      The aims of this study were to assess changes in quality of life (QoL) scores in relation to radical radiotherapy for gynaecological cancer (before and after treatment up to 3 years), and to identify the effect that late treatment effects have on QoL. This was a prospective study involving 225 gynaecological cancer patients. A QoL instrument (European Organisation for the Research and Treatment of Cancer QLQ-C30) and late treatment effect questionnaire (Late Effects Normal Tissues - Subjective Objective Management Analysis) were completed before and after treatment (immediately after radiotherapy, 6 weeks, 12, 24 and 36 months after treatment). Most patients had acute physical symptoms and impaired functioning immediately after treatment. Levels of fatigue and diarrhoea only returned to those at pre-treatment assessment after 6 weeks. Patients with high treatment toxicity scores had lower global QoL scores. In conclusion, treatment with radiotherapy for gynaecological cancer has a negative effect on QoL, most apparent immediately after treatment. Certain late treatment effects have a negative effect on QoL for at least 2 years after radiotherapy. These treatment effects are centred on symptoms relating to the rectum and bowel, for example, diarrhoea, tenesmus and urgency. Future research will identify specific symptoms resulting from late treatment toxicity that have the greatest effect on QoL; therefore allowing effective management plans to be developed to reduce these symptoms and improve QoL in gynaecological cancer patients.

      OBJECTIVES: Quality of life studies have shown no detrimental effect with radiotherapy (RT) in patients who have a total laryngectomy. We wished to determine the effect of RT (initial or postoperative) specifically on the swallowing and voice function in patients treated by total laryngectomy (TL) for carcinoma of the larynx. DESIGN: Multicenter chart review. SETTING: Multicenter study in the Greater Manchester and Lancashire area. PARTICIPANTS: A total of 121 postlaryngectomy patients all of whom had completed definitive treatment at least 6 months before this study. Twenty-six patients had total laryngectomy as a single modality treatment and 95 had total laryngectomy and radiotherapy. MAIN OUTCOME MEASURES: Swallowing (solid food, soft diet or fluid/PEG) and voice development. RESULTS: Swallowing was better in the group who had no radiotherapy (P = 0.0037). There was no difference in voice function between the two groups. We also demonstrated that females had a worse swallowing outcome (P = 0.0101), as did advanced nodal stage (P = 0.001). CONCLUSIONS: RT adversely affects the swallowing results but not the speech results after TL when given either as initial treatment or postoperatively. This should be kept in mind in the decision-making process in the treatment of patients with carcinoma of the larynx.
    • Impact on survival of intensive follow up after curative resection for colorectal cancer: systematic review and meta-analysis of randomised trials.

      Renehan, Andrew G; Egger, Matthias; Saunders, Mark P; O'Dwyer, Sarah T; Department of Surgery, Christie Hospital NHS Trust, Manchester M20 4BX. arenehan@picr.man.ac.uk (2002-04-06)
      OBJECTIVE: To review the evidence from clinical trials of follow up of patients after curative resection for colorectal cancer. DESIGN: Systematic review and meta-analysis of randomised controlled trials of intensive compared with control follow up. MAIN OUTCOME MEASURES: All cause mortality at five years (primary outcome). Rates of recurrence of intraluminal, local, and metastatic disease and metachronous (second colorectal primary) cancers (secondary outcomes). RESULTS: Five trials, which included 1342 patients, met the inclusion criteria. Intensive follow up was associated with a reduction in all cause mortality (combined risk ratio 0.81, 95% confidence interval 0.70 to 0.94, P=0.007). The effect was most pronounced in the four extramural detection trials that used computed tomography and frequent measurements of serum carcinoembryonic antigen (risk ratio 0.73, 0.60 to 0.89, P=0.002). Intensive follow up was associated with significantly earlier detection of all recurrences (difference in means 8.5 months, 7.6 to 9.4 months, P<0.001) and an increased detection rate for isolated local recurrences (risk ratio 1.61, 1.12 to 2.32, P=0.011). CONCLUSIONS: Intensive follow up after curative resection for colorectal cancer improves survival. Large trials are required to identify which components of intensive follow up are most beneficial.

