Aims: To explore efficacy and side effects of intrapleural or intraperitoneal lobaplatin for treating patients with malignant pleural or peritoneal effusions. Methods: Patients in Jiangsu Cancer Hospital and Research Institute with cytologically confirmed solid tumors complicated with malignant pleural effusion or ascites were enrolled into this study. Lobaplatin (20-30 $mg/m^2$) was intrapleurally or intraperitoneally infused for patients with malignant pleural effusion or ascites. Results: From 2012 to 2013, intrapleural or intraperitonea lobaplatin was administered for patients with colorectal or uterus cancer who were previous treated for malignant pleural effusion or ascites. Partial response was achieved for them. Main side effects were nausea/vomiting, and bone marrow suppression. No treatment related deaths occurred. Conclusion: Intrapleural or intraperitoneal infusion of lobaplatin is a safe treatment for patients with malignant pleural effusion or ascites, and the treatment efficacy is encouraging.

Purpose: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been shown to improve survival in select patients with gastric cancer and peritoneal metastases. It remains unclear, however, whether this multimodal treatment protocol is also beneficial for signet-ring cell gastric cancer (SRC) patients with peritoneal metastases. Materials and Methods: Clinical data of patients scheduled for upfront systemic chemotherapy consisting of 5-FU (2,600 $mg/m^2$), folinic acid (200 $mg/m^2$), docetaxel (50 $mg/m^2$), and oxaliplatin (85 $mg/m^2$) followed by CRS and HIPEC using cisplatin (50 $mg/m^2$) at the Comprehensive Cancer Center, University Hospital T$\ddot{u}$bingen, Germany were retrospectively analyzed. Results: Eighteen consecutive patients for whom irresectability has been ruled out by a computed tomography scan were enrolled. However, complete cytoreduction could only be achieved in 72% of patients. When categorizing patients with respect to the completeness of cytoreduction, we found no difference between both groups considering tumor- or patient-related factors. The overall complication rate following complete cytoreduction and HIPEC was 46%. Within a median follow-up of 6.6 (0.5~31) months, the median survival for CRS and HIPEC patients was 8.9 months as opposed to 1.1 months for patients where complete cytoreduction could not be achieved. Following complete cytoreduction and HIPEC, progression-free survival was 6.2 months. Conclusions: In SRC with peritoneal metastases, the prognosis appears to remain poor irrespective of complete CRS and HIPEC. Moreover, complete cytoreduction could not be achieved in a considerable percentage of patients. In SRC, CRS and HIPEC should be restricted to highly selective patients in order to avoid exploratory laparotomy.

복막암종증(Peritoneal carcinomatosis)은 복강내에 암세포가 파종되어 벽쪽 복막과 내장쪽 복막 표면에 악성세포가 축적되는 상태로 정의할 수 있으며, 이것은 암성복수와도 관련 있다. 일반적으로 복막암종증은 원발암의 전이성 암과 유사하게 치료하나 같은 원발암의 다른 장기로의 전이암과는 달리 예후가 좋지 않다. 보존적 치료만 했을 경우 복막암종증 환자의 중앙생존기간은 3-6개월이다. 복막암종증은 예후가 좋지 않고 치료 방법이 제한적이어서 일선에서 치료하는 내과 의사에겐 여전히 어려운 과제이기도 하다. 최근에 이와 관련된 치료 방법이 많이 연구되어 육안적 병소제거술 및 복막절제술(cytoreductive surgery with peritonectomy)과 함께 조기 수술 후 복강내 화학요법(early postoperative intraperitoneal chemotherapy, EPIC) 또는 수술 중 복강내 온열화학요법(hyperthermic intraperitoneal chemotherapy, HIPEC)을 시행하여 생존율을 향상시키고 있다. 본 논문에서는 복막암종증의 전반적인 특징, 증상, 예후 및 진단과 수술적 방법, 항암 화학요법 등의 치료법에 대하여 알아보고자 한다.

