Factors associated with HER2 overexpression in breast cancer: Experience in an Asian developing country

Tan GH, Choo WY, Taib NA, Yip CH

Asian Pac J Cancer Prev, 2009;10(5):837-40.
PMID: 20104975

INTRODUCTION: The HER2 gene is amplified in up to 30% of human breast cancers, leading to overexpression of the HER2 protein on the cell surface. Overexpression of HER2 is associated with a more aggressive cancer and hence a poorer overall survival.
OBJECTIVE: To evaluate the association between clinico-pathological features and HER2 overexpression in breast cancer.
METHODS: This is a retrospective study conducted in the Department of Surgery, University Malaya Medical Centre. The association between HER2 overexpression, determined by immunohistochemistry, and other clinicopathological factors was evaluated in 996 patients with newly diagnosed breast cancer treated from 2005 to 2007 using univariate and multivariate logistic regression.
RESULTS: HER2 overexpression occurred in 30.3% of patients. On bivariate analysis, HER2 overexpression was inversely related to ER expression (p<0.01) and PR expression (p<0.01). This overexpression was associated with a higher tumour grade, lymphovascular positivity and infiltrating ductal carcinoma subtype. On multivariate analysis, HER2 overexpression was significantly associated with higher tumour grade (p= 0.018, CI 1.25-11.04), PR negativity (p= 0.002, CI 0.30-0.77) and lymphovascular positivity (p= 0.042, CI 1.01-2.12).
CONCLUSIONS: HER2 overexpression was observed in 30.3% of Malaysian female breast cancer patients. This group of patients represents a more aggressive subtype of breast cancer with higher tumour grade, PR negativity and lymphovascular positivity. No significant relationship was established between HER2 overexpression and age, race, lymph node, ER, pathology subtype and stage of disease from this study.

Hassan BA, Yusoff ZB, Othman SB

Asian Pac J Cancer Prev, 2009 Oct-Dec;10(4):641-4.
PMID: 19827886

INTRODUCTION: Neutropenia has a detrimental effect on cancer patients' quality of life, also possibly resulting in a reduction in the chemotherapy dose which could lead to an increment in the size of a cancer. The main danger associated with neutropenia is the risk of bacterial, fungal or viral infection, which may lead to patient death. Treatment including granulocyte-colony stimulating factors (G-CSF, filgrastim) so as to increase the body immunity is given to neutropenic patients with no infection i.e., absence of fever. However, when infection is present, antibiotics such as ceftazidime, imipenem and vancomycin need to be used.

OBJECTIVE: The aim of this study was to find the association between neutropenia severity and treatment with filgrastim (Neupogen) alone or in combination with antibiotics in solid cancer patients.

METHODS: This is an observational retrospective study on 117 cases suffering from neutropenia after chemotherapy administration. The patients were admitted to a government hospital for cancer treatment between the years 2003-2006. The types of data collected were categorical and not normally distributed, covering demography, chemotherapy, severity of neutropenia (classified on absolute neutrophil count into mild, moderate and severe) and treatment of neutropenia, either filgrastim (Neupogen) alone or in combination with antibiotics. Statistical tests used were the Chi-square test, Fisher's exact test and logistic regression.

RESULTS: The majority (69.2%) of the patients were treated with filgrastim (81) alone, only 30.8% receiving the combination. Significant associations between both treatments and neutropenia severity. Both Chi-square and Fisher's exact tests showed P= 0.001. Logistic regression showed that filgrastim is the major treatment for severe neutropenic patients since the result showed an infinity (E) and P= 0.001 for filgrastim alone more than its combination with antibiotic.

CONCLUSION: The use of filgrastim is highly associated with treatment of severe neutropenia in solid cancer patients who received chemotherapy. So filgrastim is considered as the drug of choice in the presence of severe neutropenic cases.

Fulltext E-cadherin expression correlates with histologic type but not tumour grade in invasive breast cancer

Nurismah MI, Noriah O, Suryati MY, Sharifah NA

Asian Pac J Cancer Prev, 2008 Oct-Dec;9(4):699-702.
PMID: 19256762

The traditional classification of infiltrating breast carcinomas into ductal and lobular can be diagnostically challenging in a small proportion of cases with equivocal histological features and in in-situ lesions with overlapping features. Distinguishing between the infiltrating ductal (IDC) and lobular (ILC) carcinomas is clinically important because of the different pattern of systemic metastases and prognostic evaluation. E-cadherin is a potentially useful immunohistochemical marker which may serve to differentiate between the two tumour types. We therefore studied E-cadherin expression in 32 cases of breast carcinomas comprising 16 IDCs and 16 ILCs. The correlation between E-cadherin expression and the histological grade of IDCs was also analysed. Our results showed complete loss of E-cadherin expression in all ILCs, while the IDCs consistently showed variable E-cadherin positivity. No significant correlation was found between E- cadherin expression and the histological grade of IDCs. We conclude from this study that E-cadherin is a useful marker to differentiate between IDC and ILC of the breast. A larger study of IDCs is now needed to further evaluate the correlation between E-cadherin and tumour grade to estimate its prognostic potential.

