Many patients with cancer require palliative care at some stage and the vast majority of people followed in palliative care are cancer patients. Patients with cancer are at high risk of venous thromboembolism (VTE), and this is particularly true during the advanced palliative phase when mobility is limited or absent. Patients with cancer in palliative care are at higher bleeding risk compared to non-cancer patients. Decisions to treat VTE or withhold anticoagulation for these patients have proven to be difficult and depend largely on an individual clinician's judgment. For this reason, we have developed a consensus proposal for appropriate management of cancer-associated thromboembolism (CAT) in patients in palliative care, which is presented in this article. The proposal was informed by the recent scientific literature retrieved through a systematic literature review. In cancer patients in advanced palliative care, the benefit/risk ratio of anticoagulation seems unfavourable with a higher haemorrhagic risk than the benefit associated with prevention of CAT recurrence and, above all, in the absence of any benefit on quality of life. For this reason, we recommend that patients should be prescribed anticoagulants on a case-by-case basis. The choice of whether to treat, and with which type of treatment, should take into account anticipated life expectancy and patient preferences, as well as clinical factors such as the estimated bleeding risk, the type of VTE experienced and the time since the VTE event.

Venous thromboembolism (VTE) is a frequent and potentially fatal complication in patients with cancer. During the initial period after the thromboembolic event, a patient receiving anticoagulant treatment is exposed both to a risk of VTE recurrence and also to an elevated bleeding risk conferred by the treatment. For this reason, the choice of anticoagulant is critical. The choice should take into account patient-related factors (such as functional status, age, body mass index, platelet count and renal function), VTE-related factors (such as severity or site), cancer-related factors (such as activity and progression) and treatment related factors (such as drug-drug interactions), which all potentially influence bleeding risk, and patient preference. These should be evaluated carefully for each patient during a multidisciplinary team meeting. For most patients, apixaban or a low molecular-weight heparin is the most appropriate initial choice for anticoagulant treatment. Such treatment should be offered to all patients with active cancer for at least 6months. The patient and treatment should be re-evaluated regularly, and anticoagulant treatment changed when necessary. Continued anticoagulant treatment beyond 6months is justified if the cancer remains active or if the patient experienced recurrence of VTE in the first 6months. In other cases, the interest of continued anticoagulant treatment may be considered on an individual patient basis in collaboration with oncologists.

Physicians' decision about long-term thromboprophylaxis in cancer outpatients: CAT AXIS, a case vignette study on clinical practice in France.

PURPOSE: Data on long-term venous thromboembolism prophylaxis in cancer outpatients remain scarce. In the absence of clear and consistent treatment guidelines, our objectives were to describe and better understand clinical practice and to identify factors influencing the use of thromboprophylaxis. METHODS: CAT AXIS was a multicentred cross-sectional study based on the completion of physician-profile questionnaires and the assessment of 10 e-mailed credible clinical scenarios of lung, colon and breast cancers by each of participants using the case vignette-validated method. RESULTS: A total of 224 physicians participated allowing the completion and the analysis of 2085 reviewed case vignettes corresponding to 765, 703 and 617 fictive clinical scenarios on lung, colon and breast cancers, respectively. The overall rate of thromboprophylaxis was 680/2085 (32.6%) among participants with a comparable proportion for the three types of cancer. Low-molecular-weight heparin (LMWH) was the most frequently used, by 92.7, 93.8 and 83.9% of participants for lung, colon and breast cancers, respectively; thromboprophylaxis duration of ≥ 3 months was used by 74.4% of participants. Multivariate analyses revealed that the Eastern Cooperative Oncology Group index, metastatic malignancy, chemotherapy and history of thrombosis were significantly associated with the therapeutic decision unlike Khorana score and anaemia. CONCLUSION: In the absence of clear guidance, the use of thromboprophylaxis remains low and rather empiric even though the selection of LMWH by the majority of participants and treatment duration seems appropriate based on available data to date. Specific guidelines with corresponding awareness are required.

