About this study

Official title: A Pilot Phase II Trial of Radiation Therapy "Sandwiched" Between Paclitaxel and Carboplatin in Patients With Uterine Papillary Serous Carcinoma

Combination chemo/radiotherapy trials in advanced/recurrent endometrial cancer are ongoing. The optimal radiation modality, chemotherapeutic agents, and sequence of these regimens for the treatment of UPSC are yet to be established. A retrospective review of 16 patients treated at our institution with the sequential use of radiation "sandwiched" between paclitaxel/platinum chemotherapy found only one patient to have recurred at 16 months with a median follow-up of 15 months (range 6-33 months). The regimen was well tolerated. Eight of the sixteen patients (50%) developed grade 3 neutropenia following cycle 4 of chemotherapy, two of which required a 1 week treatment delay. There were no cases of grade 3 or 4 thrombocytopenia noted. There was no febrile neutropenia and no hospital admissions for toxicity. There were no observed grade 3 or 4 non-hematologic toxicities. With the median follow up of 15 months, we have not observed late toxicities.

Given these favorable preliminary findings, supported by recently published data documenting efficacy of the "sandwich" multimodality technique in other difficult uterine malignancies (malignant mixed mullerian tumors), we propose to study this combination of chemotherapy and radiation prospectively. Our aim is to better evaluate patterns of recurrence and possible benefits in progression-free and overall survival.

Read the detailed description

Uterine papillary serous carcinoma (UPSC) is an uncommon, but aggressive variant of endometrial carcinoma that has a high recurrence rate and poor response to therapy. It has a propensity to metastasize throughout the abdomen, similar to serous carcinoma of the ovary. In fact, many patients with disease apparently confined to the uterus have microscopic intra-abdominal spread at the time of diagnosis. Recurrences are common both in the pelvis as well as in the upper abdomen.

After staging and debulking of gross disease, adjuvant radiation therapy is recommended to treat patients with endometrial carcinoma at high risk for recurrent disease. High-risk features include histologic cell type, grade, depth of myometrial invasion, cervical extension, lymph-vascular invasion, adnexal involvement, intraperitoneal spread, positive peritoneal cytology, and positive lymph nodes. Pelvic radiation can limit local recurrences to less than 6.5%. However, approximately 25-30% of patients with high-risk features who receive radiation recur with distant metastases. Even patients treated with whole abdominal irradiation are at risk for extra-abdominal recurrences with progression-free intervals of 7 to 8 months.

Adjuvant chemotherapeutic regimens have been studied in high-risk endometrial cancers, but none have demonstrated a survival advantage. Doxorubicin, in combination with platinum, has a reported 42% response rate, but a high toxicity profile. Paclitaxel has an overall response rate of 36% in patients with advanced and recurrent endometrial cancer. Platinum-based chemotherapies have a 28-42% response rate.

Retrospective studies in patients with UPSC have demonstrated response rates of up to 35% in patients with multiagent chemotherapy. In one study, a median progression-free interval of 30 months was observed in patients treated with paclitaxel and platinum in the adjuvant and recurrent settings. Based on these findings and the similarities and clinical success of paclitaxel/platinum therapy in patients with ovarian serous carcinoma, this combination warrants further investigation in a prospective manner in patients with UPSC.

Combination chemo/radiotherapy trials in advanced/recurrent endometrial cancer are ongoing. The optimal radiation modality, chemotherapeutic agents, and sequence of these regimens for the treatment of UPSC are yet to be established. A retrospective review of 16 patients treated at our institution with the sequential use of radiation "sandwiched" between paclitaxel/platinum chemotherapy found only one patient to have recurred at 16 months with a median follow-up of 15 months (range 6-33 months). The regimen was well tolerated. Eight of the sixteen patients (50%) developed grade 3 neutropenia following cycle 4 of chemotherapy, two of which required a 1 week treatment delay. There were no cases of grade 3 or 4 thrombocytopenia noted. There was no febrile neutropenia and no hospital admissions for toxicity. There were no observed grade 3 or 4 non-hematologic toxicities. With the median follow up of 15 months, we have not observed late toxicities.

Given these favorable preliminary findings, supported by recently published data documenting efficacy of the "sandwich" multimodality technique in other difficult uterine malignancies (malignant mixed mullerian tumors), we propose to study this combination of chemotherapy and radiation prospectively. Our aim is to better evaluate patterns of recurrence and possible benefits in progression-free and overall survival.

Surrogate endpoint biomarkers such as ER/PR, HER2/Neu and p53 will be correlated with prognosis. In addition, fresh frozen tissue will be banked for future cDNA microarray analyses of UPSC tumors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To Evaluate the Toxicity and Tolerability of Pelvic Radiation "Sandwiched" Between Cycles of Paclitaxel/Carboplatin Chemotherapy in Patients With UPSC

    Overall survival analysis of early stage (stage 1 \& 2) and late stage (stage 3 \& 4)UPSC patients who were prescribed radiation "sanwhiched" between three cycles of paclitaxel/platinum chemotherapy before and after RT. Outcome measures were Progression Free Survival (PFS) and Overall Survival (OS).

    Measured: Up to 7 years

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Aug 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To Evaluate the Toxicity and Tolerability of Pelvic Radiation "Sandwiched" Between Cycles of Paclitaxel/Carboplatin Chemotherapy in Patients With UPSC (time frame: Up to 7 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00231868, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2020.
