Project description:BackgroundThe frequency of arrhythmias increases after the Fontan operation over time; atrial tachycardia (AT) and sinus node dysfunction (SND) are frequently observed.Case summaryOur patient was 63-year-old woman who underwent a lateral tunnel Fontan operation for double outlet right ventricle at age 36. She experienced paroxysmal AT for 1 year, and antiarrhythmic medication was not feasible due to symptomatic SND. Computed tomography revealed a 45 mm-sized thrombus in the high right atrium (RA). The patient had three coexisting conditions: paroxysmal AT, symptomatic SND, and the right atrial thrombus, for which total cavopulmonary connection conversion and epicardial pacemaker implantation (PMI) would have been effective; however, given her age and comorbidities, surgical treatment was considered high risk. Catheter ablation was avoided because of the right atrial thrombus. Finally, a transvenous pacemaker was implanted via the right femoral vein to avoid the right atrial thrombus and severe venous tortuosity from the left subclavian vein to the RA. After PMI, the patient was prescribed amiodarone and bisoprolol for AT suppression. Atrial tachycardia occurred once in the third month after discharge. We increased the dose of amiodarone, and she has been tachycardia-free.DiscussionTransvenous PMI must be considered in cases where open thoracic surgery or catheter ablation cannot be performed. This is the first report of transvenous PMI via the right femoral vein and successful AT and SND management in an elderly Fontan patient.

Project description:BackgroundImmune checkpoint inhibitors were used for patients with advanced non-small cell lung cancer (NSCLC) more and more frequently and the effects were thrilling. Toripalimab as a new immune checkpoint inhibitor has been shown to be effective in patients with advanced NSCLC. However, data regarding the safety and feasibility of surgical resection after treatment with toripalimab for NSCLC remain scarce. Here, we present a case with locally advanced NSCLC that received video-assisted thoracic surgery (VATS) lobectomy after treatment with toripalimab in combination with chemotherapy.Case presentationA 62-year-old male patient with a history of coronary artery stenting operation for two times was found a 3.4 × 3.2 cm cavity mass in the upper lobe of the left lung and enlarged left hilar and mediastinal lymph nodes. Pathological results identified squamous cell carcinoma. The patient was diagnosed with a locally advanced NSCLC and received VATS left upper lobectomy and lymph node dissection after neoadjuvant chemotherapy plus toripalimab for 3 cycles. The postoperative pathological results showed complete tumor remission. Short-term follow-up results were excellent, and long-term results remain to be revealed.ConclusionsOur preliminary results showed that the use of neoadjuvant toripalimab and chemotherapy for the locally advanced NSCLC before surgical resection is safe and feasible.

Project description:Accurate diagnoses are crucial in determining the most effective treatment across different cancers. In challenging cases, morphology-based traditional pathology methods have important limitations, while molecular profiling can provide valuable information to guide clinical decisions. We present a 35-year female with lung cancer with choriocarcinoma features. Her disease involved the right lower lung, brain, and thoracic lymph nodes. The pathology from brain metastasis was reported as “metastatic choriocarcinoma” (a germ cell tumor) by local pathologists. She initiated carboplatin and etoposide, a regimen for choriocarcinoma. Subsequently, her case was assessed by pathologists from an academic cancer center, who gave the diagnosis of “adenocarcinoma with aberrant expression of β-hCG” and finally pathologists at our hospital, who gave the diagnosis of “poorly differentiated carcinoma with choriocarcinoma features”. Genomic profiling detected a KRAS G13R mutation and transcriptomics profiling was suggestive of lung origin. The patient was treated with carboplatin/paclitaxel/ipilimumab/nivolumab followed by consolidation radiation therapy. She had no evidence of progression to date, 13 months after the initial presentation. The molecular profiling could facilitate diagnosing of challenging cancer cases. In addition, chemoimmunotherapy and local consolidation radiation therapy may provide promising therapeutic options for patients with lung cancer exhibiting choriocarcinoma features.

Project description:A 74-year-old man with lung adenocarcinoma recurrence was admitted to our hospital because of dyspnea 7 days after receiving initial immunotherapy with nivolumab. Electrocardiography revealed ST-segment elevation in V1-6 and echocardiography showed a markedly reduced left ventricular ejection fraction of 9% and akinesis of the anteroseptal wall and apex. He died from acute heart failure 3 days after admission. Microscopically, multiple small foci of myocardial necrosis with few inflammatory cells were scattered in both ventricles. Obstruction of the coronary artery was not identified. We believed that the cause of death was acute heart failure possibly due to nivolumab-induced myocardial necrosis.

Project description:Immune checkpoint inhibitors (ICIs) became the standard treatment for many different kinds of cancers and can result in a variety of immune-related adverse events (irAEs). IrAEs of kidney are uncommon and consists of different pathology types. Among the different types, membranous nephropathy (MN) is rare and have not been well-described. Since MN can also be associated with malignancies, differential diagnosis in patients receiving ICIs who develop MN can be very difficult. We present the case of a 74-year-old man with metastatic non-small cell lung cancer who developed MN after ICIs therapy. The patient tested positive for thrombospondin type-1 domain-containing 7A antibodies (THSD7A) when diagnosed with MN. Supplementary examinations revealed the predisposing antigen in the primary tumor and present of the antibody after immunotherapy, which corresponded to the patient's clinical course of nephropathy. Treatment consisting of systemic glucocorticoids and rituximab resulted in a good clinical response, and the THSD7A antibodies were no longer detected. In this case, we first discuss the potential mechanism of immunotherapy related MN, in which the activation of humoral immunity may play an important role.

