October 2013 — 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.

Cancer Specialty Care Centers of UPMC CancerCenter Provide Streamlined and Efficient
Care Using Cutting-Edge Treatments
David Bartlett, MD — January 2013
Cancer Specialty Care Centers of UPMC CancerCenter provide a seamless, coordinated care approach that focuses on getting patients examined, tested, diagnosed or confirmed, and treated in the quickest time possible.
Specialty Care Centers are organized by disease sites and offer efficient care by a multidisciplinary team of specialists, allowing experts to offer leading cancer treatments and therapies. The centers are for patients who:
- Have advanced or rare forms of cancer.
- Have metastatic disease.
- Seek a second opinion on their diagnosis.

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.

Flexible Sigmoidoscopy Screening Reduces Colorectal Cancer Incidence and Mortality
Robert Schoen, MD, MPH — July 2012
A new study of the multicenter Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial evaluated the effect of colorectal cancer screening by flexible sigmoidoscopy in comparison with usual care. Results of this large randomized trial indicate that screening with flexible sigmoidoscopy was associated with a 26% reduction in overall colorectal cancer mortality and a 21% reduction in the incidence of colorectal cancer.
Watch Robert Schoen, MD, MPH, Professor of Medicine and Epidemiology at the University of Pittsburgh, and lead author of the study, discuss these results that were recently published in the New England Journal of Medicine.
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.

Joel Greenberger, MD — April 2012
According to a UPCI/University of Pittsburgh School of Medicine study, researchers may have a better way of understanding how a drug used to protect against and mitigate irradiation damage interacts inside human cells. The study involved the successful labeling and tracking of JP4-039, a drug that combats irradiation-induced cell death by assisting the mitochondria.
Results of the study will be presented at the AACR Annual Meeting in Chicago.
