Introduction Radiotherapy is used to treat breast cancer. The administration of treatment with DIBH makes it
possible to remove the organs at risk from the area to be treated. Thus, it is possible to reduce future complications. The lack of respiratory training, anxiety and patient stress are some factors that can compromise the correct execution of apnea, making the treatment more time consuming. The aim of this work is to study the applicability of the DIBH technique in patients undergoing radiation therapy and to create a respiratory training protocol. Methodology A bibliographic search was carried out with consultation of databases and digital libraries. A questionnaire was applied to 34 radiotherapy technicians with functions in the treatment unit and CT planning. The questionnaire was released by professional associations and radiotherapy services. Results / Discussion: According to the interviewees and the consulted bibliography, DIBH is mainly applied in the treatment of left breast tumors. It is associated with an increase in treatment time and patient anxiety. According to respondents, anxiety and difficulties initially presented by patients, when performing DIBH, tend to disappear during treatment sessions. Final considerations The breathing training session allows the patient
to become familiar with the breathing technique. During the training session, the patient should be provided with feedback on his breathing in order to proportionate the improvement of the DIBH. The training should be carried out at home, before the planning CT, as many times as possible.
Objetivo
Este trabalho apresenta uma revisão bibliográfica
sobre a determinação da importância do
replaneamento em doentes com cancro da mama
submetidos a radioterapia com a técnica de IMRT.
Metodologia
Foi realizada uma ampla pesquisa em plataformas
científicas como a Pubmed, Researchgate,
ScienceDirect e diversos jornais científicos: The
Breast, Radiotherapy and Oncology, The International
Journal of Radiation Oncology e Medical Dosimetry
num espaço temporal desde novembro de 2004
a março de 2018. A informação recolhida foi
considerada se estudasse as alterações volumétricas
do volume do boost (BTV) entre a Tomografia
Computorizada (TC) de planeamento inicial e a TC de
replaneamento.
Resultados
O volume do boost apresenta alterações entre as
fases do tratamento de radioterapia com a técnica
de IMRT, com especial ênfase em doentes que
apresentam edema ou grandes volumes mamários
durante o tratamento de radioterapia. Verificou-se
também que, as alterações do BTV poderão implicar
um acréscimo de dose na mama ipsilateral.
Conclusões
É aconselhado um replaneamento entre a primeira
e a segunda fase de tratamento em doentes com
cancro de mama submetidos a radioterapia com
IMRT.
