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.

Comparison of clinicopathological characteristics of mucinous adenocarcinoma and conventional adenocarcinoma of gallbladder. Asian J Surg 2023; 46:283-290. [PMID: 35422386 DOI: 10.1016/j.asjsur.2022.03.094] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 02/19/2022] [Accepted: 03/24/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Gallbladder mucinous adenocarcinoma (GBMAC) is a rare type of gallbladder malignant tumor, whereas little is known regarding the clinicopathological features and surgical outcomes of GBMAC. METHODS From January 2000 till December 2015, 54 GBMAC patients who underwent curative-intent surgical resection at our institution were retrospectively reviewed. We compared the clinicopathological features and surgical outcomes of these GBMAC patients with a relatively large cohort of surgically resected conventional gallbladder adenocarcinoma (GBAC) patients without existence of mucinous components. RESULTS The clinicopathological features of GBMAC were significantly different from conventional GBAC, including poorer tumor differentiation (P < 0.001), higher CA19-9 levels (P < 0.001), larger tumor sizes (P = 0.020), advanced AJCC tumor stage (P = 0.002), higher frequency of liver parenchyma invasion (P = 0.020), portal vein invasion (P = 0.003), lymph node metastasis (P = 0.016), lympho-vascular invasion (P < 0.001) and perineural invasion (P = 0.025). Relative to conventional GBAC patients, GBMAC patients showed significantly worse overall survival (OS) (29.0 vs 15.0 months; P < 0.001). Multivariate analysis confirmed the surgical margin (P = 0.046), tumor differentiation grade (P = 0.018), lymph node metastasis (P = 0.024), and presence of signet-ring cell component (P = 0.005) as independent prognostic factors influencing OS of patients with GBMAC. CONCLUSION GBMAC always had more aggressive biological behaviors and poor survival outcomes even after curative surgery. GBMAC patients with the presence of signet-ring cell component showed even worse survival outcome.

Abstract
PurposeOur study aims to examine the clinicopathological features, disease progression, management, and outcomes of gallbladder sarcomatoid carcinoma (GBSC) patients.MethodsBetween January 2000 and December 2020, 50 gallbladder cancer (GBC) patients who received surgical treatment and were pathologically verified as GBSC at our institution were enrolled. The clinical and pathological features and survival of these patients were retrospectively reviewed.ResultsThe median overall survival (OS) of GBSC patients was 14.5 months, and the 1-, 2- and 3-year OS rates were 68.0%, 32.0%, and 10.0%, respectively. The median progression-free survival (PFS) was 10.0 months, and the 1-, 2-, and 3-year PFS rates were 42.0%, 16.0%, and 2.0%, respectively. Patients who received radical resection had obviously better OS (18.0 vs. 7.0 months, P<0.001) and PFS (12.0 vs. 5.0 months, P<0.001) than those who underwent palliative resection. Multivariate analysis revealed that vascular invasion (P=0.033), curative operation (P<0.001) and postoperative chemotherapy (P=0.033) were independent risk factors for PFS. We further identified postoperative chemotherapy (P=0.010) and curative operation (P<0.001) as independent prognostic factors affecting the OS of GBSC patients. After curative surgery, patients who underwent S-1-based chemotherapy showed significantly longer recurrence-free survival (RFS) than those who underwent other chemotherapy regimens (20.0 vs 11.0 months, P=0.028).ConclusionGBSC patients always have aggressive biological behaviors and remarkably poor prognoses. Most GBSC patients are diagnosed in advanced stages, and timely radical operation together with postoperative chemotherapy is important. S-1-based chemotherapy may be a selectively efficient regimen to prolong the survival of GBSC patients.

Abstract
Background Previous studies have demonstrated that platelet distribution width (PDW) is a reliable predictor of prognosis of a variety of tumors. Nevertheless, the prognostic value of PDW in gallbladder carcinoma (GBC) remains unknown. We aimed to explore the correlation between PDW and prognosis in patients with GBC. Methods A total of 303 patients with GBC who underwent curative surgery between January 2005 and February 2017 were enrolled. The relationship between PDW and clinicopathological features was analyzed. Receiver operating characteristic (ROC) curve was used to identify the optimal cutoff value of PDW. The overall survival (OS) rate was estimated by Kaplan–Meier method. Meanwhile, univariable and multivariable Cox regression model were used to evaluate the risk factors for OS. Results There was significant correlation between elevated PDW and AJCC stage. In addition, survival analysis revealed that the patients with PDW>14.95 have a worse prognosis than patients with PDW\documentclass[12pt]{minimal}

Abstract
Gallbladder carcinoma is rare and difficult to detect in the early stages of the disease process, due to lack of symptoms. Sonography is typically the first modality of choice for assessing gallbladder pathology due to its high sensitivity, portability, real-time imaging capability, and non-ionizing technique. Conventional gray-scale and color Doppler sonographic imaging may be ambiguous for diagnosing solid tumors, such as gallbladder carcinoma. In this case, gallbladder carcinoma was definitively diagnosed utilizing contrast-enhanced ultrasound, allowing for quick patient treatment options and an optimal surgical outcome.

The predictive value of systemic immune inflammation index for postoperative survival of gallbladder carcinoma patients. J Surg Oncol 2021; 124:59-66.

