Data on the radiological(ultrasonography and computer tomography scan) and/or histological response were too limited to draw any conclusions. Further randomised placebo-controlled trials are necessary.
They grouped 10,283 ovarian cancer cases- about half with one type of tumour, called serous- by the four major histological subtypes, and identified two new genomic regions associated with serous ovarian cancer.
Age-standardized incidence rates(ASR) and average annual percent changes(APCs) in the incidence rates were calculated by histological subtype and tumor location.
The dermatologic eruptions consist of follicular papules and/ or hardened plaques that lead to distinct histological changes in the hair follicles, resulting in hair loss.
In the absence of the effect of the drug on the 14th day(incomplete abortion, ongoing pregnancy) conducted vacuum aspiration with subsequent histological examination of aspirate.
Other histologic and immunohistochemical features, such as the degree of apparent cellular transformation along identifiable cell lineages(ependymal, glial, etc.), can be used to separate these tumors to some degree.
Histologic features such as folliculotropism or large-cell transformation(>25% large cells), CD30+ or CD30-, and clinical features, such as ulceration, are important to document.
Chemotherapy after surgery was tailored according to histologic response. Four-year EFS was 84.1% for FH tumors, 58.2% for anaplastic-histology tumors, and 82% for blastemal-type tumors.
Melanomas of the posterior uveal tract generally have a more malignant, histologic appearance; are detected later; and metastasize more frequently than iris melanomas.
Although cell type is not known to be of prognostic significance, histologic cell types include chief cell, transitional clear cell, and mixed cell types.
Histologic study: A laboratory test in which stains are added to a sample of cancer cells or tissue and viewed under a microscope to look for certain changes in the cells.
The largest cluster, which comprised 64% of the samples, had classical histologic features of olfactory neuroblastoma and 10% had recurrent DNMT3A and TP53 mutations.
While associations between histologic features and prognosis or responsiveness to therapy have been suggested, with the exception of anaplasia, none of these features have reached statistical significance in North American treatment algorithms, and therefore, do not direct the initial therapy.[143].
The most common types of NSCLC are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma, but there are several other types that occur less frequently, and all types can occur in unusual histologic variants.
The Children's Hepatic tumor International Collaboration(CHIC) analyzed survival in a collaborative database of 1,605 patients with hepatoblastoma treated on eight separate multicenter clinical trials, with central review of all tumor imaging and histologic details.
A myxopapillary ependymoma arises almost exclusively in the location of the conus medullaris, cauda equina, and filum terminale of the spinal cord and is characterized histologically by tumor cells arranged in a papillary manner around vascularized myxoid stromal cores.
Hodgkin lymphoma can be segregated into the following three age cohorts because of the variation in etiologies and histological subtypes(refer to Table 1): Children: Individuals aged 14 years and younger have a higher prevalence of nodular lymphocyte-predominant disease and Epstein-Barr virus(EBV)-associated mixed-cellularity disease.
