Efficacy of chemotherapeutics in classic and non-classic Kaposi sarcoma: A single-center retrospective real-world data.

Kaposi sarcoma is a rare disease and there is a gap in the literature about which chemotherapeutics should be applied, especially for the classical type. We aimed to present our institutional data on the demographic characteristics, treatment, and treatment efficacy in 16 Kaposi sarcoma (KS) patients treated with chemotherapy. We retrospectively analyzed the demographic and clinical characteristics, and the chemotherapeutic agents administered to the 16 KS patients diagnosed in our center and treated with chemotherapy, based on the medical records obtained. The median age, gender, type of KS, site of involvement, cytotoxic agents administered, progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety profiles of the patients were evaluated. The median age at disease onset was 61.07 years (range, 39.4-85.8 years). Among the patients, 1 had immunosuppression-related KS, 4 had AIDS-related KS, and 11 had classical KS. In the first-line cytotoxic therapy, 7 patients received pegylated-liposomal doxorubicin (PLD), 6 patients received paclitaxel, 2 patients received oral etoposide, and 1 patient received the adriamycin, bleomycin, and vincristine regimen. In the Kaplan-Meier analysis, the PFS was 39.9 months (95% CI, 7.7-72.0). In the first-line setting, a significant difference in terms of PFS was observed between the PLD- and paclitaxel-treated groups (not reached vs. 12.8 months, p = 0.033). The OS was 66.1 months (95% CI, 30.2-102.0). The ORR of the 16 patients was 43.8%, and their DCR was 81.3%. No grade 3 or 4 toxicity was observed. This retrospective study showed that PLD seems better than paclitaxel in terms of PFS and response rates and it has shown to have a good safety profile in KS patients.

Kaposi sarcoma incidence, survival and trends: Data from the information network on rare cancers in Europe (RARECAREnet).

BACKGROUND: This study provides updated information on Kaposi sarcoma (KS) in Europe during 1995-2007 from the RARECARENet project. METHODS: Data comes from 59 population-based cancer registries in 22 countries. KS was defined as ICD-O-3 morphology code 9140 combined with any topography code. Crude and age-adjusted incidence rates and relative survival for years of diagnosis 2000-2007 and with trends during 1995-2007 were calculated overall, by age and by country. RESULTS: The crude annual incidence rate was 0.28 per 100,000 and age-adjusted incidence was 0.23 per 100,000; incidence increased with age, from 0.18/100,000 at age 0-44 to 0.25/100,000 at age 45-64 and 0.69/100,000 at age 65 and over. Age-adjusted incidence in males was more than four times that in females. Portugal, which had the highest incidence of AIDS in Europe, had by far the highest incidence of KS at age 0-44, 1.44/100,000, more than four times the rate in any other country. Incidence among males in Europe aged 0-44 fell significantly between 1995-1998 and 1999-2002, followed by a significant increase in 2003-2007. Younger patients, with predominantly AIDS-related KS, formerly had a worse prognosis, but since 1999-2001 5-year relative survival increased for patients aged under 65, and by 2005-2007 was 83-86 % for all three age groups 0-44, 45-64, and 65 and over. CONCLUSION: Survival and quality of life for the increasing number of people in Europe affected by KS should improve further following the development of evidence-based guidelines for its management. Population-based cancer registries will continue to play a vital role in monitoring the burden of KS and improvements in its outcome.

Admitted AIDS-associated Kaposi sarcoma patients: Indications for admission and predictors of mortality.

