Computed Tomography To Assess Pulmonary Injury Associated With Concurrent Chemo-Radiotherapy For Inoperable Non-Small Cell Lung Cancer, Galit Aviram, Edward Yu, Patricia Tai, Michael Lefcoe

Edward Yu

OBJECTIVE: To characterize serial computed tomography (CT) findings of pulmonary injury after a uniform regimen of concurrent chemo-radiotherapy in inoperable non-small cell lung cancer, and to compare the radiation-induced lung toxicity with other concurrent chemo-radiation regimens. METHODS: Twenty-four patients with advanced non-small cell lung cancer received 2 induction cycles of cisplatin and vinblastine, followed by 2 further cycles of cisplatin and vinblastine, concurrent with 60 Gy radiation at 2 Gy per fraction. Radiation-induced lung injury in the acute and chronic phases was assessed by serial CT scans and compared with preradiation baseline scans. Acute radiation pneumonitis was evaluated using the …

Morphological Pattern Of Salivary Gland Tumours, M. S. Gill, S. Muzaffar, I. N. Soomro, Naila Kayani, A. S. Hussainy, Shahid Pervez, S. H. Hasan

Department of Pathology and Laboratory Medicine

Objective: To delineate the spectrum of salivary gland tumors in our setup.

Setting: The Aga Khan University Medical Centre, Karachi.

Method: Tumors were analysed considering histological type, age and sex of the patients and anatomic location. The diagnosis of individual tumours was based on the 1991 World Health Organisation Classification.

Results: During the span of eight years (1991-1998), 379 cases of salivary gland tumours were diagnosed. Of these, 205 (65.7%) were male and 174 (34.3%) were female. The median age at the time of diagnosis was 35 years. The median age for patients with malignant lesions (44 years) was 12 …

Therapeutic Electromagnetic Field Effects On Angiogenesis And Tumor Growth, C. Douglas Williams, Marko S. Markov, W. Elaine Hardman, Ivan L. Cameron

Biochemistry and Microbiology

Background: A new approach to cancer therapy based on the application of therapeutic electromagnetic fields (TEMF) has been developed by EMF Therapeutics, Inc., Chattanooga, TN, USA. This study was designed to assess the effect of TEMF on tumor vascularization and growth of murine 16/C mammmary adenocarcinoma cells in C3H/HeJ mice.

Materials and Methods: Implanted tumors were allowed to grow for seven days until the tumor volume reached 100 mm3 before treatment was started. Mice (20 per control, 10 per EMF exposed group) received treatment (10 minutes per day with 0, 10 mT, 15 mT or 20 mT) with a 120 …

Monte Carlo Simulations And Measurement Of Dna Damage From X-Ray-Triggered Auger Cascades In Iododeoxyuridine (Iudr), S. Karnas, V. Moiseenko, E. Yu, P. Truong, J. Battista

Edward Yu

We investigated the DNA damage from Auger electrons emitted from incorporated stable iodine (127I), following photoelectric absorption of external x-rays. The effectiveness of the Auger electrons in producing DNA double-strand breaks (DSB) was determined theoretically, using Monte Carlo simulations of the radiation physics and chemistry, and was shown to be in reasonable agreement with DNA damage measured using the comet assay. The DSB yields were measured in CHO cells for 60Co (as a non-Auger-promoting radiation) and for tungsten-filtered 100 kVp x-rays capable of producing Auger electron emission. The theoretical study showed that on average, 2.5 Auger electrons were emitted for …

Using Treatment Interruptions To Palliate The Toxicity From Concurrent Chemoradiation For Limited Small Cell Lung Cancer Decreases Survival And Disease Control, Gregory Videtic, Karen Fung, Anna Tomiak, Larry Stitt, A. Dar, Pauline Truong, Edward Yu, Mark Vincent, Walter Kocha

Edward Yu

BACKGROUND AND PURPOSE: We analyzed the impact on survival outcomes of treatment interruptions due to toxicity arising during the concurrent phase of chemotherapy/radiotherapy (ChT/RT) for our limited-stage small-cell cancer (LSCLC) population over the past 10 years. MATERIALS AND METHODS: From 1989 to 1999, 215 patients received treatment for LSCLC, consisting of six cycles of alternating cyclophosphamide/doxorubicin or epirubicin/vincristine (CAV; CEV) and etoposide/cisplatin (EP). Thoracic RT was started with EP at either the second or third cycle (85% of patients). RT dose was either 40 Gy in 15 fractions over 3 weeks or 50 Gy in 25 fractions over 5 weeks, …

