RESUMO

PURPOSE: Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during the gestational period (gp-PABC) or in the first postpartum year (pp-PABC). Despite its infrequent occurrence, the incidence of PABC appears to be rising due to the increasing propensity for women to delay childbirth. We have established the first retrospective registry study of PABC in Ireland to examine specific clinicopathological characteristics, treatments, and maternal and foetal outcomes. METHODS: This was a national, multi-site, retrospective observational study, including PABC patients treated in 12 oncology institutions from August 2001 to January 2020. Data extracted included information on patient demographics, tumour biology, staging, treatments, and maternal/foetal outcomes. Survival data for an age-matched breast cancer population over a similar time period was obtained from the National Cancer Registry of Ireland (NCRI). Standard biostatistical methods were used for analyses. RESULTS: We identified 155 patients-71 (46%) were gp-PABC and 84 (54%) were pp-PABC. The median age was 36 years. Forty-four patients (28%) presented with Stage III disease and 25 (16%) had metastatic disease at diagnosis. High rates of triple-negative (25%) and HER2+ (30%) breast cancer were observed. We observed an inferior 5-year overall survival (OS) rate in our PABC cohort compared to an age-matched breast cancer population in both Stage I-III (77.6% vs 90.9%) and Stage IV disease (18% vs 38.3%). There was a low rate (3%) of foetal complications. CONCLUSION: PABC patients may have poorer survival outcomes. Further prospective data are needed to optimise management of these patients.

RESUMO

PURPOSE: Around 30% of patients with breast cancer will develop brain metastases (BM). We sought to characterize the disease course, treatments and outcome for our patient cohort. MATERIALS AND METHODS: We extracted clinicopathological data from electronic records from January 2015 to December 2020. Results were generated using SPSS statistics v27. RESULTS: We identified 98 patients. Median overall survival (OS) from BM diagnosis was 3 months [hormone receptor (HR)+/human epidermal growth factor receptor 2 (HER2)-], 8 months [HR+/HER2+], 7 months [HR-/HER2+] and 2 months [triple negative breast cancer (TNBC)]. Whole brain radiotherapy (WBRT) (n=48, 70%) was most frequently used followed by surgery (n=15, 22%) and stereotactic radiosurgery (n=6, 8%). In patients who received WBRT alone (n=40) the median OS post WBRT was 2.6 months. CONCLUSION: After BM development, half of the patients had systemic therapy and 70% had local therapy, but only the HER2 subgroup had a prolonged OS likely reflecting central nervous system (CNS) activity of anti-HER2 drugs. TNBC patients had the worst prognosis. Although our cohort is small, OS was >1 year for 60% of HER2+ patients who received trastuzumab emtansine after BM development, which is encouraging for antibody drug conjugates and CNS activity. Patients who received WBRT had a higher burden of CNS disease and had an OS of less than 3 months.

RESUMO

BACKGROUND: The COVID-19 pandemic has resulted in radical changes in the delivery of healthcare worldwide. Our oncology service (at an Irish national cancer centre) rapidly transitioned to the use of telemedicine or virtual clinics (VC) to minimise potential risk of exposure to COVID-19 amongst an immunosuppressed, high-risk population. Our study aimed to evaluate the use of VC in this setting. METHODS: An 18-point questionnaire was designed to investigate the patient experience of VC during the COVID-19 pandemic in Ireland and compliance with guidelines developed in Ireland to conduct VC and the role of VC in the future. Questionnaires were distributed following the receipt of verbal consent from patients during the VC. Descriptive statistics were utilised for data analysis using SPSS®. RESULTS: One hundred and four patients returned completed surveys (n = 104/164, 63% response rate). Overall satisfaction levels were high with most patients (n = 58/100, 58%; no answer provided (NAP), n = 4) equally satisfied or nearly equally satisfied with VC in comparison to a usual clinic encounter. The majority of patients felt that there should be a role for VC in the future (n = 84/102, 82%; NAP, n = 2). The majority of patients (n = 61/99, 61%; NAP, n = 5) were very relieved to avoid a hospital visit due to perceived risk of potential exposure to COVID-19. CONCLUSION: The majority of oncology patients were satisfied with a VC encounter. VC may have a role in the future of medical care in Ireland post the COVID-19 pandemic.

RESUMO

BACKGROUND: The prognostic role of thyroid transcription factor-1 (TTF-1) expression in lung cancer has been assessed but with inconsistent results. The present study aimed to evaluate the prognostic value of TTF1 expression in advanced non-squamous non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: In this retrospective study, patients with stage IIIB-IV non-squamous NSCLC were enrolled. Progression free survival (PFS) and overall survival (OS) were assessed according to TTF1 expression status, age categories (≤60 vs >60 years), gender, performance status (PS) (0-2 vs 3-4), type of 1st line chemotherapy (pemetrexed containing vs others) and EGFR status. RESULTS: A total of 120 patients were included. In univariate analysis, PFS was improved in patients with PS 0-2 (7.0 vs 2.0 months, p=0.002) and those who received pemetrexed-containing chemotherapy (9.2 vs 5.8 months, p=0.004). OS was improved in female patients (23.0 vs 8.7 months, p<0.0001), PS 0-2 (14.4 vs 2.0 months, p<0.0001), those with pemetrexed-containing chemotherapy (17.0 vs 11.0 months, p=0.019), TTF1-positive (12.8 vs 5.8 months, p=0.011) and EGFR- mutant patients (23.0 vs 11.7 months, p=0.006). In multivariate analysis, male gender (HR=2.34, p=0.025) and non-pemetrexed containing therapy (HR=2.24, p=0.022) were independent predictors of worse PFS. Wild EGFR status (HR=2.49, p=0.015) and male gender (HR=2.78, p=0.008) were predictors of worse OS. CONCLUSIONS: Pemetrexed-containing therapy significantly improved PFS while OS was improved in EGFR mutant patients. Female patients had better PFS and OS. TTF1 expression was not a prognostic marker in advanced non-squamous NSCLC.
