Surgery and Heated Intraperitoneal Chemotherapy for Adrenocortical Carcinoma

Adrenocortical carcinoma (ACC) is an exceptionally rare tumor with a very poor prognosis. The best treatment of these tumors is surgical resection, and repeat operations if the tumors recur. For tumors that cannot be resected, a few drugs given intravenously exist to help slow the progression of the disease. Cisplatin given intravenously is among the most effective drugs for ACC. In studies of other tumor types, heated Cisplatin administered directly into the abdomen at the time of surgery to remove all visible tumor deposits has been shown to effectively treat the tumor over surgery alone or drugs being given intravenously. The purpose of this study is to better understand if surgical resection of all visible disease with intraperitoneal administration of heated cisplatin can improve outcomes from metastatic ACC. Additionally, the investigators would like to understand associated complications, how quality of life is affected, and if there are specific tumor factors that affect survival and recurrence after this procedure. To be eligible for the study, participants must have ACC that can be seen on CT imaging. A surgeon must believe the disease can be safely removed, and that the patient can tolerate the operation and potential complications. Patients who are successfully debulked of visible tumor will undergo heated intra-abdominal chemotherapy with Cisplatin at the same operation. Associate investigators in coordination with the Principal Investigator will evaluate patients over 18 years of age for eligibility. This investigation aims to improve quality and length of life in patients with limited options for the treatment of metastatic ACC.

• Cisplatin (Drug), also known as Platinol: Route of administration: Intraperitoneal for tumor treatment. Dose of 250 mg/m2 Drug 1 of the hyperthermic intraperitoneal chemotherapy (HIPEC)
• Sodium thiosulfate (Drug), also known as Sodium thiosulfate injection: Route of administration: Intravenous Loading dose of 7.5 gm/m2 over 20 minutes followed by 2.13 gm/m2/hr for 12 hours Drug 2 given intravenously during hyperthermic intraperitoneal chemotherapy (HIPEC)
• Cytoreductive surgery (Procedure), also known as Cytoreductive debulking surgery: Standard of care: Surgical procedure used to remove tumors from patients with peritoneal tumors.

Primary outcomes

• Progression Free Survival [Up to 5 years]: The length of time after optimal debulking and heated intraperitoneal chemotherapy that a patient lives before there is clinical evidence of recurrent adrenocortical cancer.

Secondary outcomes

• Morbidity Rate [Up to 5 years]: The frequency of post-operative complications.
• Quality of Life (QOL) Score [Up to 5 years]: This measures the impact of surgery and HIPEC on quality of life.
• Overall Survival [Up to 5 years]: The length of time people are alive after surgery and HIPEC for adrenocortical cancer.

Sex: All, ages: 18 Years to 99 Years

INCLUSION CRITERIA

* Histologically proven ACC with the majority of disease confined to the peritoneal cavity and resectable or amenable to radiofrequency ablation
* Disease evaluable by CT or Positron Emission Tomography (PET) imaging
* All disease should be deemed resectable based on imaging studies e.g.:

  * Hepatic metastases (unilateral or bilateral less than or equal to 5 lesions, less than or equal to 15 cm total diameter)
  * Note: Hepatic lesions must be amenable to complete resection
  * Primary peritoneal metastases (small disease load less than or equal to P2 disease) without massive ascites or intestinal obstruction
  * Lung metastases (less than or equal to 3 unilateral/bilateral, 9 cm total diameter)
  * Note: lung lesions must be amenable to complete resection
  * Note: Patients with both pulmonary and hepatic metastases will be enrolled at the discretion of the PI
  * Note: In situations where resection to Completeness of Cytoreduction Score (CC) 0 or 1 is uncertain, patients may undergo diagnostic laparoscopy prior to enrollment to determine feasibility of resection.
* Greater than or equal to 18 years of age
* Able to understand and sign the Informed Consent Document
* Clinical performance status of Eastern Cooperative Oncology Group (ECOG) less than or equal to 2
* Life expectancy of greater than three months
* Patients of both genders must be willing to practice birth control during and for four months after receiving chemotherapy
* Hematology:

  * Absolute neutrophil count greater than 1500/mm\^3 without the support of Filgrastim.
  * Platelet count greater than 75,000/mm\^3.
  * Hemoglobin greater than 8.0 g/dl.
* Chemistry:

  * Serum creatinine less than or equal to 1.5 mg/dl unless the measured creatinine clearance is greater than 60 mL/min/1.73 m2
  * serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) within 5 times the upper limit of normal and a total serum bilirubin of less than 3 times the upper limit of normal, both of which define the upper limit of grade 2 treatment related toxicities.
  * Prothrombin time (PT) within 2 seconds of the upper limit of normal (INR less than or equal to 1.8)
* Recovered from any toxicity to grade 2 or less from all prior chemotherapy, immunotherapy or radiotherapy and be at least 30 days past the date of their last treatment with the exception of mitotane which may be continued.
* Able to understand their disease and the exploratory nature of combining surgery and HIPEC for this histology.

EXCLUSION CRITERIA

* Concomitant medical problems that would place the patient at unacceptable risk for a major surgical procedure.
* History of congestive heart failure and/or an left ventricular ejection fraction (LVEF) less than 40%

Note: Patients at increased risk for coronary artery disease or cardiac dysfunction (e.g., greater than 65yo, diabetes, history of hypertension, elevated LDL, first degree relative with coronary artery disease) will undergo full cardiac evaluation and will not be eligible if they demonstrate significant irreversible ischemia on stress thallium or an ejection fraction less than 40%.

\- Significant chronic obstructive pulmonary disease (COPD) or other chronic pulmonary restrictive disease with pulmonary function test (PFT) indicating an forced expiratory volume at one second (FEV1) less than 50% or a diffusing capacity of lung for carbon monoxide (DLCO) less than 40% predicted for age.

Note: Patients who have shortness of breath with minimal exertion or who are at risk for pulmonary disease (e.g., chronic smokers) will undergo pulmonary function testing and will not be eligible if their FEV1 is less than 50% of expected.

* Grade 2 or greater neuropathy
* Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the chemotherapy on the fetus or infant.
