    Breast cancer is the most common female cancer and the commonest cause of death due to cancer for women in Malaysia. This study was performed to identify the relationship with lifestyle factors. A case-control study was conducted among females with breast cancer who came for treatment to the Breast Clinic Hospital Kuala Lumpur in July until September 2004. A total of 203 female patients were recruited as cases along with 203 patients who attended the Outpatient Clinic, Hospital Kuala Lumpur during the study period as the controls. The study showed women who did not exercise regularly to have four times higher risk (adjusted odds ratio is 3.49, 95% CI is 1.84 to 6.62) compared to those who exercised regularly. Women with a high fat diet were also at elevated risk (adjusted odds ratio 3.84, 95% CI is 1.20 to 12.34) compared to those consuming a low fat diet. Women without breast cancer generally had a longer duration of lifetime lactation with a median of thirty-three months compared to women with breast cancer (twenty months, p<0.05). Women who did not take oral contraceptive pills but had breast-fed their child have a 56.0% lower risk (crude odds ratio 0.44, CI is 0.22 to 0.87) compared to women who did not take oral contraceptive pill and also did not breast-feed their child. If they had breast fed for thirteen months and above, they faced a 61.0% lower risk (crude odds ratio 0.39, 95% CI is 0.17 to 0.87). There was a significant inverse trend for lifetime lactation and breast cancer risk. In conclusion certain life styles of women are associated with a higher risk of breast cancer development. Therefore, the promotion of a healthy life style should be emphasized.

    A comparative multicenter clinical trial of two low-dose combined oral contraceptives (OCs) was conducted in Malaysia, Egypt, Thailand, and Mexico. Efficacy, safety and acceptability were investigated in women taking either a norgestrel-based (NG) OC or a norethindrone acetate-based (NA) OC. This paper includes analysis of 892 women, all of whom were at least 42 days but within 26 weeks postpartum and randomly allocated to one of the above OCs. Follow-up visits were scheduled at 1, 4, 8 and 12 months after admission. Baseline sociodemographic characteristics were similar for both groups, as well as compliance. There were nine unintended pregnancies reported; eight of these occurring in the NA group. Adverse experiences were minor with headaches and dizziness being the most common complaints; frequency of reports was similar in both groups. The group taking the NG-based OC had significantly (p < .05) fewer menstrual-related complaints. Discontinuations due to menstrual problems were significantly more common among NA users (primarily amenorrhea). Discontinuations in the NG group were primarily for other personal reasons, e.g. unable to return to the clinic. There was also a significant difference between the two groups for the 11-month gross cumulative life table discontinuation rates due to menstrual problems (p < .01); the NA group had the higher rate.

    MyJurnal
    Migraine with aura is one of the major subtypes of migraine, and can be associated with ischaemic brain infarction. Use of oral contraceptive pills (OCPs) increases the risk of infarction in this type of migraine. Seizures and migraine also have a complex relationship, one element of which is migraine- triggered seizures. We report a case of bilateral occipital lobe infarction and migraine-triggered seizures, most likely precipitated by oral contraceptive pills (OCPs) in a patient with migraine with visual aura. OCPs, triptans and ergotamines should be used cautiously in these patients. Methods of birth control other than OCPs should be considered.

  6. Fulltext The association between new generation oral contraceptive pill and the development of inflammatory bowel diseases
    Sanagapalli S, Ko Y, Kariyawasam V, Ng SC, Tang W, de Silva HJ, et al.
    Intest Res, 2018 Jul;16(3):409-415.
    PMID: 30090040 DOI: 10.5217/ir.2018.16.3.409
    Background/Aims: To examine the association between use of oral contraceptive pills (OCPs) and the risk of developing inflammatory bowel diseases (IBD), in a modern cohort.

    Methods: A prospective nested case-control study across sites in the Asia-Pacific region was conducted; involving female IBD cases and asymptomatic controls. Subjects completed a questionnaire addressing questions related to OCP use. Primary outcome was the risk of development of IBD of those exposed to OCP versus non-exposure. Secondary outcomes were development of Crohn's disease (CD) versus ulcerative colitis (UC), and whether age of first use of OCP use may be associated with risk of IBD.

