Clinical TrialPhase I study of 5-fluorouracil and leucovorin by continuous infusion chronotherapy and pelvic radiotherapy in patients with locally advanced or recurrent rectal cancer.
To determine the maximal tolerated dose of chronomodulated 5-fluorouracil (5-FU) and leucovorin (LV) given concurrently with radiotherapy in patients with rectal cancer. ⋯ Preoperative chemoradiotherapy in rectal cancer using chronomodulated 5-FU and LV is feasible. The recommended Phase II dose is 5-FU 200 mg/m2 and LV 20 mg/m2 daily for 5 weeks.

Hypofractionated external beam radiotherapy as retreatment for symptomatic non-small-cell lung carcinoma: an effective treatment?
To evaluate prospectively the efficacy, toxicity, and duration of the palliative effect of retreatment with external beam radiotherapy in symptomatic patients with recurrent non-small-cell lung cancer. ⋯ External beam hypofractionated reirradiation can be effective as a palliative treatment for local complaints in non-small-cell lung cancer. The complication rate of reirradiation was acceptably low.

ReviewSalvage radiotherapy for palpable, locally recurrent prostate cancer after radical prostatectomy.
A retrospective study to evaluate the outcome of salvage radiotherapy (RT) for clinically apparent, palpable prostate cancer recurrence after radical prostatectomy (RP). ⋯ Salvage prostate bed RT for clinically apparent locally recurrent prostate cancer after RP provides effective local tumor control with modest durable biochemical control. Patients irradiated with a better simulation technique were found to have a more favorable outcome. A consensus on a definition of biochemical disease-free survival after salvage RT is critical for meaningful comparison of the available data and to future progress in treating this disease process.

Interval between surgery and radiotherapy: effect on local control of soft tissue sarcoma.
To evaluate the clinical significance of the interval between surgery and postoperative radiotherapy (RT) for patients with soft tissue sarcoma. ⋯ The interval between surgery and RT did not significantly impact the 10-year LC rate. These findings indicate that an RT delay should not be viewed as an independent adverse factor for LC and that treatment intensification may not be necessary for patients in whom a treatment delay has already occurred.
