Abstract
Introduction Gallbladder cancer (GBC) is one of the most common and aggressive malignancies of the Indo-Gangetic plains. Despite its widespread use in GBC cases, the role of 18-flurodeoxyglucose positron emission tomography-computed tomography ( 18 FDG PET-CT) in the management of this disease is not well defined. In our study, we present the practice trends of the utilization of this investigative modality in our hospital and its benefits in aiding diagnosis, staging, and surveillance for recurrence. Materials and Methods All cases of suspected and biopsy-proven GBCs who underwent PET-CT at our institute between 2016 and 2019 were retrospectively evaluated for the indication of PET-CT testing and its impact on the management of the case. The indications were classified into three categories: (i) staging and metastatic workup, (ii) response assessment post-chemotherapy, and (iii) post-therapy surveillance of patients. Results A total of 79 PET-CT scans were carried out during the study period. PET-CT was used for less than one-third of the total patients of GBC presenting at our center. Initial staging and workup (49%) was the most common indication followed by surveillance (28%) and response assessment (23%). PET-CT had a substantially better sensitivity in detecting distant metastases compared to conventional imaging in both initial workup and during follow-up. PET-CT provided additional information in 42% scans that led to change in the management of the patient. As a response assessment tool PET-CT aided not only in evaluating efficacy of therapy but also for documenting progressive disease for patients on therapy. Conclusion PET-CT is a valuable tool to not only rule out metastatic disease while selecting patients for surgery but also for post-therapy surveillance for recurrence in patients of GBC. Larger prospective studies may help in finally elucidating the exact role of PET-CT in this disease.

Abstract
Objectives Although guidelines recommend extended cholecystectomy for T2 gallbladder cancer (GBC), the optimal hepatectomy strategy remains controversial. The study aims to compare the prognosis of T2 GBC patients who underwent wedge resection (WR) versus segment IVb and V resection (SR) of the liver. Methods A specific search of online databases was performed from May 2001 to February 2023. The postoperative efficacy outcomes were synthesized and meta-analyses were conducted. Results A total of 9 studies involving 2,086 (SR = 627, WR = 1,459) patients were included in the study. The primary outcomes included disease-free survival (DFS) and overall survival (OS). For DFS, the 1-year DFS was statistically higher in patients undergoing SR than WR [risk ratio (RR) = 1.07, 95% confidence interval (CI) = 1.02-1.13, P = 0.007]. The 3-year DFS (P = 0.95), 5-year DFS (P = 0.77), and hazard ratio (HR) of DFS (P = 0.72) were similar between the two groups. However, the 3-year OS was significantly lower in patients who underwent SR than WR [RR = 0.90, 95% CI = 0.82-0.99, P = 0.03]. Moreover, SR had a higher hazard HR of OS [HR = 1.33, 95% CI = 1.01-1.75, P = 0.04]. No significant difference was found in 1-year (P = 0.32) and 5-year (P = 0.9) OS. For secondary outcomes, patients who received SR tended to develop postoperative complications (POC) [RR = 1.90, 95% CI = 1.00-3.60, P = 0.05]. In addition, no significant differences in intrahepatic recurrence (P = 0.12) were observed. Conclusions In conclusion, SR can improve the prognosis of T2 GBC patients in DFS. In contrast to WR, the high HR and complications associated with SR cannot be neglected. Therefore, surgeons should evaluate the condition of the patients and take their surgical skills into account when selecting SR.

Abstract
INTRODUCTION T2 gallbladder cancer (GBC) is the only stage showing a survival benefit after complete surgical resection, but recurrence rates remain high. Although human epidermal growth factor receptor 2 (HER2) has emerged as a therapeutic target, its role in T2 GBC remains unclear. This study investigated the status and prognostic impact of HER2 expression on T2 GBC. MATERIALS AND METHODS HER2 expression and amplification were detected by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), respectively, in 90 patients with T2 GBC who underwent radical cholecystectomy. We evaluated HER2 status according to the breast and gastric cancer guidelines and analyzed the effect of relevant prognostic factors on survival. RESULTS HER2 positive status was observed in 11.11% (10/90) and 8.89% (8/90) of cases based on gastric and breast cancer guidelines, respectively. Poor differentiation and a higher level of perineural invasion were independent prognostic factors of disease-free survival (DFS). Old age, male sex, presence of lymph node metastasis, poor differentiation, high levels of perineural invasion, and HER2 positivity based on breast cancer guidelines were identified as independent prognostic factors of overall survival (OS). Patients with HER2-positive T2 GBC according to breast cancer guidelines had worse OS. CONCLUSIONS HER2 positivity based on breast- but not gastric-cancer guidelines was associated with poorer survival. These results provide a criterion for the evaluation of HER2 and a rationale for therapeutic strategies targeting HER2 in T2 GBC.

Abstract
BACKGROUND Peri-neural invasion (PNI) in gallbladder carcinoma (GBC) has been demonstrated as a vital prognostic factor. However, whether PNI in patients with GBC can be regarded as a surgical indication of bile duct resection (BDR) remains controversial. METHODS GBC patients with pathologically-confirmed PNI between September 2010 and September 2020 were retrospectively reviewed. Comparative analyses were performed in patients with PNI according to the performance of BDR. SPSS 25.0 software and Graph pad PRISMA 7.0 software were used for statistical analyses. RESULTS A total of 70 patients GBC patients with PNI were incorporated. The results of comparative analyses indicated that patients who received BDR were generally in a more advanced stage and often required a more extended radical cholecystectomy. Higher incidences of preoperative jaundice (48.6% vs 2.9%, P < 0.0001), major hepatectomy (25.7% vs 8.6%, P = 0.055), combined multi-visceral resections (48.6% vs 5.7%, P < 0.0001), combined major vascular reconstruction (22.9% vs 2.9%, P = 0.014), and a lower R0 rate (68.6% vs 88.6%, P = 0.039) were detected in patients who received BDR. Even after propensity score matching (PSM), BDR still had no significant survival advantage but only increased the length of postoperative stay and the frequency of postoperative morbidities. CONCLUSION BDR seemed to have no significant survival advantage in GBC patients with PNI and was only correlated with a longer postoperative hospital stay and a higher rate of morbidities. PNI should not be regarded as a surgical indication of BDR in patients with GBC.

Comparison of the Oncological Outcomes of Open versus Laparoscopic Surgery for T2 Gallbladder Cancer: A Propensity-Score-Matched Analysis. J Clin Med 2022; 11:jcm11092644. [PMID: 35566770 PMCID: PMC9099510 DOI: 10.3390/jcm11092644] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 04/25/2022] [Accepted: 05/06/2022] [Indexed: 02/01/2023] Open
Abstract
Although laparoscopic treatment for T1 gallbladder cancer (GBC) has been described previously, the differences in oncologic outcomes between laparoscopic and conventional open surgery for T2 GBC have not been investigated. We aimed to assess the role of laparoscopic surgery using retrospectively collected data for 81 patients with T2 GBC who underwent surgical resection between January 2010 and December 2017. Eligible patients were classified into “laparoscopic” and “open” groups. Propensity-score matching was performed in a 1:1 ratio. The effects of surgery type on surgical and oncological outcomes were investigated. After propensity-score matching, 19 patients were included in the open and laparoscopic surgery groups. The median follow-up durations were 70 and 26 months in the open and laparoscopic groups, respectively. The operative time (316.8 ± 80.3 vs. 218.9 ± 145.0 min, p = 0.016) and length of postoperative hospital stay (14.4 ± 6.0 vs. 8.4 ± 5.9 days, p = 0.004) were significantly shorter in the laparoscopic group. The three-year overall (86.3% vs. 88.9%, p = 0.660) and disease-free (76.4% vs. 60.2%, p = 0.448) survival rates were similar between the groups. Propensity-score matching showed that laparoscopic surgery for T2 GBC yielded similar long-term oncological outcomes and favorable short-term outcomes in comparison with open surgery. Laparoscopic treatment should be considered in patients with T2 GBC.

