RESUMO

Catheter-related thrombosis (CRT) is a relatively frequent and potentially fatal complication arising in patients with cancer who require a central catheter placement for intravenous treatment. In everyday practice, CRT remains a challenge for management; despite its frequency and its negative clinical impact, few data are available concerning diagnosis and treatment of CRT. In particular, no diagnostic studies or clinical trials have been published that included exclusively patients with cancer and a central venous catheter (CVC). For this reason, many questions regarding optimal management of CRT remain unanswered. Due to the paucity of high-grade evidence regarding CRT in cancer patients, guidelines are derived from upper extremity DVT studies for diagnosis, and from those for lower limb DVT for treatment. This article addresses the issues of diagnosis and management of CRT through a review of the available literature and makes a number of proposals based on the available evidence. In symptomatic patients, venous ultrasound is the most appropriate choice for first-line diagnostic imaging of CRT because it is noninvasive, and its diagnostic performance is high (which is not the case in asymptomatic patients). In the absence of direct comparative clinical trials, we suggest treating patients with CRT with a therapeutic dose of either a LMWH or a direct oral factor Xa inhibitor, with or without a loading dose. These anticoagulants should be given for a total of at least 3 months, including at least 1 month after catheter removal following initiation of therapy.

RESUMO

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.

RESUMO

BACKGROUND: The aim of the RESGEX study was to compare the efficacy and safety of the anti-epidermal growth factor receptor (anti-EGFR) antibody tomuzotuximab against cetuximab both in combination with chemotherapy in patients with recurrent and/or metastatic squamous cell cancer of the head and neck in the first-line treatment. PATIENTS AND METHODS: In this phase II trial 240 patients were equally randomized for six cycles to receive either tomuzotuximab (initial dose 990 mg then 720 mg) weekly and cisplatin 100 mg/m2 and fluorouracil (5-FU; 1000 mg/m2/day, days 1-4) every 3 weeks or cetuximab (400 mg/m2 subsequent 250 mg/m2) weekly with the same chemotherapeutic backbone followed by antibody maintenance treatment. The primary endpoint was progression-free survival. RESULTS: Median progression-free survival was 6.5 months [95% confidence interval (CI) 5.9-7.9 months] in the tomuzotuximab group and 6.2 months (95% CI 5.8-7.3 months) in the cetuximab group (P = 0.86). The median overall survival (OS) estimate was 11.6 months (95% CI 9.5-17.2 months) in the tomuzotuximab group and 13.8 months (95% CI 12.3-16.4 months) in the cetuximab group (P = 0.96). In an exploratory analysis a small subgroup of p16-positive patients had a significantly longer OS compared with p16-negative patients (hazard ratio 1.860, 95% CI 1.09-3.16, P = 0.02). CONCLUSIONS: The glyco-engineered antibody tomuzotuximab failed to demonstrate improved efficacy with a chemotherapeutic backbone in the first-line treatment of recurrent or metastatic head and neck squamous cell carcinoma. It remains a so far unanswered question whether such antibody would partner better with different drugs such as checkpoint inhibitors.

RESUMO

PURPOSE: Our objective was to compare patient's expectations to their experience and to identify factors predictive of patient's perception of long-term LMWH for the treatment of cancer-associated thrombosis (CAT). METHODS: Results from the validated Perception Anticoagulant Treatment Questionnaires (PACTQ) completed before inclusion (PACTQ1 for expectations) and at the end (PACTQ2 for convenience and satisfaction) of the 6-month TROPIQUE study were studied with principal component analysis. Possible predictive factors of improved perception of LMWH treatment were analyzed with the Kruskall-Wallis test. RESULTS: Among 409 included patients treated with LMWH, 269 PACT-Q1 and 139 PACT-Q2 were evaluable for treatment perception. Patients had high expectations (A1-A7 score of 26.7 ± 3.5, max = 35). Treatment cost (A7 = 1.90 ± 1.31) and concern about a mistake in anticoagulation (A5 = 1.93 ± 1.12) had little importance while LMWH treatment was considered easy to use (A4 = 4.20 ± 0.93). Six-month treatment with LMWH was associated with a high rate of convenience (B1-B11, C1-C2 = 55.1 ± 8.38, max = 65) and a high satisfaction score (D1-D7 = 25.1 ± 4.32, max = 35). Patients' confidence in treatment and perception of possible LMWH side effects were moderate while perception of autonomy and independence significantly improved at the end of the study compared to inclusion. PACT-Q2 satisfaction score was low in patients who experienced bleeding (PACT-Q2 24.1 ± 3.3 vs. 25.1 ± 4.3). LMWH twice daily tended to be found less convenient compared than once daily (53.3 ± 7.2 vs. 55.0 ± 8.3). CONCLUSION: CAT patients had a good perception of the 6-month LMWH treatment when comparing expectations and experience. Using a quantitative scale validated in the general population for VTE and subcutaneous injection and including a large number of patients, bleeding complications and LMWH twice daily were associated with a nonsignificant trend towards a worsen perception.

