    Musculoskeletal tumour is much less common compared to tumours of epithelial origin. Most of these tumours are benign, with only about 1% malignant in nature. A general orthopaedic surgeon may only come across a malignant primary bone or soft tissue tumour a few times in his entire medical career. The current recommendation is for these conditions to be investigated and treated in centres with musculoskeletal oncology service. Careful clinical evaluation with appropriate plain radiography can provide adequate information for definitive diagnosis and treatment for most cases, especially the benign tumours. For some other cases, further investigations will be necessary. Magnetic resonance imaging (MRI) can provide excellent details on anatomical location of a tumour and delineate vital structures that may have been distorted by the lesion. For primary malignant tumours, computerized tomography scanning is still the gold standard for evaluation of pulmonary metastasis, and bone scan can allow early detection of distant metastasis to other bones. Whole body MRI has recently been recommended for tumour staging but the potential benefit for musculoskeletal tumour is not that convincing. PET may be very helpful for follow up detection of tumour recurrence but its role in diagnosis and staging of musculoskeletal tumours is still being evaluated...

    BACKGROUND: The three standard biomarkers used in breast cancer are the estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2). The Ki-67 index, a proliferative marker, has been shown to be associated with a poorer outcome, and despite absence of standardization of pathological assessment, is widely used for therapy decision making. We aim to study the role of the Ki-67 index in a group of Asian women with breast cancer.

    MATERIALS AND METHODS: A total of 450 women newly diagnosed with Stage 1 to 3 invasive breast cancer in a single centre from July 2013 to Dec 2014 were included in this study. Univariable and multivariable logistic regression was used to determine the association between Ki-67 (positive defined as 14% and above) and age, ethnicity, grade, mitotic index, ER, PR, HER2, lymph node status and size. All analyses were performed using SPSS Version 22.

    RESULTS: In univariable analysis, Ki -67 index was associated with younger age, higher grade, ER and PR negativity, HER2 positivity, high mitotic index and positive lymph nodes. However on multivariable analysis only tumour size, grade, PR and HER2 remained significant. Out of 102 stage 1 patients who had ER positive/PR positive/HER2 negative tumours and non-grade 3, only 5 (4.9%) had a positive Ki-67 index and may have been offered chemotherapy. However, it is interesting to note that none of these patients received chemotherapy.

    CONCLUSIONS: Information on Ki67 would have potentially changed management in an insignificant proportion of patients with stage 1 breast cancer.

    Stage of cervical cancer may adversely affect the quality of life (QOL) among patients. The objective of this study was to predict the QOL among cervical cancer patients by the stage of their cancer. A cross-sectional study from September 2012 until January 2013 was conducted among cervical cancer patients who completed treatment. All patients completed a interviewer-guided questionnaire comprising four sections: (A) socio- demographic data, (B) medical history, (C) QOL measured by general health status questionnaire (QLQ-30) and (D) cervical cancer specific module CX-24 (EORTC) was used to measured patient's functional, symptom scale and their global health status. Results showed that global health status, emotional functioning and pain score were higher in stage III cervical cancer patients while role functioning was higher in stage I cervical cancer patients. Patients with stage IV cancer have a lower mean score in global health status (adjusted b-22.0, 95 CI% -35.6, -8.49) and emotional functioning (adjusted b -22.5, 95 CI% -38.1, -6.69) while stage III had lower mean score in role functioning (adjusted b -14.3, 95 CI% -25.4, -3.21) but higher mean score in pain (adjusted b 22.1, 95 CI% 8.56, 35.7). In conclusion, stage III and IV cervical cancers mainly affect the QOL of cervical cancer patients. Focus should be given to these subgroups to help in improving the QOL.

