RESUMO

The purpose of this study was to investigate the potential prognostic value of preoperative lymphocyte-to-monocyte ratio (LMR) and establishment of a prognostic nomogram in post surgical patients with gallbladder carcinoma (GBC).Receiver operating characteristic curve analysis was performed to determine the optimal cut-off value of LMR. The correlation between preoperative LMR and overall survival (OS) was analyzed using univariate and multivariate Cox regression analyses. A relevant prognostic nomogram was established.Three hundred fifteen GBC patients were retrospectively enrolled. Based on receiver operating characteristic curve analysis, the optimal cutoff value of LMR was 2.685. Patients were categorized into high-LMR group (n = 143) or low-LMR group (n = 172). Low-LMR value was significantly associated with elderly age, advanced tumor, and the performance of a palliative cholecystectomy. The results of the univariate and multivariate analyses eliminated the degree of tumor differentiation, tumor-node-metastasis stages, surgery types, and LMR as independent predictors of OS. Based on those independent predictors, a predictive nomogram for OS was generated with an accuracy of 0.848.Based on our findings, the predictive nomogram should be included in the routine assessment of GBC patients.

RESUMO

Incidental gallbladder cancer(IGBC) originated in the West more than half a century ago.IGBC was translated and introduced into China afterwards with widespread clinical application.With the popularization of laparoscopic cholecystectomy, the trend of "abuse" of IGBC has become increasingly apparent worldwide.Many advanced gallbladder cancers have been categorized as IGBC which actually become the synonym of "missed diagnosis" . From the point of the pathology, the diagnosis of IGBC may cause delays in treatment and adversely affect the patient's prognosis.For country like China with relatively high incidences of chronic cholecystitis, cholelithiasis, and gallbladder cancer, the concept of IGBC, however, is no longer applicable to our diagnosis treat model.For improving the prognosis of gallbladder patients, it is necessary to update and rename the concept of IGBC and more attention should be paid to improve the diagnostic level of early stage tumor.

RESUMO

Gallbladder carcinoma (GBC) is the most common malignancy of the biliary tract, radical resection is the only effective treatment for GBC at present. However, the postoperative effect is still poor. Therefore, identifying the key prognostic factors and establishing an individual and accurate survival prediction model for GBC are critical to prognosis assessment, treatment options and clinical decision support in patients with GBC. The prediction value of current commonly used TNM staging system is limited. Cox regression model is the most commonly used classical survival analysis method, but it is difficult to establish the association between prognostic variables. Nomogram and machine learning techniques including Bayesian network have been used to establish survival prediction model of GBC in recent years, which representing a certain degree of advancement, however, the model precision and clinical application still need to be further verified. The establishment of more accurate survival prediction models for GBC based on machine learning algorithm from Chinese multicenter large sample database to guide the clinical decision-making is the main research direction in the future.

RESUMO

Resumen El cáncer de vesícula es infrecuente a nivel mundial, a diferencia de su alta incidencia en Chile. Su pronóstico es malo en general, y dependerá de su forma de presentación, siendo mejor en los casos diagnosticados después de una colecistectomía laparoscópica por patología benigna. La reintervención, que incluye la resección hepática y linfadenectomía, es el pilar de la terapia curativa en esta neoplasia. Presentamos la descripción de la técnica quirúrgica realizada en los pacientes con cáncer de vesícula de diagnóstico incidental, en el Servicio de Cirugía de Clínica Alemana de Santiago y en el Hospital de la Fuerza Aérea de Chile. El abordaje laparoscópico representa una alternativa quirúrgica válida en el tratamiento de pacientes con cáncer de vesícula biliar diagnosticados después de la colecistectomía. La estandarización de la técnica debiera contribuir a su mayor empleo y a la obtención de buenos resultados desde un punto de vista oncológico.


Gallbladder cancer is considered an infrequent disease but in Chile has a higher incidence. Prognostic is considered dismal except in those patients in whom the diagnosis is performed after the cholecystectomy specimen study. Reoperation with gallbladder bed resection and lymphadenectomy is considered the treatment in patients with incidental cases. We show the way this operation is performed in Clinica Alemana of Santiago and in the Air Force Hospital. The laparoscopic approach is an alternative to those patients in whom the diagnosis was done after the cholecystectomy. Laparoscopy allows to accomplish same objectives and to obtain identical results that the open approach. The technical standardization should contribute to spread its employment and to improve the results.

