A randomised trial of radiotherapy compared with cisplatin chemo-radiotherapy in patients with unresectable squamous cell cancer of the esophagus.

BACKGROUND AND PURPOSE: Following our phase II experience, a randomised trial was undertaken to evaluate the efficacy of adding chemotherapy to radiotherapy in patients with unresectable squamous cell cancer of the esophagus. PATIENTS AND METHODS: Patients randomised to the RT group received 50 Gy/25 fx/5 weeks of teletherapy followed 1-2 weeks later with 12 Gy/2 fx of high-dose-rate intra-lumenal brachytherapy spaced a week apart. Following the first 3 years of recruitment, due to unexpected late morbidity, brachytherapy was excluded and the protocol modified to 66 Gy/33 fx/6.5 weeks. The CRT group received identical radiotherapy with concurrent weekly cisplatin at 35 mg/m(2) for 6-7 cycles. RESULTS: Between April 1999 and December 2005, 125 patients were randomised to a RT (n=60) or CRT group (n=65). Radiotherapy treatment was completed in 78% (47/60) of the RT group and 89% (58/65) of the CRT group (P=0.10). Six or more cycles of cisplatin could be delivered in 63% (41/65), which resulted in RTOG grade 3 neutropenia of 3%. Late morbidity in the form of ulcers (5% vs. 15% odds ratio 0.29, 95% CI 0.08-1.11, P=0.08) and strictures (13% vs. 28%, odds ratio 0.40, 95% CI 0.16-1.01, P=0.05) was observed in the RT and CRT groups, respectively. At a median follow up of 23 months of all patients alive (range 6-82 months) and with 95/125 events, the median, 1, 2 and 5 year projected survival was 7.1 months, 32.3%, 22.8% and 13.7% vs. 13.4 months, 57.6%, 38.9% and 24.8% for the RT and CRT groups, respectively (hazard ratio 0.65, 95% CI 0.44-0.98, P=0.038). CONCLUSIONS: The addition of concurrent cisplatin to radiotherapy resulted in a modest improvement in survival and was associated with manageable additional acute and late morbidity.

Treatment of small cell lung cancer with VP-16, vincristine, doxorubicin (Adriamycin), cyclophosphamide (EVAC), and high-dose chest radiotherapy

Seventy-one previously untreated patients with small cell lung cancer (SCLC) received a combination of VP-16, vincristine, doxorubicin (Adriamycin), and cyclophosphamide (EVAC) repeated every three weeks. Limited-disease (LD) patients and extensive-disease (ED) patients achieving a complete response (CR) or partial response (PR) after four to six cycles of EVAC received 4,000 rads over four weeks whole-brain radiotherapy (RT) and 5,000 rads over five weeks RT to the original pulmonary primary and mediastinum. ED patients with persisting disease outside the chest after six cycles of EVAC continued chemotherapy and did not receive RT. After RT was completed, EVAC was continued for a total treatment duration of 24 months. Of 65 patients evaluable for response 76% (25 of 33) of LD patients and 34% (11 of 32) of ED patients achieved a CR prior to RT; two additional ED patients achieved a CR after RT. Median survival for all 71 patients was 48 weeks (range, one to 207 weeks); median survival for 33 LD patients was 92 weeks and for 38 ED patients it was 36 weeks. Nine of 25 LD patients and 10 of 13 ED patients have relapsed from CR. The EVAC-RT protocol is promising in view of the high CR rate and long remission duration achieved, especially among patients with LD.     

Comparison of granulocyte-macrophage colony-stimulating factor and sucralfate mouthwashes in the prevention of radiation-induced mucositis: a double-blind prospective randomized phase III study

