Abstract
Although many cancers can be detected by whole-body positron emission tomography (PET) with 18F-fluoro-2-deoxyglucose (FDG), there has been limited clinical experience with FDG-PET for the detection of recurrent ovarian cancers. Therefore, the aim of this study was to evaluate the clinical value of FDG-PET in the detection of recurrent ovarian cancer. Whole body FDG-PET scans were performed on 24 women who had previous histories of ovarian cancer and treatment with surgery and chemotherapy. All patients also underwent physical examination, laboratory testing of serum CA-125 level and pelvic-abdominal-chest computed tomography (CT) or magnetic resonance imaging (MRI). The results of FDG-PET scans were correlated with serum CA-125 level, CT/MRI and operative pathology results. The diagnostic sensitivity was 90.9%, 90.9% and 90.9%, specificity was 92.3%, 76.9% and 46.2% and accuracy was 91.7%, 83.3% and 66.7% for FDG-PET, serum tumor marker of CA-125 level and CT/MRI in detecting recurrent ovarian cancer, respectively. FDG-PET is a useful diagnostic tool in detecting recurrent ovarian cancers with high specificity as compared with the serum tumor marker CA-125 level and the conventional CT/MRI morphological imaging methods.

Abstract
BACKGROUND/AIMS Radionuclide esophageal emptying test using a solid meal is a simple, noninvasive, and physiologic test of esophageal function. METHODOLOGY In this study, we evaluated esophageal emptying using an isotope-labeled solid meal (an egg salad sandwich labeled with 99mTc-MAA) in the assessment of pneumatic dilatation treatment in achalasia. Twenty achalasic patients (12 males, 8 females, age: 51.4 +/- 13.0 years) underwent esophageal emptying measurement before and after pneumatic dilatation. After treatment, the dysphagic symptoms of all patients improved. RESULTS In comparison with the pretreatment test, the posttreatment retention fraction at 1, 5, 10, and 15 min were significantly lower (P < 0.001). CONCLUSIONS The results suggest that radionuclide esophageal emptying test using a solid meal remains a useful objective study of esophageal function and may have an important future role in the follow-up evaluation of treatment for achalasia.

Abstract
To evaluate the clinical value of whole body positron emission tomography (PET) with 18F-fluoro-2-deoxyglucose (FDG) in recurrent cervical cancer, the records of 20 patients who underwent FDG-PET scans were reviewed to detect local recurrence, pelvic/para-aortic lymph node metastases and distal metastases. The final diagnosis was based on operative, histopathological findings or clinical follow-up for longer than one year. FDG-PET accurately detected 18 patients with recurrent diseases (12 patients with local recurrences, 16 patients with pelvic lymph node metastases, 14 patients with para-aortic lymph node metastases and 4 patients with distal metastases of other sites). However, 2 patients with local recurrences had false- negative FDG-PET results as well as 1 patient without local recurrence and 1 patient without pelvic lymph node metastases who had false-positive FDG-PET results. The overall sensitivity and specificity of FDG-PET for patients were 90% and 100%, for local recurrence were 86% and 92%, for pelvic lymph node metastases were 100% and 94%, for para-aortic lymph node metastases were 100% and 100% and for distal metastases were 100% and 100%, respectively. In conclusion, whole body FDG-PET is a useful diagnostic tool in the evaluation of recurrent cervical cancer. It appears to be promising for detecting recurrent cervical cancer, lymph node metastases and distal metastases.

Abstract
Patients with systemic lupus erythematosus (SLE) with or without definite neuropsychiatric symptoms/signs were studied. Technetium-99m (Tc-99m) hexamethylpropylenamine (HMPAO) brain images were used to detect basal ganglion and cerebral cortex regional cerebral blood flow (rCBF) in patients with SLE with brain involvement. One hundred nine female patients with SLE were investigated using Tc-99m HMPAO brain images with fan-beam single-photon emission computed tomography (SPECT) and surface three-dimensional (3D) display. These patients were separated into 2 subgroups: group 1, 74 cases with definite neuropsychiatric symptoms/signs; and group 2, 35 cases without any neuropsychiatric symptoms/signs. Fan-beam SPECT demonstrated unilateral or bilateral hypoperfusion of basal ganglia or thalamus in 22% and 9% of patients in groups 1 and 2, respectively. Local hypoactivity anomalies were found in the brain cortex of 89% and 20% of patients in groups 1 and 2, respectively, using surface 3D display of the brain. In either group 1 or group 2 patients, parietal and frontal lobes are the most common areas and cerebellum and thalamus are the least common areas of brain involvement, respectively. This study suggests that in comparison with traditional brain imaging techniques, Tc-99m HMPAO brain imaging with fan-beam SPECT in combination with surface 3D display may provide objective information for detection of anomalies of rCBF in patients with SLE.