Abstract
BACKGROUND Growing evidence indicates that systemic immune inflammation index (SII) can predict the prognosis of various solid tumors. The objective of this study aimed to investigate the efficacy of SII in predicting the prognosis of gallbladder carcinoma (GBC) patients after radical surgery. METHODS A consecutive series of 93 patients with GBC who underwent radical resection were enrolled in the retrospective study. The cutoff value for the SII was calculated using the time-dependent receiver operating characteristic (ROC) curve analysis by overall survival (OS) prediction. The associations between the SII and the clinicopathologic characteristics were analyzed using Pearson's χ2 test and Fisher's exact test. Survival curves were calculated using the Kaplan-Meier method. Univariate analysis was performed to evaluate the prognostic relevance of preoperative parameters. The multivariate Cox regression proportional hazard model was used to assess variables significant on univariate analysis. RESULTS The Kaplan-Meier survival analysis and the multivariate analysis of patients with GBC who received radical resection showed SII independently predicted OS. The univariate analysis showed that the TNM stage, SII, CA19-9, ALP, prealbumin, NLR, MLR, lymph node metastasis, and histopathological type were all associated with overall survival. In time-dependent ROC analysis, the area of the SII-CA19-9 under the ROC curve (AUC) was higher than that of the preoperative SII or CA19-9 levels for the prediction of OS. CONCLUSION Our results demonstrate that high SII was a predictor of poor long-term outcomes among patients with GBC undergoing curative surgery. SII-CA19-9 classification may be more effective in predicting the postoperative prognosis of GBC patients.

Abstract
BACKGROUND The present study was designed to study the ability of preoperative serum concentrations of the tumor-associated biomarkers carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and adjusted CA19-9 to assess the resectability of advanced gallbladder cancer (GBC). MATERIAL AND METHODS This retrospective study included patients with potentially resectable stage II-IV (AJCC 8th) GBC examined at our institution between January 2012 and December 2016. Receiver operating characteristic (ROC) curve analysis was used to determine the predictive value and optimal cut-off point of tumor-associated biomarkers for curative resection. RESULTS Pathological examination of the 309 patients included in this study found that 169 (54.7%) underwent R0 (curative) resection, whereas 121 (39.2%) underwent R1/2 (non-curative) resection, and 19 (6.1%) were unresectable. The mean serum concentrations of CEA, CA19-9 and adjusted CA19-9 were significantly lower in patients who underwent R0 resection than in the other groups. ROC curve analysis showed that adjusted CA19-9 concentration was better able to predict resectability (area under the curve, 0.774; 95% confidence interval, 0.722-0.826; P<0.001) than total bilirubin, CEA, and CA19-9 concentrations. The optimal cut-off for adjusted CA19-9 concentration was 47.63 U/mL, which had a sensitivity of 69.82%, a specificity of 75%, a positive predictive value of 77.12% and a negative predictive value of 67.31%. CONCLUSIONS Adjusted CA19-9 concentration is an easily calculated parameter superior to CA19-9 and CEA concentrations in predicting the resectability of advanced gallbladder cancer.

Abstract
Gallbladder cancer (GBC) is a rare biliary malignancy. The relationship between red blood cell distribution width (RDW) and cancer prognosis has been confirmed by many studies, however, the relationship between RDW and gallbladder cancer is rarely reported. Therefore, we aimed to assess the correlation between RDW and the advancements of GBC in this study.A retrospective study was performed on 108 GBC patients and 119 age and gender-matched individuals who were admitted to the First Affiliated Hospital of Guangxi Medical University from January 2012 to December 2018.The GBC patients had significantly higher RDW(%) levels compared to the healthy controls group (15.7 ± 2.4 vs 13.5 ± 0.6; P = .000). In addition, GBC patients with stage III+IV had higher levels of RDW(%) than stage I+II (16.1 ± 2.5 vs 14.9 ± 2.0, P = .011). Correlation analysis showed that RDW had positive correlations with TNM stage (correlation coefficient = 0.302, P = .002). The cut-off value of RDW was observed to be 14.5% in patients with GBC (area under the curve = 0.757, 95% confidence interval = 0.677-0.838, P = .000). Univariate logistic regression and multivariate logistic regression analysis showed that RDW was an independent risk factor for GBC lymph node metastasis.Our results suggest that elevated levels of RDW are independently associated with GBC patients and may serve as potential markers for the advancements of GBC.

Abstract
The neutrophil-lymphocyte ratio (NLR) is an immune response-related indicator and it is associated with poor prognosis of various cancers. The carbohydrate antigen19-9 (CA19-9) is a tumor-associated antigen and it has prognostic relevance in gallbladder carcinoma (GBC). We aimed to analyze whether preoperative NLR and serum CA19-9 were associated with outcomes of GBC patients after surgery with curative intent.Between January 2010 and May 2015, 90 resectable GBC patients who underwent curative surgery in our institution were included. All final diagnoses were confirmed by pathologic examination. The demographics, clinical, and histopathology data were analyzed. The Cox regression proportional hazard model and Kaplan-Meier method were used to assess prognostic factors.The cutoff values of 4.33 and 250.90 U/mL were defined as high NLR and high CA19-9, respectively. The univariate analyses showed that TNM stage, lymph node metastasis, the degree of tumor differentiation, margin status, combined hepatectomy, CA19-9, NLR, and PNI were all associated with overall survival (P < .05). According to the multivariable analysis, NLR (hazard ratio (HR) 3.840, 95% confidence interval (95% CI): 2.122-6.947, P < .001), CA19-9 (HR 2.230, 95% CI: 1.297-3.835, P = .004), TNM stage (HR 3.864, 95% CI: 1.819-8.207, P < .001), lymph node metastasis (HR 1.679, 95% CI: 1.005-2.805, P = .048), and margin status (HR 1.873, 95% CI: 1.063-3.300, P = .030) were independent prognostic factors. The median survival time in low NLR and CA19-9 group was better than high NLR and CA19-9 group (P < .05).The preoperative NLR and serum CA19-9 are associated with prognosis of patients with GBC. High NLR and high CA19-9 were predictors of poor long-term outcome among patients with GBC undergoing curative surgery.

