A randomized phase II evaluation of weekly gemcitabine plus pazopanib versus weekly gemcitabine alone in the treatment of persistent or recurrent epithelial ovarian, fallopian tube or primary peritoneal carcinoma.

OBJECTIVE: Angiogenesis inhibition is a valuable strategy for ovarian cancer (EOC). Pazopanib (paz) is a potent small molecular inhibitor of VEGF-1, -2, -3, PDGFR, c-kit, and has activity as a single agent in ovarian cancer. We designed a trial to assess the benefit of adding paz to gemcitabine (gem) in patients with recurrent EOC. METHODS: An open-label, randomized, multi-site, phase 2 trial was conducted (NCT01610206) including patients with platinum resistant or sensitive disease, ≤ 3 prior lines of chemotherapy, and measurable/evaluable disease. Patients were randomly assigned to weekly gem 1000 mg/m2 on days 1 and 8 of a 21 day cycle, with or without paz 800 mg QD, stratified by platinum sensitivity and number of prior lines (1 vs 2 or 3). The primary endpoint was PFS. RESULTS: 148 patients were enrolled 2012-2017. Median age was 63 years (30-82); 60% were platinum resistant; median surveillance was 13 months (0.4-54 months). Median PFS was 5.3 (95% CI, 4.2-5.8) vs 2.9 months (95% CI, 2.1-4.1) in the gem arm. The PFS effect was most pronounced in the platinum resistant group (5.32 vs 2.33 months Tarone-Ware p < 0.001). There was no difference in OS. Overall RR (PR 20% vs 11%, Chi-squre p = 0.02) and DCR (80% vs 60%, Chi-square p < 0.001) were higher in the combination. High grade AEs in the combination arm included ≥ Grade 3: hypertension (15%), neutropenia (35%), and thrombocytopenia (12%). CONCLUSIONS: The addition of paz to gem enhanced anti-tumor activity; those with platinum-resistant disease derived the most benefit from combination therapy, even in the setting of receiving prior bevacizumab.

Intraperitoneal chemotherapy following neoadjuvant chemotherapy and optimal interval tumor reductive surgery for advanced ovarian cancer.

OBJECTIVES: Intraperitoneal (IP) chemotherapy following neoadjuvant chemotherapy (NACT) and interval tumor reductive surgery (TRS) for advanced ovarian cancer is feasible, however, the impact on disease outcomes remains unclear. We compare outcomes of patients treated with IP chemotherapy versus intravenous (IV) chemotherapy following NACT and interval TRS. METHODS: In this retrospective review, patients with advanced ovarian cancer were included if they received NACT followed by optimal interval TRS between 1/2004 and 4/2017. Patients were excluded if they had an ECOG PS >1, received >6 cycles of NACT or postoperative chemotherapy, and/or received bevacizumab during primary therapy. Primary outcomes were progression free survival (PFS) and overall survival (OS). RESULTS: There were 134 patients included in this study, 37 (28%) received IP and 97 (72%) received IV chemotherapy postoperatively. Patients in the IV group were older (median 66.3 vs 59.7 years, p = 0.0039) though there were no differences in BMI, race, BRCA status, stage, or histology. Median PFS was 3 months longer in the IP group (14.5 versus 11.5 months, p = 0.028) however there was no significant difference in OS. On univariate analysis, increasing number of NACT cycles (HR 1.914, 95% CI 1.024-3.497) and residual disease at completion of TRS (HR 1.541, 95% CI 1.042-2.248) were associated with decreased PFS; IP chemotherapy was associated with increased PFS (HR 0.633, 95% CI 0.414-0.944). These associations remained on multivariate analysis. Toxicity was comparable between the groups. CONCLUSIONS: IP after NACT and optimal interval TRS was associated with in improved PFS compared to IV chemotherapy without significant differences in toxicity.

Quality of life is significantly associated with survival in women with advanced epithelial ovarian cancer: An ancillary data analysis of the NRG Oncology/Gynecologic Oncology Group (GOG-0218) study.

