[French recommendations on control measures to reduce the infectious risk in immunocompromised patients]. / Quelles mesures pour maîtriser le risque infectieux chez les patients immunodéprimés ? Recommandations formalisées d'experts.

The increase use of immunosuppressive treatments in patients with solid cancer and/or inflammatory diseases requires revisiting our practices for the prevention of infectious risk in the care setting. A review of the literature by a multidisciplinary working group at the beginning of 2014 wished to answer the following 4 questions to improve healthcare immunocompromised patients: (I) How can we define immunocompromised patients with high, intermediate and low infectious risk, (II) which air treatment should be recommended for this specific population? (III) What additional precautions should be recommended for immunocompromised patients at risk for infection? (IV) Which global environmental control should be recommended? Based on data from the literature and using the GRADE method, we propose 15 recommendations that could help to reduce the risk of infection in these exposed populations.

Phase II randomised trial of raltitrexed-oxaliplatin vs raltitrexed-irinotecan as first-line treatment in advanced colorectal cancer.

The purpose of this phase II randomised trial was to determine which of two schemes, raltitrexed-irinotecan or raltitrexed-oxaliplatin, offered better activity and less toxicity in patients with advanced colorectal cancer (CRC). A total of 94 patients with previously untreated metastatic CRC were included and randomised to receive raltitrexed 3 mg m(-2) followed by oxaliplatin 130 mg m(-2) on day 1 (arm A), or CPT-11 350 mg m(-2) followed by raltitrexed 3 mg m(-2) (arm B). In both arms treatment was repeated every 3 weeks. Intent-to-treat (ITT) analysis showed an overall response rate of 46% (95% CI, 29.5-57.7%) for arm A, and 34% (95% CI, 19.8-48.4%) for arm B. Median time to progression was 8.2 months for arm A and 8.8 months for arm B. After a median follow-up of 14 months, 69% of patients included in arm A were still alive, compared to 59% of those included in arm B. Overall, 31 patients (65%) experienced some episode of toxicity in arm A and 32 patients (70%) in arm B, usually grade 1-2. The most common toxicity was hepatic, with 29 patients (60%) in arm A and 24 patients (62%) in arm B, and was grade 3-4 in four (8%) and four (9%) patients, respectively. In all, 14 patients (29%) from arm A and 24 patients (52%) from arm B had some grade of diarrhoea (P<0.03). Neurologic toxicity was observed in 31 patients (64%) in arm A, and was grade 3-4 in five patients (10%), while a cholinergic syndrome was detected in nine patients (19%) in arm B. There were no differences in haematologic toxicity. One toxic death (2%) occurred in arm A and three (6.5%) in arm B. In conclusion, both schemes have high efficacy as first-line treatment in metastatic CRC and their total toxicity levels are similar. Regimens with raltitrexed seem a reasonable alternative to fluoropyrimidines.

Phase II study of a fixed dose-rate infusion of gemcitabine associated with docetaxel in advanced non-small-cell lung carcinoma.

PURPOSE: To evaluate the efficacy and toxicity profile of the combination of docetaxel and prolonged gemcitabine infusion in front-line chemonaive patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: A total of 50 chemonaive patients diagnosed with advanced NSCLC according to the AJCC/TNM classification system were included in the present study. Treatment consisted of 1000 mg/m(2) gemcitabine given as a 100-min continuous infusion (10 mg/m(2) per min) on days 1 and 8 of each course and 75 mg/m(2) docetaxel as a 60-min infusion on day 8, repeating each course every 21 days. RESULTS: The ECOG performance status of the patients were as follows: 0 (10%), 1 (60%), and 2 (30%). All patients had two-dimensionally measurable disease. Their median age was 63 years (range 41-75 years). Of the 50 patients, 28 (56%) had squamous cell carcinoma, 14 adenocarcinoma (28%), and 8 (16%) large-cell carcinoma, and 40% and 60% of patients presented with stage IIIB and IV disease, respectively. Of those with stage IV disease, 33% had more than one metastatic site. A total of 220 courses were administered with a median of five courses per patient. Of 46 patients assessed for response, 12 (26%) had a partial remission (95% CI 13-39%). In 19 patients (41%) the disease remained stable, while disease progression was observed in 15 (33%). The median time to disease progression was 4 months, and median survival time was 7 months. At 1 year, 25% of patients remained alive, and the main grade 3/4 toxicity (according to the WHO scale) consisted of neutropenia ( n=6, 12%), asthenia ( n=4, 8%), peripheral edema ( n=3, 6%), dyspnea ( n=3, 6%), and diarrhea ( n=2, 4%). CONCLUSIONS: Prolonged gemcitabine infusion combined with docetaxel is well tolerated and its efficacy is similar to that of other chemotherapeutic schemes used for NSCLC treatment. However, the prolonged infusion of gemcitabine did not appear to result in any improvement in outcome or toxicity versus the standard dose rate.

