RESUMEN
BACKGROUND: The Nottinghamshire Lymphoma Registry contains the details of all the patients diagnosed with lymphoma (since 1 January 1973) within a defined geographical area with a population of 1.1 million. It was therefore possible to study the outcome of treatment for Hodgkin's disease for three 10-year cohorts (1973-1982, 1983-1992 and 1993-2002).The aims of the study were to compare survival time among the three patient cohorts, to identify prognostic factors and to estimate relative survival. METHODS: A total of 745 patients diagnosed between 1973 and 2002 were analysed for survival. Survivorship was estimated by the Kaplan-Meier method and parametric survival models. An accelerated failure-time regression was used for multivariate analysis. RESULTS: Overall, patients were observed for 9.8 (0.3-34.82) years (median(range)), on average. One, five and fifteen-year disease-specific survival was found to be 87% (85-90%), 77% (74-80%) and 70% (67-74%), respectively. For those for diagnosed between 1973 and 1982, the 15-year survival was found to be 57%; for 1983-1992, it was 74% and for 1993-2002, it was 83% (P<0.001). The difference remained significant after adjusting for prognostic factors. The actuarial risk of developing a second malignancy at 20 years was for the 1973-1982 cohort, 12.4%, and for the 1983-1992 cohort, 18.8%. CONCLUSION: Treatment advances and effective management of toxicities of treatment over time, have resulted in a significantly longer survival for patients with Hodgkin's disease diagnosed within a defined population.

BACKGROUND: Primary cutaneous B-cell lymphomas (PCBCL), with the exception of large B-cell lymphoma of leg type and intravascular large B-cell lymphoma, are associated with an excellent prognosis. These lymphomas have become much better understood in recent years leading to the publication in 2005 of the World Health Organization-European Organisation for Research and Treatment of Cancer classification. OBJECTIVES: To determine the relative frequency of occurrence of subtypes of PCBCL in a defined population, and the survival of patients with these subtypes. METHODS: During the period 1987-2009, 61 consecutive patients with PCBCL were identified from the Nottingham Lymphoma Registry (population 1·1 million). After histological review, the number of patients with each subtype was as follows: marginal zone, 18; follicle centre, 14; diffuse large B cell, leg type, 16; diffuse large B cell, other sites, 12; and intravascular large B cell, one. RESULTS: The 5- and 10-year lymphoma-specific survival for patients with marginal zone lymphoma was 100%. The only patient with intravascular large B-cell lymphoma died from widespread disease in spite of chemotherapy. The 4-year lymphoma-specific survival for follicle centre cell lymphoma was 90%. Patients with the other subtypes had the following 5-year lymphoma-specific survival rates: diffuse large B cell, leg type, 61% and diffuse large B cell, other, 40%. The median age at diagnosis for patients with diffuse large B-cell lymphoma, leg type was 82 years and as a consequence the 5-year overall survival was only 15%. There was a 3·4-fold increase in the incidence of PCBCL from the period 1987-1997 to the period 1998-2009. CONCLUSIONS: PCBCL is a rare disease (incidence around three per million population per year). It is, in our view, essential that it is diagnosed by a pathologist with an interest in cutaneous lymphoma and that the very different prognosis of the individual subtypes is appreciated by the treating clinician.

BACKGROUND: The MAGIC trial demonstrated the perioperative regimen of Epirubicin (E), Cisplatin (C) and 5-Fluorouracil (F) to have an overall survival benefit for patients with gastro-esophageal adenocarcinomas. We present our experience of the peri-operative regimen of ECF/ECX(X = Capecitabine) in operable gastro-esophageal adenocarcinoma. METHODS: Analysis of retrospective data of patients treated with MAGIC style therapy between May 2006 and August 2008 with potentially operable gastro-esophageal adenocarcinoma. RESULTS: One hundred patients underwent peri-operative chemotherapy according to the MAGIC protocol. Median age was 66 years, with 39% above the age of 70 years. The tumours were evenly distributed between the lower esophagus, gastro-esophageal junction and stomach. Seventy-nine percent completed all pre-operative cycles of chemotherapy and 81% proceeded to surgery, whilst 24% did not receive curative surgery. The median survival on an intention to treat analysis is 31.7 months from diagnosis. The median survival of patients who underwent resection has not yet been reached after a median follow-up of 41.4 months. CONCLUSION: Our patient population is older than the patients in the MAGIC trial (age 66 years vs. 62 years) with a much higher proportion of esophageal and GEJ tumours. Overall, curative resection rate was comparable to the MAGIC trial. Overall survival is superior to that found in the MAGIC trial.

