Tumor Immunotherapy01:27

Tumor Immunotherapy

1.9K
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.

Tumor Progression02:07

Tumor Progression

7.4K
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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.8K
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...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

6.1K
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.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Summary
This summary is machine-generated.

Anterior knee pain can signal rare patella tumors, often misdiagnosed. Treatment strategies for patella tumors vary based on tumor type and stage, ranging from curettage to patellectomy or amputation.

Area of Science:

  • Orthopedic Surgery
  • Musculoskeletal Oncology
  • Diagnostic Imaging

Background:

  • Anterior knee pain is commonly attributed to patella chondromalacia.
  • However, patella tumors, though rare, can also present as anterior knee pain.
  • These tumors are frequently misdiagnosed as benign lesions.

Purpose of the Study:

  • To differentiate patella tumors from other knee conditions.
  • To outline diagnostic features and staging of patella tumors.
  • To present surgical treatment guidelines based on tumor type and stage.

Main Methods:

  • Radiographic analysis including margin, cortical involvement, trabecular pattern, and matrix type.
  • Staging using bone scans, computed tomography (CT), and magnetic resonance imaging (MRI).
  • Review of treatment outcomes based on tumor stage and characteristics.

Main Results:

  • Benign patella tumors (73%) are more common than malignant tumors (27%).
  • Giant cell tumor and chondroblastoma are the most frequent benign neoplasms.
  • Treatment varied from curettage for early-stage benign lesions to patellectomy or amputation for advanced or malignant tumors.

Conclusions:

  • Accurate radiographic assessment is crucial for diagnosing patella tumors.
  • Surgical management of patella tumors requires careful consideration of staging and tumor type.
  • Timely and appropriate surgical intervention is essential for optimal patient outcomes.
