Key practice points:
- Post-cancer treatment, primary care providers should receive a copy of the patient’s management summary from the treating
specialist, including treatments received, adverse effects, outcomes, any advance care plans, and frequency, duration
and scope of follow-up
- Patients should have their first follow-up appointment with the treating specialist within six weeks of completing treatment,
and if there are unresolved complications a second appointment at three months post-treatment. Longer-term follow-up
and supportive care of patients and their family/whānau can often be provided in the community, with a clear pathway back
to secondary care if required.
- Check that the patient has a chest X-ray scheduled for three months post-treatment, to be reviewed by the treating specialist.
Additional imaging should be requested as required to investigate new symptoms or signs; surveillance with chest
X-ray or laboratory investigations is not recommended routinely in primary care but may be part of ongoing specialist follow
up.
- Pain, fatigue, dyspnoea and cough may persist following lung cancer treatment; a variety of non-pharmacological and
pharmacological interventions are available to help patients manage these. If symptoms resolve post-treatment but then
recur, this would raise suspicion of lung cancer recurrence or delayed morbidity, e.g. pulmonary fibrosis post-radiation
therapy.
- Approximately half of people who undergo curative-intent lung cancer surgery will have recurrence; recurrence rates
are higher in those treated with radiation or chemotherapy. The majority of lung cancer recurrence happens within the first
two years post-treatment.
- Symptoms and signs associated with local recurrence are similar to primary lung cancer and include persistent cough,
breathlessness, haemoptysis, chest/shoulder pain, weight loss, abnormal chest signs, recurrent chest infections and hoarseness.
Recurrence at distant sites commonly occurs in the pleura, adrenal glands, bone, liver or brain.
- A chest X-ray is usually the first investigation if local recurrence is suspected. Consider CT and/or re-referral to
specialist or palliative care depending on local pathways and patient’s symptoms and signs and goals of care/advanced care
plan. A lung cancer nurse specialist, if available, may be a good initial point of contact.
- Consider the patient’s and family/whānau’s physical, psychological, social and spiritual needs; refer to the
Cancer
Society NZ or Lung Foundation NZ for support throughout the patient’s cancer journey
This article is based on expert guidance from the National Lung Cancer Working Group. A National guidance document for follow up and supportive
care for people with lung cancer is currently under development.
Transitioning from active treatment to post-treatment care is an important milestone in the long-term health of people
with lung cancer, and consistent follow-up and surveillance is necessary to ensure equitable outcomes for those who have
undergone curative-intent* treatment.1, 2 However, there is variability in the provision of this care
across the country, with many potential contributing factors, including:2
- Patient/whānau: co-morbidities, priorities and preferences, geographical and social isolation
- Clinical pathway: expected or unexpected health complications
- Cancer: histology, stage and prognosis, effectiveness of adjuvant and second-line interventions and
surveillance (see: “Lung cancer treatment and survival in New Zealand”)
- Access: availability of resources or services
- Co-ordination: strength of links between tertiary, secondary and primary health services and community
support services
*Curative-intent treatments in New Zealand include surgery, radical radiotherapy (including stereotactic
ablative radiotherapy) or chemo-radiotherapy (not always given with curative intent)2
The goals of post-treatment care
The main goals of post-treatment care are to:1–3
- Prevent and detect recurrent or new cancers to enable timely and appropriate management
- Prevent, identify and manage medical and psychosocial late or chronic effects of cancer and cancer treatment
- Co-ordinate care between all providers to ensure the patient’s needs are met
- Help the patient to gain greater independence and self-management of their ongoing health and wellbeing
Surveillance for lung cancer recurrence and new cancer development
Recurrence and second primary cancer rates following lung cancer are variable and influenced by many factors, including:4, 5
- Ongoing risk factors, e.g. smoking
- Characteristics of the original malignancy
- Increased contact with healthcare leading to detection and diagnosis of a second primary cancer
Approximately half of people with lung cancer who undergo curative-intent surgery will have a local or distant
recurrence,6 with higher rates in those with larger tumours or occult lymph node metastases. The risk
of lung cancer recurrence is greatest within the first two years post-treatment.6 Distant recurrence often occurs
earlier than local recurrence.7 Local recurrence following surgery is reported in approximately one-quarter
of cases.8 Approximately 40% of people with limited stage small cell lung cancer (SCLC) will have recurrence
within the first year following chemoradiation, increasing to 60% in the first three years following treatment.6 Treatment
options following recurrence of SCLC may be limited; treatment is often palliative and symptom-based, but oligometastases* can
be treated curatively and second-line palliative treatments can improve quality of life and survival. For people with non-small
cell lung cancer (NSCL), treatment options and outcomes are more variable, depending on the specific type of cancer and
access to treatments.
