ABSTRACT

Wilms tumor (WT) is the most common renal malignancy of childhood. The common metastatic sites are the lungs, liver, and lymph nodes, with brain and bone metastases occurring rarely. Metastatic disease can be present at initial diagnosis or may occur with relapse or disease progression. The majority of relapses in WT occur within the first two years post-treatment. Late relapses are rare. This article describes four cases of WT, each demonstrating an unusual site or timing of metastases. Case 1 presented primarily with jaw metastases, Case 2 presented with bone (vertebrae) and spinal metastases manifesting as paraplegia, at relapse one year after completion of treatment, Case 3 presented with isolated liver metastases four years after treatment completion, and Case 4 presented with brain metastases after six weeks of treatment abandonment. This case series demonstrates the varied pattern of metastases of WT and highlights the need for a high index of suspicion for WT among patients who present with unusual sites of tumor or for metastasis in those who present with neurologic symptoms during or after treatment.

ABSTRACT

PURPOSE: To build capacity for improved treatment of locally advanced cervical cancer in Ghana, including computed tomography (CT) staging and intensity modulated radiotherapy (IMRT). MATERIALS AND METHODS: Patients with histologically confirmed cervical cancer were prospectively staged with abdominopelvic CT and ultrasound and offered the opportunity to have IMRT instead of conventional two-dimensional radiotherapy. The development of an efficient, high-quality, and safe IMRT program was facilitated by investment in new technology and comprehensive training of the interdisciplinary radiotherapy team in collaboration with a North American center of excellence. RESULTS: Of 215 patients with cervical cancer referred in 2022, 66% were able to afford CT scans and 26% were able to afford IMRT. Lymph node metastases were identified in 52% of patients by CT but in only 2% of patients by ultrasound. The use of CT resulted in 63% of patients being upstaged and changed treatment intent or radiation treatment volumes in 67% of patients. Patients who had IMRT experienced fewer acute side effects and were more likely to complete treatment as planned. CONCLUSION: It is feasible to provide state-of the-art cancer treatment with CT staging and IMRT to patients with cervical cancer in low-resource settings and achieve meaningful improvements in outcomes. It requires a broad commitment by program leadership to invest in technology and staff training. Major challenges include balancing improved clinical care with reduced patient throughput when radiation treatment capacity is constrained, and with the additional cost in the absence of universal health coverage.

ABSTRACT

PURPOSE: To document progress and bottlenecks in breast cancer management in sub-Saharan Africa, subsequent to a 2013 pilot survey conducted through the African Organization for Research and Treatment in Cancer (AORTIC) network. METHODS: An anonymous survey of breast cancer management was conducted in 2018 among AORTIC members. Results concerning respondent specialty, access to tumor boards, treatment accessibility, diagnostic services, and factors influencing treatment outcomes were compared with the 2013 findings. RESULTS: Thirty-seven respondents from 30 facilities in 21 sub-Saharan Africa countries responded. The majority (92%) were clinical oncologists. Radiotherapy facilities were available in 70% of facilities. Seventy-eight percent of these had linear accelerators, and 42% had cobalt60 machines. Eighty percent of facilities had multidisciplinary tumor boards. Immunohistochemistry was routinely performed in 74% of facilities, computed tomography scan in 90%, bone scan in 16%, and positron emission tomography scans in 5%. Anthracyclines, taxanes, tamoxifen, letrozole, anastrozole, and zoledronic acid were available in the majority; trastuzumab, fertility, and genetic counseling were available in 66%, 58%, and 16%, respectively. There were a 50% increase in oncologist respondents over 2013 and a > 50% increase in radiotherapy facilities, particularly linear accelerators. Availability of trastuzumab, aromatase inhibitors, and taxanes increased. Immunohistochemistry capacity remained the same, whereas facilities harvesting at least 10 axillary lymph nodes increased. Bone scan facilities decreased. Responses suggested improved diagnostic services, systemic therapies, and radiotherapy. Sociocultural and economic barriers, system delays, and advanced stage at presentation remain. CONCLUSION: Clinicians in sub-Saharan Africa have basic tools to improve breast cancer outcomes, recording positive strides in domains such as radiotherapy and systemic therapy. Socioeconomic and cultural barriers and system delays persist. Workforce expansion must be prioritized to improve quality of care to improve outcomes.

ABSTRACT

PURPOSE: It is established that addition of systemic therapy to locoregional treatment for breast cancer improves survival. However, reliable data are lacking about the outcomes of such treatment in women with breast cancer in low middle-income countries. We compared the outcomes of treatment in patients who had received neoadjuvant chemotherapy (NACT) or adjuvant chemotherapy and examined the factors associated with breast cancer recurrence and survival at the National Radiotherapy Oncology and Nuclear Medicine Centre, Korle Bu Teaching Hospital, Ghana. METHODS: This was a retrospective cohort study. The medical charts of women with breast cancer managed at the National Radiotherapy Oncology and Nuclear Medicine Centre from 2005 to 2014 were reviewed. A total of 388 patients with a median follow-up of 48 months were included in the study. Logistic regression was used to estimate the risk of recurrence. Survival was estimated using cox proportional hazards model. All models were adjusted with clinicopathologic variables. A P value of < .05 was considered statistically significant. RESULTS: Fifty-nine percent received adjuvant chemotherapy. In an adjusted logistic model, no difference was observed in locoregional recurrence between patients receiving NACT compared with those receiving adjuvant chemotherapy (odds ratio = 1.05; 95% CI, 0.44 to 2.47). However, NACT recipients had a higher likelihood of distant recurrence (odds ratio = 1.97; 95% CI, 1.24 to 3.15). In a multivariable analysis, no differences were observed in overall survival between the two chemotherapy groups (hazard ratio = 1.43; 95% CI, 0.91 to 2.26). CONCLUSION: NACT yields similar outcomes compared with adjuvant chemotherapy; however, recipients of NACT with advanced disease may have more distant failures. Early detection in a resource-limited setting is therefore crucial to optimal outcomes, significantly limiting recurrence and improving survival.
