RESUMO

Objectives: The objective of this study was to observe the influence of laparoscopic adenomyomectomy on perinatal outcomes. Materials and Methods: The retrospective cohort study included 43 pregnant cases with adenomyosis who did not undergo laparoscopic surgery before pregnancy (nonsurgery group; 26 cases) and did (surgery group; 17 cases). To evaluate the impact of surgery on perinatal outcomes, nine obstetric complications including preterm delivery, hypertensive disorder of pregnancy, placental malposition, oligohydramnios, gestational diabetes mellitus, uterine rupture, abruptio placentae, and postpartum hemorrhage were selected. One obstetric complication was counted as one point (Maximum 9 points for one person). The obstetrical morbidity was compared by adding up the number of relevant events (0-9) between the two groups. Apgar score, umbilical artery pH (UApH), neonatal intensive care unit (NICU) admission, and neonatal death were also examined. Results: The surgery group had a significantly lower prevalence of fetal growth restriction compared to the nonsurgery group (nonsurgery vs. surgery; 26.9%, 7/26 vs. 0%, 0/17: P = 0.031). No differences were found in the morbidity of the nine obstetric complications (19.2%, 45/234 vs. 13.7%, 21/153), gestational weeks (mean ± standard deviation, 37.2 ± 2.4 vs. 36.4 ± 3.2), birth weight (2573.6 ± 557.9 vs. 2555.4 ± 680.8 g), Apgar score (1, 5 min; 8.0 ± 0.7 vs. 7.7 ± 1.2, 8.9 ± 0.6 vs. 8.5 ± 1.8), UApH (7.28 ± 0.08 vs. 7.28 ± 0.06), NICU admission (26.9%, 7/26 vs. 41.2%, 7/17), and neonatal death (0%, 0%) between both groups. Conclusion: Laparoscopic adenomyomectomy may not increase obstetric complications, although attention must be paid to uterine rupture during pregnancy.

RESUMO

AIM: This study aimed to clarify the impact of coronavirus disease 2019 on gynecology practice in Japan, in particular, on surgeries for benign gynecological diseases. METHODS: An online questionnaire was distributed to 966 facilities in Japan, including core facilities, facilities participating in perinatal and gynecologic oncology registries, and facilities certified for training by the Japanese Society of Obstetrics and Gynecology Endoscopy. The number of surgeries performed was compared between 2019 and 2020, when the novel coronavirus disease was prevalent. RESULTS: Five hundred and eighty (58.2%) facilities responded. The total number of surgeries decreased from 129 648 in 2019 to 118 565 in 2020, by 8.5%, for all surgical procedures. However, there was a clear increase in the number of robotic surgeries performed in 2020 compared to that in 2019 for all populations. The number of total hysterectomies decreased markedly from 15 385 in 2019 to 12 531 in 2020, a fall of 10.1%. CONCLUSIONS: The number of surgeries for benign gynecological diseases decreased by 8.5% in 2020 compared to that in 2019. This value is among the lowest in the world.

RESUMO

To evaluate whether uterine endometrium microbiota (UEM) is associated with pregnancy outcome in women with recurrent pregnancy loss (RPL). This prospective cohort study enrolled 67 women who had a history of two or more RPL. They underwent endometrial biopsy at midluteal phase for UEM analyses with 16 S ribosomal RNA sequence. Four women with inappropriate specimens were excluded. Therefore, 63 women were followed up for more than 14 months; 44 became pregnant, while 19 did not. Thirty of the 44 pregnancies ended in live births, including 24 full-term and six preterm deliveries. Three pregnancies were ongoing, and the remaining 11 ended in miscarriages, including eight miscarriages with normal chromosome karyotype and three miscarriages with abnormal karyotype. Clinical characteristics and UEM associated with risks for non-pregnancy, miscarriage with normal karyotype, and preterm delivery in subsequent pregnancies were evaluated. Multivariable logistic regression analyses revealed that the number of previous miscarriages (odds ratio 42.2, 95 % CI 1.19-1490, p = 0.040) and relative dominance rate of Ureaplasma species (odds ratio 24.2, 95 % CI 1.55-377, p = 0.023) in UEM were independent risk factors for subsequent miscarriage with normal karyotype; and relative dominance rate of Ureaplasma species in UEM was a risk factor for preterm delivery (odds ratio 109, 95 % CI 1.07-1110, p = 0.047). This study demonstrated for the first time that increases in Ureaplasma species in UEM of women with RPL were risks of miscarriage with normal chromosome karyotype and preterm delivery in subsequent pregnancies. UEM analysis for women with RPL before pregnancy may identify microbiota associated with adverse pregnancy outcomes.