AIMS: To determine tumour regression (volume-halving time) obtained after chemo/radiotherapy, and thereby the ideal interval between the start of treatment and surgery in order to obtain a high rate of complete response. MATERIALS AND METHODS: In total, 106 patients with cT3,4 rectal cancer who received preoperative radiotherapy alone or concurrently with capecitabine chemotherapy at Nottingham City Hospital, UK were studied. The rectal tumour volume visible on the computed tomography planning scan was compared with the residual pathological volume and the tumour volume-halving time calculated. The radiotherapy response was graded according to the Mandard system. RESULTS: Fifty-three patients had radiotherapy alone, with 53 patients having concurrent chemoradiotherapy. The median tumour volume-halving time was found to be 14 days and not influenced by the addition of chemotherapy. The Mandard score, the interval from the start of treatment to surgery and the tumour volume-halving time were statistically associated with tumour regression. The median tumour volume in our series of 54 cm(3) would require an interval of 20 weeks after the start of treatment to surgery to regress to <0.1 cm(3) (10 volume-halving times; 140 days). CONCLUSIONS: The initial tumour volume and median volume-halving time provide the best estimates for determining the optimum length of interval between the completion of preoperative chemo/radiotherapy and surgery in locally advanced rectal cancer.

PURPOSE: The aim of this study is to determine overall survival, disease-specific survival and stoma-free survival after treatment of squamous cell carcinoma of the anus with chemoradiotherapy followed by brachytherapy or electron boost in a recent cohort of patients. METHODS: Fifty-two patients (median age 62 years) were treated with radical chemoradiotherapy (mitomycin C, infusional 5-fluorouracil concurrently with conformal radical radiotherapy 45 Gy in 25 fractions over 5 weeks) followed by a radiotherapy boost between 1 December 2000 and 30 April 2011. Follow-up was to 30 November 2014. Thirty-six patients received a boost (15-20 Gy) over 2 days with 192Ir needle brachytherapy for anal canal tumours, and 16 patients received electron beam therapy (20 Gy in 10 fractions in 2 weeks) for anal margin tumours. A defunctioning stoma was only created prior to chemoradiotherapy for fistula or severe anal pain. RESULTS: The overall survival for the 36 patients treated with chemoradiotherapy followed by brachytherapy was 75 % (95 % CI, 61-89) at 5 years, the disease-specific survival was 91 % (95 % CI, 81-101 %), and the stoma-free survival was 97 % (95 % CI, 91-103 %) all at 5 years. For the 16 patients treated with an electron boost for anal margin tumours, the 5-year overall survival, disease-specific survival and stoma-free survival were 68 % (95 % CI, 44-92 %), 78 % (95 % CI, 56-100 %) and 80 % (95 % CI, 60-100 %), respectively. CONCLUSIONS: A very low stoma formation rate can be obtained with radical chemoradiotherapy followed by a brachytherapy boost for squamous cell carcinoma of the anal canal but not with an electron boost for anal margin tumours.

BACKGROUND: Individuals with metabolically healthy obesity (MHO) do not have the metabolic complications usually associated with obesity. OBJECTIVE: To examine whether youth adiposity, or change in adiposity from youth to adulthood, predicts MHO 20 years later. METHODS: A national sample of 2410 Australian participants had height, weight and waist circumference (WC) measured in 1985 (7-15 years old) and 2004-2006 (26-36 years old). A fasting blood sample was taken in 2004-2006. MHO was defined as body mass index (BMI) ≥30 kg m(-2) , normal fasting glucose (<5.6 mmol L(-1) ), triglycerides (<1.695 mmol L(-1) ), high-density lipoprotein-cholesterol (>1.036 mmol L(-1) men, > 1.295 mmol L(-1) women), blood pressure (<130/85 mmHg) and no medication for these conditions. Relative risks (RR) were calculated using log binomial regression and expressed per unit of youth BMI (or WC) z-score or change in BMI (or WC) z-score from youth to adulthood, adjusted for sex and youth age. RESULTS: In total 323 individuals were obese at follow-up, 79 (24.5%) were MHO. Adult MHO was not associated with youth BMI (RR: 1.00, 95%CI: 0.85-1.19) or WC (RR: 0.93, 95%CI: 0.79-1.11). Individuals were less likely to be MHO if they had larger increases in BMI (BMI RR: 0.74, 95%CI: 0.57-0.97) or WC (RR: 0.70, 95%CI: 0.55-0.90) from youth to adulthood. CONCLUSIONS: Change in adiposity from youth to adulthood predicted adult MHO better than youth adiposity alone.

