The prognostic value of respiratory symptoms and performance status in ambulatory cancer patients and unsuspected pulmonary embolism; analysis of an international, prospective, observational cohort study.

BACKGROUND: Optimal risk stratification of unsuspected pulmonary embolism (UPE) in ambulatory cancer patients (ACPs) remains unclear. Existing clinical predictive rules (CPRs) are derived from retrospective databases and have limitations. The UPE registry is a prospective international registry with pre-specified characteristics of ACPs with a recent UPE. The aim of this study was to assess the utility of risk factors captured in the UPE registry in predicting proximate (30-, 90- and 180-day) mortality and how they performed when applied to an existing CPR. OBJECTIVES: To evaluate risk factors for proximate mortality, overall survival, recurrent venous thromboembolism and major bleeding, in the patients enrolled in the UPE registry cohort. METHODS: Data from the 695 ACPs in this registry were subjected to multivariate logistic regression analyses to identify predictors independently associated with proximate mortality and overall survival. The most consistent predictors were applied to the Hull CPR, an existing 5-point prediction rule. RESULTS: The most consistent predictors of mortality were patient-reported respiratory symptoms within 14 days before, and ECOG performance status at the time of UPE. These predictors applied to the Hull-CPR produced a consistent correlation with proximate mortality and overall survival (area under the curve [AUC] = 0.70 [95% CI 0.63, 077], AUC = 0.65 [95% CI 0.60, 070], AUC = 0.64 [95% CI 0.59, 068], and AUC = 0.61, 95% CI 0.57, 0.65, respectively). CONCLUSION: In ACPs with UPE, ECOG performance status logged contemporaneously to the UPE diagnosis and respiratory symptoms prior to UPE diagnosis can stratify mortality risk. When applied to the HULL-CPR these risk predictors confirmed the risk stratification clusters of low-intermediate and high-risk for proximate mortality as seen in the original derivation cohort.

Evaluating prophylactic heparin in ambulatory patients with solid tumours: a systematic review and individual participant data meta-analysis.

BACKGROUND: Study-level meta-analyses provide high-certainty evidence that heparin reduces the risk of symptomatic venous thromboembolism for patients with cancer; however, whether the benefits and harms associated with heparin differ by cancer type is unclear. This individual participant data meta-analysis of randomised controlled trials examines the effect of heparin on survival, venous thromboembolism, and bleeding in patients with cancer in general and by type. METHODS: In this systematic review and meta-analysis we searched MEDLINE, Embase, and The Cochrane Library for randomised controlled trials comparing parenteral anticoagulants with placebo or standard care in ambulatory patients with solid tumours and no indication for anticoagulation published from the inception of each database to January 14, 2017, and updated it on May 14, 2020, without language restrictions. We calculated the effect of parenteral anticoagulant administration on all-cause mortality, venous thromboembolism occurrence, and bleeding related outcomes through multivariable hierarchical models with patient-level variables as fixed effects and a categorical trial variable as a random effect, adjusting for age, cancer type, and metastatic status. Interaction terms were tested to investigate effects in predefined subgroups. This study is registered with PROSPERO, CRD42013003526. FINDINGS: We obtained individual participant data from 14 of 20 eligible randomised controlled trials (8278 [79%] of 10 431 participants; 4139 included in the low-molecular-weight heparin group and 4139 in the control group). Meta-analysis showed an adjusted relative risk (RR) of mortality at 1 year of 0·99 (95% CI 0·93-1·06) and a hazard ratio of 1·01 (95% CI 0·96-1·07). The number of patients with venous thromboembolic events was 158 (4·0%) of 3958 with available data in the low-molecular-weight heparin group compared with 279 (7·1%) of 3957 in the control group. Major bleeding events occurred in 71 (1·7%) of 4139 patients in the control population and 88 (2·1%) in the low-molecular-weight heparin group, and minor bleeding events in 478 (12·1%) of 3945 patients with available data in the control group and 652 (16·6%) of 3937 patients in the low-molecular-weight heparin group. The adjusted RR was 0·58 (95% CI 0·47-0·71) for venous thromboembolism, 1·27 (0·92-1·74) for major bleeding, and 1·34 (1·19-1·51) for minor bleeding. Prespecified subgroup analysis of venous thromboembolism occurrence by cancer type identified the most certain benefit from heparin treatment in patients with lung cancer (RR 0·59 [95% CI 0·42-0·81]), which dominated the overall reduction in venous thromboembolism. Certainty of the evidence for the outcomes ranged from moderate to high. INTERPRETATION: Low-molecular-weight heparin reduces risk of venous thromboembolism without increasing risk of major bleeding compared with placebo or standard care in patients with solid tumours, but it does not improve survival.

