Cloud-Based Lung Tumor Detection and Stage Classification Using Deep Learning Techniques

Table 5

Lung tumor stages classified based on its size.

Primary tumor (TU)
TU0	Tumor not occurs
TU1	Tumor size is less than or equal to 3 cm
TU1a	Tumor size is less than or equal to 1 cm
TU1b	Tumor size is more than 1 cm but less than or equal to 2 cm
TU1c	Tumor size is more than 2 cm but less than or equal to 3 cm
TU2	Tumor size is more than 3 cm but less than or equal to 5 cm
TU2a	Tumor size is more than 3 cm but less than or equal to 4 cm
TU2b	Tumor size is more than 4 cm but less than or equal to 5 cm
TU3	Tumor size is more than 5 cm but less than or equal to 7 cm
TU4	Tumor size is more than 7 cm
Region lymph nodes (LN)
LN0	Absence of regional node metastasis
LN1	Metastasis is in the ipsilateral peribronchial or perihilar lymph nodes and intrapulmonary nodes
LN2	Metastasis is in the ipsilateral mediastinal or subcarinal lymph nodes
LN3	Metastasis is in the contralateral mediastinal lymph nodes, perihilar lymph nodes, or supraclavicular nodes
Distant metastasis (DM)
DM0	Absence of distant metastasis
DM1	Malignant pleural/pericardial effusion or pleural/pericardial nodule or separate tumor nodule in a contralateral lobes
DM2	Distant metastasis was found