OBJECTIVE: Evaluate association between baseline quality of life (QOL) and changes in QOL measured by FACT-O TOI with progression-free disease (PFS) and overall survival (OS) in advanced epithelial ovarian cancer (EOC). METHODS: Patients enrolled in GOG-0218 with completed FACT-O TOI assessments at baseline and at least one follow-up assessment were eligible. Baseline FACT-O TOI scores were sorted by quartiles (Q1-4) and outcomes compared between Q1 and Q2-4 with log-rank statistic and multivariate Cox regression adjusting for age, stage, post-surgical residual disease size, and performance status (PS). Trends in FACT-O TOI scores from baseline to the latest follow-up assessment were evaluated for impact on intragroup (Q1 or Q2-4) outcome by log-rank analysis. RESULTS: Of 1152 eligible patients, 283 formed Q1 and 869 formed Q2-4. Mean baseline FACT-O TOI scores were 47.5 for Q1 vs. 74.7 for Q2-4 (P<0.001). Q1 compared to Q2-4 had worse median OS (37.5 vs. 45.6months, P=0.001) and worse median PFS (12.5 vs. 13.1months, P=0.096). Q2-4 patients had decreased risks of disease progression (HR 0.974, 95% CI 0.953-0.995, P=0.018), and death (HR 0.963, 95% CI 0.939-0.987, P=0.003) for each five-point increase in baseline FACT-O TOI. Improving versus worsening trends in FACT-O TOI scores were associated with longer median PFS (Q1: 12.7 vs. 8.6months, P=0.001; Q2-4: 16.7 vs. 11.1months, P<0.001) and median OS (Q1: 40.8 vs. 16months, P<0.001; Q2-4: 54.4 vs. 33.6months, P<0.001). CONCLUSIONS: Baseline FACT-O TOI scores were independently prognostic of PFS and OS while improving compared to worsening QOL was associated with significantly better PFS and OS in women with EOC.

Progression-free and overall survival in ovarian cancer patients treated with CVac, a mucin 1 dendritic cell therapy in a randomized phase 2 trial.

BACKGROUND: CAN-003 was a randomized, open-label, Phase 2 trial evaluating the safety, efficacy and immune outcomes of CVac, a mucin 1 targeted-dendritic cell (DC) treatment as a maintenance therapy to patients with epithelial ovarian cancer (EOC). METHODS: Patients (n = 56) in first (CR1) or second clinical remission (CR2) were randomized (1:1) to standard of care (SOC) observation or CVac maintenance treatment. Ten doses were administered over 56 weeks. Both groups were followed for progression-free survival (PFS) and overall survival (OS). RESULTS: Fifty-six patients were randomized: 27 to SOC and 29 to CVac. Therapy was safe with only seven patients with Grade 3-4 treatment-emergent adverse events. A variable but measurable mucin 1 T cell-specific response was induced in all CVac-treated and some standard of care (SOC) patients. Progression free survival (PFS) was not significantly longer in the treated group compared to SOC group (13 vs. 9 months, p = 0.36, hazard ratio [HR] = 0.73). Analysis by remission status showed in the CR1 subgroup a median PFS of 18 months (SOC) vs. 13 months (CVac); p = 0.69 (HR = 1.18; CI 0.52-2.71). However CR2 patients showed a longer median PFS in the CVac-treated group (median PFS not yet reached, >13 vs. 5 months; p = 0.04, HR = 0.32 CI). OS for CR2 patients at 42 months of follow-up showed a difference of 26 months for SOC vs. > 42 months for CVac-treated (as median OS had not been reached; HR = 0.17 (CI 0.02-1.4) with a p = 0.07). CONCLUSIONS: CVac, a mucin 1-dendritic cell maintenance treatment was safe and well tolerated in ovarian cancer patients. A variable but observed CVac-derived, mucin 1-specific T cell response was measured. Notably, CR2 patients showed an improved PFS and lengthened OS. Further studies in CR2 ovarian cancer patients are warranted (NCT01068509). TRIAL REGISTRATION: NCT01068509. Study Initiation Date (first patient screened): 20 July 2010. Study Completion Date (last patient observation): 20 August 2013, the last patient observation for progression-free survival; 29 April 2015, the last patient was documented regarding overall survival.

