RESUMO

PURPOSE: To evaluate the preliminary results of the use of 68 Gy EQD2(α/ß=3 Gy) as a dose limit to the lowest dose in the most exposed 2 cm3 of the vagina in order to reduce G2 late vaginal problems in postoperative endometrial carcinoma (EC). METHODS: From November 2016 to October 2019, 69 postoperative EC patients receiving vaginal brachytherapy (VBT) ± external beam radiotherapy (EBRT) were prospectively analyzed. The median EBRT dose was 45 Gy (range: 44-50.4 Gy), 1.8-2 Gy/day, 5 fractions(Fr)/week. VBT was administered with the following schedule: 1Fr of 7 Gy after EBRT and 2 daily Fr × 7.5 Gy in exclusive VBT. The dose was prescribed at 0.5 cm from the applicator surface with an active length of 2.5 cm; 56 patients were treated with vaginal cylinders (49-3.5 cm, 6-3 cm, and 1-2.5 cm) and 13 with the colpostat technique. The overall VBT dose was adjusted to meet the vaginal restriction of < 68 Gy EQD2(α/ß=3 Gy) at 2 cm3. Late toxicity was prospectively assessed using RTOG scores for bladder and rectum, and the objective LENT-SOMA criteria for vagina. RESULTS: With a median follow-up of 31.0 months, no vaginal-cuff recurrences were found. Late toxicity: only 1G1(1.4%) rectal toxicity; 21G1(30.4%) and 3G2(4.3%) vaginal complications. Only one (1.4%) of 3 G2 manifested as vaginal shortening. CONCLUSIONS: In postoperative EC patients treated with VBT, only one developed G2 vaginal stenosis with the use of 68 Gy EQD2(α/ß=3 Gy) as a dose constraint. These preliminary results seem to indicate the value of this dose limit for reducing G2 vaginal stenosis. Nonetheless, these findings should be confirmed in a larger number of patients with longer follow-up.

RESUMO

Infertility is one of the main sequelae of cancer and its treatment in both children and adults of reproductive age. It is, therefore, essential that oncologists and haematologists provide adequate information about the risk of infertility and the possibilities for its preservation before starting treatment. Although many international clinical guidelines address this issue, this document is the first Spanish multidisciplinary guideline in paediatric and adult oncological patients. Experts from the Spanish Society of Medical Oncology, the Spanish Fertility Society, the Spanish Society of Haematology and Haemotherapy, the Spanish Society of Paediatric Haematology and Oncology and the Spanish Society of Radiation Oncology have collaborated to develop a multidisciplinary consensus.

RESUMO

OBJECTIVE: The aim of our systematic review was to assess the role of interventional radiotherapy (IRT, brachytherapy) in the management of primary and/or recurrent vulvar carcinoma. EVIDENCE ACQUISITION: A systematic research using PubMed, Scopus and Cochrane library was performed. ClinicalTrials.gov was searched for ongoing or recently completed trials, and PROSPERO was searched for ongoing or recently completed systematic reviews. Only full-text English-language articles related to IRT for treatment of primary or recurrent VC were identified and reviewed. Conference paper, survey, letter, editorial, book chapter and review were excluded. Time restriction (1990-2018) as concerns the years of the publication was considered. EVIDENCE SYNTHESIS: Primary disease: the median 5-year LC was 43.5% (range 19-68%); the median 5-year DFS was 44.5% (range 44-81%); the median 5-year OS was 50.5% (range 27-85%). Recurrent disease: the median 5-year DFS was 64% (range 56-72%) and the median 5-year OS was 45% (range 33%-57%). Acute ≥ grade 2 toxicity was reported in three patients (1.6%). The severe late toxicity rates (grade 3-4) ranged from 0% to 14.3% (median 7.7%). CONCLUSION: IRT as part of primary treatment for primary and/or recurrent vulvar cancer is associated with promising clinical outcomes.

