e18511 Background: Prior research has linked patient-physician sex discordance with inferior surgical and cardiac outcomes. The impact of such sex inequities may be magnified in medical oncology, where patients often face a life-limiting illness and physicians assume the role of primary healthcare provider. This study examined cancer treatment practices and survival outcomes in sex-concordant vs. discordant patient-physician dyads. Methods: This was a population-based, retrospective cohort study of adults diagnosed with stage II-IV colon or lung cancer in 2013-2020 in Alberta, Canada and referred to a medical oncologist. Study data included physician- and patient-level demographics and cancer disease characteristics. Patient-physician dyads were classified as sex-concordant (female-female, male-male) or discordant (female-male, male-female). Time-to-event data were analysed using Kaplan-Meier methods and associations were assessed with Cox and logistic regression. Results: A total of 11,131 patients and 188 medical oncologists were included. Among patients, 49% were female and 50% were in sex-concordant patient-physician dyads. The median age was 68 years, 7615 (68%) had lung cancer, and 6016 (54%) had stage IV disease. In sex-concordant and discordant dyads, respectively, median overall survival (OS) was 17.1 and 18.7 months ( p = 0.047) while median cancer-specific survival (CSS) was 20.2 and 22.4 months ( p = 0.21). In multivariable analysis, sex-concordance was not significantly associated with OS or CSS in the overall cohort and in female patients. However, among male patients, sex-discordance was significantly associated with lower OS (hazard ratio [HR], 1.11; 95% CI, 1.04-1.19) and CSS (HR, 1.12; 95% CI 1.04 -1.21), largely driven by differences in survival outcomes in stage IV disease. Older age, higher comorbidity burden, lung cancer, and advanced stage correlated with worse outcomes in all multivariable models. Sex concordance was not significantly associated with adjuvant systemic anti-cancer therapy (SACT) use in stage II-III disease or with SACT use in stage IV disease. Treatment practices are summarized in the table. Conclusions: Sex concordance between patients and medical oncologists did not generally correlate with differential SACT use and survival. However, male patients treated by female physicians had worse outcomes compared to those treated by male physicians. Cancer outcomes may be prone to the effects of sex bias in specific patient-physician relationships. [Table: see text]
Background: Oesophageal submucosal hematoma is a rare perioperative complication. When this complication develops after endovascular surgery, which requires postoperative antiplatelet therapy, whether to stop antiplatelet therapy or not is controversial. If antiplatelet therapy is discontinued, the appropriate time to resume antiplatelet therapy is unclear. Case presentation: A 75-year-old woman (height 134 cm, weight 37 kg) underwent flow diverter embolization for unruptured cerebral aneurysm under general anaesthesia. The patient received dual antiplatelet therapy before surgery and anticoagulation therapy intraoperatively. After surgery, the patient developed hematemesis and was diagnosed with oesophageal submucosal hematoma. Conservative treatment was initiated after discontinuing antiplatelet therapy, which was resumed 3 days after surgery. The patient showed good recovery even after the resumption of antiplatelet therapy. Conclusions: In our case, we successfully treated oesophageal submucosal hematoma developing after endovascular surgery with early resumption of postoperative antiplatelet therapy.
Background The preoperative diagnosis of pulmonary sclerosing pneumocytoma (PSP) is complicated since PSP has several histological structural patterns in the same neoplasm; hence, it is sometimes pathologically misdiagnosed as adenocarcinoma or carcinoid. In recent years, with the prevalence of transbronchial cryobiopsy (TBLC), we are able to obtain larger specimens than previously. However, to date, there have been no reports describing PSP diagnosed using TBLC. Case reports A 43-year-old man was referred to our hospital for an abnormal lesion in the left lung discovered on routine health examination. A computed tomography scan of the chest revealed a 14-mm heterogeneous round nodule with surrounding ground-glass opacity in the left lower lobe. The tumor size increased to 18 mm in three weeks, and he developed bloody sputum. TBLC was performed using radial endobronchial ultrasonography and fluoroscopy. An occlusion balloon and prophylactic epinephrine were used to prevent severe bleeding. Histologically, epithelioid cells with solid proliferation, various papillary lesions, and hemosiderin-laden histiocytes were observed. Immunohistochemical staining revealed the histiocytes positive for thyroid transcription factor-1 and vimentin, and the type II pneumocyte-like-cells positive for cytokeratin 7. The tumor was preoperatively diagnosed as a PSP; the patient underwent left basal segmentectomy and consequently, a final diagnosed of PSP was formulated. Conclusion We report the first case of PSP preoperatively diagnosed using TBLC. Therefore, cryobiopsy could be beneficial in the preoperative diagnosis of PSP.
[Introduction]We report a case of subglottic stenosis as a cause of respiratory distress in a patient with end-stage idiopathic dilated cardiomyopathy.[Case presentation]A 41-year-old man was diagnosed with severe tracheal stenosis on imaging examination for heart failure and underwent tracheectomy of the stenosis. Before inducing anesthesia, a veno-arterial extracorporeal membrane oxygenator (VA-ECMO) and intra-aortic balloon pump (IABP) were attached, and the airway was secured with a supraglottic device (SGA) . After the resection at the distal site of tracheal stenosis, operative field intubation was performed. After excision of the stricture, tracheal anastomosis was performed, and oral intubation was switched to complete as planned. Intraoperative SGA controlled breathing had become impossible, but hypoxia and hypercapnia did not occur. The patient's symptoms improved postoperatively. [Conclusion]We performed anesthesia for tracheectomy in a patient with hypocardiac function in which respiratory distress was caused by subglottic tracheal stenosis. Using SGA, VA-ECMO and IABP, the operation could be completed while maintaining stable respiration and circulation.
