Phase I/II dose finding study of combination cisplatin and gemcitabine in patients with recurrent cervix cancer.

OBJECTIVES: To evaluate the toxicity and efficacy of cisplatin and gemcitabine in women with recurrent cervical cancer. METHODS: A multi-institutional phase I/II dose finding study of cisplatin and gemcitabine delivered to women with recurrent previously radiated cervical carcinoma. RESULTS: Twenty eight patients were enrolled. The mean and median age of patients was 51 years (age range 35 to 70 years). Chemotherapy was given on a 28-day cycle; cisplatin was administered at a fixed dose of 50 mg/m(2), day 1 and gemcitabine, days 1, 8, and 15. Gemcitabine doses started at 600 mg/m(2) (dose level 1) and were escalated by 100 mg/m(2)/dose level until 1000 mg/m(2) (dose level 5). Twenty seven patients were evaluable for toxicity and disease response, and 75 cycles of chemotherapy were administered. Toxicities were predominantly hematological; 18% of patients experienced grade 3 anemia, 37% grade 3 and 11% grade 4 leukopenia, 41% grade 3 neutropenia, and 26% grade 3 thrombocytopenia. The maximally tolerated dose (MTD) was not reached. One patient experienced a dose-limiting toxicity on dose level 2 (febrile neutropenia). One patient had a CR and 3 patients had a PR to therapy (15% response rate), 41% of patients had SD, and 44% had progression of cancer. Median survival was 11.9 months. CONCLUSION: Although this 28-day gemcitabine and cisplatin regimen in recurrent cervix cancer has tolerable toxicity, 21-day regimens are recommended because of improved practicality, higher dose intensity, and higher response rates.

A phase I clinical trial of continual alternating etoposide and topotecan in refractory solid tumours.

The goal of this phase I study was to develop a novel schedule using oral etoposide and infusional topotecan as a continually alternating schedule with potentially optimal reciprocal induction of the nontarget topoisomerase. The initial etoposide dose was 15 mg m(-2) b.i.d. days (D)1-5 weeks 1,3,5,7,9 and 11, escalated 5 mg per dose per dose level (DL). Topotecan in weeks 2,4,6,8,10 and 12 was administered by 96 h infusion at an initial dose of 0.2 mg m(-2) day(-1) with a dose escalation of 0.1, then at 0.05 mg m(-2) day(-1). Eligibility criteria required no organ dysfunction. Two dose reductions or delays were allowed. A total of 36 patients with a median age of 57 (22-78) years, received a median 8 (2-19) weeks of chemotherapy. At DL 6, dose-limiting toxicities consisted of grade 3 nausea, vomiting and intolerable fatigue. Three patients developed a line-related thrombosis or infection and one subsequently developed AML. There was no febrile neutropenia. There were six radiologically confirmed responses (18%) and 56% of patients demonstrated a response or stable disease, typically with only modest toxicity. Oral etoposide 35 mg m(-2) b.i.d. D1-5 and 1.8 mg m(-2) 96 h (total dose) infusional topotecan D8-11 can be administered on an alternating continual weekly schedule for at least 12 weeks, with promising clinical activity.

Randomized multicenter trial of natalizumab in acute MS relapses: clinical and MRI effects.

BACKGROUND: Relapses in multiple sclerosis (MS) can cause significant neurologic disability. Natalizumab (Antegren) is a humanized anti-alpha4-integrin antibody that inhibits the trafficking of leukocytes across endothelium by blocking binding of alpha4beta1-integrin to vascular cell adhesion molecule-1. OBJECTIVE: To assess the effects of a single dose of IV natalizumab administered soon after the onset of MS relapses. METHODS: In this randomized, double-blind, multicenter trial, the effects of a single dose of IV natalizumab administered soon after the onset of MS relapses were assessed. MS patients (n = 180) in acute relapse were randomly assigned to receive a single dose of natalizumab 1 or 3 mg/kg or placebo and were followed for 14 weeks. RESULTS: There was no difference in Expanded Disability Status Scale (EDSS) score change over time between treatment and placebo groups. In all three groups, approximately half of patients showed EDSS improvement after 2 weeks, rising to 67% by 8 weeks. EDSS improved by a mean value of 0.8 point at week 1, 1.2 points at week 4, and 1.6 points at week 8 in the natalizumab group compared with EDSS improvement of 1.0 point at week 1, 1.6 points at week 4, and 1.6 points at week 8 in the placebo group. A significant decrease in Gd-enhancing lesion volume was seen in both active treatment groups at weeks 1 and 3 compared with placebo. CONCLUSIONS: A single dose of IV natalizumab did not hasten clinical recovery after relapse, although a significant decrease in Gd-enhancing lesion volume was observed at 1 and 3 weeks after treatment. These MRI findings are consistent with prior studies of natalizumab and support its further investigation as an agent for the treatment of MS.

