Abstract
INTRODUCTION Patent foramen ovale (PFO) is present in a significant proportion of young patients with stroke of undetermined etiology, but is not always causal. Therefore, classifications (RoPE, PASCAL) have been developed to determine the probability that PFO is the stroke cause. However, the presence of an initial arterial occlusion as a prediction factor was not studied when these classifications were built. Our aim was to evaluate the presence of arterial occlusion in young patients with stroke of undetermined etiology with/without high-risk PFO. METHODS From a prospectively-built monocentric database, we identified patients aged≥18 to<60-years with strokes of undetermined etiology and complete etiological work-up, including transesophageal echocardiography. We divided patients in two groups: (i) with high-risk PFO [i.e. PFO with large interatrial shunt (>30 microbubbles) or associated with atrial septal aneurysm] and (ii) with low-risk/without PFO. We recorded the presence of arterial occlusion and large vessel occlusion (LVO) in the acute phase. RESULTS We included 96 patients; 55 (57%) had high-risk PFO. Their median age was 48 (40-52) years, and 28 (29%) were women. The percentages of patients with arterial occlusion and with LVO were lower in the high-risk PFO group than in the low-risk/without PFO group: 11 (20%) versus 19 (46%) (P=0.008), and 5 (9%) versus 15 (37%) (P=0.002), respectively. There was no difference in the median RoPE score between groups (P=0.30). CONCLUSION The presence of LVO could represent a "red flag" of PFO causality in stroke of undetermined etiology, and could be implemented in future PFO-related stroke classifications.

Abstract
Abstract
Study question
Do viable pregnancies after transfer of mosaic blastocysts present different perinatal outcomes as compared to those deriving from transfer of euploid blastocysts?
Summary answer
Pregnancies from transfer of mosaic vs. euploid blastocysts showed an increased rate of fetal structural malformations and postpartum haemorrhages (PPH).
What is known already
The incidence of mosaicisms in the trophoectoderm is a relatively frequent event and most true embryo mosaicisms result in spontaneous intrauterine demise. The confirmation of the mosaic aneuploidy in the fetus is related to the type and grade of the aneuploidy with higher risk for chromosomes 13, 14, 15, 16, 18 and 21 and X monosomy. On the other hand, selected mosaic blastocysts have been transferred with subsequent birth of healthy neonates. However, the risk of abnormal obstetric outcomes after transfer of mosaic embryos remains to be completely elucidated.
Study design, size, duration
Explorative cohort study between 2016 and 2021 including consecutive viable ART pregnancies developing from transfer of mosaic blastocysts (n = 39 cases). Transfer of available mosaic embryos was considered for patients with a poor response to ovarian stimulation or recurrent implantation failures and no available euploid blastocysts, after genetic counselling. Cases were matched for maternal age, parity and body mass index to women with viable pregnancies after transfer of euploid blastocysts (n = 39, controls) and followed-up until delivery.
Participants/materials, setting, methods
All patients recruited at San Raffaele, Scientific Institute of Milan, underwent a prenatal genetic testing by trophoectoderm biopsy and next-generation sequencing analysis. Patients with a viable fetus at 12 weeks gestation were included and underwent detailed ultrasound assessment at 12, 20 and 32 weeks including fetal biometry and anatomical survey. Frequency of adverse pregnancy and perinatal outcomes including maternal, fetal and delivery complications were compared between patients who received a mosaic versus a euploid blastocyst.
Main results and the role of chance
No difference in indications to preimplantation diagnosis was found between cases and controls. In the group who transferred mosaic embryos, median rate of mosaicisms was 35% (IQR 30%-40%) and they were characterized by heterogeneous anomalies including complex aneuploidies (n = 12), autosomal monosomies (n = 13), trisomies (n = 8) and duplications/deletions (n = 6). Invasive testing was performed in 62.0% of mosaics (5 chorion villous samplings; 19 amniocenteses; 2 anomalies: confined placental mosaicism trisomy 15 after transfer of mosaic monosomy 6 and fetal microduplication 6p after transfer of mosaic deletion 10p) vs 2.5% of controls (p < 0.001). Structural malformations were observed in 6 neonates in the study group (tanatophoric skeletal dysplasia, complex central nervous system anomaly, congenital diaphragmatic hernia, cerebral arteriovenous fistulae, pyeloureteral junction stenosis, diffuse haemangiomatosis) compared to 1 in controls (pulmonary stenosis) (p = 0.04). One neonate per group was followed-up for future surgery. PPH rate was significantly higher in cases vs controls (15 vs 7; p = 0.04). Neonatal survival at hospital discharge was not different in the two groups (p = 0.30). No significant differences were recorded in rates of preterm birth, small or large for gestational age, fetal growth restriction, miscarriage, preeclampsia and median birthweight centile or gestational age at birth.
Limitations, reasons for caution
Data from our exploratory study should be interpreted cautiously given the limited sample size which makes it challenging to infer a causal relationship between the association found and transfer of mosaic blastocysts.
Wider implications of the findings
The higher rates of structural malformations and PPH in ART pregnancies after transfer of mosaic embryos strongly suggest the need for strict monitoring of these patients. First and second trimester ultrasound screening for structural defects, and preventive measures to minimize bleeding at delivery should be implemented.

