Baseline blood count levels increase odds of cytopenia among CML patients in Kenya: a case control study.

BACKGROUND: Imatinib is the gold standard for the treatment of all phases of Philadelphia positive Chronic Myeloid Leukemia (CML). During treatment, patients may develop cytopenia. We aimed to study the baseline characteristics and factors associated with cytopenia at a Nairobi Hospital. METHODS: This was a retrospective case-control study of patients aged ≥18 years on follow-up at the Glivec International Patient Access Program (GIPAP) clinic from 2007 to 2015. The cases consisted of CML patients on imatinib who developed cytopenia. The controls were CML patients on imatinib who did not develop cytopenia. Baseline socio - demographic, clinical, hematologic, and molecular data were retrieved from patients' files. Chi square or fishers' exact tests were used to analyze for differences between cytopenia and no cytopenia. Binary logistic regressions were employed to identify relationships. Univariate and multivariate analyses were done to identify independent predictors of cytopenia. Odds ratios (OR) were presented including the 95% confidence intervals and respective p values. RESULTS: A total of 201 patients were studied consisting of ninety-four (94) patients with cytopenia and 107 with no cytopenia. Among the entire population, males were 52, and 42% were aged 36-50 years. Sex, age, marital status, occupation and education level were similar between the cytopenia and no cytopenia groups. Among the 201 patients, 70% had symptoms for > 12 months before diagnosis, 78.6% had B symptoms at baseline, 80% had a moderate splenomegaly at baseline. Among patients with cytopenia, 40 and 37.4% developed cytopenia within 3 months and 3-6 months respectively after imatinib initiation. Baseline neutrophilia, neutropenia, anaemia, thrombocytosis, thrombocytopenia was found in 68, 11, 11, 23.5 and 11% respectively. Baseline hemoglobin, neutrophil and platelet level were significantly different between the cytopenia and the no cytopenia group. On univariable analysis, baseline anemia with hb < 7.9 g/dL (p = 0.002), neutropenia (p = 0.001), neutrophilia > 100,000/mm3 (p = 0.002) and thrombocytopenia (p = 0.001) increased the odds of developing cytopenia. On multivariable analysis, baseline anaemia (p value < 0.002), neutropenia (p value < 0.001), thrombocytopenia (p value, < 0.001) and thrombocytosis (p value, 0.033) increased the odds of developing cytopenia. CONCLUSION: Odds of cytopenia were higher in presence of baseline cytopenia and thrombocytosis. Clinicians should have a high index of suspicion for these patients.

Prevalence and Predictors of Cisplatin-Induced Peripheral Neuropathy at the Kenyatta National Hospital.

PURPOSE: To determine the prevalence, predictors, and/or risk factors of chemotherapy-induced peripheral neuropathy in patients undergoing chemotherapy with cisplatin at Kenyatta National Hospital, Nairobi, Kenya. METHODS: This was a cross-sectional analysis of patients who underwent chemotherapy with cisplatin for at least 2 months at Kenyatta National Hospital oncology units. Peripheral neuropathy was determined by history and physical examination per the protocol. Data are presented in tables. Descriptive inferential statistics such as means, medians, and proportions were determined where applicable. RESULTS: We recruited 67 patients who were undergoing chemotherapy with cisplatin. Fifty-six patients (83.6%) had peripheral neuropathy. Forty-five patients (81%) had mild-grade (grades 1 and 2) peripheral neuropathy. Only two patients (3.1%) had grade 4 neuropathy. Almost all patients who were overweight or obese developed peripheral neuropathy. CONCLUSION: Peripheral neuropathy among patients receiving cisplatin is quite prevalent at Kenyatta National Hospital (83.6% prevalence rate). However, most of the patients had a mild grade of neuropathy, which is largely consistent with literature elsewhere.

Improving Access to Cancer Testing and Treatment in Kenya.

