Brentuximab-induced peripheral neuropathy: Risk factors and patient experiences.

120 Background: Brentuximab vedotin (BV) is an immunoconjugate used in Hodgkin lymphoma (HL) and other CD30+ lymphomas. The dose-limiting adverse effect is peripheral neuropathy (BIPN). Predictors of BIPN, effect on outcomes, and the biopsychosocial impact are not well defined. Methods: We conducted a single institution, mixed-methods study of lymphoma patients (pts) who received BV between 1/2010 and 5/2016. A retrospective analysis was conducted in all pts; an open-ended survey was given to pts seen in the prior year. A univariate analysis examined the association between BIPN and potential predictors. Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan Meier method. Survey data were analyzed qualitatively via a framework approach. Results: Eighty-nine pts were eligible: 56% were male, 54% had HL, 71% had prior neurotoxic drugs, 93% received single agent BV. The median number of BV doses was 5. Forty-three (48%) pts developed BIPN. It resolved completely in 14 (33%) pts at a median follow-up of 12 mo. The median time to resolution was 13 wks. BV therapy was altered in 21 (24%) pts due to BIPN. There was no difference in PFS (6 vs. 12 mo., p = 0.09) or OS (NR vs. 26 mo., p = 0.11) in pts who had therapy altered due to BIPN. Table 1 lists significant risk factors for BIPN. No additional factors investigated (age, sex, prior neurotoxic agent, underlying neuropathy, diabetes mellitus or BMI) increased risk for BIPN. Fourteen of the 18 (78%) surveyed pts reported BIPN. At a median follow-up of 24 mo., 10 (71%) pts reported ongoing symptoms. BIPN affected quality of life in 50% and work in 20% of pts. Despite significant symptoms from BIPN, all pts were satisfied with their decision to receive BV regardless of disease response. Conclusions: BIPN is a significant adverse event and may fail to resolve in a large subset of pts. Surveyed pts reported that the benefits of BV outweigh the risks. Changes in therapy due to BIPN occur, but this did not affect outcomes in our cohort. Clinicians should be aware of the risk for BIPN and educate pts accordingly. [Table: see text]

We aimed to evaluate the role of pretreatment carcinoembryonic antigen (CEA) and platelet to lymphocyte ratio (PLR) in predicting brain metastasis after radical surgery for lung adenocarcinoma patients. The records of 103 patients with completely resected lung adenocarcinoma between 2013 and 2014 were reviewed. Clinicopathologic characteristics of these patients were assessed in the Cox proportional hazards regression model. Brain metastasis occurred in 12 patients (11.6%). On univariate analysis, N2 stage (P = 0.013), stage III (P = 0.016), increased CEA level (P = 0.006), and higher PLR value (P = 0.020) before treatment were associated with an increased risk of developing brain metastasis. In multivariate model analysis, CEA above 5.2 ng/mL (P = 0.014) and PLR ≥ 120 (P = 0.036) remained as the risk factors for brain metastasis. The combination of CEA and PLR was superior to CEA or PLR alone in predicting brain metastasis according to the receiver operating characteristic (ROC) curve analysis (area under ROC curve, AUC 0.872 versus 0.784 versus 0.704). Pretreatment CEA and PLR are independent and significant risk factors for occurrence of brain metastasis in resected lung adenocarcinoma patients. Combining these two factors may improve the predictability of brain metastasis.

