The concurrent onset of chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML) is rare, and no autopsy case has been reported. We report herein the first case of concurrent-onset CLL and AML with an atypical phenotype revealed by autopsy. Notably, the diagnosis of AML was quite difficult during the patient's lifetime because of the atypical phenotype. However, autopsy revealed that the patient's bone marrow, liver, and spleen were filled with myeloblasts. In addition, p53 stain and PCR of IgH rearrangement using the autopsy specimen suggested that CLL and AML might be different clones. In conclusion, our case highlights the importance of considering synchronous complications of AML in CLL patients, particularly in those with an atypical clinical course.Breast cancer metastasis to the gastrointestinal tract is relatively rare. Patients with such disease often develop gastrointestinal symptoms, but it is sometimes asymptomatic. Endoscopic findings of gastric metastasis from breast cancer markedly vary from benign to malignant, and even in suspected malignant cases, it is often difficult to differentiate between primary and metastatic disease. We experienced a case in which an endoscopic examination performed during the treatment for metastatic breast cancer resembled an early-stage gastric cancer. A 71-year-old woman underwent curative surgery for right breast cancer 16 years previously. She underwent endoscopic submucosal dissection for early-stage gastric cancer 5 years ago. Two years ago, she developed metastatic disease in the lungs and mediastinal lymph nodes, and endocrine therapy was administered. At the same time, a follow-up endoscopy revealed a new elevated lesion, suspected to be an early-stage gastric cancer. However, histological diagnosis of the biopsy was metastasis of breast cancer. One and a half years later, a follow-up endoscopy revealed a gastric lesion that had reduced in size. She is still alive, having received a variety of systemic treatments. Patients with metastatic breast cancer are experiencing prolonged survival. Thus, follow-up endoscopy should be considered after the diagnosis of gastrointestinal metastasis considering the risk of lethal conditions, such as gastrointestinal bleeding and perforation. Our case serves as a reminder to clinicians how difficult it is to determine whether a gastric lesion is primary or metastatic based on endoscopic findings and the importance of communication with endoscopists and pathologists.A 69-year-old man with refractory lung adenocarcinoma was treated with gemcitabine and vinorelbine. Dyspnea and hypertension developed after the 17th cycle of chemotherapy. Laboratory findings revealed intravascular hemolysis and renal dysfunction. Thrombotic microangiopathy (TMA) was confirmed by renal biopsy. Antihypertensive and steroid therapies were ineffective. After plasmapheresis, intravascular hemolysis and renal dysfunction gradually improved. However, the disease progressed, and he died 6 months after TMA diagnosis. Autopsy revealed similar pathological findings to those of the renal biopsy. It is important to discontinue gemcitabine at the onset of TMA and consider TMA when using gemcitabine for long periods.Quantitative PCR-based strategies are typically effective for monitoring BCR-ABL1 transcript levels in chronic myeloid leukemia (CML). Additionally, some patients treated with tyrosine kinase inhibitors can experience long-term treatment-free remission after discontinuation of the inhibitor. However, this outcome hinges on effectively monitoring the patient's response to therapy. We present a patient with CML and multiple BCR-ABL1 transcripts, including a rare isoform that lacks qPCR standardization. We describe unexpected discrepancies in transcript quantification, further having an impact on clinical decision-making regarding duration of treatment. To better inform clinical practice, we suggest monitoring patients at the same testing facility to better track transcript trend.Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the thyroid germinal centers. To the best of our knowledge, there are only 4 reported cases of thyroid FDCS in the English literature. Herein, we present the fifth case of FDCS of the thyroid gland. A 63-year-old woman presented with a painless midline neck mass, enlarging for the last 4 months. Physical examination revealed a 6-cm nonmobile, firm, multinodular thyroid mass with palpable cervical lymphadenopathy. Due to high suspicion for thyroid malignancy, the patient underwent total thyroidectomy with bilateral modified radical neck dissection. Histologic evaluations revealed sheets of storiform eosinophilic tumoral cells with prominent nucleoli containing multinucleated giant cells, and subsequent immunohistochemistry showed immunoreactivity for CD4, CD21, CD35, CD45 (LCA), and CD68. The patient was started on 6 cycles of doxorubicin, ifosfamide, and radiotherapy. She has had monthly thyroid ultrasonography and contrast-enhanced thoracoabdominal CT scan every 3 months for detecting potential recurrence and/or metastasis screening. Fortunately, 8 months after the operation, the patient is alive without any signs of local or distant metastasis.Retroperitoneal sarcomas are rare entities. They have a tendency of growing slowly, rendering the patient apparently healthy for long periods of time, before diagnosis. Besides, they have a worse prognosis than sarcomas arising in extremities, with a higher local recurrence rate and lower 5-year survival rate. We describe a case of a 71-year-old male patient, who had a very well succeeded treatment of a large retroperitoneal sarcoma with the combination of chemoembolization, systemic chemotherapy, surgery, and radiation therapy. Initially, it was noticed in an incidental