PLA2G7/PAF-AH as Potential Negative Regulator of the Wnt Signaling Pathway Mediates Protective Effects in BRCA1 Mutant Breast Cancer. Int J Mol Sci 2023; 24:ijms24010882. [PMID: 36614323 PMCID: PMC9821466 DOI: 10.3390/ijms24010882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 12/23/2022] [Accepted: 12/29/2022] [Indexed: 01/05/2023] Open
Abstract
Past studies have confirmed that aberrant activation of the Wnt/β-catenin signaling is associated with tumorigenesis and metastasis in breast cancer, while the role of platelet-activating factor acetylhydrolase (PLA2G7/PAF-AH) in this signaling pathway remains unclear. In this study, we analyze the functional impact of PAF-AH on BRCA1 mutant breast cancer and explore its relationship to the Wnt signaling pathway. By performing immunohistochemistry, PAF-AH expression and β-catenin expression were examined in both BRCA1 WT and BRCA1 mutant breast cancer specimens. The BRCA1 mutant breast cancer cell line HCC1937 was used for in vitro experiments to assess the impact of PAF-AH on cellular functions. The intracellular distribution of β-catenin depending on PLA2G7/PAF-AH expression was investigated by immunocytochemistry. Significantly higher nuclear expression levels of PAF-AH were found in BRCA1 mutant tissue specimens than in BRCA1 WT samples. Cell viability, proliferation, and the motility rate of HCC1937 were significantly enhanced after PLA2G7 silencing, which indicated a protective role of PAF-AH in breast cancer. Nuclear PAF-AH expressed correlatedly with membranous β-catenin. PLA2G7 silencing provoked the β-catenin translocation from the membrane to the nucleus and activated Wnt signaling downstream genes. Our data showed a protective effect of high PAF-AH expression in BRCA1 mutant breast cancer. PAF-AH may achieve its protective effect by negatively regulating the Wnt pathway. In conclusion, our research sheds new light on the regulatory pathways in BRCA1 mutant breast cancer.

MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58010112. [PMID: 35056420 PMCID: PMC8780999 DOI: 10.3390/medicina58010112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 01/05/2022] [Accepted: 01/06/2022] [Indexed: 11/16/2022]
Abstract
Background and objectives: In the treatment of the special type of breast cancer (STBC), the choice of chemotherapeutic agents is often based on the characteristic features of the histological type. On the other hand, the surgical strategy is usually determined by the tumor size and presence of lymph node metastasis, and the indication for immediate reconstruction is rarely discussed based on the histological type. The prognoses of STBC and invasive ductal carcinoma of the breast (IDC) patients who underwent subcutaneous mastectomy (SCM) with immediate reconstruction at our institution were compared. Materials and Methods: A total of 254 patients with SCM with immediate reconstruction from 1998 to 2018 were included; their tumor diameter or induration was less than 25 mm, and it was not in close proximity to the skin. Preoperative chemotherapy and non-invasive cancer cases were excluded. Results: The number of patients was 166 for skin-sparing mastectomy (SSM) and 88 for nipple-sparing mastectomy (NSM). The reconstructive techniques were deep inferior epigastric artery perforator flap (DIEP) reconstruction in 43 cases, latissimus dorsi flap reconstruction (LDflap) in 63 cases, tissue expander (TE) in 117 cases, and transverse rectus abdominis myocutaneous flap/vertical rectus abdominis myocutaneous flap (TRAM/VRAM) reconstruction in 31 cases. The histological types of breast cancer were 211 IDC and 43 STBC; 17 were mucinous carcinoma (MUC), 17 were invasive lobular carcinoma (ILC), 6 were apocrine carcinoma, 1 was tubular carcinoma, and 2 were invasive micropapillary carcinoma. There was no difference in local recurrence or disease-free survival (LRFS, DFS) between IDC and STBC, and overall survival (OS) was significantly longer in STBC. OS was better in the STBC group because SCM with immediate reconstruction was performed for STBC, which is a histological type with a relatively good prognosis. Highly malignant histological types, such as squamous cell carcinoma or metaplastic carcinoma, were totally absent in this study. Conclusions: The indications for SCM with immediate reconstruction for relatively common STBCs such as MUC and ILC can be the same as for IDC.

