FOLFOXIRI With or Without Intensification for Rectal Cancer

Korábbi kezelés

• Endoscope unable to pass through the tumour's lumen plus worsening local obstructive symptoms. Note: Patients with such features should be assessed by the surgical team regarding stomal bypass prior to study enrolment. Such patients can still be considered for study enrolment after undergoing stomal bypass.
• Known peripheral neuropathy of grade 2 or more in severity.\\ -Patients who have received an experimental anticancer therapy within the last 28 days.
• Previous pelvic radiotherapy
• Previous oxaliplatin or irinotecan for the treatment of colon or rectal cancer.
• Major surgery (i.e. requiring general anaesthetics) within the last 28 days. Exception: Any patient who underwent stomal bypass for obstructing primary tumour within the last 14 days are still eligible, as long as the patient has sufficiently recovered from the surgery at the investigator's discretion.
• Patients on warfarin therapy. Patients on low molecular weight heparin are not excluded.

Más betegség

• History of another invasive malignancy within the last 5 years, except for treated basal cell carcinoma of the skin, cervical intraepithelial neoplasia, or breast DCIS.
• Upper rectal cancer that is located above the peritoneal reflection.
• Patients with synchronous colon and rectal cancers are not excluded as long as: (1) these tumors are considered as two separate primaries (i.e. not metastasis or a contiguous part of a large primary), (2) both tumors are not causing imminent obstruction; (3) pelvic radiotherapy is not considered a contraindication.
• Known hypersensitivity reaction to the study drugs (i.e. fluoropyrimidine, irinotecan, oxaliplatin)
• Known cardiac disease that is symptomatic or poorly controlled, including cardiac failure, arrhythmia or ischemic heart disease.
• Myocardial infarction or cerebrovascular accident within the last 12 months.
• Intercurrent infections or medical illnesses that are serious/ potentially life-threatening and require ongoing treatment.
• Patients who refuse surgical treatment of the rectal cancer.

Laborértékek

• Patients with known and untreated bilateral hydronephrosis and/or hydroureters (or unilateral hydronephrosis and/or hydroureters in any patient with a single kidney) are excluded. The obstruction should be treated with ureteric stent(s) or percutaneous nephrostomy(s) prior to study enrolment. Patients with unilateral hydronephrosis and/or hydroureters and adequate renal function (i.e. as stated in the eligibility criteria: serum creatinine level \< 1.5 x ULN, or calculated creatinine clearance \>=50 ml/min - whichever is worse) are not excluded.

Egyéb

• Known distant metastasis, even if the metastasis has been resected.
• Primary tumour associated with any one of the following features:Frank intestinal obstruction, or
• Patient with hip prosthesis
• Patients who are unable to take capecitabine tablets uncrushed by the oral route (e.g. enteral feeding). Patients with significantly impaired gastrointestinal integrity and absorption are excluded.
• Pregnant or lactating women.
• Patients with reproductive potential who are not willing to use barrier method of birth control.
• Patients who are unable to provide written informed consent, or to comply with study requirements as judged by the investigator.

• Able to provide written informed consent
• Age \>= 18 years of either sex.
• ECOG performance status 0-1
• Measurable disease by RECIST 1.1 criteria.
• Histologically confirmed rectal adenocarcinoma (defined as either mid- or low rectal cancer that is located within 12 cm from the anal verge OR below the peritoneal reflection) that is previously untreated.
• 'High risk' rectal cancer, or rectal cancers that are considered marginally perable where there is a significant risk of positive surgical margin:
• T3 or T4, and / or
• Tumour infiltrating perirectal fat and/ or mesorectal fascia, and / or Involvement of pelvic lymph nodes, and/or
• Tumour invading surrounding structures or peritoneum or vasculature.
• Adequate bone marrow, renal and hepatic function as defined by: absolute neutrophil count \>= 1.5 x 109/L, hemoglobin \>= 9 g/L, platelets \>= 100 x 109/L, serum creatinine level \< 1.5 x ULN (or calculated creatinine clearance \>=50 ml/min, whichever is worse), total bilirubin \<=1.5 x the upper limit of normal, alanine aminotransferase (ALT) \< 3 upper limit of normal.
