Near-Infrared Characterization Of Breast Tumors In Vivo Using Spectrally-Constrained Reconstruction, Subhadra Srinivasan, Brian W. Pogue, Ben Brooksby, Shudong Jiang, Hamid Dehghani, Christine Kogel, Wendy A. Wells, Steven P. Poplack, Keith D. Paulsen

Dartmouth Scholarship

Multi-wavelength Near-Infrared (NIR) Tomography was utilized in this study to non-invasively quantify physiological parameters of breast tumors using direct spectral reconstruction. Frequency domain NIR measurements were incorporated with a new spectrally constrained direct chromophore and scattering image reconstruction algorithm, which was validated in simulations and experimental phantoms. Images of total hemoglobin, oxygen saturation, water, and scatter parameters were obtained with higher accuracy than previously reported. Using this spectral approach, in vivo NIR images are presented and interpreted through a series of case studies (n=6 subjects) having differing abnormalities. The corresponding mammograms and ultrasound images are also evaluated. Three of six …

Lymphoepithelioma-Like Carcinoma Of Urinary Bladder: (Lelca), Nausheen Yaqoob, Naila Kayani, Jaipal Piryani, Mohammad Nasir Sulaiman, Sheema H. Hasan

Department of Pathology and Laboratory Medicine

Lymphoepithelioma-like carcinoma of the bladder (LELCA) is an uncommon neoplasm of the urinary bladder and up till now only 49 cases have been reported in the English literature. It is imperative to distinguish between lymphoepithelioma-like carcinoma and malignant lymphoma as primary bladder lymphoma is extremely rare. We report a case of a 55 year old lady who presented with the complaint of burning micturition and gross hematuria for the past 5 months. There were no other known comorbids. Pelvic ultrasound was normal. Cystoscopy showed a 4x4 cm sessile mass in the bladder. Histopathological examination was consistent with the diagnosis of …

Collecting Duct Carcinoma Of The Kidney: An Immunohistochemical Study Of 11 Cases., Andrea Vecchione, Tommaso Prayer Galetti, Marina Gardiman, Hideshi Ishii, Enrico Giarnieri, Francesco Pagano, Leonard G Gomella, Carlo M Croce, Raffaele Baffa

Department of Urology Faculty Papers

BACKGROUND: Collecting duct carcinoma (CDC) is a rare but very aggressive variant of kidney carcinoma that arises from the epithelium of Bellini's ducts, in the distal portion of the nephron. In order to gain an insight into the biology of this tumor we evaluated the expression of five genes involved in the development of renal cancer (FEZ1/LZTS1, FHIT, TP53, P27kip1, and BCL2). METHODS: We studied eleven patients who underwent radical nephrectomy for primary CDC. All patients had an adequate clinical follow-up and none of them received any systemic therapy before surgery. The expression of the five markers for tumor initiation …

Electric Field Enhanced Plasmid Delivery To Liver Hepatocellular Carcinomas, Richard Gilbert, Mark J. Jaroszeski, Loree Heller, Richard Heller

Bioelectrics Publications

Electric field enhanced molecular delivery for cancer research and treatment is a new technology that has demonstrated its effectiveness in clinical trials using bleomycin or cisplatin (Heller, R., Gilbert, R., Jaroszeski, M. J. Clinical applications of electrochemotherapy, Advanced Drug Delivery Reviews 35,119-129, 1999), as chemotherapeutic agents. The technology is being investigated in research applications for applicability as a method to enhance gene expression in a target tumor. Success is predicated on an appropriate effective electric field mediated delivery protocol that triggers significant appropriate gene expression duration and levels. An electric field mediated delivery protocol includes a set of conditions …

Nipple Aspirate Cytology And Pathologic Parameters Predict Residual Cancer And Nodal Involvement After Excisional Breast Biopsy., E R Sauter, H Ehya, A Mammen, G Klein

Department of Surgery Faculty Papers

We previously demonstrated that abnormal nipple aspirate fluid (NAF) cytology predicted residual breast cancer (RC) and tumour size after excisional biopsy (EB), although normal NAF cytology did not exclude RC. Tumour size correlates with the risk of lymph node (LN) metastases. LN metastases provide prognostic information allowing medical and radiation oncologists to determine the need for adjuvant therapy. We hypothesized that pathologic factors known after EB, combined with NAF cytology, would predict with a high degree of accuracy the presence of RC and LN spread. NAF cytology and pathologic parameters: tumour distance from biopsy margins, multifocal and multicentric disease, sub-type …

Is Mammography Useful In Screening For Local Recurrences In Patients With Tram Flap Breast Reconstruction After Mastectomy For Multifocal Dcis?, A P Salas, M A Helvie, E G Wilkins, H A Oberman, P W Possert, Alan M. Yahanda Md, Facs, A E Chang

PCI Publications and Projects

BACKGROUND: Skin-sparing mastectomy with immediate transverse rectus abdominis musculocutaneous (TRAM) flap reconstruction is being used more often for the treatment of breast cancer. Mammography is not used routinely to evaluate TRAM flaps in women who have undergone mastectomy. We have identified the potential value of its use in selected patients.

METHODS AND RESULTS: We report on four women who manifested local recurrences in TRAM flaps after initial treatment for ductal carcinoma in situ (DCIS) or DCIS with microinvasion undergoing skin-sparing mastectomy and immediate reconstruction. All four patients presented with extensive, high-grade, multifocal DCIS that precluded breast conservation. Three of four …

Detection Of Unique Tumor-Associated Proteins In The Urine Of Patients With Transitional Cell Carcinoma By High Resolution Two-Dimensional Polyacrylamide Gel Electrophoresis, Robert David Lehman

Biological Sciences Theses & Dissertations

A two-dimensional polyacrylamide gel electrophoretic technique was developed for the detection of unique tumor-associated proteins in urine of patients with transitional cell carcinoma (TCC) of the urinary bladder. This technique yielded high resolution of polypeptides in the urine of cancer patients. Urine was chosen as a source of tumor-associated components because the location of the tum or should release already solublized tum or substances in to the urine.

Urinary proteins were concentrated and then analyzed by the two - dimensional electrophoretic technique using isoelectric focusing in the first dimension and sodium dodecylsulfate - polyacrylamide gel electrophoresis in the second dimension. …