Impaired renal function in progressive multiple sclerosis.

The authors analyzed renal function in 25 patients with progressive MS. The mean glomerular filtration rate (GFR) was 92 mL/min/1.73 m(2), compared to the predicted GFR of 110 (p < 0.001). Nine of the 25 (36%) patients had abnormally low GFR (<90). The mean serum creatinine for patients with MS was lower than predicted normal values and poorly estimated GFR using standard equations. These data document impaired renal function in patients with progressive MS and have implications for treatment of these patients with potentially nephrotoxic drugs.

Postmenopausal tubo-ovarian abscess due to Pseudomonas aeruginosa in a renal transplant patient: a case report and review of the literature.

BACKGROUND: Pseudomonas aeruginosa is an uncommon cause of infection in the female genital tract. We report a case of postmenopausal tubo-ovarian abscess (TOA) due to P. aeruginosa in a renal transplant recipient. The presentation included mild abdominal symptoms with rapid progression of peritonitis and surgical abscess drainage. This is the first such case in an organ transplant recipient described in the English literature. METHODS AND RESULTS: Published reports of 1040 cases of TOA were reviewed. The most common features were a history of sexually transmitted disease or pelvic inflammatory disease, and symptoms including abdominal pain and fever. Escherichia coli, Bacteroides spp., and Klebsiella pneumoniae were the most frequently encountered pathogens. Neisseria gonorrhoeae and Chlamydia trachomatis, which are frequently isolated from cervical cultures, are uncommonly isolated from tubo-ovarian abscesses. Forty percent of patients were treated with antibiotics alone, 18.8% with abdominal surgery, and 32% with surgery and antimicrobial therapy. CONCLUSION: This report illustrates the muted presentation and atypical microbiology of gynecologic infection in an organ transplant recipient.

A Phase I-II study of 96-hour infusional topotecan and paclitaxel for patients with recurrent Müllerian tumors.

BACKGROUND: Topotecan and paclitaxel are schedule dependent chemotherapeutic agents with activity against ovarian carcinoma. A Phase I-II study in which both drugs were administered concurrently by 96-hour, continuous, intravenous infusion was performed to determine the maximum tolerated dose (MTD), toxicities, pharmacokinetics, and efficacy of the combination. METHODS: Women with ovarian or primary peritoneal carcinoma and documented recurrent disease were eligible for the study. The dose of topotecan was escalated from 1.6 mg/m(2) while maintaining the paclitaxel dose constant at 100 mg/m(2). Plasma concentrations of both drugs were monitored daily during the first cycle of therapy. RESULTS: Forty-five patients with a median age of 54 years (range, 42-70 years) received 181 cycles of therapy. Five patients were recruited to each of four dose levels (topotecan 1.6 mg/m(2), 2.0 mg/m(2), 2.8 mg/m(2), and 3.6 mg/m(2)), and an additional 25 patients were treated at the MTD (Phase II). Neutropenia and thrombocytopenia became dose limiting toxicities (DLT) at the fourth dose level. Emesis, mucositis, peripheral neuropathy, diarrhea, and alopecia were mild. Twenty patients (44%) had line-related occlusion, thrombosis, or infection. The mean values (+/- standard deviation) of the apparent steady-state plasma concentrations at the Phase II doses were 2.3 nM +/- 0.5 nM for topotecan lactone, 5.6 nM +/- 2.1 nM for total topotecan, and 40.1 nM +/- 16.8 nM for paclitaxel. There were seven partial responses (Phase II) contributing to an objective response rate of 28% and a median survival time of 11.7 months (range, 0.6-20.1 months). CONCLUSIONS: Topotecan at a dose of 2.8 mg/m(2) and paclitaxel at a dose of 100 mg/m(2) administered by concurrent, 96-hour, continuous intravenous infusions shows activity against tumors of Müllerian origin.