RESUMO

OBJECTIVE: To study the incidence of gallbladder polyps and the possibilities of modern methods of diagnosis and surgical treatment of this disease. MATERIAL AND METHODS: There were 42 laparoscopic cholecystectomies in patients with diagnosed gallbladder polyps. The polyps were diagnosed preoperatively. Intraoperative diagnosis during surgery for gallstone disease was observed in 3 cases. A comparative analysis of preoperative examination did not reveal any advantages of certain diagnostic approach. RESULTS: Hyperplastic polyp was the most common type (n=20, 47.6%), adenomatous polyps occurred in 19 (45.3%) cases, cholesteric polyps - in 3 (7.1%) patients. All patients had signs of chronic inflammation of the gallbladder wall with its infiltration by lymphocytes and histiocytes. CONCLUSION: Further studies with clear criteria for the diagnosis of gallbladder polyps including ones for determining true polyps, precancerous and malignant polyps are required.

RESUMO

The role of laparoscopic radical cholecystectomy (LRC) in the surgical management of T2 gallbladder carcinoma (GBC) is still controversial.The medical records of patients with T2 GBC treated with radical cholecystectomy were retrospectively reviewed. In this study, we compare the short- and long-term oncologic outcomes, using propensity score matching analysis, of patients with T2 GBC who underwent LRC and open radical cholecystectomy (ORC).Among 183 patients, 86 were selected by propensity score matching (LRC = 43 and ORC = 43). The ORC group underwent more extensive surgery (liver resections and extended lymph node dissections [ELND]) than the LRC group. The LRC group had less operative blood loss, shorter length of hospital stay, fewer complications, and had the earlier start of adjuvant chemotherapy. There was no significant difference between the laparoscopic and open surgery groups in terms of 5-year overall survival rate (64.6% vs 80.4%, P = .214) and disease-free survival rate (77.1% vs 82.2%, P = .641). A subgroup analyses showed that liver resection and ELND had no survival advantage compared to no liver resection and regional lymph node dissection, respectively.Our LRC approach is safe and effective, with long-term survival comparable to that of ORC.

RESUMO

BACKGROUND AND OBJECTIVES: Gallbladder carcinoma (GBC) has a poor prognosis. Studies demonstrated that teaching facilities may provide a lower risk of mortality in patients undergoing pancreatic and colon resection vs nonteaching facilities. We hypothesized that survival rates are higher in academic cancer centers (ACCs) vs community cancer centers (CCCs). METHODS: Patients with all stages of GBC were identified from the National Cancer Database (2007-2012). Propensity score matching adjusted for selection bias. Descriptive statistics were calculated for all variables. Overall survival (OS) was compared by facility type (ACC vs CCC) and case volume (low vs high) via multivariable Cox proportional hazards regression. RESULTS: A total of 7967 patients met the inclusion criteria. Following propensity matching, 2801 patients were analyzed from each facility type. Median OS following surgery was higher for ACC (20.99 months, 95% confidence interval [CI], 19.61-22.64, P = .002) than CCC (17.68 months, 95% CI, 16.46-19.25). Following Cox modeling, GBC treatment at ACCs was a protective factor for OS (adjusted hazard ratio 0.876, 95% CI, 0.801-0.958, P = .004). DISCUSSION: GBC treatment at ACCs is an independent predictor of OS. High volume ACCs are associated with improved OS compared with low volume ACCs. The site of care and case volume in ACCs may contribute to improved survival outcomes.

