Magnetic resonance imaging for planning intracavitary brachytherapy for the treatment of locally advanced cervical cancer.

Cervical cancer is the third most common gynecological cancer. Its treatment depends on tumor staging at the time of diagnosis, and a combination of chemotherapy and radiotherapy is the treatment of choice in locally advanced cervical cancers. The combined use of external beam radiotherapy and brachytherapy increases survival in these patients. Brachytherapy enables a larger dose of radiation to be delivered to the tumor with less toxicity for neighboring tissues with less toxicity for neighboring tissues compared to the use of external beam radiotherapy alone. For years, brachytherapy was planned exclusively using computed tomography (CT). The recent incorporation of magnetic resonance imaging (MRI) provides essential information about the tumor and neighboring structures making possible to better define the target volumes. Nevertheless, MRI has limitations, some of which can be compensated for by fusing CT and MRI. Fusing the images from the two techniques ensures optimal planning by combining the advantages of each technique.

[Accelerated partial breast irradiation with multicatheters during breast conserving surgery for cancer]. / Irradiación parcial acelerada con multicatéteres en la cirugía conservadora por cáncer de mama.

INTRODUCTION: Accelerated partial breast irradiation (APBI) with multicatheters after lumpectomy for breast cancer (BC) may be an alternative to whole breast irradiation in selected patients. The aim is to show our 5 year experience. METHOD: Between June 2007 and June 2012, 87 BC patients have been evaluated for APBI. Inclusion criteria were: age over 40 years, unifocal tumour, infiltrating ductal or intraductal carcinoma, tumour size smaller than 3 cm and no lymph node involvement. Complications, cosmetic results and local and distant recurrences were evaluated. RESULTS: Treatment was completed in 48 patients and contraindicated in 39. The average age of treated patients was 59 years. Operating time was 123 min with 9 implanted catheters in each patient. No complications were observed during surgery or radiotherapy. Patients were discharged from hospital after 4 days. Tumour size was 11 mm. Of these, 35 were infiltrating ductal and 13 intraductal carcinomas. A total of 44 patients received adjuvant treatment. Mean follow-up was 22 months with no evidence of local or distant recurrence. The cosmetic outcome was good or excellent in 66% of cases. CONCLUSIONS: APBI with multicatheter placed after lumpectomy for BC is feasible and safe but requires a strict selection of patients.

Prior MRI-imaging impact of patients submitted to brachytherapy for prostate cancer.

INTRODUCTION: Brachytherapy for the treatment of prostate cancer is a well-established option. Use of Multiparametric Magnetic Resonance Imaging (mpMRI) for staging and diagnosis of prostate cancer has come to change the current paradigm. In this study we aim to assess the impact of performing mpMRI to evaluate the presence of extracapsular lesions before brachytherapy in patients with prostate cancer concerning biochemical recurrence and time to nadir. METHODS: Review data from 73 patients submitted to brachytherapy. The following factors were evaluated: age, initial PSA, MRI local staging results, ISUP, nadir, time to nadir, PSA at one-year, biochemical recurrence, and time to recurrence. RESULTS: Median age was 68 years (51-72) and median follow-up 53 months (30-72). Concerning imaging modality 30,1% (n = 22) patients performed mpMRI. In the mpMRI group, 90.9% (n = 20) had at least one suspect lesion on mpMRI. Time to nadir was 27 months (3-64) in patients where mpMRI was not performed and 23.5 months (2-48) in patients submitted to mpMRI (P = .244). The median value of nadir was 0.42 ng/mL (<0.001-2) in patients submitted to mpMRI and vs 0.28 ng/mL (<0.001-4) in patients without MRI (P = .062) Recurrence utilizing Phoenix criteria was 9% (n = 2) in patients with MRI and 9.2% (n = 5) without mpMRI (P = .456), median follow-up of 43 months (12-72) for the MRI group with 58 months (30-78) for the non-mpMRI group. Both groups were statistically similar. CONCLUSION: Our results allow us to conclude that in our series MRI did not influence biochemical recurrence, time to nadir, or nadir value.