PURPOSE: To compare granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwashes with sucralfate mouthwashes in the prevention of radiation-induced mucositis. METHODS AND MATERIALS: Forty patients with radically operated head-and-neck cancer were randomly allocated to use either GM-CSF (n = 21) or sucralfate (n = 19) mouthwashes during postoperative radiotherapy (RT). All patients received conventionally fractionated RT to a total dose of 50-60 Gy in 2-Gy daily fractions during 5-6 weeks to the primary site and regional lymphatics. A minimum of 50% of the oral cavity and oropharyngeal mucosa was included in the clinical target volume. GM-CSF mouthwashes consisted of 37.5 microg GM-CSF and sucralfate mouthwashes of 1.0 g of sucralfate distilled in water. Both washes were used 4 times daily, beginning after the first week of RT and continued to the end of the RT course. Symptoms related to radiation mucositis and body weight, serum prealbumin level, and blood cell counts were monitored weekly. RESULTS: Oral mucositis tended to be less severe in the GM-CSF group (p = 0.072). Complete (n = 1) or partial (n = 4) healing of mucositis occurred during the RT course in 5 patients (24%) in the GM-CSF group and in none of the patients in the sucralfate group (p = 0.049). Patients who received GM-CSF had less mucosal pain (p = 0.058) and were less often prescribed opioids for pain (p = 0.042). Three patients in the sucralfate group needed hospitalization for mucositis during RT compared with none in the GM-CSF group. Four patients (21%) in the sucralfate group and none in the GM-CSF group required an interruption in the RT course (p = 0.042). No significant differences in weight, prealbumin level, or blood cell count were found between the groups, and both mouthwashes were well tolerated. CONCLUSION: GM-CSF mouthwashes may be moderately more effective than sucralfate mouthwashes in preventing radiation-induced mucositis and mucositis-related pain, and their use may lead to less frequent RT course interruptions from mucositis. The present findings need to be confirmed before adopting GM-CSF mouthwashes in routine clinical use.

Phase I Study of Topotecan in Combination with Concurrent Radiotherapy in Adults with Glioblastoma

A phase I study was performed to determine the maximum tolerated dose and the recommended dose of continuous intravenous infusion of topotecan in combination with radiotherapy (RT) in patients with previously untreated glioblastoma multiforme (GBM). Twenty patients with histologically proven GBM and 1 with rhabdoid tumor were enrolled. After surgery or stereotactic biopsy, patients received cranial RT (60 Gy/30 fractions/40 days) and 3 cycles of topotecan as continuous infusion (CIV) from day 1 to 5 on weeks 1, 3, and 5 during RT. The dose of topotecan was escalated from 0.6 to 1.0 mg/m2/day. Four dose levels were tested. One grade 4 thrombocytopenia was seen at level 1 (topotecan dose 0.6 mg/m2/day; 6 patients). No dose-limiting toxicity was seen at level 2 (0.8 mg/m2/day; 3 patients) or an intermediate level of 2 bis (0.9 mg/m2/day; 6 patients). Six patients were included at level 3 (1.0 mg/m2/day), 4 of whom experienced dose-limiting toxicities, including 3 episodes of grade 4 thrombocytopenia, 1 platelet transfusion, 1 febrile neutropenia, and 1 grade 4 neutropenia of more than 7 days. Eighty percent of patients with GBM were alive at 12 months. The dose-limiting toxicity of topotecan administered as CIV for 5 days every 2 weeks is hematological. The maximum tolerated dose is 1.0 mg/m2/day and the recommended dose is 0.9 mg/m2/day. A phase II trial using the recommended dose of topotecan is ongoing.     

Adjuvant paclitaxel and carboplatin chemotherapy with involved field radiation in advanced endometrial cancer: a sequential approach

PURPOSE: To determine the feasibility of adjuvant paclitaxel and carboplatin chemotherapy interposed with involved field radiotherapy for women with advanced endometrial cancer. METHODS AND MATERIALS: This was a prospective cohort study of women with Stage III and IV endometrial cancer. Adjuvant therapy consisted of 4 cycles of paclitaxel (175 mg/m(2)) and carboplatin (350 mg/m(2)) every 3 weeks, followed sequentially by external beam radiotherapy (RT) to the pelvis (45 Gy), followed by an additional two cycles of chemotherapy. Para-aortic RT and/or HDR vault brachytherapy (BT) were added at the discretion of the treating physician. RESULTS: Thirty-three patients (median age, 63 years) received treatment between April 2002 and June 2005. Median follow-up was 21 months. Stage distribution was as follows: IIIA (21%), IIIC (70%), IVB (9%). Combination chemotherapy was successfully administered to 30 patients (91%) and 25 patients (76%), before and after RT respectively. Nine patients (27%) experienced acute Grade 3 or 4 chemotherapy toxicities. All patients completed pelvic RT; 19 (58%) received standard 4-field RT and 14 (42%) received intensity-modulated radiotherapy. Ten (30%) received extended field radiation. Four patients (12%) experienced acute Grade 3 or 4 RT toxicities. Six (18%) patients developed chronic RT toxicity. There were no treatment-related deaths. Two-year disease-free and overall survival rates were both 55%. There was only one pelvic relapse (3%). CONCLUSIONS: Adjuvant treatment with combination chemotherapy interposed with involved field radiation in advanced endometrial cancer was well tolerated. This protocol may be suitable for further evaluation in a clinical trial.     