Practice Guideline On Prophylactic Cranial Irradiation In Small-Cell Lung Cancer, Jaro Kotalik, Edward Yu, Barbara Markman, William Evans

Edward Yu

Purpose: To develop an evidence-based clinical practice guideline that would address the following questions: (a) What is the role of prophylactic cranial irradiation (PCI) in patients with limited or extensive stage small-cell lung cancer (SCLC) who have achieved complete remission in response to induction therapy (chemotherapy or chemoradiotherapy)? (b) What dose and fractionation schedules of PCI are optimal? (c) Does the use of PCI in patients with SCLC in complete remission affect quality of life? Survival, disease-free survival, quality of life, and adverse effects were the outcomes of interest. Methods and materials: A systematic review of the published literature was …

OBJECTIVE: To assess the value of extended volume irradiation with anastomotic coverage in high risk resected esophageal cancer patients.

METHOD: A retrospective study was undertaken at LRCC from 1989-1999 for high risk resected esophageal cancer patients. Adjuvant treatments consisted of 4 cycles of chemotherapy (epirubicin/fluorouracil/cisplatin or cisplatin/fluorouracil), and local regional irradiation with or without coverage of the anastomotic site. Radiation dose ranged from 45-60Gy at 1.8-2.0 Gy/fraction given with initial anterior-posterior/posterior-anterior arrangement with either extended (with anastomotic coverage) or small (without anastomotic coverage) field followed by oblique fields for boost.

RESULT: One hundred eighty-eight charts were reviewed. Seventy-two patients were …

Abnormal Expression Of P27kip1 Protein In Levator Ani Muscle Of Aging Women With Pelvic Floor Disorders – A Relationship To The Cellular Differentiation And Degeneration, Antonin Bukovsky, Pleas Copas, Michael R. Caudle, Maria Cekanova Ms, Rndr, Phd, Tamara Dassanayake, Bridgett Asbury, Stuart E. Van Meter, Robert F. Elder, Jeffrey B. Brown, Stephanie B. Cross

Maria Cekanova MS, RNDr, PhD

Background Pelvic floor disorders affect almost 50% of aging women. An important role in the pelvic floor support belongs to the levator ani muscle. The p27/kip1 (p27) protein, multifunctional cyclin-dependent kinase inhibitor, shows changing expression in differentiating skeletal muscle cells during development, and relatively high levels of p27 RNA were detected in the normal human skeletal muscles.

Methods Biopsy samples of levator ani muscle were obtained from 22 symptomatic patients with stress urinary incontinence, pelvic organ prolapse, and overlaps (age range 38–74), and nine asymptomatic women (age 31–49). Cryostat sections were investigated for p27 protein expression and type I (slow …

Department of Radiation Oncology Faculty Papers

BACKGROUND: Mutations in BRCA1 and BRCA2 account for approximately 50% of breast cancer families with more than four affected cases, whereas exonic mutations in p53, PTEN, CHK2 and ATM may account for a very small proportion. It was recently reported that an intronic variant of p53--G13964C--occurred in three out of 42 (7.1%) 'hereditary' breast cancer patients, but not in any of 171 'sporadic' breast cancer control individuals (P = 0.0003). If this relatively frequent occurrence of G13964C in familial breast cancer and absence in control individuals were confirmed, then this would suggest that the G13964C variant plays a role in …

Cellular Senescence: Ex Vivo P53-Dependent Asymmetric Cell Kinetics., Lakshmi Rambhatla, Shirley A. Bohn, Patrizia B. Stadler, Jonathan T. Boyd, Ronald A. Coss, James L. Sherley

Department of Radiation Oncology Faculty Papers

Although senescence is a defining property of euploid mammalian cells, its physiologic basis remains obscure. Previously, cell kinetics properties of normal tissue cells have not been considered in models for senescence. We now provide evidence that senescence is in fact the natural consequence of normal in vivo somatic stem cell kinetics extended in culture. This concept of senescence is based on our discovery that cells engineered to conditionally express the well-recognized tumor suppressor protein and senescence factor, p53, exhibit asymmetric cell kinetics. In vivo, asymmetric cell kinetics are essential for maintenance of somatic stem cells; ex vivo, the same cell …
