Cancer-Critical Genes I: Proto-oncogenes

9.1K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

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,...

Area of Science:

  • Pathology
  • Oncology
  • Head and Neck Surgery

Background:

  • Salivary gland oncocytomas are uncommon neoplasms.
  • Characterized by polygonal cells with granular eosinophilic cytoplasm and uniform nuclei.
  • Generally benign with a low recurrence rate following complete surgical excision.

Purpose of the Study:

  • To discuss a classic example of a salivary gland oncocytoma.
  • To highlight the importance of identifying distinguishing features between oncocytomas and malignant mimics.
  • To emphasize the benign nature and low recurrence rate of oncocytomas.

Main Methods:

  • Histopathological examination of salivary gland neoplasms.
  • Review of clinical presentation and surgical outcomes.
  • Comparative analysis of benign oncocytomas and malignant variants.

Main Results:

  • Oncocytomas exhibit characteristic cellular morphology.
  • Malignant tumors can mimic oncocytomas histologically.
  • Complete surgical excision is associated with a low recurrence rate for oncocytomas.

Conclusions:

  • Salivary gland oncocytomas are benign tumors requiring accurate histological identification.
  • Awareness of differentiating features is essential to avoid misdiagnosis with malignant counterparts.
  • Surgical management ensures favorable prognosis with minimal recurrence.