Abstract
OBJECTIVE To systematically evaluate the clinicopathological and prognostic value of extra-hepatic bile duct resection (EHBDR) in the surgical management of patients with gallbladder carcinoma (GBC), especially in non-jaundiced patients. METHODS PubMed, EMBASE and the Cochrane Library were searched up to March 1st 2021 for comparative studies between bile duct resected and non-resected groups. RevMan5.3 and Stata 13.0 software were used for the statistical analyses. RESULTS EHBDR did not correlate with a better overall survival (OS) (P = 0.17) or disease-free survival (P = 0.27). No survival benefit was also observed in patients with T2N1 (P = 0.4), T3N0 (P = 0.14) disease and node-positive patients (P = 0.75), rather, EHBDR was even harmful for patients with T2N0 (P = 0.01) and node-negative disease (P = 0.02). Significantly higher incidences of recurrent disease (P = 0.0007), postoperative complications (P < 0.00001) and positive margins (P = 0.02) were detected in the bile duct-resected group. The duration of postoperative hospital stay between the two groups was comparable (P = 0.58). Selection bias was also detected in our analysis that a significantly higher proportion of advanced lesions with T3-4 or III-IV disease was observed in the bile duct-resected group (P < 0.00001). EHBDR only contributed to a greater lymph yield (P = 0.01). CONCLUSION EHBDR has no survival advantage for patients with GBC, especially for those with non-jaundiced disease. Considering the unfairness of comparing OS between jaundiced patients receiving EHBDR with non-jaundiced patients without EHBDR, we could only conclude that routine EHBDR in non-jaundiced patients is not recommended and future well-designed studies with more specific subgroup analyses are required for further validation.

Abstract
Backgrounds/Aims Extended cholecystectomy (EC) is the mainstay of treatment in most patients with potentially curable gallbladder cancer (GBC). The optimum extent of hepatic resection in EC is debatable. Methods This retrospective study was conducted on patients with GBC who received EC from May 2009 to February 2019. Based on the extent of hepatic resection, patients were divided into ECB (EC involving bi-segmentectomy s4b&5) and ECW (EC involving wedge hepatic resection) groups. Patients with T1 GBC, T4 GBC, and benign diseases were excluded. Post-exclusion, both groups were matched for T and N stage. Matched groups were then compared. Results Out of a total of 161 patients who received EC, 86 patients had ECB and 75 patients had ECW. After exclusion and matching, both ECB and ECW groups had 35 patients. Their demographic and clinical profiles were comparable. Surgical blood loss (p = 0.005) and postoperative complication rate (p = 0.035) were significantly less in the ECB group. For ECB vs. ECW, mean recurrence-free survival (RFS) was 58.2 months vs. 42.3 months (p = 0.264) and overall survival (OS) was 61.5 months vs. 43.4 months (p = 0.161). On univariate analysis, higher T and N stages were associated with poor prognosis. On multivariate analysis, higher T stage, N stage, and American Society of Anaesthesiologists grade were associated with poor RFS and OS. Conclusions The survival after ECB for T2 and T3 GBC was not significantly superior to that after ECW. However, surgical blood loss and postoperative complications were lower following ECB.

Abstract
Extensive surgery is the mainstay treatment for gallbladder cancer and offers a long-term survival benefits to the patients. However, the optimal extent of surgery remains debatable. We aimed to perform a meta-analysis of hepatectomy and no hepatectomy approaches in patients with T2 gallbladder cancer. We searched the following electronic databases for systematic literature: PubMed, Google Scholar, and the Cochrane Library. We selected studies that compared patients with T2 gallbladder cancer who underwent hepatectomy with those who did not. While the long-term overall survival (OS) and disease-free survival (DFS) were the primary outcomes, perioperative morbidity and mortality were the secondary outcome. We analysed over 18 studies with 4,587 patients. Of the total patients, 1,683 and 1,303 patients underwent hepatectomy and no hepatectomy, respectively. The meta-analysis revealed no significant difference between the hepatectomy and no hepatectomy groups, in terms of the overall morbidity (risk ratio [RR] = 1.85, 95% confidence interval [CI] = 0.66-5.20) and 30-day mortality (RR = 0.9, 95% CI = 0.1-8.2). The results were comparable in terms of the OS (RR = 0.76, 95% CI = 0.57-1.01), (HR = 0.74, 95% CI = 0.49-1.12), and DFS (RR = 0.99, 95% CI = 0.88-1.11). In conclusion, the perioperative and long-term outcomes of hepatectomy and no hepatectomy approaches were comparable. Hepatectomy may not be required in T2 gall bladder cancer if the preoperative evaluation confirms the depth of the tumour in the perimuscular connective tissue and the intraoperative frozen sections confirm microscopic negative margins. Likewise, for those whom gall bladder cancer was diagnosed from the pathological report after simple cholecystectomy, further hepatectomy may not necessary.

Abstract
Background Gall bladder carcinoma (GBC) is the most common malignancy of the biliary tract. Being known for its geographical and racial variations, and compared with the global statistics, its incidence is higher in the Indian subcontinent, mainly in the northern and eastern regions, accounting for 80 to 95% of cases. Aims and Objectives This study was conducted to evaluate the clinic-pathological spectrum and expression of EGFR and HER-2/NEU in GBCs and to understand their relation to prognosis, paving the way for targeted therapies for better treatment outcomes and patient survival. Materials and Methods This is a prospective study performed in a tertiary care hospital in 30 resected specimens of GBC cases recorded in our Department of Pathology from November 2017 to November 2019. Clinical history including the radiological reports and demographic parameters were included in the study pro forma. Immunohistochemical (IHC) staining for EGFR and HER-2/NEU was performed on all the selected cases. Clinicopathologic parameters like age, sex, histologic type, perineural, and lymphovascular invasion were compared and correlated with EGFR and HER-2/NEU status. Results Expression of EGFR was found in 93.33% of cases, which showed a highly significant correlation with histological tumor type ( p = 0.000). HER-2/NEU expression was found in 56.66% of cases, which also showed a significant correlation with histological tumour type ( p = 0.021). We found most of the cases with strong EGFR immunoreactivity (3+) were poorly differentiated tumors and most of the cases showing weak immunoreactivity for EGFR (1+) were well-differentiated. Conversely, in case of HER-2/NEU immunoreactivity, strong staining (3+) was seen in well-differentiated tumors and weak staining (1+) in poorly differentiated tumors. A significant correlation was also found between EGFR and HER-2/NEU expression ( p = 0.000) and between cholelithiasis and EGFR expression ( p = 0 .033). Conclusion EGFR is expressed in most cases of GBC. Its expression is more in poorly differentiated carcinomas as compared to the well-differentiated carcinomas, whereas HER-2/NEU expression is more in well-differentiated carcinomas. Therefore, they may serve as independent prognostic factors and also as targets for molecular therapy in GBCs.

A simple method for diagnosing gallbladder malignant tumors with subserosa invasion by endoscopic ultrasonography. BMC Cancer 2021; 21:288.

Abstract
BACKGROUND If the depth of gallbladder malignant tumor (GBMT) invasion is deeper than the subserosa (ss), cholecystectomy is insufficient. In past reports that used endoscopic ultrasonography (EUS) to diagnose the depth of tumor invasion, it was difficult to diagnose GMBT invasion in the ss without a narrow or disrupted lateral hyperechoic layer (LHEL). Therefore, we developed a simple preoperative method to diagnose GBMTs with ss invasion. METHODS Forty-nine GBMT patients who underwent both EUS and surgery were enrolled: 15 patients whose tumors invaded the mucosa (m) or muscularis propria (mp) were classified as the "shallow group", and 34 patients whose tumors invaded the ss were classified as the "deep group". The EUS findings were compared between the two groups. RESULTS An irregular (narrow or thickened) LHEL was significantly more frequently observed on EUS in the deep group than in the shallow group. The diagnosis of ss invasion based on an irregular LHEL had the highest sensitivity and accuracy among the EUS imaging parameters (sensitivity 97.1% (33/34), specificity 86.7% (13/15), accuracy 93.8% (46/49)). When the deep group was limited to patients with a tumor depth of ss, the results were similar. When an irregular LHEL was used, the diagnostic accuracy of GBMTs with ss invasion was not significantly different between EUS specialists and beginners. CONCLUSIONS The observation of an irregular (thickened or narrow) LHEL observed on EUS could be a reliable and simple method of diagnosing GBMTs with ss invasion and could contribute to choosing an appropriate surgical method.

