Outcome Measures

Primary Outcomes (2)

  • Safety: adverse events

    The number of adverse events (AE), serious adverse events (SAE) or suspected unexpected adverse reactions (SUSAR) after autologous salivary stem cell transplantation. All possible adverse events will be scored according to the definitions of the Common Toxicity Criteria for Adverse Events version 4.0 (CTCAEv4.0).

    Data for assessing safety will be recorded from day 1 to 365.

  • Feasibility: salivary flow rate

    The salivary flow rate of the remaining submandibular gland will be recorded.

    Data for assessing feasibility will be recorded 6 and 12 months after autologous stem cell transplantation to assess if salivary flow will be increased compared to salivary flow before transplantation.

Secondary Outcomes (6)

  • Salivary flow recovery

    Saliva measurements at 6 and 12 months and then on a yearly basis until 5 years after postoperative (chemo)radiation

  • Impact of transplantation

    Patient-rated outcome measures at 6 and 12 months and then on a yearly basis until 5 years after postoperative (chemo)radiation

  • Locoregional control

    5 years after postoperative (chemo)radiation

  • Overall survival and disease-free survival

    5 years after postoperative (chemo)radiation

  • Rate of water diffusion in remaining submandibular gland

    6 and 12 months after postoperative (chemo)radiation

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Squamous cell carcinoma (SCC) originating from the mucosa of the oral cavity;
  • Primary resection of tumour including an electively or therapeutic ipsilateral neck dissection (at least levels Ib to III, including the submandibular gland).
  • Postoperative radiotherapy or chemoradiation, including prophylactic or therapeutic irradiation of the contralateral side of the neck (where the remaining submandibular gland is), including at least levels Ib to IV), next to irradiation of the tumour bed and ipsilateral neck (current standard);
  • Age ≥ 18 years;
  • WHO performance 0-2;
  • Written informed consent;

You may not qualify if:

  • Primary (definitive) radiotherapy, with or without systemic treatment;
  • Previous radiotherapy of the head and neck region (re-irradiation);
  • Positive microbiological screening for Human Immunodeficiency Virus type 1 and 2, hepatitis B and C virus and Treponema pallidum.
  • Presence of systemic disease known to affect salivary gland functioning (e.g., Sjögren's syndrome);
  • Known allergy to mice and gentamicin
  • History within the past five years of malignancies other than:
  • basal or squamous cell carcinoma of the skin
  • in situ carcinoma of the cervix;
  • Females who are pregnant or lactating at entry.
