Penile brachytherapy-Retrospective review of a single institution.

PURPOSE: To analyze the results of exclusive brachytherapy (BT) to treat patients with penile squamous cell carcinoma confined to the glans or prepuce. METHODS AND MATERIALS: Retrospective analysis of 25 patients treated for T1-T2 penile cancer with exclusive interstitial BT between July 1989 and March 2014 at our institution. RESULTS: Median followup was 9.2 years (range, 0-19). The mean patient age was 65.3 years (range, 51-80). Most patients underwent exclusive low-dose-rate BT (56%; n = 14) or pulsed-dose-rate BT (40%; n = 10). Only 1 patient received high-dose-rate BT (4%). The median prescribed dose was 60 Gy. Eight patients died during follow-up because of systemic progression (one case) and other intercurrent causes (seven cases). Two failures were recorded (one local and one regional), both at 4 months after BT. The remaining patients continued follow-up at our institution and maintained response. Two patients underwent partial phallectomy for toxicity. At the time of this report, 12 of the 25 patients are alive and free of disease. The most common late toxicities were telangiectasia, urethral stenosis, and atrophy, in 48%, 43%, and 17.4% of patients, respectively. CONCLUSIONS: BT with low dose rate/pulsed dose rate provides excellent locoregional control for small (≤4 cm) T1-T2 squamous cell carcinoma of the penile glans.

Patterns of care for brachytherapy in Europe: updated results for Spain.

OBJECTIVE: The aim of this follow-up pattern of care study was to evaluate current clinical practices, staffing and equipment, and to compare these results to a study performed 5 years previously. MATERIALS AND METHODS: This descriptive, pattern of care study was carried out via an online questionnaire. The survey was sent to a total of 95 cancer care centres in Spain. RESULTS: Seventy-three centres (76.8%) responded to the survey. More than half (57.5%) of responding centres offered brachytherapy (BT). A mean of 120 patients/centre were treated by BT in 2007. The most common localisations were the endometrium (29.6% of cases), prostate (29.6%), cervix uteri (14.6%), breast (12.6%), head and neck (3.6%) and vagina (2.5%). Other sites accounted for less than 2% of cases each. Most centres that offered BT (33/40 = 82.5%) were equipped with a dedicated BT operating room. The most commonly reported dosimetric method was CT dosimetry (31 of 40 centres = 77.5%), followed by plain film (30/40 = 75%), ultrasound (26/40 = 65%), MRI (8/40 = 20%), in vivo (7/40 = 17.5%) and PET-CT (5/40 = 12.5%) dosimetry. CONCLUSION: The three most common treatment sites (gynaecological, breast and prostate) remain unchanged from 2002, with prostate treatments showing large increase. Advanced dosimetric techniques (MRI, PET-CT and CT-dosimetry) continue to gain adherents. Some centres treat small numbers of patients, a finding that deserves more attention in terms of cost and quality of care. Although BT remains strong in Spain, it could be further strengthened by making modern dosimetric techniques and treatments more widely available.

Overview of brachytherapy resources in Latin America: a patterns-of-care survey.

PURPOSE: Relatively little is known about available resources and patterns of practice for brachytherapy (BT) in Latin America. To rectify this situation, we performed a patterns-of-care survey whose aim was to assess the human and material resources available for BT in Latin America and document current clinical practices. METHODS AND MATERIALS: A total of 392 radiotherapy (RT) centers located in 17 Latin American countries were asked to complete an online survey that included detailed questions about BT practices, facilities, and staffing. The study was coordinated through central offices located in Spain and Peru. National coordinators were appointed to manage the survey in each individual country. RESULTS: Overall, 77 of the 392 institutions (20%) completed the questionnaire. Of the 14 countries with at least one response, the participation rate was 35% (77 of 223 RT centers). The average number of patients (RT+BT) per center was 917. The mean number of BT patients per center increased by 46% (from 105 to 153 patients) from 2002 to 2007. Gynecologic localizations (endometrium, cervix, and vagina) accounted for 95% of treatments, and the uterine cervix was the most common tumor site (75% of all treatments). CONCLUSIONS: In Latin America, BT is most commonly used to treat gynecologic tumors, particularly of the cervix. Relatively few interventions were performed for breast and prostate. This was the first study of its kind in this region and should be repeated periodically.

Patterns of care for brachytherapy in Europe: updated results.