    Results: Three hundred and forty-eight female IBD cases (41% CD, median age: 43 years) and 590 female age-matched controls were recruited. No significant association was found between OCP use and the risk of IBD (odds ratio [OR], 1.65; 95% confidence interval, 0.77-3.13; P=0.22), CD (OR, 1.55) or UC (OR, 1.01). The lack of association persisted when results were adjusted for age and smoking. IBD cases commenced OCP use at a younger age than controls (18 years vs. 20 years, P=0.049).

    Conclusions: In this large cohort of subjects from the Asia-Pacific region, we found a modest but not significantly increased risk of developing IBD amongst OCP users.

  7. Predictors of breast cancer among women in a northern state of Malaysia: a matched case-control study
    Matalqah L, Radaideh K, Yusoff ZM, Awaisu A
    Asian Pac J Cancer Prev, 2011;12(6):1549-53.
    PMID: 22126497
    BACKGROUND: Breast cancer has been increased in South East Asia countries, but there are limited data for breast cancer risk factors in these countries. To clarify the risk for breast cancer among the Malaysian women, a matched case-control study was conducted.

    METHOD: Between October 2009 and April 2010, a survey was prospectively conducted among women admitted to clinics of Penang General Hospital for examination and/or treatment by using a questionnaire. Therefore, characteristics of patients diagnosed with breast cancer (n=150) were compared with control cases (n=150) admitted to hospital for non-neoplastic, non-hormone related diseases.

    RESULTS: Family history of a distant relative with breast cancer (OR=2.84), history of first-degree relatives with breast cancer (OR=2.95), history of benign breast disease (OR=2.43), menstrual irregularity (OR=4.24), and use of oral contraceptive pills (OCP) (OR=2.15) were found to be significant risk factors for breast cancer in our population. Furthermore, education more than 11 years (OR=0.40), breastfeeding (OR=0.50), being employed (OR=0.45) and practicing low fat diet (OR=0.53) were strongly protective against breast cancer development.

    CONCLUSION: The results emphasize the importance of conducting a series of awareness campaigns that highlights the protective role of longer breastfeeding period against breast cancer and the negative relationships between OCP use and high fat diet with this disease.

    PMID: 12229348
    PIP: Family planning in Malaysia is discussed. Family planning began in Malaysia about 15 years ago through the efforts of voluntary family Planning Associations in the various Malay states. In 1966 the Malaysian Parliament passed the National Family Planning Act setting up the National FAmily Planning Board to formulate policies and methods for the promotion and spread of family planning knowledge and practice on the grounds of health of mothers and children and welfare of the family. In 1967, the board set a target of 40,000 new acceptors of family planning and 90% of the target was reached. This represents 3% of the child-bearing married women aged 15-49. The target for 1968 of 65,000 new acceptors is being achieved. A survey of acceptors is to be carried out from December 1968 to April 1969 to ascertain how many women who accepted family planning continue to practice it. Malaysia's crude birth rate declined from 46.2 in 1957 to 37.3 in 1966 before the government program was instituted. Abortion attempts have been frequent. The main method of contraception used is oral contraceptives. According to a 1957 survey, 31% of the married women in the metropolitan areas and 2% of rural women were using contraception. Presently, in Malaysia there is a need to: 1) train personnel to provide services, 2) inform and motivate families to accept family planning, 3) continue a broad educational program, 4) reform Malaysia's antiquated abortion law, and 5) integrate family planning services more fully into the general health services of the country.

    PMID: 12268570
    PIP: The initial results of a study conducted to develop guidelines for the clinical management of family planning acceptors with regard to return of fertility following contraceptive use, are presented. 193 parous women attending an urban family planning clinic were interviewed regarding their last pregnancy conceived after stopping a method of contraception. The average interval to pregnancy was 3.9, 2.8 and 1.8 months for ex-users of oral pills, intrauterine devices and conventional methods of contraception, respectively, with median delays to conception of 1.9, 1 and within the 1st month for the 3 categories. In comparison, 149 women who had not used any method at all took 7.3 months before becoming pregnant. Selected variables including age and parity, duration of use and problems encountered, and outcome of pregnancy are further analysed. Follow-up investigations and treatment are recommended 12 months after stopping oral pills and 6 months after removal of intrauterine device for those who have not yet conceived.