A phase II trial of accelerated radiotherapy using weekly stereotactic conformal boost for supratentorial glioblastoma multiforme: RTOG 0023

PURPOSE: This phase II trial was performed to assess the feasibility, toxicity, and efficacy of dose-intense accelerated radiation therapy using weekly fractionated stereotactic radiotherapy (FSRT) boost for patients with glioblastoma multiforme (GBM). METHODS AND MATERIALS: Patients with histologically confirmed GBM with postoperative enhancing tumor plus tumor cavity diameter <60 mm were enrolled. A 50-Gy dose of standard radiation therapy (RT) was given in daily 2-Gy fractions. In addition, patients received four FSRT treatments, once weekly, during Weeks 3 to 6. FSRT dosing of either 5 Gy or 7 Gy per fraction was given for a cumulative dose of 70 or 78 Gy in 29 (25 standard RT + 4 FSRT) treatments over 6 weeks. After the RT course, carmustine (BCNU) at 80 mg/m(2) was given for 3 days, every 8 weeks, for 6 cycles. RESULTS: A total of 76 patients were analyzed. Toxicity included: 3 Grade 4 chemotherapy, 3 acute Grade 4 radiotherapy, and 1 Grade 3 late. The median survival time was 12.5 months. No survival difference is seen when compared with the RTOG historical database. Patients with gross total resection (41%) had a median survival time of 16.6 months vs. 12.0 months for historic controls with gross total resection (p = 0.14). CONCLUSION: This first, multi-institutional FSRT boost trial for GBM was feasible and well tolerated. There is no significant survival benefit using this dose-intense RT regimen. Subset analysis revealed a trend toward improved outcome for GTR patients suggesting that patients with minimal disease burden may benefit from this form of accelerated RT.     

A randomized trial of induction chemotherapy plus concurrent chemoradiotherapy versus induction chemotherapy plus radiotherapy for locoregionally advanced nasopharyngeal carcinoma

The aim of this randomized study was to compare the efficacy of induction chemotherapy plus concurrent chemoradiotherapy (IC+CCRT) versus induction chemotherapy plus radiotherapy (IC+RT) for patients with locoregionally advanced nasopharyngeal carcinoma. From August 2002 to April 2005, 408 patients were randomly divided into two groups: an IC+CCRT group and an IC+RT group. Patients in both groups received the same induction chemotherapy: two cycles of floxuridine (FuDR)+carboplatin (FuDR, 750mg/m(2), d1-5; carboplatin, area under the curve [AUC]=6). The patients received radiotherapy 1week after they finished the induction chemotherapy. The patients in the IC+CCRT group also received carboplatin (AUC=6) on days 7, 28, and 49 of radiotherapy. Eight patients did not meet the inclusion criteria, and the remaining 400 cases were analyzed. Grade III or IV toxicity was found in 28.4% of the patients in the IC+CCRT group and 13.1% of those in the IC+RT group (P<.001). Five-year overall survival rates were 70.3% and 71.7% (P=0.734) in the IC+CCRT and IC+RT groups, respectively. No significant differences in failure-free survival, locoregional control, and distant control were found between the two groups. Compared with the IC+RT program, the IC+CCRT program used in the present study did not improve the overall survival and failure-free survival in patients with locoregionally advanced nasopharyngeal carcinoma. Using carboplatin in the concurrent chemoradiotherapy was not suitable for nasopharyngeal carcinoma.
