RESUMEN

We present herein an extension to our recently developed and published method termed "Fractionation of Nodal Cell Suspension" (FNCS). The method enables efficient subcellular fractionation into nuclear (N) and cytosolic (C) compartments of extremely fibrous and problematic metastatic axillary lymph node (mALN) tissue, using the entire nodule. For the purpose of the present study, a case of invasive lobular breast cancer (BC) patient with pT2N3aMx status and defined primary tumor markers (ERα 8, PR-B 8, and HER2 score 0) was available. Initially, the mALN tissue of this patient was analyzed by immunohistochemistry (IHC), and a positive correlation of nodal ERα, PR-B and HER2 biomarkers to those of the primary tumor was obtained. Subsequently, the mALN was FNCS fractionated into N and C, and Western blot (WB) analysis demonstrated a single band for ERα, PR-B and nuclear loading control (HDAC1) in nuclear, but not in the cytosolic compartments, confirming the efficiency of our fractionation protocol. At the same time, HER2 bands were not observed in either compartment, in accordance with HER2 negativity determined by IHC in both primary tumor and mALN tissue. In conclusion, by confirming the nuclear expression of ERα and PR-B biomarkers in metastatic loci, we demonstrate the purity of the FNCS-generated compartments - the protocol that offers a reliable tool for further analysis of nuclear versus cytosolic content in downstream analysis of novel biomarkers in the whole mALN of BC patients.

RESUMEN

Invasive lobular breast cancer (ILC) is characterized by a relatively high risk for late recurrence and a unique metastatic pattern with an increased risk for metastasis to gynecologic organs and peritoneum. We present a unique case of recurrent ILC with metastasis to the abdominal peritoneum as well as the uterine myometrium and cervix. Treatment was complicated by the discovery of concomitant uterine carcinosarcoma. This patient was effectively treated with a combination of hormonal therapy for her metastatic ILC and a combination of chemotherapy and immunotherapy for uterine carcinosarcoma. Molecular evaluation revealed a characteristic CDH1 mutation within the ILC and a PI3KCA mutation within the uterine carcinosarcoma, both of which have been linked to epithelial-to-mesenchymal transitions. Examination of the tumor immune microenvironment revealed proportionally more cytotoxic NK cells. This robust immune infiltration may be an indicator of the response to immunotherapy observed in this tumor or a result of the metastatic breast cancer within the uterus. This report provides a characterization of the molecular and immunologic landscape in this case with metastatic ILC and uterine carcinosarcoma.

RESUMEN

Metastasis to the pancreas from malignant tumors is a rare event, representing only 1% to 2% of all pancreatic neoplasms. They occur in 2 different clinicopathological settings: as a manifestation in widespread metastatic disease or as an isolated mass in the pancreas. We report the case of a 41-year-old woman who had a history of invasive lobular breast cancer treated with radical surgery, chemotherapy, and radiotherapy. After 21 years of total remission, she presented for severe lower back pain with jaundice, nausea, and loss of 9 kg in 3 months. Abdominal computed tomography demonstrated a hyper vascularized, irregular solid lesion of 2.6 cm × 2.1 cm in the head of the pancreas with discreet biliary duct dilatation and coelio-mesenteric enlarged lymph nodes measuring 2 cm. The diagnosis of pancreatic metastasis from a lobular breast carcinoma was made by percutaneous biopsy of pancreatic lesion. The multidisciplinary committee decided a palliative treatment. The patient received chemotherapy. The take home message from his case is that we should keep in mind the hypothesis of a solitary metastasis to the pancreas, when the pancreatic lesion develops in a patient who had a clinical history of previous neoplasm especially in those which is known to potentially metastasize to pancreas.

RESUMEN

BACKGROUND: The metastasis of primary breast invasive lobular carcinoma to the gastrointestinal tract and skin is a rare phenomenon, with the simultaneous occurrence of both transfers being more uncommon. CASE PRESENTATION: This article reports a case of a patient with hormone receptor-positive, HER2-negative breast invasive lobular carcinoma with gastrointestinal tract and skin metastases. The patient was assessed by a second-look ultrasound and diagnosed by subsequent ultrasound-guided needle biopsy. Following endocrine therapy, a favorable effect was observed, with significant regression of the primary breast lesion, cutaneous metastases, and gastrointestinal metastases. CONCLUSION: Patients with breast invasive lobular carcinoma should be alert to the possibility of breast cancer metastasis, even if there are no obvious symptoms or signs, when they encounter rapidly progressive cutaneous nodules or plaques, or if they possess gastrointestinal abnormalities. For patients with negative breast ultrasonography for the first time, after combining mammography, Contrast-enhanced Spectral Mammography (CESM) or Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) examinations, if breast cancer is highly suspected, second-look ultrasound is particularly crucial at this juncture, which is the key prerequisite for breast needle biopsy and obtaining the gold standard of pathology.