Kaposi sarcoma (KS) is an AIDS-defining angioproliferative malignancy associated with high morbidity and mortality. Most KS patients in regions with high incidence such as sub-Saharan Africa present late with advanced stage disease. Admitted KS patients have high mortality rates. Factors associated with mortality of admitted KS patients are poorly defined.We conducted a retrospective file review to ascertain reasons for admission and identify factors associated with mortality of admitted HIV-associated (epidemic) KS patients in Zambia. Baseline study variables were collected, and patients were retrospectively followed from admission to time of discharge or death.Mortality rate for admitted epidemic KS patients was high at 20%. The most common reasons for admission included advanced KS disease, severe anemia, respiratory tract infections, and sepsis. The majority (48%) of admitted patients had advanced clinical stage with visceral involvement on admission. Clinical predictors of mortality on univariate analysis included visceral KS [odds ratio (OR) = 13.74; 95% confidence interval (95% CI) = 1.68-113; P = 0.02), fever (OR = 26; 95% CI = 4.85-139; P = .001), and sepsis (OR = 35.56; 95% CI = 6.05-209; P = .001). Baseline hemoglobin levels (5.6 vs 8.2 g/dL; P = .001) and baseline platelet counts (63 x 10^9/L vs 205 x 10^9/L; P = .01) were significantly lower in mortalities vs discharges. Baseline white cell counts were higher in mortalities vs discharges (13.78 x 10^9/L vs 5.58 x 10^9/L; P = .01), and HIV-1 viral loads at the time of admission were higher in mortalities vs discharges (47,607 vs 40 copies/µL; P = .02). However, only sepsis (or signs and symptoms of sepsis) were independently associated with mortality after controlling for confounders.In conclusion, common reasons for admission of epidemic KS patients include advanced disease, severe anemia, respiratory tract infections, and signs and symptoms of sepsis. Signs and symptoms of sepsis are independent predictors of mortality in these patients.

Treatment of advanced AIDS-associated Kaposi sarcoma in resource-limited settings: a three-arm, open-label, randomised, non-inferiority trial.

BACKGROUND: Optimal treatment regimens for AIDS-associated Kaposi sarcoma, a frequent contributor to morbidity and mortality among people with HIV, have not been systematically evaluated in low-income and middle-income countries, where the disease is most common. In this study, we aimed to investigate optimal treatment strategies for advanced stage disease in areas of high prevalence and limited resources. METHODS: In this open-label, non-inferiority trial, we enrolled people with HIV and advanced stage AIDS-associated Kaposi sarcoma attending 11 AIDS Clinical Trials Group sites in Brazil, Kenya, Malawi, South Africa, Uganda, and Zimbabwe. Eligible participants were randomly assigned (1:1:1) with a centralised computer system to receive either intravenous bleomycin and vincristine or oral etoposide (the investigational arms), or intravenous paclitaxel (the control arm), together with antiretroviral therapy (ART; combined efavirenz, tenofovir disoproxil fumarate, and emtricitabine). The primary outcome was progression-free survival (PFS) at week 48, using a 15% non-inferiority margin to compare the investigational groups against the active control group. Safety was assessed in all eligible treated study participants. The study was registered with ClinicalTrials.gov, NCT01435018. FINDINGS: 334 participants were enrolled between Oct 1, 2013, and March 8, 2018, when the study was closed early due to inferiority of the bleomycin and vincristine plus ART arm, as per the recommendations of the Data and Safety Monitoring Board (DSMB). The etoposide plus ART arm also closed due to inferiority in March, 2016, following a DSMB recommendation. Week-48 PFS rates were higher in the paclitaxel plus ART arm than in both investigational arms. The absolute differences in PFS were -30% (95% CI -52 to -8) for the comparison of paclitaxel plus ART (week 48 PFS 50%, 32 to 67; n=59) and etoposide plus ART (20%, 6 to 33; n=59), and -20% (-33% to -7%) for the comparison of paclitaxel plus ART (64%, 55 to 73; n=138) and bleomycin and vincristine plus ART (44%, 35 to 53; n=132). Both CIs overlapped the non-inferiority margin. The most common adverse events, in 329 eligible participants who began treatment, were neutropenia (48 [15%]), low serum albumin (33 [10%]), weight loss (29 [9%]), and anaemia (28 [9%]), occurring at similar frequency across treatment arms. INTERPRETATION: Non-inferiority of either investigational intervention was not shown, with paclitaxel plus ART showing superiority to both oral etoposide plus ART and bleomycin and vincristine plus ART, supporting its use in treating advanced AIDS-associated Kaposi sarcoma in resource-limited settings.