RESUMO

Apart from myeloma, primary prophylaxis of venous thromboembolism (VTE) in ambulatory cancer patients treated with chemotherapy is underused, despite its proven benefit for pancreatic cancer and to a lesser extent for lung cancer. This prophylaxis has been showed to be effective for myeloma, pancreas but in absolute numbers these cancers lead to a few venous thromboembolic events. Up to date, VTE risk scores cannot be used as a discriminatory criterion to select a high-risk population that could really benefit from this prevention. VTE depends in part on oncogenic mutations of tumor cells that result in an imbalance between activation and inhibition pathways that are involved in venous thrombus formation. So, stratification of risk of VTE in cancer patients could be considered from a clinical and molecular point of view and result in a tailored prophylaxis. This "personalized medicine" that is currently used for the anti-tumor treatment of many cancers and hematological malignancies, could lead to a more effective prophylaxis of VTE in cancer patients.

RESUMO

Pancreatic cancer (PC) is a devastating malignancy with an overall 5-year survival of 8% for all stages combined. Most of the PC patients diagnosed have an advanced disease (40%) or metastatic stage (40%), which eliminates surgery as a potentially curative treatment. The disease course is often complicated by venous thromboembolism (VTE) events, which per se account for significant morbidity and mortality, with significantly worsen survival. PC is associated with the highest risk of VTE among all cancer patients. We review the literature data to address the incidence and clinical outcomes of VTE in PC patients. VTE incidence varies from 5 to 41% according to epidemiological studies and is as high as 57% in postmortem series. Since 2013, international clinical practice guidelines recommend primary thromboprophylaxis with a grade 1B level of evidence as an adjuvant therapy in advanced PC. A recent meta-analysis of randomized controlled trials investigating the benefit and risk of low-molecular-weight heparins (LMWH) in ambulatory advanced PC patients under chemotherapy showed that the incidence of VTE was 2.1% in patients treated with LMWH and 11.2% in controls (risk ratio, 0.18; 95% CI, 0.083-0.39; P<0.0001). In conclusion, improved earlier diagnosis and effective management of VTE, a frequent and life-threatening complication in PC, is warranted to improve PC patient outcomes.

RESUMO

BACKGROUND: Anemia is often associated with a lower quality of life and less tolerance to treatments in cancer patients. OBJECTIVE: The aims of this retrospective study were to assess the biological (hemoglobin, Hb) and clinical (ECOG index) impact of ferric carboxymaltose (FCM) and to identify predictive factors of response in cancer patients with iron deficiency. METHODS: We included 133 patients with solid tumors who received at least one dose of FCM in 2015. RESULTS: At baseline, most patients had metastatic cancer (70%), were undergoing chemotherapy (82%), suffered from anemia (90%), and 72% had an ECOG 0-1 index. Mean Hb level was statistically higher at M1 (108.3 g/L ± 13.9), M2 (110.3 g/L ± 16.1), and M3 (111.7 g/L ± 12.6) than M0 (99.2 g/L ± 13.9). Mean ECOG score increased significantly at M1 (1.31 ± 0.80) and M2 (1.31 ± 0.87) compared to M0 (1.13 ± 0.80). Variations of ECOG index between M0 and M1 were independent of levels of Hb and ferritin at inclusion and pretreatment use of transfusion and ESAs. Increase of Hb level was higher in patients with Hb < 100 g/L, ferritinemia < 800 ng/ml, or transfused before inclusion. In multivariate analysis, an ECOG index of 0 was the only predictive factor of an increase of ECOG index and Hb level < 100 g/L and ferritinemia < 800 ng/ml were predictive of an increase in Hb. CONCLUSION: Even though there was no improvement in ECOG index, this study did identify an increase of Hb for patients receiving FCM, indicating its potential benefit in iron-deficient cancer patients.

