IntroductionWith the widespread use of sequential anthracycline/ taxane-based chemotherapy for early-stage breast cancer, clinicians are becoming rapidly aware of toxicities associated with those regimens. Despite the low incidence reported in the literature of significant arthralgia and myalgia with those regimens, it is clinically evident that a substantial proportion of patients develop such toxicities. We performed a pilot study to investigate the extent of this problem. Patients and MethodsPatients who had received prior adjuvant or neoadjuvant chemotherapy [doxorubicin-cyclophosphamide followed by paclitaxel (ac-t), doxorubicincyclophosphamide followed by docetaxel (ac-d), or 5-fluourouracil-epirubicin-cyclophosphamide followed by docetaxel (fec-d)] completed a retrospective outcomes-based survey. The survey utilized the Functional Assessment of Cancer Therapy-Taxane Scale, the Memorial Symptom Assessment Scale, and a modified Brief Pain Inventory. ResultsInterviews were conducted with 82 patients. Interviewees had received ac-t (43%), fec-d (43%), and ac-d (14%). Pain as a side effect of either the anthracycline or the taxane chemotherapy was reported by 87% of patients. Most of the patients (79%) indicated that their worst pain occurred during the taxane component of treatment. Compared with paclitaxel, docetaxel was reported to cause more pain. Narcotics for pain management were required by 35 of 82 patients (43%). ConclusionsA significant number of patients receiving sequential anthracycline/taxane-based chemotherapy for early-stage breast cancer experience pain, particularly during the taxane component. Prospective patientreported outcome assessments are needed to help individualize treatment interventions and to improve symptom management in this population.

BackgroundAn estimated 20%-40% of cancer patients will develop brain metastases. Whole-brain radiotherapy (WBRT) is the standard treatment for patients with brain metastases. Although WBRT can reduce neurologic symptoms, the median survival following WBRT is between 3 and 6 months. Given this limited survival, it is important to consider quality of life (QOL) when treating patients with brain metastases. However, few studies have focused on QOL and improvement in patient-rated symptoms as primary outcomes. ObjectiveFor an accurate measurement of the extent to which previous trials have utilized QOL tools to evaluate the efficacy of WBRT for treatment of brain metastases, we undertook a literature review to examine the common endpoints and QOL instruments used. MethodsWe conducted a systematic search using the MEDLINE (1950( to December 2007 and Cochrane Central Register of Controlled Trials (4th quarter 2007) databases. Eligible studies investigated WBRT in one of the study arms. The following outcomes were included: median survival, overall survival, neurologic function, 1-year local control, and overall response; use of QOL instruments, performance status scales, and neurologic function assessments; and use of other assessment tools. Patient-rated QOL instruments were defined as those that strove to assess all dimensions of QOL; observerrated performance instruments such as the Karnofsky performance status (KPS) were deemed to be performance scales. ResultsWe identified sixty-one trials that included WBRT nine evaluated the treatment of a single brain metastasis, and fifty-two evaluated the treatment of multiple brain metastases. Although fifty-five of the trials employed a QOL instrument, few trials focused on QOL as an outcome. We found 23 different instruments used to evaluate QOL. The most commonly employed instrument was the KPS (n = 33), followed by various neurologic function classification scales (n = 21). A preponderance of the studies used 1 (n = 26, 43%) or 2 (n = 21, 34%) QOL instruments.A total of fourteen published trials on brain metastases included an evaluation of the study population's QOL. Those trials included three that used the Functional Assessment of Cancer Therapy-General scale and Brain subscale instrument, three that used the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (C30) and the Brain Cancer Module 20 instrument, two that used study-designed QOL instruments, one that used the Edmonton Symptom Assessment Scale, two that used the Spitzer Quality of Life index, and three that used the KPS to evaluate QOL. Some trials reported deterioration in QOL after WBRT in patients with poorer prognosis; other trials detected an improvement in QOL after WBRT in patients with better prognosis. ConclusionsTo date, fourteen trials in brain metastases that have included an evaluation of the study population's QOL have been published. Although some studies showed that certain parameters of QOL deteriorate after WBRT, other studies showed that Q...

Approximately 50% of patients with cancer will develop skeletal metastases, which often lead to significant pain. When a patient complains of pain, a bone scan and/or plain x-rays are ordered as investigations. X-rays necessitate a 1-cm diameter mass and 50% bone mineral loss at minimum for detection. Up to 40% of lesions will be unidentified by x-rays, presenting false-negative results. Computed tomography (CT) scans can recognize a bony metastatic lesion up to 6 months earlier than an x-ray. However, plain x-rays can also lead to rare false-positive results. We present a case with a false-positive result in a patient with lung cancer.

