The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Progression

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...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

mTOR Signaling and Cancer Progression

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.
The mTOR pathway or the...

Area of Science:

Ophthalmology
Radiology
Ophthalmic Pathology

Background:

A 61-year-old male with a history of diabetes and hypertension presented with unilateral proptosis and diplopia.
Symptoms included left eye pain, redness, and slowly progressive proptosis over six months, with restricted eye movements.
No vision loss or purulent discharge was noted, and systemic health markers were within normal limits.

Purpose of the Study:

To investigate the cause of unilateral proptosis and diplopia in a patient with no prior ophthalmologic history.
To utilize advanced imaging techniques for accurate diagnosis and characterization of orbital abnormalities.

Main Methods:

Clinical examination including visual acuity, ocular motility assessment, and ophthalmoscopy.
Laboratory investigations including complete blood cell count, liver and kidney function tests, erythrocyte sedimentation rate, C-reactive protein, and thyroid function tests.
Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) of the orbits with and without contrast enhancement.

Main Results:

Clinical findings revealed left eye proptosis, conjunctival edema, redness, and restricted medial and downward gaze.
Ophthalmoscopic examination showed unremarkable retina and retinal vascularity.
Systemic laboratory tests and thyroid function were normal, ruling out common systemic causes.

Conclusions:

Advanced orbital imaging (CT and MRI) is crucial for diagnosing the etiology of unilateral proptosis and diplopia.
The diagnostic pathway involved a combination of clinical assessment, laboratory workup, and detailed orbital imaging.
Further evaluation and management strategies would be based on the specific findings from the CT and MRI scans.
