Brief Summary

Oropharyngeal squamous cell carcinoma (OPSCC) is now the most frequently diagnosed head and neck cancer in Denmark which is mainly due to the increase of Human Papillomavirus (HPV). Patients with HPV-positive OPSCC have a significantly higher survival rate compared to HPV-negative OPSCC. The traditional primary treatment modality in Denmark is Intensity Modulated Radiation Therapy (IMRT), and in advanced stages in combination with chemotherapy. Since 2009, Transoral Robotic Surgery (TORS) has enabled surgeons to perform minimally invasive surgery as an alternative to standard radiotherapy treatment which is considered the primary treatment for OPSCC in many countries. There is a lack of randomised trials comparing long-term functional outcomes after TORS or IMRT. Current data are mostly derived from retrospective studies with selection bias. However, several small retrospective studies have shown promising results when comparing the two treatment modalities in favour of TORS with regards to treatment related swallowing function and quality of life (QoL) without compromising survival outcomes. This study aims to evaluate the early and long-term functional outcomes following two treatment arms 1) TORS combined with neck dissection and 2) IMRT±concurrent chemotherapy with a special focus on swallowing-related QoL.

Outcome Measures

Primary Outcomes (1)

  • Swallowing related quality of life by MDADI

    Difference in swallowing related quality of life measured by a composite MD Anderson Dysphagia Inventory (MDADI) score. The MDADI is a 20-item self-administered questionnaire that quantifies swallowing-related quality of life. Each item is scored on a 5 point Likert scale (strongly disagree, disagree, no opinion, agree, strongly agree). The composite MDADI score summarizes overall performance on remaining 19-items of the MDADI, as a weighted average of the physical, emotional, and functional subscale questions. Summary and subscale MDADI scores are normalized to range from 20 (extremely low functioning) to 100 (high functioning).

    evaluated at baseline, 3 and 12 months after treatment

Secondary Outcomes (16)

  • Nasogastric or percutaneus tube dependency

    evaluated at baseline, 3 and 12 months after treatment

  • Swallowing function by fiberendoscopic evaluation

    evaluated at baseline, 3 and 12 months after treatment

  • Swallowing function by modified barium swallowing

    evaluated at baseline, 3 and 12 months after treatment

  • Patient reported quality of life by EORTC-QLQ-H&N35

    evaluated at baseline, 3 and 12 months after treatment

  • Patient reported quality of life by EORTC QLQ-C30

    evaluated at baseline, 3 and 12 months after treatment

  • +11 more secondary outcomes

Study Arms (2)

Transoral robotic surgery (TORS)

EXPERIMENTAL
Procedure: Transoral Robotic Surgery (TORS) with neck dissection

Intensity-Modulated Radiation Therapy (IMRT)

ACTIVE COMPARATOR

Patients with clinical T1N0 stage are offered accelerated radiotherapy to 66 Gy/33fractions with concurrent nimorazole. Patients with clinical T2N0 stage are offered either accelerated radiotherapy to 66 Gy/33fractions with the option of weekly cisplatin to fit patients or hyper-fractionated accelerated radiotherapy to 76 Gy/56fractions both with concurrent nimorazole. Patients with clinical T1-T2, N1 stage are offered accelerated radiotherapy to 66 Gy/33 fractions and nimorazole with the addition of concurrent weekly cisplatin 40 mg/sqm to fit patients.

Radiation: Intensity-Modulated Radiation Therapy (IMRT)Drug: CisplatinDrug: Nimorazole.

Interventions

Robotic-assisted resection of the primary oropharyngeal tumour and ipsilateral selected neck dissection of lymph node levels II-IV. Patients with a primary base of tongue cancer or with significant involvement of tongue base or the soft palate defined as above 1 cm, will be offered a bilateral neck dissection of levels II-IV.
