Arm lymphoedema is a frequent complication after breast cancer treatment. Early diagnosis and treatment is considered important for successful management of breast cancer related arm lymphoedema (BCRL). The purpose was to identify BCRL incidence, time of onset, progression/regression and associated factors 10 years after breast cancer diagnosis. ⋯ BCRL can be identified at an early stage both in regard to time of diagnosis after operation and to edema volume, and that edema volume can be kept at a low level for at least 10 years. Small LRV at time of diagnosis appears to be more important for minimizing the progression of LRV than time of diagnosis after operation.

The use of Intensity-modulated radiotherapy (IMRT) and Helical tomotherapy (HT) is increasing in gynecological cancer patients. No published studies have performed a dosimetric evaluation of whole pelvic radiotherapy (WPRT) using HT for postoperative endometrial cancer. The purpose of this study was to perform a direct dosimetric comparison of three-dimensional conformal radiotherapy (3D-CRT), IMRT and HT plans for WPRT in postoperative endometrial cancer patients, and to evaluate the integral dose to organs at risk (OARs) and normal tissue. ⋯ In postoperative WPRT of endometrial cancer, IMRT and HT result in better conformity and lower integral dose to OARs compared with 3D-CRT. The integral dose to normal tissue did not increase significantly in IMRT, although a greater volume of normal tissue is irradiated to the dose below 10 Gy. HT further improves the dose homogeneity and integral dose to rectum and bladder, at the expense of a slightly higher integral dose to pelvic bones and normal tissue.