Increased dose primary thromboprophylaxis in ambulatory patients with advanced pancreatic ductal adenocarcinoma, a single centre cohort study.

BACKGROUND: Advanced pancreatic ductal adenocarcinoma (aPDAC) patients have a lifetime all type thromboembolic event (ATTE) rate of 25-35%. Efficacy and safety of increased dose primary thromboprophylaxis (IDPTP) with low molecular heparin (LMWH) given for 3 months has been shown in two prospective randomized trials. OBJECTIVES: To report on efficacy -reduction of all type thromboembolic events (ATTE)-, safety -incidence of Major Bleeding (MB)- and compliance in a single-centre cohort of aPDAC patients receiving first line chemotherapy and LMWH-IDPTP. METHODS: From May 2009 to October 2016, 82 patients received IDPTP -LMWH with dalteparin. Schedule: 55 kg and below: 7500 IU, between 55 and 80 kg: 10,000 IU, above 80 kg: 12,500 IU. MB is reported using the International Society of Thrombosis and Haemostasis (ISTH) criteria. ATTE was defined as any arterial or venous event, incidental or clinically symptomatic, including visceral VTE. RESULTS: Mean and median time on dalteparin was 10.2 (95%CI 8.1, 12.4) and 8.0 (95%CI 6.2, 9.7) months respectively. ATTE was observed in 7 (8.5%) of patients, with a median time on IDPTP of 6.2 months (95% CI 10.0, 13.2). MB was seen in 10 (12.2%) patients with a median time on IDPTP of 4.5 months (95% CI 1.6, 7.4). Six major bleeds (60%) were the direct or indirect result of aPDAC. Eighty-one patients had died at the time of data collection with a median overall survival time of 8.7 months (95%CI 6.4, 11.0). Thromboembolism and bleeding were late events. No impact of thromboembolism or bleeding on overall survival was observed. CONCLUSIONS: IDPTP-dalteparin was associated with lower ATTE occurrence rates than expected and comparable major bleeding rates. ATTE and MB were late events, the majority of MB was from direct or indirect result of locally progressing aPDAC. Since these conditions can frequently arise in aPDAC, IDPTP should be regularly reviewed beyond 3 months.

The Khorana score for prediction of venous thromboembolism in cancer patients: An individual patient data meta-analysis.

BACKGROUND: Oncology guidelines suggest using the Khorana score to select ambulatory cancer patients receiving chemotherapy for primary venous thromboembolism (VTE) prevention, but its performance in different cancers remains uncertain. OBJECTIVE: To examine the performance of the Khorana score in assessing 6-month VTE risk, and the efficacy and safety of low-molecular-weight heparin (LMWH) among high-risk Khorana score patients. METHODS: This individual patient data meta-analysis evaluated (ultra)-LMWH in patients with solid cancer using data from seven randomized controlled trials. RESULTS: A total of 3293 patients from the control groups with an available Khorana score had lung (n = 1913; 58%), colorectal (n = 452; 14%), pancreatic (n = 264; 8%), gastric (n = 201; 6%), ovarian (n = 184; 56%), breast (n = 164; 5%), brain (n = 84; 3%), or bladder cancer (n = 31; 1%). The 6-month VTE incidence was 9.8% among high-risk Khorana score patients and 6.4% among low-to-intermediate-risk patients (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.2). The dichotomous Khorana score performed differently in lung cancer patients (OR 1.1; 95% CI, 0.72-1.7) than in the group with other cancer types (OR 3.2; 95% CI, 1.8-5.6; Pinteraction  = .002). Among high-risk patients, LMWH decreased the risk of VTE by 64% compared with controls (OR 0.36; 95% CI, 0.22-0.58), without increasing the risk of major bleeding (OR 1.1; 95% CI, 0.59-2.1). CONCLUSION: The Khorana score was unable to stratify patients with lung cancer based on their VTE risk. Among those with other cancer types, a high-risk score was associated with a three-fold increased risk of VTE compared with a low-to-intermediate risk score. Thromboprophylaxis was effective and safe in patients with a high-risk Khorana score.