Prevention and treatment of cancer-associated thrombosis in France: A national survey among vascular disease and supportive care specialists.

BACKGROUND/AIM: Long-term use of low-molecular-weight heparins (LMWH) for the treatment of cancer-associated thrombosis (CAT) has been well-established. Conversely, the use of thromboprophylaxis in patients with cancer remains controversial in the absence of homogeneous guidelines. Our aim was to assess the awareness of treatment guidelines and the management of patients with CAT in daily clinical practice. METHODS: A national survey based on an open questionnaire developed by a panel of health professionals including specialists in vascular medicine, oncology, supportive care and pharmacy, was proposed on line to 2104 specialists experts in the management of CAT with the objective to collect at least 400 answers. Clinical practice assessment included the treatment of lung adenocarcinoma-associated thrombosis, the use of thromboprophylaxis and factors influencing the management of patients with CAT. RESULTS: A total of 401 questionnaires were completed by specialists of vascular medicine (68%), oncology (12%) and other (20%). LMWH was the preferred option for over 90% of the participants for the treatment of recent overt proximal pulmonary embolism or deep-vein thrombosis. Up to 70% of the participants considered treatment duration for 6 months and more than 12 months in case of active malignancy. Patient management in the setting of incidental VTE and thromboprophylaxis were heterogeneous in the absence of clear guidance while VTE risk scores would be used by only 14% of participants. CONCLUSION: Patients with CAT are properly managed based on clear and consistent guidelines. Patient care is heterogeneous regarding treatment duration beyond 6 months and thromboprophylaxis while VTE risk scores are misused. Identification of referent health care professionals for CAT management and more clear guidelines are required.

[Intrapulmonary bronchogenic cysts]. / Kystes bronchogéniques intrapulmonaires.

INTRODUCTION: Bronchogenic cysts are congenital malformations that are usually located in the mediastinum. Intrapulmonary location is rare. OBSERVATION: Four cases of intrapulmonary bronchogenic cysts are reported in order to discuss their clinical and radiological presentation and their treatment. CONCLUSION: Intrapulmonary bronchogenic cysts diagnostic is often missed. This condition must however be known so as to foresee a resection in order to prevent a potential complication.

[Chamberlain biopsy is not necessary when mature teratoma is evident on imagery]. / Un Chamberlain inutile devant un tératome mature évident à l'imagerie.

INTRODUCTION: Mature teratoma represents 60 % of germinal cells tumours of the mediastinum. Most patients with these tumours are asymptomatic, so the neoplasms are usually discovered by accident during routine chest X-ray examination. They have specific and almost pathognomonic radiological features. However, patients can be symptomatic and may present with chest, back, or shoulder pain; dyspnoea; fever; pleural effusion; cough; and bulging of the chest wall. CASE REPORT: We report the case of a young woman presenting with a giant mediastinal mature teratoma compressing the left lung. The patient was admitted for dyspnoea and non productive cough. The chest X-ray showed a mediastinal mass and a chest computed tomography scan revealed a heterogeneous pluritissular mass lesion of the mediastinum. Complete surgical removal is the treatment of choice for mature cystic teratomas, with optimal results and an acceptable surgical risk. This approach allows confirmation of the diagnosis and is the only way to rule out the presence of malignancy. Surgical biopsy by the Chamberlain method is therefore not strictly necessary. DISCUSSION: When chest X-ray and a computed tomography scan show specific radiological features of teratoma, a complete resection should be undertaken if the patient is fit for surgery. This will confirm the anatomico-pathological diagnosis, exclude the presence of malignant cells and it represents the treatment of choice of mature teratomas.

A risk model for severe anemia to select cancer patients for primary prophylaxis with epoetin alpha: a prospective randomized controlled trial of the ELYPSE study group.