Abstract
The aim of this study was to investigate the relationship between Technetium-99m (Tc-99m) tetrofosmin accumulation in tumors which may represent the expression of multidrug resistance (MDR)--mediated P-glycoprotein (Pgp) and multidrug resistance-associated protein (MRP) as well as response to chemotherapy in patients with untreated small cell lung cancers (SCLC). Twenty patients with SCLC were studied with Tc-99m tetrofosmin lung scintigraphy before chemotherapeutic induction. Tc-99m tetrofosmin lung scans were interpreted both visually and quantitatively. Response was evaluated upon completion of chemotherapy. Patients with good chemotherapy response had a significantly higher incidence (93%) of positive Tc-99m tetrofosmin lung single photon emission computed tomography (SPECT) findings than patients with poor response (33%) (p value < 0.05). The tumor/background ratios (T/B) were 1.8 +/- 0.4 and 1.2 +/- 0.3, for patients with good response and poor response, respectively (p < 0.05). However, other prognostic factors (tumor size and stage) were not significantly related to Tc-99m tetrofosmin lung scan findings and chemotherapy responses. Tc-99m tetrofosmin lung scintigraphy can predict chemotherapy response in patients with SCLC.

Abstract
BACKGROUND/AIMS Hepatocellular carcinoma (HCC) is usually a hypervascular tumor. Factor VIII-related antigens, including von Willebrand factor, are known to be expressed in HCC, which cause capillarization of the sinusoids of HCC. Capillarization of hepatic sinusoids may play a role in hepatocarcinogenesis and its metastasis. The aim of this study is to clarify the expression of Factor VIII in patients with hepatitis B or C (n = 18) and HCC (n = 16). METHODOLOGY All specimens were sufficient for immunohistochemical study of the neo-angiogenesis with regard to clinical results. Microvessel count per square millimeter (MVC) and hot spot of microvessel per square millimeter (HSV) were measured from the histochemical study. RESULTS In the patients with hepatitis group, the positive staining on the vessels of the portal triad was 11.1% (2/18) but in the non-neoplastic tissue of HCC patients the positive rate was 68.7% (11/16) showing a significant difference from the hepatitis group. The amount of vasculatures was easily found in the surrounding capsule of resected HCC. The MVC of the capsule was 10.17 +/- 2.78 and 13.66 +/- 5.42 for the HCC with non-direct invasion and direct invasion during operation, respectively. The HSV of capsules were 7.51 +/- 2.09 and 9.14 +/- 4.02 for the non-invasion and invasion, respectively. Therefore, in our study, it is clear that the high MVC or HSV scores were found in patients of direct invasion. However, there was no relation between hepatitis B or hepatitis C to the tumor invasiveness. The median survival times were 21.5 months for the non-invasive group and 14.5 months for the invasive group (p < 0.05). The positive rate of Factor VIII in the vessels of the portal triad were 60% and 83.3% for the non-invasive and invasive groups, respectively. However, the lower values of MVC and HSV showed a trend toward a longer recurrence time. CONCLUSIONS It is pertinent to prove that the high score of neo-angiogenesis has a high risk of recurrence. In addition, it is wise to pay more attention to the interval of the follow-up study to detect the recurrent lesion earlier, where possible, in the patient with a high score of microvascularity.

Abstract
BACKGROUND To determine the influence of smoking on 99mTc-labeled methoxyisobutylisonitrile (99mTc-MIBI) lung uptake during myocardial perfusion imaging, we examined 60 subjects with normal myocardial perfusion scans, normal coronary angiograms, and no evidence of left ventricular hypertrophy. METHODS AND RESULTS The subjects were divided into 2 groups: Group 1 subjects had smoking histories of at least 10 pack-years and Group 2 subjects were nonsmokers. 99mTc-MIBI lung to heart ratios (L/H ratios) from anterior planar images were obtained for all subjects during exercise and resting states. 99mTc-MIBI L/H ratios in smokers were significantly higher than in nonsmokers in both exercise and resting states. However, no significant difference in L/H ratios was found between exercise and resting states in smokers and nonsmokers. In addition, no significant correlation was found between smoking pack-years and either rest or exercise L/H ratios. CONCLUSIONS 99mTc-MIBI L/H ratios in smokers are higher than in nonsmokers. This must be considered when 99mTc-MIBI L/H ratios are used clinically.

