Spontaneous Regression of Blastic Plasmacytoid Dendritic Cell Neoplasm Following Sepsis by <i>Serratia marcescens</i>: A Case Report and Literature Review

Internal Medicine, 2021
Spontaneous regression is rare in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN). An 85-year-old man presented with pancytopenia and skin lesions, and the bone marrow exhibited 79.6% CD4+, CD56+, CD123+, and TCL-1+ abnormal cells ...

Acute regression of a melanocytic neoplasm [PDF]

Journal of Cutaneous Pathology, 2023
AbstractImmune‐mediated regression of melanocytic neoplasms is predominantly lymphocytic, driven by CD8+ anti‐tumoral T‐cells and, rarely, natural killer cells. Histopathologic features of regression include effacement of the epidermis, replacement of tumor cells by a fibrotic stroma, varying degrees of chronic inflammation (usually lymphocytes) and ...

Risk prediction for malignant intraductal papillary mucinous neoplasm of the pancreas: logistic regression versus machine learning [PDF]

Scientific Reports, 2020
AbstractMost models for predicting malignant pancreatic intraductal papillary mucinous neoplasms were developed based on logistic regression (LR) analysis. Our study aimed to develop risk prediction models using machine learning (ML) and LR techniques and compare their performances.

Apparent spontaneous regression of malignant neoplasms after radiography: Report of four cases

International Journal of Surgery Case Reports, 2016
On rare occasions, an apparently spontaneous regression of unknown etiology is observed in a neoplasm. We report a series of 4 patients with apparent spontaneous regression of malignant lymphomas after radiography.All four of the tumors were malignant lymphomas. The regressions occurred between 1 and 2 months after the radiographic examinations.

Outcomes of ovarian-sparing surgery in children with ovarian neoplasm: A meta-analysis and meta-regression [PDF]

, 2023
Abstract Objectives. Ovarian-sparing surgery (OSS) is increasingly used to treat various ovarian neoplasms (ON) in children. The feasibility and prognosis of OSS on ON are still being explored. The aim of this research was to demonstrate the clinical results of implementing OSS in children diagnosed with ON. Methods.

Delayed hypersensitivity-induced regression of human neoplasms [PDF]

Cancer, 1971
Delayed hypersensitivity reactions were induced over primary and metastatic tumors of the skin in patients with basal cell carcinoma, mycosis fungoides, lymphoma metastatic to the skin, and carcinoma of the breast metastatic to the skin. Patients were sensitized with 2000 μg dinitrochlorobenzene (DNCB), followed by local application of 100 μg DNCB over

Loss-of-function polymorphism in IL6R reduces risk of JAK2V617F somatic mutation and myeloproliferative neoplasm: A Mendelian randomization study

EClinicalMedicine, 2020
Background Whether inflammation is independently associated with development of JAK2V617F mutation and myeloproliferative neoplasm is not clear. We tested the hypothesis that a loss-of-function polymorphism in IL6R (marked by rs4537545) reduces risk of ...

Using Cox Regression to Forecast of Survival of Women with Multiple Malignant Neoplasms

Statistics of Ukraine, 2018
Recently, an increase in the incidence of multiple primary malignant neoplasms has been observed, specifically, when two or more unrelated tumors originate from different organs and appear in the body simultaneously or sequentially, one after another.

Adrenocortical adenomas with regression and myelolipomatous changes: urinary steroid profiling supports a distinctive benign neoplasm [PDF]

Clinical Endocrinology, 2014
SummaryBackgroundAdrenocortical neoplasms are classically divided into adenomas (ACA) and carcinomas (ACC). Heterogeneous appearance and greater size are criteria to suggest malignancy, along with the urinary steroid profile (USP). The presence of regression and myelolipomatous changes in adenomas (ACA‐RML) can contribute to confusion with ACC and its ...