Docetaxel and high-dose epirubicin as neoadjuvant chemotherapy in locally advanced breast cancer.

PURPOSE: Epirubicin and docetaxel are two of the most active drugs against breast carcinoma. As the achievement of a pathological complete response (pCR) is important for survival of patients with locally advanced disease, we used both drugs as neoadjuvant chemotherapy. PATIENTS AND METHODS: Women with locally advanced or inflammatory breast cancer received epirubicin 120 mg/m2 followed by docetaxel 75 mg/m2, both on day 1, every 21 days for four cycles. Lenograstim was administered for 10 days in all cycles. RESULTS: Of 51 patients included, 50 received a total of 188 cycles, with a median of 4 per patient. The median age was 47 years, tumour stage was IIIA in 14 patients and IIIB in 36. Oestrogen receptors were positive in 65% of tumours. There were 10 clinical complete responses (20%) and 29 partial responses (58%). Surgery consisted of mastectomy in 40 patients and tumorectomy in 6. After surgery, 9 pCR were recorded (18%). One patient progressed and died soon after the end of chemotherapy. After a median follow-up of 22 months, the median disease-free survival was 33.7 months. Grade 3/4 neutropenia was observed in 32% of patients, anaemia in 6%, and thrombocytopenia in 4%. Five patients had febrile neutropenia. There were no toxic deaths or grade 4 nonhaematological toxicities. CONCLUSIONS: Docetaxel plus high-dose epirubicin showed promising activity in patients with locally advanced and inflammatory breast cancer, at the cost of moderate toxicity.

Doxorubicin in combination with fluorouracil and cyclophosphamide (i.v. FAC regimen, day 1, 21) versus methotrexate in combination with fluorouracil and cyclophosphamide (i.v. CMF regimen, day 1, 21) as adjuvant chemotherapy for operable breast cancer: a study by the GEICAM group.

BACKGROUND: The purpose of this study was to determine the relative efficacy of doxorubicin versus methotrexate in combination with intravenous cyclophosphamide and 5-fluorouracil (FAC versus CMF) as adjuvant chemotherapy for operable breast cancer. PATIENTS AND METHODS: Over a 4-year period, 985 women undergoing curative surgery for breast cancer (T1-3 N0-2 M0, stage I-IIIA, UICC) from nine hospitals were stratified with respect to axillary node involvement (node positive versus node negative) and randomized to receive either FAC (500/50/500/m(2)) every 3 weeks for six cycles or CMF (600/60/600/m(2)) every 3 weeks for six cycles. RESULTS: The relative dose intensities of FAC and CMF were 87% and 85% of planned doses, respectively. Unadjusted data indicated a non-significant trend towards better results with FAC. In the prospectively formed subset of node-negative patients, disease-free survival and overall survival were statistically superior in the FAC treatment arm (P = 0.041 and 0.034, respectively), but this advantage was not seen in the subset of node-positive patients, probably because of a difference in the percentage of patients with four or more positive nodes. Adjusting data for size of treatment effect and potential interactions (number of positive nodes, tumor size, treatment center), the overall relative risk (RR) of disease recurrence and death were significantly lower with FAC treatment (RR 1.2, P = 0.03, and RR 1.3, P = 0.05, respectively). This result was mainly due to the difference observed in the node-negative patient population. Toxicity was mild: FAC induced more alopecia, emesis, mucositis and cardiotoxicity; this last was of clinical concern, but was infrequent and manageable. CMF induced more conjunctivitis and weight gain. There were no toxic deaths. CONCLUSIONS: Doxorubicin in combination with day 1 i.v. cyclophosphamide and 5-fluorouracil is superior to methotrexate in combination with day 1 i.v. cyclophosphamide and 5-fluorouracil as adjuvant chemotherapy for operable breast cancer. A treatment effect is particularly evident in the node-negative patients. Although the clinical toxicity of FAC is greater than that of CMF, the levels were manageable and clinically acceptable.

