Patient-reported outcomes of patients with advanced biliary tract cancers receiving gemcitabine plus capecitabine: a multicenter, phase II trial of the Swiss Group for Clinical Cancer Research

PURPOSE: To evaluate the effects of palliative chemotherapy with gemcitabine plus capecitabine (GemCap) on patient-reported outcomes measured using clinical benefit response (CBR) and quality-of-life (QOL) measures in patients with advanced biliary tract cancer. PATIENTS AND METHODS: Patients had to manifest symptoms of advanced biliary tract cancer and have at least one of the following: impaired Karnofsky performance score (60 to 80), average analgesic consumption >or= 10 mg of morphine equivalents per day, and average pain intensity score of >or= 20 mm out of 100 mm. Treatment consisted of oral capecitabine 650 mg/m(2) twice daily on days 1 through 14 plus gemcitabine 1,000 mg/m(2) as a 30-minute infusion on days 1 and 8 every 3 weeks until progression. The primary end point was the number of patients categorized as having a CBR or stable CBR (SCBR) during the first three treatment cycles. RESULTS: Forty-four patients were enrolled (bile duct cancer, n = 36; gallbladder cancers, n = 8). The main grade 3 or 4 adverse events included hematologic toxicity and fatigue. After three cycles, 36% of patients achieved a CBR, and 34% achieved an SCBR. Over the full course of treatment, 57% of patients achieved a CBR, and 18% achieved an SCBR. Improved QOL was observed in patients with a CBR or SCBR. The objective response rate was 25%. Median time to progression and overall survival times were 7.2 months and 13.2 months, respectively. CONCLUSION: Chemotherapy with GemCap is well tolerated and effective and leads to a high CBR rate. Patient-reported outcomes are useful for evaluating the effects of palliative chemotherapy in patients with biliary tract cancer.

[Diagnosis, treatment and follow up of prostata cancer]

Prostate cancer is the most frequent diagnosed malignancy in men with an increasing incidence. In well informed men between the age of 50 and 70 years screening should be offered when requested. Not every newly diagnosed prostate cancer requires immediate treatment. Curative treatment should be offered to men with a minimal life expectancy of 10 years. In men older than 50-75 years, therefore further screening is not necessary due to a lack of a therapeutic consequence. Curative treatment options enclose as the gold standard surgical removal, i.e. open radical prostatectomy with pelvic lymph node dissection, and radio-oncologic treatments, be it percutaneous radiation therapy, brachytherapies or a combination thereof. Palliative treatment options are mainly hormonal treatment (medical or surgical androgen deprivation), local radiation, treatment with bisphosphonates, chemotherapy and surgical desobstruction of the prostate. Regular follow up allows for early detection of recurrences and an active treatment concept.

Delayed gadolinium enhanced MRI of cartilage (dGEMRIC): Molekulare MRT-Bildgebung des Hüftgelenkknorpels [Delayed gadolinium enhanced MRI of cartilage (dGEMRIC): molecular MRI of hip joint cartilage]

Factors such as instability and impingement lead to early cartilage damage and osteoarthritis of the hip joint. The surgical outcome of joint-preserving surgery about the hip joint depends on the preoperative quality of joint cartilage.For in vivo evaluation of cartilage quality, different biochemically sensitive magnetic resonance imaging (MRI) procedures have been tested, some of which have the potential of inducing a paradigm shift in the evaluation and treatment of cartilage damage and early osteoarthritis.Instead of reacting to late sequelae in a palliative way, physicians could assess cartilage damage early on, and the treatment intensity could be adequate and based on the disease stage. Furthermore, the efficiency of different therapeutic interventions could be evaluated and monitored.This article reviews the recent application of delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and discusses its use for assessing cartilage quality in the hip joint. dGEMRIC is more sensitive to early cartilage changes in osteoarthritis than are radiographic measures and might be a helpful tool for assessing cartilage quality.

Loss of inhibition over master pathways of bone mass regulation results in osteosclerotic bone metastases in prostate cancer

Prostate cancer is the most common cancer among men in industrialised countries. Most patients with prostate cancer, however, will not die of it. As a result, many of them will experience symptomatic metastasis during the course of the disease. Prostate cancer has a high propensity to metastasize to bone. Unlike many other cancers prostate cancer cells induce a rather osteosclerotic than osteolytic reaction in the bone marrow by interfering with physiological bone remodelling. A proper understanding of the mechanisms of tumour cell-induced bone alterations and exaggerated bone deposition in prostate cancer may open new and urgently needed therapeutic approaches in the field of palliative care for affected patients. In this review we focus on the central role of two major regulators of bone mass, the wingless type integration site family members (WNTs) and the bone morphogenetic proteins (BMPs), in the development of osteosclerotic bone metastases.

