    BACKGROUND: Nasopharyngeal carcinoma (NPC) is the commonest radiocurable cancer in Malaysia. This study aimed to determine the treatment outcomes and late effects of radiotherapy for NPC patients treated in University Malaya Medical Centre (UMMC).

    MATERIALS AND METHODS: All newly diagnosed patients with NPC referred for treatment to the Oncology unit at UMMC from 2004-2008 were retrospectively analyzed. Treatment outcomes were 5 years overall survival (OS), disease free survival (DFS), cause-specific survival (CSS), loco- regional control (LRC) and radiotherapy-related late effects. The Kaplan-Meier method was used for survival analysis and differences in survival according to AJCC stage was compared using the log-rank test.

    RESULTS: A total of 176 patients with newly diagnosed NPC were treated in UMMC during this period. Late presentation was common, with 33.5% presenting with T3-4 disease, 84.7% with N1-3 disease and 75.6% with AJCC stage 3-4 disease. Radical RT was given to 162 patients with 22.7% having RT alone and 69.3% having CCRT. The stipulated OTT was 7 weeks and 72.2% managed to complete their RT within this time period. Neoadjuvant chemotherapy was given to 14.8% while adjuvant chemotherapy was administered to 16.5%. The 5 years OS was 51.6% with a median follow up of 58 months. The 5 years OS according to stage were 81.8% for stage I, 77.9% for stage II, 47.4% for stage III and 25.9% for stage IV. The 5 years overall CSS, DFS and LRC were 54.4%, 48.4% and 70.6%, respectively. RT related late effects were documented in 80.2%. The commonest was xerostomia (66.7%). Other documented late effects were hearing deficit (17.3%), visual deficit (3.1%), neck stiffness (3.1%) , dysphagia (3.4%), cranial nerve palsy (2.5%), pneumonitis (0.6%) and hypothyroidism (1.2%).

    CONCLUSIONS: The 5 years OS and LRC in this study are low compared to the latest studies especially those utilizing IMRT. Implementation of IMRT for NPC treatment should be strongly encouraged.

    BACKGROUND: Head and neck cancer (HNC) is the eighth most common cancer as estimated from worldwide data. The incidence of HNC in Peninsular Malaysia was reported as 8.5 per 100,000 population. This study was aimed to determine the treatment outcomes for HNC patients treated in the Oncology Unit of University Malaya Medical Centre (UMMC).

    MATERIALS AND METHODS: All newly diagnosed patients with squamous cell carcinoma of head and neck (HNSCC) referred for treatment to the Oncology Unit at UMMC from 2003-2010 were retrospectively analyzed. Treatment outcomes were 5-year overall survival (OS), cause specific survival (CSS), loco-regional control (LRC) and radiotherapy (RT) related side effects. Kaplan-Meier and log rank analyses were used to determine survival outcomes, stratified according to American Joint Committee on Cancer (AJCC) stage.

    RESULTS: A total of 130 cases were analysed. Most cases (81.5%) were at late stage (AJCC III-IVB) at presentation. The 5-year OS for the whole study population was 34.4% with a median follow up of 24 months. The 5-year OS according to AJCC stage was 100%, 48.2%, 41.4% and 22.0% for stage I, II, III and IVA-B, respectively. The 5-year overall CSS and LCR were 45.4% and 55.4%, respectively. Late effects of RT were documented in 41.4% of patients. The most common late effect was xerostomia.

    CONCLUSIONS: The treatment outcome of HNSCC at our centre is lagging behind those of developed nations. Efforts to increase the number of patients presenting in earlier stages, increase in the use of combined modality treatment, especially concurrent chemoradiotherapy and implementation of intensity modulated radiotherapy, may lead to better outcomes for our HNC patients.

    BACKGROUND: Locally advanced breast cancer (LABC) is characterized by the presence of a large primary tumour (>5 cm) associated with or without skin or chest-wall involvement (T4) or with fixed (matted) axillary lymph nodes in the absence of any evidence of distant metastases. These cancers are classified as stage IIIA and IIIB according to the AJCC Staging System. Treatment of choice involves combinations of surgery, chemotherapy, radiotherapy and/or hormonal therapy. Current guidelines recommend primary surgery or neoadjuvant therapy followed by surgery. The primary objective of this study was to compare the outcome of LABC patients subjected to neoadjuvant chemotherapy before surgery and those who underwent surgery as the primary treatment and to determine prognostic predictors. Secondary objectives were to evaluate the response after neoadjuvant therapy and to determine the treatment compliance rate.

