ABSTRACT

The symposium on “Oncology Leadership in Asia” was held as part of the official program of the 42nd Annual Meeting of the Korean Cancer Association with International Cancer Conference. Given the increasing incidence of cancer in all countries and regions of Asia, regardless of developmental stage, and also in light of the recognized need for Asian countries to enhance collaboration in cancer prevention, research, treatment and follow-up, the symposium was held with the aim of bringing together oncology specialists from eight countries and regions in Asia to present the status in their own national context and discuss the key challenges and requirements in order to establish a greater Asian presence in the area of cancer control and research. The task of bringing together diverse countries and regions is made all the more urgent in that while Asia now accounts for more than half of all new cancer cases globally, clinical guidelines are based predominantly on practices adopted in Western countries, which may not be optimized for unique ethnic, pharmacogenomic and cultural characteristics in Asia. Recognizing the need for Asia to better gather information and data for the compilation of Asia-specific clinical guidelines, the participants discussed the current status in Asia in the national and regional contexts and identified future steps towards integrated and collaborative initiatives in Asia. A key outcome of the symposium was a proposal to combine and integrate the activities of existing pan-Asian societies, including the Asian Pacific Federation of Organizations for Cancer Research and Control (APFOCC) and Asian Clinical Oncology Society (ACOS). Further proposals included the expansion of pan-Asian society membership to include individuals and the essential need to encourage the participation of young researchers in order to ensure self-sustainability of cancer control efforts in the future.

ABSTRACT

PURPOSE: Hypermethylation of the CpG island of p16(INK4a) occurs in a significant proportion of colorectal cancer (CRC). We aimed to investigate its predictive role in CRC patients treated with 5-fluorouracil, leucovorin, irinotecan (FOLFIRI), and cetuximab. MATERIALS AND METHODS: Pyrosequencing was used to identify KRAS mutation and hypermethylation of 6 CpG island loci (p16, p14, MINT1, MINT2, MINT31, and hMLH1) in DNA extracted from formalin-fixed paraffin-embedded specimens. Logistic regression and Cox regression were performed for analysis of the relation between methylation status of CpG island methylator phenotype (CIMP) markers including p16 and clinical outcome. RESULTS: Hypermethylation of the p16 gene was detected in 14 of 49 patients (28.6%) and showed significant association with KRAS mutation (Fisher exact, p=0.01) and CIMP positivity (Fisher exact, p=0.002). Patients with p16-unmethylated tumors had significantly longer time to progression (TTP; median, 9.0 months vs. 3.5 months; log-rank, p=0.001) and overall survival (median, 44.9 months vs. 16.4 months; log-rank, p=0.008) than those with p16-methylated tumors. Patients with both KRAS and p16 aberrancy (n=6) had markedly shortened TTP (median, 2.8 months) compared to those with either KRAS or p16 aberrancy (n=11; median, 8.6 months; p=0.021) or those with neither (n=32; median, 9.0 months; p < 0.0001). In multivariate analysis, KRAS mutation and p16 methylation showed independent association with shorter TTP (KRAS mutation: hazard ratio [HR], 3.21; p=0.017; p16 methylation: HR, 2.97; p=0.027). CONCLUSION: Hypermethylation of p16 was predictive of clinical outcome in metastatic CRC patients treated with cetuximab and FOLFIRI, irrespective of KRAS mutation.

ABSTRACT

PURPOSE: This study was conducted to identify the effects of depression on the survival of patients with cancer over a 10 year period. METHODS: A retrospective review was conducted to examine survival of 218 patients with stomach, colorectal and breast cancer, who had been treated for cancer from 2002 to 2011. Depression was assessed by using the Symptom Check List-90 Revision in 2002, and hope, fighting spirit and other potential confounders were also measured to control for their effects on the association between depression and the survival time. Data on survival were collected from the Statistics Korea and also from medical record in 2011. Kaplan-Meier survival analysis and Cox proportional hazard regression model were used to examine if depression affected survival. RESULTS: The total number of death was 106, and the non-survivors scored higher on depression than survivors. Depression was found to be one of the influencing factors on survival from cancer. CONCLUSION: Depression was significantly associated with the increased risk of death in cancer patients. Further research is needed to identify in details which type of emotional interventions can extend the survival time of cancer patients in depression.

