Performance of a Multidisciplinary Pancreatic Cancer Conference in Predicting and Managing Resectable Pancreatic Cancer

Influence of endocrine multidisciplinary tumor board on patient management and treatment decision making

BACKGROUND

Multidisciplinary Tumor Boards (MDT) are used to obtain input regarding cancer management. This study assessed the impact of our institutional Endocrine MDT.

METHODS

MDT notes on patients with thyroid cancer treated during 2012-2018 were abstracted retrospectively from the electronic medical record. Management change (MC) was prospectively collected by the MDT coordinator. Biannual evaluations reviewed the impact of the MDT as observed by attendees.

RESULTS

MC was recommended in 47 (15%) of 286 presentations, with additional imaging being the most frequent (43%). Presentation of recurrences were more likely to result in MC (24% vs. 13% initial, p = 0.03). Overall, 98% of attendees found the conference exceeded educational expectations. About 24% reported intending to use a more evidence/guideline-based approach after attending and this trend increased over time (p = 0.002).

CONCLUSION

MDT presentations led to a higher rate of MC particularly in recurrent TC patients and increased evidenced-based practice for attendees.

Survival Trends for Resectable Pancreatic Cancer Using a Multidisciplinary Conference: the Impact of Post-operative Chemotherapy

PURPOSE

Despite advances in various treatment modalities, surgical resection for pancreatic ductal adenocarcinoma (PDA) remains the only curative treatment. Data remains limited regarding survival rates for resectable PDA when managed by a multidisciplinary pancreas conference (MDPC). The aim of this study is to assess survival rates, identify significant predictors of mortality, and assess the benefits of adjuvant chemotherapy for resectable PDA following presentation at a MDPC.

METHODS

All patients presented from April 2013 to August 2016 with resectable PDA were discussed at a MDPC at a tertiary care center and were followed prospectively until November 2017. Survival analysis was performed using Kaplan-Meier for age, tumor size, tumor differentiation, T-stage, lymph node status, and completion of adjuvant chemotherapy cycles. Independent predictors of survival were determined using multivariate Cox regression modeling.

RESULTS

After MDPC consensus and exclusions, total of 64 patients underwent successful surgery. Amongst this cohort, 1-, 2-, and 3-year survival was 78.13%, 46.30%, and 27.27%, respectively. A total of 37 patients (58%) initiated and 16 patients (25%) finished chemotherapy following surgery. Log-rank analysis revealed that tumor size, age, surgical margins, lymph node status, and number of adjuvant chemotherapy cycles received significantly influenced post-operative survival. Tumor size (p < 0.001), lymph node status (p = 0.035), and number of adjuvant chemotherapy cycles (p = 0.041) remained significant after multivariate Cox regression model.

CONCLUSIONS

Our results suggest that patients with PDA with tumor size > 50 mm and/or lymph node involvement have poor outcomes despite being surgically resectable. Successful completion of adjuvant chemotherapy has better survival outcomes as compared with incomplete or no adjuvant chemotherapy. The role of alternative management such as down-staging with neoadjuvant therapy should be considered.

Impact of multidisciplinary approach and radiologic review on surgical outcome and overall survival of patients with pancreatic cancer: a retrospective cohort study

AIM

To evaluate the impact of multidisciplinary team case discussion including computed tomography (CT) radiologic review on surgical outcome and overall survival (OS) of patients with pancreatic ductal adenocarcinoma (PDAC).

METHODS

Patients with PDAC evaluated in 2008-2011 and 2013-2016 (before and after multidisciplinary team introduction), aged <85 years and staged I-III, were included. Surgical failures and 2-year OS were compared in these periods. Available CT scans of preintervention period (2008-2011) cases were reviewed by two radiologists in consensus, assigning a resectability judgment to evaluate in how many cases a different recommendation would be achieved.