Octreotide treatment of patients with hepatocellular carcinoma--a retrospective single centre controlled study

BACKGROUND: Studies of treatment with octreotide of patients with hepatocellular carcinoma (HCC) gave conflicting results. We analyzed retrospectively the survival of our patients treated with octreotide monotherapy and compared it to stage-matched patients who received either TACE, multimodal therapy or palliative care. METHODS: 95 patients seen at the department of Gastroenterology and Hepatology, Medical University of Vienna with HCC in BCLC stage A or B, who received either TACE, multimodal therapy, long-acting octreotide or palliative care were reviewed for this retrospective study. RESULTS: Survival rates of patients with BCLC stage B and any "active" treatment (long-acting octreotide, TACE or multimodal therapy) were significantly higher (22.4, 22.0, 35.5 months) compared to patients who received palliative care only (2.9 months). Survival rates of patients with BCLC stage A and "active" treatment (31.4, 37.3, 40.2 months) compared to patients who received only palliative care (15.1 months) did not show statistically significant differences. Octreotide monotherapy showed a similar outcome compared to patients who received TACE or multimodal therapy. CONCLUSION: Survival under octreotide treatment was not different compared to TACE or multimodal therapy and might be a therapeutic option for patients with HCC.

ESPEN Guidelines on Parenteral Nutrition: geriatrics

Older subjects are at increased risk of partial or complete loss of independence due to acute and/or chronic disease and often of concomitant protein caloric malnutrition. Nutritional care and support should be an indispensable part of their management. Enteral nutrition is always the first choice for nutrition support. However, when patients cannot meet their nutritional requirements adequately via the enteral route, parenteral nutrition (PN) is indicated. PN is a safe and effective therapeutic procedure and age per se is not a reason to exclude patients from this treatment. The use of PN should always be balanced against a realistic chance of improvement in the general condition of the patient. Lower glucose tolerance, electrolyte and micronutrient deficiencies and lower fluid tolerance should be assumed in older patients treated by PN. Parenteral nutrition can be administered either via peripheral or central veins. Subcutaneous administration is also a possible solution for basic hydration of moderately dehydrated subjects. In the terminal, demented or dying patient the use of PN or hydration should only be given in accordance with other palliative treatments.

Recurrence due to neoplastic seeding in head and neck cancer: report of two cases and review of the literature

AIMS AND BACKGROUND Tumor progression due to seeding of tumor cells after definitive treatment for squamous cell carcinomas of the head and neck is an uncommon condition that can considerably worsen the outcome of patients with head and neck cancer. METHODS AND STUDY DESIGN We report two cases of recurrence due to neoplastic seeding from oropharyngeal and oral cancer, respectively. We performed a literature review with MEDLINE as the main search engine. RESULTS Seeding was found to occur most often in tracheotomy scars and gastrostomy sites. The oral cavity, hypopharynx and oropharynx were the primary sites in most cases, and advanced tumor stage seemed to be a risk factor for seeding. Treatment options include salvage surgery, which requires thorough resections, radiotherapy when possible, and palliative management. The prognosis of such events is poor. CONCLUSION Although neoplastic seeding is a well-known phenomenon in cancer surgery, many questions remain unanswered, especially regarding preventive measures and management strategies.

Association between hospice care and psychological outcomes in Alzheimer's spousal caregivers.

CONTEXT Dementia care giving can lead to increased stress, physical and psychosocial morbidity, and mortality. Anecdotal evidence suggests that hospice care provided to people with dementia and their caregivers may buffer caregivers from some of the adverse outcomes associated with family caregiving in Alzheimer's Disease (AD). OBJECTIVES This pilot study examined psychological and physical outcomes among 32 spousal caregivers of patients with AD. It was hypothesized that caregivers who utilized hospice services would demonstrate better outcomes after the death of their spouse than caregivers who did not utilize hospice. METHODS The charts of all spousal caregivers enrolled in a larger longitudinal study from 2001 to 2006 (N=120) were reviewed, and participants whose spouse had died were identified. Of these, those who received hospice care (n=10) were compared to those who did not (n=22) for various physiological and psychological measures of stress, both before and after the death of the care recipient. An Analysis of Covariance (ANCOVA), with postdeath scores as the dependent variable and pre-death scores as covariates, was used for all variables. RESULTS Significant group differences were found in postdeath depressive symptoms (HAM-D; F(1,29)=6.10, p<0.05) and anxiety symptoms (HAM-A; F(1,29)=5.71, p<0.05). Most psychological outcome variables demonstrated moderate effect sizes with a Cohen's d of>0.5 between groups. CONCLUSIONS These data suggest that hospice enrollment may ameliorate the detrimental psychological effects in caregivers who have lost a spouse with Alzheimer's Disease. Based on these pilot data, further prospective investigation is warranted.