Abstract
Published data on survival of T2 gallbladder carcinoma (GBC) from different countries show a wide range of 5-year survival rates from 30-> 70%. Recently, studies have demonstrated substantial variation between countries in terms of their approach to sampling gallbladders, and furthermore, that pathologists from different continents apply highly variable criteria in determining stage of invasion in this organ. These findings raised the question of whether these variations in pathologic evaluation could account for the vastly different survival rates of T2 GBC reported in the literature. In this study, survival of 316 GBCs from three countries (Chile n = 137, South Korea n = 105, USA n = 74), all adequately sampled (with a minimum of five tumor sections examined) and histopathologically verified as pT2 (after consensus examination by expert pathologists from three continents), was analyzed. Chilean patients had a significantly worse prognosis based on 5-year all-cause mortality (HR: 1.89, 95% CI: 1.27-2.83, p = 0.002) and disease-specific mortality (HR: 2.41, 95% CI: 1.51-3.84, p < 0.001), compared to their South Korean counterparts, even when controlled for age and sex. Comparing the USA to South Korea, the survival differences in all-cause mortality (HR: 1.75, 95% CI: 1.12-2.75, p = 0.015) and disease-specific mortality (HR: 1.94, 95% CI: 1.14-3.31, p = 0.015) were also pronounced. The 3-year disease-specific survival rates in South Korea, the USA, and Chile were 75%, 65%, and 55%, respectively, the 5-year disease-specific survival rates were 60%, 50%, and 50%, respectively, and the overall 5-year survival rates were 55%, 45%, and 35%, respectively. In conclusion, the survival of true T2 GBC in properly classified cases is neither as good nor as bad as previously documented in the literature and shows notable geographic differences even in well-sampled cases with consensus histopathologic criteria. Future studies should focus on other potential reasons including biologic, etiopathogenetic, management-related, populational, or healthcare practice-related factors that may influence the survival differences of T2 GBC in different regions.

Abstract
Background In the World Health Organization (WHO) classification, gallbladder (GB) intraepithelial lesions are grouped as flat or tumoral, according to their morphological features. The purpose of this study was to investigate the relationship between the morphologies and clinical features of GB cancer (GBC) and to examine the feasibility of using morphologic classification as a prognostic factor. Methods From January 2000 to December 2012, the available pathologic slide reviews of 381 patients were analyzed at the Seoul National University Hospital. All pathologic slides were evaluated by two pancreato-biliary tract pathology experts. GBCs were categorized into eight groups (Flat: F1-2, Borderline, Tumoral: Tu1-5), according to the thickness of the mucosal lesion, histologic patterns of the mucosa under microscopy, invasion extent, and patient history of premalignant lesions. According to the morphologic classification, clinical features were compared and survival analysis was performed. Results In three groups, flat lesions comprised 179 (46.9%) cases and borderline and tumoral comprised 97 (25.4%) and 105 (27.5%) cases, respectively. More favorable pathologic and clinical results were found within the tumoral group. The borderline group had an intermediate tendency between flat and intraluminal in clinicopathologic parameters. In the curative resected T2 stage group, the borderline group demonstrated an intermediate trend compared to that of the flat and tumoral groups, but this was statistically insignificant (P=0.08). Conclusions Flat type GBCs show worse prognosis than tumoral GBCs. The morphological classifications between flat and tumoral on the basis of 1 cm and by papillary feature is feasible. Tumor morphology can be used as a reference while deciding the treatment plan, especially in T2 GBC.

Abstract
We aimed to identify clinicopathological differences and factors affecting survival outcomes of stage T2a and T2b gallbladder cancer (GBC) and validate the oncological benefits of regional lymphadenectomy and hepatic resection in these patients. This single-center study enrolled patients who were diagnosed with pathologically confirmed T2 GBC and underwent curative resection between January 1995 and December 2017. Eighty-two patients with T2a and 50 with T2b GBCs were identified, and clinical information was retrospectively collected from medical records and analyzed. Five-year overall survival rates were 96.8% and 80.7% in T2a and T2b groups, respectively (P = .007). Three- and 5-year survival rates among all patients with T2 GBC without and with lymph node metastasis were 97.2% and 94.4% and 81.3% and 81.3%, respectively (P = .029). There was no difference in survival rates between the 2 groups according to whether hepatic resection was performed (P = .320). However, in the T2b group, those who underwent hepatic resection demonstrated a better survival rate than those who did not (P = .029). The T2b group had more multiple recurrence patterns than the T2a group, and the lymph nodes were the most common site in both groups. Multivariate analysis revealed that lymph node metastasis, vascular invasion, and tumor location were significant independent prognostic factors. Hepatic resection was not always necessary in patients with peritoneal-side GBC. Considering clinicopathological features and recurrence patterns, a systematic treatment plan, including radical resection and adjuvant treatment, should be established for hepatic-side GBC.

Abstract
BACKGROUND Management of operable gall bladder cancer (GBC) is closely related to its tumor (T) and nodal (N) status. The magnitude of benefit with adjuvant chemotherapy in completely resected, node negative T2 cancers is not completely defined. MATERIALS AND METHODS Retrospective analysis of patients diagnosed with pathological T2N0 (stage II, 7th edition AJCC) GBCs from January 2011 to June 2016 was evaluated for adverse risk factors, adjuvant treatment received, recurrence-free survival (RFS), and overall survival (OS). Survival analysis was done using Kaplan-Meier and Cox regression tools. RESULTS Of the 88 patients included, 30 received adjuvant chemotherapy while 58 were observed. The OS and RFS in the entire cohort were 82.9% and 62.7%, respectively, at a median follow-up of 44.18 months. The OS and RFS in the chemotherapy group were 85.1% and 76.4% while it was 81.4% and 55.5% in the observation group (p = 0.50). Recurrent disease was seen in 30.7%.The presence of lymphovascular invasion predicted inferior RFS (p = 0.031). CONCLUSIONS Adjuvant chemotherapy may reduce distant failure rates but did not improve OS in completely resected T2N0 GBC patients in this study. LVI predicted inferior RFS in T2N0 patients. An evaluation of adverse prognostic factors would help design personalized treatment strategies for this select cohort of T2N0 GBC.

Abstract
BACKGROUND AND AIMS T2 gallbladder cancer requires lymph node dissection for curative resection, whereas simple cholecystectomy is adequate to treat T1 gallbladder cancer. Hence, this study aimed to develop an accurate scoring system to preoperatively predict pT2 in gallbladder cancer. MATERIAL AND METHODS We retrospectively assessed data from 57 patients with suspected gallbladder cancer who underwent curative resection between September 2003 and May 2017. Six with apparent invasion of adjacent organs on preoperative images were excluded. We evaluated preoperative computed tomography, magnetic resonance and endoscopic ultrasonographic images, blood biochemistry, and the maximum standard uptake value in fluorodeoxyglucose-positron emission tomography images. We analyzed whether correlations between preoperative findings and the depth of tumor invasion could predict pT2. RESULTS The pathological diagnosis was gallbladder cancer in 30 (58.8%) patients, of whom 21 (69.9%) had pT2 or worse. Multivariate analyses selected carcinoembryonic antigen and tumor diameter as independent predictors of pT2 or worse (odds ratios = 1.741 and 1.098, respectively; 95% confidence intervals = 1.004-3.020 and 1.008-1.197, respectively). A regression formula was created using carcinoembryonic antigen and tumor diameter to calculate pT2 predictive scores. The area under the receiver operating characteristics curve of the pT2 predictive score was 0.873. CONCLUSION We created a scoring system to predict pT2 in gallbladder cancer using carcinoembryonic antigen and tumor diameter. The present findings suggested that carcinoembryonic antigen is important for the preoperative evaluation of gallbladder cancer.

Abstract
At MSKCC, over 50% of the patients presenting with gallbladder cancer have been diagnosed incidentally following elective cholecystectomy for presumed benign disease. While traditional management of incidental gallbladder cancer (IGBC) dictates re-resection with the ultimate goal of achieving cure, surgical decision-making must take into account that this malignancy is characterized by poor tumor biology with frequent distant recurrence. Since early and frequent distant recurrence is the most common cause of surgical failure, the surgical oncologist's goal should be to selectively re-resect only those patients most likely to benefit from an operation. The astute surgeon recognizes the high-risk patients who likely have micrometastatic disease at the time of diagnosis and alters the treatment sequence, delivering neoadjuvant chemotherapy. This strategy acts as a selection tool, as those progressing at distant sites during therapy are spared the morbidity and mortality of surgery and furthermore has the potential to treat micrometastatic disease. However, a chemotherapy first approach must be applied selectively since a poor response risks local progression to unresectability and a decrease in functional status that comes from the toxicities of dual agent chemotherapy that can impair surgical candidacy. To balance these risks and benefits, two other criteria for a neoadjuvant approach must be met: i) reliable identification of those patients who are at high risk of distant recurrence and who are, therefore, most likely to benefit from a systemic therapy first approach and ii) availability of effective chemotherapy options. In this review, we will outline the data and judgement we use to select a treatment sequence at our institution.