RESUMO

Purpose: It is unknown whether surgery for endometriosis or recurrence of endometriosis affects obstetric outcomes. Methods: A total of 208 pregnant women with a history of endometriosis were analyzed. Patients who had endometriomas >3 cm and no history of laparoscopic surgery for endometriosis were defined as non-surgery group (n = 60), while those who had a history of surgery for endometriosis (n = 148) were defined as surgery group. We investigated the obstetric outcomes in 208 patients according to with or without postoperative recurrence of endometriosis and the time from surgery to pregnancy. Results: Among 177 cases of on-going pregnancy, in surgery group, there were lower prevalence of placenta previa compared with non-surgery group (8.5% vs. 23.4%; p = 0.020). Subgroup analysis revealed a decreased prevalence of placenta previa in postoperative non-recurrence group (6.0%: p = 0.007) compared with non-surgery (23.4%) and postoperative recurrence group (28.6%). Placenta previa was more prevalent in the patients who got pregnant more than 2 years after surgery (20.0%) than the patients who got pregnant within 2 years (2.4%: p = 0.002). Multivariate analysis revealed that the surgery was associated with a reduction in placenta previa (OR: 0.32, 95% CI [0.11-0.90]; p = 0.032). Conclusions: Pregnancy within two years after laparoscopic surgery for endometriosis may reduce placenta previa.

RESUMO

This study aimed to investigate the long-term changes in awareness of and knowledge about mother-to-child infections across 6 years in Japan. A questionnaire survey was conducted at our facility from October 2012 to January 2018, and the study periods were divided into 4 phases comprising 16 months each. A multiple-choice questionnaire assessed participants' awareness of the following 13 pathogens of mother-to-child infections: cytomegalovirus (CMV), Toxoplasma gondii (T. gondii), hepatitis B virus, rubella virus, herpes simplex virus, parvovirus B19, hepatitis C virus, human immunodeficiency virus, human T cell leukemia virus type-1, measles virus, varicella-zoster virus, Chlamydia trachomatis, and Treponema pallidum. For the selected four pathogens (i.e., CMV, rubella virus, T. gondii, and parvovirus B19), the questionnaire also evaluated participants' knowledge of transmission routes, the most susceptible time of infection that could yield severe fetal disease during pregnancy, the maximum frequency of fetal infection in cases of maternal infection, and methods to prevent maternal infection. In total, 1433 pregnant Japanese women were included in this study. There was no secular change in awareness of the pathogens concerning mother-to-child infections over time, and we also clarified that the detailed knowledge of the four pathogens of typical mother-to-child infections did not improve. Since knowledge about methods to prevent maternal infection is still insufficient for all pathogens, further advocacy is required to prevent mother-to-child infections.

RESUMO

Maternal infection or inflammation causes abnormalities in brain development associated with subsequent cognitive impairment and in an increased susceptibility to schizophrenia and autism spectrum disorders. Maternal immune activation (MIA) and increases in serum cytokine levels mediates this association via effects on the fetal brain, and microglia can respond to maternal immune status, but consensus on how microglia may respond is lacking and no-one has yet examined if microglial process motility is impaired. In this study we investigated how MIA induced at two different gestational ages affected microglial properties at different developmental stages. Immune activation in mid-pregnancy increased IL-6 expression in embryonic microglia, but failed to cause any marked changes in morphology either at E18 or postnatally. In contrast MIA, particularly when induced earlier (at E12), caused sustained alterations in the patterns of microglial process motility and behavioral deficits. Our research has identified an important microglial property that is altered by MIA and which may contribute to the underlying pathophysiological mechanisms linking maternal immune status to subsequent risks for cognitive disease.

