Primary Salivary Gland Malignancy: A Review on Post-Operative Follow-Up Duration and Radiological Modalities

Salivary gland cancers (SGC) are rare neoplasms that exhibit a wide array of histological heterogeneities. Most patients presenting with SGCs are asymptomatic, as they are typically slow-growing and localized. Primary surgical resection is the cornerstone treatment for SGCs and radiotherapy is performed in selected cases. There is no consensus on concrete standard post-operative guidelines. Patients are followed-up for years, however an agreed duration of follow-up is less elucidated in the literature present on the subject. Distant metastases are the primary cause of treatment failure. Post-operative diagnostic evidence of disease recurrence or distant metastases is heavily guided by radiological examinations. Patients with SGCs have better outcomes with a well-structured and lengthy follow-up plan. This review aims to suggest an appropriate follow-up duration and radiological modalities used post-operatively for SGC patients.
