PURPOSE In the most advanced, non-resectable primary rectal cancers, conventional long-course radiotherapy (RT) (1.8-2Gyx25-28), frequently combined with chemotherapy, has been used since tumour regression is needed in order to allow a radical (R0) resection. In Uppsala, short-course 5x5Gy with planned delayed surgery has been used in patients with(More)
BACKGROUND To address issues regarding the fractionation of radiotherapy (RT) and timing of surgery for rectal cancer, a multicentre trial has randomized patients to preoperative short-course RT with two different intervals to surgery, or long-course RT with delayed surgery. The present interim analysis assessed feasibility, compliance and complications(More)
BACKGROUND AND PURPOSE Few studies have explored the potential clinical advantages of dose escalation and integrated boosts for patients with non-resectable locally advanced rectal cancer. The possibility of escalating dose to non-resectable regions in these patients was the aim of this study. PATIENTS AND METHODS Seven patients with locally very advanced(More)
PURPOSE Accurate delineation of target volumes is important to maximize radiation dose to the tumor and minimize it to nontumor tissue. Computed tomography (CT) and magnetic resonance imaging (MRI) are standard imaging modalities in rectal cancer. The aim was to explore whether functional imaging with F-18 fluorodeoxyglucose (FDG) positron emission(More)
BACKGROUND 5-fluorouracil (5FU) and mitomycin C (MMC)-based chemoradiotherapy (CRT) is standard treatment for anal squamous cell carcinoma. In this phase I study cetuximab was added and the primary aim was to determine the maximum tolerated dose (MTD) of 5FU and MMC in this combination. METHODS AND MATERIALS Patients with locally advanced anal cancer, T2(More)
BACKGROUND Radiotherapy reduces the risk of local recurrence in rectal cancer. However, the optimal radiotherapy fractionation and interval between radiotherapy and surgery is still under debate. We aimed to study recurrence in patients randomised between three different radiotherapy regimens with respect to fractionation and time to surgery. METHODS In(More)