Usefulness of 18F-Choline Positron Emission Tomography - Computed Tomography in the therapeutic management of patients with biochemical recurrence of prostate adenocarcinoma treated with brachytherapy. / Utilidad de la tomografía de emisión de positrones / tomografía computarizada con 18F-colina en el manejo terapéutico de pacientes con recidiva bioquímica de adenocarcinoma de próstata tratados con braquiterapia.

OBJECTIVE: The objective of the study was to evaluate the usefulness of 18F-choline PET/CT in biochemically recurrent prostate cancer patients treated with brachytherapy, as well as to assess the changes in therapeutic management derived from its outcome. MATERIAL AND METHODS: Retrospective study of 20 patients between 51 and 78 years old, with a history of prostate adenocarcinoma that had been treated with brachytherapy and presented biochemical recurrence (PSA 3.1-12 ng/ml) and staging tests (CT and bone scan) without alterations, were included. The findings visualized in the PET/CT scan with 18F-choline were correlated with the histopathology and/or the evolution of the PSA after therapy. RESULTS: 18F-choline PET/CT scan only detected local recurrence in 15 patients. Local and regional recurrences were seen in 4 patients, and 1 patient presented local and bone recurrence. Local recurrence detected in PET was confirmed by anatomopathological studies in 85% of the cases. In one patient, these findings (PET scan) turned out to be prostatitis, and it could not be confirmed in another patient. Of the cases with local and regional recurrence, local recurrence was histologically confirmed in 3 out of 4 patients. 18F-choline PET/CT changed the therapeutic management in 25% of the patients, discarding the initially planned salvage surgery in 3 cases, 1 radiotherapy and 1 brachytherapy. CONCLUSION: 18F-choline PET/CT could be a useful technique in the group of patients with biochemical recurrence after brachytherapy, providing locoregional and distant involvement findings which had not been detected with conventional imaging tests, thus determining a more adequate therapeutic management.

Evaluación de los puntos "A" como parámetro dosimétrico en braquiterapia ginecológica guiados por imágenes tridimensionales

Objetivos: se evaluó si la técnica de prescripción de dosis puntual, punto "A", es adecuada para la estimación de dosis en el volumen de tratamiento clínico por alta tasa de dosis (CTV-HR), usando la braquiterapia ginecológica 3D. Métodos: se recopiló planes de tratamiento para 35 pacientes con cáncer cervicouterino estadio IB2-IVA (140 fracciones o planes de tratamiento) tratados entre los años 2019 al 2021, cuya dosis prescrita fue de 28 Gy en 4 fracciones. Se reconstruyeron los puntos "A", se normalizó la dosis prescrita a la isodosis del 100% para comparar con las dosis en CTV-HR (D90%). Resultados: el promedio de la dosis absorbida al CTV- HR (D90%) fue de 88,82 ± 2,53 Gy y al normalizar la isodosis del 100% al punto "A", se obtuvo dosis promedio en CTV-HR (D90%) de 99,3±5,85Gy. Esta variación de dosis promedio al CTV-HR (D90%) representó un incremento del 18%, dando como resultado que un 80% de los tratamientos correspondiente a 28 pacientes queden fuera de la variación aceptable del protocolo EMBRACE II y solo un 20% de los tratamientos correspondientes a 7 pacientes se encuentren dentro del rango de la variación aceptable del protocolo en mención. Conclusiones: la técnica de prescripción de dosis al punto "A", se traduce clínicamente en una sobredosis del tejido tumoral y sano (recto, sigmoide, vejiga e intestino).

