Acinic Cell Carcinoma Sample Collection


Objectives

  1. To provide a repository for long term storage of acinic cell carcinoma samples and serum. This material will be used in future studies to better understand the molecular biology of acinic cell carcinoma.
  2. To make available, through the Comprehensive Cancer Center of Wake Forest University (CCCWFU) Tumor Tissue Core Laboratory, tumor tissue and serum for proposed projects conducted by IRB approved investigators.

After the necessary specimens for diagnosis and local institutional research are met, the remaining tissue should be considered usable for this project. The patient can be either pre-treatment or post-treatment. When available, adjacent normal and tumor samples should be collected. One half of a cubic centimeter of each should be collected.

Tissue Sample

  1. OR Path Lab will be notified when a patient is enrolled in the study. Tissue is to be kept fresh and not put into fixative.
  2. A special messenger should bring the specimen to the OR Path Lab as soon as possible. It may be appropriate to hold occasional meetings of surgical, laboratory, and clinical personnel to emphasize the urgency of processing these specimens as quickly as possible.
  3. The tissues for submission to the tumor tissue bank should be clean and as free from necrosis as possible.
  4. The tissue should be snap frozen. Place 1 to 5 grams of tissue on a piece of foil, wrap so the specimen is completely covered and immersed in liquid nitrogen. If access to liquid nitrogen is not available immerse the specimens in cold isopentane. Place each foil-wrapped piece in an appropriately lableled baggie. Include on the label the sample code (see below) and whether or not the sample is primary, metastatic, or normal tissue. Store these specimens in either liquid nitrogen or –70oC freezer until ready to ship to CCCWFU Tumor Tissue Core Laboratory.

Buffy Coat Preparation

There are several ways to collect this layer and the method used by your particular lab is probably fine. For both buffy coat and serum, blood is usually obtained from a antecubital vein after the brachial area of the arm is rubbed with an isopropyl alcohol swab. Venipuncture is performed by using a 20 gauge needle and 10 cc of blood is colleted into Vacutainer tubes and immediately placed on ice.

  1. Collect 10 cc of whole blood in a heparinized tube.
  2. Place 1 cc into each of 10 Wintrop glass sedimentation tubes using a 9” Dispo pipette.
  3. Place the Wintrop tubes into centrifuge tubes and spin at 1500 rpm for 5 minutes.
  4. Collect and combine plasma in a cryovial, using a Dispo pipette, and then carefully draw off the white blood cell layer, known as the buffy coat, with a pipette.
  5. These cells should be transferred to a cryovial that’s labeled with the sample code (see below) Then snap freeze the vials in liquid nitrogen and store frozen.

Serum Collection

  1. Blood is colleted into red top Vacutainer tubes and immediately placed on ice. The time the blood was drawn and whether the patient was fasting is recorded.
  2. The tubes of blood are allowed to sit at room temperature for 10 to 15 minutes prior to processing. Blood samples are spun at 4oC for 10 minutes at 2500 rpm.
  3. Serum is removed and 1 ml aliquots are dispensed into cryovials.
  4. Each vial should be clearly marked with the sample code. Store the serum at –70oC until shipment.

Telephone Registration

As soon as a tumor specimen is likely to be available for the Tumor Tissue Bank, call 336-716-3721 to register the specimen. A sample number will be given and should be written on all samples sent. Also necessary are the patient’s name, date of surgery, surgical pathology number, patient’s date of birth. The CCCWFU Tumor Tissue Core Laboratory is open from 8:30 am to 5:30 pm, Monday through Friday, and our voice mail is on at all other times. Prior notification of a specimen shipment will guarantee that personnel are available to receive and process the tissue.

Mailing Instructions

Always call the CCCWFU Tumor Tissue Core Laboratory (336) 716-3721 prior to sending any specimens and to notify the lab of the shipment.

  1. The snap frozen tissue, buffy coat, plasma, and serum samples must be sent on dry ice. Using approximately 4 lbs. Total, layer _ the dry ice on the bottom of the compartment, add the specimens, then fill with the remaining dry ice.
  2. Seal the kit securely with filament or other durable sealing tape.
  3. Arrange for Federal Express pick-up through your usual institutional procedure.


Send the tissue to: Comprehensive Cancer Center of Wake Forest University, c/o Gilda Saluta, Hanes 4032, Medical Center Blvd., Winston-Salem, NC 27157.

If there are any questions call Dr. Greg Kucera, Director of the CCCWFU Tumor Tissue Core Laboratory, (336)-716-6348.
