Adjuvant Chemotherapy

Adjuvant chemotherapy was unnecessary in pathological stage Ⅱ colorectal cancer following initial treatment of surgery without high risk factors of recurrences. The treatment efficacy of adjuvant chemotherapy for pT1-3N0M0 colorectal cancer following preoperational chemotherapy or chemoradiotherapy remains unclear. Part of clinical local advanced colorectal cancer(cTxN1-2M0), which turn out to be pT0-3N0M0 after preoperational chemotherapy or chemoradiotherapy, might not really need adjuvant chemotherapy due to the down-stage efficacy of the preoperational treatments, or the misleading by lymph nodes false-positive imaging diagnosis.

To find out if a combination of fruquintinib and tislelizumab can control CRC in patients who have received treatment for the disease but still have "positive" ctDNA tests for MRD (meaning there is evidence of MRD based on this test).

This study will utilize ctDNA methylation detection to evaluate patients with stage I or low-risk stage II colorectal cancer who are ctDNA-positive one month after surgery. It aims to investigate the impact of different adjuvant chemotherapy regimens on ctDNA clearance rates and their prognostic significance. By using postoperative ctDNA status to identify patients at high risk of recurrence, the study seeks to implement intensified chemotherapy strategies (treatment escalation) at an early stage, thereby improving ctDNA clearance and ultimately enhancing patient outcomes.

This is a multicenter, open-label, phase 3, randomized, non-inferiority study aimed to investigate the effect on disease-free survival of adjuvant chemotherapy with oxaliplatin plus S-1 compared with adjuvant chemotherapy with docetaxel plus S-1 after D2 gastrectomy in patients with stage III gastric cancer.

This study aims to investigate the efficacy and safety of neoadjuvant cadonilimab in combination with perioperative SOX chemotherapy, compared to perioperative SOX chemotherapy alone, in patients with diffuse or mixed-type locally advanced gastric or gastroesophageal junction adenocarcinoma. The main questions it seeks to answer are: 1. Is neoadjuvant cadonilimab plus SOX chemotherapy superior to neoadjuvant placebo plus SOX chemotherapy in terms of the pathological complete response (pCR) rate at the time of surgery? 2. To evaluate and compare the 3-year OS rate in patients receiving neoadjuvant cadonilimab plus SOX chemotherapy versus patients receiving placebo plus neoadjuvant SOX chemotherapy regimen. Participants will be divided into two groups: 1. Experimental group: Participants will receive intravenous cadonilimab (10 mg/kg) in combination with the SOX regimen (oxaliplatin 130 mg/m² and S-1, with the initial dose determined based on body surface area). 2. Control group: Participants will receive a placebo in combination with the SOX regimen. After completing 3-4 cycles of treatment, patients in both the experimental and control groups will undergo radical surgery with D2 or D2+ lymphadenectomy. Following surgery, patients will receive 4 cycles of adjuvant SOX chemotherapy at 70% of the standard dosage, administered every 21 days, starting within 3-6 weeks post-surgery.

This study aims to compare the efficacy and safety of neoadjuvant apatinib combined with sintilimab and perioperative SOX chemotherapy versus neoadjuvant sintilimab combined with perioperative SOX chemotherapy in locally advanced intestinal-type gastric cancer/gastroesophageal junction adenocarcinoma. The primary questions include: 1. Whether the complete remission rate (pCR) of the apatinib combined with sintilimab and SOX regimen is higher than that of the sintilimab combined with SOX regimen. 2. The safety of the apatinib combined with sintilimab and SOX regimen. Participants will be divided into: 1. Experimental Group: Participants will receive an intravenous injection of sintilimab (200 mg) combined with the SOX regimen (oxaliplatin 130 mg/m² and S-1, with the initial dose determined based on body surface area). Additionally, apatinib (250 mg) will be administered orally once daily during the first three neoadjuvant cycles. 2. Control Group: Participants will receive treatment with the sintilimab combined with the SOX regimen. This treatment will be administered for three to four cycles prior to surgery, followed by radical surgery, including D2 or D2+ lymph node dissection. Surgery is scheduled four weeks after the last neoadjuvant therapy (NAT) cycle. Within 3 to 6 weeks post-surgery, patients will begin adjuvant SOX chemotherapy. Postoperative patients will receive four cycles of adjuvant SOX chemotherapy, administered every three weeks.

This study is designed to evaluate the safety and efficacy of adjuvant FOLFIRINOX regimen in pancreatic cancer patients after curative surgery.

This study carried out a prospective, randomized, controlled clinical study under the background of intensity-modulated radiation therapy and three-dimensional afterloading therapy. By comparing simultaneous intensity-modulated radiotherapy and chemotherapy combined with adjuvant chemotherapy and simultaneous intensity-modulated radiotherapy and chemotherapy alone, based on the 2018 FIGO staging The clinical efficacy of locally advanced cervical cancer further clarifies the role of adjuvant chemotherapy in locally advanced cervical cancer.