Abstract
Background The aim of this study was to investigate the role of axillary lymph node dissection on the outcome of patients with tubular carcinoma of the breast. Material/Methods Patients diagnosed with tubular carcinoma of the breast between 2000–2013 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Statistical analysis of the data was undertaken, including analysis of breast cancer-specific survival (BCSS). Results Of the 5,645 patients identified on the SEER database with tubular carcinoma of the breast, 5,032 (89.4%) patients had undergone axillary lymph node dissection, with significantly increased rates after 2002 compared with rates between 2000–2001 (p <0.001), which stabilized between 2002–2013 (p=0.330). Axillary lymph node metastases were present in 6.1% of all patients and in 5.3% of patients with a tumor size ≤2 cm. Lymph node-positive disease was associated with patient age ≤65 years, intermediate-grade or high-grade tumors, and tumor size >2.0 cm. Axillary lymph node dissection was an independent prognostic indicator. The 10-year BCSS was 97.3% and 96.6% in patients with and without axillary lymph node dissection, respectively (p=0.002). The number of removed lymph nodes was not related to breast cancer-specific survival. Conclusions In patients with tubular carcinoma of the breast, lymph node status was not associated with significant breast cancer-specific survival. However, axillary lymph node dissection may still be considered for patients with for tubular carcinoma of the breast even in patients with a small tumor size.

Abstract
Background The value of postoperative radiotherapy in tubular breast carcinoma patients under 65 years is uncertain. Methods Data on patients with estrogen receptor positive T1N0M0 tubular breast carcinoma who were younger than 65 years and who received breast-conserving surgery between 2000 and 2013 were retrieved from the Surveillance, Epidemiology and End Results database. Demographic, clinicopathologic features, and receipt of postoperative radiotherapy were analyzed to investigate effects on survival. Results Data from 2442 patients were analyzed, of whom 2020 (82.7%) received postoperative radiotherapy and 422 (17.3%) did not. The number of patients treated with or without postoperative radiotherapy showed no differences during the study period (p = 0.184). Radiotherapy was more likely to be administered in patients with well differentiated tumors. Multivariate Cox analysis showed that postoperative radiotherapy delivery was significantly correlated with better breast cancer-specific survival (BCSS) (hazard ratio [HR] 0.297, 95% confidence interval [CI] 0.105–0.836, p = 0.022) and overall survival (OS) (HR 0.656, 95% CI 0.441–0.978, p = 0.038). Ten 10-year BCSS was 99.3% in patients who received postoperative radiotherapy and 98.1% in those who did not (p = 0.020), and 10-year OS was 93.4 and 91.0%, respectively (p = 0.029). Postoperative radiotherapy increased BCSS and OS in the subgroups of age < 50 years, non-Hispanic white, well differentiated tumors, and progesterone receptor positive tumors. Conclusions Postoperative radiotherapy after breast-conserving surgery improved survival outcomes in tubular breast carcinoma patients aged < 50 years. However, omitting postoperative radiotherapy may not decrease survival in patients aged ≥50 years.

Abstract
Introduction We aimed to evaluate the clinicopathologic characteristics and clinical outcomes of the mixed type versus the pure type of tubular carcinoma (TC) of the breast in a retrospective cohort study. Materials and methods Patients were categorized into the following three groups: patients with pure TC of the breast (the PTC group), patients with TC and carcinoma in situ of the breast (the TC-CIS group), and patients with TC and other invasive carcinomas of the breast (the TC-IC group). We compared the clinicopathologic characteristics and treatment outcomes of the three groups. The primary end point of this study was breast cancer-specific survival (BCSS). Secondary end points included distant metastasis-free survival (DMFS) and locoregional recurrence (LRR). Results A total of 68 patients were included in this study, including 31 patients in the PTC group, 12 in the TC-CIS group, and 25 in the TC-IC group. Our data showed that PTC and TC-CIS were more likely to be smaller in size (P=0.014) and had substantially less nodal involvement (P=0.019), compared with TC-IC. The median follow-up time was 64.3 months (range, 3.78–223.2 months) for all patients. No locoregional relapse was observed in any group during the follow-up period. The 10-year BCSS of the PTC, TC-CIS, and TC-IC groups was 100%, 100%, and 95.2%, respectively, and the 10-year DMFS was 92.3%, 100%, and 96.0%, respectively. There was no significant difference in terms of BCSS (P=0.53) or DMFS (P=0.84) between the three groups. Conclusion This study indicates that both the pure type and mixed type of TC of the breast show very low LRR and distant metastasis rate and have excellent survival. The TC-IC group is likely to show good prognosis similar to the PTC group. Further clinical trials with larger sample sizes as well as molecular and genetic studies are warranted.

