    INTRODUCTION: Analysis of epidemiological as well as survival differences among the multiethnic population of Malaysia with prostate cancer is important.

    METHODS: Patients confirmed by transrectal-ultrasonographic-guided-biopsy performed from 2002 to 2008 were enrolled and analysed according to ethnicity, age, PSA level, Gleason score, stage of disease and survival.

    RESULTS: Among 83 patients, there were 38 Malay, 40 Chinese, 3 Indians and 2 others. Median age at diagnosis was 69.9 (range: 59-93), 43 patients (51.8%) being diagnosed before the age of 70. The median PSA level upon diagnosis was 574 ng/ml (range: 1-8632) and the median Gleason score was 7 (range: 2-10). Over half were already in Stage 4 when diagnosed. The most common site of metastasis was the bone. As a result the commonest prescribed treatment was hormonal manipulation. Five patients underwent radical prostatectomy and a further thirteen patients had radical radiotherapy (stage I: 1 patient, stage II: 7 patients and stage III: 5 patients). Ten patients defaulted follow-up. The median disease-specific survival was 21.9 months (range: 1-53).

    CONCLUSIONS: Prostatic carcinoma is a disease of the elderly and it is frequently diagnosed late in Malaysia. Greater efforts should be made to educate Malaysians regarding prostate cancer.

    OBJECTIVE: Research over the past several decades has indicated that low socioeconomic class has a direct effect on health outcomes. In Malaysia, class distribution may differ with the region. The objective of this study was to compare the presentation and survival of colorectal cancer patients in two dissimilar cities, Kuala Lumpur and Kuching, Sarawak.

    METHODS: All patients diagnosed with a malignancy of the colon or rectum in Sarawak General Hospital and University of Malaya Medical Center from 1st Jan 2000-31st Dec 2006 were recruited. Data on presentation, socio-economic class and survival were obtained. The survival duration was categorized into more than three years or three years and less. Testing for significance was performed using the chi-square test, with p values less than 0.05 considered statistically significant.

    RESULTS: A total of 565 patients in UMMC and 642 patients in SGH had a new diagnosis of colorectal carcinoma. Patients in Kuching had a longer duration of symptoms and more advanced stage at presentation, but this was not statistically significant. Lower socio-economic class was a significant factor for late and more advanced stage at diagnosis, as well as poorer three and five year survival rates. However, survival was lower for patients in Kuching compared to Kuala Lumpur, even after matching for socio-economic class.

    CONCLUSION: There is near-zero awareness of colorectal cancer screening in Malaysia. These findings support reaching out to communities of lower socioeconomic backgrounds to improve the colorectal cancer survival rates.

    BACKGROUND: Extraskeletal (soft tissue) chondromas are rare neoplasms. They are seen most frequently in the soft tissues of hands and feet. A chondroma occurring in the breast is exceedingly uncommon. We present a case of pure chondroma of the breast in a young woman in whom fine needle aspiration (FNA) cytologic features suggested a cartilaginous neoplasm.

    CASE: A 28-year-old woman presented with a mobile lump in the left breast. Mammography showed a high-density nodule without microcalcifications. A clinical diagnosis of fibroadenoma was made. A differential diagnosis was obtained on FNA. Excisional biopsy of the lump showed the histopathologic features of chondroma. There was no recurrence or appearance of new lesion during 13 months of follow-up.

    CONCLUSION: Chondroma of the breast shows FNA cytologic features of cartilaginous tumor, but specific tumor typing may not be possible. This case highlights the difficulties that may arise in FNA diagnosis of cartilaginous tumor especially when it occurs at an unusual site. Awareness of the cytologic features combined with clinical and radiologic findings should guide the cytopathologist to make correct diagnosis of this neoplasm.

    Ovarian cancer is today the most lethal female cancer with an overall survival of only 49.9%. The currently available screening modalities are disappointing in detecting highly curable early stage ovarian cancer. Natural history of ovarian cancer is unknown; it appears it can develop quickly from normal looking ovaries. Timely referral of women with non-specific symptoms (such as abdominal bloating, pelvic pain) for an ultrasound scan or blood CA125 assessments may help in the early diagnosis. Patients with Stage IA or IB disease with grade 1 tumors have a cure rate of >90%; this is likely to be compromised by laparoscopic surgery. In selected patients fertility preservation with good obstetric outcome is possible. However, the relapse rate in 'high risk' early stage ovarian cancers is 40-45%; adjuvant chemotherapy is needed. Only 20-25% of those with stage III and IV disease are cured. Despite a high primary response (70%) majority (70-75%) will relapse and all are likely to succumb. Optimal debulking surgery followed by adjuvant chemotherapy are needed for stages III and IV disease; the outcome is superior if managed by gynecologic oncologists. Where cost of drugs is an important consideration, an alternative is carboplatin (an affordable and equally effective drug). The role of vaccines needs further study. When relapses occur palliation will be the aim in most instances. Oral contraceptives, breast feeding, tubal sterilization and hysterectomy also have a protective effect. Risk-reducing salpingo-oopherectomy has been suggested in women with BRCA mutations.

