RESUMEN

PURPOSE: An understanding of the cultural and context-specific perceptions of the causes of cancer is an important prerequisite for designing effective primary health prevention and early detection strategies. We aimed to use the Murdock Ill Health Theoretical Model to conceptualize views on illness causation among dysphagia-suffering patients undergoing diagnostic workup for esophageal cancer (EC) in Tanzania. METHODS: At the end of a structured interview on lifestyle habits, patients with suspected EC were asked about beliefs on the reasons behind their illness through (1) a set of questions with fixed binary answers, whose determinants were analyzed using logistic regression, and (2) a single question with free-text answers. Responses were coded using a hierarchy of natural and supernatural (godly and social constructs) causes. RESULTS: Among 322 patients interviewed between November 2015 and December 2019, we found complex and varied views about the origins of their illness. Overall, 49% of patients attributed illness to natural causes and 39% to supernatural causes. Natural causes ranged from infection, use of alcohol and tobacco, other ailments, and the environment. The supernatural causes included attributing illness to God, curses, and spells from personal acquaintances. Belief in supernatural causes was more common in the less educated and those who sought help first via a traditional healer. CONCLUSION: The results underscore the need for increased community awareness of biomedical causes of ill health and patient-based participatory research to inform prevention programs. The results also highlight the importance of building health systems that support a series of health-seeking behaviors that acknowledge both biomedical and local traditional healing belief systems.

RESUMEN

BACKGROUND: The purpose of this study was to assess willingness of advanced cancer patients to receive palliative care and its determinants at Cancer Care Centre in Kilimanjaro Christian Medical Centre Northern Tanzania. OBJECTIVE: The purpose of this study was to assess willingness of advanced cancer patients to receive palliative care and its determinants at Cancer Care Centre in Kilimanjaro Christian Medical Centre Northern Tanzania. METHODS: This was an institution-based cross-sectional study and the target population was all advanced cancer patients attending care at Cancer care Centre in Northern Tanzania. Data was collected using a structured questionnaire and analysed using Stata for windows 15. A descriptive analysis was conducted to summarize the data using mean standard deviation, while categorical data was summarized using frequency and percentages. Both bivariate and multivariate logistic regression analysis was used to determine the predictors associated with willingness to receive palliative care. RESULTS: The results showed that more than half of the respondents had willingness to accept palliative care. The degree of willingness PC among advanced cancer patients was high 60.6% (95%CI: 55.8-65.3). The predictors which remained significant associated with willingness to receive palliative care in multivariate analysis were the knowledgeable of palliative care [AOR: 2.86; 95%CI: 1.69-4.85] and high perceived benefits of palliative care [AOR: 3.58; 95%CI: 2.12-6.04]. CONCLUSION: Willingness to accept palliative care services was more than half of the patients just 60.6% among patients with advanced cancer from the study site. Advanced age of a patient, occupations, better knowledge, and perceived benefits for palliative care was the significant predictor for patients' willingness to accept palliative care.

RESUMEN

INTRODUCTION AND IMPORTANCE: Brain metastasis is the most common associated consequence of primary lung cancers, and it has a major detrimental influence on patients' survival and quality of life. Modern imaging modalities such as brain MRIs and PET scans are preferred for assessing these lesions. Complete surgical resections have been shown to enhance survival. CASE PRESENTATION: We present the case of a 59-year-old male patient who had a history of progressive left-sided weakness and right-sided headaches with no respiratory symptoms. A solitary brain lesion was noticed, prompting a surgical resection. Histology findings confirmed brain metastases, and a thoracic CT scan revealed a primary lung tumour. The patient was scheduled for chemotherapy. DISCUSSION: Primary lung tumors often disseminate to the brain. The brain metastatic lesions in advanced lung cancer are often numerous and smaller in size, based on MRI imaging. The patient's symptomatology obscured the existence of an underlying lung tumour, delaying focused therapy. The early symptomatology and scans of our patient indicated the probability of a solitary brain tumour, necessitating a surgical excision. CONCLUSION: Prompt management of brain metastatic lesions is crucial. Yet, some patients emerge with atypical characteristics of the lesions that hint to a primary brain lesion and conceal the presence of a lung tumour. Enhancing these patients' prognoses necessitates a targeted therapy that includes a comprehensive examination, radiological imaging, and recognition of the distinctive brain patterns in patients with lung cancer. The merits of complete or incomplete resections for multiple brain metastatic lesions might be a fascinating subject of discussion.

