Pay attention to whole cycle management of pancreatic cancer / 中华外科杂志

The prognosis for pancreatic cancer is extremely poor. To improve the prognosis of pancreatic cancer, it is urgently needed to improve early detection to advance treatment. And basically, it is also necessary to emphasise basic research to find novel therapies. By promoting the disease-centered multidisciplinary team model, researchers should achieve high-quality closed-loop process management of the entire life cycle which consists of prevention, screening, diagnosis, treatment, rehabilitation,and follow-up, with the objective of establishing a standard clinical process to improve the outcome in essence. This article summarized the progress of pancreatic cancer at different stages of the whole cycle management recently and shared the experience of pancreatic cancer treatment from the author's team in the past ten years.

Ten directions for improving clinical therapeutic effect of pancreatic cancer in the future / 中华外科杂志

Pancreatic cancer is one of the most malignant digestive system tumors. In the recent decade, the effect of diagnosis and treatment of pancreatic cancer has improved due to the renewal of treatment concept and the popularization of effective treatment. However, the overall efficacy of pancreatic cancer is still dismal and the 5-year survival rate is only about 10%. Further improving the diagnosis and treatment of pancreatic cancer is the top priority of oncology research and clinical practice. Based on past clinical and scientific research experience, the authors have proposed ten hot spots and future directions for a reference, which focusing on early prevention, early diagnosis, and early treatment of pancreatic cancer, molecular typing and precise treatment, new drug development and regimen combination, surgical technology and strategy change, model establishment and database development, as well as innovation of traditional Chinese medicine and breakthrough of treatment concept. A breakthrough in the diagnosis and treatment of pancreatic cancer in the next ten years is raising hope, when doctors can truly prevent and control pancreatic cancer.

Guidelines for the diagnosis and treatment of pancreatic cancer in China(2021) / 中华外科杂志

The incidence of pancreatic cancer has been rising worldwide,while its clinical diagnosis and treatment remain a great challenge. To present the update and improvements in the clinical diagnosis and treatment of pancreatic cancer in recent years, Chinese Pancreatic Surgery Association,Chinese Society of Surgery,Chinese Medical Association updated "Guidelines for the diagnosis and treatment of pancreatic cancer in China （2021）" based on the Guideline of Management of Pancreatic Cancer in China which had been published in 2014. This updated guideline was formulated after reviewing evidence-based and problem-oriented literatures published from 2015-2021,mainly focusing on highlight issues regarding diagnosis and surgical treatment of pancreatic cancer,conversion strategies for locally advanced pancreatic cancer,treatment of pancreatic cancer with oligo metastasis,adjuvant and neoadjuvant therapy,standardized processing of surgical specimens and evaluation of surgical margin status,systemic treatment for unresectable pancreatic cancer,genetic testing,as well as postoperative follow up of patients with pancreatic cancer. Forty recommendation items were finally proposed based on the above issues,and the quality of evidence and strength of recommendations were graded using the Grades of Recommendation,Assessment,Development,and Evaluation system. This guideline aims to improve the ability of clinical diagnosis and therapy,especially surgical treatment of pancreatic cancer in China,and furtherly improve the prognosis of pancreatic cancer patients.

Comprehensive guidelines for the diagnosis and treatment of pancreatic cancer (2020 version) / 中华外科杂志

The incidence of pancreatic cancer has increased in recent years, and the mortality has ranked the third among malignant tumors. Advances have been made in the diagnosis and treatment of pancreatic cancer in the past decade, however, the current situation is still severe due to the uneven medical level in different regions of China. In 2018, Pancreatic Cancer Committee of Chinese Anti-cancer Association formulated the "Chinese comprehensive guidelines for the diagnosis and treatment of pancreatic cancer (2018 version)", with the view for standardizing and improving the level of diagnosis and treatment of pancreatic cancer in China. In 2020, the committee worked out the latest version of "Chinese comprehensive guidelines for the diagnosis and treatment of pancreatic cancer (2020 version)", based on the development in the past two years. These updates were mainly reflected in the following aspects: breakthroughs in targeted therapy and immunotherapy, and genetic screening and genetic sequencing has been firstly applied in the comprehensive diagnosis and treatment of pancreatic cancer. The practicability and accuracy of the 8th edition of AJCC-TNM staging system for pancreatic cancer has been validated in multi-center of China and has been used in clinical practice. Preoperative neoadjuvant therapy has become the standard treatment for borderline resectable and locally advanced pancreatic cancer, and it is gradually applied to the resectable pancreatic cancer. The surgical exploration after neoadjuvant therapy is particularly important. Chemotherapy-based systemic treatment modality, including targeted therapy and immunotherapy, has been carried out in clinical trial setting, and the benefits of maintenance therapy have been confirmed in advanced pancreatic cancer. The multi-disciplinary and multi-regional collaborative diagnosis and treatment pattern is widely popularized in China and runs through the entire diagnosis and treatment process. The development of domestic clinical trials and multi-center, cross-regional cooperation provides high-level evidence of evidence-based medicine for the new drug development and regimen optimization of pancreatic cancer. By incorporating the above latest advances into the new guideline, we aim to provide further guidance for the comprehensive diagnosis and treatment of pancreatic cancer in China.