Abstract
Background Whether the extra-hepatic bile duct (EHBD) should be routinely resected for gallbladder carcinoma (GBC) remains controversial. The current study aimed to determine the clinical impact of combined EHBD resection during curative surgery for advanced GBC. Methods In total, 213 patients who underwent curative surgery for T2, T3 or T4 GBC were enrolled. The clinicopathological features were compared between the patients treated with EHBD resection and those without EHBD resection. Meanwhile, univariable and multivariable Cox-proportional hazards regression models were used to identify risk factors for overall survival (OS). Results Among the 213 patients identified, 87 (40.8%) underwent combined EHBD resection. Compared with patients without EHBD resection, patients with EHBD resection suffered more post-operative complications (33.3% vs. 21.4%, P = 0.046). However, the median OS of the EHBD resection group was longer than that of the non-EHBD resection group (25 vs. 11 months, P = 0.008). Subgroup analyses were also performed according to tumor (T) category and lymph-node metastasis. The median OS was significantly longer in the EHBD resection group than in the non-EHBD resection group for patients with T3 lesion (15 vs. 7 months, P = 0.002), T4 lesion (11 vs. 6 months, P = 0.021) or lymph-node metastasis (12 vs. 7 months, P < 0.001). No survival benefit of EHBD resection was observed in GBC patients with T2 lesion or without lymph-node metastasis. T category, lymph-node metastasis, margin status, pre-operative CA19-9 level and EHBD resection were identified as independent prognostic factors for OS of patients with advanced GBC (all P values <0.05). Conclusions EHBD resection can independently affect the OS in advanced GBC. For GBC patients with T3 lesion, T4 lesion and lymph-node metastasis, combined EHBD resection is justified and may improve OS.

Validation of the oncologic effect of hepatic resection for T2 gallbladder cancer: a retrospective study. World J Surg Oncol 2019; 17:8. [PMID: 30616645 PMCID: PMC6323785 DOI: 10.1186/s12957-018-1556-6] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Accepted: 12/27/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND While extended cholecystectomy is recommended for T2 gallbladder cancer (GBC), the role of hepatic resection for T2 GBC is unclear. This study aimed to identify the necessity of hepatic resection in patients with T2 GBC. METHODS Data of 81 patients with histopathologically proven T2 GBC who underwent surgical resection between January 1999 and December 2017 were enrolled from a retrospective database. Of these, 36 patients had peritoneal-side (T2a) tumors and 45 had hepatic-side (T2b) tumors. To identify the optimal surgical management method, T2 GBC patients were classified into the hepatic resection group (n = 44, T2a/T2b = 20/24) and non-hepatic resection group (n = 37, T2a/T2b = 16/21). The recurrence pattern and role of hepatic resection for T2 GBC were then investigated. RESULTS Mean age of the patients was 69 (range 36-88) years, and the male-to-female ratio was 42:39 (male, 51.9%; female, 48.1%). Hepatic-side GBC had a higher rate of recurrence than peritoneal-side GBC (44.4% vs. 8.3%, p = 0.006). The most common type of recurrence in T2a GBC was para-aortic lymph node recurrence (n = 2, 5.6%); the most common types of recurrence in T2b GBC were para-aortic lymph node recurrence (n = 7, 15.6%) and intrahepatic metastasis (n = 6, 13.3%). Hepatic-side GBC patients had worse survival outcomes than peritoneal-side GBC patients (76.0% vs. 96.6%, p = 0.041). Hepatic resection had no significant treatment effect in T2 GBC patients (p = 0.272). Multivariate analysis showed that lymph node metastasis was the only significant prognostic factor (p = 0.002). CONCLUSIONS Hepatic resection is not essential for curative treatment in T2 GBC, and more systemic treatments are needed for GBC patients, particularly for those with T2b GBC.

Abstract
Radical resection with or without preserving extra-hepatic bile duct has shown similar prognoses for gallbladder carcinoma. In the case of ischemic biliary complications of gallbladder carcinoma, whether to preserve the extrahepatic bile duct is a critical issue. Authentic indocyanine green near-infrared imaging is feasible for the estimation of the correct blood flow in postoperative ischemic biliary complications.
Introduction Radical resection with or without preserving extra-hepatic bile duct has shown similar prognoses for gallbladder carcinoma (GB ca), although aggressive resection is essential. In preserving bile duct, ischemic complications are serious, life-threatening serious problems. Correct evaluation of the blood flow to the biliary tract is crucial. Case presentation A case of gallbladder ca in a 62-year-old man was reported. The patient was diagnosed with stage Ⅱ GB ca (T2, N0, M0) by ultrasonography, computed tomography, magnetic resonance imaging, and endoscopic ultrasonography. Cholecystectomy and intraoperative frozen section examination were planned. After recognition of invasion to subserosa and negative cystic duct margin, radical dissection of the lymph nodes in the hepatoduodenal ligament with preserving biliary tract was performed. Three days after the operation, biliary peritonitis was revealed. Emergency laparotomy showed ischemic bile leakage. Proper blood flow of the biliary system was realized by a near-infrared ray vision system (Photo Dynamic Eye®: HAMAMATSU Photonics) using indocyanine green. Primary suture of the extra-hepatic biliary duct and T-tube drainage were selected. No stricture of the bile system nor recurrence was recognized for two years after surgery. Discussion In the case of ischemic biliary complications, whether to preserve the extrahepatic bile duct is a critical issue for the surgeons. In this case study, the feasibility of authentic indocyanine green near-infrared imaging was shown for postoperative ischemic biliary situations. Conclusions Authentic indocyanine green near-infrared imaging was feasible for the estimation of the blood flow to the postoperative ischemic biliary complication.

Abstract
Purpose The clinical behavior of T2 gallbladder cancer varies among patients. The aims of this study were to identify prognostic factors for survival and recurrence, and to determine the optimal surgical strategy for T2 gallbladder cancer. Methods We conducted a retrospective analysis of 78 patients with T2 gallbladder cancer who underwent surgical resection for gallbladder cancer. Results Twenty-eight patients (35.9%) underwent simple cholecystectomy and 50 (64.1%) underwent extended cholecystectomy. Among 56 patients without LN metastasis (n = 20) or unknown LN status (no LN dissection, n = 36), the 5-year disease-free survival rates were 81.6%, and 69.8% (P = 0.080). In an analysis according to tumor location, patients with tumors located on the hepatic side (n = 36) had a higher recurrence rate than patients with tumors located on the peritoneal side only (n = 35) (P = 0.043). On multivariate analysis, R1 resection and lymph node metastasis were significant, independent prognostic factors for poor disease-free and overall survival. Conclusion R0 resection and LN dissection are an appropriate curative surgical strategy in patients with T2 gallbladder cancer. Tumors located on the hepatic side show worse prognosis than tumors located on the peritoneal side only, hepatic resection should be considered.

Abstract
This study was conducted to investigate the expressions of DDR2 and IFITM1 and their clinical and pathological significances in the rare type squamous cell/adenosquamous carcinomas (SC/ASC) and ordinary adenocarcinomas (AC) of gallbladder cancers. DDR2 and IFITM1 expression was examined in 69 SC/ASCs and 146 ACs using EnVision immunohistochemistry. Results showed that the percentage of positive DDR2 and IFITM1 expression was significantly higher in SC/ASC patients with high TNM stage, lymph node metastasis, invasion, and no resection surgery compared to patients with low TNM stages, no lymph node metastasis, no invasion, and resection surgery (P < 0.05 or P < 0.01). The positive rate of DDR2 was significantly higher in SC/ASC patients with large tumor sizes than patients with small tumor sizes (p < 0.05). The percentage of positive DDR2 and IFITM1 expressions was significantly higher in AC patients with high TNM stages that didn't receive resection surgery compared to patients with low TNM stages that did receive resection surgery (P < 0.05 or P < 0.01). The positive rate of IFITM1 was significantly higher in AC patients with lymph node metastasis and invasion than in patients without metastasis and invasion (p < 0.05). Positive DDR2 and IFITM1 expression was closely associated with a decreased overall survival in SC/ASC and AC patients (P < 0.05 or P < 0.01). AUC analysis showed that DDR2 and IFITM1 was sensitive and specific for the diagnosis of SC/ASC (AUC = 0.740 and AUC =0.733, respectively) and AC (AUC = 0.710 and AUC =0.741, respectively). In conclusion, positive DDR2 and IFITM1 expression is a marker for the clinical severity, poor prognosis, and diagnosis of gallbladder SC/ASC and AC.