    • IMRT dose fractionation for head and neck cancer: variation in current approaches will make standardisation difficult.

      Ho, Kean F; Fowler, Jack F; Sykes, Andrew J; Yap, Beng K; Lee, Lip W; Slevin, Nicholas J; Academic Department of Radiation Oncology, University of Manchester, Christie Hospital, Wilmslow Road, Manchester, UK. (2009)
      INTRODUCTION: Altered fractionation has demonstrated clinical benefits compared to the conventional 2 Gy/day standard of 70 Gy. When using synchronous chemotherapy, there is uncertainty about optimum fractionation. IMRT with its potential for Simultaneous Integrated Boost (SIB) adds further to this uncertainty. This survey will examine international practice of IMRT fractionation and suggest possible reasons for diversity in approach. MATERIAL AND METHODS: Fourteen international cancer centres were surveyed for IMRT dose/fractionation practised in each centre. RESULTS: Twelve different types of dose fractionation were reported. Conventional 70-72 Gy (daily 2 Gy/fraction) was used in 3/14 centres with concurrent chemotherapy while 11/14 centres used altered fractionation. Two centres used >1 schedule. Reported schedules and number of centres included 6 fractions/week DAHANCA regime (3), modest hypofractionation (< or =2.2 Gy/fraction) (3), dose-escalated hypofractionation (> or =2.3 Gy/fraction) (4), hyperfractionation (1), continuous acceleration (1) and concomitant boost (1). Reasons for dose fractionation variability include (i) dose escalation; (ii) total irradiated volume; (iii) number of target volumes; (iv) synchronous systemic treatment; (v) shorter overall treatment time; (vi) resources availability; (vii) longer time on treatment couch; (viii) variable GTV margins; (ix) confidence in treatment setup; (x) late tissue toxicity and (xi) use of lower neck anterior fields. CONCLUSIONS: This variability in IMRT fractionation makes any meaningful comparison of treatment results difficult. Some standardization is needed particularly for design of multi-centre randomized clinical trials.

    • Inter-fraction motion and dosimetric consequences during breast intensity-modulated radiotherapy (IMRT).

      Jain, Pooja; Marchant, Thomas E; Green, Melanie M; Watkins, Gillian R; Davies, Julie; McCarthy, Claire; Loncaster, Juliette A; Stewart, Alan L; Magee, Brian; Moore, Christopher J; et al. (2009-01)
      BACKGROUND AND PURPOSE: Intensity-modulated radiotherapy (IMRT) can improve dose homogeneity within the breast planned target volume (PTV), but may be more susceptible to patient/organ motion than standard tangential radiotherapy (RT). We used daily cone-beam CT (CBCT) imaging to assess inter-fraction motion during breast IMRT and its subsequent impact on IMRT and standard RT dose homogeneity. MATERIALS AND METHODS: Ten breast cancer patients selected for IMRT were studied. CBCT images were acquired immediately after daily treatment. Automatic image co-registration was used to determine patient positioning variations. Daily PTV contours were used to calculate PTV variations and daily delivered IMRT and theoretically planned tangential RT dose. RESULTS: Group systematic (and random) setup errors detected by CBCT were 5.7 (3.9)mm laterally, 2.8 (3.5)mm vertically and 2.3 (3.2)mm longitudinally. Rotations >2 degrees in any axis occurred on 53/106 (50%) occasions. Daily PTV volume varied up to 23%. IMRT dose homogeneity was superior at planning and throughout the treatment compared with standard RT (1.8% vs. 15.8% PTV received >105% planned mean dose), despite increased motion sensitivity. CONCLUSIONS: CBCT revealed inadequacies of current patient positioning and verification procedures during breast RT and confirmed improved dose homogeneity using IMRT for the patients studied.
    • Irinotecan+5-fluorouracil with concomitant pre-operative radiotherapy in locally advanced non-resectable rectal cancer: a phase I/II study.

