Common questions3 answered from the recorded discussions
Who requires surgical intervention for circumcision?

Patients requiring surgical intervention for circumcision include infants over 3 months of age or weighing more than 13 pounds, who cannot safely undergo office circumcision. Additionally, patients with isolated chordee without hypospadias benefit from operative circumcision to release adhesions and straighten the penis. Conversely, elective circumcision in infants under 3 months should not require general anesthesia due to anesthetic safety concerns.

How is Sarcoma (Ewing/Rhabdo) diagnosed?

Diagnosis of soft tissue sarcomas (rhabdo and non-rhabdo) involves imaging and tissue sampling. The workup includes MRI and either incisional or core biopsy. Histological grade is critical in non-rhabdomyosarcoma soft tissue sarcomas for treatment decisions. For regional disease assessment, sentinel node biopsy is performed because clinically negative nodes may harbor occult disease; 40–50% of biopsied nodes are positive, and positive nodes carry worse prognosis and require radiation therapy.

What did Todd Ponsky say about Sarcoma (Ewing/Rhabdo)?

Todd Ponsky discussed surgical decision-making for non-rhabdomyosarcoma soft tissue sarcomas. He presented a study comparing outcomes between patients who had unplanned excision of lesions later found to be non-rhabdomyosarcoma followed by re-excision versus those with planned workup and excision. The study involved 40 patients referred after innocuous lesion removal that returned as non-rhabdomyosarcoma. Ponsky concluded that since there is no outcome difference between planned and unplanned excision, it may be acceptable with low index of suspicion to excise the lesion and perform re-excision if it returns as non-rhabdomyosarcoma.

Takeaways+ Show
Sarcoma (Ewing/Rhabdo) encompasses two distinct pediatric malignancies with divergent biology and management. Rhabdomyosarcoma represents half of pediatric soft tissue sarcomas, with abdominal/pelvic/retroperitoneal primaries carrying the worst prognosis and orbital sites the best [e672-c18,c19,c20]. Sentinel lymph node biopsy is now mandatory for trunk/extremity disease, with 40–50% positivity rates; completion dissection is omitted in favor of radiation [e672-c23,c24,c25]. Unplanned excision—common when innocuous lesions return as sarcoma—yields 45.7% residual tumor at re-excision yet shows no survival difference versus planned wide excision, supporting re-excision over primary morbidity [e326-c7,c8,c9,c10]. Ewing sarcoma arises from EWSR1-ETS fusions (detectable in ≥95%), predominantly skeletal (75–80%), and is rare in East Asian/Sub-Saharan populations [e10175-c1,c2,c3]. Stage dominates prognosis: localized disease achieves 80% survival versus 20% for metastatic . Circulating tumor DNA at diagnosis predicts ~50% event-free survival in localized disease [e10175-c8,c9]. Surgical resection with negative margins is preferred for local control when feasible; definitive radiotherapy doubles local failure risk but remains appropriate for high-morbidity sites (deep pelvis, paraspine) [e10175-c13,c14,c16,c17]. Metastasectomy for pulmonary relapse—especially solitary nodules—achieves 73% three-year survival versus 40% for multiple nodules, supporting aggressive local control in oligometastatic recurrence [e11335-c7,c8,c12].
  1. Sentinel node biopsy is required for trunk/extremity rhabdo; 40–50% are positive, managed with radiation not completion dissection.
  2. Unplanned sarcoma excision yields 45.7% residual tumor but no survival difference versus planned resection; re-excise rather than accept primary morbidity.
  3. Ewing stage is paramount: localized 80% survival, metastatic 20%. Circulating tumor DNA at diagnosis predicts ~50% event-free survival in localized disease.
  4. Surgical resection preferred for Ewing local control when feasible; definitive RT doubles local failure risk but appropriate for high-morbidity sites.
  5. Solitary pulmonary Ewing relapse: 73% three-year survival with metastasectomy ± whole-lung RT versus 40% for multiple nodules—aggressive local control warranted.
For patients & families
When doctors find a lump or mass in a child, they need to figure out what it is. Sometimes these turn out to be sarcomas—cancers that grow in soft tissues (like muscle) or bones. Two types that affect children are Ewing sarcoma and rhabdomyosarcoma . Ewing sarcoma usually starts in bones but can also appear in soft tissue, and it's quite rare in children of East Asian or African ancestry . Rhabdomyosarcoma is the most common soft tissue cancer in children, and where it grows matters a lot—tumors in the belly, pelvis, or behind the belly have worse outcomes than those near the eye . If your child needs a biopsy, doctors can often use a needle guided by imaging rather than surgery, which works well and is safer . Treatment usually includes chemotherapy, and sometimes surgery or radiation to remove or shrink the tumor . The doctors will check whether cancer has spread to lymph nodes or lungs, because that affects the treatment plan and what to expect .

Pediatric and Young Adult Image-Guided Percutaneous Bone Biopsy-A New Standard of Care?
The study evaluated 169 biopsies in 141 patients over a 10-year period at a single institution.
clinicalSophia Schermerhorn0:13 ↗
Nearly 90% of the biopsies were core-needle biopsies.
clinicalSophia Schermerhorn0:19 ↗
All biopsies were performed with image guidance, most commonly CT, sometimes combined with fluoroscopy and ultrasound.
clinicalSophia Schermerhorn0:22 ↗
All biopsies were performed by interventional radiologists.
clinicalSophia Schermerhorn0:28 ↗
97.9% of biopsies were diagnostic.
clinicalSophia Schermerhorn0:33 ↗
Only 3 patients required repeat biopsy.
clinicalSophia Schermerhorn0:33 ↗
There was one patient with transient sciatic nerve paresis, which resolved.
clinicalSophia Schermerhorn0:40 ↗
The complication rate was 0.7%.
clinicalSophia Schermerhorn0:43 ↗
The approach provided sufficient tissue for histology, immunostains, and molecular studies.
clinicalSophia Schermerhorn0:46 ↗
Immunostains and molecular studies are increasingly essential for modern risk stratification and targeted therapy.
clinicalSophia Schermerhorn0:46 ↗
Image-guided percutaneous biopsy should be strongly considered the diagnostic modality of choice for pediatric bone and soft tissue tumors.

Early Postoperative Fever in Pediatric Oncology Patients Undergoing Solid Tumor Resection
42% of 220 oncology patients had a fever in the 48 hours following tumor resection
epidemiologicalSophia Schermerhorn0:12 ↗
Only 2 of the febrile patients (2.8%) had an actual infection
epidemiologicalSophia Schermerhorn0:19 ↗
The two patients with actual infection were hemodynamically unstable with positive blood cultures
clinicalSophia Schermerhorn0:19 ↗
Most fevers triggered a workup that costs on average about $500 per patient
epidemiologicalSophia Schermerhorn0:30 ↗
About a third of patients received empiric antibiotics that they did not need
epidemiologicalSophia Schermerhorn0:30 ↗
In the 48 hours following tumor resection, fever alone may not be a reason to panic
opinionSophia Schermerhorn0:40 ↗
Extensive workup should be reserved for patients who are hemodynamically unstable or have more overt signs of infection
