Adenosquamous carcinoma of the breast is a rare subtype of metaplastic carcinoma, which accounts for <1% of invasive breast malignancy. Metaplastic carcinoma is usually high grade and aggressive with typically reported benign imaging features when compared to invasive ductal carcinoma. However, the adenosquamous variant is a subtype with a more favorable prognosis. Within the literature, there is limited imaging description with case studies focusing on metaplastic carcinoma. Herein, we report seven cases of the adenosquamous subtype describing the imaging findings with correlation to clinical history and pathology. The majority of patients (n = 6) presented with palpable breast masses. One patient was identified through screening mammography. Mammographically (n = 6), tumors appeared as irregular masses. Sonographically (n = 7), tumors appeared as irregular masses ranging from solid to mixed solid/cystic masses. On MRI (n = 1), one tumor appeared as an irregular rim enhancing mass. FDG PET/CT (n = 2) and whole-body bone scan (n = 1) were also available for review. The majority of tumors were low-grade (n = 6) with only one high-grade tumor. This case series of seven patients demonstrated predominantly suspicious imaging features despite the majority being low-grade tumors.

Low-grade adenosquamous carcinoma is a rare histologic subtype of breast carcinoma that has a variable mammographic and sonographic appearance, which overlaps with both benign and malignant neoplasms. Because of its lack of unique imaging features, a diagnosis of low-grade adenosquamous carcinoma is based on histopathology. The recognition of this entity is an important consideration in the differential diagnosis of breast masses and carries implications for prognosis, which is more favorable than other types of breast carcinoma.

One hundred cases of histologically proven invasive ductal carcinomas were histologically graded based on modified Bloom and Richardson Grading. Out of these 17 cases each of low grade, intermediate grade, and high grade invasive ductal carcinomas were selected for Immunostaining using the monoclonal antibodies Cyclin D1,pP53 and Her2/neu. It was found that for all three monoclonal antibodies the lowest histological grade of Invasive Ductal Carcinoma of the Breast showed the lowest positivity with Cyclin D1 ( 11.76%) and p53 ( 17.64%) and Her2/neu ( 47.05%). The intermediate grade tumour showed ( 70.58% ) positivity with Cyclin D1 and 58.58 % in p53 and Her2/neu. The high grade invasive ductal carcinoma of the breast showed the highest positivity of Cyclin D1 (76.47%) , p53 (88.24% ) ,Her2/neu ( 94.12% ); These suggest that Cyclin D1 , P53 and Her2/neuimmunoexpression positivity increases with rising histological grades of invasive ductal carcinoma of breast.

Background. We previously showed that grading can prognosticate the outcome of retroperitoneal liposarcoma (LPS). In the present study, we aimed to explore the impact of pathological stratification using grading on the clinical outcomes of patients with advanced well-differentiated LPS (WDLPS) and dedifferentiated LPS (DDLPS) treated with trabectedin. Patients: We included patients with advanced WDLPS and DDLPS treated with trabectedin at the Fondazione IRCCS Istituto Nazionale dei Tumori between April 2003 and November 2019. Tumors were categorized in WDLPS, low-grade DDLPS, and high-grade DDLPS according to the 2020 WHO classification. Patients were divided in two cohorts: Low-grade (WDLPS/low-grade DDLPS) and high-grade (high-grade DDLPS). Results: A total of 49 patients were included: 17 (35%) in the low-grade cohort and 32 (65%) in the high-grade cohort. Response rate was 47% in the low-grade cohort versus 9.4% in the high-grade cohort (logistic regression p = 0.006). Median progression-free survival (PFS) was 13.7 months in the low-grade cohort and 3.2 months in the high-grade cohort. Grading was confirmed as an independent predictor of PFS in the Cox proportional-hazards regression multivariable model (adjusted hazard ratio low-grade vs. high-grade: 0.45, 95% confidence interval: 0.22–0.94; adjusted p = 0.035). Conclusions: In this retrospective case series, sensitivity to trabectedin was higher in WDLPS/low-grade DDLPS than in high-grade DDLPS. If confirmed in larger series, grading could represent an effective tool to personalize the treatment with trabectedin in patients with advanced LPS.

ObjectiveTo confirm the diagnostic performance of computed tomography (CT)-based texture analysis (CTTA) and magnetic resonance imaging (MRI)-based texture analysis for grading cartilaginous tumors in long bones and to compare these findings to radiological features.Materials and MethodsTwenty-nine patients with enchondromas, 20 with low-grade chondrosarcomas and 16 with high-grade chondrosarcomas were included retrospectively. Clinical and radiological information and 9 histogram features extracted from CT, T1WI, and T2WI were evaluated. Binary logistic regression analysis was performed to determine predictive factors for grading cartilaginous tumors and to establish diagnostic models. Another 26 patients were included to validate each model. Receiver operating characteristic (ROC) curves were generated, and accuracy rate, sensitivity, specificity and positive/negative predictive values (PPV/NPV) were calculated.ResultsOn imaging, endosteal scalloping, cortical destruction and calcification shape were predictive for grading cartilaginous tumors. For texture analysis, variance, mean, perc.01%, perc.10%, perc.99% and kurtosis were extracted after multivariate analysis. To differentiate benign cartilaginous tumors from low-grade chondrosarcomas, the imaging features model reached the highest accuracy rate (83.7%) and AUC (0.841), with a sensitivity of 75% and specificity of 93.1%. The CTTA feature model best distinguished low-grade and high-grade chondrosarcomas, with accuracies of 71.9%, and 80% in the training and validation groups, respectively; T1-TA and T2-TA could not distinguish them well. We found that the imaging feature model best differentiated benign and malignant cartilaginous tumors, with an accuracy rate of 89.2%, followed by the T1-TA feature model (80.4%).ConclusionsThe imaging feature model and CTTA- or MRI-based texture analysis have the potential to differentiate cartilaginous tumors in long bones by grade. MRI-based texture analysis failed to grade chondrosarcomas.