BACKGROUND: Epoetin (EPO) administration reduces the need for transfusion. Identifying patients at high risk of anemia requiring red blood cell (RBC) transfusion is needed. This multicentric phase III trial tested epoetin alpha (EPOalpha) administration according to our risk model on the basis of three clinical parameters: hemoglobin (Hb) <12 g/dl, lymphocytes 1. PATIENTS AND METHODS: Patients >or=18 years with chemotherapy-treated solid or hematologic tumors were randomized to 150 UI/kg/TIW s.c. EPOalpha (arm 1) or no EPOalpha (arm 2) and stratified on Hb level at day 0, lymphocyte count, and PS. The primary end point was transfusion rate; secondary end points included overall survival (OS), safety, and quality of life. RESULTS: From September 2000 to January 2005, 218 patients (median age 64 years, 42.7% males) with principally breast cancer, sarcoma, or lung carcinoma were included. In total, 93% patients had PS >1 and 35% had

A phase II trial of raltitrexed (Tomudex) in advanced pancreatic and biliary carcinoma.

PURPOSE: To evaluate the impact of raltitrexed (Tomudex) on the quality of life in a multicenter, phase II study in advanced pancreatic and biliary carcinomas. PATIENTS AND METHODS: Forty-six patients with advanced, histologically proven pancreatic (n = 37, 80.4%) or biliary (n = 9, 19.6%) carcinoma received 3 mg/m2 raltitrexed intravenously once every 3 weeks. For the quality of life assessments, EORTC QLQ-C30 was used, and the evaluation of the clinical benefit was performed according to the 4 criteria of the clinical benefit response. All patients were assessed for safety, and 41 patients were evaluable for objective response. RESULTS: Patients (63% male/37% female) had a mean age of 61.2 years, 71.7% had a PS of 0-1, 78.3% had metastatic disease, and 63% had at least 2 tumoral sites. A total of 176 cycles were administered with a mean of 4 cycles per patient (range 1-12). Three out of 43 patients evaluable for EORTC QLQ-C30 (7.0%; CI(95%) 1.4-19.0%) had a quality of life improvement. Thirty-two patients fulfilled the 4 criteria required to evaluate the clinical benefit response; 5 were responders (15.6%; CI(95%) 5.3-32.8%); 1 patient was a good responder based on both the EORTC questionnaire and the clinical benefit response. Forty-one patients were assessable for response, 3 responded to treatment (response rate: 6.5 %; CI(95%) 1.3-17.9%). Median survival was 4.6 months (CI(95%) 2.9-8.2 months), the 1-year survival rate was 21.8%. The most common grade 3-4 toxicities were neutropenia (8%), leukopenia (8%), thrombopenia (6%), anemia (6%), liver enzyme elevations (11%), asthenia (9%), vomiting (9%), abdominal pain (7%), and phlebitis (6%). One treatment-related death occurred (neutropenic sepsis). CONCLUSION: Raltitrexed appeared to be generally well tolerated and showed a clinical benefit response and/or quality of life improvement in a limited number of patients.

High-dose sequential epirubicin and cyclophosphamide with peripheral blood stem cell support for advanced breast cancer: results of a phase II study.