Difficultés diagnostiques et modalités thérapeutiques d'une rupture canalaire traumatique isolée du pancréas

Introduction : Les traumatismes du pancréas sont plus fréquents. Ils rentrent souvent dans un contexte de polytraumatisme, les traumatismes isolés étant beaucoup plus rares. La présentation clinique est variée, à l'origine de retard de consultation. La tomodensitométrie abdominale reste l'examen diagnostique de référence. La chirurgie intègre l'arsenal thérapeutique avec de nombreuses options. Les auteurs se proposent de rapporter ce cas opéré au CHU de Libreville afin de relever les difficultés diagnostiques et les modalités thérapeutiques de cette entité rare. Observation : Mr SM, 37 ans, consultait pour un traumatisme abdominal post-rixe. L'examen physique notait un état de choc, une sensibilité diffuse abdominale, sans défense ni contracture. La TDM abdominale objectivait un hématome rétro-péritonéal et un épanchement péritonéal associé. L'amylasémie était à 660 UI/mL, associée à une anémie normochrome normocytaire à 9 g/dL. L'exploration chirurgicale révélait un hématome de la tête du pancréas et du deuxième duodénum. L'évacuation de l'hématome avec pose d'un drain étaient réalisés. Les suites post-opératoires étaient compliquées d'une fistule pancréatique abondante. La seconde laparotomie objectivait une fistule pancréatique avec rupture canalaire à la jonction tête-corps. Une duodéno-pancréatectomie céphalique selon Whipple était réalisée. Le patient décédait à J3 post-opératoire. Conclusion : Les traumatismes pancréatiques isolés sont rares. Leur gravité est matérialisée par l'atteinte canalaire. Le diagnostic repose sur la TDM abdominale qui doit être est systématique en cas de traumatisme abdominal et la CPRE. La DPC est une option chirurgicale avec des complications lourdes

Pancreatic cancer is a malignancy of great impact in developed countries and is having an increasing impact in Latin America. Incidence and mortality rates are similar for this cancer. This is an important reason to offer to the patients the best treatments available. During the Latin American Symposium of Gastroenterology Oncology (SLAGO) held in Viña del Mar, Chile, in April 2015, a multidisciplinary group of specialists in the field met to discuss about this disease. The main conclusions of this meeting, where practitioners from most of Latin American countries participated, are listed in this consensus that seek to serve as a guide for better decision making for patients with pancreatic cancer in Latin America.

Hepaticogastrostomia ou coledocoduodenostomia ecoguiadas em pacientes com obstrução maligna da via biliar distal / Hepaticogsatrostomy or Choledochoduodenostomy to distal malignant biliary obstruction

