Capecitabine, irinotecan, oxaliplatin (CAPIRINOX) and concomitant irradiation in advanced rectal cancer: the Lyon R-02-01 phase I trial.

AIMS: To determine the feasibility of radiotherapy-associated capecitabine, irinotecan and oxaliplatin administration at five dose levels for the treatment of locally advanced rectal cancer, with or without metastasis. PATIENTS AND METHODS: This was a bicentric phase I trial, including patients with locally advanced rectal cancer, with or without metastasis. Chemotherapy comprised capecitabine (1100, 1300 or 1500 mg/m2/day, every day), irinotecan (30, 40 or 50mg/m2, once per week for 6 weeks) with the addition of oxaliplatin (40 mg/m2 at level 4 or 50 mg/m2 at level 5, once per week for 6 weeks). Radiotherapy at 46 Gy plus a boost of 4 Gy was administered concomitantly. RESULTS: Twelve patients received four levels of dose. As a supplement to radiotherapy, the combination of capecitabine and irinotecan at the respective doses of 1500 mg/m2/day and 50 mg/m2/week was feasible and well tolerated. The addition of oxaliplatin to this combination provoked toxicity (grade 3/4 vomiting, diarrhoea) for two-thirds of the patients. CONCLUSION: A treatment associating radiotherapy (46 Gy+4 Gy) with concomitant chemotherapy comprising capecitabine (1500 mg/m2/day, every day) and irinotecan (50 mg/m2/week, for 5 weeks) was feasible and well tolerated. The addition of oxaliplatin to these doses was prohibitory to the continuation of treatment due to unacceptable toxicity.

Long-term cardiac toxicity after adjuvant epirubicin-based chemotherapy in early breast cancer: French Adjuvant Study Group results.

BACKGROUND: The aim of the study was to evaluate and compare incidence and risk factors of left ventricular dysfunction (LVD) in early breast cancer patients receiving (E+) or not (E-) epirubicin-based adjuvant chemotherapy. PATIENTS AND METHODS: Among eight FASG trials, 3577 assessable patients were analyzed retrospectively: 2553 received epirubicin, 662 received hormonotherapy alone and 362 had no systemic treatment. Chemotherapy was FEC regimen in 86% of cases (fluorouracil, epirubicin, cyclophosphamide). Epirubicin cumulative dose was < 300 mg/m2 in 1040 patients, 300-600 in 1155, > or = 600 in 279, followed by radiotherapy in 96% of cases. RESULTS: Twenty delayed LVD occurred: two in E- patients and 18 in E+ patients. In E+ patients, 14 patients normalized their cardiac function or did not require further investigations, one patient was stabilized with specific treatment, two patients worsened their functions and one died of congestive heart failure. The 7-year risk of LVD was 1.36% (95% CI 0.85-1.87) in E+ patients and 0.21% (95%CI: 0.00-0.52) in E- patients (P = 0.004). Two significant risk factors were identified: age > or = 65 years and body mass index > 27 kg/m2. CONCLUSION: After a long-term follow-up, epirubicin-related LVD risk was acceptable (1.36%) with one toxic death (0.04%). In 78% of cases, LVD were transient or well controlled.

Improved disease-free survival with epirubicin-based chemoendocrine adjuvant therapy compared with tamoxifen alone in one to three node-positive, estrogen-receptor-positive, postmenopausal breast cancer patients: results of French Adjuvant Study Group 02 and 07 trials.

BACKGROUND: The purpose was to compare disease-free survival (DFS) between epirubicin-based chemoendocrine therapy and tamoxifen alone in one to three node-positive (N1-3), estrogen-receptor-positive (ER+), postmenopausal early breast cancer (EBC) patients. PATIENTS AND METHODS: We analyzed, retrospectively, 457 patients randomized in FASG 02 and 07 trials who received: tamoxifen alone (30 mg/day, 3 years); or FEC50 (fluorouracil 500 mg/m2, epirubicin 50 mg/m2, cyclophosphamide 500 mg/m2, six cycles every 21 days) plus tamoxifen started concurrently. Radiotherapy was delivered after the third cycle in FASG 02 trial, and after the sixth in FASG 07 trial. RESULTS: The 9-year DFS rates were 72% with tamoxifen and 84% with FEC50-tamoxifen (P = 0.008). The multivariate analysis showed that pathological tumor size >2 cm was an independent prognostic factor (P = 0.002), and treatment effects remained significantly in favor of chemoendocrine therapy (P = 0.0008). The 9-year overall survival rates were 78% and 86%, respectively (P = 0.11). In the multivariate model, there was a trend in favor of chemoendocrine therapy (P = 0.07). CONCLUSION: The addition of FEC50 adjuvant chemotherapy to tamoxifen significantly improves long-term DFS in N1-3, ER+ and postmenopausal women. Chemoendocrine therapy seems to be more effective than tamoxifen in terms of long-term survival.

