherence. Asset-building savings programs may increase financial security and subsequently result in better health outcomes although they have not been utilized to improve access to cancer treatment.

Abstract
Vivid descriptions of Kaposi sarcoma (KS) occurring in children and adolescents from central and eastern Africa originated over 50 years ago. Unique clinical characteristics of pediatric KS in Africa were well described within these geographic regions that were eventually understood to be endemic for human herpesvirus-8/Kaposi sarcoma herpesvirus (HHV-8/KSHV) infection, the causative agent of KS. Having catapulted in incidence with the HIV epidemic, KS is currently among the top five most common childhood cancers in numerous countries throughout the region. The main feature that differentiates the childhood form of KS from adult disease is clinical presentation with primarily bulging lymphadenopathy. This group of patients represents the most common clinical subtype of pediatric KS in KSHV-endemic regions. Lymphadenopathic KS in children is associated with other distinct features, such as sparse occurrence of prototypical hyperpigmented cutaneous lesions, frequent presentation with severe cytopenias and a normal CD4 count, and a fulminant clinical course if untreated with chemotherapy. Increased awareness and improved recognition of lymphadenopathic KS are critically important, particularly because this subset of patients typically experiences a favorable response to chemotherapy characterized by durable complete remission. Clinical phenotypes typically observed in adult KS also occur in children-mild/moderate disease limited to cutaneous and oral involvement, woody edema, and visceral disease. This review summarizes the heterogeneous patterns of disease presentation and treatment response observed among the divergent clinical phenotypes of pediatric KS, highlights additional KSHV-related malignancies, and explores some of the potential biological drivers of such clinical phenomena.

Abstract
The global experience with pediatric Kaposi sarcoma (KS) has evolved immensely since the onset of HIV (human immunodeficiency virus). In this review, current perspectives on childhood KS are discussed in the context of the HIV epidemic in sub-Saharan Africa. Endemic (HIV-unrelated) KS was first described over 50 years ago in central and eastern Africa, regions where human herpesvirus-8, the causative agent of KS, is endemic. With the alarming rise in HIV prevalence over the past few decades, KS has become not only the most common HIV-related malignancy in Africa, but also one of the most common overall childhood cancers throughout the central, eastern, and southern regions of the continent. The unique clinical features of pediatric KS that were described in those early endemic KS reports have been re-affirmed by the contemporary experience with HIV-related KS. These characteristics include a predilection for primary lymph node involvement, significant proportions of patients lacking prototypical cutaneous lesions, and the potential for fulminant disease progression. Other clinical features that distinguish childhood KS from adult disease include disease presentation with severe cytopenias, and the common occurrence of childhood KS without severe CD4 count suppression. Distinct clinical heterogeneity in disease presentation and treatment response have been demonstrated. Long-term complete remission and event-free survival can be achieved—especially in children with lymphadenopathic KS—utilizing treatment with antiretroviral therapy plus mild–moderate chemotherapy regimens that are well tolerated, even in low-income settings. A pediatric-specific staging classification and risk-stratification platform have been retrospectively validated, and may help guide therapeutic strategies. With expansion of the HIV treatment infrastructure throughout Africa, coupled with recent developments in establishing comprehensive pediatric oncology programs, there is great potential for improving outcomes for children with KS. Increased awareness of the unique clinical nuances and collaborative evaluations of pediatric-specific treatment paradigms are required to optimize survival for children with KS.

