Prolonged fever is a common symptom of COVID-19 infection. However, other febrile diseases continue during the pandemic. Herein, we report a COVID-19-infected patient with prolonged fever despite the lack of oxygen requirement, who was finally diagnosed with tuberculotic lymphadenitis and HIV-1 infection. All symptoms improved rapidly after the initiation of antituberculosis medications. Tuberculosis is an important differential diagnosis for patients with prolonged fever during the COVID-19 pandemic. It is possible that COVID-19 infection could serve to unmask latent infections via a cytokine storm.
Eribulin mesylate (eribulin) is a nontaxane microtubule inhibitor approved in Japan for treating soft tissue sarcoma irrespective of histological subtypes. Thus, our department routinely uses eribulin to treat any histological subtype of sarcoma for patients who have experienced disease progression during standard therapy. However, evidence on the efficacy of eribulin in treating sarcomas that are neither liposarcoma nor leiomyosarcoma is limited. Recently, we encountered a case of a heavily pretreated cardiac angiosarcoma that responded well to eribulin treatment. The patient was a 34-year-old Japanese woman with advanced angiosarcoma, who had been pretreated heavily using several lines of chemotherapy. Eribulin was administered as the eighth line of treatment and the dose was adjusted because of grade 4 neutropenia. After three cycles of treatment, contrast-enhanced computed tomography showed a partial tumor response, which was sustained for ~4 months. This case suggests that eribulin may be a potential therapeutic option for angiosarcoma. Further studies are needed to confirm the benefit of eribulin for patients with angiosarcoma and to establish predictive markers for eribulin sensitivity.
<div>AbstractPurpose:<p>Sentinel lymph node biopsy (SLNB) is the gold-standard procedure for evaluating axillary lymph node (ALN) status in patients with breast cancer. However, the morbidity of SLNB is not negligible, and the procedure is invasive for patients without ALN metastasis. Here, we developed a diagnostic model for evaluating ALN status using a combination of serum miRNAs and clinicopathologic factors as a novel less-invasive biomarker.</p><p><b>Experimental Design:</b> Preoperative serum samples were collected from patients who underwent surgery for primary breast cancer or breast benign diseases between 2008 and 2014. A total of 958 serum samples (921 cases of primary breast cancer, including 630 cases in the no ALN metastasis group and 291 cases in the ALN metastasis group, and 37 patients with benign breast diseases) were analyzed by miRNA microarray. Samples were randomly divided into training and test sets. Logistic LASSO regression analysis was used to construct diagnostic models in the training set, which were validated in the test set.</p>Results:<p>An optimal diagnostic model was identified using a combination of two miRNAs (miR-629-3p and miR-4710) and three clinicopathologic factors (T stage, lymphovascular invasion, and ultrasound findings), which showed a sensitivity of 0.88 (0.84–0.92), a specificity of 0.69 (0.61–0.76), an accuracy of 0.818, and an area under the receiver operating characteristic curve of 0.86 in the test set.</p>Conclusions:<p>Serum miRNA profiles may be useful for the diagnosis of ALN metastasis before surgery in a less-invasive manner than SLNB.</p></div>
Patients with cervical adenocarcinoma (AC) and adenosquamous carcinoma (ASC) have a poorer prognosis than those with squamous cell carcinoma (SCC). Erb-b2 receptor tyrosine kinase 3 (HER3) is a member of the epidermal growth factor receptor family and its expression is associated with unfavorable prognosis in several cancer types, including SCC of the cervix. As there is limited information on the prognostic value of HER3 for AC and ASC of the cervix, the present study aimed to evaluate the expression of HER3 and its impact on post-operative recurrence in patients with AC and ASC of the cervix. This retrospective study included 39 patients with early-stage AC and ASC who underwent primary surgery between January 1997 and December 2017. Immunohistochemical staining for HER3 was performed on formalin-fixed paraffin-embedded surgical specimens. The possible influence of HER3 expression on disease-free survival (DFS) was studied by using multivariate Cox regression with adjustment for established risk factors of post-operative recurrence. High expression of HER3 (HER3-high) was detected in 85.1% of cases of AC (23/27) and in 58.3% of cases of ASC (7/12). The median follow-up duration was 63.1 months and Kaplan-Meier analysis indicated that the 5-year DFS rates of patients with AC and ASC of the cervix were 56.7% in patients with HER3-high and 77.8% in patients with HER3-low (log rank, P=0.20). On multivariate analysis, HER3-high [hazard ratio (HR)=6.32, 95% CI: 1.10-36.26, P=0.039), pelvic lymph node metastasis (HR=7.61, 95% CI: 2.07-28.00, P=0.002) and vascular invasion (HR=4.28, 95% CI: 1.12-16.31, P=0.033) were indicated to be independent predictors of DFS. To date, the present study is the most comprehensive analysis to evaluate the expression of HER3 in patients with early-stage AC and ASC of the cervix. The results suggested that HER3 overexpression may be an independent risk factor for post-operative recurrence. However, these results and the prognostic value of HER3 should be confirmed in a larger sample.
Recently, the anti-programmed cell death protein 1 antibody pembrolizumab, a type of immune checkpoint inhibitor (ICI), has been used in preoperative systemic chemotherapy for hormone receptor and human epidermal growth factor 2-negative breast cancer, also known as triple-negative breast cancer (TNBC). Chemotherapy with pembrolizumab has demonstrated clinical activity in terms of pathologic complete response and event-free survival. Despite their efficacy, the current understanding of the full spectrum of side effects associated with relatively new ICIs remains incomplete. The present study describes a case of severe pembrolizumab-induced hemophagocytic lymphohistiocytosis in a patient with early-stage TNBC, and the strategies used to manage the patient in light of their pathophysiology.
629 Background: Hepatitis C virus (HCV) infection is one of the most common blood-borne infection in the world, and with an estimated to be infected more than 880,000 people in Japan. Little is known about the changes of HCV status during chemotherapy and the influence of HCV infection on toxicity of chemotherapy. Methods: We reviewed all patients diagnosed with colorectal cancer in our institution between 2001 and 2012 who had been screened for HCV infection by testing for anti-HCV antibody and identified 77 HCV-infected patients. We retrospectively analyzed the change in HCV load and the toxicities of chemotherapy in these patients. Results: Twenty-four of the 77 HCV-infected patients with colorectal cancer had received chemotherapy.The median age was 66 years (range: 42-80 years). Four patients had liver cirrhosis at the initiation of chemotherapy. The remaining 20 patients were diagnosed with chronic hepatitis, and their liver function tests and complete blood cell counts at baseline were normal. First-line chemotherapy included 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) (n = 6), S-1 and irinotecan (IRIS) (n = 1), tegafur-uracil (n = 14), capecitabine (n = 1), capecitabine and oxaliplatin (XELOX) (n = 2).Serum HCV-RNA levels both before and after chemotherapy were evaluated in 10 patients, and the median serum HCV-RNA level before and after chemotherapy was 4.0 and 3.05 logIU/ml, respectively. Transaminase levels were elevated during chemotherapy in 2 patients. There were no patients suffered from grade 3-4 neutropenia or febrile neutropenia. Conclusions: This study indicates that chemotherapy can be safely performed in HCV-infected patients with colorectal cancer without change in HCV load.