*Metastatic disease (i.e. distant spread of cancer) that is limited in the extent, number and
distribution of tumours, responsive to local treatment
People who have had lung cancer are at risk of any second primary cancer; common second cancers include
head and neck, thyroid, pancreatic and bladder cancers.4 The risk of developing a new primary lung cancer two
or more years following curative-intent treatment is 1.5 – 2% per year.6
Primary care is well placed to provide follow-up and surveillance care
While follow-up of people treated for lung cancer has traditionally taken place in secondary care, in many instances this
can be provided in the community, e.g. by a general practitioner or nurse practitioner, or via outpatient services with
a clinical nurse specialist.2 One of the benefits of primary care-led follow-up is the provision of “survivorship”
care that encompasses the patient’s cancer-related care, as well as management of co-morbidities and other health and wellbeing
needs, including lifestyle interventions (e.g. smoking cessation, reducing alcohol intake, improved diet) and psychological
support (see: “Psychological symptoms and cognitive changes following lung cancer treatment”).9 Potential
issues with primary care-led follow-up include the time constraints on general practice and additional cost to patients
of primary care appointments, which can be a significant factor. Telephone follow-up with a nurse, where appropriate, may
help to mitigate this cost for the patient.
A lung cancer toolkit for patients has been developed by the Lung Foundation NZ:

Lung cancer treatment and survival in New Zealand
Te Aho o Te Kahu, Cancer Control Agency, released a lung cancer quality improvement monitoring report early in 2021 that
included data on treatment and survival. Key findings of the report included:10
- The survival rate for people diagnosed with lung cancer between 2015 and 2017 was 42% at one year, 38% at two years
and 21% at three years post-diagnosis
- Survival rates were lower in Māori, males and people living in areas of high socio-economic deprivation
- Between 2015 and 2018:
- 17% of people with NSCLC underwent curative surgical resection; rates were lowest in Māori (13.4%) and Pacific peoples
(12.2%)
- 30% of people with NSCLC and 70% with SCLC received systemic anti-cancer treatment
- 6% of people with NSCLC and 11% with SCLC received concurrent chemotherapy and radiation treatment
The full report is available from:
https://teaho.govt.nz
The primary care provider and patient should have access to a treatment summary
On completion of cancer treatment, it is the treating specialist’s responsibility to share a copy of the patient’s treatment
summary with their primary care provider (this should be able to be accessed electronically via a shared record storage
system); a plain language summary should also be provided to the patient and their family/whānau.2
The treatment summary should contain information on the:2
- Diagnosis
- Treatments
received and when completed
- Long-term
adverse effects that may occur and any laboratory monitoring or other investigations required
- Documentation
that the patient and their family/whānau understand the diagnosis and treatment, that prognosis has been discussed
and any advance care planning
- Symptoms
and signs that may indicate recurrence and need for further investigation
- Contact
information for key care providers
- Follow-up
plan that includes the providers involved, the frequency/ duration of follow-up (typically five years) and clear
lines of responsibility
The frequency and type of follow-up care is individualised
The frequency and type of follow-up care will be specified in the treatment plan. All patients should have a follow-up
appointment with the treating specialist within six weeks of completing treatment to assess for complications and to discuss
ongoing care. If there are unresolved complications of treatment, a second review with the treating specialist should take
place at three months post-treatment.2 Many patients can have their longer-term follow-up and supportive care
provided in the community, in accordance with their treatment plan. Other healthcare providers who may be involved, depending
on the needs of the patient, include physiotherapy, occupational therapy, social work, dietetics, counselling and palliative
care.
Routine chest X-ray is not recommended for surveillance
There is limited evidence to guide the use of routine surveillance imaging following curative-intent lung cancer treatment.2 The
National Lung Cancer Working Group recommends all patients undergo a chest X-ray at three months post-treatment, reviewed
by the treating specialist.2 Additional imaging (repeat chest X-ray or referral* for chest CT)
should be requested based on symptoms and signs, but in some instances may be requested by the specialist as part of routine
surveillance (see: “Recognising lung cancer recurrence: key symptoms and signs”).2
A small number of patients may benefit from more intensive follow-up with chest CT, e.g. those with indeterminate pulmonary
nodules, where the risk of recurrence is high and active or curative treatment would be considered, or if the risk of new
cancers is high, such as patients with a known mutation who may be suitable for targeted therapy.2 These patients
are usually followed up by secondary care.