The Contribution of Kaposi's Sarcoma-Associated Herpesvirus to Mortality in Hospitalized Human Immunodeficiency Virus-Infected Patients Being Investigated for Tuberculosis in South Africa.

BACKGROUND: Despite increasing numbers of human immunodeficiency virus (HIV)-infected South Africans receiving antiretroviral therapy (ART), tuberculosis (TB) remains the leading cause of mortality. Approximately 25% of patients treated for TB have microbiologically unconfirmed diagnoses. We assessed whether elevated Kaposi's sarcoma-associated herpesvirus (KSHV) viral load (VL) contributes to mortality in hospitalized HIV-infected patients investigated for TB. METHODS: Six hundred eighty-two HIV-infected patients admitted to Khayelitsha Hospital, South Africa, were recruited, investigated for TB, and followed for 12 weeks. KSHV serostatus, peripheral blood KSHV-VL, and KSHV-associated clinical correlates were evaluated. RESULTS: Median CD4 count was 62 (range, 0-526) cells/µL; KSHV seropositivity was 30.7% (95% confidence interval [CI], 27%-34%); 5.8% had detectable KSHV-VL (median, 199.1 [range, 13.4-2.2 × 106] copies/106 cells); 22% died. Elevated KSHV-VL was associated with mortality (adjusted odds ratio, 6.5 [95% CI, 1.3-32.4]) in patients without TB or other microbiologically confirmed coinfections (n = 159). Six patients had "possible KSHV-inflammatory cytokine syndrome" (KICS): 5 died, representing significantly worse survival (P < .0001), and 1 patient was diagnosed with KSHV-associated multicentric Castleman disease at autopsy. CONCLUSIONS: Given the association of mortality with elevated KSHV-VL in critically ill HIV-infected patients with suspected but not microbiologically confirmed TB, KSHV-VL and KICS criteria may guide diagnostic and therapeutic evaluation.

A Reappraisal of Sex-Specific Cancer Survival Trends Among Adolescents and Young Adults in the United States.

BACKGROUND: Cancer survival among adolescents and young adults (AYAs) was previously reported as showing little or no improvement compared to younger or older counterparts. The role of the HIV/AIDS epidemic in the AYA survival deficit has not been evaluated. METHODS: Using cancer registry data from the Surveillance, Epidemiology, and End Results program (SEER 9), we examined sex-specific 5-year relative survival trends for children (0-14 years old), AYAs (15-39 years old), and older adults (40 years and older) diagnosed with cancer during 1973-2009 and followed through the end of 2014. The analysis was conducted with and without Kaposi sarcoma (KS) and lymphomas, and by two time periods: 1973-1977 (before the human immunodeficiency virus/acquired immunodeficiency syndrome [HIV/AIDS] epidemic) and 2005-2009 (after the HIV/AIDS epidemic waned). RESULTS: A total of 3 209 721 invasive cancer cases were included in the study (27 646 children, 213 930 AYAs, and 2 968 145 older adults; 24 803 children, 178 741 AYAs, and 2 844 062 older adults when KS and lymphoma cases were excluded). We found that 5-year relative survival for AYAs exceeded that of children and older adults before the onset of the HIV/AIDS epidemic (eg, during 1973-1979, 0.58-0.67 among male AYAs as compared with 0.47-0.61 for male children and 0.36-0.42 for male older adults; among female AYAs, the numbers were 0.73-0.77 as compared with 0.51-0.65 for female children and 0.52-0.55 for female older adults); substantially declined during 1983-1997 when HIV/AIDS lacked effective treatment among male AYAs; and returned to be higher than most age groups by the late 1990s after HIV/AIDS was controlled. Nonetheless, comparison of survival improvement between 1973-1977 and 2005-2009 demonstrated less progress in AYAs than other age groups, which was due to AYAs' better baseline survival and larger survival gains among children and older adults in recent years. CONCLUSIONS: Apart from the temporary impact of HIV/AIDS, survival among AYA cancer patients has shown sustained improvement and superiority relative to other age groups. However, these encouraging findings do not negate the distinctive challenges in cancer diagnosis, treatment, and survivorship faced by AYAs.

