    Congenital leukaemia (CL) is a rare malignancy that accounts for < 1% of cases of childhood leukaemias. Leukaemia cutis (LC) refers to cutaneous infiltration with leukaemic cells, and is seen in 30-50% of CL cases. It may precede, follow or occur simultaneously with leukaemia. If left untreated, the prognosis is usually poor, but early diagnosis and treatment may result in a favourable prognosis. We report a case of congenital leukaemia cutis with a progressive, violaceous papulonodular eruption (a 'blueberry muffin' rash), which had been noted at birth, as a presenting sign of acute myeloid leukaemia (AML), which on investigation was classified as AML, FAB M2 type with a t(8; 21)(p11;q22) chromosomal defect. The patient had a favourable response to AML chemotherapy.

    The incidence of thyroid cancer is increasing in several countries. The main objective of this retrospective study was to find and describe province-specific estimates of incidence in males and females by age groups for differentiated thyroid cancer (DTC). This study reports on 87 cases of DTC from Baluchistan province of Pakistan treated with post operative radioiodine at the Center for Nuclear Medicine and Radiotherapy (CENAR) Quetta from January 2003 to December 2009. The patient data has been collected from CENAR Quetta. Patients with DTC were confirmed by clinical examination, thyroid scintigraphy (Thyroid scan), blood tests (T3, T4, TSH) and histopathalogy tests and then treated with radioiodine. The Median age of the patients was 35.5 years (Range 12-70 years). The final histological diagnosis was papillary carcinoma in 71 (81.6 %) cases, follicular carcinoma in 6 (6.9%) cases while 10 (11.5%) cases presented with mixed papillary and follicular carcinoma. About 53 % cases were found in females with age 21-40 years. No strike predominance was observed in any age group for males. Four patients presented with recurrence while six patients showed metastasis in cervical lymph nodes. The small annual incidence did not follow any definite pattern. DTC has a small incidence in Baluchistan due to lack of education and health care facilities. The incidence of DTC is higher in females when compared with males as per this study. This preliminary study will provide an insight to incidence of DTC, its treatment facilities and future planning strategies in Baluchistan, Pakistan.

  4. Fulltext An unusual presentation of lymphoma of the head and neck region
    Teh CS, Chong SY
    Med J Malaysia, 2011 Aug;66(3):264-5.
    PMID: 22111456 MyJurnal
    A 33-year-old Malay lady presented to us with 1-month history of globus sensation in the throat. Clinically, she had a 3cmx2cmx1cm sessile soft mass arising from the right tongue base and was treated as hypertrophied lingual tonsil. Biopsy of the mass was done when the patient developed bleeding and was reported as diffuse non-Hodgkin's B-cell lymphoma. Globus sensation is a common complaint in the ORL clinic. It is important to be able to decide if further investigation is warranted to differentiate a malignant from a benign lesion as at times, a malignant lesion can masquerade as a harmless lesion.

    PMID: 22204190
    The case of a 10-year-old girl is presented who had a slow-growing, painless swelling on the left side of the tongue since six months. This was associated with disturbances in mastication and phonation. Examination revealed a 5 cm x 4 cm. globular smooth, mobile mass on left side of the tongue. There was no neurological deficit and no neck nodes palpable. She underwent excision of the mass under general anaesthesia. Complete enucleation with primary closure was carried out. The patient had an uneventful postoperative recovery and histological evaluation was consistent with schwannoma. The patient was recurrence free after one year.

  7. Fulltext Apoptosis in cancer: from pathogenesis to treatment
    Wong RS
    J Exp Clin Cancer Res, 2011;30:87.
    PMID: 21943236 DOI: 10.1186/1756-9966-30-87
    Apoptosis is an ordered and orchestrated cellular process that occurs in physiological and pathological conditions. It is also one of the most studied topics among cell biologists. An understanding of the underlying mechanism of apoptosis is important as it plays a pivotal role in the pathogenesis of many diseases. In some, the problem is due to too much apoptosis, such as in the case of degenerative diseases while in others, too little apoptosis is the culprit. Cancer is one of the scenarios where too little apoptosis occurs, resulting in malignant cells that will not die. The mechanism of apoptosis is complex and involves many pathways. Defects can occur at any point along these pathways, leading to malignant transformation of the affected cells, tumour metastasis and resistance to anticancer drugs. Despite being the cause of problem, apoptosis plays an important role in the treatment of cancer as it is a popular target of many treatment strategies. The abundance of literature suggests that targeting apoptosis in cancer is feasible. However, many troubling questions arise with the use of new drugs or treatment strategies that are designed to enhance apoptosis and critical tests must be passed before they can be used safely in human subjects.

