Q

Risk factors for lung cancer

A

• Smoking
○ Increases risk of lung ca by a factor of 10
○ Weaker association with lung adenocarcinoma
• Other factors
○ asbestos - increases risk of lung ca by a factor of 5
§ Smoking and asbestos are synergistic, i.e. a smoker with asbestos exposure has a 10 * 5 = 50 times increased risk
○ arsenic
○ Radon - 2nd leading cause of lung cancer
○ nickel
○ chromate
○ aromatic hydrocarbon
○ cryptogenic fibrosing alveolitis
• Factors that are NOT related
○ coal dust
• Family history (genetic predisposition)
• Other RF: pulmonary scarring, previous radiation, pulmonary fibrosis, chronic infections (eg: TB, HIV)

Q

Types of lung cancers

A

Lung cancer is divided into 2 types:
(1) Small Cell Lung Cancer 13%: central location, rapid tumour growth, early metastases and associated with numerous paraneoplastic syndromes

(2) Non-Small Cell Lung Cancer
- Adenocarcinoma (peripheral) - most common 40% and more common in women + non smokers
- Squamous cell carcinoma (central) 20%
- Large cell carcinoma 7%

Q

Treatment for SCLC

A

LIMITED
- Curable (20-30%) with concurrent chemoradiation (CISPLATIN + ETOPOSIDE) and PCI (prophylactic cranial irradiation) in responders as brain is a brain sanctuary site for micromets

EXTENSIVE

  • Generally incurable
  • BUT expect excellent response with chemo/RT even in very unwell patients
  • Median survival 12 months with chemoimmunotherapy

Chemotherapy (CARBOPLATIN + ETOPOSIDE) + ATEZOLIZUMAB (PDL1 inhibitor) improved PFS + OS

Q

Pancoast tumour

A

• Apical lung carcinoma
• Superior sulcus tumour
• Predominantly NSCLC
• May lead to the development of Pancoast Syndrome: constellation of symptoms secondary to the mass effect of the tumour on surrounding structures
○ Cervical sympathetic ganglion (stellate ganglion): Horner syndrome (ipsilateral miosis - small pupil), ptosis, anhidrosis)
○ Brachial Plexus: localised pain in the axilla and shoulder (plexus neuralgia)
- Upper limb motor and sensory deficits (eg: hand muscle weakness and atrophy) - wasting hand muscles (T1)
○ Recurrent laryngeal nerve: hoarseness
○ Brachiocephalic vein
- Unilateral oedema of the arm
- Facial swelling
○ Phrenic Nerve: paralysis of the hemidiaphragm (visible as elevated hemidiaphragm on CX

NOTE:
The right and left recurrent laryngeal nerves are not symmetrical, with the left nerve looping under the aortic arch, and the right nerve looping under the right subclavian artery then traveling upwards.

Q

Staging for NSCLC and basic treatment

A

Stage 1: No nodal involvement
- Surgical resection if medically fit - lobectomy vs pneumonectomy
Lobectomy with mediastinal LN dissection is recommended for tumours >2cm
- Stereotactic radiation if non surgical candidate

Stage 2 A+B: Ipsilateral peribronchial and/or hilar LN and intrapulmonary nodes
- Surgical resection + adjuvant chemo

Stage 3A: ipsilateral mediastinal and/or subcarinal LN
Stage 3B: contralateral mediastinal, hilar, supraclavicular LN
- Resectable: neoadjuvant chemo + surgical resection
- Unresectable: concurrent chemoradiation and DURVALUMAB (PDL1) for 12 months

Stage 4: metastatic disease including malignant pleural effusion + contralateral lung nodules
- Palliative systemic therapy - chemotherapy, targeted therapy and immunotherapy
+ palliative RT

Adjuvant Chemo

  • Consider for all fit stage II-III patients post resection
  • No conclusive benefit for stage IV
  • Generally 4 months of cisplastin + venorelbine

31
Mechanism of action of EGFR inhibitors with respect to cell cycle
Epidermal growth factor inhibitors (EGFRi) such as erlotinib (used in nonsmall cell lung cancer) and cetuximab (used in colorectal cancer and head/neck cancer) block the progression of a cell from the G1 phase to the S phase.
32
Features of the cell cycle
The cell cycle can be divided into two phases: interphase and mitosis. Interphase is further divided into the G1 (gap 1), S (synthesis), and G2 (gap 2) phases, which prepare the cell for division. - G1 Phase: proteins and cell organelles are synthesized. - S Phase: DNA is replicated in the S phase. - G2 Phase: DNA replication errors are repaired. - Mitosis (M) or cell division. - There are various checkpoints within the cell cycle that ensure the cell is ready to enter the next phase (G1, G2, and M checkpoints). - Only proliferating cells pass through the cell cycle. - Most mature tissue cells are in a resting phase, the G0 phase. - These cells are differentiated, with each performing a specific function. - Mature differentiated cells do not divide
33
Predictive vs prognostic biomarker
PREDICTIVE: provides information on OUTCOME with regards to SPECIFIC THERAPY PROGNOSTIC: provides information on OUTCOME, INDEPENDENT OF THE THERAPY that is used PREDICTIVE BIOMARKER: identify subgroups most likely to respond - provides information on the probability of obtaining a response to treatment - Allows for therapeutic decisions - EG: HER2/EGFR --> predicts will respond to treatment KRAS mutated --> predicts resistance to treatment PDL1 >50% --> predicts better response to immunotherapy BRAF in melanoma is PREDICTIVE not prognostic of response to BRAF inhibitors PROGNOSTIC BIOMARKER: provides information on course of disease - informs about a likely cancer outcome (eg, disease recurrence, disease progression, death) independent of treatment received. - reflects the underlying biology and natural history - treatment benefit similar for biomarker-positive and biomarker negative patient, but the biomarker will still be associated with a differential outcome depending on whether it is present or absent - the biomarker positive patients have a better survival than biomarker negative patients, independent of treatment group EG: EGFR IN LUNG CANCER
34