Abstract
BACKGROUND AND PURPOSE The best transportation strategy for patients with suspected large vessel occlusion (LVO) is unknown. Here, we evaluated a new regional strategy of direct transportation to a Comprehensive Stroke Center (CSC) for patients with suspected LVO and low probability of receiving intravenous thrombolysis (IVT) at the nearest Primary Stroke Center (PSC). METHODS Patients could be directly transported to the CSC (bypass group) if they met our pre-hospital bypass criteria: high LVO probability (i.e., severe hemiplegia) with low IVT probability (contraindications) and/or travel time difference between CSC and PSC<15 minutes. The other patients were transported to the PSC according to a "drip-and-ship" strategy. Treatment time metrics were compared in patients with pre-hospital bypass criteria and confirmed LVO in the bypass and drip-and-ship groups. RESULTS In the bypass group (n=79), 54/79 (68.3%) patients met the bypass criteria and 29 (36.7%) had confirmed LVO. The positive predictive value of the hemiplegia criterion for LVO detection was 0.49. In the drip-and-ship group (n=457), 92/457 (20.1%) patients with confirmed LVO met our bypass criteria. Among the 121 patients with bypass criteria and confirmed LVO, direct routing decreased the time between symptom discovery and groin puncture by 55 minutes compared with the drip-and-ship strategy (325 vs. 229 minutes, P<0.001), without significantly increasing the time to IVT (P=0.19). CONCLUSIONS Our regional strategy led to the correct identification of LVO and a significant decrease of the time to mechanical thrombectomy, without increasing the time to IVT, and could be easily implemented in other territories.

Abstract
INTRODUCTION stereotactic ablative radiotherapy (SABR) has been shown to increase survival in oligometastatic disease, but local control of colorectal metastases remains poor. We aimed to identify potential predictive factors of SBRT response through a multicenter large retrospective database and to investigate the progression to the polymetastatic disease (PMD). MATERIAL AND METHODS the study involved 23 centers, and was approved by the Ethical Committee (Prot. Negrar 2019-ZT). 1033 lung metastases were reported. Clinical and biological parameters were evaluated as predictive for local progression-free survival (FLP). Secondary end-point was the time to the polymetastatic conversion (tPMC). RESULTS Two-year FLP was 75.4%. Two-year FLP for lesions treated with a BED <100 Gy, 100-124 Gy, and ≥125 Gy was 76.1%, 70.6%, and 94% (p=0.000). Two-year FLP for lesion measuring ≤10 mm, 10-20 mm, and >20 mm was 79.7%, 77.1%, and 66.6% (p=0.027). At the multivariate analysis a BED ≥125 Gy significantly reduced the risk of local progression (HR 0.24, 95%CI 0.11-0.51; p=0.000). Median tPMC was 26.8 months. Lesions treated with BED ≥125 Gy reported a significantly longer tPMC as compared to lower BED. The median tPMC for patients treated to 1, 2-3 or 4-5 simultaneous oligometastases was 28.5, 25.4, and 9.8 months (p=0.035). CONCLUSION The present is the largest series of lung colorectal metastases treated with SABR. The results support the use of SBRT in lung oligometastatic colorectal cancer patients as it might delay the transition to PMD or offer relatively long disease-free period in selected cases. Predictive factors were identified for treatment personalization.

Abstract
Abstract
Study question
To explore the effect of chromosomal mosaicism detected in preimplantation genetic testing (PGT-A) on prenatal and postnatal outcome of mosaic embryo pregnancies
Summary answer
No significant difference between euploid and mosaic embryos was observed in terms of weeks of gestation, average weight, and developmental defect of the babies born
What is known already
Mosaic embryos have the potential to implant and develop into healthy babies. Transfer of these embryos is now offered as an option for women who undergo IVF resulting in no euploid embryos. While, prenatal diagnosis has shown the depletion of chromosomal mosaicism in mosaic embryos, several concerns remain. For instance, the direct effects of different kind of mosaicism on prenatal/postnatal outcome and the possibility that intra-biopsy mosaicism in the TE is a poor predictor of the ploidy status of the ICM. Thus, there is certainly a need for comprehensive analyses of obstetrical and neonatal outcome data of transferred mosaic embryos.
Study design, size, duration
Compiled analysis from multicenter data on transfers of mosaic embryos (n = 1,000) and their outcome, with comparison to a euploid control group (n = 5,561). To explore the effect of embryonic mosaicism on newborns, we matched mosaic embryos resulting in a birth with a euploid embryo by a series of parameters (maternal age, embryo morphology, and indication for PGT-A). Prenatal tests and birth characteristics of > 200 neonates from mosaic embryo transfers were compared to > 200 euploid embryos.
Participants/materials, setting, methods
PGT-A was performed on blastocyst-stage embryos with 24-Chromosome whole genome amplification (WGA)-based Next Generation Sequencing (NGS). In accordance with established guidelines, embryos were categorized as mosaic when PGT-A results indicated 20-80% aneuploid content. Prenatal testing where performed in 30% of pregnancies with amniocentesis, 4% did an extra analysis for potential UPD for the suspected mosaic chromosome, and an additional 16% performed chorionic villus sampling (CVS) and 9.5% performed noninvasive prenatal testing (NIPT).
Main results and the role of chance
Of the 465 mosaic embryos that implanted, about 20% miscarried, and out of those, 75% were early spontaneous abortions. Of the pregnancies, 3 out of 368 were stillborn (2 out of them were twins that were extremely premature at 23 weeks, and the other died during pregnancy from a heart defect). The remaining 99% of those have been born or are late ongoing pregnancies at the time of analysis. Prenatal tests were performed in > 200 pregnancies and the vast majority tested normal. All 5 abnormal cases were amniocentesis tests showing microdeletions or insertions of sizes smaller than the resolution used during PGT-A, so they were unrelated to the mosaicism detected with PGT-A. In fact, in none of the cases did the prenatal test reflect the mosaicism detected at the embryonic stage. Matching each of the 162 mosaic embryos resulting in a birth with a euploid embryo, we found that the length of gestation was similar on average, and so was the average weight of the babies at birth. We also gathered information on the routine physical examination performed on babies at birth, and of those 162 babies from mosaic embryo transfers, none had obvious developmental defects or gross abnormalities.
Limitations, reasons for caution
Even though newborns resulting from mosaic embryo transfers in this study invariably appeared healthy by routine examination, concerns for long-term health cannot yet be entirely dispelled. The question must therefore be carefully considered by each clinic and patient situation.
Wider implications of the findings
Prenatal testing of > 200 pregnancies from mosaic embryo transfers showed no incidence of mosaicism that matched the PGT-A findings, indicating the involvement of self-corrective mechanisms. Pregnancy and obstetric data indicates that mosaic embryos prevailing through gestation and birth have similar chromosomal and physiological health compared to euploid embryos.