Kaposiform hemangioendothelioma without cutaneous involvement.

PURPOSE: We sought to characterize the clinical features and management of patients diagnosed as Kaposiform hemangioendothelioma (KHE) without cutaneous involvement. METHODS: The electronic patient chats at six Triple A hospitals in China were searched to find all patient diagnoses with KHE without cutaneous involvement. RESULTS: Of 30 patients (mean age at diagnosis, 55.6 months), 17 (56.7%) were male. Fourteen (46.7%) patients were associated with Kasabach-Merritt phenomenon (KMP). Patients with KMP were significantly more likely to have lesions involving truck compared to patients without KMP (odds ratio 10.000; 95% confidence interval 1.641-60.921; P = 0.011). Other common complication included severe anemia and decreased range of motion. In the majority of cases (93.3%), the lesions were highly infiltrative and locally invasive with ill-defined margins. Histological examination was required in all patients without KMP for precise diagnosis. In all, 16 (53.3%) patients received corticosteroid treatment, 19 (63.3%) received oral sirolimus treatment, 7 (23.3%) received intravenous vincristine, and 5 (16.7%) patients used propranolol. Patients had varied responses to conventional drugs, whereas all patients receiving sirolimus treatment had better response. In all, three patients (10%) died of disease, all presented with KMP. Feature of these recalcitrant cases (death) included young age, visceral location, extensive involvement, and lack of improvement with high-dose corticosteroids. CONCLUSIONS: Our study clearly demonstrated that KHE without cutaneous involvement could be associated with important complication, which might result in death or severe morbidity. Increased awareness of KHE without cutaneous involvement is required for early diagnosis and aggressive therapy in an attempt to prevent complication.

Survival from childhood cancers in Eastern Africa: A population-based registry study.

Cancers occurring in children in Africa are often underdiagnosed, or at best diagnosed late. As a result, survival is poor, even for cancers considered 'curable'. With limited population-level data, understanding the actual burden and survival from childhood cancers in Africa is difficult. In this study, we aimed at providing survival estimates for the most common types of cancers affecting children aged 0-14 years, in three population-based Eastern African registries; Harare, Zimbabwe (Kaposi sarcoma, Wilms tumour (WT), non-Hodgkin lymphoma (NHL), retinoblastoma, and acute lymphocytic leukaemia (ALL)), Kampala, Uganda (Burkitt lymphoma, Kaposi sarcoma, WT, and retinoblastoma), and Nairobi, Kenya (ALL, retinoblastoma, WT, Burkitt lymphoma, and Hodgkin lymphoma). We included cases diagnosed within the years 1998-2009 and followed up till the end of 2011. We estimated the observed and relative survival at 1, 3, and 5 years after diagnosis. We studied 627 individual patient records. Median follow-up ranged from 2.2 months for children with Kaposi sarcoma in Harare to 30.2 months for children with ALL in Nairobi. The proportion of children lost to follow-up was highest in the first year after diagnosis. In Harare and Kampala, the 5-year relative survival was <46% for all cancer types. The 5-year relative survival was best for children in Nairobi, though with wider confidence intervals. Survival from childhood cancers in Africa is still poor, even for cancers with good prognosis and potential for cure. Supporting cancer detection, treatment, and registration activities could help improve survival chances for children with cancers in Africa.

[Profile of Kaposi sarcoma patients in the competence network HIV/AIDS]. / Profil der Kaposi-Sarkom-Patienten im Kompetenznetz HIV/AIDS.

