Bilateral Rhegmatogenous Retinal Detachments after Systemic Pazopanib Treatment

PURPOSE: A case of bilateral rhegmatogenous retinal detachment is reported after pazopanib treatment of a patient with breast angiosarcoma. CASE SUMMARY: A 53-year-old female presented with bleeding in a right breast mass prior to an emergency room visit. She was diagnosed with metastatic breast angiosarcoma after a breast mass biopsy. She was treated with paclitaxel and radiation therapy. Systemic pazopanib treatment was added to treat lung metastasis. After 3 weeks, she felt sudden floaters in her right eye. In her fundus examination, there was vitreous hemorrhage, but no retinal detachment was noted. Five weeks later, she visited the clinic for a bilateral temporal visual field defect. A fundus examination showed bilateral retinal detachments with superonasal retinal tears. Both the patient and her family did not want surgery for her systemic condition because of her terminal cancer. CONCLUSIONS: Retinal detachment has been reported as a rare complication after systemic pazopanib treatment, but there has been no previous report in the Republic of Korea, therefore this is the first case of bilateral retinal detachments after systemic pazopanib treatment.

Weekly Gemcitabine and Docetaxel in Refractory Soft Tissue Sarcoma: A Retrospective Analysis / Journal of the Korean Cancer Association, 대한암학회지

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.

A Case of Endobronchial Lipoma Causing Right Middle and Lower Lobes Collapse and Bronchiolitis Obliterans-organizing Pneumonia / 결핵및호흡기질환

Lipoma is a common neoplasm in soft tissues. However, an intrapulmonary lipoma is a rare benign tumor. Patients with a bronchial lipoma might have a malignant potential related to their smoking history due to the case reports of lung cancer accompanied with lipoma. Endobronchial lipoma can cause irreversible parenchymal lung damage if not diagnosed and treated early. Therefore, it should initially be treated by fiberoptic bronchoscopy or surgery depending on the status of distal parenchymal lung damage. Bronchiolitis obliterans with organizing pneumonia (BOOP) is a pathological syndrome that is defined by the presence of buds of granulation tissue consisting of fibroblasts and collagen within the lumen of the distal air spaces. BOOP is caused by drug intoxication, connective tissue disease, infection, obstructive pneumonia, tumors, or an unknown etiology. We encountered a 58 year-old male patient with endobronchial lipoma, causing the collapse of the right middle and lower lobes, and BOOP due to obstructive pneumonia.

The Clinical Characteristics and Outcome of Breast Cancer Patients Older than 70 Years / 한국유방암학회지

PURPOSE: There is no concensus on the type of therapy useful for elderly cancer patients. Since 2000, Korea has become an elderly society. This study aims to assess clinical characteristics of elderly breast cancer women, and to evaluate determinants and effects of treatment choice for breast cancer prognosis among elderly patients. METHODS: We reviewed the clinical reports of 123 breast cancer patients aged > or =70 yr recorded at the Asan Medical Center Breast Cancer Registry between 1992 and 2002. Patient and tumor chariteristics, comorbidity, surgical method, adjuvant therapy and cause of death were taken into consideration. Survival analysis was determined according to the treatment method. RESULTS: The median time to diagnosis was 33.6 months. Only 9 patients (5.1%) were diagnosed in the screening program. A modified radical mastectomy was performed for 74 patients (60.1%), Breast conserving surgery was performed for 26 patients (24.7%), and there was no further curative therapy for 12 patients (9.7%). 32 patients (38.1%) had axillary lymph node metastasis. The median follow-up duration was 43.1 months; the overall survival rate was 71.8%, and the disease free survival rate was 65.4%. Breast cancer related mortality was 62.8%. CONCLUSION: Delayed diagnosis and infrequent screening were frequent among elderly patients. Cancer related morbidity was less than general breast cancer patients. Treatment needs to be adapted to the general health status of the patient and comorbid conditions, but has to offer the best chance of cure, regardless of age.

