Methadone in Cancer-Related Neuropathic Pain: A Narrative Review.

Cancer-related neuropathic pain (CRNP) is often a significant burden on patients' quality of life. There are limited treatment guidelines for cancer-related neuropathic pain outside of CIPN. Although opioids are considered a third-line treatment option, no consensus exists on which opioid is most effective, either as a single agent or in combination with other medications.

Prevention of anastrozole induced bone loss with monthly oral ibandronate: Final 5 year results from the ARIBON trial.

Purpose: The ARIBON trial is a double blind, randomised, placebo controlled study designed to evaluate the impact of ibandronate on bone mineral density (BMD) in women taking anastrozole for adjuvant treatment of breast cancer.

Methods: 131 postmenopausal women with early breast cancer were recruited to the study. Of these, 13 had osteoporosis, 50 osteopenia and 68 normal BMD.

Review of testing and use of adjuvant trastuzumab across a cancer network--are we treating the right patients?

This review of practice assessed all early breast cancer patients diagnosed over 12 months to determine the frequency of human epidermal growth factor receptor 2 (HER2) positivity and trastuzumab use. The frequency of HER2 positivity in routine practice (185/1319; 14%) was less than expected. A significant proportion of patients (56/185; 30%) did not receive trastuzumab, largely due to concerns about chemotherapy tolerability.

Adjuvant trastuzumab in routine clinical practice and the impact of cardiac monitoring guidelines on treatment delivery.

Trastuzumab delivery and changes in left ventricular ejection fraction (LVEF) in 110 patients receiving adjuvant trastuzumab in routine practice are investigated. The potential impact of new, less stringent UK cardiac monitoring guidelines is examined. 86 patients (78%) completed trastuzumab on schedule.

The use of a point of care device for monitoring the bone resorption biomarker urinary N-telopeptide in cancer patients with bone metastases.

Type I collagen is the major constituent of bone and its breakdown products are increasingly used as sensitive markers of bone resorption. The N-terminal peptide-bound crosslinks of type I collagen (NTX) can be measured in urine and is useful for the monitoring of patients with metastatic bone disease. Studies have shown that raised NTX levels in metastatic bone disease correlate with an increased risk of complications and pathological fracture.

Prevention of anastrozole-induced bone loss with monthly oral ibandronate during adjuvant aromatase inhibitor therapy for breast cancer.

Purpose: The aromatase inhibitor anastrozole is a highly effective well-tolerated treatment for postmenopausal endocrine-responsive breast cancer. However, its use is associated with accelerated bone loss and an increase in fracture risk. The ARIBON trial is a double-blind, randomized, placebo-controlled study designed to evaluate the impact of bisphosphonate treatment on bone mineral density (BMD) in women taking anastrozole.

Ten-Year Follow-Up of a Patient with Metastatic Ewing's Sarcoma of the Pelvis.

Patient: We report a 32-year-old women with a pelvic Ewing's sarcoma, who developed skeletal metastases within 20 months of diagnosis but following treatment remains disease-free at 10 years.

Discussion: Ewing's sarcoma is a highly malignant tumour of bone. Presentation of a pelvic tumour over the age of 30 years is extremely rare and associated with a poor prognosis.

Epirubicin/vinorelbine adjuvant chemotherapy in young women with breast cancer is associated with preservation of menstrual function.

Aims: To determine whether the epirubicin and vinorelbine regimen in the adjuvant (neoadjuvant) treatment of breast cancer has minimum adverse effects on menstrual function.

Patients And Methods: Thirty-six premenopausal women with a median age of 32 (25-47) years received epirubicin and vinorelbine. Twenty-eight received only epirubicin and vinorelbine without any other neo/adjuvant chemotherapy agents.

Prolonged efficacy of a single dose of the bisphosphonate zoledronic acid.

Purpose: Bisphosphonates play a central role in the management of bone loss due to a range of disorders, including metastatic bone disease, cancer treatment-induced bone loss, and postmenopausal osteoporosis. With potent bisphosphonates, such as zoledronic acid, it may be possible to maintain efficacy with relatively infrequent administration.

Experimental Design: Sixty-six patients who were osteopenic at >1 year following curative cancer therapy received a single i.

The use of bone markers in a 6-week study to assess the efficacy of oral clodronate in patients with metastatic bone disease.

Biochemical markers of bone metabolism are strongly associated with skeletal complications in metastatic bone disease. The bisphosphonate clodronate reduces skeletal morbidity by inhibiting bone resorption. This study investigated the use of bone markers to assess the efficacy of oral clodronate across a range of clinically relevant doses.

Exemestane in metastatic breast cancer: effective therapy after third-generation non-steroidal aromatase inhibitor failure.

Exemestane is a potent steroidal aromatase inhibitor (AI) with activity in post-menopausal women with metastatic breast cancer, with a reported clinical benefit (CB) rate of 24.3% after prior AI therapy. Data on 114 patients (112 female, 2 male) were obtained retrospectively at two cancer centres.

