We investigated the safety and efficacy of pemetrexed monotherapy in patients with lung adenocarcinoma and various renal conditions, including chronic kidney disease. We also analyzed whether baseline renal function affected progression-free survival (PFS). We retrospectively analyzed 71 patients who received maintenance-and second-line pemetrexed monotherapy. Patients were divided into two groups according to estimated glomerular filtration rate (eGFR): fair eGFR (>60 mL/min/1.73 m²) and lower eGFR (59 mL/min/1.73 m² or less). The safety and efficacy were evaluated for each group. Median ages were 73.2 years in the lower eGFR group (n=28) and 64.5 years in the fair eGFR group (n=43). Patients with a lower eGFR achieved a median PFS of 4.7 months, while the median PFS for patients with a fair eGFR was 2.7 months. The difference between the two groups was not statistically significant (P=0.075). Both groups showed treatment-related low-grade hematological and non-hematological adverse events. Pemetrexed monotherapy is safe and effective in patients with lung adenocarcinoma with a lower eGFR.

25년령의 암컷 캘리포니아 바다사자(Zalophus californianus)가 고령으로 인하여 분리 사육되고 있었다. 침울, 식욕부진, 쇠약, 체중감소 등의 임상증상을 보인 후 폐사하였고, 부검을 실시하였다. 육안적으로 양측 신장은 창백하고 직경 0.5-3 cm의 종양 결절이 다발성으로 관찰되었다. 간과 비장, 소장에서도 한계가 명료하고 크기가 다양하며 단단한 전이성 종양 결절이 다발성으로 존재하고 있었다. 본 예는 육안 및 병리조직학적 소견을 근거로 신장과 비장, 소장의 전이를 동반한 신장세포암종으로 진단할 수 있었다. 국내 캘리포니아 바다사자에서의 신장암의 보고는 드물며 향후 임상적으로 바다사자의 진료와 진단에 도움이 되고자 본 논문을 발표하는 바이다.

We have synthesized a novel platinum(II) coordination complex containing cis-1,2-diaminocyclohexane (DACH) as a carrier ligand and 1,3-dichloropropane (DCP) as a leaving group. A new series of [Pt(cis- DACH)(DCP)](PC) was evaluated for its cytotoxic activity on MKN-45 human gastric adenocarcinoma cells and normal primary cultured kidney cells. The new platinum complex has demonstrated high efficacy in the cytotoxicity against MKN-45/P, MKN-45/ADM and MKN-45/CDDP cell-lines. The cytotoxicity of PC against rabbit proximal renal tubular cells, human renal cortical cells and human renal cortical tissues, determined by MTT assay, the $[^3H]-thymidine$ uptake and glucose consumption tests, was found to be quite less than those of cisplatin. Based on these results, this novel platinum(II) coordination complex appears to be better for improving antitumor activities with low nephrotoxicity and is a valuable lead in the development of new, clinically available anticancer chemotherapeutic agents.

Most common metastatic tumors of the thyroid gland are squamous cell carcinoma of head and neck region, adenocarcinoma of breast and lung, malignant melanoma, and renal cell carcinoma of kidney in order of frequency. Metastasis from gastrointestinal tract to the thyroid gland rarely occurs. We experienced a case of fine needle aspiraton cytology of metastatic adenocarcinoma of both thyroid glands from the colon. Cytologic smears showed picket-fence like arrangement of nuclei of carcinoma cells and syncytial type of tissue fragments with acinar pattern on necrotic or mucoid background.

횡문근양 종양은 윌름씨 종양의 횡문근육종 형태의 드문 변종 아형으로 여겨져 왔으나, 1989년에 신장에서 발생한 황문근양 종양이 처음으로 기술된 이후 위장관에서도 드물게 보고되고 있다. 적절한 치료는 근치적 절제술이여 술후 보조 항암요법의 효과는 보고되지 않았다. 신장외 횡문근양 종양은 신장에서 발생한 횡문근양 종양과는 경과가 다르며 불량한 예후를 보인다. 신장외 횡문근양 종양 중에서도 횡문근양 형태의 미분화 위 선암은 매우 드물며 예후가 불량하다. 63세 남자 환자가 위 체부의 대만부에 발생한 종괴로 위전절제술을 시행받았으며, 병리조직 결과에서 횡문근양 형태의 미분화 위 선암이 진단되었다. 이에 본 저자들은 면역조직화학적으로 진단된 횡문근양 형태를 보이는 미분화 위 선암을 경험하여 증례를 보고하는 바이다.