Abstract
AIM We explored the clinicopathologic characteristics, prognostic factors and outcomes in tubular carcinoma (TC) of the breast. METHODS We retrospectively assessed 8091 TC patients using the SEER database from 2000 to 2013. RESULTS Most patients were non-Hispanic white, well-differentiated disease, tumor size ≤2 cm, node-negative, nonmetastatic, hormone receptor-positive and HER2-negative status. The 10-year breast cancer-specific survival and overall survival were 98.1 and 82.0%, respectively. Multivariate analysis indicated that age, ethnicity, surgery procedures, radiotherapy and chemotherapy were independent predictors affecting survival outcomes. There was comparable breast cancer-specific survival between surgery and nonsurgery groups. CONCLUSION The patients with TC has excellent survival outcomes, which may in part be due to the favorable tumor characteristics.

Abstract
Introduction To investigate the temporal trends of postoperative radiotherapy (RT) administration and the effects of omitting postoperative RT on breast cancer-specific survival (BCSS) in women aged ≥65 years with tubular carcinoma (TC) of the breast who received breast-conserving surgery (BCS). Methods We included women aged ≥65 years with non-metastatic TC of the breast who underwent BCS between 2000 and 2013 using the Surveillance, Epidemiology, and End Results database. Statistical analyses were performed using chi-square tests, Kaplan–Meier analyses, Cox proportional hazards models, and a 1:1 propensity score matching (PSM). Results Before PSM, a total of 1,475 patients with tumor size ≤2 cm, node-negative disease, and estrogen receptor-positive disease were identified, including 927 (62.8%) underwent postoperative RT and 548 (37.2%) had postoperative omission of RT. The administration of postoperative RT steadily declined over the study period. Patients with younger age, larger tumor size, and other race/ethnicity were more likely to receive postoperative RT. The median follow-up duration was 85.0 months, the 5- and 10-year BCSS rates were 98.7 and 97.9%, respectively. The median BCSS was 161.9 and 165.0 months for patients with and without postoperative RT, respectively, and the corresponding 5-year BCSS rates were 98.5 and 98.8%, respectively (p = 0.134). Prognostic analysis indicated that postoperative RT was not associated with improved BCSS rates compared with RT omission (p = 0.134). After PSM, a total of 431 complete pairs were generated. In the matched population, the 5-year BCSS rates were 98.6 and 98.4% in non-postoperative RT and postoperative RT groups, respectively (p = 0.858). The univariate analyses also confirmed that the administration of postoperative RT was not associated with better BCSS (p = 0.858). Conclusion The incidence of breast cancer-related death is probably sufficiently low to avoid postoperative RT in women aged ≥65 years with TC of the breast after BCS.

Abstract
Objective We retrospectively analyzed the magnetic resonance (MR) imaging features and diffusion-weighted imaging findings of the 12 masses of 10 patients with tubular carcinoma (TC), including mammography and sonography findings. Materials and Methods Mammographic, sonographic and magnetic resonance imaging features in 12 histopathologically confirmed masses diagnosed as TC of the breast within 10 patients were evaluated. Morphologic characteristics, enhancement features, apparent diffusion coefficient (ADC) values were reviewed. Results On mammography (n=5), TC appeared as high density masses with indistinct, spiculated or obscured margins. Sonographically, TC appeared as a hypoechoic appearance (n=12) with posterior acoustic shadowing in nine. On MR imaging, the margins of ten of twelve masses were irregular. Internal enhancement patterns were heterogeneous in 10 patients. Dynamic enhancement patterns illustrated plateau kinetics (n=8). On the T2-weighted images 4 masses were hypointense, and 8 were hyperintense; hypointense internal septation was found in seven of these. Tubular carcinoma appeared as hyperintense on diffusion-weighted imaging with ADC values of 0.85±0.16×10-3 mm2/s that was lower than the normal parenchyma of 1.25±0.25×10-3 mm2/s. Conclusion According to our study with a limited number of cases, tubular carcinomas can be described as hyperintense breast carcinomas with or without dark internal septation like appearance on T2-weighted images. Low ADC values from DW imaging can be used to differentiate TC from hyperintense benign breast lesions.

