METHODS: 3317 raw digital mammograms were processed with Volpara(®) (Matakina Technology Ltd, Wellington, New Zealand) to obtain fibroglandular tissue volume (FGV), breast volume (BV) and VBD. Errors in parameters including CBT, kVp, filter thickness and mAs were simulated by varying them in the Digital Imaging and Communications in Medicine (DICOM) tags of the images up to ±10% of the original values. Errors in detector gain and offset were simulated by varying them in the Volpara configuration file up to ±10% from their default values. For image noise, Gaussian noise was generated and introduced into the original images.
RESULTS: Errors in filter thickness, mAs, detector gain and offset had limited effects on FGV, BV and VBD. Significant effects in VBD were observed when CBT, kVp, detector offset and image noise were varied (p
PATIENTS AND METHODS: A total of 11 cases of malignant phyllodes were retrospectively reviewed between Nov 2014 and Oct 2017.
RESULTS: The median age was 45 years old (31- 61 years). The median pathological tumor size was 10.5cm (2-28cm). 6 patients (55%) were premenopausal. 7 patients (64%) were treated eventually with mastectomy and 4 (36%) were treated with breast conserving surgery. 4 (36%) patients had Axillary Clearance done while axillary sampling was done in 2 patient. The remainder 5 (45%) required axillary clearance at a later op. 6 (55%) patients received postoperative radiotherapy. After a median follow up period of 11 months (range 4-33 months), 8 developed local recurrence. The overall 2 year survival rate was 18%.
CONCLUSION: Malignant Phyllodes tumors are rare tumors that occur in fairly young women, when compared with the adenocarcinoma of the breast. They tend to grow to reach large with absence of nodal metastasis. Ultimately surgery is the mainstay of management but with postoperative radiotherapy it can decrease the local recurrence rates in certain presentations however recurrence rate is high and overall survival rates are poor.
METHODS: The qualitative phenomenological approach involving working mothers in Kota Bharu who fulfilled the inclusion criteria and consented to participate in the study were recruited using purposive sampling. Sixteen participants aged 24 to 46 years were interviewed using semi-structured in-depth interviews in the study. All interviews were recorded in digital audio, transcribed verbatim and analyzed using thematic analysis.
FINDINGS: Three main themes emerged from the data analysis: perception of breastfeeding, challenges in breastfeeding, and support for breastfeeding. Two subthemes for perceptions were perception towards breastfeeding and towards infant formula. Challenges had two subthemes too which were related to perceived insufficient milk and breastfeeding difficulty. Where else, two subthemes for support were internal support (spouse and family) and external support (friends, employer, and healthcare staff).
CONCLUSIONS: Maintaining breastfeeding after return to work is challenging for working mothers and majority of them need support to continue breastfeeding practice. Support from their spouses and families' influences working mothers' decision to breastfeed. Employers play a role in providing a support system and facilities in the workplace for mothers to express and store breast milk. Both internal and external support are essential for mothers to overcome challenges in order to achieve success in breastfeeding.