Abstract
BACKGROUND Neutrophil-Lymphocyte Ratio (NLR) and Platelet-Lymphocyte Ratio (PLR) have been considered as indicators for prognosis in various cancers. However, the prognostic values of NLR and PLR have never been tested in gallbladder carcinoma (GBC) with hepatic involvement. OBJECTIVE The aim of the current study was to assess the prognostic significance of NLR, PLR, and other candidate biomarkers in GBC with liver involvement. METHODS Receiver operating characteristic (ROC) curve analyses were utilized to pinpoint the cut-off values for NLR, PLR, and Monocyte-Lymphocyte Ratio (MLR). Univariate analyses were employed to estimate the impact of NLR, PLR, MLR, and other inflammatory indexes on median survival. Multivariate analyses were used to verify the independent prognostic predictors. RESULTS Eighty four patients were enrolled from 2009 to 2017. The cut-off values for NLR, PLR, and MLR were 3.20, 117.75, and 0.25, respectively. Univariate analyses revealed that TNM stage, NLR, PLR, MLR, lactate dehydrogenase, alkaline phosphatase, and carcinoembryonic antigen were significantly associated with decreased survival in GBC with hepatic involvement. Advanced TNM stage (P< 0.001) and elevated preoperative NLR (P= 0.002) were significantly associated with lower median survival periods, as revealed by multivariate analyses. CONCLUSIONS These findings suggest that preoperative NLR may be an independent prognostic factor in evaluating prognosis in GBC with liver involvement.

Abstract
Laparoscopic surgery has been widely accepted as a feasible and safe treatment modality in many cancers of the gastrointestinal tract. However, most guidelines on gallbladder cancer (GBC) regard laparoscopic surgery as a contraindication, even for early GBC. This study aims to evaluate and compare recent surgical outcomes of laparoscopic and open surgery for T1(a,b) GBC and to determine the optimal surgical strategy for T1 GBC.The study enrolled 197 patients with histopathologically proven T1 GBC and no history of other cancers who underwent surgery from 2000 to 2014 at 3 major tertiary referral hospitals with specialized biliary-pancreas pathologists and optimal pathologic handling protocols. Median follow-up was 56 months. The effects of depth of invasion and type of surgery on disease-specific survival and recurrence patterns were investigated.Of the 197 patients, 116 (58.9%) underwent simple cholecystectomy, including 31 (15.7%) who underwent open cholecystectomy and 85 (43.1%) laparoscopic cholecystectomy. The remaining 81 (41.1%) patients underwent extended cholecystectomy. Five-year disease-specific survival rates were similar in patients who underwent simple and extended cholecystectomy (96.7% vs 100%, P = 0.483), as well as being similar in patients in the simple cholecystectomy group who underwent open and laparoscopic cholecystectomy (100% vs 97.6%, P = 0.543). Type of surgery had no effect on recurrence patterns.Laparoscopic cholecystectomy for T1 gallbladder cancer can provide similar survival outcomes compared to open surgery. Considering less blood loss and shorter hospital stay with better cosmetic outcome, laparoscopic cholecystectomy can be justified as a standard treatment for T1b as well as T1a gallbladder cancer when done by well-experienced surgeons based on exact pathologic diagnosis.

Abstract
Gallbladder cancer is the most common malignant tumor of the biliary tract. It is difficult to diagnose early due to the lack of special symptoms and physical signs. Most cases are diagnosed in advanced stages and the response to traditional chemotherapy and radiotherapy is extremely limited, with modest impact on overall survival. Despite improvements in outcome associated with extended resections, selection of patients for such extensive surgery remains controversial. In this article, we analyze and discuss the key issues about the surgical management of gallbladder cancer, with the hope of a more comprehensive recognition of this malignancy.

