Effect of Meal Timing During Cancer Treatment in Patients in Alaska: A Randomized Clinical Trial

The goal of this clinical trial is to test meal-timing as a novel and sustainable interventional approach during cancer treatment to improve therapeutic response and metabolic health in an understudied population. This clinical trial will enroll patients with rectal or breast cancer receiving neoadjuvant treatment at the Alaska Native Medical Center (ANMC), which is part of the Alaska Native Tribal Health Consortium (ANTHC). A promising strategy for improving the efficacy of anticancer treatments and reducing associated toxicities involves combining treatment with fasting regimens. In pre-clinical and clinical studies, various forms of fasting have been shown to induce tumor regression and improve long-term survival. According to the differential stress sensitization theory, fasting is thought to sensitize tumor cells to the cytotoxic effects of chemotherapy and radiation, while protecting healthy cells by increasing stress resistance. While healthy cells slow their growth and become more stress resistant in response to fasting, cancer cells cannot survive in nutrient-deficient environments; although the underlying mechanisms are not fully understood. However, extended water-only fasting can be challenging for patients and poses undue health risks. Intermittent fasting, and specifically time-restricted eating (TRE), may offer a viable alternative. TRE involves eating within a shorter window (e.g., 8 hours) and fasting for the remainder of the day but involves no other dietary restrictions. Because of its simplicity, TRE may be more sustainable than other fasting regimens. TRE also improves several cardio-metabolic endpoints, including insulin sensitivity, which may also be beneficial during anticancer treatments.

Capecitabine in ER+/HER2-negative Breast Cancer

This is a Phase 2 study for patients with resected Stage I-III HR+/HER2-negative breast cancer with detected molecular residual disease (MRD+) following standard neo/adjuvant and locoregional therapy delivered with curative intent. In this study participants will be treated with capecitabine. Capecitabine will be administered orally at a dose of 500 mg 3 times daily for up to 12 months, or until the time of clinical recurrence, discontinuation due to toxicity, or withdrawal of consent. This study will have two stages, stage 1 would enroll up to 8 participants to clear the Minimal Residual Disease (MRD) and Stage 2 will enroll up to 5 participants. The purpose of this study is to determine if this study population would have a better outcome from receiving capecitabine rather than having no change in treatment if MRD is detected.

CRYO-1: Cryoablation in Elderly Patients With Early-Stage Breast Cancer.

This study looks at a new way to treat early-stage breast cancer in older adults using a freezing technique called cryoablation. Older adults with early-stage breast cancer are usually treated with surgery or primary endocrine therapy (hormone therapy). While these treatments can be effective, they may also be burdensome. Surgery can lead to pain, slow recovery, or complications, and primary endocrine therapy often requires long-term medication and may cause side effects or stop working over time. Cryoablation may offer a less invasive treatment option. The goal of this study is to find out whether cryoablation can be safely and successfully used as the main treatment for older adults with early-stage breast cancer. Cryoablation destroys the tumour by freezing it. The procedure is performed through the skin using imaging guidance and does not involve surgical removal of the tumour. Participants in this study are adults aged 70 years or older who have a small breast tumour that has not spread to the lymph nodes. All participants receive cryoablation as a single treatment. After the procedure, participants are followed closely. Researchers will collect information on side effects, recovery, whether additional treatment is needed, and how participants experience the treatment. Quality of life will also be assessed. This study is carried out in several hospitals. All participants must give written informed consent before taking part. The results of this study may help determine whether cryoablation could be a safe and practical treatment option for older adults with early-stage breast cancer and guide future research.

Role of Triggering Receptor Expressed on Myeloid Cells (TREM-1) as a Novel Biomarker in Human Epidermal Growth Factor Receptor -2 (HER-2) Negative Breast Cancer: a Molecular and Clinical Study

Global cancer statistics by world region for the year 2022 estimated breast cancer the 2nd cause of new cancer cases (11.6%). (1) Approximately 80% of all breast cancers (BCs) are currently categorized as human epidermal growth factor receptor 2 (HER2)-negative. (2) Most breast cancer cases can be cured by multimodality treatment, although cure rates vary by clinical stage, subtype and the clinical behavior of cancer which affected by the composition of pro- and anti-tumor immune mediators within the tumor microenvironment. (3, 4) Immune gene signatures in breast tumors -that comprise genes with specialized roles in immune biology- Significantly, have been shown to correlate with patient survival outcomes. (5-8)chemotherapy responsiveness. (7, 9), and more recently, response to immunotherapies.(10-12)One such candidate, the gene encoding Triggering Receptor Expressed on Myeloid Cells (TREM)-1, which emerged as a robust therapy predictive and prognostic marker. TREM1 encodes a type I trans-membrane receptor of the Ig superfamily expressed by effectors of innate immunity including neutrophils, monocytes and macrophages. The TREM-1 receptor is known to augment inflammatory signaling in response to infectious pathogens by promoting release of cytokines that modulate the activation, recruitment and survival of myeloid and lymphoid cells. (13) In this study we hope to gain a better understanding of TREM-1 clinical and molecular relevance in HER2 negative BC either triple negative or hormonal positive which represent significant subset that lack target therapeutic options, evaluating its effect as predictive and prognostic marker and so the potential implications for patient management.

