CIPN afflicts between 30% and 40% of patients undergoing chemotherapy. Antineoplastic agents in chemotherapy are designed to eliminate rapidly dividing cancer cells, but they can also damage healthy structures, including the peripheral nervous system. [1] CIPN involves various symptoms such as tingling, pain, and numbness in the hands and feet. [2]
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Cutting through or removal of nerves is used in people with cancer pain who have short life expectancy and who are unsuitable for drug therapy due to ineffectiveness or intolerance. Because nerves often carry both sensory and motor fibers, motor impairment is a possible side effect of neurectomy.
Lymphangiosarcoma is a rare cancer which occurs in long-standing cases of primary or secondary lymphedema (swelling due to lymphatic system obstruction). It involves either the upper or lower lymphedematous extremities but is most common in upper extremities. [1]
Similar brief shocks can be experienced when any other nerve is tweaked (e.g. a pinched neck nerve may cause a brief shock-like paresthesia toward the scalp). In the older age group, spinal column irregularities may tweak the spinal cord briefly when the head or back is turned, flexed, or extended into brief uncommon positions (Lhermitte's sign).
Treatments that rendered him cancer-free, including chemotherapy, a bone marrow transplant, and radiation, left him with permanent lung and respiratory problems and he died in 2001 just after turning 16. [92] [93] [circular reference] Victoria Duval, American tennis player, was diagnosed in 2014. [94]
If diagnosed early, initiation of early treatment to prevent loss of nerve axons is recommended. However, many individuals are left with residual numbness, weakness, tremors, fatigue and other symptoms which can lead to long-term morbidity and diminished quality of life. [2]
Globally, head and neck cancer accounts for 650,000 new cases of cancer and 330,000 deaths annually on average. In 2018, it was the seventh most common cancer worldwide, with 890,000 new cases documented and 450,000 people dying from the disease. [12] The risk of developing head and neck cancer increases with age, especially after 50 years.
