Abstract

Insights

Robot-assisted surgery for benign sacral tumors offers precise dissection and minimal blood loss. This minimally invasive approach is technically feasible, leading to shorter hospital stays and no recurrences in a small patient cohort.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics
  • Oncology

Background:

  • Limited research exists on robot-assisted sacral surgery.
  • This study evaluates outcomes for benign sacral/presacral tumors using robotic assistance.

Purpose of the Study:

  • To assess the efficacy and safety of robot-assisted minimally invasive sacral surgery.
  • To evaluate outcomes in patients with benign sacral or presacral tumors.

Main Methods:

  • Retrospective study of seven patients with benign sacral/presacral tumors.
  • Procedures performed between June 2015 and June 2016 using the da Vinci Si HD robotic surgical system.
  • Transperitoneal resection was the primary surgical approach.

Main Results:

  • Mean patient age was 43.8 years; operation time varied (60-335 min).
  • Median blood loss was 52 ml for complete resections and 675 ml for combined approaches.
  • Histological diagnoses included schwannoma (5 cases), chordoma (1), and solitary fibroma (1). No complications or recurrences were observed during follow-up (24-31 months).

Conclusions:

  • Robot-assisted sacral surgery enables precise dissection with excellent visualization.
  • The procedure is technically feasible, associated with minimal blood loss, fewer injuries, and short hospitalization.
  • This approach is particularly beneficial for benign presacral tumors.

Tumor Immunotherapy01:27

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.

Tumor Progression02:07

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...

The Tumor Microenvironment02:17

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...

Matrix-Assisted Laser Desorption Ionization (MALDI)

Matrix-assisted laser desorption ionization (MALDI) is a powerful analytical technique used in mass spectrometry. It enables the identification and characterization of various biomolecules, including proteins, peptides, nucleic acids, and carbohydrates. MALDI is an ionization technique, widely employed in biological and medical research, as well as in fields like pharmacology and biochemistry.The analyte of interest, a biomolecule or a mixture of biomolecules, is mixed with a suitable matrix...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

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...