    METHODS: This retrospective study of Stage III breast cancer patients was conducted over a 5 year period from 1998 to 2002. The survival data were obtained from the National Registry of Births and Deaths with the end-point of the study in April 2006. The Kaplan Meier method was applied for survival analysis. Cox regression analysis by stepwise selection was performed to identify important prognostic factors.

    RESULTS: Out of a 155 evaluable patients, 74 (47.7%) had primary surgery, 62 (40%) had neoadjuvant chemotherapy, 10 patients (6.5%) were given Tamoxifen as the primary treatment, while 9 patients (5.8%) defaulted any form of treatment. After neoadjuvant chemotherapy, 9 patients defaulted further treatment, leaving 53 evaluable patients. Out of these 53 evaluable patients, 5 patients (9.4%) had complete pathological response, 5 (9.4%) a complete clinical response, and 26 (49.1%) had partial response after neoadjuvant chemotherapy. The 5-year survival in the primary surgery group was 56.7 % compared to 44.7% in the neoadjuvant chemotherapy group (p<0.01). The important prognostic factors were race, size of tumour, nodal status, estrogen receptor status and response to neoadjuvant chemotherapy.

    CONCLUSION: Patients who had primary surgery had better survival than those who underwent neoadjuvant chemotherapy, which may be due to bias in the selection of patients for neoadjuvant chemotherapy. Out of a total of 155 patients, 25.1% defaulted part of the treatment, or did not receive optimal treatment, emphasizing the importance of psychosocial support and counselling for this group of patients.

    Objective: This study aims to develop, validate and determine the reliability of an interactive multimedia strategy to prevent tobacco use among the young (TUPY-S) from an adolescents’ perspective. Methods: A descriptive study design was utilized. A modular instruction guideline by Russel (1974) was followed in the entire process, comprising a feasibility study, a review of existing modules, specification of the objectives, identification of the construct criterion items, learner analysis and entry behavior specification, establishment of the sequence instruction and media selection, a tryout with students and a field test. Result: Feasibility was agreed among the researchers and the school authorities. Culturally suitable rigorously developed tobacco use preventive strategies delivered using information technology (IT) are lacking in the literature. The objective of TUPY-S is to prevent tobacco use among adolescents living in Malaysia. Identified construct criterion items include knowledge, attitude, intention to use, self-efficacy, and refusal skill. The target population was early adolescents belonging to generation-Z. Content was developed from the adolescents’ perspective and delivered using IT in Malay language. Content validity, assessed by six experts in the field and module development, was good at 86%. The students’ tryout showed satisfactory face validity subjectively and objectively (85.5%) and high alpha Cronbach reliability (0.91). Conclusion: TUPY-S was confirmed to suit early adolescents of the current generation living in Malaysia. It demonstrated good content validity among the experts, satisfactory face validity and reliability among the target population. TUPY-S is ready to be evaluated for its effectiveness among early adolescents.

    PURPOSE: This study aimed to determine the association between tobacco consumption (kretek) and betel quid chewing with oral cancer risk.

    MATERIALS AND METHODS: A total of 81 cases of oral cancers were matched with 162 controls in this hospital-based study. Information on sociodemographic characteristics and details of risk habits (duration, frequency and type of tobacco consumption and betel quid chewing) were collected. Association between smoking and betel quid chewing with oral cancer were analysed using conditional logistic regression.

    RESULTS: Slightly more than half of the cases (55.6%) were smokers where 88.9% of them smoked kretek. After adjusting for confounders, smokers have two fold increased risk, while the risk for kretek consumers and those smoking for more than 10 years was increased to almost three-fold. Prevalence of betel quid chewing among cases and controls was low (7.4% and 1.9% respectively). Chewing of at least one quid per day, and quid combination of betel leaf, areca nut, lime and tobacco conferred a 5-6 fold increased risk.

    CONCLUSIONS: Smoking is positively associated with oral cancer risk. A similar direct association was also seen among betel quid chewers.