The clinical utility of liposomal doxorubicin in recurrent ovarian cancer.

OBJECTIVES: The aim of this study was to determine the efficacy and toxicity of single agent off-protocol, liposomal doxorubicin (Doxil Alza), in consecutive patients with recurrent ovarian cancer and to investigate the influence of HER-2/neu expression on response to liposomal doxorubicin. PATIENTS AND METHODS: Retrospective analysis of 72 consecutive patients treated, typically with liposomal doxorubicin 40 mg/m(2) q28 days between January 1997 and December 1998. Results. Twenty-nine patients (40%) had platinum- and taxane-resistant tumors. Nineteen patients (27%) responded with clinical or radiological evidence of response with reduction in CA-125 of >50%. One complete response (CR) and 7 partial responses (PRs) occurred in platinum- and taxane-resistant patients (radiological response (RR) 29%) and 8 PRs occurred in patients with visceral metastases (RR 28%). Time to progression was 5.3 (2.1-12.1) months. Only 7 dose delays (3%) and 20 dose reductions (8%) were necessary in 265 cycles of treatment. Hematological toxicity was generally mild with grade (Gr) > or =III neutropenia in 1 (2%), Gr > or =III thrombocytopenia in 1 (1%), and Gr > or =III anemia in 8 patients (11%). One patient (1%) was admitted with fever and neutropenia. Other toxicity was minimal with Gr > or =III mucositis occurring in 3 patients (4%). Gr > or =III cutaneous toxicity was seen in 6 patients (8%). Three patients (4%) had a >10% fall in ejection fraction but there was no unequivocal clinical heart failure. CONCLUSIONS: The data suggest that liposomal doxorubicin is an active drug in both taxane- and platinum-sensitive and resistant recurrent ovarian cancer. Liposomal doxorubicin is associated with tolerable toxicity and is particularly well tolerated in patients with multiple prior lines of treatment.

Prospective randomized comparison of dacarbazine (DTIC) versus DTIC plus interferon-alpha (IFN-alpha) in metastatic melanoma.

Dacarbazine (DTIC) has been the mainstay of chemotherapy for metastatic melanoma for over two decades, but only 15%-20% of patients respond and benefit is usually transient. Randomized studies combining DTIC with interferon-alpha (IFN-alpha) in advanced disease have so far been inconclusive in terms of response and survival. We report a randomized prospective pilot Phase III trial of DTIC +IFN-alpha in patients with metastatic melanoma. The primary endpoint was death. A total of 61 patients were randomized between April 1995 and April 1998. Differences in survival between groups were assessed using log-rank analysis. Quality of life was measured using the European Organization for Research on Treatment of Cancer QLQ C30 (+3) questionnaire. Fifty-seven patients died during the study. The median survival for patients receiving DTIC was 7.2 months (95% confidence interval (CI) 4.4-9.0); it was 4.8 months for DTIC + IFN-alpha (95% CI 2.0-8.0). There was no significant difference in survival between the two treatment arms (chi2 unadjusted = 0.15, P = 0.70; chi2 adjusted = 0.01, P = 0.91). The 6-month survival of those patients randomized to DTIC alone was 58% compared with 40% for those patients randomized to DTIC + IFN-alpha. There were no differences in quality of life between treatment groups. This study failed to demonstrate a survival benefit for patients receiving IFN-alpha in combination with DTIC. These results are inconclusive primarily owing to the small size of the trial. A meta-analysis is required to determine whether there is a role for the addition of IFN-alpha to DTIC in the treatment of this disease.

Partnering with communities to improve health: the New York City Turning Point experience.