Abstract
The majority of African children with cancer die without access to resources. We describe efforts to build a public treatment program with curative intent for childhood cancer in Lilongwe, Malawi despite severe limitations in diagnostic and therapeutic resources. We retrospectively analyzed a cohort of childhood cancer patients at Kamuzu Central Hospital from 12/2011-6/2013. Consistently available chemotherapeutic agents were limited to cyclophosphamide, vincristine, doxorubicin, bleomycin, methotrexate, and prednisone. Of 258 newly diagnosed childhood malignancies, 17 patients with retinoblastoma were excluded from clinical analyses due to insufficient clinical data. Among the remainder of the cohort (n = 241), 42% were female with median age 8.4 years (range 0.6-17.9). Forty-six (19%) were HIV-infected (42 Kaposi sarcoma, 3 Burkitt lymphoma, 1 Hodgkin lymphoma). The most common clinical presentations were palpable abdominal mass (41%), peripheral lymphadenopathy (33%), and jaw mass (17%). Nearly two-thirds of total diagnoses were accounted for by Burkitt lymphoma (n = 74), Kaposi sarcoma (n = 52), Hodgkin lymphoma (n = 21), and Wilms tumor (n = 19). Twelve-month overall survival for these 4 most common diagnoses was 54% (95% confidence interval 46-61) versus 19% (95% confidence interval 11-30) for all other diagnoses (median follow-up 19 months). Treatment-related mortality was highest in patients with non-Wilms solid tumors of the abdomen (48% versus 10% for the overall cohort, p < 0.001), while treatment abandonment was highest in patients with bone and soft-tissue sarcomas (29% versus 14% overall, p = 0.05). Childhood cancers with excellent curative potential accounted for the majority of patients, establishing an opportunity to build treatment programs with curative intent despite severe limitations.

Abstract
Background. Although Burkitt lymphoma (BL) is the most common childhood lymphoma in sub-Saharan Africa, Hodgkin lymphoma (HL) and other non-Hodgkin lymphomas occur. Diagnosing non-jaw mass presentations is challenging with limited pathology resources. Procedure. We retrospectively analyzed 114 pediatric lymphomas in Lilongwe, Malawi, from December 2011 to June 2013 and compared clinical versus pathology-based diagnoses over two time periods. Access to pathology resources became more consistent in 2013 compared with 2011-2012; pathology interpretations were based on morphology only. Results. Median age was 8.4 years (2.1-16.3). The most common anatomical sites of presentation were palpable abdominal mass 51%, peripheral lymphadenopathy 35%, and jaw mass 34%. There were 51% jaw masses among clinical diagnoses versus 11% in the pathology-based group (P < .01), whereas 62% of pathology diagnoses involved peripheral lymphadenopathy versus 16% in the clinical group (P < .01). The breakdown of clinical diagnoses included BL 85%, lymphoblastic lymphoma (LBL) 9%, HL 4%, and diffuse large B-cell lymphoma (DLBCL) 1%, whereas pathology-based diagnoses included HL 38%, BL 36%, LBL 15%, and DLBCL 11% (P < .01). Lymphoma diagnosis was pathology confirmed in 19/66 patients (29%) in 2011-2012 and 28/48 (60%) in 2013 (P < .01). The percentage of non-BL diagnoses was consistent across time periods (35%); however, 14/23 (61%) non-BL diagnoses were pathology confirmed in 2011-2012 versus 16/17 (94%) in 2013. Conclusions. Lymphomas other than Burkitt accounted for 35% of childhood lymphoma diagnoses. Over-reliance on clinical diagnosis for BL was a limitation, but confidence in non-BL diagnoses improved with time as pathology confirmation became standard. Increased awareness of non-BL lymphomas in equatorial Africa is warranted.

Abstract
BACKGROUND With improved survival in children living with human immunodeficiency virus (HIV) infection (CLHIV), malignancies are being increasingly recognized. PATIENTS AND METHODS Among the CLHIV registered at our institute from January 1994 to March 2015, children with malignancy were analysed in detail. RESULTS In total, 734 children affected by HIV were registered. Out of these, 11 children (9 boys, 2 girls) were diagnosed to have malignancy. Malignancy was the presenting feature of HIV infection in 4 children. High-grade non-Hodgkin lymphoma (NHL) was the most common malignancy noted in 9 of 11 (81%) children, whereas the remaining 2 children had Hodgkin's lymphoma. Survival in our cohort was 80% among children in whom chemotherapy was initiated, and overall survival was 36% (4 of 11 children). CONCLUSION NHL was the most common malignancy in CLHIV in our cohort. Low-conditioning chemotherapy protocols along with initiation of anti-retroviral therapy resulted in improved outcomes in CLHIV with malignancy.