RESUMO

Primary peritoneal carcinosarcomas which arise from extragenital locations are extremely rare. Carinosarcomas contain both carcinomatous and sarcomatous elements and can be mainly detected in the female genital tract. We herein report a case of primary peritoneal carcinosarcoma diagnosed by laparoscopic surgery and treated with olaparib. A 62-year-old woman referred to our hospital due to abdominal distension. From imaging findings, we suspected advanced primary peritoneal carcinoma, and laparoscopic surgery was thereafter performed. The pathological diagnosis was carcinosarcoma, and the patient received chemotherapy with docetaxel and carboplatin. After three cycles of chemotherapy, the interval debulking surgery was attempted but resulted in suboptimal results. Because the bilateral ovaries were observed with a normal size and normal findings, we considered that the most likely diagnosis was primary peritoneal carcinosarcoma. After the additional chemotherapy and a 6-month observation period, the tumor relapsed. The patient received chemotherapy again, and the peritoneal carcinosarcoma was judged to be a platinum-sensitive tumor. Oral administration of olaparib was thus initiated. Although a dose reduction was needed due to anemia, olaparib was effective, and the patient could continue the drug for another 7 months. This is the first report of primary peritoneal carcinosarcoma treated with olaparib and shows that it could be a treatment option for platinum-sensitive tumors.

RESUMO

INTRODUCTION: Congenital cytomegalovirus infection (CCMVI) may result in neurodevelopmental impairments (NDIs) such as hearing loss, developmental delay, epilepsy, and cerebral palsy. We aimed to investigate the potential for brain magnetic resonance imaging (MRI) to predict NDI in patients with CCMVI. METHODS: We studied infants with CCMVI who were referred to our hospital from April 2010 to October 2018 and underwent a brain MRI within 3 months since birth. We screened for 6 classic presentations of CCMVI including ventriculomegaly, periventricular cysts, hippocampal dysplasia, cerebellar hypoplasia, migration disorders, and white matter abnormalities. Images were interpreted by a blinded pediatric radiologist. NDI was defined as having a developmental quotient <80, hearing dysfunction, blindness, or epilepsy requiring anti-epileptic drugs at approximately 18 months of corrected age. RESULTS: The study involved 42 infants with CCMVI (median gestational age 38 weeks, birthweight 2,516 g). At least one abnormal finding was detected in 28 (67%) infants. Abnormal findings consisted of 3 cerebellar hypoplasia (7%), 7 migration disorders (17%), 26 white matter abnormalities (62%), 12 periventricular cysts (28%), 1 hippocampal dysplasia (2%), and 20 ventriculomegaly (48%). Abnormal findings were significantly more prevalent in infants with clinical symptoms (21/24, 91%) than in those without (7/19, 37%, p < 0.01). For NDI prediction, having ≥2 of ventriculomegaly, periventricular cysts, and white matter abnormality produced the highest Youden index values (0.78). CONCLUSION: Infants with CCMVI with at least 2 of the abovementioned specific brain image abnormalities may be at high risk of developing NDI.

RESUMO

BACKGROUND: Both twin pregnancies with complete hydatidiform mole and coexisting normal fetus (CHMCF) and partial hydatidiform mole can be found in association with a live fetus and a placenta displaying a molar degeneration. Two cases of CHMCF using magnetic resonance imaging (MRI) for a diagnosis are reported. CASE: In the first, CHMCF was suspected at 12 weeks of gestation. At 18 weeks of gestation, the existence of molar placenta and a sac separating from fetus and normal placenta was clearly depicted on MRI. At 19 weeks of gestations, she had termination of pregnancy because of a development of gestational trophoblastic neoplasia (GTN) and started chemotherapy. In the second case, CHMCF was suspected at 14 weeks of gestation. MRI demonstrated the existence of molar placenta and a sac separating from fetus and normal placenta. She chose induced abortion and there was no evidence of GTN during the 1 year-follow up period. Pathological examination in both cases was consistent with a complete hydration mole and a coexisting normal female fetus. CONCLUSION: MRI was useful for an accurate diagnosis for CHMCF.

RESUMO

Intestinal epithelial cells (IECs) play a pivotal role in the maintenance of the integrity and barrier function of the intestinal epithelium. Dysfunctions of IECs are thought to participate in the disruption of the intestinal epithelial barrier, resulting in gastrointestinal diseases, such as colitis and colorectal cancer. Here we show that IEC-specific COOH-terminal Src kinase (Csk)-deficient mice (Csk CKO mice) manifested the increased susceptibility to dextran sodium sulfate (DSS)-induced colitis, a model of inflammatory bowel disease. DSS-treated Csk CKO mice also exhibited the significantly elevated intestinal permeability. Following DSS treatment, Csk CKO mice exhibited the higher proliferative activity of colonic epithelial cells and the increased number of apoptotic cells in the colon compared with that apparent for control mice. Moreover, the abundance of the tight junction protein occludin, which regulates cell-cell adhesion as well as epithelial permeability, was markedly reduced in the colon of DSS-treated Csk CKO mice. These results thus suggest that Csk in IECs plays important roles in the regulation of the intestinal epithelial barrier function and protection against colitis.

