INTRODUCTION: HER2 test result depends on a good quality histological section of the breast specimen. Laboratories that process specimens using sophisticated and molecular testing should receive suitable specimen for more accurate results and less waste of expensive resources.
METHODS: A questionnaire based on the ASCO-CAP Guidelines for HER2 testing was developed and administered to pathologists from the local laboratories of Metro Manila-Philippines tertiary referral hospitals. Questionnaire responses were analyzed using descriptive statistics.
RESULTS: Most laboratories did quality control/quality assessment monitoring for the pre-analytic, analytic,post-analytic and turn¬around time phases. Many transported their specimens from the operating room to the laboratory
CONCLUSION: Even in standardized procedures, small variations in sample processing for IHC and FISH can still occur. Inexperienced laboratories will have greater problems interpreting HER2 status results. Laboratories should look into their system in handling specimens for an accurate HER2 testing towards quality assurance.

INTRODUCTION: The difficulty of obtaining accurate and reproducible assessment of HER2 status in the Philippines, despite the predictive value of the test for HER2 positive breast cancer patients, may be sufficiently addressed if an effective multidisciplinary approach to HER2 testing is carried out. This may be accomplished by identifying disparities and similarities in HER2 testing for breast cancer.
METHODS: This is a cross-sectional study which included medical oncologists who had used trastuzumab for HER2-positive patients. Surgeons, who belonged to the same tertiary hospital as the medical oncologists were also interviewed. The survey questionnaires were administered via face-to-face, mail, or fax. Responses were kept confidential. Questionnaire responses were analysed using summary statistics.
RESULTS: There were 35 medical oncologists and 37 surgeons - 93% stated that all women diagnosed with breast cancer should be tested for HER2 at the point of diagnosis; 61% stated that the greatest barrier to initiating HER2 testing was inadequate patient funds. 57% medical oncologists and 65% surgeons believed that HER2 testing for all breast cancer patients at the point of clinical diagnosis was being observed at their hospital. 69% stated that medical oncologists or surgeons should request for HER2 test whoever saw the patients first; 59% stated that whoever saw the patient first provide the patient information about HER2 testing whereas 28% stated it is the medical oncologist who should provide information about HER2 testing. 47% medical oncologist and 63% surgeons stated that surgeons should arrange for breast tissue sample collection; 27% medical oncologists and 20% surgeons stated that pathologists should do this.
CONCLUSION: Medical oncologists and surgeons were similar in the opinion that all women diagnosed with breast cancer should be tested for HER2 at the point of diagnosis, financial capability was the greatest barrier for initiating HER2 testing, and whoever saw the patient first should provide patient education. There was disparity on who should request and who should arrange for tissue collection.

INTRODUCTION: A multidisciplinary approach is essential to optimize patient care. In the practice of oncology, surgeons, medical oncologists, and pathologists are essential for the histology-based diagnosis of cancer patients. In breast cancer, hormone receptor and HER2 positivity are both predictive and prognostic, and so testing for these has been strongly recommended for every newly diagnosed breast cancer patient. A unique but meaningful information that can be provided by medical oncologists, as customers, is their satisfaction to the services (e.g. HER2 testing) and product (e.g. reports) of the pathology laboratory. Any quality initiative effort to improve HER2 testing can also be extended to hormone receptor (ER/PR) testing. This study measures the general satisfaction of medical oncologists practicing in Metro Manila with local HER2 testing services and reports.
METHODS: This cross-sectional study had survey questionnaires distributed to medical oncologists practicing in Metro Manila chosen on the basis of their considerable experience with requesting HER2tests and with the use of anti-HER2 therapy in their management of breast carcinoma patients. Demographics, practice information, rating of satisfaction per laboratory service category, and a checklist of elements of IHC/FISH reports were collected.
RESULTS: 32 medical oncologists participated in the survey, most of whom were from tertiary hospitals. Breast carcinoma cases make up around 26-50% of cancer cases in their practice. More than half request HER2 testing for their breast cancer patients. Medical oncologists are generally satisfied with the services for IHC and FISH HER2 testing (composite scores >2) provided by the laboratories. Overall, medical oncologists were very satisfied with diagnostic accuracy and completeness of relevant information in the report. Laboratory services were mostly rated good, with the exception of pathologists' responsiveness to problems and notification of equivocal results. For both IHC and FISH, patient/physician identification, date of service, specimen identification/ site/ type, results, and interpretation were reported to be included in the reports. However, time to/duration of/ type of fixation, method and image analysis method, antibody clone/ vendor, and comment that an FDA-approved method was used, were reported missing by the many.
CONCLUSION: For both IHC and FISH, overall satisfaction was found to be moderately directly correlated with diagnostic accuracy. In a country like the Philippines where quality initiatives of laboratories may still be far from ideal, medical oncologists can demand inclusion of their preferences into assessments processes by laboratories and correct assumptions of laboratory managers as to what element of the services and products they value most. Measurement of customer satisfaction can be integrated into the quality assurance programs of laboratories and corresponding hospitals.
