After chemoradiation for localized non-small-cell lung cancer, surgery and prophylactic cranial irradiation (PCI) have been used as additional therapies. Less than a third of patients develop brain recurrences, or have local recurrence as their sole initial site of recurrence; these are groups that would benefit from PCI or surgery, respectively. Pretreatment identification of patients more likely to benefit from surgery or PCI would be useful. A retrospective analysis of 80 patients was performed to determine prognostic factors for such patterns of failure. Twenty-nine patients were subsequently selected for surgery in a nonrandomized manner. Seventeen patients had isolated local initial recurrence …
Sublingual Atropine For Sialorrhea Secondary To Parkinsonism: A Pilot Study, H. Hyson, Andrew Johnson, Mandar Jog
Sublingual Atropine For Sialorrhea Secondary To Parkinsonism: A Pilot Study, H. Hyson, Andrew Johnson, Mandar Jog

Sialorrhea is a relatively common symptom in idiopathic Parkinson's disease and related conditions for which most of the accepted treatments are either highly invasive or may cause substantial systemic side effects. This study describes an open-label pilot study of sublingual atropine drops for the treatment of sialorrhea in 7 patients (6 with Parkinson's disease, 1 with progressive supranuclear palsy). Participants demonstrated statistically significant declines in saliva production, both objectively and subjectively. Self-reported drooling severity showed a significant decline between baseline and 180 minutes, t(6) = 3.240 P < 0.025 (eta(2) = 0.636), and between baseline and 1 week, t(6) = 4.583 …

PURPOSE: Three-dimensional conformal radiation therapy requires the precise definition of the target volume. Its potential benefits could be offset by the inconsistency in target definition by radiation oncologists. In a previous survey of radiation oncologists, a large degree of variation in target volume definition of cervical esophageal cancer was noted for the boost phase of radiotherapy. The present study evaluated whether special training could improve the consistency in target volume definitions. METHODS AND MATERIALS: A pre-training survey was performed to establish baseline values. This was followed by a special one-on-one training session on treatment planning based on the RTOG 94-05 …

Monte Carlo Simulations Of Dna Damage From Incorporated Cold Iodine Following Photoelectrically Induced Auger Electron Cascades, V. Moiseenko, S. Karnas, E. Yu, J. Battista

Radiation-induced damage in nucleosomal DNA from Auger electron cascades due to incorporated cold IUdR has been modelled through Monte Carlo simulations. Probabilities of DNA double strand break (DSB) production following a vacancy in the K, L, M and N shells of iodine are estimated. DSB complexity from the base damage accompanying a break was also estimated. Multiple DSB events were analysed for correlated breaks due to nucleosome periodicity. The probability of an Auger cascade causing at least one DSB strongly depended on the shell in which the initial vacancy was produced. This probability was approximately 0.35 for K and L …

PURPOSE: To investigate the therapeutic usefulness and cost-effectiveness of prophylactic cranial irradiation (PCI) in patients with limited-stage small-cell lung cancer (SCLC) who had achieved a complete remission. METHODS: A retrospective chart review was undertaken of all patients diagnosed in Saskatchewan with SCLC between 1987 and 1998 inclusive. Patients who achieved a complete remission were divided into two groups, depending on whether they underwent PCI (PCI+ and PCI-, respectively). The quality-of-life-adjusted survival was estimated by the Q-TWiST method (quality time without symptoms and toxicity). The mean incremental costs per month of incremental OS were calculated in a cost-effectiveness analysis. RESULTS: Among …