PURPOSE: To assess the efficacy and toxicity of vinblastine, bleomycin, and methotrexate (VBM) chemotherapy with involved-field radiotherapy in clinical stage IA and IIA Hodgkin's disease. PATIENTS AND METHODS: Thirty eligible patients with clinical stage IA or IIA Hodgkin's disease, at intermediate risk of relapse, were enrolled into a prospective multicenter pilot study. They received two cycles of VBM chemotherapy, followed by involved-field radiotherapy and then four further cycles of VBM. The median follow-up duration from the start of treatment is 30 months. RESULTS: All 26 patients with assessable disease showed an objective response after two cycles of VBM (nine complete responses, 17 partial responses). By the completion of treatment, 27 patients were in complete remission; two had stable residual masses, which have not progressed at 26 and 34 months of follow-up; and one patient who died of treatment-related sepsis was in complete remission at that time. Two relapses have occurred, 19 and 28 months after starting VBM. Cough and dyspnea developed in 14 of 30 patients, and were associated with impairment of pulmonary function tests. Three episodes of neutropenic sepsis were recorded. CONCLUSION: VBM with involved-field radiotherapy is an effective treatment for early Hodgkin's disease. However, the associated toxicity, both pulmonary and hematologic, is severe, making the regimen unsuitable for routine use.

PURPOSE: To assess the effect of a reduced dose of radiotherapy (RT) in patients with primary CNS lymphoma (PCNSL) responding to the cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD)/carmustine, vincristine, methotrexate, and cytarabine (BVAM) regimen. PATIENTS AND METHODS: Patients received one cycle of CHOD and two of BVAM. In the first trial, all 31 patients received 45-Gy whole-brain RT (CHOD/BVAM I). In the second, with 26 patients, RT dose was reduced to 30.6 Gy if there was a complete response (CR) after chemotherapy (CHOD/BVAM II). RESULTS: Age, performance status, and chemotherapy received were similar in both protocols. CR rate at the end of all treatment was 68% for CHOD/BVAM I and 77% and for CHOD/BVAM II. Treatment modality was the only predictor of relapse, with 3-year relapse risks of 29% and 70% for CHOD/BVAM I and II, respectively. This was specifically important in the 25 patients less than 60 years old (3-year relapse risk, 25% v 83%; P =.01). The 5-year overall survival (OS) was 36%. Age (< 60 v > or = 60 years) was the only predictor for OS in the multivariate analysis (relative risk, 2.1; 95% confidence interval, 1.4 to 2.8). RT dose was the only predictor of OS in patients younger than 60 years old who achieved CR at the end of all treatment (3-year OS, 92% v 60% for patients receiving 45 or 30.6 Gy, respectively; P =.04). CONCLUSION: Reduction of the RT dose from 45 Gy to 30.6 Gy in patients younger than 60 years old with PCNSL who achieved CR resulted in an increased risk of relapse and lower OS.

PURPOSE: To assess whether chemotherapy that includes drugs that cross the blood-brain barrier improves survival in primary CNS non-Hodgkin's lymphoma (PCNSL) when combined with radiotherapy. PATIENTS AND METHODS: Thirty-four patients, with no evidence of human immunodeficiency virus type 1 (HIV-1) infection, were treated with the related chemotherapy regimens of carmustine (BCNU), vincristine, cytarabine, and methotrexate (BVAM; 12 patients), cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD)/BVAM (17 patients) and intensified CHOD/BVAM (five patients) between 1986 and 1994. The median age was 60 years (range, 16 to 73) and 47% had a performance status of 3 or 4 (Eastern Cooperative Oncology Group [ECOG]/World Health Organization [WHO]). Ten patients were treated with BVAM chemotherapy between 1986 and 1989, and subsequently 17 patients were treated with CHOD/BVAM (cytarabine 3 g/m2). Twenty of these 27 patients received whole-brain radiotherapy (craniospinal in four). RESULTS: The complete response (CR) rate at the completion of chemotherapy was 63% for BVAM and 67% for CHOD/BVAM; more neutropenia occurred with CHOD/BVAM. The 5-year actuarial probability of survival of all 34 patients was 33% (95% confidence interval [CI], 14% to 52%), with so far only one recurrence after 2 years. Using multivariate analysis, age (P = .0005) and number of tumors at diagnosis (P = .0358) were prognostic factors. All five patients aged > or = 70 years died during or shortly after chemotherapy. Performance status was not an independent variable. CONCLUSION: The BVAM or CHOD/BVAM regimens can be delivered despite neutropenia without significant treatment delay or dose reduction in patients less than 70 years of age. Further intensification of this type of chemotherapy is probably not possible with patients of this age, many of whom have a poor performance status.