Evidence of estrogenic endocrine disruption in smallmouth and largemouth bass inhabiting Northeast U.S. national wildlife refuge waters: A reconnaissance study.

Intersex as the manifestation of testicular oocytes (TO) in male gonochoristic fishes has been used as an indicator of estrogenic exposure. Here we evaluated largemouth bass (Micropterus salmoides) or smallmouth bass (Micropterus dolomieu) form 19 National Wildlife Refuges (NWRs) in the Northeast U.S. inhabiting waters on or near NWR lands for evidence of estrogenic endocrine disruption. Waterbodies sampled included rivers, lakes, impoundments, ponds, and reservoirs. Here we focus on evidence of endocrine disruption in male bass evidenced by gonad histopathology including intersex or abnormal plasma vitellogenin (Vtg) concentrations. During the fall seasons of 2008-2010, we collected male smallmouth bass (n=118) from 12 sites and largemouth bass (n=173) from 27 sites. Intersex in male smallmouth bass was observed at all sites and ranged from 60% to 100%; in male largemouth bass the range was 0-100%. Estrogenicity, as measured using a bioluminescent yeast reporter, was detected above the probable no effects concentration (0.73ng/L) in ambient water samples from 79% of the NWR sites. Additionally, the presence of androgen receptor and glucocorticoid receptor ligands were noted as measured via novel nuclear receptor translocation assays. Mean plasma Vtg was elevated (>0.2mg/ml) in male smallmouth bass at four sites and in male largemouth bass at one site. This is the first reconnaissance survey of this scope conducted on US National Wildlife Refuges. The baseline data collected here provide a necessary benchmark for future monitoring and justify more comprehensive NWR-specific studies.

Selective cardiac surveillance in patients with gynecologic cancer undergoing treatment with pegylated liposomal doxorubicin (PLD).

OBJECTIVE: The study objective was to examine the safety and cost savings of selective cardiac surveillance (CS) during treatment with pegylated liposomal doxorubicin (PLD). METHODS: A retrospective, dual institution study of women receiving PLD for the treatment of a gynecologic malignancy was performed. The study period was 2002-2014. At both institutions, a selective strategy for CS was implemented in which only high-risk women with a cardiac history or with symptoms suggestive of cardiac toxicity during PLD treatment underwent a cardiac evaluation. Patient demographics, clinical and treatment history were evaluated. Cost analyses were performed utilizing professional/technical fee rates for echocardiogram and multi-gated acquisition scan for each state. RESULTS: PLD was administered in 184 women. The mean patient age was 62.7years, and 79% were treated for recurrent ovarian or peritoneal carcinoma. The median cumulative administered dose of PLD was 300mg/m(2); 24 received >550mg/m(2). The median follow-up time was 20months. Of the 184 patients, the majority (n=157, 85.3%) did not undergo either an initial cardiac evaluation or surveillance during or post-PLD treatment. Fifty-three patients considered high risk for anthracycline-induced cardiotoxicity underwent CS. Only three patients (1.6%) in the entire cohort developed CHF that was possibly related to PLD treatment; all had significant pre-existing cardiac risk factors. Selective instead of routine use of CS in the study population resulted in a cost savings of $182,552.28. CONCLUSION: Utilizing cardiac surveillance in select women undergoing PLD treatment for gynecologic malignancies resulted in significant health care cost savings without adversely impacting clinical outcomes.

A prognostic nomogram to predict overall survival in women with recurrent ovarian cancer treated with bevacizumab and chemotherapy.

