The goal of this multicenter, observational, analytic, randomized clinical trial is to analyze the laparoscopic and robot-assisted method in the surgical treatment of patients with adrenal diseases. The main question it aims to answer are:

1. to find the superiority of one the the surgical method mentioned above
2. to compare the quality of life in patients with adrenal mass before surgery and after laparoscopic or robotic-assisted adrenalectomy.

Surgical resection can be performed at the time of study entry, when patients have a mixed response, or if their tumors respond to chemotherapy.

Surgical resection will be followed by chemotherapy with 2 grams oral dose daily of mitotane on cycle 1, day 1, 6 mg/m\^2 continuous intravenous infusion doxorubicin over 96 hours days 1-4, 0.18 mg/m\^2 continuous intravenous infusion vincristine over 96 hours days 1-4, and 36 mg/m\^2 continuous intravenous infusion etoposide over 96 hours days 1-4, and 150 mg tariquidar through central venous catheter over 30 minutes on days 1 and 3.

XR9576 (Tariquidar)

Antonio Fojo, M.D.

This study will examine the safety and effectiveness of treating adrenocortical cancer with combination chemotherapy using doxorubicin, vincristine, and etoposide in addition to the drugs mitotane and tariquidar and, when possible, surgery. Adrenocortical cancer cells have a large amount of a protein called P-glycoprotein that "pumps" anti-cancer drugs out of the cells, decreasing their effectiveness. Continuous infusions of doxorubicin, vincristine, and etoposide may improve chemotherapy results by blocking the P-glycoprotein pump, as may use of tariquidar, an experimental drug that is known to block the P-glycoprotein pump.

Patients 18 years of age and older with adrenocortical cancer that has recurred, spread, or cannot be treated surgically may be eligible for this study. Candidates will be screened with a medical history and physical examination; review of pathology slides; blood tests; electrocardiogram (EKG); imaging tests, including computed tomography (CT) of the chest, abdomen and pelvis; chest x-ray; and possibly a bone scan or other imaging tests needed to evaluate the cancer, urine studies, and an echocardiogram. Also, a biopsy (removal of a small sample of tumor tissue) may be required if a specimen is not available to confirm the cancer.

Participants will undergo the following tests and procedures:

* Tumor biopsy. Before starting chemotherapy, a small piece of tumor is removed to study the P-glycoprotein pump and to determine the tumor genetics.
* Blood draw. Blood is drawn before treatment begins to establish baseline levels for future blood tests.
* Central venous catheter placement. A specially trained physician places a plastic tube into a major vein in the chest. The tube is used to give the study drugs and other medications and to withdraw blood samples. It can stay in the body for months or be removed after each treatment is completed. The tube placement is done under a local anesthetic in the radiology department or operating room.
* Chemotherapy. Treatment cycles are 21 days. Doxorubicin, vincristine, and etoposide are given through the central venous catheter by an infusion pump continuously over 96 hours starting day 1 of each cycle. The dose of these drugs may be increased or decreased from cycle to cycle, based on side effects. Mitotane is given in pill form starting day 1 of cycle 1 and is taken every day throughout the entire study. The mitotane dose is gradually increased as long as the side effects are tolerable. Tariquidar is given through the central venous catheter as a 30-minute infusion on days 1 and 3 of every cycle. The tariquidar dose remains the same throughout the study. Treatment will continue for two cycles after all the cancer is gone, or until surgery is done to remove some or all of the remaining cancer, or, if surgery is not an option, until the cancer has grown to where it is defined as progressive disease.
* Nuclear scans. A nuclear scan is done before treatment begins and again on day 1 or day 3 of the first treatment cycle after administration of tariquidar to evaluate the P glycoprotein response to treatment.
* Computed tomography (CT) scans. These scans are done every two treatment cycles to follow disease progress.
* Surgery. Surgery to remove areas of cancer may be considered at any point during the study (including before beginning treatment), if it is deemed beneficial. Treatment with the study drugs will begin or resume after surgery. The length of treatment will depend on the response to treatment before the surgery and on whether there is any cancer remaining after the surgery.

Adrenocortical cancer (ACC) is a rare tumor that is optimally treated with surgical resection. However, many patients present with unresectable disease and relapses are common after surgical resection creating a need for more effective systemic therapies. Several investigators have reported responses to a variety of chemotherapy agents, without a clear improvement in overall survival. A possible explanation for these disappointing results is the high levels of expression of P-glycoprotein (Pgp) seen in a majority of adrenocortical cancers. Pgp, a membrane protein that can function as a drug efflux pump lowering the intracellular concentrations of various drugs, has been implicated as a mechanism of drug resistance.

A prior National Cancer Institute (NCI) study (referred to as MAVE) tried to improve response rates by using a combined modality approach with chemotherapy and surgery. Prior in vitro studies had shown that mitotane inhibited Pgp and that continuous exposure to doxorubicin and vincristine was more effective at overcoming Pgp-mediated resistance than the same drugs given on an intermittent schedule. The MAVE study used daily oral mitotane with infusional doxorubicin, vincristine, and etoposide prior to tumor resection in patients with resectable or potentially resectable tumors. The results showed an overall response rate of 19% (including minor responses), and an overall median survival of 13.5 months. These results were similar to those reported with previous regimens in adrenocortical cancer (ACC). A possible explanation for the failure to achieve a higher response rate may be that mitotane was unable to inhibit Pgp. Although the serum levels of mitotane achieved in patients had been shown to block Pgp in vitro, inhibition of Pgp in patients was not accomplished, as documented by a validated surrogate assay using Pgp-expressing CD56+ cells and the Pgp substrate, rhodamine. Thus the question of whether Pgp inhibition would improve response rates remains unanswered.

This trial will attempt to answer the latter question by using an agent, tariquidar (XR9576), which has been proven to inhibit Pgp in humans with minimal toxicity alone or in combination with chemotherapy. Tariquidar will be used with the regimen from the prior MAVE study in an effort to improve response rates and overall survival in patients with ACC whose options at this time are limited.

Surgery Plus Chemotherapy (Doxorubicin, Vincristine and Etoposide), Mitotane, and Tariquidar to Treat Adrenocortical Cancer

A Study of Combination Chemotherapy & Surgical Resection in the Tx of Adrenocortical Cancer: Mitotane & Continuous Infusion Doxorubicin, Vincristine & Etoposide w/the P-glycoprotein Antagonist, Tariquidar (XR9576), Before & After Surgical Resection

Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Complete response is defined as the disappearance of all signs and symptoms of tumor for a period of at least 4 weeks. Partial response is defined as at least a 30% decrease in the sum of the longest diameter of all measured lesions lasting for a period of 4 weeks.

Here is the number of participants with adverse events. For the detailed list of adverse events see the adverse event module.