    It is well established that almost all colorectal cancers arise from benign, neoplastic adenomatous polyps. In previous studies, intake of fruits, vegetables and legumes were found to decrease the risk for colorectal adenomas (CRA) and colorectal cancer. This case-control study aimed to evaluate the roles of a variety of foods in contributing to the risk of CRA in Malaysian subjects. One hundred and eighteen subjects were recruited into case (n=59) and control (n=59) groups at Hospital Kuala Lumpur (HKL). A pre-tested quantitative food frequency questionnaire (FFQ) was used to record the types of food items and frequency consumed. Logistic regression was used to determine the crude and adjusted odds ratios of the independent variables. Soy bean and soy products were associated with a reduced risk for CRA (OR = 0.38, 95% CI = 0.15-0.98), while tubers were associated with increase in risk four-fold (OR = 4.14, 95% CI = 1.60-10.70) and red meat intake was found to increase the risk two and a half-fold (OR = 2.51, 95% CI = 1.02-6.28). Higher servings of fruits and vegetables were found to significantly decrease the risk (OR fruits = 0.47, 95% CI = 0.30-0.74; OR vegetables = 0.49, 95% = 0.29-0.80). In conclusion, our data support protective roles for soy, fruits and vegetables in the aetiology of colorectal adenomas and increase in risk in those with high intakes of red meat and tubers. Food intake of an individual may have an influence on one's risk for developing CRA. This finding warrants further investigation before the protective effect of these food items is to be accepted. New studies should explore the possibility of these associations among individuals in the general population especially with regard to different ethnic or other groups in Malaysia with low fruit and vegetable consumption.

    BACKGROUND: Breast cancer is the commonest cancer amongst Malaysian women but local survival data are scarce. The present study was therefore conducted to assess overall survival and prognostic factors in Malaysian breast cancer patients.

    METHODS: The research sample was a prospective cohort of 413 patients diagnosed with breast cancer in the University of Malaya Medical Centre between 1993 to 1997. Survival data were obtained from the National Registry of Birth and Deaths in December 2000. The clinico-pathological variables studied were age, ethnic group, stage, tumour size, lymph node status, oestrogen receptor status and grade. The data were analysed utilizing Splus statistical software. The important prognostic factors were identified by fitting the Cox's proportional hazard model to the data set. Survival probabilities were estimated using the Kaplan-Meier method and differences were compared by the log-rank test.

    RESULTS: The overall 5-year survival was 59.1%. The Cox's proportional hazard model identified stage, lymph node status, size and grade as factors that correlated with prognosis. Age was not a significant prognostic factor. The Cox regression model by stepwise selection showed stage, nodal status and grade of tumour to be independent prognostic factors, whereas ethnicity, age and ER status were not.

    INTERPRETATION: The overall survival in our centre was low. Recognizing factors that affect prognosis of breast cancer patients in Malaysia may improve delivery of health care to at-risk groups by strategizing interventions as survival depends on early detection and effective treatment.

    OBJECTIVE: To determine the trend of cancer cases in one major hospital in Kelantan over a 20 year period from 1987 to 2007 and to speculate the change in trend due to the socio-economic and other health status in the state.

    METHODOLOGY: All data on clinically diagnosed cancer cases in Hospital Universiti Sains Malaysia [HUSM] were retrieved from the hospital medical records. The cancers were classified according to ICD10 and scrutinized to avoid duplicate or more entries. The increment in cancer incidence was calculated based on total numbers of cancer cases per each 5-6 year period.

    RESULTS: A total of 12,228 solid cancers were diagnosed during the period. There is an increment of 20.1% for 1991-1996 from 1987-1990 period, 67.4% for 1997-2001 from 1991-1996 period and 305.9% for 2002-2007 from the 1997-2001 period. The rise was steep in the last 5-6 years. After excluding referred cases from states outside Kelantan, the increments were 20.1%, 67.4% and 143.6% for the consecutive 5-6 year periods. The predominant rising trends were seen for cancers of the female organs, digestive tract and endocrine organs.

