Nanosecond Lazer Cleaning Strategy to Slow up the Surface area Inert Layer and Activate the Garnet Electrolyte for any Solid-State Li Metallic Electric battery.
Recently, several reports have described good responses to immune checkpoint inhibitors in cases where conventional chemotherapy has been unsuccessful. When predictive biomarkers of response to immune checkpoint inhibitors are identified, a combination therapy of preceding immunotherapy and subsequent surgery might provide an efficient radical therapeutic effect even in cases of unresectable advanced gastric cancer.We treated 3,164 patients with advanced cancer with dendritic cell therapy between July 2005 and March 2020. The effective rate in patients treated with dendritic cell therapy more than 3 times was 19.0%. Among them, we treated 133 cancer patients with a combination of immune checkpoint inhibitors and dendritic cell therapy between June 2015 and March 2020. find more The effective rate in these patients was 54.1%. We treated 98 cancer patients with dendritic cell therapy with neoantigens between March 2018 and March 2020. The effective rate in these patients treated with neoantigens was 38.7%. The effective rate in patients treated without neoantigens was 18.3%. Dendritic cell therapy with neoantigens enhanced the effective rate. The effective rate of dendritic cell therapy with both immune checkpoint inhibitors and neoantigens was 60.7%.We presented the case of a 63-year-old woman with severe abdominal distention due to recurrent retroperitoneal sarcoma. Further, the rapid progression of the tumor made it difficult to relieve the abdominal distention. Titrated intravenous morphine was administered. Although the dose of morphine was escalated and the patient was sedated, she continued to experience pain. The addition of a continuous epidural analgesic lidocaine to manage the abdominal distention was effective. This case report describes a stepwise approach with continuous epidural analgesia of lidocaine for a bulky tumor- related abdominal distention.An 80-year-old man who had undergone nephrectomy for renal cell carcinoma(RCC)4 years before presentation was admitted to our department for further investigation of the gallbladder tumor. The patient was diagnosed with early gallbladder carcinoma based on CT and MRI findings and treated with laparoscopic cholecystectomy. The intraoperative frozen section revealed that the identified tumor was clear cell carcinoma. Finally, morphological similarity with a previous specimen of RCC and immunostaining resulted in the diagnosis of gallbladder metastasis from RCC. Therefore, it is important to consider metastatic carcinoma of the gallbladder in the differential diagnosis of gallbladder tumors for patients with a history of renal cell carcinoma.Severe stenosis rarely occurs with radiation esophagitis after irradiation. We report our recent experience of a case of recurrent breast cancer in which the patient developed severe esophageal stenosis after receiving combined bevacizumab (Bev)-paclitaxel(PTX)therapy following radiotherapy for a thoracic vertebral metastasis. A 59-year-old woman with Stage ⅢB left breast cancer had undergone total mastectomy with axillary lymph node dissection after receiving neoadjuvant therapy. Elevated carcinoembryonic antigen levels were observed 23 months postoperatively, and multiple bone metastases were detected on PET-CT. After 5 sessions of irradiation with 20 Gy at the Th8-L1 level, combined Bev and PTX plus zoledronic acid was administered. The patient developed dysphagia at the end of the 4 cycles of combined Bev and PTX therapy, and her condition exacerbated subsequently. Therefore, upper gastrointestinal endoscopy was performed, which revealed a circumferential stenosis 31-37 cm from the incisors. We decided to perform the endoscopic treatment. After 3 balloon dilatations, her condition improved, and oral ingestion was possible. The esophageal stenosis might have been caused by the exacerbation of esophagitis because of the delayed wound healing effect of Bev in addition to radiation.A 77-year-old man was diagnosed with obstructive sigmoid colon cancer invading the psoas major and iliac muscles. To avoid the postoperative paralysis of the lower limb, a self-expandable metallic stent(SEMS)was placed, and systemic chemotherapy was administered subsequently. After 4 courses of SOX, Hartmann's procedure was performed. The patient did not develop lower limb paralysis and is alive without recurrence 2 years and 3 months postoperatively. This case suggests that preoperative metallic SEMS placement and neoadjuvant chemotherapy could be an effective treatment for locally advanced colon cancer with obstruction and invasion of the adjacent tissues.We report a case of unresectable advanced esophagogastric junction carcinoma that was treated with nab-paclitaxel and ramucirumab, which resulted in complete response and salvage surgery. A 57-year-old male complained of upper abdominal discomfort. While attending a hospital for diabetes mellitus, upper gastrointestinal endoscopy was performed. A tumor protruding from the gastric cardia to the abdominal esophagus was found, and histological examination revealed well-differentiated adenocarcinoma. Multiple liver metastases and para-aortic lymph node metastases were found on abdominal contrast-enhanced CT. The patient was diagnosed with stage Ⅳ cancer, and chemotherapy was performed as unresectable advanced esophagogastric junction carcinoma. S-1 plus CDDP therapy was started as the first-line treatment. After 2 courses of S-1 plus CDDP therapy, tumor markers were elevated. Further, the cancer was judged to be highly toxic and refractory to treatment; therefore, we started nab-paclitaxel and ramucirumab as the secondary treatment. After 4 courses, normalization of tumor markers, disappearance of liver metastases, and marked reduction of enlarged lymph nodes were observed. However, PET-CT showed increased uptake, consistent with the primary lesion. Residual cancer could not be ruled-out; therefore, total gastrectomy was performed. Histopathological examination of the surgically resected specimen showed no residual tumors.A 70-year-old man had undergone thoracoscopic esophagectomy following neoadjuvant chemotherapy for thoracic esophageal squamous cell carcinoma 3 years before presentation. He was undergoing whole-brain irradiation following surgery for a solitary brain metastatic tumor. The chief complaint was left leg pain during irradiation. FDG-PET/CT and MRI revealed metastases in bilateral cauda equina S1 nerve roots. Cerebrospinal fluid examination also revealed malignant cells. He received chemotherapy with 2 courses of 5-fluorouracil and cisplatin following 30 Gy of spinal irradiation. To control neurological symptoms, 4 courses of intrathecal chemotherapy with methotrexate, cytarabine, and betamethasone were performed. However, he gradually weakened and died 8 months after brain metastasis and 7 months after leptomeningeal carcinomatosis. The multidisciplinary treatment using irradiation and systemic and intrathecal chemotherapies could improve the survival of patients with leptomeningeal carcinomatosis of esophageal squamous cell carcinoma.