Abstract
Although patients with gallbladder papillary adenocarcinoma (GBPA) appear to have better prognoses than patients with other pathological subtypes of gallbladder carcinoma (GBC), the clinicopathological features and outcomes of GBPA have not been fully explored. This study therefore analyzed the clinicopathological characteristics and outcomes of GBPA.This study included 16 patients with GBPA and 101 with gallbladder adenocarcinoma (GBA) not otherwise specified (NOS), all diagnosed pathologically after surgical resection. Clinicopathological and survival data were retrospectively collected and compared. Fever was significantly more common in GBPA (7/16 vs 10/101; P = 0.000). Serum carbohydrate antigen 19-9 level was increased in 1 of 9 patients with GBPA and 39 of 76 with GBA (P = 0.022). More patients with GBPA underwent curative resection (15/16 vs 54/101; P = 0.009). Pathologically, patients with GBPA were at much earlier tumor (T) (4 in situ, 8 T1; P = 0.000) and Tumor, Node, Metastases (TNM) stages (P = 0.000). The overall 1-, 3-, and 5-year survival rates were significantly higher in patients with GBPA (100%, 76.9%, and 76.9%, respectively), than in patients with GBA (72.2%, 38.8%, and 31.0%, respectively; P = 0.001). Preoperative jaundice (odds ratio 7.69; 95% confidence interval, 1.53-38.76; P = 0.013) was a significant prognostic factor in patients with GBA, but was no longer significant when the patients with GBA and GBPA were pooled together. The clinicopathological features of patients with GBPA differed from those in patients with GBA (not otherwise specified). Pooling of patients may mask prognostic factors in each group.

BACKGROUND This report examines the patterns of presentation, prognostic factors and survival rate of all patients with gallbladder cancer (GBC) evaluated at our tertiary academic hospital over an 11-year period. METHODS A retrospective review of a prospectively collected database of all patients with GBC presenting between January 1998 and December 2008 was performed. RESULTS 102 GBC-patients were included: 69 women and 33 men (median age: 65,5 years). Forty-five patients presented with incidental gallbladder cancer (IGC) and 57 with nonincidental cancer (NIGC). Curative surgery rate was 84.4% for IGC and 29.8% for NIGC (p < 0.001). Five-year actuarial survival rate was 63.2% for patients with curative intent surgery and 0% for patients with palliative approach. Patients with IGC had a longer survival rate compared to patients with NIGC (median: 25.8 vs. 4.4 months, p < 0.0001). For patients with radical resection (42 patients), there was no difference between IGC and NIGC. The incidence of liver involvement was respectively 0%, 20.8%, 58.3%, 100% for pT1, pT2, pT3 and pT4 tumors. Univariate analysis showed that survival rate was significantly affected by perineural invasion, T, N and M-stage, R0 resection, liver involvement, CA-19.9. In multivariate analysis, liver involvement was the only independent factor. CONCLUSIONS Majority of patients with a potentially curable disease had IGC. Almost 80% of patients with NIGC presented with unresectable disease. For patients who underwent resection with curative intent, actuarial 5-year survival was 63.2%. Liver involvement was the only independent prognostic factor. All patients with IGC and a pT2 or more advanced T stage should undergo a second radical resection.

Abstract
OBJECTIVE To evaluate the prognostic factors of gallbladder carcinoma. METHODS Presentation, operative data, complications, and survival outcome were examined for 132 gallbladder carcinoma patients who underwent gallbladder surgery in our unit during 2002-2007, and follow-up results were obtained from every patient for univariate and multivariate survival analysis. RESULTS The univariate analysis showed that gallbladder lesion history, tumor cell differentiation, Nevin staging, preoperative lymph node metastasis and the surgical approach significantly correlated with the prognosis of the patients (p <0.05). The results of the multivariate analysis (Cox regression) showed that gallbladder lesion history, Nevin staging and the surgical approach were independent predicators with relative risks of 6.9, 4.4, 2.8, respectively (p=0.002, 0.003, 0.008). CONCLUSION Gallbladder lesion history, Nevin staging and the surgical approach are independent prognostic factors for gallbladder carcinoma, a rapidly fatal disease. Therefore, early diagnosis, anti-infective therapy and radical surgery are greatly needed to improve the prognosis of gallbladder carcinoma.

Abstract
RACIONAL: A despeito da sua relativa raridade, o adenocarcinoma de vesícula biliar é neoplasia que apresenta comportamento biológico agressivo. O único tratamento curativo tem sido a ressecção cirúrgica radical com margem livre. Fatores prognósticos têm sido estudados por serem importantes para identificar pacientes que podem se beneficiar de ressecção cirúrgica agressiva. OBJETIVO: Avaliar preditores prognósticos em longo prazo de pacientes com câncer da vesícula biliar. MÉTODOS: Foram identificados e retrospectivamente revisados os prontuários médicos de todos os doentes submetidos a tratamento cirúrgico que apresentavam diagnóstico histológico confirmado de adenocarcinoma de vesícula biliar durante período de 14 anos. Os dados foram submetidos à análise estatística uni e multivariada. RESULTADOS: A amostra total foi de 100 doentes. A mediana de idade foi de 71 anos (34 a 93). Houve 17 mulheres e 83 homens. A distribuição das lesões de acordo com o sistema de estadiamento TNM foi: I (n=22), II (n=59), III (n=6), IV (n=4) e desconhecido (n=9). Cinquenta e dois doentes foram submetidos à ressecção radical (R0) enquanto 48 à cirurgia paliativa (R1-R2). A morbidade global foi de 14% enquanto que a mortalidade pós-operatória (até 30º dia do pós-operatório) foi de 12 %. A taxa de sobrevida em cinco anos foi de 28% enquanto a mediana de sobrevida foi de 10 meses. A análise multivariada identificou seis fatores prognósticos: estádio T, nível sérico de CA 19.9, perfuração da vesícula biliar, embolização linfática, coorte cirúrgico histórico e linfadenectomia hilar. CONCLUSÃO: O tratamento do câncer de vesícula biliar apresenta alta morbimortalidade. Os fatores prognósticos foram: estádio T, nível sérico de CA 19.9, perfuração da vesícula biliar, embolização linfática, coorte cirúrgico histórico e linfadenectomia hilar.

