Conformal radiotherapy for hepatocellular carcinoma

Critical Reviews in Oncology/Hematology, 2008
Technical advancements in radiation therapy (RT) have facilitated the safe delivery of conformal, dose-escalated radiation to a wide spectrum of hepatocellular carcinoma (HCC) patients. A variety of doses and RT fractionation schemes have been used, and RT has been used in combination with transarterial chemoembolization (TACE).

Target dose conformity in 3-dimensional conformal radiotherapy and intensity modulated radiotherapy

Radiotherapy and Oncology, 2004
Dose conformity to the planning target volume is an important criterion in radiotherapy treatment planning, for which the conformity index is a useful assessment tool. The purpose of this study is to compare the differences in CI for the treatment planning of four cancers including the nasopharynx, oesophagus, lung and prostate.Seventy patients with ...

Conformal Radiotherapy and Intensity-modulated Radiotherapy: Clinical Data

Acta Oncologica, 2000
Conformal radiotherapy (CRT) is based on three hypotheses: (i) a higher rate of local control can improve the survival rate; (ii) dose escalation can increase tumor control; and (iii) CRT allows the delivery of higher doses by decreasing the incidence of late effects. These postulates are now supported by several data.

[Conformal radiotherapy].

Casopis lekaru ceskych, 2003
The aim of curative radiotherapy is the administration of tumor-lethal dose to an exactly defined target volume with minimal surrounding healthy tissue toxicity. In the conformal radiotherapy it is possible to conform the shape of irradiated volume to an irregular target volume.

CONFORMAL RADIOTHERAPY FOR BRAIN TUMOURS

Hematology/Oncology Clinics of North America, 2001
The technical improvements of three-dimensional conformal radiotherapy can decrease the toxicity of brain treatment to acceptable levels. The adoption of the technique by more centers would allow for the potential advantages of three-dimensional radiotherapy to be employed in a greater number of patients.

[Conformal radiotherapy].

Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie, 1999
Conformal radiotherapy is a new irradiation technique made possible by technological improvements, especially progress in imaging and 3D dosimetry. By conforming the volume irradiated as closely as possible to the clinical anatomical target volume, conformal radiotherapy is designed to deliver a higher dose to the tumour volume, while more effectively ...

[Conformal radiotherapy: tomotherapy].

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2001
Conformal radiation therapy allows the possibility of delivering high doses at the tumor volume whilst limiting the dose to the surrounding tissues and diminishing the secondary effects. With the example of the conformal radiation therapy used at the AZ VUB (3DCRT and tomotherapy), two treatment plans of a left ethmoid carcinoma will be evaluated and ...

Image guidance for precise conformal radiotherapy

International Journal of Radiation Oncology*Biology*Physics, 2003
To review the state of the art in image-guided precision conformal radiotherapy and to describe how helical tomotherapy compares with the image-guided practices being developed for conventional radiotherapy.Image guidance is beginning to be the fundamental basis for radiotherapy planning, delivery, and verification.

Stereotactically guided conformal radiotherapy for meningiomas

Radiotherapy and Oncology, 1999
Stereotactically guided conformal radiotherapy, (SCRT) is a high precision technique of conformal radiotherapy (RT) which reduces the volume of normal tissue irradiated compared to conventional RT and may lead to a reduction in long-term toxicity We describe the technique and the preliminary results in patients with inoperable, residual or recurrent ...