Project description:Drainless video-assisted thoracoscopic (VATS) wedge resection has been demonstrated as feasible in treating various lung diseases. However, it remains unknown whether this surgical technique can be effectively applied to lobectomy. In the current study, we evaluated the perioperative outcome of drainless, minimally invasive lobectomy in patients with lung cancer. A total of 26 lung cancer patients who received surgery-performed pulmonary lobectomy were enrolled. The perioperative outcomes were analyzed based on a propensity score matching a comparison with those who had chest drainage. No major surgical morbidity and mortality was noted during the perioperative period. The mean of postoperative hospital stay was 5.08 ± 2.48 days. There was no significant difference in postoperative hospital stay between the two groups of patients. However, the presence of significant postoperative pain (VAS score > 30) on the first day after surgery was less in the drainless group (34.6% vs. 3.8%; p = 0.005). Our results demonstrated that drainless, minimally invasive lobectomy for selected lung cancer patients is feasible. Further evaluation of its impact on short- and long-term surgical outcomes is required in the future.

Project description:BackgroundChemotherapy and radiotherapy followed by durvalumab is currently the standard treatment for locally advanced node-positive non-small-cell lung cancer (NSCLC). We describe the case of a patient with locally advanced node-positive NSCLC (LA-NSCLC) treated in a phase II prospective protocol with chemotherapy, accelerated hypofractionated radiotherapy (AHRT) and surgery in the pre-immunotherapy era.Case summaryA 69-year-old male, ex-smoker (20 PY), with a Karnofsky performance status of 90, was diagnosed with locally advanced squamous cell lung carcinoma. He was staged by total body computed tomography (CT) scanning, and integrated 18F-fluorodeoxyglucose positron emission tomography/CT scan [cT4 cN3 cM0, stage IIIC according to TNM (tumor-node-metastasis) 8th edition] and received AHRT between chemotherapy cycles, in accordance with the study protocol (EudractCT registration 2008-006525-14). At the end of the study the patient underwent surgery, which was not part of the protocol, and showed a complete pathological response.ConclusionThis case report confirms that AHRT can be used successfully to treat primary LA-NSCLC with bilateral mediastinal lymph node involvement. Our case is of particular interest because of the pathological response after AHRT and the lack of surgical complications. We hypothesize that this radiotherapeutic approach, with its proven efficacy, could be delivered as a short course reducing treatment costs, increasing patient compliance and reducing toxicity. We are currently investigating the possibility of combining hypofractionation, chemotherapy and immunotherapy for patients with LA-NSCLC.

Project description:We report clinical and genetic findings of a 14-year-old male with T-cell acute lymphoblastic leukemia with low-hypodiploidy. The medical history included neck pain for a month, facial nerve palsy on the right side for 6 days, fever, drowsiness, and weakness for 3 days, vomiting, diarrhea for 1 day. The physical examination presented features of hypovolemia, palsy of the facial nerve on the right side, enlarged lymph nodes, hepatosplenomegaly, sore throat, and petechiae of the skin. Radiological images indicated lesions of different organs. Bone marrow biopsy confirmed precursor T-ALL. In the FISH tests, KMT2A and BCR/ABL1 rearrangements were not observed. GTG banding revealed 3 cell clones, which confirmed the hypodiploidy. Multiplex RT-qPCR was performed. STIL/TAL1 (del1p32) gene rearrangement was found in the blast cells. Additional tests were performed using the CytoScan HD microarray technique. Molecular karyotype did not reveal hypodiploidy, but identified other abnormalities such as duplication of chromosomal regions: 4q25q35.2, 6p23.3p11.1 and 8p23.3q24.21, and the loss of heterozygosity of short arm chromosome 9. In two regions of the chromosome biallelic deletions were found at 9p21.3, including the CDKN2A, CDKN2B, IFNA1, MTAP genes and at 10q23.31, containing PTEN. The child died 9 days after diagnosis. Bone marrow biopsy, GTG banding, FISH techniques, and molecular karyotyping were used to make an accurate diagnosis. This case documents a rapid progression of the disease and unfavorable results of T-cell acute lymphoblastic leukemia with hypodiploidy.

Project description:Dabrafenib plus trametinib is US Food and Drug Administration approved combination therapy for use in patients with BRAF V600E-mutant non-small cell lung cancer, but information on use outside of clinical trials is limited. We report the case of a 70-year-old Asian woman (never smoker) who was diagnosed with lung adenocarcinoma in May 2014. Testing at diagnosis was negative for programmed death ligand 1 or EGFR, ALK, and ROS1 alterations. She was started on carboplatin-pemetrexed-bevacizumab and maintenance bevacizumab but progressed in September 2015. Subsequently, she progressed on second-line nivolumab and third-line docetaxel. In March 2016, pleural fluid obtained at diagnosis tested positive for the BRAF V600E mutation and she received dabrafenib plus trametinib. She experienced rapid tumor shrinkage and symptom improvement and became able to participate in regular daily activities with no notable adverse events. In December 2016, she died from a hemorrhagic stroke considered unrelated to treatment. In this heavily pretreated patient with non-small cell lung cancer, dabrafenib plus trametinib elicited an excellent response.
