Background: In the current study the effect of shielded colpostat on rectum received dose was calculated in cervical brachytherapy using Monte Carlo (MC) method. Materials and Methods: Two 60Co sources of GZP6 brachytherapy unit used for intracavitary treatments were simulated using MCNPX Monte Carlo code. Also the two types of colpostats including shielded and unshielded were simulated inside ...

Background. Combined radiation therapy is the «gold standard» for treatment of stages IIB-IVA cervical cancer (cervical cancer). Given data statistical indicators cancer, study new approaches to and implementation in clinical practice modern technologies widespread an extremely important area.
 Purpose – evaluate benefits using CT topometric preparation planning brachytherapy cancer.

Brachytherapy can play a very important role in the definitive cure by radiation therapy in India. However, except for in a handful of centres, the majority of hospitals use it only for intracavitary treatment. The most probable reasons for such are the lack of logistical resources in terms of trained personal and supporting staff, rather than lack of radiotherapy machines and equipment. In thi...

Brachytherapy applications are not restricted to one method only; any method could be combined with another, as well as other radiotherapy techniques. In cervical cancer, intracavitary brachytherapy (ICBT) has been used for practical reasons. Lately though, combination of ICBT and and interstitial brachytherapy (ISBT) techniques are being evaluated in deference to feasibility, practicality and ...

As recommended by the GEC-ESTRO work group, it is important for the 3D image guided CT, or MRI based brachytherapy of cer-A B C D vical cancer to verify what dose is received by 0.1 cm 3 , 1 cm 3 and 2 cm 3 (D 0,1cc , D 1cc and D 2cc , respectively) of the bladder and rectum volume (1). Intracavitary brachytherapy was applied with applicators type Fletcher tandem and ovoids, once a week on a HD...

OBJECTIVES The aim of the study was to estimate acute and late complications of radiation therapy in primary invasive vaginal carcinoma (PIVC) patients. MATERIAL AND METHODS The analysis was performed for the group of 152 PIVC patients given radical radiotherapy in the Krakow Branch of Centre of Oncology during the 1967-2005 period. Twenty five (16.5%) patients in I stage with primary tumour ...

The standard of care for locally advanced carcinoma of uterine cervix is concurrent chemoradiation therapy followed by intracavitary brachytherapy, when there is para-aortic lymphadenopathy, radiation field needs to be extended to para-aortic region. In the latter case dose limiting organs are spinal cord, kidneys and small intestine. We present a challenging case of FIGO IVB squamous cell carc...

PURPOSE To evaluate the toxicity and efficacy of concurrent chemoradiotherapy using weekly cisplatin for patients with locally advanced cervical cancer in East and Southeast Asia, a multi-institutional Phase II clinical study was conducted among eight Asian countries. METHODS AND MATERIALS Between April 2003 and March 2006, 120 patients (60 with bulky Stage IIB and 60 with Stage IIIB) with pr...

Definitive treatment for cervical cancer most often consists of fractionated external beam radiotherapy combined with multi-fraction intracavitary brachytherapy. CT imaging in gynaecological brachytherapy treatment planning has been widely used in the past decade. With the advantages of image-based treatment planning and the commercial treatment planning software tools available, it is possible...