Prognostic assessment for patients with cancer and incidental pulmonary embolism.

BACKGROUND: An incidental/unsuspected diagnosis of pulmonary embolism (IPE) in cancer patients is a frequent occurrence. This single-institution analysis of uniformly managed patients investigates short and long-term outcomes and proposes a prognostic risk score, aiming to assist clinical decision-making. METHODS: Data from a prospectively recorded cohort of 234 consecutive cancer patients with IPE were analysed. Multivariate logistic regression and the Cox regression survival methods were used to identify factors with independent association with early (30-day, 3-month, 6-month) mortality and survival. Receiver operator characteristic analysis (ROC) was used to assess appropriate cut-offs for continuous variables and the fitness of prognostic scoring. RESULTS: 30-day, 3-month and 6-month mortality was 3.4% (n = 8), 15% (n = 35) and 31% (n = 72) respectively. Recurrence during anticoagulation occurred in 2.6% (n = 6) and major haemorrhage in 2.1% (n = 5) of the patients. A prognostic score incorporating performance status (0 vs 1-2 vs 3-4) and the presence of new or worsening symptoms, with and without the consideration of the presence of incurable malignancy, correlated with overall survival (p < .001 respectively) as well as early mortality (AUC = .821, p = .004 and AUC = .805, p = 0.006, respectively). CONCLUSION: A simple prognostic score incorporating basic oncologic clinical assessment and self-reported symptomatology could reliably stratify the mortality risk of ambulant cancer patients and IPE.

Advances in managing and preventing thromboembolic disease in cancer patients.

PURPOSE OF REVIEW: To update on new data for low-molecular weight heparins (LMWHs) and the direct oral anticoagulants (DOACs) for the treatment and prevention of cancer-associated thrombosis (CAT), to discuss progress with the risk-adaptive management scores (RAMS) and update on increased dose primary thromboprophylaxis (IDPTP). RECENT FINDINGS: In a pooled meta-analysis of 1132 cancer patients who received DOACs vs. vitamin K analogues (VKAs), recurrence of venous thromboembolism (VTE) was reduced from 6.0% on VKA schedules to 3.9% on DOACs. In a randomized trial of warfarin vs. once daily sc. tinzaparin (175 IU/kg), cumulative 6-month VTE incidence reduced from 10.5 to 7.2% [hazard ratio, 0.65 (95% confidence interval, 0.41-1.03); P = 0.07]. Despite early suggestions that DOACs may have a role in CAT, 3-6 months of LMWH remain the standard for initial treatment of CAT. A prospective comparison of RAMS found the Vienna CATS or the PROTECHT scores superior to the Khorana score but concluded that RAMS did not perform well enough to be used in the clinic. An efficacy scale of LMWHs in pancreatic cancer facilitates IDPTP. Practical implementation of IDPTP was needed to control the 40% VTE incidence of the HALO-109-202 study in metastatic pancreatic cancer. SUMMARY: DOACs have some encouraging data, but LMWHs remain the standard for CAT treatment. RAMS generated to predict VTE occurrence or recurrence are still of unproven significance and IDPTP for advanced pancreatic cancer has tools and guidance for implementation.

The risk of venous thromboembolism associated with peripherally inserted central catheters in ambulant cancer patients.

