RESUMO

The management of pancreatic ductal adenocarcinoma (PDAC) is a major public health concern worldwide. Currently, most PDAC patients are diagnosed in advanced stages. The signs and symptoms of the disease, except for jaundice, are non-specific. Thus, the current challenge is to identify earlier those individuals for whom specific screening tools and specific treatments would be beneficial. On the basis of the recommendations of the group of experts of multiple medical specialties of the GALLgo Project, the patients with PDAC should be managed by a multidisciplinary team to assess the personal and family history, the best diagnostic and staging procedures and consider all important aspects for treatment decisions. In this article, the group of experts proposes strategies to shorten the diagnosis times in PDAC patients (AU)

RESUMO

The management of patients with pancreatic cancer has advanced over the last few years. We convey a multidisciplinary group of experts in an attempt to stablish practical guidelines for the diagnoses, staging and management of these patients. This paper summarizes the main conclusions of the working group. Patients with suspected pancreatic ductal adenocarcinoma should be rapidly evaluated and referred to high-volume centers. Multidisciplinary supervision is critical for proper diagnoses, staging and to frame a treatment plan. Surgical resection together with chemotherapy offers the highest chance for cure in early stage disease. Patients with advanced disease should be classified in treatment groups to guide systemic treatment. New chemotherapeutic regimens have resulted in improved survival. Symptomatic management is critical in this disease. Enrollment in a clinical trial is, in general, recommended.

RESUMO

Objetivo: El objetivo del estudio es presentar nuestra experiencia inicial con el sistema estereotáctico de fusión de imagen ECO-RM para el diagnóstico de cáncer de próstata. Material y métodos: Entre septiembre de 2014 y enero de 2015 se realizaron 50 biopsias de próstata mediante el sistema estereotáctico de fusión de imagen ECO-RM. Las imágenes de RM multiparaméticas 3 Tesla (RM3T) se superpusieron mediante este sistema de fusión de imagen sobre las imágenes de ECO3D obtenidas con el sistema Biopsee para la localización exacta de las zonas de sospecha de cáncer de próstata. Las lesiones se clasificaron mediante el sistema Prostate Imaging Report and Data System. Resultados: Se valoraron un total de 50 pacientes, edad media de 63 años (rango 45-79), PSA medio 8 ng/ml (rango 1,9-20) y un volumen prostático medio de 52 ml (rango 12-118). Se diagnosticó cáncer de próstata en el 69% de los pacientes, neoplasia intraepitelial (PIN) en el 6% y la biopsia resultó negativa en el 24%. Un 62% de los pacientes tenía coincidencia entre la biopsia y la RM, pero un 46% presentó tumor también fuera de la lesión sospechosa. Se diagnosticaron un 46% de tumores anteriores y un 33% de tumores apicales. Un paciente presentó hematuria, otro un hematoma y un tercero retención aguda de orina. Conclusiones: La RM prostática multiparamétrica permite identificar lesiones de próstata sugestivas de cáncer. El sistema Biopsee de fusión de imagen ECO-RM permite su biopsia dirigida y aumenta el rendimiento diagnóstico, reduce los falsos negativos de las biopsias tradicionales y aumenta el diagnóstico de tumores anteriores. El acceso transperineal minimiza el riesgo de infección prostática o sepsis


Objective: The aim of this study is to present our initial experience with the stereotactic echo-MRI fusion system for diagnosing prostate cancer. Material and methods: Between September 2014 and January 2015, we performed 50 prostate biopsies using the stereotactic echo-MRI fusion system. The 3-Tesla multiparameter MR images were superimposed using this image fusion system on 3 D echo images obtained with the Biopsee system for the exact locating of areas suspected of prostate cancer. The lesions were classified using the Prostate Imaging Report and Date System. Results: We assessed a total of 50 patients, with a mean age of 63 years (range, 45−79), a mean prostate-specific antigen level of 8 ng/mL (range, 1.9−20) and a mean prostate volume of 52 mL (range, 12-118). Prostate cancer was diagnosed in 69% of the patients and intraepithelial neoplasia in 6%. The results of the biopsy were negative for 24% of the patients. The results of the biopsy and MRI were in agreement for 62% of the patients; however, 46% also had a tumour outside of the suspicious lesion. We diagnosed 46% anterior tumours and 33% apical tumours. One patient had a haematuria, another had a haematoma and a third had acute urine retention. Conclusions: Multiparametric prostatic MRI helps identify prostate lesions suggestive of cancer. The Biopsee echo-MRI fusion system provides for guided biopsy and increases the diagnostic performance, reducing the false negatives of classical biopsies and increasing the diagnosis of anterior tumours. Transperineal access minimises the risk of prostatic infection and sepsis

