Internal radiation therapy shows promise in pilot study for multiple cancers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

* INCLUSION CRITERIA: 1. Pathologically confirmed malignancy for which high-dose rate brachytherapy is appropriate as a component of their therapeutic regimen. 2. Age greater than 18 years of age. 3. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2. 4. Participant must have a primary medical or surgical oncologist in the community or at National Cancer Institute (NCI) who is willing to collaborate with the Radiation Oncology Branch (ROB) staff in the clinical management of the participant. 5. Participants of childbearing or child- fathering potential must be willing to use a medically acceptable form of birth control, which includes abstinence, while they are being treated on this study. 6. Site-specific inclusion criteria (any one or more of the following): Gynecologic Cancers: Endometrial cancer * Participants at a higher risk of recurrence (because of either grade, myometrial invasion, lymphatic vascular space invasion, tumor size, lymph node status, tumor extension, presence or absence of surgical staging) * Participants who have suffered a recurrence at the vaginal cuff * Participants who are unable to undergo surgery and must have treatment for an inoperable primary endometrial cancer. Cervical cancer * Participants who are unable to undergo surgery and must have treatment for an inoperable primary cervical cancer. * Participants with locally advanced cervical cancer in whom brachytherapy will be integrated as a boost to external beam radiation either in a palliative or curative setting (definitive or post-operative setting). Lung cancer * Participants with an endobronchial component causing symptoms * Participants who cannot undergo resection because of poor lung function or distant lung metastasis Breast cancer * Infiltrating ductal carcinoma or ductal carcinoma in-situ (DCIS), stage T0, T1, and T2 less than or equal to 3.0 cm, N0 and M0, * Participants benefiting from high dose radiation (HDR) as either as a boost or accelerated partial breast irradiation regimen. Prostate Cancer -Participants with localized prostate cancer (T1b-T3b) in whom brachytherapy will be integrated as a boost to external beam radiation or used as monotherapy for definitive management. EXCLUSION CRITERIA: 1. Cognitively impaired participants who cannot give informed consent. 2. Participants currently receiving concurrent investigational chemotherapeutic agents. 3. Participants receiving concomitant chemotherapy administration in the 5 days preceding brachytherapy (except for gynecological cancer patients who may have received concurrent chemotherapy as a component of their treatment regimen) 4. Pregnant or breast-feeding females are excluded because of the potential mutagenic effects on a developing fetus or newborn. 5. Clinically significant unrelated systemic illness (serious infections or significant cardiac, pulmonary, hepatic or other organ dysfunction), which in the judgment of the Principal or Associate Investigator would compromise the participant s ability to tolerate this therapy or are likely to interfere with the study procedures or results. 6. Participants who are in the estimation of the PI, deemed unable or unlikely to adhere to protocol treatment. 7. Abnormal bleeding times or active anti-coagulation therapy. * platelets less than 100,000 per mm(3) * Prothrombin time (PT)/Partial thromboplastin time (PTT) greater than 1.5 the upper normal limit (UNL) 8. Any participant or tumor/anatomical factors that may prevent brachytherapy apparatus from being properly and safely inserted and positioned and from radiation therapy being administered per American Brachytherapy Society (ABS) guidelines. 9. Participants whose malignancy has one or more of the following site-specific criteria disqualifying them from the study: 1\. Breast cancer: * Participants inappropriate for standard breast conservation therapy (Multicentric disease, inability to achieve clear margins); * male participants with breast cancer * autoimmune disorders, including systemic lupus erythematosus (SLE), Scleroderma, etc. * distant metastases; 2\. Prostate cancer: * distant metastases * lymph node metastases