Sequential therapy in advanced non-small-cell lung cancer with weekly paclitaxel followed by cisplatin-gemcitabine-vinorelbine. A phase II study.

OBJECTIVES: New effective therapies are needed to improve the outcome of patients with advanced non-small-cell lung cancer (NSCLC). The aim of this study was to assess the response rate and survival obtained with a sequential regimen of chemotherapy. PATIENTS AND METHODS: Patients with newly diagnosed stage IIIb-IV NSCLC were included. They all had measurable disease and a good performance status (0-2 in the Eastern Cooperative Oncology Group scale). Chemotherapy consisted of weekly paclitaxel 150 mg/m2 x 6, followed two weeks later by cisplatin 100 mg/m2 on day 1, gemcitabine 1,000 mg/m2 on days 1 and 14, and vinorelbine 25 mg/m2 on days 1 and 14 (CGV). CGV was administered every 28 days for a maximum of six courses. RESULTS: Fifty-two patients were included, 19 (37%) with stage IIIb and 33 (63%) with stage IV disease. After therapy with weekly paclitaxel. 29 partial responses were obtained (56%, 95% confidence interval (95% CI): 38%-67%), whereas 15 patients had stable disease (29%) and eight had a progression (15%). After CGV, there were four complete remissions (8%) and 24 partial responses (46%), for an overall response rate of 54% (95% CI: 37%-65%). Eight patients had stable disease (15%) and 16 had a progression (31%). No patient progressing after paclitaxel responded to CGV, whereas 5 out of 15 patients with stable disease reached a partial response with CGV (33%). On the contrary, 5 out of 29 patients with a partial response to paclitaxel progressed after CGV (17%). Median survival has not been reached after a median follow-up of 14 months. Median time to progression was nine months. Fifty-six percent of patients remain alive at one year. Two hundred eighty-nine courses of paclitaxel and 170 of CGV were given, with a median of 5.5 and 3.4 per patient, respectively (ranges 2-6 and 0-6. respectively). WHO grade 3-4 toxicities for paclitaxel were: neutropenia in two patients (4/) and peripheral neuropathy in five (10%). Two patients had allergic reactions requiring paclitaxel withdrawal, whereas four (8%) had hyperglycemia >250 mg/ml. Grade 3-4 toxicities for CGV were: neutropenia in ten patients (20%), peripheral neuropathy in six (12%), anemia in four (8%), nausea/vomiting in five (10%). thrombocytopenia in two (4%), and fatigue in four (8%). CONCLUSION: Our results suggest that sequential chemotherapy with weekly paclitaxel followed by CGV is highly active in patients with advanced NSCLC and has an acceptable toxicity. This schedule deserves further evaluation in a phase III study.

Phase II study of ifosfamide plus vinorelbine in metastatic breast cancer patients previously treated with combination chemotherapy.

Forty-six patients were included in a phase II study to evaluate the response rate and toxicity of a combination of ifosfamide and vinorelbine in metastatic breast cancer patients previously treated with one or more regimens of chemotherapy. Treatment consisted of ifosfamide 1.6 g/m(2) IV days 1-3 (with mesna) and vinorelbine 25 mg/m(2) IV days 1 and 8, every 3 weeks up to 6 cycles. The median age was 55 years (range 40-76), the World Health Organization (WHO) performance status was 0-1 in 93% of the patients and 2 in the remaining 7%. In all, 43% had received two or more previous lines of chemotherapy, and 91% had been treated with anthracyclines. Forty-four patients were evaluable for response, and all patients for toxicity. The overall response rate was 36.4% [95% confidence interval (CI) 22.4-52.2]. Stabilization was observed in 20.4% and progression in 43.2%. The median time to progression was 25 weeks (95% CI 14-36). Median relative dose intensity (=actual received dose intensity/planned dose intensity) was 0.99 for ifosfamide and 0. 80 for vinorelbine. The main toxicity was hematological, with 63% of the patients experiencing grade 3-4 neutropenia. With a moderate toxicity, this is an active regimen that may be taken into consideration in pretreated metastatic breast cancer patients when further chemotherapy is indicated.

