This study is aimed to illustrate whether Radiomics combining multiparametric MRI before and after neoadjuvant chemotherapy (NACT) with clinical data is a good way to predict axillary lymph node metastasis and prognosis in invasive-breast-cancer.
This cohort study is to evaluate the role of neoadjuvant chemotherapy (NAC) in the treatment of locally advanced cervical cancer (LACC). Sixty patients with LACC (FIGO 2009 stage IB2 to IIB) will be enrolled. After informed consents, they would accept the imaging evaluation of pelvic magnetic resonance imaging (MRI) and positron emission tomography (PET). After excluding cases of distant metastasis, they will accept two cycles of NAC (paclitaxel 175 mg/m2 and cisplatin 70 mg/m2, on day 1, once for three weeks). Then a second MRI is performed to evaluate the imaging response. For patients achieving objective response, radical hysterectomy (RH, via laparoscopy or laparotomy) and an evaluation of pathologic response are performed. For patients without objective imaging response, the choice of concurrent chemoradiotherapy or radical hysterectomy will be discussed. After RH, adjuvant therapy will be given according to the RH pathologic results. The primary objectives consist of (1) the objective imaging response after NAC; (2) the objective pathologic response after RH. The secondary objectives consist of (1) disease-free survival and overall survival after various therapy modalities; (2) severe adverse effects of NAC; (3) the effects of NAC on the surgical outcomes.
The prognosis of pancreatic cancer is extremely poor. Current guidelines recommend Nab-paclitaxel, Gemcitabine and modified Folfirinox as the first-line chemotherapeutic regimen. Studies have shown that sequential chemotherapeutic regimen can effectively delay the drug resistance and improve the effect of chemotherapy. Here investigators intend to assess the effect of sequential treatment with Nab-paclitaxel plus Gemcitabine and modified Folfirinox as neoadjuvant chemotherapy for resectable pancreatic adenocarcinoma.
The investigator developed this protocol to accurately assess lymph node response to neoadjuvant chemotherapy in clinical stage N1 (cN1) breast cancer patients. Accuracy of sentinel lymph node biopsy (SLNB) alone and in combination with the removal of wire-localized-clip-marked nodes will be analyzed. New model to predict lymph node pathological complete remission (pCR) so as to safely avoid axillary lymph node dissection in cN1 breast cancer patients is sought for.
This is a single-arm, multicentre study that aims to assess whether Radiomics combining multiparametric MRI and clinical data could be a good predictor of the responses to neoadjuvant chemotherapy in Breast Cancer.
Based on multiple studies, the immune (systemic inflammation) and nutrition index were correlated with short- and long-term prognosis for gastric cancer. With the increasing application of preoperative treatments (chemotherapy and chemoradiotherapy), the issues concerning how are the immuno-nutrition index be altered under the effects of perioperative treatments and what are the clinical values of these index should be clarified.
* single center, prospective study First, evaluate the lesion under the white light endoscopy (WLE) → IV fluorescein sodium 0.1mL/kg → evaluate the lesion under probe-based confocal laser microendoscopy → target biopsy under the pCLE → random biopsy under WLE
Colorectal cancer is the fourth most common cancer in China. Up to 30% of patients with colorectal cancer present with an emergency obstruction of the large bowel at the time of diagnosis, and 70% of all malignant obstruction occurs in the left-sided colon. Patients with obstruction are associated with worse oncologic outcomes compared with those having nonobstructive tumors. Conventionally, patients with malignant large bowel obstruction receive emergency surgery, with morbidity rates of 30%-60% and mortality rates of 7-22%, and about two-thirds of such patients end up with a permanent stoma. Self-expanding metallic stents (SEMS) haven been used as a bridge to surgery (to relieve obstruction prior to elective surgery) in patients with potentially resectable colorectal cancer. Several clinical trials demonstrate that SEMS as a bridge to surgery may be superior to emergency surgery considering the short-term outcomes. SEMS is associated with lower morbidity and mortality rate, increased primary anastomosis rate, and decreased stoma creation rate. Although about half of patients can achieve primary anastomosis after stent placement, the primary anastomosis rate is still significantly lower compared with nonobstructing elective surgery. The interval between stent placement and surgery may be not long enough that bowel decompression is insufficient at the time of operation. Furthermore，the long-term oncologic results regarding SEMS as a bridge to surgery are still limited and contradictory. Sabbagh et al. suggest worse overall survival of patients with SEMS insertion compared with emergency surgery, the 5-year cancer-specific mortality was significantly higher in the SEMS group (48% vs 21%, respectively, P=0.02). One interpretation is that tumor cells may disseminate during the procedure of colonic stenting placement. We hypothesis that immediate chemotherapy after stenting may improve overall survival by eradicating micrometastasis. Moreover, neoadjuvant chemotherapy prolongs the interval between stent placement and surgery, and the time for bowel decompression is more sufficient, which may increase the success rate of primary anastomosis and decrease risk of stoma formation.
There are no standard neodjuvant regimens adapted according to the different subtypes of breast cancer. This is a phase 2, randomized study to evaluate several regimens in different subtypes of breast cancer.