RESUMO

PURPOSE: Data on long-term treatment with low-molecular-weight heparins (LMWH) in cancer patients treated for venous thromboembolism are scarce. Study objectives were to document the long-term clinical use of LMWH and patient perception in this setting. METHODS: Adult cancer patients receiving antineoplastic treatment or palliative care and LMWH for cancer associated venous thromboembolism (CAT) were eligible to participate in this prospective observational study. Main outcome was adherence to clinical practice guidelines based on recommended LMWH treatment doses for at least 3months in the absence of severe renal insufficiency. Patients' perception of the treatment was assessed in an ancillary study using the Perception Anticoagulant Treatment Questionnaire (PACT-Q). RESULTS: Among 409 included cancer patients aged 65±12.1years, overall adherence to practice guidelines as defined in the protocol was 55.3% (226 patients). However, 98.0% of patients received a prescription for 3months or more and mean LMWH treatment duration for VTE was 6.27±0.15months which meets guidelines recommendations. Main patients' expectations scored on a 1-5 scale were blood clots prevention (mean 3.94±0.75), symptom relief (mean 3.98±1.04) and ease of use (mean 4.22±0.9). LMWH treatment appeared convenient (global score 79.7±17.1 on a 0 to 100 scale) and 69.1% of patients were satisfied or very satisfied. CONCLUSION: Despite incomplete strict adherence to guidelines, treatment duration with LMWH was adequate showing substantial progress in the management of CAT patients. Patients expectations were high while treatment was perceived convenient with a high degree of satisfaction.

RESUMO

BACKGROUND: Recommendations for management of cancer-related venous thromboembolism (VTE) in patients already receiving anticoagulant therapy are based on low-quality evidence. This international registry sought to provide more information on outcomes after a breakthrough VTE in relation to anticoagulation strategies. METHODS: Patients with cancer and VTE despite anticoagulant therapy were reported to the registry. Data on treatments, VTE events, major bleeding, residual thrombosis symptoms and death were collected for the following 3 months. Breakthrough VTE and subsequent recurrences were objectively verified. Outcomes with different treatment strategies were compared with Cox proportional hazards regression. RESULTS: We registered 212 patients with breakthrough VTE. Of those, 59% had adenocarcinoma and 73% had known metastases. At the time of the breakthrough event, 70% were on low-molecular-weight heparin (LMWH) and 27% on a vitamin K antagonist (VKA); 70% had a therapeutic or supratherapeutic dose. After breakthrough the regimen was: unchanged therapeutic dose in 33%, dose increased in 31%, switched to another drug in 24%; and other management in 11%. During the following 3 months 11% had another VTE, 8% had major bleeding and 27% died. Of the survivors, 74% had residual thrombosis symptoms. Additional VTE recurrence was less common with LMWH than with a VKA (hazard ratio [HR], 0.28; 95% confidence interval [CI], 0.11-0.70) but similar with unchanged or increased anticoagulant intensity (HR, 1.09; 95% CI, 0.45-2.63). The bleeding rate did not increase significantly with dose escalation. CONCLUSION: Morbidity and mortality are high after recurrence of cancer-related VTE despite anticoagulation. Further treatment appears to be more effective with LMWH than with a VKA.

RESUMO

UNLABELLED: Cancer is associated with venous thromboembolism in 20% of patients. In such patients, thrombosis is difficult to treat, associated with bleeding, recurrence, and death. Specific treatments for venous thromboembolism in cancer are recommended. Guidelines have been implemented in many countries and international guidelines have been recently developed. We evaluated the adhesion to national French guidelines via a survey of cancer patients treated for venous thromboembolism. METHODS: A national cross-sectional observational study evaluated the adhesion to guidelines in hospitalized patients. Good clinical practice was defined as initial 10-day treatment with injectable molecules followed by long-term treatment with low molecular weight heparin for at least 3 months. Demographic data, cancer type, stage, treatment, risk factors and type of thrombosis, were recorded. RESULTS: Five patients were included in 47 centers. Overall adhesion to guidelines was present in 59% (55-63%) of patients (295/500). During initial treatment, adhesion was high (487/496; 98%) but dropped (296/486; 62%) during the long-term maintenance. In patients with renal insufficiency, only a fourth of them received the adequate treatment. A majority of patients had metastatic disease (64%). Cancer sites were gastro-intestinal (25%), gynecologic (23%), pulmonary (21%), hematological (14%), urologic (10%), or other (8%). Lung and hematological malignancies were significantly associated with the highest and lowest rates of adhesion. CONCLUSION: Adhesion to national guidelines for treatment of venous thromboembolism in cancer is not optimal. Good compliance is observed during initial treatment, but drops after 10 days, underlying the need for further education to achieve a better implementation on a national level.