Objective: The current study was carried out to assess the value of positron emission tomography (PET)/CT on the diagnosis and staging of primary musculoskeletal tumors. Methods: PET–CT test results and histopathological study reports of all the patients with primary musculoskeletal tumors in our department from January 2006 to July 2015 were retrospectively reviewed. Maximum standardized uptake value (SUVmax) in these PET–CT reports were recorded and analyzed respectively for each type of sarcoma. Results: A total of 255 patients were included in the final analysis. Sensitivity of SUVmax based diagnosis was 96.6% for primary malignant osseous sarcomas and 91.2% for soft tissue sarcomas. SUVmax of high-grade osseous sarcomas (average 8.4 ± 5.5) was significantly higher (p < 0.001) than low-grade osseous sarcomas (average 3.9 ± 1.8); based on current case series, SUVmax of high-grade soft tissue sarcomas (7.5 ± 5.1) was not significantly different (p = 0.229) from that of low-grade soft tissue sarcomas (5.3 ± 3.7). Significant decrease of SUVmax value after chemotherapy was associated with favorable prognosis in patients with osteosarcoma. Conclusion: Results of the current study indicate that, the SUVmax based application of PET–CT can be a valuable supplementary method to histopathological tests regarding the diagnosis and staging of primary musculoskeletal sarcomas. Advances in knowledge: SUVmax based application of PET–CT is a highly sensitive method in diagnosis of primary osseous and soft tissue sarcomas in Chinese patients.

Abstract Context.—Alterations in molecular elements derived from the CXC chemokine receptor 4 (CXCR4)/stromal-derived factor 1 (SDF-1) cytokine system have been found to strongly correlate with neoplastic progression leading to metastasis in a number of tumors, including osteosarcoma. Excluding hematologic malignancies, chondrosarcoma of bone is the most common primary malignant tumor of bone in adults in the United States. Like osteosarcoma, chondrosarcoma preferentially metastasizes to lung, bone, and very rarely to regional lymph nodes. However, the role of the signal pathway(s) driving neoplastic progression in chondrosarcoma has not yet been clearly elucidated. Objective.—To test whether CXCR4 was detectable in chondrosarcoma and whether CXCR4 expression levels correlated with chondrosarcoma grade. Design.—Twenty-two chondrosarcoma samples banked at our institution between 2001 and 2006 were retrieved for study. By using invasive ductal carcinoma of the breast and osteosarcoma as the positive controls, immunohistochemistry was performed on paraffin-embedded tissue sections and the intensity of the tumor cells was analyzed by morphometric techniques. Results.—All chondrosarcoma cases (22 of 22) were immunoreactive for CXCR4. However, the staining intensity of the CXCR4 between the low- and high-grade groups was significantly different. There was a higher staining intensity in high-grade chondrosarcoma cells (P &lt; .001). Conclusion.—CXCR4 is expressed in chondrosarcomas. CXCR4 expression levels were higher in high-grade chondrosarcoma cells than in low-grade specimens. A larger number of cases will be required to confirm these results and expand the observation, but preliminary data would argue for CXCR4 immunohistochemistry as a potential marker for biologic aggressiveness in chondrosarcoma of bone.

Purpose: The question of overtreatment of ductal carcinoma in situ (DCIS) was raised because a significant proportion of especially low-grade DCIS lesions never progress to invasive cancer. The rationale for the present study was to analyze the value of stereotactic vacuum-assisted biopsy (VAB) for complete removal of DCIS, focusing on the relationship between the absence of residual microcalcifications after stereotactic VAB and the histopathological diagnosis of the definitive surgical specimen. Patients and Methods: Data of 58 consecutive patients diagnosed with DCIS by stereotactic VAB in a single breast center between 2012 and 2017 were analyzed. Patient records from the hospital information system were retrieved, and mammogram reports and images as well as histopathology reports were evaluated. The extent of microcalcifications before and after biopsy as well as the occurrence of DCIS in biopsy and definitive surgical specimens were analyzed and correlated. Results: There was no correlation between the absence of residual microcalcifications in the post-biopsy mammogram and the absence of residual DCIS in the final surgical specimen (p = 0.085). Upstaging to invasive cancer was recorded in 4 cases (13%) but occurred only in the group that had high-grade DCIS on biopsy. Low-grade DCIS was never upgraded to high-grade DCIS in the definitive specimen. Conclusions: The radiological absence of microcalcifications after stereotactic biopsy does not rule out residual DCIS in the final surgical specimen. Since upstaging to invasive cancer is seen in a substantial proportion of high-grade DCIS, the surgical excision of high-grade DCIS should remain the treatment of choice.