OBJECTIVE: To develop a nomogram to predict overall survival (OS) in women with recurrent ovarian cancer treated with bevacizumab and chemotherapy. METHODS: A multicenter retrospective study was conducted. Potential prognostic variables included age; stage; grade; histology; performance status; residual disease; presence of ascites and/or pleural effusions; number of chemotherapy regimens, treatment-free interval (TFI) prior to bevacizumab administration, and platinum sensitivity. Multivariate analysis was performed using Cox proportional hazards regression. The predictive model was developed into a nomogram to predict five-year OS. RESULTS: 312 women with recurrent ovarian cancer treated with bevacizumab and chemotherapy were identified; median age was 59 (range: 19-85); 86% women had advanced stage (III-IV) disease. The majority had serous histology (74%), high grade cancers (93.5%), and optimal cytoreductions (69.5%). Fifty-one percent of women received greater than two prior chemotherapeutic regimens. TFI (AHR=0.98, 95% CI 0.97-1.00, p=0.022) was the only statistically significant predictor in a multivariate progression-free survival (PFS) analysis. In a multivariate OS analysis, prior number of chemotherapy regimens, TFI, platinum sensitivity, and presence of ascites were significant. A nomogram to predict five-year OS was constructed and internally validated (bootstrap-corrected concordance index=0.737). CONCLUSION: Our multivariate model identified prior number of chemotherapy regimens, TFI, platinum sensitivity, and the presence of ascites as prognostic variables for OS in women with recurrent ovarian cancer treated with bevacizumab combined with chemotherapy. Our nomogram to predict five-year OS may be used to identify women who may benefit from bevacizumab and chemotherapy, but further validation is needed.

ADAM metallopeptidase domain 17 (ADAM17) is naturally processed through major histocompatibility complex (MHC) class I molecules and is a potential immunotherapeutic target in breast, ovarian and prostate cancers.

Selection of suitable antigens is critical for the development of cancer vaccines. Most desirable are over-expressed cell surface proteins that may serve as targets for both antibodies and T cells, thus maximizing a concerted immune response. Towards this goal, we characterized the relevance of tumour necrosis factor-α-converting enzyme (ADAM17) for such targeted therapeutics. ADAM17 is one of the several metalloproteinases that play a key role in epidermal growth factor receptor (EGFR) signalling and has recently emerged as a new therapeutic target in several tumour types. In the present study, we analysed the expression profile of ADAM17 in a variety of normal and cancer cells of human origin and found that this protein is over-expressed on the surface of several types of cancer cells compared to the normal counterparts. Furthermore, we analysed the presentation of a human leucocyte antigen (HLA)-A2-restricted epitope from ADAM17 protein to specific T cells established from normal donors as well as ovarian cancer patients. Our analysis revealed that the HLA-A2-restricted epitope is processed efficiently and presented by various cancer cells and not by normal cells. Tumour-specific T cell activation results in the secretion of both interferon-γ and granzyme B that can be blocked by HLA-A2 specific antibodies. Collectively, our data present evidence that ADAM17 can be a potential target antigen to devise novel immunotherapeutic strategies against ovarian, breast and prostate cancer.

Desmoplastic small round cell tumor masquerading as advanced ovarian cancer.

Desmoplastic small round cell tumor (DSRCT) is a rare abdominal malignancy usually diagnosed in young adult males. Most patients have widespread disease at presentation, with an organ of origin difficult to ascertain. A 33-year-old female presented to her gynecologist with complaints of suprapubic pressure, abdominal pain, and increased abdominal girth. She had a large intraabdominal tumor on ultrasound, thought to be ovarian cancer. She underwent surgical exploration, which confirmed a malignancy, but the exact etiology was uncertain. Final pathology was consistent with DSRCT. DSRCT is a rare malignancy that can mimic other more commonly seen tumors such as lymphoma and ovarian cancer. When encountering an extensive intraabdominal malignancy of uncertain etiology, DSRCT should be in the differential diagnosis.

A multi-institutional evaluation of factors predictive of toxicity and efficacy of bevacizumab for recurrent ovarian cancer.