way he had a large retroperitoneal mass (15 cm × 10 cm × 9.2 cm) through magnetic resonance, when he was 63. The case was considered inoperable by the treating physicians. After neoadjuvant therapy, the residual tumor could be completely excised by the responsible surgeon. With a follow-up of >5 years, since the end of treatment, the patient remains in complete remission and, probably, cured from his illness. Large retroperitoneal sarcomas are still a great challenge for oncologists. According to the medical literature, chemoembolization can benefit some patients, but most of them in a palliative setting. In our report, we believe its contribution was critical for a great outcome. In selected cases, it is possible this procedure may be an additional therapeutic modality, as part of a multidisciplinary approach.Gastric cancer is one of the most common and deadly cancers worldwide. Screening tests as well as tools for prediction of treatment outcomes and prognosis have been developed, but they have many limitations. The integration of liquid biopsy provided new aspects in screening and diagnosis of gastric cancer. In the present study, we used different techniques, studying the genetic and epigenetic profile of circulating tumor cells. We aimed to acquire all the available information, compare it with already existing studies, and evaluate the benefit of this approach. A blood sample was isolated from 2 gastric cancer patients at stages III-IV, followed by the isolation of CTCs. Lorlatinib The circulating tumor cells were used for array comparative genomic hybridization, next-generation sequencing, and whole gene expression microarrays. Different variants were detected, while the microsatellite instability status was stable in both cases. The tumor mutational burden was low to medium. Gene expression assays revealed that >100 genes were overexpressed compared to noncancer samples. Amplifications of X chromosome were also observed in both cases, by using array comparative genomic hybridization. Although there are several techniques for cancer screening, prediction of therapy outcomes, and prognosis, the application of a complete comprehensive cancer panel, combining the study of variants, fusions, chromosomal abnormalities, and gene expression, is more appropriate. Information provided by the above techniques might contribute in designing more efficient treatment protocols and screening tools. Despite the limitation of samples, the data are encouraging, and further study is needed so that they can be used at clinical level.Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of nonsmall-cell lung cancer (NSCLC). It carries a poor prognosis, even among other subtypes of NSCLC. Currently, most treatment strategies for PSC are derived from regimens aimed at managing soft tissue sarcomas or NSCLC. The use of doxorubicin plus ifosfamide and pemetrexed has been well established in the management of soft tissue carcinoma and other nonsmall-cell lung cancers, respectively. We report the case of a 69-year-old male diagnosed with PSC who was managed with doxorubicin plus ifosfamide and pemetrexed therapy. Our patient initially responded to the therapy but had rapid progression and died 8 months after the initiation of treatment. Upon genetic analysis, it was revealed the patient had overexpression of the MDM2 protein, which has been associated with poor response to therapy. This case highlights the need for a personalized treatment approach, as well as the need for a standardized treatment regimen for managing PSC.Drug-induced interstitial lung disease (DILD) has been occasionally reported with various causative drugs. In the context of breast cancer, anthracycline infrequently causes pulmonary adverse events. We report a 67-year-old woman with cT2N0M0 triple-negative breast cancer who received neoadjuvant chemotherapy with anthracycline-combined chemotherapy with pegfilgrastim. She developed fever, cough, and shortness of breath after 21 days of the scheduled fourth cycle of anthracycline. Computed tomography revealed drug-induced interstitial pneumonia. Prednisolone (1 mg/kg) was administrated and gradually decreased. Thereby, interstitial pneumonia quickly improved. Partial resection of the left breast and sentinel lymph node biopsy were performed, and we diagnosed ypT1bN0. The patient received 4 cycles of taxane and hypofractional radiotherapy and survived without any recurrences over the following 37 months. We report a rare case of DILD due to anthracycline-combined chemotherapy. Twenty-five cases of DILD with breast cancer after administration of anthracycline have been reported so far. However, 14 cases occurred during taxane. Most of the cases had remission by steroid treatment. The patients with respiratory symptoms during chemotherapy should be suspicious of not only infection but also DILD.Cardiological patients with malignant tumors belong to a complex category of patients. We present the world's first case of simultaneous surgical treatment of severe mitral valve disease and esophageal cancer. The patient underwent simultaneous replacement of the mitral valve and the Ivor-Lewis procedure using right thoracotomy and upper midline laparotomy. The patient underwent 3 courses of chemotherapy (paclitaxel and 5-fluoroucil). Follow-up for 8 months showed no signs of tumor recurrence or cardiac problems. A dextral thoracotomy with the lung deprivation, supplemented by an upper median laparotomy, achieved us convenient access to the mitral valve and to all parts of the esophagus, including groups of compromised lymph nodes. This case demonstrates the modern possibilities of simultaneous cardio and oncosurgery that allows eliminating competitive fatal diseases in 1 surgical and anesthetic intervention.