RESUMO

We aim to clarify the incidence of deep venous thrombosis (DVT) before treatment in women with ovarian cancer and identify risk factors for DVT.In this prospective study, 110 women underwent venous ultrasonography before cancer treatment and D-dimer levels were measured. We investigated factors predicting DVT by logistic regression.DVT was detected in 25 of 110 women (22.7%) and pulmonary thromboembolism was coexisted in 2 women (1.8%). A total of 21 women (84.4%) with DVT were asymptomatic. D-dimer levels in women with DVT (median, 10.9; range, <0.5-98.2 µg/mL) were significantly higher than those in women without DVT (2.0; <0.5-60.8 µg/mL; P < .01). When 10.9 µg/mL was used as a cutoff value for D-dimer levels to predict DVT, specificity, sensitivity, and positive and negative predictive values were 92.9%, 52.0%, 68.4%, and 86.8%, respectively. The multivariate analysis demonstrated that D-dimer level (odds ratio [OR], 19.7; 95% confidence interval [CI], 5.89-76.76) and clear cell histology (OR, 7.1; 95% CI, 2.12-25.67) were independent factors predicting DVT.Asymptomatic DVT occurred with great frequency before treatment in patients with ovarian cancer. High D-dimer level and clear cell pathology is associated with a higher DVT risk.

RESUMO

Background: Transformed follicular lymphoma (TFL, ZC3H12D) was identified as a candidate tumor suppressor gene that contributes to cell-cycle arrest through regulation of Rb phosphorylation, but the clinical impact of TFL is unknown. The goal of this study was to evaluate the prognostic significance of TFL expression in advanced endometrial cancer.Methods: Tissue samples were obtained from 103 patients with Federation Internationale des Gynaecologistes et Obstetristes stage III-IV endometrial cancer. Associations between TFL expression and outcomes were evaluated using the Kaplan-Meier method and multivariate Cox proportional hazards regression models.Results: There were 24 TFL-low cases (23.3%) and the 10-year progression-free survival (PFS) and overall survival (OS) in these cases were lower than those for patients with normal TFL expression in univariate analysis (PFS, P = 0.003; OS, P = 0.106). In multivariate analysis, TFL status was a significant predictor for PFS [HR = 2.76; 95% confidence interval (CI), 1.45-5.28; P = 0.002] and OS (HR = 1.94; 95% CI, 0.91-4.11; P = 0.085), adjusted for covariates. The TFL gene maps to human chromosome 6q25.1, where estrogen receptor alpha (ERα) gene ESR1 is also located. Lack of ERα expression is a poor prognostic factor in early endometrial cancer. Among 41 ERα-low patients, 10-year PFS was significantly lower in 15 TFL-low cases (univariate analysis, P = 0.055; multivariate analysis, HR = 4.70; 95% CI, 1.68-13.20; P = 0.003).Conclusions: We identified TFL as a strong independent prognostic factor, regardless of ERα status.Impact: An investigation of the mechanism underlying tumor suppression by TFL may lead to new therapies for patients with advanced endometrial cancer.

RESUMO

INTRODUCTION: Placenta previa (PP) is one of the most significant risk factors for adherent placenta (AP). The aim of this study was to evaluate the diagnostic efficacy of a novel scoring system for predicting AP in pregnant women with PP. METHODS: This prospective cohort study enrolled 175 women with PP. The placenta previa with adherent placenta score (PPAP score) is composed of 2 categories: (1) past history of cesarean section (CS), surgical abortion, and/or uterine surgery; and (2) ultrasonography and magnetic resonance imaging findings. Each category is graded as 0, 1, 2, or 4 points, yielding a total score between 0 and 24. When women with PP had PPAP score ≥8, they were considered to be at a high risk for AP and received placement of preoperative internal iliac artery occlusion balloon catheters. If they were found to have AP during CS, they underwent hysterectomy or placenta removal using advanced bipolar with balloon catheter occlusion. The predictive accuracy of PPAP score was evaluated. RESULTS: In total, 23 of the 175 women with PP were diagnosed as having AP, histopathologically or clinically. Twenty-one of 24 women with PPAP score ≥8 had AP, whereas two of 151 women with PPAP score <8 had AP. The scoring system yielded 91.3% sensitivity, 98.0% specificity, 87.5% positive predictive value, and 98.7% negative predictive value for predicting AP in women with PP. DISCUSSION: This prospective study demonstrated that PPAP scoring system may be useful for predicting AP in women with PP.

