RESUMO
PURPOSE AND OBJECTIVES: To report survival and morbidity of a large homogeneous cohort of patients with a locally advanced esophageal or cardia carcinoma and put in evidence predictive factors of locoregional control and survival. PATIENTS AND METHODS: Hundred and two patients were treated at the university hospital of Tours between 1990 and 2010 and received neo-adjuvant chemoradiation therapy with external irradiation (40Gy-44Gy) and two courses of chemotherapy (5-fluoro-uracile and cisplatine). Esophagectomy associated with lymph node dissection was performed about ten weeks after the end of chemoradiation therapy. RESULTS: The median follow-up was 22.4 months [6-185 months]. The overall survival rates at 2 and 5years were 53% and 27%, respectively. The median overall survival was estimated at 27months. The overall 2-year survival between patients "responders" and patients "non-responders" was 67% vs 26%, respectively (P<0.0001). In case of histological response, there was a benefit in terms of overall survival (P<0.0001), locoregional control (P<0.0036) and disease-free survival (P<0.001). Overall survival at 2years was 64% for ypN0 group vs 32% for ypN1 group (P<0.0001). The median survival was estimated at 37months against 15months in the absence of lymph node involvement (P<0.0001). CONCLUSION: Our results in terms of survival, tolerance and morbidity and mortality were comparable to those in the literature. Complete histological response of lymph node was associated with an improvement of local control, disease-free survival and overall survival.

Head and neck cancers are the fifth among the most common cancers in France. Two thirds of cases occur at an advanced stage. For advanced disease, progression-free survival, despite undeniable progress, remains below 50% at three years. The last 20 years have been marked by the necessity to identify situations where less intense surgery and/or radiotherapy and/or chemotherapy is possible without jeopardizing the prognosis, and situations where a therapeutic intensification is necessary and results in a gain in survival while better preserving function with less toxicity. French cooperative groups gathering radiation oncologists (GORTEC), surgeons (GETTEC) and medical oncologists or physicians involved in the management of systemic treatments in head and neck cancers (GERCOR) are now belonging to the INCa-labelled Intergroup ORL to deal with the challenges of head and neck cancers.

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.

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.

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.

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.

PURPOSE: Radiotherapy (RT) and concomitant chemotherapy (CT) is the standard treatment for non resectable esophageal cancer. Usual total radiation dose is 50 Gy. In order to enhance local control rate a Phase II study was initiated to evaluate the feasibility of a combined treatment with an external radiation dose of 60 Gy and three cycles of concomitant CT, using the three main active drugs (CDDP, 5 FU and MMC), followed by a high dose rate (HDR) brachytherapy delivering 10 Gy. METHODS AND MATERIALS: Fifty-three patients, 48 men and 5 women, were entered in this study. Stages were evaluated with CT scan and with endoscopic sonography. Fifteen were Stage IIB, 38 Stage III. Treatment consisted of conventional fractionated RT to a total dose of 60 Gy delivered with 2 Gy per fraction, one fraction per day and five fractions per week. The CT regimen was a combination of Cisplatinum (CDDP) 20 mg/m2 and 5 Fluorouracil (5FU) 600 mg/m2 continuous infusion, from days 1-4 Mitomycin C (MMC) was given at 6 mg/m2 on day 1. Three cycles were administered on days 1, 22, and 43. Brachytherapy was delivered one week after the end of external radiation therapy. RESULTS: Full radiation therapy dose was delivered for 94% of the patients. CT compliance, evaluated on the mean relative dose-intensity was 85% for CDDP, 81% for 5FU and 51% for MMC. Overall grade 3 and 4 WHO toxicity rates were 23% and 7%, respectively. Haematologic toxicity was the most limiting factor. One patient died from treatment toxicity. Local control rate at one year was 74%. Three-year actuarial survival rate was 27%. Distant metastasis was the main cause of treatment failure. Swallowing score was good for 75% of the patients. Stage, performance status and weight loss were prognostic factors. CONCLUSION: This regimen with high dose RT, HDR brachytherapy and concomitant CT is feasible; however, a high level of haematologic toxicity was observed with the CDDP, 5FU and MMC regimen. Despite a poor compliance with CT, treatment results are very encouraging for patients with locally advanced disease.

BACKGROUND: The traditional surgical treatment for operable breast carcinoma larger than 3 cm is mastectomy. To avoid mutilating surgery, the authors administered primary chemotherapy to 158 patients with operable nonmetastatic large breast carcinoma with a TNM classification of T2 greater than 3 cm and T3 with a lymph node status of N0-N1. Conservative treatment was proposed for patients responding to the chemotherapy and whose tumor was reduced to 3 cm or less. The purpose of the study was to evaluate the feasibility and treatment results of this strategy. METHODS: The mean patient age was 50.4 years. Eighty-two patients had T2 carcinomas greater than 3 cm, and 76 had T3 carcinoma. Fifty-four tumors were classified as lymph node status N0, and 104 as N1. Mean tumor size was 5.6 cm. Patients were treated with three courses of the NVCF regimen (mitoxantrone, vindesin, cyclophosphamide, and 5-fluorouracil) or the EVCF regimen, in which mitoxantrone was replaced by epirubicin every 4 weeks, and then administered with a radiosurgical combination. RESULTS: The overall response rate to induction chemotherapy was 60.8% with 20.2% complete tumor regression. Twenty-one percent of the patients experienced grade 3 or 4 chemotherapy toxic effects, which were all acceptable and reversible. Breast-conserving treatment was feasible in 48.7% of patients (77 of 158). Forty-five patients (28.5%) were treated with a radiosurgical combination (tumorectomy plus radiation therapy), whereas 32 (20.2%) were treated with radiotherapy alone (external irradiation and brachytherapy). Other patients were treated with mastectomy. Age, tumor stage, histology, hormonal status, and hormonal receptor rate had no influence on the frequency of the observed regressions. Isolated recurrences occurred in 11 patients, 6 who were treated conservatively and 5 who were treated with mastectomy. Metastatic relapses were observed in 38 patients (14.6% in the chemotherapy responders and 38.7% in the nonresponders) (P < 0.02). Five-year actuarial survival was 73.2% and was significantly higher for responders to the induction treatment. CONCLUSION: These preliminary results suggest that primary chemotherapy and radiosurgical breast-conserving treatment is feasible and is an alternative to mastectomy for patients with large operable breast carcinoma who are responders to the induction treatment. The long term benefit of this strategy must be evaluated in well designed controlled trials.
