Journal Requirements:

When submitting your revision, we need you to address these additional requirements.

1. Please ensure that your manuscript meets PLOS ONE's style requirements, including those for file naming. The PLOS ONE style templates can be found at 

https://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf and 

https://journals.plos.org/plosone/s/file?id=ba62/PLOSOne_formatting_sample_title_authors_affiliations.pdf

2. We note that you have indicated that there are restrictions to data sharing for this study. For studies involving human research participant data or other sensitive data, we encourage authors to share de-identified or anonymized data. However, when data cannot be publicly shared for ethical reasons, we allow authors to make their data sets available upon request. For information on unacceptable data access restrictions, please see http://journals.plos.org/plosone/s/data-availability#loc-unacceptable-data-access-restrictions. 

Before we proceed with your manuscript, please address the following prompts:

a) If there are ethical or legal restrictions on sharing a de-identified data set, please explain them in detail (e.g., data contain potentially identifying or sensitive patient information, data are owned by a third-party organization, etc.) and who has imposed them (e.g., a Research Ethics Committee or Institutional Review Board, etc.). Please also provide contact information for a data access committee, ethics committee, or other institutional body to which data requests may be sent.

b) If there are no restrictions, please upload the minimal anonymized data set necessary to replicate your study findings to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers. Please see http://www.bmj.com/content/340/bmj.c181.long for guidelines on how to de-identify and prepare clinical data for publication. For a list of recommended repositories, please see https://journals.plos.org/plosone/s/recommended-repositories. You also have the option of uploading the data as Supporting Information files, but we would recommend depositing data directly to a data repository if possible.

Please update your Data Availability statement in the submission form accordingly.

3. In this instance it seems there may be acceptable restrictions in place that prevent the public sharing of your minimal data. However, in line with our goal of ensuring long-term data availability to all interested researchers, PLOS’ Data Policy states that authors cannot be the sole named individuals responsible for ensuring data access (http://journals.plos.org/plosone/s/data-availability#loc-acceptable-data-sharing-methods).

Data requests to a non-author institutional point of contact, such as a data access or ethics committee, helps guarantee long term stability and availability of data. Providing interested researchers with a durable point of contact ensures data will be accessible even if an author changes email addresses, institutions, or becomes unavailable to answer requests.

Before we proceed with your manuscript, please also provide non-author contact information (phone/email/hyperlink) for a data access committee, ethics committee, or other institutional body to which data requests may be sent. If no institutional body is available to respond to requests for your minimal data, please consider if there any institutional representatives who did not collaborate in the study, and are not listed as authors on the manuscript, who would be able to hold the data and respond to external requests for data access? If so, please provide their contact information (i.e., email address). Please also provide details on how you will ensure persistent or long-term data storage and availability.

4. PLOS requires an ORCID iD for the corresponding author in Editorial Manager on papers submitted after December 6th, 2016. Please ensure that you have an ORCID iD and that it is validated in Editorial Manager. To do this, go to ‘Update my Information’ (in the upper left-hand corner of the main menu), and click on the Fetch/Validate link next to the ORCID field. This will take you to the ORCID site and allow you to create a new iD or authenticate a pre-existing iD in Editorial Manager.

5. Please include captions for your Supporting Information files at the end of your manuscript, and update any in-text citations to match accordingly. Please see our Supporting Information guidelines for more information: http://journals.plos.org/plosone/s/supporting-information.

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: This study focused on skin bacteriostatic agents effect on prevention of radiodermatitis in breast cancer patients. Considering high incidence of radiodermatitis in breast cancer patients after radiotherapy, it could be a useful practical study. However, there are some points which should be addressed:

1- In the objectives of the abstract, define which bacteriostatic agents.

2- In the abstract section, you said this is an observational study, but it is interventional. You provide the bacteriostatic agents to some patients and others receive a medical radiation spray.

3- In the abstract method, the first and second outcomes did not write appropriately.

4- Define the abbreviation at first use (e.g. RTOG).

5- In the introduction section, it is better to discuss more comprehensively the logic of the study. Provide more references. Talk more clearly about bacteriostatic formula (Jiuer).

6- Which patient-reporting system did you use for patients’ assessment?

7- Your exclusion criteria are non-including criteria. Edit the title.

8- As you related the effectiveness of the used formula to its antibacterial effect on staphylococcus, use of concomitant antibiotics with anti-staph efficacy could be a confounding factor.

9- History of autoimmune and connective tissue diseases, skin inflammatory diseases (e.g., ectopic dermatitis), concomitant use of nonsteroidal anti‐inflammatory drugs, and other immunosuppressive or antioxidant medications also could be other confounding factors, effective on radiodermatitis incidence. Did you consider them?

