Purpose: The purpose of this study was to evaluate the impact of FDG-PET following chemoradiotherapy (CRT) on treatment planning and survival in patients with oesophageal cancer (OC).
Methods: Fifty-three consecutive OC patients had a post-treatment PET scan to evaluate tumour response to CRT prior to possible surgery. Baseline pre-CRT PET was performed in 33 patients.
Purpose: To evaluate the clinical impact of FDG-PET in staging oesophageal cancer and whether this information improves prognostic stratification.
Methods: Impact was based on comparison of a prospectively recorded pre-PET plan with post-PET treatment in 68 consecutive patients undergoing primary staging. Survival was analysed using the Kaplan-Meier product limit method and the Cox proportional hazards regression model.
Objective: Several studies have identified that adjuvant chemotherapy for breast cancer is associated with cognitive impairment; however, the magnitude of this impairment is unclear. This study assessed the severity and nature of cognitive impairment associated with adjuvant chemotherapy by conducting a meta-analysis of the published literature to date.
Method: Six studies (five cross-sectional and one prospective) meeting the inclusion criteria provided a total of 208 breast cancer patients who had undergone adjuvant chemotherapy, 122 control participants and 122 effect sizes (Cohen's d) falling into six cognitive domains.
Background: This study evaluates the utility of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) in patients with a node-positive mucosal head and neck squamous cell carcinoma who achieved a complete response at the primary site but had a residual mass in the neck 8 weeks or more after definitive (chemo)radiotherapy.
Methods: Between October 1996 and July 2002, 39 eligible patients were identified. The reference PET scan was performed at a median of 12 weeks (range, 8-32 weeks) after treatment.
Background: The present paper assesses treatment outcomes in a series of 20 patients with sinonasal mucosal melanoma (SNMM) over 11 years.
Methods: All patients who presented to a single institution between 1991 and 2002 with a diagnosis of SNMM had their treatment reviewed and outcomes determined.
Results: Twenty patients presented to our institution with SNMM over the study period.
Postoperative chemoradiotherapy for high-risk head-and-neck squamous cell carcinoma.
Int J Radiat Oncol Biol Phys
October 2004
Purpose: To describe the use of postoperative concurrent chemoradiotherapy, with either weekly cisplatin or carboplatin, for high-risk head-and-neck squamous cell carcinoma (HNSCC) in a single institutional setting.
Methods And Materials: Between July 1999 and January 2003, 47 patients were treated with postoperative chemoradiotherapy.
Results: Of the 47 patients, 41 (87%) had Stage III-IV disease.
Background: Sinonasal undifferentiated carcinoma (SNUC) is an uncommon malignancy associated with poor prognosis. The optimal treatment approach for SNUC has not been established was performed.
Methods: A retrospective review of all patients with SNUC seen at the Peter MacCallum Cancer Centre over a 12-year period.
Background: The purpose of this study was to evaluate the local control, pattern of recurrence, overall survival, and prognostic factors of patients with squamous cell carcinoma (SCC), adenocarcinoma, and undifferentiated carcinoma of the paranasal sinuses (PNS) and nasal cavity (NC) presenting to our center for curative treatment over a 10-year period.
Methods: Between 1991 and 2000, 60 patients with SCC (n = 32), adenocarcinoma (n = 25), and undifferentiated carcinoma (n = 3) of the PNS or NC were identified. Forty patients received surgery and postoperative radiotherapy, four surgery alone; 11, radiotherapy alone; three radical radiotherapy after surgical recurrence; one, chemoradiotherapy and surgery; and one, induction chemotherapy followed by radiotherapy.
Purpose: To describe the psychometric characteristics of the Impact of Vision Impairment (IVI) Profile and evaluate its validity and reliability over time and between different forms of administration.
Methods: The IVI is a 32-item questionnaire developed to measure the impact of vision impairment on restriction of participation in daily activities in five domains of functioning. Each item is rated on a six-level scale from "no difficulty" to "can't do because of vision.
Aim: To investigate factors related to the use of eye care services in Australia.
Methods: Health, eye care service use, and sociodemographic data were collected in a structured interview of participants in a population based study. All participants had a standard eye examination.