BACKGROUND: Deep vein thrombosis (DVT) is a common complication of peripherally inserted central catheters (PICCs). PICCs are increasingly utilised in the management of cancer patients, a group which carries both additional risks for vascular thromboembolism as well as for complex morbidity. We analysed a cohort of cancer patients subjected to PICC insertion in a single cancer centre for the incidence of all-type vascular thromboembolism (VTE) and investigated relative risk factors. METHODS: In this clinical audit, the records of patients referred for PICC insertion in our centre in the period between 1/1/2011 and 1/4/2014 were retrospectively reviewed. The primary outcomes investigated were a) PICC-related deep vein thrombosis (PRDVT) and b) distant VTE (lower limb DVT and pulmonary embolism). 4Fr single lumen PICCs were placed in all patients. The Kaplan Meier method was used to study time from PICC insertion to PRDVT/VTE. Survival curves were compared using the log rank method. Logistic and Cox regression analyses were used to assess local, distant and combined endpoints. RESULTS: Four hundred ninety patients were included in the analysis of which 27 (5.5%) developed a PRDVT. Statistically significant risk factors for developing PRDVT in multivariate analysis included more than one attempt for insertion (OR 2.61, 95%CI: 1.12-6.05) and the use of fluoropyrimidine containing chemotherapy (OR 4.27, 95%CI 1.3-14.07). Twenty-six patients developed a distant VTE. Male gender was the only significant risk factor for distant VTE. When all-type VTE were considered together fluoropyrimidine containing chemotherapy (OR 4.54, 95% CI 1.63-12.61), male gender (OR 2.03, 95% CI 1.04-3.93) and white cell count (OR 1.12, 95% CI 1.00-1.26) were statistically significant as risk factors in this analysis. CONCLUSIONS: This is a large study of VTE following PICC insertion in cancer patients which also looks at the rate of distant VTE. The observed PRDVT incidence is comparable with available literature. Fluoropyrimidine containing chemotherapy and more than one attempt for PICC insertion were independent predictors of PICC-associated VTE whilst the former remained an independent predictor of all-type VTE. Anticoagulation did not prevent thrombotic events in this cohort.

Use of heparins in patients with cancer: individual participant data meta-analysis of randomised trials study protocol.

INTRODUCTION: Parenteral anticoagulants may improve outcomes in patients with cancer by reducing risk of venous thromboembolic disease and through a direct antitumour effect. Study-level systematic reviews indicate a reduction in venous thromboembolism and provide moderate confidence that a small survival benefit exists. It remains unclear if any patient subgroups experience potential benefits. METHODS AND ANALYSIS: First, we will perform a comprehensive systematic search of MEDLINE, EMBASE and The Cochrane Library, hand search scientific conference abstracts and check clinical trials registries for randomised control trials of participants with solid cancers who are administered parenteral anticoagulants. We anticipate identifying at least 15 trials, exceeding 9000 participants. Second, we will perform an individual participant data meta-analysis to explore the magnitude of survival benefit and address whether subgroups of patients are more likely to benefit from parenteral anticoagulants. All analyses will follow the intention-to-treat principle. For our primary outcome, mortality, we will use multivariable hierarchical models with patient-level variables as fixed effects and a categorical trial variable as a random effect. We will adjust analysis for important prognostic characteristics. To investigate whether intervention effects vary by predefined subgroups of patients, we will test interaction terms in the statistical model. Furthermore, we will develop a risk-prediction model for venous thromboembolism, with a focus on control patients of randomised trials. ETHICS AND DISSEMINATION: Aside from maintaining participant anonymity, there are no major ethical concerns. This will be the first individual participant data meta-analysis addressing heparin use among patients with cancer and will directly influence recommendations in clinical practice guidelines. Major cancer guideline development organisations will use eventual results to inform their guideline recommendations. Several knowledge users will disseminate results through presentations at clinical rounds as well as national and international conferences. We will prepare an evidence brief and facilitate dialogue to engage policymakers and stakeholders in acting on findings. TRIAL REGISTRATION NUMBER: PROSPERO CRD42013003526.

Developing a complex intervention for the outpatient management of incidentally diagnosed pulmonary embolism in cancer patients.

