A case of pulmonary co-infection with and Mucorales in a patient with sarcoidosis.

A 54-year-old woman with fever and cough presented with left upper lobe consolidation and para-aortic and hilar lymphadenopathies and was diagnosed with sarcoidosis, and her condition improved spontaneously. Over the next 15 years, the patient experienced seven similar episodes and was treated with glucocorticoids for the first time in the eighth episode, but subsequently died of respiratory failure. The autopsy revealed diffuse alveolar damage and co-infection with and Mucorales in the lungs and mediastinum.

Cytokine Release Syndrome with Relative Adrenal Insufficiency Induced by Ipilimumab and Nivolumab Combination Therapy for Clear Cell Renal Cell Carcinoma.

Combination therapy with ipilimumab and nivolumab is indicated for many types of cancers; however, several patients experience immune-related adverse events (irAEs). We herein report a case of cytokine release syndrome (CRS) in a 63-year-old woman with stage IV left clear cell renal cell carcinoma. Our patient developed CRS while taking prednisolone, 43 days after the start of ipilimumab and nivolumab administration.

Ramucirumab Plus Docetaxel for Patients with Non-small cell Lung Cancer with Brain Metastases: A Multicenter, Open-Label Single-Arm Phase II Trial.

Background: Ramucirumab plus docetaxel combination therapy (DOC/RAM) for advanced non-small cell lung cancer (NSCLC) achieves favorable outcomes; however, efficacy and safety for patients with brain metastases are still unclear.

Methods: Eligible patients included those with advanced NSCLC with measurable asymptomatic brain metastases that progressed after chemotherapy. Patients were intravenously administered ramucirumab (10 mg/kg) and docetaxel (60 mg/m2) every 21-day cycle.

Prognostic Nutritional Index and Lung Immune Prognostic Index as Prognostic Predictors for Combination Therapies of Immune Checkpoint Inhibitors and Cytotoxic Anticancer Chemotherapy for Patients with Advanced Non-Small Cell Lung Cancer.

Combination therapy with immune checkpoint inhibitors and cytotoxic chemotherapies (chemoimmunotherapy) is associated with significantly better survival outcomes than cytotoxic chemotherapies alone in patients with advanced non-small cell lung cancer (NSCLC). However, there are no prognostic markers for chemoimmunotherapy. The prognostic nutritional index (PNI) and lung immune prognostic index (LIPI) are prognostic biomarkers for immune checkpoint inhibitor (ICI) monotherapy or cytotoxic chemotherapies.

Impact of maintenance therapy following induction immunochemotherapy for untreated advanced non-small cell lung cancer patients.

Purpose: The primary objective of this study was to identify the potential predictors to assess the impact of maintenance therapy after induction immunochemotherapy in the real-world setting of patients with advanced non-small cell lung cancer (NSCLC).

Methods: We retrospectively identified 152 patients with advanced NSCLC who received immunochemotherapy at 8 hospitals in Japan between January 2019 and December 2019. Patients who received at least four cycles of induction immunochemotherapy and one cycle of maintenance therapy with immune checkpoint inhibitors were included.

Early discontinuation of induction therapy in chemoimmunotherapy as an effective alternative to the standard regimen in patients with non-small cell lung cancer: a retrospective study.

Purpose: We aimed to investigate whether induction chemotherapy with less than four courses is as effective as induction chemotherapy with more than four courses in non-small cell lung cancer (NSCLC) patients receiving chemoimmunotherapy.

Methods: We retrospectively enrolled 249 patients with NSCLC who received chemoimmunotherapy at 12 centers in Japan between January and December 2019. The patient group that completed less than four courses owing to adverse events (AEs), and received subsequent maintenance therapy was compared to the group that received at least four courses of induction chemotherapy followed by maintenance therapy.

Clinical impact of pembrolizumab combined with chemotherapy in elderly patients with advanced non-small-cell lung cancer.

Objectives: Combination therapy of immune checkpoint inhibitors and chemotherapy is considered to be one of the standard treatment options for patients with advanced non-small-cell lung cancer (NSCLC). However, the clinical significance of immune checkpoint inhibitors combined with chemotherapy in elderly patients with NSCLC has not yet been fully understood. Therefore, this study aimed to evaluate how aging affects the therapeutic impact of chemotherapy combine with immune checkpoint inhibitors in elderly patients.

Impact of cancer cachexia on the therapeutic outcome of combined chemoimmunotherapy in patients with non-small cell lung cancer: a retrospective study.

Although previous studies suggest that cancer cachexia is a poor prognostic factor for immune checkpoint inhibitor monotherapy, the impact of cancer cachexia on chemoimmunotherapy is unclear. We investigated the impact of cancer cachexia on the therapeutic outcomes of chemoimmunotherapy for non-small cell lung cancer (NSCLC). We retrospectively analyzed patients' medical records with NSCLC who received chemoimmunotherapy in 12 institutions in Japan between January and November 2019.

Immune-Related Adverse Events Are Associated With Clinical Benefit in Patients With Non-Small-Cell Lung Cancer Treated With Immunotherapy Plus Chemotherapy: A Retrospective Study.

Background: The immunotherapy plus chemotherapy combination is one of the most promising treatments in advanced non-small-cell lung cancer (NSCLC). Immunotherapy often causes immune-related adverse events (irAEs), which have been reported to be associated with the good clinical outcomes. However, the effects of immunotherapy plus chemotherapy remain unknown.

Prolonged persistence of SARS-CoV-2 infection during A+AVD therapy for classical Hodgkin's lymphoma: A case report.

