Double-Blind Placebo-Controlled Trial of Adjuvant Pamidronate with Palliative Radiotherapy and Intravenous Doxorubicin for Canine Appendicular Osteosarcoma Bone Pain

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 1 2009
T.M. Fan
Background: Canine osteosarcoma (OSA) causes focal malignant osteolysis leading to severe pain. Despite the documented efficacy of radiotherapy or IV aminobisphosphonates for managing cancer bone pain, their potential combined therapeutic value has not been reported in OSA-bearing dogs. Hypothesis: Pamidronate combined with standardized palliative therapy will improve pain control and bone biologic effects in OSA-bearing dogs. Animals: Fifty dogs with appendicular OSA treated with standardized palliative therapy and either pamidronate or sterile saline. Methods: Randomized, prospective, double-blinded, placebo-controlled study. Treatment responses for dogs receiving standardized palliative therapy with (n = 26) or without (n = 24) adjuvant pamidronate were serially evaluated for changes in subjective pain scores, urine N-telopeptide (NTx) excretion, primary tumor relative bone mineral density (rBMD), and computerized pressure platform gait analysis. Results: Median duration of subjective pain relief for dogs treated with adjuvant pamidronate or placebo was 76 and 75 days, respectively (P= .39). Forty percent (20/50; pamidronate [11/26] and placebo [9/24]) of dogs experienced durable analgesia, defined by pain alleviation ,112 days. For patients achieving durable pain control, dogs treated with pamidronate achieved greater reductions in NTx excretion and larger increases in rBMD compared with placebo controls. Changes in peak vertical force assessed by computerized pressure platform gait analysis correlated with pain alleviation in OSA-bearing dogs. Conclusions and Clinical Importance: Combining pamidronate with standardized palliative therapy is safe, but does not clearly improve pain alleviation. However, in dogs achieving durable pain control, adjuvant pamidronate appears to decrease focal bone resorption in the local tumor microenvironment. [source]


Life-threatening haemorrhage from a sternal metastatic hepatocellular carcinoma

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 6 2000
Chih-Yen Chen
Abstract Rupture of the tumour is a catastrophic complication of hepatocellular carcinoma. The prognosis in patients with a ruptured hepatocellular carcinoma is usually unfavourable. We describe a 46-year-old man who suffered from visible massive tumour haemorrhage due to a hepatitis B-related hepatocellular carcinoma that metastasized to the sternal bone. The prominent tumour mass was bulging over the anterior chest wall on the sternum of the patient, and bled spontaneously. This episode of life-threatening haemorrhage was stopped by surgical ligation of the bleeding site. Palliative radiotherapy shrank the tumour mass size and prevented further possible bleeding. This is likely to be the first reported case with a visible spontaneous tumour bleeding from a sternal metastatic hepatocellular carcinoma. [source]


Utility-adjusted analysis of the cost of palliative radiotherapy for bone metastases

JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2003
Michael B Barton
Summary Palliative radiotherapy is effective in the treatment of bone metastases but is under-utilized, possibly because it is perceived to be expensive. We performed a cost-utility analysis of palliative radiotherapy for bone metastases, evaluating both the actual cost of radiotherapy as well as its impact on quality of life by adjusting for the variation in response to treatment. Hospital records between July 1991 and July 1996 were reviewed to ascertain the number of patients treated with palliative radiotherapy for bone metastases, the average number of fields of radiation delivered to each patient and the average duration of survival. Partial and complete response rates to palliative radiotherapy were obtained from a review of all published randomized controlled trials of radiation treatment of bone metastases. Utility values were assigned to the response rates, and an overall adjusted response rate to radiotherapy was derived. The cost of delivering a field of radiation was calculated. The total cost was divided by the total number of response months to give a utility-adjusted cost per month of palliative radiotherapy. The utility-adjusted cost per month of palliative radiotherapy of bone metastases was found to be AUS$ 100 per month or AUS$ 1200 per utility-adjusted life-year. This study demonstrates that, contrary to popular perception, palliative radiotherapy is a cost-effective treatment modality for bone metastases. [source]


Leptomeningeal carcinomatosis from squamous cell carcinoma of the supraglottic larynx

JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2003
Stephen R Thompson
Summary Leptomeningeal carcinomatosis is an uncommon but devastating form of metastatic spread. To our knowledge, only 16 cases originating from a head and neck cancer have been reported. We describe the first case of a patient with leptomeningeal carcinomatosis arising from a laryngeal squamous cell carcinoma. Shortly after completing treatment for an advanced supraglottic laryngeal cancer, this 63-year-old man presented with lower limb neurological symptoms and signs. Radiological and cytological evidence of leptomeningeal carcinomatosis of the distal spinal canal was identified. He was treated with intrathecal methotrexate and palliative radiotherapy. Although his pain improved, his lower limb weakness worsened. He died 3 weeks after completing radiotherapy. Presumed mode of spread was via the haematogenous route. The natural history and management of leptomeningeal carcinomatosis are discussed. Clinicians should be aware of the uncommon possibility of leptomeningeal carcinomatosis in a patient presenting with an appropriate constellation of symptoms and signs, and a past history of cancer.

