Breast examination revealed the presence of a 3-cm hard elastic mass in the C region of the right breast. Computed tomography (CT)\u0000further indicated metastases to the liver and lungs. Upon needle biopsy of the primary tumor, the patient was diagnosed with triple-negative (ER\u0000(-), PgR (-), HER2 (-)) invasive lobular carcinoma. Chemotherapy was successful in achieving a transient partial response (PR); however, the\u0000tumor later advanced to a progressive disease (PD) after five cycles of oral fluoropyrimidine derivative therapy (S-1). Re-biopsy of the primary\u0000tumor revealed that the tumor was triple-positive (ER (+), PgR (+), HER2 (+)). The patient was subsequently treated with anti-HER2 therapy\u0000and has since achieved complete response (CR). Although biological changes sometimes occur from the primary to the metastatic tumor, changes\u0000in the primary tumor itself during the course of treatment is a rare event. Furthermore, the transition from triple-negative to triple-positive status\u0000is very uncommon. Re-biopsy rarely changes the biological characteristics of a tumor; however, biological changes can have a significant impact\u0000on treatment if they do occur. Thus, it is important to perform a re-biopsy if the current treatment results in PD.","PeriodicalId":91401,"journal":{"name":"SM journal of clinical and medical imaging","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74430959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to test the\u0000sensitivity of detection and determine the extent of the lesion on the Dixon imaging versus conventional proton density weighted\u0000(PDW) imaging in the domain of bone stress injury (BSI) and obtain inter-reader performance.\u0000Methods: In this retrospective cross-sectional study, 32 consecutive BSI were compared on conventional imaging versus different\u0000Dixon images in terms of area of bone marrow edema, inter-trabecular fracture detection and fracture conspicuity. Inter-reader\u0000reliability was also evaluated. p<0.05 was considered statistically significant.\u0000Results: The Dixon imaging showed excellent quality except two cases with some motion degradation. BSI detection on Dixon\u0000water image is equivalent to the routine fat suppressed fluid sensitive intermediate weighted sequence. BSI area on water image is\u0000not significantly different from the intertrabecular lesion area on opposed-phase imaging (p=0.9531). The opposed-phase images\u0000detected more number of fractures than the water, PDW, & in-phase images (p<0.0001, =0.0008, and <0.0001, respectively) with\u0000superior fracture conspicuity than the water, PDW, & in-phase images (p value <0.0001, =0.0085, and =0.0035, respectively). Fair\u0000to moderate inter-reader agreement was seen.\u0000Conclusions: Dixon imaging is as sensitive as conventional fat suppressed fluid sensitive imaging of the knee for the identification of\u0000bone bruise with superior detection and improved characterization of the intertrabecular fractures.\u0000Advances in knowledge: In the domain of bone stress injury (BSI), Dixon opposed-phase MR images detect more number of fractures\u0000with better conspicuity than water-only, PDW, and in-phase images.","PeriodicalId":91401,"journal":{"name":"SM journal of clinical and medical imaging","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78217290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a local thermal ablative method,\u0000cryoablation is unique in that it preserves tumor associated antigens, releasing them into the circulation and allowing the immune system to\u0000mount a targeted, systemic anti-cancer response in a phenomenon known as the abscopal effect. Advances in our understanding of tumor biology\u0000and cancer immunology have simultaneously led to the development of various anti-cancer immunotherapies. Whether through stimulating an\u0000immune response or inhibiting immunosuppression, these therapies have demonstrated efficacy in the treatment of numerous cancers and\u0000represent a new frontier in cancer treatment. In recent years, several pre-clinical and clinical studies have sought to elucidate the potential\u0000synergy between combination immunotherapy and cryoablation with the hope of augmenting the abscopal effect. This emerging field of\u0000“cryoimmune” therapy, although still in its infancy, represents an exciting new direction in cancer treatment.","PeriodicalId":91401,"journal":{"name":"SM journal of clinical and medical imaging","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72871775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