ABSTRACT

PURPOSE: Colorectal cancer patients with liver-confined metastases are classified as stage IV, but their prognoses can differ from metastases at other sites. In this study, we suggest a novel method for risk stratification using clinically effective factors. MATERIALS AND METHODS: Data on 566 consecutive patients with colorectal liver metastasis (CLM) between 1989 and 2010 were analyzed. This analysis was based on principal component analysis (PCA). RESULTS: The survival rate was affected by carcinoembryonic antigen (CEA) level (p < 0.001; risk ratio, 1.90), distribution of liver metastasis (p=0.014; risk ratio, 1.46), and disease-free interval (DFI; p < 0.001; risk ratio, 1.98). When patients were divided into three groups according to PCA score using significantly affected factors, they showed significantly different survival patterns (p < 0.001). CONCLUSION: The PCA scoring system based on CEA level, distribution of liver metastasis, and DFI may be useful for preoperatively determining prognoses in order to assist in clinical decisionmaking and designing future clinical trials for CLM treatment.

ABSTRACT

PURPOSE: The combination of gemcitabine and docetaxel (GD) is used to effectively treat patients with soft tissue sarcoma (STS). It is widely considered that the conventional doses used are too high for long term use and many patients must discontinue GD treatment due to its toxicity. Therefore, to determine the appropriate dose meeting acceptable efficacy results, while minimizing toxic side effects, we treated patients with a weekly infusion of GD (weekly GD). MATERIALS AND METHODS: A total of 22 patients presenting a variety of STSs were treated at Yonsei Cancer Center. All patients had metastatic or recurrent cancer and had previously received doxorubicin and ifosfamide combination chemotherapy. In all cases, gemcitabine (1,000 mg/m2) and docetaxel (35 mg/m2) were administered intravenously on days 1 and 8 of a 21-day cycle. We retrospectively reviewed the medical records of these patients. RESULTS: The response rate was 4.5%, with one patient diagnosed with leiomyosarcoma having a partial response, and the disease control rate was 40.9%. The median progression-free survival (PFS) duration was 2.7 months and the PFS was correlated with the treatment response to a weekly GD. The median overall survival (OS) duration was 7.8 months and the OS was correlated with histology. There was no significant difference in OS between patients who received weekly GD as a 2nd line chemotherapy and those who received 3rd line or more. Treatment was generally well tolerated. CONCLUSION: Weekly GD was well tolerated and showed moderate efficacy, indicating that this could be a reasonable option as a salvage treatment for metastatic STS.

ABSTRACT

PURPOSE: We investigated the clinicopathologic information of patients with gastric cancer with multiple primary cancers (GC-MPC) of three or more sites. MATERIALS AND METHODS: Between 1995 and 2009, 105,908 patients were diagnosed with malignancy at Severance Hospital, Yonsei University Health System. Of these, 113 (0.1%) patients with MPC of three or more sites were registered, and 41 (36.3%) of these were GC-MPC. We retrospectively reviewed the clinical data and overall survival using the medical records of these 41 GC-MPC patients. We defined synchronous cancers as those occurring within 6 months of the first primary cancer, while metachronous cancers were defined as those occurring more than 6 months later. RESULTS: Patients with metachronous GC-MPC were more likely to be female (p=0.003) and young than patients with synchronous GC-MPC (p=0.013). The most common cancer sites for metachronous GC-MPC patients were the colorectum, thyroid, lung, kidney and breast, while those for synchronous GC-MPC were the head and neck, esophagus, lung, and kidney. Metachronous GC-MPC demonstrated significantly better overall survival than synchronous GC-MPC, with median overall survival durations of 4.7 and 14.8 years, respectively, and 10-year overall survival rates of 48.2% and 80.7%, respectively (p<0.001). CONCLUSION: Multiplicity of primary malignancies itself does not seem to indicate a poor prognosis. The early detection of additional primary malignancies will enable proper management with curative intent.