Objective: to assess whether the punctual dose prescription technique, point A, is adequate for dose estimation in CTV-HR using 3D gynecological brachytherapy. Methods: treatment plans were collected for 35 patients with stage IB2-IVA (140 fractions or treatment plans) cervical cancer treated between 2019 and 2021, whose prescribed dose was 28Gy in 4 fractions. Points A were reconstructed, the prescribed dose was normalized to 100% isodose to compare with the doses in CTV- HR(D90%). Results: the average dose absorbed at CTV-HR(D90%) was 88.82 ±2.53 Gy and when normalizing the isodose of 100% at point A, average dose at CTV-HR(D90%) was obtained. of 99.3±5.85Gy. This average dose variation to the CTV-HR(D90%) represented an increase of 18%, resulting in 80% of the treatments corresponding to 28 patients falling outside the acceptable variation of the EMBRACE II protocol and only 20% of the treatments corresponding to 7 patients are within the range of the acceptable variation of the protocol in question. Conclusions: the dose prescription technique at point A clinically translates into an overdose of tumor and healthy tissue (rectum, sigmoid, bladder and intestine).

High-dose rate brachytherapy as monotherapy in prostate cancer: A systematic review of its safety and efficacy. / Braquiterapia de alta tasa de dosis como monoterapia en cáncer de próstata: una revisión sistemática sobre eficacia y seguridad.

CONTEXT: High-dose rate brachytherapy (HDR-BT) is an increasingly popular treatment for patients with localised prostate cancer (PC). OBJECTIVE: To assess the safety and efficacy of HDR-BT as monotherapy in PC. ACQUISITION OF EVIDENCE: A systematic literature review was conducted through searches on MEDLINE (PubMed), Cochrane Library, CDR, ClinicalTrials and EuroScan. We assessed safety and efficacy indicators. SUMMARY OF THE EVIDENCE: We selected 2 reviews and 12 uncontrolled studies, included in these 2 reviews. In terms of efficacy, local control in 6 studies was 97-100%. The biochemical progression-free survival varied as follows: 85-100% for low risk and 79-92% for high risk. Survival free of metastases was >95% at 8 years, except in one study where the survival rate was 87% at 5 years. The overall survival was ≥95% in 8 studies. In terms of safety, most of the studies recorded acute and long-term genitourinary and gastrointestinal complications, especially grade ≥2. Only 3 studies found grade 4 complications. All studies, except for one without complications, observed genitourinary complications that were more frequent and severe than the gastrointestinal complications. Two studies assessed the quality of life and showed an initial reduction in various domains and subsequent partial or total recovery, except in the sexual domain. CONCLUSIONS: HDR-BT is effective as monotherapy, especially in cases of low to intermediate risk. There is insufficient information on high-risk patients. The short to medium-term toxicity was acceptable. Further research needs to be funded to provide more information on the long-term safety and efficacy of this treatment.

Criterio de inclusión: diagnóstico, tratamiento y seguimiento en nuestro centro. Criterio de exclusión: historia incompleta y diagnóstico o tratamiento en otro centro. Variables de estudio: tipo de tumor y de tratamiento. Se realizó un análisis descriptivo. Las posibles asociaciones se comprobaron mediante χ2, Fisher, t de Student y prueba de Mann-Whitney. RESULTADOS: Se estudiaron 149 pacientes, con edad media al diagnóstico de 69.38 años ± 9.6 años. El 86.6% (n = 129) de las pacientes estaban en la posmenopausia. El 68% (n = 101) eran obesas y el 54.7% (n = 81) hipertensas. El 54.7% (n = 81) se diagnosticaron en estadio IA. El 68.4% de los tumores grado 3 tuvieron infiltración miometrial mayor al 50%, el 28.6% grado 1 (p < 0.001). De las pacientes que recibieron radioterapia o braquiterapia el 46% estaba en estadios avanzados; 76% en estadio IB, 26% en estadio IA (p < 0.001). El 91.3% de los tumores estadio I fueron tipo I, en los estadios avanzados hubo 48.6% de tumores tipo I (p < 0.001). El 87.4% de los tumores grados 1 o 2 se encontraron en estadio I, un 45.2% de los tumores grado 3 en estadio I (p < 0.001). CONCLUSIONES: La mayoría de las pacientes tenía más de 60 años y eran diabéticas, hipertensas y obesas. El cáncer de endometrio suele diagnosticarse en estadios tempranos. La braquiterapia es la coadyuvancia más indicada.

