Choriocarcinoma of the placenta during pregnancy is preceded by: hydatidiform mole (50% of cases) spontaneous abortion (20% of cases) ectopic pregnancy (2% of cases) normal term pregnancy (20–30% of cases) hyperemesis gravidarum; Rarely, choriocarcinoma occurs in primary locations other than the placenta; very rarely, it occurs in testicles.
Treatment of testicular cancer is one of the success stories of modern medicine, with sustained response to treatment in more than 90% of cases, regardless of stage. [53] In 2011 overall cure rates of more than 95% were reported, and 80% for metastatic disease—the best response by any solid tumor, with improved survival being attributed ...
However, it is present as a component of almost ninety percent of mixed nonseminomatous germ cell tumours. The average age at diagnosis is 31 years, and typically presents as a testicular lump which may be painful. One-fifth to two-thirds of patients with tumours composed predominantly of embryonal carcinoma have metastases at diagnosis. [1]
The hCG test can be used to screen for uterus cancer, or a molar pregnancy, which is when there is abnormal placental growth in the uterus. [9] The hCG test can also be done after a miscarriage to ensure that a molar pregnancy is not present. In men, the hCG test can be used to screen for the presence of testicular cancer. [9]
It is the most common testicular tumor in children under three, [2] and is also known as infantile embryonal carcinoma. This age group has a very good prognosis. In contrast to the pure form typical of infants, adult endodermal sinus tumors are often found in combination with other kinds of germ cell tumor, particularly teratoma and embryonal ...
Previous testicular cancer; The diagnosis is confirmed in different ways. An ultrasound scan can be used to diagnose to a 90-95% accuracy. Bloods can also be taken to look for elevated tumour markers which is also used to analyse the patient's response to treatment. 80% of testicular cancer cases are from the 20-34 year old age range [18]
In humans, this group accounts for 8% of ovarian cancers and under 5% of testicular cancers. Their diagnosis is histological: only a biopsy of the tumour can make an exact diagnosis. They are often suspected of being malignant prior to operation, being solid ovarian tumours that tend to occur most commonly in post menopausal women.
OGCTs are commonly found during pregnancy when an adnexal mass is found during a pelvic examination, ultrasound scans show a solid mass in ovary or blood serum test shows elevated alpha-fetoprotein levels. [1] They are unlikely to have metastasized and therefore the standard tumor management is surgical resection, coupled with chemotherapy. [2]
