- 오은규외 : 항암치료중발생한표층점상각막병증 - 특별한안과병력이없는 56세여자환자 ( 증례 2) 가며칠전부터시작된양쪽눈의이물감을주소로내원하였다. 환자는우측유방의침윤성관세포암종으로우측변형근치유방절제술을시행받고, 파클리탁셀 / 트라스투주맙병합치료를받은병력이있었다. 이후종양의간전이가발견되어 6개월전부터는라파티닙을투약하고있었다. 라파티닙을사용하기이전에본원에서안과검진을받은적이있었는데, 당시에는각막미란이없었다. 우안시력은 20/20, 좌안시력은 20/25이었다. 골드만편평압압계로측정한안압은양안각각 16 mmhg 이었다. 세극등현미경검사에서양안각막에미만성점상의각막미란이관찰되었다. 무방부제인공누액과자가혈청안약을두시간마다 2개월동안양쪽눈에점안한결과, 양안의미만성각막미란은큰변화없이비슷한정도로유지되었다. 마침총 36주의라파티닙치료가완료되어라파티닙은중단하고 4주간무방부제인공누액과자가혈청안약치료를지속하였다. 4주후시행한세극등현미경검사에서양안각막미란은감소하였고, 환자의주관적인불편감도해소되었다 (Fig. 2A-D). 결론 표피성장인자수용체억제제는전이된대장직장암, 유방암, 폐선암종, 두경부편평세포암등다양한종류의종양에널리쓰이는치료제이다. 1,2 표피성장인자수용체억제제가등장한이후에세툭시맙 3 과제페티닙, 10 에를로티닙이 4,8,10 거대속눈썹증이나안와주변발진을유발할수있고, 세툭시맙, 5 에를로티닙, 6 제페티닙 7 이각막미란을유발할수있으며, 세툭시맙 9 과에를로티닙 11 이흉터눈꺼풀겉말림을유발할수있다는것이보고되었다. 오직라파티닙만이아직까지안과적합병증이보고되지않은유일한표피성장인자수용체억제제이다. 표피성장인자는눈물샘에서분비되는데, 표피성장인자수용체는각막의기저상피세포, 각막윤부, 모낭초등에분포한다. 표피성장인자와표피성장인자수용체의결합은각막상피손상의회복과각막의항상성을유지하는데영향을미친다고알려졌다. 12 표피성장인자와표피성장인자수용체와의결합이각막상피회복을촉진하는신호전달체계도보고된바있다. 13 Förster et al 14 은세툭시맙사용에의한각막미란환자에서표피성장인자를점안하는것이각막상피의회복에도움이될수있다는내용을보고하였다. 에를로티닙은 human epidermal growth factor receptor type 1/epidermal growth factor receptor (HER1/EGFR) tyrosine kinase에선택적인길항제이다. 라파티닙은 intracellular tyrosine kinase domains of both Epidermal Growth Factor Receptor (EGFR [ErbB1]) 와 Human Epidermal Receptor Type 2 (HER-2 [ErbB2]) receptor에선택적인길항제이다. ErbB1 과 ErbB2는특히각막표면에많이존재하는데특히 ErbB2는각막상피세포의이동에중요한역할을담당한다고알려졌다. 15 그러므로 ErbB1과 ErbB2 의억제는각막상피세포의유지에큰영향을미칠것이고, 이는증례 2의치료기간이증례 1보다길었던이유가될수있을것이다. 두증례에서각막병증과안구불편감은표피성장인자수용체억제제치료를시작하고나서평균 5개월이후에발생하였다. 기존의보고에따르면표피성장인자수용체억제제치료의안과적합병증은표피성장인자수용체억제제치료를시작하고 3주에서 6개월사이에발생하는것으로보고되었는데, 3-10 이는피부나폐와같은다른장기에합병증이발생하는데소요되는시간과비슷하다. 16,17 피부발진은표피성장인자수용체억제제치료의가장흔한부작용이며대부분의경우, 치료를중단하고한달이내에해소되는것으로알려졌다. 16 피부발진의발생여부와피부발진의중증도는체내표피성장인자억제제의활성도와연관이되어있다. 18 증례 2 환자에서경과관찰중피부발진이발생하였는데, 이는체내에서표피성장인자억제제가피부발진을유발할만큼충분히활성화되어있었다는간접적인증거이다. 표피성장인자수용체억제제치료가종료되고한달후에피부발진과각막미란이함께호전되었다는점도표피성장인자수용체억제제치료와각막미란사이의연관성을시사한다. 본증례에서는각막상피세포의증식과이동을촉진시키기위해무방부제인공누액과자가혈청안약을사용하였다. 자가혈청안약치료는안구건조증에의한표층점상각막병증의치료방법으로대한민국식품의약품안전청의승인을받은치료방법이다. 