RESUMO

OBJECTIVE: Surveillance programmes are recommended for individuals at risk (IAR) of familial pancreatic cancer (FPC) to detect early pancreatic cancer (pancreatic ductal adenocarcinoma, PDAC). However, the age to begin screening and the optimal screening protocol remain to be determined. METHODS: IAR from non-CDKN2A FPC families underwent annual screening by MRI with endoscopic ultrasonography (EUS) in board-approved prospective screening programmes at three tertiary referral centres. The diagnostic yield according to age and different screening protocols was analysed. RESULTS: 253 IAR with a median age of 48 (25-81) years underwent screening with a median of 3 (1-11) screening visits during a median follow-up of 28 (1-152) months. 134 (53%) IAR revealed pancreatic lesions on imaging, mostly cystic (94%), on baseline or follow-up screening. Lesions were significantly more often identified in IAR above the age of 45 years (p<0.0001). In 21 IAR who underwent surgery, no significant lesions (PDAC, pancreatic intraepithelial neoplasia (PanIN) 3 lesions, high-grade intraductal papillary mucinous neoplasia (IPMN)) were detected before the age of 50 years. Potentially relevant lesions (multifocal PanIN2 lesions, low/moderate-grade branch-duct IPMNs) occurred also significantly more often after the age of 50 years (13 vs 2, p<0.0004). The diagnostic yield of potentially relevant lesions was not different between screening protocols using annual MRI with EUS (n=98) or annual MRI with EUS every 3rd year (n=198) and between IAR screened at intervals of 12 months (n=180) or IAR that decided to be screened at ≥24 months intervals (n=30). CONCLUSIONS: It appears safe to start screening for PDAC in IAR of non-CDKN2a FPC families at the age of 50 years. MRI-based screening supplemented by EUS at baseline and every 3rd year or when changes in MRI occur appears to be efficient.

RESUMO

PURPOSE: To describe the organisation of the registry and the preliminary results in terms of characteristics of high-risk pancreatic ductal adenocarcinoma (PDAC) families recruited to date and findings of the screening programme. To compare early onset sporadic cases (⩽50 years), sporadic cases (>50 years) and cases with family history of cancer, for PDAC possible risk factors. METHODS/PATIENTS: Families with hereditary cancer syndromes predisposing to PDAC were recruited from two main sources: Spanish hospitals participating in PanGenEU, a pan-European multicentre case-control study, and their genetic counseling unit. Individuals at high-risk of PDAC were enrolled into a screening programme, consisting of Endoscopic ultrasound, computerised tomography, magnetic resonance imaging. Genetic testing of candidate genes was offered according to each patient's risk. RESULTS: Among 577 consecutive PDAC cases, recruited via PanGenEU, 36 (6%) had ⩾2 first-degree relative with PDAC: Familial pancreatic cancer (FPC). So far PanGen-Fam has recruited 42 high-risk PDAC families; 25 (60%) had FPC. Five index cases with cancer were positive for BRCA2 and one for BRCA1 germline mutations. In the second year of prospective PDAC screening, one neuroendocrine tumour and a high-grade dysplasia lesion suspicious of carcinoma were diagnosed among 41 high-risk individuals. Furthermore EUS detected chronic-pancreatitis-like parenchymal changes in 15 patients. CONCLUDING STATEMENT: The identification and recruitment of PDAC high-risk families into the PanGen-Fam registry provides an opportunity to detect early onset cancer and precursor pancreatic cancer lesions at a potentially curative stage and to increase the knowledge of the natural history of the disease.
