ICG-guided #sentinel lymph node mapping remains highly successful across #BMI groups in #uterine cancer

✅ High success across BMI groups
⚠️ ↓ with BMI ≥60 + laparotomy
📈 Better with experience
📦 Empty nodal packet rates low

Bittersweet time of the year. Just finished exent with 2 of my amazing senior fellows there in their last week of fellowship!! 2 other amazing graduates also finishing. Will miss you!

[MSKCC Team Uterus @TeamEndo_MSK]

Our international fellow @GuidoReyv led an engaging discussion this morning on trends and controversies in the surgical management of cervical cancer.

[IJGC @IJGConline]

More imaging ≠ better outcomes 🚫
In early cervical cancer (FIGO ≤IB2, ≤4 cm on MRI):
❌ Additional CT/PET found no extra-pelvic disease
⚠️ 100% false positives → unnecessary biopsies & interventions
😟 Added “scanxiety” + cost burden
➡️ No impact on management

🛑 Routine imaging beyond MRI may do more harm than good

🤔 Can you imagine a #GynOnc field without Mario Leitao?

Dr. Leitao @leitaomd shares how he nearly quit his OB/GYN residency... until that pivotal moment changed everything! 🍻➡️⚕️

Honored to have led our introductions, icebreaker and the Fellow's Panel with @SGO_org LEAD! The future is bright! Excited to co-chair with Kristy Ward next year! @ChrisDagherMD #representationmatters

In FIGO stage I endometrioid endometrial carcinoma, discordant-grade tumors that are initially high grade on biopsy and lower grade on hysterectomy behave more aggressively compared with concordant low-grade tumors. @tsialater @leitaomd

De-escalation in Stage IC epithelial ovarian cancer—can we safely do less? 🤔
🔬 Histology-driven decisions
🟢 Safe omission possible in select subtypes
⚖️ Balance survival benefit vs toxicity
🤝 Shared decision-making is essential

Not all Stage IC needs chemo — precision matters.

So thankful for the opportunity to present at my favorite conference @ESGO_society in Denmark. Had the best time and had to rep my @ENYGO_official famiglia today in the OR as I process missing them until next time!

[Mario M. Leitao, Jr @leitaomd]

Time to re-assess value and cost of "routine" imaging in low grade endometrial cancer. CT and MRI are of low value in most low grade endometrial cancers.

Positive peritoneal cytology = not so “low risk.”
In stage IA G1 endometrioid EC, it doubled progression risk (aHR 2.6) and tracked with ARID1A loss.