RESUMO

Objective: To examine the role of the number of lymph nodes examined(NLNE) on the prognosis of patients with curatively resected gallbladder carcinoma(GBC). Methods: The clinicopathological data and prognosis of 401 patients with GBC who underwent radical surgery from six institutions of China from January 2013 to December 2017 were analyzed retrospectively. There were 153 males(38.2%) and 248 females(61.8%), with age of (62.0±10.5) years (range: 30-88 years). Fifty-three patients(22.2%) were accompanied by jaundice. All patients underwent radical resection+regional lymphadenectomy.R0 or R1 resection was confirmed by postoperative pathological examination.The different cut-off values of NLNE were determined by the X-tile software, the optimal cut-off values were identified by analyzing the relationship between different cut-off values of NLNE with survival rate. Kaplan-Meier method was used for survival analysis. Univariate and multivariate analysis were implemented respectively using the Log-rank test and Cox proportional hazard model. Results: Among the 401 patients enrolled, 135 cases (33.6%) had lymphatic metastasis, of which 98 cases were in N1 stage(24.4%) and 37 cases were in N2 stage(9.2%).A total of 2 794 NLNE were retrieved, with a median count of 6 (5).The median positive lymph nodes count was 0 (1), and the median positive lymph nodes ratio was 0 (IQR, 0-0.2). Since the 12 and 15 were determined as the cut-off values by X-tile, all patients were divided into three groups of 1-11, 12-15 and ≥16.The 3-year survival rate of the three groups was 45.2%, 74.5%, 12.0% respectively, with statistically significant difference between three groups (χ(2)=10.94, P<0.01). The results of multivariate analysis showed that NLNE was an independent prognostic factor for overall survival (P<0.05). Further analysis was performed specifically for subgroup of T stages. For T1b patients, the prognosis of the NLNE with 1-7 group was significantly better than that of the ≥8 group(χ(2)=4.610, P<0.05). For T2 patients, the prognosis of the TLNE ≥7 group was significantly better than that of 1 -6 group (χ(2)=4.287, P<0.05). For T3 and T4 patients, the prognosis of the TLNE with 12 - 15 group was significantly better than that of 1 -11 group (χ(2)=5.007, P<0.01) and ≥16 group (χ(2)=10.158, P<0.01). Conclusions: The NLNE is an independent factor affecting the prognosis of patients with GBC.For patients with stage T1b,8 lymph nodes should be retrieved; for patients with stage T2,extensive dissection of more than 6 lymph nodes can significantly improve the prognosis.For advanced patients (stages T3 and T4), extensive dissection with 12-15 lymph nodes is recommended. However, it fails to get more survival benefits by dissecting more than 16 lymph nodes.

RESUMO

BACKGROUND: Few reports have addressed postoperative infectious complications caused by multidrug-resistant pathogens. The aim of this study was to review the surgical outcomes of patients undergoing major hepatectomy with extrahepatic bile duct resection and to clarify the incidence of and the risk factors for postoperative infectious complications caused by multidrug-resistant pathogens. METHODS: Medical records of consecutive patients who underwent major hepatectomy with extrahepatic bile duct resection between 2006 and 2017 were retrospectively reviewed. RESULTS: Among 620 study patients, 219 had postoperative infectious complications, including 62 (10.0%) with postoperative infectious complications caused by multidrug-resistant pathogens. The mortality of the 62 patients with postoperative infectious complications caused by multidrug-resistant pathogens was higher (n = 8, 12.9%) than that in the 157 patients with postoperative infectious complications caused by non-multidrug-resistant pathogens(n = 2, 1.3%) (P < .001). With multivariate analysis, the presence of preoperative cholangitis, the extent of liver resection more than 50%, operative time longer than 600 minutes, the amount of blood loss more than 1500 mL, and the presence of postoperative infectious complications caused by multidrug-resistant pathogens were identified as independent risk factors for postoperative death. The presence of multidrug-resistant pathogens in preoperative bile culture, the amount of blood loss greater than 1500 mL, the presence of bile leakage, and pancreatic fistula were identified as independent risk factors for postoperative infectious complications caused by multidrug-resistant pathogens. CONCLUSION: The incidence of postoperative infectious complications caused by multidrug-resistant pathogens in patients undergoing major hepatectomy with extrahepatic bile duct resection is high, approximately 10%. This troublesome complication is closely associated with postoperative death. Thus, preventing postoperative infectious complications caused by multidrug-resistant pathogens is an urgent task to improve surgical outcome after major hepatectomy with extrahepatic bile duct resection.

RESUMO

A haemocholecyst is a clot-filled gallbladder caused by bleeding into its lumen. It is a rare entity with fewer than 50 cases reported in the English literature. Preoperative diagnosis is often not possible even with good quality cross-sectional imaging. Here, we present a case of a gallbladder mass, whose nature was only made clear at operation, where a hugely enlarged gallbladder was found filled with blood clots. There was neither liver infiltration nor regional lymphadenopathy. The clinical status of the patient demanded simple cholecystectomy. Histopathological examination, however, revealed a gallbladder adenocarcinoma, infiltrating the perimuscular connective tissue. Thus, more radical surgery was performed eight weeks later. At the 21-month follow-up, the patient was found to be well.