      Iles, S M; Gollins, Simon W; Susnerwala, Shabbir; Haylock, B; Myint, A Sun; Biswas, A; Swindell, Ric; Levine, Edward; Department of Clinical Oncology, The Christie Hospital NHS Trust, Manchester M20 4BX, UK. (2008-04-08)
      In the UK, 10% of patients diagnosed with rectal cancer have inoperable disease at presentation. This study ascertained whether the resectability rate of inoperable locally advanced rectal cancer was improved by administration of intravenous irinotecan, 5-fluorouracil (5-FU) and pelvic radiotherapy. During phase I of the trial (n=12), the dose of irinotecan was escalated in three-patient cohorts from 50 mg m(-2) to 60 mg m(-2) to 70 mg m(-2) to identify the maximum tolerated dose (60 mg m(-2)). In phase II, 31 patients with non-resectable disease received 45 Gy radiotherapy and 5-FU infusions (200 mg m(-2) per day) for 5 weeks. Irinotecan (60 mg m(-2)) was given on days 1, 8, 15 and 22. After treatment, patients were operated on if possible. Thirty patients completed the protocol, 28 underwent surgery. Before surgery, MRI restaging of 24 patients showed that 19 (79%) had a reduction in tumour stage after treatment (seven complete clinical response and 12 partial). Of 27 patients followed up after surgery, 22 (81%) had clear circumferential resection margins. Disease-free and overall survival estimates at 3 years were 65 and 90%, respectively. The regimen was well tolerated. Irinotecan, 5-FU and radiotherapy results in tumour downgrading, allowing resection of previously inoperable tumour with acceptable toxicity.
    • Late-onset bowel dysfunction after pelvic radiotherapy: a national survey of current practice and opinions of clinical oncologists.

      Henson, Caroline C; Andreyev, H J; Symonds, R P; Peel, D; Swindell, Ric; Davidson, Susan E; The Christie NHS Foundation Trust, Manchester, UK. Caroline.Henson@christie.nhs.uk (2011-10)
      Seventeen thousand patients receive treatment with radical pelvic radiotherapy annually in the UK. It is common for patients to develop gastrointestinal symptoms after treatment. The aim of this study was to determine the current practice of clinical oncologists in the UK with respect to late-onset bowel dysfunction after pelvic radiotherapy, and to discuss the wider issues surrounding current and future service provision for this patient group.
    • Lymphocyte telomere length correlates with in vitro radiosensitivity in breast cancer cases but is not predictive of acute normal tissue reactions to radiotherapy.

      Iwasaki, Toshiyasu; Robertson, Naomi; Tsigani, Theodora; Finnon, Paul; Scott, David A; Levine, Edward; Badie, Christophe; Bouffler, Simon; Radiation Effects Department, Health Protection Agency, Centre for Radiation, Chemical and Environmental Hazards, Radiation Protection Division, Chilton, Didcot, Oxfordshire, UK. (2008-04)
      PURPOSE: To examine the hypothesis that lymphocyte telomere length may be predictive of both breast cancer susceptibility and severity of acute reactions to radiotherapy. MATERIALS AND METHODS: Peripheral blood lymphocyte cultures from breast cancer patients (with normal or severe skin reactions to radiotherapy) and normal individuals were assessed for in vitro radiosensitivity as measured by apoptosis, cell cycle delay and cytotoxicity. Telomere lengths were determined by a flow cytometric fluorescence in situ hybridization assay (FLOW-FISH). RESULTS: Female breast cancer cases (n = 24) had reduced lymphocyte telomere lengths by comparison with healthy controls (n = 20, p < 0.04). However, the average age of healthy controls was less (45.4) than cases (53). When the control group was modified to give a better age match (51.5, n = 13) the reduced telomere length in cases was not significantly different from controls. Lymphocytes from breast cancer cases also showed reduced cell cycle delay (p < 0.001) and increased apoptosis (p < 0.01) following irradiation in vitro at 3 and 5 Gy respectively, compared to healthy controls. Statistical significance was maintained with the improved age matching of groups. Comparison of lymphocytes from breast cancer patients with normal (n = 11) and severe (n = 13) skin reactions to radiotherapy failed to identify differences in telomere length or cellular radiosensitivity in this limited sample. CONCLUSIONS: This study adds to the evidence suggesting a correlation between altered cellular radiosensitivity and breast cancer. However, in the cases investigated, telomere length does not appear to be predictive of acute skin reactions to radiotherapy.
    • Management of hyponatraemia.