RESUMEN

Breast cancer is the most frequent cancer in women in Africa and contributes to premature death and poor quality of life. This study aimed to determine the validity, reliability, and psychometric properties of the Swahili version of EORTC QLQ-BR45 among women with breast cancer in Tanzania. A cross-sectional study design with non-probability convenience sampling was employed. Data were collected in two tertiary hospitals and one national cancer institute; 414 participants completed the EORTC-QLQ-C-30 and EORTC-QLQ-BR45. The reliability of QLQ-BR45 was measured using Cronbach's alpha and McDonald's Omega coefficients. The factor structure of EORTC QLQ-BR45 was assessed using confirmatory factor analysis. The internal consistencies for the five dimensions were all above 0.7 indicating satisfaction, except for systemic therapy side effects with a marginal value of 0.594 and significant correlations between the dimensions of QLQ-C30 and BR45. The final model fit well to the data, with the comparative fit index = 0.953, Tucker-Lewis index = 0.947, root mean square error of approximation = 0.041 (90% CI: 0.035, 0.046), and standardized root mean square residual = 0.072. In conclusion, the QLQ BR45 Swahili version displayed good reliability, validity, and psychometric properties and can be used in Swahili-speaking Sub-Saharan countries.

RESUMEN

Introduction: Breast cancer is increasing in sub-Saharan Africa (SSA), and most women are diagnosed at a late stage. This leads to increased suffering for the patients and challenging care situations for nurses. Limited resources in healthcare, lack of oncology training, and low health literacy in society result in even more demanding situations for nurses. Objective: The objective was to explore nurses' experiences of caring women for with breast cancer in Tanzania. Methods: The study employed a descriptive qualitative design. Fifteen nurses, working in oncology units in three major hospitals in Tanzania were interviewed using a semistructured interview guide. The participants had a minimum of 6 months experience of caring for breast cancer patients. Purposive sampling was used. Data were analyzed by qualitative content analysis. Results: Two main themes emerged: Challenges in caring for breast cancer patients and Nurses' psychological distress. The late diagnosis was very challenging for the nurses. Low health literacy regarding breast cancer disease and treatment, patients' financial difficulties, minimal oncology nursing education, and technology in healthcare systems were also major challenges. The nurses experienced psychological distress, lost hope, and faced ethical dilemmas while providing cancer care. Conclusion: The findings of this study conclude that nurses face emotional distress and ethical dilemmas while caring for patients with breast cancer. Late diagnosis, lack of infrastructure and resources, and low health literacy among patients, family, and healthcare providers have a great impact on the stress that the nurses experience.

RESUMEN

Key Clinical Message: Primary SCC of the breast is a very rare disease.Metastasis from elsewhere should be excluded first.The tumor is a very aggressive with poor prognosis.No standard treatment approaches are available.Managed by surgical excision followed by chemotherapy and radiotherapy. Abstract: Primary squamous cell carcinoma of the breast is an exceedingly rare disease, and its management is still unclear. A-65-year-old lady presented with a progressive swelling of her right breast that started spontaneously. Other potential primary sites were ruled out. She was kept on a neo-adjuvant chemotherapy (AC-T protocol) of doxorubicin, adriamycin, and paclitaxel. Later, she was underwent modified radical mastectomy with axillary lymph node dissection. Her post-operative recovery was uneventful. Currently, she is followed up at oncology outpatient clinic.

