Summary
Advances in vulvar squamous cell carcinoma (VSCC) care include refined tumor classification and surgical strategies. Pathologists play a key role in subtyping, prognostication, and recognizing precursors for better patient outcomes.
Area of Science:
- Oncology
- Pathology
- Gynecologic Oncology
Background:
- Vulvar squamous cell carcinoma (VSCC) is rare, but significant clinical care improvements have emerged.
- Progress includes advancements in tumor classification, surgical techniques, precursor detection, and targeted therapies.
Purpose of the Study:
- To review key evolutionary changes in VSCC care.
- To emphasize the evolving role of pathologists in VSCC management.
- To inform future strategies for optimizing patient outcomes.
Main Methods:
- Review of recent literature and clinical practice changes in VSCC.
- Analysis of histopathologic and molecular classification refinements.
- Focus on pathologist responsibilities in subtyping, prognostication, and precursor recognition.
Main Results:
- Enhanced diagnostic precision through refined classification.
- Improved prognostication and personalized therapeutic decisions.
- Identification of VSCC precursors enabling earlier intervention.
Conclusions:
- Pathologists are crucial for VSCC tumor subtyping (HPV, p53 status), prognostication, and margin evaluation.
- Standardizing precursor terminology, especially for HPV-independent p53 wild-type lesions, is important.
- Continued progress is needed to further optimize patient outcomes and the standard of care for VSCC.

02:07Tumor 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...

01:30Skin Cancer
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.

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