BACKGROUND: Most patients with pulmonary embolism (PE) spend 5-7 days in hospital even though only 4.5% will develop serious complications during this time. In particular, the group of patients with incidentally diagnosed PE (i-PE) includes many patients with low risk features potentially ideal for outpatient management; however the evidence for their optimal management is lacking hence relative practices may vary considerably. We describe the development process, components, links and function of a nurse-led service for the management of patients with i-PE, developed in accordance to the UK Medical Research Council complex intervention guidance. METHODS: Phase 0 (Theoretical underpinning): The Pulmonary Embolism Severity Index (PESI) was selected for patient risk assessment and the American Society of Clinical Oncology (ASCO) guideline for the management of PE in cancer patients (2007) was selected as quality measure. Historical registry and audit data from our centre regarding i-PE incidence and management for the period between 2006 and 2009 illustrating the then current practices were reviewed. Phase 1 (Modelling): Modelling of the pathway included the following: a) Identification of training needs, planning and implementation of training schemes and development of transferable competencies and training materials. b) Mapping patient pathways and flow and c) Production of key documentation and Standard Operating Procedures for the delivery of the service. RESULTS: Phase 2 (Implementation and testing of the intervention): During the initial 12 months of implementation, remedial action was taken to address identified deficiencies regarding patient referral to the pathway, compliance with treatment protocol, patient follow up, selection challenges from the use of PESI in cancer patients and challenges regarding the "first-pass" identification of i-PE. CONCLUSION: We have developed and piloted a complex intervention to manage cancer patients with incidental PE in an outpatient setting. Adherence to evidence- based care, improvement of communication between professionals and patients, and improved quality of data is demonstrated.

Systemic chemotherapy with pemetrexed and cisplatin for malignant peritoneal mesothelioma: a single institution experience.

BACKGROUND AND AIMS: Primary malignant peritoneal mesothelioma is a rare malignancy with an unfavorable prognosis. Pemetrexed has proven effective in the treatment of malignant mesothelioma, alone or in combination with platinum agents. In the present study, chemo-naïve patients were evaluated for the efficacy and safety of the pemetrexed-cisplatin combination. METHODS: Six patients with diffuse peritoneal mesothelioma were treated with 6 cycles of pemetrexed (500 mg/m2) and cisplatin (75 mg/m2). Chemotherapy was administered on an outpatient basis every 3 weeks. RESULTS: Complete response was observed in 2 patients (33%) and partial response was observed in 3 patients (50%). The estimated median overall survival was 24 months and the estimated median time to disease progression was 9.5 months. The regimen was well tolerated. CONCLUSIONS: Though our data reflect a small sample size, pemetrexed plus cisplatin accomplished a particularly high clinical benefit rate on chemo-naïve patients.

Developments in the systemic treatment of endometrial cancer.

Systemic treatment represents the cornerstone of endometrial cancer management in advanced, relapsed and metastatic disease, which is still characterized by poor prognosis. Progestins remain an effective option for patients with low grade, estrogen and/or progesterone receptor positive disease, with some of them achieving prolonged survival. Platinum compounds, anthracyclines and more recently taxanes have been implemented in combination regimens achieving response rates more than 50% and resulting in overall survival above 1 year in randomized trials. Adjuvant chemotherapy with the same agents may be useful for patients with early stage disease and high-risk features, such as high grade or non-endometrioid histology. Combination of chemotherapeutic agents with radiotherapy remains investigational. Hematologic, cardiac toxicity and neurotoxicity represent the main concern of chemotherapy and increase the risk for treatment-related morbidity and death, especially in pretreated patients bearing substantial co-morbidities. The gradual elucidation of the molecular aspects of endometrial carcinogenesis has led to the development of novel, selective antineoplastic agents, targeting specific molecular pathways and mediators of signal transduction implemented in cell proliferation, survival and angiogenesis. In the current review, we report on the recent advances regarding systemic therapy of endometrial carcinoma with special emphasis on results of large, randomized phase III clinical trials. Biomarkers with potent prognostic significance or predictive value for response to treatment are presented and novel molecular agents showing promising results in early clinical trials are discussed.

Mesenteric desmoid tumor developing on the site of an excised gastrointestinal stromal tumor.