Abstract OBJECTIVE: To retrospectively describe the behavior of endometrial cancer in patients diagnosed at the Complexo Hospitalario Universitario de Ourense. MATERIALS AND METHODS: Descriptive, observational and retrospective study in the Complexo Hospitalario Universitario de Ourense between September 2014 and January 2018. Inclusion criteria: diagnosis, treatment and follow-up in our center. Exclusion criteria: incomplete history and diagnosis or management in another center. Patient, tumor and treatment variables were collected. A descriptive analysis was performed. Possible associations were tested by Chi-square, Fisher, Student's t-test and Mann-Whitney test. RESULTS: 149 patients were studied, with mean age at diagnosis of 69.38 years ± 9.6 years. 86.6% (n = 129) of the patients were postmenopausal. 68% (n = 101) were obese and 54.7% (n = 81) hypertensive. 54.7% (n = 81) were diagnosed at stage IA. 68.4% of grade 3 tumors had myometrial infiltration greater than 50%, 28.6% grade 1 (p < 0.001). Of the patients who received radiotherapy or brachytherapy 46% were advanced stage; 76% stage IB, 26% stage IA (p < 0.001). 91.3% of stage I tumors were type I, in advanced stages there were 48.6% of type I tumors (p < 0.001). 87.4% of grade 1 or 2 tumors were stage I, 45.2% of grade 3 tumors were stage I (p < 0.001). CONCLUSIONS: Most patients were older than 60 years and were diabetic, hypertensive and obese. Endometrial cancer is usually diagnosed at early stages. Brachytherapy is the most indicated adjuvant.

Principais implicações terapêuticas à qualidade de vida de pacientes com câncer de colo uterino: uma revisão narrativa / Therapeutic implications to the quality of life of cervical cancer's patients: a narrative review

O câncer de colo uterino é o quarto tipo mais incidente e fatal entre as mulheres no Brasil e no mundo, o que representa mundialmente em torno de 600 mil novos casos e mais de 300 mil mortes a cada ano. Assim como o diagnóstico, o tratamento da doença pode impactar de forma significativa a qualidade de vida dessas pacientes. A aplicação de questionários que avaliem os diferentes aspectos da qualidade de vida das mulheres afetadas por esse câncer é uma ferramenta relevante, pois auxilia na compreensão e identificação dos principais danos relacionados ao tratamento. Este trabalho visa analisar a literatura atual que investiga e relata os principais efeitos à qualidade de vida de mulheres com câncer de colo uterino associados a diferentes modalidades terapêuticas e, desse modo, contribuir nas escolhas de tratamento e manejo clínico que resultem em menores impactos à qualidade de vida dessas mulheres.(AU)

Cervical cancer is the fourth most incident and fatal cancer type among women in Brazil and worldwide. This data represents around 600 thousand new cases worldwide each year and more than 300 thousand lives lost. Both diagnosis and treatment can significantly impact the quality of life of cervical cancer patients. The application of questionnaires that assess the different aspects of the quality of life of women affected by this cancer is a relevant tool, as it helps to understand and identify the main damages related to the treatment. This article aims to analyze the current literature that reports the main effects on the quality of life of women with cervical cancer associated with different therapeutic modalities. In this way, the review could assist in the treatment choices that imply less impact on the quality of life of these women.(AU)

Radioterapia en cáncer de la región maxilofacial / Radiation therapy in cancer of the maxillofacial region