While bevacizumab has shown activity in recurrent ovarian cancer, a higher than expected incidence of bowel perforations has been reported in recent trials. We sought to determine factors associated with toxicity and tumor response in patients with relapsed ovarian cancer treated with bevacizumab. A retrospective review of patients with recurrent ovarian cancer treated with bevacizumab was undertaken. Response was determined radiographically and through CA125 measurements. Statistical analysis to determine factors associated with toxicity and response was performed. Sixty-two eligible patients were identified. The cohort had received a median of 5 prior chemotherapy regimens. Single-agent bevacizumab was administered to 12 (19%), while 50 (81%) received the drug in combination with a cytotoxic agent. Grade 3-5 toxicities occurred in 15 (24%) patients, including grade 3-4 hypertension in 4 (7%), gastrointestinal perforations in 7%, and chylous ascites in 5%. Development of chylous ascites and gastrointestinal perforations appeared to correlate with tumor response. The overall response rate was 36% (4 complete response, 17 partial response), with stable disease in 40%. A higher objective response rate was seen in the bevacizumab combination group compared to single-agent treatment (43% vs 10%) (P = 0.07). However, 29 grade 3-5 toxic episodes were seen in the combination group vs only 1 in the single-agent bevacizumab cohort (P = 0.071). We conclude that bevacizumab demonstrates promising activity in recurrent ovarian cancer. The addition of a cytotoxic agent to bevacizumab improved response rates at the cost of increased toxicity. Gastrointestinal perforations occurred in 7%. The perforations occurred in heavily pretreated patients who were responding to therapy.

Cost-effectiveness of adjuvant radiotherapy in intermediate risk endometrial cancer.

OBJECTIVES: Endometrial cancer is the most common gynecologic malignancy in the United States. Adjuvant radiotherapy in patients with intermediate risk disease (stage IB, IC, and occult stage II) is controversial. Despite no proven survival advantage, a significant number of women undergo this treatment annually. The purpose of this study was to compare the estimated health and economic outcomes for adjuvant whole pelvic radiotherapy to no treatment with salvage therapy for recurrence. METHODS: A decision analytic model was created to estimate the costs of adjuvant pelvic radiotherapy versus no adjuvant radiotherapy in patients with intermediate risk endometrial cancer. Data used was gathered from published literature and institutional data on costs. The model incorporates complications, recurrence rates, treatment of recurrence, and survival in each group. RESULTS: In the base case analysis, adjuvant pelvic radiation reduced the recurrence rate by 50%. Cost-effectiveness as measured by cost per recurrence prevented was highly sensitive to the probability of recurrence and the efficacy of adjuvant therapy. In our model the mean costs of Strategy 1 with observation and treatment reserved until the time of recurrence would be $5016. In contrast the mean cost of Strategy 2 which incorporated adjuvant radiotherapy would be $21,159. Cost per recurrence prevented based on the incremental cost-effectiveness is thus $225,215. In the highest risk subgroup, using the upper limit of the 90% confidence limit of efficacy seen in GOG Protocol 99, cost/recurrence prevented was approximately $50,000. Results did not differ when using parameters solely from GOG 99 or PORTEC. CONCLUSIONS: Although adjuvant pelvic radiation does not appear to improve survival for intermediate risk endometrial cancer patients, it does prevent recurrences, at a net positive cost compared to no therapy. Data are not currently available to incorporate quality of life information into cost-effectiveness analyses. Obtaining such data would allow cost/quality-adjusted life year gained to be estimated. This information is necessary to determine if the extra costs of adjuvant radiotherapy in patients with intermediate risk endometrial cancer are acceptable by current health care policy standards.

Salvage of isolated vaginal recurrences in women with surgical stage I endometrial cancer: a multiinstitutional experience.