BACKGROUND: Kaposi's sarcoma (KS) represents the most common AIDS-defining neoplasm. Only very few studies regarding the course and treatment of human immunodeficiency virus (HIV)-associated KS have been carried out in Germany. OBJECTIVE: In this study the course of HIV-associated KS was observed in patients from the cohort database of the competence network for HIV/AIDS. MATERIAL AND METHODS: Data from HIV-associated KS patients from 9 German core centers from 1987 to 2011 were retrospectively collected. Kaplan-Meier curves for the recurrence and survival probability were calculated. RESULTS: In 222 patients KS was diagnosed at a median age of 38.5 ± 10.1 years. Men were almost exclusively affected (97.7%). The HIV viral load at the time of diagnosis was in 7.4% <50 copies/ml. Of the patients 55.5% developed KS with a CD4 cell count of <200 cells/µl and 9.5% with >500 cells/µl. In 68 patients KS therapy consisted exclusively of the optimization or initiation of antiretroviral therapy (ART). In addition, 71 patients were treated with pegylated liposomal doxorubicin. During the median follow-up period of 8.9 ± 4.9 years, 80.2% of the patients were free of KS recurrence. Survival rates after 5 and 10 years were 96.8% and 91.3%, respectively. CONCLUSION: Even with a good immune status HIV-associated KS occurred. An effective ART was the most important mainstay of therapy. With appropriate therapy, HIV-positive patients with KS showed a good survival rate.

Triple therapy of vincristine, bleomycin and etoposide for children with Kaposi sarcoma: Results of a study in Malawian children.

BACKGROUND: Kaposi sarcoma (KS) is the most common paediatric cancer in human immunodeficiency virus (HIV) endemic countries of sub-Saharan Africa, but there is little research on management and outcomes. METHODS: Children with KS at Queen Elizabeth Central Hospital, Blantyre, Malawi treated between August 2012 and March 2015 with six courses of vincristine, bleomycin and etoposide combination chemotherapy, including antiretroviral therapy (ART) if HIV infected, were studied and outcomes compared with previously reported results. FINDINGS: Fifty-six children were included; 38 (68%) were male; and 48 (86%) were HIV positive, of whom 36 (77%) were on ART at diagnosis. Median age at diagnosis was 8 years (interquartile range [IQR] 3-12) and median follow-up was 16.9 months (IQR 3.4-36.4). Quality of life improved in 45 (80%) children; the median Lansky Score increased from 80% pre-treatment to 100% post-treatment. Eighteen (32%) children had complete response to treatment. At 12 months, overall survival was 71% (95% confidence interval [CI] 56-82) and event-free survival (event = death, loss to follow-up or relapse) was 50% (95% CI 36-63). At 1 year, the risk of loss to follow-up was 13.4%. In a previous, same-site, randomized controlled study of vincristine monotherapy, vincristine and bleomycin, or oral etoposide, oral etoposide monotherapy had the best outcome with survival at 12 month of 66% (95% CI 46-80) and event-free survival of 52% (95% CI 33-68); however, loss to follow-up was not reported. CONCLUSION: Overall survival, event-free survival and quality of life appear to have improved with this three-agent combination chemotherapy; however larger, randomized studies are needed to determine optimal management.

Kaposi's sarcoma: Good outcome with doxorubicin, bleomycin and vincristine sulphate (ABV) chemotherapy and highly active antiretroviral therapy.

There is little published information on effective treatment of Kaposi's sarcoma (KS) in children in low-income countries. We prospectively treated 12 patients with an institutional review board-approved protocol consisting of four monthly courses of doxorubicin (Adriamycin), bleomycin and vincristine sulphate (ABV), with highly active antiretroviral therapy (HAART) plus co-trimoxazole prophylaxis for those who were HIV-positive, with additional vincristine if remission was not achieved after 4 months. Maintenance HAART plus co-trimoxazole was given to all HIV-positive patients. A fine-needle aspirate and CD4+ count were done if possible, and staging was performed according to Mitsuyasu. Eight of ten HIV-positive patients with stage III - IVB disease, and both HIV-negative patients with stage I disease, were in remission after 473 - 1 490 (mean 939) days. One patient died after absconding during treatment, and one died from neutropenia-related pulmonary infection. ABV with or without HAART is an effective treatment option for children with KS.

Differences in survival among adults with HIV-associated Kaposi's sarcoma during routine HIV treatment initiation in Zomba district, Malawi: a retrospective cohort analysis.

