The optimal number of examined lymph nodes for accurate staging of intrahepatic cholangiocarcinoma: A multi-institutional analysis using the nodal staging score model. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:1429-1435. [PMID: 37005204 DOI: 10.1016/j.ejso.2023.03.221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 03/19/2023] [Accepted: 03/21/2023] [Indexed: 04/03/2023]
Abstract
BACKGROUND This study aims to develop a nodal staging score (NSS) to determine the optimal number of lymph nodes (LNs) examined in intrahepatic cholangiocarcinoma (iCCA) patients. METHODS Clinicopathologic data were collected from the SEER database (development cohort, n = 2782) and seven Chinese tertiary hospitals (validation cohort, n = 363). NSS was constructed based on a binomial distribution to indicate the probability of nodal disease absence. In addition, its prognostic value was examined by survival analysis and multivariable modeling on pN0 patients. RESULTS A model fit was performed in node-positive patients and a subgroup analysis was performed according to clinical characteristics. Statistically significant differences were only found in the subgroups when divided by the tumor size of 3 cm. As the number of examined lymph nodes (ELNs) increased, the likelihood of missing a metastatic LN decreased. NSS escalated as ELNs increased in groups with different tumor sizes, with plateaus at 7 and 11 LNs ensuring an NSS of 90.0% for ≤3 cm and >3 cm tumors, respectively. For pN0 patients, multivariate analysis revealed that NSS was an independent prognostic factor for overall survival (OS) and recurrence-free survival (RFS). CONCLUSIONS For accurate staging of iCCA, the optimal number of ELNs was related to tumor size. We recommend that at least 7 and 11 LNs should be examined for tumor size ≤3 cm and >3 cm, respectively. Therefore, the NSS model could be helpful to make clinical decisions for pN0 iCCA.

Reappraisal of T1b gallbladder cancer (GBC): clinicopathologic analysis of 473 in situ and invasive GBCs and critical review of the literature highlights its rarity, and that it has a very good prognosis. Virchows Arch 2023; 482:311-323. [PMID: 36580138 DOI: 10.1007/s00428-022-03482-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 12/05/2022] [Accepted: 12/17/2022] [Indexed: 12/30/2022]
Abstract
There are highly conflicting data on relative frequency (2-32%), prognosis, and management of pT1b-gallbladder carcinoma (GBC), with 5-year survival ranging from > 90% in East/Chile where cholecystectomy is regarded as curative, versus < 50% in the West, with radical operations post-cholecystectomy being recommended by guidelines. A total of 473 in situ and invasive extensively sampled GBCs from the USA (n = 225) and Chile (n = 248) were re-evaluated histopathologically per Western invasiveness criteria. 349 had invasive carcinoma, and only 24 were pT1. Seven cases previously staged as pT1b were re-classified as pT2. There were 19 cases (5% of all invasive GBCs) qualified as pT1b and most pT1b carcinomas were minute (< 1mm). One patient with extensive pTis at margins (but pT1b focus away from the margins) died of GBC at 27 months, two died of other causes, and the remainder were alive without disease (median follow-up 69.9 months; 5-year disease-specific survival, 92%). In conclusion, careful pathologic analysis of well-sampled cases reveals that only 5% of invasive GBCs are pT1b, with a 5-year disease-specific survival of > 90%, similar to findings in the East. This supports the inclusion of pT1b in the "early GBC" category, as is typically done in high-incidence regions. Pathologic mis-staging of pT2 as pT1 is not uncommon. Cases should not be classified as pT1b unless extensive, preferably total, sampling of the gallbladder to rule out a subtle pT2 is performed. Critical appraisal of the literature reveals that the Western guidelines are based on either SEER or mis-interpretation of stage IB cases as "pT1b." Although the prognosis of pT1b-GBC is very good, additional surgery (radical cholecystectomy) may be indicated, and long-term surveillance of the biliary tract is warranted.