The objective of this study was to evaluate the treatment outcomes and risk factors of women with surgical stage I endometrial adenocarcinoma who were initially treated with surgery alone and subsequently developed isolated vaginal recurrences. Patients with surgical stage I endometrial adenocarcinoma diagnosed from 1975 to 2002 were identified from tumor registry databases at seven institutions. All patients were treated with surgery alone including a total hysterectomy, bilateral salpingo-oophorectomy, pelvic (+/- para-aortic) lymph node dissection, and peritoneal cytology and did not receive postoperative radiation therapy. Vaginal recurrences were documented histologically. Metastatic disease in the chest and abdomen was excluded by radiologic studies. Overall survival was calculated by the Kaplan-Meier method. Sixty-nine women with surgical stage I endometrial cancer with isolated vaginal recurrences were identified. Of the 69 patients, 10 (15%) were diagnosed with stage IA disease, 43 (62%) were diagnosed with stage IB disease, and 16 (23%) were diagnosed with stage IC disease. Patients diagnosed with grade 1 disease were 22 (32%), grade 2 disease were 26 (38%), and grade 3 disease were 21 (30%). Among women, 81% with isolated vaginal recurrences were salvaged with radiation therapy. The mean time to recurrence was 24 months, and the mean follow-up was 63 months. Among women, 18% died from subsequent recurrent disease. The 5-year overall survival was 75%. The majority of isolated vaginal recurrences in women with surgical stage I endometrial cancer can be successfully salvaged with radiation therapy, further questioning the role of adjuvant therapy for patients with uterine-confined endometrial cancer at the time of initial diagnosis.

Comparison of gracilis and rectus abdominis myocutaneous flap neovaginal reconstruction performed during radical pelvic surgery: flap-specific morbidity.

To compare flap-specific complications of gracilis myocutaneous (GM) and rectus abdominis myocutaneous (RAM) flap neovaginal reconstructions after radical pelvic surgery. The study was a single-institution retrospective review of patients undergoing concurrent radical pelvic surgery with GM or RAM neovaginal reconstructions performed on a gynecological oncology service, 1978-2003. Flap-specific complications were compared between the techniques. Forty-four GM and 32 RAM neovaginal reconstructions were analyzed: plastic surgeons developed 12 (27%) GM and 4 (13%) RAM flaps, with all other flaps performed by gynecological oncologists. Primary procedures included 54 (71%) total pelvic exenterations, with partial exenterations or radical vulvovaginectomies in 16 (21%) and 6 (8%) patients, respectively. Forty (53%) patients had received radiation and 28 (36%) received chemoradiation before radical surgery. There were no significant differences in patient characteristics, other than more frequent use of continent urinary conduits (P < 0.001) and a trend for more frequent sidewall radiation (P < 0.1) in the RAM group, reflecting use in more recent patients (P < 0.001). Median follow-up is 28 months (range: 2 weeks to 216 months), with 5% acute operative mortality. Flap-specific complications were significantly increased in GM patients (P < 0.03). Overall flap loss was significantly increased in GM patients (P < 0.02). Thirty (59%) of 51 patients surviving for more than 12 months reported coitus, with no significant difference between the groups. Because of lower overall incidence of flap-specific complications and significantly lower incidence of flap loss compared with GM flap, RAM flap has become our technique of choice for neovaginal reconstruction concurrent with radical pelvic surgery.

Use of trastuzumab in the treatment of metastatic endometrial cancer.

Systemic therapy of metastatic endometrial cancer is relatively ineffective. Response rates to chemotherapy and hormonal therapy in published studies range from 11% to 57%, but most responses are partial and of limited duration. In this case, we present a 76-year-old woman with stage IIIA endometrial adenocarcinoma who was initially treated with surgery and pelvic radiation. She developed multiple pulmonary metastases. She was treated with weekly paclitaxel chemotherapy. Immunostaining revealed that the primary endometrial cancer overexpressed HER-2/neu. Trastuzumab was added to the regimen, and a dramatic partial response was achieved. After a second pulmonary relapse following discontinuation of prior therapy, she was again successfully treated with trastuzumab in combination with paclitaxel and then docetaxel. Therefore, trastuzumab may be a useful adjuvant to taxane-based chemotherapy in some patients with metastatic endometrial cancers that overexpress HER-2/neu.

Phase I/II trial of intravenous Doxil and whole abdomen hyperthermia in patients with refractory ovarian cancer.