Abstract Background: Despite the advances in the treatment for multiple myeloma (MM) in the past decade, it still remains an incurable haematological disease and the majority of patients still experience relapse. Bortezomib is a novel proteasome inhibitor approved for the treatment of MM patients. Several studies have demonstrated its efficacy as front-line therapy and in relapsed, advanced MM but no data are available as maintenance therapy (MT) in refractory/relapsed MM. Patients and methods: The aim of this study is to evaluate the safety and the efficacy of bortezomib/dexamethasone MT (1.3 mg/mq bortezomib on days 1 and 15; 20 mg dexamethasone on days 1–2 and 15–16 in a 28-day cycle for a total of 6 cycles) in patients with refractory/relapse MM who responded to salvage therapy. Results: From October 2004 until April 2008, 40 MM patients have been enrolled. The characteristics of the patients were as follows: 20 males and 20 females, median age was 70 years (IQR:66–75). Median haemoglobin value was 10.85 (IQR:10.175–12.225) and 7 (18%) patients had a renal failure. Skeletal disease was present in 27 (68%) patients. The median number of prior therapies was 2 (1–4). The salvage therapy included bortezomib as single agent or in combination with steroids and/or thalidomide in 12 patients (30%). Median time from diagnosis to the first dose of MT was 41 months (IQR:26–59). The median number of bortezomib infusion was 8 (1–18). After a median follow up of 13 months (IQR:6–31), 10 patients died for PD and 4 patients for infections. The MT improved the quality of response and converted in 1 CR and 4 VGPR the PR after salvage therapy in 5 patients; moreover, we observed a remarkable decreased of M component in 11 patients. The median time to progression was 23 months (95%CI: 8-not reached) with a progression free-survival at 1 year of 69% (95%CI: 50–82). The overall survival at 1 years was 63% and the cumulative incidence of death due to PD adjusted for competitive risk event was 25% (95%IC:10–41). In a univariate analysis the response rate to MT was not significantly affected by age, sex, number or type of previous therapy and haemoglobin concentration. Non-dose-limiting toxicities included neuropathy grade 1 (12 pts), herpes zoster reactivation (2 pts) and gastrointestinal affections (1 pts). Conclusion: The combination bortezomib/dexamethasone can be safely administered as a maintenance therapy in relapse/refractoy MM. These preliminary data suggest that bortezomib/dexametasone MT can improve remission duration and also quality of response with an acceptable toxicity.

Abstract Abstract 539 Introduction: The addition of rituximab to fludarabine-based regimens in CLL has been shown to produce high response rates with extended remissions. The long-term follow-up of these regimens with respect to progression, survival, and development of secondary malignancies has been limited. Patients and Methods: We report the long-term follow up of the chemoimmunotherapy trial CALGB 9712 (Blood 2003;101:6-14). This trial randomized 104 untreated, symptomatic patients to receive either 6 monthly cycles of fludarabine plus rituximab (FR) followed 2 months later by 4 weekly doses of rituximab (concurrent arm) or 6 monthly cycles of single agent fludarabine followed by rituximab consolidation using 4 weekly doses (sequential arm). With a median follow up of 92 months (range: 60-107), we analyzed the updated CALGB database and flow sheets submitted by treating physicians. Results: The overall response rate (ORR) was 84% (95% CI: 77%-91%), with a 90% ORR in the concurrent group (95% CI: 82%-98%) and a 77% ORR in the sequential group (95% CI: 66%-89%). Complete response (CR) was seen in 38% of patients (95% CI: 30%-45%), and partial response (PR) in 46% (95% CI: 38%-54%). The median OS was 85 months (95% CI: 71-95), with 71% of patients alive at 5 years (95% CI: 61%-79%). The median PFS was 37 months (95% CI: 27-45), with 27% progression-free at 5 years (95% CI: 19%-36%). With long-term follow up, the estimated median OS and PFS for the concurrent group were 84 months (95% CI: 57-100) and 32 months (95% CI: 23-55), respectively; the median OS and PFS for the sequential group were 91 months (95% CI: 71-110) and 40 months (95% CI: 23-50), respectively. Patients with del(17p13.1)/del(11q22.3)(18 patients) and unmutated IgVH(43 patients) continue to have an inferior OS (P=0.01 and P=0.04, respectively) and PFS (P=0.03 and P=0.04, respectively) compared to those without these abnormalities. We next assessed the frequency of therapy-related myeloid neoplasms (t-MN) and other cancers occurring after this chemoimmunotherapy regimen. No patient has developed MDS or AML prior to relapse. One patient (1%) developed t-MDS following relapse and receipt of FCR 41 months after completing trial therapy; t-MDS was diagnosed 9 months later. Richter's transformation was noted in three (3%) of the CALGB 9712 patients with large cell (n=2) or Hodgkin lymphoma (n=1). Second malignancies have included localized basal cell or squamous cell skin cancer in 12 (12%) patients whereas 11 (11%) have developed other epithelial malignancies including 4 GI, 3 lung, 3 melanomas, and 1 prostate cancer. Conclusions: Long-term follow up of patients enrolled on CALGB 9712 demonstrates extended OS and PFS with fludarabine plus rituximab, given either concurrently or sequentially, with an estimated 17%(95% CI: 9%-27%) of responders still in remission 8 years later. Looking at other published data, patients treated with FR administered concurrently or sequentially do not appear to have an increased risk of t-MN or second cancers. These long-term data reaffirm that FR is one of several acceptable frontline treatments for symptomatic patients with CLL. Disclosures: Morrison: Genentech: Speakers Bureau.

Abstract Background Richter's transformation (RT) refers to the development of an aggressive lymphoma in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic leukemia (SLL). Roughly, 2-10 % of patients with CLL develop RT most often as diffuse large B-cell lymphoma (DLBCL) or Hodgkin lymphoma (HL). Aim This study aimed to assess the incidence rate and risk factors for RT for patients with CLL in a nationwide cohort. Furthermore, we want to assess prognostic risk factors for patients with RT. Methods All patients diagnosed with CLL in Denmark between 2008 and 2016 were included in this study. Clinical data was retrieved from the Danish National CLL Registry (DCLLR), whereas all histologically verified DLBCL, HL and/or transformation diagnoses for patients with CLL were retrieved from the Danish National Pathology Registry. Patients were followed from date of CLL diagnosis until date of RT, death or end of follow-up, whichever came first. The time to RT was estimated as cumulative incidence considering death as a competing risk. Stepwise Cox analysis with backward elimination was applied to identify independent risk factors for RT in patients with CLL. Results A total of 3771 CLL patients were identified, and followed for 14165 person-years. With a median follow-up of 4.3 (IQR (2.4;6.6)) years, 120 (3%) CLL patients had a transformation diagnosis, of which 4 patients were excluded due to misdiagnosis. DLBCL accounted for 78/116 (67%) cases, HL for 15/116 (13%) cases and one patient presented with both DLBCL and HL. In the remaining 22/116 (19%) cases the subtype of the transformation was either unspecified or unclassified RT. The median time to RT was 3.4 (IQR (1.8;5.7)) years from CLL diagnosis and the median overall survival (OS) after development of RT was 4.9 (IQR (0.7;8.4)) years. The cumulative incidence of RT, calculated by Aalen-Johansen estimator, at 5 and 8 years post-CLL diagnosis were 3.3% and 7.9% respectively (Figure 1). The annual crude incidence rate of RT was approximately 0.7% per year for all CLL patients. In all, 918 (24%) patients received CLL-related treatment, of whom 59 (6.4%) patients developed RT, resulting in a cumulative incidence of RT of 7% after 5 years and 11% after 8 years. At the time of CLL diagnosis, patients treated for CLL prior to RT diagnosis had a worse median OS (1.49 years) compared to RT patients who were untreated for CLL (6.16 years). In the univariate analysis, RT was significantly associated with male gender, advanced Binet stage (B or C), unmutated IGHV status (CLL-U), elevated beta-2-microglobulin (>3.5 mg/L) and elevated lactate dehydrogenase (>205 U/L). Of cytogenic aberration, deletion 13q (del(13q)) had a protective effect on the risk of RT, whereas deletion 11q (del(11q)) and deletion 17p (del(17p)) increased the risk. In the multivariable model, advanced Binet stage (HR 2.86 (1.82;4.51), p<0.001), del(17p) ((HR 3.74 (2.12;6.61), p<0.001) and CLL-U ((HR 2.30 (1.46;3.63), p<0.001) showed an independent correlation with development of RT. ZAP70 and CD38 were excluded from statistical