The difference was clear both considering the diverse categories of malignancies, primary tumors, lymph node and liver metastasis (Figure 1A), and the whole SI-NETs cohort of patients (Figure 1B).
Post-natal X-ray exposure was also linked with a small elevation in the risk of all cancers and the major categories of malignancies in children.
For example, in approaching to fever, the presence of bone pain and weight loss suggests category of malignancy, the presence of rash and arthritis suggests category of inflammatory diseases, and the history of exposure to febrile patients or recent traveling suggests category of infectious diseases [ 19].
Gleevec works against two types of cancer, both relatively rare, and is being tested for efficacy in a third and larger category of malignancies.
It would be interesting to investigate additional CUP specimens to know whether mutations of codon 181 occur at a relatively high frequency in this category of malignancies.
Different categories of secondary malignancies can occur after allo-HSCT, including post-transplant lymphoproliferative disorders, late relapse of the primary disease, donor-type secondary leukemia/other malignancy and de novo solid tumors.
The entire breast images, breast tissue or lesions were classified as per the following assessments: need additional imaging evaluation (category 0); negative (category 1); benign finding (category 2); probably benign finding with a recommendation for additional imaging or biopsy (category 3); suspicious (category 4); or highly suggestive of malignancy (category 5).
To determine the extent to which TSCs are a general component of primitive brain tumors, or are specific of certain tumor types, we performed a comparative study using a large sample of fifty-five pediatric brain tumors of various categories and grades of malignancy.
There is considerable heterogeneity among cases comprising individual histopathological categories of B cell malignancy, and in many instances heterogeneous class II phenotypes are also found on cells from the same tumour.
US-guided 14-gauge CNB was offered for suspicious lesions (Breast Imaging Reporting and Data System (BI-RADS) category 4) and lesions highly suggestive of malignancy (BI-RADS category 5) seen on US.