RESUMO

BACKGROUND: Squamous cell/adenosquamous carcinoma (SC/ASC) is a rarely identified form of gallbladder cancer with poorly understood clinical features. As such, there is an urgent need to identify novel prognostic biomarkers for such gallbladder SC/ASC cases, and for gallbladder adenocarcinomas (ACs). METHODS: The levels of ACO2 and ANPEP proteins were assessed via an EnVision-based immunohistochemical approach using 46 SC/ASC and 80 AC patient samples. RESULTS: There was a marked reduction in levels of ACO2 and ANPEP in gallbladder AC relative to normal adjacent tissue or benign gallbladder lesions. The was a significant correlation between lack of ACO2 and ANPEP and larger tumors, higher tumor-node-metastasis (TNM) staging, invasion, metastasis to regional lymph nodes, and ineligibility for surgical resection in both SC/ASC and AC tumor samples. Kaplan-Meier survival analyses further confirmed a relationship between ACO2 and ANPEP negativity and decreased overall survival in patients with these diseases (p < 0.05 or p < 0.01), and a multivariate regression analysis further established that ACO2 negativity and ANPEP negativity were independently predictive of poor SC/ASC and AC patient outcomes. CONCLUSIONS: ACO2 and ANPEP may have key physiological relevance in cancers of the gallbladder and thus warrant investigation as prognostic biomarkers.

RESUMO

OBJECTIVE: to comparatively analyse the incidence of incidental gallbladder cancer in emergency cholecystectomies versus in elective cholecystectomies performed in public hospitals in Teresina city, Piaui state (PI). METHODS: descriptive, quantitative, observational, cross-sectional study, whose scenarios were two public hospitals in Teresina-PI. We analysed 6,329 medical records of patients undergoing cholecystectomy between January 2011 and December 2017. The collected data were divided into two groups and statistically compared using Z-test for difference between proportions. RESULTS: incidental gallbladder cancer was detected in 6.53% of emergency cholecystectomies and in 0.38% of elective ones. Regarding gender, it was observed that in emergency surgeries 69% of patients were women and 31% men, while in elective procedures 78% were women and 22% men. Regarding age, most patients were over 60 years old, and, among these, 69.3% underwent emergency cholecystectomies and 82.6% underwent elective cholecystectomies. The histopathological type "adenocarcinoma" was found in 84.6% of patients who underwent emergency surgeries and in 100% of patients who underwent elective surgeries. CONCLUSION: incidental gallbladder cancer was more frequent in urgent cholecystectomies compared to elective cholecystectomies. The profile of patients with this malignant disease in both types of procedure was female, older than 60 years, and with histopathological diagnosis of adenocarcinoma.

RESUMO

BACKGROUND: Gallbladder cancer is rare but associated with significant morbidity and mortality necessitating the early identification of premalignant and malignant lesions to improve overall prognosis. Despite limited evidence regarding the effectiveness of transabdominal ultrasound (US) in the detection of gallbladder polyps, it plays a key role in current European guidelines. The aim of this study was to investigate gallbladder polyp prevalence in a western European population and assess the diagnostic accuracy of transabdominal US. METHODS: Data from patients who underwent cholecystectomy for US detected gallbladder polypoid lesions at four hospitals in Ireland and the United Kingdom between 2010 and 2018 were retrospectively collected. Patient demographics, ultrasonographic, and histopathologic findings were analyzed. RESULTS: A total of 134 patients underwent cholecystectomy for US-detected gallbladder polyps. After histopathologic examination, pseudopolyps were found in 75 (56%) specimens with dysplastic or malignant polyps seen in only six (4.5%) specimens. Mean size for neoplastic polyps was 33 mm. The positive predictive value for US in detecting neoplastic polyps in this study was 4.5%, which is significantly lower than the 10%-15% reported previously. CONCLUSIONS: Although the prevalence of neoplastic polyps in this study is higher than in the previous literature, the distribution of pseudopolyps and true polyps is as expected. With all malignant polyps being >10 mm in diameter, these findings support the current size thresholds stated in European guidelines. The poor diagnostic accuracy of US demonstrated may have led to significant number of patients undergoing unnecessary surgical intervention, further supporting the argument for improved strategies for the investigation of gallbladder polyps.

