Radical lymph node dissection and assessment: Impact on gallbladder cancer prognosis

Figure 1 Kaplan-Meier survival estimates stratified. A: Lymph node status (negative vs positive; median disease-specific survival, 40 mo vs 17 mo); B: pN status in nodal positive patients (pN₁vs pN₂; median disease-specific survival, 18 mo vs 13 mo).

Figure 2 Kaplan-Meier survival estimates stratified for total lymph node count status (< 4 or ≥ 4, respectively). A: In 78 patients who underwent an R0 resection (median disease-specific survival, 18 mo vs 33 mo); B: In 41 node-negative patients (median disease-specific survival, 37 mo vs 54 mo). TLNC: Total lymph node count.

Figure 3 Kaplan-Meier survival estimates stratified for total lymph node count status in 37 node-positive patients. A: n < 4 or ≥ 4, respectively; median disease-specific survival, 13 mo vs 21 mo; B: n < 6 or ≥ 6, respectively; median disease-specific survival, 15 mo vs 33 mo. TLNC: Total lymph node count.