OBJECTIVE: A phase I/II study of Doxil combined with whole abdomen hyperthermia was conducted in patients with refractory ovarian cancer. Liposomal doxorubicin combined with hyperthermia has been shown to increase both liposomal delivery and drug extravasation into tumour xenografts resulting in enhanced cytotoxic effects. PATIENTS AND METHODS: Thirty patients with either recurrent or persistent epithelial ovarian cancer were enrolled. All patients had either measurable or assessable disease. Patients received intravenous (IV) Doxil at a dose of 40 mg m-2 as a 1-h infusion followed by whole abdomen hyperthermia. The phase I portion of the study was performed to determine the maximal tolerated dose (MTD) of hyperthermia. Quality of life (QoL) was performed at baseline, prior to each cycle and every 3 months. Plasma pharmacokinetic studies were performed with the first cycle. RESULTS: Ten patients participated in the phase I portion of the study which demonstrated that the MTD of hyperthermia was 60 min after either average vaginal and rectal temperatures of 40 degrees C had been achieved or after 30 min of power application, whichever was shorter. All 30 patients were either paclitaxel and/or platinum resistant initially or developed resistant disease. The median number of prior chemotherapeutic regimens was three (range 2-8) and six patients had been previously treated with Doxil. There were three partial responses for a response rate of 10% (95% CI: [2%, 27%]) and eight patients (27%; 95% CI: [12%, 46%]) had disease stabilization. The median time to progression or death was 3.4 months (95% CI: [2.6, 5.2]) and the median survival was 10.8 months (95% CI: [8.8, 17.4]). Twelve patients (40%) experienced palmar-plantar erythrodysesthesia (PPE), but only four (13%) experienced grade 3-4 PPE toxicity. Doxil systemic exposure was higher in those with grade 3-4 PPE compared to those with no PPE. None of the patients had grade 3-4 thermal toxicity due to hyperthermia. QoL was not decreased in patients responding to therapy. CONCLUSIONS: Therapy with intravenous Doxil and whole abdomen hyperthermia for patients with platinum/paclitaxel resistant ovarian cancer is feasible and does not negatively impact quality of life.

Prospective assessment of quality of life in ovarian cancer patients receiving whole abdomen hyperthermia and liposomal doxorubicin.

PURPOSE: Prospective assessment of quality of life (QoL) in patients with refractory, residual or recurrent ovarian cancer receiving whole abdomen hyperthermia and intravenous liposomal doxorubicin chemotherapy. METHODS: Treatment consisted of six cycles of intravenous liposomal doxorubicin at 40 mg m2 followed by whole abdomen hyperthermia with each cycle delivered every 4 weeks. QoL assessment was performed at baseline, prior to each cycle of chemotherapy and every 3 months during follow-up using self-administered questionnaires. Global QoL was rated on a seven-point scale and specific domains of QoL, disease related symptoms and treatment related toxicity were rated on a four-point scale. RESULTS: Thirty-two patients were enrolled on the study and 129 QoL questionnaires were completed. Average age was 57.9 (range 45-76); nine patients had persistent and 23 recurrent disease. Ten patients completed six cycles of therapy. Three patients returned follow-up surveys. Subjects rated their overall QoL and health at baseline as above average with mean scores 5.10 (95% CI=4.62-5.58) and 4.66 (95% CI=4.23-5.08), respectively. No significant change in overall QoL was found between baseline and cycles 4-6 of therapy. Mean ratings of overall health and subject reported differences in QoL between cycles were not significantly changed during therapy. Limited follow-up data were available, but scores suggest possible improvement in QoL for patients completing all therapy. Subjects rated the greatest negative impact on QoL in areas of role functioning and social functioning, where the mean (SD) over all cycles was 2.00 (0.67) and 1.98 (0.70), respectively. For physical symptoms, fatigue and sleep disturbance had the most negative impact on QoL with means (SD) of 2.26 (0.62) and 1.91 (0.70). The moderate treatment related toxicity seen in this study did not significantly impact patients reported QoL. CONCLUSIONS: Patients with unfavourable ovarian cancer responding to intravenous liposomal doxorubicin and whole abdomen hyperthermia maintained above average QoL during therapy. Limited data on patients completing protocol therapy demonstrated possible improvement in QoL.