Background: The HIV epidemic is a major public health concern throughout Africa. Malawi is one of the worst affected countries in sub-Saharan Africa with a 2014 national HIV prevalence currently estimated at 10% (9.3-10.8%) by UNAIDS. Study reports, largely in the African setting comparing outcomes in HIV patients with and without Kaposi's sarcoma (KS) indicate poor prognosis and poor health outcomes amongst HIV+KS patients. Understanding the mortality risk in this patient group could help improve patient management and care. Methods: Using data for the 559 adult HIV+KS patients who started ART between 2004 and September 2011 at Zomba clinic in Malawi, we estimated relative hazard ratios for all-cause mortality by controlling for age, sex, TB status, occupation, date of starting treatment and distance to the HIV+KS clinic. Results: Patients with tuberculosis (95% CI: 1.05-4.65) and patients who started ART before 2008 (95% CI: 0.34-0.81) were at significantly greater risk of dying. A random-effects Cox model with Log-Gaussian frailties adequately described the variation in the hazard for mortality. Conclusion: The year of starting ART and TB status significantly affected survival among HIV+KS patients. A sub-population analysis of this kind can inform an efficient triage system for managing vulnerable patients.

Updating vital status by tracking in the community among patients with epidemic Kaposi sarcoma who are lost to follow-up in sub-Saharan Africa.

BACKGROUND: Throughout most of sub-Saharan Africa (and, indeed, most resource-limited areas), lack of death registries prohibits linkage of cancer diagnoses and precludes the most expeditious approach to determining cancer survival. Instead, estimation of cancer survival often uses clinical records, which have some mortality data but are replete with patients who are lost to follow-up (LTFU), some of which may be caused by undocumented death. The end result is that accurate estimation of cancer survival is rarely performed. A prominent example of a common cancer in Africa for which survival data are needed but for which frequent LTFU has precluded accurate estimation is Kaposi sarcoma (KS). METHODS: Using electronic records, we identified all newly diagnosed KS among HIV-infected adults at 33 primary care clinics in Kenya, Uganda, Nigeria, and Malawi from 2009 to 2012. We determined those patients who were apparently LTFU, defined as absent from clinic for ≥90 days at database closure and unknown to be dead or transferred. Using standardized protocols which included manual chart review, telephone calls, and physical tracking in the community, we attempted to update vital status amongst patients who were LTFU. RESULTS: We identified 1222 patients with KS, of whom 440 were LTFU according to electronic records. Manual chart review revealed that 18 (4.1%) were classified as LFTU due to clerical error, leaving 422 as truly LTFU. Of these 422, we updated vital status in 78%; manual chart review was responsible for updating in 5.7%, telephone calls in 26%, and physical tracking in 46%. Among 378 patients who consented at clinic enrollment to be tracked if they became LTFU and who had sufficient geographic contact/locator information, we updated vital status in 88%. Duration of LTFU was not associated with success of tracking, but tracking success was better in Kenya than the other sites. CONCLUSION: It is feasible to update vital status in a large fraction of patients with HIV-associated KS in sub-Saharan Africa who have become LTFU from clinical care. This finding likely applies to other cancers as well. Updating vital status amongst lost patients paves the way towards accurate determination of cancer survival.

Trends in Malignancies among Korean Patients Infected with Human Immunodeficiency Virus in the Highly Active Antiretroviral Therapy Era.

Since the introduction of highly active antiretroviral therapy, the life span of people with human immunodeficiency virus (HIV) or AIDS (PWHA) has been extended significantly. Therefore, the importance of non-AIDS-defining cancers (NADCs), as well as AIDS-defining cancers (ADCs) has increased. There is little information concerning the epidemiology of malignancies in PWHA in Korea. A descriptive epidemiologic study was conducted at a tertiary care hospital in Korea. PWHA who visited Pusan National University Hospital from January 2000 to October 2014 were included. Demographics and clinical data were obtained from the medical records and analyzed. A total of 950 PWHA were observed for 4,439.71 person-years. Forty-eight episodes (5.05%) of cancers were diagnosed in 47 patients. Mean age of the enrolled patients was 40.66 ± 12.15 years and 88% were male. Among the 48 cancer episodes, 20 (42%) were ADCs and 28 were NADCs. The most common ADCs was non-Hodgkin's lymphoma (53.6%), followed by Kaposi's sarcoma (17.9%). The most common NADCs were lung cancer (25%) and hepatocellular carcinoma (25%). The overall incidence of total cancers, ADCs, and NADCs was 10.8 (95% confidence interval [CI], 8.0-14.3), 4.5 (95% CI, 2.8-7.0), and 6.3 (95% CI, 4.2-9.1)/1,000 person-years, respectively. NADCs accounted for 12/15 (80%) of cancers among PWHA with good adherence to care. The 5-year survival rate of PWHA and NADC was 26.3%. NADCs have become the main type of malignancy among Korean PWHA with good adherence to care. Effective strategies to improve screening of NADCs among PWHA are required in Korea.

