Global Burden of Cancer
• A Leading cause of morbidity and mortality
worldwide
– Annual incidence estimated at 10 million
• Accounted for 7.9 million deaths in 2009
– > 70% of all cancer deaths occur in low and
middle-income countries
• By 2030, cases and deaths will increase by
69% and 72% respectively
•
•
•
•
•
Cancer in Kenya
Ranked 3rd leading cause of death
Causes 7% of total national mortality every year
Annual incidence ~28,000 cases
Annual mortality >22,000
Only two population-based registries exist
(regional)
• National cancer control strategy (2011-2016)
developed
– Strengthen cancer prevention and control in
various sectors
– Investment in cancer awareness, human
resource, equipments, surveillance and
research
Justification
• Comprehensive data on the burden and
trends of cancer lacking in most sub Saharan
Africa
• Data on cancer in Kenya are limited yet
research is a key pillar in the national cancer
control strategy
• No similar studies have been published in
Central Kenya
Objectives
– To determine the various types of cancers
in patients attending Nyeri Hospice in
Central Kenya
– To characterize the cases in time, place and
person
Study Site
• Nyeri hospice, Nyeri
county, Central-Kenya
• Started in 1995
• Caters for cancer
patients
• Offers pain relief and
treatment of
opportunistic infections
Study Design
• Retrospective descriptive study
– We reviewed patients files and registers for a
two year period
– New cancer cases registered between Jan 2011
and Dec 2012 were identified and extracted
• Study population: Cancer patients attending
Nyeri hospice for palliative care
• Case definition: A reported diagnosis of cancer
at any age admitted to Nyeri hospice between
Jan 2011 and Dec 2012 for palliative care
Data Management
• Data collection
– Socio-demographic and cancer data were
abstracted from registers and files using a
standardized form
• Data entry and cleaning
– Epi info version 3.5.4 software and Ms Excel 2007
used
• Data analysis
– Means ,medians, proportions and frequencies
calculated for categorical and continuous variables

Discussion
• Cancer are an important public health
problem in this region
– Breast and cervical cancer main cancers in
women
• The study showed low levels of pathological
diagnosis(fifty-percent)
– Inadequate diagnosing capacity
• Lung cancer was not among the top ten
cancers
– Potential deficiencies in diagnosis
Conclusion
• Oesophagus, stomach and prostate were the leading
cancers in men.
• Commonest cancers among females were breast, cervix and
oesophagus
• Short median duration from diagnosis to death (95 days)
indicates late diagnosis
Recommendations
• Scaling up of cancer screening programs to enhance early
diagnosis
• Improve on recording at the hospice to guarantee data quality
• Public awareness on cancer prevention & control
• Strengthened diagnosing capacity
• Further epidemiological studies in cancer prevention and
control