    This study describes weight changes experienced by Malaysian women with breast cancer. Women with breast cancer (n=368) were recruited from eight hospitals and four breast cancer support groups in Peninsular Malaysia. Current weight was measured and weight at the time of diagnosis and a year preceding diagnosis were based on self-reports. Change in weight was determined from the year preceding breast cancer diagnosis to study entry (time 1), at the time of diagnosis to study entry (time 2) and from a year preceding breast cancer diagnosis to the time of diagnosis (time 3). Current body mass index, at a year preceding diagnosis and at the time of diagnosis were determined. Waist circumference was also measured. The sample comprised 57% Malay, 34% Chinese and 9.8% Indian women. The mean age of the women was 54 ∓ 9.04 years and over 80% were post-menopausal. Majority of the women were in stage I and stage II breast cancer at the time of diagnosis. The most common treatments received by these women were chemotherapy followed by radiotherapy and mastectomy. Overweight and obesity were prevalent in over 40% of the survivors at all three periods. Significant weight changes were observed during time 1 (-0.74 ∓ 4.78kg, p< 0.001), time 2 (2.73 ∓ 8.06kg, p< 0.001) and time 3 (3.47 ∓ 7.53kg, p< 0.001). At time 1, almost 50% showed no changes in their weight. At time 2, nearly two-thirds had gained weight and at time 3, 69% had gained weight, abdominal obesity was observed in nearly two-thirds of the women at study entry. A significant difference in weight change among age groups was observed in time 2 and time 3. All ethnic groups had significant weight change in time 1 and time 2. Significant weight gain was observed in relation to body mass index prior to diagnosis, at diagnosis and at study entry. However, no significant difference in weight change by educational level, family history of cancer and cancer stages were observed in all 3 periods. In conclusion, significant weight gain was evident in this sample of women after diagnosis of breast cancer and treatment. Women with breast cancer should be encouraged to maintain normal body mass index and waist circumference through appropriate diet and regular physical activity which may help to reduce their risk of recurrence, secondary cancer and metastasis.

  9. Cancer epidemiology and control in peninsular and island South-East Asia - past, present and future
    Moore MA, Manan AA, Chow KY, Cornain SF, Devi CR, Triningsih FX, et al.

    PMID: 20553070
    Malaysia, Brunei, Singapore, Indonesia, East Timor and the Philippines constitute peninsular and island South-East Asia. For reasons of largely shared ethnicity, with Chinese elements added to the basic Austromalaysian populations, as well as geographical contiguity, they can be usefully grouped together for studies of chronic disease prevalence and underlying risk factors. The fact of problems are shared in common, particularly regarding increasing cancer rates, underlines the necessity for a coordinated approach to research and development of control measures. To provide a knowledge base, the present review of available data for cancer registration, epidemiology and control was conducted. The most prevalent cancer site in males is the lung, followed by the liver, colon or the prostate in the majority of cases, while breast and cervical cancers predominate in most female populations. However, there are interesting differences among the racial groups, particularly regarding the stomach. General tendencies for increase in adenocarcinomas but decrease in squamous cell carcinomas and gastric cancer, point to change in environmental influence over time. Variation in risk factors depends to some extent on the level of economic development but overall the countries of the region face similar challenges in achieving effective cancer control. A major task is persuading the general populace of the efficacy of early detection and clinical treatment.

    PMID: 21265247 MyJurnal
    This paper validates the Brief COPE Scale in Malaysian women with breast cancer. Test-retest evaluation was undertaken at two/three weeks and ten weeks following surgery. Internal consistencies ranged from 0.25 to 1.00. Meanwhile, the Intraclass Correlation Coefficient (ICC) ranged from 0.05 to 1.00. Sensitivity of the scale was indicated by the mean differences as observed in most of the domains with Effect Size Index (ESI) ranged from 0 to 0.53. Significant differences between mastectomy and lumpectomy were observed for Active coping, Planning and Acceptance. Brief COPE Scale showed fairly good reliability and validity.

  11. Gene expression profiling and cancer-related pathways in type I endometrial carcinoma
    Saghir FS, Rose IM, Dali AZ, Shamsuddin Z, Jamal AR, Mokhtar NM
    Int. J. Gynecol. Cancer, 2010 Jul;20(5):724-31.
    PMID: 20973258
    INTRODUCTION: Malignant transformation of type I endometrium involves alteration in gene expression with subsequent uncontrolled proliferation of altered cells.

    OBJECTIVE: The main objective of the present study was to identify the cancer-related genes and gene pathways in the endometrium of healthy and cancer patients.

    MATERIALS AND METHODS: Thirty endometrial tissues from healthy and type I EC patients were subjected to total RNA isolation. The RNA samples with good integrity number were hybridized to a new version of Affymetrix Human Genome GeneChip 1.0 ST array. We analyzed the results using the GeneSpring 9.0 GX and the Pathway Studio 6.1 software. For validation assay, quantitative real-time polymerase chain reaction was used to analyze 4 selected genes in normal and EC tissue.

