The challenges of managing breast cancer in the developing world- a perspective from sub- Saharan Africa

PKCommunicable diseases are the major cause of mortality in lower-income countries. Consequently, local and international resources are channelled mainly into addressing the impact of these conditions. HIV, however, is being successfully treated, people are living longer, and disease patterns are changing. As populations age, the incidence of cancer inevitably increases. The World Health Organization has predicted a dramatic increase in global cancer cases during the next 15 years, the majority of which will occur in low- and middle-income countries. Cancer treatment is expensive and complex and in the developing world 5% of global cancer funds are spent on 70% of cancer cases. This paper reviews the challenges of managing breast cancer in the developing world, using sub-Saharan Africa as a model

How long are elderly patients followed up with mammography after the diagnosis of breast cancer? A single-centre experience in a developing country

Background. The effect of breast cancer on elderly South African (SA) patients is not well characterised. The lack of data with regard to disease burden, post-treatment surveillance and breast cancer relapse poses a challenge to providing optimum follow-up care to this group of patients.Objectives. To assess the effect of breast cancer and adherence to post-treatment surveillance programmes among the local elderly population attending the breast oncology clinics at Addington and Inkosi Albert Luthuli Central hospitals in Durban, KwaZulu-Natal, SA.Methods. A retrospective review was undertaken of all patients aged ≥65 years diagnosed with breast cancer during 2007. Hospital records were reviewed for a period of 5 years to ascertain the stage of the disease, treatment received,  adherence to post-treatment surveillance mammograms, incidence of new mammographic findings and recurrence, site of recurrence, mode of detection of recurrence, disease-free survival, and overall survival rates at 5 years.Results. In our study, the incidence of breast cancer in the elderly population was 26.7%. A significant percentage of patients (56.3%) were diagnosed at an advanced stage of disease. Of the 46.9% who had received surveillance  mammography, only 6.3% received their post-treatment surveillance mammograms on time, in accordance with international recommendations. New mammographic findings were detected in 26.7% of patients during the 5-year follow-up. During the follow-up period, 15.6% of the total number of study patients presented with disease recurrence. Eighty percent of cases of recurrence were detected clinically. The overall survival at 5 years was 65.6%.Conclusion. Our study highlights the significant number of elderly patients with advanced disease at diagnosis, poor compliance with internationally recommended annual post-treatment surveillance mammograms, and the relatively low overall 5-year survival rate compared with that of international studies

Prevalence of breast tuberculosis: Retrospective analysis of 65 patients attending a tertiary hospital in Durban, South Africa

Background. Breast tuberculosis (BTB) is uncommon, but not rare. Knowledge of the ways in which it can present can prevent unnecessary invasive procedures and delay in diagnosis.Objectives. To describe the clinical and radiological findings in patients with BTB, including evaluation of current treatment methods.Methods. We retrospectively analysed 65 patients diagnosed with BTB at Addington and King Edward VIII hospitals, Durban, South Africa, between 2000 and 2013. Demographic, clinical and radiological findings and treatment outcomes were noted.Results. A total of 11 092 patients underwent breast investigations between 2009 and 2013, with a prevalence of BTB for the period of 0.3% (30 patients). Of the 65 patients diagnosed between 2000 and 2013, 64 were female (98.5%) and one was male (1.5%). The age range was 23 - 69 years (mean 38.5). The most common mammographic pattern was density (39.4%) and the least common a mass (6.1%). Isolated axillary lymphadenitis was found in 12.1%. Abscess was the commonest ultrasound pattern (39.0%). Of the 47 patients with a known history of pulmonary tuberculosis (TB), 68.1% (n=32) did not have radiological evidence of previous or concurrent pulmonary TB, nor was there evidence of TB elsewhere. Of 47 patients with known HIV status, 34 were HIV-positive. Fine-needle aspiration cytology had sensitivity of only 28% compared with 94% for histology. Of those treated, 72.7% obtained full resolution following 9 months of TB treatment; 25.0% did not complete treatment, and 2.3% (n=1) died while on treatment. Follow-up data on relapse rates after treatment completion and disease resolution are scanty.Conclusion. Understanding and being aware of the various presentations of BTB make it possible to treat most patients successfully.

An initial benchmark of the quality of the diagnosis and surgical treatment of breast cancer in South Africa

Background. Monitoring quality indicators to improve breast cancer care is well established in high-income countries. This is the first evaluation of diagnostic and surgical quality indicators for initial benchmarking of breast cancer care in South Africa (SA). Objective. To measure the adherence rates to quality indicators among women with breast cancer in SA. Methods. Ten quality indicators were evaluated for 3 545 breast cancer patients across four SA surgical breast units using a shared electronic patient record system. Data quality and adherence rates with differences between units were determined. The effect of HIV status on adherence was assessed by multivariate Poisson regression analyses. Results. Our electronic patient record reliably measured most quality indicators. Rates of positive margins (5.7%), overall axillary surgery (95.8%) and appropriate treatment sequencing in locally advanced breast cancer patients (98.4%) consistently reached minimum international standards. Rates of multidisciplinary team discussion (72.2%), radiotherapy (66.7%) and sentinel node biopsy (39.6%) showed wide cross-site variance. Histopathology reporting (62.0%), breast-conserving surgery (19.4%) and number of nodes excised with axillary dissection (47.3%) and sentinel node biopsy (82.7%) were consistently below minimum standards. Unit volumes were achieved consistently in Gauteng Province, but only for some years in KwaZulu-Natal Province; surgeon volumes were achieved across all units. HIV status did not affect adherence levels. Most quality indicators were well measurable, but data quality on reoperations and surgeon volumes was poor. Conclusion. We evaluated local quality indicators for an initial benchmark, and the most emergent gaps in care are the receipt of radiotherapy and underutilisation of sentinel node biopsy
