Patients randomized to the SOC treatment planning arm will receive a treatment planning computed tomography (CT) scan followed by dosimetric planning with a medical dosimetrist; and the plan will be reviewed by a medical physicist and radiation oncologist. This is the current standard practice for all radiation oncology patients.

Patients randomized to the MLAP arm will receive a treatment planning scan followed by MLAP through the RapidPlan module produced by Varian. Of note, RapidPlan is an FDA cleared module with treatment planning being the approved usage for the program. The RapidPlan module has site specific treatment packages for different disease sites. These separate disease specific packages have different capabilities. For example, the Head and Neck package currently audits dosimetrist-generated plans for possible improvements. The MLAP arm of the trial will leverage the RapidPlan module's full capabilities upwards to the FDA-approved usage.

Radiation therapy simulation, target delineation, dosing, localization, and follow-up will be followed per standard of care practices and/or at the discretion of the treating radiation oncologist. To elaborate, patients will receive a treatment planning CT (computed tomography) scan, followed by normal tissue delineation through the physician and/or medical dosimetry assistant, followed by target delineation by the physician, followed by radiation treatment planning with the dosimetrist and medical physicist. The preliminary plan will be run through the RapidPlan module, which will give a list of possible improvements to the plan. The dosimetrist will then make an amendment to the plan according to RapidPlan suggestions, followed by plan change requests and approval by the physician.

Will be assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck module (EORTC QLQ-H&N35). The EORTC QLQ-H&N35 is a 35-item questionnaire used to assess symptoms encountered specifically by patients with head and neck cancer. The H&N35 consists of 7 multiple-item scales (Pain, Swallowing, Senses, Speech, Social eating, Social contact, and Sexuality), in addition to 11 single items (e.g., Opening mouth, Sticky saliva, Dry mouth, etc.). Scores are combined into an overall score ranging from 0=Best to 100=Worst. Swallowing score will be measured at baseline (up to 30 days prior to treatment planning), at the end of Radiation Treatment (+ 14 days), and 3 months post Radiation Treatment (+/-30 days from 3 months post-radiotherapy).

Assessed according to Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Toxicities will be recorded at baseline (up to 30 days prior to treatment planning), at the end of Radiation Treatment (+14 days), and 3 months post Radiation Treatment (+/-30 days from 3 months post-radiotherapy).

Quality of life scores will be compared between arms, as measured by the 6 remaining subscales and 11 single item scores of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck module (EORTC QLQ-H&N35). EORTC scores will be recorded at baseline (up to 30 days prior to treatment planning), at the end of Radiation Treatment (+14 days), and 3 months post Radiation Treatment (+/-30 days from 3 months post-radiotherapy).
