AbstractThe management of metaplastic breast carcinoma (MBC) has largely paralleled the paradigms used for invasive ductal carcinoma (IDC) in the current National Comprehensive Cancer Network guidelines of breast cancer. However, patients with IDC and MBC have been shown to have a different prognosis, and there are significant differences in risk and failure patterns after treatment. The purpose of this study was to compare breast cancer specific survival (BCSS) and hazard function between IDC and MBC. We included patients from the Surveillance, Epidemiology, and End Results program with stage I-III IDC and MBC between 2000 and 2012. Statistical analyses were including chi-square analysis, life-table methods, multivariate Cox proportional hazards models, and propensity score matching (PSM). We identified 294,719 patients; 293,199 patients with IDC and 1520 patients with MBC. Multivariate analyses showed that the MBC subtype had significantly lower BCSS than the IDC subtype before and after PSM (p < 0.001). There were significant differences in the hazard curve between IDC and MBC. The hazard curve for breast cancer mortality in the IDC cohort peaked at 3 years (2%), and then changed to a slowly decreasing plateau after prolonged follow up. However, the hazard curve for breast cancer mortality in the MBC cohort peaked at 2 years (7%), then declined sharply between 3 and 6 years, and changed to a low death rate after a follow-up time exceeding 6 years. Subgroup analyses revealed that the hazard curves significantly differed between IDC and MBC after stratifying by tumor stage and hormone receptor status. Our study suggests that patients with MBC should receive more effective systemic agents and intensive follow-up because of their significantly augmented risk of death compared to IDC patients.

Purpose There are more than 2,000,000 breast cancer survivors in the United States today. While surveillance for asymptomatic recurrence and second primary is included in consensus recommendations, the effectiveness of this surveillance has not been well characterized. Our purpose is to estimate the effectiveness of surveillance mammography in a cohort of breast cancer survivors with complete ascertainment of surveillance mammograms and negligible losses to follow-up. Patients and Methods We enrolled 1,846 stage I and II breast cancer patients who were at least 65 years old at six integrated health care delivery systems. We used medical record review and existing databases to ascertain patient, tumor, and therapy characteristics, as well as receipt of surveillance mammograms. We linked personal identifiers to the National Death Index to ascertain date and cause of death. We matched four controls to each breast cancer decedent to estimate the association between receipt of surveillance mammogram and breast cancer mortality. Results One hundred seventy-eight women died of breast cancer during 5 years of follow-up. Each additional surveillance mammogram was associated with a 0.69-fold decrease in the odds of breast cancer mortality (95% CI, 0.52 to 0.92). The protective association was strongest among women with stage I disease, those who received mastectomy, and those in the oldest age group. Conclusion Given existing recommendations for post-therapy surveillance, trials to compare surveillance with no surveillance are unlikely. This large observational study provides support for the recommendations, suggesting that receipt of surveillance mammograms reduces the rate of breast cancer mortality in older patients diagnosed with early-stage disease.

Invasive ductal carcinoma (IDC) is the most common histopathological type of breast cancer, accounting for up to 85% of all invasive breast carcinomas [1]. It spreads usually to the bone first. Solitary metastasis is commonly located in the lung, liver or brain [2]. Adrenal glands locations are extremely rare [3]. We report a case of isolated metachronous right adrenal metastasis, diagnosed four years after breast IDC management. The aim is to highlight clinical, diagnostic and therapeutic characteristics of this entity.

BACKGROUND: Metaplastic breast carcinoma (MBC) is a rare type of breast cancer (0.20–1.00% of all cases). With a more aggressive clinical course, MBC frequently presents as a triple-negative subtype. OBJECTIVE: To describe a case series, analyzing patients survival in four MBC cases. METHODS: The cases were obtained from 532 medical records of breast cancer patients (0.7% of the total). RESULTS: All patients were female. Mean patient age was 49 years (range: 38–60 years). Mean tumor size was 8.9 cm (range: 3.0–15.5 cm). Mastectomy was performed in three cases. One patient had axillary nodal metastasis. All underwent chemotherapy and three received radiation therapy after surgery. CONCLUSIONS: With a mean follow-up of 36 months (range: 10–60 months), one case had a tumor recurrence (25%). Three patients (75%) died from metastatic disease and one (25%) is still alive and free of disease.