RESUMO

BACKGROUND: CD134 (OX40), which is a cellular receptor for human herpesvirus-6B (HHV-6B) and expresses on activated T cells, may play a key role for HHV-6B replication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). OBJECTIVES: Therefore, we examined the CD134 expression on T cells and HHV-6B replication after allo-HSCT, and analyzed the correlation between them. STUDY DESIGN: Twenty-three patients after allo-HSCT were enrolled. The percentages of CD134-positive cells within the CD4+ and CD8+ cell populations were measured by flow cytometry, and the viral copy number of HHV-6B was simultaneously quantified by real-time PCR. The correlation between CD134 and HHV-6B viral load was then statistically analyzed. RESULTS: HHV-6B reactivation occurred in 11 of 23 patients (47.8%). CD134 expression was seen on T cells and was coincident with the time of peak viral load. The percentage of CD134-positive cells decreased significantly when HHV-6B DNA disappeared (p = .005 in CD4+ T cells, p = .02 in CD8+ T cells). In the 4 patients who underwent umbilical cord blood transplantation (UCBT), the viral load varied with the percentage of CD134-positive cells. In the comparison between the HHV-6B reactivation group and non-reactivation group, maximum percentages of CD134-positive cells among CD4+ T cells in reactivation group were significantly higher than those in non-reactivation group (p = .04). CONCLUSIONS: This is the first study to show that a correlation of CD134 expression on T cells with HHV-6B replication after allo-HSCT, especially in UCBT. The results possibly indicate that CD134 on T cells plays a key role for HHV-6B replication after allo-HSCT.

RESUMO

PROBLEM: Is an abnormal increase or decrease of M1/M2 macrophages observed in the deciduae of miscarriages with normal fetal chromosome (MN)? METHODS OF STUDY: Deciduae of 18 MN and 26 miscarriages with abnormal fetal chromosome (MA) were obtained. Additionally, deciduae from 15 women whose pregnancies ended in induced abortions (IA) and endometriums at the mid-luteal phase from 19 non-pregnant women endomeriums of mid-luteal phases (EM) were obtained. Macrophages were analyzed by flow cytometry using monoclonal antibodies for CD68, HLA-DR, and CD163. RESULTS: M1 macrophages, defined as CD68+ HLA-DR+ CD163- cells, increased in MN compared with MA or IA. M2 macrophages, defined as CD68+ HLA-DR- CD163+ cells, increased in the deciduae of MA and IA compared with EM. However, this increase was not observed in the deciduae of MN. CONCLUSION: Our findings of phenotypic characters of decidual macrophages in MN provide additional evidence that M2 polarization is favorable for the maintenance of early stages of pregnancy.

RESUMO

BACKGROUND: Spinal muscular atrophy (SMA) is the most common genetic neurological disease leading to infant death. It is caused by loss of survival motor neuron (SMN) 1 gene and subsequent reduction of SMN protein in motor neurons. Because SMN is ubiquitously expressed and functionally linked to general RNA metabolism pathway, fibroblasts (FBs) are most widely used for the assessment of SMN expression in SMA patients but usually isolated from skin biopsy samples after the onset of overt symptoms. Although recent translational studies of SMN-targeted therapies have revealed the very limited time window for effective SMA therapies during perinatal period, the exact time point when SMN shortage became evident is unknown in human samples. In this study, we analyzed SMN mRNA and protein expression during perinatal period by using umbilical cord-derived mesenchymal stem cells (UC-MSCs) obtained from preterm and term infants. METHODS: UC-MSCs were isolated from 16 control infants delivered at 22-40 weeks of gestation and SMA fetus aborted at 19 weeks of gestation (UC-MSC-Control and UC-MSC-SMA). FBs were isolated from control volunteer and SMA patient (FB-Control and FB-SMA). SMN mRNA and protein expression in UC-MSCs and FBs was determined by RT-qPCR and Western blot. RESULTS: UC-MSC-Control and UC-MSC-SMA expressed the comparable level of MSC markers on their cell surface and were able to differentiate into adipocytes, osteocytes, and chondrocytes. At steady state, SMN mRNA and protein expression was decreased in UC-MSC-SMA compared to UC-MSC-Control, as observed in FB-SMA and FB-Control. In response to histone deacetylase inhibitor valproic acid, SMN mRNA and protein expression in UC-MSC-SMA and FB-SMA was increased. During perinatal development from 22 to 40 weeks of gestation, SMN mRNA and protein expression in UC-MSC-Control was positively correlated with gestational age. CONCLUSION: UC-MSCs isolated from 17 fetus/infant of 19-40 weeks of gestation are expressed functional SMN mRNA and protein. SMN mRNA and protein expression in UC-MSCs is increased with gestational age during perinatal development.

