cdr2 antigen-specific CD8+ T cells were subsequently described in more anti-Yo-positive PCD patients,. These T cells are likely components in both the anti-tumor immune response and in the neuronal degeneration. Diagnosis
Of particular note, PCD symptoms precede the diagnosis of the underlying cancer in the majority of cases, and often present insidiously and progress rapidly for weeks to months to a severely disabled state followed by a variable plateau period that can last for months to years. Therefore, newly developing cerebellar ataxia should always prompt proper diagnostic measures to exclude PCD. Treatment
Tumor removal is still the therapeutic mainstay with very early treatment being essential to prevent irreversible neuronal loss. Immunosuppressive or immunomodulatory treatments are often ineffective. There may be a role for high-dose gammaglobulin therapy in the treatment PCD, but due to the rare occurrence of this disease, controlled trials of this therapy may be difficult. References

Various emollients (creams) are recommended to keep skin moist. Corticosteroids and pyridoxine have also been used to relieve symptoms. Other studies do not support the conclusion. A number of additional remedies are listed in recent medical literature. Among them henna and 10% uridine ointment which went through clinical trial. Prognosis
Hand-foot invariably recurs with the resumption of chemotherapy. Long-term chemotherapy may also result in reversible palmoplantar keratoderma. Symptoms resolve 1–2 weeks after cessation of chemotherapy (Apisarnthanarax and Duvic 2003). The range is 1-5 wks, so it has recovered by the time the next cycle is due. Healing occurs without scarring unless there has been skin ulceration or necrosis (skin loss/death). With each subsequent cycle of chemotherapy, the reaction will appear more quickly, be more severe and will take longer to heal. History
Hand-foot syndrome was first reported in association with chemotherapy by Zuehlke in 1974. Synonyms for acral erythema (AE) include: hand-foot syndrome, palmar-plantar erythrodysesthesia, peculiar AE, chemotherapy-induced AE,  toxic erythema of the palms and soles, palmar-plantar erythema, and Burgdorfs reaction. Common abbreviations are HFS and PPE. References