Secondary leukemia after epirubicin-based adjuvant chemotherapy in operable breast cancer patients: 16 years experience of the French Adjuvant Study Group.

BACKGROUND: The purpose of this study was to evaluate incidence and risk factors of secondary leukemia after adjuvant epirubicin-based chemotherapy in breast cancer patients. PATIENTS AND METHODS: Among eight French Adjuvant Study Group trials, 3653 patients were assessable: 2603 received epirubicin; 682 received hormonotherapy; and 368 had no systemic treatment. Chemotherapy was FEC regimen in 85% of cases (fluorouracil 500 mg/m2, epirubicin 50, 75 or 100 mg/m2, cyclophosphamide 500 mg/m2, three or six cycles). Epirubicin cumulative dose was <300 mg/m2 in 1045 patients; 300-600 mg/m2 in 1187; and > or =600 mg/m2 in 286, followed by radiotherapy in 96% of cases. The median follow-up was 104 months. RESULTS: Eight cases of leukemia occurred in epirubicin-exposed patients and one in non-exposed patients. After 9 years, the risk of developing a leukemia was 0.34% (95% confidence interval 0.11-0.57) in epirubicin-exposed patients. In patients receiving chemotherapy, leukemia subtypes were: AML2 (two), AML3 (one), AML4 (three) and ALL (two). None of the classically recognized risk factors was significantly correlated with the occurrence of a leukemia. CONCLUSION: Irrespective of the dose, the incidence of secondary leukemia after adjuvant epirubicin-based chemotherapy was low. After a long follow-up, the benefit/risk ratio for early breast cancer patients remained in favor of epirubicin-based adjuvant chemotherapy: eight cases (0.31%) occurred, and in some of them, treatment causality could be debatable.

'Parcours de Femme 2001': a French opinion survey on overall disease and everyday life management in 1870 women presenting with gynecological or breast cancer and their caregivers.

PURPOSE: The aim of the survey 'Parcours de Femmes 2001' was to evaluate the overall management and care of women with female cancers and to determine their needs. METHODS: Women with breast or gynecological cancer who had either received at least 3 months of treatment or had completed treatment <1 year before the study were enrolled in this cross-sectional, observational study. RESULTS: From February to November 2001, 2839 questionnaires were distributed; 1870 were returned (66% response rate), mainly by breast cancer patients (87%). While 92% of women reported having received information at diagnosis, 34% of relapsed patients complained of lack of information concerning their disease and treatment. Only 18% of patients were included in the treatment decision process and 66% of women obtained complementary information from the media, patients and care professionals. Fatigue was the most severe problem quoted (78% of cases) and was poorly managed by caregivers due to diagnostic and treatment difficulties. Problems relating to family and to affective and socio-professional life were poorly identified and remained largely unmanaged. CONCLUSIONS: Information given to female cancer patients must be improved in relapsed patients, particularly regarding the adverse effects of treatment. Psychosocial management requires a more holistic approach through new channels, together with the coordination of existing structures.

Treatment of anal canal carcinoma with high dose radiation therapy and concomitant fluorouracil-cisplatinum. Long-term results in 95 patients.