*In some DHBs, general practitioners may be able to refer directly for chest CT, with or without advice from a respiratory
physician or radiologist
Surveillance for recurrence can cause anxiety and distress
Ensure that the patient and their family/whānau understand the purpose of the appointments, the recommended schedule and
what to do if they have symptoms or concerns that arise before a routine follow-up appointment.2 Some patients
may request additional imaging for reassurance; discuss the risks associated with imaging, e.g. radiation exposure, and
that the risk of false positives increases when imaging is undertaken in the absence of clinical suspicion.2
Recommend Advance Care Planning if not already in place
Ideally, Advance Care Planning (ACP) will have been discussed and put in place by the treating team after the patient’s
cancer diagnosis. The transition to post-treatment care is an opportunity for the patient and their family/whānau to review
the care plan or establish one if they have not already done so.
For further information on Advance Care Planning, see:
https://www.hqsc.govt.nz/our-programmes/advance-care-planning/information-for-clinicians/
Achieving equity in cancer care for Māori by 2030
In 2019, at the Cancer Care at a Crossroads conference convened by the University of Otago and Cancer Society of New Zealand,
the goal to achieve equity in cancer survival between Māori and non-Māori by the year 2030 was agreed.11 This
requires a systems-level approach that addresses inequities at each stage of the cancer journey, including prevention, early
diagnosis, availability, affordability and acceptability of treatments, follow-up and survival care.11
The key areas of contribution for primary care are in the prevention, early detection (see link below) and follow-up and
surveillance of cancer. Lung cancer incidence and mortality rates are over three times higher in Māori than non-Māori.12,
13 High tobacco smoking rates among Māori is an important contributing factor to the high incidence of lung cancer
in this group, therefore encouraging and supporting smoking cessation is a key priority (see: “Encourage and support smoking cessation”).
Equitable and accessible follow-up and supportive care should be consistent throughout the country.
This should include patient education about the importance of follow-up care, key symptoms and signs that could indicate
recurrence and the support services available. If transport or cost is a barrier to attending follow-up appointments, consider
whether some consultations could be by phone or with a nurse. Ensuring that co-morbidities are well managed is also essential
to improving survival rates among Māori.14 Māori have higher rates of co-morbidities, which increases the complexity
of care if lung cancer is diagnosed, and reduces treatment options, e.g. eligibility for curative surgical resection.14
For further information on early detection of lung cancer, see:
https://bpac.org.nz/2021/lung-cancer.aspx
The nature, severity and duration of symptoms following lung cancer treatment is influenced by various factors, including
the type, extent or intensity of treatment, the patient’s general health status, co-morbidities, psychosocial and lifestyle
factors, e.g. smoking, diet and exercise.15 There may be symptoms or signs caused by complications from the cancer
itself, e.g. hypercalcaemia, which can affect up to 30% of people with cancer.16
Patients with late/long-term physical or psychological effects (see below) can typically be managed in primary care; patients
with post-treatment complications should be discussed with or referred to the relevant specialist, e.g. a patient with dyspnoea
post-radiation therapy may be referred to a respiratory physician, a patient with cardiac failure referred to a cardiologist
or a patient with oesophageal stricture referred to a gastroenterologist (see: “Post-treatment
complications vary by treatment type”).
Physical symptoms following lung cancer treatment
A systematic review including 19 studies of people with NSCLC who were treated with surgery found:17
- Pain, fatigue, dyspnoea and cough were the most commonly reported symptoms; dyspnoea
and fatigue persisted for at least two years post-surgery
- The majority had decreased physical functioning after surgery; this persisted for up to two years in
some people
- Continued smoking, the presence of co-morbidities, more extensive surgical resection and adjuvant chemotherapy whilst
receiving it were associated with poorer post-operative quality of life
- Other common physical symptoms following lung cancer treatment include reduced appetite, malnutrition and insomnia
Non-pharmacological approaches to managing physical symptoms:18, 19
Encourage and support smoking cessation
The key opportunity to encourage and support smoking cessation is at the time of lung cancer diagnosis, and many people
will stop at this point. Smoking cessation rates among people who have undergone cancer treatment gradually decrease over
time.20 However, restart rates are reported to range from 13 – 60%.20 Factors contributing to this
may include nicotine withdrawal, pain, fatigue, nausea, depression and anxiety.20
The ABC model can be used as a guide to offer support and encouragement to stop smoking:
- Ask about and document smoking status, including use of e-cigarettes and exposure to passive smoking
- Give Brief advice to stop
- Strongly encourage the use of Cessation support and offer help in accessing this, and refer to services
if this offer is accepted. A combination of behavioural support and pharmacological treatment is ideal.