Rectus abdominis myocutaneous flaps for neovaginal reconstruction after radical pelvic surgery.

The objective of this article is to compare the flap-specific complications associated with vertical (VRAM) and transverse (TRAM) rectus abdominis myocutaneous flap vaginal reconstructions performed during radical pelvic procedures. A retrospective chart review was performed to identify all patients who underwent VRAM and TRAM neovaginal reconstructions performed on the Gynecologic Oncology Service at Duke University Medical Center. Flap-specific complications were compared between the two techniques. From 1988 to 2003, 14 VRAM and 18 TRAM flap neovaginal reconstructions were performed on 32 women during the course of 22 (68%) total pelvic exenterations, 8 (25%) partial exenterations, and 2 (6%) radical vulvovaginectomies. Twenty-eight (88%) patients had been previously treated with radiation therapy or concurrent chemoradiation. Associated procedures included continent urinary conduit in 21 (66%), rectosigmoid reanastomosis in 8 (25%), and intraoperative or postoperative sidewall radiation therapy in 7 (22%) of patients. Overall median survival was 14 months (range: 2-week postoperative death to 65 months), with two (6%) acute postoperative mortalities. Fifteen flap-specific complications occurred in 12 (38%) patients, with no significant differences in flap type. Abdominal wound complications included four (12%) superficial wound separations, while one (3%) patient had a fascial dehiscence associated with complex fistulas that contributed to her death, but no patient developed incisional hernia. One patient each developed > 50% flap loss after TRAM and < 50% flap loss after VRAM flap, respectively. Four (12%) patients developed vaginal stricture or stenosis, two (6%) required percutaneous drainage of pelvic abscess or hematoma, and two (6%) developed rectovaginal fistula. Univariate analysis revealed a trend for increasing flap loss with body mass index > 35 (P = 0.056, Fisher exact two-tailed test), but there were no significant associations with other patient characteristics or flap-specific complications. Thirteen (62%) of 21 patients who survived >12 months reported coitus. Both VRAM and TRAM are reliable techniques for neovaginal reconstructions after radical pelvic surgery and have a similar distribution of flap-specific complications involving the donor and recipient sites.

Polychlorinated biphenyl contamination and minisatellite DNA mutation rates of tree swallows.

The evidence that exposure to polychlorinated biphenyls (PCBs) leads to mutations is equivocal and controversial. Using multilocus DNA fingerprinting, we compared the mutation rate of tree swallows (Tachycineta bicolor) nesting at sites with high and low levels of contamination with PCBs. The upper Hudson River, USA, is highly contaminated with PCBs as a result of releases from two capacitor manufacturing plants in Hudson Falls and Fort Edward, New York, USA. Tree swallows nesting nearby have some of the highest known concentrations of PCBs in their tissues of any contemporary bird population (up to 114,000 ng PCB/g tissue). We found no difference in mutation rates between sites in New York with high PCB contamination and reference sites in Wisconsin, USA, and Ontario and Alberta, Canada, with known or presumably low levels of contamination. Thus, the mechanism behind altered reproductive behavior of tree swallows along the upper Hudson River is most likely physiological impairment, such as endocrine disruption, rather than mutation.

Platelet transfusion refractoriness associated with HPA-1a (Pl(A1)) alloantibody without coexistent HLA antibodies successfully treated with antigen-negative platelet transfusions.

BACKGROUND: Alloimmune-mediated refractoriness to platelet transfusion is most commonly due to antibody to HLA antigens in multiply transfused or multiparous patients. Published reports of poor transfusion response due to antibodies to platelet-specific antigens are rare and often confounded by the presence of coexistent antibodies against HLA antigens. CASE REPORT: A case is presented of a multiparous woman with acute myelogenous leukemia whose sole cause of transfusion refractoriness was antibody to platelet antigen HPA-1a. She responded dramatically to HPA-1a-negative platelet transfusion. CONCLUSION: This case provides strong serologic and clinical evidence that platelet transfusion refractoriness may result from antibodies to platelet-specific antigens.
