Abstract
In the early 1990s, when conventional radiotherapy (RT) was the standard of care in patients with locally advanced head and neck squamous cell carcinoma (HNSCC), two main options were being tested to improve the efficacy and the therapeutic ratio of RT. The first approach evaluated the effect of adding chemotherapy (CT) simultaneously to RT (RT-CT), while the second approach assessed the effect of modified fractionated RT. To answer these two questions, in 1994, the French Group for Head and Neck Oncology Radiotherapy (GORTEC) initiated two randomized trials. A total of 494 patients were entered in these two parallel phase III multicenter trials comparing conventional RT (70 Gy in 35 fractions) either with concomitant RT-CT (226 patients; 70 Gy in 35 fractions with three cycles of a 4-day regimen comprising carboplatin and 5-fluorouracil [5FU]) or with very accelerated RT (268 patients) delivering 64 Gy in 3 weeks. The 5-year overall survival (OS), specific disease-free survival (DFS), and local-regional control rates were improved in favor of simultaneous RT-CT, whereas local-regional control was significantly improved with accelerated RT, along with a marginal effect on OS and DFS. This increased antitumor efficacy was in both cases associated with a marked increase in acute RT-induced toxicity, which was more pronounced with accelerated RT, whereas late effects were marginally increased with the addition of CT and not influenced by accelerated RT. We conclude that both concomitant RT-CT and accelerated RT improved tumor control rates, as compared to conventional RT, along with increased but manageable toxicity. The two regimens are currently being tested in an ongoing randomized study and also being compared to moderately accelerated RT and concomitant CT.

Abstract
This phase II study evaluated docetaxel-5-fluorouracil (5-FU) in locally recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Patients were divided into 2 cohorts--those previously treated with chemotherapy and those nonpretreated--that received docetaxel 75 mg/m2 (day 1) plus 5-FU 1,000 mg/m2/day (days 1-5 every 3 weeks). Of 63 patients entered, 20 (31.7%) were pretreated and 43 (68.3%) were nonpretreated. Fifty-nine patients (93.7%) had received prior radiotherapy. After inclusion of 20 patients, the 5-FU dose was reduced to 750 mg/m2/day due to unacceptable toxicity. The overall response rate (ORR) was 20.6% on radiologic review (22.2%, investigator assessment). Pretreated patients achieved an ORR of 25.0% versus 18.6% for nonpretreated patients. This unexpected finding was partly attributed to differences in patient characteristics between the groups. Overall major grade 3 to 4 toxicities comprised neutropenia (66.6%), febrile neutropenia (31.7%), and mucositis (31.7%). Grade 3 to 4 toxicities were lower at the reduced 5-FU dose (750 mg/m2/day): Febrile neutropenia declined from 40.0% to 27.9%; mucositis declined from 55.0% to 20.9%. Three treatment-related deaths occurred (2 with 5-FU 750 mg/m2/day, 1 with 5-FU 1,000 mg/m2/day). Docetaxel-5-FU appears active in locally recurrent and/or metastatic SCCHN with acceptable toxicity at the dose of 5-FU 750 mg/m2.

Abstract
In breast cancer, radiation therapy improves local control rate and survival. When chemotherapy and radiation are indicated the sequencing of the two treatments is still controversial. Several studies have suggested that adjuvant radiotherapy could be safely delayed until adjuvant chemotherapy was completed. Other studies, most of them retrospective, pointed out that a delay in the initiation of radiotherapy to give chemotherapy first, will result in a increased rate of local recurrence. Concomitant administration of the two treatments is an alternative. Pilot studies have suggested the feasibility of simultaneous administration using selected regimen as CMF or FNC. A randomized phase III trials has been conducted to compare sequential treatment with chemotherapy first and radiation versus concomitant treatments. Preliminary results of this study are presented.

