Carmine is an aluminium and/or calcium-chelated complex form of carminic acid (CA), which is derived from the extract (cochineal), and is globally used as a red-colourant in foods and cosmetics. Although several allergens in carmine allergies, such as CC38K, have been reported, it remains unknown whether chelation affects the allergenicity of carmine. We report a case of Japanese fish sausage () anaphylaxis induced by epicutaneous sensitization to carmine contained in eyeshadows.

Article Synopsis
  • The BRAF V600E mutation is a resistance mechanism to EGFR-TKIs, highlighted by a case of a 54-year-old Japanese woman with lung adenocarcinoma who developed metastases post-surgery.
  • Despite initial treatment with osimertinib for an EGFR exon 19 deletion, a tumor nodule increased in size after several years of treatment.
  • A switch to dabrafenib and trametinib led to further growth of metastases, suggesting a need for repeated biopsies to understand new gene expressions and the potential benefit of combining treatments rather than switching.

Background: Atezolizumab, one of the immune checkpoint inhibitors, has been approved as an adjuvant treatment following resection and platinum-based chemotherapy in patients with stage II-IIIA non-small cell lung cancer with 1% or more programmed death ligand-1 (PD-L1) expression. The Food and Drug Administration (FDA) has approved SP263 as a companion diagnostic assay for adjuvant treatment with atezolizumab; however, in clinical practice, the 22C3 assay is most commonly used for advanced non-small cell lung cancer. Therefore, our study aimed to compare two PD-L1 assays, SP263 and 22C3, to evaluate whether 22C3 could replace SP263 when deciding whether to administer adjuvant atezolizumab.

Background: The recurrence site that influences post-recurrence survival (PRS) in patients with non-small cell lung cancer (NSCLC) undergoing surgery and the preoperative predictors of recurrence remain unclear.

Methods: Cohorts 1 and 2 had 4520 (who underwent complete resection for p-stage 0-IIIA NSCLC) and 727 (who experienced recurrence after surgery) patients, respectively. The initial sites of recurrence were the lungs (309 cases), thoracic lymph nodes (225 cases), pleura (112 cases), bone (110 cases), central nervous system (86 cases), adrenal gland (25 cases), abdomen (60 cases), cervical and axillary lymph nodes (38 cases), chest wall (13 cases), skin (5 cases), and eye and tongue (3 cases).

Article Synopsis
  • Segmentectomy is a less invasive surgical option compared to lobectomy for patients with non-small cell lung cancer (NSCLC), but the reasons behind this reduced invasiveness are not well understood.
  • The study analyzed data from 315 patients who had either segmentectomy or lobectomy, measuring changes in psoas muscle mass over postoperative periods using CT scans.
  • Results showed that the lobectomy group experienced significantly greater muscle mass loss compared to the segmentectomy group, with muscle mass remaining stable in the segmentectomy group throughout the observation period.

Background: Dried blood spots (DBSs) are promising candidates for therapeutic drug monitoring. In this study, a simple method for the simultaneous measurement of tyrosine kinase inhibitors (TKIs), including bosutinib, dasatinib, ibrutinib, imatinib, nilotinib, and ponatinib, using DBS was developed and validated. The prediction of the plasma concentration of TKIs based on the TKI concentrations in the DBS was assessed using the developed measurement method.

Background: There are few reports on the utility of the maximum standardized uptake value (SUVmax) for predicting the prognosis of early-stage lung adenocarcinoma based on the latest tumor-node-metastasis (TNM) classification. This study aimed to determine whether clinicopathologic factors, including the SUVmax, affect prognosis in these patients.

Patients And Methods: We enrolled 527 patients with c-stage IA lung adenocarcinoma who underwent lobectomy or greater resection between 2011 and 2017.