Abstract
Tuberculosis (TB) remains a major cause of skeletal infection in many parts of the world. Bone scintigraphy is an excellent screening test for bone lesions and Ga-67 scintigraphy is a useful tool for detecting inflammatory lesions. This study determined the value of bone and Ga-67 scans in patients with skeletal TB. Tc-99m MDP and Ga-67 whole-body scans were performed in 24 patients with proved skeletal TB. Twenty-six TB lesions were found in these 24 patients, 8 in the spine, 5 in the knee, 5 in the wrist, 4 in the ankle, 2 in the elbow, 1 in the finger, and 1 in the sacroiliac joint. Of the 26 TB lesions, Tc-99m MDP bone imaging detected 24 and Ga-67 scans revealed 23. The sensitivity rates were 92% (24 of 26) and 88.5% (23 of 26) for bone scans and Ga-67 scans, respectively. When the scans were evaluated in combination, the detection sensitivity was 96.1% (25 of 26). Two lesions that the bone scan failed to detect were in the spine. Ga-67 imaging failed to detect two spinal lesions and one lesion in the knee. The detection sensitivities of bone and gallium scans were high for skeletal TB, although neither scan was specific for TB lesions. Either the bone or Ga-67 scan can be used in the clinical setting as a convenient screening test to detect multiple sites of bone involvement in TB, and to indicate the sites for further detailed evaluation by CT, MRI, or biopsy.

Abstract
The 99mTc-labelled RBC erection penogram (Tc-RBC penogram) coupled with intracavernosal injection of prostaglandin E1 (PGE1) was used to evaluate the penile hemodynamic changes during tumescence. As expected, the method is useful to differentiate organic from psychogenic impotence, and arteriogenic from venogenic impotence. Thirty-four patients with psychogenic impotence, 23 patients with arteriogenic impotence, and 27 patients with venogenic impotence were included in the study. A Tc-RBC penogram was performed on each patient after intracavernosal injection of PGE1. Several parameters calculated from the time-radioactivity curve of the Tc-RBC penogram were used to evaluate hemodynamic changes of the penis. They included (1) the arterial phase: slope and time to peak (TTP), and (2) the venous phase: washout index (WOI). During the arterial phase, the patients with psychogenic and venogenic impotence had higher slope and shorter TTP than those of patients with arteriogenic impotence (p < 0.01). During the venous phase, the patients with psychogenic and arteriogenic impotence had a lower WOI than that of patients with venogenic impotence (p < 0.01). We conclude that the Tc-RBC penogram is a simple, noninvasive, and valuable method for the objective differentiation among psychogenic, arteriogenic, and venogenic impotence.

Abstract
Tc-99m tetrofosmin SPECT imaging of the head and neck was performed on 10 patients with nasopharyngeal carcinoma (NPC) and 10 controls. There was no abnormal nasopharyngeal uptake of tetrofosmin in the 10 controls. In the patients with NPC, 3/10 (30%) of the cases had no abnormal uptake and 7/10 (70%) had increased nasopharyngeal uptake. Considering our preliminary study, we find that Tc-99m tetrofosmin SPECT of the head and neck may be helpful in the detection of NPC. However, further study with a larger number of patients is needed to ascertain the value of Tc-99m tetrofosmin SPECT in such cases.

Abstract
UNLABELLED Technetium-99m-tetrofosmin has emerged as a new radiopharmaceutical for myocardial imaging, in competition with 201Tl and 99mTc-MIBI. In this study, 99mTc-tetrofosmin was evaluated for its ability to detect malignant and benign lesions from single solid lung masses. METHODS Forty-nine patients with a single solid lung mass based on chest radiograph findings received 99mTc-tetrofosmin SPECT of the chest to evaluate the value of 99mTc-tetrofosmin SPECT for detecting malignant and benign lesions. RESULTS Only 61% of the lung malignancies were detected by 99mTc-tetrofosmin SPECT of the chest, including 53% of epidermoid carcinoma (ca), 67% of adeno ca, 75% of small-cell ca, 0% of undifferentiated large-cell ca and 100% of other lung malignancies. In addition, 50% of the benign lesions were detected by chest 99mTc-tetrofosmin SPECT. The probability of tetrofosmin uptake in the mass was not related to mass size. The diagnostic sensitivity, specificity and accuracy were 61%, 50% and 59%, respectively, for differentiating malignant and benign lesions when diagnosing a single solid lung mass. CONCLUSION Technetium-99m-tetrofosmin SPECT of the chest is of little or no value for the detection of lung ca from single solid lung masses.

