Endoscopic Palliation of Pancreatic Cancer

Role of Endoscopic Ultrasound in the Management of Pancreatic Cancer

Pancreatic cancer is one of the common causes of cancer-associated mortality with a dismal overall prognosis which has remained virtually unchanged over decades. In the present era, the management of patients with pancreatic cancer involves a multi-disciplinary team of radiologists, gastroenterologists, surgical oncologists, medical oncologists, radiation oncologists and other specialists. The advancement of interventional endoscopy has made a significant impact in the management of pancreatic cancers. Since the inception of endoscopic ultrasound, it has evolved over the last few decades in the management of pancreatic malignancies and its role in staging and tissue acquisition is well established. There is an emerging role of endoscopic ultrasound in the treatment and palliation of unresectable pancreatic cancer. The aim of this article is to review the role of endoscopic ultrasound in diagnostic and therapeutic interventions in the current era.

Appropriateness of Mini-Invasive Approaches for Nausea and Vomiting Refractory to Medical Therapy in Palliative Care Setting: A Case Report

Introduction

Nausea and vomiting are frequent multifactorial symptoms in oncological patients. These manifestations, mainly affecting the advanced disease stages, may lead to existential, psychological, and physical suffering, with a negative impact on the quality of life (QoL) of the individual and his family. The medical approach makes use of a wide range of drugs, with different antiemetic potency and various mechanisms of action, taking into account the etiology and the patient's response to the different therapeutic strategies. In recent years, in addition to pharmacological treatments, some endoscopic procedures have been integrated into clinical practice as promising palliative approaches.

Case Presentation

Herein, we describe and discuss a case of a 64-year-old female affected by advanced stage pancreatic adenocarcinoma, in which different techniques - both medical and endoscopic - have been used to approach a refractory symptomatology with a negative impact on the patient's QoL. In the context of a multidisciplinary approach in primary palliative care, a tailored intervention encompassing invasive methods for palliative purposes, may be considered adequate and appropriate when the prognostic expectation and the physical functionality indices allow it.

Conclusion

Minimally invasive palliative interventions should be offered to patients with advanced cancer when symptoms become refractory to standard medical therapies, as part of the holistic approach in modern treatments. Therefore, the integration of an early palliative approach into the patient's therapeutic path becomes essential for the management of all the individual's needs.

Endoscopic ultrasound (EUS) and the management of pancreatic cancer

Pancreatic cancer is one of the leading causes of cancer-related mortality in western countries. Early diagnosis of pancreatic cancers plays a key role in the management by identification of patients who are surgical candidates. The advancement in the radiological imaging and interventional endoscopy (including endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreatography and endoscopic enteral stenting techniques) has a significant impact in the diagnostic evaluation, staging and treatment of pancreatic cancer. The multidisciplinary involvement of radiology, gastroenterology, medical oncology and surgical oncology is central to the management of patients with pancreatic cancers. This review aims to highlight the diagnostic and therapeutic role of EUS in the management of patients with pancreatic malignancy, especially pancreatic ductal adenocarcinoma.

Endoscopic retrograde cholangiopancreatography guided interventions in the management of pancreatic cancer

Pancreatic cancer is the leading cause of cancer-related morbidity and mortality with an overall five-year survival of less than 9% in the United States. At presentation, the majority of patients have painless jaundice, pruritis, and malaise, a triad that develops secondary to obstruction, which often occurs late in the course of the disease process. The technical advancements in radiological imaging and endoscopic interventions have played a crucial role in the diagnosis, staging, and management of patients with pancreatic cancer. Endoscopic retrograde cholangiopancreatography (ERCP)-guided diagnosis (with brush cytology, serial pancreatic juice aspiration cytologic examination technique, or biliary biopsy) and therapeutic interventions such as pancreatobiliary decompression, intraductal and relief of gastric outlet obstruction play a pivotal role in the management of advanced pancreatic cancer and are increasingly used due to improved morbidity and complication rates compared to surgical management. In this review, we highlight various ERCP-guided diagnostic and therapeutic interventions for the management of pancreatic cancer.

The role of seed implantation in patients with unresectable pancreatic carcinoma after relief of obstructive jaundice using ERCP

PURPOSE

The purpose of the study was to investigate the role of iodine-125 seed implantation, guided by endoscopic ultrasound (EUS) and/or percutanous ultrasound, in patients with unresectable pancreatic carcinoma after relief of obstructive jaundice using endoscopic retrograde cholangiopancreatography (ERCP).

METHODS AND MATERIALS

A total of 101 patients with obstructive jaundice due to unresectable pancreatic carcinoma were enrolled between January 2010 and December 2017 in this retrospective study. Of these patients, 50 underwent implantation of iodine-125 seeds under EUS and/or percutaneous ultrasound guidance after receiving a stent via ERCP (treatment group), and 51 received a stent via ERCP without undergoing seed implantation (control group). The clinical data and therapeutic outcomes of these patients were analyzed.