    RESULTS: Of the 28,869 genes profiled, we identified 621 differentially expressed genes (2-fold) in the normal tissue and the tumor. Among these genes, 146 were up-regulated and 476 were down-regulated in the tumor as compared with the normal tissue (P < 0.001). Up-regulated genes included the v-erb-a erythroblastic leukemia viral oncogene homolog 3 (ErbB3), ErbB4, E74-like factor 3 (ELF3), and chemokine ligand 17 (CXCL17). The down-regulated genes included signal transducer and activator transcription 5B (STAT5b), transforming growth factor A receptor III (TGFA3), caveolin 1 (CAV1), and protein kinase C alpha (PKCA). The gene set enrichment analysis showed 10 significant gene sets with related genes (P < 0.05). The quantitative polymerase chain reaction of 4 selected genes using similar RNA confirmed the microarray results (P < 0.05).

    CONCLUSIONS: Identification of molecular pathways with their genes related to type I EC contribute to the understanding of pathophysiology of this cancer, probably leading to identifying potential biomarkers of the cancer.

  12. Fulltext An audit of management of patients with borderline increased plasma-free metanephrines
    Anas SS, Vasikaran SD
    Ann. Clin. Biochem., 2010 Nov;47(Pt 6):554-8.
    PMID: 20926470 DOI: 10.1258/acb.2010.010131
    BACKGROUND: Measurement of plasma-free metanephrine plus normetanephrine (PFM) is the best screening test for phaeochromocytoma. While clearly raised levels are diagnostic, borderline increases may be associated with factors such as stress and medications, and should prompt a repeat study after interfering factors are withdrawn.
    METHODS: PFM results reported by a teaching hospital laboratory over a 12-month period were extracted from the laboratory information system. All borderline raised results were examined for a subsequent repeat test (as recommended by attached interpretative comment) and those not repeated were followed up by examination of case-notes or questionnaires to doctors.
    RESULTS: Of 111 patients with borderline increased PFM which did not normalize on repeat measurement, 33 were from the hospital and 78 from outside locations. Hospital notes for 27 out of 33 hospital-patients (82%) could be reviewed, and 49 completed questionnaires (63% of 78 sent out) were received from outside locations. Of these 76 patients thus followed up, the test was not repeated in 55 (72%) cases with borderline increased PFM. Of 10 patients with an adrenal mass and borderline PFM, only three had PFM repeated. Of another nine patients with undetermined final diagnosis and borderline PFM, only three had the test repeated.
    CONCLUSION: Seventy-two per cent of borderline increased PFM results were not followed up with appropriate repeat testing, potentially leading to missed detection of phaeochromocytoma. A stronger interpretative comment may encourage appropriate repeat testing in more cases with borderline increased PFM and suspected phaeochromocytoma.

  13. Fulltext The prevalence and assessment of ErbB2-positive breast cancer in Asia: a literature survey
    Tan YO, Han S, Lu YS, Yip CH, Sunpaweravong P, Jeong J, et al.
    Cancer, 2010 Dec 1;116(23):5348-57.
    PMID: 20715159 DOI: 10.1002/cncr.25476
    Overexpression of the epidermal growth factor receptor-related gene ErbB2 occurs in 18% to 25% of patients with breast cancer in Western countries and is associated with a poor prognosis. The prevalence of ErbB2-positive tumors in Asia is unclear, partly because data are limited. The objective of this review was to summarize the reported prevalence of ErbB2-positive tumors from a large sample of Asian patients and to examine ErbB2 assessment methods in Asia. From searches of MEDLINE, local language journals, and local and international conference proceedings as well as locoregional breast cancer experts' recommendations, the authors selected up to 5 studies each from India, Korea, Malaysia, the Philippines, Singapore, Taiwan, and Thailand that reported ErbB2 results based on assessment with immunohistochemistry (IHC) and/or fluorescence in situ hybridization (FISH). The reported prevalence of ErbB2-positive tumors in 22 studies on 24,671 patients, of whom 14,398 patients were assessed for ErbB2 status, varied widely (range, 6%-65%) as did the assessment methods used. Most studies (n=21) used IHC to assess ErbB2 status, but definitions for positivity varied. When robust assessment methods were used, the median prevalence was 19% based on strong IHC staining (IHC3+; n=9812 patients) and 25% based on FISH (n=681 patients). Data on the prevalence of ErbB2-positive breast cancer in Asia are limited. The current survey indicated that the prevalence in Asia may be similar to that in Western countries; thus, up to 1 in 4 Asian patients with breast cancer potentially could benefit from ErbB2-targeted treatment. A standard, reliable ErbB2 assessment method available to patients across Asia is urgently required.

