Neoadjuvant RCT Versus CT for Patients With Locally Advanced, Potentially Resectable Adenocarcinoma of the GEJ

Korábbi kezelés

• Past or current history (within the last 5 years prior to treatment start) of other malignancies. Patients with curatively treated basal and squamous cell carcinoma of the skin or in situ carcinoma of the cervix are eligible
• Patients medically unfit for chemotherapy and radiotherapy
• Patients receiving any immunotherapy, cytotoxic chemotherapy or radiotherapy other than defined by the protocol. The participation in another clinical trial with the use of investigational agents, chemotherapy or radiotherapy during the trial is not permitted

Más betegség

• Evidence of metastatic disease (exclusion of distant metastasis by CT of thorax and abdomen, bone scan or MRI [if osseous lesions are suspected due to clinical signs])
• Patients with other significant underlying medical conditions that may be aggravated by the study treatment or are not controlled
• Known hypersensitivity against 5-FU, folinc acid, oxaliplatin or docetaxel
• Clinically significant active coronary heart disease, cardiomyopathy or congestive heart failure, NYHA III-IV
• Other severe internal disease or acute infection
• Chronic inflammatory bowel disease

Egyéb

• Evidence of peripheral sensory neuropathy > grade 1 according to CTCAE version 4.03
• Pregnant or lactating females
• Other known contraindications against 5-FU, folinic acid, oxaliplatin, or docetaxel
• Clinically significant valvular defect
• Peripheral polyneuropathy > NCI Grade II according to CTCAE version 4.03

• Histologically proven, locally advanced and potentially resectable adenocarcinoma of the gastroesophageal junction (GEJ) (Siewert I- III) that is: cT3-4, any N, M0 or cT2 N+, M0 according to AJCC 8th edition
• Patients* must be candidates for potential curative resection as determined by the treating surgeon
• ECOG performance status 0-1
• Age 18 years or above
• Adequate hematologic function with absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/l, platelets ≥ 100 x 10\^9/l and hemoglobin ≥ 9.0 mg/dl
• INR <1.5 and aPTT<1.5 x upper limit of normal (ULN) within 7 days prior to randomization
• Adequate liver function as measured by serum transaminases (ASAT, ALAT) ≤ 2.5 x ULN and total bilirubin ≤ 1.5 x ULN
• Adequate renal function with serum creatinine ≤ 1.5 x ULN
• QTc interval (Bazett*) ≤ 440 ms
• Written informed consent obtained before randomization
• Negative pregnancy test for women of childbearing potential within 7 days of commencing study treatment. Males and females of reproductive potential must agree to practice highly effective*** contraceptive measures during the study and for 6 months after the end of study treatment. Male patients must also agree to refrain from father a child during treatment and up to 6 months afterwards and additionally to use a condom during treatment period. Their female partner of childbearing potential must also agree to use an adequate contraceptive measure.
  • *There are no data that indicate special gender distribution. Therefore, patients will be enrolled in the study gender-independently.
  • ** formula for QTc interval calculation (Bazett): QTc= ((QT) ̅" (ms)" )/√(RR (sec))= ((QT) ̅" (ms)" )/√(60/(Frequence (1/min)))
  • *** highly effective (i.e. failure rate of <1% per year when used consistently and correctly) methods: intravaginal and transdermal combined (estrogen and progestogen containing) hormonal contraception; injectable and implantable progestogen-only hormonal contraception; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomised partner; sexual abstinence (complete abstinence is defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments).
