Question 6
Question
Types of Lung Cancer
1. Non-Small Cell Lung Cancer
[blank_start]80-85[blank_end]% of lung cancers. Origin from [blank_start]epithelial[blank_end] cells. Includes adenocarcinomas, squamous cell carcinomas, large cell carcinomas. Staged using [blank_start]TNM[blank_end]. Better [blank_start]survival[blank_end] outcomes.
2. Small Cell Lung Cancer
[blank_start]5-20[blank_end]% of lung cancers . Origin from [blank_start]nerve producing[blank_end] cells in bronchi. Rarely occurs in [blank_start]non-smokers[blank_end]. Limited vs. Extensive staging. Rapidly [blank_start]spreading[blank_end] (metastases); poor [blank_start]prognosis[blank_end].

Question 7
Question
Which of these is NOT a feature of an adverse (poor) prognosis?
Question 8
Question
Staging NSCLC
Stage 0 – [blank_start]carcinoma in situ[blank_end]
Stage 1 – small tumor (<[blank_start]3[blank_end]cm), [blank_start]no[blank_end] lymph node involvement or mets
Stage 2 – small to medium tumor (<3cm or 3-[blank_start]5[blank_end]cm), [blank_start]regional lymph[blank_end] node involvement, no metastases
Stage 3 – medium to large tumor, more [blank_start]extensive[blank_end] lymph node involvement, no metastases
Stage 4 – any size / lymph node involvement, [blank_start]presence[blank_end] of metastases
Answer
-
carcinoma in situ
-
3
-
no
-
regional lymph
-
presence
-
5
-
extensive
Question 9
Question
Match the stage to the estimated 5 year survival rate. (Randomised order.)
53-60% - Stage [blank_start]2[blank_end]
77-92% - Stage [blank_start]1[blank_end]
13-36% - Stage [blank_start]3[blank_end]
0-10% - Stage [blank_start]4[blank_end]
Question 10
Question
Match the Tx to the staging.
Stage 0 - [blank_start]Surgery[blank_end]
Stage I - [blank_start]Surgery, Radiation[blank_end]
Stage II = [blank_start]Surgery, Radiation, Adjuvant CT,[blank_end] ?Neoadjuvant CT
Stage III - Surgery, Radiation[blank_start], Adjuvant CT, Neoadjuvant CT,[blank_end]
Stage IV - [blank_start]Combination[blank_end] CT, monoclonal [blank_start]antibodies[blank_end], maintenance therapy, EGFR tyrosine kinase inhibitor (EGFR mutations), ALK inhibitors (ALK translocations), ROS1 inhibitors (ROS1 rearrangements), BRAFV600E and MEK inhibitors (BRAFV600E mutations), immune checkpoint inhibitor, local therapies…

Question 11
Question
Treatment – Stage II
Adjuvant (post-primary tx):
- [blank_start]Cisplatin[blank_end] based therapy (5 year survival absolute benefit of 5.4%)
- Combination drugs include [blank_start]vinorelbine, etoposide, vinca alkaloid [blank_end]
Neoadjuvant (pre primary Tx)
Absolute benefit of 5 year survival of 6% across all stages. Largest study (most patient Stage I) showed [blank_start]no[blank_end] survival benefit. Controversial.
Question 12
Question
Treatment – Stage III
Adjuvant -

[blank_start]Cisplatin and vinorelbine[blank_end] typically regimen of choice .
[blank_start]Durvalumab[blank_end] immunotherapy for patients with no progression after 2 or more cycles of chemoradiation therapy) - interim analysis showed progression-free survival [blank_start]16.8[blank_end] months (durvalumab) vs. 5.6 months placebo (HR 0.52).

Question 14
Question
SCLC Tx
Limited disease standard Tx = [blank_start]Cisplatin / Etoposide[blank_end] (21 day cycle x 4 cycles)\
Extensive disease standard Tx = [blank_start]Doxorubicin / Vincristine[blank_end] / Cyclophosphamide (21 day cycle x [blank_start]4-6[blank_end] cycles). Can also use cisplatin / etoposide as above.
