ABSTRACT
BACKGROUND: Supportive care in cancer (SCC) was further enhanced in the Second National Cancer Act decreed in December 2009. The aim of our study was to assess current SCC efficacy. PATIENTS AND METHODS: The French speaking association for supportive care in cancer (AFSOS) conducted an observational study to evaluate practices, organisations and information given to patients. A specific 32 point questionnaire was sent to 1621 French physicians (MDs) caring for cancer patients. RESULTS: Three different organisations were evaluated: the individual MDs, the transversal team and its particular structure specialised in global patient care specifically developed at comprehensive cancer centres - CCC. During their disease, 68% of patients received SCC, which was more available during the palliative period (90%) than at the diagnosis (44%). Our results found that 71% of cancer departments had a specific interdisciplinary cross-team to provide SCC, particularly in CCC (62%; p=0.01) while 37% had specific inpatient units. A specific organisation dedicated to home care was greater in CCC than in public or private centres (69%, 45%, 20% respectively; p=0.01). Adverse event information was performed more by an oncologist than other specialists (p=0.01). CONCLUSION: Our results suggest that the specific SCC organisation could be a useful management tool to improve supportive care for cancer patients.

BACKGROUND: This multicenter adjuvant phase III trial evaluated the addition of irinotecan to LV5FU2 in colon cancer patients at high risk of relapse. PATIENTS AND METHODS: A total of 400 patients with histologically proven primary colon cancer with postoperative N1 detected by occlusion/perforation or N2 were randomised to: A-LV5FU2 [leucovorin 200 mg/m(2), 2-h infusion, 5-fluorouracil (5-FU) 400 mg/m(2) bolus, 600 mg/m(2) 22-h continuous infusion, days 1 and 2] or B-LV5FU2 + IRI (irinotecan 180 mg/m(2) 90-min infusion day 1 + LV5FU2) fortnightly for 12 cycles. Primary end point was disease-free survival (DFS). RESULTS: Median follow-up was 63 months. Significantly more T4 tumours and 15 or more positive lymph nodes were observed in arm B. 5-FU relative dose intensity (RDI) was >0.80 for 94% and 77% in arms A and B, respectively (P < 0.001). Irinotecan RDI was >0.80 for 70% patients. There were more grades 3 and 4 neutropenia in arm B (4% versus 28%, P < 0.001). The 3-year DFS was 60% [95% confidence interval (CI) 53% to 66%] and 51% (95% CI 44% to 58) in arms A and B, respectively. No difference was observed [hazard ratio (HR) = 1.12, 95% CI 0.85-1.47, P = 0.42] even when adjusted for prognostic factors (adjusted HR = 0.98, 95% CI 0.74-1.31, P = 0.92). The 5-year overall survival (OS) was 67% (95% CI 59% to 73%) and 61% (95% CI 53% to 67%) in arms A and B, respectively. CONCLUSION: Adjuvant LV5FU2 + IRI compared with LV5FU2 alone in patients at high risk of relapse showed no improvement in DFS and OS.

Chemotherapy has a proven palliative role in advanced gastric cancer, significantly improving quality of life and prolonging survival compared with best supportive care alone. Although there is no standard of treatment, 5-fluorouracil (5-FU)/cisplatin doublets and the combination of epirubicin, cisplatin and 5-FU (ECF) have both achieved response rates in the range of 40-50% and median overall survival of 8-10 months. Either could claim the status of a reference regimen. Single-agent irinotecan achieved response rates (RR) of 18% and 23% in phase II studies, and 48% when combined with cisplatin. However, a randomized trial of irinotecan plus cisplatin versus irinotecan plus 5-FU/folinic acid (FA) showed that the latter regimen achieved a higher RR (34% versus 28%) and significantly longer median survival (10.7 versus 6.9 months). Hematological toxicity was lower with the irinotecan/5-FU/FA combination. This regimen has therefore been taken forward into a randomized phase III comparison against a 5-FU/cisplatin doublet. Use of irinotecan-based combinations should also be investigated as an adjuvant treatment (probably in combination with radiotherapy) and in the neoadjuvant setting.