Abstract
Context and Aim: Data on HIV associated hematologic malignancies is sparse from India. This study attempts to analyze the spectrum and features of this disease at a tertiary cancer center in India. Setting and Methods: Retrospective study from case records of patients registered with a diagnosis of hematologic malignancy and HIV infection between January 2010 and June 2015. Results: Thirteen cases of HIV associated hematologic malignancies were identified, six of them pediatric. HIV diagnosis was concurrent to diagnosis of cancer in 12 and preceded it in one of them. ECOG PS at presentation was >1 in all of them. All patients, except one, had B symptoms. Six of the patients had bulky disease and six are stage 4. Predominant extranodal disease was seen in 67% of them. NHL accounted for 10 of 13 patients and DLBCL-Germinal center was the most common subtype. Mean CD4+ cell count was 235/μL (range, 32-494). HAART could be given along with chemotherapy to 11 patients. Two-thirds of patients received standard doses of therapy. Chemo-toxicity required hospitalization in 58%. CR was achieved in 45% and 36% had progressive disease with first-line therapy. At the time of last follow up, 3 patients were alive with responsive disease, 2 in CR and 1 in PR. None of the pediatric patients were long time responders. Conclusions: These malignancies were of advanced stage and higher grade. Goal of therapy, in the HAART era, is curative. Pediatric patients had dismal outcome despite good chemotherapy and HAART. There is an urgent need to improve data collection for HIV related cancers in India.

Abstract
We report the case of a perinatally HIV-1-infected child, previously immunologically unresponsive to antiretroviral treatments (including the highly active antiretroviral therapy), who instead developed a vigorous and long-lasting immune response after the highly active antiretroviral therapy was associated with antineoplastic chemotherapy undertaken for a B-cell non-Hodgkin bone lymphoma.

Abstract
BACKGROUND Little is known on the risk of cancer in HIV-positive children in sub-Saharan Africa. We examined incidence and risk factors of AIDS-defining and other cancers in pediatric antiretroviral therapy (ART) programs in South Africa. METHODS We linked the records of 5 ART programs in Johannesburg and Cape Town to those of pediatric oncology units, based on name and surname, date of birth, folder and civil identification numbers. We calculated incidence rates and obtained hazard ratios (HR) with 95% confidence intervals (CI) from Cox regression models including ART, sex, age and degree of immunodeficiency. Missing CD4 counts and CD4% were multiply imputed. Immunodeficiency was defined according to World Health Organization 2005 criteria. RESULTS Data of 11,707 HIV-positive children were included in the analysis. During 29,348 person-years of follow-up 24 cancers were diagnosed, for an incidence rate of 82 per 100,000 person-years (95% CI: 55-122). The most frequent cancers were Kaposi sarcoma (34 per 100,000 person-years) and non-Hodgkin Lymphoma (31 per 100,000 person-years). The incidence of non AIDS-defining malignancies was 17 per 100,000. The risk of developing cancer was lower on ART (HR: 0.29; 95% CI: 0.09-0.86), and increased with age at enrollment (>10 vs. <3 years: HR: 7.3; 95% CI: 2.2-24.6) and immunodeficiency at enrollment (advanced/severe versus no/mild: HR: 3.5; 95% CI: 1.1-12.0). The HR for the effect of ART from complete case analysis was similar but ceased to be statistically significant (P = 0.078). CONCLUSIONS Early HIV diagnosis and linkage to care, with start of ART before advanced immunodeficiency develops, may substantially reduce the burden of cancer in HIV-positive children in South Africa and elsewhere.

