Summary

This study on malignant melanoma patients undergoing groin dissection found significant wound complications and lymphoedema. Thorough deep node dissection improved survival rates, especially when inguinal nodes were palpably positive.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Dermatology

Background:

  • Malignant melanoma is a significant health concern.
  • Groin dissection is a critical surgical procedure for melanoma staging and treatment.
  • Understanding complications and survival rates is essential for patient management.

Purpose of the Study:

  • To review complications and survival rates following groin dissection for malignant melanoma.
  • To assess the impact of lymph node involvement on patient outcomes.
  • To evaluate the effectiveness of deep node dissection in improving survival.

Main Methods:

  • Retrospective review of 205 patients who underwent groin dissection for malignant melanoma.
  • Documentation of wound complications, including necrosis, infection, lymphocele, and lymphorrhoea.
  • Analysis of 5-year and 10-year overall and disease-free survival rates based on lymph node involvement.

Main Results:

  • Wound complications observed: skin-edge necrosis (8%), wound infection (16%), lymphocele (5%), lymphorrhoea (11%).
  • Lymphoedema affected 40% of patients below the knee, with localized thigh oedema in all.
  • 5-year survival rates: 43% overall and 35% disease-free with inguinal node involvement; 34% overall and 21% disease-free with inguinal and deep node involvement.

Conclusions:

  • Groin dissection for malignant melanoma is associated with notable wound complications and lymphoedema.
  • Survival rates are significantly influenced by the extent of lymph node involvement.
  • Complete dissection of deep nodes is recommended when inguinal nodes are palpably positive to improve survival outcomes.