Tubular carcinoma of the breast: clinicopathologic features and survival outcome compared with ductal carcinoma in situ. J Breast Cancer 2013; 16:404-9. [PMID: 24454462 PMCID: PMC3893342 DOI: 10.4048/jbc.2013.16.4.404] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2013] [Accepted: 10/19/2013] [Indexed: 11/30/2022] Open
Abstract
Purpose Tubular carcinoma (TC) of the breast is an uncommon histological subtype of invasive breast cancer with an excellent prognosis compared with standard invasive ductal carcinoma. Recent studies suggested a possible precursor role for low grade ductal carcinoma in situ (DCIS) in the development of TC. The goal of this analysis was to understand the clinicopathologic features and outcomes of TC by comparing TC with DCIS. Methods A retrospective review identified 70 patients with TC and 1,106 patients with DCIS between 1995 and 2011. Student t-test and Fisher exact test were used to compare the clinicopathologic characteristics of TC patients with those of DCIS patients. The Kaplan-Meier method and Cox regression analysis were used to determine disease-free survival (DFS) rates. Results Compared to DCIS, TC exhibited favorable clinicopathologic characteristics such as a lower nuclear grade (92.3%), higher expression of hormonal receptors (estrogen receptor-positive, 92.9%; progesterone receptor-positive, 87.0%), and less frequent overexpression of human epidermal growth receptor 2 (12.9%). DFS did not differ significantly between the TC and DCIS groups (5-year DFS, 100% vs. 96.7%; 10-year DFS, 92.3% vs. 93.3%; p=0.324), and cancer-specific deaths were not noted in either group. However, axillary lymph node involvement was observed in six (8.6%) of the 70 patients with TC. Three of these patients had small tumors (≤1 cm). Conclusion In our study cohort, TC was associated with an excellent prognosis and a low rate of lymph node metastasis. However, lymph nodes metastases were found even in patients with small tumors (≤1 cm). Axillary staging must be considered for all patients with TC of the breast.

Abstract
Aims and background Often neglected by large clinical trials, patients with uncommon breast malignancies have been rarely analyzed in large series. Patients and methods Of 2,052 patients diagnosed with breast cancer and followed in our Institution from January 1985 to December 2009, we retrospectively collected data on those with uncommon histotypes, with the aim of investigating their presentation characteristics and treatment outcome. Results Rare histotypes were identified in 146 patients (7.1% of our total breast cancer population), being classified as follows: tubular carcinoma in 75 (51.4%), mucinous carcinoma in 36 (24.7%), medullary carcinoma in 25 (17.1%) and papillary carcinoma in 10 patients (6.8%). Whereas age at diagnosis was not significantly different among the diverse diagnostic groups, patients with medullary and papillary subtypes had a higher rate of lymph node involvement, similar to that of invasive ductal carcinoma. Early stage diagnosis was frequent, except for medullary carcinoma. Overall, in comparison with our invasive ductal carcinoma patients, those with rare histotypes showed a significantly lower risk of recurrence, with a hazard ratio of 0.28 (95% CI, 0.12–0.62; P = 0.002). Conclusions According to our analysis, patients with uncommon breast malignancies are often diagnosed at an early stage, resulting in a good prognosis with standard treatment.

Abstract
PURPOSE Pure tubular carcinoma of the breast (PTCB) represents a distinct subtype of invasive ductal carcinoma (IDC) that is generally thought to be associated with better prognosis than even low-grade IDC. There has been controversy as to the role of adjuvant radiation therapy (RT) in this population. We hypothesized that adjuvant RT would demonstrate a survival improvement. METHODS AND MATERIALS We queried the Surveillance, Epidemiology and End Results database for the years 1992-2007 to identify patients with pure tubular carcinomas of the breast. Patient demographics, tumor characteristics, and surgical and RT treatments were collected. Survival analysis was performed using the Kaplan-Meier method for univariate comparisons and Cox proportional hazards modeling for multivariate comparisons, stratifying on the basis of age with a cutoff age of 65. RESULTS A total of 6465 patients were identified: 3624 (56.1%) patients underwent lumpectomy with RT (LUMP+RT), 1525 (23.6%) patients underwent lumpectomy alone (LUMP), 1266 (19.6%) patients received mastectomy alone (MAST), and 50 (0.8%) patients underwent mastectomy with RT (MAST+RT). When we compared the LUMP+RT and LUMP groups directly, those receiving adjuvant RT tended to be younger and were less likely to be hormone receptor-positive. Overall survival was 95% for LUMP+RT and 90% for LUMP patients at 5 years. For those 65 or younger, the absolute overall survival benefit of LUMP+RT over LUMP was 1% at 5 years and 3% at 10 years. On stratified multivariate analysis, adjuvant RT remained a significant predictor in both age groups (P=.003 in age ≤ 65 and P=.04 in age >65 patients). Other significant unfavorable factors were older age and higher T stage (age >65 only). CONCLUSIONS Since sufficiently powered large scale clinical trials are unlikely, we would recommend that adjuvant radiation be considered in PTCB patients age 65 or younger, although consideration of the small absolute survival benefit is important. Adjuvant radiation can be omitted for patients older than 65.

