To determine the role of noninvasive, minimally invasive diagnostic modalities and current management recommendations for cN0 PNC, a literature review using PubMed and Web of Science search engines were conducted. We found that for predicting ILN+: physical exam has limitations, nomograms are not validated, conventional computerized tomography/magnetic resonance imaging/positron imaging tomography scans have minimal role, and dynamic sentinel lymph node biopsy is the most reliable minimally invasive modality. Adverse pathological features: G3, stage ≥ T2, presence of LVI, and rare histopathological variants are important predictors of ILN+ and their presence warrants prophylactic ILND or dynamic sentinel lymph node biopsy. In the absence of these adverse pathological features conservative management is justified.
