RESUMO

AIMS: 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18FDG-PET/CT) is routinely used for the pre-treatment staging of oesophageal or gastro-oesophageal junction cancers (EGEJC). The aim of this study was to identify objective 18FDG-PET/CT-derived parameters that can aid in predicting the patterns of recurrence and prognostication in patients with EGEJC. PATIENTS AND METHODS: EGEJC patients referred for consideration of preoperative chemoradiation therapy were identified and clinicopathological data were collected. 18FDG-PET/CT imaging data were reviewed and correlated with treatment outcomes. Maximum standardised uptake value (SUVmax), metabolic tumour volume (MTV) and total lesion glycolysis were assessed and association with recurrence-free survival (RFS), locoregional recurrence-free survival (LR-RFS), oesophageal cancer-specific survival (ECSS) and overall survival were evaluated using receiver operating characteristic curves, as well as Cox regression and Kaplan-Meier models. RESULTS: In total, 191 EGEJC patients completed trimodality treatment and 164 with 18FDG-PET/CT data were included in this analysis. At the time of analysis, 15 (9.1%), 70 (42.7%) and two (1.2%) patients were noted to have locoregional, distant and both locoregional and distant metastases, respectively. The median RFS was 30 months (9.6-50.4) and the 5-year RFS was 31.1%. The 5-year overall survival and ECSS were both noted to be 34.8%. Pre-treatment MTV25 > 28.5 cm3 (P = 0.029), MTV40 > 12.4 cm3 (P = 0.018) and MTV50 > 10.2 cm3 (P = 0.005) predicted for worse LR-RFS, ECSS and overall survival for MTV definition of voxels ≥25%, 40% and 50% of SUVmax. CONCLUSION: 18FDG-PET/CT parameters MTV and total lesion glycolysis are useful prognostic tools to predict for LR-RFS, ECSS and overall survival in EGEJC. MTV had the highest accuracy in predicting clinical outcomes. The volume cut-off points we identified for different MTV thresholds predicted outcomes with significant accuracy and may potentially be used for decision making in clinical practice.

RESUMO

AIM: To determine the efficacy of preoperative chemoradiotherapy as per the CROSS protocol for oesophageal/gastroesophageal junction cancer (OEGEJC), when expanded to patients outside of the inclusion/exclusion criteria defined in the original clinical trial. MATERIALS AND METHODS: Data were collected retrospectively on 229 OEGEJC patients referred for curative-intent preoperative chemoradiotherapy. Outcomes including pathological complete response (pCR), overall survival (OS), cancer-specific survival and recurrence-free survival (RFS) of patients who met CROSS inclusion criteria (MIC) versus those who failed to meet criteria (FMIC) were determined. RESULTS: In total, 42.8% of patients MIC, whereas 57.2% FMIC; 16.6% of patients did not complete definitive surgery. The MIC cohort had higher rates of pCR, when compared with the FMIC cohort (33.3% versus 20.6%, P = 0.039). The MIC cohort had a better RFS, cancer-specific survival and OS compared with the FMIC cohort (P = 0.006, P = 0.004 and P = 0.009, respectively). Age >75 years and pretreatment weight loss >10% were not associated with a poorer RFS (P = 0.541 and 0.458, respectively). Compared with stage I-III patients, stage IVa was associated with a poorer RFS (hazard ratio (HR) = 2.158; 95% confidence interval (CI) = 1.339-3.480, P = 0.001). Tumours >8 cm in length or >5 cm in width had a trend towards worse RFS (HR = 2.060; 95% CI = 0.993-4.274, P = 0.052). CONCLUSION: Our study showed that the robust requirements of the CROSS trial may limit treatment for patients with potentially curable OEGEJC and can be adapted to include patients with a good performance status who are older than 75 years or have >10% pretreatment weight loss. However, the inclusion of patients with celiac nodal metastases or tumours >8 cm in length or >5 cm in width may be associated with poor outcomes.

