A phase II study of oxaliplatin with 5-FU/folinic acid and concomitant radiotherapy as a preoperative treatment in patients with locally advanced rectal cancer

Objective: To evaluate the activity and safety of adding oxaliplatin to a standard chemoradiotherapy schema, including 5-fluorouracil (5-FU)/folinic acid (FA), in locally-advanced rectal cancer (LARC). Methods: Two cycles of oxaliplatin 130 mg/m2 plus FA 20 mg/m2 bolus for 5 days and 5-FU 350 mg/m2 continuous infusion for 5 days were given during week 1 and 4 of pelvic radiotherapy 46 Gy. Patients with a T3/4 and/or node-positive rectal tumour were eligible. Surgery was performed 4–6 weeks after radiotherapy. The primary endpoint was to determine the rate of pathological response. Secondary endpoints were to assess the rate of clinical response and the safety profile. Results: Between March 2005 and January 2009, a total of 35 patients were enrolled. The pathological downstaging rate was 79% with a pathological complete response rate of 17%. The overall clinical response rate (assessed by computed tomography or transrectal ultrasound) was 77%. Grade 3 diarrhoea and Grade 3 neutropaenia were reported in 14% and 11% of the patients, respectively. Eleven patients did not undergo surgery: four of them refused the operation, and seven patients were inoperable due to disease progression. In 24 patients who had surgery, a sphincter-preserving procedure could be performed in 29%. At the median follow-up time of 28.1 months, 25 patients (71%) survived with no evidence of disease. Conclusion: The promising results in terms of pathological response, and the associated good safety profile of a regimen of oxaliplatin plus 5-FU/FA with concomitant radiotherapy, suggest that the regimen could be used in LARC.

Phase II study of concurrent chemoradiotherapy for inoperable (bulky) stage III (A/B) non-small cell lung cancer (NSCLC): a preliminary report.

We designed a phase II study to determine the feasibility and toxicity of concomitant radiotherapy and Paclitaxel/Carboplatin followed by adjuvant chemotherapy of the same regimen in patients with newly diagnosed inoperable stage III A/B non-small cell lung cancer. Patients were irradiated with a total dose of 66 Gy. Weekly courses of Paclitaxel 45 mg/m2 and Carboplatin AUC 2 were administered intravenously during the irradiation period. After completion of concurrent chemoradiotherapy, adjuvant chemotherapy with Paclitaxel 175 mg/m2 and Carboplatin AUC 6 intravenously every 3 weeks for 4 cycles were given. Since March 1998, 15 patients have been enrolled. All patients were assessable for efficacy and toxicity after concurrent chemoradiotherapy. Eleven patients were assessable for efficacy and toxicity after adjuvant chemotherapy. After concomitant chemoradiotherapy, complete response (CR) was documented in 2 of 15 (13%). Partial response (PR) was documented in 9 of 15 (60%). After completion of adjuvant chemotherapy in 11 patients, the overall response rate was 91 per cent. (18% CR, 73% PR). There were 8 per cent gr. 3-4 neutropenia which occurred during adjuvant chemotherapy. Concomitant Paclitaxel/Carboplatin and radiotherapy are promising modalities in the treatment of inoperable stage III A/B non-small cell lung cancer.

Carcinoma of the nasopharynx in Chiang Mai University Hospital: a review of 205 cases.

Carcinoma of the nasopharynx is one of the common head and neck cancers in Southeast Asia. We had studied 205 cases of nasopharyngeal cancer who attended the ENT clinic of the Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand from 1980-1984. The majority of the patients were found in stage IV. One hundred and five patients received a curative dose of radiation therapy. The observed actuarial 5 year survival was 34 per cent. There was a significant decrease in survival of patients with T4 disease. Differences in age, sex, histopathology and N-stage did not affect the survival. So far, the only specific treatment we can offer patients is radiation therapy, so an earlier diagnosis must be established in order to get better results of treatment.