Osteonecrosis of the jaw after a single bisphosphonate infusion in a patient with metastatic renal cancer treated with sunitinib.

BACKGROUND: Osteonecrosis of the jaw (ONJ) is recognised as an important adverse effect of intravenous bisphosphonates. Recent reports have suggested that antiangiogenic agents may promote the development of this condition. CASE REPORT: We report a case of ONJ occurring within days after the first infusion of zoledronic acid in a patient being treated with sunitinib for metastatic renal cancer. No dental procedure contributed to the occurrence of ONJ. The patient had previously experienced oral mucositis caused by sunitinib. ONJ improved with conventional oral hygiene measures, zoledronic acid discontinuation, and hyperbaric oxygen treatment. CONCLUSIONS: Sunitinib-induced mucosal injury and inhibition of angiogenic signalling pathways, also involved in bone repair and remodelling, may have precipitated the phenomenon. A possible synergistic effect may need to be increasingly addressed in the clinical setting since the concomitant use of sunitinib with bisphosphonates is becoming common.

Endometrial cancer: what is new in adjuvant and molecularly targeted therapy?

Endometrial cancer is the most common gynaecological cancer in western countries. Radiotherapy remains the mainstay of postoperative management, but accumulating data show that adjuvant chemotherapy may display promising results after staging surgery. The prognosis of patients with metastatic disease remains disappointing with only one-year survival. Progestins represent an effective option, especially for those patients with low-grade estrogen and/or progesterone receptor positive disease. Chemotherapy using the combination of paclitaxel, doxorubicin, and cisplatin is beneficial for patients with advanced or metastatic disease after staging surgery and potentially for patients with early-stage disease and high-risk factors. Toxicity is a point in question; however, the combination of paclitaxel with carboplatin may diminish these concerns. In women with multiple medical comorbidities, single-agent chemotherapy may be better tolerated with acceptable results. Our increased knowledge of the molecular aspects of endometrial cancer biology has paved the way for clinical research to develop novel targeted antineoplastic agents (everolimus, temsirolimus, gefitinib, erlotinib, cetuximab, trastuzumab, bevacizumab, sorafenib) as more effective and less toxic options. Continued investigation into the molecular pathways of endometrial cancer development and progression will increase our knowledge of this disease leading to the discovery of novel, superior agents.

Prechemotherapy serum levels of CD105, transforming growth factor beta2, and vascular endothelial growth factor are associated with prognosis in patients with advanced epithelial ovarian cancer treated with cytoreductive surgery and platinum-based chemotherapy.

BACKGROUND: Serum CD105 has been associated with angiogenic activity in cancer, and low CD105 expression has been associated with improved prognosis. The present study evaluated the prognostic significance of serum levels of CD105 and related factors in patients with epithelial ovarian cancer (EOC) after cytoreductive surgery and chemotherapy. PATIENTS AND METHODS: Eighty-six patients with stages IIC to IV EOC treated postoperatively with platinum-based chemotherapy were included. The enzyme-linked immunosorbent assay was used to measure prechemotherapy serum levels of CD105, transforming growth factor beta1/2 (TGF-beta1/2), angiopoietin 2, vascular endothelial growth factor, and tumor necrosis factor-alpha. RESULTS: High levels of TGF-beta2 (>8908.86 pg/mL) and CD105 (>4.25 ng/mL) were independently associated with improved overall survival (not reached vs 39 months, P = 0.009 and 75 vs 39 months, P = 0.029, respectively), whereas a high level of TGF-beta2 and a low level of vascular endothelial growth factor (<219.04 pg/mL) were independently associated with improved progression-free survival (49 vs 17 months, P = 0.022 and 57 vs 16 months, P = 0.023, respectively). Among patients with favorable (>4.25 ng/mL) CD105 levels, only patients with low TGF-beta1 levels (<177.1 ng/mL) had superior survival than patients with low CD105 levels. CONCLUSIONS: Our study confirms the prognostic significance of angiogenesis in EOC and supports a biological interaction between CD105 and TGF-beta1. High angiogenic activity may be associated by increased efficacy of postoperative chemotherapy.