RESUMO

This study aimed to evaluate whether natural killer (NK) cell activity was associated with the etiology of recurrent miscarriage (RM), and to evaluate the predictive value of NK cell activity for outcomes of following pregnancies in women with RM. Peripheral NK cell activity was measured in 160 non-pregnant women with a history of two or more miscarriages. This activity was compared according to the etiology of RM and to pregnancy outcomes in women who became pregnant. NK cell activity in women with unexplained RM was significantly higher than that in those with known etiologies of RM. NK cell activity in women whose next pregnancies ended in miscarriage of fetuses with a normal chromosome karyotype (MN) was higher than that in those with live births (p<0.05). Women with NK cell activity ≥33% had a higher risk for MN (relative risk 3.4, 95% confidence interval 1.3-8.7). An increase in peripheral NK cell activity was associated with MN. This increase might be involved in the pathophysiology underlying RM.

RESUMO

BACKGROUND: Surgical meshes are widely used in incisional hernia repair. However, there are no reports of pregnancies complicated by infection of surgical meshes used for hernia repair. This is the first case report of a pregnant woman who experienced surgical site infection associated with surgical mesh used for repair of an abdominal wall incisional hernia. CASE PRESENTATION: We report a case of a 41-year-old pregnant Japanese woman with surgical site infection after mesh repair of an abdominal wall incisional hernia. She was diagnosed with an abdominal wall incisional hernia at 3 months after her third cesarean section, and she underwent an operation of hernia repair with use of monofilament polypropylene mesh 7 months after the third cesarean section. However, a surgical site infection associated with surgical mesh occurred. During antibiotic treatment, she was found to be pregnant. She was referred to our hospital at 13 weeks and 2 days of gestation. The surgeons removed the infected mesh at 16 weeks and 3 days of gestation. Neither the hernia nor infection at the surgical site recurred throughout pregnancy. We planned a cesarean section using a transverse uterine fundal incision method with an upper abdominal incision. The patient delivered a 2478-g healthy female infant. CONCLUSIONS: The present report shows that removal of mesh can safely control surgical site infection during pregnancy.

RESUMO

Uterine leiomyosarcoma (ULMS) is an aggressive tumor associated with high rates of progression, recurrence, and mortality. Pazopanib is the only approved molecular targeted drug for advanced soft tissue sarcoma, and it has been proven to prolong progression-free survival relative to placebo. We herein report a case of ULMS with multiple lung metastases treated with pazopanib, which led to sustained disease control for 44 weeks. A 53-year-old woman was referred to our hospital due to massive uterine bleeding from a uterine corpus tumor mass. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed as emergency surgery. The final histopathological diagnosis was uterine leiomyosarcoma, and computed tomography revealed multiple lung metastases. After chemotherapy with 17 cycles of gemcitabine and docetaxel and two cycles of doxorubicin, the lung metastases had increased in size and new lesions had appeared. Pazopanib administration at 800 mg/day was started as third-line therapy. Ten weeks later, the dose of pazopanib was reduced to 600 mg/day because of hepatic impairment and hypertension. However, lung metastases of ULMS were stabilized by pazopanib administration for about 44 weeks without a decline in the patient's quality of life. After 44 weeks of therapy, pazopanib administration was discontinued because of progressive disease and worsening of the patient's respiratory status. Pazopanib is an oral multityrosine kinase inhibitor of vascular endothelial growth factor receptor-1, -2, and -3; platelet-derived growth factor-α and -ß; and c-Kit receptor. The role of pazopanib may be clinically significant in the treatment of advanced ULMS.
