Carcinoma Of The Pancreas

Primary squamous cell carcinoma of the pancreas is a rare malignant neoplasia, accounting for approximately 0.5–2% of all malignant pancreatic tumors. These lesions are characterized by poor prognosis. Here we report on a case of a 57-year-old female patient with knownBRCA2germline mutation presenting with primary squamous cell carcinoma of the pancreas as the only malignancy. The tumor was locally advanced at the first presentation but responded almost completely to neoadjuvant radio-chemotherapy. Our case highlights the facts (i) that pancreatic carcinomas belong to the tumor spectrum of patients with theBRCA2-associated hereditary breast and ovarian cancer syndrome (HBOC) and (ii) that tumors of the pancreas can represent the first or even the only manifestation of HBOC. Furthermore, this case of a nonkeratinizing squamous cell carcinoma indicates that HBOC-associated carcinomas of the pancreas might be characterized by a broader morphological spectrum than was previously thought. SinceBRCAmutations cause deficiency of DNA double-strand breakage repair in tumors, neoadjuvant treatment regimens might become a reasonable option in HBOC-associated pancreatic carcinomas. To our knowledge, this is the first reported case of a primary pancreatic squamous cell carcinoma in a patient with this particular genetic background ofBRCA2-associated HBOC.

e16029 Background: Compared with neoadjuvant chemotherapy alone，Neoadjuvant radiochemotherapy can significantly increase pCR rate in esophageal squamous cell carcinoma and improve patient overall survival. However, the addition of radiotherapy increases the risk of adverse reactions and surgery. Neoadjuvant radiochemotherapy is currently used in < 5% of Chinese patients.The purpose of this phase II study is to assess the efficacy and safety of toripalimab combined with paclitaxel and cisplatin as neoadjuvant treatment for resectable locally advanced esophageal squamous cell carcinoma(clinical trial registration number: ChiCTR1900025318). Methods: Patients 18–75 years old with esophageal squamous cell carcinoma confirmed by endoscopic biopsy, assessed to be locally advanced esophageal squamous cell carcinoma (cT1–cT2, N+; cT3–cT4 a, any N), and expected to be resectable were given toripalimab (240 mg d1 + PTX 175 mg/m2 + PDD 75 mg/m2 q3w) before surgery for two treatment cycles, followed by efficacy assessment. A consultation meeting with thoracic surgeons was held to assess radical surgery for patients with resectable lesions 4–6 weeks after neoadjuvant therapy was completed. pCR and postoperative-stage statistical analysis were conducted based on postoperative pathology test results. These results were used to determine the efficacy and safety of PD-1 monoclonal antibody combined with chemotherapy as neoadjuvant therapy for locally advanced esophageal cancer. Results: By December 2020, 23 subjects were enrolled. Of the subjects, five withdrew without undergoing surgery (three subjects refused surgery and switched to radical radiochemotherapy, one subject progressed to PD after two cycles of neoadjuvant therapy and switched to palliative treatment, and one subject could not undergo surgery after neoadjuvant treatment and gave up the treatment) and 18 evaluable patients underwent surgery. The R0 resection rate was 100%, and T0–Tis 33.3% (6/18) achieved pCR. Among these patients, 61.1% (11/18) achieved T0–T1 after surgery, and 72.2% (13/18) achieved N0. Moreover, stage reduction effects were significant compared with preoperative TN staging. Common side-effects include nausea, vomiting, neutropenia, thrombocytopenia, rash, asthenia, constipation, and muscle soreness. Most adverse events were grades 1–2, and grades 3/4 adverse events include one case of grade 3 neutropenia and one case of grade 3 diarrhea (suspected immune-related colitis), which improved after symptomatic treatment. Conclusions: Toripalimab combined with the TP scheme showed preliminary efficacy and controllable safety in the treatment of resectable locally advanced esophageal squamous cell carcinoma and is worthy of further exploration. Clinical trial information: ChiCTR1900025318.

e16033 Background: Camrelizumab has been approved as a standard therapy in the second-line treatment of esophageal squamous cell carcinoma (ESCC). This study aimed to explore the efficacy and safety of camrelizumab combined with commonly used neoadjuvant chemotherapy (paclitaxel and platinum) in neoadjuvant treatment of ESCC. Methods: In this single-arm, phase Ⅱ study, patients with advanced ESCC who were expected to receive neoadjuvant therapy followed by radical surgery were recruited. The patients received 2-4 cycles of camrelizumab (200mg, iv, q3w) in combination with paclitaxel (155mg/m2, iv, q3w) and nedaplatin (80mg/m2, iv, q3w) as neoadjuvant therapy, and the therapeutic effects were determined every 2 cycles. The radical surgery was performed on patients whose tumors were evaluated as resectable. The primary endpoint was pCR, and the secondary endpoints were objective response rate (ORR) and disease control rate (DCR). Results: From May 2020 to January 2021, 24 patients with a median age of 60.5 years (50-73) were enrolled. Among them, 21 patients were available for efficacy analysis, of which 1 achieved complete response (CR), 7 achieved partial response (PR), and 13 had stable disease (SD). The ORR was 38.1% and DCR was 100%. The tumor in 10 patients shrank significantly after neoadjuvant therapy and these patients preferred radiotherapy instead of surgery as the radical therapeutic method. 2 patients abandoned surgery because of personal reasons. 2 patients were in the process of neoadjuvant therapy and had not undergone surgery yet. The remaining 7 patients underwent radical surgery and 4 patients (57.14%) achieved pCR (pT0N0M0). The main treatment-related grade 3/4 adverse event (AE) was neutropenia (1/21). All the AEs were manageable. The average intraoperative blood loss was 221mL and the average hospitalization time after operation was 12.7 days (range 8-19 days). No anastomotic leakage and treatment-related death occurred. Conclusions: Camrelizumab in combination with paclitaxel and platinum as a neoadjuvant therapy was well tolerated. The pCR rate of 57.14% was higher than the expected 40%. This encouraging result promoted us to continue this phase Ⅱ study. Clinical trial information: ChiCTR2000033761.

Carcinoma Squamous Cell

Primary pancreatic squamous cell carcinoma is sporadic. The diagnosis is usually made following surgery or needle biopsy and requires a thorough workup to exclude metastatic squamous cell carcinoma. Squamous cell carcinoma of the pancreas often has a very poor prognosis. There is no treatment guideline for this type of cancer, and to date, no therapeutic regimen has been proven effective. Here, we report the effectiveness of immunotherapy in combination with chemotherapy against locally advanced squamous cell carcinoma of the pancreas with high programmed cell death ligand 1 (PD-L1) expression. Regional intra-arterial infusion chemotherapy consisting of nab-Paclitaxel followed by gemcitabine infused via gastroduodenal artery every three weeks for two cycles. This therapy resulted in the depletion of carcinoma, and the patient continues to lead a high-quality life with no symptoms for more than 16 months.