Introdução: O acesso biliar ecoguiado é um método de drenagem alternativo à drenagem percutânea transhepática (DPTH) e à cirurgia em pacientes com obstrução biliar distal incurável que falharam drenagem por Colangiopancreatografia Endoscópica Retrógrada (CPRE). Nos casos em que a drenagem ecoguiada anterógrada transpapilar (ou transanastomótica) e o rendez-vous ecoguiado não podem ser realizados como primeira opção, a coledocoduodenostomia (CDT) e a hepaticogastrostomia (HPG) ainda podem ser realizadas em pacientes selecionados. Estas duas vias de drenagem não anatômicas criam uma fístula entra a via biliar e o estômago ou duodeno. Não há dados na literatura que determinem superioridade de uma ou outra técnica. Objetivo: Comparar o sucesso técnico, sucesso clínico e fatores associados entre as duas vias de drenagem em pacientes com obstrução da via biliar distal maligna incurável que não lograram sucesso na drenagem por CPRE ou rendez-vous ecoguiado. Métodos: Entre abril de 2010 e dezembro de 2013, 49 pacientes com obstrução biliar distal maligna incurável que falharam CPRE e rendez-vous ecoguiado foram randomizados para CDT ou HPG. Dados referentes ao sucesso técnico, sucesso clínico, tempo de procedimento, complicações, qualidade de vida e sobrevida foram coletados até três meses após o procedimento. Todos os procedimentos foram realizados em um centro terciário de endoscopia pelo mesmo endoscopista. Próteses biliares parcialmente recobertas (Boston Scientific, Wallflex, 10 mm, 8 cm ou 6 cm) foram utilizadas em todos os pacientes com sucesso técnico. Nos casos de HPG a punção ecoguiada foi intra-hepática no ducto hepático esquerdo. Nos casos de CDT a punção foi extra-hepática no segmento distal não obstruído do colédoco. Após a punção foi realizada colangiografia com introdução de um fio guia hidrofílico de 0,035 polegada. Dilatação com cateter e um dispositivo de needle knife foi realizada para permitir introdução do sistema de disparo da prótese biliar...

Background: EUS-guided biliary access is an alternative for percutaneous access or surgery in patients with malignant unresectable distal biliary obstruction and failed ERCP. When rendezvous or anterograde transpapillary/transanastomotic intervention fails as primary drainage options, a Choledochoduodenostomy (CDT) or a Hepaticogastrostomy (HGT) can still be performed in selected patients. This procedure creates a new " " y I w one route or the other should be recommended. Aim: To compare technical and clinical success and possible associated factors between the two different drainage routes CDT and HGT in patients with distal unresectable malignant biliary obstruction that failed standard ERCP and EUS-guided rendez vouz (RV) maneuver. Methods: Between April/2010 and December/2013 49 consecutive jaundiced patients with distal unresectable malignant biliary obstruction that failed previous ERCP and EUS-guided RV maneuver were elected randomly to undergo either EUS-guided CDT or HGT. Data including indications, clinical and technical success, procedural times and complications with a three-month follow-up were prospectively collected in a database. All procedures were performed in a tertiary center by the same endoscopist. A partially covered SEMS (Boston Scientific, Wallflex, 10 mm, 8 cm or 6 cm) was used in all technically successful procedures. After puncture of left hepatic duct in case of HGT or the distal unobstructed segment of common bile duct in case of CDT a cholangiogram was obtained followed by advancement of a 0,035-inch guide wire into the biliary system. Bougies and wire-guided needle-knife were used to perform track dilation to allow passage of an 8.5 Fr stent delivery system. Results: Forty-nine cases (25 HGT and 24 CDT) were performed. All patients had intra and extra hepatic biliary dilation. Technical success rate was 96 % for HGT and 91% for CDT (p = 0.609). Clinical success rate was 91% for HPG and 77% for CDT (p = 0.234)...

Role of neoadjuvant concurrent chemoradiation in locally advanced unresectable pancreatic cancer: A feasibility study at tertiary care centre.

BACKGROUND: Pancreatic cancer has an extremely poor prognosis and prolonged survival is achieved only by resection with macroscopic tumor clearance. There is a strong rationale for a neoadjuvant approach, since a relevant percentage of pancreatic cancer patients present with non‑metastatic but locally advanced disease. The objective of the present study was to assess the effect of neoadjuvant chemoradiation therapy (NACRT) on tumor response, down staging and resection, toxicity and any survival advantage. MATERIALS AND METHODS: A prospective pilot study was carried out from January 2009 to June 2011 in which 15 patients of locally advanced unresectable pancreatic cancer were included. All patients were treated with NACRT protocol with oral Capecitabine and 3D conformal radiotherapy (3DCRT) of 30 Gy in 10 fractions. The patients were restaged 3 to 4 weeks after the completion of NACRT and explored for resection. RESULTS: Out of 15 patients, fourteen were evaluable. Four patients underwent surgery, 5 had partial response but remained unresectable, 2 patients had stable disease and 3 had progressive disease. Most of the toxicities were slight and were in grade 1 to 2. None of the patients developed grade 3 or 4 gastrointestinal or hematological toxicity. The median survival was 15 months for resected patients and 8.6 months for unresected patients, respectively. The 2 year actuarial overall survival was 34.6%. CONCLUSION: All patients with locally unresectable pancreatic cancer should be offered chemoradiation therapy, in hopes of down staging the tumor for possible resection and achieving higher survival.