PURPOSE: In response to the increasing cancer burden in Kenya, this study identified barriers to patients seeking access to cancer testing and treatment and to clinicians in delivering these services. Policy recommendations based on findings are presented. METHODS: This qualitative study used semistructured key informant interviews. Purposive sampling was used to recruit 14 participants: seven oncology clinicians and seven support and advocacy leaders for patients with cancer. Qualitative analysis was used to identify themes. RESULTS: Seven barriers to cancer testing and treatment were identified: high cost of testing and treatment, low level of knowledge about cancer among population and clinicians, poor health-seeking behaviors among population, long distances to access diagnostic and treatment services, lack of decentralized diagnostic and treatment facilities, poor communication, and lack of better cancer policy development and implementation. CONCLUSION: Kenyans seeking cancer services face significant barriers that result in late presentation, misdiagnosis, interrupted treatment, stigma, and fear. Four policy recommendations to improve access for patients with cancer are (1) improve health insurance for patients with cancer; (2) establish testing and treatment facilities in all counties; (3) acquire diagnosis and treatment equipment and train health personnel to screen, diagnose, and treat cancer; and (4) increase public health awareness and education about cancer to improve diagnoses and treatment. Effective cancer testing and treatment options can be developed to address cancer in a resource-constrained environment like Kenya. An in-depth look at effective interventions and policies being implemented in countries facing similar challenges would provide valuable lessons to Kenya's health sector and policymakers.

The American Society of Clinical Oncology's Efforts to Support Global Cancer Medicine.

Despite much progress in the management of malignant diseases, the number of new cases and cancer-related deaths continues to rise around the world. More than half of new cases occur in economically developing countries, where more than two thirds of cancer deaths are expected. However, implementation of all necessary steps to accomplish the dissemination of state-of-the-art prevention, diagnosis, and management will require increased allocation of resources, and, more importantly, harmonization of the efforts of hundreds of national and international public health agencies, policy-setting bodies, governments, pharmaceutical companies, and philanthropic organizations. More than 30% of the members of the American Society of Clinical Oncology (ASCO) reside and practice outside US borders, and more than half of attendees at all of the scientific congresses and symposia organized by ASCO are international. As cancer has become an increasingly global disease, ASCO has evolved as a global organization. The ASCO Board of Directors currently includes members from France, Brazil, and Canada. In 2013, the ASCO Board of Directors identified a number of strategic priorities for the future. Recognizing the importance of non-US members to the society, their first strategic priority was improving the society's service to non-US members and defining these members' identity in the international oncology community. This article reviews current ASCO activities in the international arena and its future plans in global oncology.

Oesophageal cancer and Kaposi's sarcoma in Malawi: a comparative analysis.

Given that oesophageal cancer (OC) is common in Malawi and its outcome is so dismal, would it be pragmatic to promptly mitigate the effects of smoking, alcohol and aflatoxins rather than seek a higher degree of local evidence for their role in OC? We retrospectively analysed a total of 13,217 OC and Kaposi's sarcoma (KS) cases as recorded in the Malawi National Cancer Registry from 1985 to February, 2006. We found no OC clustering to suggest a role for culturally variable habits like smoking, alcohol, maize use and maize storage in the country. It may be that drinking and eating hot foods physically damages the oesophageal mucosa, this is in line with work recently reported from Asia. We also found that OC numbers have risen in line with KS (and HIV) suggesting a link between these conditions.

The need for a national cancer policy in Malawi.

Cancer is causing a lot of suffering and death in Africa but is not considered a major health problem in Africa. This needs to change. Cancer should be given equal emphasis to HIV/AIDS, tuberculosis (TB) and Malaria. A national cancer policy is required in Malawi to develop and improve evidence-based cancer prevention, early diagnosis, curative and palliative therapy. A national cancer policy is crucial to ensure a priotised, clear, coordinated and sustained fight against cancer. When no policy exists, events are likely to be random, stakeholders and practitioners in the fight against cancer may not agree on how to proceed, may duplicate efforts or may neglect areas that would have greater nationwide impact resulting in poor quality activities and haphazard development.
