Tumor Pseudoprogression

S Foller, H Oppel-Heuchel, M-O Grimm
In contrast to chemotherapy, treatment with immune checkpoint inhibitors occasionally results in an unconventional pattern of response. Besides an early partial or complete response or tumor progression, a so-called pseudoprogression, a "mixed response" or late responses can also be observed. Treatment beyond radiographically defined progression may therefore be appropriate in selected cases. For these treatment decisions, the clinical evaluation of the patient (performance status, symptoms, etc...

Nivolumab is an anti-PD-1 blocking monoclonal antibody approved for the treatment of non-small cell lung cancer (NSCLC). However, some patients on immunotherapy may experience rapid progression and worsening clinical status, known as hyperprogressive disease. We retrospectively reviewed the clinical records of patients with NSCLC administered nivolumab therapy at Toneyama National Hospital, Japan, from January 2016 to January 2018. Of the 87 patients administered nivolumab therapy, five experienced rapid progression during one cycle of nivolumab therapy...

Although programmed death (PD)-1 immune checkpoint therapies target the immune system, the relationship between inflammatory factors and the clinical outcome of anti-PD-1 therapy for non-small cell lung cancer (NSCLC) is not fully understood. Here we examined the association between soluble immune mediators and the outcome of treatment with PD-1 inhibitors in patients with advanced/recurrent NSCLC. In two independent cohorts, we assessed the levels of 88 different soluble immune mediators in peripheral blood before and after anti-PD-1 treatment, and evaluated their associations with clinical outcomes...

Background: Central nervous system (CNS) tumors are a rare but devastating malignancy, often robbing patients of the basic quality of life. Despite advances in our understanding of the CNS tumor disease processes, the prognosis for patients with CNS tumors remains poor. Better characterization and diagnostic and monitoring approaches are necessary to assist in diagnosis and treatment of CNS tumors. One important tool in the neuro-oncology armamentarium is the use of advanced imaging techniques...

BACKGROUND: Chondrosarcoma is one of the most common malignant bone tumors in adults. Conventional chondrosarcoma represents around 85% of all chondrosarcomas and is notoriously difficult to treat with chemotherapy. CASE PRESENTATION: We describe a 67-year-old man with metastatic conventional chondrosarcoma who was treated with nivolumab. Treatment was discontinued after restaging showed increased tumor burden, which later proved to be pseudoprogression. The patient restarted nivolumab and continues to have a near complete response...

BACKGROUND: Immunotherapy is a new paradigm for the treatment of non-small-cell lung cancer (NSCLC), and targeting the PD-1 or PD-L1 pathway is a promising therapeutic option. Although PD-1/PD-L1 inhibitors are more effective than standard chemotherapy in lung cancer, clinicians are afraid to actively use them because of hyperprogression and pseudoprogression. The aim of this study was to investigate the factors associated with tumor response and serious outcomes. METHODS: We retrospectively collected the medical records of 51 patients with advanced NSCLC who received PD-1/PD-L1 inhibitors between January 2016 and February 2018...

Nivolumab, an anti-PD-1 antibody, has been shown to be effective in many cancers, such as malignant melanoma and lung cancer; however, nivolumab therapy can result in pseudoprogression. Diffuse alveolar hemorrhage (DAH) is persistent or recurrent pulmonary hemorrhage as a result of drugs, autoimmune diseases, or infections. DAH with pseudoprogression during nivolumab administration has rarely been reported. Herein, we describe our experience with one such case. A 41-year-old woman exhibited bloody sputum and ground glass opacities in the lungs along with tumor growth during nivolumab therapy for multiple lung metastases of malignant melanoma...

Immunotherapy is associated with different response patterns compared with chemotherapy and targeted therapy, including delayed response and stabilization after progression (pseudoprogression). According to new immuno-based response criteria, immunotherapy can be continued after radiological progression when a clinical benefit is observed. We report a case of an advanced renal cell carcinoma patient treated with nivolumab, who developed clinical benefit and delayed radiological response after initial progression...

Patterns of response and progression to immunotherapy may differ from those observed with drugs such as chemotherapy and molecularly targeted agents. Specifically, some patients experience a response after progression that is retrospectively named pseudoprogression. This phenomenon of pseudoprogression, first reported in patients with melanoma who were treated with ipilimumab, has led to the development of immune-specific related response criteria, such as irRC (immune-related response criteria), irRECIST (immune-related RECIST), and iRECIST (immunotherapy RECIST) that allow continued treatment beyond progression...

