Insights

Pediatric patients with mature ovarian teratoma have a significant risk of developing a metachronous contralateral ovarian tumor. Yearly ultrasounds are recommended for early detection and fertility preservation.

Area of Science:

  • Gynecology
  • Pediatric Oncology

Background:

  • Mature ovarian teratomas are common germ cell tumors in pediatric patients.
  • Risk of contralateral ovarian tumor development requires further investigation.

Purpose of the Study:

  • To assess the incidence and risk of metachronous ovarian tumors in pediatric patients previously treated for mature ovarian teratoma.

Main Methods:

  • Retrospective analysis of 22 pediatric patients who underwent oophorectomy for mature teratoma between 1981 and 2011.
  • Median follow-up duration of 4.4 years.

Main Results:

  • 23% of patients developed a metachronous contralateral ovarian tumor during follow-up.
  • Kaplan-Meier analysis indicated a 14% ± 8% risk of contralateral tumor within five years and 66% ± 26% within 10 years.
  • Metachronous tumors included mature teratomas and seromucinous infantile cystadenomas; all treated with ovary-preserving surgery.

Conclusions:

  • A substantial proportion of pediatric patients with ovarian mature teratoma develop metachronous contralateral tumors.
  • Yearly ultrasound surveillance is crucial for early diagnosis, enabling fertility-sparing management.

Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Oogenesis01:22

Oogenesis

Oogenesis,  the process of developing egg cells (female gametes), occurs within the ovaries and is fundamental to female fertility. This sequence begins during fetal development when diploid oogonia in the developing ovaries undergo mitotic divisions to produce primary oocytes. By birth, these primary oocytes enter prophase I of meiosis but become arrested in this stage, remaining suspended until puberty.
Each primary oocyte is surrounded by a layer of pre-granulosa cells, forming what is...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Ovarian Cycle01:27

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