RESUMO

AIMS: Although incidental gallbladder cancer (IGBC) diagnosed after laparoscopic cholecystectomy (LC) is not rare, its incidence, management, and prognosis are still unclear and controversial. The present study aimed to increase the understanding of IGBC after LC in the medical community. METHODS: Patients with IGBC treated at our institution between January 2001 and December 2018 were enrolled. Data collected included demographic characteristics, treatment pattern, pathological information, and prognoses. We compared the characteristics of patients with different prognoses and calculated the cumulative overall survival rate and mean survival period for IGBC. RESULTS: The cohort comprised 26 patients with a mean age of 66.4 ± 12.5 years. All patients were diagnosed with IGBC via postoperative pathology. Three patients underwent radical reoperation. As of June 2019, 26 patients were followed for a mean of 31.6 ± 29.6 months. Fourteen patients died during the follow-up period, and 12 survived without recurrence. The mean survival duration was 50.5 months. The 1-, 3-, and 5-year cumulative overall survival rates of the entire cohort were 79.8, 49.0, and 40.8%, respectively. IGBC patients with T1a stage had significantly longer survival than those with T1b or more advanced stages (96.1 vs 32.6 months, P = .006). CONCLUSIONS: IGBC after LC is diagnosed in 0.2% of patients, accounting for 5.4% of all gallbladder cancer cases. IGBC patients with T1a stage had significantly longer survival than those with T1b or more advanced stages. Simple cholecystectomy is probably acceptable only in T1a lesions.

RESUMO

Inflammatory myofibroblast tumour (IMT) is an uncommon soft tissue tumour with an unpredictable clinical course: mostly benign, occasionally locally aggressive and rarely capable of metastasis. Diagnosed mainly in the mesentery, omentum, retroperitoneum, pelvis and lungs, IMT is extremely rare as a primary gallbladder tumour. Despite improved radiographical capabilities, differentiating the tumour from other more common causes of gallbladder neoplasms necessitates histopathological and immunohistochemistry tests. Once diagnosed, malignant potential should be taken into consideration, striving for an en bloc R0 resection and postoperative long-term follow-up with routine ancillary imaging. The authors present the case of a recurrent primary IMT of the gallbladder, after two surgical treatments, including a pancreaticoduodenectomy. Now 3 years after initial diagnoses the patient is asymptomatic, but has developed local and distant metastases and is being treated with systemic corticosteroid.

RESUMO

BACKGROUND: The survival benefit of lymphadenectomy among patients with gallbladder cancer (GBC) remains poorly understood. METHODS: Patients who underwent resection for GBC between 2000 and 2015 were identified from a US multi-institutional database. The therapeutic index (LNM rate multiplied by 3-year overall survival [OS]) was determined to assess the survival benefit of lymphadenectomy. RESULTS: Among 449 patients, less than half had LNM (N = 183, 40.8%). The median number of evaluated and metastatic lymph nodes (LNs) was 3 (interquartile range [IQR]: 1-6) and 1 (IQR: 0-1), respectively. 3-year OS among patients with LNM in the entire cohort was 26.8%. The therapeutic index was lower among patients with T4 (5.9) or T1 (6.0) tumors as well as carbohydrate antigen (CA19-9) ≥200 UI/mL (6.0). Of note, a therapeutic index difference ≥10 was noted relative to CA19-9 (<200: 18.7 vs ≥200: 6.0), American Joint Committee on Cancer T Stage (T1: 6.0 vs T2: 17.8 vs T4: 5.9) and number of LNs examined (1-2: 6.9 vs ≥6: 16.9). Concomitant common bile duct resection was not associated with a higher therapeutic index among patients with either T2 or T3 disease. CONCLUSION: Certain clinicopathological factors including T1 or T4 tumor and CA19-9 ≥200 UI/mL were associated with a low therapeutic index. Resection of six or more LNs was associated with a meaningful therapeutic index benefit among patients with LNM.

RESUMO

OBJECTIVE: to describe the histological findings of the gallbladders of patients undergoing cholecystectomy and to evaluate the presence of factors associated with gallbladder incidental cancer. METHODS: we conducted a descriptive, cross-sectional, observational study with 1,278 histopathological exams of gallbladders coming from cholecystectomy for cholelithiasis and of their reports, held from January 2008 to December 2017. RESULTS: the most common pathological finding was chronic cholecystitis, present in 1,251 patients (97.8%), followed by gallbladder cholesterolosis, in 131 (10.2%). Gallbladder cancer was identified in six patients, with a prevalence of 0.5% in this sample. There was a significant association between the presence of cancer and age ≥60 years and wall thickness ≥0.3cm. CONCLUSION: there was low prevalence of gallbladder cancer in this population, higher occurrence in the elderly and association of the tumor with gallbladder wall thickness.
