ABSTRACT
Introducción: El adenocarcinoma de vesícula biliar es de las neoplasias digestivas con peor pronóstico; es poco común, y está asociado a una alta mortalidad. La mayoría de los diagnósticos son incidentales cuando se realiza exploración quirúrgica por sospecha de colelitiasis; encontrando malignidad en el 1 a 2% de estos casos. Produce síntomas inespecíficos, llevando a diagnósticos tardíos, empeorando así el pronóstico. Las características de esta neoplasia y el diagnóstico tardío hacen que muchas veces la resección curativa no sea posible. Caso Clínico : Paciente femenino de 45 años, quien refiere inicio de enfermedad actual (IEA) en diciembre de 2021 cuando posterior a ingesta de comida presenta dolor de aparición súbita, opresivo, de fuerte intensidad en epigastrio, intermitente. Ultrasonido abdominal (USA) reporta LOE vesicular. Se decide resolución mediante colecistectomía abierta extendida, donde se encuentra vesícula biliar (VB), con tumor en su interior que ocupa 30% de la luz, se realiza biopsia intraoperatoria, diagnosticándose ADC de vesícula. La paciente evolucionó satisfactoriamente y es egresada. En controles periódicos no hay evidencia de recidiva de la enfermedad. Conclusión : El cáncer de vesícula biliar (CVB) es una patología poco común, de difícil diagnóstico y asociado a una alta tasa de mortalidad, que produce síntomas inespecíficos por lo que es necesario un alto índice de sospecha para su diagnóstico. El manejo y conducta terapéutica depende de la extensión y el estadiaje del tumor. Es necesaria la realización de más estudios para determinar y estandarizar el manejo de esta infrecuente neoplasia(AU)
Introduction: Gallbladder adenocarcinoma is one of the digestive neoplasms with the worst prognosis; it is uncommon and is associated with high mortality. Most diagnoses are incidental when surgical exploration is performed due to suspected cholelithiasis, with malignancy found in 1 to 2% of these cases. It produces nonspecific symptoms, leading to late diagnoses, thereby worsening the prognosis. The characteristics of this neoplasm and the late diagnosis often make curative resection impossible.Clinical Case : A 45-year-old female patient who reported the onset of the current illness in December 2021. After a meal, she experienced sudden, intense, and intermittent epigastric pain. Abdominal ultrasound (US) reported gallbladder wall thickening. It was decided to perform an extended open cholecystectomy, and a tumor was found inside the gallbladder, occupying 30% of its lumen. An intraoperative biopsy was performed, diagnosing gallbladder adenocarcinoma. The patient recovered satisfactorily and was discharged. Subsequent follow-up visits have shown no evidence of disease recurrence.Conclusion : Gallbladder cancer (GBC) is a rare condition with a challenging diagnosis and a high mortality rate. It produces nonspecific symptoms, so a high index of suspicion is necessary for its diagnosis. The management and therapeutic approach depend on the tumor's extent and staging. Further studies are needed to determine and standardize the management of this uncommon neoplasm(AU)

Background: Dual specificity phosphatase 4 (DUSP4), which regulates the mitogen activated protein kinases, has emerged as a tumor suppressor gene in several human malignancies. Aims and Objectives: In this study, we investigated the clinicopathologic significance and the prognostic role of DUSP4 in gallbladder adenocarcinoma. Materials and methods: DUSP4 expression was evaluated immunohistochemically in tissue microarray from 110 gallbladder adenocarcinoma samples and scored by H score system. The cut off (H score <170) was determined by ROC curve analysis. Results: Low expression of DUSP4 expression was observed in 57 (51.8%) out of 110 gallbladder adenocarcinoma samples. Low expression of DUSP4 expression was significantly associated with high histologic grade (P = 0.017), high pT stage (P = 0.002) and high AJCC stage (P = 0.007). Kaplan Meier survival curves revealed that patients with low expression of DUSP4 expression had significantly worse cancer specific survival (P = 0.024, log rank test). However, there was no significant association between DUSP4 expression and recurrence free survival. Conclusions: In conclusion, gallbladder adenocarcinoma with low expression of DUSP4 expression was associated with adverse clinicopathologic characteristics and poor patient outcome.patient outcome.