PURPOSE: To evaluate the long-term results of the treatment of anal canal carcinoma (ACC) with a combined concomitant radiochemotherapy (CCRT) treatment using fluorouracil (5 FU) and cisplatinum (CDDP) with a high dose of radiation therapy. PATIENTS AND METHODS: Between 1982 and 1993 a series of 95 patients were treated. Staging showed a majority of advanced squamous ACC, i.e. 6 T1, 47 T2, 28 T3, 14 T4, 53 NO, 32 N1, 6 N2 and 4 N3. Irradiation was done with high dose external beam radiation therapy (EBRT) followed by a boost with 192 Iridium implant. During EBRT all patients received one course of 5 FU continuous infusion (1 g/m2/day, days 1-4) and CDDP (25 mg/m2/day, bolus days 1-4). RESULTS: The median follow-up time was 64 months. At 5 and 8 years the overall survival was 84 and 77%, the cancer specific survival was 90 and 86% and the colostomy-free survival was 71 and 67%, respectively. The stage and the response of the tumor after EBRT were of prognostic significance. Patients with pararectal lymph nodes had an overall 5-year survival of 76% (versus 88% for non-N1). Among 78 patients who preserved their anus, the anal sphincter function was excellent or good in 72 (92%). CONCLUSION: According to these results and recent randomized trials, CCRT appears as the standard treatment of ACC. Radical surgery should be reserved for local recurrence or persisting disease after irradiation. High dose irradiation in a small volume with concomitant 5 FU-CDDP appears to give a high rate of long-term local control and survival. Careful evaluation of pararectal nodes is essential for a good staging of the disease.

Intraoperative radiation therapy combined with limited lymph node resection in gastric cancer: an alternative to extended dissection?

PURPOSE: To describe the results of a series of 63 Western patients presenting with gastric adenocarcinoma and treated with surgery and intraoperative radiation therapy (IORT) over a 8-year period and to discuss the role of IORT when combined with limited lymph node dissection. METHODS AND MATERIALS: From 1986 to 1993, 63 patients with gastric adenocarcinoma have been operated in the department of radiation oncology of the Hospices Civils de Lyon. The stage was: I in 17, II in 11, IIIA in 9, IIIB in 20, and IV in 6. The lymph node dissection was considered to be limited in 56 patients and extended in 7. The IORT dose ranged from 12 to 23 Gy (median: 15). Thirty patients also underwent a postoperative external beam irradiation with a standard dose of 44-46 Gy. RESULTS: The postoperative mortality rate was 4.8%. The 5-year overall survival in the entire series was 47% and was 82, 55, 78, 20, and 0% in Stages I, II, IIIA, IIIB, and IV, respectively. Loco-regional relapse occurred in 15 of 63 patients and metastases in 15 of 63. CONCLUSION: In Western patients treated by gastrectomy for adenocarcinoma of the stomach, IORT combined with limited lymph node dissection may provide overall survival similar to that observed after gastrectomy with extended lymph node dissection but with less postoperative mortality.

Adenocarcinoma of the body and tail of the pancreas: is there room for adjuvant radiotherapy?

AIMS AND BACKGROUND: Adenocarcinoma of the body and tail of the pancreas is a rare malignancy with a poor prognosis. Few long-term survivors have been reported in the literature. The role of adjuvant treatment after curative resection has not yet been assessed. This retrospective study aims to describe the patterns of failure and the survival of 10 patients treated with resection and adjuvant radiotherapy. MATERIALS AND METHODS: From 1982 to June 1994, 10 patients with adenocarcinoma of the body and tail of the pancreas received adjuvant radiotherapy in our department. There were 4 females and 6 males, with a median age of 63 years (range, 45-77). The pT distribution was 2 pT1, 4 pT2, 4 pT3 and for pN it was 7 pN0 and 3 pN1. Four patients had stage I, 3 stage II and 3 stage III disease. All the patients underwent a resection: distal pancreatectomy in 7, partial resection of the body in 1, and total pancreatectomy in 2. Gross residual disease was present in 2 cases. Three patients received intraoperative radiotherapy up to a dose of 12-15 Gy. Postoperative radiotherapy was given in 9 patients with a dose ranging from 40 to 50 Gy (median, 45). One patient who received intraoperative radiotherapy had no postoperative radiotherapy. In 4 patients, chemotherapy with 5-fluorouracil was given during the first week of irradiation. RESULTS: Six patients experienced a local-regional relapse and 3 developed metastases. The median survival was 21 months. The 5-year overall survival was 15%. Eight patients died of progressive disease. One patient who presented with stage I disease was alive and free of disease at 24 months from diagnosis and, interestingly, one with stage III disease was alive at 111 months. No severe treatment-related complications were observed. CONCLUSIONS: As in carcinoma of the head of the pancreas, adjuvant radiotherapy should be considered as an adjuvant treatment of resected adenocarcinoma of the body and tail of the pancreas. Further evaluation is necessary to assess the role of intraoperative radiotherapy.
