Periodic pharyngolaryngoscopy detects early head and neck cancer and improves survival in esophageal cancer Akihito Watanabe, MD, Masao Hosokawa, MD, Masanobu Taniguchi, MD, Shigeyuki Sasaki, MD The Annals of Thoracic Surgery Volume 76, Issue 5, Pages (November 2003) DOI: /S (03)

Fig 1 Kaplan-Meier survival curves for patients with esophageal cancer without squamous cell carcinoma of the head and neck (EC group) and patients with esophageal cancer and metachronous or synchronous development of squamous cell carcinoma of the head and neck (EC+SCCHN group). There was no significant difference between the two groups. The Annals of Thoracic Surgery , DOI: ( /S (03) )

Fig 2 Kaplan-Meier survival curves for patients undergoing surgical resection. There was no significant difference between the two groups. (EC group = patients with esophageal cancer without squamous cell carcinoma of the head and neck; EC+SCCHN group = patients with esophageal cancer and metachronous or synchronous development of squamous cell carcinoma of the head and neck.) The Annals of Thoracic Surgery , DOI: ( /S (03) )

Fig 3 Kaplan-Meier survival curves for patients receiving periodic pharyngolaryngoscopy. There was no significant difference between the two groups. (EC group = patients with esophageal cancer without squamous cell carcinoma of the head and neck; EC+SCCHN group = patients with esophageal cancer and metachronous or synchronous development of squamous cell carcinoma of the head and neck.) The Annals of Thoracic Surgery , DOI: ( /S (03) )

Fig 4 Kaplan-Meier survival curves for patients undergoing periodic pharyngolaryngoscopy (periodical endoscopic screening [+]) and patients without screenings (periodical endoscopic screening [−]). The survival rate for patients receiving screening was significantly better than that for the other group (**p < 0.001). The Annals of Thoracic Surgery , DOI: ( /S (03) )
6
Fig 5 Kaplan-Meier survival curves for patients undergoing surgical resection and then followed with (periodical endoscopic screening [+]) or without (periodical endoscopic screening [−]) periodic pharyngolaryngoscopy. Note that only patients who had surgical resection are included. The survival rate for patients undergoing periodic screening was significantly better than that of the other group (**p < 0.01).