ABSTRACT
Objective To study the impact factors on prognosis of patients with gallbladder adenocarcinoma after surgery.Methods The clinicopathological data of 1 285 patients who underwent surgery and were histologically confirmed to have gallbladder adenocarcinoma from 2004 to 2014 was extracted from the SEER database of US National Cancer Institute.Life table was used to calculate the survival rate.Kaplan-Meier was used to construct the survival curves.Univariate and Cox multivariate regression analysis were applied to evaluate the prognostic factors.The univariate analysis was evaluated by the log-rank x2 test.Results The median survival of 1 285 patients with gallbladder adenocarcinoma was 32 months.The 1-,3-and 5-year survival rates were 77.5％,46.8％ and 36.5％,respectively.The 5-year survival rates of stage Ⅰ,Ⅱ,ⅢA,ⅢB,ⅣA,ⅣB were 72.7％,63.2％,24.6％,20.5％,0 and 5.1％,respectively.The median survival of stage ⅢA,ⅢB,ⅣA and ⅣB were 22 months,19 months,12 months and 16 months,respectively.The differences were statistically significant (P ＜ O.05).Univariate analysis showed that sex,age,degree of differentiation,tumor size,T staging,N staging,number of lymph nodes detected,lymph node metastasis rate,location of lymph node metastasis,and American Joint Commission on cancer (AJCC) staging were significantly associated with prognosis (P ＜ 0.05).There was no significant differences among race and marital status with prognosis (P ＞ 0.05).Multivariate Cox regression analysis showed that sex (male),age (≥ 65 years),degree of differentiation,T staging,number of lymph nodes detected (＜ 4)and AJCC staging were independent risk factors affecting prognosis of patients with gallbladder adenocarcinoma (P ＜ 0.05).Conclusions With increase in AJCC staging,the survival rates in patients with gallbladder adenocarcinoma after surgery decreased gradually.Parameters including sex,age,T staging,number of lymph nodes detected and AJCC staging were independent factors affecting prognosis of patients with gallbladder adenocarcinoma after surgery.
ABSTRACT
Objective@#To investigate the clinical efficacy of radical resection for stage T3 gallbladder cancer and prognostic factors.@*Methods@#The retrospective case-control study was conducted. The clinico-pathological data of 87 patients with T3 gallbladder cancer who were admitted to Tianjin Medical University Cancer Institute and Hospital from January 2005 to June 2016 were collected. There were 44 males and 43 females, aged 29-79 years, with a median age of 61 years. According to the different preoperative pathological classification and intraoperative exploration of gallbladder cancer, corresponding surgeries were performed. Observation indicators: (1) surgical and postoperative conditions; (2) clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis; (3) clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis; (4) clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. Follow-up by outpatient examination or telephone interview was performed to detect the postoperative survival of patients up to June 2018. Measurement data with skewed distribution were represented as M (range), and count data were described as absolute numbers. Survival curve, survival time and survival rate were drawn and calculated by the Kaplan-Meier method. Survival analysis was performed by the Log-rank test. Univariate analysis was performed using the Log-rank test and multivariate analysis using the COX proportional hazard model.@*Results@#(1) Surgical and postoperative conditions: all the 87 patients underwent radical resection of gallbladder cancer, including 29 cases of hepatic wedge resection and 58 cases of extended hepatectomy. Of the 87 patients, 42 underwent standard lymph node dissection and 45 underwent enlarged lymph node dissection. There were 27 cases receiving extrahepatic bile duct reconstruction. The postoperative pathological results of 87 patients showed that 64 were diagnosed with gallbladder adenocarcinoma and 23 were diagnosed with gallbladder adenosquamous carcinoma. There were 59 cases comorbid with liver invasion and 3 cases comorbid with vascular invasion. The marginal histopathological examination showed negative margin in 63 cases and positive margin in 24 cases. The degree of tumor differentiation: there were 23 patients with highly differentiated tumor and 64 with poorly differentiated tumor. Of the 87 patients, 43 received postoperative adjuvant therapy and 44 didn′t receive adjuvant therapy. (2) Clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis. ① All the 87 patients were followed up for 1.8-128.0 months, with a median follow-up time of 26.3 months. All the 87 patients had survived for 1.1-82.7 months, with a median time of 20.1 months. The 2-year overall survival rate of patients was 59.8%, and the 2-year disease-free survival rate was 49.4%. ② Univariate analysis showed that preoperative alkaline phosphatase (ALP) level, tumor diameter, pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.451, 4.900, 8.256, 4.419, 5.858, P<0.05), and pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=5.828, 6.968, 4.077, P<0.05). Multivariate analysis showed that preoperative ALP level, tumor diameter, and lymph node metastasis were independent factors influencing the postoperative 2-year overall survival rate of patients [hazard ratio (HR)=2.539, 2.619, 2.201, 95% confidence interval (CI) : 1.174-5.491, 1.209-5.673, 1.104-4.391, P<0.05)]; pathological type of tumor and lymph node metastasis were independent factors influencing the postoperative 2-year disease-free survival rate of patients (HR=2.254, 2.296, 95%CI: 1.170-4.344, 1.206-4.374, P<0.05). ③ Survival analysis: pathological type of tumor was an associated factor for the postoperative 2-year overall survival rate and 2-year disease-free survival rate of patients. Of the 87 patients with T3 gallbladder cancer, there was no significant difference in the postoperative 2-year overall survival rate between the 64 patients with gallbladder adenocarcinoma and 23 with gallbladder adenosquamous carcinoma (68.8% vs. 34.8%, χ2=8.256, P>0.05), but a significant difference in the postoperative 2-year