    CONCLUSION: Cancer cases in HUSM are showing a rising trend, associated with increasing prevalence of smoking, obesity and diabetes in the community served by the hospital. Since HUSM is the only hospital managing cancer in the state of Kelantan, to reduce cancer incidence in the state, life-style issues need to be addressed.

    The Malaysian National Renal Registry was set up in 1992 to collect data for patients on renal replacement therapy (RRT). We present here the report of the Malaysian dialysis registry. The objectives of this papar are: (1) To examine the overall provision of dialysis treatment in Malaysia and its trend from 1980 to 2006. (2) To assess the treatment rate according to the states in the country. (3) To describe the method, location and funding of dialysis. (4) To characterise the patients accepted for dialysis treatment. (5) To analyze the outcomes of the dialysis treatment. Data on patients receiving dialysis treatment were collected at initiation of dialysis, at the time of any significant outcome, as well as yearly. The number of dialysis patients increased from 59 in 1980 to almost 15,000 in 2006. The dialysis acceptance rate increased from 3 per million population in 1980 to 116 per million population in 2006, and the prevalence rate from 4 to 550 per million population over the same period. The economically advantaged states of Malaysia had much higher dialysis treatment rates compared to the less economically advanced states. Eighty to 90% of new dialysis patients were accepted into centre haemodialysis (HD), and the rest into the chronic ambulatory peritoneal dialysis (CAPD) programme. The government provided about half of the funding for dialysis treatment. Patients older than 55 years accounted for the largest proportion of new patients on dialysis since the 1990s. Diabetes mellitus has been the main cause of ESRD and accounted for more than 50% of new ESRD since 2002. Annual death rate averaged about 10% on HD and 15% on CAPD. The unadjusted 5-year patient survival on both HD and CAPD was about 80%. Fifty percent of dialysis patients reported very good median QoL index score. About 70% of dialysis patients were about to work full or part time. There has been a very rapid growth of dialysis provision in Malaysia particularly in the older age groups. ESRD caused by diabetes mellitus, despite being a preventable and treatable cause of ESRD--has increased and accounted for more than 50% of incident dialysis patients. Death and survival rates on dialysis are comparable to those from other countries.

    Photodynamic therapy (PDT) is a promising cancer treatment which involves activation of a photosensitizing drug with light to produce reactive oxygen species that kill tumors without causing damage to unirradiated normal tissues. To date, only Photofrin, Foscan and Levulan have been approved for clinical treatment of cancer. Tropical habitats such as those found in Malaysia are attractive sources of new therapeutic compounds as tremendous chemical diversity is found in a large number of plants, animals, marine- and micro-organisms. In our screening program for novel photosensitizers from nature, colorful strains of fungi (from Aspergillus and Penicillium genus) and bacteria (including actinomycetes and photosynthetic bacteria) were collected from various habitats in Peninsular Malaysia, such as coastal soil, peat soil, marine sponges and wastewater ponds. Methanolic extracts from a total of 85 different species were evaluated with a short-term cell viability assay for photo-cytotoxicity, where a promyelocytic leukemia cell-line, HL60 incubated with 20 microg/ml of extracts was irradiated with 9.6 J/cm(2) of a broad spectrum light. Two of these extracts, one from Rhodobacter sphaeroides (PBUM003) and one from Rhodopseudomonas palustris (PBUM001) showed moderate to strong photo-cytotoxicity. Subsequent bioassay guided isolation of the PBUM001 extract yielded known photosensitisers that are based on bacteriochlorophyll-a by comparing their molecular weight data, HPLC profiles and UV-vis absorption spectra with literature values, thereby demonstrating the validity of our screening approach.

    Survival after diagnosis of cancer is one of the major outcome measurements and a key criterion for assessing quality of cancer control related to both the preventive and the therapeutic level. The purpose of this study was to determine the 8-year survival time in Malaysia based on socio-demographic and clinical characteristics. A retrospective study of 472 Malaysian women with breast cancer from the Medical Record Department at University Kebangsaan Malaysia Medical Centre (UKMMC) was therefore performed with survival analysis carried out using the Kaplan-Meier with log-rank test for univariate analysis and Cox-regression for multivariate analysis. Women who had cancer or family history of cancer had a longer 8-year survival time (p = 0.008) compared with others who did not have such a history. Tamoxifen use, positive oestrogen receptor status, and race were prognostic indicators for 8-year survival time (p = 0.036, p = 0.018, p = 0.053, respectively) in univariate analysis. Multivariate analysis showed that being Malays and having no family history of cancer were independent prognostic factors for shorter survival time (p = 0.008, p = 0.012, respectively). In conclusion, being Chinese and having a family history of cancer are predictors of longer survival among the Malaysian breast cancer women.

