The liver is one of the most common sites for metastatic disease, and optimal management of hepatic metastases often requires a multidisciplinary approach. Most commonly, liver metastases are derived from a colorectal or neuroendocrine primary tumor. Liver resection with curative intent is standard for resectable cases, but unfortunately most patients are not initially resectable because of the size, location, and/or extent of disease; inadequate remnant liver volume; or comorbidities. For patients with liver-limited or liver-dominant colorectal liver metastases (CRLM), the current challenges are to use different locoregional treatments to convert some borderline unresectable cases to resectable, and improve local control and overall survival. Although neuroendocrine liver metastases (NELM) may behave in a relatively indolent manner from an oncologic perspective, significant morbidity may be caused by excess hormone production when compared with metastatic liver disease from other primaries, and liver-directed treatment may be beneficial in reducing symptoms and perhaps extending survival. In the multidisciplinary management of patients with liver metastases, local therapies are especially important. Local approaches may be complementary (ie, portal vein embolization) or an alternative (ie, ablation, hepatic arterial infusion, selective radioembolization, and stereotactic body radiotherapy) to surgical resection. This article evaluates the available evidence on current regional strategies for managing patients with liver metastases, with an emphasis on CRLM and NELM, highlighting the clinical usefulness and limitations of each modality.

New combinations of cytotoxic chemotherapy have been proven to increase response rates and survival times compared with single-agent gemcitabine for patients with metastatic pancreatic cancer. These responses have been dramatic for a subset of patients, therefore raising questions about the management of limited metastatic disease with surgery or other ablative methods. Similarly, for patients having a complete radiographic response to chemotherapy in the metastatic compartment, whether to consider local therapy in the form of radiation or surgery for the primary tumor is now an appropriate question. Therefore, collaboration among experts in surgery, medical oncology, and radiation oncology has led to the development of guiding principles for local therapies to the primary intact pancreatic tumor for patients with limited metastatic disease and those who have had a significant response after systemic therapy.

Background: The immune system plays an important role in cancer surveillance and therapy. Chemoradiation can cause severe treatment-related lymphopenia (TRL) (<500 cells/mm3) that is associated with reduced survival. Materials and Methods: Data from 4 independent solid tumor studies on serial lymphocyte counts, prognostic factors, treatment, and survival were collected and analyzed. The data set included 297 patients with newly diagnosed malignant glioma (N=96), resected pancreatic cancer (N=53), unresectable pancreatic cancer (N=101), and non–small cell lung cancer (N=47). Results: Pretreatment lymphocyte counts were normal in 83% of the patient population, and no patient had severe baseline lymphopenia. Two months after initiating chemoradiation, 43% developed severe and persistent lymphopenia (P=.001). An increased risk for death was attributable to TRL in each cancer cohort (gliomas: hazard rate [HR], 1.8; 95% CI, 1.13–2.87; resected pancreas: HR, 2.2; 95% CI, 1.17–4.12; unresected pancreas: HR, 2.9; 95% CI, 1.53–5.42; and lung: HR, 1.7; 95% CI, 0.8–3.61) and in the entire study population regardless of pathologic findings (HR, 2.1; 95% CI, 1.54–2.78; P<.0001). Severe TRL was observed in more than 40% of patients 2 months after initiating chemoradiation, regardless of histology or chemotherapy regimen, and was independently associated with shorter survival from tumor progression. Conclusions: Increased attention and research should be focused on the cause, prevention, and reversal of this unintended consequence of cancer treatment that seems to be related to survival in patients with solid tumors.

An association between diabetes mellitus and pancreatic ductal adenocarcinoma (PDA) has long been recognized. This article assesses the effect of the baseline hemoglobin-A1c (HbA1c) value on the clinical outcomes of patients with PDA. HbA1c values were prospectively collected on 656 consecutive patients presenting to a pancreas multidisciplinary cancer clinic from 2009 to 2012. Patients were diagnosed with benign pancreatic disease (BPD) or biopsy-confirmed resectable (R), borderline/locally advanced (BL), or metastatic (M) PDA. Excluded were those with prior treatment for PDA or a history of chronic diabetes mellitus (>1-year or unknown duration), resulting in a final cohort of 284 patients. Of 284 patients, 44 had benign disease, 62 had R-PDA, 115 had BL-PDA, and 63 had M-PDA. Patients with malignant disease (R-, BL-, and M-PDA) collectively had a higher average HbA1c value than patients with BPD (6.1% vs 5.6%; P<.001). Among patients with PDA (n=240), HbA1c values of 6.5% or greater were significantly associated with inferior overall survival (OS) compared with patients with HbA1c values less than 6.5% (hazard ratio [HR], 1.74; OS, 10.2 vs 13.0 months; P=.007), along with other known prognostic factors, such as age of 65 years or older, ECOG performance status of 1 or greater, carbohydrate antigen 19-9 level greater than 90, tumor size larger than 3 cm, and disease stage. HbA1c values of 6.5% or greater remained in the final predictive model using backward elimination (HR, 1.46; P=.097), indicating that HbA1c values of 6.5% or greater influence OS of patients with PDA even when accounting for other known prognostic factors. HbA1c level at presentation is significantly higher in patients with PDA than patients with BPD and seems to affect survival.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Pancreatic Adenocarcinoma discuss the workup and management of tumors of the exocrine pancreas. These NCCN Guidelines Insights provide a summary and explanation of major changes to the 2012 NCCN Guidelines for Pancreatic Adenocarcinoma. The panel made 3 significant updates to the guidelines: 1) more detail was added regarding multiphase CT techniques for diagnosis and staging of pancreatic cancer, and pancreas protocol MRI was added as an emerging alternative to CT; 2) the use of a fluoropyrimidine plus oxaliplatin (e.g., 5-FU/leucovorin/oxaliplatin or capecitabine/oxaliplatin) was added as an acceptable chemotherapy combination for patients with advanced or metastatic disease and good performance status as a category 2B recommendation; and 3) the panel developed new recommendations concerning surgical technique and pathologic analysis and reporting.

The NCCN Guidelines for Pancreatic Adenocarcinoma discuss the diagnosis and management of adenocarcinomas of the exocrine pancreas and are intended to assist with clinical decision-making. These NCCN Guidelines Insights summarize major discussion points from the 2014 NCCN Pancreatic Adenocarcinoma Panel meeting. The panel discussion focused mainly on the management of borderline resectable and locally advanced disease. In particular, the panel discussed the definition of borderline resectable disease, role of neoadjuvant therapy in borderline disease, role of chemoradiation in locally advanced disease, and potential role of newer, more active chemotherapy regimens in both settings.

Ductal adenocarcinoma and its variants account for most pancreatic malignancies. High-quality multiphase imaging can help to preoperatively distinguish between patients eligible for resection with curative intent and those with unresectable disease. Systemic therapy is used in the neoadjuvant or adjuvant pancreatic cancer setting, as well as in the management of locally advanced unresectable and metastatic disease. Clinical trials are critical for making progress in treatment of pancreatic cancer. The NCCN Guidelines for Pancreatic Adenocarcinoma focus on diagnosis and treatment with systemic therapy, radiation therapy, and surgical resection.
