Abstract
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.
