Summary

The present monocentric prospective phase 2 study aims to reproduce the results obtained at NIRS thus offering the possibility of obtaining a promising rate of progression-free survival (PFS) and local control (LC) in patients diagnosed with mucosal melanoma of lower genital tract. Systemic treatment with immunotherapy is not the subject of this study but is allowed both in the neoadjuvant and sequential regimens.

Melanomas have always been considered poorly radiosensitive. It is now accepted that high LET (Linear Energy Transfer) particle beams, such as carbon ions, can offer a biological advantage, compared to photons treatment, in radio-resistant neoplasms treatment, thanks to their higher biological efficacy (RBE) against tumours with a low α/ ß ratio. In addition, carbon ions have the physical advantage of an inverted depth deposition profile compared to photons, allowing then a steep dose gradients that ensure increased sparing of adjacent healthy organs at risk (OARs).

Conditions

  • Malignant Melanoma
  • Gynecologic Cancer

Interventions

RADIATION

carbon ion radiation therapy CIRT

CIRT: The low-dose CTV (clinical target volume) will receive a total dose of 43 GyRBE in 10 fractions, 4 fractions per week. The high-dose CTV will receive a total dose of 68.8 GyRBE in 16 fractions, 4 fractions per week. The expected duration of treatment is 4 weeks, 4 fractions per week. Treatments lasting longer than 6 weeks, or with less than 6 fractions administered on 14 consecutive days, will not be considered acceptable. Immunotherapy: Patients will undergo immunotherapy after carbon ion radiation therapy (CIRT) up to maximum response and/or up to tolerance. The concomitant association of immunotherapy is not envisaged in this protocol.
