Progressive, Irreversible Hearing Loss Can Result From Radiation Therapy And Platinum-based Chemotherapy Drugs Such As

Ototoxicity monitoring before, during, and after treatment is an important component in the early detection and management of hearing loss in young cancer patients. A case study approach using fictional audiological test results representative of actual cases seen in our clinic will be used to describe various types of hearing loss caused by platinum-based chemotherapeutic agents and cranial radiation therapy. The platinum-based compounds carboplatin and cisplatin are effective chemotherapy agents commonly used to treat a variety of childhood cancers. OHSU study shows platinum-based ototoxicity in children prevalent, but new drugs offer prevention hope. Johnson, now 33, has suffered since 1986 from the effects of ototoxicity, a condition in which platinum-based chemotherapy drugs, such as carboplatin and the more common cisplatin, damage the tiny hair cells in the inner ear that vibrate in response to sound waves. This leads to progressive, irreversible hearing loss and reduced quality of life for patients. Despite surgery and intense radiation therapy to remove the brain tumor, Johnson says the hearing loss resulting from the chemotherapy for the shoulder tumor has been the most disabling. Progressive, irreversible hearing loss can result from radiation therapy and platinum-based chemotherapy drugs such as carboplatin and cisplatin.

Patients who undergo radiation therapy for head and neck cancer appear more likely to. Progressive, irreversible hearing loss can result from radiation therapy and platinum-based chemotherapy drugs such as carboplatin and cisplatin. Cancer treatments can impact hearing, with chemo and radiation drugs often resulting in. Progressive, irreversible hearing loss can result from radiation therapy and platinum-based chemotherapy drugs such as carboplatin and cisplatin. Some chemotherapy drugs, other medications or radiation used to treat children’s cancer can damage hearing. Conductive hearing loss may improve over time, but sensorineural hearing loss is usually permanent.

Chemotherapy can be limited by these side effects. Anticancer Drugs. Among functional impairments that result from cancer treatment, hearing loss. Platinum agents (cisplatin and carboplatin) have improved cure rates of. cisplatin-based regimens reportedly develop some degree of permanent hearing loss. with cisplatin, radiation therapy can substantially exacerbate the hearing loss.

Chemotherapy can be limited by these side effects. Anticancer Drugs. Among functional impairments that result from cancer treatment, hearing loss. Platinum agents (cisplatin and carboplatin) have improved cure rates of. cisplatin-based regimens reportedly develop some degree of permanent hearing loss. with cisplatin, radiation therapy can substantially exacerbate the hearing loss.

Hearing loss from cisplatin or carboplatin is permanent and may have a delayed onset, with progressive loss occurring many years after completion of therapy. The validity and reliability of the SIOP grading scale still need to be established, but the objective of the working group was to produce a measure that is practical and can be implemented widely in clinical research settings so that results across studies can be fairly compared. Of continuing concern, cranial radiation therapy and platinum-based chemotherapy are commonly used together to treat a variety of childhood brain tumors and head and neck cancers. In addition, because cranial radiation can potentially damage any of the auditory structures from the external ear canal up to the primary auditory pathways, the nature and pattern of hearing loss can be atypical and unpredictable, making the use of an ototoxicity grading scale designed for platinum-agents, such as the SIOP scale23 and the others shown in Table 1, challenging and potentially inaccurate for children treated with radiation exposure to the head. The effect of hearing loss in young children is significant and can influence speech and language development, educational achievement, and social-emotional development. When carboplatin is administered in alternate cycles with cisplatin, or after cisplatin chemotherapy, significant hearing loss can result. Clinical trials list ototoxicity as an adverse event based on a numeric grading system, the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) , version 3. Patients assigned to platinum therapy were referred to the Pediatric Audiology Program at Oregon Health and Science University Doernbecher Children’s Hospital. Hearing. Chemotherapy Toxicity. Platinum agents, cisplatin and carboplatin, may result in irreversible high-frequency sensorineural hearing loss5. Loss of high frequency sounds can be detrimental to children’s cognitive and social development. Other Drugs: However, many of them interfere with the therapeutic effect of cisplatin, and. prevention strategies. cisplatin ototoxicity hearing loss protective treatment. to symmetrical 76, progressive, irreversible, cumulative and dose-dependent. in patients with ovarian carcinoma receiving platinum-based chemotherapy Gynecol. The propensity of specific classes of drugs to cause ototoxicity has been well established, and over 100 classes of drugs have been associated with ototoxicity. The list includes aminoglycosides and other antibiotics, platinum-based antineoplastic agents, salicylates, quinine, and loop diuretics. Hearing loss can be temporary but is usually irreversible with most agents. No therapy is currently available to reverse ototoxic damage; Chemotherapy can be given with radiotherapy to enhance the therapeutic effect. Both methotrexate and cisplatin can cause severe damage to the renal tubules.

Through multimodal therapy, including chemotherapy, radiotherapy, surgery, and peripheral blood stem cell transplantation, the survival rate in patients with NBL have improved while treatment-related complications have also increased. Treatment-related ototoxicity, mainly from cisplatin, can result in profound hearing loss requiring cochlear implantation (CI). Treatment is based on the risk stratification using age, stage, MYCN oncogene status and pathologic classification [2]. Platinum-related sensorineural hearing loss is generally irreversible, and occurs bilaterally in 22%-70% of children [2, 3]. His research interests are also in hearing loss, and include neonatal hearing screening, genetics of hearing loss, otoacoustic emissions, auditory physiology, and ototoxicity. His current research interests include the radiologic evaluation of congenital inner ear anomalies, and the analysis of how Connexin-based mutations can alter management of infants with congenital hearing loss. The platinum chemotherapy agents cisplatin and carboplatin are widely used in the treatment of adult and pediatric cancers. Hearing loss can be categorised as mild, moderate, severe, or profound. Extremely loud sounds may cause instant and permanent hearing loss. [35] The most important group is the aminoglycosides (main member gentamicin) and platinum based chemotherapeutics such as cisplatin and carboplatin. Apparently it’s the carbo part that can cause problems has anyone experienced this? Thanks for your help. How does cancer treatment cause hearing loss? Regardless of age, cancer patients may experience a variety of common side effects caused by chemo and radiation therapies, such as nausea and hair loss. Com/2012/10/22/the-truth-about-chemotherapy-and-hear ing-loss/ Johnson, now 33, has suffered since 1986 from the effects of ototoxicity, a condition in which platinum-based chemotherapy drugs, such as carboplatin and the more common cisplatin, damage the tiny hair cells in the inner ear that vibrate in response to sound waves. This leads to progressive, irreversible hearing loss and reduced quality of life for patients. Stereotactic Body Radiotherapy vs Radiofrequency Ablation in Inoperable. use of blood-thinning drugs such as heparin does not increase rates of major bleeding. Patients With Breast Cancer Likely to Respond to Platinum-Based Therapy. the therapy has a known side effect of permanent hearing loss, resulting from. Although surgery and radiation therapy are usually ad-. Radiotherapy is not recommended in young children because of its severe adverse effects on cognitive and neuroendocrine function. This report suggests a new approach using combined intraarterial and IV carboplatin-based chemotherapy for patients for whom first line treatment has already failed. When the platelet nadir was
