mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.8K
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.

Tumor Progression02:07

Tumor Progression

6.4K
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 Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.1K
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.
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:

  • Oncology
  • Radiotherapy
  • Nuclear Medicine

Background:

  • Oligometastatic prostate cancer with lymph node recurrence presents a unique clinical challenge.
  • This state is increasingly recognized due to advancements in imaging and radiotherapy.
  • Prostate-specific membrane antigen positron emission tomography (PSMA-PET) enhances detection accuracy.

Purpose of the Study:

  • To review the current evidence on image-guided stereotaxic body radiotherapy (SBRT) for nodal recurrence in prostate cancer.
  • To discuss areas of debate and future directions in this treatment approach.
  • To highlight the benefits of advanced imaging and precision radiotherapy in managing oligorecurrent disease.

Main Methods:

  • Review of existing literature on PSMA-PET imaging and SBRT for prostate cancer recurrence.
  • Analysis of treatment outcomes, toxicity, and patient tolerance.
  • Discussion of technological advancements enabling precise radiation delivery.

Main Results:

  • PSMA-PET offers superior sensitivity and specificity compared to conventional imaging for detecting nodal recurrence.
  • Stereotaxic body radiotherapy (SBRT) allows safe, high-dose radiation delivery with low toxicity.
  • This approach is associated with prolonged disease control and excellent survival rates.

Conclusions:

  • Image-guided SBRT represents a compelling strategy for managing nodal recurrence in oligometastatic prostate cancer.
  • This approach holds potential for improving clinical outcomes and patient survival.
  • Further research is warranted to optimize treatment protocols and expand its application.
