Oral Health in Cancer Patients

June 19, 2021 by No Comments

For many survivors of cancer there aren’t any specific expected late complications or oral health considerations. But, survivors of cancer who are prescribed bone-modifying agents, neck and head cancer survivors, survivors of childhood cancer, and those treated on protocols including stem cell transplantation and high-dose chemotherapy make up high-risk groups for complications of oral health. These individuals might require long-range dental follow-up after cancer therapy completion.

Bone-modifying Agents

Individuals who have been treated within the past or who are presently being treated with bone-modifying agents (that is, denosumab or bisphosphonates) are at greater risk of developing osteonecrosis of the jaw that may be related to long-range discomfort. The ones at risk involve survivors of more typical cancers, like breast and prostate cancer.

Neck and Head cancer

Dental and oral complications are typical in neck and head cancer survivors due to the treatment field oftentimes including, by their proximity, those organs needed for communicating, eating, and breathing. As a consequence, numerous complications may arise, which directly impact the oral cavity and surrounding organs (that is, the thyroid gland) and structures. They involve trismus, osteordionecrosis, salivary gland hypofunction, and facial disfigurement. Additionally, those individuals are at risk for second primary and recurrence lesion alike.

Childhood cancer

Even though cancer includes the 2nd leading death cause in kids, survivors of childhood cancer comprise a small part of cancer survivors. For example, within the U.S., there are around 300,000 childhood cancer survivors. For these individuals radiation therapy and chemotherapy to the neck and head region may possess an adverse impact upon normal development and growth of teeth and the surrounding structures.

Irregular discoveries involve tinier than normal Prostate Protocol teeth and failure of an individual’s teeth to develop. Within one report that involved 150 kids, the prevalence of these conditions was 19% and 9% (as compared with 0% and 4% amongst 193 age-fit controls).

Treatment-associated risk factors of oral complications were witnessed in one report from a Childhood Cancer Survivor Study. Within the study, 8522 survivors of cancer and 2831 of the survivor’s siblings responded to a questionnaire and interviews on oral health. The average age at cancer diagnosis was 6 years and the average time from diagnosis to interview was twenty-two years. Most cancer survivors indicated previous treatment using radiation therapy (64%) and/or chemotherapy (76%). Risk factors related to at the minimum of one dental issue involved this: generally, treatment within a younger age is related to a higher probability for long-range effects. As there are complications that affect development and growth, patients might need the experience of maxillofacial and oral surgeons, prosthodontists, and orthodontists for comprehensive management.

GVHD (Chronic graft-versus-host disease)

Individuals treated with HCT (high-dose chemotherapy) followed up by allogeneic HCT-SCT (hematopoietic stem cell transplantation) will be at a higher risk for oral complications if they develop GVHD (chronic graft-versus-host disease), especially for dental caries development. Oral complications will affect over 80% of individuals who have GVHD. Even though individuals who undergo an autologous SCT will be at risk of acute complications (that is, infection and mucositis) instantly after transplantation, after immune reconstitution, there will include no certain related late oral complications.

Individuals who have GVHD oftentimes need prolonged immunosuppressive therapy, placing them at long-run risk of oral infections. They’re also at a higher risk for oral cavity squamous cell carcinoma, likely because of a mixture of chronic inflammation related to GVHD, and long-range immunosuppression.