    The tumour suppressor genes, p53 and pRb, are known to play important roles in neoplastic transformation. While molecular routes to the uncontrolled growth of hepatocytes, leading to primary liver cancer have generated considerable interest, the roles of p53 and pRb mutations in hepatocellular carcinoma (HCC) and hepatoblastoma (HB) remain to be clarified. We examined the immunohistochemical expression of p53 and pRb gene products in 26 HCC and 9 HB, sampled into tissue microarray blocks. 10 (38%) of 26 HCC showed > 10% tumour nuclear staining for p53 protein, 3 of these also being HbsAg positive. Conversely, none of 9 HB expressed nuclear p53 immunopositivity. Some 24 (92%) HCC and 8 (89%) HB showed loss of pRb nuclear expression. Two of the 26 HCC and one of the 9 HB showed >10% tumour nuclear staining for pRb protein. Our results suggest that p53 does not have an important role in the development of HB but may contribute in HCC. There is also loss of pRb expression in the majority of HCC and HB, supporting loss of pRb gene function in the hepatocarcinogenesis pathway. However, a comparison of the staining profiles of p53 and pRb proteins in HCC and HB did not reveal a consistent pattern to differentiate between the two types of tumours immunohistochemically. Hence the use of p53 and pRB protein expression has no contribution in the situation where there is a diagnostic difficulty in deciding between HCC and HB.

    INTRODUCTION: Breast cancer is the leading cancer in women today and the major challenge is late presentation then later contributes to poor outcome and high fatality rate. Mammography is effective in early detection of breast cancer and consequently significantly improves the breast cancer survival.

    MATERIALS AND METHODS: This cross-sectional study was used to study the knowledge and awareness towards mammogram amongst women aged 15 years old and above. A systemic random sampling was applied and information gathered through guided interview by using a structured questionnaire.

    RESULTS: Eighty-six respondents were recruited. The mean age of respondents was 40.5 years (SD: 15.51) and more than 80% had secondary and tertiary level of education. The percentage of respondents ever performed mammogram was 10.5% (95% CI: 4.0%-17.0%). The rate of correct answers was between 8.1% and 48.8%. Most of the respondents do not sure the answer (45.3%-61.6%) rather than wrongly answer (4.7%-43.0%). Only about 8% truly answer that mammogram should be done once in a life. There are 10.5% of women claimed that mammogram had no serious side effect and not a painful procedure. Nearly half of respondents (48.8%) correctly mentioned that Mammogram can detect breast cancer in early stage.

    CONCLUSION: Only a small percentage of women ever performed mammogram and there are seriously unaware and poor knowledge pertaining to mammography screening for breast cancer among women in sub urban area. A massive health education campaign through multiple methods and agencies are needed to enhance the knowledge and awareness on mammogram.

    The mammalian target of rapamycin (mTOR) kinase plays an important role in regulating cell growth and cell cycle progression in response to cellular signals. It is a key regulator of cell proliferation and many upstream activators and downstream effectors of mTOR are known to be deregulated in various types of cancers. Since the mTOR signalling pathway is commonly activated in human cancers, many researchers are actively developing inhibitors that target key components in the pathway and some of these drugs are already on the market. Numerous preclinical investigations have also suggested that some herbs and natural phytochemicals, such as curcumin, resveratrol, timosaponin III, gallic acid, diosgenin, pomegranate, epigallocatechin gallate (EGCC), genistein and 3,3'-diindolylmethane inhibit the mTOR pathway either directly or indirectly. Some of these natural compounds are also in the clinical trial stage. In this review, the potential anti-cancer and chemopreventive activities and the current status of clinical trials of these phytochemicals are discussed.

    The aim of this study was to assess why women delay in getting treatment (i.e. surgery) for breast cancer, as well as to explore on what type of issues are involved in such delay cases. Basic interpretative of qualitative methodology was applied to construct the reality of delay phenomena, and its interaction with social worlds. Six themes were identified: new conception of breast cancer treatment, psychological defenses, health support system, symtomatology experience, model and barriers. The delay issue in breast cancer requires attention as a multidimensional problem as this will facilitate more comprehensive and effective intervention to reduce delay.

