Cancer Pain Management — Safe and Advanced Relief Options
By Alnoor Diagnostic Centre | Shadman, Lahore
Pain Should Not Be an Accepted Part of a Cancer Diagnosis
Among the many burdens that cancer places on patients and their families across Lahore, pain is one of the most feared and one of the most undertreated. Studies consistently show that a significant proportion of cancer patients worldwide experience moderate to severe pain at some stage of their illness — and that a large percentage of them do not receive adequate relief. In Pakistan, where awareness of advanced pain management options remains limited and where cultural attitudes sometimes lead patients to accept pain as inevitable, this treatment gap is even wider.
The reality is that cancer pain can be managed effectively in the vast majority of patients. Modern pain medicine — combining appropriate pharmacological treatment with targeted interventional procedures performed under imaging guidance — provides meaningful relief that genuinely improves quality of life, restores functional capacity, and allows patients to spend their time on what matters rather than on enduring pain.
At Alnoor Diagnostic Centre in Shadman, Lahore, we provide the advanced imaging and interventional radiology services that bring the most effective cancer pain management options directly to patients across the city.
Understanding Cancer Pain — Why It Is Uniquely Complex
Cancer pain differs from most other chronic pain conditions in its complexity and its multiple simultaneous causes. Understanding why it is difficult to manage helps explain why advanced interventional approaches are so important alongside medication.
Tumour-related pain arises directly from the cancer pressing on, invading, or stretching surrounding structures — nerves, bones, organs, and blood vessels. A pancreatic tumour pressing on the coeliac nerve plexus produces severe upper abdominal pain. Bone metastases — cancer that has spread to bone — cause deep, aching bone pain from periosteal nerve stimulation and pathological fracture risk. A tumour compressing a nerve root produces neuropathic radiating pain identical in quality to the radiculopathy of disc herniation but far more difficult to control.
Treatment-related pain adds another layer of complexity. Chemotherapy-induced peripheral neuropathy produces burning and tingling in the hands and feet. Radiation-induced tissue changes cause localised pain that can persist long after treatment ends. Surgical wounds and post-procedural pain require their own management alongside the underlying cancer pain.
Managing this complex, multilayered pain effectively requires both systemic medication adjusted carefully for each patient and targeted interventional procedures that deliver treatment directly to specific pain-generating structures.
The WHO Pain Ladder — The Foundation of Cancer Pain Pharmacology
The World Health Organisation’s analgesic ladder remains the internationally recognised framework for cancer pain medication management. It establishes a stepwise approach — beginning with non-opioid analgesics for mild pain, adding weak opioids for moderate pain, and escalating to strong opioids for severe pain — with adjuvant medications added at each step to address specific pain mechanisms.
For mild cancer pain, paracetamol and NSAIDs provide a foundation. NSAIDs are particularly effective for bone pain from metastases because of their anti-inflammatory mechanism. For moderate pain, tramadol and codeine provide additional analgesic effect. For severe pain, morphine, oxycodone, and fentanyl — delivered orally, transdermally, or intravenously — form the cornerstone of management.
Adjuvant medications address specific pain types. Corticosteroids reduce tumour-related oedema and nerve compression pain. Anticonvulsants and antidepressants treat the neuropathic component of cancer pain. Bisphosphonates and newer bone-targeting agents reduce pain from bone metastases.
The limitation of the WHO ladder is that it relies entirely on systemic medication — drugs distributed throughout the entire body to reach the pain source. At higher doses, opioids produce side effects — sedation, constipation, nausea, and cognitive impairment — that significantly reduce quality of life. When systemic medication alone is inadequate or its side effects are unacceptable, interventional procedures offer a fundamentally superior approach for specific pain indications.
Coeliac Plexus Neurolysis — Transforming Pancreatic and Abdominal Cancer Pain
For patients with pancreatic cancer, advanced gastric cancer, or liver cancer producing severe upper abdominal and back pain, coeliac plexus neurolysis is one of the most dramatically effective pain procedures available. The coeliac plexus is a network of nerves at the back of the abdomen that transmits pain signals from the upper abdominal organs to the brain. When this network is chemically ablated — by injecting alcohol or phenol directly into it — pain transmission from the affected organs is interrupted, providing sustained relief that dramatically reduces opioid requirements.
The procedure is performed under CT guidance, which allows the interventional radiologist to position the needle with precision at the coeliac plexus while visualising the surrounding aorta, kidneys, and other critical structures in real time. The entire procedure takes under one hour under local anaesthesia with mild sedation. Clinical studies consistently report significant pain reduction in the majority of patients, with many experiencing relief lasting months — improving not just pain scores but overall quality of life, appetite, and functional capacity during a profoundly difficult period.
Image-Guided Nerve Blocks for Targeted Cancer Pain Relief
When cancer pain arises from specific identifiable nerve pathways — a tumour compressing a nerve root, cancer invading the pelvis and stimulating the hypogastric plexus, or localised nerve involvement — image-guided nerve blocks deliver local anaesthetic and neurolytic agents directly to the affected nerve under fluoroscopic or CT guidance.
Hypogastric plexus neurolysis addresses pelvic cancer pain from cervical, bladder, rectal, and ovarian cancers that has not responded adequately to systemic medication. Intercostal nerve blocks treat localised chest wall pain from rib metastases or post-thoracotomy pain syndrome. Lumbar sympathetic blocks address pain from lower limb vascular insufficiency caused by tumour compression. Each of these procedures delivers targeted treatment to the precise anatomical source of pain, achieving relief that systemic medication alone cannot produce without unacceptable side effects.
Vertebroplasty for Pathological Vertebral Fractures
Bone metastases frequently involve the vertebral bodies of the spine — weakening them progressively until they collapse under normal loading, producing pathological fractures that cause sudden, severe, and debilitating back pain. These fractures often prevent patients from sitting, standing, or walking comfortably during what may be the most important months of their lives.
Vertebroplasty — the image-guided injection of bone cement into a fractured vertebral body under fluoroscopic guidance — stabilises the fracture and provides rapid pain relief that oral medication cannot achieve for this specific pain mechanism. Many patients who were bedbound before vertebroplasty are significantly improved within 24 to 48 hours. For cancer patients whose treatment goals centre on quality of life, this rapid restoration of mobility and pain relief is genuinely transformative.
Palliative Intent Does Not Mean Inadequate Treatment
One of the most important principles in cancer pain management is that palliative care — care focused on comfort and quality of life rather than cure — demands the same standard of clinical rigour and the same access to advanced treatment options as curative care. A patient whose cancer cannot be cured is not a patient whose pain cannot be treated effectively. The most advanced pain management procedures are frequently most valuable precisely in the palliative setting, where they provide the comfort and functional capacity that makes meaningful time with family possible.
