Palliative treatments for lung cancer:

What can the oncologist do?

Palliative Radiotherapy

Case Study

• 63 yr old man

• Stage 4 NSCLC

• WHO PS 1

• Pain in right hip

• Mobile

• No neurological signs

What next?

Radiotherapy for bone pain

• Systematic review 25 randomised trials, > 5500

patients

• Response rate

Any reduction in pain = 60%

Complete response = 23%

Overall and complete response rates 73% and 29% respectively

when excluding patients not assessed at follow-up

Response rate assessments ranged from 3 weeks to 3 months

Pain flare occurs in up to 40% patient following radiotherapy for

bone pain Hird IJROP 2009

Dexamethasone (8mg d1-5) reduces risk of pain flare

Chow, Lancet Oncol 2015

Guidelines

Royal College of Radiologists

For the initial therapy of pain from bone

metastases, a single fraction of 8 Gy is

recommended (Grade A)

months of life: Worthwhile or Futile?

Prospective, population-based Canadian study

• Response rates

• 70% at 1 month

• 63% at 2 months Dennis, Clin Oncol (R Coll Radiol) 2011

• 76% response rate overall

• 54-65% response rate in those dying < 3 months

Metastatic Spinal Cord Compression

(MSCC)

• > 4000 cases per year in UK

• Extradural compression or invasion from adjacent

metastatic vertebra

• Oncological emergency treated with surgery or

radiotherapy

Reversible

Venous obstruction

and oedema

Irreversible

Direct compression

• arterial compression

• axonal fracture

• neuropraxia

Immobility

Loss of sphincter control

• Validated score to

• Surgical selection

• Lung cancer poor

prognostic factor

Metastatic Spinal Cord Compression:

NICE guidance

1.5.1. Radiotherapy for painful spinal metastases

• Offer patients with spinal metastases causing non-mechanical spinal pain 8 Gy single fraction palliative radiotherapy even if they are completely paralysed.

• Patients with asymptomatic spinal metastases should not be offered radiotherapy with the intention of preventing MSCC except as part of a randomised controlled trial.

Metastatic Spinal Cord Compression:

NICE guidance

1.5.5 Radiotherapy for the definitive treatment of MSCC

• Urgent access (within 24 hours) to radiotherapy 7 days a week

• Offer a fractionated rather than a single fraction regimen to patients with a good prognosis.

• Routine fractionated radiotherapy to all patients after surgery

• Offer urgent radiotherapy (within 24 hours) to all patients with MSCC who are not suitable for spinal surgery unless:

• they have had complete tetraplegia or paraplegia for more than 24 hours and their pain is well controlled; or

• their overall prognosis is judged to be too poor.

SCORAD III

• Phase III RCT

• Eligibility

• MSCC

• Prognosis > 8 weeks

• Histological diagnosis

of malignancy

• Primary outcome

• Ambulation at 8 weeks

• Never smoked

• No co-morbidities

• Keen ballroom dancer

Case 2

What is it?

• Adenocarcinoma

• EGFR mutation

• Started 1st line Gefitinib (tyrosine kinase inhibitor)

1st line Iressa vs chemotherapy in NSCLC

with EGFR mutation N Engl J Med 2010;362:2380-8

October November

December January

• Symptoms resolved after 1st cycle

• Toxicity - Mild skin reaction (acneform rash over face

and dry skin)

• Restarted ballroom dancing

• Spent time visiting relatives and travelling with her

husband in SE Asia.

……with several boxes of gefitinib.

Prevention of Skeletal Related

Events (SRE)

• Bisphosphonates • Zolendronic acid (4mg every 3w for 9 months) reduced risk of

skeletal related events compared to placebo

• Increased time to first SRE

• NNT to prevent SRE at 9 months = 14 Rosen JCO 2003

• Denosumab • Non-inferior to ZA in delaying time to first SLE

Henry JCO 2011

• Improved OS compared to ZA on exploratory analysis (8.9 vs 7.7

months; hazard ratio [HR] 0.80, p=0.01) Scagliotti JTO 2012

Palliation of bone pain???

Take home messages

• Radiotherapy

• Very effective treatment for cancer induced bone pain and

heamoptysis

• Metastatic spinal cord compression is an oncological emergency

• Does not improve QALY for patients with brain metastases

(?young/good PS/controlled extracranial disease)

• Systemic therapy

• Can improve survival and offer holistic symptom relief

• Tissue for histological and molecular analysis is essential