analyses due to incomplete data and high inter-laboratory variation. Among RT patients, CLL-U, trisomy 12 and del(17p) at CLL diagnosis as well as ECOG Performance Status (PS) (i.e. PS≥1) at time of RT diagnosis correlated with poor OS in univariate analysis. Both del(17p) and PS≥1 were independently associated with an increased risk of death in a multivariable analysis (HR 2.9, (1.1;7.7), p=0.04 and HR 3.0, (1.0;3.1), p=0.05, respectively). Conclusions To the best of our knowledge, we here report the largest study on RT assessing nationwide data of consecutive patients diagnosed with CLL. The incidence of RT in this unselected population was 3.3% after 5 years while the median OS for patients from time of RT was 4.9 years. Advanced Binet stage, del(17p) and CLL-U were significantly and independently associated with an increased risk of RT. Del(17p) at CLL diagnosis and PS≥1 at RT diagnosis were significant predictors for death for patients with RT. For patients diagnosed with RT prior to any CLL treatment, a less severe disease course with a median OS of 6.16 years was demonstrated. Contrary, the median OS for patients receiving prior CLL treatment was 1.49 years. Thus, assessment of different treatment options for patients developing RT based on whether they have received prior CLL treatment or not is warranted. Figure 1. Figure 1.

After elective sigmoidectomy for diverticulitis, patients may experience persistent abdominal symptoms. This study aimed to determine the incidence and characteristics of persistent symptoms (PSs) and their risk factors in patients who had no reported recurrence after elective sigmoidectomy. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included. After retrospective review of medical records, patients were contacted with a questionnaire to inquire about recurrence of diverticulitis and persistent abdominal symptoms since resection. Outcomes examined were prevalence of and risk factors for PSs after elective sigmoidectomy. Of 662 included patients, 346 completed the questionnaire and had no recurrent diverticulitis. PSs were reported by 43.9 per cent of the patients. The mean follow-up was 87 months. Female gender and preoperative diagnosis of irritable bowel syndrome were independent risk factors for PSs (Relative Risk 1.65, P < 0.001 and Relative Risk 1.41, P = 0.014). Previous IVantibiotics treatment was associated with PSs ( P = 0.034) but not with a significant risk factor. As the follow-up interval increased, prevalence of PSs decreased ( P = 0.006). More than 40 per cent of patients experienced persistent abdominal symptoms after sigmoidectomy for diverticulitis. Female patients and those with irritable bowel syndrome were at significantly increased risk.

Background: Atrioventricular reentrant tachycardia is common in children. Catheter ablation is increasingly used as a first-line therapy with a high acute success rate, but recurrence during follow-up remains a concern. The aim of this study was to identify risk factors for recurrence after accessory pathway (AP) ablation. Methods: Retrospective cohort study including patients who underwent AP ablation between 2013 and 2018. Cox proportional hazards model was used to examine the association between patient and procedural characteristics and recurrence during follow-up. Results: From 558 AP ablation procedure, 542 (97%) were acutely successful. During a median follow-up of 0.4 (interquartile range, 0.1–1.4) years, there were 42 (8%) patients with documented recurrence. On univariate analysis, early recurrence was associated with younger age, congenital heart disease, multiple AP, AP location (right sided and posteroseptal versus left sided), cryoablation (versus radiofrequency), empirical ablation, the lack of full power radiofrequency lesions (<50 W), radiofrequency consolidation time <90 seconds and the use of fluoroscopy without a 3-dimensional electroanatomic mapping system. On multivariable analysis, only multiple AP (hazard ratio, 2.78 [95% CI, 1.063–4.74]) and radiofrequency consolidation time < 90 seconds (hazard ratio, 4.38 [95% CI, 1.92–9.51]) remained significantly associated with early recurrence; this association remained true when analyzed in subgroups by pathway location for right and left free wall AP. Conclusions: In our institutional experience, radiofrequency consolidation time <90 seconds after ablation of AP was associated with an increased risk of early recurrence.

