- Change in PGE2 concentration levels in normal colorectal mucosa [ Time Frame: Baseline to 6 months ]Response will be defined as >= 30% reduction in PGE2 levels. Pairwise comparisons by the two-sample t-test among the three groups (low-dose versus control, high-dose versus control, and high-dose versus low-dose) will be used. The calculation adjusts for 3 multiple comparisons using the Bonferroni correction to achieve a two-sided 5% type I error. The point estimate and the 95% exact confidence interval for the response rate will be calculated in each arm.
- Minimal biologically effective dose of naproxen that induces a modulation of PGE2 levels [ Time Frame: Up to 6 months ]
- Incidence of toxicity [ Time Frame: Up to 6 months ]Will be graded according to National Cancer Institute Common Criteria for Adverse Events version 4.0. Descriptive statistics will be used to monitor the type and grade of toxicities. The frequency of toxicities will be compared between the placebo and naproxen groups.
- Naproxen concentrations in plasma samples [ Time Frame: 6 months ]A t-test or the Wilcoxon rank sum test will be applied for the pairwise comparison of the changes of continuous markers among groups.
- Naproxen concentrations in normal colorectal mucosa [ Time Frame: 6 months ]A t-test or the Wilcoxon rank sum test will be applied for the pairwise comparison of the changes of continuous markers among groups.
- PGE-M levels in urine samples [ Time Frame: 6 months ]A t-test or the Wilcoxon rank sum test will be applied for the pairwise comparison of the changes of continuous markers among groups.
- Change in number of polyps observed in the rectosigmoid area [ Time Frame: Baseline to 6 months ]A t-test or the Wilcoxon rank sum test will be applied for the pairwise comparison of the changes of continuous markers among groups.
- Changes in the microRNA profile of the normal colorectal mucosa [ Time Frame: Baseline to 6 months ]Bioinformatic methods such as the beta-uniform mixture (BUM) model to account for multiple testing by controlling the false discovery rate (FDR), the Wilcoxon rank-sum test with empirical Bayes, and the significance analysis of microarrays (SAM) with the control of the FDR will be applied using the Object-Oriented Microarray and Proteomic Analysis (OOMPA) program.
- Changes in gene expression mRNA profiles of the normal colorectal mucosa [ Time Frame: Baseline to 6 months ]Bioinformatic methods such as the BUM model to account for multiple testing by controlling the FDR, the Wilcoxon rank-sum test with empirical Bayes, and the SAM with the control of the FDR will be applied using the OOMPA program.
- Changes in the mutational rate of the normal colorectal mucosa [ Time Frame: Baseline to 6 months ]Bioinformatic methods such as the BUM model to account for multiple testing by controlling the FDR, the Wilcoxon rank-sum test with empirical Bayes, and the SAM with the control of the FDR will be applied using the OOMPA program.
- Changes in the microbiome of the normal colorectal mucosa [ Time Frame: Baseline to 6 months ]Bioinformatic methods such as the BUM model to account for multiple testing by controlling the FDR, the Wilcoxon rank-sum test with empirical Bayes, and the SAM with the control of the FDR will be applied using the OOMPA program.
- Changes in the PGF2, PGD2, Thromboxane B2, 9a11b-PGF2a and 6-KetoPGF1a levels of the colorectal tissue [ Time Frame: Baseline to 6 months ]Bioinformatic methods such as the BUM model to account for multiple testing by controlling the FDR, the Wilcoxon rank-sum test with empirical Bayes, and the SAM with the control of the FDR will be applied using the OOMPA program.
- Changes in the stem cell and epithelial differentiation marker levels [ Time Frame: Baseline to 6 months ]Bioinformatic methods such as the BUM model to account for multiple testing by controlling the FDR, the Wilcoxon rank-sum test with empirical Bayes, and the SAM with the control of the FDR will be applied using the OOMPA program.
- Changes in the number and type of immune and mesenchymal cells recruited to the colorectal mucosa [ Time Frame: Baseline to 6 months ]Will be assessed by using a multiplex platform based on imaging cell cytometry (IMC) in a tissue microarray (TMA).

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
Participants must have Lynch syndrome defined as meeting any of the following:
- "Mutation-positive Lynch syndrome": carriers or obligate carriers (by pedigree) of a pathogenic mutation in one of the DNA mismatch repair (MMR) genes (i.e. mutL homolog 1 [MLH1], mutS homolog 2 [MSH2]/epithelial cell adhesion molecule [EPCAM], mutS homolog 6 [MSH6], or PMS2 postmeiotic segregation increased 2 [S. cerevisiae] [PMS2]) or
- "Mutation-negative Lynch syndrome": patients with a personal history of a non-sporadic MMR deficient premalignant lesion (i.e. polyp) or a non-sporadic MMR deficient malignant tumor (where "non-sporadic MMR deficient" is defined by: microsatellite-instability high by either immunohistochemistry or microsatellite instability [MSI] testing or both, but no evidence of MLH1 promoter methylation in cases with loss of both MLH1 and PMS2, and/or no evidence of v-raf murine sarcoma viral oncogene homolog B [BRAF] mutation in cases with loss of both MLH1 and PMS2) but germline MMR genetic testing showed either a variant of unknown significance or mutation negative result or had declined germline MMR genetic testing
- Participants must not have evidence of active/recurrent malignant disease for 6 months
- Participants must be at least 6 months from any prior cancer-directed treatment (such as surgical resection, chemotherapy, immunotherapy, hormonal therapy or radiation)
- Participants must have endoscopically accessible distal colon and/or rectal mucosa (i.e. participants must have at least part of the descending/sigmoid colon and/or rectum intact)
- Participants must consent to one standard of care lower gastrointestinal (GI) endoscopy (flexible sigmoidoscopy or colonoscopy) with biopsies and one flexible sigmoidoscopy with biopsies that will be 6 months (+14 days) apart
- Participants must consent to refrain from using aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) or cyclooxygenase (COX)-inhibitors for the duration of the trial
- Eastern Cooperative Oncology Group (ECOG) performance status =< 1 (Karnofsky >= 70%)
- Hemoglobin >= 10 g/dL or hematocrit >= 30%
- Leukocyte count >= 3,000/microliter

- Individuals with active gastroduodenal ulcer disease in the preceding 5 years
- Individuals with any history of transfusion-dependent gastrointestinal bleeding, gastrointestinal perforation or gastrointestinal obstruction; if any of these events had been due to a malignancy of the GI tract and the malignancy has since been removed, the patient is eligible
- Individuals with history of myocardial infarction, stroke, coronary-artery bypass draft, invasive coronary revascularization in the preceding 5 years
-
Individuals taking the drugs listed below may not be randomized unless they are willing to stop the medications (and possibly change to alternative non-excluded medications to treat the same conditions) no less than 7 days prior to starting naproxen or placebo on this study; consultation with the participant's primary care provider may be obtained but is not required; the use of the following drugs or drug classes is prohibited during naproxen/placebo treatment:

- History of allergic reactions attributed to naproxen
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant, breast-feeding, or women of childbearing potential unwilling to use a reliable contraceptive method; pregnant women are excluded from this study because naproxen/NSAIDs is an agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with naproxen, breastfeeding should be discontinued if the mother is treated with naproxen
