Hypofractionated Radiation Therapy for Merkel Cell Carcinoma

Conditions

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This phase II trial tests whether hypofractionated radiation works to treat patients with Merkel cell carcinoma. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a fewer number of days than tradition radiation therapy courses for Merkel cell carcinoma. This may be less suppressive of the immune response to tumors and should be helpful for patient convenience.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years

Sexes Eligible for Study:ALL

Accepts Healthy Volunteers:No

Standard Ages:ADULT, OLDER_ADULT

Inclusion Criteria	Exclusion Criteria
* Patients must have histologically or cytologically confirmed MCC. * Patients must have no evidence of distant metastasis as determined by clinical examination and any form of imaging. * If planned for adjuvant primary tumor radiation therapy a patient should have had surgical excision of a primary MCC tumor within 4 months of starting RT. * If planned for adjuvant nodal radiation therapy a patient should have had: * Prior positive sentinel lymph node biopsy with any degree of nodal involvement within 4 months of starting RT and no completion nodal dissection, or * Lymph node dissection within 4 months of starting RT and high risk nodal disease (receipt of neoadjuvant immunotherapy, ECE, \>1 involved node, \>1 cm nodal disease). * Immunotherapy is permitted at any time and may specifically be administered prior to RT, concurrent with RT or after RT. * Age ≥18 years because MCC is extremely rare in patients \<18 years of age and RT is considered high risk in this population due to risk of secondary malignancy and potentially growing tissues that may be adversely impacted by RT. * ECOG performance status ≤3. * Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial. * RT is a known teratogen. For this reason women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (refer to MDA Policy CLN 1114) This includes all female patients, between the onset of menses and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following: • Postmenopausal (no menses in greater than or equal to 12 consecutive months). • History of hysterectomy or bilateral salpingo-oophorectomy. • Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy). • History of bilateral tubal ligation or another surgical sterilization procedure. Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. * Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 6 months after completion of RT. * Ability to understand and the willingness to sign a written informed consent document.	* Previous radiation therapy to the site of planned primary or nodal radiation treatment such that the prior site of treatment would be encompassed by the radiation field needed to treat the current cancer. In other words, treatment on this trial would require re-irradiation of tissues. * Patients with distant metastases * Pregnant women are excluded from this study because RT is a known teratogen. * Patients who are less than 18 years of age becase RT is extremely rare in this population and the treatment agent is a known carcinogen.