ABSTRACT

PURPOSE: Ezrin is a membrane cytoskeletal linker protein and it is known to be associated with metastasis of primary osteosarcoma. The aim of this study is to determine the relationship between an ezrin expression and several key clinical parameters and to elucidate its potential prognostic value for patients with osteosarcoma. MATERIALS AND METHODS: Seventy patients with histologically confirmed osteosarcoma and who had no distant metastasis were enrolled between 1995 and 2005 at Yonsei Cancer Center, Severance Hospital, Korea. The clinical parameters were retrospectively reviewed and immunohistochemical staining (IHC) for ezrin was performed using the surgically resected specimens. RESULTS: Of the 70 tumor specimens, 39 (55.7%) revealed an ezrin expression. More of an osteoblastic histology and an elevated initial ALP level were observed in the ezrin positive patients than in the ezrin negative patients (p=0.008 and 0.001, respectively). The proportion of patients who favorably responded to neoadjuvant chemotherapy (> or =90% necrosis) was significantly higher in the group of ezrin positive patients than that in the group of ezrin negative patient (72.2% vs 45.2%, respectively, p=0.024). The ezrin positive patients showed more frequent recurrence than did the ezrin negative patients (64.1% vs 35.5%, respectively, p=0.017). The patients with an ezrin expression also demonstrated poorer survival than did those patients without ezrin expression (5-year EFS: 31.7% vs 61.3%, respectively, p=0.023, 5-year OS: 53.4% vs 71.0%, respectively, p=0.022). When comparing EFS according to both an ezrin expression and chemoresponsiveness, there were trends that the ezrin negative/chemoresponsive group showed the best 5-year EFS (71.4%), followed by the ezrin negative/chemoresistant group (52.9%), the ezrin positive/chemoresponsive group (38.1%) and the ezrin positive/chemoresistant group (13.6%). These trends were statistically significant (p=0.036). CONCLUSION: The expression of ezrin by IHC staining was found in 55.7% of the patients with metastasis-free osteosarcoma. Immunoreactivity to ezrin is a negative prognostic factor for survival for the patients suffering with osteosarcoma. Identifying an ezrin expression might offer a valuable piece of information when treating patients with primary osteosarcoma.

ABSTRACT

PURPOSE: A colorectal carcinoma is the fourth most common malignancy in the world. Unfortunately, only approximately 20% of the liver metastases are resectable at the initial presentation. Neoadjuvant chemotherapy has been used for downsizing in unresectable disease. In addition, the use of newer biologic agents, such as cetuximab and bevacizumab, has much improved responses in patients with unresectable colorectal liver metastases. The aim of this study was to report on patients who had received a curative resection following neoadjuvant chemotherapy including a molecularly targeted agent for unresectable colorectal liver metastases. METHODS: Following the neoadjuvant chemotherapy using cetuximab plus FOLFIRI (irinotecan and infused fluorouracil plus leucovorin) or bevacizumab plus FOLFOX (oxaliplatin and infused fluorouracil plus leucovorin), 10 patients with initially unresectable colorectal liver metastases underwent a curative surgical resection between September 2005 and June 2007. RESULTS: One patient underwent a right lobectomy, three patients a segmentectomy and five a wedge resection with or without radiofrequency ablation. With a median postoperative follow-up of 14 months (range, 1 to 22 months), five recurrences (50%) occurred. The common toxic effects were grade 2/3 skin toxicity (60%), grade 4 hematologic toxicity (20%), grade 3 gastrointestinal toxicity (10%), and grade 3 neurologic toxicity (10%). CONCLUSIONS: Our preliminary data suggests that neoadjuvant chemotherapy including a molecularly targeted agent may improve resectability in patients with initially unresectable colorectal liver metastases although a high recurrence rate exists. Randomized prospective studies comparing neoadjuvant chemotherapy including a targeted agent in cases of unresectable colorectal liver metastases are warranted.

ABSTRACT

Surgical resection of colorectal cancer metastasis to the liver results in a 5-year survival rate of around 40%. Liver metastasis from other cancers such as neuroendocrine carcinoma and genitourinary tumors are also treated effectively with combined liver resection. However, hepatic metastasectomy for liver tumor from gastric cancer hasn't been considered as a standard treatment, and the benefit for this treatment has not been established. We report here on two cases of gastrectomy and combined liver resection for synchronous liver metastasis without any evidence of other metastatic lesions, and these two patients have survived for more than 7 years without evidence of disease recurrence. In conclusion, for patients with hepatic metastasis from gastric cancer, combined surgical resection of the liver metastasis should be considered as a treatment option when metastasis to other sites can be excluded.

