Multidisciplinary Evaluation (First Step)[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=4 "Edit section: 1.

Multidisciplinary Evaluation (First Step)")] Before finalizing treatment, the case is reviewed by a team including surgical oncology, medical oncology, radiation oncology, gastroenterology, and radiology. Key goals: * Confirm the tumor is truly resectable (no vascular invasion that would prevent surgery). * Assess overall fitness for major surgery (Whipple procedure). * Consider CA19-9 level, performance status, and any signs of occult metastatic disease. ### 2. Neoadjuvant Therapy (Increasingly Standard)[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=5 "Edit section: 2.

Neoadjuvant Therapy (Increasingly Standard)")] In 2024–2025 practice, most major cancer centers now recommend neoadjuvant therapy, even for clearly resectable tumors. ##### Why neoadjuvant therapy?[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=6 "Edit section: Why neoadjuvant therapy?") | [edit source](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&action=edit§ion=6 "Edit section's source code: Why neoadjuvant therapy?")] * Treat micrometastatic disease early * Improve the chance of an R0 (clean margin) resection * Select out patients with biologically aggressive disease * Higher completion rates of systemic therapy compared with postoperative start ##### Typical regimens:[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=7 "Edit section: Typical regimens:") | [edit source](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&action=edit§ion=7 "Edit section's source code: Typical regimens:")] * Modified FOLFIRINOX (the most active regimen for fit patients) * Gemcitabine + nab-paclitaxel (for patients not candidates for FOLFIRINOX) Duration is usually 2–4 months, followed by imaging to confirm ongoing operability. Neoadjuvant chemoradiation may be considered in some programs, especially if close margins are expected. ### 3. Surgical Resection (Whipple Procedure)[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=8 "Edit section: 3.

Surgical Resection (Whipple Procedure)")] If the tumor remains resectable after neoadjuvant therapy, the standard operation is: ##### Pancreaticoduodenectomy (Whipple procedure)[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=9 "Edit section: Pancreaticoduodenectomy (Whipple procedure)") | [edit source](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&action=edit§ion=9 "Edit section's source code: Pancreaticoduodenectomy (Whipple procedure)")] Often done at high-volume centers due to the complexity and outcome differences. Goals: * Remove tumor with negative margins (R0) * Evaluate lymph nodes (at least 12 sampled) ### 4. Adjuvant Therapy (After Surgery)[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=10 "Edit section: 4.

Adjuvant Therapy (After Surgery)")] Regardless of neoadjuvant therapy, additional postoperative treatment is standard unless the patient cannot tolerate it. ##### Preferred adjuvant regimens:[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=11 "Edit section: Preferred adjuvant regimens:") | [edit source](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&action=edit§ion=11 "Edit section's source code: Preferred adjuvant regimens:")] * mFOLFIRINOX (best survival benefit if patient can tolerate) * Gemcitabine + capecitabine (more tolerable alternative) Typical duration: 6 months total therapy, including both neoadjuvant and adjuvant phases. ### 5. Surveillance[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=12 "Edit section: 5.

Surveillance")] After completing therapy: CT scans every 3–6 months for the first 2 years, then every 6–12 months, plus CA19-9 monitoring when appropriate. ### Summary (Single-Sentence Standard of Care)[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=13 "Edit section: Summary (Single-Sentence Standard of Care)") | [edit source](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&action=edit§ion=13 "Edit section's source code: Summary (Single-Sentence Standard of Care)")] For a localized, operable pancreatic head adenocarcinoma, the modern standard of care is neoadjuvant systemic therapy (typically mFOLFIRINOX), followed by Whipple surgery if still resectable, and completion of adjuvant chemotherapy, with surveillance thereafter. If you’d like, I can tailor this to your specific tumor size (18 mm), age, fitness level, and treatment goals. ## References[[edit](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&veaction=edit§ion=14 "Edit section: References") | [edit source](https://freemwiki.com/index.php?title=Openai/69379cd5-50a8-8010-a3a0-3e79e4f09d90&action=edit§ion=14 "Edit section's source code: References")] 1.