RESUMEN

BACKGROUND: Intra-ductal cancer (IDC) is the most common type of breast cancer, with intra-lobular cancer (ILC) coming in second. Surgery is the primary treatment for early stage breast cancer. There are now irrefutable data demonstrating that the immune context of breast tumors can influence growth and metastasis. Adjuvant chemotherapy may be administered in patients who are at a high risk of recurrence. Our goal was to identify the processes underlying both types of early local recurrences. METHODS: This was a case-control observational study. Within 2 years of receiving adjuvant taxan and anthracycline-based chemotherapy, as well as modified radical mastectomy (MRM), early stage IDC and ILC recurred. Vimentin, α-smooth muscle actin (SMA), platelet-derived growth factor (PDGF), matrix metalloproteinase (MMP1), and clustered differentiation (CD95) were investigated. RESULTS: Of the samples in the ductal type group, 25 showed local recurrence, and 25 did not. Six individuals in the lobular-type group did not experience recurrence, whereas seven did. Vimentin (p = 0.000 and 0.021), PDGF (p = 0.000 and 0.002), and CD95 (p = 0.000 and 0.045) expressions were significantly different in ductal and lobular carcinoma types, respectively. Measurement of ductal type was the sole significant difference found in MMP1 (p = 0.000) and α-SMA (p = 0.000). α-SMA and CD95 were two variables that helped the recurrence mechanism in the ductal type according to the pathway analysis. In contrast, the CD95 route is a recurrent mechanism for the lobular form. CONCLUSIONS: While the immune system plays a larger role in ILC, the tumor microenvironment and immune system both influence the recurrence of IDC. According to this study, improving the immune system may be a viable cancer treatment option.

RESUMEN

Invasive lobular carcinoma (ILC) is the second most common subtype of invasive breast cancer and sometimes presents with an unusual metastatic pattern. Its gastric metastasis is difficult to differentiate from primary adenocarcinoma. This report presents a case of breast ILC for which the initial presentation was gastric metastasis. A 62-y-old woman presented with gastric outlet obstruction secondary to a gastric mass that had been diagnosed on upper gastrointestinal endoscopy and biopsy. The patient had been referred for 18F-FDG PET/CT for staging. The baseline 18F-FDG PET/CT scan demonstrated extensive axillary nodal and gastric metastases with a breast mass, which raised suspicion of a primary breast carcinoma. Distinguishing primary gastric adenocarcinoma from metastatic breast ILC is essential, considering that the 2 diagnoses lead to divergent treatments. Therefore, this entity needs to be considered in the differential diagnosis in clinical practice.

RESUMEN

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor of intermediate malignancy and uncertain differentiation. To date, only four patients diagnosed with AFH located in the chest wall have been described. Herein, we describe a 44-year-old woman diagnosed with breast infiltrating lobular carcinoma. During the imaging study with positron emission tomography-computerized tomography scan, a 4 cm solid lesion located in the chest wall was identified. Fine-needle aspiration followed by surgical excision with intraoperative frozen section study was performed. The combined histomorphologic, immunohistochemical, and molecular findings confirmed the diagnosis of AFH. In this report, we describe, to the best of our knowledge, the first patient with synchronous AFH and breast cancer.

RESUMEN

INTRODUCTION: The histological grade of a tumor is an important prognostic indicator in both primary breast cancer and metastatic. We aimed to show the distribution of bone metastasis locations across different histological subtypes of breast cancer and how they relate to each. METHODS: The cohort retrospective study comprised 65 patients diagnosed with bone-only metastatic breast cancer, all female. The secondary statistics for 2014 to 2022 were derived from breast cancer registration data collected to determine the relationships between patterns of bone metastases sites and histopathological grading in various histological categories. RESULTS: The average age was 44.28±9.80 years (25-62 years), with 38 patients (58.5%) diagnosed with Invasive Ductal Carcinoma (IDC) and 27 patients (41.5%) with Invasive Lobular Carcinoma (ILC). Grade III were found in 34 patients (50.8%), Grade II in 31 patients (47.7%) and Grade I in one patient (1.5%). The most common sites of bone metastases are costae, followed by femur, vertebrae and pelvic. Vertebrae and costae metastasis are significantly correlated with histological grading and breast cancer pathology (p: 0.027 and 0.033, respectively). CONCLUSION: There is a considerable difference between vertebrae and costae metastasis in terms of histological grading and breast cancer pathology which indicates the higher grade contains a greater variety of bone metastases sites.