RESUMEN Introducción: La Radiobiología es la ciencia perteneciente a la biología que estudia los efectos de los distintos tipos de radiación sobre la materia viva. Objetivo: Identificar la evidencia científica respecto a la radioterapia del paciente con cáncer en la región maxilofacial. Métodos : Se realizó una revisión de la de literatura acerca del tema en motores de búsqueda como: las bases de datos electrónicas PubMed, Medline, Cochrane, Hinari y SciELO. Para la búsqueda de la información se utilizaron las palabras clave: cáncer de cabeza y cuello, tratamiento del cáncer de la región maxilofacial, radioterapia, braquiterapia y tipos de radioterapia. Resultados: Para el tratamiento se necesita evaluar las características del tumor y determinar el estadio tumoral, la localización y extensión de la enfermedad, así como los hallazgos patológicos que dictan la conducta adecuada como la cirugía, radioterapia, quimioterapia, terapia hormonal, inmunoterapia y terapia dirigida. La dosis máxima tolerada en relación con los órganos críticos oscila entre 50 y 76 Gy. Con la braquiterapia se puede colocar la fuente radiactiva dentro del paciente en cavidades anatómicas cerca del tumor o en el lecho tumoral. Esto permite administrar dosis elevadas de irradiación muy eficaces, al tumor o zona de riesgo. Los efectos adversos de las radiaciones ionizantes según la célula afectada pueden ser daño genético y somático. Conclusiones: En el tratamiento del cáncer la radioterapia es una opción primordial, siempre con el precepto que ofrezca buenos resultados en cuanto a eficacia, tolerabilidad y calidad de vida, al causar el menor daño posible a los enfermos y con las nuevas tecnologías puede incrementar el éxito y garantizar que el procedimiento continúe con calidad.

Introduction: Radiobiology is the science belonging to the biology that studies the effects of the different types of radiation on the lively matter. Objective: Identifying the scientific evidence in relation to radiation therapy of the patient with cancer of the maxillofacial region. Methods: A literature revision was carried out in search engines as: The electronic data bases PubMed, Medline, Cochrane, Hinari, and SciELO. For the search for information the key words used were head and neck cancer, treatment of the cancer of the maxillofacial region, radiation therapy, brachytherapy and types of radiation therapy. Results: For the treatment it is needed to evaluate the characteristics of the tumor and to determine the tumor stage, the location and extension of disease, as well as the pathological findings that dictate the conduct made suitable like the surgery, radiation therapy, chemotherapy, hormonal therapy, immunotherapy and directive therapy. The maximum dose tolerated relating to the critical organs oscillates between 50 and 76 Gy. With the brachytherapy the radioactive source inside the patient can place itself in reservoirs, close to the tumor or in the tumor area. This allows managing dose lifted of irradiation very effective, to the tumor or zone of risk. The adverse effects of the ionizing radiations according to the impaired cell can be genetic and somatic damage. Conclusions: In the treatment of cancer, radiation therapy is a primary option, always with the precept that offers good results as to efficacy, tolerance and quality of life, causing the smaller possible damage to the sick and with the new technologies it can increase success and guarantee that a procedure keeps on being high-quality.

High dose rate brachytherapy in early stage squamous-cell carcinoma of the lip. / Braquiterapia de alta tasa en el carcinoma escamoso de labio en estadios iniciales.

INTRODUCTION AND GOALS: To analyze the results obtained after treatment of early stage (T1-T2) squamous cell carcinoma of the lip with high dose rate brachytherapy and evaluate the efficacy of this treatment in both local and regional control. MATERIALS AND METHODS: Retrospective analysis of the treatments performed at our department from March 1999 to March 2013 with high dose rate brachytherapy with rigid needles. We included 68 patients, 63 men and 5 women; 37 patients (54.4%) presented a T1 tumour, less than or equal to 2cm, while the other 31 (45.6%) were classified as T2. Median total dose was 45Gy, with a median dose per fraction of 5Gy x 9 fractions twice a day for 5 days. RESULTS: With a mean follow-up of 56.4 months, local control was 96.9%. Stratifying by tumour size, local control of T1 cases was 100%, while T2 achieved 93.2% (2 local recurrences). Regional control at 5 years was 93.8% for T1, and 80.8% for T2. In 11 cases with elective cervical treatment, no regional failure happened. As for toxicity, no patient presented soft tissue, or bone, necrosis. All patients achieved good or excellent cosmetic and functional results. CONCLUSIONS: High dose rate brachytherapy allows effective, safe treatments for squamous cell carcinoma of the lip, with good aesthetic and functional results. It can be considered a valid alternative for surgery in early stage tumours.
