RESUMEN

AIMS: Postoperative vaginal vault brachytherapy (VBT) reduces local recurrence in operable endometrial cancer. Radiographer-led delivery of VBT, carried out without image guidance, was implemented at Addenbrooke's in 2010 to maximise skills mix and to improve service delivery. The purpose of this study was to evaluate the safety and effectiveness of this service. MATERIALS AND METHODS: This was a single-centre retrospective study of endometrial cancer patients treated with postoperative high dose rate VBT ± external beam radiotherapy (EBRT) between January 2010 and December 2016. RESULTS: In total, 414 patients were analysed: 307 received adjuvant VBT alone and 107 patients received pelvic EBRT followed by VBT. Thirty-seven per cent of patients receiving VBT alone were high risk according to ESMO-ESGO-ESTRO criteria. After a median follow-up of 59 months (range 2-118), 9/414 (2.2%) patients had isolated vaginal recurrences, 15/414 (3.6%) had locoregional recurrence (vaginal, pelvic node or both), whereas 62/414 (15%) patients had distant recurrence. The 5-year actuarial isolated vaginal recurrence rate was 2.3% (VBT alone 2.1%, EBRT + VBT 3.0%). Grade 3 urinary or bowel toxicity occurred in 2/414 (0.6%) patients treated with EBRT and VBT. None of the patients treated with VBT alone had grade 3 complications. CONCLUSION: Radiographer-led delivery of VBT, without the use of image guidance, is a safe and effective service.

RESUMEN

Borderline sarcomas and smooth muscle tumours of uncertain malignant potential (STUMP) have an unpredictable clinical behaviour with frequent local recurrences and rarely, metastases. We review the current management of common subtypes of borderline sarcomas and STUMP.

RESUMEN

Merkel cell carcinoma is a rare skin tumour with a poor outcome and high rates of both local and distant recurrence despite radical management. We review the management of local and locoregional disease, and the role of sentinel lymph node biopsy in staging. This overview aims to highlight some of the controversies regarding the current treatment of this disease, which seems to be on the increase. Data are conflicting as to whether there is any survival benefit from adjuvant primary site or regional nodal irradiation, partly due to the lack of prospective clinical trials. We also review the evolving role of primary radiotherapy and suggest areas where ongoing research is urgently required.

RESUMEN

In the UK, the standard of care for esophageal cancer has generally combined surgery with neoadjuvant chemotherapy, with definitive chemoradiotherapy (dCRT) being reserved for certain subgroups. Chemoradiotherapy followed by surgery (trimodality therapy) has not been widely adopted. The outcomes of patients undergoing dCRT or trimodality therapy at our cancer center between 2004 and 2012 were restrospectively analyzed. Trimodality therapy was offered to selected patients of good performance status (World Health Organisation performance status 0/1), with squamous cell carcinoma or bulky adenocarcinoma. dCRT was offered to patients of good PS but with comorbidities, upper third tumors or at patient's request. Patients received four cycles of chemotherapy with a platinum agent (mostly cisplatin) and a fluoropyrimidine (mostly 5-fluorouracil) over a total of 11 weeks. Cycles 3 and 4 were given concurrently with radiotherapy: 50 Gy in 25 fractions for dCRT and 45 Gy in 25 fractions in the trimodality group. Surgery occurred 8-10 weeks following the completion of chemoradiotherapy. The cut-off length for maximum gross tumor volume length was 10 cm. One hundred two patients were included (47 received dCRT, and 55 received trimodality treatment). The majority of tumors were stage III (80.4%), and two-thirds were located in the distal esophagus (64.7%). Median follow-up was 44 months. The 2-year overall survival (OS) was 57.3% (median OS 39.7 months) for the dCRT group and 77.8% (median not reached) for the trimodality group. The 5-year OS rates were 38% and 58%, respectively. Postoperative mortality rate was low at 1.8%, and the pathological complete response rate was 23.6%. In conclusion, trimodality treatment for patients with esophageal and junctional gastroesophageal tumors offers high rates of 2-year survival, and the potential for long-term cure. dCRT is an established alternative for patients that are not fit or suitable for surgery.

RESUMEN

AIMS: This report reviews current radiotherapy practice across the UK in the management of lung cancer, and the way new treatments and technologies are being introduced, where improvements have occurred, and where work is still required. We wanted to determine adherence to both National Radiotherapy Advisory Group and National Institute for Health and Clinical Excellence (NICE) guidance. This survey was conducted on behalf of the Department of Health Lung Cancer & Mesothelioma Advisory Group. MATERIALS AND METHODS: We sent a questionnaire to all UK radiotherapy departments. It covered radical radiotherapy dose fractionation, the use of concurrent or sequential chemotherapy for both non-small cell and small cell lung cancers, the use of continuous hyperfractionated accelerated radiotherapy, new radiotherapy techniques, the use of positron emission tomography/computed tomography for planning purposes and patient accrual into current National Cancer Research Network UK trials. RESULTS: This UK-wide survey of radiotherapy practice for lung cancer showed broad compliance with NICE clinical guidance, but highlighted significant variation in fractionation schedules and the use of concomitant chemoradiotherapy. Clinical trial entry into lung cancer radiotherapy trials was variable and many centres are not fully participating in recruitment into these trials. CONCLUSIONS: This report has shown the variability of radiotherapy provision nationally. Current practice is largely consistent with current and updated NICE recommendations and best practice and should be recognised as such. It has also highlighted areas where improvements are still needed, particularly fractionation and new technologies. One particular aspect of concern is the poor recruitment to current UK-based clinical trials in lung cancer.

RESUMEN

Metastatic spinal cord compression is a frequent medical emergency, and the most common treatment offered is radiotherapy. The routine treatment prescription for spinal cord compression in the UK is 20 Gy in five daily fractions delivered over 1 week. Here, we evaluate the evidence base for the radiotherapy dose for spinal cord compression. Evidence from the four prospective studies conducted so far and retrospective studies does not support a uniform dose of 20 Gy for all patients with spinal cord compression. Available evidence suggests that the radiotherapy dose should be tailored to the individual patient, depending on the subtype of the tumour, the extent of metastatic disease and expected survival. A risk stratification for the optimum dose prescription for patients with spinal cord compression is recommended.

RESUMEN

The application of the fetal biophysical profile score in the management of 2,400 high-risk pregnancies was assessed. The negative predictive value for normal perinatal outcome was not improved compared to single variable tests. The positive predictive value for abnormal perinatal outcome was improved. The overall perinatal mortality in 2,485 fetuses was 9.2 per 1,000. In the 1,980 fetuses with a normal biophysical profile score within 7 days of delivery, excluding lethal anomalies, the perinatal mortality was 1 per 1,000. Fetal movement counting is supported as the most valid and appropriate test for universal fetal screening.
