Filter by:This phase II trial compares the impact of subcutaneous (SC) nivolumab given in an in-home setting to an in-clinic setting on cancer care and quality of life. Currently, most drug-related cancer care is conducted in clinic type centers or hospitals which may isolate patients from family, friends and familiar surroundings for many hours per day. This separation adds to the physical, emotional, social, and financial burden for patients and their families. Traveling to and from medical facilities costs time, money, and effort and can be a disadvantage to patients living in rural areas, those with low incomes or poor access to transport. Studies have shown that cancer patients often feel more comfortable and secure being cared for in their own home environments. SC nivolumab in-home treatment may be safe, tolerable and/or effective when compared to in-clinic treatment and may reduce the burden of cancer and improve the quality of life in cancer patients.
Urothelial carcinomas are one of the most commonly diagnosed cancers worldwide. Postoperative patients carry a poor prognosis with an estimated five-year disease-specific survival rate of 50%. To improve overall survival and reduce the recurrent risk, chemotherapy is recommended as a standard of care. However, currently in Hong Kong, neoadjuvant (preoperational) chemotherapy and adjuvant (postoperative) chemotherapy are not commonly or regularly provided due to the concern of the potential harm from both physicians and patients. Recently, genetic signature from circulating tumor DNA (ctDNA) is emerging as a pivotal biomarker for detecting caner in early stage and molecular residual disease (MRD). With strengths of non-invasive and superior sensitivity, ctDNA is hopefully to serve as a cancer-agnostic surrogate analyte for risk stratification of tumor recurrence, thereby guiding individually tailored treatment. Therefore, this study is proposed to exploratively assess the benefit of ctDNA-guided approach for postoperative adjuvant therapy.
Prospective and multicenter Italian registry intended for naïve adult patients affected by locally advanced-metastatic urothelial carcinoma intended for systemic treatment, or for palliative or observation procedures
This research study involves implanting up to 4 microdevices, each small enough to fit inside the tip of a needle, into a tumor. These devices will release microdoses (many thousands of times less than a treatment dose) of different cancer drugs into the tumor. After approximately 72 hours, the devices and small regions of surrounding tissue will be removed and studied. There will be a follow-up visit within 42 days of device removal to assess for potential safety issues or side effects.
Upper tract urothelial carcinoma (UTUC) is a rare malignant disease which accounts for 5-10% of urothelial carcinoma in the western world and 9%-30% in China. About two thirds of patients have muscle invasive disease at diagnosis. Those patients usually have poor prognosis. The 5 year cancer specific survival is <50% for pT2/T3 and <10% for pT4. Radical nephroureterectomy is the standardized treatment for non-metastatic high risk UTUC. However, about half patients may suffer from impaired renal function after nephroureterectomy. On the other hand, kidney sparing surgery can avoid renal function impairment, but the therapy is only recommended for few patients with low-risk disease. The treatment for urothelial carcinoma has changed rapidly in the past few years. Immune checkpoint inhibitors and novel agents such as ADCs have shown promising therapeutic effect and were approved for patients with metastatic UTUC. Meanwhile, a recent study shows that patients with high-risk disease can also receive kidney sparing surgery without compromising cancer specific survival and overall survival. This prospective, observational study aims to evaluate the prognosis of contemporary kidney sparing surgery in patients with UTUC with or without perioperative therapy in the real world.
The purpose of this study was to compare the antitumor activity of 9MW2821 and chemotherapy in participants with locally advanced or metastatic urothelial cancer previously treated with PD-(L)1 inhibitor and platinum-containing chemotherapy.
Currently, the standard of care for female patients undergoing radical cystectomy includes the removal of the bladder, pelvic lymph nodes, anterior vagina, uterus, fallopian tubes and ovaries. Removal of female ancillary organs, both in pre and post-menopausal stages is associated with reduction in various quality of life metrics, including sexual health, cognitive decline and depression. Furthermore, removal of ovaries has been associated with increased cardiovascular events, metabolic acidosis, osteoporosis and bone fractures. In premenopausal women, the removal of the ovaries is associated with increased all-cause mortality. From an oncologic standpoint, multi institutional retrospective reviews have demonstrated certain pre-operative radiographic and cystoscopic risk factors that are associated with bladder cancer involvement of female reproductive organs. The absence of these unfavorable risk factors may provide an opportunity to spare women from undergoing unnecessary reproductive organ removal during RC. In doing so, this may eliminate the associated sequelae of removing these additional organs while also providing acceptable oncologic care. The investigators thus propose a decision tool to stratify women undergoing radical cystectomy as favorable and unfavorable for reproductive organ sparing radical cystectomy. This decision tool classification will be used to decide which patients will undergo reproductive organ sparing radical cystectomy versus radical cystectomy in this study.
This study will evaluate the efficacy and safety of RC48-ADC combined with AK104 in HER2-expression locally advanced or metastatic urothelial carcinoma.
Observational study on the quality of life and pathological state of patients underwent radical cystectomy.
Immunotherapy has been found to confer substantial survival benefits to the patients with higher mutation burdens, which become the first biomarker approved by FDA in urothelial carcinoma (UC). Nevertheless, among the patients with high mutation burdens, some still remained refractory to immunotherapy. The B7 family molecules have long been perceived as vital determinant of immune response and may define dominant molecular subsets associated with immunotherapeutic response. Simultaneously, our previous study (Eur J Cancer. 2022,171:133-142) unveiled the potential of B7-H4 as a candidate biomarker to refine the predictive capability of tumor mutation burden (TMB) in immunotherapeutic efficacy based on its significant correlation with TMB in MIBC. We hypothesized that the integration of B7 family molecules with TMB could better identify patients with better response to checkpoint blockade. In this retrospective study, a total of 1,084 UC patients from 5 independent cohorts were enrolled. We established the B7 Family Score (BFS) by the expression patterns of three B7 family members: PD-L1 (CD274), B7-H3 (CD276) and B7-H4 (VTCN1) based on protein and transcriptomic level respectively. We further investigated the correlation of BFS with genomic features and therapeutic response in UC. In addition, we integrated the BFS with tumor mutation burden (TMB) to better stratify the clinical benefit from PD-L1 blockade and platinum-based chemotherapy.