Factors Affecting Tumor Ablation during High Intensity Focused Ultrasound Treatment

BACKGROUND/AIMS: High intensity focused ultrasound (HIFU) utilizes a targeted extracorporeal focused ultrasound beam to ablate neoplastic pancreatic tissue. We used an in vitro model to examine the effects of bone, metallic stents, plastic stents, metal plates, and cyst-like lesions on HIFU treatment. METHODS: HIFU was delivered to the phantom models implanted with foreign bodies, and the location, shape, and size of the ablated zones were evaluated. RESULTS: Bone and metallic plates reflected the ultrasound beam, shifting the ablation zone from the focal zone to the prefocal area. In the phantoms containing metal stent, plastic stent, and cyst, most of the ablative energy was reflected to the prefocal area by the surface, with the remainder penetrating through the phantom. The area of the ablated margins was significantly larger in size and volume than the intended focal ablation zone. CONCLUSIONS: During HIFU therapy, artificial or anatomical barriers could affect the direction of the ultrasound beams, shifting the ablation zone from the focal area to a prefocal site with a larger than expected ablation zone. These factors should be considered prior to HIFU treatment for pancreatic tumors because they could limit ablation success, in addition to causing complications.

Corte con argón plasma de prótesis autoexpansibles de nitinol: serie de 7 casos / [Trimming with argon plasma of self-expanding metal stents: report of 7 cases].

The use of self-expandable enteral stents for palliation of malignant stenosis may present the complication of concealing the ampulla of Vater behind the metallic mesh. Anchoring in the duodenal wall (distal or partial migration) may also be a complication of biliary metallic stents and therefore may cause difficulty in gaining access to the biliary tract. In these cases of difficult access, a fenestration on the prosthesis ( biliary or enteral) can be created to allow reaching the obstructed biliary tract by means of argon plasma (AP). Were retrospectively analysed 7 cases. Under endoscopic vision, AP was directed to filgurate and cut 6 biliary prosthesis and a duodenal stent. Fulguration and cut of biliary stent was performed in 5 cases of distal partial migration and cholangitis. In one case of obstruction caused by distal migration inside the duodenal stent light, cutting of the biliary stent was performed. A window was created in the enteral prosthesis in order to access the ampulla of Vater and place a biliary tract prosthesis. All cases were resolved successfully and without complications. We conclude that the use of AP to fulgurate and cut nitinol prosthesis was effective and presented no complications in this series.

A differential diagnosis of inherited endocrine tumors and their tumor counterparts

Inherited endocrine tumors have been increasingly recognized in clinical practice, although some difficulties still exist in differentiating these conditions from their sporadic endocrine tumor counterparts. Here, we list the 12 main topics that could add helpful information and clues for performing an early differential diagnosis to distinguish between these conditions. The early diagnosis of patients with inherited endocrine tumors may be performed either clinically or by mutation analysis in at-risk individuals. Early detection usually has a large impact in tumor management, allowing preventive clinical or surgical therapy in most cases. Advice for the clinical and surgical management of inherited endocrine tumors is also discussed. In addition, recent clinical and genetic advances for 17 different forms of inherited endocrine tumors are briefly reviewed.

Cistoadenoma Seroso Microquistico Multifocal de páncreas: reporte de un caso / Multifocal microcystic serous cystadenoma of the pancreas: case report

Presentamos el caso de una paciente cuyo diagnóstico anatomo-patológico fue Cistoadenoma seroso micro-quístico multifocal de páncreas, realizamos una revisión de las alternativas diagnósticas y las diferentes propuestas terapéuticas de este infrecuente tumor pancreático.

Manejo actual del cáncer de páncreas / Current management of pancreatic cancer

El cáncer de páncreas (CP) representa la cuarta causa de muerte por cáncer en países occidentales. En las últimas décadas se han obtenido múlti- ples avances respecto del entendimiento de la biología tumoral, así como en el diagnóstico, tratamiento y paliación del CP; esto demuestra que el abordaje multidisciplinario de dicha patología es esencial. La cirugía representa la mejor opción terapéutica para aquellos pacientes con enferme- dad localizada. Lamentablemente, más del 85% de ellos son diagnosticados cuando el CP se encuentra en estadios avanzados de la enfermedad. El tratamiento adyuvante, especialmente la quimioterapia, ha mejorado significativamente la supervivencia de los pacientes con CP.