Psychological distress and concerns of elderly patients treated with palliative radiotherapy for lung cancer

PSYCHO-ONCOLOGY, Issue 8 2007
N. J. Turner
Abstract We conducted a prospective observational cohort study of 83 elderly patients (aged 75 and above) being treated with palliative radiotherapy for lung cancer, with a comparison group of 49 younger patients (aged 65 and under). Psychological distress and concerns were measured before and after treatment using the Hospital Anxiety and Depression Scale (HADS) and a Concerns Checklist. Psychosocial morbidity was common, however, prevalence was similar in both age groups. There was a trend towards worsening of both anxiety and depression scores after treatment, but this did not reach statistical significance. Younger patients reported more concerns than the older group (median 12 vs 10) but this too was not statistically significant. Concerns about the illness and symptoms were more likely to have been addressed by the care team than were concerns about psychosocial issues such as the family and the future. People of all ages have similar concerns and levels of anxiety and depression whilst receiving palliative radiotherapy for lung cancer. Further research is needed to explore the use of screening tools, like those used in this study, to identify patients' difficulties and target interventions to improve their quality of life.

Sinonasal Undifferentiated Carcinoma: The Search for a Better Outcome,

THE LARYNGOSCOPE, Issue 8 2002
Pierre Y. Musy MD
Abstract Objective To evaluate the clinical outcomes of a standardized treatment approach for sinonasal undifferentiated carcinoma (SNUC). Study Design Single-center, retrospective case series. Methods Fifteen patients with newly diagnosed SNUC were seen in the Department of Otolaryngology-Head and Neck Surgery at the University of Virginia from 1991 to 2000. Long-term follow-up on five additional patients diagnosed between 1986 and 1991 was also analyzed. Results Overall, 10 patients were treated with curative intent with neoadjuvant chemoradiotherapy followed by craniofacial resection (CFR). The majority of the remainder was treated with palliative radiotherapy or chemoradiotherapy alone. Four patients who underwent CFR are currently free of disease at 4, 36, 49, and 164 months postoperatively. The 2-year survival of all evaluable patients, regardless of treatment, was 47%. Two-year survival was 64% in the group treated by CFR and 25% in the group treated with chemo- and/or radiotherapy (P = .076). Conclusion For patients with good performance status and limited intracranial or intraorbital disease, we continue to advocate initial chemoradiotherapy followed by craniofacial resection. Patients who are deemed inoperable as a result of advanced disease may nevertheless experience significant palliation with chemoradiotherapy only. [source]


Is palliative resection of the primary tumour, in the presence of advanced rectal cancer, a safe and useful technique for symptom control?

ANZ JOURNAL OF SURGERY, Issue 4 2004
Nasser Al-Sanea
Introduction: At some time, every general surgeon will be faced with the task of trying to decide what to do with a patient who presents with rectal cancer and unresectable distant metastases. How safe is resectional surgery? What sort of palliation may be expected following resection of the primary tumour? In an attempt to answer these questions, the management and outcomes of all patients with rectal cancer and distant metastases, who were primarily referred to the colorectal unit at King Faisal Specialist Hospital were examined. Methods: All patients who underwent primary surgery for rectal cancer in the presence of metastatic disease were identified. The charts of these patients were examined and their morbidity, mortality and survival were determined. Results: Over an 8-year period 22 patients (average age 54 years) underwent rectal resectional surgery in the presence of metastatic disease. There were 13 men and nine women. The commonest complaint was rectal bleeding. All patients had chest radiographs. Pulmonary metastases were identified in four patients. Nineteen abdominal and pelvic computed tomography scans were performed and eight showed evidence of metastases. Skeletal radiographs in two patients showed evidence of bone metastasis. At operation, intraperitoneal metastases were found in 18 patients. Nine of these were not identified preoperatively. Six patients underwent abdomino-perineal resection, nine anterior resection and seven a Hartmann's procedure. Eight patients developed a significant postoperative complication and one died 42 days after surgery. The mean length of hospital stay was 18.6 days. Nine patients received preoperative radiotherapy. Four patients had palliative radiotherapy, two for bony, one for liver and one for peritoneal metastases. Patients were followed up for a mean of 1.1 years. During follow up, 11 returned to the emergency room on 24 occasions. Two patients required readmission. No patient had further rectal bleeding. The mean survival was 1.3 years. Conclusion: Patients with rectal cancer and unresectable distant metastases can be successfully palliated by resection of the primary tumour with low morbidity and mortality. The early involvement of a palliative care team facilitates patient management and helps patients enjoy what remains of the rest of their lives at home, in comfort and with good symptom control.

Giant basal cell carcinoma masquerading as an osteogenic sarcoma

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2009
Paul Cherian
SUMMARY An 88-year-old man presented to the dermatology outpatient clinic with an 11-month history of a rapidly growing mass overlying a clavicular fracture site. The lesion was 8 × 6 cm, painful, fixed to deeper structures and ulcerated. Superficial and deep biopsies yielded invasive basal cell carcinoma. Imaging demonstrated extensive soft tissue invasion into muscle, bone and potentially into the lung parenchyma. Due to complications arising from subsequent diagnostic procedures, the patient declined further invasive tests. The cutaneous lesion was treated with palliative radiotherapy. We explore the literature regarding the tumorigenic effects of peri-fracture cytokines on the biological behaviour of basal cell neoplasms. [source]