ABSTRACT

PURPOSE: This study examined the effects of spirituality promoting intervention for the stomach and colon cancer patients. METHOD: A quasi-experimental design was used. Data collection was carried out from April 2004 to June, 2004 at a cancer center in Korea. The intervention included pray, meditation, group education and discussion for coping with cancer. The experimental group were received a 1-hour intervention per week for 6 weeks, while the control group received usual care. Data collection was done at pre and post intervention. The degree of spirituality was measured by the Korean version of WHOQOL-SRPB pilot test(WHO Quality of Life-Spirituality, Religiousness and Personal Beliefs pilot test) Module, and social support was measured using scores on a PRQ 85(Personal Resources Questionnaire). Fighting spirit was measured by the scores of MAC(Mental Adjustment to Cancer) scale. RESULTS: The experimental group showed significant increase in the scores of social support and fighting spirit compared to those in the control group after the intervention. There were no significant changes in terms of the spirituality score compared to the baseline score in the experimental group and the control group. CONCLUSION: This intervention appeared to be effective in increasing social support and fighting spirit, which considered to be very helpful in cancer adjustment.

ABSTRACT

Hodgkin's disease (HD) is a hematologic malignancy which shows common features regardless of race, but racial differences may be considered with certain clinical characteritcs. HD in Korea shows somewhat different characteristics when compared to cases in Western countries. We evaluated the clinical and histopathologic characteristics of HD, the outcomes of various chemotherapy regimens, and prognostic factors of HD in Korea. One hundred and five patients with initial histopathologic diagnosis of Hodgkin's disease were retrospectively reviewed 20 years after diagnosis at Yonsei University College of Medicine. Nodular sclerosis was the most common histopathogic subtype (41%) and mixed cellularity was nearly as common (40%). The overall complete remission rate (CR) was 87.6%. The disease-free survival (DFS) and overall survival (OS) rate were 79.2% and 84.8% at 5-years, 70% and 79.2% at 10- and 20-years. There were no significant differences in CR rate and DFS, but OS rates were significantly higher in m-BACOP and ABVD regimen. Univariate analysis revealed that age, B-symptom, ECOG scale, Ann Arbor stage, international prognostic index, and serum beta2-microglobulin level were significant prognostic factors for both DFS and OS. Multivariate analysis demonstrated that age, B symptoms, and ECOG scale were significant prognostic factors for OS only. In conclusion, the survival rates of HD patients in our center were superior to those of previous reports in Korea and Western countries. Considering the higher OS rate and decreased incidence of side effects, the ABVD regimen may be recommended for the initial treatment of Hodgkin's disease.

ABSTRACT

Tailgut cysts (TGCs) are rare congenital cysts that occur in the retrorectal or presacral spaces. Although most tailgut cysts have been reported as benign, there have been at least 9 cases associated with malignant change. We report herein on an unusual case of a 40-year-old woman with a carcinoembryonic antigen (CEA) -producing adenocarcinoma arising within a TGC who underwent surgical resection and local radiation therapy. Despite the complete resection, metastatic adenocarcinoma developed five months after surgery. CEA-producing adenocarcinoma from a TGC is extremely rare and only two cases, including this case, have been reported in the English medical literature. Besides CEA, the serum levels of CA 19-9 became markedly elevated in this patient. Given that the serum CEA level decreased to the normal range after complete resection of tumor and that the tumor recurrence was associated with a rebound of the CEA serum level, our case shows that serial measurements of serum CEA can be used for treatment planning and for assessing the patient's treatment response for this rare disease.