disease-free survival rate between them (56.3% vs. 30.4%, χ2=5.828, P<0.05). (3) Clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis. ① Sixty-four patients with gallbladder adenocarcinoma had the median survival time of 23.1 months, with a range from 3.2 to 82.7 months. The postoperative 2-year overall survival rate was 68.8%, and the postoperative 2-year disease-free survival rate was 56.3%. ② For the 64 patients with T3 stage gallbladder adenocarcinoma, univariate analysis showed that preoperative CA19-9 level and range of lymph node dissection were associated factors for the postoperative 2-year overall survival rate (χ2=4.012, 8.837, P<0.05). The range of lymph node dissection was an associated factor for the postoperative 2-year disease-free survival rate (χ2=6.361, P<0.05). Multivariate analysis showed that range of lymph node dissection was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.244, 0.382, 95%CI: 0.088-0.674, 0.176-0.831, P<0.05). ③ Survival analysis: range of lymph node dissection was an associated factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 64 patients with T3 stage gallbladder adenocarcinoma, the postoperative 2-year overall survival rate and disease-free survival rate of patients undergoing enlarged lymph node dissection were 84.8% and 69.7%, versus 51.6% and 41.9% of the patients undergoing standard lymph node dissection (χ2=8.837, 6.361, P<0.05). (4)Clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. ① Twenty-three patients with gallbladder adenosquamous carcinoma had the median survival time of 13.2 months, with a range from 1.1 to 70.3 months. The postoperative 2-year overall survival rate was 34.8%, and the postoperative 2-year disease-free survival rate was 30.4%. ② For the 23 patients with T3 stage gallbladder adenosquamous carcinoma, univariate analysis showed that preoperative ALP level, lymph node metastasis, range of hepatectomy, and extrahepatic bile duct reconstruction were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.288, 4.574, 12.960, 4.106, P<0.05). The lymph node metastasis and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=7.364, 10.582, P<0.05). Multivariate analysis showed that range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.102, 0.153, 95%CI: 0.012-0.880, 0.033-0.718, P<0.05). ③ Survival analysis: range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 23 patients with T3 stage gallbladder adenosquamous carcinoma, the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients undergoing extended hepatectomy were 87.5% and 75.0%, versus 6.7% and 6.7% of the patients undergoing hepatic wedge resection (χ2=12.960, 10.528, P<0.05).@*Conclusions@#Lymph node metastasis is an independent factor influencing the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with T3 stage gallbladder cancer. The range of lymph node dissection is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenocarcinoma. Range of hepatectomy is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenosquamous carcinoma. Patients with gallbladder adenocarcinoma should undergo enlarged lymph node dissection, and patients with gallbladder adenosquamous carcinoma need to undergo extended hepatectomy.

ABSTRACT
Os cistos de colédoco são dilatações congênitas dos ductos biliares, que podem ser extra-hepáticos e/ou intra-hepáticos. Mais prevalentes no sexo feminino e na maioria dos casos diagnosticados até a primeira década de vida. É uma entidade pouco frequente que, quando diagnosticada na população adulta, cursa com uma grande frequência de complicações, devendo-se estar atento em especial ao seu alto risco de malignização. Os autores descrevem o caso de uma paciente de 35 anos, do sexo feminino, que iniciou um quadro de dor abdominal inespecífica, sendo identificado um cisto de colédoco associado ao adenocarcinoma de vesícula biliar.
Choledochal cysts are congenital dilatation of the bile ducts, which can be extrahepatic or intrahepatic. They are more prevalent in women, and in most cases diagnosed until the first decade of life. They are a less common entity that, when diagnosed in the adult population, attends with a high frequency of complications, what makes important to be specially attentive to its high risk of malignant transformation. The authors describe the case of a 35 year-old female patient, who started an unspecific abdominal pain, being identified a choledochal cyst associated to a gallbladder adenocarcinoma.

Presentamos tres casos de pacientes femeninos que acuden al servicio de imagenología para la realización de exámenes ecográficos de hígado y vías biliares.Recordamos que la vesícula biliar es una bolsa cerrada, en forma de pera, que descansa bajo la superficie inferior del hígado. La fosa vesicular se encuentra en el plano de la fisura interlobular que separa a los lóbulos hepáticos derecho e izquierdo. El cáncer de vesícula biliar es poco común, pero el carcinoma es el tumor maligno más frecuente y su tipo histológico habitual es en un 90% de los casos, un adenocarcinoma. No obstante en la vesícula biliar se han descrito carcinomas: epidermoides y mixtos, y sarcomas.
We present three cases of female patients admitted to our service where liver and bile duct ecography is done.The gallbladder is a pear-shaped organ that lies just under the liver in the upper abdomen. Cancer of the gallbladder is uncommon. The most frequent type of tumor is andenocarcinoma but others have been described such as epidermoid carcinoma and sarcomas.

Objective To study the expressions of CA19-9 and CA125 and their clinicopathologic significances in gallbladder adenocarcinoma, pericancerous tissues and chronic cholecystitis. Methods EnVisionTM immunohistochemistry was used for assaying the expressive levels of CA19-9 and CA125 in the routinely paraffin-embedded sections of specimens from gallbladder adenocarcinoma (n=108), pericancerous tissues (n=46), and chronic cholecystitis (n=35). Results The positive rates of CA19-9 and CA125 were significantly higher in gallbladder adenocarcinoma (49.1%, 51.9%) than those in pericancerous tissues (26.1%, 15.2%) and chronic cholecystitis (14.3%, 5.7%), respectively (P