    Background: Breast cancer is the most common malignant disease and the leading cause of cancer death among
    women globally. This study aimed to determine the median survival time and prognostic factors for breast cancer
    patients in a North-East State of Malaysia. Methods: This retrospective cohort study was conducted from January till
    April 2017 using secondary data obtained from the state’s cancer registry. All 549 cases of breast cancer diagnosed
    from 1st January 2007 until 31st December 2011 were selected and retrospectively followed-up until 31st December
    2016. Sociodemographic and clinical information was collected to determine prognostic factors. Results: The average
    (SD) age at diagnosis was 50.4 (11.2) years, the majority of patients having Malay ethnicity (85.8%) and a histology of
    ductal carcinoma (81.5%). Median survival times for those presenting at stages III and IV were 50.8 (95% CI: 25.34,
    76.19) and 6.9 (95% CI: 3.21, 10.61) months, respectively. Ethnicity (Adj. HR for Malay vs non-Malay ethnicity=2.52;
    95% CI: 1.54, 4.13; p<0.001), stage at presentation (Adj. HR for Stage III vs Stage I=2.31; 95% CI: 1.57, 3.39; p<0.001
    and Adj. HR for Stage IV vs Stage I=6.20; 95% CI: 4.45, 8.65; p<0.001), and history of surgical treatment (Adj. HR
    for patients with no surgical intervention=1.95; 95% CI: 1.52, 2.52; p<0.001) were observed to be the statistically
    significant prognostic factors associated with death caused by breast cancer. Conclusion: The median survival time
    among breast cancer patients in North-East State of Malaysia was short as compared to other studies. Primary and
    secondary prevention aimed at early diagnosis and surgical management of breast cancer, particularly among the Malay
    ethnic group, could improve treatment outcome.

    Purpose: The prevalence of invasive lobular carcinoma (ILC), the second most common type of breast cancer, accounts for 5%-15% of all invasive breast cancer cases. Its histological feature to spread in rows of single cell layers explains why it often fails to form a palpable lesion and the lack of sensitivity of mammography and ultrasound (US) to detect it. It also has a higher incidence of multifocal, multicentric, and contralateral disease when compared to the other histological subtypes. The clinicopathologic features and outcomes of Invasive Ductolobular Carcinoma (IDLC) are very similar to the ILC. The purpose of our study is to assess the importance of MRI in the preoperative management and staging of patients affected by ILC or IDLC.

    Materials and Methods: We identified women diagnosed with ILC or IDLC. We selected the patients who had preoperative breast MRI. For each patient we identified the areas of multifocal, multicentric, or contralateral disease not visible to standard exams and detected by preoperative MRI. We analyzed the potential correlation between additional cancer areas and histological cancer markers.

    Results: Of the 155 women who met our inclusion criteria, 93 (60%) had additional cancer areas detected by MRI. In 61 women, 39,4% of the overall population, the additional cancer areas were confirmed by US/tomosynthesis second look and biopsy. Presurgical MRI staging changed surgical management in the 37,4% of the patients. Only six patients of the overall population needed a reoperation after the initial surgery. No statistically significant correlation was found between MRI overestimation and the presence of histological peritumoral vascular/linfatic invasion. No statistically significant correlation was found between additional cancer areas and histological cancer markers.

    Conclusions: Our study suggests that MRI is an important tool in the preoperative management and staging of patients affected by lobular or ductolobular invasive carcinoma.

    For a long time lung cancer was associated with a fatalistic approach by healthcare professionals. In recent years, advances in imaging, improved diagnostic techniques and more effective treatment modalities are reasons for optimism. Accurate lung cancer staging is vitally important because treatment options and prognosis differ significantly by stage. The staging algorithm should include a contrast computed tomography (CT) of the chest and the upper abdomen including adrenals, positron emission tomography/CT for staging the mediastinum and to rule out extrathoracic metastasis in patients considered for surgical resection, endosonography-guided needle sampling procedure replacing mediastinoscopy for near complete mediastinal staging, and brain imaging as clinically indicated. Applicability of evidence-based guidelines for staging of lung cancer depends on the available expertise and level of resources and is directly impacted by financial issues. Considering the diversity of healthcare infrastructure and economic performance of Asian countries, optimal and cost-effective use of staging methods appropriate to the available resources is prudent. The pulmonologist plays a central role in the multidisciplinary approach to lung cancer diagnosis, staging and management. Regional respiratory societies such as the Asian Pacific Society of Respirology should work with national respiratory societies to strive for uniform standards of care. For developing countries, a minimum set of care standards should be formulated. Cost-effective delivery of optimal care for lung cancer patients, including staging within the various healthcare systems, should be encouraged and most importantly, tobacco control implementation should receive an absolute priority status in all countries in Asia.