RESUMO

BACKGROUND: Guidelines addressing the management of venous thromboembolism (VTE) in cancer patients are heterogeneous and their implementation has been suboptimal worldwide. OBJECTIVES: To establish a common international consensus addressing practical, clinically relevant questions in this setting. METHODS: An international consensus working group of experts was set up to develop guidelines according to an evidence-based medicine approach, using the GRADE system. RESULTS: For the initial treatment of established VTE: low-molecular-weight heparin (LMWH) is recommended [1B]; fondaparinux and unfractionated heparin (UFH) can be also used [2D]; thrombolysis may only be considered on a case-by-case basis [Best clinical practice (Guidance)]; vena cava filters (VCF) may be considered if contraindication to anticoagulation or pulmonary embolism recurrence under optimal anticoagulation; periodic reassessment of contraindications to anticoagulation is recommended and anticoagulation should be resumed when safe; VCF are not recommended for primary VTE prophylaxis in cancer patients [Guidance]. For the early maintenance (10 days to 3 months) and long-term (beyond 3 months) treatment of established VTE, LMWH for a minimum of 3 months is preferred over vitamin K antagonists (VKA) [1A]; idraparinux is not recommended [2C]; after 3-6 months, LMWH or VKA continuation should be based on individual evaluation of the benefit-risk ratio, tolerability, patient preference and cancer activity [Guidance]. For the treatment of VTE recurrence in cancer patients under anticoagulation, three options can be considered: (i) switch from VKA to LMWH when treated with VKA; (ii) increase in LMWH dose when treated with LMWH, and (iii) VCF insertion [Guidance]. For the prophylaxis of postoperative VTE in surgical cancer patients, use of LMWH o.d. or low dose of UFH t.i.d. is recommended; pharmacological prophylaxis should be started 12-2 h preoperatively and continued for at least 7-10 days; there are no data allowing conclusion that one type of LMWH is superior to another [1A]; there is no evidence to support fondaparinux as an alternative to LMWH [2C]; use of the highest prophylactic dose of LMWH is recommended [1A]; extended prophylaxis (4 weeks) after major laparotomy may be indicated in cancer patients with a high risk of VTE and low risk of bleeding [2B]; the use of LMWH for VTE prevention in cancer patients undergoing laparoscopic surgery may be recommended as for laparotomy [Guidance]; mechanical methods are not recommended as monotherapy except when pharmacological methods are contraindicated [2C]. For the prophylaxis of VTE in hospitalized medical patients with cancer and reduced mobility, we recommend prophylaxis with LMWH, UFH or fondaparinux [1B]; for children and adults with acute lymphocytic leukemia treated with l-asparaginase, depending on local policy and patient characteristics, prophylaxis may be considered in some patients [Guidance]; in patients receiving chemotherapy, prophylaxis is not recommended routinely [1B]; primary pharmacological prophylaxis of VTE may be indicated in patients with locally advanced or metastatic pancreatic [1B] or lung [2B] cancer treated with chemotherapy and having a low risk of bleeding; in patients treated with thalidomide or lenalidomide combined with steroids and/or chemotherapy, VTE prophylaxis is recommended; in this setting, VKA at low or therapeutic doses, LMWH at prophylactic doses and low-dose aspirin have shown similar effects; however, the efficacy of these regimens remains unclear [2C]. Special situations include brain tumors, severe renal failure (CrCl<30 mL min(-1) ), thrombocytopenia and pregnancy. Guidances are provided in these contexts. CONCLUSIONS: Dissemination and implementation of good clinical practice for the management of VTE, the second cause of death in cancer patients, is a major public health priority.