PURPOSE: A pilot study to validate the use of CD34+ selection (Ceprate SC) of blood stem-cell collection in patients with advanced follicular lymphoma receiving myeloablative chemoradiotherapy. PATIENTS AND METHODS: Seventeen patients were entered onto the protocol. Thirteen of 17 patients have undergone transplantation; the median age is 42.5 years (range, 33 to 51), seven of 13 are stage IVB, two stage IVA, three stage IIIB, and one stage IIB. All except two patients were treated after first or subsequent relapses after receiving cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy to achieve a good partial (six of 13) or complete (seven of 13) response before stem-cell mobilization with cyclophosphamide 3 g/m2 and filgrastim 300 microg once daily. RESULTS: Eleven of 13 patients had a detectable t(14;18) by nested polymerase chain reaction (PCR). Median CD34+ count before selection was 2.9 x 10(6)/kg (range, 1.17 to 11.3) and after CD34+ selection was 1.54 x 10(6)/kg (range, 0.88 to 7.6) with a median CD34+ yield of 62.4% (range, 17% to 95%) and purity of 60% (range, 39.3% to 73%). Of the 11 patients known to have t(14;18), 10 had PCR-detectable contamination of stem-cell harvests that became PCR negative in six of the 10 after CD34+ selection. Engraftment was rapid with a median day to absolute neutrophil count (ANC) greater than 0.5 x 10(9)/L of 13 days (range, 11 to 21) and platelet count greater than 20 x 10(9)/L of 14 days (range, 10 to 44). With a median follow-up duration of 15 months, three patients have remained persistently PCR-positive, two of whom received PCR-positive stem cells. Two have relapsed. Of the seven patients who received PCR-negative stem cells, five have had no PCR-detectable disease in posttransplant bone marrow samples. CONCLUSION: Longer follow-up duration is required to determine the significance of these findings, but we have confirmed the feasibility of CD34+ selected cells to deplete peripheral-blood stem cells of tumor cells from patients undergoing high-dose therapy for follicular lymphoma.

PURPOSE: Chemotherapy for non-small-cell lung cancer (NSCLC) remains controversial. We describe the two largest reported, randomized, parallel trials designed to determine whether the addition of chemotherapy influences duration and quality of life in localized, unresectable (mitomycin, ifosfamide, cisplatin [MIC]1 trial) and extensive (MIC2 trial) disease. PATIENTS AND METHODS: Ambulatory patients with NSCLC, aged 75 years or younger, with localized disease, were randomized in MIC1 to receive up to four cycles of chemotherapy (CT: mitomycin 6 mg/m(2), ifosfamide 3 g/m(2), and cisplatin 50 mg/m(2)) every 21 days, followed by radical radiotherapy (CT + RT) or radiotherapy (RT) alone. Extensive-stage patients were randomized in MIC2 to identical chemotherapy plus palliative care (CT + PC) or palliative care (PC) alone. Short-term change in quality of life (QOL) was assessed in a subgroup of patients. Data from the two trials were combined to allow multivariate and stratified survival analyses. RESULTS: Seven hundred ninety-seven eligible patients were randomized, 446 in MIC1 and 351 in MIC2. MIC CT improved survival in both trials (significantly in MIC2). The median survival time in MIC1 was 11.7 months (CT + RT) versus 9.7 months (RT alone) (P =.14); whereas in MIC2, median survival time was 6.7 months (CT + PC) compared with 4. 8 months (PC alone) (P =.03). QOL, assessed in 134 patients from start of trial to week 6, showed improvement with chemotherapy and deterioration with standard treatment. In the combined analysis of 797 randomized patients, the positive effect of MIC on survival was significant overall (P =.01) and after adjusting for prognostic factors (P =.01). CONCLUSION: MIC chemotherapy prolongs survival in unresectable NSCLC without compromising QOL.

