Multicenter Study Observational Study
Chemotherapy-induced nausea and vomiting is less controlled at delayed phase in patients with esophageal cancer: a prospective registration study by the CINV Study Group of Japan.
Chemotherapy is an indispensable therapeutic approach for esophageal cancer. Although chemotherapy-induced nausea and vomiting (CINV) is one of the most crucial adverse events, the current state of CINV in patients with esophageal cancer remains unclear. This multicenter prospective observational study analyzed data for 192 patents with esophageal cancer who underwent moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC). ⋯ Adherence to antiemetic guidelines effectively controls vomiting but is less effective against delayed CINV in both HEC and MEC patients. Identification of individual risk factors, such as female sex, will help develop personalized treatments for CINV. In the clinical setting for esophageal cancer, regimens that include nedaplatin might need to be treated as HEC.

Nomograms incorporating multiple prognostic factors are useful for individualized estimation of survival in cancer patients. However, nomograms for the prediction of pathological complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) in patients with esophageal cancer are scarce. Here, we describe the development of a nomogram for predicting pCR after nCRT in patients with esophageal squamous cell carcinoma (ESCC). ⋯ The following variables were included in the nomogram: (i) age, (ii) pretreatment tumor length, (iii) history of head and neck cancer, (iv) post-nCRT albumin levels, and (v) post-nCRT endoscopic findings coupled with endoscopic biopsy results. The bias-corrected c-statistic and AUROC of the internal and external validation sets were 0.77 and 0.747, respectively. Our nomogram showed a good performance for predicting pCR after nCRT in ESCC patients.

Neoadjuvant chemotherapy (NAC) and chemoradiotherapy have been shown to extend postoperative survival, and preoperative therapy followed by esophagectomy has become the standard treatment worldwide for patients with esophageal squamous cell carcinoma (ESCC). The Japan Clinical Oncology Group 9907 study showed that NAC significantly extended survival in advanced ESCC, but the survival benefit for patients with clinical stage III disease remains to be elucidated. We compared the survival rates of NAC and upfront surgery in patients with clinical stage III ESCC. ⋯ In clinical stage III ESCC patients, no significant difference in OS was observed between NAC and upfront surgery. Although potential patient selection bias might be a factor in this retrospective analysis, the noncurative resection rate was higher after NAC than after upfront surgery. The survival benefit of more intensive NAC needs to be further evaluated.

The effect of high-resolution esophageal manometry (HRM) on oxygen saturation (SaO2) and hemodynamic function has not been previously evaluated. This was a prospective study of consecutive patients referred for HRM. Demographic and clinical data were collected on all patients. ⋯ The appearance of desaturation (SaO2 <95%) during intubation was associated with a lower basal SaO2; desaturation during HRM and 5 minutes after HRM was associated with a higher age, a higher BMI and a lower basal SaO2. HRM decreases SaO2 and increases heart rate primarily during the insertion of the probe, as part of the standard stress response and therefore HMR can be considered a safe procedure. However, in older and overweight patients, respiratory parameters should be monitored.
