Base Excision Repair01:54

Base Excision Repair

21.8K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Skin Cancer

3.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Summary
This summary is machine-generated.

Unplanned excision of soft tissue sarcoma (STS) can be avoided with better surgeon education. Re-excision after unplanned excision does not increase recurrence rates but is less ideal for patients than planned excision.

Area of Science:

  • Oncology
  • Surgical Pathology
  • Radiology

Background:

  • Soft tissue sarcoma (STS) is rare and heterogeneous, often missed in differential diagnoses for lumps.
  • Unplanned excisions (UE) frequently occur in non-specialized centers.
  • Postoperative MRI can be challenging to interpret due to edema, hematoma, and seroma, complicating differentiation between residual tumor and surgical changes.

Purpose of the Study:

  • To evaluate the outcomes of re-excision (RE) after unplanned excision (UE) for soft tissue sarcoma.
  • To compare re-excision outcomes with planned excision (PE).
  • To highlight the patient and clinical implications of UE followed by RE versus PE.

Main Methods:

  • Propensity score matching analysis was used to compare patient outcomes.
  • Outcomes analyzed included mortality and local recurrence rates.
  • Surgical approach (PE vs. UE followed by RE) was the primary comparison factor.

Main Results:

  • Patients undergoing RE after UE did not exhibit higher mortality or local recurrence rates compared to those with PE.
  • Re-excision procedures often necessitate complex reconstruction.
  • Planned excision is preferable for patients, minimizing hospital stays and time off work.

Conclusions:

  • Re-excision following unplanned excision of soft tissue sarcoma is oncologically similar to planned excision in terms of recurrence and mortality.
  • Minimizing unplanned excisions through continuous surgeon education is crucial.
  • Optimizing surgical planning and execution for soft tissue sarcoma is essential for improved patient outcomes and resource utilization.