The aim of this study was to evaluate the feasibility of a high-dose intensity and high-dose density multicycle epirubicin and cyclophosphamide regimen with peripheral blood stem cells (PBSC) and haematopoietic growth factor (G-CSF) support in advanced breast cancer patients. From August 1994 to September 1999, 56 breast cancer patients (8 stage IIIB and 48 stage IV) received 205 courses of cyclophosphamide 3 g x m(-2) and epirubicin 100 mg x m(-2) every 14 days. G-CSF 5 microg x kg(-1) x day(-1) was administered from day 3 to neutrophil recovery. 4 courses were planned. PBSC were collected after course 1, and reinfused after courses 3 and 4, with > or = 2 x 10(6) CD34+ PBSC x kg(-1) required for each reinfusion. 48 patients (86%) received all 4 planned courses. Early withdrawal was consecutive to infectious complications (n = 4), severe asthenia (n = 3), haemorrhagic cystitis (n = 1). A median number of 10.8 x 10(6) CD34+ PBSC x kg(-1) (range, 3-80) was harvested with 1 or 2 apheresis in 48 patients (94%). Median relative dose intensity was 91.3% (range, 72-102%). Grade 4 neutrophil toxicity was observed in 100% of patients. Febrile neutropenia was observed in 40% of courses (median duration 2 days). Red blood cells and platelets had to be transfused in 54% and 27% of courses, respectively. There were no toxic deaths. Objective response rate was 69% in stage IV patients (31/45 evaluable pts), with a 16% complete response rate. Their median progression-free and overall survivals were 22.5 and 37 months, respectively. This epirubicine-containing high-dose regimen appeared feasible, albeit with high toxicity. Time-related progression parameters exceed commonly reported ones. Controlled studies of upfront sequential high-dose chemotherapy are still needed to evaluate its real benefit.

A case of chronic neutrophilic leukemia with deletion (11)(q23).

We report a case of chronic neutrophilic leukemia (CNL) in a 68-year-old man. Karyotype showed a clonal abnormality, never described before in CNL: 46,XY,del(11)(q23). Southern blot analysis of the MLL gene did not reveal any rearrangement, and reverse transcriptase polymerase chain reaction (RT-PCR) analysis did not show any fusion of BCR-ABL. Treatment with hydroxyurea and cytosine arabisonide was ineffective.

Outpatient treatment with subcutaneous interleukin-2 and interferon alfa administration in combination with fluorouracil in patients with metastatic renal cell carcinoma: results of a sequential nonrandomized phase II study. Subcutaneous Administration Propeukin Program Cooperative Group.

PURPOSE: We report the results of the Subcutaneous Administration Propeukin Program (SCAPP) II trial of an outpatient treatment in renal cell carcinoma using interleukin-2 (IL-2) and interferon alfa-2a (IFN-alpha) administered subcutaneously in combination with fluorouracil (5-FU). The objective of this multicenter trial was to confirm that the combination of IL-2, IFN-alpha, and 5-FU leads to a response rate greater than 20%. PATIENTS AND METHODS: Patients with metastatic renal cell carcinoma were included in this study. During the induction phase of the treatment, which lasted 10 weeks, IL-2 and IFN-alpha were administered subcutaneously three times a week for 8 weeks at doses of 18 MIU and 9 MIU, respectively. During these 8 weeks, every Monday, 5-FU was administered at a dose of 750 mg by intravenous infusion over 30 minutes. After evaluation, responding patients or patients with stable disease (SD) were given maintenance treatment, until disease progression (PD) or the appearance of unacceptable toxicity. Each maintenance cycle consisted of a 2-week treatment followed by a three-week rest period. During treatment, IL-2 and IFN-alpha were administered subcutaneously three times a week at doses of 18 MIU and 9 MIU, respectively. Every Monday, 5-FU was administered at a dose of 750 mg by intravenous infusion over 30 minutes. RESULTS: This trial was closed when the sixth sequential analysis showed the lack of benefit from this combination. At the end of the induction period, of 62 patients, 12 (19%; 95% confidence interval [CI], 10% to 31%) reached an objective response, including one complete response (CR), 16 presented with SD, and 27 showed PD. Twenty-seven patients (43%) developed severe toxicity that required reduction of the planned doses (13 patients), delayed treatment (eight patients), or treatment termination (six patients). Seventeen patients were given maintenance treatment. One- and 2-year survival rates were estimated at 55% and 33%, respectively. The 2-year survival rate was 15% in 11 patients who presented with three poor-prognosis factors and 41% in 51 patients who initially presented with no, one, or two poor-prognosis factors (P = .04). CONCLUSION: As in other recently published studies that used 5-FU, IL-2, and IFN-alpha, the multicenter SCAPP II trial in patients with metastatic renal cell carcinoma generated severe toxicity. This sequential trial failed to confirm the favorable results previously obtained by Atzpodien and Sella with this combination of three drugs. Its efficacy, assessed on the response and survival rates, is near to the results observed in programs that used IL-2 alone given subcutaneously.