RESUMO

BACKGROUND: Although long-term indwelling central venous catheters (CVCs) may lead to pulmonary embolism (PE) and loss of the CVC, there is lack of consensus on management of CVC-related thrombosis (CRT) in cancer patients and heterogeneity in clinical practices worldwide. OBJECTIVES: To establish common international Good Clinical Practices Guidelines (GCPG) for the management of CRT in cancer patients. METHODS: An international working group of experts was set up to develop GCPG according to an evidence-based medicine approach, using the GRADE system. RESULTS: For the treatment of established CRT in cancer patients, we found no prospective randomized studies, two non-randomized prospective studies and one retrospective study examining the efficacy and safety of low-molecular-weight heparin (LMWH) plus vitamin K antagonists (VKAs). One retrospective study evaluated the benefit of CVC removal and two small retrospective studies were on thrombolytic drugs. For the treatment of symptomatic CRT, anticoagulant treatment (AC) is recommended for a minimum of 3 months; in this setting, LMWHs are suggested. VKAs can also be used, in the absence of direct comparisons of these two types of anticoagulants in this setting [Guidance]. The CVC can be kept in place if it is functional, well-positioned and non-infected and there is good resolution under close surveillance; whether the CVC is kept or removed, no standard approach in terms of AC duration has been established [Guidance]. For the prophylaxis of CRT in cancer patients, we found six randomized studies investigating the efficacy and safety of VKA vs. placebo or no treatment, one on the efficacy and safety of unfractionnated heparin, six on the value of LMWH, one double-blind randomized and one non randomized study on thrombolytic drugs and six meta-analyses of AC and CVC thromboprophylaxis. Type of catheter (open-ended like the Hickman(®) catheter vs. closed-ended catheter with a valve like the Groshong(®) catheter), its position (above, below or at the junction of the superior vena cava and the right atrium) and method of placement may influence the onset of CRT on the basis of six retrospective trials, four prospective non-randomized trials, three randomized trials and one meta-analysis. In light of these data: use of AC for routine prophylaxis of CRT is not recommended [1A]; a CVC should be inserted on the right side, in the jugular vein, and distal extremity of the CVC should be located at the junction of the superior vena cava and the right atrium [1A]. CONCLUSION: Dissemination and implementation of these international GCPG for the prevention and treatment of CRT in cancer patients at each national level is a major public health priority, needing worldwide collaboration.

RESUMO

Bisphosphonates are indicated for the treatment of bone lesions in patients with solid tumours or multiple myeloma. Bisphosphonates have proven their effectiveness in reducing the number of bone complications (hypercalcemia, pain, disease-related fractures, spinal cord compression) and delaying their occurrence in patients with bone tumours; they have also been shown to reduce the need for bone surgery and palliative or pain-relieving radiotherapy in these patients. International recommendations for the treatment of bone lesions related to malignant solid tumours and multiple myeloma have been established. We have elaborated clinical practice guidelines on the use of bisphosphonates to assist treatment decision-making in bone oncology. The guide contains decision trees and tables with information to guide pre-treatment evaluation and patient follow-up, as well as indications and conditions of use of bisphosphonates. In 2007, the regional cancer network of Rhône-Alpes, ONCORA, formed a working group (GIP ONCORA) to elaborate the guideline. The final version was then discussed and adopted at a plenary session in July 2009, during a collaborative workshop on supportive care recommendations organized by ONCORA and the regional cancer network of Lorraine.

RESUMO

Systemic amyloidosis usually does not spare the digestive tract but its involvement is rarely symptomatic. The clinical manifestations are not specific. We report a 64-year-old patient, presenting with a weight loss related to an AL amyloidosis. The amyloidosis was apparently limited to the digestive tract. We discuss the various presentations of the digestive amyloidosis and we insist on the seriousness of this localization.