Fulltext Utility of Ki-67 and p53 in distinguishing cervical intraepithelial neoplasia 3 from squamous cell carcinoma of the cervix

Tan GC, Sharifah NA, Shiran MS, Salwati S, Hatta AZ, Paul-Ng HO

Asian Pac J Cancer Prev, 2008 Oct-Dec;9(4):781-4.
PMID: 19256776

The differentiation between cervical intraepithelial neoplasia 3 (CIN 3) and early squamous cell carcinoma (SCC) of the cervix may be difficult in certain situations. Identification of invasion beyond the basement membrane is the gold standard for the diagnosis of the latter. The objective of this study was to determine whether the use of Ki-67 and p53 could help in solving the above dilemma. This was a retrospective study on 61 cases of cervical neoplasms comprising of 25 cases of CIN 3 and 36 SCC. All cases were evaluated by immunohistochemistry using Ki-67 and p53 monoclonal antibodies. Results showed that the differences of Ki-67 and p53 expression between CIN 3 and SCC were statistically significant. In conclusion, Ki-67 and p53 may serve as helpful adjuncts to routinely-stained histological sections in differentiating between CIN 3 and SCC.

Othman NH, Zin AA

Asian Pac J Cancer Prev, 2008 Oct-Dec;9(4):747-51.
PMID: 19256771

OBJECTIVE: Kelantan in Malaysia has a high prevalence of diabetes and colorectal cancer is also on the rise. This study is to determine the association of metabolic diseases, particularly diabetes type 2 [DM2] and hypertension, with colorectal cancer patients in our population.

METHODS: This retrospective study was conducted on all colorectal carcinomas in Hospital Universiti Sains Malaysia (HUSM) in Kelantan from ythe ears 2001-2006. The data were retrieved from the Registry in Pathology laboratory and the clinical details from the patients' clinical records and analyzed using SSPS Version 12.0, with a value of p<0.05 taken to be statistically significant.

RESULTS: 138 CRC cases with complete clinical records were included. The age ranged from 16.0 to 88.0 years, with a mean of 56.9 -/+ SD 15.4. The male 90(65%) to female 48(35%) ratio was 1.7:1.0 and 47.8% were suffering from metabolic diseases; 18(13.0%) with Diabetes Mellitus Type 2(DM2), and 48(34.8%) with hypertension (HT). Diabetes Type 2 and hypertension also demonstrated significant association (p<0.05) with the stage and the site of the cancer. Patients with diabetes type 2 88.8%(16/18) and Hypertension 85.4% (41/48) were strongly associated with cancers located in the distal to transverse colon (p<0.001).

CONCLUSION: There is a high proportion of metabolic diseases; hypertension and diabetes type 2 among colorectal carcinomas seen in Kelantan population. In this preliminary study we noted a strong association of metabolic diseases with the stage and site of the cancer. To reduce CRC incidence, the high prevalence of DM2 in Kelantan needs to be addressed.

Fulltext Budesonide/formoterol combination therapy as both maintenance and reliever medication in moderate-to-severe asthma: a real-life effectiveness study of Malaysian patients