Abstract
OBJECTIVE To assess if simple cholecystectomy with adjuvant therapy could provide outcomes comparable to extended cholecystectomy. BACKGROUND Current guidelines recommend extended/radical cholecystectomy for T2/T3 gallbladder cancer; however, many tumors are discovered incidentally at laparoscopic cholecystectomy. METHODS The national Cancer Data Base 2004 to 2014 was queried for patients with pT2/T3 gallbladder adenocarcinoma who underwent resection. Adjuvant therapy was defined as chemotherapy, with or without radiotherapy, within 90 days of surgery. Baseline characteristics and overall survival were compared by χ and Kaplan-Meier method, respectively. One-to-one propensity score matching for receipt of adjuvant therapy was used to account for potential selection bias. RESULTS A total of 6825 patients were identified. Diagnosis was made predominantly (78.9%) at the time of surgery or on pathology; 31.8% (2168) received adjuvant therapy. The majority, 88.8% (6060), had a simple cholecystectomy. Patients who received adjuvant therapy versus surgery alone were more likely to: be younger, privately insured, have no comorbidities, pT3 disease, positive lymph nodes, positive resection margins, and extended cholecystectomy. After matching, median survival was significantly longer for extended cholecystectomy with adjuvant therapy (23.3 months) than cholecystectomy with adjuvant therapy (16.4 months), which was significantly longer than either simple (12.4 months) or extended (10.7 months) cholecystectomy alone (all log-rank P<0.001). CONCLUSIONS Adjuvant therapy prolongs survival after resection of T2/T3 tumors. Simple cholecystectomy with adjuvant therapy appears to be superior to extended resection alone in the short term and may serve as a potential alternative to re-resection in select high-risk individuals.

Abstract
AIM To evaluate a laparoscopic approach to gallbladder lesions including polyps, wall-thickening lesions, and suspected T1 and T2 gallbladder cancer (GBC).
METHODS We performed 50 cases of laparoscopic whole-layer cholecystectomy (LCWL) and 13 cases of laparoscopic gallbladder bed resection (LCGB) for those gallbladder lesions from April 2010 to November 2016. We analyzed the short-term and long-term results of our laparoscopic approach.
RESULTS The median operation time was 108 min for LCWL and 211 min for LCGB. The median blood loss was minimal for LCWL and 28 ml for LCGB. No severe morbidity occurred in either procedure. Nine patients who underwent LCWL and 7 who underwent LCGB were postoperatively diagnosed with GBC. One of these patients had undergone LCGB for pathologically diagnosed T2 GBC after LCWL. All of the final surgical margins were negative. Three of these 15 patients underwent additional open surgery. The mean follow-up period was 26 mo, and only one patient developed recurrence.
CONCLUSION LCWL and LCGB are safe and useful procedures that allow complete resection of highly suspected or early-stage cancer and achieve good short-term and long-term results.

Abstract
Treatment of gall bladder cancer (GBC) has traditionally been viewed with pessimism and lymph node positivity has been associated with worse prognosis. The aim of this study is to analyze the role of radical cholecystectomy in T2 tumors. All patients who underwent surgery for GBC between September 2005 and June 2014 were identified retrospectively. Data collected included clinical presentation, operative findings, and histopathological data. Twenty-five patients had incidental GBC diagnosis after cholecystectomy. Ten patients were T2 on initial cholecystectomy pathology and all underwent radical resection. Two patients were N1 on initial cholecystectomy pathology. Four were upstaged to N1 and two patients were upstaged to T3 after further surgery. Overall, 60 per cent patients with T2 disease had node positivity and 60 per cent were upstaged by further surgery. Eleven patients were diagnosed on imaging. Four of these patients were unresectable and six were either stage T3 or higher or node positive. Sixty per cent of T2 GBC was node positive and 60 per cent were upstaged with radical cholecystectomy. This finding supports the call for radical resection in patients with incidental diagnosis of T2 tumor on cholecystectomy. This study also emphasizes the role of radical surgery in accurate T staging.

Abstract
Gallbladder cancer is the most common tumor of the biliary tract and it is associated with a poor prognosis. Unexpected gallbladder cancer is a cancer incidentally discovered, as a surprise, at the histological examination after cholecystectomy for gallstones or other indications. It is a potentially curable disease, with an intermediate or good prognosis in most cases. An adequate surgical strategy is mandatory to improve the prognosis and an adjunctive radical resection may be required depending on the depth of invasion. If the cancer discovered after cholecystectomy is a pTis or a pT1a, a second surgical procedure is not mandatory. In the other cases (pT1b, pT2 and pT3 cancer) a re-resection (4b + 5 liver segmentectomy, lymphadenectomy and port-sites excision in some cases) is required to obtain a radical excision of the tumor and an accurate disease staging. The operative specimens of re-resection should be examined by the pathologist to find any “residual” tumor. The “residual disease” is the most important prognostic factor, significantly reducing median disease-free survival and disease-specific survival. The other factors include depth of parietal invasion, metastatic nodal disease, surgical margin status, cholecystectomy for acute cholecystitis, histological differentiation, lymphatic, vascular and peri-neural invasion and overall TNM-stage.

Abstract
BACKGROUND While survival after malignancies is traditionally reported as actuarial survival, conditional survival (CS) may be more clinically relevant by accounting for "accrued" survival time as time progresses. We sought to compare actuarial and CS among patients with gallbladder carcinoma (GBC) . METHODS A total of 312 patients who underwent curative intent surgery for GBC between 2000 and 2014 were identified using a multi-institutional database. Overall survival (OS) was estimated using the Kaplan-Meier method. CS was calculated as the probability of surviving an additional 3 years at year "x" after surgery using the formula CS3 = S(x+3)/Sx. RESULTS Among all patients, the median actuarial OS was 24.8 months (IQR 13.3-88.9). While actuarial survival decreased over time, 3-year CS (CS3) increased, with CS3 at 2 years after surgery noted to be 61.8 % compared with the 5-year actuarial OS of 31.6 %. Factors associated with reduced actuarial OS were positive margin status (HR 3.61, 95 % CI 2.47-5.26), increasing tumor size (HR = 1.02, 95 % CI 1.01-1.02), higher tumor grade (HR 2.98, 95 % CI 1.47-6.04), residual disease at repeat resection (HR = 2.78, 95 % CI 1.49-3.49, p < 0.001), and lymph node metastasis (HR = 1.95, 95 % CI 1.39-2.75, all p < 0.001). The calculated CS3 exceeded the actuarial survival within each high-risk patient subgroup. For example, patients with residual disease at repeat resection had an actuarial survival 23.1 % at 5 years versus a CS3 of 56.3 % in patients alive at 2 years (Δ = 33.2 %). CONCLUSIONS CS provides a more accurate, dynamic estimate for survival, especially among high-risk patients. CS estimates can be used to accurately predict survival and guide clinical decision making.

Abstract
BACKGROUND Prophylactic combined extrahepatic bile duct resection remains controversial for locally advanced gallbladder carcinoma without extrahepatic bile duct invasion. The aim of this study is to resolve this issue and establish an appropriate surgery for locally advanced gallbladder carcinoma. METHODS A total of 52 patients underwent surgical resection combined with extrahepatic bile duct resection for locally advanced gallbladder carcinoma without extrahepatic bile duct invasion, and their medical records were retrospectively reviewed for microvessel invasion (MVI), including lymphatic, venous, and/or perineural invasions, around the extrahepatic bile duct. RESULTS Of the 52 patients, 8 (15 %) had MVI around the extrahepatic bile duct. All of the 8 patients had Stage IV disease. According to a survival analysis of the 50 patients who tolerated surgery, MVIs around the extrahepatic bile duct and distant metastasis were identified as independent prognostic factors. Survival for patients with MVI around the extrahepatic bile duct was dismal, with a lack of 2-year survivors. CONCLUSIONS MVI around the extrahepatic bile duct is a sign of extremely locally advanced gallbladder carcinoma; therefore, prophylactic combined bile duct resection has no survival impact for patients without extrahepatic bile duct invasion.

