Methods: This retrospective study included 196 advanced breast cancer patients who had the Oncomine next generation sequencing analysis. The clinicopathologic parameters were recorded for each individuals including age, tumor type, grade, ER, PR, HER2, and recurrence free survival. Results: PIK3CA mutations were detected in 77.5% (152/196) of advanced breast cancer patients, 129 (84.8%) of which contained single mutations, 20 (13.1%) of which contained double mutations, and 3 (2%) of which contained triple mutations. Double PIK3CA mutated tumors were mostly seen in postmenopausal women, had lower combined histologic grade, and were enriched in hormone receptor positive human epidermal growth factor receptor negative (HR+/HER2-) disease. Double PIK3CA mutations were more frequently associated with concurrent mutations of ESR1 (p=0.017) and ARID1A (p=0.054) compared to single PIK3CA mutations. No significant progression free survival differences were observed between PIK3CA mutated and wild-type groups and between double and single PIK3CA mutated groups when applied to all patients or HR+/ HER2- patients. Conclusion: Double PIK3CA mutated advanced breast cancer have similar clinicopathologic features as single mutated ones but demonstrate unique molecular features.","PeriodicalId":48612,"journal":{"name":"Journal of Pathology Clinical Research","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135550765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He also had growth and mental retardation since 3 years of age. His thyroid profile records revealed a severe degree of hypothyroidism and he was on thyroxine supplement since then. He underwent a right hemithyroidectomy for the right-sided nodular goitre causing on-and-off dyspnea. The gross specimen measured 5x4x3cm, which on cut section showed partially encapsulated multi-nodular solid areas. Microscopy yielded marked architectural complexity and prominent cellular and nuclear pleomorphism that mimicked a thyroid malignancy; for eg., a poorly differentiated papillary or follicular carcinoma. However, a thorough assessment of a range of histo-morphological features in the context of clinical history clinched the diagnosis of dyshormonogenetic goitre. One year postoperatively the patient is doing well on Thyroxine supplement. This case report reviews the literature about this rare benign entity of dyshormonogenetic goitre which closely mimics thyroid malignancy, notably a follicular malignancy on microscopy owing to its cytoarchitectural complexity and nuclear atypia. Hence, knowledge of its clinical presentation, gross and diverse microscopic features is extremely important to avoid misdiagnosis and thereby clinical management.","PeriodicalId":48612,"journal":{"name":"Journal of Pathology Clinical Research","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135551007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 21-year-old gravida 3 para 1-0-1-1 with the history of a prior C-section presented at 35 weeks of gestation with the complaint of decreasing or absent fetal movements, previously there were no complications during her pregnancy. She underwent an emergent C-section due to non-reassuring fetal heart tones and delivered a female infant weighing 2145 grams without malformation and Apgar scores of 6 and 8 at 1 and 5 minutes. The premature neonate was admitted to the neonatal intensive care unit (NICU) and was discharged a few days later in good health and has done well since. The placenta weighed 768 grams with a three-vessel umbilical cord. The fetal surface was blue-gray and had multiple markedly dilated tortuous vessels (ranging in diameter from 0.5-1.4 cm) which were attached to a single area on the fetal surface. A Verhoeff-Van Gieson stain was negative for elastic fibers. The placental disc had a 7.1 cm peripheral infarct involving approximately 10% of the disc. There have been 3 cases reported previously in which two were associated with intrauterine growth restriction and one with molar transformation. In conclusion, placental serpentine aneurysm is a rare finding and unlike prior cases was associated with prematurity, decreased fetal movements, and nonreassuring fetal heart tones; a good outcome occurred because of prompt medical intervention.","PeriodicalId":48612,"journal":{"name":"Journal of Pathology Clinical Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135551011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the application of molecular approaches in pN0M0 MLA diagnosis has not been well investigated. Here, we performed next-generation sequencing (NGS) analysis in 45 pN0M0 MLA patients (101 lesion pairs) who were initially diagnosed as having MPLA by comprehensive histologic assessment (CHA). Five additional patients with intrathoracic metastases were used as positive controls, while 197 patients with unifocal lung adenocarcinomas (425 random lesion pairs) were used as negative controls. By utilizing a predefined NGS criterion, all IPMs in the positive control group could be accurately classified, whereas 13 lesion pairs (3.1%) in the negative control cohort were misdiagnosed as IPMs. Additionally, 14 IPM lesion pairs were diagnosed in the study group, with at least 7 misdiagnoses. We thus developed a refined algorithm, incorporating both NGS and histologic results, that could correctly diagnose all the known MPLAs and IPMs. In particular, all IPMs identified by the refined algorithm were diagnosed to be IPMs or suspected IPMs by CHA reassessment. The refined algorithm-diagnosed MPLAs patients also had significantly better progression-free survival than the refined algorithm-diagnosed IPMs (p < 0.0001), which is superior to conventional NGS or CHA diagnoses. Overall, we developed an NGS-based algorithm that could accurately distinguish IPMs from MPLAs in MLA patients. Our results demonstrate a promising clinical utility of NGS to complement traditional CHA-based MLA diagnosis and help determine patient staging and treatment.","PeriodicalId":48612,"journal":{"name":"Journal of Pathology Clinical Research","volume":"9 2","pages":"108-120"},"PeriodicalIF":4.1,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/0f/81/CJP2-9-108.PMC9896159.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10730314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its growing importance underpinned by the European in vitro diagnostics regulation or broad preanalytical programs by the National Institutes of Health, little is known about its empirical occurrence in biobanked surgical specimen. In several steps, the Tissue Bank Bern achieved a fully informative SPREC code with insights from 10,555 CIT, 4,740 WIT, and 3,121 FIT values. During process optimization according to LEAN six sigma principles, we identified a dual role of the SPREC code as a sample characteristic and a traceable process parameter. With this preanalytical study, we outlined real-life data in a variety of organs with specific differences in WIT, CIT, and FIT values. Furthermore, our FIT data indicate the potential to adapt the SPREC fixation toward concrete paraffin-embedding time points and to extend its categories beyond 72 h due to weekend delays. Additionally, we identified dependencies of preanalytical variables from workload, daytime, and clinics that were actionable with LEAN process management. Thus, streamlined biobanking workflows during the day were significantly resilient to workload peaks, diminishing the turnaround times of native tissue processing (i.e. CIT) from 74.6 to 46.1 min under heavily stressed conditions. In conclusion, there are surgery-specific preanalytics that are surgico-pathologically limited even under process optimization, which might affect biomarker transfer from one entity to another. Beyond sample characteristics, SPREC coding is highly beneficial for tissue banks and Institutes of Pathology to track WIT, CIT, and FIT for process optimization and monitoring measurements.","PeriodicalId":48612,"journal":{"name":"Journal of Pathology Clinical Research","volume":"9 2","pages":"137-148"},"PeriodicalIF":4.1,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pathsocjournals.onlinelibrary.wiley.com/doi/epdf/10.1002/cjp2.305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9295781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
