Common Signs and Symptoms of Prostate Squamous Cell Carcinoma

Prostate squamous cell carcinoma, a rare and aggressive type of prostate cancer, can exhibit various signs and symptoms, particularly in its advanced stages. While early-stage prostate cancer often shows no symptoms or signs, the following are some common indicators of this condition:

• Lower urinary tract symptoms (LUTS): These include obstructive symptoms such as straining, weak stream, and hesitancy, which can be caused by a tumor pressing on the bladder and urethra [4].
• Frequent urination: A tumor on the prostate can put pressure on your bladder and urethra, leading to a frequent and sometimes urgent need to urinate, especially at night [13].
• Pain or burning with urination or ejaculation: These symptoms are often associated with advanced prostate cancer, including squamous cell carcinoma [3].
• Blood in the urine (hematuria): This can be a sign of prostate cancer, particularly if it's accompanied by other symptoms like pain or difficulty starting to urinate [5].
• Bone pain: As prostate cancer spreads to bones, it can cause pain and discomfort in various parts of the body [10].

Diagnostic Tests for Prostate Squamous Cell Carcinoma

Prostate squamous cell carcinoma is a rare and aggressive form of cancer that affects the prostate gland. Diagnosing this condition can be challenging, but several diagnostic tests can help identify it.

• Biopsy: A biopsy is a diagnostic test that involves removing a small sample of tissue from the prostate gland for examination under a microscope. This test can usually be performed during a short office visit, and the results are often provided within a few days [1].
• Digital Rectal Examination (DRE): A DRE is a physical exam where a doctor inserts a gloved finger into the rectum to feel the prostate gland for any abnormalities. While not definitive on its own, an abnormal DRE can suggest the presence of prostate squamous cell carcinoma [8].
• Prostate-Specific Antigen (PSA) Test: A PSA test measures the level of PSA in the blood, which can be elevated in men with prostate cancer, including squamous cell carcinoma. However, this test is not specific to squamous cell carcinoma and can have false positives or negatives [7][8].
• Transrectal Ultrasound-Guided Biopsy: This diagnostic test uses sound waves to create images of the prostate gland, which helps guide a biopsy needle to collect tissue samples for examination [4].
• Immunohistochemical (IHC) Stains: IHC stains can help identify the type of prostate cancer by analyzing the expression of specific proteins on the surface of cancer cells. This test may be ordered in addition to a biopsy to confirm the diagnosis [10].

[3] Fine needle aspiration (FNA) is another diagnostic option, but it's not specifically mentioned for prostate squamous cell carcinoma. [4] Diagnosis is suggested by digital rectal examination (DRE) or PSA measurement and confirmed by transrectal ultrasound-guided biopsy.

[6] Squamous cell carcinoma of the prostate is a rare tumor, making up 0.5% to 1% of all prostate carcinomas. [7] Like common prostate cancer, mucinous prostate cancer can cause the levels of PSA in the blood to rise. [8] Prostate cancer can be detected early by checking the blood level of prostate-specific antigen (PSA) in blood. [9] Multiparametric MRI is recommended as the initial diagnostic test for suspected prostate cancer. Patients whose MRI results are highly suspicious may undergo a biopsy. [10] A doctor may also order additional tests such as immunohistochemical (IHC) stains to help identify the type of prostate cancer.

Treatment Options for Prostate Squamous Cell Carcinoma

Prostate squamous cell carcinoma (SCC) is a rare and aggressive form of cancer, making up only 0.5% to 1% of all prostate carcinomas. Due to its rarity, there is limited information on clinical presentation, diagnostic workup, treatment, and prognosis.

Chemotherapy

Chemotherapy is one of the treatment options for metastatic squamous carcinoma of the prostate. The chemo drugs most often used to treat SCC include cisplatin, carboplatin, 5-fluorouracil (5-FU), and paclitaxel [3][6]. These drugs work in different ways to stop the growth of tumor cells, either by killing the cells or stopping them from dividing [5].

Targeted Therapy

Drugs that target the EGFR protein, such as cetuximab (Erbitux), have been shown to shrink some SCCs in early studies [6]. Although the evidence for their effectiveness is limited, targeted therapy may be considered as part of a multifaceted approach to treatment.

Multifaceted Approach

For those diagnosed with prostate squamous cell carcinoma, doctors may recommend a multifaceted approach to treatment, including chemotherapy, radiation therapy, and other modalities [8]. This comprehensive approach aims to address the cancer from multiple angles and improve patient outcomes.

Expanded Access

In cases where no comparable or satisfactory alternative therapy options are available, Expanded Access may be considered as a potential pathway for patients with serious or immediately life-threatening diseases, including prostate squamous cell carcinoma [10].

It's essential to note that treatment decisions should be made in consultation with a healthcare professional, taking into account individual patient factors and the latest medical research.

The differential diagnosis for prostate squamous cell carcinoma (SCC) involves considering various conditions that can present with similar symptoms and characteristics. Based on the search results, here are some key points to consider:

• Adenocarcinoma: This is the most common type of prostate cancer, and it's possible for SCC to be a variant or a component of adenocarcinoma [6].
• Squamous metaplasia: This is a change in the prostate tissue that can occur due to hormonal therapy or prostatic infarction, which can mimic SCC [4].
• Adenosquamous carcinoma: This type of cancer combines both glandular and squamous cell components, making it difficult to distinguish from SCC [6].
• Urothelial carcinoma with squamous differentiation: This is a rare type of cancer that can involve the prostate, and its differential diagnosis includes SCC [14].
• Squamous metaplasia of the prostate: This is a condition where there's an abnormal growth of squamous cells in the prostate, which can be mistaken for SCC [4].

It's essential to note that the differential diagnosis for prostate SCC is broad, and it requires careful consideration of various factors, including clinical presentation, histopathology, and molecular characteristics.