RESUMEN

The metastasis of breast cancer to the gastrointestinal tract is rare. Herein, we presented the case of an 85-year-old woman who had a history of invasive lobular carcinoma and experienced complete colon rupture due to relatively low-energy trauma. The patient underwent bilateral total mastectomy and axillary dissection following preoperative chemotherapy 6 years ago. She had a local recurrence 2 years after the surgery and underwent chemotherapy. Subsequently, the cancer metastasized to the thoracolumbar area and retroperitoneum. In addition, the patient fell from a height of 30 cm while hanging laundry and her abdomen hit a hose reel. Emergency surgery was performed, and the entire circumference of the sigmoid colon was ruptured. The ruptured colon lesion was resected, and the stump was closed. A double-barrel transverse colostomy was created as it was impossible to lift the stump up to the abdominal wall. Histopathological examination revealed the invasive lobular carcinoma metastasis and a linitis plastica-like change of the colon wall, which probably consequently weakened. In addition, minimal trauma can damage the gastrointestinal tract that had invasive lobular carcinoma metastasis.

RESUMEN

Case report: A sixty-five-year-old female patient underwent surgery for severe gastrointestinal symptoms, following an alarming CT image. Laparotomy revealed irresectable gastric cancer and peritoneal carcinosis. Palliative gastro-jejunostomy and ileo-descendostomy were performed. The endoscopic diagnosis - linitis plastica - and the intraoperative macroscopic appearance matched and agreed on the histologically presumed shigillocellular carcinoma. Three years following the initial abdominal symptoms, histological samples taken from newly detected cutaneous metastases which developed during oncological palliative treatment verified occult lobular breast carcinoma. Histological revision of the sample taken from abdominal exploration confirmed the latter diagnosis. The hormone receptor positive, human epidermal growth factor receptor-2 negative malignancy showed very good regression for the palliative hormone treatment. Discussion: About ten percent of breast cancer cases are lobular carcinomas, which are more often multicentric, bilateral, occult and have a propensity to metastasize to serous membranes, abdominal and pelvic viscera. Due to the increasing survival of breast cancer patients, the number of abdominal metastases of breast cancer is expected to increase. Histological confirmation is indispensable even in case of advanced abdominal malignancies, especially in the case of an unusual medical history. The currently rare case demonstrates the need for multidisciplinary cooperation in all diagnostic and therapeutic fields of breast cancer.

RESUMEN

Gastrointestinal tract is an uncommon site of breast cancer metastasis. Rectal linitis plastica (RLP) is a rare presentation of rectal neoplasia, both primary and secondary, and refers to a diffuse infiltration of the wall by an infiltrating carcinoma. Diagnostic assessment of RLP may be challenging since cross-sectional imaging and endoscopic findings may be nonspecific, and endoscopic biopsies are frequently non-diagnostic due to the submucosal disease localization. Endoscopic ultrasound (EUS) with fine needle biopsy (FNB) is widely used for the diagnostic assessment of sub-epithelial lesions of upper and lower gastrointestinal tract. However, data about the use of EUS in case of rectal linitis plastica are very poor. We present a case of rectal metastasis as the first presentation of lobular breast cancer, presenting as rectal linitis plastica and diagnosed with EUS-FNB.

RESUMEN

BACKGROUND: Late distant recurrence is a challenge for the treatment of invasive lobular carcinoma (ILC) of the breast. Despite in-depth characterisation of primary ILC, the molecular landscape of metastatic ILC is still only partially understood. METHODS: We retrospectively identified 38 ILC patients from the tissue banks of six European institutions. DNA extracted from patient matched primary and metastatic FFPE tissue blocks was whole genome sequenced to compute somatic copy number aberrations. This, in turn, was used to infer the evolutionary history of these patients. FINDINGS: The data show different metastatic seeding patterns, with both an early and late divergence of the metastatic lineage observed in ILC. Additionally, cascading dissemination from a metastatic precursor was a dominant rule. Alterations in key cancer driver genes, such as TP53 or CCND1, were acquired early while additional aberrations were present only in the metastatic branch. In about 30% of the patients, the metastatic lineage harboured less aberrations than the primary tumour suggesting a period of tumour dormancy or prolonged adaptation at the distant site. This phenomenon was mostly observed in tumours from de novo metastatic patients. INTERPRETATION: Our results provide insights into ILC evolution and offer potential paths for optimised ILC care. FUNDING: This work has received financial support from Les Amis de l'Institut Bordet, MEDIC, the Breast Cancer Research Foundation (BCRF) and the Belgian Fonds National de la Recherche Scientifique (F.R.S-FNRS).

