A case of pulmonary carcinoid in pregnancy and review of carcinoid tumours in pregnancy.

Carcinoid tumours are rare slow growing tumours which arise from primitive neuroendocrine cells. The effect of the pregnant state on carcinoid tumours and vice versa remains unclear, as does the optimal management of carcinoid tumours during the pregnancy including labour. We report the rare case of a 36 year old primigravida woman with large bilateral pulmonary carcinoid tumours. The patient's disease was minimally symptomatic with no clinical suspicion of carcinoid syndrome. Under close observation, the pregnancy progressed well and the patient proceeded to a spontaneous vaginal delivery of a healthy child. We conduct the the first literature review in 30 years of all reported cases in this area and make suggestions as to assessment and monitoring of cases of carcinoid during pregnancy.

Mapping unmet supportive care needs, quality-of-life perceptions and current symptoms in cancer survivors across the Asia-Pacific region: results from the International STEP Study.

Background: To assess the supportive care needs, quality of life (QoL) and symptoms of patients with cancer after the end of first-line treatments and into survivorship in Asian countries using Australian data as benchmark. Patients and methods: A cross-sectional survey was carried out in Australia and eight high-income (HICs) and low-/middle-income (LMICs) Asian countries (China, Japan, Hong Kong SAR, South Korea, Myanmar, Thailand, India, Philippines) using validated scales (Cancer Survivors Unmet Needs scale), physical-symptom concerns (Cancer Survivors Survey of Needs subscale) and a single-item measure of global QoL perception. Results: Data were collected from 1873 patients. QoL was highest in Australia and all other countries had significantly lower QoL than Australia (all P < 0.001). One-quarter of the patients reported low QoL (scores 1-3/10). The most frequently reported symptoms were fatigue (66.6%), loss of strength (61.8%), pain (61.6%), sleep disturbance (60.1%), and weight changes (57.7%), with no difference in symptom experience between Australian data and all other countries, or between HICs and LMICs. Unmet needs of moderate/strong level were particularly high in all aspects assessed, particularly in the area of existential survivorship (psychosocial care) and receiving comprehensive cancer care. Australia and HICs were similar in terms of unmet needs (all low), but LMICs had a significantly higher number of needs both compared with Australia and HICs (all P < 0.001). Conclusion: Health care systems in Asian countries need to re-think and prioritize survivorship cancer care and put action plans in place to overcome some of the challenges surrounding the delivery of optimal supportive cancer care, use available resource-stratified guidelines for supportive care and test efficient and cost-effective models of survivorship care.

An analysis of incidental and symptomatic pulmonary embolism (PE) in medical oncology patients.

AIM: To determine the incidence of symptomatic versus incidental pulmonary embolism (PE) in oncology patients, characterize the nature and extent of incidental PE and the factors contributing to diagnosis. METHODS: Specialized web search engine was used to identify oncology patients with positive imaging studies for PE. PE identified at staging CT scans were classified as incidental PEs, whereas PE diagnosed by CTPA/VQ scan were classified as symptomatic PEs. RESULTS: A total of 111 patients with PE were identified over the period of three years. Of these, 67 (60%) patients had symptomatic whereas 44 (40%) patients had incidental PE. Most PEs were segmental and non-occlusive irrespective of the type of PE or stage of the disease. Incidence of PE was equal with/without chemotherapy. Platinum-based chemotherapy was more commonly associated with PE. Most patients received anticoagulation irrespective of type of PE. CONCLUSION: Forty percent of the diagnosed PEs were incidental, more common in the metastatic group. This may be due to the increased frequency of staging scans performed in patients with metastatic disease, as well as the inherent disease biology of metastatic compared with localized disease. Further prospective analysis of survival by PE subtype and optimal length of anticoagulation in incidental PE is warranted.

Determinants of survival and attempted resection in patients with non-metastatic pancreatic cancer: An Australian population-based study.

BACKGROUND: There are indications that pancreatic cancer survival may differ according to sociodemographic factors, such as residential location. This may be due to differential access to curative resection. Understanding factors associated with the decision to offer a resection might enable strategies to increase the proportion of patients undergoing potentially curative surgery. METHODS: Data were extracted from medical records and cancer registries for patients diagnosed with pancreatic cancer between July 2009 and June 2011, living in one of two Australian states. Among patients clinically staged with non-metastatic disease we examined factors associated with survival using Cox proportional hazards models. To investigate survival differences we examined determinants of: 1) attempted surgical resection overall; 2) whether patients with locally advanced disease were classified as having resectable disease; and 3) attempted resection among those considered resectable. RESULTS: Data were collected for 786 eligible patients. Disease was considered locally advanced for 561 (71%) patients, 510 (65%) were classified as having potentially resectable disease and 365 (72%) of these had an attempted resection. Along with age, comorbidities and tumour stage, increasing remoteness of residence was associated with poorer survival. Remoteness of residence and review by a hepatobiliary surgeon were factors influencing the decision to offer surgery. CONCLUSIONS: This study indicated disparity in survival dependent on patients' residential location and access to a specialist hepatobiliary surgeon. Accurate clinical staging is a critical element in assessing surgical resectability and it is therefore crucial that all patients have access to specialised clinical services.

