Active clinical trials for "Carcinoma in Situ"

This phase II trial studies how well abemaciclib works in treating patients with triple negative breast cancer that can be removed by surgery (resectable) and does not respond to treatment with chemotherapy alone, or in combination with pembrolizumab. Abemaciclib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This phase II trial studies how well topical afimoxifene works in treating patients with breast cancer who have undergone radiation therapy on one breast. Topical afimoxifene is a quick-drying medicated gel that may block the growth of breast cancer cells when applied to the breast skin. The purpose of this research is to determine what effect, if any, differences in skin type between women have on the delivery of topical afimoxifene to the breast tissue, and whether radiation affects the delivery of topical afimoxifene to breast tissue.

This phase Ib trial studies the side effects and best dose of a vaccine called H2NVAC before surgery in treating patients with HER2 expressing ductal carcinoma in situ. H2NVAC is a vaccine designed to stimulate specialized white blood cells in hopes of increasing immune response and protecting against breast cancer.

The purpose of this pilot study is to compare by pathological findings surgical excision versus neoadjuvant radiotherapy followed by delayed surgical excision of ductal carcinoma in situ (DCIS)

The aim of the prospective, unicenter proof-of-principle study is to investigate the anti-neoplastic effectiveness of NIPP against CIN III lesions. The aim of this project is to evaluate the potential of a previous NIPP treatment to significantly reduce the invasiveness of the LEEP excision. Another aim of this study is to investigate cellular / molecular effects of NIPP following the in-vivo treatment of the cervix using molecular biological methods. For this purpose, tissue treated with plasma is taken after defined periods of time by mini biopsy and examined using molecular biological, histological and microscopic methods.

Ductal carcinoma in situ (DCIS) accounts for approximately 20% of newly diagnosed breast cancer cases. Of these women, 20% require radical management in the form of mastectomy because of the extent of the lesions, which most often manifest as diffuse microcalcifications. This mutilating surgical management contrasts with the excellent prognosis of this pathology and considerably alters the quality of life of patients. Neoadjuvant hormone therapy has shown its efficacy in hormone-dependent infiltrating ductal carcinomas and offers the possibility of conservative surgery after hormone therapy. Adjuvant hormone therapy with Tamoxifen or anti-aromatase drugs has shown its efficacy in the prevention of homo or contralateral recurrence. The HORNEO 01 trial fits perfectly in the current context of surgical de-escalation of ductal carcinomas in situ. The objective of the study is to evaluate the impact of neoadjuvant hormone therapy on the surgical management of extensive DCIS.

This study will test a drug called enfortumab vedotin in participants with a type of bladder cancer called non-muscle invasive bladder cancer (NMIBC). This study will also evaluate what the side effects are and if the drug works to treat NMIBC. A side effect is anything a drug does to your body besides treating your disease. In this study enfortumab vedotin will be put into the bladder using a catheter. A catheter is a thin tube that can be put into your bladder.

This phase II trial studies the effect of calorie reduction while undergoing stereotactic ablative radiation therapy in treating patients with breast cancer. Stereotactic ablative radiation therapy (sABR) is a highly focused radiation treatment that gives an intense dose of radiation concentrated on a tumor, while limiting the dose to the surrounding organ. Giving SABR before surgery may make the tumor smaller. Adding dietary restrictions in combination with radiation therapy may help increase local control and decrease the spread of the cancer to other places in the body. The purpose of this trial is to identify if there is a decrease in tumor tissue in patients undergoing caloric restriction during pre-operative SABR, compared to patients undergoing pre-operative SABR alone.

This study is being conducted to evaluate the safety and determine the recommended Phase 2 dose (RP2D) of UGN-301 (zalifrelimab) administered intravesically as monotherapy and in combination with other agents in patients with recurrent NMIBC.

Although the results obtained from ECOG E5194 cohort 1 (criteria: mammographically detected low- or intermediate-grade DCIS, measuring less than 2.5 cm with margins ≥ 3 mm) and RTOG 9804 trial (the same enrolled clinicopathological features to cohort 1 of ECOG E5194 trial) demonstrated that the 7-year ipsilateral breast tumor recurrence (IBTR) ranged from 5.6% to 10.5% for low-risk ductal carcinoma in situ (DCIS) patients, the aforementioned two studies included a proportional patients who had young age and negative estrogen receptor (ER) status tumor. Previous studies and our studies revealed that age < 40 years and ER-negative status in tumor were independent prognostic factor for recurrence of breast DCIS irrespective of tumor characteristics. The UK/ANZ randomized trial, enrolling high-risk and low-risk clinicopathologic features of DCIS, demonstrated that a benefit of tamoxifen in terms of reducing the IBTR is observed in the BCS alone group but not found in the BCS plus RT group. A recent published randomized trial showed that tamoxifen at the dose of 5 mg/day for 3 years. Based on the aforementioned results, we hypothesized that the administration of tamoxifen is not inferior than the prescription of RT in terms of reducing the IBTR for DCIS patients who had age more than 40 years, the pathological features meeting the ECOG E5194 cohort 1 criteria, and positive ER status in tumors. To approve the hypothesis, we will design a randomized non-inferiority trial to assess whether the effect of administration of tamoxfien (5 mg per day) for 10 years following BCS is not inferior in terms of reducing IBTR when comparing RT following BCS for patients who had low-risk clinicopathologic features (age more than 40 years and ECOG E5194 cohort 1 criteria) and positive-ER status of breast DCIS.
