In this study, gemcitabine (Gem)-Poly(L-lactic acid) (PLLA) conjugates were synthesized through an amide linkage reaction. Then, the microparticles of Gem-PLLA/PLLA blends containing gemcitabine were prepared using a supercritical fluid process, called aerosol solvent extraction system (ASES). Gemcitabine-loaded Gem-PLLA/PLLA microparticles obtained from the ASES process showed a spherical shape. The amount of gemcitabine released after 30 day incubation in a phosphate buffer solution of pH 7.4 was about 90% of the total amount of gemcitabine present in the product.

Radiation recall is an uncommon phenomenon in which administration of a chemotherapy or another systemic agent induces an acute inflammatory reaction in previously irradiated tissues, often weeks to years after completion of radiotherapy. Gemcitabine can induce an inflammatory reaction within an area of prior radiation. Radiation recall is known to medical oncologists, however only few cases have been reported in Korean journals, therefore physiatrist who diagnose and treat the treatment-related physical impairments of cancer patients must know about it. We emphasize the importance of knowledge of this phenomenon when considering the differential diagnosis of painful limb edema in a patient who has received cancer treatment.

In this study, gemcitabine-loaded methoxy poly(ethylene glycol)-b-poly(L-lactide) (MPEG-PLLA) microparticles with different PEG block lengths were prepared by a W/O/W double emulsion technique. The present study focuses on the investigation of the influence of various preparative parameters such as the ratio of internal water phase and oil phase, polymer concentration, solvent composition of organic phase and salt concentration of external water phase on the morphology and encapsulation efficiency of the microparticles. The microparticles fabricated at high volume ratios of internal water phase to oil phase and at high polymer concentrations showed a relatively high encapsulation efficiency and low porosity. When a dichloromethane/ethyl acetate mixture was used as solvent, both the encapsulation efficiency and drug loading of the microparticles decreased as the level of ethyl acetate increased. The addition of a salt (NaCl) to the external water phase significantly improved the encapsulation efficiency up to 40%, and the microparticles became more spherical with their size and porosity decreased.

췌장암은 예후가 불량한 암으로 진단 당시 진행된 상태로 수술적 치료의 적응증이 되지 못해 고식적 항암 치료를 받는 경우가 대부분이다. 진단 당시 전이성 병변을 동반한 췌장암인 경우 예후가 좋지 않을 것으로 예상하지만 고식적 목적으로 항암치료를 한 결과 매우 좋은 반응을 보였던 증례를 문헌 고찰과 함께 보고한다.

췌장암은 예후가 매우 불량한 대표적인 암이며, 특히 전이성 췌장암의 경우 생존기간이 3-6개월에 불과하다. 대부분의 췌장암 치료는 항암화학요법이 근간을 이루지만 수술적 치료 이외에 항암화학요법이나 방사선 치료에는 반응이 미미한 것으로 알려져 있다. 저자들은 다발성 혈관 침범과 복강 내 림프절 전이를 보이는 수술이 불가능한 진행성 췌장암에서 젬시타빈 단독 항암화학요법과 고식적 방사선 치료, 그리고 병행한 사이버나이프 추가 치료로 7년 이상의 장기 생존을 보인 증례를 경험하였다. 추적관찰 중 한 차례의 재발과 병발한 원발성 폐암이 확인되었으나, 이 역시 사이버나이프 치료 후 완전 관해를 보인 드문 증례기에 문헌고찰과 함께 보고하는 바이다.