Hope, optimism and survival in a randomised trial of chemotherapy for metastatic colorectal cancer.

PURPOSE: Psychological responses to cancer are widely believed to affect survival. We investigated associations between hope, optimism, anxiety, depression, health utility and survival in patients starting first-line chemotherapy for metastatic colorectal cancer. METHODS: Four hundred twenty-nine subjects with metastatic colorectal cancer in a randomised controlled trial of chemotherapy completed baseline questionnaires assessing the following: hopefulness, optimism, anxiety and depression and health utility. Hazard ratios (HRs) and P values were calculated with Cox models for overall survival (OS) and progression-free survival (PFS) in univariable and multivariable analyses. RESULTS: Median follow-up was 31 months. Univariable analyses showed that OS was associated negatively with depression (HR 2.04, P < 0.001) and positively with health utility (HR 0.56, P < 0.001) and hopefulness (HR 0.75, P = 0.013). In multivariable analysis, OS was also associated negatively with depression (HR 1.72, P < 0.001) and positively with health utility (HR 0.73, P = 0.014), but not with optimism, anxiety or hopefulness. PFS was not associated with hope, optimism, anxiety or depression in any analyses. CONCLUSIONS: Depression and health utility, but not optimism, hope or anxiety, were associated with survival after controlling for known prognostic factors in patients with advanced colorectal cancer. Further research is required to understand the nature of the relationship between depression and survival. If a causal mechanism is identified, this may lead to interventional possibilities.

Patterns of chemotherapy treatment for women with invasive epithelial ovarian cancer--a population-based study.

OBJECTIVE: Ovarian cancer five-year survival is poor at <40%. In the absence of effective screening or new treatments, ensuring all women receive optimal treatment is one avenue to improve survival. There is little population-based information regarding the primary chemotherapy treatment that women with epithelial ovarian cancer receive. This information is essential to identify potential gaps in care. METHODS: Cancer registries identified all women diagnosed with invasive epithelial ovarian cancer in Australia in 2005 (n=1192). Histopathology, chemotherapy and comorbidity information was abstracted from medical records. Multivariable logistic regression was used to identify factors associated with chemotherapy commencement, regimen, and completion. RESULTS: Women >70 years (p<0.0001), those with high-grade, stage IA/IB cancers (vs. stages IC-IV, p=0.003) and those with mucinous cancers (p=0.0002) were less likely to start chemotherapy. Most treated women received platinum-based drugs (97%), but only 68% received combination carboplatin-paclitaxel and only half completed six cycles without treatment modification/delay. Approximately 19% received single-agent carboplatin: mostly those aged >70 (p<0.0001) and/or with co-morbidities (p<0.0001). Age was the strongest predictor of completing six cycles of combination therapy. CONCLUSIONS: For specific patient groups, particularly older women, there is notable variation from standard treatment. Understanding how treatment variations affect survival and determining optimal regimens for these groups are research priorities.

Phase I trial of CYT997, a novel cytotoxic and vascular-disrupting agent.

BACKGROUND: CYT997 is a novel microtubule inhibitor and vascular-disrupting agent with marked preclinical anti-tumour activity. METHODS: This phase I dose-escalation study assessed the safety, tolerability, pharmacokinetics and pharmacodynamics of CYT997 administered by continuous intravenous infusion over 24 h every 3 weeks to patients with advanced solid tumours. RESULTS: Thirty-one patients received CYT997 over 12 dose levels (7-358 mg m(-2)). Doses up to 202 mg m(-2) were well tolerated. Dose-limiting toxicities were observed at 269 and 358 mg m(-2), consisting of grade 3 prolonged corrected QT interval in two patients and grade 3 hypoxia and grade 4 dyspnea in one patient. All toxicities were reversible. The pharmacokinetics of CYT997 were linear over the entire dose range. Dynamic contrast-enhanced magnetic resonance imaging scans showed significant changes in tumour K(trans) values consistent with vascular disruption in 7 out of 11 evaluable patients treated at CYT997 doses of >or=65 mg m(-2). Moreover, plasma levels of von Willebrand factor and caspase-cleaved cytokeratin-18 increased post-treatment at higher dose levels. Among 22 patients evaluable for response, 18 achieved stable disease for >2 cycles. CONCLUSIONS: CYT997 was well tolerated at doses that were associated with pharmacodynamic evidence of vascular disruption in tumours.

