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. Thus, we aimed to examine whether these factors could also be prognostic markers for chemoimmunotherapy. We retrospectively examined 237 patients with advanced NSCLC treated with chemoimmunotherapy. In the total group, the median overall survival (OS) was not reached, and the median progression-free survival (PFS) was 8.6 months. Multivariate analysis of OS and PFS revealed significant differences based on PNI and LIPI. Programmed cell death ligand 1 (PD-L1) was also significantly associated with OS and PFS. PNI and a PD-L1 tumor proportion score (TPS) of <50% and poor LIPI (regardless of PD-L1 TPS) were associated with poor prognosis. PNI and LIPI predicted survival outcomes in patients with advanced NSCLC treated with chemoimmunotherapy, especially in patients with PD-L1 TPS <50%. For patients in this poor category, chemoimmunotherapy may result in a worse prognosis than expected.
Background: First-line chemoimmunotherapy (CIT) has improved overall survival (OS) and progression-free survival (PFS) outcomes among patients with non-small cell lung cancer (NSCLC). The immunological and nutritional statuses of patients fluctuate during treatment using immune checkpoint inhibitors, and are closely related to treatment outcomes. However, it is unclear whether these markers are significant in patients who are receiving CIT. Methods: This retrospective single-center study evaluated 34 consecutive Japanese patients with NSCLC who were treated using first-line CIT. Previously reported markers that reflect immunological and nutritional statuses were evaluated at three time points: at the start of CIT, after three weeks, and at the end of induction therapy. Results: The median PFS was 7.2 months (95% confidence interval: 6.3 monthsnot reached) and the median OS was not reached (95% confidence interval: 9.6 months-not reached). The PFS duration was significantly associated with the baseline neutrophil-to-lymphocyte ratio and the three-week values for the modified Glasgow prognostic score, C-reactive protein-albumin ratio, prognostic nutrition index, and advanced lung cancer inflammation index. The OS duration was significantly associated with the pre-treatment values for the neutrophil-tolymphocyte ratio and advanced lung cancer inflammation index, as well as the prognostic nutrition index at the end of induction therapy. Conclusions: Immunological and nutritional markers could be useful for predicting the outcomes of CIT for Japanese patients with advanced non-small cell lung cancer. The timing of their evaluation may also be important.
The efficacy of nintedanib treatment in patients with idiopathic pulmonary fibrosis (IPF) was demonstrated in phase III trials. However, there is limited data on the significance of nintedanib in elderly patients aged ≥75 years. We have retrospectively evaluated 54 newly nintedanib-treated patients including 32 elderly individuals. Potential changes in modified medical research council (mMRC) grade and COPD (chronic obstructive pulmonary disease) assessment test (CAT) score, as well as in forced vital capacity (FVC) were obtained 6 months before, at the time of, and 6 and 12 months after initiation of nintedanib treatment. Significant differences were observed in CAT scores between 6 months before treatment and baseline (p < 0.001), and between baseline and 6 months (p < 0.001) and 12 months (p < 0.001) after treatment. If subjective improvement is defined as an improvement in mMRC grade or CAT score by 1 or 3 points, respectively, 25 patients (46.3%) have significantly improved after 6 months of treatment. Out of these, all have improved in CAT score. The tolerability of nintedanib was similar in elderly and younger patients. These findings suggest that CAT scores could be useful in the subjective assessment during nintedanib treatment, and that nintedanib is safe and efficient for the treatment of the elderly population.
Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are life-threatening dermatologic adverse events in the same category, caused by a delayed-type drug hypersensitivity reaction. Although skin toxicity is common during treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), osimertinib-associated TEN is quite rare—thus far, only one report has been published from China. We report a case of an 80-year-old Japanese woman with lung adenocarcinoma harboring an EGFR-sensitizing mutation who was treated with osimertinib as the first-line treatment. Forty-six days after osimertinib induction, diffuse erythematous rash rapidly spread over the patient’s trunk along with vesicles and purpuric macules; furthermore, she developed targetoid erythema on the face. Despite osimertinib discontinuation and corticosteroid treatment, diffuse erythema with Nikolsky’s sign, general epidermal detachment, erosion and loose blisters developed over her entire body including the face. Based on her symptoms, TEN was diagnosed and thus, intravenous immunoglobulin was immediately administered for 4 days. The treatment ameliorated TEN-associated skin toxicity and caused epithelialization. Reports on osimertinib-associated SJS/TEN are scarce and only one report each on SJS and TEN from China is available. This is the first report of osimertinib-associated TEN from Japan. Cases of EGFR-TKI-associated SJS/TEN have been reported predominantly from Asian countries, suggesting ethnicity and genetic linkage play a role in the underlying mechanism.