Comparison of Early Postoperative Axillary Morbidity Following the Sentinel Lymph Node Biopsy or Axillary Lymph Node Dissection / 한국유방암학회지

PURPOSE: Sentinel lymph node biopsy (SLNB) is a relatively accurate diagnostic method for determining the presence of axillary lymph node metastasis (ALND). SLNB reduces the need for axillary lymph node dissection, thereby decreasing the postoperative axillary morbidity. The present study compared the postoperative axillary morbidity rates during early postoperative days for patients undergoing either SLNB or conventional ALND. METHODS: We conducted a prospective case-control study of breast cancer patients. The degree of axillary morbidity was compared between 28 SLNB patients (Group I) and 38 ALND patients (Group II). RESULTS: The SLNB group showed decreased arm swelling and restriction of their shoulder motion in comparison with the conventional axillary dissection group (p<0.05). SLNB and additional lymph node sampling did not result in any additional morbidity. CONCLUSION: SLNB or lymph node sampling was associated with less axillary morbidity like arm edema, limitation of motion than was conventional ALND. The rate of postoperative axillary morbidity did not differ following lymph node sampling and SLNB. SLNB may be an effective method for diagnosing of axillary lymph node metastasis with decreasing the postoperative axillary morbidity

Experience of Ovarian Function Suppression Therapy: Endocrine Response Preand Perimenopausal Korean Breast Cancer Patients in the Adjuvant Setting / 한국유방암학회지

PURPOSE: Published Early Breast Cancer Trialists' Collaborative Group overview results have been the beneficial effects of tamoxifen and ovarian ablation for pre and perimenopausal women with node negative breast cancer. Chemotherapy and Luteinizing Hormone Releasing Hormone (LHRH) agonists (medical ovarian ablation) have been shown to be effective adjuvant therapies for early stage breast cancer in several clinical trials however, the efficacy and tolerance of LHRH agonists in Korean breast cancer patients has not been evaluated. METHODS: Three thousand one hundred fifty breast cancer patients were treated at Asan Medical Center between January 2003 and December 2005. We selected 185 patients with node negative early breast cancer who were endocrine responsive (more than intermediate intensity), with a tumor size more than 1 cm, and who were reluctant to undergo chemotherapy due to the side effects. They received LHRH agonists (Zoladex(R) 3.6 mg) every 28 days with tamoxifen for two years. We prospectively evaluated mammography, chest PA, and physical examination every six months and evaluated the side effects and quality of life. RESULTS: The mean age was 43.5 yr, and the mean tumor size was 1.62 cm. One hundred sixty-two patients had Stage I, and 23 Stage II disease. The incidence of severe menopausal symptoms was 24.1%, but these symptoms were reported to be "tolerable" during the two year follow-up. Quality of life and physical activity were essentially unchanged. The median follow-up duration was 18 months, and there was no local recurrence or distant metastases during the study. CONCLUSION: Adjuvant therapy with LHRH agonists is safe and tolerable, and may be an alternative to chemotherapy for pre-and perimenopausal women with hormone responsive early breast cancer who are reluctant to undergo chemotherpy.

Pulmonary Thromboembolism following Mastectomy with Immediate TRAM in the Patients with Breast Cancer : a Prospective Study / 한국유방암학회지

PURPOSE: : Skin-sparing mastectomy with immediate reconstruction provides psychological satisfaction and a good cosmetic effect for patients with breast cancer. However, this procedure takes longer operation time than mastectomy, and the risk of pulmonary thromboembolism (PTE) and deep vein thrombosis may be increased. The purpose of this study was to evaluate the incidence of PTE. METHODS: Between January and May in 2005, 54 breast cancer patients who underwent skin-sparing mastectomy with immediate transverse rectus abdominalis myocutaneous flap (TRAM) at Asan Medical Center were prospectively investigated according to the clinicopathologic data. Patients were placed in compression stockings on the day of operation, and lung perfusion, inhalation scans,and serum D-dimer assays were performed on the first three postoperative days. If findings were suspicious, we performed embolism computed tomography. We compared patient age, body mass index (BMI), clinical risk factors, operative findings, pathologic results, and the clinical course between PTE patients and non-PTE patients. RESULTS: There were 9 cases of intermediate probability and 6 cases of high probability for PTE according to lung perfusion and inhalation scans, and they underwent embolism CT. Eleven patients (20.4%) were diagnosed with embolism CT or with lung perfusion and inhalation scans;2 patients were symptomatic and 9 patients were asymptomatic. There was significant difference between PTE and non-PTE patients for age, but none for BMI, clinical risk factors, operation time, serum D-dimer, or stage. CONCLUSION: The incidence of PTE after mastectomy with immediate TRAM is relatively high, and a strategy for the prevention and treatment of PTE is required. Although age is a risk factor for PTE on this study, future studies are needed to determine the risk factors for and to confirm proper treatment and prevention of PTE.

