Research shows that most oral cancer patients are already locally advanced when first diagnosed. Even after surgery and radiation, nearly half of patients develop recurrence or metastasis. Even in patients who survive, there is a serious decline in quality of life due to the after-effects of surgery and radiation. Many patients therefore refuse surgery and lose the treatment opportunity. Many studies at home and abroad have found that preoperative induction chemotherapy for locally advanced tumors can reduce tumor load, reduce tumor scope, eliminate distant micro metastases, reduce the risk of recurrence and metastasis, and improve organ preservation rate. It has been confirmed in many clinical studies and our clinical practice of oral cancer MDT(Multi-Disciplinary Treatment) that induction chemotherapy with TPExtreme protocol (cetuximab + albumin-paclitaxel + cisplatin) for patients with locally advanced oral cancer can significantly reduce the tumor with a good objective response, which can create good conditions for surgery. Therefore, for patients sensitive to induction chemotherapy, there are no authoritative guidelines and clinical studies to say what is the scope of surgery. One option is for the thoroughness of the tumor resection, which is still the same as the scope of the tumor before induction therapy, but the scope of the surgery is still large, and the damage to the patient's quality of life is also serious. The other option is to perform modified radical surgery according to the scope of residual tumor lesions after induction therapy, with less trauma and less damage to the quality of life. Postoperative radiotherapy (chemical) therapy is to reduce the risk of recurrence. Our preliminary clinical practice also shows that Patients sensitive to induction chemotherapy can obtain better survival rate and quality of life after comprehensive treatment including modified radical surgery. This treatment mode is feasible, but the overall efficacy evaluation needs further study. Therefore, in this real world prospective clinical study, patients with oral cancer sensitive to induction chemotherapy will be treated with modified radical surgery or traditional radical surgery in full compliance with the patient's wishes. Through clinical observation and follow-up statistics. To explore the effects of two treatment regimens on survival rate and quality of life in order to find the best treatment mode.
This is a prospective, multicenter, exploratory study. Patients with advanced esophageal or gastro-esophageal junction squamous carcinoma who had progressed on first-line chemotherapy combined with immune checkpoint inhibitors were treated with CDK4/6 inhibitor Palbociclib combined with Afatinib. Dose titration was used to determine the final dose, and objective antitumor efficacy was evaluated every 2 cycles (8 weeks +/- 7 days) according to RECIST 1.1 criteria, until tumor progression, intolerable toxicity, death, or withdrawal of informed consent. The primary endpoint is the objective response rate (ORR).
TPF is still recommended as the preferred induction chemotherapy regimen for nonsurgical treatment of patients with LA HNSCC. Based on the KEYNOTE-048 study, all major guidelines recommend PD-1 monotherapy or PD-1 combined with chemotherapy as the new first-line standard treatment for patients with advanced HNSCC. The immunotherapy in operable LA HNSCC was also explored as neoadjuvant therapy due to the excellent data in advanced HNSCC. These explorations have also achieved good results. Therefore, this study aims to explore the pathological remission rate, the long-term benefit and safety of Tislelizumab combined with albumin paclitaxel, cisplatin and fluorouracil for locally advanced oral squamous cell carcinoma.
This is a phase II study. Twenty-three patients with locally advanced head and neck squamous cell carcinoma were planned to be enrolled to assess the efficacy and safety of neoadjuvant immunotherapy combined with radiotherapy.
01.21 SiroSkin is a phase 3, double-blind, multi-centre, parallel-arm, randomised, placebo-controlled trial to evaluate the use of topical 1% sirolimus in the chemoprevention of skin cancer, versus placebo, applied every night for 6 months in solid organ transplant recipients.
Participants of this study will have a diagnosis of a solid tumor cancer that has come back to its original location or spread beyond its original location (advanced), came back (relapsed) or worsened (refractory) after standard treatments, or no standard treatments are available for the participants' cancer. The purpose of this study if to find the highest dose of MQ710 that causes few or mild side effects in participants with a solid tumor cancer diagnosis.
This is a Phase 1b, single-center, open-label study, evaluating efficacy and safety of RP1 for the treatment of resectable cutaneous Squamous Cell Carcinoma in up to 12 evaluable patients. In this study, patients will receive RP1 via direct intratumoral (IT) injection into superficial cutaneous solid tumors to assess the safety and tolerability as well efficacy of RP1 treatment. The primary efficacy population is up to 12 evaluable patients with resectable CSCC. The enrollment of patients with CSCC will determine study duration.
Anal cancer can be prevented through detection and treatment of a recognised precancerous lesion, known as anal intra-epithelial neoplasia (AIN), specifically the anal high-grade squamous intra-epithelial lesion (aHSIL) subtype. Assessment of changes in disease burden is an important feature in the clinical evaluation of a treatment. Existing trials in aHSIL have predominantly used disease response outcomes based on histological and cytological changes to measure the effects of treatment. Several limitations to this approach have been identified. Lesion characteristics such as lesion size and number represent potential indicators of disease response to treatment and might overcome some of the limitations. We aim to develop a disease measurement instrument capable of describing disease burden such that it can be used to evaluate disease response to treatment in addition to histological and cytological based measurements further strengthening the quality of disease response outcomes. The disease measurement instrument will be developed over 4 stages: 1. A meeting of AIN experts to determine a longlist of lesion measurement items capable of capturing disease burden; 2. A series of disease assessments will be undertaken in participants known to have aHSIL to assess disease burden using the measurement items identified in stage 1; 3. Data analysis to determine the best performing measurement items and comprise a disease measurement instrument; 4. Pilot-testing of the proposed disease measurement instrument. Two trained disease assessors (experienced clinicians familiar with the assessment of anal intraepithelial lesions) will assess disease burden per participant. Disease burden will also be captured photographically. We will undertake disease assessments on 20-30 participants. By analysing the results of the clinician assessments and digital analysis of the photographic representation of disease burden, we will be able to determine the most acceptable, feasible, reliable and reproducible ways of measuring disease burden and use these to inform a disease measurement instrument.
This is an open-label, single-arm, phase II clinical trial to explore the efficacy and safety of de-escalation of postoperative radiotherapy in locally advanced head and neck squamous cell carcinoma with pathological complete response/major pathological response to neoadjuvant therapy. The eligible patients are scheduled to administered postoperative radiotherapy, PTV 50Gy/25F, instead of the standard dose of 60Gy. The overall primary study hypothesis is that reducing the dose of postoperative radiotherapy in the specific population does not affect DFS but significantly reduces treatment related adverse events.