Abstract
Abstract
Study question
Does concomitant letrozole administration during COS alter Ki–67 expression in women undergoing FP procedures before breast cancer surgery?
Summary answer
Concomitant letrozole administration during COS, even for a short period, can reduce Ki–67 expression in breast cancer.
What is known already
The biggest concern with COS in breast cancer patients is the increase in serum estradiol levels, caused by the development of multiple follicles simultaneously. This has always been a major hindrance to the use of traditional ovarian stimulation regimens in these patients, due to the large amount of evidence on the pathogenetic role of estrogen in breast cancer propagation. To limit the rise of estradiol during COS, most centers have adopted concomitant letrozole administration. Recently, some studies have reported changes in tumor pathology after letrozole administration, such as a significant fall in Ki–67 expression.
Study design, size, duration
Case report including 2 patients undergoing COS with concomitant letrozole administration for 12 days before breast cancer surgery.
Participants/materials, setting, methods
The first patient was a 28-year-old Caucasian woman with a breast biopsy showing an infiltrating ductal carcinoma in the upper external quadrant of the right breast. The second patient was a 33-year-old Caucasian woman with a diagnosis of infiltrating ductal carcinoma of the upper external quadrant of the left breast. Both patients underwent COS with concomitant letrozole administration 5 mg daily for 12 days. Ovarian stimulation was performed using a GnRH-antagonist random-start protocol.
Main results and the role of chance
In the first patient, Ki–67 expression in the initial biopsy was 55%. After completion of FP procedures, she underwent quadrantectomy with sentinel-lymphnode biopsy. In the final histopathological report Ki–67 expression fell to 25%. In the second patient, the first biopsy showed a Ki–67 expression of 30%, while after mastectomy it fell to 10%.
Limitations, reasons for caution
Only 2 patients were included in the study.
Wider implications of the findings: COS is feasible before breast cancer surgery, as long as an adequate cancer biopsy with immunohistochemical evaluation has been collected. Cytological diagnosis is not enough to start FP procedures. Evaluation of biological parameters after letrozole administration could lead to underestimation of cancer proliferation rate and to inappropriate treatment strategies.

Abstract
BACKGROUND Pemphigus is an autoimmune bullous disease mediated by autoantibodies targeting epithelial cell-cell adhesion molecules. Predictors of relapse have not yet been clearly identified. AIMS To identify factors at diagnosis and during follow-up that could be predictors of relapse. METHODS Clinical and immunopathological data at diagnosis, clinical remission and first relapse from patients with pemphigus vulgaris or foliaceus and at least a 36-month follow-up were collected retrospectively. Based on the autoantibody profile at diagnosis, three serological patient subsets were devised: (i) anti-desmoglein (Dsg)1-positive and anti-Dsg3-negative; (iii) anti-Dsg1-negative and anti-Dsg3-positive; and (iii) anti-Dsg1-positive and anti-Dsg3-positive. RESULTS Data from 143 patients were collected. No significant differences were found between relapsers (n = 90) and nonrelapsers (n = 53) for time to remission or for anti-Dsg1 and anti-Dsg3 titres at diagnosis and remission. In the analysis of all patients, a higher risk of relapse was found for a body surface area (BSA) score of 3 compared with BSA < 3 (OR = 3.30, 95% CI 1.17-9.28; P = 0.02) and for a positive titre of either anti-Dsg1 or anti-Dsg3 autoantibodies at remission compared with both being negative (OR = 2.42, 95% CI 1.21-4.85, P = 0.01). In patients who were anti-Dsg3-positive and anti-Dsg1-negative at diagnosis, failure to achieve anti-Dsg3 negativity at clinical remission was a significant predictor of relapse (OR = 7.89, 95% CI 2.06-30.21; P < 0.01). Similarly, failure to achieve anti-Dsg1 negativity at clinical remission was a significant predictor of relapse in patients with both anti-Dsg1 and anti-Dsg3 positivity at diagnosis (OR = 5.74, 95% CI 1.15-28.61; P = 0.03), but not in those who were anti-Dsg1-positive/anti-Dsg3-negative at diagnosis (OR = 1.08, 95% CI 0.27-4.30; P = 0.91). CONCLUSION Regardless of pemphigus subtype, autoantibody titre negativity at clinical remission in patients classified based on their anti-Dsg1 and anti-Dsg3 profile at diagnosis and BSA were useful tools in predicting relapse.

