Pilot study of 6 weeks of chemoradiotherapy with 5 FU and hydroxyurea in malignant gliomas

Summary In an attempt to improve the primary treatment of malignant gliomas we used a concomitant 6-week course of chemoradiotherapy with 5 fluorouracil (5 FU) and hydroyxurea (HU) in 24 adults with anaplastic astrocytoma (AA) (7 cases) or glioblastomas (GLB) (17 cases). This patient population was characterised by a poor prognostic profile; 50% of cases had biopsic or subtotal surgery and 70% had GLB. Patients received 2 Gy/day 18 MV photons with 300m² of 5 FU in continuous infusion and 500 mg x 4/day per os of HU, five days per week during 6 weeks. Treatment was poorly tolerated in terms of toxicity and implied heavy logistics (hospitalization, central venous access) worsening the quality of life which is already bad in malignant gliomas. Unfortunately we did not improve median survival which does not exceed 26 weeks with 7 long survivors (> 49 weeks). This pilot study does not offer any benefits over current standard approaches. Aggressive locoregional approaches such as this should perhaps be attempted in patients with a better profile.     

Strategies in the treatment of diffuse pontine gliomas: the therapeutic role of hyperfractionated radiotherapy and chemotherapy

This article will review the current treatment of pediatric patients with diffuse pontine gliomas (DPG) and discuss three potential avenues of therapeutic research including (i) radiotherapy (RT) in combination with radiation sensitizers, (ii) dose-intensive, induction chemotherapy with hematopoietic support followed in sequence with RT applied as a consolidation therapy, and (iii) the interleafed application of phase-specific chemotherapeutic agents and hyperfractionated external beam radiotherapy (HFEBRT) referred to as chemoradiotherapy.     

Treatment of oesophageal cancer with preoperative chemoradiotherapy may increase operative mortality

AIMS: This phase II multicentric study evaluates a modified preoperative chemoradiotherapy schedule. METHODS: Patients <75 years with potentially resectable neoplasm were eligible. Treatment included an initial course of CDDP 100 mg/m2 (Day 1) and 5-FU CI 5000 mg/m2 (Days 1-5) followed by 45 Gy (Days 28-63) and 5-FU CI 5000 mg/m2 (Days 28-33), CDDP 75 mg/m2 (Day 56) and 5-FU CI 3750 mg/m2 (Days 56-61). Regional lymph nodes were irradiated. RESULTS: Nineteen patients were studied. Oesophagectomy was performed in 17. Clear margins were achieved in 16 of these. Eight patients showed a pathologic complete response (pCR). One patient died of infection during the preoperative treatment and four died due to acute surgical complications. The study was closed prematurely because of excessive mortality. Median follow-up was 19 months. Local and regional relapse occurred in one and three patients, respectively. Median time and actuarial 3-year of overall survival and progression free rates were 18.6 months and 28%, and 12.7 months and 10.4%, respectively. CONCLUSIONS: This schedule showed a high pCR, resectability and local control rate. Treatment-related mortality limits its clinical applicability, but further investigations are warranted.     

同期放化疗治疗晚期非小细胞肺癌

目的探讨长春瑞滨联合顺铂同期放疗综合治疗晚期非小细胞肺癌的疗效和毒副作用。方法对33例晚期非小细胞肺癌患者进行同期放化疗，化疗在放疗开始时同期进行，用药长春瑞滨25mg／m^2第1、8天静脉滴注；顺铂40mg／m^2第1、2天静脉滴注。28d为1个周期，共给6周期。放疗采用常规分割照射（1．8～2Gy／次，5次／周），总剂量为45～55Gy。治疗结果与同期单纯放疗的41例晚期非小细胞肺癌进行对照。结果放化同期组的近期有效率为57．6％，单纯放疗组为34．1％（x^2=4．06，P〈0．05）。放化同期组1、2年生存率分别为63、6％、39．4％，单纯放疗组分别为29．3％、14．696（1年生存率的卡方检验：x^2=8．74，P〈0．01；2年生存率的卡方检验：x^2=5．87，P〈0．05）。放化同期组肿瘤进展时间平均为10．2个月，单纯放疗组为4．5个月（Log Rank检验：x^2=6．34，P〈0．05）。两组结果相比有显著性差异。两组患者治疗过程中出现的毒副反应主要为骨髓抑制，以及放射性食管炎等。但所有病例均顺利完成治疗过程，无治疗相关死亡。结论长春瑞滨联合顺铂同期放疗可以提高晚期非小细胞肺癌的近期疗效和远期生存率，是一种安全有效的综合治疗手段。     