RESULTS

A total of 316 patients (49.3% female, age 71±10 years) were included: 132 in 2008-2011 and 184 in 2013-2016. The proportion of patients who underwent upfront surgery was similar in the two periods (51% vs 47% in 2008-2011 vs 2013-2016). Neoadjuvant referral increased from 7% to 21% and surgical resection was excluded for 42% patients in 2008-2011 vs 33% in 2013-2016 (p = 0.002). Adjusting by age, sex, and stage, surgical failures slightly decreased in 2013-2016 (odds ratio 0.89, 95% confidence interval 0.53-1.51); the decrease was stronger when therapeutic choice complied with CT indications (odds ratio 0.76, 95% confidence interval 0.36-1.63); in both cases, the decrease could be due to chance. After correction for age, sex, and stage, the hazard ratio of 2013-2016 for OS was 0.83 (95% confidence interval 0.64-1.09). In 33/114 (29%) patients, CT retrospective review produced a change in resectability judgment.

CONCLUSION

Although differences could be due to chance or generic improvement, the consistency between process and outcome indicators suggests that multidisciplinary team approach with radiologic review may improve outcomes.

Depression Before and After a Diagnosis of Pancreatic Cancer: Results From a National, Population-Based Study

OBJECTIVES

The aim of this study was to evaluate depression in pancreatic cancer (PC) patients before and after a cancer diagnosis using a US-based healthcare database. We also sought to study the impact of treatment of depression in PC patients on all-cause mortality.

METHODS

Pancreatic cancer patients with comorbid depression in Explorys (1999-2019) were compared with controls using odds ratios with 95% confidence intervals. Rates of depression diagnosed within 6 months, 1 year, and 3 years before and after a PC diagnosis were recorded. Patients who developed depression after a PC diagnosis were further categorized into those treated for depression using mental health professionals (MHPs), pharmacologic treatment, or both (2015-2019).

RESULTS

Of the 62,450 PC patients, 10,220 (16.4%) were diagnosed with depression before PC and 8130 (13%) were diagnosed with depression after PC. Patients diagnosed with depression after PC had a significantly higher all-cause mortality than patients with PC alone (P < 0.0001). Involvement of MHP significantly improved all-cause mortality (P = 0.0041).

CONCLUSIONS

Most post-PC depression is diagnosed in the first 6 months after a PC diagnosis. Although depression significantly increases PC mortality, integrating MHP in the care of PC patients with depression improves outcomes.

Value of multidisciplinary collaboration in acute and chronic pancreatitis

Multidisciplinary collaboration (MDC) has been widely adopted in healthcare to optimize patient care. MDC brings several specialized healthcare providers to the table using several methods, including multidisciplinary meetings (MDMs), multidisciplinary clinics, teleconferences, and online multidisciplinary expert panels, to reach the goal of achieving the best diagnosis and treatment plan for complex diseases. Diagnosis and management of acute/chronic pancreatitis is complex which necessitates the development and utilization of MDC. The key members of pancreatitis MDM include gastroenterologists, radiologists, pathologists, hepatobiliary surgeons, chairperson, and a coordinator. After selection of admitted or referred patients, the availability of required information is reviewed, and then each case is discussed. The final diagnosis and treatment plan is confirmed by consensus, especially for complex cases that require endoscopic intervention or pancreatectomy and patients with the possibility of pancreatic adenocarcinoma. It has been shown that MDMs have improved the clinical outcome of patients with acute/chronic pancreatitis. In addition to MDM, the feasibility of multidisciplinary clinics, teleconferences, and online multidisciplinary expert panels for the management of pancreatic disorders has been investigated. Understanding structure, potential advantages, and limitations of MDC will help clinicians and healthcare systems in developing an optimized MDC to improve the management of acute/chronic pancreatitis. This narrative review summarized prior recommendations and explored the impact of MDC on clinical outcomes of patients with pancreatitis. Our recommendations offer a generalizable method that can be utilized by healthcare systems.