자가혈청안약은환자의사전동의후에 30-40 ml의혈액을채혈하여 2500 rpm에서 10분간원심분리후, 무균조작으로혈청만취하여생리식염수에 20% 농도로희석하여제조하였다. 19 사람의혈청에는표피성장인자, 전환성장인자-베타, 혈소판유래성장인자, 비타민 A, 섬유결합소, 알부민, P물질이나인슐린성장인자같은신경전달물질이함유되어있다. 20,21 하지만이번증례에서는자가혈청안약에포함된표피성장인자가전신적인표피성장인자수용체억제제의효과를감소시켰다고보기는어려운데, 그이유는에를로티닙과라파티닙은세툭시맙처럼세포표면의표피성장인자수용체에직접작용하는것이아니라, 세포내에침투하여세포내신호전달과정을방해하기때문이다. 6,16 오히려비타민 A나섬유결합소와같은다른혈청성분이각막상피회복에영향을미쳤을것으로 www.ophthalmology.org 295
- 대한안과학회지 2014 년제 55 권제 2 호 - 생각한다. 증례 1의경우, 에를로티닙에의해각막병증이발생할수있다는기존의연구를지지하는국내첫사례이기때문에보고의가치가있다. 증례 2를고려할때, 라파티닙도각막상피의회복을저해하는후보약물이될수있다. 이에저자들은표피성장인자억제제치료중발생한표층각막병증환자에서무방부제인공누액과자가혈청안약으로성공적으로치료한경험을보고하는바이다. 향후충분한수의환자를대상으로전향적인연구를통해표피성장인자억제제치료와표층각막병증의연관관계를밝히는후속연구가필요할것이다.

- 오은규외 : 항암치료중발생한표층점상각막병증 - =ABSTRACT= Superficial Punctate Keratoepitheliopathy Under Treatment with Erlotinib and Lapatinib Eun Kyu Oh, MD 1,2, Dong Hyun Jo, MD 1,2, Mee Kum Kim, MD, PhD 1,2, Won Ryang Wee, MD, PhD 1,2 Department of Ophthalmology, Seoul National University College of Medicine 1, Seoul, Korea Seoul Artificial Eye Center, Seoul National University Hospital Clinical Research Institute 2, Seoul, Korea Purpose: To report the corneal superficial punctate keratoepitheliopathy in 2 patients taking the epidermal growth factor receptor (EGFR) inhibitors, erlotinib and lapatinib, respectively. Case summary: Case 1, who received erlotinib, showed trichomegaly without touching the cornea and diffuse punctate keratoepitheliopathy. Corneal epitheliopathy and the corresponding symptoms resolved after discontinuation of the drug then recurred with reapplication. Case 2 presented diffuse corneal punctate epithelial erosions that developed without any cilia involvement after the patient was administered lapatinib. The visual acuity of both patients was not severely diminished and keratoepitheliopathy was mostly resolved with the treatment of preservative-free artificial tears and autologous serum eye drops. Conclusions: Erlotinib and lapatinib are both likely to cause visually tolerable corneal punctate keratoepitheliopathy which can be resolved with appropriate topical treatment.
