    A 60-year-old Chinese lady presented with a left flank mass and weight loss. Plain films showed a sclerotic L1 vertebral body, osteopenic L2 and L3 vertebral bodies and loss of left psoas outline. However initially unrevealed history of previous carcinoma of the cervix caused confusion as to the aetiology of a sclerotic vertebral body associated with an left flank collection. Psoas abscess with adjacent bony osteomyelitis was initially suspected. The left flank mass turned out to be an infected necrotic large metastatic lymph node compressing the lower pole of the left kidney. The sclerotic and osteopenic vertebral bodies represented an unusual presentation of bony cervical carcinoma metastases.

    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.

    Carcinosarcoma is a highly aggressive and infiltrative tumor. A finding of this tumor in a paranasal sinus is exceedingly rare. We describe the case of a 61-year-old man who presented with a mass on the left side of his face. The mass was excised via a total maxillectomy with a modified radical neck dissection. Histologic analysis identified a mixture of carcinomatous and sarcomatous components. Within 1 month of surgery, the patient developed a sternal metastasis, and he died within a short period of time. The aggressive nature of this tumor and its metastases demand early diagnosis and prompt treatment.

    BACKGROUND: Breast cancer is the commonest cancer affecting women world wide. Breast cancer is a leading cause of cancer related mortality in Asian countries. Management of breast cancer depends on several tumour-related and patient related factors. HER-2/neu over-expression has been associated with a poor prognosis in breast cancer. We assessed HER-2/neu over expression pattern in unselected breast cancer cases in terms of clinico-pathologic parameters to identify any associations between them.

    METHODS: Two hundred cases of breast cancer were evaluated at Advanced Medical and Dental Institute and Hospital Kepala Batas from 2002 to 2007. HER-2/neu status was confirmed in breast cancer tissues by immunohistochemistry. Immunohistochemical expression of HER-2/neu was evaluated according to the published scoring guidelines of the 'Hercep Test' (Dako, Carpinteria, CA). Data were analysed to identify any association between HER-2/neu and clinico-pathologic parameters.

    RESULTS: HER-2/neu over expression was found in 63 (31.5%) tumours out of 200. When assessed for various age groups no significant association was found. However, a high percentage (75%) of over-expression was noted in the 81-85 years age group. No association was found with different racial groups (Malay, Chinese and Indians), with lymph node status or with grade of tumour. However a positive association was observed with oestrogen receptor and progesterone receptor expression.

    CONCLUSION: There was no association between HER-2/neu over expression and age, race, lymph node status or tumor grade. However a positive association was found with oestrogen and progesterone receptor status.

    OBJECTIVE: The objective of this study was to identify the characteristics of oral cancer among Malay patients in Hospital Universiti Sains Malaysia (HUSM), Kelantan.

    METHODS: A retrospective record review was conducted from August to December 2006 in HUSM. Of 133 patients with oral cancer diagnosed from 1986 to 2005, 118 were Malay. Data on socio-demographic background, high-risk habits practiced, clinical and histological characteristics, and treatment profile of the patients were obtained.

    RESULTS: Malay patients with oral cancer were predominantly elderly, aged 60 years old and above (51.7%) at the time of diagnosis, with a mean age of 58.1 years (SD 16.81). Most patients were males (64.4%) and the majority of them were married (83.9%). More than half (58.5%) had been smokers, and of those who smoked, 89.9% were males. Some had a betel quid chewing habit (22.9%) but none ever consumed alcohol. The majority of the patients (77.1%) were diagnosed at stage IV. The tongue was the most usual site involved (37.3%) and squamous cell carcinoma was the most common histological type seen (75.4%).

    CONCLUSIONS: The prevalence of oral cancer among Malay patients in HUSM is high (88.7%). It is predominantly found in elderly males and the majority of cases present at advanced stage.

    The HER2 codon Ile655Val and Cyclin D1 (CCND1) G870A polymorphisms were analyzed in a hospital-based Malaysian population using PCR-RFLP method. Peripheral blood samples were collected from 230 breast cancer patients, and 200 normal and healthy women who had no history of breast disease or breast cancer. We evaluated the association between HER2 or CCND1 polymorphisms and breast cancer risk, and clinico-pathological parameters in the population. The genotype and allele frequencies of HER2 (P=0.163 vs P=0.0622) and CCND1 (P=0.377 vs P=0.284) polymorphisms were not significantly different between the breast cancer cases and normal subjects, respectively. Women who were Ile/Val heterozygotes (OR=1.48; 95% CI, 0.91-2.43), Val/Val homozygotes (OR=1.93; 95% CI, 0.51-7.77) and carriers of Val allele genotype (OR=1.53; 95% CI, 0.95-2.45) were not significantly associated with increased breast cancer risk. Similarly, women who were homozygous (OR=1.34; 95% CI, 0.77-2.34) or heterozygous (OR=0.98; 95% CI, 0.60-1.60) for A allele, or carriers of A allele genotype (OR=1.10; 95% CI, 0.70-1.73) were not associated with breast cancer risk. Analysis on clinico-pathological parameters showed that Val allele genotype was significantly correlated with nodal metastases but A allele genotype was not associated with any of the variables. Our findings suggest that the polymorphic alleles of HER2 and CCND1 may not play an important role as genetic markers for breast cancer risk, but presence of Val allele may be useful for tumor prognosis.

