Cooling Caps in Chemotherapy

As far as the Cancer treatment is concerned, the most widely known treatment be Chemotherapy. Even though we have many advancements in Cancer treatments, Chemotherapy be the ideal one in most of the cases. The major side effect that people face while undergoing Chemotherapy is hair loss. To minimize this, FDA has approved Cooling Caps that can be used during the treatment in order to reduce hair loss. So, let’s have a look at what Cooling caps are?
So, What are Cooling Caps?
Cooling Caps are devices that are designed to reduce hair loss in people who undergo Chemotherapy as a part of their Cancer treatment. FDA initially cleared the device, the DigniCap® Scalp Cooling System, for patients with breast cancer in 2015.
How does it work?
Scalp cooling has been in use in Europe for several decades where it is thought to prevent hair loss by reducing the blood flow to hair follicles. Cooling the scalp causes the blood vessels to constrict, which may limit the amount of chemotherapy drug that reaches the hair follicles.
Cold caps and scalp cooling systems are tightly fitting, strap-on, helmet-type hats filled with a gel coolant that’s chilled to between -15 to -40 degrees Fahrenheit. These caps are worn for 20 to 50 minutes before, during and after the treatment. Cold caps and scalp cooling systems are slightly different. Cold caps are similar to ice packs. Kept in a special freezer before they’re worn, cold caps thaw out during a chemotherapy infusion session and need to be replaced with a new cap about every 30 minutes. With scalp cooling systems, the cap is attached to a small refrigeration machine that circulates coolant, so the cap only has to be fitted once and doesn’t need to changed during chemotherapy. However, the usage and cost depends on the duration of treatment.
The DigniCap System approved by FDA uses a tightly fitted cap in which cold liquid circulates to cool the scalp before, during, and after chemotherapy. This cap, which is connected to a machine that regulates the cooling process, is covered by an outer cap, made of neoprene, that acts as an insulator.
People who use Cooling Caps are generally asked to follow the below provided:
  • no blow drying, hot rollers, or straightening irons
  • shampoo only every third day with cool water and a gentle shampoo
  • no coloring until 3 months after chemotherapy is done
  • gentle combing and brushing

Gamma T Cells and Cancer

Gammadelta T cells (γδ T cells) are T cells that express a unique T-cell receptor (TCR) composed of one γ-chain and one δ-chain. Gammadelta T cells are of low abundance in the body, are found in the gut mucosa, skin, lungs and uterus, and are involved in the initiation and propagation of immune responses. Differentially polarized γδT-cell subsets exhibit functionally diverse responses to tumors, thus potentially leading to antitumor or protumor responses. Generally, human γδT cells are divided into two major structural subsets according to their TCR δ chain usage: Vδ1 and Vδ2 T cells.
γδT cells display cytotoxicity against hematopoietic and solid tumors in an MHC-independent manner. Although their activation mechanisms differ, both Vδ2 and Vδ1 subsets exert potent antitumor effects. One common γδT-cell-mediated killing pattern involves tumor cell recognition via receptor–ligand interactions. TCR is strongly implicated in controlling Vγ9Vδ2 T-cell cytotoxicity via the recognition of phosphoantigens that are overexpressed in tumor cells and mediate tumor cell lysis. NKG2D binds to MICA/B and ULBPs and induces Vγ9Vδ2 T-cell cytotoxicity against hemopoietic and epithelial tumors. Vγ9Vδ2 T cells are induced to produce IFN-γ and kill hepatocellular carcinoma cells via the interaction of DNAM-1 and nectin-like-5. γδT cells also exhibit strong cytotoxicity against myeloma cells via NKp44. Furthermore, CD56+ γδT cells are capable of killing squamous cell carcinoma of the head and neck, a process that is likely to be mediated by the enhanced expression of granzyme B and upregulated degranulation. Similarly to NK cells, γδT cells induce antibody-dependent cell-mediated cytotoxicity (ADCC) effects, thus resulting in the lysis of tumor cells. According to Tokuyama H et al., CD16+ Vγ9Vδ2 T cells recognize monoclonal antibody-coated lymphoma, chronic lymphocytic leukemia (CLL) and breast cancer cells via CD16 and exert ADCC-dependent cytotoxicity. γδT cells mediate ADCC against B-lineage acute lymphoblastic leukemia via CD19 antibodies. In several other studies, γδT cells have also been shown to mediate ADCC effects against tumor cells via CD16 in the presence of therapeutic antitumor monoclonal antibodies. Moreover, γδT cells have antitumor roles by modulating other effector cells. Although γδT cells demonstrate potent antitumor capacity, paradoxically they also exert protumor effects by promoting noncytotoxic inflammation and regulatory functions that subvert cytotoxic antitumor immunity. Intratumoral γδT cell numbers are positively associated with advanced tumor stages and are inversely correlated with breast cancer prognosis.