140 Background: Metaplastic breast carcinoma (MBC) is a rare subtype that accounts for <1% of all breast carcinomas. MBC is frequently triple-negative and neoadjuvant chemotherapy (NAC) is often used in triple-negative breast cancer (TNBC). The objective of this analysis is to ascertain response rates of MBC to NAC as compared to non-metaplastic TNBC. Methods: We searched the Magee Women’s Cancer Center of UPMC IRB-approved neo-adjuvant treatment database which contains outcome data on 594 patients treated from 2004-2010. 116 patients with triple negative breast cancer (ER /PR negative or ER /PR weakly positive [H score of 10 or less] and HER2 negative or indeterminate [HER2 1+ or 2+ without amplification by FISH]), were identified. Nine of these TNBCs had metaplastic subtype and two groups were analyzed: metaplastic breast carcinoma (MBC) (N= 9) and non-metaplastic breast carcinoma (NMBC) (N = 107). Tumor volume reduction (TVR), pathologic complete response (pCR), recurrence and mortality were compared in both groups. Results: Average follow-up in MBC group was 43 months and no patients were lost to follow-up. Average tumor size on presentation in MBC group was 4.47 cm while in NMBC group it was 3.33 cm. pCR was noted in 0/9 MBC and 43/107 NMBC cases (p = 0.0253). 6/9 patients had mastectomy, 2/9 had breast conserving surgery (BCS) and 1/9 patients did not have a surgery yet. Average TVR was 28% in MBC cases compared to 74% in NMBCs when cases with pCR were included (p = 0.0001) and 56% when cases with pCR were excluded (p = 0.0202). Follow up on 9 MBC cases revealed 1 recurrence and subsequent death (11%). Follow-up on 64 NMBC patients who failed to achieve pCR revealed 22 recurrences (34%) and 18 of them subsequently died (28%). Follow-up on 43 NMBC cases that achieved pCR revealed 3 recurrences (7%) and 1 death (2%). Conclusions: MBC was characterized by larger size at baseline as compared to NMBC. There were no pCR’s seen in MBC, but some MBC did achieve response that allowed for breast conservation. Although the average tumor volume reduction was significantly less in MBC compared to NMBC, the NMBC that failed to achieve pCR fared much worse than MBC who did not achieve pCR. Therefore, the triple-negative paradox is likely not applicable to MBC.

Objectives: To analyze prospectively the association between hormone replacement therapy (HRT) and mortality in women before old age. Design and methods: A group of 11 667 women (91% of the age cohort of the area) aged 52–62 years from the population-based Kuopio Osteoporosis Risk Factor and Prevention Study were followed for 7 years in 1994–2001. Information about HRT use and health events was obtained from two repeated questionnaires in 1989 and 1994. Information about deaths and causes of death from the follow-up period was obtained from the Statistics Finland. Cox’s proportional-hazards models were used to calculate risk of death related to the use of HRT. Results: At the start of follow-up, 2203 women had used HRT >5 years, 3945 women ≤5 years and 5519 women had never used it. During the follow-up, 361 deaths occurred. Compared with non-users of HRT, the adjusted hazard ratio (HR) of death from any cause was 1.05 (95% confidence interval (CI) 0.80–1.36) in women who used HRT ≤5 years and 1.06 (95% CI 0.78–1.46) in women who used HRT >5 years. The adjusted HR for coronary heart disease (CHD) mortality in women who used HRT ≤5 years was 0.79 (95% CI 0.36–1.73), and in women who used HRT >5 years, 2.16 (95% CI 0.93–4.98). For breast cancer mortality the adjusted HR for ≤5 years of HRT use was 0.96 (95% CI 0.32–2.82) and 2.62 (95% CI 0.98–7.00) for >5 years of HRT use. Conclusions: History of HRT use does not affect overall or CHD mortality in women. More than 5 years of HRT use may increase the risk of breast cancer mortality.

Annual breast magnetic resonance imaging (MRI) plus mammography is the standard of care for screening women with inherited BRCA1/2 mutations. However, long-term breast cancer-related mortality with screening is unknown. Between 1997 and June 2011, 489 previously unaffected BRCA1/2 mutation carriers aged 25 to 65 years were screened with annual MRI plus mammography on our study. Thereafter, participants were eligible to continue MRI screening through the high-risk Ontario Breast Screening Program. In 2019, our data were linked to the Ontario Cancer Registry of Cancer Care Ontario to identify all incident cancers, vital status and causes of death. Observed breast cancer mortality was compared to expected mortality for age-matched women in the general population. There were 91 women diagnosed with breast cancer (72 invasive and 19 ductal carcinoma in situ (DCIS)) with median follow-up 7.4 (range: 0.1 to 19.2) years. Four deaths from breast cancer were observed, compared to 2.0 deaths expected (standardized mortality ratio (SMR) 2.0, p = 0.14). For the 489 women in the study, the probability of not dying of breast cancer at 20 years from the date of the first MRI was 98.2%. Annual screening with MRI plus mammography is a reasonable option for women who decline or defer risk-reducing mastectomy.