RESUMO

PURPOSE: The use of MRI for radiotherapy planning purposes is growing but image acquisition using radiotherapy set-ups has impaired image quality. Whether differences in image acquisition set-up could modify organ contouring has not been evaluated. Therefore, we aimed to evaluate differences in contouring between paired of image sets that were acquired in the same scanning session using different parameters. MATERIAL AND METHODS: Ten patients underwent RT treatment planning with MRI co-registration. MRI was carried out using two different set-ups during the same session, MRI radiotherapy set-ups and MRI diagnostic set-ups. Prostates and rectums were retrospectively contoured in both image sets by 5 radiation oncologists and 4 radiologists. Intra-observer analysis was carried out comparing organ volumes, the Dice coefficient and hausdorff distance values between two contouring rounds. Inter-observer analysis was carried out by comparing individual contours to a generated STAPLE consensus contour, which is considered the gold standard reference. RESULTS: No significant differences were observed between MRI acquisition set-ups. Significant differences were observed for the dice and hausdorff parameters, comparing individual contours to the STAPLE consensus contour, when analysing diagnostic images between rounds, although raw values were similar. CONCLUSION: Prostate and rectum contours did not differ significantly when using diagnostic or radiotherapy MRI acquisition set-ups.

RESUMO

INTRODUCTION: The number of patients who have a cardiac implantable electronic device (CIEDs) that undergo a course of radiotherapy is increasing due to the ageing population. The majority of clinical studies only evaluate any CIED malfunction at the end of a course of irradiation or in a case of there being symptoms of possible malfunction. As a result, little data has been collected on CIED status acquired during an active course of irradiation. MATERIAL AND METHODS: We aimed to evaluate the correct functioning of a CIED during a course of radiotherapy. So, a retrospective analysis was made of all patients having CIEDS in a single institution during their course of radiotherapy. All CIEDs were systematically checked before and during the course of radiotherapy according to the risk of device failure and patient dependence. RESULTS: Data was analysed from 56 patients (43 men, 13 women) with a mean age of 78.2 years, of whom 87.5% of the patients carried a pacemaker (PM), the 39% of the patients were PM dependent, and the remaining patients carried an implantable cardioverter-defibrillator (ICD). An observable dose of irradiation was evident in only 10 cases. 69.1% of the CIEDs were checked daily and the remainder were checked weekly. During the radiotherapy course, 82% of the patients did not complain of any cardiological event. The CIED of five patients experienced an increase in the threshold and, in another case, a sudden reduction in the duration of the battery was reported. Another patient with a CIED experienced a cardiac insufficiency episode triggered by a ventricular tachycardia. CONCLUSION: In conclusions, although adverse clinical events from exposure of a CIED to irradiation are rare, they can appear in any group of risk. No dose-dependency was observed on the malfunction of the CIED.

RESUMO

PURPOSE: To determine whether brachytherapy with a single hypofractionated dose of 7 Gy provides the similar vaginal-cuff relapses and safety profile in terms of complications compared to schedules of 2 or 3 fractions of lower doses in patients treated previously with external beam irradiation in postoperative endometrial carcinoma. METHODS/MATERIAL: From June 2003 to December 2016, 325 patients were treated with 3 different schedules of high-dose-rate brachytherapy after external beam irradiation for postoperative endometrial carcinoma. The patients were divided into 3 groups: Group-1: 125 patients were treated with 3 fractions of 4-6 Gy per fraction (3 fractions/week) between 2003 and 2008; Group-2: 93 patients were treated with 2 consecutive daily fractions of 5-6 Gy between 2008 and 2011; Group-3: 107 patients received a single fraction of 7 Gy between 2011 and 2016. Bladder and rectum complications were assessed using RTOG scores and with the objective scores of LENT-SOMA for the vagina. STATISTICS: the chi-square test. RESULTS: The mean follow-up of Groups 1, 2 and 3 was 95, 67 and 51 months, respectively. Three patients in Group-1, 2 in Group-2, 1 in Group-3 developed vaginal-cuff relapse (p = 0.68). No differences were found in late toxicity among the three groups. CONCLUSIONS: One single dose of 7 Gy is safe and effective and may be the best treatment schedule with a similar incidence of vaginal-cuff relapses, complications and patient comfort with less hospital attendance.