Abstract
Kaposi sarcoma (KS) is the most common HIV-associated malignancy in children and adolescents in Africa. Pediatric KS is distinct from adult disease. We evaluated the clinical characteristics associated with long-term outcomes. We performed a retrospective observational analysis of 70 HIV-infected children and adolescents with KS less than 18 years of age diagnosed between 8/2010 and 6/2013 in Lilongwe, Malawi. Local first-line treatment included bleomycin and vincristine plus nevirapine-based highly active anti-retroviral therapy (HAART). Median age was 8.6 years (range 1.7–17.9); there were 35 females (50%). Most common sites of presentation were: lymph node (74%), skin (59%), subcutaneous nodules (33%), oral (27%), woody edema (24%), and visceral (16%). Eighteen (26%) presented with lymphadenopathy only. Severe CD4 suppression occurred in 28%. At time of KS diagnosis, 49% were already on HAART. Overall, 28% presented with a platelet count < 100 x 109/L and 37% with hemoglobin < 8 g/dL. The 2-year event-free (EFS) and overall survival (OS) were 46% and 58% respectively (median follow-up 29 months, range 15–50). Multivariable analysis of risk of death and failure to achieve EFS demonstrated that visceral disease (odds ratios [OR] 19.08 and 11.61, 95% CI 2.22–163.90 and 1.60–83.95 respectively) and presenting with more than 20 skin/oral lesions (OR 9.57 and 22.90, 95% CI 1.01–90.99 and 1.00–524.13 respectively) were independent risk factors for both. Woody edema was associated with failure to achieve EFS (OR 7.80, 95% CI 1.84–33.08) but not death. Univariable analysis revealed that lymph node involvement was favorable for EFS (OR 0.28, 95% CI 0.08–0.99), while T1 TIS staging criteria, presence of cytopenias, and severe immune suppression were not associated with increased mortality. Long-term complete remission is achievable in pediatric KS, however outcomes vary according to clinical presentation. Based on clinical heterogeneity, treatment according to risk-stratification is necessary to improve overall outcomes.

Abstract
SUMMARY Systematic studies comparing the outcomes of cancer treatment between children with and without HIV are scarce. The literature seems to suggest that, even with present therapeutic advances, prognosis is poor with HIV infection. The aim of this Review was to assess scientific publications from 1990 to present, addressing the difficulties associated with treatment of cancer in children with AIDS and the adaptive changes in therapy. Although much progress has been achieved, further research is needed about antiretroviral and cytotoxic drug interactions, the optimum use of supportive therapy including stem cells and bone marrow transplant, the timing of the initiation of highly active antiretroviral therapy, and the optimum use of protease inhibitors.

Abstract
Chronic HIV infection leads to increased risk of non-Hodgkin B-cell lymphoma. However, only few recent data are available about their current management and prognosis in HIV-infected children since the advent highly active antiretroviral therapy (HAART). This multicenter retrospective study describes the 12 cases of B-cell non-Hodgkin lymphoma diagnosed in HIV-infected children in France between 1996 and 2009. All children had moderate to severe immunosuppression and high viral load at the time of diagnosis. Nine children had extracerebral primary sites and 3 had a primary central nervous system lymphoma. Eight patients had Burkitt lymphoma; 4 had diffuse large B-cell lymphoma. Concomitantly with HAART, all children with extracerebral lymphoma received intensive chemotherapy according to LMB protocol, those with primary central nervous system lymphoma received high-dose methotrexate. No toxicity-related deaths occurred. Ten patients entered complete remission (CR), 2 died of tumor progression despite a second line of therapy. No relapses occurred after CR (median follow-up, 72 mo). Thus, prognosis of patients unresponsive to first-line lymphoma treatment remains poor, but relapse seems to be rare when CR is achieved. Children without severe comorbidities can tolerate intensive chemotherapy with a mandatory HAART treatment, taking into account drug interactions.

Abstract
Pediatric HIV (human immunodeficiency virus) is a pandemic predominantly in sub-Saharan Africa. Approximately 2.2 million children aged less than 15 years are infected with HIV, representing almost 95% of the total number of children globally infected with HIV. Therefore, increasing numbers of HIVi or -exposed but uninfected children can be expected to require a surgical procedure to assist in the diagnosis of an HIV/acquired immune deficiency syndrome-related complication, to address a life-threatening complication of the disease, or for routine surgery encountered in HIV-unexposed children. HIVi children may present with both conditions unique to HIV infection and surgical conditions routine in pediatric surgical practice. HIV exposure confers an increased risk of complications and mortality for all children after surgery, whether they are HIV infected or not. This risk of complications is higher in the HIVi group of patients. These findings seem to be independent of whether patients undergo an elective or emergency procedure, but the risk of an adverse outcome is higher for a major procedure. Surgical implications of HIV infection are comprehensively reviewed in this article.

