Project description:Pancreatic ductal adenocarcinoma (PDAC) is currently ranked fourth place of cancer related mortality. Only a minority of 10-20% of patients with PDAC have a primarily resectable disease, while 50-60% of the patients are diagnosed with irresectable disease. A certain group of patients is defined as "borderline resectable", which is mainly relied to contact of the tumor to major abdominal vessels. For preoperative evaluation of resectability CT and MRI is commonly used. Although CT-scanning, which is the standard preoperative imaging modality, has striking limitations concerning evaluation of lymph node status as well as vessel involvement and approximately 20% of the patients are staged incorrectly. A central part of modern therapy of locally advanced or not primarily resectable PDAC is neoadjuvant therapy. Especially neoadjuvant chemotherapy according to the FOLFIRINOX protocol resulted in high resection rates of initially not resectable patients. Furthermore, treatment with FOLFIRINOX was shown to be an independent predictor of improved prognosis and resection after neoadjuvant treatment with FOLFIRINOX was associated with improved survival. Neoadjuvant treatment was able to increases the rates of R0 resection, which depicts an independent prognostic factor and FOLFIRINOX outmatched other treatment regimes (e.g., gemcitabine-based radio-chemotherapy) concerning achievement of a R0 resection. While most evidence of neoadjuvant treatment of PDAC is conferred by retrospective analysis, there is growing data from randomized controlled trials, confirming the beneficial effects of neoadjuvant therapy on the prognosis of PDAC. Thus, patients with borderline resectable and locally advanced PDAC should be evaluated for neoadjuvant treatment. If there is no progression of the disease during neoadjuvant treatment exploration with the goal of R0 resection should be performed. If possible, patients should be included in well-designed randomized controlled trials at specialized pancreatic centers.

Project description:The management of locally advanced rectal cancer has undergone significant transformations over the decades and optimal treatment approaches continue to evolve. There have been numerous advances in surgery, chemotherapy, and radiation therapy from the first description of the abdominoperineal resection in 1908, timing of chemotherapy and radiation therapy in the late 20th and early 21st century, and most recently, the introduction of organ preservation or nonoperative management in 2004. Alongside these advancements, the concept of shared decision making in medicine has evolved, prompting a focus on patient-centered care. This evolution in practice has been fueled by a growing recognition of the importance of patient autonomy and the alignment of treatment options with patients' values and preferences. With the growing number of possible treatment options, variability in patient counseling exists, highlighting the need for a standardized approach to shared decision making in locally advanced rectal cancer. This narrative review will describe the evolution of treatment options of locally advanced rectal cancer as well as the concept of shared decision making and decision aids, and will introduce a decision aid for patients with locally advanced rectal cancer who have achieved a complete clinical response and are eligible for watch and wait.

Project description:During decision-making, neurons in the orbitofrontal cortex (OFC) sequentially represent the value of each option in turn, but it is unclear how these dynamics are translated into a choice response. One brain region that may be implicated in this process is the anterior cingulate cortex (ACC), which strongly connects with OFC and contains many neurons that encode the choice response. We investigated how OFC value signals interacted with ACC neurons encoding the choice response by performing simultaneous high-channel count recordings from the two areas in nonhuman primates. ACC neurons encoding the choice response steadily increased their firing rate throughout the decision-making process, peaking shortly before the time of the choice response. Furthermore, the value dynamics in OFC affected ACC ramping-when OFC represented the more valuable option, ACC ramping accelerated. Because OFC tended to represent the more valuable option more frequently and for a longer duration, this interaction could explain how ACC selects the more valuable response.

Project description:BackgroundCompared to the widely adopted 2-4 months of pre-operative therapy for patients with borderline resectable (BR) or locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC), our institution tends to administer a longer duration before considering surgical resection. Using this unique approach, the aim of this study was to determine pre-operative variables associated with survival.MethodsRecords from patients with BR/LA PDAC who underwent attempt at surgical resection from 1992-2014 were reviewed.ResultsAfter a median duration of 6 months of pre-operative treatment, 109 patients with BR/LA PDAC (BR 63, LA 46) were explored; 93 (85.3 %) underwent pancreatectomy. Those who received at least 6 months of pre-operative treatment had longer median overall survival (OS) than those who received less (52.8 vs. 32.1 months, P = 0.044). On multivariate analysis, pre-operative treatment duration was the strongest predictor of survival (hazard ratio (HR) 4.79, P = 0.043). However, OS was similar in those whose CA19-9 normalized regardless of whether they received more or less than 6 months of chemotherapy (71.4 vs. 101.8 months, P = 0.930).ConclusionsPre-operative CA19-9 decline can guide treatment duration in patients with BR/LA PDAC. We endorse 6 months of therapy except in those patients whose values normalize, where surgery can be considered after a shorter course.

Project description:Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignant tumor types, being the sixth leading cause of mortality worldwide and the fourth in Europe. Globally, it has a mortality/incidence ratio of 98%, and the 5‑year survival rate in Europe is only 3%. Although risk factors, such as obesity, diabetes mellitus, smoking, alcohol consumption and genetic factors, have been identified, the causes of PDAC remain elusive. Additionally, the only curative treatment for PDAC is surgery with negative margins. However, upon diagnosis, ~30% of the patients already present with locally advanced disease. In these cases, a multidisciplinary approach is required to improve disease‑related symptoms and prolong patient survival. In the present article, a comprehensive review of PDAC epidemiology, physiology and treatment is provided. Moreover, guidelines on patient treatment are suggested. Among the different available therapeutic options for the treatment of advanced PDAC, results are modest, most likely due to the complexity of the disease, and so the prognostic remains poor. Molecular approaches based on multi‑omics research are promising and will contribute to groundbreaking personalized medicine. Thus, economic investment that promotes research of pancreatic cancer will be critical to the development of more efficient diagnostic and treatment strategies.