Abstract
Technetium Tc-99m disofenin cholescintigraphy (CS) and ultrasonography (US) are two major clinical methods used in differentiating biliary atresia (BA) from neonatal jaundice. To compare the diagnostic utility of these two modalities, 66 patients with neonatal cholestasis (15 BA, 3 choledochal cyst (CC), 32 neonatal hepatitis, 13 prolonged jaundice, 2 total parenteral nutrition, and 1 sepsis) underwent Tc-99m disofenin CS and US. The diagnostic sensitivity, specificity, and accuracy of CS in differentiating BA from other forms of neonatal jaundice was 100%, 87.5%, and 90.5%, respectively, and for US 86.7%, 77.1%, and 79.4%, respectively. Tc-99m disofenin CS after premedication with phenobarbital and cholestyramine is a convenient and reliable method of differentiating BA from neonatal hepatitis, with a diagnostic accuracy superior to that of US. However, US is the initial imaging procedure of choice in patients presenting with jaundice to rule out anatomic anomalies such as CC.

Abstract
During the last two decades, there has been a trend to use low-dose I-131 ablation therapy in patients with thyroid carcinoma without metastases. However, information regarding the incidence of acute adverse reactions in patients after low-dose radioiodine therapy has not been reported. In this study, the acute radiation effects after low-dose radioiodine ablation therapy in postsurgical differentiated thyroid cancer patients was evaluated. Fifty-six patients with differentiated thyroid cancer were prospectively evaluated. None of these patients had evidence of a distant metastasis. All patients received 40 mCi (1480 MBq) I-131 MIBG orally and were evaluated for symptoms and signs by a physician on the second and seventh days after therapy. Xerostomia and nausea were the most common complaints with the same incidence rate of 5.35%. Gastralgia occurred at a frequency of 3.57%. Pain in the thyroid bed, tenderness over a parotid gland, submandibular glands, change in taste, and vomiting all were found at a frequency of 1.78%. Maximum reactions generally occurred 24-48 hours after therapy. All the symptoms except for xerostomia resolved completely in most patients within a week. In comparison with high-dose ablation therapy published in the literature, the incidence of radiation reactions in low-dose radioiodine therapy was much lower. It was concluded that in patients without lymph node or distant metastases, low-dose I-131 MIBG therapy may be recommended to avoid the high incidence of local complications after high-dose treatment.

Abstract
Bone scintigraphy plays an important role in the early detection of bone metastases in patients with nasopharyngeal carcinoma and serial scans may aid the clinician to assess the therapeutic response. A superscan is a pattern described as abnormal bone scan, indicating extensive bony metastases associated with various neoplastic diseases. Bone scans from 407 patients with nasopharyngeal carcinoma were reviewed retrospectively. Only six superscans (1.5%) were found. The appearance of a superscan is frequently accompanied by an abnormal titer of serological markers IgG-VCA and IgA-VCA, liver metastases, and poor survival. Although a superscan rarely occurs in nasopharyngeal carcinoma, its appearance may represent a poor prognosis in these patients.

Abstract
Secretory breast carcinoma is a very rare tumor of the breast and has distinctive pathological characteristics such as (1) the presence of large amounts of intracellular and extracellular secretion and (2) granular eosinophilic cytoplasma of the cells. It usually occurs in children or adolescents and is known to have a better prognosis than the usual ductal carcinoma. The preoperative aspiration cytology is also distinctive and it could permit planning the optimal surgical therapy such as breast conservation surgery for young patients. We report a case of secretory breast carcinoma in a 35 year-old female and her preoperative aspiration cytology in Liu's stain. To our knowledge, Secretory breast carcinoma has not been reported previously in Taiwan.