Loh LC, Lim BK, Raman S, Vijayasingham P, Mohd Yusuf S

Med J Malaysia, 2008 Aug;63(3):188-92.
PMID: 19248687

Budesonide/Formoterol (Symbicort) combination therapy as both maintenance and reliever treatment (SMART) is a novel approach in asthma management. We examined its 'real-life effectiveness' in treating Malaysian patients with moderate-to-severe asthma in whom despite on combined inhaled corticosteroids and long-acting beta2-agonist, were still inadequately controlled. In a retrospective study, 22 eligible adult patients on SMART [mean (range) age: 49 (36-65) years; FEV1: 41 (21-74)% predicted] were identified from medical records of an urban-based university hospital chest clinic, and their clinical outcomes studied at three months. Another 16 patients [50 (14-66) years; 48 (20-91)% predicted] of similar severity and treatment (i.e. Symbicort maintenance treatment plus short-acting beta2-agonist as reliever), but not on SMART, were used as comparator over the same assessment period. In addition, the patients were separately interviewed with standard questionnaire on their satisfaction and compliance to the SMART approach. In SMART group, rescue treatment requirement (p<0.001) and FEV1 [median difference = 2.5%, p=0.015; mean difference: 90 ml, p=0.013] showed significant improvement while in comparator, there was significant improvement only in the requirement for rescue treatment (p=0.023). Hospital admission rates were significantly reduced in SMART group compared to the other (p=0.039), but not in emergency treatment. Five patients asked to discontinue SMART while all others were satisfied, compliant and perceived improvement of their asthma with SMART. The maximum daily doses of inhaled budesonide and formoterol were 1400 microg and 31.5 microg respectively. Our preliminary findings suggest that SMART approach can be attempted as an effective and safe treatment option for patients with inadequately controlled moderate-to-severe asthma in Malaysian setting.

Fulltext Does the pre-operative value of serum CA15-3 correlate with survival in breast cancer?

Velaiutham S, Taib NA, Ng KL, Yoong BK, Yip CH

Asian Pac J Cancer Prev, 2008 Jul-Sep;9(3):445-8.
PMID: 18990019

INTRODUCTION: CA15-3 is a well-known tumour marker for breast cancer. Currently it is not recommended for screening or diagnosis of breast cancer and its main application is in monitoring response to treatment in women with metastatic breast cancer. The aim of this study was to correlate serum CA15-3 at presentation with the stage of disease and overall survival in women with breast cancer in the University Malaya Medical Centre.

METHODS: This is a retrospective study of 437 women who had CA15-3 levels determined at initial presentation of breast cancer to UMMC between Jan 1999 and Oct 2003.

RESULTS: Of those patients who were adequately staged, CA15-3 was found to be elevated (defined as >51 U/ml) in 0% of Stage 1, 7.9% of Stage 2, 36.7% of Stage 3 and 68.6% of Stage 4 cases. In a subset of 331 patients with survival data, patients with normal CA15-3 had a 85% five year overall survival rate compared to 38% in their counterparts with elevation of the tumor marker. The level of elevation was also significantly related to survival; patients with values more than 200 U/ml exhibited only a 28% five year survival. The association of elevated CA15-3 at initial presentation with poor outcome was maintained over univariate and multivariate analyses.

CONCLUSION: Estimation of CA15-3 at presentation of breast cancer is important as it is an independent prognostic indicator and may prompt the physician to investigate for metastases if elevated.

Motorcycle casualties represent significant number in road traffic accidents in Malaysia, and among all the injuries, facial injuries pose many significant problems physiologically, functionally, and aesthetically. The aim of this study was to analyze the pattern of maxillofacial as well as other injuries in motorcyclists who were seen at Hospital Universiti Kebangsaan Malaysia.Patients' records from January 2004 to December 2005 were reviewed. Data related to demographics, vehicle/object involved in collision, involvement as a rider or pillion, whether a helmet was worn or not, location of injuries on the face/facial bones, and other associated injuries were collected.A total of 113 cases of motorcycle accidents were recorded; 106 males and 7 females were involved. Mean age was 25.8 years. Among all the races, Malay had the highest involvement (72.3%), followed by Chinese (14.3%), Indians (8.9%), and others (5.4%). The types of collision were either a single-vehicle collision (i.e., skidded) or with another vehicle/s or object (e.g., tree, stone, or lamppost). The injuries were mainly seen on the lower face (46.9%) followed by midface (25.7%) and a combination of the midface and lower face (15%) and others (12.4%). The most frequent other associated injuries recorded were orthopedic and head injuries.

