Dear Dr. Yoram,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

The aim of the manuscript and its usefulness should be clearly defined. Additionally, the manuscript presents several methodological problems, pointed out by the reviewers, that must be carefully resolved before it can be considered for publication.

Please submit your revised manuscript by Dec 15 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org.

For additional information about PLOS ONE ethical requirements for human subjects research, please refer to http://journals.plos.org/plosone/s/submission-guidelines#loc-human-subjects-research.

3. In your Data Availability statement, you have not specified where the minimal data set underlying the results described in your manuscript can be found. PLOS defines a study's minimal data set as the underlying data used to reach the conclusions drawn in the manuscript and any additional data required to replicate the reported study findings in their entirety. All PLOS journals require that the minimal data set be made fully available. For more information about our data policy, please see http://journals.plos.org/plosone/s/data-availability.

Upon re-submitting your revised manuscript, please upload your study’s minimal underlying data set as either Supporting Information files or to a stable, public repository and include the relevant URLs, DOIs, or accession numbers within your revised cover letter. For a list of acceptable repositories, please see http://journals.plos.org/plosone/s/data-availability#loc-recommended-repositories. Any potentially identifying patient information must be fully anonymized.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Dear Authors,

Congratulations with submission of the article Radiation therapists’ perceptions of thermoplastic mask use for HNC - A

qualitative study. The article describes an important issue regarding the perception of radiation therapists and the use of thermoplastic masks. Some minor changes:

1. line 104: "patients" should be replaced by "RTT" or " participants"

2. Could you suggest more practical things that could be improved e.g. giving education, 5 times a year? creating protocols? What would be the next step?

3. For future: It would be interesting to see a follow-up of the situations, have things improved? what interventions work and what do not?

Overall, an important and interesting topic.

Reviewer #2: The objective should have been better defined.

Academic training and the number of years of professional experience should be included.

It does not mention who carried out the interviews and content analysis.

The conclusions are in part aligned with the objective.

The study is limited to a single location, which makes this a case study, with all the limitations that this type of study entails.

Reviewer #3: The article „Radiation therapists’ perceptions of thermoplastic mask use for head and neck cancer patients undergoing radiotherapy at Ocean Road Cancer Institute in Tanzania: A qualitative study” is interesting especially due to its setting in a low-resource setting. However, I think the novelty of the study should be emphasized, especially since the use of thermoplastic masks in ENT cancers has become standard. Additionally, I have several questions/comments, listed below.

1. Who designed the questionnaire? How were the questions chosen?

2. The authors refer to RTTs as radiation specilists. Does this mean they are all physicians? Or were there also nurses and physicists involved in the study?

3. Also in the Material and Method section, I think more details should be offered. How were the data analyzed? What are the six steps used for analysis? Because to me it seems that only a summary of the interviews is provided

4. The authors refer to the concept of recycling the thermoplastic masks. I think more details should be offered on the subject, especially since this is not standard

5. In the Discussions section, the authors state that „This study revealed significant differences in participants’ understanding of the thermoplastic mask preparation process.” Where was this detailed in the Results section?

Minor comments

Please revise: „This is a perforated plastic sheet that is soaked in warm water which then becomes soft and flexible, moulded on the patient’s face, cools after a certain time and becomes hard and finally keeps a final shape of the patient’s anatomy (6,7)”, „During thermoplastic mask preparation, RTT explains in detail the procedure to the patient, position the patient, and perform quick and accurate construction of thermoplastic mask by adhering to the manufacturer’s guidelines while working as a team and maintaining proper documentation (9).”, „This is because of avoiding its loss, easy identification during treatment, shape maintenance and prevention of infection transmission.”

Reviewer #4: Study seems to address the key routine issues and conducted well. However,I have few queries as below

* Experience and Knowledge level of the RTTs involved( Aged 27-49 years) is missing

* internal consistency reliability test and coherence of the Thematic analysis is missing

Kindly address these queries

The Discussion could be more accomplished, expression as "This study revealed significant differences in participants’ understanding of the thermoplastic mask preparation process" (l248), are "too strong".