      Mittal, Rahul; Sheftel, H; Demssie, Y; Christie Hospital NHS Foundation Trust, Manchester, UK. (2011-02)
      Hyponatraemia (serum sodium level < 135 mmol/litre) is the most common electrolyte abnormality among hospitalized patients. A prevalence rate as high as 15-30% has been reported among patients admitted to acute and intensive care units (Hoorn et al, 2004; Jaber et al, 2006). Evidence suggests an increase in mortality associated with even a mild degree of hyponatraemia (Waikar et al, 2009). Besides its significance as a potential cause of morbidity and mortality, hyponatraemia could also serve as a useful indicator for undiagnosed underlying pathology such as endocrine disorders or malignancy. A systematic approach towards the clinical assessment and interpretation of biochemical abnormalities is vital to facilitate the diagnosis and management of hyponatraemia. The optimal treatment of hyponatraemia should take into account its severity, duration and mode of clinical presentation. Overzealous correction could result in irreversible neurological complications.
    • Management of the lymph nodes in penile cancer.

      Heyns, Chris F; Fleshner, Neil; Sangar, Vijay K; Schlenker, Boris; Yuvaraja, Thyavihally B; Van Poppel, Hendrik; Department of Urology, Stellenbosch University and Tygerberg Hospital, Tygerberg, South Africa. cfh2@sun.ac.za (2010-08)
      A comprehensive literature study was conducted to evaluate the levels of evidence (LEs) in publications on the diagnosis and staging of penile cancer. Recommendations from the available evidence were formulated and discussed by the full panel of the International Consultation on Penile Cancer in November 2008. The final grades of recommendation (GRs) were assigned according to the LE of the relevant publications. The following consensus recommendations were accepted. Fine needle aspiration cytology should be performed in all patients (with ultrasound guidance in those with nonpalpable nodes). If the findings are positive, therapeutic, rather than diagnostic, inguinal lymph node dissection (ILND) can be performed (GR B). Antibiotic treatment for 3-6 weeks before ILND in patients with palpable inguinal nodes is not recommended (GR B). Abdominopelvic computed tomography (CT) and magnetic resonance imaging (MRI) are not useful in patients with nonpalpable nodes. However, they can be used in those with large, palpable inguinal nodes (GR B). The statistical probability of inguinal micrometastases can be estimated using risk group stratification or a risk calculation nomogram (GR B). Surveillance is recommended if the nomogram probability of positive nodes is <0.1 (10%). Surveillance is also recommended if the primary lesion is grade 1, pTis, pTa (verrucous carcinoma), or pT1, with no lymphovascular invasion, and clinically nonpalpable inguinal nodes, but only provided the patient is willing to comply with regular follow-up (GR B). In the presence of factors that impede reliable surveillance (obesity, previous inguinal surgery, or radiotherapy) prophylactic ILND might be a preferable option (GR C). In the intermediate-risk group (nomogram probability .1-.5 [10%-50%] or primary tumor grade 1-2, T1-T2, cN0, no lymphovascular invasion), surveillance is acceptable, provided the patient is informed of the risks and is willing and able to comply. If not, sentinel node biopsy (SNB) or limited (modified) ILND should be performed (GR B). In the high-risk group (nomogram probability >.5 [50%] or primary tumor grade 2-3 or T2-T4 or cN1-N2, or with lymphovascular invasion), bilateral ILND should be performed (GR B). ILND can be performed at the same time as penectomy, instead of 2-6 weeks later (GR C). SNB based on the anatomic position can be performed, provided the patient is willing to accept the potential false-negative rate of /=2 nodes on one side, contralateral limited ILND with frozen section analysis can be performed, with complete ILND if the frozen section analysis findings are positive (GR B). If clinically suspicious inguinal metastases develop during surveillance, complete ILND should be performed on that side only (GR B), and SNB or limited ILND with frozen section analysis on the contralateral side can be considered (GR C). Endoscopic ILND requires additional study to determine the complication and long-term survival rates (GR C). Pelvic lymph node dissection is recommended if >/=2 proven inguinal metastases, grade 3 tumor in the lymph nodes, extranodal extension (ENE), or large (2-4 cm) inguinal nodes are present, or if the femoral (Cloquet's) node is involved (GR C). Performing ILND before pelvic lymph node dissection is preferable, because pelvic lymph node dissection can be avoided in patients with minimal inguinal metastases, thus avoiding the greater risk of chronic lymphedema (GR B). In patients with numerous or large inguinal metastases, CT or MRI should be performed. If grossly enlarged iliac nodes are present, neoadjuvant chemotherapy should be given and the response assessed before proceeding with pelvic lymph node dissection (GR C). Antibiotic treatment should be started before surgery to minimize the risk of wound infection (GR C). Perioperative low-dose heparin to prevent thromboembolic complications can be used, although it might increase lymph leakage (GR C). The skin incision for ILND should be parallel to the inguinal ligament, and sufficient subcutaneous tissue should be preserved to minimize the risk of skin flap necrosis (GR B). Sartorius muscle transposition to cover the femoral vessels can be used in radical ILND (GR C). Closed suction drainage can be used after ILND to prevent fluid accumulation and wound breakdown (GR B). Early mobilization after ILND is recommended, unless a myocutaneous flap has been used (GR B). Elastic stockings or sequential compression devices are advisable to minimize the risk of lymphedema and thromboembolism (GR C). Radiotherapy to the inguinal areas is not recommended in patients without cytologically or histologically proven metastases nor in those with micrometastases, but it can be considered for bulky metastases as neoadjuvant therapy to surgery (GR B). Adjuvant radiotherapy after complete ILND can be considered in patients with multiple or large inguinal metastases or ENE (GR C). Adjuvant chemotherapy after complete ILND can be used instead of radiotherapy in patients with >/=2 inguinal metastases, large nodes, ENE, or pelvic metastases (GR C). Follow-up should be individualized according to the histopathologic features and the management chosen for the primary tumor and inguinal nodes (GR B).
    • Management of unresectable stage III non-small-cell lung cancer with combined-modality therapy: a review of the current literature and recommendations for treatment.

