Radiation pneumonitis and pulmonary function with lung dose–volume constraints in breast cancer irradiation
PURPOSE We studied symptomatic radiation pneumonitis (RP) and changes in pulmonary function tests (PFTs) after loco-regional radiotherapy (LRRT) with V20 lung constraints in breast cancer (BC). PATIENTS AND METHODS Sixty-four women underwent PFTs before and 5 months after 3D planned LRRT for BC. The incidentally irradiated ipsilateral lung V20 was minimised to <30%. Patients were monitored fo...
متن کاملRadiation pneumonitis after hypofractionated radiotherapy: evaluation of the LQ(L) model and different dose parameters.
PURPOSE To evaluate the linear quadratic (LQ) model for hypofractionated radiotherapy within the context of predicting radiation pneumonitis (RP) and to investigate the effect if a linear (L) model in the high region (LQL model) is used. METHODS AND MATERIALS The radiation doses used for 128 patients treated with hypofractionated radiotherapy were converted to the equivalent doses given in fr...
متن کاملRisk factors for radiation pneumonitis caused by whole breast irradiation following breast-conserving surgery.
We evaluated risk factors of radiation pneumonitis (RP) after whole breast irradiation following breast-conserving surgery. Four hundred and seventy-two cases underwent whole breast irradiation with tangential field following breast-conserving surgery in our hospital, between January 2005 and April 2007. Of these cases, we performed statistical analyses for 423 breasts of 413 patients, using a ...
متن کاملWeight of Risk Factors for Adjusting Capitation in Primary Health Care: A Systematic Review
Background: Capitation payment is the best-known strategy for paying providers in primary health care. Since health care needs and personal characteristics play an essential role in health care utilization and resource spending, there is a growing tendency on risk adjustment models among health researchers. The objective of this systematic review was to examine the weights used for risk adjust...
متن کاملReduction of radiation pneumonitis by V20-constraints in breast cancer
INTRODUCTION Adjuvant local-regional radiotherapy (LRRT) is routinely recommended for breast cancer patients. It is well known being related to pulmonary side-effects. We studied post-RT radiological changes on X-ray and CT, and correlated the findings with Quality of Life (QoL), common dosimetric factors and co-variates. The results were compared with a previously reported cohort of 137 irradi...