    Lymph node excision biopsy is commonly carried out for the investigation of lymphadenopathy. The objective of this study is to elucidate the pattern of nodal pathology seen in a private pathology practice. A total of 137 nodal biopsies for primary investigation of nodal enlargement were retrieved from the files in a private diagnostic pathology laboratory in the year 1997. Lymph nodes excised for cancer staging were excluded from this study. The histology was reviewed based on H&E stained sections, and with additional histochemical and immunoperoxidase stains when deemed necessary. Cases of malignant lymphomas were sub-classified with the aid of further immunophenotyping using a panel of monoclonal and polyclonal lymphoid antibodies. One case was excluded from this study due to inadequate tissue for further assessment. There were 58 males and 78 females, giving a ratio of 1:1.3 in the remaining 136 cases. They consisted of 13 Malays (M), 108 Chinese (C), 14 Indians (I) and 1 other ethnic group (O). The ratio of M:C:I:O was 1:8.3:1.1:0.1. The majority of the cases were in the age range of 20 to 50 years. The pathology consisted of 17 (12.5%) malignant lymphomas [6 Hodgkin's lymphoma, 11 non-Hodgkin's lymphoma], 35 (25.7%) metastatic carcinomas, 45 (33.1%) reactive hyperplasia, 19 (13.9%) tuberculosis, 11 (8.2%) Kikuchi's disease and 9 (6.6%) others (Castleman's disease 2, cat scratch disease 2, Kimura's disease 1, sarcoidosis 1, non-specific lymphadenitis 3). All categories of nodal disease showed approximately similar ratio of ethnic and gender distribution as above, except for Kikuchi's disease, for which 100% of the patients were female. The most common site of biopsy was from the head and neck region, particularly the cervical group of nodes. The most common nodal pathology seen in the private laboratory was reactive hyperplasia, followed by metastatic carcinoma. Malignant lymphoma constituted only 12.5% of the cases.

    An 86-year-old man presented with a painless, pea-sized growth over the left angle of his jaw, which had been gradually enlarging over two years. A clinical diagnosis of pilar cyst was made. Histopathological examination of the mass revealed a malignant proliferating trichilemmal tumour. During follow-up 4 months later, a palpable small upper jugular lymph node was noted at the left side of the neck. Biopsy revealed a metastatic malignant trichilemmal tumour. This case illustrates a rare malignant tumour which is a challenge to clinical diagnosis.

    The case of a minor salivary gland tumour, arising from the tongue, with nodal metastasis is presented. Biopsy of the tumour and fine-needle aspiration cytology of the neck swelling showed the presence of a clear cell carcinoma with evidence of nodal metastases. A commando operation was performed and the defect was reconstructed using a local tongue flap. The literature review indicated that the neoplasm was rare and its site of occurrence rather unusual.

    Histopathological features in 89 cases of Stage 1B and early 2A invasive carcinoma of the cervix who underwent Wertheim radical hysterectomy and pelvic lymphadenectomy were studied. Depth of tumour invasion and lymphatic/vascular space permeation by tumour cells were significantly associated with lymph node metastases. The other features such as tumour type, and stromal leucocytic reaction showed no significant relationship to the presence of lymph node metastases.

