Post-chemotherapy arthralgia and arthritis in lung cancer.

OBJECTIVE

Evaluate the characteristics of arthritis, arthralgia and musculoskeletal pain after chemotherapy in patients with lung cancer.

MATERIALS AND METHODS

In this study, we evaluate the characteristics of 17 patients with joint symptoms following receiving chemotherapy for lung cancer. Demographic information of patients including sex, age, time of rheumatologic findings after starting of chemotherapy, time of improvement after starting of medication, and relevant laboratory findings for each patient.

RESULTS

A total of seventeen patients (six women with mean age 41.2 ± 5.2 years and 11 men with mean age 42.5 ± 8.2) that received standard chemotherapy for lung cancer according to stage of disease. Joint symptoms usually began about seven months after the first session of chemotherapy. Patients had an average of two tender joints and 1 hr of morning stiffness. Four patients were positive for anti-nuclear antibody, and none of patient was positive for rheumatoid factor. Non-steroidal anti-inflammatory drugs, disease modifying anti-rheumatic drugs (DMARD), corticosteroids, and venlafaxine were prescribed. Four patients did not show an improvement. Follow-up was available for all patients. 11 patients showed favorable responses, characterized by a significant decrease (more than 50%) in morning stiffness, pain, and tender joint counts after a mean of three months' treatment. Two patients had complete resolution of symptoms and did not required further medications for arthritis, arthralgia or musculoskeletal pain.

CONCLUSION

Chemotherapy-related arthropathy in lung cancer is not uncommon. Early treatment with NSAID, DMARD, and corticosteroids is effective in the majority of patients.
