Experiences of patients undergoing chemotherapy - a qualitative study of adults attending Uganda Cancer Institute

Background: Cancer is a global public health challenge and how patients in countries with poor healthcare infrastructure experience cancer treatment is largely unknown. Purpose: The objective of this study was to describe adult Ugandan cancer patients’ experiences of undergoing chemotherapy treatment. Methodology: Using a qualitative descriptive design, seven in-patients with varying cancer diagnoses at the Uganda Cancer Institute were interviewed about their experiences of undergoing chemotherapy treatment; the interviews were transcribed and analysed thematically. Results: The analysis resulted in nine subthemes, which were categorized under three main themes: ‘experiences related to the body’, with the subthemes dry and sensitive skin, changes in eating and bowel habits, fever and feelings of abnormal body sensation; ‘thoughts and feelings’, with four subthemes reflecting the psychosocial impact of chemotherapy; and ‘actively dealing with discomfort’, with three subthemes describing how patients dealt with side effects, such as by sticking to a diet. Conclusion: Receiving chemotherapy treatment is difficult, and the side effects negatively influenced patients’ bodies and moods. Dealing actively with discomfort and accepting negative impacts in hope of a cure helped the participants manage the acute complications related to the treatment. We recommend the development of interventions to ease discomfort due to chemotherapy.

Levels of some heavy Metals in Cocoyam ( Colocasia esculentum ) grown on Soil receiving Effluent from a Paint Industry

The levels of some heavy metals in soil samples and tubers of cocoyam ( Colocasia esculentum ) grown on soil receiving paint wastes (PWS) has been investigated using Atomic Absorption spectrophotometer (Unicam 939/959 model). Similar analyses were carried out for the same plant from a control area. The studies revealed that although the P.W.S contained abnormally high levels of Pb (474.14mgkg-1) and Cu (137.85mgkg-1). The paint waste tuber (PWT) recorded low levels of these metals: Pb (2.13mgkg-1) and Cu (13.85mgkg-1) respectively. Correlation analysis tested at 0.05 level of significance show that no significant correlation existed between the metals levels in the soil and the level in the tuber. In all cases the levels of the metals in the tubers were well below the upper limit documented for unpolluted plant. The results however suggest the ineffectiveness of the use of Colocasia esculentum as a bioindicator for heavy metal pollution in soil.

Neoadjuvant chemotherapy in Albinos with locally advanced skin cancer at a Blantyre Hospital: - Case Series

Albinism in Africa remains a public health concern with increasing numbers of advanced skin cancer in this population at presentation. There are challenges with availability of Radiotherapy (RT) units in Africa which is an important modality for controlling loco-regional disease alone or in combination with surgery. Proposed chemotherapy regimens have not been well validated through Randomized Controlled Trials thus posing difficulties for standard of care for units that do not have access to functional RT facilities. Malawi is one such country without radiotherapy. Case summary Seven patients with locally advanced skin cancer were seen in the adult oncology unit at Queen Elizabeth Central Hospital in Blantyre (QECH), Malawi between 2010 and 2013. QECH is one of the teaching hospitals in the country. All were subjected to neo-adjuvant chemotherapy. The primary treatment aim was cyto-reduction followed by surgery whilst the secondary outcome was general symptom control. Three patients achieved complete responses of which two underwent resection and a pectoralis major myocutaneous flap. One had a near complete response and three showed partial responses. Conclusion Neo-adjuvant chemotherapy may be a possible.

Efficacy of Preoperative Chemotherapy in Treatment of Children With Wilms’ Tumor: A Meta-Analysis

Context: To assess the efficacy of preoperative chemotherapy in Wilms’ tumor patients and explore its true value for specific subgroups. Objectives: In the presence of these controversies, a meta-analysis that examines the efficacy of preoperative chemotherapy in Wilms’ tumor patients and specific subgroups is needed to clarify these issues. The objective of this meta-analysis is to assess the efficacy of preoperative chemotherapy in Wilms’ tumor patients and explore its true value for specific subgroups. Data Sources: Computer-based systematic search with “preoperative chemotherapy”, “Neoadjuvant Therapy” and “Wilms’ tumor” as search terms till January 2013 was performed. Study Selection: No language restrictions were applied. Searches were limited to randomized clinical trials (RCTs) or retrospective studies in human participants under 18 years. A manual examination of references in selected articles was also performed. Data Extraction: Relative Risk (RR) and their 95% Confidence Interval (CI) for Tumor Shrinkage (TS), total Tumor Resection (TR), Event-Free Survival (EFS) and details of subgroup analysis were extracted. Meta-analysis was carried out with the help of the software STATA 11.0. Finally, four original Randomized Clinical Trials (RCTs) and 28 retrospective studies with 2375 patients were included. Results: For preoperative chemotherapy vs. up-front surgery (PC vs. SU) group, the pooled RR was 9.109 for TS (95% CI: 5.109 - 16.241; P < 0.001), 1.291 for TR (95% CI: 1.124 - 1.483; P < 0.001) and 1.101 for EFS (95% CI: 0.980 - 1.238; P = 0.106). For subgroup short course vs. long course (SC vs. LC), the pooled RR was 1.097 for TS (95% CI: 0.784 - 1.563; P = 0.587), 1.197 for TR (95% CI: 0.960 - 1.493; P = 0.110) and 1.006 for EFS (95% CI: 0.910 - 1.250; P = 0.430). Conclusions: Short course preoperative chemotherapy is as effective as long course and preoperative chemotherapy only benefits Wilms’ tumor patients in tumor shrinkage and resection but not event-free survival.

Can Fluorine-18-Fluorodeoxyglucose Positron Emission Tomography Be Used As a Useful Method to Evaluate the Treatment Response to Neoadjuvant Therapy Combined With Sorafenib and Anti-VEGF in Children Diagnosed With Metastatical Bone Sarcoma?

Background: The prognosis is still poor for patients with a metastatic bone tumor and new treatment approaches (anti-VEGF and tyrosine kinase inhibitors vs) are therefore needed. Objectives: The aim of our study was to evaluate how the primary and metastatic lesions of our patients with a bone tumor were affected by these treatments and to determine the importance of the 18F-FDG PET method. Patients and Methods: Twenty metastatic bone tumor cases were included. Sorafenib and anti-VEGF were added to the standard treatment in cases with widespread metastatic disease at diagnosis or after neoadjuvant chemotherapy showing less than 90% tumor necrosis in the surgical sample. Positron emission tomography (PET) imaging was performed at diagnosis, the preoperative period following neoadjuvant chemotherapy, during postoperative follow-up, and when treatment was discontinued. Results: The primary treatment region median SUVmax level decreased from 7.35 to 2.5 in the living patients (n = 16) while there was no significant decrease in the patients who succumbed to the disease (P < 0.001). Comparison of the pre- and post-treatment metastasis region median SUVmax levels in patients with metastatic involvement showed a decrease from 2.1 to 0 in the surviving patients but only from 4.8 to 3.2 in the deceased patients (P < 0.01). Survival results indicated that 28.6% of the patients receiving classical treatment only died while all the patients receiving additional sorafenib and anti-VEGF survived. Conclusions: 18F-PET may be a useful technique before and during the follow-up of neoadjuvant treatment in pediatric metastatic bone tumor patients. The addition of sorafenib and anti-VEGF to classical treatment has a favorable contribution to the response and therefore the survival duration.