Abstract
The European Organisation for Research and Treatment of Cancer (EORTC) 22921 four-arm randomised trial questioned the value of preoperative chemoradiation (XRT-CT) versus preoperative radiation (XRT) and the value of additional postoperative chemotherapy (CT) versus none in T3-T4 M0 resectable rectal cancer patients. We report on the preoperative toxicity, treatment compliance and early deaths (all deaths up to 30 days after surgery) of the two treatment modalities in patients who were entered into trial before January 2001. In the XRT Group (group A), patients received 45 Gy, 25 fractions over 5 weeks. In the XRT-CT Group (group B), two 5-day courses of CT were added to the first and fifth weeks of XRT. For each CT course: 5-fluorouracil (5-FU) 350 mg/m2/day and Leucovorin (LV) 20 mg/m2/day were given. 398 and 400 patients started treatment in groups A and B, respectively. Grade 2+acute diarrhoea occurred in 17.3 and 34.3% of patients in groups A and B, respectively (P<0.005). The other side-effects remained unchanged or were only marginally increased. The compliance with RT was 98.5 and 95.5% in groups A and B, respectively. In group B, 78.7 and 71.1% of the patients received 95-105% of the planned CT doses at the first and second courses, respectively. 6 patients died preoperatively, 2 from toxicity in group B. 8 patients (1%) died within the 30 days after surgery in both groups. At the doses recommended in the protocol, the addition of 5-FU-LV to preoperative XRT slightly increased the amount of acute toxicity. However, the compliance with the radiation protocol or the feasibility of surgery did not decrease.

Abstract
After breast-conservative surgery, radiation therapy delivered to the whole breast to 50 Gy with an additional boost of 10 to 16 Gy is the standard of care. Based upon data showing that the vast majority of the recurrences occur within and surrounding the original tumor site and in order to reduce the morbidity of whole breast radiotherapy and to give the treatment in a shorter time, partial breast irradiation has been developed by several institutions. Partial breast radiotherapy is given by intraoperative radiotherapy (photons or electrons), or brachytherapy (low dose rate or high dose rate) or external radiotherapy using 3D conformal radiation therapy. This is a review of the literature data on this topic.

Abstract
The esophagus is divided into four regions: cervical esophagus, intrathoracic esophagus with upper, mid and lower thoracic portion. Cancer may occur on each of these regions. Computed tomography of the thorax and superior abdomen and endoscopic ultrasound are necessary for reliable staging. CT simulation allows accurate definition of tumor volume. GTV includes tumor volume and regional lymph nodes. CTV encompasses GTV plus safety margin and lymph nodes areas considered to harbor potential microscopic disease. The extent of prophylactic lymph node irradiation depends on the anatomic location of the primary tumor.

Abstract
Despite surgery, post-operative irradiation and adjuvant conventional chemotherapy, prognosis of high-grade gliomas remains poor. Carmustine (BCNU) has been shown to have limited activity at conventional dosage but is still the standard chemotherapy. Activity of chemotherapy is limited by the blood-brain barrier impermeability and high levels of expression of multidrug resistance proteins on tumor and/or endothelial cells. Despite high response rates, development of intra-arterial chemotherapy remains limited because of frequent acute brain toxicity related to drug administration. High-dose intravenous chemotherapy rescued by autologous hemopoietic stem cell transplantation is an alternative that might increase drug delivery through the blood-brain barrier and tumor control. Several phase I-II trials using high-dose BCNU were published. The maximum tolerated dose seems to be 800 mg/m2 and interstitial pneumonitis and hepatitis are dose-limiting toxicities. Few phase I-II trials of high-dose therapy were published using drug combinations. High response rates in patients with progressive tumor were observed and in adjuvant setting, encouraging results in terms of median survival time and long survivors were published. No phase III trial was reported to date. Future investigations should include randomized trials comparing high-dose and conventional-dose chemotherapy and development of new high-dose regimens that incorporate new drugs such as temozolomide.

Abstract
This comparative phase III trial of mitoxantrone+vinorelbine (MV) versus 5-fluorouracil+cyclophosphamide+either doxorubicin or epirubicin (FAC/FEC) in the treatment of metastatic breast cancer was conducted to determine whether MV would produce equivalent efficacy, while resulting in an improved tolerance in relation to alopecia and nausea/vomiting. This multicentre study recruited and randomised 281 patients with metastatic breast cancer; 280 were evaluable for response survival and toxicity (138 received FAC/FEC, 142 received MV). Patient characteristics were matched in each arm and stratification for prior exposure to adjuvant therapy was made prospectively. The overall response rate (ORR) was equivalent in the two arms (33.3% for FAC/FEC versus 34.5% for MV), but MV was more effective in patients who had received prior adjuvant therapy (13% (95% confidence interval (CI) 3-23) for FAC/FEC versus 33% (95% CI 20-47) for MV P=0.025) with a better progression-free survival (PFS) (5 months (range 1-18 months) versus 8 months (range 1-27 months); P=0.0007 for FAC/FEC versus MV, respectively) while FAC/FEC was more effective in previously untreated patients (ORR 43% (95% CI 33-53) versus 35% (95% CI 25-45), P=0.26; PFS 9 months (range 0-29 months) versus 6 months (range 0-26 months) P=0.014). Toxicity was monitored through the initial six cycles of therapy; febrile neutropenia and delayed haematological recovery was more frequent for MV (P=0.001), while nausea/vomiting of grades 3-4 was greater for FAC/FEC (P=0.031), as was alopecia (P=0.0001), cardiotoxicity was the same for the two regimens. MV represents a chemotherapy combination with equivalent efficacy to standard FAC/FEC and improved results for patients who have previously received adjuvant chemotherapy. Toxicity must be balanced to allow for increased haematological suppression and risk of febrile neutropenia with MV compared with a higher risk of subjectively unpleasant side-effects such as nausea/vomiting and alopecia with FAC/FEC.