Values of spleen-preserving distal pancreatectomy in well-differentiated non-functioning pancreatic neuroendocrine tumors: a comparative study. Gastroenterol Rep (Oxf) 2022; 10:goac056. [PMID: 36263393 PMCID: PMC9562143 DOI: 10.1093/gastro/goac056] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 09/18/2022] [Accepted: 09/25/2022] [Indexed: 11/14/2022] Open
Abstract
Background The feasibility of spleen-preserving distal pancreatectomy (SPDP) to treat well-differentiated non-functioning pancreatic neuroendocrine tumors (NF-pNETs) located at the body and/or tail of the pancreas remains controversial. Distal pancreatectomy with splenectomy (DPS) has been widely applied in the treatment of NF-pNETs; however, it may increase the post-operative morbidities. This study aimed to evaluate whether SPDP is inferior to DPS in post-operative outcomes and survivals when being used to treat patients with NF-pNETs in our institute. Methods Clinicopathological features of patients with NF-pNETs who underwent curative SPDP or DPS at the First Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) between January 2010 and January 2022 were collected. Short-term outcomes and 5-year survivals were compared between patients undergoing SPDP and those undergoing DPS. Results Sixty-three patients (SPDP, 27; DPS, 36) with well-differentiated NF-pNETs were enrolled. All patients had grade 1/2 tumors. After identifying patients with T1-T2 NF-pNETs (SPDP, 27; DPS, 15), there was no disparity between the SPDP and DPS groups except for tumor size (median, 1.4 vs 2.6 cm, P = 0.001). There were no differences in operation time (median, 250 vs 295 min, P = 0.478), intraoperative blood loss (median, 50 vs 100 mL, P = 0.145), post-operative major complications (3.7% vs 13.3%, P = 0.287), clinically relevant post-operative pancreatic fistula (22.2% vs 6.7%, P = 0.390), or post-operative hospital stays (median, 9 vs 9 days, P = 0.750) between the SPDP and DPS groups. Kaplan-Meier curve showed no significant differences in the 5-year overall survival rate (100% vs 100%, log-rank P > 0.999) or recurrence-free survival (100% vs 100%, log-rank P > 0.999) between patients with T1-T2 NF-pNETs undergoing SPDP and those undergoing DPS. Conclusions In patients with T1-T2 well-differentiated NF-pNETs, SPDP could achieve comparable post-operative outcomes and prognosis compared with DPS.

Abstract
OPINION STATEMENT Biliary malignancies, although rare, can be some of the most challenging to manage surgically. Intrahepatic cholangiocarcinomas are resectable if there is no evidence of metastatic disease. These tumors are managed with anatomic resection and portal lymphadenectomy when centrally located or multiple in a single lobe. Non-anatomic resection can be performed for solitary peripheral tumors with minimally invasive techniques. It is not our practice to routinely employ neoadjuvant chemotherapy prior to resection of these tumors. Hepatic arterial infusion chemotherapy is utilized at our institution in highly selected patients in the context of an ongoing clinical trial for unresectable tumors. Hilar cholangiocarcinomas, when resectable (i.e., ipsilateral arterial involvement or lack of vascular involvement), are managed with right or left (extended) hepatectomy, caudate resection, and portal lymphadenectomy. Distal cholangiocarcinomas are managed with pancreaticoduodenectomy. Neoadjuvant chemotherapy is not routinely used in our treatment algorithm of extrahepatic cholangiocarcinomas. Nodal involvement and positive margin (R1) resection necessitates adjuvant chemotherapy. Finally, gallbladder carcinoma is managed with radical cholecystectomy, anatomic segment IVb/V resection, and portal lymphadenectomy. Adjuvant chemotherapy is employed routinely amongst patients with T2 or higher tumors and those with positive lymph nodes.

Impact of lymph nodal stage on gallbladder cancer survival after extended cholecystectomy and adjuvant radiochemotherapy: long-term results from an oncology institute, Chile. Ecancermedicalscience 2021; 15:1222.