RESUMEN

OBJECTIVE: To ascertain how the COVID-19 pandemic was perceived by oncology patients and community health workers (CHWs) and whether this contributed to disruptions in cancer care. DESIGN: Cross-sectional study using (1) structured telephone interviews with patients and (2) structured questionnaires completed by CHWs. SETTING: Outpatient and community care at Kilimanjaro Christian Medical Centre's Cancer Care Centre (KCMCCCC), Northern Tanzania. PARTICIPANTS: 300 oncology patients (158 men and 142 women) who had attended KCMCCCC between January and April 2020 and 78 CHWs (16 men and 62 women) in the KCMC regional palliative care network who conducted home visits to patients with cancer during the period January to April 2020. PRIMARY OUTCOME MEASURES: For patients, missed appointments and fear of COVID-19 more than postponement of their treatment. For CHWs, no primary outcome (a broad range of questions on perception of the pandemic were asked). RESULTS: 30% of patients said they missed appointments due to the pandemic, the most commonly cited reasons being financial problems (37%) and fear of acquiring COVID-19 infection during travel and/or in the hospital (37%). Only 12.7% of patients said they feared COVID-19 more than postponement of cancer treatment. 88% of CHWs noticed differences in delivering home care since the start of the pandemic, with 58% saying they had noticed more patients dying and 74% saying that more patients were relying on local healers. 31% of CHWs said they feared home visits because of COVID-19 and 46% perceived patients feared home visits due to COVID-19. However, 92% felt home visits should continue. CONCLUSION: These results indicated that while there was a significant degree of disruption and fear around the COVID-19 pandemic, the majority of patients and CHWs did not fear of COVID-19 more than disruption to cancer care. This highlights the importance to these groups of maintaining access to vital cancer services.

RESUMEN

PURPOSE: Challenges to breast cancer control in low-and middle-income countries exist because of constrained access to care, including pathology services. Immunohistochemistry (IHC)-based estrogen receptor (ER) analysis is limited-nonexistent because of few and inadequately staffed and equipped pathology laboratories. We have identified Nw-hydroxy-L-Arginine (NOHA) as a blood-based biomarker to distinguish ER status in US patients with breast cancer. Here, we examine NOHA's clinical utility as an ER IHC alternative in Tanzanian patients. MATERIALS AND METHODS: Following informed consent, 70 newly diagnosed, known or suspected patients with breast cancer were enrolled at Kilimanjaro Christian Medical Center; basic, deidentified clinical and sociodemographic data were collected. For each, a needle prick amount of blood was collected on a Noviplex plasma card and stored at -80°C. Plasma cards and unstained tumor pathology slides were shipped regularly to US laboratories for NOHA, histologic and IHC analysis. NOHA and IHC assay operators were blinded to each other's result and patient clinical status. Paired NOHA and IHC results were compared. RESULTS: Slides from 43 participants were available for pathological analysis in the United States. Of those with confirmed malignancy (n = 39), 44%, 51%, 5% were ER-positive, ER-negative, and ER inconclusive, respectively. NOHA levels were available among 33 of 43 of those with pathological data and showed distinct threshold levels correlating 100% to tumor ER IHC and disease categorization where a level below 4 nM, from 4 to 8 nM, and above 8 nM signified ER-negative, ER-positive, and no cancer, respectively. CONCLUSION: The results are consistent with findings from US patients and suggest NOHA's clinical utility as an accessible IHC replacement in determining ER status among low-and middle-income country patients with breast cancer, promising to extend access to cost-efficient, available hormonal agents and improve outcomes.

RESUMEN

PURPOSE: Breast cancer (BC) is the second most common cancer among Tanzanian women. Oestrogen (ER), progesterone and human epidermal growth factor receptor 2 play major roles in prognosis and treatment but data for Tanzania are sparse. This study aimed to determine these patterns and histological types, tumour grading and staging of BC patients in northern Tanzania for a better understanding of BC in the Sub-Saharan African (SSA) setting. METHODS: A cross-sectional study recorded newly diagnosed BC cases at Kilimanjaro Christian Medical Centre between October 2018 and March 2019. Receptor status, histological types and grade, clinical stage and socio-demographic were recorded and descriptive and bivariate analyses performed. RESULTS: 116 patients were enrolled. Median age was 53 years, 71.6% were ≥45 years. The commonest molecular subtype was triple negative breast cancer (TNBC) (n = 33; 28.4%). One hundred and two (87.9%) patients had invasive ductal carcinoma (IDC), poorly differentiated tumours (60; 51.7%) and clinical stage III disease (62; 53.0%). ER negative tumours were associated with poorly differentiated histological grade (relative risk (RR): 1.34 (0.87-2.07)), tumour size > 5 cm (RR: 1.67 (0.33-8.35)) and IDC (RR: 3.35 (0.56-20.23)). Clinical stages III & IV (odds ratio (OR): 1.64 (0.63-4.24)) were associated with hormone receptor (HR) negative tumours and metastasis (OR: 1.60 (0.68-3.74)) with TNBC. 18% of the patients reported about first-degree relatives with BC. CONCLUSIONS: Most patients presented in advanced stages and TNBC in their menopause. HR negative tumours were associated with poor histological differentiation and IDC. The high percentage of positive family history of BC and the differences in receptor patterns compared to other parts of the world should urge further genetic research on BC in SSA.

