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.

Apoptotic properties of Citrus sudachi Hort, ex Shirai (Rutaceae) extract on humanA549 and HepG2 cancer cells

Purpose: To investigate whether Citrus sudachi harvested at two stages of maturity can induce toxicity in a cell-specific manner and to determine the possible mechanisms of Citrus sudachi-induced cytotoxic responses in two types of cancer cells (human lung adenocarcinoma A549 and hepatocellular carcinoma HepG2 cells) and two normal cell lines (lung 16HBE140- and liver CHANG cells). Methods: 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and annexin V/propidium iodidle assay were used to test the antiproliferative activity and apoptosis of methanol extract of Citrus sudachi, respectively. Griess reaction and reverse transcriptase-polymerase chain reaction (RT-PCR) were carried out to evaluate nitric oxide (NO•) production and the mRNA levels of inhibitors of apoptosis (IAP). Results: Citrus sudachi exerted cytotoxicity in a time-dependent manner in cancer cells which increased with increase in maturity but did not affect normal cells. Citrus sudachi was found to induce accumulation of cells in the sub-G1 cell cycle phase, fragmentation of DNA and cell death with characteristics of apoptosis, in both types of cancer cells. Moreover, Citrus sudachi upregulated cellular NO• produced by activation of nitric oxide synthase (NOS), while it suppressed the levels of IAP mRNA in both types of cancer cells. Conclusion: The results obtained suggest that Citrus sudachi induces apoptosis in A549 and HepG2 cells, which may be mediated by NO•. There is need for further studies on the role of Citrus sudachi in cancer treatment.

Clinical Studies on conformal radiotherapy combined with epidermal growth factor receptor-tyrosine kinase inhibitor in second-line treatment of non-small cell lung cancer

Purpose: To study the effect of conformal radiotherapy combined with epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in the second-line treatment of non-small cell lung cancer (NSCLC). Methods: A total of 316 patients attending Shanghai Pulmonary Hospital affiliated to Tongji University, were divided into two groups: 106 patients were treated with conformal radiotherapy combined with EGFR-TKI (gefitinib, 250 mg/day; or erlotinib, 150 mg/day), while 210 patients were treated with EGFRTKI alone. Some factors, including adverse reactions (AR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and one-year and two-year survival rate, were evaluated. Results: No obvious difference was observed in AR between the two groups (p > 0.05). In the combination therapy group, complete response (CR) was 5 cases, partial response (PR) 43 cases, and stable disease (SD) 47 cases, progressive disease (PD) was 11 cases, response rate (RR) was 45.3 %, and DCR 89.6 %. Median PFS in the combination therapy group and targeted therapy group was 6.5 and 5.0 months, respectively. On the other hand, median OS in the combination therapy group and targeted group was 14.1 and 12.6 months, respectively. One-year survival rate of the combination therapy group and EGFR-TKI group was 60.3 and 50.0 %, respectively, while the two-year survival rate was 26.3 and 19.0 %, respectively. Conclusion: Conformal radiotherapy combined with EGFR-TKI can be used as an effective second-line treatment for NSCLC.

Clinical efficacy of paclitaxel in the treatment of mid-stage and advanced malignant gastric cancer, and effect of nursing interventions

Purpose: To investigate the clinical efficacy of paclitaxel combined with additional chemotherapy for mid-stage and advanced malignant tumors, and the benefits afforded by scientific nursing. Methods: Patients with mid-stage and advanced gastric cancer were randomly divided into test and control groups. Control group was given intravenous chemotherapy (400 mg/m2 fluorouracil and 2500 mg/m2 cisplatin) and nursed conventionally, while the test group was additionally treated with 80 mg/m2 paclitaxel and underwent special scientific nursing. Clinical effects and changes in the rates of apoptosis and cell proliferation were recorded. The effect of applying scientific nursing on therapeutic outcomes was also evaluated. Results: The overall rate of treatment effectiveness, clinical control rate, mean apoptosis and proliferation rates in the test group were 56.40, 92.30, (7.10 ± 3.17 and 28.70 ± 3.22 %, respectively, while, in the control group, the values were 38.50, 64.10, 25.40 ± 2.67 and 32.60 ± 2.93 %, respectively. The differences were all statistically significant (p < 0.05). In terms of nursing efficacy, the test group had a lower pain score and higher quality-of-life scores (Karnofsky performance status score) than control group. There was no significant difference in the incidence of adverse reactions between the two groups (p > 0.05). Conclusion: Paclitaxel has a significant effect when used to treat mid-stage and advanced gastric cancer. Moreover, additional nursing not only enhances the therapeutic effect but also improves prognosis and quality-of-life.

Healthcare providers’ knowledge, attitude and behaviour towards breast cancer diagnosis and treatment in Malaysia – a mini systematic review

Breast cancer is the most common cancer among women in Malaysia. Therefore, it is important for the public to be educated on breast cancer and to know the steps that need to be taken to detect it early. Healthcare providers are in a unique position to provide public health education due to their good knowledge of health issues and their roles in healthcare. A systematic review of studies conducted from 2008 till 2015 was undertaken to analyze the knowledge, attitudes and behavior of Malaysian healthcare providers regarding breast cancer, in an attempt to obtain an overall picture of how wellequipped the healthcare providers are to provide optimal breast cancer education, and to ascertain their perceptions and actual involvement in such education. The systematic review was conducted via a primary search of various databases and journal websites, and a secondary search of references cited in eligible studies. Criteria for eligibility include studies conducted in Malaysia and published from the year 2008 to 2015, and written in English language. A total of fifteen articles were identified and reviewed but only two studies were eligible for this review. The findings suggest that future and current Malaysian healthcare providers have moderate knowledge of breast cancer, showed a positive disposition towards involvement in breast cancer education, but displayed poor involvement.