Actualización diagnóstica y terapéutica de los tumores neuroendocrinos bien diferenciados / Updates on well-differentiated neuroendocrine tumors

Los tumores neuroendocrinos bien diferenciados (TNE) son neoplasias malignas poco frecuentes que incluyen tanto los carcinoides como los tumores neuroendocrinos pancreáticos (TNEP). Estos tumores se asocian en general con metástasis en el momento del diagnóstico. Si bien la supervivencia prolongada es frecuente, la supervivencia global se reduce de manera acentuada cuando los pacientes presentan síntomas, así como cuando el tumor progresa pese a la terapia con análogos de la somatostatina. Aunque estos fármacos pueden contribuir a tratar la sintomatología y ralentizar el crecimiento tumoral, en especial en neoplasias de bajo grado, no se ha demostrado que el tratamiento a largo plazo sea eficaz en estos pacientes. Recientemente, los ensayos preclínicos y dos estudios de fase III han brindado avances promisorios, sobre todo en el tratamiento de los TNEP. La aparición de terapias dirigidas contra el factor de crecimiento vascular endotelial (VEGF), los inhibidores de la diana de la rapamicina (mTOR) y el tratamiento con receptores de péptidos radiomarcados se ha asociado con eficacia moderada, pero pueden vincularse con toxicidad relevante. En esta revisión, discutiremos los ensayos recientes y las terapias actuales de los TNE bien diferenciados.

Tumores neuroendocrinos del páncreas / Pancreatic neuroendocrine tumors

Pancreatic neuroendocrine tumors are infrequent and slow-growing neoplasms. They are classified basedon their clinical presentation as functioning and nonfunctioning tumors. The most common functionaltumors are the insulinoma and gastrinoma. They can be sporadic or be part of hereditary forms as MEN-1.The diagnosis is based on the detection of the specific clinical syndrome in association of high levels of the substance secreted by the tumor and conventional imaging studies or others such as stimulation tests, somatostatin receptor scintigraphy and endoscopic ultrasound. In general, these tumors have a better prognosis than the pancreatic adenocarcinoma and they can show metastasis to the liver and infrequently, in bones. The treatment can be managed medically diminishing the inappropriate secretion of the substances by the tumor using, for example, the somatostatin analogs. Surgery should be always considered, especially in case of insulinomas, small non-functioning tumors, and small gastrinomas that can be managed with surgery enucleation. More advanced resective surgery, such as Whipple resection, are not routinely recommended and they should be limited to selected patients. In advanced tumors, there are other treatment alternatives, for example, hepatic resection, radiofrequency, chemotherapy and new agents such as sunitinib and everolimus.

Los tumores neuroendocrinos pancreáticos son infrecuentes y de crecimiento lento. Se clasifican en tumores funcionantes o no funcionantes (TNEP-NF), de acuerdo a la presentación clínica. Los tumores funcionantes más frecuentes son los insulinomas y los gastrinomas. Pueden ocurrir en forma esporádica o asociados a síndromes hereditarios como la NEM- 1, entre otros. El diagnóstico se basa en la detección del síndrome clínico específico asociado a la demostración de niveles elevados de la sustancia secretada y exámenes imagenológicos convencionales u otros más específicos como de estimulación, cintigrafía de receptores de somatostatina y endosonografía. En general, tienen mejor pronóstico que los adenocarcinomas pancreáticos y pueden dar metástasis hepáticas y con menor frecuencia, óseas. El tratamiento puede ser médico disminuyendo la secreción inapropiada de las sustancias producidas por el tumor como los análogos de somatostatina. La cirugía siempre debe ser considerada, especialmente en caso de insulinomas, pequeños TNEP-NF, y gastrinomas pequeños, que pueden ser tratados con enucleación quirúrgica. Las cirugías resectivas más avanzadas, como la operación de Whipple no están recomendadas en forma rutinaria y sólo deben ser utilizadas en pacientes seleccionados. En casos de tumores avanzados, existen alternativas de tratamiento, como la resección hepática, radiofrecuencia, quimioterapia, y terapia con nuevos agentes en estudio como el sunitinib y everolimus.