Abstract
Introduction Gallbladder cancer (GBC) is one of the most important causes of cancer death in Chile. Materials and methods A retrospective review of 103 patients with a diagnosis of GBC who were treated with surgery and adjuvant radiochemotherapy (RT-CT) was carried out at the Oncological Institute of Viña del Mar, Chile. Of these, 56 underwent surgery with oncological criteria, in which the impact of lymph node involvement and prognostic factors for survival were analysed. Results The median follow-up was 47.5 months. The 5-year survival of the patients operated on with oncological surgery was 55%, and for those resected without oncological criteria, it was 32% (p = 0.02). Regarding the impact of lymph node involvement, 5-year overall survival (OS) in patients with compromised lymph nodes was 32% versus 68% for patients without compromised lymph nodes (p = 0.006). Five-year OS in patients without involved nodes, with 1 involved node or with>1 involved node was 68%, 44% and 12%, respectively (p = 0.0002). The N ratio was grouped in 0, <10% and ≥10%. Five-year OS was 71%, 0% and 24%, respectively (p = 0.003). There was no evidence of differences in survival with respect to the number of lymph nodes studied. Conclusion Our data provide information regarding the importance of lymph node involvement in patients with GBC undergoing surgery with oncological criteria and adjuvant RT-CT. In the absence of randomised studies, it is suggested to have a more aggressive therapeutic approach in those patients with two or more involved nodes or with a lymph node ratio >10%.

Validation of the 8th Edition American Joint Commission on Cancer (AJCC) Gallbladder Cancer Staging System: Prognostic Discrimination and Identification of Key Predictive Factors. Cancers (Basel) 2021; 13:cancers13030547. [PMID: 33535552 PMCID: PMC7867111 DOI: 10.3390/cancers13030547] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 01/19/2021] [Accepted: 01/26/2021] [Indexed: 12/21/2022] Open
Abstract
The scope of our study was to compare the predictive ability of American Joint Committee on Cancer (AJCC) 7th and 8th edition in gallbladder carcinoma (GBC) patients, investigate the effect of AJCC 8th nodal status on the survival, and identify risk factors associated with the survival after N reclassification using the National Cancer Database (NCDB) in the period 2005-2015. The cohort consisted of 7743 patients diagnosed with GBC; 202 patients met the criteria for reclassification and were denoted as stage ≥III by AJCC 7th and 8th edition criteria. Overall survival concordance indices were similar for patients when classified by AJCC 8th (OS c-index: 0.665) versus AJCC 7th edition (OS c-index: 0.663). Relative mortality was higher within strata of T1, T2, and T3 patients with N2 compared with N1 stage (T1 HR: 2.258, p < 0.001; T2 HR: 1.607, p < 0.001; Τ3 HR: 1.306, p < 0.001). The risk of death was higher in T1-T3 patients with Nx compared with N1 stage (T1 HR: 1.281, p = 0.043, T2 HR: 2.221, p < 0.001, T3 HR: 2.194, p < 0.001). In patients with AJCC 8th edition stage ≥IIIB GBC and an available grade, univariate analysis showed that higher stage, Charlson-Deyo score ≥ 2, higher tumor grade, and unknown nodal status were associated with an increased risk of death, while year of diagnosis after 2013, academic center, chemotherapy. and radiation therapy were associated with decreased risk of death. Chemotherapy and radiation therapy were associated with decreased risk of death in patients with T3-T4 and T2-T4 GBC, respectively. In conclusion, the updated AJCC 8th GBC staging system was comparable to the 7th edition, with the recently implemented changes in N classification assessment failing to improve the prognostic performance of the staging system. Further prospective studies are needed to validate the T2 stage subclassification as well as to clarify the association, if any is actually present, between advanced N staging and increased risk of death in patients of the same T stage.
