    The clinicopathological profile and value of multidisciplinary management of pediatric brain tumors in a low-income setting
    (Taylor & Francis, 2022-10-31) Nyeko, Richard; Kambugu, Joyce Balagadde; Angom, Racheal; Senyonjo, Hussein; Kibudde, Solomon; Geriga, Fadhil; van Heerden, Jaques
    ABSTRACT Brain tumors are the most common solid tumors in children and a leading cause of cancer-related mortality in children worldwide. Data on the epidemiology and management of pediatric brain tumors in Uganda are limited. We aimed to assess the clinicopathological profile and management of pediatric brain tumors at the national oncology center in Uganda since the inception of weekly multidisciplinary meetings. Records of children younger than19 years diagnosed with primary brain tumors at Uganda Cancer Institute between 2017 and 2021 were retrospectively reviewed. Patient and tumor characteristics were collected with multidisciplinary team management treatment plans for analysis. There were 35 patients evaluated, most of whom were males (57.1%). Craniopharyngioma (n = 9, 25.7%) was the most common brain tumor, followed by astrocytoma (n = 5, 14.2%) and medulloblastoma (n = 4, 11.4%). Management included surgical resection in 28.5% of patients, chemotherapy (28.6%), radiotherapy (17.1%) and palliative care (20.0%). Over the last five years, there were increasing trends in the number of cases discussed in the multidisciplinary team and the number for whom the multidisciplinary management decisions were implemented. The majority (n = 18, 51.4%) of the children with brain tumors were alive and active in care, 34.2% abandoned treatment/lost to follow-up, and 8.6% died. The relative distribution of pediatric brain tumors types in Uganda Cancer Institute differs slightly from international reports, and there has been a notable increase in the number of cases over the years. Implementing multidisciplinary management decisions benefited patients and decreased abandonment and patient loss to follow-up.

    The management of osteosarcoma in children and adolescents in a resource-limited setting: quality improvement considerations to improve treatment outcomes
    (BMC Cancer, 2024) Nyeko, Richard; Geriga, Fadhil; Angom, Racheal; Kambugu, Joyce Balagadde; Heerden, Jaques van
    Background The survival rates for children and adolescents with osteosarcoma in low-income countries are poor. Insufficient data regarding the challenges of managing osteosarcoma in resource-limited settings has been published. We evaluated the treatment of osteosarcoma in children and adolescents with the aim of improving the health system and management outcomes. Methods We sourced data on children under 18 years treated for osteosarcoma at the Uganda Cancer Institute between January 2016 and December 2020. Descriptive statistics and Kaplan-Meier survival analysis were used. Results Seventy-four osteosarcoma cases were identified, with a median age of 13 years (IQR 9.8–15). Referrals were made after a median of 28 days (range 1-147). Before appropriate referral, more than a quarter (26%) had undergone invasive procedures that could compromise tumour integrity and outcome. Half (50%) of the patients had metastatic disease at diagnosis, primarily to the lungs (n=43; 92%). Only 14 (33%) patients received neoadjuvant chemotherapy. Forty-three (58.1%) patients underwent limb amputation surgery, including 25 localized tumours and 18 patients with distant metastatic disease. No metastatectomies were performed. Adjuvant chemotherapy was delayed for longer than 21 days in 26 (61%) patients. No pathology reports described the status of resection margins or the degree of chemotherapy-induced necrosis. Twenty-six (35%) patients abandoned treatment, mainly due to pending radical surgery (n=18/26; 69%). Only 18% (n=13) were still alive; 46% (n=34) had died; and 37% (n=27) had an unknown status. The median overall survival was 1.1 years, and was significantly negatively affected by disease metastasis, timing of adjuvant therapy, and treatment abandonment. Conclusions Osteosarcoma outcomes for children and adolescents at the Uganda Cancer Institute are extremely poor. The quality of care can be improved by addressing delayed referrals, high rates of prior manipulative therapy, metastatic disease, treatment abandonment, surgical challenges, and delayed resumption of adjuvant chemotherapy.

    Oral–visceral iatrogenic Kaposi sarcoma following treatment for acute lymphoblastic leukemia: a case report and review of the literature
    (Journal of Medical Case Reports, 2022) Nyeko, Richard; Geriga, Fadhil; Angom, Racheal; Kambugu, Joyce Balagadde
    Background: There have hardly been any reported cases of children presenting with Kaposi sarcoma as a second malignancy following treatment for acute lymphoblastic leukemia outside a transplant setting. Case presentation: We report a case of a 5-year-old boy of Bantu origin, which, to our knowledge, could be only the second reported case of oral–visceral Kaposi sarcoma after acute lymphoblastic leukemia treatment. The patient presented with a 1-month history of progressive, non-painful, soft tissue oral mass, 1 month after completing treatment for high-risk acute lymphoblastic leukemia. He was successfully treated for Kaposi sarcoma on a two-drug regimen (bleomycin and vincristine) with good clinical response. Conclusion: Visceral Kaposi sarcoma as a second malignancy may occur after pediatric acute lymphoblastic leukemia treatment, but its rarity makes it unlikely to raise suspicion among clinicians, thus precluding early diagnosis and treatment. We recommend routine evaluation for Kaposi sarcoma lesions in children undergoing long-term surveillance following treatment for childhood acute leukemia

    Reproductive Concerns and Associated Factors Among Adolescent and Young Adult Cancer Survivors in Uganda: A Hospital-Based Cross-Sectional Study
    (Journal of Adolescent and Young Adult Oncology., 2024) Nyeko, Richard; Okello, Nelson; Abeja, Christine Joy; Adyanga, Proscovia; Apio, Betty; Nabasirye, Caroline Kambugu; Mwa, Pamella Aol; Angom, Racheal; Geriga, Fadhil; Buser, Julie
    Purpose: Reproductive health (RH) is a critical issue among cancer survivors worldwide. However, in developing countries where RH services for patients with cancer are often lacking, reproductive concerns among adolescent and young adult (AYA) survivors remain uncertain. In this study, we assessed the reproductive concerns of AYA cancer survivors in a resource-limited context of Uganda. Methods: We collected data from AYA cancer survivors at two facilities in Uganda using an intervieweradministered questionnaire. Descriptive statistics were calculated, one-way analysis of variance was used for intergroup comparisons, and multiple regressions were used to test for predictors of reproductive concerns. Results: A total of 110 AYA cancer survivors, with a median age of 20 years (interquartile range [IQR], 18–22), were interviewed. More than half (53.6%) of the respondents were males. The median time since cancer diagnosis was 19 months (IQR, 13.0–35.0). Almost all (91.8%) respondents had a future desire to have children, but only 15.5% received reproductive counseling. The mean total score for the reproductive concern subscales was highest for the fertility concern, followed by the information-seeking and health-related concerns. Reproductive counseling, desire to have children, and respondents’ age were the factors influencing reproductive concern. Conclusions: The study shows a strong desire for biological parenthood with very low reproductive counseling among AYA cancer survivors, who remain concerned about their fertility, information needs, and health. This outcome underscores the need to integrate RH services into resource-limited cancer care settings. Keywords: reproductive health, concerns, adolescents and young adults, cancer survivors