Abstract
PURPOSE To evaluate the relationship between the number of positive nodes and probabilities of locoregional control and survival in patients with invasive squamous cell carcinomas of the oral cavity and oropharynx. MATERIAL AND METHODS Between 1976 and 1993, we treated with curative intent 183 patients (median age: 56 years; standard deviation: 10 years). Seventy-nine patients (43%) had oropharyngeal primary invasive carcinoma and 104 (57%) had oral cavity (excluding the lip) primary invasive carcinoma. Patients with simultaneous primary lesion or visceral metastases were excluded from the analysis. All the patients had neck dissection with at least six nodes to analyse. One-hundred fifty-nine patients (87%) underwent resection of the primary lesion and 158 (86%) were treated postoperatively with external beam irradiation alone or combined with interstitial implant (median dose: 60 Gy; standard deviation: 10 Gy). Average follow-up was 52 months. RESULTS The overall 5-year survival rate using the Kaplan-Meier method was 42.6%. The 5-year survival rates were 60.0% when lymph nodes were histologically negative, 39.5% when one lymph node was positive, 28.0% when two lymph nodes were positive and 24.4% when three or more lymph nodes were positive (P = 0.0004). The number of positive nodes did not significantly influence the specific disease-free survival and locoregional control rates. CONCLUSION Patients with one or more positive neck nodes must have postoperative treatment.

Abstract
BACKGROUND The topoisomerase II-targeted drugs, epipodophyllotoxins and anthracyclines, have been shown to induce therapy-related AML (t-AML) characterized by a short latency period after chemotherapy, the absence of prior myelodysplastic syndrome and stereotyped chromosome aberrations. Few reports have been published on patients treated with the anthracenedione mitoxantrone which also targets topoisomerase II. We observed 10 cases of such t-AML over a 7-year-period in breast cancer patients treated with mitoxantrone combined with fluorouracil, cyclophosphamide and regional radiotherapy, and in three cases with vindesine. PATIENTS AND METHODS We retrospectively analyzed patients referred to our hospital for AML with a past history of polychemotherapy for breast cancer, including mitoxantrone, either as adjuvant (8 patients)/neoadjuvant (1 patient) therapy or for metastatic disease (1 patient). We studied the probability of developing t-AML in a prospective series of 350 patients treated with an adjuvant FNC regimen (mitoxantrone, fluorouracil, cyclophosphamide) and radiation therapy. RESULTS The median age was 45 years (range 35-67). t-AML developed 13-36 months (median 16) after beginning chemotherapy for breast cancer, and 4-28 months (median 10.5) after ending treatment. As described in t-AML following treatment with epipodophyllotoxins or anthracyclines, we found a majority of FAB M4, M5 and M3 phenotypes (7 of 10), and characteristic karyotype abnormalities that also can be found in de novo AML: breakpoint on chromosome 11q23 (3 patients), inv(16)(p13q22) (2 patients), t(15;17)(q22;q11) (1 patient), t(8;21)(q22;q22) (1 patient) and del(20q)(q11) (1 patient). The prognosis was poor. All patients died of AML shortly after diagnosis. Since two patients had been enrolled in a prospective trial for the treatment of breast cancer which included 350 patients, the probability of developing t-AML was calculated to be 0.7% from 25-40 months, using the Kaplan-Meier method (95%, confidence interval (95% CI): 0.1-4.5). CONCLUSIONS The combination of mitoxantrone with cyclophosphamide, fluorouracil, and radiation therapy can induce t-AML, as with other topoisomerase II-targeted drugs. Despite a low incidence, the prognosis appears to be poor.