Epithelioid angiosarcoma: Use of angiographic embolisation and radiotherapy to control recurrent haemorrhage.

Epithelioid angiosarcoma is a rare, highly malignant tumour with a poor prognosis. We present the case of a 75 year old man who underwent an incision biopsy to diagnose the soft tissue tumour and suffered from surgically uncontrollable haemorrhage. The case report demonstrates the value of interventional radiology for acute bleeding and radiotherapy for more chronic tumour bleeding.

Phase II study of carboplatin followed by sequential gemcitabine and paclitaxel as first-line treatment for advanced ovarian cancer.

The aim of this exploratory phase II study was to evaluate sequential chemotherapy with carboplatin followed by gemcitabine-paclitaxel combination in chemonaive patients with advanced ovarian cancer. The primary objective was to evaluate time to progressive disease (TTPD); secondary objectives included the evaluation of 1- and 3-year survival, response rates, and toxicity. Following initial debulking surgery or biopsy, patients with FIGO stage IIC-IV disease received four cycles of carboplatin area under the curve (AUC) 6 (day 1) every 21 days, followed by four cycles of gemcitabine 1000 mg/m(2) (days 1 and 8) and paclitaxel 175 mg/m(2) (day 8) every 21 days. A total of 47 patients enrolled, 44 (93.6%) completed the initial four cycles, and 39 patients (82.9%) completed the planned eight cycles. The median and maximum lengths of follow-up were 31.2 and 43.7 months, respectively. Median TTPD was 13.8 months (95% CI, 11.6-21.0 months), and median survival time was 31.2 months (95% CI, 25.2-39.6 months). Survival at 1 and 3 years was 95.7% and 44.2%, respectively. Of the 43 evaluable patients, most (95.3%) of them achieved a CA-125 marker response based on Gynecologic Cancer Intergroup (GCIG) definition. The partial response rate in the seven patients with measurable disease was 46.4%. Myelosuppression was the major toxicity, with grade 3 and 4 neutropenia observed in 76.6% patients and thrombocytopenia in 12.8% patients. The sequential approach of carboplatin followed by gemcitabine-paclitaxel as first-line treatment for patients with ovarian cancer is feasible and well tolerated, and depending upon the findings from other major trials, it may merit further evaluation.

Cisplatin-based therapy: a neurological and neuropsychological review.

The present paper reviews research in the area of the broad-spectrum chemotherapeutic agent cisplatin (cis-diamminedichloro-platinum II) and examines the implications for clinical neuropsychology arising from the neurological disruption associated with cisplatin-based therapy. The paper begins with a brief review of cisplatin treatment in terms other than survival alone, and examines the side-effects and the potential central nervous system (CNS) dysfunction in terms of neurological symptoms and concomitant implications for neuropsychology. Two main implications for clinical neuropsychology arising from cisplatin therapy are identified. First, cisplatin therapy impacts upon the psychological well-being of the patient, particularly during and in the months following treatment. It is suggested that during this time, a primary role for neuropsychology is to focus upon the monitoring and the active enhancement of the patient's social, psychological and spiritual resources. Second, with regard to neurocognitive changes, the review suggests that (1) neurocognitive assessment may not yield stable results within 8 months following treatment and (2) while perceptual, memory, attentional and executive dysfunction may be predicted following cisplatin treatment, little systematic research has been carried out to investigate such a possibility. Future research might profitably address this issue and also specifically examine the effects of low dosage cisplatin-based therapy and the effects of recently developed neuroprotective agents. Finally, there is some evidence to suggest that women may be more susceptible to neurotoxicity during cisplatin therapy, but no gender-related cognitive effects are reported in the cisplatin literature. Future research could usefully investigate gender differences in association with cisplatin chemotherapy.

Detection of colorectal cancer cells in peripheral blood by reverse-transcriptase polymerase chain reaction for cytokeratin 20.

