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).

METHODS: We performed systematic searches using electronic databases including PubMed and EMBASE until December 2012. Key words included "metformin" AND ("ovarian cancer" OR "ovary tumor"). All human studies assessing the effects of metformin on ovarian cancer were eligible for inclusion. All articles were reviewed independently by 2 authors with a standardized approach for the purpose of study, study design, patient characteristics, exposure, and outcomes. The data were pooled using a random-effects model.

RESULTS: Of 190 studies retrieved, only 3 observational studies and 1 report of 2 randomized controlled trials were included. Among those studies, 2 reported the effects of metformin on survival outcomes of ovarian cancer, whereas the other 2 reported the effects of metformin on ovarian cancer prevention. The findings of studies reporting the effects on survival outcomes indicated that metformin may prolong overall, disease-specific, and progression-free survival in ovarian cancer patients. The results of studies reporting the effects of metformin on ovarian cancer prevention were meta-analyzed. It indicated that metformin tended to decrease occurrence of ovarian cancer among diabetic patients with the pooled odds ratio of 0.57 (95% confidence interval, 0.16-1.99).

MATERIALS AND METHODS: Electronic databases were systematically searched for randomized controlled trials incorporated as lifestyle activity through MEDLINE with the associated terms "physical activity or exercise", "quality of life" and "cancer survivor or people with cancer", 'lifestyle' and 'randomised controlled trial'. The period of search was confined to publication within January 2008 till December 2012 and further limits were to full text, peer reviewed, abstract available and English language.

RESULTS: Based on inclusion criteria, 45 articles were retrieved. Of these, 41 were excluded after examining the full paper. Four final articles on randomized controlled trials were studied to determine the effectiveness of PA to improve the quality of life in post treatment cancer survivors and positive associations were found.

METHODS: One hundred and twenty cervical cancer patients diagnosed between 1st July 1995 and 30th June 2007 were identified. Data were obtained from medical records. The survival probability was determined using the Kaplan-Meier method and the log-rank test was applied to compare the survival distribution between groups.

RESULTS: The overall five-year survival was 39.7% [95%CI (Confidence Interval): 30.7, 51.3] with a median survival time of 40.8 (95%CI: 34.0, 62.0) months. The log-rank test showed that there were survival differences between the groups for the following variables: stage at diagnosis (p=0.005); and primary treatment (p=0.0242). Patients who were diagnosed at the latest stage (III-IV) were found to have the lowest survival, 18.4% (95%CI: 6.75, 50.1), compared to stage I and II where the five-year survival was 54.7% (95%CI: 38.7, 77.2) and 40.8% (95%CI: 27.7, 60.3), respectively. The five-year survival was higher in patients who received surgery [52.6% (95%CI: 37.5, 73.6)] as a primary treatment compared to the non-surgical group [33.3% (95%CI: 22.9, 48.4)].

METHODS: Two prospective groups of 423 and 965 newly diagnosed breast cancer patients in University of Malaya Medical Centre, Kuala Lumpur, Malaysia diagnosed in two time periods ie. 1993 to 1997 and in 1998 to 2002 were studied. Vital status was obtained from the National Registry of Births and Deaths. The overall survival was calculated from the date of diagnosis to the date of death from any cause. The survival differences between the two groups were analysed using the log-rank or Peto-Wilcoxon method. Survival estimates and independent prognostic factors were estimated by the Kaplan-Meier method and multivariate analysis using Cox proportional hazard models. P values less than 0.05 were considered statistically significant. Analyses were performed using SPlus 2000 Professional Release 2.

RESULTS AND DISCUSSION: Median follow-up for the two groups were 55 months (SD 29.2 months) in the first group and 52 months (SD 24.43) in the second group. There was improvement in 5-year observed survival from 58.4% (CI 0.54-0.63) to 75.7% (CI 0.73-0.79). The improvement in survival was significantly seen in all co-variates (p< 0.05) except for those aged 40 years and below (p= 0.27), tumour size 2 to 5 cm (p=0.11), grade 3 (p=0.32) and patients with Stage IV disease (p= 0.80). Stage of disease, lymph node (LN) involvement, size and grade were identified as independent prognostic factors in cohort one. For the second cohort; stage and LN involvement remained independent factors with the addition of ER status and ethnicity.

MATERIALS AND METHODS: This retrospective study examined breast cancer patients between 1st January 1994 and 31st December 2004 in UMMC. Survival analysis was performed using the Kaplan-Meier method and comparisons between groups using the log-rank test. Univariate and multivariate analysis on prognostic factors were carried out using the Cox's proportionate hazard model for patient demographics, and tumour and treatment factors.

RESULTS: One hundred and thirty six patients were identified, with a median age at diagnosis of 75 years. Most had at least one co-morbidity (61.8%). Only 75.0% had a good performance status (ECOG 0-1). Mean tumour size was 4.4 cm. Primary tumour stages (T stages) 3 and 4 were present in 8.1% and 30.1% of patients respectively, and 30.9% had stage III and 8.8% had stage IV disease based on overall AJCC staging. ER positivity was 58.1%. PR status was positive in 30.1%. Surgery was performed in 69.1% of the patients and mastectomy and axillary clearance were the commonest surgical procedures (50.7%). Some 79.4% of patients received hormonal therapy, 30.1% radiotherapy and only 3.6% chemotherapy. Non-standard treatment was given to 39.0% of patients due to a variety of reasons. The cumulative 5 years overall, relapse free and cause specific survivals were 51.9%, 79.7% and 73.3% respectively. Performance status, T3-4 tumour, presence of metastasis, tumour grade and ER status were independent prognostic factors for overall survival. For cause specific survival they were T4 tumour, presence of metastasis and ER status.

METHODS: The medical records of 118 Malay patients with oral cancer admitted in HUSM from 1st January 1986 to 31st December 2005 were reviewed. Data collected include socio-demographic background, high-risk habits practiced, clinical and histological characteristics, and treatment profile of the patients. Survival status and duration were determined by active validation until 31st December 2006. Data entry and analysis were accomplished using SPSS version 12.0. The Kaplan-Meier method was used to perform survival estimates while the log-rank test and the Cox proportional hazards regression model were employed to perform univariate analysis and multivariable analysis of the variables, respectively.

RESULTS: The overall five-year survival rate of Malay patients with oral cancer was 18.0%, with a median survival time of 9 months. Significant factors that influenced survival of the patients were age, sex, tumour site, TNM stage, histological type, and treatment received.
