Anxiety and depression in patients with haematological neoplasms in Malaysia.

BACKGROUND: It is not uncommon that anxiety and depression occur in patients with cancers, and past researches have shown that the quality of life of patients is negatively affected. This study aims to determine the prevalence of anxiety and depression of patients with haematological cancers in Malaysia and to investigate the possible association of these psychological symptoms with their quality of life. METHODS: This is a cross-sectional study where patients with haematological cancers attending two major hospitals were recruited. Anxiety and depression symptoms were assessed using the Hospital Anxiety and Depression scale (HADS). Quality of life (QoL) of these patients was measured using the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ C30). An overall summary QoL score in combination with financial difficulty score and global health score were used for analysis. RESULTS: A total of 319 patients were recruited. Thirty-three percent of patients had anxiety symptoms, 23.5% had depression symptoms. In summary the overall score of QoL is significantly lower in patients with higher scores for depression and anxiety, (p<0.05). Patients who exhibit anxiety symptoms were more frequently female, still undergoing treatment whereas patients who had higher depression scores were older and had acute leukemias or myeloproliferative neoplasms. Patients who have depression are significantly associated with a higher financial difficulty score, p<0.05. CONCLUSION: The poor quality of life in patients who have anxiety and depression should raise awareness amongst the health professions treating them so that additional support can be provided.

Influence of genetic polymorphisms of cytokine genes in the outcome of HLA-matched allogeneic stem cell transplantation in a South East Asian population.

Non-HLA gene polymorphisms have been shown to be associated with the risk of graft-versus-host disease (GVHD) and outcome of allogeneic haematopoietic stem cell transplantation (AHSCT). This study aims to investigate the role of IL6, TNFα, IL10, IL2 and IL12 gene polymorphisms in the outcome of AHSCT in a South East Asian population. A total of 67 patients and 59 donors who underwent HLA-identical matched sibling AHSCT were available for analysis. There was no significant association between the different cytokine genotypes of patients with the incidence and severity of acute GVHD. Patients with IL2 166∗T allele and patients who received donor stem cells who had IL2 166∗G allele appeared to have reduced incidence of cGVHD. Patients who received donor stem cells with IL12 1188∗C allele are found to be associated with better disease free survival. These results suggest a possible role of IL2 and IL12 gene polymorphisms in the outcome of AHSCT in a South East Asian population.

Complementary and alternative medicine use in patients with hematological cancers in Malaysia.

BACKGROUND: Complementary and alternative medicine (CAM) is often used by cancer patients, but not many studies had been published on the prevalence of CAM use in patients with hematological cancers. This study aims to determine the prevalence of CAM and type of CAM used in this group of patients in a multiracial and multicultural country. PATIENTS AND METHODS: This is a cross-sectional survey carried out in two hospitals in Malaysia. Patients with underlying hematological cancers were asked to complete the questionnaires on CAM and the Hospital Anxiety and Depression Scale. RESULTS: A total of 245 patients participated. The prevalence of CAM use was 70.2 %. The most common types of CAM used are biological-based therapies (90.2 %) and mind-body interventions (42 %). Vitamin and diet supplements (68.6 %) and folk/herb remedies (58 %) are the most common biological-based therapies used. There is no significant association of CAM use with age, gender, education level, and household income. Female patients are more likely to use more than one CAM therapies. The most common reason reported for CAM use was to boost immunity (57 %) and cure (24 %). Majority of patients (65 %) felt CAM was effective, and 60 % did not inform their physicians regarding CAM usage. CONCLUSION: In view of the high prevalence of CAM use in patients with hematological cancers, it is important that the physicians play an active role in seeking information from patients and to monitor possible drug-vitamin-herbal interactions.