Outcome of second kidney transplantation in patients with previous post-transplantation Kaposi's sarcoma: A French retrospective study.

This retrospective study concerned 8 patients with post-transplantation Kaposi's sarcoma (pt-KS) after a first kidney transplant who later had a second kidney transplantation. Pt-KS was widespread, with lymph node or visceral involvement in 7 cases. Complete remission was observed in 6 cases and partial remission in 2. After the second kidney transplantation, only 2 cases showed recurrence of skin KS, one with previous complete remission of KS and one with partial remission. The mean delay between stability or complete remission of KS and retransplantation was 2.0 and 7.3 years in patients with and without relapse, respectively. Both recurrent cases showed complete KS remission after tapering immunosuppression therapy and/or switching a calcineurin inhibitor to a mammalian target of rapamycin inhibitor. We compared these 8 cases to 24 controls who had undergone 2 kidney transplantations but did not have KS, matching on sex, age and phototype. Cases and controls did not differ in graft function or survival. A second kidney transplantation may be possible after pt-KS and has acceptable risk, especially after a long complete remission of pt-KS.

Disparities in Kaposi sarcoma incidence and survival in the United States: 2000-2013.

OBJECTIVE: Geographic and racial disparities may contribute to variation in the incidence and outcomes of HIV-associated cancers in the United States. METHOD: Using the Surveillance, Epidemiology, and End Results (SEER) database, we analyzed Kaposi sarcoma (KS) incidence and survival by race and geographic region during the combined antiretroviral therapy era. Reported cases of KS in men from 2000 to 2013 were obtained from 17 SEER cancer registries. Overall and age-standardized KS incidence rates were calculated and stratified by race and geographic region. We evaluated incidence trends using joinpoint analyses and calculated adjusted hazard ratios (aHR) for overall and KS-specific mortality using multivariable Cox proportional hazards models. RESULTS: Of 4,455 KS cases identified in men younger than 55 years (median age 40 years), the annual percent change (APC) for KS incidence significantly decreased for white men between 2001 and 2013 (APC -4.52, p = 0.02). The APC for AA men demonstrated a non-significant decrease from 2000-2013 (APC -1.84, p = 0.09). Among AA men in the South, however, APC has significantly increased between 2000 and 2013 (+3.0, p = 0.03). In addition, compared with white men diagnosed with KS during the same time period, AA men were also more likely to die from all causes and KS cancer-specific causes (aHR 1.52, 95% CI 1.34-1.72, aHR 1.49, 95% CI 1.30-1.72 respectively). CONCLUSION: Although overall KS incidence has decreased in the U.S., geographic and racial disparities in KS incidence and survival exist.

Clinical and laboratory characteristics, staging, and outcomes of individuals with AIDS-associated Kaposi's sarcoma at an university hospital.