Abstract
Mitochondrial compromise has been documented in infants born to women infected with the human immunodeficiency virus (HIV-1) who received nucleoside reverse transcriptase inhibitor (NRTI) therapy during pregnancy. To model these human exposures, we examined mitochondrial integrity at birth and 1 year in brain cortex and liver from offspring of retroviral-free Erythrocebus patas dams-administered human-equivalent NRTI doses for the last half (10 weeks) of gestation. Additional infants, followed for 1 year, were given the same drugs as their mothers for the first 6 weeks of life. Exposures included: no drug, Zidovudine (AZT), Lamivudine (3TC), AZT/3TC, AZT/Didanosine (ddI), and Stavudine (d4T)/3TC. In brain and liver, oxidative phosphorylation (OXPHOS) enzyme activities (complexes I, II, and IV) showed minimal differences between unexposed and NRTI-exposed offspring at both times. Brain and liver mitochondria from most NRTI-exposed patas, both at birth and 1 year of age, contained significant (p < 0.05) morphological damage observed by electron microscopy (EM), based on scoring of coded photomicrographs. Brain and liver mitochondrial DNA (mtDNA) levels in NRTI-exposed patas were depleted significantly in the 3TC and d4T/3TC groups at birth and were depleted significantly (p < 0.05) at 1 year in all NRTI-exposed groups. In 1-year-old infants exposed in utero to NRTIs, mtDNA depletion was 28.8-51.8% in brain and 37.4-56.5% in liver. These investigations suggest that some NRTI-exposed human infants may sustain similar mitochondrial compromise in brain and liver and should be followed long term for cognitive integrity and liver function.

Abstract
BACKGROUND The impact of infection with HIV on the risk of cancer in children is uncertain, particularly for those living in sub-Saharan Africa. In an ongoing study in a paediatric oncology centre in Malawi, children (aged = 15 years) with known or suspected cancers are being recruited and tested for HIV and their mothers or carers interviewed. This study reports findings for children recruited between 2005 and 2008. METHODS Only children with a cancer diagnosis were included. Odds ratios (OR) for being HIV positive were estimated for each cancer type (with adjustment for age (<5 years, >/= 5 years) and sex) using children with other cancers and non-malignant conditions as a comparison group (excluding the known HIV-associated cancers, Kaposi sarcoma and lymphomas, as well as children with other haematological malignancies or with confirmed non-cancer diagnoses). RESULTS Of the 586 children recruited, 541 (92%) met the inclusion criteria and 525 (97%) were tested for HIV. Overall HIV seroprevalence was 10%. Infection with HIV was associated with Kaposi sarcoma (29 cases; OR = 93.5, 95% CI 26.9 to 324.4) and with non-Burkitt, non-Hodgkin lymphoma (33 cases; OR = 4.4, 95% CI 1.1 to 17.9) but not with Burkitt lymphoma (269 cases; OR = 2.2, 95% CI 0.8 to 6.4). CONCLUSIONS In this study, only Kaposi sarcoma and non-Burkitt, non-Hodgkin lymphoma were associated with HIV infection. The endemic form of Burkitt lymphoma, which is relatively frequent in Malawi, was not significantly associated with HIV. While the relatively small numbers of children with other cancers, together with possible limitations of diagnostic testing may limit our conclusions, the findings may suggest differences in the pathogenesis of HIV-related malignancies in different parts of the world.

Abstract
HIV infection predisposes to cancer during childhood. In addition to the AIDS-defining non-Hodgkin lymphoma (NHL) and Kaposi sarcoma, a range of other lymphoid malignancies and solid tumors have been described. We report the first case of an HIV-positive child with thymic carcinoma in the setting of regressing thymic cysts. The tumor expressed CKIT but failed to respond to imatinab mesylate after a transient response to multiagent chemotherapy. This case extends the spectrum of pediatric malignancy in the setting of HIV and suggests that patients with presumed benign thymic cysts require ongoing surveillance.

