The cause of involvement of these unusual sites is not clear, but it may be hematological spread, and we want to share these reports such that these sites are seen during follow-up of patients of cancer cervix.
Background: External beam radiotherapy (EBRT) is mainstay of treatment in pa ents with locally advanced cervical carcinoma (LACC). Three dimensional conformal radiotherapy (3DCRT) and intensity modulated radiotherapy (IMRT) are mainly used in EBRT. However which one is superior is s ll controversial. Materials and Methods: Forty pa ents of LACC treated with IMRT were selected for this study. 3DCRT plans were also created for all the pa ents. 3DCRT and IMRT plans were compared on the basis of planning target volume (PTV) coverage, dose to normal organs, homogeneity index (HI) and conformity index (CI 95% ). Results: In both the techniques 99% of PTV was covered with more than 96% of prescribed dose (PD). D 15, D 35 and D 50 (Dose to 15%, 35% and 50% volume respec vely) for bladder was reduced by 2.09%, 14.623% and 32.57% and for the rectum it was reduced by 7.46% ,23.82% and 43.68% in IMRT compared to 3DCRT. V 45 (volume receiving 45 Gy) in case of bowel were found to be much less in IMRT in comparison to 3DCRT. Insignificant difference found between doses to femoral heads in IMRT and 3DCRT. The CI 95% in IMRT plans was found much be:er than that in 3DCRT whereas HI in both the techniques were found almost same. Conclusion: IMRT significantly reduced the irradiated volume of OAR and improved dose conformity in the PTV compared to that by 3DCRT. So, it can be concluded that IMRT should be chosen as preferred technique for the EBRT of LACC with proper immobilizing devices and imaging.
Patients with breast and head and neck cancer have a higher risk of developing SPM. The possibility of SPM should be considered and excluded during pretreatment evaluation and during follow-up of treated cancer patients.
Adenoid cystic carcinoma (ACC) of the trachea is rare; it represents 1% of all respiratory tract cancers. It is generally considered as a slow-growing, with prolonged clinical course. Most patients present with dyspnea, and the symptoms often mimic those of asthma or chronic bronchitis. Surgical resection is the mainstay of treatment often combined to radiotherapy because of close surgical margins. When surgery is not possible, most tumors respond to radiotherapy alone which often results in long periods of remission. There is no consensus on the best treatment for locally advanced inoperable ACC of trachea. This case report describes a 51-year-old woman unresectable ACC of trachea due to comorbid conditions, successfully managed by intensity modulated radiotherapy. At 8 months follow-up, the patient is healthy and asymptomatic.
Background: For chest wall irradiation in breast cancer patients, three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT) have made tremendous changes in treatment delivery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