Abstract
The aim of the study was to test whether the addition of three cycles of chemotherapy during standard radiation therapy would improve disease-free survival in patients with stages III and IV oropharynx carcinoma. A total of 226 patients have been entered in a phase III multicentric randomized trial comparing radiotherapy alone (arm A) to radiotherapy with concomitant chemotherapy (arm B). Radiotherapy was identical in the two arms, delivering, with conventional fractionation, 70 Gy in 35 fractions. In arm B patients received simultaneously 3 cycles of a four-day regimen containing carboplatin (70 mg/m2/d) and 5 fluorouracil (600 mg/m2/d) continuous infusion. The two arms were equally balanced regarding to age, gender, stage, performance status, histology, and primary tumor site. Radiotherapy compliance was similar in the two arms regarding to total dose, treatment duration and treatment interruption. Grade 3 and 4 mucositis rate was significantly higher in arm B (67% versus 36%). Skin toxicity was not different. Haematologic toxicity was higher in arm B on neutrophil count and hemoglobin level. Three-year overall actuarial survival and disease-free survival rates were respectively 51% versus 31% and 42% versus 20% for patients treated with combined modality versus radiation alone (p = 0.022 and 0.043). Local and regional control rate has been improved in arm B (66% versus 42%). The statistically significant improvement in overall survival obtained support the use of concomitant chemotherapy as an adjunct to radiotherapy in the management of carcinoma of the oropharynx.

Abstract
BACKGROUND AND PURPOSE The aim of the study was: (1) to confirm the action of pilocarpine hydrochloride (Salagen) against xerostomia: (2) to correlate the response to dose/volume radiotherapy parameters. MATERIALS AND METHODS From June 1995 to February 1996, 156 patients with severe radiation induced xerostomia received pilocarpine hydrochloride orally. IS mg per day with a 5 mg optional increase at S weeks up to a daily dose of 25 mg beyond 9 weeks. RESULTS One hundred and forty five patients are fully evaluable. Treatment compliance was 75%. Thirty eight patients (26%) stopped treatment before week 12 for acute intolerance (sweating, nausea, vomiting) or no response. No severe complication occurred. Ninety ses en patients (67%) reported a significant relief of symptoms of xerostomia at 12 weeks. Within 12 weeks, the size of the subgroup ith normal food intake almost doubled (13-24 patients) while the size of the subgroup with (nearly) impossible solid food ingestion decreased by 38% (47 vs. 29 patients). The impact on quality of life was considered important or very important by 77% of the responders. CONCLUSIONS No difference was found according to dose/volume radiotherapy parameters suggesting that oral pilocarpine hydrochloride: (1) acts primarily by stimulating minor salivary glands: (2) can be of benefit to patients suffering of severe xerostomia regardless of radiotherapy dose/volume parameters: (3) all responders are identified at 12 weeks.

Abstract
BACKGROUND We designed a randomized clinical trial to test whether the addition of three cycles of chemotherapy during standard radiation therapy would improve disease-free survival in patients with stages III and IV (i.e., advanced oropharynx carcinoma). METHODS A total of 226 patients have been entered in a phase III multicenter, randomized trial comparing radiotherapy alone (arm A) with radiotherapy with concomitant chemotherapy (arm B). Radiotherapy was identical in the two arms, delivering, with conventional fractionation, 70 Gy in 35 fractions. In arm B, patients received during the period of radiotherapy three cycles of a 4-day regimen containing carboplatin (70 mg/m(2) per day) and 5-fluorouracil (600 mg/m(2) per day) by continuous infusion. The two arms were equally balanced with regard to age, sex, stage, performance status, histology, and primary tumor site. RESULTS Radiotherapy compliance was similar in the two arms with respect to total dose, treatment duration, and treatment interruption. The rate of grades 3 and 4 mucositis was statistically significantly higher in arm B (71%; 95% confidence interval [CI] = 54%-85%) than in arm A (39%; 95% CI = 29%-56%). Skin toxicity was not different between the two arms. Hematologic toxicity was higher in arm B as measured by neutrophil count and hemoglobin level. Three-year overall actuarial survival and disease-free survival rates were, respectively, 51% (95% CI = 39%-68%) versus 31% (95% CI = 18%-49%) and 42% (95% CI = 30%-57%) versus 20% (95% CI = 10%-33%) for patients treated with combined modality versus radiation therapy alone (P =.02 and.04, respectively). The locoregional control rate was improved in arm B (66%; 95% CI = 51%-78%) versus arm A (42%; 95% CI = 31%-56%). CONCLUSION The statistically significant improvement in overall survival that was obtained supports the use of concomitant chemotherapy as an adjunct to radiotherapy in the management of carcinoma of the oropharynx.