Pharmacological treatments approved for smoking cessation include nicotine replacement therapy, bupropion, nortriptyline
and varenicline (with Special Authority approval – currently out of stock as at October, 2021).21
For further information on smoking cessation, see:
https://bpac.org.nz/BPJ/2015/October/smoking.aspx
For further information on smoking cessation medicines, including dosing and regimen, contraindications and
cautions, see: https://www.nzf.org.nz/nzf_2838
Physical activity recommendations for people treated for lung cancer
General practice is well placed to co-ordinate and recommend exercise interventions for people who have undergone lung
cancer treatment. There is a range of benefits of exercise in cancer survivors, including improved physical and mental health,
symptom reduction and improved quality of life.19 Tolerance to exercise will vary depending on where the patient
is in their cancer journey; encourage patients to engage in as much physical activity as possible and to reduce sedentary
periods.19 Recommendations should be individualised, taking into account patient preferences, abilities, symptoms,
co-morbidities and safety.19 Refer patients who are unable to exercise safely without supervision or those requiring
additional support to an exercise professional, e.g. pulmonary rehabilitation programme, cancer rehabilitation programme
(e.g. Pinc and Steel NZ – see link below), Green Prescription.
A downloadable exercise template for people with cancer is available from:

Pharmacological interventions to manage physical symptoms after lung cancer
Pain – follow the World Health Organization’s analgesic ladder for pain:22
- Oral morphine is recommended first-line for patients with severe chronic pain; transdermal fentanyl is an alternative
if there are issues with swallowing, nausea or vomiting
- A gabapentinoid or tricyclic antidepressant are recommended for patients with chronic neuropathic pain23
- If a NSAID is prescribed and the patient is at high risk of gastrointestinal bleeding, prescribe a proton pump inhibitor
(PPI) concurrently
Dyspnoea – treat any underlying causes or contributing factors, e.g. COPD, anaemia, lung
infection; symptomatic treatments include:22
- Behavioural interventions such as a hand-held fan
- Low dose oral morphine
- A benzodiazepine may be prescribed short-term for acute management of panic attacks associated with dyspnoea (anxiety-dyspnoea-anxiety
cycle)24
- Oxygen if hypoxic
Cough – treatment depends on the cause of cough, e.g. infection secondary to treatment,
co-morbidities such as COPD or asthma:22
- Opioid, e.g. codeine or oral morphine, to suppress cough (unapproved indication)
- Bronchodilator – if bronchospasm is causing or contributing to cough
- Inhaled corticosteroid (ICS) – for cough attributed to chemotherapy or radiation treatment; first discuss with an oncologist
or other treating specialist and consider the increased risk of lower respiratory tract infection with high doses of ICS 25
- Antibiotics – if concurrent respiratory infection
Insomnia – use short-term in conjunction with non-pharmacological approaches:22
For information on contraindications and cautions, dosing and treatment regimens for the listed medicines,
see the New Zealand Formulary: https://www.nzf.org.nz/
Psychological symptoms and cognitive changes following lung cancer treatment
People who have undergone treatment for cancer may experience psychological symptoms such as fear of recurrence, insecurity
about their future, guilt or shame, distress, depression and anxiety.17, 26 Studies measuring mental health-related
quality of life (HRQoL) among people with NSCLC treated with surgery found that the majority of patients had improved mental
HRQoL after surgery compared to prior to surgery, but lower mental HRQoL compared to the general population.17 Approximately
one-quarter to one-third of patients continued to have worse mental HRQoL after surgery and distress persisted over time.17 Health
practitioners should be vigilant for new onset or worsening psychological symptoms in people who have undergone lung cancer
treatment; a screening tool for depression or anxiety can be used, e.g. the PHQ-9 or GAD-7.