The staging of colorectal cancer currently depends on pathological examination of the surgical specimen and regional lymph nodes, accompanied by imaging tests such as computed tomography (CT) scanning. However, alternative molecular methods to detect circulating tumour cells in blood or bone marrow may provide additional information about the extent of disease and prognosis. We have previously reported the development of a reverse-transcriptase polymerase chain reaction (RT-PCR) for cytokeratin 20 (CK 20) mRNA to detect circulating epithelial tumour cells. In this study, we report on the application of this method for detecting circulating tumour cells in patients with colorectal cancer. Using this method, CK 20 mRNA was detected in 8/8 human colorectal cancer cell lines, in 8/9 biopsies from primary colorectal tumours and in 9/10 biopsies of liver metastasis in patients with metastatic colorectal cancer, suggesting that CK 20 may be a useful target for the detection of circulating tumour cells in this patient group. In spiking experiments, 10 cells were consistently identified in 2 ml of whole blood (1 x 10(6)-1 x 10(7) mononuclear cells). In 12/25 (48%) peripheral blood samples from patients with known metastatic colorectal cancer, CK 20 mRNA was detected. However, there was no correlation between the detection of CK 20 mRNA in the peripheral blood and disease progression and survival in this group of patients. CK 20 mRNA was detected in 1/12 normal blood samples, which raises questions about the absolute specificity of CK 20 expression.

The capitation revolution in health care: implications for the field of nursing.

Health care is being reformed in the United States. However, rather than the reform taking the course of the rejected Clinton health care plan, the invisible hand of the free market is reshaping America's health care sector through the spread of a system known as capitation. This article looks at capitation and its effect on hospitals, which are rapidly adopting this practice. Then it explores the implications for both nurses and nursing administration as hospitals seek to transform themselves into health care delivery systems. It is suggested that hospitals bring nurses and nurse administrators to the forefront on their concerns in setting up such capitated systems.

English-only work rules: balancing fair employment considerations in a multicultural and multilingual healthcare workforce.

Most healthcare organizations are currently or will shortly be composed of a multicultural and multilingual workforce. In attempting to manage such diverse workforces. English-only work rules may be necessary to ensure effective communication among workers. However, care must be taken to insure that the employees' rights to free speech and a harassment-free workplace are not infringed by utilizing English-only work rules. This article attempts to assist the healthcare manager in dealing with the legal aspects of English-only work rules. Specifically, an examination of two legal cases is provided to illustrate the various legal aspects of such work rules. Also, suggestions are offered as to how and when, or when not, to implement English-only work rule in order to avoid possible liability.

Hippocrates takes a blow: the Family and Medical Leave Act and health care administration.

This article examines the special legal and administrative issues for health care management that are posed by the recently enacted Family and Medical Leave Act (FMLA). Following a question-and-answer format, the article outlines the basic provisions of the law and answers what will likely be the most commonly faced administrative questions. It will be seen that FMLA issues and administration will be of significant concern to managers at all levels in health care organizations for some time to come. The conclusion of the article outlines a series of administrative steps that health care managers should undertake to proactively administer the federal leave law.

The right to know and the right to privacy: HIV testing and health care management.

Balancing the rights of suspected or actual HIV-infected individuals versus the preferences of patients, customers, coworkers, and others requires a delicate balancing of individual rights and responsibilities in light of medical and epidemiological facts. It is undoubtedly the quintessential ethical and legal problem of our time for health care management to confront. The dilemmas and the ensuing debate will be intensifying in the nineties as the number of diagnosed AIDS cases and of HIV-positive individuals rapidly expands. Much of the literature in the management field, and unfortunately some in the area of AIDS, consists of writing that ends with such concepts as prescriptions, guidelines, battleplans, etc. for dealing with the problem being discussed. Certainly, excellent articles and books abound in this vein. There is an ever present desire, however, for deductive reasoning whereby, because the topic is management, the problem, whatever it may be, can be managed in the classical scientific method, with one best way to handle the situation. The typical conclusion to an article such as this would be a section subtitled the antithesis of reality, that is, something like "AIDS Made Easy" or "Ten Steps to Effectively Deal with AIDS For Health Care Providers." The foregoing review presents issues that are too complex to be reduced to simplistic action plans for health care management and providers. The legal and ethical problems of the use of HIV testing of health care providers are but one part of the myriad of difficulties brought on by the epidemic--among these being the complex social issues brought on by AIDS and the ramifications in the areas of hospital and health care service reimbursement, cost, capacity, and adequacy. The legal status and propriety of HIV testing will continue to be under debate and in flux for some time, as all available precedent and guidelines in this area are based on current epidemiological and medical knowledge. This is, of course, subject to change and reinterpretation as more is learned about AIDS and as the prevalence of HIV infection, ARC, and AIDS increases. Certainly, it is not an issue that has been resolved by Leckelt and Glover, but these cases have brought more insight into the proper role of HIV testing of health care workers in light of current medical and legal knowledge.(ABSTRACT TRUNCATED AT 400 WORDS)