RESUMEN

BACKGROUND: Breast cancer may differ biologically in patients aged over 80 years. The objective of the current study was to analyze the metastasis patterns and prognosis of elderly patients with metastatic breast cancer (MBC) and compare it to patients of other ages. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was utilized to select MBC patients from 2010 to 2015. Chi-squared test was used to compare clinicopathological characteristics among different aged groups. The Kaplan-Meier method and multivariate Cox model were utilized for survival analysis. RESULTS: A total of 10479 MBC patients were included, among which 1036 (9.9%) patients were aged over 80 years. Compared with other aged group, the elderly patients tended to have a higher proportion of HR+/Her2- subtype, white race, lower tumor differentiation, and receive less treatment, including surgery, chemotherapy and radiotherapy (P< 0.001). MBC patients with different age presented with distinctive metastatic patterns. The older patients were more likely to have lung metastasis, but less likely to have bone, brain, liver and multiple sites metastasis than the younger group (P <0.001). The proportion of TNBC subtype increased substantially in the older patients with brain metastasis, compared to the younger and middle-aged group. The old age was demonstrated to significantly associate with worse prognosis of MBC patients. Additionally, our findings also showed that older MBC patients could achieve dramatical overall survival benefit from surgery (HR = 0.58; P <0.001) and chemotherapy (HR = 0.59; P <0.001), but not the radiotherapy (HR = 0.96; P = 0.097). CONCLUSION: The elderly MBC patients presented with distinctive metastatic patterns, clinical characteristics, and prognostic outcomes compared with younger patients. Our findings could assist clinicians in making appropriate therapeutic decision.

RESUMEN

Metastatic invasive lobular breast cancer (ILC) to the colon is rare and usually ER-positive. We present an ER-negative case of metastatic ILC presenting as linitis plastica of the colon where [18 F]FES PET/MRI allowed the evaluation of the ER phenotypic transformation in the colonic metastasis from the ER-positive breast ILC in vivo.

RESUMEN

We evaluated the clinicopathologic features of 38 cases of metastatic lobular (n=33) or predominantly lobular (n=5) carcinoma involving the ovary. The patients were from 39 to 91 years of age (mean: 53 y). In 2 cases, the breast primary and ovarian metastasis were diagnosed synchronously, and in 5, the breast primary was only discovered after the metastatic carcinoma in the ovary was found. In the majority of cases (79%), both ovaries were involved; the mean ovarian tumor size was 5.9 cm. The ovarian tumors demonstrated a range of architectural patterns including macronodular (71%), diffuse/solid growth (87%), single-cell infiltration (87%), cords (74%), and small nests/clusters (50%). Nine cases demonstrated focal signet ring cell morphology. The associated stromal reaction ranged from none to marked, with almost half of cases demonstrating a marked stromal response, largely prominent sclerosis. A variety of neoplasms, most typically sex cord-stromal tumors, lymphoma/leukemia, and desmoplastic small round cell tumor, may enter the differential. In addition to the obvious help afforded in most cases by the clinical history, a combination of judicious sampling, particularly to unearth the delicate cords or single-cell growth of lobular carcinoma, appropriate consideration of the cytologic features of the neoplastic cells, and immunohistochemistry can resolve the diverse issues in differential diagnosis that may arise.

RESUMEN

BACKGROUND: Orbital metastasis of breast cancer is an unusual condition, especially in the absence of a previous diagnosis of primary breast cancer. The main MRI findings in patients with orbital metastasis are retroorbital soft tissue with thickening of extraocular muscles. Paradoxical enophthalmos secondary to fibrosis can be seen. CASE REPORT: In this case report, we present a 75-year-old female patient with left eye pain and blurred vision and retraction. Although there was no evidence of malignancy in the biopsy of the orbita; since the patient's complaints continued despite idiopathic pseudotumor treatment, mammography was recommended to rule out the possibility of breast cancer metastasis. Her mammography revealed a suspicious lesion in the left breast and proved to be pleomorphic invasive lobular cancer. CONCLUSION: Breast cancer metastasis should be kept in mind in women with pseudotumor -like the involvement of the orbita.
