Metaplastic Breast Carcinoma

Synchronous primary cancers occur in 1.7% of breast cancer cases and metaplastic breast cancer (MBC) occurs in less than 1% of breast cancer cases. We present a previously healthy 66-year-old woman diagnosed with MBC after surgical resection of a presumed cyst. A second primary cancer, multifocal lung adenocarcinoma, was discovered during the staging process for her MBC. Remarkably she had not experienced pulmonary or constitutional symptoms at the time of diagnosis. She received chemotherapy with paclitaxel and carboplatin, followed by immunotherapy with nivolumab. At 24 months of follow-up after her initial diagnosis, she was breast cancer-free with stable pulmonary nodules. This case highlights that rather than assuming multifocal lesions represent metastasis, biopsies should be considered as clinical management could be significantly altered in the presence of a synchronous cancer. Furthermore, platinum-based chemotherapy agents have potential to be considered in the treatment of MBC.

Metaplastic Breast Carcinoma

Metaplastic breast cancer is rare, representing < 5% of breast cancer (only eight cases have been reported so far). We present here a 42-year-old female complaining of a painless lump in the right breast for the previous two months. Physical examination revealed a palpable mass. Lumpectomy was performed and histopathologic examination revealed metaplastic breast carcinoma with foci of chondrosarcoma. The patient received adjuvant radiation therapy and chemotherapy and is currently following up as an outpatient. We also discuss diff erentimaging diagnostic features of this specifi c type of breast cancer using mammography, ultrasonography, and magnetic resonance imaging.

AbstractAimIndeterminate pulmonary nodules incidentally detected during radiological imaging completed for radiotherapy planning always creates dilemma for the oncologist. The purpose of this study is to evaluate the clinical significance of pulmonary nodules incidentally detected in patients undergoing locoregional radiotherapy for breast cancer and present a retrospective analysis of the natural progression of such nodules.MethodsA retrospective review of computed tomography scans of breast cancer patients who underwent radiotherapy over a period of 3 years to screen out patients with indeterminate lung nodules was undertaken. This was correlated with the patient and tumour characteristics and the status of the disease at last follow-up.ResultsOf the 132 patients reviewed 28 had indeterminate lung nodules. Of the 28 patients, four had progressive lung nodules on follow-up. Subgroup analyses did not show any significant correlation.Discussion and conclusionOne fifth of patients may present with incidentally detected lung nodules. Multiple nodules, ER negative status and locally advanced breast cancer may point to a higher risk of these nodules progressing to metastatic cancer. There is no indication to stop locoregional therapy in the presence of indeterminate nodules, but close follow-up of high-risk group is recommended.

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.

Metaplastic Breast Carcinoma

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.

e20641 Background: Chemotherapy induced alopecia (CIA) is a distressing adverse effect of many chemotherapy agents. The TC chemotherapy regimen (four cycles of docetaxel 75mg/m2 and cyclophosphamide 600mg/m2 given every 3 weeks apart) commonly used for aduvant therapy of breast cancer is associated with complete alopecia, with rare reports of permanent alopecia. Scalp cryotherapy has been reported to minimize or prevent CIA. Penguin cold caps are a commercially available scalp cooling product gaining increasing media attention. We conducted a prospective study aimed to assess efficacy of scalp cryotherpy in preventing CIA among women receiving adjuvant TC chemotherapy for early stage breast cancer who independently elected to use Penguin cold caps. Methods: Women at the Weill Cornell Breast Center who elected to use scalp cryotherapy with Penguin cold caps during adjuvant TC chemotherapy were asked to participate in the study. Degree of hair loss was rated by practitioner assessment using Dean’s alopecia scale (poor (>75% hair loss), moderate (50-75%), good (25-50%) or excellent (<25%)), by digital photographs, and by asking patients whether they felt a need to wear a wig or head covering due to hair loss. Assessments were made before each chemotherapy treatment and at a follow up visit between 3 weeks and 3 months after the completion of chemotherapy. Results: 17 patients have enrolled. 13 patients have completed chemotherapy. 2 patients currently undergoing chemotherapy and 2 patients who discontinued chemotherapy due to toxicity not related to alopecia are excluded from analysis. Dean’s alopecia scale score was excellent for 10 patients (77%) at every assessment. Dean’s score was good for 2 participants (15%) and moderate for 1 participant (8%) starting prior to fourth cycle of chemotherapy. Only 1 patient (8%) reported needing to wear a wig or head covering as a result of alopecia. Conclusions: Scalp cryotherapy using Penguin cold caps appears to be effective in preventing CIA among women undergoing chemotherapy with the TC regimen.