RESUMO

PURPOSE: To quantitatively and qualitatively evaluate and compare MR images acquired from the usual diagnostic set-up with images acquired in a radiotherapy set-up. MATERIALS AND METHODS: MR images of a phantom and 18 prostate cancer patients imaging using the usual diagnostic set-up with a curved tabletop (DX-set-up) and using a radiotherapy set-up (RT-set-up) with a flat tabletop, were analysed retrospectively. Quantitative assessments were made by measuring signal-to-noise ratio (SNR) and contrast to noise ratio (CNR). Non-parametric tests were used. Qualitative assessments were made independently by three radiologists. Inter-rater reliability was measured as the percentage of agreement and Gwet's AC2 test. RESULTS: The use of the RT-set-up was linked to 19.3% SNR drop on the phantom image. Up to 24% SNR prostate drop was observed in patients' images. Up to 34% CNR drop was observed in patients' images. Although image quality of the RT-set-up was acceptable, all measured domains were worse than the corresponding DX-set-up. Additionally diagnostic images were linked to a better percentage of agreement among raters. CONCLUSIONS: SNR, CNR and image quality were significantly worse when using the RT-set-up than with the DX-set-up although Image quality in the RT-set-up was acceptable.

RESUMO

OBJECTIVE: To analyze the impact of age on radiotherapy results based on cancer-specific survival (CSS), vaginal-cuff relapses (VCR) and complications analysis in 438 patients with endometrial carcinoma (EC) receiving postoperative radiotherapy (PRT) divided into three age groups for analysis. MATERIALS AND METHODS: From 2003 to 2015, 438 patients with EC were treated with PRT and divided into three age groups: Group-1: 202 patients < 65 years; Group-2: 210 patients ≥ 65 and < 80 years; Group-3: 26 patients ≥ 80 years. Vaginal toxicity was assessed using the objective LENT-SOMA criteria and RTOG scores were recorded for the rectum, bladder, and small bowel. STATISTICS: Chi square and Student's t tests, Kaplan-Meier survival study for analysis of CSS. RESULTS: The mean follow-up was 5.6 years in Group-1, 5.6 years in Group-2 and 6.3 years in Group-3 (p = 0.38). No differences were found among the groups in distribution of stage, grade, myometrial invasion, Type 1 vs. 2 EC and VLSI (p = 0.97, p = 0.52, p = 0.35, p = 0.48, p = 0.76, respectively). There were no differences in rectal, bladder and vagina late toxicity (p = 0.46, p = 0.17, p = 0.75, respectively). A better CSS at 5 years was found in Group-1 (p = 0.006), and significant differences were found in late severe small bowel toxicity in Group-3 (p = 0.005). VCR was increased in Group-3 (p = 0.017). CONCLUSIONS: Patients ≥ 65 years had a worse outcome in comparison to younger patients. Late vaginal, rectal and bladder toxicities were similar in the three groups, although an increase of severe late small bowel toxicity led to IMRT in patients ≥ 80 years. Further larger studies are needed including quality of life analysis in patients ≥ 80 years.

RESUMO

Clinical indications of brachytherapy in non-melanoma skin cancers, description of applicators and dosimetry recommendations are described based on the literature review, clinical practice and experience of Spanish Group of Brachytherapy and Spanish Society of Medical Physics reported in the XIV Annual Consensus Meeting on Non Melanoma Skin Cancer Brachytherapy held in Benidorm, Alicante (Spain) on October 21st, 2016. All the recommendations for which consensus was achieved are highlighted in blue. Regular and small surfaces may be treated with Leipzig, Valencia, flap applicators or electronic brachytherapy (EBT). For irregular surfaces, customized molds or interstitial implants should be employed. The dose is prescribed at a maximum depth of 3-4 mm of the clinical target volume/planning target volume (CTV/PTV) in all cases except in flaps or molds in which 5 mm is appropriate. Interstitial brachytherapy should be used for CTV/PTV >5 mm. Different total doses and fraction sizes are used with very similar clinical and toxicity results. Hypofractionation is very useful twice or 3 times a week, being comfortable for patients and practical for Radiotherapy Departments. In interstitial brachytherapy 2 fractions twice a day are applied.

