Carcinoembryonic antigen: its role in malignant extraintestinal neoplasms

Journal of Chemotherapy, 1997
Carcinoembryonic radioimmunological research has attracted the attention of researchers, clinicians and oncologists for a number of years 1. However, its validity in the early diagnosis and the follow-up of a variety of cancers is still a subject of controversy.

Five novel cell surface antigens of CNS neoplasms

Journal of the Neurological Sciences, 1989
Optimal monoclonal antibody-mediated immunotherapy requires the identification of tumor-restricted cell surface antigens. We have identified and partially characterized 5 new monoclonal antibodies generated against malignant astrocytoma, medulloblastoma, neuroblastoma and melanoma which were used to define 5 neuroectodermal tumor antigenic systems.

Preferentially Expressed Antigen in Melanoma Immunostaining in a Series of Melanocytic Neoplasms

The American Journal of Dermatopathology, 2021
Abstract: In their 2018 article, Lezcano et al [AJSP 2018(11):1456] show that diffuse tumor cell nuclear reactivity for Preferentially expressed Antigen in Melanoma (PRAME) is a feature of melanoma and that benign and atypical melanocytic tumors are PRAME negative or show only focal positivity for PRAME.

Immunohistochemical demonstration of carcinoembryonic antigen and related antigens in various cutaneous keratinous neoplasms and verruca vulgaris

British Journal of Dermatology, 1998
Carcinoembryonic antigen (CEA), which is a well-known marker for the normal sweat gland apparatus and its neoplasms in the skin, was recently demonstrated in sebaceous neoplasms. The aim of this study was to examine the expression of CEA and related antigens in the other cutaneous keratinous neoplasms and verruca vulgaris.

Flow Cytometric DNA and Nuclear Antigen Content in Astrocytic Neoplasms

American Journal of Clinical Pathology, 1988
Simultaneous flow cytometric DNA content and proliferation-associated nuclear antigen (p105) quantitation was performed on 23 astrocytic tumors and the results correlated with histologic subtype. Three of nine anaplastic astrocytomas and one of ten glioblastomas had an identifiable aneuploid peak, while all four well differentiated astrocytomas were ...

Characterization of renal neoplasms with monoclonal antibodies to leukocyte differentiation antigens

Cancer, 1986
Several monoclonal antibodies against human leukocyte differentiation antigens have been shown to react with normal kidney. Four monoclonal antibodies with different patterns of reactivity on normal kidney were tested against 20 renal epithelial neoplasms and 5 Wilms' tumors.

Failure to demonstrate papovavirus tumor antigen in human cerebral neoplasms

Annals of Neurology, 1978
AbstractCell cultures derived from 80 brain tumors failed to show the intranuclear tumor (T) antigen common to cells transformed by simian virus 40 (SV40) or BK or JC viruses.

Urine excretion of tumor-associated antigens by patients with gynecologic neoplasms

Gynecologic Oncology, 1980
Abstract Twenty-four-hour urine samples from known gynecologic cancer patients and normal donors were tested for antigen by a complement fixation assay using autologous sera as antibody sources. Eleven of fourteen cancer patients (78.6%) were antigenically positive while only 1 of 9 (11.1%) normal donors was positive.

Immunohistochemical Study of Carcinoembryonic Antigen in Mucinous Cystic Neoplasm of the Pancreas

European Surgical Research, 1992
Pathologic and immunohistochemical studies of 13 patients with mucinous cystic neoplasm of the pancreas were performed in order to determine whether these lesions represent overt or latent malignancy. In 9 patients with mucinous cystadenoma, the foci of mucus-rich columnar epithelia formed the usual pattern of stratifications and papillary projections ...

Antigens of experimentally-induced neoplasms: a conspectus

1978
Of the molecular changes associated with neoplastic transformation, the expression of tumour antigens has been the subject of special interest in recent years largely on account of the immunotherapeutic and diagnostic possibilities which their existence appears to raise1,2.