10- The main shortage of the method section is the detailed description of the bacteriostatic formula. You should exactly define its ingredients with dose. Where did it prepare or from which company did you buy it?

11- How did you select patients who receive the medical intervention as you did not have randomization?

12- How did you calculate the sample size?

13- How long did you follow the patients weekly? You said that patients were followed weekly but you just assess them in one time point in result section, which is not clear the time of this assessment.

14- The diagram (figure 1) should be edited. You should define how many patients were included in each arm.

15- The limitations of the study are not defined.

Reviewer #2: Radiodermatitis is a prevalent side effect in breast cancer patients undergoing radiation therapy, manifesting as skin irritation that can range from mild redness to severe ulceration. Effective management is crucial to maintain patient comfort and ensure uninterrupted treatment. This is a big problem for cancer patients and agents that will alleviate or prevent the symptoms are not fully effective, thus there is an unmet need to study the phenomena and bring more human data into the literature to develop effective countermeasures.

This study looks at the use and efficacy of a skin bacteriostatic agent to prevent radiodermatitis in cancer patients. This human clinical trial has interesting results and can be an interest to the readers on the radiotherapy field. However, there are certain aspects of the study were not well described in the manuscript and thus the paper needs major revision before it can be accepted for publication.

1-There is no good description of the bacteriostatic agent that was used anywhere in the paper. Is this a wide spectrum?

2-Also the details in the human study like randomization of the patients etc are not described well either.

3-The text needs editing for typos (ex; page 9, “spay” instead of “spray”)

4-What other aspects of the patient histories were considered to eliminate any key factors that could skewed the results. They all need to be at least discussed if considered and the patients were stratified accordingly. If not, it is still needed to be discussed as a limitation of the study.

5-Power calculations during the study design need to be included.

6- Clinical guidelines for radiodermatitis for Oncology Nursing Society provide evidence-based interventions for managing radiodermatitis in cancer patients. It discusses various topical agents, including those with antibacterial properties, for their role in managing skin reactions during radiotherapy and also emphasize individualized patient care and the importance of clinical judgment in selecting appropriate interventions. MASCC skin toxicity group also have guidelines for suggesting the use of various topical agents, with or without antibacterial properties, and their efficacy in managing radiodermatitis. Did either was followed in the study?

Revision 1

Thank you for giving us the opportunity to submit a revised draft of the manuscript “Do skin bacteriostatic agents reduce acute radiodermatitis in breast cancer patients? A prospective observational study”. We really appreciate the time and effort that you and the reviewers dedicated to providing feedback on our manuscript and are grateful for the insightful comments on and valuable improvements to our paper. We accepted the full comments of the reviewers. Those changes are highlighted within the manuscript. Please see below, for a point-by-point response to the reviewers’ comments and concerns.

Comments from Reviewer 1

1-In the objectives of the abstract, define which bacteriostatic agents.

Answer: Thank you for pointing this out, and we have added this point in the objectives of the abstract.

2-In the abstract section, you said this is an observational study, but it is interventional. You provide the bacteriostatic agents to some patients and others receive a medical radiation spray.

Answer: Thank you for pointing this out and you are very considerate. We have made changes to the study type including the title of the article and the text of the manuscript.

3-In the abstract method, the first and second outcomes did not write appropriately.

Answer: We really appreciate your valuable advice. We have made changes to the manuscript. The first outcome was evaluated using the Radiation Therapy Oncology Group (RTOG) criteria. The second outcome was the patient's reported symptoms of radiodermatitis, which included itching, pain, tightness, burning and swelling.

4-Define the abbreviation at first use (e.g. RTOG).

Answer: We really appreciate your valuable advice. We have made changes in the manuscript.

5- In the introduction section, it is better to discuss more comprehensively the logic of the study. Provide more references. Talk more clearly about bacteriostatic formula (Jiuer).

Answer: We really appreciate your valuable advice. We followed clinical practice guidelines recommending the use of antimicrobial dressings during radiotherapy. In this study, we used the Jiuer antibacterial agent, which is produced by Shandong Jiuer Pharmaceutical Biotechnology Co. Ltd. This agent has an inhibitory effect on Staphylococcus aureus on the skin's surface and fully complies with national requirements. The relevant information about this drug is described in the Methods section.

6-Which patient-reporting system did you use for patients’ assessment?

Answer: Thank you for pointing this out and you are very considerate. A review of the relevant literature revealed that there is no uniform scale for patients to self-report symptoms associated with radiation dermatitis. Therefore, this study used a uniform radiodermatitis record card to observe and record additional symptoms.

7- Your exclusion criteria are non-including criteria. Edit the title.

Answer: We really appreciate your valuable advice. We have amended the inclusion and exclusion criteria in the manuscript.