Abstract
OBJECTIVE The objective of this study was to investigate whether radical surgical treatment can be associated with reasonable survival for patients with Stage IV gallbladder cancer with distant lymph node metastasis. METHODS Fifty-five patients (20 men and 35 women) with complete clinical and follow-up data for Japanese Society of Biliary Surgery TNM system Stage IV gallbladder cancer were included in our study. Patients were divided into three treatment groups for clinical analysis: Group A (radical resection, n = 24), Group B (chemotherapy, n = 8) and Group C (other palliative treatment, n = 23). RESULTS The survival rate in Group A was significantly higher when compared with Groups B (P=0.008) and C (P=0.004). Moreover, the prognosis of patients with distant lymph node metastasis (Group A2, Japanese Society of Biliary Surgery N3; American Joint Committee on Cancer M1) was significantly worse versus those with local lymph node metastasis (Group A1, Japanese Society of Biliary Surgery N1-N2; American Joint Committee on Cancer N1) (P=0.007). Most importantly, no significant difference in the survival rate was observed between patients in Group A2 and Groups B (P = 0.47) or C (P = 0.74). CONCLUSIONS Radical resection might result in a reasonable prognosis for gallbladder cancer patients with local metastasis of the lymph nodes (Japanese Society of Biliary Surgery N1-N2), but was not effective when distant lymph nodes (Japanese Society of Biliary Surgery N3) were involved.

Abstract
BACKGROUND The prognosis for patients with advanced gallbladder carcinoma is dismal despite aggressive surgical resection. The aim of this study is to determine useful prognostic factors for patients with gallbladder carcinoma following aggressive surgical resection. METHODS Medical records of 62 patients with gallbladder carcinoma who underwent surgical resection were retrospectively reviewed. Univariate and multivariate models were used to analyze the effect of clinicopathological factors on long-term survival. RESULTS According to the UICC staging system, ten (16%), 11 (18%), eight (13%), 16 (25%), nine (15%), and eight patients (13%) were diagnosed with stages I, II, IIIA, IIIB, IVA, and IVB disease, respectively. Partial hepatectomy and pancreatoduodenectomy were performed for 43 (69%) and 11 (18%) patients, respectively. Overall survival rates of all 62 and 41 patients with UICC stages III and IV disease were 71% and 56% at 1 year, 48% and 23% at 3 years, and 48% and 23% at 5 years, respectively (median survival time, 15.8 and 12.7 months, respectively). Multivariate analysis revealed that independent prognostic factors included tumor differentiation (p = 0.006), hepatic invasion (p = 0.002), lymph node metastasis (p = 0.009), and surgical margin status (p = 0.002) for all patients, and adjuvant chemotherapy (p = 0.005), tumor differentiation (p = 0.008), hepatic invasion (p = 0.001), and surgical margin status (p = 0.022) for patients with UICC stages III and IV disease. CONCLUSIONS R0 resection and adjuvant chemotherapy are significant prognostic factors in advanced gallbladder carcinoma and should be performed to improve survival.

Abstract
Cancer of the gallbladder, a rare entity with a poor prognosis, is often discovered incidentally during or after cholecystectomy. It tends to disseminate early via lymphatic, peritoneal, endobiliary, and hematogenous pathways. Diagnosis is made intra-operatively in only a quarter of cases, by examination of the opened cholecystectomy specimen in the operating room by the surgeon; this procedure should be routine. For incidentally-discovered cancers, survival was 28% at five years. Prognostic factors include age, TNM stage, gallbladder perforation during cholecystectomy and less-than-optimal resection at re-operation. Whether the laparoscopic route for the initial cholecystectomy has an impact on survival remains a subject of debate. R0 surgery is the only potentially curative treatment: simple cholecystectomy with clear margins is adequate resection for stage T1a tumors; extended cholecystectomy with lymphadenectomy and possibly resection of the bile duct is required for more advanced stages. After curative resection, neo-adjuvant or adjuvant chemotherapy and radiotherapy have not, so far, proven effective. Improvement of surgical practices (systematic review of cholecystectomy specimens in the OR, prevention of gallbladder perforation with bile spillage during surgery, early re-intervention for optimal resection) could improve the prognosis of these cancers.

Abstract
AIM: To evaluate the efficacy of simple and extended cholecystectomy for mucosa (T1a) or muscularis (T1b) gallbladder (GB) cancer.
METHODS: Original studies on simple and extended cholecystectomy for T1a or T1b GB cancer were searched from MEDLINE (PubMed), Cochrane Library, EMBase, and CancerLit using the search terms of GB, cancer/carcinoma/tumor/neoplasm.
RESULTS: Twenty-nine out of the 2312 potentially relevant publications met the eligibility criteria. Of the 1266 patients with GB cancer included in the publications, 706 (55.8%) and 560 (44.2%) had T1a and T1b GB cancer, respectively. Simple cholecystectomy for T1a and T1b GB cancer was performed in 590 (83.6%) and 375 (67.0%) patients, respectively (P < 0.01). In most series, the treatment of choice was simple cholecystectomy for T1a GB cancer patients with a 5-year survival rate of 100%. Lymph node metastasis was detected in 10.9% of the T1b GB cancer patients and in 1.8% of the T1a GB cancer patients, respectively (P < 0.01). Eight patients (1.1%) with T1a GB cancer and 52 patients (9.3%) with T1b GB cancer died of recurrent GB cancer (P < 0.01).
CONCLUSION: Simple cholecystectomy represents the adequate treatment of T1a GB cancer. There is no definite evidence that extended cholecystectomy is advantageous over simple cholecystectomy for T1b GB cancer.