Abstract
Mitochondrial myopathy, encephalopathy with lactic acidosis and stroke-like episodes (MELAS) syndrome is one of the mitochondrial encephalomyopathies that has distinct clinical features including stroke-like episodes with migraine-like headache, nausea, vomiting, encephalopathy and lactic acidosis. We report a 27-year-old woman who presented with partial seizure, stroke-like episodes including hemiparesis, hemianopia and hemihypethesia, sensorineural hearing loss, migraine-like headache, and lactic acidosis. Brain computed tomographic scan showed encephalomalacia in the right parieto-occipital area and recent hypodensity in the left temporoparieto-occipital area with cortical atrophy. Muscle biopsy revealed ragged-red fibers and paracrystaline inclusions in the mitochondria. Genetic study revealed an A to G point mutation at nucleotide position (np) 3243 of mitochondrial DNA. External ophthalmoplegia and ptosis were also found during two exaggerated episodes in this patient. Therefore, the overlapping syndrome of chronic progressive external ophthalmoplegia in the MELAS syndrome is considered in this case. Furthermore, we also found carnitine deficiency in this patient and she was responsive well to steroid therapy. Muscle biopsy also revealed excessive lipid droplets deposits. Therefore, the carnitine deficiency may occur in MELAS syndrome with the A to G point mutation at np 3243. We recommend the steroid or carnitine supplement therapy be applied to the MELAS syndrome with carnitine deficiency.

Abstract
Serum interleukin-2 receptor (sIL-2R) level activities of natural killer cell (NK) and lymphokine activated killer cell (LAK) cells were determined in 60 patients with advanced carcinoma (AC) before and after treatment with Shenmai injection (SMI), 40 healthy persons were taken as non-carcinoma control (NC). The results showed that: Serum sIL-2R level in AC were much higher than those in NC (P < 0.05) and activities of NK and LAK cells in AC were much lower than those in NC (P < 0.05) before treatment. There was no significant difference among gastric cancer, colonic carcinoma and lung cancer (P < 0.05). After treatment with SMI we also found that the level of sIL-2R in all patients were obviously lower (P < 0.05) while the activity of NK and LAK cells were significantly higher than that prior treatment (P < 0.05). Linear correlation was not found between sIL-2R and NK, LAK cells. These data suggested that the immune function was compromised in AC. The mechanism of the inhibitory effect of SMI on carcinoma might be related to the activity of biological response modifier.

Abstract
Varicocoeles could be classified into stop-type and shunt-type. In stop-type varicocoeles, only the internal spermatic (testicular) vein is dilated and needs to be ligated. In shunt-type, both internal spermatic vein and external spermatic (cremasteric) vein are dilated due to incompetence of the cremasteric system and both venous systems require ligation. Two-phase (flow and static) scrotal scintigraphy was performed on 92 patients preoperatively. Forty-three patients in whom the testicular and cremasteric veins could be verified during operation were included in this study. All 43 patients had unilateral varicocoeles and had abnormal blood pooling in the affected spermatic cord and hemiscrotum. In the blood flow study, 22 of 27 shunt-type varicocoeles had abnormal flow in the spermatic cord whereas only one out of 16 stop-type varicocoeles had increased blood flow. No difference in the results of semen analysis was found between the two groups of patients. Two-phase scrotal scintigraphy provides a noninvasive evaluation of shunting of the retrograde venous flow from the internal spermatic to the external spermatic vein. Understanding this pathophysiological change would be of benefit in the decision making about a surgical approach to varicocoeles.

Abstract
Cytoplasmic IgA+, IgG+ and IgM+ in plasma cells, present in biopsy tissue of 68 patients with nasopharyngeal carcinoma (NPC) and 40 patients with chronic nasopharyngitis (CN), were studied by immunoperoxidase (PAP) technique. EB virus VCA-IgA serum antibody in all these patients was determined. At the same time, the activity of T lymphocytes of 41 patients (23 with NPC and 18 with CN) was investigated by alpha-naphthyl acetate esterase (ANAE) method. The number of T lymphocytes in NPC was far less than that in CN. This suggests that the impediment or deficiency in cellular immunity may promote the development and growth of tumor. The number of IgA+ plasma cells in NPC was obviously more than that in CN. As the increase in the level of VCA-IgA serum antibody in NPC patients corresponded to the increase in the number of IgA+ plasma cells in the tumor tissue, it was presumed that part of the IgA+ plasma cells might participate in the production and introduction of VCA-IgA antibody. We suggest that the examination of VCA-IgA serum antibody be a reliable screening test for NPC. No significant difference was found in the numbers of IgG+ plasma cells between NPC and CN. IgM+ plasma cells were rare in both.