Symptomatic Pulmonary Thromboembolism following Skin-sparing Mastectomy with Immediate TRAM Reconstruction in Breast Cancer Patients

PURPOSE: A skin-sparing mastectomy (SSM) with immediate reconstruction can give psychological and cosmetic benefits to patients requiring a mastectomy, but a risk of pulmonary thromboembolism (PTE) also exists due to longer operative time. The purpose of this study was to evaluate the clinical characteristics of symptomatic PTE following a SSM with immediate reconstruction. METHODS: Of 216 breast cancer patients underwent a SSM with immediate reconstruction at the Asan Medical Center, between December 2003 and July 2005, 7 in whom postoperative symptomatic PTE developed were included in this study. The ventilation/perfusion scan, embolism CT and serum D-dimer level were checked for those suspected of PTE. RESULTS: The prevalence of symptomatic PTE was 3.2% (7/216). Mean patient age and BMI were 41 years and 24.9 kg/m2, respectively. All patients had undergone TRAM reconstruction, with mean operative time of 562.1 minutes. Postoperative bleeding developed in 4 cases. The pathological stages included 0, I and IIA, which were observed in 1, 4 and 2 cases, respectively. Most common symptom of PTE was dyspnea, which developed in all patients on the second or third postoperative day; followed by chest discomfort and tachypnea. The ventilation/perfusion scans showed 6 with high probabilities. All seven patients were diagnosed as PTE on embolism CT. One patient had DVT on the lower extremities. The most common site of PTE was the superior lobar artery and the segmental branches of the right pulmonary artery. All patients recovered, or were recovering, after the LMWH and warfarin treatment. CONCLUSION: This study has shown that SSM with immediate reconstruction possesses a considerable risk of postoperative PTE. Further study on preoperative prophylaxis and the risk factors is warranted to prevent PTE.

Surgical Treatment of Locoregional Recurrence in Breast Cancer / 한국유방암학회지

PURPOSE: The locoregional recurrence (LRR) in breast cancer, without distant metastasis has traditionally been regarded as a predictor of subsequent distant metastasis. This study was designed to attain the survival rate, disease progress in patients with a LRR only and to approve a locoregional treatment able to increase the survival in specific locoregional recurrent breast cancer. METHODS: The records of 223 patients with LRR, after initial treatment at the Asan Medical Center, between 1989 and 2003, were retrospectively reviewed. The patients were classified into the LRR only and simultaneous distant metastasis groups with the LRR group subdivided into the operable and inoperable groups. The data were analyzed using SPSS 11.0. RESULTS: There were 152 and 71 patients in the LRR only and simultaneous distant metastasis groups respectively: 105 patients in the LRR only group were operable cases. The 5-year survival rate of LRR was 42.5%, but this was 50.1% in the LRR only group. The 5-year survival rates following a recurrence in the operable and inoperable groups were 66.2% and 21.1%. On multivariate analysis, age at the primary surgery, tumor size, hormone receptor status and DFI were independent prognostic factors for survival. The operable group indicated less tumor size at the primary surgery, less lymph node metastasis and more chest wall or axillary lymph node recurrences, compared to the inoperable group. CONCLUSION: In some of the LRR only cases, the survival rate was relatively good, especially in the operable group. Age at the primary surgery, tumor size, hormone receptor status and DFI were independent prognostic factors for survival. Surgical treatment could be resulted in good responses to the LRR patients with early stage or chest wall or axillary recurrences.

Recurrence and Survival Analysis in Skin-Sparing Mastectomy with Immediate Reconstruction Compared with Conventional Mastectomy / 한국유방암학회지

PURPOSE: A skin-sparing mastectomy (SSM), followed by immediate reconstruction, which has aesthetic advantages, is being increasingly used to treat many early breast carcinomas; however, there are few data regarding the outcome and safety of this procedure. The objective of this study was to evaluate the safety of utilizing a SSM with immediate reconstruction compared with the outcome of a conventional mastectomy. METHODS: A retrospective review was performed on 169 patients who underwent a SSM with immediate reconstruction, and 2102 patients who received a conventional mastectomy between January 1996 and December 2002, at the Asan Medical Center. The patient and tumor characteristics, as well as the types of reconstruction, incidences of recurrence and survival rates were examined. RESULTS: The mean age of the SSM group was younger (39 vs. 47 years, p < 0.001), and the mean tumor size smaller than those of the mastectomy group (2.6 vs. 3.2cm, p = 0.002). Lymph node involvement was present in 39.6% and 48.4% of the SSM and mastectomy groups, respectively (p = 0.24). The proportion at early stages (0 and 1) in the SSM group was higher than those in the mastectomy group (50.9 vs. 30.7%, p < 0.001). In the high-risk patients, postoperative radiation was administered to 24.1 and 54.9% of the SSM and mastectomy group, respectively (p = 0.002). With a median follow-up of 41 months, the recurrence rates for the SSM and mastectomy groups were 11.8 (20 of 169 patients) and 14.4% (303 of 2102 patients), respectively (p = 0.22). There were no differences in the locoregional and distant recurrences between the two groups. The 5-year disease free survivals for the SSM and mastectomy groups were 81.9 and 81.7%, respectively (p = 0.71). The 5-year overall survivals for the SSM and mastectomy groups were 91.7 and 88,8%, respectively (p = 0.13). In a univariate analysis, the factors associated with a recurrence and the survival rates were the tumor stage and a lymph node positive state. CONCLUSION: No significant differences were found in the recurrence and survival rates of the SSM group, with immediate reconstruction, compared to those of the mastectomy only group. A skin-sparing mastectomy, with immediate reconstruction, which has greater aesthetic benefits, appeared to be an oncologically safe treatment option for breast carcinomas.