Definitive Chemoradiotherapy for Oesophageal Cancer — A Promising Start on an Exciting Journey

Despite many advances in the management of oesophageal cancer, survival rates remain poor. Currently there is no clear consensus on the optimum management modality for localised disease. Surgery alone or combined with neoadjuvant chemotherapy or chemoradiotherapy and definitive chemoradiotherapy are all treatment options used for treating selected patient groups throughout the world. This overview discusses the evidence for definitive chemoradiotherapy, its role for certain patient groups and compared with other treatment options and how it has evolved with emerging technologies over recent decades. It highlights some key areas of research for future trials, including more precise treatment delivery, treatment intensification and a possible randomised controlled trial comparing radiation and surgical-based treatment.     

Immunohistological expression of HIF‐1α, GLUT‐1, Bcl‐2 and Ki‐67 in consecutive biopsies during chemoradiotherapy in patients with rectal cancer

The aim of this study was to describe the dynamics of HIF‐1α, GLUT‐1, Bcl‐2 and Ki‐67 during chemoradiotherapy (CRT) of rectal cancer, and to investigate the fluctuation of these biomarkers in relation to pathological response to CRT. The study included 86 patients with rectal adenocarcinoma receiving preoperative CRT (>50.4 Gy and Uracil/Tegafur). Immunohistological expressions of HIF‐1α, GLUT‐1, Bcl‐2 and Ki‐67 were investigated in biopsies taken before treatment, after 2, 4 and 6 weeks of CRT and in specimens from the operation. Decreasing expressions of HIF‐1α, Bcl‐2 and Ki‐67 were observed during CRT, whereas GLUT‐1 overall was unchanged. No significant changes of the markers were observed in the interval between CRT and surgery. A significant association was observed between the presence of residual carcinoma after 6 weeks of treatment and pathological response to CRT, but no association was seen between the fluctuations of any of the markers and response to CRT. This unique material containing specimens before, after and during CRT for rectal cancer demonstrated biological dynamics in HIF‐1α, Bcl‐2 and Ki‐67, but not GLUT‐1, expression during CRT, and a significant association was seen between the presence of residual carcinoma after 6 weeks of treatment and pathological response to CRT.     

Concurrent analysis: validation of the domains within the Birth Satisfaction Scale

Background and aim: Measuring women’s satisfaction with their birth experience has been problematic. Recently, an attempt has been made to capture birth satisfaction’s generalised meaning and incorporate it into an evidenced-based tool. Standard procedures for validation have limitations. Qualitative techniques such as domain analysis offer an alternative and assist in better understanding the importance of each item. This article examines the parsimony of the Birth Satisfaction Scale (BSS), which is a 30-item questionnaire designed to measure satisfaction with childbirth, with women’s actual experience of childbirth. Methods: Primary free text data collected from 207 women who originally tested the BSS was concurrently analysed with first-hand accounts of birth satisfaction collected from 19 qualitative papers. Results: The domain analysis confirmed three explanatory items within the BSS: ‘being in control’, ‘things going as planned’, and ‘being supported’. Conclusions: The BSS accounts for all the analysed data, suggesting it is a robust measure of satisfaction in childbirth. Strengths and limitations of the method are discussed, as are implications for practice. With further development, the instrument could be used to establish correlates with other psychometric measures, i.e. self-efficacy, anxiety, depression, locus of control and bonding; and evaluate models or care systems as a standalone instrument, or as a screening test prior to detailed qualitative work.