    The ER-/PR+ breast tumor may be the result of a false ER negative result. The aim of this study was to investigate whether there is a difference in patient and tumor characteristics of the ER-/PR+ phenotype in an Asian setting. A total of 2629 breast cancer patients were categorized on the basis of their age, ethnicity, tumor hormonal receptor phenotype, grade and histological type. There were 1230 (46.8%) ER+/PR+, 306 (11.6%) ER+/PR-, 122 (4.6%) ER-/PR+ and 972 (37%) ER-/PR-. ER-/PR+ tumors were 2.5 times more likely to be younger than 50 years at diagnosis (OR: 2.52; 95% CI: 1.72-3.67). Compared to ER+/PR+ tumors, the ER-/ PR+ phenotype was twice more likely to be associated with grade 3 tumors (OR:2.02; 95%CI: 1.00-4.10). In contrast, compared to ER-/PR- tumors, the ER-/PR+ phenotype was 90% less likely to be associated with a grade 3 tumor (OR: 0.12; 95%CI:0.05-0.26), and more likely to have invasive lobular than invasive ductal histology (OR: 3.66; 95%CI: 1.47-9.11). These results show that the ER-/PR+ phenotype occurs in a younger age group and is associated with intermediate histopathological characteristics compared to ER+/PR+ and ER-/PR- tumors. This may imply that it is a distinct entity and not a technical artifact.

    BACKGROUND: The survival outcomes for women presenting with early breast cancer are influenced by treatment decisions. In Malaysia, survival outcome is generally poor due to late presentation. Of those who present early, many refuse treatment for complementary therapy.
    OBJECTIVE: This study aimed to explore the decision making experiences of women with early breast cancer.
    MATERIALS AND METHODS: A qualitative study using individual in-depth interviews was conducted to capture the decision making process of women with early breast cancer in Malaysia. We used purposive sampling to recruit women yet to undergo surgical treatment. A total of eight participants consented and were interviewed using a semi-structured interview guide. These women were recruited from a period of one week after they were informed of their diagnoses. A topic guide, based on the Ottawa decision support framework (ODSF), was used to facilitate the interviews, which were audio recorded, transcribed and analysed using a thematic approach.
    RESULTS: We identified four phases in the decision-making process of women with early breast cancer: discovery (pre-diagnosis); confirmatory ('receiving bad news'); deliberation; and decision (making a decision). These phases ranged from when women first discovered abnormalities in their breasts to them making final surgical treatment decisions. Information was vital in guiding these women. Support from family members, friends, healthcare professionals as well as survivors also has an influencing role. However, the final say on treatment decision was from themselves.
    CONCLUSIONS: The treatment decision for women with early breast cancer in Malaysia is a result of information they gather on their decision making journey. This journey starts with diagnosis. The women's spouses, friends, family members and healthcare professionals play different roles as information providers and supporters at different stages of treatment decisions. However, the final treatment decision is influenced mainly by women's own experiences, knowledge and understanding.

    Psychosocial and cultural factors influencing cancer health behaviour have not been systematically investigated outside the western culture, and qualitative research is the best approach for this type of social research. The research methods employed to study health problems in Asia predominantly are quantitative techniques. The set up of the first psychosocial cancer research network in Asia marks the beginning of a collaboration to promote and spearhead applied qualitative healthcare research in cancer in the UK, Southeast Asia and the Middle East. This paper sets out the rationale, objectives and mission for the UK-SEA-ME Psychosocial-Cultural Cancer Research Network. The UK-SEA-ME network is made up of collaborators from the University of Leeds (UK), the University of Malaya (Malaysia), the National University of Singapore (Singapore) and the University of United Arab Emirates (UAE). The network promotes applied qualitative research to investigate the psychosocial and cultural factors influencing delayed and late presentation and diagnosis for cancer (breast cancer) in partner countries, as well as advocating the use of the mixed-methods research approach. The network also offers knowledge transfer for capacity building within network universities. The mission of the network is to improve public awareness about the importance of early management and prevention of cancer through research in Asia.