Abstract
BACKGROUND AND PURPOSE Carotid webs (CaW) may be an under-recognized cause of anterior circulation cryptogenic ischemic stroke (ACIS). Prevalence is still unknown in European patients with ACIS. OBJECTIVE To evaluate the prevalence of CaW in ACIS and describe patients with CaW phenotype in a cohort of patients from a French stroke center. METHODS We conducted a retrospective monocentric cohort study from 01/01/2015 to 31/12/2019 (Montpellier University Hospital, France), in consecutive anterior ischemic stroke (AIS) patients ≤65 years old from a prospective stroke database. Using ASCOD phenotyping, ACIS patients were selected and cervical CTA were reviewed to find CaW. RESULTS Among 1053 consecutive AIS patients, 266 ACIS patients with CTA were included. Among patients included (mean age 50, women 58%), CaW was in the ipsilateral carotid (iCaW) in 21 patients: 7.9% (95%CI [4.6-11.1]), (mean age 51, 11 women, 16 Caucasian). iCaW were uncovered during study review of CTA in 6/21 (29%) patients. Comparison between patients with iCaW and those without iCaW showed no differences except that of a higher rate of intracranial large vessel occlusion (LVO) (62.4 vs 37.6%; p = 0.03). Patients with iCaW under conservative medical therapy had an annualized stroke recurrence rate (SRR) of 11.4% (95%CI [8.4-15.1]. CONCLUSIONS iCaW was identified as a source of stroke in about 8% of a French population ≤65 years with ACIS. iCaW was associated with a higher rate of LVO and a high SRR under conservative medical therapy.

Abstract
Steward's type of neoplastic disease is rare. Much has been discussed on the histopathology of this granuloma. Most authors define it as a neoplasm of the lymphoid system, and it is a subgroup of the « midline granuloma syndrome ». We report a case of a 19-year-old first treated with chemotherapy (cyclophosphamide and prednisone) and then with radiotherapy, with good results.

Abstract
Hematoporphyrin orally administered to rats largely precipitates in the stomach thus reaching the various tissues at a very slow rate. Whatever the administration pathway (oral, i.p., i.V.), hematoporphyrin is eliminated in the feces with no apparent chemical modification; the elimination is slower from rats affected by ascites hepatoma than from normal rats owing to the high affinity of tumor cells for the porphyrin.

Abstract
BACKGROUND Dehydration is a frequent clinical problem. No single laboratory value has been found to be accurate; however, the BUN/Creatinine Ratio appears the most sensitive parameter. The respiratory variation (Caval Index, CIn) in the diameter of the inferior vena cava has been investigated as a non-invasive marker for the intravascular volume status. AIM The present study is performed with the aim to explore the relationship between CIn and BUN/creatinine ratio. PATIENTS AND METHODS This prospective, observational study was conducted at Emergency Department (ED) of San Paolo Hospital (Savona, Italy), in October 2011. RESULTS 113 patients were considered eligible (mean age of 63 years). We found a good correlation between CIn and BUN/Cr Ratio (Pearson Index 0.76, p < 0.001). Receiver operator characteristic curve (ROC) analyses indicated that the maximum value was 0.884 (p < 0.0001) and corresponded to CIn 60.7%, (sensitivity 79%, specificity 89%). CIn was a good predictor for patients with BUN/Cr ratio greater than 20, and was particularly strong in determining patients with lower BUN/Cr ratio. DISCUSSION Our study suggests that inferior vena cava could provide indications on the state of hydration of the patients: we found that a caval index greater than or equal to 60% was associated with a BUN/Cr Ratio over 20, which is considered an important marker for dehydration. Therefore, bedside sonography can give emergency physicians immediate information on patient volume status long before obtaining laboratory findings. CONCLUSIONS Our study seems to support the hypothesis that CIn can be a useful bedside marker to predict dehydration in Emergency Department (ED) patients.

Abstract
The major symptom at diagnosis of endometrial cancer is post-menopausal bleeding; it is present in around 90% of cases. Singular bone metastasis is described as an uncommon site for endometrial cancer at diagnosis, showing in just 5-6% of cases. In this report we describe a rare presentation of a singular bone metastasis because of endometrial cancer of a woman with previous diagnosis of early breast cancer. A review of literature uncovered some cases of bone metastasis at presentation of endometrial cancer and that it can occur as first symptom of cancer before vaginal bleeding. This rare presentation of uterine cancer needs to be studied and described because it may be seen and needs a homogeneous treatment to improve survival.

Abstract
This study was performed to assess the efficacy and safety of docetaxel, cisplatin and fluorouracil combination in patients with unresectable locally advanced oesophageal squamous cell carcinoma. Treatment consisted of docetaxel 60 mg m−2, cisplatin 75 mg m−2 on day 1 and fluorouracil 750 mg m−2 day−1 on days 2–5, repeated every 3 weeks for three cycles, followed by carboplatin 100 mg m−2 week−1 for 5 weeks and concurrent radiotherapy (45 Gy in 25 fractions, 5 days week−1). After radiotherapy, eligible patients either underwent an oesophagectomy or received high dose rate endoluminal brachytherapy (HDR-EBT). Thirty-one out of 37 enrolled patients completed the planned chemotherapy and 30 completed chemoradiation. After completion of chemotherapy, 49% (95% CI: 32.2–66.2) had a clinical response. Twelve patients (32%) underwent a resection, which was radical in 60% (postoperative mortality: 0%). A pathological complete response was documented in four patients (11% of enrolled, 30% of resected). The median survival was 10.8 months (95% CI: 8.1–12.4), and the 1- and 2-year survival rates were 35.1 and 18.9%, respectively. Grade 3–4 toxicities were neutropoenia 32%, anaemia 11%, non-neutropoenic infections 18%, diarrhoea 6% and oesophagitis 5%. Nine patients (24%) developed a tracheo-oesophageal fistula during treatment. Even if the addition of docetaxel to cisplatin and 5-fluorouracil (5-FU) seems to be more active than the cisplatin and 5-FU combination, an incremental improvement in survival is not seen, and the toxicity observed in this study population is of concern. In order to improve the prognosis of these patients, new drugs, combinations and strategies with a better therapeutic index need to be identified.