Bone resorption predicts for skeletal complications in metastatic bone disease.

Relationships between the rate of bone resorption (measured by urinary N-telopeptide (Ntx) excretion) and a range of skeletal complications have been evaluated in patients with metastatic bone disease. A total of 121 patients had monthly measurements of Ntx during treatment with bisphosphonates. All skeletal-related events, plus hospital admissions for bone pain and death during the period of observation, were recorded.

Double-blind, randomised, placebo-controlled, dose-finding study of oral ibandronate in patients with metastatic bone disease.

Background: Bisphosphonates are an important component of the treatment of metastatic bone disease but more potent, oral formulations are required to improve the effectiveness and convenience of treatment. An oral formulation of the new bisphosphonate, ibandronate (BM 21.0955) has recently been developed.

A randomised phase II study of oral pamidronate for the treatment of bone metastases from breast cancer.

47 patients with progressive, painful, predominantly lytic bone metastases from breast cancer were included in a randomised double-blind phase II trial comparing the effects of pamidronate 150 and 300 mg daily. Oral pamidronate produced either sclerosis or stabilisation of lytic metastases for at least 24 weeks in 5 of 24 and 3 of 23 patients at the 300 and 150 mg dose levels, respectively. Evidence of symptomatic improvement was observed in 5 of 22 (23%) and 7 of 22 (32%) patients for symptomatic disease at the respective doses.

Relationships between biochemical and symptomatic response in a double-blind randomised trial of pamidronate for metastatic bone disease.

Purpose: The aim of this study was to evaluate pamidronate for bone pain in a randomised double-blind trial and to evaluate the contribution of new markers of bone resorption in patients with bone metastases.

Patients And Methods: Fifty-two patients with painful bone metastases were randomised to receive a two-hour infusion of pamidronate 120 mg or an identical infusion of saline. Four weeks later, all patients received pamidronate 120 mg.

High dose pamidronate: clinical and biochemical effects in metastatic bone disease.

Eighty-six patients with heavily pretreated progressive bone metastases (52 with breast carcinoma, 17 with prostate carcinoma, and 17 others) were included in 2 studies designed to assess the clinical and biochemical effects of a single 120 mg, 2-hour infusion of pamidronate. No other systemic anticancer treatment or radiotherapy were administered. Pamidronate had a significant beneficial effect, with a reduction in a symptom score measuring pain, World Health Organization performance status, and analgesic consumption and improvement in quality of life when compared with a placebo infusion.

Evaluation of new bone resorption markers in a randomized comparison of pamidronate or clodronate for hypercalcemia of malignancy.

Purpose: To compare the effects of two bisphosphonates on markers of bone resorption in a randomized double-blind trial for the treatment of hypercalcemia of malignancy.

Patients And Methods: Thirty-two patients with a serum calcium (sCa) level > or = 2.7 mmol/L that persisted after 48 hours of saline rehydration were randomized to receive pamidronate 90 mg or clodronate 1,500 mg.

Metabolic effects of pamidronate in patients with metastatic bone disease.

We have evaluated the value of specific bone resorption markers in monitoring metastatic bone disease to define the duration of action of a single high-dose pamidronate infusion. Twenty patients received a single infusion of pamidronate 120 mg for painful bone metastases. Ten out of these 20 patients also received a second infusion.

The future of bisphosphonates in cancer.

Bisphosphonates, in conjunction with rehydration, are now the treatment of choice for hypercalcaemia of malignancy. They can also relieve bone pain and improve quality of life as single agent therapy and, in conjunction with systemic anticancer treatments, can prevent skeletal complications and slow down the metastatic process. The clinical effects are greatest and most clearly defined in breast cancer and multiple myeloma, but, theoretically, clinical benefit should be achievable across the entire spectrum of metastatic bone disease.

A randomised double-blind comparison of intravenous pamidronate and clodronate in the hypercalcaemia of malignancy.

In conjunction with rehydration, the bisphosphonates are the treatment of choice for hypercalcaemia of malignancy. Single infusions of either pamidronate or clodronate are usually effective, but a direct comparison of the two agents given at the highest doses commonly used has not been performed. Forty-one patients (15 breast, 12 squamous carcinomas, four lymphomas, four bladder, two prostate and four others) with hypercalcaemia of malignancy (corrected serum calcium > 2.

High-dose intravenous pamidronate for metastatic bone pain.

The bisphosphonates are able to relieve pain from metastatic bone disease and, when given intravenously, may promote bone healing of lytic metastases. In this study, the aim was to assess the acute effects of a single 'high-dose' intravenous treatment with pamidronate on pain, mobility, analgesic consumption and quality of life (QOL). Thirty-four normocalcaemic patients with painful progressing bone metastases (22 from breast, five prostate and seven others) received a single intravenous infusion of 120 mg of pamidronate as palliative therapy.