Al-Jashamy K, Al-Naggar RA, San P, Mashani M

Asian Pac J Cancer Prev, 2009;10(6):1159-62.
PMID: 20192603

OBJECTIVE: The objective of this study was to determine the histopathological features and cell morphology of various cervical lesions observed among Malaysian women.
METHODOLOGY: A retrospective study was conducted to evaluate 77 cervical cases collected from the histopathology laboratory of Ipoh hospital from 1st January, 2005, to 31st December, 2006.
RESULTS: Cervical intraepithelial neoplasia (CIN) was found in 33 (42%) cases, CIN III accounting for 27%, and CIN I, CIN II and CIN II-III 5% each. The highest rate for CIN cases was 43% in the 41-50 year age group and the lowest rate was 6% in the group aged 61-70 years. Non-keratinizing and metastatic squamous cell carcinomas (SCCs) accounted for 16% and 13%, respectively, the combination being second in majority (29%), followed by adenocarcinoma (17%). The histopathological results showed CIN I to be characterized by mild papillary projections of the epithelium with some degree of nuclear enlargement, pleomorphism, mild koilocytosis, bionucleated cells and a low nucleo-cytoplasmic ratio. CIN II demonstrated typical squamous epithelium with disorganization of the lower part of the epithelium accompanied by nuclear hyperchromatism, an increased nucleo-cytoplasmic ratio, and scanty mitotic figures. CIN III was characterized by pleomorphic nuclei, atypical cells with mitotic figures, nucleo-cytoplasmic ratio, anisokaryosis and hyperchromasia.
CONCLUSION: Lesions related to cervical cancer showed tumor progression correlating with histopathological changes in cell morphology.

Fulltext CD44 expression and axillary lymph node metastasis in infiltrating ductal carcinoma of the breast

Looi LM, Cheah PL, Zhao W, Ng MH, Yip CH

Malays J Pathol, 2006 Dec;28(2):83-6.
PMID: 18376796 MyJurnal

Metastasising ability connotes one of the most important life-threatening properties of malignant neoplasms. Recent studies indicate that CD44 proteins, multifunctional cell adhesion molecules which contribute to "homing" of lymphocytes to lymph nodes as well as cell-cell and cell-matrix interactions, are potential markers of tumour progression. However, whether CD44 expression by human tumours contribute to increased metastatic risk remains controversial. In an attempt to clarify its role in breast cancer, we have investigated the correlation between CD44 expression by breast carcinoma and the presence of axillary lymph node metastases. CD44 expression was detected using a standard immunoperoxidase method on formalin-fixed, paraffin-embedded, primary infiltrating ductal breast carcinoma tissues taken from 60 female patients who underwent mastectomy with axillary node clearance. Tumours were graded according to the modified Bloom and Richardson criteria. 62% of patients had histologically-proven lymph node metastasis. 40% of primary cancers exhibited cytoplasmic membrane immunopositivity for CD44. 46% of primary tumours which have metastasied to axillary lymph nodes were CD44 positive whereas 30% of tumours which have not metastasised expressed CD44. CD44 positivity was expressed by 20% of grade 1, 31% grade 2 and 58% grade 3 tumours. Our results suggest that CD44 may have a role in the progression of breast cancer and emphasise the need to investigate its interaction with other mechanisms of cancer advancement.

Ng SS, Kwan MK, Ahmad TS

Med J Malaysia, 2006 Dec;61 Suppl B:13-7.
PMID: 17600987

This study is designed to evaluate twenty patients after sural nerve harvest using the single longitudinal incision method. The area of sensory loss to pin prick was assessed by the authors at different intervals. Donor site factors, scar cosmesis, functional status and complications were assessed using a questionnaire. The mean area of anaesthesia at one month was 65 cm2 and it had reduced by 77% to 15 cm2 at one and a half years. The mean area of reduced sensation was 49 cm2 at one month and it increased by 18% to 58 cm2 over the same period. Therefore, the total area of sensory deficit was reduced by 36% from 114 cm2 at one month to 73 cm2 at one and a half years. Subjective patient evaluation indicated moderate level of pain during immediate post surgical period, which reduced significantly at one month. A low level of neuroma symptoms was recorded throughout the study period. At a mean follow-up period of two years, there was no area of anaesthesia in 50% of the patients. Mean area of anaesthesia for all patients was 12 cm2 and mean area of reduced sensation was 55 cm2. Subjective patient evaluation indicated a low level of pain, neuroma symptoms and numbness over the sural nerve sensory distribution. Twenty five percent of the patients were not satisfied with the scar appearance. Function and daily activities were not affected significantly. No surgical complications were observed.

Fulltext Use of gentamicin impregnated POP discs for antibiotic pouch dressing

Lau CP, Chee EK, Thirumal M

Med J Malaysia, 2006 Dec;61 Suppl B:32-6.
PMID: 17600990

Antibiotic pouch technique is commonly used due to the high local antibiotic concentration and moist environment for wound healing. We used locally made gentamicin impregnated Plaster of Paris discs in treating wounds with exposed deep structures like tendons and bones. Out of 22 patients treated with this method, 19 completed treatment. Granulation tissue formed quickly and effectively covered the exposed structures. All wounds either healed by secondary intention or became suitable for split skin grafting. Gentamicin impregnated Plaster of Paris disc pouch dressing is safe, cost saving, and effective for management of deep open wounds.