5043 Background: The survival benefit of D in mCRPC is modest. CDK4/6 inhibitors such as R have shown synergistic activity with taxanes in pre-clinical cancer models. We sought to determine the safety and efficacy of R + D + P in mCRPC patients (pts). Methods: This was a Ph 1b/2 multicenter, open-label single arm trial of mCRPC pts with progression (PD) on ≥ 1 prior androgen receptor signaling inhibitor (ARSi) who had not previously received D for mCRPC (NCT02494921). Pts were treated with escalating doses of R in combination with D + P for 6-9 cycles, followed by single agent maintenance R until radiographic or clinical PD. The Ph 2 primary endpoint was 6-month (mo) radiographic progression-free survival (rPFS) rate by PCWG2 criteria, with a target rate of 55% and null hypothesis of 35%. Ph 2 pts underwent baseline circulating tumor cell (CTC) enumeration and genome sequencing (Epic Sciences). Cox proportional hazard model and log-rank test were used to test for associations between rPFS and CTC burden and copy number (CN) variants, respectively. Results: 43 pts were enrolled from 11/2015 to 6/2019. Median age was 68 (range 55-84). 20.9% of pts had visceral metastases. 33 (77%) had PD on prior abiraterone, 27 (63%) on enzalutamide, and 17 (40%) on both. In Ph 1b, 19 pts were enrolled. In the first cohort (D 75 mg/m2 day [d] 1, R 200 mg/d d2-14 of every 21d cycle), 2 pts experienced DLTs (febrile neutropenia [FN] and grade 4 neutropenia). With an alternative dosing schema of D 60 mg/m2 on d1, and R daily on d1-4 and 8-15 of cycle, with daily G-CSF support on d5-7, the MTD was not reached and D 60 mg/m2 + R 400 mg/d was chosen as the recommended Ph 2 dose (RP2D). In total, 30 pts were treated at RP2D; median number of D cycles was 8.5 and 60% went on to receive maintenance R. The Ph 2 primary endpoint was met with a 6-mo rPFS rate of 65% (95% CI 50-85%). Median rPFS was 8.0 mos (95% CI 4.1-10.0). PSA response rate (RR) defined as ≥50% reduction was 27.6% (95% CI 12.7-47.2%) and objective RR was 30.8% (95% CI 9.1-61.4%). Among pts treated at RP2D, the most common grade ≥3 treatment-related adverse events were neutropenia (n= 11, 36.7%), lymphocytopenia (n=3, 10%); no cases of FN were observed. Baseline CTC burden was associated with an increased risk of radiographic PD or death (HR 1.038, 95% CI 1.001-1.074, p = 0.038). Pts harboring CTCs without MYC (4/11 pts) or CDK6 CN gain (7/11 pts) had prolonged rPFS compared to those with gene amplification (median rPFS 10.76 vs 4.11 mos, p = 0.03, and 7.01 vs 1.92 mos, p = 0.053, respectively). Conclusions: The combination of R + D was well tolerated and showed promising activity in mCRPC pts who had progressed on an ARSi. The Ph 2 study met its primary endpoint, with an encouraging 6-mo rPFS rate of 65%. Lack of MYC or CDK6 amplification on CTC sequencing was associated with longer rPFS.