Abstract
BACKGROUND Depth of tumor invasion is an important prognostic factor for gallbladder cancer. The aim of this study was to investigate the clinicopathological prognostic factors of T2 gallbladder cancer. METHODS We retrospectively reviewed the clinicopathological data and survival for 83 patients with T2 gallbladder cancers who underwent surgical resection between January 1995 and December 2007. RESULTS The overall survival rates were 48.9% at 3 years and 29.3% at 5 years. Univariate analysis revealed that R0 resection (P < 0.001), extended surgery (P = 0.028), lymph node dissection (P = 0.024), non-infiltrative tumors (P = 0.001), well differentiation (P = 0.001), absence of lymphatic (P = 0.025), perineural (P = 0.001), and vascular (P = 0.025) invasion, absence of lymph node metastasis (P = 0.001), negative resection margin (P = 0.016), and stage (P = 0.002) were significantly better predictors for survival. A significant difference in survival between Rx and R1 was not found. R0 resection, lymph node dissection, well differentiation, and absence of perineural and vascular invasion were significantly independent prognostic factors for overall survival. Recurrence occurred in 48 patients (57.8%). Age older than 65 years, R0 resection, non-infiltrative tumors, and good differentiation were significant independent predictors of disease-free survival by multivariate analysis. CONCLUSIONS For T2 tumors, radical surgery including lymph node dissection should be performed to achieve R0 resection. Tumors with infiltrative types and suspicious lymph node metastasis in the intraoperative findings were candidates for aggressive surgical management to improve patient survival.

Abstract
BACKGROUND Gallbladder cancer is the most common malignancy of the biliary tract. Radical surgery (including liver resection and regional lymphadenectomy) is applied for some gallbladder cancers, but the benefits of these procedures are unproven. For patients with T1b cancers discovered incidentally on cholecystectomy specimens, the utility of radical surgery remains debated. METHODS A decision analytic Markov model was created to estimate and compare life expectancy associated with management strategies for a simulated cohort of patients with incidentally discovered T1b gallbladder cancer after routine cholecystectomy. In one strategy, patients were treated with no additional surgery; in another, patients were treated with radical resection. The primary (base-case) analysis was calculated based on a cohort of 71-year-old females and incorporated best available input estimates of survival and surgical mortality from the literature. Sensitivity analysis was performed to assess the effects of model uncertainty on outcomes. RESULTS In the base-case analysis, radical resection was favoured over no further surgical resection, providing a survival benefit of 3.43 years for patients undergoing radical resection vs. simple cholecystectomy alone. Sensitivity analysis on the age at diagnosis demonstrated that the greatest benefit in gained life-years was achieved for the youngest ages having radical resection, with this benefit gradually decreasing with increasing age of the patient. High peri-operative mortality rates (>/=36%) led to a change in the preferred strategy to simple cholecystectomy alone. CONCLUSIONS Decision analysis demonstrates that radical resection is associated with increased survival for most patients with T1b gallbladder cancer.

Abstract
BACKGROUND Despite its rarity, gallbladder cancer is an aggressive type of neoplasia with a very poor prognosis. The best resection for oncological purposes continues to be right hepatectomy extended to segment IV. However, bisegmentectomy IV-V is becoming an interesting alternative because of greater preservation of the parenchyma. AIM To report the early and late results from bisegmentectomy IV-V in cases of carcinoma of the gallbladder. METHODS A series of seven cases of invasive carcinoma is presented (six women and one man). These patients underwent bisegmentectomy IV-V at the General Surgery Service of the Teaching Hospital of the ABC Medical School, Santo André, SP, Brazil. The study was conducted between 2002 and 2006. The patients ages ranged from 52 to 72 years. The diagnosis was preoperative (radiological) in five cases, which were all confirmed by intraoperative frozen-tissue examination, while in two cases the diagnosis was postoperative, following open cholecystectomy. RESULTS The duration of the operation ranged from 180 to 340 minutes. The quantity of intraoperative bleeding ranged from 200 to 1500 mL. There were two major complications but no mortality. Six patients did not present any recurrence over the course of 3 to 30 months of follow-up. CONCLUSION Bisegmentectomy IV-V may constitute a curative surgical alternative for treating gallbladder cancer. This procedure presents acceptable morbidity and mortality.