OBJECTIVE: This descriptive survey evaluated brachytherapy (BT) practices and resources in the European area. This was a follow-up study to the original patterns of care for brachytherapy in Europe (PCBE). MATERIALS AND METHODS: A total of 1121 radiotherapy (RT) centres from 41 countries were asked to complete an online questionnaire on BT practices and resources. Countries with fewer than 50% of centres responding were excluded. Participating countries were divided into three groups based on gross domestic product (GDP); group I contained the countries with the highest GDP. RESULTS: The response rate was 56% (633/1121 centres) with 30/41 countries (73%) meeting the inclusion criteria. Sixty percent of reporting centres provided brachytherapy. Responding centres treated an average of 138 (±10, 1 SD) patients with BT; in group I, the mean was 110/centre, an increase of 18% from 2002. CT-dosimetry increased to 61% of centres vs. 33% in 2002. HDR (high-dose rate) BT was the most commonly reported technique (65% of centres). Most BT interventions were for gynaecological tumors (59% of all cases), followed by prostate (17%), breast (9%), lung/bronchus (3%), and esophagus tumors(2%). CONCLUSION: Gynaecological BT remains the most common application, although both prostate and breast BT have increased. CT-based dosimetry has become increasingly common since 2002. The use of HDR and PDR (pulsed-dose rate) techniques has increased markedly, while both LDR and MDR (medium-dose rate) have declined.

Patterns of care study for brachytherapy: results of the questionnaire for the years 2002 and 2007 in The Netherlands.

PURPOSE: The goal of the ESTRO Patterns of Care study for Brachytherapy in Europe (PCBE) 2002 was to develop an aid to analyse brachytherapy practices. A 2nd version of the PCB questionnaire was created for 2007. Data over 2007 were collected at the radiotherapy institutions in The Netherlands and compared with those from 2002. The aim of this study is to describe national brachytherapy practices, to demonstrate trends, and to provide data for rational health care planning. MATERIAL AND METHODS: Data were collected using a web-based questionnaire. For each centre, a local coordinator, responsible for coordinating the questionnaires and support of the further analysis was assigned. Data from the national cancer incidence registry was used for comparison with the data from the 21 Dutch departments. RESULTS: There was a decrease in low-dose rate equipment in parallel to an increase in both pulsed-dose rate and high-dose rate equipment. The use of 3D CT and MR based imaging techniques showed a slow rise. The most common clinical procedures were for prostate, gynaecological, and oesophageal tumours. A large increase (146%) in permanent implant prostate applications using 125I seeds was observed. The numbers of oesophageal and gynaecological treatments remained stable. There is concern on the low numbers of cases treated in some institutions for a few complex treatment sites. For head and neck, anal canal, paediatrics, bladder and eye interventions it ranged from 3-20 patients per year per institution. CONCLUSIONS: The increase in number of patient treated with brachytherapy is in accordance with the increases in cancer incidence. The percentage of all radiotherapy patients treated with brachytherapy (approximately 5%) remained stable. The survey identified certain trends in resources and techniques, as well as areas of expected improvement and possible gain in clinical outcome. Data reported from this survey can be used for further planning of resources, facilities and concentration of a low-volume specialised and complex treatments.

Brachytherapy in the United Kingdom and Spain: a subset analysis of a European pattern of care survey.

PURPOSE: The aim of this pattern of care survey was to provide an overview of brachytherapy resources and practices in the United Kingdom (UK) and Spain and to identify differences that may be relevant to health-care delivery and planning. METHODS AND MATERIALS: Both countries formed part of a larger survey of European radiation oncology centres carried out in 2002. The present study includes only data from centres that perform brachytherapy and completed the questionnaire. RESULTS: Between 1997 and 2002, the number of hospitals offering brachytherapy increased by 10.2% in the UK and 21.4% in Spain. The mean number of radiotherapy patients per centre was significantly higher in the UK (2811 patients) than in Spain (1203). Gynaecological tumours accounted for most procedures (59.7% in Spain and 60.8% in the UK), followed by prostate cancer in the UK (16.7%) and breast cancer in Spain (15.5%). Significantly more procedures for breast cancer were performed in Spain (19.7 patients/centre) than in the UK (0.4 patients/centre). A significantly higher percentage of radiation oncologists in Spain performed brachytherapy, dedicating more time to brachytherapy-related work (22.2 h/week) than their colleagues in the UK (6.7 h/week). CONCLUSIONS: Brachytherapy resources and patterns of care are similar in both countries, although several notable differences exist. Radiation oncologists in Spain dedicate significantly more time to brachytherapy. Compared to the UK, brachytherapy is used more frequently in Spain as a boost in breast cancer treatments. Both countries perform more brachytherapy procedures for prostate cancer than the European average.
