LETTER TO THE EDITOR Quandaries of the Irradiated Larynx In his review article, P.C. O’Brien has very succinctly addressed the subject and reviewed pertinent literature [1].

Absent in this author’s analysis is a very important factor that can add to the local injury to the larynx and hypo- pharynx, especially following radiation therapy. I refer to laryngeal pathology attributable to gastroesophageal re- flux disease (GERD) which, in my opinion, is not an insignificant cause for morbidity during and following radiotherapy for cancer of the upper aerodigestive tract and especially the larynx [2–6]. I wish to second a word of caution mentioned by the author, and it refers to taking biopsies of the larynx with- out a strong clinical suspicion for persistent or recurrent tumor, especially during the immediate post-treatment period and up to 60–90 days, depending on the location of the primary cancer and the treatment fractionation used by the radiotherapist. Ill-advised biopsies can often be the precipitating factor for major laryngeal necrosis and contribute to a significant morbidity in the recovery from treatment. Any practitioner taking care of patients with carci- noma of the larynx should be aware of the multiple in- sults that can afflict this organ and should rule out sig- nificant causes for edema and necrosis before proceeding with aggressive biopsies unless there is strong clinical evidence for tumor recurrence.

LETTER TO THE EDITOR

Quandaries of the Irradiated Larynx

In his review article, P.C. O’Brien has very succinctlyaddressed the subject and reviewed pertinent literature[1]. The issue is not an insignificant one, and the concernfor recurrence of cancer is heightened when there isedema, and certainly in the event of necrosis of laryngealstructures. The author has mentioned some of the causesfor persistent edema and necrosis, and the best known arecontinued smoking and possibly consumption of alcohol.Absent in this author’s analysis is a very important factorthat can add to the local injury to the larynx and hypo-pharynx, especially following radiation therapy. I refer tolaryngeal pathology attributable to gastroesophageal re-flux disease (GERD) which, in my opinion, is not aninsignificant cause for morbidity during and followingradiotherapy for cancer of the upper aerodigestive tractand especially the larynx [2–6].

I wish to second a word of caution mentioned by theauthor, and it refers to taking biopsies of the larynx with-out a strong clinical suspicion for persistent or recurrenttumor, especially during the immediate post-treatmentperiod and up to 60–90 days, depending on the locationof the primary cancer and the treatment fractionationused by the radiotherapist. Ill-advised biopsies can oftenbe the precipitating factor for major laryngeal necrosisand contribute to a significant morbidity in the recoveryfrom treatment.

Any practitioner taking care of patients with carci-noma of the larynx should be aware of the multiple in-

sults that can afflict this organ and should rule out sig-nificant causes for edema and necrosis before proceedingwith aggressive biopsies unless there is strong clinicalevidence for tumor recurrence.