RESUMO

PURPOSE: To analyze the vaginal-cuff local control (VCC) and toxicity in postoperative endometrial carcinoma patients (EC) underwent high-dose-rate brachytherapy (HDR-BT) administered daily. MATERIALS AND METHODS: 154 consecutive patients received postoperative HDR-BT for EC from January 2007 to September 2011. FIGO-staging I-IIIC2 patients were divided into two groups according to risk classification: Group 1 (94/154) included high-risk or advanced disease patients and Group 2 (60/154) included intermediate-risk EC patients. Group 1 underwent external beam irradiation (EBI) plus HDR-BT (2 fractions of 5 Gy) and Group 2 underwent HDR-BT alone (4 fractions of 5 Gy). Toxicity evaluation was done with RTOG scores for bladder and rectum, and the objective criteria of LENT-SOMA for vagina. RESULTS: With a median follow-up of 46.7 months (36.6-61 months) only two patients developed vaginal-cuff recurrence in Group 1 (2.1 %) and none in group 2 (0 %). Early toxicity in Group 1 appeared 5.3 % in rectum, 7.5 % in bladder (G1-G2) and 2.1 % in vagina (G1); late toxicity was present in 7.3 % in rectum (all G1-G2 but 1 G3) and in 27.7 % in vagina (all G1-G2 but one G4). In Group 2, 6.7 % developed acute G1-G2 bladder and 6.6 % acute vaginal (G1-G2) toxicity. No late rectal or bladder toxicity was observed; 21.7 % of G1-G2 presented late problems in vagina. CONCLUSIONS: The present HDR-BT schedule of 2 fractions of 5 Gy after EBI and 4 fractions of 5 Gy administered daily showed excellent results in terms of VCC and toxicity.

RESUMO

BACKGROUND: High-dose-rate brachytherapy (HDR-BT) is an accepted part of treatment for endometrial carcinoma and is usually performed in 1-2 fractions per week using different total doses and doses per fraction. To reduce the overall treatment time, HDR-BT was administered with a 3-4 days/week schedule. PATIENTS AND METHODS: From June 2003 to December 2008, 164 patients with stage I-IIIc endometrial carcinoma were treated with HDR-BT (4-5 Gy per fraction). The patients were divided into two groups; Group 1 (40/164 patients) was treated with HDR-BT alone (6 fractions; 4 fractions/week) and Group 2 (124/164 patients) was treated with both (External Beam Radiotherapy [EBRT] + HDR-BT: 3 fractions/week). Complications were analyzed using RTOG scores for rectum and bladder and the objective scores of LENT-SOMA for vaginal complications. RESULTS: The mean followup was 48 months. In Group 1, 35 % of patients underwent treatment in ≤10 days and 65 % in >10 days. In Group 2, 53.2 % received treatment in ≤5 days and in 46.8 % in >5 days. Vaginal relapse was observed in only two patients (1.2 %), both having received adjuvant EBRT + HDR-BT. Acute vaginal toxicity appeared in 8.5 % and late vaginal toxicity in 20.7 % of patients with 13.4 % being G1, 6.7 % G2 and only 0.6 % being G4. No statistically significant differences were found in complications in either brachytherapy group regardless of the overall time. CONCLUSION: In our series, three fractions given in 3-5/days after EBRT or six fractions in 10 days, is a safe regimen in terms of complications and local control.

RESUMO

Low-dose radiotherapy (LD-RT) has been used for several benign diseases, including arthrodegenerative and inflammatory pathologies. Despite its effectiveness in clinical practice, little is known about the mechanisms through which LD-RT modulates the various phases of the inflammatory response and about the optimal dose fractionation. The objective of this review is to deepen knowledge about the most effective LD-RT treatment schedule and radiobiological mechanisms underlying the anti-inflammatory effects of LD-RT in various in vitro experiments, in vivo studies, and clinical studies.

