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).
A baby's chances for survival increases 3 to 4 percentage points per day between 23 and 24 weeks of gestation, and about 2 to 3 percentage points per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [ 16 ]
Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy.IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [5]
At early presentation of pregnancy at around 6 weeks, early dating ultrasound scan may be offered to help confirm the gestational age of the embryo and check for a single or twin pregnancy, but such a scan is unable to detect common abnormalities. Details of prenatal screening and testing options may be provided.
Normal weight at term delivery is 2,500–4,200 g (5 lb 8 oz – 9 lb 4 oz). [citation needed] SGA is not a synonym of low birth weight, very low birth weight, or extremely low birth weight. For example, with a 35-week gestational age delivery, a weight of 2,250 g (4 lb 15 oz) is appropriate for gestational age but is still low birth weight.
FIGO modified Prognostic Scoring System. The system evaluates the patients to those with GTN as low-risk and high-risk based on several risk factors such as age, pregnancy or interval of pregnancies, size or metastases of tumor and prior chemotherapy. Each risk factors are rated at levels 0-4 scores.
The World Health Organization defines perinatal mortality as the "number of stillbirths and deaths in the first week of life per 1,000 total births, the perinatal period commences at 22 completed weeks (154 days) of gestation, [3] and ends seven completed days after birth", [4] but other definitions have been used.
The survival rate following treatment with chemotherapy is approximately at least 90%. [4] If gestational choriocarcinoma has spread to the liver in an individual, survival rate may be lower. [7] Overall survival rate is also higher when management of gestational choriocarcinoma occurs in a setting with physicians familiar with the condition.