RESUMEN

PURPOSE: Cancer is a growing problem in Africa, and delays in receiving timely cancer care often results in poorer outcomes. The purpose of this study was to identify the patient and health-system factors associated with delayed cancer care in adults living in the Northern Zone of Tanzania. PATIENTS AND METHODS: Between July 2018 and July 2019, we surveyed adult patients presenting to an oncology clinic in Northern Tanzania. Delayed presentation was defined as 12 weeks or longer from initial symptoms to presentation for cancer care. Multivariate logistic regression and adjusted relative risk (aRR) were used to identify factors predicting delayed presentation. RESULTS: Among 244 adult patients with cancer who completed the survey, 78% (n = 191) had delayed presentation. Patient-related factors associated with delayed presentation included lower educational attainment (P = .03), increased travel time (P = .05), lack of cancer knowledge (P < .05), and fear of cancer and cancer treatments (P < .05) on multivariate analysis. On analysis of aRR, patients without private car and those with health insurance had higher risk of delayed presentation (aRR: 1.27; 95% CI, 1.02 to 1.32 and aRR: 1.15; 95% CI, 1.01 to 1.32). There was a strong association with increased number of visits before presentation at the cancer center and delayed presentation (P = .0009). CONCLUSION: Cancer awareness and prevention efforts targeting patients and community-level health care workers are key to reduce delays in cancer care in Northern Tanzania.

RESUMEN

Background: 14.9 million women (≥15 years) in Tanzania are at risk of developing cervical cancer. Limited cancer care facilities, prevention programs and sparse knowledge among community members and healthcare workers contribute to late-stage presentation leading to a high mortality rate. Objective: This study aims to scientifically accompany prevention and awareness campaigns (PrevACamp) in northern Tanzania in its real-world settings to obtain (1) a better understanding about cervical cancer and HPV knowledge amongst female PrevACamp participants and (2) to determine the prevalence of pre-cancerous lesions among women undergoing cervical cancer VIA screening. Method: Cross-sectional survey among PrevACamp attendees in two regions in Northern Tanzania. Two data collections tools were used: Questionnaires and clinical data from VIA screening. Data were collected from October 2017 to March 2019. Results: 2,192 PrevACamp attendees were interviewed and 2,224 received VIA screening. There was significant nescience on cervical cancer regardless of education level, resident status, or number of children as well as nescience on HPV in all age groups, especially in urban areas and misconceptions about cancer. Screening revealed VIA positivity rate of 3.1%. Conclusion: There is an alarming lack of knowledge about cervical cancer and, to a lesser Extent, about HPV among the study participants. Having health insurance influenced the level of knowledge significantly. Outreach programs in rural areas appear to target the population in need of health education. Low positive VIA screening results are paralleled with lower HIV rates among the women. We assume that the high density of primary health care coverage in northern Tanzania contributes to these findings..