    Introduction: Oral squamous cell carcinoma (OSCC) is a major health problem worldwide. The overall survival rate remains at 50% despite numerous studies and various treatment modalities in OSCC. The presence of lymph node metastasis in OSCC is well established as an independent prognostic factor. This present study aims to investigate the association of four tumour antigens; FJX-1, GNα12, IFITM3 and MAGED4B with the sociodemographic and clinicopathological parameters of OSCC. The potential use of these markers as a prognostic indicator of patient sur-vival and lymph node metastasis in OSCC was explored. Methods: 35 cases of OSCC with available formalin-fixed paraffin-embedded (FFPE) specimens involving the tongue, buccal mucosa, gingiva, alveolus and floor of mouth were evaluated by immunohistochemistry for FJX-1, GNA12, IFITM3 and MAGED4B expression. Assessment of the expression of these tumour antigens was based on the cellular sub-site, intensity and percentage of staining in the OSCC samples. Results: The expression of all four tumour markers were expressed in all samples (n=35) but none statistically associated with any clinicopathological or socio-demographic parameters. Survival analysis using Kaplan-Meier test showed high expression of GNA12, IFITM3 and MAGED4B individually with poor prognosis in OSCC patients. A combination of markers, GNA12 and MAGED4B demonstrated a significant association with pa-tient survival in OSCC (p=0.014). Multivariate analysis after adjustment for selected socio-demographic factors (age, gender, risk habits and sub-sites of the oral cavity) revealed that high expression of both MAGED4B and GNA12 remained as an independent prognostic factor for poor prognosis in OSCC (HRR =5.231, 95% CI 1.601,17.084; p=0.006). Conclusion: We concluded that high combined expression of both marker (Gα12 and mAGED4B) might be used as an independent prognostic indicator in OSCC.

    INTRODUCTION: Hedgehog (HH) pathway is an important signalling cascade for growth and patterning during embryonic development. Constitutive activation of Hedgehog pathway can be found in various types of malignancies including medulloblastoma, basal cell carcinoma, gastrointestinal, breast, pancreatic, prostate cancer and leukaemia. Little is known about the expression and role of Hedgehog signalling in bladder cancer.

    MATERIALS AND METHODS: The purpose of this study was to investigate the immunohistochemical expression of SMO in 112 bladder cancer cases and determine their association with demographic and clinicopathological parameters. Bladder cancer tissues were obtained from the Hospital Kuala Lumpur.

    RESULTS: SMO was expressed in the cytoplasm of all cases of bladder cancer. 6 cases (5.4%) showed low expression, while 106 cases (94.6%) showed high expression. Positive expression of SMO protein was correlated with a few variables which include grade and stage of tumour, lymph node metastasis and distant metastasis. SMO expression showed statistically significant association with higher grade (p=0.001) and higher stage (p=0.042) of bladder cancer. SMO expression also showed borderline association with lymph node metastasis (p=0.056).

    CONCLUSION: These findings indicate that SMO expression may be a poor prognostic marker in bladder cancer.

    Breast cancer is the most common malignancy among females in Malaysia. Attempts have been made to investigate the association between breast cancer and human leukocyte antigen (HLA) types. However, data from those previous studies are highly variable. The aim of this study is to investigate the association between HLA-A types and clinicopathological factors in breast cancer. The frequencies of HLA-A type in 59 female patients with infiltrating ductal of the breast were determined by polymerase chain reaction method. HLA-A2/A30 and A2/A31 haplotype (5.1%; P = 0.045) as well as HLA-A30 (5.1%, P = 0.045) and A31 (6.8%; P = 0.020) allele were significant higher in the patients than controls (0%). HLA-A24 allele was negatively related to lymph node metastasis (r = -0.316; P = 0.021) whereas, A26 (r = -0.430; P = 0.001) and A36 (r = -0.430; P = 0.001) alleles were negatively correlated to distant metastasis in breast cancer. Negative correlations between HLA-A26/A36 (r = -0.430; P = 0.001), A2/A11 (r = -0.276; P = 0.044), A24/A34 (r = -0.430; P = 0.001) haplotypes and distant metastasis were identified. Interestingly, Her2 expression in breast carcinoma was negatively correlated to A11/24 haplotypes (r = -0.294; P = 0.034) but positively correlated to homozygous HLA-A24 (r = 0.396; P = 0.040). In conclusion, HLA-A2, -A30 and A31 were associated with breast cancer.

    Testicular cancer is an uncommon malignancy of the male reproductive organ, accounting for 1% of all cancers in men. Distant cervical metastasis from testicular cancer has been reported in 5% of patients. We present 2 cases of non-seminomatous testicular cancers that were diagnosed retrospectively in patients who presented with pure cervical lymph nodes. A comprehensive approach bearing in mind the possible differentials, pathogenesis and treatment options are discussed.

    Introduction: Therapeutic nodal dissection is still the mainstay of treatment for patients with lymph node metastases in many centres. The local data, however, on the outcome of therapeutic LND remains limited. Hence, this study aims to inform practice by presenting the outcomes of LND for thyroid cancer patients and our experience in a tertiary referral centre.

    Methods: This is a single-centre retrospective observational study in a Malaysian tertiary endocrine surgery referral centre. Patients who underwent total thyroidectomy with lymph node dissection between years 2013 and 2015 were included and electronic medical records over a 3-year follow-up period were reviewed. The outcomes of different lymph node dissection (LND), including central neck dissection, lateral neck dissection, or both, were compared.

