Prostate Cancer Clinical Trial
The UPPROACH (Upfront Intensity Modulated Proton Beam Therapy) Approach
Summary
A phase 2 study with the primary objective of testing treatment compliance of Upfront Intensity Modulated Proton Beam Therapy (IMPT) and Concurrent Chemotherapy (UPPROACH) for Post-operative Treatment in Loco-regionally Advanced Endometrial Cancer is non-inferior to the historic compliance rate of the chemoradiation arm of GOG 258 study
Full Description
While there is a consensus that both adjuvant ChT and RT benefit patients with respect to locoregional and distant control, the sequencing of these therapies varies between institutions. Common approaches include sequential treatment, with 4-6 cycles of ChT followed by RT, sandwich therapy with RT sandwiched between 3 cycles of ChT, or concurrent CRT. Small retrospective studies have shown a benefit with respect to PFS and OS in the sandwich approach, however this has not been replicated in larger studies.
In more recent years, proton beam therapy (PBT) has become an increasingly common modality for the treatment of uterine malignancies and is capable of even more precise dose distributions than photon-based RT due to intrinsic properties of these much heavier particles. Dosimetric/planning studies from other institutions confirm the significant reduction of dose to critical normal tissues like bladder, bowel, rectum, and bone marrow.
Preliminary data from the University of Maryland Medical Center has suggested that IMPT using pencil beam scanning is feasible in patients with endometrial cancer, with only 10% of patients developing grade 2 GI toxicity and no patients developing ≥ grade 3 GI or GU toxicities (abstract under review).
The investigators would like to test the hypothesis that in the postoperative setting, patients with advanced endometrial cancer will be able to complete a course of full dose ChT - carboplatin and paclitaxel - concurrent with upfront pelvic IMPT.
Eligibility Criteria
Inclusion Criteria:
Surgery must have included a hysterectomy. Bilateral salpingo-oophorectomy, pelvic lymph node sampling, para-aortic lymph node sampling, and omentectomy are optional
Patients will be staged according to FIGO 2009 staging system. Eligibility is defined based on clinical-pathologic features.
Patients with endometrioid endometrial cancer with the following:
Stage IA grade 3 with extensive LVSI
Stage IB grade 3
Stage II
Stage III (A, B, and C)
Stage IVA who are recommended adjuvant whole pelvic RT (+/- lower para-aortic up to renal hilum) and systemic chemotherapy.
Patients with clear cell, serous papillary carcinoma, or carcinosarcoma with stages IA-III who are recommended adjuvant whole pelvic RT (+/- lower para-aortic up to renal hilum) and systemic chemotherapy.
Patients with a GOG Performance Status of 0, 1, or 2
Patients with adequate organ function, reflected by the following parameters:
WBC ≥ 3000/mcl
Absolute neutrophil count (ANC) ≥ 1000/mcl
Platelet count ≥ 100,000/mcl
SGOT, SGPT, and alkaline phosphatase ≤ 2.5 X upper limit of normal (ULN)
Bilirubin ≤ 1.5 X ULN
Creatinine ≤ institutional ULN (if serum creatinine > ULN, estimated GFR ≥ 45 ml/min)
Patients who have signed an approved informed consent and authorization permitting release of personal health information
Patients must be 18 years of age or older
Exclusion Criteria:
Patients with leiomyosarcoma
Patients with clinically significant pelvic or para-aortic nodal disease, on post-surgery CT scan, that was not dissected and would require higher boost dose
Patients with recurrent endometrial cancer with gross nodal or vaginal disease requiring high dose radiotherapy, or history of prior chemotherapy
Patients with a history of prior pelvic/abdominal RT or with history of prior cancer treatment that contraindicates this protocol therapy including history of prior chemotherapy for any other malignancy.
Patients with a history of serious co-morbid illness or uncontrolled illnesses that would preclude protocol therapy
Patients with an estimated survival of less than three months
Patients with FIGO 2009 Stage IVB endometrial cancer
Patients with a history of myocardial infarction, unstable angina, or uncontrolled arrhythmia within 3 months from enrollment
