Swallowing Outcomes and Circulating Tumor DNA in Patients With HPV Related Oropharyngeal Cancer Treated With Transoral Surgery and Reduced Intensity Adjuvant Therapy

Korábbi kezelés

• Patients may not have received previous therapy for their head and neck squamous cell carcinoma (SCC), including chemotherapy, radiation therapy, or surgery beyond biopsy
• Serious concomitant systemic disorders (including active infections) that would compromise the safety of the patient or compromise the patient's ability to complete the study, at the discretion of the investigator
• Women who are pregnant, due to the teratogenic effects of radiation therapy and chemotherapy on the unborn fetus. Women of childbearing age must agree to undergo a pregnancy test prior to therapy and to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for 6 months after. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

Más betegség

  • Patient had a second primary malignancy but has been treated and disease free for at least 3 years
  • In situ carcinoma (e.g. in situ carcinoma of the cervix)
  • Non-melanomatous carcinoma of the skin
• Patients with metastatic disease beyond the neck will be excluded

Laborértékek