Abstract
BACKGROUND/AIMS Extended cholecystectomy is generally recommended for patients with T2 gallbladder cancer. However, few studies have assessed the extent of resection relative to T2 gallbladder tumor location. This study analyzed the effects of surgical methods and tumor location on survival outcomes and tumor recurrence in patients with T2 gallbladder cancer. METHODS Clinicopathological characteristics, extent of resection, survival rates, and recurrence patterns were retrospectively analyzed in 88 patients with pathologically confirmed T2 gallbladder cancer. RESULTS The 5-year disease-free survival rate was 65.0%. Multivariate analysis showed that lymph node metastasis was the only independent risk factor for poor 5-year disease-free survival rate. Survival outcomes were not associated with tumor location. Survival tended to be better in patients who underwent extended cholecystectomy than in those who underwent simple cholecystectomy. Recurrence rate was not affected by surgical method or tumor location. Systemic recurrence was more frequent than local recurrence without distant recurrence. Gallbladder bed recurrence and liver recurrence were relatively rare, occurring only in patients with liver side tumors. CONCLUSIONS Extended cholecystectomy is the most appropriate treatment for T2 gallbladder cancer. However, simple cholecystectomy with regional lymph node dissection may be appropriate for patients with serosal side tumors.

Abstract
Gallbladder carcinoma is a relatively uncommon cancer of gastrointestinal (GI) tract. Medical literature is full of nihilistic reports about the treatment of gallbladder carcinoma, especially due to its resistance to current radiotherapeutic or chemotherapeutic treatment modalities and difficult surgical approach for complete resection of these tumors. Herein, we review current diagnostic and therapeutic approaches to this rare GI cancer.

Abstract
BACKGROUND Laparoscopic treatment for gallbladder cancer (GBC) has long been contraindicated, but few studies have demonstrated the oncologic outcomes of this treatment. The purpose of this study was to evaluate long-term survival after intended laparoscopic surgery for early-stage GBC based on our 10 years of experience. STUDY DESIGN Between May 2004 and April 2014, eighty-three patients suspected of having early-stage GBC with no evidence of liver invasion were enrolled in the prospective protocol for laparoscopic surgery. Data for 45 of these patients with pathologically proven GBC were analyzed to determine the safety and oncologic outcomes of a laparoscopic approach to GBC. Twenty-six patients whose postoperative follow-up exceeded 5 years were investigated to determine the 5-year actual survival outcomes. RESULTS Extended cholecystectomy, including laparoscopic lymphadenectomy, was performed in 32 patients and simple cholecystectomy in 13 patients. The T stages based on final pathologic results were Tis (n = 2), T1a (n = 10), T1b (n = 8), and T2 (n = 25). After a median follow-up of 60 months after surgery, recurrence was detected in 4 patients as distant metastases. There was no local recurrence around the gallbladder bed or lymphadenectomy. Disease-specific 5-year survival rate of the 45 patients was 94.2%. Disease-specific actual survival rate of 26 patients whose postoperative follow-up period exceeded 5 years was 92.3% at 5 years. CONCLUSIONS The favorable long-term oncologic results shown in this study confirm the oncologic safety of laparoscopic cholecystectomy, including laparoscopic lymphadenectomy in selected patients with GBC.

Abstract
Background/Aim. To assess whether the diagnostic power of longitudinal multiplanar reformat (MPR) images is superior to that of conventional horizontal images for gallbladder cancer (GBC). Methods. Between 2006 and 2010, a total of 54 consecutive patients with preoperatively diagnosed gallbladder neoplasms located in gallbladder bed were analyzed. These patients underwent cholecystectomy with resection of the adjacent liver parenchyma. The patients were divided into the GBC group (n = 30) and the benign group (n = 24). MPR images obtained by preoperative multidetector row CT (MDCT) were assessed. Results. Mucosal line was more significantly disrupted in GBC group than that in benign group (93% [28/30 patients] versus 13% [3/24], p < 0.001). Maximum (9.3 [4.2-24.8] versus 7.0 mm [2.4-22.6], p = 0.29) and minimum (1.2 [1.0-2.4] versus 1.3 mm [1.0-2.6], p = 0.23) wall thicknesses on a single MPR plane did not differ significantly; however, the wall thickness ratio (max/min) differed significantly (6.8 [1.92-14.0] versus 5.83 [2.3-8.69], p = 0.04). Partial liver enhancement adjacent to tumor on longitudinal images was more common in GBC (40.0% [12/30 patients] versus 12.5% [3/24], p = 0.03). Mucosal line disruption was the most reliable independent predictor of diagnosis (odds ratio, 8.5; 95% CI, 5.99-28.1, p < 0.001). Conclusion. Longitudinal MPR images are more useful than horizontal images for the diagnosis of GBC.

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
BACKGROUND The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract and ampullary carcinomas in 2008. Novel treatment modalities and handling of clinical issues have been proposed after the publication. New approaches for editing clinical guidelines, such as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, also have been introduced for better and clearer grading of recommendations. METHODS Clinical questions (CQs) were proposed in seven topics. Recommendation, grade of recommendation and statement for each CQ were discussed and finalized by evidence-based approach. Recommendation was graded to grade 1 (strong) and 2 (weak) according to the concept of GRADE system. RESULTS The 29 CQs covered seven topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, (6) radiation therapy, and (7) pathology. In 27 CQs, 19 recommendations were rated strong and 11 recommendations weak. Each CQ included the statement of how the recommendation was graded. CONCLUSIONS This guideline provides recommendation for important clinical aspects based on evidence. Future collaboration with cancer registry will be a key for assessment of the guidelines and establishment of new evidence.

Abstract
BACKGROUND A small proportion of gallbladder carcinomas (GBC) are incidentally detected after laparoscopic cholecystectomy (LC). This study intended to analyze the effect of extended reoperation on the long-term outcome of patients with pT1b/T2 GBC who had initially undergone LC. METHODS A cohort of 203 patients who underwent R0 resection and whose pathology was pT1b or pT2 GBC was divided into 3 groups: open surgery (group I, n = 150), LC only (group II, n = 25), and initial LC and subsequent reoperation (group III, n = 28). RESULTS Mean ages were 62.3 ± 9.6 years, 65.9 ± 11.8 years, and 57.1 ± 7.7 years in groups I, II, and III, respectively (p = 0.001). The numbers of pT1b and pT2 patients were 75 and 75 in group I, 15 and 10 in group II, and 6 and 22 in group III, respectively. Residual tumors after LC were found in none of 6 pT1b patients and 5 of 22 pT2 patients. Overall 5-year patient survival rate was 70.1 % for all-cause death and 73.5 % for tumor recurrence-associated death (76.0 % in group I, 64.0 % in group II, and 63.0 % in group III [p = 0.607]; 84.4 % in pT1b group I, 68.8 % in pT1b group II, and 83.3 % in pT1b group III [p = 0.649]; 67.6 % in pT2 group I, 50 % in pT2 group II, and 61.9 % in pT2 group III [p = 0.895]). Concurrent bile duct resection in pT2 patients did not affect survival outcomes (p = 0.601). CONCLUSIONS No definite survival benefit from reoperation was observed in patients with pT1b lesions. Residual tumor was found in 23 % of pT2 patients after reoperation, and the survival outcomes of these patients were comparable to those of the open surgery group. Therefore, reoperation for pT1b GBC following LC can be individually indicated because its indication remains unclear, but it should be highly recommended for pT2 GBC.

Abstract
BACKGROUNDS/AIMS Gallbladder carcinoma is usually associated with an unfavorable prognosis, and the clinical outcome has not improved much. This study was conducted to evaluate outcomes with gallbladder carcinoma according to the type of surgery performed, and the prognostic factors for survival. METHODS One hundred and six patients with gallbladder carcinoma, who underwent surgery for the purpose of curative resection between January 1999 and June 2012 were reviewed retrospectively. RESULTS Out of 106 patients, curative resection was achieved in 75 (70.8%). The cumulative 1-, 2- and 5-year survival rates of the gallbladder carcinoma patients were 93.4%, 80.9% and 63.0%, respectively. Radical resections, including extended cholecystectomy, were more beneficial for long term survival of patients. The 5-year survival rate in patients who underwent curative resection (56.9%) was significantly higher than in those who underwent palliative resection (0%, p=0.000). Multivariate analysis revealed that curative resection, preoperative CA19-9, T-stage, N-stage and differentiation of histology were independently significant prognostic factors. CONCLUSIONS Curative resection and early detection of patients with gallbladder carcinoma were the most important factors for long term survival. Radical resection improves survival for patients with localized gallbladder carcinoma and can help to access exact prognosis and treatments.