    Results: Of the 43 subjects included, 28 (65.1%) had Stage IV cancer. Among the 43 subjects included, 8 underwent central LND, and 15 had lateral LND while the remaining 20 had dissection of both lateral and central lymph nodes. Locoregional recurrence was found in 16 (37.2%) of our subjects included, with no statistical difference between the central (2/8), lateral (7/15), and both (7/20). Postoperative hypocalcaemia occurred in 7 (16.3%) patients, and vocal cord palsy occurred in 5 (11.6%), whereas 9 patients (20.9%) required reoperation. Death occurred in 4 of our patients.

    Conclusion: High recurrence and reoperative rates were observed in our centre. While the routine prophylactic LND remains controversial, high risk patients may be considered for prophylactic LND. The long-term risk and benefit of prophylactic LND with individualised patient selection in the local setting deserve further studies.

    OBJECTIVE: The role of HMG-CoA reductase (HMGCR) in relation to prognostic and treatment predictive information of HER2 positive breast cancer has been newly explored. In this study, we aimed to determine the expression of HMGCR in HER2 immunohistochemistry (IHC) scores of 2+ and 3+ breast cancer and to correlate with the patients' outcomes.

    METHODOLOGY: Using a cross-sectional design, invasive breast carcinoma of no special type (NST) and HER2 IHC scores of 2+ and 3+ cases were selected over a 50-month period in Hospital Sultanah Bahiyah (HSB), Alor Setar. IHC staining for HMGCR was performed on paraffin-embedded tissues at the Pathology Laboratory, Hospital Universiti Sains Malaysia (HUSM), Kubang Kerian using the standard staining procedure. The results were correlated with the patient's demographic and clinicopathological data.

    RESULTS: A total of 59 cases of HER2 IHC 2+ and 3+ invasive breast carcinoma were identified. The cases were predominant in young Malay women with tumours smaller than 50mm, higher grade and positive for lymphovascular invasion, axillary lymph nodes involvement and ER/PR expressions. HMGCR was positively expressed in HER2 IHC 2+ and 3+ breast cancer cases, which the staining intensities varied from weak, moderate to strong. Majority of the cases were scored 1+ for HMGCR expression. A low-positive HMGCR was more likely to be associated with less favourable outcomes of patients with HER2 IHC 2+ and 3+. However, the associations were statistically not significant.

    CONCLUSION: A study in a larger cohort of tumour samples is needed to further validate HMGCR expression as a potential prognostic biomarker for HER2 positive breast cancer. It is also suggested that all the HER2 IHC 2+ and 3+ cases need to be gene amplified using FISH analysis.

    Follow-up of colorectal carcinoma after therapy is based on symptoms, tumor markers, and imaging studies. Clinicians sometimes face diagnostic dilemmas because of unusual presentations on the imaging modalities coupled with rising serum markers. We report a case of colorectal carcinoma that presented with gastrointestinal symptoms 14 months after completion of treatment. Investigations showed rise in carcinoembryonic antigen (CEA). Suspecting disease recurrence, complete radioimaging workup was performed; the only abnormality detected was a smooth, hypodense area in the posterior third of the spleen on contrast-enhanced computed tomography abdomen. In view of the previous diagnosis of carcinoma colon, the symptoms reported by the patient, the elevated CEA, and the atypical CECT appearance, a diagnosis of splenic metastasis was made. The patient was subjected to splenectomy as a curative treatment. However, the histopathological report revealed it to be a splenic infarct. The present case reemphasizes the limitations of radiological studies in the follow-up of carcinoma colon.

    BACKGROUND: Nasopharyngeal carcinoma (NPC) is the fourth most common cancer in Malaysia. The objective of this study was to determine the five-year survival rate and median survival time of NPC patients in Hospital Universiti Sains Malaysia (USM).

    METHODS: One hundred and thirty four NPC cases confirmed by histopathology in Hospital USM between 1st January 1998 and 31st December 2007 that fulfilled the inclusion and exclusion criteria were retrospectively reviewed. Survival time of NPC patients were estimated by Kaplan-Meier survival analysis. Log-rank tests were performed to compare survival of cases among presenting symptoms, WHO type, TNM classification and treatment modalities.

    RESULTS: The overall five-year survival rate of NPC patients was 38.0% (95% confidence interval (CI): 29.1, 46.9). The overall median survival time of NPC patients was 31.30 months (95%CI: 23.76, 38.84). The significant factors that altered the survival rate and time were age (p=0.041), cranial nerve involvement (p=0.012), stage (p=0.002), metastases (p=0.008) and treatment (p<0.001).

    CONCLUSION: The median survival of NPC patients is significantly longer for age≤50 years, no cranial nerve involvement, and early stage and is dependent on treatment modalities.