Project description:PurposeSolutions to improve the implementation of shared decision making (SDM) in oncology often focus on the consultation, with limited effects. In this study, we used a service design perspective on the care path of locally advanced pancreatic cancer (LAPC). We aimed to understand how experiences of patients, their significant others, and medical professionals over the entire care path accumulate to support their ability to participate in SDM.Participants and methodsWe used qualitative interviews including design research techniques with 13 patients, 13 significant others, and 11 healthcare professionals, involved in the diagnosis or treatment of LAPC. The topic list was based on the literature and an auto-ethnography of the illness trajectory by a caregiver who is also a service design researcher. We conducted a thematic content analysis to identify themes influencing the ability to participate in SDM.ResultsWe found four interconnected themes: (1) Decision making is an ongoing and unpredictable process with many decision moments, often unannounced. The unpredictability of the disease course, tumor response to treatment, and consequences of choices on the quality of life complicate decision making; (2) Division of roles, tasks, and collaboration among professionals and between professionals and patients and/or their significant others is often unclear to patients and their significant others; (3) It involves "work" for patients and their significant others to obtain and understand information; (4) In "their disease journey," patients are confronted with unexpected energy drains and energy boosts, that influence their level of empowerment to participate in SDM.ConclusionThe service design perspective uncovered how the stage for SDM is often set outside the consultation, which might explain the limited effect currently seen of interventions focusing on consultation itself. Our findings serve as a starting point for (re)designing care paths to improve the implementation of SDM in oncology.

Project description:Pancreatic cancer is the 7th leading cause of death due to cancer in industrialized countries and the 11th most common cancer globally, with 458918 new cases (2.5% of all cancers) and 432242 deaths (4.5% of all cancer deaths) in 2018. Unfortunately, 80% to 90% of the patients present with unresectable disease, and the reported 5-year survival rate range between 10% and 25%, even after successful resection with tumor-free margins. Systemic chemotherapy, radiotherapy, and minimally invasive image-guided procedures that have emerged over the past years, are used for the management of non-operable PC. This review focuses on currently available non-surgical options of locally advanced pancreatic cancer.

Project description:Background and purposeThe aim of this study was to evaluate the significance of baseline computed tomography (CT) imaging features and carbohydrate antigen 19-9 (CA19-9) in predicting prognosis of locally advanced pancreatic cancer (LAPC) receiving intraoperative radiotherapy (IORT) and to establish a progression risk nomogram that helps to identify the potential beneficiary of IORT.MethodsA total of 88 LAPC patients with IORT as their initial treatment were enrolled retrospectively. Clinical data and CT imaging features were analyzed. Cox regression analyses were performed to identify the independent risk factors for progression-free survival (PFS) and to establish a nomogram. A risk-score was calculated by the coefficients of the regression model to stratify the risk of progression.ResultsMultivariate analyses revealed that relative enhanced value in portal-venous phase (REV-PVP), peripancreatic fat infiltration, necrosis, and CA19-9 were significantly associated with PFS (all p < 0.05). The nomogram was constructed according to the above variables and showed a good performance in predicting the risk of progression with a concordance index (C-index) of 0.779. Our nomogram stratified patients with LAPC into low- and high-risk groups with distinct differences in progression after IORT (p < 0.001).ConclusionThe integrated nomogram would help clinicians to identify appropriate patients who might benefit from IORT before treatment and to adapt an individualized treatment strategy.

Project description:BackgroundQuality of life in cancer patients might be affected by chemotherapy-induced toxicity. Especially in patients with pancreatic ductal adenocarcinoma (PDAC), with a short life expectancy, fear of poor quality of life is often a reason for both patients and medical oncologists to refrain from further treatment. In this study, we investigated quality of life (QoL), pain, sleep, and activity levels in locally advanced pancreatic cancer (LAPC) patients after FOLFIRINOX treatment.MethodsA total of 41 LAPC patients with stable disease or partial response were included after completion of at least four cycles of FOLFIRINOX. QoL was measured with the EORTC QLQ-C30 and NRS pain scores. Patients completed the Richards-Campbell Sleep Questionnaire (RCSQ) for five consecutive nights and wore a GENEActiv tri-axial accelerometer (Actiwatch) for 7 days, registering sleep duration, efficiency, and activity.ResultsMean EORTC QLQ-C30 score for global health status was 78.3 (± 17.3), higher than reference values for cancer patients (P < 0.001) and general population (P = 0.045). LAPC patients reported few disease-related symptoms. Two patients (5%) reported pain scores > 3. Mean sleep duration was 8 h/night (± 1.2 h) and sleep efficiency 70% (± 9%) with high patient-reported quality of sleep (mean RCSQ score 72.0 ± 11.4). Mean duration of moderate-vigorous activity was 37 min/week (± 103 min/week).ConclusionsQoL is very good in most LAPC patients with disease control after FOLFIRINOX, measured with validated questionnaires and Actiwatch registration. The fear of clinical deterioration after FOLFIRINOX is not substantiated by this study and should not be a reason to refrain from treatment.Trial registrationDutch trial register NL7578.
