Multi-points and Full-thickness Biopsy in the Diagnosis of cCR After Neoadjuvant Therapy for Rectal...
Rectal CancerNeoadjuvant Therapy2 moreBackground There is currently no reliable means to restage rectal cancers after neoadjuvant chemoradiation. There are still no reliable methods to identify patients with pCR before radical surgery. As a result, clinical complete response (cCR), defined as no clinical detectable tumor by physical examination, endoscopic evaluation, and imaging, is designed as a surrogate endpoint for pCR. However, the concordance between cCR and pCR varies from 22% to 96% in different reports, which questions the clinical value of such strategies. Therefore, based on rectal diginal examination, serum CEA, MRI, endoscopy examination, we suggested to add multi-points and full-thickness biopsy technique to further improve the accuracy of cCR.
Heated Intra-peritoneal Chemotherapy With Doxorubicin and Cisplatin for the Treatment of Resectable,...
Malignant Abdominal NeoplasmMalignant Pelvic Neoplasm25 moreThis early phase I trial studies how well heated intra-peritoneal chemotherapy with doxorubicin and cisplatin work for the treatment of abdominal or pelvic tumors that can be removed by surgery (resectable), does not respond to treatment (refractory), or has come back (recurrent). Heated intra-peritoneal chemotherapy is a procedure performed in combination with abdominal surgery for cancer that has spread to the abdomen. It involves the infusion of a heated chemotherapy solution that circulates into the abdominal cavity. Chemotherapy drugs, such as doxorubicin and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Heating a chemotherapy solution and infusing it directly into the abdomen may kill more cells.

Neoadjuvant Arterial Embolization Chemotherapy Combined PD-1 Inhibitor for Locally Advanced Rectal...
Rectal NeoplasmsRectal cancer is one of the common malignant tumors of the digestive tract. Some patients with rectal cancer are already advanced tumors when they are first diagnosed. At this time, the tumor has local infiltration, the probability of recurrence and metastasis after surgical resection is high, and even radical tumor resection cannot be performed. Neoadjuvant chemotherapy and radiotherapy have become one of the important treatment methods for these patients to increase the rate of radical tumor resection. However, a series of side effects of neoadjuvant radiotherapy can even continue after the end of radiotherapy, and even increase the incidence of postoperative complications. Superselective arterial interventional chemotherapy has been widely used in preoperative neoadjuvant chemotherapy for various tumors, and its efficacy in rectal cancer has also been confirmed. In addition, as a hot spot in tumor treatment, tumor immunotherapy has shown exciting effects in the NICHE study of neoadjuvant immunotherapy before colon cancer surgery. Moreover, Oxaliplatin is a classic chemotherapeutic drug that induces Immunogenic cell death effects, which induce antitumor immunity. Therefore, in order to optimize the preoperative neoadjuvant therapy plan, the investigators propose a treatment method of superselective arterial chemoembolization combined with immunotherapy and systemic chemotherapy, in order to obtain better preoperative conversion therapy effect and reduce the adverse reactions of neoadjuvant therapy.
SMART TNT for the Conservative Management of Locally Advanced Rectal Cancer
Locally Advanced Rectal CancerThe purpose of this research study is to find out how safe and effective is treating patients with locally advanced rectal cancer (LARC) with chemotherapy first and then follow with radiation therapy to a higher dose than what is usually delivered and see if patients could have complete response and be spared from surgery.