    The detection rate of thyroid incidentalomas is increasing; in fact, as many as 2.3% of patients undergoing FDG PET-CT for other indications have been found to have thyroid incidentalomas. The risk of malignancy in these thyroid incidentalomas can be as high as 47%. The increased uptake and the focal uptake pattern of F-18 fluorodeoxyglucose (FDG) in the thyroid during positron emission tomography (PET)-computed tomography (CT), and the calcification of the thyroid incidentaloma, are associated with even higher risk of malignancy. We report a case of a lady undergoing FDG PET-CT for breast cancer staging but noted to have a calcified thyroid incidentaloma, which was proven to be follicular thyroid carcinoma.

    Since its recognition about 150 years ago, there has been much progress in the understanding of the pathogenesis, prevention, early detection and management of carcinoma of the uterine cervix. Important historical landmarks include the (1) recognition of pre-invasive and pre-clinical lesions, and the devise of various systems for reporting these lesions, (2) improvements in diagnostic techniques particularly colposcopy, (3) advent of therapeutic procedures (electrocoagulation, cryotherapy, laser therapy and loop electrosurgical excision), and (4) recognition of the aetiological relationship between the human papillomavirus and cervical neoplasia. The susceptibility of the cervical transformation zone to malignant change is now well recognised. The WHO classification system remains the one most commonly utilised for histological reporting of cervical cancers. In the recent 1994 update, cervical carcinoma is divided into 3 main categories: squamous cell carcinoma, adenocarcinoma and other epithelial tumours. Squamous cell carcinoma (60-80%) predominates among invasive cervical carcinoma. Recognised variants include verrucous, warty (condylomatous), papillary squamous (transitional) and lymphoepithelioma-like carcinoma. Adenocarcinoma (5-15% of invasive carcinomas) shows an increasing trend in young females. Like its squamous counterpart, preinvasive and microinvasive versions are known. Variants such as mucinous, endometrioid, clear cell, mesonephric, serous, villoglandular and minimal deviation carcinoma are now defined. Adenosquamous carcinoma (5-25%), adenoid-cystic, adenoid-basal, neuroendocrine and undifferentiated carcinomas constitute other epithelial tumours of the cervix. The management of invasive cervical carcinoma remains heavily dependent on its stage. The FIGO staging system remains the most widely used. The 1995 update provides more definite criteria in subdividing stage IA tumours by delimiting stromal invasion of stage IA1 lesions to a maximum depth of 3 mm and a horizontal axis of 7 mm. In Malaysia, an appreciation of the cervical carcinoma problem has to take into consideration the population at risk, its multi-ethnicity, its socio-economic and geographical diversities and the constraints of the health care system. Females form 48.9% of the Malaysian population. 52.9% of them are in the sexually active age group of 15-50 years, indicating a significant population at risk for cervical carcinoma. Cervical carcinoma was the third most common cause of death due to solid tumours among Malaysian females in 1995 following carcinoma of the breast and respiratory tract. East Malaysia is predominantly rural with many communities having limited modern facilities. Such areas imply a lower educational and socio-economic status, raising the worry of a population at higher risk for developing cervical carcinoma. The population: doctor for Malaysia of 2153:1 compares poorly with nearby Singapore. Besides a shortage of doctors, there is also an uneven distribution of doctors, resulting in a ratio in East Malaysia of > 4000:1. Although Malaysia does not have a national cervical cancer-screening programme, many action plans and cancer awareness campaigns have been launched throughout the years, which appear to have made an impact as evidenced by the decreasing mortality rates from cervical carcinoma. Another interesting feature of cervical carcinoma in Malaysia relates to its multiethnic population. In Malaysian Chinese and Malay females, the prevalence of cervical carcinoma ranks second to breast cancer whereas the pattern is reversed in Malaysian Indian females. Studies into its aetiology and pathogenesis are being undertaken and may shed more light on this matter.

