The aim of this study was to analyze the survival of a series of patients diagnosed as having brain stem tumors by computerized tomography scan, magnetic resonance imaging and/or biopsy and treated with megavoltage irradiation. Fifty-three patients presenting to the Peter MacCallum Cancer Institute with a diagnosis of brain stem tumor from January 1980 to(More)
In patients with cervical node metastases from an unknown primary malignancy, there is unresolved controversy regarding the utility of elective irradiation of putative pharyngeal primary sites as part of the management plan. We analysed the experience of the Peter MacCallum Cancer Institute to assess the risk of withholding mucosal irradiation in relation(More)
BACKGROUND Management of patients with head and neck carcinoma and advanced nodal disease is controversial. The purpose of this analysis was to evaluate the efficacy and toxicity of definitive radiotherapy followed by planned neck dissection in patients with bulky neck disease. MATERIALS AND METHODS The records of 52 patients who were treated between 1989(More)
PURPOSE To determine the maximum-tolerated dose of tirapazamine when combined with cisplatin and radiation in patients with T3/4 and/or N2/3 squamous cell carcinoma of the head and neck. PATIENTS AND METHODS The starting schedule was conventionally fractionated radiotherapy (70 Gy in 7 weeks) with concomitant cisplatin 75 mg/m2 and tirapazamine 290 mg/m2(More)
The authors present 3 years of experience in using digitally reconstructed radiographs (DRR) for radiotherapy planning and verification. Comparison is made with simulation film (SF), to illustrate the advantages of DRR over SF. Emphasis is placed on using the appropriate equipment and applying the correct technique. A brief discourse on the principle of CT(More)
The electrocardiographic (ECG) findings in patients with pulmonary embolism (PE) and no previous cardiopulmonary disease are well documented; however, investigation of the relation of ECG abnormalities to right ventricular (RV) enlargement has been limited. The purpose of the present investigation was to assess further the relation of ECG changes in acute(More)
From 1969-1985 two types of fractionation schedules with similar time, dose, and fractionation factor (TDF) values were used to treat 197 patients with Tis, T1, and T2 squamous cell carcinoma of the vocal cord. One hundred and thirty-one patients were treated with conventional daily 2.0 Gy fractions, and 66 patients were treated once per week with large(More)
Fifty-one patients with recurrent or advanced squamous cell carcinoma of the head and neck received carboplatin 70 mg/m2/day bolus X 5 days i.v. and 5-fluorouracil (5-FU) 1000 mg/m2/day by continuous infusion i.v. for 5 days as initial chemotherapy. There were four complete responders (CR) and 12 partial responders (PR). Durations of CR were 6.8 months,(More)
INTRODUCTION Establishing a boot camp curriculum is pertinent for emergency medicine (EM) residents in order to develop proficiency in a large scope of procedures and leadership skills. In this article, we describe our program's EM boot camp curriculum as well as measure the confidence levels of resident physicians through a pre- and post-boot camp survey.(More)