      Bayman, Neil A; Blackhall, Fiona H; Jain, Pooja; Lee, Lip W; Thatcher, Nick; Faivre-Finn, Corinne; Department of Clinical Oncology, Christie Hospital, Manchester, UK. neil.bayman@christie.nhs.uk (2008-03)
      Lung cancer remains the most common cause of cancer deaths in the United Kingdom, and long-term survival from lung cancer has hardly improved over the past 30 years. The benefit of combined-modality therapy with chemotherapy and radiation therapy in improving survival for patients with inoperable non-small-cell lung cancer (NSCLC) was discovered over 10 years ago. In this comprehensive literature review, we discuss the current status of combined-modality therapy for unresectable stage III NSCLC. The efficacy and toxicity of different chemoradiation therapy regimens are presented. The potential role of novel and targeted therapies and radiation dose escalation is also considered. Finally, recommendations are made for the treatment of unresectable stage III NSCLC.
    • Measurement tools for gastrointestinal symptoms in radiation oncology.

      West, Catharine M L; Davidson, Susan E; Academic Department of Radiation Oncology, The University of Manchester, UK. Catharine.West@manchester.ac.uk (2009-03)
      PURPOSE OF REVIEW: To review the use of measurement tools for reporting gastrointestinal toxicity in radiation oncology to highlight recent findings of potential interest to those involved in the treatment of tumors in the pelvis, assessment of survivorship issues or management of bowel effects. RECENT FINDINGS: Multiple measurement tools are being used in radiation oncology studies involving both clinician and patient-reported outcomes. The increasing availability of accurate data on radiation doses and dose-volumes to normal tissues is enabling identification of critical areas where dose should be reduced to minimize organ damage. SUMMARY: Measurement tools for gastrointestinal symptoms are important to highlight therapeutic benefit for the expanding investigations of treatment intensification approaches and methods for toxicity reduction. The increasing use of the CTCAEv3 scales is a step forward, but further research is required to refine the system and improve its ease of use within routine clinical practice.
    • Metastatic bladder cancer: a review of current management.