ABSTRACT

OBJECTIVE: Prenatal cytogenetic diagnosis is limited to metaphase karyotype analysis of cultured cells obtained by amniocentesis or chorionic villus sampling. Moreover, genome wide analysis cannot be performed by FISH analysis using specific probe. Array comparative genomic hybridization (CGH) offers a number of advantages over conventional cytogenetic analysis and FISH. Microarray CGH can be highly comprehensive, amenable to very high resolution, sensitive and fast. The objective of this study was to determine the clinical use of cDNA microarray CGH for detection of fetal aneuploidy. METHODS: 21 amniotic fluid samples and 6 chorionic villi samples were obtained from 27 pregnant women in 9-19 gestational weeks. Genomic DNA was extracted from each sample and amplified. For cDNA microarray CGH analysis, test DNA sample and reference DNA sample were labeled with Cy3-dUTP and Cy5-dUTP, respectively. Each sample of labeled test and reference DNA was hybridized to microarray. The result was analysed with axon scanner and compared with cytogenetic analysis and FISH. RESULTS: In 27 cases, 3 cases with trisomy 21 and 1 case with trisomy 18 had increased hybridization signals on chromosome 21 and chromosome 18. One case with 45,X had decreased signals on chromosome X. One case with 46,X,i(Xq) had decreased signal on short arm of chromosome X and increased signal on long arm. And one case with 47,XYY had two fold increased signal on Y chromosome. cDNA microarray based CGH correctly identified fetal aneuploidy in all of the 7 cases with aneuploid fetuses. CONCLUSION: Prenatal genetic diagnosis by cDNA microarray-based CGH is an useful, innovative, rapid and accurate method. It is promising technique allowing rapid screening for whole chromosomal changes including aneuploidy, and may augment standard karyotyping techniques for prenatal genetic diagnosis by providing additional molecular information. This method may aid the discovery and description of minor genetic aberration, potentially enhancing future prenatal genetic diagnostic application.

ABSTRACT

BACKGROUND: The primary mediastinal lymphoma (PML) is defined as the non-Hodgkin's lymphoma that presents primarily within the mediastinum, and primary mediastinal diffuse large B cell lymphoma (PMLBL) is defined as primary mediastinal lymphoma of which histology shows diffuse large B cell lymphoma. There is no available clinical study yet about the clinical characteristics and treatment outcome of PMLBL in Korea. Here the authors report our experience of 21 cases of PML including 11 cases of PMLBL. METHODS: The authors reviewed retrospectively medical records of 21 cases with PML from January 1992 to January 2003, and analyzed clinical characteristics, response to induction therapy, and survival. The authors subsequently performed subset analysis in 11 cases with PMLBL. Median follow-up period was 16 months (range, 4~80 months). RESULTS: Male to female ratio was 8:13 and the median age of 21 PML cases was 33.5 years. Of 21 PML cases, histology of most cases was diffuse large B cell lymphoma (11/21) and lymphoblastic lymphoma (8/21). Cell lineage was B cell in 13 cases (61.9%). Thirteen cases (62.0%) were in stage I and II. Initial induction therapy was chemotherapy alone in 19 cases, combined chemoradiotherapy in 1 case and no treatment in remaining 1 case. Response rate to initial therapy was 70% in 20 PML cases (complete response [CR] 50%, partial response 20%) with CR of 50% in 10 PMLBL. Median progression-free survival and overall survival for 11 PMLBL cases were 11 months and 16 months, respectively. CONCLUSION: Incidence of PML showed slight predominance in female and in relatively young age with median age of less than 40 years. Most patients presented with a chief complaint of superior vena cava syndrome including dyspnea. The most common histology of PML was diffuse large B cell lymphoma. PMLBL represented low complete response rate to conventional chemotherapy, low progression-free and overall survival rates compared with peripheral diffuse large B cell lymphoma by historical review.

ABSTRACT

Percutaneous approaches, such as percutaneous ethanol injection and radiofrequency ablation, have been most widely used for hepatocellular carcinoma patients who were not eligible for surgery. New technologies to improve the efficacy are currently needed. 166Holmium is a neutron activated radionuclide, and has several beneficial radiophysical characteristics for internal radiation therapy. 166Holmium-Chitosan complex, in which chitosan is chelated with 166Holmium, was developed as a radiopharmaceutical for cancer therapy. We have conducted a pilot study to evaluate the clinical efficacy of transarterial administration of 166Holmium-Chitosan complex in patients with a single and small (< 3 cm) hepatocellular carcinoma. 166Holmium-Chitosan complex, at a dose of 20 mCi per cm of tumor mass-diameter, was administered through the artery that directly fed the tumor. Twelve patients were treated with a median follow-up duration of 26 (range: 12-61) months. The tumor diameter ranged between 1.5 and 2.5 cm. Ten patients (83%) had complete response and two (17%) had partial response. The median complete response duration was not reached. The median AFP level declined from 83.8 to 8.3 ng/mL within 2 months after treatment. No grade III/IV toxicity was observed. Grade I and II toxicities were observed in four patients (2 abdominal pain, 1 fever, and 1 AST/ALT elevation). No toxic death occurred. This preliminary study shows a promising and durable complete response rate with an acceptable safety profile. Further studies with greater accrual of patients are warranted.