Abstract
To date, there are no standard guidelines for treating patients with ipsilateral breast tumor recurrence (IBTR). Current practice is to resect the recurrence with a radical intent followed possibly by radiotherapy if the patient has not received this before, but the role of further adjuvant medical (hormone or chemotherapy) therapy remains undefined. Currently Phase III trials are underway to answer this question. In this review, we will focus on published data relating to IBTR and discuss recent trials. The results from the Phase III trials will not be available for sometime. At the time of IBTR, it is reasonable to change the endocrine therapy with indirect evidence from sequencing of impact on outcome. There is currently no conclusive evidence to suggest that further adjuvant chemotherapy post loco-regional recurrence impacts on survival, though the use of noncross-resistant chemotherapy drugs may make sense in those at highest risk. Biopsy at IBTR is helpful to distinguish whether it is a true recurrence or a new primary tumor and receptor phenotyping may be helpful for HER2. Future trials in IBTR need to address the following issues: to be able to distinguish between true recurrence and new primary (consensus required on definitions); pathologic processing relating to margins needs to be standardized (1 or 5 mm wide specimens); documentation of the pattern of IBTR in relation to each histopathologic subtype and methods used for pathologic examination by centers. Regional nodal recurrence including supraclavicular node recurrence is not dealt with in this review.

Abstract
Tubular breast carcinoma is a highly differentiated carcinoma with an excellent prognosis. Distinct genetic alterations in tubular breast carcinoma cells have been described, especially broad genetic losses on the q-arm of chromosome 16. These are more common in lobular breast carcinoma and low-grade ductal carcinoma in situ than in ductal breast carcinoma and high-grade ductal carcinoma in situ. To further delineate the molecular changes involved in tubular breast carcinoma more precisely, we examined 23 formalin-fixed and paraffin wax-embedded tissue samples (21 of tubular breast carcinoma and 2 of nonneoplastic breast epithelium) by microarray-based comparative genomic hybridization focusing on 287 genomic target clones of oncogenes and tumor suppressor genes. The results obtained from all nonneoplastic tissue samples of breast epithelium indicate no DNA copy number changes. In the tubular breast carcinoma samples, the highest frequencies for DNA sequence copy number losses were detected for CDH13 (in 86% of the samples) and MSH2, KCNK12 (in 52% of the samples). The highest frequencies of DNA sequence copy number gains were detected for HRAS and D13S319XYZ (each in 62% of the samples). Using principal component analysis, 3 subgroups of tubular breast carcinomas showing relative genetic changes were identified. For validation, the most frequent DNA copy number loss for CDH13 (18/21) was confirmed using fluorescence in situ hybridization in 4 of 5 tubular breast carcinomas analyzed. The newly identified genes with considerable copy number changes may include so far unknown candidate genes for the development and progression of tubular breast carcinoma, such as CDH13. The study provides the starting point for further delineating their detailed influence on the pathogenesis of tubular breast carcinoma.

Abstract
Invasive ductal carcinoma and ductal carcinoma in situ account for about 85% of breast cancers. Unusual breast neoplasms may be broadly divided into invasive lobular carcinoma, well-differentiated subtypes of invasive ductal carcinoma, cancers of stromal origin, and metastatic neoplasms. Clues are often present in imaging characteristics, patient demographics, and/or clinical features that may suggest that the finding is not the usual type of breast cancer. Some rare malignancies also provide specific clues to their diagnosis. This review provides an overview of unusual and a few rare malignant breast neoplasms, highlighting particular or specific clinical or imaging findings that will enable residents to expand their differential diagnosis of breast lesions beyond invasive ductal carcinoma.