Abstract
In contrast to adults, autologous stem cell transplantation (ASCT) as part of the salvage strategy after high-dose chemo/radiotherapy in human immunodeficiency virus (HIV) related Non-Hodgkin lymphoma (NHL) is not yet established for children. We report on a 13-year patient with congenital HIV infection and refractory Burkitt lymphoma, who was successfully treated by high-dose therapy (HDT) including rituximab followed by ASCT. After 26 months follow-up the patient remains in complete remission and his HIV parameters have normalized with continued highly active antiretroviral therapy (HAART). HIV infection may no longer exclude children from ASCT as part of salvage therapy.

Abstract
BACKGROUND Data on childhood cancers in Africa are sparse, particularly since the spread of HIV. We aimed to document the frequency of pediatric cancers presenting to a large central hospital in Malawi, detailing the presenting features, initial investigations, and HIV status of these children. PROCEDURE A retrospective audit of the spectrum and clinical presentation of cancers among children (<16 years) seen at Queen Elizabeth's Central Hospital (QECH), between 1998 and 2003. RESULTS Seven hundred seven children with cancer were seen, the number of cases per year increased over the time period; 50% (351) had Burkitt lymphoma, 13% (89) had retinoblastoma, and 9% (61) had Kaposi sarcoma, with a variety of other tumors comprising the remainder. Kaposi sarcoma markedly increased in frequency over time. Histological verification of diagnosis was available for 49% (348). The proportion of children with cancer who were tested for HIV increased over time, but varied by cancer type. Amongst those tested, the seroprevalence was 93% (52/56) for children with Kaposi sarcoma, 4% (11/289) for those with Burkitt lymphoma, 31% (8/26) for those with other non-Hodgkin lymphomas, 7% (1/15) for those with Hodgkin disease, and 5% (5/103) for those with other cancers. CONCLUSIONS The number of cases seen per year has increased over the study period for almost all cancers, but in particular for Kaposi sarcoma. Burkitt lymphoma remains the commonest pediatric tumor in Malawi. In the case of Burkitt lymphoma, non-Hodgkin lymphoma, and Kaposi sarcoma there is a significant difference in the presentation of HIV-seropositive and -seronegative children.

Abstract
Cancer in children is rare and accounts for about 1% of all malignancies. In the developed world, however, it is the commonest cause of disease-related deaths in childhood, carrying with it a great economic and emotional cost. Cancers are assumed to be multivariate, multifactorial diseases that occur when a complex and prolonged process involving genetic and environmental factors interact in a multistage sequence. This article explores the available evidence for this process, primarily from the environmental linkages perspective but including some evidence of the genetic factors.

Abstract
PURPOSE To evaluate the impact of highly active antiretroviral therapy (HAART) on cancer incidence in HIV-infected children throughout a 20-year period. PATIENTS AND METHODS An observational population study was conducted on 1,190 perinatally HIV-infected children enrolled onto the Italian Register for HIV Infection in Children from 1985 to 2004 and never lost to follow-up (total observation time, 10,037.66 years). Cancer rates were calculated in the pre-HAART (1985 to 1995), early HAART (1996 to 1999), and late HAART (2000 to 2004) periods and compared using Poisson regression adjusted for age. The proportion of HAART-treated children increased from 4.1% in 1996 to 60.4% in 1999 and to 81.5% in 2004. In the same time frame, the proportion of children receiving HAART for at least 2 years increased from 3.1% to 77.0%. RESULTS Overall, 35 cancers occurred. Cancer rates were 4.49 (95% CI, 2.37 to 6.64), 4.09 (95% CI, 1.68 to 6.50), and 0.76 (95% CI, 0.00 to 1.80) per 1,000 children per year in 1985 to 1995, 1996 to 1999, and 2000 to 2004, respectively. Notably, there was no significant difference comparing the periods from 1985 to 1995 and 1996 to 1999 (P = .081). By contrast, cancer rates were significantly lower in the period from 2000 to 2004 than in 1996 to 1999 (P < .0001). Results were confirmed by separately analyzing data from children observed from birth (P = .418 for 1985 to 1995 v 1996 to 1999; P = .001 for 1996 to 1999 v 2000 to 2004). CONCLUSION Dramatically reduced cancer rates were observed only in the late HAART period in parallel to the increasing proportion of children receiving HAART therapy.