Abstract
BACKGROUND Laparoscopic surgery has been widely employed in the field of digestive surgery, since the minimally invasive procedure provides a significant benefit to patients. However, laparoscopic curative surgery for gallbladder cancer has been rarely described. The aim of this study was to evaluate the effectiveness and validity of laparoscopic radical cholecystectomy with lymph node dissection (Lap-RC) to treat with T1b/T2 gallbladder carcinoma. METHODS A total of 11 patients underwent Lap-RC for gallbladder carcinoma from November 2001 until June 2013. While 4 patients were preoperatively diagnosed with T1b/T2 gallbladder carcinoma, 7 patients were diagnosed with incidental T1b/T2 gallbladder carcinoma by postoperative pathological examination after laparoscopic cholecystectomy. Common bile duct resection and biliary tract reconstruction were performed in 2 cases. End points in this clinical study were tumor recurrence and survival of patients. RESULTS Mean operative time was 196 min, and average hospital stay after surgery was 6.4 days, excluding 2 cases with biliary tract reconstruction. One patient died of recurrence of cancer 89 months after surgery, and another patient died of other reason with local recurrence 39 months after the operation. The other 9 patients were all alive without recurrence at this writing. The 5-year survival rate was 100 % for T1b patients and 83.3 % for T2. These results indicate that almost equivalent outcomes compared with open surgery in terms of curability were achieved. CONCLUSIONS We conclude that pure laparoscopic radical cholecystectomy with lymph node dissection is safe and beneficial for the patients with T1b/T2 gallbladder carcinoma.

Abstract
At present, surgical treatment is the only curative option for gallbladder (GB) cancer. Many efforts therefore have been made to improve resectability and the survival rate. However, GB cancer has a low incidence, and no randomized, controlled trials have been conducted to establish the optimal treatment modalities. The present guidelines include recent recommendations based on current understanding and highlight controversial issues that require further research. For T1a GB cancer, the optimal treatment modality is simple cholecystectomy, which can be carried out as either a laparotomy or a laparoscopic surgery. For T1b GB cancer, either simple or an extended cholecystectomy is appropriate. An extended cholecystectomy is generally recommended for patients with GB cancer at stage T2 or above. In extended cholecystectomy, a wedge resection of the GB bed or a segmentectomy IVb/V can be performed and the optimal extent of lymph node dissection should include the cystic duct lymph node, the common bile duct lymph node, the lymph nodes around the hepatoduodenal ligament (the hepatic artery and portal vein lymph nodes), and the posterior superior pancreaticoduodenal lymph node. Depending on patient status and disease severity, surgeons may decide to perform palliative surgeries.

Abstract
INTRODUCTION Even now, cystic duct cancer (CDC) as defined by Farrar is rare and has a better prognosis than gallbladder cancer, although CDC as defined by Ozden et al., the definition of which could apply to early and advanced cases of CDC, is not rare and has a poorer prognosis than the CDC defined by Farrar. PRESENTATION OF CASE A 78-year-old woman with no complaints was found to have a tumor restricted to the cystic duct. Three cytology examinations of the patient's bile could not establish that the tumor was an adenocarcinoma. However, adenocarcinoma was suspected due to the hypervascularity shown on contrast-enhanced computed tomography. Cholecystectomy and extrahepatic bile duct resection with D2 lymph node dissection was performed. The pathological study revealed it to be CDC. Her postoperative course has been uneventful and without recurrence for 21 months. DISCUSSION At their first medical examination, many CDC patients are found to have such advanced spread of the cancer to adjacent organs that an extended operation might be necessary. As in our case, better patient outcome results when no lymph node or remote metastasis is present. CONCLUSION Diagnosing CDC as early as possible contributes to curative resections and favorable patient outcomes and also allows surgeons to recommend a mini-invasive procedure to their patients rather than extended resection including that of adjacent organs.

Abstract
PURPOSE Hepatectomy of segments 4a and 5 (S4a+5) is the recommended treatment for pT2 gallbladder cancer. However, gallbladder bed resection is also occasionally used. Using nationwide data from the Japanese Biliary Tract Cancer Registry and a questionnaire survey, we retrospectively compared these 2 methods of treatment. METHOD The study involved 85 patients with pT2, pN0 gallbladder cancer (55 treated with gallbladder bed resection, and 30, with S4a+5 hepatectomy). The prognosis and mode of tumor recurrence following treatment were analyzed retrospectively, with overall survival as the endpoint. RESULTS The 5-year survival rate did not differ significantly between the 2 groups. Univariate analysis showed that bile duct resection and perineural tumor invasion were significant prognostic factors, but the extent of hepatectomy, location of the major intramural tumor, regional lymph node excision, and histological type were not. Multivariate analysis identified perineural tumor invasion as a significant prognostic factor. Recurrence occurred most frequently in both lobes than S4a+5 of the liver following gallbladder bed resection. CONCLUSION In the present study of cases of Japanese Biliary Tract Cancer Registry, it was not possible to conclude that S4a+5 hepatectomy was superior to gallbladder bed resection.

Abstract
PURPOSE To evaluate the performance of biliary MRI, including unenhanced imaging, gadolinium-enhanced (Gd-E) dynamic imaging, and MR cholangiography, for the preoperative staging of gallbladder cancer (GBC). MATERIALS AND METHODS Our institutional review board approved this retrospective study. Eighty-six, consecutive patients with surgically resected and pathologically confirmed GBCs and who underwent preoperative MRI, including unenhanced T1- and T2-weighted images, MR cholangiography, and dynamic imaging, were enrolled in this study. Two observers independently evaluated the biliary MR images regarding the T- and N-staging of GBCs and graded their diagnostic confidence for the staging using a 5-point scale. Receiver operating curve analysis was performed to evaluate the diagnostic performance of MR in the staging of GBC. Interobserver agreement was evaluated using kappa statistics. RESULTS The overall accuracy of T- and N-staging using biliary MRI was 84.9% and 77.9% for observer 1 and 69.8% and 74.4% for observer 2. There was good interobserver agreement regarding the T stage (k = 0.828). The Az (AUC: area under the curve) values of the diagnostic ability of MRI to differentiate ≥ T1b from ≤ T1a lesions, were 0.979 and 0.955 for both observers (P < 0.0001). CONCLUSION Biliary MRI with MR cholangiography allows moderately accurate preoperative T staging and N staging of GBCs. It also shows an excellent diagnostic ability for differentiating ≥ T1b lesions from ≤ T1a lesions, which can be helpful for preoperative planning.

Abstract
AIMS To assess the accuracy of pathology reports on gallbladder specimens from patients operated on for incidental gallbladder carcinoma. METHODS Demographic data, details on pathological reports including gross and microscopic features section were recorded in 100 selected patients with incidental gallbladder carcinoma diagnosed from 2004 to 2007. RESULTS Pathology reports had a conventional format in 93% of cases, without any standardization. Turnaround time ranged from 1 to 35 days. Frozen sections were performed in 20% of cases. The reports failed to give information on prognostic histological factors: exact tumour site (missing in 55% of cases), depth of tumour infiltration within the gallbladder wall (missing in 10%), surgical margins (missing in 40% for the cystic duct margin), tumour differentiation (missing in 28%), vascular invasion (missing in 52%) and perineural invasion (missing in 51%). Lymph node status could be assessed in 44% of cases. Distances between the tumour and the cystic duct and circumferential margins were not specified in 68% and 84% of cases. Only 29% of the reports clearly stated the pTNM stage in the conclusion section. The pT stage with margin status and tumour site was only mentioned in 30% of the reports. CONCLUSION Pathology reports on gallbladder carcinoma from participating centres frequently lacked important information on key prognostic histological factors.

Abstract
OBJECTIVE To evaluate the diagnostic performance of gadoxetic acid-enhanced MRI with an emphasis on the usefulness of the hepatobiliary phase (HBP) in T-staging of gallbladder carcinoma. METHODS 66 patients with surgically confirmed gallbladder carcinoma underwent MRI. Two radiologists independently reviewed two sets of gadoxetic acid-enhanced MRI without and with the HBP. Local tumour spread was evaluated according to T-staging, and the results were compared with pathological findings. The diagnostic performance of two image sets to differentiate each T-stage was compared. RESULTS The sensitivities of MRI with the HBP to differentiate T1 vs ≥ T2 lesions, ≤ T2 vs ≥ T3 lesions and ≤ T3 vs T4 lesions were 96.3%, 85.7% and 100% for Observer 1 and 92.6%, 95.2% and 100% for Observer 2, respectively (p<0.0001). By adding the HBP, the sensitivities to differentiate ≤ T2 vs ≥ T3 lesions were increased from 66.7% to 85.7% for Observer 1 and from 81.0% to 95.2% for Observer 2, although there was no significant difference (p>0.05). The overall accuracies for T-staging were increased from 80.3% to 86.4% for Observer 1, a statistically significant degree (p=0.046), and from 83.8% to 87.9% for Observer 2 (p>0.05). The k-value for the two observers indicated excellent agreement. CONCLUSION Gadoxetic acid-enhanced MRI provided acceptable diagnostic performance for T-staging of gallbladder carcinoma. Addition of the HBP aids in the detection of liver invasion. ADVANCES IN KNOWLEDGE In the T-staging of gallbladder carcinoma, gadoxetic acid-enhanced MRI with the HBP may enhance detection of liver invasion.