Abstract Introduction Improvements in multi-modal therapies have increased survival rates for older adults diagnosed with B-cell Non-Hodgkin Lymphoma (B-NHL). Despite this success, B-NHL survivors are at an increased risk for developing long-term and late complications of these therapies thereby compromising survival. Several studies have reported an increased risk in diabetes mellitus (DM) among long-term survivors of Hodgkin lymphoma and pediatric cancers. However, there are limited data on the risk of DM and its risk factors in older adults following treatment for B-NHL. Using data from the Utah Population Database, we evaluated the association between treatment for B-NHL and DM risk and furthermore compared this risk to a matched Utah general population. We hypothesized that the risk of DM among B-NHL survivors would be significantly increased compared to the general population. Methods Adult (age >18 years at diagnosis) survivors of primary B-NHL living in Utah at the time of diagnosis between 1997-2013, without a previous diagnosis of DM, and matched (1:4) to individuals without a prior history of DM from the Utah general population for birth year, birth state, and sex were included. New DM diagnoses were identified for all-time, 0-1, 1-5, and 5-10 years following a diagnosis of B-NHL. Adjusting for sex, race, baseline body mass index (BMI), and Charlson Comorbidity Index (CCI) scores, multivariate Cox proportional hazard analysis was performed to estimate the adjusted hazard ratio (aHR) of DM in B-NHL survivors compared with that in matched non-B-NHL individuals. Risk factors for DM were evaluated, including age at diagnosis, race, sex, BMI at baseline, family history of DM, cancer stage at diagnosis, and treatment modality. The risk of developing DM during all-time, 0 to 1, 1 to 5, and 5 to 10 years follow-up after adjusting for demographic variables was analyzed by age (< 40, 40-65, and >65 years) at diagnosis of B-NHL. Results The study population included 3,970 B-NHL survivors and 19,821 matched individuals from the general population. At the time of diagnosis, the majority of B-NHL patients were age 60 or greater (61.4%), had diffuse large B-cell lymphoma (46%) or follicular lymphoma (26.4%), distant cancer stage (50.1%), and received chemotherapy (27.5%). DM was diagnosed in 897 (22.6%) B-NHL survivors and 3,253 (16.4%) non-B-NHL adults. The majority in both groups were male (B-NHL: 55.5%; controls: 55.5%), white (B-NHL: 97.4%; controls: 93.8%), overweight [BMI 25-29.9 kg/m2 (B-NHL: 40.7%; controls: 40.6%)] or obese [BMI ≥30 kg/m2 (B-NHL: 21.8%; controls: 18.5%)]. The risk of developing DM among B-NHL survivors compared to the control group was significantly increased over all time (HR, 1.34; 95% CI 1.24 - 1.44) and the 0 to 1 year follow-up period (HR, 1.28; 95% CI 1.15 - 1.43)(Table 1). Multivariable analysis for DM risk showed that age 40-65 years and BMI ≥25 were factors independently associated with developing DM at all-time, 0 to 1, 1 to 5, and 5 to 10 years after diagnosis of B-NHL. Male sex and a family history of DM were significantly associated with development of DM during all time, 1 to 5, and 5 to 10 year follow-up periods. Distant cancer stage at diagnosis was a significant risk factor for DM at all time and 1 to 5 years while receipt of chemotherapy only or chemotherapy with radiation were significantly associated with development of DM at 5 to 10 years after diagnosis of B-NHL (estimated aHR and CIs are shown in Table 2). There was no significant association between race and the development of DM. Conclusion Adult survivors of B-NHL have an overall significantly higher risk of developing DM in the first year and over all time following a diagnosis of B-NHL compared to the general population. Age 40 to 65 years and BMI ≥25 were significant risk factors for DM across all follow-up periods while treatment with chemotherapy only or chemotherapy with radiation significantly increased the risk of DM 5-10 years after diagnosis of B-NHL. Race did not appear to be a risk factor for DM but this result may reflect the homogeneity of our study population. These findings contribute important information to the existing literature regarding the risk of developing DM in adult B-NHL survivors and provide foundation for the development of screening and management guidelines for DM in the B-NHL survivor population.

