Occult breast cancer

Denise Thigpen, Amanda Kappler, Rachel Brem
Breast cancer is the second leading cause of cancer death in women. Estimates indicate a nearly 40% breast cancer mortality reduction when screening women annually starting at age 40. Although mammography is well known to be a powerful screening tool in the detection of early breast cancer, it is imperfect, particularly for women with dense breasts. In women with dense breast tissue, the sensitivity of mammography is reduced. Additionally, women with dense breasts have an increased risk of developing breast cancer while mammography has a lower sensitivity...

Background -Venous thromboembolism can be a presenting symptom of cancer, but the association between lower limb arterial thrombosis and cancer is unknown. We therefore examined cancer risk and prognosis of cancer in patients with lower limb arterial thrombosis. Methods -Using nationwide population-based Danish medical registries, we identified all patients diagnosed with first-time lower limb arterial thrombosis (1994-2013) and followed them until the occurrence of any subsequent cancer diagnosis, emigration, death, or 30 November 2013, whichever came first...

BACKGROUND: Contralateral risk-reducing mastectomy (CRRM) for breast cancer patients with BRCA mutations has been reported to not only reduce breast cancer incidence but also to improve survival. The National Comprehensive Cancer Network guidelines recommend providing CRRM to women with BRCA mutations who desire CRRM after risk-reduction counseling. However, in Japan, CRRM cannot be performed generally because it is not covered by health insurance. Thus, we conducted a feasibility study to confirm the safety of CRRM...

Introduction: Sentinel lymph node biopsy in prophylactic mastectomy is controversial. It avoids lymphadenectomy in occult carcinoma but is associated with increased morbidity. Women with BRCA mutations have a higher incidence of occult carcinoma and our objective was to assess the clinical utility of sentinel lymph node biopsy when these women undergo prophylactic mastectomy. Materials and Methods: Seven-year retrospective consecutive case-series study of women, with a BRCA deleterious mutation, admitted to prophylactic mastectomy, at our center...

BACKGROUND: Metastases to the thyroid gland are more frequent than previously thought, although most of them are occult or not clinically relevant. Overall, only 42 cases of metastases to thyroid from breast cancer have been reported thus far. Here we report the case of a patient with breast cancer metastatic to the thyroid. We also review the 42 previously reported cases (published between 1962 and 2012). This is the first review about metastases to thyroid gland from breast cancer. CASE PRESENTATION: A 64-year-old woman of Caucasian origin was diagnosed with a lobular invasive carcinoma of the breast (luminal A, stage II)...

With breast cancer screening programs becoming more available worldwide and covering larger age ranges, the prevalence of impalpable breast pathology is increasing. Whilst there is a 'tried and tested' technique for localizing occult lesions, the market for alternative methods is increasing and is estimated to pass $1 billion by 2024. In this article, we review the techniques currently available for localization of occult breast lesions and discuss the pros and cons of each.

We report 4 patients with occult breast cancer(OBC)who underwent breast conserving therapy(BCT)after neoadjuvant chemotherapy(NAC). All patients complained of axillary tumor and were diagnosed by core needle biopsy. Pathological examination of the axillary lymph nodes proved that 3 cases were adenocarcinomas and 1 case was squamous cell carcinoma, but imaging studies could not depict any primary lesions in the breast and other organs. Since distant metastasis was not observed, BCT with axillary lymph node dissection(ALND)was performed after NAC...

We report a case of occult breast cancer. A 61-years-old woman underwent tumorectomy of right axillary mass. Pathological diagnosis was adenocarcinoma. Two years after, right axillary mass was discovered again. Wide local excision, axillary lymph node dissection and radiation therapy of the breast was performed. Pathological findings showed lymph node metastasis of breast cancer, or primary cancer of the axially tail of the breast. Ten months after second operation, she presented an axillary mass again. She underwent resection of the axillary tumor...

Purpose To investigate the association between preoperative breast magnetic resonance (MR) imaging and surgical outcomes in patients with invasive lobular carcinoma (ILC) by using propensity score matching to decide whether MR examination is beneficial in the ILC subtype of breast cancer. Materials and Methods The authors identified 603 patients with ILC who underwent surgery between January 2005 and December 2016. Of the 603 patients, 369 (61.2%) underwent MR imaging. The authors calculated the MR detection rate of additional lesions that were occult at mammography and ultrasonography and analyzed any alterations in surgical management...

The presence of micrometastatic disease will ultimately determine the breast cancer-specific mortality of patients treated according to current guidelines. Minimal residual disease (i.e., occult tumor, not detected by conventional tests) may exist in two forms: a dormant form of only micrometastasis and a more aggressive "awakened" form where CTCs (circulating tumor cells) are actively disseminating. The hypothesis is that patients with CTCs have a more advanced or aggressive disease (that the cancer has "awoken" and there is active dissemination), whereas those patients with only micrometastasis have "dormant" disease and, although at risk of future relapse, may not do so for many years...

OBJECTIVE: The purpose of this study was to evaluate our initial experience with gamma imaging-guided vacuum-assisted breast biopsy in women with abnormal findings. MATERIALS AND METHODS: A retrospective review of patients undergoing breast-specific gamma imaging (BSGI), also known as molecular breast imaging (MBI), between April 2011 and October 2015 found 117 nonpalpable mammographically and sonographically occult lesions for which gamma imaging-guided biopsies were recommended...

Molecular breast imaging (MBI), also called breast-specific gamma imaging (BSGI), has been an integral component of our breast imaging practice for over a decade. Unlike mammography and ultrasound that are based on anatomy, MBI is a physiologic approach to breast cancer detection. MBI detects additional foci of occult breast cancer in 9.0% of women with newly diagnosed breast cancer, has a high sensitivity for detecting high-risk lesions, and detects 98% of invasive breast cancer and 91.0% of ductal carcinoma in situ...

Mammography is the gold standard for breast cancer screening. However, with increasing awareness among patients and health care providers of mammography limitations especially in dense breasts, supplemental screening for breast cancer with ultrasound and magnetic resonance imaging has been expanding. The roles of both in screening need to be re-examined. This article reviews the efficacy, utility, and feasibility of ultrasound as a screening tool for the early detection of occult breast cancer.

The relation between cancer and thrombosis is well known. In fact, the presence of an occult malignancy in patients with unprovoked venous thromboembolism (VTE) is named after a famous 19th century French physician; it is called Trousseau's sign. In this commentary, I elaborate upon findings from a recent individual patient data meta-analysis on Trousseau's sign. This study demonstrated that extensive screening to unmask an occult malignancy in unprovoked VTE is no better than 'simple' history taking and physical examination, alongside age-specific and gender-specific national cancer screening e...

BACKGROUND: High-grade serous carcinoma (HGSC) is the most common tubo-ovarian cancer. The fallopian tube harbours the precursor lesion: serous tubal intraepithelial carcinoma (STIC). Bilateral salpingo-oophorectomy is an effective risk-reducing surgical (RRS) strategy for breast cancer susceptibility gene mutation carriers (BRCAm). The value of RRS in those without defined genetic risk is unknown but these women represent a substantial cohort in prophylactic surgical practice. METHODS: This is a retrospective review of RRS at an Irish university teaching hospital...

BACKGROUND: Oral lesions have been reported among the first signs of an undiagnosed metastatic disease. Accurate diagnosis of an occult metastasis remains critical in determining the treatment course. Previous studies regarding oral metastatic tumors present varied data regarding the most frequent metastases to the oral cavity. These discrepancies echo the changes in incidence rates for certain malignancies over time and demonstrate the need for periodic updates in oral metastasis studies...
