Differences in Transplant-Related Complications between Hematologic Malignancies and Solid Tumors Receiving High-Dose Chemotherapy and Autologous Peripheral Blood Stem Cell Transplantation

Pain in the Cancer Survivor

Recent decades have demonstrated significant strides in cancer screening, diagnostics and therapeutics. As such there have been dramatic changes in survival following a diagnosis of cancer.

Drug use evaluation of opioid analgesics in pain management among patients with hematopoietic stem cell transplantation

BACKGROUND

Hematopoietic stem cell transplantation (HSCT) patients usually experience mucositis, musculoskeletal pain associated with high-dose chemotherapy, radiation, post-HSCT infection, or graft-versus-host disease. Pain management is important for the patients' quality of life. We evaluated appropriate opioid analgesic use in HSCT patients to propose effective pain management strategies.

METHODS

A retrospective analysis was conducted using electronic medical records of adult patients with HSCT treated with opioids for moderate to severe pain at Seoul National University Bundang Hospital. The numeric rating scale (NRS) was used in pain management. NRS scores of 4‒10 correspond to moderate to severe pain. Appropriate opioid analgesic use was evaluated following published cancer pain management guidelines.

RESULTS

In total, 119 cases were evaluated, including 369 episodes of moderate to severe pain. Mucositis-related, musculoskeletal, and headache pain occurred in 62.6%, 25.8%, and 6.0% of episodes, respectively. Frequently used opioids were intravenous tramadol (84.9%), fentanyl patch (73.9%), and intravenous morphine sulfate (68.9%). Intravenous and topical administrations were used for mucosal pain. In total, 95.0% of patients received appropriate short-acting opioids for initial pain management, 80.5% received appropriate doses of short-acting opioids, appropriate opioids dose adjustment was done after first assessment in 95.5% of patients, and 85.6% were converted to appropriate long-acting opioids.

CONCLUSION

Short-acting opioid analgesic use for initial pain management and dose adjustment after assessment were appropriate. However, initial and conversion dosages recommended by guidelines may be difficult to implement considering the severity of HSCT patients. Pain management guidelines specific for HSCT patients should be developed in the future.

Determinants of severe oral mucositis in paediatric cancer patients: a prospective study

OBJECTIVE

To analyse the incidence and the determinants of severe oral mucositis (OM) in young cancer patients treated by standard chemotherapy.

METHODS

The study was carried out at the Pediatric Hemato-Oncology unit of Children's Hospital of Rabat. Patients under 16 years of age with malignant disease treated by chemotherapy between January 2001 and December 2006 were recorded.

RESULTS

Consecutive patients (n = 970) with malignant disease were studied. The age ranges from 2 months to 16 years (mean, 6.8 ± 4.1 years). OM occurred in 540 (55.6%) patients, and 17.9% of them encountered severe grades. Mean time to onset of the lesions was 10.5 ± 6.8 (range, 1-22 days) and mean duration was 6.8 ± 3.1 (range, 2-23 days). All chemotherapeutic protocols were associated with OM development (range, 20-100%). Patients with severe OM were more likely to have undifferentiated carcinoma of nasopharyngeal type (RR = 2.6, 95% IC 1.1-6.1), non-Hodgkin lymphoma (RR = 2.1, 95% CI 1.2-2.4) and acute leukaemia (RR = 1.7, 95% CI 1.5-3.6). Methotrexate-based therapies were also associated with the worsening of OM (RR = 1.7, 95% IC 1.2-2.6).

CONCLUSION

Underlying disease and chemotherapy regimens are the principal risk factors of OM development. This model can help in the identification of patients at risk for adequate preventive and therapeutic measures.
