New NCI Grant Funds Collaborative Effort to Improve Early Detection of Pancreatic CancerRandall Brand, MD — June 2016
A majority of pancreatic cancer patients (>80%) present with a surgically unresectable primary tumor with distant metastasis at the time of diagnosis due to the lack of associated symptoms and lack of methods for early detection. While the overall 5-year survival rate of pancreatic cancer is low, significantly better outcomes have been reported for early stage, smaller tumors.
Supported by a newly funded grant from the National Cancer Institute (NCI), Randall Brand, MD, Professor of Medicine, Academic Director of the GI Division at UPMC Shadyside, and Director of the GI Malignancy Early Detection, Diagnosis and Prevention Program, and his colleagues both at the University of Pittsburgh and the University of Nebraska are developing novel biomarker-based blood tests that may detect pancreatic cancer earlier and distinguish between dangerous and benign pancreatic cysts. Specifically, the research team has conclusively established that overexpression of the glycoprotein mucin is a hallmark of pancreatic cancer, and has identified several biomarkers (MUC5AC and its 2 glycoforms, MUC4 and a glycoform of endorepellin) that hold promise for clinical benefit in pancreatic cancer detection and risk prediction. Watch Dr. Brand discuss these studies in the video.

Depressed Patients at Higher Risk for Complications and Hospital Readmission after Complex Cancer Surgery
Carissa Low, PhD — March 2016
Cancer patients who report significant symptoms of depression before undergoing a complex abdominal surgery are at increased risk of postoperative complications and unplanned hospital readmissions, according to a UPCI study published recently in the Journal of Clinical Oncology.
The study examined the relationship between preoperative symptoms of depression and 30-day complications and readmissions, as well as overall survival for patients undergoing hyperthermic intraperitoneal chemotherapy with cytoreductive surgery (HIPEC+CS), a complex surgical procedure during which abdominal tumors are removed and the area is "washed" with high doses of heated chemotherapy.
After statistically adjusting the findings to take into consideration possible effects of demographic and disease-specific risk factors, patients who reported significant symptoms of depression before surgery were more than five times more likely to have a complication or an unplanned hospital readmission within 30 days of hospital discharge.
Watch the study's lead author, Carissa Low, PhD, Assistant Professor of Medicine and Psychology and member of UPCI's Biobehavioral Oncology Program, discuss these findings in the video below, and read the press release here.

Dr. Thomas Kensler Named Outstanding Investigator by NCI, Awarded $6.3M for Studying How Food Can Lower Cancer Risks
Thomas Kensler, PhD — September 2015
Thomas Kensler, PhD, Professor of Pharmacology and Chemical Biology and Co-Leader of the UPCI Cancer Epidemiology and Prevention Program, was awarded a $6.3 million Outstanding Investigator Award from the National Cancer Institute (NCI). This new, 7-year award acknowledges experienced researchers and provides them with long-term support for their exceptional work.
Dr. Kensler's research focuses on chemoprevention, or how food can be used to lower the risk of developing cancer caused by unavoidable environmental toxins. Research has shown that controlling diet, increasing exercise and quitting smoking can decrease the risk of developing cancer; however, environmental toxins such as fossil fuel combustion products are more difficult to mitigate. Past studies by Dr. Kensler's team in China, where environmental controls are less rigorous, have examined the bioactive molecules in broccoli and how they may help people there detoxify air pollutants. He and his team will focus on a biological pathway known to play a role in detoxification, identify and validate biomarkers of its activity, and examine the molecular consequences of its chronic activation.

UPCI Scientists Find Patients With Invasive Lobular Carcinoma May Benefit From Personalized
Steffi Oesterreich, PhD and Matthew Sikora, PhD — March 2014
According to a multidisciplinary team led by scientists at the University of Pittsburgh Cancer Institute (UPCI), invasive lobular carcinoma (ILC), the second-most common type of breast cancer, appears to be a good candidate for a personalized approach to treatment.
Patients with ILC are typically treated with surgery and chemotherapy or hormone therapy, or both. According to Steffi Oesterreich, PhD, Professor of Pharmacology & Chemical Biology, and Director of Education at the Women's Cancer Research Center, a subset of patients with ILC receive less benefit from this treatment than those with ductal carcinoma. Dr. Oesterreich's team recently described a unique program of estrogen receptor-driven gene expression in ILC cells that may play a role in drug resistance.
These findings were recently published in the March 1 edition of Cancer Research.

