[Metastasis of prostatic cancer (based on lymphographic data)]

Area of Science:

• Urology
• Oncology
• Radiology

Background:

• Prostatic carcinoma is a significant health concern.
• Understanding the spread of cancer (metastasis) is crucial for treatment.
• Lymphatic system involvement is a common pathway for cancer spread.

Purpose of the Study:

• To determine the incidence of lymphogenous metastases in prostatic carcinoma.
• To correlate metastasis incidence with tumor stage.
• To identify the primary sites of metastasis and discuss lymphography indications.

Main Methods:

• Lymphographic examination was performed on 56 patients with prostatic carcinoma.
• Patients were categorized by tumor stage (I-IV).
• Metastasis presence and location were recorded.

Main Results:

• No lymphogenous metastases were found in Stage I prostatic carcinoma.
• Metastases were detected in 3/16 (Stage II), 4/12 (Stage III), and 13/21 (Stage IV) patients.
• The iliac lymph nodes were the most common site for metastases.

Conclusions:

• Lymphogenous metastasis in prostatic carcinoma is stage-dependent.
• Lymphography is a valuable tool for assessing metastasis in advanced stages.
• Findings support tailored lymphographic examination based on tumor progression.
