May 28th, 2022 - Heterogeneous masses developing in the pleural cavity are most often malignant and can pose diagnostic challenges. Fibrous tumors of the pleura, liposarcoma, thymoma or lipoma most frequently affect this anatomic area. Surgical exploration and resection are often mandatory to make the definitive diagnosis. We report the case of a 54-year-old women who presented with an epigastric and right sub ...

May 28th, 2022 - Pseudomyxoma peritonei (PMP) is a rare clinical syndrome. It originates from neoplasms of the appendix and leads to the formation of peritoneal implants and the accumulation of mucinous ascites. PMP represents a spectrum of low to high-grade disease. Despite aggressive management, many PMP patients recur, leading to debilitating symptoms and few treatment options. Therefore, scientists have con...

May 28th, 2022 - Chimeric antigen receptor T (CAR T) cell therapy achieved remarkable success in B-cell leukemia and lymphoma which led to its incorporation in treatment protocols for these diseases. CAR T cell therapy for chronic lymphocytic leukemia (CLL) patients showed less success compared to other malignant tumors. In this review, we discuss the published results regarding CAR T cell therapy of CLL, possi...

May 28th, 2022 - The prevalence of oropharyngeal squamous cell carcinoma has been increasing in North America due to human papillomavirus-associated disease. It is molecularly distinct and differs from other head and neck cancers due to the young population and high survival rate. The treatment regimens currently in place cause significant long-term toxicities. Studies have transitioned from mortality-based out...

May 28th, 2022 - The management of cholangiocarcinoma is continually reviewed on a current evidence basis to develop practice guidelines and consensus statements. However, the standardized treatment guidelines are still unclear for cholangiocarcinoma patients who are listed for liver transplantation. We aimed to validate and evaluate the potential efficacy of chemotherapy combination of Gemcitabine and Cisplati...

May 28th, 2022 - To determine the risk of mortality and factors associated with survival amongst patients diagnosed with primary hepatic angiosarcoma (PHA). All patients diagnosed with hepatocellular carcinoma (HCC) or PHA from 2004 to 2014 were identified from the National Cancer Database (NCDB). Further analysis was performed within the cohort of patients with PHA to assess the impact of surgery, chemotherapy...

May 28th, 2022 - Up to 20% of women diagnosed with tubo-ovarian carcinoma carry a germline pathogenic variant in a cancer-predisposing gene (e.g., BRCA1/BRCA2). Identifying these variants can help to inform eligibility for therapies, guide surveillance and prevention of new primary cancers, and assess risk to family members. The Gynecologic Oncology-Initiated Genetic Testing Model (GOIGT) was initiated at the M...

May 28th, 2022 - Although laser vaporization is a popular minimally invasive treatment for cervical intraepithelial neoplasia (CIN), factors influencing CIN recurrence are understudied. Moreover, the effect of surgeon volume on patients' prognosis after laser vaporization for CIN is unknown. This single-center retrospective study evaluated the predictive value of surgeon volume and patient characteristics for l...

May 28th, 2022 - We investigated whether in human head and neck squamous cell carcinoma (HNSCC) high levels of expression of stress keratin 17 (K17) are associated with poor survival and resistance to immunotherapy. We investigated the role of K17 in regulating both the tumor microenvironment and immune responsiveness of HNSCC using a syngeneic mouse HNSCC model, MOC2. MOC2 gives rise to immunologically cold tu...

May 28th, 2022 - Nucleophosmin 1 (NPM1, also known as B23) is a multifunctional protein involved in a variety of cellular processes, including ribosomal maturation, centrosome replication, maintenance of genomic stability, cell cycle control, and apoptosis. NPM1 is the most commonly mutated gene in adult acute myeloid leukemia (AML) and is present in approximately 40% of all AML cases. The underlying mechanisms...

May 28th, 2022 - Generalized myasthenia gravis (gMG) is a disease resulting from impaired neuromuscular transmission due to presence of antibodies that block acetylcholine receptors. Autoantibodies to acetylcholine receptors directly impair the activity of ion channels that conduct nerve impulses, and cross-link acetylcholine receptors resulting in complement-mediated destruction, further worsening functional i...

May 28th, 2022 - Objectives: Allogeneic hematopoietic stem cell transplantation (allo-HCT) is the only curative treatment for myelodysplastic syndromes (MDS), although predicting post-transplant outcomes remains inconclusive. This study evaluated patients who underwent allo-HCT for MDS to identify prognostic factors and develop a clinical risk model.Methods: We evaluated 55 patients between June 2000 and March ...

May 28th, 2022 - Gut dysbiosis has long been associated with the development of Crohn's disease and other gastrointestinal disorders. Otake-Kasamoto et al. (2022. J. Exp. Med.https://doi.org/10.1084/jem.20211291) report that dysbiotic microbiota-derived bioactive lipids, lysophosphatidylserines, can promote pathological Th1 cell responses through inducing metabolic reprogramming and epigenetic changes.

May 28th, 2022 - Studies describing longer-term outcomes after EEN induction are limited. We describe clinical outcomes during 90:10 EN induction, and 6- and 12- month outcomes among patients that successfully completed EN induction and then continued either EN or immunomodulator (IM) maintenance therapy. All children with CD treated with 90:10 EN induction protocol (90% formula:10% regular diet) at our IBD Cen...

May 28th, 2022 - The mechanisms underlying tumor immunosurveillance and their association with the immune-related adverse events (irAEs) associated with checkpoint inhibitor immunotherapies remain poorly understood. We describe a metastatic melanoma patient exhibiting multiple episodes of spontaneous disease regression followed by the development of several irAEs during the course of anti-programmed cell death ...

May 28th, 2022 - Acute myeloid leukemia (AML) with inv(16)/t(16;16) is among the most frequent AML subtypes. It is recognized by the detection of the CBFB-MYH11 fusion which confers a favorable prognosis, irrespective of the presence of secondary cytogenetic abnormalities. However, the effect of additional genetic anomalies on the behavior of inv(16) AML is debatable. Recent case reports describe an unfavorable...

May 28th, 2022 - The effects of specific body mass index (BMI) category and sarcopenia within each BMI category on outcomes in patients undergoing esophageal surgery with esophageal squamous cell carcinoma have not been thoroughly examined. This study included 1141 patients. Sarcopenia was determined with a total psoas muscle cross-sectional area at the level of the third lumbar vertebra in computed tomography....

May 28th, 2022 - A 23-year-old woman presented with a dry cough and dyspnea. Contrast-enhanced CT revealed an intratracheal space-occupying lesion with continuous homogeneous enhancement and airway stenosis. The patient then underwent 68Ga-DOTA-FAPI-04 PET/CT, which showed increased uptake of FAPI-04 by the lesion. Postoperative pathology confirmed the lesion as tracheal mucoepidermoid carcinoma. This case repo...

May 28th, 2022 - A 71-year-old man presented with chronic anemia (hemoglobin 7.3 g/dL). Further serum analyses showed elevated prostate-specific antigen (13 ng/mL), suggestive of prostate cancer. However, ultrasound-guided transrectal sextant biopsy did not find any evidence of prostate cancer. In order to improve guidance of intended repeated biopsy, [18F]prostate-specific membrane antigen (PSMA) 1007 PET/CT w...