Concurrent with the New York City Department of Health's reorganization efforts, the Robert Wood Johnson and W.K. Kellogg Foundations launched Turning Point, a national initiative designed to strengthen the nation's public health system. The Turning Point initiative has emphasized broad-based partnership building and planning as key prerequisites for improving public health practice. In response to the foundations' request for proposals, the department formed a New York City Public Health Partnership, which in turn applied for and was granted a Turning Point planning grant. This funding allowed New York City Turning Point to initiate a public health planning process, part of which involved convening forums in each of the five boroughs. With over 1,100 community participants, these forums provided both a starting point for establishing public health priorities and an interactive setting for sharing health and demographic data. Included among the issues that emerged as priorities were: access to care, environmental health, mental health, housing, asthma, education, and dietary issues. Building on the forum outcomes, the New York City Public Health Partnership developed a public health system improvement plan. The goals delineated in this plan are: (1) to create and support public health partnerships at the community, borough, and citywide levels; (2) to identify community health concerns and develop strategies responsive to these concerns; and (3) to develop policies to support and sustain a community health approach to improve health status. This article also discusses possible roles for local health departments in promoting a community health approach to address public health concerns.

Mechanical load increases muscle IGF-I and androgen receptor mRNA concentrations in humans.

The mechanism(s) of load-induced muscle hypertrophy is as yet unclear, but increasing evidence suggests a role for locally expressed insulin-like growth factor I (IGF-I). We investigated the effects of concentric (CON) vs. eccentric (ECC) loading on muscle IGF-I mRNA concentration. We hypothesized a greater IGF-I response after ECC compared with CON. Ten healthy subjects (24.4 +/- 0.7 yr, 174.5 +/- 2.6 cm, 70.9 +/- 4.3 kg) completed eight sets of eight CON or ECC squats separated by 6-10 days. IGF-I, IGF binding protein-4 (IGFBP-4), and androgen receptor (AR) mRNA concentrations were determined in vastus lateralis muscle by RT-PCR before and 48 h after ECC and CON. Serum total testosterone (TT) and IGF-I were measured serially across 48 h, and serum creatine kinase activity (CK), isometric maximum voluntary contraction (MVC), and soreness were determined at 48 h. IGF-I mRNA concentration increased 62% and IGFBP-4 mRNA concentration decreased 57% after ECC (P < 0.05). Changes after CON were similar but not significant (P = 0.06-0.12). AR mRNA concentration increased (P < 0.05) after ECC (63%) and CON (102%). Serum TT and IGF-I showed little change. MVC fell 10% and CK rose 183% after ECC (P < 0.05). Perceived soreness was higher (P < 0.01) after ECC compared with CON. Results indicate that a single bout of mechanical loading in humans alters activity of the muscle IGF-I system, and the enhanced response to ECC suggests that IGF-I may somehow modulate tissue regeneration after mechanical damage.

The HRAS1 minisatellite locus and risk of ovarian cancer.

Approximately 10% of ovarian cancers are due to mutations in highly penetrant inherited cancer susceptibility genes. The highly polymorphic HRAS1 minisatellite locus, located just downstream from the proto-oncogene H-ras-1 on chromosome 11p, consists of four common progenitor alleles and several dozen rare alleles, which apparently derive from mutations of the progenitors. Mutant alleles of this locus represent a major risk factor for cancers of the breast, colorectum, and bladder, and it was found that BRCAI mutation carriers with at least one rare HRAS1 allele have a greater risk of ovarian cancer than BRCA1 carriers with only common HRAS1 alleles. There are no conclusive studies of HRAS1 alleles in sporadic epithelial ovarian cancer. A case-control study of HRAS1 alleles was performed on DNA from 136 Caucasian patients with ovarian cancer and 108 cancer-free controls using conventional (Southern blot) and PCR-based methods to determine the frequency of rare HRAS1 alleles. Odds ratios (ORs) were estimated using unconditional logistic regression methods. A single degree of freedom test was used to assess the significance of linear trend across categories of increasing exposure. A statistically significant association between rare HRAS1 alleles and risk of ovarian cancer was observed [OR, 1.70; 95% confidence interval (CI), 1.03-2.80; P = 0.04]. Having only one rare allele was associated with a relative risk of 1.66 (95% CI, 0.91-3.01), whereas having two rare alleles increased the relative risk to 2.86 (95% CI, 0.75-10.94; trend P = 0.03). Analysis of HRAS1 allele types by the age of the case at diagnosis revealed that younger cases (<45 years) had a borderline statistically significant increased association with rare HRAS1 alleles compared to older cases (> or = 0 years; OR, 1.89; 95% CI, 0.90-3.98; P = 0.09). Rare HRAS1 alleles contribute to ovarian cancer predisposition in the general population. Thus, the HRAS1-variable number of tandem repeats locus may function as a modifier of ovarian cancer risk in both sporadic and hereditary ovarian cancer.