네 살령의 암컷 시츄견이 복부 팽만으로 내원하여 조직검사 결과 cystic papillary adenocarcinoma로 진단되었으며, 복강 장간막으로의 전이도 확인되었다. 난소 자궁 적출술을 실시하고 1달 후, 복수를 제거한 후 cisplatin을 (50 $mg/m^2$)을 0.9% 생리식염수(250 $ml/m^2$)에 희석하여 복강내로 주입하였다. 치료기간 동안 3번의 재발이 있었으나, 임상증상의 개선이 매우 뚜렷하였으며, 특별한 부작용을 보이지 않고 진단 후 33개월 간 건강 상태를 유지할 수 있었다. 그러나 11번의 항암 치료 이후에 복수와 더불어 흉수가 병발하였고, 신부전증도 동반하였다. 수액요법과 대증치료의 일환으로 복강, 흉강 천자도 실시하였으나 개선을 보이지 않고 환자는 폐사하였다. 복강 내 cisplatin의 투여법은 난소종양으로 인한 악성 복수, 흉수를 치료하는데 효과적인 완화요법으로 쓰일 수 있을 것으로 사료된다. 본 증례는 복강전이를 동반한 악성 난소 종양이 발생한 환자를 복강 내 cisplatin투여를 통해 효과적으로 치료한 한국에서의 첫 번째 보고이다.

F-18 FDG-PET/CT는 위암의 재발여부를 평가하는데 있어서 이용될 수 있으나 위양성을 일으키는 경우가 종종 보고된다. 저자들은 위암으로 위절제술과 Mitomycin C를 이용한 복강 내 화학요법 시행 후 F-18 FDG-PET/CT상 위양성의 복강 내 활성화 탄소 육아종을 경험하였다. 46세 남자환자는 수술 후 6개월째 시행한 CT상 우측 대장 뒤에서 종물이 발견되었으나 크기 변화 없다가 36개월째 크기의 증가를 보여 시행한 F-18 FDG-PET/CT상 전이 종양이 의심되었다. 진단적 개복술을 시행하여 제거한 종양은 조직학적 검사상 활성화 탄소 육아종으로 진단되었다. 이처럼 복강 내 화학요법을 시행한 환자의 F-18 FDG-PET/CT의 해석에 있어서 활성화 탄소 육아종에 의한 위양성 소견의 가능성을 염두에 두어야 할 것이다.

Background: This study evaluated occupational exposure levels of doxorubicin in healthcare workers performing rotational intraperitoneal pressurized aerosol chemotherapy (PIPAC) procedures. Methods: All samples were collected during PIPAC procedures applying doxorubicin to an experimental animal model (pigs). All procedures were applied to seven pigs, each for approximately 44 min. Surface samples (n = 51) were obtained from substances contaminating the PIPAC devices, surrounding objects, and protective equipment. Airborne samples were also collected around the operating table (n = 39). All samples were analyzed using ultra-high performance liquid chromatography-mass spectrometry. Results: Among the surface samples, doxorubicin was detected in only five samples (9.8%) that were directly exposed to antineoplastic drug aerosols in the abdominal cavity originating from PIPAC devices. The telescopes showed concentrations of 0.48-5.44 ng/cm² and the trocar showed 0.98 ng/cm² in the region where the spraying nozzles were inserted. The syringe line connector showed a maximum concentration of 181.07 ng/cm², following a leakage. Contamination was not detected on the surgeons' gloves or shoes. Objects surrounding the operating table, including tables, operating lights, entrance doors, and trocar holders, were found to be uncontaminated. All air samples collected at locations where healthcare workers performed procedures were found to be uncontaminated. Conclusions: Most air and surface samples were uncontaminated or showed very low doxorubicin concentrations during PIPAC procedures. However, there remains a potential for leakage, in which case dermal exposure may occur. Safety protocols related to leakage accidents, selection of appropriate protective equipment, and the use of disposable devices are necessary to prevent occupational exposure.