LBA500 Background: The primary endpoint of NSABP B-35, a phase III trial comparing 1 mg/day anastrozole to 20 mg/day tamoxifen, each given for 5 years, was breast cancer-free interval (BCFI), defined as the time from randomization to any breast cancer (BC) event including local, regional, or distant recurrence or contralateral disease, invasive or DCIS. Methods: Postmenopausal women with ER-receptor or PgR-receptor positive (by IHC analysis) DCIS and no invasive BC who had undergone a lumpectomy with clear resection margins were randomly assigned to receive either 20 mg/day tam or 1 mg/day A (blinded) for 5 years. Stratification was by age (<60 v ≥60). Results: From 1/6/2003 to 6/15/2006, 3,104 pts were entered and randomized (1552 in groups tam and A each). As of 2/28/15, follow-up information was available on 3,083 pts for OS and on 3,077 pts for all other disease-free endpoints, with mean time of follow-up of 8.6 years. There were 198 BCFI events, 114 in the tam group and 84 in the A group (HR, 0.73; p=0.03). 10-year point estimates for BCFI were 89.2% for tam and 93.5% for A. A significant time-by-treatment interaction (p=0.02) indicated that the effect was not evident until later in the study. There was a significant interaction between treatment and age group (p=0.04); benefit of A is only in women <60 years old. As to secondary endpoints, there were 495 DFS events, 260 in the tam group and 235 in the A group (HR, 0.89; p=0.21). 10-year point estimates for DFS were 77.9% for tam and 82.7% for A. There were 186 deaths, 88 in the tam group and 98 in the A group (HR, 1.11; p=0.48). 10-year point estimates for OS were 92.1% for tam, 92.5% for A. There were 8 deaths due to breast cancer in the tam group and 5 in the A group. There were 63 cases of invasive breast cancer in the tam group and 39 in the A group (HR, 0.61; p=0.02). There was a non-significant trend for a reduction in breast second primary cancers with A (HR, 0.68; p=0.07). Conclusions: Anastrozole provided a significant improvement compared to tamoxifen for BCFI, which was seen later in the study, primarily in women <60 years.

Metaplastic Breast Carcinoma

e12579 Background: Metaplastic breast carcinoma is a rare histological subtype that has basal like characteristics and is reported to have a poorer prognosis than no specific type/ductal carcinoma (ductal/NST). We aimed to investigate clinicopathological features and outcome from a single institution based registry. Methods: Clinical records of breast cancer patients treated during 2012-2019 were screened and 31 cases of metaplastic breast carcinoma were found. Descriptive analysis was done for patients’ demographics and clinicopathological features. Kaplan Meier method was used to assess survival outcomes. Results: The incidence of metaplastic breast cancer was 0.5% (31/6180) in our study out of which the most common histopathological differentiation was squamous (45.16%). The second most common was sarcomatoid histology (32.25%), followed by chondroid (9.68%) and mixed histology (12.9%). The median age at diagnosis was 60 years ranging from 28 to 82 years. 64.15% of patients were post-menopausal. At presentation, three (9.67%) patients had metastatic disease while the rest were diagnosed with early (51.61%) and locally advanced cancers (38.72%). Triple negative cancers (ER/PR/Her2 negative) constituted the vast majority with 22 cases (80.6%) while hormone receptor positive (ER/PR positive, Her-2 negative) and Her-2 neu positive (ER/PR negative) made up the rest with three patients (9.67%) each group respectively. The median overall survival was found to be 39 months (95% CI 25.46 - 52.53). Conclusions: After a thorough search in PubMed and Google Scholar, we could not find a larger case series from India with clinical outcomes for metaplastic breast carcinoma. Our results suggest that metaplastic breast carcinoma is a heterogenous disease. Outcomes of metaplastic breast carcinoma are relatively worse when compared with literature for triple negative breast cancer and breast cancer in general. Further biological understanding may offer valuable insights for newer targets and therapeutic approaches to metaplastic breast cancer.