Abstract
This population-based study is based on 5802 cases of soft tissue sarcomas (STS) in children aged 0-14 years extracted from the database of the Automated Childhood Cancer Information System (ACCIS) and registered in population-based cancer registries in Europe for the period 1978-1997. STS represent almost 8% of neoplasms in children, almost half of whom are less than 5 years at diagnosis. Rhabdomyosarcoma is the most frequent childhood STS (50%). During 1988-1997 the age-standardised incidence of STS in Europe was 9.1 per million children, lowest in the West and East and highest in the North. The incidence of STS increased almost 2% per year over the period 1978-1997, attributable mostly to increase in genito-urinary rhabdomyosarcoma. Prognosis of children with STS was related to age and site of tumour. Five-year survival of children with STS increased from 46% in 1978-1977 to 66% in 1993-1997, reaching 74% in the North for those diagnosed in 1993-1997. This improvement is ascribed to therapy advances.

Abstract
We report a case of successful treatment of advanced Burkitt lymphoma in a 3-year-old girl with congenitally acquired HIV infection. She was treated with intensive chemotherapy combined with highly active anti-retroviral therapy (HAART). She had not received any anti-retroviral therapy and had stage C3 HIV infection on admission. She was treated with modified BFM 90 and remission was achieved. Simultaneously with chemotherapy, HAART with three drugs was carried out, resulting in improvements in HIV parameters. Our report suggests chemotherapy combined with HAART is feasible in children and may favorably change the outcomes in pediatric patients with AIDS-NHL.

Abstract
To determine the incidence and spectrum of malignancies in human immunodeficiency virus-infected children, we surveyed 48 hospitals in Thailand between 1996 and 2000. There were 23 children (14 boys and 9 girls; average age at diagnosis of malignancy, 4.2 years), and the incidence rate was 0.6 per 1000 person-years. The most common malignancy was lymphoma (87.0%). The prognosis was poor.

Abstract
OBJECTIVES To determine the incidence of and factors associated with malignancy in perinatally human immunodeficiency virus (HIV)-infected children in the United States. METHODS Included were 2969 children followed in the Pediatric AIDS Clinical Trials Group (PACTG) 219/219C cohort from 1993 through 2003. Cancer incidence by sex, race, age, histology and highly active antiretroviral therapy (HAART) era (pre-HAART, 1993-1997; HAART, 1998-2003) was estimated, and the standardized incidence ratio contrasting infected and uninfected children was determined. Poisson regression was used to further investigate the relation between HAART use (> or =3 drugs of > or =2 classes, 1 of which was a protease inhibitor), CD4% and cancer. RESULTS There were 37 cancers (17 prevalent and 20 incident) diagnosed in 2969 children for a prevalence of 0.6% [95% confidence interval (CI), 0.3, 0.9] and an incidence of 1.56/1000 person-years (95% CI 0.95, 2.41). Compared with uninfected children, the standardized incidence ratio was 10.08 (95% CI 5.87, 16.14). Incidence did not significantly differ by sex, race, age or HAART era. Of the cases, 35% were immunocompetent (CD4 > or =25%), 25% were moderately immunosuppressed (15%< or = CD4 < or =24%) and 40% were severely immunosuppressed (CD4 <15%) at diagnosis. In multivariate regression, the cancer rate was 3.09 (95% CI 1.22, 7.85) times higher in children with < or =2 years of HAART use than in children with >2 years of HAART and 3.20 (95% CI 1.32, 7.76) times higher in children with CD4 <15% at cohort enrollment than in children with CD4 > or =15%. CONCLUSION Cancer incidence in this U.S. pediatric cohort was lower than that of European cohorts but was markedly higher than that of HIV-uninfected children. Cancer incidence was highest in children who were severely immunosuppressed and in children who received HAART for < or =2 years.