Risk Factors for Postoperative Complications of Gastric Cancer Patients

PURPOSE: The surgical techniques and postoperative care for gastric cancer have significantly improved in recent years. However, the incidence of several complications that can result in relatively increased mortality remains high. The aim of this study was to evaluate the risk factors associated with postoperative morbidity in surgery for gastric cancer. METHODS: Four hundreds and one consecutive patients, who underwent surgery for gastric cancer at National Medical Center between January 1994 and December 2002, were reviewed. RESULTS: The overall morbidity and mortality rates were 10.2 and 1.5%, respectively. A univariate analysis of multiple clinical variables revealed that age, leukocyte counts, albumin, protein, comorbid disease, combined resection, operation time, blood loss, operation type, curability, extent of lymph node dissection and stage were significantly associated with morbidity. However, a multivariate analysis showed that comorbid diseases and low curability were independent factors associated with morbidity (P<0.05). CONCLUSION: In patients with comorbid diseases and a noncurative resection, the complication rate was significantly higher. More attention should be paid to the early diagnosis, preoperative evaluation and intraoperative caution of patients with preoperative risk factors.

Risk Factors Associated with Mortality in Emergency Surgery for Perforated Peptic Ulcer

PURPOSE: Despite modern medication, peptic ulcer, patients often require emergency surgery for complications of peptic ulcer disease, and the mortality due to a perforated peptic ulcer still remains high. This retrospective study was conducted to evaluate the risk factors associated with mortality in patients undergoing surgery for a perforated peptic ulcer. METHODS: Two hundred and four consecutive patients (mean age: 45.8 years; range: 15~0 years) who underwent emergency surgery for a perforated peptic ulcer at the National Medical Center, between January 1991 and December 2000, were reviewed. RESULTS: The overall mortality rate was 5.9%. A univariate analysis of multiple clinical variables revealed old age (> or =65 years), duration of symptoms (> or =24 hours), NSAIDs or steroid use, comorbid disease, shock on admission, low hemoglobin ( or =20 mg%), higher creatinine (> or =1.5 mg%), gastric ulcer and simple closure to be significantly associated with mortality. However, a multivariate analysis showed that shock on admission, comorbid disease and old age (> or =65 years) were independent predictors of mortality. CONCLUSION: Shock on admission, comorbid disease and old age should be considered as significant prognostic factors of emergency surgery for a perforated peptic ulcer, and a comorbid disease and age as non modifiable factors. For that reason, prompt resuscitation is considered as the most effective therapy for reducing the mortality due to peptic ulcer perforation.

Simultaneous bilateral tubal pregnancies following in - vitro fertilization and embryo transfer / 대한산부인과학회잡지

Over the last 20 years, the frequency of multiple pregnancy has increased mainly because of the introduction of exogenous pituitary gonadotropins in the treatment of infertility. Since the advent of assisted reproductive technology, the concern about ectopic implantation of embryos has increased dramatically and it continues to be a major complication of in vitro fertilization and embryo transfer (IVF-ET). Bilateral tubal pregnancy is the least common type of ectopic implantation of two embryos. Of all extrauterine pregnancies, 1:725~1:1580 are bilateral1,2. Simultaneous tubal pregnancies have been reported in natural cycles, recently, after ovulation induction, in-vitro fertilization2,3. The high incidence of ectopic pregnancy associated with IVF-ET continues to be a problem and frequencies of between 2.4 and 12.4% have been only a few reports of simultaneous bilateral tubal pregnancies following IVF-ET4. This paper describes a case of a simultaneous bilateral tubal pregnancy after IVF-ET in a 33 year old patient. The diagnosis was confirmed by diagnostic laparoscopy performed 25 days after embryo transfer(sixth week of gestation), which revealed bilateral tubal pregnancy. Bilateral salpingectomy was performed. With a review of the literature on this topic, diagnostic aspects and treatment options are discussed.