Abstract
PURPOSE Prognosis and treatment of esophagus and cardia cancer (ECC) depend on the precision with which the disease is staged according to the American Joint Committee of Cancer (AJCC) criteria. Imaging modalities normally used in clinical staging are esophagography, esophagoscopy, endoscopic ultrasound (EUS), computed tomography (CT) and positron emission tomography- CT fusion (CT-PET). The combination of these methods is crucial in determining not only the right diagnosis but also the stage and follow-up after multimodal treatment. The purpose of our investigation was to define the role of each imaging modality in determining the most appropriate treatment options in patients with ECC. MATERIALS AND METHODS Fifty-six patients with ECC diagnosed by X-ray of the upper digestive tract, endoscopy and biopsy were staged using EUS, chest and abdomen CT scan, and CT-PET. Thirty-four patients in stage II and 18 patients in stage III underwent surgery after neoadjuvant chemotherapy; four patients in stage IV were treated with the positioning of an endoprosthesis after chemoradiotherapy. In the 52 patients who had surgery, follow-up included digestive tract X-ray, endoscopy and CT of the chest and abdomen every 6-8 months for the first 3 years. CT-PET was only performed in patients with a clinical suspicion of recurrence and/or CT findings suspicious of persistent disease (12 cases). RESULTS In all 56 patients, endoscopy, EUS, CT and CT-PET in combination were crucial in determining the site of disease, locoregional extent and depth of esophageal wall penetration (T), and any involvement of the mediastinal lymph nodes (N1), extrathoracic lymph nodes (M1) or hepatic metastases. In the locoregional staging of ECC before chemotherapy, we were able to differentiate T2-T3 from T4 in 40 patients; T4 disease was found in 12 potentially resectable cases. We were able to distinguish N0 from N1 in 12 patients. In four cases, the presence of small lymph node and/or liver metastases prompted positioning of an endoprosthesis. The specificity of CT in detecting small lymph nodes in the mediastinum was less than 50% while for CT-PET, it was more than 80%; EUS revealed sensitivity higher than 90% but a low specificity in seven cases. Only CT-PET revealed metastatic subdiaphragmatic lymph nodes (diameter <15 mm) in three cases. Presurgical restaging of the 18 patients (stage III) who had chemotherapy was based on endoscopy, EUS, CT of the chest and abdomen and CT-PET (only in suspected cases) and was compatible with surgery. Anastomotic recurrence was diagnosed in 16 patients by endoscopy with associated biopsy; any intramediastinal spread from anastomotic recurrences was evaluated by chest CT, and CT-PET in suspected cases. CONCLUSIONS X-ray of the upper digestive tract and chest and abdomen CT scan are useful in preliminary evaluation of ECC. Endoscopy is particularly indicated for evaluating tumour morphology, taking biopsies for a histological diagnosis and the early diagnosis of anastomotic recurrences. EUS is indicated mainly for evaluating T stage before and after chemotherapy or chemoradiotherapy. CT-PET is extremely useful in identifying small mediastinal metastatic lymph nodes (N1) or extrathoracic lymph nodes (M1) and hepatic metastases (</=1 cm), which may escape multislice CT. PET alone is useful for identifying residual or recurrent tumour in the esophageal wall when an endoprosthesis is in place.

Abstract
The use of ionizing radiation for tumor treatment represents a well established therapeutic modality. The efficiency and selectivity of radiotherapeutic protocols can be often enhanced by the addition of specific chemical compounds that optimise the response of the tumor to the incident radiation as compared with peritumoral tissue districts. The results of this study showed that Photofrin, a porphyrin derivative which is presently used as a tumor-photosensitizing agent in photodynamic therapy (PDT), can also act as an efficient tumor radiosensitizer. To test this possibility, we used nude mice subcutaneously implanted with human bladder cancer RT4. The mice were injected with different porphyrin-type photosensitizing agents, including Photofrin, 5-aminolevulinic acid, chlorin e(6), haematoporphyrin, protoporphyrin, Zn-tetrasulphophtalocyanine, and irradiated with 5 and 15 Gy using a Siemens X-ray device. Even though all the porphyrins accumulated in significant amounts in the neoplastic lesion, only Photofrin significantly improved the response of the tumor to irradiation by increasing the doubling time of the tumor volume from 6.2 days in the untreated control group to 10.9 days in the 5 and 15 Gy-irradiated groups. The tumor response was maximal with injected Photofrin doses of 7.5 mg/kg, and was not further enhanced by injection of higher doses. Our hypothesis is, that the radiosensitizing effect of Photofrin seems to be due to some oligomeric constituents which could specifically react with radiogenerated-radicals thereby amplifying the effect of the X-ray radiation.

Abstract
BACKGROUND AND OBJECTIVE The use of ionizing irradiation as radiation therapy (RT) for tumor treatment represents a well-established method. The use of photodynamic therapy (PDT), especially with Photofrin II, for tumor treatment is also known. Chemical modifiers enhancing the action of radiation therapy are well known and widely used in medicine. None of these compounds, however, is a selective radiosensitizer. MATERIALS AND METHODS Several series of animal experiments were performed. The highly differentiated human bladder cancer cell line RT4 was implanted subcutaneously in nude mice. The mice were injected 10 mg/kg Photofrin II and irradiated with 5 Gy. RESULTS Photofrin II has proved to be a chemical modifier of ionizing irradiation, enhancing the tumor doubling time (tumor growth) from 6.2 to 10.9 days in the control group with the use of irradiation and injection of porphyrin. CONCLUSION Photofrin II shows a high activity as radiosensitizer and, in the future, can be used as a selective radiosensitizer for tumor treatment with ionizing radiation.