PURPOSE: To assess the efficacy of irinotecan (CPT-11) in the treatment of advanced colorectal cancer in both chemotherapy-naive and pretreated patients. PATIENTS AND METHODS: Two hundred thirteen patients (aged 18 to 75 years) with metastatic colorectal cancer, World Health Organization (WHO) performance status < or = 2, and life expectancy > or = 3 months were treated with CPT-11 350 mg/m2 every 3 weeks. All 178 patients eligible for efficacy analysis had not received more than one prior fluorouracil (5-FU)-based chemotherapy regimen (adjuvant or palliative) and had adequate hematologic, renal, and hepatic function. RESULTS: Primary tumor sites were the colon (71%) and rectum (28%). Sixty-six percent of the patients had > or = two metastatic sites. Ninety-eight percent of the patients had undergone previous surgery, and 77.5% had received prior chemotherapy. Thirty-two of 178 eligible patients achieved on objective response (four complete responses [CRs] and 28 partial responses [PRs]; response rate, 18%; 95% confidence interval, 12.6% to 24.4%), 65 were stable, and 59 progressed. The response rate was 17.7% in the pretreated group and 18.8% in the chemotherapy-naive group. Within the former subgroup, response rates of 16.1% were reported in patients who were progressive on prior 5-FU chemotherapy and 19.1% in patients who were progressive off such treatment. The median duration of objective response (9.1 months) and median time to achievement of a response (9.3 weeks) did not differ between chemotherapy-naive and pretreated patients. The most frequent adverse events were neutropenia, which developed in 80% of the patients, delayed diarrhea (87%), alopecia (88%), fatigue (81%), and nausea/vomiting (77%). All these adverse events were manageable. Severe (WHO grade 3 or 4) neutropenia was only observed in 18% of the cycles, leukopenia in 11%, delayed diarrhea in 11%, and nausea and vomiting in 3%. Development of simultaneous grade 3 or 4 neutropenia and delayed diarrhea during 4% of the cycles was the safety issue of greatest concern. CONCLUSION: CPT-11 has definite activity in the treatment of advanced metastatic colorectal cancer both in chemotherapy-naive and in pretreated patients who experienced disease progression on 5-FU, which suggests a lack of cross-resistance between CPT-11 and 5-FU. Diarrhea and neutropenia, the major toxicities of CPT-11, contribute to the risk to develop febrile neutropenic sepsis.

Carboplatin is an alternative for cisplatin in the treatment of urothelial cancers. A pharmacologically guided phase I study of carboplatin in combination with methotrexate (30 mg/m2) and vinblastine (4 mg/m2) was conducted in ten patients by increment of the area under the plasma concentration versus time curve (AUC) for ultrafilterable carboplatin using the Calvert formula. The maximal tolerated AUC was 5 mg ml-1 min, with neutropenia being the dose-limiting toxicity. There was a significant linear correlation between the percentage of decrease in neutrophil count and the carboplatin AUC. Determination of the glomerular filtration rate by the isotopic method allowed us to adapt the dose of carboplatin given to patients suffering from urothelial cancer, who frequently have impaired renal function. The recommended AUC for phase II study is 4 mg ml-1 min.

Thirteen patients with intra-abdominal malignancies entered a phase I study of fluorouracil (5-FU) given by continuous infusion (96 h) iv and ip, simultaneously, and modulated by high-dose folinic acid-iv. Severe but reversible stomatitis was the only dose-limiting toxicity at a dose of 5-FU of 550 mg/m2/day. Local toxicity (5-FU-induced abdominal pain) was a significant side effect in patients receiving more than 1 cycle. The pharmacokinetic advantage of 5-FU-ip was confirmed in our study (ratio AUC peritoneum/plasma between 160 and 328). The systemic exposure to 5-FU (plasmatic AUC ranging from 73.4 to 173.21 microM) and to AF were found in efficacious ranges. The recommended dose of 5-FU iv and ip is 500 mg/m2/day. This regimen is feasible and may potentially have application for adjuvant chemotherapeutic programs after surgery for colorectal cancer.
