Relapse Analysis of Irradiated Patients Within the HD15 Trial of the German Hodgkin Study Group
2015
Purpose To determine, in the setting of advanced-stage of Hodgkin lymphoma (HL), whether relapses occur in the irradiated planning target volume and whether the definition of local radiation therapy (RT) used by the German Hodgkin Study Group (GHSG) is adequate, because there is no harmonization of field and volume definitions among the large cooperative groups in the treatment of advanced-stage HL. Methods and Materials All patients with residual disease of ≥2.5 cm after multiagent chemotherapy (CTX) were evaluated using additional positron emission tomography (PET), and those with a PET-positive result were irradiated with 30 Gy to the site of residual disease. We re-evaluated all sites o…
Tax Competition with Intermunicipal Cooperation
2020
We study local tax competition when municipalities can voluntarily cooperate with neighboring jurisdictions. In France, the strongest form of cooperation among municipalities occurs by forming an “establishment for inter-municipal cooperation” (EIMC). We study how interjurisdictional policy interdependence differs between competing municipalities within the same EIMC and competing municipalities outside of the cooperative unit. We apply the estimation strategy of Kelejian and Piras (2014) to resolve the endogeneity of the decision to cooperate with other municipalities. We find that strategic interactions among peer members of the same EIMC are less intense than strategic interactions with …
Preliminary Results of Two Eortc Randomized Trials in Previously Untreated Patients with Advanced T3 — T4 Prostatic Cancer
1983
At the end of 1976 and the beginning of 1977 respectively, the EORTC Genito-Urinary Tract Cancer Cooperative Group started two randomized phase III protocols in previously untreated patients with advanced T3–4 prostatic cancer (1–3). The first trial, 30762, compared Stilboestrol and Estracyt, while the second, 30761, was a randomized comparison of Stilboestrol, Cyproterone Acetate and Medroxyprogesterone Acetate. Both trials have now been closed to patient entry and the principal endpoints of the studies analyzed. This paper will present the interim results which have emerged from these two studies.