PURPOSE: Mantle-cell lymphoma (MCL), immunocytoma (IMC), and small B-cell lymphocytic lymphoma (SLL) are B-cell malignancies that express CD20 and are incurable with standard therapy. A multicenter phase II study was conducted to assess the toxicity and the overall response rates (RR) and complete response (CR) rates to rituximab (chimeric anti-CD20 monoclonal antibody). PATIENTS AND METHODS: Between January 1997 and January 1998, 131 patients with newly diagnosed MCL (MCL1; n = 34) and previously treated MCL (MCL2; n = 40), IMC (n = 28), and SLL (n = 29) received rituximab 375 mg/m(2)/wk for 4 weeks via intravenous infusion. Restaging studies were performed 1 and 2 months after treatment. An analysis of the duration of response was conducted in December 1998. RESULTS: Eleven patients were unassessable, including one who died of splenic rupture after the first infusion. The RR among the 120 assessable patients was 30% (36 of 120 patients). The RR by histology was as follows: MCL1, 38%; MCL2, 37%; IMC, 28%; and SLL, 14%. Ten patients, all with MCL, achieved CR. The median duration of response in MCL was 1.2 years. Immediate side effects were common and usually responded to adjustments in the infusion rate. There were 31 episodes of infection after treatment; most cases were mild. Cardiac arrhythmia and ophthalmologic side effects occurred in 10 and nine patients, respectively, including one case of severe loss of visual acuity. CONCLUSION: Single-agent rituximab has moderate activity in MCL and IMC but only limited activity in SLL. The duration of response in MCL was similar to that previously reported in follicular lymphoma. Its use in combination with cytotoxic chemotherapy to increase the CR rate is warranted in MCL and IMC.

20 patients with ovarian carcinoma whose disease had relapsed (1-42 months, median 4 months) after showing either response or stable disease to carboplatin, were treated with ifosfamide (5 g/m2 intravenously over 24 h, day 1) and carboplatin (200 mg/m2 intravenously day 2) as second-line treatment. The mean number of treatment cycles was 3.5 (range 1-6). The major toxicities were thrombocytopenia (WHO grade 3/4, 25%), neutropenia (WHO grade 3/4, 40%) and encephalopathy (WHO grade 3/4, 15%). Overall response rate was 15% [complete response, 0; partial response, 3 (15%); no change, 5 (25%) and progressive disease, 12 (60%)]. The median survival from the date of second-line treatment was 7 months. This combination offers no advantage over either agent used alone.

During the period 1 January 1988 to 31 July 1991, 74 patients were seen with intermediate- or high-grade non-Hodgkin's lymphoma who were aged 70 years or over. Of these 74 patients, 20 were treated with radiotherapy alone, and 46 were judged as suitable for treatment with the chemotherapy regime MCOP (mitoxantrone, cyclophosphamide, vincristine and prednisolone). Involved field radiotherapy (35-40 Gy in 20 fractions over 4 weeks) was given to 14 of the 21 patients with stage IA and IIA disease, and 6 of the 25 patients with stage III and IV disease after completion of chemotherapy. The complete response rate was 63% at the completion of all treatment (6 months), and 39% at 12 months. There were no treatment-related deaths, and the 3-year cause-specific survival was 26% (overall survival 21%). For patients aged 70-75 years, the 3-year cause-specific survival was 34% in comparison to 17% for those patients aged 76-93 years. The chemotherapy was well tolerated by those patients aged 70 years and over, 70% of the patients did not vomit and no patients had significant vincristine neuropathy. There were only four infections associated with neutropenia. All patients completing six cycles had moderate, patchy alopecia. This MCOP regime is suitable for patients aged 70 years and over with intermediate- and high-grade non-Hodgkin's lymphoma. The survival of patients is comparable to that obtained with CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) with less apparent toxicity.

Between 1973 and 1993, 529 patients aged 15 years and over with Hodgkin's disease (HD) were entered into a lymphoma registry. Twenty-eight cases (1 only diagnosed at autopsy) of histologically proven HD in patients aged 70 years or older were identified. The distribution of sex, 'B' symptoms, histology and stage was not significantly different from that of younger patients, except for the fact that there were no patients aged 70 years or older with lymphocyte predominant HD. Nineteen patients were treated radically, 5 patients palliatively and 4 patients received no radiotherapy or chemotherapy. Three of the 14 patients treated with chemotherapy achieved the planned dose intensity. The cause-specific 5-year survival was 75% for patients aged 15-69 years and 28% for patients aged 70 years and over (logrank chi(2) = 43.7, P < 0.00001). The younger and older groups treated with radical intent had complete response rates of 97% and 74%, respectively (logrank chi(2) = 17.91, P < 0.00001) and relapse rates at 5 years of 27% and 56%, respectively (logrank chi(2) = 4.86, P = 0.0275). The main reason for the poorer prognosis of patients aged 70 years and over was the increasing difficulty of chemotherapy delivery associated with advancing age.