Abstract
BACKGROUND Incidental gallbladder carcinoma (IGBC) is a carcinoma first detected by the pathologist. The indication for cholecystectomy is a benign disease. The indication for immediate re-resection (IRR) in the case of T1b incidental gallbladder carcinoma (IGBC) is debated in the literature, and different recommendations often are drawn on the basis of data collected from only small groups. However, the management of IGBC is difficult because no guidelines have been established. This study aimed to determine whether T1b IGBC actually benefits from an IRR. METHODS A registry was founded in 1997 for prospective recording of all IGBCs in Germany. All the patients who had a re-resection in this study were treated according to the effective guidelines in Germany. This study analyzes 502 cases of IGBC. Kaplan-Meier curves were used to determine whether an IRR improves the survival of patients with T1 and T1b IGBC. RESULTS No benefit was found for 5 of the 21 T1a patients who had an IRR, but 23 of the 72 T1b patients who had an IRR experienced a significant benefit. The rate of tumor recurrence was three times lower in the T1b group that underwent IRR. CONCLUSION An IRR should be highly recommended for patients with IGBC in the T1b stage.

Abstract
BACKGROUND Gallbladder cancer (GC) is a relatively rare but highly lethal neoplasm. We review the epidemiology, etiology, pathology, symptoms, diagnosis, staging, treatment, and prognosis of GC. METHOD A Pubmed database search between 1971 and February 2007 was performed. All abstracts were reviewed and articles with GC obtained; further references were extracted by hand-searching the bibliography. The database search was done in the English language. RESULTS The accurate etiology of GC remains unclear, while the symptoms associated with primary GC are not specific. Treatment with radical cholecystectomy is curative but possible in only 10% to 30% of patients. For patients whose cancer is an incidental finding on pathologic review, re-resection is indicated, where feasible, for all disease except T1a. Patients with advanced disease should receive palliative treatment. Laparoscopic cholecystectomy is contraindicated in the presence of GC. CONCLUSION Prognosis generally is extremely poor. Improvements in the outcome of surgical resection have caused this approach to be re-evaluated, while the role of chemotherapy and radiotherapy remains controversial.

Abstract
BACKGROUND Radical surgery is the only curative treatment for carcinoma of gallbladder. This study aimed to evaluate the outcome of patients with carcinoma of gallbladder managed in a single institution over 16 years. METHODS From April 1988 to November 2003, 86 patients (29 males, 57 females) were diagnosed to have carcinoma of gallbladder. Tumor staging, treatment modalities and clinical outcome of these patients were evaluated. Thirty-two patients (37%) had early stage (TNM stage I or II) disease whereas 54 patients (63%) had advanced stage (TNM stage III or IV) disease. Curative treatment by surgical resection was performed in 23 patients (27%). RESULTS Overall survival was significantly better in patients with curative treatment (1-year: 85%; 2-year: 63%; 3-year: 55%) than those with palliative treatment (1-year: 11%; 2-year: 3%; 3-year: 0%; P < 0.01). Using Cox regression model, curative treatment was the only independent prognostic factor affecting overall survival of patients with carcinoma of gallbladder. A significantly better survival was associated with curative treatment compared with palliative treatment in patients with incidental gallbladder cancer. The median survival was 33.9 months for the curative treatment group versus 3 months for the palliative treatment group (P = 0.0001). CONCLUSION Favorable survival outcome can be achieved in patients with carcinoma of gallbladder after curative resection.

Abstract
OBJECTIVE The aim of this study was to determine which T stages of incidental gallbladder carcinoma (IGBC) actually benefit from an early reresection (ERR). BACKGROUND The IGBC is a carcinoma first detected by the pathologist. The indication for the cholecystectomy was a benign disease. The indication for an ERR is debated in the literature, and different recommendations are often drawn based on data collected from only small groups. METHODS A register was founded in 1997 to prospectively record all IGBCs in Germany. All the patients who had a reresection in this study were treated according to the German Guidelines of Surgery and Oncology. This study analyzes 439 cases of IGBC. RESULTS There was a significant benefit for the 85 of 200 T2 patients who did have an ERR. There was no benefit though for the 32 of 85 T3 patients who did have an ERR. There is a significantly better survival rate for T2 patients with negative lymph nodes, and there is a trend for better survival for T3 patients with negative lymph nodes. CONCLUSION An ERR should be highly recommended for patients with IGBC in the T2 stage, because it improves their survival positive. Without an ERR, it is almost impossible to definitively determine the nodal status or to obtain exact staging for estimating the prognosis.

Abstract
BACKGROUND/PURPOSE Gallbladder cancer (GBC) is a rare malignancy with poor overall prognosis. Simple cholecystectomy is curative if the cancer is limited to mucosa. We aimed here to investigate the need for routine histological examination of gallbladder. METHODS We carried out a retrospective review of 2890 final pathology reports of processed gallbladder specimens following cholecystectomy due to gallstones disease. The review covered the 10-year period from 1994 to 2004. The notes of all cases of gallbladder cancer were scrutinized, with particular emphasis on presentation, preoperative diagnostic tools using abdominal ultrasound and computed tomography scan, operative findings, and the histology results. RESULTS Gallbladder cancer (GBC) was detected in five specimens (0.17%), dysplasia in six (0.2%), and secondaries to gallbladder in three (0.1%). Histological findings confirmed gallstone disease in 97% and rare benign pathology in 3%. The median age of patients with GBC was 61 years (range, 59-84 years). In all five patients, cancer was isolated from thickened fibrotic wall on macroscopic appearance and spread through all layers of the gallbladder wall. The percentage of thickened-wall gallbladder in this study was 38.02% and the cancer incidence in the thickened wall was 0.45%. CONCLUSIONS A selective policy rather than routine histological examination of nonfibrotic or thickened-wall gallbladder has to be considered. This will reduce the burden on pathology departments, with significant cost savings.

