Summary
Malignant prolactinoma, a rare invasive pituitary tumor, is diagnosed by metastasis, not histology. Bromocriptine offers palliative care for these aggressive adenomas.
Area of Science:
- Endocrinology
- Oncology
- Neurosurgery
Background:
- Malignant prolactinoma is a rare, aggressive tumor arising from pituitary adenomas.
- Distinguishing malignant from benign prolactinoma is challenging, often requiring evidence of metastasis.
Observation:
- This study presents two new cases of malignant prolactinoma and reviews existing literature.
- Cases often develop from known, particularly invasive, pituitary adenomas.
Findings:
- Diagnosis of malignant prolactinoma relies on detecting metastasis, not solely on histological examination.
- Bromocriptine demonstrates utility as a palliative treatment option.
Implications:
- Understanding the diagnostic criteria and treatment options for malignant prolactinoma is crucial for patient management.
- Further research into the pathogenesis and targeted therapies for this rare malignancy is warranted.

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
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...

mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