    In the last decade, chemotherapy in combination with focal therapy (chemoreduction) has been increasingly used in intraocular retinoblastoma to avoid enucleation and radiotherapy. The aim of this study was to assess the feasibility and outcome of chemoreduction in Malaysian children with retinoblastoma. This was a prospective study from August 2001 to January 2006. Twenty children (25 eyes) were given 4 cycles of chemoreduction, after which the response was assessed. Fourteen eyes showed a complete response, 10 eyes showed a partial response, and 1 eye had progressive disease. Twelve eyes developed progressive disease later, 9 after an initial complete response and 3 after a partial response. Overall, progressive disease occurred in 52%. There were 2 treatment failures, in Reese-Elsworth groups 3 and 4. Both eyes required enucleation. One eye in group 5 required second line chemotherapy to achieve a complete response. No eyes were irradiated. Five children (25%) defaulted follow-up, one of whom returned with disseminated disease. In conclusion, 4 cycles of chemoreduction achieved a durable complete response in only 12% of eyes. Chemoreduction is feasible in Malaysia but requires good patient compliance and close follow-up.

    Tetanus is still widely prevalent in many parts of the world especially in the developing countries. This study was conducted to assess the demographic and clinical features, treatment and outcome of tetanus in adults with a special emphasis on identification of predictors of mortality. This was a retrospective study of all adult patients admitted with tetanus over a three-year period from 1998 to 2000 at Lok Nayak Hospital, New Delhi, India. The demography, clinical features, treatment and complications of the patients were assessed and were evaluated against two possible outcomes- survival or death, to identify the predictors of mortality. There were 217 adults (148 males, 69 females) admitted with generalized tetanus during the study period. The mean age of the patients was 36.08 +/- 18.84 years. In most instances (63.5%), wounds / injuries served as the source of infection. Overall 31.8% had mild, 21.7% had moderate and 46.5% had severe disease at presentation. Respiratory failure and dysautonomia were the frequently observed complications. Of the 217 patients, 82 died - a mortality rate of 37.78%. Parameters that were significantly associated with increased mortality were: age (especially > 60 years); shorter duration of symptoms - trismus, rigidity and dysphagia; severe disease at presentation and shorter period of onset. Tetanus is a preventable disease associated with a high fatality rate. Universal coverage of immunization programme and appropriate wound prophylaxis is the corner stone of tetanus eradication. The treatment of tetanus is difficult and requires specialized and intensive care. The presence of parameters indicating an adverse outcome at the beginning in the patients will help identify the subset of patients that need more intensive management especially in resource poor nations.

    Microgravity, hypergravity, vibration, ionizing radiation and temperature fluctuations are major factors of outer space flight affecting human organs and tissues. There are several reports on the effect of space flight on different human cell types of mesenchymal origin while information regarding changes to vascular endothelial cells is scarce. Ultrastructural and cytophysiological features of macrovascular endothelial cells in outer space flight and their persistence during subsequent culturing were demonstrated in the present investigation. At the end of the space flight, endothelial cells displayed profound changes indicating cytoskeletal lesions and increased cell membrane permeability. Readapted cells of subsequent passages exhibited persisting cytoskeletal changes, decreased metabolism and cell growth indicating cellular senescence.

    Melanoma is a lethal skin cancer that occurs predominantly among Caucasians. In Malaysia, the incidence of melanoma is low. This is a retrospective study of clinical and histopathological features of patients with cutaneous melanoma who were seen at the University Malaya Medical Centre from 1998 to 2008. Thirty-two patients with cutaneous melanoma were recorded during that period. Of these, 24 had sought treatment at the onset of disease at our centre. Chinese patients constituted the largest group (19 cases). The median age of these 24 patients at the time of presentation was 62 years. 16 patients had melanoma involving the lower limb with 12 affecting the sole of the foot. None had melanoma arising from the face. Histopathology showed nodular melanoma in 22 cases (91.6%), with superficial spreading and acral lentiginous melanoma diagnosed in 1 case each. The majority of patients (62.5%) were found to be in Stage III of the disease at the time of diagnosis.

    Cell-based therapy has great potential to treat patients with lung diseases. The administration of cells into an injured lung is one method of repairing and replacing lost lung tissue. However, different types of delivery have been studied and compared, and none of the techniques resulted in engraftment of a high number of cells into the targeted organ. In this in vitro study, a novel method of cell delivery was introduced to investigate the possibility of delivering aerosolized skin-derived fibroblasts.