Vogt–Koyanagi–Harada disease (VKHD) is a rare systemic granulomatous autoimmune disease that affects melanocyte‐rich organs such as eye, inner ear, meninges, skin, and hair. VKHD leads to chronic uveal inflammation accompanied by a decline in visual acuity in some patients when appropriate corticosteroid treatment was not initiated in an early phase. Immune checkpoint inhibitors (ICIs) are widely used in the treatment of several kinds of cancers and chemoimmunotherapy has become the standard of care in the first‐line treatment of non‐small cell lung cancer (NSCLC). While ICIs induce immune‐related adverse events, drug‐induced VKHD is quite rare with only four reports in the ICI monotherapy; three patients with melanoma and one patient with NSCLC. We describe the first case of VKHD during chemoimmunotherapy including pembrolizumab in a patient with NSCLC, which was successfully treated with corticosteroid without any sequela.
A 69‐year‐old woman was diagnosed with a breakpoint cluster region‐Abelson‐positive chronic myeloid leukaemia and treated with dasatinib for 14 months. She presented with one month of high‐grade fever and persistent dry cough. Chest computed tomography revealed non‐segmental subpleural consolidation, ground‐glass opacities, and interlobular septal thickening. The bronchoalveolar lavage (BAL) and transbronchial lung biopsy confirmed a diagnosis of drug‐induced interstitial lung disease (ILD) associated with dasatinib. Then, systemic corticosteroid treatment was initiated, which was effective and the interstitial shadow disappeared after two weeks. The acid‐fast bacilli culture test of BAL fluid after three weeks was positive for Mycobacterium tuberculosis, and combination therapy with four antituberculosis drugs was added. It is known that drug‐induced ILD and susceptibility to infection associated with dasatinib occur in a dose‐dependent manner. This is the first case of dasatinib‐induced ILD which coincided with active tuberculosis.
Atezolizumab was the first immune checkpoint inhibitor (ICI) to be introduced as a first‐line treatment option for extensive‐stage small cell lung cancer (ES‐SCLC), in combination with carboplatin and etoposide (CE) chemotherapy. However, SCLC treatment options after progression to first‐line chemotherapy are limited, warranting the readministration of previously used drugs. In combination with atezolizumab, CE readministration may theoretically be effective, based on two tentative mechanisms: its additive and synergistic effects on cytotoxic chemotherapy. The additive effect is based on the IFCT‐1603 trial in which the Kaplan‐Meier estimates of both progression‐free survival (PFS) and overall survival (OS) in the atezolizumab group exhibited a tail plateau in the selected population. Conversely, an anti‐PD‐L1 antibody synergistic effect on platinum compounds was assessed in a preclinical study, which was reinforced by clinical data. Thus, atezolizumab in combination with CE may be a treatment option in heavily treated patients. Here, we describe the first case of a heavily treated ES‐SCLC patient treated with chemoimmunotherapy, resulting in a partial response and a durable PFS. Key points Significant findings of the study and what this study adds CE readministration with atezolizumab may be effective based on two tentative mechanisms. Additive and synergistic effects of atezolizumab on CE have been previously suggested via a clinical trial and preclinical study, respectively. This is reflected in the current case in clinical settings.
Background: The management of severe asthma-associated symptoms is essential since they are distressing to the affected patients, and also greatly impair their quality of life. Dupilumab, a monoclonal antibody, blocks interleukin (IL)-4 and IL-13 signaling, both of which are crucial in acquired and innate immunity pathways through fast signal transduction, leading to an early response to treatment. Although rapid improvement within 1–3 days after dupilumab treatment was observed in moderate-to-severe atopic dermatitis, an early response within 7 days of dupilumab treatment in severe asthma has not been reported. Methods: Twelve consecutive patients with severe asthma who were newly treated with dupilumab between July 2019 and April 2020 were retrospectively investigated. We evaluated the early response (within 7 days) of patients with severe asthma receiving dupilumab therapy. Asthma control test (ACT) and the daily ACT, which was modified from the ACT to evaluate daily symptoms associated with asthma, were adopted as patient-reported outcomes (PROs) at week 8 and within 7 days, respectively. Patients were stratified into early responders (7 days), late responders (week 8), and non-responders without significant improvement in PROs. Descriptive statistics were adopted due to the limited number of patients.Results: Four of these 12 patients were early responders, with the following baseline characteristics: body mass index, <25 kg/m2; without depression; baseline forced expiratory volume in 1 second, <1.50 L; and more than one exacerbation in 1 year. On the other hand, five were late responders, and 44.4% of the nine responders were early responders. The higher the eosinophilic count and/or FeNO did not show any relationship between the early responder and nonresponder.Conclusions: The effect of dupilumab on severe asthma in patients with atopic features could be started earlier than 2 weeks, similar to atopic dermatitis. Daily ACT may be useful in monitoring the early efficacy of dupilumab in treating severe asthma.