The results of treatment of 47 adults with medulloblastoma are reviewed. For those treated with ortho-voltage radiotherapy between 1952 and 1963 the actuarial 5- and 10-year survival rates were 38% and 23%, respectively. Of those treated with megavoltage radiotherapy between 1964 and 1981, the corresponding 5- and 10-year survival rates were 59% and 53%, respectively. Of patients treated with megavoltage radiotherapy and adjuvant chemotherapy between 1971 and 1981, 76% were alive at 5 years and also at 10 years. Treatment factors associated with an increased survival were complete or subtotal resection of the primary tumor, as opposed to partial removal, a radiation dose to the posterior fossa of 55 Gy or more and the administration of adjuvant chemotherapy. Neither the quality of life, nor the fertility of the surviving patients, have been impaired by the treatment. Six patients (13%) developed metastatic disease outside the central nervous system.

Measurements were made of the exponential regression of cervical nodes from 44 patients with squamous carcinoma of the head and neck and of 20 salivary gland tumors treated with neutrons (7.5 MeV). In 80% of patients, the tumor regressed exponentially from the first day of treatment; in 20% of patients there was an initial shoulder followed by exponential regression. The volume-halving times were calculated and found to vary widely for each histological type. There was no correlation of the volume-halving time either with the differentiation of the squamous carcinomas or with the initial tumor volume. The mean volume-halving time for squamous carcinoma of the head and neck was 20.8 days; for malignant pleomorphic adenomas of the parotid gland the mean volume-halving time was 122.6 days.

PURPOSE: To determine the radiation tolerance of the lens of the eye and the incidence of radiation-induced lens changes in patients treated by fractionated supervoltage radiation therapy for orbital tumors. METHODS: Forty patients treated for orbital lymphoma and pseudotumour with tumour doses of 20-40 Gy were studied. The lens was partly shielded using lead cylinders in most cases. The dose to the germinative zone of the lens was estimated by measurements in a tissue equivalent phantom using both film densitometry and thermoluminescent dosimetry. Ophthalmological examination was performed at 6 monthly intervals after treatment. RESULTS: The lead shield was found to reduce the dose to the germinative zone of the lens to between 36-50% of the tumor dose for Cobalt beam therapy, and to between 11-18% for 5 MeV x-rays. Consequently, the len doses were in the range 4.5-30 Gy in 10-20 fractions. Lens opacities first appeared from between 3 and 9 years after irradiation. Impairment of visual acuity ensued in 74% of the patients who developed lens opacities. The incidence of lens changes was strongly dose-related. None was seen after doses of 5 Gy or lower, whereas doses of 16.5 Gy or higher were all followed by lens opacities which impaired visual acuity. The largest number of patients received a maximum lens dose of 15 Gy; in this group the actuarial incidence of lens opacities at 8 years was 57% with visual impairment in 38%. CONCLUSION: The adult lens can tolerate a total dose of 5 Gy during a fractionated course of supervoltage radiation therapy without showing any changes. Doses of 16.5 Gy or higher will almost invariably lead to visual impairment. The dose which causes a 50% probability of visual impairment is approximately 15 Gy.

Ninety-three patients with primary intracranial ependymoma were treated at the Royal Marsden Hospital, between 1952 and 1988, with postoperative radiotherapy. The survival probability at 5, 10, and 15 years was 51%, 42% and 31%, respectively, and the corresponding progression free survival (PFS) probability, 41%, 38%, and 30%. Tumor grade was the single most important prognostic factor for survival and PFS with gender of lesser prognostic significance. Treatment parameters were stratified for grade. In patients with low grade tumors survival and PFS were better following complete macroscopic excision compared to incomplete surgery. The extent of resection had no significant influence on survival or PFS in patients with high grade tumors. Extent of irradiation did not influence PFS, irrespective of tumor grade, while patients with high grade tumors had marginally better survival following extensive irradiation compared to more limited radiotherapy. The main problem in the treatment of ependymoma remains local progression which was the cause of death in all but two patients. New treatment strategies should focus on improvement of local control, especially in incompletely resected low grade tumors and all high grade tumors. The use of spinal irradiation is unlikely to significantly improve treatment results.
