What Is the Connection between Vasectomy and Cancer?

Spermatic cord tumors include various benign and malignant tumors that arise from the vas deferens, blood vessels, lymphatic vessels, connective tissue, adipose tissue, smooth muscle and nerve tissue. Among them, 70% are benign and mostly occur in the spermatic cord of the groin; 30% are malignant, and most of them are sarcomas, accounting for 91%, which often occur from the distal spermatic cord in the scrotum. Because the tumor infiltrates the surrounding tissues early, it is difficult to determine its exact location in clinical practice. Therefore, it is also known as "testicular tumor". 70% to 90% of the tumor near the testis occur on the spermatic cord, so the spermatic cord tumor is outside the testis. The most common tumor in the scrotum. Malignant tumors of spermatic cord account for about 30% of spermatic cord tumors, including rhabdomyosarcoma, malignant fibrous tissue tumor, liposarcoma, vas deferens, papillary cancer, fibrosarcoma and leiomyosarcoma. Among them, rhabdomyosarcoma is the most common and highly malignant. The malignancy of fibrosarcoma and leiomyosarcoma is relatively low.

Painless scrotal mass

Clinical manifestations of spermatic cord malignant tumors

Symptoms and signs

(1) Symptoms: Painless masses in the scrotum that grow faster; there are also those who suddenly increase in size based on the original mass.

(2) Swollen scrotum on the affected side of the body, which can be palpable and irregular, and sometimes has unclear boundaries with surrounding tissues. The light transmission test was negative.

2. Clinical stage 4

Phase I:

Stage Ia: The tumor is completely confined to the spermatic cord.

Stage Ib: The tumor has local infiltration but can be completely removed.

Phase II:

Stage a: The tumor remains under the microscope after tumor resection.

Stage b: regional lymph node metastasis but complete resection.

Stage : The tumor cannot be completely removed, and there are residual tumors.

Stage : There is distant metastasis.

Spermatic cord malignancy

B ultrasound and CT can determine whether the tumor envelope is intact, its relationship with surrounding tissues, and whether there is lymph node metastasis. Histopathological examination can clarify the nature of the tumor.

Diagnosis of spermatic cord malignancy

When it is found that the spermatic cord in the scrotum has a mass that is not related to the testicles, it should be taken seriously, and the right to treat the malignant tumor until surgical exploration, the pathology is clear.

Differential diagnosis of spermatic cord malignant tumor

Inguinal hernia

The scrotum and bulge in the scrotum or groin, but it is reversible, appears when standing, disappears when lying down, the groin subcutaneous ring increases the impact of coughing, percussion is a drum sound, auscultation can smell bowel sounds.

2. testicular hydrocele

The mass in the scrotum was pear-shaped, fluctuating, and the light transmission test was positive. Testicular spermatic cord palpation was normal after diagnostic puncture.

3. Testicular tumor

A substantial mass in the scrotum. The palpability of the testes is obvious when palpated, hard and inelastic, while palpation of the testis on the side of the spermatic cord is normal.

4. spermatic cord effusion

The volume of the mass that traveled along the spermatic cord was small, and it was positive for the cystic light transmission test. A round or oval sound-transmitting area appeared in the spermatic cord with B-mode ultrasound.

5.Semen cyst

It is a mass in the scrotum. It is similar to a small tumor in the spermatic cord but a cystic mass in the epididymis head. It has a clear boundary, a small volume and a round shape. The ultrasound image has a circular sound-permeable area on the epididymal head. Usually 1 ~ 2cm. Diagnostic puncture can extract milky white sperm-containing fluid.

Spermatic cord malignant tumor treatment

Surgery

For malignant tumors, the seminiferous cord and vas deferens should be severed at the inner groin ring, and the ipsilateral testes should be excised. Involving the scrotum should be resected as a whole.

2. Radiotherapy and chemotherapy

Radiotherapy is suitable for patients whose primary lesions cannot be removed. The irradiation range should include the retroperitoneum, ipsilateral pelvic cavity and groin. The dose is 40-60Gy. Vincristine D, cyclophosphamide combined chemotherapy may have some effect.

3. Not suitable for lymphatic dissection

Leiomyosarcoma of the seminiferous cord is mainly metastatic by blood, and retroperitoneal lymph node dissection is generally not appropriate.