    Objectives: Pancreatic cancer is an aggressive silent killer with a median survival of a few months. It is the
    fourth leading cause of cancer death in the United States. The aim of this study was to evaluate the prognostic
    factors affecting the survival of patients with adenocarcinoma of the pancreas in Malaysia.
    Methods: This retrospective study examined 107 patients with adenocarcinoma of the pancreas from 2002
    to 2012 at University Malaya Medical Centre. The factors evaluated were age, sex, race, smoking habits,
    performance status, the presence of jaundice, pre-treatment CA 19.9 serum level, the location of a primary
    tumour, tumour grade, tumour staging and intent of treatment.
    Results: The median survival for the overall study population was 7.0 months (95% CI 5.1-8.8 months) with
    1, 3, and 5-year survival rates of 30.8%, 8.4% and 3.7% respectively. The survival was 16.1 months (95% CI
    7.7-24.4 months) for stage 1, 15.5 months (95% CI 8.1-22.8 months) for stage 2, 8.4 months (95% CI 6.1-10.8
    months) for stage 3, and 3.8 months (95% CI 2.9-4.7 months) for stage 4. In multivariate analysis, independent
    and unfavourable prognostic factors which retained significance were performance status, tumour stage and
    treatment intent.
    Conclusions: The biological characteristics are important as predictors of survival in patients with pancreatic
    cancer. Longer survival is possible if the disease is identified in its early stages with good performance status.
    Further development and evaluation of novel screening strategies need to be established to improve early
    detection of this disease.

    Breast self-examination (BSE) is a self-generated, non-invasive and non-irradiative method of breast cancer detection. This paper documents Malaysian women's awareness and practice of regular BSE as a potent breast cancer detection tool. A pre-test post-test questionnaire survey on women diagnosed with breast cancer (n=66) was conducted. Descriptive statistics and Chi-square tests were performed to correlate demographic variables, knowledge and regular practice of BSE. Findings showed that 80% of the breast cancer survivors self-detected the breast lumps, despite a high 85% of these women reporting they were never taught about BSE. More than 70% of the women maintained that lack of knowledge/skill on the proper practice of BSE was the key barrier to a more regular BSE practice. After an educational intervention on BSE and breast awareness, we found an increase report from 17% (at pre-test) to 67% (at post-test) of self reported monthly BSE practices. Provision of self-management education incorporating BSE, a readily available cheap method, should be introduced at primary care and breast clinics. This strategy promotes women's self-efficacy which contributes towards cancer control agenda in less resource available countries around Asia Pacific. Longer follow up may be crucial to examine the adherence to positive BSE behaviour.

    The main objective of this paper is to examine the psychometric properties of the Malay Version of the Hospital Anxiety and Depression Scale (HADS), tested on 67 husbands of the women who were diagnosed with breast cancer. The eligible husbands were retrieved from the Clinical Oncology Clinic at three hospitals in Kuala Lumpur, Malaysia. Data was collected at three weeks and ten weeks following surgery for breast cancer of their wives. The psychometric properties of the HADS were reported based on Cronbach' alpha, Intraclass Correlation Coefficients (ICC), Effect Size Index (ESI), sensitivity and discriminity of the scale. Internal consistency of the scale is excellent, with Cronbach's alpha of 0.88 for Anxiety subscale and 0.79 for Depression subscale. Test-retest Intraclass Correlation Coefficient (ICC) is 0.35 and 0.42 for Anxiety and Depression Subscale, respectively. Small mean differences were observed at test-retest measurement with ESI of 0.21 for Anxiety and 0.19 for Depression. Non-significant result was revealed for the discriminant validity (mastectomy vs lumpectomy). The Malay Version of the HADS is appropriate to measure the anxiety and depression among the husbands of the women with breast cancer in Malaysia.