Abstract
OBJECTIVE Although most uninfected infants born to women infected with HIV-1 show no clinical evidence of mitochondrial compromise, mitochondrial dysfunction has been reported in children born to women receiving zidovudine and/or lamivudine during pregnancy. In this pilot study we examined mitochondrial integrity in HIV-1-uninfected infants born to HIV-1-infected women receiving Combivir during pregnancy. DESIGN : Samples of umbilical cord and cord blood were obtained from HIV-1-uninfected infants born to either HIV-1-infected women receiving Combivir therapy during pregnancy (n = 10) or HIV-1-uninfected women (n = 9). METHODS Mitochondrial morphological integrity was examined in umbilical cords (n = 16) by electron microscopy and mtDNA quantity was determined in DNA from cord blood (n = 18) and umbilical cord (n = 18) by PCR-chemiluminescence immunoassay detection. RESULTS In umbilical cords from six of nine infants born to HIV-1-infected mothers taking Combivir moderate to severe mitochondrial morphological damage was observed (P = 0.011), while none of seven unexposed infants showed similar damage. Compared to unexposed infants, statistically significant mtDNA depletion was observed in umbilical cord (P = 0.006) and cord blood (P = 0.003) from drug-exposed infants. CONCLUSIONS A cohort of HIV-1-uninfected Combivir-exposed infants with no clinical symptoms showed morphological and molecular evidence of mitochondrial damage.

Abstract
Although children born to HIV-infected (HIV+) women receiving antiretroviral therapy during pregnancy show virtually no adverse clinical effects at birth, the antiretroviral nucleoside analog drugs are known to damage nuclear and mitochondrial DNA. In this study, biomarkers of mitochondrial toxicity and genotoxicity have been examined in a well-characterized sample set consisting of infants born to HIV-uninfected (HIV-) mothers (n = 30), and HIV- infants (n = 20) born to HIV-infected (HIV+) mothers who received either no antiretroviral therapy (n = 10) or zidovudine (3'-azido-3'-deoxythymidine [AZT]) during pregnancy (n = 10). DNA from cord blood leukocytes and peripheral blood leukocytes taken at 1 and 2 years of age was examined for loss of mitochondrial DNA (mtDNA) and telomere integrity. Telomere length, a measure of nuclear DNA damage, was the same in all infants at birth and at age 1 year. The quantity of mtDNA was assessed relative to nuclear DNA using a polymerase chain reaction-based chemiluminescence detection (PCR-CID) method that determined mitochondrial D Loop gene copies relative to nuclear 18S RNA gene copies by comparison with a standard curve. MtDNA quantity was expressed as a ratio of gene copy numbers. In infants of uninfected mothers (AZT-/HIV-) at the three time points, the ratios were 442 to 515, whereas in infants of untreated AZT-/HIV+ mothers the ratios were 261 to 297, and in infants of AZT-treated (AZT+/HIV+) mothers the ratios were 146 to 203. At all three time points, differences between the AZT-/HIV- group and the two HIV+ groups were statistically significant (p <.05), and differences between the AZT-/HIV+ and AZT+/HIV+ groups were also statistically significant (p <.05), demonstrating that AZT exposure causes a persistent depletion of mtDNA. The study shows that children of HIV+ mothers are at risk for mitochondrial damage that is further increased in infants of mothers receiving AZT during pregnancy.

Abstract
Non-Hodgkin's lymphomas are the most common cancers in children with human immunodeficiency virus (HIV) infection. Extranodal disease is the most common form of clinical presentation. Treatment with aggressive chemotherapy and highly active antiretroviral therapy has improved the prognosis of these children. We present a 10-year-old severely immunocompromised girl with HIV infection and non-Hodgkin's lymphoma manifested by a muscle mass.

Abstract
Childhood non-Hodgkin's lymphomas, including Burkitt and Burkitt-like, are rarely diagnosed in infants. A case of B-cell lymphoma in a 13-month-old girl with extensive abdominal disease, ascites, pleural effusion, and tumor lysis syndrome is reported. Phenotypic analysis showed a germinal center B-cell phenotype, and a B-cell clonality was confirmed by polymerase chain reaction. There was no evidence of Epstein-Barr and HIV infection. The case herein reported emphasizes the need for considering the diagnosis of lymphoma even in very young children.