Efficacy and hematologic toxicity of salvage chemotherapy following stem cell-supported high-dose chemotherapy in women with recurrent ovarian cancer.

OBJECTIVE: The objective of this study was to determine the efficacy and hematologic toxicity of salvage chemotherapy in patients with recurrent ovarian cancer following high-dose chemotherapy and peripheral blood stem cell transplantation (PBSCT). METHODS: A retrospective analysis of 19 Massachusetts General Hospital case records of women with relapsed ovarian cancer following PBSCT was conducted. RESULTS: Between February 1996 and September 1998, 24 women with ovarian cancer were treated with PBSCT. Nine patients were treated with an upfront PBSCT regimen to consolidate first-line chemotherapy and 15 patients were treated with PBSCT after a median of two lines (range: 1-3) of prior chemotherapy. Sixteen patients presented with relapsed disease at a median of 230 days post-PBSCT and 3 patients had persistent disease through high-dose chemotherapy. Each of these 19 patients has been treated with salvage chemotherapy following PBSCT. Patients received one of six different first-line salvage chemotherapy regimens. Sixteen of nineteen patients are alive a median of 383 days (range: 156-868) after relapse following PBSCT. Three patients died of progressive disease at a median of 284 days (range: 224-648) after post-PBSCT relapse. Six patients achieved a complete response, four patients had a partial response, three patients had stable disease, and six patients had progressive disease in response to first-line salvage chemotherapy. Seven patients experienced grade III/IV neutropenia, and three patients experienced grade III/IV thrombocytopenia. CONCLUSIONS: We conclude that in a patient population selected for chemotherapy sensitive and low-volume disease prior to PBSCT, patients with recurrent tumor appear to respond to salvage chemotherapy, and associated hematologic toxicity is acceptable and manageable.

Intraoperative radiation therapy in the treatment of pelvic gynecologic malignancies: a review of fifteen cases.

OBJECTIVE: The aim of this study was to review the experience with intraoperative radiation therapy (IORT) in the treatment of gynecologic pelvic malignancies at the Massachusetts General Hospital. METHODS: From July 3, 1996, through July 28, 1999, 15 patients were treated with IORT for gynecologic malignancies in a dedicated IORT operating room suite at the Massachusetts General Hospital. Hospital medical records, radiation oncology records, and office charts were reviewed on all patients treated with IORT. IORT was given in the presence of positive surgical margins and where the doses needed for adjuvant postoperative external beam radiotherapy (EBRT) would exceed those tolerated by normal structures. One patient presented with primary disease and 14 with local or regional recurrence. Follow-up time ranged from 3 to 36 months. RESULTS: Treatment in conjunction with IORT included surgery only (7 patients); preoperative EBRT, preoperative brachytherapy, and surgery (1 patient); preoperative chemotherapy and surgery (2 patients); and surgery and postoperative chemotherapy (5 patients). IORT doses ranged from 10 to 22.5 Gy. At the completion of this review, 4 patients (26.6%) have died, 6 (40%) are alive and free of disease, and 5 (33%) are alive with disease persistence or relapse. Of the 10 patients with gross total resection, 5 are alive and free of disease. Of the 5 women with gross residual disease at the time of IORT, only 1 is alive and free of disease. CONCLUSIONS: The volume of residual disease prior to IORT may be an important prognostic indicator for disease relapse. Both local recurrence and distant metastasis were more common among patients with gross residual disease at the time of IORT. Our institutional experience with IORT further supports the importance of optimal surgical resection.

Borderline tumors of the ovary: correlation of frozen and permanent histopathologic diagnosis.