    BACKGROUND: Cancer survival analysis is an essential indicator for effective early detection and improvements in cancer treatment. This study was undertaken to document colorectal cancer survival and associated prognostic factors in Malaysians.

    MATERIALS AND METHODS: All data were retrieved from the National Cancer Patient Registry Colorectal Cancer. Only cases with confirmed diagnosis through histology between the year 2008 and 2009 were included. Retrieved data include sociodemographic information, pathological features and treatment received. Survival curves were plotted using the KaplanMeier method. Univariate analysis of all variables was then made using the Logrank test. All significant factors that influenced survival of patients were further analysed in a multivariate analysis using Cox' regression.

    RESULTS: Total of 1,214 patients were included in the study. The overall 3 and 5year survival rates were 59.1% and 48.7%, respectively. Patients with localized tumours had better prognosis compared to those with advanced stage cancer. In univariate analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p=0.001) were found to be predictors of survival. None of the sociodemographic characteristics were found to exert any influence. In Cox regression analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p<0.001) were determined as independent prognostic factors of survival after adjusted for age, gender and ethnicity.

    CONCLUSIONS: The overall survival rate for colorectal cancer patients in Malaysia is similar to those in other Asian countries, with staging at diagnosis, primary tumor size, involvement of lymph node and treatment modalities having significant effects. More efforts are needed to improve national survival rates in future.

    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.

    Breast cancer is the most common cancer among women worldwide. Breast cancer metastasis primarily happens through lymphatic system, where the extent of lymph node metastasis is the major factor influencing staging, prognosis and therapeutic decision of the disease. We aimed to study the protein expression changes in different N (regional lymph nodes) stages of breast cancer. Protein expression profiles of breast cancerous and adjacent normal tissues were mapped by proteomics approach that comprises of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and tandem mass spectrometry (LC-MS/MS) analysis. Calreticulin and tropomyosin alpha 3 chains were the common up-regulated proteins in N0, N1 and N2 stages of breast cancer. Potential biomarker for each N stage was HSP 70 for N0, 80 k protein H precursor and PDI for N1 stage while 78 kDa glucose-regulated protein was found useful for N2 stage. In addition, significant up-regulation of PDI A3 was detected only in the metastasized breast cancer. The up-regulation expression of these proteins in cancerous tissues can potentially use as indicators for diagnosis, treatment and prognosis of different N stages of breast cancer.

    BACKGROUND:
    FDG-PET/CT is widely used in the management of a variety of malignancies with excellent overall accuracy, despite the potential for false positive results related to infection and inflammation.

    AIM:
      As cancer patients can develop clinically inapparent infections, we evaluated the prevalence and nature of incidental findings reported to be suggestive of infections that had been identified during clinical cancer staging with FDG-PET/CT.

    METHODS:
    The study involved a retrospective analysis of 60 patients managed primarily at our facility from a total of 121 cases identified as having possible infection on clinical reporting of more than 4500 cancer staging investigations performed during the calendar year of 2008.

    RESULTS:
    Occult infections were uncommon overall (≤1%), but most often because of pneumonia (31.6%), upper respiratory tract infections (21.1%) or wound infections (15.8%). Abnormal scans contributed to patients' management in 52.7% of cases. Two out of 13 patients whose scan abnormalities were not investigated further had worsening changes on repeated scan and one of these patients had clinical deterioration.

    CONCLUSIONS:
    In patients with FDG-PET/CT scans suggestive of infection and in whom a final diagnosis could be reached, the positive predictive value for FDG-PET/CT scans was 89% suggesting that abnormal scans indicative of infection should be investigated further in this population.
