Histopathology of high-grade prostatic intraepithelial neoplasia (HGPIN) with typical features, H&E stain. [6] High-grade prostatic intraepithelial neoplasia. HGPIN typically has one of four different histologic patterns: [2] tufted (fascicular patterning) micropapillary, cribriform and, flat. Its cytologic features are that of prostatic ...
This recognizes that prostatic carcinomas have multiple patterns and that prognosis is more accurately determined by adding the scores of the two most prevalent patterns. Using this system, the grades of the most prevalent and second most prevalent patterns (if at least 5% of the total), are added together to yield the overall Gleason score.
However, high magnification (right image) shows the key feature of prominent nucleoli (visible at 200x magnification to make the diagnosis of "high-grade"), as well as other typical features of HGPIN. Reference for features: - Margaret Sanders, M.B.B.Ch., Murali Varma, M.B.B.S.. High grade prostatic intraepithelial neoplasia (HGPIN).
Studies have shown Baux score to be effective in measuring comparative severity of burn injuries, and in predicting the prognosis for the patient. The modified version, which includes inhalation injuries, is more accurate than the original method, although neither method is as accurate as more complex calculated scores using advanced computer ...
The International Prognostic Index (IPI) is a clinical tool developed by oncologists to aid in predicting the prognosis of patients with aggressive non-Hodgkin's lymphoma. Previous to IPI's development, the primary consideration in assessing prognosis was the Ann Arbor stage alone, but this was increasingly found to be an inadequate means of ...
The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
Prognosis (Greek: πρόγνωσις "fore-knowing, foreseeing"; pl.: prognoses) is a medical term for predicting the likelihood or expected development of a disease, including whether the signs and symptoms will improve or worsen (and how quickly) or remain stable over time; expectations of quality of life, such as the ability to carry out daily activities; the potential for complications and ...
Five-year relative survival rates describe the percentage of patients with a disease alive five years after the disease is diagnosed, divided by the percentage of the general population of corresponding sex and age alive after five years. Typically, cancer five-year relative survival rates are well below 100%, reflecting excess mortality among ...