    PMID: 19852334 MyJurnal
    The Malaysian National Cancer Registry (NCR) report for the period 2003-2005 shows an incidence of stomach cancer of 2.2 for Malay, 11.3 for Chinese and 11.9 for Indian males per 100,000 population. Malay (1.3), Chinese (7.2) and Indian (7.2) women have rates lower than men. Malays in Peninsular Malaysia have five times less stomach cancer than Chinese and Indians. This racial difference is more marked than that noted in the Singapore cancer registry. Regional data from Kelantan has an even lower rate for Malays there (1.5 for males and 0.9 for females per 100,000 population). The incidence of Helicobacter pylori infection, a known risk factor for stomach cancer, is low among Malays.

    Haemangiopericytoma (HPC) is a rare vascular tumor arising from the pericytes of Zimmermann and is characterized by its unpredictable and variable biological behavior. These tumors are common in the trunk and the extremities and less than 16% of the cases occur in the head & neck region. Its occurrence in the oral cavity and pharynx is uncommon. We report an extremely rare case of haemangiopericytoma of the oropharynx arising from the tonsillo-lingual sulcus as a pedunculated mass, which was successfully excised perorally after a preliminary tracheostomy. No recurrence has been noted on a follow-up of more than six years.

    PMID: 19803307
    Laryngeal hemangiomas are relatively rare. Laryngeal hemangiomas occur in two main forms--infantile and adult laryngeal hemangiomas. While infantile hemangiomas are usually found to occur in the subglottis, adult hemangiomas occur commonly in the supraglottic regions of the larynx. Laryngeal hemangioma with cavernous features isolated to the free edge of the vocal fold is a very rare clinical finding. We present a case of hemangioma of the right vocal cord in an adult, which was managed successfully in our center.

    PMID: 19958401 DOI: 10.1111/j.1440-172X.2009.01797.x
    Cancers and related treatments have devastating effects on psychosexual life of patients. This study helps us to understand the cultural perspectives of 50 Asian women diagnosed with cancer. Median age was 50+ years. Median duration of time from diagnosis to interview was 23 months. Thirty-eight per cent stopped sex before illness, 36% stopped sex completely whereas 18% stopped gradually after diagnosis; 8% continued to have sex till time of interview. Overall, 70% were living with spouse but not engaged in sexual intercourse; 31.4% slept in different room, 48.6% slept in the same room but without any form of sexual contact. Thirty-eight per cent believed sexual activity could cause cancer recurrence, and 30% believed cancer could be sexually transmitted. Eighty-two per cent reported acceptance of changes to physical appearance. Approximately 70-86% did not discuss sexuality with their doctor or spouse; 90% agreed doctors should ask about psychosexual issues on a routine basis. Approximately 74.4% reported good cooperation from spouse. Cultural beliefs of Asians pose as barriers to providing and receiving psychosexual affection between women diagnosed with cancer and their spouse. However, these beliefs also serve as protective factors in their mutual acceptance of change in psychosexual activities. Health-care professionals need to be sensitive to the vast cultural differences in psychosexual expressions and needs of women diagnosed with cancer.

    PMID: 20084779
    We report here a case of primary colorectal T-cell lymphoma of the cecum in a 30-year-old man. Patient presented with a history of abdominal pain, fever, vomiting and hematochezia. Clinical examination was unremarkable and colonoscopy showed an ulcerating mass in the colon. A right hemicolectomy with dissection of the paracolic lymph nodes was performed. The final histopathological examination showed a primary T- cell lymphoma of the cecum. Staging didn't show any involvement in any other sites of the body. Primary colon lymphoma is a rare gastrointestinal tumor that represents less than 1% of the gastrointestinal lymphomas. Peripheral T-cell lymphoma represents a relatively small proportion of lymphomas and has a lower prevalence in Western countries. The risk factors, clinical presentation, staging, prognostic factors and treatment modalities of extra-nodal lymphoma are discussed.

    PMID: 18333303 DOI: 10.1177/101053950701900309
    Naturalistic inquiry using focus group interviews was undertaken to explore experiences and perceived barriers to self management in women with breast cancer. The aim was to identify their perceived barriers to self management to aid the development of rehabilitation programmes. Successful programmes are strongly linked to patients' perceived needs. Four focus groups consisted of 39 women, were purposively recruited. Women's needs within the three areas of medical, emotional and role management of breast cancer were explored. The main barriers were unavailability of information, inability to access services-and-support, and socioeconomic-cultural issues (entrenched myths, low-socioeconomic status, and inadequate insurance-health legislative coverage). The findings provide the critically lacking 'expert-view' of survivors, who verified the importance of the medical, emotional and role management tasks, and highlighted barriers and structural solutions. With breast cancer becoming recognised as a form of chronic illness, this study is timely.