RESUMO

Radiotherapy (RT) is commonly used as adjuvant treatment following hysterectomy and double oophorectomy in endometrial carcinoma. Prophylactic vaginal brachytherapy (BT) is the most common treatment in BT units. The PORTEC and GOG 99 studies have attempted to clarify the indications of BT and postoperative external RT, changing treatment standards. However, prophylactic BT regimens are very varied and there is currently no consensus on how to treat patients in terms of dose per fraction and number of fractions. Moreover, unoperated cases of endometrium are uncommon and there is limited experience in their treatment with BT. The 9th Consensus Meeting of the SEOR and SEFM Brachytherapy Group, held in Malaga on 11 March 2011, was therefore dedicated to "Brachytherapy in Endometrial Carcinoma". This article presents the consensus on treatment of endometrial carcinoma in operated (prophylactic vaginal BT) and unoperated (endouterine BT) patients.

RESUMO

Neuroendocrine small cell carcinoma is a malignant neoplasm that most frequently arises in the lung. Salivary gland involvement is rare, and the parotid is the main gland affected. We describe the fine-needle aspiration (FNA) cytology findings, the immunophenotypical study and the differential diagnosis of a small cell carcinoma that presented in the parotid of a 91-year-old man. The tumour was treated only with radiotherapy and presented a complete response, with no evidence of the disease after three years of follow-up. This is the first case reported in the literature with good outcome after exclusive irradiation.

RESUMO

Tamoxifen (TMX) has been related with the development of uterine sarcomas. Since the first reported case in 1988, 65 TMX-related cases have been referred to. Here we present three new cases of uterine sarcomas in patients with breast cancer treated with TMX and we comment on the outcome of the cases described in the literature. In the past 25 years, 60 uterine sarcomas have been diagnosed and treated in Hospital Clínic. Three patients have previously received TMX 20 mg/day for 3, 5, and 7 years for breast cancer. Uterine sarcoma appeared 5, 5, and 7 years, respectively, after the start of TMX treatment, and all of them had stage I (FIGO) disease. Two patients had a carcinosarcoma and one patient had an adenosarcoma. After treatment, the disease progressed in two patients and the third patient is alive having a follow-up of 42 months. The low incidence of uterine sarcomas makes it difficult to establish a relationship with TMX. Nevertheless, looking at the literature data, 20 mg/day of TMX over 1 year could be enough to develop uterine sarcoma; the sarcoma appears mainly during the first 8 years and seem to behave more aggressively. Although only 65 cases have been reported in the past 14 years, a strict follow-up is necessary in patients with breast cancer receiving TMX therapy.

RESUMO

Patients with head and neck cancers can develop salivary hypofunction after radiotherapy. The use of pilocarpine during radiotherapy treatment has been shown to be an effective treatment, although its usefulness is being discussed. The aim of this study was: (1) to determine the value of a semiquantitative scintigraphy method for measuring the uptake and excretory salivary function of patients with head and neck irradiated tumours; and (2) to study the usefulness of pilocarpine as a salivary gland protector during radiotherapy. We prospectively studied 49 patients (mean age 61 years, range 29-87 years) with head and neck cancer in need of radiotherapy. Patients were divided into two groups consecutively: group P (26 patients) received 5 mg of pilocarpine three times per day starting the day before radiation therapy, and group NP (23 patients) received radiotherapy without pilocarpine and were used as the control group. Salivary gland scintigraphy and a visual analogue scale (VAS) of mouth dryness were obtained from each patient before radiotherapy and during the first year after treatment. The most frequent finding after radiotherapy was a quick impairment in parotid and submaxillary excretion (P < 0.001). There were no statistical differences comparing the pilocarpine group against the non-pilocarpine group. Parotid and submaxillary uptake significantly decreased after radiotherapy in both groups (P < 0.001). However, a tendency to recover within the pilocarpine group was observed in both the parotids and the submaxillary glands at 12 months. No differences were found comparing the VAS results in both groups. Strikingly, VAS data did not correlate with salivary gland dysfunction observed by means of scintigraphy. In conclusion, salivary scintigraphy is a useful technique to evaluate objectively the salivary gland function of patients with head and neck irradiated tumours as well as to test the response to pilocarpine. However, despite better results on the salivary uptake at 12 months, pilocarpine did not significantly improve salivary gland function.