ABSTRACT

PURPOSE: For patients with Dukes' stage B and C rectal cancer, surgery followed by adjuvant chemoradiotherapy is considered to be the standard treatment. However, the drugs used in combination with 5-fluorouracil (5-FU), the method of administration, duration of adjuvant therapy and the frequencies of administration presently remain controversial topics. We investigated (1) the efficacy and safety of adjuvant radiotherapy and 5-FU/leucovorin (LV) chemotherapy for patients who had undergone curative resection and (2) the effect of dose related factors of 5-FU on survival. MATERIALS AND METHODS: 130 rectal cancer patients with Dukes' B or C stage disease who were treated with curative resection were evaluated. The adjuvant therapy consisted of two cycles of 5-FU/LV chemotherapy followed by pelvic radiotherapy with chemotherapy, and then 4~10 more cycles of the same chemotherapy regimen were delivered based on the disease stage. The cumulative dose of 5-FU per body square meter (BSA), actual dose intensity and relative dose intensity were obtained. The patients were divided into two groups according to the median value of each factor, and the patients' survival rates were compared. RESULTS: With a median follow-up duration of 52 months, the 5-year disease-free survival and overall survival rates of 130 patients were 57% and 73%, respectively. Loco- regional failure occurred in 17 (13%) of the 130 patients, and the distant failure rate was 27% (35/130). The chemotherapy related morbidity was minimal, and there was no mortality for these patients. The cumulative dose of 5-FU/ BSA had a significant effect on the 5-year overall survival for Dukes' C rectal cancer patients (p=0.03). Multivariate analysis demonstrated that only the performance status affected the 5-year overall survival (p=0.003). CONCLUSION: An adjuvant therapy of radiotherapy and 5-FU/LV chemotherapy is effective and tolerable for Dukes' B and C rectal cancer patients. A rospective, multicenter, randomized study to evaluate the effects of the cumulative dose of 5-FU/BSA on survival is required.

ABSTRACT

PURPOSE: This study was performed to estimate the response rate and toxicity of a combination chemotherapy, which included infusional 5-Fluorouracil, Leucovorin and Docetaxel in the treatment of patients with an advanced gastric carcinoma. MATERIALS AND METHODS: Twenty two advanced gastric cancer patients, with a bidimensionally measurable or an evaluable disease, were enrolled in this study. The patients received a 5-fluorouracil 1, 000 mg/m2 intravenous (IV) 24 hour infusion (Day 1~3), leucovorin 20 mg/m2 (Day 1~3) and docetaxel 75 mg/m2 intravenously (Day 2) every 3 weeks. RESULTS: The overall response rate was 45.0%. The median duration of response was 10.0 weeks (range: 4~24), the median time to response was 8 weeks (range: 8~20) the median time to progression was 30.0 weeks (95% CI: 16.3~43.2) and the median overall survival duration was 36.0 weeks (95% CI: 1.7~70.2). The median cumulative dose of 5-fluorouracil were 316.2 mg/m2/week and docetaxel was 23.9 mg/m2/week. WHO grade III, IV neutropenia, thromocytopenia and anemia occurred in 50.0%, 4.5% and 4.5% of patients, respectively. There were no occurrence of WHO grade III and IV nausea, vomiting, mucositis, conspitation, diarrhea, or neurotoxicity. CONCLUSION: This chemotherapy regimen, including infusional 5-fluorouracil, leucovorin and docetaxel was an active agent against advanced gastric cancer patients, especially for previous chemotherapy naive patients.