    Background: Breast cancer (BC) awareness is relatively poor among Malaysian women indicated by the presence
    of BC at a late stage and the low rate of mammography screening. Only a few theoretically based studies have been
    conducted on Malaysian women’s participation in mammography. Therefore, the objective of this study is to use health
    belief model (HBM) and stage of change model (SCM) to determine the relationship between health beliefs on the
    behavioral adoption of mammography amongst women in Kuantan, Pahang. Methods: Five hundred and twenty women
    were randomly selected to complete the survey. Data were analyzed using multinomial logistic regression (MLR) to
    ascertain the multivariate relationships between health beliefs and stage of mammography behavioral adoption. Results:
    The MLR test indicates that there is no significant difference in perceived severity, benefits, motivator factors and cues
    to action between participants in the action stage and the maintenance stage. However, significant differences existed
    in perceived severity, susceptibility, motivator factors and self-efficacy between the pre-contemplation, relapse and
    contemplation stage to that of the referenced (maintenance) stage of mammography adoption. Conclusion: Women in
    the action stage are more likely to progress towards maintenance stage as they perceived breast cancer as a disease that
    leads to death and that mammogram screening is beneficial in detecting the disease at an early stage. However, women
    in the pre-contemplation, relapse and contemplation stage are found unlikely to move towards the maintenance stage
    as they perceived their risk of getting breast cancer is low.

    Objectives: The Center for Epidemiologic Studies Depression Scale (CES-D) was specifically created to assess
    depression in cancer patients. However, to date, the CES-D has not been validated in Farsi. Therefore, this study aimed to
    assess the psychometric properties of the CES-D in Iranian cancer patients. Methods: During a three-month period
    (October to December, 2015), a total of 380 cancer patients completed a Farsi version of the CES-D. The construct
    validity of the scale was evaluated by exploratory factor analysis. Reliability was assessed using Cronbach’s alpha
    and McDonald Omega. All of the statistical procedure were run by SPSS 22 (SPSS Inc., Chicago, IL, USA). Results:
    The construct validity of the CES-D determined three factors (somatic affect, negative affect, and positive affect),
    which explained 65.60% of the total variance. The internal consistency was greater than 0.70. Conclusion: Findings
    revealed that the Farsi version of the CES-D has acceptable validity and reliability, which can be used to measure
    depression in Iranian cancer patients.

    BACKGROUND: Qigong is highly favoured among Asian breast cancer survivors for enhancing health. This study examined the hypothesis that quality of life (QoL) in the Qigong group is better than the placebo (aerobic) or usual care group.

    MATERIALS AND METHODS: A total of 197 participants were randomly assigned to either the 8-week Kuala Lumpur Qigong Trial or control groups in 2010-2011. Measurement taken at baseline and post- intervention included QoL, distress and fatigue. Analysis of covariance (ANCOVA) and Kruskal Wallis were used to examine for differences between groups in the measurements.

    RESULTS: There were 95 consenting participants in this 8week trial. The adherence rates were 63% for Qigong and 65% for the placebo group. The Qigong group showed significant marginal improvement in Quality of life scores compared to placebo (mean difference=7.3 unit; p=0.036), compared to usual care (mean difference=6.7 unit; p=0.048) on Functional Assessment Cancer Therapy-Breast measure. There were no significant changes between the placebo and usual care groups in fatigue or distress at post intervention (8-week).

    CONCLUSIONS: Cancer survivors who participated in the Qigong intervention showed slightly better QOL. Follow up studies are greatly needed to evaluate which subgroups may best benefit from Qigong. With a steep rise of cancer survivors, there is an urgent need to explore and engage more cultural means of physical activity to fight side effects of treatment and for cancer control in developing countries.

    The role of The Transtheoretical Model (TTM) in predicting relapse is limited. We aimed to assess whether this model can be utilised to predict relapse during the action stage. The participants included 120 smokers who had abstained from smoking for at least 24 hours following two Malaysian universities' smoking cessation programme. The smokers who relapsed perceived significantly greater advantages related to smoking and increasing doubt in their ability to quit. In contrast, former smokers with greater self-liberation and determination to abstain were less likely to relapse. The findings suggest that TTM can be used to predict relapse among quitting smokers.

    OBJECTIVE: Poor health literacy is positively associated with poorer quality of health decision-making and health outcomes in women facing a cancer diagnosis. In developing countries, poor access to complete and accurate information continues to pose a challenge for women. This paper describes the knowledge of Malaysian women with regard to breast cancer and how participation in a self-management program can improve the situation.

    METHODS: Secondary analysis of data collected during a clinical trial on women newly diagnosed with breast cancer (n=147) was performed to examine baseline knowledge of breast cancer profile. Knowledge levels of women in the experimental (n= 69) group attending a self-management program were compared to a control group (n= 78) to determine change in the level of knowledge over time.