For further information on screening tools for distress and depression, behavioural and pharmacological interventions,
see: https://bpac.org.nz/2019/ssri.aspx
For further information on SSRIs and other pharmacological treatments, see:
https://bpac.org.nz/2021/depression.aspx
Cognitive changes following lung cancer treatment
Many people who have undergone cancer treatment, particularly chemotherapy, report cognitive changes, including difficulty
concentrating and short-term memory loss. Cognitive impairments associated with chemotherapy are typically transient, resolving
in the months following the completion of treatment.27, 28
The Cancer Society provides support to people with cancer and their family/whānau:
https://www.cancer.org.nz/supporting-you/how-we-can-help/
Post-treatment complications vary by treatment type
A number of complications may develop after completing lung cancer treatment, including:
- Infection – at the wound site, pneumonia, increased infection risk with radiation/chemotherapy immunosuppression30
- Radiation or chemotherapy-induced pneumonitis – typically develops one to three months post-treatment,
but can occur up to six to 12 months post-treatment.23 Presentation includes cough, dyspnoea, chest pain, rales
and hypoxaemia; radiographic changes may include volume loss and patchy infiltrates.23
- Peripheral neuropathy due to chemotherapy – can involve sensory, motor or autonomic systems; typically
reversible, with the median time to recovery of 13 weeks23
- Cardiovascular complications – damage can occasionally occur to cardiac muscle with radiation treatment
if cardiac structures are encompassed in the radiation field, causing complications such as coronary artery disease, valvular
changes, myocardial fibrosis, pericarditis, dysrhythmias23
Co-morbidities are common in people with lung cancer. A cross-sectional study of 565 people with lung cancer in New Zealand
found that 81% of people had at least one co-morbidity that could potentially influence management.31 Nearly
50% of people with lung cancer had COPD, 38% had a cardiovascular co-morbidity, 16% had a cerebrovascular co-morbidity and
13% had diabetes.31 The presence of co-morbidities can limit treatment options and is associated with an increased
risk of post-treatment complications and worse survival outcomes.32, 33
Management of long-term conditions may have taken lower priority during active cancer treatment;14 post-treatment
there is an opportunity to assess long-term condition management, review treatments and management goals.14
Regularly review medicines
Regularly review medicines to ensure that appropriate medicines are continued, and doses are adjusted as required, e.g.
if the patient loses weight during cancer treatment. Depending on prognosis, consider discontinuing preventative medicines
that may no longer be required, e.g. statins for hyperlipidaemia, intensive use of blood glucose-lowering medicines. Emphasise
that this does not signify that you are giving up on them and frame the conversation around providing the best balance of
benefits and risks.
For further information on stopping medicines, see: https://bpac.org.nz/2018/stopping.aspx
Recommend vaccinations
Annual influenza vaccination is recommended for all people who have undergone lung cancer treatment.2 Immunisation
should be delayed until three months post-chemotherapy, unless the patient is at high risk, in which case it may be given
earlier, e.g. high rates of circulating influenza in the community. Two doses, administered four weeks apart, are recommended
in the first year following chemotherapy, however, only the first dose is funded.34
COVID-19 vaccination is strongly encouraged for all people aged over 12 years, including those with cancer;
follow national protocols for dosing advice.
Further information on COVID-19 for people with cancer is available from Te Aho o Te Kahu, Cancer Control
Agency: https://teaho.govt.nz/cancer/covid19
Ensure other immunisations are up-to-date
Booster dose(s) of the following vaccines are recommended and funded for people who have undergone cancer chemotherapy:35
- A diphtheria/tetanus/pertussis-containing vaccine
- Hepatitis B
- Polio (IPV)
- Pneumococcal vaccines (PCV13 followed by 23PPV)
- MMR – if born in 1969 or later and no documented evidence of two doses of MMR
N.B. Live vaccines should be administered no earlier than six months post-treatment and when the lymphocyte count is > 1.0
× 109/L; inactive vaccines can be administered from three months post-treatment once the patient’s lymphocyte
count is > 1.0 × 109/L.35
Table 1 lists the key symptoms and signs of local or distant lung cancer recurrence. The site and
extent of recurrence determines the pattern of symptoms.36 Systemic symptoms or signs such as anorexia, fatigue,
weakness and unexplained weight loss may also indicate cancer recurrence.36 The treatment summary will provide
advice on the key symptoms and signs that require referral back to the treating specialist and the relevant contact information.2
N.B. The majority of patients will have cough and dyspnoea post-treatment, but a change in symptoms, a worsening cough
or a sudden increase in dyspnoea or a return of symptoms after resolution may indicate cancer recurrence.
Urgent medical attention is indicated for people with:37, 38
- Massive haemoptysis
- Signs of airway obstruction, e.g. stridor (as distinct from wheeze) or respiratory distress
- Signs of superior vena cava obstruction, e.g. dilated veins in neck or over chest, swollen face or head, redness of
face, visual symptoms, dizziness, headache
- Symptoms or signs of spinal cord compression
