Bulky Mediastinal Hodgkin Lymphoma in a 16-Year-Old: Anesthetic and Fertility Decisions
16-year-old boy presents with a three-week history of neck swelling, night sweats, and a nonproductive cough. CT shows an 11 cm anterior mediastinal mass with mild tracheal narrowing and a small pericardial effusion. He has orthopnea and stridor when lying flat but is comfortable sitting upright. PET-CT shows uptake in the mediastinum and bilateral supraclavicular nodes without distant disease. Core biopsy confirms classic Hodgkin lymphoma. The team plans ABVD and involved-site radiotherapy. Before starting, he needs staging bone marrow and pulmonary function tests, and the anesthesiology team is reluctant to provide general anesthesia for a bone marrow biopsy because of the mediastinal mass. His parents ask about fertility and whether chemotherapy can be delayed for sperm banking.
1. How would you evaluate and manage the anesthetic risk for staging procedures, and can you avoid general anesthesia?

A large anterior mediastinal mass with orthopnea and stridor is a high-risk airway and cardiovascular situation. General anesthesia can cause loss of spontaneous respiration, positive-pressure ventilation, and positional airway collapse, leading to catastrophic obstruction or cardiovascular collapse. I would avoid general anesthesia if possible.
Alternatives:
- Perform a bone marrow biopsy under local anesthesia with conscious sedation in the upright or semi-upright position, with anesthesia standby and a plan for rescue.
- If general anesthesia is unavoidable, obtain cardiothoracic surgery and ECMO backup, maintain spontaneous ventilation if feasible, avoid muscle relaxation until the airway is secured, and position the patient upright or in the position of comfort.
- Assess the pericardial effusion and superior vena cava syndrome clinically; obtain echocardiography if there is concern about tamponade.
- Proceed with staging PET-CT and blood tests that do not require anesthesia. Bone marrow biopsy is often omitted in early-stage Hodgkin lymphoma when PET-CT is negative, but it may still be requested in this protocol; I would question whether it changes management.
The key is a multidisciplinary plan, not simply cancelling the procedure or proceeding with routine general anesthesia.
2. What fertility counseling would you provide, and would you delay chemotherapy for sperm banking?
Read the worked answer
Fertility counseling is mandatory before starting chemotherapy. ABVD is generally considered lower risk for gonadal toxicity than alkylator-heavy regimens, but it is not zero risk, and he may need salvage therapy later. Sperm banking is the standard option for a postpubertal male and should be offered before the first chemotherapy dose.
A short delay of 1–2 days for sperm banking is usually acceptable in Hodgkin lymphoma, especially when there is no impending airway compromise. I would explain that the mediastinal mass makes timing important but that a brief delay for fertility preservation is reasonable. If he cannot producessperm, testicular sperm extraction or experimental options can be discussed, but these are less standard.
I would also document the discussion with the parents and the patient, because assent and confidentiality matter in an adolescent. After treatment, refer for semen analysis if fertility is a concern. Do not use a GnRH agonist as a substitute for sperm banking; evidence for gonadal protection in males is weak.
3. How would you monitor and mitigate bleomycin pulmonary toxicity during ABVD, and what would you do about G-CSF use?
Read the worked answer
Bleomycin pulmonary toxicity is dose-related and can be potentiated by high inspired oxygen, fluid overload, renal impairment, and chest radiation. Before treatment, obtain baseline pulmonary function tests and document oxygen saturation. During treatment, monitor for cough, dyspnea, and falling DLCO; avoid unnecessary high FiO2 and aggressive fluid resuscitation. If pulmonary toxicity develops, stop bleomycin and evaluate with high-resolution CT and pulmonary consultation.
G-CSF use with ABVD is controversial because some data suggest an increased risk of bleomycin pulmonary toxicity when G-CSF is given concurrently. I would avoid routine primary G-CSF prophylaxis with ABVD unless the patient has a compelling reason, such as febrile neutropenia in a prior cycle or prolonged neutropenia. If G-CSF is needed, I would discuss the trade-off and monitor respiratory symptoms closely.
Because he has bulky mediastinal disease, he will likely receive involved-site radiotherapy after chemotherapy. I would minimize radiation dose and volume to the lungs, coordinate the bleomycin exposure, and obtain pulmonary function before and after treatment. If his pulmonary function is marginal, I would consider omitting bleomycin and using an alternative regimen after multidisciplinary discussion.