A randomized phase II trial of 5-fluorouracil, with or without human interferon-beta, for advanced colorectal cancer.

This study compared the efficacy and safety of 5-fluorouracil (5-FU) monotherapy to that of 5-FU combined with natural human interferon-beta (IFN-beta) in patients with unresectable, advanced colorectal carcinoma. Forty-nine chemotherapy-naive patients were randomized to 5-FU alone or to the combination. All patients received 750 mg m(-2) day(-1) 5-FU for 5 days by continuous intravenous (i.v.) infusion, followed after day 15 by a weekly i.v. bolus of 750 mg m(-2). IFN-beta was injected intramuscularly three times weekly at 9 M IU. Treatment continued for 52 weeks, or until disease progression or intolerable toxicity. Clinical endpoints were tumor response, time to progression, survival and toxicity. The addition of IFN-3 to 5-FU significantly improved response rate (33.3% vs 4.5% for evaluable patients; P = 0.021), time to progression (median 7.2 vs 4.2 months; P = 0.0435), and survival time (median 15.9 vs 7.2 months; P = 0.038) without significantly increasing toxicity compared to 5-FU alone. Cumulative 5-FU dose was higher with combined therapy (P < 0.001): more patients receiving monotherapy discontinued treatment because of disease progression. Fever was more frequent with combined therapy (P = 0.008); there were no other differences in toxicity. The only grade IV toxicity observed was neutropenia (two patients per group). A randomized phase III trial has been initiated to confirm the synergy between 5-FU and IFN-beta.

Central venous brachial catheter (P.A.S. Port TM) and catheter scanning system (Cath-Finder TM).

To assess the effectiveness and safety of an implanted portal with a central venous brachial implanted catheter, P.A.S. Port TM(P-P), and the accuracy of its Cath Finder TM tracking system (C-F), (Pharmacia Deltec) vs. radiology, a phase II multicentric study was designed. The catheter was implanted in 53 oncologic patients treated with chemotherapy and the performance of the catheter was evaluated for 3 months. No problems arose during the implantation in 77% of the cases and in all cases radiologic location of the catheter tip coincided with the C-F. We can conclude that P-P is easy to implant and to maintain in the arm and that it is well tolerated by the patients. C-F is an accurate and reliable system for locating the catheter tip. The use of both systems is an attractive alternative to the standard ones.

Treatment of advanced colorectal cancer with recombinant interferon alpha and fluorouracil: activity in liver metastasis.

A cohort of 35 patients with advanced colorectal cancer, not previously exposed to chemotherapy, were included in a phase II study exploring the combination of interferon-alpha, 9 MU subcutaneously three times weekly, and 5-fluorouracil 750 mg/m2/day during 5 consecutive days in continuous intravenous infusion followed with weekly bolus injection of fluorouracil 750 mg/m2. Of 33 cases evaluable for activity; 5 patients achieved partial response and 3 complete response for an overall response rate of 24% (95%; confidence limit 11-42%). Most of the responses were observed in liver metastases, response rate = 30% (95%; CL 13-53%), with little activity observed in other sites; response rate 3% (95%; CL 8-16%), p = .0006. The median time to progression and median overall survival were 16+ (range 1+ to 48+) and 21+ weeks (range 1+ to 52+). All patients were evaluable for analysis of toxicity. Severe mucositis and diarrhea, present in 14 patients were the limiting side effects. Two patients developed progressive renal toxicity and died. Weakness, myalgia, and nonneutropenic fever were observed frequently, one patient developed dementia. This combination is able to induce major responses in patients with advanced colorectal cancer, particularly in liver metastasis. Additional trials evaluating this approach are indicated.
