Effect of epoetin alfa on survival and cancer treatment-related anemia and fatigue in patients receiving radical radiotherapy with curative intent for head and neck cancer.PURPOSE: To evaluate the effect of epoetin alfa on local disease-free survival (DFS), overall survival (OS), and cancer treatment-related anemia and fatigue in patients with head and neck cancer receiving radical radiotherapy with curative intent. PATIENTS AND METHODS: Patients (N = 301) with hemoglobin (Hb) less than 15 g/dL were randomly assigned in a ratio of 1:1 to receive radiotherapy plus epoetin alfa (10,000 U subcutaneously [SC] three times weekly if baseline Hb was < 12.5 g/dL; 4,000 U SC three times weekly if baseline Hb > or = 12.5 g/dL) or radiotherapy alone. Hb levels were monitored weekly. The primary end point was local DFS, defined as the time from random assignment to local disease recurrence or death. Secondary efficacy end points included OS, local tumor response, and local tumor control. Patients were followed at 1, 4, 8, and 12 weeks postradiotherapy and annually for 5 years. Cancer treatment-related anemia and fatigue were evaluated with the Functional Assessment of Cancer Therapy-Anemia and Functional Assessment of Cancer Therapy-Head and Neck. Adverse events were recorded up to 12 weeks postradiotherapy. RESULTS: Hb levels increased from baseline with epoetin alfa. The median duration of local DFS was not statistically different between groups (observation, 35.42 months; epoetin alfa, 31.47 months; hazard ratio, 1.04; 95% CI, 0.77 to 1.41). Groups did not significantly differ in DFS, OS, tumor outcomes, or cancer treatment-related anemia or fatigue. No new or unexpected adverse events were observed. CONCLUSION: Addition of epoetin alfa to radical radiotherapy did not affect survival, tumor outcomes, anemia, or fatigue positively or negatively in patients with head and neck cancer.
Irinotecan+5-fluorouracil with concomitant pre-operative radiotherapy in locally advanced non-resectable rectal cancer: a phase I/II study.In the UK, 10% of patients diagnosed with rectal cancer have inoperable disease at presentation. This study ascertained whether the resectability rate of inoperable locally advanced rectal cancer was improved by administration of intravenous irinotecan, 5-fluorouracil (5-FU) and pelvic radiotherapy. During phase I of the trial (n=12), the dose of irinotecan was escalated in three-patient cohorts from 50 mg m(-2) to 60 mg m(-2) to 70 mg m(-2) to identify the maximum tolerated dose (60 mg m(-2)). In phase II, 31 patients with non-resectable disease received 45 Gy radiotherapy and 5-FU infusions (200 mg m(-2) per day) for 5 weeks. Irinotecan (60 mg m(-2)) was given on days 1, 8, 15 and 22. After treatment, patients were operated on if possible. Thirty patients completed the protocol, 28 underwent surgery. Before surgery, MRI restaging of 24 patients showed that 19 (79%) had a reduction in tumour stage after treatment (seven complete clinical response and 12 partial). Of 27 patients followed up after surgery, 22 (81%) had clear circumferential resection margins. Disease-free and overall survival estimates at 3 years were 65 and 90%, respectively. The regimen was well tolerated. Irinotecan, 5-FU and radiotherapy results in tumour downgrading, allowing resection of previously inoperable tumour with acceptable toxicity.
Preoperative chemoradiotherapy using concurrent capecitabine and irinotecan in magnetic resonance imaging-defined locally advanced rectal cancer: impact on long-term clinical outcomes.To assess long-term clinical outcomes of preoperative chemoradiotherapy of magnetic resonance imaging (MRI)-defined locally advanced rectal adenocarcinoma using concurrent irinotecan and capecitabine.
Synchronous chemoradiotherapy in patients with locally advanced squamous cell carcinoma of the head and neck using capecitabine: a single-centre, open-label, single-group phase II study.To evaluate the efficacy of concurrent oral capecitabine with accelerated hypofractionated radical radiotherapy in locally advanced squamous cell carcinoma of the head and neck (SCCHN).