신장의 점액성 선암은 신우신배계에서 발생하는 매우 드문 낭성 악성 종양으로 예후가 좋지 않다. 임상 증상 및 영상학적 소견이 비특이적이어서 수술 전 진단이 매우 어렵다. 저자들은 69세 남자 환자의 말굽신장에서 발생한 원발성 점액성 선암의 증례를 CT 소견을 중심으로 보고한다. 이 종양은 불규칙한 벽비후와 다수의 석회화 및 중격을 동반한 복합 낭종으로 관찰되었고 수술 후 복막강거짓점액종으로 진행하였다.

The use of cisplatin is limited by severe side effects such as renal toxicity. Our platinum-base drug discovery is aimed at developing drugs capable of diminishing toxicity and improving antitumor activity. We synthesized new Pt (II) complex analogue [Pt (cis-DACH)(DPPP)]. 2NO$_3$ (PC) containing cis-1,2-diaminocyclohexane as a carrier ligand and 1,3-bis(diphenylphosphino) propane as a leaving group. Furthermore, nitrate was added to improved the solubility. In this study, its structure was determined and its antitumor activity against SKOV-3 and NIH-OVCAR-3 human ovarian adenocarcinoma, and in vitro cytotoxicity was determined against primary cultured rabbit kidney proximal tubular and renal cortical cells of human kidney using colorimetric MTT assay. PC demonstrated acceptable antitumor activity against SKOV-3 and NIH-OVCAR-3 human ovarian adenocarcinoma and significant activity as compared with that of cisplatin. The toxicity of PC was found quite less than that of cisplatin using MTT and $^3$H-thymidine uptake tests in rabbit proximal tubular cells and human kidney cortical cells. PC was used for human cortical tissue in 7 weeks hitoculture by the glucose-consumption tests. We determined that the new platinum drug has lower nephrotoxicity than cisplatin. Based on these results, this novel platinum (II) complex compound (PC) represent a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low nephrotoxicity.

Objective: To study the incidence, types and distribution pattern of malignant tumors in renal transplant recipients at a single center in Pakistan. Materials and methods: This retrospective study was conducted at Sindh Institute of Urology and Transplantation (SIUT) and included all transplant patients on regular follow-up from November 1986 to December 2008. The original biopsy reports and case files of all patients who developed posttransplant malignancies were reviewed and relevant demographic, clinical, radiological, and histopathological data were retrieved and analyzed. SPSS version 10.0 was used for statistical analysis. Results: Over 22 years of study period, 1816 renal transplants were carried out at our center. Among these, 44 patients developed malignancies constituting an overall incidence rate of 2.4%. All patients in this study were males with a mean age of $34.9{\pm}9.5$ years (range: 9 to 60 years). The most common type of malignancy was lymphoma (27 patients, 61.4%), followed by Kaposi's sarcoma (11 patients, 25%) and skin malignancies (3 patients, 6.8%). One case each of adenocarcinoma of the gallbladder, acute myeloid leukemia (AML), conjunctival carcinoma-in-situ and seminoma were also diagnosed. Conclusion: Posttransplant malignancies occurring in our renal transplant recipients show different incidence rates and patterns as compared with western studies.

We have synthesized a novel platinum (II) coordination complex containing trans-ι-1,2-diaminocyclohexane (DACH) as a carrier ligand and 1,2-bis (diphenylphosphino)ethane (DPPE) as a leaving group. In addition, nitrate was added to improve the water-solubility. A new series of [Pt (trans-ι-DACH) (DPPE)].2NO$_3$(PC) was evaluated for its cytotoxic activity on MKN-45 human gastric adenocarcinoma cells and normal primary cultured kidney cells. PC has demonstrated high levels of cytotoxicity against MKN-45/S, MKN-45/ADR and MKN-45/CDDP cells. The cytotoxicity of PC against rabbit proximal renal tubular cells, human renal cortical cells, and human renal cortical tissues, determined using the MTT assaying technique, the ($^3$H)-thymidine uptake and the glucose consumption tests, was found to be quite less than those of cisplatin. Based on these results, this novel platinum (II) coordination complex appears to be better for improving antitumor activities with low nephrotoxicity and is a valuable lead in the development of new clinically available anticancer chemotherapeutic agents.