Tract Infections

Background: Catheter associated urinary tract infections (CAUTIs) are the most common causes of UTIs in postoperative cases. Many risk factors are associated with its incidence. The present study was conducted with the aim to determine the related risk factors and to identify the causative agents contributing to the urinary tract infection.Methods: This prospective study was conducted on 210 patients meeting the requirements of inclusion criteria during September 2012 to February 2014. Detailed history of the patients was recorded. Urine culture was done at different time intervals to identify the causative agent suggestive to CAUTI. Univariate analyses of the association of each variable with CAUTI and multivariable logistic regression were done to predict CAUTI outcome.Results: The mean age of study participants was 51.61 years. Among them 141 were males and 69 were female patients. On univariate analysis purpose for urine catheterization, place of catheterization, breach in the closed system of drainage, duration of catheterization, hemoglobin value less than 10, raised renal parameters with serum creatinine more than 1.5 were all significantly associated with development of CAUTI (p value 0.000). Sex of the patient (p value 0.279) and catheter size (p value 0.279) was not found to have a significant correlation with increased risk of CAUTI. On multivariate analysis, age, catheter size, diabetes, duration of catheterization, a breach in the closed system of catheter drainage and sex were found to be the significant risk factors associated with CAUTI (p<0.05).Conclusion: An understanding of the risk factors in development of CAUTI, significantly helps in reducing the additional burden on the health care system. Measures such as shortening the duration of catheterization, strict control of diabetes and sterile precautions in insertion and maintenance of indwelling catheters can help in prevention CAUTI.

SummaryOvarian cancer cells appear to be capable of both thrombin formation and induction of fibrin degradation which may be essential prerequisites for the development of deep vein thrombosis (DVT) as well as the spread of malignancy. To study further this coagulation – cancer interaction in 60 patients with untreated ovarian cancer of FIGO stage I-IV the incidence of DVT was recorded pre-operatively, postoperatively on day 1, 3, 5, 7, 10, before each of six cycles of Cisplati- num/Epirubicin/Cyclophosphamide chemotherapy, during follow-up and in the post-operative period of second look surgery. In addition, blood coagulation tests results were determined prospectively. Two patients were excluded from these calculations due to previous DVT 5 to 6 weeks before the diagnosis of ovarian cancer but all patients were eligible for surgery and randomized to receive either daily low molecular weight heparin (LMWH) (n = 28) or unfractionated heparin (UFH) (n = 32) for perioperative thrombosis prophylaxis until the 7th postoperative day. According to the FIGO stage, patients were equally distributed in the 2 heparin treatment groups. The predictive value of pre-operative coagulation test results, clinical parameters, and type of heparin used were tested in univariate and multivariate analysis for development of post-operative DVT and overall patients survival. Impedance plethysmography for DVT screening was used. The presence of DVT was then confirmed by phlebography. Only D-dimer and fibrinogen levels were correlated significantly with the FIGO stage while antithrombin, protein C, and plasminogen activator inhibitor activity were not. The incidence of DVT was 6.7% (4/60) up to the 7th and 8.3% (5/60) between the 8th and 29th post-operative day. DVT occurred in 10.6 % (5/47) during chemotherapy. Pre-operative coagulation test results, the type of heparin used, and clinical parameters were not significant risk factors for post-operative DVT development in univariate analysis. The D-dimer and fibrinogen levels were significant risk factors for reduced overall survival in univariate analysis but only the FIGO stage was an independent predictor (in multivariate analysis). After a median follow up of 26.5 months (min. 8 months, max. 41 months), 21.4% of LMWH treated and 37.5% of UFH-treated patients died of cancer (p = 0.26). Pre-operative test results were neither predictive for DVT nor the outcome of cancer but patients showed an improved though not statistically significant overall survival after LMWH treatment.
