High lights Epidemiology of Lung cancer Presentation and diagnosis Staging Treatment in general Surgical treatment Questions?

Epidemiology of Lung cancer Most frequently diagnosed cancer worldwide – About 1.35 million new cases diagnosed worldwide each year Leading cause of cancer deaths in the United States

Canadian Cancer Statistics 2015

Epidemiology of Lung cancer For men in Ontario, prostate cancer is the most frequently diagnosed type of cancer. In 2015: An estimated 9,700 men will be diagnosed with prostate cancer. An estimated 5,100 men will be diagnosed with colorectal cancer. An estimated 4,600 men will be diagnosed with lung cancer

Risk factors Cigarette smoking Second-hand smoke Occupational exposure (asbestos, motor vehicle emissions, pollutants, radon) Genetics Low level radiation Smoking and low intake of beta carotene.

Cell types

Presentation Symptoms: Some of the early warning signs of lung cancer are: A cough that doesn’t go away Chest pain Hoarseness Weight loss and loss of appetite Bloody or rust-colored sputum Shortness of breath Fever without a known reason Recurring infections such as bronchitis or pneumonia

Presentation

Investigation Chest X-Ray CT scan +/- Biopsy MRI PET scan Bone scan Bronchoscopy EBUS-TBA

Clinical Staging Imaging CT{ chest and upper abdomen } MRI Superior sulcus tumor, Pancoast – MRI Head if symptoms, Adenoca – for Small cell Lung cancer – May be in stage III disease NSCLC – All patient in academic centers !! PET- if a radical treatment is considered Bone scan, Complementary to PET ??

Clinical Staging – CT/US guided needle aspiration: thoracentesis, cervical lymph node, liver – EUS: left adrenal metastasis – In metastastatic disease, biopsy the easiest site

Clinical Staging CT scan Alone Was not very good Why? 40% of suspicious LN are benign by size criteria. 20% of non-suspicious LN are malignant. Meta-analysis: Sensitivity: 51-64%* Specificity: 77-82%** Clinical T1N0 ( 5-15% has positive LN on surgical staging)

Clinical Staging PET scan: Was not great too why? Systematic review of 44 studies; Sensitivity:74% Specificity:84% Meta-analysis: Enlarged LN Sensitivity:100% Specificity:78% False positive:25% Gold Ann Int med 2003;

Clinical Staging PET scan(continue): Meta-analysis: Non-enlarged LN Sensitivity:82% Specificity:93% False Negatice:20% Gold Ann Int med 2003;

Surgical treatment by stage Lobectomy Bilobectomy ( only Right side) Sleeve resection Pneumonectomy Segmentectomy Wedge resection Chest wall with Lung resections

Surgical treatment by stage Stage I &II Surgery is the main stay in treatment. There is a good body of evidence to support that.

Surgery for stage III-A Heterogeneous stage !! T1 to T3, N2, M0 T3, N1, M0 T4, N0 or N1, M0

Stage IIIa – “Bulky

Stage IIIa – “Minimal Involvement

Surgery for stage III-A Induction (pre-operative ) Chemo-radiotherapy for Stage III-a non- small cell lung cancer Standard of Care ???

Surgery for stage III-A Intergroup trial 0139 Chemo-radiation vs Chemo-radiation followed by surgical resection of Stage IIIa NSCLC Kathy Albain et al. ASCO 2005 Lancet 2009;374:379-86

Conclusion N0 at surgery greatly influence 5 years survival Trimodality therapy is not recommended if pneumonectomy is required due to high mortality Surgical resection can be considered in fit patient after induction chemo-rads if lobectomy is feasible.

Surgery for stage III-B No role for surgery Very bulky disease Any T, N3, M0 T4, N2, M0

Any T, any N, M1a Any T, any N, M1b The overall consensus: no role for surgery BUT ??!! Surgery for stage IV

Exception to this role: Solitary brain, pulmonary or adrenal mets Provided: 1.Thoracic disease is resectable(Ro resection) 2.Good performance status, younger patients 3.Mets are resectable with acceptable morbidity 4.Mediastinum is cleared.

Surgery for stage IV Any evidence Supported by several retrospective reviews.

Surgery for stage IV Metastasectomy for Synchronous Solitary Non-Small Cell Lung Cancer Metastases Mario Tönnies, MD, Joachim Pfannschmidt, MDcorrespondence , Torsten T. Bauer, MD, Jens Kollmeier, MD, Simone Tönnies, Dirk Kaiser, MD Between 1997 and 2009, 99 patients underwent complete solitary synchronous NSCLC metastasis resection in a single center. Conclusions They conclude that metastasectomy for synchronous oligometastatic disease in NSCLC can be performed in selected patients. It appears reasonable that such patients should be considered as surgical candidates if mediastinal lymph node involvement is excluded. Annals of Thoracic surgery.