RESUMO

PURPOSE: The study of acoustic voice parameters (fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio) in extended vowel production, oral reading of a standard paragraph, spontaneous speech and a song in irradiated patients for Tis-T1 vocal cord carcinoma. METHODS AND MATERIALS: Eighteen male patients irradiated for Tis-T1 vocal cord carcinoma and a control group of 31 nonirradiated subjects of the same age were included in a study of acoustic voice analysis. The control group had been rigorously selected for voice quality and the irradiated group had previous history of smoking in two-thirds of the cases and a vocal cord biopsy. Radiotherapy patients were treated with a 6MV Linac receiving a total dose of 66 Gy, 2 Gy/day, with median treatment areas of 28 cm(2). Acoustic voice analysis was performed 1 year after radiotherapy, the voice of patients in extended vowel production, oral reading of a standard paragraph, spontaneous speech, and in a song was tape registered and analyzed by a Kay Elemetric's Computerized Speech Lab (model CSL# 4300). Fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio were obtained in each case. Mann Whitney analysis was used for statistical tests. RESULTS: The irradiated group presented higher values of fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio. Mann-Whitney analysis showed significant differences for fundamental frequency and jitter in vowel production, oral reading, spontaneous speech, and song. Shimmer only showed differences in vowel production and harmonics-to-noise ratio in oral reading and song. CONCLUSIONS: In our study only fundamental frequency and jitter showed significant increased values to the control group in all the acoustic situations. Sustained vowel production showed the worst values of the acoustic parameters in comparison with the other acoustic situations. This study seems to suggest that more work should be done in this field.

RESUMO

PURPOSE: In order to provide more information for the clinician and to analyze the impact of radiation therapy on the loco-regional disease-free interval (LRFI), disease-free interval (DFI) and specific overall survival (OS), a multicentric retrospective study of uterine sarcomas has been undertaken using cases reported to the Grup Oncològic Català-Occità (GOCO). PATIENTS AND METHODS: One hundred three patients were selected for this study with a median follow-up period of 49 months. Patients were restaged using the FIGO classification for endometrial adenocarcinoma. Radiotherapy was administered postoperatively to the entire pelvis in 52% of cases (54/103) and was combined with brachytherapy in 24 patients. Mean given dose was 48 Gy, with a 95% confidence interval of 45 to 50 Gy. Variables have been tested for homogeneity between hospitals. Univariate and multivariate analyses have also been carried out. RESULTS: Mean age of the selected patients was 59 years (range 35-84). Stages were distributed as follows: 66 patients (64%) in Stage I; 16 in Stage II (15.5%); 12 in Stage III (11.5%); 9 patients in Stage IVa (9%). Pathological distribution was 41.5% leiomyosarcoma, 39% mixed Mullerian tumours, 16.5% stromal sarcomas, and 2.9% of a miscellaneous group. Overall survival for the entire group was 63.7% and 56% at 2 and 5 years, respectively. Probability of LRFI reached 59.8% at 2 years and 57.4 at 5 years. The DFI at 2 and 5 years were 52.9 % and 48.7%, respectively. The LRFI probability was 41% and 36% at 2 and 5 years, respectively, without radiotherapy and reached 76% at 2 and 5 years among those patients treated with radiotherapy. There was also an increase in DFI probability because of the effect of radiotherapy, from 35% to 68.5% and from 33% to 53% at 2 and 5 years, respectively. The overall survival probability for patients treated with radiotherapy was 76% and 73% at 2 and 5 years, respectively and 51% at 2 years and 37% at 5 years without radiotherapy. Multivariate analysis demonstrated that radiotherapy improved LRFI, DFI, and overall survival. CONCLUSION: We conclude that postoperative radiotherapy in our series of patients diagnosed with uterine sarcoma has an impact on loco-regional and disease-free progression intervals and survival.
