High-grade prostatic intraepithelial neoplasia (HGPIN) is an abnormality of prostatic glands and believed to precede the development of prostate adenocarcinoma (the most common form of prostate cancer). [1] [2] It may be referred to simply as prostatic intraepithelial neoplasia (PIN).
The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy. A Gleason score is given to prostate cancer based upon its microscopic ...
Mitoses (also seen in for example high-grade prostatic intraepithelial neoplasia (HGPIN) and prostate inflammation). [4] Prominent nucleoli [4] Intraluminal eosinophilic secretion [4] Intraluminal blue mucin [4]
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).
The prognosis of diagnosed prostate cancer varies widely based on the cancer's grade and stage at the time of diagnosis; those with lower stage disease have vastly improved prognoses. Around 80% of prostate cancer diagnoses are in men whose cancer is still confined to the prostate.
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
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.
Several patient characteristics were analyzed to determine whether they were associated with differences in survival, and the factors that emerged as significant were, in addition to the Ann Arbor stage: age, elevated serum lactate dehydrogenase (LDH), performance status, and number of extranodal sites of disease.