Approximately 27% of North American cancer deaths are attributable to cancer of the lung. Many lung cancers are found at an advanced stage, rendering the tumours inoperable and the patients palliative. Common symptoms associated with palliative lung cancer include cough, hemoptysis, and dyspnea, all of which can significantly debilitate and diminish quality of life (qol). In studies of the effects of cancer therapies, the frequent evaluative endpoints are survival and local control; however, it is imperative that clinical trials with palliative patients also have a qol focus when a cure is unattainable. We conducted a literature review to investigate the use of qol instrument tools in trials studying qol or symptom palliation of primary lung cancer or lung metastases through the use of radiotherapy. We identified forty-three studies: nineteen used a qol tool, and twenty-four examined symptom palliation without the use of a qol instrument. The European Organization for Research and Treatment of Cancer (eortc) qlq-C30 survey was the most commonly used qol questionnaire (in thirteen of twenty trials). Of those thirteen studies, eight also incorporated the lung-specific qol survey eortc qlq-LC13 (or the eortc qlq-LC17). A second lung-specific survey, the Functional Assessment of Cancer Therapy–Lung (fact-L) was used in only two of the twenty trials. In total, only ten of forty-three trials (23%) used a lung-specific qol tool, suggesting that qol was of low priority as an endpoint and that measures created for lung cancer patients are underused. We encourage investigators in future trials to include specific qol instruments such as the eortc qlq-LC13 or the fact-L for studies in palliative thoracic radiotherapy because those instruments provide a measure of qol specific to patients with lung cancer or lung metastases.

Purpose: Decisions about systemic treatment of women with metastatic breast cancer are often based on estrogen receptor (ER), progesterone receptor (PgR), and HER2/neu status of the primary tumour. This study prospectively investigated concordance in receptor status between primary tumour and distant metastases at various stages of progression and assessed the impact of any discordance on patient management.Methods: Biopsies of suspected metastatic lesions were obtained from patients and analyzed for ER/PgR and HER2/neu. Receptor status of metastases was compared to the primary tumour. The treating physician completed questionnaires before and after biopsy to determine whether the biopsy result lead to a change in treatment plan.Results: One hundred and sixteen women were enrolled and 102 underwent biopsy. Of these 52 (51%) were newly diagnosed with metastatic disease, 17 (17%) had received one line of metastatic treatment and 35 (34%) had received 2 or more lines of treatment in the metastatic setting. 86/102 (84%) of samples were sufficient analysis; of these 5/86 biopsies (6%) showed benign disease and one biopsy (1%) confirmed a different malignancy (indolent lymphoma). Changes in hormone receptor status were observed in 33%. Among these, ER discordance was seen in 11%, PgR discordance in 27% and discordance in both ER and PgR in 5%. Loss of PgR was the most common change in hormone receptor status (25%). HER2/neu showed 4% discordance. Three patients (3%) gained and one patient (1%) lost HER2/neu expression. Biopsy results led to a change of management in 12% of patients. Patients with newly diagnosed metastatic disease were more likely to show discordance than those previously treated in the metastatic setting. Among triple negative primary tumours, no changes in receptor expression of metastases were seen.Conclusions: This is the largest prospective biopsy study we are aware of. Results demonstrate the presence of substantial discordance in receptor status between primary tumour and metastases. The number needed to biopsy to alter immediate management was 8.5, although biopsy information could also be useful in planning subsequent treatments. Tissue confirmation should therefore, be considered in all patients with suspicion of metastatic recurrence or progression. Citation Information: Cancer Res 2009;69(24 Suppl):Abstract nr 2023.

Prostate cancer is the most common non-skin malignancy in men. Almost all men who die from prostate cancer have hormone-refractory prostate cancer with metastasis to bone. Emerging supportive treatments-including chemotherapy, bisphosphonates, and surgery-require integration that is optimized in a multidisciplinary setting. A multidisciplinary clinic for bone metastases has been in place at Toronto-Sunnybrook Regional Cancer Centre since 1999, combining orthopedic surgery, radiation oncology, interventional radiology, and palliative medicine for all patients with bone metastases. The addition of a prostate-focused multidisciplinary clinic integrates these services for patients with advanced prostate cancer.

Fulvestrant use in pretreated metastatic breast cancer patients is associated with variable response rates. This study aimed to characterize these responses and to develop a prediction model to identify those patients who could potentially derive the most clinical benefit. A nationwide review of patients enrolled in a Canadian compassionate use program from 1999 to 2006 was performed. Prior therapy with tamoxifen, steroidal, and nonsteroidal aromatase inhibitors was mandatory. The dependent variable in the analysis was the proportion of patients requiring chemotherapy at 3 months following the start of fulvestrant. General Linear Mixed modeling was used to identify factors significantly associated with this dependant variable and to subsequently develop the prediction model. Three hundred and five women received at least one dose of fulvestrant; 207 went on to receive chemotherapy (68%). Median duration of fulvestrant treatment was 4.1 months (range 0.8-63.1). Factors predictive of being chemotherapy free at 3 months included older age, no prior adjuvant hormonal therapy, and the absence of lung or brain metastases at the start of therapy. A receiver operating characteristic (ROC) curve analysis had an area under the curve of 0.70 (95% CI 0.60-0.80). This model was able to identify risk information that could be helpful in assessing which patients would most likely benefit from fulvestrant as an intervention with the objective being a delay in chemotherapy.
