GE Cancer 2 Flashcards
What is the most common location of esophageal squamous cell carcinoma?
Cervical esophagus.
For esophageal or GEJ cancer, when is a bronchoscopy needed for staging?
If tumor is at or above carina - to rule out posterior trachea invasion
When to do staging laparoscopy?
Gastric tumors that are cT1b or higher
T stage in GEJ or distal esophageal cancer?
T1a: mucosa
T1b: submucosa
T2: muscularis propria
T3: Adventitia
T4a: Adjacent structures, debatably resectable
T4b: Adjacent structures, unresectable
What is the treatment for T1aN0 distal esophageal or GEJ adenocarcinoma?
Endomucosal resection
What is the treatment for T1bN0 distal esophageal or GEJ adenocarcinoma?
Surgery
What is the treatment paradigm for locally advanced, resectable distal esophageal or GEJ adenocarcinoma?
ChemoRT and surgery
What classifies a distal esophageal or GEJ adenocarcinoma as locally advanced, resectable? (2)
T2-T4a N0
Tany N+ (mediastinal or celiac)
What classifies a distal esophageal or GEJ adenocarcinoma as locally advanced unresectable?
T4b Nany
What is the treatment paradigm for locally advanced unresectable distal esophageal or GEJ adenocarcinoma
ChemoRT
Preferred Neoadjuvant chemoradiation regimen for distal esophageal or GEJ cancer?
Carboplatin + Paclitaxel (CROSS regimen)
Patient with distal esophageal or GEJ cancer undergoes neoadjuvant chemoradiation and surgery. He has residual tumor at the time of surgery. What now?
Adjuvant nivolumab x1 year
Preferred treatment for locally advanced resectable esophageal squamous cell carcinoma?
Neoadjuvant Carbo+Taxol+RT then surgery
Preferred perioperative chemotherapy for GEJ adenoca, distal esophageal adenoca, or gastric adenoca
FLOT (5-FU+LV+Oxaliplatin+Docetaxel) for fit patients
What patient population do not benefit from perioperative chemotherapy without radiation?
esophageal SCC
Preferred treatment for locally advanced resectable gastric adenocarcinoma?
Perioperative FLOT and then surgery
patient with gastric adenocarcinoma has up front surgical resection and has a T2N0 tumor. He had a D1 dissection. What adjuvant treatment?
ChemoRT (5-FU+RT)
Patient with gastric cancer had up front surgery and had T3N0 disease. He had a D2 dissection. Adjuvant treatment?
Chemotherapy alone (CAPOX)
What is a D1 surgery in gastric cancer?
Removal of N1 nodes
You have a patient with esophageal SCC undergoing neoadjuvant chemoRT, but he didn’t tolerate therapy well and is a borderline surgical candidate. What can you do to feel better about avoiding surgery?
EGD/biopsy.
Negative EGD/biopsy and PET/CT means we can omit surgery
What is a D2 surgery in gastric cancer?
Removal of N1 and N2 nodes
What is the preferred treatment for locally advanced unresectable adenocarcinoma or squamous cell carcinoms of Distal esophagus or GEJ?
Cisplatin + 5-FU + RT
FOLFOX + RT
How does the local management of cervical esophageal cancer differ from other esophageal cancers?
Usually considered inoperable, even if not T4b.
-Hard to do anastomosis, usually SCC, generally treated with definitive chemoRT