    PMID: 12316339
    A study was conducted on a total of 100 women attending the Family Planning Clinic in Kuala Lumpur. 50 took combined low-dose estrogen and progesterone pills for a year or more and the other 50 used different methods of birth control. Platelet aggregation, ATP release, Thromboxane B2, and 6-keto-prostaglandin F1alpha estimations were made to evaluate the effect of oral contraceptives (OCs) on platelet function and prostanoid production. The results showed no significant differences in the parameters measured in the 2 groups investigated. These findings are comparable to those reported by other studies, suggesting relatively low risk, if any, of thrombosis in OC users.

  14. Fulltext Reproductive and hormone-related risk factors for epithelial ovarian cancer by histologic pathways, invasiveness and histologic subtypes: Results from the EPIC cohort
    Fortner RT, Ose J, Merritt MA, Schock H, Tjønneland A, Hansen L, et al.
    Int J Cancer, 2015 Sep 01;137(5):1196-208.
    PMID: 25656413 DOI: 10.1002/ijc.29471
    Whether risk factors for epithelial ovarian cancer (EOC) differ by subtype (i.e., dualistic pathway of carcinogenesis, histologic subtype) is not well understood; however, data to date suggest risk factor differences. We examined associations between reproductive and hormone-related risk factors for EOC by subtype in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Among 334,126 women with data on reproductive and hormone-related risk factors (follow-up: 1992-2010), 1,245 incident cases of EOC with known histology and invasiveness were identified. Data on tumor histology, grade, and invasiveness, were available from cancer registries and pathology record review. We observed significant heterogeneity by the dualistic model (i.e., type I [low grade serous or endometrioid, mucinous, clear cell, malignant Brenner] vs. type II [high grade serous or endometrioid]) for full-term pregnancy (phet  = 0.02). Full-term pregnancy was more strongly inversely associated with type I than type II tumors (ever vs. never: type I: relative risk (RR) 0.47 [95% confidence interval (CI): 0.33-0.69]; type II, RR: 0.81 [0.61-1.06]). We observed no significant differences in risk in analyses by major histologic subtypes of invasive EOC (serous, mucinous, endometrioid, clear cell). None of the investigated factors were associated with borderline tumors. Established protective factors, including duration of oral contraceptive use and full term pregnancy, were consistently inversely associated with risk across histologic subtypes (e.g., ever full-term pregnancy: serous, RR: 0.73 [0.58-0.92]; mucinous, RR: 0.53 [0.30-0.95]; endometrioid, RR: 0.65 [0.40-1.06]; clear cell, RR: 0.34 [0.18-0.64]; phet  = 0.16). These results suggest limited heterogeneity between reproductive and hormone-related risk factors and EOC subtypes.

  17. Value of subcutaneous fat in predicting ovulation day
    Jamaludin J, Nordin NM, Mohamad N, Etta KM
    Malays J Reprod Health, 1988 Jun;6(1):65-9.
    PMID: 12281593
    Subcutaneous body fat and Quetelet's Indices (QI) of 52, 18-29 year old normal female volunteers were determined. These body mass indices were then grouped according to the phase of each subject's menstrual cycle, early or late follicular and early or late luteal phase. The subcutaneous body fat is 27.07 +or- 1.0% in the early follicular but drops to 24.68 +or- 1.84% in the late follicular phase. The value then rises significantly higher than that in the late follicular phase to 30.14 +or- 1.15% (P0.02) in the early luteal drops to 27.17 +or- 0.55% towards the level of the early follicular phase (P0.05). Variations in the values of QI during each menstrual cycle exactly mirror those for subcutaneous body fat. The fall in the 2 body mass indices during the late follicular phase coincides somewhat with the established preovulatory LH and FSH surges as well as the high levels of estrogen of this period. On the other hand the significant rise in the 2 parameters during the early luteal phase coincides with the marked rise in the ratio of progesterone to estrogen. Clearly, increased levels of progesterone relative to estrogen appear to cause an increase in the body fat during each menstrual cycle. The implication of this finding for women on contraceptive pills which are predominantly progesterone and those whose normal menstrual cycle is "interrupted" at the early luteal phase by a successful fertilization raises very interesting questions with regards to prediction of ovulation.