OBJECTIVE: To evaluate the correlation between the diagnosis of borderline tumor of the ovary by frozen and permanent pathology. METHODS: All pathology reports with diagnoses of borderline tumor of the ovary between 1980 and 1998 at Massachusetts General Hospital were reviewed. Univariate and multivariable logistic regression models were constructed for patient age, tumor size, histology, presence of bilateral or extraovarian disease, and concurrent diagnosis of endometriosis or endosalpingiosis. RESULTS: We reviewed 140 cases. The average age of patients was 52.3 years. Eighty tumors were serous, 47 mucinous, 11 mixed, and two endometrioid. The mean diameter overall was 13.7 cm (range 1-70 cm), 10.2 cm for serous, and 20.1 cm for mucinous. Diagnoses of borderline tumors by frozen and permanent pathology were consistent in 60% of cases. Frozen section interpreted a benign lesion as malignant (overdiagnosed) in 10.7% of cases, and interpreted a malignant lesion as benign (underdiagnosed) in 29.3%. No variable was a significant predicator of overdiagnosis. In univariate analysis, underdiagnosis was more likely for other types of tumors than serous (P <.001), tumors larger than 20 cm (P =.039), and tumors confined to the ovaries (P =. 009). When all variables were included in a multiple regression model, only histology was a significant predictor of underdiagnosis (P =.039). CONCLUSION: Frozen or permanent pathology reports of diagnoses of borderline tumor were consistent 60% of the time, whereas the positive predictive value of borderline by frozen section was 89.3%. Tumors other than serous are more likely to be misinterpreted.

Abnormal genital tract bleeding.

The etiology of abnormal genital tract bleeding encompasses a wide range of disorders that can be secondary to anatomic changes of the female genital tract, infection, endocrinologic disorders, malignancies, and systemic illness. Appropriate workup is guided by age-related differential diagnoses for abnormal bleeding. Modern diagnostic tools can quickly focus the evaluation and allow timely intervention. Most abnormal genital tract bleeding is uterine bleeding, which is one of the most common gynecologic problems that health care providers will face. It accounts for approximately 15% of office visits and 25% of gynecologic operations. Abnormal uterine bleeding in reproductive-age women is defined as bleeding at abnormal or unexpected times or by excessive flow at the time of an expected menses. The average menstrual cycle length and duration of flow is 28 days and 4 days, respectively, with an average blood loss of 35 cc (1). Any bleeding should be considered abnormal in premenarchal girls and in post-menopausal women except for those with predictable withdrawal bleeding taking hormone replacement therapy. This article will review the categories of abnormal genital tract bleeding and the diagnostic tools needed to establish the correct diagnosis. Common clinical cases will be presented to illustrate the presenting symptoms, differential diagnoses, workup, treatment, and long-term follow-up.

Transesophageal echocardiography guided enoxaparin antithrombotic strategy for cardioversion of atrial fibrillation: the ACUTE II pilot study.

BACKGROUND: Patients with atrial fibrillation >2 days' duration for whom immediate cardioversion is desired or required are commonly hospitalized for 4 or more days of antithrombotic therapy with intravenous unfractionated heparin and commencement of oral warfarin. For these early cardioversion patients, self-administered low-molecular-weight heparin (enoxaparin sodium) as "bridge" therapy to warfarin may obviate the need for hospitalization and activated partial thromboplastin time monitoring and thus potentially lower costs and enhance utility. OBJECTIVE: To compare feasibility and safety of a transesophageal echocardiography (TEE)-guided enoxaparin strategy with those of a TEE-guided unfractionated heparin strategy in patients with atrial fibrillation of >2 days' duration undergoing early electrical or chemical cardioversion. DESIGN AND SETTING: This is a randomized, multicenter clinical trial at 11 hospitals in the United States. PATIENTS AND INTERVENTION: Two hundred patients with atrial fibrillation >2 days' duration requiring early chemical or electric cardioversion will be enrolled. TEE-guided intravenous unfractionated heparin bridge therapy will be compared with TEE-guided subcutaneous enoxaparin bridge therapy. OUTCOME MEASURES: Feasibility outcomes are time to hospital discharge, patient quality of life/utility, treatment costs, and sinus rhythm. Safety outcomes are ischemic stroke, transient ischemic attack, systemic embolization, major and minor bleeding, clinical hemodynamic instability, and cardiac and cardioversion-related death for a 5-week period from enrollment. CLINICAL IMPLICATIONS: The results of this pilot study will have important clinical and economic implications for the antithrombotic management of patients with atrial fibrillation undergoing TEE-guided cardioversion.
