Management of cancer pain with analgetic adjuvant and weak opioid in prostate cancer bone metastases: A case series

BACKGROUND: In cancer patients, cancer pain is the most common cancer complication. About 60–90% of patients with advanced stage cancer experience various levels of pain, and about 30% of patients have been suffering from persistent severe pain. Bones are the most frequent targets of metastases in patients with cancer such as breast, prostate, lung, kidney, and thyroid. In advanced prostate cancer, bone metastasis leads to bone pain, skeletal fracture, and increased mortality. At least 75% of patients with bone metastasis experience bone pain. CASE DESCRIPTION: We report three cases of cancer pain, treated with primary cancer from the prostate metastasis to the spine. All three patients had lower back pain that radiated to the left and right limbs, with mixed pain and bone pain, where early hospital admission shows the Numeric Rating Scale (NRS) pain scale 9–10. Treated with administration of adjuvant therapy (Gabapentin) and weak opioids (injections of Tramadol) as well as injections of Metylprednisolone (for 3 days), the patient's pain scale was evaluated, and the average NRS obtained on days 2–4 was 5–6. On day 5–8, treatment continued with Gabapentin and Tramadol injections, and the pain scale (NRS) decreased to 2–3. All patients on the 8-9(th) day of treatment also received Biphosphonates to reduce pain, bone damage, fracture risk, and blood calcium levels. Patients can be discharged with an oral Gabapentin prescription only. CONCLUSION: A pain scale (NRS) reduction of >50% is obtained from the initial pain scale in cancer pain patients treated using a combination of adjuvant therapy and weak opioids.