Radiologic predictors of response to immune checkpoint blockade (ICPi) in advanced head and neck squamous cell carcinoma (HNSCC) patients could help guide patient selection and management. We analyzed a large institutional cohort of 100 consecutive HNSCC patients treated with ICPi to investigate associations between molecular and radiologic phenotype and assess radiologic predictors of response and survival. Of particular interest was the impact of increased total tumor burden (TB), calculated as the sum of the largest diameter of all measurable lesions according to RECIST 1...

Assessing tumor response is a large part of everyday clinical work in neuroradiology. However in the setting of tumor treatment, distinguishing tumor progression from treatment-related changes is difficult on conventional MRI sequences. This is made even more challenging in children where mainstay advanced imaging techniques that are often used to decipher progression versus treatment-related changes have technical limitations. In this review, we highlight the challenges in pediatric neuro-oncologic tumor assessment with discussion of pseudophenomenon including pseudoresponse and pseudoprogression...

Importance: Hyperprogressive disease (HPD) is a new pattern of progression recently described in patients with cancer treated with programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) inhibitors. The rate and outcome of HPD in advanced non-small cell lung cancer (NSCLC) are unknown. Objectives: To investigate whether HPD is observed in patients with advanced NSCLC treated with PD-1/PD-L1 inhibitors compared with single-agent chemotherapy and whether there is an association between treatment and HPD...

Background: Pseudoprogression is a diagnostic challenge in early post-treatment glioblastoma. We therefore developed and validated a radiomics model using multiparametric MRI to differentiate pseudoprogression from early tumor progression in patients with glioblastoma. Methods: The model was developed from the enlarging contrast-enhancing portions of 61 glioblastomas within 3 months after standard treatment with 6472 radiomic features being obtained from contrast-enhanced T1-weighted imaging, fluid-attenuated inversion recovery imaging, and apparent diffusion coefficient (ADC), and cerebral blood volume (CBV) maps...

PURPOSE: For glioblastoma (GBM), imaging response (IR) or pseudoprogression (PSP) is frequently observed after chemoradiation and may connote a favorable prognosis. With tumors categorized by the Cancer Genome Atlas Project (mesenchymal, classical, neural, and proneural) and by methylguanine-methyltransferase (MGMT) methylation status, we attempted to determine if certain genomic or molecular subtypes of GBM were specifically associated with IR or PSP. METHODS: Patients with GBM treated at two institutions were reviewed...

Cancer research is living a time of unparalleled expectations around immunotherapy, a therapeutic strategy that materializes the elegant idea of weaponizing our immune system to eradicate tumor cells. In an everchanging standard of care, a growing number of studies have shown that immunotherapy may accelerate tumor progression in a significant subset of patients ranging from 4% to 29% across multiple histologies. The identification of hyperprogression poses a challenge for RECIST criteria, which fail to capture pre- and post-treatment tumor growth kinetics at early times of disease...

Immune checkpoint inhibitors are increasingly used in treatment of metastatic renal cell carcinoma, melanoma, and nonsmall cell lung cancer, as well as in clinical trials for novel targets. We present a pediatric patient with metastatic alveolar soft part sarcoma who was treated with MPDL3280 (Atezolizumab), a monoclonal anti-programmed death ligand-1 antibody. Imaging results for the patient suggested disease progression of multiple brain metastases with stable systemic disease. The patient met response evaluation criteria in solid tumors (RECIST) criteria of progression of disease and was removed from treatment with MPDL3280...

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. Serum tumor marker might help to distinguish pseudoprogression.

Immunotherapies comprise of a class of cancer therapies that are increasingly used for treatment of several cancer entities. Active immunotherapies encompassing immune checkpoint inhibitors are the most widespread class of immunotherapies, with indications for melanoma, non-small lung cancer, renal cell carcinoma, urothelial carcinoma, head and neck squamous cell carcinoma, and Hodgkin's lymphoma. Immune checkpoint inhibitors have demonstrated unique response patterns that are not adequately captured by traditional response criteria such das the Response Evaluation Criteria in Solid Tumors (RECIST) and World Health Organization criteria...

Squamous cancer (SqCC) of the lung has a poor prognosis. With the advent of immunotherapy, prognosis has tended to improve; however, pseudoprogression poses a challenge to the management of immunotherapy. Herein, we discuss the case of a 47-year-old heavy smoker with advanced SqCC. The patient had recurrent disease after initial successful control of the tumor by concurrent radiochemotherapy, together with ample pleural effusion. Pleural effusion was well controlled with systematic nivolumab and intra-thoracic recombinant endostatin; however with simultaneous deterioration of performance and tumor progression...