Abstract
PURPOSE The effectiveness of radiation therapy (RT) in reducing local recurrence after breast-conserving surgery (BCS) in unselected patients with early stage invasive breast cancer has been demonstrated in multiple randomized trials. Whether a subset of women can achieve local control without RT is unknown. In 1986, we initiated a prospective one-arm trial of BCS alone for highly selected breast-cancer patients. This report updates those results. METHODS AND MATERIALS Eighty-seven (of 90 planned) patients enrolled from 1986 until closure in 1992, when a predefined stopping boundary was crossed. Patients were required to have a unicentric, T1, pathologic node-negative invasive ductal, mucinous, or tubular carcinoma without an extensive intraductal component or lymphatic-vessel invasion. Surgery included local excision with margins of at least 1 cm or a negative re-excision. No RT or systemic therapy was given. RESULTS Results are available on 81 patients (median follow-up, 86 months). Nineteen patients (23%) had local recurrence (LR) as a first site of failure (average annual LR: 3.5 per 100 patient-years of follow-up). Other sites of first failure included 1 ipsilateral axilla, 2 contralateral breast cancers, and 4 distant metastases. Six patients developed other (nonbreast) malignancies. Nine patients have died, 4 of metastatic breast cancer and 5 of unrelated causes. CONCLUSIONS Even in this highly selected cohort, a substantial risk of local recurrence occurred after BCS alone with margins of 1.0 cm or more. These results suggest that with the possible exception of elderly women with comorbid conditions, radiation therapy after BCS remains standard treatment.

Abstract
AIMS We aimed to evaluate the prevalence of and the risk factors for axillary lymph-node metastases in pure tubular carcinoma (PTC) of the breast. The role of axillary staging and treatment in PTC was also evaluated. METHODS Between March 2001 and August 2004, 33 PTC patients underwent sentinel node (SN) biopsy as a part of their surgical treatment. Level I/II axillary clearance was carried out in case of tumour positive SN findings. To confirm the correct histological diagnosis (PTC, >90% tubular component), the breast tumours were reviewed by an expert breast pathologist. RESULTS The SN were successfully harvested in all patients. The median number of SN harvested in the axilla was 3 (range 1-10). Nine (27%) of the 33 patients had axillary nodal metastases. The median number of metastatic nodes was 1 (range 1-3). The median size of the SN metastases was 0.5 mm (mean 1.7 mm, range 0.4-5 mm). In six patients, micrometastases were the only tumour positive SN findings. The median histological tumour size was similar, 9 vs 10mm, in patients with or without axillary metastases. The median patient age was 54 (range 44-71) and 57 (range 39-80) years, respectively. After the histopathological review, six of the 27 patients with true PTC had axillary metastases. The review did not significantly change the risk factors for axillary metastases. CONCLUSIONS Every fourth PTC patient has axillary lymph-node metastases, most often micrometastases. SN biopsy appears as a feasible method for axillary staging in PTC patients.

Abstract
A solid breast mass that decreases in size over time without treatment is generally felt to be inconsistent with a diagnosis of malignancy. We describe a case where this dogma proves to be incorrect. Mammographic features of a mass, along with the patient's clinical hormonal status, need to be considered along with size characteristics.

Abstract
BACKGROUND The favorable prognosis associated with tubular carcinoma of the breast has led some studies to propose less aggressive treatments for patients with this disease. This study aims to address the extent of therapy needed for tubular patients. METHODS A retrospective review identified 73 cases of tubular carcinoma treated at the Massachusetts General Hospital between 1980 and 2002. Primary treatment was conservative surgery (CS) plus radiation therapy (RT) in 67%, CS without RT in 18%, and mastectomy in 15%. Median follow-up time was 90.5 months. The published literature of 529 conservatively treated tubular carcinomas was reviewed along with the 62 conservative cases from this series. : No patients developed distant metastasis or died from this disease. Local failure occurred in three (4%) of the cases, after 13, 84 and 121 months. All three had initially been treated with CS + RT. Five cases were node-positive, three of which were associated with a primary tumor smaller than 1 cm. Thirteen women, with a median age of 74, were treated by CS without RT and none recurred. A literature review showed that adjuvant RT reduces local failure following CS for tubular carcinoma. CONCLUSIONS Tubular carcinoma is associated with an excellent prognosis, but long-term follow-up is essential for detecting local failures and a small primary tumor size does not preclude nodal involvement. Adjuvant RT reduces the incidence of local failure following CS for tubular carcinoma, however, elderly women treated by CS may have a very low risk of local recurrence without adjuvant RT.