Abstract
PURPOSE Resection of the extrahepatic bile duct is not performed uniformly in gallbladder cancer. The study investigated the clinical significance of resection of extrahepatic bile duct (EHBD) in T2 and T3 gallbladder cancer. METHODS Between 2000 and 2010, 71 T2 or T3 gallbladder cancer patients who underwent R0 resection at Korea University Medical Center were included. Clinicopathological data were reviewed retrospectively. Survival analysis and comparison between EHBD resection and non-resection groups were performed. RESULTS The 32 men and 39 women had 49 T2 tumors and 22 T3 tumors. The overall survival rate was 67.8 % at 3 years and 47.2 % at 5 years. In multivariate analysis for overall survival, lymphovascular invasion and lymph node metastasis were significant independent predictors. Comparing the patients according to EHBD resection, the EHBD resection group demonstrated significantly longer hospital stay, longer operative time, more transfusion requirement, more extensive liver resection, and less treatment of neoadjuvant therapy. Significantly higher proportions of perineural invasion and lymph node metastasis were noted in the EHBD resection group. There were no statistically significant differences in survival between the EHBD resection and non-resection groups. CONCLUSIONS Resection of extrahepatic bile duct was not always necessary in T2 and T3 cancers. However, the patients who undergo resection of extrahepatic bile duct tended to have more aggressive tumor characteristics and undergo more aggressive surgical approach. To enhance overall survival for the patients with T2 and T3 gallbladder cancers, surgeons should try to perform R0 resection including EHBD resection.

Abstract
BACKGROUNDS/AIMS Laparoscopic cholecystectomy (LC) has become a standard procedure for treatment of benign gallbladder diseases. There has been a small proportion of gallbladder cancer (GBC) which was incidentally found in the gallbladder specimen, and LC has been tried in some patients with faintly suspected GBC. This study intended to analyze the prognosis of patients with pT1b/T2 GBC who have undergone LC and the outcome of extended re-operation. METHODS After analyzing the institutional profiles of 500 GBC patients who have undergone surgical resection, we selected 64 patients who underwent LC initially from January 1996 to December 2008 and whose gallbladder pathology was confined to pT1b or pT2 lesions. Of them, 34 patients (53.1%) underwent extended reoperation. Their medical records were reviewed retrospectively. RESULTS In the LC only group (n=30), mean age of the 16 pT1 patients was 65.7±12.5 years and mean age of the 14 pT2 patients was 66.7±10.1 years. In the reoperation group (n=34), mean age of the 8 pT1b patients was 52.6±9.9 years and in 26 pT2 patients, mean age was 59.2±7.9 years. The reoperation group showed a younger patient age pattern than the LC only group (p=0.001). The types of reoperation were liver resection with lymph node (LN) dissection in 17, bile duct resection with LN dissection in 2, and hepatectomy and bile duct resection with LN dissection in 15. In the LC only group, the 5-year survival rate (5-YSR) was 70.3% in pT1b and 43.2% in pT2. In the reoperation group, 5-YSR was 62.5% in pT1b (n=8) and 59.5% in pT2 (n=26). A survival comparison between the two groups showed no significant survival gain in pT1 patients (p=0.69) and in pT2 patients (p=0.14). In our whole database analysis, 5-YSR of pT1bNx lesions was 70% after cholecystectomy and 78% after extended cholecystectomy. Lymph node metastasis was identified in 11% of pT1b lesions. For pT2N0 lesions, overall 5-YSR was 62% after R0 resection, showing no survival difference between primary extended surgery and LC-redo operation (p=0.45). CONCLUSIONS The survival gain of reoperation was not evident in pT1b lesions. In contrast, some noticeable but not statistically significant survival difference was observed in pT2 lesions. Thus, reoperation for pT1b/T2 GBC following LC is indicated for individualized reasons, especially in patients with pT1b lesions. Old age was one of the important factors in deciding not to reoperate.

Abstract
BACKGROUND Routine histopathological examination of gallbladder specimens is mainly performed to identify unexpected gallbladder carcinoma (GBC). This systematic review assesses the prevalence and characteristics of GBC in cholecystectomy specimens. METHODS PubMed, EMBASE, Web of Science, and the Cochrane Library were searched for all articles reporting on the finding of GBC in cholecystectomy specimens. RESULTS Of the 30 articles included, 20 were from Europe and the United States, and 10 were of Asian origin. In the Western studies, 276 cases of GBC were found in 61,542 specimens (median prevalence 0.4%, 95% confidence interval [CI] 0.3-0.6). Of these, 65% were expected pre- or intraoperatively. In the Asian studies, 344 cases of GBC were found in 37,365 specimens (median prevalence 1.2%, 95% CI 0.8-1.7). Of these, 45% were expected pre- or intraoperatively. In a subgroup analysis, identification of previously unexpected GBC affected treatment in only a minority of patients. In total, 72% of the patients received no further treatment and 32 patients (22%) received secondary surgery, of whom 15 patients survived at least 1 year. CONCLUSIONS The histopathological finding of GBC after cholecystectomy appears to be a rare event. The prevalence of unexpected GBC was higher in Asian studies than in Western studies. The pre- and intraoperative sensitivity for this carcinoma is low. Moreover, the diagnosis of GBC at the time of histopathology is usually inconsequential. The results of this systematic review do not support routine histopathology of cholecystectomy specimens in clinical practice.

Abstract
Background Neurotrophic factors such as brain derived neurotrophic factor (BDNF) are synthesized in a variety of neural and non-neuronal cell types and regulate survival, proliferation and apoptosis. In addition, bone morphogenetic proteins (BMPs) inhibit the proliferation of pulmonary large carcinoma cells bone morphogenetic protein receptor, type IA (BMPR1A). Little is known about the expression of BDNF or BMPR1A in malignant gall bladder lesions. This study was to evaluate BDNF and BMPR1A expression and evaluate the clinicopathological significance in benign and malignant lesions of the gallbladder. Methods The BDNF and BMPR1A expression of gallbladder adenocarcinoma, peritumoral tissues, adenoma, polyp and chronic cholecystitis were Immunohistochemically determined. Results BDNF expression was significantly higher in gallbladder adenocarcinoma than in peritumoral tissues, adenoma, polyps and chronic cholecystitis samples. However, BMPR1A expression was significantly lower in gallbladder adenocarcinoma than in peritumoral tissues, adenomas, polyps and chronic cholecystitis tissues. The specimens with increased expression of BDNF in the benign lesions exhibited moderate- or severe-dysplasia of gallbladder epithelium. BDNF expression was significantly lower in well-differentiated adenocarcinomas with maximum tumor diameter <2 cm, no metastasis to lymph nodes, and no invasion of regional tissues compared to poorly-differentiated adenocarcinomas with maximal tumor diameter >2 cm, metastasis of lymph node, and invasiveness of regional tissues in gallbladder adenocarcinoma. BMPR1A expression were significantly higher in the well-differentiated adenocarcinoma with maximal tumor diameter <2 cm, no metastasis of lymph node, and no invasion of regional tissues compared to poorly-differentiated adenocarcinomas with maximal tumor diameter >2 cm, metastasis of lymph node, and invasiveness of regional tissues in gallbladder. Univariate Kaplan-Meier analysis indicated increased expression of BDNF or decreased expression of BMPR1A was associated with decreased disease specific survival (DSS) rates. Similarly, multivariate Cox regression analysis showed increased expression of BDNF or decreased expression of BMPR1A are independent predictors of poor DSS rates in gallbladder adenocarcinoma. Conclusions In gallbladder malignancies, the increased expression of BDNF and decreased expression of BMPR1A were associated with increased risk of metastasis, regional invasion and mortality. They might serve as novel indicators of gallbladder adenocarcinoma outcomes, which may prove valuable for the development of personalized therapeutic paradigms.