BACKGROUND:: Kaposi's sarcoma continues to be the most common human immunodeficiency virus - associated neoplasm with considerable morbidity and mortality. OBJECTIVE:: To describe the clinical and laboratory characteristics, initial staging, and outcomes of aids patients with Kaposi's sarcoma at an university hospital of Recife, Pernambuco. METHODS:: This is a descriptive study with analytic character, retrospective, of a case series between 2004 and 2014. RESULTS:: Of the 22 patients included in the study, 20 were aged <40 years (72.7%). The majority had CD4+ T lymphocyte counts of <200 cells/mm3 (77.3%) and human immunodeficiency virus loads of <100,000 copies/mL (78.9%). Lesions were most commonly observed on the skin (90%), and internal organs were affected in 11 of the 22 patients. Only 7 (31.8%) of the 22 patients were undergoing antiretroviral therapy (ART) at the time of Kaposis sarcoma diagnosis, and the initial disease staging classification was high risk (Aids Clinical Trials Group Oncology Committee) in 19 of the 22 patients (86.4%). Regarding Kaposi's sarcoma treatment, 17 of 22 patients (77.3%) underwent systemic chemotherapy + ART and 5 were treated exclusively with ART. Eight of the 22 patients died (36.5%); of these, 87.5% had died within one year of Kaposi's sarcoma diagnosis. LIMITATION OF THE STUDY:: Without a control group, this study cannot be used to generate hypotheses. CONCLUSIONS:: Despite the association between aids and late Kaposi's sarcoma diagnosis in the study population, including an unfavorable risk at the time of staging, a lower mortality rate was observed relative to other studies; this might be related to access to a specialized health service.

Clinical and laboratory characteristics, staging, and outcomes of individuals with AIDS-associated Kaposi's sarcoma at an university hospital

Abstract: Background: Kaposi's sarcoma continues to be the most common human immunodeficiency virus - associated neoplasm with considerable morbidity and mortality. Objective: To describe the clinical and laboratory characteristics, initial staging, and outcomes of aids patients with Kaposi's sarcoma at an university hospital of Recife, Pernambuco. Methods: This is a descriptive study with analytic character, retrospective, of a case series between 2004 and 2014. Results: Of the 22 patients included in the study, 20 were aged <40 years (72.7%). The majority had CD4+ T lymphocyte counts of <200 cells/mm3 (77.3%) and human immunodeficiency virus loads of <100,000 copies/mL (78.9%). Lesions were most commonly observed on the skin (90%), and internal organs were affected in 11 of the 22 patients. Only 7 (31.8%) of the 22 patients were undergoing antiretroviral therapy (ART) at the time of Kaposis sarcoma diagnosis, and the initial disease staging classification was high risk (Aids Clinical Trials Group Oncology Committee) in 19 of the 22 patients (86.4%).

Eight of the 22 patients died (36.5%); of these, 87.5% had died within one year of Kaposi's sarcoma diagnosis. Limitation of the study: Without a control group, this study cannot be used to generate hypotheses.

Severe Kaposi Sarcoma in an Urban Public Hospital.

The national incidence of epidemic Kaposi sarcoma (KS) has decreased dramatically since the availability of combined antiretroviral therapy. Despite national trends, we continue to see admissions for KS. Electronic medical records were queried to identify patients with HIV who were admitted with active KS between 2010 and 2013 and records were reviewed to determine patient characteristics and factors affecting survival. Data were collected from all hospital admissions until death or May 1, 2015. Kaplan-Meier survival analysis with log-rank tests were used to test for differences in survival and Cox proportional hazards models were used to assess the prognostic value of variables. Odds ratios were calculated to determine factors associated with death during hospital admissions. Forty-three patients were admitted 141 times, with 81 admissions specifically related to KS. The majority of patients were highly immunosuppressed when KS was diagnosed (median CD4 count: 11), and 68% had multiple organ involvement with KS. Comorbidities at diagnosis included hepatitis B (26%) and pneumocystis pneumonia (33%). Frequent reasons for admission included skin and soft tissue complaints (28.4%) and respiratory complaints (27.2%). The estimated median survival after KS diagnosis was 3.0 years. Lung involvement, liver involvement, poor performance status, and low CD4 T cell count (<50) were associated with lower survival. Lung infections were the only admission diagnoses significantly associated with an increased odds of death during admission (OR: 5.42, 95% CI: 1.04-28.24). KS in our population is associated with poor access to healthcare and management of HIV. Factors affecting survival, including CD4 count and pulmonary involvement of KS, are in accordance with previous studies. Pulmonary KS should therefore be considered early in AIDS patients presenting with respiratory complaints. Our study also demonstrated that respiratory infections are associated with significant morbidity in patients with KS.