A RANDOMIZED TRIAL OF BILEVEL POSITIVE AIRWAY PRESSURE DEVICE AND HIGH FLOW OXYGEN FOR PERSISTENT DYSPNEA IN

Background: Dyspnea is a common and distressing symptom among patients with advanced cancer. The role of bilevel positive airway pressure (BIPAP) and Vapotherm in the relief of dyspnea have not been well defined. We aimed to determine and to compare the efficacy of BIPAP and VapoTherm for cancer related dyspnea. Methods: In this randomized, open-label, crossover study, we randomly assigned advanced cancer patients with persistent dyspnea >=3/10 to either Vapotherm for 2 hours followed by BiPAP for 2 hours, or BiPAP followed by Vaptherm. A variable washout period was instituted between interventions. The primary end point was change in numeric rating scale before and after each intervention. We planned to enroll 50 patients in total. Results: Among the 803 patients screened over the last 8 months, 62 (26%) were eligible, and 16 (2%) were enrolled so far. Five patients completed the entire study successfully, 4 discontinued the study prematurely due to prolonged relief of dyspnea, and 7 dropped out for various reasons, including inability to tolerate BiPAP (N=3), anxiety (N=2), fatigue (N=1) and pain requiring opioids (N=1). The median baseline numeric rating score for dyspnea was 7/10 (interquartile range (IQR) 5-8), and the median baseline Borg score was 4/10 (3-7). Interim analysis revealed that BiPAP was associated with a median change in numeric rating score of -3 (N=10, IQR -6.3 to -1, p=0.007) and modified Borg score of -1 (N=10, IQR -3 to 0.3, p=0.058), while Vapotherm was associated with a median change in numeric rating score of -2 (N=9, IQR -3 to -1, p=0.011) and modified Borg score of -2.5 (N=8, IQR -5.5 to -0.1, p=0.051). Among the 5 individuals who completed the entire study, 2 preferred Vapotherm, 2 favored BiPAP, and 1 liked both. The respiratory rate decreased and the oxygen saturation improved with both interventions. No significant toxicities were observed. Conclusions: We were successfully able to enroll patients onto this clinic trial. Our preliminary results suggest that BiPAP and Vapotherm are highly efficacious in providing relief for patients with persistent refractory dyspnea. A direct comparison of the two interventions will be done upon study completion. Further research is necessary to confirm our findings.

Targeted Multistage Delivery of Nanoparticles to the Bone Marrow

Bone marrow is a target organ site involved in multiple diseases including myeloproliferative disorders and hematologic malignancies and metastases from breast and prostate. Most of these diseases are characterized with poor quality of life, and the treatment options are only palliative due to lack of delivery mechanisms for systemically injected drugs which results in dose limitation to protect the healthy hematopoietic cells. Therefore, there is a critical need to develop effective therapeutic strategies that allow for selective delivery of therapeutic payload to the bone marrow. Nanotechnology-based drug delivery systems provide the opportunity to deliver drugs to the target tissue while decreasing exposure to normal tissues. E-selectin is constitutively expressed on the bone marrow vasculature, but almost absent in normal vessels, and therefore, E-selectin targeted drug delivery presents an ideal strategy for the delivery of therapeutic nanoparticles to the bone marrow. The objective of this study was to develop a novel bone marrow targeted multistage vector (MSV) via E-selectin for delivery of therapeutics and imaging agents. To achieve this goal, Firstly, an E-selectin thioaptamer (ESTA) ligand was identified through a two-step screening from a combinatorial thioaptamer library. Next, ESTA-conjugated MSV (ESTA-MSV) were developed and evaluated for their stability and binding to E-selectin expressing endothelial cells. Different types of nanoparticles including liposomes, quantum dots, and iron oxide nanoparticles were loaded into the porous structure of ESTA-MSV. In vivo targeting experiments demonstrated 8-fold higher accumulation of ESTA-MSV in the mouse bone marrow as compared to non-targeted MSV Furthermore, intravenous injection of liposomes loaded ESTA-MSV resulted in a significantly higher accumulation of liposome in the bone marrow space as compared to injection of non-targeted MSV or liposomes alone. Overall this study provides first evidence that E-selectin targeted multistage vector preferentially targets to bone marrow vasculature and delivers larger amounts of nanoparticles. This delivery strategy holds potential for the selective delivery of large amounts of therapeutic payload to the vascular niches in the bone marrow for the treatment of bone marrow associated diseases.

