Histopathologic prognosis of thymomas: another example of medical surrogacy.
Particularly in anatomic pathology, the past 2 decades have witnessed a proliferation of tests that are surrogates for selected analytes of predictive or prognostic interest. Those targets include such moieties as functional hormone receptor proteins and the composition of genes that govern responses to selected growth factors. Common respective examples of those groups are estrogen and progest...
متن کاملProteomic Signatures of Thymomas
Based on the histological features and outcome, the current WHO classification separates thymomas into A, AB, B1, B2 and B3 subtypes. It is hypothesized that the type A thymomas are derived from the thymic medulla while the type B thymomas are derived from the cortex. Due to occasional histological overlap between the tumor subtypes creating difficulties in their separation, the aim of this stu...
متن کاملThymomas: a continuing challenge.
Thymic epithelial tumors usually are broadly classified into two main categories: thymoma and thymic carcinoma. In adults, thymomas are the most common primary tumor in the anterior mediastinum.[2] A large variety of paraneoplastic or parathymic syndromes may suggest the presence of a thymoma.[3] Myasthenia gravis coexists in approximately 30% to 40% of patients with thymoma.[4] It is still unc...
متن کاملThymomas: clinical-pathological correlations.
AIM Since World Health Organization (WHO) histologic typing of tumors of the thymus publication in 1999 only a few studies correlated this classification with the clinical features of the patients. We present the results of a retrospective analysis on patients, operated on for a thymoma, whose specimens were available, to compare the WHO thymoma histologic classification to the clinical behavio...
متن کاملTransferrin receptor expression in adenocarcinoma of the lung as a histopathologic indicator of prognosis.
Immunohistochemical reactivity with OKT9 (antitransferrin receptor) monoclonal antibody was studied in 58 surgically resected adenocarcinomas of the lung. The cell surface and cytoplasm of the tumor cells were stained in 44 cases (76 percent). The expression of the transferrin receptor (TrfR) in tumor cells was compared with histopathologic prognostic factors, such as TNM factors, degree of his...