Abstract
Gallbladder cancer is a relatively unusual, but often lethal malignancy. Surgical management has historically been palliative only; however, with the advancement of techniques in hepatobiliary surgery, varying extents of surgical intervention have been advocated for cure. This article reviews the current approach to the surgical management of gallbladder cancer and discusses the rationale for an aggressive approach to this disease.

Abstract
Biliary tract cancers are uncommon malignancies arising from biliary epithelium intrahepatically (peripheral cholangiocarcinoma), in the extrahepatic bile duct, the gall bladder and the ampulla of Vater. Treatment has been challenging because of late presentation, complex surgery, complex biliary obstruction with jaundice and a paucity of high quality data on which to establish standard care. With improvements in imaging, biliary stenting, surgical management and the establishment of a national investigational programme we hope to define the modern management of biliary tract cancers and enable a platform for further research.

Abstract
BACKGROUND The role of radical resection for gallbladder cancer is an ongoing area of debate. In this review, we present our experience managing gallbladder cancer at a tertiary center by using an aggressive surgical approach for T2 or greater disease, reserving simple cholecystectomy only for T1 lesions. METHODS Seventy-six patients with histologically confirmed gallbladder cancer were identified from our cancer registry. Estimated survival distributions were calculated by the Kaplan-Meier method, and comparisons were made by using the log-rank test. The Cox proportional hazards model was used to determine the effect on survival of T stage, nodal status, age, and margins. RESULTS Sixty-four patients were assessable for this study. Simple cholecystectomy was the only procedure performed in 10 T2 and 15 T3 cases. Radical cholecystectomy was performed as the primary procedure in two T2, two T3, and six T4 cases. Radical re-resection was accomplished in seven T2 and two T3 cases. Excluding the T4 group, there was a significant survival advantage (P = .007) for the radical resection group (n = 13; median survival not yet reached) compared with the simple cholecystectomy group (n = 25; median survival, 17 months; 95% confidence interval, 7-27 months). Analysis of the 13 T2 and T3 patients who underwent radical resections revealed that the radical re-resection group (n = 9) had an overall survival similar to that of the primarily resected group (n = 4). All T2N(+) and T3N(-) patients are still alive and disease free after 5 years of follow-up, whereas none of the T3N(+) or T4 patients survived beyond 24 months. Increasing T stage and age (>65 years) were independent predictors of a poor prognosis. CONCLUSIONS Radical resection for T2 and T3 disease resulted in a significant survival advantage compared with simple cholecystectomy. Patients who undergo radical re-resection after an incidentally discovered gallbladder cancer experience the same survival benefit as primarily resected patients. Radical resection for T2N(-), T2N(+), and T3N0 cases can achieve long-term survival. Conversely, the prognosis for T3N(+) and T4 patients is poor, and improved outcome for this group will likely depend on the development of multi-institutional neoadjuvant clinical trials that can identify effective systemic regimens.

Abstract
The present study aimed to clarify the efficacy of extensive surgery, including pancreas head resection, for more complete lymphadenectomy in the treatment of gallbladder carcinoma. The study involved retrospective analyses of 65 consecutive patients with gallbladder carcinoma who underwent surgical resection between 1982 and 2003. Of these 65 patients, 41.5% displayed node-positive disease and among them 23.1% had positive para-aortic nodes. Of six node-positive 5-year survivors, five underwent pancreatoduodenectomy combined with S4aS5 hepatic subsegmentectomy. The 5-year survival rates were 76.2% for pN0, 30.0% for pN1, 45.8% for pN2, and 0% for pM1[lymph], respectively. Significant differences existed in survival rates. Postoperative recurrence was observed in 24.1% (13/54) of patients who underwent R0 resection. Of the four patients who displayed lymph node recurrence, two had pericholedocal and/or posterior pancreatoduodenal lymph node metastasis at the time of surgery and underwent pancreas-preserving regional lymphadenectomy. These results suggest that extensive resection, including resection of the pancreatic head, is effective in selected patients with up to pN2 lymph node metastasis, as long as complete removal of the cancer can be achieved. Pancreatoduodenectomy combined with S4aS5 hepatic subsegmentectomy should be considered when lymph node metastasis is obvious and the patient is in good condition.

Abstract
AIMS To report the surgical management of carcinoma of the gallbladder. METHODS A retrospective study in 65 patients who underwent simple (SC) or extended (EC) cholecystectomy for gallbladder carcinoma. RESULTS 28 patients underwent extended cholecystectomy (EC) and 37 had simple cholecystectomy (SC). The multivariate analysis showed that lymph-node status (positive vs negative, p=0.001, Hazard Ratio [HR]:14.2, 95% Confidence Interval [CI]:3.1-62.8) and type of surgery (SC vs EC, p=0.01, HR:10.2, 95% CI:1.7-62.8) were the most important prognostic factors related to death. This analysis indicated that EC in those with pT(2) or pT(3) was associated with a reduce hazard of death by 90% in the follow-up period. CONCLUSIONS In gallbladder cancer patients who diagnose after simple cholecystectomy, those with pT(1) with clear margins need no further surgery. In patients with pT(2) or pT(3) incidental carcinoma, the completion radical re-operation is the only chance for long-term survival.
