Follow-up of melanoma: A survey of Italian hospitals

Follow-up is managed internally in 94% of centers and is programmed according to international guidelines in 52% of high-volume hospitals (>25 melanoma diagnoses per year); the remainder use internal guidelines; fewer low-volume centers (≤25 diagnoses per year) have internal guidelines (25%, p = 0.001). Instrumental examinations for stage III and IV disease are similar, while the examination interval changes from 3/4 months for stage III to 2/3 months for stage IV, and use of PET/CT increases from 44 to 54%. Overall, thoracic and abdominal CT is used most for follow-up in stage III (83%), while bone scintigraphy is used more commonly in low-volume centers (41 vs. 19%, p = 0.003), despite similar use of PET/CT (48 vs. 41%). Brain CT or MRI is more common in high-volume centers (63 vs. 39%, p > 0.0001), as is echography of draining lymph nodes (71 vs. 52%, p = 0.01). Hepatic/abdominal echography and thoracic radiography are used in about 50% of centers, regardless of type. In stage IV, use of bone scintigraphy is similar among groups (ca. 40%); brain CT/NMR use increases from 51 to 64% and is more common in high-volume centers (p = 0.03). Lymph node echography is more common in high-volume centers (56 vs. 39%, p = 0.03). Copyright © 2013 S. Karger AG, Basel.