RESUMEN

Cancer is a growing burden in Tanzania with high mortality rates. Low level of cancer awareness in the population and health workforce is one of the reasons. This study aimed to evaluate the effects of a cancer awareness training for community-level healthcare providers in Kilimanjaro Region. Main research interest was to assess the effects of the training on cancer knowledge of the healthcare workers and its application into practice. Community health workers (CHWs) (n = 25) and dispensary healthcare workers (DHCWs) (n = 16) attended cancer awareness trainings. Three training days over a 3-month period were provided for each group. Pre- and post-training assessments of the cancer knowledge were conducted on each training day. Application of the knowledge into practice was assessed at follow-up and complemented with qualitative data. Analysis of the questionnaires was provided by descriptive statistics. Qualitative data were analyzed by semantic thematic analysis. Both groups showed a statistically significant increase in knowledge after the three training days: CHWs + 10% (CI 95% = 2-18%, p = 0.015) and DHCWs 24.4% (CI 95% = 13-36%, p = 0.002). The community-level healthcare providers also started to apply the new cancer knowledge into practice and reported to feel more confident in cancer control. The pilot cancer awareness training was effective in increasing cancer knowledge and its application. It strengthened their confidence in care delivery and referral practices as well as education of the population. This concept of cancer awareness training might be also applicable to other countries in SSA.

RESUMEN

PURPOSE: A trend of increasing incidence of colorectal cancer (CRC) has been observed in northern Tanzania. Studies have shown a six-fold increase in CRC in the past decade, with 90% of patients presenting in late stages, with resultant high morbidity and mortality rates. In this study, we aimed to document the burden of CRC in the northern zone of Tanzania from 1998 to 2018, focusing on patient presentation, clinical features, and treatment at a tertiary hospital. METHODS: Pathological and clinical records for all patients from 1998 to 2018 were identified and reviewed. Records of patients whose CRC was diagnosed histologically were retrospectively reviewed. RESULTS: Approximately 313 CRC cases were documented. The majority age group (29.1%) was between 50 and 64 years (mean [standard deviation], 54.28 [16.75] years). However, together, the age groups of patients younger than 50 years was 41.5% (n = 130). Of 174 patients with complete records, most (29.3%) were between 35 and 49 years of age. The median age was 52 (interquartile range, 40-67) years. Men accounted for 62.1% of patients and were mostly from the Kilimanjaro region. More than half (54.7%) presented > 3 months after symptom debut; 62.6% first sought care at lower-level health facilities. Most (64.9%) presented as emergencies, necessitating colostomy for fecal diversion as the initial surgical procedure in 60.3% of patients. Colonoscopy was performed for 38.6% of the study participants. Most tumors (72.7%) originated from the sigmoid and rectum. Adenocarcinoma was the most prevalent histologic type. CONCLUSION: High proportions of young individuals with CRC pose great concern and a need for further appraisal. Furthermore, late emergency presentation and low colonoscopy rates highlights underlying system challenges and need for education campaigns.

RESUMEN

PURPOSE: Cancer is a growing public health concern in low-income countries (LICs). From 14 million new patient cases identified worldwide each year, 8 million are diagnosed in LICs. The fatality rate is 75% in LICs compared with 46% in high-income countries. Causes are low literacy levels, lack of awareness and knowledge about cancer, and limited education of health care professionals that leads to late detection and diagnosis. In Tanzania, cancer incidence will double to 60,000 in 2030. The referral hospital of Northern Tanzania established a new cancer unit in December 2016 to meet these needs. However, there is limited knowledge about perceptions of health care professionals toward cancer care in LICs. This study aims to understand attitudes and perspectives of those professionals and the treatment-related challenges in a newly established center to assist future efforts in this field. METHODS: A qualitative method approach using in-depth interviews was chosen to achieve inductive conceptualization. Analysis of data was performed according to qualitative content analysis. RESULTS: Eleven interviews were conducted. Five main categories were found: training and education of staff, availability of financial support, challenges in management, interests in future developments, and job satisfaction. Subcategories elaborated in more detail within the main categories. CONCLUSION: Limitations in staffing, training, and education were major concerns. The importance of sustainable funding and the needed cooperation of the government with international aid were identified as key points. The involvement of different stakeholders requires guidance by health care management. Health care professionals expressed their satisfaction with the possibilities of treating cancer and the rewarding feedback from patients. Misconceptions and poor knowledge by patients were mentioned as reasons for delayed health-seeking behavior. Screening and awareness programs were seen as useful interventions.