      Fletcher, Andrew; Choudhury, Ananya; Alam, Nooreen; Department of Palliative and Supportive Care, The Christie NHS Foundation Trust, Wilmslow Road, Manchester M20 4BX, UK. (2011)
      Bladder cancer continues to result in substantial morbidity and mortality for affected individuals. Advances in the management of metastatic bladder cancer have been limited. Chemotherapy with platinum-based regimes remains the mainstay of first-line treatment. Studies investigating alternative regimes have offered no survival advantage. Targeted therapies may offer benefit either as single agent or in combination with chemotherapy. Symptoms due to metastatic bladder cancer impact patients' quality of life, and therefore holistic management is vital. Such management includes radiotherapy, bisphosphonates, and the involvement of specialist palliative care services. This review will discuss the current management for metastatic bladder cancer, future potential treatment modalities, and the evidence to support the management strategies.
    • MRE11 expression is predictive of cause-specific survival following radical radiotherapy for muscle-invasive bladder cancer.

      Choudhury, Ananya; Nelson, L D; Teo, M T W; Chilka, S; Bhattarai, S; Johnston, C F; Elliott, F; Lowery, J; Taylor, C F; Churchman, M; et al. (2010-09-15)
      Radical radiotherapy and surgery achieve similar cure rates in muscle-invasive bladder cancer, but the choice of which treatment would be most beneficial cannot currently be predicted for individual patients. The primary aim of this study was to assess whether expression of any of a panel of DNA damage signaling proteins in tumor samples taken before irradiation could be used as a predictive marker of radiotherapy response, or rather was prognostic. Protein expression of MRE11, RAD50, NBS1, ATM, and H2AX was studied by immunohistochemistry in pretreatment tumor specimens from two cohorts of bladder cancer patients (validation cohort prospectively acquired) treated with radical radiotherapy and one cohort of cystectomy patients. In the radiotherapy test cohort (n = 86), low tumor MRE11 expression was associated with worse cancer-specific survival compared with high expression [43.1% versus 68.7% 3-year cause-specific survival (CSS), P = 0.012] by Kaplan-Meier analysis. This was confirmed in the radiotherapy validation cohort (n = 93; 43.0% versus 71.2%, P = 0.020). However, in the cystectomy cohort (n = 88), MRE11 expression was not associated with cancer-specific survival, commensurate with MRE11 being a predictive marker. High MRE11 expression in the combined radiotherapy cohort had a significantly better cancer-specific survival compared with the high-expression cystectomy cohort (69.9% versus 53.8% 3-year CSS, P = 0.021). In this validated immunohistochemistry study, MRE11 protein expression was shown and confirmed as a predictive factor associated with survival following bladder cancer radiotherapy, justifying its inclusion in subsequent trial designs. MRE11 expression may ultimately allow patient selection for radiotherapy or cystectomy, thus improving overall cure rates.
    • Mucosal melanoma of the head and neck: radiotherapy or surgery?

      Douglas, Catriona Mairi; Malik, Tass; Swindell, Ric; Lorigan, Paul C; Slevin, Nicholas J; Homer, Jarrod J; Department of Head and Neck Surgery, Christie Hospital, Manchester, United Kingdom. (2010-08)
      INTRODUCTION: Head and neck mucosal melanoma (MuM) is rare, comprising < 1% of all melanomas in Western Europe. METHODS: A retrospective analysis of case records of patients treated between 1965 and 2001 was carried out. (Survival outcomes were obtained from the case notes and cancer registry.) The median age of the 68 patients was 63 years (range 29-86 years). Thirty-nine percent were male, and 61% were female. (The minimum follow-up time was 15 months.) The two most common primary sites were the sinonasal complex (65%) and oral cavity (19%). Twenty-one percent of patients presented with metastases (nodal or distant). Fifty-five patients were treated with curative intent: 30 patients with primary radiotherapy and 25 patients with surgery +/- postoperative radiotherapy. RESULTS: The overall survival was 22% at 5 years, and the cancer-specific survival was 32% at 5 years. CONCLUSION: MuM has a poor overall prognosis. Poor prognostic indicators are site at presentation and presentation with metastasis. This series is unique in that a significant proportion of patients were given primary radiotherapy as definitive treatment. Surgery may have advantages, particularly for oral cavity MuM. In contrast to previous reports, definitive radiotherapy is worthy of consideration as curative treatment.

