“…In contrast, what we have observed among BC cases in TT is that both incidence and mortality rates were highest among women of African descent. Similar findings were observed by Dindyal et al [24], who analyzed data from the Port of Spain region of TT specifically and found that the largest proportion of BC was diagnosed among women of African descent (54%) followed by women of Indian descent (35%) and mixed ancestry (11%). Some studies have suggested that differences in BC incidence and mortality are related to factors related to socioeconomic status and/or inequity in healthcare access and utilization [25][26][27][28][29].…”

Breast cancer (BC) is the most common newly diagnosed cancer among women in Trinidad and Tobago (TT) and BC mortality rates are among the highest in the world. Globally, racial/ethnic trends in BC incidence, mortality and survival have been reported. However, such investigations have not been conducted in TT, which has been noted for its rich diversity. In this study, we investigated associations among ancestry, geography and BC incidence, mortality and survival in TT. Data on 3767 incident BC cases, reported to the National Cancer Registry of TT, from 1995 to 2007, were analyzed in this study. Women of African ancestry had significantly higher BC incidence and mortality rates (Incidence: 66.96; Mortality: 30.82 per 100,000) compared to women of East Indian (Incidence: 41.04, Mortality: 14.19 per 100,000) or mixed ancestry (Incidence: 36.72, Mortality: 13.80 per 100,000). Geographically, women residing in the North West Regional Health Authority (RHA) catchment area followed by the North Central RHA exhibited the highest incidence and mortality rates. Notable ancestral differences in survival were also observed. Women of East Indian and mixed ancestry experienced significantly longer survival than those of African ancestry. Differences in survival by geography were not observed. In TT, ancestry and geographical residence seem to be strong predictors of BC incidence and mortality rates. Additionally, disparities in survival by ancestry were found. These data should be considered in the design and implementation of strategies to reduce BC incidence and mortality rates in TT.

“…In their article, they state that 'data were obtained from y 191 White British women', but in their reply to Dindyal et al (2008), they say 'all White women included reported themselves to be White English, Welsh or Scottish or White Irish' (my italics). I have assumed that the second statement is more accurate and that White Irish patients were included.…”

“…To sum up: in view of the concern their study has given rise to, it would seem highly advisable for the authors to reanalyse their data, taking care to match their categories as accurately as possible with those used in the census data and paying attention to the points raised by Dindyal et al (2008) and Cichowska et al (2008). …”

“…Between 2002 and 2004, invasive ductal carcinoma was the most commonly occurring histologic type (70%; n = 299), with invasive lobular carcinoma accounting for 17%, which was unusually high compared to the global prevalence of invasive ductal carcinoma (≤4%) at the time [ 65 ]. Afro-Caribbean women were twice as likely to develop invasive ductal carcinoma and invasive lobular carcinoma compared to Indo-Caribbean women [ 65 , 83 , 84 ]. Consistent with global trends, subsequent studies over the years continue to realize dominant ductal carcinomas (NOS and infiltrating/invasive types) among BC cases [ 44 , 46 , 47 , 64 , 85 ].…”

Breast cancer (BC) is one of the leading causes of death among women globally. In the Caribbean, there is a higher mortality rate compared with North American and European countries which have higher incidence rates. We conducted a literature review to examine the BC dynamic in the Caribbean and determine the areas where further investigations are needed. The PubMed database was used for identifying relevant studies using a combination of specific keyword searches. All studies focusing on BC within the defined Caribbean population were selected for this review. A total of 117 papers were included. The data were organized and presented under the following headings and reported according to the country where available: BC incidence and mortality, patient demographics, clinicopathology, genetics, behavioral risks, diagnosis and treatment, and BC control. Our review uncovered major variability in the incidence, management, etiology, and mortality of BC among Caribbean countries. Low-resource countries are burdened by more advanced disease with expected poorer BC outcomes (i.e., shorter periods of disease-free survival). Countries with established national cancer registries seem to have a better approach to the management of BC. The introduction of cancer treatment programs in association with international nonprofit groups has shown tremendous improvement in quality, accessible cancer care for patients, particularly in low- and middle-income settings. BC research is relatively limited in the Caribbean, lacking in both scope and consistency. The unique Caribbean BC population of diverse ethnicities, environmental influence, immigrants, socioeconomic status, and sociocultural practices allows an optimal opportunity for epidemiological investigations that can provide deeper insights into the status of BC.
