Squamous Cell Carcinoma

---

Summary

Squamous Cell Carcinoma (SCC) of the prostate is a rare and aggressive type of prostate cancer. Unlike the more common adenocarcinoma of the prostate, SCC is characterized by its origin in the squamous cells, which are flat cells that may be found lining the prostate. This type of carcinoma falls under the histological classification of carcinoma, indicating its origin from epithelial cells.

Symptoms

The symptoms of Squamous Cell Carcinoma of the prostate can overlap with other types of prostate cancer but may include:

• Difficulty urinating or changes in urinary habits
• Blood in urine or semen
• Painful ejaculation
• Persistent pain in the lower back, hips, or pelvis
• Unexplained weight loss
• Fatigue

Since SCC is aggressive, symptoms may progress more quickly compared to other prostate cancers.

Treatments

The treatment options for Squamous Cell Carcinoma of the prostate are more limited compared to adenocarcinoma due to its rarity and aggressive nature. Standard treatments may include:

Surgery

• Radical Prostatectomy: Complete removal of the prostate. This is often recommended if the cancer is localized.

Radiation Therapy

• External Beam Radiation Therapy (EBRT): High-energy rays are used to target and kill cancer cells.

Chemotherapy

• Due to its aggressive nature, chemotherapy might be used, although its effectiveness can be limited.

The efficacy of these treatments can vary significantly, and SCC often has a poorer prognosis compared to other prostate cancers.

Experimental Treatments

Given the aggressive nature of SCC, experimental treatments are always being explored:

Immunotherapy

• Checkpoint Inhibitors: Drugs that help the immune system recognize and attack cancer cells. Their efficacy in SCC of the prostate is still under investigation.

Targeted Therapy

• EGFR Inhibitors: As some squamous cell carcinomas overexpress the epidermal growth factor receptor (EGFR), drugs targeting this receptor are being studied.

Clinical Trials

• Patients are encouraged to participate in clinical trials that explore new drug combinations or novel therapeutic approaches.

Side Effects of Treatments

The side effects of treatments for SCC of the prostate can vary depending on the modality used:

Surgery

• Incontinence
• Erectile dysfunction
• Risk of infection

Radiation Therapy

• Fatigue
• Skin irritation at the treatment site
• Urinary and bowel issues

Chemotherapy

• Nausea and vomiting
• Hair loss
• Increased risk of infection
• Fatigue

Immunotherapy and Targeted Therapy

• Autoimmune reactions
• Skin rashes
• Diarrhea

Modernity of Treatments

Many of the standard treatments have been in use for several decades, with radiation and surgery being established practices since the mid-20th century. However, chemotherapy protocols and their combinations are continually evolving, with new drugs and regimens being tested regularly.

Immunotherapy and targeted therapies are more recent developments in cancer treatment. Checkpoint inhibitors, for example, have been gaining traction in various cancers since the early 2010s, with ongoing research into their application for prostate cancers.

Clinical trials are continuously underway, and advancements in genetic and molecular profiling are paving the way for more personalized treatment approaches, even for rare cancers like SCC of the prostate. It's important for patients and healthcare providers to stay informed about the latest research and treatment options.