RESULTS

Compared with the control group, the treatment group obtained significant relief of abdominal pain at the 1-week, 1-month, and 3-month followup (p < 0.05), with a significantly lower visual analog scale pain score (p < 0.05). The treatment group obtained a longer median survival (8.8 vs. 6.5 months, p = 0.02), longer median duration of stent patency (10.8 ± 1.4 vs. 6.9 ± 0.8 months, p = 0.02), and prolonged average time to gastric outlet obstruction (6.8 ± 1.6 vs. 5.3 ± 1.3 months, p = 0.02). Differences between liver function and appetite for the two groups were not significant (p > 0.05 and p = 0.59, respectively).

CONCLUSIONS

Iodine-125 seed implantation after relief of obstructive jaundice via ERCP prolongs survival, biliary stent patency, and time to gastric outlet obstruction and improves patient quality of life by relieving pancreatic pain in patients with unresectable pancreatic carcinoma.

Effect of Early Management on Pain and Depression in Patients with Pancreatobiliary Cancer: A Randomized Clinical Trial

Background: The present study assessed whether early palliative care (EPC) targeting pain and depression and automated symptom monitoring could improve symptoms in patients with advanced pancreatobiliary cancer. Methods: Patients diagnosed with pathologically confirmed locally advanced or metastatic pancreatic or biliary tract cancer who had cancer-related pain (brief pain inventory (BPI) worst pain score >3) and/or depression (Center for Epidemiological Studies-Depression Scale (CES-D) >16) were randomized within 8 weeks after diagnosis to receive EPC or on-demand palliative care (n = 144 each). EPC included (1) nursing assessment of pain and depression, (2) pain control based on National Comprehensive Cancer Network guidelines, (3) depression control by psychoeducation and/or consultation with a psychiatric specialist, and (4) patient education. The primary end points were ≥50% reductions from baseline to week 4 in pain and depression scores. Results: The proportion of patients in the EPC and usual care groups with ≥50% reductions in pain (29.5% vs. 25.2%; p = 0.4194) and depression (30.8% vs. 36.8%; p = 0.5732) scores from baseline to week 4 did not differ significantly. The proportion of patients with BPI worst pain score ≤3 was significantly higher (51.1% vs. 38.9%, p = 0.0404) and the reduction in pain intensity score significantly greater (1.5 vs. 1.0 points, p = 0.0318) in the EPC than in the usual care group. At 4 weeks, patients in the EPC group reported significant increases in global health status, role of functioning, nausea and vomiting, and pain scores on the European Organization for Research and Treatment of Cancer Core Quality of Life questionnaire (EORTC QLQ-C30) general questionnaire. Conclusions: Although the primary outcome was not met, this trial indicates that EPC may improve early pain relief in patients with advanced pancreatobiliary cancers.

Pain in pancreatic ductal adenocarcinoma: A multidisciplinary, International guideline for optimized management

Abdominal pain is an important symptom in most patients with pancreatic ductal adenocarcinoma (PDAC). Adequate control of pain is often unsatisfactory due to limited treatment options and significant variation in local practice, emphasizing the need for a multidisciplinary approach. This review contends that improvement in the management of PDAC pain will result from a synthesis of best practice and evidence around the world in a multidisciplinary way. To improve clinical utility and evaluation, the evidence was rated according to the GRADE guidelines by a group of international experts. An algorithm is presented, which brings together all currently available treatment options. Pain is best treated early on with analgesics with most patients requiring opioids, but neurolytic procedures are often required later in the disease course. Celiac plexus neurolysis offers medium term relief in a substantial number of patients, but other procedures such as splanchnicectomy are also available. Palliative chemotherapy also provides pain relief as a collateral benefit. It is stressed that the assessment of pain must take into account the broader context of other physical and psychological symptoms. Adjunctive treatments for pain, depression and anxiety as well as radiotherapy, endoscopic therapy and neuromodulation may be required in selected patients. There are few comparative studies to help define which combination and order of these treatment options should be applied. New pain therapies are emerging and could for example target neural transmitters. However, until better methods are available, management of pain should be individualized in a multidisciplinary setting to ensure optimal care.

Alleviating Pancreatic Cancer-Associated Pain Using Endoscopic Ultrasound-Guided Neurolysis

The most common symptom in patients with advanced pancreatic cancer is abdominal pain. This has traditionally been treated with nonsteroidal anti-inflammatory drugs and opioid analgesics. However, these treatments result in inadequate pain control or drug-related adverse effects in some patients. An alternative pain-relief modality is celiac plexus neurolysis, in which the celiac plexus is chemically ablated. This procedure was performed percutaneously or intraoperatively until 1996, when endoscopic ultrasound (EUS)-guided celiac plexus neurolysis was first described. In this transgastric anterior approach, a neurolytic agent is injected around the celiac trunk under EUS guidance. The procedure gained popularity as a minimally invasive approach and is currently widely used to treat pancreatic cancer-associated pain. We focus on two relatively new techniques of EUS-guided neurolysis: EUS-guided celiac ganglia neurolysis and EUS-guided broad plexus neurolysis, which have been developed to improve efficacy. Although the techniques are safe and effective in general, some serious adverse events including ischemic and infectious complications have been reported as the procedure has gained widespread popularity. We summarize reported clinical outcomes of EUS-guided neurolysis in pancreatic cancer (from the PubMed and Embase databases) with a goal of providing information useful in developing strategies for pancreatic cancer-associated pain alleviation.