Ways of Retaining the Inframammary Fold in Implant-based Breast Surgery

There is currently no consensus on the "gold standard" for Implant-based Breast reconstruction. In the United States, more than half of all breast reconstructions are performed using acellular dermal matrix (ADM). However, based on the findings of literature and systematic reviews, it can be cautiously said that synthetic meshes cause fewer complications with comparable aesthetic results and low cost. In our study, we propose using polytetrafluoroethylene (PTFE) mesh in implant-based breast reconstruction. This material has previously proven itself in cardiovascular, maxillofacial and neurosurgery, hernioplasty and as a suture material. Allogeneic dura mater, which has demonstrated comparable results in breast reconstruction with the literature, will be used as a comparison. The purpose of this study is to evaluate the efficacy and safety of a porous, non-biodegradable, synthetic polytetrafluoroethylene mesh for implant-based breast reconstruction in patients diagnosed with breast cancer. An allogeneic dura mater technique will be used as a control. Patients eligible for this study are classified according to the National Comprehensive Cancer Network (NCCN) guidelines as having stage 0-2 breast cancer. The primary questions this study aims to answer are: * What are the rates of major and minor complications associated with these techniques. Major complications will be defined as complications leading to reoperation. * How effective are PTFE mesh and dura in maintaining the inframammary fold and implant projection after breast reconstruction? * What is the patient satisfaction rate with the surgical results? Patients will be randomly assigned to the study but will know which technique will be used in their particular case. Patients included in this study will undergo subcutaneous mastectomy or skin-sparing mastectomy using standard techniques with simultaneous implantation using PTFE mesh or allogeneic dura mater graft. In our opinion, the mesh and graft will stabilize the projections of the inframammary fold and breast implant. After the surgery, all minor and major complications will be recorded for 6 months. For this, both physical examination and radiological diagnostic methods will be used, including breast ultrasound and MRI with contrast. Revision surgeries will be performed if necessary. Projections of the inframammary fold and breast implant will also be measured in order to determine the effectiveness of the compared techniques. Patients will be asked to complete the BREAST-Q Version 2.0© Reconstruction Module questionnaire to determine satisfaction with the surgical outcome. The results of the study will help the professional community to determine the most effective method of Implant-based Breast reconstruction and will be published in peer-reviewed scientific journals.

Evaluation of Radiobiological Effects in Skin Toxicities for Breast Cancer Patients With Pencil Beam Scanning Proton Therapy

This purpose of this study is to examine skin reactions (called radiation dermatitis) that occur during pencil beam scanning (PBS) proton therapy. The researchers will test a unique technique called "Spot Delete" to see if it can reduce skin reactions for breast patients treated with PBS. They will also use a special computer model to study how the energy of the proton beam (linear energy transfer) is related to these skin reactions. The study involves creating a treatment plan based on a CT scan, which helps guide the proton beam in the body. The clinical team uses this CT scan to find the best placement for the protons. The "Spot Delete" method prevents protons from stopping in the skin, which is thought to cause skin redness.

Adjuvant Pyrotinib and Capecitabine For HER2 Positive Micro Invasive Breast Cancer

For patients with HER2-positive early-stage breast cancer, NCCN guidelines recommend chemotherapy plus targeted therapy as the standard adjuvant treatment for patients with tumors larger than 1 cm or lymph node-positive. The APT study enrolled patients with stage I HER2-positive breast cancer and has confirmed the efficacy and safety of intravenous chemotherapy combined with targeted therapy, but only 2.2% of the patients enrolled in microinvasion are enrolled, and there is a lack of large sample size data to provide a treatment reference for these patients. In order to further explore the optimal strategy for adjuvant therapy in this type of patient, we designed a new clinical trial to evaluate the efficacy and safety of oral capecitabine plus pyrotinib as adjuvant therapy in previous retrospective studies.