    PMID: 12343151
    A study of knowledge, attitude and practice was carried out among sixty nine married Orang Asli women in the district of Kuaia Langat. The study showed that oniy a smail proportion of the women were using family planning methods. About half of the study women were stiil uncertain with regards to their attitude towards family planning. The findings aiso showed that there was no diversity of the methods with oral contraceptive being the major choice. Majority of the husbands had indeed positive feeling towards family planning. The women also considered breastfeeding as a major method of contraception.
    PIP: A knowledge-attitude-practice (KAP) study of 69 married Orang Asli women from Kuala Langat district, Malaysia is reported. The Orang Asli comprise 2744 people in 412 households served by rural health services and a few private practitioners. The median age of the sample was 16.3 years, of whom 18.8% were married before age 15. 47.8% knew of family planning methods. 53.6% of the women said that they and their husbands approved of family planning, 2.9% disapproved, and the rest were undecided. Only 30.4% had discussed family planning with their husbands. 21.7% stated that they would use contraception, either the pill or sterilization, after their family was completed.

  19. Fulltext Reproductive factors and epithelial ovarian cancer survival in the EPIC cohort study
    Bešević J, Gunter MJ, Fortner RT, Tsilidis KK, Weiderpass E, Onland-Moret NC, et al.
    Br J Cancer, 2015 Dec 01;113(11):1622-31.
    PMID: 26554655 DOI: 10.1038/bjc.2015.377
    BACKGROUND: Reproductive factors influence the risk of developing epithelial ovarian cancer (EOC), but little is known about their association with survival. We tested whether prediagnostic reproductive factors influenced EOC-specific survival among 1025 invasive EOC cases identified in the European Prospective Investigation into Cancer and Nutrition (EPIC) study, which included 521,330 total participants (approximately 370,000 women) aged 25-70 years at recruitment from 1992 to 2000.

    METHODS: Information on reproductive characteristics was collected at recruitment. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), and multivariable models were adjusted for age and year of diagnosis, body mass index, tumour stage, smoking status and stratified by study centre.

    RESULTS: After a mean follow-up of 3.6 years (±3.2 s.d.) following EOC diagnosis, 511 (49.9%) of the 1025 women died from EOC. We observed a suggestive survival advantage in menopausal hormone therapy (MHT) users (ever vs never use, HR=0.80, 95% CI=0.62-1.03) and a significant survival benefit in long-term MHT users (⩾5 years use vs never use, HR=0.70, 95% CI=0.50-0.99, P(trend)=0.04). We observed similar results for MHT use when restricting to serous cases. Other reproductive factors, including parity, breastfeeding, oral contraceptive use and age at menarche or menopause, were not associated with EOC-specific mortality risk.

    CONCLUSIONS: Further studies are warranted to investigate the possible improvement in EOC survival in MHT users.

  20. Fulltext Exogenous hormone use and cutaneous melanoma risk in women: The European Prospective Investigation into Cancer and Nutrition
    Cervenka I, Al Rahmoun M, Mahamat-Saleh Y, Fournier A, Boutron-Ruault MC, Severi G, et al.
    Int J Cancer, 2020 Jun 15;146(12):3267-3280.
    PMID: 31506954 DOI: 10.1002/ijc.32674
    Evidence suggests an influence of sex hormones on cutaneous melanoma risk, but epidemiologic findings are conflicting. We examined the associations between use of oral contraceptives (OCs) and menopausal hormone therapy (MHT) and melanoma risk in women participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is a prospective cohort study initiated in 1992 in 10 European countries. Information on exogenous hormone use at baseline was derived from country-specific self-administered questionnaires. We used Cox proportional hazards regression models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). Over 1992-2015, 1,696 melanoma cases were identified among 334,483 women, whereof 770 cases among 134,758 postmenopausal women. There was a positive, borderline-significant association between OC use and melanoma risk (HR = 1.12, 95% CI = 1.00-1.26), with no detected heterogeneity across countries (phomogeneity = 0.42). This risk increased linearly with duration of use (ptrend = 0.01). Among postmenopausal women, ever use of MHT was associated with a nonsignificant increase in melanoma risk overall (HR = 1.14, 95% CI = 0.97-1.43), which was heterogeneous across countries (phomogeneity = 0.05). Our findings do not support a strong and direct association between exogenous hormone use and melanoma risk. In order to better understand these relations, further research should be performed using prospectively collected data including detailed information on types of hormone, and on sun exposure, which may act as an important confounder or effect modifier on these relations.