RESUMO

AIMS: Skin toxicity is a common adverse effect of breast radiotherapy. We investigated whether inverse-planned intensity-modulated radiotherapy (IMRT) would reduce the incidence of skin toxicity compared with forward field-in-field breast IMRT (FiF-IMRT) in early stage breast cancer. MATERIALS AND METHODS: This phase III randomised controlled trial compared whole-breast irradiation with either FiF-IMRT or helical tomotherapy IMRT (HT-IMRT), with skin toxicity as the primary end point. Patients received 50 Gy in 25 fractions and were assessed to compare skin toxicity between treatment arms. RESULTS: In total, 177 patients were available for assessment and the median follow-up was 73.1 months. Inverse IMRT achieved more homogeneous coverage than FiF-IMRT; erythema and moist desquamation were higher with FiF-IMRT compared with HT-IMRT (61% versus 34%; P < 0.001; 33% versus 11%; P < 0.001, respectively). Multivariate analysis showed large breast volume, FiF-IMRT and chemotherapy were independent factors associated with worse acute toxicity. There was no difference between treatment arms in the incidence of late toxicities. The 5-year recurrence-free survival was 96.3% for both FiF-IMRT and HT-IMRT and the 5-year overall survival was 96.3% for FiF-IMRT and 97.4% for HT-IMRT. CONCLUSIONS: Our study showed significant reduction in acute skin toxicity using HT-IMRT compared with FiF-IMRT, without significant reduction in late skin toxicities. On the basis of these findings, inverse-planned IMRT could be used in routine practice for whole-breast irradiation with careful plan optimisation to achieve the required dose constraints for organs at risk.

RESUMO

1. The Psychopharmacology RACE is an interactive, innovative game that emphasizes group teaching about psychiatric medications and disorders at the clients' levels of functioning. 2. Implementation of the Psychopharmacology RACE provides the opportunity to structure a medication group, impart information, and facilitate the development of therapeutic group factors. 3. Interactive group learning with the Psychopharmacology RACE can be a useful tool to enhance learning when clients are unable to read and understand written materials.

RESUMO

Theoretical support is evaluated for nursing students' use of an innovative educational intervention, the Psychopharmacology R.A.C.E. (Wissman and Tankel, Kansas City, MO) game, as an empowerment tool with mental health clients. Based on mutual trust and respect, the interpersonal process occurs between an individual or group (e.g., client, student) with a desire for competency growth (e.g., knowledge, proactive health behaviors, negotiation), and development of a sense of control and self-determination and another individual or group (e.g., nurse) who serves as an enabler, supporter, and resource mobilizer. A review of empowerment literature identifies: (1) support of education as an empowerment tool; (2) identification of specific teaching methods and behaviors that promote empowerment; (3) empowerment as an outcome of involvement; and (4) support of the empowerment value of group participation. Preliminary clinical observations reveal strong support for nursing students' use of the Psychopharmacology R.A.C.E. game as a method to empower mental health clients.

RESUMO

1 In this era of rapidly changing mental health services and new psychotropic drugs, health professionals are challenged to develop and maintain psychopharmacology competencies. 2 The Psychopharmacology RACE provides an interactive and learner-oriented method of developing and assessing theoretical and clinical competencies for psychopharmacology. 3 The Psychopharmacology RACE is also well suited for modification and application toward the professional development of nurses and the education of clients.

RESUMO

Explanations for the high prevalence of alcohol and drug abuse in schizophrenia purport that substance use is related to social-affiliative needs or to symptom regulation. Neither explanation was adequate in describing substance-use episodes in the present longitudinal study. The study involved repeated interviews of 10 individuals with schizophrenia about their internal and external environment during substance use. Qualitative analyses of interview responses showed variability in multiple versus single episodes in a day and categories labeled Activities Prior to Use and Social Context of Use. Individual subject's responses each had a unique pattern that characterized their substance-use episodes.
