Eksperimentel: Radiotherapy plus Tom-Ox
Patients received concomitant boost RT (55 Gy/5 weeks) with concurrent Tom-Ox chemotherapy.
The concurrent chemotherapy consisted of 15 min intravenous infusion Raltitrexed (Tomudex ®) 3 mg/m2 and a two-hours intravenous infusion of Oxaliplatin (Eloxatin ®) at 130 mg/m 2, 20 min after raltitrexed, on days 1, 17, 35.
|
Radiotherapy was applied as conformal 3-D technique and was delivered with photon energies of 10 - 15 MV.
The beams were delivered by an Elekta Precise Linac equipped with standard multi leaf collimators (MLC).
A daily online check of isocenter position was performed using portal imaging, with set-up correction in case of displacement > 0.5 cm in any direction.
Radiation dose delivered to PTV2 was 45 Gy (1.8 Gy/fraction) with a concomitant boost dose to the PTV1 of 10 Gy with accelerated fractionation at 2.2 Gy/fraction, five consecutive days for week.
The concurrent chemotherapy consisted of 15 min intravenous infusion Raltitrexed (Tomudex ®) 3 mg/m2 and a two-hours intravenous infusion of Oxaliplatin (Eloxatin ®) at 130 mg/m 2, 20 min after raltitrexed, on days 1, 17, 35.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Number of patients defined as good responders (G1 or G2) according to the Mandard regression grading system.
Tidsramme: 8 weeks after chemo-radiotherapy
|
Pathologic responses of the primary tumours were defined according to the Mandard regression grading system: grade 1 was recorded when no tumour cells remained in the primary tumour and lymph nodes (pCR); grade 2 was characterized by the presence of rare residual cancer cells scattered through the fibrosis; grade 3 was characterized by an increase in the number of residual cancer cells, but fibrosis still predominated; grade 4 showed residual cancer outgrowing fibrosis; and grade 5 was characterized by an absence of regressive changes.
Good responders were defined those patients with a pathologic response with Mandard G1 or G2 and poor responder patients with Mandard G3, G4 or G5.