8- As you related the effectiveness of the used formula to its antibacterial effect on staphylococcus, use of concomitant antibiotics with anti-staph efficacy could be a confounding factor.

Answer: Thank you very much for your valuable advice, your consideration is right. The inclusion criteria for the manuscript have been amended to include patients who were not prescribed antibiotics.

9-History of autoimmune and connective tissue diseases, skin inflammatory diseases (e.g., ectopic dermatitis), concomitant use of nonsteroidal anti‐inflammatory drugs, and other immunosuppressive or antioxidant medications also could be other confounding factors, effective on radiodermatitis incidence. Did you consider them?

Answer: We really appreciate your valuable advice. We have made changes in the inclusion criteria.

10-The main shortage of the method section is the detailed description of the bacteriostatic formula. You should exactly define its ingredients with dose. Where did it prepare or from which company did you buy it?

Answer: Thank you very much for your valuable advice, your consideration is right. We have added details of the skin bacteriostatic agents to the 'Methods' section of the manuscript.

11-How did you select patients who receive the medical intervention as you did not have randomization?

Answer: Thank you for pointing this out and you are very considerate. The application of skin antibacterial agents was based on the skin condition and radiation dose of the patients, as determined by the radiotherapy doctors. Consent was obtained from the patients. Therefore, this study was a non-randomised controlled trial.

12-How did you calculate the sample size?

Answer: We apologize for not mentioning the sample size in our manuscript. According to a literature review, the incidence of grade 2 or higher radiodermatitis is 45%. Using G Power software with α=0.05 (bilateral) and testing the efficacy at the level of 1-β=0.90, the expected incidence of radiodermatitis with skin bacteriostatic agents is 20%. According to the formula for calculating sample size, 41 cases are needed for each of the experimental and control groups. In the real trial, however, 47 cases were collected in the experimental group and 136 in the control group.

13-How long did you follow the patients weekly? You said that patients were followed weekly but you just assess them in one time point in result section, which is not clear the time of this assessment.

Answer: Sorry, we should have made it clearer. This study involves weekly assessments of skin conditions in the radiation fields of patients until two weeks after the end of radiotherapy. The study analyses the most severe cases of radiation dermatitis occurring during radiotherapy and up to two weeks afterwards, as these affect patients more severely.

14-The diagram (figure 1) should be edited. You should define how many patients were included in each arm.

Answer: We really appreciate your valuable advice. We have made changes in figure 1.

15-The limitations of the study are not defined.

Answer: Thank you for pointing this out and you are very considerate. We have added limitations to the manuscript.

Comments from Reviewer 2

1-There is no good description of the bacteriostatic agent that was used anywhere in the paper. Is this a wide spectrum?

Answer: Yes, at present, moderate to severe radiation dermatitis mainly occurs with the intravenous administration of antibiotics to control infection. Topical application of antimicrobial agents to the skin in the radiation field is less common, so our study investigates the topical application of bacteriostatic agents for the treatment of radiation dermatitis, providing a reference point for its prevention.

2-Also the details in the human study like randomization of the patients etc are not described well either.

Answer: Thank you for pointing this out and you are very considerate. This study is a real-world, non-randomised controlled trial, and it has been added to the manuscript.

3-The text needs editing for typos (ex; page 9, “spay” instead of “spray”)

Answer: Thank you for pointing this out, and we have corrected it in the manuscript.

4-What other aspects of the patient histories were considered to eliminate any key factors that could skewed the results. They all need to be at least discussed if considered and the patients were stratified accordingly. If not, it is still needed to be discussed as a limitation of the study.

Answer: We really appreciate your valuable advice. We have made changes in the inclusion criteria.

5-Power calculations during the study design need to be included.

Answer: Thank you very much for suggesting changes to the sample size for this study. We have updated the 'Statistical Analysis' section of the manuscript accordingly.

5-Clinical guidelines for radiodermatitis for Oncology Nursing Society provide evidence-based interventions for managing radiodermatitis in cancer patients. It discusses various topical agents, including those with antibacterial properties, for their role in managing skin reactions during radiotherapy and also emphasize individualized patient care and the importance of clinical judgment in selecting appropriate interventions. MASCC skin toxicity group also have guidelines for suggesting the use of various topical agents, with or without antibacterial properties, and their efficacy in managing radiodermatitis. Did either was followed in the study?

Answer: Yes, we follow clinical guidelines and the MASCC skin toxicity group in our clinical practice. Patients are treated with a radiation spray to protect their skin during radiotherapy, and those with more severe symptoms are given a corticosteroid ointment. In order to minimize confounding factors, patients using corticosteroid ointment were excluded from this study.