This randomized phase II trial was performed to define the activity and toxicity of the combination of dacarbazine (DTIC), carmustine (BCNU), cisplatin (DDP) and tamoxifen (DBDT regimen) versus DTIC alone in patients with metastatic melanoma. Sixty patients with metastatic melanoma were randomly assigned to receive BCNU 150 mg/m2 intravenously (i.v.) on day 1, cisplatin 25 mg/m2 i.v. daily on days 1 to 3, DTIC 220 mg/m2 i.v. daily on days 1 to 3 and tamoxifen 160 mg orally daily for 7 days prior to chemotherapy (DBDT arm; arm A). Treatment cycles were repeated every 28 days, while BCNU was given every two cycles. The DTIC arm (arm B) patients received DTIC alone 1200 mg/m2 i.v. on day 1, repeated every 21 days. Patients were evaluated every two cycles; responding patients continued the treatment for a maximum of 12 cycles. The overall response rate was 26% in the DBDT arm and 5% in the DTIC arm. Complete responses were 2.5% for DBDT and 0% for DTIC. The median progression-free survival and the median survival were 4 and 9 months, respectively for DBDT, and 2 and 7 months for DTIC. DBDT was associated with significant haematological toxicity: 33% of the patients experienced a grade III or IV neutropenia and 28% a grade III or IV thrombocytopenia. In conclusion, the overall response rate obtained with DBDT was greater than that obtained with DTIC alone; however, this combination increases toxicity with limited impact on overall survival.

Abstract
Hypoxia inducible factor 1a and 2a (HIF-1a and HIF-2a) are key proteins regulating cellular response to hypoxia. Because the efficacy of photodynamic therapy (PDT) is dependent on the presence of oxygen, the assessment of HIF-1a and HIF-2a expression may be of value in predicting clinical response to PDT. Using recently produced MoAbs, we examined the expression of HIF1a and HIF2a in a series of 37 early-stage esophageal cancers treated with PDT and with additional radiotherapy in case of incomplete response after PDT. Strong expression of the HIF1a and of HIF2a proteins in all optical fields examined was noted in 51% and in 13% of cases, respectively. High expression was associated with a low complete response (CR) rate and with the absence of bcl-2 protein expression. On the contrary, bcl-2 expression was associated with a high CR rate. Combined analysis of HIF1a and bcl-2 protein expression revealed that of 16 cases with high HIF1a expression and the absence of bcl-2 reactivity, only 1 (7%) responded completely to PDT (P = 0.007). Bivariate analysis showed that HIF1a expression was independently related to response to PDT (P = 0.04; t ratio = 2.8), whereas bcl-2 approached significance (P = 0.07; t-ratio = 1.8). The final response to radiotherapy was high (70%) and independent of the HIF and bcl-2 status, which may be a result of reoxygenation after cellular depletion mediated by PDT. The present study suggests that assessment of HIF and of bcl-2 expression are important predictors of in vivo sensitivity to PDT. Modulation of PDT response with bioreductive drugs and/or drugs targeting bcl-2 (i.e., taxanes) may prove of significant therapeutic importance in a subgroup of patients with high HIF expression.

Abstract
PURPOSE The role of apoptosis related proteins in the response of human malignancies to photodynamic therapy (PDT) is under investigation. The aim of the study was to examine the role of p53 and of bcl-2 protein expression in the response to PDT. MATERIALS AND METHODS Paraffin-embedded material from 37 patients with early esophageal cancer treated with PDT (argon dye laser after intravenous injection of hematoporphyrine derivative) was studied immunohistochemically for p53 protein nuclear accumulation and bcl-2 cytoplasmic expression. Patients with residual disease after two rounds of PDT received definitive radiotherapy. In a subsequent in vitro study, W138 human lung fibroblasts and W138-SV-40 virus transformed were assessed for their sensitivity to PDT. The constitutive bcl-2 overexpression of the transformed cells vs. normal cells (assessed with RT-PCR) was 16-fold. RESULTS Positive bcl-2 and p53 expression was noted in 10 out of 36 (27%) and 14 out of 36 (39%) patients, respectively. Seven out of 11 tumors (63%) with bcl-2 expression responded completely to PDT vs. 6 out of 26 (23%) of cases with no bcl-2 expression (p = 0.02). No association of p53, T-stage and of histology grade with response to PDT or PDT/RT was noted. The sensitivity to PDT of transformed human fibroblasts compared to normal ones was 4 times more at a fluence of 4.3 J/cm2 (4% vs. 1% cell kill) as well as at a fluence of 5.4 J/cm2 (8% vs. 2% cell kill). CONCLUSION Bcl-2 protein expression is associated with favorable response to PDT and can be used as a predictor of cancer response to PDT. This finding can be explained by experimental studies showing that PDT induces selective degradation of the bcl-2 protein, leading to apoptosis by decreasing the bcl-2/bax ratio. Studies on PDT combination with agents targeting bcl-2 (i.e. taxanes) are on going to eventually assess a super-additive effect.

