Breast Implant-Associated Anaplastic Large Cell Lymphoma: A Case Report, Jennie Tan, Jamie Johnson-Eddy, Wesley Tang, Yanchun Li

Cooper Rowan Medical Journal

This report aims to review a case of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) by comparing the patient's course with the current literature.

BIA-ALCL is a specific type of T-cell lymphoma that can develop after breast implantation, but has only recently been recognized within the last decade. Although overall rare, certain types of breast implants have increased association with developing subsequent lymphoma. This case occurred after mastectomy with breast reconstruction for unilateral invasive ductal carcinoma with a textured, saline Allergan breast implant. BIA-ALCL manifested and was symptomatic nine years after implantation.

Idiopathic Pulmonary Fibrosis And Lung Cancer: Future Directions And Challenges, Ahmad Abu Qubo, Jamil Numan, Juan Snijder, Maria Padilla, John H.M. Austin, Kathleen M. Capaccione, Monica Pernia, Jean Bustamante, Timothy O’Connor, Mary M. Salvatore

Einstein Health Papers

Idiopathic pulmonary fibrosis (IPF) is a progressive disease of pulmonary scarring. New treatments slow disease progression and allow pulmonary fibrosis patients to live longer. Persistent pulmonary fibrosis increases a patient’s risk of developing lung cancer. Lung cancer in patients with IPF differs from cancers that develop in the non-fibrotic lung. Peripherally located adenocarcinoma is the most frequent cell type in smokers who develop lung cancer, while squamous cell carcinoma is the most frequent in pulmonary fibrosis. Increased fibroblast foci in IPF are associated with more aggressive cancer behaviour and shorter doubling times. Treatment of lung cancer in fibrosis is challenging …

Pediatric central nervous system (CNS) tumors represent the most common cause of cancer-related death in children aged 0-14 years. They differ from their adult counterparts, showing extensive clinical and molecular heterogeneity as well as a challenging histopathological spectrum that often impairs accurate diagnosis. Here, we use DNA methylation-based CNS tumor classification in combination with copy number, RNA-seq, and ChIP-seq analysis to characterize a newly identified CNS tumor type. In addition, we report histology, patient characteristics, and survival data in this tumor type. We describe a biologically distinct pediatric CNS tumor type (n = 31 cases) that is characterized by focal …

Department of Pathology and Laboratory Medicine

Background: The outcome of patients with simultaneous diagnosis of haematological malignancies (HM) and COVID-19 is unknown and there are no specific treatment guidelines.
Methods: We describe the clinical features and outcome of a cohort of 450 patients with simultaneous diagnosis of HM and COVID-19 registered in the EPICOVIDEHA registry between March 2020 to February 2022.
Results: Acute leukaemia and lymphoma were the most frequent HM (35.8% and 35.1%, respectively). Overall, 343 (76.2%) patients received treatment for HM, which was delayed for longer than one month since diagnosis in 57 (16.6%). An overall response rate was observed in 140 (40.8%) patients …

A Rare Metastatic Primary Rectal Melanoma In A Geriatric Male, Onyinye Ugonabo, Mujtaba Mohamed, Ebubechukwu Ezeh, Joseph Simmons, Jonathan Cuda, Shima Ghavimi

Internal Medicine

Primary rectal melanoma (PRM) is an uncommon malignancy whose etiology remains unknown. Most patients present with rectal bleeding. Distant metastasis is commonly seen in the lung and liver. The incidence rates for locoregional lymph node metastases on initial presentation are almost 60%. Histology and immunochemistry are useful and are the gold standard for diagnosis. The prognosis is very poor due to the late presentation of patients. Optimum surgical treatment remains controversial. Abdominoperineal resection was considered traditionally but over time, has been found to have no survival benefit. Current literature and studies, therefore, recommend wide local excision. The beneficial effects of …

Reporting Of Mycetoma Cases From Skin And Soft Tissue Biopsies Over A Period Of Ten Years: A Single Center Report And Literature Review From Pakistan, Mohammad Zeeshan, Saira Fatima, Joveria Farooqi, Kauser Jabeen, Arsalan Ahmed, Afreen Haq, Muhammad Omer Arif, Afia Zafar

Department of Pathology and Laboratory Medicine

Background: Mycetoma is an important neglected tropical disease associated with debilitation, disfigurement and death if not diagnosed and treated adequately. In Pakistan, mycetoma cases have frequently been diagnosed in histopathology and microbiology laboratories. However, there is scarcity of published data from this country. Therefore, the objectives of this study were to evaluate the frequency and type of mycetoma reported in skin and soft tissue biopsies from a single center over 10 years and review of published literature from Pakistan.
Method: This descriptive observational retrospective study was conducted at the Aga Khan University Hospital laboratory, Karachi, Pakistan. Laboratory data from 2009-2018 …