A quality of life subscale for terminally ill cancer patients

A subscale was developed to assess the quality of life of cancer patients with a life expectancy of six months or less. Phase I of this study identified the major concerns of 74 terminally ill cancer patients (19 with breast cancer, 19 with lung cancer, 18 with colorectal cancer, 9 with renal cell cancer, 9 with prostate cancer), 39 family caregivers, and 20 health care professionals. Patients interviewed were being treated at the University of Texas M. D. Anderson Cancer Center or at the Hospice at the Texas Medical Center in Houston. In Phase II, 120 patients (30 with breast cancer, 30 with lung cancer, 30 with colorectal cancer, 15 with prostate cancer, and 15 with renal cell cancer) rated the importance of these concerns for quality of life. Items retained for the subscale were rated as "extremely important" or "very important" by at least 60% of the sample and were reported as being applicable by at least two-thirds of the sample. The 61 concerns that were identified were formatted as a questionnaire for Phase III. In Phase III, 356 patients (89 with breast cancer, 88 with lung cancer, 88 with colorectal cancer, 44 with prostate cancer, and 47 with renal cell cancer) were interviewed to determine the subscale's reliability and sensitivity to change in clinical status. Both factor analysis and item response theory supported the inclusion of the same 35 items for the subscale. Internal consistency reliability was moderate to high for the subscale's domains: spiritual (0.87), existential (0.76), medical care (0.68), symptoms (0.67), social/family (0.66), and emotional (0.61). Test-retest correlation coefficients also were high for the domains: social/family (0.86), emotional (0.83), medical care (0.83), spiritual (0.75), existential (0.75), and symptoms (0.81).^ In addition, concurrent validity was supported by the high correlation between the subscale's symptom domain and symptom items from the European Organization for Research and Treatment of Cancer (EORTC) scale (r = 0.74). Patients' functional status was assessed with the Eastern Cooperative Oncology Group (ECOG) Performance status rating. When ECOG categories were compared to subscale domains, patients who scored lower in functional status had lower scores in the spiritual, existential, social/family, and emotional domains. Patients who scored lower in physical well-being had higher scores in the symptom domain. Patient scores in the medical care domain were similar for each ECOG category. The results of this study support the subscale's use in assessing quality of life and the outcomes of palliative treatment for cancer patients in their last six months of life. ^

Trastuzumab treatment beyond progression in advanced breast cancer: patterns of care in six Swiss breast cancer centers.

BACKGROUND Trastuzumab is an established treatment for HER2-positive breast cancer (BC). We analyzed Swiss patterns of care in patients with HER2-positive BC after disease progression on trastuzumab-containing therapy for metastatic BC (MBC). PATIENTS AND METHODS A retrospective analysis was performed in six Swiss BC centers. Patients with HER2-positive MBC treated with at least one infusion of trastuzumab for advanced disease between January 2006 and December 2007 were identified. Treatment patterns in first and further lines were analyzed. RESULTS All of the 72 identified patients received trastuzumab as their first palliative anti-HER2 therapy, either as monotherapy (n = 23) or in combination with chemotherapy (typically taxane or vinorelbine; n = 49). Median time to progression was 8.1, 8.0 and 7.9 months in the monotherapy, trastuzumab-taxane and trastuzumab-vinorelbine cohorts, respectively. After progression on first-line anti-HER2 therapy, trastuzumab was continued in 67 of 68 patients who received further therapy. One patient received second-line lapatinib plus capecitabine. The median duration of anti-HER2 therapy was 20 months. Patients received a median of 4 lines of anti-HER2 therapy. CONCLUSIONS Durable responses were achieved with repeated exposure to anti-HER2 therapy. In a selected patient population, trastuzumab monotherapy appears to be a reasonable first-line treatment option.

Euthanasia and physician-assisted suicide in amyotrophic lateral sclerosis: a prospective study.

The objective of this study is to determine if quality of care, symptoms of depression, disease characteristics and quality of life of patients with amyotrophic lateral sclerosis (ALS) are related to requesting euthanasia or physician-assisted suicide (EAS) and dying due to EAS. Therefore, 102 ALS patients filled out structured questionnaires every 3 months until death and the results were correlated with EAS. Thirty-one percent of the patients requested EAS, 69 % of whom eventually died as a result of EAS (22 % of all patients). Ten percent died during continuous deep sedation; only one of them had explicitly requested death to be hastened. Of the patients who requested EAS, 86 % considered the health care to be good or excellent, 16 % felt depressed, 45 % experienced loss of dignity and 42 % feared choking. These percentages do not differ from the number of patients who did not explicitly request EAS. The frequency of consultations of professional caregivers and availability of appliances was similar in both groups. Our findings do not support continuous deep sedation being used as a substitute for EAS. In this prospective study, no evidence was found for a relation between EAS and the quality and quantity of care received, quality of life and symptoms of depression in patients with ALS. Our study does not support the notion that unmet palliative care needs are related to EAS.