Accurately Identifying Neck Tumors Using Robotics Improves Treatment, Survival
Umamaheswar Duvvuri, MD, PhD — October 2013
Researchers at the University of Pittsburgh Cancer Institute (UPCI) recently found that by using robotic surgery done through the mouth to identify the cause of lumps in the neck, physicians can better target more personalized therapies for patients and dramatically improve survival.
In the study, researchers examined 206 head and neck robotic cases performed at UPMC between December 2009 and December 2012. Transoral robotic surgery was performed on 22 patients where there was a lump in the neck with unknown origin, also known as occult primary squamous cell carcinoma. Of these 22 patients, the primary tumor was identified in 19 cases.
In order to determine the impact of identifying the unknown primary tumor on overall survival, researchers matched 69 patients with undiscovered carcinoma of unknown primary (following clinical exam, imaging, and surgical evaluation) and 67 patients in which the primary was discovered at the initial surgical evaluation. They found a difference in overall survival between undiscovered (8.83 years) and discovered (10.19 years).
UPCI researchers presented their findings at the ASTRO annual meeting in Atlanta.

First-in-Human Trial of a STAT-3 Selective Inhibitor for Cancer Therapy
Jennifer Grandis, MD, FACS — July 2012
There has been evidence that signal transducer and activator of transcription-3 (STAT-3) is increased in cancers, where it drives cell transformation, tumor progression, and resistance to therapy. While STAT-3 is therefore considered a highly attractive therapeutic target, it has long been regarded as "undruggable."
Recently published in the new AACR journal Cancer Discovery, researchers at the University of Pittsburgh and collaborators have developed a new strategy to block STAT-3 in cancers. Specifically, they developed a STAT-3 decoy oligonucleotide that effectively decreased levels of STAT-3 target genes in head and neck tumors in a phase 0 trial. Through chemical modification, the team enhanced the stability of this molecule to enable systemic delivery of the drug in patients.
Watch Jennifer Grandis, MD, FACS, Professor of Otolaryngology at the University of Pittsburgh School of Medicine, and Leader of the Head and Neck Cancer Program at UPCI, discuss the study and its results.

Chemoprevention Studies Uncover Cancer-Inhibitory Mechanisms of Dietary Constituents
Shivendra Singh, PhD — April 2012
While population-based studies have demonstrated that people who eat a diet rich in fruits and vegetables have a lower risk of developing cancer, scientists are now beginning to uncover the specific dietary components responsible and their mechanisms of action. Recently, UPCI researchers discovered that the broccoli constituent analogue D,L-sulforaphane (SFN), a promising cancer chemopreventive agent, can induce cell death through a mechanism involving PKCβ-mediated phosphorylation of the p66Shc adaptor protein. In addition, the research team demonstrated that benzyl isothiocynate (BITC), a constituent of edible cruciferous vegetables, can induce breast cancer and colon cancer cell death through a PUMA-dependent mechanism.

Genomic Analysis of Kidney Cancers Reveal Shared Tumor Type-Specific Copy
William LaFramboise, PhD and Rajiv Dhir, MD — April 2012
In a collaborative research study, investigators at UPCI characterized several diagnostic subtypes of renal cell cancers based on the distribution of copy number variants (CNV) both within and across tumors spanning the entire genome. They found that despite immense genomic heterogeneity, distinct CNV segments were common within each of 4 tumor subclassifications. The subset of shared genomic amplifications or deletions that were identified for each subclassification could provide critical diagnostic or prognostic biomarkers of renal cell cancers.
This study was recently published in the American Journal of Pathology.
