Local Treatment Recommendations for Cancer on the Toe

Primary Treatment Approach

The National Comprehensive Cancer Network recommends surgical excision with adequate margins as the standard treatment for malignant tumors on the toe, with the specific approach depending on tumor type, thickness, and invasiveness 1, 2

The National Comprehensive Cancer Network recommends amputation at the distal phalanx with a margin of normal-appearing skin for subungual melanoma 2
The British Journal of Cancer suggests that surgical margins should be based on Breslow thickness:
The National Comprehensive Cancer Network recommends considering the level of amputation, with traditional recommendations including distal interphalangeal joint for fingers and metatarsophalangeal joint for toes, while a more conservative approach involves amputation of distal phalanx with margin of normal skin 2

The National Comprehensive Cancer Network recommends limb-sparing surgery with wide local excision as the preferred approach over radical amputation for soft tissue sarcomas of the hand and foot 4, 5, 6, 7
The National Comprehensive Cancer Network suggests that surgical margin requirements include a resection margin of ≥1 cm, which is associated with 0% local recurrence 4, 5, 6
The British Journal of Cancer recommends postoperative radiation: 60-66 Gy in 1.8-2 Gy fractions, and preoperative radiation: 50-50.4 Gy in 1.8-2 Gy fractions 8

The British Journal of Cancer recommends considering ILP for locally advanced sarcomas where limb preservation may not otherwise be possible, but only at specialized centers 8, 9
The British Journal of Cancer suggests that ILP achieves tumor shrinkage, rendering tumors operable by marginal resection with excellent local control, and complete response rates of 58% with low toxicity when leakage is controlled (<1%) 8, 9

The National Comprehensive Cancer Network recommends reserving amputation for cases where surgical excision or re-excision with adequate margins cannot be performed without sacrificing functionally significant neurovascular or osseous structures 4, 5, 6, 7

The National Comprehensive Cancer Network recommends regular clinical examination as the primary surveillance strategy, and baseline radiologic imaging is not recommended for asymptomatic patients with clinically node-negative disease 3
The Praxis Medical Insights suggests that imaging should only be performed to evaluate specific signs or symptoms of potential metastasis, and for melanoma, ultrasound of regional lymph node basin should be considered if sentinel lymph node biopsy criteria are met but procedure not performed 3

The National Comprehensive Cancer Network recommends avoiding immediate radical amputation without attempting limb-sparing surgery first, as it does not improve survival 4, 5, 6, 7
The British Journal of Cancer suggests avoiding the use of radiation as a substitute for suboptimal surgical resection, and avoiding nail bed excision with skin grafting for subungual melanoma due to poor functional outcomes 2, 6, 8
