Clinical Trial Summary

Despite developments in the multidisciplinary treatment of patients with locally advanced rectal cancer (LARC), such as the introduction of total mesorectal excision (TME) by Heald et al. and the shift from adjuvant to neoadjuvant (chemo)radiotherapy ((C)RT), local and distant recurrence rates remain between 5-10% and 25-40% respectively. Several studies established tumour characteristics with particularly bad prognosis; it was demonstrated that the occurrence of mesorectal fascia involvement (MRF+), grade 4 extramural venous invasion (EMVI), tumour deposits (TD) and enlarged lateral lymph nodes (LLN) lead to high local and distant recurrence rates and decreased survival when compared with LARC without these particularly negative prognostic factors. This type of LARC is described as high risk LARC (hr-LARC). Achieving a resection with clear resection margins (R0) is an important prognostic factor for local (LR) and distant recurrence (DM) as well as survival. With the aim to further reduce the risk of recurrent rectal cancer, to diminish distant metastasis and to improve overall survival for patients with LARC, induction chemotherapy (ICT) became a growing area of research. The addition of ICT has the ability to induce more local tumour downstaging, possibly leading to resectability of previously unresectable tumours, more R0 resections and less extensive surgery. In the case of a complete clinical response, surgery may even be omitted. ICT may also have the potential to eradicate micrometastases. Hence, increased local downstaging and reducing distant metastatic spread may reduce LR and DM rates and improve survival and quality of life. In recent years, the use of ICT was investigated and showed promising results, but little is known about the addition of ICT in patients with high risk LARC. Since these patients have a particularly bad prognosis, both with regard to locoregional and distant failure, a more intensified neoadjuvant treatment with FOLFOXIRI is anticipated to improve short- and long term results.

Intervention

Drug:
• FOLFOXIRI Protocol
FOLFOXIRI consists of oxaliplatin, irinotecan, leucovorin and 5-fluorouracil and is administered every 2 weeks: Dosing: Day 1: irinotecan 165 mg/m2 body-surface area (BSA) intravenously (IV), followed by oxaliplatin 85mg/m2 BSA IV in combination with leucovorin 400mg/m2 BSA, followed by: Day 1-2: 3200 mg/m2 BSA of continuous 5-fluorouracil IV Day 3-14: rest days. Both regimen are initially administered for four cycles. In case of responsive or stable disease, a 5th and 6th cycle of FOLFOXIRI will be administered. In case of unacceptable toxicity, the aforementioned dosages can be reduced or one or more chemotherapeutical agents can be omitted at discretion of the medical oncologist and will be noted in the patient's medical file. At discretion of the medical oncologist, a start dosage of 75% of the advised dosage could be considered in patients above 70 years of age.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The main study parameter is the proportion of patients with a pathological complete response (pCR) and those patients who started a wait and see strategy and have sustained clinical complete response (cCR) at 1 year.	The pCR is evaluated by an experienced pathologist. A pCR is defined as the absence of residual tumour cells in the complete resected specimen including all resected regional lymph nodes (ypT0N0). A cCR is defined as the absence of viable tumour tissue based on MRI, evaluated by an experienced radiologist. There is a cCR in case of a sustained clinical response at 1 year after chemoradiotherapy.	pCR is determined after surgery directly. There is a cCR in case of a sustained clinical response until at least one year after chemoradiotherapy
Secondary	3-year and 5-year local recurrence free survival.	ocal recurrence is confirmed by either radiological or histopathological examination. A recurrence is registered by the treating physician in the patient's medical file.	3 and 5 year
Secondary	3-year and 5-year distant metastasis free survival.	Distant metastases may be confirmed by either radiological or histopathological examination. Data on distant metastases are registered by the treating physician in the patient's medical file.	3 and 5 year
Secondary	3-year and 5-year progression free survival.	Progression is defined as progression of the primary tumour, local recurrence, distant metastases confirmed by radiological or histopathological examination or death. Data regarding disease progression are registered by the treating physician in the patient's medical file.	3 and 5 year
Secondary	3-year and 5-year disease free survival.	Disease free survival is defined as no confirmed recurrence, distant metastases or death. Disease recurrence is registered by the treating physician in the patient's medical file.	3 and 5 year
Secondary	3-year and 5-year overall survival.	Mortality is registered in the patient's medical file which is linked to the municipal personal records database.	3 and 5 year
