Keywords
Radiation Therapy, Reflectance Confocal Microscopy (RCM)/Optical Coherence Tomography (OCT), 20-553
Brief summary
The purpose of this study is to find out if radiation therapy (RT) guided by the new reflectance confocal microscopy (RCM)/optical coherence tomography (OCT) device is an effective treatment for basal cell carcinoma (BCC). The researchers will also look at the side effects from RT guided by the RCM/OCT device. In addition, will determine the quality of life before and after treatment by having the participant fill out questionnaires.
Interventions
Patients will undergo RCM/OCT with an imaging specialist in the Dermatology Service. This is not expected to take longer than 30 minutes. Prior to imaging, a digital photograph will be taken of the biopsy proven BCC.
After the completion of skin imaging, patients will undergo simulation and tumor radiotherapy. An equivalent total dose in 2 Gy fractions (EQD2) of 45-46 Gy will be delivered for treatment.

Eligibility
Inclusion criteria
* Biopsy proven basal cell carcinoma °Up to 3 tumors per patient can be treated per protocol synchronously or metachronously * Clinical stage T1 or T2 by Union International to Control Cancer 8th edition system * ≤40 mm in maximum dimension * no deep invasion (beyond subcutaneous fat or \>6 mm from granular later of dermis to deepest point of carcinoma) * no perineural invasion of nerves ≥0.1 mm diameter or deeper than dermis * no intraneural invasion * no bone erosion, invasion or foraminal transgression NOTE: For the purposes of protocol inclusion, if any of the features mentioned above is not included in the pathology report they will considered absent. * ≥18 years old * Amenable to RCM/OCT and radiation therapy in opinion of investigator * Some anatomic locations may preclude imaging by RCM/OCT may not be amenable to RCM/OCT imaging * Some medical comorbidities may preclude the delivery of radiation therapy (conditions rendering patients hypersensitive to ionizing radiation, or unable to undergo treatment) * Able and willing to complete the Skindex 16 and Skin Cancer Index (must be able to understand English or Spanish)
Exclusion criteria
* Medical contraindication to radiation therapy in the opinion of the investigator * Prior cancer radiotherapy which precludes the ability to safely deliver radiation therapy in the opinion of the investigator * High likelihood of protocol non-compliance in the opinion of the investigator °Patients who demonstrate unwillingness to undergo protocol-defined treatment or follow-up procedures will be ineligible to participate
