What is the recommended clinical staging work‑up before orchiectomy for testicular cancer?

Clinical Staging Prior to Orchiectomy for Testicular Cancer

Before performing orchiectomy, the essential staging work-up consists of high-frequency testicular ultrasound (>10 MHz), serum tumor markers (AFP, hCG, and LDH), clinical examination of both testes, abdomen, supraclavicular fossae, and chest for gynaecomastia. 1

Pre-Orchiectomy Clinical Assessment

Physical Examination

• Examine both testes to assess for bilateral disease or contralateral abnormalities 1
• Palpate the abdomen and supraclavicular fossae to detect bulky lymphadenopathy 1
• Inspect the chest for gynaecomastia, which may indicate hCG-secreting tumors 1

Imaging Studies

Testicular Ultrasound (Mandatory)

• Use high-frequency ultrasound (>10 MHz) to confirm the presence of a testicular mass 1
• Ultrasound determines whether the mass is intratesticular versus extratesticular, assesses lesion size, detects multifocal disease, and evaluates the contralateral testicle 1
• This is the initial and essential imaging modality for any scrotal mass before orchiectomy 1

Cross-Sectional Imaging (Not Routinely Required Pre-Orchiectomy)

• CT abdomen/pelvis and chest imaging are post-orchiectomy staging procedures, not pre-operative requirements 1
• The exception: if the patient presents with life-threatening metastatic disease (acute abdominal crisis, respiratory compromise, extensive retroperitoneal masses), imaging may precede orchiectomy to guide urgent chemotherapy 2

Serum Tumor Markers (Essential)

Pre-Orchiectomy Marker Levels

• Measure AFP, hCG, and LDH before surgery 1
• These markers support the diagnosis of germ cell tumor and may indicate histology 1
• Normal marker levels do not exclude testicular cancer due to low sensitivity 1

Post-Orchiectomy Marker Kinetics

• Repeat markers after orchiectomy, accounting for half-life kinetics: AFP half-life ≈ 5-7 days, hCG half-life ≈ 24-36 hours 3
• Delayed decline or rising levels indicate residual disease and upstage the patient even with negative imaging 1, 3

Common Clinical Pitfalls

When to Delay Orchiectomy

• In patients with advanced disease causing acute symptoms (massive retroperitoneal masses with ureteral obstruction, extensive pulmonary metastases), primary chemotherapy before orchiectomy may be life-saving 2
• Modern imaging (testicular ultrasound, CT, tumor markers) provides sufficient diagnostic evidence to initiate treatment without tissue diagnosis in these emergent scenarios 2
• Delayed orchiectomy is performed after chemotherapy, either alone or simultaneously with retroperitoneal lymph node dissection 2

Contralateral Testis Evaluation

• Routine contralateral biopsy remains controversial 1
• Biopsy is indicated for patients at high risk of contralateral germ cell neoplasia in situ (GCNIS): testicular volume <12 mL or history of cryptorchidism 1
• Do not biopsy patients >40 years without risk factors 1

Fertility Preservation

• Offer semen cryopreservation before orchiectomy whenever feasible 1
• Sperm abnormalities and Leydig cell dysfunction are frequently present even before surgery 1
• This maximizes future fertility options, as treatment (including orchiectomy alone) may impair reproductive function 1

Algorithmic Approach to Pre-Orchiectomy Staging

1. Clinical suspicion of testicular cancer → Perform testicular ultrasound (>10 MHz) 1
2. Intratesticular mass confirmed → Obtain serum AFP, hCG, LDH 1
3. Complete physical examination → Assess both testes, abdomen, supraclavicular nodes, chest 1
4. Discuss fertility preservation → Offer sperm banking before surgery 1
5. Proceed to inguinal orchiectomy (avoid scrotal approach due to higher local recurrence) 1
6. Post-orchiectomy: Repeat tumor markers, obtain histopathology, then perform cross-sectional imaging (CT abdomen/pelvis with contrast, chest radiograph or CT) for definitive staging 1

Exception: If the patient presents with life-threatening metastatic disease, obtain CT imaging and consider neoadjuvant chemotherapy before orchiectomy 2

Post-Orchiectomy Staging (For Context)

After orchiectomy, definitive staging requires:

• Histopathological pT classification from the orchiectomy specimen 1, 3
• Post-orchiectomy serum tumor markers with attention to half-life kinetics 1, 3
• CT abdomen and pelvis with IV contrast (reference standard for retroperitoneal lymphadenopathy; sensitivity 73-97%, nodes >1 cm highly suspicious) 1, 3
• Chest radiograph for seminoma; chest CT for non-seminoma or if chest X-ray/abdominal CT is abnormal 1
• MRI abdomen/pelvis is an equivalent alternative to CT, particularly with diffusion-weighted imaging 1
• Brain MRI only if symptomatic or high-risk features (hCG >5000 IU/L, extensive lung metastases) 1

The TNM classification and IGCCCG prognostic system are applied after orchiectomy to guide adjuvant therapy or surveillance 1, 3