Weekly docetaxel with or without gemcitabine as second-line chemotherapy in paclitaxel-pretreated patients with metastatic breast cancer: a randomized phase II study conducted by the Hellenic Co-Operative Oncology Group.

OBJECTIVE: A randomized phase II trial was conducted to test whether the addition of gemcitabine to weekly docetaxel could improve the objective response rate and survival outcomes as second-line chemotherapy in patients with metastatic breast cancer who have failed a paclitaxel-containing regimen. METHODS: Patients were randomized to receive either weekly docetaxel 40 mg/m(2) (group A, n = 34) or the combination of weekly docetaxel 35 mg/m(2) with gemcitabine 600 mg/m(2) (group B, n = 41). Three consecutive weekly infusions followed by a 1-week rest period represented 1 chemotherapy cycle. RESULTS: The objective response rate was 18% and 27.5% in group A and B, respectively (p = 0.413). No statistically significant differences were demonstrated in terms of median overall survival and time to disease progression. The rate and grade 3 and 4 neutropenia were higher in group B (23 vs. 3%). CONCLUSIONS: The weekly administration of docetaxel and gemcitabine did not result in superior clinical outcomes over weekly docetaxel.

Paclitaxel- and platinum-based postoperative chemotherapy for primary fallopian tube carcinoma: a single institution experience.

BACKGROUND: Primary fallopian tube carcinoma (PFTC) is a rare gynecologic malignancy with very few data existing on the activity of the combination of paclitaxel with a platinum analogue as adjuvant chemotherapy. METHODS: We retrospectively analyzed 41 consecutive patients with PFTC who were treated postoperatively with paclitaxel- and platinum-containing chemotherapy regimens. RESULTS: We observed 12 (63.2%) complete and 6 (31.6%) partial responses among 19 patients with measurable disease. The median time to disease progression (TTP) for all patients was 68 months. The median overall survival (OS) for all patients has not been reached yet. The median TTP was 84 months for patients with stage I/II disease and 34 months for patients with advanced disease (p = 0.017). Median OS has not been reached yet for patients with stage I/II PFTC, while it was 63.8 months for patients with stage III/IV disease (p = 0.002). Furthermore, OS has not been reached yet for patients with optimally debulked tumors, while it was 34.1 months for patients with residual disease >2 cm (p < 0.0001). CONCLUSION: Adjuvant platinum- and paclitaxel-based chemotherapy should be regarded as the standard treatment in patients with PFTC. Early stage disease and optimal debulking are associated with improved TTP and OS.

Paclitaxel, topotecan, and carboplatin in metastatic endometrial cancinoma: a Hellenic Co-operative Oncology Group (HeCOG) study.

OBJECTIVE: Taxanes, and platinum compounds represent the chemotherapeutic agents with the greatest activity in metastatic endometrial carcinoma. We administered the combination of paclitaxel, topotecan and carboplatin to patients with metastatic or recurrent carcinoma of the endometrium to evaluate its activity and to define its toxicity. METHODS: Thirty-nine consecutive patients were treated on an outpatient basis with paclitaxel 150 mg/m(2), administered intravenously over a 3-h period and followed by carboplatin at AUC of 5 on day 3, with both agents proceding topotecan that was given at 0.75 mg/m(2)/day on days 1 through 3. The chemotherapy was repeated every 3 weeks with granulocyte colony-stimulating factor (G-CSF) support for a maximum of six courses. RESULTS: Twenty-one (60%) patients achieved objective clinical response (95% CI, 42.2-75.7%) including 4 (11.4%) complete and 17 (48.6%) partial responses. The median times to progression and survival for all patients were 8.9 and 17.7 months, respectively. Grade 3 or 4 thombocytopenia and neutropenia occurred in 5 (13%) and 4 (10%) patients, respectively, but only 2 episodes of neutropenic fever were encountered. Grade 2 or 3 neurotoxicity was observed in 23% of patients. CONCLUSIONS: The combination of paclitaxel, topotecan and carboplatin with G-CSF support appears active with acceptable toxicity in patients with metastatic or recurrent carcinoma of the endometrium.
