HIV and breast cancer – a mammographic analysis: An observational study to identify the mammographic pattern of breast cancer in HIV-positive patients

Background. Data on the association between HIV and breast cancer mammographic patterns and histological subtypes are limited.Objectives. To determine whether specific mammographic findings, histological features and patient profiles were unique to a cohort of HIV-positive patients who developed breast cancer, by comparing them with a HIV-negative cohort.Methods. This was a descriptive study in which we conducted a retrospective chart review and mammographic and pathology analysis of newly diagnosed breast cancer patients referred to the Addington Hospital breast clinic between August 2008 and June 2012 and entered into a prospective database.Results. Thirty-eight HIV-positive and 38 HIV-negative patients were included in the study. HIV-positive patients were more likely to have multifocal breast cancer (p=0.007), but not multicentric disease (p=0.05). The presence of grouped and fine pleomorphic microcalcifications and positive HIV status demonstrated statistical significance (p=0.000). A statistically significant relationship between grouped and fine pleomorphic microcalcifications with biopsies confirming high-grade ductal carcinoma in situ (HGDCIS) and HIV status was demonstrated (p=0.001). The mean age of the HIV-positive patients was 42.5 years (p=0.000).Conclusions. We demonstrated a statistically significant relationship between HIV status, the presence of multifocal breast cancer, and mammographically detected grouped and fine pleomorphic microcalcifications. A statistically significant relationship between HGDCIS and HIV status, and the presence of grouped and fine pleomorphic microcalcifications in HIV-positive patients with biopsies confirming HGDCIS, was demonstrated. Our study also showed that there is a relationship between age of presentation and HIV status.

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.

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

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Improving Outcomes in Breast Cancer for Low and Middle Income Countries

Breast cancer is the most common cancer in women world-wide. Incidence rates in low- and middle-income countries (LMICs) are lower than in high income countries; however, the rates are increasing very rapidly in LMICs due to social changes that increase the risk of breast cancer. Breast cancer mortality rates in LMICs remain high due to late presentation and inadequate access to optimal care. Breast Surgery International brought together a group of breast surgeons from different parts of the world to address strategies for improving outcomes in breast cancer for LMICs at a symposium during International Surgical Week in Helsinki, Finland in August 2013. A key strategy for early detection is public health education and breast awareness. Sociocultural barriers to early detection and treatment need to be addressed. Optimal management of breast cancer requires a multidisciplinary team. Surgical treatment is often the only modality of treatment available in low-resource settings where modified radical mastectomy is the most common operation performed. Chemotherapy and radiotherapy require more resources. Endocrine therapy is available but requires accurate assessment of estrogen receptors status. Targeted therapy with trastuzumab is generally unavailable due to cost. The Breast Health Global Initiative guidelines for the early detection and appropriate treatment of breast cancer in LMICs have been specifically designed to improve breast cancer outcomes in these regions. Closing the cancer divide between rich and poor countries is a moral imperative and there is an urgent need to prevent breast cancer deaths with early detection and optimal access to treatment