    • A novel imaging technique for fusion of high-quality immobilised MR images of the head and neck with CT scans for radiotherapy target delineation.

      Webster, Gareth J; Kilgallon, J E; Ho, Kean F; Rowbottom, Carl G; Slevin, Nicholas J; Mackay, Ranald I; North Western Medical Physics, Christie Hospital NHS Foundation Trust, Manchester, UK. gareth.webster@physics.cr.man.ac.uk (2009-06)
      Uncertainty and inconsistency are observed in target volume delineation in the head and neck for radiotherapy treatment planning based only on CT imaging. Alternative modalities such as MRI have previously been incorporated into the delineation process to provide additional anatomical information. This work aims to improve on previous studies by combining good image quality with precise patient immobilisation in order to maintain patient position between scans. MR images were acquired using quadrature coils placed over the head and neck while the patient was immobilised in the treatment position using a five-point thermoplastic shell. The MR image and CT images were automatically fused in the Pinnacle treatment planning system using Syntegra software. Image quality, distortion and accuracy of the image registration using patient anatomy were evaluated. Image quality was found to be superior to that acquired using the body coil, while distortion was < 1.0 mm to a radius of 8.7 cm from the scan centre. Image registration accuracy was found to be 2.2 mm (+/- 0.9 mm) and < 3.0 degrees (n = 6). A novel MRI technique that combines good image quality with patient immobilization has been developed and is now in clinical use. The scan duration of approximately 15 min has been well tolerated by all patients.
    • Omitting elective nodal irradiation during thoracic irradiation in limited-stage small cell lung cancer - Evidence from a phase II trial.

      Colaco, Rovel J; Sheikh, Hamid Y; Lorigan, Paul C; Blackhall, Fiona H; Hulse, Paul; Califano, Raffaele; Ashcroft, Linda; Taylor, Paul; Thatcher, Nick; Faivre-Finn, Corinne; et al. (2012-04)
      Omitting elective nodal irradiation (ENI) in limited-stage disease small cell lung cancer (LD-SCLC) is expected to result in smaller radiation fields. We report on data from a randomised phase II trial that omitted ENI in patients receiving concurrent chemo-radiotherapy for LD-SCLC. 38 patients with LD-SCLC were randomised to receive once-daily (66Gy in 33 fractions) or twice-daily (45Gy in 30 fractions) radiotherapy (RT). 3D-conformal RT was given concurrently with cisplatin and etoposide starting with the second cycle of a total of four cycles. The gross tumour volume was defined as primary tumour with involved lymph nodes (nodes ≥1cm in short axis) identifiable with CT imaging. ENI was not used. Six recurrence patterns were identified: recurrence within planning target volume (PTV) only, recurrence within PTV+regional nodal recurrence and/or distant recurrence, isolated nodal recurrence outside PTV, nodal recurrence outside PTV+distant recurrence, distant metastases only and no recurrence. At median follow-up 16.9 months, 31/38 patients were evaluable and 14/31 patients had relapsed. There were no isolated nodal recurrences. Eight patients relapsed with intra-thoracic disease: 2 within PTV only, 4 within PTV and distantly and 2 with nodal recurrence outside PTV plus distant metastases. Rates of grade 3+ acute oesophagitis and pneumonitis in the 31 evaluable patients were 23 and 3% respectively. In our study of LD-SCLC, omitting ENI based on CT imaging was not associated with a high risk of isolated nodal recurrence, although further prospective studies are needed to confirm this. Routine ENI omission will be further evaluated prospectively in the ongoing phase III CONVERT trial (NCT00433563).