Use Of Autoreactive Antibodies In Blood Of Patients With Pancreatic Intraductal Papillary Mucinous Neoplasms (Ipmn) For Grade Distinction And Detection Of Malignancy, Niall Brindl, Henning Boekhoff, Andrea S Bauer, Matthias M Gaida, Hien Dang, Jörg Kaiser, Jörg D Hoheisel, Klaus Felix

Department of Surgery Faculty Papers

(1) Background: A reliable non-invasive distinction between low- and high-risk pancreatic intraductal papillary mucinous neoplasms (IPMN) is needed to effectively detect IPMN with malignant potential. This would improve preventative care and reduce the risk of developing pancreatic cancer and overtreatment. The present study aimed at exploring the presence of autoreactive antibodies in the blood of patients with IPMN of various grades of dysplasia. (2) Methods: A single-center cohort was studied composed of 378 serum samples from patients with low-grade IPMN (n = 91), high-grade IPMN (n = 66), IPMN with associated invasive cancer (n = 30), pancreatic …

Monocarboxylate Transporter 4 In Cancer-Associated Fibroblasts Is A Driver Of Aggressiveness In Aerodigestive Tract Cancers, Marina Domingo-Vidal, Diana Whitaker Menezes, Mehri Mollaee, Zhao Lin, Madalina Tuluc, Nancy J. Philp, Jennifer Johnson, Tingting Zhan, Joseph Curry, Ubaldo E. Martinez-Outshoorn

Department of Medical Oncology Faculty Papers

The most common cancers of the aerodigestive tract (ADT) are non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC). The tumor stroma plays an important role in ADT cancer development and progression, and contributes to the metabolic heterogeneity of tumors. Cancer-associated fibroblasts (CAFs) are the most abundant cell type in the tumor stroma of ADT cancers and exert pro-tumorigenic functions. Metabolically, glycolytic CAFs support the energy needs of oxidative (OXPHOS) carcinoma cells. Upregulation of the monocarboxylate transporter 4 (MCT4) and downregulation of isocitrate dehydrogenase 3α (IDH3α) are markers of glycolysis in CAFs, and upregulation of the …

Concurrent P53 Mutation In Egfr Mutant Non-Small Cell Lung Cancer Is Associated With Resistance To First And Second Generation Egfr Tyrosine Kinase Inhibitors, A Meta-Analysis, Marissa Viola, Adam Kolatorowicz, Jun Wang

Research Day

Epidermal growth factor receptor (EGFR) mutant lung cancers tend to respond well to EGFR tyrosine kinase inhibitors (TKIs). However, resistance has been described. Molecular studies have revealed that concurrent mutations of tumor driver genes are associated with TKI resistance. To delineate the role of concurrent mutation of tumor suppressor gene p53 in TKI resistance, a meta-analysis was performed using published observations of EGFR mutant lung cancer patients treated with first or second generation TKIs. 31 studies are included in the analysis following a search of PubMed. Probability of TKI resistance and progress free survival (PFS) were compared in patients with …

Response Of Eltrombopag In Immune Thrombocytopenia And Acquired Idiopathic Aplastic Anemia: A Single-Center Experience, Abdul Muqtadir Abbasi, Mohammad Usman Shaikh, Natasha Bahadur Ali, Maria Khan, Salman Muhammad Soomar

Section of Haematology/Oncology

Eltrombopag has been used in ITP and found its use in AA armamentarium recently. We retrospectively analyzed 61 patients at a tertiary care center in Pakistan from January 2015 to January 2021. They included patients with severe AA who were refractory to at least one course of immunosuppressive therapy and persistent/chronic ITP who have received at least one previous treatment for ITP. Responses to Eltrombopag in our population were comparable to real-world experiences while tolerable hepatotoxicity and GI issues were notable. We found Eltrombopag to be a safe and efficacious agent for treating patients with ITP and AA.

Chronic granulomatous inflammation is a common finding in lymphoproliferative disorders (LPDs), but it is important to exclude coexisting mycobacterium tuberculosis (MTB) especially in patients from areas of high endemicity. This case emphasizes the relevance of performing MTB culture on bone marrow exhibiting LPD and concomitant granulomas

Upregulation Of Cd36, A Fatty Acid Translocase, Promotes Colorectal Cancer Metastasis By Increasing Mmp28 And Decreasing E-Cadherin Expression, James Drury, Piotr G. Rychahou, Courtney O. Kelson, Mariah E. Geisen, Yuanyuan Wu, Daheng He, Chi Wang, Eun Y. Lee, B. Mark Evers, Yekaterina Y. Zaytseva

Surgery Faculty Publications

Altered fatty acid metabolism continues to be an attractive target for therapeutic intervention in cancer. We previously found that colorectal cancer (CRC) cells with a higher metastatic potential express a higher level of fatty acid translocase (CD36). However, the role of CD36 in CRC metastasis has not been studied. Here, we demonstrate that high expression of CD36 promotes invasion of CRC cells. Consistently, CD36 promoted lung metastasis in the tail vein model and GI metastasis in the cecum injection model. RNA-Seq analysis of CRC cells with altered expression of CD36 revealed an association between high expression of CD36 and upregulation …