Abstract
Multigate analysis is known to be capable of detecting accurate blood velocity profiles from human vessels. Experimental systems so far presented in the literature use time-domain frequency estimations and, more recently, the fast Fourier transform (FFT) for real-time analysis of Doppler signals from multiple range cells. This experimental study is aimed at evaluating the application of an autoregressive (AR) method (Burg algorithm) to multigate Doppler analysis. Both in vitro and in vivo results were collected with a commercial Duplex scanner coupled with a prototype multigate unit developed in our laboratory. The same multigate signals are, thus, processed according to both the FFT and the Burg algorithms. The related spectral and maximum frequency profiles are reported and statistically compared. AR, implemented with the Burg algorithm, is demonstrated to be a way to perform multigate spectral analysis with reduced spectral variance, suitable for maximum velocity profile extraction through a simple threshold.

Abstract
PURPOSE Photodynamic therapy (PDT) has shown remarkable activity in a variety of human cancers. In the present study, we report the effects of PDT on inoperable early-stage esophageal cancer. METHODS AND MATERIALS Sixty-two patients were treated with an argon dye laser (630 nm wavelength, 300-800 mW of power, energy dose of 200-300 J/cm) after intravenous injection of 5 mg/kg of hematoporphyrin derivative. Eighteen patients (29.5%) had in situ carcinoma (Tis), 30 (48.5%) had T1-stage cancer, 7 (11%) had T2-stage cancer, and 7 (11%) had recurrent disease in the anastomotic area after previous surgery without evidence of invasion outside the lumen. Patients with residual disease after two rounds of PDT received definitive radiotherapy. Patients were evaluated for response to therapy and survival. The follow-up time ranged from 3 to 90 months (median, 32 months). RESULTS The complete response (CR) rate was 37% (23 of 62) in patients who received PDT alone and 82% (51 of 62) in those who also received radiotherapy. The CR rate after PDT alone was statistically higher (p = 0.04) for patients who had Tis/T1 lesions (21 of 48; 44%) than for those with T2-stage disease (2 of 7; 28%) or recurrent tumors (0 of 7; 0%). Fifty-two percent of patients who had CR following PDT alone did not suffer local tumor recurrence. The median local progression-free survival times after PDT and additional radiotherapy (in cases with incomplete response) was 49 months for Tis- and T1-stage lesions, 30 months for those with T2-stage disease, and 14 months for patients with locally recurrent disease. Patients who completely responded to PDT had a median overall survival (OS) of 50 months, which was significantly longer (p < 0.003) than that of patients not responding to PDT. Toxicity was minimal; we recorded three cases of esophageal stenosis (7%) and one case of tracheo-esophageal fistula (2.5%) after combined PDT and radiotherapy. CONCLUSION PDT is an effective regimen for early esophageal cancer, giving a CR rate of about 40%, long-term local control and favorable overall survival. Additional radiotherapy in cases of incomplete response to PDT is effective and potentially curative in another 45% of cases.

Abstract
Recent series reported increasing incidence of esophageal and cardial cancers with prognosis still severe in spite of surgical progress. The late diagnosis reduces the chance of radical surgery; on the other hand about 80-90% of patients develop local or distant recurrence. Therefore the treatment of esophageal and cardial cancer is often palliative: surgical resection is reserved only to selected cases. Endoscopic palliation was the treatment of choice in a total of 265 patients 174 of which received laser therapy and 91 prosthesis intubation. The results it good in about 80% of cases.

Abstract
In the period 1993-1997 we performed two phase II pilot studies of first-line chemo-radiotherapy in patients with locally advanced (T4) SCC of the esophagus. The first protocol (3 cycles of DDP-VP16 + 45 Gy) was used in 37 patients: toxicity was not negligible; a clinical tumor downstaging was obtained in 54% of cases; an R0 resection surgery was performed in 40% of patients. The overall median survival of the whole group of 37 patients was 11 months, while it was > 36 months for patients undergoing R0 resection. The second protocol (4 cycles of DDP-5FU + 45 Gy) was used in 25 patients: a clinical tumor downstaging was obtained in 55% of cases, and R0 resection surgery was performed in 45% of patients. The overall median survival of the whole group was 11 months. To date, all patients but one (who died after 13 months) are alive with a median follow up of 13 months. The prognosis of both groups of patients was improved compared to patients with T4 SCC of the esophagus who did not undergo chemo and/or radiotherapy. The survival advantage was especially evident for those who were able to undergo an R0 resection. First line chemo-radiotherapy should be considered the standard treatment for locally advanced esophageal SCC.

Abstract
UNLABELLED We studied the outcome of our 68 cervix carcinoma patients treated either with: 1) radical surgery and postoperative 192Ir high-dose rate afterloading brachytherapy or postoperative radiotherapy to the whole pelvis or with 2) standard hysterectomy and postoperative radiotherapy to the whole pelvis. Forty-eight women were treated by radical hysterectomy from 1988 to 1992 and--due to risk factors--by postoperative radiotherapy (Group 1), 20 other patients (Group 2) pretreated with standard hysterectomy were admitted to the university hospital for postoperative radiotherapy of the whole pelvis. Postoperative radiotherapy consisted of 39.6 Gy total dose using the box technique, plus two afterloading applications with a single dose of 7.5 Gy and 6 Gy external beam therapy to the pelvic lymph nodes sparing the midline. Comparing the Kaplan-Meier plots of both groups, the tumor related survival curve, the locoregional control and the rates of metastatic disease were nearly identical. But in the analysis of special subgroups, patients with positive lymph nodes after standard hysterectomy and postoperative radiotherapy had a worse prognosis (75% three years' survival rate) than patients after radical surgery (86% three years' survival rate). Lymphangiosis was a negative prognostic factor for the patients pretreated with standard hysterectomy (60% versus 80% three years' survival rate), but not for patients after radical surgery (80% three years' survival rate), despite the same radiotherapy in both groups. CONCLUSION Standard hysterectomy fails to be an adequate treatment for early cervix carcinoma because moderately dosed postoperative radiotherapy cannot achieve complete locoregional control in all cases of positive lymph nodes or invasion of lymph vessels. However, based on the empirical results of many authors and our own results, postoperative radiotherapy is further indicated in high risk cases of cervix carcinoma after radical surgery.