    RESULTS: At baseline, a high percentage of women were unaware of their breast cancer profile. Not a single woman had knowledge of all six basic characteristics; 83% did not know their HER2 status, type of breast cancer (68%), grade of cancer cell (64%), hormonal receptor status (55%), size of breast cancer (18%) and/or their stage of breast cancer (13%). At post intervention, there was significantly better knowledge within the experimental group.

    CONCLUSION: Malaysian women in this cohort study demonstrated very low levels of knowledge of their cancer profile. Clinical implications for countering treatment-decision difficulties include the need for a shift in the way information and services are delivered to allow women to take a more active role in their own care. Multi-modal efforts including basic information dissemination to increase women's knowledge can contribute to narrowing of the gap in health disparity.

    Objective: This study aimed at exploring the association of TP53 72Arg/Pro polymorphism and Risk of Chronic
    Lymphocytic Leukemia and to assess the correlation between TP53 72Arg/Pro polymorphism and clinical parameter,
    hematological profile and some biological prognostic markers among Sudanese patients with chronic lymphocytic
    leukemia. Methods: A case-control study was conducted in Khartoum state, Sudan, during the period from April 2017 to
    April 2018, involved 110 B-CLL patients and 80 healthy volunteers as a control group. Physical examination, Complete
    Blood Count and Immunophenotype were performed in all patients to confirm the diagnosis. Clinical staging such as
    Rai and Binet were studied. CD38 and ZAP70 were performed by Flow Cytometry. Blood samples were collected from
    all participants; DNA was extracted by using ANALYTIKJENA Blood DNA Extraction Kit (Germany) and analyzed
    TP53 codon 72Arg/Pro Polymorphism by using AS-PCR. The statistical analysis was performed using SPSS version
    23.0 software (Chicago, IL, USA). Results: the Arg/Pro was the most frequent genotype in B-CLL patients(50%),
    followed by Arg/Arg (25.5%) and Pro/Pro (24.5%), whereas in healthy control group Arg/Pro was the most frequent
    (47.5%), followed by Arg/Arg (45%) and Pro/Pro (7.5%). Our data indicate a higher frequency of homozygous Pro/
    Pro in the B-CLL patients as compared to controls with an OR of 4.01 for the Pro/Pro genotype and lower frequency
    of Arg/Arg genotype in CLL patients as compared to controls with an OR of .42 for the Arg/Arg genotype. Also, the
    Pro allele showed higher risk than Arg allele (P value=0.000, OR 2.23, 95% CI=1.45-3.41). No significant association
    between gender, clinical staging systems (Rai, Binet), biological prognostic markers (CD38 expression or ZAP70
    expression), and TP53 codon 72Arg/Pro polymorphisms, except Arg/Arg genotype tended to be associated with younger
    age (P =0.04). Conclusion: Our data suggested that Pro/Pro genotype contribute to increased susceptibility to B-Chronic
    Lymphocytic Leukemia risk in our population tenfold higher than those had Arg/Arg genotype.

    BACKGROUND: Waterpipe tobacco smoking has becoming popular especially among young people worldwide. Smokers are attracted by its sweeter, smoother smoke, social ambience and the misconception of reduced harm. The objective of this study was to systematically review the effects of waterpipe tobacco policies and practices in reducing its prevalence.

    MATERIALS AND METHODS: A systematic review was conducted electronically using the PubMed, OVID, Science Direct, Proquest and Embase databases. All possible studies from 1980 to 2013 were initially screened based on titles and abstracts. The selected articles were subjected to data extraction and quality rating.

    RESULTS: Three studies met the inclusion criteria and were eligible for this review. Almost all of the waterpipe tobacco products and its accessories did not comply with the regulations on health warning labelling practices as stipulated under Article 11 of WHO FCTC. In addition, the grisly new warning labels for cigarettes introduced by Food and Drug Administration did not affect hookah tobacco smoking generally. Indoor air quality in smoking lounges was found to be poor and some hookah lounges were operated without smoke shop certification.

    CONCLUSIONS: Our findings revealed the availability of minimal information on the practices in controlling waterpipe smoking in reducing its prevalence. The lack of comprehensive legislations or practices in controlling waterpipe smoking warrants further research and policy initiatives to curb this burgeoning global epidemic, especially among the vulnerable younger population.