We describe a case of coronavirus disease 2019 (COVID-19) in a patient with mixed cellularity classical Hodgkin lymphoma (cHL) undergoing brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) therapy. A 43-year-old man presented to our hospital with a complaint of fever, for which he was diagnosed with COVID-19 after a positive polymerase chain reaction (PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and antiviral therapy with favipiravir and ciclesonide was started subsequently. The fever persisted for the first few days of treatment, but his respiratory status was stable, and he became asymptomatic and afebrile on day 9.

A case of non-small cell lung cancer with danazol-dependent aplastic anemia induced by pembrolizumab.

Programmed cell death protein 1 immune checkpoint inhibitor is an effective treatment for non-small cell lung cancer. Although hematological immune-related adverse events induced by antiprogrammed-cell-death-protein-1 immunotherapy have been reported, they are rare, and there remain many unknowns. We report the case of a 77-year-old woman with non-small cell lung cancer and pembrolizumab-induced danazol-dependent aplastic anemia.

Impact of preexisting antinuclear antibodies on combined immunotherapy and chemotherapy in advanced non-small cell lung cancer patients.

Combined immunotherapy and chemotherapy is a promising standard treatment in patients with advanced non-small cell lung cancer (NSCLC). This study aimed to evaluate the relationship between the combined therapy and pretreatment serum antinuclear antibody (ANA) levels as a prognostic indicator in patients with NSCLC. We retrospectively analyzed patients with advanced NSCLC who were treated with combinatorial immunotherapy and chemotherapy between January and December 2019 at six institutions in Japan.

High levels of anti-SSA/Ro antibodies in COVID-19 patients with severe respiratory failure: a case-based review : High levels of anti-SSA/Ro antibodies in COVID-19.

We treated two patients with severe respiratory failure due to coronavirus disease 2019 (COVID-19). Case 1 was a 73-year-old woman, and Case 2 was a 65-year-old-man. Neither of them had a history of autoimmune disease.

Carcinoembryonic antigen and CYFRA 21-1 responses as prognostic factors in advanced non-small cell lung cancer.

Background: It is unclear whether changes in serum tumor marker expression post-treatment are of prognostic value. We investigated the associations between changes in serum carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA 21-1) after first-line treatment and overall survival (OS) in non-small cell lung cancer (NSCLC).

Methods: Advanced NSCLC patients (April 2010 to December 2015) with elevated serum CEA or CYFRA 21-1 were included.

Prognostic impact of pleural effusion in EGFR-mutant non-small cell lung cancer patients without brain metastasis.

Background: In epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), brain metastasis is known as a poor prognosis factor. However, prognostic factors in the patients without brain metastasis remain unclear. In this study, we aimed to clarify the differences between metastatic site and prognosis in common EGFR-mutant NSCLC patients without brain metastasis.

An observational study of the epidermal growth factor receptor-tyrosine kinase inhibitor resistance mechanism in epidermal growth factor receptor gene mutation-positive non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutation show a high response to EGFR-tyrosine kinase inhibitor (EGFR-TKI). Clinically, EGFR-positive NSCLC acquires several resistance mechanisms during EGFR-TKI treatment, such as the emergence of a secondary mutation (T790M), MET gene amplification, and transformation to small cell lung cancer. However, the mechanism of resistance to afatinib, a second-generation EGFR-TKI, remains unclear.

Pulmonary pleomorphic carcinoma with pseudoprogression during nivolumab therapy and the usefulness of tumor markers: A case report.

Pseudoprogression was reported as one of the unconventional responses during immune checkpoint inhibitor therapy. A 70-year-old man with pulmonary pleomorphic carcinoma received nivolumab therapy. Pleural effusion and pulmonary metastasis increased, however then shrank and serum cytokeratin 19 fragment levels decreased.

Sarcoidosis complicated with major pulmonary artery obstruction and stenosis.

A 34-year-old woman with bilateral pulmonary infiltrates was diagnosed with sarcoidosis. She refused corticosteroid treatment despite a worsening of the pulmonary infiltrate, and thereafter developed dyspnea following hemoptysis 6 years later. The upper lobe branches of the pulmonary artery were obstructed and the left main pulmonary artery was narrowed by mediastinal soft tissue, thus complications of granulomatous mediastinitis and fibrosing mediastinitis were suspected.

[A case of Goodpasture's syndrome complicated with cytomegalovirus pneumonia during treatment with plasma exchange and immunosuppressive therapy].

A 63-year-old man presented to another hospital with hematuria and an elevated serum creatinine level. He was admitted, and hemodialysis was initiated. One month after admission, hemoptysis developed and the patient was referred to our hospital for further evaluation.

[Surgical management of eight cases of bronchiectasis].

Few reports are currently available on the surgical management of bronchiectasis. We report our experience with 8 cases of bronchiectasis. The indications of pulmonary resection were recurrent pneumonia and/or hemoptysis in spite of medical treatment and the extent mainly limited to the unilateral lung.

[Video assisted thoracic surgery for Mycobacterium avium complex pulmonary disease spread over multiple pulmonary lobe within one lung].

A 75-year-old woman with Mycobacterium avium complex (MAC) pulmonary disease who had been treated by drug therapy for 7 years was admitted on an emergency basis for hemoptysis. Through the previous 7 years, her sputum cultures had been positive for MAC, and her clinical symptoms and examinations, such as chest X-ray and computed tomography, revealed that her condition had worsened. The lesions spread over the right middle lobe, segment 3 (S3) in the right upper lobe, and segment 6 (S6) in the right lower lobe, however, no lesions were present in the left lung.

[Stromal bone formation by lung adenocarcinoma].

We report a case of lung adenocarcinoma with stromal bone formation. A 73-year-old woman was incidentally found to have a coin lesion in the left lower lung field on a chest roentgenogram and computed tomography showed a nodular lesion containing a few coarse high density areas in the left lower lobe. Since transbronchial cytology revealed adenocarcinoma, left lower lobectomy was performed.