Abstract
Since 1982, our department has used photodynamic therapy (PDT) in the treatment of loco-regional recurrences of gynaecological cancers. We have treated 26 patients in this time. In the majority of cases the site of vaginal recurrences was the vaginal vault. The light sources were an Argon-dye laser (Meditec) and, in some cases, a CO2 laser. The light dose ranged between 60 and 500 J cm-2. The photosensitizing drug used was Hematoporphyrin (HP) (Monico Farmaceutici) at the dose of 5 mg kg-1 body weight. Patients were evaluated 45 days after the treatment with a gynaecological examination and after 75-90 days with a vaginal smear. The results were divided into 2 groups: objective and symptomatic. The symptomatic response concerned only the patients treated with a palliative aim and, in this case, a complete response (CR) was a complete absence of symptoms at least for 60 days. In this group the complete response rate was 66%. In the curative group, the complete response was a cytological and/or histological absence of lesions. In this group we had 12 CR (70.58%). The survival rate was also evaluated. A significant review of the photodynamic therapy in gynaecological neoplasms has also been done.

Abstract
The incidence of locoregional recurrences of gynecological tumors is still a major problem. Many authors suggest that it is the major cause of death in patients affected by cervical-endometrial cancers. The results achieved by retreating these patients with conventional therapies are still unsatisfactory. Since 1982, in our department, we have been using photodynamic therapy (PDT) for treatment of locoregional recurrences in gynecological cancers. We have treated 26 patients. In the majority of the cases, vaginal recurrences were on the vaginal vault. Out of 26 cancers, 17 were epidermoid cancers. Lasers used were the argon dye laser (Meditec) and, in some cases, the CO2 laser. Light dose ranged between 60 and 500 J/cm2. The photosensitizing drug used was hematoporphyrin (HP) (Monico Farmaceutici, Venezia, Italy) at a dose of 5 mg/kg body weight. Patients were evaluated 45 days after treatment with gynecological examination and again after 75-90 days with a vaginal smear. Results were divided into 2 groups: objective and symptomatic. The symptomatic response concerned only patients treated with a palliative aim and, in this case, a complete response (CR) was a complete absence of symptoms for at least 60 days. In this group the complete response rate was 66.6%. In the curative group, the complete response was a cytological and/or histological absence of lesion. In this group we had 12 CR (70.58%). The survival rate of patients treated only with PDT ranged between 3 and 92 months (mean 50.7 months). No major acute or side effects were recorded.

Abstract
We studied 2000 dyspeptic patients with no obvious signs of organic disease at their first examination, in order to (1) verify how many diagnoses of idiopathic dyspepsia had really been made after exhaustive diagnostic procedures and (2) evaluate the diagnostic power of the symptoms in distinguishing organic from idiopathic dyspepsia. This latter was considered only when no structural abnormalities were found. In all the other cases, a distinction was made between "related" and "associated" organic dyspepsia according to whether or not there was a certain relationship between the abnormalities and the dyspeptic symptoms. The patients were referred to us as follows: (1) spontaneously, (2) sent by physicians collaborating with us, (3) referred to our open access endoscopic service. The results show the frequency of idiopathic dyspepsia was 26%, whereas associated structural abnormalities were present in 45.4%. Obvious organic causes of dyspepsia were seen in 28.6% (24% benign and 4.6% malignant diseases). When considered separately, no symptom alone allows a correct diagnosis. The simultaneous evaluation of the symptoms with linear discriminant analysis distinguishes between idiopathic and organic dyspeptic patients in about 70% of the cases. A higher discrimination percentage in about 70% of the cases. A higher discrimination percentage could probably be obtained using a wider range of clinical parameters and/or a more complex statistical analysis of the interrelationships which exist between the clinical symptoms and the final diagnosis.

Abstract
Photodynamic therapy (PDT) with porphyrins and red light is receiving increasing attention in the management of malignant tumours. At present PDT is primarily indicated for the treatment of superficial or early-stage lesions. At the Department of Radiotherapy and the First Institute of Surgery in Padova (Italy) more than 150 cases of tumours of different types have been treated using this technique. This paper briefly describes 21 cases of superficial oesophageal cancer. A complete response was observed in 11 of 21 cases. Radiation therapy appeared to be very effective as a salvage treatment of non-response patients.

Abstract
The present study was performed to determine the effect of the duration of chronic caerulein administration given at different doses, on the rat pancreas. Four groups of rats, one treated with 0.9% NaCl (control) and the others with caerulein 2, 5 and 10 micrograms/Kg twice a day i.p. were used. After a treatment period of 15, 30 and 60 days, 6 rats from each group were anesthetized, the pancreas was removed, and growth and composition of pancreatic tissue were determined. Small samples were taken for histological examination. Caerulein induced pancreatic hyperplasia and hypertrophy. The dose of caerulein used and the length of the treatment did not significantly modify the trophic effect. Focal perivascular and periductular lymphomonocytic infiltrates associated with cellular abnormalities were seen at 30 and 60 days. The results suggest that 1) the trophic effect of caerulein is not dose-and-time dependent and 2) morphological abnormalities can appear during long term treatment with CCK analogous.