RESUMO

PURPOSE: Granulomatous interstitial nephritis (GIN) are identified in 0.5 to 1,3% of all renal biopsies. Renal outcome and treatment modalities are not clearly established in the literature. METHODS: We retrospectively analyzed a case series of 44 GIN identified among all renal biopsies performed between 1984 and 2005 in the Rhône-Alpes area. RESULTS: The study population included 25 men and 19 women with a mean age of 56 years, and mean diagnostic delay was 11 months. Renal function was severely impaired (mean creatinine clearance 24mL/min). Proteinuria was observed in 77% (mean value 0,9 g/24h) of the patients and associated with microscopic hematuria and leukocyturia in 30% and 25%, respectively. The most common diagnosis was sarcoidosis (25%, n = 11), followed by drug-induced GIN (9%, n = 4), tuberculosis (6,8%, n=3), hemopathy-related paraneoplastic GIN (6,8%, n = 3), HIV infection (n = 1) and chronic renal allograft rejection (n = 1). In other patients, no aetiology was found (48%, n = 21). Severity of renal failure justified hemodialysis in 34% (n = 15) of the patients. Three patients underwent renal transplantation. Nonetheless, renal outcome was generally favorable: renal function improved in 41% (n = 18) and stabilized in 34% (n = 15) of patients. CONCLUSIONS: Sarcoidosis, drug-induced and infections represent the main causes of GIN. Histologic features are not specific enough to determine the aetiology. Corticosteroids is the gold standard in sarcoidosis, drug-induced, and idiopathic GIN. Treatment is etiologic in the other cases.

RESUMO

BACKGROUND: In view of the lack of recommendations on central venous catheter (CVC)-associated thrombosis in cancer patients, we established guidelines according to the well-standardized Standards, Options and Recommendations methodology. MATERIAL AND METHODS: A literature review (1990-2007) on CVC-associated thrombosis was carried out. The guidelines were developed on the basis of the corresponding levels of evidence derived from analysis of the 36 of 175 publications selected. They were then peer reviewed by 65 independent experts. RESULTS: For the prevention of CVC-associated thrombosis, the distal tip of the CVC should be placed at the junction between the superior cava vein and right atrium; anticoagulants are not recommended. Treatment of CVC-associated thrombosis should be based on the prolonged use of low-molecular weight heparins. Maintenance of the catheter is justified if it is mandatory, functional, in the right position, and not infected, with a favorable clinical evolution under close monitoring; anticoagulant treatment should then be continued as long as the catheter is present. CONCLUSIONS: Several rigorous studies do not support the use of anticoagulants for the prevention of CVC-associated thrombosis. Treatment of CVC-associated thrombosis relies on the same principles as those applied in the treatment of established thrombosis in cancer patients.

RESUMO

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

RESUMO

Bleomycin is a cytotoxic agent used in the treatment of various neoplasias. Its cutaneous adverse effects are diverse. Some of them are rare but specific. We report the case of a 40-year-old man presenting with a non-seminomatous testicular germ cell tumour who developed a flagellate erythema related to a bleomycin administration. Clinical features, histopathology and disease course are presented. This side effect is apparently neither related to the dose nor to the mode of administration of bleomycin. The etiopathogenic mechanism remains unknown.

RESUMO

Increased incidence of cancers and the development of totally implanted venous access devices that contain their own port to deliver chemotherapy will lead to a greater than before numbers of central venous catheter-related thrombosis (CVCT). Medical consequences include catheter dysfunction and pulmonary embolism. Vessel injury caused by the procedure of CVC insertion is the most important risk factor for development of CVCT. This event could cause the formation of a fresh thrombus, which is reversible in the large majority of patients. In some cases, thrombus formation is not related to catheter insertion. The incidence of CVC-related DVT assessed by venography has been reported to vary from 30 to 60% but catheter-related DVT in adult patients is symptomatic in only 5% of cases. The majority of patients with CVC-related DVT is asymptomatic or has nonspecific symptoms: arm or neck swelling or pain, distal paresthesias, headache, congestion of subcutaneous collateral veins. In the case of clinical suspicion of CVC-related deep venous thrombosis (DVT), compressive ultrasonography (US), especially with doppler and color imaging, currently is first used to confirm the diagnosis. Consequently, contrast venography is reserved for clinical trials and difficult diagnostic situations. There is no consensus on the optimal management of patients with CVC-related DVT. Treatment of CVC-related VTE requires a five- to seven-day course of adjusted-dose unfractionated heparin or low molecular weight heparin (LMWH) followed by oral anticoagulants. Long-term LMWH that has been shown to be more effective than oral anticoagulant in cancer patients with lower limb DVT, could be used in these patients. The efficacy and safety of pharmacologic prophylaxis for CVC related thrombosis is not established and the last recommendations suggest that clinicians not routinely use prophylaxis to try to prevent thrombosis related to long-term indwelling CVCs in cancer patients. Additional studies performed in high risk populations with appropriate dosage and timing will help to define which patients could benefit from prophylaxis.