ABSTRACT

Nephrotic syndrome is a rare manifestation of malignancy associated with paraneoplastic syndrome. Paraneoplastic nephrotic syndrome has been reported in various malignancies: malignant lymphoma, colon cancer, lung cancer and prostate cancer. However, an ovarian carcinoma associated with nephrotic syndrome has rarely been reported. Only six cases of ovarian carcinoma associated paraneoplastic nephrotic syndrome has been reported worldwide, but no cases have been reported in Korea. Here, we report a case of paraneoplastic nephrotic syndrome in a patient with an ovarian carcinoma. The patient presented with ascites, proteinuria and hypoalbuminemia. An initial computed tomography (CT) scan and ultrasonography evaluations showed no specific findings suggestive of an ovarian tumor. Despite treatment for nephrotic syndrome, the symptoms became more aggravated. There after, follow up evaluation at Yonsei University Medical Center, including serum CA 125, pelvis MRI and peritoneal fluid examination were performed. On the pelvis MRI, a left ovarian mass was detected with an ascitic fluid collection. The serum CA 125 level was elevated to 2211 U/ml. The peritoneal fluid cytological examination showed malignant cells suggestive of an ovarian carcinoma. Combination chemotherapies including paclitaxel plus carboplatin, topotecan plus gemcitabine and oxaliplatin plus capecitabine were administered to the patient, and complete remission was achieved on image and tumor marker studies. There was complete recovery from the nephrotic syndrome with no evidence of ascites and proteinuria. These findings suggest that nephrotic syndrome caused by paraneoplastic syndrome can be resolved only after the complete control of the underlying malignancy.

ABSTRACT

PURPOSE: The aim of this study was to examine the associations between depression, anxiety, hostility and fighting spirit among patients with stomach, colorectal or breast cancer. MATERIALS AND METHODS: 223 patients, diagnosed as with stomach, colorectal or breast cancer, undergoing chemotherapy or follow up care, were the subjects of the study. The study design was cross-sectional at the time of the survey. The degrees of depression, anxiety and hostility of the patients were assessed by the SCL-90-R scores, and the fighting spirit was measured by the Mental Adjustment to Cancer (MAC) scale score. RESULTS: The scores of anxiety and hostility of the patients at younger age were higher than those at older age (p<0.01). The patients with metastasis were more depressed than those without it (p<0.01). There was a negative association between depression and fighting spirit (p<0.001). CONCLUSION: The study showed the more depressed cancer patients had lower fighting spirit score, which was known to be one of the most active psychosocial contributors in adjusting to cancer and survival.

ABSTRACT

PURPOSE: A single institute trial of combination chemotherapy, with paclitaxel and cisplatin, in patients with metastatic breast cancer, having failed previous combination chemotherapy, was performed. MATERIALS AND METHODS: Patients were only eligible for this study if there disease had progressed, following treatment with previous chemotherapy, in either an adjuvant or a metastatic setting. Paclitaxel 175 mg/m2 was administered as a 3-hour continuous infusion on day 1, and cisplatin 80 mg/m2 was administered for 2 hours on day 2, with adequate hydration. This was repeated every 3 weeks, and continued until one of the following events occurred: disease progression, unacceptable adverse effect or treatment refusal by the patient. Intercurrent palliative radiotherapy, or concurrent hormonal therapy, was permitted, depending on each patient's status. All the endpoints were evaluated under the principle of intention to treat analysis. RESULTS: A total of 24 patients entered the study, and 18 had at least one measurable lesion, but 6 did not. The objective response rate of the 18 patients was 50%(9/18). Two were complete responses and seven showed partial responses. The median response duration, progression free and overall survival were 5.3 months (range, 4~18), 6 months (95% CI, 5~7) and 12 months (95% CI, 7~17), respectively. 67% of the planned dose was administered. Out of a total 135 cycles administered, about 20% of cycles showed grade 3 or 4 leukopenia and 7% showed grade 3 thrombocytopenia. Two patients suffered from pneumonia, and one experienced neutropenic fever. Mucositis, greater than grade 3, existed in three cases. No treatment related deaths were reported. CONCLUSION: The combination chemotherapy, with paclitaxel and cisplatin, was active in the treatment of metastatic breast cancer patients having failed previous chemotherapy.