Background: This study was to evaluate the survival of patients with pleural and intraperitoneal malignant mesothelioma and to investigate the efficacy of chemotherapy (CT) as well as radiotherapy (RTH) and surgery compared to best supportive care (BSC). Materials and Methods: Forty patients with malignant mesothelioma (38 with pleural and 2 with intraperitoneal) were enrolled. Twenty seven patients underwent (CT) chemotherapy of which 2 also received (RTH) and surgery was only for biopsy in 15/40. Combination chemotherapy included cisplatin-gemcitabine, cisplatin-navelbine and cisplatin (or carboplatin) with premetrexed. Thirteen patients received only best supportive care. Results: A total of 12 (30%) patients were male, and 28 (70%) female. Median age was 54.0 years and the male/female ratio was 1/2.33 (P=0.210). Residential exposure played a major role in two regions, Helwan and Shoubra, in 20% and 15%, respectively. Overall mean survival time was $13.9{\pm}2.29$ months. That for patients who had received best supportive care was $7.57{\pm}1.85$ months, for chemotherapy was $16.5{\pm}3.20$ months, and multimodality treatment regimen $27{\pm}21.0$ months (P=0.028). Kaplan-Meier survival did not significantly vary for sex, residence and the pathological types epithelial, mixed and sarcomatous. The median survival for performance status and treatment modalities was significant (P=0.001 and 0.028). Best supportive care using opioids with a mean dose of 147.1 mg (range 0-1680) of morphine sulphate produced good subjective response and reasonable quality of life but did not affect survival. Conclusions: We conclude that CT prolongs survival compared to BSC in patients with malignant mesothelioma. Moreover, using escalating doses of opioids provides good pain relief and subjective responses.

Neutropenia is a major dose-limiting side effect of cancer chemotherapy. The therapeutic effect of HM 10411 was examined on neutropenia caused by anticancer agents. Neutropenia in normal ICR mice was induced by a single combined intraperitoneal injection of 130 mg/kg of cyclophosphamide (CPA). 4.5 mg/kg of doxorubicin (DXR). and 1 mg/kg of vincristine (VCR) on day O. Neutropenia in tumor-bearing mice was made by a single intraperitoneal injection of 200 mg/kg of cyclophosphamide (CPA) into BALB/c mice bearing Colon 26 adenocarcinoma at 7 day after tumor implantation. HM 10411 or filgrastim (100 $\mu\textrm{g}$/kg/day) was subcutaneously administered for 5 consecutive days starting 1 day after injection of anticancer agents in order to stimulate neutrophil production. Injection of HM 10411 accelerated the recovery from these anticancer drug-induced neutropenia. In normal and tumor-bearing mice. neutrophil production efficacy of HM 10411 was similar than that of filgrastim. These results suggest that HM 10411 could be useful in the clinical treatment for neutropenia induced by anticancer agents.

Background: Chemotherapy-induced peripheral neuropathy is a major side effect of anti-cancer drugs, and our knowledge of its mechanisms is lacking. Several models for chemotherapy-induced neuropathy have been introduced. However, the outcomes of these models differ significantly among laboratories. Our object was to create a model of chemotherapy-induced neuropathy in rats with cancer. Methods: Female Sprague-Dawley rats were used. Mammary rat metastasis tumor (MRMT-1) cells were implanted subcutaneously in rats. Chemotherapy-induced peripheral neuropathy was induced by injection of cisplatin once a day for four days. The responses to mechanical and thermal stimuli were examined using von Frey filaments, acetone, and radiant heat. Results: Cisplatin (2 mg/kg/day) produced mechanical allodynia, while it did not induce cold allodynia or thermal hyperalgesia. This dose of cisplatin could work successfully against cancer. Body weight loss was not observed in cisplatin-treated rats, nor were other abnormal behaviors noted in the same rats. Conclusions: Repeated injection of intraperitoneal cisplatin induced peripheral neuropathic pain in rats. Thus, this type of rat model has broad applicability in studies related to searching for the mechanism of cisplatin-induced mechanical allodynia and agents for the treatment of neuropathic pain.