[Subcutaneous administration of interleukin-2 in ambulatory treatment of patients with metastatic renal cancer. Three-year results of the SCAPP I program]. / Traitement ambulatoire par interleukine 2 administrée par voie sous-cutanée chez des patients porteurs d'un cancer du rein métastatique. Résultats à 3 ans du programme SCAPP i.

We report a french experience of subcutaneous administration of interleukin-2 in treatment of patients with metastatic renal cell carcinoma. Thirty-nine patients with metastatic renal cell carcinoma were included in the study. During the 10-week induction period, interleukin-2 was administrated subcutaneously 5 days a week for 8 weeks. The weekly dosage were 90 MIU during weeks 1 and 6; 63 MIU during weeks 2 to 4 and 7 to 9. After evaluation, responders and patients with stable disease received maintenance treatment which was discontinued upon the appearance of disease progression or unacceptable toxicity. During the maintenance period, interleukin-2 was administered 5 days a week for 4 weeks followed by a 2-week rest period. The weekly dosages were 90 MIU in week 1 and 63 MIU in weeks 2 to 4. After completion of induction treatment, 7 of 39 evaluable patients (18%) had objective responses with 1 complete response. A diminution of dose or interruption of treatment occurred with 7 patients because severe toxicity. Other systemic side effects in the remaining patients were acceptable. Seventeen patients received maintenance treatment. The median follow-up of all the patients included was 21 months. The 1, 2 and 3 years survivals were 64%, 33% and 22% respectively. This multicentric trial confirms the efficacity of subcutaneously-administered interleukin-2 in patients with metastatic renal cell carcinoma in terms of both response rate and survival. Unfortunately, increasing total doses of administrated interleukin-2 does not seem to increase efficacity according to response rate, but is more toxic.

Subcutaneous recombinant interleukin-2 (rIL-2) in out-patients with metastatic renal cell carcinoma. Results of a multicenter SCAPP1 trial.

BACKGROUND: This multicenter phase II trial was conducted in order to evaluate the efficacy and toxicity of the subcutaneous route of administration of rIL-2 in the treatment of patients with metastatic renal cell carcinoma and to check whether an increased cumulative dose of rIL-2 increases efficacy. PATIENTS AND METHODS: Thirty-nine patients with metastatic renal cell carcinoma were included in this study. During the induction period, rIL-2 was administered subcutaneously 5 days a week for 8 weeks. The weekly dosages were 90 MIU during weeks 1 and 6;63 MIU during weeks 2 to 4 and 7 to 9. After evaluation, responders and patients with stable disease received maintenance treatment which was discontinued upon the appearance of disease progression or unacceptable toxicity. During the maintenance period, rIL-2 was administered 5 days a week for 4 weeks followed by a 2-week rest period. The weekly dosages were 90 MIU in week 1 and 63 MIU in weeks 2 to 4. RESULTS: After completion of induction treatment, 7 of 39 evaluable patients (18%) had objective responses (95% CI: 9% to 37%) with one complete response. Treatment was interrupted or reduced due to toxicity for seven patients: Neuropsychiatric symptoms (3 patients), joint pain (1 patient), major asthenia and anorexia (1 patient), stroke (1 patient), and septicemia (1 patient). Other systemic side effects in the remaining patients were acceptable. Seventeen patients received maintenance treatment. In none of the patients did the response status improve during this maintenance period. The median follow-up of all of the patients included was 19 months. The one- and two-year survivals were 65% and 33%, respectively, ad the median duration of response was 11 months (5 to 16+). CONCLUSIONS: This multicentric study confirms the efficacy of subcutaneously-administered rIL-2 in patients with metastatic renal cell carcinoma in terms of both response rate and survival. The role of a maintenance therapy needs further evaluation.
